Description

Atomization device

This disclosure claims the priority of the Chinese patent application filed with the Chinese Patent Office on November 03, 2022, with application number 202222932823.0 and application name “Atomization Device”, the entire contents of which are incorporated by reference in this disclosure.

Technical Field

The present disclosure relates to the field of atomization technology, and in particular to an atomization device.

Background technique

The atomization device can be an electronic cigarette loaded with conventional electronic cigarette oil, or it can be a medicinal atomization device loaded with medicinal CBD (cannabidiol) oil, or medicinal THC (tetrahydrocannabinol) oil. The heating element inside it can heat the oil (including conventional electronic cigarette oil, CBD oil, THC oil, etc.) to form smoke, and output it through the filter of the atomization device for users to inhale.

At present, the oil in the atomization device penetrates into the heating element in the atomization chamber under the action of gravity. Taking the traditional ceramic core atomization equipment as an example, the oil is on the top and the ceramic is on the bottom. Under the action of gravity, the oil penetrates downward through the ceramic to the heating area at the bottom of the ceramic. When sucking, the negative pressure of the air accelerates the penetration and atomization volatilization of the oil.

However, the above-mentioned oil guiding method has the following problems: first, if the penetration rate of the oil guiding material itself is slightly inaccurate, it will cause the oil to penetrate too quickly or too slowly, thereby causing oil leakage or dry burning of the heating element; second, during the oil seepage process, a precise air duct needs to be designed to replenish air in the oil tank, otherwise a negative pressure in the oil tank will be formed, resulting in the oil not being able to flow down and the heating element being dry burned, and the air duct connects the oil tank to the outside atmosphere, increasing the risk of oil leakage or oil volatilization.

Detailed ways

In order to make the above-mentioned objects, features and advantages of the present disclosure more obvious and easy to understand, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

In conventional atomization devices, the power source for the oil to penetrate the oil-conducting material and enter the atomization chamber (or contact the heating element) is traditional gravity. Because gravity is vertically downward, the oil must be on top and the oil-conducting material must be on the bottom. Once the infiltration is too fast, the oil will pass through the oil-conducting material and enter the lower space and flow everywhere. There is a risk of oil leakage in any silicone seal, especially when taking an airplane or entering extremely cold or high-temperature areas where the surrounding environment changes drastically, which greatly increases the probability of oil leakage.

In addition, the oil that falls along the oil-conducting material will adhere to the smoke formed by the oil atomization and be inhaled into the mouth through the narrow airway, which has become a major pain point in the industry. By reducing the porosity of the oil-conducting material, the oil-passing capacity is reduced. When the heating element is working, the oil infiltration speed is slow, resulting in insufficient oil supply, which in turn causes the heating element to dry burn more seriously.

In addition, the space of a traditional oil storage chamber is fixed. As the oil atomization proceeds, if the oil becomes less, air must enter the oil storage chamber simultaneously. Otherwise, negative pressure will be generated in the oil storage chamber, resulting in the oil in the oil storage chamber being unable to enter the atomization chamber through the oil guide material. Using an air duct connecting the outside atmosphere and the oil storage chamber to replenish air in the oil storage chamber can easily cause oil volatilization and leakage. Even if some sophisticated leak-proof design is made for the air duct, it cannot guarantee 100% safety and oil leakage may still occur.

Based on this, an atomization device is provided in the embodiment of the present disclosure, the core concept of which is that the power for the oil to enter the atomization chamber comes from the pre-stored energy of the spring, not relying on gravity, so it can be arranged with the oil-conducting material and the atomization chamber on top and the oil on the bottom. In this way, even if the oil penetrates quickly, it can be ensured that after passing through the oil-conducting material, it will flow above the oil-conducting material under the action of gravity and will not flow everywhere. And the occurrence of dry burning of the heating element can be prevented by slightly increasing the porosity of the oil-conducting material or the spring pressure. When the atomization device is not in working state, the spring can be used to unload the force to isolate the oil and the oil-conducting material, further preventing the occurrence of oil leakage.

In addition, the oil-conducting material in the atomizing device of the present disclosure extends from the bottom into the atomizing chamber, and the internal space of the atomizing chamber and the suction nozzle is relatively large, which is not a traditional narrow airway. Even if the oil penetrates into the atomizing chamber too quickly, too much oil will flow above the oil-conducting material and below the atomized smoke. Then, the oil is not easy to adhere to the smoke formed by atomization and be inhaled into the mouth, thereby reducing the risk of the oil being inhaled into the mouth. Moreover, the oil flowing above the oil-conducting material is always in contact with the heating element in the atomizing chamber, and will eventually be atomized by the heating element, so as to solve the problem of oil leakage caused by excessive oil falling into the atomizing chamber and separating from the heating element when the oil penetrates into the atomizing chamber in the traditional way.

Furthermore, in the present disclosure, the space of the oil storage chamber changes constantly under the pressure of the spring, and there will be no problem of negative pressure in the oil storage chamber.

1 , a schematic diagram of the structure of an atomizing device provided in an embodiment of the present disclosure is shown. The atomizing device in the embodiment of the present disclosure includes an atomizing device body 100, an atomizing chamber 200, an oil storage chamber 300, a piston 500, an oil guide material 400 and a pressure regulating device.

Among them, the atomization device can be an electronic cigarette or a medicinal atomization device, and the oil loaded in the oil storage chamber 300 in the atomization device can be conventional electronic cigarette oil, or medicinal CBD oil, medicinal THC oil, or other medicinal essential oils, etc., which can be set according to actual needs, and the present disclosure does not limit this.

A heating element for heating the oil to form smoke is provided in the atomization chamber 200. The shape of the heating element may be needle-shaped, sheet-shaped or cylindrical, etc. The material of the heating element may be iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel or pure titanium, etc. The shape and material of the heating element are not limited in the embodiment of the present disclosure; the oil guiding material 400 is used to guide the oil in the oil storage chamber 300 into the heating element in the atomization chamber 200. The oil guiding material 400 may be ceramic, cotton, non-woven fabric, etc., which may be selected according to actual needs, and is not limited in the embodiment of the present disclosure.

A suction nozzle 110 is provided at one end of the atomizing device body 100, and the atomizing chamber 200 and the oil storage chamber 300 are both located in the atomizing device body 100, and the atomizing chamber 200 is located between the suction nozzle 110 and the oil storage chamber 300, that is, the oil storage chamber 300 is located below the atomizing chamber 200, and the interior of the suction nozzle 110 is communicated with the atomizing chamber 200, so that the heating element in the atomizing chamber 200 heats the oil to form smoke that directly enters the interior of the suction nozzle 110 from the atomizing chamber 200, and the atomizing chamber 200 is connected to the oil storage chamber 300 through the oil guide material 400.

Part of the wall of the oil storage chamber 300 is formed by a movable piston 500. The size of the oil storage chamber 300 can be adjusted by moving the piston 500 to give different pressures to the oil in the oil storage chamber 300. The side of the piston 500 facing away from the oil storage chamber 300 is connected to a pressure regulating device. The pressure regulating device is used to adjust the pressure of the piston 500 on the oil in the oil storage chamber 300 so that the oil in the oil storage chamber 300 can penetrate into the atomization chamber 200 through the oil guide material 400.

Specifically, the oil storage chamber 300 in the atomization device is located below the atomization chamber 200. When the user uses the atomization device, the pressure of the piston 500 on the oil in the oil storage chamber 300 can be adjusted through the pressure regulating device. The pressure replaces gravity, so that the oil in the oil storage chamber 300 penetrates into the heating element in the atomization chamber 200 through the oil-conducting material 400 under the pressure. The user can adjust the required pressure through the pressure regulating device according to his own needs, adjust the desired oil penetration speed, and improve the user experience.

When the user stops using the atomizing device, the pressure of the piston 500 on the oil in the oil storage chamber 300 can be relieved through the pressure regulating device, so that the oil no longer penetrates into the atomizing chamber 200 through the oil guide material 400, further ensuring that there is no oil leakage.

In the disclosed embodiment, the oil storage chamber 300 in the atomization device is located below the atomization chamber 200. The pressure of the piston 500 on the oil in the oil storage chamber 300 can be adjusted by a pressure regulating device, thereby adjusting the penetration speed of the oil into the atomization chamber 200 through the oil-conducting material 400, thereby avoiding oil leakage or dry burning of the heating element due to the oil penetrating too fast or too slow. At the same time, the user can adjust the required pressure and the desired oil penetration speed through the pressure regulating device according to their own needs, thereby improving the user experience.

Moreover, when the oil penetrates too quickly, since the oil-conducting material 400 is located above the oil storage chamber 300, the excess oil will also stay on the surface of the oil-conducting material 400 and will not flow around to cause oil leakage. In the atomizing device, the oil-conducting material 400 extends from the bottom into the atomizing chamber 200. The internal space of the atomizing chamber 200 and the suction nozzle 110 is relatively large, and is not a traditional narrow airway. Even if the oil penetrates into the atomizing chamber 200 too quickly, the excess oil will stay on the surface above the oil-conducting material 400 and below the atomized smoke. In this case, the oil will not easily adhere to the smoke formed by atomization and be inhaled into the mouth, thereby reducing the risk of the oil being inhaled into the mouth.

In addition, when the oil penetrates upward into the atomizing chamber 200 through the oil-conducting material 400, the piston 500 in the oil storage chamber 300 will also move upward as the oil decreases, and no negative pressure will be formed in the oil storage chamber 300. On the one hand, it can prevent the oil from being unable to penetrate into the atomizing chamber 200 upward due to the negative pressure in the oil storage chamber 300, resulting in dry burning of the heating element. On the other hand, there is no need to set up a special airway to replenish air in the oil storage chamber 300, thereby avoiding oil leakage or oil volatilization.

Furthermore, when the user stops using the atomizing device, the pressure of the piston 500 on the oil in the oil storage chamber 300 can be relieved through the pressure regulating device, so that the oil no longer penetrates into the atomizing chamber 200 through the oil guiding material 400, further ensuring that there is no oil leakage.

Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the modified embodiment.

Referring to Fig. 2, a partial enlarged structural schematic diagram of A in Fig. 1 provided in an embodiment of the present disclosure is shown. The atomizing device further includes an exhaust pipe, one end of which is connected to a side of the oil storage chamber 300 close to the atomizing chamber 200, and the other end is connected to the interior of the suction nozzle 110, and a one-way ball valve 900 is provided on the exhaust pipe, and the one-way ball valve 900 has a flow chamber 910 (such as a circular flow chamber 910, an elliptical flow chamber 910, etc.) and a floating ball 920 movably arranged in the flow chamber 910.

Specifically, there are two exhaust ports in the circulation chamber 910, one connected to the oil storage chamber 300, and the other connected to the inside of the suction nozzle 110. Under normal circumstances, the float 920 will block the exhaust port connected to the oil storage chamber 300. If there is air in the oil storage chamber 300, the air is in the upper part and the oil is in the lower part.

One of the purposes of providing the one-way ball valve 900 is to be able to push/pull the piston 500 in the oil storage chamber 300. For example, when the piston 500 is pushed from bottom to top, air can be discharged from the one-way ball valve 900, so the piston 500 can move upward, compressing the space of the oil storage chamber 300, and avoiding the piston 500 being unable to move upward due to high pressure formed by the air in the oil storage chamber 300 when the piston 500 is pushed from bottom to top; when the piston 500 is pulled from top to bottom, air will enter the oil storage chamber 300 from the one-way ball valve 900, so the piston 500 can move downward, increasing the space of the oil storage chamber 300, and avoiding the piston 500 being unable to move downward due to negative pressure formed in the oil storage chamber 300 when the piston 500 is pulled from top to bottom.

When the atomizing device is in use (working), the air in the oil storage chamber 300 needs to be discharged first. Specifically, the piston 500 is pushed upward by the pressure regulating device, and the gas pushes the float 920 to be discharged. After the gas is discharged, the oil enters the circulation chamber 910 and contacts the float 920 to make the float 920 float up, so that the float 920 blocks the exhaust port on the upper side connected to the inside of the suction nozzle 110, thereby sealing the oil storage chamber 300 to prevent the oil from leaking.

When the atomizing device is not in use (not working), the atomizing device can be turned upside down, and the piston 500 can be pulled out through the pressure regulating device to allow the outside air to push the float 920 and enter the oil storage chamber 300. The atomizing device can then be rotated and placed upright. At this time, when there is air in the oil storage chamber 300, the air is at the upper part and the oil is at the lower part. The oil can be separated from the oil guiding material 400 by the air, preventing the oil from penetrating into the oil guiding material 400.

In the above embodiment, the one-way ball valve 900 on the exhaust pipe in the atomization device can be turned on during exhaust and turned off when oil enters the one-way ball valve 900, so that the gas in the oil storage chamber 300 can be discharged through the one-way ball valve 900 while preventing the oil in the oil storage chamber 300 from leaking out.

In an optional embodiment of the present disclosure, the pressure regulating device includes a spring 600 and an upper screw cover 700 .

Among them, the other end of the atomizer device body 100 is provided with an external thread 120, and the upper screw cap 700 is provided with an internal thread 710. The upper screw cap 700 is assembled on the other end of the atomizer device body 100 by matching the internal thread 710 and the external thread 120. The spring 600 is placed in the atomizer device body 100, and one end of the spring 600 is connected to the side of the piston 500 away from the oil storage chamber 300, and the other end is connected to the bottom of the upper screw cap 700. The spring 600 is compressed/relaxed by rotating the upper screw cap 700 to adjust the pressure of the piston 500 on the oil in the oil storage chamber 300.

Specifically, the pressure regulating device can be composed of a spring 600 and an upper screw cover 700. When using the atomizing device, the user can rotate the upper screw cover 700 on the other end of the atomizing device body 100 to move the upper screw cover 700 toward the oil storage chamber 300, thereby compressing the spring 600 between the upper screw cover 700 and the piston 500. Therefore, a pressure can be applied to the piston 500 through the spring 600, so that the piston 500 is pressed against the oil in the oil storage chamber 300, so that the oil penetrates upward through the oil-conducting material 400 into the heating element in the atomizing chamber 200 for heating and atomization. The user can adjust the required pressure and the desired oil penetration speed by rotating the upper screw cover 700 according to their own needs, thereby improving the user experience.

When the user stops using the atomizing device, the upper screw cap 700 can be rotated to move the upper screw cap 700 away from the oil storage chamber 300, thereby relaxing the spring 600 and removing the pressure of the spring 600 on the piston 500, so that the piston 500 no longer presses the oil in the oil storage chamber 300, and the oil in the oil storage chamber 300 no longer penetrates into the atomizing chamber 200 through the oil guide material 400, further ensuring that there is no oil leakage.

In the above embodiment, the pressure of the piston 500 pressed against the oil in the oil storage chamber 300 can be freely adjusted by the spring 600 and the upper screw cap 700, thereby adjusting the penetration rate of the oil into the atomization chamber 200, thereby avoiding oil leakage or dry burning of the heating element due to too fast or too slow oil penetration, thereby improving the user experience.

In another optional embodiment of the present disclosure, the internal thread can also be provided at the other end of the atomization device body 100, and the external thread can also be provided on the upper screw cap 700. The upper screw cap 700 can be assembled on the other end of the atomization device body 100 by cooperating with the internal thread and the external thread. The spring 600 is placed in the atomization device body 100, and one end of the spring 600 is connected to the side of the piston 500 facing away from the oil storage chamber 300, and the other end is connected to the bottom inside the upper screw cap 700. The spring 600 is compressed/relaxed by rotating the upper screw cap 700 to adjust the pressure of the piston 500 on the oil in the oil storage chamber 300.

Specifically, the pressure regulating device can be composed of a spring 600 and an upper screw cover 700. When using the atomizing device, the user can rotate the upper screw cover 700 on the other end of the atomizing device body 100 to move the upper screw cover 700 toward the oil storage chamber 300, thereby compressing the spring 600 between the upper screw cover 700 and the piston 500. Therefore, a pressure can be applied to the piston 500 through the spring 600, so that the piston 500 is pressed against the oil in the oil storage chamber 300, so that the oil penetrates upward through the oil-conducting material 400 into the heating element in the atomizing chamber 200 for heating and atomization. The user can adjust the required pressure and the desired oil penetration speed by rotating the upper screw cover 700 according to their own needs, thereby improving the user experience.

When the user stops using the atomizing device, the upper screw cap 700 can be rotated to move the upper screw cap 700 away from the oil storage chamber 300, thereby relaxing the spring 600 and removing the pressure of the spring 600 on the piston 500, so that the piston 500 no longer presses the oil in the oil storage chamber 300, and the oil in the oil storage chamber 300 no longer penetrates into the atomizing chamber 200 through the oil guide material 400, further ensuring that there is no oil leakage.

In the above embodiment, the pressure of the piston 500 pressed against the oil in the oil storage chamber 300 can be freely adjusted by the spring 600 and the upper screw cap 700, thereby adjusting the penetration rate of the oil into the atomization chamber 200, thereby avoiding oil leakage or dry burning of the heating element due to too fast or too slow oil penetration, thereby improving the user experience.

It should be noted that, in addition to the above-mentioned structure, the pressure regulating device may also adopt other structures, which can be specifically arranged as needed, and the present disclosure does not limit this. For example, the spring 600 is located between the upper screw cover 700 and the piston 500, and a threaded hole is provided at the bottom of the upper screw cover 700. A pressure regulating rod with a thread is assembled in the threaded hole, and one end of the pressure regulating rod is connected to an end of the spring close to the upper screw cover 700. The spring 600 is compressed/relaxed by rotating the pressure regulating rod, thereby adjusting the pressure of the piston 500 on the oil in the oil storage chamber 300.

In another optional embodiment of the present disclosure, the piston 500 includes a piston body 510 and a piston rod 520.

Among them, the piston rod 520 is connected to the side of the piston body 510 facing away from the atomization chamber 200, and the spring 600 is sleeved on the piston rod 520, one end of which is connected to the side of the piston body 510 facing away from the atomization chamber 200, and the other end is connected to the bottom inside the upper screw cover 700. A through hole compatible with the piston rod 520 is also provided at the bottom of the upper screw cover 700, and the end of the piston rod 520 away from the piston body 510 passes through the through hole and is placed outside the atomization device body 100.

Specifically, when the user does not need to use the atomizing device, the user can rotate the upper screw cap 700 to move the upper screw cap 700 away from the atomizing chamber 200, and then pull the piston rod 520 disposed on the outside of the atomizing device body 100 to move the piston 500 away from the atomizing chamber 200, thereby preventing the piston 500 from pressing against the oil in the oil storage chamber 300, thereby preventing the oil in the oil storage chamber 300 from seeping into the atomizing chamber 200 through the oil guide material 400, further ensuring that there is no oil leakage.

In another optional embodiment of the present disclosure, a sealing ring 512 is provided between the side wall of the piston body 510 and the side wall of the oil storage chamber 300 .

Specifically, a groove (sealing ring groove) 511 can be provided on the side wall of the piston body 510 to accommodate the sealing ring 512. When the side wall of the piston body fits with the side wall in the oil storage chamber 300, the sealing of the oil storage chamber is achieved through the sealing ring 512. Referring to FIG3, a partial enlarged structural schematic diagram of FIG1B provided in an embodiment of the present disclosure is shown. The side wall of the piston body 510 fits with the side wall in the oil storage chamber 300 to form the oil storage chamber 300, and the side wall of the piston body 510 is provided with a groove 511 for accommodating the sealing ring 512. When the side wall of the piston body 510 fits with the side wall in the oil storage chamber 300, the sealing of the gap between the side wall of the piston body 510 and the side wall in the oil storage chamber 300 is achieved through the sealing ring in the groove 511, thereby preventing the oil in the oil storage chamber from leaking out.

It should be noted that, in addition to being arranged in the groove 511, the sealing ring 512 may also be arranged in other ways, which is not limited by the present disclosure. For example, the entire piston body 510 can be wrapped with a sealing material, and when the side wall of the piston body 510 is in contact with the side wall of the oil storage chamber 300, the sealing of the oil storage chamber 300 is achieved by the sealing material.

In another optional embodiment of the present disclosure, the atomization device further includes an airflow sensing channel 800 , an airflow sensor 830 and a battery 830 .

Among them, the airflow sensing channel 800 is arranged outside the atomizer body 100, and the air inlet 810 of the airflow sensing channel 800 is connected to the outside of the atomizer body 100, the air outlet 820 of the airflow sensing channel 800 is connected to the inside of the suction nozzle 110, the airflow sensor 830 and the battery 830 are located in the airflow sensing channel 800, and the airflow sensor 830, the battery 830 and the heating element in the atomizer chamber 200 are connected in series through a wire.

Specifically, when the user inhales smoke from the mouthpiece 110 of the suction nozzle 110, there is airflow flowing through the inside of the suction nozzle 110, and there is airflow entering the airflow sensing channel 800 from the air inlet 810 of the airflow sensing channel 800 and flowing out from the air outlet 820 of the airflow sensing channel 800, and then the airflow sensor 830 installed in the airflow sensing channel 800 will sense the airflow passing, therefore, the airflow sensor 830 in the series circuit is turned on, the battery 830 supplies power to the heating element, and the heating element heats up to heat the oil into smoke; when the user stops inhaling smoke, the airflow sensor 830 does not sense the airflow passing, at this time the airflow sensor 830 in the series circuit is turned off, and the battery 830 stops supplying power to the heating element.

In the above embodiment, when the user inhales smoke, the airflow sensor 830 in the series circuit is turned on, the battery 830 supplies power to the heating element, and the heating element heats up to heat the oil into smoke. When the user stops inhaling smoke, the airflow sensor 830 in the series circuit is turned off, and the battery 830 stops supplying power to the heating element. On the one hand, it can prevent the battery 830 from continuously supplying power to the heating element, causing the heating element to have an excessively high temperature and burn the atomization device, and causing harmful gases and burnt substances to be inhaled into the human body and endanger human health. On the other hand, it can bring a good smoking effect and give the user a good smoking experience.

In another optional embodiment of the present disclosure, the atomization device also includes an oil cup, and the oil cup includes an oil cup side wall and an oil cup upper cover. The oil cup side wall, the oil cup upper cover and the piston 500 form an oil storage chamber 300 for containing oil. Specifically, the piston body 510 serves as the oil cup lower cover of the oil cup. The piston body 510 is placed in the oil cup, and the side wall of the piston body 510 is in contact with the side wall of the oil cup. The chamber formed between the piston body 510 and the oil cup upper cover and the side wall of the oil cup is the oil storage chamber 300.

In another optional embodiment of the present disclosure, the atomizing device further includes oil storage cotton, which is located in the oil storage chamber 300 and is used to store oil. The speed at which the oil penetrates into the atomizing chamber can be slowed down by the oil storage cotton. It should be noted that in addition to the oil storage cotton that can be provided in the oil storage chamber of the present disclosure, the oil storage chamber can also be provided without the oil storage cotton, and the oil can be directly loaded in the oil storage chamber, or other oil storage materials can be provided to store the oil. The specific configuration can be as needed, and this is not limited in the present disclosure.
