An annular sealing portion 514 is also provided in the circumference of the oil sealing portion 512. The sealing portion 514 can be embedded in the liquid storage tank 5 by interference fit to prevent oil leakage.

An assembly portion 513 is also provided above the oil sealing cover top plate 511 . During the automated assembly process, the machine grabs the assembly portion 513 to align the oil sealing cover top plate 511 with the top of the liquid storage tank 5 , thereby facilitating interference fit of the oil sealing portion 512 in the liquid storage tank 5 .

Preferably, the oil sealing cover 51 is made of silicone or other soft rubber materials.

Preferably, the top of the liquid storage tank 5 can be provided with an oil filling port or an oil filling pipe extending upward for injecting atomized liquid into the liquid storage tank 5, instead of using the above-mentioned oil sealing cap 51; the oil filling port or the oil filling pipe is closed by an oil blocking plug, and the oil blocking plug is removed when the liquid storage tank 5 needs to be filled with oil. The oil filling port or the oil filling pipe can also be provided on the side wall of the liquid storage cartridge 1. Alternatively, the top of the liquid storage tank 5 is closed, and the liquid storage cartridge 1 can only be used once, and atomized liquid cannot be added.

Furthermore, a liquid storage cartridge top cover 102 is provided on the top of the liquid storage cartridge 1, and the liquid storage cartridge top cover 102 is located above the oil sealing cover 51. The liquid storage cartridge top cover 102 is installed on the top of the liquid storage cartridge 1 by interference fit. In FIG4 , the top surface of the partition wall 106 is lower than the top surface of the liquid storage cartridge 1, leaving space for installing the liquid storage cartridge top cover 102. An air outlet 103 is provided on the liquid storage cartridge top cover 102, and the air outlet 103 is communicated with the airway 105.

Further, in Fig. 3, a liquid guide tube 6 is provided at the bottom of the liquid storage bin 5, and the atomized liquid in the liquid storage bin 5 flows out from the liquid guide tube 6. The liquid guide tube 6 is located at the center of the cross section of the liquid storage bomb 1 where it is located, and the liquid guide tube 6 and the liquid storage bin 5 are transitionally connected by a tapered portion 52, and the tapered portion 52 facilitates the atomized liquid in the liquid storage bin 5 to quickly flow into the liquid guide tube 6.

Furthermore, in FIG. 3 , the outer side of the liquid guiding tube 6 is wrapped with a one-way valve 7 , and the interior of the one-way valve 7 is embedded with a liquid guiding device 8 .

As shown in FIG. 7 , as the first embodiment of the one-way valve 7, a layer of oil sealing film 71 is arranged inside the one-way valve 7. The oil sealing film 71 is located below the liquid guiding tube 6 and above the liquid guiding device 8. Between the liquid guiding tube 6 and the liquid guiding device 8. The oil sealing film 71 is provided with an oil passing slit 72, which is sealed together in a natural state, and the gap is narrow, so the atomized liquid will not flow downward; when the ejector pin 9 passes through the oil passing slit 72, the oil passing slit 72 is cracked and transformed into an oil passing hole, and the atomized liquid begins to flow downward from the liquid guiding tube 6 to the liquid guiding device 8.

Preferably, in Fig. 7, the shape of the oil-passing slot 72 is a straight line. When the shape of the oil-passing slot 72 is a straight line, the atomized liquid flows slowly, and the heating component 4 can fully atomize the atomized liquid.

Furthermore, the oil-passing slit 72 may also be in a cross shape; or in a three-pointed star shape, that is, three slits extend from the center of the oil sealing film 71 to the edge, and the angle between two adjacent slits is 120°; or multiple slits may extend evenly from the center of the oil sealing film 71 to the edge, such as a T-shaped slit, four slits (refer to the cross-shaped slit), five slits, six slits, or other shapes.

Further, as shown in Fig. 8 and Fig. 9, as the second embodiment of the one-way valve 7, a layer of oil sealing film 71 is arranged inside the one-way valve 7, and the oil sealing film 71 is located above the liquid guiding device 8; an oil hole 73 is arranged on the oil sealing film 71, and an oil blocking cover 74 that can close the oil hole 73 is hinged on the edge of the oil hole 73, and the oil blocking cover 74 covers the top of the oil hole 73 in a natural state, and the atomized liquid will not flow downward; when the ejector pin 9 passes through the oil hole 73, the oil blocking cover 74 is pushed open, and the oil hole 73 is exposed, and the atomized liquid begins to flow downward from the liquid guiding tube 6, passes through the oil hole 73 and reaches the liquid guiding device 8.

Preferably, the one-way valve 7 is made of silicone material, so that the oil-passing slit 72 or the oil-blocking cover 74 on the oil-sealing film 71 has the ability to elastically recover after being deformed.

Preferably, in the present invention, other valves may be used to replace the one-way valve 7 , as long as they can be opened by the ejector pin 9 .

Further, as shown in FIG. 10 , as a first embodiment of the liquid guiding device 8, a puncture slit 81 is provided in the center of the liquid guiding device 8, and the puncture slit 81 runs through the entire liquid guiding device 8. The ejector pin 9 can pass through the puncture slit 81 in the middle of the liquid guiding device 8 to open the one-way valve 7. When the ejector pin 9 passes through the puncture slit 81, the puncture slit 81 will be deformed to form a puncture hole. The puncture slit 81 can be in the shape of a straight line, a cross, a three-pointed star, etc.

As shown in FIG11 , as the second embodiment of the liquid guiding device 8 , a central hole 82 is provided in the center of the liquid guiding device 8 , and the central hole 82 runs through the entire liquid guiding device 8 , and the ejector pin 9 can pass through the central hole 82 in the middle of the liquid guiding device 8 to open the one-way valve 7 .

The material of the liquid guiding device 8 can be non-woven fabric, glass fiber cotton, powder metallurgy, linen cotton, porous ceramics, etc. By selecting a suitable material, a suitable oil storage capacity and penetration effect can be obtained.

Further, in conjunction with FIG. 12 and FIG. 13, the host body 2 includes an upper sleeve 21 and a lower sleeve 22. The interior of the upper sleeve 21 is provided with a liquid storage cartridge sealing seat 11 and a liquid storage cartridge limiting sleeve 12 from top to bottom for the liquid storage cartridge 1 to pass through. The liquid storage cartridge sealing seat 11 and the liquid storage cartridge limiting sleeve 12 are both hollow sets, which are adapted to the outer diameter of the liquid storage cartridge 1, and can limit the liquid storage cartridge 1, ensuring that the ejector pin 9 in the lower sleeve 22 can accurately Align the center of the liquid guiding device 8.

Preferably, a sealing ring 13 is embedded inside the liquid storage spring limiting sleeve 12, and the sealing ring 13 can prevent the leakage of atomized gas and prevent dust and water.

Preferably, in Figure 13, a mounting bracket 14 is provided inside the lower sleeve 22, and a first mounting cavity 141 for mounting the heating component 4 is provided on the top of the mounting bracket 14. The mounting bracket 14 is also provided with a second mounting cavity 142 for mounting the battery 15 and a third mounting cavity 143 for mounting the control circuit board 16. The battery 15 and the control circuit board 16 are electrically connected, and the control circuit board 16 is also electrically connected to the heating component 4.

The above-mentioned liquid storage cartridge installation cavity 3 is composed of the hollow part of the liquid storage cartridge sealing seat 11 and the liquid storage cartridge limiting sleeve 12 and a part of the first installation cavity 141. A heating component 4 is arranged at the bottom of the liquid storage cartridge installation cavity 3, and the heating component 4 is specifically arranged in the first installation cavity 141.

Preferably, the upper end of the lower sleeve 22 is also provided with a mounting bracket limiting sleeve 19, which is used to limit the mounting bracket 14 to prevent the mounting bracket 14 from moving up and down, and can also play an external decorative role. At the same time, the upper side of the mounting bracket limiting sleeve 19 is also threadedly connected to the liquid storage spring limiting sleeve 12.

14 to 17 , the liquid guiding device 8 corresponds to the heating component 4 in the main body 2 , and a pin 9 for passing through the liquid guiding device 8 and opening the one-way valve 7 is also provided at the bottom of the liquid storage cartridge installation cavity 3 .

The ejector pin 9 can pass through the center of the liquid guiding device 8 to open the one-way valve 7. At this time, the atomized liquid in the liquid storage tank 5 flows to the liquid guiding device 8 through the liquid guiding tube 6. The liquid guiding device 8 can penetrate the atomized liquid. The heating component 4 in the main body 2 generates heat to atomize the atomized liquid to produce atomized gas.

A battery 15 and a control circuit board 16 are disposed in the host body 2. The battery 15 is used to supply power to the control circuit board 16. The control circuit board 16 is electrically connected to the heating component 4 to control the heating of the heating component.

It can be seen that the atomized liquid in the liquid storage tank 5 will flow downward only after the one-way valve 7 is opened by the ejector pin 9, that is, the one-way valve 7 will be opened only when the liquid storage cartridge 1 is accurately installed inside the main body 2; when the liquid storage cartridge 1 is pulled out of the main body 2, the one-way valve 7 is automatically closed to prevent the atomized liquid from flowing downward.

In conjunction with FIG. 3 and FIG. 14 , the bottom of the liquid storage cartridge 1 is provided with a first air inlet 1041, the outer wall of the liquid storage cartridge 1 is provided with a second air inlet 1042, and the second air inlet 1042 is located above the first air inlet 1041. An air passage 105 is also provided inside the liquid storage cartridge 1, and the second air inlet 1042 is connected to the air outlet through the air passage 105. When the liquid storage cartridge 1 is inserted into the liquid storage cartridge installation cavity 3, a drainage channel 1043 connecting the first air inlet 1041 and the second air inlet 1042 is formed between the outer wall of the liquid storage cartridge 1 and the inner wall of the liquid storage cartridge installation cavity 3. After the atomized liquid is atomized into atomized gas, it passes through the first air inlet 1041, the drainage channel 1043, the second air inlet 1042, the air passage 105, the air outlet 103 in sequence, and finally enters the user's mouth.

Preferably, in FIG. 3 , the first air inlet hole 1041 is connected to the bottom surface of the liquid storage bomb 1 to form a gap; of course, the first air inlet hole 1041 may not be connected to the bottom surface of the liquid storage bomb 1 .

In the present application, each of the first air inlet hole 1041 and the second air inlet hole 1042 has at least one, and the number of the first air inlet hole 1041 and the second air inlet hole 1042 can also be two, three, four, five, etc., as long as It only needs to be able to communicate through the drainage channel 1043.

Preferably, as can be seen in FIG. 14 , the second air inlet hole 1042 is located above the one-way valve 7 in the vertical height direction; a sealing ring 13 is provided in the main body 2, and the second air inlet hole 13 is located below the sealing ring 13 in the vertical height direction.

Preferably, the second air inlet hole 1042 is circular, rectangular or irregular in shape.

Furthermore, the heat generating component 4 in the main body 2 generates heat to atomize the atomized liquid in the liquid guiding device 8 to generate atomized gas, and the atomized gas flows from the first air inlet 1041 through the drainage channel 1043 and the second air inlet 1042 into the airway 105. Since there is a certain height difference between the first air inlet 1041 and the second air inlet 1042, the condensed liquid generated by the atomized gas during the rising process will drip downward under the influence of its own gravity and will not enter the second air inlet 1042, so that no large condensation effect will be generated at the second air inlet 1042, and accordingly no large condensed water droplets will be formed and sucked into the human mouth; in this way, the condensed liquid can be prevented from being sucked into the mouth.

Furthermore, since the liquid guiding tube 6 is fully wrapped by the one-way valve 7, the atomized liquid in the liquid guiding tube 6 will not leak out from the gap into the airway 105, and a good sealing effect is achieved.

Furthermore, in FIG. 14 , a sealing device 10 is provided in the liquid storage bin 5. The sealing device 10 is used to seal the liquid guide tube 6 to prevent the atomized liquid in the liquid storage bin 5 from flowing downward along the liquid guide tube 6. When the ejector pin 9 opens the one-way valve 7, the sealing device 10 will also be pushed open so that the sealing device 10 will no longer seal the liquid guide tube 6.

It can be seen that the sealing device 10 is disposable for the liquid guide tube 6. This sealing is suitable for transportation and storage. When the liquid storage cartridge 1 is first installed in the main body 2, the sealing device 10 will be pushed open by the ejector pin 9. When the liquid storage cartridge 1 is separated from the main body 2, the sealing device 10 no longer seals the liquid guide tube 6, or cannot completely seal it, so the one-way valve 7 performs full or partial sealing. For example: when the sealing device 10 is made of metal or glass, the specific gravity of the sealing device 10 is greater than the specific gravity of the atomized liquid, and when the liquid storage cartridge 1 is placed vertically, the sealing device 10 will naturally fall into the liquid guide tube 6 to block it, achieving a certain sealing effect; this method is related to the material of the sealing device 10 and the placement direction of the liquid storage cartridge 1.

Preferably, the sealing device 10 may be made of plastic or silicone. When the sealing device 10 is pushed open by the ejector pin 9 , the sealing device 10 floats in the atomized liquid.

The one-way valve 7 is different from the sealing device 10. When the liquid storage cartridge 1 is separated from the main body 2, the oil gap 72 inside the one-way valve 7 elastically recovers from the cracked state to the closed state, or the oil retaining cover 74 elastically recovers from the open state to the closed state; together with the surface tension of the atomized liquid, a sealing effect is produced. Therefore, the one-way valve 7 can continuously seal the liquid storage cartridge 1 completely or partially to prevent the atomized liquid from leaking. The main function of the one-way valve 7 is to prevent the atomized liquid from leaking from the liquid storage cartridge 1 when the user takes out the liquid storage cartridge 1 from the main body 2 where the atomized liquid has not been consumed.

It can be seen that in the present application, the one-way valve 7 itself can play a certain sealing role on the atomized liquid. The liquid storage cartridge 1 can use only the one-way valve 7 to seal the atomized liquid, but a sealing device 10 can also be added to the liquid storage bin 5 to further enhance the sealing effect of the liquid storage cartridge 1 before use, so as to strengthen the leakage protection of the liquid storage cartridge 1 in harsh environments such as transportation, storage, vibration, negative pressure, and high temperature.

Preferably, the sealing device 10 is interference fit with the catheter 6. When the cross section of the catheter 6 is circular, the sealing device 10 is in the shape of a sphere; when the cross section of the catheter 6 is square, the sealing device 10 is in the shape of a cube. The sealing device 10 may also be in other shapes, adapted to the cross section of the catheter 6. In the present application, the cross section of the catheter 6 is circular, and the sealing device 10 is a sphere. The sealing device 10 may be made of metal, glass, silicone, plastic, etc., and may play a sealing role.

Further, in FIG15 , the heating component 4 in the liquid storage cartridge installation cavity 3 corresponds to the liquid guide device 8. The heating component 4 includes a heating element 44 and a heating element bracket 43 for fixing the heating element 44; the heating element 44 is electrically connected to the control circuit board 16. When the liquid storage cartridge 1 is accurately installed in the host body 2, the heating element 44 is in contact with the liquid guide device 8, which is convenient for heating the atomized liquid.

Preferably, the heating element 44 is in the form of a sheet, fixed to the heating element bracket 43 and electrically connected to the control circuit board 16 via a conductive pin 45. There are two conductive pins 45, and the heating element 44 is fixed on the top of the two conductive pins 45. The outer contour of the heating element 44 can be circular, rectangular or irregular. The shape of the heating element 44 can also be tubular or other shapes.

The conductive pin 45 is electrically connected to the control circuit board 16 , and the control circuit board 16 can control the temperature of the heating element 44 within an appropriate temperature range through the conductive pin 45 so that the atomized liquid can be fully atomized.

The control circuit board 16 can also control the temperature and output heat work of the heating element 44 within an ideal range by pulse discharge, control of discharge duration, current adaptive discharge, etc. to further improve the atomization effect or achieve other purposes, such as removing impurities such as carbon deposits.

Furthermore, the ejector pin 9 is vertically fixed on the heating element bracket 43, and the ejector pin 9 passes through the center of the heating element 44. The through hole in the center of the heating element 44 can be circular, square or other shapes; in addition to allowing the ejector pin to pass through, the through hole in the center of the heating element 44 also has the characteristics of increasing the heating rate of the heating element 44, enhancing the output power of the control circuit board 16, and facilitating the flow of atomizing gas.

As shown in FIG. 17 , the ejector pin 9 is in a rod-shaped structure as a whole, and a positioning portion 91 is provided near the tail of the ejector pin 9. The positioning portion 91 is sleeved on the ejector pin 9 and is formed integrally with the ejector pin 9. In FIG. 17 , the outer contour of the positioning portion 91 is circular, but it can also be in other shapes, such as rectangular, prism, etc. The head of the ejector pin 9 can also be in a flat surface or rounded corners.

Furthermore, the heating element bracket 43 is a cylindrical structure, and the material used is a high temperature resistant material. The heating element bracket 43 includes a bracket bottom wall 431 and a bracket side wall 432. A bracket fixing portion 433 is provided at the center of the upper surface of the bracket bottom wall 431. A positioning groove 434 adapted to the positioning portion 91 of the ejector pin 9 is provided at the center of the upper surface of the bracket fixing portion 433, and a fixing hole 4341 for the tail of the ejector pin 9 to pass through is provided at the center of the positioning groove 433.

At the same time, after the tail of the ejector pin 9 is inserted into the fixing hole 4341 , the positioning portion 91 of the ejector pin 9 is also just installed in the positioning groove 434 .

Furthermore, the upper surface of the bracket fixing portion 433 is also provided with a pin hole 436 for the conductive pin 45 to pass through, and there are two pin holes 436, which are symmetrically distributed relative to the positioning groove 434, and the pin holes 436 pass through the bracket fixing portion 433.

The airflow guide columns 437 are provided with first airflow guide holes 438, which penetrate the bracket bottom wall 431, and the airflow guide columns 437 are arranged on the left and right sides of the bracket fixing portion 433. In the present application, when the user is inhaling the electronic atomizer, the airflow of the microphone head 41 in the microphone seat 42 disappears and flows upward through the first airflow guide holes 438.

The lower surface of the bracket bottom wall 431 is also vertically provided with mounting posts 439 , and there are two mounting posts 439 symmetrically distributed. The height of the mounting posts 439 is greater than the height of the bracket side wall 432 , that is, the mounting posts 439 are exposed from the bracket side wall 432 .

In the application, the pin holes 436 can be two or more; the number of pin holes 436 depends on the number of conductive pins 45; the first airflow guide hole 438 and the mounting column 439 are not limited to two, and can be one or more, such as three, four, etc.

Combining Figures 3 and 16, it can be seen that the liquid storage cartridge 1 is cylindrical, and a plurality of first protrusions 108 and first recesses 109 are evenly arranged at the bottom along the circumference, and the outer contours of the first protrusions 108 and the first recesses 109 are both continuous and smooth curved surfaces, and a plurality of second recesses 401 and second protrusions 402 are respectively matched with the first protrusions 108 and the first recesses 109 are arranged in the liquid storage cartridge installation cavity 3. When the liquid storage cartridge 1 is installed in the liquid storage cartridge installation cavity 3, the first protrusion 108 and the second recess 401 are matched together, and the first recess 109 and the second protrusion 402 are matched together; the liquid storage cartridge 1 is just accurately installed in the host body 2, and at this time, the heating element 44 is in contact with the liquid guide device 8, which is convenient for heating the atomized liquid.

If the liquid storage cartridge in the present invention is not used, but other liquid storage cartridges are used, then when the other liquid storage cartridge is installed in the host body 2, because it does not have the first protrusion 108 and the first recessed portion 109, or cannot be matched with the host body 2, the other liquid storage cartridge 1 cannot be accurately installed in the host body 2, which will cause the heating element 44 and the liquid guide device 8 to not contact or insufficiently contact, and the atomized liquid cannot be heated well. Therefore, this method can effectively play the role of anti-counterfeiting and identification of the liquid storage cartridge 1, and remind users to use the matching liquid storage cartridge in the present invention.

Preferably, the first protrusion 108 and the first recess 109 have the same shape, where the same shape means that the outer contours of the first protrusion 108 and the first recess 109 are the same, and a first recess 109 is formed between two adjacent first protrusions 108. The liquid bomb 1 is formed by machining a circular quadratic curve equation, and the number of the first protrusions 108 and the first recesses 109 is the same.

Furthermore, the second recessed portion 401 and the second raised portion 402 are disposed on the heating element bracket 43 . Specifically, the second recessed portion 401 and the second raised portion 402 are disposed on the upper surface of the bracket bottom wall 431 .

Therefore, when the liquid storage cartridge 1 is installed in the host body 2, even if the first protrusion 108 and the second recess 401, the first recess 109 and the second protrusion 402 are not completely matched together, since the outer contours of the first protrusion 108 and the second recess 401, the first recess 109 and the second protrusion are all smooth curved surfaces, they will automatically slide and rotate, or the user can slightly rotate the liquid storage cartridge to achieve the first protrusions 108 and the second recesses 401, the first recesses 109 and the second protrusions 402 being snapped together one by one; in this way, the effect of blind insertion can be achieved, and the operation is convenient and simple.

The charging interface 17 can also be provided at other suitable positions of the atomizer, not limited to the bottom of the lower sleeve 22.

Preferably, since the atomized liquid contains sugar and the like, if the sugar is not fully burned on the heating element 44, carbon deposits will be generated on the heating element 44. Therefore, the control circuit board 16 is also connected to a carbon deposit removal switch, which can be set at the bottom of the lower sleeve 22 or on the side wall of the lower sleeve 22. When a lot of carbon deposits are accumulated on the heating element 44, the carbon deposit removal switch is triggered, and the control circuit board 16 controls the heating element 44 to continue to heat up. When the temperature rises to a certain temperature, the carbon deposits on the heating element 44 are gasified by high temperature, thereby completing the removal of carbon deposits.

For example, when the material of the heating element 44 is aluminum nitride, the control circuit board 16 can control the heating element 44 to heat up quickly (the temperature may be 500-800° C.) to gasify the carbon deposits at high temperature.

Preferably, the type of the carbon deposit removal switch can be a mechanical switch, an electrostatic touch switch, etc., which is manually triggered by humans, for example: pressing the carbon deposit removal switch for a few seconds, toggling the carbon deposit removal switch, touching the carbon deposit removal switch, etc. Of course, a Bluetooth module can also be provided on the control circuit board 16, and the interaction with electronic devices (smartphones, tablets, etc.) can be achieved through the Bluetooth module, and the carbon deposit removal function is triggered by a signal on the electronic device, for example: click on the carbon deposit removal option on the electronic device, and the control circuit board 16 controls the heating element 44 to continue to heat up after receiving the signal.
