Through the suction nozzle that can move up and down, when the user needs to inhale the atomized gas through the suction nozzle, take the suction nozzle out of the holding chamber, and the liquid in the liquid storage chamber flows into the atomizing unit through the liquid inlet channel. When the user inhales gas from the air intake cavity, the liquid stored in the atomizing unit is atomized into gas at high temperature. At this time, the first blocking member moves upward with the suction nozzle, and the atomized gas reaches the receiving cavity through the second air intake channel. The first air inlet channel at the bottom end of the suction nozzle is communicated with the accommodating cavity, so the atomized gas can enter the inside of the suction nozzle, and then be inhaled into the user's mouth through the opening at the top of the suction nozzle. After the device is used, the user puts the suction nozzle back into the accommodating chamber.

The droplets formed by the condensation of the gas in the accommodating cavity that is not inhaled by the user on the inner wall of the accommodating cavity can also be scraped off by the downward movement of the first blocking plate and the suction nozzle. The droplets then enter the atomization unit and the condensation chamber through the first air inlet channel and the return channel, respectively, to prevent the droplets adhering to the inner wall of the accommodating chamber from flowing back to the connection circuit, damaging other components and reducing the service life of the device. The first blocking member blocks the second air inlet passage, isolates the atomizing unit and the accommodating cavity, avoids the natural evaporation of the liquid stored in the atomizing unit through the second air inlet passage, saves the cost, and the user is more sensitive to the liquid. The inhalation operation is also very convenient.

2. Through the setting of the ejection device, the suction nozzle can be in two states of "ejection" and "retraction". When the suction nozzle is in the "retracted" state, the first elastic part of the outer wall of the suction nozzle is in a compressed state, and the upper end of the rotary switch It is overlapped with the push plate and the lower end is overlapped with the bump, which ensures that the first elastic member is located between the bump and the second limit part; and when the user needs to use the medical evaporative inhalation device, he only needs to apply downward pressure to the push plate. When the push plate moves downward, the overlapping state of the push plate and the rotary switch changes, which tends to tilt the rotary switch to one side. The elastic piece has an upward elastic force, which drives the suction nozzle to move upward until the bump is in contact with the first limit part. The user can use the part that the suction nozzle pops up to inhale the atomized liquid. After the suction is completed, the user only needs to The pop-up part of the suction nozzle is pressed down until the bump and the rotary switch are overlapped again, and the operation is more convenient.

The invention provides a medical evaporative inhalation device. The medical evaporative inhalation device mainly makes the atomized liquid easy for the user to inhale, making the user's intake of liquid medicine more convenient and easy to enter. The addiction caused by substances such as nicotine in traditional cigarettes has greatly reduced the harm to users.

In an embodiment of the present invention, as shown in FIG. 1 to FIG. 12 , it includes a housing 1, a suction nozzle 2, an atomizing unit 3 and a liquid storage chamber 4. The housing 1 is provided with a accommodating chamber 11, and the The suction nozzle 2 is arranged in the accommodating cavity 11, and the suction nozzle 2 can move up and down along the accommodating cavity 11. The bottom end of the suction nozzle 2 is provided with a first air intake channel 21, and the atomizing unit 3. Connect with the accommodating cavity 11 through the second air inlet channel 31, and the liquid storage cavity 4 communicates with the atomizing unit 3 through the liquid inlet channel 41;

The outer wall of the suction nozzle 2 is provided with a first blocking member 22 for blocking the second intake passage 31;

The lower end of the accommodating chamber 11 is provided with a condensation chamber 5, the accommodating chamber 11 is communicated with the condensation chamber 5 through the return passage 111, and the lower end of the condensation chamber 5 is provided with an air intake chamber 6, and the air intake chamber 6 It is connected with the atomizing unit 3 through the third air intake passage 61 .

Specifically, the medical evaporative inhalation device includes a suction nozzle 2 that can move up and down. When the user needs to inhale the atomized gas through the suction nozzle 2, the suction nozzle 2 can be taken out from the accommodating chamber 11, and the liquid in the liquid storage chamber 4 can be taken out. The liquid flows into the atomizing unit 3 through the liquid inlet channel 41. When the user inhales gas from the air inlet chamber 6, the liquid stored in the atomizing unit 3 is atomized into gas at high temperature due to the vacuum pressure applied by the user. The blocking member 22 moves upward with the suction nozzle 2 , and the atomized gas reaches the accommodating cavity 11 through the second air intake channel 31 and the third air intake channel 61 . Therefore, the atomized gas can enter the inside of the suction nozzle 2, and then be inhaled into the user's mouth through the opening 12 at the top of the suction nozzle 2. Since the interior of the accommodating cavity 11 is divided into a space where the first blocking member 22 is located In one area, and another area where the suction nozzle 2 is located, the circulation of the atomized liquid between the two areas is mainly realized through the airflow hole 114 .

After the device is used, the user can put the suction nozzle 2 back into the accommodating chamber 11. When the suction nozzle 2 moves downward, the unsucked steam at the bottom end of the suction nozzle 2 can be pushed into the condensation chamber 5, and the first blockage Both ends of the plate 22 and the outer side of the suction nozzle 2 are arranged close to the inner wall of the accommodating cavity 11 , and the atomized gas that is not inhaled by the user in the accommodating cavity 11 will condense into droplets and adhere to the inner wall of the accommodating cavity 11 . It can also be scraped off by the downward movement of the first blocking plate 22 and the suction nozzle 2. Since the bottom end of the accommodation chamber 11 is provided with a condensation chamber 5, the scraped droplets pass through the first air inlet channel 21 and the return channel. 111 enters the atomizing unit 3 and the condensation chamber 5 respectively, to prevent the droplets adhering to the inner wall of the accommodating cavity 11 from flowing back to the connection circuit, damaging other components and reducing the service life of the device. The second air inlet channel 31 is blocked, which isolates the atomizing unit 3 and the accommodating cavity 11, avoids the natural evaporation of the liquid stored in the atomizing unit 3 through the second air inlet channel 31, saves the cost, and the inhalation operation of the liquid by the user is avoided. It is also very convenient. The high temperature atomization of the atomization assembly 3 can be powered by the battery 115 in the casing 1. The activation of the atomization assembly 3 can be turned on by induction or a switch is installed on the casing 1, and the user can press the switch to turn on the atomization. operation of component 3.

Further, the housing 1 is also provided with an ejection device 7, a first limiting portion 112 and a second limiting portion 113, the outer wall of the suction nozzle 2 is provided with a bump 23, and the ejection device 7 includes a push-up device 7. The plate 71 , the rotary switch 72 and the first elastic member 73 , the push plate 71 and the rotary switch 72 are respectively hinged with the inner wall of the accommodating cavity 11 , and the first elastic member 73 is provided on the suction nozzle 2 . the outer wall, and the two ends of the first elastic member 73 are in contact with the protrusion 23 and the second limiting portion 113 respectively; when the suction nozzle 2 is located in the accommodating cavity 11, the rotation Two ends of the switch 72 are respectively overlapped with the push plate 71 and the protruding block 23 ; when the suction nozzle 2 pops up upward, the protruding block 23 abuts against the lower end of the first limiting portion 112 .

In this way, the ejection device 7 can make the suction nozzle 2 in two states of “ejection” and “retraction”. When the suction nozzle 2 is in the “retracted” state, the first elastic member 73 of the outer wall of the suction nozzle 2 is in a compressed state, and at this time it rotates The upper end of the switch 72 is overlapped with the push plate 71, and the lower end is overlapped with the bump 23, which restricts the first elastic member 73 of the outer wall of the suction nozzle 2 to be between the bump 23 and the second limit portion 113; When the evaporative inhalation device is used, it is only necessary to exert a downward force on the push plate 71. Since the push plate 71 and the rotary switch 72 are both hinged on the inner wall of the accommodating cavity 11, when the push plate 71 moves downward, the push plate 71 and the The overlapping state of the rotary switch 72 changes, which tends to tilt the rotary switch 72 to one side. When the rotary switch 72 is tilted to the point of disengagement from the overlapping state of the bump 23, due to the upward force of the first elastic member 73, the suction is driven. The nozzle 2 moves upwards until the bump 23 abuts against the first limiting portion 112 , and the user can use the ejected part of the nozzle 2 to inhale the atomized liquid. Press down until the bump 23 and the rotary switch 72 are overlapped again. A torsion spring (not shown) is also installed on the hinged connection shaft of the rotary switch 72 and the accommodating cavity 11, so that the The position is parallel to the suction nozzle 2, so that unless an external force is applied, the rotary switch 72 will overlap with the upper end of the projection 23 and keep the first elastic member 73 at the position where the first elastic member 73 is fixed, which is convenient to operate.

Further, one end of the condensation chamber 5 is provided with a second elastic member 51, the other end of which is abutted with a push switch 52, and the lower end of the push switch 52 is hinged with the housing 1, and the housing 1 is provided with an opening 12, and the condensation chamber 5 moves horizontally along the opening 12 through the second elastic member 51.

The condensation chamber 5 is set to a replaceable mode, and is stored and received at the lower end of the accommodating chamber 11 as condensed droplets that have been sucked. When the condensation chamber 5 is not taken out, the upper end of the push switch 52 is snapped into the groove at one end of the condensation chamber 5. and the condensing chamber 5 is further fixed by a torsion spring (not shown). Due to the limited accommodation volume of the condensing chamber 5, the liquid in the condensing chamber 5 needs to be discharged after a long period of use. When the push switch 52 is pressed inward, the contact state between the upper end of the push switch 52 and the condensation chamber 5 is changed, and one end of the condensation chamber 5 loses the force at the time of contact, and then the second elastic member 51 The condensation chamber 5 is ejected from the end of the opening 12. Since the lower end of the push switch 52 is hinged with the housing 1, the top of the push switch 52 can abut against the bottom end of the ejected condensation chamber 5, preventing the condensation chamber 5 After dropping from the opening 12, the user takes out the pop-up condensation chamber 5 and pours out the stored liquid, and then puts the condensation chamber 5 into the opening 12, and presses the condensation chamber 5 to make the second elastic member 51 in a compressed state again. Then turn the push switch 52 back until the upper end of the push switch 52 is snapped into the groove of the condensation chamber 5 again, and the cleaning of the condensation chamber 5 is completed. replace.

Further, the atomizing unit 3 includes an atomizing chamber 32, an atomizer 33 and a drawing member 34, the atomizer 33 is arranged in the atomizing chamber 32, and the drawing member 34 passes through a plurality of The connecting column 341 is slidably connected to the bottom end of the atomization chamber 32 .

That is, the atomizer 33 in this embodiment, as an important part of high-temperature atomized liquid, needs to be used every time the user inhales the atomized liquid, and the frequency of use is very high, so the atomizer 33 is used for a long period of time. 33 may fail due to various reasons. Usually, the atomizer 33 is set inside the atomization chamber 32 and cannot be taken out. After the atomizer 33 fails, the entire inhalation device fails, resulting in waste. Therefore, this setting is used as the atomization chamber 32. When the inner atomizer 33 fails, since the bottom of the atomization chamber 32 is slidably connected to the connecting column 341, specifically, the four connecting columns 341 are connected to the four holes at the bottom of the atomization chamber 32, and these holes are equipped with There is a slot and a protruding pin (not shown in the figure) on the connecting column 341, so that the pulling member 34 can slide along the hole position without falling off from the bottom end of the atomization chamber 32, and can also be clamped. In order to provide a better connection method, the puller 34 is taken out through the handle of the puller 34, and then a new atomizer 33 is placed inside the atomization chamber 32, and the puller 34 is removed. When 34 is closed, the atomizer 33 can be replaced, and the medical evaporative inhalation device can continue to be used. The atomizer 33 can be made of cotton wick or ceramic alloy.

Further, the air inlet cavity 6 is provided with an air inlet 62 , and the bottom end of the suction nozzle 2 is provided with a second blocking member 24 for blocking the air inlet 62 . The movement state of the second blocking member 24 is consistent with that of the suction nozzle 2 . When the suction nozzle 2 is located inside the accommodating cavity 11 , the second blocking member 24 blocks the air inlet 62 , so that the air inlet 62 evaporates during medical evaporation. The vacuum suction device is kept closed when not in use to prevent dust and moisture in the air from entering the device and causing contamination. When the user uses the suction nozzle 2, the suction nozzle 2 pops out from the accommodating cavity 11, and the second blocking member 24 follows with the suction nozzle 2. The upward movement opens the air inlet 62, which is convenient for the user to inhale gas from the air inlet 62 to drive the movement of the atomized liquid. After use, the suction nozzle 2 is retracted, and the second blocking member 24 blocks the air inlet 62 again. The operation is very simple and the design is more integrated.

Further, an air flow sensor 63 and a controller are also arranged in the air intake chamber 6, and the air flow sensor 63 is electrically connected to the atomizer 33 and the controller, respectively. It can be understood that the airflow sensor 63 is used to trigger the operation of the atomizer 33. Specifically, when air flows into the air intake chamber 6, the airflow sensor 63 senses the inflow of air and triggers the atomization through the controller (not shown). The opening of the device 33 will atomize the liquid stored in the atomizing chamber 32, which is more automatic than the way of opening the atomizing unit 3 by manually pressing the switch by the user.

Further, an annular cleaning layer 25 is sleeved on the outer wall of the suction nozzle 2 , and the cleaning layer 25 is located in the first limiting portion 112 . In this way, the function of the cleaning layer 25 is mainly to clean the saliva after the user uses the suction nozzle 2. The cleaning layer 25 can be made of cotton cloth or other materials. The outer wall of the suction nozzle 2, when the suction nozzle 2 moves up and down in the cleaning layer 25, the cleaning layer 25 located in the first limiting part 112 filters the saliva attached to the surface of the suction nozzle 2, and automatically cleans the surface of the suction nozzle 2.

Further, the outer wall of the atomizer 33 is provided with a connecting pin 331 , and the inner wall of the atomization chamber 32 is provided with a concave portion 321 cooperating with the connecting pin 331 . The atomizer 33 is arranged inside the atomization chamber 32, and is fixed by the connection between the connecting pin 331 and the concave part 321, so as to ensure that the atomizer 33 will not move freely in the atomization chamber 32, and prevent the atomizer 33 from being in the atomizer chamber 32. The collision with the atomizing chamber 32 during use prolongs the service life of the atomizing unit 3. In addition, as shown in FIG. 12, when there is airflow flowing into the airflow sensor 63, the pin of the battery 115 will be triggered to pass through the recess 321 to the connecting pin Electricity is applied at 331, and the heating part of the spiral coil in the atomizer 33 is heated. Through this connection, whenever the battery 115 is powered on, the atomizer 33 can atomize the liquid inside the atomization chamber 32.

Further, the condensation chamber 5 is provided with a sponge and a desiccant for absorbing condensate. Both the sponge and the desiccant function to absorb the condensed water dripping from the accommodating cavity 11 .

Further, the distance between the bottom end of the suction nozzle 2 and the bottom end of the accommodating cavity 11 is greater than or equal to the distance that the push plate 71 is pressed to make the rotary switch 72 rotate and press the protrusion 23 to move downward.

There is a distance between the bottom end of the suction nozzle 2 and the bottom end of the accommodating cavity 11. This distance needs to squeeze the push plate 71 downward when the suction nozzle 2 is ejected, so that the rotary switch 72 is rotated to force the bump 23 to move downward until the rotary switch 72 and the If the distance between the suction nozzle 2 and the accommodating cavity 11 is too small, when the rotary switch 72 squeezes the bump 23, the suction nozzle 2 will hit the bottom of the accommodating cavity 11, reducing medical evaporative inhalation. service life of the equipment. In addition, the length of the suction nozzle 2 to be ejected from the housing 1 needs to be consistent with the distance between the bottom of the bump 23 and the rotary switch 72. When the ejection distance of the suction nozzle 2 is too large, the suction nozzle 2 is not fully retracted. When the inside of the accommodating cavity 11 returns to the overlapping state of the rotary switch 72 and the bump 23, the suction nozzle 2 is placed outside the accommodating cavity 11, the design is unsightly and the suction nozzle 2 is easily polluted; when the ejection distance of the suction nozzle 2 If it is too small, it is necessary to press the suction nozzle 2 to a deep place inside the accommodating cavity 11, and the user's experience is not good.
