Referring to fig. 1 to 3, fig. 1 is a schematic exploded view of an atomizer according to an embodiment of the application; FIG. 2 is a cross-sectional view in the A-A direction of the atomizer of FIG. 1 in accordance with one embodiment of the present application;

FIG. 3 is a schematic view of the reservoir housing of FIG. 2; in the present embodiment, there is provided an atomizer 10 for atomizing an atomizing medium when energized to form an aerosol. The atomizing medium may be a medicinal liquid formed by dispersing a certain medicine in a liquid solvent, an oil added with aroma components, or any other liquid suitable for atomization, such as tobacco tar.

As shown in fig. 1 to 3, the atomizer 10 includes a cover 1, a liquid storage housing 2, an atomizing core 3, and a base 4. As shown in fig. 3, the liquid storage housing 2 is an integrally formed structure. The liquid storage housing 2 has a liquid storage chamber 21 and first and second openings 22a and 22b communicating with the liquid storage chamber 21. The liquid storage cavity 21 is used for storing or storing atomized media; the atomized medium is discharged through the first opening 22 a. The cover 1 is arranged on the second opening 22b of the liquid storage shell 2 in a covering manner and is used for covering and blocking the second opening 22b. Specifically, the cover body 1 and the liquid storage shell 2 can be clamped and fixed; the junction of lid 1 and stock solution casing 2 can adopt first sealing washer 7a to prevent that the atomizing medium in the stock solution chamber 21 from revealing from the junction of lid 1 and stock solution casing 2. Of course, the cover 1 and the liquid storage shell 2 can also be connected by adopting an ultrasonic welding process, so that the cover 1 and the liquid storage shell 2 are welded together to play a role of sealing. Wherein, directly locate the second opening 22b of stock solution casing 2 with lid 1 lid, not only the equipment is simple and convenient, has promoted production efficiency, and the sealed effect of stock solution chamber 21 is better, has reduced the weeping risk, simultaneously can also reduce cost.

Referring to fig. 2, the atomizing core 3 has a liquid absorbing surface and an atomizing surface opposite to each other, is embedded in the liquid storage housing 2, and seals the first opening 22a for atomizing an atomizing medium to form aerosol. Specifically, the atomizing core 3 includes a porous substrate and a heating element disposed on the porous substrate, the porous substrate is used for guiding an atomizing medium to the heating element, and the heating element is used for heating to atomize the atomizing medium when being electrified. Wherein, the atomizing face of atomizing core 3 is formed to the one side that the heat-generating body is located, and the porous base member deviates from the liquid level of atomizing core 3 of one side formation of heat-generating body.

The atomization core 3 is directly embedded in the liquid storage shell 2 so as to be directly communicated with the liquid storage cavity 21; need not to establish other supports that are used for supporting atomizing core 3 in addition, atomizing core 3 does not have direct equipment relation with other parts except stock solution casing 2, has avoided the tolerance that the equipment between atomizing core 3 and other parts produced to lead to the fact the influence to the sealed effect of atomizing core 3 place position, has promoted the sealed effect of atomizer 10, has reduced weeping risk and equipment precision requirement, simultaneously can also reduce cost. In addition, the atomizing core 3 can also function to seal the first opening 22 a.

In one embodiment, referring to fig. 2 and 3, along the axial direction Y of the reservoir housing 2, the atomizing wick 3 is located directly below the reservoir 21 and is in direct communication with the reservoir 21.

Specifically, as shown in fig. 3, the reservoir housing 2 includes a reservoir portion 2a and a flange portion 2b in the axial direction Y thereof. The reservoir 2a defines a reservoir chamber 21 and a second opening 22b. The flange portion 2b defines a lower liquid passage 23 and a first accommodation chamber 24; the lower liquid channel 23 is directly communicated with the liquid storage cavity 21, and the first accommodating cavity 24 is positioned at one side of the lower liquid channel 23 away from the liquid storage cavity 21, is directly communicated with the lower liquid channel 23, and defines a first opening 22a; the liquid-absorbing surface of the atomizing core 3 faces the liquid-down channel 23 and is embedded in the first accommodating chamber 24. Thus, the atomization core 3 and the liquid storage shell 2 can be fixed, the first opening 22a can be blocked by the atomization core 3, and the liquid leakage risk of the liquid storage shell 2 is reduced. In a specific embodiment, the atomizing core 3 is sleeved in the first accommodating cavity 24 and abuts against the side wall of the first accommodating cavity 24.

The liquid storage portion 2a is a hollow shell, the hollow structure of the liquid storage portion 2a forms a liquid storage cavity 21, and an orifice of the liquid storage cavity 21 serves as a second opening 22b. The lower liquid channel 23 is provided with a liquid inlet and a liquid outlet which are opposite, the liquid inlet is communicated with the bottom wall of the liquid storage cavity 21, and the ratio of the cross-sectional area of the liquid inlet to the cross-sectional area of the bottom wall of the liquid storage cavity 21 is not less than 80%; such as 80%, 85%, 90% or 95%; in this way, the drainage rate can be increased. Further, the ratio of the cross-sectional area of the liquid outlet of the lower liquid passage 23 to the cross-sectional area of the bottom wall of the liquid storage chamber 21 is not less than 70%, such as 75%, 80%, 85% or 90%; therefore, compared with the scheme that the cross section area of the existing liquid discharging channel and the cross section area of the liquid storage cavity 21 are about 5% -10%, more liquid absorbing surfaces of the atomizing core 3 can be exposed through the liquid discharging channel 23, so that the liquid absorbing surfaces are in direct contact with atomizing media in the liquid storage cavity 21, namely, no shielding object exists between the liquid absorbing surface of the atomizing core 3 and the liquid storage cavity 21, bubbles generated when the liquid absorbing surface absorbs the atomizing media can be effectively prevented from being trapped by the shielding object, and the problem that the atomizing media cannot be quickly transferred to the atomizing surfaces occurs.

Specifically, the cross-sectional area of the lower liquid passage 23 gradually decreases in a direction away from the liquid reservoir 21. Therefore, a certain flow guiding effect can be achieved, and the liquid discharging is facilitated; and the bubbles in the liquid discharging channel 23 are beneficial to rising into the liquid storage cavity 21, so that the pressure release is smoother. In particular, the downcomer channel 23 may be in particular an inverted cone-shaped hole.

In a specific embodiment, as shown in fig. 2 and 3, the lower liquid channel 23 is communicated with the bottom wall of the first accommodating cavity 24, and the atomizer 10 further comprises a first sealing pad 5a, wherein the first sealing pad 5a is arranged between the liquid suction surface of the atomizing core 3 and the bottom wall of the first accommodating cavity 24, and is used for sealing a gap between the atomizing core 3 and the first accommodating cavity 24, so as to prevent the atomized medium in the lower liquid channel 23 from leaking out through the gap between the atomizing core 3 and the first accommodating cavity 24. Wherein, the liquid suction surface of the atomizing core 3 is exposed to the liquid discharging channel 23 through the first gasket 5 a. The sealing ring or the sealing gasket related to the application can be of elastic structures such as silica gel or rubber.

With reference to fig. 2, the cross-sectional area of the liquid suction surface of the atomizing core 3 is the same as the cross-sectional area of the first accommodation chamber 24; referring to fig. 3, the cross-sectional area of the first accommodation chamber 24 is larger than the cross-sectional area of the one end port (i.e., the liquid outlet) of the lower liquid passage 23 toward the first accommodation chamber 24; and along the axial direction Y of the liquid storage housing 2, the orthographic projection of the liquid outlet of the liquid lower channel 23 falls in the first accommodating cavity 24. So, when atomizing core 3 inlays in first chamber 24 that holds, the orthographic projection of atomizing core 3 on liquid storage shell 2 along the axial direction Y of liquid storage shell 2 will cover the liquid outlet of liquid channel 23 down, compare in atomizing core 3 along the axial direction Y of liquid storage shell 2 on liquid storage shell 2 with the liquid outlet coincidence of liquid channel 23 down or fall the scheme in the liquid outlet of liquid channel 23 down, can reduce the risk that atomizing medium directly revealed from the lateral wall of atomizing core 3 through the liquid outlet of liquid channel 23 down.

Specifically, the ratio of the cross-sectional area of the liquid outlet of the lower liquid passage 23 to the cross-sectional area of the first accommodation chamber 24 is not less than 90%; for example, 90%, or 93% or 95%, etc. That is, the ratio of the cross-sectional area of the orthographic projection of the liquid outlet of the lower liquid passage 23 on the atomizing core 3 to the area of the entire liquid suction surface of the atomizing core 3 is not less than 90% along the axial direction Y of the liquid storage housing 2. Therefore, not less than 90% of the liquid absorbing surface of the atomization core 3 can be exposed out of the lower liquid channel 23, so that more liquid absorbing surfaces are directly communicated with the liquid storage cavity 21 and are directly contacted with the atomization medium in the liquid storage cavity 21, no shielding object exists between the liquid absorbing surface of the atomization core 3 and the liquid storage cavity 21, and the problem that bubbles generated when the liquid absorbing surface absorbs the atomization medium are trapped by the shielding object and the atomization medium cannot be quickly transferred to the atomization surface can be effectively prevented.

In one embodiment, with continued reference to fig. 2 and 3, the reservoir housing 2 further defines an outlet channel 25 and a second receiving chamber 26. The cover body 1 is provided with an air outlet pipeline 11 at the position corresponding to the air outlet channel 25, the air outlet pipeline 11 is communicated with the air outlet channel 25, and aerosol formed by atomizing the atomizing core 3 flows out sequentially through the air outlet channel 25 and the air outlet pipeline 11. In the specific embodiment, the air outlet channel 25 is located at one side of the first accommodating cavity 24 along the radial direction X of the liquid storage cavity 21; i.e. the air outlet channel 25 is located at one side of the atomizing core 3; compared with the scheme that the air outlet channel 25 surrounds the circumferential direction of the atomizing core 3, the air flow in the air outlet channel 25 positioned at one side of the atomizing core 3 takes away less heat on the atomizing core 3, so that the heat loss of the atomizing core 3 is reduced, and the atomizing efficiency of the atomizing core 3 is improved.

Specifically, the bottom wall of the reservoir 21 has an extension portion 2c, the extension portion 2c extends in a direction away from the flange portion 2b, and the air outlet passage 25 penetrates the extension portion 2c and the flange portion 2b in the axial direction Y of the reservoir housing 2. In a specific embodiment, the atomizer 10 further includes a second sealing pad 5b, where the second sealing pad 5b is disposed between the air outlet channel 25 and the cover 1, and is used to seal the junction between the air outlet channel 25 and the air outlet pipeline 11 to prevent the aerosol from being exposed.

The second accommodating cavity 26 is communicated with the air outlet channel 25 and is positioned on one side of the air outlet channel 25 away from the cover body 1, and aerosol formed by atomization of the atomization core 3 enters the air outlet channel 25 through the second accommodating cavity 26. Specifically, the second accommodating chamber 26 is located on one side of the first accommodating chamber 24 in the radial direction X of the liquid storage housing 2, and the second accommodating chamber 26 is isolated from the first accommodating chamber 24. The mutually isolated means that the side walls of the two accommodating cavities are not provided with through holes, and the through holes extend from the inner wall surface of one accommodating cavity to the inner wall surface of the other accommodating cavity, that is to say, the two accommodating cavities are not mutually communicated; if the openings of the two accommodating chambers are sealed, the two accommodating chambers cannot exchange gas, liquid or the like.

By isolating the first accommodating cavity 24 from the second accommodating cavity 26, the atomized medium in the first accommodating cavity 24 can be prevented from leaking into the second accommodating cavity 26, and the risk of liquid leakage and direct suction of the atomized medium by a user is reduced. Meanwhile, the air flow passing through the second accommodating cavity 26 cannot pass through the first accommodating cavity 24 again, so that when the air flow passes through the second accommodating cavity 26, the heat of the atomizing core 3 can be taken away by the air flow, and the atomizing efficiency of the atomizing core 3 can be improved.

Specifically, the cross-sectional area of the second accommodation chamber 26 is larger than the cross-sectional area of the one end port of the air outlet passage 25 toward the second accommodation chamber 26. In this way, the aerosol condensate in the second accommodating chamber 26 can be reduced from entering the air outlet channel 25, which affects the occurrence of the suction taste problem.

Specifically, the liquid storage chamber 21, the first accommodating chamber 24, the second accommodating chamber 26, and the air outlet channel 25 may be equal-diameter chambers, and the radial dimensions of the equal-diameter chambers at each position along the axial direction Y of the liquid storage housing 2 are the same.

Referring to fig. 2, the base 4 has an air inlet hole 41, and the air inlet hole 41 communicates with the outside air. The liquid storage shell 2 is specifically arranged on the base 4 and is matched with the base 4 to form a containing cavity 40; the air inlet holes 41 and the air outlet channels 25 are respectively communicated with the accommodating cavity 40. During the suction process, the external air enters the accommodating cavity 40 through the air inlet holes 41 and carries the aerosol generated by the atomizing surface out through the air outlet channel 25. In a specific embodiment, the atomizer 10 further includes a second sealing ring 7b, where the second sealing ring 7b is disposed at the connection between the base 4 and the liquid storage housing 2, for sealing the accommodating cavity 40.

Specifically, as shown in fig. 2, the orthographic projection of the air inlet hole 41 is located on the atomizing surface of the atomizing core 3 along the axial direction Y of the liquid storage housing 2. In this way, the air flow entering through the air inlet hole 41 directly impacts the atomization surface, so that the aerosol generated on the atomization surface is taken away by the air flow quickly, and the influence of the aerosol on the atomization effect and the atomization efficiency caused by the accumulation of the aerosol on the atomization surface is avoided.

Referring to fig. 1 and 2, in one particular embodiment, the base 4 has a receiving slot 42, the receiving slot 42 having opposed bottom walls and notches; the liquid storage shell 2 is partially sleeved on the notch of the accommodating groove 42 and is matched with the accommodating groove 42 to form the accommodating cavity 40. The air inlet hole 41 is specifically formed on the bottom wall of the accommodating groove 42, and the air inlet hole 41 extends from the bottom wall of the accommodating groove 42 toward the direction of the notch, that is, along the axial direction Y of the liquid storage housing 2, the port of one end of the air inlet hole 41 facing away from the bottom wall of the accommodating groove 42 is higher than the bottom wall of the accommodating groove 42. In this way, the probability of aerosol condensate or atomized substrate within the receiving cavity 40 leaking out of the air inlet aperture 41 may be reduced.

In some embodiments, referring to fig. 4 and 5, fig. 4 is a cross-sectional view of the atomizer 10 of fig. 1 in A-A direction provided by another embodiment of the present application; fig. 5 is a schematic structural diagram of a condensation structure 6 according to an embodiment of the present application. The atomizer 10 further comprises a condensation structure 6, wherein the condensation structure 6 is arranged in the accommodating cavity 40 and is used for reducing the temperature of aerosol formed by atomization so as to avoid the condition that a mouth or a liquid storage shell 2 scalds hands. Specifically, the condensation structure 6 is spaced from the atomizing core 3 and the air outlet channel 25, and the air flow entering the air inlet hole 41 impacts the atomizing surface and carries the aerosol formed by atomizing the atomizing surface, enters the air outlet channel 25 through the gap between the condensation structure 6 and the atomizing core 3, and flows out of the atomizer 10.

In this embodiment, the orthographic projection of the outlet channel 25 onto the base 4 falls within the orthographic projection of the condensation structure 6 onto the base 4 along the axial direction Y of the reservoir housing 2. Thus, the air outlet path of the aerosol can be shortened, so that the generation amount of aerosol condensate is reduced; and the condensate in the air outlet channel 25 can directly flow into the condensation structure 6 under the action of gravity, so that the probability of leakage from the air inlet hole 41 due to more aerosol condensate effusion in the accommodating cavity 40 is reduced.

Specifically, referring to fig. 4 and 5, along the radial direction X of the liquid storage housing 2, the condensation structure 6 and the air outlet channel 25 are located on the same side of the liquid storage cavity 21; and the side surface of the condensation structure 6 facing the air intake hole 41 includes an inclined surface 61, the inclined surface 61 being inclined in a direction facing away from the air intake hole 41; and the orthographic projection of the air outlet channel 25 falls on the inclined surface 61 in the axial direction Y of the reservoir housing 2. Thus, the inclined surface 61 can be utilized to guide the air flow; and the air flow is discharged from the air outlet channel 25 through the inclined surface 61, large particle droplets in the aerosol can be absorbed by the inclined surface 61, and at the same time, condensate is stored and locked, so that the condensate is prevented from being sucked into the oral cavity of the user.

Specifically, the condensation structure 6 includes a vertical surface and an inclined surface 61 along the thickness direction Y of the condensation structure 6 toward one side surface of the air intake hole 41, and the inclined surface 61 is located at one end of the vertical surface near the atomizing core 3 and extends from the vertical surface toward a direction away from the air intake hole 41.

Specifically, the outer wall surface of the condensation structure 6 abuts against and cooperates with the inner wall surface of the side wall of the accommodating groove 42 to form a plurality of condensation grooves 62, and the condensation grooves 62 are arranged at intervals along the axial direction Y of the liquid storage shell 2 and are used for storing aerosol condensate in the accommodating cavity 40 to prevent liquid leakage. Specifically, in connection with fig. 5, each condensation groove 62 has a first notch 62a and a second notch 62b opposite to each other, and the openings of the first notch 62a and the second notch 62b are oriented perpendicularly to the axial direction Y of the liquid storage housing 2, so as to avoid the problem that condensate in the condensation groove 62 is drained to the air outlet channel 25 and sucked by a user.

In one embodiment, as shown in fig. 5, a plurality of condensation grooves 62 are formed on the outer wall surface of the condensation structure 6 and are spaced apart in the thickness direction of the condensation structure 6. The first notch 62a and the second notch 62b of the condensation groove 62 are formed on a side surface of the condensation structure 6 facing the intake hole 41. Specifically, the condensation groove 62 extends in the circumferential direction of the condensation structure 6; in this way, the condensate may be blocked from creeping along the outlet channel 25.

Wherein the condensing structure 6 comprises at least one of liquid-absorbing cotton, cloth and ceramic. It will be appreciated that if the condensation structure 6 is a liquid suction surface or a cloth, it may be selected not to provide the condensation tank 62 because it has a certain liquid storage function. If the condensation structure 6 is ceramic, it is preferable that a plurality of condensation grooves 62 are formed on the condensation structure 6.

In the related art, in order to maintain the air pressure balance inside and outside the liquid storage cavity 21, a pressure release channel is usually provided on the outer side wall of the bracket, but in the assembly process, due to too many related parts, the accumulated tolerance generated by the assembly can cause poor consistency of the pressure release effect, the air pressure difference inside and outside the liquid storage cavity cannot be released in time, and the atomization medium cannot be smoothly introduced into the atomization core 3, so that the atomization core 3 is easy to generate burnt smell.

For this reason, in some embodiments of the present application, referring to fig. 3, the inner wall surface of the liquid storage housing 2 cooperates with the side wall surface of the atomizing core 3 to form a pressure relief channel, one end of which communicates with the external air, and the other end of which communicates with the liquid storage cavity 21 through the liquid discharging channel 23. Thus, the pressure can be relieved through the pressure relief channel, so that the air pressure balance inside and outside the liquid storage cavity 21 is realized, and the liquid discharging is facilitated; the side wall surface of the atomization core 3 is also used as the side wall of the pressure relief channel, so that when an atomization medium exists in the pressure relief channel, the atomization medium in the pressure relief channel can be absorbed by the atomization core 3 and atomized in the working state of the atomization core 3, the risk that the pressure relief channel cannot be relieved due to blockage caused by entering the atomization medium is effectively reduced, the external gas is ensured to be quickly supplemented into the liquid storage cavity 21, and the air pressure balance inside and outside the liquid storage cavity 21 is maintained; and simultaneously improves the utilization rate of the atomized medium. Meanwhile, compared with the scheme that a pressure release channel which is directly communicated with the liquid storage cavity 21 is formed in the support, the pressure release channel is only arranged corresponding to the atomization core 3, and the thickness of the atomization core 3 is lower and is about 1mm-5mm, so that the travel distance of the pressure release channel is shorter, the pressure release speed is faster, and the cost is lower.

In one embodiment, as shown in fig. 3, the inner wall surface of the first accommodating chamber 24 has a pressure relief groove 241 thereon; the pressure relief groove 241 extends from an end port of the first accommodation chamber 24 facing away from the lower liquid passage 23 to an end port of the first accommodation chamber 24 communicating with the lower liquid passage 23 to communicate with the lower liquid passage 23; the side wall surface of the atomizing core 3 is abutted with the side wall of the first accommodating cavity 24; the liquid suction surface of the atomizing core 3 is abutted against the bottom wall of the first accommodating cavity 24 so as to cover the pressure relief groove 241 and form a pressure relief channel in cooperation with the pressure relief groove 241. Thus, compared with the scheme of arranging the pressure relief groove 241 on the outer wall surface of the atomizing core 3, the problem of damaging the atomizing core 3 and affecting the liquid absorption and atomizing performance of the atomizing core 3 can be avoided. Meanwhile, the pressure relief groove 241 and the liquid storage shell 2 are integrally formed, so that the cost is low; and the pressure release groove 241 is directly formed on the liquid storage shell 2, so that the pressure release groove is more stable and better in consistency, and interference caused by the fit tolerance of other structural members is avoided.

Specifically, as shown in fig. 7, the reservoir housing 2 includes a reservoir portion 2a and a flange portion 2b in an axial direction Y thereof; the liquid storage part 2a defines a liquid storage cavity 21; the flange portion 2b defines a drain passage 23; the lower liquid channel 23 is directly communicated with the liquid storage cavity 21; the first opening 22a is formed in the side wall of the lower liquid channel 23; the atomizing core 3 is specifically embedded in the first opening 22 a.

Compared with the scheme that the atomizing core 3 is arranged right below the liquid storage cavity 21 in the embodiment, the arrangement not only realizes that the atomizing core 3 is directly embedded in the liquid storage shell 2 and is directly communicated with the liquid storage cavity 21, but also does not need to be additionally provided with other brackets for supporting the atomizing core 3; and can reduce and absorb more atomizing medium on the atomizing core 3, avoid atomizing core 3 atomizing not in time to lead to the risk that the atomizing medium overflows to the holding chamber 40 and takes place the weeping. Meanwhile, the side wall of the liquid discharging channel 23 is opened, the atomizing core 3 is embedded into the opening of the side wall, the production process is simple, and the cost is low.

In this embodiment, the lower liquid passage 23 may be an equal diameter hole in the axial direction Y of the liquid reservoir housing 2. The ratio of the width w1 of the first opening 22a in the axial direction Y of the reservoir housing 2 to the width w2 of the flange portion 2b in the axial direction Y of the reservoir housing 2 is not less than 80%; such as 85%, or 90%, or 95%, etc.

Specifically, as shown in fig. 6, the atomizing surface of the atomizing core 3 is disposed facing away from the lower liquid passage 23, and the plane on which the atomizing surface is disposed is parallel to the axial direction Y of the liquid storage housing 2. So, when there is more atomizing medium on the atomizing face, atomizing medium can remove towards base 4 under self gravity effect, like this, can not deposit too much atomizing medium on the atomizing face of atomizing core 3, and the atomization effect is better. Of course, the plane of the atomizing surface and the axial direction Y of the liquid storage shell 2 may also be inclined at a preset angle α; the preset angle alpha is more than or equal to 60 degrees and less than or equal to 90 degrees; for example, the preset angle is 70 °, or 80 °, or 85 °, or the like.

Wherein the flange portion 2b further defines a third receiving chamber 27; the third accommodating cavity 27 is located at one side of the lower liquid channel 23 along the radial direction X of the liquid storage shell 2, and shares a common side wall m with the lower liquid channel 23, and the first opening 22a is specifically opened at the common side wall m and communicates the lower liquid channel 23 with the third accommodating cavity 27; the air outlet channel 25 is in particular in communication with a third accommodation chamber 27. In this embodiment, as shown in fig. 6, the air intake hole 41 may be provided on the bottom wall of the base 4 and extend toward the reservoir housing 2 as in the atomizer 10 provided in the above embodiment; the airflow entering the air inlet hole 41 flows from the side of the atomizing surface facing the air inlet hole 41 to the side of the atomizing surface facing the air outlet channel 25, so that the aerosol formed by atomizing the atomizing surface is more fully taken away, and the utilization rate of the aerosol is provided.

Of course, in other embodiments, the orthographic projection of the air inlet hole 41 along the radial direction X of the liquid storage housing 2 may also fall on the atomizing core 3. Compared with the scheme that the air inlet holes 41 are formed on the bottom wall of the base 4, the risk that condensate in the accommodating cavity 40 leaks out through the air inlet holes 41 is reduced, more condensate can be stored in the accommodating cavity 40, and the risk of liquid leakage is further reduced. Specifically, the air inlet 41 may be formed on a side wall of the liquid storage housing 2, and along a radial direction X of the liquid storage housing 2, an orthographic projection of the air inlet 41 falls in the first opening 22 a.
