Detailed Description

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1-3, in some embodiments, the present application provides an atomizing device 11, as shown in fig. 3, comprising a housing 100, an atomizing assembly 200, an air inlet channel 340, a sensing channel 350, and a sensing element 500. The atomizing assembly 200 is disposed in the housing 100, an atomizing chamber 250 for generating aerosol is formed through the atomizing assembly 200, the atomizing chamber 250 has an air outlet end 252 and an air inlet end 251 along a height direction H of the housing 100, and the air inlet end 251 is located below the air outlet end 252. The air inlet channel 340 is communicated with the air inlet end 251 to air the atomization cavity 250, one end of the sensing channel 350 is communicated with the air inlet end 251, and the sensing element 500 is arranged at the other end of the sensing channel 350. In one embodiment, the sensing channel 350 may be directly connected to the air inlet 251, i.e. the sensing channel 350 is directly connected to the air inlet 251. In another embodiment, one end of the sensing channel 350 may be in indirect communication with the air inlet end 251 through the air inlet channel 340, i.e. the sensing channel 350 shares part of the air channel with the air inlet channel 350, but the sensing channel 350 is not used for air inlet and air outlet. As shown in fig. 3 and 5, at least part of the sensing channel 350 is higher than the air inlet end 251 of the atomizing chamber 250 in the height direction H of the housing 100. The sensing element 500 is used to drive the atomizing assembly 200 to operate when a change in the airflow at the air inlet end 251 is detected, e.g., the sensing element 500 may be a microphone or the like.

When the user inhales, as shown in fig. 3, the above-mentioned atomizing device 11 may allow the external air to enter the air inlet end 251 of the atomizing chamber 250 through the air inlet channel 340, and then the aerosol generated in the atomizing chamber 250 is wrapped and sucked by the user to flow out from the air outlet end 252. In this process, when the user sucks, the airflow near the air inlet end 251 of the atomizing chamber 250 flows, that is, the airflow or the air pressure changes, that is, the negative pressure occurs at the end of the sensing channel 350 near the air inlet end 251, and the sensing element 500 at the other end of the sensing channel 350 can detect the airflow change to control the atomizing device 11 to start working. During use of the atomizing device 11, condensate may be generated in the atomizing chamber 250, and it will be appreciated that when the atomizing device 11 is vertically placed in the height direction H or held by a user in the height direction H, the condensate with a higher density in the atomizing chamber 250 will tend to flow to the lower air inlet end 251 under the action of gravity, and in another possible use scenario, the user may blow down from the air outlet end 252 into the atomizing chamber 250 during the sucking process, so that the condensate and other substances in the atomizing chamber 250 will tend to flow to the lower air inlet end 251. In this application, at least part of the sensing channel 350 is higher than the air inlet end 251 of the atomizing chamber 250, which means that the condensate or other substances flowing out of the air inlet end 251 of the atomizing chamber 250 cannot directly flow through the sensing channel 350 to touch the sensing element 500. In other words, the condensate and the like cannot overcome the gravity and turn over the sensing channel 350 higher than the air inlet end 251 of the atomizing cavity 250, so that the condensate and the like cannot flow from one end of the sensing channel 350 to the position of the sensing element 500 at the other end, and the contact between the sensing element 500 and the condensate and the like can be avoided as much as possible, so that the arrangement can avoid that the sensing element 500 is touched by mistake and started on one hand, and can avoid that the sensing element 500 is corroded on the other hand, thereby prolonging the service life of the sensing element 500 and preventing the detection sensitivity from being reduced or failed.

As shown in fig. 3 and 5, in some embodiments, at least a portion of the sensing channel 350 is higher than the end surface of the air inlet end 251 of the atomizing chamber 250 in the height direction H of the housing 100, and the end surface of the air inlet end 251 of the atomizing chamber 250 may be regarded as an interface a of the atomizing chamber 250 and the sensing channel 350.

As shown in fig. 3, the bracket assembly 300 is located between the atomizing assembly 200 and the bottom of the housing 100, and the sensing channel 350 and the air inlet channel 340 are formed in the bracket assembly 300.

The interface a between the straight hole 311 and the sensing channel 350 may be referred to as the interface a between the atomizing chamber 250 and the sensing channel 350, i.e., the end face of the air inlet end 251 of the atomizing chamber 250. As shown in fig. 3 and 5, in some embodiments, in the height direction H of the housing 100, a portion of the sensing channel 350 is bent in a "n" shape in the bracket assembly 300, and the sensing channel 350 located at the apex of the "n" shape is higher than the end surface of the air inlet end 251. Such a structural arrangement means that condensate cannot naturally flip over the "n" shaped partial sensing channel 350 against gravity and cannot flow to the location of the sensing element 500.

It should be noted that, in some embodiments, the air intake passage 340 may refer to a separate structure for conducting gas, such as a separate tubular structure, or the like, i.e., the air intake passage 340 may not be formed by the housing 100 or the bracket assembly 300. In other embodiments, the air intake passage 340 may also be defined by at least one of the bracket assembly 300 and the housing 100. Similarly, in some embodiments, the sensing channel 350 may also refer to a tubular structure having a separate structure, i.e., the sensing channel 350 may not be formed by the housing 100 or the bracket assembly 300. In other embodiments, the sensing channel 350 may also be defined by at least one of the bracket assembly 300 and the housing 100.

The bracket 330 is further provided with a gas passing hole 334 along the thickness direction, the sensing channel 350 comprises a first sensing channel 351 and a second sensing channel 352, the first cover 310 is covered with the gas passing hole 334 from the first surface 331, the first cover 310 is enclosed with the first surface 331 and the gas passing hole 334 to form the first sensing channel 351, the second cover 320 is arranged on the second surface 332 and covers the gas passing hole 334, the second cover 320 is enclosed with the second surface 332 to form a second sensing channel 352, one end of the second sensing channel 352 is communicated with the first sensing channel 351 through the gas passing hole 334, and the other end of the second sensing channel 352 is provided with a sensing element 500. As shown in fig. 5 and 6, in some embodiments, the first surface 331 of the bracket 330 is formed with a rib 3341 protruding around the edge of the air hole 334, and the rib 3341 protrudes into the first sensing channel 351 in the height direction H of the housing 100 so that the first sensing channel 351 is bent in a shape of "n" and the sensing channel 350 located at the vertex of the "n" is higher than the end surface of the air inlet end 251, which may be regarded as at least the end surface of the rib 3341 higher than the end surface of the air inlet end 251, and the end surface of the air inlet end 251 may be regarded as the interface a of the straight hole 311 and the first sensing channel 351. Such a structural arrangement means that condensate cannot in its natural state turn over the inverted U-shaped portion of the first sensing channel 351 against gravity and cannot flow to the location of the sensor element 500.

Referring to fig. 7, in some embodiments, a receiving groove 3321 is formed on the second surface 332 of the support 330, a gas passing hole 334 is formed in a wall of the receiving groove 3321, the second cover 320 is embedded in the receiving groove 3321 and encloses with the wall of the receiving groove 3321 to form a second sensing channel 352, the sensing element 500 is embedded in the second cover 320, the sensing element 500 has a first sensing surface 510 and a second sensing surface 520, the first sensing surface 510 is communicated with the second sensing channel 352, and the second sensing surface 520 is communicated with the outside. The first sensing surface 510 of the sensing element 500 communicates with the nebulizing chamber 250 through the sensing channel 350, and the first sensing surface 510 of the sensing element 500 can rapidly detect a change in air pressure when the user inhales.

Further, as shown in fig. 6, in some embodiments, the second cover 320 is provided with a sensing hole 322 in communication with the groove 321, and the sensing element 500 is embedded in the sensing hole 322; at least a portion of the second sensing channel 352 is lower than the first sensing surface 510 of the sensing element 500 in the height direction H of the housing 100.

Referring to fig. 3 and 5, in some embodiments, the inlet passage 340 is at least partially higher than the interface a of the atomizing chamber 250 and the inlet passage 340 in the height direction H of the housing 100. It will be appreciated that when the atomizing device 11 is vertically disposed in the height direction H or is held by a user in the height direction H, the condensate or the like (e.g., tobacco tar, water droplets) in the atomizing chamber 250 is easily flowed to the lower air inlet channel 340 by gravity, and in another possible use scenario, the user may blow air from the air outlet end 252 into the atomizing chamber 250 during the sucking process, so that the condensate or the like in the atomizing chamber 250 is also easily flowed to the lower air inlet channel 340. In this application, at least part of the air inlet channel 340 is higher than the interface a between the atomizing chamber 250 and the air inlet channel 340, which means that after condensate enters the air inlet channel 340 from the atomizing chamber 250, the condensate cannot flow out from the air inlet 333 against the gravity passing through the air inlet channel 340 at the higher end, i.e. such arrangement can avoid the occurrence of the situations of smoke and oil leakage, condensate leakage, etc. to the greatest extent, which is beneficial to improving the user experience.

Specifically, in the embodiment shown in fig. 3 and 5, in the height direction H of the housing 100, a portion of the air inlet passage 340 is bent into a "n" shape in the bracket assembly 300, and the air inlet passage 340 at the apex of the "n" shape is higher than the interface a of the atomizing chamber 250 and the air inlet passage 340. The arrangement means that the condensate cannot overcome gravity and turn over the inverted U-shaped part of the air inlet channel 340 in a natural state, so that the condensate cannot flow out of the air inlet 333, which is beneficial to improving user experience.

More specifically, in order to improve the connection reliability of the atomizing tube 240 and the first cover 310, the outer circumferential surface of the first cover 310 may be further provided with a limiting rib 312 as shown in fig. 6, and the first cover 310 may be made of a material having elasticity such as silica gel, so that when the oil storage tube 220 is sleeved on the outer circumferential surface of the first cover 310, the limiting rib 312 having a certain elasticity on the outer circumferential surface of the first cover 310 may be in interference fit with the inner side of the oil storage tube 220, thereby improving the connection reliability of the first cover 310 and the oil storage tube 220.

In addition, as shown in fig. 2 and 3, the present application further relates to an aerosol-generating device, which includes a power supply assembly 12 and the atomizing device 11 in any of the above embodiments, and the atomizing device 11 is electrically connected to the power supply assembly 12. The aerosol generating device may be a split-type electronic cigarette, that is, the atomizing device 11 may be a cartridge, the power supply device may be a cigarette rod with a power supply, and for a user, the atomizing device 11 and the power supply device may be simply disassembled and assembled to replace the atomizing device 11.

The aerosol-generating device may also be considered as a unitary e-cigarette, i.e. a disposable e-cigarette, and may be considered as both the atomizing assembly 200 and the power supply assembly 12 being built into the same housing 100. For example, as shown in fig. 1, 2 and 3, in some embodiments, the housing 100 may be divided into a top cover 110, a main body 120 and a bottom cover 130 having a suction nozzle 111, and the top cover 110, the main body 120 and the bottom cover 130 may be coupled and enclosed to form a cavity for accommodating the atomizing device 11 and the power supply assembly 12.

The aerosol-generating device may be provided with the atomizing device 11 of each of the embodiments described above, and therefore also includes at least the following advantages: in use, the atomizing device 11 is supplied with ambient air from the air inlet channel 340 into the air inlet end 251 of the atomizing chamber 250, and then the aerosol generated in the atomizing chamber 250 is entrained therein and flows out from the air outlet end 252 for inhalation by a user. When a user sucks, the airflow near the air inlet end 251 of the atomizing chamber 250 flows, that is, the airflow changes, that is, the negative pressure occurs at the end, close to the air inlet end 251, of the sensing channel 350, and the sensing element 500 at the other end of the sensing channel 350 can detect the airflow change to control the atomizing device 11 to start working. During use of the atomizing device 11, condensate may be generated in the atomizing chamber 250, and it will be appreciated that when the atomizing device 11 is vertically placed in the height direction H or held by a user in the height direction H, the condensate with a higher density in the atomizing chamber 250 will tend to flow to the lower air inlet end 251 under the action of gravity, and in another possible use scenario, the user may blow down from the air outlet end 252 into the atomizing chamber 250 during the sucking process, so that the condensate and other substances in the atomizing chamber 250 will tend to flow to the lower air inlet end 251. In this application, at least part of the sensing channel 350 is higher than the air inlet end 251 of the atomizing chamber 250, which means that the condensate or other substances flowing out of the air inlet end 251 of the atomizing chamber 250 cannot directly flow through the sensing channel 350 to touch the sensing element 500. In other words, the condensate and the like cannot overcome the gravity and turn over the sensing channel 350 higher than the air inlet end 251 of the atomizing cavity 250, so that the condensate and the like cannot flow from one end of the sensing channel 350 to the position of the sensing element 500 at the other end, and the contact between the sensing element 500 and the condensate and the like can be avoided as much as possible, so that the arrangement can avoid that the sensing element 500 is touched by mistake and started on one hand, and can avoid that the sensing element 500 is corroded on the other hand, thereby prolonging the service life of the sensing element 500 and preventing the detection sensitivity from being reduced or failed.
