Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a power module 10 in some embodiments, and fig. 2 is a schematic sectional view of a part of the power module 10 in some embodiments. The power supply assembly 10 may be employed in an atomising device, for example for powering an atomiser (not shown) in an atomising device, such that the atomiser is able to atomise an aerosol-generating substrate within the atomiser to produce an aerosol for absorption by a user. The power module 10 includes a battery 110, a switch button 120, a microphone 130, a microphone holder 140, and a housing 150 for accommodating the battery 110, the microphone 130, and the microphone holder 140. The battery 110 is used for supplying power to the atomizer, the switch button 120 is matched with the microphone 130 to control the power supply of the battery 110 to the atomizer, and the microphone holder 140 is used for fixing the microphone 130. The shell 150 is provided with an air inlet 1510, when the atomization device performs atomization operation, external air enters the shell 150 through the air inlet 1510, passes through the microphone seat 140 and then enters the atomizer to be mixed with aerosol, and accordingly the aerosol generated by the atomizer is taken out of the atomization device to be absorbed by a user.

Referring to fig. 1, 2 and 3 together, fig. 3 is a partially enlarged view of a region a in fig. 2. In which the dashed arrows shown in fig. 3 indicate the gas flow direction in the gas duct 1410. In some embodiments, the power module 10 has an air inlet channel 1610 and an air passage 1410 connected with each other, the air inlet channel 1610 is connected with the outside, the air passage 1410 is connected with the microphone 130, in other words, the air inlet channel 1610 and the air passage 1410 are connected with the microphone 130 and the outside of the power module 10. In some embodiments, the air passage 1410 includes a first passage 1420 and a second passage 1430 that communicate with each other, and the intake passage 1610 and the second passage 1420 are offset from each other in the extending direction of the intake passage 1610. The second channel 1420 is in communication with the microphone 130, in other words, the liquid in the second channel 1420 can flow to the microphone 130. The first passage 1420 is formed with a water blocking structure 1440, and the water blocking structure 1440 is capable of blocking the liquid in the first passage 1420 from flowing into the second passage 1430.

In the power module 10, the intake passage 1610 and the second passage 1430 are offset from each other in the extending direction of the intake passage 1610, that is, the gas or liquid in the intake passage 1610 must pass through the first passage 1420 to enter the second passage 1430. The first channel 1420 is provided with the water blocking structure 1440, when liquid entering the air channel 1410 from the outside flows to the first channel 1420 through the air inlet channel 1610, the liquid is blocked by the water blocking structure 1440 and cannot flow into the second channel 1430, so that the outside liquid can be prevented from flowing to the microphone 130 through the air channel 1410, the waterproof performance of the power supply module 10 is improved, and the risk of damage to the microphone 130 due to liquid inlet is reduced.

In some embodiments, the first channel 1420 and the second channel 1430 form a corner therebetween, in other words, the first channel 1420 and the second channel 1430 extend in different directions, which can further improve the waterproof performance of the power module 10. For example, the inner walls of the first channel 1420 are angled with respect to the inner walls of the second channel 1430. The first channel 1420 is away from the opening of the second channel 1430 for air intake, in other words, after the outside air enters the housing 150 through the air intake hole 1510, the outside air enters the microphone base 140 from the opening of the first channel 1420 away from the second channel 1430. The opening of the second channel 1430 away from the first channel 1420 corresponds to the position of the microphone 130, for example, in some embodiments, an end of the microphone base 140 corresponding to the opening of the second channel 1430 away from the first channel 1420 is sleeved on the microphone 130.

It should be noted that, in the present application, the inner wall of a certain channel is described and may be understood as the inner wall surface of the object defining the channel surrounding the channel, for example, the inner wall of the first channel 1420 may be understood as the inner wall surface of the first channel 1420 surrounding the microphone holder 140.

It can be understood that if the included angle between the inner wall of the first channel 1420 and the inner wall of the second channel 1430 is too large, the liquid blocking effect of the corner is reduced, thereby reducing the waterproof function of the microphone base 140; if the angle between the inner wall of the first channel 1420 and the inner wall of the second channel 1430 is too small, the corners will also obstruct the gas, thereby reducing the ventilation function of the microphone base 140. Thus, in some embodiments, the included angle between the inner wall of the first channel 1420 and the inner wall of the second channel 1430 is greater than or equal to 70 ° and less than or equal to 110 °. With such an arrangement, the microphone base 140 can not only realize an effective waterproof function, but also have a good ventilation function, thereby realizing a waterproof and ventilation effect. For example, in some embodiments, the angle between the inner wall of the first channel 1420 and the inner wall of the second channel 1430 is equal to 90 °, in other words, the directions of extension of the first channel 1420 and the second channel 1430 are perpendicular to each other.

Of course, the first channels 1420 and the second channels 1430 need not be regular circular channels, but may be any irregular channels, for example, the diameter of the first channels 1420 may increase or decrease in the direction of the airflow, and the angle between any point on the inner wall of the first channels 1420 and any point on the inner wall of the second channels 1430 may be between 70 ° and 110 °.

In other embodiments, the air channel 1410 may further include three, four or more channels connected to each other, and a corner is formed between any two adjacent channels, so as to achieve a better waterproof effect. However, the number of the channels cannot be too large, so as to avoid generating obvious obstruction to the gas and affecting the ventilation effect of the microphone base 140, for example, the number of the channels is less than or equal to three, so as to achieve good waterproof ventilation effect. The two channels are provided, so that the occupied space of the microphone base 140 can be reduced while a good waterproof and ventilating effect is achieved, and the miniaturization design of the power module 10 is facilitated.

The water retaining structure 1440 may be disposed in any suitable manner, for example, in some embodiments, the water retaining structure 1440 may be a protrusion extending into the first channel 1420. The retaining structure 1440 may be integrally formed with the microphone base 140 or may be a component fixedly connected to the inner wall of the microphone base 140. The position of the water blocking structure 1440 is not limited, as long as it can block the liquid from flowing to the microphone 130. For example, the dam 1440 may be disposed at a corner, or at any position of the first channel 1420 and the second channel 1430. Of course, in other embodiments, the water blocking structure 1440 may be another structure such as a throat embedded in the first channel 1420, as long as it can block the liquid from flowing to the microphone 130.

Further, in some embodiments, a water blocking structure 1440 is disposed at an end of the first channel 1420 adjacent to the second channel 1430. Therefore, when the liquid flows to the end of the first channel 1420, the water blocking structure 1440 can block the liquid from flowing into the second channel 1430, thereby fully utilizing the space of the first channel 1420 and blocking the liquid in the first channel 1420, which is beneficial to further improving the waterproof function of the microphone base 140. In addition, the water blocking structure 1440 may be a continuous structure disposed circumferentially around the inner wall surface of the first channel 1420, and as shown in fig. 3, the water blocking structure 1440 may be disposed only at a position where the inner wall surface of the first channel 1420 is closest to the microphone 130, as long as it can block liquid from entering the second channel 1430.

Further, the water blocking structure 1440 may be disposed at the lowest gravitational potential of the inner wall surface of the first channel 1420, in other words, in the embodiment shown in fig. 3, when the power module 10 is in use, the atomizer is generally located vertically above the power module 10, i.e. the gravitational potential of the atomizer is higher than that of the power module 10, so as to facilitate the user to absorb the aerosol sprayed from the atomizer. The gravitational potential energy of the microphone 130 is generally lower than that of the inner wall of the first channel 1420, in other words, when the liquid enters the first channel 1420, the gravitational potential energy is generally attached to the portion of the inner wall of the first channel 1420 closest to the microphone 130. Therefore, the water blocking structure 1440 is arranged at the position, closest to the microphone 130, of the inner wall surface of the first channel 1420, the structure of the water blocking structure 1440 does not occupy too much space of the first channel 1420, namely, the liquid can be effectively blocked from flowing into the second channel 1430 from the first channel 1420, so that the arrangement cost of the microphone seat 140 can be reduced, the water blocking structure 1440 does not obstruct airflow due to occupying too much space of the first channel 1420, and a good waterproof and ventilation effect is achieved. Of course, when the relative positions of the microphone 130, the bracket 160 and the microphone holder 140 in the power module 10 are changed, the position of the water blocking structure 1440 may also be adjusted accordingly, so that the water blocking structure 1440 is always located at the lowest gravitational potential energy position on the inner wall of the first channel 1420, and thus the water is effectively blocked from flowing from the first channel 1420 to the second channel 1430.

Referring also to fig. 1, 3 and 4, fig. 4 is a schematic diagram of some of the components of power module 10 in some embodiments. In some embodiments, the power module 10 further includes a bracket 160, the bracket 160 is received in the housing 150 and abuts the microphone base 140, and the bracket 160 can be used to limit the position of the switch button 120 and the microphone 130. Specifically, in some embodiments, one side of the microphone base 140 is slotted, and the bracket 160 abuts the slotted side of the microphone base 140 and defines a first channel 1420 with the microphone base 140. For example, a side of the microphone base 140 facing away from the battery 110 is slotted, and the bracket 160 partially abuts against a side of the microphone base 140 facing away from the battery 110 to define a first channel 1420 with the microphone base 140. The first channel 1420 can now be understood to be the space created by the slots of the microphone base 140. The second passage 1430 opens in the microphone base 140 and communicates with the first passage 1420, and the intake passage 1610 is provided in the holder 160. So set up, can carry out ingenious design to the spatial structure of miaow head seat 140 and support 160, form first passageway 1420 through the cooperation of support 160 with miaow head seat 140, save miaow head seat 140's occupation space, be favorable to atomizing device's miniaturization and portable design, first passageway 1420 is closer to support 160 more simultaneously, can communicate through support 160 and the inlet port 1510 of casing 150 more easily for power module 10's the more smooth and easy of admitting air.

Of course, in other embodiments, the first channel 1420 may be disposed in the microphone base 140, so that the occupied space of the microphone base 140 is relatively increased to have a sufficient structure to enclose the first channel 1420. It will be appreciated that the structure of the holder 160 is omitted from fig. 4 in order to embody the grooved structure of the microphone base 140.

In some embodiments, one end of the intake channel 1610 interfaces directly with the intake port 1510, or communicates with the intake port 1510 via other channel structures. The other end of the intake passage 1610 interfaces with an opening of the first passage 1420 remote from the second passage 1430, for example, as shown with reference to fig. 3, the intake passage 1610 opens at a position of the bracket 160 corresponding to the opening of the first passage 1420 remote from the second passage 1430.

Further, in some embodiments, a corner is also formed between the intake passage 1610 and the first passage 1420. Thus, when liquid flows through the intake channel 1610 to the corner of the intake channel 1610 and the first channel 1420, the corner can also act as a barrier to the liquid, thereby further improving the waterproof performance of the power module 10. In some embodiments, the included angle between the inner wall of the air inlet channel 1610 and the inner wall of the first channel 1420 is greater than or equal to 0 ° and less than or equal to 110 °, so that not only the effective waterproof effect can be achieved, but also the flowing of air is not hindered, which is beneficial to achieving the waterproof and ventilation effects. For example, in some embodiments, the inner wall of the intake passage 1610 forms an angle of 90 ° with the inner wall of the first passage 1420, in other words, the intake passage 1610 and the first passage 1420 extend in directions perpendicular to each other.

In some embodiments, the diameter of the intake passage 1610 is less than 1.4 cm. It will be appreciated that the passage of liquid through the orifice or passage is subject to a greater pressure than is normally the case. Specifically, assuming that the radius of the small hole or channel through which the liquid needs to pass is R and the surface tension of the liquid is a, the additional pressure generated when the liquid passes through the small hole or channel is P2 × a/R. It can thus be seen that the smaller the diameter of the orifice or passage, the greater the pressure that the liquid will overcome through the orifice or passage, in other words, the harder it is for the liquid to flow into the orifice or passage, the better the waterproofing properties of the orifice or passage. Because the capillary length of the water droplets is 1.4cm, the diameter of the air inlet channel 1610 is set to be smaller than 1.4cm, which increases the difficulty of the water droplets outside the atomizer entering the air inlet channel 1610, and improves the waterproof performance of the power module 10. For example, in some embodiments, the diameter of the intake passage 1610 is 1.2 cm.

Further, in some embodiments, the diameter of the intake passage 1610 is between 0.6mm and 0.8 mm. The diameter that sets up inlet channel 1610 is less than 0.8mm, has greatly promoted the degree of difficulty that external liquid got into inlet channel 1610 for external liquid is difficult to reach air flue 1410 through inlet channel 1610, thereby improves power module 10's waterproof performance. Specifically, when the diameter of the inlet channel 1610 is between 0.6mm and 0.8mm, the diameter of the inlet channel 1610 is extremely small with respect to the capillary length of the liquid, and the difficulty of the liquid entering the inlet channel 1610 is extremely large. Therefore, even if the atomizer is sprayed by water or in the rain, liquid is difficult to enter the air channel 1410 through the air inlet channel 1610, so that the microphone 130 is prevented from being damaged by the liquid, and the waterproof performance of the power module 10 is greatly improved. The diameter of the intake duct 1610 is set to be larger than 0.6mm, which can prevent the intake duct 1610 from being too small in diameter and obstructing the flow of gas, and thus the power module 10 can achieve a good waterproof and ventilation effect. For example, in some embodiments, the diameter of the inlet channel 1610 is 0.7mm, which provides good waterproof and venting.

Of course, the intake passage 1610 may be a regular circular passage or an irregularly shaped passage, for example, the diameter of the intake passage 1610 gradually increases, gradually decreases, or irregularly changes in the airflow direction. The maximum diameter of the inlet channel 1610 is less than 1.4cm, which also provides a barrier to liquid entering the air channel 1410, while the minimum diameter of the inlet channel 1610 is greater than 0.6mm, which does not affect the ventilation of the power module 10.

Referring to fig. 1, 3 and 4, the intake passage 1610 may also be defined by a duct structure provided in the bracket 160. For example, in some embodiments, the power module 10 further includes an air inlet tube 170, the air inlet tube 170 being disposed within the bracket 160, an inner wall of the air inlet tube 170 defining an air inlet passage 1610. It will be appreciated that the diameter of the inlet conduit 170 may be less than 1.4cm to act as a barrier to the ingress of liquid and to improve the waterproof effect of the power module 10. In some embodiments, the diameter of the air inlet tube 170 may be between 0.6mm and 0.8mm to achieve good waterproof and air-permeable properties. For example, in some embodiments, the diameter of the air inlet tube 170 is 0.7 mm.

It should be noted that, in the present application, the diameter of the pipe structure is described, for example, the diameter of the air inlet pipe 170 is described, and the diameter refers to the inner diameter of the air inlet pipe 170. Similarly, when the air inlet pipe 170 is a pipe structure having an irregular shape, the maximum diameter of the air inlet pipe 170 is less than 1.4cm, so as to achieve waterproof performance.

It is worth mentioning that an air inlet pipe 170 is provided in the bracket 160. The material of the intake duct 170 may be set, and the design of a part of the material improves the performance of the power module 10 and reduces the installation cost of the power module 10 as a whole. For example, a more solid substance may be used as the air inlet tube 170 to support the bracket 160; and waterproof materials can be adopted as the air inlet pipe 170, so that the air inlet pipe 170 is prevented from being damaged due to water vapor or external liquid carried by gas. In addition, the replaceable air inlet pipe 170 is adopted on the bracket 160 to limit the flowing space of the air flow, and the air inlet pipes 170 with different diameters can be replaced according to different application scenes, so that the application range of the power supply assembly 10 is widened, the structure of the bracket 160 does not need to be changed, and the setting cost of the bracket 160 can be further reduced. For example, when the power module 10 is used in an atomizer that requires a larger outlet flow, the larger diameter inlet tube 170 may be replaced to allow for a smoother airflow; when the power module 10 is applied to an atomizer which requires a high waterproof capability, the air inlet pipe 170 having a smaller diameter can be replaced, and the waterproof performance of the power module 10 can be improved.

It will be appreciated that in the embodiment shown in fig. 2, illustration of some components of the power module 10 is omitted, for example, the power module 10 may further include components such as a circuit board disposed on a side of the battery 110 facing away from the microphone 130. In the embodiment shown in fig. 1 and fig. 2, elements such as an atomizer of the atomizer are also omitted, and the arrangement of the omitted elements is not limited as long as the power supply assembly 10 can supply power to the atomizer to realize the atomizing function of the atomizer, and thus, the details are not repeated here.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
