As shown in fig. 5, 11, and 12, further, in the present embodiment, the power supply assembly may further include a first sealing member 80, and the first sealing member 80 may be engaged with the bracket 20 and may be disposed corresponding to the airflow sensing device 50. Specifically, in the present embodiment, the first sealing element 80 can be disposed at the opening 204 of the second receiving cavity 202 of the bracket 20 and pressed against the circuit board 40. In the present embodiment, the first sealing member 80 may be a silicone member, but it is understood that in other embodiments, the first sealing member 80 may not be limited to a silicone member. In this embodiment, the first sealing element 80 may have a square cross-section, and the shape and size thereof may be adapted to the second receiving cavity 202.

Further, in the present embodiment, the first sealing element 80 includes an elastic body 81, and the shape and size of the elastic body 81 can be adapted to the second accommodating cavity 202. In this embodiment, the first seal 80 may be provided with a first opening 82, a second opening 83, and a fluid passage 84 communicating the first opening 82 and the second opening 83. The first opening 82 can be located on the elastic body 81 and disposed near the second end wall 24, and is communicated with the air inlet 241 on the second end wall 24, and the first opening 82 can provide air flow to flow out and into the air inlet 241 of the second end wall 24, and provide condensed liquid to flow in if condensed liquid exists. The second opening 83 can be disposed on the elastic body 81 and near the blocking wall 25. The second opening 83 can communicate with the airflow hole 401 on the circuit board 40, and further communicate with the airflow sensing device 50. In this embodiment, the cross-sectional area of the second opening 83 may be larger than the cross-sectional area of the airflow hole 401 on the circuit board 40, so that the normal operation of the airflow sensing device 50 is not affected even when the installation is slightly misaligned. Specifically, the second opening 83 and the airflow hole 401 of the wiring board 40 may be circular holes, and the aperture of the second opening 83 may be larger than the aperture of the airflow hole 401 of the wiring board 40. The fluid passage 84 may communicate the first opening 82 and the second opening 83. When the user sucks, the air can pass through the air flow sensing device 50, enter the second opening from the air flow hole 401 of the circuit board 40, and then pass through the fluid channel to be output from the second opening 83 to the air inlet hole 241 of the second end wall 24, so that the air flow sensing device 50 is in a negative pressure state. Condensate can be output from the inlet aperture 241 into the first opening 82 and into the fluid passage 84, where it can be stored in the fluid passage 84. In this embodiment, the fluid channel may be designed such that the path of the condensate flowing from the first opening 82 to the second opening 83 through the fluid channel 84 is longer than the path of the airflow flowing from the second opening 83 to the first opening 82 through the fluid channel 84, that is, the fluid channel has different flow resistances for different flow directions, so that the airflow can normally flow to the first opening 82 to achieve normal operation of the airflow sensing device 50, and the condensate is difficult to flow to the second opening 83, so that the condensate can be prevented from corroding the airflow sensing device 50 and the circuit board 40.

Further, in this embodiment, the fluid path 84 includes a main path 841 and at least one return path 842. The main channel 841 can be centrally disposed and can be linearly disposed, with one end communicating with the first opening 82 and the other end communicating with the second opening 83. Of course, it is understood that in other embodiments, the main channel 841 is not limited to being centrally disposed and not limited to being linearly distributed. The number of the backflow passages 842 may be multiple, and a plurality of backflow passages 842 may be disposed side by side on two opposite sides of the main passage 841. Of course, it is understood that in other embodiments, there may be only one return passage 842. The return passage 842 can be communicated with the main passage 841 to increase the fluid path, thereby reducing the reflux of the condensate to the circuit board 40 and preventing the condensate from polluting the circuit board 40 and the gas flow reaction device 50. In this embodiment, the backflow channel 842 may be disposed obliquely toward the second opening 83, and may form a set included angle with the main channel 841, in this embodiment, the set included angle may be an acute angle, specifically, the set included angle may be 30 to 60 degrees, and preferably 45 degrees, and the configuration space may be optimized by disposing the backflow channel 842 obliquely with respect to the longitudinal axis of the main channel 841 in an acute angle.

Further, in the present embodiment, the return passage 842 includes a flow portion 8421, a return portion 8422, and a communication portion 8423. The flow portion 8421 may communicate with the main passage 841, and condensate may flow from the main passage 841 into the flow portion 8421. The returning portion 8422 may communicate with the main passage 841 and the flowing portion 8421, and the returning portion 8422 and the flowing portion 8421 may be disposed in a straight line, and the flowing portion 8421 and the returning portion 8422 may be disposed in parallel. Of course, it is understood that the returning portion 8422 and the flow portion 8421 may not be limited to being arranged in a straight line, but may be arranged in a curved line in other embodiments. In other embodiments, the flow portion 8421 and the return portion 8422 may not be limited to being parallel, but may be distributed in a splayed shape. The communication portion 8423 may communicate the flow portion 8421 and the return portion 8422. The condensate can flow from the flowing portion 8421, pass through the communicating portion 8423, flow to the returning portion 8422, and return from the returning portion 8422 to the main passage 841.

Further, in the present embodiment, the first sealing element 80 may be provided with four through holes 85, and the through holes 85 may be distributed at four corners of the elastic body 81. The through hole 85 may be disposed through the elastic body 81 along a thickness direction of the elastic body 81, and may be used for a screw to pass through, so that the screw connects and fixes the first sealing element 80 and the bracket 20. In this embodiment, the via 85 may also be used for ventilation.

Further, in the present embodiment, the first sealing element 80 is provided with a pressure relief groove 86, and the pressure relief groove 86 can communicate with the fluid passage 84. In this embodiment, specifically, the pressure relief groove 86 may be disposed near the second opening 83, and one end thereof may be communicated with the fluid channel 84, and the other end thereof may be communicated with one of the through holes 85. The function of the pressure relief groove 86 is to stop the operation of the airflow sensing device 50 when the user does not suck, but the airflow hardly flows back to the airflow sensing device 50 because the flow resistance of the fluid channel 84 flowing from the first opening 82 to the second opening 83 is large, and at this time, the pressure relief groove 86 can supplement the air pressure to relieve the negative pressure state of the airflow sensing device 50 so as to ensure the normal operation of the airflow sensing device 50.

Further, in this embodiment, a positioning protrusion 87 may be disposed on the first sealing member 80, and the positioning protrusion 87 may be disposed on a side of the elastic body 81 opposite to the airflow sensing device 50 and may be configured to cooperate with the airflow sensing device 50 for positioning. In this embodiment, when the first sealing member 80 is pressed against the circuit board 40, the positioning protrusion 87 can be pressed against the airflow hole 401 of the circuit board 40. In this embodiment, the second opening 83 can be formed in the positioning protrusion 87. In this embodiment, a sealing rib 871 may be disposed on the protruding end surface of the positioning protrusion 87, and the sealing rib 871 may be disposed protruding toward the circuit board 40 and may be used to seal the gap between the second opening 83 and the circuit board 40.

Further, in the present embodiment, a sealing ring 88 cooperating with and sealing with a second sealing member 90 may be disposed on the first sealing member 80, and the sealing ring 88 may be disposed on the elastic body 81 and may be disposed along a circumferential direction of the elastic body 81.
