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

Further, in the present embodiment, the first sealing member 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 sealing member 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 may be located on the elastic body 81 and disposed near the second end wall 24 and is in communication with the air inlet 241 of the second end wall 24, and the first opening 82 may allow air to flow out and into the air inlet 241 of the second end wall 24, and if condensate is present, it may allow condensate to flow in. The second opening 83 may be disposed on the elastic body 81 and disposed near the blocking wall 25. The second opening 83 can be in communication with the airflow hole 401 on the circuit board 40, and further in communication 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 misplaced. Specifically, the second opening 83 and the airflow hole 401 of the circuit 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 circuit board 40. The fluid passage 84 may communicate the first opening 82 and the second opening 83. When the user sucks, air can pass through the air flow sensing device 50 and 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 may be output from the intake aperture 241 into the first opening 82 and into the fluid passage 84, and may be stored in the fluid passage 84. In this embodiment, the flow path of the condensate flowing from the first opening 82 into the second opening 83 through the flow path 84 may be designed to be longer than the flow path of the condensate flowing from the second opening 83 into the first opening 82 through the flow path 84, i.e., the flow path has different flow resistances for different flow directions, so that the condensate can normally flow to the first opening 82 to achieve the normal operation of the airflow sensing device 50, while the condensate can hardly flow to the second opening 83, thereby avoiding the condensate from corroding the airflow sensing device 50 and the circuit board 40.

Further, in the present embodiment, the fluid channel 84 includes a main channel 841 and at least one return channel 842. The main channel 841 may be centrally disposed and may 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 will be appreciated that in other embodiments, the primary channel 841 is not limited to being centrally located, nor to being in a straight line distribution. The number of return channels 842 may be plural, and the plurality of return channels 842 may be provided side by side on opposite sides of the main channel 841. Of course, it will be appreciated that in other embodiments, there may be only one of the return channels 842. The return path 842 may be in communication with the main path 841, which may increase the fluid path, thereby reducing the return of condensate to the circuit board 40, and avoiding condensate from contaminating the circuit board 40 and the air flow sensing device 50. In this embodiment, the return channel 842 may be inclined toward the second opening 83 and may form a set angle with the main channel 841, in this embodiment, the set angle may be an acute angle, specifically, the set angle may be 30-60 degrees, preferably 45 degrees, and by inclining the return channel 842 at an acute angle with respect to the longitudinal axis of the main channel 841, the structural space may be optimized.

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 return portion 8422 may communicate with the main passage 841 and the flow portion 8421, and the return portion 8422 and the flow portion 8421 may be disposed in a straight line, and the flow portion 8421 and the return portion 8422 may be disposed in parallel. Of course, it is understood that in other embodiments, the return portion 8422 and the flow portion 8421 may not be limited to a straight arrangement, but may be curved. In other embodiments, the flow portion 8421 and the return portion 8422 may not be limited to being disposed in parallel, but may be distributed in a splayed configuration. The communication portion 8423 can be used to communicate the flow portion 8421 and the return portion 8422. Condensate can flow from the flow portion 8421, through the communication portion 8423, to the return portion 8422, and from the return portion 8422 back to the main passage 841.

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

Further, in the present 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 positioned in cooperation with the airflow sensing device 50. In this embodiment, the positioning protrusion 87 can be pressed onto the airflow hole 401 on the circuit board 40 when the first sealing member 80 is pressed onto the circuit board 40. In the present embodiment, the second opening 83 may 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.
