The oxygen cell assembly 100 is mounted in the mounting groove 212 and is communicated with the air channel 210, so that the air flow in the air channel 210 flows through the oxygen cell assembly 100. Wherein, the ventilator body 21 is provided with two clamping grooves 214 in the mounting groove 212.

Referring to fig. 1 and 2, fig. 1 shows a schematic structural diagram of an oxygen battery assembly according to an embodiment of the application. Fig. 2 shows a schematic view of the internal structure of the oxygen cell assembly.

The oxygen cell assembly 100 includes a case 11, an oxygen cell main body 12 provided in the case 11, and a circuit board 13 electrically connected to the oxygen cell main body 12. Wherein, the oxygen cell assembly 100 is used for detecting the gas in the gas path 210

The housing 11 has a cylindrical shape as a whole. The housing 11 includes opposite front and rear ends 111, 115. The circuit board 13 is provided with a rear end 115. The front end 111 is remote from the circuit board 13. The housing 11 is provided with a housing cavity 113 and a side wall 112 surrounding the housing cavity 113. Specifically, the housing 11 includes a bottom portion 110, and a cylindrical side wall 112 extending around the bottom portion 110. The bottom 110 and the side walls 112 enclose a receiving cavity 113. That is, the end of the housing 11 remote from the base 110 is an opening 116. That is, the front end 111 forms an opening 116 through which the oxygen supply cell body 12 is inserted into the housing cavity 113, and the rear end 115 is one end of the bottom 110 of the housing 11.

The housing 11 is further provided with an engaging portion 114. The engaging portions 114 are symmetrically disposed outside the side wall 112. The engaging portion 114 includes a first connecting arm 1140 and a second connecting arm 1142. The first connecting arm 1140 extends outwardly from the side wall 112 in a direction perpendicular to the axis of the housing 11. The second connecting arm 1142 extends from the first connecting arm 1140 toward the rear end in a direction parallel to the axis of the housing 11.

The housing 11 is further provided with a first magnetic element 16 and a sealing element 17 at the front end 111. The first magnetic member 16 is embedded in the housing 11 and is flush with the end surface of the front end 111. In this embodiment, the first magnetic member 16 is two arc-shaped permanent magnets. The seal 17 is annular and is disposed on the side of the housing 11 that projects from the front end 111 away from the rear end 115.

Referring to fig. 3 in combination, fig. 3 shows a schematic diagram of a circuit board structure. The circuit board 13 is adjacent to the bottom 110. The circuit board 13 is provided with a connector 130, and the connector 130 is provided with a contact pin 131 and a second magnetic member 133. The connector 130 is attracted to the oxygen battery body 12 through the second magnetic member 133, so that the contact pins 131 are electrically connected to the oxygen battery body 12 to drive the oxygen battery assembly 100 to operate. The number of the second magnetic elements 133 is two, and the contact pins 131 are plural and are arranged in a straight line. Specifically, the contact pins 131 are positive, negative, and signal pins. The second magnetic pieces 133 are disposed on two sides of the contact pins 131, and the magnetism of the two second magnetic pieces 133 is opposite. Wherein the first magnetic member 16 and the second magnetic member 133 are permanent magnets.

When the oxygen battery assembly 100 is assembled, a circuit board 13 and a first magnetic piece 16 are arranged in a shell 11, then an oxygen battery main body 12 is inserted into a containing cavity 113 of the shell 11 through an opening 116, so that the oxygen battery main body 12 is connected with the circuit board 13, and then electric connection is established, a gas passage hole 117 is formed between the front end 111 and the oxygen battery main body, and the gas passage hole 117 is communicated with a gas passage 210; finally, a seal 17 is mounted to the front end 111 of the housing 11.

The first magnetic member 16 is fixed to the ventilator body 21. Since the sealing ring 17 protrudes from the front end 111, when the oxygen battery assembly 100 and the ventilator body 21 are fixed together, the sealing ring 17 will be pressed by the oxygen battery assembly 100 and the ventilator body 21, so that the oxygen battery assembly 100 has better tightness, and the probability of internal gas leakage and external gas introduction is reduced.

When the oxygen cell module 100 is detached from the ventilator 200, the oxygen cell module 100 can be detached from the ventilator 200 by simply rotating the detached oxygen cell module 100 to separate the engaging portion 114 from the engaging groove 214.

When the oxygen cell body 12 needs to be removed from the oxygen cell assembly 100, the oxygen cell body 12 can be taken out of the housing 11 by applying a sufficient external force against the suction force between the oxygen cell body 12 and the circuit board 13.
