[0027] like Figures 1 to 7 As shown, a quick-connect shell for a ventilation device includes a shell body 10, and the shell body 10 is provided with a buckling part that cooperates with an external ventilation fan, and the buckling part is provided with a buckling hole 11. The buckling hole 11 and the snap-in block reserved at the external ventilation fan are matched and buckled with each other, and an unfastening slider 20 is provided above the buckling hole 11. The unfastening slider 20 is slid to realize the ejection of the snap-in block located in the buckling hole 11 and thus realize the unfastening of the shell body 10. When installing the ventilation device, the snap-in hole 11 is snapped with the snap-in block reserved for the external ventilation fan to realize the connection between the outer shell body 10 and the ventilation fan, so as to facilitate the fixation of the filter assembly. In this embodiment, filter cotton is mostly used as the filter assembly. The filter cotton is used to filter the air entering the electrical cabinet to prevent dust or other debris from entering the electrical cabinet and affecting the electrical components in the electrical cabinet, so as to improve the stability and safety of the electrical cabinet. When the filter cotton needs to be replaced, the unlocking slider 20 is pushed. As the unlocking slider 20 is pushed, the snap-in block located in the snap-in hole 11 is pushed out of the snap-in hole 11, so as to realize the rapid separation of the outer shell body 10 and the ventilation fan, so as to facilitate the rapid replacement of the filter cotton, thereby improving the disassembly and assembly efficiency between the outer shell body 10 and the ventilation fan.

[0028] A plurality of connection baffles 12 are provided at the upper end of the buckle part, and each connection baffle 12 is relatively arranged at two sides of the buckle hole 11. A first connection clamping platform 13 protruding outward is provided on the side of the connection baffle 12 away from the buckle hole 11. A connection groove 21 is provided in the middle of the release slider 20, and a second connection clamping platform 22 corresponding to the first connection clamping platform 13 is provided on the inner wall of the connection groove 21. The release slider 20 is relatively slidably connected with the buckle part through the cooperation of the first connection clamping platform 13 and the second connection clamping platform 22. In this embodiment, the connection baffle 12 is provided on the buckle part, and the outer side of the connection baffle 12 is protruded outward to form the first connection clamping platform 13, and the second connection clamping platform 22 corresponding to the first connection clamping platform 13 is formed inside the connection groove 21 of the release slider 20. The first connection clamping platform 13 and the second connection clamping platform 22 cooperate to realize the movable connection between the release slider 20 and the shell body 10.

[0029] A reset elastic plate 14 is provided at the upper end of the buckle part. The reset elastic plate 14 is located at the front side of the buckle hole 11. The reset elastic plate 14 is located in the connection groove 21 and abuts against the release slider 20. The reset elastic plate 14 is used to push the release slider 20 forward and reset it. In this embodiment, a reset elastic plate 14 is provided on the buckle part. The reset elastic plate 14 is used to replace the spring in the prior art. In the prior art, the release slider 20 is usually reset by a spring. However, since the spring has a certain fatigue type, maintaining a certain tension for a long time can easily cause the spring to be too fatigued and lose tension, thereby reducing or eliminating the reset effect. Therefore, in this embodiment, the release slider 20 is reset by using the reset elastic plate 14 to improve the reset efficiency of the release slider 20.

[0030] A plurality of reset reinforcement blocks 15 are provided at the lower end of the reset elastic plate 14.

In this embodiment, a plurality of reset reinforcement blocks 15 are provided at the lower end of the reset elastic plate 14, so that the strength of the reset elastic plate 14 is improved through the reset reinforcement blocks 15, thereby improving the service life of the reset elastic plate 14.

[0031] The thickness of the reset reinforcement block 15 located at the front side of the reset elastic plate 14 is greater than the thickness of the reset reinforcement block 15 located at the rear side of the reset elastic plate 14. In this embodiment, two reset reinforcement blocks 15 are arranged at the front end of the reset elastic plate 14, and one reset reinforcement block 15 is arranged at the rear side of the reset elastic plate 14, and the thickness of the reset reinforcement block 15 located at the front side of the reset elastic plate 14 is greater than the thickness of the reset reinforcement block 15 located at the rear side of the reset elastic plate 14, so as to strengthen the front and rear sides of the reset elastic plate 14, and at the same time, the front side strength of the reset elastic plate 14 is greater than the rear side strength, so as to facilitate the reset adjustment of the tripping slider 20.

[0032] An auxiliary reset block 23 is provided on one side of the connection groove 21 close to the reset elastic plate 14. The auxiliary reset block 23 is provided with an inclined reset surface, and the auxiliary reset block 23 abuts against the reset elastic plate 14 through the reset surface. In this embodiment, the auxiliary reset block 23 is provided in the connection groove 21, and the reset surface of the auxiliary reset block 23 abuts against the upper end of the reset elastic plate 14, thereby facilitating the reset guidance of the reset elastic plate 14, so as to improve the reset efficiency of the tripping slider 20.

[0033] The release slider 20 is provided with a release push hole 24, through which a thrust can be applied to the release slider 20. In this embodiment, the user can apply a certain thrust to the release slider 20 through the release push hole 24, so that the release slider 20 slides to achieve release. In addition, the release push hole 24 can also become the auxiliary ventilation hole 18 of the shell body 10 when not in use, so as to improve the ventilation efficiency of the shell body 10 through the release push hole 24.

[0034] The buckle portion is provided with a connecting guide plate 16, which is provided at the front side of the buckle hole 11 and at the rear side of the resetting elastic plate 14. The connecting guide plate 16 is provided with a connecting guide groove on the side facing the buckle hole 11, and the connecting guide groove is inclined from bottom to top. In this embodiment, the connecting guide plate 16 is provided at the buckle hole 11 to guide the clamping block on the ventilating fan so that the clamping block enters the buckle hole 11 through the connecting guide plate 16 for buckling.

[0035] A plurality of ventilation baffles 17 spaced apart from each other are provided on one side of the housing body, and ventilation holes 18 are formed between two adjacent ventilation baffles 17. In this embodiment, there are a plurality of ventilation baffles 17 on the surgical body, and ventilation holes 18 are formed between the ventilation baffles 17 to facilitate air flow on the ventilation device.

[0036] The buckle portion is provided with an anti-tripping plug 30, which is inserted on the side of the tripping slider 20 for sliding and unlocking. In this embodiment, the anti-tripping plug 30 is provided to facilitate the tripping slider 20 to be abutted, thereby preventing the tripping slider 20 from automatically sliding and unlocking in an unmanned environment, thereby improving the connection stability of the housing body 10.

[0037] In addition, the release slider 20 used in this embodiment is relatively small in size, which can maximize the ventilation efficiency of the housing body 10 .
