[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] See Figure 1 、 Figure 2 The hood 12 is provided with a check valve 5, which can prevent exhaust gas from entering the vehicle through the exhaust port.

[0025] It should be noted that the top cap 11 , the brim 12 , and the cap body 13 may also be an integrally formed structure.

[0026] See Figure 2 、 Figure 3 The exhaust pipeline includes a one-way valve 5, an air pipe 7, a pipe joint 6, and a through-cabin ventilation joint 2 which are connected in sequence along the exhaust direction. The one-way valve 5 is fixedly connected to one end of the air pipe 7, and the other end of the air pipe 7 is threadedly connected to one end of the pipe joint 6. The other end of the pipe joint 6 is threadedly connected to one end of the through-cabin ventilation joint 2, and the other end of the through-cabin ventilation joint 2 is threadedly fixed to the rain cap 1. The threaded connection makes the entire rainproof exhaust device detachable, which is convenient for installation and maintenance; at the same time, the one-way valve 5, air pipe 7, pipe joint 6, and through-cabin ventilation joint 2 are small in size and simple to install. No pre-installation is required, and they are convenient for later installation on both sides of the vehicle body or on the roof.

[0027] See Figure 2 、 Figure 3 The through-cabin ventilation joint 2 is fixedly connected to the vehicle wall 10 in the circumferential direction, with part of it located outside the vehicle wall 10 and part of it located inside the vehicle wall 10. The circumferential outer wall of the through-cabin ventilation joint 2 located outside the vehicle wall 10 abuts against the outer side of the vehicle wall 10 through the sealing gasket 3, and the circumferential outer wall of the through-cabin ventilation joint 2 located inside the vehicle wall 10 is fastened to the vehicle wall 10 through the mounting nut 4. The through-cabin ventilation joint 2 is threadedly connected to the mounting nut 4. A flat washer 8 and a spring washer 9 are also sleeved on the through-cabin ventilation joint 2. The mounting nut 4 abuts against the flat washer 8 through the spring washer 9, and the flat washer 8 abuts against the vehicle wall 10.

[0028] The mounting nut 4, the one-way valve 5, the pipe joint 6 and the air pipe 7 are all located on the inner side of the vehicle wall 10. The through-cabin ventilation joint 2 is provided with a central channel, an air inlet 201 and an air outlet 202. The air inlet 201 is connected with the air outlet 202 through the central channel, wherein the air inlet 201 is provided at the bottom of the through-cabin ventilation joint 2 and is connected with the pipe joint 6, the air pipe 7 and the one-way valve 5. The inlet of the one-way valve 5 forms the air inlet of the exhaust pipe, and the air outlet 202 forms the exhaust port. The air outlet 202 is evenly arranged along the radial direction of the through-cabin ventilation joint 2. In this embodiment, there are six of them. Of course, there can also be two, three, four, etc., but it is not limited to this.

[0029] How it works: See Figure 2 、 Figure 4 The exhaust gas generated by the equipment in the vehicle enters the air pipe 7 through the one-way valve 5 connected in series with the air pipe 7, passes through the pipe joint 6 and enters the air inlet 201 of the through-cabin ventilation joint 2, passes through the air path to the central channel of the through-cabin ventilation joint 2 and the air outlet 202 and is discharged outside the vehicle.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
