The utility model can realize the hot water supply on the front and rear sides of the main housing 100 by setting the first water outlet connector 410 and the second water outlet connector 420, meet the hot water supply needs inside and outside the vehicle, and is easy to use.

[0032] In actual application, the switch valve 430 can be a ball valve or a stop valve, and the pipeline system 400 and the heating system 300 can be set accordingly according to actual use needs. Since the structure of the heating system 300 of the embodiment of the utility model is known to ordinary technicians in this field, it will not be described in detail here.

[0033] In some embodiments, the piping system 400 includes a hot water pipe 440, a first three-way joint 450, a second three-way joint 460 and a safety valve 470. The heating system 300 is connected to the hot water pipe 440 and is capable of heating water in the hot water pipe 440. The end of the hot water pipe 440 is connected to one end of the first three-way joint 450, and the other two ends of the first three-way joint 450 are respectively connected to the second three-way joint 460 and the safety valve 470. One end of the second three-way joint 460 is connected to the first water outlet joint 410, and the other end is connected to the second water outlet joint 420 through the switch valve 430.

[0034] It is understandable that if Figure 2 and Figure 3 As shown, the hot water heated by the heating system 300 in the piping system 400 is transported through the hot water pipe 440, and the hot water pipe 440 is connected to the first three-way joint 450. The upper end of the first three-way joint 450 is connected to the safety valve 470. When the pressure in the hot water pipe 440 is high, the excess pressure can be released through the safety valve 470 to avoid accidents such as pipe burst caused by excessive pressure; the lower end of the first three-way joint 450 is connected to the second three-way joint 460, and the two can be connected through a pipe body. The rear end of the second three-way joint 460 is connected to the first water outlet joint 410 through the pipe body, and the front end thereof is connected to the switch valve 430 through the pipe body and connected to the second water outlet joint 420 through the switch valve 430, so as to realize the front and rear water outlet pipeline setting, which has a simple structure and is easy to use.

[0035] In some embodiments, the main shell 100 includes a first shell portion 110, a second shell portion 120 and a face frame 130. The first shell portion 110 and the second shell portion 120 are detachably connected to enclose an inner cavity 101. The face frame 130 is detachably connected to the front side of the first shell portion 110 and / or the second shell portion 120, and the opening of the inner cavity 101 is provided on the face frame 130.

[0036] It is understandable that if Figure 1 , Figure 2 and Figure 3As shown, the first housing part 110 has an "L"-shaped folded plate structure, and the second housing part 120 has a "冂"-shaped folded plate structure. The two are detachably connected through a threaded structure and / or a clamping structure to enclose an inner cavity 101. The face frame 130 is detachably connected to the front sides of the first housing part 110 and the second housing part 120 to form a hexahedron structure. The opening of the inner cavity 101 is provided on the face frame 130. Its structure is simple, which is convenient for the manufacture and installation of the main housing 100. In actual application, the main housing 100 can also be an integral structure or formed by combining multiple plate parts, which can be specifically set according to actual usage needs.

[0037] Further, the face frame 130 has a recessed part 102, and the opening of the inner cavity 101 is provided in the recessed part 102. The door body 200 is rotatably connected to the face frame 130 and can rotate into the recessed part 102. A first surrounding edge part 210 extending towards the recessed part 102 is provided at the edge of the door body 200, and a second surrounding edge part 131 extending towards the door body 200 is provided at the edge of the opening of the inner cavity 101.

[0038] It can be understood that as Figure 1 、 Figure 2 and Figure 3 shown, the face frame 130 has a recessed part 102 that recesses backward, and the opening of the inner cavity 101 is provided at the middle position of the recessed part 102. The door body 200 is rotatably connected to the face frame 130 and can rotate into the recessed part 102. A first surrounding edge part 210 extending backward is provided at the edge of the door body 200 to reduce the possibility of external rainwater entering the recessed part 102. A second surrounding edge part 131 extending forward is provided at the edge of the opening of the inner cavity 101 to reduce the possibility of rainwater entering the opening of the inner cavity 101, thereby reducing the possibility of rainwater entering the inner cavity 101 from the outer gap of the door body 200 and improving the waterproof performance. In actual application, the specific structures of the first surrounding edge part 210 and the second surrounding edge part 131 can be set accordingly according to actual usage needs.

[0039] In some embodiments, a baffle 132 is connected to the opening of the inner cavity 101. The second water outlet joint 420 penetrates through the baffle 132 and is exposed at the opening of the inner cavity 101. The baffle 132 can block the switch valve 430 in the front-rear direction.

[0040] It can be understood that as Figure 2 and Figure 3As shown, the baffle 132 is connected to the face frame 130, and a hole is provided on the baffle 132. The second water outlet connector 420 passes through the baffle 132 through the hole and is exposed to the opening of the inner cavity 101, so that the user can connect to the water outlet through the second water outlet connector 420. The switch valve 430 is located at the rear side of the baffle 132, so that the baffle 132 can cover the switch valve 430 in the front-to-back direction, which is helpful to prevent the second water outlet connector 420 from accidentally opening and discharging water due to accidental touch by a person. In actual application, the specific structure of the baffle 132 can be set accordingly according to actual use needs.

[0041] Furthermore, an air inlet hole 201 is provided on the door body 200, and the air inlet hole 201 is arranged corresponding to the baffle 132. The lower part of the baffle 132 is connected to the lower edge of the opening of the inner cavity 101, and the upper edge of the baffle 132 is not lower than the position of the air inlet hole 201 on the door body 200.

[0042] It is understandable that if Figure 1 , Figure 2 and Figure 3 As shown, the air inlet 201 is arranged on the lower side of the door body 200 and is provided with a plurality of them. The lower part of the baffle 132 is connected and fixed to the lower edge of the opening of the inner cavity 101, and its upper edge is higher than the position of the air inlet 201 on the door body 200, thereby effectively blocking the rainwater entering the air inlet 201 from entering the inner cavity 101 through the opening of the inner cavity 101, thereby improving the waterproof performance. In actual application, the upper edge of the baffle 132 can also be flush with the highest position of the air inlet 201 on the door body 200, which can be set accordingly according to actual use needs.

[0043] Furthermore, the baffle 132 is arranged to be tilted backward relative to the opening of the inner cavity 101. It is understandable that Figure 2 and Figure 3 As shown, there is a spacing distance between the lower side wall of the recessed portion 102 and the first surrounding edge portion 210 at the lower side of the door body 200 to form a drainage gap (not marked in the figure), and the baffle 132 is inclined relative to the face frame 130, so that the baffle 132 forms a downward inclined wall on the side facing the air inlet 201. When the rainwater entering the air inlet 201 is blocked by the baffle 132, the inclined wall can quickly guide the water on the baffle 132 to the lower side of the opening of the inner cavity 101 and flow out from the opening of the inner cavity 101, and then discharge it outward through the drainage gap below the door body 200, reducing the possibility of internal water accumulation; at the same time, such a design can make the water flow downward along the inclined wall of the baffle 132 when the second water outlet joint 420 leaks water at the connection with the external pipeline, or when the second water outlet joint 420 accidentally discharges water. Avoid water ingress into the inner cavity 101 and facilitate use. In actual application, the inclination angle of the baffle 132 can be set accordingly according to actual use needs.

[0044] In some embodiments, the switch valve 430 is a solenoid valve. A switch module is provided on the front side of the main housing 100 . The switch module is electrically connected to the switch valve 430 to control the opening and closing of the switch valve 430 .

[0045] It is understandable that by setting a switch module (not shown in the figure) on the front side of the main housing 100, the switch module may include an electrical switch button or an adjustment knob, etc., and the switch module is electrically connected to the switch valve 430. When in use, after opening the door body 200, the user can control the opening and closing of the switch valve 430 through the switch module, which is convenient for use. In actual application, the switch valve 430 can also be a combination of a ball valve and a driver, and the switch module controls the driver to act or stop, and the driver drives the ball valve to rotate to open or close, so as to realize electric control, which can be changed accordingly according to actual use needs.

[0046] In some embodiments, the second water outlet connector 420 is connected to a telescopic tube (not shown in the figure) that can be telescopically changed in length. It is understandable that by providing a telescopic tube, the telescopic tube is connected to the second water outlet connector 420. When hot water is needed outside the vehicle, the telescopic tube can be extended to the outside of the main housing 100, which is convenient for the user to use hot water through the telescopic tube; when there is no need to use hot water outside the vehicle, the telescopic tube can be shortened to be stored in the inner cavity 101, which is convenient for storage and use. In actual application, in addition to the above structure, the telescopic tube can also be provided between the switch valve 430 and the second water outlet connector 420. The specific setting can be made according to the actual use needs. Since the structure of the telescopic tube in the embodiment of the utility model is known to ordinary technicians in the field, it will not be described in detail here.

[0047] In some embodiments, the second water outlet connector 420 is detachably connected to a cover (not shown in the figure), and the cover can close the water outlet of the second water outlet connector 420. It is understandable that by detachably providing the cover on the second water outlet connector 420, when the second water outlet connector 420 is not needed, the water outlet of the second water outlet connector 420 can be closed by the cover to prevent foreign matter from entering or accidental water leakage; when the second water outlet connector 420 is needed, the cover can be detached from the second water outlet connector 420 to release the blockage of the water outlet of the second water outlet connector 420 for easy use. In actual application, the cover can be connected to the second water outlet connector 420 by a threaded structure or a screw-on structure, and its specific structure can be set accordingly according to actual use needs.

[0048] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
