Once filter assembly 40 is disconnected from waterway connector 10, which may result in the flow of wastewater bypassing the filter assembly and re-entering outlet channel 1024, the risk of the flow line becoming clogged increases as the length of use increases.

Specifically, as shown in fig. 1 and 3, the pressure relief assembly 30 includes a pressure relief pipe 302 located in the water tank and a mounting member 301 connected to the pressure relief pipe, the mounting member being fixed to a connection seat 204 on the water tank, and the water tank is provided with a one-way pressure relief opening 203 in an area defined by the connection seat 204, and the one-way pressure relief opening is communicated with the water tank through the pressure relief pipe. As shown in FIG. 3, the pressure relief pipe is a hard pressure relief pipe, and a pressure relief air hole 3021 communicated with the water tank is arranged at the free end of the hard pressure relief pipe. The pressure relief vent 302 is close to the side wall of the water tank at the opposite side of the connecting seat. At least, be equipped with the filter screen (the attached drawing does not mark) around the pressure release gas pocket, can utilize the less pore of filter screen and the surface tension of water through proper setting, can form the water film on the filter screen surface, effectively prevent liquid to get into, simultaneously because when having pressure, the upper surface of filter screen forms the water film and can not withstand voltage, and pressure is discharged through the water film by the pressure release very easily. The pressure relief air hole is close to the upper wall of the water tank when the vehicle cleaning tool is used conventionally, so that the pressure relief air hole can exceed the liquid level of the cleaning solution in the water tank under the condition that the vehicle cleaning tool is not shaken vigorously or pushed and pulled forward and backward at a high speed, and the effect of regulating the air pressure in the water tank can be ensured to be exerted under the pressure relief assembly in the current state.

Specifically, as shown in fig. 2 and fig. 3, the bottom of the water tank is an inclined plane, a concave clamping portion 201 convenient for installation and fixation is arranged at the top end of the inclined plane at the bottom of the water tank and at a side end portion opposite to the waterway connector 10, and the clamping portion is further provided with a clamping groove 202 continuing to be concave.

Specifically, as shown in fig. 5, 7 and 8, a port (not shown in the drawings) connected to the suction pipe 106 is disposed at an end of the waterway connector 10 near the reservoir cavity, the suction pipe 106 extends to the bottom of the filter assembly 40, the sewage flowing back to the cavity of the reservoir 20 is filtered by the filter assembly 40 to become relatively clean water, and the clean water is sucked into the waterway connector 10 through the suction pipe 106 and then is transported to the surface of the cleaning roller scrubbing sponge layer (not shown in the drawings) through a pipeline. The length of the barrel 106 should not be too short, which would cause the barrel 106 to not suck clean water when the water supply is tilted upward (as shown in fig. 8) and the liquid level H is too low. The length of the water suction pipe 106 is slightly shorter than the length of the filter assembly 40, so that the water suction of the water inlet pipe can be smoothly ensured when the water supply device inclines upwards and the liquid level is too low, the water inlet (not shown in the drawing) of the water suction pipe 106 is arranged at the tail end of the water inlet pipe, further, a plurality of water inlet holes (not shown in the drawing) are formed in the side wall of the water inlet pipe, the plurality of water inlet holes are distributed in the length direction and the circumferential direction of the whole water inlet pipe, a certain gap is reserved between the bottom wall and the side wall of the water inlet holes and the filter assembly 40, so that the filter assembly 40 is ensured to have a certain space besides the filtering effect of the filter screen, the filtered clean water has a certain flow rate gradual change space in space, and impurities are prevented from being accumulated around the water inlet holes. The advantages that a plurality of water inlet holes are distributed in the length direction and the circumferential direction of the whole water inlet pipe are that: regardless of whether the water supply device is tilted upward (as shown in fig. 8) or tilted downward (as shown in fig. 7), the water inlet and/or the water inlet hole can suck enough fresh water to allow the vehicle washing apparatus equipped with the water supply device to work normally.

Specifically, as shown in fig. 7, when the clean water output assembly of the water supply device is inclined downward, the connecting base 204 is arranged on one side of the water tank far away from the clean water output assembly 102, the mounting piece 301 connected with the pressure relief pipe 302 is mounted on the connecting base 204 on the water tank, the area limited by the connecting base 204 is provided with the one-way pressure relief opening 203 of the water tank, the one-way pressure relief opening is communicated with the water tank through the pressure relief pipe, and the pressure relief pipe is made of hard material. Because the connecting seat 204 is arranged on one side of the water tank far away from the clear water output assembly, the pressure relief air hole 3021 at the free end of the hard pressure relief pipe, which is communicated with the water tank, naturally approaches the side wall of the water tank (the upper wall of the water tank when the vehicle cleaning tool is used conventionally) on the opposite side of the connecting seat, at this moment, the pressure relief air hole 3021 exceeds the liquid level H, and when the water suction pipe 106 is always positioned below the liquid level H, the water supply device naturally has the capability of relieving pressure outside the water supply device and also has the capability of continuously outputting clear water outwards. When the water inlet of the suction pipe 106 is above the liquid level H, the water outlet hole 1041 of the water channel interface 10 is lower than the liquid level H and is only a tiny bypass branch of the water outlet channel 1024, and the bypass branch of the water outlet hole 1041 can realize the effect of "discharging water outwards" under the pressure of the liquid level H. At this time, the relief passage of the relief vent 3021 communicating with the outside atmosphere has a capability of releasing the pressure to the outside of the water supply apparatus. Meanwhile, since there is a pressure difference between the inside and the outside of the water supply device, the water supply device of the car washing device used in such a posture has a capability of releasing pressure to the outside of the water supply device.

Specifically, as shown in fig. 8, when the clean water output assembly of the water supply device is inclined upwards, the connecting seat 204 is arranged on one side of the water tank far away from the clean water output assembly 102, the mounting part 301 connected with the pressure relief pipe 302 is mounted on the connecting seat 204 on the water tank, the area limited by the connecting seat 204 is provided with the one-way pressure relief port 203 of the water tank, the one-way pressure relief port is communicated with the water tank through the pressure relief pipe, and the pressure relief pipe is made of a hard material. Because the connecting seat 204 sets up the one side of keeping away from clear water output assembly on the water tank, the pressure release gas pocket 3021 with the water tank intercommunication at the stereoplasm pressure release pipe free end is just natural approaching the water tank lateral wall (the water tank upper wall when vehicle burnisher used conventionally) of connecting seat offside, at this moment, pressure release gas pocket 3021 is less than liquid level H, under the common effect of water pressure and atmospheric pressure, pressure passes through pressure release gas pocket 3021 and directly acts on the one-way pressure release mouth 203 of water tank along pressure release pipe 302, one-way pressure release mouth 203 can specifically be the check valve, because the check valve one-way conduction effect, the check valve is closed by the compaction under the common effect of water pressure and atmospheric pressure. The water outlet hole 1041 of the water channel interface 10 is higher than the liquid level H and is only a tiny bypass branch of the water outlet channel 1024, the water outlet hole 1041 is communicated with the outside atmosphere, a bypass structure (not shown in the drawing) for blocking the water flow from the bypass branch of the water outlet hole 1041 is arranged in front of the water outlet hole 1041, and simply, the bypass branch of the water outlet hole 1041 communicated with the outside atmosphere can achieve the effects of air permeability and water impermeability. At this time, the bypass branch of the water hole 1041 communicating with the outside atmosphere has a capability of releasing the pressure to the outside of the water supply apparatus. Meanwhile, because pressure difference exists between the inside and the outside of the water supply device, and the water inlet and/or the water suction hole which is positioned below the liquid level H are always arranged on the water suction pipe 106, the clean water output assembly can continuously output clean water outwards. The water supply device of the car washing device used in the posture has the capability of releasing pressure outside the water supply device and the capability of continuously outputting clean water outwards.

Because the water tank is provided with the filtering component, the recovered sewage can be reused after being filtered, the utilization efficiency of the water in the water tank can be improved, and the cleaning time is prolonged. Meanwhile, the pressure relief assembly is arranged, so that the pressure of the water tank can be increased and released in the sewage utilization process. In addition, the water tank is only provided with a backwater inlet and a clear water outlet, so that the difficulty of setting the water tank is reduced, and the manufacturing difficulty is reduced.

According to the requirement, the water outlet interface end connector and the backwater interface end connector are of an integrated structure, and the backwater cavity and the water outlet cavity are mutually independent. In order to better realize the fixation of the sealing ring, the backwater thimble and the water outlet thimble are respectively provided with a fixing groove for fixing the backwater sealing ring and the water outlet sealing ring.
