Specifically, as shown in fig. 5, 6, and 7, the circulating water tank device 1 includes an upper water tank body 206 and a lower water tank body 207, the upper water tank body 206 and the lower water tank body 207 are connected by sealing, a side surface of the lower water tank body 207 extending upward is an inclined surface, an inner concave clamping portion 201 convenient for installation and fixation is disposed at a top end of the inclined surface and an end portion of a side opposite to the water inlet and outlet mechanism 10, and an inner concave clamping groove 202 is disposed on the clamping portion. It is fixed during circulating water tank device 1, corresponding buckle on the cleaner can the lock be in the joint groove 202 of joint portion 201, need take out during circulating water tank device 1, loosen corresponding buckle and can take out circulating water tank device 1.

As a further improved embodiment, the tank upper body 206 and the tank lower body 207 are hermetically connected by an ultrasonic welding layer (not shown).

As a further improved embodiment, the tank upper body 206 and the tank lower body 207 are hermetically connected through a two-shot molding process.

As a further improved embodiment, the tank upper body 206 and the tank lower body 207 are hermetically connected through a direct bonding process.

Specifically, as shown in fig. 14, when the water inlet/outlet mechanism 10 of the circulating water tank device 1 is inclined downward, a part of the pressure relief mechanism 205 is located above the liquid level H on the side away from the water inlet/outlet mechanism 10, and the circulating water tank device 1 still has the capability of releasing pressure to the outside of the circulating water tank device and also has the capability of continuously outputting clean water to the outside regardless of whether the opening of the suction pipe 106 is always located below the liquid level H. When the water inlet of the suction pipe 106 is below the liquid level H, the natural suction pipe 106 can realize the effect of discharging water outwards. When the water inlet of the suction pipe 106 is above the liquid level H, the vent hole 1041 of the water inlet and outlet mechanism 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 through hole 1041 can realize the effect of "discharging water outwards" under the pressure of the liquid level H. Meanwhile, because the pressure difference exists between the inside and the outside of the circulating water tank device 1, the circulating water tank device of the cleaner used in the posture has the capacity of supplying water and releasing pressure to the outside at the same time.

Specifically, as shown in fig. 15, when the water inlet and outlet mechanism 10 of the circulating water tank device 1 is inclined upward, a part of the pressure relief mechanism 205 is located above the liquid level H at a side close to the water inlet and outlet mechanism 10, at this time, the opening of the suction pipe 106 is lower than the liquid level H, under the combined action of water pressure and air pressure, the pressure passes through the pressure relief mechanism 205 and acts directly on the air outlet nozzle 203 of the circulating water tank device 1 along a pressure relief pipeline, and the air outlet nozzle 203 may be specifically a one-way valve, and due to the one-way conduction action of the one-way valve, the one-way valve is compacted and closed under the combined action of water pressure and air pressure. The vent hole 1041 of the water inlet and outlet mechanism 10 is higher than the liquid level H and is only a tiny bypass branch of the water outlet channel 1024, the vent 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 vent hole 1041 is arranged in front of the vent hole 1041, and simply, the bypass branch of the vent 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 venthole 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. Of course, when the liquid level H is lower than the water inlet opening of the suction pipe 106, the circulating water tank device 1 cannot continuously output clean water to the outside, and the user is prompted to add clean water to the circulating water tank device 1 for further use.

As shown in FIG. 16, the present invention provides another embodiment of an electric scrubbing vehicle tool.

Different from the previous embodiment, the second pressure relief joint 2056 is changed into a three-way joint, so that the original three-way joint 2057 is omitted, the horizontal end interfaces of the first pressure relief joint 2055 and the second pressure relief joint 2056 are directly connected by the pressure relief hose 60, and the other vertical end interface of the second pressure relief joint 2056 is connected to the exhaust nozzle 203 by the pressure relief hose 60. The air outlet 203 is arranged near the tail of the circulating water tank device 1, so that the filter assembly 40 has more space to arrange a filter screen to increase the filtering effect on the basis of not increasing the diameter of the filter assembly, and meanwhile, the suction pipe 106 can be extended to be longer, so as to reduce the occurrence of the situation that the water inlet and outlet mechanism 10 is inclined upwards, and the water in and out of the circulating water tank device 1 is remained and cannot be used.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
