As a further improved embodiment, a vent duckbill valve 34 may be further provided at the vent valve mounting step 3171, and reverse filling into the relief groove through the relief rear-stage passage 317 by the external pressure of the tank can be effectively prevented by utilizing the one-way conduction characteristic of the vent duckbill valve 34.

Specifically, as shown in fig. 5, 6 and 7, when in use, the water tank is in a moving state and is not in a horizontal state basically for a long time, and when two pressure release control switches are not in the same horizontal line, one of the pressure release control switches is in a closed state, so that one pre-pressure release port 316 is necessarily communicated with the cavity of the water tank, and the pressure in the cavity can be released, so that the pressure inside and outside the water tank is balanced, and negative effects caused by unbalanced pressure in the water tank are effectively reduced; even when the circulation cleaning container is in a horizontal state, the two pressure release control switches are in the same horizontal line, one pressure release control switch can be flushed by liquid in the containing cavity under the inertia effect, so that the pressure in the containing cavity can be released by the way that the pre-pressure release opening 316 is communicated with the containing cavity, the internal pressure and the external pressure of the circulation cleaning container are balanced, and negative effects caused by unbalanced pressure in the circulation cleaning container are effectively reduced. The pressure release control switch comprises a gravity ball 33, an elastic sleeve 32 capable of limiting the movement of the gravity ball 33, a pre-pressure release through hole arranged in the elastic sleeve 32 and a limiting part 315 for limiting the movement position of the gravity ball 33.

When the cleaning roller is used for continuous cleaning, part of air contained in the gap of the cleaning roller scrubbing sponge layer generated during the extrusion of the cleaning roller enters the cleaning liquid loop along with the extruded water in the automatic cleaning process of the cleaning roller, so that the loop pressure is increased, the loop liquid conveying efficiency is low, and the accumulated pressure in the cleaning liquid loop can "wash away" the sealing structures of joints, joints and other parts in the conveying pipeline in severe cases, so that the performance of the vehicle cleaning device is seriously affected.

Specifically, as shown in fig. 5, 6 and 7, since the gravity ball 33 is freely movable in the pressure release groove, the two pressure release control switches are disposed on the same horizontal line, and when the two pressure release control switches are parallel to the horizontal plane, it is theoretically possible that the two pressure release control switches are both in an off state, an on state or one off-on state. Because the water tank can possibly generate pressure increase when in use, and the water tank is in a motion state when in use, the two pressure release control switches can not be in a horizontal state for a long time at the same time, and thus, only one of the two pressure release control switches is in an on state and the other pressure release control switch is in an off state. Thereby ensuring that at least one pre-pressure relief port 316 is communicated with the outside of the water tank through a pressure relief rear section channel 317 and an exhaust channel 213 in the use process, and realizing that the inside and the outside of the water tank are in a pressure balance state.

As a further improved embodiment, in order to better ensure that the pressure balance can be achieved when the two pressure release control switches are on the same horizontal plane, the bottom of the pressure release groove is provided with an inclined plane (not shown in the figure) for enabling the gravity ball 33 to move towards the direction of the pressure release opening 316 and a straight horizontal plane (not shown in the figure) for connecting the bottom of the inclined plane with the pressure release opening 316, when the two pressure release control switches are on the same horizontal plane, even if the gravity ball 33 makes the pressure release opening 316 non-conductive, the gravity ball 33 of one pressure release control switch can be flushed away by the liquid in the water tank under the action of inertia, and the gravity ball 33 is easier to separate from the closing position of the pressure release opening 316, so that the pressure release opening 316 is inevitably communicated with the water tank through the pressure release rear-section channel 317, so that the pressure in the water tank can be released, and the internal pressure and the external pressure of the water tank are balanced.

According to the need, as shown in fig. 5, 6 and 7, the elastic sleeve 32 can effectively reduce the noise generated by the impact of the gravity ball during the movement, and the elastic sleeve 32 is made of elastic materials such as silica gel. The elastic sleeve 32 adopts a horn-shaped structure (not shown in the figure), so that a better switching effect can be achieved.

When the water tank needs to be changed or the pressure relief and filtration integrated device 3 in the water tank needs to be deeply cleaned, the water tank is separated from the body of the vehicle cleaner by external force, and then the liquid in the water tank is poured and the new liquid is refilled; or, further pull out whole tank lid subassembly 4, further slide outwards take out pressure release filtration integrative device 3 through the handle on the pressure release filtration integrative device 3 and carry out the deep cleaning back installation again, thereby this is again with the external force with tank lid subassembly 4 lid water tank body subassembly 2 to accomplish this time change cleaning solution or to the deep cleaning action of pressure release filtration subassembly 3.
