As shown in fig. 7 and 8, the pressure to be released in the water tank firstly enters the pressure releasing filter assembly 3 through the filter screens 304 arranged on the two sides and the bottom surface of the framework of the filter assembly 30, and then continuously enters the pressure releasing groove through the pressure releasing notches 318 at four positions, one of the two gravity balls 33 blocks the pre-pressure releasing through hole in the corresponding elastic sleeve 32, and the other gravity ball 33 opens the pre-pressure releasing through hole in the corresponding elastic sleeve 32, and after the pressure to be released crosses the limiting portion 315 corresponding to the gravity ball 33 which opens the pre-pressure releasing through hole, the pressure to be released continuously enters the pressure releasing channel inlet 3172 along the notch on the side wall of the pressure releasing groove, and then flows along the pressure releasing channel 317 to the exhaust port 302, and is released out of the water tank through the exhaust port 103 of the water tank bayonet assembly 1. The pressure relief notch 318, the pressure relief groove and the pressure relief rear-section channel form a complete pressure relief channel together.

As shown in fig. 8, as a further improved embodiment, an exhaust duckbill valve 34 may be further disposed at the exhaust valve mounting step 3171, and reverse filling of the external pressure of the water tank into the pressure relief groove through the pressure relief back-end passage 317 may be effectively prevented by using the one-way conduction characteristic of the exhaust duckbill valve 34.

Specifically, as shown in fig. 6, 7 and 8, when the pressure-relief control switch is used, the water tank is in a motion state, and basically cannot be in a horizontal state for a long time, when two pressure-relief control switches are not in the same horizontal line, one of the pressure-relief control switches is in a closed state, so that one pre-pressure-relief port 316 is inevitably communicated with the cavity of the water tank, and thus, the pressure in the cavity can be released, the internal and external pressures of the water tank are balanced, and negative effects caused by imbalance of the pressures in the water tank are effectively reduced; when the circular cleaning container is in a horizontal state, at the moment, the two pressure relief control switches are in the same horizontal line, one pressure relief control switch can be flushed away by liquid in the cavity under the action of inertia, so that a pre-pressure relief port 316 is communicated with the cavity, the pressure in the cavity can be released, the internal pressure and the external pressure of the circular cleaning container are balanced, and negative influences caused by pressure imbalance in the circular cleaning container are effectively reduced. The pressure relief control switch comprises a gravity ball 33, an elastic sleeve 32 capable of limiting the motion of the gravity ball 33, a pre-pressure relief through hole arranged in the elastic sleeve 32 and a limiting part 315 for limiting the moving position of the gravity ball 33.

When the cleaner continuously cleans by adopting the cleaning roller, in the automatic cleaning process of the cleaning roller, part of air generated when the cleaning roller is extruded enters the cleaning liquid loop along with extruded water, so that the loop pressure is increased, the loop liquid conveying efficiency is low, and in severe cases, the pressure accumulated in the cleaning liquid loop can flush away the sealing structures at the joints, the joints and the like in the conveying pipeline, so that the cleaning liquid loop leaks, and the performance of the cleaner is seriously influenced.

Specifically, as shown in fig. 6, 7, and 8, since the gravity ball 33 can freely move in the pressure relief groove, and the two pressure relief control switches are disposed on the same horizontal line, when the two pressure relief control switches are parallel to the horizontal plane, theoretically, both of the two pressure relief control switches may be in an off state, an on state, or one of the two on states. The pressure increase condition can be generated when the water tank is used, and the water tank is in a motion state when the water tank is used, so that the two pressure relief control switches cannot be in a horizontal state for a long time at the same time, and only one of the two pressure relief control switches is in an on state and the other one is in an off state. Therefore, at least one pre-decompression opening 316 is communicated with the outside of the water tank through the decompression rear-section channel 317 and the exhaust opening 103 in the using process, and the inside and the outside of the water tank are in a pressure balance state.

As shown in fig. 6, 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) which enables the gravity ball 33 to move towards the pre-pressure release opening 316 and a straight horizontal plane (not shown) which connects the bottom of the inclined plane and the pre-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 pre-pressure release opening 316 non-conductive, the gravity ball 33 of one of the pressure release control switches can be flushed away by the liquid in the water tank under the inertia effect, and the gravity ball 33 is inevitably easier to leave the closed position of the pre-pressure release opening 316, so that one pre-pressure release opening 316 is inevitably communicated with the water tank through the pressure release rear-stage channel 317, so that the pressure in the water tank can be released, thereby balancing the pressure inside and outside the water tank.

As shown in fig. 1 and 2, the integrated water tank for the vehicle cleaner further includes a water tank cover assembly 4 covering the open end of the water tank body assembly 2, and the water tank cover assembly 4 includes a water tank cover body (not shown), a water tank cover outer body (not shown) sleeved outside the water tank cover body, and a water filling flip cover (not shown) installed on the water tank cover body.

When the water tank needs to change water or the pressure relief filter assembly 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 new liquid is injected again; or, further pull down whole tank lid subassembly 4, further slide through the handle on stating pressure release filtering component 3 and outwards take out pressure release filtering component 3 and carry out the deep cleaning after again install back, thereby this again with external force with water tank lid subassembly 4 lid close water tank body subassembly 2 and accomplish this change cleaning solution or to the deep cleaning action of pressure release filtering component 3.
