The housing 30 is open at one end and sealed to the entire circulation cleaning vessel by a gasket (not shown) that snaps onto the interface mechanism 32. The housing 30 includes a lower housing 301 having an inclined surface, so that the assisting guidance of the inclined surface can be more conveniently utilized, the end of the interface mechanism 32 is first clamped to the car washer body (not shown), then the entire circulating cleaning container is pressed down, and finally the clamping port 3021 at the top end of the inclined surface of the lower housing is clamped and fixed to the car washer body, thereby completing the fixation of the entire circulating cleaning container on the car washer body. The inclined plane of lower casing is convenient for observe the whole in-process that circulates the cleaning container of installation whether have other debris to interfere, and the in-process of taking out also does not regard for whole circulation cleaning container degree of depth too deeply and cause and the joint tongue (not marked in the figure) that corresponds to interfere, and the inclined plane also helps the clearance between buckle inclined plane and the car washer fuselage more convenient after the joint tongue shrink to it is more convenient to take out whole circulation cleaning container.

Specifically, as shown in fig. 3, the pressure balance mechanism 31 may be inseparably or detachably connected to the upper housing 301 by various means such as bonding, welding, fastening, and the like. Considering that the pressure balance mechanism 31 of the circulation cleaning container with the pressure balance function needs to be disassembled, maintained and replaced in the actual practical process, the pressure balance mechanism 31 can be inseparably connected or detachably connected with the upper shell 301 in advance, and then the upper shell 301 and the lower shell 302 provided with the pressure balance mechanism 31 are hermetically connected through the ultrasonic welding layer 303 in the actual production and manufacturing process of the circulation cleaning container according to the requirement, so that the production and manufacturing of the shell 30 are completed.

Of course, the housing 30 can also be manufactured by other integrated molding methods, in which case, the upper housing 301 is the upper half of the housing 30 and the housing 302 is the lower half of the housing 30. The pressure balance mechanism 31 can be connected to the upper half of the housing 30 in a non-separable or separable manner by various means such as bonding, welding, fastening, etc., and the detailed operation process will not be described herein.

Specifically, as shown in fig. 3, the pre-pressure-relief opening control assembly includes a pressure-relief passage 315 and two pressure-relief control switches communicated with the pressure-relief passage 315, when in use, the circulation cleaning container is in a motion state, and is not basically in a horizontal state for a long time, when the 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 opening 311 is inevitably communicated with the cavity 34 through the pressure-relief passage 315, so that the pressure in the cavity 34 can be released, thereby balancing the internal and external pressures of the circulation cleaning container, and effectively reducing the negative effects caused by the imbalance of the pressures in the circulation cleaning container; even when the circulating cleaning container is in a horizontal state, at the moment, the two pressure relief control switches are in the same horizontal line, one of the pressure relief control switches can be flushed away by liquid in the cavity 34 under the action of inertia, so that a pre-pressure relief opening 311 is communicated with the cavity 34 through the pressure relief channel 315, the pressure in the cavity 34 can be released, the internal pressure and the external pressure of the circulating cleaning container are balanced, and negative effects caused by pressure imbalance in the circulating cleaning container are effectively reduced. The pressure relief control switch comprises a body with a cavity, the pre-pressure relief opening 311 is formed in the body and communicated with the cavity, and a movable ball valve 312 and a limiting part 314 for limiting the moving position of the ball valve 312 are arranged in the cavity.

When the car washing device adopts the cleaning roller to continuously clean, in the automatic cleaning process of the cleaning roller, air partially contained in gaps of a scrubbing sponge layer of the cleaning roller enters a cleaning liquid loop along with extruded water during the extrusion of the cleaning roller, so that the loop pressure is increased, the loop liquid conveying efficiency is low, and the pressure accumulated in the cleaning liquid loop can flush the sealing structures at joints, joints and the like in a conveying pipeline to cause the leakage of the cleaning liquid loop seriously affecting the performance of the car washing device.

Specifically, as shown in fig. 3, since the ball valve 312 is freely movable in the cavity, and the two pressure release control switches are disposed on the same horizontal line, when the two pressure release control switches are parallel to the horizontal plane, theoretically, it is possible that both pressure release control switches are in an off state, an on state, or one is in another. Because the pressure increase condition can be generated when the circulating cleaning container is used, and the circulating cleaning container is in a motion state when the circulating cleaning container is used, the two pressure relief control switches cannot be in a horizontal state for a long time at the same time, so that only one of the two pressure relief control switches is in an on state and the other one is in an off state. Thereby ensuring that at least one pre-pressure relief opening 311 is communicated with the outside of the shell 30 through the pressure relief channel 315 and the pressure relief opening 3011 during use, and realizing that the inside and the outside of the cavity are in a pressure balance state.

Specifically, as shown in fig. 4, 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 cavity is provided with an inclined plane 317 for moving the ball valve 312 towards the pre-pressure release opening 311 and a straight horizontal plane 318 for connecting the bottom of the inclined plane 317 with the pre-pressure release opening 311, when the two pressure release control switches are on the same horizontal plane, even if the ball valve 312 makes the pre-pressure release opening 311 non-conductive, the ball valve 312 of one of the pressure release control switches can be flushed away by the liquid in the cavity 34 under the inertia effect, and the ball valve 312 is inevitably easier to leave the closing position of the pre-pressure release opening 311, so that one pre-pressure release opening 311 is inevitably communicated with the cavity 34 through the pressure release channel 315, and thus the pressure in the cavity 34 can be released, thereby balancing the pressure inside and outside the container for cyclic cleaning.

According to the requirement, as shown in fig. 4, the pre-pressure relief opening 311 is provided with an elastic sleeve 313, which can effectively reduce the contact noise generated during movement, and the elastic sleeve 313 is made of elastic materials such as silica gel. The elastic sleeve 313 is in a horn-shaped structure, so that the switching effect can be better.

According to the requirement, as shown in fig. 3 and 5, the circulation cleaning container further comprises a conversion mechanism 33 for converting the recovered liquid into the cleaning liquid, wherein one end of the conversion mechanism 33 far away from the interface mechanism 32 extends to a slope close to the lower shell lifting body 301, so as to increase the surface area of the conversion mechanism 33, the conversion mechanism 33 comprises a cage-shaped support 331 and a separation layer 332 covering the surface of the cage-shaped support 331 and enabling the cage-shaped support 331 to form a relatively independent space, the separation layer is provided with a filter through hole (not shown in the drawings), only one end of the conversion mechanism 33 is provided with an opening, the cage-shaped support 331 is provided with a connecting screw 333 on the outer surface of the opening end of the conversion mechanism 33, and the cage-shaped support 331 is matched with an internal thread (not shown in the drawings) at one end close to the cavity 34 of the interface mechanism 32 through the connecting screw 333, so as to realize the detachable connection of the conversion mechanism 33 on the interface mechanism 32.

Specifically, as shown in fig. 5, 6, and 7, a port (not shown in the drawings) connected to the water inlet pipe 321 is disposed at an end of the interface mechanism near the cavity 34, the water inlet pipe 321 extends to the bottom of the conversion mechanism 33, the sewage flowing back to the cavity 34 is converted into relatively clean water by the conversion mechanism 33, and the clean water is sucked into the interface mechanism 32 through the water inlet pipe 321 and then is transported to the surface of the sponge layer (not shown in the drawings) of the cleaning roller through a pipeline. The length of the inlet pipe 321 should not be too short, which may cause the inlet pipe not to suck clean water when the circulation cleaning container is tilted upwards (as shown in fig. 7) and the liquid level H is too low. The length of inlet tube keeps slightly shorter than the length of shifter 33, just so can guarantee to wash the container slope upwards and the liquid level in circulation and inhale water that the inlet tube can be smooth excessively, the water inlet (the drawing of inlet tube does not mark) sets up at the inlet tube end, be equipped with a plurality of inlet openings (the drawing does not mark) on the inlet tube lateral wall, a plurality of inlet openings spread throughout the length direction and the circumferencial direction at whole inlet tube, the water inlet, certain clearance is all left to the diapire and the lateral wall of inlet opening and shifter 33, in order to ensure that shifter 33 not only leans on the filtering action of isolation layer 332 but also leaves certain space and lets the clear water after the filtration have certain velocity of flow gradual change space in the space, avoid impurity at the water inlet, pile up around the inlet opening. The advantage that a plurality of inlet openings spread over the length direction and the circumferential direction of the whole inlet pipe is: in both the inclined upward (as shown in fig. 7) and inclined downward (as shown in fig. 6) states of the circulation washing container, the water inlet and/or the water inlet hole can suck enough fresh water to enable the whole vehicle washing device provided with the circulation washing container to work normally.

When the circulating cleaning container is used, the circulating cleaning container is in a motion state and basically cannot be in a horizontal state for a long time, so that a pre-pressure-relief opening is inevitably communicated with the pressure-relief channel to form the cavity, the pressure in the cavity can be released, the internal pressure and the external pressure of the circulating cleaning container are balanced, and negative influences caused by imbalance of the internal pressure of the circulating cleaning container are effectively reduced.

When the circulation washing container needs to be changed with water or when a conversion mechanism in the circulation washing container needs to be deeply cleaned, the interface mechanism 32 is separated from the opening at one end of the shell 30 by external force, and then the liquid in the washing container is poured and new liquid is injected again; or, the switching mechanism 33 movably connected to the interface mechanism 32 is further unscrewed, the isolating layer 332 of the switching mechanism 33 is further deeply cleaned and then installed back, and finally the interface mechanism 32 is clamped into the shell 30 by external force, so that the cleaning liquid replacement or the deep cleaning action on the switching mechanism is completed.

The foregoing detailed description of the embodiments of the present application has been presented to illustrate the principles and implementations of the present application, and the description of the embodiments is only intended to facilitate the understanding of the methods and their core concepts of the present application. Meanwhile, according to the idea of the present application, a person skilled in the art may make changes or modifications based on the specific embodiments and the application range of the present application, and all of them belong to the protection scope of the present application.
