One end of the water inlet and outlet mechanism bottom shell 104 is open, the open end is sleeved with the interface terminal 101, the other end is closed, but the closed end face is provided with through holes which communicate with the clean water output assembly 102 and the sewage access assembly 103, among them, a water suction pipe interface 1043 is outwardly extended on the through hole of the clean water output assembly 102 provided on the closed end face of the water inlet and outlet mechanism bottom shell 104, a filter assembly connecting port 1042 is outwardly extended on the closed end face of the water inlet and outlet mechanism bottom shell 104 around the water suction pipe interface 1043, the inner wall of the filter assembly connecting port 1042 is provided with threads (not marked in the figure), the inner threads are coupled with the outer threads (not marked in the figure) of the filter assembly connecting port 401 of an open end of a cylindrical filter assembly 40 for detachable connection, the peripheral wall and the bottom wall of the filter assembly 40 are provided with a plurality of hollow structures (not marked in the figure), and the outer surface is covered with a filter screen (not marked in the figure).A water suction pipe 106 is sleeved on the water suction pipe interface 1043 and extends to an area close to the bottom wall of the filter assembly 40, so that the filtered water in the filter assembly 40 in the circulating water tank device 1 can still be sucked by the water suction pipe 106 when the water inlet and outlet mechanism 10 is upward, and the state of being able to be sucked is maintained until the water level of the filtered water in the filter assembly 40 is lower than the lowest opening (not marked in the figure) of the water suction pipe 106. A sewage return port 1045 in communication with the sewage inlet assembly 103 is further arranged on the closed end surface of the bottom shell 104 of the water inlet and outlet mechanism outside the filter assembly connecting port 1042, and the cleaned sewage of the cleaner passes through the return channel 1034, then passes through the sewage return port 1045, and then enters the first cavity X in the circulating water tank device 1. The sewage is filtered by the filter assembly 40, then is sucked into the water outlet channel 1024 by the water suction pipe 106, and finally is sent out to the water outlet passage (not shown in the figure) of the cleaner by the clean water output assembly 102. A water inlet and outlet mechanism bottom shell vent hole 1041 is further arranged in the filter assembly connecting port 1042 on the closed end surface of the bottom shell 104 of the water inlet and outlet mechanism. When the water inlet and outlet mechanism 10 is upward and the pressure regulating function of the pressure relief mechanism 205 is lost, the circulating water tank device 1 still has a pressure relief channel to slightly adjust the gas pressure inside and outside the circulating water tank device. When the water inlet and outlet mechanism 10 is downward and the water level of the water in the filter assembly 40 is lower than the highest opening of the water suction pipe 106, water can still enter the water outlet channel through the vent hole 1041 and then be sent out to the water outlet passage (not shown in the figure) of the cleaner by the clean water output assembly 102. A guide rib 1046 is arranged on the outer wall of the water inlet and outlet mechanism bottom shell 104 matched with the water tank body 20. The guide rib 1046 helps the installed water inlet and outlet mechanism 10 to be conveniently clamped into the water tank body 20. Since the outer wall matched with the water tank body 20 is regularly symmetrical, the guide rib 1046 can also prevent reverse connection.

[0083] Specifically, as Figure 5 、 Figure 6 、 Figure 7As shown, the circulating water tank device 1 includes an upper body 206 and a lower body 207. The upper body 206 and the lower body 207 are connected by a sealed connection. The bottom of the lower body 207 extends upwards on a sloped side. The top of the slope, opposite to the water inlet / outlet mechanism 10, has a concave snap-fit ​​part 201 for easy installation and fixing. This snap-fit ​​part has a concave snap-fit ​​groove 202. When fixing the circulating water tank device 1, the corresponding buckle on the cleaner can be engaged in the snap-fit ​​groove 202 of the snap-fit ​​part 201. When it is necessary to remove the circulating water tank device 1, the corresponding buckle can be released to remove the circulating water tank device 1.

[0084] As a further improved implementation, the upper body 206 and the lower body 207 of the water tank are sealed together by an ultrasonic welding layer (not shown in the figure).

[0085] As a further improved implementation, the upper body 206 and the lower body 207 of the water tank are sealed together by a secondary injection molding process.

[0086] As a further improved implementation, the upper body 206 and the lower body 207 of the water tank are sealed together by a direct bonding process.

[0087] Specifically, such as Figure 14 As shown, when the inlet / outlet mechanism 10 of the circulating water tank device 1 is tilted downwards, a portion of the pressure relief mechanism 205 on the side away from the inlet / outlet mechanism 10 is above the liquid surface H. Regardless of whether the opening of the suction pipe 106 is always below the liquid surface H, the circulating water tank device 1 still has the ability to release pressure to the outside of the circulating water tank device and also has the ability to continuously output clean water. When the inlet of the suction pipe 106 is below the liquid surface H, the suction pipe 106 can naturally achieve the function of "discharging water". When the inlet of the suction pipe 106 is above the liquid surface H, the vent 1041 of the inlet / outlet mechanism 10 is lower than the liquid surface H and is only a very small bypass branch of the outlet channel 1024. The bypass branch of the vent 1041 can achieve the function of "discharging water" under the pressure of the liquid surface H. At the same time, due to the pressure difference between the inside and outside of the circulating water tank device 1, the circulating water tank device of the cleaner used in this manner has the ability to supply water to the outside and release pressure to the outside.

[0088] Specifically, such as Figure 15As shown, when the water inlet and outlet mechanism 10 of the circulating water tank device 1 is tilted upward, a part of the pressure relief mechanism 205 is above the liquid level H on the side close to the water inlet and outlet mechanism 10. At this time, the opening of the water suction pipe 106 is below the liquid level H. Under the combined action of water pressure and air pressure, the pressure passes through the pressure relief mechanism 205 and directly acts on the exhaust nozzle 203 of the circulating water tank device 1 along the pressure relief pipeline. The exhaust nozzle 203 can be a one-way valve. Due to the one-way conduction of the one-way valve, the one-way valve is compactly closed under the combined action of water pressure and air pressure. The air vent hole 1041 of the water inlet and outlet mechanism 10 is above the liquid level H and is only a very small bypass branch of the water outlet channel 1024. The air vent hole 1041 is in communication with the outside atmosphere. The air vent hole 1041 is provided with a bypass branch of the air vent hole 1041 before the bypass branch of the air vent hole 1041 is blocked by the water flow. In short, the bypass branch of the air vent hole 1041 in communication with the outside atmosphere can achieve the effect of "air permeability but water impermeability". At this time, the bypass branch of the air vent hole 1041 in communication with the outside atmosphere has the ability to release pressure outside the water supply device. At the same time, due to the pressure difference between the inside and outside of the water supply device and the water inlet and / or water suction hole below the liquid level H of the water suction pipe 106, the clean water output assembly can continuously output clean water outside. The water supply device of the car washing device used in this posture has the ability to release pressure outside the water supply device and the ability to continuously output clean water outside. Of course, when the liquid level H is lower than the water inlet opening of the water suction pipe 106, the circulating water tank device 1 cannot continuously output clean water outside. At this time, the user is reminded to add clean water to the circulating water tank device 1 for continuous use of the cleaner.

[0089] As shown in the drawings, Figure 16 The present application provides another embodiment of an electrically powered car washing tool.

[0090] Different from the foregoing embodiment, the second pressure relief connector 2056 is changed into a tee connector, and the original tee connector 2057 is omitted. The horizontal end interface of the first pressure relief connector 2055 and the second pressure relief connector 2056 is directly connected with the pressure relief hose 60, and the other vertical end interface of the second pressure relief connector 2056 is connected with the exhaust nozzle 203 through the pressure relief hose 60. The exhaust nozzle 203 is arranged close to the tail of the circulating water tank device 1. This design can make the filter assembly 40 have more space to arrange the filter screen to increase the filtering effect without increasing the diameter of the filter assembly 40, and can make the water suction pipe 106 extend longer to reduce the situation that the residual clean water in the circulating water tank device 1 cannot be used when the water inlet and outlet mechanism 10 is tilted upward.

[0091] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
