The end face of the closed end of the water inlet/outlet mechanism bottom shell 104 is further provided with a water inlet/outlet mechanism bottom shell vent 1041 inside the filter assembly connector 1042, and when the water inlet/outlet mechanism 10 faces upward and the pressure release mechanism 205 loses the pressure regulating function, the pressure release water tank device 1 still has a pressure release channel for slightly regulating the gas pressure inside and outside the pressure release water tank device, and when the water inlet/outlet mechanism 10 faces 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, the water still can enter the water outlet channel through the vent 1041 and then be sent out into the water outlet channel (not shown in the figure) of the cleaner through the clean water output assembly 102. The water inlet and outlet mechanism bottom shell 104 and the outer wall of the water tank body 20 are provided with a guide rib 1046, and the guide rib 1046 is beneficial to the convenient clamping of the installed water inlet and outlet mechanism 10 into the water tank body 20, and the water inlet and outlet mechanism 10 and the outer wall of the water tank body 20 are in a regular symmetrical shape, so that the water inlet and outlet mechanism can play a role in preventing reverse connection after the guide rib 1046 is arranged.

Specifically, as shown in fig. 2, 3 and 4, the pressure relief water tank device 1 includes a water tank upper body 206 and a water tank lower body 207, the water tank upper body 206 and the water tank lower body 207 are connected in a sealing manner, a side surface extending upwards from the bottom of the water tank lower body 207 is an inclined surface, an end portion of one side of the top end of the inclined surface opposite to the water inlet and outlet mechanism 10 is provided with an inner concave clamping portion 201 convenient to mount and fix, and the clamping portion is provided with an inner concave clamping groove 202. When the pressure relief water tank device 1 is fixed, corresponding buckles on the cleaner can be buckled in the clamping grooves 202 of the clamping parts 201, and when the pressure relief water tank device 1 needs to be taken out, the pressure relief water tank device 1 can be taken out by loosening the corresponding buckles. 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 upper tank body 206 and the lower tank body 207 are hermetically connected by a two-shot molding process.

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

Specifically, as shown in fig. 11, when the water inlet/outlet mechanism 10 of the pressure relief water tank device 1 is inclined downward, a part of the pressure relief mechanism 205 is located above the liquid level H on a side away from the water inlet/outlet mechanism 10, and the pressure relief water tank device 1 still has the capability of releasing pressure to the outside of the pressure relief water tank device and also has the capability of continuously and outwardly outputting clean water no matter whether the opening of the water suction pipe 106 is always below the liquid level H. When the water inlet of the water suction pipe 106 is positioned below the liquid level H, the natural water suction pipe 106 can realize the effect of 'discharging water outwards'. When the water inlet of the water suction pipe 106 is above the liquid level H, the air vent 1041 of the water inlet and outlet mechanism 10 is lower than the liquid level H, and is only a very small bypass branch of the water outlet channel 1024, and the bypass branch of the water inlet 1041 can realize the effect of "discharging water outwards" under the pressure of the liquid level H. Meanwhile, the pressure relief water tank device of the cleaner used in the posture has the capability of supplying water and discharging pressure outwards due to the pressure difference between the inside and the outside of the pressure relief water tank device 1.

Specifically, as shown in fig. 12, when the water inlet and outlet mechanism 10 of the pressure relief water tank device 1 is inclined upwards, a part of the pressure relief mechanism 205 is located above the liquid level H on a side close to the water inlet and outlet mechanism 10, at this time, the opening of the water suction pipe 106 is lower than the liquid level H, under the combined action of the water pressure and the air pressure, the pressure directly acts on the air outlet nozzle 203 of the pressure relief water tank device 1 through the pressure relief mechanism 205 and along the pressure relief pipeline, and the air outlet nozzle 203 may be specifically a one-way valve, and the one-way valve is compacted and closed under the combined action of the water pressure and the air pressure due to the one-way conduction of the one-way valve. The vent 1041 of the water inlet and outlet mechanism 10 is higher than the liquid level H, and is only a very tiny bypass branch of the water outlet channel 1024, the vent 1041 is communicated with the external atmosphere, a bypass structure (not shown in the drawing) for blocking the bypass branch of the water flow to the vent 1041 is arranged in front of the vent 1041, and in short, the bypass branch of the vent 1041 communicated with the external atmosphere can realize the effect of ventilation and water impermeability. At this time, the bypass branch of the vent 1041, which communicates with the outside atmosphere, has the capability of releasing pressure to the outside of the water supply device. Meanwhile, as the pressure difference exists between the inside and the outside of the water supply device, and the water suction pipe 106 is always provided with a water inlet and/or a water suction hole below the liquid level H, the clear water output assembly can continuously output clear 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 and outwards outputting clear water. Naturally, when the liquid level H is lower than the water inlet opening of the water suction pipe 106, the pressure release water tank device 1 cannot continuously output clear water outwards, and the user is reminded to add clear water into the pressure release water tank device 1 by himself so as to continue using the cleaner.

As shown in FIG. 13, the present invention provides another embodiment of a pressure relief water tank assembly suitable for use with a cleaning implement.

Unlike the previous embodiments, the second pressure relief joint 2056 is modified to be a three-way joint, the original three-way joint 2057 is omitted, the horizontal end of the first pressure relief joint 2055 and the second pressure relief joint 2056 is directly connected to the pressure relief hose 60, and the other vertical end of the second pressure relief joint 2056 is connected to the exhaust nozzle 203 through the pressure relief hose 60. The exhaust nozzle 203 is disposed near the tail of the pressure relief water tank device 1, so that the design can make the filter assembly 40 have more space to set the filter screen to increase the filtering effect on the basis of not increasing the diameter of the filter assembly, and at the same time, the water suction pipe 106 can extend longer, so as to reduce the occurrence of the residual unusable condition in the pressure relief water tank device 1 when the water inlet and outlet mechanism 10 is inclined upwards.

The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the 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: the technical solutions described in the foregoing embodiments may be modified or some technical features may be replaced with other technical solutions, which may not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
