The end face of the closed end of the mounting seat 104 is further provided with a vent 1045, and when the water inlet and outlet mechanism 10 faces upwards and the pressure regulating function of the pressure release mechanism 30 is lost, the pressure release channel of the internal and external pressure equalization water tank device 1 still has a pressure release channel capable of slightly regulating the gas pressure inside and outside the pressure release water tank device, and when the water inlet and outlet mechanism 10 faces downwards 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 clean water channel through the vent 1045 and then be sent out into a water outlet channel (not shown in the figure) of the cleaner through the clean water output assembly 102. The mounting base 104 and the outer wall of the water tank body 20 are provided with a guide rib (not marked in the figure), and the guide rib is favorable for conveniently clamping the 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 regular symmetrical shapes, so that the water inlet and outlet mechanism can play a role in preventing reverse connection after being provided with the guide rib.

Specifically, the water tank body 20 includes a water tank upper body (not labeled in the drawing) and a water tank lower body (not labeled in the drawing), a sealing connection is realized between the water tank upper body and the water tank lower body, a side surface extending upwards from the bottom of the water tank lower body is an inclined surface 201, an end portion of one side opposite to the water inlet and outlet mechanism 10 on the top end of the inclined surface is provided with an inner concave clamping portion (not labeled in the drawing) which is convenient to install and fix, and an inner concave clamping groove 202 is arranged on the clamping portion. When the water tank 1 is fixed, corresponding buckles on the cleaner can be buckled in the clamping grooves 202 of the clamping parts, and when the water tank 1 needs to be taken out, the water tank 1 can be taken out by loosening the corresponding buckles. As a further development, the tank upper body and the tank lower body are connected in a sealing manner by means of an ultrasonic weld (not shown).

As a further improved embodiment, the upper water tank body and the lower water tank body are in sealing connection through a process of two-time injection molding.

As a further improved embodiment, the upper water tank body and the lower water tank body are in sealing connection through a direct bonding process.

As a further improved embodiment, the upper water tank body and the lower water tank body are of an integrated structure, and a horizontal step surface 203 is arranged between the upper water tank body and the lower water tank body. The tank upper body and the tank lower body are only part names taken for convenience in describing different portions of the tank body 20 in the up-down height direction.

Specifically, as shown in fig. 10, when the water inlet/outlet mechanism 10 of the water tank 1 is inclined downward, a part of the pressure release mechanism 30 is located above the liquid level H on a side away from the water inlet/outlet mechanism 10, and the water tank 1 still has the capability of releasing pressure to the outside of the pressure release water tank device and also has the capability of continuously outputting clear water to the outside 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 1045 of the water inlet and outlet mechanism 10 is lower than the liquid level H, and is only a very tiny bypass branch of the water outlet channel, and the bypass branch of the water inlet 1045 can realize the effect of "discharging water outwards" under the pressure of the liquid level H. Meanwhile, the water tank 1 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 water tank 1.

Specifically, as shown in fig. 11, when the water inlet/outlet mechanism 10 of the water tank 1 is inclined upward, a part of the pressure release mechanism 30 is located above the liquid level H on a side close to the water inlet/outlet mechanism 10, at this time, the opening of the water suction pipe 106 is lower than the liquid level H, and under the combined action of the water pressure and the air pressure, the pressure is directly released to the outside of the water tank 1 through the pressure release mechanism 30 and along the pressure release pipeline. Meanwhile, the vent 1045 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, the vent 1045 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 1045 is arranged in front of the vent 1045, and in short, the bypass branch of the vent 1045 communicated with the external atmosphere can realize the effect of ventilation and water impermeability. At this time, the bypass branch of the vent 1045, which is open to 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 tank 1, and the water suction pipe 106 is always provided with a water inlet and/or a water suction hole (not labeled in the drawing) below the liquid level H, the clear water output assembly can continuously output clear water outwards. The water tank 1 of the cleaner used in this posture has the capability of discharging pressure to the outside of the water tank and the capability of continuously outputting clear water to the outside. Naturally, when the liquid level H is lower than the water inlet opening of the water suction pipe 106, the water tank 1 cannot continuously output clear water outwards, and the user is reminded to add clear water to the water tank 1 by himself so as to continue using the cleaner.
