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

Specifically, as shown in fig. 7, when the water inlet and outlet mechanism 10 of the novel internal and external pressure equalizing water tank device 1 is inclined downward, a part of the pressure relief mechanism 30 is located above the liquid level H on the side away from the water inlet and outlet mechanism 10, and no matter whether the opening of the suction pipe 106 is always located below the liquid level H, the pressure relieving water tank device 1 still has the capability of releasing pressure to the outside of the pressure relieving water tank device and also has the capability of continuously outputting clean water to the outside. When the water inlet of the suction pipe 106 is below the liquid level H, the natural suction pipe 106 can realize the effect of discharging water outwards. When the water inlet of the suction pipe 106 is above the liquid level H, the vent hole 1045 of the water inlet and outlet mechanism 10 is lower than the liquid level H and is only a tiny bypass branch of the water outlet channel, and the bypass branch of the water through hole 1045 can realize the effect of "discharging water outwards" under the pressure of the liquid level H. Meanwhile, because the pressure difference exists between the inside and the outside of the novel internal and external pressure equalization water tank device 1, the novel internal and external pressure equalization water tank device 1 of the cleaner used in the posture has the capacity of supplying water and releasing pressure outwards at the same time.

Specifically, as shown in fig. 8, when the water inlet and outlet mechanism 10 of the novel internal and external pressure equalization water tank device 1 is inclined upward, a part of the pressure relief mechanism 30 is located above the liquid level H at 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, and under the combined action of water pressure and air pressure, the pressure is directly released out of the novel internal and external pressure equalization water tank device 1 through the pressure relief mechanism 30 and along the pressure relief pipeline. Meanwhile, the vent hole 1045 of the water inlet and outlet mechanism 10 is higher than the liquid level H and is only a tiny bypass branch of the water outlet channel, the vent hole 1045 is communicated with the outside atmosphere, a bypass structure (not shown in the drawing) for blocking the water flow from flowing to the bypass branch of the vent hole 1045 is arranged in front of the vent hole 1045, and in a simple manner, the bypass branch of the vent hole 1045 communicated with the outside atmosphere can achieve the effects of air permeability and water impermeability. At this time, the bypass branch of the vent hole 1045 communicating with the outside atmosphere has the capability of releasing the pressure to the outside of the water supply apparatus. Meanwhile, because the pressure difference exists between the inside and the outside of the novel internal and external pressure equalizing water tank device 1, and the water suction pipe 106 is always provided with a water inlet and/or a water suction hole (not shown in the drawing) which is positioned below the liquid level H, the clean water output assembly can continuously output clean water outwards. The novel internal and external pressure balanced water tank device 1 of the cleaner used in the posture has the capability of releasing pressure to the outside of the water tank and the capability of continuously outputting clean water to the outside. Of course, when the liquid level H is lower than the water inlet opening of the suction pipe 106, naturally, the novel internal and external pressure equalization water tank device 1 cannot continuously output clean water to the outside, and at this time, the user is reminded to add clean water to the novel internal and external pressure equalization water tank device 1 by himself so as to continue to use the cleaner.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
