A vent hole 1041 is further arranged in the filter assembly sealing brim 1042 on the end face of the closed end of the mounting seat 104, the vent hole 1041 can enable the water inlet and outlet mechanism 10 to face upward, when the pressure relief mechanism 30 loses the pressure regulating function, the internal and external pressure equalization water tank device 1 still has a pressure relief channel capable of slightly regulating the air pressure inside and outside the pressure relief water tank device, when the water inlet and 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 clear water channel through the vent hole 1041 and then is sent out to a water outlet passage (not marked in the figure) of the cleaner through the clear water output assembly 102. The mounting seat 104 with be equipped with a direction muscle 1046 on the outer wall of water tank body 20 complex, this direction muscle 1046 helps the convenient card of the business turn over water mechanism 10 of installation to go into the water tank body 20, because business turn over water mechanism 10 with water tank body 20 complex outer wall is the shape of regular symmetry, has set up can also play the effect of preventing joining conversely behind the direction muscle 1046.
Specifically, the water tank body 20 includes an upper water tank body (not shown in the drawings) and a lower water tank body (not shown in the drawings), the upper water tank body and the lower water tank body are connected in a sealing manner, a side surface of the lower water tank body extending upward from the bottom of the lower water tank body is an inclined surface (not shown in the drawings), an inner concave clamping portion 201 convenient for installation and fixation is arranged at the top end of the inclined surface and at the end of one side opposite to the water inlet and outlet mechanism 10, and an inner concave clamping groove 202 is formed in the clamping portion. When the internal and external pressure equalization water tank device 1 is fixed, the corresponding buckle on the cleaner can be buckled in the clamping groove 202 of the clamping part 201, and the internal and external pressure equalization water tank device 1 needs to be taken out by loosening the corresponding buckle, so that the internal and external pressure equalization water tank device 1 can be taken out. In a further improved embodiment, the tank upper body and the tank lower body are hermetically connected by an ultrasonic welding layer (not shown).
As a further improved embodiment, the upper water tank body and the lower water tank body are hermetically connected through a secondary injection molding process.
As a further improved embodiment, the upper tank body and the lower tank body are hermetically connected through a direct bonding process.
Specifically, as shown in fig. 8, when the water inlet and outlet mechanism 10 of the 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 1041 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 1024, and the bypass branch of the water through hole 1041 can realize the effect of "discharging water outwards" under the pressure of the liquid level H. Meanwhile, since the inside and outside pressure equalizing water tank device 1 has a pressure difference between the inside and outside, the inside and outside pressure equalizing water tank device 1 of the cleaner used in such a posture has the capability of supplying and discharging pressure to the outside at the same time.
Specifically, as shown in fig. 9, when the water inlet and outlet mechanism 10 of the internal and external pressure-equalizing 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 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 internal and external pressure-equalizing water tank device 1 through the pressure relief mechanism 30 and along a pressure relief pipeline. Meanwhile, the vent hole 1041 of the water inlet and outlet mechanism 10 is higher than the liquid level H and is only a very small bypass branch of the water outlet channel 1024, the vent hole 1041 is communicated with the outside atmosphere, a bypass structure (not shown in the drawings) for blocking the water flow from the bypass branch of the vent hole 1041 is arranged in front of the vent hole 1041, and simply, the bypass branch of the vent hole 1041 communicated with the outside atmosphere can realize the efficacy of "air permeability and water impermeability". At this time, the bypass branch of the vent hole 1041 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 internal and external pressure equalizing water tank device 1, and the water inlet and/or the water absorbing hole (not shown in the figure) which is positioned below the liquid level H is always arranged on the water absorbing pipe 106, the clean water output assembly can continuously output the clean water outwards. The internal and external pressure equalizing water tank device 1 of the cleaner used in such a 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 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 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 new technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be appreciated by those skilled in the art that: it is to be understood that modifications may be made to the above-described 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.
