As shown in fig. 6 to 10, the pressure to be released in the water tank enters the pressure regulating filter device 3 through the filter screens 304 arranged on two sides and the bottom surface of the framework of the filter assembly 30, then continues to enter the pressure regulating tank through the pressure regulating notches 318, one of the two pressure regulating balls 33 seals the pressure regulating ports (3553, 3563) of the corresponding pressure regulating ball sealing members (355, 356), the other pressure regulating ball 33 opens the pre-regulating port of the corresponding pressure regulating ball sealing member, after the pressure to be released passes through the pressure regulating ball 33 corresponding to the pressure regulating port, the pressure is continuously introduced into the pressure regulating rear channel inlet 3172 along the notch on the side wall of the pressure regulating tank, then flows along the pressure regulating channel 317 to the exhaust port 302, and then is discharged out of the water tank through the exhaust port 103 of the water tank bayonet assembly 1. The pressure regulating notch 318, the pressure regulating groove and the pressure regulating back section channel together form a complete pressure regulating channel.

As a further modified embodiment, as shown in fig. 4, 8 and 10, a check valve 34 may be further provided in the exhaust valve mounting step 3171. Specifically, the check valve 34 may be an exhaust duckbill valve as shown in fig. 4 and 10, and by utilizing the unidirectional conduction characteristic of the check valve 34, the reverse filling of the pressure regulating tank through the pressure regulating rear-stage channel 317 by the external pressure of the water tank can be effectively prevented.

As a further improved embodiment, as shown in fig. 6 and 7, when the water tank body set 2 is in a moving state and is not in a horizontal state basically for a long time, when two pressure regulating balls 33 of the pressure regulating filter device 3 are not in the same horizontal line, one of the pressure regulating balls 33 is in a state of closing the pressure regulating ports (3553, 3563) of the corresponding pressure regulating ball sealing members (355, 356), so that one pre-regulating port 318 is necessarily communicated with the containing cavity of the water tank through the pressure regulating channel 317, and the pressure in the containing cavity can be released, thereby balancing the pressure inside and outside the water tank and effectively reducing negative effects caused by unbalanced pressure in the water tank; even when the circulation cleaning container is in a horizontal state, the two pressure regulating balls 33 are in the same horizontal line, one pressure regulating ball 33 can be flushed away by the liquid in the containing cavity under the inertia effect, so that one pre-pressure opening 318 is necessarily communicated with the containing cavity through the pressure regulating channel 317, the pressure in the containing cavity can be released, the pressure inside and outside the circulation cleaning container is balanced, and the negative influence caused by the unbalance of the pressure in the circulation cleaning container is effectively reduced.

Specifically, as shown in fig. 6, 7, and 8, since the pressure regulating balls 33 are freely movable in the pressure regulating grooves, when the two pressure regulating balls 33 are on the same horizontal line and the pressure regulating grooves are parallel to the horizontal plane, it is theoretically possible that both the pressure regulating balls 33 are in a state of closing the pressure regulating ports (3553, 3563) of the corresponding pressure regulating ball sealing members (355, 356), a state of not closing the pressure regulating ports (3553, 3563) of any of the corresponding pressure regulating ball sealing members (355, 356), and an open state of one of the other. Since the water tank is in a moving state when in use, and the two pressure regulating balls 33 cannot be in a horizontal state for a long time at the same time, only one of the two pressure regulating balls 33 is in a state of closing the pressure regulating ports (3553, 3563) of the corresponding pressure regulating ball sealing members (355, 356), and the other is in a state of not closing the pressure regulating ports (3553, 3563) of any one of the corresponding pressure regulating ball sealing members (355, 356).

When two or more pressure regulating balls 33 are not in the same horizontal plane, when two or more pressure regulating balls 33 are mutually accumulated and overlapped, when the pressure born by the pre-regulating opening 318 can be larger than the component of the gravity sum of the two or more pressure regulating balls 33 in the direction of the inclined plane of the pressure regulating groove, the pressure can flush out two or more pressure regulating ball groups mutually accumulated and overlapped, so that one pre-regulating opening 318 is communicated with the water tank through the pressure regulating channel 317, and the pressure in the water tank can be released, thereby balancing the internal pressure and the external pressure of the water tank.

Users use cleaners in different areas, and the difference in the ability of the water tank of the cleaner arrangement to adjust the difference in air pressure inside and outside the water tank is often caused by the difference in climate conditions in the different areas. In order to enable the user to conveniently adjust the internal and external pressure difference of the water tank according to different application scenes, different numbers of pressure adjusting balls 33 are arranged in the pressure adjusting channel. The pressure regulating principle of the pressure regulating filter device 3 is as described above, the more the number of pressure regulating balls 33 are arranged in the pressure regulating channel, the greater the pressure of the pressure regulating ball group is flushed by the pre-regulating port 318, so that the user can select the number of the pressure regulating balls 33 placed in the pressure regulating channel by himself, and the ability of the user to automatically select the internal and external pressure of the water tank is realized.

As a further improved embodiment, as shown in fig. 11, the sealing member 35 may effectively reduce noise generated by the impact of the pressure regulating ball 33 during movement, and the sealing member 35 may be made of an elastic material such as silicone rubber. The sealing member 35 is parallel to the pressure regulating groove and closes the pressure regulating groove from the top opening of the pressure regulating groove, two ends of the sealing member 35 are provided with a right pressure regulating ball sealing member 355 and a left pressure regulating ball sealing member 356 which are matched with the pressure regulating ball 33, the end part of the right pressure regulating ball sealing member 355, which is away from the pressure regulating ball 33, is provided with a right pressure regulating opening 3553 communicated with the nearest one pre-pressure regulating notch 318, the end part of the left pressure regulating ball sealing member 356, which is away from the pressure regulating ball 33, is provided with a left pressure regulating opening 3563 communicated with the nearest one pre-pressure regulating notch 318, and the pressure regulating ball 33 can be used for blocking the right pressure regulating opening 3553 and the left pressure regulating opening 3563 under the action of gravity so as to block the pre-pressure regulating notch 318, and can only move in the pressure regulating groove between the right pressure regulating ball sealing member 355 and the left pressure regulating ball sealing member 356. The pressure regulating ball 33, the right pressure regulating ball sealing member 355, the left pressure regulating ball sealing member 356, and the pressure regulating groove together form a complete pressure regulating control assembly (not shown) having two sets of independent pressure regulating control switches (not shown).
