The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The invention is described in further detail below with reference to the accompanying drawings:

as shown in figures 1-3, the utility model provides a water tank respirator, include: a housing 10, a filter 20, and a water tank 30; wherein,

the utility model discloses a casing 10 is top confined casing, and the lower open-end of casing 10 can weld fixedly or cover on water tank 30's upper cover through the connecting piece bolt installation.

The utility model discloses be equipped with filter 20 in the casing 10, filter 20 excessively filters the air of business turn over water tank. After the housing 10 is mounted on the water tank 30, the filter 20 is placed in the housing 10 and the bottom of the filter is vertically placed on the upper cover of the water tank 30; preferably, the bottom of the filter 20 is higher than the upper cover of the water tank 30, so as to prevent the filter 20 from being directly immersed on the filter 20 after entering water through the casing, and the filtering performance of the filter 20 is not affected; in order to achieve the above function, the utility model discloses can be on water tank 30 corresponding filter's position welding or bolted mounting have support 40, after casing 10 welded mounting was on water tank 30, filter 20 in the casing 10 was arranged in on support 40.

The utility model discloses be equipped with breather 11 on the lower part lateral wall of casing 10, the upper portion lateral wall of casing 10 is opened there is the air vent, and the air vent passes through breathing channel 12 and water tank 30's respiration window 31 fixed connection. Wherein, as shown in fig. 3 and 4, in order to fix the filter 20 in the casing 10 and to realize that the air between the breathing hole 11 and the breathing passage 12 in the casing 10 circulates and passes through the filter 20, the casing 10 of the present invention is horizontally provided with a spacing ring 13 on the inner wall below the breathing hole, the spacing ring 13 is matched with the outer wall of the filter 20 to realize the upper end spacing of the filter 20 and prevent the filter 20 from toppling over; when the water level in the water tank 30 is lowered, the air pressure in the water tank is lowered, and at this time, the external air enters the lower space (the space below the limit ring 13) of the housing 10 through the breathing hole 11, is filtered by the filter 20, enters the upper space (the space above the limit ring 13) of the housing 10, and enters the water tank 30 through the breathing passage 12 and the breathing window 31. In contrast, when the water level in the water tank 30 rises, the water tank air pressure rises, and at this time, the air in the water tank 30 enters the upper space of the housing 10 through the breathing window 31, the breathing passage 12, and is filtered by the filter 20 to enter the lower space of the housing 10, and then is discharged through the breathing hole 11.
