Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure water dischargers, and more specifically, to a negative pressure water discharger which is convenient for replacing a filter element. Background Art

[0002] A negative pressure drain is an automatic control system used in drainage systems that automatically opens a drain valve to reduce negative pressure when system pressure falls below a set value. This type of device is primarily used to ensure the proper functioning of drainage systems, playing an essential role in systems such as coal mine gas extraction. During use, existing negative pressure drains require an internal filter to filter impurities from the accumulated water. However, when excessive impurities accumulate on the filter, the user must regularly open the drain to drain the impurities, which increases labor costs and is also time-consuming.

[0003] After searching, the Chinese patent with announcement number CN219733461U discloses a negative pressure water discharger with a filter. The scraper can be driven to move by the handle to scrape off impurities. The overall structure is relatively simple and very convenient to use. It also improves the practicality of the negative pressure water discharger equipment. The impurities on the filter can be collected through the collection box. When the collection box is full of impurities, it can be removed from the fixed frame by pulling the collection box, and then the impurities in the collection box can be poured out and the collection box can be reinstalled. The overall structure is relatively simple and very convenient to use. It also improves the practicality of the negative pressure water discharger equipment.

[0004] When the above-mentioned negative pressure water discharger is in use, accumulated water can enter the filter box through the water inlet, and the filter net can filter the accumulated water. The collection box can be removed from the fixed frame by pulling it. However, when removing the collection box, it is inconvenient to seal the water inlet on the top of the filter box, and the use effect is poor. Utility Model Content

[0030] Furthermore, a through groove is provided on the front side of the filter box 4, and the through groove is located at the top of the U-shaped mesh plate 7. A handle 506 is movably provided on the top of the filter box 4, and the bottom end of the handle 506 is fixedly connected to the screw rod 501. An activated carbon plate 8 is movably provided inside the U-shaped mesh plate 7, and the top of the activated carbon plate 8 is in contact with the baffle 503. The negative pressure water discharger body 1 is fixedly connected to the water outlet pipe 2, and the top of the filter box 4 is fixedly connected to the water inlet pipe 3.

[0031] Furthermore, a limiting assembly is provided on the screw rod 501, and the limiting assembly includes an extrusion plate 507 and a rubber composite plate 6.

The extrusion plate 507 is movably sleeved on the screw rod 501.

[0032] Among them, the extrusion plate 507 is rotated and moved on the screw rod 501. Since the friction between the extrusion plate 507 and the rubber composite plate 6 is large, when the extrusion plate 507 contacts the rubber composite plate 6, the screw rod 501 can be limited. Similarly, the extrusion plate 507 is reversed and moved away from the rubber composite plate 6, thereby releasing the limit on the screw rod 501. The structure is simple and easy to use.

[0033] The method of using this embodiment is:

[0034] When in use, the accumulated water enters the filter box 4 through the water inlet pipe 3, the U-shaped mesh plate 7 filters the accumulated water, and finally the accumulated water is discharged through the water outlet pipe 2 on the negative pressure water discharger body 1, forming a complete waterway. The water guide bucket 9 can guide the accumulated water, and quickly turning the handle 506 can drive the screw rod 501 to rotate. Since the screw rod 501 is threadedly connected to the baffle 503, the limit rod 502 limits the rotation of the baffle 503, so the screw rod 501 can drive the baffle 503 to move upward, thereby driving the second gasket 505 to move upward, and making the second gasket 505 sleeved on the water guide bucket 9, through the second gasket 505 and the baffle 5 03 prevents the accumulated water from flowing out of the water guide bucket 9, and at the same time, the first gasket 504 drives the U-shaped mesh plate 7 to move upward, and finally cleans the impurities on the U-shaped mesh plate 7 through the through groove. Similarly, the reversing handle 506 can drive the baffle 503 and the first gasket 504 to move downward, and the baffle 503 and the first gasket 504 prevent the accumulated water from flowing out through the through groove. The operation is simple and the use effect is good. The activated carbon plate 8 is placed in the U-shaped mesh plate 7, and the baffle 503 limits the activated carbon plate 8. The activated carbon plate 8 can be used to purify and filter the accumulated water. Similarly, the activated carbon plate 8 can be quickly replaced, the operation is simple, and it is easy to replace the filter element.
