Detailed Description
The technical scheme and beneficial effects of the present utility model will be described in detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 3, a pressurizing and draining valve is provided in a toilet tank, and comprises a valve body 1 and a draining assembly 2. Wherein, the valve body 1 comprises a drain seat 11, a fixed seat 12, a fixed gland 13 and a housing 14 from bottom to top. Wherein, the water draining seat 11 is connected with the bottom of the fixed seat 12, and a hollow body is arranged between the water draining seat 11 and the fixed seat 12, and water in the water supply tank freely flows in from the side. The bottom of the drain seat 11 forms a drain outlet 101.
The drain assembly 2 includes a water pump 21, a hydraulic chamber 22, and a piston movement assembly 23. The fixed seat 12 and the fixed gland 13 are buckled to form a containing space, a water pump 21 is arranged on the left side of the containing space, and a hydraulic cavity 22 is arranged on the right side of the containing space, wherein the water pump 21 is a submersible pump. The water pump 21 is provided with a water inlet 211 and a water outlet 212, and the water outlet 212 is communicated with the hydraulic chamber 22 to form a first water flow channel. The main body of the hydraulic cavity 22 is a cup 221 which is vertically communicated and is provided with an opening, the bottom of the cup 221 is connected with the bottom of the fixed seat 12 in a sealing way, the top end of the cup is matched with the fixed gland 13, and the side wall of the cup 221 is provided with a water inlet 2210 which is connected with the water outlet 212 of the water pump 21. The bottom of the fixed seat 12 is provided with a hollow column 121 extending upwards corresponding to the hydraulic chamber 22, and the hollow column 121 is provided with a longitudinal slideway. The housing 14 is provided outside the accommodation space.
The piston motion assembly 23 comprises a piston 231 and a gland 232 linked with the piston 231, the gland 232 comprises an outer cover 2321 and an inner cover 2322 which are sleeved with each other, a silica gel sheet 2323 is clamped between the outer cover 2321 and the inner cover 2322, and the silica gel sheet 2323 is in sealing fit with the drain seat 22. The piston 231 is disposed in the hydraulic chamber 22, and the gland 232 is disposed on the drain port 101 of the drain seat 11. The outer cover 2321 is fixedly connected to the piston 231 through a longitudinal slide on the hollow post 121.
