[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] As Figures 1 to 9 shown, the present invention discloses an integrated boost-assisted drainage valve, including: a housing, a boost pump 200, a drainage device and a drainage base 500; the boost pump 200 and the drainage device are installed in the housing, the drainage base 500 is installed below the housing, a first through hole is provided on the housing, the water inlet of the boost pump 200 is connected to the water inlet pipe 210, the water inlet pipe 210 passes through the first through hole, and the water inlet end of the water inlet pipe 210 is arranged below the liquid level. The boost pump 200 is provided with a second water outlet 230 and a first water outlet 220. The second water outlet 230 communicates with the drainage device, and the first water outlet 220 communicates with the drainage base 500.

[0021] The housing includes an upper housing 100 and a lower housing 400, and the upper housing 100 is buckled on the lower housing 400; two guide plates 410 are provided on the side surface of the lower housing 400, and the guide plates 410 are arranged on both sides of the housing. Two guide grooves 150 are provided on the upper housing 100 and are matched with the guide plates 410. In this embodiment, when the upper housing 100 and the lower housing 400 are installed, the cooperation between the guide plate 410 and the guide groove 150 can guide the upper housing 100, facilitating the alignment and buckling of the buckles on the upper housing 100 and the lower housing 400. In other embodiments, the number of the guide plates 410 and the guide grooves 150 can be three groups or more.

[0022] A first U-shaped groove 140 is formed in the upper housing 100. A support plate 430 is fixedly connected to one side of the lower housing 400 close to the baffle 420. A second U-shaped groove 431 is formed in the support plate 430. When the upper housing 100 and the lower housing 400 are engaged with each other, the arc portions of the first U-shaped groove 140 and the second U-shaped groove 431 intersect to form a first through hole.

[0023] A first mounting seat for fixing the boosting pump 200 is provided on the lower housing 400. The boosting pump 200 is horizontally installed in the first mounting seat. The first mounting seat is composed of a plurality of spaced baffles 420. Mounting grooves 421 are formed in the baffles 420. The shape of the mounting grooves 421 is adapted to the outer shape of the boosting pump 200. When the boosting pump 200 is installed in the mounting grooves 421, the baffles 420 play a supporting role for the boosting pump 200. Reinforcing plates 422 are arranged between the baffles 420 to prevent the baffles 420 from deforming.

[0024] The boosting pump 200 is a one-out-two water pump with two-way water output. One way meets the drainage needs of the piston 330, and the other way provides boosting.
