Abstract
The utility model relates to a sewer bellows for a face washing basin, which comprises a bellows main body. The upper end of the bellows main body is connected onto a water pipe of the face washing basin, the lower end of the bellows main body is sleeved in a sewer pipeline, threads are arranged on the inner side of an opening portion of the upper end of the bellows main body, and a return spring is arranged on the inner wall of the lower end of the bellows main body and connected onto a movable baffle, and the movable baffle is covered on the opening portion at the lower end of the bellows main body. The sewer bellows is simple in structure, and the inner wall of the bellows is smooth to enable water flow to pass, flow speed of the bellows is quickened, the opening portion at the upper end of the bellows is threadedly connected with a water pipe of the face washing basin, connection is firm, and sealing performance is good. When water pressure in the bellows surpasses elasticity of the return spring, the movable baffle is opened, and the water flows quickly to the sewer pipeline. When water discharging stops, the movable baffle returns, the bellows is closed, and bacteria and insects in the sewer pipeline are blocked outside the bellows by the movable baffle, thereby being clean, sanitary and convenient to use.
Description
Technical field
The utility model relates to a kind of family expenses sewer pipe, relates in particular to a kind of washing basin and uses water bellows down.
Background technology
Existing washing basin uses down that the water bellows is straight-through structure mostly, communicates with sewer pipe all the time, and bacterium in the sewer pipe and mosquito are easy to from bellows in the inlet chamber, and harmful to human is very unclean.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, from the washing basin of movable sealing, fungi-proofing worm with ripples line pipeline down.
The technical scheme of the utility model is: comprise the bellows main body; Described bellows main body upper end is connected on the washing basin water pipe; Bellows main body lower end is enclosed within the sewer pipe, and oral area inboard, said bellows main body upper end is provided with screw thread, and bellows main body lower end inwall is provided with back-moving spring; Back-moving spring is connected to sideboard, and sideboard covers the oral area in bellows main body lower end.
The diameter of described sideboard is greater than bellows main body lower end mouth diameters, less than sewer pipe oral area diameter.
The inner wall smooth of said bellows main body.
The utility model is simple in structure, and the smooth current of being convenient to of bellows main body inner wall pass through, and accelerates the velocity of liquid assets of bellows; Bellows upper end oral area adopts with the washing basin water pipe and is threaded, and is connected firmly, good airproof performance, when the hydraulic pressure in the bellows during above the elastic force of back-moving spring; Sideboard is opened, and current flow into rapidly in the sewer pipe, when stopping to discharge water; Sideboard resets; With the bellows sealing, bacterium in the sewer pipe and insect are kept off outside bellows by sideboard, clean hygiene, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is the bellows main body among the figure, the 2nd, and sewer pipe, the 3rd, back-moving spring, the 4th, sideboard.
The specific embodiment
Washing basin is used water bellows down; Comprise bellows main body 1, described bellows main body 1 upper end is connected on the washing basin water pipe, and bellows main body 1 lower end is enclosed within the sewer pipe 2; The inner wall smooth of said bellows main body 1; Oral area inboard, said bellows main body 1 upper end is provided with screw thread, and bellows main body 1 lower end inwall is provided with back-moving spring 3, and back-moving spring 3 is connected to sideboard 4; Sideboard 4 covers at bellows main body 1 lower end oral area, and the diameter of described sideboard 4 is greater than bellows main body 1 lower end mouth diameters, less than sewer pipe 2 mouth diameters.
