Abstract

A kind of noise reduction overflow pipe, comprise supervisor and intake pipe, have noise reduction tank at described supervisor's internal upper part, described intake pipe has hush pipe, described hush pipe is in described noise reduction tank.

Description

Noise reduction overflow pipe

Technical field

The utility model relates to bathroom field, particularly relates to the noise reduction overflow pipe on the drain valve in cistern.

Background technique

Existing toilet has one water route to guide overflow pipe drain valve into for toilet moisturizing from inlet valve when water tank water intake, because the higher water causing flowing out of hydraulic pressure is comparatively large thus send larger sound to the impact of air.

Model utility content

The purpose of this utility model is to provide a kind of noise reduction overflow pipe, and it can abate the noise.

To achieve these goals, the noise reduction overflow pipe that the utility model provides, is characterized in that: comprise supervisor and intake pipe, have noise reduction tank at described supervisor's internal upper part, described intake pipe has hush pipe, described hush pipe is in described noise reduction tank;

As the improvement of the utility model noise reduction overflow pipe, its further feature is: the bottom surface of described noise reduction tank is inclined-plane, and the lower end on described inclined-plane is affixed to overflow pipe inwall;

As the improvement of the utility model noise reduction overflow pipe, its further feature is: the suitable for reading of described noise reduction tank is inclined-plane, and the lower end on described inclined-plane is affixed to overflow pipe inwall.

The beneficial effects of the utility model are:

Structure is simply easily manufactured, reduces noise during water tank water intake.

Fig. 3 is the sectional view of the supervisor of noise reduction overflow pipe of the present utility model.

Fig. 4 is the schematic diagram of the intake pipe of noise reduction overflow pipe of the present utility model.

Fig. 5 is the schematic diagram of noise reduction overflow pipe of the present utility model.

Fig. 6 is the sectional view of noise reduction overflow pipe of the present utility model.

Embodiment

Consult Fig. 1, Fig. 2, Fig. 3, supervisor 1 has noise reduction tank 2, intake pipe locating button 3, noise reduction tank 2 has suitable for reading 4, bottom surface 5, wherein suitable for reading 4 of noise reduction tank 2 be inclined-plane with bottom surface 5, suitable for reading 4 of noise reduction tank 2 and the lower end on the inclined-plane of bottom surface 5 be affixed to supervisor 1 inwall;

Consult Fig. 4, intake pipe 6 has hush pipe 7, wherein intake pipe 6 boring;

Consult Fig. 1 to Fig. 6, intake pipe 6 is arranged on the intake pipe locating button 3 on supervisor 1.

When the flow direction intake pipe 6 of guiding into from inlet valve, current flow to noise reduction tank 2 from hush pipe 7, make to be full of water in noise reduction tank 2, then just overflow from suitable for reading 4 of noise reduction tank 2, because suitable for reading 4 and bottom surface 5 of noise reduction tank 2 are inclined-plane, thus current can be dirty along supervisor 1 inwall from the lower end on inclined-plane.

Model utility point of the present utility model to be mainly to make from hush pipe 7 high speed water out with air direct collision, sound to be produced, but to make from hush pipe 7 high speed water out rush at water in noise reduction tank 2, thus achieves noise reduction.

Claims

1. the noise reduction overflow pipe on the drain valve in cistern, is characterized in that: comprise supervisor and intake pipe, have noise reduction tank at described supervisor's internal upper part, described intake pipe has hush pipe, described hush pipe is in described noise reduction tank; The bottom surface of described noise reduction tank is inclined-plane, and the lower end on described inclined-plane is affixed to described noise reduction overflow pipe inwall; The suitable for reading of described noise reduction tank is inclined-plane, and the lower end on described inclined-plane is affixed to described noise reduction overflow pipe inwall.
