Description

A water-saving washing basin

technical field

The invention relates to a sanitary ware used in people's daily life, in particular to a washing basin.

Background technique

There are two major problems in my country's water resources: one is the shortage of water resources, and the other is serious water pollution. my country is a country with serious water shortage. Per capita fresh water resources are only 1/4 of the world's average level, ranking 110th in the world, and it is one of the countries with the poorest per capita water resources in the world. The per capita available water resources are only 900 cubic meters, and the distribution is extremely uneven. So saving water is the responsibility of each of us. the

Domestic water is one of the main channels for water resource utilization. In our country, there is a serious waste of water in many families. Water dripping from the faucet and repeated flushing of the toilet cause a great waste of water resources. Purchasing environmentally friendly and water-saving sanitary ware has become the key to solving the problem of waste of water resources. the

Washbasins are widely used sanitary ware in our daily life, including bathroom basins, wash basins, and kitchen sinks. There are various types of rinsing basins on the market, but most of them have a planar structure or a concave structure for the bottom surface, and water is discharged from a water tap above it for rinsing. During the use of this washbasin, if objects are directly rinsed, a large amount of water will be wasted, so it is necessary to use a basin to receive water or block the drain to receive water for rinsing. However, in real life, due to the fast pace of life and the trouble of using a basin or blocking the drain, people will directly flush the water from the tap, which will inevitably cause a great waste of water resources. the

At the same time, water taps often cause problems such as running, emitting, dripping and leaking due to quality problems or the carelessness of users; It will cause splashing of tap water and waste of tap water, which is not conducive to saving water and energy. the

Contents of the invention

The purpose of the present invention is to technically change the problems of wasting water resources in daily life such as dripping and dripping from the faucet, users directly rinsing the items to be washed against the water from the faucet, and tap water splashing caused by the rapid opening of the faucet. the

In order to solve the above problems, the present invention designs a water-saving rinsing sanitary ware and provides a water-saving water supply method. The invention can effectively save water, and at the same time, has a certain effect on improving people's bad water habits, and meets the needs of the concept of environmental protection. the

The technical scheme adopted in the present invention is as follows: a water-saving rinsing basin, comprising a basin body, a drainpipe located at the lower part of the basin body and a tap water opening and closing valve, the drainpipe is provided with a drain plug, and the basin body is The double-layer structure basin has a cavity in the middle that can accommodate running water; the inner lower part of the double-layer structure basin is arranged with a number of lower round holes around the drain plug, and the one-way flow check valve is installed on the above the lower round hole; on the upper outer edge of the outer layer of the double-layer structure basin, there are several upper round holes, and the one-way flow check valve is installed on the upper round hole; the annular water inlet pipe is wound around the The outer layer of the double-layer structure basin is fitted along the upper round hole, and a round hole corresponding to the upper round hole is left at the contact position between the annular water inlet pipe and the upper round hole, so that the The annular water inlet pipe communicates with the cavity of the double-layer structure basin body. the

In the present invention, water enters the annular water inlet pipe through the tap water inlet pipe, and the water in the annular water inlet pipe enters the cavity of the double-layer structure basin through the upper round hole, and the water in the cavity passes through the inner layer of the double-layer structure basin. The lower circular hole enters the basin body for use. After reaching required water volume, close tap water opening and closing valve and get final product. After the water in the basin is used up, the drain plug is lifted through the drain pull rod and the pull rod drainage device, and the sewage enters the drain pipe and is discharged. During the whole water use process, the set one-way flow check valve can prevent backflow pollution of sewage. In the present invention, the tap water opening and closing valve, the drainage pull rod and the pull rod drainage device all belong to the existing general technology, and are not within the protection scope of the present invention. Of course, other existing technologies can also be used, as long as the water-saving rinsing basin needs to be satisfied. The switch of water and water outlet can be used. the

The present invention has the following outstanding advantages:

1. The removal of conventional faucets makes it impossible for users to rinse items directly, resulting in waste of water;

2. The removal of conventional faucets also expands the use space of users;

3. The water slowly flows into the basin from the bottom, avoiding the waste of splashing caused by excessive water pressure after the faucet is suddenly turned on;

4. A certain amount of unavoidable running, emitting, dripping, and leaking tap water can be temporarily stored in the double-layer structure of the basin body, avoiding the waste of direct discharge.
