Description

Constant pressure water purification device

The invention relates to a water filtering device, in particular to a constant pressure water purifying device which achieves a protective effect by constant pressure.

According to the general household water, a water filtering device is additionally connected to the faucet, so that the drinking water can be obtained through the filtering water device. However, the conventional water filtering device is directly installed between the water source and the faucet switch. When the faucet switch is turned off, the water source is kept in the state of being injected into the water filtering device, so that the water pressure of the water filtering device and the water source end are the same, and the water pressure at the water source end is affected, so that the water filtering device is easily affected by the water pressure. The damage rate is a non-pressure water filtration device that has been further improved by the industry. For example, the pressure-free water purification device approved by the Department of Health and Welfare Bureau No. I317296 issued on November 21, 1998. According to the scope of the patent application and the drawings, it can be analyzed that the water source conduit combined with the valve body is connected with a water outlet seat and an on-off valve slot for accommodating the switch valve, and the water outlet switch valve slot is matched with one The inlet pipe is connected to a filter core, and the outlet pipe of the filter core is connected to the outlet of the water outlet and the water outlet of the J-type outlet section, and is formed between the water source conduit and the inlet pipe of the filter core, and is controlled by the on-off valve. By guiding the filter core to alleviate the energy force of the water hammer phenomenon in the pipeline, although the pressureless water purification device can effectively eliminate the water pressure at the filter core, it is not difficult to find out the above-mentioned conventional structure. There are some shortcomings, the main reasons are as follows: When the switch valve of the water outlet is closed, the switch valve can block the water pressure of the water source, so that the filter core is no longer affected by the water pressure of the water source, but it exists inside the filter core. Residual pressure will still promote clean water The outlet of the water outlet is discharged from the water outlet. Therefore, not only will a large amount of clean water be wasted after each use, but also the filtration amount of the filter core will be increased. On the contrary, the loss of the filter core will be accelerated, and the purpose of protecting the filter core cannot be effectively achieved. The technical problem to be solved.
