Water switching device and water purifier host thereof

Abstract

The invention discloses a water switching device which comprises a water sealing mechanism movably connected with a bimodal-pore silica gel pad and a switch key mechanism connected with the water sealing mechanism and used for driving the water sealing mechanism to move, wherein a raw water through hole and a pure water through hole are formed in the bimodal-pore silica gel pad; the water sealing mechanism forms certain angle with the bimodal-pore silica gel pad; the bimodal-pore silica gel pad is fixed; and under the drive of the switch key mechanism, the water sealing mechanism is in sealed connection with the raw water through hole or pure water through hole to switch between pure water and raw water. The invention also discloses a water purifier host comprising the water switching device. Compared with the prior art, the device disclosed by the invention has the advantages of elaborate structure design, compact structure, small volume and strong airtightness; the key switch component and the water sealing component cooperate to control the water flow direction through a key way, and the switch between raw water and pure water is more free and quicker; and the host with a few parts and a good water sealing effect is convenient to assemble / disassemble and replace, the cost is lowered, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water switching device and a water purifier host. Background technique [0002] With the improvement of people's awareness of water purification, a wide variety of faucet-type water purifiers have appeared on the market. At present, there are many different principles and methods for switching between raw water and purified water in faucet-type water purifiers. The water method is often rotary water control, etc., but generally the control switching water device is installed inside the main unit of the water purifier, but the main unit is generally small in size, and the various parts of the water control components are added to the main unit, which will inevitably lead to water purification. The structure of the host machine is more complicated, not only has many parts, but also is prone to water leakage and inconvenient maintenance, which easily brings un...
