Description

[0002] The water purifier is a household or commercial equipment for purifying water quality. In order to realize cold and hot water diversion supply, most water purifiers are equipped with core components such as cold water pump and hot water pump.

[0003] During the operation of the water purifier, the cold water pump and the hot water pump will produce vibration. These vibrations not only cause noise problems, but also affect the stability and service life of the water purifier. In the design of the water purifier, the cold water pump and the hot water pump are usually directly and rigidly fixed on the main support, lacking effective vibration reduction measures, resulting in vibration transmission to the main support and the shell, causing resonance problems, further increasing the noise during the operation of the water purifier, and thus affecting the user experience and the performance of the equipment. In order to improve the above problems, some water purifiers use multi-point fixation to disperse vibration, install the water pump on the main support through multiple fixing points to disperse vibration energy and reduce vibration transmission of a single fixing point. However, multi-point fixation needs accurate design, otherwise it may cause vibration to intensify at certain frequencies, and also causes complex water pump installation, increasing the difficulty of production and maintenance.

[0004] Therefore, there is an urgent need for a water purifier that can effectively isolate water pump vibration, reduce noise, facilitate installation and improve equipment stability. CONTENT OF THE INVENTION
