Through holes extending in the axial direction of the pump body are formed in the positions, on the two sides of the pump body, of the fixing sleeve, the two pipelines penetrate through the two through holes in a one-to-one correspondence mode, and the pipelines are in tight fit with the corresponding through holes. When water flows through the water inlet pipe and the water outlet pipe, noise caused by shaking of the water inlet pipe and the water outlet pipe relative to the pump body can be reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and in particular to a pump used for a water purifier and the water purifier. Background Art

[0002] Currently, commercial water purifiers on the market, especially those with faster water production speeds, make very loud noises during normal water production. The industry mainly uses sound insulation cotton to wrap the PE pipes connecting the water inlet and outlet of the pump to achieve a certain noise reduction effect. The sound insulation cotton can only reduce the noise generated by the resonance of the PE pipe when the pump is working; some fix the pump in a sound insulation box, which is costly, has very limited installation scenarios, and a very complicated structure; or the fixed structure of the pump is changed to a hard buffer pad. There are limitations on the installation method of the pump when using hard materials as buffer pads. Generally, it can only be installed horizontally, not vertically.

[0003] In response to the above-mentioned noise problem, the Chinese utility model patent with application number CN201721834537.3 (publication number CN207750223U) discloses a two-stage vibration reduction device for a diaphragm booster pump base, which is arranged on a base, and the base is installed on the body of the diaphragm booster pump, including an arc-shaped iron sheet of the base, which is fixed to the pump body of the diaphragm booster pump by a first screw, and several first-level vibration-isolating rubber pads are installed between the arc-shaped iron sheet of the base and the iron plate of the base by a second screw, and several second-level vibration-isolating rubber pads are installed on the iron sheet of the base, and the base is installed on the water purifier with screws through the second-level vibration-isolating rubber pads.

[0004] The vibration reduction device of this patent is mainly used to position and reduce vibration of the pump casing, but the water inlet pipe and the water outlet pipe connected to the pump are also prone to vibration when water flows through, so the vibration reduction device needs to be further improved.

The mounting plate and the positioning plate are connected by a connecting component, which can reduce the vibration of the pump body itself when it is working.

[0010] The connection assembly can have a variety of structural forms, such as snap-on connection, etc. Preferably, the connection assembly includes a bolt and a nut, the bolt passes through the mounting plate and the positioning plate in sequence, the head of the bolt abuts against the wall of the mounting plate facing away from the positioning plate, the nut is connected to the bolt, and the nut abuts against the wall of the positioning plate facing away from the mounting plate. The matching mode of the bolt and the nut is simple in structure and easy to purchase.

[0011] In order to further reduce the vibration between the bolt and the positioning plate, a positioning hole penetrating the wall thickness of the positioning plate is opened, a vibration-damping pad is embedded in the positioning hole, and the bolt passes through the vibration-damping pad.

[0012] In order to install the vibration-damping pad in the positioning hole, a circle of embedding grooves is provided on the peripheral wall of the vibration-damping pad along its circumference, and the portion of the positioning plate located at the peripheral edge of the positioning hole is embedded in the embedding grooves.

[0013] Preferably, a plurality of convex portions are distributed on the wall surface of the positioning plate facing the pump body, and the convex portions can effectively reduce the reflection of noise.

The connecting components are arranged on both radial sides of the pump body, and at least two groups of the connecting components are arranged at intervals in the vertical direction.

[0016] The technical solution adopted by the utility model to solve the above second technical problem is: a water purifier, characterized in that it includes a water purifier using the above pump.

[0017] Compared with the prior art, the utility model has the following advantages: the utility model has a fixed sleeve fixed on the pump body, and the two pipes, the water inlet pipe and the water outlet pipe, are fixed on the fixed sleeve, so that when water flows through the water inlet pipe and the water outlet pipe, the noise caused by the shaking of the water inlet pipe and the water outlet pipe relative to the pump body can be reduced.
