Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a water purifier with easy filter replacement. Background Technology

[0002] A water purifier is generally a small water purifier used in the home. Water purifiers mainly rely on filter cartridges to purify water. In order to ensure the water purification effect, the filter cartridges generally need to be replaced regularly.

[0003] Replacing the filter cartridge in most existing water purifiers involves disassembling the filter cartridge and the main body with a screwdriver, and then removing the filter cartridge. This process is quite cumbersome. In addition, the water outlet of most existing water purifiers is exposed, making it susceptible to damage from bumps and knocks. Furthermore, accidental contact with the water outlet can also contaminate the water. These issues need to be addressed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a water purifier with easy filter replacement, which solves the technical problem of low filter replacement efficiency in existing water purifiers.

[0006] The filter element mechanism includes a filter element shell fixedly connected to one side of the top of the base, a filter bottle fixedly connected inside the filter element shell, a filter element body inside the filter bottle, a limit cover fixedly connected to the inner top of the filter element shell, a filter cover slidably installed inside the limit cover, and a button provided in the center of the filter cover.

[0007] The filter element mechanism also includes a plastic clip at the bottom of the button, the bottom of the plastic clip is provided with a top plate, and a return spring is fixedly connected to the bottom of the button, with the bottom end of the return spring fixedly connected to the center of the top wall of the top plate.

[0008] A reset ring is fixedly installed at the bottom of the limiting cover. Two fixing rings are provided on the inner wall of the reset ring. Four limiting posts are slidably installed inside the reset ring. Each limiting post is fitted with a compression spring, which is located on both sides of the bottom fixing ring.

[0009] Preferably, the plastic locking ring has six locking claws equidistantly arranged in its circumference, and the inner wall of the limiting cover has limiting holes corresponding to the locking claws.

[0010] Preferably, the base is provided with a water inlet pipe near the bottom of the outer shell, the water inlet pipe is in through communication with the filter bottle, and two connecting pipes are symmetrically provided on the top of the filter bottle, the ends of the two connecting pipes are in through communication with the pulse bottle.

[0011] Preferably, the pulse bottle is equipped with a booster pump at the top, and the water delivery end of the booster pump is symmetrically provided with two hoses, the other ends of the two hoses being respectively located on both sides of the outer shell.

[0012] Preferably, an annular handle is rotatably provided on the outer side of the outer shell, the annular handle is rotatably sleeved on the outer side of the hose, the annular handle has a hollow tube inside and is connected to both ends of the hose, and the bottom inner side of the annular handle has a water outlet.

[0013] Preferably, a touch screen is provided on the top of the outer casing;

A limit cover 33 is fixedly connected to the inner top of the filter element shell 30. A filter cover 34 is slidably installed inside the limit cover 33, and a button 35 is located at the center of the filter cover 34. The filter element mechanism 3 also includes a plastic retaining block 36 located at the bottom of the button 35. A top plate 37 is located at the bottom of the plastic retaining block 36. A return spring 38 is fixedly connected to the bottom of the button 35, and the bottom end of the return spring 38 is fixedly connected to the center of the top wall of the top plate 37. The bottom of the limit cover 33 is fixedly... A reset ring 39 is fixedly installed. The inner wall of the reset ring 39 is provided with two fixing rings. Four limiting posts 310 are slidably installed inside the reset ring 39. Each limiting post 310 is fitted with a compression spring 311. The compression spring 311 is located on both sides of the bottom fixing ring. When replacing the water purifier, first open the filter cartridge shell 30, press the button 35, the reset spring 38 is compressed, the top plate 37 moves down, causing the limiting posts 310 to move down. At this time, the compression spring 311 is compressed, the plastic locking block 36 at the bottom retracts, and under the pushing action of the compression spring 311, the filter cover 34 is lifted up. Then, the filter cover 34 together with the filter cartridge body 32 below is taken out to replace the internal filter cartridge.

[0032] The plastic locking block 36 has six locking claws equidistantly arranged around its circumference. The inner wall of the limiting cover 33 has limiting holes 312 corresponding to the locking claws. After replacement, during installation, the locking claws of the plastic locking block 36 are aligned with the limiting holes 312 on the inner side of the limiting cover 33, and the filter element body 32 is installed. Since the bottom of the locking claws of the plastic locking block 36 is a wedge-shaped surface, its top and the limiting hole 312 are engaged and limited to each other, and the filter element body 32 is installed.

An annular handle 22 is rotatably provided on the outer side of the outer shell 2. The annular handle 22 is rotatably sleeved on the outer side of the hose. The annular handle 22 has a hollow tube inside and is connected to both ends of the hose. A water outlet 24 is provided on the inner side of the bottom of the annular handle 22. The purified water enters the hollow tube inside the annular handle 22 through the hose at the top of the pulse bottle 23 and finally flows out along the water outlet 24.

[0037] As a preferred technical solution in this embodiment, a touch screen 21 is provided on the top of the outer casing 2, and the touch screen 21 is used to control the water purifier switch;

[0038] As a preferred technical solution in this embodiment, a touch switch for controlling the start of the booster pump 4 is provided at the rotatable connection between the annular handle 22 and the outer casing 2. When taking water, rotate the annular handle 22 to make it rotate to a horizontal state. At this time, the touch switch is turned on to control the booster pump 4 to start, so that the purified water is drawn out by the booster pump 4, passes through the hose inside the annular handle 22, and finally flows out along the outlet 24 at the bottom. After taking water, rotate the annular handle 22 to return it to the initial state. At this time, the touch switch controls the booster pump 4 to turn off, and the water taking is suspended.
