[0027] See Figures 1-4 , the present utility model provides a water purifier, which includes a middle shell 1 and a booster pump 2.

A limiting structure 12 is provided on the outer peripheral wall of the fixing part 11, the limiting structure 12 protrudes from the top wall of the fixing part 11, and the outer side wall of the shock-absorbing pad 3 abuts against the limiting structure 12 to limit the horizontal movement of the booster pump 2. The limiting structure 12 can position the shock-absorbing pad 3 to prevent the shock-absorbing pad 3 from being misaligned during installation, thereby affecting the fixing strength of the booster pump 2, and the connecting part between the booster pump 2 and the middle shell 1 is not likely to crack during the transportation of the machine.

[0028] Specifically, the middle shell 1 is formed by stacking two horizontally placed cylindrical barrels up and down, and the two cylindrical barrels are fixedly connected. The fixing part 11 is arranged on the top wall of the upper cylindrical barrel.

[0029] In some specific embodiments, the shock-absorbing pad 3 can be made of soft materials such as silica gel, rubber, TPU (thermoplastic polyurethane elastomer), etc., so that the shock-absorbing pad 3 has good buffering performance, thereby effectively reducing the vibration transmitted from the booster pump 2 to the middle shell 1.

[0030] Further, two of the fixing parts 11 are provided on the front side and the rear side of the top wall of the middle shell 1 respectively, one connecting part 21 is provided on the front side and the rear side of the booster pump 2 respectively, two shock pads 3 are provided on each connecting part 21, one limiting structure 12 is provided on each fixing part 11, each limiting structure 12 wraps around the two inner sides of each fixing part 11, and the four limiting structures 12 are symmetric about the left and right and the front and back respectively. Specifically, the four shock pads 3 are respectively abutted against a corresponding fixing part 11, and each shock pad 3 and each fixing part are fixedly connected by a screw, so as to fix the booster pump 2 to the middle shell 1, and has a good effect of shock absorption and noise reduction. The four limiting structures 12 respectively limit the shock pads 3 at the four corners of the booster pump 2, and limit the movement of the booster pump 2 in the horizontal direction, so as to prevent the booster pump 2 from being misaligned during the installation process.

[0031] Specifically, the limiting structure 12 wraps one-fourth of the outer side wall of the fixing part 11, and the four limiting structures 12 can be combined to form a complete circular ring structure. The four limiting structures 12 respectively limit the shock pads 3 at the four corners of the booster pump 2, so that the booster pump 2 cannot move in any horizontal direction, and can better prevent the booster pump 2 from being misaligned during the installation process.

[0032] Further, the fixing part 11 includes a fixing column 111 and a support ring 112 arranged on the outer periphery of the fixing column 111, and the limiting structure 12 is arranged on the outer peripheral wall of the support ring 112. The support ring 112 provides stable support for the shock pad 3, so that the booster pump 2 can remain stable during the working process, and avoids the increase of the vibration amplitude of the booster pump 2 due to instability.

[0033] Further, the water purifier further includes a fastener. The shock pad 3 is provided with a first mounting hole 31 arranged vertically, and the top wall of the fixing column 111 is provided with a second mounting hole 114. The fastener passes through the first mounting hole 31 and the second mounting hole 114 in sequence to fixedly connect the booster pump 2 and the middle shell 1, and the top wall of the support ring 112 abuts against the bottom wall of the shock pad 3 to support the shock pad 3. In a specific embodiment, the fastener is a screw or a bolt.

[0034] Further, the connecting part 21 is provided with a through hole, the shock pad 3 is embedded in the hole wall of the through hole, and the bottom wall of the shock pad 3 extends downward from the bottom wall of the connecting part 21. Two through holes are provided on each connecting part 21, and one shock pad 3 is embedded in the hole wall of each through hole.

[0035] Further, an annular groove is provided on the outer sidewall of the shock pad 3, and the pore wall of the through hole is clamped in the annular groove. By clamping the pore wall of the through hole into the annular groove, the shock pad 3 is fixed to the booster pump 2.

[0036] Further, a plurality of first rib strips 113 for connecting the two are provided between the support ring 112 and the fixing column 111, and the plurality of first rib strips 113 are evenly distributed in a ring shape. Specifically, the top wall of the first rib strip 113, the fixing column 111, and the top wall of the support ring 112 are on the same horizontal plane. Connecting the support ring 112 and the fixing column 111 by a plurality of first rib strips 113 is beneficial to strengthening the strength of the fixing column 111, so that when the screw is connected to the fixing column 111, good stability is achieved; on the other hand, the first rib strip 113 can increase the support surface for the shock pad 3 and provide more stable support.

[0037] Further, the limiting structure 12 includes an arc-shaped plate 121 and a plurality of second rib strips 122. The arc-shaped plate 121 is arranged on the outer periphery of the support ring 112. One end of the second rib strip 122 is connected to the outer sidewall of the support ring 112, and the other end is connected to the inner sidewall of the arc-shaped plate 121. Specifically, the second rib strip 122 is arranged on the outer peripheral wall of the support ring 112. The bottom wall of the second rib strip 122 is flush with the bottom wall of the support ring 112, and the top wall of the second rib strip 122 is higher than the top wall of the support ring 112. The height of the arc-shaped plate 121 is adapted to the height of the second rib strip 122. When the booster pump 2 is installed on the middle shell 1, the outer sidewall of each shock pad 3 abuts against the second rib strip 122 on the limiting structure 12 at the corresponding position. The arc-shaped plate 121 can enhance the stability of the structure, and the second rib strip 122 can not only position the shock pad 3 but also increase the rigidity of the support ring 112.

[0038] Further, the diameter of the support ring 112 is greater than or equal to the diameter of the shock pad 3. Ensure that the support ring 112 can provide stable support for the shock pad 3, so that the booster pump 2 can remain stable during operation and avoid the increase in the vibration amplitude of the booster pump 2 due to instability.

[0039] Further, a filter element installation hole 13 for installing a filter element is provided on the middle shell 1. The booster pump 2 is communicated with the water inlet end of the filter element, and the water inlet water pressure of the filter element is increased by the booster pump 2, thereby improving the filtration speed of the filter element.
