Description

Technical Field

[0001] The utility model relates to the technical field of booster pumps, in particular to a booster pump. Background Art

[0002] With the improvement of modern people's quality of life and the emphasis on health, people's requirements for the purity and cleanliness of drinking water are increasing. As a device that purifies and filters water through physical adsorption and filtration, water purifiers are gradually entering more and more households.

[0003] Among them, the booster pump is an important component of the water purifier. The noise of the booster pump mainly comes from the vibration noise of the single pump. In addition, when the water purifier is in normal working condition, the pump head water pipe and the bottom bracket have the negative effect of transmitting resonance and amplifying the vibration noise of the pump head. During the operation of the water purifier, since the booster pump needs to reciprocate and pressurize water through the piston and diaphragm, the piston will inevitably produce unbalanced rotation during the reciprocating motion. In addition, people currently hope that the size of the booster pump motor is as small as possible, which will cause the center of gravity of the booster pump to move forward. The existing booster pump fixing bracket cannot well support the booster pump with the center of gravity moved forward, causing the booster pump to easily produce obvious vibrations, and the vibrations are transmitted to the water purifier through the bracket, resulting in large vibrations and noise, which has a negative impact on users.

[0031] See also Figure 1-Figure 7 The present invention provides a booster pump comprising a pump body 1, a pump head 2, a fixing bracket 3, and at least one cushioning pad 4. The cushioning pad 4 is disposed on the fixing bracket 3 and is used to form a flexible connection with a water purifier. The pump body 1 is connected to the pump head 2, and the fixing bracket 3 is detachably connected to the pump body 1 and disposed near the pump head 2. By arranging the fixing bracket 3 near the pump head 2, the fixing point of the booster pump is close to the pump head 2, thereby preventing large vibrations and noises generated by the operation of the pump head 2 and achieving a shock-absorbing effect for the water purifier.

[0032] It should be noted that the fixing bracket 3 is installed at the position of the centroid of the booster pump, so that the booster pump is at the balance point of the fixing bracket 3, with uniform force, balanced operation and lower noise.

[0033] Furthermore, the fixing bracket 3 includes an arcuate connecting portion 31, a first supporting portion 32, and a second supporting portion 33. The two ends of the arcuate connecting portion 31 are respectively connected to the first supporting portion 32 and the second supporting portion 33. The arcuate connecting portion 31 is connected to the pump body 1. The first supporting portion 32 and the second supporting portion 33 are each provided with at least one buffer pad 4. The arcuate connecting portion 31 cooperates with the outer circumference of the pump body 1. The first supporting portion 32 and the second supporting portion 33 are used to mount the booster pump to the housing of the water purifier.

[0034] Furthermore, the booster pump includes at least one fastener 5. The pump body 1 is provided with at least one first mounting hole 11, and the arcuate connecting portion 31 is provided with at least one second mounting hole 311. The fastener 5 sequentially passes through the second mounting hole 311 and the first mounting hole 11 to securely connect the fixing bracket 3 to the pump body 1. When the number of the first mounting hole 11 and the number of the second mounting hole 311 are both one, the second mounting hole 311 is provided at the center of the arcuate connecting portion 31, so that the fixing bracket 3 can be stably fixed to the pump body 1.

[0035] Furthermore, the booster pump includes at least two fasteners 5, the number of first mounting holes 11 is at least two, the two first mounting holes 11 are arranged diagonally, the number of second mounting holes 311 is four, and the four second mounting holes 311 are respectively arranged at the four corners of the arc-shaped connecting portion 31, and each two diagonally opposite second mounting holes 311 can correspond to two first mounting holes 11. When there are two first mounting holes 11 and four second mounting holes 311, the two first mounting holes 11 are arranged diagonally, and the fixing bracket 3 can be installed either upright or reversed after being rotated 180°, which improves installation convenience and facilitates assembly efficiency.

[0036] In a specific embodiment, the fasteners 5 are screws, and there are three of them. The number of the first mounting holes 11 is also three, and the three first mounting holes 11 are distributed on the pump body 1 in a right-angled triangle shape. The number of the second mounting holes 311 is four, and the four second mounting holes 311 are respectively arranged at the four corners of the arc-shaped connecting portion 31, wherein the three second mounting holes 311 correspond one-to-one with the three first mounting holes 11, and the fixing bracket 3 is fixed to the pump body 1 by screws; and when the fixing bracket 3 is rotated 180°, there are also three second mounting holes 311 that match the three first mounting holes 11, and the fixing bracket 3 can also be fixed to the pump body 1. When installing the fixing bracket 3, there is no need to fix the direction, and the fixing bracket 3 can be installed either upright or inverted, which improves the convenience of installation, helps to improve assembly efficiency, and makes the fixing bracket 3 more stable.

[0037] Furthermore, third mounting holes 34 are provided at the edges of the first support portion 32 and the second support portion 33. An annular slot 41 is provided on the side of the buffer pad 4, which is engaged with the wall of the third mounting hole 34. Specifically, the buffer pad 4 can be made of a soft material such as silicone, rubber, TPU (thermoplastic polyurethane elastomer), or a spring. It can form a barrier between the booster pump and the water purifier housing, reducing the amount of vibration transmitted from the booster pump to the water purifier housing, thereby reducing the vibration noise of the water purifier. The buffer pad 4 has a hollow structure, which facilitates its deformation for installation in the third mounting hole 34.

[0038] Furthermore, the central axis of the third mounting hole 34 is arranged radially toward the pump body 1. Since the side wall of the pump body 1 is usually mounted on the housing of the water purifier, the central axis of the third mounting hole 34 is arranged radially toward the pump body 1. This allows the buffering foot pad 4 to face the housing of the water purifier after being mounted in the third mounting hole 34, thereby forming a soft contact with the housing of the water purifier.

[0039] Furthermore, the diameter of the pump body 1 is smaller than the diameter of the pump head 2 , and the buffer foot pad 4 is radially protruded from the pump head 2 to prevent the pump head 2 from colliding with the housing of the water purifier.

[0040] Furthermore, first reinforcing ribs 35 are provided at the connections between the arcuate connecting portion 31 and the first supporting portion 32 and the second supporting portion 33. The provision of the first reinforcing ribs 35 further increases the rigidity and strength of the fixing bracket 3, reduces the possibility of the angle between the arcuate connecting portion 31 and the first supporting portion 32 and the second supporting portion 33 changing under the action of external forces, and improves the support stability of the fixing bracket 3.

[0041] Furthermore, the first reinforcing rib 35 is formed by an outwardly recessed inner wall at the connection between the arc-shaped connecting portion 31 and the first supporting portion 32 and the second supporting portion 33. Optionally, the first reinforcing rib 35 can also be an independent structure and fixedly connected to the arc plate structure. The connection method of the first reinforcing rib 35 can be welding, bonding, screw connection, etc., which is not further limited here.

[0042] Specifically, the arc-shaped connecting portion 31 and the first support portion 32 and the second support portion 33 are all rounded transitions, and the connection between the two is an arc plate structure, and the first reinforcing rib 35 is arranged on the outside of the arc plate structure. The number of the first reinforcing ribs 35 can also be two, four or more, which can be selected according to actual needs. The connection between the arc-shaped connecting portion 31 and the first support portion 32, and the connection between the arc-shaped connecting portion 31 and the second support portion 33 can have the same number of first reinforcing ribs 35, or can have different numbers of first reinforcing ribs 35. When there are multiple first reinforcing ribs 35 on one side of the arc-shaped connecting portion 31, the multiple first reinforcing ribs 35 can be arranged along the axial direction of the arc plate structure. Optionally, a broken line transition or other structure can be adopted between the arc-shaped connecting portion 31 and the first support portion 32 and the second support portion 33, and the shape of the first reinforcing rib 35 can be adaptively designed.

[0043] Specifically, the first reinforcing rib 35 is formed by an outwardly recessed inner side surface of the arc plate structure, and the first reinforcing rib 35 is integrally formed with the arc plate structure. Alternatively, the first reinforcing rib 35 may be a separate structure fixedly connected to the arc plate structure. The first reinforcing rib 35 may be connected by welding, bonding, screw connection, etc., and the specific connection is not further limited here.

[0044] Optionally, when the supporting strength is satisfied, the first reinforcing rib 35 may not be provided at the connection between the arc-shaped connecting portion 31 and the first supporting portion 32 and the second supporting portion 33 .

[0045] Furthermore, the arc-shaped connecting portion 31, the first supporting portion 32 and the second supporting portion 33 are an integrally formed structure. Specifically, the fixing bracket 3 is formed by processing sheet metal material to form the arc-shaped connecting portion 31, the first supporting portion 32 and the second supporting portion 33.

[0046] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
