[0005] Preferably, the accommodating chamber is formed by an arc-shaped wall and two flat walls. One end of each of the two flat walls is connected to both ends of the arc-shaped wall.

The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention. In addition, the term "or" used herein should, as appropriate, include any combination of any one or more of the associated listed items.

[0016] [Example]

[0017] Please refer to Figures 1 to 4. The present invention provides a shock-absorbing low-noise booster pump that can be applied to devices such as water heaters. The shock-absorbing low-noise booster pump includes a booster pump body 1 and a silencer 2.

[0018] The booster pump body 1 includes a motor 11. The motor 11 has an inlet 12 and an outlet 13 on one side. The motor 11 is connected to an impeller 14 (as shown in Figure 4), which is positioned between the inlet 12 and the outlet 13. The motor 11 drives the impeller 14 to rotate, thereby pumping fluid through the inlet 12 to the outlet 13 to increase water pressure and enable rapid fluid transport. Since the booster pump body 1 is prior art, and this invention does not limit the structure of the booster pump body 1, it will not be described in detail.

[0019] The silencing device 2 is located near the outlet 13 of the booster pump body 1. A receiving chamber 15 is provided near the outlet 13 of the booster pump body 1. The receiving chamber 15 is a recessed space, and one end of the receiving chamber 15 may be open to facilitate the assembly of the silencing device 2. The receiving chamber 15 is connected to the inlet 12 via an inlet end 151 (as shown in Figures 4 and 5), and to the outlet 13 via an outlet end 152, allowing fluid to be sequentially transported forward through the inlet 12, the receiving chamber 15, and the outlet 13.

[0020] The cross-sectional shape of the receiving chamber 15 is not limited, but preferably, the receiving chamber 15 has its maximum width near the inlet end 151 (as shown in Figure 5). The cross-section of the receiving chamber 15 can be teardrop-shaped, that is, the receiving chamber 15 can be formed by an arcuate wall 153 and two flat walls 154. One end of the two flat walls 154 is connected to the two ends of the arcuate wall 153, and the distance between the two flat walls 154 decreases in the direction away from the arcuate wall 153. The other ends of the two flat walls 154 are connected. The inlet end 151 can be located in the middle of the arcuate wall 153, and the outlet end 152 can be located at the connection of the two flat walls 154, so that the width of the receiving chamber 15 decreases from the direction of the inlet end 151 to the direction of the outlet end 152, which can provide a better flow guiding effect and improve the vibration reduction and noise reduction performance.

[0021] The silencing device 2 includes a shock-absorbing cylinder 21 and a shock-absorbing pad 22. The shock-absorbing cylinder 21 is disposed within the accommodating chamber 15. The shock-absorbing cylinder 21 is a hollow cylinder (as shown in Figures 5 to 7). The shock-absorbing cylinder 21 has an inner surface 211 and an outer surface 212. The shock-absorbing cylinder 21 has multiple perforations 213 that penetrate the inner surface 211 and the outer surface 212, thus forming a porous structure. When the shock-absorbing cylinder 21 is disposed within the accommodating chamber 15, an appropriate gap can be reserved between the outer surface 212 of the shock-absorbing cylinder 21 and the main body 1 of the pressure pump to allow fluid to pass through.

[0022] The shape of the damping cylinder 21 is not limited. Preferably, the shape of the damping cylinder 21 can correspond to the housing 15, that is, the shape of the damping cylinder 21 can also be teardrop-shaped. The damping cylinder 21 can include an arc plate 214 and two flat plates 215. The perforations 213 are distributed on the arc plate 214 and the two flat plates 215. One end of the two flat plates 215 is connected to the two ends of the arc plate 214 respectively. The distance between the two flat plates 215 decreases in the direction away from the arc plate 214. The other ends of the two flat plates 215 are connected, so that the width of the damping cylinder 21 decreases from the direction of the inlet end 151 to the direction of the outlet end 152, which can provide a better flow guiding effect and improve the damping and noise reduction performance. Preferably, the connection of the other ends of the two flat plates 215 can be arc-shaped, so that the fluid can flow out more smoothly.

[0023] In this embodiment, one end of the shock absorber 21 is connected to a cover 23, which can seal one end of the accommodating chamber 15. The cover 23 can be fixed to the pressure pump body 1 by means of screws 24, etc., to facilitate the assembly of the silencer 2 onto the pressure pump body 1. A sealing element 25 can also be provided on the inner side of the cover 23 (as shown in Figure 4) to improve the sealing effect.

[0024] As the fluid flows from the inlet 12 to the outlet 13, it comes into contact with the perforations 213. The porous structure of the damping cylinder 21 can be used to reduce vibration and noise. The vibration and noise of the fluid can be dissipated by friction in the porous structure. The damping cylinder 21 reduces vibration and noise, especially for high-frequency noise reduction.

[0025] The damping pad 22 is made of an elastic material, such as silicone, and provides cushioning, shock absorption, and noise reduction. The damping pad 22 is disposed inside the damping cylinder 21. When fluid enters the damping cylinder 21 through the perforations 213, the fluid impacts the damping pad 22, thus providing shock absorption and noise reduction, further enhancing the effect of reducing vibration and noise.

[0026] In this embodiment, the damping pad 22 can be a hollow cylinder. Preferably, the cross-sectional thickness of the damping pad 22 is greater than that of the damping cylinder 21, thus providing a better elastic buffering effect. The shape of the damping pad 22 is not limited. Preferably, the shape of the damping pad 22 can correspond to that of the damping cylinder 21, that is, the shape of the damping pad 22 can also be teardrop-shaped. The damping pad 22 can include an arc-shaped plate 221 and two flat plates 222. One end of the two flat plates 222 is connected to the two ends of the arc-shaped plate 221, and the distance between the two flat plates 222 decreases in the direction away from the arc-shaped plate 221. The other ends of the two flat plates 222 are connected, so that the width of the damping pad 22 decreases from the direction of the inlet end 151 to the direction of the outlet end 152, thereby providing a better flow guiding effect and improving the damping and noise reduction performance. The shock-absorbing pad 22 can be used to absorb vibration and noise, so that the vibration and noise of the fluid can be absorbed by the shock-absorbing pad 22, and the transmission to the outside can be reduced, which can further improve the shock absorption and noise reduction performance.

[0027] [Beneficial Effects of the Examples]

The shock-absorbing cylinder is disposed within the receiving chamber of the booster pump body and is a hollow cylinder with an inner surface and an outer surface. Multiple perforations are provided on the shock-absorbing cylinder, penetrating both the inner and outer surfaces, creating a porous structure. The shock-absorbing pad is made of elastic material and is disposed within the shock-absorbing cylinder. This invention's silencing device employs fluid dynamics optimization. Through the internal fluid channel design of the porous structure of the shock-absorbing cylinder, turbulence and noise during fluid flow can be reduced. The shock-absorbing pad, made of elastic material, further reduces vibration transmission, thereby improving vibration damping and noise reduction efficiency.

[0029] Preferably, the containment chamber is formed by an arc-shaped wall and two flat walls. One end of each flat wall is connected to one end of the arc-shaped wall, and the distance between the two flat walls decreases towards the direction away from the arc-shaped wall. The other ends of the two flat walls are connected. The inlet is located in the middle of the arc-shaped wall, and the outlet is located at the junction of the two flat walls. Thus, the width of the containment chamber decreases from the inlet to the outlet, providing a better airflow guiding effect and improving vibration and noise reduction performance.
