[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] As mentioned in the background technology, although traditional single-chamber or multi-chamber diaphragm booster pumps can meet the boosting requirements to a certain extent, they are often accompanied by large mechanical vibrations and noise during operation. This is because the movement of water in the pump is not smooth enough, resulting in unnecessary vibrations during the energy conversion process. In addition, due to design and material limitations, the manufacturing cost of these pumps is high, which is not conducive to large-scale promotion and application.

[0045] To improve the above problems, the present application proposes a vibration-reducing and noise-reducing five-chamber diaphragm booster pump. The pump adopts a unique five-chamber design, including five water inlet chambers and five water storage chambers. Such a multi-chamber structure can effectively disperse the impact force of the water flow and reduce the turbulence of the water flow in the pump, thereby significantly reducing vibration and noise. At the same time, the multi-chamber design also helps to improve the efficiency and stability of the pump and extend its service life.

[0046] In addition, the five-chamber diaphragm booster pump of the present invention pays special attention to cost control while maintaining high performance. The production cost is reduced by optimizing the design of the pump body structure and selecting cost-effective materials. This makes the booster pump of the present invention not only technologically advanced, but also economically competitive and able to meet the needs of a wider market.

[0047] See also Figure 1-4 As shown, a five-chamber diaphragm booster pump with vibration reduction and noise reduction according to an embodiment of the present application includes:

[0048] A housing 1, wherein a water inlet 2 and a water outlet 3 are provided on the top of the housing 1, and a pressure relief valve 4 is provided on the top of the housing 1, and the pressure relief valve 4 is fixedly connected to the top of the housing 1 by bolts;

[0049] A fixing component, the fixing component is arranged at the bottom of the shell 1, and the fixing component is fixedly connected to the bottom of the side wall of the shell 1;

[0050] A boost component is arranged in the shell 1.

[0051] In some specific embodiments, the housing comprises:

[0052] A pump housing 5, wherein a pressure relief valve 4 is disposed on the top of the pump housing 5, and the pressure relief valve 4 is fixedly connected to the top of the pump housing 5 by bolts. A water inlet 2 and a water outlet 3 are disposed on the pump housing 5, and an inner cavity 6 having a pentagonal structure with an arc-shaped profile is disposed in the pump housing 5, and an opening is disposed at the bottom of the pump housing 5;

[0056] Specifically, the outer diameter of the housing 1 of 40mm-80mm can be understood as the maximum outer diameter of the entire housing 1 of 40mm-80mm, wherein the outer diameters of the pump housing 5, the pump housing bracket 18, and the motor front cover 7 are 40mm-80mm. The volume of the entire pump is relatively small, which makes the five-chamber diaphragm booster pump more compact and convenient for use and installation in occasions with limited space. The smaller volume means a smaller range of motion for the internal mechanical parts, thereby reducing mechanical vibration and the resulting noise. In addition, the multi-chamber design helps to disperse the impact force of the water flow, further reducing the vibration and noise levels. The design of the five-chamber diaphragm booster pump makes the water flow smoother, reduces the occurrence of water hammer, and thus improves the working stability and efficiency of the pump.

This structure makes the installation of the pump more convenient and also improves the overall structural strength of the pump. The provision of the shock-absorbing pad 13 effectively absorbs the vibration generated by the pump during operation, thereby reducing noise. The shock-absorbing pad 13 can also protect the motor and prevent damage to the motor due to excessive vibration. The design of the fixing assembly of the present invention fully considers factors such as stability, ease of installation, shock absorption and noise reduction, motor protection, and cost, so that the five-chamber diaphragm booster pump not only provides efficient boosting function, but also has a good user experience and economic benefits.

The pistons 24 are provided with openings 25 for bolts to pass through. The bolts pass through the openings 25, the second openings 23, and the screw holes 21 on the pistons 24 in sequence, so that the diaphragm 19, the pump housing bracket 18 and the bearing bracket 16 are tightly connected.
