[0002] Water purification equipment is increasingly used in both domestic and industrial applications to ensure safe, clean drinking water. Booster pumps are an integral component of these water purification systems, responsible for providing sufficient pressure for the water to pass through the filtration system. However, traditional booster pump designs have several drawbacks, particularly regarding vibration and noise control.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0043] As mentioned in the background, while traditional single- or multi-chamber diaphragm booster pumps can meet boosting requirements to a certain extent, they are often accompanied by significant mechanical vibration and noise during operation. This is because the water flow within the pump is not smooth enough, resulting in unnecessary vibration during the energy conversion process. Furthermore, due to design and material limitations, these pumps are expensive to manufacture, making them unsuitable for large-scale application.

[0044] To address these issues, this application proposes a vibration- and noise-reducing six-chamber diaphragm booster pump. This pump utilizes a unique six-chamber design, comprising six water inlet chambers and six water storage chambers. This multi-chamber structure effectively disperses the impact of the water flow and reduces the turbulence within the pump, significantly reducing vibration and noise. Furthermore, the multi-chamber design helps improve the pump's efficiency and stability, extending its service life.

[0045] Furthermore, the six-chamber diaphragm booster pump of the present invention maintains high performance while also paying special attention to cost control. Through optimized pump structure design and the selection of cost-effective materials, production costs are reduced. This makes the booster pump of the present invention not only technologically advanced but also economically competitive, meeting the needs of a wider market.

[0046] See Figure 1-3 As shown, a six-chamber diaphragm booster pump with vibration and noise reduction according to an embodiment of the present application includes:

[0047] A housing 1 is provided with a water inlet 2 and a water outlet 3 on the top of the housing 1. A pressure relief valve 4 is provided on the top of the housing 1 and is fixedly connected to the top of the housing 1 by bolts;

[0048] A fixing assembly, the fixing assembly being arranged at the bottom of the housing 1 and being fixedly connected to the bottom of the side wall of the housing 1;

[0049] A boost component is provided in the housing 1 .

[0050] In some specific embodiments, the housing includes:

[0051] A pump housing 5 is provided with a pressure relief valve 4 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. The pump housing 5 is provided with a water inlet 2 and a water outlet 3. The pump housing 5 is provided with an inner cavity 6 having a hexagonal structure with an arc-shaped profile in a transverse cross section. The bottom of the pump housing 5 is provided with an opening;

[0052] A motor front cover 7 is provided with a through hole 8, and one end of the motor front cover 7 is fixedly connected to the bottom of the pump housing 5 by bolts;

[0053] A motor housing 9, the top of which is fixedly connected to the other end of the motor front cover 7, and a motor rear cover 10 is provided at the bottom of the motor housing 9;

[0054] The outer diameter of the shell 1 is 75mm-95mm, the flow rate of the water outlet 3 is 0.5L-8L / min, and the water outlet pressure of the water outlet 3 is 4-7KG.

[0055] Specifically, the outer diameter of the housing 1 of 75mm-95mm can be understood as the maximum outer diameter of the entire housing 1 is 75mm-95mm, of which the outer diameters of the pump housing 5, the pump housing bracket 18, and the motor front cover 7 are 75mm-95mm. The outer diameter of the motor base plate is larger than 75mm-95mm. The volume of the entire pump is relatively small, which makes the six-chamber diaphragm booster pump more compact and easy to use and install in occasions with limited space. The smaller volume means that the internal mechanical components have a smaller range of motion, 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 six-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.

[0058] Shock-absorbing pads 13 are provided at the four mounting holes 12 .

[0059] Specifically, the outer diameter of the motor base plate 11 is larger than the outer diameter of the motor housing 9. This design increases the stability of the entire pump and makes the pump more stable during operation. The motor base plate 11 is fixedly connected to the side wall of the motor housing 9. 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 component of the present invention fully considers multiple factors such as stability, ease of installation, shock absorption and noise reduction, motor protection, and cost, so that the six-chamber diaphragm booster pump not only provides efficient boosting function, but also has a good user experience and economic benefits.

[0068] In some specific embodiments, six second openings 23 are provided on the diaphragm 19 corresponding to the six first openings 22, and a piston 24 is provided on the top of the six second openings 23. The piston 24 is provided with an opening 25 for the passage of bolts. The bolts pass through the opening 25, the second opening 23, and the screw hole 21 on the piston 24 in sequence, so that the diaphragm 19, the pump housing bracket 18 and the bearing frame 16 are tightly connected.

[0069] In some specific embodiments, the boost assembly further comprises:
