Description

Technical Field

[0001] The present invention relates to the technical field of diaphragm pumps, and in particular to a pump head structure of a six-chamber diaphragm booster pump. Background Art

[0002] As people's living standards improve, the requirements for drinking water quality are getting higher and higher. As a device that can effectively remove impurities, bacteria and other harmful substances in water, water purifiers are increasingly favored by consumers. However, in the use of water purifiers, the pump head, as one of its core components, often affects the user experience due to the noise generated during operation. In the traditional water purifier pump head structure design, although some noise reduction measures have been taken, there are still many shortcomings. In the prior art, the pump head usually adopts a simple physical isolation method to reduce noise propagation, such as filling the inside or outside of the pump shell with sound insulation cotton. Although this method reduces the noise level to a certain extent, due to the lack of a specially designed sound insulation cavity structure, the overall sound insulation performance is not ideal. Especially after long-term operation, the sound insulation material may age and fail, further weakening the noise reduction effect. In order to ensure good sound insulation performance, in addition to effective sound insulation materials, it is also necessary to ensure that the entire system is well sealed to prevent sound leakage caused by air flow. However, in actual applications, due to manufacturing process limitations or wear and tear caused by long-term use, air leakage is very likely to occur, which not only reduces the sound insulation efficiency, but also may affect the normal working state of the pump head. In order to achieve better sound insulation, some existing water purifier pump heads will add additional sound insulation components or structures in the design, which makes the entire device more complicated, not only increasing the production cost, but also bringing inconvenience to the subsequent installation and maintenance. For ordinary users, overly complicated operation procedures may reduce their enthusiasm for replacing filter elements or other maintenance work. At the same time, the pump head is prone to water leakage and poor sealing. Summary of the invention

[0009] In some embodiments, the sound insulation cavity is arranged on the bottom wall of the pump casing, and the sound insulation cavity extends along the bottom wall of the pump casing into the pump casing to the top of the pump casing.

[0010] In some embodiments, a support plate is provided in the sound insulation cavity, and the support plate includes:

[0011] A first sound insulation board, wherein the first sound insulation board is arranged in the middle of the sound insulation cavity, and the distance between the first sound insulation board and the top wall of the sound insulation cavity is the same as the distance between the first sound insulation board and the bottom wall of the sound insulation cavity;

The design of adding a sealing gasket at the bottom of the pump casing helps to improve the sealing of the entire system. A good seal can not only prevent liquid leakage, but also avoid sound leakage caused by air flow, further enhancing the sound insulation effect. This is crucial to ensure the long-term and stable operation of the water purifier. The six water-containing chamber structures designed in the pump casing enable the limited space to be more reasonably allocated and used. Each chamber can be adjusted in size or shape according to actual needs to meet the needs of different types of filter elements, thereby improving the flexibility and adaptability of the overall device. Compared with the traditional complex sound insulation scheme, the design in this application is more concise and easy to implement.

In addition, the reasonable structural layout is also conducive to reducing mechanical wear, thereby extending the service life of the pump head and even the entire water purification system. While reducing noise pollution by improving the sound insulation effect, it also means reducing the impact on the surrounding environment. In addition, since the improved product is more durable and reliable, it reduces the need for frequent replacement of parts, which is conducive to saving resources and protecting the environment in the long run.

[0035] As mentioned in the background technology, although some noise reduction measures have been taken in the design of the traditional water purifier pump head structure, there are still many shortcomings.

At the same time, the pump head is prone to water leakage and has poor sealing.

[0036] In order to improve the above problems, a six-chamber diaphragm booster pump head structure proposed in this application can greatly reduce the noise generated by the pump head during operation by setting a special sound insulation chamber at the bottom of the pump housing and filling it with efficient sound insulation cotton material. This design can not only effectively absorb and block the propagation path of noise, but also reduce the additional noise caused by vibration, thereby providing users with a quieter use experience. The design of adding a sealing gasket at the bottom of the pump housing helps to improve the sealing of the entire system. A good seal can not only prevent liquid leakage, but also avoid sound leakage caused by air flow, further enhancing the sound insulation effect. This is crucial to ensure the long-term and stable operation of the water purifier. The six water-containing chamber structures designed in the pump housing enable the limited space to be more reasonably allocated and used.

The pump casing 1 is provided with an inner cavity, and the bottom of the pump casing 1 is provided with an opening, the pump casing 1, the pump casing bracket 2, and the motor front cover 3 are fixedly connected by bolts, and the bottom of the motor front cover 3 is fixedly connected to the top of the motor casing 4, characterized in that a sound insulation cavity 5 is provided around the bottom of the pump casing 1, sound insulation cotton is provided in the sound insulation cavity 5, a sealing gasket 6 is provided at the bottom of the pump casing 1, and 6 water containing cavities 7 are provided in the pump casing 1, the diameter of the six-chamber diaphragm booster pump head structure is 75mm-95mm, the outlet flow rate of the six-chamber diaphragm booster pump head structure is 0.5L-8L / min, and the outlet water pressure is 4-7KG;

[0038] The pump housing bracket 2 is provided with 6 circular through holes 14, the top surface of the pump housing bracket 2 is provided with a diaphragm 15, the bottom of the pump housing bracket 2 is provided with a bearing frame 16, the bearing frame 16 is provided with 6 mounting seats 17 corresponding to the 6 circular through holes 14, the mounting seats 17 are provided with threaded holes, the diaphragm 15 is provided with six first through holes 18 corresponding to the 6 circular through holes 14, the diaphragm 15 matches the shape of the groove fitting surface at the top of the pump housing bracket 2, and can be tightly fitted;

[0039] Six pistons 19 are provided at the top of the diaphragm 15 corresponding to the six first through holes 18. Bolts pass through the through holes in the pistons 19, the first through holes 18 on the diaphragm 15, the circular through holes 14, and the threaded holes on the mounting seat 17 in sequence to fix the pistons 19, the diaphragm 15, the pump housing bracket 2, and the bearing bracket 16. The mounting seat 17 is used to support the diaphragm 15.

[0040] An intermediate plate 20 is arranged in the groove at the top of the diaphragm 15, and the outer diameter of the intermediate plate 20 matches the inner diameter of the top of the diaphragm 15. The intermediate plate 20 is tightly fitted with the diaphragm 15. The intermediate plate 20 is provided with 6 water inlet chambers 21 corresponding to the 6 first through holes 18. The 6 water inlet chambers 21 are not connected to each other. The water inlet chambers 21 are covered on the piston 19. Suction valves 22 are arranged in the six water inlet chambers 21. A discharge valve 23 is arranged at the center of the intermediate plate 20. An O-ring is arranged between the discharge valve 23 and the intermediate plate 20. A stepped groove 24 is arranged around the top of the intermediate plate 20, and a flower-shaped sealing ring 25 is tightly fitted in the stepped groove 24.

[0041] Specifically, by combining the reasonable dimensions of the pump housing 1, diaphragm 15, and pump housing bracket 2, and the secondary protection of the flower-shaped sealing ring 25, the water leakage is achieved through the strong locking of the fastening screws (leaking out of the pump body through the flower-shaped sealing ring 25); the water leakage is achieved through the reasonable dimensions of the piston 19, diaphragm 15, and bearing frame 16, and the strong locking of the fastening screws (leaking through the diaphragm to the bearing frame and the front cover). The dimensions of the mounting seat 17 and the circular through hole 14 are reasonably designed to ensure that when the pump is working, there will be no collision and noise, and it can also support the diaphragm 15 to ensure that the diaphragm 15 will not collapse or break. When the pump is working, the piston 19 and the inner wall of the water inlet chamber 21 of the intermediate plate 20 cannot collide.

[0042] In some specific embodiments, the transverse cross-section of the sound insulation cavity 5 is a circular structure.

[0043] In some specific embodiments, the sound insulation cavity 5 is disposed on the bottom wall of the pump casing 1 , and the sound insulation cavity 5 extends along the bottom wall of the pump casing 1 into the pump casing 1 to the top of the pump casing 1 .

[0044] Specifically, the circular cross-section has superior sound absorption and sound insulation properties in acoustics. Compared with other shapes, the circle can disperse sound waves more evenly, reduce the reflection and resonance of sound, and thus effectively reduce the noise level. By designing the cross-section of the sound insulation cavity 5 to be circular, the effectiveness of the sound insulation cotton can be maximized, and the overall noise reduction effect can be further improved. The circular cross-section has high structural strength and stability, and can better withstand the pressure and vibration generated during the operation of the pump head. Setting the sound insulation cavity 5 to a circular cross-section helps to improve the overall rigidity of the pump casing, reduce noise and structural fatigue caused by vibration, and extend the service life of the pump head. The design of the sound insulation cavity 5 extending from the bottom wall of the pump casing 1 to the inner top of the pump casing 1 makes full use of the vertical space inside the pump casing. This layout not only saves lateral space, but also enables the sound insulation material to cover a larger area, forming a more complete sound insulation barrier, and further improving the sound insulation effect. The circular cross-section has lower resistance in fluid dynamics, which is conducive to the smooth passage of water. By designing the sound insulation cavity 5 to have a circular cross section, the turbulence and resistance of the water flow inside the pump housing can be reduced, the efficiency and performance of the pump can be improved, and the noise generated by unstable water flow can be reduced.

[0045] In some specific embodiments, a support plate is provided in the sound insulation cavity 5, and the support plate includes:

[0046] A first sound insulation board 8, which is disposed in the middle of the sound insulation cavity 5, and the distance between the first sound insulation board 8 and the top wall of the sound insulation cavity 5 is the same as the distance between the first sound insulation board 8 and the bottom wall of the sound insulation cavity 5;

[0047] The second sound insulation board 9 is symmetrically arranged on both sides of the first sound insulation board 8 with the first sound insulation board 8 as the axis, and a plurality of second sound insulation boards 9 are arranged at intervals along the first sound insulation board 8, one end of the second sound insulation board 9 is fixedly connected to the inner wall of the sound insulation cavity 5, and the other end of the second sound insulation board 9 is fixedly connected to the first sound insulation board 8, and the sound insulation cotton is arranged between adjacent second sound insulation boards 9.

[0048] Specifically, by arranging multiple layers of sound insulation boards in the sound insulation cavity 5, sound waves can be effectively separated and absorbed. The first sound insulation board 8 is located in the middle part, with the same distance from the top wall and the bottom wall, forming a balanced sound insulation barrier. The second sound insulation board 9 is symmetrically arranged along the first sound insulation board 8 and is arranged at intervals on both sides thereof. This layout can further disperse and attenuate the sound wave energy and improve the overall sound insulation effect. The sound insulation cotton is filled between the adjacent second sound insulation boards 9, which not only increases the surface area of ​​the sound absorbing material, but also improves the sound absorption efficiency. The sound insulation cotton can effectively absorb and dissipate the sound waves passing through the sound insulation board, reduce reflections and echoes, and thus reduce the noise level. The presence of the support plate enhances the structural integrity and stability of the sound insulation cavity. The first sound insulation board 8 and the second sound insulation board 9 are interconnected and fixed to the inner wall of the sound insulation cavity to form a sturdy support frame. This structure can withstand greater internal pressure and external impact, and prolong the service life of the pump head. The design of the support plate helps to reduce the vibration transmission generated when the pump head is running. By fixing the sound insulation board in a specific position, the propagation path of the vibration can be effectively suppressed, and the noise and mechanical wear caused by vibration can be reduced. The combined design of the support plate and the sound insulation cotton is relatively simple, easy to manufacture and install. The modular structure is also convenient for later maintenance and replacement, reducing maintenance costs and time.

[0049] In some specific embodiments, the transverse cross-section of the first sound insulation board 8 is a circular structure.

[0050] In some specific embodiments, a threaded hole 10 is further provided on the bottom wall of the pump housing 1 , and six threaded holes 10 are provided in a circular array with the center of the pump housing 1 as the axis.

[0051] In some specific embodiments, two second sound insulation cavities 11 are symmetrically arranged on both sides of the threaded hole 10 with the threaded hole 10 as an axis.

[0052] In some specific embodiments, an arc-shaped groove 12 is provided on the side wall of the pump housing 1 corresponding to the threaded hole 10 , and the threaded hole 10 is connected to the inside of the arc-shaped groove 12 by extending toward the top of the pump housing 1 .

[0053] In some specific embodiments, the arc-shaped groove 12 coincides with the axis of the threaded hole 10 .

[0054] In some specific embodiments, the transverse cross-section of the sealing gasket 6 is the same as the transverse cross-section of the bottom wall of the pump casing 1 , and a plurality of through holes 13 are provided on the sealing gasket 6 corresponding to the plurality of threaded holes 10 , so that the sealing gasket 6 is fittedly connected to the bottom wall of the pump casing 1 .

[0055] Specifically, by providing threaded holes 10 on the bottom wall of the pump casing 1 and arranging them in a circular array, the overall strength and stability of the pump casing can be increased. This layout can evenly distribute the stress points and reduce structural deformation or damage caused by excessive local pressure. The design of the threaded holes 10 allows the pump head to be easily fixed in place by screws or other fasteners, simplifying the installation process. At the same time, this design also facilitates subsequent maintenance and replacement work, reducing the difficulty and time cost of operation. The sealing gasket 6 is tightly connected to the bottom wall of the pump casing 1 to ensure a good sealing effect. The through hole 13 on the sealing gasket 6 corresponds to the threaded hole 10, which not only ensures the sealing, but also provides additional support points, enhancing the overall sealing reliability.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
