Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, and in particular to a water pump device and water treatment equipment. Background Technology

[0002] In water treatment equipment, especially in drinking water terminals, water pumps serve as the core power component, driving water flow to perform functions such as filtration and transportation. Since water pumps inevitably vibrate during operation, this vibration not only causes resonance in the entire equipment through structural transmission but also generates significant noise, affecting the stability of equipment operation and the quietness of the environment. To mitigate this problem, existing technologies typically incorporate vibration damping components, such as rubber pads or elastic supports, between the water pump and the equipment body to absorb vibration energy and reduce noise propagation.

[0003] However, existing anti-vibration structures often focus only on vibration reduction performance, neglecting the relative positional stability between the anti-vibration components and the pump body. In actual use, due to the continuous alternating loads generated during pump operation, relative rotation or displacement can easily occur between the anti-vibration components and the pump body, leading to loose connections, seal failure, and even leaks in pipe joints or electrical connection faults. Especially in the confined space of a drinking water terminal, this relative movement can also cause interference with other components, affecting the overall reliability of the machine.

[0004] Furthermore, existing anti-vibration structures often rely on additional fasteners such as screws and clamps to restrict the relative movement between the anti-vibration components and the pump body. This not only increases assembly complexity but also raises the difficulty of disassembly and maintenance. In the absence of effective anti-rotation measures, even with anti-vibration components made of high-damping materials, it is still difficult to fundamentally solve the structural stability problems caused by torsion or slippage, thus limiting the application of water pump units in high-reliability water treatment equipment.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In water treatment equipment, especially in drinking water terminals, water pumps serve as the core power component, driving water flow to perform functions such as filtration and transportation. Since water pumps inevitably vibrate during operation, this vibration not only causes resonance in the entire equipment through structural transmission but also generates significant noise, affecting the stability of equipment operation and the quietness of the environment. To mitigate this problem, existing technologies typically incorporate vibration damping components, such as rubber pads or elastic supports, between the water pump and the equipment body to absorb vibration energy and reduce noise propagation.

[0022] However, existing anti-vibration structures often focus only on vibration reduction performance, neglecting the relative positional stability between the anti-vibration components and the pump body. In actual use, due to the continuous alternating loads generated during pump operation, relative rotation or displacement can easily occur between the anti-vibration components and the pump body, leading to loose connections, seal failure, and even leaks in pipe joints or electrical connection faults. Especially in the confined space of a drinking water terminal, this relative movement can also cause interference with other components, affecting the overall reliability of the machine.

[0023] Furthermore, existing anti-vibration structures often rely on additional fasteners such as screws and clamps to restrict the relative movement between the anti-vibration components and the pump body. This not only increases assembly complexity but also raises the difficulty of disassembly and maintenance. In the absence of effective anti-rotation measures, even with anti-vibration components made of high-damping materials, it is still difficult to fundamentally solve the structural stability problems caused by torsion or slippage, thus limiting the application of water pump units in high-reliability water treatment equipment.

[0024] Based on this, see Figures 1 to 6As shown, this utility model embodiment provides a water pump device 10, which includes a pump body 100, a first shock absorber 200, and a positioning structure 300; the first shock absorber 200 is sleeved on the pump body 100 and is used to connect with external components; the positioning structure 300 includes a positioning protrusion 310 and a positioning groove 320, which are engaged; wherein, either the positioning protrusion 310 or the positioning groove 320 is provided on the pump body 100, the other of the positioning protrusion 310 and the positioning groove 320 is provided on the first shock absorber 200, and the positioning structure 300 is provided on the outer peripheral wall of the pump body 100.

[0025] In the water pump device 10 of this embodiment, a positioning structure 300 is provided between the pump body 100 and the first shock absorber 200. The positioning structure 300 includes a positioning protrusion 310 and a positioning groove 320 that are engaged with each other. The two are respectively provided on the outer peripheral wall of the pump body 100 and the first shock absorber 200. This allows the first shock absorber 200 to effectively limit its relative rotation with the pump body 100 while realizing the vibration reduction function, thus effectively improving the vibration reduction effect.

[0026] Specifically, the positioning protrusion 310 can be disposed on the outer peripheral wall of the pump body 100, while the positioning groove 320 is correspondingly disposed on the inner wall of the first shock absorber 200; or, the positioning groove 320 can be disposed on the outer peripheral wall of the pump body 100, while the positioning protrusion 310 can be disposed on the upper part of the first shock absorber 200. Both of the above arrangements can achieve circumferential limiting between the pump body 100 and the first shock absorber 200, preventing relative rotation between the two during pump operation.

[0027] Furthermore, the number of positioning structures 300 can be one, two, or more, without any specific limitation. When multiple sets of positioning structures 300 are provided, they can be evenly distributed along the circumference of the pump body 100. For example, when two positioning protrusions 310 are provided, they can be arranged symmetrically at 180°; when three are provided, they can be evenly distributed at 120°, and so on. Preferably, multiple sets of positioning structures 300 are evenly distributed along the circumference of the pump body 100. Correspondingly, the number and position of the positioning grooves 320 correspond one-to-one with the positioning protrusions 310. By providing multiple sets of positioning structures 300, not only can the reliability of circumferential positioning be improved, but local stress can also be distributed, avoiding local deformation or wear of the first shock absorber 200 due to excessive force at a single point, thereby extending its service life. In addition, the arrangement of multiple positioning structures 300 also helps to improve guidance during the assembly process and reduce assembly errors.

[0028] The first shock absorber 200 can be made of elastic polymer materials, such as silicone rubber, nitrile rubber, polyurethane, or thermoplastic elastomers. These materials not only have good vibration damping performance but also a certain structural strength to support the stable fit of the positioning structure 300. In some embodiments, the first shock absorber 200 can also adopt a composite structure of metal and elastomer, such as covering an elastic material around a metal frame, to achieve both rigid support and vibration absorption functions. The outer contour of the first shock absorber 200 can be designed as cylindrical, square, or polygonal to fit the internal installation space of the water treatment equipment 1 and connect to external components through its outer surface. The connection method can include snap-fit, adhesive, screw fastening, or interference fit, depending on the overall structural layout and maintenance requirements.

[0029] In one embodiment, the outer wall of the pump body 100 is provided with a flange structure 111, and the flange structure 111 and the outer surface of the pump body 100 form a positioning groove 320, and the positioning protrusion 310 is connected to the first shock absorber 200.

[0030] By forming a positioning groove 320 on the outer surface of the pump body 100 to engage with a positioning protrusion 310 on the first shock absorber 200, the positioning protrusion 310 and the positioning groove 320 can be positioned and engaged after the pump body 100 and the first shock absorber 200 are engaged. This structural design allows the pump body 100 to be circumferentially limited by the positioning protrusion 310 embedding into the positioning groove 320 when installed on the first shock absorber 200, thereby effectively preventing the pump body 100 from rotating relative to the first shock absorber 200.

[0031] Specifically, the flange structure 111 can be continuously arranged along the circumference of the pump body 100, or it can be segmented into multiple arc-shaped segments to adapt to different installation spaces or manufacturing process requirements. The cross-sectional shape of the positioning groove 320 can be rectangular, trapezoidal, or dovetail-shaped, and correspondingly, the cross-sectional shape of the positioning protrusion 310 matches it to ensure that the locking structure has sufficient shear resistance when subjected to vibration or torque. For example, when the positioning groove 320 is trapezoidal, its two inclined surfaces can form a self-locking effect on the positioning protrusion 310, maintaining a stable locking state even when subjected to external disturbances during the operation of the pump body 100, thus preventing loosening.

[0032] The positioning protrusion 310 can be integrally formed into the first anti-vibration component 200, or it can be fixedly connected to the first anti-vibration component 200 by fasteners (such as screws, pins, etc.). The integral forming method can reduce assembly steps and improve the overall structure; while the fastener connection facilitates later maintenance or replacement. The first anti-vibration component 200 can be made of elastic materials such as rubber, polyurethane, or silicone. It can not only absorb the vibration energy generated during the operation of the pump body 100 and reduce the vibration amplitude transmitted to the mounting base, but also achieve circumferential constraint on the pump body 100 through the cooperation of the positioning protrusion 310 and the positioning groove 320, avoiding relative rotation caused by vibration, thereby improving the operational stability and reliability of the entire pumping system.

[0033] Specifically, the number of flange structures 111 is at least two, and two adjacent flange structures 111 are spaced apart to form a positioning groove 320.

[0034] To effectively limit and guide the positioning protrusion 310, the number of flange structures 111 is preferably two or more, such as three, four or more, to form multiple positioning grooves 320 in the circumferential or axial direction, thereby improving the positioning stability and torsional resistance during assembly. When the number of flange structures 111 is only one, it is impossible to form a closed or semi-closed positioning groove 320, making it difficult to provide effective limiting for the positioning protrusion 310. This may cause relative displacement between the pump body 100 and the first anti-vibration component 200 during operation, affecting the stability of the overall structure.

[0035] In this embodiment, after the flange structures 111 are spaced apart, a positioning groove 320 can be formed between two adjacent flange structures 111. The width, depth, and shape of the positioning groove 320 can be designed to match the size of the positioning protrusion 310 to ensure that the two can fit tightly together. For example, the cross-section of the positioning groove 320 can be rectangular, trapezoidal, or arc-shaped, and correspondingly, the cross-section of the positioning protrusion 310 also adopts a matching shape, thereby achieving a good fitting effect during assembly and preventing loosening or misalignment under vibration or impact conditions. In addition, the spacing between the flange structures 111 can be adjusted according to the actual assembly space and vibration protection requirements. If the spacing is too large, the positioning groove 320 will not provide sufficient constraint on the positioning protrusion 310, while if the spacing is too small, it may affect the ease of assembly or cause stress concentration.

[0036] After the pump body 100 is assembled with the first anti-vibration component 200, the positioning protrusion 310 can be positioned by the two flange structures 111. Specifically, the positioning protrusion 310 is embedded in the positioning groove 320 formed by adjacent flange structures 111, thereby limiting the displacement of the pump body 100 relative to the first anti-vibration component 200 in the radial direction. This structure not only simplifies the assembly process, eliminating the need for additional positioning pins or screws, but also effectively suppresses relative sliding caused by vibration during the operation of the pump body 100, improving the reliability and service life of the overall structure. At the same time, since the flange structure 111 and the pump body 100 are integrally formed or firmly connected by welding, screwing, or other methods, their structural strength is high, capable of withstanding large assembly forces and operating loads, ensuring the long-term effectiveness of the positioning function.

[0037] Specifically, the positioning protrusion 310 extends along the axial direction of the pump body 100.

[0038] This design limits the relative rotation between the pump body 100 and the first anti-vibration member 200 in the circumferential direction. The axially extending structure of the positioning protrusion 310 allows it to be embedded or fitted into the corresponding axial positioning groove 320. Thus, when the pump body 100 is subjected to circumferential torque or vibration, shear force is transmitted through the contact surface between the positioning protrusion 310 and the first anti-vibration member 200, effectively preventing relative rotation between the two in the circumferential direction. This structure not only improves the connection stability between the pump body 100 and the first anti-vibration member 200 but also avoids problems such as loosening of the connection, seal failure, or structural fatigue caused by relative rotation.

[0039] Furthermore, the water pump device 10 also includes a second shock absorber 400. The pump body 100 includes a pump body 110 and a pump port 120. The first shock absorber 200 is sleeved on the pump body 110, and the second shock absorber 400 is sleeved on the pump port 120 and is used to seal the pump port 120 and the external pipeline.

[0040] By setting a second shock absorber 400 to cooperate with the pump body 100, the second shock absorber 400 can not only seal the connection between the pump body 100 and the external pipeline, but also absorb the impact energy generated by fluid pulsation or mechanical vibration at the pump port 120 during the operation of the water pump, thereby reducing the transmission of vibration to the external pipeline.

[0041] In this embodiment, the first shock absorber 200 connects the pump body 110 to external components and achieves a shock-absorbing effect, while the second shock absorber 400 seals the pump port 120 to the external pipeline and simultaneously achieves a shock-absorbing effect. Specifically, the second shock absorber 400 can take the form of an elastic sealing ring, a rubber sleeve, or a composite sealing assembly with a buffer structure. For example, the second shock absorber 400 may include an inner sealing ring and an outer damping sleeve. The inner sealing ring is used to fit against the end faces of the pump port 120 and the external pipeline to form a seal, while the outer damping sleeve is made of elastic material to buffer the relative displacement between the pump port 120 and the external pipeline. This structure ensures the reliability of the connection seal and effectively isolates the vibration transmission path, preventing seal failure or pipeline loosening due to vibration.

[0042] Furthermore, the material of the second anti-vibration component 400 can be a water-resistant, aging-resistant, and elastic polymer material, such as nitrile rubber, fluororubber, or polyurethane, depending on the properties of the medium transported by the pump body 100 and the operating environment temperature. When the second anti-vibration component 400 adopts a structural design with axial and radial flexibility, it can also compensate for minor alignment deviations between the pump port 120 and the external pipeline during installation or operation, further improving the stability of the connection and the sealing life. Since the pump port 120 is usually a key interface for fluid output or input, if its vibration is not effectively suppressed, it can easily cause resonance in the pipeline system or fatigue cracking of the sealing interface. Therefore, the installation of the second anti-vibration component 400 not only ensures the system's sealing performance but also improves the overall stability and reliability of the machine's operation.

[0043] Specifically, the second shock absorber 400 includes a sealing part 410 and a positioning part 420. The sealing part 410 is connected to the positioning part 420, and the outer diameter of the positioning part 420 is larger than that of the sealing part 410. The sealing part 410 is used to be inserted into an external pipeline, and the positioning part 420 is used to abut against the pump body 100 and the external components.

[0044] In this embodiment, the sealing part 410 and the positioning part 420 are connected to form a T-shaped structure. This T-shaped structure allows the second shock absorber 400 to simultaneously achieve axial positioning and radial sealing functions during assembly. The positioning part 420 contacts both the pump body 110 and the external components. Its large contact area disperses the vibration load generated during the operation of the pump body 100, effectively suppressing the transmission of vibration to the external pipeline and improving the overall system's operational stability. Simultaneously, after the sealing part 410 is inserted into the external pipeline, its outer circumferential surface fits tightly against the inner wall of the pipeline, forming a reliable sealing interface to prevent fluid leakage. Furthermore, its elastic or damping characteristics absorb high-frequency vibrations while sealing, further enhancing the shock absorption effect.

[0045] The sealing part 410 and the positioning part 420 can be manufactured as a single piece, or they can be fixed by bonding, interference fit, or fastener connection. Specifically, the sealing part 410 can be made of polymer materials such as rubber, silicone, or polyurethane with elasticity and media resistance to ensure good sealing and cushioning performance; the positioning part 420 can be made of engineering plastics or metal materials with high hardness and good dimensional stability, such as polyoxymethylene, aluminum alloy, or stainless steel, to withstand assembly preload and mechanical loads during operation. When the sealing part 410 and the positioning part 420 are made of different materials, a reliable connection between the two can be achieved through insert injection molding or secondary molding processes, balancing sealing performance and structural strength.

[0046] Furthermore, the outer wall of the sealing part 410 is provided with at least one sealing flange 411, which is used to seal the space between the sealing part 410 and the external pipeline.

[0047] Specifically, there can be one, two, or more sealing flanges 411, without any unique limitation. When multiple sealing flanges 411 are provided, they can be arranged at intervals along the axial direction of the sealing part 410, thereby forming multiple sealing barriers in the contact area between the sealing part 410 and the external pipeline, effectively improving sealing reliability and reducing the risk of media leakage. The cross-sectional shape of the sealing flange 411 can be rectangular, trapezoidal, or semi-circular, etc., and can be selected according to the structure of the sealing mating surface and the properties of the sealing medium to balance sealing performance and assembly convenience.

[0048] When there are multiple sealing parts 410, they are spaced apart along the axial direction of the sealing parts 410. Specifically, the multiple sealing parts 410 can be arranged sequentially in the axial direction of the connecting structure, and a certain distance can be set between adjacent sealing parts 410. This distance can be adjusted according to the pressure level, medium type, and installation space under actual working conditions. By setting multiple sealing parts 410, not only can the sealing path length be increased, but also, when the sealing performance of one sealing part 410 decreases due to wear or deformation, other sealing parts 410 can continue to assume the sealing function, thereby improving the redundancy and service life of the overall sealing structure. In addition, the arrangement of multiple sealing parts 410 also helps to disperse contact stress and avoid seal failure caused by local stress concentration.

[0049] In one embodiment, at least one side surface of the positioning part 420 is provided with a hollow groove 421.

[0050] By providing the perforated groove 421, when the second shock absorber 400 is connected to the pump body 100 and the external components, the second shock absorber 400 can deform towards the perforated groove 421 to ensure the sealing effect of the second shock absorber 400. Specifically, the perforated groove 421 provides a local flexible area for the positioning part 420, so that when the second shock absorber 400 is subjected to external assembly pressure or compressive force generated by vibration during operation, the positioning part 420 can undergo controllable elastic deformation along the direction of the perforated groove 421, thereby avoiding the problem of increased sealing surface gap or sealing failure caused by rigid contact.

[0051] The hollow groove 421 can be rectangular, circular, fan-shaped, or irregularly shaped, specifically designed according to the installation space of the second shock absorber 400 and the expected deformation direction. For example, when the hollow groove 421 is a rectangular groove, its length can extend along the thickness direction of the positioning part 420 to enhance compressive compliance in the direction perpendicular to the sealing surface; when the hollow groove 421 is an array of multiple circular through holes, multi-directional uniform deformation can be achieved, improving the overall sealing stability. In addition, the hollow groove 421 can be provided on one side surface of the positioning part 420, or it can be provided on both opposite sides, to further improve the uniformity of deformation and the balance of the structure in a symmetrical distribution.

[0052] It should be noted that the number of perforated grooves 421 can be one, two, or more, and there is no single limitation. When multiple perforated grooves 421 are provided, each perforated groove 421 can be evenly arranged along the circumference of the positioning part 420 to disperse stress concentration and improve the adaptability of the second shock absorber 400 under complex working conditions. If perforated grooves 421 are not provided, the overall rigidity of the positioning part 420 is too high, and it is difficult to generate effective deformation under compression, which may lead to local separation of the sealing interface, thereby affecting the sealing performance. On the other hand, if the perforated grooves 421 are too large or too numerous, it may weaken the structural strength of the positioning part 420 and affect its support stability for the second shock absorber 400. Therefore, the size, number, and arrangement of the perforated grooves 421 need to be comprehensively designed in combination with the actual working conditions, material properties, and sealing requirements.

[0053] In some embodiments, the perforated grooves 421 may also be simultaneously provided on opposite axial sides of the positioning portion 420. This structural design allows the perforated grooves 421 on both sides to create localized stress concentrations on the sealing element or sealing area when the positioning portion 420 contacts the mating component, thereby improving the tightness of the sealing interface. When the perforated grooves 421 are provided on both axial sides of the positioning portion 420, the sealing element can simultaneously embed into the perforated grooves 421 on both sides during the compression deformation process, forming a double sealing path and effectively blocking the leakage channel of the medium along the axial direction. In addition, this structure can also compensate for changes in the mating clearance caused by processing errors or thermal expansion to a certain extent, improving the adaptability of the sealing structure under different working conditions.

[0054] Furthermore, the sealing part 410 is provided with a first guide slope 412, which is located at the outer edge of the end of the sealing part 410.

[0055] The first guide slope 412 provides initial guidance for the relative position of the sealing part 410 and the external pipeline during insertion and mating, reducing assembly resistance caused by misalignment and thus improving the smoothness and efficiency of the installation process. Specifically, when the external pipeline approaches the sealing part 410 axially, its port edge first contacts the first guide slope 412. This slope, through its inclined structure, gradually adjusts the insertion direction of the external pipeline to align with the axis of the sealing part 410, avoiding damage to the sealing surface or improper assembly due to initial insertion angle deviation, thereby helping to ensure the accuracy and reliability of the sealing fit.

[0056] The inclination angle of the first guide slope 412 can be adjusted according to actual assembly requirements, such as 15°, 30°, 45°, or 60°. The specific angle is determined comprehensively based on factors such as the structural dimensions of the sealing part 410, material rigidity, and the insertion force requirements of the external pipeline; no single limitation is set here. If the inclination angle is too small, the guiding effect will be limited, making effective correction difficult; if the inclination angle is too large, it may lead to a reduction in the contact area between the slope and the external pipeline, resulting in localized stress concentration and affecting structural strength or sealing performance. Therefore, it is preferable to control the inclination angle of the first guide slope 412 between 15° and 60° to balance guiding effect and structural stability.

[0057] In addition, the first guide slope 412 can be integrally formed with the sealing part 410, or it can be formed by subsequent machining or injection molding. Its surface can be polished or plated to reduce the coefficient of friction and further improve the smoothness of insertion.

[0058] In one embodiment, the positioning part 420 is provided with a second guide slope 422, which is located at the opening edge of the positioning part 420 and is used to guide the pump port 120 into the positioning part 420.

[0059] With this configuration, when the pump port 120 is connected to the second anti-vibration component 400, the second guide ramp 422 can contact and slide with the outer periphery of the pump port 120, guiding the pump port 120 smoothly into the positioning part 420 along a predetermined path, thereby effectively improving the connection convenience and installation accuracy between the pump port 120 and the second anti-vibration component 400.

[0060] Specifically, the inclination angle of the second guide slope 422 can be optimized according to the outer contour of the pump port 120 and the assembly path. For example, the included angle between the second guide slope 422 and the axis of the positioning part 420 can be 15°, 20°, 25°, 30° or 35°, depending on the actual assembly space and guiding requirements, and is not limited here. When the included angle is less than 15°, the guiding stroke is too long, which may lead to an increase in the overall structural size, which is not conducive to a compact layout; when the included angle is greater than 35°, the guiding effect is weakened, and the pump port 120 is prone to deflection or jamming in the initial contact stage, affecting the smoothness of assembly and the accuracy of positioning.

[0061] Furthermore, the second guide ramp 422 can be continuously arranged along the entire circumference of the opening of the positioning part 420, or multiple guide segments can be arranged at intervals in a local area of ​​the opening. For example, the second guide ramp 422 can be set as two, three, or four, evenly distributed along the circumference, so as to reduce the processing difficulty and material consumption while ensuring the guiding function. When multiple second guide ramps 422 are set, each guide ramp can contact different positions on the outer wall of the pump port 120, forming multi-point guidance, which helps to initially correct the posture of the pump port 120 during the assembly process, reduce deflection or misalignment caused by single-point contact, and thus improve the consistency and repeatability of the overall assembly.

[0062] Furthermore, the surface of the second guide ramp 422 can be polished or coated with a friction-reducing coating to reduce frictional resistance when in contact with the pump port 120, further improving assembly smoothness. The material of the second guide ramp 422 can be integrally formed with the positioning part 420, or it can be made of embedded wear-resistant materials, such as engineering plastics or metal alloys, to balance structural strength and wear resistance. Through the above structural design, the second guide ramp 422 not only realizes the mechanical guiding function of the pump port 120, but also significantly optimizes the docking process between the pump port 120 and the second anti-vibration component 400 without adding extra assembly steps, improving the overall assembly efficiency and connection reliability.

[0063] The present invention also provides a water treatment device 1, which includes a body 20 and a water pump device 10 in any of the above embodiments; the water pump device 10 is connected to the body 20, and the first shock absorber 200 is at least partially located between the body 20 and the water pump device 10.

[0064] It is understood that by providing the water pump device 10 in any of the above embodiments, the water treatment equipment 1 of this embodiment can effectively reduce the overall noise and structural fatigue caused by the vibration of the water pump transmitted to the machine body 20 during operation, thereby improving the stability and service life of the equipment.

[0065] Specifically, the body 20 is provided with a connecting post 201, the outer peripheral wall of the connecting post 201 is provided with a stepped groove 2011, the first shock absorber 200 is provided with a connecting hole 221, the connecting post 201 is inserted into the connecting hole 221, and the first shock absorber 200 is at least partially located in the stepped groove 2011.

[0066] By setting the stepped groove 2011 to cooperate with the first shock absorber 200, the shock absorber function can be realized, and the relative position between the connecting column 201 and the first shock absorber 200 can be effectively limited. This avoids excessive deformation or displacement of the silicone first shock absorber 200 due to pressure during the locking process, thereby improving assembly stability and structural reliability.

[0067] During assembly, the connecting post 201 is inserted into the connecting hole 221. At this time, the stepped end face of the stepped groove 2011 abuts against one side surface of the first shock absorber 200 to axially position the fit between the two, preventing the first shock absorber 200 from moving axially along the connecting post 201 under stress. Subsequently, the fastener is passed through the connecting hole 221 and connected to the connecting post 201 to complete the overall assembly. The fastener can be a screw, pin, or bolt, etc., and the specific type can be selected according to the actual assembly space, load requirements, and disassembly frequency.

[0068] Specifically, the first shock absorber 200 includes a shock absorber sleeve 210 and a connecting ear 220, with the connecting ear 220 connected to the outer wall of the shock absorber sleeve 210. The shock absorber sleeve 210 is fitted onto the pump body 110, with its inner wall fitting against the outer surface of the pump body 110 to achieve wrapping and cushioning of the pump body 110.

[0069] The shock-absorbing sleeve 210 can be made of elastic materials, such as rubber, silicone, or polyurethane. These materials have good shock absorption performance and a certain deformation recovery capability, enabling them to absorb vibration energy during pump operation and reduce the vibration intensity transmitted to the external structure. The connecting lug 220 extends outward from the shock-absorbing sleeve 210. Its structure can be plate-shaped, block-shaped, or strip-shaped, and the specific shape can be adjusted according to the installation space and stress requirements. The connecting lug 220 is provided with a connecting hole 221, which is used to mate with the connecting post 201 to achieve a fixed connection between the first shock absorber 200 and the external support structure or mounting base. The diameter and position of the connecting hole 221 must match the connecting post 201 to ensure the stability and reliability of the assembly. In practical applications, the number of connecting lugs 220 can be one, two, or more; no single limitation is made here. Setting multiple connecting lugs 220 helps improve the overall installation stability of the first shock absorber 200 and makes the load distribution more uniform, avoiding structural fatigue or failure caused by local stress concentration. In addition, the connection between the earpiece 220 and the shockproof sleeve 210 can be a one-piece molded structure, or it can be fixed by means of bonding, vulcanization or mechanical connection. The specific connection method can be selected according to the material characteristics and process conditions.
