Description

Technical Field

[0001] This invention relates to the field of media pumping technology, and more specifically, to a support mechanism, a valve core assembly, a booster pump, and a water purifier. Background Technology

[0002] As users demand higher flow rates from liquid pumping devices, it is inevitable that the flow rate and lifespan of booster pumps, the core component of these devices, will increase. Based on market demand, the current demand for booster pump flow rates is evolving from 600G to 800G and even 1200G.

[0003] In related technologies, as the flow rate increases, the heating phenomenon of the motor and bearings becomes more pronounced. The internal bearing support of the diaphragm pump is in direct contact with the diaphragm, accelerating the heat transfer rate from the bearing support to the diaphragm. However, high temperatures shorten the service life of the diaphragm, a critical component of the pump, leading to a sharp increase in the diaphragm pump failure rate.

[0004] Therefore, designing a valve core assembly that can overcome the above-mentioned technical defects has become an urgent technical problem to be solved. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, the first aspect of the present invention proposes a support mechanism.

[0007] A second aspect of the present invention provides a valve core assembly.

[0008] A third aspect of the present invention provides a booster pump.

[0009] The fourth aspect of this invention provides a water purifier.

[0010] In view of the above, the first aspect of the present invention provides a support mechanism, the support mechanism comprising: a base including a guide groove; a heat-insulating member disposed on the base, the heat-insulating member being partially embedded in the guide groove, the heat-insulating member being used to support a diaphragm and to drive the diaphragm to move; wherein, in the depth direction of the guide groove, the cross-sectional area of ​​the guide groove gradually decreases.

[0011] This application defines a support mechanism for a booster pump. The support mechanism includes a base for connecting a diaphragm on the booster pump and driving the diaphragm to move within the booster pump. The diaphragm is the core component of the booster pump. The base connects the diaphragm and a drive assembly. The drive assembly drives a bearing on the base to swing, causing the diaphragm to swing within the booster pump. The swinging diaphragm can change the size of the pumping chamber on the opposite side of the base. When the swinging diaphragm enlarges the pumping chamber, negative pressure forces liquid into the pumping chamber. Conversely, when the swinging diaphragm shrinks the pumping chamber, previously pumped liquid is forced out of the pumping chamber, thereby meeting the liquid pumping requirements.

[0012] In related technologies, due to product demands, the required pumping flow rate of booster pumps is increasing, with the flow rates of booster pumps on the market developing from 600G, 800G to 1200G, representing a significant increase. One way to increase pumping flow rate is to accelerate the diaphragm's movement frequency, but this high-speed efficiency enhancement method generates a large amount of heat during operation, causing the base and the diaphragm in contact with the base to heat up, with actual temperatures reaching around 70℃. However, diaphragms are mostly made of elastic materials such as rubber, and high temperatures have an irreversible impact on their performance, leading to rapid diaphragm aging. This results in technical problems such as short diaphragm lifespan, high failure rate, and poor booster pump reliability.

[0013] To address this, this application incorporates a heat-insulating component within the support structure. Specifically, the heat-insulating component is fixed to the base and supports the diaphragm. After assembly, the heat-insulating component is positioned between the base and the diaphragm, maintaining contact with the diaphragm. As the heat-insulating component moves with the base, the diaphragm in contact with it deforms. The heat-insulating component possesses excellent thermal insulation properties, effectively reducing heat transfer efficiency between the base and the diaphragm. Specifically, the heat-insulating component can be made of PA6+30GF (Nylon 66+30% glass fiber) material, or it can be made of thermal insulation materials such as ceramics. This technical solution does not impose strict limitations on the material of the heat-insulating component, as long as it meets the thermal insulation requirements.

[0014] By placing a heat-insulating component between the base and the diaphragm, the heat transfer efficiency from the base to the diaphragm can be effectively reduced, thereby lowering the diaphragm temperature during operation and preventing high-temperature damage. This solves the technical problems existing in the aforementioned related technologies. Furthermore, it optimizes the valve core assembly structure, extending the diaphragm's service life while meeting high-flow pumping requirements, reducing the failure rate of the support mechanism, and lowering the failure rate of the booster pump.

[0015] Specifically, in this technical solution, the base and the heat-insulating component are separate structures. This separate design allows for the selection of a high-strength metal material for the base, ensuring its ability to drive the diaphragm at high speeds for extended periods and reducing the base's failure rate. Furthermore, the heat insulation performance of the heat-insulating component can be adjusted by selecting and replacing it with different materials. This allows for the selection of the appropriate heat-insulating component based on the pumping flow requirements of the booster pump, thereby reducing the cost of the support structure while still meeting insulation needs.

[0016] Based on this, a guide groove is provided on the base. The shape of the guide groove is adapted to the outer contour shape of some heat-resistant components. Embedding some heat-resistant components into the guide groove completes the positioning and assembly of the heat-resistant components on the base, ensuring the positioning accuracy of the heat-resistant components and guaranteeing that the base and heat-resistant components can drive the diaphragm to swing precisely. Specifically, the cross-sectional area of ​​the guide groove can be determined by cutting the guide groove with a plane perpendicular to its depth direction. Furthermore, the cross-sectional area of ​​the guide groove gradually decreases along its depth direction, forming a guide groove that tapers from top to bottom. By limiting the taper of the guide groove along its depth direction, a funnel-shaped guide groove can be formed, which serves as a guide, allowing some heat-resistant components to slide to their predetermined installation position after being placed in the guide groove, thereby reducing the probability of incorrect installation of the heat-resistant components. This achieves the technical effects of optimizing the positioning structure of the heat-resistant components, improving the positioning accuracy of the heat-resistant components, and increasing the yield rate of the support mechanism.

[0017] In addition, the support mechanism provided by the present invention may also have the following additional technical features:

[0018] In the above technical solution, the base also includes a blind hole, and the support mechanism also includes a guide member disposed in the blind hole, including a guide slope opposite to the side wall of the blind hole; the guide slope and the blind hole enclose a guide groove.

[0019] In this technical solution, the base structure is further defined. Specifically, a blind hole is provided on the surface of the base facing the heat-insulating component, and a guide component is provided in the blind hole. A guide slope is formed on the periphery of the guide component. The guide slope, the bottom wall of the blind hole, and the side wall of the blind hole together form a guide groove. The guide slope is inclined relative to the side wall of the blind hole, thus forming a tapering guide groove. After the heat-insulating component is assembled, part of the heat-insulating component is embedded in and fills the guide groove to accurately position the heat-insulating component and prevent it from wobbling relative to the base during operation. This improves the control accuracy of the diaphragm and precisely controls the liquid pumping efficiency.

[0020] In any of the above technical solutions, the guide is a frustum, and the bottom surface of the frustum is connected to the bottom wall of the blind hole.

[0021] In this technical solution, following the aforementioned technical solution, the shape of the guide component is defined. Specifically, the guide component is a frustum, with the bottom surface of the frustum connected to the bottom wall of the blind hole, the top surface facing the heat-insulating component, and the multiple sides of the frustum serving as guide ramps.

[0022] In this design, both the guide groove and the guide component have regular polygonal cross-sectional shapes. For example, the guide groove may have an equilateral triangle cross-section, with the corresponding guide component being a triangular frustum; the guide groove may have a regular quadrilateral cross-section, with the guide component being a quadrangular frustum; or the guide groove may have a regular octagonal cross-section, with the guide component being an octagonal frustum. During operation, the peripheral surface of the frustum abuts against the sidewall of the guide groove to prevent the heat-insulating component from rotating relative to the positioning part. This technical solution does not impose rigid limitations on the shapes of the guide groove and the guide component, as long as the aforementioned positioning requirements are met.

[0023] In any of the above technical solutions, the guide component is a hexagonal truncated pyramid.

[0024] In this technical solution, the guide groove has a regular hexagonal cross-section, and the corresponding guide component has a hexagonal truncated pyramid cross-section. By inserting part of the heat-insulating component between the hexagonal truncated pyramid and the guide groove, the heat-insulating component can be snapped onto the positioning part. The hexagonal truncated pyramid has a through hole for the connector to connect the heat-insulating component and the base.

[0025] Specifically, the heat-insulating component and the guide groove are interference-fitted. By limiting this interference fit, a tight connection between the base and the heat-insulating component can be achieved, thereby improving the positioning accuracy of the heat-insulating component and preventing it from misaligning relative to the positioning part or even coming off the positioning part during operation. This, in turn, achieves the technical effect of improving the structural stability and reliability of the support mechanism.

[0026] In any of the above technical solutions, there are N guide grooves, which are evenly distributed on the base; where N is an integer greater than 2.

[0027] In this technical solution, the base is provided with N positioning parts, and each positioning part is provided with a guide groove. Based on this, the distribution of the guide grooves on the base is defined. Specifically, the base has a ring-shaped structure. On the base, at least three guide grooves are evenly distributed on the same circle with the base's axis as the axis, forming a ring-shaped array of guide grooves on the body. By evenly distributing multiple guide grooves along the ring line on the body, the uniformity of the force distribution on the base can be improved, preventing damage to the diaphragm due to uneven force. This achieves the technical effect of optimizing the base structure and extending the diaphragm's service life.

[0028] In any of the above technical solutions, the base is annular, and N guide grooves are evenly distributed on the same circle with the axis of the base as the axis.

[0029] This technical solution specifies the distribution of the guide grooves on the base. Specifically, the base has a ring-shaped structure. At least three guide grooves are evenly distributed on the same circle with the base's axis as the axis, forming a ring-shaped array of guide grooves on the body. By evenly distributing multiple guide grooves along the ring line on the body, the uniformity of the force distribution on the base can be improved, preventing damage to the diaphragm due to uneven stress. This achieves the technical effect of optimizing the base structure and extending the diaphragm's service life.

[0030] In any of the above technical solutions, there are N heat-insulating components, and the N heat-insulating components are connected to the N guide grooves one by one.

[0031] This technical solution specifies the number of heat-resistant components and the correspondence between them and the guide grooves. Specifically, the number of heat-resistant components is the same as the number of guide grooves, and N guide grooves are arranged in a one-to-one correspondence with N heat-resistant components to form a ring-shaped array of N heat-resistant components on the base, which collectively support the diaphragm. By setting N heat-resistant components corresponding to N guide grooves, the contact area between the heat-resistant components and the diaphragm can be reduced while meeting the diaphragm positioning and connection requirements, thus avoiding large-area contact that could affect the diaphragm's movement range. This optimizes the support structure and improves the pumping performance of the support mechanism.

[0032] In any of the above technical solutions, the heat-insulating component includes: a body; and a rib disposed on the body, the rib being embedded in a guide groove.

[0033] In this technical solution, the structure of the heat-insulating component is defined. Specifically, the heat-insulating component includes a body and a rib. The body is located outside the guide groove and is used to support and connect the diaphragm. The top surface of the body is in contact with the diaphragm. When the driving base swings, the body pushes and pulls the diaphragm to deform it. This deformation of the diaphragm changes the size of the cavity on the side away from the base, thereby completing the extraction and pumping of liquid. The rib is set on the bottom surface of the body, and its shape matches the shape of the guide groove. During assembly, the rib is first aligned with the guide groove, and then the rib is accurately pushed into the guide groove through the guide ramp to precisely position the heat-insulating component on the base.

[0034] The positioning part has a columnar structure, and the heat-insulating component has a mounting groove whose shape matches the outer contour of the positioning part. During assembly, the positioning part is first aligned with the mounting groove, and then inserted into the mounting groove to complete the assembly of the heat-insulating component. By setting the mounting groove, a nested positioning connection structure can be formed with the positioning part and the guide groove, thereby improving the positioning accuracy of the heat-insulating component. At the same time, this nested connection structure can improve the positioning stability of the heat-insulating component, preventing misalignment or even detachment during long-term reciprocating motion. This ultimately achieves the technical effect of improving the structural stability of the support mechanism and reducing the failure rate of the support mechanism.

[0035] In any of the above technical solutions, the rib and the guide groove are interference-fitted.

[0036] In this technical solution, following the aforementioned solution, the rib and guide groove are interference-fitted. Specifically, the side of the rib facing the base is the front end of the rib, and the opposite side is the end of the rib. During assembly, after aligning the rib with the guide groove, the front end of the rib is placed on the guide ramp. Under the action of the guide ramp, the rib slides towards the bottom of the guide groove, thus completing the pre-assembly of the heat-insulating component. However, at this point, because the size of the rib is slightly larger than the size of the guide groove, the rib is not completely submerged in the guide groove. Subsequently, the rib is pressed into the guide groove using a connector to ensure that the outer surface of the rib is tightly fitted with the inner wall of the guide groove, thereby eliminating the gap between the rib and the guide groove and preventing the heat-insulating component from misaligning or even falling off during operation. This achieves the technical effects of optimizing the positioning structure of the heat-insulating component, improving the positioning accuracy of the heat-insulating component, and reducing the failure rate of the support mechanism.

[0037] In any of the above technical solutions, the heat-insulating component is detachably connected to the base.

[0038] In this technical solution, the heat-insulating component and the base are detachably connected. This detachable structure allows for modular design of both the base and the heat-insulating component, enabling the selection of heat-insulating components with corresponding insulation performance for bases with different pumping efficiencies. Furthermore, the detachable heat-insulating component allows for quick maintenance of the support structure by disassembling and replacing the component when it ages or fails, thus providing convenience for users and reducing product maintenance difficulty and costs.

[0039] In any of the above technical solutions, the support mechanism further includes: a connector, a connecting base, and a heat-insulating component.

[0040] In this technical solution, the valve core assembly is also provided with a connector. After the initial positioning of the heat-insulating component is completed by the guide groove, the heat-insulating component and the base are connected by the connector so that the base can drive the heat-insulating component and the diaphragm to swing together, thus preventing the heat-insulating component and the base from separating.

[0041] Specifically, the connector can be a screw. When a screw is selected as the connector, a first screw hole is provided on the heat-insulating component, and a raised rib is provided around the first screw hole. A second screw hole is correspondingly provided on the base, and the second screw hole is located on the guide component. The screw passes through the first screw hole and is inserted into the second screw hole to connect the heat-insulating component and the base. This structure is only one possible connector structure. Other connection structures such as snap-fit ​​slots can also be used to connect the heat-insulating component and the base. This application does not impose rigid limitations on the structure of the connector, as long as it meets the requirement of a reliable connection.

[0042] A second aspect of the present invention provides a valve core assembly, the valve core assembly comprising: a support mechanism as described in any of the above technical solutions; and a diaphragm disposed on a heat-insulating member, the heat-insulating member being located between a base and the diaphragm.

[0043] This technical solution defines a valve core assembly equipped with the support mechanism described in any of the above-mentioned technical solutions. Therefore, this valve core assembly possesses the advantages of the support mechanism in any of the above-mentioned technical solutions and can achieve the technical effects achieved by the support mechanism in any of the above-mentioned technical solutions. To avoid repetition, further details are omitted here. The diaphragm is disposed on a heat-insulating element, and the heat-insulating element is located between the base and the diaphragm. This reduces the heat transfer efficiency between the base and the diaphragm through the heat-insulating element, thereby preventing high-temperature damage to the diaphragm and extending its service life.

[0044] In any of the above technical solutions, the valve core assembly further includes: a pressing member disposed on the diaphragm and facing away from the heat-insulating member, the pressing member being connected to the heat-insulating member for pressing the diaphragm onto the heat-insulating member.

[0045] In this technical solution, the valve core assembly also includes a clamping component, which is mounted on the diaphragm. A connecting component passes through the diaphragm and connects the clamping component and the heat-insulating component. The clamping component presses the diaphragm tightly against the heat-insulating component, ensuring a close fit between the diaphragm and the top surface of the heat-insulating component, thus achieving diaphragm clamping. The diaphragm is the main working part of the booster pump. During operation, the booster pump drives the diaphragm to move, changing the size of the space divided by the diaphragm, thereby completing the extraction, pressurization, and discharge of the medium. The connecting component and clamping component accurately position the diaphragm within the booster pump, reducing the possibility of misalignment during operation. Furthermore, the clamping component ensures the diaphragm adheres tightly to the base, eliminating the gap between the first positioning surface and the diaphragm, thereby improving the diaphragm's movement accuracy and ensuring the pumping efficiency of the valve core assembly.

[0046] A third aspect of the present invention provides a booster pump, the booster pump comprising: a housing including a cavity; a valve core assembly as described in any of the above technical solutions, disposed within the cavity, a diaphragm connected to the housing, and the diaphragm separating the cavity.

[0047] This technical solution defines a booster pump equipped with the valve core assembly of any of the above technical solutions. Therefore, the booster pump has the advantages of the valve core assembly of any of the above technical solutions and can achieve the technical effects achieved by the valve core assembly of any of the above technical solutions. To avoid repetition, it will not be described in detail here.

[0048] Specifically, the booster pump includes a housing, which serves as the external frame structure of the booster pump and encloses and defines a cavity. A base and a clamping element are disposed within the cavity, thereby positioning a diaphragm within the housing. The periphery of the diaphragm is connected to the inner wall of the housing to divide the cavity into two sub-cavities, with the base and clamping element located in the sub-cavities on either side of the diaphragm. When the base moves a portion of the diaphragm and the clamping element relative to the housing, the diaphragm connected to the housing is pushed and pulled, causing deformation. During the stretching process, the volume of the sub-cavity where the clamping element is located increases, allowing the booster pump to draw media into this sub-cavity. When the diaphragm is pushed by the base towards the clamping element, the volume of the sub-cavity where the clamping element is located decreases, allowing the media within this sub-cavity to be expelled from the booster pump. This achieves the pumping of media by the booster pump.

[0049] In any of the above technical solutions, the housing further includes an inlet and an outlet, which are connected to the cavity on the side of the diaphragm away from the base. The booster pump further includes a drive assembly connected to the base for driving the base to swing relative to the housing.

[0050] In this technical solution, the housing is provided with an inlet and an outlet for the medium to enter and exit. Both the inlet and outlet are connected to a sub-cavity on one side of the diaphragm. The base and drive unit are disposed in the sub-cavity on the side opposite to the inlet and outlet. Specifically, the drive assembly is fixed to the housing, and the base connects the drive assembly and the diaphragm. When the booster pump is working, the drive assembly drives the base and the clamping member to move relative to the housing, thereby achieving the intake and discharge of the medium by pushing and pulling the diaphragm.

[0051] In any of the above technical solutions, the drive assembly includes: a drive component, including a drive shaft; an eccentric wheel, sleeved on the drive shaft; and a bearing, with the inner ring of the bearing sleeved on the eccentric wheel and the outer ring of the bearing passing through the base.

[0052] In this technical solution, the structure of the drive assembly is defined. Specifically, the drive assembly includes a drive element, an eccentric wheel, and a bearing. The eccentric wheel and bearing form the transmission structure between the base and the drive element. The bearing is sleeved on the shaft of the eccentric wheel, and the base is sleeved on the outside of the bearing. During operation, the eccentric wheel rotates around a first axis, and there is a first angle between the axis of the shaft and the first axis, so that the base sleeved on the shaft can also rotate eccentrically around the first axis. A diaphragm is disposed on the base and connected to the base. The diaphragm is made of an elastic material and can deform when pushed or pulled to change the volume of the cavity in the booster pump. For example, when the diaphragm is stretched outward, the volume of the cavity increases; conversely, when the diaphragm returns to its original shape or is pushed inward, the volume of the cavity decreases, thereby realizing the extraction and pumping of liquid through pushing and pulling.

[0053] A fourth aspect of the present invention provides a water purifier, which includes a booster pump as described in any of the above technical solutions.

[0054] This technical solution defines a water purifier equipped with a booster pump as described in any of the above technical solutions. Therefore, the water purifier has the advantages of the booster pump in any of the above technical solutions and can achieve the technical effects achieved by the booster pump in any of the above technical solutions. To avoid repetition, it will not be described in detail here.

Detailed Implementation

[0071] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0073] The following reference Figures 1 to 12 The present invention describes a support mechanism, a valve core assembly, a booster pump, and a water purifier according to some embodiments thereof.

[0074] Example 1

[0075] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a first aspect embodiment of the present invention provides a support mechanism 100, which includes: a base 110 including a guide groove 112; a heat-insulating member 120 disposed on the base 110, the heat-insulating member 120 being partially embedded in the guide groove 112, the heat-insulating member 120 being used to support a diaphragm 210, and the heat-insulating member 120 being used to drive the diaphragm 210 to move; wherein, in the depth direction of the guide groove 112, the cross-sectional area of ​​the guide groove 112 gradually decreases.

[0076] This application defines a support mechanism 100 for a booster pump 300. The support mechanism 100 includes a base 110, which is used to connect a diaphragm 210 on the booster pump 300 and drive the diaphragm 210 to move within the booster pump 300. The diaphragm 210 is a core component of the booster pump 300. The base 110 connects the diaphragm 210 and a drive assembly 320. The drive assembly 320 drives the diaphragm 210 to swing within the booster pump 300 by driving a bearing 326 on the base 110 to swing. The swinging diaphragm 210 can change the size of the pumping chamber on the opposite side of the base 110. When the swinging diaphragm 210 increases the size of the pumping chamber, negative pressure forces liquid into the pumping chamber. Conversely, when the swinging diaphragm 210 decreases the size of the pumping chamber, previously pumped liquid is forced out of the pumping chamber, thereby meeting the liquid pumping requirements.

[0077] In related technologies, due to product demands, the required pumping flow rate of booster pumps is increasing, with the flow rates of booster pumps on the market developing from 600G, 800G to 1200G, representing a significant increase. One way to increase pumping flow rate is to accelerate the diaphragm's movement frequency, but this high-speed efficiency enhancement method generates a large amount of heat during operation, causing the base and the diaphragm in contact with the base to heat up, with actual temperatures reaching around 70℃. However, diaphragms are mostly made of elastic materials such as rubber, and high temperatures have an irreversible impact on their performance, leading to rapid diaphragm aging. This results in technical problems such as short diaphragm lifespan, high failure rate, and poor booster pump reliability.

[0078] To address this, this application incorporates a heat-insulating component 120 within the support mechanism 100. Specifically, the heat-insulating component 120 is fixed to the base 110 and supports the diaphragm 210. After assembly, the heat-insulating component 120 is positioned between the base 110 and the diaphragm 210, maintaining contact with the diaphragm 210. As the heat-insulating component 120 moves with the base 110, the diaphragm 210 in contact with it deforms. The heat-insulating component 120 possesses excellent thermal insulation properties, effectively reducing heat transfer efficiency between the base 110 and the diaphragm 210. Specifically, the heat-insulating component 120 can be made of PA6+30GF (Nylon 66+30% glass fiber) material, or it can be made of thermal insulation materials such as ceramics. In this embodiment, the material of the heat-insulating component 120 is not strictly limited, as long as it meets the thermal insulation requirements.

[0079] By providing a heat-insulating component 120 between the base 110 and the diaphragm 210, the heat transfer efficiency from the base 110 to the diaphragm 210 can be effectively reduced, thereby lowering the temperature of the diaphragm 210 during operation and preventing high-temperature damage. This solves the technical problems existing in the aforementioned related technologies. Furthermore, it optimizes the structure of the valve core assembly 200, extending the service life of the diaphragm 210 while meeting high-flow pumping requirements, reducing the failure rate of the support mechanism 100, and reducing the failure rate of the booster pump 300.

[0080] Specifically, in this embodiment, the base 110 and the heat-insulating component 120 are separate structures. By setting the base 110 and the heat-insulating component 120 separately, on the one hand, the base 110 can be made of a metal material with higher strength, so as to ensure that the base 110 can drive the diaphragm 210 to move at high speed for a long time and reduce the failure rate of the base 110. On the other hand, the heat insulation performance of the heat-insulating component 120 can be adjusted by selecting and replacing heat-insulating components 120 of different materials, so as to select the corresponding material of the heat-insulating component 120 according to the pumping flow requirements of the booster pump 300, thereby reducing the cost of the support mechanism 100 while meeting the heat insulation requirements.

[0081] Based on this, a guide groove 112 is provided on the base 110. The shape of the guide groove 112 is adapted to the outer contour shape of part of the heat-insulating component 120. By embedding part of the heat-insulating component 120 into the guide groove 112, the positioning and assembly of the heat-insulating component 120 on the base 110 can be completed, ensuring the positioning accuracy of the heat-insulating component 120 on the base 110 and ensuring that the base 110 and the heat-insulating component 120 can drive the diaphragm 210 to swing precisely. Specifically, by cutting the guide groove 112 with a plane perpendicular to the depth direction of the guide groove 112, the cross-sectional area of ​​the guide groove 112 can be determined. Furthermore, the cross-sectional area of ​​the guide groove 112 gradually decreases along the depth direction of the guide groove 112, thus forming a guide groove 112 that gradually shrinks from top to bottom. By limiting the guide groove 112 to taper along its depth direction, a funnel-shaped guide groove 112 can be formed. This funnel shape serves as a guide, allowing some of the heat-insulating components 120 to slide to their predetermined installation positions after being placed in the guide groove 112, thereby reducing the probability of misinstallation of the heat-insulating components 120. This further optimizes the positioning structure of the heat-insulating components 120, improves their positioning accuracy, and increases the yield rate of the support mechanism 100%.

[0082] Example 2

[0083] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in a second aspect embodiment of the present invention, the base 110 further includes a blind hole, and the support mechanism 100 further includes a guide member 114 disposed in the blind hole, including a guide slope opposite to the sidewall of the blind hole; the guide slope and the blind hole enclose a guide groove 112.

[0084] In this embodiment, the structure of the base 110 is further defined. Specifically, a blind hole is provided on the surface of the base 110 facing the heat-insulating member 120, and a guide member 114 is provided in the blind hole. A guide slope is formed on the periphery of the guide member 114. The guide slope, the bottom wall of the blind hole, and the side wall of the blind hole together form a guide groove 112. The guide slope is inclined relative to the side wall of the blind hole, thereby forming a tapered guide groove 112. After the heat-insulating member 120 is assembled, part of the heat-insulating member 120 is embedded in and fills the guide groove 112 to accurately position the heat-insulating member 120 and prevent the heat-insulating member 120 from shaking relative to the base 110 during operation. This improves the control accuracy of the diaphragm 210 and precisely controls the liquid pumping efficiency.

[0085] In any of the above embodiments, the guide 114 is a frustum, and the bottom surface of the frustum is connected to the bottom wall of the blind hole.

[0086] In this embodiment, following the previous embodiment, the shape of the guide 114 is defined. Specifically, the guide 114 is a frustum, the bottom surface of which is connected to the bottom wall of the blind hole, and the top surface faces the heat-insulating member 120. The multiple sides of the frustum are the guide ramps.

[0087] In this embodiment, the cross-sectional shapes of the guide groove 112 and the guide member 114 are both regular polygons. For example, the cross-sectional shape of the guide groove 112 is an equilateral triangle, and the guide member 114 is a corresponding triangular frustum; the cross-sectional shape of the guide groove 112 is a regular quadrilateral, and the guide member 114 is a corresponding quadrangular frustum; or the cross-sectional shape of the guide groove 112 is a regular octagon, and the guide member 114 is a corresponding octagonal frustum. During operation, the peripheral surface of the frustum abuts against the side wall of the guide groove 112 to prevent the heat-insulating member 120 from rotating relative to the positioning part. Therefore, this embodiment does not impose rigid limitations on the shapes of the guide groove 112 and the guide member 114, as long as the aforementioned positioning requirements are met.

[0088] In any of the above embodiments, the guide 114 is a hexagonal frustum.

[0089] In this embodiment, the guide groove 112 has a regular hexagonal cross-section, and the guide member 114 has a hexagonal truncated pyramid cross-section. By inserting a portion of the heat-insulating member 120 between the hexagonal truncated pyramid and the guide groove 112, the heat-insulating member 120 can be snapped onto the positioning part. The hexagonal truncated pyramid has a through hole for the connector 126 to connect the heat-insulating member 120 and the base 110.

[0090] Specifically, the heat-insulating component 120 and the guide groove 112 are interference-fitted. By limiting this interference fit, a tight connection between the base 110 and the heat-insulating component 120 can be achieved, thereby improving the positioning accuracy of the heat-insulating component 120 and preventing the heat-insulating component 120 from misaligning relative to the positioning part or even coming off the positioning part during operation. This, in turn, achieves the technical effect of improving the structural stability and reliability of the support mechanism 100.

[0091] In any of the above embodiments, there are N guide grooves 112, which are evenly distributed on the base 110; where N is an integer greater than 2.

[0092] In this embodiment, the base 110 is provided with N positioning parts, each positioning part having a guide groove 112. Based on this, the distribution of the guide grooves 112 on the base 110 is defined. Specifically, the base 110 has a ring-shaped structure. On the base 110, at least three guide grooves 112 are evenly distributed on the same circle with the axis of the base 110 as the axis, forming a ring-shaped array of guide grooves 112 on the body 122. By evenly distributing multiple guide grooves 112 along the ring line on the body 122, the uniformity of the force distribution on the base 110 can be improved, preventing damage to the diaphragm 210 due to uneven force. This achieves the technical effect of optimizing the structure of the base 110 and extending the service life of the diaphragm 210.

[0093] In any of the above embodiments, the base 110 is annular, and N guide grooves 112 are evenly distributed on the same circle with the axis of the base 110 as the axis.

[0094] In this embodiment, the distribution of the guide grooves 112 on the base 110 is defined. Specifically, the base 110 has a ring-shaped structure. At least three guide grooves 112 are evenly distributed on the same circle about the axis of the base 110, forming a ring-shaped array of guide grooves 112 on the body 122. By evenly distributing multiple guide grooves 112 along the ring line on the body 122, the uniformity of the force distribution on the base 110 can be improved, preventing damage to the diaphragm 210 due to uneven force. This achieves the technical effect of optimizing the structure of the base 110 and extending the service life of the diaphragm 210.

[0095] like Figure 1 and Figure 2 As shown, in any of the above embodiments, there are N heat-insulating elements 120, and the N heat-insulating elements 120 are connected to the N guide grooves 112 in a one-to-one correspondence.

[0096] In this embodiment, the number of heat-resistant elements 120 and the correspondence between the heat-resistant elements 120 and the guide grooves 112 are limited. Specifically, the number of heat-resistant elements 120 is the same as the number of guide grooves 112, and N guide grooves 112 are arranged one-to-one with N heat-resistant elements 120 to form a ring-shaped array of N heat-resistant elements 120 on the base 110, so that the diaphragm 210 is supported by the N heat-resistant elements 120. By setting N heat-resistant elements 120 corresponding to N guide grooves 112, the contact area between the heat-resistant elements 120 and the diaphragm 210 can be reduced while meeting the positioning and connection requirements of the diaphragm 210, so as to avoid large-area contact affecting the movement range of the diaphragm 210. This achieves the technical effect of optimizing the structure of the support mechanism 100 and improving the pumping performance of the support mechanism 100.

[0097] Example 3

[0098] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in a third aspect embodiment of the present invention, the heat-insulating member 120 includes: a body 122; and a rib 124 disposed on the body 122, the rib 124 being embedded in the guide groove 112.

[0099] In this embodiment, the structure of the heat-insulating component 120 is defined. Specifically, the heat-insulating component 120 includes a body 122 and a rib 124. The body 122 is located outside the guide groove 112 and is used to support and connect the diaphragm 210. The top surface of the body 122 is in contact with the diaphragm 210. When the driving base 110 swings, the body 122 pushes and pulls the diaphragm 210 to deform the diaphragm 210. This deformation of the diaphragm 210 changes the size of the cavity on the side away from the base 110, thereby completing the extraction and pumping of liquid. The rib 124 is provided on the bottom surface of the body 122. The shape of the rib 124 is adapted to the shape of the guide groove 112. During assembly, the rib 124 is first aligned with the guide groove 112, and then the rib 124 is accurately pushed into the guide groove 112 through the guide ramp to accurately position the heat-insulating component 120 on the base 110.

[0100] The positioning part has a columnar structure, and the heat-insulating component 120 is provided with a mounting groove whose shape matches the outer contour of the positioning part. During assembly, the positioning part is first aligned with the mounting groove, and then the positioning part is inserted into the mounting groove to complete the assembly of the heat-insulating component 120. By setting the mounting groove, a nested positioning connection structure can be formed with the positioning part and the guide groove 112, thereby improving the positioning accuracy of the heat-insulating component 120. At the same time, this nested connection structure can improve the positioning stability of the heat-insulating component 120, preventing the heat-insulating component 120 from misaligning or even falling off during long-term reciprocating motion. This achieves the technical effect of improving the structural stability of the support mechanism 100 and reducing the failure rate of the support mechanism 100.

[0101] In any of the above embodiments, the rib 124 and the guide groove 112 are interference-fitted.

[0102] In this embodiment, following the previous embodiment, the protruding rib 124 and the guide groove 112 are interference-fitted. Specifically, the side of the protruding rib 124 facing the base 110 is the front end of the protruding rib 124, and the opposite side is the end of the protruding rib 124. During assembly, after the protruding rib 124 is aligned with the guide groove 112, the front end of the protruding rib 124 is placed on the guide ramp. Under the action of the guide ramp, the protruding rib 124 slides towards the bottom of the guide groove 112, thereby completing the pre-assembly of the heat-insulating component 120. However, at this time, because the size of the protruding rib 124 is slightly larger than the size of the guide groove 112, the protruding rib 124 is not completely submerged in the guide groove 112. Subsequently, the protruding rib 124 is pressed into the guide groove 112 by the connector 126 so that the outer surface of the protruding rib 124 is tightly fitted with the inner wall surface of the guide groove 112, thereby eliminating the gap between the protruding rib 124 and the guide groove 112 and preventing the heat-insulating component 120 from being misaligned or even falling off during operation. This achieves the technical effect of optimizing the positioning structure of the heat-insulating component 120, improving the positioning accuracy of the heat-insulating component 120, and reducing the failure rate of the support mechanism 100.

[0103] Example 4

[0104] like Figure 1 , Figure 2 and Figure 11 As shown, in a fourth aspect embodiment of the present invention, the heat-insulating member 120 is detachably connected to the base 110.

[0105] In this embodiment, the heat-insulating component 120 and the base 110 are detachably connected. By providing this detachable structure, on the one hand, modular design of the base 110 and the heat-insulating component 120 can be achieved, allowing for the provision of heat-insulating components 120 with corresponding insulation performance for bases 110 with different pumping efficiencies. On the other hand, by providing detachable heat-insulating components 120, maintenance of the support mechanism 100 can be quickly completed by disassembling and replacing a heat-insulating component 120 when it ages or is damaged, thus providing convenience for users and reducing product maintenance difficulty and costs.

[0106] In any of the above embodiments, the support mechanism 100 further includes: a connector 126, a connecting base 110, and a heat-insulating member 120.

[0107] In this embodiment, the valve core assembly 200 is also provided with a connector 126. After the initial positioning of the heat-insulating element 120 is completed by the guide groove 112, the heat-insulating element 120 and the base 110 are connected by the connector 126 so that the base 110 can drive the heat-insulating element 120 and the diaphragm 210 to swing together, thereby preventing the heat-insulating element 120 and the base 110 from separating.

[0108] Specifically, the connector 126 can be a screw. When a screw is selected for the connector 126, the heat-insulating component 120 is provided with a first screw hole, and the rib 124 is arranged around the first screw hole. The base 110 is provided with a corresponding second screw hole, which is located on the guide component 114. The screw passes through the first screw hole and is inserted into the second screw hole to connect the heat-insulating component 120 and the base 110. This structure is only one optional structure for the connector 126. Other connection structures such as snap-fit ​​slots can also be used to complete the connection between the heat-insulating component 120 and the base 110. This application does not impose rigid limitations on the structure of the connector 126, as long as the requirement of reliable connection is met.

[0109] Example 5

[0110] like Figure 11 As shown, a fifth aspect embodiment of the present invention provides a valve core assembly 200, the valve core assembly 200 including: a support mechanism 100 as in any of the above embodiments; a diaphragm 210 disposed on a heat-insulating member 120, the heat-insulating member 120 being located between a base 110 and the diaphragm 210.

[0111] In this embodiment, a valve core assembly 200 is defined that is provided with the support mechanism 100 in any of the above embodiments. Therefore, the valve core assembly 200 has the advantages of the support mechanism 100 in any of the above embodiments and can achieve the technical effects achieved by the support mechanism 100 in any of the above embodiments.

[0112] In related technologies, due to product demands, the pumping flow rate of booster pumps 300 is increasingly required, and the flow rates of booster pumps 300 on the market are developing towards high-flow rates of 600G, 800G, and even 1200G. However, one way to increase the pumping flow rate is to increase the movement frequency of the diaphragm 210. But this high-speed efficiency enhancement method generates a large amount of heat during operation, causing the base 110 and the diaphragm 210 connected to the base 110 to heat up, with actual temperatures reaching around 70℃. However, the diaphragm 210 is mostly made of elastic materials such as rubber, and high temperatures have an irreversible impact on the performance of the diaphragm 210, leading to rapid aging. This results in technical problems such as short service life of the diaphragm 210, high failure rate, and poor reliability of the booster pump 300.

[0113] To address this, this application incorporates a heat-insulating component 120 within the support mechanism 100. Specifically, the heat-insulating component 120 is fixed to the base 110 and supports the diaphragm 210. After assembly, the heat-insulating component 120 is positioned between the base 110 and the diaphragm 210, maintaining contact with the diaphragm 210. As the heat-insulating component 120 moves with the base 110, the diaphragm 210 in contact with it deforms. The heat-insulating component 120 possesses excellent thermal insulation properties, effectively reducing heat transfer efficiency between the base 110 and the diaphragm 210. Specifically, the heat-insulating component 120 can be made of PA6+30GF (Nylon 66+30% glass fiber) material, or it can be made of thermal insulation materials such as ceramics. In this embodiment, the material of the heat-insulating component 120 is not strictly limited, as long as it meets the thermal insulation requirements.

[0114] By providing a heat-insulating element 120 between the base 110 and the diaphragm 210, the heat transfer efficiency from the base 110 to the diaphragm 210 can be effectively reduced, thereby lowering the temperature of the diaphragm 210 during operation and preventing high-temperature damage. This solves the technical problems existing in the aforementioned related technologies. Furthermore, it optimizes the structure of the valve core assembly 200, extending the service life of the diaphragm 210 while meeting high-flow pumping requirements, reducing the failure rate of the valve core assembly 200, and lowering the failure rate of the booster pump 300.

[0115] Specifically, in this embodiment, the base 110 and the heat-insulating component 120 are separate structures. By setting the base 110 and the heat-insulating component 120 separately, on the one hand, the base 110 can be made of a metal material with higher strength, so as to ensure that the base 110 can drive the diaphragm 210 to move at high speed for a long time and reduce the failure rate of the base 110. On the other hand, the heat insulation performance of the heat-insulating component 120 can be adjusted by selecting and replacing heat-insulating components 120 of different materials, so as to select the corresponding material of the heat-insulating component 120 according to the pumping flow requirements of the booster pump 300, thereby reducing the cost of the valve core assembly 200 while meeting the heat insulation requirements.

[0116] In any of the above embodiments, the valve core assembly 200 further includes: a pressing member 220 disposed on the diaphragm 210 and facing away from the heat-insulating member 120, the pressing member 220 being connected to the heat-insulating member 120 for pressing the diaphragm 210 onto the heat-insulating member 120.

[0117] In this embodiment, the valve core assembly 200 also includes a clamping member 220, which is disposed on the diaphragm 210. A connecting member 126 passes through the diaphragm 210 and connects the clamping member 220 and the heat-insulating member 120, so that the clamping member 220 presses the diaphragm 210 tightly against the heat-insulating member 120, ensuring a close fit between the diaphragm 210 and the top surface of the heat-insulating member 120, thereby achieving the clamping of the diaphragm 210. The diaphragm 210 is the main working part of the booster pump 300. During operation, the booster pump 300 drives the diaphragm 210 to move, changing the size of the space separated by the diaphragm 210, thereby completing the extraction, pressurization, and discharge of the medium. The connecting member 126 and the clamping member 220 accurately position the diaphragm 210 within the booster pump 300, reducing the possibility of misalignment during operation. Furthermore, the clamping member 220 can make the diaphragm 210 fit tightly against the base 110, thereby eliminating the gap between the first positioning surface and the diaphragm 210, thus improving the motion accuracy of the diaphragm 210 and ensuring the pumping efficiency of the valve core assembly 200.

[0118] Example 6

[0119] like Figure 12 As shown, a sixth aspect embodiment of the present invention provides a booster pump 300, which includes: a housing 310 including a cavity; a valve core assembly 200 as in any of the above embodiments, disposed in the cavity; a diaphragm 210 connected to the housing 310 and the diaphragm 210 separating the cavity.

[0120] In this embodiment, a booster pump 300 is defined that is provided with the valve core assembly 200 in any of the above embodiments. Therefore, the booster pump 300 has the advantages of the valve core assembly 200 in any of the above embodiments and can achieve the technical effects achieved by the valve core assembly 200 in any of the above embodiments. To avoid repetition, it will not be described again here.

[0121] Specifically, the booster pump 300 includes a housing 310, which serves as the external frame structure of the booster pump 300, used to enclose and define a cavity. A base 110 and a clamping member 220 are disposed within the cavity, thereby positioning a diaphragm 210 within the housing 310. The periphery of the diaphragm 210 is connected to the inner wall of the housing 310 to divide the cavity into two sub-cavities, with the base 110 and clamping member 220 located in the sub-cavities on either side of the diaphragm 210. When the base 110 moves a portion of the diaphragm 210 and the clamping member 220 relative to the housing 310, the diaphragm 210 connected to the housing 310 is pushed and pulled, causing deformation. During the stretching process, the volume of the sub-cavity where the clamping member 220 is located increases, allowing the booster pump 300 to draw media into this sub-cavity. When the diaphragm 210 is pushed by the base 110 toward the clamping member 220, the volume of the sub-cavity where the clamping member 220 is located decreases, so that the medium in the sub-cavity is pushed out of the booster pump 300. Thus, the booster pump 300 pumps the medium.

[0122] In any of the above embodiments, the housing 310 further includes an inlet and an outlet, which are connected to the cavity of the diaphragm 210 on the side opposite to the base 110. The booster pump 300 further includes a drive assembly 320 connected to the base 110 for driving the base 110 to swing relative to the housing 310.

[0123] In this embodiment, the housing 310 is provided with an inlet and an outlet for the medium to enter and exit. Both the inlet and outlet are connected to a sub-cavity on one side of the diaphragm 210. The base 110 and the drive component 322 are disposed in the sub-cavity on the side opposite to the inlet and outlet. Specifically, the drive component 320 is fixed to the housing 310, and the base 110 connects the drive component 320 and the diaphragm 210. When the booster pump 300 is working, the drive component 320 drives the base 110 and the clamping component 220 to move relative to the housing 310, so as to realize the intake and discharge of the medium by pushing and pulling the diaphragm 210.

[0124] In any of the above embodiments, the drive assembly 320 includes: a drive member 322, including a drive shaft; an eccentric wheel 324, sleeved on the drive shaft; and a bearing 326, the inner ring of which is sleeved on the eccentric wheel 324, and the outer ring of which passes through the base 110.

[0125] In this embodiment, the structure of the drive assembly 320 is defined. Specifically, the drive assembly 320 includes a drive member 322, an eccentric wheel 324, and a bearing 326. The eccentric wheel 324 and the bearing 326 form the transmission structure between the base 110 and the drive member 322. The bearing 326 is sleeved on the shaft of the eccentric wheel 324, and the base 110 is sleeved on the outside of the bearing 326. During operation, the eccentric wheel 324 rotates around a first axis, and there is a first angle between the axis of the shaft and the first axis, so that the base 110 sleeved on the shaft can also rotate eccentrically around the first axis. A diaphragm 210 is disposed on the base 110 and connected to the base 110. The diaphragm 210 is made of an elastic material and can deform when pushed or pulled to change the volume of the cavity in the booster pump 300. For example, when the diaphragm 210 is stretched outward, the volume of the cavity increases; conversely, when the diaphragm 210 returns to its original shape or is pushed inward, the volume of the cavity decreases. Thus, the extraction and pumping of liquid are achieved by pushing and pulling.

[0126] A fourth aspect of the present invention provides a water purifier, which includes a booster pump 300 as described in any of the above embodiments.

[0127] In this embodiment, a water purifier is defined that is equipped with the booster pump 300 of any of the above embodiments. Therefore, the water purifier has the advantages of the booster pump 300 of any of the above embodiments and can achieve the technical effects achieved by the booster pump 300 of any of the above embodiments. To avoid repetition, it will not be described again here.
