Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purification, and in particular to a hinge structure and a water purifier containing the same. Background Technology
[0002] With the increasing severity of water pollution, people are paying more and more attention to the safety and health of drinking water. Traditional tap water supply methods can no longer fully meet people's demand for high-quality drinking water. Water purifiers can effectively remove impurities, bacteria, viruses, heavy metals and odors from water, providing people with safe and healthy drinking water and satisfying people's pursuit of drinking water quality.
[0003] The salt-adding device of a water purifier consists of a salt-adding body and a fixing component. The salt inlet is opened and closed via a rotating connection, allowing the operator to add salt. However, most current devices use a one-piece molded hinge to achieve this connection. While this design ensures structural stability to some extent, frequent opening and closing of the salt-adding body can cause deformation in certain parts of the hinge, affecting its lifespan and reliability. Furthermore, due to the limitations of the one-piece structure, if the hinge malfunctions, the operator cannot disassemble and repair a specific part; the entire hinge must be replaced, increasing operating costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defect of existing one-piece molded hinges, which cannot be disassembled and repaired separately after a certain part is deformed, and can only be replaced. This utility model provides a hinge structure and a water purifier containing the hinge.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] This utility model discloses a hinge structure for a water purifier. The water purifier includes a salt-adding body and a fixing member. The salt-adding body is used to open or close relative to the fixing member. The hinge structure includes a first bracket, a second bracket, and a rotating shaft. The first bracket is used to connect with the salt-adding body, and the second bracket is used to connect with the fixing member. The first bracket has a first rotating hole, and the second bracket has a second rotating hole. The first rotating hole and the second rotating hole pass through the first bracket and the second bracket respectively along the axial direction of the rotating shaft, so that the second bracket rotates relative to the first bracket along the axial direction of the rotating shaft. The rotation direction of the second bracket relative to the first bracket is parallel to the direction in which the salt-adding body opens or closes relative to the fixing member.
[0007] The hinge structure further includes a protrusion, which is connected to the surface of the first bracket facing the second bracket and protrudes from the surface of the first bracket facing the second bracket toward the direction closer to the second bracket. The first rotating hole is provided on the protrusion. The cross-sectional area of the protrusion gradually decreases from the side closer to the first bracket to the side farther away from the first bracket.
[0008] In this design, the aforementioned structural form connects the first and second supports via a rotating shaft. The direction of rotation is parallel to the opening and closing direction of the salt-adding body relative to the fixed component, ensuring smooth and stable operation of the salt-adding body during opening and closing. This effectively reduces inconvenience and potential damage risks caused by shaking or misalignment. Furthermore, the first and second supports are detachably connected via the rotating shaft. Therefore, if either the first or second support is damaged, only the damaged support needs to be replaced for normal operation, reducing operating costs.
[0009] Preferably, the first support includes a first part and a second part, the first part being connected to the protrusion, and the second part being connected to the end of the first part away from the protrusion and extending from the first part toward the salting body.
[0010] The first part and / or the second part have a first connecting hole, and the first connector extends through the first connecting hole and into the salting body to connect with the salting body.
[0011] In this solution, the above-mentioned structural form is adopted, and the connection between the first support and the salt-adding body is realized through the first part and / or the second part.
[0012] Preferably, a groove is provided on the side of the first portion and / or the second portion of the first connecting hole away from the salting body, the groove being connected to the first connecting hole and used to accommodate the first connector.
[0013] In this design, the aforementioned structural form, with its recessed groove, prevents the first connector from protruding from the first bracket, thus avoiding injury to operators caused by its protrusion. Furthermore, housing the first connector within the groove improves the flatness of the hinge structure, reduces interference to other components caused by the exposed first connector, and enhances the stability and reliability of the hinge structure.
[0014] Preferably, the first part and the second part are integrally formed.
[0015] In this solution, the above-mentioned structural form is adopted, which improves the structural strength of the first support.
[0016] Preferably, the hinge structure further includes a boss connected to the protrusion, the first rotating hole passing through the boss along the axial direction of the rotating shaft, and the end of the boss away from the first bracket for abutting against the second bracket.
[0017] In this design, the aforementioned structural form is adopted, and the first and second supports are rotatably connected via a boss and a second support. Furthermore, the boss abuts against the second support, thus providing support for the second support and improving the stability of the second support's rotation relative to the first support.
[0018] Preferably, the hinge structure further includes a fixing member, one end of the rotating shaft abuts against the first bracket or the second bracket, and the other end of the rotating shaft passes through the first bracket and the second bracket and is connected to the fixing member. The fixing member is used to restrict the movement of the rotating shaft along the axial direction of the rotating shaft.
[0019] In this solution, the above-mentioned structural form is adopted, and the fixing component can prevent the first bracket and the second bracket from detaching from the rotation axis, thereby improving the stability and reliability of the rotation of the second bracket relative to the first bracket.
[0020] Preferably, the hinge structure further includes a washer, the washer being sleeved on the rotating shaft, and one end of the washer abutting against one of the first bracket and the second bracket near the fixing member, and the other end of the washer abutting against the fixing member; wherein the washer is made of rubber.
[0021] In this design, the aforementioned structural form prevents direct contact between the fixing component and the first or second bracket, thus preventing friction and improving the durability and service life of the hinge structure. Furthermore, the rubber material of the gasket provides excellent elasticity, offering cushioning and shock absorption between the fixing component and the first or second bracket, reducing dynamic impact forces caused by frequent opening and closing operations, improving the stability of the hinge structure's opening and closing, and reducing noise during hinge operation.
[0022] Preferably, a second connecting hole is provided on the second bracket, and the second connector extends through the second connecting hole and into the fixing member to connect with the fixing member.
[0023] In this solution, the above-mentioned structural form is used to achieve the connection between the second bracket and the fixing component.
[0024] Preferably, the first support and / or the second support are sheet-like;
[0025] And / or, the first bracket and the second bracket are made of stainless steel.
[0026] This utility model discloses a water purifier, which includes the hinge structure as described in any of the preceding claims.
[0027] In this design, a hinge structure is applied to the water purifier. Using this structure, the first and second supports are connected by a rotating shaft, with the rotation direction parallel to the opening and closing direction of the salt-adding body relative to the fixed component. This ensures smooth and stable operation of the salt-adding body during opening and closing, effectively reducing inconvenience and potential damage risks caused by shaking or misalignment. Furthermore, the first and second supports are detachably connected via the rotating shaft. Therefore, if either the first or second support is damaged, only the damaged support needs to be replaced for normal operation, reducing operating costs.
[0028] The positive and progressive effects of this utility model are as follows:
[0029] The first and second supports are connected by a rotating shaft, and the direction of rotation is parallel to the opening and closing direction of the salt-adding body relative to the fixed part. This ensures that the salt-adding body operates smoothly and steadily during opening and closing, effectively reducing inconvenience and potential damage risks caused by shaking or misalignment. Furthermore, the first and second supports are detachably connected via the rotating shaft. Therefore, if either the first or second support is damaged, only the damaged support needs to be replaced for normal operation, reducing operating costs. Attached Figure Description

[0058] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0059] like Figures 1 to 5As shown, this embodiment provides a hinge structure 100 for a water purifier 1000. The water purifier 1000 includes a salt-adding body 200 and a fixing member 300. The salt-adding body 200 is used to open or close relative to the fixing member 300. The hinge structure 100 includes a first bracket 1, a second bracket 2, and a rotating shaft 3. The first bracket 1 is used to connect with the salt-adding body 200, and the second bracket 2 is used to connect with the fixing member 300. A first rotating hole 11 is provided on the first bracket 1, and a second rotating hole 21 is provided on the second bracket 2. The first rotating hole 11 and the second rotating hole 21 respectively penetrate along the axial direction of the rotating shaft 3. A first bracket 1 and a second bracket 2 are used to allow the second bracket 2 to rotate relative to the first bracket 1 along the axis of the rotation shaft 3. The rotation direction of the second bracket 2 relative to the first bracket 1 is parallel to the opening or closing direction of the salt-adding body 200 relative to the fixing member 300. The hinge structure 100 also includes a protrusion 4, which is connected to the surface of the first bracket 1 facing the second bracket 2 and protrudes from the surface of the first bracket 1 facing the second bracket 2 towards the second bracket 2. A first rotation hole 11 is provided on the protrusion 4. The cross-sectional area of the protrusion 4 gradually decreases from the side closer to the first bracket 1 to the side farther away from the first bracket 1. With the above structure, the first bracket 1 and the second bracket 2 are connected by the rotation shaft 3, and the rotation direction is parallel to the opening and closing direction of the salt-adding body 200 relative to the fixing member 300. This ensures that the salt-adding body 200 moves smoothly and steadily during opening and closing, effectively reducing inconvenience and potential damage risks caused by shaking or displacement. In addition, the first bracket 1 and the second bracket 2 are detachably connected by a rotating shaft 3, so that if one of the first bracket 1 and the second bracket 2 is damaged, only the damaged first bracket 1 or the second bracket 2 needs to be replaced to restore normal use, thus reducing the cost of use.
[0060] In practical use, both ends of the first support 1 are rounded to prevent cuts to operators. The protrusion 4 has a trapezoidal structure, and the side with the larger cross-sectional area of the trapezoid is rounded, thereby increasing the structural strength of the first support 1. Preferably, the protrusion 4 and the first support 1 are integrally formed, which further helps to improve the structural strength of the hinge structure 100.
[0061] In this embodiment, the rotating shaft 3 is a bolt. In other embodiments, the rotating shaft 3 may take other forms, which are not limited here. In addition, the second bracket 2 is shaped like a "7". In other embodiments, the shape of the second bracket 2 can be adjusted according to actual needs, which are not limited here.
[0062] like Figure 1 , Figure 2 as well as Figure 5As shown, the first support 1 includes a first part 12 and a second part 13. The first part 12 is connected to the protrusion 4, and the second part 13 is connected to the end of the first part 12 away from the protrusion 4 and extends from the first part 12 toward the salting body 200. To achieve the connection between the first support 1 and the salting body 200, the first support 1 can have the following implementations: In the first implementation, a first connecting hole 14 is provided on the first part 12; in the second implementation, a first connecting hole 14 is provided on the second part 13; in the third implementation, both the first part 12 and the second part 13 have first connecting holes 14. In all three implementations, the first connecting hole 14 allows the first connector 8 to pass through, so that the first connector 8 extends into the salting body 200 and connects with it.
[0063] Preferably, in this embodiment, both the first part 12 and the second part 13 have first connection holes 14, thereby improving the stability and reliability of the connection between the first support 1 and the salt-adding body 200.
[0064] In practical use, the first support 1 can be positioned at a corner of the salt-adding body 200. Specifically, the first part 12 is connected to the first surface of the salt-adding body 200, and the second part 13 is connected to the second surface of the salt-adding body 200. The angle between the extending directions of the first and second surfaces is consistent with the angle at which the second part 13 bends from the first part 12 toward the second surface, thereby increasing the connection area between the first support 1 and the salt-adding body 200, and thus improving the stability and reliability of the connection between the first support 1 and the salt-adding body 200.
[0065] like Figure 5 As shown, a groove 15 is formed on the side of the first part 12 and the second part 13 away from the salt-adding body 200 where the first connecting hole 14 is opened. The groove 15 is connected to the first connecting hole 14 and is used to accommodate the first connecting member 8. By adopting the above-described structure and providing the groove 15, the first connecting member 8 can be prevented from protruding from the first bracket 1, thereby avoiding the first connecting member 8 from scratching the operator due to protrusion. In addition, accommodating the first connecting member 8 in the groove 15 is beneficial to the flatness of the hinge structure 100, reduces the interference of the exposed first connecting member 8 to other components, and improves the stability and reliability of the hinge structure 100.
[0066] Preferably, in this embodiment, the first part 12 and the second part 13 are integrally formed, thereby improving the structural strength of the first support 1. In other embodiments, the first part 12 and the second part 13 can also be separately configured and connected together, so that if one of the first part 12 and the second part 13 is damaged, only the damaged first part 12 or the second part 13 needs to be replaced to restore normal use, thus reducing the cost of use.
[0067] like Figure 1 , Figure 2 as well as Figure 5 As shown, the hinge structure 100 also includes a boss 5, which is connected to the protrusion 4. A first rotating hole 11 passes through the boss 5 along the axial direction of the rotating shaft 3. The end of the boss 5 away from the first support 1 is used to abut against the second support 2. Using the above structure, the first support 1 and the second support 2 are rotatably connected through the boss 5 and the second support 2. Furthermore, the abutment between the boss 5 and the second support 2 provides support for the second support 2, improving the stability of the second support 2's rotation relative to the first support 1.
[0068] In this embodiment, the boss 5 is cylindrical. In other embodiments, the shape of the boss 5 can be adjusted according to actual needs, and is not limited here.
[0069] like Figures 1 to 3 As shown, the hinge structure 100 also includes a fixing member 300. One end of the rotating shaft 3 abuts against the first bracket 1 or the second bracket 2, and the other end of the rotating shaft 3 passes through the first bracket 1 and the second bracket 2 and is connected to the fixing member 300. The fixing member 300 is used to restrict the movement of the rotating shaft 3 along the axial direction of the rotating shaft 3. With the above structural form, the fixing member 300 can prevent the first bracket 1 and the second bracket 2 from disengaging from the rotating shaft 3, thereby improving the stability and reliability of the rotation of the second bracket 2 relative to the first bracket 1.
[0070] In this embodiment, the fixing member 300 is a nut, and the nut is threadedly connected to the rotating shaft 3. In other embodiments, the fixing member 300 may take other forms, which are not limited here.
[0071] like Figure 2 and Figure 3 As shown, the hinge structure 100 also includes a washer 7, which is sleeved on the rotating shaft 3. One end of the washer 7 abuts against one of the first bracket 1 and the second bracket 2 near the fixing member 300, and the other end of the washer 7 abuts against the fixing member 300. The washer 7 is made of rubber. With this structure, the washer 7 prevents direct contact between the fixing member 300 and the first bracket 1 or the second bracket 2, thereby preventing friction between them and improving the durability and service life of the hinge structure 100. Furthermore, the rubber material of the washer 7 provides good elasticity, offering cushioning and shock absorption between the fixing member 300 and the first bracket 1 or the second bracket 2. This reduces the dynamic impact force generated by frequent opening and closing operations, improves the stability of the hinge structure 100's opening and closing, and reduces the noise of the hinge structure 100's opening and closing.
[0072] like Figure 1 , Figure 2 as well as Figure 4 As shown, a second connecting hole 22 is provided on the second bracket 2, and the second connecting member 9 passes through the second connecting hole 22 and extends into the fixing member 300 to connect with the fixing member 300. Using the above structural form, the connection between the second bracket 2 and the fixing member 300 is achieved.
[0073] In this embodiment, there are multiple second connection holes 22, and the multiple second connection holes 22 are arranged one-to-one along the extension direction of the second bracket 2, and each second connection hole 22 corresponds to the second connector 9.
[0074] In practical use, the first support 1 and the second support 2 are sheet-like; the first support 1 and the second support 2 are made of stainless steel. In other embodiments, the materials used for the first support 1 and the second support 2 can be adjusted according to changes in the usage environment, for example, by using a galvanized sheet surface coating process.
[0075] In this embodiment, the second bracket 2 has a first groove 23 on the side away from the fixing member 300, and the first groove 23 is connected to the second connecting hole 22 for accommodating the second connecting member 9.
[0076] like Figure 6 As shown, this embodiment also provides a water purifier 1000, which includes a hinge structure 100. Specifically, the hinge structure 100 is applied to the water purifier 1000. Using the above structure, the first bracket 1 and the second bracket 2 are connected by a rotating shaft 3, and the rotation direction is parallel to the opening and closing direction of the salt-adding body 200 relative to the fixing member 300. This ensures that the salt-adding body 200 operates smoothly and steadily during opening and closing, effectively reducing inconvenience and potential damage risks caused by shaking or displacement. Furthermore, the first bracket 1 and the second bracket 2 are detachably connected by the rotating shaft 3, so that if one of the first bracket 1 or the second bracket 2 is damaged, only the damaged first bracket 1 or the second bracket 2 needs to be replaced for normal use, reducing operating costs.
[0077] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
