Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to thermostatic valves. Background Technology

[0002] Most existing quick-release thermostatic valve cores are fixed by adding screw holes to the valve core and screwing the screw into the outer casing to hold the valve core in place. Therefore, screw holes need to be provided on the side wall of the valve core. Furthermore, there is only one limiting point between the valve core and the casing—the screw. When water flows through the valve core, the valve core is prone to tilting around this limiting point under water pressure, resulting in a poor seal and leakage. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a quick-installation and quick-disassembly structure for the valve core assembly, so as to prevent the valve core from tilting and leaking water under water pressure when water is supplied.

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-installation and quick-disassembly structure for a valve core assembly, used to achieve quick-installation and quick-disassembly of the valve core assembly and the housing. The structure includes a housing and a valve core assembly, wherein the valve core assembly includes a pressure cap, an adjusting member, and a valve core, with the adjusting member and the pressure cap disposed on the valve core. The key feature is that the adjusting member drives the pressure cap to move, causing the pressure cap and the adjusting member to respectively form a limiting engagement with the housing; furthermore, the adjusting member drives the pressure cap to move, causing the pressure cap and the adjusting member to respectively release the limiting engagement with the housing.

[0005] In a preferred embodiment: the housing has a chamber for inserting the valve core assembly, and the valve core assembly and at least two regions within the chamber form the limiting fit along the axial direction of the housing.

[0006] In a preferred embodiment: the at least two regions are spaced apart.

[0007] In a preferred embodiment: the pressure cap is disposed outside the side wall of the valve core; the adjusting member is used to drive the pressure cap to move relative to the outer shell from a first position to a second position;

[0008] When the pressure cap is in the first position, the outer diameter of the assembly formed by the adjusting member and the pressure cap is smaller than the inner diameter of the chamber; when the pressure cap is in the second position, the pressure cap abuts against the inner wall of the chamber and is axially limited along the outer shell.

[0009] In a preferred embodiment: the inner wall of the chamber has a groove along the thickness direction of the inner wall, and the pressure cap is provided with a protrusion that cooperates with the groove; when the pressure cap is in the second position, the protrusion is placed in the groove to form a first limiting structure.

[0010] In a preferred embodiment: the outer shell is provided with a clearance opening corresponding to the position of the adjusting member, and the side wall of the adjusting member extends outward to form a limiting wall.

[0011] In a preferred embodiment: the adjusting member moves along a first direction or a second direction under the action of an external force; the adjusting member has a first limit position for moving along the first direction and a second limit position for moving along the second direction, as well as an intermediate position located between the first limit position and the second limit position;

[0012] When the adjusting member moves from the first extreme position to the middle position along the second direction, the adjusting member moves relative to the outer shell, and the limiting wall moves toward the clearance opening; when the adjusting member is in the middle position, the limiting wall abuts against the inner wall of the chamber.

[0013] In a preferred embodiment: the adjusting member further has a limiting portion, which is at least partially located within the clearance opening to form a second limiting structure.

[0014] In a preferred embodiment: when the adjusting member moves from the middle position to the second extreme position along the second direction, the adjusting member is linked with the pressure cover to drive the pressure cover to move from the first position to the second position relative to the outer shell.

[0015] In a preferred embodiment: the adjusting member and the pressure cap are threaded together, and the first direction and the second direction are clockwise and counterclockwise, respectively.

[0016] This utility model also provides a temperature control valve assembly, which uses the quick-release limiting structure of the valve core assembly as described above, wherein the valve core in the valve core assembly is a temperature control valve core.

[0017] This utility model also provides a shower unit equipped with the thermostatic valve assembly described above.

[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0019] 1. The quick-install and quick-disassembly structure of the valve core assembly provided by this utility model is such that the valve core is fixed to the outer shell by the pressure cap and the adjusting component. The valve core itself does not need to be threaded. It is only necessary to install the pressure cap on the valve core. It is compatible with most existing valve core assemblies and there is no need to develop new valve core assemblies.

[0020] 2. The valve core assembly installation method provided by this utility model can achieve the limiting cooperation of the two limiting structures by simply operating the adjusting component in one direction, thereby realizing the installation of the valve core assembly without making the installation process more complicated by adding a limiting structure.

[0021] 3. The quick-installation and quick-disassembly structure of the valve core assembly provided by this utility model only requires one adjusting component to achieve the limiting fit between the two parts, the pressure cap and the adjusting component, and the outer shell. It has fewer parts and lower cost.

[0022] 4. The quick-install and quick-disassembly structure of the valve core assembly provided by this utility model adds at least one new limiting point compared to the traditional one limiting point. The two limiting points can prevent the valve core from tilting around a certain limiting point when water is flowing, thereby effectively preventing the valve core from tilting and leaking when water is flowing.

[0033] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0034] refer to Figures 1-13 This embodiment provides a thermostatic valve assembly, which is used in a shower. The thermostatic valve assembly can be a thermostatic valve core or a conventional temperature-regulating valve core. This embodiment uses a thermostatic valve core, and its structure can be found in the specific structure of the thermostatic valve core in patent CN202123087740.8. The thermostatic valve assembly includes a housing 1 and a valve core assembly 2 with a valve core 21 and a handle 22. The housing 1 is equipped with a cold water inlet connector 11 and a hot water inlet connector 12. The housing 1 is provided with a cold water flow channel 13 connecting the cold water inlet connector 11 and a hot water flow channel 14 connecting the hot water inlet connector 12, as well as a mixed water outlet flow channel 15. The valve core 21 is provided with a cold water inlet, a hot water inlet, and a mixed water outlet. When the valve core assembly 2 is installed with the housing 1, the cold water inlet, the hot water inlet, and the mixed water outlet are respectively connected to the cold water flow channel 13, the hot water flow channel 14, and the mixed water outlet flow channel 15. By rotating the valve core 21 through the handle 22, the water flow area of ​​the cold water inlet and the hot water inlet can be adjusted, thereby adjusting the ratio of cold and hot water in the mixed water to achieve the purpose of adjusting the temperature of the mixed water, thus realizing the basic function of the temperature control valve group.

[0035] To install the valve core assembly 2 and the housing 1, the housing 1 has a chamber 16 at one end along the axial direction for inserting the valve core 21. After insertion, the valve core 21 is fixed in the chamber 16. To this end, the valve core 21 and two areas within the chamber 16 form a limiting fit along the axial direction of the housing 1. Since the number of areas forming the limiting fit is increased to two, and the two areas can be spaced apart, for example, in this embodiment, the two areas are symmetrically distributed along the axial direction of the housing 1. Thus, when water is supplied, if the water pressure causes the valve core 21 to tend to tilt around one area, the other area will prevent the valve core 21 from tilting. Therefore, the valve core 21 can be fixed in its original position, avoiding the problem of leakage caused by one side not sealing properly due to the valve core 21 tilting under water pressure.

[0036] Specifically, in addition to the valve core 21 and the handle 22 for rotating the valve core 21, the valve core assembly 2 also includes a pressure cap 23 disposed on the side wall of the valve core 21. The pressure cap 23 is specifically disposed in a cavity 211 outside the valve core 21 to prevent the pressure cap from moving axially relative to the valve core 21. It also includes an adjusting member 24 for adjusting the relative position of the pressure cap 23 and the outer shell 1. The adjusting member 24 is used to move the pressure cap 23 relative to the outer shell 1 from a first position to a second position.

[0037] When the pressure cap 23 is in the first position, the outer diameter of the assembly formed by the adjusting member 24 and the pressure cap 23 is smaller than the inner diameter of the chamber 16. At this time, the valve core 21, the pressure cap 23, and the adjusting member 24 can be smoothly inserted into the chamber 16. When the pressure cap 23 is in the second position, the pressure cap 23 abuts against the inner wall of the chamber 16 and is axially limited along the outer shell 1, achieving the limitation of the first region. To make the limiting fit more stable and reliable, the inner wall of the chamber 16 has a groove 161 along the thickness direction X of the inner wall, and the pressure cap 23 is provided with a protrusion 231 that cooperates with the groove 161. When the pressure cap 23 is in the second position, the protrusion 231 is placed in the groove 161 and is axially limited along the side wall of the groove 161, forming the first limiting structure. In this embodiment, there are two grooves 161 and two corresponding protrusions 231. In addition to the groove 161 and the protrusion 231, the first limiting structure can also be implemented by using other common limiting structures in the prior art, such as increasing the friction between the pressure cap 23 and the inner wall of the chamber 16.

[0038] To facilitate user operation of the adjusting member 24, a clearance opening 17 is provided on the inner wall of the chamber 16 corresponding to the position of the adjusting member 24. A limiting wall 241 extends outward from the side wall of the adjusting member 24, and the projection of the limiting wall 241 on the inner wall of the chamber 16 is at least partially located outside the clearance opening 17. Since the outer diameter of the limiting wall 241 is larger than the outer diameter of the clearance opening 17, operating the adjusting member 24 allows the limiting wall 241 to abut against the inner wall of the chamber 16. Furthermore, the adjusting member 24 also has a limiting part 242. When the adjusting member 24 moves until the limiting part 242 is at least partially located within the clearance opening 27, the limiting part 242 engages with the inner wall of the clearance opening to form a second limiting structure.

[0039] Specifically, the adjusting member 24 and the pressure cap 23 are connected by threads. The end face of the adjusting member 24 is provided with a slot for inserting a screwdriver, and the pressure cap 23 is provided with a threaded hole 232. By inserting a screwdriver and applying external force, the adjusting member 24 can be rotated in either a first direction (clockwise) or a second direction (counterclockwise) under the action of external force. When the adjusting member 24 rotates in the first direction, it moves away from the inner wall of the chamber 16, thereby retracting the adjusting member 24 into the pressure cap 23. This avoids the protruding adjusting member 24 interfering with the outer shell 1. At this time, the valve core 21 can be removed from the chamber 16, or the valve core 21 can be inserted into the chamber 16 to achieve quick installation and quick removal. Of course, the adjusting member 24 can also be partially exposed outside the pressure cap 23, as long as the adjusting member 24 does not interfere with the outer shell 1 when the valve core 21 is inserted. When the adjusting member 24 rotates along the second direction, it moves towards the inner wall of the chamber 16. During this rotation, in addition to ensuring a limiting fit between the limiting part 242 and the inner wall of the clearance opening 17, the adjusting member 24 also moves the pressure cap 23 from the first position to the second position. Therefore, the adjusting member 24 has a first extreme position for movement along the first direction, a second extreme position for movement along the second direction, and an intermediate position between the first and second extreme positions. When the adjusting member 24 moves from the first extreme position to the intermediate position along the second direction, it moves relative to the pressure cap 23. The limiting wall 241 moves towards the clearance opening 17. When the adjusting member 24 moves to the intermediate position along the second direction, the limiting wall 241 abuts against the inner wall of the chamber, and the limiting part 242 is at least partially placed in the clearance opening to form a second limiting structure. This stage completes the limiting engagement between the limiting part 242 and the inner wall of the clearance opening 17, and also completes the abutment between the limiting wall 241 and the inner wall of the chamber 16, realizing the linkage between the adjusting member 24 and the pressure cap 23. When the adjusting member 24 moves from the middle position to the second limit position along the second direction, since the adjusting member 24 is limited by the inner wall of the chamber 16 and cannot continue to move towards the clearance opening 17, the adjusting member 24 will drive the pressure cap 23 to move, causing the pressure cap 23 to move relative to the adjusting member 24, thereby moving the pressure cap 23 relative to the outer shell 1 from the first position to the second position. This stage completes the limiting engagement of the first limiting structure.

[0040] The installation of the above-mentioned temperature control valve assembly can be simply summarized as follows:

[0041] 1) Insert the valve core 21 of the valve core assembly 2 into the chamber 16 of the housing 1;

[0042] 2) Operate the adjusting member 24 along the second direction until the adjusting member 24 abuts against the inner wall of the chamber 16 to form the second limiting structure;

[0043] 3) Continue operating the adjusting member 24 along the second direction to move the pressure cap 23 from the first position to the second position, so that the pressure cap 23 abuts against the inner wall of the chamber 16 to form the first limiting structure.

[0044] It can be seen that by operating the adjusting member 24 in different directions, the adjusting member 24 can drive the pressure cap 23 to move, so that the pressure cap 23 and the adjusting member 24 respectively form a limiting engagement with the outer shell 1; or the adjusting member 23 can drive the pressure cap 24 to move, so that the pressure cap 23 and the adjusting member 24 respectively release the limiting engagement with the outer shell 1. Thus, quick installation and quick removal of the valve core assembly 2 and the outer shell 1 are achieved.

[0045] If, during step 1, the adjusting member 24 interferes with the chamber 16 and cannot be inserted into the valve core 21, then before step 1, a step is included in which the adjusting member 24 is operated to a first limit position along a first direction.

[0046] This embodiment uses a temperature-controlled valve assembly as an example. However, the quick-release structure between the valve core assembly 2 and the outer casing 1 is not limited to temperature-controlled valve assemblies. Flow valve assemblies or valve assemblies that simultaneously adjust temperature and flow can also use such a quick-release structure to install the valve core assembly 2 and the outer casing 1. Furthermore, it should be noted that while the valve core assembly 2 in this embodiment includes a handle 22, the quick-release structure of the valve core assembly is independent of the handle 22. Replacing the handle 22 with other operating components such as buttons or knobs can achieve quick-release of the valve core assembly 2. Similarly, the above installation method is not limited to temperature-controlled valve assemblies; any installation of the valve core assembly 2 and the outer casing 1 can employ the above installation method.

[0047] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
