Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a water mixing valve handle. Background Art

[0002] Nowadays, people often enjoy the convenience brought by mixing valves in their daily lives. Whether it is a faucet or a shower device, mixing valve technology is used. The handle, as a component that controls the mixing valve, is the most common contact for people. Just turn the handle to control the mixing valve to get different water outlet temperatures. Figure 1 As shown, the existing valve seat 10' for installing a water mixing valve generally includes a positioning groove 11' for installing and positioning the water mixing valve, a hot water hole 12', a cold water hole 13' and a water mixing hole 14'. Figure 2 As shown, in order to adapt to the valve seat 10', the angle between the diagonal line of the mounting hole 22' in the existing handle 20' for inserting the valve shaft of the water mixing valve and the axis of the operating part 21' is 45 degrees. Figure 3 As shown, when the mixing valve adopting this design is in the closed state, the handle 21' is in the vertical position. If the user wants to rotate the handle 21' to the handle 31' position to open the mixing valve, the conventionally processed positioning groove 11', hot water hole 12', cold water hole 13' and mixing water hole 14' are evenly and symmetrically distributed along the axis of the water pipe, which also causes the position of the handle 31' to interfere with the bathroom wall, thereby affecting the normal use of the user.

[0003] like Figure 4 As shown, the prior art provides a solution, the valve seat 40' includes a positioning groove 41', a hot water hole 42', a cold water hole 43' and a mixing water hole 44' for the installation and positioning of the water mixing valve, and adopts a dislocation processing method so that the positioning groove 41', the hot water hole 42', the cold water hole 43' and the mixing water hole 44' are staggered with the axis of the water pipe to form a certain angle. When the water mixing valve is in a closed state, the handle 21' will be in a tilted state away from the wall, and the rotation range of the handle 21' is on the side of the water pipe away from the wall, and is not interfered by the wall.

[0004] The processing cost of a single valve seat made by the offset processing method in this scheme will be 20 yuan more expensive than that of a single valve seat made by the conventional processing method. This is not conducive to cost control for large-scale processing. In addition, most valve seats on the market are made by conventional processing methods, and the cost for users to replace the entire valve seat is also high. Utility Model Content

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] This embodiment provides a mixing valve handle 1, asFigures 5 to 9 As shown, it includes a handle housing 2. On one side of the handle housing 2, an operation part 3 for the user to grip and rotate is convexly provided, so as to facilitate adjusting the water temperature through the operation part 3. An inner cavity 21 is formed in the handle housing 2. A square mounting hole 4 with an opening facing the mixing valve shaft is provided in the inner cavity 21. The size of the square mounting hole 4 is the same as that of the mixing valve shaft on the market, and it can be adapted to the existing mixing valve. As Figure 6 shown, the angle A between a diagonal line 6 of the square mounting hole 4 and the axis 5 of the operation part 3 is less than 45 degrees, and the angle B between the other diagonal line 7 of the square mounting hole 4 and the axis 5 of the operation part 3 is less than 135 degrees. When the handle 1 is installed on the mixing valve shaft, when the mixing valve is in the closed state, the handle 1 is in an inclined state. Therefore, when the user rotates the handle 1, the operation part 3 can avoid interference with the wall, and the structure is simple.

[0029] Furthermore, as Figure 7 shown, in this embodiment, a diagonal line 6 of the square mounting hole 4 is parallel to the axis 5 of the operation part 3, and the other diagonal line 7 of the square mounting hole 4 is perpendicular to the axis 5 of the operation part 3. This is the preferred setting method of the square mounting hole 4. As Figure 9 shown, when both the cold water adjustment angle and the hot water adjustment angle are 45 degrees, a diagonal line 6 of the square mounting hole 4 in this embodiment is parallel to the axis 5 of the operation part 3, and the other diagonal line 7 of the square mounting hole 4 is perpendicular to the axis 5 of the operation part 3. When the handle 1 is installed on the mixing valve shaft, when the mixing valve is in the closed state, the handle 1 is in an inclined state away from the wall side. Whether the handle 1 is rotated to position C to adjust the cold water or the handle 1 is rotated to position D to adjust the hot water, the operation part 3 of the handle 1 will not interfere with the wall, and the design is user-friendly.

[0030] As Figure 5 shown, a cylindrical inner cavity 21 is formed in the handle housing 2. The cylindrical inner cavity 21 is provided with a closed end 22 and an open end 23. The square mounting hole 4 is fixedly arranged at the closed end 22 of the cylindrical inner cavity 21, and the opening of the square mounting hole 4 faces the open end 23 of the cylindrical inner cavity 21, ensuring that the mixing valve shaft can be firmly inserted into the square mounting hole 4, and the water outlet state can be more accurately controlled by driving the handle 1 to rotate through the operation part 3.

[0031] As Figure 5 shown, a stepped convex strip 41 is provided at each corner of the square mounting hole 4, and the stepped convex strip extends from the opening of the square mounting hole 4 to the closed end 22 of the cylindrical inner cavity 21. The stepped convex strip 41 in this embodiment provides an additional fixing point for the mixing valve shaft. When the valve shaft is inserted into the square mounting hole 4, these convex strips 41 can closely abut against the surface of the valve shaft, increasing the friction force and preventing the handle 1 from loosening when rotating.

[0032] AsFigure 8 As shown, the end 10 of the handle housing 2 on the side away from the operating part 3 is inclined towards the closed end 22 of the cylindrical inner cavity 21. Since the rotational operation of the mixing valve handle 1 is for water temperature adjustment, and the pivoting operation away from the rotational path is for adjusting the water flow rate, when the operating part 3 of the handle 1 is pivoted in this embodiment, the end 10 of the handle housing 2 on the side away from the operating part 3 is inclined towards the closed end 22 of the cylindrical inner cavity 21, serving as a clearance function to avoid interference between the handle housing 2 and the valve seat.

[0033] As Figure 5 shown, the operating part 3 is a cylindrical connecting rod 31. One end of the cylindrical connecting rod 31 is fixedly connected to the handle housing 2. The angle between one diagonal 6 of the square mounting hole 4 and the axis 5 of the connecting rod 31 is less than 45 degrees, and the angle between the other diagonal 7 of the square mounting hole 4 and the axis 5 of the connecting rod 31 is less than 135 degrees. Since the closed end 22 of the handle housing 2 is circular, the operating part 3 in this embodiment is set as a cylindrical connecting rod 31, which can not only improve the aesthetics of the handle 1, but also facilitate the user to grasp and rotate. The structure is simple, and in other embodiments, the operating part 3 can also be set in other shapes according to actual needs.

[0034] Furthermore, a first threaded hole is provided on the handle housing 2. One end of the cylindrical connecting rod 31 is provided with threads, and one end of the cylindrical connecting rod 31 is fixedly connected to the handle housing 2 through threaded engagement with the first threaded hole. In this embodiment, the threaded connection not only has high connection reliability and good stability, but also is beneficial to production and processing, and is convenient for the user to assemble. The design is user-friendly, and in other embodiments, other connection methods can also be adopted.

[0035] Furthermore, it further includes a bolt. The mixing valve shaft is provided with a second threaded hole. As Figure 5 shown, a first through hole 8 is provided at the position of the square mounting hole 4 that matches the mixing valve shaft, and a second through hole 9 is provided at the position of the handle housing 2 that matches the first through hole 8. The mixing valve shaft is inserted into the square mounting hole 4, and the bolt passes through the first through hole 8 and the second through hole 9 and cooperates with the second threaded hole to achieve locking and fixing. In this embodiment, through the cooperation of the bolt and the second threaded hole, a firm connection between the mixing valve shaft and the handle housing 2 is achieved, which can ensure that the handle 1 will not loosen when the user rotates the handle 1, and at the same time simplifies the process of installing the handle 1 on the mixing valve shaft, and is convenient for disassembly.

[0036] Furthermore, the handle housing 2 and the square mounting hole 4 in this embodiment are integrally formed. The integral forming process makes the handle housing 2 and the square mounting hole 4 a whole, reducing the connection points between components, thereby enhancing the integrity and stability of the structure. It reduces the separate processing and assembly processes of multiple components, thus improving production efficiency. At the same time, it reduces the processing procedures and labor costs, helping to reduce the production cost.

[0037] The usage process of the present utility model is as follows:

[0038] The user first removes the existing handle 1 from the valve seat, then aligns the square mounting hole 4 of the handle 1 of the present utility model with the mixing valve shaft and inserts it for positioning, and locks and fixes it by passing a bolt through the first through hole 8 and the second through hole 9 of the housing 2 and cooperating with the second threaded hole, thus completing the installation. After the handle 1 is installed on the mixing valve shaft, when the mixing valve is in the closed state, the handle 1 is in an inclined state, and there will be no interference between the user rotating the operating portion 3 of the handle 1 and the wall.

[0039] The orientation terms mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, so they may change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0040] The above is only the preferred embodiment of the present utility model and does not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
