Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a mixing faucet. Background Technology

[0002] A mixing faucet uses a mixing valve inside its housing to mix incoming cold and hot water in a certain ratio to produce water at a specific temperature before outputting it. The mixing valve is controlled by an operating handle connected to its stem. Generally, the operating handle swings in both the vertical and horizontal directions when operating the mixing valve. The vertical swing opens and closes the mixing valve, while the horizontal swing controls the water temperature. However, in existing mixing faucets, the operating handle swings freely in both directions. This can lead to a situation where, after the user has adjusted the operating handle to the desired water temperature, they may accidentally activate the horizontal swing of the operating handle, causing a sudden change in the water temperature and affecting the user experience.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a mixing faucet, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A mixing faucet includes a housing, a mixing valve, and an operating handle. The mixing valve is disposed within the housing, and a mounting sleeve surrounding the mixing valve is fixedly connected to the housing. The operating handle is fixedly connected to the valve stem of the mixing valve, located above the mounting sleeve. A limiting ring is fixedly connected to the mounting sleeve, located on one side in front of the circular base of the operating handle. A limiting block is fixedly connected to the circular base of the operating handle. A plurality of vertical limiting protrusions are formed on the inner wall of the limiting ring. The plurality of limiting protrusions are arranged in a circular array along the limiting ring, forming a limiting groove that matches the limiting block between adjacent limiting protrusions. When the operating handle is swung upward to open the mixing valve, the limiting block enters the limiting groove through the lower opening of the limiting groove. When the operating handle is swung downward to close the mixing valve, the limiting block leaves the limiting groove through the lower opening of the limiting groove.

[0007] Preferably, the lower end of the limiting ring is formed with a mounting ring that matches the mounting sleeve, the mounting ring is sleeved outside the mounting sleeve and a first mounting bolt that passes through the mounting sleeve is screwed onto the mounting ring.

[0008] Preferably, a plurality of positioning protrusions are formed on the inner wall of the mounting ring, and a plurality of positioning grooves that match the positioning protrusions and penetrate the mounting sleeve upward are provided on the outer wall of the mounting sleeve. The positioning protrusions are inserted into the positioning grooves through the upper opening of the positioning grooves.

[0009] Preferably, the limiting block has an arc-shaped mounting plate that matches the circular base of the operating handle, and a plurality of second mounting bolts screwed onto the circular base of the operating handle are provided on the mounting plate.

[0010] Preferably, the inner wall of the limiting ring is spherical, the surface of the limiting block facing the inner wall of the limiting ring is spherical and matches the inner wall of the limiting ring, and the limiting protrusion extends along the inner wall of the limiting ring in an arc shape.

[0011] Preferably, an elastic plate is fixedly connected to the mounting plate, and a positioning protrusion matching the limiting groove is formed on the free end of the elastic plate. When the operating handle swings downward to close the mixing valve, the positioning protrusion is located in the limiting groove.

[0012] Preferably, the inner end of the limiting protrusion is arc-shaped, and the outer end of the positioning protrusion is arc-shaped.

[0013] In summary, the beneficial effects of this utility model are as follows: when the operating handle is swung upward to open the faucet, the limiting block is located in the limiting groove and cooperates with the limiting groove to limit the lateral swing of the operating handle, preventing the operating handle from being accidentally touched and causing lateral swing, so that the water temperature of the faucet is stably maintained at the adjusted temperature, thereby ensuring a good user experience when using the faucet. When it is necessary to adjust the water temperature again, the operating handle is swung downward to drive the limiting block out of the limiting groove through the lower opening of the limiting groove.

Detailed Implementation

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] As shown in the figure, a mixing faucet includes a housing 1, a mixing valve 2, and an operating handle 3. The mixing valve 2 is disposed inside the housing 1. A mounting sleeve 4 is fixedly connected to the housing 1, surrounding the mixing valve 2. The operating handle 3 is fixedly connected to the valve stem of the mixing valve 2, located above the mounting sleeve 4. A limiting ring 5 is fixedly connected to the mounting sleeve 4, located on one side in front of the circular base of the operating handle 3. A limiting block 6 is fixedly connected to the circular base of the operating handle 3. Several vertical limiting protrusions 51 are formed on the inner wall of the limiting ring 5. The several limiting protrusions 51 are arranged in a circular array along the limiting ring 5, so that a limiting groove 52 matching the limiting block 6 is formed between two adjacent limiting protrusions 51. When the operating handle 3 swings upward to open the mixing valve 2, the limiting block 6 enters the limiting groove 52 through the lower opening of the limiting groove 52. When the operating handle 3 swings downward to close the mixing valve 2, the limiting block 6 leaves the limiting groove 52 through the lower opening of the limiting groove 52.

[0024] Specifically, the structure in which the limiting ring 5 is fixedly connected to the mounting sleeve 4 is as follows: the lower end of the limiting ring 5 forms a mounting ring 53 that matches the mounting sleeve 4. The mounting ring 53 is sleeved on the outside of the mounting sleeve 4, and a first mounting bolt 54 that passes through the mounting sleeve 4 is screwed onto the mounting ring 53. The mounting ring 53 is securely sleeved on the mounting sleeve 4 by the first mounting bolt 54, thereby fixing the limiting ring 5 on the mounting sleeve 4. The above installation structure facilitates the disassembly and assembly of the limiting ring 5, and does not require much adaptation processing to the existing mixing faucet, thus reducing production costs.

[0025] Specifically, to further enhance the stability of the limiting ring 5 fixedly connected to the mounting sleeve 4, a plurality of positioning protrusions 55 are formed on the inner wall of the mounting ring 53, and a plurality of positioning grooves 41 matching the positioning protrusions 55 and extending upward through the mounting sleeve 4 are provided on the outer wall of the mounting sleeve 4. The positioning protrusions 55 are inserted into the positioning grooves 41 through the upper opening of the positioning grooves 41. When installing the limiting ring 5, the positioning protrusions 55 are inserted into the positioning grooves 41. The relative rotation of the mounting ring 53 and the mounting sleeve 4 is limited by the cooperation between the positioning protrusions and the positioning grooves 41, thereby limiting the relative rotation of the limiting ring 5 relative to the mounting sleeve 4, thus enhancing the stability of the limiting ring 5 fixedly set on the mounting sleeve 4.

[0026] Specifically, the structure in which the limiting block 6 is fixedly connected to the operating handle 3 is as follows: the limiting block 6 has an arc-shaped mounting plate 61 that matches the circular base of the operating handle 3. Several second mounting bolts 62 are threaded through the mounting plate 61 and screwed onto the circular base of the operating handle 3. The mounting plate 61 is fixedly mounted on the circular base of the operating handle 3 by the second mounting bolts 62, thereby realizing the fixed mounting of the limiting block 6 on the circular base of the operating handle 3. The above mounting structure facilitates the disassembly and assembly of the limiting block 6 and does not require much adaptation processing to the existing mixing water tap, thus reducing production costs.

[0027] In the above structure, when the longitudinal and lateral swing of the operating handle 3 drives the valve stem of the mixing valve 2 to open and close the mixing faucet and adjust the water temperature, when the operating handle 3 swings downward to close the faucet, the operating handle 3 drives the limiting block 6 to swing downward within the limiting groove 52, causing the limiting block 6 to exit the limiting groove 52 through the lower opening of the limiting groove 52. This places the limiting block 6 below the lower ends of several limiting protrusions 51. At this time, the limiting block 6 can swing laterally below the limiting protrusions 51, allowing the operating handle 3 to swing laterally. When the operating handle 3 swings laterally to adjust the water temperature to the desired temperature, when the operating handle 3 swings upward to open the faucet, the operating handle 3 drives the limiting block 6 to swing upward, causing the limiting block 6 to enter through the lower opening of the limiting groove 52. When the operating handle 3 is fully opened by swinging the operating handle 3 into the limiting groove 52, the limiting block 6 remains within the limiting groove 52. The matching of the limiting block 6 and the limiting groove 52 limits the lateral swing of the operating handle 3, preventing the operating handle 3 from being accidentally touched and causing lateral swing. This keeps the water temperature of the faucet stable at the adjusted temperature, thus ensuring a good user experience. When the water temperature needs to be adjusted again, the operating handle 3 is swung downwards to drive the limiting block 6 out of the limiting groove 52 through the lower opening. Furthermore, the detachable connection of the limiting ring 5 and the limiting block 6 to the mounting sleeve 4 and the operating handle 3 respectively allows the user to assemble and disassemble the limiting ring 5 and the limiting block 6 according to different usage scenarios, providing a high degree of freedom of use.

[0028] Furthermore, in the above structure, the inner wall of the limiting ring 5 is spherical, and the surface of the limiting block 6 facing the inner wall of the limiting ring 5 is spherical and matches the inner wall of the limiting ring 5. The limiting protrusion 51 extends along the inner wall of the limiting ring 5 in an arc shape. The spherical inner wall of the limiting ring 5 is adapted to the swing trajectory of the limiting block 6 with the operating handle 3. The spherical surface of the limiting block 6 is in contact with the inner surface of the limiting ring 5 when the limiting block 6 moves with the operating handle 3, thereby enhancing the stability of the limiting block 6 when it moves. This allows the limiting block 6 to stably cooperate with the limiting groove 52 to limit the lateral swing of the operating handle 3 and achieve the function of preventing accidental touch.

[0029] Furthermore, based on the above structure, an elastic plate 63 is fixedly connected to the mounting plate 61. A positioning protrusion 64 matching the limiting groove 52 is formed on the free end of the elastic plate 63. When the operating handle 3 swings downward to close the mixing valve 2, the positioning protrusion 64 is located in the limiting groove 52. That is, when the operating handle 3 can swing laterally to adjust the water temperature, the positioning protrusion is located in the limiting groove 52. When the operating handle 3 swings laterally, the elastic swing of the elastic plate 63 causes the positioning protrusion 64 to move in different positions of the limiting groove with the operating handle 3. Switching between 52 and 52 provides a certain amount of damping for the lateral swing of the operating handle 3, making the water temperature adjustment tactile and facilitating operation when adjusting the water temperature. Furthermore, the positioning protrusion 64 keeps the limiting block 6 within the limiting groove 52, ensuring that the limiting block 6 is always aligned with the lower opening of the limiting groove 52. This ensures that when the operating handle 3 swings upward after reaching its lateral position, the limiting block 6 can swing upward with the operating handle 3 and enter the limiting groove 52 through the lower opening of the limiting groove 52 to limit the lateral swing of the operating handle 3, thereby facilitating the use of the faucet.

[0030] Furthermore, based on the above structure, the inner end of the limiting protrusion 51 is arc-shaped, and the outer end of the positioning protrusion 64 is arc-shaped, making the switching action of the positioning protrusion 64 between the limiting grooves 52 at different positions smoother, thereby facilitating the use of the faucet.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
