Description

Technical Field

[0001] This utility model belongs to the field of thermostatic valve technology, and relates to a thermostatic mixing valve, particularly a thermostatic mixing valve with a locking mechanism. Background Technology

[0002] Thermostatic mixing valves mainly achieve the desired water temperature by introducing cold and hot water and mixing them to form a mixed water that is then discharged. This is achieved by using an internal temperature sensor to mix the cold and hot water.

[0003] However, current thermostatic mixing valves lack the function of autonomous and conscious adjustment of water temperature. In other words, users usually rely on their sense of touch to judge the water temperature, which can sometimes lead to water that is too hot or too cold, causing scalding and reducing the user experience.

[0004] Therefore, our company has designed a lockable thermostatic mixing valve that can automatically adjust the water temperature and clearly define the water temperature value. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a thermostatic mixing valve with a locking mechanism, which achieves precise water temperature regulation and enhances the water usage experience.

[0006] The purpose of this utility model can be achieved through the following technical solution: a thermostatic mixing valve with a locking mechanism, the thermostatic mixing valve including a valve body and a handwheel, characterized in that a linkage sleeve is provided between the valve body and the handwheel, and the thermostatic mixing valve further includes a locking component for unlocking the handwheel to realize the rotation temperature adjustment function of the handwheel; The locking assembly includes a locking body, a locking seat, an unlocking block, and several springs. The outer end of the locking body is exposed outside the handwheel, and its inner end extends into the locking seat. The locking seat is fixedly installed inside the handwheel. The upper end of the unlocking block is engaged with the locking body, and its lower end extends into the linkage sleeve. The two ends of the springs abut against the inner wall of the locking body and the inner wall of the locking seat, respectively. The inner peripheral wall of the linkage sleeve has several spaced limiting ribs, and the lower end of the unlocking block has several limiting rods that extend between two adjacent limiting ribs.

[0007] In the aforementioned thermostatic mixing valve with a latch, the bottom of the latch seat has a guide unlocking groove for guiding the movement of the unlocking block.

[0008] In the aforementioned thermostatic mixing valve with a locking mechanism, the handwheel has several positioning ribs for positioning the locking seat, and the linkage sleeve is also provided with a valve cover, the top of which is used to place the bottom of the locking seat.

[0009] In the aforementioned thermostatic mixing valve with a locking mechanism, the handwheel has an integrally formed water temperature marking around its periphery.

[0010] Compared with existing technologies, this locking thermostatic mixing valve has the advantages of precise water temperature regulation and improved water usage experience. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-7As shown, this thermostatic mixing valve with a locking mechanism includes a valve body 1 and a handwheel 2. A linkage sleeve 3 is provided between the valve body 1 and the handwheel 2. The handwheel 2 is fixedly linked to the linkage sleeve 3 by internal thread or other snap-fit ​​method. The thermostatic mixing valve also includes a locking assembly for unlocking the handwheel 2 to realize the temperature adjustment function of the handwheel 2. The locking assembly includes a locking body 4, a locking seat 5, an unlocking block 6, and several springs 7. The outer end of the locking body 4 is exposed outside the handwheel 2, and its inner end extends into the locking seat 5. The locking seat 5 is limited and installed on the handwheel. Inside the lock body 4, the upper end of the unlocking block 6 is engaged with the locking body 4, and its lower end extends into the linkage sleeve 3. The two ends of the spring 7 abut against the inner wall of the locking body 4 and the inner wall of the locking seat 5, respectively. A fixing groove is opened in the inner wall of the locking body 4, and the spring 7 extends into the fixing groove. The inner peripheral wall of the linkage sleeve 3 has several spaced limiting ribs 8. The lower end of the unlocking block 6 has several limiting rods 9 that extend between two adjacent limiting ribs 8. At the same time, the upper end of the unlocking block 6 has a protruding rod that extends into the locking body 4 to play a positioning role. The staggered distribution between the limiting rods 9 and the limiting ribs 8 achieves circumferential limiting of the handwheel 2, locking the handwheel 2. By pressing the locking body 4, the spring 7 is pressed inward, and the limiting rod 9 is disengaged from the groove between the two limiting ribs 8. After continuously pressing the locking body 4 and rotating the handwheel 2 to the desired water temperature position, the locking body 4 is released, the spring 7 returns to its original position, the limiting rod 9 is locked, and the handwheel 2 is positioned.

[0021] Preferably, the bottom of the latch seat 5 has a guide unlocking groove 10 for guiding the movement of the unlocking block 6.

[0022] To elaborate further, the handwheel 2 has several positioning ribs 11 for positioning the locking seat 5, and the linkage sleeve 3 is also provided with a valve cover 12. The top of the valve cover 12 is for the bottom of the locking seat 5 to be placed, so as to fix the position of the locking seat 5.

[0023] To elaborate further, the handwheel 2 has an integrally formed water temperature indicator 13 around its perimeter, a raised indicator on the valve body 1, and an arrow indicator on the linkage sleeve 3 that is driven to rotate by the handwheel 2. The user selects the desired water temperature by using the water temperature indicator and rotates the water temperature indicator 13 and the arrow indicator on the handwheel 2 to the corresponding raised indicator.

[0024] The internal structure of this thermostatic mixing valve, including the inlet end and the inlet gap structure for hot and cold water, is existing technology and will not be described in detail here.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0026] Although this document uses numerous terms such as valve body 1, handwheel 2, linkage sleeve 3, locking body 4, locking seat 5, unlocking block 6, spring 7, limiting rib 8, limiting rod 9, guide unlocking groove 10, positioning rib 11, valve cover 12, and water temperature indicator 13, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
