Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] Referring to the accompanying drawings, a knob mounting structure includes a mating knob assembly and a body. The knob assembly controls the operation of the body, the main component of which is a valve core. The knob assembly controls the rotation of the valve core to achieve the proportion of hot and cold water entering the valve core, thereby completing the temperature adjustment. A bushing 10 is provided between the body and the knob assembly. The bushing has at least two sliding grooves 11 connected end-to-end. Each sliding groove has an upper stop point A and a lower stop point B. The knob assembly has a guide post 21 that can move within the sliding groove. The knob assembly is also connected to a spring 22. The knob assembly can be pressed and moved axially X relative to the body under the action of the spring, so that the guide post can switch between the upper and lower dead points to realize the switching of the axial position of the knob assembly relative to the body. If the mounting structure is installed inside the wall, when the guide post is at the lower dead point, the outer wall of the knob is flush with the wall surface C. At this time, the knob is not in use. By pressing and the action of the spring, the guide post moves from the lower dead point to the upper dead point. At this time, the knob protrudes from the wall surface and can be rotated to control the valve core.

[0030] Preferably, the bushing has at least two connected sliding grooves on its outer periphery. The sliding grooves are W-shaped, with the upper end of the inverted V-shape in the middle of the sliding groove forming the lower stop point, and the upper ends of both ends of the sliding groove forming the upper stop point. In use, the bushing can rotate relative to the body.

[0031] Furthermore, the knob assembly includes a movable member 20, the peripheral sidewall of which is provided with a pair of matching notches 23, forming an elastic arm 24. The inner periphery of the elastic arm is provided with a guide post that can move within a groove. The groove is provided with a stepped surface that can form a dimensional difference, allowing the guide post to move in one direction within the groove. In other words: the guide post is connected to an elastic arm, ensuring that the guide post can move along the groove of the bushing; the groove has multiple steps, ensuring that the guide post can move directionally within the groove; and the bushing rotates along its axis under the drive of the guide post.

[0032] Specifically, the slide groove includes a long descending section 12 and a long ascending section 13 located on both sides, and a short ascending section 14 and a short descending section 15 located in the middle. These four sections form a W-shaped slide groove. The guide post can move within the slide groove in the order of the long descending section, the short ascending section, the short descending section, and the long ascending section. A first step surface 31 is provided between the long descending section and the short ascending section, a second step surface 32 is provided in the middle of the short ascending section, and a third step surface 33 is provided in the middle of the long descending section. A fourth step surface 34 is provided between the long ascending section of one slide groove and the long descending section of another slide groove connected to it. This allows the guide post to move only in one direction. In other words, if the moving part does not rotate but only moves axially, the bushing can only rotate in one direction. Moreover, as the guide post moves in each section, the depth of these slide grooves gradually decreases along the direction of the guide post's movement, thus forming a stepped surface. This also allows for the compression deformation of the elastic arm, keeping the guide post within the slide groove under the action of the elastic arm.

[0033] Furthermore, the knob assembly also includes a knob 40 and a knob base 50. The knob can be fitted onto the outer periphery of the knob base, and the knob base can rotate synchronously and move axially with the knob. The movable component is disposed on the inner periphery of the knob base. A protrusion 25 is provided on the outer periphery of one end of the movable component. The protrusion can also be connected to an elastic component 26. A snap-fit ​​hole 51 is provided on the peripheral side wall of the knob base, which can engage with the protrusion. The knob base can rotate synchronously and move axially with the movable component.

[0034] Preferably, the main body includes a valve core 60 and a base 70. The base is located on the outer periphery of the valve core and can be connected to a knob seat. The knob seat can rotate synchronously with the base and can move axially relative to the base. The bushing can be engaged with the base. The base includes an inner ring 71 and an outer ring 72. The knob seat can be adapted to the outer periphery of the outer ring. The bushing is located on the outer periphery of the inner ring. An outwardly protruding elastic protrusion 73 is provided on the upper circumference of the inner ring, and the elastic protrusion can abut against the upper end of the bushing. At the same time, the inner periphery of the inner ring can be engaged with the rotating part 61 of the valve core to drive its rotation, thereby controlling the two inlets of the valve core.

[0035] More specifically, this utility model features a sliding groove on the bushing, and a movable component with an elastic arm and a guide post. The guide post slides within the sliding groove of the bushing, moving between the long downward section and the short upward section, before being locked by the inverted V-shaped mechanism at the lower end, forming a lower stop point. Upon pressing again, the guide post continues to slide within the sliding groove (between the short downward section and the long upward section), sliding to the upper end of the groove under the action of a spring, forming an upper stop point, thus completing one cycle. Simultaneously: 1. The guide post of the movable component slides within the bushing sliding groove, and the stepped surface within the groove forces the guide post to slide in a fixed direction; 2. The lower end of the bushing has an inverted "V"-shaped structure, allowing the guide post to be fixed within the V-shaped groove, thus concealing the knob; 3. The guide post is positioned at the elastic wall, facilitating its sliding within the bushing sliding groove and preventing it from detaching.
