Description

Technical Field

[0001] The utility model relates to the technical field of showers, in particular to a shower device and a hidden knob structure thereof. Background Art

[0002] In existing bathroom equipment, the knobs for adjusting the temperature or switching the water function are often protruding from the surface of the shower, such as the thermostatic knob of the storage shower, the concealed adjustment knob, etc. The protruding knob makes the appearance of the whole set of products less concise and beautiful, and is particularly easy to accumulate dirt and difficult to clean. For this reason, the industry has designed a push-type hidden knob. When it needs to be rotated and switched, the knob can be pressed to pop out for twisting operation. When it is not needed, the knob can be hidden by pressing it again.

[0003] In the existing structures of push-type hidden knobs, the knob part often passes through the housing and is directly fixed on the valve core of the control valve. The control valve is assembled on the waterway body, and the waterway body is fixed in the housing or fixedly connected to the pipe. The assembly process of these parts will accumulate a certain amount of coaxiality tolerance, plus the coaxiality tolerance of the parts themselves when they are produced. In order to adapt these coaxiality tolerances to ensure the smooth pressing and rotation of the push-type hidden knob, either the gap between the knob and the housing needs to be made very large, which seriously affects the appearance of the product. In addition, the gap that is too large is easy to hide dirt and is difficult to clean. Alternatively, the gap between the two should be within an acceptable range, but the product size and parts assembly requirements are very high, the production and assembly costs are extremely high, and it is difficult to mass produce. Utility Model Content

[0004] The utility model aims to provide a shower device and a hidden knob structure thereof, which solves the problems existing in the prior art and can reduce the requirements for coaxiality when assembling parts. The knob can be used smoothly without leaving a large gap between the knob and the housing.

[0005] In order to achieve the above object, one of the solutions of the utility model is:

[0006] A hidden knob structure comprises an outer shell, a water channel body, a control valve, an adapter seat, a sleeve, a push rod, a knob and a swinging assembly; the outer shell is provided with a movable hole; the water channel body is installed in the outer shell; the control valve is installed on the water channel body and is opposite to the movable hole; the adapter seat is coaxially connected to the control end of the control valve and is provided with a first slide groove extending radially along the adapter seat; the sleeve is fixedly installed in the movable hole, and the end surface of the sleeve facing the control valve is provided with a second slide groove extending radially along the sleeve; the push rod is pressed and telescopically engaged on the end surface of the sleeve facing away from the control valve; the knob is penetrated through the movable hole and fixed relatively to the telescopic end of the push rod; the swinging assembly comprises a sliding block slidably engaged in the second slide groove, and a swing rod one end of which is pivotally engaged with the sliding block, and the other end of the swing rod is slidably engaged in the first slide groove.

[0007] The adapter is spline-connected to the control end of the control valve via a spline.

[0008] One end of the first sliding groove is a closed end, and the other end thereof is connected to the peripheral surface of the adapter seat.

[0009] The extension directions of the first sliding groove and the second sliding groove are perpendicular to each other.

[0010] The hidden knob structure further comprises a fixing seat fixed in the movable hole; the fixing seat is provided with a mounting groove for mounting the sleeve, and a through hole is provided at the bottom of the mounting groove for the sliding block to penetrate.

[0011] A ballpoint pen mechanism is designed between the push rod and the sleeve, so that the push rod performs a rotational motion when pressed and changes the telescopic position on the end surface of the sleeve.

[0012] The hidden knob structure also includes a knob frame fixedly connected to the telescopic end of the push rod, the knob buckle is connected to the knob frame, and a limit block is swingably connected to the knob frame, and the limit block is movably hooked on the inner wall of the movable hole.

[0013] The second solution of the utility model is:

[0014] A shower device comprises the hidden knob structure.

[0015] After adopting the above technical solution, the utility model has the following technical effects:

[0016] The knob of the utility model can realize the telescopic cooperation of the knob at the movable hole through the push-type telescopic cooperation of the push rod and the sleeve, that is, the knob can be hidden when not in use, and the knob can be popped out by pressing the knob when it is needed to be used so as to turn the knob; the sleeve and the adapter seat are transmitted through the swing assembly, and the swing rod and the sliding block of the swing assembly are in a pivotal relationship, and the two are respectively slidably cooperated with the first slide groove of the adapter seat and the second slide groove of the sleeve, and the slide groove only allows the corresponding accessories to move in a straight line, and at the same time, the torque when the knob is turned can be transmitted to realize the driving of the knob to the control valve. At the same time, due to the pivotal cooperation relationship between the swing rod and the sliding block, and the sliding cooperation relationship between the swing rod and the first slide groove, and the sliding block and the second slide groove, the coaxiality tolerance and installation tolerance generated between the accessories of the utility model are absorbed by the swing assembly. During installation, it is only necessary to ensure the coaxiality of the knob and the shell, which is easier to install, and there is no need to reserve a large gap between the knob and the shell to use the knob smoothly, and the appearance of the product is more beautiful and not easy to get dirty.
