DETAILED DESCRIPTION

[0030] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0031] refer to Figures 1 to 7 As shown, the utility model discloses a multifunctional switching structure, including a waterway body 1, a first control valve 2, a second control valve 3, a force transmission rod 4, a first knob 5 and a button 6;

[0032] The first control valve 2 is a push-type valve core, and the second control valve 3 is a rotary valve core, and they are respectively installed in the waterway body 1, and the control ends of the two are facing the same direction;

[0033] One end of the force transmission rod 4 is pivotally connected to the surface of the waterway body 1 and is opposite to the control ends of the first control valve 2 and the second control valve 3. The force transmission rod 4 is provided with a through hole 41 opposite to the control end of the second control valve 3.

[0034] One end of the first knob 5 is rotatably inserted into the through hole 41 and is coaxially connected to the control end of the second control valve 3, and the other end thereof is recessed to form a movable groove 51, and a movable hole 511 is provided at the bottom of the movable groove 51;

[0035] The button 6 is axially movable in the movable groove 51 , and is provided with a protruding arm 61 penetrating through the movable hole 511 , and the protruding arm 61 abuts against the surface of the force transmission rod 4 .

[0036] Through the above solution, the utility model integrates the button 6 into the first knob 5, and the user can control the rotary second control valve 3 by turning the first knob 5. The perforation 41 prevents the force transmission rod 4 from being touched when the first knob 5 is turned, or the user can Fig.10 As shown, by pressing the button 6 to push the force transmission rod 4, the force transmission rod 4 presses the control end of the first control valve 2 to control the push-type first control valve 2, thereby concentrating the operating positions of the two control valves of the shower on the same place on the surface of the shower, which is convenient for user operation and the surface of the product is relatively simple and beautiful.

[0037] A specific embodiment of the above-mentioned multifunctional switching structure is shown below.

[0038] In this embodiment, the first control valve 2 is the switch valve of the shower, the second control valve 3 is the diverter valve of the shower, and also includes a third control valve 7 of a rotary valve core and a second knob 8. The third control valve 7 is the thermostatic valve of the shower. The third control valve 7 is installed in the water channel body 1. The second knob 8 is coaxially connected to the control end of the third control valve 7 to realize the control of the third control valve 7. After adding the third control valve 7, there are only two switch positions on the surface of the shower product, one of which is the switch position of the first control valve 2 and the second control valve 3, which controls the switch and direction of the water flow (i.e., the water outlet mode), and the other is the third control valve 7, which controls the water temperature.

[0039] In this embodiment, the control end of the first control valve 2 is connected to the other end of the force transmission rod 4 by screws, and the second control valve 3 is located between the two ends of the force transmission rod 4, that is, between the pivot end of the force transmission rod 4 and the first control valve 2. When the button 6 is pressed, the non-end position of the force transmission rod 4 will be pushed, and the stroke of the button 6 can be enlarged to the control end stroke of the first control valve 2 according to a certain proportion, so that the user only needs to press the button 6 a short distance to control the first control valve 2, which is conducive to a more compact product structure design, and there is no need to reserve a large moving space for the button 6 on the first knob 5.

[0040] The surface of the water channel body 1 is detachably mounted with a pivot seat 9 by means of screw locking or the like, one end of the force transmission rod 4 is provided with a rotating shaft 42 rotatably connected to the pivot seat 9, and the pivot seat 9 is provided with a C buckle 91 for clasping the rotating shaft 42. The detachable pivot seat 9 means that the pivot seats 9 of different shapes and sizes can be replaced according to different product design requirements, and the product design adjustment is more flexible.

[0041] The force transmission rod 4 protrudes toward both sides at a position corresponding to the first knob 5 to form side wings 43 , and the side wings 43 are used to increase the width and strength of a part of the force transmission rod 4 to bear the pressure from the button 6 and prevent breakage.

[0042] One end of the first knob 5 is provided with a boss 52 penetrating through the through hole 41 , and the boss 52 is key-connected to the control end of the second control valve 3 to achieve coaxial rotation, thereby transmitting the torque of the user turning the first knob 5 to the control end of the second control valve 3 .

[0043] The number of the protruding arms 61 is designed to be multiple, and they are arranged at equal angles around the center line of the button 6, and the corresponding movable groove 51 of the first knob 5 is also provided with multiple movable holes 511. The design of multiple protruding arms 61 can make multiple contact points between the button 6 and the force transmission rod 4, and no matter how the first knob 5 is rotated, it can be ensured that several contact points are stably in contact with the force transmission rod 4.

[0044] A hook 62 is provided on the side of the convex arm 61 to hook on the edge of the movable hole 511 to prevent the button 6 from falling out of the movable groove 51 of the first knob 5 due to the reaction force generated by the reset of the control end of the first control valve 2 .

[0045] The first control valve 2 and the third control valve 3 are both fixed on the water channel body 1 through limiting nuts.

[0046] refer to Figures 8 to 10 As shown, the utility model also discloses a shower device, including the above-mentioned multifunctional switching structure and a housing 10, wherein the housing 10 covers the multifunctional switching structure, and only the first knob 5, the second knob 8, and the water inlet and outlet interfaces are exposed.

[0047] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
