Description

Technical Field

[0001] The utility model relates to the technical field of shower heads, in particular to a button linkage structure of a shower head. Background Art

[0002] In some shower products, in addition to the ordinary water splash function, special functions such as spray gun water and water pause are added to meet the special needs of users. Among them, the water output of the spray gun water function is relatively strong and will not be used in normal bathing. If the water pause function is set on the button for switching ordinary water splash, it will cause poor user experience (the process of switching water splash requires multiple presses). Therefore, such special functions usually need to be set with independent buttons for convenient operation by users. Therefore, showers with special functions are all operated in a double-button control mode. One button is used to link the valve stem in the water diversion body to achieve the switch between ordinary water splash and special functions, and keep the water flowing to the water outlet panel under the action of the spring. The possible problem is that when the button is pressed to switch the shower to the special function mode, the valve stem will compress the spring under the action of water pressure and keep the position unchanged, so that the shower will maintain the special function mode. As long as the switch of the shower is not turned off, the spring cannot reset the valve stem. At this time, if you need to switch to the water outlet mode of ordinary water splash, you need to turn off the switch of the shower first. The operation is more complicated and the user experience is poor. Utility Model Content

[0028] The water diversion body 1 is provided with a water passage cavity 11, and the water passage cavity 11 is provided with two water outlets in the axial direction, and a water inlet 111 located between the two water outlets, and the two water outlets are respectively connected to the first water outlet body 2 and the second water outlet body 3, and the first water outlet body 2 has multiple waterways, that is, different water outlet styles are realized;

[0029] The valve stem 4 is axially movable in the water passage chamber 11, and its lower part realizes the on-off control between the water inlet 111 and the two water outlets;

[0030] The rotating water distribution member 5 is rotatably matched with the first water outlet body 2 to switch the water path of the first water outlet body 2;

[0031] The ratchet 6 is arranged on the surface of the first water outlet 2 and is coaxially connected to the rotating water distribution member 5;

When the user needs to switch the water outlet mode of the second water body 3 to the water outlet of the first water body 2, he only needs to press the second button 20 again to make the swing block 9 swing. When the swing block 9 pushes the push rod 7 to slide, the inclined surface 71 of the push rod 7 will contact the end of the linkage rod 8 and lift the linkage rod 8, thereby linking the valve stem 4 to move axially. The user no longer needs to shut off the water inlet of the shower, the operation becomes simpler, and the user experience is improved.

[0037] The following is a detailed description of the first embodiment.

[0038] In the first embodiment, the first water outlet 2 is a water outlet panel of a shower head, and the second water outlet 3 is a spray gun structure of a shower head. In addition, the water diversion body 1, the first water outlet 2, and the second water outlet 3 can be connected separately or integrally, which does not affect the realization of the technical solution of the utility model.

[0039] The two water outlets of the water passage chamber 11 are the first water outlet 112 and the second water outlet 113. The first water outlet 112 is located at the bottom of the water passage chamber 11 and communicates with the first water outlet 2. The second water outlet 113 is located on the side wall of the water passage chamber 11 and communicates with the second water outlet 3. The lower part of the valve stem 4 is provided with a sealing part 41. The sealing part 41 moves and blocks the connection between the water inlet 111 and the first water outlet 112 or the second water outlet 113 as the valve stem 4 moves axially in the water passage chamber 11. In the first embodiment, a sealing ring is sleeved on the circumference of the sealing part 41 to improve the sealing performance.

[0040] Furthermore, the water passage chamber 11 is provided with a water passage member 30 through which the valve stem 4 can movably pass, and a water sealing cover 40 detachably connected to the opening of the water passage chamber 11; water from the water inlet 111 flows to the second water outlet 113 through the water passage member 30, so that when the valve stem 4 moves axially, the upper and lower surfaces of the sealing portion 41 thereof can movably seal the first water outlet 112 or the water passage member 30, and the water sealing cover 40 can prevent water leakage and prevent the water passage member 30 from escaping from the water passage chamber 11.

[0041] The end of the rotating shaft of the rotating water distribution member 5 passes through the first water outlet 2 and is key-connected with the ratchet 6 to achieve a coaxial connection between the two. When the ratchet 6 rotates, it can drive the rotating water distribution member 5 to rotate synchronously, thereby changing the water path in the first water outlet 2. The first water outlet 2 is a conventional water outlet of a shower head, and the method for implementing the internal water path switching is a conventional and mature technology, which will not be elaborated here.

[0042] A first spring 50 is arranged between the end surface of one end of the push rod 7 and the first water outlet body 2, which is used to provide elastic force to reset the push rod 7; an elastic telescopic member 72 engaged with the ratchet 6 is arranged on the side of the push rod 7 opposite to the ratchet 6. When the push rod 7 is reset, the elastic telescopic member 72 will retract and pass over the ratchet teeth of the ratchet 6 under the reaction force of the ratchet 6, so that the ratchet 6 will not be driven to rotate when the push rod 7 is reset; at the same time, when the push rod 7 is reset, it will drive the pendulum block 9 to reset in the opposite direction, that is, drive the second button 20 to reset.

[0043] A second spring 60 is disposed between the first button 10 and the first water outlet 2 to provide elastic force to reset the first button 10 .

[0044] In the first embodiment, the first button 10 and the second button 20 are both provided with hooks to prevent them from falling out of the shower housing 100 .

[0045] A through hole 42 is provided on the upper part of the valve stem 4; the middle part of the linkage rod 8 is located in the through hole 42, one end of the linkage rod 8 is located above the inclined surface 71, and the other end of the linkage rod 8 is pivotally connected to the upper surface of the water diversion body 1, so that the linkage rod 8 is relatively fixedly installed on the water diversion body 1, and can swing its end opposite to the inclined surface 71 with the axial movement of the valve stem 4. When the valve stem 4 is pressed, the end of the linkage rod 8 drops to a position at the same height as the inclined surface 71. When the push rod 7 is subsequently pushed, the linkage rod 8 can be lifted up through the inclined surface 71, thereby linking the valve stem 4 to rise.

[0046] One end of the pendulum block 9 is provided with a protrusion 91 opposite to the end face of the push rod 7, and the surface of the protrusion 91 is chamfered to avoid sharp contact with the end face of the push rod 7, so that it can contact with and push the push rod 7 more smoothly.

[0047] refer to Figure 7 and Figure 8As shown, the second embodiment of the utility model also discloses a button linkage structure of a shower head, which is different from the first embodiment in that:

[0048] In the second embodiment, the second water outlet 3 is not provided in the shower housing 100, and only the first water outlet 2 is provided. Then, the corresponding water passage chamber 11 is only provided with the first water outlet 112 which is connected with the first water outlet 2. Therefore, it can be understood that the function of the first button 10 is to realize the water pause function of the shower, that is, when the first button 10 is pressed, the valve stem 4 and the sealing portion 41 at the lower part thereof are driven to move axially to realize the blocking of the first water outlet 112, and the first water outlet 2 no longer discharges water, thereby realizing the water pause function; when the user needs the first water outlet 2 to discharge water again, that is, the shower needs to realize the water discharge function corresponding to the first water outlet 2, the user only needs to press the second button 20 again to make the swing block 9 swing, and when the swing block 9 pushes the push rod 7 to slide, the inclined surface 71 of the push rod 7 will contact with the end of the linkage rod 8 and lift the linkage rod 8, thereby linking the valve stem 4 to move axially to open the first water outlet 112, and the first water outlet 2 discharges water again.

[0049] 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.
