[0034] Example

[0035] Combination Figures 1 to 10 As shown, this embodiment provides a concealed button mechanism, including a base with an upper-opening mounting cavity and a button 1 with a lower-opening cavity; it also includes a first elastic element 2, a movable pin 3, an unlocking element 4, an adapter 5, and a switch knob cutting element 6; the adapter 5 is used to connect with the rotation adjustment element of the valve core 27, and the switch knob cutting element 6 is used to connect with the push switch of the valve core 27; the first elastic element 2 is disposed between the bottom end face of the button 1 and the bottom of the mounting cavity;

[0036] At least one movable pin 3 is provided on the peripheral wall of the button 1, which can move elastically along the radial direction of the button 1; a protrusion is provided in the middle of the mounting cavity, and a full-circle limiting groove 7 is provided on the outer periphery of the upper side of the protrusion; a first guide surface 8 is provided above the limiting groove 7, so that when the button 1 is pressed down, the movable pin 3 can be locked in the limiting groove 7, realizing the hiding of the button 1; the unlocking member 4 is movably sleeved on the limiting groove 7, which can move along the axial direction and is provided with a second guide surface 9; a third guide surface 10 is provided at the inner end of the movable pin 3, so that when the button 1 is pressed again and under the action of the first elastic member 2, the movable pin 3 can cross the limiting groove 7 to release the locking, thereby making the first limiting part on the button 1 locked on the second limiting part on the mounting cavity, so that part of the button 1 protrudes out of the panel 11.

[0037] The protrusion has a through hole 12 at its center; one end of the switch knob cutting piece 6 is movably mounted on the adapter 5, and the other end passes through the through hole 12; and the button 1 is always connected to the switch knob cutting piece 6 throughout its entire movement.

[0038] Specifically, in this embodiment, such as Figures 2 to 5 As shown, a radially penetrating mounting groove is provided on the peripheral wall of the button 1. A pressure ring 15 is screwed onto the outer side of the mounting groove, and the inner diameter of the pressure ring 15 is smaller than that of the mounting groove. The movable pin 3 is disposed in the mounting groove, and a limiting step 13 is provided on its peripheral wall, the outer diameter of which is larger than that of the inner diameter of the pressure ring 15. A second elastic element 14 is provided between the pressure ring 15 and the limiting step 13, which is spring-loaded onto the movable pin 3, with its two ends abutting against the inner end faces of the limiting step 13 and the pressure ring 15, respectively. A fixed pin 16 is connected to the outer end of the movable pin 3, the outer diameter of which is larger than that of the inner diameter of the pressure ring 15, so as to limit it to the outer end face of the first limiting element. Thus, under the action of the second elastic element 14, the inner end of the movable pin 3 is located in the cavity of the button 1 and can move elastically in the radial direction. The inner end of the movable pin 3 is provided with a third guide surface 10 that is adapted to the first guide surface 8, so that the movable pin 3 can move more smoothly along the radial direction of the button 1 and then enter the limiting groove 7.

[0039] The unlocking component 4 is sleeved on the limiting groove 7, and can move axially. It has a second guide surface 9 mirror-image of the first guide surface 8. When the movable pin 3 is engaged in the limiting groove 7, the button 1 is pressed again and further recessed under the action of the first elastic element 2. At this time, under the action of the third guide surface 10, the movable pin 3 overcomes the force of the second elastic element 14 and moves away from the axis of the button 1, thereby exiting the limiting groove 7 and abutting against the second guide surface 9. Then, under the force of the first elastic element 2, the button 1 pops out. At this time, the movable pin 3 drives the unlocking component 4 to move upward so that the second guide surface 9 and the first guide surface 8 are connected, thereby causing the movable pin 3 to disengage from the limiting groove 7 and unlock the button 1 until the first limiting part on the button 1 is engaged on the second limiting part on the mounting cavity. At this time, most of the button 1 protrudes outward.

[0040] In this embodiment, as Figure 2 , Figures 6 to 8 As shown, the seat includes a base 17 and an inner sleeve 18 connected to the base 17; the protrusion is located at the center of the base 17, with a boss 19 formed on its lower side and a limiting groove 7 provided on its upper side; a placement cavity 20 is provided on the lower end face of the boss 19; the upper end of the adapter 5 is sleeved in the placement cavity 20. The first elastic member 2 is a spring, which is sleeved on the boss 19, and the boss 19 provides guidance and limiting for the spring. A fixing sleeve 26 is also sleeved on the inner sleeve 18 to fix the inner sleeve 18 to the base 17.

[0041] In this embodiment, the switch knob cutting component 6 is provided with a limiting hole 21 on its axis; the button 1 is provided with a limiting post 22 that is adapted to the limiting hole 21 on its axis, so that the button 1 is always connected to the switch knob cutting component 6 during the entire movement stroke, so that the button 1 can directly rotate and adjust the switch knob cutting component 6 after the button 1 is released from the hidden state.

[0042] In this embodiment, the adapter 5 includes two protrusions 19 with a central mounting cavity. The lower protrusion 19 can be fitted onto the rotating flow regulating component of the valve core 27. The peripheral wall of the upper protrusion 19 is provided with a movable groove 23. One end of the switch knob cutting component 6 is provided with a movable part 24 that matches the movable groove 23. The movable part 24 can enter the movable groove 23 through the lower opening of the mounting cavity. Thus, during installation and use, it is only necessary to fit the adapter 5 onto the valve core 27 to complete the connection of the hidden button 1 mechanism to the valve core 27. The movable part 24 of the switch knob cutting component 6 can move axially within the movable groove 23 so that the button 1 can drive the switch knob cutting component 6 to move, thereby acting as a push switch for the valve core 27.

[0043] like Figure 2 As shown, button 1 is in a hidden state, with its outer end face flush with panel 11; at this time, the movable pin 3 is engaged with the limiting groove 7. Figure 10 As shown, the button 1 is in the unlocked state. At this time, the movable pin 3 is released from the engagement with the limiting groove 7, and the first limiting part on the button 1 is engaged with the second limiting part on the mounting cavity. At this time, most of the button 1 protrudes out of the panel 11.

[0044] This concealed button 1 mechanism is simple in structure and easy to install. Pressing button 1 opens and closes the valve core 27, while rotating button 1 adjusts the flow or temperature of the valve core 27. When button 1 is closed, the valve core 27 is concealed, with the outer surface of button 1 flush with the panel 11, resulting in a cleaner product appearance and meeting the needs of some products that require concealed switch knobs. It also prevents accidental adjustment of button 1, which could lead to excessive water flow or excessively high water temperature when the valve core 27 is opened.

[0045] This utility model also provides a shower, such as Figures 11 to 13 As shown, the device includes a valve body 25 and a valve core 27 disposed on the valve body 25; it also includes the concealed button mechanism, wherein the adapter 5 is connected to the rotating flow regulating component of the valve core 27, and can be axially limited by the pressure cap nut 28; the switch knob cutting component 6 acts as a push switch for the valve core 27; and a panel 11 disposed on the wall surface 29, the panel 11 having an opening adapted to the button 1. Alternatively, it may include a pre-embedded box 30 and a cover disposed on the pre-embedded box 30, the cover surrounding the concealed button 1 mechanism.

[0046] With the hidden button 1 mechanism, the button 1 is hidden when the shower is closed, making the panel 11 more concise; when the shower is turned on, the button 1 protrudes from the panel 11 and is in a rotatable and adjustable state, which can effectively avoid accidental adjustment of the button 1, which could lead to excessive water flow or excessive water temperature when the valve core 27 is opened.
