[0020] The utility model will be further detailed with the embodiment given below in conjunction with the drawings.

[0021] Refer to Figures 1-5 The utility model discloses a multiple drive mechanism of shower heater switch, including base 1, install in base 1 for swing switch state's switching piece 2, install on the base 1 panel 3, a plurality of install on the panel 3 button 4, button 4 passes through swing cooperation switching piece 2 and switches the state, and the position of button 4 corresponding switching piece 2 is provided with the protruding contact 5 of piece 5;Switching piece 2 is provided with the jack 21, and button 4 is also provided with the pin 41, when the panel 3 is installed on the base 1, the pin 41 is inserted in the jack 21, and cooperation is formed in the swing direction of button 4 and switch, when button 4 is pressed and swings, button 4 and switching piece 2 form linkage through contact 5 and / or form linkage through the cooperation of pin 41 and jack 21.

[0022] In actual assembly, the base 1 is fixed in the wall body secret box through screw, the panel 3 can be fixed above the base 1 through the buckling structure or additional connecting piece, the button 4 is installed in the preset position of the panel 3 through the adaptive structure (such as the connecting pin 31 in the subsequent scheme) of the panel 3, to ensure that the button 4 can stably swing around the preset axis. When the user presses the button 4, the button 4 rotates downward around the swing axis, at this time, the contact 5 on the button 4 will first contact and apply pressure to the surface of the switching piece 2, and then drive the switching piece 2 to swing to realize the switching of the switch state; at the same time, since the pin 41 has been previously inserted into the jack 21 of the switching piece 2, and the pin 41 and the jack 21 have a cooperation relationship in the swing direction, the button 4 will push or pull the inner wall of the jack 21 during the swing process, further assisting the swing of the switching piece 2. Even if the base 1 is screwed too tightly, causing the panel 3 to slightly rise at both ends, causing a slight shift in the relative position of the button 4 and the switching piece 2, the double linkage structure formed by the contact 5 and the pin 41 can still ensure that at least one linkage mode is effective, thereby improving the problem that the button 4 is suspended and cannot be accurately switched, and improving the stability of the switch switching.

[0023] In order to facilitate the balance of the linkage between the key 4 and the switching piece 2 during the swing process, in an alternative scheme, the position corresponding to the key 4 on the panel 3 is provided with a connecting pin 31 for the swing connection of the key 4, the plug 41 on the key 4 has at least two and is located on both sides of the connecting pin 31 corresponding to the swing direction of the key 4; The position and number of the plug hole 21 correspond to the plug 41.

[0024] The connecting pin 31 can be fixed in the position corresponding to the key 4 on the inner side of the panel 3 by injection molding or welding process, and the position corresponding to the connecting pin 31 on the key 4 is provided with a hole or slot structure matched with the connecting pin 31, and the key 4 can swing freely around the connecting pin 31. Two plugs 41 are distributed on both sides of the connecting pin 31, for example, when the key 4 swings clockwise around the connecting pin 31, the plug 41 on one side will push the inner wall of the plug hole 21, and the plug 41 on the other side will pull the inner wall of the plug hole 21. This symmetrical distribution structure can make the driving force of the switching piece 2 more balanced, and avoid the jamming of the switching piece 2 or the damage of the components due to the excessive force on one side.

[0025] In order to simplify the assembly process of the plug 41 and the plug hole 21 and reduce the assembly difficulty, the following further optimization can be selected: one side of the plug hole 21 is a bevel, and the plug hole 21 is flared through the bevel, and the plug 41 is guided by the bevel.

[0026] The flared structure of the plug hole 21 faces the direction of the plug 41 insertion, when the panel 3 is installed by buckling the base 1, the plug 41 will first contact the bevel of the plug hole 21, and with the further fitting of the panel 3 and the base 1, the bevel will guide the plug 41 to smoothly slide into the plug hole 21, effectively improving the assembly efficiency. At the same time, the setting of the bevel can also avoid the hard collision between the plug 41 and the edge of the plug hole 21 during the insertion, reduce the damage risk of the plug 41 or the switching piece 2, and prolong the service life of the components.

[0027] In some options, in order to avoid the mutual interference of the two plugs 41 during the insertion process and ensure smooth assembly, the position of the bevel of the plug hole 21 can be limited: the bevel is located on the side where the two plug holes 21 are away from each other.

[0028] When the bevels of the two plug holes 21 face away from each other, the two plugs 41 will be guided along the bevels of their respective plug holes 21 during the insertion process, further optimizing the force balance of the switching piece 2.

[0029] In order to improve the fastening of the plug 41 after being matched with the socket 21, and avoid the plug 41 from falling off from the socket 21 during use, in an alternative embodiment: the two plugs 41 are matched with the inner wall of the socket 21 by clamping after being inserted into the corresponding socket 21; and / or, the plug 41 is matched with the inner wall of the socket 21 by outwardly pressing after being inserted into the corresponding socket 21.

[0030] If the clamping matching mode is adopted, the two plugs 41 can be abutted on the inner wall of the corresponding socket 21 to form a clamping action after being inserted into the corresponding socket 21, and vice versa, the two plugs 41 can be outwardly pressed to form a matching action. The two matching modes can be used alone or simultaneously, which can effectively improve the connection stability of the plug 41 and the socket 21, reduce the situation that the plug 41 is loose or falls off due to vibration or frequent pressing, and ensure the long-term effectiveness of the linkage structure.

[0031] In order to enable the plug 41 and the socket 21 to automatically form reliable pressing or clamping matching, the following structure can also be adopted: a guide protrusion 6 is arranged on one side of the inner wall of the socket 21 and close to the bottom of the socket 21, and the plug 41 is abutted on the guide protrusion 6 after being inserted into the socket 21 and continues to be inserted, and the guide protrusion 6 guides the plug 41 to abut on the inner wall of the socket 21 away from the guide protrusion 6.

[0032] The guide protrusion 6 can be integrally formed with the switching piece 2 by an injection molding process, and the cross section thereof can be arc-shaped, wedge-shaped or trapezoidal, so as to avoid scratching the surface of the plug 41 during the insertion of the plug 41. When the plug 41 is inserted into the socket 21, it will first slide down along the inner wall of the socket 21, and when the front end of the plug 41 contacts the guide protrusion 6, the guide protrusion 6 will generate a pushing force on the plug 41 to one side during the process of continuing to be inserted, so as to force the plug 41 to move closer to the inner wall of the socket 21 away from the guide protrusion 6 and abut tightly. This structure can automatically press by using the action of inserting the plug 41, without the need for additional elastic structure, which simplifies the component design and assembly process, and also ensures that the plug 41 and the inner wall of the socket 21 always remain in abutment, thereby improving the reliability of the linkage.

[0033] In order to reasonably arrange multiple adjacent keys 4 in the limited space of the panel 3 and avoid interference between the keys 4, in a feasible scheme: a buckle 42 is arranged on the key 4 corresponding to the position of the connecting pin 31, and the key 4 is connected with the connecting pin 31 through the buckle 42, and the key 4 is rotatably connected with the buckle 42; among the two adjacent keys 4, the lower part of one key 4 extends towards the lower part of the other key 4 and is provided with a transition piece 43, and the plug 41 of the key 4 is located on the transition piece 43, and the transition piece 43 is provided with a through hole for the buckle 42 of the key 4 above to pass out and be connected with the corresponding connecting pin 31.

[0034] The buckle 42 is integrally formed with the key 4, and an arc-shaped slot adapted to the connecting pin 31 is formed in the inner side of the buckle 42, so that the buckle 42 can flexibly rotate around the connecting pin 31, thereby realizing the swing function of the key 4. For the two adjacent keys 4, the transition piece 43 extending from the lower key 4 can cover part of the bottom area of the upper key 4, and the through hole on the transition piece 43 is accurately positioned corresponding to the buckle 42 of the upper key 4, so as to ensure that the buckle 42 of the upper key 4 can pass through the through hole and be clamped with the connecting pin 31 on the panel 3, avoiding the installation of the buckle 42 being blocked by the transition piece 43. At the same time, the pin 41 is arranged on the transition piece 43, so that the position of the pin 41 is closer to the switching piece 2, and the linkage distance is shortened. This structure can effectively utilize the space below the panel 3, realize the compact arrangement of multiple keys 4, and avoid mutual interference when the keys 4 swing.

[0035] In order to avoid friction or collision between the upper key 4 and the transition piece 43 of the lower key 4 when the upper key 4 swings, affecting the smoothness of the key 4 swing, the transition piece 43 can be optimized as follows: a triangular protrusion 44 is arranged on the transition piece 43 corresponding to the upper key 4, and the triangular protrusion 44 provides a swing avoidance space for the key 4.

[0036] The triangular protrusion 44 is integrally formed with the transition piece 43, and the part missing from the triangular protrusion 44 compared with the rectangle can form an avoidance space to make the key 4 swing smoothly.

[0037] In order to further improve the stability of the upper key 4 when it swings, avoid the key 4 from being deviated due to too large swing amplitude or uneven force, in some embodiments: the tip of the triangular protrusion 44 abuts against the upper key 4, so as to support the swing of the key 4.

[0038] The tip of the triangular protrusion 44 is treated with smoothness, and keeps a slight abutting state with the bottom of the upper key 4. When the upper key 4 is not pressed, the support of the triangular protrusion 44 can make the key 4 stably keep in the initial position, avoiding the key 4 from sagging due to gravity or external vibration; when the key 4 is pressed and swings, the tip of the triangular protrusion 44 will slide and support with the swing of the key 4, providing a stable support point for the key 4, reducing the shaking or deviation of the key 4 in the swing process, ensuring that the contact piece 5 and the pin 41 on the key 4 can accurately cooperate with the switching piece 2, and further improving the accuracy and stability of the linkage.

[0039] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall be within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as the protection scope of the present application.
