[0049] Figure 1 is a schematic structural diagram of a key dialing device according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 4 The embodiment of the utility model provides a dial key device for an air conditioner, comprising a support base 100, a dial key 200 and a pot piece 300. The dial key 200 is rotatably mounted on the support base 100 through a rotating shaft. The pot piece 300 is configured to receive the pressing of the dial key 200 when the dial key 200 rotates to one side.

[0050] The pot piece 300 can be fixedly arranged on the circuit board, with the convex surface of the pot piece 300 facing the dial key 200. When the dial key 200 rotates to one side, it can directly or indirectly press on the convex surface of the pot piece 300. The pot piece 300 is squeezed and deformed to contact the circuit, so that the circuit receives the signal and the circuit state changes.

[0051] In this embodiment, the circuit state can be controlled by moving the dial key 200 to a specified position. The dial key 200 squeezes the pot piece 300 during its rotation along the shaft. The pot piece 300 is deformed and contacts the circuit, so that the circuit is connected. Since the pot piece 300 makes a sound when it is deformed and the circuit is connected, the user can get feedback from the auditory sense that the dial key 200 is in place, which improves the user's experience of moving the dial key 200. Moreover, since the resistance generated by the pot piece 300 during the process of being pressed and deformed is different, moving the dial key 200 will produce a sense of paragraph, and the user can get feedback from the tactile sense that the dial key 200 is in place, which further improves the user's experience of moving the dial key 200.

[0052] In some embodiments of the key dialing device of the present invention, Figure 2 or Figure 4 As shown, the key-dial device further includes a button 400 , which is disposed between the pot piece 300 and the key 200 to transmit the pressing of the key 200 to the pot piece 300 .

[0053] In this embodiment, the dial key 200 rotates along the rotating shaft, and during the rotation, the button 400 is pressed, and the button 400 is recessed toward the pot piece 300. The pot piece 300 is squeezed and deformed to contact the circuit, so that the circuit receives a signal and the circuit state changes. The pot piece 300 is not directly squeezed by the dial key 200, which avoids the pot piece 300 from being worn or even damaged, thereby increasing the service life of the pot piece 300.

[0054] Preferably, in some embodiments of the key dialing device of the present invention, the key 400 is an elastic key with a self-resetting function.

[0055] In this embodiment, the elastic button can automatically reset to the shape before being pressed, avoiding long-term squeezing of the pot piece 300, so that the circuit state can be quickly changed by toggling the key 200.

[0056] Further, in some embodiments of the key dialing device of the present utility model, as Figures 1 to 4 As shown, the key-dial device further includes a key box 510 and a key board 520 , wherein the key board 520 is disposed in the key box 510 , and the support base 100 is mounted on the key box 510 or the key board 520 . The pot piece 300 is disposed on the key board 520 .

[0057] In this embodiment, the key box 510 protects the key 400, preventing the key 400 from being damaged due to collision. In addition, the design of the key box 510 makes the arrangement of other components in the key dialing device more neat, making the key dialing device more beautiful.

[0058] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, there are two buttons 400 and two pot pieces 300, and the two pot pieces 300 are arranged on both sides of the dial key 200, so that one pot piece 300 receives the pressure of the dial key 200 when the dial key 200 rotates to one side, and the other pot piece 300 receives the pressure of the dial key 200 when the dial key 200 rotates to the other side.

[0059] In this embodiment, the dial key 200 rotates along the axis to both sides, so that the pot pieces 300 on both sides can be squeezed to deform and contact the circuit, so that the circuit receives different signals and then adjusts the circuit to the desired circuit state.

[0060] In some embodiments of the key dialing device of the present invention, Figure 4 As shown, the key-dial device further includes a key base 410 , on which two keys 400 are disposed. The key base 410 and the two keys 400 are integrally formed, and the key base 410 and the two keys 400 are both made of rubber.

[0061] In this embodiment, the key base 410 and the two keys 400 are integrally formed, so that the keys 400 are more firmly fixed, and the keys 400 are prevented from sliding, thereby preventing the keys 400 from being squeezed due to the displacement of the keys 400, and reducing the failure rate of the key-push device. The rubber material has low cost, good elasticity, and self-reset capability.

[0062] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, the support base 100 has a bottom frame 110, and a through hole 111 is arranged on the bottom frame 110. The pot piece 300 is arranged on one side of the bottom frame 110, and the pot piece 300 is arranged corresponding to the through hole 111. The dial key 200 is arranged on the other side of the bottom frame 110.

[0063] In some embodiments of the key dialing device of the present invention, Figure 2As shown, the dial key 200 includes an extrusion block 210 , and the two side surfaces of the extrusion block 210 are concave and convex respectively, so that the extrusion block 210 is curved, with the concave surface facing the bottom frame 110 , and the extrusion block 210 passes through the through hole 111 to press the pot piece 300 .

[0064] In this embodiment, the perforation 111 serves as a limit for the extrusion block 210 when it is extruded toward the pot piece 300, thereby preventing the extrusion block 210 from being offset when the key 200 is turned, and failing to squeeze the pot piece 300, causing the key device to fail to work properly.

[0065] In other embodiments of the key dialing device of the present invention, Figure 2 or Figure 4 As shown, a pressure rod 800 is provided between the dial key 200 and the pot piece 300 , and the pressure rod 800 passes through the through hole 111 , and the pressure rod 800 transmits the pressing of the dial key 200 to the pot piece 300 .

[0066] In this embodiment, the perforation 111 serves to limit the pressure rod 800 when it is pressed toward the pot piece 300, thereby preventing the pressure rod 800 from being offset when the key 200 is turned to cause the pressure rod 800 to move, thereby failing to press the pot piece 300 and causing the key device to fail to work properly.

[0067] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, the dial key 200 includes a pressing block 210 for pressing the pot piece 300, and the two side surfaces of the pressing block 210 are respectively concave and convex, so that the pressing block 210 is curved. The rotating shaft is located on the side of the pressing block 210 with the concave surface.

[0068] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, the key-shifting device further includes a push rod 610 and a reset device 620. The push rod 610 is movably mounted on the support seat 100 along its length direction, and a support head is provided at the end of the push rod 610 facing the concave surface. A plurality of collision grooves 221 cooperating with the support head are provided on the concave surface, and the plurality of collision grooves 221 are sequentially arranged at intervals along the circumferential direction of the rotation axis of the key 200, and the moving direction of the support head is perpendicular to the rotation axis of the key 200. The reset device 620 causes the support head to move toward the concave surface through the push rod 610.

[0069] In this embodiment, during the process of turning the dial key 200, the support head is squeezed by the groove wall of the collision groove 221, and moves along the length direction of the top rod 610 following the multiple collision grooves 221. The groove wall of the reset device 620 and the collision groove 221 cause the multiple collision grooves 221 to collide and contact with the support head multiple times, so as to produce a sense of paragraph when the dial key 200 is turned, thereby improving the user's experience of turning the dial key 200.

[0070] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, the concave surface may also be provided with a positioning groove 222 that cooperates with the support head, and in the moving direction of the support head toward the dial key 200, the rotation axis of the dial key 200 and the positioning groove 222 are sequentially arranged. The reset device 620 causes the support head to be inserted into the positioning groove 222 through the push rod 610.

[0071] In this embodiment, the positioning groove 222 is disposed at the middle position of the concave surface, so that when the support head is inserted into the positioning groove 222, the dial key 200 is reset to the normal state.

[0072] Furthermore, in some embodiments of the key-dial device of the present invention, when the collision groove 221 is disposed at the middle position of the concave surface, it may also be referred to as a positioning groove 222 .

[0073] Alternatively, in some alternative embodiments of the key-dial device of the present invention, the collision groove 221 is disposed on both sides of the middle position of the concave surface.

[0074] In some embodiments of the key dialing device of the present invention, Figure 1 or Figure 4 As shown, the dial key 200 further includes a dial block 240 and two end plates 230. The dial block 240 is disposed on the convex surface of the extrusion block 210. The two end plates 230 are respectively disposed at both ends of the extrusion block 210. The end plates 230 are rotatably mounted on the support seat 100 through a rotating shaft.

[0075] In this embodiment, the end plate 230 can be an integral structure with the rotating shaft. The design of the end plate 230 can improve the strength of the dial key 200, making it less likely to be damaged or broken. Moreover, the rotational connection between the end plate 230 and the support base 100 makes the connection between the dial key 200 and the support base 100 more secure, reducing the possibility of the dial key 200 falling off.

[0076] In some embodiments of the key dialing device of the present invention, Figure 3As shown, the dial key device also includes a torsion spring 700. The torsion spring 700 includes a spring coil portion 710 and two arms 720 connected to the spring coil portion 710, and the spring coil portion 710 is sleeved on the rotating shaft. The two arms 720 are arranged on both sides of the spring coil portion 710, and each arm 720 has a first action position 731 and a second action position 732, and the first action position 731 is between the second action position 732 and the spring coil portion 710. The first action position 731 contacts the dial key 200, and the second action position 732 contacts the support seat 100. The two first action positions 731 and the two second action positions 732 are located on the same side of the corresponding contact positions on the dial key 200 and the support seat 100, so that when the dial key 200 is dialed to one side of the dial key 200, one of the two arms 720 acts on the support seat 100, and the other acts on the dial key 200, so that the torsion spring 700 accumulates force, thereby prompting the dial key 200 to reset.

[0077] In this embodiment, when the dial key 200 is moved sideways, the torsion spring 700 generates a force to urge the dial key 200 to reset, so that the dial key 200 automatically resets, reducing the user's operation and improving the user's experience. The structure of supporting the torsion spring 700 by the support base 100 and using the torsion spring 700 to store force to support the dial key 200 to reset is simple, easy to manufacture and install, and reduces production costs.

[0078] The embodiment of the utility model further provides an air conditioner. In some embodiments of the air conditioner of the utility model, the air conditioner comprises the key dial device in any of the above embodiments.

[0079] In this embodiment, the circuit state can be controlled by moving the dial key 200 to a specified position. The dial key 200 squeezes the pot piece 300 during its rotation along the shaft. The pot piece 300 is deformed and contacts the circuit, so that the circuit is connected. Since the pot piece 300 makes a sound when it is deformed and the circuit is connected, the user can get feedback from the auditory sense that the dial key 200 is in place, which improves the user's experience of moving the dial key 200. Moreover, since the resistance generated by the pot piece 300 during the process of being pressed and deformed is different, moving the dial key will produce a sense of paragraph, and the user can get feedback from the tactile sense that the dial key is in place, which further improves the user's experience of moving the dial key 200.

[0080] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
