In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0029] Combine the following Figures 1 to 6 The invention describes the switch assembly, water tank, specific hooks and working process of the air conditioner.

[0030] An embodiment of the utility model provides a switch assembly, combined with Figure 1 and Figure 2 As shown, it includes a component base 1, a handle base 2, a top block 3 and a claw 4, wherein the handle base 2 is rotatably connected to the component base 1 through a first rotating axis; the top block 3 is fixedly connected to one end of the handle base 2; the claw 4 is rotatably connected to the component base 1 through a second rotating axis, and one side of the claw 4 is in contact with the top block 3 so that the claw 4 can be rotated around the second rotating axis through the pushing of the top block 3.

[0031] It can be understood that the switch assembly of this embodiment, through the rotation of the claw 4, makes the claw 4 lock or unlock the locked member to achieve the function of the switch. Figure 1 As shown, the assembly base 1 is a vertical plate base, and the handle base 2 is rotatably connected to one side of the assembly base 1 through a first rotating axis. The handle base 2 forms an L-shaped structure. After one end of the handle base 2 is turned and rotated, the other end will inevitably drive the top block 3 to rotate around the first rotating axis. The bottom end of the top block 3 contacts the claw 4. As the handle base 2 rotates, the top block 3 will form a squeezing and pushing effect on the claw 4. Since the claw 4 is rotatably connected to the assembly base 1 through a second rotating axis, as the top block 3 squeezes and pushes the claw 4, the claw 4 rotates around the second rotating axis. During the rotation of the claw 4, its lower end can lock or unlock the locked part (for details, please refer to the locking or unlocking of the water tank later). This embodiment has a simple structure, and the locked part can be locked or unlocked by the successive rotation of the two components, and the operation is simple. The switch assembly of this embodiment is applied to the air-conditioning water tank structure, so that the air-conditioning water tank is not easily opened by external force during the operation of the air-conditioning, thereby ensuring the normal operation of the air-conditioning water tank.

[0032] In some embodiments of the switch assembly of the present utility model, the switch assembly further includes a safety device. Continuing to refer to Figure 1 As shown, the safety device includes a limit crossbar 5 and a handle base 6. The limit crossbar 5 and the handle base 2 are synchronously installed on the first rotating shaft; the handle base 6 is rotatably inserted through the assembly base 1. The handle base 6 is located below one end of the limit crossbar 5, and the handle base 6 is provided with a limit card slot adapted to the end of the limit crossbar 5.

[0033] It can be understood that in this embodiment, the limit crossbar 5 and the handle base 2 can rotate synchronously around the first rotating shaft, and the end of the limit crossbar 5 can cooperate with the limit card slot on the handle base 6 for limit. During the use of the switch assembly, first rotate the handle base 6 on the assembly base 1 to disengage the limit card slot on the handle base 6 from the limit crossbar 5, and then the limit crossbar 5 and the handle base 2 can be rotated. When the handle base 2 rotates to make the claw 4 reach the required locked or unlocked state, rotate the handle base 6 again to make the limit card slot of the handle base 6 cooperate with the end of the limit crossbar 5 for limit. At this time, the limit crossbar 5 and the handle base 2 cannot continue to rotate, and the locked or unlocked state at this time is maintained. When it is necessary to change the state at this time, disengage the limit card slot on the handle base 6 from the limit crossbar 5 again, and the operation can be performed again. It should be understood that during the switching process of the locked and unlocked states in this embodiment, the rotation angles of the limit crossbar 5 and the handle base 2 are very small to achieve the state change of the claw 4. Therefore, during the rotation of the handle base 6, the limit card slot can always be in a state where it can cooperate with the limit crossbar 5. Through the cooperation of the limit card slot on the handle base 6 and the limit crossbar 5, the switch assembly of this embodiment has the effect of state locking and is not easily switched between the locked and unlocked states due to accidental touch.

[0034] In some other embodiments of the switch assembly of the present utility model, referring to Figure 4 As shown, a spring chamber is provided on the side of the assembly base 1 facing away from the handle base 2, and a spring telescopic column 7 is provided in the spring chamber; as shown in Figure 5, a plurality of grooves 8 are circumferentially provided at the end of the handle base 6; the end of the spring telescopic column 7 is located in the groove 8 in the extended state and leaves the groove 8 in the compressed state.

[0035] It can be understood that a through hole is provided on the component base 1, the handle base 6 is inserted through the through hole, and a plurality of grooves 8 on the circumferential direction of the end of the handle base 6 are located in the through hole. A spring chamber provided on one side of the back of the component base 1 is communicated with the through hole. A spring telescopic column 7 is provided in the spring chamber. The spring telescopic column 7 can be extended and compressed. As the handle base 6 rotates, when the end of the spring telescopic column 7 faces one of the grooves 8, the spring telescopic column 7 extends and enters the groove 8. Continuing to rotate the handle base 6, the spring telescopic column 7 disengages from the groove 8 and presents a compressed state until it rotates to the next groove 8. Through the structure of this embodiment, a multi-level tactile sensation is presented during the rotation of the handle base 6. When the handle base 6 rotates to the required angle, the spring telescopic column 7 in this state extends and cooperates with the corresponding groove 8 for fixation. If no external force is applied, this state will be maintained and the handle base 6 will not rotate randomly, further forming an additional safeguard for the locked and unlocked states of the switch component.

[0036] Further, in some examples, in combination with Figure 4 and Figure 5 as shown, the inner wall of the groove 8 is set as a smooth transition arc surface towards the opening; the spring telescopic column 7 includes a compression spring and a safety column. The first end of the compression spring is fixed in the spring chamber, the second end of the compression spring is in contact with the first end of the safety column, and the second end of the safety column is provided with a spherical end head to be able to slide on the smooth transition arc surface of the groove 8. It can be understood that the structures of the spring telescopic column 7 and the groove 8 in this example achieve the compression and extension of the safety column relative to the groove 8 through the compression and extension of the compression spring, and the transition switching between adjacent two grooves 8 of the spring telescopic column 7 is achieved by the sliding of the spherical end head at the end of the safety column on the smooth transition arc surface of the groove 8.

[0037] In other examples, an indicating protrusion 9 is provided on one end face of the handle base 6. It can be understood that the indicating protrusion 9 can display the rotation angle of the handle base 6. After the switch component reaches the locked or unlocked state, note the position corresponding to the indicating protrusion 9. If the safety device malfunctions and the handle base 6 rotates, the position corresponding to the indicating protrusion 9 will change, reminding the operator of the abnormality of the safety device. At this time, attention should be paid to whether the state of the switch component is abnormal.

[0038] Based on the above several embodiments, in the structure of the switch component of this embodiment, referring to Figure 3 as shown, the end of the top block 3 is an arc surface structure, and an arc-shaped protrusion block 10 is provided on one side of the claw 4. The arc-shaped protrusion block 10 is in smooth contact with the arc surface structure at the end of the top block 3.

[0039] It can be understood that the locking and unlocking of the switch assembly of the present utility model are mainly achieved by the rotation of the claw 4. Since the top block 3 rotates with the handle base 2, the movement track of the contact part between the top block 3 and the claw 4 is an arc. In this embodiment, the end of the top block 3 is set as an arc surface structure, and an arc-shaped raised block 10 is arranged on one side of the claw 4. Then, as the top block 3 rotates, the contact position changes continuously, and the top block 3 will always form a line contact with the arc-shaped raised block 10 of the claw 4, compensating for the displacement change in the linear direction caused by the rotation angle change of the top block 3, so that the claw 4 can rotate smoothly and continuously.

[0040] Further, in some examples, a return spring 11 is connected to the side of the claw 4 away from the arc-shaped raised block 10, and one end of the return spring 11 is fixedly connected to the assembly base 1. Referring again to Figure 3 As shown, it can be understood that when the handle base 2 is rotated clockwise, the handle base 2 drives the top block 3 to rotate clockwise. The top block 3 continuously pushes the arc-shaped raised block 10 of the claw 4, causing the claw 4 to rotate counterclockwise. The return spring 11 is compressed. The protruding part at the bottom of the claw 4 is used to achieve locking. As the claw 4 rotates counterclockwise, the protruding part at the bottom of the claw 4 rises from the locking position and disengages from the locked part. At this time, the switch assembly is unlocked; when locking is required again, the handle base 2 is rotated counterclockwise. The handle base 2 drives the top block 3 to rotate counterclockwise. The top block 3 disengages from the arc-shaped raised block 10. At this time, the return spring 11 is no longer stressed, and the compressed return spring 11 automatically resets, pushing the claw 4 to rotate clockwise. The protruding part at the bottom of the claw 4 descends to the locking position to lock the locked part.

[0041] On the other hand, the present utility model also provides a water tank. Referring to Figure 6 As shown, it includes a water tank accommodation bin 12 and a water tank body 13 movably arranged in the water tank accommodation bin 12. The water tank accommodation bin 12 and the water tank body 13 are connected by the switch assembly of any one of the above embodiments to achieve locking or unlocking between the water tank accommodation bin 12 and the water tank body 13.

[0042] In some specific embodiments of the water tank of the present utility model, referring again to Figure 6 As shown, a switch movement groove 14 is arranged on the water tank accommodation bin 12, and a lock port is arranged on the water tank body 13; the switch assembly is fixed to the inner wall of the water tank accommodation bin 12. The switch assembly is connected with a handle for controlling the locking and unlocking of the switch assembly. The handle passes through the switch movement groove 14. The claw 4 of the switch assembly is adapted to enter or exit the lock port on the water tank body 13 to achieve locking or unlocking between the water tank accommodation bin 12 and the water tank body 13.

[0043] It can be understood that for the water tank in this embodiment, a pull-out water tank structure is formed by the water tank accommodation bin 12 and the water tank body 13. The pulling of the water tank body 13 in the water tank accommodation bin 12 is locked and unlocked through the switch assembly. The assembly base 1 of the switch assembly is fixed to the inner wall of the water tank accommodation bin 12. When the claw 4 of the switch assembly is stuck in the locking opening on the water tank body 13, the water tank accommodation bin 12 and the water tank body 13 are locked to each other. When the claw 4 of the switch assembly disengages from the locking opening on the water tank body 13, the water tank accommodation bin 12 and the water tank body 13 are unlocked. Two arc-shaped switch movement grooves 14 are provided on the water tank accommodation bin 12. The switch movement grooves 14 are used for passing through the handle that controls the switch assembly to lock and unlock. In some examples, the handle includes a handle and a turning handle. Among them, the turning handle is connected to the turning handle base 2 and is used to control the rotation of the turning handle base 2 to lock or unlock. The handle is connected to the handle base 6 and is used to control the handle base 6 to maintain the locked or unlocked state. Through the water tank structure of this embodiment, the effective locking and unlocking of the pull-out water tank formed by the water tank accommodation bin 12 and the water tank body 13 are realized, avoiding the pull-out water tank being opened by external force during operation and ensuring the normal operation of the water tank.

[0044] On the other hand, the present utility model also provides an air conditioner, which includes the above-mentioned water tank. It can be understood that since the air conditioner provided in this embodiment includes the above-mentioned water tank structure, it also has all the functions of the above-mentioned water tank structure. During the operation of the air conditioner, the water tank of the air conditioner is not easily opened by external force misoperation, ensuring the normal operation of the air conditioner.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
