[0014] In some embodiments, the opposite surfaces of the support plates are respectively provided with hinged holes;

[0015] The opposite sides of the turnover member are provided with two hinged shafts;

[0016] The hinged shafts are respectively hinged in the hinged holes.

[0017] In some embodiments, the turnover member comprises a pressing plate and two pressing arms connected to the pressing plate, the two pressing arms are arranged at intervals, and the pressing plate forms a triggering portion.

[0018] The locking member comprises a locking member body and two locking arms, and the two locking arms are protruded on the two opposite side surfaces of the locking member body.

[0019] The two pressing arms are respectively in abutment with the sides of the two locking arms close to the stop member.

[0020] In some embodiments, the cavity wall of the mounting cavity is further provided with a limiting protrusion, the limiting protrusion is located on the side of the pressing plate away from the stop member, and when the locking member is in the locked position, the pressing plate is in abutment with the limiting protrusion.

[0021] In some embodiments, the locking end of the locking member is provided with a first inclined surface, and the end of the stop member is provided with a second inclined surface capable of being in inclined surface cooperation with the first inclined surface.

[0044] Referring to Figure 1 , Figure 2 , Figure 3 , according to some embodiments of the present application, the switch assembly 40 is used to movably arrange the water tank 30 on the body 10 of the household appliance 100, the body 10 is provided with a mounting groove 11, the opening of the mounting groove 11 is located on the side wall of the body 10, and the water tank 30 is accommodated in the mounting groove 11. The mounting cavity 31 is formed in the water tank 30.

[0045] The switch assembly 40 includes a stop piece 20, a locking piece 50 and a turnover piece 60. The stop piece 20 is arranged on the groove wall of the mounting groove 11. The locking piece 50 movably cooperates with the mounting cavity 31. The locking piece 50 has a locking position (as shown in Figure 2 ) which is in stop cooperation with the stop piece 20, and an unlocking position (as shown in Figure 5 ) which is out of stop cooperation with the stop piece 20. The turnover piece 60 is rotationally connected to the mounting cavity 31 and includes a trigger portion 61.

[0046] The trigger portion 61 can be flipped by an external operating end to a direction away from the first groove wall 111 to drive the locking piece 50 to the unlocking position. The first groove wall 111 is a groove wall of the mounting groove 11 for bearing the water tank 30.

[0047] The trigger portion 61 of the flipping piece 60 can be flipped by an external operating end to a direction away from the first groove wall 111 to drive the locking piece 50 to the unlocking position, so that the operating end, such as a hand, of an operator can operate the trigger portion 61 of the flipping piece 60 to unlock. Moreover, when the trigger portion 61 of the flipping piece 60 is flipped to a direction away from the first groove wall 111 (i.e., above the water tank 30), the locking piece 50 can be driven to the unlocking position, that is, the action direction of the unlocking operation of the switch assembly 40 is the same as the lifting direction of the water tank 30, so that the lifting action is performed synchronously during the unlocking operation, making the disassembly process of the water tank 30 simple and labor-saving, and greatly improving the user experience. Figure 2

[0048] Further, the outer wall of the water tank 30 is further provided with an operation port in communication with the mounting cavity 31, so that the external operating end can be inserted into the mounting cavity 31. In addition, the number of operation ports 32 is only one, so that the appearance of the household appliance is also more beautiful.

[0049] In the embodiment of the application, the water tank 30 is plugged and pulled with the first groove wall 111. Specifically, the bottom of the water tank 30 is provided with a water tank liquid passage 301, and the first groove wall 111 of the machine body 10 is provided with a machine body liquid passage 302. The water tank liquid passage 301 and the machine body liquid passage 302 can be plugged and pulled with a one-way valve. Since the pulling direction of the water tank 30 relative to the first groove wall 111 is the same as the flipping direction of the trigger portion 61 of the flipping piece 60 when the operator unlocks, the valve body of the one-way valve can be closed in a short time during the process that the water tank 30 is pulled out and lifted, which can reduce the water leakage phenomenon when the water tank liquid passage 301 and the machine body liquid passage 302 are separated from each other to a certain extent, and improve the user experience.

[0050] The locking piece 50 has a locking position for stop cooperation with the stop piece 20. When the locking piece 50 is in the locking position, the stop piece 20 can hinder the locking piece 50 from being separated from the mounting groove 11. For example, in the example shown in the drawings, the stop piece 20 is located outside the direction in which the locking piece 50 is separated from the mounting groove 11. In this way, since the locking piece 50 is blocked by the stop piece 20 and cannot be separated from the mounting groove 11, the water tank 30 also cannot be separated from the mounting groove 11. Figure 2 Further, when the locking piece 50 is in the locking position, part of the structure of the locking piece 50 needs to be extended out of the mounting cavity 31 and stop cooperated with the stop piece 20, so that the water tank 30 cannot be pulled out of the mounting groove 11 horizontally.

[0051] ​When the locking member 50 is in the unlocking position, the locking member 50 is disengaged from the stop member 20, and the stop member 20 no longer blocks the disengagement path of the locking member 50 from the mounting slot 11, so that the water tank 30 can be taken in and out of the mounting slot 11 through the slot opening of the mounting slot 11 from the side of the machine body 10.

[0052] In the embodiments of the present application, with reference to Figure 3 and Figure 4 , the switch assembly 40 further comprises an elastic reset member 70, which elastically abuts against the locking member 50, and the elastic reset member 70 has a tendency to switch the locking member 50 from the unlocking position to the locking position.

[0053] In this way, when the operator does not operate the turnover member 60, the locking member 50 can be switched from the unlocking position to the locking position under the action of the elastic reset member 70. And the locking member 50 is kept in the locking position, so that the switch assembly 40 is kept in the locked state for a long time.

[0054] In the embodiments of the present application, in combination with Figure 2 , Figure 4 , Figure 5 and Figure 6 , the mounting slot 11 can further comprise a second slot wall 112 arranged opposite to the first slot wall 111. The stop member 20 can be arranged on the second slot wall 112, and the water tank 30 is provided with a first opening 33 on the top wall facing the stop member 20 (i.e., facing the second slot wall 112), and the locking end of the locking member 50 extends out of the mounting cavity 31 from the first opening 33.

[0055] When the locking member 50 is in the locking position, the stop member 20 is arranged on the side of the locking member 50 close to the slot opening of the mounting slot 11.

[0056] The mounting cavity 31 is provided with a partition plate 34, and part of the structure of the locking member 50 is located between the partition plate 34 and the top wall of the water tank 30, and the two ends of the elastic reset member 70 are respectively pressed between the surfaces of the partition plate 34 and the locking member 50 opposite to each other.

[0057] In this way, one end of the elastic reset member 70 is pressed against the partition plate 34, and can apply an elastic force to the locking member 50 in a direction away from the partition plate 34, so that the locking end of the locking member 50 can always extend out of the first opening 33 and abut against the stop member 20 without external force.

[0058] The operation port 32 is arranged at a position between the partition plate 34 and the inner wall of the mounting cavity 31 close to the first slot wall 111. In the example shown in Figure 4 , the operation port 32 is arranged below the partition plate 34.

[0059] Further, with reference to Figure 5The elastic reset member 70 can be a spring. The surface of the locking member 50 facing the partition plate 34 is provided with a receiving groove 51, and the bottom of the receiving groove 51 is provided with a mounting column 511. One end of the elastic reset member 70 is sleeved on the mounting column 511 and located in the receiving groove 51.

[0060] In this way, the connection between the elastic reset member 70 and the locking member 50 is more reliable, and the elastic reset member 70 and the locking member 50 are prevented from being separated.

[0061] Further, in combination with Figure 5 and Figure 6 , the partition plate 34 is provided with an avoiding gap 341, and the opposite positions of the edge of the avoiding gap 341 are provided with two support plates 342. The two ends of the turnover member 60 are respectively hinged to the two support plates 342, so that the turnover member 60 can rotate in the avoiding gap 341. In this way, by providing the avoiding gap 341, the turnover member 60 can have a space for rotating action.

[0062] Further, in combination with Figure 6 and Figure 7 , the opposite surfaces of the support plates 342 are respectively provided with hinged holes 343. The opposite sides of the turnover member 60 are provided with two hinged shafts 344. The hinged shafts 344 are respectively hinged in the hinged holes 343. In this way, the turnover member 60 can be stably connected to the partition plate 34.

[0063] In some embodiments, in combination with Figure 5 and Figure 7 , the turnover member 60 includes a pressing plate 62 and two pressing arms 63 connected to the pressing plate 62. The two pressing arms 63 are spaced apart, and the pressing plate 62 forms the trigger part 61.

[0064] The locking member 50 includes a locking member body 52 and two locking arms 53. The two locking arms 53 are protruded from the two opposite side surfaces of the locking member body 52. The two pressing arms 63 respectively press the two locking arms 53 on the side close to the stop member 20.

[0065] In this way, when the pressing plate 62 of the turnover member 60 is turned in the pulling-out direction, the two pressing arms 63 can press the locking arms 53 to move away from the stop member 20 to the unlocking position. When the pressing plate 62 is not subjected to force, the locking member 50 can be returned to the locking position under the action of the elastic reset member 70.

[0066] Further, in combination with Figure 6The mounting cavity 31 also has a limiting protrusion 311 on its cavity wall. The limiting protrusion 311 is located on the side of the pressure plate 62 away from the stop member 20. When the locking member 50 is in the locked position, the pressure plate 62 abuts against the limiting protrusion 311. In this way, when the pressure arm 63 presses against the locking arm 53, the pressure plate 62 cannot continue to rotate in the opposite direction to the pull-out direction, thus preventing the locking member 50 from completely disengaging from the mounting cavity 31 through the first opening 33. That is, the limiting protrusion 311 is at the maximum stroke position when the pressure plate 62 rotates clockwise.

[0067] Furthermore, the locking end of the locking member 50 is provided with a first inclined surface 501, and the end of the stop member 20 is provided with a second inclined surface 201 that can engage with the first inclined surface 501. The first inclined surface 501 and the second inclined surface 201 are arranged in parallel.

[0068] With this configuration, when the water tank 30 enters the mounting groove 11, the inclined surfaces of the first inclined surface 501 and the second inclined surface 201 work together to facilitate the retraction of the locking member 50 into the mounting cavity 31, thus avoiding any impact or obstruction on the operation of the water tank 30 entering the mounting groove 11.

[0069] In this embodiment of the application, combined with Figure 1 and Figure 8 The water tank 30 includes a water tank body 35 and a water tank cover 36. The water tank cover 36 is placed on the water tank body 35, and the mounting cavity 31 is located in the water tank cover 36. This arrangement facilitates the installation of the switch assembly 40 into the water tank cover 36.

[0070] Reference Figure 1 This application also provides a household appliance 100, which can be a cooling fan or other electrical appliances that require a water tank. The household appliance 100 may include the aforementioned switch assembly 40, body 10, and water tank 30.

[0071] The following is combined Figures 1-8 This paper describes the operation of the switch assembly 40 in the household appliance 100.

[0072] In the switch assembly 40 of this application, unlocking is achieved by lifting the flip-up member 60 upwards. Specifically, the pressure plate 62 of the flip-up member 60 can be lifted upwards by hand, causing the pressure plate 62 to rotate around the lifting direction of the water tank 30 (counterclockwise in the figure). This causes the pressure arm 63 to press down on the locking arm 53 of the locking member 50. The locking arm 53 overcomes the elastic force of the elastic reset member 70, moving the locking member body 52 downwards, placing the locking member 50 in the unlocked position and releasing its stop engagement with the stop member 20. At this point, the water tank 30 can be lifted out by hand. In this process, not only is the switch assembly 40 unlocked, but the water tank 30 can also be lifted out directly. This process is short and will not cause water leakage from the water tank 30 due to pressing.

[0073] In this process, to unlock the switch assembly 40, just lift the pressure plate 62 upward, when the pressure plate 62 rotates around the shaft, the resistance is mainly the elastic force of the elastic return member 70. The operation is simple and convenient.

[0074] When returning to the water tank 30, it only needs to press the water tank 30 into the mounting groove 11. Specifically, the first inclined surface 501 of the locking member 50 is inclinedly matched with the second inclined surface 201 on the stop member 20, during the process of pushing the water tank 30 into the mounting groove 11, the locking member 50 gradually moves to the direction of retracting the mounting cavity under the pressing action of the stop member 20, until the water tank 30 completely enters the mounting groove 11, the locking member 50 returns to the locking position under the elastic force of the elastic return member 70, so that the water tank 30 is positioned in the mounting groove 11.

[0075] The technical features of the above-described embodiments can be combined arbitrarily, in order to make the description simple, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0076] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
