[0046] See also Figure 1 , an embodiment of the present invention provides a panel assembly structure 100, which is used for an electrical appliance, and the panel 20 of the panel assembly structure 100 includes an operating part 21, and the operating part 21 can be a key structure or a touchable display window structure, and the corresponding position of the PCB board (circuit board 32) is triggered by operating the operating part 21, that is, the PCB board receives the signal transmitted to it by the operating part 21 of the panel 20, so as to control the electrical appliance to perform a corresponding action. Specifically, the above-mentioned electrical appliance is a humidifier, and it can be understood that in other embodiments, the type of electrical appliance is not limited, that is, any electrical appliance that needs to be provided with the panel assembly structure 100 can be used.

[0047] The following takes a humidifier as an example to describe the technical solution of the present application in detail. This embodiment is only used as an example and does not limit the technical scope of the present application. Furthermore, the drawings in the embodiments also omit unnecessary components to clearly show the technical features of the present application.

[0048] See also Figure 2The humidifier includes a panel assembly structure 100, which includes a baffle 10 and a panel 20. The panel 20 is connected to the baffle 10, and the panel 20 has an operating part 21. The panel assembly structure 100 also includes a support member 31 and a circuit board 32 (PCB board). The circuit board 32 is connected to the support member 31 and receives a signal transmitted to it by the operating part 21 of the panel 20, that is, the operating part 21 of the operating panel 20 can trigger the PCB board. Specifically, the operating part 21 can be a key structure or a touchable display window structure.

[0049] The baffle 10 is provided with a first matching portion 11, the panel 20 is matched to the side of the baffle 10 where the first matching portion 11 is provided, the support member 31 is floatingly matched to the side of the panel 20 facing the baffle 10 in a direction approaching or away from the operating portion 21, and the circuit board 32 is matched to the support member 31 and is located on the operating path of the operating portion 21 moving toward the baffle 10 along the first direction.

[0050] The support member 31 is provided with a second matching portion 311, and the second matching portion 311 has deformation capability. The second matching portion 311 abuts against the first matching portion 11 and when the operating portion 21 moves along the first direction, the second matching portion 311 is elastically deformed under the squeezing action of the first matching portion 11, causing the support member 31 to float toward the direction close to the panel 20 and enabling the circuit board 32 to apply a reverse force to the operating portion 21, so as to achieve a close fit between the operating portion 21 of the panel 20 and the circuit board 32, that is, to achieve a close fit between the button structure or the touchable display window structure of the panel 20 and the circuit board 32.

[0051] The humidifier provided by the embodiment of the present invention, when operating the operating part 21 of the panel 20, that is, when a force is applied to the operating part 21 of the panel 20, the operating part 21 of the panel 20 applies a force to the circuit board 32 along a first direction, and the second matching part 311 is elastically deformed, causing the support member 31 to float toward the direction close to the panel 20 and causing the circuit board 32 to apply a reverse force to the operating part 21, thereby ensuring that the operating part 21 of the panel 20 is tightly fitted with the circuit board 32, that is, ensuring that the button structure or the touchable display window structure of the panel 20 is tightly fitted with the circuit board 32, thereby improving the operational sensitivity of the panel 20.

[0052] Continuing to refer to FIG. 2 , in one embodiment, the panel 20 and the baffle 10 define an assembly cavity 40, and the circuit board 32 and the support member 31 are located in the assembly cavity 40. During assembly, the support member 31 equipped with the circuit board 32 is first assembled on the baffle 10, and then the panel 20 is assembled outside the support member 31 equipped with the circuit board 32, so that the circuit board 32 and the support member 31 are surrounded in the assembly cavity 40. It should be understood that in other embodiments, the panel assembly structure 100 can also be arranged in other ways, which are not limited here.

[0053] The first matching portion 11 includes a plurality of first matching portions 11, and the second matching portion 311 includes a plurality of first matching portions 11, and each second matching portion 311 matches with each first matching portion 11. It should be understood that in some other embodiments, the first matching portion 11 and the second matching portion 311 may include only one, which is not limited here.

[0054] Furthermore, all the second matching parts 311 form an enclosed cavity, and all the first matching parts 11 are located in the enclosed cavity. That is, in this embodiment, each second matching part 311 is located outside each first matching part 11 matched therewith, so as to ensure the uniformity of deformation of each second matching part 311, so as to facilitate the close fit between each part of the PCB board and the operating part 21 of the panel 20.

[0055] See also Figure 3 The support member 31 includes a body 312, and the second matching portion 311 is fixedly connected to the body 312. Specifically, the body 312 has a first buckle 313 on the side facing the baffle 10, the PCB board is located between the side of the body 312 facing the baffle 10 and the baffle 10, and the PCB board is fixed to the body 312 through the first buckle 313, and the operating portion 21 of the panel 20 is arranged on the body 312 to contact the PCB board and apply a force to the PCB board.

[0056] See also Figure 3 and Figure 4 Each second matching portion 311 includes a cantilever 3111, which is connected to the body 312 and matches the first matching portion 11. When the operating portion 21 applies a force to the circuit board 32 along the first direction, the cantilever 3111 is elastically deformed and generates a component force that drives the support member 31 to float in a direction close to the panel 20, so that the circuit board 32 can apply a reverse force to the operating portion 21.

[0057] By setting the second matching portion 311 to include a cantilever 3111, the cantilever 3111 can be elastically deformed when subjected to a small external force, so that when the circuit board 32 is subjected to a small force, the cantilever 3111 can respond and elastically deform and generate a component force that drives the support member 31 to float in the direction close to the panel 20, so that a reverse force can be applied to the circuit board 32 toward the operating portion 21. It is conceivable that in other embodiments, the second matching portion 311 can also be set in other forms, which are not limited here.

[0058] Further, the extension direction of the cantilever 3111 is inclined relative to the first direction to generate the above-mentioned reverse force. Further, the cantilever 3111 is a curved structure. It should be understood that in other embodiments, the arrangement of the cantilever 3111 is not limited to the above-mentioned manner, and is not limited here.

[0059] Specifically, the cantilever 3111 of each second matching portion 311 is connected to the periphery of the body 312 and is inclined outward relative to the body 312 to form a flared support member 31 with an opening facing the baffle 10 .

[0060] Each first matching portion 11 has a first engaging portion 111, and each second matching portion 311 includes a second engaging portion 3112, and the second engaging portion 3112 is connected to an end of the cantilever 3111 away from the body 312. The panel assembly structure 100 has an intermediate state, in which the second engaging portion 3112 is engaged with the first engaging portion 111 (see Figure 5 and Figure 6 ) to limit the support member 31 from separating from the baffle 10 along the first direction.

[0061] When assembling the panel assembly structure 100, the support member 31 equipped with the circuit board 32 is first installed with the baffle 10, and then the panel 20 is assembled. Specifically, the panel 20 is engaged with the baffle 10. The intermediate state is a state where the support member 31 equipped with the circuit board 32 is assembled with the baffle 10, but the panel 20 has not yet been assembled. In the intermediate state, the second engaging portion 3112 is engaged with the first engaging portion 111, preventing the support member 31 from being separated from the baffle 10 along the first direction, so as to facilitate the assembly of the panel 20.

[0062] The panel assembly structure 100 also has an assembled state. In the assembled state, the second engaging portion 3112 is engaged with or separated from the first engaging portion 111 (see Figure 2 and Figure 7 The above-mentioned assembly state is the state after the panel 20 is assembled. Since the support member 31 is restricted by the panel 20 in the assembly state, the second engaging portion 3112 and the first engaging portion 111 can be engaged or separated. At this time, it is sufficient to ensure that the cantilever 3111 is elastically deformed when the PCB board is subjected to the force applied by the panel 20.

[0063] Specifically, the cantilever 3111 expands outwardly along the edge of the body 312 to form an arc shape, and the first engaging portion 111 abuts against the inner surface of the cantilever 3111 .

[0064] Furthermore, the baffle 10 is further provided with a first guide portion 12 (see Figure 8 ), the support member 31 is provided with a second guide portion 314 (continue to refer to Figure 3 and Figure 4 ), the second guide portion 314 cooperates with the first guide portion 12 to guide the assembly of the support member 31 and the baffle 10 in the first direction, thereby facilitating the assembly of the support member 31 and the baffle 10.

[0065] The first guide portion 12 cooperates with the second guide portion 314 to limit the position of the support member 31 relative to the baffle 10 in the second direction and the third direction, and the first direction, the second direction and the third direction intersect each other. Through the above arrangement, the first guide portion 12 cooperates with the second guide portion 314 to not only guide the assembly of the support member 31 and the baffle 10 in the first direction, but also limit the position of the support member 31 in the second direction and the third direction.

[0066] Specifically, one of the first guide portion 12 and the second guide portion 314 is a guide hole, and the other is a guide post that matches the guide hole. The guide post is inserted into the guide hole to guide the support member 31 and the baffle 10 to be assembled.

[0067] In a specific embodiment, the guide post is protruding from the side of the body 312 of the support member 31 facing the baffle 10, the guide hole is provided on the side of the baffle 10 facing the support member 31, and the guide post is penetrated in the PCB board and matched with the guide hole. Specifically, the guide hole can be a hole opened on a protruding post protruding on the baffle 10, or a hole directly opened on the baffle 10.

[0068] The guide post has a fixed end and a suspended end connected to each other, and the suspended end is cross-shaped. In this way, if the guide post interferes with the inner wall of the guide hole when inserted into the guide hole, the cross-shaped suspended end is easy to deform, which is convenient for the guide post to be inserted into the guide hole.

[0069] In another embodiment, the diameter of the suspended end may be smaller than the diameter of the fixed end, so that the guide post can be easily inserted into the guide hole.

[0070] See also Fig. 9 and Fig.10 In another embodiment, the assembly cavity 40 is omitted between the panel 20 and the baffle 10, and a through hole is provided at the position of the baffle 10 corresponding to the support member 31, and the first matching portion 11 is connected to the hole wall of the through hole. It can be understood that in other embodiments, the panel assembly structure 100 can also be arranged in other ways, which are not limited here.

[0071] The first matching parts 11 include a plurality of them, and the second matching parts 311 include a plurality of them equal to the number of the first matching parts 11, and each second matching part 311 matches with each first matching part 11. All the first matching parts 11 are surrounded to form an enclosure cavity, and all the second matching parts 311 are located in the enclosure cavity. That is, in this embodiment, each second matching part 311 is located in the first matching part 11 matched therewith, so as to ensure the uniformity of deformation of each second matching part 311, so as to facilitate the close fit between each part of the PCB board and the operating part 21 of the panel 20.

[0072] The support member 31 includes a body 312, and the second matching portion 311 is fixedly connected to the body 312. Specifically, the PCB board is arranged on the side of the support member 31 away from the baffle 10, so that the operating portion 21 of the panel 20 can contact the PCB board without passing through the support member 31 and apply force to the PCB board.

[0073] Each second mating portion 311 includes a cantilever 3111, which is connected to the body 312 and is mated with the first mating portion 11. When the operating portion 21 applies a force to the circuit board 32 along the first direction, the cantilever 3111 is elastically deformed and generates a component force driving the support member 31 to float in a direction close to the panel 20, so that the circuit board 32 can apply a reverse force to the operating portion 21.

[0074] By setting the second mating portion 311 to include a cantilever 3111, the cantilever 3111 can be elastically deformed when subjected to a small external force, so that when the circuit board 32 is subjected to a small force, the cantilever 3111 can respond by elastically deforming and generating a component force driving the support member 31 to float closer to the panel 20, so that a reverse force can be applied to the circuit board 32 toward the operating portion 21.

[0075] Further, the extension direction of the cantilever 3111 is inclined relative to the first direction to generate the above-mentioned reverse force. Further, the cantilever 3111 is a curved structure. It should be understood that in other embodiments, the arrangement of the cantilever 3111 is not limited to the above-mentioned manner, and is not limited here.

[0076] Specifically, the cantilever 3111 of each second matching portion 311 is connected to the periphery of the body 312 and tilted outward relative to the body 312 to form a flared support member 31 with an opening facing away from the baffle 10 .

[0077] Each first matching portion 11 has a first engaging portion 111, and each second matching portion 311 includes a second engaging portion 3112, and the second engaging portion 3112 is connected to an end of the cantilever 3111 away from the body 312. The panel assembly structure 100 has an intermediate state and an assembled state. In the intermediate state and the assembled state, the second engaging portion 3112 is engaged with the first engaging portion 111 (see Fig.11 ) to limit the support member 31 from separating from the baffle 10 along the first direction.

[0078] Specifically, in the assembled state, when the operating part 21 applies a force to the circuit board 32 along the first direction, the second locking part 3112 and the cantilever 3111 are elastically deformed together, causing the support member 31 to float toward the panel 20 and enabling the circuit board 32 to apply a reverse force to the operating part 21.

[0079] It is understandable that in other embodiments, when the operating portion 21 applies a force to the circuit board 32 along the first direction, the first mating portion 11 may elastically deform together with the second mating portion 311, or the first mating portion 11 may not deform, which is not limited here.

[0080] Continue reading Fig. 9 Further, the panel 20 includes a second buckle 22 , and the panel 20 is buckled with the baffle 10 via the second buckle 22 .

[0081] Another embodiment of the present invention further provides an electrical appliance including the panel assembly structure 100 . Specifically, the electrical appliance is a humidifier.

[0082] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
