[0037] This utility model proposes an electrical device 100.

[0038] Please see Figures 1 to 4In one embodiment of this utility model, the electrical device 100 includes a housing 1, a handle 2, an elastic element 31, and a connecting seat 32. The housing 1 is the outer shell or at least part of the outer shell of the electrical device 100. The handle 2 is disposed on the outer side wall of the housing 1 through the elastic element 31 and the connecting seat 32. Specifically, the housing 1 is provided with an assembly hole 1a, and the handle 2 is formed with an installation cavity 21a and a through hole 21b communicating with the installation cavity 21a. The elastic element 31 is disposed in the installation cavity 21a and one end is connected to the inner wall of the installation cavity 21a, and the other end is disposed toward the through hole 21b. The connecting seat 32 is movably disposed in the installation cavity 21a and connected to the end of the elastic element 31 facing the through hole 21b. The elastic element 31 can generate elastic deformation under the action of external force so that the connecting seat 32 can be movably inserted through the through hole 21b. At least part of the connecting seat 32 is driven by the elastic member 31 and is engaged in the assembly hole 1a through the through hole 21b. The connecting seat 32 is rotatably engaged with the through hole 21b and / or the assembly hole 1a, so that the handle 2 is rotatably connected to the housing 1.

[0039] Furthermore, the handle 2 has an opening on its side wall that communicates with the mounting cavity 21a and is spaced apart from the through hole 21b. During assembly, the connecting seat 32 and the elastic element 31 can be installed into the mounting cavity 21a of the handle 2 from the opening. The connecting seat 32 passes through the through hole 21b and is connected to the elastic element 31. At this time, the elastic element 31 applies an elastic force to the connecting seat 32 so that at least part of the connecting seat 32 extends out of the through hole 21b. The mounting cavity 21a has clearance space for the connecting seat 32 to move. When the handle 2 is installed into the housing 1, the connecting seat 32 is pressed first so that it moves into the mounting cavity 21a along the axial direction of the through hole 21b. The elastic element 31 undergoes elastic deformation after being squeezed. When the through hole 21b and the assembly hole 1a are aligned, the elastic element 31 rebounds and drives at least part of the connecting seat 32 to extend out of the through hole 21b and be locked in the assembly hole 1a.

[0040] After prolonged use, the handle 2 or the connecting seat 32 may deform or shift. The elastic force continuously applied by the elastic element 31 can compensate for the displacement of the connecting seat 32, thus maintaining the stability of the connection structure. As can be seen, the elastic element 31 and connecting seat 32 proposed in this invention facilitate the quick installation of the handle 2. By setting the elastic element 31 to limit the connection seat 32 and prevent displacement, the problem of unstable connection between the handle 2 and the outer casing in existing electrical equipment 100 can be solved.

[0041] Furthermore, the connecting seat 32 can be configured to rotate with the through hole 21b, that is, when the handle 2 rotates, the connecting seat 32 rotates relative to the handle 2 and is fixed relative to the housing 1; or, the connecting seat 32 can be configured to rotate with the assembly hole 1a, that is, when the handle 2 rotates, the connecting seat 32 is fixed relative to the handle 2 and rotates relative to the housing 1; or, the connecting seat 32 can also be configured to rotate with both the through hole 21b and the assembly hole 1a, so as to achieve a rotatable connection between the handle 2 and the housing 1. The specific structure can be designed according to the requirements.

[0042] It should be noted that the mounting hole 1a on the housing 1 can be a round hole, a square hole, a polygonal hole, or an irregularly shaped hole. The shape of the connecting seat 32 can be set to match the shape of the mounting hole 1a, so that the connecting seat 32 can be stably locked in the mounting hole 1a and the handle 2 can be rotatably connected to the housing 1. The elastic element 31 can be set as a spring, a sheet, or other components. The elastic element 31 can generate elastic deformation or displacement to avoid or limit the connecting seat 32. As for which structure to choose, it can be designed and selected according to actual needs, and no specific limitation is made here.

[0043] like Figures 2 to 5 As shown, in one embodiment of this utility model, the end of the handle 2 is bent to form a connecting arm 21. One side of the end of the connecting arm 21 is provided with a mounting cavity 21a and a through hole 21b communicating with the mounting cavity. The outer wall of the housing 1 is provided with a receiving groove 1b whose shape matches the handle 2. An assembly hole 1a is formed on the groove wall of the receiving groove 1b. The connecting seat 32 is rotatably engaged in the assembly hole 1a, so that the handle 2 is rotatably housed within the receiving groove 1b. The assembly hole 1a can be formed on the side wall or bottom wall of the receiving groove 1b, and can be adapted according to the installation position of the handle 2 (such as the upper surface or side of the housing 1) and the installation orientation (horizontal installation, vertical installation), without any specific limitations. It is understood that providing a receiving groove 1b to accommodate the handle 2 saves space, and the handle 2 not protruding makes the overall appearance of the electrical equipment 100 simple and beautiful. Furthermore, the handle 2 stored in the receiving groove 1b avoids accidental contact or pulling, which helps reduce the risk of accidental injury.

[0044] like Figure 5 As shown, in one embodiment of this utility model, the axial direction of the connecting seat 32 and the mounting hole 1a is arranged in the horizontal direction. The connecting seat 32 is movable along the axial direction of the mounting hole 1a, so that the connecting seat 32 has a first position and a second position in the horizontal direction. When the connecting seat 32 is in the first position, the portion of the connecting seat 32 extending out of the through hole 21b retracts into the through hole 21b. The total width of the connecting seat 32 and the connecting arm 21 in the axial direction of the mounting hole 1a is less than or equal to the width of the groove opening of the receiving groove 1b, so that the connecting arm 21 of the handle 2 can be embedded into the receiving groove 1b.

[0045] When the connecting seat 32 is in the second position, the connecting seat 32 extends at least partially out of the through hole 21b and is engaged in the assembly hole 1a. The total width of the connecting seat 32 and the connecting arm 21 in the axial direction of the assembly hole 1a is greater than the width of the groove opening of the receiving groove 1b. At this time, the connecting seat 32 limits the connection of the handle 2 to the housing 1. It can be understood that the width of the receiving groove 1b is exactly matched with the width of the connecting arm 21 of the handle 2, ensuring that the connecting arm 21 of the handle 2 is stably stored in the receiving groove 1b, avoiding the handle 2 from shaking or shifting, and maximizing space saving. The receiving groove 1b completely hides or stores the handle 2, making the appearance of the equipment look more concise and neat, which helps to improve the aesthetics of the product.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the two ends of the handle 2 are bent in the same direction to form two connecting arms 21. Each connecting arm 21 has a connecting seat 32 on its inner side. The two connecting seats 32 are arranged opposite to each other on the handle 2, and their rotation axes coincide. The shape of the receiving groove 1b matches the shape of the handle 2, and an assembly hole 1a is provided on the groove wall of the receiving groove 1b corresponding to each of the two connecting seats 32. The handle 2 is connected to the housing 1 through the connecting parts on the two connecting arms 21, which can improve the structural strength and connection stability. In some other embodiments of this utility model, the handle 2 can be provided with one connecting arm 21 and one connecting seat 32 to connect to the housing 1, or the handle 2 can also be provided with multiple (more than two) connecting arms 21 and connecting seats 32 to connect to the housing 1, which can be designed according to actual needs.

[0047] like Figure 6 and Figure 7 As shown, in one embodiment of this utility model, the electrical device 100 further includes a press-and-rebound mechanism 4. Specifically, the press-and-rebound mechanism 4 is disposed in the receiving groove 1b and abuts against the surface of the handle 2. The user can trigger the press-and-rebound mechanism 4 by pressing the handle 2. After the press-and-rebound mechanism 4 is triggered, the handle 2 can be pushed out of the receiving groove 1b, making it convenient for the user to grip and rotate the handle 2. After use, the handle 2 is put back into the receiving groove 1b and the press-and-rebound mechanism 4 is triggered again, so that the handle 2 is received in the receiving groove 1b. It should be noted that the press-and-rebound mechanism 4 can adopt a rotating ratchet structure, a telescopic buckle structure, a torsion spring and a cam structure, etc. The above structures are similar in principle to the press-and-rebound mechanism 4 of a ballpoint pen. By repeatedly pressing the handle 2 to trigger the mechanism, the handle 2 can be quickly disengaged from the receiving groove 1b, making it convenient for the user to operate.

[0048] like Figure 6 and Figure 7As shown, in one embodiment of this utility model, the press-and-rebound mechanism 4 includes a rebound body 41 and a telescopic column 42 disposed on the rebound body 41. The housing 1 has a receiving cavity, and the bottom wall of the receiving groove 1b is provided with a mounting hole communicating with the receiving cavity. The rebound body 41 is disposed in the receiving cavity of the housing 1, and the telescopic column 42 is movably inserted through the mounting hole. Please refer to [reference needed]. Figure 6 The telescopic column 42 is in a retracted state on the rebound body 41, and the handle 2 can be stored in the receiving slot 1b. Please refer to [reference needed]. Figure 7 The telescopic column 42 is in an extended state on the rebound body 41, and the telescopic column 42 pushes the handle 2 out of the receiving groove 1b. By pressing the telescopic column 42 with the handle 2, the telescopic column 42 can switch between the retracted state and the extended state, realizing the quick storage and ejection of the handle 2.

[0049] like Figure 5 As shown, in one embodiment of this utility model, the assembly hole 1a is a circular hole, and the end of the connecting seat 32 away from the handle 2 is provided with a cylindrical rotating shaft portion 321. This rotating shaft portion 321 is rotatably disposed in the assembly hole 1a, so that the handle 2 is rotatably connected to the housing 1. Furthermore, the receiving groove 1b is opened on the upper surface of the housing 1 with the groove opening facing upwards. The assembly hole 1a is disposed on the side wall of the receiving groove 1b and its axis is arranged horizontally. The receiving groove 1b being located on the upper surface of the housing 1 facilitates the placement and removal of the handle 2 and improves the overall aesthetics of the electrical equipment 100. Furthermore, in one embodiment of this utility model, as... Figure 1 and Figure 2 As shown, a clearance groove 1c is also provided on the upper surface of the housing 1. The clearance groove 1c is located at the opening of the receiving groove 1b to allow the handle 2 to be taken out by hand, thereby improving the ease of use.

[0050] like Figure 5 As shown, in one embodiment of this utility model, the elastic element 31 includes a columnar spring 311 disposed on the handle 2. Specifically, one end of the spring 311 is connected to the connecting seat 32, and the other end of the spring 311 is connected to the inner wall of the mounting cavity 21a. The spring 311 has the characteristic of elastic deformation under external force. The connecting seat 32 compresses the spring 311 under external force and moves back and forth between the first position and the second position. Further, in one embodiment of this utility model, the elastic element 31 can also be configured as a spring sheet structure, and one end of the elastic element 31 is connected to the handle 2 and configured as an integral structure. The connecting seat 32 is disposed at the other end of the elastic element 31. By pressing the connecting seat 32, the elastic element 31 is bent, so that the connecting seat 32 can move between the first position and the second position. Therefore, the specific structure of the elastic element 31 cooperating with the connecting seat is not limited.

[0051] like Figure 5As shown, in one embodiment of this utility model, a limiting part 322 is provided at the end of the connecting seat 32 away from the mounting hole 1a. The width of the limiting part 322 is greater than the diameter of the through hole 21b. The spring 311 applies a force to the connecting seat 32 so that the side wall of the limiting part 322 abuts against the inner wall of the mounting cavity 21a. The limiting part 322 is used to limit the length of the rotating shaft part 321 of the connecting seat 32 extending out of the through hole 21b and to prevent the connecting seat 32 from disengaging from the connecting arm 21. It can be understood that by setting the limiting part 322 to limit the connecting seat 32, the elastic member 31 is still in a compressed state when the connecting seat 32 is in the second position. The continuous application of force by the elastic member 31 to the connecting seat 32 is beneficial to the structural stability.

[0052] like Figure 5 As shown, in one embodiment of this utility model, a first limiting groove 322a is recessed on the limiting portion 322 of the connecting seat 32 facing the spring 311, and a second limiting groove 21c is provided on the side wall of the mounting cavity 21a opposite to the through hole 21b. One end of the elastic member 31 is limited and abuts against the first limiting groove 322a, and the other end is limited and abuts against the second limiting groove 21c. It can be understood that the first limiting groove 322a and the second limiting groove 21c facilitate the positioning and installation of the spring 311, effectively fix the two ends of the spring 311, prevent it from falling off the installation position due to vibration, impact, deformation, etc. during use, and ensure its stable operation.

[0053] In one embodiment of the present invention, the electrical device 100 includes a dehumidifier, which has a housing 1, a handle 2, an elastic element 31, and a connecting seat 32 and their cooperating structure as described in any of the foregoing embodiments.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
