[0038] See Figure 1 An embodiment of this application provides an electrical device (not shown) including a housing assembly that serves to accommodate, protect, and fix the device.

[0039] The following description uses a water purifier (specifically an under-sink water purifier) ​​as an example to illustrate the structure of the outer casing assembly in this application. The following embodiments are merely illustrative and do not limit the technical scope of this application. It is understood that in other embodiments, the electrical appliance may also be other devices with an outer casing assembly, such as countertop water purifiers, water dispensers, etc., and this is not limited thereto.

[0040] Please see Figures 1 to 4 The housing assembly 100 includes a main housing 20 and at least one panel 40. The main housing 20 is configured to form a receiving cavity 20a and at least one mounting port 20b communicating with the receiving cavity 20a. The main housing 20 has a housing mounting edge 25 circumferentially surrounding the mounting port 20b, and a stop 252 is protruding from the inner surface of the housing mounting edge 25. The panel 40 includes a panel body 41 and a panel mounting edge 43 circumferentially surrounding the panel body 41, and the panel mounting edge 43 is correspondingly inserted into one of the mounting ports 20b.

[0041] The panel mounting edge 43 is located between the housing mounting edge 25 and the stop 252. At least a portion of the outer surface of the panel mounting edge 43 is engaged with at least a portion of the inner surface of the housing mounting edge 25. The side surface of the stop 252 facing the housing mounting edge 25 abuts against a portion of the inner surface of the panel mounting edge 43.

[0042] The inner surface of the panel mounting edge 43 is the side surface of the panel mounting edge 43 that is close to the center point of the panel body 41, and the outer surface of the panel mounting edge 43 is the side surface of the panel mounting edge 43 that is away from the center point of the panel body 41. The inner surface and the outer surface of the panel mounting edge 43 are arranged opposite to each other in the thickness direction of the panel mounting edge 43.

[0043] The inner surface of the aforementioned housing assembly edge 25 is the side surface of the housing assembly edge 25 that is close to the mounting port 20b, and the outer surface of the housing assembly edge 25 is the side surface of the housing assembly edge 25 that is away from the mounting port 20b. The inner and outer surfaces of the housing assembly edge 25 are arranged opposite to each other in the thickness direction of the housing assembly edge 25.

[0044] In the aforementioned housing assembly 100, the beveled fit between the panel mounting edge 43 and the housing mounting edge 25 not only enables self-positioning compensation during assembly but also improves the uniformity of stress distribution, significantly enhancing appearance flatness and sealing performance. Furthermore, the guiding effect of the beveled surface effectively reduces assembly difficulty and increases production efficiency.

[0045] On the other hand, the stop 252 provided on the main housing 20 can play the role of positioning, limiting and enhancing structural stability. It can not only make the main housing 20 and the panel 40 accurately aligned, but also improve the overall structural strength of the housing assembly 100, effectively prevent the main housing 20 and the panel 40 from loosening due to external force or vibration. In addition, it can effectively control the assembly gap and further improve the appearance flatness.

[0046] Please continue reading. Figures 1 to 4 In some embodiments, the housing assembly 100 has a hollow cuboid structure. In the following embodiments, the length direction of the housing assembly 100 is defined as the first direction (i.e., Figure 1 The X direction is the first direction, and the width direction is the second direction (i.e., the second direction). Figure 1 The Y-direction is the middle direction, and the height direction is the third direction (i.e., Figure 1 In the Z direction, the first direction, the second direction, and the third direction intersect each other. In a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0047] Furthermore, the main housing 20 includes an integrally formed bottom wall 21, top wall 22, first side wall 23, and second side wall 24. The bottom wall 21 and top wall 22 are spaced apart and parallel in a third direction, while the first side wall 23 and second side wall 24 are spaced apart and parallel in a second direction. The first side wall 23 connects to one side edge of the bottom wall 21 and top wall 22 at opposite ends in the third direction, and the second side wall 24 connects to the other side edge of the bottom wall 21 and top wall 22 at opposite ends in the third direction.

[0048] Thus, the main housing 20 is constructed to form a receiving cavity 20a and two mounting ports 20b. The two mounting ports 20b are located at opposite ends of the main housing 20 in the first direction. The two side edges of the bottom wall 21, top wall 22, first side wall 23 and second side wall 24 respectively form two housing assembly edges 25 that surround the two mounting ports 20b in the circumferential direction.

[0049] It is understood that in some other embodiments, the shape of the main housing 20 is not limited to this, and the number and position of the mounting ports 20b can also be set as needed to meet different requirements.

[0050] Corresponding to the number of mounting ports 20b, there are two panels 40. It is understood that in some other embodiments, the number of panels 40 may not be two but may correspond to the number of mounting ports 20b. The shapes of different panels 40 may be the same or different, and the installation methods of different panels 40 may be the same or different.

[0051] In some embodiments, the panel 40 includes a panel body 41 and a panel mounting edge 43. The panel body 41 has a rectangular plate-like structure, the length direction of the panel 40 is parallel to a third direction, the width direction of the panel 40 is parallel to a second direction, and the thickness direction of the panel 40 is parallel to a first direction. The panel mounting edge 43 extends from the edge of the panel body 41 along the first direction toward the same side of the panel body 41, and forms a rectangular frame structure around the panel body 41 in the circumferential direction.

[0052] like Figure 4 As shown, in order to achieve a beveled fit, in some embodiments, the outer surface of the panel mounting edge 43 has a panel mounting surface 43a and a panel limiting surface 43b. The panel mounting surface 43a is located on the side of the panel mounting edge 43 away from the panel body 41. From the side closer to the panel body 41 to the side away from the panel body 41, the panel limiting surface 43b extends outward at an angle, and the panel mounting surface 43a extends inward at an angle. Therefore, the outer diameter of the panel 40 first gradually increases and then gradually decreases. The side of the panel 40 with the panel mounting surface 43a mates with the main housing 20, while the side of the panel 40 with the panel limiting surface 43b is located outside the main housing 20.

[0053] Matching the panel mounting edge 43, from the side near the receiving cavity 20a to the side away from the receiving cavity 20a, the inner surface of the housing mounting edge 25 extends outward at an angle to form a housing mounting surface that mates with the panel mounting surface 43a. The inner diameter of the mounting opening 20b gradually increases, and the tilt angle of the panel mounting surface 43a matches the tilt angle of the housing mounting surface.

[0054] Thus, during the process of inserting the panel assembly edge 43 into the mounting port 20b, the beveled surfaces of the two can achieve a self-positioning compensation function during the assembly process, enabling the panel 40 and the main housing 20 to automatically align within a certain axial offset range, effectively absorbing gap fluctuations caused by manufacturing tolerances. Furthermore, by increasing the contact area between the two, the uniformity of stress distribution can be improved, reducing the risk of local stress concentration and significantly improving the appearance flatness and sealing performance. In addition, the guiding effect of the beveled surfaces can effectively reduce assembly difficulty and improve production efficiency.

[0055] like Figure 5As shown, in some other embodiments, the outer surface of the panel mounting edge 43 extends inward from the side near the panel body 41 to the side away from the panel body 41 to form a panel mounting surface 43a, and the outer diameter of the panel 40 gradually decreases, so that the panel mounting edge 43 can be completely inserted into the main housing 20.

[0056] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the housing assembly edge 25 is provided with a plurality of stops 252, all of which are spaced apart circumferentially along the mounting opening 20b. Specifically, in one embodiment, the housing assembly edge 25 is provided with a plurality of stops 252, all of which are spaced apart circumferentially along the mounting opening 20b.

[0057] In one specific embodiment, the housing assembly edge 25 is provided with nine sets of stops 252. Each set of stops 252 includes two stops 252 spaced apart. One set of stops 252 is located on the top wall 22, three sets of stops 252 are located on the first side wall 23, three sets of stops 252 are located on the second side wall 24, and two sets of stops 252 are located on the bottom wall 21. It is understood that the number and location of the stops 252 are not limited to this and can be set as needed to meet different limiting requirements.

[0058] Furthermore, each stop 252 has an "L"-shaped structure, including a first stop 2521 and a second stop 2523. The first stop 2521 is connected to the housing mounting edge 25, one end of the second stop 2523 is connected to the first stop 2521, and the other end of the second stop 2523 extends away from the receiving cavity 20a. The panel mounting edge 43 is located between the housing mounting edge 25 and the second stop 2523, and abuts against the first stop 2521 in a first direction.

[0059] Thus, the cooperation between the stop 252 and the panel mounting edge 43 not only ensures precise alignment between the main housing 20 and the panel 40, preventing uneven gaps or functional failures due to misalignment during assembly, but also enhances the overall structural strength of the housing assembly 100 through the constraint effect of the surface contact between the stop 252 and the panel mounting edge 43. This effectively prevents the main housing 20 and the panel 40 from loosening due to external forces or vibrations. Furthermore, it effectively controls the assembly gap and further improves the smoothness of the appearance.

[0060] Please see Figures 6 to 8 In some embodiments, the housing mounting edge 25 is further provided with at least one main housing buckle 254, and the panel mounting edge 43 is further provided with at least one panel buckle 432. Each main housing buckle 254 and a panel buckle 432 are mated to each other in the mounting direction (i.e., the first direction) of the panel 40.

[0061] In some embodiments, each main housing snap-fit ​​254 is arranged adjacent to at least one stop 252. Therefore, the main housing snap-fit ​​254 and the at least one stop 252 are subjected to opposite forces, thus achieving a balancing effect and effectively preventing the housing assembly edge 25 from collapsing. Specifically, in one embodiment, the housing assembly edge 25 is provided with a plurality of main housing snap-fits 254. All main housing snap-fits 254 are arranged at intervals along the circumference of the mounting opening 20b, and each main housing snap-fit ​​254 is located between two adjacent stops 252 in the same group to form a whole. This simplifies the structure of the main housing 20 and improves the structural strength of the main housing snap-fits 254 and the stops 252.

[0062] In some embodiments, the housing assembly edge 25 is provided with at least one main housing fixing part 256, and the panel assembly edge 43 is provided with at least one panel fixing part 434. One end of the main housing fixing part 256 can be inserted into the panel fixing part 434. The housing assembly 100 also includes fasteners such as screws, which pass through the panel fixing part 434 and are inserted into the main housing fixing part 256 in a first direction.

[0063] In one specific embodiment, the housing assembly edge 25 is provided with two main housing fixing parts 256, which are located on the bottom wall 21 and the top wall 22, respectively. The panel assembly edge 43 is provided with two panel fixing parts 434, which are located on opposite sides of the panel assembly edge 43 in the first direction.

[0064] The panel fixing part 434 includes a columnar panel fixing part body 4341 and limiting ribs 4343. The central axis of the panel fixing part body 4341 is parallel to the first direction, and a plurality of limiting ribs 4343 are circumferentially spaced on the end face of the panel fixing part body 4341 away from the panel body 41. The main housing fixing part 256 has a columnar structure, and the central axis of the main housing fixing part 256 extends along the first direction. One end of the main housing fixing part 256 can be inserted into the limiting ribs 4343 to abut against one end face of the panel fixing part body 4341. Fasteners can pass through the main housing fixing part 256 along the first direction and be inserted into the panel fixing part body 4341, thereby fixing the two together.

[0065] In this way, the housing assembly edge 25 and the panel assembly edge 43 are quickly positioned and initially fixed through the main housing buckle 254 and the panel buckle 432. Elastic deformation can be used to absorb assembly errors and provide initial locking force. At the same time, the rigid connection of the fasteners further enhances the structural strength and stability, effectively preventing loosening caused by vibration, impact or long-term use. The synergistic effect of the two can not only improve assembly efficiency and reliability, but also achieve a tight fit between the main housing 20 and the panel 40, effectively control the gap and enhance the overall structure's resistance to deformation.

[0066] The aforementioned housing assembly 100 and the electrical equipment equipped with the housing assembly 100 are assembled in a manner where the panel 40 is not only installed in the mounting opening 20b by means of bevel fitting and tensioning of the stop 252, but the stop 252 of the panel 40 can also be fixed in the mounting opening 20b by means of snap-fit ​​and / or fastener fixing. This composite assembly scheme achieves a systematic improvement in assembly accuracy through multi-dimensional structural optimization, effectively controls assembly gaps, significantly improves the appearance flatness of the housing assembly 100, and improves production efficiency.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
