The above schematic diagram is only to illustrate the structural relationships related to the utility model and is not intended as an actual scale of the product.

[0057] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides an electrical box for a range hood, including a main control board protective box 1 and a water pump protective box 2. The main control board protective box 1 has a mounting part 3 at its bottom and a water pump mounting position and a snap-fit ​​part 4 at its top. The water pump protective box 2 has a snap-fit ​​part 5 at its bottom. The snap-fit ​​part 4 and the snap-fit ​​part 5 are fitted together to connect the water pump protective box 2 to the top of the main control board protective box 1, so that the water pump protective box 2 covers the water pump mounting position.

[0058] Both the main control board protective box 1 and the water pump protective box 2 have openings at the bottom.

[0059] The main control board protective box 1 is a rectangular structure with an open bottom. It is typically made of high-temperature resistant, flame-retardant engineering plastics or metals, possessing good insulation and mechanical strength. Designed according to actual needs, it is generally capable of accommodating the main control board and its related components.

[0060] The bottom of the main control board protective box 1 is provided with a mounting part 3, which is usually a mounting hole, for fixing the main control board protective box 1 to the corresponding position of the range hood. The top of the main control board protective box 1 is provided with a snap-fit ​​part 4, which is used to fit and snap-fit ​​with the snap-fit ​​part 5 of the water pump protective box 2.

[0061] The main control board protection box 1 covers the main control board inside, effectively prevents external impurities such as dust and water vapor from entering, and improves the service life and reliability of the main control board.

[0062] The water pump protection box 2 is also a cuboid structure with an open bottom. It is usually made of corrosion-resistant and waterproof materials to ensure that it will not be damaged during long-term use in a humid environment. According to the actual size of the water pump, it is designed to ensure that the water pump can be installed smoothly and work normally.

[0063] The bottom of the water pump protection box 2 is provided with a clamping part 5 which is adapted to be clamped with the clamping part 4 on the top of the main control board protection box 1. The sidewall of the water pump protection box 2 is provided with a water pipe through hole 8 to facilitate the entry and exit of the water pipe and ensure the normal work of the water pump.

[0064] The water pump protection box 2 covers the water pump inside, effectively prevents water vapor and dust from entering, and improves the service life and reliability of the water pump.

[0065] By adapting the clamping part 5 at the bottom of the water pump protection box 2 to the clamping part 4 on the top of the main control board protection box 1, the water pump protection box 2 can be quickly and accurately installed on the main control board protection box 1, simplifying the installation process. When the water pump needs to be repaired, it can be easily disassembled by simply disengaging the clamping structure, which facilitates quick positioning and repair, improving maintenance efficiency.

[0066] In one embodiment, the clamping part 4 includes a rotating clamping part 41 and an elastic clamping part 42; the clamping part 5 includes a rotating clamping part 51 and an elastic clamping part 52; the rotating clamping part 41 is arranged on one side of the top of the main control board protection box 1, and the elastic clamping part 42 is arranged on the other side of the top of the main control board protection box 1; the rotating clamping part 51 is arranged on one side of the bottom of the water pump protection box 2, and the elastic clamping part 52 is arranged on the other side of the bottom of the water pump protection box 2; the rotating clamping part 41 is rotatably adapted to be clamped with the rotating clamping part 51; the elastic clamping part 42 is adapted to be clamped with the elastic clamping part 52 to limit the relative rotation of the rotating clamping part 41 and the rotating clamping part 51.

[0067] Align the rotating clamping part 51 at the bottom of the water pump protection box 2 with the rotating clamping part 41 on the top of the main control board protection box 1, and gently push and rotate the water pump protection box 2. The rotating clamping part 51 and the rotating clamping part 41 form a stable clamping state, ensuring that the water pump protection box 2 is connected stably on this side.

[0068] The water pump protection box 2 is rotated around the rotating clamping part 51 and the rotating clamping part 41, so that the elastic clamping part 52 at the bottom of the water pump protection box 2 is aligned with the elastic clamping part 42 at the top of the main control board protection box 1. The water pump protection box 2 is continuously rotated and gently pressed downward, so that the elastic clamping part 52 is adapted to be clamped with the elastic clamping part 42. Since the elastic clamping part 52 has a certain elasticity, it will be deformed during sliding in, and then return to its original state, clamped into the elastic clamping part 42, to form a stable clamping state.

[0069] In one embodiment, the rotating clamping part 41 includes a connecting plate 411 and an arc-shaped clamping plate 412; the connecting plate 411 is perpendicular to the top of the main control board protection box 1, one end of which is connected to the top of the main control board protection box 1, and the other end of which is connected to one end of the arc-shaped clamping plate 412; the other end of the arc-shaped clamping plate 412 and the top of the main control board protection box 1 form a clamping installation opening 414, and the rotating clamping part 51 is embedded in the concave arc surface of the arc-shaped clamping plate 412 through the clamping installation opening 414 and can rotate relative to the arc-shaped clamping plate 412.

[0070] The connecting plate 411 plays a role in supporting and fixing the arc-shaped clamping plate 412, ensuring the stability of the arc-shaped clamping plate 412. The design of the arc-shaped clamping plate 412 allows the rotating clamping part 51 of the water pump protection box 2 to enter the rotating clamping part 41 through the clamping installation opening 414 and rotate and clamp with the arc-shaped clamping plate 412, achieving stable connection.

[0071] In another embodiment, the rotating clamping part 41 further includes a guide plate 413; the guide plate 413 is parallel to the top of the main control board protection box 1; one end of the guide plate 413 is connected to the end of the arc-shaped clamping plate 412 away from the connecting plate 411; and the end of the arc-shaped clamping plate 412 away from the connecting plate 411 and the guide plate 413 and the top of the main control board protection box 1 form the clamping installation opening 414. The design of the guide plate 413 increases the length of the clamping installation opening 414, helps guide the rotating clamping part 51 of the water pump protection box 2 to smoothly enter the clamping installation opening 414, reduces the installation difficulty, and improves the installation precision.

[0072] The rotating clamping part 41 is of an integrated structure. The rotating clamping part 41 and the main control board protection box 1 can also be of an integrated structure. The integrated design reduces the number of connection points, thereby reducing potential failure points and improving the overall structural firmness and reliability.

[0073] In one embodiment, the rotating clamping part 51 is a clamping column; the side of the water pump protection box 2 corresponding to the rotating clamping part 41 is provided with a notch 10, and the clamping column is arranged in the notch 10. Specifically, the clamping column is of a cylindrical structure, and a gap is left between the side surface of the clamping column and the water pump protection box 2, and the thickness of the gap is basically the same as the thickness of the guide plate 413 and the thickness of the arc-shaped clamping plate 412.

[0074] The notch 10 is arranged at one side of the bottom of the water pump protection box 2. The notch 10 provides installation space for the clamping column, ensuring that the clamping column can be smoothly clamped into the rotating clamping portion 41 of the main control board protection box 1.

[0075] The clamping column at the bottom of the water pump protection box 2 is aligned with the clamping installation port 414 at the top of the main control board protection box 1. The water pump protection box 2 is gently pushed, and the clamping column slides along the guide plate 413 at the top of the main control board protection box 1 (at this time, the guide plate 413 is inserted into the gap between the clamping column and the water pump protection box 2), and enters the arc-shaped clamping plate 412, so that the clamping column is completely clamped into the arc-shaped clamping plate 412. It is confirmed that the clamping column has been completely clamped into the arc-shaped clamping plate 412. Ensure that the connection between the rotating clamping portion 41 and the rotating clamping portion 51 is stable and reliable.

[0076] Here, the arc-shaped clamping plate 412 is a semi-cylindrical structure, and the inner diameter of the circle is matched with the outer diameter of the clamping column.

[0077] In order to ensure the stability of the connecting mechanism, the rotating clamping portion 41 is two and arranged at intervals. Similarly, the rotating clamping portion 51 is also two and arranged at intervals. The two rotating clamping portions 41 and the two rotating clamping portions 51 are arranged one by one.

[0078] In one embodiment, the elastic clamping portion 42 is an elastic clamping protrusion. Specifically, each elastic clamping portion 42 includes two elastic clamping protrusions arranged at intervals, and a pair of elastic clamping protrusions constitutes an elastic clamping portion 42. The elastic clamping protrusion is usually made of elastic material such as plastic, which can deform and restore during installation.

[0079] The elastic clamping protrusion includes a connecting protrusion 421 and a clamping protrusion 422; one end of the connecting protrusion 421 is connected with the side of the top of the main control board protection box 1, and the other end is connected with the clamping protrusion 422. The outer side of the top of the clamping protrusion 422 is provided with a guide inclined surface 423.

[0080] The connecting protrusion 421 plays a role in fixing and supporting the clamping protrusion 422, ensuring that the elastic clamping protrusion can remain stable under stress. The clamping protrusion 422 is columnar or semispherical, with a slightly inclined top forming a guide inclined surface 423. The outer side of the top of the clamping protrusion 422 is provided with a guide inclined surface 423, which facilitates the sliding of the elastic clamping portion 52 of the water pump protection box 2 into the guide inclined surface 423.

[0081] The elastic clamping part 52 at the bottom of the water pump protection box 2 is aligned with the elastic clamping part 42 (i.e. the elastic clamping protrusion) at the top of the main control board protection box 1. The water pump protection box 2 is gently pressed downward, and the elastic clamping protrusion slides into the elastic clamping part 52 through the guide of the guide slope 423. During the pressing process, the guide slope 423 of the two elastic clamping protrusions is in contact with the elastic clamping part 52, and the two elastic clamping protrusions are close to each other. Because the elastic clamping protrusion has a certain elasticity, it will deform during the sliding process, gradually compressing and approaching. When the elastic clamping protrusion completely slides into the elastic clamping part 52, the two elastic clamping protrusions will return to their original state due to the elasticity of the elastic material. The elastic clamping protrusion that returns to its original state will be clamped in the elastic clamping part 52, forming a stable clamping state.

[0082] Here, the elastic clamping part 42 is of an integrated structure, and the elastic clamping part 42 and the main control board protection box 1 can also be of an integrated structure.

[0083] In an embodiment, the elastic clamping part 52 is a clamping hole; the bottom of the water pump protection box 2 is provided with a mounting plate 6 corresponding to one side of the elastic clamping part 42, and the mounting plate 6 is provided with a clamping hole. The mounting plate 6 is arranged on the outside of the bottom of the water pump protection box 2 and protrudes from the water pump protection box 2. The clamping hole is a through hole penetrating the mounting plate 6. The clamping hole is a rectangular through hole, and the width of each clamping hole is adapted to the distance between the outer side walls of the two connecting protrusions 421 included in one elastic clamping protrusion.

[0084] The mounting plate 6 and the water pump protection box 2 can be of an integrated structure.

[0085] In order to ensure the stability of the connecting mechanism, the elastic clamping part 42 is two and is arranged in a spaced manner. Similarly, the elastic clamping part 52 is also two and is arranged in a spaced manner. The two elastic clamping parts 42 and the two elastic clamping parts 52 are arranged one by one.

[0086] As shown in the figure, one side of the top of the main control board protection box 1 is sunken downward to form a box body mounting position 7 of the water pump protection box 2; the box body mounting position 7 is provided with a clamping part 4. The rotating clamping part 41 is arranged close to the inner side of the box body mounting position 7, and the elastic clamping part 42 is arranged close to the outer side of the box body mounting position 7.

[0087] The rotating clamping part 51 at the bottom of the water pump protection box 2 is aligned with the rotating clamping part 41 at the top of the main control board protection box 1. The water pump protection box 2 is gently pushed to make the rotating clamping part 51 slide along the guide plate 413 into the arc-shaped clamping plate 412 until the rotating clamping part 51 is completely clamped into the rotating clamping part 41.

[0088] After ensuring that the rotating engaging portion 51 has been properly engaged with the rotating engaging portion 41, continue to rotate and gently press downward the water pump protection box 2. At this time, the elastic engaging portion 52 (i.e. the engaging hole) at the bottom of the water pump protection box 2 should be aligned with the elastic engaging portion 42 (i.e. the elastic engaging protrusion) at the top of the main control board protection box 1.

[0089] Continue to apply slight pressure to allow the elastic engaging protrusion to slide into the elastic engaging portion 52 through the guidance of the lead-in slope 423. During this process, the elastic engaging protrusion will be deformed to adapt to the shape of the engaging hole, and then return to its original shape after the pressure is released, thereby forming a firm engagement.
