Technical Field

[0001] The utility model relates to the technical field of range hoods, and more specifically to a connecting wire structure of a range hood switch box. Background Art

[0002] Range hoods are usually equipped with a range hood switch box for displaying and controlling the operating status. Traditional range hood switch boxes usually use sealants to seal the outlet of the connecting wires. However, during use, the swing of the connecting wires may cause the sealants to loosen, thus affecting the fixing and sealing effect of the connecting wires. In addition, the use of sealants also increases the production process and reduces production efficiency.

[0003] In addition, since a large amount of water vapor and oil smoke will be generated during the use of the range hood, the traditional connecting wire structure may not be able to effectively prevent these harmful substances from entering the switch box, thereby causing corrosion to the internal circuit board and affecting the reliability and life of the equipment.

[0004] Therefore, it is necessary to provide a connecting wire structure that can achieve stable fixation of the connecting wire through the cooperation of a new type of wire card and card slot, avoid the use of sealant, improve the sealing of the connecting wire, and prevent water vapor and oil smoke from entering the switch box to enhance the overall performance of the switch box.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0025] A connection line structure of a range hood switch box includes a switch box 100 and a line card connection line 200 connected to the switch box 100. The switch box 100 is arranged on the range hood as a display or operating component of the range hood. The switch box 100 is installed on and connected to the range hood. The switch box 100 can display the working status of the range hood and is provided with buttons for controlling the working status of the range hood. The switch box 100 is usually arranged on the front surface of the range hood. The switch box 100 is provided with a cover 110 and a rear cover 120, which are combined to form the overall housing of the switch box 100. The line card connecting wire 200 is provided with a connecting wire 210 and a line card 220. The rear cover 120 is provided with a card slot 130 matching the line card 220 at the connection with the cover 110. In other embodiments, the card slot 130 can be provided on the cover 110, and the line card 220 can be sealed and embedded in the card slot 130, so that the line card connecting wire 200 is fixed to the switch box 100 through the card slot 130 and the card slot 130. The connecting wire 210 is assembled on the switch box 100 through the card slot 220, so that the opening of the switch box 100 for leading out the connecting wire 210 can be sealed, and it is ensured that the connecting wire 210 is fixed reliably. Since the range hood will be exposed to a large amount of water vapor and oil smoke during use, the card slot 130 can be sealed by the card card 220 to prevent water vapor or oil smoke from entering the switch. The inside of the switch box 100 is closed to prevent the internal circuit board 140 from being corroded, which plays a good protective role for the circuit board 140; the traditional range hood switch box will apply sealant at the wire outlet to achieve sealing, but after the range hood switch box is assembled and glued, during the packaging, transportation, and assembly to the range hood, the sealant may loosen as the connecting wire swings, which in turn causes the connecting wire to loosen or fall off, resulting in poor sealing or fixing effects. The utility model cooperates with the structure of the wire clip 220 and the card slot 130 to ensure that the connecting wire 210 is stable and prevented from loosening, thereby ensuring the sealing effect after the switch box 100 is assembled with the wire clip connecting wire 200. In addition, sealant is no longer used to fix the connecting wire 210, which reduces the process and saves assembly time, thereby improving production efficiency. Compared with gluing to the wire outlet of the switch box, the connecting wire structure using the wire clip connecting wire 200 makes the switch box 100 more tidy and beautiful as a whole.

[0026] Furthermore, the line card 220 and the connecting wire 210 are formed into an integral structure through an injection molding process, which ensures that there is no gap or looseness between the connecting wire 210 and the line card 220, so that the line card connecting wire 200 has integrity, and the length of the connecting wire 210 on both sides of the line card 220 can be adjusted to a standard length, which is conducive to the assembly of the line card connecting wire 200; the switch box 100 is provided with a circuit board 140, and one end of the connecting wire 210 located in the switch box 100 is connected to the circuit board 140, and the connecting wire 210 extends to the outside of the switch box 100. One end is connected to the range hood. Usually, both ends of the connecting wire 210 are provided with pins for connecting to the circuit board 140 or the range hood. When the switch box 100 is assembled, the wire card connecting wire 200 is fixed to the switch box 100 through the wire card 210 and connected to the circuit board 140 through one end extending to the inside of the connecting wire 210. Then, the assembly is completed after the face cover 110 is closed and fixed to the back cover 120. When the switch box 100 is assembled on the range hood, it only needs to be fixed to the corresponding position of the range hood and the connecting wire 210 extending outside is connected to the corresponding position of the range hood.

[0027] Furthermore, the card slot 130 is provided with a card plate 131, which extends vertically downward from the card slot 130, and the line card 220 is provided with a slot body 221 matching the card plate 131. The card plate 131 is embedded in the slot body 221 to fix the line card 220 on the card slot 130. The card plate 131 restricts the line card 220 from moving forward and backward after being installed in the card slot 130; the cover 110 is provided with a card protrusion 132 extending toward the card slot 130, and the card protrusion 132 is close to the side of the line card 220 away from the inside of the switch box 100 to restrict the line card 220 from moving up and down. In other embodiments, if the card slot 130 is provided on the cover 110, the card protrusion 132 should be correspondingly provided on the back cover 120; the card protrusion 132 and the card plate 131 are perpendicular to each other, and at the same time restrict the movement of the line card 220 to ensure that the line card 2 20 is fixed in the slot 130 to ensure stability and prevent the connecting line 210 from loosening; the card plate 131 is interference fit with the slot body 221, the two sides of the line card 220 are interference fit with the two sides of the card slot 130, the card protrusion 132 is interference fit with the line card 220, and the line card 200 forms interference fit with the slot 130 and the card plate 131 at multiple locations to ensure the sealing; fixing plates 150 are provided on both sides of the switch box 100, and fixing holes are provided on the fixing plates 150. The switch box 100 is conveniently installed on the range hood as a whole through the fixing plates 150 and the fixing holes. The switch box 100 is provided with a display control panel 160, and the display control panel 160 is provided with a display interface and buttons. After the switch box 100 is connected to the range hood, the operating status of the range hood is displayed through the display interface, and the operating status or switch of the range hood is controlled by buttons.
