Description

Technical Field

[0001] This utility model relates to the technical field of electric blanket controller equipment, specifically an easy-to-operate electric blanket controller button. Background Technology

[0002] An electric blanket, also known as an electric mattress, is a contact-type electric heating appliance. It incorporates specially designed, high-insulation, flexible heating elements woven or sewn into the blanket in a serpentine pattern. When powered on, it emits heat, primarily used to raise the temperature inside the bedding for warmth during sleep. It can also be used to dehumidify bedding. It consumes little electricity, has adjustable temperature, is convenient to use, and is widely used, with a history of over 100 years. Currently, the "+" and "-" buttons on electric blanket controllers are often made of silicone if they are connected, and separate if plastic. Using silicone buttons is too expensive, while separate plastic buttons involve multiple assembly steps, making them less convenient.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an easy-to-operate electric heating controller button, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an easy-to-operate electric heating controller button, including a control base plate and a button cover, wherein the control base plate has a clip and a slot, and an upper cover lever connected to the control base plate is fixedly provided in the middle of the clip and the slot, and a horizontal groove is provided on the button cover, the size of the horizontal groove being the same as the size of the upper cover lever, the control base plate having a clip and a structure inside, and a limit groove being provided on the side wall of the button cover.

[0006] Preferably, the card and structure include a moving block, a spring, a stop block, a card and a block, and a slot is provided on the bottom surface of the control base plate. The slot is located inside the moving block, and the end of the moving block is inserted into the control base plate.

[0007] Preferably, one end of a spring is fixed on the inner wall of the control base plate, and the other end of the spring is fixedly connected to a clip and a block, the size of which is the same as the size of the limiting groove.

[0008] Preferably, the card and block are located outside the limiting groove, and the inner surface of the card and block abuts against the moving block.

[0009] Preferably, a transverse limiting groove is connected to the slot on the bottom surface of the control base plate, and a stop block is engaged in the slot, with a downwardly extending handle on the stop block.

[0010] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides an easy-to-operate electric heating controller button. By setting a top cover lever in the limiting groove on the control base plate, after assembly, the top cover bone contacts the bottom surface of the button groove. When "+" is pressed, the "-" end will lift up through the lever principle, so that the "-" end will not contact the PCB of the top cover and will not work, effectively controlling the cost. At the same time, the limiting structure can better fix the button cover. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the present invention; Figure 2 This is a cross-sectional view of the present invention; Figure 3 This is a top view schematic diagram of the present invention.

[0012] In the diagram: 1. Control base plate; 2. Button cover; 3. Limiting foot; 4. Top cover lever; 5. Clip and slot; 6. Moving block; 7. Spring; 8. Abutting block; 9. Clip and block; 10. Empty slot; 11. Limiting slot. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1-3 The diagram illustrates an easy-to-operate electric heating controller button, comprising a control base plate 1 and a button cover 2. The control base plate 1 has a latch and slot 5. A top cover lever 4, connecting the control base plate 1, is fixedly positioned between the latch and slot 5. The button cover 2 has a horizontal groove, the same size as the top cover lever 4. The control base plate 1 contains a latch and slot structure. A limiting groove 11 is formed on the side wall of the button cover 2. When the button cover 2 is inserted into the latch and slot 5, the horizontal groove on the button cover 2 presses against the top cover lever 4, and the top cover rib of the button cover 2 contacts the bottom surface of the button slot. When the "+" key is pressed, the "-" end tilts upwards due to the lever principle, preventing it from contacting the PCB of the top cover and thus preventing operation. Similarly, when the "-" key is pressed, the "+" end tilts upwards and also prevents contact with the PCB of the top cover, preventing operation. This allows the "+" and "-" keys on the integrated button cover 2 to operate independently.

[0015] The card and structure include a moving block 6, a spring 7, a stop block 8, a card and block 9. A slot 10 is provided on the bottom surface of the control base plate 1. The slot 10 is located inside the moving block 6. The end of the moving block 6 is inserted into the control base plate 1.

[0016] The working principle of this device and its mechanism is as follows: After inserting the button cover 2 into the limiting groove 5, lift the moving block 6 upwards. At this time, the spring 7 relaxes, pushing the card and block 9 forward into the limiting groove 11. This completes the fixing of the button cover 2. Under normal circumstances, it is not necessary to disassemble the button cover 2. If disassembly is required, first insert the abutment block 8 into the empty groove 10. Since the empty groove 10 is through and the moving block 6 itself has a certain degree of flexibility, when the abutment block 8 pushes the button cover 2 upwards, the moving block 6 will disengage from the limiting groove 11. At this time, the abutment block 8 abuts the card and block 9. Then, move the abutment block 8 outwards to move the card and block 9 until the spring 7 retracts and the card and block 9 return to their original positions. Then, insert the moving block 6 to lock the card and block 9.

[0017] One end of a spring 7 is fixed on the inner wall of the control base plate 1, and the other end of the spring 7 is fixedly connected to a clip and a block 9. The size of the clip and the block 9 is the same as the size of the limiting groove 11, so that the clip and the block 9 can be embedded in the limiting groove 11 to fix and limit the button cover 2.

[0018] Card and block 9 are located outside the limiting groove 11, and the inner side of card and block 9 abuts against moving block 6.

[0019] A horizontal limiting groove is connected to the slot 10 on the bottom surface of the control base plate 1, which allows the abutment 8 to move laterally within the limiting groove, thereby pushing the card and block 9 back to their original positions. The height of the abutment 8 when inserted to the bottom is lower than the top of the card and block 9, so there will be no collision with the abutment 8 when the moving block 6 is inserted. At the same time, the length of the horizontal limiting groove extends to the position of the moving block 6 corresponding to the bottom surface of the control base plate 1. The abutment 8 is locked in the slot 10. The abutment 8 is provided with a downwardly extending handle, which makes it easy for a person to pull and remove the abutment 8. After the button cover 2 is disassembled and the card and block 9 are limited, the abutment 8 can be removed.

[0020] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
