Description

Technical Field

[0001] The present invention relates to the technical field of temperature sensors, and specifically to a dry-burning prevention temperature sensor and a manufacturing method thereof. Background Art

[0002] Temperature is a very crucial physical quantity for controlling the cooking of an intelligent rice cooker. The intelligent rice cooker can monitor the temperature, judge possible heating defects, and then promptly detect and handle them, prevent the occurrence of sticking to the pot phenomenon, and operate according to the pre-set temperature, thereby ensuring the cooking quality. And this process must be realized by combining a thermistor temperature sensor with a single-chip microcomputer for temperature acquisition. Then digital temperature conversion and output can be achieved; the inner pot presses on the top of the sensor, and the sensor will move downward, causing the ejector rod to push open the short-circuit piece to realize the heating of the heating plate. When the inner pot is removed, the sensor moves upward and the short-circuit piece leaves the ejector rod to realize the short circuit of the thermistor and make the heating plate not heat, achieving the dry-burning prevention effect;

[0003] The existing current temperature sensor devices for rice cookers / electric pressure cookers / electric stir-fry pans, etc. are composed of an axially glass-sealed thermistor plus an insulating sleeve. Since the insulating sleeve is adiabatic and there are gaps between the thermistor installed in the sleeve, the axially glass-sealed thermistor cannot be effectively tightly attached to the metal surface. Therefore, the current products have slow thermal response and poor thermal response consistency;

[0004] Moreover, since the axially glass-sealed thermistor and the axially two-pole wire connections to the wire are all naked, workers need to separately put insulating sleeves on their exposed parts, resulting in poor work efficiency and high labor costs;

[0005] In addition, since the axially glass-sealed thermistor and the two naked electrode wires axially connected to the wire connection terminals need to be manually sleeved with insulating sleeves and cannot be automatically produced, when fixing the thermistor with an insulating sleeve in the metal cover using the thermistor and the metal fixing bracket, it is easy to pierce the insulating sleeve, causing poor withstand voltage and leakage phenomenon.

By installing the thermistor 3 and the wire 5 in the through - groove 8, direct installation can be carried out without manually sleeving an insulating sleeve at the wire part, enabling automated production with high work efficiency and low cost. Moreover, since the insulating sleeve is cancelled, there will be no phenomenon of piercing through the insulating sleeve, resulting in poor withstand voltage and leakage. After cancelling the insulating sleeve, by setting the pressure silicone 16, the thermistor 3 can be effectively and tightly installed onto the metal cover 1, so the thermal response is fast and the thermal response consistency is good.

Moreover, the thermistor 3 and the wire 5 are both installed in the through groove 8, and can be directly installed without manually sleeving an insulating sleeve on the wire, enabling automated production and having a relatively high working efficiency.

[0052] Embodiment 4

[0053] Based on the above Embodiment 3, as Figures 4-8 shown, in step S4, a coating mechanism is used to coat glue on the heat-conducting ceramic sheet 2. The coating mechanism includes a U-shaped plate 28. A storage tank 18 is arranged on the U-shaped plate 28. A liquid outlet funnel 24 is fixedly arranged inside the U-shaped plate 28. A connecting pipe 29 is arranged on the storage tank 18, and the other end of the connecting pipe 29 penetrates and is connected to the liquid outlet funnel 24.

[0054] Among them, preferably, an installation block is fixedly arranged at the rear side of the liquid outlet funnel 24. A connecting rod is installed on the installation block. A driving motor is fixedly arranged at the upper end of the connecting rod. The front output end of the driving motor is fixedly connected to a rotating rod 46. A rotating disk 37 is fixedly connected to the front side of the rotating rod 46. A circular hole is formed in the rear side wall of the liquid outlet funnel 24, and the rotating disk 37 is rotatably connected in the circular hole. An extending rod 39 is fixedly arranged at an eccentric position at the front end of the rotating disk 37. A square frame 38 is arranged in cooperation with the extending rod 39. A moving rod 40 is fixedly arranged at the lower end of the square frame 38. A moving plate 19 is fixedly arranged on the lower side of the moving rod 40. The moving plate 19 is slidably connected to the inner wall of the liquid outlet funnel 24. The connection position of the connecting pipe 29 and the liquid outlet funnel 24 is located below the moving plate 19.

[0055] Among them, a conveyor belt 23 is arranged below the liquid outlet funnel 24, which can convey the heat-conducting ceramic sheet 2 to be coated with glue below the liquid outlet funnel 24.

[0056] The working principle and beneficial effects of the above technical solution are as follows: The storage tank 18 stores glue. The connecting pipe 29 conveys the glue in the storage tank 18 into the liquid outlet funnel 24, and the glue is only located below the moving plate 19. Start the driving motor. The driving motor drives the rotating rod 46 to rotate. The rotating rod 46 drives the rotating disk 37 to rotate. The rotating disk 37 drives the extending rod 39 to revolve around the center point of the rotating disk 37, so that the square frame 38 moves up and down. The square frame 38 drives the moving rod 40 to move up and down. The moving rod 40 drives the moving plate 19 to move up and down. When the moving plate 19 descends, it will squeeze out the glue in the liquid outlet funnel 24, which then falls onto the heat-conducting ceramic sheet 2. By adopting the above method, the extrusion operation of the glue can be completed quickly, with a simple structure and convenient use, effectively improving the practicability of the device.

[0057] Embodiment 5

[0058] Based on the above Embodiment 4, as Figures 4-10As shown in the figure, symmetrically arranged rack bars 27 are fixedly provided at the lower end of the moving plate 19.

[0061] The working principle and beneficial effects of the above technical solution are as follows: When the moving plate 19 moves up and down, the moving plate 19 drives the first gear 22 to rotate. The first gear 22 drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the blade 21 to rotate. The blade 21 will stir the glue liquid in the liquid outlet funnel 24, thereby reducing the possibility of the glue liquid solidifying; at the same time, the up and down movement of the moving plate 19 will drive the push rod 42 to move up and down. When the push rod 42 moves upward, it will push the push head 41 to move. The push head 41 drives the U-shaped knocking rod 20 to move. When the push rod 42 moves downward, the U-shaped knocking rod 20 is reset under the action of the return spring 43, and the knocking head 47 will knock on the liquid outlet funnel 24, thereby exhausting the liquid outlet funnel 24. The gas is discharged through the exhaust pipe, reducing the gas in the glue liquid, which can effectively improve the bonding effect of the glue liquid and has strong practicability.

[0062] Embodiment 6

[0063] On the basis of the above Embodiment 5, as Figures 4-10 shown in the figure, a sliding frame 44 is further provided on the rear side wall of the liquid outlet funnel 24. A sliding block 48 is fixedly provided on the sliding frame 44. The sliding block 48 is slidably arranged on the rear side wall of the liquid outlet funnel 24.

The semi-gear 49 alternately meshes with the upper and lower toothed plates 45. A limiting rod 30 is fixedly provided at the lower end of the sliding frame 44. A stopper 31 is fixedly provided at the lower end of the limiting rod 30.

[0064] Among them, preferably, a hollow cylinder 34 is fixedly arranged through the left vertical section of the U-shaped plate 28. A sliding plate 35 is slidably arranged in the hollow cylinder 34. One end of the sliding plate 35 away from the left vertical section of the U-shaped plate 28 is fixedly provided with a gas pushing rod 33. The gas pushing rod 33 slidably extends out of the hollow cylinder 34. The other end of the gas pushing rod 33 is fixedly connected with a matching plate 32. The matching plate 32 is fixedly arranged on the stopper 31. A pushing spring 36 is also sleeved on the gas pushing rod 33. One end of the pushing spring 36 is fixedly connected with the sliding plate 35, and the other end of the pushing spring 36 is fixedly connected with the inner wall of the hollow cylinder 34. An air pipe 25 is connected to the hollow cylinder 34. The other end of the air pipe 25 is connected to the liquid outlet funnel 24 in a penetrating manner, and the penetrating position of the air pipe 25 and the liquid outlet funnel 24 is below the moving plate 19.

[0065] Among them, an air inlet hole is arranged in the hollow cylinder 34, and one-way valves are arranged in both the air pipe 25 and the air inlet hole.

[0066] The working principle and beneficial effects of the above technical solution are as follows: After the driving motor is started, the rotating rod 46 starts to rotate. The rotating rod 46 drives the semi-gear 49 to rotate. The semi-gear 49 meshes with the two toothed plates 45 alternately, so that the sliding frame 44 moves left and right. The left and right movement of the sliding frame 44 will drive the limiting rod 30 to move left and right. The limiting rod 30 drives the stopper 31 to move left and right. When the moving plate 19 descends, the stopper 31 will leave the lower end of the liquid outlet funnel 24. When the moving plate 19 ascends, the stopper 31 just blocks the outlet end of the liquid outlet funnel 24. When the stopper 31 leaves the outlet end of the liquid outlet funnel 24, the stopper 31 pushes the matching plate 32 to move. The matching plate 32 drives the gas pushing rod 33 to move. The gas pushing rod 33 drives the sliding plate 35 to move. The sliding plate 35 will push the hollow cylinder 34 into the air pipe 25 and then into the liquid outlet funnel 24 to blow and stir the glue liquid in the liquid outlet funnel 24, further reducing the possibility of the glue liquid solidifying. At the same time, with the cooperation of the knocking head 47 and the exhaust pipe, the gas in the glue liquid can also be effectively discharged. When the stopper 31 blocks the outlet end of the liquid outlet funnel 24, the sliding plate 35 will reset under the action of the pushing spring 36, so that the hollow cylinder 34 is re-inflated.

[0067] Through the above structure, under the action of a driving motor, the extrusion of the glue liquid, the mechanical stirring of the glue liquid, the gas stirring of the glue liquid are realized, and at the same time the exhaust effect is realized. The structure has a high degree of cooperation and strong practicability.

[0068] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
