[0028] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.
[0029] See also Figure 1-5As shown, the technical solution adopted in this specific embodiment is: a noodle cooker heating controller, including a rear panel 5, a single-chip control board 6 is fixedly arranged on the surface of the rear panel 5, and the rear panel 5 is also penetrated by an electrical port 3 electrically connected to the single-chip control board 6, and the single-chip control board 6 is provided with an adjustment device 65 electrically connected to the single-chip control board 6, and the adjustment device 65 includes a rotating shaft 651 made of stainless steel and a photoelectric detector 653 sleeved on the outer wall of the end of the rotating shaft 651, the photoelectric detector 653 is fixedly arranged on the single-chip control board 6 and electrically connected to the single-chip control board 6, the outer wall of the rotating shaft 651 is slidably sleeved with a support bracket 655 fixedly connected to the bottom of the photoelectric detector 653, and the photoelectric detector 653 is fixedly sleeved on the outer wall of the rotating shaft 651. The detector 653 includes a photoelectric counter-radiation sensor 22 fixedly connected to the support bracket 655 at the bottom and a code disk 21 sleeved on the outer wall of the end of the rotating shaft 651. The photoelectric counter-radiation sensor 22 is provided with a plurality of gratings 23. In this embodiment, two gratings are provided. The photoelectric counter-radiation sensor 22 is also provided with a signal output port 24. The photoelectric counter-radiation sensor 22 is electrically connected to the single-chip control board 6 through the signal output port 24. A lubricant groove 12 is provided on the outer wall of the middle section of the rotating shaft 651. The lubricant groove 12 is filled with lubricant. When the rotating shaft 651 is rotated, the lubricant in the lubricant groove 12 reduces the friction generated when the rotating shaft 651 rotates, thereby reducing the wear of the rotating shaft 651. When in use, the power supply is connected through the power port 3, and the connection The electrical port 3 is a 220VAC-380VAC adaptive interface, which transmits current to the single-chip control board 6 to power it. The single-chip control board 6 is provided with a single-chip microcomputer and a thyristor. The thyristor enables the single-chip control board 6 to control the heating tube power of the noodle cooker connected thereto. At the same time, the rotating shaft 651 of the adjustment device 65 is rotated to generate an electrical signal for the photoelectric detector 653 at its end. When the rotating shaft 651 rotates, the code disk 21 of the photoelectric detector 653 rotates at the same time. Since the code disk 21 is provided with saw teeth, the grating 23 is periodically shielded during the rotation process, thereby generating a pulse signal that is received by the photoelectric counter-radiation sensor 22, and then the photoelectric counter-radiation sensor 22 outputs the electrical signal from the signal output port 24 to The single-chip microcomputer control board 6, when controlling, there is no contact between the grating 23 and the code disk 21, and thus no friction loss is generated, and the service life is greatly improved. The electrical signal is output to the single-chip microcomputer control board 6 to control the output power. When the rotating shaft 651 is rotated, a lubricant groove 12 is provided in the middle section, and the lubricant groove 12 is filled with lubricant, so that after the controller is fully loaded, the friction between the rotating shaft 651 and other components during the rotation process is greatly reduced. At the same time, the rotating shaft 651 made of stainless steel has higher wear resistance and strength, reducing the possibility of bending and deformation due to external force, and thus it is not easy to wear after long-term use, avoiding the phenomenon of uneven rotation caused by wear, and making the rotation angle easier to control;
[0030] The single-chip control board 6 is further provided with a front panel 2 on the side away from the rear panel 5, and the rotating shaft 651 penetrates the front panel 2. The front panel 2 is made of stainless steel, which is conducive to supporting the adjustment device 65 and preventing debris from entering from the front during use to affect the normal operation of the single-chip control board 6;
[0031] The front panel 2 is also sealed with an outer shell 1 covering the single-chip control board 6. The outer surface of the outer shell 1 is provided with a plurality of protrusions and is made of aluminum material, which is conducive to shielding the single-chip control board 6 and reducing the impact of the external environment on its operation. At the same time, it is made of aluminum and provided with a plurality of protrusions to better dissipate heat;
[0032] The rear panel 5 is also provided with a water level switch interface 4, which is conducive to installing a water level detector through the water level switch interface 4 and electrically connecting it to the single-chip control board 6, so that when the water level of the pot on the noodle cooker is detected to be too low, the heating is turned off and an alarm is sounded;
[0033] The front end of the rotating shaft 651 is also provided with a front panel knob 63, which is conducive to making the twisting of the rotating shaft 651 more convenient and labor-saving, and is waterproof and oil-proof;
[0034] The single-chip control board 6 is also fixed with a display screen 64 penetrating the front panel 2, which is conducive to monitoring the operating status of the device;
[0035] The outer wall of the rotating shaft 651 is provided with a buffer gasket 15 between the support bracket 655 and the photoelectric detector 653. When the rotating shaft 651 is subjected to axial pressure during transportation or use, the rotating shaft 651 will be pressed internally and move along the pressure direction, causing the space between the support bracket 655 and the photoelectric detector 653 to be compressed, thereby causing the buffer gasket 15 to be squeezed and deformed and absorb the pressure, thereby preventing the rotating shaft 651 from being further pressed internally and being able to recover through the elastic force of the buffer gasket 15 after the pressure disappears, thereby preventing the adjusting device from being damaged due to collision during transportation or use;
[0036] The upper and lower surfaces of the buffer gasket 15 are provided with clips 18 sleeved on the outer wall of the rotating shaft 651, which is conducive to making the buffer gasket 15 more evenly stressed and avoiding skewing and deformation;
[0037] A safety latch 16 is detachably provided on the rotating shaft 651 between the buffer pad 15 and the photoelectric detector 653 to prevent the matching parts from being separated from the rotating shaft 651;
[0038] An isolation plate 17 is provided on the outer wall of the rotating shaft 651, and a sealing ring 13 is provided on the outer wall of the rotating shaft 651 between the isolation plate 17 and the lubricant groove 12. This is beneficial for preventing the front panel knob 63 from being over-pressed during installation through the isolation plate 17, and preventing foreign debris from contacting the lubricant groove 12. At the same time, the sealing ring 13 cooperates with the lubricant in the lubricant groove 12 to prevent it from leaking out.
[0039] Working principle of the utility model: When the utility model is used, the power supply is connected through the power port 3, and the power port 3 is a 220VAC-380VAC adaptive interface, and then the current is transmitted to the single-chip control board 6 to power it on. The single-chip control board 6 is provided with a single-chip microcomputer and a thyristor. The single-chip control board 6 can control the heating tube power of the noodle cooker connected thereto through the thyristor. At the same time, the rotating shaft 651 of the adjustment device 65 can be rotated to make the photoelectric detector 653 at the end generate an electrical signal. When the rotating shaft 651 rotates, the code disk 21 of the photoelectric detector 653 rotates at the same time. Since the code disk 21 is provided with saw teeth, the grating 23 will be periodically shielded during the rotation process, thereby generating a pulse signal that is detected by the photoelectric detector. The photoelectric sensor 22 receives the signal, and then outputs the electrical signal from the signal output port 24 to the single-chip control board 6 through the photoelectric counter-radiation sensor 22. During control, there is no contact between the grating 23 and the code disk 21, and no friction loss is generated, and the service life is greatly improved. The electrical signal is output to the single-chip control board 6 to control the output power. When the rotating shaft 651 is rotated, a lubricant groove 12 is provided in the middle section, and the lubricant groove 12 is filled with lubricant. Therefore, after the controller is fully loaded, the friction between the rotating shaft 651 and other components during the rotation process is greatly reduced, and it is not easy to wear after long-term use, avoiding the rotation smoothness caused by wear, and making the rotation angle easier to control.
