Description

Technical Field

[0001] The present invention relates to the technical field of microbial detection equipment for food, and specifically to a microbial detection device based on a photoelectric sensor. Background Art

[0002] To ensure food safety, it is often necessary to conduct microbial detection on the produced food, and thus microbial detection equipment for food is required. The invention patent with the patent application number CN202311464428.7 discloses a food microbial detection device. Through the adjustment of the rotating shaft of the motor, while adjusting the feeding speed of food raw materials, the spraying of nutrients into the detection cylinder can be controlled. When the motor speed increases, the feeding speed of food raw materials increases, and at the same time, the spraying speed of nutrients into the detection cylinder synchronously increases. At the same time, driven by the linkage component, the spraying rates of nutrients in the two detection cylinders on both sides change synchronously. Control the first electric telescopic rod to shorten, so that the lower gear disk disengages from the upper gear disk, and then the stirring mechanism stops rotating. Start the motor, and the motor drives the detection cylinder to rotate, which can facilitate the observation of the detection results in the detection cylinder through the observation mirror. According to the disclosed technical solution, when the existing food microbial detection equipment is in use, on the one hand, to ensure food detection efficiency, it is often necessary to use a transmission device to convey the food to be detected, which is likely to interfere with food detection due to the bacteria growing on the transmission device. On the other hand, when the equipment is working, it is prone to heat generation, which is not conducive to ensuring work safety, and at the same time, it cannot adjust the heat dissipation speed in real time according to the heat generation situation. On the third hand, during the detection work, it is easy for dust in the air and the bacteria carried by the dust to fall on the food, which is not conducive to ensuring the reliability of the food detection results.

The detection circuit is connected to the display screen through a wire. The first button and the second button are connected to the first fan through wires.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the microbial detection device based on the photoelectric sensor is in use, the motor drives the belt to move through the roller, and the food to be detected is placed on the belt one by one, so that the belt conveys the food into the box body one by one, improving the detection efficiency. After the food on the belt is sent out, the second fan blows the filtered air into the inner side of the support box through the air duct. When the air flows to the right, it pushes the movable plate. The movable plate approaches the bottom of the belt under the extrusion of the spring, thereby generating a strong air flow at the bottom of the belt. The strong air flow is used to blow off the food residues attached to the belt, and at the same time, it is blocked by the partition net and collected at the bottom of the support box to avoid the scattering of debris, effectively cleaning the belt and ensuring the environmental hygiene of the surrounding area. The second disinfection lamp disinfects the belt, and at the same time, the second fan cools down the belt, which can not only avoid the interference of bacteria on the belt on the microbial detection of food, but also avoid the killing effect of the high temperature of the belt on the microorganisms on the food.

[0015] 2. When the microbial detection device based on a photoelectric sensor detects microorganisms on food, the photoelectric sensor emits a light beam towards the target. When the emitted light beam encounters microorganisms, the light beam will be scattered or absorbed by the microorganisms, resulting in a change in the optical signal. The optical signal is converted into an electrical signal, and these electrical signals are then sent to the detection circuit for processing. Noise and interference are filtered out, useful signals are extracted, and they are converted into control signals or data outputs and displayed through a display, thereby realizing the detection of microorganisms. The heat generated by the operation of the photoelectric sensor is conducted to the inner side of the inner box, and then to the inner side of the guide sleeve, causing the air in the guide sleeve to expand and push the piston to the right. The piston first presses Button 2, and Button 2 first turns on Fan 1 located at the bottom of the box body. Fan 1 generates suction on the left side of the box body through the outlet, causing air to enter the inner side of the filter cartridge through the inlet, then pass through the filter screen and enter the bottom of the inner box through the connecting pipe, then flow to the top of the left side of the box body through the upper opening, and then be blown downward by Fan 1. When the temperature of the photoelectric sensor continues to rise, the air in the guide sleeve will continue to expand, further pushing the piston to the right. The piston presses Button 2 to compress the spring and until it presses Button 1. Button 1 turns on Fan 1 in the outlet on the left side of the box body. The two Fans 1 carry out ventilation and heat dissipation work simultaneously, and can adjust the heat dissipation air volume in real time according to the heat generation condition of the detection device, which can not only ensure the heat dissipation effect on the photoelectric sensor, but also save heat dissipation energy consumption.

[0016] 3. When the microbial detection device based on a photoelectric sensor dissipates heat from the photoelectric sensor, after air enters the inner side of the box body through the upper opening, the air flows along the intervals of the partition plate in the upper left of the box body, causing the air to flow back and forth on the left side of the box body until the air flows out through the two outlets. The disinfection lamp 1 disinfects and sterilizes the air, and uses the air to flow back and forth under the guidance of the partition plate to increase the disinfection time and effect of the air. A part of the air flow flows downward to the bottom of the box body, and then the sterile air flows outwards at the bottom of the box body, thereby generating a sterile space at the bottom of the box body. Dust and bacteria in the external air cannot enter the inner side of the box body. At the same time, the air flows to both sides at the bottom of the box body, forming an isolation effect on the top of the belt, preventing dust and bacteria in the air from falling on the food, and effectively preventing bacteria in the air from contaminating the food, ensuring the reliability of the microbial detection of the food.

After the food on the belt 5 is sent out, the second blower 26 blows the filtered air into the inner side of the support box 1 through the air duct 25. When the air flows to the right, it pushes the movable plate 28. The movable plate 28 approaches the bottom of the belt 5 under the extrusion of the spring 24, thereby generating a strong air flow at the bottom of the belt 5.

When cooling the photoelectric sensor 8, after air enters the inside of the box body 6 through the upper opening 15, the air flows along the intervals of the partitions 16 in the upper left of the box body 6, so that the air flows back and forth on the left side of the box body 6 until the air flows out through the two outlets 18. The first disinfection lamp 17 disinfects and sterilizes the air, and uses the air to flow back and forth under the guidance of the partitions 16 to increase the disinfection time and effect of the air.

When detecting the microorganisms on the food, the photoelectric sensor 8 emits a light beam towards the target. When the emitted light beam encounters microorganisms, the light beam will be scattered or absorbed by the microorganisms, resulting in a change in the optical signal. The optical signal is converted into an electrical signal, and these electrical signals are then sent to the detection circuit for processing, filtering out noise and interference, extracting useful signals, and converting them into control signals or data outputs, and being displayed through the display 9, so as to realize the detection of microorganisms. The heat generated by the operation of the photoelectric sensor 8 is conducted to the inner side of the inner box 7, and then to the inner side of the guide sleeve 20, causing the air in the guide sleeve 20 to expand, pushing the piston 21 to the right. The piston 21 first presses the button two 23, and the button two 23 first turns on the fan one 19 located at the bottom of the box body 6. The fan one 19 generates suction on the left side of the box body 6 through the outlet 18, causing air to enter the inner side of the filter cartridge 11 through the inlet 12, being filtered by the filter screen 13 and then entering the bottom of the inner box 7 through the connecting pipe 14, flowing to the top of the left side of the box body 6 through the upper opening 15, and then being blown downward by the fan one 19.

When in use, the motor 3 drives the belt 5 to move through the roller 4, and the food to be detected is placed on the belt 5 one by one, so that the belt 5 conveys the food into the box body 6 one by one, improving the detection efficiency. After the food on the belt 5 is sent out, the second blower 26 blows the filtered air into the inner side of the support box 1 through the air duct 25. When the air flows to the right, it pushes the movable plate 28. The movable plate 28 approaches the bottom of the belt 5 under the extrusion of the spring 24, thereby generating a strong air flow at the bottom of the belt 5. The strong air flow is used to blow off the food residues attached to the belt 5. At the same time, the partition net 29 is used for blocking and collecting them at the bottom of the support box 1 to avoid the scattering of debris, effectively cleaning the belt 5 and ensuring the environmental hygiene around. The second disinfection lamp 27 disinfects the belt, and at the same time, the second blower 26 cools down the belt 5. This can not only prevent the bacteria on the belt 5 from interfering with the microbial detection of food, but also prevent the high temperature of the belt 5 from killing the microorganisms on the food. When detecting the microorganisms on the food, the photoelectric sensor 8 emits a beam of light towards the target. When the emitted beam of light encounters microorganisms, the beam of light will be scattered or absorbed by the microorganisms, resulting in a change in the optical signal. The optical signal is converted into an electrical signal, and these electrical signals are then sent to the detection circuit for processing, filtering out noise and interference, extracting useful signals, and converting them into control signals or data outputs, and displayed through the display 9, thereby realizing the detection of microorganisms. The heat generated by the operation of the photoelectric sensor 8 is conducted to the inner side of the inner box 7, and then to the inner side of the guide sleeve 20, causing the air in the guide sleeve 20 to expand, pushing the piston 21 to the right. The piston 21 first presses the second button 23, and the second button 23 first turns on the first blower 19 located at the bottom of the box body 6.

When the temperature of the photoelectric sensor 8 continues to rise, the air in the guide sleeve 20 will continue to expand, further pushing the piston 21 to the right. The piston 21 presses the second button 23 to compress the spring 24 until it presses the first button 22.

A part of the air flow flows downward to the bottom of the box body 6, so that the sterile air flows outward at the bottom of the box body 6, and then a sterile space is generated at the bottom of the box body 6. Dust and bacteria in the outside air cannot enter the inside of the box body 6. At the same time, the air flows to both sides at the bottom of the box body 6, forming an isolation effect on the top of the belt 5, preventing dust and bacteria in the air from falling onto the food, and effectively avoiding the contamination of the food by bacteria in the air, thus ensuring the reliability of the microbial detection of the food.
