[0031] Embodiment 1

[0032] Figure 1 The schematic diagram of the structure of the range hood with nuclear radiation monitoring provided by the first embodiment of the utility model is shown. For the convenience of description, only the part related to the first embodiment of the utility model is shown;

[0033] In detail, in the first embodiment of the present invention, the range hood with nuclear radiation monitoring may at least include a range hood body 1, a nuclear radiation detection device 2, a distance sensor 3, a control device 6 located inside the range hood body 1, and a power supply 7;

[0034] The nuclear radiation detection device 2 is used to detect a first nuclear radiation intensity of the food 4 located on the table 5;

[0035] The distance measuring sensor 3 is used to measure the distance to the food 4;

[0036] The control device 6 is used to obtain the first nuclear radiation intensity of the food 4 and the distance between the ranging sensor 3 and the food 4, and to correct the first nuclear radiation intensity of the food 4 based on the distance between the ranging sensor 3 and the food 4 to obtain the second nuclear radiation intensity of the food 4;

[0037] The power supply 7 is used to supply power to the nuclear radiation detection device 2, the distance sensor 3 and the control device 6;

[0038] like Figure 1 As shown, the nuclear radiation detection device 2 is located on the range hood surface of the range hood body 1 , and the range hood surface is opposite to the table top 5 on which food 4 is placed; the distance measuring sensor 3 is arranged adjacent to the nuclear radiation detection device 2 .

[0039] Figure 2 The schematic diagram of the structure of the nuclear radiation monitoring system in the range hood with nuclear radiation monitoring provided by the first embodiment of the utility model is shown. For the convenience of description, only the part related to the first embodiment of the utility model is shown;

[0040] In the first embodiment of the present utility model, the nuclear radiation detection device 2 may include a nuclear radiation detector 22, a driving module 21 and a signal processing module 23;

[0041] The nuclear radiation detector 22 is used to detect the nuclear radiation level of the food 4;

[0042] The driving module 21 is used to provide voltage to the nuclear radiation detector 22 to drive the nuclear radiation detector 22 to work;

[0043] The signal processing module 23 is used to analyze and process the signal generated by the nuclear radiation detector 22; the signal processing module 23 may include an amplifier unit, a pulse shaping unit, a counting unit, etc.

[0044] In the first embodiment of the present invention, the control device 6 is connected to the nuclear radiation detection device 2 and the distance sensor 3 respectively.

[0045] In the first embodiment of the present invention, the nuclear radiation detector 22 is connected to the control device 6 via the signal processing module 23 .

[0046] In the first embodiment of the present invention, the nuclear radiation detector 22 can be a Geiger-Mueller counter; a Geiger-Mueller counter is a counting instrument for detecting the intensity of ionizing radiation (α particles, β particles, γ rays and X-rays). The principle is that when a certain ray particle enters the tube, it ionizes the gas in the tube, and the generated electrons are accelerated in the electric field with increasing energy. When the electrons collide with the gas molecules in the tube, they ionize the gas molecules again to generate electrons... In this way, a ray particle can generate a large number of electrons after entering the tube. These electrons reach the anode and the cations reach the cathode, generating a pulse discharge in the external circuit. The number of discharges can be recorded using electronic instruments. The Geiger-Müller counter is mainly composed of a hollow metal cylinder and a metal wire. The metal wire is electrically insulated from the metal cylinder and parallel to its axis. The metal cylinder is filled with low-pressure argon gas of about 50 Torr (about 1 / 15 of atmospheric pressure). An appropriate potential difference is added between the metal cylinder and the metal wire, so that the metal wire is at a higher potential than the metal cylinder, but still insufficient to discharge the argon gas. At this time, if particles or other rays enter through a very thin window, the argon gas in the metal cylinder will be ionized, and the freed electrons will be attracted by the positively charged metal wire. When the electron accelerates toward the metal wire, it will collide with other argon atoms and knock out more electrons, thus generating more electrons moving toward the metal wire and generating a very short pulse current. After passing through an appropriate amplification device, these pulse currents can produce a clicking sound or drive the counter to calculate the number of radiation particles entering the metal cylinder.

[0047] In the first embodiment of the present invention, the control device 6 is a microcontroller unit (MCU) or a system on chip (SOC).

[0048] In the first embodiment of the present utility model, the power supply 7 is connected to the nuclear radiation detection device 2, the distance sensor 3 and the control device 6 respectively;

[0049] In the first embodiment of the utility model, the power source 7 is connected to the nuclear radiation detector 22 through the driving module 21;

[0050] In the first embodiment of the present invention, when the nuclear radiation detector 22 is a Geiger-Mueller counter, the driving module 21 may be a high-voltage driving circuit, through which the power supply voltage may be transformed to provide a suitable operating voltage for the Geiger-Mueller counter, which is usually about 400V;

[0051] In the first embodiment of the present invention, the power supply 7 can be connected to the distance measuring sensor 3 through a power conversion module, and the power supply voltage can be converted through the power conversion module to provide a suitable working voltage for the distance measuring sensor 3.

[0052] In the first embodiment of the present utility model, the distance measuring sensor 3 may be a time of flight (ToF) sensor or other distance measuring sensors;

[0053] In the first embodiment of the utility model, a camera may be further provided on the range hood surface of the range hood body 1, through which the position of the food 4 can be determined, and then the distance between the food 4 and the distance measuring sensor 3 can be measured in combination with the distance measuring sensor 3, so that the distance value measured by the distance measuring sensor 3 is more accurate.

[0054] In the first embodiment of the present invention, the target to be detected, i.e., food 4, is placed on a table 5, which is opposite to the surface of the range hood provided with a nuclear radiation detection device 2 and a distance sensor 3, and the nuclear radiation detection device 2 is adjacent to the distance sensor 3. The nuclear radiation ray particles carried by the food 4 are detected by the nuclear radiation detection device 2, and a first nuclear radiation intensity value of the food 4 is obtained, and the nuclear radiation detection device 2 sends the first nuclear radiation intensity value to the control device 6. At the same time, the distance sensor 3 measures the distance value between it and the food 4 and sends the distance value to the control device 6. After the control device 6 obtains the first nuclear radiation intensity value and the distance value of the food 4, based on the distance value, by querying the relationship table between the nuclear radiation intensity and the distance or substituting it into a pre-established mathematical expression between the nuclear radiation intensity and the distance, the first nuclear radiation intensity value of the food 4 is corrected to obtain a second nuclear radiation intensity value of the food 4, which is the nuclear radiation detection result of the food 4 detected by the range hood with nuclear radiation monitoring in the embodiment of the present invention. The first embodiment of the utility model integrates a nuclear radiation detection device on the range hood, and the user only needs to place the food on the table below the range hood to detect the nuclear radiation level of the food, thereby improving the convenience of food nuclear radiation detection; and the nuclear radiation data detected by the nuclear radiation detection device is corrected by a ranging sensor, thereby improving the accuracy of food nuclear radiation detection.
