The light source assembly 300 can emit sterilizing light and discharge ozone generated by the ozone generating device for sterilizing the weighing objects on the weighing platform 110. Specifically, the light source assembly 300 may emit an irradiation light having a sterilization function, so as to sterilize the weighed object on the weighing platform 110; meanwhile, the light source assembly 300 may discharge ozone generated by the ozone generating device transmitted through the connection pipe 220, so as to sterilize the weighing object on the weighing platform 110 with ozone. Therefore, the weighing objects on the weighing platform 110 can be subjected to double disinfection of sterilization light and ozone, and multi-angle full-coverage disinfection of the weighing objects can be realized.

When the sterilizing electronic scale is used, a weighing object is placed on the weighing platform 110, the weighing object is measured by the weighing object of the scale main body 100, and after the sterilizing lamp device 200 receives a weighing signal, the sterilizing function is started after a certain time delay. That is, on the one hand, the ozone generating device is started to generate ozone, and the ozone is transmitted to the light source assembly 300 through the connecting pipe 220 and is discharged to the surface of the weighing object by the light source assembly 300, so that the ozone on the surface of the symmetrical weight is eliminated.

Thus, the ozone and sterilization light dual sterilization of the symmetrical heavy objects is realized through the connecting pipe 220, and the sterilization effect of the symmetrical heavy objects is ensured.

According to one technical scheme, an ozone generating device is arranged in a control box 210 of the killing electronic scale to generate ozone, the ozone is transmitted to a light source assembly 300 through a hose in a connecting pipe 220, and the ozone is discharged to the surface of a weighing object on a weighing table 110 through the light source assembly 300, so that ozone killing is performed on the weighing object. Meanwhile, the terminal line in the connection pipe 220 controls the opening of the light source assembly 300, so that the light source assembly 300 emits the irradiation light with the sterilization function, and the sterilization light is irradiated on the surface of the weighing object, and the light sterilization is performed by the symmetrical weight. Therefore, on the one hand, the double killing modes of ozone killing and light killing of the symmetrical heavy objects are realized through the connecting pipe 220, and the killing effect of the symmetrical heavy objects is ensured. On the other hand, the killing electronic scale disclosed by the utility model can complete killing while weighing the symmetrical weight, is simple and quick in killing mode, and avoids complicated killing means. On the other hand, the microorganism bacteria, viruses and parasites on the weighing objects are prevented from being brought into the home, and the transmission path of the microorganism bacteria, viruses and parasites through the weighing objects is cut off. On the other hand, the weighing is carried out while the symmetrical weights are used for killing, the peculiar smell of market berths such as fruits and vegetables is removed, and the cleanliness of the market berths is improved.

Further, in order to facilitate the fixed connection between the scale main body 100 and the sterilizing lamp device 200, the scale main body 100 further includes a scale base 120, the scale base 120 is provided with a weighing platform 110, the control box 210 is provided with a connecting plate 211, and the connecting plate 211 is fixed at the bottom of the scale base 120, so that the sterilizing lamp device 200 is fixedly connected with the scale main body 100. Specifically, the connection plate 211 fixes the killing lamp device 200 and the scale main body 100 at the same time by screws, and then connects two signal lines of the sensor of the scale main body 100 to the main control board in the control box 210 of the killing lamp device 200. In one embodiment, by setting the main control board program, after the main control board MCU chip receives the sensor signal of the scale main body 100, the switch of the light source assembly 300 and the switch of the ozone generating device are triggered after a delay of 1S, so as to emit sterilizing light and ozone gas, thereby sterilizing the heavy objects at multiple angles. In another embodiment, when the scale body 100 uses an external 220V power source, a DC power can be connected to the power source of the scale body 100 to the main control board in the control box 210 of the sterilizing lamp device 200 instead of the battery. Thus, the scale body 100 and the killing lamp device 200 are fixedly connected through the connection plate 211, and the structural stability of the killing electronic scale is ensured to prevent the killing electronic scale from toppling over. Meanwhile, the sterilizing lamp device 200 is connected to the scale body 100, and a power source shared by the sterilizing lamp device 200 and the scale body 100 can be realized by introducing a sensor signal of the scale body 100 into the sterilizing lamp device 200.

Further, the light source assembly 300 includes a ring-shaped light source base 310, and the light source base 310 is connected with the connection tube 220 by a connection rod 311.

In one embodiment, the LED lamp beads 321 are UVC-LED lamp beads with wavelength of 220 and 280nm, and the dominant wavelength is UVC-LED lamp beads with wavelength of 254 nm. That is, LED lamp pearl 321 can send shortwave sterilization ultraviolet ray, and light source subassembly 300 adopts shortwave ultraviolet irradiation to disinfect, and its wavelength is shorter, and the energy is higher, can be absorbed by ozone. In some embodiments, the LED beads 321 are uniformly spaced along the circumference of the light source substrate 320, so that the uniformity of the sterilization light emitted by the light source assembly 300 can be ensured, the sterilization uniformity of the symmetric weight can be improved, and the sterilization effect of the symmetric weight can be ensured. In one embodiment, the light source substrate 320 is an aluminum-based PCB with a thickness of 1.0 ± 0.2mm, and the UVC-LED lamp beads are welded on the aluminum-based PCB by an SMT mounter. In this example, the symmetric heavy object is killed with ozone, which is caused to penetrate into the interior of the bacterial cell by reacting with the double bond of the lipid of the bacterial cell wall, and acts on protein and lipopolysaccharide to change the permeability of the cell, thereby causing cell death. Meanwhile, the ozone can also remove peculiar smell, and mainly utilizes the oxidation principle that the ozone is used as a strong oxidant, and the ozone can generate chemical reaction with the peculiar smell of amine, hydrogen sulfide, methyl mercaptan and the like, so that the ozone is oxidized and decomposed to generate nontoxic and tasteless gas. The symmetrical weight is sterilized by ultraviolet ray, which can destroy the molecular structure of DNA and RNA in microbe and virus to kill growing cell and regenerating cell. Meanwhile, the ultraviolet cleaning technology is also utilized to remove the organic pollutants on the surface of the weighing object, thereby achieving the purpose of sterilization. In addition, the plants can also absorb carbon dioxide generated in the ultraviolet tube cleaning process and convert the carbon dioxide into oxygen. Therefore, the double sterilization of ozone and ultraviolet is carried out through the symmetrical heavy objects, so that on one hand, microorganisms, bacteria, viruses and parasites are prevented from being brought into home; on the other hand, the weighing is carried out while sterilization and disinfection are carried out, so that the peculiar smell of market pavements such as fruits, vegetables, aquatic products and the like is removed; on the other hand, except for the closed regular weighing, ozone plays a role in killing when the irregular weighing object shields ultraviolet light, so that the weighing can be realized while the symmetrical weight can be killed in a multi-angle and full-coverage manner; on the other hand, the fruits and vegetables are subjected to secondary photosynthesis under the action of ultraviolet rays, the organic matter content of the fruits and vegetables is improved in the process of converting light energy into chemical energy, and the fruits and vegetables are preserved by killing microorganism bacteria such as penicillium, green mold and aspergillus which can cause the fruits and vegetables to rot and deteriorate.
