[0017] The following embodiments given in conjunction with the drawings further illustrate the specific embodiments of the present application. The present application is not limited to the descriptions of the following embodiments.

[0018] As Figure 1 shown, a UVC LED disinfection and sterilization module includes a water circulation device 1. A water storage chamber 12 is arranged in the middle of the water circulation device 1. A water inlet 13 and a water outlet 14 are arranged on the water circulation device 1, and the water inlet 13 and the water outlet 14 are respectively communicated with the water storage chamber 12; an LED module 2 is fixedly arranged on the outer periphery of the water circulation device 1. The LED module 2 is adjacent to the water storage chamber 12. A quartz panel 21 is fixedly arranged outside the LED module 2. The quartz panel 21 is pressed on the water circulation device 1 through a baffle 22. One side of the baffle 22 abuts against the quartz panel 21, and the baffle 22 is fixedly connected to the water circulation device 1 by screws; a wire groove 3 is arranged on the outer periphery of the water circulation device 1. The wire groove 3 is adjacent to the water storage chamber 12. The wire groove 3 shares a side wall with the water storage chamber 12. A detachable wire baffle 4 is fixedly arranged outside the wire groove 3. The connecting wire of the LED module 2 is located in the wire groove 3. Referring to the attached Figure 2 and 3 shown, the wire groove 3 and the LED module 2 surround the outer periphery of the water storage chamber 12, which is beneficial to taking away heat in time during the water circulation process. The overall structure layout of the UVC LED disinfection and sterilization module is compact and the volume is small, which is convenient to meet the sterilization requirements through the combination of UVC LED disinfection and sterilization modules according to the actual shape of the production line.

[0019] Referring to the attached Figure 1 and 3As shown, first, after the power supply is turned on, the initial set power of the UV LED lamp is 100%, the UVC intensity is 10 mm, and the disinfection and sterilization module of the UVC LED array combination (LED module 2) starts to work. Subsequently, it irradiates the target product through the irradiation window of the quartz panel 21. When the disinfection and sterilization module of the UVC LED array combination works, a large amount of heat is generated, thus enabling the water circulation system. Then, water enters through the water inlet 13, circulates in the entire system, and immediately takes away the heat generated by the disinfection and sterilization module of the UVC LED array combination. Finally, it exits from the water outlet 14. The inlet water temperature is not higher than 20 °C, and the outlet water temperature is generally within 45 °C, ensuring that the heat generated by the UVC LED can be taken away, so as to complete the internal integral water circulation system for disinfection and sterilization.

[0020] As Figure 1 shown, in one embodiment, an opening is provided in the upper part of the water storage chamber 12, and a sealing plate 15 is fixedly provided on the opening. The sealing plate 15 is fixedly connected to the water circulator 1 through locking screws.

[0021] As Figure 3 shown, in one embodiment, the water circulator 1 is a cuboid, and the LED module 2 and the wire groove 3 are respectively located on two adjacent side surfaces of the cuboid.

[0022] As Figure 1 shown, in one embodiment, a sealing groove 16 is provided on the side wall of the water circulator 1, a sealing ring is provided on the side wall of the sealing plate 15, and the sealing ring is located in the sealing groove 16.

[0023] In one embodiment, K-type thermocouples are embedded at the bottom of the LED circuit board in the LED module and in the water storage chamber.

[0024] Due to high-power UVC LEDs, heat dissipation plays a very crucial role. We embed K-type thermocouples at the bottom of the LED circuit board and in the water storage chamber to facilitate controlling the temperature of the LED circuit board. If the temperature of the LED circuit board is too high, we can increase the flow rate of the cooling water or confirm that the UVC LED is working properly.

[0025] As Figure 3 shown, in one embodiment, the water inlet 13 and the water outlet 14 are located on the opposite sides of the LED module 2. This further improves the rationality of the structural layout and facilitates the combined use of the modules.

[0026] During the use of the UVC LED disinfection and sterilization module, there is no thermal impact on the objects to be disinfected and sterilized, and the original properties of the materials are maintained. The water temperature over-temperature alarm device ensures sufficient heat dissipation of the LED to achieve the maximum luminous efficiency of the LED. Adjust the output UVC power to be suitable for the disinfection of packaging materials on production lines with different line speeds. It can meet the sterilization requirements through module combination according to the actual shape of the production line, and has a high sterilization efficiency. The optional quartz panel 21 with high-transmittance UV light can effectively reduce the entry of dust particles into the LED, facilitating maintenance and cleaning. This disinfection and sterilization module is Hg-Free, has a high safety level, and there is no risk of harming the human body. In addition, its UVC energy density is relatively high, capable of achieving second-level disinfection and sterilization. The overall body is made of lightweight aluminum parts, with low comprehensive energy consumption and convenient installation. It can be instantly turned on and reach the maximum UVC intensity value within seconds.

[0027] The above content is a further detailed description of the present application in combination with specific preferred implementation manners, and it cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present application.
