DETAILED DESCRIPTION

[0033] The specific implementation of the utility model is described in further detail below in conjunction with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0034] As Figures 1 to 6 Indicated, the utility model embodiment provides infrared response sterilization and disinfection device based on deep ultraviolet LED, it includes shell 1 and battery box 2, shell 1 is the open top surface less than the open bottom surface hollow inverted U type structure, shell 1 with battery box 2 detachable connection, shell 1's left and right side and rear side are installed at least one deep ultraviolet LED lamp pearl 4, the ultraviolet light that deep ultraviolet LED lamp pearl 4 emits is obliquely downward irradiation to shell 1, shell 1's left and right side is installed at least one infrared transmitting tube 5 and at least one infrared receiving tube 9 respectively, shell 1 is installed with sterilization control circuit board 12 in it;

[0035] Sterilization control circuit board 12 includes power supply module, control and timing module, infrared sensor module and LED constant current drive module, the power input end of power supply module is electrically connected with the power output end of battery box 2, the power output end of power supply module is electrically connected with the power input end of control and timing module and LED constant current drive module, the signal input end of infrared sensor module is electrically connected with infrared receiving tube 9, the signal output end of infrared sensor module is electrically connected with the signal input end of control and timing module, the signal output end of control and timing module is electrically connected with the signal input end of LED constant current drive module, the signal output end of LED constant current drive module is electrically connected with deep ultraviolet LED lamp pearl 4.

[0036] Specifically, the shell 1 is arranged as a hollow inverted U-shaped structure with a top opening smaller than a bottom opening, so as to facilitate the user to put the articles to be sterilized into the sterilization device from the front side of the shell 1, avoiding the user to perform the cumbersome operation of opening and closing the cover; meanwhile, the design of the top opening smaller than the bottom opening can also prevent the ultraviolet light from being irradiated from the top of the sterilization device. The shell 1 is made of 6061 aluminum material and is processed by CNC (Computerized Numerical Control) process and anodic oxidation. The deep ultraviolet LED lamp bead 4 adopts a third-generation semiconductor UVC-LED light source with a wavelength of 265-280 nm and a voltage of 5.0-6.5 V, which can break the DNA or RNA gene chain of bacteria or viruses, so as to make them unable to replicate or lose activity, thereby achieving the purpose of sterilization and disinfection. The at least one infrared emitting tube 5 and the at least one infrared receiving tube 9 are arranged horizontally above the corresponding deep ultraviolet LED lamp bead 4, and the deep ultraviolet LED lamp bead 4 is arranged in a certain inclined angle matrix. The infrared emitting tube 5 is used for emitting infrared light, and the infrared receiving tube 9 is used for receiving the infrared light emitted by the infrared emitting tube 5. Under normal circumstances, the infrared emitting tube 5 emits infrared light, and the infrared receiving tube 9 receives the infrared light. When a hand or other objects block the infrared light path, the infrared receiving tube 9 cannot receive the infrared signal, at which time the infrared receiving tube 9 feeds back a signal to the sterilization control circuit board 12, so that the sterilization control circuit board 12 acts. The power supply module is used for supplying power to the entire sterilization control circuit board 12. The timing time of the control and timing module can be 15 s, 20 s, 25 s, etc.

[0037] When the sterilization device is used, it is first placed horizontally on the desktop, and after the battery box 2 is electrically connected with the shell 1, the sterilization device enters the working mode. When the user places the articles to be sterilized such as mobile phones in the sterilization device, the infrared light emitted by the infrared emitting tube 5 is instantaneously blocked by the hand or arm, resulting in that the infrared receiving tube 9 cannot receive the infrared signal. At this time, the infrared receiving tube 9 feeds back the sensing signal to the infrared sensor module, and the infrared sensor module sends the sensing signal to the control and timing module. The control and timing module controls the sterilization device to enter the sterilization mode according to the sensing signal, specifically, the control and timing module controls the LED constant current driving module to act, so as to drive the deep ultraviolet LED lamp bead 4 to emit ultraviolet light to sterilize the articles to be sterilized. At the same time, the control and timing module controls the time, so as to control the time of the deep ultraviolet LED lamp bead 4 to emit ultraviolet light. When the timing time is reached, the control and timing module controls the LED constant current driving module to stop driving the deep ultraviolet LED lamp bead 4 to emit ultraviolet light. Thus, the sterilization of the articles is completed, and the user can take out the sterilized articles from the shell 1.

[0038] It should be noted that, in order to ensure that the user's hand or arm has enough time to withdraw from the housing 1, the control and timing module can delay for a specified period of time before controlling the LED constant current drive module to drive the deep ultraviolet LED beads 4 to emit ultraviolet light.

[0039] Furthermore, when the sterilized items are removed from the sterilization device, the infrared emitter 5 is momentarily blocked by a hand or arm. This change is detected by the infrared receiver 9, which generates a signal and sends it to the infrared sensor module. The infrared sensor module then transmits the signal to the control and timing module, which, based on the signal, re-enters the sterilization device into sterilization mode. Therefore, the entire process sterilizes both the items and the area where the items were placed, resulting in more thorough sterilization.

[0040] like Figures 7 to 10 The diagram shows the circuit schematics of the power supply module, control and timing module, infrared sensor module, and LED constant current drive module.
