Description

UVC LED sterilizing equipment

Technical Field

The invention relates to the technical field of sterilization, in particular to UVC LED sterilization equipment.

Background

At present, it has become a generally accepted practice to sterilize viruses and bacteria with Ultraviolet rays, i.e., Ultraviolet Germicidal Irradiation of UVGI (Ultraviolet sterilization). Ultraviolet sterilization irradiation UVGI destroys nucleic acid of microorganisms such as viruses and bacteria mainly by short-wave ultraviolet UVC (ultraviolet radiation), thereby further destroying DNA thereof so that it cannot perform important cell functions to achieve an effect of killing or inactivating, wherein the wavelength of the short-wave ultraviolet is 200 nm-280 nm.

With the outbreak of the novel coronavirus, the test paper for detecting the novel coronavirus on the surface of the imported packaging material is positive, and people have increasing worry about the virus on the surface of the product packaging material. Due to the advantages of strong inactivation effect of ultraviolet sterilization irradiation UVGI on microorganisms such as viruses and bacteria, short time consumption, no damage to hosts and the like, the ultraviolet sterilization irradiation UVGI has been widely applied to water disinfection, air disinfection, medical sanitation and aseptic workplaces, equipment on the market is mainly used in families and medical fields, and the industrial field of large-scale disinfection is less.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic diagram of a UVC LED sterilization apparatus according to an embodiment of the present invention.

As shown in fig. 1, the UVC LED germicidal device according to an embodiment of the present invention may include: a transmission motor 10, a transmission belt 20, a disinfection bin 30 and a transmission shaft 40.

The transmission motor 10 is used for controlling the transmission shaft 40 to rotate so as to drive the transmission belt 20 to move. The disinfection bin 30 is a cavity, the transmission belt 20 penetrates through the cavity, and the inner wall of the cavity is provided with a UVC LED used for irradiating the objects to be disinfected on the transmission belt 20 by a light source.

In some embodiments of the present invention, the cavity of the sterilization chamber 30 is an annular cavity, and the conveyor belt 20 extends through the annular cavity along a center line of the annular cavity.

It should be noted that the disinfection chamber 30 may be an annular cavity, or may be a cavity of other shapes, for example, an oval shape, a rectangular shape, etc., as long as the disinfection chamber can perform 360 ° overall irradiation on the article to be disinfected on the conveyor belt. Compared with cavities with other shapes, when the UVC LEDs are arranged, the same UVC LEDs can be used, and the irradiation intensity of the light source is ensured to be the same. Of course, when other shapes are used, the type of UVC LED used is determined according to the distance between the cavity and the conveyor belt to ensure the same intensity of light source illumination. For convenience of illustration, the following embodiments are illustrated with an annular cavity as an example.

In order to ensure the sterilization effect, in an embodiment of the present invention, the conveyor 20 may be a transparent conveyor, so as to ensure that when the article to be sterilized is in the sterilization chamber, the UVC LEDs correspondingly disposed on the inner wall of the sterilization chamber below the conveyor can also realize light source irradiation, so as to achieve 360 ° overall irradiation without dead angle on the article to be sterilized, and ensure that the article coming out from the sterilization chamber does not carry viruses and bacteria.

In one embodiment of the invention, the UVC LEDs are arranged in a plurality of ways, and may be separately arranged on the inner wall of the disinfection cabin, or may be integrated into a module, and then the module is arranged on the inner wall of the disinfection cabin.

As an example of the present invention, UVC LEDs may be disposed on an inner wall of the annular cavity in an array arrangement, as shown in fig. 2. That is to say, use single UVC LED to constitute an array, evenly place at the annular cavity inner wall, like this in the process of waiting to disinfect article through disinfecting the storehouse, every UVC LED can all realize waiting to disinfect the disinfection function of disinfecting article. The UVC LEDs may be uniformly arranged on the inner wall of the annular cavity, as shown in fig. 3, or may be arranged in a staggered manner, as shown in fig. 4, where fig. 3 and 4 show cross-sectional flat views of the annular cavity, and the square boxes show the UVC LEDs.

As another example of the present invention, as shown in fig. 5 and 6, a plurality of UVC LEDs are integrally disposed in one lens, and a plurality of lenses are disposed on an inner wall of an annular cavity. That is, in order to provide a higher radiation amount, a plurality of UVC LEDs may be integrally disposed in one lens, and a plurality of lenses may be disposed on the inner wall of the annular cavity. In fig. 6, three UVC LEDs are integrated, a convex lens is used as a reflection light source, and the specific number of the integrated UVC LEDs is set according to actual requirements. It should be noted that the focal length of the lens is smaller than the distance between the lens and the object to be sterilized, i.e. the object to be sterilized is located at the right side of the focal length.

In order to avoid the contact of the disinfected objects, in one embodiment of the present invention, the UVC LED disinfection apparatus further includes: and the mechanical arm is used for grabbing the objects to be disinfected and placing the objects to be disinfected on the conveying belt 20. The hypothesis disinfects the express delivery, place the express delivery in the assigned position, the arm is according to preset's route, snatch the express delivery of treating disinfection from the assigned position, and will treat that sterile express delivery is placed on the conveyer belt, along with the removal of conveyer belt, will treat that sterile express delivery moves to the disinfection storehouse in, the back that the disinfection finishes, in order to prevent that the express delivery after the disinfection is contaminated once more, can use another arm to snatch the express delivery after the disinfection to the assigned position.

It should be noted that the conveying belt may be in a conveying state all the time, or may move when an object to be sterilized is detected, for example, the conveying belt may be detected by a weight sensor, and when a change in weight is detected, a control signal is sent to the transmission motor, the transmission motor starts to operate, and the transmission shaft is controlled to start to rotate, so as to drive the conveying belt to move.

In addition, in the process of moving the objects to be disinfected, whether the objects to be disinfected move into the disinfection bin or not can be judged according to the moving distance, when the objects to be disinfected move into the disinfection bin, the transmission motor stops working, the objects to be disinfected stay in the disinfection bin, and when the disinfection time reaches the set time, the transmission motor starts working. Certainly, enough UVC LEDs are arranged in the disinfection cabin, so that when the disinfection of the to-be-disinfected articles can be finished without stopping, the transmission motor can control the transmission shaft to rotate according to the preset speed, and the transmission belt is driven to move.

In summary, according to the UVC LED sterilization apparatus provided by the embodiment of the present invention, the transmission motor controls the transmission shaft to rotate, so that the transmission belt passes through the sterilization chamber of the cavity, and the UVC LED disposed on the inner wall of the cavity performs 360 ° UVC light source irradiation on the article to be sterilized, thereby achieving the effect of killing viruses and bacteria, and meeting the increasing sterilization requirements.
