Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to a disinfection device. Background Technology

[0002] In the field of household appliance disinfection cabinets, pulsed light disinfection is widely used in the disinfection equipment market due to its advantages such as strong penetration, thorough disinfection, and short disinfection time. Pulsed light disinfection uses inert gas lamps such as xenon, which are excited by a power unit to output pulsed intense light. It can emit a spectrum with wavelengths in the range of 200 nanometers to 1000 nanometers, a spectrum close to that of natural light, covering the full spectrum from ultraviolet to infrared, but with much greater intensity than natural light. Different wavelengths of the pulsed light spectrum have different disinfection effects. For example, ultraviolet disinfection uses ultraviolet light to destroy the molecular structure of microbial cells to achieve sterilization, while infrared disinfection uses infrared radiation to raise the temperature and kill bacteria, viruses, and other microorganisms through high-temperature heating. Therefore, full-spectrum pulsed light has a unique photothermal synergistic effect. However, for some situations where only a single disinfection need is required, such as when only ultraviolet disinfection is needed (tableware is not heat-resistant, or strict requirements are placed on the disinfection time), or when only infrared disinfection is applicable (where strict restrictions on chemical contamination are required), the application of pulsed light disinfection equipment is limited and its versatility is poor. Utility Model Content

[0003] The purpose of this invention is to provide a disinfection device that can solve the problem that existing pulsed light disinfection equipment is limited in application and has poor versatility when it is only suitable for a single disinfection need.

The disinfection device further includes a pulsed light generator and a filter element disposed within the disinfection chamber. The pulsed light generator is capable of emitting pulsed light and has an outlet facing the disinfection chamber. The filter element includes at least two filters, which are capable of filtering light of different wavelengths respectively. The filter element is movably connected to the housing, and any one of the at least two filters can selectively cover the outlet.

[0006] In one embodiment, the filter element also has a light-transmitting opening, and at least two of the filters and the light-transmitting opening are arranged in sequence, with one of the at least two filters and the light-transmitting opening able to cover the light-emitting opening.

[0007] In one embodiment, the filter is located in front of the light outlet along the light emission direction, and the disinfection device further includes a driving assembly for driving the filter to move in a plane parallel to the light outlet, so that one of the at least two filters blocks the light outlet.

[0008] In one embodiment, the drive assembly includes a drive motor and a drive gear. The drive motor is connected to the housing, and the output end of the drive motor is connected to the drive gear. The filter element is provided with a transmission gear set, and the drive gear meshes with the transmission gear set.

[0009] In one embodiment, the filter element is parallel to the light outlet, and the transmission gear assembly includes a plurality of transmission straight teeth arranged sequentially along the moving direction of the filter element.

[0010] In one embodiment, the drive assembly further includes a driven gear and a drive shaft, the filter includes two sets of drive gears spaced apart along a direction perpendicular to the movement direction of the filter, the driven gear and the driving gear respectively mesh with the two sets of drive gears, one end of the drive shaft is connected to the driving gear, and the other end is connected to the driven gear.

[0011] In one embodiment, along the moving direction of the filter element, at least two of the filters and the transmission gear set are spaced apart at both ends of the filter element, and the transmission shaft is located beside the filters.

[0012] In one embodiment, the disinfection device further includes a display control component, which includes an operation display screen disposed on the outside of the housing. The operation display screen is used to display the working modes of the disinfection device. The disinfection device has multiple working modes, with at least two working modes corresponding to at least two filters.

[0013] In one embodiment, the display control component is communicatively connected to the pulsed light generator and the filter, and the display control component is capable of controlling the operation of the pulsed light generator and / or the filter; and / or,

[0014] The disinfection device further includes a temperature sensor and / or an ultraviolet sensor disposed in the disinfection chamber. The temperature sensor is used to detect the temperature in the disinfection chamber, and the ultraviolet sensor is used to detect the ultraviolet intensity in the disinfection chamber. The temperature sensor and the ultraviolet sensor are communicatively connected to the display control component.

[0015] In one embodiment, the pulsed light generator includes a lamp tube and a reflector covering the lamp tube, with the light outlet located on the reflector; and / or,

[0016] The enclosure includes multiple side panels, which are interconnected and surround to form the disinfection chamber. One of the side panels includes a partition and a back panel spaced apart, forming a receiving cavity between the partition and the back panel. The partition has a connecting opening that connects the receiving cavity and the disinfection chamber. The pulse light generator is disposed within the receiving cavity, and the light output port and the connecting opening at least partially overlap. The filter is movably disposed on the partition.

[0017] The beneficial effects of this utility model are:

[0018] The disinfection device provided by this utility model includes a pulsed light generator and a filter element disposed within a disinfection chamber. The pulsed light generator emits pulsed light covering a spectrum with wavelengths from 200 nanometers to 1000 nanometers. The pulsed light generator has an outlet facing the disinfection chamber. The pulsed light enters the disinfection chamber through the outlet, putting the disinfection device into pulsed light disinfection mode, disinfecting the items to be disinfected using full-spectrum light waves. The filter element includes at least two filters, each capable of filtering light of different wavelengths. The filter element is movably connected to the housing, and any one of the filters can selectively cover the outlet. The filters achieve spectral separation, intercepting light waves within a certain wavelength range. For example, ultraviolet (UV) filters allow only UV light with wavelengths from 10 nm to 400 nm to pass through. The UV light entering the disinfection chamber disinfects the parts to be disinfected, putting the disinfection device in UV disinfection mode. This is suitable for parts that can only be disinfected with UV light. Infrared filters, on the other hand, allow only infrared light with wavelengths from 760 nm to 1 mm to pass through. The emitted infrared light raises the temperature inside the disinfection chamber, putting the disinfection device in infrared drying mode and drying the parts at high temperatures. This is suitable for parts that require only high-temperature infrared disinfection. Therefore, by using different filters to allow light of different wavelengths to pass through, different disinfection methods can be achieved, giving the disinfection device different disinfection modes to meet various disinfection needs, expanding its application range, and improving its versatility.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the field of household appliance disinfection cabinets, pulsed light disinfection is widely used in the disinfection equipment market due to its advantages such as strong penetration, thorough disinfection, and short disinfection time. Pulsed light disinfection uses inert gas lamps such as xenon, which are excited by a power unit to output pulsed light. It can emit a spectrum with wavelengths in the range of 200 nanometers to 1000 nanometers, a spectrum close to that of natural light, covering the full spectrum from ultraviolet to infrared, but with much greater intensity than natural light. Different wavelengths of the pulsed light spectrum have different disinfection effects. For example, ultraviolet disinfection uses ultraviolet light to destroy the molecular structure of microbial cells to achieve sterilization, while infrared disinfection uses infrared radiation to raise the temperature and kill bacteria, viruses, and other microorganisms through high-temperature heating. Therefore, full-spectrum pulsed light has a unique photothermal synergistic effect. However, for some situations where only a single disinfection need is required, such as when only ultraviolet disinfection is needed (tableware is not heat-resistant, or strict requirements are placed on the disinfection time), or when only infrared disinfection is applicable (where strict restrictions on chemical contamination are required), the application of pulsed light disinfection equipment is limited and its versatility is poor.

[0036] To solve the above problems, such as Figures 1 to 10 As shown, this embodiment provides a disinfection device, which includes a housing 1 with a disinfection chamber 11. The disinfection device also includes a pulsed light generator 2 and a filter 3 disposed within the disinfection chamber 11. The pulsed light generator 2 emits pulsed light covering a spectrum of wavelengths from 200 nm to 1000 nm. The pulsed light generator 2 has an outlet 21 facing the disinfection chamber 11. The pulsed light enters the disinfection chamber 11 through the outlet 21, putting the disinfection device into a pulsed light disinfection mode, disinfecting the items to be disinfected using full-spectrum light waves. The filter 3 includes at least two filters 31, each capable of filtering light of different wavelengths. The filter 3 is movably connected to the housing 1, and any one of the filters 31 can selectively cover the outlet 21. The filters 31 achieve spectral separation, intercepting light waves with wavelengths within a certain range. For example, the ultraviolet filter 311 only allows ultraviolet light with wavelengths from 10 nanometers to 400 nanometers to pass through. The ultraviolet light entering the disinfection chamber 11 disinfects the parts to be disinfected, putting the disinfection device in ultraviolet disinfection mode. This is suitable for parts that are only suitable for ultraviolet disinfection. The infrared filter 312 only allows infrared light with wavelengths from 760 nanometers to 1 millimeter to pass through. The emitted infrared light raises the temperature inside the disinfection chamber 11, putting the disinfection device in infrared drying mode, where the parts to be disinfected are dried at high temperature. This is suitable for parts that are only disinfected using high-temperature infrared disinfection. Therefore, by using different filters 31 to transmit light of different wavelengths, different disinfection methods are achieved, giving the disinfection device different disinfection modes to meet various disinfection needs, expanding its application range, and improving its versatility.

[0037] The principle and specific structure of the pulse light generator 2 that emits pulse light can be referred to the existing technology for equipment, which is not the focus of this application, and this embodiment is not limited here.

[0038] In one embodiment, such as Figure 2 As shown, the filter element 3 also has a light-transmitting port 32. At least two filters 31 and the light-transmitting port 32 are arranged sequentially, and one of the filters 31 and the light-transmitting port 32 can cover the light-emitting port 21. The filter element 3 moves, allowing different filters 31 or light-transmitting ports 32 to cover the light-emitting port 21, thus switching the disinfection mode. When the light-transmitting port 32 covers the light-emitting port 21, the light-transmitting port 32 is directly connected to the light-emitting port 21, without blocking the pulsed light, and the disinfection device is in pulsed light disinfection mode. For example, the filter element 3 includes an ultraviolet filter 311 and an infrared filter 312, which are located on opposite sides of the light-transmitting port 32. Thus, when switching disinfection modes is required in the pulsed light disinfection mode most frequently used by the disinfection device, the filter element 3 can move and quickly change the position of the ultraviolet filter 311 and the infrared filter 312 relative to the light-emitting port 21.

[0039] Along the light emission direction, the filter 3 is located in front of the light outlet 21, and the filter 3 forms a planar structure. For example... Figure 4 As shown, the disinfection device also includes a drive assembly 4, which drives the filter element 3 to move in a plane parallel to the light outlet 21, so that one of the at least two filters 31 blocks the light outlet 21. For example, when the ultraviolet filter 311 and the infrared filter 312 are located on opposite sides of the light-transmitting port 32, in the pulsed light disinfection mode, the drive assembly 4 only needs to operate once when the disinfection mode needs to be switched.

[0040] Specifically, the drive assembly 4 includes a drive motor (not shown in the figure) and a drive gear 41. The drive motor is connected to the housing 1, and the output end of the drive motor is connected to the drive gear 41. The filter element 3 is provided with a transmission gear set 42, and the drive gear 41 meshes with the transmission gear set 42. The drive motor drives the drive gear 41 to rotate, and then the drive gear 41 drives the transmission gear set 42 to move, thereby realizing the movement of the filter element 3.

[0041] The filter element 3 is parallel to the light outlet 21. In order to realize the translational movement of the filter element 3, the transmission gear group 42 includes a plurality of transmission straight teeth arranged sequentially along the moving direction of the filter element 3.

[0042] To improve the smoothness of the movement of the filter element 3, the drive assembly 4 also includes a driven gear 43 and a transmission shaft 44, such as Figure 8As shown, the filter element 3 includes two sets of transmission gears 42 spaced apart along a direction perpendicular to the movement direction of the filter element 3. A driven gear 43 and a driving gear 41 mesh with the two sets of transmission gears 42 respectively. One end of the transmission shaft 44 is connected to the driving gear 41, and the other end is connected to the driven gear 43. Driven by the drive motor, the driving gear 41 drives the driven gear 43 to rotate via the transmission shaft 44. The driven gear 43 and the driving gear 41 simultaneously drive the two sets of transmission gears 42 to move, making the movement support of the filter element 3 more reliable.

[0043] Along the moving direction of the filter element 3, at least two filters 31 and a transmission gear set 42 are spaced apart at both ends of the filter element 3, so that the two ends of the filter element 3 move synchronously, reducing the possibility of skewing during the movement of the filter element 3. The transmission shaft 44 is located beside the filter element 3. Exemplarily, in one embodiment, the ultraviolet filter 311, the light-transmitting port 32, and the infrared filter 312 are arranged vertically along the height direction of the disinfection chamber 11, and the filter element 3 moves vertically; the transmission shaft 44 is located below the filter 31 to avoid obstructing the filter 31. When the disinfection device switches working modes, the drive assembly 4 is activated to move the filter element 3 vertically. Figure 4 and Figure 5 As shown, the light-transmitting port 32 is connected to the light-emitting port 21, and the disinfection device is in pulsed light disinfection mode; as Figure 6 As shown, the ultraviolet filter 311 covers the light outlet 21, and the disinfection device is in ultraviolet disinfection mode; Figure 7 As shown, the infrared filter 312 covers the light outlet 21, and the disinfection device is in the external drying mode.

[0044] In another embodiment, the ultraviolet filter 311, the light-transmitting port 32, and the infrared filter 312 are arranged left and right along the width direction of the disinfection chamber 11. The filter element 3 moves left and right, and the drive shaft 44 is located on the right or left side of the filter 31 to avoid blocking the filter 31.

[0045] The disinfection device also includes a display and control component, which includes an operation display screen 5. The operation display screen 5 is located on the outside of the housing 1 and is used to display the operating modes of the disinfection device. The disinfection device has multiple operating modes, with at least two operating modes corresponding to at least two filters 31. In one embodiment, for easier observation by the operator, the operation display screen 5 is located on the cabinet door of the housing 1. Figure 2As shown, the filter element 3 has an ultraviolet filter 311, a light-transmitting port 32, and an infrared filter 312. Correspondingly, the disinfection device has an ultraviolet disinfection mode, a pulsed light disinfection mode, and an infrared drying mode. To make the working modes more intuitive, the cabinet door has a transparent viewing area, through which the color of the light inside the disinfection chamber 11 can be seen. In the ultraviolet disinfection mode, the light emitted through the ultraviolet filter 311 is purple; in the infrared drying mode, the light emitted through the infrared filter 312 is red; and in the pulsed light disinfection mode, the light emitted through the light-transmitting port 32 is white.

[0046] The disinfection device also includes a temperature sensor 6 and / or an ultraviolet sensor 7 disposed within the disinfection chamber 11. The temperature sensor 6 detects the temperature within the disinfection chamber 11, and the ultraviolet sensor 7 detects the ultraviolet intensity within the disinfection chamber 11. The temperature sensor 6 and the ultraviolet sensor 7 are communicatively connected to the display and control components. The ultraviolet sensor 7 monitors the ultraviolet intensity within the disinfection chamber 11 in real time to further monitor the disinfection effect; the temperature sensor 6 monitors the temperature within the disinfection chamber 11 to further monitor the drying effect. When the ultraviolet intensity or drying temperature deviates significantly from its respective set value, the display and control components adjust the operating parameters of the disinfection device. Simultaneously, through changes in emitted light color and sensor quantization, the disinfection and drying processes are visualized and quantifiable under control.

[0047] The display control component is communicatively connected to the pulse light generator 2 and the filter 3, and can control the operation of the pulse light generator 2 and / or the filter 3. Specifically, the operation display screen 5 has a temperature / time display area 51, a temperature / time setting button 52, an ultraviolet display area 53, an ultraviolet setting button 54, and a one-button start button 55. The temperature / time display area 51 can display the temperature and working time inside the disinfection chamber 11 in real time, the ultraviolet display area 53 can display the ultraviolet intensity inside the disinfection chamber 11 in real time, the temperature / time setting button 52 and the ultraviolet setting button 54 can switch between ultraviolet disinfection mode and infrared drying mode, and when switching modes, the infrared target temperature, target working time or target ultraviolet intensity can be set with one button; the one-button start button 55 can start the pulse light disinfection mode, in which the pulse light performs disinfection and drying simultaneously according to a fixed program.

[0048] like Figure 9 As shown, the pulsed light generator 2 includes a lamp tube 22 and a reflector 23 covering the lamp tube 22, with a light outlet 21 opened on the reflector 23. The reflector 23 reflects the light, allowing as much light as possible to be emitted through the light outlet 21, thus avoiding energy waste.

[0049] In addition to the cabinet door, the cabinet body 1 also includes multiple side panels 12, which are interconnected and enclose a disinfection chamber 11. One of the side panels 12 is used to install a pulsed light generator 2. To ensure that light can illuminate the entire space of the disinfection chamber 11, the side panel 12 corresponding to the cabinet door is used to install the pulsed light generator 2 and a filter 3. The side panel 12 includes a partition 121 and a back panel 122 spaced apart, forming a receiving cavity 123 between the partition 121 and the back panel 122. The partition 121 has a connecting opening 124, which connects the receiving cavity 123 and the disinfection chamber 11. The pulsed light generator 2 and the driving assembly 4 are disposed within the receiving cavity 123. The light outlet 21 and the connecting opening 124 at least partially overlap. The filter 3 is movably disposed on the partition 121. The filter 3 is fitted against the partition 121 and located within the receiving cavity 123. The side plate 12 can protect the pulse light generator 2 and the filter 3, reducing the probability of damage.

[0050] like Figure 1 As shown, the chamber also has at least one shelf 13 for holding items to be sterilized. The shelf 13 is usually made of stainless steel wire mesh, which allows pulsed light, ultraviolet light and infrared light to pass through and fill the entire sterilization chamber 11.

[0051] This embodiment also provides a method for using the disinfection device, as detailed below:

[0052] This disinfection device has three working modes: pulsed light disinfection mode, ultraviolet disinfection mode, and infrared drying mode. After the disinfection device is powered on, press the one-button start button 55. The pulsed light generator 2 is powered on, and the filter element 3 is in the initial state. In the initial state, the light-transmitting port 32 corresponds to the light-emitting port 21. The preset running time M is displayed on the operation display screen 5, which shows the temperature inside the disinfection chamber 11, the ultraviolet intensity, and the remaining running time in real time. After the running time is over, the pulsed light disinfection mode program ends.

[0053] When the ultraviolet disinfection mode is selected, the target ultraviolet intensity Z is first input on the operation display screen 5. The pulse light generator 2 is started, the input power is increased, and the filter element 3 moves to the position where the ultraviolet filter 311 covers the light outlet 21. The ultraviolet light passes through the filter element 3 and emits purple light. The ultraviolet sensor 7 detects the ultraviolet intensity K in real time. When the ultraviolet intensity K is less than the target ultraviolet intensity Z, the display control component controls the pulse light generator 2 to increase the input power until the ultraviolet intensity K is greater than or equal to the target ultraviolet intensity Z. The pulse light generator 2 runs continuously at this power for a preset time M. The operation display screen 5 displays the real-time ultraviolet intensity and the remaining running time. When the running time is completed, the pulse light generator 2 is powered off, the filter element 3 moves to the initial state, and the ultraviolet disinfection mode program ends.

[0054] When selecting the infrared drying mode, first input the target temperature value T on the operation display screen 5. The pulse light generator 2 starts, the input power increases, and the filter element 3 moves to the position where the infrared filter 312 covers the light outlet 21. Infrared light passes through the filter element 3 and emits red light. The temperature sensor 6 detects the temperature W inside the disinfection chamber 11 in real time. When the temperature W is less than the target temperature value T, the display control component controls the pulse light generator 2 to increase the input power until the temperature W is greater than or equal to the target temperature value T. The pulse light generator 2 runs continuously at this power for a preset time M. The operation display screen 5 displays the temperature inside the disinfection chamber 11 and the remaining running time. When the running time is completed, the pulse light generator 2 is powered off, the filter element 3 moves to the initial state, and the infrared drying mode program ends.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
