Description

Technical Field

[0001] This invention belongs to the field of ultraviolet disinfection technology, and specifically relates to an ultraviolet disinfection device with a grid rotating disc. Background Technology

[0002] Modern urban life places higher demands on personal and household hygiene. Everyday personal items, such as mobile phone surfaces, easily carry large amounts of bacteria and viruses. Viruses can also survive for up to 24 hours on cardboard. In addition to disinfecting personal items, people are increasingly demanding higher air quality in their homes and living spaces, necessitating indoor air disinfection. Aerosols (such as PM2.5 dust) are important carriers of airborne bacteria and viruses; for example, influenza viruses and COVID-19 can survive in airborne aerosols for up to 3 hours. Therefore, simultaneous disinfection of items and indoor air has become a pressing need. Existing... In the field of technology, ultraviolet sterilization products are usually single-function. To meet the dual needs of sterilizing personal items and indoor air, users can only purchase products with separate functions. Moreover, the sterilization process is relatively simple and there are cases of insufficient sterilization. Some sterilizers for sterilizing dishes, tableware, and other items increase airflow in the sterilization chamber by setting ventilation holes in the shell to facilitate the rapid drying of dishes, tableware, and other items. However, the tray used to place dishes and tableware not only blocks ultraviolet radiation, which is not conducive to the sterilization of the bottom of dishes and tableware, but also obstructs airflow, which is not conducive to the rapid drying of the bottom of dishes and tableware. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, one object of the present invention is to provide an ultraviolet sterilizer with a grid turntable.

[0005] To achieve the above objectives, according to the technical solution of the present invention, an ultraviolet sterilizer with a grid turntable is proposed, comprising: a housing assembly, the housing assembly including a first housing and a second housing hinged to each other, the first housing and the second housing defining a sterilization chamber for placing items to be sterilized, the bottom of the second housing having a first vent communicating the sterilization chamber with the outside atmosphere; an ultraviolet component, at least one ultraviolet component disposed on the bottom wall of the second housing, the ultraviolet component emitting ultraviolet light into the sterilization chamber; a turntable located above the ultraviolet component, and rotatably disposed on the bottom wall of the second housing, the turntable having multiple through holes, making the turntable grid-like; a second vent communicating the sterilization chamber with the outside atmosphere at the top of the first housing or the second housing; and an air pump disposed at the first vent and / or the second vent.

[0006] According to the ultraviolet sterilizer with a grid turntable proposed in this invention, a first housing and a second housing are hinged together, and a sterilization chamber is defined by the first housing and the second housing. The sterilization chamber can be opened or closed by rotating the first housing relative to the second housing, so as to facilitate the placement of items to be sterilized into the sterilization chamber or the removal of sterilized items from the sterilization chamber. The bottom of the second housing is provided with a first vent communicating between the sterilization chamber and the outside atmosphere, so that air in the sterilization chamber can flow out through the first vent, or outside air can flow into the sterilization chamber through the first vent. Ultraviolet rays emitted by the ultraviolet component can penetrate into the sterilization chamber to sterilize the items to be sterilized placed in the sterilization chamber and the air in the sterilization chamber. Specifically, at least one ultraviolet component is provided on the bottom wall of the second housing, so that the ultraviolet rays emitted by the ultraviolet component irradiate upward from the bottom of the sterilization chamber. Further, a turntable is provided above the ultraviolet component, and the turntable is used to place the items to be sterilized. Specifically, the turntable is provided with multiple through holes, so that the turntable is grid-shaped, allowing air to pass through. Both ultraviolet light and other ultraviolet rays can pass through the holes on the turntable. On the one hand, this facilitates the disinfection of the bottom of the items placed on the turntable; on the other hand, the air passing through the holes on the turntable can carry away the moisture from the bottom of the items to be disinfected, thus promoting the evaporation of moisture from the bottom of the items to be disinfected. The top of the first or second housing is provided with a second vent that connects the disinfection chamber to the outside atmosphere. An air pump is installed in the first vent and / or the second vent, thereby driving outside air to enter the bottom of the disinfection chamber from the first vent, pass through the holes on the turntable, pass through the items to be disinfected placed on the turntable, and then exit from the second vent, thus accelerating the evaporation of moisture from the items to be disinfected. Understandably, if the items to be disinfected are damp items such as bowls, plates, and tableware, the technical solution proposed in this invention can not only disinfect the bottom of the bowls, plates, and tableware, reducing dead corners of the items to be disinfected, but also make the moisture on the bottom and other parts of the bowls, plates, and tableware evaporate quickly, thus facilitating the rapid drying of all parts of the bowls, plates, and tableware.

[0007] It should be emphasized that the air in the outside atmosphere is disinfected under ultraviolet light after entering the disinfection chamber. Therefore, the ultraviolet sterilizer with a grid turntable proposed in this invention can disinfect items as well as circulate and disinfect indoor air, making it more versatile.

[0008] The ultraviolet sterilizer with a grid turntable proposed in this invention also has the following technical features:

[0009] In the above technical solution, the turntable is made of a transparent material that allows ultraviolet light to pass through.

[0010] In this technical solution, the turntable is made of transparent material so that when the ultraviolet component is placed at the bottom of the second housing, the ultraviolet rays emitted by the ultraviolet component can pass through the turntable and irradiate the bottom of the item to be disinfected, thereby disinfecting the bottom of the item.

[0011] The above technical solution also includes: a motor, located on the bottom wall of the second housing; the turntable is connected to the output shaft of the motor, and the motor drives the turntable to rotate in the disinfection chamber.

[0012] In this technical solution, a motor is installed on the bottom wall of the second housing. The turntable is connected to the output shaft of the motor. The motor drives the turntable to rotate in the disinfection chamber, so that the items to be disinfected placed on the turntable rotate with the turntable, which helps the ultraviolet rays to irradiate the items to be disinfected more fully, reduces the dead corners caused by the items blocking the ultraviolet rays, and improves the disinfection effect of the items.

[0013] In the above technical solution, there are multiple ultraviolet components, and some ultraviolet components are also disposed on the side wall or top wall of the inner wall of the second housing. The ultraviolet components specifically include: an ultraviolet lamp placement tube disposed on the inner wall of the second housing, an air channel for air flow and in which the ultraviolet lamp is placed is provided in the ultraviolet lamp placement tube, and the ultraviolet lamp can emit ultraviolet rays into the disinfection chamber through the tube wall of the ultraviolet lamp placement tube; wherein, one end of the air channel is connected to the outside atmosphere, and the other end is connected to the disinfection chamber through its corresponding first vent.

[0014] In this technical solution, the ultraviolet rays emitted by the ultraviolet lamps inside the ultraviolet lamp placement tube can penetrate the tube wall and enter the disinfection chamber to disinfect the items to be disinfected and the air inside the chamber. The ultraviolet lamp placement tube is equipped with an air channel for airflow, with one end connected to the outside and the other end connected to the disinfection chamber through a first vent. An air pump drives air to flow from one end of the air channel to the other, allowing outside air to enter the disinfection chamber through the air channel and the first vent. After passing through the through-hole on the turntable, it flows out through a second vent. As the outside air flows through the air channel, it is irradiated and disinfected by the ultraviolet rays emitted by the ultraviolet lamps inside the air channel. Upon entering the disinfection chamber, it undergoes secondary disinfection by the ultraviolet rays emitted through the tube wall of the ultraviolet lamp placement tube before being discharged from the disinfection chamber through the second vent. This ensures that outside air is disinfected under ultraviolet irradiation both through the air channel and the disinfection chamber, achieving circulating disinfection of indoor air. It should be noted that... After being disinfected through the air duct, the air enters the disinfection chamber, preventing active bacteria and viruses from the outside air from entering and causing secondary contamination of the items to be disinfected. It should also be noted that, due to the relatively large space within the disinfection chamber, the airflow velocity decreases, allowing the air to remain inside for a longer period. This facilitates more thorough disinfection by the ultraviolet light, improving the disinfection effect. Furthermore, if the items to be disinfected are damp dishes, clothing, etc., the airflow within the chamber accelerates moisture evaporation, resulting in rapid drying after disinfection. Optionally, when the air pump drives the air in the air duct, outside air can first enter the disinfection chamber through the second vent and then exit through the first vent and air duct. This prevents bacteria and viruses on the items from being blown up and released into the outside air before complete sterilization, thus avoiding indoor air pollution.

[0015] Understandably, another ultraviolet component can be added, with one end of the air channel of the other ultraviolet component connected to the second vent on the second housing and the other end connected to the outside atmosphere. This allows outside air to be disinfected by the disinfection lamp in the air channel when it enters the disinfection chamber or when the air in the disinfection chamber flows to the outside, thereby further improving the disinfection effect and avoiding cross-contamination between outside air and the items to be disinfected in the disinfection chamber.

[0016] In the above technical solution, the air channels of multiple ultraviolet lamp placement tubes are connected end to end in sequence, or the air channels of multiple ultraviolet lamp placement tubes are connected in parallel and then connected to the first ventilation port and the outside atmosphere respectively.

[0017] In this technical solution, multiple ultraviolet lamp placement tubes can be arranged in a tortuous manner on the inner wall of the second housing, making the air channel tortuous, so as to increase the total length of the air channel on the limited area of ​​the inner wall of the second housing, increase the disinfection time of the air in the air channel, and improve the sterilization and disinfection effect of the air. Alternatively, the air channels of multiple ultraviolet lamp placement tubes can be connected in parallel and connected to the disinfection chamber and the outside atmosphere respectively to increase the ventilation.

[0018] In the above technical solution, the ultraviolet lamp placement tube includes a connected quartz glass plate and a reflective base, the quartz glass plate and the reflective base defining an air passage; wherein, the quartz glass plate is located on the side facing the disinfection chamber; the side of the reflective base facing the quartz glass plate is provided with a first reflective layer that can reflect ultraviolet rays; or the reflective base is made of a material that can reflect ultraviolet rays; or the reflective base is made of an ultraviolet photochemical reaction material.

[0019] In this technical solution, the ultraviolet rays emitted by the ultraviolet lamp inside the ultraviolet lamp tube pass through the quartz glass plate and irradiate the disinfection chamber, disinfecting the items and air inside. A first reflective layer is provided on the reflective base to reflect ultraviolet rays, allowing the reflected ultraviolet rays to enter the disinfection chamber and air passage, increasing the utilization rate of ultraviolet rays and further improving the disinfection effect. Alternatively, the reflective base can be made of a material that reflects ultraviolet rays to reflect ultraviolet rays and allow the reflected ultraviolet rays to enter the disinfection chamber and air passage, increasing the utilization rate of ultraviolet rays and further improving the disinfection effect.

[0020] In the above technical solution, the ultraviolet component further includes: multiple air connecting pipes; a first ventilation hole and a second ventilation hole communicating with an air channel are respectively provided on the side walls at both ends of the length direction near the reflector base, and in any two adjacent reflector bases, the first ventilation hole of one reflector base is connected to the second ventilation hole of the other reflector base through an air connecting pipe. In this technical solution, the air connecting pipes connect two adjacent ultraviolet lamp placement tubes or connect the ultraviolet lamp placement tubes to the disinfection chamber, so as to facilitate the arrangement and setting of the ultraviolet lamp placement tubes on the inner wall of the second housing.

[0021] In the above technical solution, a second reflective layer for reflecting ultraviolet rays is provided on the inner wall of the first housing and / or the second housing.

[0022] In this technical solution, by providing a second reflective layer for reflecting ultraviolet rays on the inner wall of the first housing and / or the second housing, the ultraviolet rays emitted by the ultraviolet lamp are reflected back into the disinfection chamber by the second reflective layer. On the one hand, this increases the intensity of ultraviolet irradiation in the disinfection chamber, and on the other hand, it increases the irradiation angle of ultraviolet rays in the disinfection chamber, reduces the dead angle of ultraviolet irradiation, and improves the disinfection effect of the items to be disinfected.

[0023] In the above technical solution, the ultraviolet sterilizer with a grid turntable also includes: a bracket for placing items to be sterilized, the bracket being detachably mounted on the bottom wall of the second housing or on the turntable.

[0024] In this technical solution, a bracket is set on the bottom wall of the second housing to place multiple items to be disinfected on the bracket, thereby reducing the obstruction of ultraviolet light.

[0025] The above technical solution also includes: an air filtration device, which is located in the air channel or the second ventilation port. The air filtration device includes a dustproof filter layer and an odor-removing filter layer. The dustproof filter layer is provided with at least one dustproof filter screen, and the odor-removing filter layer is provided with activated carbon particles.

[0026] In this technical solution, dust and hair in the air are removed by an air filtration device, and activated carbon is added to the filter to remove odors.

[0027] Furthermore, it also includes a controller, which is located on the housing assembly. The controller is electrically connected to the ultraviolet lamp and controls the ultraviolet lamp to turn on or off.

[0028] The above technical solution also includes: an electric heating element, which is disposed in the disinfection chamber to heat the air in the disinfection chamber; the electric heating element is electrically connected to the controller, and the controller controls the electric heating element to be turned on or off.

[0029] In this technical solution, an electric heating element is installed inside the disinfection chamber to heat the air inside the chamber, thereby increasing the air temperature and accelerating the evaporation rate of moisture from the items to be disinfected.

[0030] The above technical solution also includes: a temperature sensor, which is installed inside the disinfection chamber to detect the air temperature inside the disinfection chamber; wherein the temperature sensor is electrically connected to the controller to feed back the air temperature to the controller, and the controller controls the electric heating element to turn on or off according to the air temperature.

[0031] In this technical solution, a temperature sensor is installed inside the disinfection chamber to detect the air temperature inside the chamber. The temperature sensor is electrically connected to the controller to feed the air temperature back to the controller. The controller controls the electric heating element to turn on or off based on the air temperature to prevent the air temperature inside the disinfection chamber from becoming too high and damaging the items to be disinfected. For example, when the items to be disinfected are plastic or other heat-sensitive materials, the controller will turn off the electric heating element when the air temperature is too high to prevent the air temperature inside the disinfection chamber from continuing to rise and causing high-temperature damage to the items to be disinfected.

[0032] In the above technical solution, when the air temperature is less than the first temperature threshold, the controller controls the electric heating element to turn on; when the air temperature is greater than the second temperature threshold, the controller controls the electric heating element to turn off; wherein, the second temperature threshold is greater than the first temperature threshold.

[0033] In this technical solution, when the air temperature is lower than the first temperature threshold, the controller controls the electric heating element to turn on, thereby increasing the air temperature in the disinfection chamber and accelerating moisture evaporation; when the air temperature is higher than the second temperature threshold, the controller controls the electric heating element to turn off, so as to avoid the air temperature in the disinfection chamber from continuously rising and causing high-temperature damage to the items to be disinfected. The second temperature threshold is higher than the first temperature threshold.

[0034] The above technical solution also includes: a humidity sensor, located inside the disinfection chamber, to detect the air humidity inside the disinfection chamber, and the humidity sensor is electrically connected to the controller; a display panel, located on the first housing and electrically connected to the controller; wherein, the display panel is provided with an operation interface, through which the electric heating element can be controlled to turn on or off; and the air temperature and air humidity are sent to the display panel through the controller, so that the air temperature and air humidity inside the disinfection chamber can be displayed in real time through the display panel.

[0035] In this technical solution, a humidity sensor is installed inside the disinfection chamber to detect the air humidity inside the disinfection chamber. A display panel electrically connected to the controller is installed on the first housing. The humidity sensor is electrically connected to the controller, so that the air humidity is sent to the display panel through the controller, so that the air humidity inside the disinfection chamber can be displayed in real time through the display panel, which makes it convenient for users to understand the dryness of the items to be disinfected in real time. The display panel is equipped with an operation interface, through which the electric heating element can be turned on or off.

[0036] The above technical solution also includes: a safety lock assembly, which includes a trigger and a sensor electrically connected to the controller. One of the trigger and the sensor is located on the first housing, and the other is located on the second housing. When the disinfection chamber is closed, the trigger triggers the sensor, and the sensor sends an electrical signal to the controller. The controller then controls the ultraviolet lamp to turn on according to the electrical signal. When the disinfection chamber is open, the trigger does not trigger the sensor, and the controller controls the ultraviolet lamp to turn off.

[0037] In this technical solution, the safety lock assembly includes a trigger and a sensor, one of which is located on the first housing and the other on the second housing. When the disinfection chamber is closed, the trigger activates the sensor, which sends an electrical signal to the controller. The controller then controls the UV lamp to turn on based on the electrical signal. When the disinfection chamber is open, the trigger does not activate the sensor, and the controller controls the UV lamp to turn off. This ensures that when a user opens the UV sterilizer with the grid disc, the UV lamp automatically turns off, preventing UV radiation from reaching the human body and causing harm.

[0038] The above technical solution also includes: a communication module, which is electrically connected to the controller; with the support of the communication module, the controller interacts with the smart device through at least one communication protocol to upgrade the controller's control logic, or controls the operation of the ultraviolet sterilizer with a grid turntable through the smart device.

[0039] The beneficial effects of the technical solution provided by the embodiments of the present invention are: it can disinfect the bottom of bowls, plates, tableware and other items, reducing dead corners of the items to be disinfected, and can also make the moisture on the bottom and other parts of bowls, plates, tableware and other items evaporate quickly, so as to facilitate the rapid drying of various parts of bowls, plates, tableware and other items; it can disinfect items and also circulate and disinfect indoor air, making it more versatile.

Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention and their beneficial effects will be further described in detail below with reference to the accompanying drawings.

[0055] like Figure 1 The present invention provides an ultraviolet sterilizer with a grid turntable, which is defined as follows:

[0056] The ultraviolet sterilizer with a grid turntable includes: a housing assembly 1, an ultraviolet component 2, a turntable 4, and an air pump 3. The housing assembly 1 includes a first housing 12 and a second housing 14 hinged together, defining a sterilization chamber 18. The sterilization chamber 18 is opened or closed by rotating the first housing 12 relative to the second housing 14, facilitating the placement of items to be sterilized into or removal of sterilized items from the sterilization chamber 18. The bottom of the second housing 14 has a first vent 10 connecting the sterilization chamber 18 to the outside atmosphere. 8. Air inside the disinfection chamber 18 can flow out through the first vent 108, or outside air can flow into the disinfection chamber 18 through the first vent 108; ultraviolet rays emitted by the ultraviolet component 2 can penetrate into the disinfection chamber 18 to disinfect the items to be disinfected placed inside the chamber and the air inside. Specifically, at least one ultraviolet component 2 is disposed on the bottom wall of the second housing 14, so that the ultraviolet rays emitted by the ultraviolet component 2 irradiate upwards from the bottom of the disinfection chamber 18. Furthermore, a turntable 4 is also disposed above the ultraviolet component 2, and the turntable 4 is used to place the items to be disinfected, such as... Figure 2 As shown, specifically, the turntable 4 is provided with multiple through holes 42, making the turntable 4 grid-like, allowing air and ultraviolet light to pass through the through holes 42 on the turntable 4. On the one hand, this facilitates the disinfection of the bottom of the items to be disinfected placed on the turntable 4; on the other hand, when the air passes through the through holes 42 on the turntable 4, it can carry away the moisture at the bottom of the items to be disinfected, so as to facilitate the evaporation of the moisture at the bottom of the items to be disinfected. The top of the first housing 12 or the second housing 14 is provided with a second vent 110 that connects the disinfection chamber 18 with the outside atmosphere. The first vent 108 and / or the second vent 110 are equipped with an air pump 3, thereby driving the outside air to enter the bottom of the disinfection chamber 18 from the first vent 108, pass through the through holes 42 on the turntable 4, pass through the items to be disinfected placed on the turntable 4, and then exit from the second vent 110 to accelerate the evaporation of the moisture on the items to be disinfected. Specifically, the direction of airflow is the direction indicated by the arrow in 1.

[0057] Understandably, if the items to be disinfected are damp items such as bowls, plates, and tableware, the technical solution proposed in this invention can not only disinfect the bottom of the items such as bowls, plates, and tableware, reducing dead corners of the items to be disinfected, but also allow the moisture on the bottom and other parts of the items such as bowls, plates, and tableware to evaporate quickly, so as to facilitate the rapid drying of all parts of the items such as bowls, plates, and tableware.

[0058] It should be emphasized that the air in the outside atmosphere is disinfected under ultraviolet light after entering the disinfection chamber 18. Therefore, the ultraviolet sterilizer with a grid turntable proposed in this invention can disinfect items as well as circulate and disinfect indoor air, making it more versatile.

[0059] like Figure 3 and Figure 4 As shown, the ultraviolet component 2 is not only located on the bottom wall of the second housing 14, but also on the side wall of the second housing 14, in order to increase the irradiation intensity of ultraviolet rays in the disinfection chamber 18, and to form multiple ultraviolet irradiation points, increase the incident angle of ultraviolet rays, and reduce the ultraviolet irradiation dead angles, so as to disinfect the items to be disinfected more comprehensively.

[0060] Furthermore, the turntable 4 is made of a transparent material that allows ultraviolet light to pass through, so that the light emitted by the ultraviolet component 2 located on the bottom wall of the second housing 14 can pass through the turntable 4 and directly irradiate the bottom of the item to be disinfected, thus disinfecting the bottom of the item. The material of the turntable 4 is a plastic material with high ultraviolet transmittance, or for example, a dark or black glass material that is opaque to visible light but highly transparent to ultraviolet light. Understandably, it can also be any other ultraviolet light-transmitting material that allows ultraviolet light to pass through.

[0061] like Figure 2 and Figure 4 As shown, the first housing 12 and the second housing 14 can have different structures such as diagonal opening, front opening, and top and bottom flip-tops.

[0062] Among them, turntable 4 is made of porous metal or plastic mesh.

[0063] like Figure 1 and Figure 3 As shown, the ultraviolet sterilizer with a grid turntable also includes a motor 44, which is located on the bottom wall of the second housing 14. The turntable 4 is connected to the output shaft of the motor 44. The motor 44 drives the turntable 4 to rotate in the sterilization chamber 18, so that the items to be sterilized placed on the turntable 4 rotate with the turntable 4, so that the ultraviolet rays can irradiate the items to be sterilized more fully, reduce the dead corners caused by the items blocking the ultraviolet rays, and improve the sterilization effect of the items.

[0064] like Figure 1 As shown, in one embodiment of the present invention, the following is further defined:

[0065] like Figure 3 and Figure 5As shown, there are multiple ultraviolet (UV) components 2, some of which are located on the side or top wall of the inner wall of the second housing 14. Each UV component 2 specifically includes a UV lamp placement tube 22 and a UV lamp 24. Specifically, the UV lamp placement tube 22 has an air channel 228 for airflow. The UV lamp 24 is placed within the air channel 228. The ultraviolet rays emitted by the UV lamp 24 can penetrate the tube wall of the UV lamp placement tube 22 and enter the disinfection chamber 18 to disinfect the items to be disinfected and the air within the disinfection chamber. One end of the air channel 228 is connected to the outside, and the other end is connected to the disinfection chamber 18 through a first vent 108. The air pump 3 drives air to flow from one end of the air channel 228 to the other, allowing outside air to enter through the air channel 228 and the first vent 108. The air enters the disinfection chamber 18, passes through the through-hole 42 on the turntable 4, and then flows out through the second vent 110. This allows outside air to be disinfected by ultraviolet light emitted from the ultraviolet lamp 24 within the air channel 228 as it flows through it. Furthermore, after entering the disinfection chamber 18, it undergoes secondary disinfection by ultraviolet light emitted through the wall of the ultraviolet lamp placement tube 22. The air then exits the disinfection chamber 18 through the second vent 110. This ensures that outside air is disinfected under ultraviolet light irradiation both through the air channel 228 and the disinfection chamber 18, achieving circulating disinfection of indoor air. It should be noted that the air enters the disinfection chamber 18 after being disinfected through the air channel 228 to prevent active bacteria and viruses from entering the disinfection chamber 18 and causing secondary contamination of the items to be disinfected. The direction of airflow is... Figure 3 and Figure 5 The direction indicated by the middle arrow; it should also be noted that after the air flows into the disinfection chamber 18, due to the relatively large space inside the disinfection chamber 18, the air flow rate decreases after flowing into the disinfection chamber 18, and the air can stay in the disinfection chamber 18 for a longer time, so as to facilitate more thorough disinfection of the air by ultraviolet rays and improve the disinfection effect. It should also be noted that if the items to be disinfected in the disinfection chamber 18 are damp dishes, clothes, etc., the flow of air in the disinfection chamber 18 can accelerate the evaporation of moisture and make the disinfected items dry quickly; optionally, when the air pump 3 drives the air in the air channel 228, it can also make the outside air enter the disinfection chamber 18 first through the second vent 110, and then flow out through the first vent 108 and the air channel 228, so as to avoid blowing bacteria and viruses on the items to be disinfected into the outside air when the air flows through the items to be disinfected in the disinfection chamber 18 before they are completely sterilized, thus causing indoor air pollution.

[0066] like Figure 3 As shown, in one specific embodiment, the air pump 3 is mounted on the air connecting pipe 26.

[0067] Understandably, another ultraviolet component 2 can also be added, with one end of the air channel 228 of the other ultraviolet component 2 connected to the second vent 110 on the second housing 14 and the other end connected to the outside atmosphere. This allows the outside air to be irradiated and disinfected by the disinfection lamp in the air channel 228 when it enters the disinfection chamber 18 or when the air in the disinfection chamber 18 flows to the outside, thereby further improving the disinfection effect and avoiding cross-contamination between the outside air and the items to be disinfected in the disinfection chamber 18.

[0068] Among them, the ultraviolet lamp 24 can be, but is not limited to, mercury lamp tubes, ultraviolet LEDs, deep ultraviolet LEDs, etc.

[0069] like Figure 3 Figure 5 As shown, further, the air channels 228 of the multiple ultraviolet lamp placement tubes 22 are connected end to end in sequence. The multiple ultraviolet lamp placement tubes 22 can be arranged in a tortuous manner on the inner wall of the second housing 14, so that the air channels 228 are tortuous. This increases the total length of the air channels 228 on the inner wall of the second housing 14 with limited area, increases the disinfection time of the air in the air channels 228, and improves the sterilization and disinfection effect of the air. Alternatively, the air channels 228 of the multiple ultraviolet lamp placement tubes 22 can be connected in parallel to the disinfection chamber 18 and the outside atmosphere respectively to increase the ventilation volume.

[0070] like Figure 6 , Figure 7 and Figure 8 As shown, the ultraviolet lamp placement tube 22 further includes a connected quartz glass plate 222 and a reflective base 224. The quartz glass plate 222 and the reflective base 224 define an air channel 228. The ultraviolet rays emitted by the ultraviolet lamp 24 in the ultraviolet lamp placement tube 22 pass through the quartz glass plate 222 and irradiate the disinfection chamber 18, disinfecting the items and air in the disinfection chamber 18. The reflective base 224 is provided with a first reflective layer 226 that can reflect ultraviolet rays, so that the first reflective layer 226 can reflect ultraviolet rays and shoot the reflected ultraviolet rays into the disinfection chamber 18 and the air channel 228, increasing the utilization rate of ultraviolet rays and further improving the disinfection effect; or the reflective base 224 is made of a material that can reflect ultraviolet rays to reflect ultraviolet rays and shoot the reflected ultraviolet rays into the disinfection chamber 18 and the air channel 228, increasing the utilization rate of ultraviolet rays and further improving the disinfection effect.

[0071] The material of the first reflective layer 226 may be, but is not limited to, Teflon, stainless steel, aluminum, aluminized plastic, silicon dioxide, calcium sulfate, etc. Materials that reflect ultraviolet light, such as reflective materials, can also be photocatalytic coatings.

[0072] like Figure 3As shown, the ultraviolet component 2 further includes: multiple air connecting pipes 26; first ventilation holes 2242 and second ventilation holes 2244 communicating with air channels 228 are respectively provided on the side walls near both ends of the reflector base 224 in the length direction; in any two adjacent reflector bases 224, the first ventilation hole 2242 of one reflector base 224 and the second ventilation hole 2244 of the other reflector base 224 are connected by an air connecting pipe 26. In this technical solution, the air connecting pipes 26 connect two adjacent ultraviolet lamp placement tubes 22 or connect the ultraviolet lamp placement tubes 22 with the disinfection chamber 18, so as to facilitate the arrangement and setting of the ultraviolet lamp placement tubes 22 on the inner wall of the second housing 14.

[0073] The material of the reflector base 224 may be, but is not limited to, stainless steel, aluminum, or aluminized plastic.

[0074] like Figure 4 As shown, in one embodiment of the present invention, the following is further defined:

[0075] A second reflective layer 16 for reflecting ultraviolet rays is provided on the inner wall of the first housing 12, so that the ultraviolet rays emitted by the ultraviolet lamp 24 are reflected back into the disinfection chamber 18 under the reflection of the second reflective layer 16. On the one hand, it increases the intensity of ultraviolet irradiation in the disinfection chamber 18, and on the other hand, it increases the irradiation angle of ultraviolet rays in the disinfection chamber 18, reduces the dead angle of ultraviolet irradiation, and improves the disinfection effect of the items to be disinfected.

[0076] Alternatively, a second reflective layer 16 for reflecting ultraviolet rays can be provided on the inner wall of the second housing 14, so that the ultraviolet rays emitted by the ultraviolet lamp 24 are reflected back into the disinfection chamber 18 by the second reflective layer 16. The ultraviolet light is reflected multiple times in the disinfection chamber 18, which improves the utilization rate of ultraviolet light and increases the coverage of ultraviolet light. On the one hand, it increases the intensity of ultraviolet irradiation in the disinfection chamber 18, and on the other hand, it increases the irradiation angle of ultraviolet rays in the disinfection chamber 18, reduces the dead angle of ultraviolet irradiation, and improves the disinfection effect of the items to be disinfected.

[0077] Alternatively, a second reflective layer 16 for reflecting ultraviolet rays can be provided on the inner walls of the first housing 12 and the second housing 14, so that the ultraviolet rays emitted by the ultraviolet lamp 24 can be reflected back into the disinfection chamber 18 under the reflection of the second reflective layer 16. On the one hand, this increases the intensity of ultraviolet irradiation in the disinfection chamber 18, and on the other hand, it increases the irradiation angle of ultraviolet rays in the disinfection chamber 18, reduces the dead angle of ultraviolet irradiation, and improves the disinfection effect of the items to be disinfected.

[0078] The material of the second reflective layer 16 may be, but is not limited to, Teflon, stainless steel, aluminum, aluminized plastic, silicon dioxide, calcium sulfate, etc. Materials that reflect ultraviolet light, such as reflective materials, can also be photocatalytic coatings.

[0079] like Figure 2 As shown, in a preferred embodiment of the present invention, the following is further defined:

[0080] The ultraviolet sterilizer with a grid turntable also includes a support 5 for placing items to be sterilized. The support 5 is detachably mounted on the bottom wall of the second housing 14 so that multiple items to be sterilized can be placed on the support 5 to reduce the obstruction of ultraviolet light. The support 5 can be made of materials such as quartz glass, metal or plastic.

[0081] like Figure 5 and Figure 9 As shown, the ultraviolet sterilizer with a grid turntable also includes an air filter device 6, which is located in the air channel 228 or the second vent 110. The air filter device 6 includes a dustproof filter layer 62 and an odor-removing filter layer 64. The dustproof filter layer 62 is provided with at least one dustproof filter screen, and the odor-removing filter layer 64 is provided with activated carbon particles.

[0082] Alternatively, air filter devices 6 can be installed in both air duct 228 and second vent 110 to remove dust and hair from the air, while activated carbon is added to the filter to remove odors.

[0083] Furthermore, the dust filter layer 62 uses a HEPA filter element, which purifies the air while also sterilizing it.

[0084] like Figure 12 As shown, in one embodiment of the present invention, the following is further defined:

[0085] The ultraviolet sterilizer with a grid turntable also includes a controller 10, which is mounted on the housing assembly 11. The controller 10 is electrically connected to the ultraviolet lamp 24 and controls the ultraviolet lamp 24 to turn on or off. An electric heating element 30 is installed in the sterilization chamber 18 to heat the air in the sterilization chamber, increase the air temperature in the sterilization chamber 18, and increase the moisture evaporation rate of the items to be sterilized. The electric heating element 30 is electrically connected to the controller 10, and the controller 10 controls the electric heating element 30 to turn on or off.

[0086] like Figure 3 As shown, in a specific embodiment, the electric heating element 30 is disposed between the first vent 108 and the turntable 4. After the air pump 3 drives the air to enter the disinfection chamber 18 from the first vent 108, it is first heated by the electric heating element 30, and then hot air is blown onto the turntable 4. The hot air passes through the through hole 42 on the turntable 4 and flows upward from the bottom of the item to be disinfected, thereby accelerating the evaporation of moisture on the item to be disinfected.

[0087] like Figure 2As shown, a temperature sensor 402 is further installed inside the disinfection chamber 18 to detect the air temperature inside the disinfection chamber 18. The temperature sensor 402 is electrically connected to the controller 10 to feed back the air temperature to the controller 10. The controller 10 controls the electric heating element 30 to turn on or off according to the air temperature to avoid the air temperature inside the disinfection chamber 18 becoming too high and damaging the items to be disinfected. For example, when the items to be disinfected are plastic or other heat-sensitive items, the controller 10 controls the electric heating element 30 to turn off when the air temperature is too high to prevent the air temperature inside the disinfection chamber 18 from continuing to rise and causing high-temperature damage to the items to be disinfected.

[0088] Specifically, when the air temperature is lower than the first temperature threshold, the controller 10 controls the electric heating element 30 to turn on, thereby increasing the air temperature in the disinfection chamber 18 and accelerating moisture evaporation; when the air temperature is higher than the second temperature threshold, the controller 10 controls the electric heating element 30 to turn off, so as to avoid the air temperature in the disinfection chamber 18 from continuously rising and causing high temperature damage to the items to be disinfected, wherein the second temperature threshold is higher than the first temperature threshold.

[0089] The first and second temperature thresholds can be set to different values ​​depending on the items to be disinfected. For example, for heat-resistant items such as glass, porcelain, and metal, the first and second temperature thresholds can be set relatively high, such as setting the first temperature threshold to 40℃ and the second temperature threshold to 100℃, or setting the first temperature threshold to 40℃ and the second temperature threshold to 80℃, etc. For heat-sensitive items such as silk and plastic products, the first and second temperature thresholds can be set relatively low, such as setting the first temperature threshold to 30℃ and the second temperature threshold to 50℃, or setting the first temperature threshold to 30℃ and the second temperature threshold to 60℃, etc.

[0090] like Figure 2 and Figure 11 As shown, a humidity sensor 40 is further installed inside the disinfection chamber 18 to detect the air humidity inside the disinfection chamber 18. The humidity sensor 40 is electrically connected to the controller 10. A display panel is installed on the first housing 12 and is electrically connected to the controller 10. The display panel has an operation interface, through which the electric heating element 30 can be turned on or off. Users can actively select heating mode or non-heating mode, thereby adjusting the working mode of the ultraviolet sterilizer with grid turntable according to the actual needs of the customer. The air temperature and air humidity are sent to the display panel through the controller 10 so that the air temperature and air humidity inside the disinfection chamber 18 can be displayed in real time, allowing users to better understand the air temperature and air humidity inside the disinfection chamber 18 and to facilitate users to understand the dryness of the items to be disinfected in real time.

[0091] like Figure 10 As shown, the sterilizer is further equipped with a safety lock. Specifically, the safety lock assembly 8 includes a trigger 82 and a sensor 84, one of which is located on the first housing 12 and the other on the second housing 14. When the sterilization chamber 18 is closed, the trigger 82 triggers the sensor 84, which sends an electrical signal to the controller 10. The controller 10 then controls the UV lamp 24 to turn on based on the electrical signal. When the sterilization chamber 18 is open, the trigger 82 does not trigger the sensor 84, and the controller 10 controls the UV lamp 24 to turn off. This ensures that when the user opens the UV sterilizer with the grid disc, the UV lamp 24 automatically turns off, preventing UV radiation from reaching the human body and causing harm. Specifically, the trigger 82 is a magnet, and the sensor 84 is a Hall switch. The Hall switch is located on the second housing 14, and a fixed magnet is located at a corresponding position on the first housing 12. When the sterilization chamber 18 is closed, the Hall switch can sense the magnetic field of the magnet and determine that the front cover is closed, at which point the UV lamp 24 can be turned on. Otherwise, the UV lamps should not be turned on, or any UV lamps that are already on should be turned off immediately to prevent ultraviolet rays from irradiating the human body and causing harm to the user.

[0092] like Figure 10 As shown, the ultraviolet sterilizer with a grid turntable also includes: a communication module 60, which is electrically connected to the controller 10;

[0093] With the support of the communication module 60, the controller 10 interacts with smart devices via at least one communication protocol to upgrade its control logic or control the operation of the UV sterilizer with a grid turntable via the smart device. Specifically, the communication protocol can be, but is not limited to, Wi-Fi, Bluetooth, 4G, and 5G, and the smart device can be a mobile phone, tablet, cloud server, or other terminal. By setting up the communication module 60, the IoT function of the UV sterilizer with a grid turntable can be realized, such as analyzing user characteristics and usage habits, and combining AI algorithms to upgrade firmware and sterilization functions. For example, based on published real-time monitoring data, if the air quality in a user's area is poor, the UV sterilizer with a grid turntable can be upgraded and its control logic can be changed through algorithms and big data analysis. For example, it can generate a selection mode that suggests the user's sterilization time and frequency, and make corresponding intelligent adjustments, such as adjusting the sterilization time and the output power of the UV lamp. Users can also use smart devices such as mobile phones and computers to remotely control the sterilizer to sterilize indoor air and maintain high indoor air quality.

[0094] The beneficial effects of this invention are as follows: it can disinfect the bottoms of bowls, plates, and other tableware, reducing blind spots for disinfection; it can also quickly evaporate moisture from the bottoms and other parts of bowls, plates, and other tableware, facilitating rapid drying of all parts; it can disinfect both items and circulate and disinfect indoor air, while avoiding cross-contamination between outside air and the items to be disinfected inside the disinfection chamber, thus broadening its applications.
