Detailed Implementation

[0034] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] Please refer to the specific details. Figure 5As shown, this utility model discloses a dual-internal-flow-channel disinfection device, which can disinfect tableware (such as bowls, chopsticks, spoons, cups, etc.) and some medical instruments (such as tweezers, scissors) stored inside the disinfection device to disinfect bacteria, viruses and microorganisms. The disinfection device mainly adopts high-temperature drying disinfection, and can also use ultraviolet disinfection and ozone disinfection as auxiliary methods. The dual-internal-flow-channel disinfection device includes a main body 1, wherein the main body 1 has a first inner chamber 121 and a second inner chamber 122. Specifically, the main body 1 has an inner liner with the first inner chamber 121 and the second inner chamber 122, and an outer shell bottom plate 143, an outer shell top plate 141, an outer shell back plate and an outer shell side plate 142 assembled on the outside of the inner liner. The outer shell bottom plate 143 is used to abut against a base body (such as a tabletop, ground, tabletop, etc.), and the outer shell top plate 141 is arranged opposite to the outer shell bottom plate 143. The outer shell top plate 141, the outer shell bottom plate 143 and the outer shell back plate are all fixedly connected to the outer shell side plate 142. The fixed connection here should be understood as a snap-fit ​​connection or a bolt connection or other outer shell assembly connection method. The direction from the bottom plate 143 of the outer casing to the top plate 141 of the outer casing is defined as the height direction of the main body 1 of the equipment. In the height direction of the main body 1 of the equipment, the first inner chamber 121 is located at the bottom of the second inner chamber 122, and the first inner chamber 121 and the second inner chamber 122 are set independently.

[0038] In this embodiment, please refer to the details. Figure 5 and Figure 6 As shown, the main body 1 of the device also includes a heating device 11 and an ultraviolet lamp. The heating device 11 is preferably a heating lamp, but can also be a heating plate. The ultraviolet lamp is installed in the second inner chamber 122. The heating device 11 is preferably located inside the first inner chamber 121 and is fixedly mounted on the side of the inner liner near the back plate of the outer shell, so that tableware or medical instruments can be placed into the first inner chamber 121. In other embodiments, a heating chamber communicating with the first inner chamber 121 can be formed between the inner liner and the bottom plate 143 of the outer shell. The heating device 11 is installed and fixed in the heating chamber, and can supply heat to the first inner chamber 121, thereby achieving the purpose of high-temperature sterilization of tableware or medical instruments in the first inner chamber 121, while ultraviolet sterilization is performed on tableware or medical instruments in the second inner chamber 122 that cannot be sterilized at high temperature.

[0039] Furthermore, please refer to the specific details. Figures 1 to 4 As shown, the dual-internal-channel disinfection device also includes a heat transfer component 2, which has a drive fan 21 and a fluid reversing plate 22. The heat transfer component 2 has a first drainage channel 231 and a second drainage channel 232 inside. The drive fan 21 and the fluid reversing plate 22 are both located in the area where the first drainage channel 231 and the second drainage channel 232 intersect. Further, as... Figures 8 to 12As shown, the heat transfer component 2 is installed on the main body 1 of the device.

[0040] Please refer to the specific settings for details. Figure 4 , Figure 9 and Figure 10 As shown, the dual-internal-flow-channel sterilization device is in its first state. Activating the drive fan 21 creates a negative pressure inside the first inner chamber 121, causing hot air to flow into the heat transfer assembly 2. The hot air entering the heat transfer assembly 2 flows from one side of the first inner chamber 121 along the center line of the first drainage channel 231 towards the other side, and finally returns to the first inner chamber 121. This creates airflow within the first inner chamber 121, which not only facilitates faster heat transfer from the heating device 11 to the entire first inner chamber 121, improving heating efficiency and shortening drying time, but also ensures that a large amount of heat is fully diffused throughout the first inner chamber 121, preventing uneven temperature distribution and ensuring that all tableware or medical instruments in the first inner chamber 121 receive thorough and complete high-temperature sterilization. Understandably, the first state is the working state of high temperature sterilization, and due to the obstruction of the fluid reversing plate 22, the hot air will not flow into the second drainage channel 232.

[0041] Please refer to the specific details. Figure 3 , Figure 11 and Figure 12 As shown, when high-temperature sterilization is completed, the dual-internal-flow-channel disinfection device is in the second state. At this time, the heating device 11 stops heating or enters a low-power heat preservation mode, while the drive fan 21 remains in operation, keeping the interior of the first inner chamber 121 under negative pressure and generating hot air flow into the heat transfer component 2. The hot air entering the heat transfer component 2 flows from the first inner chamber 121 along the center line of the second drainage channel 232 towards the interior of the second inner chamber 122, allowing the heat in the first inner chamber 121 to quickly dissipate from the second inner chamber 121. The water discharged from the first inner chamber 121 is guided into the second inner chamber 122 by the second drainage channel 232, thereby achieving rapid cooling of the first inner chamber 121 and shortening the cooling time. This can effectively avoid the risk of burns when users take tableware or medical instruments out of the first inner chamber 121, and also prevent the water vapor in the first inner chamber 121 from not being completely and timely discharged, which would lead to condensation in the first inner chamber 121. This also effectively reduces the risk of rust and bacterial growth in the inner liner due to condensation, and better ensures the hygiene of tableware and medical instruments.

[0042] Furthermore, the residual heat of the first inner chamber 121 can be fully utilized to improve the sterilization effect of the second inner chamber 122. Specifically, the residual heat of the first inner chamber 121 is guided into the second inner chamber 122, allowing the heat to quickly dry and sterilize the parts of the tableware or medical instruments in the second inner chamber 122 that were not covered by ultraviolet light. This effectively improves the sterilization effect of the second inner chamber 122 and enables rapid drying of the tableware and medical instruments within it. Simultaneously, it significantly reduces residual heat loss, increasing the energy utilization rate of this dual-channel disinfection equipment. The residual heat here should be explained as follows: the temperature of the hot air entering the second inner chamber 122 is lower than the temperature of the hot air in the first inner chamber 121, for example, it can be 2-3 degrees Celsius lower, or 5-10 degrees Celsius lower, to meet the sterilization needs of some materials that cannot be exposed to high-temperature environments for a long time. However, it is not limited to this temperature value. The residual heat temperature entering the second inner chamber 122 can be adjusted according to the program settings. This application does not limit the temperature value. It is understood that this second state is a stopped state or a low-temperature state, and due to the obstruction of the fluid diversion plate 22, the hot air will not flow into the first drainage channel 231 and will flow back into the first inner chamber 121.

[0043] It should be added that, for details please refer to... Figure 5 As shown, the main body 1 of the device is also provided with a first vent 131 and a second vent 132. The first inner chamber 121 is connected to the outside of the main body 1 of the device through the first vent 131. For example, the first vent 131 is a lower cavity vent hole provided on the inner wall of the first inner chamber 121. When the inside of the first inner chamber 121 is in a negative pressure state, the outside air will enter the first inner chamber 121 through the first vent 131, ensuring the pressure balance of the first inner chamber 121. When the dual inner flow channel disinfection device is in the second state, it will also accelerate the cooling efficiency of the first inner chamber 121. The second inner chamber 122 is connected to the outside of the main body 1 through the second vent 132. For example, the second vent 132 is an upper vent hole provided on the inner wall of the second inner chamber 122. When hot air enters the interior of the second inner chamber 122, the air compressed in the second inner chamber 122 and the hot air flowing through the tableware and medical instruments are discharged through the second vent 132, ensuring the pressure balance of the second inner chamber 122 while improving the drying effect. Of course, the position and number of the lower vent holes can be set and adjusted according to the structural design and design requirements, and the position and number of the upper vent holes can also be set and adjusted according to the structural design and design requirements.

[0044] As a preferred embodiment, please refer to the following for details. Figure 3 and Figure 4As shown, the heat transfer component 2 has an internal ventilation cavity 237 and a first port 233 that connects to the ventilation cavity 237. The main body 1 of the device has a first air guide port 123 corresponding to the first port 233. The first inner chamber 121 is connected to the first port 233 through the first air guide port 123. The first drainage channel 231 and the second drainage channel 232 are both connected to the ventilation cavity 237. The drive fan 21 is installed and fixed in the ventilation cavity 237.

[0045] For example, please see Figures 1 to 12 Assuming that the first opening 233 is an air inlet, under the action of the driving fan 21, the hot air in the first inner chamber 121 will enter the ventilation inner chamber from the first opening 233, and then flow through the driving fan 21 and enter the first drainage channel 231 or the second drainage channel 232. Furthermore, the heat transfer component 2 is also provided with a second port 234 and a third port 235. The second port 234 is connected to the first drainage channel 231, and the third port 235 is connected to the second drainage channel 232. Both the second port 234 and the third port 235 are air outlets. The main body of the device is provided with a second air guide port 124 corresponding to the second port 234 and a third air guide port 125 corresponding to the third port 235. The first inner chamber 121 is connected to the second port 234 through the second air guide port 124. Hot air flows from the first drainage channel 231 through the second port 234 and the second air guide port 124 in sequence and then flows back into the first inner chamber 121. Alternatively, hot air flows from the second drainage channel 232 through the third port 235 and the third air guide port 125 in sequence and then flows back into the second inner chamber 122. Of course, if the first opening 233 is the air outlet, then the second opening 234 and the third opening 235 are both air inlets. Therefore, the direction of hot air flow is opposite to that described above, which will not be repeated here.

[0046] Preferably, please refer to the following for details. Figures 1 to 12 As shown, the centerline of the first drainage channel 231 is perpendicular to the centerline of the second drainage channel 232. This minimizes the resistance of the hot air, preventing vortices from forming in the area where the hot air intersects with the first and second drainage channels 232, thus improving the flow efficiency of the hot air. Simultaneously, it allows for a simpler and more compact structure for the heat transfer assembly 2. In some embodiments, depending on design requirements or structural design, the centerline of the first drainage channel 231 may also be inclined to the centerline of the second drainage channel 232.

[0047] Furthermore, please refer to the specific details. Figure 3 and Figure 4As shown, the flow channel sidewall of the first flow channel 231 intersects with the flow channel sidewall of the second flow channel 232 to form a reversing angle portion 236. A venting cavity 238 is provided between the venting cavity 237 and the first flow channel 231. The second flow channel 232 and the venting cavity 238 are respectively located on two opposite sides of the first flow channel 231. Along the extension direction of the second flow channel 232, the reversing angle portion 236 is within the projection range of the venting cavity 238. The fluid reversing plate 22 is hinged to the reversing angle portion 236. With this configuration, after the hot air enters the area where the first flow channel 231 and the second flow channel 232 intersect, it will be constrained by the fluid reversing plate 22 and smoothly flow into the first flow channel 231 or the second flow channel 232 under the guidance of the fluid reversing plate 22, further reducing the resistance of the hot air and thus further improving the flow efficiency and stability of the hot air.

[0048] It should be noted that the heat transfer assembly 2 also includes a reversing drive, which is connected to the fluid reversing plate 22 to deflect it. The reversing drive is mounted and fixed on the main body 1 of the equipment. For example, the reversing drive can be a motor, in which case the fluid reversing plate 22 can be connected to the reversing drive via a belt drive mechanism. Alternatively, the reversing drive can be a servo motor, in which case the fluid reversing plate 22 can be connected to the reversing drive via a gear drive mechanism. Or, the reversing drive can be a cylinder, in which case the fluid reversing plate 22 can be connected to the reversing drive via a rack and pinion mechanism.

[0049] As a preferred embodiment, please refer to the following for details. Figures 8 to 12 As shown, the extension direction of the second drainage channel 232 is consistent with the height direction of the main body 1 of the equipment, so as to facilitate the processing (such as the processing of the first air inlet 123, the second air inlet 124, and the third air inlet 125) and positioning and installation of the dual internal flow channel disinfection equipment, thereby improving processing efficiency and assembly efficiency.

[0050] Furthermore, please refer to the specific details. Figures 8 to 12 As shown, the heat transfer component 2 is assembled on the outside of the first inner chamber 121 of the main body of the device 1, which will further improve the assembly efficiency and ease of assembly of the dual internal flow channel disinfection device.

[0051] As a preferred embodiment, please refer to the following for details. Figures 8 to 12As shown, the heat transfer component 2 and the heating device 11 are both installed on the same cavity wall of the main body 1. When hot air enters the ventilation cavity 237, it flows around the heating device 11, initially absorbing the heat released by the heating device 11. When the hot air enters the first inner chamber 121 from the second air inlet 124, it absorbs the heat released by the heating device 11 a second time, ensuring that the area far from the heating device 11 still has a lot of heat, further improving the heat uniformity inside the first inner chamber 121. In addition, the second drainage channel 232 extends along the height direction of the main body 1, reducing the extension distance of the second drainage channel 232, which effectively reduces heat loss during the flow process of the second drainage channel 232, thereby ensuring that more residual heat enters the second inner chamber 122, further improving energy utilization.

[0052] As a preferred embodiment, please refer to the following for details. Figure 1 and Figure 2 As shown, the heat transfer assembly 2 also includes a ventilation base 24 and a ventilation cover 25. The ventilation base 24 and the ventilation cover 25 are engaged. For example, one of the ventilation base 24 and the ventilation cover 25 is provided with a snap-fit ​​structure, and the other is provided with a snap-fit ​​structure that engages with the snap-fit ​​structure. The ventilation base 24 and the ventilation cover 25 cooperate to form a first drainage channel 231, a second drainage channel 232, and a ventilation cavity 237. This configuration improves the assembly efficiency and ease of assembly of the heat transfer assembly 2.

[0053] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
