[0002] Kitchen utensils (such as chopping boards, knives, etc.) are often in direct contact with food, stains, etc., and are prone to bacterial growth, which affects people's physical health. For this reason, disinfection devices for kitchen utensils have emerged on the market, such as chopping board disinfection machines, which can disinfect chopping boards, knives, etc. to prevent bacterial growth. However, after long-term use of the chopping board disinfection machine, bacteria are also prone to grow inside it, causing mildew and bad smell, which affects the user's safety.

[0003] For this reason, a split-type and detachable chopping board disinfection machine has emerged, and users can disassemble it as a whole for cleaning. However, this disassembly and cleaning method causes great loss to the service life of the whole machine. The disassembly and assembly process is likely to cause loss of structural parts, and the cleaning process may cause irreversible damage to the parts, even leading to the scrapping of the whole machine. Therefore, the existing chopping board disinfection machines cannot be effectively cleaned while ensuring the service life. Summary of the Utility Model

[0021] Beneficial effects: For the disinfection device of the present utility model, by providing a second chamber and the second chamber communicating with the first chamber, the disinfectant solution stored in the first chamber can enter the second chamber for buffer storage. When the disinfectant solution needs to be sprayed, the pumping member extracts the disinfectant solution in the second chamber to disinfect the accommodation chamber. On the one hand, both the first chamber and the second chamber can store the disinfectant solution, expanding the volume for storing the disinfectant solution. On the other hand, the second chamber serves as a buffer storage area for the disinfectant solution, forming a liquid pressure that is beneficial for the pumping member to extract the disinfectant solution, making the spraying of the disinfectant solution more uniform and improving the disinfection effect.

[0022] In an optional embodiment, the disinfection mechanism further includes a third chamber. The third chamber is disposed at the bottom of the housing.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0042] The following will describe Figures 1-5 , the embodiments of the disinfection device of the present utility model.

[0043] According to an embodiment of the present utility model, in a first aspect, a disinfection device is provided for disinfecting an item to be disinfected. The disinfection device includes: a housing 1, an environmental detection component 2, an item detection mechanism, a disinfection mechanism, and a control unit. The housing 1 has an accommodation cavity inside. The environmental detection component 2 is arranged on the housing 1 and is used for detecting environmental data at the position where the disinfection device is located. The item detection mechanism is arranged on the housing 1 and is used for detecting whether an item to be disinfected is placed in the accommodation cavity. The disinfection mechanism is arranged on the housing 1 and is used for spraying disinfectant into the accommodation cavity. The control unit is arranged on the housing 1. The signal input port of the control unit is electrically connected to the environmental detection component 2 and the item detection mechanism, and the signal output port of the control unit is electrically connected to the disinfection mechanism.

[0044] In this disinfection device, by arranging the disinfection mechanism on the housing 1, it is possible to directly spray disinfectant inside the accommodation cavity of the housing 1 to achieve disinfection and sterilization of the accommodation cavity. Compared with the existing disassembly and cleaning method, this disinfection device does not need to disassemble the whole machine, can not only achieve effective disinfection, but also will not have an adverse impact on the components of the whole machine, and can ensure the service life of the disinfection device. Moreover, by arranging the environmental detection component, it is possible to detect environmental data at the position where the disinfection device is located, such as temperature, humidity, etc., so as to set disinfection operation parameters according to the environmental data to achieve more accurate and effective disinfection and improve the disinfection effect. In addition, by arranging the item detection mechanism, it is possible to know whether an item to be disinfected (such as a cutting board, a knife, etc.) is placed in the accommodation cavity, so as to avoid the situation of damaging or affecting the item to be disinfected when disinfecting and sterilizing the accommodation cavity while placing the item to be disinfected in the accommodation cavity, and improve the reliability and safety of the functions of the disinfection device.

[0045] The disinfection device of the present application can be a cutting board disinfection machine, a dishwasher, etc. In this embodiment, the disinfection device is specifically a cutting board disinfection machine, which can disinfect and sterilize common tableware such as cutting boards, knives, chopsticks, spoons, etc. In this embodiment, cutting boards, knives, chopsticks, spoons, etc. are referred to as items to be disinfected.

[0046] The housing 1 is a load-bearing structure of the disinfection device and has a certain structural strength to facilitate the setting of other components and devices of the disinfection device. Generally, the housing 1 should be made of corrosion-resistant and high-temperature-resistant materials. The shape of the housing 1 can be set according to the product design requirements of the disinfection device. For example, in order to disinfect a cutting board, the housing 1 should have a certain height, width, etc. to facilitate accommodating the cutting board and disinfecting it. As Figures 1-2 shown, in order to make the disinfection device more stable, a support block 19 is arranged at the bottom of the housing 1 so that the disinfection device can be set more stably on a platform such as a tabletop.

[0047] The shell 1 has a accommodating cavity inside, the size of which matches the items to be sterilized. In order to facilitate the placement of different items to be sterilized (such as cutting boards, knives, chopsticks, spoons, etc.), placement positions for various items to be sterilized can be pre-planned in the accommodating cavity.

[0048] In addition, the outside of the housing 1 is provided with a power button 12, a display screen 13 and a disinfection button 14, and the power button 12, the display screen 13 and the disinfection button 14 are all electrically connected to the control unit. In the present embodiment, the power button 12 is arranged on the side of the housing 1 facing the user, and the user can start the disinfection device by touching or pressing the power button 12 to disinfect the items to be disinfected. The disinfection button 14 is arranged on the side of the housing 1 facing the user, and the user can start the self-disinfection function of the disinfection device by touching or pressing the disinfection button 14, that is, disinfect the accommodating cavity of the disinfection device. The display screen 13 is also arranged on the side of the housing 1 facing the user, and the current operating status of the disinfection device can be displayed on the display screen 13, which is convenient for the user to operate the disinfection device.

[0049] The environment detection part 2 is used to detect the environmental data of the location of the disinfection equipment. In the present embodiment, the environment detection part 2 detects the external environment data of the location of the disinfection equipment, and the environmental data include temperature, humidity, etc. This is because the problem of bacteria breeding, mold and odor in the holding chamber of the cutting board disinfection machine is closely related to the environment in which it is located. If the environment in which the cutting board disinfection machine is located is relatively dry, the situation of bacteria breeding, mold and odor will be reduced a lot. If the environment in which the cutting board disinfection machine is located is relatively dark and humid, the situation of bacteria breeding, mold and odor will be greatly increased. Therefore, by detecting the environmental data of the location of the disinfection equipment, the degree of bacteria breeding, mold and odor can be calculated, and the formulation of subsequent disinfection operation parameters can be provided. The environment detection part 2 is equipped with a sensor for identifying the ambient temperature and humidity, which can identify the ambient temperature and humidity of the surrounding environment in which the disinfection equipment is located. The environment detection part 2 is similar to an electronic thermo-humidifier.

[0050] Specifically, the environmental detection component 2 can identify the surrounding environment, calculate the bacteria that may be produced in the environment, and transmit the environmental data to the control unit through the data transmission line to provide a basis for subsequent disinfection work, such as how much disinfectant should be sprayed on rainy days, and what degree of drying and ultraviolet disinfection should be adopted.

[0051] Of course, in other embodiments, according to different design requirements, the environment detection component 2 can also detect the internal environment data of the housing cavity 1 to facilitate subsequent control.

[0052] The article detection mechanism is used to detect whether there is an article to be disinfected placed in the accommodation cavity. Since the main function of the disinfection device is to disinfect the article to be disinfected, when there is an article to be disinfected placed in the accommodation cavity of the disinfection device, the disinfection operation cannot be directly performed on the accommodation cavity of the disinfection device, otherwise it is easy to have an adverse impact on the article to be disinfected, such as damaging the article to be disinfected or affecting the safety of the subsequent use of the article to be disinfected, etc.

[0053] The disinfection mechanism is used to spray disinfectant liquid into the accommodation cavity to perform a disinfection operation on the interior of the accommodation cavity. The disinfection operation parameters of the disinfection mechanism are formulated based on the environmental data detected by the environmental detection component 2.

[0054] The control unit is used to control the overall operation of the disinfection device. The control unit formulates appropriate disinfection operation parameters by obtaining the environmental data detected by the environmental detection component 2. The control unit also obtains information on whether there is an article to be disinfected placed in the current accommodation cavity through the article detection mechanism. When there is no article to be disinfected placed in the accommodation cavity of the disinfection device, the control unit controls the disinfection mechanism to perform a disinfection operation on the accommodation cavity according to the formulated disinfection operation parameters.

[0055] Furthermore, the article detection mechanism is a gravity detection mechanism. This detection principle of using gravity for article detection is relatively simple, making it easy to set up the article detection mechanism and having high detection accuracy.

[0056] Furthermore, the article detection mechanism includes a first induction plate 3 and a first elastic member 4. One end of the first elastic member 4 is connected to the first induction plate 3, and the other end is connected to the bottom of the housing 1. When the article to be disinfected is placed in the accommodation cavity, the gravity of the article to be disinfected acts on the first induction plate 3. When the gravity of the article to be disinfected disappears, the article detection mechanism sends a detection signal to the control unit.

[0057] Such as Figures 3-4 As shown, the article detection mechanism is arranged in the accommodation cavity of the housing 1. The first induction plate 3 and the first elastic member 4 are arranged at the lower position of the accommodation cavity. One end of the first elastic member 4 is connected to the first induction plate 3, and the other end is connected to the bottom of the housing 1. Specifically, the upper end of the first elastic member 4 is connected to the first induction plate 3, and the lower end is connected to the bottom of the housing 1. Optionally, the first induction plate 3 is arranged horizontally, and the axial direction of the first elastic member 4 is arranged vertically.

[0058] In this embodiment, two first elastic members 4 are provided, and the two first elastic members 4 are arranged at an interval to effectively support the first induction plate 3. When the item to be disinfected is placed in the accommodation cavity, the gravity of the item to be disinfected acts on the first induction plate 3, causing the first induction plate 3 to move downward, and the first elastic member 4 is compressed by the force. When the item to be disinfected is removed from the accommodation cavity, that is, the gravity of the item to be disinfected disappears, the acting force on the first induction plate 3 and the first elastic member 4 disappears, the first elastic member 4 resumes its length, driving the first induction plate 3 to move upward. At this time, the item detection mechanism will send a detection signal to the control unit.

[0059] Furthermore, the item detection mechanism further includes a second induction plate 5, a second elastic member 6 and a connecting rod 7. One end of the second elastic member 6 is connected to the second induction plate 5, and the other end is connected to the top of the housing 1. The first induction plate 3 and the second induction plate 5 are connected by the connecting rod 7, and at least part of the item to be disinfected is hung on the second induction plate 5.

[0060] In this embodiment, the second induction plate 5 and the second elastic member 6 are arranged at the upper position of the accommodation cavity. One end of the second elastic member 6 is connected to the second induction plate 5, and the other end is connected to the top of the housing 1. Specifically, the lower end of the second elastic member 6 is connected to the second induction plate 5, and the upper end is connected to the top of the housing 1. Optionally, the second induction plate 5 is arranged horizontally, and the axial direction of the second elastic member 6 is arranged vertically. In this embodiment, two second elastic members 6 are provided, and the two second elastic members 6 are arranged at an interval to effectively pull the second induction plate 5.

[0061] The second induction plate 5 is suitable for hanging items to be disinfected, such as knives, chopsticks, spoons, etc. Of course, according to its load-bearing capacity, a cutting board can also be directly hung on the second induction plate 5. The first induction plate 3 and the second induction plate 5 are connected by the connecting rod 7. Specifically, the upper end of the connecting rod 7 is connected to the second induction plate 5, and the lower end of the connecting rod 7 is connected to the first induction plate 3. The connecting rod 7 is of a straight rod structure. When the item to be disinfected is hung on the second induction plate 5, the second induction plate 5 moves downward under the action of gravity, the connecting rod 7 moves downward, and then the first induction plate 3 moves downward. At the same time, the second elastic member 6 is stretched and the first elastic member 4 is compressed. When the item to be disinfected is removed from the second induction plate 5, the second induction plate 5 is no longer stressed. Under the restoring force of the second elastic member 6 and the first elastic member 4, the second induction plate 5 moves upward, the connecting rod 7 moves upward, and the first induction plate 3 moves upward.

[0062] In this embodiment, the item detection mechanism is connected to a switch wire. For example, the first induction plate 3 is connected to the switch wire. When the first induction plate 3 moves upward, it can close the switch wire, making the switch closed, thereby sending a detection signal to the control unit, that is, there is no item to be disinfected placed in the accommodation cavity at this time.

[0063] Further, the disinfection mechanism includes a first chamber 8 and a pumping member 9. The first chamber 8 is detachably connected to the housing 1. The first chamber 8 is used for storing the disinfectant solution. The pumping member 9 is arranged in the housing 1. There is an ejection port 101 inside the housing 1. The pumping member 9 communicates with the first chamber 8 and the ejection port 101.

[0064] In this embodiment, the disinfection mechanism is arranged at the lower position of the housing 1. The first chamber 8 is detachably connected to the housing 1. There is an ejection port 101 inside the housing 1. The pumping member 9 communicates with the first chamber 8 and the ejection port 101. The pumping member 9 can extract the disinfectant solution in the first chamber 8 to the ejection port 101 to spray the disinfectant solution into the accommodation chamber.

[0065] In this embodiment, the pumping member 9 is specifically a pump. The volume of the first chamber 8 can be set according to the overall dimensions of the machine and requirements. The disinfectant solution can be selected from Haisi Hainuo alcohol disinfectant solution, slightly acidic hypochlorous acid disinfectant solution, etc.

[0066] Further, the disinfection mechanism further includes a second chamber 10. The second chamber 10 communicates with the first chamber 8. The pumping member 9 communicates with the first chamber 8 through the second chamber 10.

[0067] In this embodiment, the second chamber 10 is detachably connected to the housing 1. The second chamber 10 communicates with the first chamber 8. The disinfectant solution stored in the first chamber 8 can enter the second chamber 10. The pumping member 9 communicates with the first chamber 8 through the second chamber 10. The pumping member 9 can extract the disinfectant solution in the second chamber 10 to the ejection port 101 and spray it into the accommodation chamber. In this embodiment, the disinfectant solution is sprayed onto the inner wall of the accommodation chamber to disinfect the accommodation chamber comprehensively.

[0068] The function of the first chamber 8 is to store the disinfectant solution. The function of the second chamber 10 is mainly to provide the disinfectant solution for disinfecting the accommodation chamber. Moreover, setting the second chamber 10 can also increase the volume of the stored disinfectant solution and reduce the frequency of replenishing the disinfectant solution. In this embodiment, the volume of the second chamber 10 is smaller than that of the first chamber 8. Setting the second chamber 10 is beneficial to balancing the liquid pressure during the extraction process of the pumping member 9 and making the spraying of the disinfectant solution more uniform.

[0069] The ejection port 101 is arranged at the middle position of the bottom of the accommodation chamber. As Figure 4 shown, the flow rate of the disinfectant solution sprayed by the pumping member 9 increases from small to large. When the pumping member 9 starts to spray the disinfectant solution, the disinfectant solution sprays out from the ejection port 101 and sprays upward. When the flow rate of the disinfectant solution increases to a certain extent, a disinfectant solution circulation as shown in Figure 4 is formed inside the accommodation chamber ( Figure 4 the arrow direction in is the circulation flow direction of the disinfectant solution). Since in this embodiment, the internal structure of the accommodation chamber is a symmetric structure (the axis of symmetry is Figure 4(the vertical center line at the shown angle), therefore, when the flow rate of the disinfectant liquid increases to a certain extent, the circulation path of the disinfectant liquid is also a symmetric circulation path, so that the disinfectant liquid can be sprayed to each angle of the accommodation cavity, making the disinfection effect better.

[0070] Furthermore, the disinfection mechanism further includes a third chamber 11, the third chamber 11 is arranged at the bottom of the housing 1, the third chamber 11 is used for collecting the recycled disinfection waste liquid, and the third chamber 11 is communicated with the accommodation cavity.

[0071] In this embodiment, the first chamber 8 and the third chamber 11 are respectively arranged on both sides of the extraction member 9, and the volume of the third chamber 11 is equivalent to that of the first chamber 8 to collect the disinfection waste liquid after disinfection. Optionally, the third chamber 11 is also detachably connected to the housing 1 to facilitate the user to pour and clean the disinfection waste liquid.

[0072] The first chamber 8, the second chamber 10 and the third chamber 11 are all detachably connected to the housing 1, which is convenient for the user to supplement or clean the disinfectant liquid, and does not affect the functional integrity and normal operation of the core components of the whole machine.

[0073] Furthermore, a waste liquid discharge port 102 is provided inside the housing 1, and the third chamber 11 is communicated with the accommodation cavity through the waste liquid discharge port 102.

[0074] A waste liquid discharge port 102 is arranged inside the housing 1 and near the bottom. After the disinfectant liquid disinfects the inner wall of the accommodation cavity, the disinfectant liquid becomes disinfection waste liquid, and the disinfection waste liquid flows to the third chamber 11 through the waste liquid discharge port 102 for storage, so as to facilitate subsequent cleaning by the user. By providing the third chamber 11, the used disinfection waste liquid can be recycled and stored, without an external discharge pipeline, simplifying the structure setting, and at the same time preventing insects and the like from easily entering the accommodation cavity through the discharge pipeline due to the setting of the discharge pipeline. The number of the waste liquid discharge ports 102 is set according to the internal size of the accommodation cavity. In this embodiment, four waste liquid discharge ports 102 are provided, and the four waste liquid discharge ports 102 are arranged at intervals, and the four waste liquid discharge ports 102 are all communicated with the third chamber 11. The four waste liquid discharge ports 102 can be communicated with each other or not.

[0075] Furthermore, the waste liquid discharge port 102 is a stepped discharge port, the waste liquid discharge port 102 includes a first discharge part 1021 and a second discharge part 1022 which are communicated with each other, the first discharge part 1021 is closer to the accommodation cavity than the second discharge part 1022, and the flow-through area of the first discharge part 1021 is larger than that of the second discharge part 1022.

[0076] In this embodiment, the waste liquid discharge port 102 includes a first discharge portion 1021 and a second discharge portion 1022 that are in communication with each other. The first discharge portion 1021 is closer to the accommodation cavity than the second discharge portion 1022. The flow-through area of the first discharge portion 1021 is larger than that of the second discharge portion 1022, forming a stepped discharge port. The disinfected waste liquid first enters the first discharge portion 1021 and then enters the second discharge portion 1022. Since the flow-through area of the first discharge portion 1021 is larger than that of the second discharge portion 1022, when there is a large amount of disinfected waste liquid, this waste liquid discharge port structure is beneficial to alleviating the discharge pressure of the waste liquid discharge port 102. The first discharge portion 1021 can form a certain buffer for the waste liquid discharge process, slowing down the blockage that may occur at the waste liquid discharge port 102 during the centralized collection of disinfected waste liquid, which is beneficial to ensuring the efficient recovery of disinfected waste liquid.

[0077] Furthermore, the disinfection device of this embodiment further includes a drying mechanism and / or an ultraviolet disinfection mechanism. The drying mechanism and the ultraviolet disinfection mechanism are arranged on the housing. The drying mechanism is used to dry the accommodation cavity, and the ultraviolet disinfection mechanism is used to perform ultraviolet disinfection on the accommodation cavity.

[0078] According to different usage requirements, the drying mechanism and the ultraviolet disinfection mechanism can be selectively arranged, such as only arranging the drying mechanism, only arranging the ultraviolet disinfection mechanism, or arranging both the drying mechanism and the ultraviolet disinfection mechanism at the same time. In this embodiment, the housing 1 is provided with a drying mechanism and an ultraviolet disinfection mechanism. The drying mechanism is used to dry the accommodation cavity, and the ultraviolet disinfection mechanism is used to perform ultraviolet disinfection on the accommodation cavity. When the disinfection device has a drying mechanism and an ultraviolet disinfection mechanism, the control unit is also electrically connected to the drying mechanism and the ultraviolet disinfection mechanism. The control unit can calculate the operating parameters of the drying mechanism and the ultraviolet disinfection mechanism according to the environmental data.

[0079] Specifically, the drying mechanism includes drying heating tubes 17. In order not to occupy too much internal space of the accommodation cavity, the drying heating tubes 17 are close to the two side walls of the accommodation cavity, and the length direction of the drying heating tubes 17 is arranged in the vertical direction. After the accommodation cavity is disinfected with disinfectant, the drying heating tubes 17 are started to dry the inside of the accommodation cavity to dry the remaining disinfectant and make the inside of the accommodation cavity dry.

[0080] The ultraviolet disinfection mechanism includes an ultraviolet module 15, which uses the ultraviolet disinfection characteristic to further disinfect and sterilize the inside of the accommodation cavity. A number of ultraviolet lamp beads 16 are arranged on the ultraviolet module 15. In this embodiment, four ultraviolet modules 15 are provided. The four ultraviolet modules 15 are divided into two groups and are arranged on the opposite inner walls of the accommodation cavity. The two ultraviolet modules 15 on the same inner wall of the accommodation cavity are arranged at intervals. The number of ultraviolet lamp beads 16 arranged is set according to the size of the whole machine accommodation cavity, and this embodiment does not limit this.

[0081] Such asFigure 5 As shown in the figure, this embodiment also provides a disinfection method, which is applied to the above-mentioned disinfection device. The disinfection method includes:

[0082] S01, activate the disinfection function;

[0083] S02, obtain environmental data;

[0084] S03, obtain disinfection operation parameters according to the environmental data;

[0085] S04, determine whether there are items to be disinfected placed in the accommodation cavity of the disinfection device;

[0086] S05, if yes, end the disinfection function;

[0087] S06, if no, then spray disinfectant into the accommodation cavity according to the disinfection operation parameters.

[0088] The disinfection method of this embodiment can set appropriate disinfection operation parameters according to environmental data, and when there are no items to be disinfected placed in the accommodation cavity, comprehensively disinfect the interior of the accommodation cavity of the housing 1. Compared with the existing disassembly and cleaning method, the disinfection method of this application does not require disassembly of the whole machine, can not only achieve effective disinfection, but also will not have an adverse impact on the components of the disinfection device, can ensure the service life and disinfection effect of the disinfection device, and is easy to operate, with good user experience.

[0089] The following is a detailed description of the disinfection method of this embodiment:

[0090] S01, activate the disinfection function;

[0091] This disinfection function refers to the self-disinfection function of the disinfection device for the interior of its accommodation cavity. When the user needs to disinfect the interior of the disinfection device, if the disinfection device is not powered on at this time, it is necessary to touch or press the power-on button 12 to start the disinfection device, and then touch or press the disinfection button 14 to start the self-disinfection function of the disinfection device. If the disinfection device has been powered on and started at this time, the user can touch or press the disinfection button 14 to start the self-disinfection function of the disinfection device.

[0092] Setting the activation of the disinfection function to manual mode is to give the user the operating space to select the function. The user can start this function by himself when he thinks it is necessary to disinfect the disinfection device.

[0093] S02, obtain environmental data;

[0094] The environment where the disinfection device is located is detected by the environmental detection component 2 to obtain environmental data, such as temperature and humidity, etc. The environmental data detected by the environmental detection component 2 is sent to the control unit.

[0095] S03, obtain disinfection operation parameters according to the environmental data;

[0096] Based on the environmental data detected by the environmental detection component 2, the control unit determines the surrounding environment, calculates the data of possible bacterial conditions, obtains the disinfection operation parameters, transmits the disinfection operation parameters to the disinfection mechanism, transmits the drying operation parameters to the drying mechanism, and transmits the ultraviolet operation parameters to the ultraviolet disinfection mechanism to provide a basis for their work.

[0097] The relationships between the environmental data and the disinfection operation parameters, drying operation parameters, and ultraviolet operation parameters are, for example:

[0098] Assume that when the temperature is constant, at a temperature of 25°C and a humidity of 80%, the amount of disinfectant is 100 ml, the drying duration is 10 min, and the ultraviolet is linear / 60 nm; at a temperature of 25°C and a humidity of 90%, the amount of disinfectant is 200 ml, the drying duration is 20 min, and the ultraviolet is linear / 80 nm. Because the higher the humidity, the more bacteria will breed, and the disinfection-related working values (disinfection operation parameters) will increase accordingly.

[0099] Assume that when the humidity is constant, at a temperature of 20°C and a humidity of 80%, the amount of disinfectant is 200 ml, the drying duration is 20 min, and the ultraviolet is linear / 80 nm; at a temperature of 30°C and a humidity of 80%, the amount of disinfectant is 100 ml, the drying duration is 10 min, and the ultraviolet is linear / 60 nm. Because the lower the temperature, the higher the survival probability of the bacteria that breed, and the disinfection-related working values (disinfection operation parameters) will increase accordingly.

[0100] S04, determine whether there are items to be disinfected placed in the accommodation cavity of the disinfection equipment;

[0101] The item detection mechanism determines whether there are items to be disinfected, such as cutting boards, knives, etc., currently placed in the accommodation cavity. In this embodiment, the gravity sensing technology is used to determine whether there are items to be disinfected in the accommodation cavity.

[0102] S05, if so, end the disinfection function;

[0103] If there are items to be disinfected in the accommodation cavity, the first induction plate 3 and the second induction plate 5 are in the lower position, and the item detection mechanism will not send a detection signal to the control unit, and the disinfection function will end.

[0104] S06, if not, then spray disinfectant into the accommodation cavity according to the disinfection operation parameters.

[0105] If there are no items to be disinfected in the accommodation cavity, the first induction plate 3 and the second induction plate 5 are in the upper position, and the item detection mechanism sends a detection signal to the control unit to activate the disinfection mechanism.

[0106] The disinfection mechanism starts to work. The extraction part 9 extracts the disinfectant liquid and sprays it into the accommodation cavity through the spraying orifice 101. When the extraction part 9 just starts to spray the disinfectant liquid, the disinfectant liquid sprays out from the spraying orifice 101 and sprays upward. When the flow rate of the disinfectant liquid increases to a certain extent, a disinfectant liquid circulation path as shown in Figure 4 is formed inside the accommodation cavity, that is, after the disinfectant liquid sprays out from the spraying orifice 101, it first flows to both left and right sides, then the disinfectant liquid sprays upward to the top of the accommodation cavity, and then the disinfectant liquid flows to the middle position. The disinfectant liquids on both left and right sides contact at the middle position and then flow downward. At this time, the disinfectant liquid becomes disinfected waste liquid and enters the waste liquid discharge orifice 102, and then enters the third chamber 11 for recycling. During the above process, the disinfectant liquid disinfects and sterilizes all corners of the inner wall of the accommodation cavity.

[0107] Further, after the step of spraying the disinfectant liquid into the accommodation cavity according to the disinfection operation parameters if it is not, it further includes starting the drying mechanism to dry the accommodation cavity. After the disinfectant liquid disinfects the accommodation cavity, the drying mechanism can be started to dry the residual disinfectant liquid in the accommodation cavity according to the drying operation parameters to make the inside of the accommodation cavity dry.

[0108] Further, after the step of starting the drying mechanism to dry the accommodation cavity, it further includes starting the ultraviolet disinfection mechanism to perform ultraviolet disinfection on the accommodation cavity. After the drying is completed, the ultraviolet disinfection mechanism can also be started to further disinfect and sterilize the accommodation cavity according to the ultraviolet operation parameters to improve the disinfection effect.

[0109] The disinfection equipment and disinfection method of this embodiment adopt the inner cavity disinfection technology of the fuselage. The environmental detection part 2 detects the environment around the disinfection equipment to provide data basis for the fuselage disinfection function. The article detection mechanism detects whether the article to be disinfected is taken out of the accommodation cavity, so as to activate the fuselage disinfection function. By using the fuselage circulation cleaning and disinfection technology of the disinfection mechanism, cooperating with the drying mechanism and the ultraviolet disinfection mechanism, it improves the accuracy and thoroughness of disinfection, and effectively solves the problems of bacteria breeding, mildew and bad smell in the inner accommodation cavity of the disinfection equipment.
