This minimizes the difference in distance between each exhaust port and the heating mechanism, thereby ensuring a more uniform temperature throughout the disinfection chamber and improving the disinfection effect. Furthermore, the more uniform temperature throughout the disinfection chamber also prevents the formation of locally overheated areas, thus preventing damage to the items to be disinfected from high temperatures.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0041] All terms used herein, including technical and scientific terms, have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0042] When using expressions such as "at least one of A, B, and C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, and C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C. Similarly, when using expressions such as "at least one of A, B, or C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, or C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C.

[0043] Disinfection equipment is widely used in homes and businesses for the daily disinfection of items such as tableware, kitchen utensils, and baby products. One common method involves introducing hot air and / or steam into the disinfection chamber of the equipment to disinfect items at high temperatures.

[0044] To disinfect as many items as possible in a single disinfection process, existing disinfection equipment often has multiple installation locations. Each location (or nearby) is equipped with exhaust vents for hot air and / or hot steam to create a high-temperature disinfection environment inside and / or outside the items. Due to the limited placement of the heating mechanism within the disinfection equipment, the airflow path length from the exhaust vents to the heating mechanism often varies. This results in significant temperature differences in the hot air and / or hot steam discharged through the exhaust vents. Specifically, the temperature near the exhaust vents closer to the heating mechanism is higher, while the temperature near the exhaust vents farther away is lower.

[0045] Therefore, the temperature within the sterilization chamber becomes uneven, with warmer areas achieving better sterilization and cooler areas performing poorly. Furthermore, the concentrated heat in the warmer areas can damage the items being sterilized. For example, baby products such as bottles, nipples, tableware, and teethers often use polymer materials (such as PP (polypropylene), PPSU (polyphenyl sulfone resin), and TRITAN) to meet the requirements of being non-toxic, odorless, and safe. Compared to glass and ceramics, these materials are softer and lighter, but have poorer heat resistance (generally only able to withstand temperatures between 100°C and 200°C). Excessive heat can cause deformation or damage to these products.

[0046] In view of this, how to provide a disinfection device that can make the temperature of each part of the disinfection chamber more uniform, so as to improve the disinfection effect and prevent the formation of local high temperature zones has become an urgent technical problem to be solved.

[0047] Figure 1 A schematic diagram of the air duct of a disinfection device according to an embodiment of the present invention is shown.

[0048] According to the disinfection equipment provided by this utility model, refer to Figure 1 As shown, the device includes a housing 1, an air duct 2, an air generating mechanism 6, and a heating mechanism 4. The housing 1 defines a disinfection chamber. The air duct 2 is disposed within the housing 1. The air generating mechanism 6 is configured to generate a directional airflow within the air duct 2. The heating mechanism 4 is disposed within the air duct 2 to heat the airflow passing through it. The bottom of the disinfection chamber has at least two exhaust ports 3 communicating with the air duct 2. Along the extending direction of the air duct 2, the ratio of the path length of the airflow path between each exhaust port 3 and the heating mechanism 4 to the average path length is configured to be greater than or equal to 0.7 and less than or equal to 1.3. The path length can be characterized as the shortest distance from the midpoint of the exhaust port 3 along the extending direction of the air duct 2 to the heating mechanism 4.

[0049] In some illustrative embodiments, reference is made to Figure 1 As shown, the air duct 2, the air generating mechanism 6, and the heating mechanism 4 are all located at the bottom of the housing 1. The housing 1 may be constructed as a cube, with its bottom correspondingly configured as a roughly rectangular structure. Specifically, the air generating mechanism 6 is located on one side of the bottom of the housing 1 (see reference). Figure 1 (as shown above in the Y direction), air duct 2 is located on the other side of the bottom of housing 1 (refer to...). Figure 1 (As shown in the lower part of the Y direction), the heating mechanism 4 is located between the air outlet of the air generating mechanism 6 and the air inlet of the air duct 2. The air generating mechanism 6 includes, but is not limited to, a fan, an air pump, or any other mechanism suitable for generating airflow when installed inside the housing 1; the heating mechanism 4 includes, but is not limited to, an electric heating wire, an electric heating rod, an electric heating plate, or any other mechanism suitable for heating the airflow.

[0050] In some illustrative embodiments, the bottom of the housing 1 is provided with n exhaust ports, where n≥2, and the path length of each exhaust port along the air duct extension direction of the heating mechanism 4 is L. kn The average wind path length is, Formula 1.

[0051] Furthermore, the ratio of the distance from each exhaust port to the heating unit 4 to the average airflow path length is configured as follows: Equation 2.

[0052] Reference Figure 1In the illustrative embodiment shown, the bottom of the housing 1 includes, but is not limited to, six exhaust vents. The path lengths of the six exhaust vents and the heating mechanism 4 along the extension direction of the corresponding air ducts are L, respectively. k1 L k2 L k3 L k4 L k5 and L k6 ;

[0053] The average wind path is ;

[0054] Among them, L k1 L k2 L k3 L k4 L k5 and L k6 All satisfy equation 2 above, that is, L k2 L k3 L k4 L k5 and L k6 With L k1 Similarly, I will not elaborate further.

[0055] In this embodiment, along the extension direction of the air duct provided in the disinfection equipment, the ratio of the length of the air path between the exhaust port and the heating mechanism 4 to the average length of the air path is configured to be greater than or equal to 0.7 and less than or equal to 1.3. This makes the distance between each exhaust port 3 and the heating mechanism 4 relatively close, thus ensuring a more uniform temperature in all parts of the disinfection chamber and improving the disinfection effect. Furthermore, the more uniform temperature in all parts of the disinfection chamber also prevents the formation of locally excessively high-temperature zones, thereby preventing damage to the items 10 to be disinfected from high temperatures. It should be understood that the embodiments of this utility model are not limited to this.

[0056] For example, the heating mechanism 4 can also be located in the middle of the bottom of the box 1, and the air duct 2 is distributed radially from the heating mechanism 4 to the outer side of the bottom of the box 1.

[0057] Alternatively, the number of exhaust ports 3 located at the bottom of the housing 1 can be 2, 3, 4, 5, 6, 7, 8, 9, 10, or any other number.

[0058] According to an embodiment of the present invention, the ratio of the length of the air path between the exhaust port and the heating mechanism 4 to the average length of the air path can also be configured to be greater than or equal to 0.8 and less than or equal to 1.2; or, it can also be configured to be greater than or equal to 0.9 and less than or equal to 1.1.

[0059] According to an embodiment of the present invention, along the extension direction of the air duct 2, the air path length between each exhaust port 3 and the heating mechanism 4 is configured to be approximately the same.

[0060] In some illustrative embodiments, reference continues to be made to the reference. Figure 1 In the embodiment shown with six exhaust ports 3, the lengths of the six exhaust ports from the heating mechanism 4 along the extension direction of the corresponding air duct can be configured to be approximately the same, i.e., L k1 =L k2 =L k3 =L k4 =L k5 =L k6 The phrase "approximately the same" can be interpreted as meaning that, ideally, the lengths of the aforementioned wind path lines should be identical. However, unavoidable factors such as assembly errors and material deformation due to heat result in negligible length differences. In other words, the length of each wind path line can be configured to be equal to the average wind path line length.

[0061] In this implementation, when disinfection is performed using a disinfection device, since the distance between each exhaust port 3 and the heating mechanism 4 is the same, the temperature of the airflow discharged through each exhaust port 3 can be considered to be basically the same. This ensures that the temperature in the area near each exhaust port 3 within the disinfection chamber is also approximately the same, which helps to further improve temperature uniformity and prevent the formation of excessively high-temperature zones.

[0062] According to an embodiment of the present invention, referring to Figure 1 As shown, the disinfection equipment includes at least three exhaust ports. The ratio of the minimum distance between two adjacent exhaust ports 3 to the average distance between any two adjacent exhaust ports 3 is configured to be greater than or equal to 0.7 and less than or equal to 1.3.

[0063] In some illustrative embodiments, reference is made to Figure 1 As shown, the spacing between two adjacent exhaust ports 3 is configured to be greater than or equal to 30 mm and less than or equal to 120 mm.

[0064] In some illustrative embodiments, reference is made to Figure 1 As shown, the disinfection equipment includes, but is not limited to, having six exhaust ports 3. Specifically, the six exhaust ports 3 are arranged in the X or Y direction at the bottom of the disinfection chamber, and the distance between two adjacent exhaust ports 3 along the X direction is as follows: Figure 2 As shown in S1, the distance between two adjacent exhaust ports 3 along the Y direction is as follows: Figure 2Shown as S2. Further, there are m lines formed by every two adjacent exhaust ports 3 along the X direction or the Y direction. Among them, both S1 and S2 are configured to be greater than or equal to 30 millimeters and less than or equal to 120 millimeters, that is, 120mm ≥ S1 ≥ 30mm, and 120mm ≥ S2 ≥ 30mm. It should be understood that the embodiments of the present invention are not limited to this.

[0065] For example, the spacing between two adjacent exhaust ports 3 is configured to be greater than or equal to 40 millimeters and less than or equal to 110 millimeters; or, the spacing between two adjacent exhaust ports 3 is configured to be greater than or equal to 50 millimeters and less than or equal to 100 millimeters.

[0066] Again, for example, the spacing between two adjacent exhaust ports 3 can be configured to any value among 30 millimeters, 40 millimeters, 50 millimeters, 60 millimeters, 70 millimeters, 80 millimeters, 90 millimeters, 100 millimeters, 110 millimeters, and 120 millimeters.

[0067] Continue to refer to Figure 1 Shown in the figure, based on the above arrangement of 6 exhaust ports, there are 7 (i.e., m) lines formed by every two adjacent exhaust ports 3 along the X direction or the Y direction, so as to connect the 6 exhaust ports to form a "day" - shaped structure. Among these 7 lines, the lengths of 3 lines are S1 and the lengths of 4 lines are S2.

[0068] For this reason, based on Figure 1 the shown arrangement of the exhaust ports 3, the average spacing between every two adjacent exhaust ports 3 Equation 3. Further, S1 satisfies Equation 4. Similarly, S2 also correspondingly satisfies . It should be understood that the embodiments of the present invention are not limited to this. It should be understood that the embodiments of the present invention are not limited to this.

[0069] For example, the disinfection device can be provided with 3 exhaust ports 3. Among these three exhaust ports 3, there is a middle exhaust port, and one of the other two exhaust ports 3 is arranged in the X direction of the middle exhaust port, and the other is arranged in the Y direction of the middle exhaust port; in this arrangement, there are 2 lines formed by every two adjacent exhaust ports 3 along the X direction or the Y direction.

[0070] Or, for example, the disinfection device can be provided with four exhaust ports 3, and these four exhaust ports 3 are arranged in a rectangle and are respectively located at the four corners of the rectangular structure; in this arrangement, there are 4 lines formed by every two adjacent exhaust ports 3 along the X direction or the Y direction.

[0071] For example, in addition to being arranged along the X or Y direction, multiple exhaust ports 3 can also be arranged in an elliptical, circular or other array form. Based on different arrangement methods, the distance between two adjacent exhaust ports 3 should be the shortest distance of the line formed between them along the arrangement direction.

[0072] According to an embodiment of this utility model, the ratio of the minimum distance between two adjacent exhaust ports 3 to the average distance between any two adjacent exhaust ports 3 can be configured to be greater than or equal to 0.8 and less than or equal to 1.2; or, it can be configured to be greater than or equal to 0.9 and less than or equal to 1.1. It should be further noted that the ratio of the minimum distance between two adjacent exhaust ports 3 to the average distance between any two adjacent exhaust ports 3, and the ratio of the length of the air path between each exhaust port 3 and the heating mechanism 4 to the average length of the air path, can be configured to be the same or different.

[0073] According to an embodiment of the present invention, referring to Figure 1 As shown, the air duct 2 includes a main path and at least two branch paths, each branch path connecting to an exhaust port 3. Along the extension direction of the air duct 2, the path length of the airflow path at each exhaust port 3 and the branch location of the main path is configured to be approximately the same.

[0074] According to an embodiment of the present invention, referring to Figure 1 As shown, the bottom of the housing 1 is provided with multiple air ducts 2, namely the first air duct 21 and the second air duct 22 described below. Specifically, the first air duct 21 includes a first main path 211 and a branch located at the first main path 211 away from the heating mechanism 4. Through this branch location, the first air duct also has a first branch path 212 and a second branch path 213, each of which connects to a first exhaust port 31. Similarly, the second air duct 22 includes a second main path 221 and a branch located at the second main path 221 away from the heating mechanism 4. Through this branch location, the second air duct also has a third branch path 222 and a fourth branch path 223, each of which connects to a second exhaust port 32.

[0075] In this embodiment, at least a portion of the air duct 3 has a main path and branch paths radiating outward from the branch locations of the main path, with exhaust ports 3 located on each branch path. Since each branch path of the air duct 3 shares a main path, and the multiple branch paths are dispersed by the same branch locations, the path lengths of the exhaust ports 3 located on each branch path overlap in the main path portion. Based on this, by setting the distance between the exhaust ports 3 located on each branch path and the branch locations of the main path to be approximately the same, the design requirement that the path length of each air path is approximately the same can be met. In this embodiment, multiple branch paths converge on the same main path, thus reducing the number of main paths located at the bottom of the housing 1, which is beneficial for fully utilizing the bottom space of the housing; furthermore, since the number of main paths is designed to be smaller, it also means that the number of air inlets corresponding to each air duct is smaller, which allows the airflow output by the air-controlling mechanism 6 to be more concentrated, which is beneficial for increasing the airflow velocity within each air duct. It should be understood that the embodiments of this utility model are not limited to specific examples.

[0076] For example, the air duct 3 can also be provided with other numbers of branches, specifically three branches, four branches, five branches, six branches, and any other number of branches.

[0077] Figure 2 This is a schematic diagram of another illustrative embodiment of the exhaust port arrangement.

[0078] According to another embodiment of the present invention, referring to Figure 2 As shown, the disinfection equipment may also include at least two third air ducts 23, each of which is connected to an exhaust port 3.

[0079] In some illustrative embodiments, reference is made to Figure 2 As shown, the disinfection equipment is equipped with two third air ducts 23, each of which is connected to an exhaust port 3. Furthermore, the two exhaust ports 3 have the same path length in the third air ducts 23.

[0080] In this implementation, the third air duct 23 has only a main path, and the exhaust port 3 is located on the main path. Therefore, by distributing the main path into multiple branches as described in the above embodiment, the airflow can be concentrated in the third air duct 23, which helps maintain the flow velocity of the airflow discharged from the exhaust port 3. Of course, given the same number of exhaust ports at the bottom of the housing 1, this implementation has more third air ducts 23 than the above implementation with branches, thus occupying more bottom space. Therefore, in specific implementation scenarios, the use of a third air duct 23 with only a main path or a third air duct 23 with branches should be considered comprehensively. For example, some third air ducts 23 can have only a main path, while others can have branches. In this way, given the same flow rate and velocity of the airflow input at the air inlet of each third air duct 23, the gas discharged from different exhaust ports can have different flow velocities, thus applicable to the disinfection of different items.

[0081] For example, the exhaust port 3 with a higher flow rate can be used to disinfect items with a larger internal volume, while the exhaust port 3 with a lower flow rate can be used to disinfect items with a smaller internal volume. The airflow with a higher flow rate can spread to a wider area in items with a larger internal volume, while the airflow with a lower flow rate can spread to a narrower area in items with a smaller internal volume. This helps to ensure that the temperature inside each item to be disinfected is roughly the same, thereby maintaining temperature uniformity.

[0082] According to an embodiment of the present invention, referring to Figure 1 As shown, the disinfection equipment includes at least one first air duct 21 and at least one second air duct 22. A first exhaust port 31 communicating with the first air duct 21 and a second exhaust port 32 communicating with the second air duct 22 are arranged in an array at the bottom of the disinfection chamber. The array includes, but is not limited to, at least one of row arrays, column arrays, and ring arrays.

[0083] In some illustrative embodiments, reference is made to Figure 1 As shown, the bottom of the disinfection chamber has six exhaust ports 3, with adjacent two exhaust ports 3 arranged in either the X or Y direction. The exhaust ports 3 arranged along the X direction form the aforementioned row array, and the exhaust ports 3 arranged along the Y direction form the aforementioned column array. It should be understood that the embodiments of this utility model are not limited thereto.

[0084] For example, multiple exhaust ports 3 can also be arranged in a ring array, that is, the lines formed by the multiple exhaust ports can form a ring structure, or an approximate ring structure. Specifically, the ring structure can be one of the following: circular ring structure, elliptical ring structure, square ring structure, and other ring structures.

[0085] According to an embodiment of the present invention, referring to Figure 1As shown, the disinfection equipment includes at least two first air ducts 21, which are arranged axially and / or centrally symmetrically at the bottom of the housing 1.

[0086] According to an embodiment of the present invention, referring to Figure 1 As shown, the second air duct 22 is disposed between two adjacent first air ducts 21.

[0087] According to an embodiment of the present invention, referring to Figure 1 As shown, in the orthographic projection of the bottom of the sterilization chamber, the straight-line distance between the projection of the first exhaust port 31 and the projection of the heating mechanism 4 is less than that between the projection of the second exhaust port 32 and the projection of the heating mechanism 4. The first air duct 21 has at least one bend. The angle formed between the first extension direction of the first air duct 21 located upstream of the bend and the second extension direction located downstream of the bend (i.e., Figure 1 The β shown is configured as an acute angle or a right angle.

[0088] According to an embodiment of the present invention, referring to Figure 1 As shown, the second air duct 22 has at least one arc-shaped portion. The arc of the arc-shaped portion (i.e., Figure 1 The α shown is configured to be less than 90°.

[0089] In some illustrative embodiments, reference is made to Figure 1 As shown, the disinfection equipment has two first air ducts 21 and one second air duct 22. Specifically, the air inlets of the two first air ducts 21 and the one second air duct 22 are connected and are positioned facing the exhaust end of the air generating mechanism 6. Furthermore, the two first air ducts 21 are arranged symmetrically along the bottom of the housing 1 (which can be considered as the center line of the bottom), and the second air duct 21 is located between the two second air ducts.

[0090] In some illustrative embodiments, reference is made to Figure 1 As shown, the first air duct 21 includes a first main duct 211 and a branch located at the first main duct 211 away from the heating mechanism 4. Through this branch location, the first air duct also has a first branch 212 and a second branch 213, each of which is connected to a first exhaust port 31. Furthermore, the second air duct 22 includes a second main duct 221 and a branch located at the second main duct 221 away from the heating mechanism 4. Through this branch location, the second air duct also has a third branch 222 and a fourth branch 223, each of which is connected to a second exhaust port 32.

[0091] In some illustrative embodiments, reference is made to Figure 1 As shown, the air intake end of the first air duct 21 is along... Figure 1Extending in the Y direction and along the extension direction of the first air duct 21, the first main path 211 of the first air duct 21 has a first bend A1 (bending from the air inlet towards the X direction), a second bend A2 (bending from the first bend towards the Y direction), and a third bend A3 (bending again from the second bend towards the X direction) arranged sequentially. Furthermore, the third bend has a branch position, and from this branch position, a first branch 212 is formed along the Y direction towards the heating mechanism 4, and a second branch 213 is formed along the Y direction away from the heating mechanism 4.

[0092] Based on the above embodiments, continue to refer to Figure 1 As shown, the air intake end of the second air duct 22 is along... Figure 1 As shown, it extends in the Y direction, and the second main path 221 of the second air duct 22 also extends in the approximate Y direction away from the heating mechanism 4 (e.g. Figure 1 (As shown below) Extends. Further, the second main road 221 has branch locations, from which third branch roads 222 and fourth branch roads 223 bend outwards in the X direction, respectively. The third branch roads 222 and fourth branch roads 223 are configured in an arc shape.

[0093] In some illustrative implementations, continue to refer to Figure 1 As shown, multiple (such as) connected to the first air duct 21 Figure 1 The four first exhaust ports 31 shown, and multiple exhaust ports (such as the four shown) connected to the second air duct 22. Figure 1 The two second exhaust ports 32 shown are arranged in a row at the bottom of the housing 1 (as shown). Figure 1 (shown in the X direction) and column arrays (such as...) Figure 1 The arrangement of intervals (in the Y direction as shown). In such an embodiment, refer to... Figure 1 As shown, the two first air ducts 21 and the second air duct 22 are distributed in a roughly "hole" shape at the bottom of the housing 1, and the air inlets of the first air ducts 21 and the second air ducts 22 are connected. This facilitates the concentrated and compact arrangement of the air ducts 2 at the bottom of the housing 1, which helps to save bottom space. The first exhaust port 31 connected to the first air duct 21 and the second exhaust port 32 connected to the second air duct 22 are arranged in a row array and a column array at the bottom of the housing 1, so that the lines connecting the exhaust ports 3 form a roughly rectangular arrangement, thereby forming multiple uniformly distributed disinfection positions. When the items 10 are placed in the disinfection equipment, it helps to prevent the items 10 from being too compact and overlapping.

[0094] In addition, since the first exhaust port 31 is closer to the heating mechanism 4 than the second exhaust port 32, the bends in the first air duct 21 (i.e., the first bend A1, the second bend A2, and the third bend A3) actively extend the path length of the first air duct 1 and correspondingly reduce the airflow velocity within the air duct 2. The second exhaust port 32, being farther from the heating mechanism 4, is positioned as opposite as possible to the heating mechanism 4 and employs an arc-shaped branch structure to minimize airflow obstruction, thereby maintaining the airflow velocity within the second air duct 22. Through this design, the temperature and velocity of the airflow discharged through the first exhaust port 31 and the second exhaust port 32 are similar, resulting in uniform temperature throughout the disinfection chamber for effective disinfection of the items 10 within the chamber.

[0095] Figure 3 yes Figure 1 The diagram shows the disinfection equipment in its first position.

[0096] According to an embodiment of the present invention, referring to Figure 1 As shown, the air inlets of the first air duct 21 and the second air duct 22 are connected and located downstream of the air control mechanism 6.

[0097] According to an embodiment of the present invention, referring to Figure 1 and Figure 3 As shown, the disinfection equipment also includes a valve plate 5, which is adjustablely disposed at the air inlet end of the first air duct 21 and configured to move between a first position that closes the first air duct 21 and a second position that opens the first air duct 21.

[0098] In some illustrative embodiments, reference is made to Figure 1 As shown, the air inlets of the first air duct 21 and the second air duct 22 converge and are positioned facing the exhaust end of the air-controlling mechanism 6, so that the airflow enters the first air duct 21 and the second air duct 22 with a relatively high initial flow velocity. The air inlets of the two first air ducts 21 are located on both sides of the air inlet of the second air duct 22. Furthermore, the disinfection device has two valve plates 5, which are pivotally mounted at the air inlet of the second air duct 22, allowing them to swing between a first position and a second position.

[0099] In some illustrative embodiments, the two valve plates 5 are driven by, but are not limited to, an actuation mechanism, such as a motor suitable for driving the pivoting and synchronous rotation of the valve plates 5, or a push rod suitable for pushing (or pulling) the valve plates 5 to swing.

[0100] In other illustrative embodiments, the two valve plates 5 also have operating ends that are exposed outside the housing to swing when the user pushes the operating ends, thereby closing or opening at least one first air passage 21.

[0101] It should be noted that any actuation mechanism and operating end suitable for driving valve plate 5 can be selected and applied, and will not be elaborated further.

[0102] In this implementation, the first air duct 21 can be closed by operating the valve plate 5, thereby outputting the airflow generated by the air-generating mechanism 6 only through the second exhaust port 32 (i.e., the second air duct 22). Under the premise that the operating power of the air-generating mechanism 6 remains unchanged, the airflow output from the second exhaust port 32 has a faster velocity and a larger flow rate. This allows the disinfection equipment to have at least two operating states: when the valve plate 5 is in the second position, both the first air duct 21 and the second air duct 22 are open, and both the first exhaust port 31 and the second exhaust port 32 can be used to disinfect the items 10; when the valve plate is in the first position, the first air duct 21 is closed and the second air duct 22 is open, and the airflow in the second air duct 22 has a faster velocity and a higher flow rate, thus enabling rapid disinfection of items arranged at the second exhaust port 32.

[0103] Figure 4 A perspective view of a disinfection device according to an embodiment of the present invention is shown schematically. Figure 5 yes Figure 4 A partial enlarged view of the tray of the disinfection equipment shown. Figure 6 This is a diagram showing the usage status of items to be disinfected placed in the disinfection equipment.

[0104] According to an embodiment of the present invention, referring to Figures 4 to 6 As shown, the disinfection device also includes at least two trays 9. The trays 9 are located at the bottom of the housing 1, and each tray 9 has an exhaust port 3. According to an embodiment of the present invention, the disinfection device also includes an air guide pipe 8, which is located on at least a portion of the trays 9. The air guide pipe 8 communicates with the exhaust port 3 and protrudes from the trays 9 to guide the hot airflow into the items to be disinfected.

[0105] In some illustrative embodiments, reference is made to Figure 4 and Figure 5 As shown, one part of the storage tray 9 is connected to the first air duct 21, and the other part of the storage tray 9 is connected to the second air duct 22.

[0106] In some illustrative embodiments, reference is made to Figure 4 and Figure 5As shown, the housing 1 of the disinfection equipment includes, but is not limited to, a generally cubic structure, with a generally cubic disinfection chamber formed therein. Furthermore, the housing 1 may also be provided with a door 7 that can be opened and closed to allow the disinfection chamber to be opened or closed, thereby allowing the items 10 to be disinfected to be placed in or removed. The door 7 includes, but is not limited to, the following: Figure 4 As shown, it can be pivotally mounted on the housing 1, or it can be other structures mounted on the housing 1 that are detached from or can be pushed and pulled.

[0107] In one illustrative embodiment, the bottom of the housing 1 is along the row direction (e.g.) Figure 4 (as shown in the X direction) and column direction (e.g.) Figure 4 Multiple trays 9 are arranged at intervals in the Y direction (as shown). Specifically, each tray 9 has an exhaust port 3 formed in the center, which can be connected to the first air duct 21 or the second air duct 22 in the form of any of the above embodiments, thereby outputting hot air and / or hot steam transmitted by the air duct 2. Each tray 9 has a disinfection position defined at its upper part.

[0108] In this embodiment, the tray 9 is used to support the item 10 to be disinfected, and the exhaust port 3 is used to vent hot air and / or hot steam to the inside or outside of the item 10, thereby placing the item in a high-temperature environment for disinfection.

[0109] In some illustrative embodiments, reference is made to Figure 6 As shown, at least two air guide pipes 8 are provided, which include, but are not limited to, those connected to the second air passage 22 via the exhaust port 3. The upper end of each air guide pipe 8 extends upwards (along...) Figure 4 (Extending in the Z direction as shown), thereby making its exhaust position higher than the exhaust ports 3 provided by other storage trays 9. Furthermore, the air guide tube 8 can be detachably connected to the exhaust port 3 (e.g., using a pluggable air guide tube).

[0110] In this implementation method, refer to Figure 6 The first item 101 and the second item 102 shown can be placed upside down on the tray 9, with the open ends of the first item 101 and the second item 102 facing the tray 9, and fitted over the air duct 8. In this way, the air duct 8 extends into the interior of the item 2 to guide hot air and / or hot steam to the inside of the item 2, thereby achieving effective disinfection of the interior of the item 2. When the air duct 8 is removed, the hot air and / or hot steam output through the exhaust port 3 can be used to disinfect the outside of the item 2.

[0111] According to an embodiment of the present invention, referring to Figure 5 and Figure 6As shown, the exhaust port 3 is located in the middle of the storage tray 9, and multiple protrusions 91 are also provided around the exhaust port 3 at intervals to elevate the items to be disinfected, so that a gap is formed between the items and the storage tray 9.

[0112] In some illustrative embodiments, reference is made to Figure 5 and Figure 6 As shown, the protrusions 91 are evenly spaced around the exhaust port 3. In detail, the protrusions 91 extend, but are not limited to, along the radial direction of the tray 9 to increase its support range.

[0113] In this implementation method, refer to Figure 5 and Figure 6 As shown, the protrusion 91 is adapted to support the article 2 so that a gap is formed between the opening of the article 2 and the upper end face of the tray 9, so that hot air and / or hot steam can be discharged through the gap after disinfecting the interior of the article 2, preventing the hot air and / or hot steam from being unable to enter due to excessive pressure inside the article 2.

[0114] In some illustrative embodiments, reference is made to Figure 5 and Figure 6 As shown, the upper surface of the storage tray 9 is also equipped with an auxiliary disinfection mechanism. This auxiliary disinfection mechanism can disinfect the item 2 using methods other than thermal disinfection, such as using an ultraviolet (UV) generator 92. Specifically, the UV generator 92 is positioned facing the item 2 to irradiate it with UV light upon activation, thereby disinfecting any residual substances and microorganisms on the item 2 that are not sensitive to high temperatures. In this way, the disinfection equipment can use two different disinfection principles to disinfect the item 2.
