Description

Technical Field

[0001] This invention relates to the field of sterilization and disinfection equipment technology, specifically to a sterilization machine and its control method. Background Technology

[0002] As people pay increasing attention to healthy eating, cutting boards, chopsticks, spoons, knives, and other items that come into direct contact with food are very prone to harboring dirt and grime, and even breeding bacteria, mold, parasites, etc. If these bacteria come into contact with food, they may cause potential health problems.

[0003] Therefore, existing technology has developed a sterilization and disinfection device that can sterilize and disinfect cutting boards, chopsticks, spoons, knives, etc. This sterilization and disinfection device usually uses the principles of hot air drying and ultraviolet sterilization to sterilize and disinfect cutting boards, chopsticks, spoons, knives, etc.

[0004] However, the ultraviolet lamps in existing sterilization and disinfection equipment have limited irradiation range and generally poor sterilization and disinfection effects, which cannot meet the ever-increasing needs of users. Summary of the Invention

[0005] In view of this, the present invention provides a sterilization machine and control method to solve the problems of limited irradiation range, mediocre sterilization and disinfection effect, and inability to meet user needs in existing sterilization and disinfection equipment.

[0006] In a first aspect, the present invention provides a sterilization machine, comprising:

[0007] case;

[0008] At least two sterilization zones are provided on the housing;

[0009] At least one of the germicidal lamps is provided in each of the sterilization zones;

[0010] At least one set of germicidal lamp adjustment mechanism is provided on the housing to expand the irradiation range of the germicidal lamp.

[0011] Beneficial effects: The sterilization machine of the present invention, by setting a sterilization lamp adjustment mechanism, can expand the irradiation range of the sterilization lamp in the sterilization zone, increase the irradiation range of the sterilization lamp, improve the coverage area of ​​the sterilization light, thereby improving the sterilization and disinfection effect, meeting the user's needs, and enhancing the user experience.

[0012] In one optional embodiment, the sterilization lamp adjustment mechanism includes a first transmission cover, which is rotatably mounted on the sterilization lamp, and the exit surface of the first transmission cover is an irradiation angle adjustment surface.

[0013] Beneficial effects: In the sterilization machine of the present invention, the first transmission cover is rotatably mounted on the sterilization lamp. The emitting surface of the first transmission cover is an irradiation angle adjustment surface. After the light from the sterilization lamp passes through the irradiation angle adjustment surface, the angle of the emitted light will change, including increasing or decreasing the irradiation angle. When the sterilization light increases the irradiation angle after passing through the irradiation angle adjustment surface, the irradiation range increases. Since the first transmission cover is rotatable, the irradiation range can be further increased. When the sterilization light decreases the irradiation angle after passing through the irradiation angle adjustment surface, the irradiation intensity of the sterilization light can be enhanced. Furthermore, since the first transmission cover is rotatable, it can compensate for the previous reduction in the irradiation angle and increase the irradiation range of the sterilization light, thereby achieving the effect of both expanding the irradiation area and enhancing the irradiation intensity, resulting in a better sterilization effect.

[0014] In one alternative embodiment, the rotation angle of the first transmission cover is (0°, 360°).

[0015] Beneficial effects: The sterilization machine of the present invention has a first transmission cover with a rotation angle of (0°, 360°), which can increase the irradiation range of the sterilization light in all directions and improve the coverage area of ​​the sterilization light, thereby improving the sterilization and disinfection effect.

[0016] In one optional embodiment, the illumination angle adjustment surface is an inclined plane or an inclined convex surface, wherein the vertical bisector L1 of the inclined plane or the principal optical axis of the inclined convex surface forms an angle with the axis L2 of the first transmissive cover.

[0017] Beneficial effects: When the irradiation angle adjustment surface of the present invention is an inclined plane, the sterilization light beam can increase the irradiation angle and irradiation range after passing through the inclined plane. Moreover, since the first transmission cover can rotate, the irradiation range of the sterilization light beam can be further increased, enhancing the sterilization effect. When the irradiation angle adjustment surface is an inclined convex surface, the irradiation angle of the sterilization light beam will decrease after passing through the inclined plane, increasing the irradiation intensity and improving the sterilization effect. Since the first transmission cover can rotate, it can compensate for the previous reduction in irradiation angle and increase the irradiation range of the sterilization light beam. Therefore, when the irradiation angle adjustment surface is an inclined convex surface, it can both expand the irradiation area of ​​the sterilization light beam and enhance the irradiation intensity of the sterilization light beam, resulting in a better sterilization effect.

[0018] In one optional embodiment, the sterilization lamp adjustment mechanism further includes a driving component, which is disposed on the housing, and the output shaft of the driving component drives the first transmission cover to rotate.

[0019] Beneficial effects: The sterilization machine of the present invention includes a sterilization lamp adjustment mechanism that also includes a driving component. The output shaft of the driving component drives the first transmission cover to rotate. This driving method is simple in structure, easy to implement, and convenient to control.

[0020] In one alternative embodiment, the outer edge of the first transmission cover has a gear structure, and a drive gear is provided on the output shaft of the drive member, the drive gear meshing with the gear structure.

[0021] Beneficial effects: The sterilization machine of the present invention is driven by the gear structure of the first transmission cover meshing with the drive gear, which is simple, stable and reliable.

[0022] In one alternative embodiment, the drive gear is a rubber gear or a POM gear.

[0023] Beneficial effects: The sterilization machine of the present invention uses a rubber gear or a POM gear as the drive gear. The surface hardness of rubber or POM material is low, and the gear of this material is relatively soft. During the transmission process, it will not damage the first transmission cover, thus protecting the first transmission cover, and at the same time, it can also achieve the purpose of driving the first transmission cover to rotate.

[0024] In one alternative embodiment, the first transmission cover is disposed on the housing, and a rotation seal is provided at the connection between the first transmission cover and the housing.

[0025] Beneficial effects: The sterilizer of the present invention, by setting a rotating seal, can seal the gap between the housing and the first transmission cover, prevent humid air from entering the sterilizer lamp and affecting the life of the sterilizer lamp, and does not affect the rotation of the first transmission cover.

[0026] In one alternative implementation, each of the sterilization zones is independent of the others.

[0027] Beneficial effects: The sterilization machine of the present invention has independent sterilization zones, which can be sterilized and disinfected separately without affecting each other. This reduces the situation where items to be sterilized block the sterilization light, and ensures the sterilization and disinfection effect on various items.

[0028] In one optional embodiment, the system includes two sterilization zones, namely a first sterilization zone and a second sterilization zone, with two sterilization lamps installed in each of the first and second sterilization zones.

[0029] Beneficial effects: The sterilization machine of the present invention has a first sterilization zone specifically for sterilizing and disinfecting cutting boards, and a second sterilization zone specifically for sterilizing and disinfecting knives, chopsticks, and spoons. Sterilizing the cutting board and knives, chopsticks, and spoons separately prevents the cutting board from being too large and blocking the sterilization light, thus affecting the sterilization effect of the sterilization light on the knives, chopsticks, and spoons. The above-mentioned structural layout is reasonable, which can improve the utilization rate of the sterilization light and significantly improve the sterilization effect.

[0030] In an alternative embodiment, the germicidal lamp in the first germicidal area is located at the top of the first germicidal area, and the germicidal lamp in the second germicidal area is disposed on the side wall of the second germicidal area.

[0031] Advantageous effects: For the germicidal machine of the present invention, due to the relatively large size of the cutting board, the germicidal lamp in the first germicidal area is arranged at the top of the first germicidal area, which can minimize the blockage of the germicidal light by the cutting board, enabling the irradiation area of the germicidal light to cover the entire cutting board, achieving disinfection of all parts of the cutting board, and improving the germicidal rate.

[0032] In an alternative embodiment, a germicidal lamp adjustment mechanism is provided on one of the germicidal lamps in the second germicidal area, and the irradiation ranges of the two germicidal lamps in the second germicidal area partially overlap.

[0033] Advantageous effects: For the germicidal machine of the present invention, for some items to be germicidalized that require local enhanced disinfection, a germicidal lamp adjustment mechanism can be provided on the germicidal lamp near the position that needs to be strengthened, increasing the coverage area of the germicidal light and improving the germicidal effect. Moreover, since the irradiation ranges of the two germicidal lamps partially overlap, after a germicidal lamp adjustment mechanism is provided on one germicidal lamp, the overlapping area will increase, and the irradiation intensity in the overlapping area is stronger, thereby disinfecting the position that needs local enhanced disinfection of the item to be germicidalized, with good germicidal effect and meeting diverse usage requirements.

[0034] In an alternative embodiment, the second germicidal area includes a first cavity and a second cavity. The germicidal lamp in the second germicidal area is disposed in the first cavity or the second cavity, and the first cavity and the second cavity are connected through a through hole.

[0035] Advantageous effects: For the germicidal machine of the present invention, in the second germicidal area, the germicidal lamp is only disposed in the first cavity or the second cavity, and the germicidal light emitted by the germicidal lamp can enter the other cavity through the through hole. Therefore, there is no need to arrange germicidal lamps in both cavities of the second germicidal area, saving product costs while ensuring the germicidal effect.

[0036] Second, the present invention also provides a control method applied to the above-mentioned germicidal machine, including:

[0037] Start the germicidal machine;

[0038] Intermittently turn on the germicidal lamps in different germicidal areas, with the single - time turn - on time of each germicidal lamp being at least a, where 0 < a ≤ 10 min, and / or intermittently turn on the germicidal lamps in the same germicidal area, with the single - time turn - on time of each germicidal lamp being at least a, where 0 < a ≤ 10 min.

[0039] Beneficial Effects: The control method of the present invention, when applied to the aforementioned sterilizer, has the same effect as the sterilizer. Furthermore, by employing an intermittent on / off operating mode for the sterilizer lamps, precise control of the lamp's luminous power and start-up time is achieved. This reduces the maximum power of the sterilizer lamp chip, allowing it to control a larger number of lamps. It also extends the lifespan of the sterilizer lamps, prolongs the lamp's intensity decay time, improves the sterilization rate, ensures sterilization effectiveness, and reduces operating costs.

[0040] In one optional implementation, the total on-time of the sterilization lamps in each sterilization zone is at least 15 minutes.

[0041] Beneficial effects: The control method of the present invention, by limiting the total on-time of each germicidal lamp, can ensure the germicidal effect of each germicidal lamp and ensure the germicidal rate.

[0042] In one optional embodiment, the sterilization lamps located in different sterilization zones are turned on alternately and intermittently. When at least two sterilization lamps are provided in the same sterilization zone, the sterilization lamps located in the same sterilization zone are turned on alternately and intermittently.

[0043] Beneficial effects: The control method of the present invention, by alternating the intermittent opening of sterilization lamps located in different sterilization zones and the intermittent opening of sterilization lamps located in the same sterilization zone, makes the opening time of each sterilization lamp alternate. Each sterilization lamp is not continuously open, but intermittently open, which can not only ensure the sterilization effect, but also protect the service life of the sterilization lamps, and facilitate start-up control, simplifying the control difficulty.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] In the market, the sterilization lamps (usually ultraviolet lamps) of sterilization machines are fixed in setting. Their irradiation range is fixed, and the irradiation intensity cannot be changed. The coverage area of ​​the sterilization zone by the sterilization light (usually ultraviolet light) is limited, so the sterilization effect is generally average and cannot meet the increasingly high usage demands. In addition, during sterilization and disinfection, the ultraviolet lamps are continuously turned on until the sterilization program ends. The long working time of each ultraviolet lamp causes the intensity of the ultraviolet lamp to decay rapidly, affecting its lifespan and impacting the long-term stable sterilization of the sterilization machine, which also increases the user's operating costs.

[0074] Moreover, the sterilization zone of the sterilizer can sterilize and disinfect multiple items at the same time, such as cutting boards, chopsticks, spoons, and knives. However, ultraviolet light is invisible and can only travel in a straight line with weak penetration. Items such as cutting boards can easily block ultraviolet light, which will greatly reduce the area irradiated by ultraviolet light, resulting in low utilization of ultraviolet light. This can lead to situations where the intensity of irradiation is extremely high in some areas, while other areas are blocked, thus affecting the sterilization and disinfection effect.

[0075] The following is combined Figures 1 to 7 This describes an embodiment of the sterilization machine of the present invention.

[0076] According to an embodiment of the present invention, a sterilizer is provided, comprising: a housing 1, at least two sterilization zones, a sterilization lamp 2, and at least one set of sterilization lamp adjustment mechanisms, wherein the sterilization zones are disposed on the housing 1; each sterilization zone is provided with at least one sterilization lamp 2; and the sterilization lamp adjustment mechanisms are disposed on the housing 1 for expanding the irradiation range of the sterilization lamp 2.

[0077] This sterilization machine, by incorporating a sterilization lamp adjustment mechanism, can expand the irradiation range of the sterilization lamps within the sterilization zone, thereby increasing the coverage area of ​​the sterilization light and improving the sterilization and disinfection effect. This meets user needs and enhances the user experience.

[0078] Among them, the shell 1 is the load-bearing structure of the sterilizer and has a certain structural strength. The shell 1 can be used to install and set the relevant structural components, electrical components, interactive panels, etc. of the sterilizer. The structural shape of the shell 1 can be set according to actual usage requirements. The shell 1 is usually made of a lightweight material with sufficient structural strength, so as not to increase the weight of the product too much, and to provide support for other structures of the sterilizer.

[0079] The sterilization zone is used to hold items to be sterilized, where they can be sterilized and disinfected. The layout and number of sterilization zones on the housing 1 can be configured according to actual needs. For example, the number of sterilization zones can be set according to the type of items to be sterilized. The internal structure of the sterilization zone should be adapted to the shape and size of the items to be sterilized, so that the items can be placed stably in the sterilization zone for subsequent sterilization and disinfection.

[0080] The germicidal lamp 2 emits germicidal light to disinfect items it irradiates. In this embodiment, the germicidal lamp 2 is an ultraviolet lamp (UV lamp) that emits ultraviolet light. The germicidal lamp 2 is placed in the sterilization zone to sterilize and disinfect items. The location and number of germicidal lamps 2 in the sterilization zone can be set according to actual usage requirements.

[0081] Of course, the sterilizer in this embodiment also has other related structures and components that are present in existing sterilizers, such as hot air drying mechanism, etc. Since this embodiment does not involve these structures and components, they will not be described in detail.

[0082] Furthermore, to reduce the possibility of items blocking the sterilization light, each sterilization zone is independent of the others.

[0083] The sterilizer in this embodiment includes two sterilization zones: a first sterilization zone 101 and a second sterilization zone 102. These zones are separated and independent of each other. The first sterilization zone is specifically for sterilizing cutting boards, while the second sterilization zone is specifically for sterilizing knives, chopsticks, and spoons. This separate sterilization of cutting boards and knives, chopsticks, and spoons prevents the cutting board from being too large and blocking the sterilization light, thus affecting the sterilization effect. This rational layout of the sterilization zones improves the utilization rate of ultraviolet light and significantly enhances the sterilization effect.

[0084] In other embodiments, three or four sterilization zones may be provided as needed.

[0085] like Figures 1 to 3 As shown, the first sterilization zone 101 has an opening on at least one side, facilitating the user to place the cutting board 6 into and remove it from the first sterilization zone 101. The size and shape of the first sterilization zone 101 are matched to the cutting board 6. In this embodiment, the first sterilization zone 101 has an opening on one side for placing and removing the cutting board.

[0086] In other embodiments, openings may be provided on both sides of the first sterilization zone 101 to facilitate the placement and removal of the cutting board and to facilitate the cleaning of the first sterilization zone.

[0087] The second sterilization zone 102 is located to one side of the first sterilization zone 101, and is further divided into a first cavity and a second cavity. The first cavity is used for sterilizing chopsticks and spoons, and the second cavity is used for sterilizing knives. The interiors of the first cavity and the second cavity are interconnected to facilitate the passage of ultraviolet light for sterilization. Specifically, the first cavity and the second cavity are connected by a through hole, and in the direction of gravity, the height of the first cavity is higher than the height of the second cavity.

[0088] When the user faces the second sterilization zone 102, the second cavity is located to the right of the first cavity, facilitating the insertion and removal of knives and conforming to the hand habits of most users. The second cavity has multiple knife slots to accommodate multiple knives 10. The housing 1 has a door panel 103 in the first cavity, allowing the user to place chopsticks and spoons when the door panel 103 is open. A chopstick basket 7 is located on the inner side of the door panel 103, and a hook for placing spoons 9 is also provided in the first cavity. Furthermore, to facilitate the passage of ultraviolet light, the chopstick basket 7 has a grid, allowing ultraviolet light to pass through the grid and enter the chopstick basket 7 to sterilize the chopsticks inside.

[0089] Two sterilization lamps 2 are installed in each of the first sterilization zone 101 and the second sterilization zone 102. Compared with one sterilization lamp, two sterilization lamps 2 have a larger irradiation area and can improve the sterilization effect.

[0090] Furthermore, the sterilization lamp 2 in the first sterilization zone 101 is located at the top of the first sterilization zone 101, and the sterilization lamp 2 in the second sterilization zone 102 is disposed on the side wall of the second sterilization zone 102.

[0091] In the first sterilization zone 101, the sterilization lamp 2 is set at the top of the first sterilization zone 101. Under no circumstances will the ultraviolet lamp be directly blocked and unable to effectively sterilize due to the different placement of the cutting board. At the same time, the distance between the ultraviolet lamp and the cutting board 6 is increased within the effective range. Through the diffusion angle of the ultraviolet lamp itself, the ultraviolet light can irradiate a larger cutting board area, thereby improving the sterilization efficiency.

[0092] The sterilization lamp 2 in the second sterilization zone 102 is set on the side wall of the second sterilization zone 102. Specifically, the sterilization lamp 2 is set on the side wall of the first cavity away from the second cavity. When the door panel 103 is closed, because the chopstick basket 7 has a grid, ultraviolet light can pass through the chopstick basket 7 to sterilize and disinfect the chopsticks and the spoon 9. The first cavity and the second cavity are connected by a through hole, and ultraviolet light can also enter the second cavity through the through hole to sterilize and disinfect the knife 10. There is no need to set a sterilization lamp in the second cavity, which saves equipment costs while ensuring the sterilization effect.

[0093] In other embodiments, the sterilization lamp 2 of the second sterilization zone 102 may also be installed in the second cavity, and ultraviolet light can be injected into the first cavity through the through hole for sterilization and disinfection.

[0094] Furthermore, the irradiation areas of the two sterilization lamps 2 overlap. Within each sterilization zone, the intensity of the sterilization light in the overlapping area of ​​the two sterilization lamps 2 is superimposed and stronger, which can enhance the sterilization effect.

[0095] like Figures 4 to 5 As shown, in this embodiment, the ultraviolet lamp is mounted on the ultraviolet lamp plate 8, and the ultraviolet lamp plate 8 is provided with multiple ventilation holes 801 for effectively cooling the lamp beads, making their operation more stable and efficient.

[0096] In this embodiment, each sterilization zone is equipped with two ultraviolet lamps, that is, each sterilization zone is equipped with an ultraviolet lamp panel 8, on which two ultraviolet lamps are arranged side by side with a certain distance between them.

[0097] Furthermore, one of the sterilization lamps 2 in the second sterilization zone 102 is equipped with a sterilization lamp adjustment mechanism, and the irradiation ranges of the two sterilization lamps 2 in the second sterilization zone 102 partially overlap.

[0098] In other words, in the second sterilization zone 102, one of the sterilization lamps 2 is equipped with a sterilization lamp adjustment mechanism and is named sterilization lamp A, while the other sterilization lamp 2 is not equipped with a sterilization lamp adjustment mechanism and is named sterilization lamp B. In the first sterilization zone 101, neither of the two sterilization lamps 2 is equipped with a sterilization lamp adjustment mechanism. This is because in the second sterilization zone 102, the sterilization lamp 2 is located on the side wall of the first cavity away from the second cavity. The sterilization light needs to shine upwards to the top of the spoon and spatula, downwards to the bottom of the spoon and spatula, and forwards to the chopsticks in the chopstick basket 7 and the knife 10 in the second cavity. The required illumination range is relatively large, and food residue is easily left on the knives, chopsticks, and spoons, making these areas requiring enhanced sterilization.

[0099] Furthermore, the germicidal lamp 2 (germinal lamp B) without a germicidal lamp adjustment mechanism needs to be protected by a second transmission cover 11. The second transmission cover 11 is connected to the housing 1. In order to prevent humid air from entering the second transmission cover 11 from the sterilization area and affecting the service life of the germicidal lamp, a sealing ring should be set at the connection between the second transmission cover 11 and the housing 1. The sealing ring is made of rubber, which has a good sealing effect and can effectively block humid air and water vapor.

[0100] The exit surface (facing the sterilization area) of the second transmission cover 11 is a plane. Ultraviolet rays will not be refracted after passing through this plane. The second transmission cover 11 is made of quartz glass. This type of transmission cover can make ultraviolet rays have the best penetration, which can greatly reduce the loss of ultraviolet light intensity and thus improve the sterilization effect.

[0101] Furthermore, the sterilization lamp adjustment mechanism includes a first transmission cover 3, which is rotatably mounted on the sterilization lamp 2, and the exit surface of the first transmission cover 3 is the irradiation angle adjustment surface 301.

[0102] In this embodiment, a first transmission cover 3 is rotatably mounted on a sterilization lamp 2 (sterilization lamp A) in the second sterilization zone 102. The first transmission cover 3 is also made of quartz glass to reduce the loss of ultraviolet light intensity and improve the sterilization effect.

[0103] The exit surface of the first transmission cover 3 is the irradiation angle adjustment surface 301. After the light from the sterilization lamp 2 passes through the irradiation angle adjustment surface, the angle of the emitted light will change (resorption will occur), including increasing or decreasing the irradiation angle. When the sterilization light increases the irradiation angle after passing through the irradiation angle adjustment surface, the irradiation range increases. Since the first transmission cover can rotate, the irradiation range can be further increased. When the sterilization light decreases the irradiation angle after passing through the irradiation angle adjustment surface, the irradiation intensity of the sterilization light can be enhanced. Since the first transmission cover 3 can rotate, it can compensate for the previous reduction in the irradiation angle and increase the irradiation range of the sterilization light, thereby achieving the effect of both expanding the irradiation area and enhancing the irradiation intensity.

[0104] In this embodiment, the exit surface of the first transmission cover 3, i.e., the irradiation angle adjustment surface 301, is an inclined plane, and the vertical bisector L1 of this inclined plane forms an angle α with the axis L2 of the first transmission cover 3, such as... Figure 5-6 As shown, the included angle α is an acute angle. The ultraviolet light emitted through this inclined plane is perpendicular to the inclined plane and diffuses at an angle (resisting), which increases the irradiation angle and irradiation range.

[0105] It should be noted that when the first transmission cover 3 rotates, the inclined plane also rotates, and the direction of refraction of ultraviolet rays through the inclined plane also rotates. That is, the ultraviolet rays emitted by this germicidal lamp A are moving and dynamic, which can enhance the ultraviolet intensity of the irradiated area and expand the irradiated area.

[0106] Furthermore, the rotation angle of the first transmission cover 3 is (0°, 360°), that is, the first transmission cover 3 can be rotatably covered on the germicidal lamp 2, so that the germicidal lamp 2 can expand the irradiation area in all directions and make the sterilization effect better.

[0107] Furthermore, the sterilization lamp adjustment mechanism also includes a drive component 4, which is mounted on the housing 1. The output shaft of the drive component 4 drives the first transmission cover 3 to rotate. Specifically, the drive component 4 is a micro motor, which is mounted on the housing 1, and the output shaft of the micro motor drives the first transmission cover 3 to rotate.

[0108] Furthermore, the outer edge of the first transmission cover 3 has a gear structure 302, and a drive gear 5 is provided on the output shaft of the drive member 4, which meshes with the gear structure 302. Specifically, during the molding of the first transmission cover 3, the gear structure 302 is formed on the outer edge of the first transmission cover 3, and the drive gear 5 is coaxially provided on the output shaft of the micro motor, meshing with the gear structure 302. When the output shaft of the micro motor rotates, the drive gear 5 rotates coaxially, thereby driving the first transmission cover 3 to rotate around the axis L2 of the first transmission cover 3.

[0109] Furthermore, the drive gear 5 is a rubber gear or a POM (Polyoxymethylene) gear. In this embodiment, the drive gear 5 is a rubber gear. Since the first transmission cover 3 is made of quartz glass, its edges and corners are relatively fragile. To prevent damage to the first transmission cover 3 during rotation, the drive gear 5 is made of rubber. This type of rubber gear is relatively soft, which can both drive the first transmission cover 3 to rotate and prevent damage to the first transmission cover 3, thus protecting the first transmission cover 3.

[0110] In other embodiments, the drive gear 5 may also be a gear made of a non-metallic material with low surface hardness, such as POM, to prevent damage to the first transmission cover 3.

[0111] Furthermore, the first transmission cover 3 is disposed on the housing 1, and a rotating seal 12 is provided at the connection between the first transmission cover 3 and the housing 1. Specifically, the rotating seal 12 is made of rubber. The rubber seal has a small compression amount when in contact with the first transmission cover 3, which can achieve a rotating sealing effect.

[0112] like Figures 8 to 9 As shown, the same model of germicidal lamp is used. Figure 8 This refers to the irradiation range of the sterilization lamp in the sterilization machine of the present invention. Figure 9 The irradiation range of the existing sterilization lamps in the sterilization machine.

[0113] exist Figure 8 In the second sterilization zone 102, the irradiation range 13 of sterilization lamp A, which is equipped with a sterilization lamp adjustment mechanism, is significantly larger than and covers the irradiation range 14 of sterilization lamp B, which is not equipped with a sterilization lamp adjustment mechanism. That is, in the second sterilization zone 102, the irradiation range 13 of sterilization lamp A is larger than and covers the irradiation range 14 of sterilization lamp B. The overlapping area of ​​the irradiation of sterilization lamp A and sterilization lamp B is the irradiation range 14 of sterilization lamp B.

[0114] exist Figure 9Among them, the irradiation ranges of the existing germicidal lamp C (13') and the existing germicidal lamp D (14') are the same, and the irradiation overlap area 15 of the existing two germicidal lamps C and D is smaller than the irradiation range of a single germicidal lamp (the irradiation range of the existing germicidal lamp C 13', the irradiation range of the existing germicidal lamp D 14').

[0115] It should be noted that the existing germicidal lamps C and D are equivalent to B without a germicidal lamp adjustment mechanism in this embodiment. That is, the irradiation ranges of the existing germicidal lamps C and D are equivalent to the irradiation ranges of two Bs without a germicidal lamp adjustment mechanism in this embodiment.

[0116] From Figure 8 and Figure 9 the comparison, it can be seen that for the two germicidal lamps A and B in this embodiment, the total irradiation area is significantly larger than the irradiation ranges of the existing germicidal lamps C and D. The irradiation overlap area between the germicidal lamp A and the germicidal lamp B in this embodiment (i.e., the irradiation range of the germicidal lamp B 14) is significantly larger than the irradiation overlap area 15 of the existing two germicidal lamps C and D. That is, the area with a greater irradiation intensity of the germicidal machine in this embodiment (the overlap area, the irradiation range of the germicidal lamp B 14) is significantly larger than the area with a greater irradiation intensity of the existing germicidal machine (the irradiation overlap area 15 of the existing two germicidal lamps C and D).

[0117] This proves that by setting a germicidal lamp adjustment mechanism in this embodiment, the irradiation range of the germicidal lamp can be significantly expanded, the irradiation intensity can be enhanced, and thus the germicidal and disinfection effect can be significantly improved to meet the user's usage requirements.

[0118] This embodiment also provides a control method, which is applied to the germicidal machine in the above embodiment and includes:

[0119] Step S01, start the germicidal machine;

[0120] When the user needs to use the germicidal machine, first place the item to be sterilized in the corresponding sterilization area, and then start the germicidal machine to work by operating the interaction panel on the housing 1.

[0121] Of course, multiple sterilization modes can also be set on the interaction panel of the germicidal machine, and the user can select according to needs.

[0122] Step S02, intermittently turn on the germicidal lamps 2 located in different sterilization areas, and the single - time turn - on time of each germicidal lamp 2 is at least a, where 0 < a ≤ 10 min, and / or intermittently turn on the germicidal lamps 2 located in the same sterilization area, and the single - time turn - on time of each germicidal lamp 2 is at least a, where 0 < a ≤ 10 min.

[0123] After the germicidal machine is started, the germicidal lamps 2 in different sterilization areas are intermittently turned on. In this embodiment, the germicidal lamps 2 in the first sterilization area 101 and the germicidal lamps 2 in the second sterilization area 102 are intermittently turned on. In this embodiment, a = 8 min. Specifically,

[0124] From 0 to 8 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned on, and the sterilization lamp 2 in the second sterilization zone 102 is turned off.

[0125] 9-16 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned off, and the sterilization lamp 2 in the second sterilization zone 102 is turned on;

[0126] 17-23 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned on, and the sterilization lamp 2 in the second sterilization zone 102 is turned off;

[0127] After 24-30 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned off, and the sterilization lamp 2 in the second sterilization zone 102 is turned on.

[0128] During the above process, the sterilization lamps 2 located in different sterilization zones are turned on intermittently. It is understood that the sterilization lamps 2 in different sterilization zones may not be turned on intermittently, but the turning times may overlap, as long as each sterilization lamp 2 is turned on intermittently.

[0129] During the above process, the total running time of the sterilization machine is 30 minutes, and the total on time of the sterilization lamp 2 in each sterilization zone is 15 minutes.

[0130] This intermittent switching control method for germicidal lamps reduces heat accumulation during the operation of a single lamp while ensuring the sterilization effect. It effectively controls the temperature rise of the lamps, reduces power loss due to heat generation, and ensures light intensity. Moreover, this control method can reduce the maximum power of the chip. Under power-limited conditions, the same chip can control more lamps without affecting the sterilization effect.

[0131] Of course, the hot air sterilization function can also be turned on during the sterilization process to assist in sterilization and disinfection through dry hot air.

[0132] In other embodiments, the total on time of the sterilization lamps 2 in each sterilization zone can also be 16 minutes, 20 minutes, etc.

[0133] In other embodiments, step S02 of the above control method may also be: a = 5 min, specifically,

[0134] 0-5 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned on, and the sterilization lamp 2 in the second sterilization zone 102 is turned off;

[0135] After 6-10 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned off, and the sterilization lamp 2 in the second sterilization zone 102 is turned on.

[0136] 11-15 minutes, the sterilization lamp 2 in the first sterilization zone 101 is turned on, and the sterilization lamp 2 in the second sterilization zone 102 is turned off;

[0137] From 16 to 20 minutes, the sterilization lamp 2 in the first sterilization area 101 is turned off, and the sterilization lamp 2 in the second sterilization area 102 is turned on;

[0138] From 21 to 25 minutes, the sterilization lamp 2 in the first sterilization area 101 is turned on, and the sterilization lamp 2 in the second sterilization area 102 is turned off;

[0139] From 26 to 30 minutes, the sterilization lamp 2 in the first sterilization area 101 is turned off, and the sterilization lamp 2 in the second sterilization area 102 is turned on.

[0140] After being turned on, the total running time of the sterilizer is still 30 minutes, and the total on - time of the sterilization lamp 2 in each sterilization area is still 15 minutes.

[0141] Of course, in other embodiments, the total running time of the sterilizer can also be 20 minutes, 40 minutes, etc. According to the total running time, calculate the single - time on - time of the sterilization lamp in each sterilization area, such as a = 6 minutes, 10 minutes, etc. The total on - time of the sterilization lamp 2 in each sterilization area can also be 16 minutes, 18 minutes, etc.

[0142] In other embodiments, step S02 of the control method provided by the present utility model may be:

[0143] Step S02, intermittently turn on the sterilization lamps 2 in the same sterilization area, and the single - time on - time of each sterilization lamp 2 is at least a, where 0 < a ≤ 10 minutes.

[0144] After the sterilizer is started, the sterilization lamps 2 in the same sterilization area are intermittently turned on, regardless of whether the sterilization lamps 2 in other sterilization areas are turned on. In this embodiment, the two sterilization lamps 2 in the first sterilization area 101 are intermittently turned on, and the two sterilization lamps 2 in the second sterilization area 102 are intermittently turned on. As long as it is ensured that each sterilization lamp 2 is intermittently turned on.

[0145] In other embodiments, step S02 of the control method provided by the present utility model may be:

[0146] Step S02, intermittently turn on the sterilization lamps 2 in different sterilization areas, the single - time on - time of each sterilization lamp 2 is at least a, where 0 < a ≤ 10 minutes, and intermittently turn on the sterilization lamps 2 in the same sterilization area, the single - time on - time of each sterilization lamp 2 is at least a, where 0 < a ≤ 10 minutes. [[ID=二十九]]

[0147] That is to say, after the sterilizer is started, all the sterilization lamps 2 are turned on intermittently. On the premise of ensuring the sterilization effect, the service life of the sterilization lamps is protected, and it is also convenient for start - up control and simplifies the control difficulty.

[0148] Of course, in other embodiments, the housing 1 of the sterilizer may also be provided with three or four sterilization zones, and each sterilization zone may be provided with one or three sterilization lamps 2. Moreover, it is possible to provide sterilization lamp adjustment mechanisms on two or more sterilization lamps, that is, two or more sets of sterilization lamp adjustment mechanisms may be provided.

[0149] In other embodiments, the irradiation angle adjustment surface 301 of the first transmission cover 3 can also be a convex surface, with the principal optical axis of the convex surface forming an angle with the axis L2 of the first transmission cover 3. When the sterilization light beam passes through the convex surface and the irradiation angle is reduced, the irradiation intensity of the sterilization light can be enhanced. Furthermore, since the first transmission cover 3 is rotatable, it can compensate for the previous reduction in the irradiation angle and increase the irradiation range of the sterilization light, thereby achieving the effect of both expanding the irradiation area and enhancing the irradiation intensity, resulting in a better sterilization effect.

[0150] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
