DETAILED DESCRIPTION

[0033] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] In the description of the present application, it should be pointed out that the directions or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the indicated devices or elements must have a specific direction, be constructed and operated in a specific direction.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application.

[0036] The embodiments of the present application disclose a sterilizer.

[0037] The following will be described in conjunction with the drawings Figures 1-11To be specific, the disinfecting device comprises a shell 2, a disinfecting cavity for disinfection is formed in the shell 2, a door plate 4 is covered on the opening of the disinfecting cavity, the disinfecting cavity is surrounded by a cavity back plate 9, a cavity bottom plate 11 and two cavity side plates opposite to each other.

[0038] To be specific, the disinfecting device comprises a shell 2, a disinfecting cavity for disinfection is formed in the shell 2, a door plate 4 is covered on the opening of the disinfecting cavity, the disinfecting cavity is surrounded by a cavity back plate 9, a cavity bottom plate 11 and two cavity side plates opposite to each other.

[0039] The cavity back plate 9 has a back side air inlet 95, and the cavity bottom plate 11 has a bottom side air inlet 111.

[0040] Two ventilation channels with independent and respective built-in heating bodies are formed in the shell 2, one end of the ventilation channel of one of the two ventilation channels is communicated with the back side air inlet 95 and the other end is communicated with the first fan 16, and one end of the ventilation channel of the other of the two ventilation channels is communicated with the bottom side air inlet 111 and the other end is communicated with the second fan 20.

[0041] The working principle of the disinfecting device is as follows: when the disinfecting device is started, the ventilation channels with the two built-in heating bodies operate simultaneously. On the one hand, the ventilation channel communicated with the back side air inlet 95 of the cavity back plate 9 forms hot air in the channel while the heating body is working, and then the hot air is forcibly blown into the disinfecting cavity through the side air inlet one under the drive of the first fan 16 to heat and dry the objects placed therein; on the other hand, the ventilation channel communicated with the bottom side air inlet 111 of the cavity bottom plate 11 works in the same principle, the heating body heats the air, and the second fan 20 blows the hot air to the bottom of the disinfecting cavity through the bottom side air inlet 111 to heat the objects from the bottom. In this way, the hot air is supplied in two directions simultaneously to form a full-range hot air circulation.

[0042] It can be seen that the disinfecting device can significantly improve the drying efficiency. Since the two heating bodies are set to work synchronously, the power is greatly increased, compared with the disinfecting device with a single heating body or a single air duct design, the temperature inside the product cavity of the disinfecting device can be rapidly increased in a short time, therefore, the rapid temperature rise means that the time required for drying is greatly shortened, which greatly meets the needs of modern users for high efficiency in fast-paced life. Whether it is a baby bottle 7, a nipple or other daily necessities, the drying process can be quickly completed and the product can be put into use at any time.

[0043] The sterilizer also optimizes drying uniformity. Since two independent air channels are used to deliver hot air to the sterilization cavity from the bottom and the rear respectively, the temperature unevenness caused by a single air channel is effectively avoided, ensuring that all objects in the sterilization cavity can be uniformly heated, and the problem of partial drying of objects is completely solved. The objects after each sterilization and drying can reach the ideal dry state, ensuring the quality of sterilization and drying.

[0044] In summary, since the general sterilizer has only a single heating body and a single air channel structure, the temperature rise in the product cavity is relatively slow due to low power. Since the drying effect is directly related to the temperature, the higher the temperature, the better the drying effect. Therefore, the single heating body and single air channel structure have a relatively long drying time. In the present application, the two heating bodies work simultaneously, and the power is increased, so the temperature rise in the product sterilization cavity is accelerated, greatly improving the overall drying efficiency of the product.

[0045] Specifically, the sterilizer further comprises a fixed rear plate 25, a first air duct cover 17 and a second air duct cover 21 fixed on the fixed rear plate 25, and the two heating bodies are a first heating body 18 and a second heating body 22, respectively. The first heating body 18 is fixed in the first air duct cover 17, and the second heating body 22 is fixed in the second air duct cover 21.

[0046] The fixed rear plate 25 is arranged on the side of the cavity rear plate 9 away from the sterilization cavity and forms a rear air duct cavity 252 with the cavity rear plate 9. The rear air duct cavity 252 is in communication with the rear air inlet 195, the rear air duct inlet 251 of the rear air duct cavity 252 is in communication with the second air duct cover 21, and the second air duct cover 21 is in communication with the second air outlet 201 of the second fan 20. In this way, after the second fan 20 is started, the hot air heated by the second heating body 22 in the second air duct cover 21 is sequentially delivered to the rear side of the sterilization cavity through the rear air duct inlet 251, the rear air duct cavity 252 and the rear air inlet 195, and then flows out. This is one of the air channels.

[0047] The sterilizer also comprises a bottom air duct cover 24, which is fixed on the side of the cavity bottom plate 11 away from the sterilization cavity and forms a bottom air duct cavity 242 with the cavity bottom plate 11. The bottom air duct cavity 242 is in communication with the bottom air inlet 111, the bottom cavity air inlet 241 of the bottom air duct cavity 242 is in communication with the first air duct cover 17, and the first air duct cover 17 is in communication with the first air outlet 161 of the first fan 16. In this way, after the first fan 16 is started, the hot air heated by the first heating body 18 in the first air duct cover 17 is sequentially delivered to the bottom side of the sterilization cavity through the bottom cavity air inlet 241, the bottom air duct cavity 242 and the bottom air inlet 111, and then flows out. This is another air channel.

[0048] After the sterilizer is started, the first fan 16 and the second fan 20 are opened synchronously, and the whole system is rapidly operated.

[0049] For the ventilation channel driven by the second fan 20: the second heating body 22 is fixed in the second air duct cover 21 and rapidly heats after being powered on to heat the surrounding air. At this time, the second fan 20 operates to generate suction, and the external cold air enters and is mixed with the hot air heated by the second heating body 22 to form a hot air flow. Under the push of the second fan 20, the hot air flow flows through the rear air duct inlet 251 in turn, enters the rear air duct cavity 252. The rear air duct cavity 252 acts as a transition space to buffer and uniformize the flow, so that the hot air flow uniformly and stably flows into the sterilization cavity through the rear inlet 95. The hot air flows in the sterilization cavity to transfer heat to the sterilization and drying objects placed therein, realizing the heating and drying process from the rear side.

[0050] At the same time, in the ventilation channel affected by the first fan 16: the first heating body 18 also heats in the first air duct cover 17 to heat the air flowing through it. When the first fan 16 works, it draws external air into the first air duct cover 17, and after the hot air is formed, it is pushed by the strong force of the first fan 16 to enter the bottom air duct cavity 242 through the bottom inlet 241. The bottom air duct cavity 242 preliminarily gathers and arranges the hot air to ensure the stability of the air flow, and then the hot air accurately flows to the bottom of the sterilization cavity through the bottom inlet 111. The hot air blown out from the bottom surges upward and wraps the bottom of the object from all directions, completing the heating and drying task from the bottom.

[0051] In the sterilization cavity, the two-way hot air flows in cooperation and circulation to continuously provide heat to the objects until the set drying temperature and time are reached, completing the entire sterilization and drying process.

[0052] It can be seen that the sterilizer can achieve efficient drying, and the two heating bodies and the two fans work together, which greatly improves the power compared with the traditional single heating structure. The two heating bodies heat at the same time, which can rapidly heat the sterilization cavity in a very short time, greatly shortening the preheating time required for drying, greatly improving the overall drying efficiency, meeting the urgent needs of modern people for rapid processing of baby supplies or other daily sterilization and drying of objects, and allowing users to quickly use the objects again, saving valuable time.

[0053] And, the sterilizer can also be uniformly heated. Due to the unique air duct design, hot air is accurately delivered from the bottom and the rear side, ensuring that there is no temperature dead angle in the sterilization cavity. Regardless of the height, horizontal or vertical placement of the objects at different positions, they can all uniformly contact the hot air, effectively avoiding the phenomenon of partial drying and partial dampness. This is particularly critical for baby products with complex structures and various shapes, such as bottles with curved straws and multi-component combined nipples, ensuring that every detail is completely dried and improving the sterilization and drying quality.

[0054] Specifically, a first air duct cavity 172 can be formed between the first air duct cover 17 and the fixed rear plate 25, the first air duct outlet 171 of the first air duct cavity 172 is in communication with the bottom cavity air inlet 241 of the rear air duct cavity 252, and the opposite air inlets are in communication with the first air outlet 161 of the first air fan 16. In this way, each component cooperates and supports each other, not only saving internal space and making the appearance of the sterilizer more compact, but also enhancing the stability of the overall structure.

[0055] Further, the shell 2 includes a rear cover 12 located at the back, and the rear cover 12 is provided with an air inlet cover 13, and the air inlet cover 13 is provided with a cover air inlet 131 for communication between the inside and outside of the shell 2. In the drying mode, the first air fan 16 and the second air fan 20 are started at the same time. Since the air inlet cover 13 installed on the rear cover 12 of the back of the shell 2 is provided with the cover air inlet 131, which serves as a communication between the inside and outside of the shell 2. The cold air outside enters the inside of the shell 2 under the suction of the fan, and the cold air entering the inside of the shell 2 is sucked into the first air fan 16 and the second air fan 20, and then flows through the two air channels as described above, thereby forming a complete air circulation, continuously introducing, heating and using external cold air for drying, achieving the purpose of drying.

[0056] It can be seen that the air inlet cover 13 and the cover air inlet 131 ensure stable air supply. This organized air intake method ensures that the drying equipment will not be affected by insufficient air intake, which can more effectively utilize external air resources and ensure the continuous and efficient operation of the drying work.

[0057] Further, the cavity rear plate 9 has a rear side air outlet one 91 and a rear side air outlet two 92, the rear cover 12 has a cover air outlet one 121 and a cover air outlet two 122, and the rear side air outlet one 91 and the rear side air outlet two 92 are one-to-one corresponding to the cover air outlet one 121 and the cover air outlet two 122. In this way, the moisture can be discharged in time, and the drying process will be more efficient. For example, when drying baby products, the externally connected air outlets can accelerate the discharge of water vapor, shorten the drying time, and improve the overall drying efficiency.

[0058] Specifically, the power cord 14 of the sterilizer can be introduced into the product through the rear cover 12.

[0059] Another object of the present application is to improve the drying efficiency of the sterilizer. Since the hot air in the sterilization chamber of the sterilizer flows from the lower part to the upper part, the temperature of the upper part is generally lower than that of the lower part, and therefore the drying of the upper part is slower than that of the lower part. To improve the drying efficiency, an additional air duct structure is added to make the temperature of the upper part and the lower part of the sterilization chamber more uniform.

[0060] Specifically, the sterilizer further comprises a third fan 28, a third air duct cover 27 and a fourth air duct cover 29, which are all fixed to the fixed rear plate 25. The third air duct cover 27 and the fixed rear plate 25 form a third air duct cavity 271 therebetween, and the fourth air duct cover 29 and the fixed rear plate 25 form a fourth air duct cavity 291 therebetween.

[0061] The rear plate 9 of the cavity has a rear inlet three 93 and a rear inlet four 94 arranged in a top-bottom manner. The rear inlet three 93, the third air duct cavity 271, the third fan 28, the fourth air duct cavity 291 and the rear inlet four 94 are sequentially connected.

[0062] Therefore, when the third fan 28 is working, the hot air in the upper part of the sterilization chamber enters the third air duct cavity 271 through the rear inlet three 93 of the upper part of the rear plate 9 of the cavity, is blown into the fourth air duct cavity 291 by the third fan 28, and finally returns to the sterilization chamber from the rear inlet four 94 of the lower part of the rear plate 9 of the cavity, so as to form a hot air circulation. Through such circulation, the air flow in the upper and lower parts of the sterilization chamber of the product is accelerated, and the temperature deviation of the air in the upper and lower parts of the sterilization chamber is reduced, thereby further improving the overall drying efficiency of the product.

[0063] Specifically, the sterilizer further comprises an upper shelf 6 and a lower shelf 8 arranged in the sterilization chamber. The facing surfaces of the two cavity side plates are both provided with aligned support steps for supporting the upper shelf 6 and the lower shelf 8. For example, during specific operation, baby products such as bottle caps 5 can be placed on the upper shelf 6, and cleaned feeding bottles 7 can be placed on the lower shelf 8.

[0064] In this way, firstly, a stable and reliable support structure is provided for the upper shelf 6 and the lower shelf 8, ensuring that the shelves can be stably placed during the sterilization process, even if the device is subjected to certain vibration or shaking, so as to avoid the falling and collision of the sterilized objects placed on the shelves due to the displacement of the shelves, thereby preventing damage. Secondly, the precisely aligned support steps make the installation and removal of the upper shelf 6 and the lower shelf 8 extremely convenient, and users can easily complete the installation and removal of the shelves without complex operations or the aid of additional tools, thereby greatly improving the use convenience and saving time and effort.

[0065] Specifically, the support steps are provided in plurality, specifically including a first support step 112, a second support step 113 and a third support step 114, and the first support step 112, the second support step 113 and the third support step 114 of the two cavity side plates are respectively and correspondingly arranged in alignment.

[0066] Further specifically, the lower shelf 8 has a plurality of pairs of vertical positioning ribs 81, and the cavity bottom plate 11 has a plurality of bottom side air inlets 111, and each pair of positioning ribs 81 of the lower shelf 8 is arranged in alignment with one bottom side air inlet 111 of the cavity bottom plate 11. In this way, when the lower shelf 8 is installed on the support steps, the positioning ribs 81 correspond to the bottom side air inlets 111 one by one, and when the baby bottle 7 is placed upside down on the lower shelf 8, the positioning ribs 81 are inserted into the bottle opening 71 of the baby bottle 7 as positioning, so that the bottle opening 71 of the baby bottle 7 is aligned with the bottom side air inlet 111 of the cavity bottom plate 11. Therefore, in actual use, hot air can directly enter the inside of the baby bottle 7 without any obstruction, forming an efficient air circulation channel, accelerating the evaporation of water in the bottle, and compared with the design without positioning, the drying time required for the baby bottle 7 is significantly shortened, so that the baby bottle 7 can be quickly restored to a dry and clean state, meeting the needs of parents who use the baby bottle 7 frequently. In this regard, since the bottom side air inlet 111 is opposite to the bottle opening 71 of the baby bottle 7 during work, the drying of the inner surface of the baby bottle 7 can be realized, solving the problem of difficult drying of the inner surface of the baby bottle 7.

[0067] Further specifically, the sterilizer also includes a plurality of ultraviolet lamps 10, and the plurality of ultraviolet lamps 10 are distributed on the cavity back plate 9 and the cavity bottom plate 11. In this way, the multi-directional layout can realize multi-angle irradiation, and whether the sterilized objects placed on the upper shelf 6 and the lower shelf 8 in the sterilization cavity can be fully covered by ultraviolet light, greatly improving the thoroughness of sterilization and effectively killing bacteria, viruses and microorganisms hidden in various corners and different surfaces, thereby providing all-round health protection for users.

[0068] Further specifically, the sterilizer also includes a first temperature controller 19, a second temperature controller 23 and a power board 15, and the power board 15 is electrically connected with the first temperature controller 19 and the second temperature controller 23; the first temperature controller 19 is assembled in the first air duct cover 17, and the second temperature controller 23 is assembled in the second air duct cover 21. The first temperature controller 19 and the second temperature controller 23 can be specifically self-resetting temperature controllers, and when the hot air passes through the first temperature controller 19 and the second temperature controller 23, the temperature of the heated hot air is too high, and the power supply of the first heating body 18 and the second heating body 22 is controlled to be cut off by the power board 15 to prevent the temperature in the sterilization cavity from being too high.

[0069] Further, the sterilizer also comprises a temperature sensor 26, which is electrically connected to the power board 15 and located in the sterilization cavity.

[0070] Further, the sterilizer also comprises a control panel 3 and a door handle 1, which are arranged on the outer side of the door panel 4. In this way, the control panel 3 is arranged on the outer side of the door panel 4, greatly improving the operation convenience. Users can easily control the functions of the sterilizer, such as selecting the sterilization mode and setting the sterilization time, without opening the cabinet door, which not only saves operation time but also avoids the sterilization environment from being destroyed due to frequent opening of the door, ensuring the efficiency and stability of the sterilization process. Moreover, the door handle 1 is arranged on the outer side of the door panel 4, which is easy to grasp, allowing users to quickly and accurately open the cabinet door when needed.

[0071] The technical means disclosed in the utility model scheme is not limited to the technical means disclosed in the above-mentioned embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that, for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, which are also considered within the protection scope of the utility model.
