Description

Technical Field

[0001] This utility model relates to the field of sterilization cabinet technology for mother and baby, specifically a novel sterilization cabinet for mother and baby with directional airflow circulation. Background Technology

[0002] A baby sterilizer is a household appliance designed specifically for baby products. It uses various sterilization methods such as high temperature, ozone, ultraviolet light or high temperature steam to deeply sterilize and dry baby products such as bottles, nipples, bottle caps, bottle brushes, ampoules, and tableware, ensuring a sterile environment, reducing the risk of bacteria and pathogens, and helping parents to more conveniently maintain the hygiene and safety of baby products. Currently, most baby sterilizers on the market use a combination of ultraviolet (UV) sterilization and PTC heating drying technology. The internal air circulation system is crucial for drying efficiency and sterilization effectiveness. Common sterilizers often have their air inlets and outlets located on the same side or in overly concentrated positions, leading to chaotic airflow organization within the cabinet. This can easily cause airflow short-circuiting (i.e., air is discharged directly without passing over all items) or create circulation dead zones. Specifically, this manifests as: uneven drying: items near the air inlets and outlets dry quickly, while items far from the inlets and outlets, especially those at the bottom and corners of the cabinet, remain damp for extended periods, resulting in prolonged drying time, low efficiency, and incomplete sterilization: a damp environment weakens the UV sterilization effect, and items in airflow dead zones may pose a risk of bacterial growth due to insufficient drying. Energy waste: to thoroughly dry all items, the drying time must be extended, increasing unnecessary energy consumption. To address these problems, the inventors have proposed a novel directional airflow circulation baby sterilizer to solve these issues. Utility Model Content

[0003] In order to solve the problems of uneven airflow circulation, dead drying corners, and low efficiency in existing baby sterilizers, the purpose of this utility model is to provide a new type of baby sterilizer with directional airflow circulation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel directional airflow circulation baby sterilizer, comprising a cabinet body, wherein a sterilization module is installed inside the cabinet body, the sterilization module comprising a first ultraviolet UV lamp bead, a second ultraviolet UV lamp bead, a third ultraviolet UV lamp bead, and a fourth ultraviolet UV lamp bead; an air duct system is provided at the rear of the cabinet body, the air duct system comprising a built-in fan and a PTC heater; a first air inlet is installed in the middle of the right side of the inner back wall of the cabinet body, a second air inlet is installed in the lower right side of the inner back wall of the cabinet body, an upper shelf, a middle shelf, and a lower shelf are installed inside the cabinet body, and a set of vertical strip-shaped air outlets is provided in the upper left side of the inner back wall of the cabinet body.

[0005] Preferably, the first air inlet is located in the middle of the upper shelf and the middle shelf, and the first air inlet adopts a left-right wall insertion hole design.

[0006] Preferably, the second air inlet is located in the lower part of the space between the middle shelf and the lower shelf. The second air inlet has a structure of two rows of horizontal strips and adopts a downward insertion hole design. The air outlet has a structure of vertical strips and adopts a design of inserting a hole towards the center.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a layout with dual air inlets on the lower right side and air outlets on the upper left side, along with a directional design of the wall insertion holes, to actively guide airflow and form a dry circulation system that is efficient, three-dimensional, and has no dead angles. This significantly shortens the drying time, ensures uniform drying from the top to the bottom, avoids damp dead angles, and improves the consistency and reliability of the entire cabinet. 2. In this utility model, by achieving more uniform airflow coverage on the basis of uniform drying, the ultraviolet disinfection effect is improved; at the same time, the drying time is shorter and the energy consumption is lower when achieving the same drying effect, which reflects higher energy utilization efficiency and environmental friendliness.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-3 As shown, this utility model provides a novel directional airflow circulating sterilizer for mothers and babies, including a cabinet body 1. A cabinet door is installed on the outside of the cabinet body 1 to seal it. A sterilization module is installed inside the cabinet body 1. The sterilization module includes a first ultraviolet (UV) lamp 2, a second ultraviolet (UV) lamp 9, a third ultraviolet (UV) lamp 10, and a fourth ultraviolet (UV) lamp 11. The UV lamps continuously release ultraviolet light in a dry and temperature-controlled environment, rapidly inactivating surface bacteria and pathogens, thus improving the sterilization effect. By setting the first ultraviolet (UV) lamp 2, the second ultraviolet (UV) lamp 9, the third ultraviolet (UV) lamp 10, and the fourth ultraviolet (UV) lamp 11... 1. It can disinfect maternal and infant products in all directions. The rear of the cabinet 1 is equipped with an air duct system, which includes a built-in fan and a PTC heater. The fan is used to transmit air force, and the PTC heats the air transmitted by the fan into dry hot air. The first air inlet 3 is installed in the middle of the right side of the inner back wall of the cabinet 1, and the second air inlet 4 is installed in the lower right side of the back wall of the cabinet 1. Hot air enters the cabinet 1 through the second air inlet 4. The cabinet 1 is equipped with an upper shelf 6, a middle shelf 7, and a lower shelf 8. The upper shelf 6, the middle shelf 7, and the lower shelf 8 are used to place items to be disinfected. The upper left side of the inner back wall of the cabinet 1 is equipped with a set of vertical strip-shaped air outlets 5. The air outlets 5 are used to discharge the gas circulated in the cabinet 1.

[0015] The first air inlet 3 is located in the middle of the upper shelf 6 and the middle shelf 7. The first air inlet 3 adopts a left-right wall insertion hole design, that is, the ventilation hole is in the horizontal left-right direction with the axis direction outward, so that the incoming hot air can be horizontally swirled and blown towards the middle position of the cabinet 1.

[0016] By adopting the above technical solution, hot air is blown horizontally towards the items placed in the middle of cabinet 1 (such as baby bottle bodies, nipple caps, bowls, etc.). This horizontal jet can penetrate the gaps between the items, ensuring that all surfaces of the middle layer items are enveloped by hot air, achieving uniform drying.

[0017] The second air inlet 4 is located in the lower part of the space between the middle shelf 7 and the lower shelf 8. The structure of the second air inlet 4 is two rows of horizontal bars, and it adopts a downward insertion design, that is, in the lower part of the space between the middle shelf 7 and the lower shelf 8, so that the incoming hot air can be blown directly to the bottom of the cabinet 1.

[0018] By adopting the above technical solution, the second air inlet 4 adopts the "horizontal bar downward insertion hole" design, so that the incoming hot air blows directly to the bottom of the cabinet 1. This airflow can effectively impact and stir the bottom layer of the cabinet, the area most prone to accumulating humid and cold air, and carry the moisture at the bottom to participate in the main circulation. This completely solves the problem of ineffective drying of bottom items in traditional designs, as well as the problem of insufficient hot air entering the bottle when it is upside down.

[0019] The air outlet 5 has a vertical strip structure and adopts a design with wall holes inserted towards the center. That is, the ventilation holes are horizontally oriented inward along the axis, so as to more effectively draw in the humid and hot air in the core area of ​​the cabinet.

[0020] By adopting the above technical solution, the air outlet 5 can efficiently capture and exhaust the hot and humid air carrying a large amount of water vapor rising inside the cabinet 1. Since hot air naturally flows upward, placing the air outlet 5 at the top conforms to thermodynamic principles, resulting in the highest exhaust efficiency. At the same time, the "center-direction" design prevents the airflow from being directly sucked away against the wall, ensuring sufficient circulation.

[0021] Working principle: During operation, items to be disinfected are placed on the upper shelf 6, middle shelf 7, and lower shelf 8 inside cabinet 1. Then, the fan is activated, causing outside air to be heated into dry hot air by a PTC heater. This hot air then enters the disinfection chamber from the first air inlet 3 and the second air inlet 4 at different directions and angles. Figure 2 As shown by the middle arrow, the two incoming air streams rotate vertically in the lower layer and swirl horizontally in the middle layer of cabinet 1, mixing and diffusing to form a three-dimensional circulating airflow from right to left and from bottom to top. This airflow fully flows over the surfaces of all items and the inner cavities of bottles, cans, and lids, carrying moisture and turning into humid, hot air, which is finally discharged from the upper left side through the air outlet 5. This cycle repeats until the items are completely dried.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
