Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment, and more particularly to the field of disinfection boxes, specifically referring to an ultraviolet circulating drying and disinfection box device. Background Technology

[0002] Existing drying and sterilization equipment suffers from inefficiencies in its hot air circulation design. High airflow resistance leads to uneven heat distribution, affecting drying performance and increasing energy consumption. Traditional structures lack optimized airflow layout and guidance design, resulting in turbulent hot air flow and hindering efficient circulation. Furthermore, the commonly used PTC heating elements suffer from low heating efficiency and poor temperature uniformity, easily causing localized overheating during prolonged operation, increasing energy consumption and posing safety hazards.

[0003] Furthermore, the safety protection mechanisms of existing equipment are relatively weak. Most lack integrated overheat protection or abnormal temperature alarm functions, making it unable to respond quickly in case of malfunctions and posing a risk of equipment overheating damage or even fire. Although some equipment has ultraviolet sterilization functions, they are not effectively coordinated with the drying module. This may lead to the ultraviolet lamps becoming overheated and attenuated or the drying efficiency decreasing due to simultaneous operation, affecting overall performance.

[0004] To address the aforementioned shortcomings, there is an urgent need for a solution that can optimize the hot air circulation structure, improve heating efficiency and safety, and achieve intelligent time-sharing control of sterilization and drying, so as to meet the needs of efficient, energy-saving and safe drying and disinfection. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultraviolet circulating drying and disinfection box device that meets the requirements of high efficiency, safety, convenience and wide applicability.

[0006] To achieve the above objectives, the ultraviolet circulating drying and disinfection box device of this utility model is as follows:

[0007] The main features of this ultraviolet circulating drying and disinfection chamber device are as follows: the device includes a chamber body and a door; the chamber body is divided into three layers: a first layer, a middle layer, and a third layer; the middle layer is the drying layer; the device also includes ceramic heating elements, ultraviolet lamps, and a timer switch; the ceramic heating elements are installed on both sides of the middle layer of the chamber body; the ultraviolet lamps are installed on both sides of the first and third layers of the chamber body; a fan vent is provided on the top of the chamber body; a ventilation fan is installed above the fan vent; and the timer switch is installed at the rear of the chamber body, and the timer switch is connected to both the ceramic heating elements and the ultraviolet lamps.

[0008] Preferably, the device further includes a switch lock and a copper connecting block. The switch lock is mounted on the housing, and the copper connecting block is mounted on the back of the housing door. The positions of the switch lock and the copper connecting block correspond, and the copper connecting block supports insertion into the switch lock.

[0009] Preferably, the switch lock includes a positive electrode spring and a negative electrode spring, the positive electrode spring and the negative electrode spring are located on the upper side and the lower side of the switch lock, and the copper connecting block is inserted between the positive electrode spring and the negative electrode spring.

[0010] Preferably, the device further includes an insulating block, which is installed between the copper connecting block and the door.

[0011] Preferably, the device further includes an overheat protection alarm and a temperature sensor. The temperature sensor is installed on the rear side of the second layer, and the overheat protection alarm is installed on the door. The overheat protection alarm includes an alarm light and a buzzer, and the temperature sensor is connected to the alarm light and the buzzer.

[0012] Preferably, the device further includes a grid plate, which is mounted on the bottom surface of the first layer and the intermediate layer.

[0013] This novel ultraviolet (UV) circulating drying and disinfection box utilizes a timer switch for intelligent time-sharing control of both UV sterilization and ceramic heating element drying functions. The independent operation of these two functions avoids the problems of UV lamp attenuation or hot air interference caused by simultaneous operation in traditional equipment. Users can also flexibly adjust the working time according to the characteristics of the items, balancing functional adaptability and energy saving. In the hot air circulation device, the ceramic heating elements, combined with a top ventilation fan and optimized airflow layout, form a directional circulating airflow. The layered design of the central drying zone and the heating elements on both sides significantly reduces heat accumulation. For safety, the door lock-linked power switch, through the precise cooperation of copper connecting blocks and spring contacts, ensures that power is only applied when the door is fully closed, completely eliminating the risk of UV leakage and electric shock. The ceramic heating elements themselves have a stable upper temperature limit, combined with insulation block isolation and overheat protection mechanisms, automatically reducing power or shutting down in case of abnormal temperature, far exceeding the safety of traditional solutions. Furthermore, the modular structure design allows for independent installation and easy maintenance of components such as UV lamps and heating elements. The three-layer partitioned space can classify and process items of different sizes, offering broad application value. Attached Figure Description

[0032] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.

[0033] This utility model discloses an ultraviolet circulating drying and disinfection box device, which includes a box body and a box door. The box body is divided into three layers: a first layer, a middle layer, and a third layer. The middle layer is a drying layer. The device also includes a ceramic heating element, an ultraviolet lamp, and a timer switch. The ceramic heating element is installed on both sides of the box body of the middle layer. The ultraviolet lamp is installed on both sides of the box body of the first and third layers. A fan vent is provided on the top of the box body, and a ventilation fan is installed above the fan vent. The timer switch is installed at the rear of the box body and is connected to both the ceramic heating element and the ultraviolet lamp.

[0034] In a preferred embodiment of this utility model, the device further includes a switch lock and a copper connecting block. The switch lock is installed on the housing, and the copper connecting block is installed on the back of the housing door. The positions of the switch lock and the copper connecting block are corresponding, and the copper connecting block supports insertion into the switch lock.

[0035] In a preferred embodiment of the present invention, the switch lock includes a positive electrode spring and a negative electrode spring, which are located on the upper and lower sides of the switch lock, respectively, and the copper connecting block is inserted between the positive electrode spring and the negative electrode spring.

[0036] In a preferred embodiment of this utility model, the device further includes an insulating block, which is installed between the copper connecting block and the box door.

[0037] In a preferred embodiment of this utility model, the device further includes an overheat protection alarm and a temperature sensor. The temperature sensor is installed on the rear side of the second layer of the enclosure, and the overheat protection alarm is installed on the door of the enclosure. The overheat protection alarm includes an alarm light and a buzzer, and the temperature sensor is connected to the alarm light and the buzzer.

[0038] In a preferred embodiment of the present invention, the device further includes a grid plate, which is installed on the bottom surface of the first layer and the intermediate layer.

[0039] In this specific embodiment of the invention, the ultraviolet circulating drying and disinfection box is divided into three compartments. The middle compartment is for drying, while ceramic heating elements are added to both sides to increase the internal temperature. The top and bottom compartments each contain ultraviolet lamps for sterilization. A fan vent is located at the top for ventilation. The ultraviolet lamps and ceramic heating elements operate independently. A timer switch is installed at the back of the disinfection box to control their respective fixed operating times. This allows for a 10-minute ultraviolet sterilization followed by a 10-minute drying process using the ceramic heating elements. The sterilization and heating times can also be set on the timer switch as needed. The ceramic heating elements provide stable heating with a relatively low upper heating limit, making them ideal for use in drying boxes.

[0040] A switch lock is designed on the door. The circular protrusion on the door is a copper connecting block, and the corresponding latch on the box is the main power switch lock. There are positive and negative springs on both sides. The circuit can only be connected when the door is closed, that is, when the copper connecting block is inserted between the two springs. An insulating block is designed on the copper connecting block as a support platform to play the role of insulation protection.

[0041] This invention integrates drying and sterilization. The spring switch on the door serves as the main power switch, preventing accidental activation. The drying and sterilization time can be set according to the situation.
