Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to an air sterilization module for enclosed spaces. Background Technology

[0002] As people's demands for the quality of their living and working environments continue to rise, air sterilization in enclosed spaces is becoming increasingly important. In various enclosed places such as hospitals, laboratories, cleanrooms, and offices, airborne microorganisms such as bacteria, viruses, and fungi can cause disease transmission, product contamination, and other problems, seriously threatening people's health and the normal operation of production activities.

[0003] Currently, common enclosed space air sterilization devices, such as the air purification and sterilization module with patent publication number CN220309485U, can effectively concentrate overflowing ultraviolet rays onto the entire application scenario, eliminating bacteria without blind spots, reducing ultraviolet waste, and increasing ultraviolet irradiation intensity to achieve more effective sterilization and purification. While these devices can sterilize the air to a certain extent, they still have many shortcomings.

[0004] First, existing sterilization modules are large and have low space utilization; the UV lamp panel and circuit board are too compact, which leads to poor heat dissipation. Second, they have low modularity and low installation and disassembly efficiency. On the other hand, they cannot achieve efficient sterilization. Finally, there is a lack of real-time monitoring methods, which makes it impossible to detect UV lamp malfunctions in a timely manner. Utility Model Content

It solves the problems of existing sterilization modules, such as large size, low space utilization, poor heat dissipation due to overly compact UV lamp board and circuit board, low modularity, low installation and disassembly efficiency, inability to achieve high-efficiency sterilization, lack of real-time monitoring means, and inability to detect UV lamp malfunctions in a timely manner.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An enclosed space air sterilization module includes a sterilization chamber, a fan housing, a UV lamp panel, and a driver board. The sterilization chamber is a through-hole cavity with baffles at both ends. An air outlet, a lamp hole, and an air inlet are also provided on the side of the sterilization chamber. The outer side of the sterilization chamber is fixedly connected to the fan housing and a driver board mounting base. The driver board is mounted on the driver board mounting base. The UV lamp panel is fixedly mounted on the side of the sterilization chamber, allowing the UV lamps on the UV lamp panel to irradiate the sterilization chamber through the lamp hole.

The ultraviolet radiometer is connected and controlled on the drive board, and the drive board receives the data detected by the ultraviolet radiometer, thereby monitoring the radiation dose in real time.

[0011] Preferably, the sterilization chamber is further provided with multiple adsorption plates, each adsorption plate being parallel to the UV light illumination direction on the UV lamp plate. One edge of each adsorption plate has a gap with the inner wall of the sterilization chamber to allow for gas flow. The gaps on adjacent adsorption plates are positioned symmetrically.

[0039] Example 1:

[0040] This embodiment provides an air sterilization module for enclosed spaces, which has the following technical features.

[0041] Please see Figure 1-8 A closed-space air sterilization module includes a sterilization chamber 1, a fan housing 2, a UV lamp panel 6, and a drive plate 8. The sterilization chamber 1 is a cavity that runs through the middle, with cavity baffles 5 at both ends. The side of the sterilization chamber 1 is also provided with an air outlet 11, a lamp hole 12, and an air inlet 13. The outside of the sterilization chamber 1 is fixedly connected to the fan housing 2 and the drive plate mounting base 7. The drive plate 8 is mounted on the drive plate mounting base 7. The UV lamp panel 6 is fixedly mounted on the side of the sterilization chamber 1, so that the UV lamp on the UV lamp panel 6 passes through the lamp hole 12 and irradiates into the sterilization chamber 1. A fan 3 is provided inside the fan housing 2, and an air intake 21 is provided on the fan housing 2. The air inlet and outlet of the fan 3 are connected to the air intake 21 and the air inlet 13, respectively. The side of the drive plate mounting base 7 away from the drive plate 8 is attached to the fan housing 2. The drive plate 8 provides current to the UV lamp panel 6 and the fan 3 through electrical connection. The drive plate 8 is also provided with a detection component for detecting the working status of the UV lamp panel 6.

[0042] It should be noted that the cavity baffle 5 is fixedly connected to the sterilization cavity 1 by bolts.

[0043] Furthermore, the detection component on the driver board 8 is a current sensor, which is used to detect changes in the input current of the UV lamp board 6, thereby determining whether the UV lamp board 6 has malfunctioned.

[0044] It should be noted that the detection component on the drive board 8 can also be an ultraviolet radiometer installed inside the sterilization chamber 1, used to detect the radiation dose per unit area inside the sterilization chamber 1. The ultraviolet radiometer is connected to the drive board 8, and the drive board 8 receives the data detected by the ultraviolet radiometer, thereby monitoring the radiation dose in real time.

[0045] Furthermore, the sterilization chamber 1 is equipped with multiple adsorption plates 51. Each adsorption plate 51 is parallel to the UV light illumination direction on the UV lamp plate 6. One edge of each adsorption plate 51 has a gap with the inner wall of the sterilization chamber 1 to allow for gas flow. The gaps on adjacent adsorption plates 51 are positioned symmetrically. The adsorption plates 51 are activated carbon plates used to adsorb solid and liquid particles in the air, thereby sterilizing and disinfecting bacteria attached to the particles for a longer period of time. At the same time, the gaps do not affect the airflow speed. The adsorption plates 51 are connected and fixed to the chamber baffle 5 by connecting plates 52, which are parallel to the UV light illumination direction on the UV lamp plate 6.

[0046] It should be noted that the connecting plate 52 is designed with a hollow structure to reduce weight, and the surface of the connecting plate 52 is coated with a reflective coating.

[0047] Furthermore, a sealing gasket 71 is provided at the connection between the drive board mounting base 7 and the fan housing 2, and a sealing ring 22 is provided at the connection between the fan housing 2 and the air inlet 13.

[0048] Furthermore, the inner surface of the sterilization chamber 1 is provided with a reflective coating.

[0049] It should be noted that reflective coatings mainly include reflective films, reflective fabrics, and reflective paints. Reflective films are functional composite materials created by embedding high-refractive-index glass microspheres or microprisms into the surface of a material using coating, lamination, and composite technologies to achieve light reflection and form a reflective phenomenon. Reflective fabrics are materials with reflective properties and are often used to make various warning signs, safety reflective clothing, etc. Reflective paints include reflective varnishes, which are formulated by mixing acrylic resin as a base with a certain proportion of directional reflective materials in a solvent. They are a new type of reflective paint. For example, ultraviolet reflective pigments such as titanium dioxide and zinc oxide reflect light back into the viewer's line of sight through reflective microspheres, forming a reflective effect. The reflective effect is more obvious at night.

[0050] Furthermore, the sterilization chamber 1 is detachably fixed to the outer shell 9 by bolts, the drive plate mounting base 7 is detachably fixed to the side of the sterilization chamber 1 by bolts, the UV lamp plate 6 is detachably fixed to the side of the sterilization chamber 1 by bolts, the drive plate 8 is detachably fixed to the drive plate mounting base 7 by bolts, and a panel 4 is also provided on the outer shell 9 to cover the internal structure of the outer shell 9.

[0051] Furthermore, a reflective coating is provided on the side of the cavity baffle 5 near the inside of the sterilization cavity 1.

[0052] Furthermore, the driver box 7 has a power socket on its side, and the driver board mounting base 7 has a power socket on its side for mounting the power port of the driver board mounting base 7.

[0053] Furthermore, a pressure plate 61 is provided at the connection between the fan housing 2 and the housing 9.

[0054] Furthermore, the sterilization chamber 1 is made of metal, which has good heat dissipation performance.

[0055] In summary, this enclosed space air sterilization module, by setting UV lamp plate 6, drive plate 8 and fan housing 2 on the outside of sterilization chamber 1, and setting UV lamp plate 6 and drive plate 8 on two sides of sterilization chamber 1 respectively, and rationally arranging fan housing 2, fan 3 and drive plate mounting base 7 on housing 9, can not only improve the space utilization of the module, but also prevent the UV lamp plate 6 from affecting the drive plate 8 when it heats up. The modular installation of each component improves assembly efficiency.

[0056] The enclosed space air sterilization module has lamp holes 12 on the sterilization chamber 1, which are used not only to irradiate the UV lamps on the UV lamp panel 6 into the sterilization chamber 1, but also to use airflow to directly cool the UV lamp panel 6.

[0057] The enclosed space air sterilization module's drive board 8 not only provides current to the UV lamp board 6 and fan 3, but also monitors the input current of the UV lamp board 6 in real time, thereby determining whether the UV lamp board 6 has malfunctioned.

[0058] This enclosed space air sterilization module, by setting an adsorption plate 51 inside the sterilization chamber 1 and connecting plate 52 parallel to the UV light to avoid blocking the ultraviolet light, and leaving a gap between the adsorption plate 51 and the sterilization chamber 1, ensures that the adsorption plate 51 provides adsorption while maintaining air circulation speed, so as to carry out more intense sterilization of bacteria adsorbed on liquid or solid particles and improve the sterilization rate.

[0059] This enclosed space air sterilization module improves the heat dissipation efficiency of the drive board 8 by attaching the drive board 8 and the drive board mounting base 7 to the fan housing 2.
