Description

Technical Field

[0001] This utility model relates to the field of air purification, specifically to an air purifier with a safe and quick-change structure. Background Technology

[0002] In today's society, public health awareness is increasing at an unprecedented rate, a trend that profoundly impacts the demand for and application of sanitation facilities in various public places. Among these, air purifiers play a crucial role in densely populated public places such as hospitals, schools, and offices, with their usage frequency and popularity showing a continuous upward trend.

[0003] Among the many types of air purifiers, the ultraviolet (UV) lamp air purifier built into air purifiers has attracted much attention. This type of purifier utilizes the special sterilization function of UV lamps to effectively sterilize the inhaled air, thus creating a relatively clean and healthy air environment for people. However, despite its excellent performance in air sterilization, some problems have emerged in actual use that urgently need to be addressed.

[0004] Existing UV air purifiers have certain design limitations. Disassembling their outer casing requires specific specialized tools, and this process is often cumbersome and time-consuming. Only after disassembling the casing can maintenance personnel access the internal functional components and begin repairs. More seriously, during repairs, personnel are highly susceptible to touching the UV lamp tube. The UV lamp tube emits radiation during operation, and this unprofessional contact could expose maintenance personnel to radiation risks, posing a potential threat to their health. Therefore, designing an air purifier with an easily maintainable structure is particularly necessary. Summary of the Invention

[0005] The problem this invention aims to solve is to provide an air purifier with a safe and quick-change structure, which allows for the repair of internal functional parts without disassembling the outer casing, and eliminates the risk of radiation damage to repair personnel during the repair process.

[0006] The technical solution adopted by this utility model to solve the above problems is an air purifier with a safe and quick-change structure, including a front frame. The front frame includes a vertically penetrating mounting groove. A mounting bracket is installed on the back of the front frame at the edge of the mounting groove. Spring latches are provided at both ends of the mounting bracket. A grille is installed in the mounting groove. The grille has vertically protruding hooks at both ends of the horizontal direction. When the hooks are vertically inserted into the spring latches to fix the grille in the mounting groove, the grille closes the mounting groove, and at the same time, the grille is in contact with the limit switch fixed on the mounting bracket.

[0007] Compared to existing technologies, an air purifier with a safe and quick-change structure features a front frame comprising a vertically penetrating mounting slot and a grille plate installed within the slot. A mounting bracket is installed on the back of the front frame at the edge of the mounting slot, with spring latches at both ends of the mounting bracket (these spring latches are push-button switch latches or universal latches commonly used in trash cans and eyeglass cases). The grille plate has vertically protruding hooks at both ends of its horizontal direction. When the hooks are vertically inserted into the spring latches to achieve engagement, the grille plate not only closes the mounting slot but also engages with a limit switch fixed to the mounting bracket. This structural design eliminates the need to disassemble the entire outer casing for internal component repairs, unlike traditional methods. Maintenance personnel can easily inspect the internal components simply by opening the grille plate (through a simple operation connecting the spring latches and hooks), significantly saving time and effort, and eliminating the need for specialized tools. Meanwhile, during maintenance, pressing both ends of the grille plate will separate the spring clips from the hooks, allowing the hollow grille to be disassembled. This enables the repair and replacement of functional parts installed in the mounting slot. Simultaneously, the grille plate is separated from the limit switch button, disconnecting the product circuit and stopping all functions, thus preventing maintenance personnel from being exposed to ultraviolet radiation. Furthermore, the ultraviolet lamp has a simple structure and is easy to install, using a plug-in connection method. No special tools are required for maintenance, reducing the workload of maintenance personnel.

[0008] Preferably, the mounting bracket has clip grooves at both ends of its horizontal direction, and the spring clips are installed in the clip grooves. The detachable structure facilitates the replacement of parts.

[0009] Preferably, the upper end of the grille plate protrudes upward to form a rectangular frame, and multiple grille pieces are arranged longitudinally at intervals at the lower part of the rectangular frame. An airflow channel is formed between two adjacent grille pieces, and a filter block is installed above the airflow channel. The design of installing the filter block above the airflow channel is consistent with the structure of the entire air purifier, further optimizing the air purification process and efficiency.

[0010] Preferably, the longitudinal ends of the rectangular frame protrude upwards to form two opposing pressing plates. The inner side of each pressing plate protrudes inwards to form pressing protrusions. The filter block is inserted between the two pressing plates, with the insertion surface abutting against the pressing protrusions. This design provides a stable and reliable installation method for the filter block. The abutment between the pressing protrusions and the filter block effectively prevents displacement of the filter block due to vibration or other reasons during air purifier operation, ensuring the filter block's fixed position above the airflow channel, thereby ensuring continuous and stable filtration of the air passing through the airflow channel. Simultaneously, this insertion and pressing structure design facilitates the installation and replacement of the filter block. When the filter block needs to be replaced, simply apply appropriate external force to overcome the resistance of the pressing protrusions to remove the old filter block and install the new one. The operation is simple and convenient, which is beneficial for the maintenance and upkeep of the air purifier.

[0011] Preferably, the mounting slot includes an air inlet slot and an air outlet slot that are longitudinally spaced apart on the front frame. An ultraviolet lamp assembly is fixed above the mounting bracket located at the air inlet slot, and a fan is fixed above the mounting bracket located at the air outlet slot. When air enters from the air inlet slot, the ultraviolet lamp assembly can sterilize and disinfect the incoming air, effectively killing harmful microorganisms such as bacteria and viruses that may exist in the air, thereby ensuring the hygiene and safety of the air.

[0012] A fan is fixed above the mounting bracket located in the air outlet slot. The presence of the fan is crucial for the normal operation of the air purifier. It provides power for airflow, enabling the air, after being sterilized by the ultraviolet lamp component, to flow smoothly out through the air outlet slot. This creates a stable airflow path inside the purifier, achieving continuous air purification and circulation, and ensuring the entire air purification process is efficient and stable.

[0013] Preferably, both ends of the mounting bracket extend laterally outward to form fixing parts, the lower end face of the fixing parts is attached to the back of the front frame, and is fixedly connected to the front frame by fasteners. Attached Figure Description
