Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning parts technology, specifically to an easily detachable ultraviolet germicidal lamp. Background Technology

[0002] As a key device for regulating the temperature and air circulation inside a vehicle, the automotive air conditioning system is prone to the growth of bacteria, mold, viruses, and other microorganisms in its air intake passages, blower housing, and evaporator surfaces due to suitable temperature and humidity during long-term use. To address the problem of microbial contamination in automotive air conditioning systems, the industry typically installs ultraviolet germicidal lamps at the air intake of the blower housing or at the air intake housing location to disinfect the air.

[0003] However, most existing automotive air conditioning UV germicidal lamps adopt a fixed structure, requiring tools for installation and disassembly, making maintenance and replacement inconvenient. At the same time, the germicidal lamp and the housing are mostly positioned using a single slot, which is prone to misinstallation due to inaccurate positioning during assembly. Furthermore, the single slot positioning has poor fit with the housing, resulting in insufficient stability of the UV germicidal lamp.

[0004] To address these issues, an easily detachable ultraviolet germicidal lamp is provided. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-disassemble ultraviolet germicidal lamp, which solves the problems of inconvenient disassembly and assembly, easy positioning errors, and poor structural stability of existing automotive air conditioning ultraviolet germicidal lamps.

[0006] This utility model achieves the above objectives through the following technical solutions: A detachable ultraviolet germicidal lamp includes a frame and a communication connector detachably connected to the frame. The frame is provided with multiple ultraviolet lamp beads, and the mounting surface of the frame is provided with a positioning slot structure for forming a double engagement and fixation with the blower housing and the air inlet housing. The positioning slot structure includes a first limiting slot and a second limiting slot.

[0007] As a further optimization of this utility model, the frame is formed by three straight plates and one arc-shaped plate; the outer wall of the arc-shaped plate is fixedly provided with a positioning post and a communication post, the positioning post is used to apply force to assist in the disassembly of the frame, and the communication post is used to achieve a plug-in connection with the communication connector.

[0008] As a further optimization of this utility model, two first limiting slots are provided, which are respectively formed between the root of the positioning column and the outer wall of the arc-shaped plate and between the root of the communication column and the outer wall of the arc-shaped plate. The two first limiting slots are used to form a matching engagement with the protruding structure at the corresponding position of the air inlet housing.

[0009] As a further optimization of this utility model, there are two second limiting slots, which are respectively formed on the side walls of two oppositely arranged straight plates facing the blower housing. The two second limiting slots are used to form a matching engagement with the protruding structure at the corresponding position of the blower housing.

[0010] As a further optimization of this utility model, six ultraviolet lamp beads are provided, symmetrically arranged on two oppositely arranged straight plates. One ultraviolet lamp bead is embedded on the inner side of each straight plate, and two ultraviolet lamp beads are embedded on the outer side. The ultraviolet lamp beads on the inner side are located on the vertical line between the two ultraviolet lamp beads on the outer side. The straight plate is provided with a mounting groove for installing the ultraviolet lamp beads, and the cross section of the mounting groove is trapezoidal.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model provides a composite positioning slot structure consisting of a first limiting slot and a second limiting slot on the frame, which works in conjunction with the corresponding protrusions on the blower housing and the air inlet housing to achieve quick assembly and disassembly and precise error-proof positioning, reducing the difficulty of maintenance operations. This double-slot structure is more stable and can better adapt to the vibration environment during vehicle operation because it is fixed to both the blower housing and the air inlet housing at the same time.

[0012] 2. This utility model optimizes the layout and installation structure of the ultraviolet lamp beads to achieve double-sided irradiation, covering a wider airflow cross section, ensuring that the sterilization range covers the air conditioning intake channel, eliminating disinfection blind spots, and improving sterilization efficiency.

Detailed Implementation

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1 To address the issues of inconvenient disassembly and assembly, proneness to positioning errors, and poor structural stability of existing automotive air conditioning UV germicidal lamps, please refer to... Figures 1-4 , Figure 6 This utility model provides an easily detachable ultraviolet germicidal lamp, including a frame 1 and a communication connector 2 detachably connected to the frame 1. Multiple ultraviolet lamp beads 101 are arranged on the frame 1. A positioning slot structure is provided on the mounting surface of the frame 1 for double-locking fixation with the blower housing 3 and the air inlet housing 4. The positioning slot structure includes a first limiting slot 107 and a second limiting slot 108. Through the cooperation of the positioning slot structure and the protruding structures on the blower housing 3 and the air inlet housing 4, rapid positioning during assembly and disassembly is achieved, thereby enabling rapid assembly and disassembly of the germicidal lamp, reducing maintenance difficulty. Furthermore, it can be simultaneously fixed to the blower housing 3 and the air inlet housing 4, resulting in higher structural stability and better adaptability to the vibration environment during vehicle operation.

[0017] The frame 1 is formed by three straight plates 103 and one arc-shaped plate 104. The outer side wall of the arc-shaped plate 104 is fixedly provided with a positioning post 105 and a communication post 106. The positioning post 105 is used to apply force to assist in the disassembly of the frame 1, and the communication post 106 is used to achieve a plug-in connection with the communication connector 2.

[0018] Two second limiting slots 108 are provided, respectively formed on the side walls of two oppositely arranged straight plates 103 facing the blower housing 3. The two second limiting slots 108 are used to form a matching engagement with the protruding structure at the corresponding position of the blower housing 3.

[0019] To achieve the above-mentioned snap-fit ​​connection, such as Figure 4 As shown, a convex ring 301 is coaxially fixed to the air inlet of the blower housing 3. The convex ring 301 engages with the second limiting groove 108 to achieve positioning and fixing of the frame 1 and the blower housing 3.

[0020] Two first limiting slots 107 are provided, respectively formed between the root of the positioning post 105 and the outer wall of the arc-shaped plate 104 and between the root of the communication post 106 and the outer wall of the arc-shaped plate 104. The two first limiting slots 107 are used to form an adaptive engagement with the protruding structure at the corresponding position of the air inlet housing 4.

[0021] To achieve the above-mentioned snap-fit ​​connection, such as Figures 4-5 As shown, the air inlet housing 4 is fixed with two symmetrically distributed longitudinal ribs 401, an arc-shaped rib 403 for connecting the ends of the two longitudinal ribs 401, and two transverse ribs 402 that connect the middle of each longitudinal rib 401 to the inner wall of the air inlet housing 4. The longitudinal ribs 401, arc-shaped ribs 403 and transverse ribs 402 are all integrally formed with the air inlet housing 4. The longitudinal ribs 401 and transverse ribs 402 are arranged perpendicularly and staggered, and the bottom of both are engaged with the protruding ring 301 to fix the air inlet housing 4 to the blower housing 3. The arc-shaped rib 403 is engaged with the first limiting groove 107 to fix the frame 1 to the air inlet housing 4. When the air inlet housing 4 is installed onto the blower housing 3, the longitudinal rib 401 and the transverse rib 402 are aligned with the convex ring 301 at the air inlet of the blower housing 3, so that the grooves at the bottom of the longitudinal rib 401 and the transverse rib 402 are engaged in the convex ring 301, thereby fixing the air inlet housing 4 coaxially at the air inlet of the blower housing 3, forming a stable mounting base for installing the ultraviolet germicidal lamp.

[0022] Furthermore, wedge-shaped protrusions 404 are integrally formed on both the longitudinal ribs 401 and the transverse ribs 402. The wedge-shaped protrusions 404 are surrounded to form a positioning cavity that matches the shape of the frame 1, which is used to accommodate the frame 1. The straight plate 103 is provided with a wedge-shaped surface that matches the wedge-shaped protrusions 404, so as to achieve precise positioning of the frame 1.

[0023] During installation, the ultraviolet germicidal lamp is placed at the air intake of the car's air conditioning system, specifically above the blower, where air flows past or just enters the blower. The three straight plates 103 of the frame 1 are aligned with the positioning cavity enclosed by the longitudinal ribs 401 and transverse ribs 402 inside the air intake housing 4. Through the guiding engagement of the wedge-shaped surfaces of the straight plates 103 and the wedge-shaped protrusions 404, the entire frame 1 is inserted into the positioning cavity. Simultaneously, the second limiting groove 108 on the straight plates 103 engages with the blower... The convex ring 301 of the fan housing 3 is engaged, and the first limiting groove 107 of the arc plate 104 is engaged with the arc rib 403 of the air inlet housing 4. When a click is heard, it indicates that the positioning groove structure and the protruding structure are fully engaged, and the frame 1 is installed in place. The communication connector 2 is inserted into the communication post 106 to realize the conduction between the ultraviolet lamp 101 and the car circuit. When disassembling, hold the positioning post 105 and apply outward pulling force. The positioning anti-misalignment groove structure separates from the protruding structure, and the frame 1 comes out of the positioning cavity of the air inlet housing 4, completing the disassembly.

[0024] Example 2 Based on Example 1, in order to improve the sterilization coverage and sterilization effect, such as Figure 1 As shown, six ultraviolet (UV) lamps 101 are symmetrically arranged on two oppositely positioned straight plates 103. One UV lamp 101 is embedded on the inner side of each straight plate 103, and two UV lamps 101 are embedded on the outer side. The UV lamps 101 on the inner side are located on the perpendicular line between the two UV lamps 101 on the outer side. Each straight plate 103 has a mounting groove 102 for installing the UV lamps 101, and the cross-section of the mounting groove 102 is trapezoidal. By optimizing the layout and installation structure of the UV lamps 101, double-sided irradiation is achieved, covering a wider airflow cross-section, ensuring that the sterilization range covers the air conditioning intake channel, eliminating blind spots in disinfection, and improving sterilization efficiency.

[0025] During sterilization, when the car air conditioner is turned on, the communication connector 2 receives the circuit signal and triggers the ultraviolet lamp 101 to start. The six ultraviolet lamps 101 work according to the preset layout. The lamps on the inner side of the two opposing straight plates 103 directly irradiate the central area of ​​the air intake channel, while the ultraviolet lamps 101 on the outer side radiate ultraviolet light to the inner wall and corner areas of the channel, forming a sterilization range without dead angles. When the outside air or the recirculated air in the car enters through the air intake housing 4, it passes through the ultraviolet radiation area, and the bacteria, mold and other microorganisms in the air are destroyed, achieving sterilization and disinfection. The disinfected air is delivered to the car through the blower of the blower housing 3, completing the air purification.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
