Description

Technical Field

[0001] This utility model relates to the field of pipeline sterilization and disinfection technology, specifically to an ultraviolet disinfection machine for HVAC systems. Background Technology

[0002] In modern buildings, air conditioning systems have become indispensable facilities; however, they also bring potential health hazards. Air conditioning units, especially central air conditioning systems, provide convenient conditions for the growth and spread of bacteria and germs due to their complex interconnected structures. In a central air conditioning system, once an area is contaminated by pathogens, these pathogens can easily enter the fresh air mixing room through the return air system and then rapidly spread to various areas of the building through the supply air system.

[0003] Typically, ultraviolet (UV) lamps are installed inside HVAC ducts to disinfect the air in the return air section, reducing the need for fresh air supply, lowering energy consumption, and improving the system's economic efficiency. However, practical applications face several challenges. For example, UV disinfection lamps have a limited lifespan, requiring timely replacement when they reach the end of their lifespan or become damaged. Current technology necessitates removing the entire device from the HVAC ducts before replacing the UV lamp and then reinstalling the entire device back into the ductwork. Utility Model Content

[0050] Reference Figures 1-11 This utility model proposes an ultraviolet disinfection machine for HVAC, including a main body 100, which is installed on HVAC pipes or a wall. The main body 100 has a first end 110 and a second end 120. The first end 110 is located outside the HVAC pipe, and the second end 120 is located inside the HVAC pipe. The main body 100 has a first through hole 130 for connecting the first end 110 and the second end 120. A connector 200 is detachably installed at the first through hole 130. After the connector 200 is installed on the first through hole 130, its two ends are located at the two ends of the first through hole 130. An ultraviolet disinfection lamp 300 is installed on the connector 200. After the connector 200 is installed on the first through hole 130, the ultraviolet disinfection lamp 300 is located inside the HVAC pipe. The first through hole 130 is used for the ultraviolet disinfection lamp 300 to enter or leave the interior of the HVAC pipe.

[0051] In this embodiment, the ultraviolet disinfection lamp tube 300 can be easily replaced without disassembling the entire device through the detachable connector 200. This not only saves operation time and labor costs, but also avoids the damage that frequent disassembly and assembly of the entire device may cause to the HVAC pipes or walls, ensuring the stability and sealing of the system, and further preventing gas leakage from the main body 100 in the HVAC pipes.

[0052] When the UV disinfection lamp 300 needs to be replaced, the connector 200 is removed from the first through hole 130, allowing the UV disinfection lamp 300 to be removed from the HVAC duct through the first through hole 130. When installing a new UV disinfection lamp 300, the connector 200 with the new lamp is installed on the first through hole 130, placing the UV disinfection lamp 300 inside the HVAC duct. The connector 200 is snapped into the main body 100 through the first through hole 130, further facilitating the removal and removal of the connector 200.

[0053] Furthermore, the ultraviolet disinfection lamp 300 and the connector 200 are detachably connected. After the ultraviolet disinfection lamp 300 is installed on the connector 200, the ultraviolet disinfection lamp 300 and the connector 200 are electrically connected.

[0054] In this embodiment, after the connector 200 is removed from the first through hole 130, the operator removes the ultraviolet disinfection lamp tube 300 through the connector 200. Then, the ultraviolet disinfection lamp tube 300 that needs to be replaced is removed from the connector 200, and a new ultraviolet disinfection lamp tube 300 is installed on the connector 200. The connector 200 and the ultraviolet disinfection lamp tube 300 can be connected by a socket and a plug, which is not only convenient to connect, but also avoids the disadvantage of wire connections being prone to tangling.

[0055] Furthermore, the sidewall of the first through hole 130 has a first slot 131, which has a first segment 1311 and a second segment 1312 connected in sequence. The length direction of the first segment 1311 is parallel to the axis of the first through hole 130, and the length direction of the second segment 1312 is perpendicular to the length direction of the first through hole 130. It also includes a locking block 210, which is disposed on the outer wall of the connector 200. After the locking block 210 enters the first segment 1311, the locking block 210 rotates into the second segment 1312. After the locking block 210 enters the second segment 1312, the connector 200 is axially engaged with the first through hole 130.

[0056] In this embodiment, a locking block 210 is installed on the outer wall of the connector 200. When installing the connector 200, first align the locking block 210 with the first segment 1311 and insert it, then rotate the connector 200 so that the locking block 210 enters the second segment 1312. After the locking block 210 enters the second segment 1312, the connector 200 is axially locked and fixed in the first through hole 130, and cannot be easily moved axially. Through this cooperation between the slot and the locking block 210, the connector 200 can be quickly installed and stably positioned axially, ensuring that the connector 200 will not accidentally fall off during use. The operator only needs to perform the insertion and rotation actions to complete the installation of the connector 200, improving installation efficiency. The locking block 210 and the slot also enhance the reliability and stability of the connection between the connector 200 and the first through hole 130, reducing the possibility of the connector 200 loosening due to vibration or other external forces.

[0057] Furthermore, it also includes an elastic sheet 1321, one end of which is disposed on the side wall of the first through hole 130. The elastic sheet 1321 has an elastic deformation force along the radial direction of the first through hole 130. An arc-shaped groove 1322 is disposed at the other end of the elastic sheet 1321. A locking post 220 is disposed on the outer wall of the connector 200. The axis of the locking post 220 is parallel to the axis of the first through hole 130. After the locking block 210 enters the second section 1312, the locking post 220 enters the arc-shaped groove 1322. The arc-shaped groove 1322 is used to prevent the locking post 220 from rotating.

[0058] In this embodiment, after the locking block 210 fully enters the second section 1312 and completes the axial locking, the locking post 220 will enter the arc-shaped locking groove 1322. Due to the restriction of the arc-shaped locking groove 1322, the locking post 220 experiences certain resistance when rotating again, thus preventing the connector 200 from rotating during normal use. The elastic plate 1321, the arc-shaped locking groove 1322, and the locking post 220 increase the restriction on the rotation of the connector 200, improve the stability and reliability of the connector 200 after installation, and effectively prevent it from rotating unexpectedly due to vibration or other factors during operation. The locking structure of the elastic plate 1321, the arc-shaped locking groove 1322, and the locking post 220 is not only simple, but also requires only a certain force to cause the elastic plate 1321 to deform elastically when installing and disassembling the connector 200, thereby allowing the locking post 220 to enter or leave the arc-shaped locking groove 1322, further improving the convenience of operation.

[0059] Furthermore, it also includes a metal sheet 133 disposed in the first through hole 130; a metal post 230 is disposed on the connector 200. After the locking block 210 enters the second section 1312, the metal post 230 abuts against the metal sheet 133. After the metal post 230 abuts against the metal sheet 133, the metal post 230 and the metal sheet 133 are electrically connected.

[0060] In this embodiment, when the locking block 210 is fully inserted into the second section 1312, and the connector 200 is axially engaged with the first through hole 130, the metal post 230 will contact the metal sheet 133, and an electrical connection will be established between the connector 200 and the main body 100, providing a stable power supply to the ultraviolet disinfection lamp tube 300. This contact-type electrical connection is automatically achieved after the connector 200 is installed in place, making the operation simple and requiring no additional complex wiring operations.

[0061] Furthermore, it also includes a fastening sleeve 400, which is set at one end of the connector 200 located inside the HVAC duct. The ultraviolet disinfection lamp tube 300 passes through the fastening sleeve 400 and is connected to the connector 200. The fastening sleeve 400 is used to lock the ultraviolet disinfection lamp tube 300.

[0062] In this embodiment, when the ultraviolet disinfection lamp 300 is installed, the ultraviolet disinfection lamp 300 passes through the fastening sleeve 400 and is then connected to the connector 200. The fastening sleeve 400, through its own structural characteristics, such as clamping or threaded connection, locks the ultraviolet disinfection lamp 300 to prevent it from loosening or falling off. The structure of the fastening sleeve 400 is quite common and will not be described in detail here.

[0063] The fastening sleeve 400 enhances the stability of the connection between the ultraviolet disinfection lamp tube 300 and the connector 200, ensuring that the ultraviolet disinfection lamp tube 300 can work stably and without displacement under the complex environmental conditions inside the HVAC duct.

[0064] Furthermore, it also includes an air inlet 510, which is located at the second end 120; a sensor switch is located inside the air inlet 510, and the sensor switch is used to control the opening and closing of the ultraviolet disinfection lamp tube 300.

[0065] In this embodiment, when air flows through the air inlet 510, the sensor switch controls the opening and closing of the ultraviolet disinfection lamp 300 based on the detected airflow. For example, when airflow is detected, the sensor switch controls the ultraviolet disinfection lamp 300 to turn on for disinfection; when airflow stops for a period of time, the sensor switch controls the ultraviolet disinfection lamp 300 to turn off, thus saving energy and extending the lamp's lifespan. The automatic control of the ultraviolet disinfection lamp 300 is achieved through the air inlet 510 and the sensor switch, turning it on and off according to actual ventilation needs, avoiding unnecessary energy waste and improving energy efficiency.

[0066] Furthermore, it also includes a protective cover 600, which is located at the second end 120. The protective cover 600 is located inside the HVAC duct and is used to protect the ultraviolet disinfection lamp tube 300.

[0067] In this embodiment, the protective cover 600 completely or partially covers the outside of the ultraviolet disinfection lamp tube 300, providing physical protection. It prevents external objects from directly colliding with the ultraviolet disinfection lamp tube 300, reducing the risk of damage. Simultaneously, it can also, to a certain extent, block large particulate impurities in the airflow from impacting and contaminating the lamp tube.

[0068] Furthermore, the protective cover 600 has several second through holes 610 for the light from the ultraviolet disinfection lamp tube 300 to pass through.

[0069] In this embodiment, while providing physical protection for the ultraviolet disinfection lamp 300, the effective propagation of the disinfection light is ensured, guaranteeing that the disinfection effect is not affected. The second through-hole 610 not only prevents the protective cover 600 from obstructing the ultraviolet disinfection lamp 300 from irradiating the air inside the HVAC duct, improving the comprehensiveness and uniformity of disinfection, but also helps reduce the resistance of the protective cover 600 to airflow, ensuring the normal operating efficiency of the ventilation system.

[0070] Furthermore, it also includes a liquid crystal display device 700, which is disposed at the first end 110. The liquid crystal display device 700 is used to display the usage time and fault status of the ultraviolet disinfection lamp tube 300.

[0071] In this embodiment, the liquid crystal display device 700 is connected to the control circuit of the ultraviolet disinfection lamp 300, enabling real-time monitoring and recording of the lamp's usage time. Simultaneously, when the ultraviolet disinfection lamp 300 malfunctions, such as lamp damage or circuit abnormalities, the relevant fault information can be detected and displayed on the liquid crystal display screen. The liquid crystal display device 700 allows users to intuitively understand the usage time of the ultraviolet disinfection lamp 300, facilitating timely replacement to ensure disinfection effectiveness. Furthermore, it can quickly and accurately display fault conditions, enabling users to promptly identify and take repair measures, reducing the impact of equipment malfunctions on ventilation and disinfection.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
