Description

Technical Field

[0001] This utility model relates to the field of elevator air purification technology, specifically an elevator car air purification and germ disinfection system. Background Technology

[0002] Elevators are indispensable vertical transportation tools in modern buildings. Modern elevators mainly consist of a traction system (steel cables and an electric motor), a car, guide rails, a control system, and safety devices. They achieve efficient operation through pulley systems and counterweight balancing. Common types include passenger elevators, freight elevators, escalators, and hydraulic elevators. In special environments, there are also explosion-proof elevators and machine-room-less elevators.

[0003] Due to the indispensability of elevators and the large volume of people going up and down them, various people are inside the elevators. Some walk their pets, while others smoke, resulting in poor air quality inside the elevators. This is especially true in hospitals where there are stricter epidemic prevention requirements, which place even higher demands on the elevator interior. Usually, air purification mechanisms are installed at the top of the elevator to achieve air exchange and purification through filters and air diversion devices. However, the purification effect of filters is limited and it is difficult to remove bacteria. In addition, the air inlet and outlet are fixed, and the air quality in the elevator car far from the air outlet is poor. Therefore, we propose an elevator car air purification and germ disinfection system. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment provides a technical solution: an elevator car air purification and germ disinfection system, including a housing 1, a purification mechanism 2 and an air supply mechanism 4;

[0025] Housing 1: An internal reciprocating mechanism 3 is provided, comprising a guide seat 33, sliding columns 37, and fixed seats 38. Fixed seats 38 are fixedly connected to the top wall of housing 1, distributed front and rear. Sliding columns 37 are evenly distributed between two fixed seats 38. Guide seats 33 are slidably connected between the sliding columns 37. An air supply duct 44 is slidably connected inside the guide seat 33. The reciprocating mechanism 3 also includes sprockets 32, sliders 34, sliding grooves 35, and a base 36. The base 36 is fixedly connected to the top wall of housing 1. Sprockets 32 are rotatably connected to the front and rear ends of the top wall of the base 36 via rotating shafts. Two sprockets 32 are connected via chain drive. A slider 34 is slidably connected to the lower end of the chain. The guide seat 3... A slide groove 35 is fixedly connected to the middle of the upper surface of the 3. The slider 34 is slidably connected inside the slide groove 35. The reciprocating mechanism 3 also includes a motor 31. The top wall of the base 36 is fixedly connected to the motor 31. The output shaft of the motor 31 is fixedly connected to the rotating shaft of the front sprocket 32. The input end of the motor 31 is electrically connected to the output end of the control switch group 5. The output shaft of the motor 31 drives the front sprocket 32 ​​to rotate, which drives the chain to rotate. The slider 34 makes a circular motion at the lower end of the chain. The slider 34 slides back and forth inside the slide groove 35 at the same time, which drives the guide seat 33 to move back and forth. The guide seat 33 drives the air supply duct 44 to move synchronously. The air supply duct 44 is always located inside the guide seat 33 to prevent the air supply duct 44 from flipping.

[0026] Purification mechanism 2 includes a UV lamp 23 and a purification chamber 25. The purification chamber 25 is fixedly connected to the upper surface of the housing 1. UV lamps 23 are fixedly connected to both the left and right side walls of the purification chamber 25. Purification mechanism 2 also includes an exhaust duct 21, a induced draft fan 27, and an air supply duct 28. The exhaust duct 21 is provided on the front side of the purification chamber 25 and passes through a through hole on the front side of the housing 1. The air supply duct 28 is provided on the rear side of the purification chamber 25, and the lower end of the air supply duct 28 is connected to the middle of the rear side of the air supply trough 44. The induced draft fan 27 is fixedly connected to the rear end of the bottom wall of the purification chamber 25. The input end of the induced draft fan 27 is electrically connected to the output end of the control switch group 5. Purification mechanism 2 also includes a pre-filter 22, an activated carbon filter 24, and a HEPA filter 26. The pre-filter 22, activated carbon filter 24, and HEPA filter 26 are sequentially inserted into the bottom wall of the purification chamber 25 from front to back. The UV lamp 23 is located at the pre-filter... Between the primary filter 22 and the activated carbon filter 24, the exhaust fan 27 is located at the rear end of the HEPA filter 26. The exhaust fan 27 draws air from inside the elevator car into the purification box 25 through the exhaust duct 21. The primary filter 22 filters large particulate pollutants such as dust, hair, and dander, protecting the subsequent filters from being clogged by large particles and extending the lifespan of the activated carbon filter 24 and the HEPA filter 26. The activated carbon filter 24 adsorbs volatile organic compounds (formaldehyde, benzene, etc.), odors, and some gaseous pollutants. The HEPA filter 26 filters ultrafine particles (PM0.3 and above, such as bacteria, viruses, and allergens), ensuring the cleanliness of the output air. The UV lamp tube 23 irradiates and sterilizes the air. The purified air is sent into the air supply slot 44 through the air supply duct 28. The carbon brush of the negative ion generator 43 ionizes the air to generate negative ions. The air carrying negative ions enters the elevator car, further purifying the air inside the elevator car.

[0027] Air supply mechanism 4: It includes guide plate 41, guide groove 42, negative ion generator 43, air supply duct 44, and slide rod 45. The top wall of the housing 1 is fixedly connected to guide plates 41 that are symmetrically distributed on the left and right. The inner sides of the two guide plates 41 are provided with oppositely symmetrical guide grooves 42. The diameter of the front end of the guide groove 42 of the right guide plate 41 is larger than the diameter of the rear end, and the diameter of the rear end of the guide groove 42 of the left guide plate 41 is larger than the diameter of the front end. The upper end of the guide groove 42 is parallel to the horizontal plane. The slide rod 45 is slidably connected between the two guide grooves 42. The air supply duct 44 is fixedly connected to the middle of the slide rod 45. The air supply duct 44 is configured to cooperate with the purification box 25. The front side of the air supply duct 44 is fixedly connected to evenly distributed negative ion generators 43. The carbon brushes of the negative ion generators 43 are all fixedly connected to the bottom wall of the air supply duct 44. When the right end of the slide rod 45 is slidably connected to the upper end of the guide groove 42 on the right side, the left end of the slide rod 45 is slidably connected to the lower end of the guide groove 42 on the left side, so that the slide rod 45 is in an inclined state. At this time, the lower end of the air supply duct 44 is biased to the right, and the air with negative ions is blown to the right side of the elevator car. Continuing forward, the right end of the slide rod 45 rotates downward and slides inside the guide groove 42 on the right side, and the left end of the slide rod 45 rotates upward and slides inside the guide groove 42 on the left side. Then the slider 34 moves backward, causing the guide groove 42 to move backward. The left end of the slide rod 45 is located inside the section of the guide groove 42 on the left side that is parallel to the horizontal plane, and the right end of the slide rod 45 is located inside the inclined section of the guide groove 42 on the right side, so that the lower end of the air supply duct 44 is biased to the left, and the air with negative ions is blown to the left side of the elevator car, realizing large-area air supply.

[0028] It also includes a control switch group 5, which is located on the upper surface of the housing 1. The input end of the control switch group 5 is electrically connected to an external power source, and the input ends of the negative ion generator 43 and the UV lamp tube 23 are both electrically connected to the output end of the control switch group 5.

[0029] The working principle of the elevator car air purification and disinfection system provided by this utility model is as follows: By controlling the switch group 5 to turn on various electrical appliances, the exhaust fan 27 draws air from inside the elevator car into the purification box 25 through the exhaust duct 21. The pre-filter 22 filters large particulate pollutants such as dust, hair, and dander, protecting subsequent filters from clogging by large particles and extending the lifespan of the activated carbon filter 24 and HEPA filter 26. The activated carbon filter 24 adsorbs volatile organic compounds (formaldehyde, benzene, etc.), odors, and some gaseous pollutants. The HEPA filter 26 filters out ultrafine particulate matter (PM0.3 and above, such as bacteria, viruses, and allergens), ensuring the cleanliness of the output air. UV lamps 23 irradiate the air for sterilization. The purified air is then delivered into the air duct 44 through the air supply duct 28. The carbon brushes of the negative ion generator 43 ionize the air to generate negative ions. The air carrying these negative ions enters the elevator car, further purifying the air inside. Simultaneously, the output shaft of the motor 31 drives the front sprocket 32 ​​to rotate, which in turn drives the chain. The slider 34 is located at the lower end of the chain. The slider 34 moves in a circular motion, sliding back and forth inside the slide groove 35, causing the guide seat 33 to move back and forth. The guide seat 33 drives the air supply duct 44 to move synchronously. The air supply duct 44 is always located inside the guide seat 33 to prevent it from flipping. When the right end of the slider 45 is slidably connected to the upper end of the right guide groove 42, the left end of the slider 45 is slidably connected to the lower end of the left guide groove 42, causing the slider 45 to be in an inclined state. At this time, the lower end of the air supply duct 44 is tilted to the right, and air with negative ions is blown into the elevator car. Moving forward from the right side, the right end of the slide rod 45 rotates downward and slides inside the guide groove 42 on the right side, while the left end of the slide rod 45 rotates upward and slides inside the guide groove 42 on the left side. Subsequently, the slider 34 moves backward, causing the guide groove 42 to move backward. The left end of the slide rod 45 is located inside a section of the guide groove 42 on the left side that is parallel to the horizontal plane, while the right end of the slide rod 45 is located inside a section of the guide groove 42 on the right side that is inclined. This causes the lower end of the air supply duct 44 to be biased to the left, and the air with negative ions is blown to the left side of the elevator car, achieving large-area air supply.

[0030] It is worth noting that the control switch group disclosed in the above embodiments controls the operation of the induced draft fan 2 and the motor 31 using methods commonly used in the prior art. The control switch group 10 is provided with switch buttons that correspond one-to-one with the motor 21, the second motor 71 and the push rod 32 for controlling their switching operation.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
