Description

Technical Field

[0001] This utility model relates to the field of elevator air purification technology, and in particular to an air purification and ventilation device for elevators. Background Technology

[0002] The air circulation inside elevators is poor, often resulting in unpleasant odors. Furthermore, some inconsiderate individuals may sample the air inside, further polluting the air quality. Therefore, air purification devices are necessary. However, these devices have several shortcomings and areas for improvement: 1. While filters are typically used to remove odors, they require replacement every one to three months. The metal plates holding the filters in place with bolts complicate replacement. 2. During air purification, the direction of the airflow cannot be easily changed, hindering the effective use of airflow to alter airflow and achieve cooling. Therefore, we propose an air purification and ventilation device for elevators. Utility Model Content

[0003] The main objective of this invention is to provide an air purification and ventilation device for elevators, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An air purification and ventilation device for elevators includes a housing. Mounting plates are fixedly connected to the left front, right front, left rear, and right rear of the housing. Ultraviolet lamps are fixedly connected to the middle front and middle rear of the housing. A set of limiting plates is fixedly connected to the upper front and upper rear inner walls of the housing. A purification mechanism is provided between the two sets of limiting plates. Exhaust fans are fixedly connected to the left and right sides inside the housing. Positioning holes are provided on the upper left front and upper left rear of the housing. An adjustment mechanism is provided at the lower part of the housing.

[0005] Preferably, the purification mechanism includes an upper cover plate and a lower cover plate. The lower left and lower right ends of the upper cover plate are fixedly connected with snap-fit ​​rods. The upper left and upper right ends of the lower cover plate are both provided with snap-fit ​​holes. The front left and rear left ends of the upper cover plate are fixedly connected with extension plates. Positioning rods are provided on both sets of extension plates. An activated carbon filter plate is snapped between the upper cover plate and the lower cover plate.

[0006] By adopting the above technical solution, activated carbon filter plates can absorb odors and some toxic substances in the passing airflow.

[0007] Preferably, the upper cover plate and the lower cover plate are engaged together between the two sets of limiting plates, and the engaging rod is engaged with the engaging hole.

[0008] By adopting the above technical solution, the snap-fit ​​rod and snap-fit ​​hole can be snapped together, so that the activated carbon filter plate can be fixed inside when the upper cover plate and the lower cover plate are connected.

[0009] Preferably, the positioning rod is inserted and engaged with the nearby positioning hole, the purification mechanism is located above the exhaust fan, and the exhaust fan is located above the adjustment mechanism.

[0010] By adopting the above technical solution, the position of the upper cover plate can be fixed by engaging the positioning rod with the positioning hole.

[0011] Preferably, the adjustment mechanism includes several sets of rotating rods, each set of rotating rods having a flip plate fixedly connected to it, each set of rotating rods having a drive gear fixedly connected to its rear end, each set of drive gears having a snap-fit ​​belt sleeved on its exterior, and the leftmost rotating rod having a rotating handle fixedly connected to its front end.

[0012] By adopting the above technical solution, the snap-on belt can drive the gear and the front rotating rod and the flip plate to rotate.

[0013] Preferably, several sets of the rotating rods are interlocked and engaged with the outer casing, and several sets of the flip plates are located inside the outer casing.

[0014] By adopting the above technical solution: the front of the rotating rod on the left is threaded with a nut, which can contact the front of the outer shell to allow the rotating rod to rotate automatically and fix the position of the flip plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a purification mechanism, the activated carbon filter plate on the purification mechanism can absorb odors and harmful substances in the airflow. At the same time, the upper cover plate and the lower cover plate are located between the limiting plate, which can easily limit the position of the purification mechanism. The positioning rod is used to lock the position with the positioning hole, and the other side is to disassemble and replace it. The operation is simple.

[0016] 2. By setting an adjustment mechanism, the flip plate on the adjustment mechanism can rotate the handle, drive the gears and engage the belt to change the angle, thereby changing the angle of the outflowing airflow. The angle of the airflow makes it easier to adjust the airflow inside the elevator, and facilitates the air inside the elevator to rise and come into contact with the exhaust fan.

[0022] Please see Figure 1-4 This utility model provides a technical solution: An air purification and ventilation device for elevators includes an outer shell 1. Mounting plates 2 are fixedly connected to the left front end, right front end, left rear end, and right rear end of the outer shell 1. Ultraviolet lamps 3 are fixedly connected to the middle front end and middle rear end of the outer shell 1. A set of limiting plates 4 are fixedly connected to the upper front inner wall and the upper rear inner wall of the outer shell 1. A purification mechanism 5 is provided between the two sets of limiting plates 4. Exhaust fans 6 are fixedly connected to the left and right sides inside the outer shell 1. Positioning holes 7 are opened on the upper left front end and the upper left rear end of the outer shell 1. An adjustment mechanism 8 is provided at the lower part of the outer shell 1.

[0023] In this embodiment, the purification mechanism 5 includes an upper cover plate 9 and a lower cover plate 10. The lower left and lower right ends of the upper cover plate 9 are fixedly connected with snap-fit ​​rods 11. The upper left and upper right ends of the lower cover plate 10 are both provided with snap-fit ​​holes 12. The front left and rear left ends of the upper cover plate 9 are fixedly connected with extension plates 13. Positioning rods 14 are provided on both sets of extension plates 13. An activated carbon filter plate 15 is snapped between the upper cover plate 9 and the lower cover plate 10. The upper cover plate 9 and the lower cover plate 10 are snapped between two sets of limiting plates 4. The snap-fit ​​rods 11 are snapped with the snap-fit ​​holes 12. The positioning rods 14 are inserted and snapped with the nearby positioning holes 7. The purification mechanism 5 is located above the exhaust fan 6. The exhaust fan 6 is located above the adjustment mechanism 8.

[0024] Through the above scheme: the upper cover plate 9 and the lower cover plate 10 are connected to each other by the snap-fit ​​rod 11 and the snap-fit ​​hole 12, so that the activated carbon filter plate 15 is locked in the middle. The positioning rod 14 on the upper cover plate 9 is connected to the positioning hole 7 by the extension plate 13, so that the position of the purification mechanism 5 can be fixed, making it easy to replace and reducing the difficulty of use.

[0025] In this embodiment, the adjustment mechanism 8 includes several sets of rotating rods 16, each set of rotating rods 16 is fixedly connected to a flip plate 17, each set of rotating rods 16 is fixedly connected to a drive gear 18 at its rear end, each set of drive gears 18 is connected to a snap-fit ​​belt 19, the leftmost rotating rod 16 is fixedly connected to a rotating handle 20 at its front end, each set of rotating rods 16 is inserted into and snapped into the outer shell 1, and each set of flip plates 17 is located inside the outer shell 1.

[0026] Through the above scheme, the flip plate 17 can swing left and right under the action of the rotating handle 20, thereby changing the direction of the airflow. The airflow will mobilize the air inside the elevator and accelerate air purification.

[0027] It should be noted that this utility model is an air purification and ventilation device for elevators. During use, the purification device is first installed on the upper wall of the elevator using the mounting plate 2. Simultaneously, the internal exhaust fan 6 and ultraviolet lamp 3 are connected to the elevator's electrical wiring for power. After installation, the internal exhaust fan 6 is turned on via an external system. The exhaust fan 6 directs airflow through the activated carbon filter plate 15 at the top, adsorbing harmful substances and odors in the airflow. The airflow then flows out along the lower part of the outer casing 1. In summer, adjusting the flip plate 17 vertically allows the airflow to blow directly downwards to cool the people in the elevator. In winter... The flip plate 17 can be flipped to the right, allowing airflow to flow along the upper right without contacting people in the elevator. The outflowing airflow rises the air that was originally below, and is then drawn by the exhaust fan 6 to form an airflow, completing the circulation of air inside the elevator. At night, the ultraviolet lamp 3 can be turned on using a timer switch to disinfect the inside of the elevator and prevent excessive bacteria. After a period of use, the positioning rod 14 on the extension plate 13 can be pulled out from the positioning hole 7 to remove the purification mechanism 5. After pulling it out, the upper cover plate 9 and the lower cover plate 10 can be pried open to replace the internal activated carbon filter plate 15. Then, the purification mechanism 5 can be installed on the outer shell 1 in reverse.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
