Description

Technical Field

[0001] This utility model belongs to the field of elevator car ventilation technology, and in particular relates to an elevator car with ventilation function. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used in multi-story buildings to transport people or goods. The elevator car is the box-shaped space used to carry and transport people and goods. Elevator spaces are usually small, so a ventilation system is needed to exchange air inside. Currently, some elevator cars only have one exhaust fan for exhaust, which can easily lead to poor air circulation inside the car.

[0003] Elevator cars primarily serve to carry people and goods and are generally enclosed spaces. During prolonged use, due to the high volume of people moving around, odors can easily develop inside the elevator car. These odors can significantly reduce the riding experience, and the enclosed space can easily breed bacteria, which can be transmitted to people directly or indirectly, affecting their health. Therefore, we have proposed an elevator car with ventilation capabilities. Utility Model Content

[0004] The purpose of this invention is to provide an elevator car with ventilation function. This is achieved by setting a rotating disc, specifically by gears driving the disc to rotate via toothed grooves. The rotating disc, through three inner arc-shaped grooves, drives a moving column, which in turn moves an opening / closing plate. A limiting plate restricts the opening / closing plate, allowing it to move only along its path. This enables a motor to mechanically open the opening / closing plate, opening the ventilation vent. A fan then expels air from the car and introduces fresh air, reducing the possibility of bacterial growth. This invention solves the problem that existing elevator cars, primarily used for carrying passengers and goods and generally enclosed spaces, easily develop odors during prolonged use due to high passenger flow. These odors significantly reduce the riding experience, and the enclosed space easily breeds bacteria, indirectly or directly affecting people's health.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an elevator car with ventilation function, including an elevator car, with fixed seats fixedly connected to the left and right sides of the elevator car, electric push rods fixedly connected inside the two fixed seats, and ventilation plates fixedly connected to the bottom of the two electric push rods.

[0007] An outer shell is fixedly connected to the top of the elevator car. An exhaust vent is located on the top of the outer shell. Two limiting semi-rings are fixedly connected to the top of the outer shell. A rotating disk is rotatably connected to the inner side of the top of each limiting semi-ring. A toothed groove is located on the right side of the rotating disk, and a gear is meshed with the right side of the toothed groove. A second motor is fixedly connected to the inner side of the top of the outer shell. The bottom output end of the second motor is fixedly connected to the top of the gear. Three arc-shaped grooves are located on the surface of the rotating disk. A moving column is slidably connected inside each arc-shaped groove. Three opening and closing plates are rotatably connected to the bottom of the rotating disk. The top of each opening and closing plate is fixedly connected to the bottom of the moving column. The opening and closing plates allow the car to freely change between closed and ventilated states, effectively maintaining the temperature inside the car during winter.

[0008] Each of the three opening and closing plates has a fixed limit plate on its opposite side. Two limit strips are slidably connected to the outer surface of the limit plate. The bottom of the limit strips is fixedly connected to the top of the elevator car. A rotating shaft is in contact with the opposite side of the three opening and closing plates. A motor is fixedly connected to the inner side of the top of the elevator car. The bottom output end of the motor is fixedly connected to the top of the rotating shaft. An inner filter is in contact with the bottom of the opening and closing plate. The center of the inner filter is rotatably connected to the outer surface of the rotating shaft. An outer filter is fixedly connected to the outer surface of the rotating shaft. The outer surface of the outer filter is fixedly connected to the inner side of the top of the elevator car. A ventilation fan is fixedly connected to the outer surface of the rotating shaft. The second motor drives the opening and closing plate to open outward through mechanical linkage. At this time, the ventilation port is opened, and the air in the car is exhausted and fresh air is introduced through the fan, reducing the possibility of bacterial growth.

[0009] External frames are fixedly connected to the left and right sides of the elevator car. The interior of the external frames is inserted into the outer surface of the ventilation panels. Two round rods are fixedly connected to the top of the ventilation panels. Two limiting blocks are slidably connected to the outer surface of the round rods. The side of the limiting blocks closest to the elevator car is fixedly connected to the surface of the elevator car. A square filter screen is provided on the opposite side of the two ventilation panels. The outer surface of the square filter screen is fixedly connected to the interior of the elevator car. Several protective rods are provided on the side of the square filter screen away from the ventilation panels. The top and bottom of the protective rods are fixedly connected to the interior of the elevator car. The square filter screen also serves to filter a large amount of dust in the air, creating a good cabin environment.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model uses a rotating disk, specifically a gear that drives the rotating disk to rotate through the tooth grooves on the rotating disk. The rotating disk drives the moving column to move through three arc-shaped grooves on its inner side. The moving column drives the opening and closing plate to move. The limiting plate limits the opening and closing plate, so that it can only move along the path of the limiting plate. In this way, the motor drives the opening and closing plate to open outward through mechanical linkage. At this time, the ventilation port is opened, and the fan exhausts the air in the car and introduces fresh air, reducing the possibility of bacterial growth.

[0012] 2. This utility model protects the square filter screen by setting up a protective bar, which avoids damage to the protective bar caused by most unintentional collisions by passengers and impacts by cargo. This improves the service life of the square filter screen to a certain extent. The square filter screen also filters out a large amount of dust in the air, creating a good cabin environment.

[0025] Please see Figure 1-7 As shown, this utility model is an elevator car with ventilation function, including an elevator car 1. The elevator car 1 has fixed seats 2 fixedly connected to the left and right sides of the elevator car 1. Electric push rods 23 are fixedly connected inside the two fixed seats 2.

[0026] An outer shell 4 is fixedly connected to the top of the elevator car 1. An exhaust vent 3 is located on the top of the outer shell 4.

A toothed groove 431 is located on the right side of the rotating disk 43, and a gear 47 is meshed with the right side of the toothed groove 431. A second motor 45 is fixedly connected to the inner side of the top of the outer shell 4. The bottom output end of the second motor 45 is fixedly connected to the top of the gear 47. Three arc-shaped grooves are formed on the surface of the rotating disk 43, and a moving column 432 is slidably connected inside the arc-shaped grooves. This utility model... By setting a rotating disk 43, specifically, a gear 47 drives the rotating disk 43 to rotate through the tooth groove 431 on the rotating disk 43. The rotating disk 43 drives the moving column 432 to move through the three arc-shaped grooves on the inner side. The moving column 432 drives the opening and closing plate 49 to move. The limiting plate 46 limits the opening and closing plate 49, so that it can only move along the path of the limiting plate 46. In this way, the motor 45 drives the opening and closing plate 49 to open outward through mechanical linkage. At this time, the ventilation port is opened, and the air in the car is exhausted and fresh air is introduced through the fan, reducing the possibility of bacterial growth.

[0027] The bottom of the rotating disk 43 is rotatably connected to three opening and closing plates 49. The top of the opening and closing plates 49 is fixedly connected to the bottom of the moving column 432. The opposite sides of the three opening and closing plates 49 are fixedly connected to limit plates 46. The outer surface of the limit plates 46 is slidably connected to two limit strips 44. The bottom of the limit strips 44 is fixedly connected to the top of the elevator car 1.

[0028] Three hinged plates 49 are in contact with a rotating shaft 48 on opposite sides. A motor 42 is fixedly connected to the inner top of the elevator car 1. The bottom output end of the motor 42 is fixedly connected to the top of the rotating shaft 48. An inner filter 491 is in contact with the bottom of the hinged plates 49. The center of the inner filter 491 is rotatably connected to the outer surface of the rotating shaft 48. An outer filter 492 is fixedly connected to the outer surface of the rotating shaft 48. The outer surface of the outer filter 492 is fixedly connected to the inner top of the elevator car 1. A ventilation fan 481 is fixedly connected to the outer surface of the rotating shaft 48.

[0029] External frames 21 are fixedly connected to the left and right sides of the elevator car 1. The interior of the external frames 21 is inserted into the outer surface of the ventilation panels 24. Two round rods 25 are fixedly connected to the top of the ventilation panels 24. Two limiting blocks 22 are slidably connected to the outer surface of the round rods 25. The side of the limiting blocks 22 closest to the elevator car 1 is fixedly connected to the surface of the elevator car 1. A square filter screen 27 is provided on the opposite side of the two ventilation panels 24. The outer surface of the square filter screen 27 is fixedly connected to the interior of the elevator car 1. Several protective rods 26 are provided on the side of the square filter screen 27 away from the ventilation panels 24. The top and bottom of the protective rods 26 are fixedly connected to the interior of the elevator car 1. This utility model protects the square filter screen 27 by setting the protective rods 26, avoiding damage to the protective rods 26 caused by most unintentional collisions by passengers and impacts by goods. It also improves the service life of the square filter screen 27 to a certain extent. The square filter screen 27 also filters a large amount of dust in the air, creating a good car environment.

[0030] A specific application of this embodiment is as follows: First, the second motor 45 is started. As the second motor 45 starts, it begins to drive the connected gear 47 to rotate slowly. The tooth surface of the gear 47 meshes tightly with the tooth groove 431 on the rotating disk 43. Through the gear transmission mechanism, the rotational force of the gear 47 is transmitted to the rotating disk 43. The rotating disk 43 begins to rotate under the drive of the gear 47. Its surface is designed with three inner arc-shaped grooves. These arc-shaped grooves cooperate with the bottom of the moving column 432 to form a unique mechanical linkage structure. When the rotating disk 43 rotates, it guides the moving column 432 to move along a specific path. The moving column 432 begins to move under the drive of the rotating disk 43. One end of it is connected to the opening and closing plate 49. Therefore, when the moving column 432 moves, it also drives the opening and closing plate 49 to move together. In order to ensure that the opening and closing plate 49 can move accurately according to the predetermined path, the limiting plate 46 can effectively restrict the movement direction of the opening and closing plate 49, so that it can only move along the limiting plate 46. As the elevator moves along its path, the opening plate 49 gradually opens outward under the continuous drive of motor 45. As the opening plate 49 moves, the ventilation opening is also gradually opened. Next, motor 42 is started, which drives the rotation of shaft 48. Shaft 48 is connected to ventilation fan 481. Therefore, when shaft 48 rotates, it also drives ventilation fan 481 to rotate. Ventilation fan 481 starts to rotate under the drive of shaft 48. At the same time, electric push rod 23 is started, reducing its length. Its shortening causes the ventilation plate 24 connected to it to move upward. Ventilation plate 24 originally blocked the air inlet below. As it moves upward, the air inlet is gradually opened. At this time, the air inlet below is fully open, and the air inside the elevator car begins to fully exchange with the outside. Fresh air rushes into the car through the air inlet, while the stale air inside the car is carried out of the car by the airflow generated by ventilation fan 481. In this way, the elevator car completes the ventilation process.
