Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator car technology, specifically to the ventilation structure of an elevator car. Background Technology
[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. The traction ropes are connected to the car and the counterweight at both ends and are wound around the traction sheave and guide sheave. The traction motor drives the traction sheave to rotate after being reduced in speed by a reducer. The traction force generated by the friction between the traction rope and the traction sheave realizes the lifting and lowering movement of the car and the counterweight to achieve the purpose of transportation. In order to ensure the freshness of the air inside the elevator car, it is necessary to ventilate the interior, which requires the use of a ventilation structure.
[0003] Existing elevator car ventilation technologies mostly achieve air exchange between the inside and outside of the car by installing fans and vents at the top or bottom of the car. Some designs add simple filtration devices to remove odors from the air; however, these traditional ventilation systems mainly focus on basic air replacement, have relatively limited functionality, and result in a poor passenger experience.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0020] Please see Figures 1-4 In this embodiment of the utility model, the ventilation structure of the elevator car includes the elevator car body 1, an air intake mechanism, and a purification mechanism.
[0021] In the specific implementation process, such as Figure 1 and Figure 3As shown, exhaust ports 2 are provided at the bottom of both sides of the elevator car body 1. Matching exhaust grilles 3 are installed inside the exhaust ports 2. An air intake mechanism is connected to the upper surface of the elevator car body 1. The air intake mechanism includes a housing 4, a fan 9, an air supply pipe 14, a first multi-way pipe 15, a first connecting pipe 16, an incense box 18, a first control valve 17, a second connecting pipe 22, a second control valve 23, a straight pipe 20, a third control valve 21, a second multi-way pipe 24, and an exhaust pipe 25. A housing 4 is installed on the lower inner surface of the elevator car body 1. A fan 9 is installed on the lower inner surface of the housing 4. The outlet of the fan 9 is connected to the first multi-way pipe 15 via the air supply pipe 14. The first multi-way pipe 15 is fixedly connected to the second multi-way pipe via the straight pipe 20. 24. A third control valve 21 is installed on the straight pipe 20. Two symmetrically arranged first connecting pipes 16 are fixedly connected to the first multi-port pipe 15. A first control valve 17 is installed on the first connecting pipe 16. Two symmetrically arranged incense boxes 18 are fixedly connected to the inner lower surface of the housing 4. The other end of the first connecting pipe 16 is fixedly connected to the side of the adjacent incense box 18. A second connecting pipe 22 is fixedly connected to the other side of the incense box 18. The other end of the second connecting pipe 22 is fixedly connected to the second multi-port pipe 24. A second control valve 23 is installed on the second connecting pipe 22. An exhaust pipe 25 is fixedly connected to the inner lower surface of the housing 4. The other end of the exhaust pipe 25 is fixedly connected to the second multi-port pipe 24. A purification mechanism is connected to the inlet of the fan 9.
[0022] It should be noted that during the process, when simple ventilation is required, the fan 9 is started and the third control valve 21 is opened. The fan 9 draws air in, allowing gas to enter the first multi-way pipe 15 through the air supply pipe 14. Since the first control valve 17 and the second control valve 23 are closed, the airflow can only enter the second multi-way pipe 24 through the straight pipe 20, and then enter the elevator car body 1 through the exhaust pipe 25, and finally exit through the exhaust port 2, completing the ventilation. If it is necessary to improve the smell inside the elevator car body 1, the fan 9 is started, and the corresponding incense box 18 is selected according to the desired fragrance. The first connecting pipe 16 and the second connecting pipe 2 connected to this incense box 18 (which contains volatile incense) are opened. The first control valve 17 and the second control valve 23 on the elevator car 1 allow gas to first enter the first multi-way pipe 15 through the gas supply pipe 14, and then enter the corresponding incense box 18 through the first connecting pipe 16 with the first control valve 17 open. The gas carries away the volatile fragrance. Then, the gas enters the second multi-way pipe 24 through the second connecting pipe 22 with the second control valve 23 open, and then enters the elevator car body 1 through the exhaust pipe 25, improving the smell inside the elevator car body 1. In summary, this device allows for the selection of different incense releases to create a specific atmosphere during the ventilation process of the elevator car, or the option to choose not to release incense and only perform pure ventilation. It has multiple functions and significantly improves the comfort and personalized experience of riding.
[0023] refer to Figure 3 and Figure 4 As shown, the purification mechanism includes an exhaust pipe 10, a purification box 11, a honeycomb integrated activated carbon block 26, and an outer pipe 12. The exhaust pipe 10 is fixedly connected to the inlet of the fan 9. The purification box 11 is fixedly connected to the inner lower surface of the shell 4. The purification box 11 is equipped with a matching honeycomb integrated activated carbon block 26. The other end of the exhaust pipe 10 is fixedly connected to one side of the purification box 11. The outer pipe 12 is fixedly connected to the other side of the purification box 11. The outer pipe 12 slides through the upper surface of the elevator car body 1.
[0024] It should be noted that during use, when the fan 9 is drawing air, the gas is first introduced into the purification box 11 through the outer pipe 12, where it is adsorbed and purified by the honeycomb integrated activated carbon block 26 to remove odors before being drawn away by the fan 9 through the exhaust pipe 10, thus avoiding odor pollution inside the elevator car body 1 or contamination of the incense burner 18.
[0025] refer to Figure 2 As shown, a conical air guide block 7 is fixedly connected to the lower surface of the housing 4 by multiple connecting rods 6. The conical air guide block 7 guides the airflow to the inner wall of the elevator car body 1, preventing the airflow from blowing directly onto the crowd.
[0026] refer to Figure 1 As shown in the figure, connecting blocks 5 are fixedly connected to both sides of the housing 4. The connecting blocks 5 are fixedly connected to the inner lower surface of the elevator car body 1 by bolts, making the disassembly and assembly of the housing 4 convenient and quick.
[0027] refer to Figure 2 As shown, the front and rear faces of the housing 4 are provided with inspection ports, and matching inspection doors 8 are installed in the inspection ports. The inspection doors 8 facilitate internal inspection and maintenance.
[0028] refer to Figure 3 As shown, the front end of the purification box 11 has a first passage cavity, and a matching first sealing door 13 is installed in the first passage cavity. The first sealing door 13 facilitates the replacement of the honeycomb integrated activated carbon block 26. The upper surface of the incense box 18 has a second passage cavity, and a matching second sealing door 19 is installed in the second passage cavity. The second sealing door 19 facilitates the addition of incense to the incense box 18.
