Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically to a ventilation device for elevators. Background Technology

[0002] The ventilation system of an elevator is a key device to ensure air quality and maintain air circulation inside the elevator car. Its core function is to achieve air exchange between the inside and outside of the car through mechanical operation, so that passengers can continuously breathe fresh air during the ride.

[0003] Traditional elevators typically use ventilation fans for ventilation, and these fans are mostly fixedly installed on the top of the car (for example, the elevator ventilation method disclosed in utility model patent CN218410187U). In hot weather or when there are many passengers in the car, the airflow from the top ventilation fan is usually vertically downward or diagonally downward, and the airflow coverage is concentrated in the central area of ​​the top of the car. It is difficult to diffuse to the bottom of the car, corners, and areas near the elevator doors, which leads to a significant decrease in ventilation efficiency, cooling effect, and riding comfort. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ventilation device for elevators to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a ventilation device for an elevator, comprising an elevator car and a fan fixedly installed on the top of the elevator car. A guide box is fixedly connected to the inner wall of the elevator car. An air passage groove is horizontally opened inside the guide box, and an air outlet groove communicating with the air passage groove is vertically opened inside the guide box. An air outlet hole I communicating with the inside of the air passage groove is equidistantly opened on the top wall of the guide box, and an air outlet hole II communicating with the inside of the air outlet groove is equidistantly opened on the side wall of the guide box. The outer surface of the fan is fixedly connected to the inside of the guide box. A fixing frame is fixedly connected to the top of the inside of the air outlet groove. A silicone sealing block is slidably connected inside the fixing frame. A connecting plate is fixedly connected to the bottom of the silicone sealing block, and an adjustment component is installed on the end of the connecting plate away from the silicone sealing block.

[0006] Furthermore, the adjustment assembly includes a slide groove inside the flow guide box, a slider is longitudinally slidably connected inside the slide groove, the surface of the connecting plate is fixedly connected to the side of the slider, a limiting groove is formed inside the flow guide box, a sliding plate is longitudinally slidably connected inside the limiting groove, the surface of the slider away from the connecting plate is fixedly connected to the surface of the sliding plate, a second magnet is fixedly connected inside the flow guide box at the top of the limiting groove, and a first magnet is fixedly connected inside the flow guide box at the bottom of the limiting groove.

[0007] Furthermore, the fixed frame has an air vent inside, the silicone sealing block is an isosceles trapezoid, the shape of the air vent matches the shape of the silicone sealing block, and the outer surface of the silicone sealing block is sealed and adhered to the inner wall of the air vent.

[0008] Furthermore, the slide plate is made of iron and is U-shaped, with the end of the connecting plate extending into the interior of the groove.

[0009] Furthermore, the top of the skateboard is magnetically fixed to the surface of the second magnet, and the output end of the second air outlet faces downward.

[0010] Furthermore, the output end of the fan extends into the interior of the air passage and is connected to the interior of the air passage.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by setting up air passage and air outlet grooves inside the air guide box, in conjunction with air outlet one on the top wall and air outlet two on the side wall, breaks the limitation of traditional top ventilation fans where airflow is concentrated in the center of the car top. When it is necessary to expand the ventilation range, the silicone sealing block can be slid by adjusting the component, so that airflow can be discharged from top air outlet one and side wall air outlet two at the same time, covering the bottom of the car, corners and areas near the elevator door, significantly improving ventilation efficiency and cooling effect. In addition, the output end of air outlet two faces downward, which can more accurately deliver air to the lower part of the car, avoiding airflow blowing directly on passengers and causing discomfort, greatly improving riding comfort. At the same time, the opening and closing state of the silicone sealing block can be controlled by manually adjusting the sliding plate, realizing flexible switching between top air outlet and side air outlet to meet the ventilation needs in different scenarios.

[0013] 2. In this utility model, the silicone sealing block adopts an isosceles trapezoidal design, which precisely matches the shape of the air passage hole of the fixed frame, ensuring a tight fit during sealing, effectively preventing air leakage when there is no need for lateral air outlet, and ensuring the concentration of air outlet at the top. The adjustment component uses magnet one and magnet two to magnetically fix the sliding plate made of iron plate, which can not only firmly maintain the position of the silicone sealing block after sliding, preventing the state deviation caused by elevator vibration, but also allow passengers to easily switch the air outlet mode without complicated operation steps.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] A ventilation device for an elevator includes an elevator car 1 and a fan 3 fixedly installed on the top of the elevator car 1. A guide box 2 is fixedly connected to the inner wall of the elevator car 1. An air passage 4 is opened horizontally inside the guide box 2. An air outlet 6 communicating with the air passage 4 is opened vertically inside the guide box 2. An air outlet hole 5 communicating with the inside of the air passage 4 is opened at equal intervals on the top wall of the guide box 2. An air outlet hole 7 communicating with the inside of the air outlet 6 is opened at equal intervals on the side wall of the guide box 2. The outer surface of the fan 3 is fixedly connected to the inside of the guide box 2. A fixing frame 8 is fixedly connected to the top of the inside of the air outlet 6. A silicone sealing block 9 is slidably connected inside the fixing frame 8. A connecting plate 10 is fixedly connected to the bottom of the silicone sealing block 9. An adjustment component 11 is installed on the end of the connecting plate 10 away from the silicone sealing block 9.

[0023] In this embodiment, the airflow generated by the fan 3 passes through the air passage 4 inside the guide box 2 and can be discharged through the air outlet 5 on the top wall and the air outlet 7 on the side wall respectively. This breaks through the limitation of traditional ventilation fans that can only exhaust air in the center of the top of the elevator car 1. By adjusting the position of the silicone sealing block 9 by adjusting the component 11, the mode of top air outlet, side air outlet or both can be flexibly switched to expand the airflow coverage, improve ventilation efficiency and cooling effect. The air outlet 7 opens downward to avoid the airflow blowing directly on passengers and improve riding comfort.

[0024] Specifically, the adjustment component 11 includes a groove 111 inside the flow guide box 2, a slider 112 is longitudinally slidably connected inside the groove 111, the surface of the connecting plate 10 is fixedly connected to the side of the slider 112, a limiting groove 114 is opened inside the flow guide box 2, a sliding plate 113 is longitudinally slidably connected inside the limiting groove 114, the surface of the slider 112 away from the connecting plate 10 is fixedly connected to the surface of the sliding plate 113, a second magnet 116 is fixedly connected to the top of the limiting groove 114 inside the flow guide box 2, and a first magnet 115 is fixedly connected to the bottom of the limiting groove 114 inside the flow guide box 2.

[0025] In this embodiment, in the adjustment component 11, the slider 112 slides in the slide groove 111, driving the connecting plate 10 and the silicone sealing block 9 to move synchronously, thereby controlling the opening and closing of the air outlet groove 6. The limiting groove 114 restricts the sliding direction of the slide plate 113 to ensure the stability of the adjustment process. Magnet 115 and Magnet 216 magnetically fix the iron plate slide plate 113, which can not only firmly maintain the position of the silicone sealing block 9 after adjustment (avoiding the state deviation caused by elevator vibration), but also allow users to easily switch the air outlet mode without complicated steps.

[0026] Specifically, the fixed frame 8 has an air vent 81 inside, and the silicone sealing block 9 is an isosceles trapezoid. The shape of the air vent 81 matches the shape of the silicone sealing block 9, and the outer surface of the silicone sealing block 9 is sealed and attached to the inner wall of the air vent 81.

[0027] In this embodiment, the silicone sealing block 9 is an isosceles trapezoid, which precisely matches the shape of the air passage hole 81 of the fixed frame 8, and the outer surface is sealed to fit the inner wall of the air passage hole 81. When the silicone sealing block 9 is closed, it can completely block the connection between the air passage groove 4 and the air outlet groove 6, avoid air leakage when there is no need for lateral air outlet, and ensure the concentration of air outlet at the top air outlet hole 5; when open, it can smoothly guide the airflow and ensure the efficiency of lateral air outlet.

[0028] Specifically, the slide plate 113 is made of iron plate and is U-shaped, with the end of the connecting plate 10 extending into the interior of the groove 111.

[0029] In this embodiment, the slide plate 113 is made of iron plate and is "U" shaped, which is convenient for manual operation by the user (increasing the grip contact area) and can be stably magnetically attracted and fixed with magnet 115 and magnet 216. The end of the connecting plate 10 extends into the slide groove 111 to ensure the connection stability between the slider 112 and the slide plate 113, avoid the parts from falling off or getting stuck during the adjustment process, and ensure the durability of the overall structure.

[0030] Specifically, the top of the slide plate 113 is magnetically fixed to the surface of the magnet 116, and the output end of the air outlet 7 faces downward.

[0031] In this implementation scheme, when the top of the slide plate 113 is magnetically fixed to the magnet 116, the silicone sealing block 9 tightly closes the air vent 81, ensuring that the side air outlet is completely closed; when the bottom is magnetically fixed to the magnet 115, the air vent 81 is fully open, the side air outlet is stable, and the outlet 7 has its output end facing downward, which can guide the airflow to the lower part of the car, covering the area that traditional ventilation fans cannot reach, while avoiding the airflow blowing directly onto the passenger's face or body, thus improving the riding comfort.

[0032] Specifically, the output end of the fan 3 extends into the interior of the air passage 4 and is connected to the interior of the air passage 4.

[0033] In this embodiment, the output end of the fan 3 extends directly into and connects to the inside of the air passage 4, reducing losses during airflow transmission and ensuring that the air volume generated by the fan 3 can efficiently enter the air passage 4 and then be discharged through the air outlet 5 or the air passage 6 and the air outlet 7.

[0034] The working principle and usage process of this utility model are as follows: When in use, after starting the fan 3, the airflow enters the air passage 4 through the fan 3 and then flows out through the air outlet 5. When it is necessary to increase the air outlet range, the people inside the elevator car 1 can pull down the corresponding sliding plate 113. The sliding plate 113, through the slider 112 and the connecting plate 10, drives the silicone sealing block 9 to slide downwards. When there is a gap between the outer surface of the silicone sealing block 9 and the inner wall of the air passage 81, the airflow inside the air passage 4 passes through the air passage 81 and enters the outlet. The air flows out through the second air outlet 7 inside the air groove 6, allowing for multi-angle and selective adjustment of the air outlet range inside the elevator car 1. When the slide plate 113 slides to the bottom of the limit groove 114, the surface of the slide plate 113 is attracted to the surface of the first magnet 115, which can improve the stability of the air outlet. When lateral air outlet is not needed, slide the slide plate 113 upward. After the slide plate 113 is magnetically attracted and fixed by the second magnet 116, the outer surface of the silicone sealing block 9 is sealed and attached to the inside of the air outlet 81. At this time, the second air outlet 7 stops air outlet.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
