Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0022] Combined with Figures 1 - 3 , an elevator energy-saving device includes a car body 1. A fan 2 is provided on the inner wall of the car body 1. An infrared sensor 3 is provided on one side of the fan 2, and a concentration sensor 4 is provided on the other side of the fan 2. A control panel 5 is provided on the inner wall of the car body 1. The fan 2, the infrared sensor 3, and the concentration sensor 4 are all signal-connected to the control panel 5.

[0023] The present utility model will be further described below in conjunction with the embodiments.

[0024] Embodiment 1:

[0025] Please refer to Figures 1 - 4 , the fan 2 is a variable-frequency fan, which can adjust the speed according to needs and save electricity. When the infrared sensor 3 detects that someone enters or leaves the car body 1, the wind speed can be automatically adjusted to maintain the air circulation in the car body 1.

[0026] An induction lamp 6 is provided on the inner wall of the car body 1, which automatically turns on and off according to the entry and exit of personnel, avoiding power waste when there is no one.

[0027] An installation block 7 is provided on the inner wall of the car body 1. The upper surface of the installation block 7 is threadedly connected with a grid plate 71. A cushion block is provided on the upper surface of the grid plate 71, and the upper surface of the cushion block is in contact with the bottom of the fan 2, providing a stable installation foundation for the fan 2. At the same time, the grid plate 71 plays a certain protective role. If a relatively high object enters the car body 1, it can prevent its top from colliding with the fan 2, the infrared sensor 3, and the concentration sensor 4.

[0028] A connecting rod 11 is provided on the inner wall of the car body 1. A protective cover 8 is provided at the bottom of the connecting rod 11. One side of the fan 2 is connected to the bottom of the connecting rod 11, reducing the entry of dust into the fan 2.

[0029] The inner wall of the protective cover 8 is provided with a sound-absorbing layer 81. The outer surface of the fan 2 is in contact with the inner side of the sound-absorbing layer 81. The sound-absorbing layer 81 is a component made of mineral wool. The mineral wool material has good sound-absorbing effect and is not easy to burn. Therefore, it can not only reduce the noise generated during the operation of the fan 2, but also does not affect the fire protection requirements of the elevator.

[0030] The inner wall of the car body 1 is provided with a deodorizing box 9. An activated carbon packet is placed inside the deodorizing box 9 to adsorb the peculiar smell inside the car body 1 and keep the air fresh.

[0031] Specifically, when the elevator is running, when the infrared sensor 3 detects that a person enters the elevator, the fan 2 can be started. Combined with the concentration sensor 4, when there is no one or a high concentration of carbon dioxide is not detected, the operation frequency of the fan 2 can be turned off or reduced to reduce energy consumption; when a high concentration of carbon dioxide is detected, the air volume can be increased to keep the air fresh. Also, because the fan 2, the infrared sensor 3 and the concentration sensor 4 are all signal-connected to the control panel 5, it can also be set or forced to stop through the control panel 5 for convenient later maintenance. At the same time, because the inner wall of the car body 1 is provided with an induction lamp 6, it automatically turns on and off according to the entry and exit of people, avoiding power waste when there is no one. In addition, the inner wall of the car body 1 is threadedly connected with a grid plate 71 through a mounting block 7, and is in contact with the bottom of the fan 2 through a cushion block on the upper surface of the grid plate 71. Therefore, it can not only provide a stable installation foundation for the fan 2, and at the same time the grid plate 71 plays a certain protective role. If a relatively high object enters the car body 1, it can prevent its top from colliding with the fan 2, the infrared sensor 3 and the concentration sensor 4. Also, because a protective cover 8 is provided at the bottom of the connecting rod 11, the fan 2 is connected to the inner wall of the car body 1 through the connecting rod 11, and the inner wall of the protective cover 8 is provided with a sound-absorbing layer 81 made of mineral wool. Therefore, it can not only reduce the entry of dust into the fan 2 and reduce the noise generated during the operation of the fan 2, but also does not affect the fire protection requirements of the elevator. Finally, because the inner wall of the car body 1 is provided with a deodorizing box 9 and an activated carbon packet is placed inside the deodorizing box 9, it can adsorb the peculiar smell inside the car body 1 and keep the air fresh, and the activated carbon packet can be replaced during regular maintenance. In summary, this device not only helps to save energy and reduce emissions, but also improves the riding experience of passengers.
