Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and specifically to an air-linked circulating elevator car. Background Technology
[0002] An elevator is a tool installed in a residential building to allow a single family to enter their home. Elevators are mainly classified into several types: traction elevators, screw elevators, and hydraulic elevators.
[0003] However, existing home elevators generally only have a single ventilation function, which makes the temperature inside the elevator car high in summer. Users feel very stuffy when riding the elevator, which affects the consumer experience. In addition, when some users bring food, the smell of the food is difficult to dissipate, which will cause odors in the elevator car over time, affecting the user's riding experience.
[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an elevator with an air circulation system. Utility Model Content
[0005] To solve the above problems, this utility model provides an air-linked circulating elevator car.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an air-linked circulating elevator car, comprising an elevator car, a fixed frame, a motor, and a motor frame as the main body; the motor is fixed to the center of the fixed frame through the motor frame, and the fixed frame is square; a main rotating gear is provided below the motor to cooperate with the rotation of the motor; a first linkage gear, a second linkage gear, a third linkage gear, and a fourth linkage gear are respectively provided at the four corners of the fixed frame; a pair of built-in fan groups and a pair of external fan groups are respectively provided on the fixed frame, and the pair of built-in fan groups and the pair of external fan groups are located at the top of the elevator car, the pair of built-in fan groups are connected to the first and second linkage gears, and the pair of external fan groups are connected to the third and fourth linkage gears.
[0007] Preferably, each of the first, second, third, and fourth linkage gears is provided with a driven shaft, through which the first, second, third, and fourth linkage gears are respectively mounted on a fixed frame and can rotate.
[0008] Preferably, the first, second, third, and fourth linkage gears are arranged in a ring-shaped, uniform arrangement around the axis of the drive gear.
[0009] Preferably, the pair of built-in fan assemblies are recessed within the fixing frame, and the pair of external fan assemblies protrude from the surface of the fixing frame.
[0010] Preferably, the motor frame is prismatic.
[0011] The beneficial effects of this utility model are: by using a motor to simultaneously drive a pair of built-in fan groups and a pair of external fan groups, the internal and external air circulation of the elevator car is realized, so that the air inside the elevator car can circulate. The structure is ingenious and the cost is low. Attached Figure Description

[0019] To make the technical solution of this utility model clearer, the present utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0020] like Figure 1-6As shown, the air-linked circulating elevator car of this utility model comprises an elevator car 1, a fixed frame 2, a motor 5, and a motor frame 51 as its main components. The motor 5 is fixed to the center of the fixed frame 2 via the motor frame 51, and the fixed frame 2 is square. A main rotating gear 6 is provided below the motor 5 to cooperate with its rotation. A first linkage gear 7, a second linkage gear 71, a third linkage gear 8, and a fourth linkage gear 81 are respectively provided at the four corners of the fixed frame 2. A pair of built-in fan groups 3 and a pair of external fan groups 4 are respectively provided on the fixed frame 2. The pair of built-in fan groups 3 and the pair of external fan groups 4 are located at the top of the elevator car 1. The pair of built-in fan groups 3 are connected to the first linkage gear 7 and the second linkage gear 71, and the pair of external fan groups 4 are connected to the third linkage gear 8 and the fourth linkage gear 81.
[0021] In this embodiment, the first linkage gear 7, the second linkage gear 71, the third linkage gear 8 and the fourth linkage gear 81 are respectively provided with driven rotating shafts 9. The first linkage gear 7, the second linkage gear 71, the third linkage gear 8 and the fourth linkage gear 81 are respectively mounted on the fixed frame 2 through the driven rotating shafts 9 and can rotate.
[0022] In this embodiment, the first linkage gear 7, the second linkage gear 71, the third linkage gear 8, and the fourth linkage gear 81 are arranged in a ring uniformly around the axis of the driving gear.
