[0002] With the progress of society and the improvement of quality of life, people are paying more and more attention to the air quality in public spaces, especially in elevator cabins. Existing elevator cabins often have problems such as poor air circulation and poor air quality. Especially in high-rise buildings, elevators are enclosed spaces with high frequency of use, and the air quality directly affects the comfort and health of users.

[0003] In the prior art, although there are some basic ventilation facilities inside the elevator car, they often lack effective air purification means, and are unable to effectively filter suspended particles and harmful gases in the air and adjust the temperature and humidity in the elevator car. In addition, the lighting, air supply and other functional modules inside the elevator are usually designed independently, resulting in low equipment integration, large space occupation, and difficulty in maintenance and management.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0036] Those skilled in the art should understand that, in the disclosure of the present application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present application.

[0037] like Figure 1-2 As shown, the specific structure of the air replacement system is as follows:

[0038] First, the air replacement system includes an elevator car 1. A specific installation position is provided at the top of the elevator car 1. The area is used to install an aluminum gusset plate ceiling 2, and ventilation holes are provided under the ceiling for fresh air to enter. A plurality of air outlet panels 12 are provided at the bottom of the elevator car 1 to discharge the purified air.

[0039] The aluminum gusset plate ceiling 2 is installed according to a preset standard size (300x600mm or 300x300mm) to ensure quick installation and replacement, and installation holes for installing the ceiling fan assembly 5 are preset inside the ceiling.

[0040] The control switch 3 is fixed on the key panel of the elevator car 1 and is used to control the operating state of the entire system. The external air purification component 4 is installed on the outside of the ventilation hole of the elevator car 1 and is equipped with a ventilation pipe 41. The outlet of the ventilation pipe 41 is equipped with a first air filter layer component 42, which is built into the air purification component and includes a primary filter, an electrostatic dust collection layer, a medium-efficiency filter and a high-efficiency filter to filter the fresh air entering the elevator car 1 step by step to remove various pollutants.

[0041] The fan assembly 5 is designed to be detachable and can be easily installed in the reserved hole of the aluminum gusset plate ceiling 2, and is connected to the outside air through the ventilation pipe 41. The fan assembly 5 is electrically connected to the control switch 3 to realize intelligent operation. The fan assembly 5 has two centrifugal fans driven by DC variable frequency motors integrated inside, and the air volume can be adjusted according to actual needs, which saves energy and improves the air supply efficiency. In addition, the fan assembly 5 also includes an LED light board 51 with a power of not less than 18 watts. It adopts a cold light source design to meet the internal lighting needs of the elevator car 1 while reducing energy consumption. The specific principle of the fan assembly of the present application is the existing technology, so it can also be replaced by the fan assembly currently sold on the market, or even the bathroom heater.

[0042] In order to increase the riding comfort, the air outlet 52 of the cooler assembly 5 is equipped with swing blades controlled by a driving motor, which can flexibly adjust the air supply direction to avoid blowing directly to the passengers. At the same time, the cooler assembly 5 is also equipped with a temperature sensor and a display panel, which can monitor and display the internal temperature of the elevator car 1 in real time, which is helpful for users to understand the environmental status of the elevator car 1 and support the system to perform automatic temperature control. For example, when the temperature is high, the two centrifugal fans are turned on to start air supply, and when the temperature is low, the wind speed is automatically turned off or reduced, and the wind is directed to a position where it will not blow to people, to ensure smooth ventilation.

[0043] Finally, wire holes are reserved in advance on some aluminum gussets of the aluminum gusset ceiling 2 to facilitate concealed wiring, making the entire system layout neater and more orderly, while also greatly improving the convenience of the installation process and the safety and reliability of the system. For example, monitoring probes can be installed later to facilitate wiring, and sockets can be reserved in the space above the aluminum gusset ceiling 2 to facilitate later installation.

[0044] Through the above technical scheme, the utility model realizes the integrated integration of air purification, ventilation and lighting functions inside the elevator car 1, purifies the air entering the elevator car 1 from the source, ensures the air quality inside the elevator car 1 through multiple filtration, and greatly improves the comfort and safety of elevator use through intelligent control and humanized design.

[0045] Among them, the primary filter (G1 or G4 level) is used to filter out larger particles, such as dust, hair, dandruff and some fibers.

[0046] Medium efficiency filter (F5-F9 level): further filters smaller particles, including some pollen, smoke particles, etc.

[0047] High-efficiency filter (HEPA filter, H11-H14 level): can effectively capture fine particles with a diameter of more than 0.3 microns, such as PM2.5, bacteria, viruses, etc.

[0048] Electrostatic dust collection layer / pre-filter layer: uses the principle of electrostatics to absorb tiny particles, reduce the pressure on subsequent filters, and extend the life of high-efficiency filters.

[0049] The parts not described in detail in this application are prior art, so this application does not describe them in detail.

[0050] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0051] Although the present invention uses more terms such as elevator car 1, aluminum gusset ceiling 2, control switch 3, external air purification component 4, air cooler component 5, second air filter layer component 6, installation position 11, air outlet panel 12, ventilation duct 41, first air filter layer component 42, LED light board 51, air outlet 52, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the present application; interpreting them as any additional restrictions is contrary to the spirit of the present application.

[0052] The present application is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of this application. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present application.
