Description

Technical Field

[0001] This utility model relates to the field of elevator air purification and ventilation technology, and in particular to an air purification and ventilation device. Background Technology

[0002] An elevator is a transportation device that serves several specific floors within a building. Its car runs 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. There are various types of elevators, including but not limited to passenger elevators, freight elevators, medical elevators, dumbwaiters, sightseeing elevators, vehicle elevators, ship elevators, and construction elevators. Each type of elevator has its specific purpose and design.

[0003] The published patent document with publication number CN222459708U discloses an elevator purification and ventilation device, including a box body, a base plate fixedly installed at the bottom of the box body, a connecting main pipe for air transportation fixedly installed inside the base plate, and multiple sets of first connecting branch pipes connected to the connecting main pipe.

[0004] However, the aforementioned existing technology has its shortcomings in use. It does not have the function of heating the air. When used in winter, the air blown downwards through the exhaust hood is relatively cold. This cold air will blow directly onto the people riding the elevator, which can easily cause discomfort to the people riding the elevator. Therefore, we propose an air purification and ventilation device. Utility Model Content

[0030] Example 2

[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution. Preferably, the heating mechanism 1 includes a heating hollow plate 101, which is fixedly connected to the upper end face of the compartment 3. A serpentine coil 103 is provided inside the heating hollow plate 101. Both ends of the serpentine coil 103 penetrate the heating hollow plate 101 and are fixedly connected to the penetration portion.

[0032] In this embodiment, the heating tube 104 can heat the interior of the heating hollow box, thereby heating the air. The serpentine coil 103 can prolong the time that the air stays inside the heating hollow box, thereby improving the heating effect of the air.

[0033] Example 3

[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution. Preferably, the air outlet mechanism 7 includes an air outlet cylinder 702. The upper end of the air outlet cylinder 702 is fixedly connected to the upper inner surface of the chamber 3. The lower end of the air outlet cylinder 702 is fixedly connected to an air outlet hood 704 communicating with the interior of the air outlet cylinder 702. A protective net 705 is fixedly connected to the lower inner end of the air outlet hood 704. A connecting pipe 701 communicating with the interior of the air outlet cylinder 702 is fixedly connected to the upper surface of the air outlet cylinder 702. The connecting pipe 701 penetrates the chamber 3 and is fixedly connected to the penetration portion. The upper end is fixedly connected to one end of the air supply pipe 4. A cleaning port 703 is provided on the front side of the air outlet 702. A sealing plug plate 710 is installed inside the cleaning port 703.

The air is then discharged through the air outlet hood 704 and the protective net 705. By disassembling the disassembly plate 709 and separating the sealing plug 710 from the cleaning port 703, the filter screen 707 and the activated carbon adsorption plate 708 can be removed for cleaning or replacement.

[0036] The specific working principle and usage method of this utility model are as follows:

[0037] This utility model provides an air purification and ventilation device, such as Figure 1-4 As shown, when used in winter, the heating tube 104 and air pump 6 are activated by the controller 8. The activation of the air pump 6 allows the air inside the compartment 3 to be pumped into the heated hollow plate 101 through the hollow bottom plate 9, air inlet 901 and exhaust pipe 2. The air flows through the serpentine coil 103 inside the heated hollow plate 101, which increases the time the air stays inside the heated hollow plate 101 and improves the heating effect. Then the heating tube 104 heats the inside of the heated hollow plate 101, thereby heating the air. The heated air is then pumped into the air outlet 702 through the air supply pipe 4 and connecting pipe 701. The air outlet 702 filters dust from the air through the filter plate 707 and purifies the air through the activated carbon adsorption plate 708. Finally, the heated and purified air is discharged through the air outlet hood 704 and protective net 705, thus preventing the cold air from blowing directly on people riding the elevator in winter and causing discomfort. Subsequently, the filter screen plate 707 and activated carbon adsorption plate 708 can be removed, cleaned, or replaced by disassembling the disassembly plate 709 to separate the sealing plug plate 710 from the cleaning port 703.
