Description

Technical Field

[0001] This utility model relates to the field of passenger elevator technology, specifically to an ultra-quiet passenger elevator with a soundproof cabin. Background Technology

[0002] Passenger elevators are vertical lifting devices primarily used for transporting people. Driven by an electric motor, the car moves up and down between guide rails. Widely used in residential buildings, office buildings, and other similar structures, they are the most prevalent type of elevator in modern architecture. Their design emphasizes safety, comfort, and efficiency, and they are equipped with multiple protection systems to ensure passenger safety. However, current passenger elevators still have the following shortcomings:

[0003] For example, patent document CN213475115U discloses an anti-pinch passenger elevator. This anti-pinch passenger elevator ensures that the first and second elevator doors close only when the passenger is fully inside the elevator by prioritizing the movement of the anti-pinch bar and controlling the movement of the moving part through a sensor device inside the anti-pinch bar. This avoids the situation where the first and second elevator doors close when the passenger is in the anti-pinch bar area, preventing the passenger or passenger's belongings from being trapped. However, its sound insulation effect is poor, which can lead to noise interference, affect passenger comfort, and may also compromise privacy. Utility Model Content

The built-in soundproofing cotton is disposed inside the car floor.

[0006] Furthermore, the upper surface of the car floor is provided with an EPDM shock-absorbing pad, and the thickness of the EPDM shock-absorbing pad is 3 cm.

[0007] Furthermore, a hollow sound insulation cavity is provided inside the fixed side frame, and the hollow sound insulation cavity is filled with polyurethane foam.

[0008] Furthermore, the fixed side frame is an integrated structure, and sound-insulating damping felt is provided on the inner and outer sides of the fixed side frame.

[0009] Furthermore, both the exhaust port and the air inlet are equipped with ventilation silencers, and two sets of ventilation silencers are provided. The inner surface of the elevator door is provided with a double-layer sealing strip.

[0010] Furthermore, the car roof panel is an integrated structure, and a lighting lamp is provided on the lower side of the car roof panel, while an elevator button is provided on the right end of the inner surface of the fixed front frame.

[0011] Furthermore, a circulation component for circulating air is provided inside the exhaust port, and the circulation component includes a vibration damping exhaust fan, a dustproof net and a limiting frame. The vibration damping exhaust fan is located inside the exhaust port, and dustproof nets are installed above and below the vibration damping exhaust fan. The limiting frame is engaged and connected inside the air inlet.

[0012] Furthermore, the circulation assembly also includes a mounting frame, mounting bolts, a filter screen, an activated carbon filter screen, a photocatalytic filter screen, and a catalytic UV lamp.

A photocatalytic filter screen is installed below the activated carbon filter screen, and a catalytic UV lamp is provided on the lower inner side of the limiting frame.

[0013] This utility model provides an ultra-quiet passenger elevator with a soundproof cabin, which has the following advantages:

[0014] 1. This utility model incorporates a sound insulation component, which includes built-in sound insulation cotton, EPDM damping pads, a hollow sound insulation cavity, sound insulation damping felt, a vent silencer, and double-layer sealing strips. In use, the double-layer hollow structure is employed. The hollow sound insulation cavity is filled with polyurethane foam, giving the fixed side frame sound insulation, waterproofing, and flame retardant properties. The sound insulation damping felt reduces airborne sound transmission, the built-in sound insulation cotton absorbs airborne noise, and the EPDM damping pads block solid-borne vibration. The combined effect of these two components covers a wider frequency range of noise. The vent silencer silences the exhaust and intake vents, and the double-layer sealing strips on the elevator door surface improve sealing and sound insulation, further enhancing sound insulation performance. Thus, this device employs a multi-layered noise reduction and sound insulation structure to achieve effective sound insulation inside the elevator car.

[0015] 2. This utility model incorporates a circulation component, which includes a vibration-damping exhaust fan, a dust filter, and a limiting frame. The circulation component also includes a mounting frame, mounting bolts, a filter, an activated carbon filter, a photocatalytic filter, and a catalytic UV lamp. In use, the limiting frame is installed at the air inlet by engaging with the inner side of the air inlet. The mounting bolts are then threaded onto the mounting frame surface for further installation and fixation. The vibration-damping exhaust fan is then activated, expelling internal air through the exhaust port. The dust filter prevents dust and other impurities from entering. The air is fed into the vibration damping exhaust fan, while outside air enters through the air inlet. Dust and other impurities are filtered out by the filter screen, and the activated carbon filter can adsorb smoke, food residue odors, etc. in the enclosed environment of the elevator, improving air quality. Through the synergistic effect of the photocatalytic filter and the catalytic UV lamp, organic pollutants such as formaldehyde and benzene can be decomposed into CO2 and H2O. At the same time, it causes oxidative damage to the cell structure of bacteria, viruses and other microorganisms, so that the device can realize the air circulation inside the elevator, ensure sufficient oxygen supply, and effectively remove internal odors.

EPDM damping pad 802 with a thickness of 3 cm is installed on the upper surface of the car floor 1. A hollow sound insulation cavity 803 is opened inside the fixed side frame 2 and filled with polyurethane foam. The fixed side frame 2 is an integrated structure and sound insulation damping felt 804 is installed on the inner and outer sides of the fixed side frame 2. Ventilation silencers 805 are installed on the upper side of the exhaust port 6 and the air inlet 7. Two sets of ventilation silencers 805 are installed. Double-layer sealing strip 806 is installed on the inner surface of the elevator door 5.

[0023] The specific operation is as follows: When in use, the fixed side frame 2 adopts a double-layer hollow structure.

The sound insulation damping felt 804 can reduce the air transmission rate, the built-in sound insulation cotton 801 can absorb air noise, and the EPDM shock absorption pad 802 can block solid vibration transmission. The combination of the two can cover a wider range of noise. The ventilation silencer 805 can silence the exhaust port 6 and the air inlet 7.
