Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an air curtain machine. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings, and is a fixed lifting device that serves specified floors. At the same time, a vertical lift has a car that runs between at least two rows of vertical rigid guide rails. During the operation of the elevator, the environment inside the elevator is closed, and there will be floating dust in the air that affects the respiratory health of the passengers, so an air curtain machine is needed to purify the air.

[0003] According to a wind curtain machine disclosed in patent search publication number CN218379832U, its beneficial effects are: it can collect oil and dust through the filter plate, and rely on the gravity of the oil to make the oil drip into the oil collection box, without the need to disassemble the entire wind curtain machine, which is simple and convenient.

[0004] When the air curtain is used to filter the internal environment of the elevator, the position of the PVC filter installed inside the air curtain is fixed, and while its position is fixed, it will also reduce the filterable area, thereby affecting the efficiency of filtering in the elevator. Utility Model Content

[0005] The utility model provides an air curtain machine to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wind curtain machine comprises a wind curtain machine shell, wherein a top dust suction grid is inserted into the upper end of the wind curtain machine shell by opening a through hole, dust suction motors are fixedly connected to both sides of the inner bottom wall of the wind curtain machine shell, the output end of the dust suction motor is spline-connected to a multi-way exhaust duct, the surface of the multi-way exhaust duct is fixedly connected to a support partition, both sides and the middle of the upper end of the support partition are fixedly connected to a support top plate, one side of the support top plate is spline-connected to an installation card limit unit through a rotating motor, and the output end of the installation card limit unit is spline-connected to a PVC porous filter.

[0008] As a further improvement of the technical solution: a supporting buckle is fixedly connected to the middle of the upper end of the top dust suction grid plate, and mounting top blocks are fixedly connected to both side surfaces of the air curtain housing.

[0009] As a further improvement of the technical solution: both sides of the lower end of the air curtain housing are fixedly connected with limiting slot blocks, and the inner wall of the limiting slot block is slidably connected with a placement base.

[0010] As a further improvement of the technical solution: ventilation grille plates are fixedly installed on both sides of the front side of the air curtain housing by means of bolts, and the number of the dust extraction motors is several, and the several dust extraction motors form a group of two.

[0011] As a further improvement of the technical solution: the installation clamping limit unit comprises a main body connecting top block, and the inner bottom wall of the main body connecting top block is fixedly connected with a supporting clamp block.

[0012] As a further improvement of the present technical solution: the upper and lower ends of the main connecting top block are fixedly connected with an L-shaped connecting top block, the inner bottom wall of the L-shaped connecting top block is fixedly connected with a limiting support shaft, and the surface of the limiting support shaft is slidably connected with a rubber limiting rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The driving motor drives the PVC porous filter to rotate, and allows the sucked dust to adhere to the rotating PVC porous filter. When the air curtain stops operating, the rubber limit lever is buckled and driven to slide correspondingly on the L-shaped connecting top block and the limit support shaft, thereby releasing the fixed restriction on the PVC porous filter and removing it along the front. While the PVC porous filter is easy to disassemble, the dust adhesion and filtration area will be increased during the rotation process, thereby increasing the dust filtration effect.

[0027] See also Figures 1 to 5In the embodiment of the utility model, an air curtain machine comprises an air curtain machine housing 1, a top dust suction grid plate 2 is inserted into the upper end of the air curtain machine housing 1 through a through hole, dust extraction motors 3 are fixedly connected to both sides of the inner bottom wall of the air curtain machine housing 1, the output end of the dust extraction motor 3 is splinedly connected to a multi-way exhaust pipe 4, the surface of the multi-way exhaust pipe 4 is fixedly connected to a support partition 5, both sides and the middle of the upper end of the support partition 5 are fixedly connected to a support top plate 6, one side of the support top plate 6 is splinedly connected to an installation card limit unit 8 through a rotating motor 7, and the output end of the installation card limit unit 8 is splinedly connected to P The VC porous filter 9 drives the rotating motor 7 to rotate the PVC porous filter 9, and allows the sucked dust to adhere to the rotating PVC porous filter 9. When the air curtain stops operating, the rubber limit card rod 805 is buckled and driven to slide correspondingly on the L-shaped connecting top block 803 and the limit support shaft 804, thereby releasing the fixed restriction on the PVC porous filter 9 and removing it along the front. While the disassembly is convenient, the PVC porous filter 9 will also increase the dust adhesion and filtration area during the rotation process, thereby increasing the dust filtration effect.

[0028] See also Figures 1-2 A support buckle 10 is fixedly connected to the middle of the upper end of the top dust collection grid 2, and mounting top blocks 11 are fixedly connected to both sides of the air curtain housing 1. The support buckle 10 assists in opening the top dust collection grid 2 and facilitates the subsequent cleaning operation of the PVC porous filter screen 9.

[0029] See also Figures 1-2 Both sides of the lower end of the air curtain housing 1 are fixedly connected with a limiting slot block 12, and the inner wall of the limiting slot block 12 is slidably connected with a placement base 13. When preparing to install the air curtain, the placement base 13 is used as a protective pad at the bottom of the air curtain.

The surface of the limiting support shaft 804 is slidably connected with a rubber limiting clamping rod 805. When the rubber limiting clamping rod 805 slides on the limiting support shaft 804, the sliding direction is limited, so that the rubber limiting clamping rod 805 can avoid being unable to be normally plugged into the socket opened on the PVC porous filter screen 9 during the sliding process.

[0033] The working principle of the utility model is:

[0034] Start the rotating motor 7 to drive the PVC porous filter 9 to rotate, and at the same time drive the dust extraction motor 3 to draw dust into the air curtain housing 1 through the multi-way exhaust duct 4, and the dust is filtered over a large area by the rotating PVC porous filter 9. Then stop the air curtain and buckle the support buckle 10 to remove the ventilation grille plate 14 from the air curtain housing 1, and buckle the rubber limit card rod 805 to slide upward or downward from the limit support shaft 804, so that the rubber limit card rod 805 releases the plug-in state of the PVC porous filter 9, and the PVC porous filter 9 is removed and cleaned.
