Description

Technical Field

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

[0002] With the acceleration of urbanization, elevators have become an indispensable vertical transportation tool in people's daily lives. However, as a relatively enclosed space with a large flow of people and a complex mix of individuals, elevators have poor air circulation, which can easily lead to the growth and spread of viruses, bacteria and other microorganisms, posing a potential threat to people's health.

[0003] The installation of filters in the pre-filter system of existing air purification devices is relatively complicated, and replacement requires a lot of time. Moreover, after installation, the filter may not be centered or aligned with the air inlet, and the filter may not fit tightly against the air inlet, often leaving gaps. These gaps allow impurities in the air to directly enter the filtration system, greatly reducing the filtration efficiency of the pre-filter system.

[0004] The existing patent (publication number: CN211977102U) discloses an air disinfection and sterilization device for elevators, including a top cover, an outer shell at the bottom of the top cover, a primary filter module inside the outer shell, a photocatalytic filter on the right side of the primary filter module, an ultraviolet lamp on the right side of the photocatalytic filter, a fan on the right side of the ultraviolet lamp, and a circuit board on the right side of the fan. The primary filter module includes a filter shell, an upper filter cotton module inside the filter shell, and a fixing frame. The upper filter cotton is fixed inside the fixing frame.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An elevator ventilation and disinfection device includes a ventilation and disinfection device body 1, an air inlet 2 and an air outlet 3. The top of the ventilation and disinfection device body 1 is provided with an installation plate 4. The inside of the installation plate 4 is provided with a fixing component 5 that works with the ventilation and disinfection device body 1. A filter component 6 is provided at the air inlet 2 at the bottom of the ventilation and disinfection device body 1.

[0029] The fixing component 5 includes a nut head 501, which is located on the left side of the mounting plate 4. A bidirectional screw 502 is fixedly connected to the right side of the nut head 501. The right side of the bidirectional screw 502 extends through to the right side of the mounting plate 4. The side of the surface of the bidirectional screw 502 closest to the inner wall of the mounting plate 4 is rotatably connected to the inner wall of the mounting plate 4 via a bearing. Both sides of the surface of the bidirectional screw 502 are threadedly connected to internal thread blocks 503. Connecting strips 504 are fixedly connected to the bottom of the two internal thread blocks 503. Fixing claws 505 are fixedly connected to the front and rear sides of the bottom of the two connecting strips 504.

[0030] In this embodiment: by setting up a ventilation and disinfection equipment body 1, an air inlet 2, an air outlet 3, a mounting plate 4, a fixing component 5, and a filter component 6, during use, the ventilation and disinfection equipment body 1 can draw in air from the elevator through the air inlet 2, then purify and disinfect the air through its internal purification and disinfection structure, and then discharge it into the elevator through the air outlet 3, thus achieving the effect of ventilation and disinfection in the elevator. The mounting plate 4 provides a supporting foundation for the installation of the ventilation and disinfection equipment body 1. The fixing component 5 can install and fix the ventilation and disinfection equipment body 1, and the installation and fixing method is relatively simple. It is also convenient to disassemble and assemble the ventilation and disinfection equipment body 1 during later inspection and maintenance, which brings convenience to the operators. The filter component 6 can pre-filter the air entering the ventilation and disinfection equipment body 1, intercepting impurities, thus making it easier to clean the impurities later.

[0031] Specifically, such as Figure 1 , Figure 4As shown, the filter assembly 6 includes a fixed frame 601, which is fixedly connected to the air inlet 2 at the bottom of the air exchange and disinfection equipment body 1. A filter screen 602 is provided at the bottom of the fixed frame 601, and the right side of the filter screen 602 is rotatably connected to the right side of the fixed frame 601 through a torsion spring shaft.

[0032] Specifically, such as Figure 1 , Figure 4 As shown, a U-shaped sealing gasket 603 is fixedly connected to the top of the filter screen plate 602, and the top of the U-shaped sealing gasket 603 is in close contact with the bottom of the fixed frame 601.

[0033] Specifically, such as Figure 1 , Figure 4 As shown, an opening and closing handle 604 is fixedly connected to the left side of the filter screen 602. The top and bottom of the opening and closing handle 604 are provided with anti-slip textures.

[0034] In this embodiment: by setting a fixed frame 601, a filter screen 602, a U-shaped sealing gasket 603, and an opening and closing handle 604, during use, the fixed frame 601 provides a supporting foundation for the filter screen 602. The filter screen 602 can pre-filter the air entering the air exchange and disinfection equipment body 1, intercepting impurities. When cleaning impurities on the filter screen 602 later, the filter screen 602 can be opened by opening and closing the handle 604 to clean the inside and outside of the filter screen 602, which is quite convenient. After cleaning, the opening and closing handle 604 is released, and then the filter screen 602 will automatically reset and close under the action of the torsion spring shaft. The U-shaped sealing gasket 603 can seal the connection between the filter screen 602 and the fixed frame 601 to prevent air from entering from the connection between the filter screen 602 and the fixed frame 601.

[0035] Specifically, such as Figure 1 , Figure 2 As shown, the mounting plate 4 has a limiting groove 7 inside that works with the internal thread block 503. The side of the internal thread block 503 that is close to the inner wall of the limiting groove 7 is slidably connected to the inner wall of the limiting groove 7.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a rubber pad 8 is fixedly connected to the side of the fixed clamp 505 near the air exchange and disinfection equipment body 1, and the side of the rubber pad 8 near the air exchange and disinfection equipment body 1 is in close contact with the air exchange and disinfection equipment body 1.

[0037] In this embodiment: by setting the limiting groove 7, the internal thread block 503 can be guided and limited, so that the internal thread block 503 can move stably left and right under the action of the thread when the twin screws rotate. By setting the rubber pad 8, the fixing claw 505 can be prevented from causing clamping damage to the air exchange and disinfection equipment body 1, and the clamping and fixing effect of the fixing claw 505 on the air exchange and disinfection equipment body 1 can be increased.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, positioning strips 9, which are used in conjunction with the main body 1 of the ventilation and disinfection equipment, are fixedly connected to the front and rear sides of the bottom of the mounting plate 4. The shape of the positioning strips 9 matches the shape of the top structure of the main body 1 of the ventilation and disinfection equipment.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, mounting blocks 10 are fixedly connected to the front and rear sides of both sides of the mounting plate 4, and mounting holes 11 are provided at the bottom of the mounting blocks 10.

[0040] In this embodiment: by setting the positioning strip 9, the installation position of the air exchange and disinfection equipment body 1 can be initially positioned. By setting the mounting block 10 and the mounting hole 11, the mounting plate 4 can be installed and fixed to the elevator using bolts.

[0041] Working principle: In use, the mounting plate 4 is first fixed in a suitable position inside the elevator using bolts through the mounting block 10 and mounting through hole 11. When installing the ventilation and disinfection equipment body 1, it can be placed between the two positioning strips 9. The two positioning strips 9 can initially position the ventilation and disinfection equipment body 1. Then, by turning the nut head 501, the nut head 501 drives the bidirectional screw 502 to rotate. Through the rotation of the bidirectional screw 502, the two internal threaded blocks 503 will slide in opposite directions in the limiting groove 7 under the action of the threads. The two internal threaded blocks 503 will respectively drive the two The two connecting bars 504 move in opposite directions, causing the two sets of fixing claws 505 to move closer to the air exchange and disinfection equipment body 1 until the rubber pads 8 on the inner side of the fixing claws 505 are tightly fitted to the air exchange and disinfection equipment body 1. This allows for stable clamping and fixing of the air exchange and disinfection equipment body 1 by the four fixing claws 505, thus completing the installation of the air exchange and disinfection equipment body 1. The operation is relatively convenient. When disassembly, inspection, and maintenance of the air exchange and disinfection equipment body 1 are required later, the nut head 501 can be twisted in the reverse direction, causing the nut head 501 to drive the bidirectional screw 502 to rotate in the opposite direction. Reverse rotation causes the two internally threaded blocks 503 to slide simultaneously in opposite directions within the limiting groove 7 under the action of the threads. The two internally threaded blocks 503 then drive the two connecting bars 504 to move in opposite directions, which in turn drives the two sets of fixing claws 505 away from the air exchange and disinfection equipment body 1. This releases the fixation on the air exchange and disinfection equipment body 1, allowing it to be removed from between the two positioning bars 9 for disassembly. Disassembly and assembly are convenient, providing ease of use for operators. Furthermore, when performing air exchange and disinfection inside the elevator, the air exchange and disinfection equipment body 1 can draw in air from the elevator through the air inlet 2. Then, the air is purified and disinfected through its internal purification and disinfection structure, and then discharged into the elevator through the air outlet 3, thus achieving the effect of air exchange and disinfection in the elevator. Before the air enters the air inlet 2, the air can be pre-filtered by the filter plate 602 to intercept impurities. When cleaning the impurities on the filter plate 602 later, the filter plate 602 can be opened by the opening and closing handle 604 to clean the inside and outside of the filter plate 602, which is quite convenient. After cleaning, the opening and closing handle 604 is released, and the filter plate 602 will automatically reset and close under the action of the torsion spring shaft.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
