DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1The utility model provides a technical solution: a ventilation device suitable for an elevator, comprising a device shell 3, an air inlet assembly 2 is provided at the upper right part of the device shell 3, an exhaust port 1 is penetrated through the left part of the top of the device shell 3, an air filter element 4 is provided at the upper right part of the device shell 3, the air inlet assembly 2 is responsible for transporting air through the air filter element 4, the activated carbon filter cotton and the primary filter cotton in the filter element can filter and absorb impurities and dust in the air, reduce the content of particulate matter in the air, and improve the air quality, an air outlet assembly 5 is provided at the lower right part of the device shell 3, and a wind dispersion assembly 6 is provided at the lower end of the air outlet assembly 5, and the air outlet assembly 5 cooperates with the wind dispersion assembly 6 to deliver fresh air that is soft and has no wind feeling.

[0025] See also Figure 2 The air inlet assembly 2 includes an air collecting groove 22, and a plurality of air inlets 23 are fixedly connected to the top of the air collecting groove 22. The air is sent to the air collecting groove 22 through the air intake fan 21 and filtered through the air filter element 4. The middle part of the inner side of each air inlet 23 is rotatably connected to the air intake fan 21. Each group of air inlets 23 is connected in parallel with the air intake fan 21, which can utilize the principles of fluid mechanics to achieve uniform distribution and efficient flow of air. Even if one of the air intake fans 21 fails for various reasons, the entire device can still maintain normal operation, which not only improves the reliability of the equipment, but also greatly reduces the overall downtime risk caused by a single failure.

[0026] A filter element slot is provided at the bottom of the right end of the air collecting slot 22, and the air filter element 4 is inserted into the filter element slot. The filter element slot can facilitate users to replace the air filter element 4 therein. An air outlet component 5 is fixedly connected to the bottom of the air collecting slot 22. The air transported by the air intake fan 21 can be purified as a whole through the air collecting slot 22, thereby increasing the air volume of the air outlet and giving full play to the functionality of the air filter element 4.

[0027] See also Figure 2 The exhaust port 1 includes an exhaust channel 12, an exhaust fan 11 is rotatably connected to the middle of the inner side of the exhaust channel 12, the right end of the exhaust channel 12 is fixedly connected to the left end of the power parallel device 31, and a plurality of pipe openings are opened at the top of the device housing 3 at the relative position between the air inlet 23 and the exhaust channel 12.

[0028] See also Figure 2 and Figure 3The device housing 3 includes a power parallel device 31, and the right side of the power parallel device 31 is fixedly connected to the middle of the left side of the air collecting groove 22. The power parallel device 31 can allow each air intake fan 21 to operate independently, and can also connect the exhaust port 1 and the air intake component 2 to ensure the integrity of the equipment. The front right part of the air collecting groove 22 is in contact with a fixing column 32, and the front end of the fixing column 32 is fixedly connected to the right part of the front end of the inner side of the device housing 3. A fixing groove is opened in the middle of the rear end of the fixing column 32, and a fixing spring 34 is fixedly connected in the fixing groove. A fixing buckle 33 is fixedly connected to the rear end of the fixing spring 34, and the fixing buckle 33 is movably embedded in the right part of the front end of the air filter element 4.

[0029] When the air filter 4 is inserted into the device, the fixing buckle 33 will be squeezed forward, and as the air filter 4 gradually reaches the predetermined position, the fixing spring 34 begins to work. The elastic force of the fixing spring 34 will make the fixing buckle 33 pop out and embed into the slot reserved for the air filter 4, thereby ensuring that the air filter 4 will not be displaced during the use of the device. It can not only ensure the stability and reliability of the air filter 4, but also improve the convenience of the device. When the air filter 4 needs to be replaced, the user only needs to pull it out with a little force, without using any tools or performing complicated operations. This design is not only convenient for users, but also reduces the maintenance cost of the equipment.

[0030] See also Figure 4 The air outlet assembly 5 includes three air outlets 51, the tops of the three air outlets 51 are fixedly connected to the bottom of the air collecting tank 22, and the rear ends of the three air outlets 51 are fixedly connected to the heating pipes 52. The three air outlets 51 can allow the filtered and purified air in the air collecting tank 22 to be discharged evenly, and the temperature of the air can be increased when passing through the heating pipes 52 in the air outlets 51, so that the device can adapt to different environments and increase the use scenarios of the device.

[0031] See also Figure 5 The wind dispersion component 6 includes four support columns 61, and the top ends of the four support columns 61 are movably connected to the adjusting roller 36. The ends of the four support columns 61 away from the adjusting roller 36 are fixedly connected to the wind dispersion plate 62. The top of the wind dispersion plate 62 is penetrated by a plurality of wind dispersion holes. The position of the wind dispersion plate 62 can be adjusted at will by adjusting the roller 36, and the wind dispersion plate 62 can also be allowed to move irregularly with the movement of the elevator to disperse the delivered clean air, thereby subtly purifying the air in the cabin.

[0032] Working principle:

[0033] First of all, in order to keep the air inside the elevator fresh and clean, the air filter 4 needs to be replaced regularly. Just open the reserved slot on the right end of the device and insert a new air filter 5. Then, when the elevator is started and connected to the power parallel device 31, the entire air circulation system starts to operate, and the exhaust fan 11 starts to work to discharge the turbid air in the elevator car. At the same time, the air intake fan 21 also starts to operate to suck fresh air from the outside into the elevator. The sucked air will be uniformly guided to the air collecting tank 22, and then filtered and purified by the previously installed air filter 4. Finally, the heated air will be evenly delivered into the elevator car through the air outlet 51. The wind dispersion plate 62 can disperse the wind and evenly distribute it to every corner of the elevator, so that passengers can feel the fresh and comfortable air without knowing it.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
