Description

Technical Field

[0001] This utility model relates to the field of ceiling technology, specifically to an elevator ceiling. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, also known as a vertical elevator. Vertical elevators are equipped with a box-shaped cabin and are used in multi-story buildings to transport people or goods. There are also escalator elevators, where steps are mounted on a continuously running track; these are commonly known as automatic elevators, also called escalators, pedestrian elevators, or handrails. An elevator is a fixed lifting device serving designated floors, running between two vertical rigid guide rails. Elevators with a car have a car size and structure designed to facilitate passenger entry and exit or the loading and unloading of goods.

[0003] Existing elevator ceiling technology, such as the multi-functional elevator ceiling disclosed in Chinese Utility Model Publication No. CN213085143U, includes an elevator ceiling with a ventilation opening at the upper end. A dustproof net is provided at the upper end of the ventilation opening. A motor is fixedly connected inside the ventilation opening via a bracket. A fan blade and a scraper are fixedly connected to the upper end of the motor's output shaft.

[0004] The aforementioned patent uses a fan to deliver air and a scraper to remove dust from the filter screen. However, this can easily cause dust to enter the elevator, and since it does not have a cooling device, the ventilation and heat dissipation effect is poor as it relies solely on the fan. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an elevator ceiling that can effectively solve the problems of dust entering the elevator and poor heat dissipation in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an elevator ceiling, including a ceiling body. A mounting box is fixedly connected to the upper part of the ceiling body. A top cover is installed on the upper part of the mounting box. A motor is installed on the top cover. A main shaft is driven to the lower end of the motor's output shaft. A fan blade is fixedly connected to the main shaft. A first gear is fixedly connected to the lower end of the main shaft. A support frame is fixedly connected to the inner top of the ceiling body. A second gear is connected to the support frame via a rotating shaft. A first bevel gear is fixedly connected to the second gear via the rotating shaft. An installation shaft is rotatably connected to the support frame. A second bevel gear is fixedly connected to the installation shaft. Incomplete gears are fixedly connected to both ends of the installation shaft. Sliding toothed plates are provided on both sides of the inner side of the installation shaft. A connecting plate is fixedly connected to the upper part of the sliding toothed plates. A scraper is fixedly connected to the connecting plate. A cooling device is installed on the ceiling body. A heat-conducting bend is fixedly connected to the cooling device. Several aluminum heat sinks are fixedly connected to the heat-conducting bend. A guide plate is driven to the sliding toothed plates.

[0008] Furthermore, a mounting frame is fixedly connected to the lower part of the ceiling body, and a lighting lamp is installed on the mounting frame. The air guide plate is connected to the mounting frame through a rotating shaft.

[0009] Furthermore, a strip groove is provided on one side of the sliding toothed plate, and an insertion rod is fixedly connected to the end of the sliding toothed plate.

[0010] Furthermore, a sliding groove mechanism is fixedly connected to the inner wall of the ceiling body, and a slider is fixedly connected to one side of the sliding toothed plate.

[0011] Furthermore, the refrigeration device includes a refrigeration element, and the ceiling body has through holes for placing the refrigeration element.

[0012] Furthermore, a finned heat sink is provided on the upper part of the cooling chip, and a fan is installed on the finned heat sink.

[0013] Furthermore, a copper plate is provided at the lower part of the cooling chip, and the end of the cooling chip passes through the copper plate and is welded to it.

[0014] Furthermore, a cotton absorbent layer is fixedly connected to the air guide plate, and a return spring is installed at the rear of the sliding toothed plate.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] This invention employs a dual-mode cooling system combining semiconductor refrigeration and forced air cooling, which significantly improves cooling efficiency compared to traditional single-fan cooling methods, resulting in a more uniform and comfortable temperature inside the car. Furthermore, through a clever gear transmission mechanism, a single motor can simultaneously drive the three functional modules: the fan blades, the cleaning mechanism, and the air guide plate. This not only reduces energy consumption but also simplifies the structure and improves system reliability.

[0017] By combining a scraper with aluminum heat sink fins, an automatic cooling water removal function is achieved. The condensate recovery system uses a cotton absorbent layer to absorb the scraped cooling water, which not only avoids dripping but also further enhances the cooling effect through evaporative cooling. This closed-loop water management system is both environmentally friendly and highly efficient.

[0018] The air deflector's angle adjustment mechanism achieves intelligent airflow control through mechanical linkage, allowing for flexible adjustment of the air delivery angle according to different seasons and usage needs, greatly improving user comfort. The cooling system employs a copper plate heat conduction and aluminum plate heat sink design, ensuring efficient transfer of cooling capacity. Combined with the forced heat dissipation of the finned radiator, a complete heat exchange closed loop is formed. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example: An elevator ceiling, see attached diagram. Figure 1 - Appendix Figure 7 The system includes a ceiling body 4, which is a rectangular box structure used for installation on the top of the elevator car. A mounting box 3 is fixedly connected to the upper part of the ceiling body 4. The interior of the mounting box 3 is used to accommodate the fan blades 9. A top cover 2 is installed on the upper part of the mounting box 3 by screws. A motor 1 is installed on the top cover 2. The lower end of the output shaft of the motor 1 is connected to a main shaft 16. The fan blades 9 are fixedly connected to the main shaft 16, which plays the role of accelerating the internal air circulation.

[0031] A first gear is fixedly connected to the lower end of the main shaft 16. A support frame 10 is fixedly connected to the inner top of the ceiling body 4. A second gear 15 is connected to the support frame 10 through a rotating shaft. The first gear and the second gear 15 mesh. A first bevel gear 17 is fixedly connected to the second gear 15 through a rotating shaft. A mounting shaft 19 is rotatably connected to the support frame 10. A second bevel gear 18 is fixedly connected to the mounting shaft 19. The first bevel gear 17 and the second bevel gear 18 mesh. Therefore, when the motor 1 moves, it can not only drive the fan blade 9 to rotate, but also drive the first gear and the second gear 15 to rotate, which in turn drives the first bevel gear 17 and the second bevel gear 18 to rotate, which in turn drives the mounting shaft 19 and the incomplete gear 11 to rotate.

[0032] Incomplete gears 11 are fixedly connected to both ends of the mounting shaft 19. Sliding toothed plates 13 are provided on both sides inside the mounting shaft 19. A connecting plate 20 is fixedly connected to the upper part of the sliding toothed plate 13. A scraper 21 is fixedly connected to the connecting plate 20. When the incomplete gear 11 rotates, it can drive the sliding toothed plate 13 to move back and forth, and then drive the scraper 21 to move.

[0033] A cooling device 5 is installed on the ceiling body 4. A heat-conducting bend 22 is fixedly connected to the cooling device 5. Several aluminum heat sinks 23 are fixedly connected to the heat-conducting bend 22. When the scraper 21 moves, it can remove the cooling water on the aluminum heat sinks 23. When the cooling water drips onto the air guide plate 8, it is absorbed by the cotton absorbent layer 82. When the fan blade 9 blows towards the aluminum heat sinks 23 and the air guide plate 8, it can cool down the people in the elevator, which is similar to the effect of an air conditioner fan.

[0034] The sliding toothed plate 13 is connected to the air guide plate 8, and a cotton absorbent layer 82 is fixedly connected to the air guide plate 8. The cotton absorbent layer 82 is used to absorb cooling water.

[0035] The lower part of the ceiling body 4 is fixedly connected to the mounting frame 6, and the mounting frame 6 is equipped with a lighting lamp 7. The air guide plate 8 is connected to the mounting frame 6 through a rotating shaft, so the air guide plate 8 can rotate.

[0036] A strip groove 131 is provided on one side of the sliding toothed plate 13, and an insertion rod 81 is fixedly connected to the end of the sliding toothed plate 13. The insertion rod 81 is inserted into the inside of the strip groove 131. Therefore, when the sliding toothed plate 13 moves back and forth, it can drive the air guide plate 8 to rotate and change the air direction.

[0037] The inner wall of the ceiling body 4 is fixedly connected to a sliding groove mechanism 12, and a slider 14 is fixedly connected to one side of the sliding tooth plate 13. The slider 14 is embedded in the interior of the sliding groove mechanism 12, so that it moves in a straight line.

[0038] The cooling device 5 includes a cooling chip 52. The ceiling body 4 has a through hole for placing the cooling chip 52. When the cooling chip 52 is powered on, the lower end cools and the upper end dissipates heat.

[0039] The upper part of the cooling chip 52 is provided with a finned heat sink 53, and a fan 54 is installed on the finned heat sink 53 to dissipate heat from the hot end.

[0040] The lower part of the cooling chip 52 is provided with a copper plate 51. The end of the cooling chip 52 passes through the copper plate 51 and is welded to it. The copper plate 51 can transfer cold energy to the aluminum heat sink 23.

[0041] A return spring 24 is installed at the rear of the sliding toothed plate 13. One end of the return spring 24 is connected to the ceiling body 4, which serves to reset the position of the sliding toothed plate 13.

[0042] Working principle: Motor 1 serves as the core power source, directly driving the fan blades 9 to rotate at high speed via the main shaft 16, forming a forced airflow circulation inside the ceiling body 4. During this process, the airflow first flows through the aluminum heat sink 23 pre-cooled by the refrigeration system, and after completing heat exchange, it is then evenly delivered into the car through the multi-angle adjustable air guide plate 8 to achieve directional air delivery.

[0043] To extend a single power source into a multi-functional mechanism, the system employs a four-stage gear transmission design: the first gear at the end of the main shaft 16 drives the second gear 15, and then the transmission direction is reversed through the orthogonal meshing of the first bevel gear 17 and the second bevel gear 18. Finally, the mounting shaft 19 drives the incomplete gears 11 at both ends to rotate synchronously. This precision transmission chain ensures that the motor 1 can provide power for subsequent wiping and airflow adjustment while driving the fan blades 9.

[0044] The periodic rotation of the incomplete gear 11 drives the sliding toothed plate 13 to reciprocate along the sliding groove mechanism 12 via rack and pinion meshing. The scraper 21 on the connecting plate 20 then scrapes the surface of the aluminum heat sink 23, removing accumulated condensate. The return spring 24, through its elastic return function, ensures the stroke accuracy of the sliding toothed plate 13 and prevents mechanical jamming. The removed condensate flows along the surface of the air guide plate 8 and is efficiently absorbed by the cotton absorbent layer 82, preventing dripping and enhancing the cooling effect through evaporation.

[0045] The cooling element 52 serves as the core cooling unit. Its cold end is tightly connected to the heat-conducting bend 22 via a copper plate 51, efficiently transferring cold energy to the aluminum heat sink 23. The hot end is cooled by the finned heat sink 53 in conjunction with the fan 54, forming a complete closed-loop heat exchange system. Under the airflow of the fan blades 9, the aluminum heat sink 23 releases cold energy into the air, achieving an active cooling effect similar to that of an air conditioning fan.

[0046] The reciprocating motion of the sliding toothed plate 13 is converted into the dynamic deflection of the air guide plate 8 through the mechanical linkage between the strip groove 131 and the insertion rod 81. This design allows the airflow direction to be adjusted in real time according to needs, such as direct downward airflow to enhance cooling in summer and horizontal airflow to avoid direct cold airflow in winter. The air guide plate 8 is hinged to the mounting frame 6 via a rotating shaft to ensure smooth and low-noise rotation.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
