Description

Technical Field

[0001] The utility model relates to the technical field of seat ventilation, and particularly relates to an air supply structure for seats in public buildings. Background Art

[0002] With the continuous improvement of the society's requirements for the quality of public environments, especially the emphasis on public health and air quality in the post-epidemic era, public buildings such as large convention centers have an increasingly urgent need for refined management of air circulation and temperature control. Traditional air conditioning systems, although they play a certain role in maintaining the stability of large-space environments, their inherent limitations are insufficient to meet modern complex requirements.

[0003] Specifically, traditional air supply systems often adopt a centralized layout and distribute air through air outlets on the ceiling or side walls. This method is difficult to precisely control the microclimate environment in each independent area. In public buildings with high personnel mobility and diverse activity patterns, this "one-size-fits-all" air supply strategy often leads to overcooling or overheating in some areas, while increasing energy consumption and operating costs.

[0004] Chinese patent document CN214230625U discloses an air supply seat for public places. The utility model relates to an air supply seat for public places and belongs to the technical field of multifunctional seats. It includes a seat, a backrest, and a seat body. The seat and the backrest are arranged on the seat body. The seat is rotatably connected to the seat body, and the backrest is fixedly connected to the seat body. Two connecting blocks are arranged at one end of the seat. Air supply pipes are respectively arranged near both sides inside the seat. A plurality of through holes are arranged at corresponding positions of the air supply pipes on the seat, and the through holes penetrate through the seat and the air supply pipes. Two third connecting pipes and an air inlet pipe are arranged at intervals from top to bottom inside the backrest. The third connecting pipes and the air inlet pipe are connected through a second connecting pipe. The utility model solves the problems such as poor air flow mobility existing in the existing ventilation seats.

[0005] It is pointed out in the prior art that when wet cleaning is carried out under the seat, water will enter the ventilation pipeline and damage the equipment; the noise at the air outlet is large, and the air blows directly at the human body, resulting in poor comfort.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-4 shown in, an air supply structure for a seat in a public building includes a bottom plate 21 fixedly installed on a support surface. An upright column 20 is fixedly arranged on the bottom plate 21. A seat 10 is fixedly installed at the top end of the upright column 20. The upright column 20 is a hollow structure. A plurality of ventilation holes are formed on the side wall of the upright column 20. A ventilation pipe 30 is fixedly penetrated through the upright column 20. The bottom end of the ventilation pipe 30 is connected to a wind source. A wind ball assembly is rotatably sleeved on the top of the ventilation pipe 30. The wind ball assembly includes a sleeve 32 rotatably sleeved on the top of the ventilation pipe 30. A wind ball 31 is fixedly arranged at the top of the sleeve 32. A top plate 33 is fixedly arranged at the top of the wind ball 31. The side wall of the wind ball 31 has an air outlet.

[0027] Figure 2 As shown, several through holes are opened on the column 20 of the present utility model for air outlet. The air outlet is penetrated and extended to the upper part inside the column. The air source sends air through the ventilation pipe 30, which spreads from top to bottom inside the column 20 and then is discharged from the through holes on the column 20, so that the fresh air supply is discharged through the outer circumference of the cylinder. The air outlet surface is wide and the air outlet is gentle; the air outlet of the ventilation pipe 30 is higher than the through holes on the column 20, preventing the cleaning water flow or dust outside the column from entering the ventilation pipeline and ensuring the cleanliness of the equipment;

[0028] Furthermore, the air ball 31 is of a hollow structure. The side wall of the air ball 31 includes several arc-shaped blades arranged in an array, and a ventilation gap is provided between adjacent arc-shaped blades.

[0029] Figure 4 As shown, a rotatable air ball 31 is installed at the top end of the air outlet pipe 30. When the fresh air supply passes through the air ball 31, it flows out from the gap between the arc-shaped blades of the air ball 31, driving the air ball 31 to rotate. The air ball 31 rotates while exhausting air, reducing the noise of the air outlet pipe 30;

[0030] Furthermore, a second support frame 35 is fixedly arranged inside the air ball 31. A connecting rod 38 is vertically fixedly arranged on the second support frame 35. The top end of the connecting rod 38 is fixedly connected to a top plate 33, the bottom end of the connecting rod 38 is fixedly connected to a rotating cylinder 36, the bottom of the rotating cylinder 36 is rotatably sleeved with a support rod 37, the bottom of the support rod 37 is fixedly provided with a first support frame 34, and the end of the first support frame 34 is fixedly connected to the ventilation pipe 30.

[0031] Figure 4 As shown, the second support frame 35 is fixedly connected to the connecting rod 38, the rotating cylinder 36, the sleeve 32 and the air ball 31. The first support frame 34 is fixedly connected to the ventilation pipe 30. The support rod 37 is sleeved inside the rotating cylinder 36. The support rod 37 supports the rotating cylinder 36, the connecting rod 38, the second support frame 35, the air ball 31 and the top plate 33, allowing them to rotate together. A bearing can be installed between the support rod 37 and the rotating cylinder 36 for smoother rotation; the sleeve 32 is sleeved on the outer circumference of the ventilation pipe 30 and rotates to limit the radial direction.

[0032] Furthermore, a sound-absorbing ring 23 is fixedly installed on the upper part of the inner wall of the column 20. The sound-absorbing ring 23 includes a perforated sound-absorbing board and a perforated back board, and a sound-absorbing cloth is installed between the perforated sound-absorbing board and the perforated back board.

[0033] Figure 3 As shown, a sound-absorbing ring 23 is installed on the outer circumference of the air ball 31. The rotating air ball 31 conveys the fresh air supply to the sound-absorbing ring 23 and then flows out through the through holes on the column 20, further reducing the noise generated during the air supply process.

[0034] Furthermore, the perforated sound-absorbing panel is made of gypsum board, the perforated back panel is made of stainless steel, and the sound-absorbing cloth is made of polyester fiber.

[0035] When sound waves strike the surface of the sound-absorbing panel, the sound waves will enter these pores and propagate therein. Inside the pores, the sound waves will rub against the pore walls, causing the sound energy to gradually be converted into heat energy. This energy conversion process effectively reduces the energy of the sound waves, thereby achieving the effect of noise reduction.

[0036] Furthermore, the air vent 31 is made of stainless steel, and the thickness of the arc-shaped blades of the air vent 31 is not less than 3 mm.

[0037] Selecting stainless steel material with a thickness above 3 mm has good hardness, stable chemical properties, is not easily corroded, and is durable.

[0038] Further, the bottom plate 21 and the supporting surface are fixedly connected by expansion bolts.

[0039] During the installation process, first connect the air inlet 39 of the ventilation pipe 30 to the air source, seal and fix it, and then use expansion bolts to fix the bottom plate 21 to the supporting surface. The supporting surface is a concrete floor, and the air source is the branch pipe interface of centralized air supply.

[0040] The present utility model uses the above embodiments to illustrate the technical concept of the present utility model, but the present utility model is not limited to the above embodiments, that is, it does not mean that the present utility model must rely on the above embodiments to be implemented. Those skilled in the art should understand that the relevant improvements to the present utility model all fall within the protection scope and the disclosure scope of the present utility model.
