Description

Technical Field

[0001] The utility model relates to the technical field of seats, and in particular to a personalized air supply device embedded in a seat armrest. Background Art

[0002] In the design of large public places such as sports venues, the issue of ventilation and cooling for the audience must be considered. For example, in existing sports stadiums, cooling equipment (such as air conditioners) are installed on the top. Due to the long distance from the ground, it is difficult to cool the audience; for example, the outdoor space of an outdoor football field is not enclosed, and ordinary cooling equipment cannot cool the audience, causing the audience to suffer from hot air outdoors, which may even cause heat stroke and life-threatening situations in severe cases; for another example, the space in ordinary sports stadiums is large, and in order to achieve a comfortable temperature in the stadium, the cooling device must be turned on before opening, so that the indoor temperature gradually drops. In addition, there are no spectators in some areas of the venue, but in order to achieve a cooling effect, the stadium is still forced to turn on the cooling device, resulting in a great waste of energy;

[0003] In this regard, the Chinese patent publication number CN201798319U discloses "a ventilated seat, comprising a seat and a seat back supported by the seat, wherein the seat back is provided with at least one air duct, wherein the air inlet is provided below the seat back and communicates with the air supply outlet of an external air supply device, and the air outlet is provided behind the seat back; the wind direction adjustment device comprises at least one air guide plate, and the air guide plate can at least rotate laterally around the air outlet";

[0004] This patent uses an external air supply device to introduce the low-temperature air into the "air duct" in the "chair back", and then blows the low-temperature air to the audience behind the seats through the "air outlet" behind the "chair back", thereby cooling the outdoor audience; this structure has obvious technical defects; first, the air supply "air outlet" is behind the "chair back", which prevents the audience in the front row from being blown by the wind; second, due to the certain interval between the front and rear rows of seats, the distance from the "air outlet" of the front row "chair back" to the audience in the back row is longer, so that the cold air blown out of the "air outlet" will be greatly weakened when it reaches the audience in the back row, which results in a poor cooling effect on the audience. Utility Model Content

[0005] The utility model provides a personalized air supply device embedded in a seat armrest, which solves the problem of poor cooling effect for spectators in the prior art.

[0006] The technical solution of the utility model is as follows: a personalized air supply device embedded in a seat armrest, comprising two support columns, armrest air supply assemblies are installed on the top of the two support columns, the armrest air supply assembly comprises a mounting seat, the mounting seat is fixedly installed on the support column, a rotating block is rotatably installed on the inner side of the mounting seat, a connecting piece is installed on the end of the rotating block away from the mounting seat, an end of the connecting piece away from the rotating block is connected to an armrest tube, a sleeve is fixedly installed on the bottom end of the support column, an air supply hose is installed on the inner side of the sleeve, the air supply hose passes through the support column, the rotating block and the connecting piece, and is connected to the inside of the armrest tube.

[0007] Preferably, a plurality of air outlet holes are provided on the handrail tube, and the plurality of air outlet holes are evenly distributed on the handrail tube.

[0008] Preferably, the inlet end of the air supply hose is connected to a corresponding air supply device.

[0009] Preferably, the connecting member includes an adapter seat, the adapter seat is fixedly connected to the rotating block, a mounting groove is opened on the inner side of the rotating block, a rotating ring is rotatably installed on the inner side of the mounting groove, and one side of the rotating ring is fixedly connected to the handrail tube.

[0010] Preferably, a sealing ring is provided on one side of the rotating ring, and the sealing ring is sleeved on the handrail tube and in contact with the rotating ring.

[0011] Preferably, a positioning member is installed on the outer side of the mounting seat, and the positioning member includes a rotating plate, and the rotating plate is coaxially fixedly connected to the rotating block.

[0012] Preferably, a positioning rod is slidably mounted on the outer edge of the rotating plate, the positioning rod passes through the rotating plate, and a pull block is fixedly mounted on one end of the positioning rod.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The cold air from the air supply equipment can be introduced into the two handrail tubes through the air supply hose, and then discharged from the air outlet holes on the handrail tubes and blown to the audience. Since the air outlet holes on the two handrail tubes are closer to the audience, the audience can feel better cool. The cold air from the two handrail tubes forms air convection, which can quickly cool down the audience to avoid discomfort.

[0018] 2. When adjusting the angle of the handrail tube, the pull block is pulled outward to make the positioning rod slide outward, which causes the positioning rod to disengage from the positioning hole. At this time, the spring is squeezed by the limit block to accumulate elastic potential energy. Then the handrail tube can be rotated in the vertical direction to adjust the angle. When it is adjusted to the target angle, the pull block is released. At this time, the spring releases the potential energy, so that the positioning rod cooperates with the corresponding positioning hole. This can keep the rotating plate fixed, and then keep the rotating block fixed, so that the handrail tube can stably maintain the target angle. The whole process is simple to operate, and the installation angle of the handrail tube can be adjusted independently, thereby meeting the requirements of different groups of people for the angle of the handrail tube.
