[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] See also Figure 1-3The fan 6 is installed in the circular frame 5, and is used to blow air into the heat dissipation holes 4 to blow away the hot air accumulated between the backrest 2 and the back of the person, thereby improving the heat dissipation effect on the back of the person.

[0034] When in use, the person leans on the seat body 1. When the weather is too hot and the back leans on the backrest 2, causing sweating, the fan 6 can be started to suck in air, and then blown to the back of the person through the heat dissipation holes 4, so that the air contacts the back of the person, and the air flow is rolled up to dissipate the heat accumulated between the backrest 2 and the person, thereby improving the heat dissipation effect of the heat dissipation holes 4, cooling the back of the person, and avoiding the back leaning on the backrest 2 for a long time, which often becomes very hot and easily causes sweating of the back, resulting in reduced comfort.

[0035] Reference Figure 1 , an electric adjustment component is provided at the connection between the backrest 2 and the footrest 3 and the seat body 1. The electric adjustment component is a prior art. For example, the car seat can control the angle of the seat backrest 2 and the like through electric adjustment, so I will not go into details. A remote control (not shown in the figure) is provided on the seat body 1. The remote control is wirelessly connected to the electric adjustment component. The person can control the electric adjustment component to adjust the angle of the backrest 2 and the footrest 3 according to his or her own sitting habits. At the same time, the electric adjustment component is controlled by the remote control, so that the person can adjust the backrest 2 and the footrest 3 at any time during use, which is convenient and quick to improve the comfort of the seat body 1.

[0036] Reference Figure 1 The top ends of the side walls on both sides of the backrest 2 are fixedly connected with electric slide rails 7, and electric sliders 8 are slidably connected to the electric slide rails 7. A U-shaped frame 9 is provided on the top end of the side wall of the backrest 2 away from the fan 6. The two ends of the U-shaped frame 9 are respectively fixedly connected to the electric sliders 8. The side wall of the U-shaped frame 9 away from the backrest 2 is fixedly connected with a head support 10. By starting the electric slide rails 7 at the same time, the electric slider 8 can drive the U-shaped frame 9 to move, which is convenient for adjusting the height of the head support 10 according to the height of the user.

[0037] Reference Figure 1A base 11 is provided on the lower surface of the seat body 1, and an electric telescopic rod 12 is fixedly connected to the upper surface of the base 11. The output end of the electric telescopic rod 12 is fixedly connected to the lower surface of the seat body 1. When people of different heights use the seat body 1 for office work or games, the electric telescopic rod 12 can be activated according to the height of the desktop to raise or lower the seat body 1, and the appropriate height can be adjusted according to the height of the person to facilitate use.

[0038] Reference Figure 2 An electric blanket 13 is provided on the side wall of the backrest 2 away from the fan 6, and a plurality of plug-in blocks 14 are fixedly connected to the side wall of the electric blanket 13 close to the backrest 2, which are respectively plugged into the heat dissipation holes 4. The thickness of the electric blanket 13 is less than the distance between the U-shaped frame 9 and the backrest 2, which prevents the U-shaped frame 9 from colliding with the electric blanket 13 when driving the head support 10 to move, causing the electric blanket 13 to be pushed and deformed. When used in winter, the plug-in blocks 14 can be inserted into the heat dissipation holes 4, and the electric blanket 13 can be laid on the backrest 2 to block the heat dissipation holes 4. While preventing heat from dissipating, the electric blanket 13 can also be started to heat the backrest 2, thereby improving the comfort of people using it.

[0039] Reference Figure 2 A first filter plate 15 is installed at one end of the return frame 5 away from the backrest 2. The first filter plate 15 can protect the fan 6 to prevent the fan 6 from sucking objects into the return frame 5 through suction during operation, causing direct contact with the fan 6 and damaging the fan 6.

[0040] Reference Figure 3 A second filter plate 16 is fixedly connected to one end of the inner wall of the heat dissipation hole 4 near the fan 6. Through the second filter plate 16, objects can accidentally enter the return frame 5 from the heat dissipation hole 4 and come into contact with the fan 6, causing damage to the fan 6. At the same time, it can prevent hair from entering the return frame 5 from the heat dissipation hole 4 when people lean on it, and getting entangled with the fan 6, causing injury to people.

[0041] Reference Figure 1 A hole 17 is provided on the armrest of the seat body 1 and a sleeve 18 for placing items is fixedly connected under the hole 17. The sleeve 18 can be fixedly connected to the armrest of the seat body 1 by bolts. When debris, dust and other debris are generated inside the sleeve 18 and are difficult to clean, the bolts can be unscrewed, the sleeve 18 can be removed, and the sleeve 18 can be cleaned. Through the hole 17 and the sleeve 18, items such as water cups and mobile phones carried by people can be stored to prevent the problem that personal items cannot be placed when people lie on the seat body 1, causing inconvenience.

[0042] Reference Figure 4The four side walls of the return frame 5 close to the first filter plate 15 are provided with fixing bolts 19. The fixing bolts 19 all pass through the return frame 5 and are threadedly connected to the first filter plate 15. By rotating the fixing bolts 19 and removing the fixing bolts 19, the first filter plate 15 can be disassembled, which is convenient for maintenance or replacement of the fan 6 and prevents the fan 6 from being damaged and difficult to disassemble.

[0043] The implementation principle of this application is: when in use, when a person sits on the chair body 1, he can operate the remote control to control the electric adjustment component to adjust the angle of the backrest 2 and the footrest 3 according to his sitting habits, and at the same time start the electric slide rail 7 to make the electric slider 8 drive the U-shaped frame 9 to move up and down, adjust the position of the headrest 10, and improve the comfort of the person. At the same time, the water cup, mobile phone and other items carried with him can be placed in the sleeve 18 through the hole 17 to store them, which improves convenience. When the back rests on the backrest 2 for a long time and sweats, the fan 6 can be started to The air is sucked in and then blown toward the back of the person through the heat dissipation holes 4, so that the air contacts the back of the person, and the air flow is rolled up to dissipate the heat accumulated between the backrest 2 and the person, thereby improving the heat dissipation effect of the heat dissipation holes 4, cooling the back of the person, and preventing the back from sweating easily due to leaning on the backrest 2 for a long time in hot summer. When used in winter, the insert block 14 can be inserted into the heat dissipation hole 4, and the electric blanket 13 can be laid on the backrest 2 to block the heat dissipation hole 4 to prevent the heat from dissipating. At the same time, the electric blanket 13 can be started to heat the backrest 2, thereby improving the comfort of the person.
