[0002] Office chairs, as an indispensable part of the work environment, are designed to provide employees with a comfortable, healthy, and efficient work experience. With the continuous advancement of modern office concepts, office chair design is increasingly emphasizing human-centered design, functionality, and environmental friendliness. High-quality seat cushions and backrest materials (such as memory foam, breathable mesh, or leather) provide good support and breathability, reducing discomfort from prolonged sitting. However, due to the limitations of current work environments and work hours, people often need to sit in chairs for extended periods. This causes heat to accumulate between the chair and the body, compressing the body and causing various physiological discomforts.

[0003] Existing technology (Chinese Patent No.: CN214156822U) discloses a ventilated seat cushion for a chair, which uses a limited air source and a matching air guide plate installed inside the seat to isolate the body from direct contact with the elastic plate on the seat and to deliver air to the contact area. However, it uses an external suction air source, which poses many environmental discomforts in office spaces and is difficult to promote. Utility Model Content

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control. Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0026] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Depend on Figure 1-7The ventilated seat cushion shown includes a mounting sleeve 1. A lifting seat plate is slidably connected to opposite side walls of the mounting sleeve 1. A first bracket and a second bracket are fixedly connected to the bottom surface of the lifting seat plate. A telescopic component 2 is fixedly connected between the first bracket and the second bracket. A sponge layer 3 is fixedly connected to the top surface of the lifting seat plate, enhancing the comfort of the user. Expansion joints 4 are formed on opposite sides of the sponge layer 3. By pulling the bottom surface of the sponge layer 3 with the lifting seat plate, the expansion joints 4 can be opened. A first sliding plate 9 and a second sliding plate 10 of the lifting seat plate stretch the expansion joints 4 into several equally spaced ventilation chambers 5, allowing body heat to penetrate through the cover 6 and the sponge layer 3 and dissipate through the ventilation chambers 5. A cover 6 is fixedly connected to the top surface of the mounting sleeve 1, and the sponge layer 3 is disposed within the inner cavity of the cover 6. Both the sponge layer 3 and the cover 6 have ventilation holes 7 on their surfaces. The cross-sectional structure of the sponge layer 3 is consistent with that of the cover 6. For simplicity, the ventilation holes 7 of the sponge layer 3 are not shown in the accompanying drawings.

[0028] Further optimize the plan, by Figure 2 As shown, the mounting sleeve 1 has T-shaped grooves 8 on its opposite sidewalls. The lifting seat includes several first sliding plates 9 and several second sliding plates 10, which are arranged adjacently and in close contact. Sliding columns 11 are fixedly connected to both ends of the first sliding plates 9 and both ends of the second sliding plates 10. A limiting plate 12 is fixedly connected to one end of each sliding column 11. The sliding columns 11 and the limiting plate 12 are slidably connected to the T-shaped grooves 8. The T-shaped grooves 8 guide the sliding columns 11, allowing the first and second sliding plates 9 and 10 to move up and down along the T-shaped grooves 8. The first and second sliding plates 9 and 10 also rub against each other, providing mutual guidance. The limiting plate 12 fixes the first and second sliding plates 9 and 10 into the mounting sleeve 1, thereby enhancing the strength of the mounting sleeve 1 and reducing the cost of structural reinforcement. The top surfaces of the first and second sliding plates 9 and 10 are fixedly connected to the bottom surface of the sponge layer 3.

[0029] Further optimize the plan, by Figure 2 As shown, the first bracket includes two first crossbeams 13. The top surface of the first crossbeams 13 is fixedly connected to the bottom surface of the first slide plate 9. The bottom surfaces of the two first crossbeams 13 are fixedly connected to a first fixing plate 14. The first fixing plate 14 is fixedly connected to the telescopic member 2. By pulling the first fixing plate 14 through the telescopic member 2, the first crossbeams 13 can be driven to pull all the first slide plates 9 up and down.

[0030] The scheme is further optimized. The second bracket includes two second crossbeams 15. Several connecting blocks are fixedly connected to the top surfaces of the two second crossbeams 15 at equal intervals. The connecting blocks are fixedly connected to the bottom surface of the second slide plate 10. The bottom surfaces of the two second crossbeams 15 are fixedly connected to second fixing plates 16. The top surface of the second fixing plates 16 is fixedly connected to the telescopic member 2. By pulling the second fixing plates 16 through the telescopic member 2, the second crossbeams 15 can be driven to pull all the second slide plates 10 up and down.

[0031] Further optimize the plan, by Figure 7 As shown, one end of the sponge layer 3 is also fixedly connected to an airbag 17. A first one-way valve 18 is fixedly connected to and connected to one side of the airbag 17, which can inflate the airbag 17 from the outside. Several second one-way valves 19 are fixedly connected to the bottom surface of the airbag 17. The second one-way valves 19 are connected to the expansion joint 4, and can blow air from the inside of the airbag 17 to the outside.

[0032] Furthermore, the airbag 17 is positioned close to the human thigh, and through the movement of the human leg, the airbag 17 can be continuously compressed and rebounded, allowing the compressed gas to be introduced into the ventilation cavity 5, thereby improving the efficiency of heat dissipation from the human body.

[0033] Further optimization of the design: the airbag 17 is made of elastic rubber material, and the side wall of the airbag 17 is embedded with an elastic spring strip 20. The spring strip 20 is embedded in the inner wall of the airbag 17, which can enhance the support force of the airbag 17 by utilizing the elasticity of the spring strip 20, and also improve its recovery force, making it easier to inflate and deflate.

[0034] Further optimization of the design: telescopic component 2 is a pneumatic cylinder or an electric cylinder.

[0035] Furthermore, the telescopic component 2 can be replaced with a manual hydraulic strut or a manual jack, reducing the requirement for external energy supply.

[0036] The working process of this embodiment is as follows:

[0037] When a person sits on the seat cushion, heat accumulates between the person and the seat cushion. Most of the heat is then directed into the ventilation cavity 5 through the ventilation holes 7 of the leather cover 6 and the foam layer 3. The ventilation cavity 5 forms an air duct, and the flow of external air through the ventilation cavity 5 can quickly dissipate heat, improving the comfort of the person.

[0038] After the first slide plate 9 has been in contact with the human body for a certain period of time, in order to alleviate the discomfort of the human body's buttocks, the telescopic component 2 is activated to pull the first slide plate 9 and the second slide plate 10, so that the two are close to each other until the first slide plate 9 touches the bottom surface of the T-shaped groove 8. Then the second slide plate 10 will rise to contact the human body and be offset from the first slide plate 9. The first slide plate 9 will continue to pull the bottom surface of the sponge layer 3 to form a new ventilation cavity 5, maintaining the heat dissipation effect of the seat cushion.

[0039] Furthermore, in order to improve the heat dissipation efficiency of the seat cushion, an airbag 17 is fixedly connected to one end of the sponge layer 3. Through the natural movement of the human leg, the airbag 17 can be continuously squeezed and relaxed, so as to continuously inflate and deflate the airbag 17 and provide the power for active exhaust of the ventilation cavity 5.

[0040] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
