Description

Technical Field

[0001] This invention relates to the field of office equipment technology, and in particular to an electric chair that can be used in the office. Background Technology

[0002] Smart office solutions mainly include smart office systems, smart power systems, and smart office furniture. In today's office environment, far too many companies rely on computers for work, requiring employees to sit in front of them for extended periods. This prolonged sitting can lead to excessive strain on the lower back and cause fatigue, slowing down work progress and ultimately affecting work efficiency.

[0003] Existing electric office chairs require manual or electric adjustment of their lumbar support structure. Manual adjustment is cumbersome, often requiring bending over or standing to adjust, then leaning back to check comfort, and continuing adjustment until a comfortable level is achieved. This inconvenience hinders usability. While some electric adjustment methods are simpler, prolonged and frequent use can strain the battery, requiring frequent charging, thus limiting practicality. Therefore, this application provides an electric office chair to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an electric chair that can be used in the office to solve the problems mentioned in the background art above.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An electric chair for office use includes a seat, a caster wheel seat installed at the bottom of the seat, a backrest rotatably connected to one side of the seat, and a support unit for auxiliary support provided between the seat and the backrest.

[0007] The support unit includes a pair of first gears fixedly connected to both sides of the chair seat. A connecting sleeve is fixedly connected to the chair back. A pair of sliding sleeves are slidably connected inside the connecting sleeve. A screw is threaded into the sliding sleeve. A second gear is fixedly connected to one end of the screw, and the second gear meshes with the first gear. A piston is fixedly connected to one end of the sliding sleeve corresponding to the inside of the connecting sleeve. A first airbag is installed on the chair back. A pair of first connecting tubes are fixedly connected to the first airbag, and one end of the first connecting tube passes through the chair back and is fixedly connected to the connecting sleeve. The connecting sleeve communicates with the first airbag through the first connecting tube. A seat cushion is provided on the chair seat. A second airbag is provided on the seat cushion. A second connecting tube is fixedly connected to the first airbag. One end of the second connecting pipe is fixedly connected to a telescopic hose, and one end of the telescopic hose is fixedly connected to the second airbag. The first airbag is connected to the second airbag through the second connecting pipe and the telescopic hose. A solenoid valve is installed inside the second connecting pipe. A third connecting pipe is fixedly connected to the connecting sleeve. A third airbag is installed on the chair back, and one end of the third connecting pipe passes through the chair back and is fixedly connected to the third airbag. The connecting sleeve is connected to the third airbag through the third connecting pipe. The solenoid valve is used to control the opening and closing of the first airbag and the second airbag to adjust the support expansion degree of the first airbag. When the second airbag is compressed, it can introduce gas into the first airbag to expand and support the waist. After the user gets up, the first airbag and the second airbag can return to their initial state.

[0008] Preferably, the chair seat is equipped with armrests.

[0009] Preferably, one of the handrails is equipped with a control panel, and the control panel is electrically connected to the solenoid valve.

[0010] Preferably, the connecting sleeve includes a gas storage section in the middle and guide sections at both ends, a pair of pistons are slidably connected to the gas storage section, and the sliding sleeve is slidably connected to the guide section.

[0011] Preferably, the piston slides within a connecting sleeve between the first connecting pipe and the third connecting pipe.

[0012] Preferably, a heating element is installed on the chair back for heating the chair back, and the heating element is electrically connected to the control panel for controlling the activation of the heating element.

[0013] Preferably, the chair back has multiple through holes for air to circulate through.

[0014] Preferably, an electric push rod is provided at the connection position between the universal wheel seat and the chair seat, and the electric push rod is electrically connected to the control panel.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above solution, the existing support structure is replaced by a support unit. The level of support can be adjusted as needed. The adjustment method is simple and easy to use, ensuring that people of different body types can adjust it to the most suitable level of comfort. When the electric chair is adjusted to a reclining chair mode, it can automatically adjust the support mode, reduce lumbar support and strengthen neck support, providing users with better comfort and high practicality.

[0017] By configuring a first airbag, a second airbag, and a solenoid valve, and activating the solenoid valve via the control panel, the user gradually increases the pressure on the second airbag, allowing the first airbag to provide sufficient and comfortable support. At this point, the second airbag is in a deflated state. As the user's buttocks press against the second airbag, it forms a comfortable, concave shape, further improving the user's sitting comfort. This design is highly practical. After use, as the user stands up, the first and second airbags can be automatically restored to their pre-use state, ensuring uninterrupted use by users of different body types. Furthermore, when the electric chair is used alone for an extended period, the first airbag maintains its supportive state while the second airbag remains deflated, allowing for immediate use in the most comfortable position without the need for further adjustments. This design also enhances its practicality.

[0018] By incorporating a first gear, a screw, a second gear, a piston, a first airbag, and a third airbag, when the user needs to use the electric chair in a reclining position, the rotation of the chair back causes the third airbag to inflate. This inflates the third airbag to provide sufficient support for the user's neck while reclining, and simultaneously causes the first airbag to deflate automatically, reducing support for the user's lower back. This does not affect the user's reclining posture and improves the comfort of reclining use, making it highly practical. When the user returns to a sitting position, the first airbag automatically inflates and deflates, ensuring the same comfort when returning to a sitting position. The adjustment is convenient and highly practical. Attached Figure Description

[0034] like Figure 1As shown, an embodiment of the present invention provides an electric chair for office use, including a seat 1, a caster wheel 2 mounted on the bottom of the seat 1, a backrest 3 rotatably connected to one side of the seat 1, armrests 4 mounted on the seat 1, and multiple through holes on the backrest 3 for air circulation. A support unit 5 for auxiliary support is provided between the seat 1 and the backrest 3. The support unit 5 replaces the existing support structure, and the support level can be adjusted as needed. The adjustment method is simple and convenient to use, ensuring that people of different body types can adjust to the most suitable comfort. When the electric chair is adjusted to a reclining position, it can automatically adjust the support mode, reduce lumbar support and strengthen neck support, providing better comfort for the user and making it highly practical.

[0035] like Figure 1-5As shown, the support unit 5 includes a pair of first gears 6 fixedly connected to both sides of the seat 1. A connecting sleeve 7 is fixedly connected to the backrest 3. A pair of sliding sleeves 8 are slidably connected inside the connecting sleeve 7. A screw 9 is threaded inside the sliding sleeve 8. A second gear 10 is fixedly connected to one end of the screw 9, and the second gear 10 meshes with the first gear 6. A piston 11 is fixedly connected to one end of the sliding sleeve 8 corresponding to the inside of the connecting sleeve 7. A first airbag 12 is installed on the backrest 3. A pair of first connecting tubes 13 are fixedly connected to the first airbag 12, and one end of the first connecting tube 13 passes through the backrest 3 and connects to the connecting sleeve 6. A connecting sleeve 7 is fixedly connected to the first airbag 12 via a first connecting pipe 13. A seat cushion 14 is provided on the seat 1, and a second airbag 15 is provided on the seat cushion 14. A second connecting pipe 16 is fixedly connected to the first airbag 12. A telescopic hose 17 is fixedly connected to one end of the second connecting pipe 16, and one end of the telescopic hose 17 is fixedly connected to the second airbag 15. The first airbag 12 is connected to the second airbag 15 via the second connecting pipe 16 and the telescopic hose 17. A solenoid valve is installed inside the second connecting pipe 16. A third connecting pipe 18 is fixedly connected to the connecting sleeve 7. The plug 11 slides within the connecting sleeve 7 between the first connecting pipe 13 and the third connecting pipe 18. A third airbag 19 is installed on the chair back 3, and one end of the third connecting pipe 18 passes through the chair back 3 and is fixedly connected to the third airbag 19. The connecting sleeve 7 is connected to the third airbag 19 through the third connecting pipe 18. A solenoid valve is used to control the opening and closing of the first airbag 12 and the second airbag 15 to adjust the support expansion degree of the first airbag 12. When the second airbag 15 is compressed, it can introduce gas into the first airbag 12 to expand and support the waist. After the user stands up, the first airbag 12 and the second airbag 19... 5. It can restore the initial state. One of the armrests 4 is equipped with a control panel 21, which is electrically connected to the solenoid valve. The connecting sleeve 7 includes an air storage section in the middle and guide sections at both ends. A pair of pistons 11 are slidably connected to the air storage section, and the sliding sleeve 8 is slidably connected to the guide section. A heating tube 20 is installed on the backrest 3 for heating the backrest 3, and the heating tube 20 is electrically connected to the control panel 21 for controlling the start of the heating tube 20. An electric push rod is provided at the connection position between the universal wheel seat 2 and the seat 1, and the electric push rod is electrically connected to the control panel 21.

[0036] In use, the user sits on the second airbag 15 on the seat cushion 14, which provides sufficient comfort. When the user leans back on the backrest 3, and the support from the first airbag 12 on the backrest 3 is insufficient, the solenoid valve can be activated via the control panel 21 to connect the second airbag 15 and the first airbag 12. As the user sits on the second airbag 15, the pressure gradually increases, causing it to compress. The first airbag 12, connected to the second airbag 15, expands, increasing the support until the user feels sufficient support from the first airbag 12. At this point, the solenoid valve can be deactivated via the control panel 21, disconnecting the connection between the first airbag 12 and the second airbag 15. This keeps the first airbag 12 in a slightly inflated state, providing sufficient support for the user. Meanwhile, the second airbag... When the first airbag 12 is in a deflated state, the second airbag 15 is compressed by the user's buttocks, causing it to form a concave shape that fits the user's buttocks, further improving the user's sitting comfort and providing sufficient support for the user's waist. This is highly practical. When the user finishes using the chair and stands up, the second airbag 15 is no longer compressed. The solenoid valve is opened via the control panel 21, which reconnects the first airbag 12 and the second airbag 15, restoring both airbags 12 and 15 to their pre-use state. The solenoid valve is then closed, so as not to affect the next use by users of different body types. When the electric chair is used alone for a long time, the first airbag 12 can maintain its supportive state and the second airbag 15 can remain deflated, so that the user can use it in the most comfortable state without any adjustment the next time. This is highly practical.When the user needs to recline the chair back 3 and use the electric chair in a lying position, the control panel 21 drives the chair back 3 to rotate and tilt. As the chair back 3 rotates, the connection between the first airbag 12 and the second airbag 15 is not affected by the telescopic hose 17. With the rotation of the chair back 3, the first gear 6 moves. With the cooperation of the second gear 10, the first gear 6 rotates. The rotation of the first gear 6 drives the screw 9 to rotate, which in turn drives the sliding sleeve 8 to slide within the connecting sleeve 7. This causes the two pistons 11 to move closer to each other. As the two pistons 11 move closer to each other, the gas between the two pistons 11 is compressed and introduced into the third airbag 19 through the third connecting pipe 18. The third airbag 19 inflates, providing sufficient neck support for the user in a reclining position. Simultaneously, as the two pistons 11 approach each other, they create suction on the first airbag 12, drawing gas from it through the first connecting tube 13 into the connecting sleeve 7. This causes the first airbag 12 to deflate, maintaining the user's reclining position and improving comfort. This design is highly practical. Similarly, when the user returns to a sitting position, the two pistons move away, causing the first airbag 12 to automatically inflate and deflate, and the third airbag 19 to automatically deflate, ensuring the same comfort when returning to a sitting position. This design is easy to adjust and highly practical.

[0037] The technical solution provided by this invention allows the user to use the electric chair in a seated position. First, the user's buttocks rest on the second airbag 15, providing sufficient comfort. When the user leans back against the chair back 3, and the support provided by the first airbag 12 on the chair back 3 is insufficient for comfortable use, the solenoid valve is first activated via the control panel 21, connecting the second airbag 15 and the first airbag 12. Then, as the user sits on the second airbag 15, holding onto the two armrests 4, the buttocks gradually lower, gradually increasing the pressure on the second airbag 15. This causes the second airbag 15 to compress, while the first airbag 12, connected to the second airbag 15, expands, increasing the support for the user's lower back. This continues until the user feels sufficient support from the first airbag 12. At this point, the solenoid valve is closed via the control panel 21, keeping the first airbag 12 in a slightly inflated state to provide sufficient support for the user. Simultaneously, the second airbag 15 is in a deflated state. Because the user's buttocks are compressed onto the second airbag 15, the second airbag 15 forms a contoured, enveloping shape suitable for the user's buttocks, improving the user's seating comfort.

[0038] When the user uses the electric chair in a reclining position, the control panel 21 drives the backrest 3 to rotate and tilt. As the backrest 3 rotates, it drives the first gear 6 to move. With the cooperation of the second gear 10, the first gear 6 rotates. The rotation of the first gear 6 drives the screw 9 to rotate, causing the sliding sleeve 8 to slide within the connecting sleeve 7. This causes the two pistons 11 to move closer together. As the two pistons 11 move closer together, the gas between them is compressed, causing the gas in the connecting sleeve 7 to be introduced into the third airbag 19 through the third connecting pipe 18. This causes the third airbag 19 to inflate, providing sufficient support for the user's neck when reclining. At the same time, as the two pistons 11 move closer together, they move away from the third connecting pipe 18, creating a certain suction force on the first airbag 12. This draws the gas in the first airbag 12 into the connecting sleeve 7 through the first connecting pipe 13, causing the first airbag 12 to deflate. This reduces the support for the user's lower back when reclining, without affecting the user's reclining posture.
