Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to a lumbar support and posture correction seat. Background Technology

[0002] Prolonged sitting in an office chair can pose a potential threat to our lower back health. Incorrect posture not only easily leads to back pain but also negatively impacts overall health. Posture-correcting chairs have become a popular solution, helping us maintain correct posture and thus improving lower back health. These chairs serve two functions: reminding the body to maintain proper posture and providing support for the lumbar spine.

[0003] A search revealed patent publication number CN106361036A, which discloses a temperature-adjustable chair. It includes a chair frame, a seat cushion, and a backrest. The seat cushion is embedded in the seat frame of the chair frame and contains a heating plate. A button and indicator light are located on the side of the chair frame. A miniature fan is embedded in the backrest, and a battery box with a switch is fixed to the backrest. The miniature fan and battery box are connected via a circuit. This patent can achieve both cooling and heating. In summer, the miniature fan installed in the backrest can cool the back of the user, keeping both the back and the chair back dry and reducing bacterial growth. Simultaneously, the non-heat-absorbing side of the seat cushion faces upwards, achieving coolness in summer. In winter, with the non-woven fabric side of the seat cushion facing upwards, the heating plate is activated via a switch. The other side of the seat cushion, made of a non-heat-absorbing material, allows heat to dissipate only from the top, achieving warmth in winter. This structural design has certain flaws. First, the miniature fan mounted on the backrest is easily deformed when a person leans against it, causing it to malfunction. This type of fan-mounted structure is only suitable for hard chair backs and has limitations in use. Second, in summer, it's not just the back that feels hot; the buttocks also feel very hot from prolonged contact with the seat cushion, especially for office workers who sit on it for long periods, making them feel uncomfortable. Third, the above structure is only suitable for fixed seats and cannot allow for arbitrary position changes.

[0004] Given that the current structure still needs further improvement, the key research topic of this utility model will be how to provide a design that can cool down the seat cushion and / or backrest while also being easy to replace and portable. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, the technical problem solved by this utility model is to provide a lumbar support and posture correction seat that can cool down the seat cushion and / or the seat back.

[0007] Furthermore, the surface of the seat is provided with a first groove at intervals, and the surface of the lumbar support is provided with a second groove at intervals, with the pipe disposed within the first and second grooves. By providing grooves on the surfaces of the seat and lumbar support and arranging the pipe within these grooves, the pipe is prevented from deforming and becoming obstructed when a person sits on the seat.

[0008] Furthermore, a heating device is provided on the surface of the pipe, and the heating device is installed between the pipe and the breathable pad.

[0009] Furthermore, the heating device is a heating film.

[0010] Furthermore, a first switch is installed between the air pump and the pipe provided on the seat, and a second switch is installed between the air pump and the pipe provided on the lumbar support. These switches allow for ventilation of the seat cushion and / or the seat back.

[0011] Furthermore, the openings of the ventilation holes are positioned facing the surface of the breathable pad. This arrangement allows for better ventilation of the seat cushion and backrest.

[0012] The beneficial effects of this utility model compared with the prior art are as follows: Since the lumbar support and the seat surface are respectively provided with pipes at intervals, and ventilation holes are provided on the pipes at intervals, one end of the pipe is connected to an air pump, and the other end of the pipe is sealed, it can achieve cooling on the seat cushion and / or the backrest, greatly enhance the breathability of the seat cushion and the backrest, enhance the comfort of the waist and buttocks when using the main body of the seat, and can further accelerate the heat dissipation of the backrest and seat cushion when getting up or adjusting the sitting posture after sitting for a long time. It also helps the airflow during long-term sitting, thereby timely removing the heat accumulated between the waist and the lumbar support, and between the buttocks and the seat cushion.
