Description

Technical Field

[0001] The utility model belongs to the technical field of health management, and in particular relates to a health management device. Background Art

[0002] When there is a problem with human health, it can easily be reflected in the breath and body temperature. It is well known that the body temperature will rise when you have a fever, but there may be many reasons for bad breath, which can basically be summarized into four reasons: food-borne, gas-borne, pathogenic, and habitual. The existing human health management devices can manage human health well and promote the development of the health management industry.

[0003] Correct sitting posture can reduce muscle fatigue, support spinal health, improve breathing efficiency and enhance the aesthetics of posture.

[0004] The utility model patent with the publication number CN213249801U discloses a human health management device, including a health management device body, an adjustment bin fixedly connected to the bottom of the health management device body, an anti-skid rubber pad fixedly connected to the bottom of the adjustment bin, a metal bin fixedly connected to the inner top wall of the adjustment bin, and a counterweight fixedly connected to the inner peripheral wall of the metal bin. The human health management device rotates the worm by rotating the turntable, so that the threaded rod rotates through the meshing of the worm wheel and the worm, and the position of the movable plate is limited by providing a telescopic rod, so that the movable plate is threadedly connected to the threaded rod through the threaded through hole and moves up and down, and then the connecting rod squeezes the rotating rod, and further makes the moving wheel contact with the ground, so that the whole device can be supported by the moving wheel, so that the whole device can be moved by the moving wheel when it needs to be moved, reducing the labor intensity of the user.

[0005] Although this technology facilitates movement through the moving wheels, and the moving wheels can be retracted when not needed to make the device more stable, this technology cannot manage people to maintain a correct sitting posture. Long-term incorrect sitting posture will not only increase the pressure and discomfort of the spine, leading to spinal problems such as low back pain, neck pain, and herniated disc, but also cause the muscles of various parts of the body to be in a state of tension for a long time, thereby increasing muscle fatigue and discomfort; it will also affect the image and appearance, affect blood circulation and compress abdominal organs, thereby causing harm to people's health.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0055] Embodiment 1:

[0056] like Figure 1-Figure 3 As shown, this embodiment provides a health management device, including:

[0057] Height-adjustable seat 1;

[0058] A seat cushion 2 is arranged on the top of the height-adjustable seat 1;

[0059] A back support 3 with adjustable position, arranged at the top rear side of the seat cushion 2;

[0060] A base 4 is arranged at the bottom of the height-adjustable seat 1;

[0061] A management component 5 is provided on the height-adjustable seat 1 and is used to manage people to maintain a correct sitting posture;

[0062] The management component 5 includes:

[0063] A support plate 51 is provided on the front side of the upper part of the height-adjustable seat 1;

[0064] A telescopic member 52 is provided on the support plate 51 and is used for adjusting the height;

[0065] The correction plate 53 is disposed on the telescopic member 52 , and the correction plate 53 is located at the front side of the seat cushion 2 .

[0066] In this technical solution, users can adjust the height of the seat according to their personal height and workbench height to ensure that their feet can land smoothly and maintain a good sitting posture. The seat cushion 2 is arranged on the top of the height-adjustable seat 1 to provide a comfortable seat and reduce the pressure on the buttocks and thighs when sitting for a long time. Users can adjust the position of the back support to support their spine and keep them in a correct sitting posture, which can reduce the risk of spinal problems such as low back pain and neck pain. The base 4 is arranged at the bottom of the height-adjustable seat 1 to provide stable support and balance to prevent the chair from tipping over or sliding. The management component 5 is arranged on the height-adjustable seat 1 to manage people to maintain a correct sitting posture. The management component 5 includes a support plate 51, a telescopic member 52 and a correction plate 53. The support plate 51 is arranged on the upper front side of the height-adjustable seat 1 to provide additional support. The telescopic member 52 is arranged on the support plate 51 to adjust the height of the correction plate 53 to adapt to the height and sitting posture requirements of different users. The correction plate 53 is arranged on the telescopic member 52 and is located on the front side of the seat cushion 2 to provide support and correction to help the user maintain a correct sitting posture, prevent the body from leaning forward or tilting, and prevent the user from bending over and lying on the workbench when sitting for a long time to work or study, and ignoring his or her sitting posture, especially when the work or study tasks are tight, which causes the incorrect sitting posture to recur, increasing the risk of spinal and muscle problems, so that the user can sit up straight correctly. Through the above structure and adjustment function, the health management device can help the user maintain a correct sitting posture and reduce the physical discomfort and health problems that may be caused by sitting for a long time, so that the correct sitting posture can help maintain the natural curves of various parts of the body, reduce muscle tension and fatigue, and prevent discomfort caused by sitting for a long time.

[0071] like Figure 1-Figure 3As shown, in this embodiment, the adjustment component 6 is optimized to include:

[0072] There are multiple gear holes 61, which are evenly spaced along the length direction of the telescopic rod 522, and the gear holes 61 pass through the telescopic rod 522;

[0073] A positioning hole 62 is formed on the fixing sleeve 521 , and the positioning hole 62 passes through the fixing sleeve 521 ;

[0074] The latch pin 63 is slidably disposed between the positioning hole 62 and the shift hole 61 .

[0075] In the present technical solution, when it is necessary to adjust the height of the correction plate 53, the user pulls out the pin 63, and then adjusts the relative position of the telescopic rod 522 and the fixed sleeve 521. The telescopic rod 522 drives the correction plate 53 to move, thereby adjusting the height of the correction plate 53. After adjusting it to an appropriate height, the user fixes the pin 63 in the required gear hole 61. The pin 63 passes through the positioning hole 62 and the gear hole 61, ensuring the relative position of the telescopic rod 522 and the fixed sleeve 521. In this way, by moving the pin 63 to different gear holes 61, the length of the telescopic rod 522 can be adjusted, thereby adjusting the overall height of the correction plate 53. Such flexible adjustment improves the convenience of operation.

[0076] Embodiment 3:
