Description

Technical Field

[0001] The invention relates to the technical field of seat cushions, in particular to a multifunctional seat cushion provided with a pulling structure. Background Art

[0002] In today's fast-paced life and work environment, people have put forward higher and higher requirements for the comfort, functionality and convenience of daily necessities. As a common daily necessity, cushions are widely used in various fields such as office places, home environments, and transportation. However, the existing cushions have many shortcomings in actual use, which has also prompted us to conduct in-depth research and development of functional cushions. The cushions on the market currently have the following problems: Traditional seat cushions are usually simply placed on the seats without effective fixing methods. During use, especially when people move frequently or the seat surface is relatively smooth, the seat cushions are prone to sliding and shifting, which not only affects the user's comfort, but also may cause the user to be unstable when adjusting the sitting posture, increasing the risk of accidents. For example, in an office environment, when people quickly get up to get documents or communicate with colleagues, the sliding of the seat cushion may cause the user to lose balance. At the same time, most existing seat cushions only have basic sitting functions and cannot meet people's diverse needs. With the improvement of people's living standards and the increasing attention to health, the functional expectations for seat cushions are also getting higher and higher. For example, people who sit in the office for a long time hope that the seat cushion can provide certain lumbar support to relieve lumbar fatigue. In cold seasons, people hope that the seat cushion can have a heating function to provide a warm sitting feeling. For people who travel frequently, they hope that the seat cushion can be easy to carry and store to meet the use needs of different places. However, existing seat cushions often cannot meet these functional requirements at the same time, so people have to use other auxiliary equipment during use, which increases the cost and inconvenience of use.

At this time, the suction plate 14 turns to the seat surface where the seat cushion 1 is placed as the switch rod 13 rotates. The contact and adsorption of the suction plate 14 with the seat surface prevents the seat cushion 1 from sliding relative to the seat, thereby ensuring the stability of the seat cushion 1 when used.

[0030] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment discloses that a heating mechanism is provided inside the seat cushion 1, and the heat inside the function box 12 is efficiently preserved when no one is using it by monitoring the usage status; The heating mechanism includes: an electric heating tube 15, the electric heating tube 15 is fixedly arranged inside the function box 12, and a porous plate 16 is fixedly arranged inside the function box 12 on both sides of the electric heating tube 15, a fan 17 is installed on the outer surface of one side of the porous plate 16, and a switching plate 18 is arranged on the side of the other side of the porous plate 16 facing the outside of the function box 12, and a clearance hole 19 is opened on the outer surface of the switching plate 18, the upper end of the switching plate 18 passes through the upper surface of the function box 12, and the upper end of the switching plate 18 is fixedly connected to a pressure plate 20; The functional box 12 has connecting holes 21 at both ends, and a connecting joint 22 is fixedly installed on the outer surface of the seat cushion 1 facing the connecting hole 21, and a connecting joint 22 is fixedly installed on the outer surface of the seat cushion 1 and the leg support 3, and a connecting hose 23 is connected between the connecting joint 22 on the side surface of the seat cushion 1 and the leg support 3 and the connecting joint 22 on the side surface of the backrest 2; The outer surface of the switching plate 18 is in contact with the outer surface of the porous plate 16 on the same side, and the holes on the surface of the porous plate 16 and the clearance holes 19 are staggered, and a spring is connected between the pressure plate 20 and the upper surface of the function box 12; The inner surfaces of the seat cushion 1, the backrest 2 and the leg support 3 are all penetrated by the connecting joint 22, and the inner cavities of the seat cushion 1 and the leg support 3 are connected to the connecting joint 22; When the heating function is needed, the electric heating tube 15 and the fan 17 are started, the electric heating tube 15 inside the function box 12 heats the air inside the function box 12, the fan 17 is started to guide the air, and the heated air is injected into the backrest 2 and the leg support 3 through the connecting hole 21, the connecting joint 22 and the connecting joint 22 on one side of the function box 12 where the fan 17 is located. After the hot air heats the backrest 2 and the leg support 3, it is sucked into the function box 12 by the fan 17 through the connecting joint 22, the connecting hose 23 and the connecting hole 21 on the other side to be heated again. When the user leaves the seat cushion 1, the pressure plate 20 loses the pressure of the passenger's weight and drives the switching plate 18 to slide up under the support of the spring between the pressure plate 20 and the function box 12. At this time, the displacement holes 19 and the holes on the surface of the porous plate 16 are misaligned, so that the hot air in the function box 12 will not continue to circulate, so that the air temperature in the function box 12 can be maintained at a high temperature level, so as to quickly heat the backrest 2 and the leg rest 3 when the passenger uses it, and at the same time, reduce energy consumption by reducing the heating power after heating the air to a predetermined temperature through the electric heating tube 15.

[0031] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
