Description

Technical Field

[0001] This utility model relates to the field of seat technology, specifically to a seat high-efficiency ventilation and heating structure device. Background Technology

[0002] In modern life, office chairs and gaming chairs have become an indispensable part of our lives. People use office chairs and gaming chairs for long periods of time for daily work, watching movies, television, and playing games. Statistics show that the average person uses them for 8-10 hours a day. Therefore, improving the comfort of these chairs for long periods of time and reducing user fatigue is of paramount importance.

[0003] However, existing technologies have many shortcomings. Mid-to-low-end chairs typically lack ventilation, and their cushions often use polyurethane foam. Due to the dense structure of polyurethane foam, the cushions become stuffy and hot after prolonged use, and in severe cases, the cushion covering can stick to the skin with sweat. While some mid-to-high-end office chairs and gaming chairs have added heating functions using materials like graphene, the high cost of these materials makes them unsuitable for ordinary chairs, resulting in low adoption rates. Furthermore, the complex auxiliary structural parts increase costs and reduce competitiveness. Some chairs with heating functions have heating structures located around the perimeter of the cushion or with a small heating area, leading to uneven temperatures and poor comfort. Some chairs with ventilation and heating functions require custom-made cushions based on the ventilation and heating module, making the ventilation and heating functions non-universal and resulting in high costs and reduced competitiveness. To ensure smooth airflow for the cooling fan, some seat cushions use less foam, resulting in noticeable variations in foam firmness during use. Over time, this uneven foam deformation negatively impacts both user experience and product appearance. Prolonged use of the ventilation and heating functions requires an external power supply for stable operation, but the rigid connection between the cable and the plug is typically problematic. When the user gets up and leaves, this can easily cause the cable to stretch and damage the plug, or affect other parts, leading to tilting or other issues.

[0004] Therefore, it is necessary to provide a seat ventilation and heating structure device to solve the above-mentioned technical problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5 , Figure 7 One embodiment of this utility model is a high-efficiency ventilation and heating structure device for seats, comprising:

[0036] The seat body 1 includes a seat cushion 11 and a seat frame 12. The seat cushion 11 is fixed on the seat frame 12, and a heating pad 13 is laid flat on the top of the seat cushion 11.

[0037] Ventilation component 2 includes a ventilation fan 21 and a breathable support block 22. The breathable support block 22 is located at the bottom of the seat cushion 11, and the ventilation fan 21 is located below the breathable support block 22.

[0038] More specifically, the bottom of the seat cushion 11 is recessed to form an installation space 14, the breathable support block 22 is embedded in the installation space 14, and the middle of the seat cushion 11 is provided with several ventilation holes 15. The ventilation holes 15 are opened from the top surface of the seat cushion 11 to the bottom surface, and one end of the ventilation hole 15 is connected to the installation space 14, so that the ventilation fan 21 forms a bottom-up ventilation path below the breathable support block 22.

[0039] This embodiment provides a high-efficiency ventilation and heating structure for a seat. Through the cooperation of the seat cushion 11 and seat frame 12 of the seat body 1, the ventilation fan 21 and breathable support block 22 of the ventilation component 2, and the electronic control component 3, it achieves a combination of ventilation and heating functions for the seat, meeting the user's needs in different environments. A heating pad 13 is laid flat on top of the seat cushion 11, ensuring the heating area covers the buttocks and upper thigh area, improving the problems of insufficient heating area and inconsistent temperature in traditional seats, and enhancing heating comfort. The ventilation fan 21 forms an upward ventilation path below the breathable support block 22, and together with the ventilation holes 15 in the middle of the seat cushion 11, allows air to flow smoothly upward from the bottom of the seat, effectively removing heat and moisture generated by the body and solving the problem of stuffiness in the seat cushion 11. The breathable support block 22 provides a stable mounting base for the ventilation fan and also helps with uniform air distribution, further improving ventilation efficiency. The bottom of the seat cushion 11 is recessed to form an installation space 14, in which the breathable support block 22 is embedded. This structural design facilitates the installation and fixation of the breathable support block 22, ensuring that it will not loosen or shift during use. Utilizing the recessed space at the bottom of the seat cushion 11 to install the breathable support block 22 makes reasonable use of the seat's internal space without affecting the overall structure and seating comfort. In this embodiment, the ventilation fan 21 can be one or more of an axial fan, centrifugal fan, mixed-flow fan, or cross-flow fan, with the aim of achieving seat ventilation.

[0040] It should be noted that during the actual use of this device, such as Figure 9 , Figure 10 As shown, the ventilation fan 21 can be located behind the seat cushion 11 and connected to the installation space 14 to form an upward air intake path inside the seat cushion 11, tilted towards the top layer of the seat surface. The installation space 14 can be filled with breathable support blocks 22, spring packs, etc., to avoid completely obstructing airflow, thereby allowing air to flow smoothly from the back of the seat, effectively removing heat and moisture generated by the human body and solving the problem of stuffiness in the seat cushion 11.

[0041] More specifically, please refer to Figure 4 , Figure 5The top of the seat cushion 11 has a recessed mounting surface 16. The depth of the mounting surface 16 is equal to the thickness of the heating pad 13, so that when the heating pad 13 is laid inside the mounting surface 16, the top surface of the heating pad 13 and the seat surface of the seat cushion 11 are on the same plane.

[0042] This embodiment provides a high-efficiency ventilation and heating structure for a seat. The depth of the pre-drilled mounting plane 16 on the top of the seat cushion 11 is equal to the thickness of the heating pad 13, ensuring that the top surface of the heating pad 13 is on the same plane as the seat surface of the seat cushion 11 after it is laid. This avoids the feeling of foreign objects caused by the protruding seat cushion 11 and improves riding comfort. The design of the mounting plane 16 provides a stable mounting position for the heating pad 13, reducing the pressure and wear on the heating pad 13 during use and extending its service life.

[0043] More specifically, please refer to Figure 4 , Figure 5 The seat cushion 11 is covered with a seat cover 17 that fits it. The seat cover 17 has several ventilation holes 18. The heating pad 13 is located between the ventilation holes 15 and the openings of the ventilation holes 18. The heating pad 13 has several linearly arranged hollow air grooves 19.

[0044] This embodiment provides a high-efficiency ventilation and heating structure for a seat. The ventilation holes 18 on the seat cover 17 cooperate with the perforated air channels 19 on the heating pad 13, ensuring heating while maintaining ventilation, thus achieving a balance between breathability and heating. The heating pad 13 is positioned between the ventilation holes 15 and 18. The linear arrangement of the perforated air channels 19 helps guide airflow, allowing air to pass more smoothly through the heating pad 13 and improving ventilation efficiency.

[0045] More specifically, please refer to Figure 4 , Figure 5 , Figure 7 The hollowed-out air duct 19 is elliptical in shape, and the hollowed-out space of the hollowed-out air duct 19 corresponds to the opening of the ventilation hole 15.

[0046] This embodiment provides a high-efficiency ventilation and heating structure for a seat. The perforated air groove 19 is elliptical in shape, corresponding to the opening of the ventilation hole 15. This design reduces airflow resistance, improves airflow efficiency, and further enhances ventilation. The elliptical perforated air groove 19 ensures ventilation while also maintaining the structural strength of the heating pad 13, preventing damage to the heating pad 13 due to excessive perforation.

[0047] More specifically, please refer to Figure 6 , Figure 7 The breathable support block 22 is made of air fiber and is attached to the wall of the installation space 14.

[0048] Optionally, the breathable support block 22 in this embodiment is a spring pack, which consists of several spiral metal springs. Each spring is independently encapsulated in the breathable fabric and arranged in an array with gaps between adjacent springs. Its compression deformation provides support, and it can quickly recover after standing up to relieve the pressure of sitting for a long time and reduce the transmission of vibration. The gaps and the breathable fabric facilitate air flow and form a ventilation path with the ventilation fan 21 to remove moisture and heat. It is installed in the installation space 14 at the bottom of the seat cushion 11 by buckles or other fixing methods, and corresponds to the position of the ventilation hole 15 and the ventilation fan 21 for easy disassembly and maintenance. It also provides an installation base for the ventilation fan 21 and works with the ventilation hole 15 and the hollow air groove 19 to form a complete ventilation system to prevent the seat cushion 11 from deforming.

[0049] This embodiment provides a high-efficiency ventilation and heating structure for a seat. The breathable support block 22 is made of air fiber, which has good breathability and cushioning. While ensuring ventilation, it keeps the softness and hardness of the sponge in the seat cushion 11 consistent throughout, improving seating comfort. The breathable support block 22 is adhered to the wall of the installation space 14, ensuring a firm installation that is not easily detached and that it can function stably during use.

[0050] More specifically, please refer to Figure 6 , Figure 7 A fixed housing 23 is detachably connected to the bottom of the seat frame 12, and a ventilation fan 21 is detachably connected to the inside of the fixed housing 23 so that the ventilation fan 21 can be fixed to the bottom of the seat frame 12 along with the fixed housing 23.

[0051] This embodiment provides a high-efficiency ventilation and heating structure for a seat. The ventilation fan 21 is detachably connected to the inside of the fixed housing 23, which is detachably connected to the bottom of the seat frame 12. This design facilitates the installation, disassembly, and maintenance of the ventilation fan 21, reducing maintenance costs and difficulty. The fixed housing 23 provides a stable mounting support for the ventilation fan 21, ensuring that the fan 21 does not shake or produce noise during operation, thus guaranteeing its stable operation.

[0052] More specifically, please refer to Figure 8 The high-efficiency ventilation and heating structure device for a seat in this embodiment further includes: an electrical control component 3, wherein the magnetic power cord 31 is electrically connected to the control board connection line 32 through a magnetic interface to power the device; wherein the control board 33 is electrically connected to the control board connection line 32 through an onboard connector; the control board 33 is electrically connected to the heating pad 13 through the heating pad connection line 34; and the switch 35 on the control board 33 controls the power-on and power-off operation of the heating pad 13; the control board 33 is electrically connected to the ventilation fan 21 through the fan connection line 36; and the switch 35 on the control board 33 controls the working state of the ventilation fan 21.

[0053] This embodiment provides a high-efficiency ventilation and heating structure for a seat. A magnetic power cord 31 is electrically connected to a control board connection line 32 via a magnetic interface, providing power to the device. This power supply method avoids the damage problems easily caused by rigid connections in traditional wiring, making it more convenient and safer to use. The control board 33 controls the power on / off of the heating pad 13 and the working status of the ventilation fan 21 via a switch 35. Users can flexibly adjust the ventilation and heating functions of the seat according to their needs, making operation convenient.

[0054] Working Principle: This embodiment provides a high-efficiency ventilation and heating structure for a seat. When seat ventilation is needed, the ventilation fan 21 is activated via switch 35, creating airflow below the breathable support block 22. Air flows upward through the air-fiber breathable support block 22, enters the seat cushion 11 through the ventilation hole 15 in the middle, passes through the hollowed-out air groove 19 on the heating pad 13, and exits through the ventilation hole 18 on the seat cover 17, forming an upward ventilation path that removes body heat and moisture, solving the problem of stuffiness. When seat heating is needed, the control board 33 controls the heating pad 13 to be powered via switch 35. The heating pad 13 is laid on the mounting plane 16 at the top of the seat cushion 11, providing even heating to the buttocks and groin area. The electrical control component 3 is connected to an external power source via a magnetic power cord 31.
