Description

Technical Field

[0001] This utility model relates to the field of seat structure technology, specifically to a ventilation structure for a ventilated seat. Background Technology

[0002] Seats can be roughly divided into several parts, including the seat body, headrest, backrest, seat cushion, armrests, and side wings. Traditionally, seats were only used for resting, but with the development of technology, seats have begun to be used in transportation vehicles.

[0003] Existing technologies for traffic operations can no longer meet the needs of simple angle and position adjustments. Various ventilation, heating, and even massage methods are needed, but existing ventilation methods often simply involve adding a fan structure. This type of ventilation can only provide basic ventilation and cannot be adjusted or controlled in terms of temperature. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ventilation structure for a ventilated seat, addressing the shortcomings mentioned in the background art.

[0005] To solve the above technical problems, the technical solution provided by this utility model is: a ventilation structure for a ventilated seat, including a seat body and a backrest body. The seat body includes a bottom equipment cavity and a top mounting groove. Multiple air distribution plates are horizontally fixedly connected to the top of the mounting groove, and multiple air outlets are provided on the top of the air distribution plates.

[0006] The equipment cavity is equipped with an air pump and a temperature control box that are connected to each other. The air pump is connected to an air extraction pipe extending to the outside and a first air outlet pipe communicating with the front end of the temperature control box. The top of the rear end of the temperature control box is connected to a second air outlet pipe extending into the mounting groove. The second air outlet pipe extends to the bottom of the mounting groove and is connected to a gas distribution pipe. The gas distribution pipe is connected to a guide pipe communicating with a gas distribution plate.

[0007] Furthermore, a first temperature sensor is connected inside the equipment cavity, a cooling fan is connected to one side of the equipment cavity, an air collecting shroud that works in conjunction with the cooling fan is connected to the rear side of the seat body, a one-way valve is connected to the air collecting shroud, and an air supply hose is connected to the outside of the air collecting shroud to facilitate heat dissipation inside the equipment cavity.

[0008] Furthermore, a filter screen is connected to the rear side of the seat body to cooperate with the air extraction pipe, so as to prevent foreign objects from entering.

[0009] Furthermore, the temperature control box is equipped with a semiconductor cooling plate, an electric heating grid, and a second temperature sensor. The heat dissipation surface of the semiconductor cooling plate extends to the outside and is connected to a heat dissipation metal plate, which facilitates temperature control operations for cooling or heating the gas.

[0010] Furthermore, a support plate is bolted to the top of the seat body, and the support plate has a through hole that matches the air vent, facilitating the protection of the air distribution plate.

[0011] Furthermore, the inner side of the equipment cavity is provided with a sound insulation layer to prevent excessive noise.

[0012] The advantages of the ventilation structure of this ventilated seat compared with the prior art are as follows: This utility model, by setting multiple air distribution plates in the seat body in conjunction with an air pump and a temperature control box structure, can perform temperature regulation while providing sufficient air supply and ventilation.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-4A ventilation structure for a ventilated seat includes a seat body 1 and a backrest body 2. In actual use, a cushion or similar material is wrapped around the seat body 1 and the backrest body 2. The seat body 1 includes a bottom equipment cavity 3 and a top mounting groove 4. A sound insulation layer 26 is connected to the inner side of each equipment cavity 3. Multiple air distribution plates 5 are horizontally fixedly connected to the top of the mounting groove 4. Multiple air outlets 6 are provided on the top of each air distribution plate 5. A support plate 24 is bolted to the top of the seat body 1. The support plate 24 has through holes 25 that mate with the air outlets 6. By setting the support plate 24, pressure can be prevented from damaging the air distribution plates 5, increasing the protective capability. Therefore, the support plate 24 needs to be made of high-strength metal.

[0020] The equipment cavity 3 is connected to an air pump 7 and a temperature control box 9. The temperature control box 9 is connected to a semiconductor cooling plate 20, an electric heating grid 22, and a second temperature sensor 23. The heat dissipation surface of the semiconductor cooling plate 20 extends to the outside and is connected to a heat dissipation metal plate 21. The air pump 7 is connected to an air extraction pipe 8 extending to the outside and a first air outlet pipe 10 communicating with the front end of the temperature control box 9. The top rear end of the temperature control box 9 is connected to a second air outlet pipe 11 extending into the mounting groove 4. The second air outlet pipe 11 extends to the bottom of the mounting groove 4 and is connected to a distribution pipe 12. The distribution pipe 12 is connected to a guide pipe 13 communicating with the distribution plate 5. Air is drawn in by the air pump 7 and the air is temperature controlled by the temperature control box 9, thereby ensuring that the gas output by the distribution plate 5 is hot or cold, improving the functionality of seat ventilation.

[0021] A first temperature sensor 14 is connected inside the equipment cavity 3. A cooling fan 15 is connected to one side of the equipment cavity 3. A condenser shroud 16 that works with the cooling fan 15 is connected to the rear side of the seat body 1. A one-way valve 17 is connected to the condenser shroud 16. An air supply hose 18 is connected to the outside of the condenser shroud 16. The cooling fan 15 can dissipate the heat generated by the electrical components inside the equipment cavity 3. The air supply hose 18 is generally extended to the outside or into the ventilation system of the transport equipment for external discharge, depending on the actual situation.

[0022] The rear side of the seat body 1 is connected to a filter screen 19 that works with the air extraction pipe 8. The filter screen 19 is only installed at the air extraction pipe 8 to prevent foreign objects from entering the device. If further required, a dust filter can be added. The top air distribution plate 5 does not need to be equipped with a filter because in actual use, a cushion or similar material will be wrapped around the seat body 1 and the backrest body 2, which has its own filtering effect, so there is no need to set up a filter structure.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
