Description

Technical Field

[0001] This utility model relates to the field of daily necessities, and in particular to a seat cushion with ventilation function that is easy to assemble and maintain. Background Technology

[0002] A seat cushion is a relatively thick soft pad, usually placed on the ground or other chairs. It can provide softer support, a more comfortable sitting posture, and relieve pressure from sitting for a long time. Common types include office chair cushions and car seat cushions. With the development of the times, the styles of seat cushions are changing rapidly, and with the development of the seat cushion market, many seat cushions with ventilation functions have emerged.

[0003] The existing technology has the following problems: Under the existing technology, seat cushions with ventilation function generally have an exhaust fan installed inside the seat cushion. The exhaust fan drives the air circulation to achieve the ventilation effect. More high-end seat cushions also have the function of blowing hot or cold air. However, the existing technology seat cushions need to be connected to an external power source when they are working. In order to meet the power requirements, it is usually necessary to modify the original wiring of the car for retrofitting. This poses a great safety hazard and will also increase the burden on the car battery.

[0004] The interior of existing ventilated seat cushions is filled with power cords and electronic components. When users clean the seat cushions, water and cleaning agents can easily damage and corrode the power cords and electronic components, making cleaning extremely difficult.

[0005] To address these issues, we propose a seat cushion with ventilation and easy assembly and maintenance. Utility Model Content

[0006] This invention provides a seat cushion with ventilation function and easy assembly and maintenance, in order to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a seat cushion with ventilation function and easy assembly and maintenance, comprising a fixed layer, a functional layer detachably installed on the top of the fixed layer, a docking structure installed on the functional layer, and a buffer layer fixedly installed on the top of the functional layer; the functional layer includes a first air cushion, the bottom of the first air cushion being connected through the docking structure, one end of the docking structure being connected through the first air cushion, and the other end being installed through the top of a second air cushion, thereby connecting the two internally; the tops of the first air cushion and the second air cushion are provided with a first air hole and a second air hole; the first air cushion and the second air cushion are detachably installed on the top of the fixed layer, and a buffer layer is fixedly installed on the top of the first air cushion and the second air cushion; a first ventilation support layer and a second ventilation support layer are respectively fixedly installed inside the first air cushion and the second air cushion.

[0008] Preferably, the buffer layer includes a first pad, the first pad having an internal cavity structure, and a first vent hole extending through and fixedly opened at the top of the first pad to the internal cavity. A first buffer ventilation layer is fixedly installed in the internal cavity structure of the first pad. The buffer layer also includes a second pad, the second pad having an internal cavity structure, and a second vent hole extending through and fixedly opened at the top of the second pad to the internal cavity. A second buffer ventilation layer is fixedly installed in the internal cavity structure of the second pad.

[0009] Preferably, the first pad and the second pad are fixedly installed on the top of the first air cushion and the second air cushion, respectively. The bottom of the first pad and the second pad are provided with corresponding holes, which correspond to the first air hole and the second air hole that are opened through the top of the first air cushion and the second air cushion, respectively.

[0010] Preferably, the docking structure includes a double-pass pipe, one end of which is installed through the bottom of the first air cushion and the other end of which is installed through the top of the second air cushion, and the two are internally connected to each other. A connecting pipe is installed through one side of the outer wall of the double-pass pipe, one end of which is installed through the outer wall of one side of the double-pass pipe and the other end is fixedly installed in the valve output end. A connecting pipe is fixedly installed in the valve input end, and the other end of the connecting pipe is fixedly connected to the connecting head.

[0011] Preferably, the output end of the connector is fixedly connected to the input end of the connector, and its input end is externally connected to the air outlet of the car's air conditioning system.

[0012] Preferably, the fixing layer includes a mounting pad, and a corresponding sticker is provided on the top of the mounting pad.

[0013] Preferably, the bottom of the first air cushion and the second air cushion are provided with an adhesive surface that mates with the corresponding adhesive.

[0014] Preferably, the first air cushion and the second air cushion are detachably installed on the top of the mounting pad body by means of the mating surface provided at the bottom cooperating with the corresponding adhesive.

[0015] The beneficial effects of this utility model are:

[0016] This utility model, by providing a fixing layer, allows it to be installed on a car seat. The fixing layer contains corresponding adhesive pads, through which a functional layer can be detachably installed. When ventilation is required, the air inlet of the docking structure is connected to the air outlet of the air conditioner. Cold or hot air from the air conditioner enters the functional layer through the docking structure. The docking structure includes a valve, which can be adjusted to control the flow rate of cold or hot air into the functional layer, achieving a self-regulating effect. The functional layer includes a first air cushion and a second air cushion, each containing a first ventilation support layer and a second ventilation support layer, respectively. The support layer and the second ventilation support layer provide support to ensure that the first air cushion and the second air cushion will not collapse due to external forces. The air conditioner's cold or hot air enters the first air cushion and the second air cushion through the docking structure, passes through the first ventilation support layer and the second ventilation support layer, and is discharged into the buffer layer through the first air hole and the second air hole. The buffer layer is equipped with a first buffer ventilation layer and a second buffer ventilation layer, which provide support and increase user comfort. The air conditioner's cold or hot air will pass through the first buffer ventilation layer and the second buffer ventilation layer and be discharged to the human body and the contact surface through the first air hole and the second air hole, achieving the effect of ventilation.

[0017] This invention enables ventilation without external power supply or dismantling of wiring or car seats. Furthermore, the interior is free of power cords and electronic components. This solves the problem that existing seat cushions require external power to operate, and to meet the power requirements, it is usually necessary to damage the original wiring of the car for retrofitting, which poses a significant safety hazard and increases the burden on the car battery.

[0018] Furthermore, the functional layer and the fixed layer are detachably connected, making it convenient for users to clean and maintain. This solves the problem that in existing technology, the interior of a seat cushion with ventilation function is filled with power cords and electronic components, making it extremely difficult to clean when the user cleans the seat cushion because water and cleaning agents can easily damage and corrode the power cords and electronic components.

The first buffer ventilation layer 43 and the second buffer ventilation layer 46 are used to increase the comfort of the user when riding. The bottoms of the first cushion 41 and the second cushion 44 are provided with corresponding holes. It should be noted that the first buffer ventilation layer 43 and the second buffer ventilation layer 46 are designed with a ventilated structure, such as honeycomb or hollow, or, provided that the corresponding holes of the first air cushion 21 and the second air cushion 22 are not blocked, the first air cushion 21 and the second air cushion 22 can be filled with cushioning and support materials such as sponge and support body.

[0035] like Figure 6-9As shown, the first pad 41 and the second pad 44 of this utility model are respectively fixedly installed on the top of the first air cushion 21 and the second air cushion 22. It should be noted that the first pad 41 and the second pad 44 can be sewn onto the top of the first air cushion 21 and the second air cushion 22, or can be detachably fixed to the top of the first air cushion 21 and the second air cushion 22. By providing an adhesive layer on the bottom periphery of the first pad 41 and the second pad 44, and an adhesive layer on the top periphery of the first air cushion 21 and the second air cushion 22, the first pad 41 and the second pad 44 can be detachably fixed to the top of the first air cushion 21 and the second air cushion 22. Corresponding holes are provided at the bottom of both the first pad 41 and the second pad 44, and respectively... Corresponding to the first air hole 23 and the second air hole 24 that are opened through the top of the first air cushion 21 and the second air cushion 22, the cold or hot air from the car air conditioner enters the first air cushion 21 and the second air cushion 22 through the docking structure 3. The first air hole 23 and the second air hole 24 are opened through the top of the first air cushion 21 and the second air cushion 22. The cold or hot air in the first air cushion 21 and the second air cushion 22 will flow through the first air hole 23 and the second air hole 24 to the corresponding holes opened at the bottom of the first pad body 41 and the second pad body 44, and enter into the interior of the first pad body 41 and the second pad body 44. It will then be discharged from the first vent hole 42 and the second vent hole 45 provided on the two pads to the surface in contact with the human body, thereby achieving the effect of passing through.

[0036] like Figure 10 As shown, the docking structure 3 of this utility model includes a double-pipe 31. One end of the double-pipe 31 is installed through the bottom of the first air cushion 21, and the other end is installed through the top of the second air cushion 22. The double-pipe 31 has a hollow internal structure, allowing the two parts to communicate with each other. A connecting pipe 32 is installed through one side of the outer wall of the double-pipe 31. One end of the connecting pipe 32 is installed through one side of the outer wall of the double-pipe 31, and the other end is fixedly installed in the output end of the valve 33. A connecting pipe 34 is fixedly installed in the input end of the valve 33, and the other end of the connecting pipe 34 is fixedly connected to a connecting joint 35. The connecting joint 35 is shown in the figure. The output end is fixedly connected to the input end of the connector 34. Its input end is connected to the air outlet of the car air conditioner. The cold or hot air from the air outlet of the car air conditioner is introduced into the connector 34 through the connector 35 and enters the connecting pipe 32 through the valve 33. It should be noted that the valve 33 in this embodiment is prior art. Its function is to control the flow rate of cold or hot air flowing into the connecting pipe 32 from the connector 34. The cold or hot air flowing into the connecting pipe 32 will enter the double-pass pipe 31 and be split in the double-pass pipe 31, so that the cold or hot air is introduced into the first air cushion 21 and the second air cushion 22.

[0037] Working principle:

[0038] The outer side of the fixing layer 1 is sewn or equipped with one or more sets of fixing straps, which are used to fix it to the car seat. One end of the docking structure 3 is connected to the air conditioning vent, and the other end is connected to the functional layer 2. When in operation, the car air conditioning is turned on, and the cold or hot air from the car air conditioning will enter the functional layer 2 through the connecting structure and flow through the interior of the functional layer 2 into the buffer layer 4. The buffer layer 4 is used to increase the comfort of the user when riding. After the cold or hot air is introduced into the buffer layer 4 from the interior of the functional layer 2, it flows through the interior of the buffer layer 4 and then flows to the surface in contact with the human body, thereby achieving a ventilation effect. Moreover, the functional layer 2 can be detached and installed on the fixing layer 1, making it convenient for the user to clean the functional layer 2.

[0039] The fixing layer 1 includes a mounting pad 11, with a corresponding sticker 12 on the top of the mounting pad 11. One or more sets of fixing straps can be sewn or set on the outside of the mounting pad 11 so that it can be fixed to other devices, such as seats, car seat cushions, etc. The mounting pad 11 can be detachably installed with a functional layer 2 through the corresponding sticker, which can facilitate the user to remove it and handle it separately.

[0040] Functional layer 2 includes a first air cushion 21, which is connected to a second air cushion 22 via a docking structure 3. When in operation, the cold or hot air from the car's air conditioning system is introduced into the first air cushion 21 and the second air cushion 22 through the docking structure 3 and flows through their interiors. The first ventilation support layer 25 and the second ventilation support layer 26 are respectively provided inside the two air cushions, which play a supporting role and prevent the first air cushion 21 and the second air cushion 22 from collapsing under external pressure. The cold or hot air from the car's air conditioning system flows through their interiors and into the buffer layer 4 through the first air hole 23 and the second air hole 24, and flows through the interior of the buffer layer 4 and finally flows to the contact surface between the buffer layer 4 and the human body, thereby achieving a ventilation effect.

[0041] The buffer layer 4 includes a first cushion 41 and a second cushion 44. Both of them have corresponding holes at their bottoms that correspond to the first air hole 23 and the second air hole 24. The cold or hot air from the car's air conditioning flows through the interior of the first air cushion 21 and the second air cushion 22, and through the first air hole 23 and the second air hole 24 and the corresponding holes at the bottom of the first cushion 41 and the second cushion 44, it flows through the interior of the first cushion 41 and the second cushion 44. The two cushions have a first buffer ventilation layer 43 and a second buffer ventilation layer 46 inside. The first buffer ventilation layer 43 and the second buffer ventilation layer 46 are used to increase the user's riding experience and provide support and cushioning. The cold or hot air from the car's air conditioning flows through the interior of the first cushion 41 and the second cushion 44, and through the first vent 42 and the second vent 45 that are opened through the top of the two cushions, it flows to the contact surface between the buffer layer 4 and the human body, thereby achieving a ventilation effect.

[0042] The docking structure 3 of this utility model includes a double-pipe 31. One end of the double-pipe 31 is installed through the bottom of the first air cushion 21, and the other end is installed through the top of the second air cushion 22. The double-pipe 31 has a hollow structure inside, and the two are interconnected. In operation, the connector 35 is first connected to the air outlet of the car air conditioner. The cold or hot air from the air outlet of the car air conditioner is introduced into the connector 34 through the connector 35, and then enters the connecting pipe 32 through the valve 33. The user can control the flow rate of the cold or hot air flowing into the connecting pipe 32 through the connector 34 through the valve 33. The cold or hot air flowing into the connecting pipe 32 will enter the double-pipe 31 and be split in the double-pipe 31, so that the cold or hot air is introduced into the first air cushion 21 and the second air cushion 22.
