Description

Breathable seat cushion

technical field

The utility model "breathable seat cushion" aims to provide a seat cushion with the function of ventilation and heat dissipation, which can be added or built into a car seat, or any other place where users can sit or lie, such as homes and offices.

Background technique

Seat cushions are common items used to increase ride comfort. In order to improve the stuffiness caused by sitting on the seats, many users will weave grass and wood into seat cushions and place them on the seats to improve ride comfort. It is cooler, or a granulated curtain seat cushion made of wood or plastic can improve the ventilation effect of the seat.

Although the seat cushion made of weaving grass or wood or plastic is common and low in cost, the seat cushion itself does not have a cooling function, and usually cannot meet the user's expectations and needs in hot summer.

And if a cooling device is buried in the seat, the waste heat generated during the operation of the cooling device is not only difficult to dissipate heat, but also likely to cause the problem that the position where the user sits is not ventilated and affects blood circulation or local stuffy sweating. Designing a seat cushion that can be built in or added to the seat for ventilation and heat dissipation is a problem that the designer wants to solve urgently.

Contents of the invention

The main purpose of this utility model is to provide a "breathable seat cushion", especially a seat cushion with ventilation and heat dissipation functions without an external refrigeration device, which can be added or built in a car seat, or other household, Any place where users can sit or lie down, such as offices.

In order to achieve the above purpose, the utility model "breathable seat cushion" is arranged on the seat for the user to sit on. The seat cushion includes a breathable outer layer and a bottom lining, and a breathable outer layer and a bottom lining The wind deflector and at least one fan are externally provided with a control unit electrically connected to the fan to control the operation and stop of the fan; the aforementioned bottom liner includes a barrier layer adjacent to the wind deflector and an inner layer below the barrier layer Lined with a sponge layer, the air deflector is provided with a plurality of through holes that penetrate up and down. One side of the air deflector is adjacent to the air-permeable outer layer, and the other side is provided with a passage for air circulation between the bottom lining and the passage near the side. At least one opening is provided at the side for fixing and ventilating the aforementioned fan; in addition, the air deflector is provided with a plurality of through-holes penetrating up and down. To let the air-permeable seat cushion have the effect of ventilation and heat dissipation.

The air-permeable seat cushion has two main implementations, one of which is built into the seat and combined with the seat; the other is added to the seat to improve the convenience of use. When it is implemented in combination with a seat, the seat is provided with an accommodating groove for embedding a breathable seat cushion, and the lining sponge layer is arranged at the bottom of the accommodating groove, so that the seat cushion is integrated on the seat.

When the aforementioned air-permeable seat cushion is implemented, it can further include a heating unit arranged between the air-permeable outer layer and the wind deflector. The seat cushion has the effect of heating and keeping warm.

In order to increase the comfort of the occupants, a sandwich mesh can be further arranged between the air-permeable outer layer and the wind deflector, so that the air-permeable seat cushion feels more comfortable to ride.

Compared with the previous technology, the utility model has the function of ventilation and heat dissipation without external heating and cooling devices, so it can achieve the effect of low cost and convenient use.
