Description

Novel ventilating and heating cushion

Technical Field

The utility model relates to a cushion especially relates to a novel heating cushion ventilates.

Background

At present, 4 fan position arrangements are generally adopted on the ventilation seat cushion structure.

1. The edges of the fans are distributed, and the upper end surfaces of the fans are completely exposed outside; for the arrangement, the air inlet of the fan is easy to be blocked by foreign objects, such as clothes worn by a user, small paper scraps and the like, and for families with children, the children are difficult to avoid playing delicately and the like; if the fan is arranged at the rear side close to the hip and the lower side of the waist of the human body, the waist pad cannot be used, and the air opening of the fan can be blocked by the waist pad. This adds inconvenience to the smaller person.

2. The fans are arranged inside and are covered by the ventilation material; for the arrangement, the air inlet volume of the fan is greatly influenced, and the air outlet volume is not ideal. In order to increase the air quantity, the number of the fans can be increased. However, increasing the number of fans necessarily increases the amount of noise. The fan is arranged in the seat cushion, and under the condition of long-term riding and pressing, particularly for heavy personnel, the fan part is extruded, so that the performance and the service life of the fan are influenced.

3. The inner part and the edge of the fan are arranged, and the fan is covered; although the arrangement has the arrangement of the side edges, the fans arranged inside still have the 2 problems, and the fans arranged inside and at the edges still have insufficient wind power. The number of the fans is large, and the noise is large.

4. The fans are arranged independently, and wind is guided in by the wind guide pipes or the grooves. The arrangement of the fan is usually adopted, and the fan is usually placed at the front end (lower side of the knee) of the seat. With this arrangement, the wind power of the backrest is significantly affected because of the lack of wind power due to the distance from the wind source; with the fan in this position, both noise and safe driving are bad feelings for the driver.

5. The cushion heats up more slowly. The sensation of heat usually takes 10 to 20 minutes.

In the current market, no matter what kind of fan arrangement is adopted, the cushion (and the back cushion) is generally thicker, generally 30-40mm, and some are thicker. An excessively thick cushion will be a bad feeling for the taller and shorter persons, and is more disadvantageous for the driver. It is well known that for cars, the space is limited and the range of height adjustment of the seat is limited. The too thick cushion makes the high personnel probably touch the roof, and the personnel of individual short head, seat adjust to minimum, and separation and reunion or brake or throttle can not step on the bottom position. This is disadvantageous for safe driving.

In short, the ventilation heating cushion on the current market has insufficient air quantity, overlarge sound quantity or over-thick thickness, and is generally 30-40 mm. The insufficient air volume can not meet the requirement of comfort in summer; too much sound also affects the comfort level of people for the environment; for the pad with the excessive thickness, inconvenience is brought to passengers in the car, and particularly, safe driving is influenced for the personnel with small heads and short feet. Therefore, the development of a novel ventilating and heating cushion becomes a problem to be solved by those skilled in the art.
