A kind of both cooling and heating blowing seat cushion

Affiliated technical field

The utility model relates to a kind of blowing cushion structure, realize the independent assortment on blowing seat cushion shape, the size by modular design, people have been satisfied on the one hand to the different requirements on blowing seat cushion shape, the size, be convenient to make the manufacturing cost that processing has reduced this series products on the other hand, cooperate again with the both cooling and heating air blast, make the blowing seat cushion have alternative refrigeration and heat-production functions.The utility model relates to the correlation technique of Machine Design, materialogy, circuit science, semiconductor refrigerating etc.

Background technology

Blowing seat cushion, the pad that crouches are a kind of novel sitting and sleeping funnitures of rising in recent years, generally be by in the spacer of hollow, drying, pore air-out by the spacer front makes seat person for sleeping in that pure and fresh feel cool be arranged then, but existing blowing seat cushion exists following problem on the market:

(1) bad adaptability of product.

Blowing seat cushion, the pad that crouches generally will be fixed on the utensil of seat, sofa, bed and so on, its blowing seat cushion that needs of different clients varies at size shape, and existing blowing seat cushion mostly is non-modular organization greatly on the market, the demand producer's needs that satisfy different clients are each client, make corresponding product to measure by the difference of its requirement, the versatility of product and relatively poor to the applicability of customer requirement.

(2) function singleness, seasonal adaptation is relatively poor.

Existing blowing seat cushion all adopts hollow pad to add the form of air blast basically on the market, the wind that blows out from seat cushion for the wind of room temperature uniform temp, and this kind blowing seat cushion only is applicable to the season of weather sweltering heat, and is inapplicable basically for the north and extremely frigid zones.

(3) manufacturing process complexity, cost is higher.

The blowing seat cushion of regular manufacturer production on the market, especially its price of seat cushions of drying is all more than 200 yuan, expensive even thousands of units, the one side of tracing it to its cause is the difference on the product materials, be due to the complexity of the manufacturing process that causes owing to the product structure reason on the other hand, certainly some cheap blowing seat cushions are also arranged, but its functional effect is undesirable again.

Summary of the invention

In order to overcome the above-mentioned deficiency of existing blowing seat cushion on the market, the utility model has adopted modular mentality of designing, combination by general basic module, assemble the spacer that meets size that the client requires, increased the adaptability of product on the one hand, satisfy the requirement of different client's differentiation, be convenient on the other hand make and maintenance, significantly reduced manufacturing and the maintenance cost of product.Meanwhile, the utility model adopts the both cooling and heating air blast based on the semiconductor refrigerating module, makes from the spacer front and both can blow out cold wind, common wind, can blow out hot blast again, has improved regional adaptability and the seasonal adaptation of product.

The technical solution of the utility model is: a kind of modular both cooling and heating blowing seat cushion, it is characterized in that described blowing seat cushion is to connect straight flexible pipe (2) and module by general module (1) by module to connect curved flexible pipe formations that be connected to each other, and provide wind regime by the both cooling and heating air blast of based semiconductor refrigeration module (7) formation; Preferably, four air channels and four pores are arranged in the module of described blowing seat cushion (1), four air channels intersect vertically in twos and constitute " well " font, and pore is positioned at the intersection in per two air channels, positive " well " font texture that is useful on air draft in module (1) outside; Preferably, semiconductor refrigerating module (7) is arranged in the both cooling and heating air blast of described blowing seat cushion, semiconductor refrigerating module (7) both sides are equipped with radiator (6), and by blower motor (8), belt driven blower impeller (9) carries out the bilateral air blast.

The beneficial effects of the utility model be the independent assortment by module can satisfy the client to spacer at multifarious needs such as size, shapes, and reduced the manufacturing cost of product, be convenient to make and maintenance; Can between cold wind, hot blast, common wind, switch the double effects that makes spacer have refrigeration and heat freely.
