CN202908265U - Autonomous respiration seat surface - Google Patents

Abstract

The utility model discloses an autonomous respiration seat surface. The autonomous respiration seat surface comprises a hot air cavity (1) and a cold air cavity (2) positioned under the hot air cavity (1), wherein a plurality of seat surface exhaust holes (3) are formed in the hot air cavity (1); between the hot air cavity (1) and the cold air cavity (2), air is only allowed to flow from the cold air cavity (2) to a first one-way valve (4) of the hot air cavity (1); and at the lower part of the cold air cavity (2), air is only allowed to flow from the outside to a second one-way valve (5) of the cold air cavity (2). The autonomous respiration seat surface can realize discharge of hot air of the seat surface and entrance of cold air like autonomous respiration through the double-cavity design of the hot air cavity and the cold air cavity, can effectively reduce the temperature and the humidity of the seat surface, and enhances the using comfortable sensation of users.

Description

Face is sat in autonomous respiration

Technical field

The utility model relates to a kind of seat face for seat, and face is sat in specifically a kind of autonomous respiration.

Background technology

If the time that seat is sat in the prior art is longer, the seat face can be overheated, and the seat face is overheated following harm: sit the face stuffiness and cause damp and hot being difficult to be distributed, and be unfavorable for health; The user perspires easily, feels very much oppressed; Produce easily bad mood.The seat face also has the airtight Soft Roll seat of employing face, but following shortcoming is also arranged: ventilatory effect is poor, and heat can't fall apart and remove; Hot-spot, unsuitable sitting; Local humidity is too high, breed bacteria; The seat face is yielding.

In order to solve the overheated problem of seat face, some people's utility model screen cloth sit face, but screen cloth is sat the face good heat dissipation, good permeability, but a lot of shortcomings are also arranged, such as: requirement of strength is high, and inconvenience is installed; The screen cloth life-span is difficult to guarantee; Safety test be difficult to by.

The utility model content

In order to solve the above-mentioned technical problem that exists in the prior art, the utility model provides a kind of autonomous respiration to sit face, comprise: hot gas cavity and the cold air cavity that is positioned at hot gas cavity below, be provided with a plurality of seat face steam vents on the described hot gas cavity, be provided with the first check valve between described hot gas cavity and the cold air cavity.

Further, the bottom of described cold air cavity arranges the second check valve.

Further, described seat face steam vent evenly distributes on the hot gas cavity.

Autonomous respiration seat face of the present utility model is by the dual chamber design of hot gas cavity and cold air cavity, can realize sitting the discharge of face hot gas and entering of cold air, just as autonomous respiration, can effectively reduce and sit surface temperature and humidity, increased user's use comfort.

Description of drawings

Fig. 1 is the schematic diagram that face is sat in autonomous respiration of the present utility model;

Fig. 2 is that this autonomous respiration is sat face along the cutaway view of A-A direction;

Fig. 3 is user's state diagram that face is sat in this autonomous respiration when sitting down;

Fig. 4 is user's state diagram that face is sat in this autonomous respiration when leaving a little.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Such as Fig. 1, shown in 2, autonomous respiration seat face of the present utility model comprises hot gas cavity 1 and is positioned at the cold air cavity 2 of hot gas cavity 1 below, evenly be provided with a plurality of seat face steam vents 3 on the described hot gas cavity 1, be provided with one between described hot gas cavity 1 and the cold air cavity 2 and only allow air to flow to the check valve 4 of hot gas cavity 1 from cold air cavity 2, the bottom of described cold air cavity 2 arranges a check valve 5 that only allows air to flow to cold air cavity 2 from the external world.

As shown in Figure 3, when the user sat down, buttocks was close to the seat face, and it is large that the pressure that the seat face is subject to becomes, and cold air is pressed into the hot gas cavity 1 from cold air cavity 2, and part hot gas is discharged from sitting face steam vent 3, reduces like this and sits surface temperature; When the user left the seat face a little, the pressure that the seat face is subject to diminished such as Fig. 4, and cold air cavity 2 refills cold air.

Shown in the above and the figure only is preferred embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from principle of the present utility model, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.

Claims (3)

1. face is sat in an autonomous respiration, comprise: hot gas cavity (1) and be positioned at the cold air cavity (2) of hot gas cavity (1) below, it is characterized in that: be provided with a plurality of seat face steam vents (3) on the described hot gas cavity (1), be provided with the first check valve (4) between described hot gas cavity (1) and the cold air cavity (2).

2. face is sat in autonomous respiration as claimed in claim 1, and it is characterized in that: the bottom of described cold air cavity (2) arranges the second check valve (5).

3. face is sat in autonomous respiration as claimed in claim 1 or 2, it is characterized in that: described seat face steam vent (3) is in the upper evenly distribution of hot gas cavity (1).
