Abstract

The utility model provides an improved forced ventilating permeability mattress, which is characterized in that a blower capable of blowing airflow into the interior of a soft permeability mattress body is connected to the soft permeability mattress body; the interior of the soft permeability mattress body is provided with a main pipe connected with the blower; the main pipe is divided into a plurality of branch pipes distributed in the soft permeability mattress body uniformly; every branch pipe is provided with a plurality of punched holes for the airflow to flow out; airflow passing through the punched holes of the branch pipe can split out averagely from the soft permeability mattress body to achieve forced ventilating permeability effect.

Description

The forced ventilation air-permeable mattress

This utility model relates to the filled type pad of a kind of chair, bed or sofa, particularly a kind of pneumatic type pad.

Human body is at long-time seat, when crouching, very easily feel to ache and cause discomfort because of the contact surface pressurized, therefore need configuration one cushion, to alleviate the pressure of people's contact level, but the cushion material is difficult for heat radiation and ventilative not good, after long-time the use, can cause people's contact level high temperature and sweat, form wet, the factor of unfavorable human body such as heat, especially lying on bed for a long time patient and hemorrhoid patients are easier makes that sb.'s illness took a turn for the worse, be head it off, the material that changes cushion makes it heat radiation easily and ventilative, but this kind cushion can cause soft level of comfort to fall the end, therefore, general mode is to re-lay one deck mat on the cushion, particularly dispels the heat easily and gas-pervious mat, such as straw mat that forms with straw plaited or bamboo weaving and bamboo mat, and the granule mat that is concatenated into by pearl or the like, this type of mat still can reduce the soft level of comfort of cushion a little, but can increase breathability and isolation body temperature that cushion uses a little, and its whole structure is not remarkable.

For further improving the effect of cushion, proposed a kind of with inflator pump forced ventilation gas-pervious " Air-permeable mattress ", as shown in Figure 1, this Air-permeable mattress charges into gas by an inflator pump and expands, convex with a plurality of semicircle plenum chambers that interconnect on it, each plenum chamber center offer one-way stream to lyriform pore in order to gas leak, during use, the mat plenum chamber is formed inhomogeneous aspect on pad, make inflator pump restrain into gas produce uneven fluctuation, when the whole centers of gravity of human body are depressed, mat gas flow and obtain buffering forming comfortable effect, gas releases through lyriform pore and can reach air permeable effect simultaneously, but, this kind " Air-permeable mattress " is that inflation forms, and its carrying comfort factor can pin down mutually with the ventilative factor of gas flow, thereby its actual effect remains to be considered.

The purpose of this utility model is that a kind of improved forced ventilation air-permeable mattress will be provided, and air-flow can shed from pad fifty-fifty in its pad, and not influenced by carrying, to obtain good ventilating permeability effect.

This utility model is achieved in that establishes the person in charge with air-guiding who is connected with air-supply arrangement in the pad of cushion, be responsible for difference a plurality of intravital arms of pad that are distributed in are arranged, but each arm is equipped with a plurality of air feed flows effusive perforation, air-supply arrangement agitates air-flow to enter the intravital person in charge of pad, and air-flow sheds from pad via the perforation of arm again.And each Guan Buhui stress deformation.

All lay arm and respective perforations in the pad that the utility model proposes, thereby air-flow can shed from pad fifty-fifty through the perforation of arm, and really towards people's contact level direction, reach the gas-pervious purpose of forced ventilation, make people's contact level keep dry and comfortable comfortable, to the long-term bed patient, can prevent that the pathological changes of skin and muscle from taking place; Be responsible for support simultaneously and be not out of shape, guarantee smooth and easy transmission gas, strengthened the air permeable effect of air cushion because of stressed.

This utility model concrete structure is provided by following examples and accompanying drawing thereof.

Fig. 1 is the sketch map of traditional Air-permeable mattress.

Fig. 2 is that the forced ventilation air-permeable mattress axle that the utility model proposes is surveyed sketch map.

Fig. 3 is the person in charge of Fig. 2 structure and the distribution schematic diagram of arm.

Fig. 4 is that A-A of Fig. 3 is to cutaway view.

Fig. 5 is the cross-sectional schematic of another embodiment of this utility model.

With reference to Fig. 2,3,4, the forced ventilation air-permeable mattress includes a soft pad 1, pad 1 can make the contact surface softness of human body comfortable, and has suitable breathability, pad 1 is established an inlet suction port 2 in marginal position, inlet suction port 2 is in order to help pad 1 external air-supply arrangement 3, air-supply arrangement 3 can agitate air-flow to enter in the pad 1, establish a person in charge 41 who is connected with inlet suction port 2 with delivery air in the pad 1, be responsible for 41 differences and have a plurality of arms 42 that are uniformly distributed in the pad 1, establish a plurality of perforation 421 that are through to arm 42 inside on the arm 42,421 ', therefore, agitating air-flow when air-supply arrangement 3 enters in the pad 1, air-flow was promptly delivered to arm 42 in 41 minutes through being responsible for, again through boring a hole 421,421 ' flows out, form gas-pervious effect and shed from pad 1 fifty-fifty, perforation 421,421 ' is to offer to each side on arm 42, air-flow can be flowed out towards people's contact level direction really, can't be because of boring a hole 421,421 ' is masked and influences gas and flow out, thereby the mutual people's contact level of pad 1 stream through the tool air permeable effect, reach the gas-pervious purpose of forced ventilation, make people's contact level keep dry and comfortable comfortable.

The person in charge 41 and arm 42 are to be located in the framework 5 of soft cushion body 1 inside, to prevent transmission because of pressurized deformation effect air-flow, framework 5 is arranged on pad 1 inside, support column 51 with a plurality of carrying human body gravity, each support column 51 is provided with a plurality of holes 510 that supply arm 42 to pass, the spacing that support column is 51 must have enough width in order to avoid influence air current flow, and therefore, the person in charge 41 and arm 42 can be isolated as to carry gas swimmingly with external force.Another embodiment of the present utility model is characterized in no longer adopting the framework 5 among Fig. 4 as shown in Figure 5, and so the person in charge 41 of this scheme and arm 42 must be made with hard material, can not be subjected to the human body gravity effect, guarantees smooth and easy transmission gas.

In sum, this utility model is forced to agitate air-flow to enter pad 1 with air-supply arrangement 3, and through being responsible for 41 and the guiding of arm 42 and each part of evenly being sent to pad 1 sheds and forced ventilation is ventilative, make sit for a long time, crouch user on pad 1 and the contact surface of pad 1 can keep dry and comfortable comfortable, especially for a long time patient on sick bed couches, more need the device of the ventilative mode of this kind forced ventilation to keep the dry and comfortable of its health, take place with the pathological changes that prevents skin and muscle.
