Description
Technical field
The utility model is on a kind of gas constant-voltage equipment, refers in particular to a kind of make inflatable body in the larger ring of the temperature difference
The gas constant-voltage equipment easily used is remained under border.
Background technology
Due to aerated product (such as：Air-filled biscuit, inflatable chair cushion, inflatable surfboard ... etc.), all use mostly
It is a kind of can inflation/deflation design, using the tuyere for being arranged at aerated product, its inside is inflated, make its expansion formed sit
Pad, mattress or surfboard ... etc., lie down, by sitting or being moved for user, if tuyere is opened, can make in aerated product
The gas leakage in portion, to reduce the volume of aerated product beneficial to storage, and lifts the convenience carried.
However, the aerated product for having been filled with enough gas is in the outdoor environment of high temperature in use, inside it for a long time
Gas can then be heated and volumetric expansion so that the pressure rise inside aerated product, if aerated product can not bear it is higher
During pressure, then it can produce deformation and even burst open, cause aerated product to damage.
Therefore, in order to overcome such a problem to produce, there is dealer by way of losing heart, allow aerated product to discharge at high temperature
Portion gas so that internal pressure is unlikely to that aerated product generation deformation can be made even to burst open, and still, works as outdoor environment temperature
During decline, due to previous discharge part gas, cause the deficiency of the gas flow inside aerated product and produce atrophy, it is necessary to go again
Inflation is just used.
It can be filled in conclusion the creator of the utility model concentrates on studies, thinks and design a kind of order through pains for many years
Gas body remains to the gas constant-voltage equipment easily used under the larger environment of the temperature difference, to be subject to for the shortcomings that known techniques
Improve, and then the implementation in enhancement industry utilizes.
Utility model content
The main purpose of the utility model, is to provide a kind of gas constant-voltage equipment, when temperature rises, by inflatable
The portion gas that the elastic balloon storage inflatable bodies of contraction are discharged, and when the temperature drops, can be by elastic balloon in itself
Convergent force by stored gas extrusion return body interior, make main body in temperature change, can keep definite shape without
Deformation, damage or atrophy can be produced, to lift the robustness of main body, while also need not again be inflated, reduce user
Burden.
Therefore, in order to achieve the above object, the utility model is a kind of gas constant-voltage equipment, it includes：One inflatable bodies, in
The main body is equipped with a tuyere, which is to be connected to the body interior by a gas passage, so that user passes through the tuyere
Inflation/deflation is carried out to the main body, and the body interior is equipped with a plurality of drawstring, to connect the upper epidermis of the main body and layer；And
The one inflatable elastic balloon shunk, is connected with the gas passage；Wherein, when the main body be heated heating and in the body interior
Volume expansion when, which is to be subject to the limitation of the drawstring and can not expand, and then portion gas is poured into the bullet
In property air bag, make the elastic balloon with expansion；Afterwards, when main body cooling in the gas volume contraction of the body interior
When, it is that the gas extrusion previously poured into the elastic balloon is returned by the body interior by the convergent force of the elastic balloon, makes this
Body interior has enough gas flows without atrophy.
Gas constant-voltage equipment from the above, the wherein elastic balloon are for rubber or silica gel.
Gas constant-voltage equipment from the above, the wherein elastic balloon are that have a ball-type gas chamber.
Gas constant-voltage equipment from the above, the wherein main body are for an aerated product.
The beneficial effects of the utility model are, when temperature rises, can be filled by the inflatable elastic balloon storage shunk
The portion gas that gas main body is discharged, and when the temperature drops, can be by the convergent force of elastic balloon in itself by stored gas
Body interior is extruded back, makes main body in temperature change, definite shape can be kept without producing deformation, damage or atrophy,
It to lift the robustness of main body, while also need not again be inflated, reduce the burden of user.
Brief description of the drawings
To further illustrate the technology contents of the utility model, with reference to embodiments and attached drawing is described in detail as after, its
In：
Fig. 1 is the schematic perspective view of the utility model gas constant-voltage equipment.
View when Fig. 2A -2B are the body heating of the utility model gas constant-voltage equipment.
View when Fig. 3 A-3B are the body cooling of the utility model gas constant-voltage equipment.
Embodiment
Refering to Figure 1, the utility model is a kind of gas constant-voltage equipment 10, it includes：One inflatable bodies 11, in
The main body 11 is equipped with a tuyere 12, which is to be connected to by a gas passage 13 inside the main body 11, for user
Inflation/deflation is carried out to the main body 11 by the tuyere 12, and the main body 11 is internally provided with a plurality of drawstring 111, to connect the main body 11
Upper epidermis 112 and layer 113；And the inflatable elastic balloon 14 shunk, it is to be connected with the gas passage 13.
Then, refer to shown in Fig. 2A, Fig. 2 B, user can prior to indoor or temperature relatively lower to the main body 11 into
Row inflation, takes outdoor or temperature relatively eminence and uses again after the completion of inflation, wherein the main body 11 can gradually be heated heating and
Gas volume inside the main body 11 also can gradually expand, but the main body 11 be subject to the drawstring 111 limitation and can not
Expansion so that the pressure inside the main body 11 gradually rises, and then portion gas is poured into pressure by pressure higher main body 11
In relatively low elastic balloon 14, make the elastic balloon 14 with expansion, the main body 11 is not produced deformation or is burst open and damage
It is bad.Since the elastic balloon 14 is as made by the materials such as rubber or silica gel, so with quite good elastic and pressure-resistant journey
Degree, so that the elastic balloon 14 is not easy to burst open because of expansion, the elastic balloon 14 has a ball-type gas chamber in addition, with storage
Deposit the portion gas poured into by the main body 11.
Furthermore refer to shown in Fig. 3 A, Fig. 3 B, during use, if the temperature of environment is relatively previously low, the main body
11 can the gradually cooling and gas volume inside the main body 11 is when can also gradually taper up so that pressure inside the main body 11 by
Gradually decline, be at this moment by the elastic balloon 14 convergent force of itself, will previously pour into the gas extrusion in the elastic balloon 14
Return inside the main body 11, making still to have inside the main body 11 need not also fill again with enough gas flows without atrophy, user
Gas.
However, above-described main body 11 is for an aerated product, such as：Air-filled biscuit, inflatable chair cushion, inflatable
Surfboard, tracheae (pillar) part of air dome and any outdoor aerated product ... wait all can, be not limited with these examples.
Therefore the utility model provides a kind of gas constant-voltage equipment really, when temperature rises, inflatable contraction can be passed through
The portion gas that elastic balloon storage inflatable bodies are discharged, and when the temperature drops, the contraction of elastic balloon in itself can be passed through
Stored gas extrusion is returned body interior by power, is made main body in temperature change, can be kept definite shape without producing
Deformation, damage or atrophy, to lift the robustness of main body, while also need not again be inflated, reduce the burden of user.
