Abstract
The utility model relates to a vacuum bag air exhaust check valve, which comprises a valve seat which is sheathed on a vacuum bag air exhaust hole; the valve seat is hollow, wherein one side of the valve seat, near the air exhaust hole, is connected with a floating sealing piston by elastic material; an air hole is arranged between the sealing piston and the valve seat; the floating sealing piston is formed to be spherical, wherein the diameter of the sphere is bigger than the radius of the vacuum bag air exhaust hole which is sheathed with the valve seat; the spherical floating sealing piston is connected with the valve seat by silica gel material; the other side of the valve seat is provided with a sealing cover; and the check valve is formed into a whole by the silica gel. The vacuum bag air exhaust check valve has the benefits as follows: the whole air exhaust check valve only needs the valve seat and the floating sealing piston to complete the check effect and the sealing effect of the vacuum bag with high sealing property, the product has good independence, the product can be universally used only by arranging the air exhaust hole on the vacuum bag, the application effect is good, the structure is simple, the product can be produced in large scale and low price by means of integral formation, and the market application and the popularization prospect are good.
Description
[technical field]
The utility model relates to a kind of vacuum bag extraction valve, the vacuum bag extraction valve that refers to that especially a kind of versatility is good and have non-return function.
[background technique]
Since vacuum was sobbed the bag appearance, it can be bled to stock and compress the favor that just enjoys people with the advantage of reducing the storing volume greatly.Then early stage vacuum suction band structure is simple and easy, what particularly often adopt in the bleeder hole is valve plug shutoff mode, this just causes the user must seal up the valve plug fast in case leak-stopping gas after finishing bleeding, use very inconvenience, and directly adopt valve plug shutoff mode also to have reasons such as the easy gas leakage of poor sealing.For this reason, the someone has designed the vacuum suction bag that is equipped with check valve, and this kind bled bag by utilizing the about draught head of bleeder hole strengthening plugging effect, but its valve mechanism is all complicated, and directly is arranged in the vacuum bag bleeder hole, can't be general.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, and a kind of vacuum bag extraction valve that is common to all kinds of vacuum bag bleeder holes and simple in structure, good sealing effect and has non-return function is provided.
The purpose of this utility model is achieved in that a kind of vacuum bag check valve of bleeding, its improvements are: it comprises the valve seat that is socketed on the vacuum bag bleeder hole, valve seat hollow, in being connected with the shutoff plug that floats near bleeder hole one side by elastic material, shutoff plug and valve base chamber are provided with air hole;
Described unsteady shutoff plug globulate, its sphere diameter is greater than the radius of valve seat institute socket vacuum bag bleeder hole;
The unsteady shutoff plug of described sphere links to each other with valve seat by silica gel material;
The valve seat opposite side is provided with blanking cover;
Described check valve is one-body molded by silica gel.
Than common vacuum bag extraction valve, the beneficial effects of the utility model are non-return, the plugging effect of vacuum bag that the whole check valve of bleeding only needs valve seat and two critical pieces of shutoff plug that float can be finished high leak tightness, product independence is good, as long as vacuum bag has the bleeder hole can be general on it, effect is good and simple in structure, thereby can be by one-body molded a large amount of cheap productions, the market application and promotion prospect is good.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is structure blast of the present utility model and application schematic representation
Fig. 2 is a structure front view of the present utility model
Fig. 3 is a structure sectional view of the present utility model
[embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
As shown in Figure 1, vacuum suction bag 100 is provided with and seals 101, be provided with bleeder hole 102 in the one side, the utility model relates to a kind of a kind of vacuum bag that uses check valve of bleeding that is common on all kinds of vacuum suction bags 100, it includes valve seat 1, valve seat 1 is connected on the bleeder hole 102 of the bag 100 of bleeding by socket, outside air pump 200 is bled by realization in 1 pair of vacuum bag of valve seat 100, the outside in valve seat 1 then is provided with blanking cover 2, thereby can finish the further shutoff of laggard row and guarantee sealing bleeding.
In conjunction with (a) and (b) among Fig. 2,3 as seen, 1 one-tenth hollow of valve seat, and in being connected with the shutoff plug 110 that floats by elastic material 120 near bag 100 bleeder hole 102 1 sides of bleeding, this elastic material can select silica gel etc. to have the material of certain deformability, and 1 of shutoff plug 110 and valve seat are provided with air hole 130, it is spherical that the shutoff plug 110 that floats is generally, and the sphere diameter of the spherical shutoff plug 110 that floats is greater than the radius of 1 socket vacuum bag 100 bleeder hole 102 of valve seat, thereby guarantee good plugging effect.As seen whole vacuum bag extraction valve structure is very simple, and it is one-body molded to be fit to very much to be suitable for whole silica gel, can further reduce production cost of products.
Thus, this valve seat 1 is when bleeding use, the air of bag in 100 of bleeding will enter in the outside air pump 200 by the air hole 130 of 1 of shutoff plug 110 and valve seat, when the generation of bleeding, after the bag 100 inside and outside formation pressure differences of bleeding, stop in case stopping to bleed, the unsteady shutoff plug 110 that connects in the valve seat 1 promptly can be close on the bleeder hole 102 under the pulling force of elastic material 120 and external air pressure effect, thereby realize preventing the contrary effect that charges into vacuum bag 100 inside that become vacuum of outside air, bleed finish after, the blanking cover blanking cover 2 of valve seat 1 is covered the generation that can further prevent vacuum bag 100 gas leakage, strengthen the sealing effect of the whole check valve of bleeding.
It is to be noted; the utility model is not limited to above-mentioned mode of execution; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description in based on technical solutions of the utility model all belong in the protection domain of the present utility model.
