Description

Technical Field

[0001] The present invention relates to the field of daily necessities, and particularly relates to a valve-free air extraction device. Background Art

[0002] In some areas with heavy rainfall, the high air humidity has always troubled people in storing thick clothes and quilts. Vacuum compression bags are widely used because they have protective functions such as waterproofing, mildew prevention, and moisture protection. A vacuum compression bag is mainly a bag used for packing quilts and various clothes. Its working principle is to suck out the air inside the quilt or clothes (just like squeezing a sponge will make it shrink), so as to reduce the volume, and use the atmospheric pressure to flatten the originally expanded items such as quilts, isolate the outside air, save space, and achieve the effects of dust prevention, mildew prevention, moisture protection, and insect prevention. Currently, the traditional air valves on the market are all sealed with lids, resulting in many air leakage problems and unable to meet the actual use requirements. Summary of the Invention

[0003] To solve the above technical problems, the technical solution provided by the present invention is: a valve-free air extraction device, including a base, a sealing member movably connected to the base, a snap button snap-connected to the base, and an auxiliary member snap-connected to the snap button. A first exhaust hole runs through the center of the base. Upper and lower flanges are respectively provided outward at both ends of the first exhaust hole. A grille is provided at the bottom of the lower flange, and a first connecting column for cooperating with the sealing member is provided at the center inside the grille. A connecting groove for cooperating with the snap button is provided at the bottom of the upper flange. In the sealed state, the snap button is pressed tightly on the sealing member under the action of the auxiliary member, so that the sealing member is pressed tightly against the first exhaust hole to achieve sealing. In the exhaust state, the snap button bounces away from the first exhaust hole under the action of the auxiliary member, releasing the sealing member to enable the first exhaust hole to exhaust.

[0004] As an improvement, the snap button includes a columnar button body. The button body is a hollow structure with an open bottom. A first clamping head is provided circumferentially outward at the top of the button body, and a elastic ring is provided circumferentially outward at the bottom. A second clamping head is provided at one end of the elastic ring away from the button body.

[0005] As an improvement, limiting columns are respectively provided at the connection between the elastic ring and the button body.

[0006] As an improvement, the inner diameter from the second clamping head to the center of the button body is greater than the inner diameter from the inner end face of the connecting groove in the base to the center of the base, so that when the snap button is connected to the base, the elastic ring is bent into an arc shape under the action of the elastic force.

[0007] As an improvement, the sealing member is an umbrella-shaped member that warps towards the snap button. A second connecting column corresponding to the first connecting column is provided at the center of the sealing member. The second connecting column is a hollow structure with an open bottom.

[0008] As an improvement, the inner diameter of the upper flange is larger than the inner diameter of the first exhaust hole, and a seal placement groove is further provided along the outer edge of the first exhaust hole.

[0009] As an improvement, the auxiliary member includes a cylindrical connecting member, an auxiliary surface provided on the upper part of the connecting member, a clamping ring provided on the lower part of the auxiliary surface, and a limiting ring provided at the bottom of the connecting member. The connecting member is a hollow structure that penetrates up and down, and a chute corresponding to the second clamping head is provided on its inner side.

[0010] As an improvement, the inner diameter from the chute to the center of the connecting member is smaller than the inner diameter from the second clamping head to the center of the buckle body.

[0011] As an improvement, a second exhaust hole is provided on the auxiliary surface.

[0012] As an improvement, the outer diameter of the auxiliary surface is the same as the outer diameter of the upper flange, and the outer diameter of the clamping ring is the same as the inner diameter of the upper flange.

[0013] After adopting the above structure, the present invention has the following advantages: The present invention pulls the elastic buckle through the auxiliary member to ensure the internal and external connection of the air valve, realize the direct discharge of gas, simplify the traditional sealing method of covering the air outlet with a lid for the air valve, is convenient for assembly and use, and will not cause air leakage.

A first exhaust hole 5 runs through the center of the base 1. Upper flanges 6 and lower flanges 7 are respectively provided outward at the upper and lower ends of the first exhaust hole 5. A grille 8 is provided at the bottom of the lower flange 7. A first connecting column 9 cooperating with the seal 2 is provided at the center inside the grille 8. A connecting groove 10 cooperating with the elastic buckle 2 is provided at the bottom of the upper flange 6. In the sealed state, the elastic buckle 3 is pressed against the seal 2 under the action of the auxiliary member 4, so that the seal 2 is pressed against the first exhaust hole 5 to achieve sealing. In the exhaust state, the elastic buckle 3 bounces away from the first exhaust hole 5 under the action of the auxiliary member, releasing the seal 2 to enable the first exhaust hole 5 to exhaust.

[0037] As a preferred implementation scheme of this embodiment, the elastic buckle 3 includes a cylindrical buckle body 3.1, and the buckle body 3.1 is a hollow structure with an opening at the bottom. A first clamping joint 3.2 is circumferentially provided outwardly at the top of the buckle body 3.1, and an elastic ring 3.3 is circumferentially provided outwardly at the bottom. A second clamping joint 3.4 is provided at one end of the elastic ring 3.3 away from the buckle body 3.1.

[0040] As a preferred implementation scheme of this embodiment, the sealing member 2 is an umbrella-shaped member tilted toward the elastic buckle direction, and a second connecting column 11 corresponding to the first connecting column 9 is provided at the center of the sealing member 2. The second connecting column 11 is a hollow structure with an opening at the bottom.

[0041] As a preferred implementation scheme of this embodiment, the inner diameter of the upper flange 6 is larger than the inner diameter of the first exhaust hole 5 , and a sealing member placement groove 12 is further provided on the outer edge of the first exhaust hole 5 .

[0046] When the present invention is implemented, first, the seal is installed on the first connecting column in the base, then the elastic buckle and the auxiliary member are buckled through the docking of the first card joint and the chute, and then the outer edge of the elastic ring is pressed into the connecting groove in the base through the second card joint; since the inner diameter from the second card joint to the center of the buckle body is greater than the inner diameter from the inner end face of the connecting groove in the base to the center of the base, when the elastic buckle is connected to the base, the elastic ring is bent into an arc shape under the action of elasticity; when deflation is required, the elastic buckle is pulled upward through the auxiliary member, so that the elastic buckle bounces upward. At this time, both sides of the air valve are communicated through the first exhaust hole, and the gas can be discharged from the first exhaust hole towards the auxiliary member; when the exhaust is over, by pressing the auxiliary member, the elastic buckle is squeezed downward. At this time, the seal is tightly connected to the first exhaust hole under the squeezing action of the elastic buckle, so that the first exhaust hole is closed, realizing the sealing of the air valve. A cover body can also be provided on the auxiliary member to cover the upper surface of the auxiliary member.
