Description

Technology Field

[0001] The present invention relates to a vacuum valve for sucking in and closing air inside a duvet compression storage rack, and more specifically, to provide a vacuum valve for a duvet compression storage rack that facilitates easy air discharge and has excellent sealing power by improving the structure of the valve body that operates in response to the suction of a vacuum cleaner. Background Technology

[0002] Generally, items such as bedding and clothing take up a large amount of storage space, and there are storage problems such as mold easily growing due to moisture and insects attaching to them.

[0003] A vacuum compression storage rack is designed to safely and efficiently store bedding and clothing.

[0004] Typically, a vacuum storage unit is equipped with an openable and closable inlet and an air outlet for discharging air at a predetermined location on the unit. After storing bedding or clothing by opening the inlet of the vacuum storage unit, the inlet is closed, a vacuum cleaner is connected to the air outlet, and the air inside the vacuum storage unit is expelled to the outside using the suction power of the vacuum cleaner, thereby reducing the volume of the bedding or clothing.

[0005] A conventional compression pack for achieving the above-mentioned purpose comprises a valve body compressed and attached to a vinyl pack, a valve installed inside the valve body to control airflow, and a rotatable or fixed cap to prevent the valve from coming off, thereby controlling the airflow inside the compression pack through a structure in which the cap is opened to draw in internal air and the cap is fixed again.

[0006] The aforementioned conventional valve for a compression pack has the advantage of achieving perfect sealing by controlling the air inside the compression pack using a valve body and a valve and cap interposed inside the valve body.

[0007] However, there were disadvantages such as the inability to maintain perfect airtightness due to air circulation during the process of opening and closing the cap, and the need for many parts such as the valve body, rotary cap, and valve, which made the structure complex and increased manufacturing costs, resulting in a higher price.

[0008] Furthermore, it is true that removing the cap designed to prevent the valve from coming off and vacuuming the air inside the compression pack frequently results in the valve being sucked directly into the vacuum cleaner due to the absence of the cap, causing significant inconvenience during use.

[0009] This problem is that consumers have to separate the cap and compress the plastic bag, which increases the inconvenience of use. Despite the advantage of being able to effectively compress and hygienically store blankets, there is a problem in that they avoid using compression storage racks.

[0010] To resolve the aforementioned problem, Patent Registration No. 10-1083102 was proposed, which had the advantage of allowing internal air to be easily discharged as the valve was lifted upward upon air intake.

[0011] However, the aforementioned conventional patent had a problem where the center of the hole drilled in the sealing electrode and the storage rack was misaligned when the storage rack and the valve body, both made of vinyl material, were bonded and fixed, resulting in many product defects.

[0012] In addition, there was a problem in that the sealing force of the valve body was weak, resulting in a weak blocking force against airflow, and the sealing force was weak, making it difficult to maintain the compression function for a long period. The problem to be solved

[0013] The present invention has been devised to solve the aforementioned conventional problems, and the purpose of the present invention is to provide a vacuum valve for a duvet compression storage unit capable of perfect sealing even if the centers of the sealing electrode and the vinyl hole are slightly misaligned.

[0014] Another objective of the present invention is to provide a duvet compression storage rack with excellent adhesion through smooth air discharge and improved guide protrusions. means of solving the problem

[0015] The present invention, for achieving the above-mentioned purpose, is characterized by widening the sealing area of ​​a valve body fixed by a heat compression means at a predetermined position of a vacuum compression storage stand capable of compressing and storing blankets, thereby improving the problem caused by misalignment of centers, and forming a triangular protrusion on the upper surface of the valve body and a triangular groove corresponding to the triangular protrusion on the lower surface of the valve that is in close contact with the valve body so that they are tightly sealed together, thereby enabling the complete blockage of airflow.

[0016] The present invention is characterized by forming a triangular groove on the upper surface of the valve to allow for a thin thickness, thereby enabling the rubber end surface to open easily as the triangular groove folds at a predetermined angle when air is discharged. Effects of the invention

[0017] As described above, the present invention has the effect of enabling an easy bonding process even if the centers are misaligned when bonding and fixing the storage stand and the valve body.

[0018] In addition, during the opening and closing operation of the valve, the triangular groove on the valve surface folds, easily creating a gap between the valve and the valve body, which allows internal air to be drawn in more easily.

[0019] In addition, since the valve body and the valve are closely joined by the triangular protrusion and the triangular groove, this design offers excellent sealing power and has the advantage of maintaining compression for a long period of time. Brief explanation of the drawing

[0023] The present invention will be described in detail with reference to the attached drawings. First, referring to FIGS. 1 to 6, the air discharge vacuum valve of the bedding compression storage unit of the present invention comprises a disc-shaped valve body (2) fixed by a heat compression means at a predetermined position of the vacuum compression storage unit, a cylindrical guide projection (20) bent vertically downward at the center of the valve body (2), and a plurality of discharge grooves (8) formed on the outside of the guide projection (20) by radially connecting the lower end of the guide projection (20) with a partition plate (30).

[0024] A valve (10), having an upper surface formed as a flat plane and a lower side formed with a sealing portion (16) and a catch (12), is fitted into a discharge groove (8) and configured to catch on a fixing projection (22) partially formed on the outer shape of the central part of the valve body (2), so that as the valve (10) moves up and down, the sealing portion (16) is in contact with or detached from the inner wall of the discharge groove (8), thereby controlling the air inside the compression pack.

[0025] A triangular protrusion (40) is formed on the upper surface of the above-described valve body (2), and a triangular groove (42) corresponding to the triangular protrusion (40) is formed on the lower surface of the valve (10) that covers and adheres to the upper surface of the valve body (2) to block the flow of air, thereby blocking the flow of air with a double sealing force along with sealing the valve body, so as to have an excellent effect in maintaining the compression function for a long period of time.

[0026] The above-described valve body (2) has a widened sealing area to improve the problem caused by the center of the sealing electrode and the vinyl hole not aligning, and a round groove is formed on the outer edge of the valve (10) to produce a petal-shaped design, thereby providing excellent aesthetics.

[0027] In addition, a V-groove (27) is formed on the upper surface of the valve (10) to reduce the thickness, thereby creating the effect of allowing the rubber end surface to open easily when air is discharged.

[0028] The lower part of the body of the above-mentioned valve (10) is configured to form a space with a rib (46) to allow for smooth air discharge, and a fixing projection (22) is partially formed on the outer shape of the central part of the valve body (2), and a locking projection (12) is formed on the central cylindrical end surface of the valve (10) to prevent detachment due to the up-and-down movement of the rubber.

[0029] In addition, the radially formed baffles are installed in close proximity from the fixed projection to the guide projection and formed from the guide projection to the end of the valve body, thereby creating space between the stored object and the baffles to effectively draw in air from inside the compression pack.

[0030] The usage state of the present invention as described above will be explained with reference to the drawings.

[0031] First, detach the slide fastener provided in the vacuum compression storage rack, place the duvet to be stored inside, and seal the vacuum compression storage rack by pressing the slide fastener tightly.

[0032] After sealing the compression storage container, the suction port of the vacuum cleaner is positioned on the upper surface of the valve body (2), and when the vacuum cleaner is operated, the valve (10) is sucked in by the suction force of the vacuum cleaner. In this state, the upper surface of the valve (10) is separated from the upper surface of the valve body (2), and the airtight sealing part (16) rises upward, creating a space between the valve and the valve body. As a result, the air inside the compression pack flows into the vacuum cleaner along the discharge groove (8) and sucks in and compresses the air inside the compression pack.

[0033] After sucking all the air inside the compression pack, when the suction port of the vacuum cleaner is removed, the valve (10) moves downward due to the difference between the external pressure and the internal pressure, and the triangular protrusion (40) formed on the upper surface of the valve body (2) and the triangular groove (42) formed on the valve are fixed in close contact with each other, thereby blocking the flow of air and, together with the sealing of the valve body, blocking the flow of air with a double sealing force, the compression function is maintained for a long period of time.

[0034] Therefore, compression bags can be easily compressed without removing caps or performing any separate operations, and storing the compressed bags in a wardrobe allows for efficient use of space. Explanation of the symbols
