Abstract

The present invention relates to a vacuum pump device which makes a cam shaft to make a vacuum container, a vacuum pack, etc. through the pumping while eccentrically rotating from side to side and eccentrically ascending and descending upward and downward with the cam motion of a cam shaft by motor rotation. Especially, a rotary plate (20) which is axis-installed on a motor axis (10) of a driving motor (M) and the upper side of the cam shaft (30) are installed to be eccentrically connected. A bellows tube (60) is connected and installed to a space between the lower side of the cap shaft (30) and a pumping operating room (50). The bellows tube (60) is vacuum-operated by being compressed, expanded, and pumped when the cam shaft (30) is eccentrically rotated with cap operation while ascending and descending upward and downward. Thus, service life is long unlike a traditional piston type since the generation of abrasion is less and vibration noise can be remarkably reduced. Moreover, the present invention provides marketability by preventing the vacuum container, the vacuum pack, etc. from being polluted by not using a piston lubricant like the traditional piston type.

Description

Technical Field [0001] The present invention relates to a vacuum pump device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum pump device used for pumping a vacuum container or a vacuum pack by pumping the camshaft vertically up and down together with a cam shaft rotatably driven by cam rotation of the cam shaft by motor rotation, , The piston is pumped by the cam of the camshaft. As the bellows tube connected to the camshaft is pumped while compressing and expanding, the camshaft moves up and down eccentrically to the left and right. And thus the vibration noise is remarkably reduced. In addition, the present invention relates to a vacuum pump apparatus for preventing the problem of contamination of a vacuum container, a vacuum pack or the like with a lubricating oil without using a piston lubricating oil as in the conventional piston type.

BACKGROUND ART [0002] In recent years, the use of vacuum containers, vacuum packs, and the like for vacuum or compression storage of foods and other various items has increased rapidly.

Such a vacuum container, a vacuum pack, or the like is provided with a vacuum valve for inflow and outflow of air, and the internal air is taken out to the outside through the valve and stored in vacuum or compression.

At this time, a vacuum pump device is used to extract the internal air such as the vacuum container and the vacuum pack.

As shown in FIGS. 1 and 2, the conventional vacuum pump apparatus has a rotary plate 2 mounted on a motor shaft of a drive motor M and an upper portion of the camshaft 3 in an eccentric position And the lower portion of the camshaft 3 is connected to the piston 6 of the lower pumping actuation chamber 5 so that the camshaft 3 is biased by the rotation of the drive motor M in a cam- So that the piston 6 is pumped in the lower pumping operation chamber 5 to operate as a vacuum by suction and discharge of air.

At this time, the suction operation port, which is hose-connected to the suction port 5a of the pumping operation chamber 5, is brought into close contact with a vacuum valve such as a vacuum container or a vacuum pack so that the internal air is discharged to the outside.

However, in the conventional vacuum pump apparatus, as shown in FIGS. 2 and 3, the cam shaft 3 is moved up and down by the rotation of the rotary plate 2 provided on the motor shaft of the drive motor M, The camshaft 3 is positioned vertically to the center of the piston 6 at the upper and lower positions of the rotary plate 2 but at the eccentric position of the camshaft 2 in the center left and right of the rotary plate 2, The piston 6 is vertically moved upward and downward while being eccentrically and horizontally eccentrically rotated in the pumping operation chamber 5 so that the side surface of the piston 6 is not moved vertically in the pumping operation chamber 5, And the abrasion and friction are severely generated.

That is, when the piston 6 is pumped in the pumping operation chamber 5, abrasion and friction are severely generated, resulting in a decrease in the durability of the piston 6, as well as a drastic operation noise of the piston 6.

In addition, the conventional vacuum pump apparatus uses lubricating oil to smoothly pump the piston 6 in the pumping operation chamber 5, and the lubricating oil leaks to the outside during use to contaminate the vacuum container and the vacuum pack.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a vacuum cleaner which is used to vacuum a vacuum container and a vacuum pack by pumping by a cam action of a cam shaft by motor rotation, As the piston is pumped in operation, the bellows tube connected to the cam shaft is pumped while compressing and expanding. As a result, the cam shaft is raised and lowered eccentrically to the left and right. Thus, unlike the conventional piston type, friction life and wear are reduced, The vibration noise is remarkably reduced and the piston lubrication oil is not used as in the conventional piston type so that the problem of contamination of the vacuum container and the vacuum pack with the lubricating oil can be prevented and the commerciality can be excellently provided.

According to the present invention, a rotating plate provided on a motor shaft of a driving motor and an upper portion of a camshaft are connected in an eccentric manner so that the camshaft rotates eccentrically by cam action by the rotational driving force of the driving motor, And a pneumatic operation is performed through the intake port and the exhaust port of the pumping operation chamber in a pumping operation in the operation chamber, wherein the bellows tube is connected between the lower portion of the camshaft and the pumping operation chamber, The bellows tube is compressed and expanded while being pumped up and down to operate in a vacuum state.

The bellows tube of the present invention is characterized in that the bellows tube is formed in a trapezoidal shape having a narrower upper diameter and a wider lower diameter.

The present invention is used for pumping a vacuum chamber, a vacuum pack, etc. by pumping by a cam action of a cam shaft by a motor rotation, and the pumping operation of the piston as in the prior art by the cam action of the cam shaft, Since the tube is pumped while compressing and expanding, the cam shaft is raised and lowered eccentrically to the left and right. Thus, unlike the conventional piston type, friction and wear are less likely to occur and the service life is long and the vibration noise is significantly reduced. The vacuum chamber, the vacuum pack, and the like are contaminated with the lubricating oil.

That is, the vacuum pump device is improved in merchantability and excellent in use satisfaction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The vacuum pump apparatus 100 of the present invention is used to operate in a vacuum while being controlled by an on / off switch 5 provided inside the main body 2 as shown in FIGS.

The vacuum pump apparatus 100 according to the present invention includes a rotary plate 20 provided on a motor shaft 10 of a drive motor M and an upper portion of the camshaft 30 eccentrically connected to the rotary shaft 20, The camshaft 30 rotates eccentrically in the camming operation by the driving force so that the camshaft 30 is pivoted upward and downward while moving up and down in the lower pumping operation chamber 50 so that the suction port 51 and the discharge port 52 of the pumping operation chamber 50, So that the air is sucked and discharged by the air.

Particularly, a bellows tube 60 is connected between the lower portion of the camshaft 30 and the pumping operation chamber 50 so that the camshaft 30 is eccentrically turned by the cam action, (60) compresses and expands while being pumped to operate in a vacuum.

The upper portion of the bellows tube 60 is hermetically coupled to the inside of the bellows tube 60 with a fixing member while the lower end of the bellows tube 60 is inserted, And are configured to be connected and connected.

In addition, the bellows tube 60 may be formed in a trapezoidal shape having a narrower upper diameter and a wider lower diameter, and the wrinkle portion 65 may be formed as a whole or may be limited to a central portion as shown in the drawing .

Reference numeral 70 denotes a suction operation port connected to the suction port 51 of the pumping operation chamber 50 by a hose 75. [
