Description

Rotary Vacuum Pumping Devices

The present invention relates to a rotary vacuum pump device which is operated manually, and more particularly, by converting the reciprocating linear motion of the vacuum pump consisting of a cylinder and a piston into a rotational motion to make the vacuum operation more smooth and convenient. It is an invention for increasing.

A general manual vacuum pump requires more force to operate a piston in a cylinder because the internal vacuum pressure of the vacuum container increases with time of operation.

It is also inconvenient to operate the piston against the suction port attached to the hose in the vacuum vessel, but it is to be avoided when more force is required.

In addition, the electric vacuum pump function does not require any force in use because it can easily operate the vacuum, but the negative image of the vacuum product that is expensive compared to the sealed container due to noise and vibration by the pump motor while plugging in the electric cord. It is true

Due to such inconvenience in use, the popularization or activation of vacuum containers is not made by blocking the dissemination of vacuum containers, but rather, the increasing price of vacuum vinyl bags is gradually increasing.

In most cases, vacuum plastic bags can be used only once or several times, which means that there are many waste elements and the amount of waste increases.

Therefore, there has been a great demand for improvement of the convenience of vacuum operation even for the popularization of vacuum containers that can be used until they are damaged.

In order to meet the market trend, Korean Air Patent No. 10-0849536 has proposed a closed container in which a vacuum pump is integrated, and Korean Patent Application Publication No. 10-2009-0114638 discloses a manual pump air discharge. A vacuum vessel having a means has been proposed, and in the Republic of Korea Patent No. 10-0969703, a vacuum pump and a vacuum vessel having the same have been proposed.

Despite various invention activities for activating the vacuum container according to the prior art, the convenience of the vacuum function has not been greatly improved.

In other words, by providing a vacuum pump integrally with the vacuum vessel to improve the ease of use, but limited to some specialized vacuum vessel.

The function of the vacuum pump for easily evacuating various vacuum containers with little force was not satisfied.

The present invention has been created to solve the problems of the prior art as described above, the object of the present invention is to first convert the reciprocating linear motion to rotational motion to facilitate the operation of the vacuum pump with the least force, second The operating point of the handle of the rotating plate is as far as possible from the center to minimize the force required for the same rotational torque. Third, the application of the winding device for the vacuum suction port and the hose doubles the convenience of use. The space can be secured at the same time so that the vacuum operation by the vacuum pump and the suction port mounting of the vacuum container can be easily performed with both hands.

Vacuum pump according to a preferred embodiment of the present invention for realizing the above object is possible by mounting the crank and the spindle in a reciprocating linear motion consisting of a cylinder and a piston to convert to a rotary motion.

In order to change the operation, the crank 14 is provided at the end of the piston 15B so as to be converted into rotational motion by the reciprocating motion of the spindle 15A and the spindle 15A, and the central axis of the crank 14 is the rotating plate. It is characterized in that it is connected to the center of the A (12) and the rotary shaft 14A of the spindle 15A is eccentrically separated from the center of the rotary plate A (14) by R1 to the rotary plate A (14).

As a preferred feature of the present invention, the handle 11 is provided on the rotating plate A 12 capable of rotating the crank 14, and the handle 11 is the rotating shaft 14A of the spindle 15A on the rotating plate A 12. Is connected to the rotating plate A 12 eccentrically by a distance R2 further than the connected distance R1 to reduce the rotational force.

As a preferred feature of the present invention, the rotary plate B 21 and the lower plate 22 are provided as a means of winding the suction port 25 and the hose 24 for vacuuming the vacuum container 40. It is equipped with the roller 26 for movement and has a simple winding function.

The rotary vacuum pump device which is operated manually according to the present invention can not only reduce the rotational force as described above, but also can easily operate the vacuum while rotating with one hand, thereby allowing the housewife who handles the vacuum container mainly in the kitchen. Make it easy to use

In addition, the vacuum pump equipment is designed to be conveniently placed on the dining table or the sink because it provides a space for placing and using the vacuum container, and it is easy to collect with the vacuum container from the refrigerator because it can be operated with both hands.

Since it is not necessary to use a disposable vacuum plastic bag, not only waste can be prevented, but also the mass production of waste can be said to be environmentally friendly. It is expected to contribute to the promotion of the supply of vacuum containers by making them available until they are broken.

Since the vacuum container prevents the evaporation or deterioration of moisture rather than the sealed container, it is predictable that the popularization of the vacuum container will be possible if only the ease of use of the vacuum operation can be improved.

Therefore, according to the present invention, if the housewives can be reduced to a minimum and food can be kept fresh, the vacuum product business is expected to expand.

After drawing out from the inlet holder 34 and seating the inlet 25 on the vacuum valve of the vacuum container 40, the operation of vacuuming by rotating the handle 11 of the rotating plate A (12) is illustrated.

With reference to the drawings will be described in detail the configuration of the rotary vacuum pump device of the present invention.

The configuration of the detailed parts of the functional assembly 10 for converting the linear motion of the vacuum pump composed of the piston 15B and the cylinder 17 into the rotational motion will be described.

The functional assembly 10 has a cylinder 17 and a piston 15B constituting a vacuum pump, and at one end of the piston 15B is vacuumed by a piston head 16, a piston ring 16A and an air groove 16B. It serves to extrude air from the container 40 and mounts the spindle 15A at the other end of the piston 15B so that the linear motion is converted into the rotational motion by the crank 14 and the rotational shaft 14A.

At this time, the rotary ring 18 at the end of the cylinder 17 is configured to be easy to rotate left and right, and the center of rotation and the axis of rotation 14A of the crank 14 are connected to the center and the outer periphery of the rotating plate A 12, respectively. The crank 14 is formed to be interlocked by the rotation operation of the handle 11 mounted on the upper portion of the rotating plate A 12.

At this time, the support A (13) serves to support the rotation center axis of the crank 14 to facilitate rotation.

Next, the components of the inlet assembly 20 having a winding function of the inlet 25 and the hose 24 will be described in detail.

The suction inlet assembly 20 has a rotating plate B 21 and a rotating lower plate 22 to which the hose 24 can be wound, and a roller 26 and a roller pin 27 for smooth movement of the hose 24 are left and right 2. Rotating projections 28 formed on the upper portion of the rotating plate B (21) serves to facilitate the rotation and the support B (23) so that the rotation ring 18 of one end of the cylinder 17 is smoothly rotated Play a supportive role.

Finally, the components of the exterior part 30 forming the outer body according to the present invention will be described in detail.

The exterior part 30 is composed of an upper case 31 and a lower plate 32 forming a bottom of the outer body at the upper part of the outer body, and an inlet holder 34 is formed at the center of the side surface of the upper case 31 and the lower plate 32. ) Is assembled with a fixing bracket 33 for fixing the upper case 31.

The assembly correlations of the components of the functional assembly 10, the suction inlet assembly 20, and the exterior portion 30 described above are described in detail in FIG. 2.

Next, the operation state of the components described above will be described in detail with reference to the operation state.

Such an operation state is illustrated in FIGS. 3, 4, and 6 and will be described with reference to this drawing.

As shown in FIG. 3, when the handle 11 mounted on the upper portion of the rotating plate A 12 is grasped and rotated, the rotating plate A 12 is positioned at a position of "1" before the operation based on the rotation center axis of the crank 14. The rotating shaft 14A which has been placed is rotated to the position of "2". At this time, the spindle 15A and the piston 15B, which are connected to the rotating shaft 14A, compress the air inside the cylinder 17 of the piston head 16.

In addition, as the rotation shaft 14A rotates, the rotation ring 18 rotates by "θ". This compression process proceeds to the position "3" and the position of the piston head 16 is also moved to the position "3".

Referring to the piston head 16 shown in Figure 5 with respect to the discharge process for the compressed air to move the piston head 16 in the compression direction, the piston ring 16A to move in the opposite direction of compression As a result, the hole of the air groove 16B is opened. At this time, the piston head 16 is formed so that the compressed air is discharged in the opposite direction of compression through the air groove 16B.

When the rotating shaft 14A rotates from the position of "3" to the position of "4", the cylinder head 16 moves by R1 from the compression direction to the vacuum direction. As the rotary shaft 14A rotates, the cylinder 17 and the piston 15B and the spindle 15A rotate about the rotary ring 18 by "θ".

5, the piston ring 16A moves in the compression direction while the piston head 16 moves in the opposite direction of compression, while the cylinder 17 is moved from the vacuum vessel 40. Vacuum operation is performed while sucking air through.

At this time, since the piston ring 16A is sealed irrespective of the air groove 16B, a vacuum operation is already known and a detailed description thereof will be omitted.

This process is repeated while rotating shaft 14A rotates from the " 1 " position to the " 4 " position such that the vacuum container 40 is in a vacuum state. That is, while the rotation diameter 2 * R1 of the rotating shaft 14A becomes the stroke distance L of the piston head 16, it vacuum-operates.

In FIG. 4, such an operation state is well specified in a three-dimensional perspective view, and the rotational dynamics thereof is also shown.

That is, the higher the internal vacuum pressure of the vacuum vessel 40, the more the vacuum process of the cylinder head 16 enters the force. For this reason, conventional hand vacuum pumps have been inconvenient to use, and thus the use of vacuum containers has not been activated.

The internal vacuum pressure of the vacuum vessel 40 and the frictional force of the piston head 16 act as the rotation torque T of the crank 14 and the rotation shaft 14A.

At this time, the rotation torque T may be expressed as follows.

T = R1 × F1

Since the rotation torque T is determined by the internal vacuum pressure of the vacuum vessel 40 and the frictional force of the piston head 16 as described above, in order to minimize the rotational force F2 actually required to be applied to the handle 11, R1 is as small as possible and R2. It will be possible to mount large.

That is, it can be displayed as follows.

T = R1 × F1 = R2 × F2

R1 <R2

F1 ＞ F2

6 shows a winding operation state of the hose 24.

In more detail, when the rotary projection 28 on the upper portion of the rotating plate B 21 is pushed by hand, the inlet 25 is returned to the inlet holder 34 after the vacuum operation is completed. Such a function is set for convenience of use, and if it does not function like this, it provides a space for placing the vacuum container 40 so that the vacuum pump and the container can be placed at the same time and easily used by both hands.

At this time, the end of the hose 24 which is connected to the cylinder 17 for the winding function is not to be interfered by the rotation of the rotating plate B 21 or the lower plate 22 is a natural structure, so a detailed description thereof will be omitted. do.

On the other hand, the present invention is not limited to the embodiments described, it is possible to change the application area used, and various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-evident to those who have.

Therefore, such modifications or variations will have to belong to the claims of the present invention.
