Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cylinder driving apparatus for an external disinfecting apparatus,

The present invention relates to a cylinder driving apparatus for an external disinfecting apparatus, and more particularly, to a cylinder driving apparatus for driving a cylinder of an external disinfecting apparatus having a cylinder for disinfecting a disinfecting cartridge and an operating pin provided outside the chamber.

Generally, the disinfecting apparatus can be various kinds of disinfection apparatus such as a disinfecting apparatus for vegetables and fruits, a disinfecting apparatus for food, an air disinfecting apparatus for indoor space, a disinfecting apparatus for kitchen apparatus, and a disinfecting apparatus for medical equipment. Depending on the disinfection method, various types are known, such as an ultraviolet sterilizer, a high-pressure sterilizer, a chemical gas sterilizer, and an ozone sterilizer.

Conventionally, disinfection is indispensable because medical equipment used in emergency vehicles and hospitals of fire stations are used by many people. Conventionally, a sterilizer of high pressure steam type or an EO gas sterilizer is mainly used for disinfecting medical equipments.

1 is a cross-sectional view showing an example of a conventional disinfector of the EO gas sterilization method. A conventional EO sterilizer includes a chamber 1, a shelf 2 provided inside the chamber 1 for accommodating medical instruments, a door 3 installed on the front surface of the chamber 1, A vacuum pump 4 connected to the interior of the chamber 1 to maintain the interior of the chamber 1 in a vacuum state and a cylinder 5 for closing the EO cartridge 6 inside the chamber 1 .

Such a conventional EO gas sterilizer disposes EO gas by ejecting a connection hole to the EO cartridge 6 when the EO cartridge 6 is used. In order to prevent the EO gas from being ejected to the outside due to toxicity and explosiveness of the EO gas, A cylinder 5 for providing a connection hole is provided inside the chamber 1.

The vacuum pump 4 is operated to vacuum the inside of the chamber 1 and then the cylinder 5 inside the chamber 1 is operated to blow up the EO cartridge 6 to disinfect the chamber 1, And the medical instruments housed therein were disinfected.

However, the EO gas sterilization method has the advantage of sterilizing microorganisms of all kinds and not damaging the instruments or articles to be disinfected, but it is very toxic and explosive so that the cylinder (5) installed in the chamber (1) Frequently.

Therefore, troubles frequently occur during use, breakage of parts is frequent, and there is a problem that maintenance is difficult, for example, the cylinder 5 needs to be replaced.

In addition, since the cylinder 5 needs to be installed inside the chamber, there is a danger that an explosion may occur in the chamber 1 due to static electricity or sparks generated during operation of the cylinder 5, thereby causing a safety accident. In addition, since the cylinder 5 needs to be installed inside the chamber 1, it is very difficult to install the cylinder.

2, a chamber 10 in which a connection hole 11 is drilled and a disinfecting mechanism and a disinfecting cartridge 50 are housed in the chamber 10, a chamber 10 opposed to the connection hole 11, A connecting tube 20 having both ends connected to the cylinder 30 and the connecting hole 11 so as to block the communication of the inside of the chamber 10 with the outside, The disinfection cartridge 50 which is fixed to the front end of the cylinder rod 31 reciprocally moved from one side and located inside the connection pipe 20 and accommodated in the chamber 10 while being moved forward and backward by the cylinder rod 31 (See Korean Patent Registration No. 10-1309229), and an external disinfecting device including an operation pin 40 for disposal.

However, when the cylinder 30 is a hydraulic cylinder, the generation and control of the hydraulic pressure is complicated, and the size of the cylinder 30 is increased. In addition, since there are many problems such as a risk of fire due to leakage of oil and cleanliness, I never do that. The use of a pneumatic cylinder in the sterilizer causes the pneumatic cylinder 30 to be driven to break the cartridge 50 so that the operating pin 40 and the disinfection cartridge 50 are not fast enough, The operation pin 40 may be broken due to a shock.

3 is a view showing a configuration of a cylinder driving apparatus of an external disinfecting apparatus according to an embodiment of the present invention.

The cylinder driving apparatus of the external disinfecting apparatus according to the embodiment of the present invention includes a liquid supply unit 70, a flow pipe 72, a valve 74, and a control unit 76.

The liquid supply unit 70 can supply a liquid (e.g., water, mineral oil, etc.) 71 to the cylinder 30 side by using the air pressure.

A moving film 70a capable of moving up and down is provided inside the liquid supply part 70. [ Compressed air is filled in the upper space based on the moving film 70a, and liquid 71 is filled in the lower space.

The air is not limited to oxygen, and various gases such as nitrogen gas may be supplied.

In the present invention, air represents gas, and then liquid is mostly water or mineral oil (in the case of a mechanical device such as a cylinder, the type of liquid (usually called mineral oil) Lt; / RTI >

The flow pipe (72) is connected to one side of the cylinder (30) at a lower part of the liquid supply part (70). The liquid 71 is supplied to the cylinder 30 through the flow pipe 72.

The valve 74 is installed at a predetermined position of the flow pipe 72. The valve 74 controls the flow rate of the liquid 71 supplied to the cylinder 30 through the flow pipe 72 under the control of the control unit 76.

The valve 74 is regulated by the control of the control unit 76.

The control unit 76 can control the flow rate of the liquid 71 supplied to the cylinder 30 and the like. That is, the control unit 76 controls the opening value of the valve 74 to control the amount of the liquid 71 supplied to the cylinder 30, and the like.

In the embodiment of the present invention, the cylinder 30 basically drives the cylinder rod 31 with compressed air, but more specifically, by the force of the liquid 71 flowing through the valve 74, The cylinder rod 31 is driven.

3, a reference numeral 60 denotes a vacuum pump. The vacuum pump 60 is installed at one side of the chamber 10 to prevent the EO gas flowing out of the chamber 10 from being discharged to the outside of the chamber 10.

Hereinafter, the operation of the cylinder driving apparatus of the external disinfecting apparatus according to the embodiment of the present invention will be described. FIG. 4 is a view for explaining the operation of the cylinder driving apparatus of the external disinfecting apparatus according to the embodiment of the present invention, showing an initial state before the cylinder is driven. 5 is a view for explaining the operation of the cylinder driving apparatus of the external disinfecting apparatus according to the embodiment of the present invention, and shows a state after the cylinder is driven

First, the door 13 of the chamber 10 is opened to accommodate the medical instrument therein, and the disinfection cartridge 50 is housed together with the medical instruments, and then the door 13 is closed to seal the chamber 10. At this time, the sterilization cartridge 50 is housed in a position in front of the connection hole 11. This process is the same as that shown in FIG. 4 since the state before the cylinder 30 is driven. That is, as shown in FIG. 4, the liquid supply unit 70 does not discharge the liquid 71 yet.

5, when the air is supplied to the liquid supply unit 70 to drive the cylinder 30, the movement film 70a in the liquid supply unit 70 moves downward, The liquid 71 of the liquid supply portion 70 is supplied to the cylinder 30 through the flow pipe 72 and the valve 74 by the force. At this time, in order to drive the cylinder 30, the control value of the valve opening degree of the valve 74 may be preliminarily adjusted. As a result, a space for receiving the liquid and a space for supplying the gas are provided in the cylinder 30. The space is divided by the cylinder rod 31, and the liquid supplied into the cylinder 30 The cylinder rod 31 is moved.

As the liquid 71 is supplied to the cylinder 30, the cylinder rod 31 of the cylinder 30 is advanced. 5, when the cylinder rod 31 is advanced, the connecting tube 20 is contracted and the operation pin 40 fixed to the front end of the cylinder rod 31 is inserted into the disinfection cartridge 50 Lt; / RTI > The advanced operating pin 40 draws a connection hole into the disinfecting cartridge 50 to urge the disinfecting cartridge 50.

When the disinfecting cartridge 50 is blown, the EO gas is blown into the chamber 10, thereby disinfecting the medical instruments inside the chamber 10. [ At this time, since the connection hole 11 formed at one side of the chamber 10 is completely blocked by the connection pipe 20 from the outside, the EO gas is not ejected to the outside.

Then, the advanced operation pin 40 is returned to the initial position when the disinfecting cartridge 50 is blown. For example, when air, that is, gas is supplied to the cylinder 30, the cylinder rod 31 is moved backward so that the liquid 71 in the cylinder 30 flows through the flow path tube 72 and the valve 74 To the liquid supply unit 70 again. Accordingly, the moving film 70 of the liquid supply portion 70 moves upward and moves to the original position.

Of course, in order to return the cylinder rod 31 to the initial position without supplying air into the cylinder 30 as described above, the air is discharged in the reverse direction to the process of supplying the air from the liquid supply portion 70 The moving rod 70a moves upward as shown in FIG. 5, so that the cylinder rod 31 may return to its original position. However, it is also possible to separately supply air directly into the cylinder 30 to return the cylinder rod 31 to its original position. In this case, similarly to the structure of the liquid supply portion 70 shown in Figs. 3 to 5, The left and right spaces are separated from each other around the cylinder rod 31. At this time, the left side becomes a liquid storage space, the right side is divided into a gas storage space, and an air inlet is installed in the gas storage space The structure will of course be possible.

Since the cylinder driving device of the external disinfecting apparatus according to the present invention uses the force of liquid rather than advancing the operating plate 40 by air alone, the disinfecting cartridge housed in the chamber can be stably opened No sparking will occur.

In other words, it is possible to appropriately adjust the amount and flow rate of the liquid supplied to the cylinder, so that it is possible not only to prevent the occurrence of sparks at the contact surface between the operating pin and the disinfecting cartridge, but also to provide sufficient force So that the sterilization cartridge can not be pierced.

As described above, an optimal embodiment has been disclosed in the drawings and specification. While specific terms have been employed herein, they are used for the purpose of describing the invention only and are not used to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
