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

FIG. 1 is a perspective view showing an overall shape of an electronic device fine dust cleaner according to the present invention, which is composed of a dust cleaner 100 and a cleaner main body 200.

First, a dust cleaning gun 100 according to the present invention will be described.

The dust cleaning gun 100 has a suction port and a medicine spray hole formed on the front surface thereof and has a shape of an air gun having a handle formed in the direction of the lower surface of the rear surface. The dust cleaning gun 100 serves to simultaneously perform dust suction and drug spraying in the inner corner of the electronic device, (110), and a medicine sprayer (120).

The dust suction device 110 supports the dust cleaning gun 100 as a whole and turns the main body of the vacuum cleaner ON or OFF according to the pulling of the pull lever formed at the front of the handle to absorb the dust.

It consists of an inhaler body 111, a dust suction tube 112, and a pulling lever 113.

The inhaler body 111 supports the dust inhaler 110 and is formed to penetrate from the front surface coupled with the dust suction pipe 112 to the lower surface of the handle coupled with the dust suction hose 210.

The dust suction pipe 112 is formed in a hose shape coupled to the front and flexibly flexes according to the working environment and adjusts the suction direction, and serves as a suction port for directly inserting the dust suction pipe 112 into the gap of the electronic device and sucking the fine dust.

This allows the coupling portion 112a, which is threaded along the periphery, to be inserted into the inhaler body 111 for stable connection.

The pulling lever 113 is formed to be spaced apart from the front of the handle of the inhaler body 111 and controls the limit switch 113a connected to the cleaner main body through pulling and returning to simultaneously turn on and off the suction and moisture generation .

The limit switch 113a includes an upper limit switch 113a formed on one upper side of the upper portion of the inhaler body and a lower limit switch 113a formed on the upper portion of the pull lever. When the pull lever 113 is pulled, When the suction lever 113 is returned, the moisture generating device and the suction motor of the cleaner body are turned off and the suction passage is closed.

This allows the suction force to be easily controlled to selectively suck only the portion requiring dust suction, and after the dust suction is completed, the moisture generator and the suction motor are turned off to prevent unnecessary power consumption.

The medicament injector 120 is coupled to the upper end of the dust inhaler 110 and injects the medicament 2 in a spray form through the pressure generated by the piston motion of the compression pump 123 formed at the rear end.

It is composed of a medicine spraying body 121, a medicine spraying pipe 122, a pressure device 123, a compression piston 124, a medicine container 125 and a medicine suction pipe 126.

The medicament injection body 121 supports the entire medicament injector 120 and has a medicine spraying part 121b extending from the front surface to the medicine suction pipe 124b and a conduit through which the compression pump 123 can reciprocate is formed The pressure rising portion 121a penetrating from the rear surface to the air injection pipe 124a is separated by the partition wall and the piping support case 121c is opened so that the chemical suction pipe 124b and the air injection pipe 124a are not exposed to the outside. Is formed.

The medicine spraying tube 122 is connected to the front surface of the medicine spraying body 121 and is spaced apart from the upper end of the dust suction tube 112 and is supplied with a special medicine solution in the form of a tube having a porous discharge port 122a formed on the inner surface thereof It plays a role of spraying.

This means that the injection nozzle should be positioned so that the injection nozzle faces the front when necessary, and when it is not used, the injection nozzle should be rotated 180 ° to keep it folded.

When the medicine spraying pipe 122 is positioned so as to face the front, it is formed so as to protrude from the dust suction pipe 111, so that the medicine injected in the state where the dust suction and the medicine spraying are simultaneously performed can not be sprayed into the inside of the device, To prevent inhaling.

The compression pump 123 is located on the rear surface of the medicine injection body 121 and is in the form of a piston to increase the pressure of the pressure rising part 121a by reciprocating movement.

Here, the relatively high pressure air is pushed into the medicine storage container 124 through the air injection pipe 124a formed at the lower end of the pressure rising part 121a to increase the pressure.

As a result, the medicine stored in the medicine storage container is raised to the medicine suction pipe and the pressure is applied so that the medicine can be injected.

The medicine storage container 124 is a cylindrical storage container formed at the lower end of the medicine injection body 121. The medicine storage container 124 is connected to the pressure rising part 121a through the air injection pipe 124a, And supplies the medicine to the medicine spraying unit 121b by a pressure difference. The air injection pipe 124a connected to the lower end of the pressure generating unit 121a, And a medicine suction pipe 124b connected to the lower end of the medicine spraying unit 121b is inserted and hermetically coupled to the lower end of the pipeline support case 121c.

The upper portion of the air injection pipe 124a is coupled to the lower end of the pressure generating portion 121a and the lower portion of the air injection pipe 124a is coupled to the upper end of the medicine storage container 124, As shown in FIG.

Here, the medicine suction pipe 124b is connected to the lower end of the medicine spray part 121b at the upper part and is contained in the medicine contained in the medicine storage container 124 to serve as a pipe for supplying the medicine to the medicine spray part 121b , Which serves as a pipe for raising the pressure of the medicine storage container 124 due to the high pressure air injected into the air injection pipe 124a and supplying the medicine to the medicine spraying part.

At this time, the medicine (2) stored in the medicine storage container (124) is used as an exclusive medicine for dust removal or cleaning of the electronic device, and has high evaporation ability in the air which does not damage the electronic product. .

The injection shutoff valve 125 is connected to a valve plug 125a inserted in the upper end of the medicine suction pipe 124b in the form of a valve formed on the left side of the medicine injection main body 121 to open and close the outlet of the medicine suction pipe, It plays a role.

5, when the injection shutoff valve 125 is raised to the upper end, the valve plug 125a is lowered, and the upper end of the chemical suction pipe is closed to block the chemical rising to the chemical spraying part 121b, As shown in FIG. 6, when the injection shutoff valve 125 is lowered, the valve stopper 125a rises and the upper end of the medicine suction pipe is opened to lift the medicine, and the medicine is sprayed through the medicine spraying part and the medicine spraying tube .

If the pressure inside the medicine storage container 124 drops below a predetermined pressure, the medicine is not sprayed even if the valve is opened, so that the pressure inside the medicine storage container does not drop below a certain pressure through the reciprocating movement of the compression pump .

Next, the cleaner main body 200 according to the present invention will be described.

The cleaner main body 200 collects the fine dust sucked by the dust cleaner and purifies and discharges the sucked air such as dust. The cleaner main body 200 includes a dust suction hose 210, a dust suction case 220, And a power supply unit 230.

The dust suction hose 210 is a hose formed between the dust cleaner 100 and the cleaner main body 200 to transmit the suction force of the cleaner main body to the dust cleaner, It serves to deliver it to the cleaner body.

The dust absorbing case 220 totally supports the cleaner main body 200 and controls the dust cleaner and the moisture generating device through the suction intensity switch 220a and the moisture generating switch 220b formed at the upper end to purify the sucked air And discharges it to the outside, and collects inhaled fine dust and foreign matter.

Here, the suction strength switch 220a has a sliding switch shape formed at the upper end of the cleaner main body, and serves to control the suction force by turning the operation of the suction motor 225 on or off and controlling the rotation speed in steps.

At this time, the rotation speed is controlled step by step because it is sensitive to impacts depending on the apparatus, or suction is carried out at a low pressure when a small amount of dust is accumulated, and when a device or dust having a relatively strong impact is piled up, It is for use with different suction pressure depending on the situation.

Here, the moisture generating switch 220b controls the amount of moisture generated by turning on / off the operation of the moisture generating device 221 and controlling the current flowing in the vibrator step by step, in the form of a sliding switch formed on the upper end of the cleaner main body .

Here, even if the moisture generating switch 220b is turned on, the moisture generating device 221 is not operated when the suction intensity switch 220a is turned off, so that the moisture is sprayed only when the suction is progressed.

It is composed of a moisture generation device 221, a water bottle 222, a dust box 223, a filter 224, a suction motor 225 and an exhaust port 226.

The moisture generating device 221 forms a moisture spray nozzle in a direction diagonally opposite to the upper end of the dust suction tube and facing the dust inlet of the dust suction hose, and discharges fine water molecules to the inhaled fine dust. The spray nozzle 221a is positioned at the upper end to prevent the foreign matter from blocking the nozzle inlet and water molecules are sprayed in the direction of the inclined lower end of the dust bin to collect the moisture before the fine dust and the foreign matter reach the filter, .

This is a humidifier type of ultrasonic method, and the water is made into a mist shape and then sprayed to the moisture spray nozzle 221a through a small fan.

The water bottle 222 is formed on a side surface of the moisture generating device and serves to supply moisture to the moisture generating device.

This is because the upper end of the cleaner body is formed in a transparent form so that the detachable handle is formed at the upper end thereof to facilitate detachment and attachment and to confirm the amount of the built-in water.

'형상으로 먼지흡입기에서 흡입된 먼지 및 이물질을 저장하는 역할을 한다.The dust container 223 is located at the lower end of the moisture generating device,

'Shape, it serves to store dust and foreign matter sucked from the dust inhaler.

This forms a sloped surface in the opposite direction to the filter 224 so that dust and debris can block the bottom of the filter to reduce the efficiency of the filter and shorten its life.

The filter 224 is formed on the rear surface of the dust container to filter out fine dust and floating harmful substances contained in the sucked air and to pass the purified air through the filter 224. A removable handle is formed on the side surface of the cleaner main body, It is easy to attach and detach due to cleaning and replacement.

In the present invention, the filter 224 may be made of any one selected from a polyester filter, a polyurethane foam filter or a HEPA filter in an extract solution for 5 to 10 minutes, A filter manufactured by drying for 20 to 24 hours,

The ginseng extract is prepared by adding ginseng to water having a weight of 10 to 15 times and shaking the extraction container connected with the cooler at 90 to 95 ° C for 2 to 4 hours to obtain a primary extract, Weight water is further added thereto and heated at 90 to 95 ° C for 1 to 2 hours to obtain a secondary extract. The primary extract and the secondary extract are mixed and then filtered to obtain a dry weight of 0.3 to 0.35 g / Ml for 5 to 10 minutes, and dried at room temperature for 20 to 24 hours.

One of the indicators indicative of the characteristics of the filter 224 is pressure loss, which is directly related to the air permeability of the filter. If the air permeability is good, the pressure loss is small. If the air permeability is bad, the pressure loss is large.

Since the polyester has a high air permeability of 265.2, the pressure loss is small, but the polyester has a disadvantage in that it is somewhat deteriorated in terms of efficiency.

The high efficiency specific air (HEPA) fiter means that the particulate DOP (Dioctyl phthalate) particles having a size of 0.3 탆 are used and have a dust collection efficiency of 99.97% or more by a filter performance evaluation under a condition of a standard flow rate of 5 cm / sec.

As a HEPA class filter, the folded micro-electrostatic filter is fabricated from micro-fibers having a diameter of about 0.5 to 1.5 micrometers to fibers having a diameter of 20 to 30 micrometers and is useful for fine dust collection by applying an electrostatic force. Bending micro- ) Is scattered and adhered in a fibrous form to be made into a sheet-like fiber of glass fiber, which is useful for fine dust collecting.

In the present invention, a ginseng extract is used in order to impart antimicrobial properties to a filter having good breathability and being resistant to moisture.

That is, the antibacterial property of the filter can be enhanced by supporting the filter on the extract of Gossam gypsum and drying it.

When the holding time is less than 5 minutes, the antibacterial property of the filter is deteriorated. When the holding time exceeds 10 minutes, the antibacterial property does not change much, so that the holding time is limited to 5 to 10 minutes. When the drying time is less than 20 hours, sufficient drying is performed. If the drying time exceeds 24 hours, the drying is completely completed, which is meaningless.

When the amount of water used in the preparation of the first ginseng extract is less than 10 times the amount of ginseng, extraction is not properly performed. When the amount of water used is more than 15 times, it takes much time to extract the first ginseng extract. Is 10 to 15 times the blending ratio.

Sophora flavescens has excellent antimicrobial effect, and it has been used in insecticide, analgesic and insecticide medicines since ancient times.

The ingredients of gosam are known as alkaloid, flavonoid, flavanone, flavanol, triterpene, quinone, saponine and sapogenol.

As alkaloids, matrin, isomatrine, allomatrine, oxymatrine, kuraramin, and anagyrine were reported as isoanhydroicarine and vexibinol as flavonoids, soyasogenol B and soyasaponin I as triterpene and kushenquinone as quinones.

The flavanones were reported as kurarinol, kushenol A, B, E, F, and flavanols were reported as Kushenol J, K, L,

More specifically, the manufacturing process of the antibacterial filter will be described.

The PET filter was immersed in the extract solution for 5 minutes and dried at room temperature for 24 hours to prepare an antibacterial filter.

In the extract of the ginseng extract, 5 L of water is put into an extraction flask to which a cooler is connected, and then 500 g of ginseng is administered.

The above extraction flask is placed on a heater and shaken at 90 DEG C for 3 hours to obtain a primary extract. Next, 3.5 liters of water was added to the extraction flask, and then a secondary extract was obtained for 1 hour.

The extracted primary and secondary extracts are mixed and then filtered using a filter. The extract is concentrated using a rotary evaporator, and the concentrate is concentrated to a dry weight of 0.34 g / ml.

The suction motor 225 is connected to the suction intensity switch 220a to increase and decrease the RPM according to the stepwise control and to drive the suction fan for suctioning the dust.

The exhaust port 226 is formed on the rear surface of the dust container and discharges air purified by the filter.

The power supply unit 230 is located at the lower end of the dust absorption cylinder and moves the position of the power supply cable by winding and winding the wound power supply cable so that the dust cleaner 1 can be used, It plays a role.

Hereinafter, an electronic device fine dust cleaner according to the present invention will be described.

First, the medicine is supplied to the medicine storage container, and the medicine is supplied to the lower end of the medicine injection body, and water is supplied to the water bottle to be coupled through the upper end of the cleaner main body.

Then, the suction intensity and the moisture production amount are adjusted according to the use purpose through the suction intensity switch and the moisture generation switch of the cleaner main body.

Then, the compression pump is pulled backward and then reciprocated to push it.

At this time, the air compressed in the pressure generating unit moves to the medicine storage container through the air inlet tube, and a force for pushing the medicine from the upper end to the lower end is generated, and the medicine is raised through the medicine suction pipe.

Next, take the dust suction pipe inlet to the dust removal area inside the electronic device, pull the pull lever backward, and turn on the suction motor and the moisture generator.

At this time, the suction force generated by the rotation of the suction motor is sucked through the dust suction hose and the dust suction device, and the moisture generated in the moisture generating device is sprayed toward the dust inlet and sucked in the fine dust And is collected in the dust container.

Here, the fine dust and foreign matter not collected are collected secondarily through the filter.

Subsequently, when the dust removal inside the electronic device is completed or when the suction is stopped, the drawn pull lever is released to drop the contact of the limit switch so that the suction motor and the moisture generator are turned off.

At this time, the rotation of the suction motor is stopped, the suction force is removed, and moisture generation is stopped.

Then, the injection shut-off valve is rotated in the lower direction to open the valve stopper and is raised to the medicine suction pipe by the pressure of the medicine storage container and discharged through the medicine spray pipe.

At this time, the raised medicine passes through a narrow hole of a porous discharge port formed on the front surface of the medicine discharge pipe in a relatively wide space of the medicine discharge part, and the medicine is discharged and sprayed. When the air pressure inside the medicine storage container is lowered, And the pressure is raised to prepare the medicine injection.

Then, when the injection of the part requiring the medicament injection is completed or when the injection is stopped, the spray shutoff valve is rotated in the upper direction so that the valve cap closes the upper end of the medicament suction pipe to shut off the medicament.

Finally, when the suction of the dust inside the electronic device and the injection of the medicine are finished, the suction intensity switch and the moisture generating switch are turned off, and the dust container is detached and the collected fine dust and foreign matter are removed.
