Description

Detachable sterilization apparatus of vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly to a sterilization apparatus that can be attached to and detached from the vacuum cleaner to improve the sterilization ability inside the vacuum cleaner.

In general, a vacuum cleaner is a device that sucks air containing foreign substances such as a floor or a bed, a sofa, and cleans fine dust through a filtering device installed therein.

In general, the vacuum cleaner performs cleaning by simply inhaling and filtering foreign matters using a suction nozzle running in contact with a surface such as a floor.

In general, the vacuum cleaner is made of a handle connected to the waste container through the main body and the connection pipe provided with a suction pan unit for forcibly suctioning the air inside the waste container and collect the dust and discharge to the outside, wherein The handle is connected to a suction pipe having a predetermined length so as to be rotatable to a free end of the suction pipe and moves to abut the bottom surface to suck air by the suction force of the suction fan portion, and the suction fan portion Control means for controlling the operation.

The suction plate for the vacuum cleaner is installed at the end of the suction pipe of the vacuum cleaner and is used to directly contact the surface of the object to be cleaned to suck foreign substances such as dust.

Therefore, in order to facilitate the movement of the suction plate and suction of foreign matters, the suction plate is provided with a roller and a brush in the form of a brush.

On the other hand, a number of pests and harmful bacteria, such as mites, bacteria and fungi, are breeding on the floors of homes and offices, especially carpets, and many of them are vacuumed together with dust on the floor. In addition, since the pests and harmful bacteria once inhaled continue to live in the waste container without being completely eradicated, the conventional vacuum cleaner could not be expected to have an insecticidal or sterilizing effect other than a cleaning function for sucking dust.

In addition, most of the mites have a length of 0.4 ~ 1㎜, especially those living in the home is a dust mites parasitic in the fibers, inhabit the human skin keratin as a nutrient source, feces and carcasses generated from the ticks The minute guanine harmful protein emitted from is a very important allergen, and if inhaled in the human body, it causes allergic rhinitis, asthma, and if it comes into contact with the skin, it causes various allergic dermatitis such as atopic dermatitis. There is a need to remove ticks.

The present invention is to solve the above problems by configuring a sterilization apparatus detachable to the vacuum cleaner by forming a sterilization apparatus for ozone or ultraviolet sterilization between the body and the dust inlet of the vacuum cleaner, bacteria in the dust introduced into the inside, It is an object of the present invention to provide a vacuum cleaner having a sterilizer for effectively sterilizing ticks.

Vacuum cleaner equipped with a sterilization apparatus according to the present invention for achieving the above object is to transfer the suction force generated in the main body, and the suction force generated in the main body and the suction nozzle provided by the main body using a vacuum motor A sterilization device configured to be detachably attached to a predetermined portion of the connection part and to sterilize the interior of the connection part and the body together with dust flowing into the main body through the suction nozzle, and attached to at least one side of the sterilization device. It characterized in that it comprises a blowing fan for introducing the wind into the connection portion.

Sterilization apparatus detachable to a vacuum cleaner according to the present invention has the following effects.

First, by constructing a sterilization apparatus detachable to the vacuum cleaner by the ozone or ultraviolet sterilization between the body of the vacuum cleaner and the dust inlet, it is possible to effectively sterilize the bacteria, mites in the dust flowing into the connection or the body.

Second, by attaching a blowing fan to the sterilization device can be more effectively sterilized the connection or the inside of the body.

However, the sterilizing apparatus 140 generates ultraviolet rays together with ozone to generate the inside of the connecting portion 130 and the main body 110. It can also be sterilized.

In addition, the sterilization apparatus 140 may generate and sterilize a reduced pressure plasma, wherein the reduced pressure plasma is a non-thermal sterilization technique that kills microorganisms at low temperature. That is, the reduced pressure plasma is supplied to air, oxygen, and nitrogen at 350 ml / min under reduced pressure of 1 Torr or less to generate and sterilize the plasma.

Anion generator (not shown) for generating negative ions inside the sterilization device 140 may be further configured, and a sterilization time may be adjusted by installing a timer (not shown) outside the sterilization device 140.

Although the sterilization device 140 is described as being detachably attached to the connection unit 130, the present invention is not limited thereto, and the sterilization device 140 is detachably attached to the suction nozzle 120 to allow the suction nozzle 120 to be detached. When inhaled through the so that can act as a sterilization.

2 and 3, the sterilization device 140, the insertion portion 141 and the insertion portion (141) through which one side and the other side is inserted into the connection pipe 131 of the connecting portion 130, respectively, And a case 143 configured to receive the ozone or ultraviolet generator 142 configured to generate ozone or ultraviolet rays, and to supply power to the ozone or ultraviolet generator 142 configured inside the case 143. Separation unit 145 having a plurality of holes 146 to separate the battery 144 and the ozone generator 142 in the case 143 and to pass ozone or ultraviolet rays generated by the ozone generator 142. It is configured to include.

The blowing fan 150 is configured between the case 143 and the inserting portion 141 to introduce ozone or ultraviolet rays generated from the ozone or ultraviolet generator 142 through the connecting portion 130. Play a role.

Here, the case 143 has an internal space and is a space where ozone or ultraviolet rays generated by the ozone or ultraviolet generator 142 remain, and the ozone or ultraviolet rays generated through the ozone or ultraviolet generator 142 is By operating the blower fan 150, the foreign substance sucked in the state remaining in the case 143 through the hole 146 of the separating part 145 penetrates and sterilizes.

At this time, ozone or ultraviolet rays with the inhaled foreign substances are sterilized to the inside of the dust collecting part 113 while sterilizing the inside of the connecting part 130 while penetrating through the connecting part 130.

Therefore, before cleaning the sterilization apparatus detachable to the vacuum cleaner according to the present invention without cleaning the sterilization apparatus 140 is attached to the blowing fan 150 to operate the connection portion 130 and the main body 110 of the vacuum cleaner If you clean after sterilization, you can clean the room more cleanly.

Figure 4 is a block diagram showing the inside of the main body of the sterilization apparatus detachable to the vacuum cleaner according to the present invention.
