Description

Vacuum cleaner inhalation nozzle for dust and tick cleaning}

The present invention relates to a vacuum cleaner suction nozzle for cleaning fine dust and mites, and more particularly, to completely remove the fine dust remaining in fabrics such as bedding and sofas by using the pressure difference of air sucked into the vacuum cleaner body. A vacuum cleaner suction nozzle for cleaning dust and mites.

Vacuum cleaners, which are generally used, are vacuum cleaners for sucking foreign substances such as dust by using suction force of the low pressure part, and are essential household appliances of the home.

However, various foreign substances sucked into the vacuum cleaner pass through the paper filter in the cleaner, and there is a problem that most of the fine dust of about 0.35 micrometers is discharged again through the double cleaner outlet.

Accordingly, in the related art Utility Model Publication No. 1998-0015512 (name: installation structure of the vacuum cleaner filter) is proposed to prevent fine dust re-emitted in the room, the first filter and first In addition to the first composite filter including the one fine filter is provided, the rear of the motor has shown the configuration of the second composite filter consisting of the second filter and the second fine filter integrally.

Due to this double filter structure, not only the odor generated from the fine dust and foreign matter sucked during vacuum cleaning is removed by the first composite filter, but also the fine dust and odor generated from the motor that are not removed from the first composite filter are removed. Although it is removed by the second composite filter, it is difficult to see that the actual fine dust emission is completely controlled, and in a home equipped with a vacuum cleaner, there is no great effectiveness due to the burden of replacing the entire vacuum cleaner. In addition, when used for general floor cleaning, relatively large particles of foreign matter are excessively trapped in the first composite filter, preventing the air from being transferred, and the second composite filter reduces the air discharge rate to the outside. The suction force is greatly reduced, and there is an inconvenience in that the filter needs to be replaced and cleaned from time to time during cleaning.

On the other hand, the suction nozzle for normal floor cleaning is provided with a structure in which the entrance is extended while the wheel is provided at the bottom, and is not suitable for cleaning a lot of fine dust fabrics such as bedding, cloth sofa, carpet, and the like.

That is, unlike the general suction nozzle, the fine dust suction nozzle has a separate control hole for reducing the suction power of the main body to prevent the fabric or the like from being easily sucked onto the suction nozzle, or the dust and mite remaining in the fabric. In order to clean it, a suction nozzle exclusively for cleaning fine dust with an additional impact rod should be used.

In this way, the suction nozzle is not distributed on the market as the structure is improved in various ways to suit the intended use, but even if the suction performance of foreign substances is improved, this is a high discharge as the forced air discharged through the filter by the amount of air sucked by the vacuum force of the main body As the air gap of the filter expands due to the pressure, the invisible fine dust of 0.3 ~ 0.5㎛ cannot be filtered out, and most of it is re-extracted in the air and contaminates the indoor air, thus obtaining the stigma of the fine dust generator. Adverse effects (eg, asthma, allergic rhinitis, respiratory disease).

The present invention has been made to solve the above problems, in cleaning the textiles such as bedding, cloth sofa, carpet, etc., by simply replacing the existing vacuum cleaner suction nozzles to clean fine foreign matters such as carcasses, dust, etc. An object of the present invention is to provide a vacuum cleaner suction nozzle for collecting dust and mites to prevent indoor air pollution by collecting.

In addition, the present invention by using the air pressure difference of the air introduced into the cleaner, the fine dust is first collected through a filter provided on the suction nozzle, the user can easily collect and process the collected foreign matter without opening the body and In addition, the object of the present invention is to reduce the air discharge pressure applied to the main body filter and to completely remove fine dust of 0.35 micrometer or less.

In order to achieve this object, a feature of the present invention is that a fastening tube 12 detachably assembled on a handle bar 3 connected to a vacuum cleaner body 1 via a hose 2 is installed at one end, and a lever is provided.

It characterized in that it comprises a; collection case 40 through which the second suction port 44 penetrates.

At this time, the filter 30 is characterized in that it is provided with a pleated drum HEPA filter bent in a zigzag.

In addition, the UV lamp 50 is installed on the bottom of the lower case 20, the UV lamp 50 is characterized in that it is provided to be operated by the battery 52 or the vacuum cleaner main body (1) power.

According to the above configuration and operation, the present invention is the first collected through the filter provided on the suction nozzle, the user can easily collect the foreign matter collected by the user without opening the body, and particularly provided on the suction nozzle As the amount of intake air flowing into the main body is partially reduced by the filtered filter, the air discharge pressure applied to the main body filter is reduced to prevent fine dust from leaking out due to forced discharge of air, thereby keeping the indoor air clean even after cleaning. It is effective.

In addition, in cleaning textiles such as bedding, cloth sofas, carpets, and the like, by simply replacing the suction nozzle of the vacuum cleaner being used, fine dust can be cleaned, thereby reducing the household burden on the user.

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

The present invention relates to a vacuum dust suction suction nozzle for cleaning fine dust and mite, wherein the vacuum dust suction suction nozzle for cleaning dust and mites is easily applied to a vacuum cleaner used in the past, and can be easily applied to fabrics such as bedding, cloth wave, carpet, etc. In the cleaning, the upper case 10, the lower case 20, the filter 30, the collection case 40 is composed of a main configuration to cleanly collect fine foreign matter.

In the upper case 10 according to the present invention, a fastening tube 12 detachably assembled on a handle bar 3 connected to the vacuum cleaner body 1 through a hose 2 is installed at one end thereof, and a lever 14a is provided. There is provided an air inlet 14, the opening and closing amount is adjusted according to the air flow rate. The upper case 10 is integrally assembled with the lower case 20 to be described later to form an external shape of the suction nozzle, and the fastening tube 12 is installed at one end so as to communicate with the inside of the upper and lower cases 10 and 20. . The fastening pipe 12 has a fastening part (not shown), such as a protrusion or a screw part, is formed at one end in consideration of the fastening structure of the suction nozzle for each manufacturer in the market, and the other end is a hinge 10a formed on the outer circumferential surface thereof. It is installed to be pivotable on the upper case (10).

In addition, although the air inlet 14 has a configuration formed on the upper case 10 in FIG. 1, the configuration is not limited thereto but may be provided on the side or the front surface which is easy for the user to operate, and the lever 14a The opening and closing amount is adjusted by the) to supply external air to the upper and lower cases 10 and 20.

This is because when the cleaning of the fabrics such as bedding, cloth sofa, carpet, etc., the fabric flows into the first intake port 24 of the lower case 20 to be described later, so that additional air is supplied through the air inlet 14. As a result, the air suction pressure flowing into the first intake port 24 is partially reduced, so that the cloth can be cleaned more conveniently.

In addition, the lower case 20 according to the present invention is coupled to the lower upper case 10, the wheel 22 and the first suction port 24 is provided on the bottom. The wheel 22 is provided to protrude on the lower case 20, the wheel 22 provided in the front is pivotally installed to facilitate the transfer in the direction of the suction nozzle, the wheel 22 is provided at the rear ) Serves to support the suction nozzle during transfer in the front and rear directions. In addition, the wheel 22 supports the bottom surface of the lower case 20 so as not to be adsorbed to the surface of the fabric and is kept spaced apart, thereby preventing the first suction port from being blocked.

At this time, the first suction opening 24 is cut in the form of a long hole in the bottom surface of the lower case 20 corresponding to the cleaning surface to suck air and foreign matter by the suction force of the vacuum cleaner main body 1, and the first suction opening 24 is opened. The air including the foreign matter introduced through is transferred onto the vacuum cleaner body 1 through the second suction port 44 and the filter 30 of the collection case 40 which will be described later.

In addition, the filter 30 according to the present invention is installed in the upper and lower cases 10, 20, foreign matter on the air introduced through the first suction port 24 in a position communicating with the fastening pipe 12. It is provided to filter the. The filter 30 uses a pleated drum HEPA filter zigzag bent in order to secure an extended filter area, and primarily filters foreign substances in the air introduced through the first and second inlets 24 and 44. Not only plays a role, but also reduces the flow of air to induce the clean air that is primarily filtered by using the suction force generated in the vacuum cleaner body (1).

That is, the filter 30 is positioned on the flow path between the fastening tube 12 and the first suction port 24 to reduce 20 to 30% of the suction force generated in the vacuum cleaner main body 1 to reduce 70 to 80% of air. As the induction of the inflow of the air discharged through the main body filter F is reduced, the discharge pressure applied to the main body filter F is also reduced. Therefore, as air as much as the suction force generated on the vacuum cleaner main body 1 is forced out through the main body filter when the air is sucked in, the pores are expanded due to the high pressure applied to the main body filter, thereby preventing fine foreign matters from being collected. Problems such as being discharged to the outside are solved.

In addition, the collection case 40 according to the present invention is provided in the upper and lower cases 10, 20 to accommodate the filter 30 is provided with a lower fixing device 42 which is open to the bottom of the lower case 20 The second suction opening 44 penetrates to one side corresponding to the first suction opening 24. The collection case 40 forms a compartment for accommodating a filter in the upper and lower cases 10 and 20, and external air introduced onto the first suction opening 24 through the second suction opening 44 on one side thereof. Inhale.

In this case, as the second intake 44 is located lower than the filter 30 and higher than the bottom surface of the lower case 20, as shown in FIG. 3, the second air inlet 44 passes through the second intake 44. The flow is converted to the upper part and flows into the filter 30, and the foreign matter in the relatively large particulate state contained in the air is dropped by the centrifugal force and collected at the bottom of the collection case 40. After the cleaning is completed, the lower fixing device 42 is opened on the bottom of the collection case 40 to easily collect the foreign matter.

In addition, the UV lamp 50 is installed on the bottom surface of the lower case 20, the UV lamp 50 is provided to be operated by the battery 52 or the vacuum cleaner main body (1) power. UV lamp 50 is a lamp that emits ultraviolet light for sterilization action, is installed to be accommodated on the bottom of the lower case 20, wherein the UV lamp 50 is accommodated in the lower portion to increase the radiation amount of the UV lamp 50 It is preferable to provide a reflection shade in the groove portion of the case 20. Although not shown in detail through the drawings, the UV lamp 50 may be formed by separately forming a battery case on the bottom of the lower case 20 to supply power to the battery 52 or to use the power of the vacuum cleaner main body 1. A separate power line is provided.

Thus, while cleaning the fabrics, such as bedding, cloth sofa, carpet, etc., the sterilization action to remove microorganisms as well as various pathogens and mites inhabiting the fabrics is easily performed.

On the other hand, although not shown through the drawings, it is preferable that the UV lamp 50 is provided with a switch to turn on / off the power supply as needed.

Looking at the operating state of the vacuum dust suction nozzle for cleaning the dust and mites of the present invention configured as described above, the first installation of the suction nozzle through the coupling tube 12 on the handle bar (3) of the existing vacuum cleaner Is done.

Subsequently, when the UV lamp 50 and the vacuum cleaner main body are turned on, and then the surface of fabrics such as bedding, cloth sofa, carpet, and the like are rubbed and transferred, the external air containing foreign matter is passed through the first suction port 24 to the second suction hole 44. ) Is introduced into the filter 30, where the external air is passed through the second inlet 44, the transfer direction is switched, the foreign matter in the relatively large particulate state is dropped by the centrifugal force to the bottom of the collection case (40) The foreign matter in the collected and relatively small particulate state is caught primarily on the filter 30.

In addition, as the intake air is first filtered by the filter 30, the flow rate is lowered, so that a smaller amount of air is introduced than the suction force of the vacuum cleaner body 1. Since it is reduced together, the discharge of fine foreign substances due to the expansion of the air gap of the main body filter (F) is blocked, there is an advantage that the pollution of the indoor air is prevented.

Figure 4 is a graph showing the pressure difference of the air sucked when using the vacuum dust suction nozzle for cleaning fine dust and ticks according to the present invention.

The principle of the vacuum cleaner is to use the absorption force of the low pressure portion, the less air molecules, the lower the pressure, the fine dust is sucked into the low pressure portion. Atmospheric pressure is typically 760 Torr, and the pressure inside the cleaner is reduced to about 600 Torr. 4 is a view illustrating a mode in which the pressure of the air introduced into the suction device is gradually lowered. When external air and dust are sucked from the suction unit, the conditions and functions for which pressure is desired based on the pressure difference between the inlet and the outlet are shown. Hydrodynamic adjustment to suit.
