Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a suction body for an electric short cutter, and particularly to a rotating brush for scraping dust from carpets and the like.

(Prior Art) In conventional vacuum cleaners, in order to kill or prevent the reproduction of harmful microorganisms in dust, for example, Japanese Patent Laid-Open No. 59-2
As described in Publication No. 07124, a structure is adopted in which a paper dust collection bag attached to the dust collection chamber inside the vacuum cleaner body is impregnated with chemicals such as insecticides and antibacterial agents. I was trying to exterminate pests and the like in the dust collection department of the cleaning body. However, with the above conventional structure, insects are killed only within the vacuum cleaner body, so pests attached to the inside of the hose, suction mortar, etc. connected to the vacuum cleaner body and located further upstream in the air path are removed. Could not be exterminated. In addition, inside the vacuum cleaner itself, where dust accumulates, the insect repellent concentrates on only a portion of the accumulated dust, so the insect repellent is not effective against all pests and cannot be sufficiently effective. I couldn't. For example, in the vacuum cleaner described in the above-mentioned publication, insect repellent effects can only be obtained in the portion that comes into contact with the dust collection bag.

Although it is not a vacuum cleaner, conventionally, as shown in FIG. A drug dispersion device is known which has a structure in which rIi fabric holes 4 are formed in the opening. In this chemical dispersion device, when the center core 2 rotates in the direction not shown by arrow 8 in FIG. 9(0) as the paper 1 is pulled in the direction shown by arrow A in FIG. 9(c), , the fragrance particles 3 in the core 2 collide and burst, and the fragrance is released from the dispersion hole 4 to the outside. At least one end face portion of is a removable lid 5.

However, in this chemical spraying device, since the core 2 is manually rotated, the amount of aromatic agent ejected is irregular, and sometimes the amount is ejected and sometimes it is not ejected.

(Problems to be Solved by the Invention) As mentioned above, in conventional vacuum cleaners, harmful microorganisms were exterminated within the body of the vacuum cleaner. etc. How many poems 1-
There was a problem that it was not possible to eliminate harmful microorganisms. .

The present invention aims to solve these problems,
The purpose is to eliminate almost all harmful microorganisms that are sucked into the vacuum cleaner body, and also to eliminate harmful microorganisms that settle inside the suction chamber.

In the suction body of the remover, a tank is provided inside the rotating brush in which a chemical such as an insecticide or an antibacterial agent is stored;
A dispersion hole communicating with the outer peripheral surface of the rotary brush from this tank is provided.

(Function) The suction eye of the vacuum cleaner of the present invention is used by connecting the connecting pipe of the case body to, for example, a hose or an extension pipe connected to the dust remover body. During exhalation, a rotating brush located inside the case body and rotated by the drive source scrapes dust from the pipe/υ near the suction port at the bottom of the case body, and this dust is sucked in from the suction port and connected to the Pipe, extension pipe and hose 4 [through Nn
You will be guided to the main body of KR. At this time, the centrifugal force accompanying the rotation of the rotating brush causes pesticides and other chemicals to be centrifugally dispersed from the tank inside the rotating brush onto the outer peripheral surface of the rotating brush through the holes in the fabric. Harmful microorganisms such as dust mites and sterilizers that are sucked in with the dust are killed and injured one after another. At the same time, harmful microorganisms deposited on the rotating brush, inside the case body, inside the hose, etc. are also exterminated.

A fan chamber 20 is formed in the center by the left and right partition walls ia, 19, and this fan chamber 20
A bearing chamber 21 is formed on one side, and a switching operation chamber 22 is formed on the front side. First, the suction I 1114 is opened at the bottom of the brush chamber 17, and the rear center of the brush chamber 17 is communicated with the fan chamber 20 through the opening 23 of the partition wall 16.

Further, an opening 25 through which a connecting pipe 24 projects is formed at the rear of the fan chamber 20 of the case body 11.

This connecting pipe 24 includes a connecting pipe body 26 and a connecting pipe body 26.
It is composed of a semi-cylindrical connecting body 27 formed at the base of the connecting tube 26 and perpendicular to the connecting tube 26, and a connecting tube 28 connected to the tip of the connecting tube 26 so as to be rotatable in the circumferential direction. The partition walls 18 are located on both sides of the connecting body 21.
A shaft portion 30.31 that is rotatably supported by the shaft support 29 formed in 19 is protrudingly provided, and the shaft portion 30.31 of the connecting body 27 can be freely rotated in the vertical direction by coupling both case bodies 12 and 13. The connecting tube body 28 is pivotally supported and protrudes outward from the opening 25 of the case body 11 .

Further, in the turbine fan 32 as a driving source, a rotation @ 33 is projected to one side, and this rotating shaft 33 is rotatably supported in the bearing chamber 21 via a bearing 34.
2 is rotatably disposed in the fan chamber 20 with its rear half covered by the connecting body 27. Further, a gear-shaped pulley 35 is attached to the end of the rotating shaft 33 of the turbine fan 32.

Further, the rotating brush 41 is rotatably disposed in the brush chamber 17 of the case body 11, and a plurality of brush bristles 43 protruding from the suction port 14 are bundled on the outer peripheral surface of the long shaft body 42 of the rotating brush 41. They are planted in a spiral pattern. As shown in FIGS. 1 and 2, the elongated shaft body 42 is hollow, and the inside thereof is filled with a chemical agent 44 such as a liquid insect repellent, insecticide, antibacterial agent, or bactericide. It has become tank 45. Further, as shown in FIG. 3(c), this tank 45 opens to one end surface of the elongated sleeve body 42, and this opening serves as an inlet 46. Furthermore, as shown in FIG. 2, a support wall 48 is formed in the central portion of the elongated shaft 42 in the longitudinal direction, for example, to support a support shaft 47 that is fixed through the central shaft portion of the shaft 42. However, a communication hole 49 is formed in this support wall 48, and both sides of the tank 45 sandwiching the support wall 48 communicate with each other through the communication hole 49. The brush bristles 43, which are made of polyamide and have elasticity, have a hollow cylindrical shape as shown in FIG.
The interior of the brush bristles 43 forms a dispersion hole 50 that communicates from the tank 45 to the outside of the rotating brush 41.

Further, as shown in FIG.
A plurality of semicircular arc-shaped engagement protrusions 51 are protruded from the circumferential surface of the side end at intervals, for example, at four locations.

On the other hand, a gear-shaped pulley 52 to which the end of the elongated shaft 42 on the inlet 46 side is removably fitted has a fitting hole 53 formed on its inner surface into which the shaft 42 of the rotating brush 41 is fitted. An engagement recess 54 to which the engagement protrusion 51 is coupled in the rotational direction is formed on the inner periphery of the engagement hole 53 so as to correspond to the engagement protrusion 51 . Also, in the center of this pulley 52, there is a
A sleeve support hole 55 is formed through the sleeve. Furthermore, the pulley 5
A backing 56 that liquid-tightly closes the injection port 46 is fitted into the bottom of the second fitting hole 53. This backing 56 is formed with a fitting protrusion 57 that is removably fitted into the end of the tank 45 surrounding the support shaft 47, and a shaft support hole 58 is formed through the center of the protrusion 57. ing.

And the backing 56 and the shaft support hole 5 of the pulley 52

are rotatably fitted.

Further, as shown in FIGS. 4 and 5, the rotating brush 4
A disk-shaped receiving plate 60 is fixed to the end surface of the elongated shaft body 42 on the side opposite to the pulley 52, and a bearing body 61 is attached to the end of the support @47 that passes through this receiving plate 60. are rotatably fitted.

Both bearing bodies 59 and 61 are detachably held by bearing holding portions 62 formed on both sides of the brush v17 of the case body 11. This bearing holding part 62 has a projecting wall 64.65 that engages the front edge of a substantially rectangular engaging part 63 formed on the outer periphery of the bearing body 59.61, and is inclined from above to below to the rear side in the front and rear directions. It protrudes in parallel.

Further, the belt 71 is suspended around the pulleys 35 and 52, and an uneven portion is formed on the inner surface of the belt 71 to mesh with the outer peripheral gear-shaped surfaces of the pulleys 35 and 52. is the rotating brush 41
transmitted to.

The switching operation chamber 22 of the case body 11 is provided with a sliding plate 7 for adjusting the opening area of the opening 23 of the partition wall 16 communicating with the fan chamber 20 formed at the rear center of the brush chamber 11.
Two switching actuating bodies 73 are provided, and this switching actuating body 7
When the opening area of the opening 23 is narrowed by the operation in step 3, the suction port 1
The suction wind from 4 is strongly blown to the turbine fan 32,
Turbine fan 32 is rotated.

The upper opening 15 of the rotating brush chamber 17 of the case body 11 is opened and closed by a detachable upper cover 74. This upper cover 74 has a movable locking pawl 76 that is slidably engaged with an engaging portion 75 formed at both ends of the front edge of the upper case body 12, and this movable locking pawl 76 protrudes from the upper surface of the upper cover 74. When the knob 77 is operated, the engagement portion 75 is engaged and disengaged.

Note that a window hole 79 is formed in the upper surface of the upper case body 12 from which a knob 78 of an operating body 73 for opening and closing the opening 23 of the fan chamber 20 projects.

Next, the operation of this embodiment will be explained.

When the connecting pipe body 28 of the connecting pipe 24 of the suction port case body 11 is connected to the electric repatriation machine body via a hose, an extension pipe, etc., and the evening blower in the electric repatriation specimen body is driven, the case body Dust etc. and air are sucked in from the suction port 14 of 11. The air together with the dust sucked in from the suction port 14 flows into the fan chamber 20 from the opening 23 of the rotating brush chamber 17. At this time, if the opening 23 is narrowed by the sliding plate 72, the air flows to the turbine fan 32. While rotating the turbine fan 32, it is guided by the connecting body 27, and is sucked into the electric remover body through the connecting pipe body 2B, extension pipe, hose, etc.

The rotation of the turbine fan 32 rotates the rotating shaft 33, driving the belt 71 suspended around the pulley 35, and the belt 71 rotates the pulley 52 connected to the shaft body 42 of the rotating brush 41, causing the engagement of the pulley 52. When the engagement protrusion 51 of the shaft body 42 of the rotating brush 41 is engaged with the recess 54, the rotating brush 4
1 is rotated, and the bristles 43 of this rotating brush 41 scrape up dust on the surface to be cleaned, such as dirt, etc., and suck it in through the suction port 14.

At this time, due to the centrifugal force accompanying the rotation of the rotating brush 41, chemicals 44 such as insecticides are sprayed outward from the tank 45 in the shaft body 42 of the rotating brush 41 through the spray holes 50 in the brush bristles 43. . In this way, the chemicals that are centrifugally sprayed over the entire area of the rotating brush chamber 11 kill dust mites, sterilizers, and other harmful microorganisms that are sucked in one after another along with the dust, and are exterminated in a continuous manner. go. Therefore, almost all harmful microorganisms that are sucked into the vacuum cleaner body are exterminated. Incidentally, dust does not adhere to the inner surface of the straight extension pipe that is in the air path from the suction port 14 to the returning aircraft body, but dust does not adhere to the inner surface of the case body 11 and the connecting pipe 24 or the bows, which have bent portions. It is easy to collect dust.

(2) However, since harmful microorganisms are exterminated near the suction port 14, which is the most upstream part of the air passage, the harmful microorganisms that have adhered to the case body 11 or inside the hose together with, for example, dust have already been exterminated. Hygienic. Of course, since the chemical agent 44 is sprayed from the rotating brush 41, harmful microorganisms that adhere to the rotating brush 41, which is particularly susceptible to getting entangled with dust, can be effectively exterminated.

Also, the brush bristles 43 are used to scratch the cleaning surface, for example, carpet hair.
Since the chemical agent 44 is ejected from the air, the chemical agent 44 is effectively blown into the carpet, thereby ensuring that the carpet is also disinfected.

Since the rotating brush 41 is rotationally driven by the turbine fan 32, the rotating brush 41 continues to rotate evenly and reliably during cleaning, and therefore the chemical agent 44 is reliably spread.

Furthermore, since the spraying is performed by centrifugal force, there is no need for a special rl1m device, and the structure is simple.

Also, when the drug 44 in the tank 45 of the rotating brush 41 runs out, the tank 45 is refilled with the drug 44.

To do this, first remove the upper cover 74 from the case body 11 to expose the rotating brush 41 in the rotating brush chamber 17, as shown in FIG. After removing it from the section 62, pulley 52
The side bearing body 59 is removed from the bearing holding part 62, the pulley 52 is removed from the belt 71, and the rotating brush 41 is removed. Next, as shown in FIG. 3(2), pulley 52 and backing 5 are removed from one sleeve body 42 of one rotational brush 41 taken out.
Remove the drug 44 by pulling it out, and pour the drug 44 into the tank 45 between the outer wall of the shaft body 42 and the support @ 41 through the opened injection port 46.
inject.

As shown in FIG. 1(2), the backing 56 is pushed into the end of the shaft 42 as before, and the engagement protrusion 51 of the shaft 42 and the engagement recess 54 of the pulley 52 are At the same time, the end of the shaft body 42 is fitted into the fitting hole 53 of this pulley 52. In this state, the shaft body 42 is coupled to the pulley 52 in the rotational direction, and the injection port 46 is fluid-tightly closed by the backing 56 interposed between the shaft body 42 and the pulley 52. While roughly hanging the belt 71 around the pulley 52, the bearing body 59 on the pulley 52 side is engaged with the bearing holding part 62, and then the bearing body 61 on the opposite side is engaged with the bearing holding part 62, and the rotating brush 41 is attached to the case. It is attached to the main body 11 and the upper cover 74 is attached to cover the opening 15 of the case main body 11.

Since the large injection port 46 is opened and closed by the pulley 52 as a lid, the user can easily inject the medicine 44 into the tank 45.

In addition, the pulley 52 is removably attached to the injection port 46 for the drug 44.
The structure is simple because it also serves as a lid for a car.

Also, when removing dust entangled with the bristles 43 of the rotating brush 41, the rotating brush 41
If you remove it, you can do the work easily. Of course, it is also possible to clean the rotating brush 41 during the injection work of the medicine 44. By the way, to remove dust such as lint, use the rotating brush 4.
1 in the rotating direction, the shaft 4 of the rotating brush 41
Remove the pulley 52 with a larger diameter than this shaft body 42 from 2,
Remove entangled dust in the axial direction of the rotating brush 41 and inlet 4.
You can easily remove dust by squeezing it out in the direction of 6.

In the above embodiment, the turbine fan 32 is used as the drive source for rotationally driving the rotary brush 41, but the drive source may be an electric motor.

Furthermore, although the spray holes 50 through which the medicine 44 is ejected are formed in the brush bristles 43, the spray holes may be formed on the peripheral surface of the shaft body 42 of the rotating brush 41, for example, along the arrangement of the brush bristles 43. However, as in the above embodiment, the rotating brush 4
If the dispersion holes 50 are formed in the brush bristles 43 that protrude in the outer radial direction from the shaft body 42 of No. 1, the rotation radius of the tip of the brush bristles 43 is larger than the rotation radius of the outer circumferential surface of the shaft body 42, so that the drug can be sprayed. The spread of the chemical agent 44 is increased, and the chemical agent 44 is more likely to hit the inner surface of the rotating brush chamber 11, so that harmful microorganisms can be exterminated over a wider area.

Further, dispersion holes may be provided in both the brush bristles 43 and the peripheral surface of the shaft body 42, so that the ejection surface of the medicine 44 may be formed in two layers.

Further, instead of having a plurality of dispersion holes, the number of dispersion holes may be one elongated groove.

In any case, if the dispersion hole is provided near the brush bristles 43,
This is effective in disinfecting the brush bristles 43 to which dust tends to adhere.

Further, in the above embodiment, the injection port 46 for the drug 44 was provided on the end surface of the shaft body 42 of the rotating brush 41, but the injection port may be provided on the peripheral surface of the shaft body 42. In this way, the medicine 44 can be injected without removing the rotating brush 41 from the case body 11. However, if the inlet 46 is provided on the end face of the shaft body 42 as in the above embodiment, the pulley 5 is attached to the lid for the inlet 46.
It is also possible to use both.

Further, the medicine 44 may be injected through the dispensing hole 50 using a special machine, but this makes it difficult for the user to carry out the injection work.

Further, the number of tanks 45 within the rotating brush 41 may be two or more. For example, in the above embodiment, if the support wall 48 at the center of the shaft body 42 of the rotating brush 41 does not have a communication hole 49, two tanks 45 are arranged in the axial direction of the rotating brush 41 and separated from each other. will be formed.

Note that when this structure is adopted, the pulley 52 of the shaft body 42
It is preferable that an injection port is also formed on the opposite end surface, and the receiving plate 60 also serves as a lid for closing this injection port. In this way, if the tanks 45 are made into two, for example, two types of chemicals 44 can be sprayed at the same time by injecting different chemicals into each tank 45, such as a combination of an insecticide and an antibacterial agent or an insecticide and an aromatic agent. be able to. Furthermore, the two types of chemicals 44 are dispersed uniformly in a retrograde manner.

Furthermore, the plurality of tanks 45 may be arranged in the rotational direction of the rotating brush 41 instead of in the axial direction. In this way, different chemicals 44 can be injected into each tank 45 from the inlet 46 on the same end face of the shaft 42 of the rotating brush 41, for example. At the same time, the plurality of medicines 44 are distributed uniformly in terms of position.

Next, still other embodiments of the present invention will be described in FIGS. 6 to 8.
The diagram will be explained.

In this embodiment, the pressure is set at 1 so that the agent 44 is also sprayed from the turbine fan 32.

The turbine fan 32 has a cylindrical sleeve part 81 in the center to which eleven rotating shafts 33 are fixed, and a cylindrical wall 82 located concentrically on the outer circumferential side of the sleeve part 81 on the right side. The sleeve portion 81 and the cylindrical wall 82 are integrally connected by a number of connecting walls 83. Furthermore, a plurality of blades 84 are integrally formed radially on the outer peripheral surface of the cylindrical wall 82 to receive airflow. Further, these cylindrical walls 82 and blades 8
Disk-shaped side walls 85 and 86 are provided on both end surfaces of the 4, respectively.

A tank 87 is filled with the drug 44 between the sleeve portion 81 and the cylindrical wall 82.

Furthermore, the tank 87 is connected to the outside at a position between the nodes 84 that go down the cylindrical wall 82 . ! J number of dispersion holes 88 are formed. Sea urchin tank 8
7 is opened to a side wall 86 opposite to the side wall 85 from which the rotating shaft 33 projects, and this opening serves as an inlet 89. The injection port 89 opens at the bottom of a recess 90 formed on the outer surface of the side wall 86. Reference numeral 91 denotes a backing that is removably fitted into the recess 90 and closes the injection port 89 liquid-tightly.
is a fitting protrusion 9 that is inserted into the end of the sleeve portion 81 once.
2 in the center.

The turbine fan 32 and a bearing 34 that pivotally supports its rotating shaft 33 are removably attached to the case body 11.

During cleaning, the centrifugal force caused by the rotation of the turbine fan 32 causes the chemical 4 to be sprayed from inside the tank 87 through the spray hole 88.
4 is ejected to the outside.

Furthermore, when injecting the drug 44 into the tank 87 inside the turbine fan 32, the turbine fan 32 is
After removing the backing 91 from the turbine fan 32, the medicine 44 is injected into the tank 8 through the opened injection port 89. Thereafter, the backing 91 is attached to the turbine fan 32 again, and the inlet 89 is closed with a single stroke, and the turbine fan 32 is attached to the case body 11 as before.

According to the above configuration, in addition to the spraying of the chemicals 44 by the rotary brush 411 and the like, the chemicals 44 are also sprayed from the turbine fan 32, so that the effect of exterminating harmful microorganisms becomes even stronger.

In addition, in order to select between rotation and non-rotation of the rotary brush when the rotary brush is stationary, a communication chamber that communicates with the rotary brush chamber connection 11 and a turbine fan chamber are separated and formed into sections, and these communication chambers and the turbine fan chamber are separated. In the suction itself of the electric welding machine, which has a structure in which the water is selectively communicated with the rotating brush chamber, 1.
1. By providing the tank 87 in addition to the turbine fan as described in Section 2, the following effects can also be obtained. In other words, when the rotating brush chamber and the turbine fan chamber are cut off to exterminate bacteria without rotating the rotating brush, the turbine fan 32 does not rotate, but at this time, the negative pressure in the turbine fan chamber is increased by the suction force of the vacuum cleaner itself. As the pressure increases, the chemical 44 is sprayed from the tank 87 of the turbine hood 32 through the spray hole 88 due to this negative pressure. can be done.

〔Effect of the invention〕

According to the present invention, a tank in which a drug is stored is provided inside the rotating brush, and a dispersion hole is provided that communicates with the outer peripheral surface of the rotating brush from the tank, so that the drug is dispersed by the centrifugal force caused by the rotation of the rotating brush. As the harmful microorganisms that are scattered, scraped out by the rotating brush, and sucked in are exterminated one after another, the harmful microorganisms 4' that are sucked into the vacuum cleaner body can be thoroughly exterminated. It is also possible to exterminate harmful microorganisms that may be present in the body during suction, including the rotating brush. Furthermore, since the rotating brush is driven to rotate by the drive section, the chemical can be reliably sprayed. Furthermore, since the spray is sprayed using centrifugal force, there is no need for special spray equipment.
