The following description is provided to help the understanding and practice of the present invention, but is not intended to limit the present invention thereto. Those skilled in the art will understand that various modifications and variations can be made within the spirit of the invention as set forth in the following claims.

1 is a structural diagram of a cleaner 10 of the present invention. Hereinafter, components and schematic operation of the cleaner 10 of the present invention will be described with reference to FIG. 1 .

Prior to the description, the arrow in the cleaner 10 of the present invention shown in FIG. 1 indicates the direction of air flow.

As shown in FIG. 1, the cleaner 10 of the present invention has a suction/blower unit 100 capable of sucking in foreign substances or discharging wind to the outside, a power source and a rotating unit to the inside, and components such as an impeller. The main body 200, which is a body including these, and the suction/blowing unit 100 can store foreign substances sucked in, and also open standardized garbage bags, sacks, sacks, etc. inside for storage of foreign substances. It includes a collection unit 300 that can be hung or inserted.

When all the components are described in detail, the suction/blower unit 100 provides a pressure for sucking an external foreign substance or serves to push the foreign substance by blowing the wind, and for this purpose, the suction pressure is provided Separate the pipe and the pipe for blowing, preferably, the suction pipe 110 and the blower pipe 120 are double pipes, and the suction pipe 110 is inserted into the blower pipe 120 in a spaced state, so that the blower pipe ( The wind discharged by the 120 is configured to blow out into the gap between the blower pipe 120 and the suction pipe 110 .

The reason for moving the suction pipe 110 inside the blower pipe 120 as described above is that in the case of the suction pipe 110, various types of foreign substances must be able to be sucked in. The reason for making a double pipe having an inner diameter and an outer diameter, rather than a separate tube, is to suck the wind blown by the blower pipe 120 back into the suction pipe 110, so that the air in the cleaner 10 of the present invention is in order to circulate.

In addition, between the blower pipe 120 and the suction pipe 110, one or more frames 111 for fixing the space apart between the two are included and installed between the suction pipe 110 and the blower pipe 120 .

And the main body 200 includes a suction path 210 and a blowing path 220 . An impeller 212 which is a fan rotating by the operation of the rotating unit 211 and the rotating unit 211 is installed in the suction path 210 , and the main body 200 is a power source for providing energy to the rotating unit 211 . (213) is installed.

Here, the rotating part 211 may be achieved using, for example, a motor or a small engine, and the power source 213 may be, for example, an electric battery or a fuel supply tank and a supply device for an engine.

Therefore, a negative pressure sucked in the suction path 210 is generated by the rotational operation of the impeller 212, and the suction pipe 110 connected by the negative pressure generated in the suction path 210 can suck in foreign substances. Also, foreign substances sucked in through the suction pipe 110 are transferred to the collection unit 300 through the suction path 210 .

At this time, as shown in FIG. 1, the impeller 212 is positioned on the suction path 210 so that foreign substances moving through the suction path 210 collide with the rotating impeller 212 blade to be crushed. In this case, since the blade of the impeller 212 can sufficiently crush foreign substances and has a hardness that is not damaged by impact, the blade of the impeller 212 is preferably made of a metal material having a certain hardness or higher. do.

In addition, on the suction path 210, in addition to the suction pipe 110, one or more second suction pipes 130 capable of sucking external foreign substances may be extended and installed.

A preferred installation form of the second suction pipe 130 is, as shown in FIG. 1 , to provide suction pressure downward in a form close to or perpendicular to the bottom part while being attached to the main body 200. It is preferable to manufacture in a shape so that foreign substances under the main body 200 can be naturally sucked while moving the main body 200 .

In addition, when the second suction pipe 130 is installed in a desirable shape as described above, a length adjusting part 131 is installed so that the length can be adjusted according to the height of the ground, so that the total length of the second suction pipe 130 is to be able to adjust

At this time, the means by which the length adjustment part 131 can adjust the length on the second suction pipe 130 uses a conventional sliding locking part or a screw thread type.

In addition, one or more wheels 230 may be installed at the lower end of the main body 200 for convenient transport. Preferably, in order to be stably positioned on the ground, three or more wheels 230 are installed, and at least one of them is installed to be rotatable.

In addition, the collecting unit 300 includes a receiving unit 310 inclined in a rhombus shape connected to the suction path 210 and the air blowing path 220, and a collecting container 320 for storing incoming foreign substances. ) is included.

Here, the collection container 320 may be mounted or formed by including a separate hanging means that can be mounted or mounted by unfolding a general garbage bag or a sack bag.

By configuring as described above, foreign substances such as fallen leaves introduced through the suction path 210 are stored away from the container 320, and the air is discharged to the outside through the ventilation path 220 again to the container 320. It is to allow the wind to be discharged through the blower path 220 and the blower pipe 120 while maintaining a constant pressure.

In addition, an opening/closing unit 230 may be further installed in the middle on the suction path 210 and the blowing path 220 .

2 is an enlarged structural diagram of the opening/closing unit 230 . Hereinafter, an operation of the opening/closing unit 230 will be described with reference to FIG. 2 .

The opening/closing unit 230 is installed in a portion where the suction path 210 and the blowing path 220 abut, and is installed in the abutting portion and rotates to open and close the suction path 210 and the blowing path 220 It includes a switch 231 that can open and close, and an opening 232 that can accommodate the switch 231 and is formed in a portion where the suction path 210 and the air blowing path 220 are in contact with each other.

The switch 231 is rotated on the opening 232 to open and close the suction path 210 and the blowing path 220. In normal times, as shown in FIG. It is positioned so as to be parallel to the path direction of the 210 and the blowing path 220 and does not block both paths 210 and 220 .

Then, when the switch 231 rotates according to the user's need and is positioned in a direction perpendicular to both paths 210 and 220 as shown in FIG. 2(b), both paths 210 and 220 and the collection unit 300 The pathways between the liver may be blocked. Due to the path closure due to the operation of the switch 231 as described above, the air sucked through the suction path 210 is blocked by the switch 231, and the air blow path 220 through the open opening 232 again. is transported to and discharged through the blower pipe 120 . In conclusion, the operation of the opening and closing unit 230 can be used when the vacuum cleaner of the present invention wants to use only the blowing function without using the suction function.

In addition, the opening/closing unit 230 further includes an automatic or manual rotation operation device for operating the opening/closing unit 231 . The rotary operation device of the switch 231 may include a series of devices that are configured fully automatically using a rotating unit that obtains power from the power source 213 or that a user directly rotates the rotation device. The configuration and operation of the operating device may utilize conventional techniques, and thus a detailed description thereof will be omitted.

3 and 4 are enlarged structural diagrams of the ends of the suction pipe 110 and the blower pipe 120 of the present invention. Hereinafter, an end-side operation of the suction pipe 110 and the blower pipe 120 of the present invention will be described with reference to FIGS. 3 and 4 .

As described above, the vacuum cleaner of the present invention has a double pipe structure in which the suction pipe 110 is inserted while being spaced apart from the inside of the blower pipe 120 . In this way, one of the goals of the present invention is to solve both the suction of foreign substances through the suction pipe 110 and the blowing through the blower pipe 120 with a single pipe.

However, as in the description through the above-described components, the suction operation through the suction pipe 110 and the blowing operation through the blower pipe 120 operate simultaneously without operating separately. Since the opening/closing unit 230 blocks only the path to the collection unit 300, there is no change in that both the pipes 110 and 120 operate. This is natural in terms of configuration because the exhaust path of the air sucked through the impeller 212 is the blower pipe 120 .

However, since the user who wants to use the vacuum cleaner of the present invention will select and use either the suction function or the blowing function of foreign substances using the vacuum cleaner of the present invention, the user can use only the suction function or the blowing function using the present invention. should be able to make Because when you want to use the suction function, the operation of the blower pipe 120 through which the wind is discharged in the opposite direction only interferes, and likewise, when only the blowing function is used, the function of the suction pipe 110 for sucking the wind in a vast direction is hindered. act as an element. Therefore, in the present invention, the suction pipe 110 or the blower pipe 120 is to be used by dividing the two by a method of protruding any one of the pipe to be used.

To this end, as shown in FIG. 3 , the length adjusting unit 130 is installed in the suction pipe 110 or the blower pipe 120 . Specifically, the length adjustment part 130 includes a length adjustment groove 131 and an adjustment pin 132 , wherein the length adjustment groove 131 is provided in either the suction pipe 110 or the air blower tube 120 . formed, and the adjusting pin 132 is formed or installed in the other tube, the adjusting pin 132 slides along the length adjusting groove 131 so that the adjusting pin 132 adjusts the length By ascending and descending along the groove 131 , the distance between the suction pipe 110 and the blower pipe 120 may be widened.

By doing as described above, it is possible to achieve the above object of using only one of the suction function and the blowing function. If the suction pipe 110 protrudes in front of the blower pipe 120, the blowing function of the blower pipe 120 to discharge wind is the same as that occurring on the side of the pipe, so that the suction pipe 110 does not interfere with the foreign substance suction function. do. Similarly, if the blower pipe 120 protrudes in front of the suction pipe 110 , the end of the pipe only has a blowing function for discharging wind, and the suction of wind occurs only inside the pipe, so the blowing function of the blower pipe 120 is disturbed. won't do it

Here, the length adjustment groove 131 may be formed in a straight shape in which one or more bent fixing grooves are formed as shown in FIG. 3, or may be formed in a screw groove shape as shown in FIG. 120), it is also possible to naturally elevate the tube by the rotation.

5 is an enlarged structural view of the top surface of part A of FIG. 1 .

As shown in FIG. 5 , one or more openable and openable suction grooves 112 may be formed on the surface of a portion exposed to the outside of the suction groove 110 in the cleaner of the present invention.

The suction groove 112 is to allow wind to be introduced through the suction groove 112 when the user opens it, which opens the suction groove 112 when only a blowing operation is performed through the blower pipe 120 to open the suction groove 112. By introducing wind through the suction groove 112 , the operation of the suction pipe 110 that relatively interferes with the blowing operation of the blower pipe 120 is minimized. Alternatively, by further including components such as a separate lid, the suction pipe 110 is blocked and only the suction groove 112 is opened to use only the blowing operation.

6 is a side structural diagram of the suction pipe crusher 112 that may be installed in one or more suction pipe 110, and FIG. 7 is a front structural view of the suction pipe crusher 112. As shown in FIG. Hereinafter, the configuration and operation of the suction pipe crusher 112 will be described with reference to FIGS. 6 and 7 .

One or more suction pipe crushers 112 are installed inside the suction pipe 110 to crush foreign substances such as fallen leaves sucked in through the suction pipe 110 and to strengthen suction pressure.

The suction pipe crusher 112 finely crushes foreign substances such as fallen leaves that are sucked in while rotating in order to achieve the above object, and the suction pipe crushing blade 1121 and the suction pipe crushing blade 1121 to generate suction pressure are rotated It includes a suction pipe rotating body 1122, and a suction pipe fixing frame 1123 for fixing and installing the suction pipe rotating body 1122 inside the suction pipe 110.

Here, the suction pipe crushing blade 1121 is preferably made of a hard material, such as a metal material, in order to effectively crush foreign substances and not be damaged.

In addition, the suction pipe rotating body 1122 is composed of a motor that moves by electric power, and is driven through electric energy provided from the power source 213 , or when the power source 213 uses fuel, the rotating body A separate component such as a battery for operating the 1122 may be further included in the power source 213 .
