Description

Multiple vacuum cleaner having multiple cleaner modes

The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner.

Vacuum cleaner is a device that sucks air and filters foreign substances such as dust from inside the main body. In general, a vacuum cleaner includes a main body in which a fan motor for generating suction force is built, a suction nozzle for suctioning foreign substances and air from the bottom surface, and a dust collecting device for filtering foreign substances. In the present specification, the vacuum cleaner is called a cleaner for convenience.

In general, various types of cleaners may be provided according to a cleaning environment or a cleaning habit of a user.

Up-right cleaners and canister cleaners are ideal for cleaning a wider range of areas with strong suction and stick cleaners for easy cleaning of narrow areas. In addition, a handy cleaner may be suitable for easy cleaning of a very narrow place, sofa, car, or bedding.

Such types of cleaners may appear due to differences in suction power, differences in portable or cleaner operation ease, and differences in power cord connection.

For example, upright cleaners and canister cleaners have very high cleaning efficiencies due to their strong suction power. However, for this reason, the weight and size of the cleaner are increased, and thus the operation is relatively difficult. In addition, there is a problem inconvenient use due to the power cord connection.

Stick cleaners have a built-in cleaning module on the stick itself. The weight or size of the cleaning module is also related to the suction power, which may increase when the power cord is connected. However, it is inconvenient to use due to the power cord connection, and there is a problem in that it is inconvenient to use because the weight and size increase. Of course, there is a stick cleaner having a relatively weak suction power and easy to use by omitting the power cord, but such a stick cleaner has a problem of low cleaning efficiency. This is because the use of a battery is weak suction power and difficult to use continuously.

Handy cleaners can be easily cleaned by a user by hand, but are difficult to clean a large cleaning area, and have a problem in that continuous use is difficult.

Therefore, generally, a plurality of cleaners are provided in a home, and a specific cleaner is often used as needed. For example, the canister cleaner and the handy cleaner may be provided, or the handy cleaner and the stick cleaner may be provided. Of course, all three cleaners may be provided.

If a plurality of cleaners are provided, since each cleaner has a separate power cord, battery or charging device, handling or storage may not be easy. Of course, it can be expensive to purchase a plurality of cleaners. And, when you want to clean, it may take a lot of effort to find the desired cleaner. In fact, it is difficult to find a suitable cleaner at the time of cleaning, which may cause a problem of using an inappropriate cleaner.

In addition, many homes are basically equipped with only canister cleaners. In this case, a bulky and canister cleaner that requires a power connection must be used for simple cleaning, which is inconvenient.

Therefore, it is necessary to provide a new type of cleaner in consideration of the cleaning efficiency, the cleaning target, the cleaning area, and the user's convenience.

The present invention basically aims to solve the problems of the above-described conventional cleaners.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention;

1 illustrates a concept of a composite cleaner according to an embodiment of the present invention.

1A shows a handy cleaner, FIG. 1B shows a stick cleaner and FIG. 1C shows a canister cleaner. As shown, according to an embodiment of the present invention, a composite cleaner combined a handy cleaner and a stick cleaner, a composite cleaner combined with a stick cleaner and a canister cleaner, and a composite cleaner combined with a handy cleaner, stick cleaner and a canister cleaner May be provided.

The handy cleaner is a small vacuum cleaner having a suction port 210 on one side and a handle 220 on the other side. The user lifts the handy cleaner through the handle 220 and faces the inlet 210 at the cleaning position for cleaning. The handy cleaner may be the same as or similar to a typical handy cleaner. However, as described below, the stick cleaner 300 may be a part of the configuration. In addition, the sub cleaning module may be provided.

The stick cleaner is a cleaner provided with a suction nozzle 310 on one side and a handle 320 on the other side. Holding the handle 200 to clean the suction nozzle to the ground in the user standing state. Therefore, the user can be cleaned without bending the waist is convenient. The stick cleaner may be the same as or similar to a general stick cleaner. However, as described below, the canister cleaner 10 may be a part of the composite cleaner. In addition, the sub cleaning module may be provided.

The canister cleaner may include a main body 100, a connection hose 150, and a stick 300. The main cleaning module is provided in the main body 100, and the user may grasp the handle 320 provided in the stick 300 and perform cleaning through the suction nozzle 310. Dust introduced through the suction nozzle 310 is introduced into the main body 100 through the stick 300 and the connection hose 150.

Therefore, since the user uses the stick similarly to the stick cleaner, the user can perform the cleaning without bending the waist. In addition, since the main cleaning module having a strong suction force is used, the cleaning efficiency can be improved.

In addition, the user pulls the connection hose 150 while operating the stick. At this time, the main body 100 is moved through the wheel provided in the main body 100. Therefore, a wider area can be easily cleaned through a strong suction force.

The canister cleaner may be the same as or similar to a general canister cleaner. However, as described below, unlike a canister cleaner having a single cleaner mode, the canister cleaner may be deformed into at least one of a stick cleaner and a handy cleaner. In other words, the canister cleaner 10 according to the present embodiment may implement a stick cleaner and a handy cleaner as well as a general canister cleaner. That is, a canister cleaner may be implemented as a main cleaner, a stick cleaner may be implemented as a sub cleaner, or a cleaner cleaner in which a stick cleaner and a handy cleaner may be implemented as a sub cleaner.

Hereinafter, the stick of the stick cleaner 300 or the composite cleaner (canister cleaner) will be described in detail with reference to FIG. 2.

The stick cleaner 300 may be implemented by detaching the stick 300 of the complex cleaner 10 illustrated in FIG. 1C from the connection hose 150. That is, when the connection hose 150 and the stick 300 are connected, the stick 300 simply forms a path for moving dust, but when the connection hose 150 and the stick 300 are separated, the stick 300 is independent. The cleaner may be converted to the stick cleaner 300.

The stick cleaner 300 includes a stick body 301. One side of the stick body 3010 is provided with a suction nozzle 310 and the other side is provided with a handle 320.

The stick main body 301 may be provided with a sub cleaning module, and the sub cleaning module may include a sub motor to be described later. That is, in order to clean independently of the main body 100 described above, a sub cleaning module independent of the main cleaning module provided in the main body 100 is provided. Similarly, the main cleaning module may include a main motor described later.

The sub cleaning module may be provided to be embedded in the stick body 301. That is, the stick body 301 itself may be one cleaner. Of course, as will be described later, the sub cleaning module may be detachably provided to the stick body 301. For example, the sub-cleaning module may be provided in the handy cleaner 200. More specifically, the handy cleaner main body 201 may accommodate the sub cleaning module.

As shown in FIG. 3, the stick body 301 may be provided with a first flow path 330 and a second flow path 340. In detail, the first passage 330 and the second passage 340 may be provided inside the stick body 301.

In addition, the stick body 301 may be provided with a first connection part 350 for connecting the connection hose 150 shown in FIG. 1C.

When the connection hose 150 is connected to the first connector 350, the stick body 301 performs a stick function of the canister cleaner. When the connection hose 150 is separated from the first connection part 350, the stick body 301 performs a stick cleaner function. Therefore, the stick cleaner and the canister cleaner may be selectively implemented depending on whether the connection hose 150 is connected to the stick body 301. That is, a composite cleaner in which the canister cleaner mode (main cleaner mode) and the stick cleaner mode may be selectively performed depending on whether the connection hose is connected to the stick body may be provided.

The first passage 330 communicates the suction nozzle 310 with the first connection portion 350. Therefore, in the canister cleaner mode, dust is sequentially introduced into the suction nozzle 310, the first passage 330, the first connection portion 350, the connection hose 150, and the main body 100.

The second passage 340 communicates the suction nozzle 310 and the handy cleaner 200. That is, the second flow path 340 communicates the suction nozzle 310 and the sub cleaning module provided in the main body 201 of the handy cleaner 200. Therefore, in the stick cleaner mode, dust is sequentially introduced into the suction nozzle 310, the second passage 340, and the handy cleaner body 201.

The first channel and the second channel are selectively opened according to the cleaner mode. That is, in the canister cleaner mode, the first flow path is opened and the second flow path is closed. In the stick cleaner mode, the second channel is opened and the first channel is closed. At least two dampers 331 and 341 may be provided to selectively open and close the first flow path and the second flow path. The second flow path may be branched from the first flow path.

In general, cleaning is performed through suction force in the cleaner. Due to this suction force, the operation of the damper can be controlled according to the position of the suction force generation source. Of course, the position of the damper may also be determined in consideration of the position of the suction force generation source.

The first channel 330 may be provided with a first damper 331. The first damper 331 may be provided at a point where the second flow path 340 is branched from the first flow path 330 or more biased to the first connection portion 350 than the point. By the suction force generated in the main body 100, the first damper 331 may be opened to overcome its own weight. Accordingly, dust may be sequentially introduced through the suction nozzle 310 and the first connector 350 to perform the canister cleaner mode.

The second channel 330 may be provided with a second damper 341. The second damper 341 may be provided in the suction part 210 of the handy cleaner body 201, or may be provided in the second flow path 330 and the suction part 210, respectively.

The second damper 341 is opened by the suction force generated by the handy cleaner body or the sub suction module. Therefore, dust may be sequentially introduced through the suction nozzle 310 and the second connector 340 to perform the stick cleaner mode.

The dampers 331 and 341 may be formed in a flip shape. By generating suction force, the flip weight can be overcome and the flip can be moved to open the flow path. If the suction force is not generated, the flow path can be closed by the weight of the flip.

On the other hand, when the second damper 341 is provided only in the suction unit 210, in the canister cleaner mode, the handy cleaner 200 should always be coupled to the stick body 301. This is because, when the coupling is released, air may be sucked through the second passage as well as the suction nozzle 310. In this case, when using the canister cleaner, a problem may arise in that the user always takes the weight of the handy cleaner 200 additionally.

Therefore, when using the canister cleaner, it may be said that the handy cleaner 200 can be separated from the stick body 301. To this end, the second damper 341 is preferably provided on the second passage 340 as well as the suction unit 210. Specifically, the second damper 341a may be further provided at a point where the second flow path is branched from the first flow path. The added second damper 241a may be closed when the suction force is generated in the main body 100 and open when the suction force is generated in the handy cleaner body 201.

4 illustrates an operating state of the flow paths and the dampers in the stick cleaner mode. In the stick cleaner mode, the first damper 331 closes the first flow path by its own weight, and the second damper 341 may be operated to open the second flow path by the suction force.

5 illustrates an operating state of the flow paths and the dampers in the canister cleaner mode. In the canister cleaner mode, the second damper 341 closes the second passage by its own weight and the first damper 331 may be operated to open the first passage 330 by the suction force.

On the other hand, if the second damper 341 shown in FIG. 5 is removed and the handy cleaner 200 is separated from the stick body 301, the second flow path may be in communication with the atmosphere. In this case, air is introduced not only through the suction nozzle 310 but also through the second flow path, so that the canister cleaner mode may not be performed smoothly.

Therefore, it is preferable that a second damper for selectively opening and closing the second passage is further provided on the second passage 340. The added second damper 341a may be formed at a point where the second flow passage 340 is branched from the first flow passage 330. The second damper 341a closes the second channel 340 by its own weight and the suction force through the first channel, and the second damper 341a is closed by the suction force through the second channel 340. It may be operable to open the two euros 340.

Through the second damper 341 and the second damper 341a added, the canister cleaner mode may be performed even when the handy cleaner 200 is separated from the stick body 301. Thus, the user can easily perform the canister cleaner mode through the lighter stick.

Of course, a cover or lid may be provided to separately close the second flow path 340 without the addition of the second damper 341a. That is, the handy cleaner 200 may be separated from the stick body 301, and a cover or lead may be separately provided to close the second flow path 340. Through this, even if the handy cleaner 200 is separated from the stick body 301, it will be able to perform the canister cleaner mode.

Hereinafter, the stick cleaner mode and the handy cleaner mode will be described in detail with reference to FIG. 6.

As shown, the sub-cleaning module may be provided inside the handy cleaner 200. Since the sub cleaning module is combined with the stick body 301, the stick cleaning can be performed. Of course, the sub cleaning module may not be separated, as shown in FIG. 6. In this case, it may not be possible to implement the handy cleaner 200. That is, only the stick cleaner mode and the canister cleaner mode may be performed. Therefore, the handy cleaner 200 is manufactured to be easily coupled to and detached from the stick main body 301, thereby enabling three cleaner modes to be performed through one composite cleaner.

Specifically, the handy cleaner main body 201 accommodates the sub cleaning module, and the main body 201 may be detachably provided to the stick main body 301.

The handy cleaner main body 201 may be provided with a sub-motor 202 (see FIG. 8) for generating a suction force. In addition, a battery 204 for supplying power to the sub-motor 202 may be provided.

The main body 201 may be provided with a sub input unit 230, and the user may operate the sub input unit 230 to perform cleaning through the handy cleaner mode.

The sub input unit 230 may be provided for a user input including power application and release of the sub motor 202. Of course, the input for adjusting the suction force may also be included in the user input. Through the user input through the sub input unit 230, the sub controller 203 may control the operation of the handy cleaner.

Therefore, when the handy type cleaner body 201 is separated from the stick body 301, one handy type cleaner 200 may be implemented by itself.

Here, the sub cleaning module may include the above-described sub-motor 202, and may include a dust box or a dust separation device (not shown). The dust separator can be implemented with a simple filter or with a cyclone device using the cyclone principle. The details of such a sub cleaning module are not the main aspects of the present invention, so further description thereof will be omitted.

The handy cleaner body 201 may be seated on the cleaner seating portion 330 of the stick body 301 and may be coupled to the stick body 301. In this case, the stick body 301 may be referred to as a stick cleaner independent of the main body 100. Of course, it can be said that the stick cleaner is implemented using the sub cleaning module of the handy cleaner 200.

When the handy cleaner body 201 is coupled to the stick body 301, not only mechanical coupling between the two but also electrical connection is required. Of course, the air needs to be combined to communicate with each other.

To this end, the seating portion 330 may be provided with a second connector 340. The suction port 210 of the handy cleaner main body 201 may be positioned in the second connector 340 to communicate with each other. Through this, sequential inflow of dust into the suction nozzle 310, the stick body 301, and the suction port 210 is possible.

Here, a separate main input unit 380 may be provided for the manipulation of the stick cleaner 300 using the handy cleaner 200. Of course, the operation of the stick cleaner 300 may be performed through the above-described sub input unit 230.

However, for cleaning through the stick cleaner 300, the user grasps the handle 320 provided in the stick body 301. Therefore, the main input unit 380 is preferably provided in the handle 320 separately from the sub input unit 230.

The main input unit 380 may be provided for a user input including power application and release of the sub-motor 202. Of course, it will be possible to adjust the suction force of the sub-motor 202 through the main input unit 380.

Here, it can be seen that the stick main body 301 and the handy cleaner main body 201 need to be electrically connected to each other in order to apply power to and release the sub-motor 202 through the main input unit 380.

In detail, the seating part 330 may be provided with a third connection part 390. When the handy cleaner body 201 is coupled to the stick body 301 through the seating portion 330, the third connection portion 390 may be provided such that both are electrically connected to each other.

In this case, it is not preferable that both the main input unit 380 and the sub input unit 230 are electrically connected to the sub-motor. Therefore, when the handy type cleaner body 201 is coupled to the stick body 301, the third connector 390 may be provided to block electrical connection between the sub input unit 230 and the sub motor 202. Do.

Therefore, the manipulation control of the handy cleaner through the sub input unit 230 is limited, while the stick cleaner may be implemented through the manipulation control of the handy cleaner through the main input unit 230.

Meanwhile, the third connector 390 may be provided for mechanical coupling of the handy cleaner body 201 and the stick body 301. Of course, it can also be configured as an additional connection separately from the electrical connection. Mechanical coupling may be implemented through a hook structure or the like.

In order to facilitate mechanical coupling and release between the two, the handy cleaner type 201 or the stick body 301 may be provided with a button 360. By pressing the button 360, the mechanical coupling between the two can be easily released. For example, pressing the button 360 may be implemented to move the hook in the disengagement direction. If the button is not pressed, the hook may be implemented to move in the engagement direction.

6 illustrates an example in which the button 360 is provided in the stick body 301, but unlike the illustrated figure, the handy type cleaner main body 201 may be provided. In addition, it will be possible to be modified to a lever structure instead of a button.

Hereinafter, referring to FIG. 7, the connection of the stick body 301 and the connection hose 150 for the canister cleaner mode will be described in detail.

The stick body 301 may be provided with a first connection portion 350 for connecting the connection hose 150. The first connection unit 350 may be provided for electrical connection as well as mechanical connection between the two and air communication.

When the connection hose 150 is coupled to the stick body 301, the first connection part 350 allows electrical connection with the main input part 380 and the main body 100. Therefore, the user can perform the canister cleaner mode through the operation of the main input unit 380.

When performing the canister cleaner mode, the connection hose 150 extends from the first connector 350 to the main body 100. The user may manipulate the main body 100 to move by pulling the connection hose 150 while performing cleaning by holding the handle 320.

However, in order to store the cleaner after cleaning, it is preferable to arrange the connection hose 150. To this end, a hose seating portion 305 may be formed in the stick body 301. The hose seating portion 305 may be formed in the stick body 301 in the longitudinal direction. The hose seat 305 may be formed at the rear of the stick body 301.

The connection hose 150 is preferably a flexible hose. Therefore, the connection hose 150 may be in close contact with the hose seat 305. Therefore, storage of the composite cleaner 10 becomes very easy. This state is shown in FIG. 1C.

In addition, the hose seat 305 may be provided with a hose holder 306 so that the connection hose 150 is in close contact with the hose seat 305. When the connection hose 150 is inserted into the hose holder 306, the connection hose 150 may be prevented from being separated from the stick body 301.

On the other hand, the hose seating portion 305 may be formed to extend upward to the rear of the handle (320). The handle 320 may be formed in an annular shape for easy operation of the user. Therefore, the hose seating portion 305 may extend to a portion of the handle along the length direction of the stick body 301.

Hereinafter, with reference to FIG. 8, the electrical connection and disconnection of the composite cleaner 10 according to the embodiment of the present invention will be described in detail. 8 is a block diagram of the composite cleaner 10.

First, the main body 100 may include a power supply device 101, a main control unit 102, and a main motor 103. The power supply device 101 may include a power cord not shown, and may receive power from the outside through the power cord and apply it to the main motor 103. Therefore, it can be said that the main cleaning module is provided in the main body 100. The main cleaning module may include the main motor 103, and may further include a dust box or a dust separator, not shown.

The main controller 102 may control the operation of the canister cleaner by controlling operations of the power supply device 101 and the main motor 103. The main motor 103

The stick cleaner 300 may be provided with a main input unit 370. Therefore, through the operation of the main input unit 370, the power supply or release of the main motor 103 may be performed and the canister cleaner mode may be performed.

The sub cleaning module may be provided in the stick cleaner 300. That is, the sub cleaning module including the sub motor 202 may be mounted on the stick cleaner 300. However, in order to implement the handy cleaner 200, the sub cleaning module may be separated from the stick cleaner 300. To this end, the handy cleaner 200 is provided with a sub-cleaning module, by separating the handy cleaner 200 from the stick body 301, it is possible to perform the handy cleaner mode.

The handy cleaner 200 may include a sub motor 202, a sub controller 203, and a battery 204. The battery may be provided to apply power to the sub-motor. In addition, the handy cleaner 200 is preferably provided with a sub input unit 230.

As shown in FIG. 8, three cleaning modes may be performed through the two cleaning modules 103 and 202. In addition, three cleaning modes may be performed through the two input units 370 and 230.

Here, the handy cleaner mode and the stick cleaner mode may be performed using the sub cleaning module 202, and the canister cleaner mode may be performed through the main cleaning module 103.

In addition, the handy cleaner mode may be performed through the sub input unit 230, and the stick cleaner mode and the canister cleaner mode may be performed through the main input unit 370.

Specifically, in the canister cleaner mode, the battery 204 and the power supply 101 may be electrically connected to each other through the d line through the connection of the first connector 350. Therefore, the battery 204 can be charged through the connection of the first connector 350.

In addition, the main controller 102 and the main input unit 370 may be electrically connected to each other through the c line through the connection of the first connector 350. Therefore, it is possible to operate the main motor 103 through the main input unit 370.

On the other hand, it is preferable that the b line for electrically connecting the main control unit 102 and the sub control unit 203 through the connection of the first connection unit 350 is blocked. This is to prevent the operation of the sub-motor 202 through the main control unit 102 to be controlled. Of course, as will be described later, if the handy cleaner 200 is separated from the stick body 301, the electrical connection through the b-line may be automatically cut off.

Specifically, in the stick cleaner mode, when the first connection unit 350 is uncoupled, electrical connection between the stick body 301 and the main body 100 is blocked. That is, the electrical connection through the d-line and the c-line can be said to be blocked. On the contrary, when the coupling of the first connector 350 is released, it is preferable that an electrical connection is made between the main input unit 370 and the sub controller 203 through the b line. That is, it can be said that the d-line blocked by the coupling of the first connection unit 350 is connected again by disconnection.

Therefore, it is possible to operate or control the operation of the sub cleaning module through the main input unit 370. Through this, it becomes possible to perform the stick cleaner mode. Of course, at this time, the handy cleaner body 201 is coupled to the stick body 301 through the third connector 390.

As described above, it is preferable that the operation or control of the sub cleaning module through the sub input unit 230 is not performed in the stick cleaner mode. Therefore, in the connection through the third connector 390, a line for electrical connection between the sub input unit 230 and the sub controller 203 is preferably blocked. That is, when the third connector 390 is connected, the a line is preferably electrically blocked. Therefore, the main input unit may control the operation of the sub cleaning module through the b line. On the other hand, since a line connecting the sub input unit 230 and the sub control unit 203 is blocked, the operation control of the sub cleaning module through the operation of the sub input unit 230 may be blocked.

In the handy cleaner mode, the connection through the third connector 390 is released. In this release, the a line may be electrically connected again. Therefore, the operation of the sub cleaning module can be controlled through the sub input unit 230. Thus, one independent handy cleaner can be implemented.

On the other hand, the handy cleaner mode may be parallel to the canister cleaner mode. For example, when the connection of the third connector 390 is released and the connection of the first connector 350 is completed, both the handy cleaner mode and the canister cleaner mode may be performed.

As described above, the disconnection of the third connector 390 and the connection of the first connector 350 leave only the electrical connection between the main input unit and the main body 100. Therefore, it is possible to perform the canister cleaner mode using the stick in a state where the handy cleaner is separated.

This means that not only three cleaner modes may be performed in one composite cleaner 10 but also at least two cleaner modes may be simultaneously performed. In addition, it means that canister cleaning can be performed through a lighter stick.

Therefore, it is convenient to use and the cleaning mode can be selected more flexibly according to the cleaning environment.

Hereinafter, another embodiment according to the present invention will be described with reference to FIG. 9.

The composite cleaner according to the present embodiment may be the same as or similar to the above-described embodiment. However, the connection structure between the stick body 3010 and the connection hose 150 may be different.

Basically, the composite cleaner according to the present embodiment may be referred to as reducing the length of the first passage 330 described above. In the above-described embodiment, the first passage 330 may extend to the handle 320, but in this embodiment, the length of the first passage 330 may be significantly reduced.

In other words, since the first passage 330 does not extend to the upper portion or the handle of the stick body 301, the thickness of the upper portion and the handle of the stick body 301 may be significantly reduced. This means a reduction in the weight and size of the stick body, thus facilitating handling and use.

To this end, the first connection portion 350 to which the connection hose 150 and the stick body 301 are connected may be formed near the central portion of the stick body 301. In addition, the first connector 350 may be formed at the rear of the position where the handy cleaner 200 is mounted.

In this case, the connection hose 150 extends from the first connection part 350 and is connected to the main body 100. Therefore, a phenomenon in which the connection hose 150 is dragged to the bottom surface in the canister cleaner mode may occur. This is because, in the canister cleaner mode, the user grabs the handle 320 while standing and cleans, since the height of the first connection part 350 is relatively low, and thus the connection hose 150 extending long may be dragged to the bottom surface. to be.

Therefore, the connection hose 150 preferably extends along the length direction of the stick body 301 in the first connection portion 350. Preferably, it extends upwards to the vicinity of the handle 320.

To this end, the connection hose 150 may include a first connection hose 151, a second connection hose 152 and a third connection hose 153. The first connection hose 151 is a part connected to the stick body 301 through the first connection part 350, and the third connection hose 153 is a part connected to the main body 100.

When the first connection hose 151 is connected to the stick body 301, it is preferable that the first connection hose 151 extends upward in close contact with the stick body 301. The second connection hose 152 is provided between the first connection hose 151 and the third connection hose 153 so that the connection hose 150 can be moved flexibly.

If the stick cleaner 300 shown in FIG. 9 is moved from the main body 100 to the left side, the third connection hose 153 floats in the air in an oblique form. That is, due to the first connection hose 151, one end (part connected with the second connection hose 152) of the third connection hose 153 may be located higher from the ground. In other words, the first connection hose 151 substantially increases the height of the connection hose 150 extending from the stick body 301 to the main body 100. Therefore, although the position of the first connector 350 in the present embodiment is lower than that of the first connector 350 in the above-described embodiment, substantially the same effect can be expected.

Of course, according to this embodiment, the thickness and weight of the handle and the stick body, the effect of reducing the length of the flow path, the center of gravity is more concentrated under the stick, and the effect of forming a smooth flow path at the first connection portion 350 You can expect

This is because the first connection part 350 may be formed in parallel with the longitudinal direction of the stick body 350 as shown in FIG. 9.
