The present invention relates to a modular vacuum cleaner, and more particularly, to a modular vacuum cleaner capable of changing the order of connection according to use conditions by modularizing each component, or selecting and combining only necessary components for use.

A vacuum cleaner is a device that performs cleaning by sucking or wiping dust or foreign substances in an area to be cleaned.

Such cleaners may be classified into manual cleaners for cleaning while the user directly moves the cleaner, and automatic cleaners for cleaning while driving themselves.

In addition, manual cleaners may be classified into canister-type cleaners, upright-type cleaners, handheld cleaners, stick-type cleaners, and the like, depending on the shape of the cleaner.

Korean Patent Publication No. 2016-0026122 (hereinafter referred to as 'Patent Document 1') discloses a handheld vacuum cleaner. The handheld vacuum cleaner disclosed in Patent Document 1 is composed of a suction nozzle, a vacuum cleaning unit, an extension pipe assembly, and a handle.

The vacuum cleaning unit is provided with a suction motor generating suction force and a dust container, and is connected to a handle.

The vacuum cleaner disclosed in Patent Document 1 corresponds to a vacuum cleaner having a center of gravity at an upper tooth located on the handle side since a vacuum cleaning unit equipped with a suction motor is integrally formed with a handle portion.

In this way, the vacuum cleaner having the center of gravity at the upper teeth has inconvenience in applying a weight burden to the user due to a large moment load being applied when cleaning the floor.

Accordingly, in Chinese Patent Publication No. 110432820 (hereinafter referred to as 'Patent Document 2') and Korean Patent Publication No. 2020-0098571 (hereinafter referred to as 'Patent Document 3'), configurations capable of changing the center of gravity of the vacuum cleaner are disclosed. there is. That is, it is configured so that the user can change the position of the suction module equipped with the motor.

That is, the user can change to one of the two centers of gravity, the center of gravity of the upper value and the center of gravity of the lower value.

However, when configured as in Patent Document 2, there is a problem in that the flow path structure becomes complicated because the internal flow path must be varied according to the position fastened to the suction module.

And, in Patent Document 3, the suction module is configured to slide and move in the longitudinal direction so that the center of gravity can be changed and used. That is, the user can slide and move the suction module while fixing it at a desired position and setting it to a desired center of gravity.

However, when configured as in Patent Document 3, there is a problem in that the structure of the suction passage becomes complicated because the suction passage must be changed in response to the sliding movement of the suction module. In addition, since a rail structure for sliding the suction module has to be configured separately, the structure becomes complicated and the weight of the vacuum cleaner becomes heavy.

In addition, Korean Patent Publication No. 2018-0076257 (hereinafter referred to as 'Patent Document 4') discloses a modular wireless vacuum cleaner.

1 to 4, the modular vacuum cleaner 1 according to an embodiment of the present invention includes a body part 20 provided with a driving part providing suction power and a dust collection part for storing dirt, and a handle part gripped by a user. (30), a connection part (40) connecting each component and configured to have a hollow so that the sucked air can flow, a cleaning part (10) for contacting the cleaning object and applying physical force to the cleaning object, and the main body part ( 20) and may include a battery unit 50 for applying power to the driving unit.

The cleaning part 10, the main body part 20, the handle part 30, and the connection part 40 have unified fastening parts so that all components can be connected to each other. That is, all components are provided with coupling parts for coupling with each other.

Here, the main body part 20 and the connection part 40 are provided with female fastening parts and male fastening parts, which are coupling parts, on both sides, so that they can be fastened by changing the order of each other.

In addition, since the cleaner 10 is located at the lowermost end of the modular cleaner 1, only one female fastening part or male fastening part as a coupling part may be provided.

In addition, since the handle part 30 is located at the uppermost end of the modular cleaner 1, only one male fastening part or female fastening part as a coupling part may be provided.

That is, the cleaning part 10 and the handle part 30 are located at both ends of the modular vacuum cleaner 1, and the order in which the main body part 20 and the connecting part 40 are connected is changed so that the main body part ( 20) can be changed.

The body part 20 has a driving part 220, a dust collecting part 230, and a battery part 50, and is the heaviest in the modular vacuum cleaner 1, and the module according to the connection position of the main body part 20. The center of gravity of the vacuum cleaner 1 is changed.

Through this, the user can selectively change the position where the main body part 20 is disposed to change the center of gravity of the modular vacuum cleaner 1 according to the usage environment, thereby improving usability.

Therefore, in the modular cleaner 1 according to the embodiment of the present invention, the center of gravity of the modular cleaner 1 can be changed according to the user's convenience by changing the connection position of the body part 20 .

Hereinafter, a connection relationship between components capable of changing the center of gravity of the modular vacuum cleaner 1 according to an embodiment of the present invention will be described in more detail.

The modular vacuum cleaner 1 described below includes a cleaning unit 10, a body unit 20, a handle unit 30, a battery unit 50, and a connection unit 40. The battery unit 50 is fastened to the body unit 20 .

The connection part 40 has a hollow inside for fluid movement, and includes a coupling part for coupling with at least one of the cleaning part 10, the main body part 20, and the handle part 30.

And, when the coupling part of the connection part 40 is coupled to the cleaning part 10 or the handle part 30, the cleaning part 10 or the handle part 30 is connected to the main body through the coupling part of the connection part 40. It is electrically connected to the unit 20. That is, the connection part 40 is a component that electrically connects other components while mechanically connecting them.

The connecting portion 40 may include, for example, a first connecting portion 41 and a second connecting portion 42 having different lengths. In addition, the second connection portion 42 is shorter than the first connection portion 41 .

Of course, the configuration of the connection part 40 is not limited thereto, and a plurality of connection parts having the same length may be provided, and the connection length may be differently fastened by changing the number and order of their coupling.

3 and 4 are views showing a state in which the position of the main body part 20 is changed and fastened in the modular vacuum cleaner 1 according to the embodiment of the present invention.

Referring to (a) of FIG. 3, after the first connection part 41 and the second connection part 42 are sequentially connected to the cleaner 10, the body part 20 is connected to the second connection part 42, The handle part 30 may be connected to the main body part 20 .

Here, the order in which the first connection part 41 and the second connection part 42 are connected to each other may be changed.

In this case, the first connection part 41 and the second connection part 42 are used for the purpose of air flow and the purpose of extending the length between the cleaning part 10 and the main body part 20 .

Since the driving unit 220 and the dust collecting unit 230 are disposed inside the body unit 20 and the battery unit 50 is fastened therein, the body unit 20 is configured to have a larger diameter than other components.

In this way, when the body portion 20 having the largest diameter is located on the uppermost side, it is advantageous to clean the gap space.

For example, in the case where the cleaner 10 is inserted into a gap between the floor and the furniture in a space where furniture such as a bed or sofa is installed, the cleaner 10 must be inserted into a deeper space.

In this case, if the main body part 20 having a relatively large diameter is disposed close to the cleaning part 10, the main body part 20 prevents the cleaning part 10 from being introduced into a deeper space, thereby reducing the cleaning space. become narrower

Therefore, since the first connection part 41 and the second connection part 42 having a relatively small diameter connect the cleaning part 10 and the main body part 20, the cleaning part 10 can be inserted to the deepest space to be cleaned. can

In addition, since the driving unit 220 and the dust collecting unit 230 are disposed inside the main body unit 20 and the battery unit 50 is fastened therein, the body unit 20 is the heaviest component compared to other components.

In this way, the heaviest body portion 20 is located on the uppermost side, so it has a higher center of gravity.

In the case of using the modular cleaner 1 by connecting to the upper center of gravity, since the center of gravity is close to the user's side when the user holds and uses the modular cleaner 1, the feeling of weight in use can be reduced.

For example, when cleaning a wall, table, window frame, ceiling, etc., the user lifts the vacuum cleaner and uses it. When the center of gravity is located close to the handle part 30, the user can stably operate the vacuum cleaner. there is.

Referring to (b) of FIG. 3 , after the first connection part 41 is connected to the cleaner 10, the body part 20 is connected to the first connection part 41, and the body part 20 and the handle part are connected. (30) can be made by connecting the second connection portion (42).

In this case, the first connection part 41 is used for the purpose of air flow and the purpose of extending the length between the cleaning part 10 and the main body part 20, and the second connection part 42 is used for the purpose of extending the length between the main body part 20 ) It is used for extending the length between the handle part 30.

With this configuration, it can be used by connecting to have a middle-upper center of gravity in which the center of gravity is moved lower than the upper center of gravity described above.

In the case of the upper center of gravity, since the center of gravity is formed close to the side of the handle part 30, the feeling of weight on the side of the cleaner 10 is relatively reduced, so that the side of the cleaner 10 can be easily shaken.

In comparison, in the case of the upper middle center of gravity, since the center of gravity moves lower than the upper center of gravity, the feeling of weight is more weighted toward the cleaner 10 side, so that the moving operation on the cleaner 10 side can be more stabilized. .

In addition, when cleaning the floor, the moment load applied to the handle part 30 is greater in the vacuum cleaner connected to the upper center of gravity than the vacuum cleaner connected to the middle and upper center of gravity, so that the user can use the upper center of gravity In the case of using the connected cleaner, the handle part 30 must be held with more force.

Therefore, when the modular vacuum cleaner 1 is connected to the middle and upper center of gravity, the cleaner can be operated more lightly than the vacuum cleaner connected to the upper center of gravity, thereby improving comfort and reducing fatigue during operation.

In addition, when the user lifts and uses the vacuum cleaner when cleaning walls, tables, window frames, ceilings, etc., the user holds the main body part 20 with one hand while holding the handle part 30 with the other hand. can do the cleaning

In this case, since the user holds and operates the body part 20, which is the heaviest component, the cleaner can be operated more stably.

Of course, even in the case of the upper center of gravity, the user can hold the body part 20 with one hand while holding the handle part 30 with the other hand to clean.

Referring to (a) of FIG. 4 , after the second connection part 42 is connected to the cleaner 10, the body part 20 is connected to the second connection part 42, and the body part 20 and the handle part (30) can be made by connecting the first connection portion (41).

Here, the second connection part 42 is used for the purpose of air flow and the purpose of extending the length between the cleaning part 10 and the main body part 20, and the first connection part 41 is used for the main body part 20 And it is used for the purpose of extending the length between the handle portion (30).

With this configuration, it can be used by connecting to have a lower middle center of gravity whose center of gravity is moved lower than the upper middle center of gravity described above.

In this case, since the moment load applied to the handle part 30 is smaller than that of the cleaner connected to the upper middle center of gravity, the user exerts less force than when using the vacuum cleaner connected to the upper middle center of gravity. You can hold the handle part 30.

However, since the center of gravity is located close to the cleaning unit 10, in order for the user to twist the handle unit 30 and rotate the cleaning unit 10 to a desired position, more force is required than a cleaner connected to a middle and upper center of gravity. will do

Therefore, the upper middle center of gravity and the lower middle center of gravity can be connected to a center of gravity where the user can feel more comfortable according to the user's physical condition and the cleaning environment.

Referring to (b) of FIG. 4 , after the main body part 20 is directly connected to the cleaning part 10, and the first connection part 41 and the second connection part 42 are sequentially connected to the body part 20, The handle part 30 may be connected to the second connection part 42 .

Here, the order in which the first connection part 41 and the second connection part 42 are connected to each other may be changed.

Also, the first connection part 41 and the second connection part 42 are used to extend the length between the body part 20 and the handle part 30 .

With this configuration, it can be used by connecting to have a lower center of gravity whose center of gravity is moved lower than the middle and lower center of gravity described above.

In this case, since the moment load applied to the handle part 30 is smaller than that of the cleaner connected to the middle and lower center of gravity, the user exerts less force than when using the cleaner connected to the middle and lower center of gravity. You can hold the handle part 30.

However, since the center of gravity is positioned close to the cleaning unit 10, more force is required than a cleaner connected to a middle or lower center of gravity to rotate the cleaning unit 10 to a desired position by twisting the handle unit 30 by the user. will be needed

Therefore, the middle and lower center of gravity and the lower center of gravity can be connected to a center of gravity where the user can feel more comfortable according to the user's physical condition and the cleaning environment.

Furthermore, since more load can be applied to the cleaner 10 in the case of a lower center of gravity, as shown in FIG. 8, the cleaner 10 equipped with a cleaning mop 190 capable of wiping the floor surface When used, the cleaning effect can be enhanced.

That is, while rotating, the cleaning mop 190 comes into contact with the floor, which is an object to be cleaned, and wipes the floor. Since it rotates in close contact with the surface, the cleaning performance of wiping the floor can be further improved.

Here, the cleaner 10 does not have a separate suction port for sucking in air, and can be used only for wiping an object to be cleaned by attaching only the cleaning mop 190.

Alternatively, the cleaning unit 10 may be formed with a suction port for sucking air, and may be configured to additionally attach the cleaning mop 190 to clean while wiping together while sucking in dirt from the cleaning object.

As described above, the location of the center of gravity of the user's comfort while operating the vacuum cleaner may be different depending on the user's physical condition, such as the user's height and arm length, and cleaning environment conditions, such as the cleaning position and cleaning type.

Therefore, since the user can directly select the center of gravity where he can feel comfortable in operation and assemble and use each component, convenience of use can be further improved.

5 to 8 , the modular cleaner 1 according to the embodiment of the present invention uses the body part 20 and the handle part 30, but the cleaning part 10 and the first connection part 41 and The second connection unit 42 may be selectively connected and used.

In this way, the heaviest body portion 20 is located on the uppermost side, so it has a higher center of gravity.

In the case of using the modular cleaner 1 by connecting to the upper center of gravity, since the center of gravity is close to the user's side when the user holds and uses the modular cleaner 1, the feeling of weight in use can be reduced.

For example, when cleaning a wall, table, window frame, ceiling, etc., the user lifts the vacuum cleaner and uses it. When the center of gravity is located close to the handle part 30, the user can stably operate the vacuum cleaner. there is.

In addition, only the first connection part 41 or the second connection part 42 may be connected and used under conditions where it is advantageous to use a shorter vacuum cleaner, such as in a place where the user is tall or the ceiling is low.
