Description

Technical Field

[0001] The present disclosure relates to the field of cleaning devices, and in particular, to a cleaning device. Background Art

[0002] A cleaning device composed of an upright vacuum cleaner and a base station is known. When the container of the upright vacuum cleaner is full or the cleaning work is completed, the upright vacuum cleaner can be engaged with the base station to suck the dirt in the container of the upright vacuum cleaner into the container of the base station. In this way, the problem of frequent dirt dumping can be solved.

[0003] The upright vacuum cleaner of some cleaning devices includes an upright main body and a detachable hand-held suction unit. According to needs, the operator can choose to use the whole upright vacuum cleaner for cleaning, or use the hand-held suction unit alone for cleaning, such as cleaning furniture, window sills, etc. This detachable structure can improve the flexibility of use. However, such a cleaning device has the problem of inconvenient use. Summary of the Invention

[0004] In view of this, the present disclosure provides a cleaning device, aiming to solve the problem of inconvenient use of the cleaning device.

[0005] The cleaning device provided by the present disclosure includes a vacuum cleaner and a base station. The vacuum cleaner can be operably engaged and separated from the base station. The vacuum cleaner includes an upright main body and a hand-held suction unit mounted thereon. The hand-held suction unit can be detached from the upright main body to perform cleaning work alone. The hand-held suction unit has a dirt outlet, and the base station has a dirt inlet. When the vacuum cleaner is engaged with the base station, the dirt outlet and the dirt inlet are aligned to form a dirt discharge channel from the hand-held suction unit to the base station, and the hand-held suction unit and the base station are respectively at least partially located on opposite sides of the upright main body to allow the operator to detach the hand-held suction unit from the upright main body from one of the sides.

[0006] For traditional cleaning devices, if the hand-held suction unit is to be detached from the upright main body, the vacuum cleaner needs to be separated from the base station first, which causes inconvenient use. According to the cleaning device provided by the present disclosure, when the vacuum cleaner is engaged with the base station, the operator can detach the hand-held suction unit from the upright main body, which makes the detachment of the hand-held suction unit no longer conditional on the separation of the vacuum cleaner from the base station, thus simplifying the steps of detaching the hand-held suction unit and improving the convenience of use.

[0007] In a possible implementation, when the vacuum cleaner is engaged with the base station, the base station is located on the first side of the upright main body, and the hand-held suction unit is allowed to move relative to the upright main body to the second side opposite to the first side to be detached from the upright main body.

[0008] According to this configuration, during the process of detaching the handheld suction unit from the upright main body, the first side where the base station is located is opposite to the direction of the second side from which the handheld suction unit is removed. Accordingly, the movement path for removing the handheld suction unit will not interfere with the base station, making the operation of removing the handheld suction unit more convenient.

[0009] In a possible implementation, the upright main body includes a receiving portion provided with a receiving space, and at least a part of the handheld suction unit is received in the receiving space, and the receiving space is open to the second side.

[0010] Since at least a part of the handheld suction unit is received in the receiving space, when the handheld suction unit is installed on the upright main body, the overall vacuum cleaner can have a smaller size in the front-rear direction. At the same time, since the receiving space is open to the second side, the handheld suction unit will be able to move toward the second side and leave the receiving space to be detached from the upright main body.

[0011] In a possible implementation, the handheld suction unit includes a first handle, and at least a part of the first handle is located outside the receiving space and at least a part of it is located on the second side of the upright main body.

[0012] According to this configuration, when installing or detaching the handheld suction unit, the operator can hold the first handle without or with less need to insert the hand into the receiving space. Additionally, according to this configuration, the operator's hand can complete the installation or disassembly operation without passing through the receiving space. Accordingly, this configuration helps to improve the operation convenience.

[0013] In a possible implementation, the receiving space is open to the first side and the second side.

[0014] Since the receiving space is open to both the first side and the second side, the receiving portion of the upright main body will have a hollowed-out structure. In this way, on the one hand, the handheld suction unit can be directly engaged with the base station located on the first side of the receiving space, and on the other hand, it can move in the second direction to be detached from the upright main body.

[0015] In a possible implementation, at least a part of the handheld suction unit is located outside the receiving space and at least a part of it is located on the first side of the upright main body, and the base station is provided with a receiving recess for receiving the handheld suction unit.

[0016] According to this configuration, the receiving recess of the base station can receive the part of the handheld suction unit located on the first side of the upright main body, so that when the vacuum cleaner is engaged with the base station, the overall cleaning device can have a smaller size in the front-rear direction, which is beneficial to the compactness of the cleaning device structure.

[0017] In a possible implementation, the cleaning device further includes a locking mechanism and an operating member. The locking mechanism releasably fixes the handheld suction unit to the upright main body. The operating member is operated to release the locking mechanism so that the handheld suction unit is disengaged from the upright main body.

[0018] When the locking mechanism locks the handheld suction unit to the upright main body, the handheld suction unit is fixed to the upright main body and used as a whole. When the locking mechanism is released, the handheld suction unit is disengaged from the upright main body to allow the handheld suction unit to be detached from the upright main body and the handheld suction unit to be used alone.

[0019] In a possible implementation, the handheld suction unit includes a first handle. The first handle is close to the operating member so that an operator can operate the operating member while holding the first handle with one hand.

[0020] According to this configuration, the operator can use the same hand to operate the operating member to release the locking mechanism while holding the first handle. In this way, the operator can complete the operation of detaching the handheld suction unit from the upright main body with one hand.

[0021] In a possible implementation, the upright main body sequentially includes a second handle, a receiving portion, and a floor brush from top to bottom, and the handheld suction unit is installed in the receiving portion.

[0022] When the upright vacuum cleaner is used as a whole, the handheld suction unit is installed in the receiving portion, and the operator can hold the second handle and press the floor brush against the surface to be cleaned for cleaning operations.

[0023] In a possible implementation, the upright main body has a through hole, and the opening size of the through hole is larger than the dirt outlet and the dirt inlet so that the dirt outlet can be aligned with the dirt inlet through the through hole.

[0024] According to this configuration, when the vacuum cleaner is engaged with the base station, the dirt outlet can be aligned with the dirt inlet through the through hole, thereby forming a dirt discharge channel from the handheld suction unit to the base station.

[0034] Numerous specific details are set forth herein to provide a deep understanding of the overall structure, function, and use of the embodiments described in the specification and shown in the drawings. Well-known operations, components, and elements have not been described in detail so as not to make the description in the specification overly redundant. The reader will understand that the embodiments described and shown herein are non-limiting examples, and thus it can be recognized that the specific structural and functional details disclosed herein may be representative and illustrative. Without departing from the scope of the claims, these embodiments may be modified and changed.

[0035] An embodiment of the present disclosure provides a cleaning device 100. Referring to Figure 1A and Figure 1B , the cleaning device 100 may include a vacuum cleaner 10. The vacuum cleaner 10 may be an upright vacuum cleaner. Compared with a horizontal vacuum cleaner, the upright vacuum cleaner is more lightweight and easier to store. Combining Figure 1C and 1D , the vacuum cleaner 10 may include an upright main body 11 and a handheld suction unit 12 mounted thereon. The operator can use the entire vacuum cleaner 10 for cleaning operations.

[0036] The handheld suction unit 12 can be detached from the upright main body 11 to perform cleaning work independently. The handheld suction unit 12 has a smaller volume compared to the entire vacuum cleaner 10. Therefore, the handheld suction unit 12 can be used to complete some more delicate cleaning tasks, such as cleaning furniture, window sills, etc. This detachable design improves the flexibility of the cleaning device 100.

[0037] By way of example only, the handheld suction unit 12 may include a first suction source 1201 and a first container 1202. Whether the vacuum cleaner 10 is used for the overall cleaning operation or the handheld suction unit 12 is used alone for the cleaning operation, the first suction source 1201 generates a suction airflow to suck dirt into the first container 1202. The present disclosure does not particularly limit the first suction source 1201 as long as it can generate a suction airflow. For example, the first suction source 1201 may be a blower, which may include an impeller and a motor for driving the impeller to rotate.

[0038] Continuing to refer to FIGS. 1A to Figure 1D , the cleaning device 100 may further include a base station 20. The vacuum cleaner 10 may be engaged with the base station 20 to form Figure 1A the state shown, and may be separated from the base station 20 to form Figure 1B the state shown. The base station 20 may provide a function of transferring dirt. For example, when the first container 1202 of the vacuum cleaner 10 is full or the cleaning work is completed, the operator may engage the vacuum cleaner 10 with the base station 20 and transfer the dirt in the vacuum cleaner 10 to the base station 20. This can solve the problem of frequently dumping the dirt in the vacuum cleaner 10, thereby improving the cleaning efficiency.

[0039] By way of example only, the base station 20 may include a second suction source 201 and a second container 202. When transferring dirt, the second suction source 201 generates a suction airflow to suck dirt from the first container 1202 into the second container 202. The present disclosure also does not particularly limit the second suction source 201 as long as it can generate a suction airflow. For example, the second suction source 201 may also be a blower, which may also include an impeller and a motor for driving the impeller to rotate.

[0040] Continuing to refer to FIGS. 1A to Figure 1D , the handheld suction unit 12 may have a dirt outlet 121 communicating with the first container 1202, and the base station 20 may have a dirt inlet 21 communicating with the second container 202. When the vacuum cleaner 10 is engaged with the base station 20, the dirt outlet 121 can be aligned with the dirt inlet 21 to form a dirt discharge channel from the handheld suction unit 12 to the base station 20. At the same time, when the vacuum cleaner 10 is engaged with the base station 20, the handheld suction unit 12 and the base station 20 are respectively at least partially located on opposite sides of the vertical main body 11, allowing the operator to remove the handheld suction unit 12 from the vertical main body 11 from one side, that is, from Figure 1A the state shown to Figure 1D the state shown.

[0041] Regarding traditional cleaning equipment, if one wants to remove the handheld suction unit 12 from the vertical main body 11, it is necessary to first separate the vacuum cleaner 10 from the base station 20, which causes inconvenience in use. According to the cleaning equipment 100 provided by the present disclosure, when the vacuum cleaner 10 is engaged with the base station 20, the operator can remove the handheld suction unit 12 from the vertical main body 11, which makes the removal of the handheld suction unit 12 no longer conditional on the separation of the vacuum cleaner 10 from the base station 20, thereby simplifying the steps of removing the handheld suction unit 12 and improving the convenience of use.

[0042] Reference Figure 1A and Figure 1D , when the vacuum cleaner 10 is engaged with the base station 20, the base station 20 can be located on the first side of the vertical main body 11, and the handheld suction unit 12 is allowed to move relative to the vertical main body 11 to the second side opposite to the first side and be removed from the vertical main body 11. According to this configuration, during the process of removing the handheld suction unit 12 from the vertical main body 11, the first side where the base station 20 is located is in the opposite direction to the second side where the handheld suction unit 12 moves out. Accordingly, the movement path of removing the handheld suction unit 12 will not interfere with the base station 10, making the operation of removing the handheld suction unit 12 more convenient.

[0043] It should be noted that in the drawings of the present disclosure, the direction in which the vacuum cleaner is engaged with or separated from the base station is the front-back direction, and the arrow X+ and the arrow X- are respectively used to indicate the opposite sides of the front-back direction. Specifically, the first side indicates the direction close to X-, and the second side indicates the direction close to X+. The direction perpendicular to the ground is the up-down direction, and the arrow Z+ and the arrow Z- are respectively used to indicate the upper side and the lower side of the up-down direction. It should also be noted that the orientation descriptions such as "up", "down", "front", "back", etc. are relative rather than absolute. When the elements in the present disclosure are in the placement posture and placement position shown in the figure, these orientation descriptions are applicable.

[0044] It should also be noted that although in the above example, the handheld suction unit 12 moves relative to the vertical main body 11 to the second side and is removed from the vertical main body 11, in other examples of the present disclosure, the handheld suction unit 12 can also be removed from the vertical main body 11 by other means. The handheld suction unit 12 can move in any direction relative to the vertical main body 11 and be removed from the vertical main body 11, where the any direction can be parallel to or at a certain angle with the first side and the second side. For example, in one example, the handheld suction unit 12 can also move relative to the vertical main body 11 to the first side and be removed from the vertical main body 11. In one example, the handheld suction unit 12 can also move to the left and right sides of the vertical main body 11 and be removed from the vertical main body 11. Another example, in another example, the handheld suction unit 12 can also move upward and be removed from the vertical main body 11.

[0045] Reference Figure 1A and Figure 2 ,The vertical main body 11 may include a receiving portion 111, and the receiving portion 111 may be provided with a receiving space 112, and the receiving space 112 may be open to the second side. When the hand-held suction unit 12 is mounted on the vertical main body 11, the hand-held suction unit 12 may be at least partially received in the receiving space 112. Since the hand-held suction unit 12 is at least partially received in the receiving space 112, when the hand-held suction unit 12 is mounted on the vertical main body 11, the entire vacuum cleaner 10 may have a smaller size in the front-rear direction. At the same time, since the receiving space 112 is open to the second side, the hand-held suction unit 12 will be able to move toward the second side and leave the receiving space 112 to be detached from the vertical main body 11.

[0046] The shape of the receiving space 112 may have many forms, and the present disclosure does not particularly limit this. As an example, reference Figure 2 ,When viewed in the front-rear direction, the lower part of the receiving space 112 is generally rectangular, and the upper part gradually narrows inward as it goes upward, and the overall shape is adapted to the outer contour line of the hand-held suction unit 12.

[0047] Reference Figure 1A 、 Figure 1D and Figure 2 ,The hand-held suction unit 12 may include a first handle 122. When the hand-held suction unit 12 is mounted on the vertical main body 11, the first handle 122 is at least partially located outside the receiving space 112 and at least partially located on the second side of the vertical main body 11. According to this configuration, when mounting or detaching the hand-held suction unit 12, the operator can hold the first handle 122 without or with less need to insert the hand into the receiving space 112. In addition, according to this configuration, the operator's hand can complete the mounting or dismounting operation without passing through the receiving space 112. Accordingly, this configuration helps to improve the operation convenience.

[0048] The first handle 122 may be configured in many forms, and the present disclosure does not particularly limit this. As an example, reference Figure 1D, the first handle 122 may include a first grip portion 122a and a second grip portion 122b. The first grip portion 122a may be entirely disposed below the second grip portion 122b. The first grip portion 122a may extend substantially downward from the lowermost end of the second grip portion 122b. The second grip portion 122b extends in the front-rear direction and gradually rises toward the rear side. The first grip portion 122a and the second grip portion 122b may be rod-shaped and continuously formed to form a gap 123. The gap 123 may provide space for the operator's hand to grip the first grip portion 122a or the second grip portion 122b. For example, when the handheld suction unit 12 needs to be used alone, the operator may first grip the first grip portion 122a to take out the handheld suction unit 12. During the cleaning process using the handheld suction unit 12, the operator may grip the first grip portion 122a or the second grip portion 122b.

[0049] Reference Figure 1D and Figure 2 , in a particular example, the receiving space 112 is open to the first side and the second side. Since the receiving space 112 is open to both the first side and the second side, the receiving portion 111 of the upright main body 11 will have a hollow structure. In this way, on the one hand, the handheld suction unit 12 can be directly engaged with the base station 20 located on the first side of the receiving space 112, and on the other hand, it can move in the second direction to be detached from the upright main body 11.

[0050] Reference Figure 1A and Figure 3 , the handheld suction unit 12 may be at least partially located outside the receiving space 112 and at least partially located on the first side of the upright main body 11. The base station 20 is provided with a receiving recess 22 for receiving the handheld suction unit 12. For example, the receiving recess 22 may extend in the up-down direction and be recessed toward the second side. According to this configuration, the receiving recess 22 of the base station 20 can receive the portion of the handheld suction unit 12 located on the first side of the upright main body 11, so that when the vacuum cleaner 10 is engaged with the base station 20, the overall cleaning device 100 can have a smaller size in the front-rear direction, which is beneficial to the compactness of the structure of the cleaning device 100.

[0051] Reference Figure 2, the cleaning device 100 may further include a locking mechanism 13 and an operating member 14. The locking mechanism 13 releasably fixes the handheld suction unit 12 to the upright main body 11. The operating member 14 can be operated to release the locking mechanism 13 so that the handheld suction unit 12 is detached from the upright main body 11. When the locking mechanism 13 locks the handheld suction unit 12 to the upright main body 11, the handheld suction unit 12 and the upright main body 11 are fixed together and used as a whole. When the locking mechanism 13 is released, the handheld suction unit 12 is detached from the upright main body 11, allowing the handheld suction unit 12 to be removed from the upright main body 11 and used alone.

[0052] There are many ways to implement the locking mechanism 13, and the present disclosure does not make special restrictions. As an example, referring to Figure 2 , the locking mechanism 13 may include a locking tongue 131 and a locking hole 132. The locking tongue 131 can extend downward from the top of the receiving space 112, and the locking hole 132 can be recessed downward from the top of the handheld suction unit 12. When the locking mechanism 13 is in the locked state, the locking tongue 131 is inserted into the locking hole 132 to fix the handheld suction unit 12 to the upright main body 11. The operator can operate the operating member 14 to cause the locking tongue 131 to withdraw from the locking hole 132 to release the locking mechanism 13, so that the handheld suction unit 12 is detached from the upright main body 11. Alternatively, in other examples, the locking hole 132 can be recessed upward from the top of the receiving space 112, and the locking tongue 131 can extend upward from the top of the handheld suction unit 12.

[0053] It should be noted that although in the above example, the locking mechanism 13 is implemented as a combination of a locking tongue 131 and a locking hole 132, in other examples of the present disclosure, the locking mechanism 13 can also be implemented in other forms. For example, it can be implemented in a magnetic attraction manner. It should also be noted that although in the above example, the operating member 14 is provided on the handheld suction unit 12, an example where the operating member 14 is provided on the upright main body 11 is foreseeable.

[0054] For the convenience of operation, continuing to refer to Figure 2 , the first handle 122 can be close to the operating member 14 so that the same hand of the operator can operate the operating member 14 while holding the first handle 122. According to this configuration, the operator can use the same hand to operate the operating member 14 to release the locking mechanism while holding the first handle 122. In this way, the operator can complete the operation of removing the handheld suction unit 12 from the upright main body 11 with one hand.

[0055] The present disclosure does not make special restrictions on the structure of the upright main body 11. As an example, referring to Figure 2 and Figure 4, the vertical main body 11 may sequentially include a second handle 113, a receiving portion 111, and a floor brush 114 from top to bottom. When the upright vacuum cleaner 10 is used as a whole, the handheld suction unit 12 is installed on the receiving portion 111, and the operator can hold the second handle 113 and place the floor brush 114 on the surface to be cleaned for cleaning operations.

[0056] It should be understood that there are various implementation manners of the cleaning device of the present disclosure and should not be construed as limited to the embodiments described above. The following refers to Figure 5 , and the cleaning devices provided in other embodiments of the present disclosure are illustrated by way of example. It should be noted that the above embodiments and the following embodiments have some common elements. In the following embodiments, these elements will use the same reference numerals as those in the above embodiments to omit repeated descriptions.

[0057] The cleaning device 100a according to another embodiment of the present disclosure is shown in Figure 5 . Referring to Figure 5 , in the cleaning device 100a, the receiving space 112a can be implemented as a recessed space 112a that is recessed toward the first side and only open to the second side. That is to say, in the cleaning device 100a, the vertical main body 11a is not in a hollow structure. The handheld suction unit 12 can be at least partially received in the recessed space 112a. When the handheld suction unit 12 needs to be used alone, the operator can move the handheld suction unit 12 toward the second side to remove it.

[0058] Furthermore, continuing to refer to Figure 5 , the vertical main body 11a may have a through hole 115, and the through hole 115 may extend from the receiving space 112a toward the first side to penetrate the vertical main body 11a. The opening size of the through hole 115 may be larger than the dirt outlet 121 and the dirt inlet 21, so that the dirt outlet 121 can be aligned with the dirt inlet 21 through the through hole 115. According to this configuration, when the vacuum cleaner 10 is engaged with the base station 20, the dirt outlet 121 can be aligned with the dirt inlet 21 through the through hole 115, thereby forming a dirt discharge channel from the handheld suction unit 12 to the base station 20.

[0059] It should be understood that the term "including" and its variants used in the present disclosure are open-ended inclusions, that is, "including but not limited to". The term "according to" means "at least partially according to". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least another embodiment".

[0060] It should be understood that although terms such as "first" or "second" may be used in the present disclosure to describe various elements (such as the first handle and the second handle), these elements are not defined by these terms, and these terms are only used to distinguish one element from another.

[0061] The protection scope of the present disclosure is not limited to the above embodiments. Any person skilled in the art can conceive of changes or substitutions within the technical scope disclosed by the present disclosure, and all such changes or substitutions should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
