Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and specifically to a multifunctional cleaning device. Background Technology

[0002] Currently, most cleaning tools on the market have relatively simple functions. For example, brooms are generally used to sweep up small debris on relatively flat surfaces. When the ground is not flat, such as when collecting fallen leaves scattered on the lawn, brooms are not very suitable. In this case, other cleaning tools are needed. That is, when different cleaning functions are required, multiple cleaning tools are often needed, which is neither convenient to carry nor easy to store. Utility Model Content

[0003] To address at least one of the aforementioned problems, according to one aspect of the present invention, a multifunctional cleaning device is provided.

[0004] The multi-functional cleaning device includes a handle; and a first cleaning unit, a second cleaning unit, and a hair dryer integrated on the handle; wherein the first cleaning unit and the second cleaning unit have different cleaning functions.

[0005] Therefore, different cleaning needs can be met by using a first cleaning unit and a second cleaning unit with different cleaning functions on the same multi-functional cleaning device. Lighter items can also be cleaned by using a blower, which improves the portability and cleaning efficiency of the cleaning device while making it easier to store.

[0006] In some embodiments, the first cleaning unit and the second cleaning unit are disposed on the first side of the handle. This ensures the compact structure of the multi-functional cleaning device.

[0007] In some embodiments, the second cleaning unit is mounted on the handle via a first moving unit. The first moving unit is configured to drive the second cleaning unit to reciprocate between a first position and a second position relative to the first cleaning unit along a first direction. The first direction is parallel to the second cleaning unit. When the second cleaning unit is in the first position, the free end of the second cleaning unit is located inside the first cleaning unit; when the second cleaning unit is in the second position, the free end of the second cleaning unit is located outside the first cleaning unit.

[0008] Therefore, the first moving unit can drive the second cleaning unit to reciprocate between a first position (the first cleaning unit is in the working position, and the second cleaning unit is in the non-working position) and a second position (the first cleaning unit is in the non-working position, and the second cleaning unit is in the working position) relative to the first cleaning unit, so that the second rake and the first broom are alternately in the working position, avoiding mutual interference between the second rake and the first broom when they are in the working position; especially when the second rake and the first broom are set parallel to each other, it is convenient to realize that the second rake moves smoothly relative to the first broom along the first direction.

[0009] In some embodiments, the hair dryer is located on the second side of the handle. This ensures the compactness of the multi-functional cleaning device; moreover, when the first and second cleaning units are located on the first side of the handle and the hair dryer is located on the second side of the handle, interference between the cleaning units and the hair dryer can be avoided.

[0010] In some implementations, the first cleaning unit includes a broom. Thus, when it is necessary to sweep up small debris on a relatively flat surface, a broom can be used.

[0011] In some embodiments, the second cleaning unit includes a rake. Thus, when it is necessary to clean uneven ground, such as sweeping fallen leaves on a lawn, the rake can be used; and when this multi-functional cleaning device is equipped with both a broom and a rake, it can be adapted to cleaning needs in different scenarios.

[0012] In some implementations, the rake and broom are arranged parallel to each other. This ensures the compactness of the structure of the multi-functional cleaning device.

[0013] In some embodiments, the rake is mounted on the handle via a first moving unit, which is configured to drive the rake to reciprocate relative to the broom between a first position and a second position along a first direction. The first direction is parallel to the rake. In the first position, the free end of the rake is located inside the broom, and in the second position, the free end of the rake is located outside the broom.

[0014] Therefore, the first moving unit can drive the rake to reciprocate between a first position (the broom is in the working position and the rake is in the non-working position) and a second position (the broom is in the non-working position and the rake is in the working position) relative to the broom, so that the rake and the broom alternately are in the working position, avoiding mutual interference between the rake and the broom when they are in the working position; especially when the rake and the broom are set in parallel, it is easy to realize that the rake moves smoothly relative to the broom along the first direction.

[0015] In some embodiments, the multi-functional sweeping device also includes a locking unit capable of locking the rake relative to the broom. Thus, when the rake moves relative to the broom to the desired position, the locking unit can lock the rake relative to the broom, for example, ensuring the broom is stably in a first or second position, thereby ensuring the broom or rake is stably in the working position. Furthermore, when the handle is a rod, it can also serve as a guide rod for the first moving unit, and can keep its first and second sides away from each other, preventing the first and second cleaning units located on the first side from interfering with the blower located on the second side.

[0016] In some embodiments, the handle is a rod arranged along a first direction. This ensures the compactness of the structure of the multi-functional cleaning device.

[0017] In some embodiments, the rake includes at least two rake teeth, the included angle of which gradually increases from the second side of the handle to the first side of the handle, the rake teeth are made of a deformable material, and the broom is provided with first through holes through which the rake teeth pass, and the plane formed by the axes of all the first through holes is arranged parallel to a first direction.

[0018] Therefore, when the rake is needed, the rake teeth can be moved to the second side away from the handle to expand the rake by increasing the distance between the free ends of the rake teeth; when the rake is not needed, the rake teeth can be moved to the second side of the handle to retract the rake by decreasing the distance between the free ends of the rake teeth, so as to maintain the compactness of the structure when the rake is not in use, making it easy to store and carry this multi-functional cleaning device.

[0019] In some embodiments, the end of the rake teeth near the free end of the broom is bent away from the broom. This prevents the rake teeth from moving out of the first through hole.

[0020] In some embodiments, the first cleaning unit also includes a scraper. This allows the scraper to remove dirt and other contaminants from the ground.

[0021] In some embodiments, the broom includes a first connector and a broom body connected to the first connector, with at least one of a first through hole and a scraper body disposed on the first connector. This ensures the compact structure of the multi-functional cleaning device.

[0022] In some embodiments, the scraper and the rake are positioned on the same side of the broom, with the scraper positioned on the side of the rake away from the broom, and the free end of the scraper away from the broom located outside the rake. This prevents the rake, in its primary position, from interfering with the use of the scraper.

[0023] In some implementations, the air outlet of the hair dryer is positioned away from the first side of the handle. This ensures the effective blowing of the hair dryer.

[0024] In some implementations, the sweeper is made of a deformable material. This prevents the sweeper from obstructing the scraper and rake during cleaning.

[0025] In some implementations, the hair dryer is equipped with a speed control switch for adjusting the speed. This allows the airflow speed to be adjusted as needed.

[0026] In some embodiments, the hair dryer includes a rechargeable battery, and the rechargeable battery is arranged along a first direction. This ensures the compactness of the structure of the multi-functional cleaning device. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] Figures 1 to 10 The multifunctional cleaning device according to the first embodiment of the present invention is shown schematically.

[0046] like Figure 1 , Figures 4 to 7 and Figure 10 As shown, the multi-functional cleaning device includes a handle 20, a rake, a blower 33, a broom 311, and a scraper 312. The rake, blower 33, broom 311, and scraper 312 are integrated on the handle 20.

[0047] In some embodiments, continue to refer to Figure 1 , Figures 4 to 7 and Figure 10 The broom 311 and the scraper 312 constitute the first cleaning unit 31 of one embodiment of this application.

[0048] In some embodiments, continue to refer to Figure 1 , Figures 4 to 7 and Figure 10 The rake constitutes a second cleaning unit 32 in one embodiment of this application, so that the formed second cleaning unit 32 has different cleaning functions from the first cleaning unit 31.

[0049] When carrying out cleaning work, different cleaning needs can be met by using the first cleaning unit 31 and the second cleaning unit 32 with different cleaning functions on the same multi-functional cleaning device, even with only one device. For example, the broom 311 in the first cleaning unit 31 can be used to sweep small debris on relatively flat ground, or the scraper 312 in the first cleaning unit 31 can be used to scrape away dirt or chewing gum on relatively flat ground, or the rake in the second cleaning unit 32 can be used to sweep uneven ground, such as sweeping fallen leaves on the lawn. The blower 33 can also be used to sweep lighter items, so as to improve the portability and cleaning efficiency of the cleaning device while making it easy to store.

[0050] As one embodiment of the broom 311 integrated into the handle 20, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 10 As shown, the broom 311 includes a first connector 3111 and a broom body 3112 connected to the first connector 3111. The first connector 3111 is connected to the handle 20. The broom 311 can also adopt the form of broom 311 commonly used in the prior art.

[0051] In some embodiments, to ensure the compactness of the structure of the multifunctional cleaning device, such as Figure 1 and Figures 4 to 7 As shown, the first cleaning unit 31 and the second cleaning unit 32 are disposed on the first side 21 of the handle 20.

[0052] In some embodiments, to ensure the compactness of the structure of the multifunctional cleaning device, reference continues to be made. Figure 1 and Figures 4 to 7 The hair dryer 33 is located on the second side 22 of the handle 20. Moreover, when the first cleaning unit 31 and the second cleaning unit 32 are located on the first side 21 of the handle 20 and the hair dryer 33 is located on the second side 22 of the handle 20, the cleaning units and the hair dryer 33 can be prevented from interfering with each other.

[0053] In some embodiments, to ensure the compactness of the structure of the multifunctional cleaning device, such as Figure 1 , Figure 5 and Figure 7 As shown, the rake and broom 311 are arranged parallel to each other. In this application, parallelism is not strictly defined; as long as the included angle between the two is within 10°, it is considered parallel in the sense of this application. The parallel arrangement of the rake and broom 311 means that the plane containing the rake body is parallel to the plane containing the broom body 3112 of the broom 311.

[0054] In some embodiments, such as Figure 1 , Figures 4 to 7 and Figure 10 As shown, the handle 20 is a rod extending along the first direction X, such that the first side 21 and the second side 22 of the handle 20 are located on opposite sides of the handle 20. When the first cleaning unit 31 and the second cleaning unit 32 are respectively arranged on the first side 21 and the second side 22 of the handle 20, the compact structure of the multi-functional cleaning device can be ensured while ensuring that the first cleaning unit 31 and the second cleaning unit 32 do not interfere with each other. Preferably, the rod is a telescopic rod.

[0055] In some embodiments, such as Figure 1 , Figures 3 to 5 , Figure 7 , Figure 9 and Figure 10 As shown, the rake is mounted on the handle 20 via a first moving unit 40. The first moving unit 40 is configured to drive the rake to reciprocate between a first position and a second position relative to the broom 311 along a first direction X. The first direction X is parallel to the rake. In the first position, the free end of the rake is located inside the broom 311 (i.e., the distance between the free end of the rake and the second side 22 of the handle 20 is less than the distance between the free end of the broom 311 and the second side 22 of the handle 20; at this time, the broom 311 is in a usable state (working state) and can be used for sweeping, while the rake is in a retracted state). In the second position, the free end of the rake is located outside the broom 311 (i.e., the distance between the free end of the rake and the second side 22 of the handle 20 is greater than the distance between the free end of the broom 311 and the second side 22 of the handle 20; at this time, the broom 311 is in a retracted state, while the rake is in a usable state (working state) and can be used for sweeping). In this application, parallelism is not in the strict sense; any angle within 10° is considered parallel in the sense of this application.

[0056] As one embodiment of the first moving unit 40, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figure 10As shown, the first moving unit 40 includes a guide rail 41 and a slider 42 that are adapted to each other. The guide rail 41 is the rod of the handle 20, so that the slider 42 can reciprocate along the extension direction of the handle 20 (i.e., the first direction X). A rake is disposed on the slider 42. As one embodiment of the slider 42, the slider 42 is a sleeve fitted on the outer periphery of the rod. As another embodiment of the first moving unit, the first moving unit includes a smooth rod and an outer tube that are adapted to each other. The outer tube is fitted on the smooth rod and can serve as a handle, so that the outer tube can reciprocate along the extension direction of the smooth rod (e.g., the first direction X); a rake can be disposed on the outer tube. The first moving unit 40 can also adopt other implementations in the prior art, and this application does not limit the specific implementation of the first moving unit 40.

[0057] When using this multi-functional sweeping device, the first moving unit 40 can drive the rake to a first position relative to the broom 311 (the broom 311 is in the working position, and the rake is in the non-working position, such as...). Figure 1 , Figures 4 to 7 (As shown) reciprocating motion between the second and third positions (broom 311 is in the non-working position, rake is in the working position, as shown) Figure 10 As shown), so that the rake and broom 311 alternate in the working position, avoiding mutual interference between the rake and broom 311 when they are in the working position; especially when the rake and broom 311 are set in parallel, it is convenient to realize the smooth movement of the rake relative to the broom 311 along the first direction X.

[0058] In some embodiments, such as Figure 1 , Figures 3 to 5 , Figure 7 , Figure 9 and Figure 10 As shown, the multi-functional sweeping device also includes a locking unit 50 capable of locking the rake relative to the broom 311.

[0059] As one embodiment of the locking unit 50, such as Figure 7 and Figure 9As shown, the locking unit 50 includes a handle 51 rotatably disposed on the first moving unit 40, and a positioning hole 52 fixedly disposed relative to the handle 20. Specifically, the handle 51 is disposed on the slider 42. When the handle 51 is rotated relative to the slider 42 to the locked position, the handle 51 can fit into the positioning hole 52 to prevent the slider 42 from moving relative to the handle 20, thereby preventing the second cleaning unit 32 from moving relative to the first cleaning unit 31; when the handle 51 is first rotated relative to the slider 42 to the unlocked position, the handle 51 can be moved out of the positioning hole 52, so that the slider 42 can move relative to the guide rail 41. Preferably, the locking unit 50 also includes an elastic element, and the elastic element is configured such that when the handle 51 moves from the locked position to the unlocked position, the elastic force of the elastic element needs to be overcome so that the handle 51 can be stably in the locked position without the action of external force.

[0060] The locking unit 50 can also be implemented in other ways in the prior art. This application does not limit the specific implementation of the locking unit 50.

[0061] When using this multi-functional sweeping device, when the rake moves relative to the broom 311 to the desired position, the locking unit 50 can lock the rake relative to the broom 311. For example, it can ensure that the broom 311 is stably in the first position or the second position, thereby ensuring that the broom 311 or the rake is stably in the working position. Moreover, when the handle 20 is a rod, it can also serve as a guide rod for the first moving unit 40, and can keep its first side 21 and second side 22 away from each other, so as to avoid the first cleaning unit 31 and the second cleaning unit 32 set on the first side 21 from interfering with the blower 33 set on the second side 22.

[0062] As one embodiment of the scraper body 312 being integrated into the handle 20, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 10 As shown, the scraper 312 and the rake are positioned on the same side of the broom 311, with the scraper 312 positioned on the side of the rake away from the broom 311. The free end of the scraper 312, away from the broom 311, is located outside the rake. Specifically, this prevents the rake in its first position from interfering with the use of the scraper 312. Preferably, the scraper 312 is positioned on the first connector 3111 of the broom 311 to ensure the compactness of the multi-functional cleaning device.

[0063] As one embodiment of a rake, such as Figure 1 , Figures 4 to 7 and Figure 10As shown, the rake includes at least two rake teeth 321, the included angle of which gradually increases from the second side 22 of the handle 20 to the first side 21 of the handle 20. The rake teeth 321 are made of a deformable material, such as stainless steel or plastic. The broom 311 is provided with first through holes 3111a through which the rake teeth 321 pass. The plane formed by the axes of all the first through holes 3111a is parallel to the first direction X, and each rake tooth 321 passes through one first through hole 3111a. Preferably, as Figure 1 , Figure 5 and Figure 7 As shown, the first through hole 3111a is integrally formed or machined on the first connector 3111 to ensure the compactness of the structure of the multifunctional cleaning device.

[0064] When the rake is needed, the rake teeth 321 can be moved away from the second side 22 of the handle 20 to expand the rake by increasing the distance between the free ends of the rake teeth 321. Figure 10 (Structure shown); When the rake is not needed, the rake teeth 321 can be moved toward the second side 22 of the handle 20 to achieve rake retraction (forming) by reducing the distance between the free ends of the rake teeth 321. Figure 1 , Figure 4 and Figure 6 The structure shown is designed to maintain its compactness when the rake is not in use, making it easy to store and carry this multi-functional cleaning device.

[0065] In some embodiments, such as Figure 1 As shown, the rake includes a second connector 322 in addition to the rake teeth 321; one end of the rake teeth 321 is connected to the slider 42 through the second connector 322.

[0066] In some embodiments, the end of the rake tooth 321 near the free end of the broom 311 is bent away from the broom 311, that is, the bent rake tooth 321 is nearly perpendicular to the broom body 3112 of the broom 311; at this time, if the scraper body 312 is present, the scraper body 312 is also nearly perpendicular to the broom body 3112. Thus, the rake tooth 321 can be prevented from moving out of the first through hole 3111a.

[0067] In some preferred embodiments, the sweeping body 3112 is made of a deformable material, such as nylon, PET (polyethylene terephthalate) plastic filaments, to avoid the sweeping body 3112 obstructing the scraper body 312 and the rake from cleaning.

[0068] In some embodiments, such as Figure 1 and Figure 7As shown, the air outlet 331 of the hair dryer 33 is positioned away from the first side 21 of the handle 20 to avoid the first cleaning unit 31 and the second cleaning unit 32 affecting the blowing effect of the hair dryer 33.

[0069] In some embodiments, such as Figure 1 , Figure 2 , Figures 5 to 8 As shown, the hair dryer 33 is equipped with a speed control switch 332 for adjusting the speed as needed.

[0070] In some embodiments, such as Figure 7 and Figure 8 As shown, the hair dryer 33 includes a rechargeable battery 333, and the rechargeable battery 333 is arranged along the first direction X to ensure the compactness of the structure of the multi-functional cleaning device.

[0071] In some embodiments, such as Figure 1 As shown, the hair dryer 33 is also equipped with a main switch 335.

[0072] In some embodiments, such as Figure 1 As shown, the hair dryer 33 is also provided with an air inlet 336, which is located on the side away from the air outlet 331.

[0073] In some embodiments, such as Figure 1 As shown, the blower 33 is positioned along the extension direction of the rod-shaped handle 20 to maintain the compactness of the structure of the multi-functional cleaning device.

[0074] In some embodiments, such as Figure 7 and Figure 8 As shown, the hair dryer 33 also includes a motor 337, the motor 337 and the rechargeable battery 333 are arranged along the first direction X, and the air inlet 336 and the air outlet are located at both ends of the motor 337, so as to maintain the compact structure of the multi-functional cleaning device.

[0075] A multi-functional sweeping device according to a second embodiment of the present invention. The main difference between this and the first embodiment of the multi-functional sweeping device is that this multi-functional sweeping device does not include a broom 311.

[0076] In some embodiments, the scraper 312 constitutes a first cleaning unit 31 of one embodiment of this application.

[0077] A multi-functional cleaning device according to a third embodiment of the present invention. The main difference between this and the first embodiment of the multi-functional cleaning device is that this multi-functional cleaning device does not include a scraper body 312.

[0078] In some embodiments, the broom 311 constitutes a first cleaning unit 31 in one embodiment of this application.

[0079] In some embodiments, the scraper constitutes a second cleaning unit according to one embodiment of this application.

[0080] Figures 11 to 13 The diagram schematically illustrates a multi-functional cleaning device according to a fourth embodiment of the present invention. Its main difference from the first embodiment of the multi-functional cleaning device lies in the specific implementation of the locking unit 50. For example... Figures 11 to 13 As shown, the locking unit 50 in this embodiment does not include a handle 51 and a positioning hole 52, but includes a knob 53 and a bolt 54; the bolt 54 is fixedly disposed relative to the knob 53 and is threadedly connected to the slider 42. By rotating the knob 53, the bolt 54 moves relative to the slider 42, and by controlling the direction of the movement of the bolt 54 relative to the slider 42, the slider 42 is locked and unlocked relative to the guide rail 41.

[0081] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0082] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
