Description

Technical Field

[0001] This application relates to the field of cleaning tool technology, and more specifically, to an electric brush. Background Technology

[0002] As the heart of the home and dining establishment, the kitchen is a vital space for food processing, cooking, and storage. Over time, countertops easily accumulate food residue, grease, limescale, and microbial contaminants. These contaminants not only affect aesthetics but can also breed bacteria (such as Salmonella and E. coli), directly threatening food safety and human health. Furthermore, the long-term adhesion of stubborn stains can cause corrosion or discoloration of countertop materials (such as stone, wood, or composite panels), shortening their lifespan. Therefore, efficient and thorough cleaning is crucial for maintaining kitchen hygiene, protecting user health, and extending countertop durability.

[0003] Traditional kitchen cleaning methods rely primarily on manual tools (such as cloths, sponges, or ordinary brushes), but these methods have significant limitations, such as low cleaning efficiency, insufficient cleaning uniformity, and poor user experience. In contrast, electric cleaning tools, through mechanical actuation (such as rotation, vibration, or ultrasonic technology), can achieve highly efficient stain removal, better controllability, and greater user comfort.

[0004] Existing cleaning brushes typically consist of a brush head and a handle, with the handle usually being streamlined. Kitchen cleaning is a relatively tedious task, and when using existing cleaning brushes, the brush needs to be placed horizontally on the kitchen countertop frequently. This easily leads to dirt accumulating on the outer circumference of the handle, and the operator's hands are easily contaminated when holding the handle, affecting the comfort of using the cleaning brush. Utility Model Content

[0005] In view of the above-mentioned shortcomings, this application provides an electric brush to improve the problem of poor cleanliness of electric brushes in related technologies.

[0006] This application is implemented as follows:

[0007] An example of this application provides an electric brush, including a housing, a power mechanism, a brush head, and a hook. The housing has a handle portion and a head portion at its two ends along its length. The power mechanism includes a drive unit and a transmission unit. The drive unit is disposed within the handle portion and drives the transmission unit, which is disposed at the head portion. The brush head is disposed at the head portion, and the transmission unit drives the brush head to move. The hook is rotatably disposed at the end of the handle portion. The hook has a first state of contact with the handle portion and a second state of being away from the handle portion. When the hook is in the first state, the end of the handle portion has a first end face configured to allow the electric brush to be placed on a table with its head facing upwards.

[0008] When using the electric brush provided in this embodiment for cleaning, the operator can hold the handle and drive the brush head through the power mechanism to clean dirt more efficiently and evenly. Furthermore, since a rotatable hook is provided at the end of the handle, the operator can rotate the hook to adjust it to a second state where it is separated from the handle. This allows the electric brush to be suspended, reducing the likelihood of the handle directly contacting a less clean surface and improving the cleanliness of the brush during use. Alternatively, since the hook is rotatably located on the handle, the operator can also rotate it to adjust it to a first state where it contacts the handle. When the hook is adjusted to the first state, the end of the handle has a first end face, allowing the operator to place the electric brush head-up on the surface, reducing the likelihood of contact between the outer circumferential wall of the brush housing and the surface, thus improving the cleanliness of the brush housing, especially the outer circumferential wall of the handle. The good cleanliness of the brush housing, especially the outer circumferential wall of the handle, provides greater comfort for the operator when holding the handle for cleaning.

[0009] The electric brush provided in this application embodiment has a hook that can be rotatably set at the end of the handle. This not only allows the electric brush to be placed upside down on the table, but also allows it to be suspended as needed, providing a variety of placement options. Operators can more flexibly choose the appropriate way to place the electric brush, and it can also improve the cleanliness of the handle and enhance the comfort of the operator.

[0010] In one alternative embodiment, the end has a recessed area that is recessed toward the head. When the hook is in the first state, the hook is embedded in the recessed area, and the exposed surface of the hook facing the first end face is located on the side of the first end face closer to the head, or the exposed surface of the hook facing the first end face is flush with the first end face.

[0011] In the above implementation, a recessed area is provided at the end of the handle. When it is not necessary to use a hook to suspend the electric brush, the hook can be embedded in the recessed area, ensuring that the exposed surface of the hook facing the first end face does not protrude beyond the first end face. Therefore, when the electric brush is placed on a table with its head facing upwards, the hook will not cause interference and will not significantly affect the stability of the electric brush. Furthermore, embedding the hook in the recessed area can improve the integration of the electric brush and reduce its space occupancy.

[0012] In one alternative embodiment, the hook has two hinge areas and a suspension area located between the two hinge areas. The two hinge areas are respectively hinged to the region of the end near the circumferential outer wall of the handle portion, and the recessed area is located in the region of the end near the circumferential outer wall. When the hook is in a first state, the suspension area is located within the recessed area.

[0013] In the above implementation process, by hinged to the two hinge areas of the hook and the end of the handle, the position of the suspension area located between the two hinge areas can be adjusted by adjusting the rotation angle of the two hinge areas around the end of the handle. When the electric brush does not need to be suspended, the suspension area can be adjusted into the recessed area so that the electric brush can be placed on the table with its head facing upward through the first end face of the end. When suspension is required, the suspension area can be extended out of the recessed area for easy suspension. Furthermore, by hinged to the area of ​​the handle end near the circumferential outer wall of the handle with the hinge area of ​​the hook, rather than hinged to the circumferential outer wall of the handle with the hinge area of ​​the hook, excessive structures can be introduced into the circumferential outer wall of the handle, making the circumferential outer wall simpler and smoother, and further improving the operator's grip comfort.

[0014] In one alternative embodiment, the recessed area is a groove structure, with the outer groove wall flush with the circumferential outer wall. When the hook is in the first state, the suspension area is located within the groove structure.

[0015] In the above implementation process, a groove structure is provided at the end of the handle to form a recessed area. When it is not necessary to use a hook to suspend the electric brush, the hook can be accommodated in the groove structure. Furthermore, since the outer wall of the groove structure is flush with the circumferential outer wall of the handle, the circumferential outer wall of the electric brush handle can be made into a whole, and it is not easy for dirt to accumulate on the circumferential outer wall.

[0016] In one optional embodiment, the outer wall of the groove structure is provided with a U-shaped notch, and the hanging area is provided with a protrusion. When the hook is in the first state, the protrusion is located inside the U-shaped notch, and the outer end of the protrusion protrudes from the circumferential outer wall.

[0017] In the above implementation process, when it is necessary to suspend the electric brush by hook, the operator can lift the protrusion extending from the U-shaped notch to the circumferential outer wall, and drive the suspension area to rotate out of the groove through the protrusion.

[0018] In one alternative embodiment, the groove structure is interference-fitted with the suspension area. When the hook is in the first state, the hook is flush with the second end face of the outer groove wall or located on the side of the second end face of the outer groove wall closer to the head.

[0019] In the above implementation process, the interference fit between the hook's suspension area and the groove structure reduces the likelihood of unnecessary hook rotation. When it is not necessary to rotate the hook's suspension area out of the groove, the suspension area can be locked within the groove structure. When the hook's suspension area is locked within the groove, the hook is flush with the second end face of the outer groove wall or located on the side of the second end face of the outer groove wall closer to the head, which facilitates placing the electric brush on the table with the head facing upwards, improving placement stability. When it is necessary to rotate the hook out of the groove structure, simply apply force to the protrusion on the hook to rotate it out, making the operation more convenient.

[0020] In one alternative embodiment, the height of the outer groove wall of the groove structure is lower than the height of the inner groove wall of the groove structure. When the hook is in the first state, the suspension area is partially interlocked within the groove structure, and the other part of the suspension area protrudes from the outer groove wall in a direction away from the head.

[0021] In the above implementation process, the height of the outer groove wall of the groove structure is lower than the height of the inner groove wall of the groove structure. When the hook is interference-fitted into the groove structure, a part of the hook suspension area protrudes from the outer groove wall in a direction away from the head, making it convenient for the operator to contact this part to rotate the hook, so that the hook is rotated out of the groove structure and is in the second state, which facilitates the suspension of the electric brush.

[0022] In one alternative embodiment, the recessed area is an L-shaped notch. When the hook is in the first state, the suspension area is located inside the L-shaped notch, and the outer periphery of the suspension area is flush with the outer circumferential wall of the handle portion.

[0023] In the above implementation process, the recessed area is set as an L-shaped notch. When the hook is placed in the L-shaped notch, the outer periphery of the hook can be flush with the circumferential outer wall of the handle, making it convenient for the operator to contact the outer periphery of the hook and rotate the hook.

[0024] In one optional embodiment, along the first extension direction when the hook is in the first state, the two ends of the recessed area each have an end wall, and the two ends of the recessed area near the two end walls each have a hinge shaft. The two hinged areas of the hook are respectively hinged to the two hinge shafts, and when the hook rotates, the two ends of the hook can respectively contact the two end walls. Along the rotation direction of the hook, each end wall is provided with multiple limiting slots. When the hook rotates, the two ends of the hook in the extension direction can be selectively restricted within one limiting slot to adjust different rotation angles of the hook.

[0025] In the above implementation process, after the hinge area of ​​the hook is hinged to the hinge shaft near the end wall, multiple limiting slots are provided on both end walls of the recessed area corresponding to the extension direction of the hook. These multiple limiting slots are spaced apart along the rotation direction of the hook. Therefore, the two ends of the hook along its extension direction will be locked in one of the limiting slots, keeping the hook in that rotational position. When it is necessary to adjust the rotation angle of the hook, the hook can be rotated so that the two ends of the hook are locked in the other limiting slot and remain stable. This embodiment of the application provides multiple limiting slots on the end wall of the recessed area so that the hook can be fixed at different rotation angles, allowing the electric brush to match the suspension angle requirements of the suspension components in the application scenario, resulting in high suspension flexibility.

[0026] In one optional embodiment, the limiting groove is an arc-shaped groove, and arc-shaped limiting blocks are respectively provided at both ends of the hook's extension direction. When the hook rotates, the limiting blocks can be selectively confined within one limiting groove.

[0027] In the above implementation process, the limiting slot is set as an arc-shaped slot, and arc-shaped limiting blocks are set at both ends of the hook extension direction. When the hook is rotated, the arc-shaped blocks can rotate more smoothly from one arc-shaped slot to another arc-shaped slot, thereby improving the operation convenience of the electric brush.

[0028] In one alternative implementation, the two hinged areas are respectively hinged to the ends via damped hinges.

[0029] In the above implementation process, the two hinged areas of the hook are respectively hinged to the end of the handle through damping hinges. The operator can rotate the hook to different angles and keep the hook in that position. In the electric brush provided in this application embodiment, the hook has multiple rotation angles, which not only better matches the suspension angle requirements of the suspension device in the usage scenario, but also allows the hook to be stably in the first state when suspension is not required, improving the stability of the electric brush during the cleaning process and making it convenient to place the electric brush on the countertop with the head facing upwards.

[0030] In one optional embodiment, the hook is a sheet-like structure with a through hole, and the sheet-like structure is hinged to an end. When the hook is in a first state, the sheet-like structure is flush with a first end face. When the hook is in a second state, the through hole can be used for suspension.

[0031] In the above implementation process, a through hole is provided at the hook of the sheet-like structure, through which the electric brush can be suspended. Furthermore, by setting the hook as a sheet-like structure, when suspension is not required, the sheet-like structure can be rotated into the recessed area, making the sheet-like structure flush with the first end face. When the electric brush is placed on the table with its head facing upwards, the sheet-like structure can contact the table to support the electric brush, thereby improving the placement stability of the electric brush.

[0032] In one alternative embodiment, the circumferential outer wall of the handle portion is provided with a recess, and when the hook is in the first state, the hook is embedded in the recess, and the exposed surface of the hook is flush with the circumferential outer wall.

[0033] In the above implementation process, a recessed area is provided on the circumferential outer wall of the handle. When the electric brush is not needed, the hook can be embedded in the recessed area of ​​the circumferential outer wall, preventing the hook from protruding from the first end face of the handle. This makes it convenient to place the electric brush on the table with its head facing upwards. Furthermore, when the hook is in the first state, the exposed surface of the hook is flush with the circumferential outer wall of the handle. The operator can hold the circumferential outer wall of the handle and the exposed surface of the hook for cleaning, preventing the hook from turning out of the recessed area during cleaning and making the structure of the electric brush more stable during operation.

[0034] In one alternative embodiment, the housing further includes a neck located between the handle and the head. The transmission unit includes a drive shaft and a gear set, the gear set including a meshing first gear and a second gear, one end of the drive shaft being connected to the output shaft of the drive unit, and the other end being connected to the first gear. One end of the gear shaft of the second gear is rotatably connected to the head, and the other end of the gear shaft is rotatably connected to the brush head.

[0035] In the above implementation process, one end of the drive shaft is connected to the drive unit inside the handle, and the other end passes through the neck and is connected to the first gear located inside the head. The first gear meshes with the second gear, which can drive the brush head connected to the gear shaft of the second gear to rotate. By driving the brush head to rotate through the gear set, the electric brush can have weak vibration and low noise when in use. Attached Figure Description

[0052] When cleaning kitchens, bathrooms, and other similar areas, various cleaning brushes are typically used. Cleaning brushes usually have a brush head and a handle. The operator usually holds the brush head and rotates or slides it to brush away dirt from the countertop.

[0053] When cleaning countertops with existing cleaning brushes, operators often leave the brushes on the surface during or after cleaning, leading to brush contamination and consequently, operator discomfort. For example, the handles of existing cleaning brushes are typically streamlined, and when placed horizontally on the countertop, the outer circumferential wall of the handle comes into contact with the surface, allowing dirt from the countertop to contaminate the handle. Therefore, when the operator holds the brush handle again, the dirt on the outer circumferential wall of the handle will contaminate the operator, affecting their comfort.

[0054] Therefore, this application further improves the cleaning brush, thereby improving cleaning quality, enhancing the cleanliness of the brush, and improving operator comfort to a certain extent. To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0055] Please combine Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the electric brush 1 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the internal structure of the electric brush 1 provided in this application embodiment. The electric brush 1 provided in this application embodiment includes a housing 10, a power mechanism 20, a brush head 30, and a hook 40.

[0056] Please refer to Figure 1 The housing 10 has a handle portion 11 and a head portion 12 at its two ends along its length direction D1. See also... Figure 2 The power mechanism 20 includes a drive unit 21 and a transmission unit 22. The drive unit 21 is located inside the handle portion 11 and drives the transmission unit 22, which is located in the head 12. Please continue reading. Figure 1 and Figure 2 The brush head 30 is located on the head 12, and the transmission unit 22 is connected to the brush head 30 to drive its movement. Please continue reading. Figure 1 and Figure 2 The hook 40 is rotatably disposed at the end 111 of the handle portion 11. The hook 40 has a first state in contact with the handle portion 11 and a second state away from the handle portion 11. When the hook 40 is in the first state, the end 111 of the handle portion 11 has a first end face 1111, which is configured to allow the electric brush 1 to be placed on the table with its head 12 facing upwards. In this application, when the hook 40 is in the first state, the contact between the hook 40 and the handle portion 11 does not refer to indirect contact between the hinge area of ​​the hook 40 and the hinge area of ​​the end 111 connected by, for example, a hinge shaft, but rather to direct contact between the portion of the hook 40 other than the hinge area and the handle portion 11. For example, when the hook 40 is in the first state, the suspension area of ​​the hook 40 is in direct contact with the end 111 of the handle portion 11. Or, when the hook 40 is in the first state, the suspension area of ​​the hook 40 is in direct contact with the circumferential outer wall 112 of the handle portion 11.

[0057] When using the electric brush 1 provided in this embodiment for cleaning, the operator can hold the handle 11 and turn on the switch of the drive unit 21 to drive the transmission unit 22 to rotate, thereby rotating the brush head 30 to remove dirt. During the cleaning process, the operator does not need to repeatedly apply force to rotate the brush head. Furthermore, using the power mechanism 20 to drive the brush head 30 to remove dirt has the characteristics of high cleaning efficiency and good cleaning uniformity, thus improving the cleaning quality.

[0058] In addition, the electric brush 1 provided in this embodiment of the application is provided with a first end face 1111 at the end 111 of the handle portion 11. During or after cleaning, the operator can place the electric brush 1 on the table with the head 12 facing upward through the first end face 1111. When the electric brush 1 is placed vertically on the table, the first end face 1111 of the electric brush 1 contacts the table surface, so there is basically no dirt on the circumferential outer wall 112 of the handle portion 11. When the operator holds the circumferential outer wall 112 of the handle portion 11, it will not contaminate the operator's hands, thus improving the operator's comfort.

[0059] Furthermore, kitchen walls and other locations are typically equipped with hanging devices, and walls are generally cleaner than countertops. In the electric brush 1 provided in this embodiment, a rotatable hook 40 is provided at the end 111. The operator can rotate the hook 40 to a second state where the handle 11 is separated, and suspend the electric brush 1 on a wall or other location using the hook 40, further improving the cleanliness of the electric brush 1. Since the hook 40 is rotatably connected to the end 111, when not needing to be suspended, the hook 40 can be rotated to a first state where it contacts the handle 11, making the electric brush 1's external structure simpler and more stable during operation. Moreover, when the electric brush 1 is placed on the countertop with its head 12 facing upwards, the hook will not interfere, improving the placement stability of the electric brush 1.

[0060] The electric brush 1 provided in this application embodiment has multiple placement methods. It can be placed vertically on a table or hung on a wall or other locations. Operators can choose the appropriate placement method as needed, which can improve the cleanliness of the electric brush 1 and the comfort of the operator.

[0061] The following describes in further detail, with reference to the accompanying drawings, the housing 10, power mechanism 20, brush head 30 and hook 40 of the electric brush 1 provided in the embodiments of this application.

[0062] In this application, the handle portion 11 and the head 12 can be integrally connected or detachably connected separately. Both the handle portion 11 and the head 12 have internal receiving space.

[0063] This application does not limit the specific shape of the housing 10. In some embodiments, the handle portion 11 and the head 12 can be a rotating structure. As an example, the handle portion 11 and the head 12 can be cylindrical, with the axis of the head 12 intersecting the axis of the handle portion 11.

[0064] Alternatively, in other embodiments, the outer shape of the handle portion 11 and the head portion 12 can be relatively independently cylindrical, polygonal prism, frustum or polygonal frustum.

[0065] In some embodiments, the handle portion 11 has an end portion 111 on the side away from the head 12, and a circumferential outer wall 112 connected to the circumferential edge of the end portion 111. The end portion 111 has a certain thickness, and the surface of the end portion 111 on the side away from the head 12 has a first end face 1111.

[0066] In some embodiments, an opening may be provided at the head 12 so that the connecting end of the brush head 30 can extend into the head 12 and connect to the power mechanism 20.

[0067] In some embodiments, please continue reading Figure 1The housing 10 also includes a neck 13 located between the handle portion 11 and the head 12, the outer diameter of which is smaller than that of the handle portion 11 and the head 12. The handle portion 11, the neck 13 and the head 12 are smoothly transitioned. The end of the housing 10 near the head 12 is warped.

[0068] Alternatively, in some embodiments, the housing 10 may be in the form of other irregular rod-shaped structures.

[0069] In this application, end 111 refers to the shell wall of the end of the handle portion 11 away from the head 12. The shell wall has a certain thickness and is staggered with the shell 10 along its length direction D1. For example, when the handle portion 11 has a cylindrical shape, end 111 is the circular body wall of the cylindrical end away from the head 12. For example, when the handle portion 11 has a triangular prism shape, end 111 is the triangular body wall of the triangular prism end away from the head 12.

[0070] In some embodiments, the outer surface of the end 111 on the side away from the head 12 can be a complete plane or a surface with a recess, groove or other structure.

[0071] The power mechanism 20 is located inside the housing 10 and is used to drive the brush head 30 to rotate. The drive unit 21 of the power mechanism 20 is located inside the handle part 11. The drive unit 21 drives and connects to the transmission unit 22, which is located at the head 12, thereby driving the brush head 30 located at the head 12 to rotate.

[0072] This application does not limit the specific type of the power mechanism 20. In some embodiments, the drive unit 21 includes a power source and a motor electrically connected to the power source. As an example, the power source may be a battery.

[0073] Furthermore, in some embodiments, a corresponding opening may be provided on the circumferential outer wall 112 of the handle portion 11, and a switch may be provided at the opening to control the opening or closing of the drive unit.

[0074] In some embodiments, please refer to Figure 3 The transmission unit 22 includes a transmission shaft 221 and a gear set, which includes a meshing first gear 222 and a second gear 223. One end of the transmission shaft 221 is connected to the output shaft of the drive unit 21, and the other end is connected to the first gear 222. One end of the gear shaft of the second gear 223 is rotatably connected to the head 12, and the other end is rotatably connected to the brush head 30. During operation, the drive unit 21 drives the transmission shaft 221 to rotate, which in turn drives the first gear 222 to rotate. The first gear 222 then drives the meshing second gear 223 to rotate, and finally, the second gear 223 drives the brush head 30 to rotate.

[0075] In some embodiments, the housing 10 can be configured with a warped head 12, and the axial direction of the brush head 30 can be staggered with the longitudinal direction D1 of the housing 10. When using the brush head 30, the operator can hold the handle 11 laterally, allowing the brush head 30 to rotate at an angle approximately perpendicular to the table surface, thus improving the operator's comfort.

[0076] To facilitate the staggered arrangement of the axial direction of the brush head 30 with the longitudinal direction D1 of the housing 10, thus enabling the brush head 30 to rotate, in some embodiments, please refer to [the relevant documentation]. Figure 3 The first gear 222 and the second gear 223 can be configured as meshing bevel gears, wherein the gear shaft of the first gear 222 is aligned with the axial direction of the transmission shaft 221 inside the housing 10, and the axial direction of the gear shaft of the second gear 223 is perpendicular to the axial direction of the transmission shaft 221.

[0077] The brush head 30 rotates relative to the countertop, thereby removing dirt from the countertop. This application does not limit the specific type of brush head 30. In some embodiments, the brush head 30 may include a brush head holder with a rotating structure. Multiple bristle holes are provided on the end face of one end of the brush head holder along its axial direction, and multiple bristles are bonded within the bristle holes. A connecting hole is provided on the end face of the other end of the brush head holder, and a connecting shaft is spun into the connecting hole. The connecting shaft is connected to the second gear 223.

[0078] As an example, the end face of the brush head holder with the brush bristle holes is spherical. Alternatively, the end face of the brush head holder with the brush bristle holes is flat.

[0079] The hook 40 is rotatably disposed at the end 111 of the handle portion 11. When the hook 40 is not in use, it can be rotated to a first state where it contacts the handle portion 11. When the hook is in the first state, the end 111 of the handle portion 11 has a first end face 1111, and the hook 40 does not protrude beyond the first end face 1111. Therefore, the electric brush 1 can be placed on the table with its head 12 facing upwards. When hanging is required, the hook 40 is rotated to separate it from the handle portion 11, placing it in a second state.

[0080] This application does not limit how the hook 40 is rotatably disposed at the end 111 of the handle portion 11. In some embodiments, a recess may be provided at the circumferential outer wall 112 of the handle portion 11 to hinge the hook 40 to the end 111. In the first state, the hook 40 can be accommodated in the recess of the circumferential outer wall 112 (not shown in the figure).

[0081] Furthermore, when the hook 40 is accommodated within the recess of the circumferential outer wall 112, the exposed surface of the hook 40 is flush with the circumferential outer wall 112. "Exposed surface" refers to the surface of the hook 40 exposed in the recess when in the first state. The flushness of the exposed surface of the hook 40 with the circumferential outer wall 112 improves operator comfort when gripping the handle portion 11.

[0082] Alternatively, in some other embodiments, please combine Figure 4 and Figure 5 The end 111 has a recessed area 1112 that is recessed toward the head 12. When the hook 40 is in the first state, the hook 40 is embedded in the recessed area 1112, and the exposed surface of the hook 40 facing the first end face 1111 is located on the side of the first end face 1111 closer to the head 12, or the exposed surface of the hook 40 facing the first end face 1111 is flush with the first end face 1111.

[0083] "Exposed surface" refers to the outer surface of the hook 40 facing the first end face 1111 when the hook 40 is embedded in the recessed area 1112. The exposed surface being located on the side of the first end face 1111 closer to the head 12 means that the thickness of the hook 40 is less than the depth of the recessed area 1112, and the exposed surface of the hook 40 does not extend beyond the first end face 1111 and does not intersect with the first end face 1111. Along a direction perpendicular to the first end face 1111, the projection of the hook 40 is located between the projection of the first end face 1111 and the projection of the head 12, and the projection point of the side of the hook 40 facing the first end face 1111 is located on the side of the projection point of the first end face 1111 facing the head 12. When the electric brush 1 is placed on the table with the head 12 facing upwards, the exposed surface of the hook 40 does not contact the table surface, and the exposed surface of the hook 40 is higher than the table surface.

[0084] The fact that the exposed surface of the hook 40 facing the first end face 1111 is flush with the first end face 1111 means that, along a direction perpendicular to the first end face 1111, the projection point of the hook 40 facing the first end face 1111 overlaps with the projection point of the first end face 1111. The exposed surface of the hook 40 is coplanar with the first end face 1111. When the electric brush 1 is placed on the table with its head facing upwards, both the exposed surface of the hook 40 and the first end face 1111 are in contact with the table surface.

[0085] This application does not limit how the hook 40 is positioned in the recessed area 1112. In some embodiments, the recessed area 1112 is located in the region of the end 111 near the circumferential outer wall 112. Please continue reading. Figure 5 The hook 40 has two hinge areas 41 and a suspension area 42 located between the two hinge areas 41. The hinge areas 41 are hinged to the area of ​​the end 111 near the circumferential outer wall 112 of the handle portion 11.

[0086] As an example, the hook 40 can be in the form of a sheet structure, with a hinge area 41 at one end of the sheet structure and a suspension area 42 at the end of the sheet structure away from the hinge area 41. The hinge area 41 is hinged to the wall of the recessed area 1112 so that the hinge area 41 of the sheet structure hook 40 can rotate around the hinge position on the wall of the recessed area 1112.

[0087] When it is necessary to suspend the electric brush 1, the sheet structure can be rotated so that the suspension area 42 of the sheet structure rotates out of the recessed area 1112 in the direction of the first end face 1111, so as to suspend it on a hook-like object at a location such as a wall. When it is not necessary to suspend it, the sheet structure can be rotated so that the suspension area 42 rotates into the recessed area 1112 in the direction of its concavity.

[0088] This application does not limit the specific shape of the sheet structure. In some embodiments, the projection of the sheet structure in its thickness direction can be a streamlined shape such as a circle, a semicircle, an ellipse, or a semi-ellipse, or a polygonal prism such as a triangle, a quadrilateral, or a pentagon, or other irregular shapes.

[0089] For example, please refer to Figure 6 The hook 40 can be in the form of a semi-ring structure, with hinge areas 41 at both ends and a suspension area 42 in the middle. The two hinge areas are respectively hinged to the wall surface at the recessed area 1112. The hook 40 of the semi-ring structure has two semi-circular annular surfaces opposite each other along its thickness direction. When the suspension area 42 of the hook 40 is rotated into the recessed area 1112, one semi-circular annular surface faces the head 12, and the other semi-circular annular surface faces the first end face 1111. The semi-circular annular surface facing the first end face 1111 is the exposed surface.

[0090] For example, please refer to Figure 7 The hook 40 can be a quadrilateral sheet structure, with one side of the quadrilateral sheet structure serving as a hinge area, and a through hole extending along the thickness direction of the sheet structure on the other side of the sheet structure away from this side. When suspension is required, the sheet structure can be rotated to move the through hole out of the recessed area 1112.

[0091] This application does not limit the specific shape of the recessed area 1112. In some embodiments, please refer to [the relevant documentation]. Figure 4 The recessed area 1112 can be a groove structure, which has a groove sidewall extending along the length direction D1 and a groove bottom wall staggered with the length direction D1. The groove sidewall has an inner groove wall 1114 near the first end face 1111 and an outer groove wall 1113 near the circumferential outer wall 112 of the handle portion 11. The outer groove wall 1113 of the groove structure is flush with the circumferential outer wall 112 of the handle portion 11.

[0092] The outer groove wall 1113 of the groove structure is flush with the circumferential outer wall 112 of the handle portion 11, meaning that the projection of the outer groove wall 1113 of the groove structure overlaps with the projection of the circumferential outer wall of the handle portion 11 along the length direction D1.

[0093] A recessed structure is provided at the end 111 of the handle portion 11 to form a recessed area 1112. When it is not necessary to use the hook 40 to suspend the electric brush 1, the hook 40 can be accommodated in the recessed structure. Furthermore, since the outer groove wall 1113 of the recessed structure is flush with the circumferential outer wall 112 of the handle portion 11, the circumferential outer wall 112 of the handle portion 11 of the electric brush 1 can be made into a whole, and it is not easy for dirt to accumulate on the circumferential outer wall 112.

[0094] As an example, the handle portion 11 can be cylindrical. When the hook 40 has a semi-circular structure, the bottom wall of the groove structure can be set as semi-circular. The semi-circular bottom wall has a large-radius arc surface and a small-radius arc surface. The groove sidewall connected to the large-radius arc surface is the outer groove wall 1113, and the groove sidewall connected to the small-radius arc surface is the inner groove wall 1114. The outer surface of the outer groove wall is flush with the circumferential outer wall 112 of the handle portion 11, together forming a cylindrical shell surface.

[0095] Furthermore, to facilitate rotating the hanging area 42 of the hook 40 embedded in the groove structure out of the groove structure, in some embodiments, please continue to refer to... Figure 4 A U-shaped notch 1115 can be provided at the outer groove wall 1113 of the groove structure. The operator can insert his finger into the groove structure through the U-shaped notch 1115 and contact the hook 40 inside the groove structure, thereby turning the suspension area 42 of the hook 40 out of the groove structure.

[0096] In this application, the term "U-shaped notch" does not imply that the shape of the notch is exactly the same as the letter "U". A "U-shaped notch" means that the notch located on the outer groove wall 1113 can communicate with the internal cavity of the groove structure, and the end of the notch facing the first end face 1111 is not closed by the outer groove wall 1113. As an example, the projected shape of the U-shaped notch 1115 in the direction perpendicular to the thickness of the outer groove wall 1113 can be quadrilateral. As an example, the projected shape of the U-shaped notch 1115 in the direction perpendicular to the thickness of the outer groove wall 1113 can be semi-circular.

[0097] To further facilitate the operator's rotation of the hook 40 embedded within the groove structure, in some embodiments, please refer to [the relevant documentation]. Figure 5A protrusion 43 can be provided in the suspension area 42 of the hook 40 corresponding to the U-shaped notch 1115. When the hook 40 is accommodated in the groove structure in the first state, the outer end of the protrusion 43 passes through the U-shaped notch 1115 and protrudes beyond the circumferential outer wall 112. The operator can directly contact the protrusion 43 extending beyond the U-shaped notch 1115, apply force to the protrusion 43, and thus realize the rotation of the hook 40, making operation convenient.

[0098] Alternatively, in some other embodiments, the height of the outer groove wall 1113 of the groove structure is lower than the height of the inner groove wall 1114 of the groove structure.

[0099] The height of the outer groove wall 1113 of the groove structure being lower than the height of the inner groove wall 1114 means that, when projected along a direction perpendicular to the length direction D1, the projection of the outer groove wall 1113 lies between the projection of the inner groove wall 1114 and the projection of the head 12. When the hook 40 is accommodated within the groove structure in the first state, the hook 40 protrudes from the outer groove wall 1113 in a direction away from the head 12, allowing the operator to directly contact the part of the hook 40 that protrudes from the outer groove wall 1113 and thus rotate the hook 40.

[0100] Alternatively, in other embodiments, please refer to Figure 8 The recessed area 1112 can be set as an L-shaped notch. (See also...) Figure 9 When the hook 40 is in the first state, the suspension area 42 is located in the L-shaped notch, and the outer periphery of the suspension area 42 is flush with the circumferential outer wall 112 of the handle portion 11.

[0101] In this application, an "L-shaped notch" refers to a notch on one side that is not closed by the outer wall of the handle portion 11, which is equivalent to removing the outer groove wall 1113 in the groove structure. This application does not limit the shape of the notch to be exactly the same as the letter "L". Any scheme in which two intersecting surfaces are formed in the recessed area 1112 of the end 111, and at least part of the circumferential area of ​​the recessed area 1112 is not closed by the circumferential outer wall of the end 111, is within the protection scope of this application.

[0102] In this embodiment, the recessed area 1112 is set as an L-shaped notch. When the hook 40 is in the first state, the suspension area 42 is located in the L-shaped notch, and the outer periphery of the suspension area 42 is flush with the circumferential outer wall 112 of the handle portion 11. Therefore, when the operator needs to rotate the hook 40, he / she can directly contact the outer periphery of the suspension area 42 of the hook 40 and then rotate the hook 40.

[0103] This application does not limit how the hook 40 is rotatably disposed in the recessed area 1112. In some embodiments, please refer to [the relevant documentation]. Figure 6 , Figure 8 and Figure 9A hinge shaft 113 can be provided on the wall of the recessed area 1112 to hinge the hinge area 41 of the hook 40 to the hinge shaft 113.

[0104] As an example, the hook 40 can be in the form of a sheet structure, with a hinge area 41 at one end of the sheet structure, a suspension area 42 at the end of the sheet structure away from the hinge area 41, a hinge shaft 113 at the wall of the recessed area 1112, and a hinge hole at the hinge area 41 at the end of the sheet structure. The hinge hole is fitted onto the hinge shaft 113, so that the hook 40 of the sheet structure can rotate around the hinge shaft 113.

[0105] For example, the recessed area 1112 can be configured as a rectangular groove structure. The groove structure has an inner groove wall 1114, an outer groove wall 1113, and two opposing side walls connecting the inner groove wall 1114 and the outer groove wall 1113. A hinge shaft 113 extending into the internal space of the groove structure can be provided at the side wall of the groove structure, and the hinge hole of the hook 40 can be fitted onto the hinge shaft 113.

[0106] For example, the hook 40 has a semi-circular sheet structure, and each of the two ends of the hook 40 has a hinge area 41 with a hinge hole. The recessed area 1112 can be a semi-circular groove structure. A hinge shaft 113 perpendicular to the inner groove wall 1114 can be provided at each end of the groove structure. The hinge shaft 113 extends into the groove structure, and the hinge holes at both ends of the hook 40 are fitted onto the hinge shaft 113 one by one.

[0107] Alternatively, in some embodiments, the hinge pin 113 can be replaced with a hinge. One page of the hinge is fixed to the wall of the recessed area 1112, and the other page of the hinge is fixed to the hanging area 42 of the hook 40.

[0108] Furthermore, to facilitate adjustment of the rotation angle of the hook 40 relative to the hinge shaft 113, in some embodiments, a damping hinge (not shown in the figure) can be provided at the hinge shaft 113, so that the hinge area 41 of the hook 40 is connected to the hinge shaft 113 through the damping hinge. The type and arrangement of the damping hinge can be set according to conventional damping methods, and this application does not impose any restrictions.

[0109] Alternatively, in some possible embodiments, please continue to refer to Figure 6 and Figure 9Along the first extension direction of the hook 40 in the first state, the two ends of the recessed area 1112 each have end walls, and the two ends of the recessed area 1112 near the two end walls are respectively provided with hinge shafts 113. The two hinge areas 41 of the hook 40 are respectively hinged to the two hinge shafts 113, and when the hook 40 rotates, the two ends of the hook 40 can respectively contact the two end walls. Along the rotation direction of the hook 40, each end wall is provided with multiple limiting slots 1116. When the hook 40 rotates, the two ends of the hook 40 in the extension direction can be selectively restricted within one limiting slot 1116 to adjust different rotation angles of the hook 40.

[0110] As an example, the hook 40 has a semi-circular ring-shaped sheet structure. Along the arc of the semi-circular ring, the hook has two ends, each with a hinge hole. The recessed area 1112 can be a semi-circular ring-shaped groove structure. A hinge shaft 113 perpendicular to the inner groove wall 1114 can be provided at both ends of the groove structure. The hinge shaft 113 extends into the groove structure, and the hinge holes at both ends of the hook 40 are fitted onto the hinge shaft 113 in a corresponding manner. The groove structure also has two oppositely arranged end walls connecting the inner groove wall 1114 and the outer groove wall 1113. Multiple limiting slots 1116 are provided at both end walls, spaced apart along the rotation direction of the hook 40. When the hook 40 is in the first state, the end of the hook 40 is engaged in the limiting slot 1116 near the first end face 1111. When the suspension area 42 needs to be rotated a certain angle toward the first end face 1111, according to the lever principle, the end of the hook 40 will rotate away from the first end face 1111 and be locked in another limiting slot 1116. Without applying external force to the hook, the hook 40 can be kept at that angle by the cooperation between the end of the hook 40 and the limiting slot 1116.

[0111] Furthermore, for easier adjustment, please refer to [link / reference needed]. Figure 6 Alternatively, the limiting slot 1116 can be set as an arc-shaped slot, and an arc-shaped limiting block 44 can be set at the end of the hook 40.

[0112] Alternatively, in some embodiments, the recessed area 1112 can be configured as a groove structure, and the outer periphery of the hook 40 can be interference-fitted into the groove structure. After the hook 40 rotates to a certain angle, a portion of the hook 40 is always interference-fitted with the inner wall of the groove structure. At this time, without applying external force to the hook 40, the interference fit between the hook 40 and the groove structure can fix the hook 40 at that angle, thereby achieving the adjustment of the rotation angle of the hook 40.

[0113] As an example, this application provides an electric brush 1, including a housing 10, a power mechanism 20, a brush head 30, and a hook 40. The housing 10 includes a handle portion 11, a neck 13, and a head 12 connected sequentially along the length direction D1. The end portion 111 of the handle portion 11 has a recessed area 1112 with a groove structure located near the circumferential outer wall 112 of the end portion 111. The inner groove wall 1114 of the groove structure is connected to the first end face 1111 of the end portion 111, and the outer groove wall 1113 is flush with the circumferential outer wall 112 of the handle portion 11. A U-shaped notch 1115 is provided on the side of the outer groove wall 1113 facing the first end face 1111. The groove structure is semi-circular in shape. A hook 40 is also provided at the end portion 111. The hook 40 has a semi-circular structure, with a hinge area 41 at each end along the arc direction of the hook 40, and a suspension area 42 between the two hinge areas 41. The hook 40 has a protrusion 43 in its suspension area 42. The hook 40 has a first state of contact with the handle portion 11 and a second state of separation from the handle portion 11. When the hook 40 is in the first state, it is accommodated within the recessed structure, and the exposed surface of the hook 40 facing the first end face 1111 is flush with the first end face 1111. The protrusion 43 is located within the U-shaped notch 1115, and the outer end of the protrusion 43 protrudes from the circumferential outer wall 112. When the hook 40 is in the first state, the electric brush 1 can be placed on the table with its head 12 facing upwards. When it is necessary to suspend the electric brush 1, the hook 40 can be rotated so that the suspension area 42 of the hook 40 rotates out of the recessed structure, entering the second state, thus suspending the electric brush 1 using the suspension area 42 of the hook 40.

[0114] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
