Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of brush, in particular to an electric brush and an assembly thereof. BACKGROUND

[0002] Historically, men have used shaving brushes to prepare the hair and skin prior to wet shaving. The user can apply soap or gel to the face, into a shaving cup / bowl, or onto a wet palm to create lather. The user then applies the lather to the skin with the brush, typically using a quick, short stroke, which agitates the hair on the skin and improves skin condition by exfoliating. The benefits experienced by the user during and after shaving are typically dependent on the quality of the bristles of the brush and the manner in which the lather is applied to the face. The application of the lather is dependent on the motion of the user's hand, and if not applied correctly, can limit the benefits of using the brush.

These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as "first", "second", and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, an element, component, region, layer or section discussed below can be termed a second element, component, region, layer or section without departing from the teachings of example embodiments.

[0039] For ease of description, spatial relative terms can be used herein to describe the relationship of one element or feature to another element or feature as shown in the figures, such as "inner", "outer", "inward", "outward", "lower", "below", "upper", "above", "front", "back", etc. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, then an element described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. For ease of description, the spatial orientation of the following embodiments is: the brush head is "up", the handle portion is "down", the direction of the central axis L of the power brush is longitudinal, and the direction of rotation is centered around the central axis L, i.e. the central axis L is the rotation center axis.

[0040] Referring to Figures 1-11 The present application relates to a power brush 1000, which includes a handle portion 100 and a brush head 200 mounted on the top end of the handle portion.

[0041] In the preferred embodiment, the brush head 200 is detachably and replaceably mounted on the handle portion. For different bristle areas, different brush heads should be used on the basis of hygiene considerations, on the one hand, and for different areas of hair or skin, different brush heads of different textures or sizes are used to obtain comfort, and different brush heads 200 can be replaced. Different brush heads 200 can have different diameters, lengths, hardnesses, etc. of bristles; for example, brush head one has a diameter of 20 mm and a bristle length of 55 mm; brush head two has a diameter of 18 mm and a bristle length of 52 mm; and bristles of different hardnesses and textures can also be used.

[0042] The electric brush 1000 of the present application, the brush head 200 can be set to rotate at different speed gears, cooperating with the foaming bowl 300 (refer to Figures 9-11 ), the following working modes can be executed:

[0043] 1) Foaming working mode: mixing and foaming the shaving (hair) soap / shaving (hair) cream / shaving (hair) gel, which can foam faster, and the high-speed rotating bristles can produce more dense and abundant foam;

[0044] 2) Foam application working mode: using the bristles of the electric brush to apply the foam in the foaming bowl to the skin or hair;

[0045] 3) Cleaning bristles working mode: when cleaning the electric brush, start the motor and use the high-speed rotating gear, which can clean the residual foam in the bristles more quickly and efficiently;

[0046] 4) Spin-drying bristles working mode: after cleaning the brush head, the residual water in the bristles can be quickly spun dry.

[0047] In a specific embodiment, the brush head 200 is detachably and rotatably connected to the top end of the handle part. The brush head 200 is connected to the top of the hand cup part by magnetic attraction. The brush head 200 includes bristles 20, a bristle cup 21, and a first magnet 22. The bristles 20 and the first magnet 22 are installed in the bristle cup 21, which can be fixedly installed in the bristle cup 21 or rotatably fixed along the central axis L or longitudinally extractable in the bristle cup 21. When the brush head 200 rotates relative to the handle part, the bristles 20, the bristle cup 21, and the first magnet 22 rotate together.

[0048] The bristles 20 are a bundle of bristles attached to the base 201, which can be formed by bonding the roots of the bristles together, and / or the bristle base 201 is an independently arranged annular component, and the roots of the bristles are bonded and fixed in the base 201.

[0049] The bristle cup 21 is cylindrical, such as but not limited to a circular cylinder, including an annular side wall 215 and a bottom wall 210. The top of the bristle cup 21 forms a bristle assembly cavity 2 for mounting the bristles 20, which is used to adaptably mount the bristle base 201. The upper surface of the bottom wall 210 of the bristle assembly cavity 2 is a bristle assembly surface; the bristle assembly cavity 2 is adapted to the bristle base 201 of the bristles 20, which is fixed in the bristle assembly cavity 2 of the bristle cup 21, or the bristle base is relatively fixed (does not rotate relatively) in the bristle assembly cavity 2 in the rotation direction but can be extracted and replaced along the longitudinal direction or the central axis L. The bristle base and the assembly surface of the bottom wall 210 of the bristle cup are in close contact with each other. Non-limiting examples, the base 201 and the bristle cup 21 can be made of magnetic materials such as iron, but are not limited to magnetic materials.

[0050] Refer to Figures 1-7In the first embodiment, the lower surface of the bottom wall 210 of the bristle cup 21 (opposite to the assembly surface) forms a recessed mounting groove 214, which is shaped to match the first magnet 22 for mounting the first magnet 22. It is understood that the mounting groove 214 can be a recess in the bottom wall 210 or a through hole in the bottom wall. For example, the first magnet 22 is square in shape and the mounting groove 214 is a square groove, the first magnet 22 is fixed in the mounting groove 214 or is rotatably fixed in the mounting groove 214 but can be pulled out along the longitudinal direction or the central axis L. The first magnet 22 has a through hole 220 in the center, and when the brush head 200 is connected to the top of the handle portion 100, the output shaft 130 of the output gear 13 is inserted into the through hole 220 and is fixed in the rotating direction. The shape of the central through hole 220 can be polygonal, and no relative rotation occurs between the output shaft. For example, the first magnet 22 can be magnetically attracted to the bristle cup and / or the bristle base. When the brush head 200 is removed, the entire brush head 200 can be pulled out from the top of the handle portion, and then the brush head 200 can be replaced as needed, or the bristles 20 can be further replaced. Preferably, the first magnet 22 is a permanent magnet.

[0051] The top of the handle portion 100 forms a brush head assembly cavity 160, which matches the bottom of the brush head 200, and the bristle cup 21 is accommodated in the brush head assembly cavity 160 and is rotatably fixed. The brush head 200 can be pulled out from the brush head assembly cavity 160 along the longitudinal direction or along the central axis L. The upper surface of the bottom wall of the brush head assembly cavity 160 (i.e., the brush head assembly surface) is provided with a second magnet 22', which protrudes upward from the brush head assembly surface and is mounted at the end of the output shaft 130 of the output gear 13. When the brush head 200 is connected to the handle portion 100, the brush cup 21 is embedded in the brush head assembly cavity 160 of the handle portion, and the second magnet 22' protruding upward from the bottom wall of the brush head assembly cavity 160 is inserted into the mounting groove 214 of the bottom wall of the brush cup and is fixed in the rotating direction without relative rotation; the two magnets 22, 22' are magnetically attracted to each other, stacked one above the other, and coaxially connected to the end of the output shaft 130. As an example, the second magnet 22' is the same as the first magnet 22 (or can be different), and the central through holes 220 of the two magnets 22, 22' can be square through holes that are non-circular, and are rotatably connected by the same output shaft 130.

[0052] The handle part 100 comprises a shell 17, which is internally a cavity; the cavity is internally provided with a support 18, and a motor 15, a gear set, a control circuit board 14, a battery 19 and the like mounted by the support. The gear set comprises a motor gear 10, an intermediate gear and an output gear 13, which are in meshing transmission with each other. The motor drives the motor gear 10 to rotate, which drives the intermediate gear to rotate through meshing transmission, and drives the output gear 13 to rotate through meshing transmission between the intermediate gear and the output gear 13, and the rotation at multiple speeds is realized by the control of the control circuit board 14 (high-speed foaming gear / high-speed cleaning gear / fast spin-drying gear), and the specific rotation speed can be adjusted according to actual conditions. The intermediate gear can comprise one or more intermediate gears or no intermediate gear. The central shaft of the motor gear 10 is the motor output shaft, which is arranged at the top of the motor output shaft. For example, the intermediate gear comprises two coaxial intermediate gears 11, 12 arranged in an upper-lower manner, which rotate synchronously, the lower first intermediate gear 11 is in meshing transmission with the motor gear, and the upper second intermediate gear 12 is in meshing transmission with the output gear 13. In other embodiments, one intermediate gear is adopted, which is in meshing transmission with the motor gear 10 and the output gear 13 respectively; or a plurality of intermediate gears can be adopted, which are coaxially connected or have parallel central shafts and are in meshing transmission. The multiple-stage gear arrangement can obtain multiple gears for speed regulation. The output gear 13 is tightly fitted with the output shaft (central shaft) 130 arranged in the central through hole thereof, and an O-shaped fastening ring and an O-shaped gasket can be further arranged to tightly fit the output shaft 130 with the output gear 13. The second magnet 22' is arranged at the end of the output shaft 130, and the end of the output shaft 130 is fixedly connected by being inserted into the central through hole 220 of the second magnet 22'. An external thread or a structure feature for increasing friction can be arranged at the end of the output shaft 130, and a rubber piece 23 can be sleeved at the end of the output shaft 130 before being inserted into the central through hole of the second magnet 22', the rubber piece 23 is in the shape of a cap, and an internal thread or a structure feature for increasing friction can be arranged in the cap to increase the friction between the end of the output shaft 130 and the mating surface or form a threaded fit, and the rubber piece 23 is matched with the central through hole of the second magnet 22', for example, in the shape of a square. The end of the output shaft of the output gear 13 is inserted into the central through hole of the second magnet 22', and can be further inserted into the central through hole of the first magnet 22, so that the two magnets are connected in series and are attracted to each other. The motor drives the motor gear 10 to rotate, and the intermediate gear is in meshing transmission to drive the output gear 13 to rotate, and the output shaft 130 is driven to rotate to drive the brush head 200 to rotate. The central shaft (or input shaft or output shaft) 130 of the motor gear 10, the intermediate gears 11, 12 and the output gear 13 is parallel or collinear with the central axis L of the electric brush 1000.

[0053] The shell 17 is in the shape of a cylinder as a whole, which can be designed to be suitable for holding in hand, for example, in the shape of a cylindrical side wall with a curved surface, which is convenient for holding and resting on the curved surface 330 of the frothing bowl support. The top of the shell 17 is open, and the bottom is provided with a bottom wall to support the various components installed inside.

[0058] The electric brush 1000 of the present application, the brush head 200 is rotatably mounted in the cavity 160 at the top of the handle, and is detachably connected by the central axis direction or longitudinal magnetic attraction. The first magnet 22 is arranged in the brush head 200, and the second magnet 22' is arranged in the cavity 160 at the top of the handle. The base of the brush head and the bristle cup 21 are made of magnetic material to obtain magnetic attraction between the magnets 22 and 22'. The magnet 22, 22' is arranged in the installation groove of the bristle cup 21 at the bottom of the brush head 200. The first magnet 22 can be clamped in the installation groove (specifically, the rotational direction is not relatively active, and the longitudinal or depth direction is movable). When the brush head 200 is connected to the top of the handle 100, the second magnet 22' is also clamped in the installation groove in the bristle cup 21 (specifically, the rotational direction is not relatively active, and the longitudinal direction is movable). The first magnet 22 and the second magnet 22' are provided with through holes 220 at the center. The output shaft 130 of the output gear 13 in the handle 100 passes through the central through holes 220 of the first magnet 22 and the second magnet 22'. The handle 100 and the brush head are magnetically attracted and connected in the rotational direction. The output shaft 130 drives the brush head 200 to rotate synchronously. The motor 15 in the handle 100 drives the gear 10 connected to the motor output shaft to rotate. The intermediate gears 11 and 12 are engaged to drive the output gear 13 to rotate. The intermediate gears can be engaged with each other, or the intermediate gears can not be provided, and the motor gear 10 is directly engaged with the output gear 13 to drive the output gear 13 to rotate.

[0059] The motor 15 of the electric brush 1000 cooperates with the gear set, which is controlled by the control circuit board 14 to realize high-speed rotation of the brush head. It is mainly used for foaming of shaving cream (or shaving soap or shaving gel) and applying shaving cream on the face during shaving. The rotation speed of the bristles is realized by the motor gear 10 cooperating with the gear set. According to the needs, multiple gears with different rotation speeds can be set, such as foaming gear, cleaning gear and spin-drying gear, etc. Other gears can also be set for users to choose according to different adaptability. When the electric brush 1000 is applied to shaving cream foaming and stirring, the high-speed rotating bristles can produce more dense and abundant foam. When the bristles are cleaned with water or cleaning agent after shaving, the high-speed rotation gear can be set to clean the remaining foam in the bristles more quickly and efficiently. After cleaning, the fast gear can be set to spin-dry the residual moisture in the bristles.

[0060] Reference Figures 8-11The second embodiment of the electric brush 1000 differs from the first embodiment of the electric brush 1000 mainly in the arrangement of the first magnet 22 and the second magnet 22'. Specifically, the top of the bristle cup 21 forms a bristle assembly cavity 2, the bottom wall of which, i.e. the bristle assembly face 210, is concave in the center to form a mounting groove 211, and the mounting groove 211 is provided with a protruding column 212 extending upward in the center, and the shape of the mounting groove 211 is adapted to the first magnet 22. The first magnet 22 is mounted in the mounting groove 211 from the bristle assembly face, and preferably the top surface of the mounting groove 211 and the first magnet 22 is flat, and the first magnet 22 does not protrude upward from the bristle assembly face, so as to be close to the end face of the bristle base. The protruding column 212 is inserted into the central through hole 220 of the first magnet 22 and is fixedly connected in the rotation direction. For example, the overall shape of the first magnet 22 is square, and the mounting groove is a square groove, and the first magnet 22 can be fixed in the mounting groove 211, or the first magnet 22 is fixed in the mounting groove in the rotation direction but can be pulled out in the longitudinal direction or the central axis L direction. For example, the bottom end of the protruding column 212 forms a hole, the bristle cup 21 includes two cup bodies that are sleeved with each other, and the protruding column 212' at the bottom wall of the outer cup body is inserted into the hole at the bottom end of the protruding column 212 of the inner cup body and is inserted with each other. The bottom end of the protruding column 212' at the bottom wall of the outer cup body can form a hole for inserting the output shaft 130 of the output gear 13. The lower surface of the bottom wall 210 of the bristle cup 21 (opposite to the assembly face) forms a concave mounting groove 214, and the bottom surface of the bottom wall of the mounting groove 214 is provided with a hole (or a hole formed at the bottom end of the protruding column 212') 213 in the center. The shape of the mounting groove 214 is adapted to the magnet housing 24 to mount the magnet housing 24, so that the magnet housing 24 does not rotate relatively in the mounting groove 214, but can be pulled out in the longitudinal direction (central axis L direction).

[0061] The second magnet 22' is arranged on the bottom wall 161 of the brush head assembly cavity 160 at the top of the handle part 100, and is installed at the end of the output shaft 130 of the output gear 13. The second magnet 22' is annular, with a through hole in the center, and is the same as the first magnet 22 (or can be different). For example, the second magnet 22' and the first magnet 22 are square, with a square through hole 220 in the center. A magnet housing 24 is arranged outside the second magnet 22' to reinforce the second magnet 22' and prevent the magnet from leaking. The magnet housing 24 is shaped to fit the second magnet 22', and is tightly fitted outside the second magnet 22'. The magnet housing 24 is provided with an annular clamping groove 242, a protruding column 241, and a central through hole 240 that is an axial through hole. The annular clamping groove 242 and the protruding column 241 are adapted to the second magnet 22', the second magnet 22' is embedded in the annular clamping groove 242, the protruding column 242 is inserted into the central through hole 220 of the second magnet 22' and the central through hole 240 of the magnet housing 24, and can continue to extend upward and be inserted into the central hole of the lower surface of the bottom wall of the bristle cup. When the second magnet 22' tightly fitted outside the magnet housing 24 is embedded in the mounting groove 242 of the bottom wall of the bristle cup, the rotation direction is fixed, and the central axis L direction can be separated (pulled out). The first magnet 22 and the second magnet 22' are permanent magnets, for example.

[0062] When the brush head 200 is connected to the handle part 100, the brush cup 21 is inserted into the brush head assembly cavity 160 at the top of the handle part, and the second magnet 22' protruding upward from the bottom wall of the brush head assembly cavity 160 and the magnet housing 24 arranged outside it are inserted into the mounting groove 214 of the lower surface of the bottom wall of the bristle cup and are fixed in the rotation direction to rotate synchronously without relative rotation; the two magnets 22, 22' are attracted to each other by magnetic force. The end of the output shaft 130 of the output gear 13 is inserted into the central through hole 220 of the second magnet 22' and the central through hole 240 of the magnet housing 24, and can be further inserted into the hole formed by the bottom wall of the bristle cup 21 (or the bottom end of the protruding column 212'), and the brush head 200 is rotated by the output shaft 130. The motor gear 10 is driven to rotate by the motor, and the output gear 13 is driven to rotate by the intermediate gear, and the output shaft 130 is driven to rotate, thereby driving the brush head 200 to rotate.

[0063] The other structures of the second embodiment are the same as or similar to those of the first embodiment, and can be directly referenced in the second embodiment.

[0064] Reference Figures 12-15The electric brush 1000 of the present application is configured with a lathering bowl 300 for lathering, washing / drying / air-drying the shaving cream. In some embodiments, the electric brush 1000 can also be attached to the rotating support 30 of the lathering bowl 300 by magnetic attraction. The lathering bowl 300 is provided with a rotating support 30 at the rim of the bowl opening, which can be rotated and adjusted to different angles to support the electric brush 1000 at different angles. The rotating support includes a bearing seat 31, a rotating base 32, an upper cover 33, and a rotating shaft 34. The bearing seat 31 is fixed to the outer wall of the rim of the bowl opening and can be a set of parallel plates (in the form of a comb) arranged at intervals, each plate being provided with a shaft hole, and the shaft holes being connected in correspondence. The rotating base 32 includes a rotating arm 321 and a bottom cover 320 connected at the upper end, and the rotating arm 321 is adapted to the bearing seat 31, for example, a set of L-shaped (not limited to L-shaped) parallel plates (in the form of a comb), and the bottom end is provided with a shaft hole in correspondence, and the shaft holes are connected in correspondence. The parallel plates of the rotating arm 321 and the parallel plates of the bearing seat 31 are inserted between each other, wherein one plate of the rotating arm 321 is inserted into the interval between every two parallel plates of the bearing seat 31, the shaft hole of the rotating arm and the shaft hole of the bearing seat are connected in correspondence, located in the same direct, and inserted into the rotating shaft 34. The upper cover 33 and the bottom cover 320 are adapted in shape and are tightly connected by buckling, and an inner cavity is formed, which can be provided with a fourth magnet, and a magnetic force is formed between the fourth magnet and the third magnet 187 in the handle portion. The upper surface of the upper cover 33 is adapted in shape to the handle portion of the electric brush 1000, and in a specific example, the upper surface 330 of the upper cover 33 is a curved surface, and the outer shell of the handle portion has a corresponding curved surface, for example, the surface of the outer shell at the position where the third magnet 187 is installed is a curved surface, and the two curved surfaces are adapted in shape and area, so that the contacted outer shell surface is attached to the upper surface 330 of the upper cover 33, and the electric brush 1000 and the lathering bowl 300 are magnetically attracted to each other. The rotating arm 321 of the rotating base 32 and the bearing seat 31 are rotatably connected by the rotating shaft 34, and can be stably supported at several angular positions, for example, the electric brush is horizontally supported on the bowl opening of the lathering bowl when rotated to the horizontal position (refer to Figure 13 ), which is used for air-drying the brush hairs; or the electric brush is supported on the support by magnetic attraction when rotated to the vertical position (refer to Figure 12 ), and the brush head is located at the bottom of the lathering bowl. The upper cover 33 and / or the entire rotating support 30 can be made of a magnetic material. The rotating shaft 34 can be a screw rod 34, one end of which is a nut to tightly clamp the edge of one outer shaft hole, and the other end is provided with a through hole, and a screw 35 is inserted into the through hole of the screw rod from the other outer shaft hole to fixedly connect.

[0065] When the electric brush 1000 is used to lather the shaving soap in the lathering bowl 300, the electric brush 1000 can be held in hand, and the speed is set to the high-speed lathering speed. The shaving soap / shaving cream / shaving gel can be automatically lathered faster than the traditional electric brush. The high-speed rotating bristles can produce more dense and abundant foam. When the foam is applied, the bristles are used to apply the foam in the lathering bowl to the skin or hair on the face or corresponding area. The motor is also started to move at an appropriate speed while applying. After shaving, the cleaning agent or water can be placed in the lathering bowl 300. The electric brush 1000 is held in hand, and the speed is set to the high-speed cleaning speed. The high-speed rotating gear is used to clean the residual foam in the bristles more quickly and efficiently. After cleaning, it can be adjusted again to the high-speed spin-drying speed to quickly spin-dry the residual moisture in the bristles. After spinning the bristles, the electric brush 1000 is placed horizontally by rotating the support 30.
