Description
Technical Field
[0001] This utility model relates to the field of electric cleaning brush technology, and in particular to an electric cleaning brush that uses a bristle brush for cleaning. Background Technology
[0002] In existing literature, Chinese utility model publication CN2927822Y discloses a grill brush. This device includes a handle and a brush head with a fixed rigid metal wire, as well as a housing, a drive mechanism located within the housing, a power supply, and a control switch. The brush head is driven by a rotating shaft connected to the drive mechanism, and the drive mechanism, power supply, and control switch form a drive circuit. The drive mechanism includes a motor and a gear set, which is enclosed in a plastic housing. One end of the gear set is connected to the output shaft of the motor, and the other end has a rotating shaft. The brush head rotates rapidly under the action of the drive mechanism, brushing away residue from the grill with the metal wire on the brush head. Using electric power instead of manual brushing makes brushing easier and faster. However, it has the following problems:
[0003] 1. The metal wires are inserted into the central shaft of the brush head using a bristle-like method. After a period of use, the metal wires tend to loosen and fall off, which needs to be improved.
[0004] 2. The surface of the metal wire is relatively smooth. When the metal wire passes through the mesh of the grill and comes into contact with the sides of the wire on both sides of the mesh, the friction is small, which is not conducive to cleaning the wire on both sides of the mesh.

[0016] A further technical solution of this utility model: a connecting part mounting groove is formed on the outer peripheral surface of the connector, and the connecting part mounting groove has an outlet corresponding to the outer peripheral surface of the connector;
[0017] The mounting groove of the connecting part extends toward the end of the connector and passes through the end face of the end of the connector to form a mounting opening for the connecting part;
[0018] The protrusion has a constricted section around its perimeter. The constricted section is designed so that the width of the protrusion is smaller than the width of the mounting groove of the connecting part.
[0019] The bristle connector is inserted into the connector mounting slot from the connector mounting port, and the bristles clamped on the bristle connector extend out of the outer periphery of the connector through the protrusion.
[0020] The constricted opening restricts the bristle connection, preventing it from coming out of the protrusion.
[0021] A further technical solution of this utility model: a plurality of connecting part mounting grooves are provided at circumferential intervals along the outer peripheral surface of the connector, and corresponding bristle connecting parts are provided in the connecting part mounting grooves.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0054] Please see Figure 1-11 An electric cleaning brush includes a brush head 1, a rotary drive assembly 2, and a brush body 3 having a handheld part 4.
[0055] The handheld part 4 is adapted to be held by the user, so as to facilitate manual operation of the electric cleaning brush. The handheld part 4 is provided, for example, at the rear end of the brush body 3.
[0056] The brush head 1 is rotatably mounted on the brush body 3, for example, the brush head 1 is rotatably mounted at the front end of the brush body 3.
[0057] The rotary drive assembly 2 is used to drive the brush head to rotate, so that when the user operates this electric cleaning brush, the brush head 1 driven by the rotary drive assembly 2 can be placed against a mesh-like item such as a barbecue grill, and the rotating brush head 1 can clean the mesh-like item.
[0058] The brush head 1 and the handheld part 4 are respectively located at the front and rear ends of the brush body 3, and a certain distance is formed accordingly, which can effectively prevent the brush head from scratching the hand when cleaning by rotating.
[0059] In some embodiments, the brush head 1 includes a shaft-shaped connector 11 and a contact cleaning element 12 disposed outside the connector. The rotary drive assembly 2 drives the connector 11 to rotate, and the contact cleaning element 12 rotates accordingly with the connector 11 or is driven to rotate by the connector 11. When operating this electric cleaning brush, the user can place the rotating contact cleaning element 12 against a mesh-like item such as a barbecue grill, thereby continuously rotating and rubbing the mesh-like item to clean it, thus forming a rotating brushing action.
[0060] In some embodiments, the length direction of the rotation center line of the connector 11 during rotation coincides with the axis of the connector 11.
[0061] like Figure 1-11 As shown, in some embodiments, the contact cleaning element 12 includes multiple bristles 122 disposed on the connector 11. The bristles 122 may be made of metal, for example, to have good hardness and wear resistance. For example, the bristles 122 may be made of steel wire structure.
[0062] In some embodiments, a bristle connecting portion 123 is provided on the outer side of the connector 11, and a portion of the bristles 122 can be correspondingly connected to the bristle connecting portion 123. When the connector 11 rotates, the bristles 122 can be driven to rotate to clean the mesh-like items.
[0063] In some embodiments, the bristles 122 have a curved cleaning portion 1221, which can correspondingly increase the cleaning range during rotation; and during cleaning, by bending the bristles (the portion with the curved cleaning portion) that pass through the mesh can increase the friction when cleaning the mesh-like item, making it easier to clean.
[0064] In some embodiments, the curved cleaning portion 1221 has a proximal end close to the outside of the connector and a distal end away from the outside of the connector; between the proximal end and the distal end of the curved cleaning portion 1221, the curved cleaning portion 1221 has multiple curved segments.
[0065] In some embodiments, the bristle connector 123 is configured to clamp and connect the bristles 122 in a clamping manner.
[0066] In some embodiments, the bristle connecting portion 123 includes a clamping main body portion 1233 and a first clamping wing 1231 and a second clamping wing 1232 connected to the clamping main body portion. The first clamping wing 1231 and the second clamping wing 1232 are disposed opposite to each other and are configured to clamp each other to clamp the bristles 122 located between the first clamping wing and the second clamping wing.
[0067] In some embodiments, the clamping body 1233, the first clamping wing 1231, and the second clamping wing 1232 may be made of metal to provide better clamping and holding capabilities. For example, the first clamping wing 1231 and the second clamping wing 1232 may be made of sheet metal.
[0068] In some embodiments, the first clamping wing 1231 and the second clamping wing 1232 both have a certain width and length. Therefore, when the first clamping wing 1231 and the second clamping wing 1232 are brought close together, they can clamp multiple bristles simultaneously.
[0069] When clamping, a portion of the bristles 122 are clamped between the first clamping wing 1231 and the second clamping wing 1232, while another portion of the bristles 122 protrudes from between the first clamping wing 1231 and the second clamping wing 1232 and is located outside the bristle connection portion 123 for cleaning items.
[0070] In some embodiments, the first clamping wing 1231 and the second clamping wing 1232 each have a proximal end connected to the clamping body portion 1233 and a distal end away from the clamping body portion 1233. The distal ends of the first clamping wing 1231 and the distal ends of the second clamping wing 1232 correspond to each other.
[0071] The first clamping wing 1231 has a first clamp 1234 extending to the far end of the second clamping wing 1232, and the second clamping wing 1232 has a second clamp 1235 extending to the far end of the first clamping wing 1231. When the first clamping wing 1231 and the second clamping wing 1232 are clamped together, the first clamp 1234 and the second clamp 1235 together clamp the bristles 122.
[0072] In some embodiments, the bristle connecting portion 123 has a length direction extending towards both ends of the connector 11. After the first clamp 1234 and the second clamp 1235 are clamped together, an internal space of the bristle connecting portion is obtained, which is jointly enclosed by the clamping main body 1233, the first clamping wing 1231 and the second clamping wing 1232. The length direction of this internal space corresponds to the length direction of the bristle connecting portion 123. The length setting allows the bristle connecting portion 123 to clamp more bristles at the same time.
[0073] In some embodiments, a fixing post 1236 is provided in the internal space of the bristle connecting part 123, and the length direction of the fixing post 1236 corresponds to the length direction of the internal space of the bristle connecting part 123.
[0074] One end of the bristle 122 is inserted into the internal space of the bristle connector 123 and passes through the internal space of the bristle connector 123 after passing around the fixing post 1236; that is, the bristle has a winding section that passes around the fixing post, and two bristle ends connected to the winding section and located outside the internal space of the bristle connector 123, at least one bristle end having a curved cleaning section.
[0075] The arrangement of the fixing post 1236 and the bristles 122 makes it less likely for the bristles 122 to fall off after they are clamped.
[0076] In some embodiments, the width of the fixing post is greater than the distance between the first clamp and the second clamp after the brush bristles are clamped.
[0077] In some embodiments, a connecting portion mounting groove 111 is formed on the outer peripheral surface of the connector 11. The connecting portion mounting groove 111 has an extension corresponding to the outer peripheral surface of the connector 11. The connecting portion mounting groove 111 extends toward the end of the connector 11 and penetrates the end face of the end of the connector 11 to form a connecting portion mounting opening. A constriction portion 112 is provided around the periphery of the extension. The constriction portion 112 is integrally formed on the connector, for example, and the width of the extension is smaller than the width inside the connecting portion mounting groove 111.
[0078] The bristle connecting part 123 is inserted into the connecting part mounting groove 111 from the connecting part mounting port, and the bristles 122 connected to the bristle connecting part 123 extend out of the outer peripheral surface of the connector 11 through the protrusion.
[0079] The constricted portion 112 restricts the bristle connector 123 to prevent the bristle connector 123 from coming out of the protrusion.
[0080] In some embodiments, the inner wall of the connecting part mounting groove 111 also provides support for the first clamping wing 1231 and the second clamping wing 1232. That is, after the bristle connecting part 123 is inserted into the connecting part mounting groove 111, during rotational cleaning, the inner wall of the connecting part mounting groove 111 can support the first clamping wing 1231 and the second clamping wing 1232 to limit the clamping opening of the first clamping wing 1231 and the second clamping wing 1232 from becoming excessively large. Thus, during high-speed rotational cleaning, the bristles 122 subjected to cleaning friction can still be well held on the bristle connecting part 123.
[0081] In some embodiments, the length direction of the connecting part mounting groove 111 is the same as the axial direction of the connecting member 11.
[0082] In some embodiments, a plurality of connection mounting grooves 111 are provided at circumferential intervals on the outer peripheral surface of the connector 11, and corresponding bristle connecting parts 123 are provided in the connection mounting grooves 111.
[0083] The insertion of the bristle connector 123 allows each bristle (in the corresponding bristle connector) to be individually removed from the brush head, which facilitates thorough cleaning of the brush head 1 and enables individual replacement of each bristle.
[0084] In some embodiments, the brush body 3 includes a base 31 and a first connecting arm 32 and a second connecting arm 33 disposed on both sides of the base 31. The base 31 and the first connecting arm 32 and the second connecting arm 33 together form a mounting position for mounting a brush head. Figure 1 , 3 As shown, the first connecting arm 32 and the second connecting arm 33 are located on both sides of the base 31 corresponding to the axial direction of the connector 11.
[0085] In some embodiments, the first connecting arm 32 and the base have a communicating inner cavity, and the rotation drive assembly 2 includes a drive motor 21 disposed in the inner cavity, the drive motor 21 being used to drive the brush head 1 to rotate.
[0086] In some embodiments, the rotary drive assembly 2 further includes a transmission assembly 22 disposed in the inner cavity, through which the rotation output by the drive motor 21 is transmitted to the brush head 1, thereby driving the brush head 1 to rotate.
[0087] In some embodiments, the transmission assembly 22 includes a gear set for accelerating or decelerating the rotation of the drive motor 21 and transmitting it to the brush head 1. Accordingly, the gear set for acceleration may also be called an acceleration gear set. Correspondingly, the gear set for deceleration may also be called a deceleration gear set.
[0088] In some embodiments, the gear set can be a reduction gear set, which is used to reduce the high-speed rotation of the drive motor 21 by the gear ratio of different gears in the reduction gear set, such as reducing the rotation output of 18,000 revolutions per minute to about 700 revolutions per minute. The reduction gear set increases the output torque, so that the brush head 1 can obtain greater torque and thus more effectively brush away the sticky solids in the mesh, such as the charred food on the barbecue grill.
[0089] In some embodiments, the connector 11 is connected to an output shaft 113, and the drive motor 21 directly drives the output shaft or drives the output shaft 113 through the transmission component 22 described above, thereby driving the brush head 1 to rotate.
[0090] In some embodiments, the two ends of the output shaft 113 can be supported by the first connecting arm 32 and the second connecting arm 33 respectively, or it can be understood that the two ends of the output shaft 113 are rotatably engaged with the first connecting arm 32 and the second connecting arm 33 respectively, and have good rotational stability when rotating for cleaning.
[0091] In some embodiments, the transmission assembly 22 includes a connecting shaft 221 rotatably disposed in the inner cavity of the first connecting arm 32. The axial direction of the connecting shaft 221 is the same as the axial direction of the output shaft 113. One end of the connecting shaft 221 is engaged with one end of the output shaft 113, thereby aligning the axis of the connecting shaft 221 with the axis of the output shaft 113.
[0092] In some embodiments, when the transmission assembly 22 includes a gear set, the connecting shaft 221 may be a shaft on the last stage gear of the gear set.
[0093] In some embodiments, the connection method between one end of the connecting shaft 221 and one end of the output shaft 113 may be plug-in.
[0094] For example, an axial slot 222 is formed on the end face of one end of the connecting shaft 221. The radial cross-sectional shape of the axial slot 222 is non-circular. A insertion hole 321 communicating with the inner cavity is opened on the side of the first connecting arm 32 facing the mounting position. The axial slot 222 is exposed through the insertion hole 321. For example, the connecting shaft is located inside the first connecting arm, and the opening of the axial slot faces the insertion hole, so that the axial slot located inside the first connecting arm can be contacted through the insertion hole; or, for example, one end of the connecting shaft is in the insertion hole, and the axial slot on one end of the connecting shaft is directly opposite the external opening of the insertion hole; or, for example, one end of the connecting shaft extends out from the insertion hole, so that the opening of the axial slot is located outside the first connecting arm.
[0095] One end of the output shaft 113 corresponds to the axial slot 222, and one end of the output shaft 113 can be inserted into the axial slot 222.
[0096] The radial cross-sectional shape of one end of the output shaft 113 is also a corresponding non-circular shape, which allows the output shaft 113 to be quickly engaged with the connecting shaft 221 by plugging in, and to be driven to rotate by the connecting shaft 221.
[0097] In some embodiments, the first connecting arm 32 has a mounting port 322 communicating with the inner cavity on the side facing away from the mounting position, and a sealing cover 323 covering the mounting port is detachably connected to the first connecting arm 32. During installation or maintenance, the sealing cover 323 can be removed to facilitate the aforementioned operations on the inside of the first connecting arm 32.
[0098] In some embodiments, the sealing cover 323 may be closed to the mounting port 322 in the same direction as the axial direction of the connecting shaft 221. Thus, the sealing cover 323 can also provide further support for the rotating components within the first connecting arm 32. For example, one end of the connecting shaft 221 may be supported by the first connecting arm 32, and the other end of the connecting shaft 221 may be supported by the sealing cover 323 closed to the first connecting arm, allowing for easier inspection and maintenance of the internal rotating components after the sealing cover 323 is removed.
[0099] In some embodiments, when the transmission assembly 22 includes a gear set, the sealing cap 323 can also be used to provide further support for the shaft of the gear.
[0100] In some embodiments, the sealing cap 323 and the first connecting arm 32 serve as components supporting the connecting shaft 221. The sealing cap 323 is provided with a second rigid stabilizing ring 325 that cooperates with the connecting shaft 221, and the first connecting arm 32 is provided with a first rigid stabilizing ring 324 that cooperates with the connecting shaft 221. One end of the connecting shaft 221 is correspondingly inserted into the first rigid stabilizing ring 324 and rotatably cooperates with the first rigid stabilizing ring 324. When the sealing cap 323 is closed onto the first connecting arm 32, the second rigid stabilizing ring 325 is correspondingly sleeved on the other end of the connecting shaft 221 and rotatably cooperates with the connecting shaft 221.
[0101] The first hard stabilizing ring 324 and the second hard stabilizing ring 325 are, for example, metal rings and have a certain stable length in the axial direction. After the connecting shaft 221 is engaged with the output rotating shaft 113, the first hard stabilizing ring 324 and the second hard stabilizing ring 325 can provide hard support for the connecting shaft 221.
[0102] In some embodiments, a mounting bracket 311 is provided in the base 31, and the mounting bracket 311 has a cylindrical motor mounting base 312.
[0103] The mounting bracket 311 and the motor mounting base 312 are separated in the communication space between the first connecting arm 32 and the base 31, and the first connecting arm 32 is connected to the interior of the base 31 through the cylindrical opening of the motor mounting base 312.
[0104] The drive motor 21 is inserted into the motor mounting base 312, and the output shaft of the drive motor 21 passes through the opening of the motor mounting base 312 and enters the inner cavity of the first connecting arm 32, so that the brush head 1 can be driven by the aforementioned transmission assembly 22.
[0105] In some embodiments, a shock-absorbing sleeve 313 is provided inside the motor mounting base 312, and the shock-absorbing sleeve 313 is located between the motor mounting base 312 and the housing of the drive motor 21. The shock-absorbing sleeve 313 is configured to be sleeved on the housing of the drive motor.
[0106] In some embodiments, the damping sleeve 313 includes a damping sleeve body 3131 sleeved on the outer peripheral surface of the drive motor 21, and a damping sleeve covering portion 3132 extending to cover the output shaft end cap of the drive motor 21, the damping sleeve covering portion 3132 having a shaft through opening. This provides good damping effect while also effectively reducing noise.
[0107] In some embodiments, the shock-absorbing sleeve 313 may be made of elastic plastic materials such as silicone or rubber.
[0108] In some embodiments, a sealing ring 314 is provided on the sealing cover 323 at the cover edge that mates with the first connecting arm 32. After the cover is closed, the sealing ring 314 can effectively reduce the noise transmitted from the first connecting arm 32.
[0109] In some embodiments, the first connecting arm 32 is provided with an axial connecting stud 326 inside, and the inner side of the sealing cover 323 corresponding to the inner cavity of the first connecting arm 32 has a positioning connecting sleeve 327 that cooperates with the axial connecting stud. The outer side of the sealing cover 323 is provided with a threaded interface corresponding to the positioning connecting sleeve 327.
[0110] The sealing cover 323 is oriented and covered on the first connecting arm 32 by the positioning connecting sleeve 327 and the positioning sleeve of the axial connecting stud 326. The sealing cover 323 is connected to the axial connecting stud 326 by the screw passing through the screw interface, forming a detachable connection with positioning effect.
[0111] In some embodiments, the second connecting arm 33 has a switchable first state and a second state relative to the base 31. In the first state, the second connecting arm 33 can act as an anti-disengagement barrier against the output shaft 113 inserted on the connecting shaft; in the second state, the second connecting arm 33 can act as a release from the anti-disengagement barrier against the output shaft 113 inserted on the connecting shaft.
[0112] By switching between the first and second states, the brush head 1 can be detachably connected to the brush body 3, that is, the connection between the output shaft 113 and the connecting shaft 221 is detachable.
[0113] In some embodiments, when the second connecting arm 33 is configured to prevent the output shaft 113 inserted on the connecting shaft from disengaging, the second connecting arm 33 can also simultaneously support the output shaft 113, that is, rotate in cooperation with the output shaft 113.
[0114] In some embodiments, a locking component 34 is provided between the second connecting arm 33 and the base 31. The locking component 34 is used to lock the second connecting arm 33 onto the base 31 when the second connecting arm 33 is in a first state; the locking component 34 is also used to unlock the second connecting arm 33 locked onto the base, so that the second connecting arm 33 can change to a second state.
[0115] In some embodiments, the second connecting arm 33 is detachably connected to the base 31, with the first state corresponding to the connected state and the second state corresponding to the detached state.
[0116] In some embodiments, the locking assembly 34 includes a threaded portion 341 located on the side of the base 31, and a threaded engagement member 342 located on the second connecting arm 33; the threaded portion 341 and the threaded engagement member 342 can be threaded into each other.
[0117] After the second connecting arm 33 approaches the base 31, the second connecting arm 33 can be connected to the base 1 by screwing the screw connection part 341 and the screw connection mating part 342.
[0118] Specifically, the threaded portion 341 is, for example, a structural member with a threaded hole provided on the base, such as a threaded post or nut, which is restricted from detaching from the base in a direction close to the second connecting arm. For example, the threaded post is integrally formed on the base, or the base has a retaining bracket for limiting the nut.
[0119] The screw-fit part 342 is, for example, a knob having a screw portion and a cap portion. The second connecting arm has a connecting hole corresponding to the screw hole of the screw portion. The screw portion of the knob passes through the connecting hole and is screwed onto the screw portion. The cap portion of the knob presses the second connecting arm tightly onto the base.
[0120] In some embodiments, a first elastic element 343 is provided between the knob and the second connecting arm 33. When the screw portion of the knob is screwed into the screw hole of the screw connection portion, the first elastic element 343 is elastically deformed by the combined action of the knob and the second connecting arm 33. The provision of the first elastic element 343 makes the connection more stable and less prone to loosening, especially when the second connecting arm 33 supports the output shaft 113, it can better prevent the screw connection from loosening.
[0121] In some embodiments, the first elastic element 343 includes a compression spring sleeved on the screw portion of the knob.
[0122] In some embodiments, at the point where the second connecting arm 33 and the base 31 come into contact, the base 31 has a support arm positioning part 315, and the second connecting arm 33 has a support arm positioning mating part 331. The positioning mating of the support arm positioning part 315 and the support arm positioning mating part 331 prevents the second connecting arm 33 from rotating and shifting after it is screwed and tightened, so as to better limit and support the brush head 1.
[0123] In some embodiments, the output shaft 113 has a conical end face 1131 at one end corresponding to the second connecting arm, and the second connecting arm 33 is provided with a conical hole 332 that mates with the conical end face. Through the inclined surface characteristics of the conical end face 1131, the second connecting arm 33 is more easily aligned and supported with the output shaft 113, and the second connecting arm 33 is also more easily separated from the output shaft 113 when disassembling the second connecting arm.
[0124] In some embodiments, the output shaft 113 and the connector 11 are detachably connected. For example, the connector 11 has a central shaft hole, and the output shaft 113 is correspondingly inserted into the central shaft hole. It can be understood that the connector 11 is sleeved on the output shaft 113. In this way, the brush head 1 has multiple individually detachable components, including the output shaft 113, the connector 11, and the contact cleaning component 12, which allows for further refinement of the replacement cost of the brush head 1, enabling targeted replacement of damaged components and facilitating more comprehensive cleaning of the brush head 1.
[0125] In some embodiments, the radial cross-sectional shape of the central shaft hole is non-circular, and the radial cross-sectional shape of the shaft segment passing through the central shaft hole on the output shaft 113 is correspondingly non-circular, so that the output shaft 113 can better drive the connecting member 11 to rotate. The non-circular shape is, for example, a regular hexagon.
[0126] In some embodiments, a support member 5 is also provided on the brush body 3. The support member 5 is provided on the brush body 3 and located behind the brush head 1. The support member 5 is configured to be located between the brush head 1 and the handheld part 4. When the user holds the handheld part 4 and presses the brush head 1 against the mesh-like object, the support member 5 can be supported on the mesh-like object to form a force fulcrum, so that the user can better maintain the stability and balance of the electric cleaning brush.
[0127] In some embodiments, the support member 5 has a proximal end connected to the brush body 3 and a distal end having a support for contacting a mesh-like article; a roller 51 for contacting the mesh-like article is provided on the distal end of the support member 5.
[0128] In some embodiments, the axial direction of the roller 51 on the support 5 is the same as the axial direction of the brush head 1. The arrangement of the roller 51 allows the support 5 to provide better support during movement of the brush when the brush is moved back and forth.
[0129] In some embodiments, the proximal end of the support member 5 is movably connected to the brush body 3. The movement of the support member 5 on the brush body 3 makes the support opening provided by the support member 5 variable.
[0130] Support opening indicates that when the brush head 1 contacts the item and the support member 5 supports the item, the different positions of the support member 5 can cause the degree to which the handle 4 is close to the item, or the angle of the handle 4 to change accordingly.
[0131] In some embodiments, the support member 5 is movably connected to the brush body 3, for example, by a rotatable connection, and the support opening provided by the support member 5 is variable by rotating the support member 5.
[0132] For example, the proximal end of the support member 5 is provided with a rotating connection part 52, and the brush body 3 is provided with a corresponding rotating mating part (not shown). The proximal end of the support member 5 is rotatably connected to the brush body 3 through the cooperation of the rotating connection part 52 and the rotating mating part.
[0133] For example, the rotating connecting part 52 is a rotating shaft, and the rotating mating part is a rotating shaft seat that mates with the rotating shaft.
[0134] When the provided support opening decreases, it can be understood as rotating the support 5 so that the far end is closer to the brush head 1; when the provided support opening increases, it can be understood as rotating the support 5 so that the far end is further away from the brush head 1.
[0135] In some embodiments, the brush body 3 is further provided with a rotation amount limiting part 35 to limit the rotation amount of the support member 5, thereby limiting the minimum support opening and the maximum support opening.
[0136] At the minimum support opening, the support member 5 does not contact the brush head 1, or it can be understood that there is a redundant gap between the support member 5 and the brush head 1 to prevent the support member 5 from affecting the rotation of the brush head 1; at the maximum support opening, the support member 5 does not contact the handheld part 4, or it can be understood that there is a safe distance between the support member 5 and the handheld part 4 to prevent the support member 5 from hitting the user's hand holding the handheld part 4.
[0137] In some embodiments, a second elastic member 53 is also provided between the support member 5 and the brush body 3.
[0138] When the support member 5 moves to increase the support opening, the second elastic member 53 is subjected to the combined action of the support member 5 and the brush body 3 to undergo elastic deformation, or to increase the elastic deformation. Thus, when the external force is removed, the second elastic member 53 can apply a spring force to the support member 5, causing the support member 5 to move to decrease the support opening. In other words, the second elastic member 53 can provide kinetic energy for the movement of the support member 5 after elastic deformation.
[0139] like Figure 11 As shown, in some embodiments, when the support member 5 is rotatably connected to the brush body 3, the second elastic member 53 may include, for example, a torsion spring 53a. When the support member 5 rotates to increase the support opening, the two force-bearing ends of the torsion spring 53a are pressed by the support member 5 and the brush body 3 respectively, causing the torsion spring 53a to be in torsional deformation or in greater torsional deformation.
[0140] like Figure 10 As shown, in some embodiments, when the support member 5 is rotatably connected to the brush body 3, the second elastic member 53 may include, for example, a spring shaft 53b, which is disposed between the rotatable connection portion 52 and the rotatable mating portion. Specifically, for example, both the rotatable connection portion 52 and the rotatable mating portion have mounting grooves 521. The outer sleeve of the spring shaft 53b is positioned and inserted into the mounting groove of the rotatable mating portion, and the rotating block of the spring shaft 53b is positioned and inserted into the mounting groove of the rotatable connection portion 52. When the support member 5 rotates to increase the support opening, the spring shaft 53b is acted upon by the combined action of the rotatable connection portion 52 and the rotatable mating portion, and the internal elastic component of the spring shaft 53b correspondingly generates elastic deformation or greater elastic deformation.
[0141] By adjusting the opening angle and incorporating the second elastic element 53, the support member 5 provides better shock absorption during support. Furthermore, when the support is in motion, the roller 51 allows it to traverse uneven surfaces more effectively, preventing jamming during movement. Additionally, when the user grips the handle 4 and presses down, the angle of the handle 4 can be adjusted within the support opening range to regulate the applied force.
[0142] In some embodiments, the support member 5 is provided with a mudguard 54, which is used to block water stains or particles, reducing the splashing of water stains or particles onto the handheld part or the user behind during cleaning.
[0143] In some embodiments, the support member 5 is provided with a plurality of reinforcing ribs 55 to further enhance the support strength of the support member 5.
[0144] In some embodiments, the reinforcing rib 55 is disposed on the side of the support member 5 away from the brush head 1 to prevent water stains or particles splashed from the brush head from directly adhering to the corner gap formed by the reinforcing rib.
[0145] In some embodiments, the support member 5 may be a structural member with high support strength, such as a metal material or a rigid plastic material.
[0146] In some embodiments, when the aforementioned support member 5, second elastic member 53, and brush head 1 with bristles are simultaneously provided, and the brush head 1 has bristle connecting portions 123 extending to both ends of the connector 11: the drive motor 21 has a rotational output state for driving the brush head 1 to brush the mesh-like item backward, that is, the brush head 1 has a backward brushing rotational cleaning state. At this time, the backward brush bristles 122 and the support member 5, which is powered by the second elastic member 53, can simultaneously form a clamping effect on the mesh-like item, resulting in a better cleaning effect.
[0147] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
