Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-11 An electric cleaning tool for cleaning gridded cooking surfaces includes a handle 1, a drive unit 2, and a cleaning head 3. The handle 1 is suitable for one-handed or two-handed use. The cleaning head 3 can be used to clean gridded cooking surfaces, such as grills, ovens, and other gridded cooking surfaces.

[0021] In this embodiment, the drive unit 2 is replaceably mounted on the handle 1.

[0022] In some embodiments, the cleaning head 3 is replaceably mounted on the drive unit 2.

[0023] In some embodiments, the drive unit 2 has an electric drive member 201. When the cleaning head 3 is disposed on the drive unit 2, the electric drive member 201 is configured to drive the cleaning head 3 so that the cleaning head 3 performs a cleaning action that can clean a gridded cooking surface such as a grill, oven, or baking oven.

[0024] In some embodiments, the electric cleaning tool further includes a first locking structure 4, which has a switchable first locked state and a first unlocked state.

[0025] When the drive unit 2 is mounted on the handle 1, the first locking state of the first locking structure 4 is configured to hold the drive unit 2 on the handle 1; the first unlocking state is configured to release the first locking structure 4 from holding the drive unit 2 on the handle 1, that is, at this time the drive unit 2 can be easily removed from the handle 1 or separated from the handle.

[0026] In some embodiments, a first electrical module is provided on the handle 1, and a second electrical module is provided on the drive unit 2.

[0027] When the drive unit 2 is mounted on the handle 1, the first electrical module can be electrically connected to the second electrical module.

[0028] In some embodiments, the first locking state of the first locking structure 4 further constitutes an electrical connection between the first electrical module and the second electrical module, or a stable electrical connection between the first electrical module and the second electrical module.

[0029] In some embodiments, the first electrical module includes a power supply module 101, and the electric drive unit 201 is included in the second electrical module, that is, the second electrical module includes the electric drive unit.

[0030] The power module 101, through the electrical connection between the first and second electrical modules, can provide at least the electrical power required to drive the electric drive unit 201.

[0031] In some embodiments, the handle 1 is provided with a handle end control unit 102 and a handle end command input unit 103.

[0032] The handle-end control unit 102, based on user input commands received from the handle-end command input unit 103, enables the first electrical module to controllably output different electrical signals to the second electrical module. For example, it outputs different currents or voltages. Specifically, it enables the first electrical module to controllably output controls related to cleaning cooking surfaces to the second electrical module.

[0033] In some embodiments, the handle-end command input unit 103 may be, for example, an input unit such as a button, button panel, or touch panel provided on the handle that allows the user to input control commands when touching the handle.

[0034] In some embodiments, the command input unit at the handle end is, for example, a wireless unit disposed on the handle. For instance, the wireless unit wirelessly connects to a wireless mobile device, and the corresponding command is input via the wireless mobile device.

[0035] For example, a wireless unit can be used to wirelessly connect to a mobile phone, and control commands can be input through the corresponding APP or mini-program on the mobile phone. The wireless connection enables the control unit at the end of the handle to receive the corresponding command signals.

[0036] In some embodiments, the electric drive 201 is, for example, a motor, which drives the cleaning head to perform a cleaning action that can clean grills, ovens, gridded cooking surfaces such as grills, ovens, and ovens.

[0037] In some embodiments, the user may input motor on / off control via a command input unit at the handle end.

[0038] In some embodiments, the user may input motor speed adjustment control via a command input unit at the handle end.

[0039] In some embodiments, the first electrical module can controllably output different currents to the second electrical module, thereby controlling different speeds of the motor.

[0040] In some embodiments, the drive unit 2 is also provided with additional electrical components other than the electric drive component, such as the lighting lamp 202. That is, the second electrical module also includes additional electrical components other than the electric drive component, such as the lighting lamp 202.

[0041] The power module 101 can also be used to power additional electrical components other than the electric drive components such as the lighting lamp 202.

[0042] In some embodiments, the user may input adjustment control of additional electrical components, such as turning the light on / off, or further, adjusting the brightness of the light, through the command input unit at the handle end, so that corresponding illumination can be obtained when cleaning the grilled cooking surface, thereby facilitating the cleaning of the grilled cooking surface.

[0043] In some embodiments, the drive unit is further provided with a drive end control unit (not shown). The handle end control unit receives commands input by the handle end command input unit and outputs corresponding electrical signals to the drive end control unit through the electrical connection between the first electrical module and the second electrical module. The drive end control unit receives the electrical signals and performs corresponding control. For example, controlling the motor speed, controlling the lighting to work / stop, etc.

[0044] For example, a user inputs a motor speed adjustment command through the command input unit on the handle. The control unit on the handle receives the corresponding command signal and outputs the corresponding command signal to the control unit on the drive end. After receiving the corresponding command signal, the control unit on the drive end controls the supply of the corresponding power to the motor to control the change of the motor speed.

[0045] For example, a user inputs a command to turn on the light through the command input unit on the handle. The control unit on the handle receives the corresponding command signal and outputs the corresponding command signal to the control unit on the drive end. After receiving the corresponding command signal, the control unit on the drive end controls the power supply to the light so as to turn on the light.

[0046] In some embodiments, the handle 1 is further provided with a fluid delivery device 104.

[0047] A fluid nozzle 203 is provided on the drive unit 2. When the drive unit 2 is provided on the handle 1, the fluid delivery device 104 is configured to deliver fluid to the fluid nozzle 203, so that the fluid is ejected through the fluid nozzle 203.

[0048] Combination Figure 2 , 5 As shown, in some embodiments, the fluid nozzle 203 is configured with multiple types, that is, when replacing the drive unit 2, different types of fluid nozzles can be selectively replaced at the same time or different types of fluid nozzles can be not replaced.

[0049] For example, different types of fluid nozzles are provided on the same type of drive unit (such as an electric drive unit with the same design); or different types of fluid nozzles are provided on different types of drive units (such as an electric drive unit with the same design).

[0050] Users can optionally replace the drive unit with the corresponding type, and when replacing the drive unit, they can choose whether to also change the type of fluid nozzle.

[0051] In some embodiments, different types of fluid nozzles include, for example: A fluid nozzle having one orifice or fewer orifices for concentrating the jet flow, for example, allowing fluid to be rapidly ejected from the orifice of the fluid nozzle at the same pressure; Fluid nozzles with multiple orifices are designed for large-area jetting, allowing for simultaneous jetting of a larger area. A fluid nozzle with atomizing orifices is used to atomize the fluid ejected from the atomizing orifices, or to atomize and vaporize the fluid before or upon contact with a hot surface when cleaning a hot grill.

[0052] In some embodiments, the fluid may be stored in the storage space of the fluid delivery device 104 in the form of a liquid, and may be converted into a mist or sprayed out in the form of steam.

[0053] In some embodiments, the fluid delivery device includes a container disposed on a handle, the container being capable of storing and dispensing liquids, such as water or other cleaning solutions.

[0054] For example, the user can apply pressure to the container on the handle via an optional manual pump to pressurize the liquid inside the container and supply it to the fluid nozzle; or, the user can connect the container to a water pump and input the start of liquid release via the command input unit at the handle end, so that the water pump can work to pressurize the liquid inside the container and deliver it to the fluid nozzle, thereby achieving an electrically controlled supply.

[0055] Unlike the above embodiments, in this embodiment, the fluid delivery device 104 includes a container 1041 disposed outside the handle 1, and a delivery pipe 1042 disposed on the handle 1, the delivery pipe 1042 being connected to the container 1041 or to the fluid supply port of the container.

[0056] For example, container 1041 can be configured as a water tank to store more liquid. Container 1041 and handle 1 are separated, with only the delivery pipe 1042 for communication remaining on handle 1, which can better reduce the grip weight of handle 1.

[0057] For example, the user can apply pressure to the container via an optional manual pump to pressurize the liquid inside the container and supply it to the fluid nozzle through the delivery pipe; or, the user can connect the container 1041 to a water pump and input the start of liquid release via the instruction input unit 103 at the handle end, so that the water pump can work to pressurize and deliver the liquid inside the container 1041 to the fluid nozzle 203 to achieve electronically controlled supply.

[0058] In some embodiments, the fluid delivery device further includes an atomizer or evaporator for atomizing the liquid supplied to the fluid nozzle to obtain a mist fluid, or for heating the liquid supplied to the fluid nozzle to obtain steam, so as to spray out hot mist that is more conducive to cleaning the grill, oven, or other gridded cooking surfaces.

[0059] In some embodiments, the first locking structure 4 includes a first male connector 401 and a first female connector 402 that are plugged into each other along a first direction.

[0060] The first locking structure 4 also includes an elastic locking component for holding the first female connector 402 and the first male connector 401 together after the first male connector 401 and the first female connector 402 are mutually inserted and engaged. The elastic locking component applies a certain elastic force to keep the first female connector 402 and the first male connector 401 in the inserted state, so that the first female connector 402 and the first male connector 401 are not easily separated during use.

[0061] In some embodiments, the first male head 401 of the first locking structure may be disposed on the handle 1, for example, disposed at the front end of the handle 1.

[0062] The first female seat 402 of the first locking structure may be provided on the driving part 2, for example, at the rear end of the driving part 2.

[0063] In some embodiments, the first female connector 402 has a space for accommodating the insertion of the first male connector 401. The insertion space has an insertion opening suitable for the insertion of the first male connector, and an inner front wall corresponding to the insertion opening and an inner side wall located between the inner bottom wall and the insertion opening are formed based on the insertion space.

[0064] The first male head 401 has an end face corresponding to the inner front wall of the insertion space and an outer side face corresponding to the inner side wall of the insertion space.

[0065] The resilient locking assembly includes a slot 403 disposed on the inner sidewall of the first female seat 402.

[0066] The outer surface of the first male head 401 is formed with a receiving groove 404.

[0067] The resilient locking assembly also includes a retaining spring (not shown) and a retaining block 406 disposed within a receiving groove.

[0068] After the first male connector 401 and the first female connector 402 are inserted into place, the slot 403 is configured to correspond to the retaining block 406 on the receiving groove 404. The retaining spring is configured to push a part of the retaining block 406 out of the receiving groove 404 and engage a part of the retaining block 406 in the slot 403, thereby preventing the separation of the first male connector 401 and the first female connector 402, so that the first male connector 401 and the first female connector 402 are retained by the elastic locking assembly.

[0069] In some embodiments, the depth direction of the receiving groove 404 on the first male head 401 is perpendicular to the insertion direction of the first male head 401 into the first female head 402, that is, the depth direction is perpendicular to the first direction.

[0070] In some embodiments, the retaining block 406 also has a guide ramp 407 or a guide arc surface corresponding to the side wall of the slot 403 or the opening edge of the slot, so that when the user actively applies a large separation force (applying force in the direction opposite to the insertion direction) to the drive unit 2 and the handle 1, the side wall of the slot 403 or the opening edge of the slot can be pushed out of the slot 403 by the guide ramp 407 or the guide arc surface, so that the retaining block 406 moves in the direction of the retractable receiving groove 404, so that the first male head 401 and the first female head 402 can be separated under the active force of the user, for example, it can be used to replace the drive unit.

[0071] In some embodiments, the first electrical module and the second electrical module are electrically connected, for example, through PIN contact.

[0072] For example, the first male connector 401 is provided with multiple POGO PINs 408 (spring pins), and the first female connector 402 is provided with multiple corresponding metal contacts 409.

[0073] After the first male connector 401 and the first female connector 402 are inserted into place, the POGO PIN 408 makes contact with the corresponding metal contact 409.

[0074] The terminals or leads of the first electrical module are connected to the POGO PIN, and the terminals or leads of the second electrical module are connected to the metal contacts.

[0075] The POGO PIN and metal contact can also be set to interchange positions, for example, the POGO PIN can be set on the first female connector and the metal contact can be set on the first male connector.

[0076] In some embodiments, the extension / retraction direction of the POGO PIN 408 is the same as the insertion direction of the first male connector 401. For example, the POGO PIN is disposed on the front end face of the first male connector 401, and the extension / retraction direction of the POGO PIN is forward and backward. The first male connector 401 is inserted forward into the first female connector 402.

[0077] In some embodiments, the plurality of terminals includes a corresponding power supply terminal. In other embodiments, the plurality of terminals also includes a corresponding signal terminal.

[0078] In some embodiments, the drive unit 2 is provided with a drive end connector 204 that communicates with the inlet of the fluid nozzle 203. The handle 1 is provided with a handle end connector 105 that communicates with the outlet of the delivery pipe 1042. When the first male connector 401 and the first female connector 402 are inserted into place, the drive end connector 204 and the handle end connector 105 are mutually engaged.

[0079] For example, the drive end connector is sleeved on the outside of the handle end connector, or the handle end connector 105 is sleeved on the outside of the drive end connector 204.

[0080] In some embodiments, the front end face of the first male connector 401 is provided with an opening, and the handle end connector 105 is disposed inside the handle 1 and exposed through the opening of the first male connector 401.

[0081] The drive end insertion tube 204 is disposed on the inner front wall of the first female seat 402, and the drive end insertion tube 204 extends rearward accordingly, forming an insertion space that does not extend rearward beyond the first female seat 402.

[0082] Thus, within the insertion space of the first female connector 402, the extension length of the drive end connector 204 can be set to be longer, and the first female connector 402 can protect the drive end connector 204 without worrying about the drive end connector 204 being easily damaged.

[0083] The extended length of the drive end connector 204 allows for a greater insertion depth between the drive end connector 204 and the handle end connector 105, thus providing sufficient length between the drive end connector 204 and the handle end connector 105 for setting a leak-proof structure.

[0084] For example, a sealing ring can be set on the outer circumferential surface of the drive end connector 204, or multiple sealing rings can be set at intervals on the outer circumferential surface of the drive end connector along the length direction of the drive end connector. The handle end connector 105 is sleeved on the drive end connector 204. The sealing ring is used to seal the gap between the two pipes to achieve a better leak-proof effect.

[0085] In some embodiments, the positions of the first male connector 401 and the first female connector 402 can be different. For example, the first male connector can be positioned on the drive unit, while the first female connector can be positioned on the handle. After the first male connector and the first female connector are plugged in, the aforementioned electrical connection can be established, the aforementioned locking can be performed, and when a fluid conveying device is provided, the two can smoothly form a fluid conveying mechanism.

[0086] In some embodiments, the first male connector 401 is further provided with a positioning guide rail 410 corresponding to the first direction, and the first female connector 402 is provided with a positioning guide post 411 that cooperates with the positioning guide rail 410. When the connector is inserted, the positioning guide post 411 and the positioning guide rail 410 can guide the first male connector 401 and the first female connector 402 to be more accurately aligned.

[0087] In other embodiments, the relative positions of the positioning guide rail 410 and the positioning guide post 411 can also be interchanged. For example, the positioning guide rail is disposed on the first female seat, and the positioning guide post is disposed on the first male head.

[0088] In some embodiments, the power module 101 includes a battery 1011 disposed in the handle 1, which can be easily moved and used.

[0089] In some embodiments, the length direction of the battery 1011 is the same as the length direction of the handle 1, such as both being arranged in a front-to-back direction.

[0090] In some embodiments, the delivery tube 1042 is configured within the handle 1 to deliver fluid from the rear end of the handle 1 to the front end of the handle 1.

[0091] In some embodiments, the handle 1 is provided with at least one partition 106, which is disposed between the delivery pipe 1042 and the battery 4011.

[0092] For example, when transporting steam at a high temperature through the delivery pipe, the multi-layered partitions or partitions mentioned above constitute a heat insulation structure to reduce the thermal impact of the steam on the battery.

[0093] In some embodiments, the electric cleaning tool further includes a second locking structure 5, which has a switchable second locking state and a second unlocking state.

[0094] When the cleaning head 3 is mounted on the drive unit 2, the second locking state of the second locking structure 5 holds the cleaning head 3 on the drive unit 2. The second unlocking state causes the second locking structure to release the cleaning head 3 from the drive unit 2, that is, the cleaning head can be easily removed from or separated from the drive unit.

[0095] In some embodiments, the drive unit 2 is provided with a power output structure corresponding to the electric drive component 201.

[0096] The cleaning head 3 is equipped with a power receiving structure.

[0097] The second locking state of the second locking structure 5 also enables the power output structure to be connected to the power receiving structure. At this time, the electric drive unit 201 can output power to the power receiving structure through the power output structure, so that the cleaning head can receive the power of the electric drive unit and perform the cleaning action.

[0098] Combination Figure 1 , 3 As shown in Figures 5 and 9, in this embodiment, different types of drive units are, for example, electric drive components with different designs. For instance, the motor of the first drive unit is arranged perpendicular to the length direction of the handle, while the motor of the second drive unit is arranged parallel to the length direction of the handle.

[0099] Users can choose to replace different types of drivers according to their different usage needs.

[0100] Please refer to details. Figure 1-4 In some embodiments, the motor structure design of the first part of the drive unit and the structure design of the replaceable cleaning head can refer to the similar structure shown in Chinese patent application CN120458347A.

[0101] The first part of the drive unit includes a main body 21 and two forward-extending connecting arms, namely a first connecting arm 22 and a second connecting arm 23, wherein the second connecting arm 23 is detachably connected to the main body 21.

[0102] The aforementioned first male or first female connector is connected to the main body. A motor (length direction or axial direction) perpendicular to the length direction of the handle is correspondingly installed in the main body 21. A power transmission component, such as a gear set (not shown), is provided in the first connecting arm 22.

[0103] The power transmission assembly has an axial slot formed on the first connecting arm 22, such as an axial slot provided on the end face of the output gear of the gear set. The axial slot faces the second connecting arm 23, and the first connecting arm 22 has an opening corresponding to the axial slot.

[0104] The spacing direction of the first connecting arm 22 and the second connecting arm 23 is the same as the axial direction of the motor.

[0105] At this time, the cleaning head set on the first part of the drive unit has a connecting shaft 309, one end of which is inserted into the axial slot, and the cleaning head is driven to rotate by the motor through the power transmission assembly.

[0106] The second connecting arm 23 has a shaft hole or tapered hole corresponding to the connecting shaft 309. The second connecting arm 23 is connected to the main body 21 and the shaft hole or tapered hole is matched with the other end of the connecting shaft 309 to support the connecting shaft 309 and restrict the cleaning head from coming out of the axial slot.

[0107] For example, the second connecting arm 23 is connected to the main body 21 via a locking assembly 501 that includes a screw-fitting component.

[0108] That is, the second connecting arm 23 is connected to the main body 21 by a locking assembly 501 including a screw-fitting member to form the second locking state of the second locking structure 5 described above.

[0109] The screw-fit component is removed, and the second connecting arm is connected to the main body to form the second unlocked state of the aforementioned second locking structure.

[0110] The power transmission components (such as gear sets) constitute the power output structure described above, and the connecting shaft on the cleaning head constitutes the power receiving structure described above.

[0111] Please refer to details. Figure 5-11 In some embodiments, the second drive unit includes a main body 21, the aforementioned first male or first female connector is connected to the main body 21, and a motor parallel to the length direction of the handle is correspondingly disposed in the main body 21.

[0112] The cleaning head 3 includes a mounting body 301, on which a cleaning output shaft 302 is rotatably connected, and a brush 303 is connected to the cleaning output shaft 302. The brush 303 can take various forms, such as a bristle brush or a mesh brush.

[0113] A groove 304 is provided at the eccentric position of the cleaning output shaft 302.

[0114] The mounting body 301 is also rotatably connected to a power connection shaft 305. One end of the power connection shaft 305 is connected to a toggle block 306. The toggle block 306 is connected to an aggle part 307 that cooperates with the slide groove 304 at an eccentric position.

[0115] When the power connection shaft 305 rotates in one direction, the actuating part 307 actuates the two opposite side walls of the slide groove 304 back and forth, causing the cleaning output shaft 302 to continuously change direction and output, so as to drive the brush 303 to quickly change direction and rub the grill, oven, oven and other gridded cooking surfaces.

[0116] like Figure 10 As shown, the axial direction of the power connection shaft 305 and the axial direction of the cleaning output shaft 302 can be set to be offset at a certain angle, without having to be exactly the same axial direction.

[0117] The other end of the power connection shaft 305 is connected to a first engagement portion 308, and the output shaft of the motor is connected to a second engagement portion 205 that mates with the first engagement portion. For example, the first engagement portion 308 has a cross-shaped engagement groove, and the second engagement portion 205 is arranged in a cross shape.

[0118] In some embodiments, the second locking structure 5 includes a second male connector 502 and a second female connector 503 that are plugged into each other. For example, the second male connector 502 is located at the front end of the second driving part, and the second female connector 503 is located at the rear end of the mounting body 301.

[0119] When the second male connector 502 and the second female connector 503 are inserted, the second joint portion 205 is correspondingly inserted into the joint groove of the first joint portion 308. The second joint portion 205 constitutes the power output structure described above. The power connection shaft 305 having the first joint portion constitutes the power receiving structure described above.

[0120] In some embodiments, the power connection shaft 305 is configured to pass through an insertion space in the second female seat 503.

[0121] The second male head 502 is cylindrical in shape, and the second joint 205 is formed to pass through the internal space of the second male head 502.

[0122] In some embodiments, a locking slider 504 is formed on the inner sidewall of the second female seat 503.

[0123] The outer peripheral surface of the second male head 502 is formed with a guide groove 505, which extends forward to connect with the front end face of the second male head 502, forming a sliding entrance suitable for locking the slider 504 to slide in.

[0124] The portion of the guide groove 505 away from the slide entrance extends along the outer peripheral surface of the second male head 502 to form a locking groove 507 suitable for locking the slider into place.

[0125] Preferably, an elastic locking point 508 is also provided at the entrance of the locking groove 507, so that after the locking slider 504 enters the locking groove 507, under the elastic force restriction of the elastic locking point 508, the locking slider 504 is not easy to return from the locking groove 507 to the guide groove 505.

[0126] That is, the locking slider entering the locking groove constitutes the second locking state of the second locking structure described above. The locking slider retracting from the locking groove to the guide groove constitutes the second unlocking state of the second locking structure described above.

[0127] In some implementations, the elastic locking point 508 can be integrally molded onto the second male connector 502, which may be made of plastic and have a certain elastic deformation capability.

[0128] In some embodiments, the power module, the handle end control unit, and the handle end command input unit are all mounted on the handle, and the second electrical module on the drive unit is controlled by the handle end control unit.

[0129] For example, the motor speed is directly controlled by the control unit at the handle end, which controls the amount of current transmitted to the motor by the power module.

[0130] In other words, the power supply, command input, and control unit are all concentrated on the handle, which effectively reduces the cost of replacing the drive unit and the difficulty of setting up the drive unit's electronic control part when replacing different types of drive units.

[0131] As relatively fragile electronic control components, the power module and the handle end control unit remain on the handle and are held by the user. Even if the drive unit separates from the handle during use, the safety of the handle held by the user and the power module and handle end control unit installed on the handle can be well ensured.

[0132] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
