Description

Technical Field

[0001] This invention relates to the field of barbecue cleaning brush technology, specifically to a double-headed cleaning brush. Background Technology

[0002] In daily life and catering settings, the grill rack, as a core component of barbecue equipment, is prone to accumulating food residue, grease, and other contaminants. Inadequate cleaning not only affects the taste and hygiene of the grilled food but can also lead to bacterial growth due to accumulated dirt, shortening the grill rack's lifespan. Currently, most grill rack cleaning brushes on the market employ a fixed design, with a single brush head fixed to a support body. Cleaning requires manual handling of the support body, moving it back and forth to clean the grill rack.

[0003] However, this type of cleaning brush with a single fixed brush head has many drawbacks in actual use: On the one hand, the cleaning range of a single brush head is limited, and it is not thorough in cleaning the mesh gaps, corners, and other areas of the grill, requiring repeated wiping and resulting in low cleaning efficiency; on the other hand, although some improved cleaning brushes have added a rotating power component to drive the brush head to rotate and improve the cleaning effect, since only a single rotating brush head is set, a large rotational torque will be generated during the rotation. This torque acts on the support body, which can easily cause the entire cleaning brush to vibrate significantly. This not only affects the comfort of holding the brush, but also causes the brush head to deviate during the cleaning process, making it difficult to accurately align with the cleaning area, further reducing the cleaning accuracy and efficiency. Long-term use may also cause the support body, power component, and other parts to loosen due to vibration, shortening the service life of the cleaning brush.

[0004] Therefore, in view of the problems of low cleaning efficiency, obvious vibration and easy deviation of the existing grill cleaning brush fixing structure, developing a grill cleaning brush that can solve the above-mentioned technical pain points has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0011] Preferably, the dual-headed cleaning brush includes a locking device, which includes a press-type locking member. The press-type locking member is movably disposed on the support body, and the locking end of the press-type locking member is configured as a contour-fitting tooth. Pressing down the press-type locking member enables the contour-fitting tooth to engage with the first output gear or the second output gear without clearance.

[0012] Preferably, the dual-head cleaning brush includes a lighting device, which includes an LED illumination module, and the LED illumination module is fixedly mounted on the support body.

[0013] Preferably, the dual-head cleaning brush includes a water washing device, which includes a water tank, a spray nozzle assembly, and a water spray power assembly, wherein: the water tank is disposed on the support body; the spray nozzle assembly is disposed between the first brush head assembly and the second brush head assembly, and the spray nozzle assembly is connected to the water tank through a water supply pipeline; the water spray power assembly is disposed on the water supply pipeline.

[0014] Preferably, the spray nozzle assembly includes a spray nozzle and a dispersion plate, wherein: the spray nozzle is fixedly mounted on the support body, and the top inlet of the spray nozzle is connected to the outlet of the water supply pipeline; the dispersion plate is disposed at the bottom outlet of the spray nozzle, and the dispersion plate has multiple dispersion outlets arranged circumferentially.

[0016] Preferably, the dual-head cleaning brush includes an electronic control device, which includes a power supply, a control board, and control buttons, wherein: the control board is electrically connected to the power supply; the control buttons are disposed on the control board; and the rotary power assembly, the LED illumination module, and the water spray power assembly are all electrically connected to the control board.

[0017] Preferably, the support body includes a handle and a support head, the support head is disposed at the front end of the handle, and the cleaning brush device, the water washing device and the mudguard device are disposed on the support head.

[0018] The dual-headed cleaning brush provided by this invention has at least the following beneficial effects: I. Improve cleaning efficiency and cleaning effect: The cleaning brush device is equipped with a first brush head assembly and a second brush head assembly. The two brush heads work synchronously, effectively expanding the cleaning coverage area compared to a single brush head. It can clean different areas of the grill mesh simultaneously, especially for hard-to-clean areas such as mesh gaps and corners. The cooperation of the two brush heads can achieve all-round cleaning, reducing the number of repeated wipings and significantly improving cleaning efficiency. At the same time, the rotating power assembly drives the two brush heads to rotate through the transmission assembly. Rotational cleaning, compared to traditional reciprocating wiping, can more efficiently remove stubborn residues and grease from the grill mesh surface, further improving the cleaning effect and ensuring a thorough cleaning of the grill mesh. In addition, the water spray assembly wets the grill mesh, further improving cleaning efficiency and adsorbing smaller solid particles, reducing dust generation and further enhancing the cleaning effect.

[0019] II. Counteract rotational torque and reduce vibration and deviation: The rotary power assembly drives the first and second brush head assemblies to rotate synchronously in opposite directions via the transmission assembly. The core advantage of this design is that it can effectively cancel out the rotational torque generated when a single brush head rotates. That is, the two brush heads rotate synchronously in opposite directions, and the rotational torques they generate are opposite in direction and equal in magnitude, thus canceling each other out. This significantly reduces the vibration amplitude during the cleaning brush's operation and improves the user's hand comfort. At the same time, after the torque is canceled out, the lateral force on the support body is greatly reduced, effectively preventing the brush head from deviating due to torque imbalance when a single brush head rotates. This ensures that the brush head can accurately align with the cleaning area, guaranteeing cleaning accuracy and avoiding cleaning omissions caused by deviation. In addition, in the transmission assembly, the drive gear, as the high-speed gear, is made of metal, which is high in strength, long in life, and resistant to high temperatures. The transition gear set and the output gear set are low-speed gear sets, made of plastic, which has the advantages of being lightweight, quiet, and shock-absorbing. The combination of metal gears and plastic gears can achieve the effect of reducing noise and vibration while meeting the transmission load.

[0020] III. Extend equipment lifespan and improve user comfort: Due to the reduced vibration amplitude, the vibration impact on components such as the support body, rotating power component, and transmission component is significantly reduced, decreasing the probability of wear and loosening between components and effectively extending the overall service life of the cleaning brush. Furthermore, the design of two brush heads rotating synchronously in opposite directions ensures more even force distribution during cleaning, preventing damage to individual brush heads due to excessive force and further improving brush head durability and overall user comfort. In addition, a contoured meshing tooth is introduced during the disassembly and assembly of the cleaning brush head. This tooth engages with the output gear without clearance, and the fully contacted curved surfaces between the meshing tooth and the output gear reduce contact stress on the output gear teeth, further minimizing damage to the output gear assembly during disassembly and assembly, and extending the equipment's service life.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] Example 1: This invention provides a dual-headed cleaning brush, see reference. Figures 1 to 18 As shown, the dual-headed cleaning brush includes a support body 1 and a cleaning brush device 2.

[0025] The cleaning brush device 2 is mounted on the support body 1. The cleaning brush device 2 includes a first brush head assembly 21, a second brush head assembly 22, a rotational power assembly 23, and a transmission assembly. The first brush head assembly 21 and the second brush head assembly 22 are independent of each other. Both the first brush head assembly 21 and the second brush head assembly 22 are connected to the rotational power assembly 23 through the transmission assembly. The rotational power assembly 23 provides rotational power to the first brush head assembly 21 and the second brush head assembly 22. The transmission assembly is used to transmit the rotational power to the first brush head assembly 21 and the second brush head assembly 22.

[0026] When in use, the rotary power component 23 is activated, which drives the first brush head component 21 and the second brush head component 22 to rotate synchronously in opposite directions through the transmission component, thereby cleaning the grilling mesh.

[0027] During the above process, the two brush head components that rotate synchronously in opposite directions cooperate with each other. On the one hand, they can expand the cleaning coverage area, improve cleaning efficiency and cleaning effect. On the other hand, they can effectively counteract the rotational torque, reduce vibration and deviation, and improve user comfort while extending the service life of the device.

[0028] Example 2: Example 2 is based on Example 1: like Figures 1 to 18 As shown, the rotary power assembly 23 is an electric power assembly, including a vertical motor.

[0029] The transmission assembly includes a drive gear 24, a transition gear set 25, a first output gear 26, and a second output gear 27.

[0030] The drive gear 24 is connected to the output end of the rotary power assembly 23; the first output gear 26 is connected to the drive gear 24 through the transition gear set 25, and the first brush head assembly 21 is coaxially arranged with the first output gear 26 and rotates synchronously; the second output gear 27 is connected to the drive gear 24 through the transition gear set 25, and the second brush head assembly 22 is coaxially arranged with the second output gear 27 and rotates synchronously.

[0031] Specifically, the transition gear set 25 includes a first reduction gear, a second reduction gear, a first transition gear, and a second transition gear. The upper large gear of the first reduction gear meshes with the drive gear 24, the lower small gear of the first reduction gear meshes with the lower large gear of the second reduction gear, the upper small gear of the second reduction gear meshes with the first transition gear, the first transition gear meshes with the first output gear 26, the second transition gear meshes with the first transition gear, and the second output gear 27 meshes with the second transition gear.

[0032] Furthermore, the drive gear 24 is a high-speed gear made of metal, which has high strength and long service life; the transition gear set 25, the first output gear 26, and the second output gear 27 are all low-speed gears made of plastic, which are lightweight and have advantages such as quietness and shock absorption.

[0033] The transmission component adopts a gear transmission component. Gear transmission has high transmission efficiency and smooth operation, which can ensure that the two brush heads rotate at the same speed and in opposite directions, thereby effectively offsetting the torque generated by the rotation of a single brush head, reducing the overall vibration of the cleaning brush, preventing deviation during operation, and improving handheld stability and cleaning accuracy.

[0034] As an optional implementation, the first output gear 26 is connected to the first connecting tray 28, and the second output gear 27 is connected to the second connecting tray 29. The first connecting tray 28 and the second connecting tray 29 are located at the bottom of the support head 11 of the support body 1. The first connecting tray 28 and the second connecting tray 29 are detachably connected to the first brush head assembly 21 and the second brush head assembly 22 respectively through corresponding rotating snap-fit ​​structures 211.

[0035] In practical applications, brush head assemblies come in various types, including fireproof brushes, wire brushes, nylon soft brushes, and scouring pad brush heads. They employ a detachable connection method, making it easy for users to replace them according to their actual needs.

[0036] As an optional implementation, the rotating snap-fit ​​structure 211 includes a limiting block 2111, a guide groove 2112, and a positioning groove 2113. The limiting block 2111 is integrally disposed on the connecting tray, and the guide groove 2112 and the positioning groove 2113 are integrally disposed on the brush head assembly. The starting end of the guide groove 2112 is provided with an opening for the limiting block 2111 to be inserted. The positioning groove 2113 is connected to the ending end of the guide groove 2112 and is adapted to the limiting block 2111.

[0037] During installation, align the limiting block 2111 with the starting end of the guide groove 2112, then move the brush head assembly so that the limiting block 2111 is inserted into the guide groove 2112 along the starting end. Then rotate the brush head assembly so that the limiting block 2111 rotates and slides into and engages with the positioning groove 2113.

[0038] The positioning groove 2113 is provided with a snap-fit ​​groove, and the limiting block 2111 is provided with a snap-fit ​​protrusion. When the limiting block 2111 is fully inserted into the positioning groove 2113, the snap-fit ​​protrusion snaps into the snap-fit ​​groove.

[0039] The rotating snap-fit ​​structure allows for quick assembly and disassembly of the brush head assembly, making replacement extremely convenient. After disassembly, the brush head can be thoroughly cleaned without any blind spots. Furthermore, when the brush head assembly is damaged, it can be replaced individually, effectively ensuring cost control.

[0040] As an optional implementation, the dual-head cleaning brush includes a locking device 3, which includes a press-type locking member 31. The press-type locking member 31 is movably inserted into the support body 1. The pressing end of the press-type locking member 31 is located outside the support body 1, and the locking end of the press-type locking member 31 is configured as a contour-fitting tooth 311, which is adapted to the output gear.

[0041] The push-type locking element 31 is positioned corresponding to either the first output gear 26 or the second output gear 27. By engaging with either of the aforementioned output gears via the conformal meshing teeth 311, the entire gear transmission structure can be locked.

[0042] Specifically, the contoured meshing gear 311 and the output gear have a fully mating curved surface contact, which can reduce the contact stress on the output gear tooth surface, reduce component damage, and extend service life.

[0043] When disassembling the brush head assembly, press the push-type locking piece 31 to make the contour mating teeth 311 engage with the first output gear 26. At this time, the entire gear transmission structure is locked, and both the first output gear 26 and the second output gear 27 are locked and cannot be rotated. Then, the user can rotate the first brush head assembly 21 and the second brush head assembly 22 respectively to disassemble the brush head assembly.

[0044] The push-type locking element 31 is designed to both restrict the rotation of the brush head assembly, thus facilitating the replacement of the brush head assembly, and to lock it by pressing, making operation convenient.

[0045] As an optional implementation, the dual-head cleaning brush includes a lighting device 4, which includes an LED illumination module 41, and the LED illumination module 41 is fixedly mounted on the support body 1.

[0046] Specifically, the LED spotlight module 41 is installed inside the support body 1, corresponding to the front end of its handle 12. The front end of the handle 12 is provided with a lampshade 42, which covers the outside of the LED spotlight module 41.

[0047] As an optional implementation, the dual-head cleaning brush includes a water washing device 5, which includes a water tank 51, a water spray nozzle assembly 52, and a water spray power assembly 53.

[0048] The water tank 51 is installed on the support body 1. Specifically, the water tank 51 is located inside the support head 11 of the support body 1, and its shape is adapted to the inner cavity shape of the support head 11.

[0049] The nozzle assembly 52 is located between the first brush head assembly 21 and the second brush head assembly 22. The nozzle assembly 52 is connected to the water tank 51 through a water supply pipe. The nozzle assembly 52 is located at the front end of the bottom side of the support head 11.

[0050] The water jet power unit 53 uses a water pump, which is installed on the water supply pipeline.

[0051] When cleaning the baking pan, the water spray power unit 53 operates, transporting the cleaning water in the water tank 51 to the water spray nozzle assembly 52 through the delivery pipeline, and the water spray nozzle assembly 52 sprays the water onto the baking pan.

[0052] In actual use, the spray nozzle assembly 52 wets the baking mesh, which can adsorb solid microparticles, reduce dust, and combine water washing with rotating brush washing to effectively improve the cleaning effect of stubborn stains, reduce repeated manual wiping, and improve cleaning efficiency.

[0053] The water spray nozzle assembly 52 is arranged between the two brush heads, allowing the water flow to directly act on the cleaning area, making more rational use of water resources.

[0054] As an optional implementation, the spray nozzle assembly 52 includes a spray nozzle 521 and a dispersing disc 522. The spray nozzle 521 is fixedly mounted on the support head 11, and the top inlet of the spray nozzle 521 is connected to the outlet of the water supply pipeline. The dispersing disc 522 is located at the bottom outlet of the spray nozzle 521, and the dispersing disc 522 has a plurality of dispersing outlets 5221 arranged circumferentially.

[0055] This setup creates a surface spray, expanding the water coverage area and allowing the water flow to act more evenly on the surface of the grill and the gaps in the mesh, thus improving the washing effect.

[0056] As an optional implementation, the dual-head cleaning brush includes a mudguard device 6, which is located at the rear end of the support head 11.

[0057] The mudguard device 6 includes a support plate 61, a splash mudguard 62, and an elastic element 63. The support plate 61 is fixedly installed inside the support head 11 and located at the rear end. The top side of the splash mudguard 62 is rotatably connected to the support plate 61 through a hinge shaft. The elastic element 63 is a torsion spring, sleeved on the hinge shaft, and its two ends abut against the support plate 61 and the splash mudguard 62, respectively.

[0058] During the cleaning process of the grilling mesh, the splash guard 62 can rotate around the hinge axis and adaptively adhere to the surface of the grilling mesh under the action of the elastic element 63, which not only ensures the splash prevention effect, but also does not affect the normal cleaning movement of the brush head. The structure is simple and highly adaptable.

[0059] As an optional implementation, the dual-head cleaning brush includes an electronic control device 7, which includes a power supply 71, a control board 72, and control buttons 73. The control board 72 is electrically connected to the power supply 71. The control buttons 73 are located on the control board 72. The rotating power assembly 23, the LED illumination module 41, and the water spraying power assembly 53 are all electrically connected to the control board 72.

[0060] In practical applications, users can easily switch working modes, start and stop cleaning and water spraying functions through control button 73. The operation is simple and intuitive, improving the automation level and ease of use of the product.

[0061] As an optional implementation, the support body 1 includes a handle 12 and a support head 11. The support head 11 is disposed at the front end of the handle 12. The cleaning brush device 2, the water washing device 5 and the mudguard device 6 are disposed on the support head 11, and the electronic control device 7 is disposed on the handle 12.

[0062] In actual use, users can perform cleaning operations simply by holding the handle 12.
