Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a direct-drive barbecue grill cleaning device. Background Technology

[0002] Barbecue is a popular cooking method, but the subsequent cleaning, especially of the grill grill grates, has always been a tedious and laborious task. To address this need, various electric cleaning devices have emerged on the market.

[0003] Currently, most electric barbecue grill cleaning brushes on the market use a single motor with a gear transmission system. This means a single motor provides power, which is then transmitted to the brush head via a set of gears (such as planetary gears or reduction gears). The advantage of this structure is its relative simplicity and low cost. However, in actual use, this traditional structure reveals significant drawbacks: Gear transmission structures, especially plastic gears, need to withstand large torque and impact loads when cleaning high-strength barbecue grills, which can easily lead to gear shaving, wear, and breakage, resulting in a significant shortening of product life.

[0004] The design of a single motor driving a single brush head or a linked brush head often results in insufficient cleaning efficiency and coverage area. For stubborn barbecue grime, users need to clean it repeatedly, which is time-consuming and laborious.

[0005] Most existing products have a high degree of integrated design, and the brush head is a vulnerable part. When it is worn out, it is difficult to replace quickly, or the replacement process is cumbersome, resulting in a poor user experience.

[0006] The cleaning process is usually carried out in environments with poor visibility, and most existing equipment lacks auxiliary lighting, making it difficult for users to see whether the stains in the gaps of the grid have been completely removed, thus affecting the cleaning effect.

[0007] In addition, during the cleaning process, oil stains and food residues can easily splatter, contaminating users or the cleaning environment, and existing designs lack effective protective measures against this. Utility Model Content

[0008] The technical problem to be solved by this utility model is a direct-drive barbecue oven cleaning device, which can effectively solve the shortcomings of the existing technology.

[0009] This utility model is achieved through the following technical solution: a direct-drive barbecue grill cleaning device, comprising: A housing, one end of which is provided with a hand-held handle; A fixed box and a movable box are disposed on the bottom sides of the housing. The fixed box is fixedly installed to the housing, and one side of the movable box is hinged to the housing. At least two cleaning devices are disposed between the movable box and the fixed box, one end of the cleaning device is fixedly connected to the movable box, and the other end of the cleaning device is positioned and connected to the fixed box; An elastic squeezing mechanism is disposed inside the fixed box. Pressing the elastic squeezing mechanism separates the cleaning device from the fixed box, allowing the cleaning device to be opened outward through the movable box.

[0010] As a preferred technical solution, each of the cleaning devices includes a motor, one end of which is fixedly installed in the fixed cavity inside the movable box. A shaft sleeve is installed at the output end of the motor, and a cleaning brush is fitted on the outside of the shaft sleeve. The end of the cleaning brush away from the shaft sleeve is positioned and assembled with a positioning head on the fixed box.

[0011] As a preferred technical solution, one end of the movable box opens with the hinge seat on the housing.

[0012] As a preferred technical solution, a floating plate is provided inside the fixed box, the positioning head is provided on the floating plate, a positioning bushing is provided on the inner end of the positioning head, a spring is fitted on the positioning bushing, one end of the spring is positioned with the positioning head, and the other end is positioned and supported with the fixed seat, and the floating plate is pushed out by the spring.

[0013] As a preferred technical solution, a light is provided at the front end of the housing, a control main board is provided inside the housing located inside the light, the control main board is connected to the light, a plurality of control buttons are provided on the handle for control, and the power control terminal of the cleaning device is connected to the control main board.

[0014] As a preferred technical solution, a power source is also provided inside the housing to supply power to the cleaning device and the lighting lamp.

[0016] As a preferred technical solution, the control motherboard is also provided with a charging interface for supplying power to the power source.

[0017] The beneficial effects of this utility model are as follows: This utility model abandons the traditional gear transmission mechanism and adopts a dual-motor direct drive method, that is, each cleaning brush is directly driven by an independent motor through a shaft sleeve. This structure completely eliminates the failure problems caused by gear overload, tooth shaving, and wear, resulting in higher transmission efficiency, stronger load capacity, and significantly improved product durability and service life; This invention provides stronger power and a larger cleaning coverage area by setting up a double-row cleaning brush driven directly by two motors. The dual brushes work together to remove stubborn grease and carbonized residue from barbecue grills more quickly and effectively, greatly improving cleaning efficiency and effectiveness. This utility model, through the structure of the movable box and the elastic squeezing mechanism, allows the user to separate the cleaning device from the fixed box simply by pressing the elastic squeezing mechanism, and easily flip open the movable box along with the brush head, achieving quick disassembly and installation of the brush head. This ingenious structure is simple to operate and greatly facilitates the replacement and cleaning of the brush head and the maintenance of the equipment. This utility model integrates a lighting lamp and a control motherboard inside the housing, enabling users to clearly illuminate the gaps in the grill grill when cleaning in low-light environments, accurately judge the cleaning status, ensure no blind spots in cleaning, and improve the practicality of the product and user experience. The baffle provided by this invention at the end of the housing near the handle can effectively block oil and food residue splashed from the brush head during the cleaning process, preventing pollution of the user or the surrounding environment and making the cleaning process safer and more hygienic.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figures 1-4 As shown, the present invention discloses a direct-drive barbecue grill cleaning device, the specific implementation of which is as follows: The device mainly includes a housing 3, which is typically made of heat-resistant and insulating engineering plastic. One end of the housing 3 is provided with an ergonomic handheld handle 1 for easy gripping and operation by the user. A fixed box 9 and a movable box 7 are provided on both sides of the bottom of the housing 3. The fixed box 9 is fixedly installed to the housing 3 by screws or clips, while one side of the movable box 7 is hinged to a hinge seat 6 on the housing 3 via a pivot or hinge, allowing the movable box 7 to open, close, and rotate relative to the housing 3.

[0023] At least two cleaning devices 5 are arranged between the movable box 7 and the fixed box 9. Each cleaning device 5 includes a motor 53, preferably a DC geared motor, whose body is fastened to a pre-set fixed cavity inside the movable box 7 by screws to ensure a secure installation. A shaft sleeve 52 made of metal or high-strength plastic is directly installed at the output end of the motor 53. The shaft sleeve 52 is fitted and fixed to the external cylindrical cleaning brush 51 by an interference fit or keyway. The cleaning brush 51 is usually made of metal wire or high-temperature resistant bristles. Its end away from the shaft sleeve 52 is detachably positioned and assembled with the positioning head 91 on the fixed box 9 by a snap-fit ​​structure or magnetic adsorption. This dual-motor independent direct drive design eliminates the traditional gear transmission mechanism. The motor 53 directly drives the shaft sleeve 52 and the cleaning brush 51 to rotate at high speed, which not only has high transmission efficiency and low power loss, but also fundamentally avoids failures such as gear system overload, gear sweeping and wear, greatly improving the reliability and service life of the device. The dual-row cleaning brush layout provides greater cleaning coverage and stronger cleaning power, effectively removing stubborn dirt from barbecue grills.

[0024] To facilitate quick brush head replacement and maintenance, a spring-loaded compression mechanism is installed inside the mounting box 9. This mechanism comprises a movable floating plate 92, on which the positioning head 91 of the mounting box 9 is mounted. A guide positioning sleeve 93 is located on the inner end of the positioning head 91, and a spring 94 is fitted onto the positioning sleeve 93. One end of the spring 94 rests against the positioning head 91, while the other end is supported by a mounting base on the inner wall of the mounting box 9. In its natural state, the spring force of the spring 94 pushes the floating plate 92 and the positioning head 91 outwards through the positioning sleeve 93, thus stably holding the end of the cleaning brush 51 within the positioning head 91. When the user needs to replace the brush head, they simply press the floating plate 92 or the positioning head 91 inwards (the pressing action can be achieved via a button on the housing 3 or by directly pushing the floating plate 92), overcoming the spring force of the spring 94, causing the positioning head 91 to retract inwards, thereby releasing the lock on the end of the cleaning brush 51. At this point, since the other end of the cleaning brush 51 remains fixed to the output end of the motor 53 of the movable box 7, the user can easily flip the hinged movable box 7 outwards, exposing both cleaning brushes 51 along with the movable box 7, facilitating the disassembly, cleaning, or replacement of the brush heads. The entire operation is simple and quick, greatly improving the maintainability of the equipment.

[0025] An integrated light 4, such as an LED bulb, is mounted on the front of the housing 3, and can be protected by a transparent lampshade. A control board is located inside the housing 3, behind the light 4. This board is connected via wires to the light 4, multiple control buttons 2 on the handle 1, and the power control terminals of the motors 53 of the two cleaning devices 5. The housing 3 typically also houses a rechargeable lithium battery, which powers the motors 53, light 4, and control board via wires. The control board can also be equipped with a USB Type-C or Micro-USB charging port for connecting an external power source to charge the built-in battery. The lighting function allows users to clearly illuminate the grill crevices when cleaning the grill at night or in dimly lit areas, accurately assessing the cleaning effect without any blind spots.

[0026] In addition, a baffle 8 is provided above the end of the housing 3 near the handle 1. The baffle 8 can be made of metal or plastic, and its shape is usually adapted to the rotation trajectory of the cleaning brush 51. During the cleaning process, the baffle 8 can effectively block dirt such as oil, carbon residue, and water droplets that are flung up by the rotating brush head, preventing them from splashing onto the user or polluting the surrounding environment, making the cleaning process safer and more hygienic.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
