Description

Technical Field

[0001] This utility model relates to the field of barbecue equipment cleaning technology, specifically to a cleaning device for cleaning barbecue grills. This device can efficiently remove various types of deposits on the barbecue grill, improving cleaning efficiency and effectiveness. Background Technology

[0002] Barbecue, as a popular cooking and social activity, boasts a large consumer base worldwide. Whether for family gatherings, outdoor picnics, or commercial barbecues, barbecue grills are indispensable. However, grease and food residue produced during grilling adhere to the grill's surface, affecting its lifespan and potentially breeding bacteria, posing a threat to food safety. Therefore, cleaning barbecue grills is crucial.

[0003] Traditional methods of cleaning barbecue grills mainly rely on manual labor, using brushes, detergents, and other tools to wipe and scrub. This method has several problems:

[0004] Manual cleaning is time-consuming and labor-intensive, especially for large commercial barbecue grills, where cleaning can take hours or even longer, severely impacting the operational efficiency of barbecue venues. For example, after a large barbecue restaurant closes for the day, staff may need to spend several hours cleaning the grills, which not only increases labor costs but also prevents the restaurant from preparing for the next round of preparations in a timely manner.

[0005] Manual cleaning often fails to completely remove stubborn grease and food residue from barbecue grills, especially grime in crevices and corners. Over time, this grime becomes increasingly difficult to remove, affecting the grill's performance and lifespan. For example, food residue often remains in the gaps of the grill's mesh, which is difficult to remove completely by hand. This residue carbonizes at high temperatures, further increasing the difficulty of cleaning.

[0006] During manual cleaning, workers need to frequently bend over and wipe vigorously, which can easily lead to physical fatigue and injury. This is especially true when cleaning large barbecue grills, where workers need to maintain the same posture for extended periods, putting significant pressure on their lower back, arms, and other areas. For example, cleaning large outdoor barbecue grills requires workers to climb up and down, constantly adjusting their posture, making the work extremely strenuous.

[0007] To improve cleaning effectiveness, people often use various cleaning agents. However, if the wrong cleaning agent is chosen or used in excess, it may corrode the grill, affecting its performance and safety. Furthermore, cleaning agent residue can contaminate food and harm human health. For example, some highly alkaline cleaning agents, if not rinsed off completely, will leave marks on the grill surface and may react with food during the next use.

[0008] With the development of technology, some equipment for cleaning barbecue grills has appeared on the market. However, most of these devices have limitations. Some cleaning equipment uses complex mechanical structures and control systems, resulting in high prices and maintenance costs. For small barbecue restaurants or home users, such costs are unaffordable. For example, some large-scale cleaning equipment using automated control can cost tens of thousands of yuan, and repair and maintenance costs are also very high.

[0009] In conclusion, existing barbecue grill cleaning methods and equipment have certain shortcomings and cannot meet the market's demand for efficient, convenient, and environmentally friendly barbecue grill cleaning. Therefore, developing a new type of cleaning equipment for barbecue grills is of significant practical importance. Utility Model Content

[0010] To address the aforementioned problems in the prior art, this utility model proposes a cleaning device for cleaning barbecue grills. This device is characterized by its simple structure, convenient operation, high cleaning efficiency, and environmental friendliness.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] A cleaning device for cleaning barbecue grills includes a grippable housing and a drive mechanism attached to the housing. The drive mechanism includes a motor, an eccentric cam, and a vibration transmission rod. The motor is configured to output rotational power. The eccentric cam has a circumferentially formed cam surface and is configured to receive the rotational power from the motor and rotate eccentrically about an axis. The vibration transmission rod has an actuation portion at its base end that extracts the rotational power. The actuation portion is movably connected to the cam surface of the eccentric cam, converting the extracted rotational power into reciprocating movement at its front end. A cleaning brush is attached to the front end, and when the motor rotates, the cleaning brush follows the vibration transmission rod in reciprocating movement to remove residue from the barbecue grill.

[0013] Furthermore, the actuating part is configured as an annular fitting part, which slides freely into the cam surface of the eccentric cam. The annular fitting part and the eccentric cam can be fitted together via rolling bearings or wear-resistant sleeves to reduce friction and wear. To prevent jamming between the annular fitting part and the eccentric cam, the annular fitting part has a clearance space in a first direction perpendicular to the vibration transmission rod, or a movable joint is provided in the middle of the vibration transmission rod.

[0014] Furthermore, the motor is connected to the eccentric cam via a transmission mechanism, which includes a pair of meshing spur gears and a crown gear. The eccentric cam is fixed to the crown gear, and the central axis of the eccentric cam is offset from the rotation axis of the crown gear to achieve eccentric rotation. The spur gear is fixed to the motor shaft. The eccentric cam and crown gear can be integrally formed, with the central axis of the motor shaft parallel to the axis of the vibration transmission rod to simplify the transmission structure.

[0015] Furthermore, the front end of the vibration transmission rod has a mounting head, on which the cleaning brush is detachably attached, facilitating the replacement of cleaning brushes of different specifications or materials to meet different cleaning needs. The front end of the housing has a through hole for the vibration transmission rod to pass through, and a sliding bearing that slides with the vibration transmission rod is fixed in the through hole. At least two sliding bearings are configured to improve the sliding stability and durability of the vibration transmission rod.

[0016] Furthermore, the vibration transmission rod has a first limit position and a second limit position. When the eccentric cam rotates, the vibration transmission rod reciprocates between the first limit position and the second limit position. When the vibration transmission rod is at the first limit position, the cleaning brush moves away from the housing; when the vibration transmission rod is at the second limit position, the cleaning brush moves closer to the housing, thereby realizing the reciprocating vibration cleaning action of the cleaning brush.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] 1. Vibration cleaning removes residue from the grill more quickly than traditional manual cleaning, improving cleaning efficiency. 2. Automated cleaning reduces manual operation, lowers the workload for staff, and increases work efficiency. 3. It eliminates the need for large amounts of cleaning agents, reducing the corrosive effects of chemical cleaners on the environment and the grill, while also lowering cleaning costs. 4. The motor features an energy-saving design, reducing energy consumption. 5. Modular design makes disassembly, assembly, and maintenance of the equipment more convenient, reducing maintenance costs.

[0019] In summary, the cleaning equipment for cleaning barbecue grills of this invention has the characteristics of simple structure, convenient operation, high cleaning efficiency and environmental protection. It can meet the market demand for efficient, convenient and environmentally friendly barbecue grill cleaning and has broad market application prospects and practical value.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0035] Example 1:

[0036] like Figures 1-5As shown, the cleaning device for cleaning barbecue grills of this utility model mainly includes a housing 1, a drive unit 2, a vibration transmission rod 3, and a cleaning brush 4. The housing 1 serves as the support and protective structure for the entire device and has a handle for easy user operation. The drive unit 2 is attached to the housing 1 and provides the power source for the device. The vibration transmission rod 3 is connected to the drive unit 2, converting rotational power into reciprocating motion, thereby driving the cleaning brush 4 to perform the cleaning action.

[0037] like Figures 3-4 As shown, the drive device 2 is the core component of this invention. It is responsible for converting electrical energy into mechanical energy to drive the cleaning brush 4 to perform vibration cleaning. The drive device 2 includes a motor 21, an eccentric cam 22, a transmission mechanism 23, and a fixing structure. The motor 21 is fixed inside the housing through this fixing structure. The motor 21 is attached to the housing 1 through the fixing structure to ensure its stability and reliability during operation. In this embodiment, the fixing structure can be implemented using bolts, clips, screws, etc. To improve the fixing effect, the fixing structure can also be provided with positioning pins or positioning holes to ensure that the installation position of the motor 21 inside the housing 1 is accurate. In addition, the fixing structure can also adopt a detachable design to facilitate user maintenance and replacement of the drive device 2.

[0038] Motor 21 is the power source for drive device 2, and its type can be selected according to the usage requirements and power requirements of the equipment. In this embodiment, a DC motor is preferred because DC motors have advantages such as a wide speed range and convenient control. Motor 21 is connected to a power source via wires, which can be a battery, AC power, or power adapter. To improve the portability and flexibility of the equipment, the power source in this embodiment is preferably a rechargeable battery, such as a lithium battery or a nickel-metal hydride battery.

[0039] A spur gear 231 is fixedly connected to the shaft end of motor 21. The number of teeth on spur gear 231 matches the number of teeth on crown gear 232 to ensure a reasonable transmission ratio and achieve efficient power transmission. To improve heat dissipation and prevent overheating of the motor and battery during use, a fan and cooling ducts can be further installed inside the housing for air cooling of the battery and motor. When motor 21 is working, the fan starts simultaneously, drawing air into the housing and blowing it onto motor 21 and battery through the cooling ducts, carrying away the heat generated and ensuring the safe and stable operation of the equipment.

[0040] The eccentric cam 22 is a key component in the drive unit 2, responsible for converting the rotational power of the motor into the reciprocating movement of the vibration transmission rod 3. The eccentric cam 22 has a cam surface formed circumferentially, which is movably connected to the actuating part (i.e., the annular fitting part 31) of the vibration transmission rod 3. The central axis of the eccentric cam 22 is offset from its rotational axis, causing the eccentric cam 22 to rotate eccentrically around its rotational axis under the drive of the motor 21. This causes the annular fitting part 31 to slide on the cam surface, thus realizing the conversion of rotational power into reciprocating movement.

[0041] To improve the wear resistance and service life of the eccentric cam 22, its material can be selected from high-strength, wear-resistant plastic materials, or even metal materials.

[0042] The transmission mechanism 23 is responsible for transmitting the rotational power of the motor 21 to the eccentric cam 22. In this embodiment, the transmission mechanism 23 includes a pair of meshing spur gears 231 and crown gears 232. The spur gear 231 is fixed to the motor shaft, and the crown gear 232 is fixed to the eccentric cam 22 (the eccentric cam 22 and crown gear 232 can be integrally set to improve the compactness and stability of the structure). When the motor 21 rotates, the spur gear 231 drives the crown gear 232 to rotate, which in turn drives the eccentric cam 22 to rotate eccentrically.

[0043] To improve transmission efficiency, the tooth profile and pitch of spur gear 231 and crown gear 232 are carefully designed to ensure smooth meshing and low noise. In addition, the transmission mechanism 23 can also be equipped with lubrication structures (not shown in the figure), such as oil grooves and oil holes, to periodically add lubricant to the gear set, reducing wear and noise. The lubricant can be grease or lubricating oil, depending on the operating environment and temperature conditions.

[0044] The vibration transmission rod 3 is a key component connecting the drive device 2 and the cleaning brush 4. It is responsible for converting the rotational power of the drive device 2 into the reciprocating movement of the cleaning brush 4. The vibration transmission rod 3 includes an actuating part (i.e., an annular fitting part 31) on the base side and a mounting head 33 on the front end side.

[0045] The annular fitting part 31 is the connecting component between the vibration transmission rod 3 and the eccentric cam 22, and it slides freely into the cam surface of the eccentric cam 22. The inner wall of the annular fitting part 31 is in close contact with the cam surface to ensure the efficiency and stability of power transmission. To reduce friction and wear, the annular fitting part 31 and the eccentric cam 22 can be fitted together via rolling bearings or wear-resistant sleeves. Rolling bearings have good load-bearing capacity and wear resistance, which can reduce friction and wear; wear-resistant sleeves have advantages such as low cost and easy installation. The selection of rolling bearings or wear-resistant sleeves can be determined according to actual usage and cost considerations. In this embodiment, the annular fitting part 31 and the eccentric cam 22 can be fitted together via wear-resistant sleeve 221.

[0046] Furthermore, to prevent jamming between the annular fitting part 31 and the eccentric cam 22, the annular fitting part 31 has a clearance space in a first direction perpendicular to the vibration transmission rod 3. The clearance space design allows the annular fitting part 31 to slide more smoothly on the cam surface, reducing jamming and wear.

[0047] like Figure 5 As shown, in another embodiment without a clearance space, the movable joint 32 is an optional component of the vibration transmission rod 3, allowing the vibration transmission rod 3 to bend or twist to a certain extent during its reciprocating movement. The movable joint 32 is provided on the vibration transmission rod 3 to increase its flexibility and adaptability. Especially when cleaning complex or hard-to-reach areas of the grill, the movable joint 32 allows the vibration transmission rod 3 to bend or twist within a certain range, ensuring that the cleaning brush 4 can closely adhere to the grill surface and improve cleaning effectiveness. The design of the movable joint 32 can accommodate the sliding trajectory of the annular fitting 31 on the cam surface, preventing jamming and wear caused by trajectory changes. The movable joint 32 can adopt a hinge structure, a ball joint structure, or other flexible and torsionible structural forms.

[0048] In the embodiment described above where no clearance space is provided, the movable joint 32 is mounted on the vibration transmission rod 3 to ensure that it can effectively adapt to changes in the sliding trajectory of the annular fitting portion 31. Simultaneously, the movable joint 32 also provides a certain buffering effect, reducing impact and noise during vibration transmission.

[0049] like Figures 1-2 As shown, the mounting head 33 is the front end component of the vibration transmission rod 3, and it is responsible for connecting the cleaning brush 4. The design of the mounting head 33 can be customized according to the shape and connection method of the cleaning brush 4. In this embodiment, the mounting head 33 is connected to the cleaning brush 4 by a snap-fit ​​method, which makes it convenient for users to replace the cleaning brush 4 with different specifications or materials to meet different cleaning needs.

[0050] Mounting head 33 is the connecting component between vibration transmission rod 3 and cleaning brush 4, responsible for transmitting the reciprocating movement of vibration transmission rod 3 to cleaning brush 4. The shape and size of mounting head 33 can be designed according to the specific type and installation method of cleaning brush 4. For example, when cleaning brush 4 is bristle type, mounting head 33 can be designed as a cylindrical or flat structure with bristle base, which is fixed to mounting head 33 by threaded connection, snap-fit ​​connection or adhesive. When cleaning brush 4 is cloth pad type or sponge type, mounting head 33 can be designed as a structure with clamping groove or Velcro to firmly fix cleaning brush 4 to the front end of vibration transmission rod 3.

[0051] To accommodate grills of different shapes and sizes, the shape and size of the cleaning brush 4 can also be customized. For example, for flat grills, a flat-shaped cleaning brush 4 can be selected; for mesh grills, a cleaning brush 4 with curved or hooked bristles can be selected to better remove dirt from the mesh gaps.

[0052] To improve the connection stability and cleaning effect between the mounting head 33 and the cleaning brush 4, an anti-slip structure or a material that increases friction can be provided on the surface of the mounting head 33. For example, raised dots, grooves, or roughening treatments can be applied to the surface of the mounting head 33 to increase the friction between it and the cleaning brush 4, preventing it from slipping or loosening during the cleaning process.

[0053] Furthermore, to improve the durability and stability of the mounting head 33, it can be made of a high-strength, wear-resistant material. Additionally, the surface of the mounting head 33 can be treated with an anti-slip coating to ensure the stability and reliability of the cleaning brush 4 during connection.

[0054] The cleaning brush 4 is a cleaning component that directly applies cleaning to the surface of the barbecue grill. Its material and shape are selected according to cleaning needs. In this embodiment, the bristles of the cleaning brush 4 can be made of materials such as nylon, steel wire, or copper wire, and the length and density of the bristles can also be adjusted according to the cleaning effect.

[0055] In addition, to improve the durability and stability of the cleaning brush 4, its bristles can undergo special treatments such as carbonization, heat treatment, or surface hardening. These treatments can increase the hardness and wear resistance of the bristles, extending their service life.

[0056] The housing 1 serves as the support and protective structure for the entire device, and features a handle for easy gripping and operation. The housing 1 can be made of high-strength plastic, aluminum alloy, or stainless steel to ensure sufficient rigidity and strength.

[0057] The front end of the housing 1 has a through hole 11 for the vibration transmission rod 3 to pass through, and a sliding bearing 12 that slides with the vibration transmission rod 3 is fixedly connected in the through hole 11. At least two sliding bearings 12 are configured to improve the sliding stability and durability of the vibration transmission rod 3. The sliding bearings 12 can be made of a wear-resistant material, such as bearing steel.

[0058] To improve the sealing and waterproofing of the housing 1, a sealing gasket or sealing ring (not shown in the figure) can also be provided around the through hole 11. The selection of the sealing gasket or sealing ring can be determined based on actual usage and cost considerations.

[0059] In addition, the housing 1 can also be equipped with a switch button for controlling the start and stop of the motor 21. The switch button can be located on the handle or side of the housing 1 for easy user operation. To improve the safety of the equipment, the switch button can also be equipped with a waterproof and dustproof structure to prevent poor contact or short circuits caused by moisture or dust.

[0060] Working principle and operating instructions:

[0061] In operation, the cleaning device for cleaning barbecue grills of this invention is first used by the user to hold the handle on the housing 1 and bring the device close to the area of ​​the barbecue grill to be cleaned. Then, the power is turned on, and the motor 21 begins to rotate, transmitting the rotational power to the eccentric cam 22 via the transmission mechanism 23. The eccentric rotation of the eccentric cam 22 causes the annular fitting part 31 to slide on the cam surface, thereby realizing the reciprocating movement of the vibration transmission rod 3. Finally, this reciprocating movement is transmitted to the cleaning brush 4 through the mounting head 33, causing it to vibrate and clean the surface of the barbecue grill.

[0062] During operation, users can adjust the angle and position of the device according to their cleaning needs and the specific structure of the grill to ensure that the cleaning brush 4 can fully and evenly cover the entire area to be cleaned. Simultaneously, users can also change the vibration frequency and intensity of the cleaning brush 4 by controlling the power switch or adjusting the motor speed to adapt to grills of different materials and levels of contamination.

[0063] Example 2:

[0064] The following differences are observed compared to Example 1:

[0065] like Figures 6-7 As shown, in this embodiment, the eccentric cam 22 abuts against the vibration transmission rod 3. A spring 34 is provided at the end of the vibration transmission rod 3 that contacts the eccentric cam 22. When the eccentric cam 22 rotates, its eccentricity causes the cam surface to periodically contact and push the vibration transmission rod 3. This process causes the vibration transmission rod 3 to move forward until it reaches the first limit position. During this movement, the spring 34, as an elastic energy storage element, is gradually compressed by the pushing action of the eccentric cam 22, storing the corresponding elastic potential energy.

[0066] As the eccentric cam 22 continues to rotate, its profile gradually moves away from the vibration transmission rod 3. At this point, the spring 34 releases its previously stored elastic potential energy, applying a reverse restoring force to the vibration transmission rod 3. This force drives the vibration transmission rod 3 to move in the opposite direction (i.e., backward) until it reaches the second limit position. In this way, the synergistic effect of the spring 34 and the eccentric cam 22 forms a dynamic balance, enabling the vibration transmission rod 3 to achieve continuous and stable reciprocating motion in the forward and backward directions.

[0067] 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 variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model 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 of the claims.
