Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to a barbecue grill cleaning device. Background Technology

[0002] Residual grease and food scraps can produce rancid and burnt smells. When you grill milder foods like fish, chicken, or vegetables, these odors can severely affect the pure flavor of the new food, making everything taste the same. Therefore, it is necessary to clean the grill.

[0003] However, current cleaning devices have a simple structure, and the contact area between the cleaning brush head and the grill is small. They cannot cross the vertical bars on the grill and are prone to getting stuck. Furthermore, replacing the cleaning brush head is relatively troublesome and cannot effectively clean surface impurities. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a barbecue grill cleaning device, which uses a ring-shaped cleaning brush head that can span the longitudinal bar, reducing the probability of jamming and facilitating the replacement of the cleaning brush head, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a barbecue grill cleaning device, including a motor fixing sleeve installed inside the outer shell, multiple fixing brackets installed on the outer ring of the motor fixing sleeve, a first helical gear is provided inside the fixing bracket, the two ends of the first helical gear protrude to form a shaft, a central shaft is installed on the shaft at one end of the first helical gear by a clamping shaft component, a cleaning brush head is sleeved on the outside of the central shaft, and a fixing component for pressing and positioning the cleaning brush head is threaded to the end of the central shaft away from the shaft. A motor is installed in the motor fixing sleeve, and a second helical gear is installed on the rotating shaft of the motor, and the second helical gear meshes with the first helical gear.

[0006] As a preferred technical solution, the clamping shaft components all include insert shafts and arc-shaped clamps. The end of the central shaft away from the fixed frame expands outward to form a connecting sleeve. The connecting sleeves are all fitted onto the shaft on one side. The connecting sleeves and the shaft on one side are both vertically provided with communicating positioning holes. The arc-shaped clamps are all fitted onto the outside of the connecting part and are elastically pressed against the connecting part. The insert shafts are all installed on the inner side of the arc-shaped clamps, and the other end of the insert shafts is all set through the positioning holes.

[0007] As a preferred technical solution, the fixing frame is divided into two parts, consisting of an upper frame and a lower frame. The upper frame and the lower frame are fixed together by screws. The opposite surfaces of the upper frame and the lower frame are provided with arc-shaped grooves. The upper and lower arc-shaped grooves are combined to form mounting holes. Bearings are installed in the mounting holes. The shafts at both ends of the first helical gear are inserted into the inner rings of the bearings.

[0008] As a preferred technical solution, multiple positioning plates are installed on both sides of the connecting sleeve, and multiple positioning grooves are provided at one end of the cleaning brush head, with the positioning plates inserted into the positioning grooves.

[0009] As a preferred technical solution, the interior of the casing also contains a mainboard that is electrically connected to the motor.

[0010] As a preferred technical solution, the shafts on one side of the first helical gear are provided with a first parallel surface, and the inner wall on one side of the connecting sleeve is provided with a second parallel surface, and the second parallel surface is fitted to the first parallel surface.

[0011] The beneficial effects of this utility model are: the utility model has a simple structure, the adjacent cleaning brush heads form an angle greater than zero degrees, ensuring that the movement direction of each rotatable cleaning brush head is different, and the multiple cleaning brush heads are distributed in a ring structure, which can cross the longitudinal bar on the barbecue grill, reducing the probability of jamming. In addition, the cleaning brush head is equipped with several bristles that extend radially from the rotating shaft. These bristles are made of high temperature resistant materials, which can quickly clean the surface after the barbecue grill is used, and can also extend into the side to ensure the cleaning effect. Furthermore, the central shaft and cleaning brush head can be quickly replaced by fixing parts and clamping rotating shaft parts.

[0012] In addition, this invention sets two cleaning brush heads coaxially, enabling the entire device to automatically move forward for cleaning.

[0013] This invention uses a motor to drive three gears to rotate the brush, thereby saving costs while achieving a cleaning effect and simplifying the structure. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] 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.

[0024] 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.

[0025] Example 1:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a barbecue grill cleaning device of this utility model includes a motor fixing sleeve 1 installed inside the outer shell. Multiple fixing brackets are installed on the outer ring of the motor fixing sleeve 1. Each fixing bracket is provided with a first helical gear 4 inside. Both ends of the first helical gear 4 protrude to form a shaft 13. A central shaft 12 is installed on the shaft 13 at one end of the first helical gear 4 by a clamping shaft component. A cleaning brush head 5 is sleeved on the outside of the central shaft 12. The end of the central shaft 12 away from the shaft 13 is threadedly connected to a fixing component 8 for pressing and positioning the cleaning brush head 5. A motor 9 is installed in the motor fixing sleeve 1. A second helical gear 11 is installed on the shaft of the motor 9. The second helical gear 11 is meshed with the first helical gear 4.

[0027] In this embodiment, each clamping shaft component includes an insert shaft 10 and an arc-shaped clamp 7. The end of the central shaft 12 away from the fixed frame expands outward to form a connecting sleeve 6. The connecting sleeve 6 is sleeved on the shaft 13 on one side. The connecting sleeve 6 and the shaft 13 on one side are vertically provided with a communicating positioning hole. The arc-shaped clamp 7 is sleeved on the outside of the connecting part and is elastically pressed against the connecting part. The insert shaft 10 is installed on the inner side of the arc-shaped clamp 7, and the other end of the insert shaft 10 passes through the positioning hole.

[0028] In this embodiment, the fixing frame is divided into two parts, consisting of an upper frame 2 and a lower frame 3. The upper frame 2 and the lower frame 3 are fixed together by screws. The upper frame 2 and the lower frame 3 are provided with arc-shaped grooves on their opposite surfaces. The upper and lower arc-shaped grooves are combined to form mounting holes. Bearings are installed in the mounting holes. The shafts 13 at both ends of the first helical gear 4 are inserted into the inner rings of the bearings.

[0029] The bearings ensure that the first helical gear can rotate smoothly.

[0030] In this embodiment, multiple positioning plates 14 are installed on both sides of the connecting sleeve 6, and multiple positioning grooves are provided at one end of the cleaning brush head 5, with the positioning plates 14 inserted into the positioning grooves.

[0031] The positioning plate and positioning groove can position the cleaning brush head, preventing it from rotating on its own and ensuring that the cleaning brush head can only be rotated by the central shaft.

[0032] In this embodiment, the interior of the housing is also provided with a main board 15 electrically connected to the motor 9, which can control the motor.

[0033] In this embodiment, the shaft 13 on one side of the first helical gear 4 is provided with a first parallel surface 16, and the inner wall on one side of the connecting sleeve 6 is provided with a second parallel surface. The second parallel surface is fitted to the first parallel surface 16.

[0034] The connecting sleeve can be positioned by the first parallel plane and the second parallel plane, so that the positioning hole on the connecting sleeve can be set perpendicularly to the positioning hole on the shaft, which facilitates the subsequent insertion of the shaft.

[0035] Working principle: After the motor is started, it drives the second helical gear. The rotation of the second helical gear drives the first helical gear, and simultaneously drives the shaft, central shaft and cleaning brush head. Adjacent cleaning brush heads form an angle greater than zero degrees, ensuring that the movement direction of each rotatable cleaning brush head is different. The multiple cleaning brush heads are distributed in a ring structure, which can cross the longitudinal bar on the grill, reducing the probability of jamming. The cleaning brush head is equipped with several bristles that extend radially from the rotating shaft. These bristles are made of high temperature resistant material, which can quickly clean the surface after the grill is used, and can also reach into the side to ensure cleaning effect.

[0036] When the cleaning brush head needs to be replaced, the retaining piece can be unscrewed, allowing the cleaning brush head to be taken out directly along the central axis. To avoid disassembly trouble caused by obstruction inside the housing, the arc-shaped clamp can be pried open directly, and the insert shaft can be pulled out from the positioning hole. After the insert shaft is no longer in place, the central shaft can be removed from the shaft, and the cleaning brush head can be moved to the outside before removing the retaining piece, which facilitates the operation.

[0037] Example 2:

[0038] like Figures 5-6 As shown, unlike Embodiment 1, the two cleaning brush heads are arranged horizontally to each other, i.e., the two cleaning brush heads are coaxially arranged and share a common first helical gear. The original three first helical gears have been changed to two first helical gears. Since the arrangement of the three cleaning brush heads has changed, the original uniform triangular arrangement has been broken. The three cleaning brush heads include one first cleaning brush head 51 and two second cleaning brush heads 52. The two second cleaning brush heads are coaxially arranged. In this way, when driven synchronously by the second helical gear, the two second cleaning brush heads have the ability to move in one direction. That is, they no longer make circular rotation movements like in Embodiment 1. In this embodiment, the two second cleaning brush heads can move in one direction. That is, the cleaning device in this embodiment has the ability to move in one direction, and no longer requires manual movement to complete the displacement.

[0039] 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.
