Description

Technical Field

[0001] This utility model relates to the technical field of fuel feeding devices for barbecue grills, and in particular to an anti-clogging fuel feeding device for barbecue grills. Background Technology

[0002] A barbecue table is a device that combines cooking and dining functions, primarily used in commercial catering or outdoor activities. In a barbecue table, the feeding device of the combustion chamber typically uses a hopper as a key component for fuel storage and transportation, temporarily storing fuel and then conveying it into the barbecue grill via a conveyor. For example, Chinese patent CN202021889029.7 discloses a tabletop barbecue grill that is easy to clean, comprising a grill body, and a hopper and oil box connected to the side of the grill body. The grill body contains a grill rack, an oil collection tray, a fire shield, and a fuel box. One side of the fuel box has a combustion chamber, and the other side of the fuel box is connected to the hopper. An auger and air duct are movably installed inside the fuel box; one end of the auger is located in the combustion chamber, and the other end is connected to a motor. This grill feeds fuel into the fuel box through the hopper, and the motor on the side of the fuel box uses the auger to deliver the fuel to the combustion chamber for ignition. However, because the hopper in this grill transports blocky charcoal fuel, its sloping sidewall is prone to charcoal jamming. Utility Model Content

[0003] In view of this, the present invention provides an anti-clogging fuel feeding device for a barbecue grill to solve the above problems.

[0004] An anti-clogging fuel feeding device for a barbecue grill includes a feeding channel, an anti-jamming component disposed within the feeding channel, and a discharge channel disposed on one side of the feeding channel. The feeding channel has a hopper portion on the side near the discharge channel. The anti-jamming component includes a drive motor, a rotating rod disposed at the output end of the drive motor, and a plurality of stirring blades spaced apart on the rotating rod. The length direction of the rotating rod is parallel to the arrangement direction of the feeding channel and the hopper portion. The stirring blades are broken at any radius, forming an upward-curved end and a downward-curved end. The upward-curved end and the downward-curved end have opposite protrusion directions, and both are connected to the stirring blades via an arc transition.

[0005] Furthermore, a feed inlet is provided on one side of the feed channel.

[0006] Furthermore, the lateral cross-sectional area of ​​the hopper gradually decreases from the side away from the discharge channel toward the side closer to the discharge channel, and the output end of the hopper is connected to the input end of the discharge channel.

[0007] Furthermore, the drive motor is fixedly mounted on the side wall of the feed channel, and the rotating rod passes through the side wall of the feed channel and is located inside the feed channel.

[0008] Furthermore, the end of the rotating rod is located inside the hopper section, and a plurality of the stirring blades are located inside the hopper section.

[0009] Furthermore, the stirring plate is circular in shape, with its center located on the axis of the rotating rod.

[0010] Furthermore, the discharge channel is cylindrical and horizontally positioned inside the barbecue oven, and the discharge channel has an automatic fuel-pushing device.

[0011] Compared with existing technologies, the anti-clogging fuel feeding device for barbecue grills provided by this utility model is driven by the drive motor, which rotates multiple stirring blades. This stirs the fuel located in the hopper, preventing accumulated fuel from getting stuck in the hopper and allowing the fuel to smoothly enter the discharge channel.

[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] like Figure 1The diagram shows a structural schematic of the anti-clogging fuel feeding device for a barbecue grill provided by this utility model. The anti-clogging fuel feeding device for a barbecue grill includes a feeding channel 10, an anti-jamming component 20 disposed within the feeding channel 10, and a discharge channel 30 disposed on one side of the feeding channel 10. It is conceivable that the anti-clogging fuel feeding device for a barbecue grill also includes other functional modules, such as a power module, applewood fuel, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0018] Please refer to this. Figures 2 to 4 The feed channel 10 has a feed inlet 11 on one side for inputting fuel. The feed channel 10 is vertically arranged so that the fuel can enter the discharge channel 30 by its own gravity. The feed channel 10 has a hopper section 12 on the side near the discharge channel 30. The lateral cross-sectional area of ​​the hopper section 12 gradually decreases from the side away from the discharge channel 30 toward the side near the discharge channel 30, and the output end of the hopper section 12 is connected to the input end of the discharge channel 30.

[0019] The feeding assembly 20 includes a drive motor 21, a rotating rod 22 disposed at the output end of the drive motor 21, and a plurality of stirring blades 23 spaced apart on the rotating rod 22.

[0020] The drive motor 21 is fixedly mounted on the side wall of the feed channel 10, and the rotating rod 22 passes through the side wall of the feed channel 10 and is located inside the feed channel 10. The drive motor 21 can drive the rotating rod 22 to rotate, thereby driving the stirring plate 23.

[0021] The length direction of the rotating rod 22 is parallel to the arrangement direction of the feed channel 10 and the hopper section 12, and the end of the rotating rod 22 is located inside the hopper section 12, where multiple stirring blades 23 are located. When the drive motor 21 drives and rotates the multiple stirring blades 23, it agitates the fuel located in the hopper section 12, thereby preventing the fuel from accumulating and getting stuck in the hopper section 12, allowing the fuel to smoothly enter the discharge channel 30.

[0022] The stirring blade 23 is generally circular, with its center located on the axis of the rotating rod 22. The stirring blade 23 is broken at any radius, forming an upward-curved end 24 and a downward-curved end 25. The upward-curved end 24 and the downward-curved end 25 have opposite protrusion directions and are connected to the stirring blade 23 via an arc transition. When the stirring blade 23 rotates with the rotating rod 22, the upward-curved end 24 and the downward-curved end 25 increase the axial movement path of the stirring blade 23, thereby maximizing fuel agitation, improving mixing efficiency, and preventing fuel jamming.

[0023] In another embodiment, the drive motor 21 is located on one side of the hopper section 12, and the length direction of the rotating rod 22 is perpendicular to the arrangement direction of the feed channel 10 and the hopper section 12. The rotating rod 22 is located inside the hopper section 12. Among the plurality of stirring blades 23, the diameter of the stirring blade 23 located at the center of the hopper section 12 gradually decreases towards both sides along the length direction of the rotating rod 22, to ensure that the stirring path of the plurality of stirring blades 23 can cover most of the area inside the hopper section 12, preventing material jamming due to incomplete stirring.

[0024] The discharge channel 30 is cylindrical and horizontally positioned inside the barbecue grill. The discharge channel 30 contains an automatic feeding device, consisting of a motor and a auger. This device drives the auger to rotate via the motor, propelling the fuel and discharging it through the discharge channel 30. This automatic feeding device is existing technology and will not be described in detail here.

[0025] Compared with the prior art, the anti-clogging fuel feeding device for barbecue grills provided by this utility model is driven by the drive motor 21, which drives multiple stirring blades 23 to rotate. This stirs the fuel located in the hopper 12, thereby preventing the accumulated fuel from getting stuck in the hopper 12 and allowing the fuel to smoothly enter the discharge channel 30. The upward-curved end 24 and the downward-curved end 25 can increase the axial movement path of the stirring blades 23, thereby maximizing the stirring of the fuel, improving the stirring efficiency, and preventing fuel jamming.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
