[0032] In order to make the person skilled in the art better understand the application scheme, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. The embodiments described below are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 5The stirring rod with safety protection device provided by the application comprises a connecting part 1, a semi-closed protective cover 2, a stirring blade 3 and a baffle assembly 4. The inside of the connecting part 1 is provided with a transmission shaft 11. The semi-closed protective cover 2 is fixed to one end of the connecting part 1. The length of the connecting part 1 determines the length of the whole stirring rod. The connecting part 1 can be cylindrical or thin-waisted with thick ends, which is not limited here. The semi-closed protective cover 2 in the shape of U is fixed to the end of the connecting part 1. The bottom of the protective cover 2 is not closed, so that an opening area is formed at the bottom of the protective cover 2. The stirring blade 3 is arranged at the end of the transmission shaft 11 and in the protective cover 2. The stirring blade 3 can rotate and cut under the driving of the transmission shaft 11. The baffle assembly 4 comprises a fixed baffle 41 and at least one movable baffle 42. In this embodiment, the fixed baffle 41 is detachably fixed to the opening area at the bottom of the protective cover 2, which can be conveniently disassembled and cleaned. In other embodiments, a fixed mode that cannot be disassembled can also be selected, which should fall within the protection scope of the application. The fixed baffle 41 can shield part of the opening area, and the remaining opening area can form a feeding area. The movable baffle 42 is movably arranged on the fixed baffle 41. In this embodiment, the movable baffle 42 can rotate relative to the fixed baffle 41. In other embodiments, the movable baffle 42 can also slide relative to the fixed baffle 41. The protective cover 2 and the baffle assembly 4 form a semi-closed stirring cavity. Blocky food materials can enter the stirring cavity through the feeding area. A water inlet 5 is arranged between the protective cover 2 and the baffle assembly 4. The side of the movable baffle 42 towards the stirring cavity is provided with a liquid force driving device 421. In this embodiment, the number of the liquid force driving device 421 is only one. The liquid force driving device 421 is a protruding baffle fixed to the inner side of the movable baffle 42. It can also be other devices that can be driven after feeling the water flow. The fixed baffle 41 is provided with a limiting device 411 corresponding to the position of the edge of the movable baffle 42. The movable baffle 42 is connected with a reset device 6. The limiting device 411 can be a stop block or a stop column. The position of the limiting device 411 can also correspond to the position of the sliding groove opened on the movable baffle 42. It only needs to limit the position of the movable baffle 42, keep the movable baffle 42 in the correct position and avoid the movable baffle 42 from continuing to rotate. The reset device 6 is a torsion spring, which can also be other devices that can reset the movable baffle 42 to the initial position. The main function of the reset device 6 is to reset the movable baffle, so that it can be kept in the correct position when reset. Therefore, the reset device 6 is a torsion spring with pre-tightening force.

[0035] When the movable baffle 42 is opened and rotated to the maximum range, in addition to the limiting of the limiting device 411, the torsion of the torsion spring reaches the maximum and exceeds the water flow thrust, which can also play a limiting role.

[0036] When the machine is started, the stirring blade 3 begins to rotate, and when the stirring rod is not immersed in the stirring cup, the movable baffle 42 is in the closed state under the action of the reset device 6, that is, the movable baffle 42 can shield the feeding area when it is in the reset state, at this time, the user's hand and the block-shaped food material cannot enter the inside of the stirring cavity, thereby preventing accidental injury to play a protective role. When the stirring rod is immersed in the stirring cup, the liquid such as water, milk or juice in the stirring cup can enter the inside of the stirring cavity through the water inlet 5 between the guard 2 and the baffle assembly 4, and the liquid under the action of the high-speed stirring of the stirring blade 3 will form a rotating water flow, which can drive the liquid force driving device 421 on the movable baffle 42, and the pushing force of the liquid force driving device 421 is greater than the reset force of the reset device 6, so that the movable baffle 42 rotates relative to the fixed baffle 41, at this time the feeding area is partially opened, and some small pieces of food material can enter the inside of the stirring cavity, and when the movable baffle 42 is rotated to the limiting device 411, the edge of the movable baffle 42 is blocked by the limiting device 411, so that the movable baffle 42 stops rotating, at this time the feeding area is completely opened, that is, the movable baffle 42 can expose the feeding area when it is in the force-driven state, at this time the block-shaped food material can enter the inside of the stirring cavity for stirring and cutting, when the stirring rod leaves the stirring cup, the liquid in the stirring cup flows out, at this time the pushing force of the liquid force driving device 421 is less than the reset force of the reset device 6, under the action of the reset device 6, the movable baffle 42 is reset to the initial position, thereby shielding the feeding area, and the user's hand and the block-shaped food material cannot enter the inside of the stirring cavity.

[0037] The operation process is simple, only the machine needs to be started to realize the operation, without other operation buttons, when the stirring rod is not immersed in the liquid in the stirring cup, the feeding area will not be opened, thereby protecting the user's hand from accidental injury, making the user operation simple and easy to use; the product structure is also extremely simple, which greatly reduces the product manufacturing cost, and because the parts are very few, the probability of part damage can also be greatly reduced, thereby improving the competitiveness of the product, to meet the increasing quality requirements of production enterprises.

[0038] In the embodiment, the fixed baffle 41 is provided with a buckle, the side edge of the guard 2 is provided with a buckle hole corresponding to the buckle, and the buckle of the fixed baffle 41 is buckled on the buckle hole to realize fixation.

[0039] Embodiment 2

[0040] Please refer to Figures 6 to 8As a further optimization of embodiment 1, the water inlet 5 in this embodiment is arranged on the side of the shroud 2. In other embodiments, the water inlet 5 can also be arranged on the baffle assembly 4, which can be in the form of a hole or a large opening, as long as it can allow the liquid in the stirring cup to enter the stirring cavity when the stirring rod is immersed in the stirring cup. It can also be designed to have a smaller size of the baffle assembly 4, so that there is a small gap between the baffle assembly 4 and the shroud 2, which can only allow the user's fingers to enter, so that the liquid can enter the inside of the stirring cavity. For example, the end of the shroud 2 is designed in a wavy shape, and there is a gap between the edge of the wavy shroud 2 and the baffle assembly 4, so that the liquid can enter the inside of the stirring cavity. More preferably, the water inlet 5 in this embodiment has multiple water inlets, so that the liquid in the stirring cup can quickly enter the inside of the stirring cavity, and the shape of the water inlet 5 is oval, so that the size of the water inlet 5 is larger, avoiding the blockage of the water inlet 5 by residues. In other embodiments, the shape of the water inlet 5 can also be other shapes, as long as it can allow the liquid in the stirring cup to enter the stirring cavity when the stirring rod is immersed in the stirring cup.

[0041] Further, the liquid force driving device 421 is perpendicular to the rotation direction of the stirring blade 3, and it receives the maximum force under the action of the water flow. In other embodiments, the liquid force driving device 421 can also form an angle with the rotation direction of the stirring blade 3, and the smaller the angle, the smaller the force received by the water flow. However, it is best not to be parallel to the rotation direction of the stirring blade 3, otherwise the liquid force driving device 421 will receive very weak force from the water flow, making it difficult for the liquid force driving device 421 to rotate under the action of the water flow.

[0042] Further, the movable baffle 42 and the fixed baffle 41 are both semicircular in shape. In other embodiments, the movable baffle 42 and the fixed baffle 41 can also be trapezoidal or other irregular shapes, and only one movable baffle 42 and one fixed baffle 41 are needed to block the feeding area and open the feeding area. In other embodiments, one fixed baffle 41 and multiple movable baffles 42 can also be used in combination. For example, two movable baffles 42 are designed, and each fixed baffle 41 and each movable baffle 42 can be one-third of a circle. When the fixed baffle 41 and the movable baffle 42 block the feeding area, the two movable baffles 42 are rotated under the action of the water flow and are blocked by the limiting device 411, thereby opening the feeding area.

[0043] Further, the liquid force driving device 421 has two, and the two liquid force driving devices 421 are arranged at the edges of the two ends of the movable baffle 42, that is, the two liquid force driving devices 421 are located on the left and right sides of the movable baffle 42, so as to improve the driving force of the liquid force driving device 421, when the liquid force driving device 421 is forced and rotated by half a circle, one end of the movable baffle 42 is blocked by the limiting device 411, so as to stop rotating, that is, the feeding area is opened; when the liquid force driving device 421 is not forced, it can rotate back by half a circle under the action of the reset device 6, and the other end of the movable baffle 42 is blocked by the limiting device 411, and does not continue to rotate, so as to block the feeding area.
