Description

TECHNICAL FIELD

[0001] The utility model relates to a structure technical field of breaking wall machine, specifically related to a breaking wall machine with double -layer stirring cutter. BACKGROUND

[0002] The working principle of the breaking wall machine is to cut the food material through the high-speed rotating blade, thereby realizing rapid crushing, making the nutrients such as vitamins, minerals and proteins in the food material fully release, and being more easily absorbed by the human body. For example, the patent document with the announcement number CN220369892U discloses a multifunctional breaking wall machine, which is provided with a high-speed rotating blade inside the cup body. The breaking wall machine can not only be used for crushing dry food materials (such as peanut powder), but also can be used for making water-containing drinks such as fruit juice and soybean milk or ingredients. In the latter making process, the blade has the function of stirring while cutting the food material, which can fully mix the food material and water.

[0003] At present, most of the breaking wall machines are designed as shown in the above-mentioned patent document, only a single cutter or a single layer of blade is adopted, and the blade is usually subjected to bending or bending treatment. When the blade rotates, the cutting edge part is mainly used for cutting, and other structures bear the task of stirring. However, the resistance received by the cutter during stirring mainly comes from the collision with the liquid and the food material, which limits the cutting speed and effect to some extent, specifically, it can cause the overall efficiency of the blade to decrease, especially when processing viscous or large food materials, the cutting effect and mixing uniformity may not be ideal. SUMMARY

[0004] In view of the problems in the related art, the utility model provides a breaking wall machine with double-layer stirring cutters, which can have better cutting effect and stirring effect at the same time.

[0005] The utility model is realized as follows:

[0006] A breaking wall machine with double-layer stirring cutters, comprising a base and a cup body, the cup body is installed on the upper side of the base; a driving unit is arranged in the base; the double-layer stirring cutter comprises a transmission shaft and two cutters, which are an upper rotating cutter and a lower rotating cutter; the transmission shaft vertically penetrates the center of the bottom of the cup body; the lower part of the transmission shaft is in transmission connection with the driving unit; the upper rotating cutter and the lower rotating cutter are spaced apart in an up-down manner and are fixed to the upper end of the transmission shaft.

[0007] A fixing ring is arranged between the upper rotating cutter and the lower rotating cutter; the fixing ring is sleeved on the transmission shaft; the upper side surface of the fixing ring abuts against the upper rotating cutter, and the lower side surface abuts against the lower rotating cutter; the height of the fixing ring is 0.5-10 mm.

[0008] The retaining ring limits and fixes the interval between the two blades. Both blades have cutting and stirring functions. The interval between the blades is designed to prevent interference during rotation and to ensure that the cutting and stirring forces of the two blades do not stray far apart or disperse. Even if the rotation speed is slightly reduced due to resistance during stirring, good cutting and stirring effects can still be guaranteed.

[0009] As a further optimization of the above solution, both the center of the upper rotary cutter and the center of the lower rotary cutter have a connection port;

[0010] The top of the transmission shaft is provided with a first mounting platform and a second mounting platform from bottom to top; the upper side of the second mounting platform is provided with a boss; the radial dimension of the first mounting platform is larger than the radial dimension of the transmission shaft; the radial dimensions of the first mounting platform, the second mounting platform and the boss decrease sequentially.

[0014] As a further optimization of the above solution, the transmission shaft is made of a single piece of metal / alloy material; the boss is formed as a riveted part;

[0015] After riveting, the boss deforms circumferentially to limit and fix the upper rotary cutter.

[0016] The riveting process involves applying pressure from top to bottom towards the top of the boss. During riveting, under pressure, the second mounting platform also pushes the lower cutting tool outwards, making the lower cutting tool more securely fixed.

[0017] Alternatively, the boss can be threaded around its perimeter and a nut installed to secure the upper rotary cutter. However, the nut in this solution is prone to falling off during rotation.

[0018] As a further optimization of the above solution, both the second mounting platform and the boss are columnar structures; both the second mounting platform and the boss have at least one flat section on their sides.

[0019] The connection port is adapted to the flat position.

[0025] As a further optimization of the above solution, the heating unit is a heating tube; the heating tube is arranged around the bottom of the outer side of the heat-conducting part.

[0026] As a further optimization of the above solution, the drive unit has an output shaft, the upper end of which is connected to the transmission shaft, and the lower end of the output shaft is also provided with a cooling fan; the base is also provided with heat dissipation holes / heat dissipation grooves / heat dissipation vents.

[0027] Cooling fans and ventilation holes are used to dissipate heat from the equipment, preventing the electronic components from overheating.

[0028] As a further optimization of the above solution, a temperature sensing unit is also included; the temperature sensing unit is located in the middle cavity region of the heating tube; the temperature sensing unit has a probe part, which passes through the heat-conducting part and enters the inner cavity of the cup body.

[0029] The temperature sensing unit provides temperature data feedback to the temperature control unit.

[0030] As a further optimization of the above solution, the upper end of the output shaft has a slot; the lower part of the transmission shaft is adapted to the slot; the output shaft and the transmission shaft are detachably connected.

[0031] It facilitates the disassembly and cleaning of the cutting tools, as well as the replacement and maintenance of the cutting tools.

[0033] This invention provides a blender with double-layered mixing blades. A fixing ring restricts and fixes the spacing between the two blades. Both layers of blades have cutting and mixing functions. The spacing between the blades serves two purposes: first, to prevent interference during rotation; and second, to ensure that the cutting / mixing forces of the two blades do not stray too far apart or disperse. Compared to existing technologies, it offers better cutting and mixing effects. Attached Figure Description
