Detailed Description

The first embodiment is as follows:

fig. 1 is a schematic structural diagram of a first embodiment of the present invention. A slagless food processor comprises a cup body 1 and a grinding device arranged in the cup body 1, wherein the grinding device comprises a grinding cover 2 arranged at the bottom of the cup body 1, a rotary grinding disc 3 driven by a rotating shaft 41 and arranged in the grinding cover 2 and a tightening device 5, the grinding cover 2 is provided with a first grinding surface 21 facing to the cup bottom, the rear end of the grinding cover 2 is provided with an opening 20 penetrating through the first grinding surface, the rotary grinding disc 3 is provided with a second grinding surface 31 matched with the first grinding surface 21 to form plane grinding, the tightening device 5 has a downward tightening pulling force F to the grinding cover 2, so that the first grinding surface 21 is tightened on the second grinding surface 31 and is positioned below the first grinding surface 21, a material passing port 22 is arranged on the peripheral wall of the grinding cover 2, and in the pulping process, the materials are subjected to plane grinding between the first grinding surface 21 and the second grinding surface 31, the grinding cup 2 drives the first grinding surface 21 to float in the axial direction above the second grinding surface 31.

In this embodiment, the base 6 is disposed at the bottom of the cup body 1, the motor 4 is fixed in the base 6, the tightening device 5 is a spring under a stretching state, one end of the spring is connected to the front end of the grinding cover 2, the other end of the spring is fixedly connected to the bottom of the cup body 1, and the grinding cover 2 is contracted by the spring to realize that the first grinding surface 21 is tightened to the second grinding surface 31.

In this embodiment, the rotating grinding disc is screwed to the rotating shaft through threads. The tightening device in this embodiment is a spring in a stretched state, and the tightening force is F, which is a downward elastic force of the spring, and the grinding cover approaches the rotating grinding disc under the action of the elastic force (the tightening force F), so that the gap value between the first grinding surface on the corresponding grinding cover and the opposite second grinding surface on the rotating grinding disc is reduced, thereby improving the grinding and crushing efficiency of the material.

In the residue-free food processor of this embodiment, when the rotating grinding disc is mounted on the rotating shaft and the grinding cover is mounted on the bottom of the cup body, the grinding device further has a tightening device, i.e. a spring, which generates a downward moving elastic force (tightening force F) to the grinding cover, and the elastic force (tightening force F) is combined with the gravity of the grinding cover itself, so that the first grinding surface of the grinding cover is close to the second grinding surface on the rotating grinding disc, and the rotating grinding disc supporting grinding cover is formed. In the pulping process, when the rotating shaft drives the rotating millstone to rotate at a high speed, the material and the serous fluid enter a gap between the first grinding surface and the second grinding surface through the opening at the rear end of the grinding cover. In the grinding earlier stage, material particle diameter is great, when the material granule passes through the clearance between first abrasive surface and the second abrasive surface, under the fluid pressure and the material granule backward extrusion force effect to two abrasive surfaces, grind the cover and can overcome the spring to grinding the decurrent elasticity of cover (the power F that sticiss) and grind the gravity of cover self passively, thereby can rebound in the axial, the clearance value increase between first abrasive surface and the second abrasive surface, the bold material granule can be smooth and easy through the clearance of first abrasive surface and second abrasive surface, and grind into less granule by first abrasive surface and second abrasive surface centre gripping.

The food processor of the embodiment just enables the grinding cover to float upwards in the axial direction above the rotary grinding disc under the elastic force action of the spring, so that the prepared slurry beverage is free from filtering and residue. Meanwhile, the grinding cover in the embodiment can float axially, so that the gap value between the first grinding surface and the second grinding surface can be adjusted in a self-adaptive manner, the load borne by the motor during the pulping of the food processing machine in the early stage of grinding is greatly reduced, and the pulping noise is reduced. In addition, the slag-free food processor of the embodiment has the advantages that the grinding cover and the rotary grinding disc are convenient to disassemble and easy to clean.

For the present embodiment, the axial floating distance of the polishing cover is H, i.e. the maximum value of the gap between the first polishing surface and the second polishing surface when the polishing cover floats. The inventor finds that the diameter of the bean material particles is about 10mm generally, and if the axial floating distance of the grinding cover is too large and is larger than 10mm, in the floating process of the grinding cover, large materials can pass through the gap between the first grinding surface and the second grinding surface very lightly, so that the large materials lose the opportunity of being ground and broken, and poor grinding is easily caused. Thus, for the present embodiment, the axial float distance H of the grinding cup is no greater than 10mm, such as H being 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10 mm.

The inventor finds that the rotating grinding disc and the grinding cover have manufacturing tolerance in the process manufacturing process and tolerance accumulation in the assembly process, so that the poor installation between the parts is easily caused. Based on this, in order to achieve the close fit between the first polishing surface and the second polishing surface, the movable gap H1 between the polishing cup and the bottom wall of the cup body is required to be at least greater than 0.5 mm. In the present embodiment, the tightening assembly disposed between the grinding cap and the cup body is a spring, and the corresponding clearance H1 is required to be larger so as to be able to mount the spring, for the present embodiment, H1 is generally required to be not greater than 20mm, and if H1 is too large, the number of turns, tension and strength of the spring are combined, so that the cost will be increased, which is not favorable for mass production.

Example six:

fig. 11, 12, 13, 14 and 15 show a schematic structural diagram of a sixth embodiment of the present invention. The embodiment is an improvement on the structure of the grinding cover.

The grinding cover in this embodiment includes a cover-shaped body 28 and a floating grinding disc 29 detachably connected to the cover-shaped body 28, a limiting portion 281 is provided inside the cover-shaped body 28 to prevent the floating grinding disc 29 from floating upward, the floating grinding disc 29 is supported by the rotating grinding disc 3, and the first grinding surface 21 is a lower surface of the floating grinding disc 29. Wherein, a speed reducing structure for reducing the movement of the liquid flow is arranged between the first grinding surface 21 and the second grinding surface 31. The decelerating structure in this embodiment comprises a protrusion 219 on the first abrasive surface 21 and a recess 319 arranged on the second abrasive surface 31, the protrusion 219 protruding into the recess 319.

For the embodiment, the floating grinding disc is positioned between the rotating grinding disc and the limiting part, and when the rotating grinding disc rotates, the floating grinding disc can axially float between the rotating grinding disc and the limiting part due to different pressures of liquid flow between the upper gap and the lower gap. Therefore, in the pulping process, the gap value between the rotary grinding disc and the floating grinding disc can be adjusted in a self-adaptive mode, when the gap value between the rotary grinding disc and the floating grinding disc is reduced, the materials are clamped between the two grinding discs to be ground and crushed, the grinding efficiency is higher, and the materials are ground more finely. And when there is the bold material granule, the clearance value between rotatory mill and the unsteady mill can also the self-adaptation increase to do benefit to the process grinding of bold material granule, not only the load that the motor bore is less, and the noise value during slurrying reduces, moreover, also can not have the card phenomenon of dying between rotatory mill and the unsteady mill. Even if the rotating shaft (motor shaft) has upward axial float and drives the rotary grinding disc to be far away from the floating grinding disc, the floating grinding disc can also realize self-adaptive adjustment of the grinding gap between the rotary grinding disc and the floating grinding disc through the self floating effect, and the efficiency of grinding and crushing materials is improved. Simultaneously, because the mill that floats can the self-adaptation axial float, the mill that floats is difficult to hide the sediment, hides dirty, and it is easy to wash to, when grinding different kinds of materials, the mill that floats can be dismantled and change, simple structure, simple to operate, even the mill that floats takes place wearing and tearing or damage, the cost of dismouting change is also lower.

In addition, for the embodiment, because the speed reduction structure is arranged between the rotary grinding disc and the floating grinding disc, the grinding surfaces of the rotary grinding disc and the floating grinding disc are divided into an inner section grinding area and an outer section grinding area, when the material and the slurry flow pass through the inner section grinding area at a high speed, the material is quickly ground, and when the material and the slurry flow pass through the speed reduction area of the rotary grinding disc and the floating grinding disc, the flow velocity of the liquid flow is reduced, so that when the material passes through the outer section grinding area, the grinding time of the material is longer, and the grinding efficiency is further improved. Of course, the deceleration structure is not limited to the structure of the embodiment, and the deceleration structure may also be an effect of reducing the liquid flow and improving the grinding efficiency by arranging the protrusions on the rotating grinding disc and the grooves matched with the protrusions on the floating grinding disc. Of course, the division of the grinding teeth into two grinding zones is not limited to the decelerating structure of the present embodiment, or the rotating grinding disc and/or the floating grinding disc itself may have two different grinding zones.

It should be noted that the above structural changes to the present embodiment can also be applied to other embodiments of the present invention.
