Figure 13 is the enlarged view of part II of figure 13. [Concrete implementation method] 10 Shown in figure 1, 2, 3, and 4, in the implementation example of this practical new type portable food processor, this portable food processor comprises the container 100, container cover component 200 and food processing component 300 that is set inside the container 100. The container cover component 200 comprises the cover the covers the opening of the container 100, knob 230 that is set on the top of the 15 cover and projects and the transmission mechanism 250 that is set inside the cover. The knob 230 drives the food processing component 300 to rotate relative to the container 100 through the said transmission mechanism 250. Treatment such as cutting and stirring the food is conducted by using the rotation of the food processing component 300 relative to the container 100. 20 The surface of the inner wall of container 100 comprises the primary embossment 111 that is set along the axis of the container 100 (see figure 4). This means that the primary embossment 111 extends from the top of inner wall of container 100 to its bottom. The primary embossment 111 can increase the resistance between food processing component 300 and the food when the food processing component 300 25 rotates, thus making better cutting effect of the food. The number of the primary embossment 111 can be set four or more. Two dents 112 are set on the outside surface of the container 100, which are distributed somatically on the outside surface of container 100 and facilitate the user to hold the container 100 with only one hand during use and make the whole food 30 processor stable. The user may use the hand to rotate the knob 230 for operation. In addition, the setting of the two dents 112 makes convenience for the user to cooperate with the rotation in both positive direction and negative direction to quicken 6 the cutting speed of the portable food processor. In the implementation example, because the said two dents 112 are depressed and projects over the inner surface of container 100, two dents 112 has the function to increase the resistance of food inside container 100. The above four primary embossments 111 may be divided into 5 two groups and each group comprises two primary embossments 111. The primary embossment 111 of one group is distributed evenly regarding one dent 112 as the center. This means that one primary embossment 111 is distributed evenly at the symmetrical position of the above said primary embossment 112. Shown in figure 1, 4, 8 and 13, in the implementation example, the cover is made up 10 of upper case 210 and lower case 220.The upper case 210 and lower case 220 is connected and fixed together through fasteners and the cavity is formed between upper case 210 and lower case 220. The transmission mechanism 250 is set in the cavity. The rotating nut 211 that is fitting with the shape of knob 230 is set on the top surface of the upper case 210 (the top of container cover component 200). The lower 15 case 220 matches the opening of container 100, enabling the lower case 220 can cover the opening of container 100. The primary position hole 212 is set inside the knob nut 211 and the primary position pillar 231 that projects towards upper case 210 in the center of knob 230. At the end of primary position pillar 231, at least one axial nick 232 that divides the end of primary 231 into many fixed elastic slice 233 is set at 20 the primary position pillar 231. Embossment 234 is set around the circumferential surface of each fixed elastic slice 233. When the primary position pillar 231 of knob is inserted to the primary position hole 212 of knob nut, the fixed elastic slice 233 deforms, which makes the size of end of primary position pillar 231 become smaller, enabling it to insert into the primary position hole 212. When the end of primary pillar 25 231 passes through the upper case 210, the fixed elastic slice 233 restores to its original state while the embossment 234 on the circumferential surface of the fixed elastic slice is blocked around the circumference of primary position hole 212. This makes the end of primary position 231 become bigger and positions the primary position pillar 231 in the primary position hole 212. It means that the knob 230 is 30 positioned in the knob nut 211 of the upper case. At the same time, the knob 230 can rotate around the central shaft of the primary position hole 212 relative to upper case 210. The rotating central shaft of the knob 230 is the central axis of primary position hole 212. Shown in figure 2, 3, 4, 9 and 10, the circumference of the inner wall of knob 230 35 comprises gear slot 231 and the inner tooth is set on the slot wall of gear slot 231; the transmission mechanism 250 comprises transmission gear 251, driven gear 252 7 and driven shaft 253. The center of the transmission gear 251 comprises a screw hole 251 a. The driven gear251 is fixed inside the upper case 210 by using the screw to penetrate though the screw hole 251a of the transmission gear. This means that the transmission gear 251 is fixed on one side of the upper case 210 that is close to 5 lower case 220, the transmission gear 251 is located at the cavity of between upper case 210 and lower case 220. The transmission gear 251 comprises a cylindrical gear 254 that engages with the inner tooth of gear slot 231 and a bevel gear 255 that engages with the driven gear 252. The secondary position pillar 221 is set on one side of the lower case 220 that is close to upper case 210 and the secondary position 10 pillar 221 is set with the primary through-hole 221a and the driven gear 252 is set with the secondary through-hole 252a. The driven gear fits with the driven shaft 253 by using a screw to pass through the secondary through hole 252a of the driven gear and the primary through hole 221a of the secondary position pillar 221. The driven gear 252 can be fixed on one end of the driven shaft 253 and the rotation of the 15 driven gear 252 is set on the secondary position pillar 221 of the lower case. The driven gear 252 and the driven shaft 253 are located at two sides of the lower case 220 respectively. In the preferred implementation example, the bottom part of the driven shaft 253 is set with hexagonal pillar 253a while the supper part is set with cylinder 253b that 20 matches the bottom end of the primary hole 221a of the lower case. The secondary hexagonal nut 253c is set at the end of cylinder 253b on the top of the driven shaft. The said driven gear 252 comprises the third position pillar 252b that projects towards container 100 and matches the said primary nut 253c. when the screw is used to fix the driven gear 252 and driven shaft 253 on the secondary position pillar 25 221, the third position pillar 252b of the driven gear can pass through the primary through-hole 221a of the secondary position pillar 221 and insets to the inside of secondary nut 253c of the driven shaft, making driven gear 252 drive the driven 253 rotate. When the operator rotates the knob 230 with hand, knob 230 can rotate around its 30 won rotating central axis (the central axis of the primary position through-hole 212). The gear slot 231 of the knob fits with the cylinder gear 254 of the transmission gear, which makes the knob 230 drive transmission gear 251 to rotate. As the bevel gear 255 of the transmission gear fits with driven gear 255, the transmission gear 251 drives the driven gear 252 to rotate. The driven gear 252 drives the food processing 35 components 300 to rotate inside the container 100 through driven shaft 253 to cut the food. 8 The food processing component 300 can be divided into many components with different functions such as blade component and stirring component, etc. According to different food processing technology, components of different functions can be selected to be installed in container 100 to perform different treatment for the food in 5 container 100. In this preferred implementation example, take the food processing components 300 of blade components as the example to make elaboration. But the food processing components 300 in this preferred implementation comprises not only the blade components but also the components with other function. Shown in figure 5, 6, 11 and 12, in this implementation example, the blade 10 components 300a comprises central axis 310 presenting hexagonal cylinder, bell socket pillar 320, primary blade 330 and secondary blade 340. The primary central hole 311 that match the bottom end of driven shaft 253 is set on the top of central shaft 310. The step shaft 312 whose size is smaller than the size of the shaft is set at the bottom of the bell-socket pillar 253. The primary central center 311 of the 15 preferred central axis is the hexagonal central hole matching the hexagonal pillar 253a at the bottom of the driven shaft. This makes driven shaft 253 drive the central axis 310 to rotate. The hexagonal pillar 321 matching the first central hole 311 of the central axis is set on the top of bell-socket pillar 320 while counter hole 322 is set on the bottom. Camshaft 113 is set at the bottom inside container 100 that faces the 20 lower part of the driven shaft 253 (see figure 3 and 4). The counter hole 322 at the bottom of bell-socket pillar matches camshaft 113, which can position the lower end of bell-socket pillar 320 at the bottom of container 100. The primary central hole 311 of central shaft 310 is set a through-hole. The secondary central hole 321 of bell socket pillar is set with a screw hole 321 a and matches the screw hold 321 a by using 25 a screw to penetrate the primary central hole 311, which connects central axis 310 with bell-socket pillar 320. The outside of bell-socket pillar 320 is set with sleeve 350 that matches the size of central axis 310. The sleeve 350 is set at the outside of the hexagonal pillar 321 of the bell-socket pillar. Fixing hole 331 and 341 that match the external shape of shaft of bell-socket pillar 30 320 are set on one end or the middle of primary blade 330 and secondary blade 340. The fixing hole 341 of secondary blade is wrapped the outside of bell-socket pillar 320. The step 323 whose size is larger than the size of the shaft is set at the lower part of the bell-socket pillar 320. Use the lower end of sleeve 350 to press the secondary blade 340 on the step 323 of the bell-socket pillar. The fixing hole 331 of 35 the primary blade is made wrapping the outside of bell-socket pillar 320, making sleeve 350 between primary blade 330 and secondary blade 340. Fix the central axis 9 310 at the top end of bell-socket pillar 320 through screw and use the lower end of central axis 310 to press the primary blade 330 tightly at the upper end of sleeve 350 so that the primary blade 330 is fixed on bell-socket pillar 320. The lower end of sleeve 350 and the surface of step 323 of bell-socket pillar is slope surface, which 5 makes the secondary blade 340 present slope state in container 100 and produce better cutting effect for food. It is the same that the lower end of central axis 310 and the upper end of sleeve 350 are set as slope surface, making the primary blade 330 slope in container 100. When the user puts the food to be cut in container 100, covers the container cover 10 component and rotates knob 230, knob 230 drives the driven shaft 253 to rotate through transmission mechanism 250. As the driven shaft 253 has rotation connection with the blade components, the blade component is driven to rotate and begins to cut the food inside container 100. In addition, the primary embossment 111 and dents 112 on the inner surface of container 100 increase the friction of food in 15 container 100, guaranteeing better cutting effect. In the said practical new type food processor, the food processing components 300 can also function as the fin to stir the food. As shown in figure 7, the fin component 300b comprises central axis 31 Ob and two fins 350. The side edge of fin 350 is fixed on the circumferential surface of the central axis 31 Ob. The fin 350 can be made on 20 the central axis 310b through integration molding or fastened on the central axis 310b through fastening parts. In addition, the top end of central axis 310b is set with the central hole (not shown in the figure) that matches the bottom end of driven shaft 253, and the bottom end of central axis is set with the counter hole 312b that matches the camshaft set inside of the bottom of container 100. When it is used, the 25 fin 350 rotates around the central axis 310b to push the food in container 100 to realize the function of stirring the food. In the above implementation example, rotating central axis of the preferred set rotating knob 230 intersects with the rotating central axis of food processing component 300 and forms an acute angle. It is better to set the above said rotating 30 central axis at the same vertical plane and intersect with each other to form an acute angel of 0 90'. The rotating central axis of food processing component 300 coincides with the central axis of driven shaft 253. It means that the rotating central axis of knob 230 and the central axis of driven shaft 253 are set in the same vertical plane and intersect with each other to form an acute angle, thus making the knob 230 35 set at one side of container cover component not the right top of upper case 210. 10 This ensures that the hand need not lift to the top of the whole food processor when operating the knob 230 and realizes convenient and labor-saving operation. The above described implementation example only demonstrates several implementation methods of this practical new type. The description is concrete and 5 detailed. But it should not be understood as the limit of the patent scope of this practical new type. It should point out that for the common technicians of this field, they can make several changes and improvements on the condition that the conception and design of this practical new type is followed. Therefore, The attached claim for should prevail for the protection scope for patent of this described practical 10 new type. 11
