Referring to fig. 10 in conjunction with fig. 15 to 17, the main body 1 includes an assembling portion 11 and a connecting arm 12 connected to the assembling portion 11. The connecting arm 12 is provided with a receiving groove 121 extending along the length direction of the connecting arm 12, and the elastic member 3 is located in the receiving groove 121. In the first wall scraping assembly 10 shown in fig. 4 to 7 and the third wall scraping assembly 10 shown in fig. 11 to 14, the accommodating groove 121 may also be provided, that is, the elastic arm 21 is located in the accommodating groove 121, and a skilled person will understand that the connecting member 5 may also be located in the accommodating groove 121. The receiving groove 121 may be formed in any shape, for example, by penetrating the connecting arm 12 in the longitudinal direction of the connecting arm 12, or by a groove extending in the longitudinal direction of the connecting arm 12 and covered with a cover plate to form the receiving groove 121. With such an arrangement, the elastic element 3, or the connecting element 5, or the portion (such as the elastic arm 21) of the wall scraping element 2 connected to the main body 1 is located in the accommodating groove 121, and can be deformed along the length direction of the accommodating groove 121, so that the movement of the wall scraping element 2 can be controlled more easily, and can be abutted to the food material better, and finally, in the embodiment where the wall scraping element 2 is connected to the main body 1 through the connecting element 5, the wall scraping element 2 can be prevented from being too drooped down to collide with the stirring element 201, so that the connecting element can be supported, and the wall scraping element can be abutted to the food material better.

Referring to fig. 15 to 18, the scraping element 2 shown in fig. 15 to 18 is made of an elastic material, and includes an elastic arm 21 and a brush head 22, and the brush head 22 is used for abutting against the food material. In the case where the wall scraping member 2 and the main body 1 shown in fig. 20 and 21 are integrally formed of an elastic material, the main body 1 may be considered to correspond to an elastic arm in such a structure. In both types of wall scraping assemblies 10, the resilient arm 21 or the main body 1 satisfies one or a combination of the following conditions: 1) The thickness is 3mm to 10mm, for example, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.; 2) Shore hardness is 30 degrees to 70 degrees, such as 30 degrees, 32 degrees, 35 degrees, 37 degrees, 40 degrees, 43 degrees, 45 degrees, 48 degrees, 50 degrees, 52 degrees, 55 degrees, 58 degrees, 60 degrees, 62 degrees, 65 degrees, 68 degrees, 70 degrees, and the like; 3) The elastic material is silica gel, and the wall scraping piece 2 is integrally made of silica gel. Further, in the case where the brush head 22 and the elastic arm are not integrally formed, the elastic arm may satisfy the above-described relationship. So set up, the elastic arm 21 or under the condition that the respective thickness of main part 1 is 3mm ~ 10mm, scrape the intensity and the elasticity of wall spare 2 better, it can be insufficient to be too thin can the intensity, for example elastic arm 21 or main part 1 become curved easily and can not be fine make scrape wall spare 2 and eat the material butt. If too thick, the scraping member 2 has a small elastic force and is too costly, and particularly if the elastic force is too small, the scraping member 2 may always rub against the cup wall 401 and cause wear. Under the condition that the shore hardness is 30-70 degrees, the elastic arm 21 or the main body 1 has good elasticity, so that food materials can be scraped better, and the scraping wall part 2 and the cup wall 401 are not abraded due to friction caused by small elasticity due to too hard condition.

Referring to fig. 7 in combination with fig. 4 to 6, and fig. 11 to 14, the main body 1 includes an assembling portion 11 and a connecting arm 12 connected to the assembling portion 11 in an embodiment of the present application. The end of the connecting arm 12 away from the assembling portion 11 is provided with a first limiting portion 122. The wall scraping member 2 is limited by the first limiting portion 122 in the first position, so that the wall scraping member 2 abuts against the food material, for example, the first limiting portion 122 prevents the wall scraping member 2 from rotating, and the limiting is, for example, the wall scraping member 2 from rotating. The skilled person will appreciate that the configuration of the first position-limiting portion 122 is not limited based on the function of the first position-limiting portion 122. So set up, through setting up first spacing portion 122 is spacing so that its butt in cup wall 401 scraping wall spare 2, for example can prevent to scrape wall spare 2 and rotate, and then, the motion stability of scraping wall spare 2 is better, can be better scrape the adhesion in the bold edible material of cup wall 401.

Referring to fig. 7 in conjunction with fig. 4 to 6, and fig. 11 to 14, the first position-limiting portion 122 includes a middle arm 1221, and a first arm 1222 and a second arm 1223 located at two opposite sides of the middle arm 1221, wherein the middle arm 1221, the first arm 1222, and the second arm 1223 enclose an opening 1224. The intermediate arm 1221, the first arm 1222, and the second arm 1223 may have any structures so long as the scraping member 2 is limited and the scraping member 2 abuts against the food material. The scraping element 2 is partly located in the opening 1224 and protrudes through the opening 1224 in the first position. After extending out of the opening 1224, the scraping member 2 can contact the cup wall 401 or be spaced apart from the cup wall 401 by a predetermined distance (e.g., the predetermined distance is less than 3 mm), so as to scrape off the large food materials adhered to the cup wall 401. The protrusion of the wall scraping member 2 from the opening 1224 may be a radial protrusion of the cup 40 or may be a radial protrusion of the cup 40 and an axial (e.g., downward) protrusion of the cup 40 to be limited in view of scraping off a large piece of food. With such an arrangement, the rotation of the wall scraping member 2 is limited by the opening 1224, and the structure for limiting the rotation of the wall scraping member 2 is simple, so that the wall scraping member 2 can better scrape off food materials.

With continuing reference to fig. 7 in conjunction with fig. 4-6, and with further reference to fig. 11-14, the width of the opening 1224 decreases in a direction toward the body 1. With this arrangement, the lateral distance between the wall scraping member 2 and the first arm 1222 and the second arm 1223 is larger and larger in the process of moving from the second position to the first position, so that the wall scraping member 2 can be smoothly moved from the second position to the first position, and the wall scraping member 2 can be better accommodated in the case of returning from the first position to the second position.

The skilled artisan will appreciate that there are various implementations for achieving a gradual increase in the width of the opening 1224 from the second position to the first position, and in fig. 4, 5, 6, and 7, the opening 1224 is V-shaped. The V-shape should be understood broadly, as meaning that the opening 1224 includes two arms that correspond to two sides of a V that meet at a point to form an angle, in this case, the letter V, or the opening 1224 includes two arms that are connected by a rounded corner, in general, the V-shape means that there are two arms like the letter V.

Referring to fig. 11, 12, 13 and 14, fig. 11 to 14 show a third wall scraping assembly 10 according to the present application. The third wall scraping assembly 10 is different from the first wall scraping assembly 10 and the second wall scraping assembly 10 in that the first limiting portion 122 has a different structure, the elastic member 3 may be an elastic cord as in the first wall scraping assembly 10, or a tension spring as in the second wall scraping assembly 10, and therefore, the same reference numerals are used for the components having the same structure or function. The width of the opening 1224 of the first limiting portion 122 of the third wall scraping assembly 10 is gradually reduced from the first position to the main body 1, and the opening 1224 has a trapezoid shape. The third type of wall scraping assembly 10 operates in the same way as the first and second type of wall scraping assemblies 10, still under the effect of centrifugal force, the wall scraping element 2 can be moved from the first position, in which the wall scraping element 2 is in the first position, as shown in fig. 11 and 13, to the second position, in which it is in the second position, as shown in fig. 12 and 14. Furthermore, in the third kind of wall scraping assembly 10, the wall scraping element 2 protrudes through said opening 1224 not only in a lateral direction (which can be considered as being along the length of the connecting arm 12), but also in a vertical direction (perpendicular to the length of the connecting arm 12).

So set up, the V-arrangement is symmetry form or trapezoidal (in the isosceles trapezoid's case), does benefit more to scrape wall part 2 and moves from the first position to the second position or from the second position back to the first position.

The wall scraping assemblies 10 of the embodiments shown in fig. 4 to 14 are all configured to limit the wall scraping member 2 so that the wall scraping member 2 abuts the food material. The skilled person will appreciate that in some embodiments, the purpose of the wall scraping member 2 abutting the foodstuff may also be achieved by limiting the connection between the wall scraping member 2 and the body 1, e.g. limiting the rotation of the resilient arm 21. Such an embodiment will be described below.

Referring to fig. 15, 16, 17 and 18, the main body 1 includes an assembling portion 11 and a connecting arm 12 connected to the assembling portion 11, and the connecting arm 12 is provided with a receiving groove 121 extending along a length direction of the connecting arm 12. The elastic arm 21 is located in the accommodating groove 121. How the elastic arm 21 and the connecting arm 12 are connected is not limited, for example, the elastic arm 21 and the connecting arm 12 may be sleeved, and more specifically, the connecting arm 12 is provided with a mounting post 123, the elastic arm 21 is provided with a mounting hole 32, and the mounting post 123 passes through the mounting hole 32 to realize the sleeving. A limiting mechanism is arranged between the accommodating groove 121 and the elastic arm 21 or the elastic part 3. The limiting mechanism blocks the elastic arm 21 or the elastic element 3 from rotating relative to the connecting arm 12. So set up, because stop gear blocks the elastic arm 21 or the elastic component 3 rotates, and then blocks to scrape wall spare 2 and rotate, and the motion stability of scraping wall spare is better, from this, scrapes that wall spare 2 can be better scrapes off the bold edible material of gluing on cup wall 401. The skilled person will understand that, based on the function of the limiting mechanism, the structure is not limited, and the purpose of preventing the elastic arm 21 from rotating can be achieved. The structures of the stopper mechanisms will be described in detail later. The skilled person will appreciate that the limiting mechanism may also be used in case the resilient arm 21 and the brush head 22 are not integrally provided.

Referring to fig. 18 in combination with fig. 15, 16 and 17, in an embodiment, one of the inner wall of the accommodating groove and the elastic arm 21 or the elastic element 3 is provided with a corner 1211, and the other includes a second limiting portion 211. In the embodiment of the present application, the inner wall of the receiving groove 121 is provided with the corner 1211. The limiting mechanism includes the corner 1211 and the second limiting portion 211, and the second limiting portion 211 is blocked by the corner 1211 to limit the rotation of the elastic arm 21 or the elastic member 3 relative to the connecting arm 12. The configuration of the corner 1211 and the configuration of the second stopper portion 211 are not limited to the rounded corners as shown in the figures, but may be acute, right, obtuse, etc., based on the function of the stopper mechanism, for the purpose of restricting the relative rotation between the elastic arm 21 or the elastic member 3 and the connecting arm 12. In the case where the receiving groove 121 includes the corner 1211, the shape of the cross section of the receiving groove 121 along the direction perpendicular to the length direction of the connecting arm 12 is, for example, a square with rounded corners as shown in the figure, a regular square, other polygons (triangle, regular hexagon, pentagon, etc.), or other irregular shapes.

As an alternative to the above embodiment, it can be understood by the skilled person that at least one section of the accommodating groove 121 and the elastic arm 21 respectively has an oval shape along the cross section perpendicular to the length direction of the accommodating groove 121, and the oval outlines of the two parts constitute the limiting mechanism. That is, in fig. 18, the cross section of the elastic arm 21 is changed from a square shape with rounded corners to an elliptical shape. Of course, the skilled person will understand that the cross section of the whole accommodating groove 121 and the elastic arm 21 may be oval, or the cross section of one of the sections may be oval.

With this arrangement, whether the limiting mechanism includes the corner 1211 and the second limiting portion 211, or the oval contour constitutes the limiting mechanism, the above design prevents the rotation of the wall scraping member 2 with a simple structure on the premise of preventing the rotation of the wall scraping member 2, and in addition, since the corner or the oval contour of this structure does not limit the movement of the wall scraping member 2 along the length direction of the connecting arm 12, it is also ensured that the wall scraping member 2 moves smoothly under the centrifugal force, for example, moves smoothly from the second position to the first position.

Referring to fig. 21 in conjunction with fig. 22, the wall scraping member 2 includes a blocking portion 222 inclined upward in the rotation direction of the body 1, and the blocking portion 222 includes a blocking surface 2221 facing the inside of the cup 40. So set up, because block face 2221 is towards the inside of cup 40, like this, scrape wall spare 2 and can not only scrape off the bold edible material that adheres in cup wall 401, can also prevent to eat the material (these edible materials can be the edible material that does not adhere in cup wall 401 in the cup, also can be by the edible material of scraping) upward movement, further make to eat the material thickness even. The skilled person will understand that in the case of two or more scraping members 2, the blocking surface 2221 of each scraping member 2 faces the inside of the cup body 40. Although the scraping member 2 has been described as including the blocking portion 222 in the form of an integral part of the scraping member 2 with the main body 1, the skilled person will appreciate that the scraping member 2 may also include the blocking portion 222 in other scraping assemblies, such as the scraping assembly 10 shown in fig. 1 to 14.

The configuration of the stop surface 2221 is not limited based on the function of the stop surface 2221, and in some embodiments, the stop surface 2221 is an inclined surface, or the stop surface 2221 includes an arched surface that is curved in a direction opposite to the rotation direction, as shown in fig. 22, the rotation direction of the stirring assembly 20 is A1, the rotation direction of the corresponding body 1 is A1, and the stop surface 2221 is curved outward (in a direction A2 shown in fig. 22) to form the arched surface (relative to the inside of the cup body 40, the surface facing the inside of the cup body 40 is referred to as an inner surface, and the surface facing away from the inside of the cup body 40 is an outer surface), and accordingly, the stop portion 222 includes an arch 2220 as viewed from the outer surface. So set up, scrape wall subassembly 10's simple structure, the shape is pleasing to the eye, moreover, the arched surface that the bending is makes and scrapes wall spare part and do not have gap or dead angle, is convenient for wash and scrapes wall subassembly 10, especially, scrapes under the condition of wall spare and the integrative structure of main part, is more convenient for wash and scrapes wall subassembly 10.

The food processor comprises any one of the wall scraping assemblies 10, the stirring assembly 20 and the motor driving device 301. Specifically, the food processor includes a head assembly 30. The handpiece assembly 30 includes the motor drive 301. The main body of the wall scraping assembly 10 and the stirring assembly 20 are both driven by the motor driving device 301. For example, the assembly portion 11 of the main body 1 and the rotation shaft 202 of the stirring unit 20 are inserted so as to be coaxial with each other. The wall scraping component 10 and the stirring component 20 are driven by the motor driving device 301 to rotate in the cup body 40 at the same rotating speed, and the wall scraping component 2 scrapes off the food materials adhered to the cup wall 401 of the cup body 40. Except for the case that the wall scraping assembly 10 and the stirring assembly 20 rotate at the same speed, the wall scraping assembly 10 and the stirring assembly 20 are driven by the motor driving device 301 to rotate at different speeds, for example, the main body 1 is connected to the motor driving device 301 through a speed reducing mechanism, and the rotating shaft 202 of the stirring assembly 20 is directly connected to the motor driving device 301, so that the stirring assembly 20 and the wall scraping assembly 10 are driven by the motor driving device 301 to rotate, the rotating speed of the stirring assembly 20 is equal to the rotating speed of the motor driving device 301, and the rotating speed of the wall scraping assembly 10 is different from the rotating speed of the motor driving device 301. So set up, improve the flexibility of control.

The structure of the main body driving device 4 and the motor driving device 301 is not limited as to how they are assembled to the food processor.

As will be further described below in conjunction with the drawings, the wall scraping assembly 10 and the stirring assembly 20 are driven together by the motor driving device 301 or independently driven.

With continuing reference to fig. 2, 3, 8, 9 and 21, the food processor includes a cover 50 and a head assembly 30 having the motor driving device 301. The head assembly 30 and the cover 50 are assembled in a separable manner, the separable assembly means that the head assembly 30 is assembled on the cover 50 when the food processor needs to work, and the head assembly 30 is separated from the cover 50 when the food processor does not need to work. The main body 1 is assembled to the stirring assembly 20, and more specifically, to the rotating shaft 202 of the stirring assembly 20, and the stirring element 201 of the stirring assembly 20 is also assembled to the rotating shaft 202, so that the motor driving device 301 drives the rotating shaft 202 to rotate to drive the stirring element 201 and the wall scraping element 2 to rotate together. In the above embodiment, it can be understood by the skilled person that the main body 1 can be mounted on the cover 50, and in this case, how the main body 1 is mounted on the cover 50 and how the wall scraping member 2 abuts against the food material of the cup wall 401 can be in various manners, for example, the connecting arm 12 of the main body 1 is not located in the horizontal direction as in fig. 4, 5, 6 or 8, and can be inclined downward with respect to the assembling portion 11. In some embodiments, the wall scraping assembly 10 may also be assembled to the head assembly 30, and any structure may be adopted for how to assemble the wall scraping assembly 10, so that the wall scraping member 2 of the wall scraping assembly 10 can perform the corresponding function; in other embodiments, the main body 1 is assembled with the cover 50 and the stirring assembly 20.

The stirring assembly 20 and the wall scraping assembly 10 are driven independently, and there are at least two embodiments, in the first embodiment, the main body driving device 4 is disposed on the cover 50, the motor driving device 301 is disposed on the head assembly 30, after the cover 50 is covered on the cup 40 and the head assembly 30 is disposed on the cover 50, the motor driving device 301 is connected to the rotating shaft 202 to drive the stirring assembly 20 to rotate, and the main body driving device 4 drives the wall scraping assembly 10 to rotate.

2. Construction of wall scraping assembly in non-centrifugal mode

The structure of the wall scraping assembly 10 of the non-centrifugal mode may be the same as that of the wall scraping assembly 10 of the centrifugal mode, because the centrifugal mode is to make the wall scraping member 2 away from the main body 1 and abut against the food material by centrifugal force, and the non-centrifugal mode is to make the wall scraping member 2 move towards the main body 1 and abut against the food material, taking as an example that the wall scraping member 2 is connected to the main body 1 through an elastic member, in the case of the centrifugal mode, the elastic member extends, and in the case of the non-centrifugal mode, the elastic member is compressed, and similarly, if the wall scraping member 2 is connected with the main body 1 through a telescopic mechanism, in the case of the centrifugal mode, the telescopic mechanism extends, and in the case of the non-centrifugal mode, the telescopic mechanism shortens. In the following, two embodiments will be described to make the present application more clear and understandable.

Referring to fig. 24 to 27, the wall scraping assembly 10 shown in fig. 24 to 27 may have the same structure as the wall scraping assembly 10 described above. The wall scraping assembly 10 of the embodiment shown in fig. 24 to 27 can be combined with the wall scraping assembly 10 shown in fig. 10. The wall scraping assembly 10 comprises a wall scraping member 2 and a main body 1. The body 1 also includes receiving grooves 121 and the like. The scraping member 2 is connected with the main body 1 through an elastic member 3. The elastic member 3 is a spring, but may be other members capable of generating elastic deformation, for example, the elastic member 3 may be made of an elastic material. In this kind of wall scraping assembly 10, the relevant dimensions of the wall scraping member 2 also satisfy the above-mentioned D1, D2, D3 and D4, and other structural similarities will not be described again.

Referring to fig. 28 and 29, the related structure of the wall scraping assembly 10 corresponding to fig. 28 and 29 can be seen from the related structure of the wall scraping assembly 10 shown in fig. 15 to 18, for example, in the eighth wall scraping assembly 10 shown in fig. 28 and 29, the wall scraping member 2 is an elastic member including an elastic arm 21.

Referring to fig. 27 and 29 and fig. 24 to 26 and 28, the process of scraping the large food material by the wall scraping assembly 10 is described as follows:

after the assembly of the scraping assembly 10 and the stirring assembly 20, the scraping member 2 moves toward the body 1 to abut against the cup wall 401, for example, the elastic member 3 is compressed to abut against the cup wall 401. Subsequently, the motor driving device 301 rotates to drive the stirring assembly 20 and the wall scraping member 2 to rotate together, and the wall scraping member 2 rotates to scrape off the food adhered to the cup wall 401.

Although the non-centrifugal method is described as two embodiments, the wall scraping assembly 10 scrapes off the food adhered to the cup wall 401, but the skilled person will understand that the difference is that the method for abutting the wall scraping member 2 with the food is different from the centrifugal method, and therefore, in the non-centrifugal method, including the centrifugal method, other methods of scraping the wall scraping member 2, for example, the wall scraping assembly 10 and the stirring assembly 20 are driven by the motor driving device 301 together, or the non-centrifugal method can be realized by the wall scraping assembly 10 shown in fig. 20, in which case, the wall scraping member 2 and the main body 1 are integrally formed, and the wall scraping member 2 is compressed to abut with the food; for another example, the arrangement of the first stopper portion 122, the stopper mechanism, and the like may be applied to a non-centrifugal embodiment, in which the width of the opening decreases in the direction toward the main body, and the advantageous effects are as follows: the wall scraping piece is compressed to move towards the main body, and the wall scraping piece is more convenient to limit along the direction of the main body. In non-centrifugal embodiments, the V-shaped or trapezoidal opening further facilitates the wall scraping element to be restrained.

In the non-centrifugal mode, the motion trail of the scraping member 2 can also adopt the motion trail in the centrifugal mode, because the scraping member assembly 10 and the stirring assembly 20 are driven by the motor driving device 301 together.

In the above various embodiments, only one of the main body driving device 4 and the motor driving device 301 is provided, and the structure of the wall scraping assembly 10 is combined (for example, the wall scraping member 2 abuts against the food material due to centrifugal force, and the wall scraping member 2 is compressed in the non-centrifugal case), so that the structure of the wall scraping assembly 10 is simple (especially, in the case that the main body 1 and the wall scraping member 2 are integrally formed), the occupied space is small, and the structure of the food processor is simple.

The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not to be construed as limiting the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present application should be included in the scope of the present application.
