Description

TECHNICAL FIELD

[0001] The utility model relates to life electric appliance technical field, concretely relates to a food processor with stable structure. BACKGROUND

[0002] The existing food processor such as meat grinder, dough mixer etc. usually includes cup body with built-in stirring knife and main machine set above cup body, main machine is equipped with motor with stirring knife transmission connection, user places food material in cup body when using food processor, stirring knife rotates under the drive of motor to realize the processing of food material. The stirring knife needs to be positioned when fixed in cup body to ensure that stirring knife can rotate normally, the existing positioning mode of stirring knife such as the top end of the stirring knife shaft in Chinese patent CN200720056746. X, CN201520247250. 5 is engaged to realize the positioning of top end through the upper connecting head connected with motor, at the same time, the limiting column extending downward is set at the bottom end of the shaft, the limiting slot is set on the bottom wall of cup body to realize the limiting of bottom end of stirring knife, so as to realize the positioning of the whole stirring knife through the limiting of top end and bottom end. But the limiting slot set at the bottom end of the stirring knife shaft or cup body is usually deep, at the same time, in order to leave larger crushing space in cup body, and the comprehensive consideration of the cost and weight of the shaft, so the diameter of the shaft itself cannot be made very wide, which leads to the diameter of the limiting slot in the shaft is relatively narrow between 5mm and 8mm, further leading to the limiting slot not only deep but also narrow, part of food material slurry etc. enters into the limiting slot during food processing, which is difficult to clean for user, and long-term cleaning not in place will lead to the generation of peculiar smell or mildew in the limiting slot, and user cannot continue to use.

[0003] In order to solve the above-mentioned problem of difficult cleaning of the inside of the cutter shaft, some researchers first think of setting a groove on the inner bottom surface of the cup body, and setting a protruding column at the bottom of the cutter shaft which is inserted into the groove. Then, in order to improve the stability of this installation method, some researchers change the protruding column into a magnetic attraction piece such as a magnet, and set a matching piece on the cup body which can be magnetically attracted to the magnetic attraction piece, so as to realize the positioning of the bottom of the cutter shaft and the whole stirring knife by means of the magnetic attraction force between the magnetic attraction piece and the matching piece, thereby eliminating the structure of opening a limiting groove in the cutter shaft and setting a limiting shaft in the cup body, and facilitating the user to clean the cup body and the stirring knife. In order to facilitate the installation of the matching piece matched with the magnet, and at the same time avoid the contact between the matching piece and the food material, the matching piece is usually adhesively installed on the outer bottom surface of the cup body. The matching piece is exposed to the outside for a long time and will cause serious aging of the adhesive when processing relatively hot food materials, thereby causing the matching piece to be separated from the cup body and the magnetic attraction piece to be unable to be attracted to the matching piece, thereby causing poor or even ineffective limiting of the cutter shaft. Moreover, since the matching piece is adhered to the outer bottom surface of the cup body, the magnetic attraction piece is far away from the matching piece, and the magnetic attraction force between the two will be greatly reduced. One method is to use a magnet with high magnetic attraction force, but this will inevitably lead to an increase in cost. Another method is to make the bottom wall of the cup body thin, especially the wall thickness of the region where the matching piece is installed. This region is the most stressed region, which will cause the cup body to be easily damaged and deformed when subjected to a large impact, thereby seriously affecting the consumer experience. Practical new type content

[0004] The purpose of the present application is to provide a food processor with stable structure, which solves the problem that the matching piece matched with the magnetic attraction piece at the bottom of the cutter shaft is installed on the outer bottom surface of the cup body in the existing food processor, and the matching piece is easily separated from the cup body and the magnetic attraction force between the magnetic attraction piece and the matching piece is small.

[0005] To achieve the above-mentioned purpose, the present application provides a food processor with stable structure, which comprises a cup body with an internal stirring knife and a main machine arranged above the cup body. The main machine is internally provided with a motor in transmission connection with the stirring knife. The stirring knife comprises a cutter shaft. The inner bottom surface of the cup body is provided with an installation groove in plug-in cooperation with the bottom of the cutter shaft. The bottom of the cutter shaft is provided with a first magnetic attraction piece. The installation groove is provided with a second magnetic attraction piece in magnetic attraction cooperation with the first magnetic attraction piece.

[0006] The application is characterized in that a mounting groove is arranged on the inner bottom surface of the cup body, the mounting groove is in plug-in cooperation with the bottom of the blade shaft, and after the user installs the stirring blade in place, the mounting groove limits the bottom of the blade shaft in the radial direction, thereby ensuring the stability of the position of the stirring blade. Meanwhile, the bottom of the blade shaft is provided with a first magnetic attraction element, the cup body is provided with a second magnetic attraction element in magnetic attraction cooperation with the first magnetic attraction element, and the magnetic attraction cooperation between the first magnetic attraction element and the second magnetic attraction element further realizes the limiting effect, thereby further ensuring the stability of the limiting cooperation between the stirring blade and the mounting groove. In addition, with the large radial cooperation size of the blade shaft and the mounting groove, the user can conveniently clean the mounting groove, avoid the situation that the residual food materials in the mounting groove are prone to odor or even mold due to the difficulty in cleaning the mounting groove, and improve the user experience.

[0007] Meanwhile, the second magnetic attraction element is arranged at the mounting groove, and the second magnetic attraction element can be arranged in two ways, one of which is arranged in the mounting groove, and the other of which is integrally formed in the bottom wall of the mounting groove, thereby protecting the second magnetic attraction element. Therefore, compared with the existing arrangement mode of arranging the second magnetic attraction element on the outer bottom surface of the cup bottom, on the one hand, the second magnetic attraction element is effectively prevented from being easily separated from the cup body due to the serious adhesion aging of the second magnetic attraction element caused by the long-term exposure of the second magnetic attraction element to the outside and the high temperature of the cup body, thereby preventing the first magnetic attraction element and the second magnetic attraction element from being unable to be attracted to realize the limiting of the blade shaft. On the other hand, the first magnetic attraction element and the second magnetic attraction element are prevented from being far away from each other, thereby preventing the magnetic attraction force of the two from being weak, causing the limiting effect of the blade shaft to be poor, and further causing the blade shaft to swing or even interrupt the processing when rotating, thereby ensuring the stability of the food processing.

[0008] In a preferred implementation mode of the food processor with stable structure, the second magnetic attraction element is fixedly arranged on the bottom wall of the mounting groove, and the second magnetic attraction element is arranged separately from the first magnetic attraction element.

[0009] By fixing the second magnetic attraction element on the bottom wall of the mounting groove and arranging the second magnetic attraction element separately from the first magnetic attraction element, the second magnetic attraction element can be fixedly arranged while avoiding mutual contact with the first magnetic attraction element, thereby preventing the first magnetic attraction element and the second magnetic attraction element from having too large an attraction force, causing the stirring blade to generate a large friction noise with the second magnetic attraction element when rotating, and preventing the user from needing a large force to take the cup body when the stirring blade is taken, thereby ensuring the stability of the rotation of the stirring blade and improving the user experience.

[0010] In a preferred implementation mode of the food processor with stable structure, a wear-resistant gasket is arranged between the first magnetic attraction element and the second magnetic attraction element to separate the two.

[0011] By providing a wear-resistant gasket between the first magnetic attraction member and the second magnetic attraction member, the first magnetic attraction member and the second magnetic attraction member are separated by the wear-resistant gasket, and the second magnetic attraction member can be isolated from the crushing cavity by the wear-resistant gasket, thereby avoiding the penetration of food materials between the second magnetic attraction member and the mounting groove, causing residual food materials between the two and being unable to be effectively cleaned, resulting in odor or even mold in this area, and ensuring the cleanliness of the cup body.

[0012] In a preferred implementation of a structurally stable food processor, the wear-resistant gasket is clamped in the mounting groove, and the wear-resistant gasket is provided with a limiting groove on the side facing the second magnetic attraction member, and the second magnetic attraction member is fixed between the limiting groove and the bottom wall of the mounting groove; or,

[0013] The bottom wall of the knife shaft abuts against the top wall of the wear-resistant gasket.

[0014] By clamping the wear-resistant gasket in the mounting groove, and providing a limiting groove on the side of the wear-resistant gasket facing the second magnetic attraction member, and fixing the second magnetic attraction member between the limiting groove and the bottom wall of the mounting groove, the fixation of the second magnetic attraction member is achieved, further improving the stability of the position of the second magnetic attraction member, avoiding displacement of the second magnetic attraction member, causing axial misalignment of the second magnetic attraction member and the first magnetic attraction member, and further weakening the magnetic attraction force between the first magnetic attraction member and the second magnetic attraction member.

[0015] By setting the bottom wall of the knife shaft to abut against the top wall of the wear-resistant gasket, the axial support of the knife shaft is achieved, and the separate structure of the knife shaft and the second magnetic attraction member is omitted, which helps to simplify the structure of the stirring knife and reduce production costs.

[0016] In a preferred implementation of a structurally stable food processor, the mounting groove includes a first mounting groove and a second mounting groove with a reduced inner diameter relative to the first mounting groove, and the second magnetic attraction member is completely embedded in the second mounting groove.

[0017] By setting the mounting groove to include a first mounting groove and a second mounting groove with a reduced inner diameter relative to the first mounting groove, and embedding the second magnetic attraction member in the second mounting groove, the second magnetic attraction member can be directly embedded and fixed in the second mounting groove, thereby improving the stability of the second magnetic attraction member, and the second mounting groove can also limit the second magnetic attraction member in the radial direction, further improving the stability of the position of the second magnetic attraction member.

[0018] In a preferred implementation of a structurally stable food processor, the bottom of the knife shaft is lapped on the top wall of the second mounting groove.

[0019] By setting the bottom of the knife shaft to lap on the top wall of the second mounting groove, the bottom of the knife shaft can be limited in a higher range of the mounting groove, thereby further improving the stability of the rotation of the knife shaft.

[0020] In the preferred implementation of the food processor with stable structure, the second magnetic member is integrally injection molded with the cup body, and is located below the mounting groove.

[0021] By setting the second magnetic member to be integrally injection molded with the cup body, the step of fixing the second magnetic member with the cup body is omitted, and the structure is simplified, which helps to improve the assembly efficiency.

DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail in conjunction with the accompanying drawings.

[0036] It should be noted that in the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0037] As shown in Figures 1 to 6 The present application provides a food processor with stable structure, which comprises a cup body 3 with a built-in stirring knife 4 and a main machine 1 arranged above the cup body 3, wherein the main machine 1 is internally provided with a motor 2 in transmission connection with the stirring knife 4, the stirring knife 4 comprises a knife shaft 41, the inner bottom surface of the cup body 3 is provided with a mounting groove 31, the mounting groove 31 is in plug-in fit with the bottom of the knife shaft 41, the bottom of the knife shaft 41 is provided with a first magnetic attraction piece 5, and the mounting groove 31 is provided with a second magnetic attraction piece 6 in magnetic attraction fit with the first magnetic attraction piece 5.

[0038] The present application is provided with the mounting groove 31 on the inner bottom surface of the cup body 3, and the mounting groove 31 is in plug-in fit with the bottom of the knife shaft 41, so that after the user installs the stirring knife 4 in place, the mounting groove 31 realizes radial limiting of the bottom of the knife shaft 41, thereby ensuring the stability of the position of the stirring knife 4. Meanwhile, the bottom of the knife shaft 41 is provided with the first magnetic attraction piece 5, and the cup body 3 is provided with the second magnetic attraction piece 6 in magnetic attraction fit with the first magnetic attraction piece 5, and the magnetic attraction fit of the first magnetic attraction piece 5 and the second magnetic attraction piece 6 further realizes limiting effect, which can further ensure the stability of the limiting fit of the stirring knife 4 and the mounting groove 31. In addition, with the large radial fit size of the knife shaft 41 and the mounting groove 31, the user can conveniently clean the mounting groove 31, thereby avoiding the situation that the mounting groove 31 is difficult to clean, the residual food materials inside the mounting groove 31 are prone to produce odor or even mildew, and the user experience is improved.

[0039] Meanwhile, the second magnetic attraction member 6 is arranged at the mounting groove 31. The second magnetic attraction member 6 can be arranged in two ways, one of which is arranged in the mounting groove 31, and the other of which is integrally formed in the bottom wall of the mounting groove 31 to protect the second magnetic attraction member 6. Therefore, compared with the existing arrangement of the second magnetic attraction member 6 arranged on the outer bottom surface of the cup bottom, on the one hand, the second magnetic attraction member 6 is effectively prevented from being easily separated from the cup body 3 due to serious aging of the adhesive caused by long-term exposure of the second magnetic attraction member 6 to the outside and high temperature of the cup body 3, thereby causing the first magnetic attraction member 5 and the second magnetic attraction member 6 to be unable to be attracted to limit the cutter shaft 41. On the other hand, the first magnetic attraction member 5 and the second magnetic attraction member 6 are prevented from being too far away from each other to cause the magnetic attraction force of the two to be too weak, thereby causing the limiting effect on the cutter shaft 41 to be poor, and further causing the cutter shaft 41 to swing or even interrupt the processing when rotating, thereby ensuring the stability of the food processing.

[0040] It should be noted that the application does not specifically limit the arrangement position of the second magnetic attraction member 6, which can be any one of the following embodiments:

[0041] Embodiment 1: As shown in the embodiment, the second magnetic attraction member 6 is fixedly arranged on the bottom wall of the mounting groove 31, and the second magnetic attraction member 6 is arranged separately from the first magnetic attraction member 5. Figure 2

[0042] By fixing the second magnetic attraction member 6 on the bottom wall of the mounting groove 31 and arranging the second magnetic attraction member 6 separately from the first magnetic attraction member 5, the second magnetic attraction member 6 can be fixedly arranged while avoiding mutual contact with the first magnetic attraction member 5, thereby preventing the first magnetic attraction member 5 and the second magnetic attraction member 6 from having too large an attraction force to cause the stirring knife 4 to generate a large friction noise with the second magnetic attraction member 6 when rotating. At the same time, the application avoids the situation that the user needs to exert a large force to take the stirring knife 4 from the cup body 3 due to the too large attraction force between the two, thereby ensuring the stability of the stirring knife 4 in rotation and improving the user experience.

[0043] It should be further noted that the application does not specifically limit how the first magnetic attraction member 5 and the second magnetic attraction member 6 are separated in this embodiment, which can be any one of the following implementation manners:

[0044] Implementation manner 1: As shown in the embodiment, a wear-resistant gasket 7 is arranged between the first magnetic attraction member 5 and the second magnetic attraction member 6 to separate the two. Figure 2

[0045] ​​By providing the wear-resistant pad 7 between the first magnetic attraction piece 5 and the second magnetic attraction piece 6, the first magnetic attraction piece 5 and the second magnetic attraction piece 6 are separated by the wear-resistant pad 7, and the second magnetic attraction piece 6 can be isolated from the crushing cavity by the wear-resistant pad 7, thereby avoiding the penetration of food materials between the second magnetic attraction piece 6 and the mounting groove 31, causing residual food materials between the two and being unable to be effectively cleaned, resulting in odor or even mold at this location, and ensuring the cleanliness of the cup body 3.

[0046] Further, as shown in Figure 2 , the wear-resistant pad 7 is clamped in the mounting groove 31, and the wear-resistant pad 7 is provided with a limiting groove 71 on the side facing the second magnetic attraction piece 6, and the second magnetic attraction piece 6 is fixed between the limiting groove 71 and the bottom wall of the mounting groove 31.

[0047] By clamping the wear-resistant pad 7 in the mounting groove 31, and providing the wear-resistant pad 7 with a limiting groove 71 on the side facing the second magnetic attraction piece 6, and fixing the second magnetic attraction piece 6 between the limiting groove 71 and the bottom wall of the mounting groove 31, the second magnetic attraction piece 6 is fixed, further improving the stability of the position of the second magnetic attraction piece 6, avoiding displacement of the second magnetic attraction piece 6, causing the second magnetic attraction piece 6 and the first magnetic attraction piece 5 to be axially misaligned, and thereby causing the magnetic attraction force of the first magnetic attraction piece 5 and the second magnetic attraction piece 6 to weaken.

[0048] It should be noted that the present application does not specifically limit the relative relationship between the knife shaft 41 and the wear-resistant pad 7 in this embodiment, and preferably, as shown in Figure 2 , the bottom wall of the knife shaft 41 abuts against the top wall of the wear-resistant pad 7.

[0049] By setting the bottom wall of the knife shaft 41 to abut against the top wall of the wear-resistant pad 7, the axial support of the knife shaft 41 is achieved, and the separate structure of the knife shaft 41 from the second magnetic attraction piece 6 is omitted, which helps to simplify the structure of the stirring knife 4 and reduce production costs.

[0050] Embodiment 2: As shown in Figure 3 , Figure 4 , in this embodiment, the surface of the second magnetic attraction piece 6 is wrapped with glue 8 to fix the second magnetic attraction piece 6 to the bottom wall of the mounting groove 31 and separate the first magnetic attraction piece 5 and the second magnetic attraction piece 6.

[0051] Embodiment 3: As shown in Figure 4 , in this embodiment, the side wall of the knife shaft 41 is provided with a positioning part lapping the slot opening of the mounting groove 31, and the distance between the bottom wall of the positioning part and the bottom wall of the knife shaft 41 is less than the distance between the top wall of the mounting groove 31 and the second magnetic attraction piece 6, so as to separate the two.

[0052] It should be noted that this application does not specifically limit the structure of the positioning part in this embodiment. It can be that the cutter shaft 41 includes a cutter shaft 41 body and a positioning shaft provided below the cutter shaft 41 body. The positioning shaft is inserted into the mounting groove 31. The outer diameter of the positioning shaft is reduced relative to the outer diameter of the cutter shaft 41 body to form a step portion with the step surface 412 facing downward. The step surface 412 is the positioning part. Alternatively, the side wall of the cutter shaft 41 is provided with an outwardly extending flange. The flange overlaps the groove opening of the mounting groove 31. The flange is the positioning part.

[0053] Example 2: As Figure 2 , Figure 5 , Figure 6 As shown, in this embodiment, the mounting groove 31 includes a first mounting groove 312 and a second mounting groove 311 with a smaller inner diameter than the first mounting groove 312, and the second magnetic member 6 is completely embedded in the second mounting groove 311.

[0054] By setting the mounting groove 31 to include a first mounting groove 312 and a second mounting groove 311 with a smaller inner diameter than the first mounting groove 312, the second magnetic member 6 is completely embedded in the second mounting groove 311, so that the second magnetic member 6 can be directly embedded and fixed in the second mounting groove 311, thereby improving the stability of the second magnetic member 6. At the same time, the second mounting groove 311 can also limit the second magnetic member 6 radially, further improving the positional stability of the second magnetic member 6.

[0055] It should be noted that this application does not specifically limit the forming method of the second mounting groove 311, such as... Figure 6 As shown, it can be that the bottom wall portion of the first mounting groove 312 is recessed and radially narrowed to form the second mounting groove 311; as Figure 2 As shown, the bottom wall of the first mounting groove 312 can also form an upwardly protruding ring to form a second mounting groove 311 within the protruding ring, which will not be described in detail here.

[0056] Furthermore, such as Figure 6 As shown, the bottom of the cutter shaft 41 is attached to the top wall of the second mounting groove 311.

[0057] By setting the bottom of the cutter shaft 41 to overlap the top wall of the second mounting groove 311, the bottom of the cutter shaft 41 can achieve a higher range of positioning relative to the mounting groove 31, thereby further improving the stability of the rotation of the cutter shaft 41.

[0058] Example 3: In this example, the second magnetic component 6 is integrally injection molded with the cup body 3, and the second magnetic component 6 is located below the mounting groove 31.

[0059] By making the second magnetic chuck 6 integrally injection molded with the cup body 3, the steps and structures for fixing the second magnetic chuck 6 to the cup body 3 are eliminated, which helps to improve assembly efficiency. At the same time, the second magnetic chuck 6 is fixed inside the cup body 3 and its position cannot be moved, thus effectively improving the stability of the position of the second magnetic chuck 6. It also ensures the alignment of the second magnetic chuck 6 with the mounting groove 31, thereby ensuring the magnetic attraction between the first magnetic chuck 5 and the second magnetic chuck 6 when they are engaged, and further enhancing the limiting effect on the cutter shaft 41.

[0060] In a preferred embodiment of this application, the second magnetic member 6 is disposed around the side wall of the mounting groove 31.

[0061] By setting the second magnetic suction member 6 to surround the side wall of the mounting groove 31, the second magnetic suction member 6 can reduce the axial height occupied by the mounting groove 31, thereby greatly increasing the depth of the blade shaft 41 inserted into the mounting groove 31, which can further improve the insertion and engagement stability of the blade shaft 41 and the mounting groove 31, and improve the rotational stability of the entire stirring blade 4.

[0062] It should be noted that this application does not specifically limit the fixing method of the first magnetic member 5. As a preferred embodiment of this application, such as Figure 2 As shown, the cutter shaft 41 has a hollow cavity 411 with an open bottom, and the first magnetic attractor 5 is fixed inside the hollow cavity 411.

[0063] By providing a hollow cavity 411 with an internal hollow structure and an open bottom on the cutter shaft 41, and fixing the first magnetic suction member 5 inside the hollow cavity 411, the first magnetic suction member 5 can be installed and fixed, while also facilitating the demolding of the cutter shaft 41. This helps to reduce the overall weight of the cutter shaft 41, making its rotation easier. It also reduces the weight of the entire machine, making it easier for users to pick up and put down the machine. Furthermore, it reduces the amount of material used for demolding the cutter shaft 41, thereby reducing production costs. Additionally, it ensures that the side wall thickness of the cutter shaft 41 is uniform, guaranteeing the stability of the stirring blade 4 during rotation and preventing the entire cutter shaft 41 from being solid, which would result in a slower cooling rate after injection molding and thus reduce production efficiency.

[0064] As a preferred embodiment of this application, such as Figure 2 As shown, the second magnetic component 6 is aligned with the mounting groove 31.

[0065] By aligning the second magnetic 6 with the mounting groove 31, the first magnetic 5 and the second magnetic 6 can be aligned and attracted after the cutter shaft 41 is inserted into the mounting groove 31, thereby ensuring the attraction force of the first magnetic 5 and the second magnetic 6 after magnetic attraction, and further enhancing the limiting effect on the cutter shaft 41.

[0066] The technical scheme of the utility model is not limited to the above embodiment, it should be pointed out that the technical scheme of any one embodiment is combined with the technical scheme of one or more other embodiments, and is within the protection scope of the utility model. Although the utility model has been described in detail by general description and specific embodiments in the above, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model all belong to the range of the utility model required to be protected.
