Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] Existing food processing machines typically use blades to pulverize food ingredients. For example, existing technology discloses a blade assembly and a food processor. The blade assembly includes: a support base; a rotating shaft rotatably mounted on the support base; a driven disk fixedly connected to one end of the rotating shaft extending from the support base; and a housing, which is cylindrical with one end closed and the other open. The support base closes the housing to form a sealed cavity, and the driven disk is located within the sealed cavity. The support base is connected to the housing. The driven disk includes a bracket and a magnetic component mounted circumferentially on the bracket. The magnetic component in the driven disk is a permanent magnet. A motor capable of forward and reverse rotation is located in the base, and the driven disk is positioned at the end of the motor's output shaft. This design allows the blade assembly to be removed entirely from the mixing cup, making blade cleaning and replacement more convenient.

[0003] However, after cleaning the mixing cup, residual water remains on the bottom wall. If this residual water is not evaporated before installing the blade assembly, it can splash upwards along the gap between the blade assembly and the side wall of the mixing blade, potentially hitting the user's arm or splashing out of the mixing cup. Conversely, reducing this gap can cause the blade assembly's support to interfere with the inner wall of the mixing cup during installation, leading to jamming. Furthermore, the support divides the mixing cup's interior into a lower chamber near the bottom wall and an upper chamber above it. Due to the small gap, the lower chamber tends to become more enclosed as the blade assembly approaches the bottom wall, creating a negative pressure in the lower chamber and a significant pressure difference with the upper chamber after the support is in place, making subsequent disassembly of the blade assembly difficult. Utility Model Content

[0004] This utility model provides a food processing machine, which solves the problem that residual water in the mixing cup will splash upward from the gap between the blade holder and the mixing cup during the installation of the blade assembly, and that reducing the gap will make the blade assembly difficult to disassemble and assemble.

[0005] The technical solution adopted by this utility model is as follows: This utility model provides a food processing machine, including a main unit, a mixing cup installed on the main unit, and a blade assembly detachably installed in the mixing cup. The blade assembly includes a blade holder, a transmission disk rotatably installed in the blade holder, a mixing blade located above the blade holder, and a transmission shaft passing through the blade holder to connect the transmission disk and the mixing blade. The main unit is provided with a motor and a drive disk driven by the motor. The drive disk drives the transmission disk to rotate in the air. The bottom of the mixing cup is provided with a downwardly recessed groove. The blade holder includes a mating part that is inserted into the groove and radially limited by the groove. An exhaust channel is provided between the mating part and the side wall of the groove. The blade holder also includes a blocking part that protrudes radially outward relative to the top of the mating part to block the exhaust channel.

[0006] This invention provides a food processing machine that features a settling groove at the bottom of the mixing cup. The blade holder includes a mating part that radially limits its movement within the settling groove, ensuring reliable positioning of the blade holder within the mixing cup after installation and achieving stable operation of the mixing blade. The venting channel provides clearance between the mating part of the blade holder and the side wall of the settling groove, preventing interference and collisions during blade assembly installation, thus facilitating installation. Furthermore, by providing a shielding part that protrudes radially outward from the top of the mating part, even if residual water remains in the mixing cup, it is blocked by the shielding part when the user places the blade assembly, preventing further splashing onto the user's arm or outside the mixing cup, effectively solving the problem of residual water splashing. Furthermore, without adjusting the size of the exhaust channel, the blade holder divides the inner cavity of the mixing cup into a lower chamber located in the settling tank and an upper chamber located above the lower chamber. After the blade assembly is installed, the exhaust channel design ensures that the air pressure in the upper and lower chambers is balanced. Therefore, when the user needs to remove the blade assembly, the lower chamber will not exert too much suction on the blade holder, thus avoiding the problem of difficult blade removal and enabling easy disassembly of the blade assembly. In summary, this application, through the cooperation of the exhaust channel and the shield, not only prevents residual water from splashing onto the user's arm and outside the mixing cup, but also achieves easy installation and removal of the blade assembly.

[0007] Furthermore, since the bottom of the mixing cup has a downwardly recessed groove, the blade holder includes a mating part that inserts into the groove and radially limits it. The mating part and the groove radially limit the blade holder. Because the shielding part protrudes radially outward relative to the top of the mating part, if large particles of food on the blade tip cause the blade holder to tilt, the shielding part can preferentially contact the inner wall of the mixing cup. Combined with the mating part's engagement with the side wall of the groove, this achieves a straightening effect on the blade holder, preventing it from detaching from the groove and effectively preventing the transmission disk from exceeding the driving range of the drive disk. Therefore, the transmission is reliable, and the blade assembly operates stably. Correspondingly, the drive disk can be exposed on the top of the main unit and close to the bottom of the mixing cup to be near the transmission disk; alternatively, the drive disk can be completely enclosed inside the main unit and driven remotely from the transmission disk. This eliminates any rotatable components on the outside of the main unit, making it safer to use.

[0008] In a preferred embodiment, the top of the sidewall of the settling tank is connected to a guide wall that extends gradually outward from bottom to top, and the shielding portion overlaps with the guide wall in the transverse direction.

[0009] By connecting a guide wall that extends gradually outward from bottom to top to the top of the side wall of the settling tank, the shielding part and the guide wall overlap laterally. If there is residual water in the stirring cup, its splashing path is as follows: the residual water splashes upward along the exhaust channel, changes its splashing direction after being blocked by the shielding part, and splashes towards the guide wall. When the residual water splashes onto the guide wall, it will flow upward or downward along the guide wall due to inertia, and will not splash onto the user's arm, and it is also difficult for it to splash out of the stirring cup.

[0010] In a preferred embodiment, the shielding portion is folded outward from the top of the mating portion, and an arc-shaped transition surface is provided at the connection position between the shielding portion and the mating portion.

[0011] By providing an arc-shaped transition surface at the connection between the shielding part and the mating part, the connection between the shielding part and the mating part can be made smooth, reducing cleaning dead angles, facilitating thorough cleaning of the blade holder, and preventing debris accumulation. Furthermore, if residual water splashes, the transition surface guides the residual water to the flow wall, preventing it from splashing onto the user's arm.

[0012] In a preferred embodiment, the stirring blade is at least partially located radially inside the guide wall.

[0013] By positioning the stirring blades at least partially within the radially inner side of the guide wall, the guide wall not only guides residual water but also directs material flow during blade assembly operation. This causes the material to converge downwards and towards the center, ensuring sufficient contact between the material and the stirring blades, thereby improving pulverization efficiency and fineness.

[0014] In a preferred embodiment, the shielding portion has a lower surface that extends downward and tilts outward.

[0015] By providing an outwardly inclined and downwardly extending lower surface in the shielding section, residual water splashing upwards along the venting channel will be blocked by the upwardly inclined and upwardly extending lower surface. Then, by utilizing the drainage effect of the lower surface, the residual water can flow back to the bottom wall of the mixing cup, preventing splashing.

[0016] In a preferred embodiment, the tool holder is a housing for accommodating the transmission disk. The housing has a top wall, a bottom wall opposite to the top wall, and a side wall connecting the top wall and the bottom wall. The edge of the top wall protrudes from the side wall to form the shielding portion, and the side wall forms the mating portion.

[0017] By setting the tool holder as a housing to accommodate the transmission disk, the top wall, bottom wall and side wall of the housing provide all-round protection for the transmission disk, improving the transmission reliability of the transmission disk and extending its service life. The edge of the top wall protrudes from the side wall to form the shielding part, and the side wall forms the mating part. The tool holder has a simple structure, is easy to process and assemble, and has low manufacturing cost.

[0018] In a preferred embodiment, the top wall of the shell gradually slopes downward from the center outward.

[0019] By gradually tilting the top wall of the shell downwards from the center outwards, the top wall guides the material outwards during the operation of the blade assembly, allowing the material to fully contact the tip of the mixing blade, thus accelerating the pulverization efficiency and improving the fineness of the pulverization.

[0020] In a preferred embodiment, a reinforcing rib is connected between the top wall and the bottom wall of the shell, and the side wall of the shell surrounds the outer periphery of the reinforcing rib.

[0021] Since the top wall, bottom wall, and side wall of the shell form the mounting cavity for accommodating the transmission disk, the overall structural strength is weak while protecting the transmission disk. The tool holder may be broken by dropping or impact. Therefore, reinforcing ribs are added to improve the structural strength of the tool holder.

[0022] In a preferred embodiment, the outer side of the mating part is recessed and provided with a vertically extending venting groove.

[0023] By providing a vertically extending exhaust groove in the recessed outer side of the mating part, the upper and lower chambers separated by the knife holder can achieve air pressure balance not only through the exhaust channel, but also with the assistance of the exhaust groove. Therefore, the size of the exhaust channel only needs to ensure that the installation of the knife holder is not interfered with by the side wall of the mixing cup, and it does not need to be too large, so that a good exhaust and air pressure balance effect can be achieved.

[0024] In a preferred embodiment, a lower attracting magnet is installed on the outer bottom wall of the mixing cup, and an upper attracting magnet is installed inside the blade holder. After the blade holder is installed in place, the upper attracting magnet and the lower attracting magnet attract each other.

[0025] By setting the upper and lower attracting magnets, the blade assembly can be attracted to the bottom wall of the mixing cup, preventing it from detaching during the pouring process and improving user safety. When installing the blade assembly, the attraction between the upper and lower magnets helps the user install it properly, making installation effortless. When removing the blade assembly, the user only needs to overcome the attraction between the upper and lower magnets, allowing for easy disassembly.

[0026] In a preferred embodiment, the stirring cup includes a cup body with an open lower end and a heating plate enclosed at the lower end of the cup body, and the sink is disposed at the bottom of the heating plate;

[0027] Alternatively, the stirring cup includes a cup body with a bottom wall, the side wall of the cup body having a main section and a constricted section located below the main section with a decreasing inner diameter relative to the main section, the constricted section forming the settling groove with the bottom wall of the cup body.

[0028] By placing the settling tank at the bottom of the heating plate, the overall processing and manufacturing of the mixing cup is simplified, the molding cost of the cup body is low, and production is convenient.

[0029] The mixing cup includes a cup body with a bottom wall. A groove is formed by the contraction section and the bottom wall of the cup body. At the same time, the contraction section also facilitates the demolding of the mixing cup, making it easy to process. Moreover, the mixing cup itself has a bottom wall, which has strong sealing performance and eliminates the trouble of separate assembly. Attached Figure Description

[0041] like Figure 1-4 As shown, in one embodiment of the present invention, a food processing machine is provided, including a main unit 10, a mixing cup 20 mounted on the main unit 10, and a blade assembly 30 detachably mounted in the mixing cup 20. The blade assembly 30 includes a blade holder 31, a transmission disk 32 rotatably mounted in the blade holder 31, a mixing blade 33 located above the blade holder 31, and a transmission shaft 34 passing through the blade holder 31 to connect the transmission disk 32 and the mixing blade 33. The main unit 10 is provided with a motor 11 and a drive disk 12 driven by the motor 11. The drive disk 12 drives the transmission disk 32 to rotate in the air. The bottom of the mixing cup 20 is provided with a downwardly recessed groove 201. The blade holder 31 includes a mating part 311 that is inserted into the groove 201 and radially limited by the groove 201. An exhaust channel 40 is provided between the mating part 311 and the side wall of the groove 201. The blade holder 31 also includes a blocking part 312 that protrudes radially outward relative to the top of the mating part 311 to block the exhaust channel 40.

[0042] This invention provides a food processing machine by setting a trough 201 at the bottom of a mixing cup 20. The blade holder 31 includes a mating part 311 that radially limits the movement of the trough 201, ensuring that the blade holder 31 is reliably positioned within the mixing cup 20 after installation, thus achieving stable operation of the mixing blade 33. The exhaust channel 40 provides clearance between the mating part 311 of the blade holder 31 and the side wall of the trough 201, preventing interference and collisions during blade assembly 30 installation, making installation of the blade assembly 30 easy. By providing a shielding part 312 that protrudes radially outward from the top of the mating part 311, even if residual water exists in the mixing cup 20, when the user places the blade assembly 30, the residual water splashes upward through the exhaust channel 40 and is then blocked by the shielding part 312. Figure 2 , 3As shown by the arrow, compared to the traditional case without a shield, this changes the straight upward splashing path of residual water. The residual water, after being blocked by the shield, is diverted towards the side wall of the mixing cup, with some flowing back and preventing it from splashing further upwards onto the user's arm or outside the mixing cup 20, effectively solving the problem of residual water splashing. Furthermore, without adjusting the size of the exhaust channel 40, the blade holder 31 divides the inner cavity of the mixing cup 20 into a lower chamber located in the settling tank 201 and an upper chamber located above the lower chamber. After the blade assembly 30 is installed, the exhaust channel 40 balances the air pressure in the upper and lower chambers. Therefore, when the user needs to remove the blade assembly 30, the lower chamber will not exert too much suction on the blade holder 31, preventing the blade holder 31 from being difficult to disassemble, thus enabling easy removal of the blade assembly 30. In summary, this application, through the cooperation of the exhaust channel 40 and the shield 312, not only prevents residual water from splashing onto the user's arm and outside the mixing cup 20, but also achieves easy installation and removal of the blade assembly 30.

[0043] In addition, since the bottom of the mixing cup 20 is provided with a downwardly recessed groove 201, the blade holder 31 includes a mating part 311 that is inserted into the groove 201 and radially limited by the groove 201. The mating part 311 and the groove 201 radially limit the blade holder 31. Since the shielding part 312 protrudes radially outward relative to the top of the mating part 311, if the blade tip of the mixing blade 33 has large particles of food that cause the blade holder 31 to tilt, the shielding part 312 can preferentially contact the inner wall of the mixing cup 20. In addition, the mating part 311 cooperates with the side wall of the groove 201 to achieve the effect of straightening the blade holder 31, preventing the blade holder 31 from falling out of the groove 201, and effectively preventing the transmission disk 32 from exceeding the driving range of the drive disk 12. Therefore, the transmission is reliable and the blade assembly 30 operates stably.

[0044] In a preferred embodiment, such as Figure 2 As shown, the top of the side wall of the settling tank 201 is connected to a guide wall 202 that extends outward from bottom to top, and the shielding part 312 overlaps with the guide wall 202 in the transverse direction.

[0045] By connecting a guide wall 202 extending gradually outward from bottom to top to the top of the side wall of the settling tank 201, the shielding part 312 overlaps with the guide wall 202 laterally. If there is residual water in the stirring cup 20, its splash path is as follows: Figure 3 As shown, residual water splashes upward along the exhaust channel 40, and changes its splashing direction after being blocked by the shield 312, splashing towards the guide wall 202. When the residual water splashes onto the guide wall 202, it will flow upward or downward along the guide wall 202 by inertia, and will not splash onto the user's arm, and it is also difficult for it to splash out of the mixing cup 20.

[0046] In a preferred embodiment, such as Figure 3As shown, the shielding part 312 folds outward from the top of the mating part 311, and an arc-shaped transition surface 313 is provided at the connection position between the shielding part 312 and the mating part 311.

[0047] By providing an arc-shaped transition surface 313 at the connection between the shielding part 312 and the mating part 311, the connection between the shielding part 312 and the mating part 311 can be made smooth, reducing cleaning dead angles, facilitating thorough cleaning of the blade holder 31, and preventing debris accumulation. Moreover, if there is residual water splashing, the transition surface 313 can be used to guide the residual water to the guide wall 202, preventing it from splashing onto the user's arm.

[0048] Optionally, the shielding portion 312 folds horizontally outward from the top of the mating portion 311, such as... Figure 3 As shown. Of course, the shielding part 312 can also be tilted outward and folded downward from the top of the mating part 311. It can also be understood that the shielding part 312 has a lower surface that extends outward and downward. By providing a lower surface that extends outward and downward in the shielding part 312, when residual water splashes upward along the exhaust channel 40, it will be blocked by the lower surface that extends upward. Then, by utilizing the drainage effect of the lower surface, the residual water can flow back to the bottom wall of the stirring cup 20, preventing splashing.

[0049] In a preferred embodiment, the stirring blade 33 is at least partially located radially inside the guide wall 202.

[0050] It should be noted that this utility model does not limit the specific structure of the stirring blade. For example, in a preferred embodiment, such as... Figure 4 As shown, the stirring blade 33 includes an upper blade 332 and a lower blade 333 connected to the drive shaft 34. The lower blade 333 is connected to the drive shaft 34 at a position lower than the upper blade 332. The lower blade 333 is located radially inside the guide wall 202.

[0051] More preferably, the maximum rotational outer diameter of the lower blade 333 is greater than the maximum rotational outer diameter of the upper blade 332. The upper surface of the seat 31 extends downward at an angle from the center to the edge, and the upper blade 332 or the lower blade 333 includes a blade 331 that extends downward at an angle.

[0052] By positioning the stirring blade 33 at least partially within the radially inner side of the guide wall 202, the guide wall 202 not only guides residual water but also directs material flow during the operation of the blade assembly 30. This causes the material to converge downwards and towards the center, ensuring full contact between the material and the stirring blade 33, thereby improving pulverization efficiency and fineness.

[0053] It should be noted that the present invention does not limit the specific structure of the tool holder. In a preferred embodiment, the tool holder 31 is a housing that accommodates the transmission disk 32. The housing has a top wall, a bottom wall opposite to the top wall, and a side wall connecting the top wall and the bottom wall. The edge of the top wall protrudes from the side wall to form a shielding part 312, and the side wall forms a mating part 311.

[0054] More preferably, the top wall of the shell is connected to the side wall of the shell as a whole to improve the sealing effect, and the bottom wall of the shell is fixedly sealed to the bottom end of the side wall of the shell to realize the assembly of the transmission disk 32, bearings, etc.

[0055] Of course, in other implementation examples, the bottom wall of the shell can be connected to the side wall of the shell to improve the sealing effect, and the top wall of the shell can be fixedly sealed to the top of the side wall of the shell to facilitate the assembly of the transmission disk 32, bearings, etc.

[0056] By setting the tool holder 31 as a housing for accommodating the transmission disk 32, the top wall, bottom wall and side wall of the housing provide all-round protection for the transmission disk 32, thereby improving the transmission reliability of the transmission disk 32 and extending its service life. The edge of the top wall protrudes from the side wall to form a shielding part 312, and the side wall forms a mating part 311. The tool holder 31 has a simple structure, is easy to process and assemble, and has low manufacturing cost.

[0057] In a preferred embodiment, such as Figure 3 As shown, a reinforcing rib 314 connects the top wall and the bottom wall of the shell, and the side wall of the shell surrounds the outer periphery of the reinforcing rib 314.

[0058] Since the top wall, bottom wall and side wall of the shell form a mounting cavity to accommodate the transmission disk 32, the overall structural strength is weak while protecting the transmission disk 32. The tool holder 31 may be broken by falling or by impact. Therefore, by setting reinforcing ribs, the structural strength of the tool holder 31 is improved.

[0059] In a preferred embodiment, such as Figure 3 As shown, the top wall of the shell gradually slopes downward from the center outward.

[0060] By gradually tilting the top wall of the shell downwards from the center outwards, the top wall guides the material outwards during the operation of the blade assembly 30, allowing the material to fully contact the tip of the mixing blade 33, thereby accelerating the crushing efficiency and improving the fineness of the crushing.

[0061] In a preferred embodiment, such as Figure 4 As shown, the outer side of the mating part 311 is recessed and has a vertically extending exhaust groove 50.

[0062] By recessing a vertically extending exhaust groove 50 on the outer side of the mating part 311, the upper and lower chambers separated by the knife holder 31 can not only achieve air pressure balance through the exhaust channel 40, but also achieve air pressure balance with the assistance of the exhaust groove 50. Therefore, the size of the exhaust channel 40 only needs to ensure that the installation of the knife holder 31 is not interfered with by the side wall of the stirring cup 20, and it does not need to be set too large, so that a good exhaust and air pressure balance effect can be achieved.

[0063] In a preferred embodiment, a lower attracting magnet is installed on the outer bottom wall of the stirring cup 20, and an upper attracting magnet is installed inside the blade holder 31. After the blade holder 31 is installed in place, the upper attracting magnet and the lower attracting magnet attract each other.

[0064] By setting up upper and lower magnetic attraction magnets, the blade assembly 30 can be attracted to the bottom wall of the mixing cup 20. During the pouring process, the blade assembly 30 will not detach from the bottom wall of the mixing cup 20 on its own, improving user safety. When installing the mixing blade assembly 33, the attraction between the upper and lower magnetic attraction magnets helps the user to install the blade assembly 30 in place, making installation effortless. When it is necessary to remove the mixing blade assembly 33, the user only needs to overcome the attraction between the upper and lower magnetic attraction magnets manually, without affecting the flexible disassembly of the mixing blade assembly 33.

[0065] Furthermore, this invention does not limit the method of forming the settling tank. In a preferred embodiment, such as... Figure 1-4 As shown, the stirring cup 20 includes a cup body 21 with an open bottom and a heating plate 22 enclosed at the bottom of the cup body 21, with a sink 201 located at the bottom of the heating plate 22.

[0066] By setting the settling tank 201 at the bottom of the heating plate 22, the overall processing and manufacturing of the mixing cup 20 is simple, the molding cost of the cup body 21 is low, and the production and manufacturing are convenient.

[0067] In another preferred embodiment, the stirring cup 20 includes a cup body with a bottom wall. The side wall of the cup body has a main section and a contracting section located below the main section with a smaller inner diameter relative to the main section. The contracting section and the bottom wall of the cup body form a recess 201. The stirring cup 20 includes a cup body with a bottom wall, and the recess 201 formed by the contracting section and the bottom wall of the cup body facilitates the demolding of the stirring cup 20, making it easy to process. Moreover, the stirring cup 20 itself has a bottom wall, providing strong sealing and eliminating the hassle of separate assembly.
