Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a portable food processing machine. Background Technology

[0002] Existing food processors typically consist of a main unit with a motor and a cup body located above the motor, containing a pulverizing blade. When using the food processor, the user places the food inside the cup, and the pulverizing blade rotates at high speed driven by the motor to process the food. With the increasing demand for portability of food processors when traveling, most manufacturers have produced miniaturized, portable models. For example, the applicant's earlier patent application CN214549067U discloses a portable food processor shaped like a cup with a lid. Users can secure the lid to the cup body to seal the pulverizing chamber. The cup body and motor are both fixed within the same housing. However, this type of machine cannot be deeply cleaned, especially because the cup body is quite deep, making it impossible for users to reach the bottom to clean the area below the pulverizing blade. After prolonged use, a significant amount of dirt accumulates, severely impacting the user experience.

[0003] To address these issues, some manufacturers have separated the motor from the cup body. The motor is housed inside the main unit, while the pulverizing blade is located at the top. The cup body is vertically integrated, with its bottom detachably fixed to the top of the main unit. Users can then detach the cup from the main unit after use for thorough cleaning of both. However, this type of cup typically consists of a metal inner cup and an outer shell covering it. Assembling this type of cup requires securing the inner cup to the outer shell using connectors such as screws, usually located inside the inner cup. This assembly process is inconvenient and significantly impacts efficiency. Furthermore, the assembly structure of the inner cup results in an excessively large overall size. Portable food processors, designed for portability, cannot be too bulky, leading to a low effective utilization rate and a limited single-use food preparation capacity. Utility Model Content

[0004] The purpose of this utility model is to provide a portable food processor to solve the problems of existing portable food processors, which, while making the cup body detachably connected to the main unit for easy cleaning, suffer from inconvenient operation and low assembly efficiency when assembling the metal inner cup with the outer shell, and whose installation and fixing structure of the metal inner cup leads to a relatively low overall effective use of the machine.

[0005] To achieve the above objectives, this utility model provides a portable food processing machine, including a main unit with a motor and a detachable cup body located above the main unit. The cup body is vertically continuous and its bottom end is detachably fixed to the top of the main unit. The cup body includes a metal inner cup and an outer shell covering the outside of the metal inner cup. A mounting bracket is installed on the inner wall of the bottom end of the outer shell. The bottom end of the metal inner cup abuts against the bottom of the mounting bracket, and the top end of the metal inner cup overlaps the top end of the outer shell.

[0006] This application design allows the cup body to be detachably connected to the main unit, enabling users to perform deep cleaning of both the cup and the main unit after use. Users can directly clean the grinding device, making cleaning more convenient and faster, thus improving the user experience. The cup body includes a metal inner cup and an outer shell covering the inner cup. The outer shell protects the inner cup while creating a noise-reducing and heat-insulating space between them. This effectively reduces noise generated within the inner cup, minimizing its transmission to the outside. It also provides heat insulation, preventing burns from the hot outer shell and maintaining the temperature inside the inner cup, ensuring a comfortable drinking temperature even after extended use.

[0007] Furthermore, a mounting bracket is fitted into the inner wall of the bottom of the outer shell. The bottom of the inner metal cup abuts against the lower part of the mounting bracket, and the top of the inner metal cup overlaps with the top of the outer shell. During installation, the mounting bracket is first engaged with the bottom of the outer shell, and then the inner metal cup is installed from bottom to top. During installation, the bottom of the inner metal cup abuts against the bottom of the mounting bracket, which provides a downward force to the inner metal cup. The top of the inner metal cup directly overlaps with the top of the outer shell, which provides an upward force to the inner metal cup. This achieves axial fixation between the inner metal cup and the outer shell. The entire installation process requires no tooling or connectors to secure the inner metal cup to the outer shell, simplifying assembly steps and improving efficiency. Furthermore, eliminating other mounting and fixing structures for the inner metal cup allows for a larger volume, significantly increasing the capacity for single-batch slurry preparation and enhancing the user experience. In addition, the top of the inner metal cup overlaps with the top of the outer shell, which not only limits the position of the inner metal cup but also effectively reduces the probability of the slurry coming into contact with the outer shell when it is poured out of the inner metal cup, thus improving food safety.

[0008] In a preferred embodiment of a portable food processor, the mounting bracket includes a fixing part that snaps into the inner wall of the bottom end of the outer casing and a limiting part that extends inward from the fixing part, and the bottom end of the metal inner cup is provided with an abutting part that bulges outward and abuts against the lower part of the limiting part.

[0009] By including a fixing part that snaps into the inner wall of the bottom of the outer shell and a limiting part that extends inward from the fixing part, the bottom of the metal inner cup is provided with a radially outward protruding abutting part that abuts against the lower part of the limiting part, so that the mounting bracket is snapped and fixed to the inner wall of the outer shell through the fixing part, thereby achieving a fixed connection between the mounting bracket and the outer shell. At the same time, the abutting part of the metal inner cup abuts against the limiting part axially, thereby achieving axial limiting of the metal inner cup and improving the stability of limiting the metal inner cup.

[0010] In a preferred embodiment of a portable food processor, the limiting part is an annular rib extending inward from the fixing part, and the abutting part is a lower outward flange that radially flares outward from the bottom end of the metal inner cup, with the lower outward flange abutting below the annular rib.

[0011] By setting the limiting part as an annular rib extending inward from the fixing part, and setting the abutting part as a lower outward flange that radially flares outward from the bottom of the metal inner cup, the mounting bracket can axially limit the metal inner cup after the lower flange abuts against the lower annular rib. It also has a large contact area in the circumferential direction, which can provide a large limiting force. At the same time, the forming of the limiting part and the abutting part is simple and reliable, which helps to further reduce production costs and improve assembly efficiency. In addition, the lower outward flange can strengthen the metal inner cup and improve the overall strength of the metal inner cup.

[0012] In a preferred embodiment of a portable food processor, the limiting part is a first limiting protrusion extending inward from the fixing part, and the abutting part is a limiting ring extending radially inward from the bottom end of the metal inner cup, with the limiting ring abutting below the first limiting protrusion.

[0013] By setting the limiting part as a first limiting protrusion extending inward from the fixing part, and setting the abutting part as a limiting ring extending radially inward from the bottom of the metal inner cup, the mounting bracket can axially limit the metal inner cup after the limiting ring abuts below the first limiting protrusion, ensuring the positional stability of the metal inner cup. In addition, the distance inwardly extending of the first limiting protrusion is relatively short, so that the space for the metal inner cup to avoid the first limiting protrusion is small, effectively avoiding the situation where the bottom of the entire metal inner cup is greatly recessed due to a large space to avoid the first limiting protrusion, resulting in a smaller volume of the metal inner cup.

[0014] In a preferred embodiment of a portable food processor, the fixing part is provided with an axially extending buckle, and the inner wall of the outer shell is provided with a protruding rib that engages with the buckle.

[0015] By providing an axially extending buckle in the fixing part and a protruding rib on the inner wall of the outer shell that engages with the buckle, the mounting bracket can be quickly fixed to the outer shell during assembly by engaging the buckle with the protruding rib. This simplifies the assembly process, improves production efficiency, ensures a firm connection, and enhances the stability of the overall structure.

[0016] In a preferred embodiment of a portable food processor, the inner wall of the mounting bracket is provided with a radially outward recessed groove, and the metal inner cup is provided with a second limiting protrusion that is radially outward and extends into the groove.

[0017] By providing a radially outward recessed groove on the inner wall of the mounting bracket, and a second limiting protrusion that bulges outward and extends into the groove, the metal inner cup achieves a stable connection with the mounting bracket through the tight fit between the second limiting protrusion and the groove. After the second limiting protrusion and the groove cooperate, the groove can not only limit the axial movement of the metal inner cup, but also limit its movement in the circumferential and radial directions, ensuring the stability of the metal inner cup in multiple dimensions and improving the stability of the overall structure.

[0018] In a preferred embodiment of a portable food processor, a metal heating plate is provided at the top of the main unit, and the metal heating plate and the inner metal cup form a grinding chamber; or,

[0019] The top of the metal inner cup is provided with an upper outward flange that extends outward and overlaps the top of the outer shell. The upper outward flange includes a horizontal segment extending outward and a vertical segment extending downward from the horizontal segment and surrounding the outer side of the outer shell.

[0020] By installing a metal heating plate at the top of the main unit, which forms a grinding chamber with the metal inner cup, the entire inner wall of the grinding chamber is made of metal, improving heat conduction efficiency and ensuring that the food is heated evenly. At the same time, users can perform more powerful deep cleaning of the grinding chamber, ensuring its cleanliness and further enhancing the user experience.

[0021] By setting the upper outer flange to include a horizontal segment extending outward and a vertical segment extending downward from the horizontal segment and surrounding the outer shell, the horizontal segment can overlap the top of the outer shell to achieve vertical restraint of the metal inner cup. At the same time, the vertical segment surrounding the outer shell can achieve radial restraint of the metal inner cup and the outer shell, improving the stability of the connection between the two and further reducing the probability of the slurry contacting the outer shell when the slurry is poured outward, thus further improving food safety.

[0022] In a preferred embodiment of a portable food processor, the mounting bracket is further fixed with a locking structure. After the cup body and the main unit are assembled in place, the cup body is locked to prevent rotation with the main unit through the locking structure.

[0023] By incorporating a locking structure into the mounting bracket, the cup body engages with the main unit in a locking mechanism after assembly. This lock automatically locks the cup body in place, preventing it from loosening or detaching during use. This enhances the stability of the connection between the cup body and the main unit, improving reliability when carrying the food processor. It ensures a tight connection between the main unit and the cup during bumpy transport, preventing food from spilling out due to separation caused by significant vibrations, thus improving the user experience. Furthermore, the mounting bracket simultaneously secures the cup body and the locking structure, serving a dual purpose. This eliminates the need for a separate component for the locking mechanism, contributing to a more compact design, reduced production costs, and optimized overall design. This allows the portable food processor to achieve a perfect balance between functionality and portability.

[0024] In a preferred embodiment of a portable food processor, the locking structure includes a limiting post that can reciprocate axially and an operating component connected to the limiting post. The operating component protrudes from the outer casing and can drive the limiting post to move upward to release the lock between the cup body and the main unit.

[0025] By including an axially reciprocating limiting post and an operating component connected to the limiting post in the locking structure, with the operating component protruding from the outer casing, the operating component can drive the limiting post upward to release the lock between the cup body and the main unit. This allows the limiting post to move downward and lock with the main unit after the user installs the cup body onto the main unit, ensuring the cup body is stable. At the same time, when the user needs to separate the cup body from the main unit, they can easily release the lock by operating the operating component to drive the limiting post upward, allowing the cup body to be smoothly separated from the main unit. The operation is simple and improves the user experience.

[0026] In a preferred embodiment of a portable food processor, a mounting bracket and the bottom of the outer casing enclose a receiving cavity, and a locking structure is installed within the receiving cavity.

[0027] By forming a receiving cavity by enclosing the mounting bracket and the bottom of the outer shell, the locking structure is installed in the receiving cavity, thereby achieving fixed installation of the locking structure and concealing the locking structure to ensure the consistency of the cup's appearance.

Detailed Implementation

[0037] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0038] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figures 1 to 6 As shown, this utility model provides a portable food processor, including a main unit 1 with a motor 3 inside and a detachable cup body 2 located above the main unit 1. The cup body 2 is vertically through and its bottom end is detachably fixed to the top of the main unit 1. The cup body 2 includes a metal inner cup 21 and an outer shell 22 covering the outside of the metal inner cup 21. A mounting bracket 4 is installed on the inner wall of the bottom end of the outer shell 22. The bottom end of the metal inner cup 21 abuts against the bottom of the mounting bracket 4, and the top end of the metal inner cup 21 overlaps the top end of the outer shell 22.

[0040] This application allows the cup body 2 to be detachably connected to the main unit 1, enabling users to perform deep cleaning of both the cup body 2 and the main unit 1 after using the food processor. Users can directly clean the grinding device, making cleaning more convenient and faster, thus improving the user experience. The cup body 2 includes a metal inner cup 21 and an outer shell 22 covering the metal inner cup 21. The outer shell 22 protects the metal inner cup 21 and creates a noise-reducing and heat-insulating space between the metal inner cup 21 and the outer shell 22. This effectively reduces noise generated inside the metal inner cup 21, minimizing noise transmission to the outside. It also provides heat insulation, preventing burns from the hot outer shell 22 when held, and maintaining the temperature inside the metal inner cup 21, allowing users to drink at a comfortable temperature even after prolonged use.

[0041] Furthermore, a mounting bracket 4 is fitted onto the inner wall of the bottom end of the outer shell 22. The bottom end of the metal inner cup 21 abuts against the lower part of the mounting bracket 4, and the top end of the metal inner cup 21 overlaps with the top end of the outer shell 22. During installation, the mounting bracket 4 is first engaged with the bottom end of the outer shell 22, and then the metal inner cup 21 is installed from bottom to top. During installation, the bottom end of the metal inner cup 21 abuts against the bottom end of the mounting bracket 4, and the mounting bracket 4 provides a downward force to the metal inner cup 21. The top end of the metal inner cup 21 directly overlaps with the top end of the outer shell 22, and the top end of the outer shell 22 provides an upward force to the metal inner cup 21. This achieves axial fixed installation of the metal inner cup 21 and the outer shell 22. The entire installation process does not require tooling or connectors to fix the metal inner cup 21 and the outer shell 22, which helps to simplify the assembly steps and improve assembly efficiency. Furthermore, eliminating the need for other installation and fixing structures for the inner metal cup 21 allows for a larger volume of the inner metal cup 21, thereby significantly increasing the capacity of the slurry prepared in a single batch and improving the user experience. In addition, the top of the inner metal cup 21 overlaps with the top of the outer shell 22, which not only limits the position of the inner metal cup 21 against the outer shell 22 but also effectively reduces the probability of the slurry contacting the outer shell 22 when poured out of the inner metal cup 21, thus improving food safety.

[0042] Furthermore, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, during the installation process of the metal inner cup 21 from bottom to top, after the bottom end of the metal inner cup 21 abuts against the mounting bracket 4, the top end of the metal inner cup 21 is pressed outward by a special tool to form an upper outward flange 212 and overlap the top end of the outer shell 22, thereby fixing the outer shell 22 and the top end of the metal inner cup 21.

[0043] It should be noted that this application does not specifically limit the limiting structure of the mounting bracket 4 to the metal inner cup 21, and it can be any of the following embodiments:

[0044] Example 1: As Figure 6 As shown, in this embodiment, the mounting bracket 4 includes a fixing part 42 that is snapped into the inner wall of the bottom end of the outer shell 22 and a limiting part that extends inward from the fixing part 42. The bottom end of the metal inner cup 21 is provided with an abutting part that protrudes radially outward and abuts against the lower part of the limiting part.

[0045] By including a fixing part 42 that snaps into the inner wall of the bottom end of the housing 22 and a limiting part that extends inward from the fixing part 42, and an abutting part that bulges outward at the bottom end of the metal inner cup 21 and abuts against the lower part of the limiting part, the mounting bracket 4 is snapped and fixed to the inner wall of the housing 22 through the fixing part 42, thus achieving a fixed connection between the mounting bracket 4 and the housing 22. At the same time, the abutting part of the metal inner cup 21 abuts against the limiting part axially, thereby achieving axial limiting of the metal inner cup 21 and improving the stability of limiting the metal inner cup 21.

[0046] It should be further noted that this application does not specifically limit the structure of the lower limiting part and the abutting part in this embodiment, and they can be any of the following embodiments:

[0047] Implementation method 1: such as Figure 6 As shown, in this embodiment, the limiting part is an annular rib 41 extending inward from the fixing part 42, and the abutting part is a lower outward flange 213 radially outward at the bottom end of the metal inner cup 21, with the lower outward flange 213 abutting below the annular rib 41.

[0048] By setting the limiting part as an annular rib 41 extending inward from the fixing part 42, and the abutting part as a lower outward flange 213 radially outward at the bottom of the metal inner cup 21, the mounting bracket 4 can axially limit the metal inner cup 21 after the lower flange abuts below the annular rib 41. The contact area in the circumferential direction is large, which can provide a large limiting force. At the same time, the forming of the limiting part and the abutting part is simple and reliable, which helps to further reduce production costs and improve assembly efficiency. Meanwhile, the lower outward flange 213 can strengthen the metal inner cup 21 and improve the overall strength of the metal inner cup 21.

[0049] Implementation Method 2: In this implementation method, the limiting part is a first limiting protrusion extending inward from the fixing part 42, and the abutting part is a limiting ring extending radially inward from the bottom end of the metal inner cup 21, with the limiting ring abutting below the first limiting protrusion.

[0050] By setting the limiting part as a first limiting protrusion extending inward from the fixing part 42, and setting the abutting part as a limiting ring extending radially inward from the bottom end of the metal inner cup 21, the mounting bracket 4 achieves axial limiting of the metal inner cup 21 after the limiting ring abuts below the first limiting protrusion, ensuring the positional stability of the metal inner cup 21. In addition, the distance inwardly extending of the first limiting protrusion is relatively short, so that the space for the metal inner cup 21 to avoid the first limiting protrusion is small, effectively avoiding the situation where the bottom end of the entire metal inner cup 21 is greatly recessed due to the large space to avoid the first limiting protrusion, resulting in a smaller volume of the metal inner cup 21.

[0051] As a preferred embodiment, such as Figure 4 As shown, the fixing part 42 is provided with an axially extending buckle 43, and the inner wall of the outer shell 22 is provided with a protruding rib that engages with the buckle 43.

[0052] By providing an axially extending buckle 43 to the fixing part 42 and a protruding rib that engages with the buckle 43 on the inner wall of the outer shell 22, the mounting bracket 4 can be quickly fixed to the outer shell 22 during assembly by engaging the buckle 43 with the protruding rib. This simplifies the assembly process, improves production efficiency, ensures a firm connection, and enhances the stability of the overall structure.

[0053] Example 2: In this example, the inner wall of the mounting bracket 4 is provided with a radially outward recessed groove, and the metal inner cup 21 is provided with a second limiting protrusion that is radially outward and extends into the groove.

[0054] By providing a radially outward recessed groove on the inner wall of the mounting bracket 4, and a second limiting protrusion that radially protrudes and extends into the groove on the metal inner cup 21, the metal inner cup 21 achieves a stable connection with the mounting bracket 4 through the tight fit between the second limiting protrusion and the groove. After the second limiting protrusion and the groove cooperate, the groove can not only limit the axial movement of the metal inner cup 21, but also limit its movement in the circumferential and radial directions, ensuring the stability of the metal inner cup 21 in multiple dimensions and improving the stability of the overall structure.

[0055] As a preferred embodiment of this application, such as Figure 2 As shown, the top of the main unit 1 is provided with a metal heating plate 5, which together with the metal inner cup 21 forms a crushing chamber 211. Specifically, the crushing blade 6 is located at the center of the metal heating plate 5.

[0056] By providing a metal heating plate 5 at the top of the main unit 1, the metal heating plate 5 and the metal inner cup 21 form a grinding chamber 211, making the entire inner wall of the grinding chamber 211 all metal, improving heat conduction efficiency, ensuring that the food is heated evenly, and allowing users to perform more powerful deep cleaning of the grinding chamber 211, ensuring the cleanliness of the grinding chamber 211, and further improving the user experience.

[0057] As a preferred embodiment of this application, such as Figure 5 As shown, the top of the metal inner cup 21 is provided with an upper outward flange that extends outward and overlaps the top of the outer shell 22. The upper outward flange includes a horizontal segment extending outward and a vertical segment extending downward from the horizontal segment and surrounding the outer side of the outer shell 22.

[0058] By setting the upper outer flange to include a horizontal segment extending outward and a vertical segment extending downward from the horizontal segment and surrounding the outer side of the outer shell 22, the horizontal segment can overlap the top of the outer shell 22 to achieve vertical restriction of the metal inner cup 21. At the same time, the vertical segment surrounding the outer side of the outer shell 22 can achieve radial restriction of the metal inner cup 21 and the outer shell 22, improving the stability of the connection between the two, and further reducing the probability of the slurry contacting the outer shell 22 when the slurry is poured outward, thus further improving food safety.

[0059] As a preferred embodiment of this application, such as Figure 4 , Figure 6 As shown, the mounting bracket 4 is also fixed with a locking structure 7. After the cup body 2 and the main unit 1 are assembled in place, the cup body 2 is locked with the main unit 1 through the locking structure 7 to prevent rotation.

[0060] By fixing a locking structure 7 to the mounting bracket 4, after the cup body 2 and the main unit 1 are assembled, the cup body 2 and the main unit 1 are locked together by the locking structure 7 to prevent rotation. This ensures that the locking structure 7 automatically locks the cup body 2 after it is in place, preventing it from loosening or falling off during use. This further improves the stability of the connection between the cup body 2 and the main unit 1, and enhances the reliability when the user is carrying the food processor. It ensures a tight connection between the main unit 1 and the cup body 2 during bumpy rides, preventing the main unit 1 from separating from the cup body 2 and causing the food inside the cup body 2 to spill out, thus further improving the user experience. Furthermore, the mounting bracket 4 not only secures the cup body 2 but also secures the locking structure 7, serving a dual purpose. This eliminates the need for a separate structural component to install the locking structure 7, contributing to improved structural compactness, reduced production costs, and optimized overall design. This allows the portable food processor to achieve a perfect balance between functionality and portability.

[0061] It should be noted that this application does not specifically limit the locking structure 7. As one preferred embodiment of this application, such as Figure 6 As shown, the locking structure 7 includes a limiting post 72 that can reciprocate along the axial direction and an operating member 71 connected to the limiting post 72. The operating member 71 protrudes from the outer shell 22. The operating member 71 can drive the limiting post 72 to move upward to release the lock between the cup body 2 and the main unit 1. Furthermore, the top wall of the main unit 1 is provided with a limiting hole that is axially aligned with the limiting post 72. The limiting post 72 can move downward and be inserted into the limiting hole to achieve the locking between the cup body 2 and the main unit 1.

[0062] By including a limiting post 72 that can reciprocate axially and an operating component 71 connected to the limiting post 72, the locking structure 7 is externally exposed in the housing 22. The operating component 71 can drive the limiting post 72 to move upward to release the lock between the cup body 2 and the main unit 1. After the user installs the cup body 2 onto the main unit 1, the limiting post 72 can move downward and lock with the main unit 1, ensuring the stability of the cup body 2. At the same time, when the user needs to separate the cup body 2 from the main unit 1, the operating component 71 is used to drive the limiting post 72 to move upward, easily releasing the lock and allowing the cup body 2 to be smoothly separated from the main unit 1. The operation is simple and improves the user experience.

[0063] As a preferred embodiment, such as Figure 6 As shown, the mounting bracket 4 and the bottom of the outer shell 22 form a receiving cavity, and the locking structure 7 is installed in the receiving cavity.

[0064] By forming a receiving cavity by the mounting bracket 4 and the bottom of the outer shell 22, the locking structure 7 is installed in the receiving cavity, thereby achieving the fixed installation of the locking structure 7 and at the same time achieving the concealment of the locking structure 7, ensuring the consistency of the appearance of the cup body 2.

It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
