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 portable food processors typically include a main unit with a built-in motor and a detachable juicing cup mounted on top of the main unit. The juicing cup contains a pulverizing device, and the main unit houses the motor that drives this device. When using the food processor, the user places ingredients into the juicing cup, starts the motor, and the pulverizing device pulverizes the ingredients. To control the motor, a circuit board is usually installed inside the main unit. This circuit board connects to the motor to control its start / stop and operating status. For example, Chinese patent CN202120323920.2 discloses a compact juicer whose main unit includes a top cover and a main unit housing that fits with the top cover. Positioning posts at the bottom of the main unit and the three corners of the circuit board are secured with screws. The circuit board is fixed to the main unit housing and separate from the top cover, thus securing the circuit board. However, this method of fixing the circuit board directly to the main unit housing makes it prone to loosening or displacement when subjected to vibration or external force, and may even cause direct impact damage, affecting the normal control of the motor. Another method of fixing the circuit board is disclosed in Chinese Patent CN202421724648.9, which describes a brushless motor and a portable food processor. This method involves a barrier within the juicer's main unit that separates the battery and the brushless motor drive board. The side plate of the barrier covers the outer periphery of the brushless motor drive board, and a locking component passes through the base, side plate, and main unit cover to achieve a locking and fixing effect. While this fixing method provides some protection for the circuit board, the encapsulation of the circuit board by the barrier results in a larger overall structure, particularly in the radial dimension. As existing food processors become more intelligent and their overall performance improves, the size of the circuit board will continue to increase. Further increasing the circuit board size would significantly increase the overall structure, especially the radial dimension, hindering the miniaturization design of the food processor and thus affecting its portability, severely reducing the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a portable food processing machine to solve the problem of how to avoid the decrease in portability of the food processing machine due to the excessive size of the whole machine caused by the increase of the size of the circuit board, while improving the stability of the circuit board by setting a bracket in the existing food processing machine.

[0004] To achieve the above objectives, this utility model provides a portable food processor, including a main unit with a motor and a detachable juicing cup located above the main unit. The main unit includes a top cover, a base fixedly connected below the top cover, and a housing connected between the top cover and the base. The motor is fixed to the top cover. Below the motor, there is a circuit board electrically connected to the motor and a fixed bracket supported below the circuit board. The circuit board and the fixed bracket are clamped and fixed between the top cover and the base, and the outer edge of the circuit board is adjacent to the inner sidewall of the housing. A receiving cavity is formed between the fixed bracket and the base, and a battery for power supply is provided in the receiving cavity.

[0005] This application clamps and fixes the circuit board and the mounting bracket between the top cover and the base. This not only secures the circuit board in place with the bracket but also enhances its stability through the clamping mechanism between the top cover and the base. This prevents the circuit board from loosening due to vibration or impact during use in the portable food processor, thus ensuring a smooth electrical connection between the motor and the circuit board and improving operational stability. Furthermore, the connection and fixation of the top cover and base simultaneously fix and position the circuit board and the mounting bracket, eliminating the need for additional fixing structures, simplifying the assembly process, and improving production efficiency. In addition, compared to a directly exposed circuit board, the mounting bracket provides support and protection, effectively preventing damage from external impacts or bending. Furthermore, the circuit board's outer edge is positioned adjacent to the inner wall of the casing, allowing for a larger radial dimension. This provides space for integrating more functional components, which helps to further improve the overall performance and intelligence level of the portable food processor. At the same time, while increasing the radial dimension of the circuit board, it avoids increasing the radial dimension of the entire machine. This not only improves the compactness of the internal structure of the main unit but also makes the radial dimension of the main unit smaller, making it easier for users to hold and further enhancing the portability of the entire machine.

[0006] Furthermore, a cavity is formed between the fixed bracket and the base, and a battery for power supply is installed inside the cavity. This allows the fixed bracket to support and fix the circuit board while also forming an installation space for the battery together with the base. It also isolates the circuit board from the battery, preventing the battery's heat from being transferred to the circuit board and affecting the stability of the circuit board due to close proximity. At the same time, it is also conducive to the heat dissipation of the battery, thereby improving the reliability and safety of the overall structure.

[0007] In a preferred embodiment of a portable food processor, the circuit board side end is vertically aligned with the fixed bracket side end.

[0008] By aligning the circuit board side end with the fixed bracket side end vertically, the circuit board can match the radial dimension of the fixed bracket, thereby achieving a tight fit and stable cooperation between the circuit board and the fixed bracket. This further enhances the installation stability of the circuit board in the whole machine, while avoiding the situation where the fixed bracket is too large compared to the circuit board, resulting in structural redundancy and an increase in the radial dimension of the whole machine, thus further ensuring the miniaturization of the whole machine.

[0009] In a preferred embodiment of a portable food processor, the end of the fixed bracket does not protrude from the end of the circuit board, and the end of the battery does not protrude from the end of the fixed bracket.

[0010] By setting the side end of the mounting bracket to not protrude from the side end of the circuit board, and the side end of the battery not protruding from the side end of the mounting bracket, the circuit board acts as the outer edge limiting surface of the entire structural component, thereby effectively utilizing the internal space layout of the host, while ensuring that the mounting bracket blocks the heat of the battery, and ensuring that the circuit board is not affected by the heat generated by the battery.

[0011] In a preferred embodiment of a portable food processor, the bottom wall of the top cover is provided with a first mounting post extending downward, and the top wall of the base is provided with a second mounting post extending upward. The first mounting post passes through the circuit board and the fixing bracket and is fixedly connected to the second mounting post.

[0012] By providing a downwardly extending first mounting post on the bottom wall of the top cover and an upwardly extending second mounting post on the top wall of the base, and by having the first mounting post pass through the circuit board and the fixing bracket and then be fixedly connected to the second mounting post, the top cover and the base can be connected and fixed through the cooperation of the first and second mounting posts, while also effectively positioning and supporting the circuit board and the fixing bracket.

[0013] In a preferred embodiment of a portable food processor, the side wall of the first mounting post is provided with an outwardly protruding vertical rib, which abuts against the top surface of the circuit board.

[0014] By providing outwardly protruding vertical ribs on the side wall of the first mounting post, which abut against the top surface of the circuit board, the vertical ribs can limit the axial position of the circuit board, ensuring the stability of the axial position of the circuit board. At the same time, they can also strengthen the structure of the first mounting post, preventing the first mounting post from deforming due to uneven stress during assembly, thereby ensuring the reliability of the assembly and the stability of the overall structure.

[0015] In a preferred embodiment of a portable food processor, the second mounting post is provided with a recessed mounting groove for the bottom end of the first mounting post to be inserted, and the top end of the second mounting post abuts against and is supported on the bottom surface of the fixed bracket.

[0016] By providing a recessed mounting groove for the bottom of the first mounting post to be inserted into, and with the top of the second mounting post abutting and supporting the bottom surface of the fixed bracket, the fixed bracket is effectively supported axially. This ensures the fixed bracket and its circuit board maintain a stable position, preventing displacement or loosening due to vibration or external forces. Simultaneously, the insertion of the first mounting post into the mounting groove allows the second mounting post to radially limit its movement, further enhancing the connection stability between the two posts and ensuring reliable assembly between the top cover and the base.

[0017] In a preferred embodiment of a portable food processor, the top surface of the fixed bracket is further provided with multiple upwardly extending bosses, and the circuit board is provided with positioning ports that mate with the bosses.

[0018] By providing multiple upward-extending bosses on the top surface of the fixed bracket, and positioning ports that mate with the bosses on the circuit board, the circuit board can be precisely positioned in the horizontal direction by inserting the bosses into the positioning ports. This ensures the assembly accuracy and stability between the circuit board and the fixed bracket. At the same time, it can effectively prevent the circuit board from shifting or shaking during the assembly process, thereby improving the overall structural stability and reliability, and also improving the efficiency and convenience of subsequent assembly of the circuit board and the fixed bracket.

[0019] In a preferred embodiment of a portable food processor, the top surface of the fixed bracket is recessed to form a heat dissipation gap between the top surface of the fixed bracket and the circuit board, and the outer periphery of the fixed bracket is also provided with a heat dissipation notch that connects the heat dissipation gap to the outside.

[0020] By recessing the top surface of the mounting bracket, a heat dissipation gap is formed between the top surface of the mounting bracket and the circuit board. The outer periphery of the mounting bracket is also provided with a heat dissipation notch that connects the heat dissipation gap to the outside. This allows the circuit board to effectively dissipate heat through the heat dissipation channel formed by the heat dissipation gap and the heat dissipation notch, thereby improving the heat dissipation efficiency of the circuit board during operation and preventing the normal operation of the circuit board or shortening its service life due to excessive temperature.

[0021] In a preferred embodiment of a portable food processor, the mounting bracket is provided with a downwardly extending limiting plate surrounding the outside of the battery.

[0022] By providing a downward-extending limiting plate to the fixed bracket, which surrounds the outside of the battery, radial positioning of the battery is achieved, preventing the battery from shaking or shifting during use, ensuring the stability and safety of the battery after assembly, and thus protecting the battery.

[0023] In a preferred embodiment of a portable food processor, the top wall of the cover is provided with a ring rib extending downward to the outside of the motor.

[0024] By providing a ring rib extending downward to the outside of the motor on the top wall of the cover, the outside of the motor is enclosed, so that the noise generated by the motor during operation can be effectively blocked and absorbed within the ring rib, thereby reducing the noise transmission of the overall structure and improving the quiet performance and user experience of the food processing machine during operation.

Detailed Implementation

[0027] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0028] 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.

[0029] like Figures 1 to 6As shown, this utility model provides a portable food processor, including a main unit with a motor 7 inside and a detachable juicing cup located above the main unit. The main unit includes an upper cover 1, a base 3 fixedly connected below the upper cover 1, and a housing 2 connected between the upper cover 1 and the base 3. The motor 7 is fixed to the upper cover 1. Below the motor 7, there is a circuit board 4 electrically connected to the motor 7 and a fixed bracket 5 supported below the circuit board 4. The circuit board 4 and the fixed bracket 5 are clamped and fixed between the upper cover 1 and the base 3, and the outer edge of the circuit board 4 is adjacent to the inner side wall of the housing 2. It should be noted that the proximity of the outer edge of the circuit board 4 to the inner side wall of the housing 2 specifically means that the distance between the outer edge of the circuit board and the inner side wall of the housing 2 is between 2mm and 20mm. A receiving cavity is formed between the fixed bracket 5 and the base 3, and a battery 6 for power supply is provided in the receiving cavity.

[0030] This application clamps and fixes the circuit board 4 and the fixing bracket 5 between the upper cover 1 and the base 3. This not only secures the circuit board 4 in place via the fixing bracket 5, but also further enhances its stability through the clamping of the upper cover 1 and the base 3. This prevents the circuit board 4 from loosening due to vibration or impact during use of the portable food processor, thus ensuring a smooth electrical connection between the motor 7 and the circuit board 4 and improving the stability of the circuit board 4's operation. Furthermore, the connection and fixation of the upper cover 1 and the base 3 simultaneously fix and position the circuit board 4 and the fixing bracket 5, eliminating the need for additional fixing structures, simplifying the assembly process, and improving production efficiency. In addition, compared to a directly exposed circuit board 4, the fixing bracket 5 provides support and protection, effectively preventing damage from external impacts or bending. Furthermore, the outer edge of the circuit board 4 is positioned adjacent to the inner wall of the outer casing 2, allowing the radial dimension of the circuit board 4 to be larger. This provides space for integrating more functional components onto the circuit board 4, which helps to further improve the overall performance and intelligence level of the portable food processor. At the same time, while increasing the radial dimension of the circuit board 4, it also avoids increasing the radial dimension of the entire machine. This not only improves the compactness of the internal structure of the main unit but also makes the radial dimension of the main unit smaller, making it easier for users to hold and further enhancing the portability of the entire machine.

[0031] Furthermore, a cavity is formed between the fixed bracket 5 and the base 3, and a battery 6 for power supply is installed in the cavity. This allows the fixed bracket 5 to support and fix the circuit board 4 while also forming an installation space for the battery 6 together with the base 3. It also isolates the circuit board 4 from the battery 6, preventing the battery 6 from being too close to the circuit board 4 and thus avoiding the transfer of heat from the battery 6 to the circuit board 4, which would affect the stability of the circuit board 4. At the same time, it is also conducive to the heat dissipation of the battery 6, thereby improving the reliability and safety of the overall structure.

[0032] It should be noted that this application does not specifically limit the relative relationship between the circuit board 4 and the fixing bracket 5, which can be any of the following embodiments: Example 1: As Figure 1 As shown, in this embodiment, the end of the circuit board 4 is vertically aligned with the end of the fixed bracket 5.

[0033] By aligning the side end of the circuit board 4 vertically with the side end of the fixed bracket 5, the radial dimension of the circuit board 4 can be matched with that of the fixed bracket 5, thereby achieving a tight fit and stable cooperation between the circuit board 4 and the fixed bracket 5. This further enhances the installation stability of the circuit board 4 in the whole machine, while avoiding the situation where the fixed bracket 5 is too large compared to the circuit board 4, resulting in structural redundancy and an increase in the radial dimension of the whole machine, thus further ensuring the miniaturization of the whole machine.

[0034] Example 2: In this example, the end of the fixed bracket 5 does not protrude from the end of the circuit board 4, and the end of the battery 6 does not protrude from the end of the fixed bracket 5.

[0035] By setting the side end of the fixing bracket 5 to not protrude from the side end of the circuit board 4, and the side end of the battery 6 not protruding from the side end of the fixing bracket 5, the circuit board 4 acts as the outer edge limiting surface of the entire structural component, thereby effectively utilizing the internal space layout of the host, while ensuring that the fixing bracket 5 blocks the heat of the battery 6, and ensuring that the circuit board 4 is not affected by the heat generated by the battery 6.

[0036] As a preferred embodiment of this application, such as Figure 1 , Figure 2 As shown, the bottom wall of the upper cover 1 is provided with a first mounting post 11 extending downward, and the top wall of the base 3 is provided with a second mounting post 31 extending upward. The first mounting post 11 passes through the circuit board 4 and the fixing bracket 5 and is fixedly connected to the second mounting post 31. The first mounting post 11 and the second mounting post 31 are provided with positioning structures for clamping the circuit board 4 and the fixing bracket 5.

[0037] By providing a downwardly extending first mounting post 11 on the bottom wall of the upper cover 1 and an upwardly extending second mounting post 31 on the top wall of the base 3, and by having the first mounting post 11 pass through the circuit board 4 and the fixing bracket 5 and then be fixedly connected to the second mounting post 31, the upper cover 1 and the base 3 can be connected and fixed through the cooperation of the first mounting post 11 and the second mounting post 31, while also effectively positioning and supporting the circuit board 4 and the fixing bracket 5. Furthermore, the first mounting post 11 and the second mounting post 31 are provided with a positioning structure for clamping the circuit board 4 and the fixing bracket 5, ensuring that the circuit board 4 and the fixing bracket 5 can be more stably assembled through the positioning structure. At the same time, by using the radial limiting of the first mounting post 11 and the second mounting post 31, the circuit board 4 can be fixed in all directions, which helps to further improve the positional stability of the circuit board 4.

[0038] It should be noted that this application does not specifically limit the positioning structure; as one preferred option in this application, such as... Figure 2 As shown, the positioning structure includes a vertical rib 111 protruding outward from the side wall of the first mounting post 11, and the vertical rib 111 abuts against the top surface of the circuit board 4.

[0039] By setting the positioning structure to include a vertical rib 111 protruding outward from the side wall of the first mounting post 11, the vertical rib 111 abuts against the top surface of the circuit board 4, so that the vertical rib 111 can limit the circuit board 4 in the axial direction, ensuring the stability of the axial position of the circuit board 4. At the same time, it can also strengthen the structure of the first mounting post 11, preventing the first mounting post 11 from deforming due to uneven force during assembly, thereby ensuring the reliability of assembly and the stability of the overall structure.

[0040] As a preferred embodiment of this application, such as Figure 2 As shown, the second mounting post 31 is provided with a recessed mounting groove 311 for the bottom end of the first mounting post 11 to be inserted, and the top end of the second mounting post 31 abuts against and is supported on the bottom surface of the fixed bracket 5.

[0041] By providing a recessed mounting groove 311 in the second mounting post 31 for the bottom end of the first mounting post 11 to be inserted, and by having the top end of the second mounting post 31 abut against and support the bottom surface of the fixed bracket 5, the fixed bracket 5 is effectively supported axially, ensuring that the fixed bracket 5 and the circuit board 4 on it can maintain a stable position and avoid displacement or loosening due to vibration or external force. At the same time, after the first mounting post 11 is inserted into the mounting groove 311, the second mounting post 31 can be radially limited to the first mounting post 11, further improving the connection stability between the first mounting post 11 and the second mounting post 31, thereby ensuring the assembly reliability between the upper cover 1 and the base 3.

[0042] As a preferred embodiment of this application, such as Figure 5 , Figure 6 As shown, the top surface of the fixed bracket 5 is also provided with multiple upwardly extending bosses 51, and the circuit board 4 is provided with positioning ports that cooperate with the bosses 51.

[0043] By providing multiple upwardly extending bosses 51 on the top surface of the fixed bracket 5, and positioning ports that mate with the bosses 51, the circuit board 4 can be precisely positioned in the horizontal direction by inserting the bosses 51 into the positioning ports. This ensures the assembly accuracy and stability between the circuit board 4 and the fixed bracket 5. At the same time, when assembling the fixed bracket 5 and the circuit board 4, it can effectively prevent the circuit board 4 from shifting or shaking during the assembly process, thereby improving the stability and reliability of the overall structure, and improving the efficiency and convenience of subsequent assembly of the circuit board 4 and the fixed bracket 5.

[0044] Furthermore, such as Figure 5 As shown, there are three bosses 51, and the lines connecting the bosses 51 form a triangle. This allows the bosses 51 to not only position the circuit board 4, but also to prevent the circuit board 4 from being mistakenly installed through the cooperation between the bosses 51 and the positioning port. This ensures that the circuit board 4 can be installed quickly and correctly during the assembly process, which helps to improve the assembly efficiency of the circuit board 4.

[0045] As a preferred embodiment of this application, such as Figure 5 As shown, the top surface of the fixed bracket 5 is recessed to form a heat dissipation gap between the top surface of the fixed bracket 5 and the circuit board 4, and the outer periphery of the fixed bracket 5 is also provided with a heat dissipation notch 52 that connects the heat dissipation gap with the outside.

[0046] By recessing the top surface of the fixed bracket 5, a heat dissipation gap is formed between the top surface of the fixed bracket 5 and the circuit board 4. The outer periphery of the fixed bracket 5 is also provided with a heat dissipation notch 52 that connects the heat dissipation gap to the outside. This allows the circuit board 4 to effectively dissipate heat through the heat dissipation channel formed by the heat dissipation gap and the heat dissipation notch 52, thereby improving the heat dissipation efficiency of the circuit board 4 during operation and preventing the normal operation of the circuit board 4 or shortening its service life due to excessive temperature.

[0047] As a preferred embodiment of this application, such as Figure 5 As shown, the fixed bracket 5 is provided with a downwardly extending limiting plate 53, which surrounds the outside of the battery 6.

[0048] By providing a downwardly extending limiting plate 53 to the fixed bracket 5, and having the limiting plate 53 surrounding the outside of the battery 6, the battery 6 is radially limited, preventing it from shaking or shifting during use, ensuring the stability and safety of the battery 6 after assembly, and thus protecting the battery 6.

[0049] As a preferred embodiment of this application, such as Figure 3 As shown, the top wall of the upper cover 1 is provided with a ring rib 12 extending downward to the outside of the motor 7.

[0050] By providing a ring rib 12 extending downward to the outside of the motor 7 on the top wall of the upper cover 1, the outside of the motor 7 is enclosed, so that the noise generated by the motor 7 during operation can be effectively blocked and absorbed within the ring rib 12, thereby reducing the noise transmission of the overall structure and improving the quiet performance and user experience of the food processing machine during operation.

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.
