Description

Technical Field

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

[0002] The applicant has previously developed a lithium battery rechargeable grinder, including a main unit with a built-in motor and a circuit board inside. A panel assembly on the top of the main unit includes a display screen and a touch switch; the display screen shows the battery level. In existing grinders, the touch switch and the battery level display screen are misaligned, resulting in a large internal space occupation and poor structural compactness. Furthermore, the applicant has found that other food processors, such as meat grinders, also suffer from a non-compact panel assembly structure that occupies a large space, hindering the miniaturization and portability of these machines.

[0003] Existing technology, such as the patent with publication number CN206312093U, discloses a touch panel assembly and a rice cooker equipped with the touch panel assembly. The assembly includes a panel, a light-emitting block, a lampshade, and a diffuser. The panel has multiple function button areas, each with a corresponding function name silkscreened on it. The light-emitting block is located on the lower side of the panel, and the lampshade is located between the light-emitting block and the panel. The lampshade has light-transmitting holes corresponding to each function button area. The diffuser is used to adjust the light transmittance of the function button areas. A spring is fitted around the outside of the light-emitting block, with its lower end connected to the control circuit board and its upper end passing through the light-transmitting holes and contacting a light-shielding sheet or the lower surface of the panel. While this design features a compact arrangement of the light-emitting block and spring, saving space, it relies on the lampshade and diffuser between the light-emitting block and the panel to achieve the required light transmittance. Otherwise, poor light transmittance will cause light dispersion and unfocused illumination, resulting in unclear silkscreened function text. The added lampshade not only increases cost but also complicates the structure of the panel assembly. Utility Model Content

[0004] This invention provides a compact food processor that solves the problem of divergent and unfocused light from the light-emitting components in the prior art, which requires the use of a lampshade and results in a complex main unit structure, while achieving a compact internal structure.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a compact food processor, including a main unit with a built-in motor, a pulverizing device driven by the motor, and a cup body. The main unit also has a circuit board, on which a digital tube and a touch spring are fixed. The touch spring is sleeved on the outer periphery of the digital tube. The main unit has a mounting hole and a display screen fixed in the mounting hole. The display screen is correspondingly arranged on the outside of the digital tube and the touch spring, and the outer end of the touch spring abuts against the display screen.

[0007] The food processor provided by this utility model utilizes a digital tube, which has the characteristics of emitting light and displaying numbers. Since a touch spring is sleeved around the digital tube, and the display screen is correspondingly positioned outside both the digital tube and the touch spring, with the outer end of the touch spring abutting against the display screen, when the display screen is pressed, the touch spring triggers the circuit board, thereby causing the digital tube to emit light. The display screen clearly displays countdown or forward countdown numbers. Therefore, a lampshade structure can be eliminated, simplifying the internal display structure of the main unit and reducing the overall cost. Furthermore, the digital tube design eliminates the space required for a lampshade, thereby minimizing the radial distance between the circuit board and the display screen, which is beneficial for miniaturizing the main unit. Additionally, since the touch spring is sleeved around the digital tube, compared to a side-by-side arrangement, the space occupied by the main unit is reduced, resulting in a more compact structure and further miniaturizing the main unit, making it easier for users to store and retrieve.

[0008] In a preferred embodiment, the outer end of the touch spring protrudes from the digital tube, and a clearance gap is provided between the outer end of the digital tube and the display screen.

[0009] By having the outer end of the touch spring protrude from the digital tube, and providing a clearance gap between the outer end of the digital tube and the display screen, the clearance gap provides buffer space for the deformation of the display screen when the user presses the display screen for touch control, thereby effectively preventing the display screen from colliding with the outer end of the digital tube, protecting the digital tube from being squeezed and thus preventing damage to the digital tube, and extending the service life of the host.

[0010] In a preferred embodiment, the digital tube includes a tube body and pins. The tube body has a display end facing the display screen and a mounting end facing the circuit board. The pins extend from the mounting end and are electrically connected to the circuit board. A support frame abuts between the circuit board and the mounting end of the tube body.

[0011] The digital tube is electrically connected to the circuit board via pins so that it can light up and display the corresponding number when triggered by a touch spring. Since the pins themselves have low strength and only need to serve an electrical connection function, while the tube itself has a certain weight, a support frame is abutted between the circuit board and the mounting end of the tube. The support frame provides stable support for the tube, making the installation of the tube and the circuit board more stable and preventing the tube from falling off and causing the pins to break, resulting in display abnormalities. This makes the structure more reliable.

[0012] More preferably, the support frame is a hollow column, and the pins pass through the inner cavity of the hollow column and are connected to the circuit board; or, the digital tube includes multiple pins, and the support frame is disposed between two adjacent pins.

[0013] By setting the support frame as a hollow column, the pins and the hollow column share the space between the tube body and the circuit board, further achieving a compact structure. By placing the support frame between two adjacent pins, the space between the two adjacent pins is rationally utilized, achieving a compact structure, thereby greatly saving host space and facilitating host miniaturization.

[0014] In a preferred embodiment, the circuit board is arranged vertically inside the host and located to the side of the motor.

[0015] By vertically arranging the circuit board inside the host and located to the side of the motor, it is beneficial to make reasonable use of the space between the host and the motor. The structure is compact, and the circuit board and the motor overlap in height, reducing the height of the host, making the center of gravity of the host stable and improving the working stability.

[0016] More preferably, the motor includes a main body and a limiting boss protruding from the outer periphery of the main body. The limiting boss is fixedly connected to the main unit, and the circuit board is located on the side of the main body and overlaps with the limiting boss along the motor axis.

[0017] By setting a limiting boss, which is fixedly connected to the main unit, a reliable connection between the motor and the main unit is achieved. The limiting boss not only acts as a connecting bridge between the motor and the main unit, but also provides radial alignment and limiting for the motor through its protruding structural characteristics. This effectively prevents the motor from shaking or shifting during operation or transportation, thus ensuring stable motor operation and protecting the main unit from damage caused by the motor bumping into it during transport. The circuit board is located on the side of the main body and overlaps with the limiting boss along the motor axis, significantly reducing the radial distance between the motor and the circuit board, thus reducing the radial size of the main unit, achieving miniaturization, making it easier for users to hold, and improving the user experience.

[0018] More preferably, the host is internally fixed with a mounting bracket, on which a first stud and a second stud at a first height are fixed, and on which a third stud at a second height is also fixed, and the circuit board is provided with three screw holes corresponding to the first stud, the second stud and the third stud respectively.

[0019] The circuit board is fixed by setting studs of first and second heights on the mounting bracket, so that the circuit board is stably installed in the host. Moreover, since the number of studs of the first and second heights is different, it has a foolproof effect, preventing the detection board from being installed upside down, so that the digital tube, touch spring and display screen are accurately aligned and installed.

[0020] In a preferred embodiment, the host includes a mounting portion and a stepped portion that expands radially relative to the mounting portion, the motor is mounted in the mounting portion, the circuit board is arranged laterally in the stepped portion, and the display screen is disposed on the stepped surface of the stepped portion.

[0021] By installing the motor in the mounting part and arranging the circuit board laterally in the stepped part, the outer diameter of the main unit mounting part is small for easy gripping. Only the outer diameter of the stepped part is enlarged, which not only makes it easy to install the stepped part above the cup body and match the cup mouth to realize functions such as mincing meat and kneading dough, but also makes reasonable use of the radial space to arrange the circuit board laterally, realizing efficient use of the main unit space.

[0022] In a preferred embodiment, the display screen is disposed on the top wall of the host, and the circuit board is arranged horizontally above the motor.

[0023] By mounting the display screen on the top wall of the main unit, users can easily see the content displayed on the digital tube and operate it more directly. The circuit board is arranged horizontally above the motor, and the circuit board and the motor share the radial space of the main unit, reducing the outer diameter of the main unit and making it easier for users to hold.

[0024] In a preferred embodiment, the display screen includes a display panel and a perimeter protruding from the edge of the display panel. The perimeter is inserted into the mounting hole and sleeved around the outer periphery of the touch spring, and the touch spring abuts against the display panel.

[0025] By setting the display screen as a display panel and a surrounding edge, the surrounding edge is inserted into the mounting hole and sleeved on the outer periphery of the touch spring, thus both limiting the position of the display screen and the mounting hole and limiting the position of the touch spring are achieved by the surrounding edge, so as to avoid the position of the touch spring being offset, which is conducive to sensitive operation. The touch spring abuts against the display panel, and the user presses the display panel to achieve control.

[0026] In a preferred embodiment, the display screen, the digital tube, and the touch spring are arranged coaxially.

[0027] By arranging the display screen, the digital tube, and the touch spring coaxially, the problem of touch insensitivity caused by screen shaking or touch spring shaking due to external force or vibration is reduced, thereby improving the accuracy and convenience of operation. In addition, the structure of the display screen, digital tube, and touch spring is compact.

[0028] In a preferred embodiment, the food processor further includes a connecting housing, which is connected between the output end of the main unit and the open end of the cup body, and a storage chamber is provided on the side of the connecting housing facing the main unit. The grinding device includes a moving grinding head and a stationary grinding head disposed in the connecting housing, and the moving grinding head is drivenly connected to the motor.

[0029] By setting up a connecting housing and providing a storage chamber on the side of the connecting housing facing the main unit, users can put dry-grinding materials, such as coffee beans and nuts, into the storage chamber. By connecting the connecting housing between the output end of the main unit and the open end of the cup, pressing the display screen triggers the touch spring, the digital tube lights up and the motor starts to drive the moving grinding head to rotate. The moving grinding head cooperates with the stationary grinding head to achieve the dry grinding function.

[0030] In a preferred embodiment, the main unit is installed above the cup body, and the pulverizing device is a pulverizing blade installed inside the cup body. The lower end of the pulverizing blade is limited and engaged with the inner bottom wall of the cup body, and the upper end of the pulverizing blade extends out of the cup body and is connected to the motor for transmission.

[0031] By setting the pulverizing device as a pulverizing blade installed inside the cup, with the lower end of the pulverizing blade engaging with the inner bottom wall of the cup and the upper end of the pulverizing blade extending out of the cup and connected to the motor, the user installs the main unit above the cup and, by pressing the display screen, triggers the touch spring, illuminating the digital tube and starting the motor, causing the pulverizing blade to rotate and pulverize the materials inside the cup, thus achieving functions such as mincing meat, chopping vegetables, or kneading dough.

[0048] like Figure 1 , Figure 2 As shown, in one embodiment of the present invention, a compact food processor is provided, including a main unit 10 with a built-in motor 11, a pulverizing device 20 driven by the motor 11, and a cup body 30. The main unit 10 also has a circuit board 12, on which a digital tube 13 and a touch spring 14 are fixed. The touch spring 14 is sleeved on the outer periphery of the digital tube 13. The main unit 10 has a mounting hole and a display screen 15 fixed in the mounting hole. The display screen 15 is correspondingly arranged on the outside of the digital tube 13 and the touch spring 14, and the outer end of the touch spring 14 abuts against the display screen 15.

[0049] The food processor provided by this utility model employs a digital tube 13, which has the characteristics of emitting light and displaying numbers. Since a touch spring 14 is sleeved on the outer periphery of the digital tube 13, and a display screen 15 is correspondingly positioned outside the digital tube 13 and the touch spring 14, with the outer end of the touch spring 14 abutting against the display screen 15, when the display screen 15 is pressed, the touch spring 14 triggers the circuit board 12, thereby causing the digital tube 13 to emit light. The display screen 15 clearly displays countdown or forward countdown numbers. Therefore, the lampshade structure can be eliminated, simplifying the display structure inside the main unit 10 and reducing the overall cost. Moreover, the arrangement of the digital tube 13 eliminates the space required for a lampshade, thereby minimizing the radial distance between the circuit board 12 and the display screen 15, which is beneficial for the miniaturization design of the main unit 10. Simultaneously, since the touch spring 14 is sleeved on the outer periphery of the digital tube 13, compared to a side-by-side arrangement, the space occupied by the main unit 10 can be reduced, resulting in a compact structure and further miniaturization of the main unit 10.

[0050] like Figure 2 As shown, more preferably, the display screen 15, the digital tube 13 and the touch spring 14 are arranged coaxially.

[0051] By arranging the display screen 15, digital tube 13 and touch spring 14 coaxially, the problem of screen shaking and touch insensitivity caused by the shaking of the touch spring 14 due to external force or vibration is reduced, thereby improving the accuracy and convenience of operation. In addition, the display screen 15, digital tube 13 and touch spring 14 are arranged in a compact structure.

[0052] Of course, in other embodiments of this utility model, preferably, the display screen 15 and the touch spring 14 are arranged coaxially, and the digital tube 13 is offset to one side relative to the touch spring.

[0053] like Figure 2 As shown, in a preferred embodiment of the present invention, the outer end of the touch spring 14 protrudes from the digital tube 13, and a clearance S is provided between the outer end of the digital tube 13 and the display screen 15.

[0054] By having the outer end of the touch spring 14 protrude from the digital tube 13, and a clearance gap is provided between the outer end of the digital tube 13 and the display screen 15, the clearance gap provides a buffer space for the deformation of the display screen 15 when the user presses the display screen 15 for touch control, thereby effectively preventing the display screen 15 from colliding with the outer end of the digital tube 13, protecting the digital tube 13 from being squeezed and thus preventing damage to the digital tube 13, and extending the service life of the host 10.

[0055] It should be noted that this utility model does not limit the specific form of the food processor, for example:

[0056] Implementation Example 1, such as Figure 1-6 As shown, the food processor is a dry grinder, which can be used to grind coffee beans, nuts, etc.

[0057] Specifically, such as Figure 3 As shown, the food processor also includes a connecting housing 40, which is connected between the output end of the main unit 10 and the open end of the cup body 30, in combination. Figure 1 A storage chamber 106 is provided on the side of the connecting housing 40 facing the host 10. The crushing device 20 includes a moving grinding head 21 and a stationary grinding head 22 disposed in the connecting housing 40. The moving grinding head 21 is connected to the motor 11 for transmission.

[0058] By setting up a connecting housing 40, and providing a storage chamber on the side of the connecting housing 40 facing the main unit 10, users can put dry-grinding materials, such as coffee beans and nuts, into the storage chamber. By connecting the connecting housing 40 between the output end of the main unit 10 and the open end of the cup body 30, pressing the display screen 15 triggers the touch spring 14, the digital tube 13 lights up and the motor 11 starts to drive the moving grinding head 21 to rotate. The moving grinding head 21 cooperates with the stationary grinding head 22 to achieve the dry grinding function.

[0059] like Figure 1 As shown, in this embodiment, the circuit board 12 is vertically arranged inside the host 10 and located to the side of the motor 11.

[0060] More preferably, such as Figure 1 As shown, the motor 11 includes a main body 111 and a limiting boss 112 protruding from the outer periphery of the main body. The limiting boss 112 is fixedly connected to the main unit 10. The circuit board 12 is located on the side of the main body 111 and overlaps with the limiting boss 112 along the motor axis. Specifically, as shown... Figure 1 As shown, the circuit board 12 is located on the side of the main body, and a wiring terminal 121 is also protruding on the side of the circuit board 12 facing the main body. The wiring terminal 121 overlaps with the limiting boss along the axial direction of the motor 11.

[0061] Of course, in other implementation examples, optionally, the body of the circuit board 12 and the limiting boss 112 overlap along the motor axis; or, the body of the circuit board 12 and the module protruding from the body both overlap with the limiting boss 112.

[0062] Combination Figure 4 A positioning stud 175 is provided on the base 105 of the main unit. The screw passes through the limiting boss 112 and is locked to the positioning stud to fix the motor. More preferably, the base 105 is provided with an anti-rotation stud 176. The screw is inserted into the anti-rotation stud 176 and cooperates with the limiting boss to stop the motor from rotating.

[0063] This embodiment arranges the circuit board 12 vertically inside the host 10 and to the side of the motor 11, which helps to make reasonable use of the space between the host 10 and the motor 11. The structure is compact, and the circuit board 12 and the motor 11 overlap in height, reducing the height of the host 10, making the center of gravity of the host 10 stable and improving the working stability.

[0064] By setting a limiting boss 112 and fixing it to the main unit 10, a reliable connection between the motor 11 and the main unit 10 is achieved. The limiting boss not only acts as a connecting bridge between the motor 11 and the main unit 10, but also provides radial alignment and limiting for the motor 11 through its protruding structural characteristics. This effectively prevents the motor 11 from shaking or shifting during operation or transportation, thus ensuring the stable operation of the motor 11 and preventing the motor 11 from bumping into the main unit 10 and breaking it during transportation, thus protecting the main unit 10. The circuit board 12 also has a protruding terminal block on the side facing the main body, which facilitates the wiring harness insertion between the circuit board 12 and other structures, making assembly convenient. The terminal block overlaps with the limiting boss along the axial direction of the motor 11, thereby greatly reducing the radial distance between the motor 11 and the circuit board 12, reducing the radial size of the main unit 10, miniaturizing the main unit 10, making it easier for users to hold, and improving the user experience.

[0065] More preferably, such as Figure 4 , 5 As shown in this embodiment, the host 10 is internally fixed with a mounting bracket 17. The mounting bracket 17 is fixed with a first stud 171 and a second stud 172 at a first height. The mounting bracket 17 is also fixed with a third stud 173 at a second height. The circuit board 12 is provided with three screw holes 174 corresponding to the first stud 171, the second stud 172 and the third stud 173 respectively.

[0066] Specifically, the main unit 10 includes a cylinder 103 that surrounds the motor 11, a cover 104 fixed to the top of the cylinder 103, and a base 105 fixed to the bottom of the cylinder 103. The mounting bracket 17 includes a boss protruding from the base 105 of the main unit 10 and a bracket protruding from one side of the boss and extending upward. The first stud 171 and the second stud 172 are located on the side wall of the boss, and the third stud 173 is located on the bracket.

[0067] The circuit board 12 is fixed by setting studs of first and second heights on the mounting bracket 17, so that the circuit board 12 is stably installed in the host 10. Moreover, since the number of studs of the first and second heights is different, it has a foolproof effect, preventing the detection board from being installed upside down, so that the digital tube 13, touch spring 14 and display screen 15 are accurately aligned and installed.

[0068] Of course, it should be noted that in a modified embodiment of this example, the circuit board 12 can be arranged horizontally in the host 10. For example, the circuit board 12 can be placed horizontally above the motor 11, and the display screen 15 can be located on the top wall of the host 10. It is understood that the above arrangement of the circuit board 12 can also be applied to other embodiments of this utility model.

[0069] Furthermore, the method of fixing the circuit board 12 is not limited to the one described above. For example, in other embodiments, a slot can be provided on the inner wall of the host 10 housing, and the circuit board 12 can be inserted into the slot. The method of fixing the circuit board 12 is also applicable to other embodiments of this invention.

[0070] This utility model does not limit the structure of the display screen 15. Preferably, in this embodiment, such as... Figure 2 , 6 As shown, the display screen 15 includes a display panel 151 and a perimeter 152 protruding from the edge of the display panel 151. The perimeter 152 is inserted into the mounting hole and sleeved on the outer periphery of the touch spring 14. The touch spring 14 abuts against the display panel 151.

[0071] More preferably, such as Figure 6 As shown, a hook 153 is provided at the end of the edging 152 to engage with the main unit.

[0072] By setting the display screen 15 as a display panel 151 and a surrounding edge 152, the surrounding edge 152 is inserted into the mounting hole and sleeved on the outer periphery of the touch spring 14, thus both limiting the display screen 15 and the mounting hole are achieved, and the surrounding edge 152 is used to limit the touch spring 14 to prevent the touch spring 14 from shifting position, which is conducive to sensitive operation. The touch spring 14 abuts against the display panel 151, and the user presses the display panel 151 to achieve control.

[0073] In a preferred embodiment of this invention, such as this example, Figure 4 As shown, the digital tube 13 includes a tube body 131 and pins 132. The tube body 131 has a display end facing the display screen 15 and a mounting end facing the circuit board 12. The pins 132 extend from the mounting end and are electrically connected to the circuit board 12. A support frame 16 abuts between the circuit board 12 and the mounting end of the tube body 131.

[0074] The digital tube 13 is electrically connected to the circuit board 12 via pin 132 so that it can light up and display the corresponding number when triggered by the touch spring 14. Since the pin 132 itself has low strength, it only needs to serve the function of electrical connection. However, the tube body 131 itself has a certain weight. Therefore, a support frame 16 is abutted between the circuit board 12 and the mounting end of the tube body 131. The support frame 16 provides stable support for the tube body 131, making the installation of the tube body 131 and the circuit board 12 more stable. This prevents the tube body 131 from falling off and causing the pin 132 to break, resulting in display abnormalities and making the structure more reliable.

[0075] Of course, this utility model does not limit the structure of the support frame 16. For example, the support frame 16 is a hollow column, and the pin 132 passes through the inner cavity of the hollow column and connects to the circuit board 12.

[0076] Alternatively, the digital tube 13 may include multiple pins 132, with the support frame 16 positioned between two adjacent pins 132.

[0077] Alternatively, the support frame 16 can be a hollow support frame with multiple support ribs.

[0078] By setting the support frame 16 as a hollow column, the pins 132 and the hollow column share the space between the tube body 131 and the circuit board 12, further achieving a compact structure; by setting the support frame 16 between two adjacent pins 132, the space between the two adjacent pins 132 is rationally utilized, achieving a compact structure, thereby greatly saving space in the host 10 and facilitating the miniaturization of the host 10.

[0079] Implementation Example 2, such as Figure 7 , 8 As shown, the food processor is a meat grinder, which can grind meat, chop vegetables, or knead dough.

[0080] Specifically, the main unit 10 is installed above the cup body 30, and the crushing device 20 is a crushing blade 23 installed inside the cup body 30. The lower end of the crushing blade 23 is limited and matched with the inner bottom wall of the cup body 30, and the upper end of the crushing blade 23 extends out of the cup body 30 and is connected to the motor 11 for transmission.

[0081] By setting the pulverizing device 20 as a pulverizing blade 23 installed inside the cup body 30, with the lower end of the pulverizing blade 23 being limited and engaged with the inner bottom wall of the cup body 30, and the upper end of the pulverizing blade 23 extending out of the cup body 30 and being connected to the motor 11 for transmission, the user installs the main unit 10 above the cup body 30, presses the display screen 15, triggers the touch spring 14, lights up the digital tube 13 and starts the motor 11, causing the pulverizing blade 23 to rotate and pulverize the materials inside the cup body 30, thus realizing functions such as mincing meat, chopping vegetables or kneading dough.

[0082] like Figure 7 , 8As shown, in this embodiment, the host 10 includes a mounting portion 101 and a stepped portion 102 that expands radially relative to the mounting portion 101. The motor 11 is mounted in the mounting portion 101, the circuit board 12 is arranged laterally in the stepped portion 102, and the display screen 15 is disposed on the stepped surface of the stepped portion 102.

[0083] By installing the motor 11 inside the mounting part 101 and arranging the circuit board 12 laterally inside the step part 102, the outer diameter of the mounting part 101 of the main unit 10 is small and easy to hold. Only the outer diameter of the step part 102 is enlarged, which not only makes it easy to install the step part 102 above the cup body 30 and match the cup mouth of the cup body 30 to realize functions such as mincing meat and kneading dough, but also makes reasonable use of the radial space to arrange the circuit board 12 laterally, realizing efficient use of the space of the main unit 10.

[0084] In Implementation Example 3, the food processor is still a meat grinder, but it differs from Implementation Example 2 in the form of the main unit 10 and the arrangement of the circuit board 12.

[0085] like Figure 9 As shown, specifically, the display screen 15 is mounted on the top wall of the host 10, and the circuit board 12 is arranged horizontally above the motor 11.

[0086] By mounting the display screen 15 on the top wall of the host 10, users can easily see the display content of the digital tube 13 and operate it more directly. The circuit board 12 is arranged horizontally above the motor 11. The circuit board 12 and the motor 11 share the radial space of the host 10, reducing the outer diameter of the host 10 and making it easier for users to hold.
