Description

Technical Field

[0001] This invention relates to the field of juicing cup technology, specifically a three-section juicing cup. Background Technology

[0002] With the continuous development of technology, there are more and more types of juicer cups. In terms of detachable structure, in addition to the traditional one-piece openable lid structure, that is, the cup base and cup body are one piece, and the cup body and cup lid are detachable; there are also three-section structures, which are the cup base, cup body and cup lid. The cup base and cup body can be easily disassembled, and the cup body and cup lid can also be easily disassembled. The main way to disassemble is through the threads between the two to screw them together and unscrew them.

[0003] Currently, the structure of three-section juicer cups is often similar to that described in Chinese utility model patent CN215127087U, "A Portable Juicer Cup." Besides the cup body, lid, base, motor, blade assembly, circuit board, battery, and push-button switch, it also includes a button signal switch. The button signal switch is located within the base, with its button extending through a button hole. The button engages with the external threaded interface of the cup body. This structure ensures that the push-button switch can only be operated when the external and internal threaded interfaces of the cup body are fully engaged, improving safety. By incorporating a button signal switch, the system can detect whether the cup body is properly installed, thus controlling, for example, whether power is supplied. This prevents children from accidentally pressing the switch out of curiosity and activating the motor to drive the blade assembly, potentially causing injury, if the cup body is not properly secured.

[0004] When using a three-section juicing cup, the above detection design can only detect whether the cup body is installed correctly, but cannot detect whether the lid is installed correctly. During juicing, the motor drives the blades to rotate, which creates a stirring effect on the liquid inside the cup (juice obtained from the blades crushing fruit or added water, etc.). When the motor speed is high and the lid is not installed, the rapid stirring effect can easily cause the liquid inside the cup to splash out without the lid's protection, increasing the difficulty of cleaning. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, this invention aims to provide a three-section juicing cup that can detect whether the cup body and the lid are properly installed, and thus make different controls based on whether the cup body and the lid are properly installed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a three-section juicing cup, comprising a cup base, a cup body, a cup lid, a main controller, a power module, and a control switch.

After the position switch is in position, the main controller outputs control to the motor in the first control mode; After the position switch is in position and the identification signal from the identification unit is received, the main controller outputs control to the motor in the second control mode.

[0007] As a further aspect of the present invention: the first control mode includes motor speed limiting control; the second control mode includes de-limiting motor speed limiting control; wherein, in the first control mode, the maximum motor speed N1max controlled and output by the main controller responding to the control switch is less than the maximum motor speed N2max controlled and output by the main controller responding to the control switch in the second control mode. As a further aspect of the present invention: the first control mode and the second control mode are for adjusting the control of the maximum output voltage or the maximum output current of the motor.

[0008] As a further aspect of the present invention: the cup body includes a bottle body, the top side of which forms an inwardly narrowed upper bottleneck, the upper bottleneck having an external thread for screwing with a cup lid, the bottom side of which forms an inwardly narrowed lower bottleneck, the lower bottleneck having an external thread for screwing with a cup base; the cup lid forms a first outer cover portion corresponding to the upper bottleneck, the first outer cover portion having a corresponding internal thread; the cup base forms a second outer cover portion corresponding to the lower bottleneck, the second outer cover portion having a corresponding internal thread.

[0009] As a further aspect of the present invention: the outer side of the bottle body is recessed to form a first mounting groove and a second mounting groove communicating with the top side and the bottom side of the bottle body. A first insulating strip is installed on the first mounting groove, and a second insulating strip is installed on the second mounting groove. The first terminal wire is fixed to the first insulating strip. The first conductive contact end of the first terminal wire is a first spring pin contact end fixed to the first insulating strip and extending upward beyond the top side of the bottle body. The second conductive contact end of the first terminal wire is a second spring pin contact end fixed to the first insulating strip and extending downward beyond the bottom side of the bottle body. The second terminal wire is fixed to the second insulating strip. The third conductive contact end of the second terminal wire is a third spring pin contact end fixed to the second insulating strip and extending upward beyond the top side of the bottle body. The fourth conductive contact end of the second terminal wire is a fourth spring pin contact end fixed to the second insulating strip and extending downward beyond the bottom side of the bottle body.

[0014] As a further aspect of the present invention: the identification unit includes a resistive element with a specified resistance value connected in series with the first input contact terminal and the first output contact terminal.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The positioning switch allows the cup body to be triggered when it is properly installed on the cup holder, thus identifying whether the cup body is properly installed. This enables the main controller to enter the first control mode in response to the positioning switch's trigger. After both the cup body and lid are properly installed, the identification unit on the lid and its extended first input contact terminal and first output contact terminal, and the main controller on the cup holder and its extended second output contact terminal and second input contact terminal, can form a contact circuit through the first terminal line on the cup body and its extended first conductive contact terminal, second conductive contact terminal, and second terminal line and its extended third conductive contact terminal and fourth conductive contact terminal. This allows the main controller to obtain the identification signal from the identification unit through the connected detection circuit, thereby identifying that both the cup body and lid are properly installed. This enables the main controller to enter the second control mode in response to obtaining the identification signal, resulting in more intelligent overall control.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-10 A three-section juicing cup includes a cup base 1, a cup body 2, a cup lid 3, a main controller 4, a power module 5, and a control switch 6. The lower end of the cup body 2 is screwed to the cup base 1, and the upper end of the cup body 2 is screwed to the cup lid 3. A motor 7 is installed inside the cup base 1. The output shaft of the motor 7 or a power shaft connected to the output shaft of the motor is inserted into the cup body 2 and connected to a blade assembly 701. A position switch 8 corresponding to the lower end of the cup body 2 is installed on the cup base 1. The main controller 4, the power module 5, and the control switch 6 are all installed on the cup base 1.

[0022] This three-section juicer also includes a detection circuit 9 electrically connected to the main controller 4. The detection circuit 9 includes a first terminal line 901, a second terminal line 902, an identification unit 903, a second output contact 904, and a second input contact 905.

[0023] The first terminal wire 901 is disposed on the cup body 2 and extends downward from the upper end of the cup body 2 to the lower end of the cup body 2. The first terminal wire 901 forms a first conductive contact end 9011 located on the outer side of the upper end of the cup body 2, and the first terminal wire 901 forms a second conductive contact end 9012 located on the outer side of the lower end of the cup body 2.

[0024] The second terminal wire 902 is disposed on the cup body 2 and extends downward from the upper end of the cup body 2 to the lower end of the cup body 2. The second terminal wire 902 forms a third conductive contact end 9021 located on the outer side of the upper end of the cup body 2, and a fourth conductive contact end 9022 located on the outer side of the lower end of the cup body 2.

[0025] The identification unit 903 is disposed inside the cup lid 3. The identification unit 903 has a first input contact terminal 9031 that extends out of the cup lid 3 and corresponds to the first conductive contact terminal 9011 or the third conductive contact terminal 9021, and a first output contact terminal 9032 that extends out of the cup lid 3 and corresponds to the third conductive contact terminal 9021 or the first conductive contact terminal 9011. The second output contact 904 is mounted on the cup holder 1 and corresponds to the second conductive contact 9012 or the fourth conductive contact 9022. The second output contact 904 is electrically connected to the detection voltage output Vout of the main controller 4.

[0026] The second input contact 905 is mounted on the cup holder 1 and corresponds to the fourth conductive contact 9022 or the second conductive contact 9012. The second input contact 905 is electrically connected to the detection voltage feedback terminal Vin of the main controller 4.

[0027] After the position switch 8 is triggered, the main controller 4 outputs control to the motor 7 in the first control mode.

[0028] After the position switch 8 is triggered and the identification signal from the identification unit 903 is received, the main controller 4 outputs control to the motor 7 in the second control mode.

[0029] The design incorporates a position switch 8, which is triggered when the cup body 2 is installed on the cup holder 1. This allows the system to identify whether the cup body is properly installed, enabling the main controller 4 to respond to the position trigger of the position switch 8 and enter the first control mode.

[0030] After the cup body 2 and the cup lid 3 are installed in place, the identification unit 903 on the cup lid 3 and its extended first input contact terminal 9031, first output contact terminal 9032 and the main controller 4 on the cup base 1 and its extended second output contact terminal 904, second input contact terminal 905 can form a contact circuit through the first terminal line 901 on the cup body 2 and its extended first conductive contact terminal 9011, second conductive contact terminal 9012 and second terminal line 902 and its extended third conductive contact terminal 9021, fourth conductive contact terminal 9022. That is, the main controller 4 can obtain the identification signal of the identification unit 903 through the connected detection circuit 9, thereby identifying that the cup body 2 and the cup lid 3 are installed in place, so that the main controller 4 can respond to the acquisition of the identification signal and enter the second control mode, making the overall control more intelligent.

[0031] In this embodiment of the invention, the first control mode includes motor speed limiting control; the second control mode includes de-limiting motor speed limiting control; wherein, in the first control mode, the maximum value of the motor speed N1max output by the main controller 4 in response to the control switch 6 is less than the maximum value of the motor speed N2max output by the main controller 4 in response to the control switch 6 in the second control mode.

[0032] Preferably, the first control mode and the second control mode are for adjusting the control of the maximum output voltage or the maximum output current of the motor.

[0033] In the first control mode, when the user inputs a command to adjust the speed of the motor through the control switch 6, the main controller 4 outputs control to the motor 7 in the first control mode, that is, the maximum speed of the output control does not exceed N1max.

[0034] The control switch 6 can, for example, input commands for low-speed juicing, medium-speed juicing, and high-speed juicing. In the first control mode, when the user inputs a low-speed juicing command through the control switch 6, the main controller 4 controls the motor to rotate at a base speed N lower than N1max; when the user inputs a medium-speed juicing command through the control switch 6, the main controller 4 controls the motor to rotate at a speed N1max; when the user inputs a high-speed juicing command through the control switch 6, the main controller 4 does not respond and controls the motor to rotate at a speed N1max or at a base speed N lower than N1max.

[0035] In the second control mode, when the user inputs a command to adjust the speed of the motor 7 through the control switch 6, the main controller 4 outputs control to the motor in the second control mode, that is, the maximum speed of the output control does not exceed N2max.

[0036] The control switch 6 can, for example, input commands for low-speed juicing, medium-speed juicing, and high-speed juicing. In the second control mode, when the user inputs a low-speed juicing command through the control switch 6, the main controller 4 controls the motor to rotate at a base speed N; when the user inputs a medium-speed juicing command through the control switch 6, the main controller 4 controls the motor to rotate at a speed N1max; and when the user inputs a high-speed juicing command through the control switch 6, the main controller 4 controls the motor to rotate at a speed N2max, which is greater than the speed N1max.

[0037] The design detects whether the cup body 2 and the lid 3 are properly installed. When the cup body 2 is installed but the lid 3 is not, the motor 7 is restricted from high-speed rotation to prevent excessive splashing when the rotating blade assembly 701 is chopping and juicing fruits and vegetables, thus avoiding increased cleaning difficulty and excessive waste. When the cup body 2 and the lid 3 are installed, the restriction on high-speed rotation of the motor 7 is lifted. While ensuring that the cleaning difficulty and splashing waste are avoided, the high-speed rotation can drive the blade assembly to quickly chop and juic, thus completing the juicing process more quickly.

[0038] In this embodiment of the invention, the cup body 2 includes a bottle body 201, an inwardly recessed upper bottleneck 202 is formed on the top side of the bottle body 201, the upper bottleneck 202 has an external thread for screwing with the cup lid 3, and an inwardly recessed lower bottleneck 203 is formed on the bottom side of the bottle body 201, the lower bottleneck 203 has an external thread for screwing with the cup base 1.

[0039] The cup lid 3 has a first outer cover portion 101 corresponding to the upper bottleneck 202. The first outer cover portion 101 has a corresponding internal thread, which can be screwed onto the cup body.

[0040] The cup holder 1 has a second outer cover portion 301 corresponding to the lower neck 203. The second outer cover portion 301 has a corresponding internal thread, which can be screwed to the cup body.

[0041] The outer side of the bottle body 201 is recessed to form a first mounting groove 204 and a second mounting groove 205 that connect the top side and the bottom side of the bottle body 201. A first insulating strip 206 is installed on the first mounting groove 204, and a second insulating strip 207 is installed on the second mounting groove 205.

[0042] The first terminal wire 901 is fixed on the first insulating strip 206. The first conductive contact end 9011 of the first terminal wire 901 is a first spring pin contact end fixed on the first insulating strip 206 and extending upward beyond the top side of the bottle body 201. The second conductive contact end 9012 of the first terminal wire 901 is a second spring pin contact end fixed on the first insulating strip 206 and extending downward beyond the bottom side of the bottle body 201.

[0043] The second terminal wire 902 is fixed on the second insulating strip 207. The third conductive contact end 9021 of the second terminal wire 902 is a third spring pin contact end fixed on the second insulating strip 207 and extending upward beyond the top side of the bottle body 201. The fourth conductive contact end 9022 of the second terminal wire 902 is a fourth spring pin contact end fixed on the second insulating strip 207 and extending downward beyond the bottom side of the bottle body 201.

[0044] The use of spring pins ensures that even if the cup lid 3 is not fully tightened, the detection circuit 9 can still form a circuit after the first input contact terminal 9031 and the first output contact terminal 9032 contact with the corresponding spring pin contact terminal. That is, even when the cup lid 3 is on but not fully tightened, the cup lid 3 still has the function of preventing splashing. For users with less strength, they do not need to tighten the cup lid 3 to a fully tightened state; they only need to tighten it to, for example, more than 80%.

[0045] It uses a spring needle as a contact, which can effectively ensure the stability of the contact connection during the juicing process driven by the motor and the blade assembly. The detection circuit is not easily disconnected by vibration and can continuously and stably detect.

[0046] Preferably, the first mounting groove 204 is a vertically guided sliding groove, and the first insulating strip 206 is slidably connected to the first mounting groove 204. The second mounting groove 205 is a vertically guided sliding groove, and the second insulating strip 207 is slidably connected to the second mounting groove 205. On the one hand, the insulating strip can be installed in the corresponding mounting groove by vertical insertion, which is convenient for installation. On the other hand, the positions of the first insulating strip 206 and the second insulating strip 207 can be adjusted vertically, allowing the user to freely balance the excess length of the upper and lower spring pins, thus improving applicability.

[0047] The insulating strips (206, 206) and the corresponding mounting grooves (204, 205) can be interference fit. The corresponding sliding friction is generated by elastically squeezing the insulating strips. This sliding friction allows the insulating strips to slide and shift on the corresponding mounting grooves when the user applies force, and they do not easily slide on their own in a free state.

[0048] Preferably, the first input contact 9031 is a first conductive sheet fixed to the bottom side of the first outer cover portion 101, and the first conductive sheet extends along the circumference of the first outer cover portion 101 to form an arc-shaped conductive sheet. The first output contact 9032 is a second conductive sheet fixed to the bottom side of the first outer cover portion 101, and the second conductive sheet extends along the circumference of the first outer cover portion 101 to form an arc-shaped conductive sheet. The second output contact 904 is a third conductive sheet fixed to the top side of the second outer cover portion 301, and the third conductive sheet extends along the circumference of the second outer cover portion 301 to form an arc-shaped conductive sheet. The second input contact 905 is a fourth conductive sheet fixed to the top side of the second outer cover portion 301, and the fourth conductive sheet extends along the circumference of the second outer cover portion 301 to form an arc-shaped conductive sheet. When used in conjunction with a spring pin in the screw-on installation of the cup lid, it can form a long continuous connecting spiral segment. That is, when the cup lid is not fully tightened, and the juicing process causes the cup lid to move slightly into / out of the cup body, the arc-shaped conductive plate can maintain the connection state to a large extent, making it less likely to disconnect the detection circuit, and thus better ensuring the stability of the detection.

[0049] In this embodiment of the invention, the identification unit 903 includes a resistive element, such as a resistor, connected in series with the first input contact terminal 9031 and the first output contact terminal 9032 with a specified resistance value.

[0050] After the detection circuit 9 is connected, the voltage value output by the detection voltage output terminal Vout of the main controller 4 changes after passing through the identification unit 903, and the corresponding change voltage value is obtained at the detection voltage feedback terminal Vin of the main controller 4.

[0051] The change in voltage value can be obtained by setting the resistance value of a resistive element. That is, by setting a resistive element with a specified resistance value, the main controller's detection voltage feedback terminal Vin can obtain the specified change in voltage value.

[0052] For example, when the voltage output value of the detection voltage output terminal Vout is 5V, the specified resistance value of the resistive component can be 10kΩ.

[0053] In this embodiment of the invention, the positioning switch 8 is a push-button positioning switch. That is, when the lower neck 203 is screwed into the second outer cover 301, the pressing contact of the positioning switch 8 is pressed down by the bottom side of the lower neck 203. After the lower neck 203 is screwed into place (meaning the cup body 2 is installed in place on the cup holder 1), the pressing contact of the positioning switch 8 is pressed down and the positioning switch 8 is in the triggered state.

[0054] like Figure 10As shown, the position switch 8 is set on the grounding terminal GND of the main controller, which constitutes an on / off switch. The trigger state indicates that the position switch is in the on state, and the grounding terminal GND of the main controller can be connected to the ground wire, thereby energizing and working. At this time, the main controller 4 is energized and works in the first control mode.

[0055] like Figure 7 As shown, the position switch 8 corresponds to the bottom side of the lower bottleneck 203.

[0056] To prevent leakage, a sealing ring 10 is provided between the position switch 8 and the lower neck 203. The sealing ring 10 is located inside the second outer cover 301. After the lower neck 203 is screwed into place, the lower neck 203 presses the sealing ring 10, and the sealing ring 10 presses down the pressing contact of the position switch 8 into place.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
