Description

[0002] There are many types of juicers on the market, and orange squeezers for squeezing orange juice are one of them. However, the applicant has found that many orange squeezers still have one or another deficiency, such as:

[0003] 1. The motor, reducer and shaft are installed as a whole in the orange squeezer and move up and down synchronously. This not only requires a large internal space for the orange squeezer, but also the wiring harness connected to the motor is prone to wiring harness fatigue or wiring harness twisting during the movement, which increases the motor load and reduces the service life. The energy consumption of the orange squeezer is high;

[0004] 2. An upper limit switch and a lower limit switch are set on the casing of the orange squeezer to control the lifting and stopping during the juicing process. However, each lifting and lowering must be against the upper limit switch and the lower limit switch, causing the upper limit switch and the lower limit switch to become loose and have poor contact, and finally the juice cannot be squeezed;

[0005] 3. The rotating shaft will shake due to the long moving distance, causing the orange juice to seep into the motor through the end of the shaft and burn;

[0006] 4. The operation of the juicer involves many steps and its intelligence level is low.

[0007] Therefore, it is necessary to improve or design an orange squeezer that can realize automatic juice squeezing by electronically controlling the lifting and lowering, and has simple operation and stable structure. Summary of the invention

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] To achieve the above-mentioned purpose, the embodiment of the present invention provides an orange squeezer with an electric control lifting and squeezing function, referring to Figure 1-6 As shown, including:

[0045] A main housing 5, a transmission housing 1 is fixedly provided on the inner side of the bottom of the main housing 5, a gear reducer 2 is installed in the transmission housing 1, a motor 3 and a rotating shaft 12 are provided on the transmission housing 1, and the motor 3 is located on one side of the rotating shaft 12 and is facing upward;

[0046] A cup body 6, wherein the cup body 6 is disposed at the upper end of the main housing 5, and the lower end of the cup body 6 is detachably connected to the upper end of the main housing 5 by a buckle;

[0047] A juice extraction component 32, wherein the juice extraction component 32 is disposed in the cup body 6;

[0048] The lifting assembly 4 includes a sleeve 10 and a lifting rod 11. The bottom end of the sleeve 10 is fixedly mounted on the transmission box 1. The lifting rod 11 is rotatably threaded in the sleeve 10. The rotating shaft 12 is slidably sleeved in the lifting rod 11. The rotating shaft 12 is connected to the gear reducer 2. The upper end of the lifting rod 11 is connected to the juice extraction assembly 32.

[0049] The locking limit assembly 30 includes a locking guide ring 16 and a locking convex ring 29. The upper end of the sleeve 10 is provided with a locking guide ring 16, and the transmission box body 1 is provided with a locking convex ring 29. The locking convex ring 29 is located directly below the lifting rod 11;

[0050] An integrated circuit control device, the integrated circuit control device includes a control board and an IC chip 31, the control board is fixedly mounted on one side of the main housing 5, the IC chip 31 is embedded on the control board, the IC chip 31 is used to control the operation of the motor 3, and the control board is electrically connected to the motor 3;

[0051] Among them, when the lifting rod 11 rises and collides with the locking guide ring 16, the IC chip 31 receives the locking current signal, and the motor 3 drives the lifting rod 11 to rise to the first limit height H1. When the lifting rod 11 descends and collides with the locking convex ring 29, the IC chip 31 receives the locking current signal, and the motor 3 drives the lifting rod 11 to descend to the second limit height H2, wherein H1>H2, and H1 and H2 are both greater than 0.

[0052] The main technical solution of the present invention is to control the operation of the motor 3 with an integrated circuit control device, and drive the rotating shaft 12 to rotate through the gear reducer 2. The lifting rod 11 is slidably sleeved on the rotating shaft 12 and rotated, and the lifting rod 11 and the sleeve 10 are connected by the screw transmission principle to realize the rise and fall of the lifting rod 11. In the process of the lifting rod 11 rising or falling, the lifting rod 11 is restricted from rotating out of the sleeve 10 by correspondingly setting a locking guide ring 16 and a locking convex ring 29, so that the IC chip 31 can receive the locking current signal and send corresponding operation instructions to the motor 3, thereby realizing one-click intelligent juice extraction of the juicer.

[0053] In this embodiment, the transmission box 1 is fixed on the inner side of the bottom of the orange squeezer body, so as to avoid the problems of harness twisting, large space volume, large load on the motor 3, short service life and the like caused by the up and down movement of the transmission box 1, and play the role of stabilizing the motor 3 and the lifting assembly 4. Through the connection between the gear reducer 2, the motor 3 and the lifting assembly 4, the motor 3 drives the lifting rod 11 to rotate and rise, and the food is rotated and lifted and twisted to squeeze the food to produce juice, wherein the food can be various fruits (apples, pears, oranges, etc.) or vegetables (cucumbers, carrots, etc.). The IC chip 31 controls the motor 3 to reverse and drive the lifting rod 11 to rotate and descend and reset. The juice extraction assembly 32 is used to put food in for juicing or take out the food residue and pour it out. The integrated circuit control device controls the motor 3 to drive the lifting rod 11 to rise to the first limit height H1 or to fall to the second limit height H2, so as to solve the problem that the traditional micro switch takes up space and is easy to touch poorly. The modified machine optimizes the structure of the juicer and realizes the advantages of automatic lifting, stability and reliability and high juice yield.

[0054] In an optional embodiment, the locking guide ring 16 can be designed as a locking guide ring 16 with elastic function or a locking guide ring 16 with non-elastic function, and the locking convex ring 29 can be designed as a locking convex ring 29 with elastic function or a locking convex ring 29 with non-elastic function.

[0055] For further reference, Figure 4 As shown, the inner wall of the sleeve 10 is provided with an internal thread, and the bottom of the lifting rod 11 is provided with an external thread 14 that cooperates with the internal thread. When the upper end surface of the external thread 14 of the lifting rod 11 rotates and rises to abut against the bottom end surface of the blocking guide ring 16, the lifting rod 11 cannot continue to rise. At this time, the control board generates a current blocking, and obtains a blocking current signal through the IC chip 31 to control the motor 3 to stop running and wait for the next running instruction; when the lower end surface of the external thread 14 of the lifting rod 11 descends and abuts against the upper end surface of the blocking convex ring 29, the lifting rod 11 cannot continue to descend. At this time, the control board also generates a current blocking, and obtains a blocking current signal through the IC chip 31 to control the motor 3 to stop running and wait for the next running instruction.

[0056] Specifically, the IC chip 31 is used to control the operation of the motor 3 including forward rotation, stop rotation, delay rotation and reverse rotation as follows:

[0057] When the power is turned on, the IC chip 31 controls the motor 3 to rotate forward, so that the lifting rod 11 rises;

[0058] When the IC chip 31 receives a current value exceeding the first preset stall current threshold, it obtains a stall current signal and sends a stall command to the motor 3. At this time, the current height to which the lifting rod 11 rises is recorded as L, and H2<L≤H1;

[0059] When the IC chip 31 receives a signal indicating that the delay time of the motor 3 exceeds the preset delay time, a reverse command is sent to the motor 3, and the lifting rod 11 moves downward;

[0060] When the current value received by the IC chip 31 exceeds the second preset stall current threshold, a stall current signal is obtained, and a stall command is issued to the motor. At this time, the lifting rod 11 descends to the H2 position.

[0061] For example, in an optional embodiment, the cleaned food is placed in the juice extraction component 32, the power is turned on, and the IC chip 31 controls the motor 3 to rotate forward to drive the lifting rod 11 to rise and push the juice extraction component 32 to extract juice; when the lifting rod 11 is difficult to rise, the control board will generate a current stall, and when the stall current value exceeds the first preset stall current threshold, the IC chip 31 obtains the stall current signal and sends a stop command to the motor 3, and waits for the next operation command. At this time, the current height to which the lifting rod 11 rises is recorded as L, for example, L=10 0cm; when the waiting delay time of the motor 3 exceeds the preset delay time (for example, 0.5 seconds), a reverse command is issued to the motor 3 to make the lifting rod 11 descend and run; when the lifting rod 11 descends to the point where its external thread 14 conflicts with the locking convex ring 29, the control board will generate a current lock. When the locking current value exceeds the second preset locking current threshold, the IC chip 31 obtains the locking current signal and issues a stop command to the motor 3. At this time, the lifting rod 11 descends to the H2 position. For example, H2=-20cm, and "-" is a minus sign, indicating a direction.

[0062] It can be known that, during the process of juicing the ingredients by the juicing component 32, since the ingredients occupy a certain space, when the lifting rod 11 rises for the first time to squeeze the juice, its external thread 14 may not be able to resist the stall guide ring 16 and reach a certain rising limit. At this time, the control board will also generate current stall. When the stall current value exceeds the first preset stall current threshold, the IC chip 31 obtains the stall current signal and sends a stop command to the motor 3.

[0063] Among them, the current height L to which the lifting rod 11 rises includes L1, L2, L3...LN, N represents the number of times, L1, L2, L3...LN is the current height reached by the juice extraction component 32 each time the juice is extracted and touches the first preset stall current threshold. When N=preset number of repetitions or when L=H1, the IC chip 31 controls the motor 3 to reverse so that the lifting rod 11 is reset to the H2 position and stops.

[0064] It should be noted that when the motor 3 repeats forward rotation, stop rotation, delay and reverse rotation for a complete juicing operation, if the number of instructions reaches the preset number, the IC chip 31 controls the motor 3 to stop. Of course, for ingredients that are easier to juice, a complete juicing operation can be stopped immediately.

[0065] For further reference, Figure 2-3 As shown, the juice extraction assembly 32 includes a juice extraction plate 7 and a pressure plate cover 8, the pressure plate cover 8 is arranged on the upper end of the cup body 6 and is detachably connected with the cup body 6 by snapping, the pressure plate cover 8 is provided with a cup cover 9, the cup body 6 is provided with a juice extraction plate 7, and the bottom of the juice extraction plate 7 is connected with the upper end of the lifting rod 11. Preferably, the snap connection can be to set a groove body 27 on the main housing 5 and the pressure plate cover 8, and to set a protruding block 28 on the upper and lower ends of the cup body 6, and to use the protruding block 28 to be detachably inserted into the groove body 27 and tightly buckled. Of course, the snap connection can also be to set a protruding block 28 on the main housing 5 and the pressure plate cover 8, and to set a groove body 27 on the upper and lower ends of the cup body 6, and then snap-fit ​​and buckle.

[0066] For further reference, Figure 2-3 As shown, the top of the juice extracting plate 7 is provided with a piercing tip 20, which is convenient for piercing and fixing the food. The juice extracting plate 7 is provided with a plurality of juice filtering holes 21, and the juice flows into the cup body 6 after being discharged. The inner side of the pressing plate cover 8 is provided with a plurality of raised tips 22, which can resist and prevent the food from sliding and falling.

[0067] Among them, the lifting rod 11 is a hollow tube with an opening at the bottom, which is used for sliding connection and sleeved on the rotating shaft 12, and has an anti-foolproof arrangement between the rotating shaft 12. The upper end of the lifting rod 11 is provided with an anti-foolproof portion 15. The structure of the anti-foolproof portion 15 can be that the upper end cross-section of the lifting rod 11 is processed into a hexahedron, a tetrahedron or an arc-cut half and other movable connection shapes. A socket is provided at the bottom of the juice extraction plate 7 (not marked in the drawing), and the anti-foolproof portion 15 is connected with the socket. The lifting rod 11 is rotated up and down, and the juice extraction plate 7 is driven to rotate up and down under the action of the anti-foolproof portion 15.

[0068] Furthermore, an outer side of the lower middle portion of the cup body 6 is provided with an integrally connected juice outlet 18 , and a flip-up end cover 19 is provided at the end of the juice outlet 18 .

[0069] For further reference, Figure 2 As shown, a sealing ring 17 is sleeved inside the blocking guide ring 16, and the inner wall of the sealing ring 17 is elastically pressed against the outer wall of the lifting rod 11 to prevent the juice from seeping down into the main housing 5, thereby ensuring the safety of the juicer.

[0070] For further reference, Figure 4 and Figure 6 As shown, a power supply device is provided in the main housing 5, and the power supply device includes a battery charging module and / or a plug-in module. A switch button 26 is provided on the side of the main housing 5, and the control panel is electrically connected to the power supply device and the switch button 26.

[0071] In an optional embodiment, the battery charging structure of the juicer may include a battery pack 24 disposed on one side of a control panel 23 and a charging interface 25 disposed on one side of the bottom of the main body, wherein the control panel 23 is electrically connected to the battery pack 24 and the charging interface 25 .

[0072] In this embodiment, when in use, the switch button 26 is pressed and held for 10 seconds to turn on the machine. The control panel 23 controls the motor 3 to rotate forward so that the lifting rod 11 rises to the first limit height H1, and the juice extraction plate 7 rotates and rises to press the food against the lower surface of the pressure plate cover 8, and continues to rotate to squeeze the food toward the pressure plate cover 8, and the food juice flows into the cup body 6. After that, the control panel 23 controls the motor 3 to reverse and make the lifting rod 11 descend to the second limit height H2, and the juice extraction plate 7 descends with the food residue. The operation can be repeated many times, and the food is fully juiced. Press the switch button 26 and hold for 3 seconds to automatically shut down the machine, open the end cover 19, pour the squeezed food juice out from the juice outlet 18, and take out and separate the food residue on the juice extraction plate 7.

[0073] refer to Figure 7 As shown, it is a schematic diagram of the circuit control structure of the electronically controlled lifting and squeezing juice of the present invention; the IC chip 31 is electrically connected to the forward / reverse switching circuit in the motor 3 driving circuit through the switch circuit, and the IC chip 31 is electrically connected to the forward / reverse switching circuit in the motor 3 driving circuit. A current reading circuit is arranged between the IC chip 31 and the forward / reverse switching circuit. In this way, the IC chip 31 receives the operation instruction of the switch circuit, and the operation instruction includes pressing the switch button 26 and staying for a few seconds (for example, 1 second, 2 seconds or 3 seconds) to turn on the machine, etc., and transmits the operation instruction to the forward / reverse switching circuit to wake up the motor 3 to rotate forward, and the lifting rod 11 rises. During this rising process, the current reading circuit detects and reads the current value in real time. In the process of the motor 3 rotating forward, when the current value exceeds the first preset stall current threshold value (for example, 25A), the forward / reverse switching circuit automatically switches the motor 3 to reverse rotation, and the lifting rod 11 descends until the current value read by the current reading circuit exceeds the second preset stall current threshold value (for example, 20A), and the IC chip 31 controls the motor 3 to rotate forward for 1 second and then stop or reset. When the motor 3 rotates forward for 1 second, it stops.
