Description

Technical Field

[0001] This utility model relates to the field of household appliances, and more specifically, it relates to a lifting structure for an orange dispenser. Background Technology

[0002] Orange juicer usually refers to a small kitchen appliance specifically designed for extracting orange juice, and is a sub-type of juicer.

[0003] The working principle of an orange pressing machine is mainly based on mechanical pressing. The orange is cut horizontally in half, with the cut side facing down and aligned with the conical pressing head. Then, the lifting structure of the orange pressing machine moves the conical pressing head upward, thereby squeezing the orange and extracting the juice. When the conical pressing head reaches the upper limit position, the lifting structure then moves the conical pressing head downward until it reaches the lower limit position. Currently, orange pressing machines are equipped with upper limit sensors and lower limit sensors. The upper limit sensor is used to ensure that the pressing head does not rise excessively when squeezing the orange, and the lower limit sensor is used to ensure that the pressing head is completely reset. However, setting two sensors increases the assembly difficulty of the orange pressing machine, as the upper and lower limit wiring needs to be distinguished during the assembly process.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lifting structure for an orange machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a lifting structure for an orange machine, including a machine body and a conical pressing head, wherein a threaded sleeve is provided in the machine body, an internal threaded channel is provided on the inner peripheral wall of the threaded sleeve, a lifting column is provided in the threaded sleeve and threadedly connected to the internal threaded channel, the conical pressing head is fixedly connected to the top of the lifting column, and a drive motor for driving the lifting column to rotate is also provided in the machine body;

[0007] The lifting column includes an upper cylindrical section, an external threaded section, and a lower cylindrical section. The external threaded section is located between the upper and lower cylindrical sections. A micro switch is provided on the outer wall of the threaded sleeve. The micro switch includes a contact point that is inserted into the internal threaded channel. The external threaded section can push the contact point outward to disconnect the micro switch. When the micro switch is connected, the micro switch controls the drive motor to change its rotation direction.

[0008] The present invention is further configured such that: a square groove is provided at the lower end of the lifting column, and a square rod is provided inside the machine body that is always located in the square groove; a drive gear is fixedly connected to the lower end of the square rod, and the drive motor drives the drive gear to rotate, thereby realizing the movement of the lifting column.

[0009] The present invention is further configured such that: the number of the threaded sleeve, the lifting column and the square rod are all two, the drive motor drives the two lifting columns to rotate synchronously, and the micro switch is only set on one of the threaded sleeves.

[0010] The present invention is further configured such that: the machine body is provided with a drive gear and two transmission gears, the two transmission gears respectively mesh with two drive gears, the drive gear meshes with both transmission gears, and the drive motor drives the drive gear to rotate.

[0011] The present invention is further configured such that an abutment block is fixedly connected to one end of the contact point facing the lifting column.

[0012] The present invention is further configured such that the contact block is made of wear-resistant material.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By dividing the lifting column into an upper cylindrical section, an external threaded section, and a lower cylindrical section, when the positions of the upper and lower cylindrical sections correspond to the contact point, the contact point will retract into the internal threaded channel, and the micro switch will be activated, thereby changing the direction of movement of the lifting column. This design allows the lifting column to be controlled with a single sensor switch, reducing the number of sensors compared to existing technologies, simplifying wiring and assembly, and making it less prone to wiring errors. Furthermore, the reduction in the number of sensors also lowers the cost of the orange machine. With two lifting columns, two halves of oranges can be juiced simultaneously, improving the juicing efficiency of the machine, while the number of micro switches remains unchanged.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] The lifting structure of the orange machine, such as Figure 1 and Figure 2 As shown, the machine includes a body 1 and a conical press head 2. The outer peripheral wall of the conical press head 2 is provided with several protruding ridges. A threaded sleeve 3 is provided inside the body 1. An internal threaded channel 4 is provided on the inner peripheral wall of the threaded sleeve 3. A lifting column 5 is provided inside the threaded sleeve 3 and is threadedly connected to the internal threaded channel 4. The conical press head 2 is fixedly connected to the top of the lifting column 5. A drive motor 6 is also provided inside the body 1 to drive the lifting column 5 to rotate. The drive motor 6 can rotate in both directions. By driving the lifting column 5 to rotate, the drive motor 6 can enable the lifting column 5 to move up and down inside the threaded sleeve 3. During the up and down movement of the lifting column 5, it can drive the conical press head 2 to move up and down, and the conical press head 2 can rotate during the movement, thereby realizing the function of squeezing oranges and completing the juicing function of the orange machine.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the lifting column 5 includes an upper cylindrical section 7, an external threaded section 8, and a lower cylindrical section 9. The external threaded section 8 is located between the upper cylindrical section 7 and the lower cylindrical section 9. A micro switch is provided on the outer wall of the threaded sleeve 3. The micro switch includes a contact point 10 that inserts into the internal threaded channel 4. The external threaded section 8 can push the contact point 10 outward, causing one end of the contact point 10 to leave the internal threaded channel 4, thereby disconnecting the micro switch. When one end of the contact point 10 is inside the internal threaded channel 4, the micro switch is connected. When the micro switch is connected, it controls the drive motor 6 to change its rotation direction. When not being contacted, contact point 10 can automatically extend into the internal threaded channel 4. Specifically, the initial state of the lifting column 5 is when the uppermost thread of the external threaded section 8 abuts against contact point 10. At this time, an orange can be placed on the conical press head 2. After pressing the start button, the drive motor 6 drives the lifting column 5 to rotate and move upward, and the orange begins to be squeezed. During this time, contact point 10 is constantly abutted by the external threaded section 8. When the lifting column 5 moves upward to the limit position, the position of the lower cylindrical section 9 is aligned with contact point 10, and at this time, contact point 10 no longer abuts against the external threaded section 8. Contact point 10 re-enters the internal threaded channel 4, the micro switch is activated and sends an electrical signal to the control chip inside the body 1. The control chip can then control the drive motor 6 to reverse, causing the lifting column 5 to move downwards, thus preventing the lifting column 5 from exceeding its upper limit position. The lifting column 5 moves downwards until the position of the upper cylindrical section 7 aligns with the position of contact point 10. At this point, contact point 10 is no longer in contact, and it re-enters the internal threaded channel 4. The micro switch is activated and sends an electrical signal to the control chip inside the body 1, allowing the control chip to control the drive motor 6 to reverse... The rotation causes the lifting column 5 to move upward. When the external thread section 8 just touches the contact point 10, it indicates that the lifting column 5 has returned to its initial state, thus ending the juicing process. People can then remove the juiced oranges from the conical juicing head 2. The movement of the lifting column 5 can be controlled by a single microswitch, ensuring that the lifting column 5 does not move upward beyond the limit position and can also reset the lifting column 5. Compared with existing technologies, the single microswitch reduces the number of sensors, making wiring and assembly easier and reducing the likelihood of incorrect wiring. Furthermore, the reduction in the number of sensors also lowers the cost of the orange machine.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, a square groove 11 is provided at the lower end of the lifting column 5. A square rod 12, which is always located within the square groove 11, is provided inside the body 1. A drive gear 13 is fixedly connected to the lower end of the square rod 12. The drive motor 6 drives the drive gear 13 to rotate, thereby realizing the movement of the lifting column 5. During the rotation of the drive gear 13, the square rod 12 can be driven to rotate, and the square rod 12 can drive the rotation of the lifting column 5. During the movement of the lifting column 5, the position of the square rod 12 in the vertical direction remains unchanged, and the lifting column 5 can realize vertical movement. Threaded sleeve 3 There are two lifting columns 5 and two square rods 12. The drive motor 6 drives the two lifting columns 5 to rotate synchronously. The micro switch is only set on one threaded sleeve 3. There are two lifting columns 5 and two conical pressing heads 2 connected to the lifting columns 5. This setting allows oranges cut in half to be placed on the two conical pressing heads 2 for juicing, improving the juicing efficiency. Since the two lifting columns 5 move synchronously as a whole, only one micro switch is needed, which will not increase the number of controllers in the machine body 1.

[0024] like Figure 1 and Figure 4 As shown, the machine body 1 is equipped with a drive gear 14 and two transmission gears 15. The two transmission gears 15 mesh with two drive gears 13 respectively. The drive gear 14 meshes with both transmission gears 15. The drive motor 6 drives the drive gear 14 to rotate. The output shaft of the drive motor 6 is fixedly connected to the transmission gears 15 that mesh with the drive gear 14. Therefore, during the rotation of the drive motor 6, the drive gear 14 can rotate and drive the transmission gears 15 on both sides to rotate. The two transmission gears 15 mesh with the two drive gears 13 respectively, thereby realizing the synchronous rotation of the two lifting columns 5. The contact point 10 is fixedly connected to the end facing the lifting column 5 with a contact block 16, which is made of wear-resistant material. In this embodiment, the wear-resistant material can be POM plastic material. The contact block 16 itself has good wear resistance, which can ensure the life of the contact point 10 and the contact position of the lifting column 5. The micro switch includes a protrusion with rebound performance. In the normal state, the protrusion protrudes outside the micro switch. The protrusion abuts against the contact point 10 and inserts the contact block 16 into the internal thread channel 4. At this time, the micro switch is in the on state. When the contact block 16 abuts against the external thread section 8, the contact point 10 will move towards the micro switch and abut against the protrusion. At this time, the micro switch is off. When the contact block 16 does not abut against the external thread section 8, under the action of the elastic return of the protrusion, the contact block 16 will re-insert into the internal thread channel 4.
