Abstract
Description
Technical Field
[0001] This utility model relates to food machinery, and more particularly to a multi-functional vegetable slicer for slicing vegetables, fruits and vegetables. Background Technology
[0002] The motor of the multi-functional vegetable cutter needs to stop rotating when the pressure block is opened; when cutting vegetables with the pressure block closed, the motor runs normally. The specific control of the motor's stop and start is as follows: From Figure 6 , Figure 7 , Figure 8 , Figure 9 As can be seen, turning the handle causes the pressure block to move away from the feed inlet, allowing food to be placed in. At this time, the arc R below the pressure block handle rotates around the center of rotation. Since the center of arc R is lower than the center of rotation of the pressure block handle, when the pressure block handle rotates, the position of arc R, which contacts the spherical surface at the upper end of the contact rod, moves upward, causing the lower contact rod to move upward under the action of the spring. The magnet sleeve connected to the lower end of the contact rod causes the magnet to move upward as well, triggering the magnetic sensor below (not shown in the figure) to cut off the power to the motor, stopping the motor from rotating and the blade from cutting vegetables. Figure 3 As shown, when the handle is rotated in the reverse direction to its original position, the magnet moves downward with the contact rod. When the pressure block completely blocks the feed inlet, the magnet triggers the magnetic sensor below, activating the motor's power supply. The motor then starts rotating, driving the blades to cut the vegetables. It can be seen from the above that in existing vegetable cutters, the center of the contact rod and the center of the arc R both pass through the rotation center of the pressure block handle, resulting in a relatively small axial travel of the contact rod during rotation.
[0003] Because the magnetic sensor has limited sensitivity, it must move the magnet a certain distance before it starts to switch on or off. If the distance the contact rod moves is too small, the magnetic sensor will not switch on or off, causing control failure. This requires the contact rod to have a reasonable stroke when the pressure block handle is turned. As a result, existing vegetable cutters often have difficulty in debugging and may even experience control failure later on. Summary of the Invention
[0004] The problem this invention aims to solve is to provide a multi-functional vegetable cutter with reliable motor start-stop. It significantly increases the travel of the contact rod by changing the relative position of the contact rod and the pressure block handle, as well as the position of the arc on the pressure block handle. Simultaneously, the unequal-distance double-eccentric structure accelerates the initial lifting speed of the contact rod, thus improving the ease of adjustment and reliability of the magnetic sensor switch, and ensuring reliable motor start-stop.
[0005] This utility model discloses a multi-functional vegetable cutter with reliable motor start-stop, comprising a handle, a pressing block, a connecting pin, a feeding box, and a machine body. It also includes a pressing block handle and a contact rod. The handle passes through a connecting hole at the top of the pressing block handle and connects to the pressing block. The middle part of the pressing block handle is located between the front and rear connecting plates on the left side of the feeding box. The connecting pin engages with the pin hole in the middle of the pressing block handle and connects to the feeding box. The contact rod is mounted on a mounting base on the left side of the feeding box and is located below the pressing block handle. The lower surface of the pressing block handle is a combination of an arc surface R and a plane L. The center of the arc surface R is offset to the right relative to the vertical plane of the center of the pin hole of the pressing block handle. The plane L is tangent to the arc surface R. The center of the contact rod is offset to the right relative to the vertical plane of the center of the pin hole of the pressing block handle. The spherical surface at the top of the contact rod contacts the arc surface R of the pressing block handle.
[0006] Furthermore, the offset of the center of the contact rod relative to the vertical plane of the pin hole center of the pressure block handle is A, and the offset of the center of the arc surface R of the pressure block handle relative to the vertical plane of the pin hole center of the pressure block handle is B, where B = A.
[0007] Furthermore, the offset of the center of the contact rod relative to the vertical plane of the pin hole center of the pressure block handle is A, and the offset of the center of the arc surface R of the pressure block handle relative to the vertical plane of the pin hole center of the pressure block handle is B, where B > A.
[0008] Furthermore, the multifunctional vegetable cutter of this utility model also includes a spring, a pressure sleeve, a magnetic sleeve, and a magnet. The pressure sleeve is connected to the lower end of the sleeve of the contact rod. The spring is sleeved on the small shaft of the contact rod, and its upper and lower ends are in contact with the stepped surface of the rod and the pressure sleeve. The magnetic sleeve and the magnet are both located in the mounting seat on the left side of the feed box. The upper and lower parts of the magnetic sleeve are connected to the rod of the contact rod and the magnet, respectively.
[0009] The advantages of this multi-functional vegetable cutter are: 1. By simultaneously moving the pressure block handle and the contact rod to the right, closer to the machine body, the distance the contact rod moves is increased, thus providing a reasonable stroke for the contact rod. This makes the magnetic sensor easy to adjust and ensures reliable switching control, guaranteeing reliable stopping and starting of the motor. 2. The offset of the center of the contact rod relative to the vertical plane of the pin hole center of the pressure block handle is A, and the offset of the center of the arc surface R of the pressure block handle relative to the vertical plane of the pin hole center of the pressure block handle is B. When B > A, the contact point of the contact rod and the arc R of the pressure block handle shifts to the left, resulting in a certain angle between the common tangent of the contact between the spherical surface on the contact rod and the arc surface on the pressure block handle. This increases the initial lifting speed of the contact rod, allowing the magnetic sensor to detect the movement of the contact rod earlier, thereby reliably controlling the switching and protecting the reliable stopping and starting of the motor.
[0010] In summary, this utility model of a multi-functional vegetable cutter significantly increases the travel of the touch rod by changing the relative position of the touch rod and the pressure block handle, as well as the position of the arc on the pressure block handle. At the same time, the unequal-distance double eccentric structure accelerates the initial lifting speed of the touch rod, thus improving the convenience and reliability of the magnetic sensor switch adjustment and ensuring reliable stopping and starting of the motor.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As can be seen, this utility model discloses a multi-functional vegetable cutter with reliable motor start and stop, which includes a handle 1, a pressing block 2, a connecting pin 4, a feeding box 6, and a machine body 11. It also includes a pressing block handle 3 and a contact rod 5. The handle 1 passes through the connecting hole at the top of the pressing block handle 3 and connects to the pressing block 2. The middle part of the pressing block handle 3 is located between the front and rear connecting plates on the left side of the feeding box 6. The connecting pin 4 engages with the pin hole in the middle of the pressing block handle 3 and connects to the feeding box 6. The contact rod 5 is installed on the mounting base on the left side of the feeding box 6 and is located below the pressing block handle 3. The lower surface of the pressing block handle 3 is a combination of an arc surface R and a plane L. The center of the arc surface R is offset to the right relative to the vertical plane of the pin hole center of the pressing block handle 3. The plane L is tangent to the arc surface R. The center of the contact rod 5 is offset to the right relative to the vertical plane of the pin hole center of the pressing block handle 3. The spherical surface at the top of the contact rod 5 contacts the arc surface R of the pressing block handle 3.
[0025] This utility model of a multi-functional vegetable cutter: the center of the arc surface R of the pressing handle 3 is moved to the right, which extends the arc length of the arc surface R. The center of the contact rod 5 is moved to the right, which extends the contact length between the contact rod 5 and the arc R. Therefore, when both the pressing handle 3 and the contact rod 5 move to the right at the same time, they approach the feeding box 6, which increases the distance the contact rod 5 moves and greatly improves the stroke of the contact rod. This makes it easy to adjust the magnetic sensor. At the same time, the magnetic sensor can reliably control the switch, ensuring reliable stopping and starting of the motor.
[0026] Example 2
[0027] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that in this utility model of multifunctional vegetable cutter: the offset of the center of the contact rod 5 relative to the vertical plane of the pin hole center of the pressure block handle 3 is A, and the offset of the center of the arc surface R of the pressure block handle 3 relative to the vertical plane of the pin hole center of the pressure block handle 3 is B, B=A.
[0028] When B=A, the center of the arc surface R of the pressure block handle 3 and the center of the contact rod 5 are on the same vertical plane. At this time, the pressure block handle 3 rotates, which greatly extends the contact length between the contact rod and the arc R and increases the distance the contact rod moves, thereby ensuring that the magnetic sensor can operate reliably.
[0029] Example 3
[0030] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5It can be seen that in this utility model of multifunctional vegetable cutter: the offset of the center of the contact rod 5 relative to the vertical plane of the pin hole center of the pressure block handle 3 is A, and the offset of the center of the arc surface R of the pressure block handle 3 relative to the vertical plane of the pin hole center of the pressure block handle 3 is B, where B > A.
[0031] When B = A, the common tangent of the contact between the spherical surface on the contact rod 5 and the arc surface on the pressure block handle 3 is horizontal, resulting in a slower initial speed increase of the contact rod. Therefore, as an improvement of this utility model, when B > A, the contact starting point of the arc R between the contact rod 5 and the pressure block handle 3 is shifted to the left, so that the direction of the common tangent of the contact between the spherical surface on the contact rod 3 and the arc surface on the pressure block handle 3 has a certain angle, which increases the initial lifting speed of the contact rod, allowing the magnetic sensor to detect the movement of the contact rod as early as possible, thereby reliably controlling the switch and protecting the reliable stopping and starting of the motor.
[0032] Example 4
[0033] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that the multifunctional vegetable cutter of this utility model also includes a spring 7, a pressure sleeve 8, a magnet sleeve 9, and a magnet 10. The pressure sleeve 8 is connected to the lower end of the sleeve of the contact rod 5. The spring 7 is sleeved on the small shaft of the rod of the contact rod 5, and its upper and lower ends are in contact with the stepped surface of the rod and the pressure sleeve 8. The magnet sleeve 9 and the magnet 10 are both located in the mounting seat on the left side of the feed box 6. The upper and lower parts of the magnet sleeve 9 are connected to the rod of the contact rod 5 and the magnet 10, respectively.
[0034] The control of the motor's stop and start in this multifunctional vegetable cutter is as follows: Rotating the handle causes the pressure block to move away from the feed inlet. The pressure block handle rotates counter-clockwise, causing the lower arc R, which contacts the upper spherical surface of the contact rod, to move upwards. The contact rod moves upwards under the action of a spring, causing the magnet sleeve to move the magnet upwards as well. This triggers the magnetic sensor below, cutting off the motor's power supply, stopping the motor's rotation, and stopping the blades from cutting vegetables. When food is placed in, rotating the handle in the opposite direction causes the pressure block to return to its original position. At this time, the pressure block handle rotates counter-clockwise, causing the lower arc R, which contacts the upper spherical surface of the contact rod, to move downwards, pressing the contact rod downwards. The magnet sleeve moves the magnet downwards as well, triggering the magnetic sensor below, starting the motor's power supply. When the pressure block completely blocks the feed inlet, the magnet motor starts rotating, driving the blades to begin cutting vegetables. Pressing the handle downwards causes the handle to move the pressure block downwards, pressing down on vegetables and fruits, which then move downwards and enter the blade position to be cut into the desired slices, shreds, or cubes.
[0035] The advantages of this multi-functional vegetable cutter are: 1. By simultaneously moving the pressure block handle and the contact rod to the right, closer to the machine body, the distance the contact rod moves is increased, thus providing a reasonable stroke for the contact rod. This ensures that the magnetic sensor can reliably control the switch, protecting the motor and ensuring reliable stopping and starting. 2. The offset of the center of the contact rod relative to the vertical plane of the pin hole center of the pressure block handle is A, and the offset of the center of the arc surface R of the pressure block handle relative to the vertical plane of the pin hole center of the pressure block handle is B. When B > A, the contact starting point of the contact rod and the arc R of the pressure block handle shifts to the left, so that the direction of the common tangent of the contact between the spherical surface on the contact rod and the arc surface on the pressure block handle has a certain angle. This increases the initial lifting speed of the contact rod, allowing the magnetic sensor to detect the movement of the contact rod as early as possible, thereby reliably controlling the switch and ensuring reliable stopping and starting of the motor.
[0036] In summary, this utility model of a multi-functional vegetable cutter significantly increases the travel of the touch rod by changing the relative position of the touch rod and the pressure block handle, as well as the position of the arc on the pressure block handle. At the same time, the unequal-distance double eccentric structure accelerates the initial lifting speed of the touch rod, thus improving the convenience and reliability of the magnetic sensor switch adjustment and ensuring reliable stopping and starting of the motor.
[0037] The following describes one specification of our product: When the radius of the arc surface R of the pressure block handle is 16mm and the spherical surface SΦ of the contact rod is 4.6: The structure in the background technology is as follows Figure 11 As shown, the stroke of the contact rod at its lowest and highest positions is 35-33.65=1.35mm; the improved structure of this utility model is as follows. Figure 10 As shown, the center of the arc R16 is offset by 5mm relative to the rotation center of the pressure block handle, and the center of the contact rod is offset by 3mm. The stroke of the contact rod is 34.9-28.42=6.48mm. It can be seen from the above that the stroke of the contact rod in this utility model is increased by 6.48-1.35=5.13mm compared with the previous version. The increase meets the requirements of the magnetic sensor, ensuring that the sensor is reliable and sensitive, thereby ensuring the reliable start and stop of the motor.
