Fig. 1 is a schematic view of a juice preparing apparatus according to an embodiment of the present invention, fig. 2 is a sectional view of the juice preparing apparatus of fig. 1, fig. 3 is a sectional view taken along a-a in fig. 2, and fig. 4 is an enlarged view of a portion I in fig. 3.
In this embodiment, the juice preparing apparatus includes a mounting base 100, a motor 310, a curved blade bar 400, a guard mechanism 500, and a safety switch mechanism 600. The motor 310 is fixed to the mounting base 100. The motor 310 includes a main shaft 200, and the main shaft 200 is a hollow shaft passing therethrough. Spindle 200 includes outlet section 210, mounting section 220, extension section 230, and tool mounting section 240, arranged in series. The main shaft 200 is coaxially fixed to a hollow shaft 313 of the motor 310 by the mounting section 220, and is fixed to the rotor 311 by the hollow shaft 313. The extension 230 and the tool mounting section 240 of the spindle 200 protrude outside the motor 310.
The bending blade bar 400 is fixed to the tool mounting section 240 of the main spindle 200 by one end, and a body portion between both ends of the bending blade bar 400 protrudes from the surface of the main spindle 200.
Both ends of the main spindle 200 protrude out of the mounting base body 100, and one end thereof is provided with a bent blade bar 400, i.e., the outlet section 210 partially protrudes from one end of the mounting base body 100, and the extension section 230 and the tool mounting section 240 protrude from the other end of the mounting base body 100. The revolving motion of the curved blade bar 400 around the spindle 200 when the spindle 200 rotates causes the curved blade bar 400 to form a revolving envelope surface protruding from the surface of the spindle 200.
In this embodiment, the main shaft 200 is a hollow shaft and can be used as a suction pipe.
The juice preparing apparatus further includes a main switch (not shown) provided on an outer surface of the mounting base 100 and actively operated by an operator to be turned on or off. The motor 310 can be rotated when the main switch and the safety switch 610 in the safety switch mechanism 600 are simultaneously in the on state.
When the fruit cutting machine is used, a user can insert one end of the main shaft 200, which is provided with the bent blade bar 400, into a fruit, then the motor 310 is started to drive the main shaft 200 to rotate, and the bent blade bar 400 can cut the surrounding pulp in the rotation process; the user holds the mounting base 100, stirs the end of the main shaft 200, at which the curved blade 400 is disposed, inside the fruit (continuously changes the angle and depth of the main shaft 200 entering the fruit), and cuts the pulp inside the fruit by the curved blade 400, thereby making the pulp into juice inside the fruit. In this embodiment, the main shaft 200 is a hollow shaft and corresponds to a suction pipe, so that juice can be directly sucked through the end of the main shaft 200 protruding out of the mounting base 100 after juice preparation.
The mounting base 100 is further provided with a sleeve 900, and the sleeve 900 is sleeved on the periphery of the outlet section 210 of the main shaft 200. The sleeve 900 surrounds the outlet section 210 of the main shaft 200 and does not rotate along with the main shaft 200, so that the main shaft 200 can be prevented from being in contact with human bodies or objects to cause tangling when rotating. The sleeve 900 may be in sealing contact with the outlet section 210 of the spindle 200 to prevent juice from entering the apparatus along the gap therebetween and to prevent air leakage from the gap therebetween during juice consumption. The sealing contact mode can be provided with a dynamic sealing ring and the like.
The juice preparing apparatus of the present embodiment will be described in detail below.
The mounting base 100 has a substantially cylindrical shape and is used to mount components such as a motor, a switch, and a circuit board, and the outer surface of the mounting base 100 is held by a user. The side wall of the mounting base 100 is also provided with a hole 130, the opening of the hole 130 is arranged on the end face of the mounting base 100, and the hole 130 is a blind hole. The side wall of the hole 130 is also provided with an opening, which is located near the orifice of the hole 130.
The driving installation part 120 is a cavity surrounded by a housing and having an opening at one end for the motor 310 to be placed in during an assembling process. In alternative embodiments, the drive mounting portion 120 may be provided without a cylindrical housing, with only one mounting plate, and the motor or other drive mechanism may be mounted on the mounting plate, as the motor generally has a relatively smooth outer surface, and may be held by an operator.
The side wall of the mounting base body 100 is further provided with a hole 130, the hole 130 is parallel to the axis of the spindle of the motor 310, the opening of the hole 130 is arranged on the end face of the mounting base body 100 and is the end face of the protruding end of the extending section 230, and the hole 130 is a blind hole. The sidewall of the hole 130 is also provided with an opening near the opening of the hole 130 for inserting the button of the switch in the safety switch mechanism 600 into the inside of the hole 130.
The main shaft 200 includes an outlet section 210, a mounting section 220, an extension section 230 and a cutter mounting section 240 which are sequentially arranged, and has a through inner cavity, and the main shaft 200 can be used as a suction pipe for sucking liquid. The spindle 200 in this embodiment is a unitary structure and may be machined from a tube or shaft piece. The outlet section 210 of the spindle 200 projects beyond an end of the mounting base 100 for a user to enter. The mounting section 220 is used for a fixed connection to the hollow shaft 313. The extension 230 and the cutter mounting section 240 protrude from the other end of the mounting base 100, and the cutter mounting section 240 is used for mounting the bent blade bar 400, and the bent blade bar 400 and the extension 230 and the cutter mounting section 240 can rotate and agitate in the fruit.
The tool mounting section 240 is used to secure the curved blade bar 400. The cutter mounting section 240 is a shaft body at the end of the main shaft 200, and the length of the shaft body can be set according to the diameter value of the fruit to be processed, for example, if the juice preparing device is used for processing oranges in this embodiment, the total length of the extension section 230 of the main shaft 200 and the cutter mounting section 240 is equal to or not less than the diameter of the oranges, and the length of the cutter mounting section 240 should be less than the diameter of the oranges, and can be set to be one third of the diameter of the oranges. The total length of the extension 230 and the cutter mounting section 240 may be set to be slightly larger than the diameter of the orange (a statistical value, which may be an average value or a median value, etc.), so that the bending blade 400 can be sufficiently deep inside the fruit.
The main shaft 200 in this embodiment is a cylindrical shaft, and in some alternative embodiments, the main shaft may also be a structure such as a quadrangular prism or a hexagonal prism. In this embodiment, the main shaft 200 is a hollow shaft, and can be used as a suction pipe, and in some alternative embodiments, the main shaft 200 can also be a solid shaft; in other alternative embodiments, the spindle 200 may also be provided without the outlet section 210, and juice may be sucked through the spindle by a suction tube; alternatively, main shaft 200 may also be a solid shaft without outlet section 210.
The curved blade bar 400 has two ends, a first end 410 and a second end 420, the curved blade bar 400 being secured to the tool mounting section 240 of the spindle 200 by the first end 410. In this embodiment, the curved blade bar 400 is an arc-shaped blade bar, and a plane where the arc-shaped blade bar is located passes through the axis of the spindle 200. The curved blade bar 400 is fixed on the circumferential surface of the tool mounting section 240 through one end, and the contact points of the two ends of the same curved blade bar 400 and the main shaft 200 are located on the same bus, and the arc-shaped tool body thereof protrudes out of the circumferential surface of the tool mounting section 240. When the main shaft 200 rotates, the curved blade 400 rotates along with the main shaft 200, and the area swept by the arc-shaped blade forms a spherical surface, that is, the curved blade 400 can form a revolution envelope surface protruding out of the surface of the main shaft 200 when rotating around the main shaft 200. The number of the curved blade bars 400 is 3 in this embodiment, and they are uniformly distributed around the main shaft 200. In the present embodiment, the plane of the curved blade strip 400 passes through the axis of the spindle 200, but in other embodiments, the plane of the curved blade strip 400 may be arranged to have a distance smaller than the radius of the spindle 200 from the axis of the spindle 200; or the plane of the bending blade strip 400 is arranged to form an included angle of less than 90 degrees with the axis of the main shaft 200, that is, two ends of the bending blade strip 400 are located on different generatrices of the main shaft 200.
The radius of gyration of the curved blade bar 400 is less than the fruit radius and may be, for example, one-third, one-fourth, or other value of the fruit radius. In this way, the fruit is only required to be provided with a hole having a diameter equivalent to the diameter of the curved blade 400 in rotation, and the curved blade 400 can enter the fruit with a small resistance and does not receive a large rotation resistance during rotation. Meanwhile, the provision of the extension 230 allows the curved blade bar 400 to be freely agitated within the fruit, and also more sufficiently treats the pulp within the fruit.
In some alternative embodiments, the curved blade bar 400 is a resilient blade bar. When the bending blade 400 is subjected to external force with certain magnitude, the bending blade deforms, and the radian of the bending blade can be changed, so that the size of the turning radius of the bending blade is changed. For example, when the bending blade 400 is pressed by the fruit peel, the blade body is pressed and deformed, the blade body approaches the main shaft 200, and the turning radius is reduced. When the bending knife strip 400 has proper rigidity, the bending knife strip cannot deform obviously when cutting pulp, but deforms when being extruded by pericarp with higher strength, so that damage to the pericarp can be reduced.
In alternative embodiments, the curved blade strip 400 may also have other shapes, such as a dog-leg shape including two bends, i.e., a trapezoidal shape with the lower base removed; of course, it may be a zigzag shape including more bending portions. In alternative embodiments, the curved blade bar 400 may also be in the shape of a space curve, such as a segment of a helix that may be at a larger lead angle.
The body of the curved blade bar 400 includes 4 faces, an outer surface 411, an inner surface 412, a first side 413, and a second side 414. The inner surface 412 is substantially parallel to the outer surface 411 and is closer to the spindle 200 than the outer surface 411. The first side 413 meets the inner surface 412 and forms an edge that is less than 90 degrees, and the second side 414 meets the inner surface 412 and forms an edge that is less than 90 degrees.
The blade formed between the inner surface 412 and the first side 413 and the blade formed between the inner surface 412 and the second side 414 are located between the outer surface 411 and the main shaft 200, and the cutting edge of the blade is not located on the outermost surface of the envelope of revolution, so that the blade is not easy to damage harder pericarp, and the blade can not significantly affect the cutting of softer pulp. Because the pulp is soft, the first side surface 413 and the second side surface 414 can extrude the pulp to a certain extent, so that the density of the extruded pulp is increased, and the pulp can be cut by the blade. Meanwhile, the first side 413 and the second side 414 can press out juice in the pulp when pressing the pulp, and the juice yield can be increased.
In some alternative embodiments, the cross-section of the curved blade bar 400 may also be triangular, i.e., the curved blade bar 400 includes only an inner surface 412, a first side 413, and a second side 414, with the first side 413 interfacing with the second side 414. The inner surface 412 and the first side surface 413 are acute angles, the inner surface 412 and the second side surface 414 are acute angles, and the first side surface 413 and the second side surface 414 are obtuse angles. The first side 413 and the second side 414 are at an obtuse angle, and the blade can scrape the fruit flesh, but the fruit peel is not easily damaged due to the large angle and the direction of the cutting edge perpendicular to the cutting feed direction.
When the lower end of the main shaft 200 and the curved blade 400 are located inside the fruit, the curved blade 400 scrapes the pulp located on its sweeping path when the main shaft 200 rotates. The main shaft 200 is oscillated with respect to the fruit space while the main shaft 200 is rotated, and the inside of the fruit is inserted to different depths so that the curved blade bar 400 contacts the pulp as much as possible, thereby gradually scraping the pulp from the center of the fruit to between the peels. The pulp scraped by the curved blade 400 and the juice squeezed therefrom remain inside the fruit without an additional container. The main shaft 200 is a hollow shaft, and is equivalent to a suction pipe, and can directly suck the juice from one end of the outlet section 210 of the main shaft 200. By using the fruit juice preparation device provided by the embodiment, most of the fruit pulp can be exposed without cutting the orange, and the fruit pulp can be processed in the orange, so that the fruit juice can not flow greatly, the pollution of the fruit juice to a cutter, a chopping board and the hand of an operator is reduced, and the cleaning work and the using amount of cleaning water can be obviously reduced.
To improve the safety of the juice making device, the juice making device may further comprise a guard mechanism 500. The protection mechanism 500 includes a protection member 510, the protection member 510 has a disc shape, the disc is provided with a central hole 511, a relief groove 512 communicated with the central hole 511, and an outer circumferential surface 513, a cylindrical structure with equal inner diameter is surrounded around the central hole 511, and the cylindrical structure has a larger contact area with the spindle 200, so that a better guiding effect can be achieved, and the protection member 510 can slide along the spindle 200 more smoothly. The relief groove 512 communicates with the central hole 511 and penetrates the cylindrical structure surrounding the central hole 511 in the axial direction. The avoiding groove 512 is an elongated groove with a width slightly larger than that of the curved blade bar 400 and is used for the curved blade bar 400 to pass through; in some alternative embodiments, the relief groove 512 may also be a hollow structure with a sector shape, a circular shape, or other shapes. The central hole 511 and the cylindrical structure are mounting portions of the shield member 510, and the outer circumferential surface 513 is a shield portion. The guard member 510 is sleeved to the main shaft 200 through the center hole 511. The guard member 510 is axially movable along the spindle 200 when subjected to a force acting axially along the spindle 200 to move the portion of the bent blade strip 400 between its ends into and out of the relief groove 512 of the guard member 510. The protective member 510 in this embodiment cannot completely surround the curved blade section 400 in the axial direction, and the outer circumferential surface 513 can surround the highest portion of the curved blade section 400 protruding from the spindle 200. Generally, the highest point of the curved blade strip 400 relative to the circumferential surface of the main shaft 200 is more likely to contact objects around the main shaft 200, and the linear velocity of the highest point is the highest when the main shaft 200 rotates, so that the risk of accidental damage to the blade body can be greatly reduced by surrounding the blade body from the circumferential direction through the outer circumferential surface 513 of the protective member 510. Of course, the guard member 510 may be a cylindrical structure capable of completely circumferentially surrounding the curved blade bar 400, which is more secure but may significantly increase the length requirement of the spindle 200.
When the juice preparing device is not used, the guard member 510 is held at the end of the main shaft 200, and the curved blade bar 400 is located in the relief groove 512 of the guard member 510. Since the outer circumferential surface 513 of the guard member 510 has a diameter larger than that of the curved blade bar 400 and a smooth surface surrounding the curved blade bar 400, it is possible to prevent the curved blade bar 400 from causing physical damage to the human body when the juice preparing apparatus is erroneously started.
When the fruit juice preparing device is used, a hole with the diameter smaller than that of the protective component 510 is firstly formed on the fruit, and the bent blade 400 is inserted into the fruit through the hole of the fruit. During the process of the curved blade bar 400 entering the inside of the fruit, the protective member 510 blocked by the opening part peel can slide along the main shaft 200 to approach the mounting base body 100 and leave the area where the curved blade bar 400 is located, i.e. the curved blade bar 400 is separated from the abdicating groove 512 of the protective member 510 and stays at the extension 230 of the main shaft 200. The guard member 510 does not rotate with the main shaft 200 while the curved blade 400 rotates with the main shaft 200, and remains outside the fruit at all times. The arrangement enables dangerous parts in the revolving part to be positioned inside the fruit, and ensures the safety of operators.
In this embodiment, the guard member 510 is a planar disk having a smaller axial dimension. In use, the protective member 510 cannot enter the inside of the fruit after the curved blade bar 400 is inserted into the fruit, and as the curved blade bar 400 goes deep into the fruit, the protective member 510 moves on the main shaft 200 and approaches the mounting base 100 under the pushing force of the fruit, a part of the extension 230 enters the inside of the fruit, another part stays outside the fruit, and the protective member 510 also keeps the part of the extension 230 staying outside the fruit. If the guard member 510 is cylindrical in shape, and its axial dimension is large, a large length of the extension 230 is required to accommodate the guard member 510. The protection member 510 is a hollow-out planar disk structure, which can not only realize the protection function, but also reduce the axial space of the extension section 230, so that the main shaft 200 has a shorter length and the juice making device has a smaller size.
The guard mechanism 500 may be configured to be held at the position of the bent blade bar 400 by the gravity of the guard member 510, may be manually slid by a user to the position of the bent blade bar 400, or may be configured to hold the guard member 510 at the bent blade bar 400 by a return mechanism so that the guard member 510 can be automatically returned to the position of the bent blade bar 400 in the absence of an external force (e.g., when the bent blade bar 400 is withdrawn from a fruit). The reset mechanism may be a spring sleeved on the main shaft 200, one end of the spring is connected or abutted against the protection member 510, and the other end of the spring is connected with the mounting base 100. In this embodiment, the guard member 510 is provided to be linked with the safety switch mechanism 600 so as to be held at the position of the curved blade bar 400. The following description will be made in conjunction with a specific structure of the safety switch mechanism 600.
The safety switch mechanism 600 includes a safety switch 610, a trigger member 620 and a return spring 630. The safety switch 610 is a normally open switch and is connected in series to a rotation driving circuit (not shown), when the safety switch 610 is in an off state, the motor 310 cannot be started, and the main shaft 200 cannot drive the bending blade 400 to rotate.
The mounting base 100 is provided with a hole 130, and the hole 130 is a blind hole. The side wall of the hole 130 is provided with a hole for passing a button of the safety switch 610. The safety switch 610 is disposed in the mounting base 100, and the button of the safety switch 610 may extend from the hole on the sidewall of the hole 130 to the hole 130. The return spring 630 is disposed inside the hole 130, one end of which abuts against the bottom of the hole 130 and the other end of which is used for receiving an external force, and the return spring 630 is used for returning the trigger member 620. The trigger member 620 is coaxial with the bore 130 and is free to access the bore 130.
The triggering member 620 is used to trigger or turn off the safety switch 610, and the triggering member 620 can activate or turn off the safety switch 610 when it is moved or deformed in a direction parallel to the main shaft 200. The trigger member 620 may be triggered by an external force, for example, the trigger member 620 may be configured to contact the outer surface of the fruit when the bending blade 400 enters the fruit to a certain depth, and the trigger member 620 is deformed or moved by the pressure of the outer surface of the fruit to apply a force to the safety switch 610 when the bending blade 400 further enters the interior of the fruit. In this embodiment, the triggering member 620 is a triggering rod, one end of which is connected to the shielding member 510 and the other end of which is located in the hole 130. The trigger member 620 is capable of moving with the guard member 510 and into or out of the bore 130 as the guard member 510 moves axially along the main shaft 200, thereby applying a force or withdrawing a force to the button of the safety switch 610 to effect activation or deactivation of the safety switch 610. The end face of the trigger rod, which can enter the hole 130, is an inclined plane (end face not perpendicular to the rod axis), and when the trigger rod enters the hole 130 along the axis of the hole 130, the inclined plane can drive the button of the safety switch 610 to move along the direction perpendicular to the axis of the hole 130, which is equivalent to pressing the button, so that the safety switch 610 is switched on; when the trigger lever moves outward along the axis of the bore 130, the safety switch 610 opens when it comes out of contact with the button of the safety switch 610, thus breaking the circuit of the motor 310. The hole 130 in the mounting base 100, in addition to receiving the return spring 630 and the trigger lever, also provides a guide for the movement of the trigger lever.
The trigger member 620 is coupled to the guard member 510, and the reset of the trigger member 620 also drives the guard member 510 to reset, so the return spring 630 and the trigger member 620 are also the reset mechanism (return spring and reset lever) of the guard mechanism 500. In addition, the triggering member 620 is connected to the protection member 510, and both of them can form a rigid body, and the cooperation between the triggering rod and the hole 130 and the cooperation between the protection member 510 and the main shaft 200 can generate a guiding function for the rigid body, so that both of them can slide more smoothly.
Of course, the reset mechanism is not limited to the structure described in the foregoing description, and the reset lever (the trigger member 620) does not necessarily need to be guided by the hole 130 (the guide hole) of the mounting base 100, as long as the reset lever can be constrained on the mounting base 100 and can slide along the axial direction of the main shaft 200, for example, two or more coaxial rings with a certain distance can be provided on the surface of the mounting base 100, and the reset lever can move in the ring hole.
In the above-described embodiment, the reset rod is coupled to the shielding member 510 by one end thereof to realize the linkage with the shielding member, but the coupling between the reset rod and the shielding member 510 is not necessary, for example, the reset rod and the shielding member 510 may be in abutting contact, the shielding member 510 may also drive the reset rod to move when approaching the mounting base 100 along the main shaft 200, and the reset rod may also drive the shielding member 510 to reset when moving towards the end of the main shaft 200 under the action of the reset spring 630.
In some alternative embodiments, the return spring 630 may also be disposed not in the bore 130, such as may be disposed on the spindle 200. The return spring 630 may drive the guard member 510 to return, and since the guard member 510 is linked to the trigger member 620, the trigger member 620 may also be driven to return when the guard member 510 returns.
In some alternative embodiments, the triggering member 620 may be replaced by a spring, one end of which is connected to the guard member 510, and the other end of which directly or indirectly acts on a triggering button of the safety switch (correspondingly, the pressing or bouncing direction of the button of the safety switch is set to be axial along the main shaft 200), and the button of the safety switch can be pressed down to trigger the switch when the spring is compressed to a predetermined length. The spring may be fitted around the outer circumferential surface of the main shaft 200, or may be disposed parallel to the main shaft 200 at one side of the main shaft 200.
In this embodiment, the guard mechanism 500 is configured to be capable of linking with the safety switch mechanism 600, that is, when a part of the members in the guard mechanism 500 moves along the axial direction of the main shaft 200, the part of the members in the safety switch mechanism 600 can be driven to move, and the two are configured to link to simplify the structure of the juice preparing device, but not to fulfill the necessary condition for preparing juice. In other alternative embodiments, the guard mechanism 500 and the safety switch mechanism 600 may also be individually actuated.
The juice producing device in this embodiment further comprises a battery (not shown) for supplying power to the motor 310. In some alternative embodiments, the juice preparing device is not provided with a battery, but is provided with a power supply interface instead of the battery, and the motor 310 can be powered by the connection of an external power supply and the power supply interface. The size and mass of the juice making device without batteries can be significantly reduced.
The complete operation of the juice preparation device is described below.
A hole of a diameter corresponding to the curved blade 400 is made in the outer surface of a fruit such as an orange, or a part of the peel of the fruit is cut off, leaving a part of the flesh exposed or nearly exposed. The operator holds the mounting base 100 and inserts the extension 230 of the main shaft 200, the tool mounting section 240, and the curved blade 400 into the interior of the fruit. In this process, the guard member 510 cannot enter the interior of the fruit, and therefore the guard member 510 slides along the main shaft 200 and disengages from the curved blade bar 400. At the same time, the guard member 510 drives the trigger member 620 to move in a direction parallel to the main shaft 200, when the curved blade 400 is completely inserted into the main shaft, the slope of the top end of the trigger member 620 triggers the safety switch 610, and at this time, the operator turns on the main switch, the motor 310 drives the main shaft 200 to rotate, and the curved blade 400 starts to scrape the pulp around the curved blade. The operator can change the depth and angle of the main shaft 200 into the interior of the fruit, thereby enabling the curved blade bar 400 to scrape most of the pulp inside the fruit.
After the pulp processing is completed, the operator closes the main switch and sucks the juice from the end of the outlet section 210 of the main shaft 200.
After the operator finishes eating the food, the main shaft 200 is withdrawn from the fruit, and the trigger member 620 gradually protrudes from the hole 130 by the return spring 630, and drives the guard member 510 to slide toward the position of the curved blade bar 400. When the triggering member 620 is finally reset, the slope of one end of the triggering member 620 is separated from the contact of the safety switch 610 to turn off the safety switch 610; the guard member 510 reaches the position of the curved blade bar 400 and envelops the curved blade bar 400. When the curved blade 400 is pulled out of the fruit, if the operator accidentally triggers the main switch, the motor 310 will not be started because the safety switch 610 is in the off state. Moreover, even if the circuit is connected due to a failure, since one end of the trigger 620 is still located in the hole 130 of the mounting base 100 and the other end is fixed to the protective member 510, the rotation of the spindle 200 is hindered, the bent blade strip 400 is prevented from rotating to cause a danger, and the safety factor is further increased.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a guard mechanism according to another embodiment of the present invention, and the structure of the curved blade bar 400 is not shown in the figure in order to show the structure of the guard mechanism more clearly. The protection mechanism comprises a protection component 510 and a reset mechanism, the reset mechanism comprises two movable rod groups 520, each movable rod group 520 comprises a first rod 521, a second rod 522 and an elastic piece 523, the first rods 521 are hinged to the installation base body 100, one end of each second rod 522 is hinged to the first rods 521, the other end of each second rod 522 is hinged to the protection component 510, the elastic pieces 523 are arranged between the first rods 521 and the second rods 522, and the elastic pieces 523 can be tensioned when the opening angle between the first rods 521 and the second rods 522 is reduced. The initial angle between the first 521 and second 522 rods is less than 180 degrees.
The elastic member 523 is a torsion spring in this embodiment, and is connected to the hinge of the first lever 521 and the second lever 522. When the protection member 510 approaches the mounting base 100 along the spindle 200, the protection member 510 drives the movable rod group 520 to move, so that the included angle between the first rod 521 and the second rod 522 is reduced, the stress in the torsion spring is increased, and a reset force is generated, when the force for driving the protection member 510 to approach the mounting base 100 disappears, the elastic member 523 can drive the first rod 521 to open relative to the second rod 522, and the movable rod group 520 can drive the protection member 510 to reset to the position of the curved blade bar 400.
In other embodiments, the movable rod set 520 and the safety switch mechanism 600 may be linked, for example, a lever or a cam may be disposed on the first rod 521, such that the lever or the cam can press a button of the safety switch 610 when the first rod 521 rotates to a certain angle.
In some alternative embodiments, the elastic member 523 may also be a tension spring or a compression spring. The spring can be extended or compressed to accumulate energy when the angle between the first 521 and second 522 levers is changed.
In other alternative embodiments, the elastic member 523 may also be an elastic band, which can be stretched to store energy when the angle between the first rod 521 and the second rod 522 is reduced.
Fig. 6 is a partial schematic view of a juice producing device according to another embodiment of the present invention, fig. 7 is a sectional view of the juice producing device of fig. 6, and fig. 8 is a schematic view of the juice producing device of fig. 6 with a tray hidden.
The juice preparing device shown in fig. 6 to 8 has substantially the same structure as the juice preparing device described in the previous embodiment except for the structure of the safety switch mechanism and the guard mechanism, and will be described in detail below with reference to the accompanying drawings.
In this embodiment, the juice preparation device includes the following structure: the mounting base body 100, the main shaft 200, the rotary driving, the bending cutter bar 400, the protection mechanism 500a and the safety switch mechanism 600 a. The connection relationship among the main shaft 200, the rotary driving and bending blade 400 and the connection relationship between them and the mounting base 100 are the same as those of the juice preparing apparatus shown in fig. 2, and the detailed structure can be referred to the description of the previous embodiment.
In this embodiment, the guard mechanism 500a includes a guard member 510a and a spring 630a, and the safety switch mechanism 600a includes a safety switch 610a and a trigger member 620 a.
The main body of the protection member 510a is a dome-shaped (umbrella-shaped) disk, the disk is provided with a center hole 511a, a relief groove 512a communicating with the center hole 511a, and an outer circumferential surface 513a, a cylindrical structure with a uniform inner diameter is surrounded around the center hole 511a, and a larger shaft hole contact area is provided between the cylindrical structure and the main shaft 200. The relief groove 512a communicates with the center hole 511a and does not penetrate the cylindrical structure surrounding the center hole 511a in the axial direction. The central hole 511a and the barrel structure are installation parts of the shielding member 510a, and the solid structure between the outer circumferential surface 513a and the receding groove 512a is a shielding part. The shield member 510a is fitted to the main shaft 200 through the center hole 511 a. The guard member 510a is axially movable along the spindle 200 when subjected to a force acting in the axial direction of the spindle 200 to move the body portion of the bent blade bar 400 between the ends thereof into and out of the relief groove 512a of the guard member 510 a. Since the relief groove 512a does not penetrate the cylindrical structure surrounding the central hole 511a in the axial direction, the shield member 510a is prevented from falling off the main shaft 200 by the cylindrical structure when moving toward the end of the main shaft 200.
The spring 630a is fitted over the main shaft 200 between the shield member 510a and the mounting base 100, and the shield member 510a compresses the spring 630a when moving along the main shaft 200 to approach the mounting base 100.
The safety switch 610a is provided on the mounting base 100 with the push and pop directions of the switch knob parallel to the axial direction of the spindle 200.
The trigger member 620a includes a sleeve portion and a pressing portion, the pressing portion protrudes from an outer circumferential surface of the sleeve portion along a radial direction of the sleeve portion, and a recess portion for engaging with a button of the safety switch 610a is further provided on the pressing portion. The sleeve portion has a sleeve inner diameter equal to the diameter of the spindle 200, and the trigger member 620a is fitted over the spindle 200 through the sleeve portion and located between the spring 630a and the mounting base 100. The pressing portion of the triggering member 620a is inserted into the button of the safety switch 610a through the recess, and the triggering member 620a is prevented from rotating out of contact with the safety switch 610 a. When the trigger member 620a moves closer to the mounting base 100 along the spindle 200, the pressing portion thereof can trigger the safety switch 610 a.
The shield member 510a is capable of compressing the spring 630a as it moves along the spindle 200 toward the mounting base 100, the spring 630a acting on the trigger member 620a, the spring 630a having sufficient stress to drive the trigger member 620a to depress the button of the safety switch 610a when the shield member 510a moves to a predetermined position (which may be when the shield member 510a is fully disengaged from the curved blade bar 400), thereby causing the safety switch 610a to close.
In some alternative embodiments, the tab portion of the trigger member 620a may also be a flange that surrounds the sleeve portion so that the guard member 510a does not come out of contact with the safety switch 610a even if it is rotated. In other alternative embodiments, the spring 630a may be disposed on one side of the main shaft 200 (not sleeved on the main shaft 200), and the spring 630a may be a button having one end directly connected to the disc of the shielding member 510a and the other end capable of driving the pressing piece of the triggering member 620a or directly driving the safety switch 610 a.
In some embodiments, it is also possible not to provide the triggering member 620a, but to enable the spring 630a to directly contact the safety switch 610a by placing the safety switch 610a in a suitable position (e.g., closer to the main shaft 200), so that the spring 630a can directly trigger the safety switch 610 a.
The embodiment of the invention also discloses a protection component, and the specific structure thereof refers to the protection component 510, the protection component 510a and the corresponding embodiment in fig. 1 to fig. 6. In order to improve the safety of the juice making device, the juice making device may further include a protective member 510, the main body of the protective member 510 is a disc, the disc is provided with a central hole 511, a relief groove 512 communicated with the central hole 511 and an outer circumferential surface 513, a cylinder structure with a uniform inner diameter is surrounded around the central hole 511, the cylinder structure and the main shaft 200 have a larger contact area, so that a better guiding effect can be achieved, and the protective member 510 can slide along the main shaft 200 more smoothly. The relief groove 512 communicates with the central hole 511 and penetrates the cylindrical structure surrounding the central hole 511 in the axial direction. The avoiding groove 512 is an elongated groove with a width slightly larger than that of the curved blade bar 400 and is used for the curved blade bar 400 to pass through; in some alternative embodiments, the relief groove 512 may also be a hollow structure with a sector shape, a circular shape, or other shapes. The central hole 511 and the cylindrical structure are mounting portions of the shield member 510, and the outer circumferential surface 513 is a shield portion. The guard member 510 is sleeved to the main shaft 200 through the center hole 511. The guard member 510 is axially movable along the spindle 200 when subjected to a force acting axially along the spindle 200 to move the portion of the bent blade strip 400 between its ends into and out of the relief groove 512 of the guard member 510. The protective member 510 in this embodiment cannot completely surround the curved blade section 400 in the axial direction, and the outer circumferential surface 513 can surround the highest portion of the curved blade section 400 protruding from the spindle 200. Generally, the highest point of the curved blade strip 400 relative to the circumferential surface of the main shaft 200 is more likely to contact objects around the main shaft 200, and the linear velocity of the highest point is the highest when the main shaft 200 rotates, so that the risk of accidental damage to the blade body can be greatly reduced by surrounding the blade body from the circumferential direction through the outer circumferential surface 513 of the protective member 510. Of course, the guard member 510 may be a cylindrical structure capable of completely circumferentially surrounding the curved blade bar 400, which is more secure but may significantly increase the length requirement of the spindle 200.
When the juice preparing device is not used, the guard member 510 is held at the end of the main shaft 200, and the curved blade bar 400 is located in the relief groove 512 of the guard member 510. Since the 3 outer circumferential surface 513 of the guard member 510 has a diameter larger than that of the curved blade bar 400 and a smooth surface surrounding the curved blade bar 400, it is possible to prevent the curved blade bar 400 from causing physical damage to the human body when the juice preparing apparatus is erroneously started.
When the fruit juice preparing device is used, a hole with the diameter smaller than that of the protective component 510 is firstly formed on the fruit, and the bent blade 400 is inserted into the fruit through the hole of the fruit. During the process of the curved blade bar 400 entering the inside of the fruit, the protective member 510 blocked by the opening part peel can slide along the main shaft 200 to approach the mounting base body 100 and leave the area where the curved blade bar 400 is located, i.e. the curved blade bar 400 is separated from the abdicating groove 512 of the protective member 510 and stays at the extension 230 of the main shaft 200. The guard member 510 does not rotate with the main shaft 200 while the curved blade 400 rotates with the main shaft 200, and remains outside the fruit at all times. The arrangement enables dangerous parts in the revolving part to be positioned inside the fruit, and ensures the safety of operators.
In this embodiment, the guard member 510 is a planar disk having a smaller axial dimension. In use, the protective member 510 cannot enter the inside of the fruit after the curved blade bar 400 is inserted into the fruit, and as the curved blade bar 400 goes deep into the fruit, the protective member 510 moves on the main shaft 200 and approaches the mounting base 100 under the pushing force of the fruit, a part of the extension 230 enters the inside of the fruit, another part stays outside the fruit, and the protective member 510 also keeps the part of the extension 230 staying outside the fruit. If the guard member 510 is cylindrical in shape, and its axial dimension is large, a large length of the extension 230 is required to accommodate the guard member 510. The protection member 510 is a hollow-out planar disk structure, which can not only realize the protection function, but also reduce the axial space of the extension section 230, so that the main shaft 200 has a shorter length and the juice making device has a smaller size.
The guard mechanism 500 may be configured to be held at the position of the bent blade bar 400 by the gravity of the guard member 510, may be manually slid by a user to the position of the bent blade bar 400, or may be configured to hold the guard member 510 at the bent blade bar 400 by a return mechanism so that the guard member 510 can be automatically returned to the position of the bent blade bar 400 in the absence of an external force (e.g., when the bent blade bar 400 is withdrawn from a fruit). The reset mechanism may be a spring sleeved on the main shaft 200, one end of the spring is connected or abutted against the protection member 510, and the other end of the spring is connected with the mounting base 100.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
