Description

Technical Field

[0001] This application relates to the field of kitchenware, and more particularly to a locking structure and a mixer including the structure. Background Technology

[0002] Blenders are now commonly used in people's daily lives to make it convenient to break up ingredients or mix different ingredients evenly during cooking.

[0003] The mixers in the related technology typically include a base and a mixing mechanism mounted on the base. The base has a mixing container for holding food. One end of the mixing mechanism is hinged to the base, and the plane of rotation of the mixing mechanism is vertical. The other end of the mixing mechanism has a stirring rod for stirring. The stirring rod is vertically inserted into the mixing container. The stirring rod rotates to stir the food in the mixing container. After stirring is completed, the mixing mechanism can be manually rotated to flip it up, thereby removing the stirring rod from the mixing container.

[0004] Regarding the aforementioned technologies, the inventors believe that during the rotation of the stirring rod, the main body of the stirring mechanism is prone to shaking, which affects the stirring quality and poses a safety hazard. Summary of the Invention

[0005] To minimize the shaking of the stirring mechanism during the rotation of the stirring rod, this application provides a locking structure and a mixer including the structure.

[0006] Firstly, this application provides a locking structure:

[0007] A locking structure includes a first body and a second body;

[0008] The rotating arm has one end fixedly mounted on the second main body and the other end hinged to the first main body;

[0009] A fastener is fixedly mounted on the first main body, and the fastener is provided with a slot.

[0010] A locking pin is slidably disposed on the second body, can be inserted into the slot, and the locking pin is adapted to the slot;

[0011] The drive switch is rotatably mounted on the second main body;

[0012] A transmission component is movably mounted on the second main body. Both ends of the transmission component are connected to the drive switch and the locking pin, respectively. The drive switch is used to drive the transmission component to move, and the transmission component is used to drive the locking pin to move.

[0013] By adopting the above technical solution, the second body is rotatably connected to the first body via a rotating arm. A toggle switch rotates the body, and a transmission component pushes the locking pin into or out of the slot. When the locking pin is inserted into the slot, its side fits against the slot wall, restricting the relative rotation between the first and second bodies. When the locking pin is withdrawn from the slot, the restriction on relative rotation between the first and second bodies is removed, thus achieving both locking and unlocking of rotation between the first and second bodies.

[0014] Optionally, a mounting base is integrally provided on the second main body, and a limiting hole is provided on the mounting base. One end of the limiting hole is open and faces the slot. A guide elongated hole is provided on the side of the mounting base. The guide elongated hole is connected to the limiting hole. The straight line of the length direction of the guide elongated hole is parallel to the straight line of the opening direction of the limiting hole. The guide elongated hole is provided through the hole wall on the side away from the slot.

[0015] The locking pin includes a pin body and a push rod disposed on the pin body. The push rod is perpendicular to the pin body. The pin body passes through the limiting hole and is slidably disposed within the limiting hole. The push rod passes through the guide elongated hole and slides along the length direction of the guide elongated hole. The transmission member is connected to the push rod.

[0016] By adopting the above technical solution, the wall of the limiting hole plays the role of positioning the locking pin, so that when the first body and the second body need to be locked, the locking pin can be easily and accurately inserted into the insertion hole; through the cooperation of the push rod and the guide hole, on the one hand, the transmission component is connected to the push rod to push the rod body to move closer to or away from the slot, on the other hand, the push rod can restrict the locking pin from sliding out of the limiting hole in the direction closer to the slot, and restrict the locking pin from rotating in the limiting groove, which greatly improves the stability of the locking pin during movement.

[0017] Optionally, an abutment is fixedly provided on the second main body, and the locking pin is disposed between the abutment and the slot. An elastic element is provided at one end of the abutment near the locking pin. The two ends of the elastic element are respectively connected to the abutment and the locking pin. The elastic element has elastic potential energy to drive the locking pin to move closer to the slot.

[0018] By adopting the above technical solution, when the locking pin is inserted into the slot, the presence of the elastic element increases the force required to actuate the drive switch, making it less likely that the locking pin will be accidentally pulled out of the slot due to accidental activation of the drive switch. On the other hand, after the drive switch is actuated to pull the locking pin out of the slot and the first and second bodies rotate and separate, releasing the drive switch causes the elastic element to automatically reset and pop out the locking pin. During the process of pressing the first and second bodies together, the popped-out locking pin abuts against the fixing member and slides towards the slot. The locking pin retracts and gradually compresses the elastic element, which stores elastic potential energy. When the locking pin moves to the position of the slot, the elastic element releases the elastic potential energy and automatically pushes the locking pin into the slot. There is no need to manually operate the drive switch, making the operation more convenient.

[0019] Optionally, the abutment member is provided with a receiving groove, the elastic member is disposed in the receiving groove, and the locking pin can slide within the receiving groove.

[0020] By adopting the above technical solution, on the one hand, the elastic element set in the receiving groove is more stable during the compression process; on the other hand, when the locking pin retracts, the end of the locking pin near the abutment can be inserted into the receiving groove, and the groove wall of the receiving groove restricts the locking pin from lateral shaking, further improving the stability of the locking pin during movement.

[0021] Secondly, this application provides a mixer including the locking structure.

[0022] A mixer includes the aforementioned locking structure, a stirring container disposed on a first main body, a stirring rod rotatably disposed on a second main body, a drive mechanism disposed on the second main body, and a control circuit module; the first main body has an installation space, the stirring container is installed in the installation space, and the stirring container is disposed between the first main body and the second main body; one end of the stirring rod is connected to the drive mechanism, and the other end of the stirring rod faces the interior space of the stirring container; the control circuit module is used to control the working state of the drive mechanism, and the drive mechanism is used to drive the stirring rod to rotate around its own axis.

[0023] By adopting the above technical solution, when the stirring rod is inserted into the mixing container, the drive mechanism is activated, and the stirring rod rotates to stir the food in the mixing container. During the stirring process, the locking pin on the second body is inserted into the slot on the fixing member fixed on the first body, which restricts the tendency of the first body and the second body to rotate relative to each other, thereby improving the stability and safety of the mixer during operation. After the stirring is completed, the drive switch is turned on, the locking pin is pulled out of the slot, the restriction on the relative rotation between the first body and the second body is removed, and the stirring rod can be pulled out of the mixing container by rotating the second body, thus making it convenient to take out the stirred food in the mixing container.

[0024] Optionally, the driving mechanism includes a driving component and a transmission component. The transmission component includes a transmission shaft with an internal gear and a transmission disk. The driving mechanism is fixedly mounted on the second main body. One end of the transmission shaft is connected to the output end of the driving component, and the other end of the transmission shaft is fixedly connected to the axis of the transmission disk. The driving component is used to drive the transmission shaft to rotate around its axis. The end of the stirring rod away from the stirring container is rotatably mounted on the transmission disk, and the connection point between the stirring rod and the transmission disk is adjacent to the transmission shaft.

[0025] The internal gear is fixedly mounted on the second main body, the transmission shaft passes through the internal gear, and the internal gear is coaxially mounted with the transmission disk; a drive gear is coaxially fixedly mounted on one end of the stirring rod near the internal gear, and the drive gear meshes with the internal gear.

[0026] By adopting the above technical solution, the drive component drives the transmission rod to rotate the transmission disk. The stirring rod set on the transmission disk can rotate eccentrically around the transmission shaft with the rotating transmission disk. When the stirring rod moves eccentrically, the drive gear fixed at one end of the stirring rod rotates relative to the internal gear, so that the stirring rod can rotate around its own axis while rotating eccentrically. Compared with the stirring rod rotating tightly around its own axis, the stirring effect and stirring quality are better.

[0027] Optionally, a first bevel gear is coaxially fixed at the end of the drive shaft away from the drive disc, and a second bevel gear is fixedly fixed at the output end of the drive assembly. The rotation plane of the first bevel gear is perpendicular to the rotation plane of the second bevel gear, and the first bevel gear and the second bevel gear mesh with each other.

[0028] By adopting the above technical solution, the transmission direction of the drive component is changed, so that the output end of the drive component can be set in a direction perpendicular to the stirring rod, thereby reducing the overall height of the mixer as much as possible. On the one hand, this saves space, and on the other hand, it lowers the center of gravity, making the mixer more stable during operation.

[0029] Optionally, the drive assembly includes a drive element, an output shaft, and a planetary gear set, wherein the planetary gear set is connected between the output end of the drive element and one end of the output shaft, and the second bevel gear is disposed at the other end of the output shaft.

[0030] By adopting the above technical solution, the planetary gear set serves two purposes: firstly, it reduces the output shaft speed; secondly, the planetary gear transmission makes the output shaft rotation more stable, thereby further improving the stability of the mixer during operation.

[0031] Optionally, the control circuit module includes a main control module and a normally open elastic switch. The normally open elastic switch is connected between the main control module and the drive mechanism, and the normally open elastic switch is fixedly mounted on the first body. When the stirring rod rotates into the stirring container, the rotating arm presses the spring of the normally open elastic switch to close the normally open elastic switch.

[0032] By adopting the above technical solution, in actual use, it is easy for accidental touches of the drive switch or children's curiosity to rotate the second main body during the operation of the mixer, pulling the rotating stir bar out of the mixing container. The normally open elastic switch connected between the main control module and the drive mechanism can keep the circuit connected when the stirring rod is working in the mixing container. When the second main body rotates relative to the first main body, the power supply of the drive mechanism is cut off, so that the rotating stirring rod stops rotating in time, minimizing the risk of injury to personnel from the rotating stirring rod.

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] This application discloses a mixer, as shown in the embodiments below. Figure 1 and Figure 2 The mixer includes a first body 1 and a second body 2 disposed above the first body 1. Both the first body 1 and the second body 2 are hollow shells. The first body 1 serves as a base for overall support. A rotating arm 11 is hinged to one end inside the first body 1. The end of the rotating arm 11 near the second body 2 is fixed to the first body 1 by bolts. The rotation plane of the rotating arm 11 is vertical, thereby hinged the second body 2 to the first body 1. An installation space 12 is provided at the end of the first body 1 away from the rotating arm 11. The mixer also includes a mixing container 3 that can be rotatably engaged with the first body 1, and a mixing container disposed inside the first body 1. The control circuit module 4, the drive mechanism 5 disposed within the second main body 2, and the stirring rod 6 rotatably disposed on the second main body 2, with the stirring container 3 disposed within the installation space 12; the end of the stirring rod 6 away from the second main body 2 extends into the stirring container 3, and when the stirring rod 6 is vertically disposed within the stirring container 3, the second main body 2 is in an initial state relative to the first main body 1; the drive mechanism 5 is used to drive the stirring rod 6 to rotate, and the control circuit module 4 is used to control the working state of the drive mechanism 5; a locking structure 7 is disposed between the first main body 1 and the second main body 2 near the rotating arm 11, and the locking structure 7 is used to restrict the rotation of the second main body 2 relative to the first main body 1.

[0042] Reference Figure 2 and Figure 3The locking structure 7 includes a fixing member 71 fixed inside the first body 1 by bolts, a locking pin 72 slidably disposed on the second body 2, a drive switch 73 hinged to the second body 2, and a transmission member 74. The locking pin 72 slides vertically, and one end of the locking pin 72 near the first body 1 extends through the shell wall of the second body 2 to the outside of the second body 2. The fixing member 71 is disposed at one end of the first body 1 near the locking pin 72, and a slot 711 is opened on the side surface of the fixing member 71 near the locking pin 72. When the second body 2 is in the initial position, the locking pin 72 can be inserted into one of the slots 711. One end of the drive switch 73 extends to the outside of the second body 2. The transmission member 74 is disposed between the drive switch 73 and the locking pin 72, and both ends of the transmission member 74 are respectively connected to the drive switch 73 and the locking pin 72. The drive switch 73 is used to drive the transmission member 74 to move, and the transmission member 74 is used to drive the locking pin 72 to move. When the second body 2 is in the initial position, the locking pin 72 is inserted into the slot 711. The first body 1 and the second body 2 are connected by the locking pin 72. The second body 2 is less likely to rotate relative to the first body 1, which improves stability. When the drive switch 73 is turned on, the locking pin 72 is driven upward by the transmission component 74. The locking pin 72 is pulled out from the slot 711, which removes the restriction on the rotation of the second body 2.

[0043] Reference Figure 2 and Figure 3 The drive switch 73 includes a hinge rod 731 hinged to the second body 2, a switch plate 732 integrally disposed on the side of the hinge rod 731, and an actuating member 733 disposed on the side of the hinge rod 731 away from the switch plate 732. The hinge rod 731 is horizontally disposed and rotates about its own axis. The end of the switch plate 732 away from the hinge rod 731 extends to the outside of the second body 2. The actuating member 733 includes a connecting part 7331 connected to one end of the hinge rod 731 and an actuating part 7332 integrally connected to the other end of the connecting part 7331. 32 is horizontally positioned and its length direction is parallel to the hinge rod 731; the transmission component 74 includes a connecting rod 741 hinged to the second body 2, a first transmission rod 742 integrally disposed on the side of the connecting rod 741 near the drive switch 73, and two second transmission rods 743 integrally disposed on the side of the connecting rod 741 near the locking pin 72. The connecting rod 741 is parallel to the hinge rod 731 and rotates around its own axis; the end of the first transmission rod 742 away from the connecting rod 741 is provided with a U-shaped notch, and the actuating part 7332 is inserted into the U-shaped notch.

[0044] Reference Figure 3 and Figure 4A mounting base 21 is integrally formed on the inner wall of the second main body 2. A limiting hole 211 is vertically formed on the mounting base 21, and one end of the limiting hole 211 is open and faces the slot 711. Two guide holes 212 with opposite openings are vertically formed on the side of the mounting base 21. The guide holes 212 and the limiting hole 211 are interconnected. The straight line of the length direction of the guide holes 212 is parallel to the straight line of the opening direction of the limiting hole 211. The side wall of the guide holes 212 away from the slot 711 is through the hole. The locking pin 72 includes a pin body 721 and a locking pin 722. The two push rods 722 on the side of the mounting base 21 have a circular cross-section for the pin body 721. The push rods 722 are perpendicular to the axis of the pin body 721 and collinear. The two push rods 722 pass through the two limiting holes 211 respectively and slide within the limiting holes 211. The two push rods 722 also pass through the two guide holes 212 respectively and slide vertically along the guide holes 212. The structure of the second transmission rod 743 is the same as that of the first transmission rod 742. The two push rods 722 are respectively inserted into the two U-shaped notches on the two second transmission rods 743. When the switch plate 732 is moved upward, the actuating part 7332 presses down the first transmission rod 742, and the second transmission rod 743 moves upward, pushing the locking pin 72 upward, causing the locking pin 72 to retract. Conversely, the locking pin 72 moves downward, causing the locking pin 72 to extend. The mounting base 21 and the push rods 722 improve the stability of the locking pin 72 during movement.

[0045] Reference Figure 3 and Figure 4An abutment member 22 is bolted to the second body 2, adjacent to the mounting base 21. The abutment member 22 includes a fixing part 221 fixed to the second body 2 and an abutment part 222 integrally disposed above the fixing part 221. The abutment part 222 extends above the mounting base 21. A receiving groove (not shown in the figure due to obstruction) is formed on the side of the abutment part 222 near the mounting base 21. The cross-sectional shape of the receiving groove is circular, and the cross-sectional size of the receiving groove is adapted to the cross-sectional size of the locking pin 72. The groove opening limiting hole 211 of the receiving groove is opposite to it. An elastic element (not shown in the figure due to obstruction) is provided in the receiving groove. The elastic element is a spring, and the two ends of the spring are respectively connected to the bottom of the receiving groove and the locking pin 72. With the end away from the slot 711 pressed against the spring, the spring has elastic potential energy to drive the locking pin 72 toward the slot 711. During the retraction of the locking pin 72, the end of the locking pin 72 that abuts against the elastic element can be inserted into the receiving groove, making the locking pin 72 more stable during movement. The elastic element is designed to prevent the locking pin 72 from being accidentally pulled out of the slot 711 due to accidental contact with the switch dial 732. On the other hand, as the second body 2 gradually rotates to the initial position, the locking pin 72 abuts against the fixing element 71 and gradually moves toward the slot 711. During this process, the elastic element stores elastic potential energy. When the locking pin 72 moves to the slot 711, the elastic element can directly push the locking pin 72 into the slot 711, making the operation more convenient.

[0046] Reference Figure 3 The slot 711 has a circular cross-sectional shape, and its cross-sectional area is the same as that of the locking pin 72. The side surface of the fixing member 71 near the locking pin 72 is arched. There are two slots 711, which are symmetrically located between the highest point and the two lowest points of the arched surface. When the second body 2 gradually rotates to the initial position, the sliding trajectory of the locking pin 72 on the fixing member 71 is on the extension line of the line connecting the two slots 711 on the arched surface. When one of the slots 711 cannot properly fit the locking pin 72 due to wear or the presence of debris that is difficult to clean, the fixing member 71 can be rotated 180 degrees and reinstalled so that the other slot 711 is opposite to the locking pin 72 for normal use, thus avoiding the inconvenience caused by frequent parts replacement.

[0047] Reference Figure 2 and Figure 5The drive mechanism 5 includes a drive assembly 51 and a transmission assembly 52. ​​The transmission assembly 52 includes a drive shaft 521, an internal gear 522, and a transmission disk 523. The drive shaft 521 is vertically arranged, with one end connected to the output end of the drive assembly 51 and the other end coaxially fixedly connected to the transmission disk 523. The drive assembly 51 drives the drive shaft 521 to rotate around its axis. The end of the stirring rod 6 away from the stirring container 3 is rotatably mounted on the transmission disk 523, and the connection point between the stirring rod 6 and the transmission disk 523 is adjacent to the drive shaft 521. The internal gear 522 is fixed inside the second body 2 by bolts, and the drive shaft 521 passes through the internal gear 522. The internal gear 522 is coaxially arranged with the transmission disk 523. One end of the stirring rod 6 near the internal gear 522 extends through the transmission disk 523 and into the interior of the internal gear 522. A drive gear 61 is coaxially fixed to the stirring rod 6 inside the internal gear 522, and the fixed gear meshes with the internal gear 522. The drive assembly 51 drives the transmission rod to rotate the transmission disk 523. The stirring rod 6, which is mounted on the transmission disk 523, can rotate eccentrically around the transmission shaft 521 as the transmission disk 523 rotates. During the eccentric motion of the stirring rod 6, the drive gear 61 fixed at one end of the stirring rod 6 rotates relative to the internal gear 522, so that the stirring rod 6 can rotate around its own axis while rotating eccentrically. Compared with the stirring rod 6 rotating only around its own axis, the stirring effect and stirring quality are better.

[0048] Reference Figure 5 The drive assembly 51 includes a drive component 511, an output shaft 512, and a planetary gear set 513. The drive component 511 is a motor with a built-in cooling fan at the rear. The output shaft 512 is coaxially fixedly connected to the output end of the drive component 511 via the planetary gear set 513. A first bevel gear 5211 is coaxially fixedly mounted on the end of the transmission shaft 521 away from the transmission disk 523, and a second bevel gear 5121 is coaxially fixedly mounted on the output shaft 512. The rotation planes of the first bevel gear 5211 and the second bevel gear 5121 are perpendicular to each other. The first bevel gear 5211 and the second bevel gear 5121 mesh with each other, so that the output shaft 512 of the drive component 511 is perpendicular to the transmission shaft 521, which reduces the overall height of the mixer, lowers the center of gravity, and improves the stability of the mixer during operation. The planetary gear set 513 reduces the speed of the output shaft 512 and makes the output shaft 512 more stable when rotating, thereby further improving the stability of the mixer during operation.

[0049] Reference Figure 2 and Figure 6The control circuit module 4 includes a main control module 41 and a normally open elastic switch 42. The main control module 41 is used to control the working state of the drive component 511. The normally open elastic switch 42 is connected between the main control module 41 and the drive mechanism 5. The normally open elastic switch 42 is fixedly installed on the inner wall of the first body 1 and the spring is opposite to the rotating arm 11. When the second body 2 is in the initial position, the side of the rotating arm 11 close to the normally open elastic switch 42 presses the spring of the normally open elastic switch 42, thereby closing the normally open elastic switch 42 and connecting the circuit between the main control module 41 and the drive component 511, which improves the safety of the mixer during use.

[0050] The implementation principle of a mixer according to an embodiment of this application is as follows: When the second body 2 is in the initial position, the drive mechanism 5 is started, and the stirring rod 6 rotates to stir the food in the stirring container 3. During the stirring process, the locking pin 72 set on the second body 2 is inserted into the slot 711 on the fixing member 71 fixed on the first body 1, which restricts the tendency of the first body 1 and the second body 2 to rotate relative to each other, thereby improving the stability and safety of the mixer during operation. After the stirring is completed, the drive switch 73 is turned on, and the locking pin 72 is pulled out from the slot 711, which removes the restriction on the relative rotation between the first body 1 and the second body 2. The stirring rod 6 can be pulled out from the stirring container 3 by rotating the second body 2, thereby making it convenient to take out the stirred food in the stirring container 3.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
