[0002] Slow juicers evolved from conventional juicers, and their main purpose is still to turn fruit into juice to improve taste and make it easier to drink. However, slow juicers represent a significant leap forward from traditional cup blenders and juicers.

[0003] Traditional juicers mainly consist of a main unit, a juice collection cup, and an internal screw. With continuous technological advancements and rising consumer demands, juicers with integrated feed hoppers have emerged. Their advantage lies in the pre-storage of materials before juicing, making them more convenient to use. However, with this structural optimization, safety requirements have also increased. Ensuring that components do not become loose during operation is a pressing issue that needs to be addressed. Utility Model Content

[0029] See Figure 1-6As shown, the present invention provides a self-locking structure for a juicer, including an installation chamber 1 disposed on a movable cup body, a locking assembly 2 disposed at the lower end of the installation chamber 1, and an elastic push rod assembly 3 slidably disposed in the installation chamber 1 to cooperate with the locking assembly 2, the upper end of the elastic push rod assembly 3 cooperating with the cover body.

[0030] A positioning buckle 4 is integrally formed on the upper end of the main body housing to cooperate with the locking assembly 2; when the cover is closed, the elastic push rod assembly 3 is at the lower limit of its stroke and presses the locking assembly 2 to make the locking assembly 2 engage with the positioning buckle 4; when the cover is open, the elastic push rod assembly 3 is at the upper limit of its stroke and the locking assembly 2 separates from the positioning buckle 4.

[0031] By setting a mutually cooperating elastic push rod assembly and a locking assembly on the moving cup body, and setting a positioning buckle seat on the main body housing that cooperates with the locking assembly, the moving cup body and the main body housing are self-locked by a snap-fit ​​mechanism, which has the advantages of good self-locking stability and simple assembly.

[0032] The flexible top rod assembly works in conjunction with the lid to control the opening and closing of the locking assembly. During use, the lid and locking assembly open and close synchronously. When juicing, closing the lid secures the moving cup to the main housing; when cleaning the moving cup, simply open the lid and locking assembly to unlock it. The entire operation is simple and convenient, achieving two purposes with a single operation.

[0033] In this embodiment, the mounting chamber 1 consists of an upper chamber 1a disposed on the outer wall of the hopper and a lower chamber 1b disposed on the outer wall of the juice collection cup. The elastic push rod assembly 3 includes an upper push rod 3a disposed in the upper chamber 1a, and a first return spring 3b is vertically sandwiched between the upper push rod 3a and the upper chamber 1a. A pushing part is provided on the cover to cooperate with the upper end of the upper push rod. When the cover is opened, the return spring pushes the upper push rod upward; when the cover is closed, the pushing part on the cover pushes the upper push rod downward.

[0034] A push rod 3c is provided in the lower chamber 1b to cooperate with the locking assembly 2; the upper end of the push rod 3c is opposite to the lower end of the upper push rod 3a; in the initial state, the lower end of the upper push rod 3a is located above the lower end surface of the upper chamber 1a, and the upper end of the push rod 3c is located below the upper end surface of the lower chamber 1b. In this way, the upper push rod and the push rod will not affect the assembly of the components. When the upper push rod moves downward, it pushes the push rod down to cooperate with the locking assembly.

[0035] In this embodiment, preferably, the locking assembly 2 includes a locking seat 2a fixed in the lower chamber 1b, with locking buckles 2b symmetrically hinged on both sides of the locking seat 2a, and a torsion spring between the locking buckles 2b and the locking seat 2a; the push rod 3c is provided with a pressing part 2c corresponding to each of the two locking buckles 2b. In this embodiment, a vertical threaded mounting seat is provided in the lower chamber, and the locking seat is connected to the threaded mounting seat by screws. Alternatively, the locking seat can be fixed by connecting it to the side wall of the lower chamber by screws.

[0036] When the cover is open, the pressing part 2c does not press down on the latch 2b, and the latch 2b is in the open state under the action of the torsion spring, separating the latch 2b from the positioning seat 4. When the cover is closed, the pressing part 2c presses down on the latch 2b, and the latch 2b overcomes the torsion spring force and engages with the positioning seat 4. When the cover is closed, the push rod moves downward and presses down on the latch, causing the hook at the lower end of the latch to rotate inward and engage with the positioning seat. When the cover is open, the return spring causes the push rod to move upward, and the latch hook opens to both sides under the action of the torsion spring.

[0037] Of course, as those skilled in the art can see, by modifying the way the torsion spring and the latch are connected so that the latch is in the latched position in the initial state, and by modifying the other triggering structures accordingly, the same function as this utility model can be achieved. This is also an equivalent alternative that those skilled in the art can easily think of.

[0038] More preferably, the upper end of the latch 2b is provided with an inclined guide portion 2d, the top end of the inclined guide portion 2d is arc-shaped, and the pressing portion 2c is inclined downward with its inclined bottom surface conforming to the surface of the inclined guide portion 2d; when the pressing portion 2c presses down on the latch 2b, the top end of the inclined guide portion 2d slides along the bottom surface of the pressing portion 2c until the bottom surface of the pressing portion 2c is in close contact with the surface of the inclined guide portion 2d. By cooperating with the inclined downward pressing portion and the surface of the inclined guide portion, the pressing drives the latch to rotate.

[0039] In this embodiment, the lower end of the push rod 3c is integrally formed with a push portion 3d. Both the positioning buckle 4 and the locking assembly 2 are provided with clearance holes 3e that are adapted to the push portion 3d. A lower push rod 3f is provided in the main housing below the clearance hole 3e. A second reset spring is provided vertically between the lower push rod 3f and the main housing. The lower end of the lower push rod 3f corresponds to the micro switch on the circuit control board.

[0040] When the cover is open, the lower push rod 3f and the micro switch are in the released state, and the circuit on the circuit control board is disconnected; when the cover is closed, the lower push rod 3f presses down the micro switch, and the circuit on the circuit control board is turned on.

[0041] In use, place the movable cup body on the main unit housing, close the lid, and move the top rod downward to push the push rod. The downward pressing part of the push rod cooperates with the inclined guide part of the lock to make the lock rotate and engage with the positioning buckle to complete the assembly.

[0042] This utility model discloses a juicer, including a main housing 5, on which a movable cup 6 is detachably connected. A self-locking structure, as described above, is provided between the main housing 5 and the movable cup 6. This self-locking structure secures the movable cup to the main housing, improving stability during use and preventing the risk of loosening.

[0043] In this embodiment, preferably, the movable cup body 6 includes a juice collection cup 6a and a hopper 6b that cooperate with each other and are detachably connected, and a cover 6c is hinged to the opening of the hopper 6b.

[0044] The self-locking structure includes an upper chamber 1a disposed on the outer wall of the hopper 6b and a lower chamber 1b disposed on the outer wall of the juice collection cup 6a. A push rod 3c and a locking assembly 2 are disposed in the lower chamber 1b, and an elastic push rod assembly 3 is slidably disposed in the upper chamber 1a, which cooperates with the cover 6c and the push rod 3c.

[0045] A positioning buckle 4 that cooperates with the locking assembly 2 is integrally formed on the upper end of the main body housing 5; when the cover 6c is in the open state, the elastic push rod assembly 3 is at the upper limit of the stroke, and the locking assembly 2 is separated from the positioning buckle 4; when the cover 6c is in the closed state, the elastic push rod assembly 3 is at the lower limit of the stroke and presses the locking assembly 2 to make the locking assembly 2 engage with the positioning buckle 4.

[0046] By setting a mutually cooperating elastic push rod assembly and a locking assembly on the moving cup body, and setting a positioning buckle seat on the main body housing that cooperates with the locking assembly, the moving cup body and the main body housing are self-locked by a snap-fit ​​mechanism, which has the advantages of good self-locking stability and simple assembly.

[0047] More preferably, the elastic push rod assembly 3 includes an upper push rod 3a disposed in the upper chamber 1a, and a first return spring 3b vertically sandwiched between the upper push rod 3a and the upper chamber 1a; the lower end of the upper push rod 3a is opposite to the upper end of the push rod 3c, and in the initial state, the lower end of the upper push rod 3a is located above the lower end face of the upper chamber 1a, and the upper end of the push rod 3c is located below the upper end face of the lower chamber 1b; a pressing block 7 that cooperates with the upper push rod 3a is disposed on the outside of the hinge portion of the cover 6c and the hopper 6b. The pressing block cooperates with the upper end of the upper push rod, and when the cover is closed, the pressing block pushes the upper push rod downward; when the cover is opened, the first return spring pushes the upper push rod upward.

[0048] In use, place the movable cup body on the main unit housing, close the lid, push the upper rod downward by squeezing the squeeze block, and push the push rod down. The pressing part on the push rod cooperates with the inclined guide part of the lock to make the lock rotate and engage with the positioning buckle to complete the assembly.
