Description

Technical Field

[0001] This utility model relates to the technical field of juicing equipment, and more particularly to a juicer. Background Technology

[0002] Juicers, capable of processing fruits and vegetables into delicious beverages, have always been popular. With the improvement of living standards, juicers have moved from beverage shops into the kitchens of countless households, becoming an essential helper for enhancing people's quality of life.

[0003] Juicers typically require assembly before use and disassembly after use for cleaning and other operations. In existing juicers, the screw experiences significant reaction force from the material being pressed during the pressing process. This reaction force can potentially cause the working chamber to detach from the main unit. Therefore, improving the stability of the working chamber during pressing has always been a key issue for researchers in the industry. Utility Model Content

[0004] The purpose of this invention is to provide a juicer to solve the technical problem of stable operation of the juicer.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a juicer is provided, comprising: a main unit and a working chamber, the main unit being coupled to the working chamber, the working chamber being detachable from the main unit in a first direction, the working chamber including a pressing chamber, a screw being disposed within the pressing chamber, a power unit being disposed on the main unit, the power unit providing power to the screw, the axis of the screw being in the first direction, a storage groove being disposed on the main unit, a movable stop being disposed within the storage groove, a stop being disposed on the working chamber, the stop engaging with the movable stop, used to control the working chamber to be in a locked state or a detachable state in the first direction, the contact area between the movable stop and the stop being greater than or equal to 2.5 square millimeters.

[0006] This juicer utilizes movable stop components and stop positions to control the locking state of the working chamber. The stopping area of ​​the stop components and stop positions must not be less than 2.5 square millimeters to ensure their locking strength. If the stopping area is less than 2.5 square millimeters, the stop components may be structurally damaged by the reaction force of the screw, affecting the juicer's service life and operational stability.

[0007] Preferably, the aforementioned movable stop is U-shaped and surrounds the working chamber in at least three directions. This U-shaped movable stop can lock the working chamber at as many angles as possible, improving the locking stability of the working chamber during operation.

[0008] Preferably, the aforementioned movable stop includes two separate stops, which are located on both sides of the working chamber. These separate stops lock the working chamber from both sides, effectively securing it and ensuring its stability during operation.

[0009] Preferably, the main unit is equipped with a force-reducing rod, which is kinetically connected to the movable stop, controlling the movable stop to move into or out of the storage compartment. After use, residue may remain in the pressing chamber, pressing against the screw. Therefore, the screw still experiences significant reaction force, which keeps the movable stop firmly in place. When it needs to be released, it is difficult to control the movable stop to retract into the storage compartment. The force-reducing rod reduces the force required to retract the movable stop into the storage compartment.

[0010] More preferably, the lever arm ratio at both ends of the aforementioned force-reducing rod is between 2 and 50. The lever arm ratio refers to the ratio of the lever arm at the hand-controlled end of the force-reducing rod to the lever arm at the end of the force-reducing rod that contacts the movable stop. When the lever arm ratio at both ends of the force-reducing rod is less than 2, the force-reducing effect of the force-reducing rod is too small, and it cannot effectively retract the movable stop; when the lever arm ratio at both ends of the force-reducing rod is greater than 50, the stroke required for the force-reducing rod to operate is too long, and the force-reducing rod itself also needs to be very long, which is structurally inconvenient to implement.

[0011] Preferably, the screw is positioned near the power unit at its root, and a gap exists between the screw root and the inner wall of the pressing chamber. This gap prevents the screw root from rubbing against the inner wall of the pressing chamber, thus avoiding additional power loss on the screw.

[0012] Preferably, the screw is provided with a screw shaft, and the power unit is provided with a screw blind hole that mates with the screw shaft. The screw shaft abuts against the screw blind hole. The abutment between the screw shaft and the power unit ensures that the reaction force of the screw acts directly on the main unit, preventing friction on other parts of the screw and reducing power loss on the screw.

[0013] Preferably, the material strength of the aforementioned movable stop is greater than or equal to 1 kg / cm². 2 The material strength of the aforementioned movable stop is less than 1 kg / cm². 2 When this happens, the moving stop is easily damaged by the reaction force, affecting the lifespan of the juicer.

[0014] Preferably, the movable stop is provided with an elastic member, which controls the movable stop to be in a state where it is normally outside the recess. This elastic member keeps the movable stop in a normally locked state, reducing the structural complexity of controlling its movement.

[0015] More preferably, when the aforementioned movable stop is locked in the working chamber and the main unit, the elastic force provided by the elastic component is between 0.5N and 100N. When the elastic component is in the relaxed state, if the elastic force provided by the elastic component is less than 0.5N, the locking state will not be stable enough, and the movable stop and elastic component may retract due to slight shaking of the working chamber. At the same time, the movable stop may easily get stuck when it pops out. When the elastic force provided by the elastic component is greater than 100N, the force required to control the retraction of the movable stop is too large, which is not conducive to the control of the movable stop.

[0043] Example 1:

[0044] like Figures 1-3 As shown, Figure 1 This is a cross-sectional view of the juicer 1000 according to Embodiment 1 of this utility model. Figure 2 This is a three-dimensional structural diagram of the storage compartment 1121 of the juicer 1000 according to Embodiment 1 of this utility model. Figure 3 This is a three-dimensional structural diagram of the working chamber 1200 of the juicer 1000 according to Embodiment 1 of this utility model.

[0045] This embodiment discloses a juicer 1000, including a main unit 1100 and a working chamber 1200. A power unit 1110 is provided on the main unit 1100. A pressing chamber 1210 is provided inside the working chamber 1200, and a screw 1211 is provided inside the pressing chamber 1210. The power unit 1110 provides power to the screw 1211. The working chamber 1200 can detach from the main unit 1100 in direction E.

[0046] A screw shaft 1213 is provided on the screw 1211, extending from the working chamber 1200 and capable of slight axial movement. A screw blind hole 1111 is provided on the power unit 1110, and the screw shaft 1213, being a hexagonal shaft, mates with the screw blind hole 1111. When the working chamber 1200 is finally assembled onto the main unit 1100, the screw shaft 1213 abuts against the bottom of the screw blind hole 1111 to prevent axial movement of the screw shaft 1213 or friction with the inner wall of the working chamber or other components, thereby reducing power loss. The portion of the screw 1211 near the power unit 1110 is the screw root 1212, and a gap exists between the screw root 1212 and the inner wall of the working chamber 1200.

[0047] The main unit 1100 is provided with a recess 1121, and a movable stop 1122 is provided within the recess 1121, which can extend out from the recess 1121. The working chamber 1200 is provided with a stop position 1220, which cooperates with the movable stop 1122 to lock the working chamber 1200 onto the main unit 1100. The contact area between the locking end face of the stop position 1220 and the movable stop 1122 is 2.5 square millimeters. The movable stop 1122 has a U-shaped structure, covering three directions of the working chamber 1200, and the corresponding stop position 1220 has an inverted U-shaped groove to accommodate the insertion of the U-shaped movable stop 1122. The main unit 1100 is also equipped with a damping rod 1123, which is connected to a movable stop 1122 and can control the movable stop 1122 to retract into the recess 1121. The lever arm ratio between the hand-controlled end of the damping rod 1123 and the end connected to the movable stop 1122 is 2. In other embodiments, the lever arm ratio between the hand-controlled end of the damping rod and the end connected to the movable stop can also be 50.

[0048] The movable stop 1122 is made of plastic with a material strength of 1 kg / cm². 2 A spring-loaded member 1124 is provided below the movable stop 1122. The spring-loaded member 1124 provides an upward elastic force to the movable stop 1122 so that the movable stop 1122 remains extended from the recess 1121. When the movable stop 1122 is kept in the extended state, the elastic force is 0.5N.

[0049] In this embodiment, the juicer 1000, by setting the movable stop 1122 and its related components, ensures that the working chamber 1200 is locked onto the main unit 1100 during pressing, maintaining stable operation and preventing it from disengaging from the main unit 1100 due to the reaction force of the screw 1211 along the E direction. Simultaneously, the locking contact area and material strength of the movable stop 1122 ensure that it will not be damaged by prolonged reaction force, thus guaranteeing its service life. Furthermore, the design of the force-reducing rod 1123 prevents the working chamber 1200 from being tightly pressed against the movable stop 1122 when cleaning after juicing, as residue may still be present inside the pressing chamber 1210, preventing the movable stop 1122 from retracting. The force-reducing rod 1123 effectively solves this problem.

[0050] Example 2:

[0051] like Figure 4 The diagram shown is a cross-sectional view of the end face of the juicer 2000 according to Embodiment 2 of this utility model.

[0052] This embodiment discloses a juicer 2000, including a main unit 2100 and a working chamber 2200. A power unit 2110 is provided on the main unit 2100. The juicer 2000 of this embodiment has a basically the same structure as the juicer 1000 of Embodiment 1 of this utility model, with the following differences.

[0053] The main unit 2100 is provided with a recess 2121 to accommodate a movable stop 2122, which extends from the recess 2121 toward the working chamber 2200 outside the main unit 2100. The working chamber 2200 is provided with a stop 2220, which cooperates with the movable stop 2122 to lock the working chamber 2200 onto the main unit 2100. The movable stop 2122 consists of two separate stops 2125, which lock the working chamber 2200 from both sides. The contact area between the locking end face of the stop 2220 and the movable stop 2122 is 3 square millimeters. The main unit 2100 is also equipped with a damping rod 2123, which is connected to the movable stop 2122 through a gear structure. The lever arm ratio between the manual control end of the damping rod 2123 and the end connected to the movable stop 2122 is 2.5.

[0054] The movable stop 2122 is made of plastic with a material strength of 1.3 kg / cm². 2 The damping rod 2123 is provided with an elastic member 2124, which controls the movable stop 2122 to remain extended from the recess 2121. The elastic force of the elastic member 2124 in keeping the movable stop 2122 extended is 1N. In other embodiments, this elastic force can be 100N.

[0055] The juicer 2000 of this embodiment has essentially the same effect as the juicer 1000 of Embodiment 1.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
