Description

Technical Field

[0001] This utility model relates to a juicing system with a pre-cutting blade. Background Technology

[0002] With the improvement of people's living standards and increasing emphasis on healthy eating, the demand for homemade fresh fruit and vegetable juices continues to grow. Among the many juicing technologies, squeeze juicers are favored for their gentle working principle, low noise, and minimal oxidation of the juice.

[0003] A typical juicer includes a drive motor, a screw propeller, a filter cylinder, a juice outlet, and a pulp outlet. The specific working process is as follows: fruits and vegetables are fed into the juicer through the inlet and enter the pressing space under the influence of gravity and the screw propeller. They are mechanically squeezed, causing the juice to flow out through the filter screen on the pressing cylinder, while the pulp is pushed to the pulp outlet for discharge. However, when large fruits and vegetables such as apples and pears are put into the juicer, their large size makes it impossible for them to be grasped by the screw ridge and guided into the pressing chamber between the screw propeller and the filter cylinder. This requires manual intervention during juicing or spending a lot of time cutting them into small pieces before juicing, which is not only troublesome but also inefficient.

[0004] Chinese invention patent CN109602260B discloses a "spiral extrusion juicing screw for a juicer," which includes a screw and a filter assembly sleeved around the screw. The spiral portion on the outer surface of the screw forms an extrusion juicing section. The upper inner side of the extrusion juicing section and the interior of the filter assembly form a cavity for food to enter the filter assembly, thus allowing larger fruits to pass through. However, because the upper inner side of the extrusion juicing section and the top of the screw are smoothly connected in the form of a concave arc surface, fruits and vegetables are prone to spinning in the space between the upper inner side of the extrusion section and the lower side of the top of the screw, thus affecting the juicing efficiency. Utility Model Content

[0005] This invention provides a juicing system with a pre-cutting blade.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A juicing system with a pre-cutting blade includes a juicing cylinder with a receiving cavity inside. Inside the receiving cavity, a filter cylinder and a spiral propeller are arranged sequentially from the outside to the inside. A squeezing cavity is formed between the spiral propeller and the filter cylinder. The spiral propeller has a conical structure, and multiple outwardly protruding first spiral ridges and a second spiral ridge are arranged at intervals on its outer wall. The second spiral ridge extends spirally upward from the bottom to the top of the spiral propeller. A pre-cutting structure extends vertically upward from the top of the second spiral ridge. The pre-cutting structure includes a pre-cutting blade, the blade direction of which faces the rotation direction of the second spiral ridge, and a rib perpendicular to it is provided on the inner side of the pre-cutting blade.

[0008] Preferably, the top of the receiving cavity is provided with a top cover; and the top of the top cover is provided with a feed inlet.

[0009] Preferably, the juicer cylinder has a residue outlet and a juice outlet on opposite sides of its sidewall bottom.

[0010] Preferably, the multiple first spiral ridges all extend spirally upward from the bottom, and the lengths of the extensions are not equal.

[0011] Preferably, the outward convex width of the first and second spiral ridges gradually increases as the spiral ascends.

[0012] Preferably, the foremost end of the pre-cutting blade is provided with a blade tip, and an inwardly concave inner arc is provided below the blade tip.

[0013] Preferably, the outer side of the rib extends obliquely from the upper end of the pre-cutting blade to the top of the spiral propeller, and the rib has a structure that is wider at the bottom and narrower at the top.

[0016] Preferably, the filter cylinder is vertically continuous, the bottom end of the filter cylinder is inserted into the mounting groove, and multiple filter ports are arranged in a regular horizontal and vertical alignment on the side wall of the filter cylinder.

[0017] Compared with existing technologies, the juicing system with pre-cutting blade of this utility model has a pre-cutting system set at the top of the screw propeller. The pre-cutting blade can compress fruits and vegetables to the point of crushing, so that they can enter the squeezing chamber more easily as the screw propeller rotates. This not only improves the squeezing efficiency of fruits and vegetables, but also reduces the time users spend handling fruits and vegetables. The inner side of the pre-cutting blade is also provided with raised ribs, which play a role in pushing the fruits and vegetables and preventing them or the cut fruits and vegetables from spinning at the top of the screw propeller. This allows them to smoothly enter the squeezing chamber as the screw propeller rotates, thus improving the squeezing efficiency of fruits and vegetables. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, a juicing system with a pre-cut blade includes a juicing cylinder 1, an inner cavity 100, a filter cylinder 2 and a screw propeller 3 arranged sequentially from the outside to the inside inside the cavity 100; a top cover 101 is provided on the top of the cavity 100; a feed inlet is provided at the top of the top cover 101, and a space is provided inside to allow fruits and vegetables to stay briefly.

[0024] The juicer cylinder 1 has a pulp outlet 11 and a juice outlet 12 on opposite sides of the bottom of its side wall.

[0025] The bottom of the receiving cavity 100 is provided with a downwardly recessed mounting groove 102. The inner edge of the bottom of the mounting groove 102 is provided with a slag discharge channel opposite to the slag discharge port 11. The slag discharge channel connects the receiving cavity and the slag discharge port 11. The filter cylinder 2 is vertically continuous. The bottom of the filter cylinder 2 is inserted into the mounting groove 102. Multiple filter ports are arranged in a regular horizontal and vertical alignment on the side wall of the filter cylinder 2.

[0026] The bottom of the screw propeller 3 is connected to the motor. During installation, the screw propeller 3 is installed first, followed by the filter cartridge.

[0027] A squeezing chamber is formed between the spiral propeller 3 and the filter cylinder 2. The spiral propeller 3 is a conical structure, narrow at the top and wide at the bottom. Multiple outwardly protruding first spiral ridges 31 and one second spiral ridge 32 are arranged at intervals on the outer wall of the spiral propeller 3. The multiple first spiral ridges 31 extend spirally upward from the bottom, and the lengths of the extensions are not equal. The second spiral ridge 32 extends spirally upward from the bottom to the top of the spiral propeller 3. The outwardly protruding width of the first spiral ridge 31 and the second spiral ridge 32 gradually increases as the spiral rises. A pre-cutting structure 33 is provided vertically upward at the top of the second spiral ridge 32. The pre-cutting structure 33 includes a pre-cutting blade 331. The blade direction of the pre-cutting blade 331 is towards the rotation direction of the second spiral ridge 32. The front end of the pre-cutting blade 331 is provided with a blade tip, and an inwardly concave inner arc is provided below the blade tip for piercing fruits and vegetables before cutting.

[0028] The inner side of the pre-cutting blade 331 is provided with a rib 332 perpendicular to it. The outer side of the rib 332 extends obliquely from the upper end of the pre-cutting blade 331 to the top of the spiral propeller 3. Therefore, the rib 332 has a structure that is wider at the bottom and narrower at the top. The rib 332 plays the role of pushing the fruits and vegetables and preventing them from spinning at the top of the spiral propeller 3.

[0029] When using the juicer, fruits and vegetables enter from the top of the top cover 101 to the top of the screw propeller 3. The fruits and vegetables will rotate with the screw propeller 3. When the fruits and vegetables are large, and are subjected to pressure from the pre-cutting blade 331 and other fruits and vegetables or from the pre-cutting blade 331 and the inner wall of the juicer, the pre-cutting blade 331 will break them down into smaller pieces so that they can be better dragged into the squeezing chamber as the screw propeller 3 rotates. The ribs 332 play a role in pushing the fruits and vegetables to prevent the fruits and vegetables or the cut fruits and vegetables from spinning at the top of the screw propeller 3, thereby affecting the juice extraction efficiency.

[0030] This utility model's juicing system with a pre-cutting blade incorporates a pre-cutting system at the top of the screw propeller 3. The pre-cutting blade 331 can compress fruits and vegetables to the point of crushing, allowing them to enter the squeezing chamber more easily as the screw propeller 3 rotates. This improves the efficiency of fruit and vegetable juicing and reduces the time users spend processing fruits and vegetables. The inner side of the pre-cutting blade 331 is also provided with a protruding rib 332, which pushes the fruits and vegetables, preventing them or the cut fruits and vegetables from spinning at the top of the screw propeller 3. This ensures that the fruits and vegetables smoothly enter the squeezing chamber as the screw propeller 3 rotates, further improving the juicing efficiency.

[0031] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
