Description

Technical Field

[0001] The present invention relates to the technical field of juice extractors, and more particularly to a juice extractor with a feed cylinder. Background Art

[0002] Existing juice extractors come in various styles. For example, a citrus juicer has a structure including a main body, a filter screen, and a grinding head. The main body is provided with a base and a cup body. A motor is arranged on the base, and the cup body is installed on the base. The filter screen is placed at the upper opening of the cup body. One end of the grinding head connecting part is connected to the motor, and the other end extends upward out of the cup body and the filter screen. The motor drives the grinding head connecting part to rotate. During operation, the user presses a halved orange forcefully onto the grinding head, turns on the motor to drive the grinding head to rotate at high speed. The grinding head grinds the orange, and the orange juice flows into the cup body through the filter screen, while the orange residue falls on the filter screen, preventing it from entering the cup body to achieve juice-residue separation. However, the above-mentioned traditional citrus juicer with such a structure still has the following deficiencies: (1) When the citrus juicer is working, the user needs to press the orange down by hand so that the high-speed rotating grinding head can grind the orange. If the user is not careful, their hand is likely to touch the grinding head, so there is a certain safety hazard. (2) When the orange is ground in an open space, the juice and orange residue are likely to splash out. Moreover, when the orange is ground in an open space, the grinding effect is not ideal. Summary of the Invention

[0003] The object of the present invention is to overcome the deficiencies of the above-mentioned existing technologies, and to provide a juice extractor with safe use, no splashing of juice and fruit residue, and good grinding effect.

[0004] The object of the present invention is achieved as follows:

[0005] A juice extractor with a feed cylinder includes a main body and a grinding head assembly. The main body is provided with a grinding head connecting part, and the grinding head assembly is arranged on the grinding head connecting part so that the grinding head assembly is driven by the main body to rotate. Its feature is that it further includes a feed cylinder. The feed cylinder is placed on the main body and the grinding head assembly is located inside the feed cylinder. There is a grinding gap between the grinding head assembly and the inner side wall of the feed cylinder. For this type of juice extractor, by adding a feed cylinder and cooperating with the main body, the grinding head assembly is built into the feed cylinder. Therefore, the grinding process is carried out entirely inside the feed cylinder, avoiding the easy splashing of (ingredient) juice and fruit residue. Moreover, since there is a grinding gap between the grinding head assembly and the inner side wall of the feed cylinder, the grinding gap can improve the grinding effect. Also, since the grinding process is carried out entirely inside the feed cylinder, the user can use other tools (such as rods, sticks, etc.) to press the fruit grains inside the feed cylinder for grinding, avoiding the hand being easily in contact with the grinding head and thus eliminating the safety hazard, greatly improving the safety of its use.

[0006] The object of the present invention can also be solved by the following technical measures:

[0007] Further, a feed channel is provided on the feed cylinder. The inlet of the feed channel extends to the top of the feed cylinder, and its outlet is arranged at the bottom of the feed cylinder. The feed channel is oriented from the inlet to the outlet, and the width of the inlet of the channel is smaller than the width of its outlet. Such a feed channel that is narrower at the top and wider at the bottom not only suits the space required for arranging the grinding head assembly at the outlet of the feed channel but also facilitates the collection of fruit grains at the inlet of the feed channel first and then orderly entry into the grinding gap for processing, improving the grinding effect to a certain extent.

[0008] Further, the central vertical line of the feed channel coincides with the central vertical line of the grinding head assembly. In this way, the grinding can be made uniform. At the same time, the feed cylinder can be prevented from shaking or even detaching from the main machine due to uneven (grinding) force.

[0009] Further, the feed cylinder is a horn-shaped outer shell that is narrower at the top and wider at the bottom, and its grinding effect is better.

[0010] Further, a buckle is provided at the lower part of the feed cylinder. The feed cylinder is clamped on the buckle seat at the upper part of the main machine through the buckle, so that the feed cylinder is stably fixed on the main machine.

[0011] Further, a pressure rod is also included. The pressure rod is placed on the feed channel and abuts against the grinding head assembly. The user presses the fruit grains (or other food ingredients) in the feed cylinder through the pressure rod. The top of the grinding head assembly cooperates with the bottom of the pressure rod to conduct primary grinding on the food ingredients. The food ingredients after primary grinding slide down along the periphery of the grinding head assembly into the grinding gap, which not only speeds up the grinding progress but also prevents the hand from touching the grinding head assembly.

[0012] Further, a wear-resistant part is also provided between the bottom of the pressure rod and the top of the grinding head assembly. The setting of the wear-resistant part can prevent the grinding head assembly from being easily damaged.

[0013] Further, a protrusion for retarding the rotation of the food ingredients is provided at the bottom of the pressure rod to prevent the food from rotating too fast and affecting the grinding effect.

[0014] Further, a limiting flange extends outward from the upper part of the pressure rod. The lower part of the pressure rod is inserted into the feed channel, and its limiting flange is placed on the top of the inlet edge of the feed cylinder.

[0015] Further, the bottom of the pressure rod and the top of the grinding head assembly are in contact with each other in an arc surface or a flat surface. The arc surface cooperation is conducive to further improving the grinding effect, and the flat surface cooperation can also achieve the purpose of this patent.

[0016] Further, the grinding head assembly includes two or more grinding heads that are stacked and clamped to each other, and the lowermost grinding head is connected to the grinding head connecting portion; by providing two grinding heads that can be stacked and clamped (detachable) to each other, that is, including a first grinding head and a second grinding head, the user can either use the first grinding head alone to grind food ingredients, or stack the second grinding head on the first grinding head to achieve grinding of the food ingredients by the second grinding head, so as to meet different usage requirements. Moreover, since the second grinding head is stacked on the first grinding head here, the overall strength of the second grinding head is relatively high, it does not need to be made solid, so the cost is low, it can meet the grinding of relatively large fruits, and it is very convenient and easy to use.

[0017] Further, the main body includes a cup body, a motor assembly, and a filter screen. The motor assembly is fixed to the lower part of the cup body. A cup cavity is provided in the upper part of the cup body. The filter screen is placed at the upper opening of the cup cavity. The output shaft of the motor assembly constitutes the grinding head connecting portion. The grinding head connecting portion extends upward out of the cup cavity and the filter screen and then is connected to the grinding head assembly. The feeding tube is clamped on the edge of the filter screen; in this main body structure, the cup cavity is used to receive the juice, and the filter screen is used to receive the fruit residue, which is very convenient and reasonable.

[0018] Further, a slot is provided around the upper part of the filter screen, and a plug is provided at the lower part of the feeding tube. The plug of the feeding tube is inserted into the corresponding slot of the filter screen, so that the feeding tube is detachably arranged on the main body of the filter screen.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) For this juice machine, by adding a feeding tube and using the cooperation between the feeding tube and the main body, the grinding head assembly is built into the feeding tube. Therefore, the grinding process is carried out entirely within the feeding tube, avoiding the easy splashing of (food ingredient) juice and fruit residue. Moreover, since there is a grinding gap between the grinding head assembly and the inner side wall of the feeding tube, the grinding gap can improve the grinding effect. Also, since the grinding process is carried out entirely within the feeding tube, the user can use other tools (such as rods, sticks, etc.) to press down the fruit grains in the feeding tube to perform grinding, avoiding the potential safety hazard of the hand being easily in contact with the grinding head, and greatly improving the safety of its use.

[0021] (2) This kind of feeding channel that is narrow at the top and wide at the bottom not only suits the space required for setting the grinding head assembly at the outlet of the feeding channel, but also is conducive to the fruit grains gathering at the entrance of the feeding channel first and then orderly entering the grinding gap for processing, improving the grinding effect to a certain extent.

[0022] (3) The feeding tube is clamped on the buckle seat at the upper part of the main body through a buckle, so that the feeding tube is stably fixed on the main body.

[0023] (4) Additionally, a pressure bar is added. The pressure bar is placed on the feeding channel and abuts against the grinding head assembly. The user presses down on the fruit grains in the feeding cylinder through the pressure bar. The top of the grinding head assembly cooperates with the bottom of the pressure bar to initially grind the food ingredients. The food ingredients after the initial grinding slide downward along the periphery of the grinding head assembly into the grinding gap, which not only speeds up the grinding progress but also prevents the hand from touching the grinding head assembly.

[0031] The present invention will be further described below with reference to the drawings and embodiments.

[0032] Embodiment 1: As Figures 1 to 6As shown in the figure, a juicer with a feed tube includes a main body 1, a grinding head assembly 2, a feed tube 4, and a pressing rod 5. The main body 1 includes a cup body 11, a motor assembly 12, and a filter screen 13. The motor assembly 12 is fixed to the lower part of the cup body 11. There is a cup cavity 111 in the upper part of the cup body 11. The filter screen 13 is placed at the upper opening of the cup cavity 111. The output shaft of the motor assembly 12 forms the grinding head connection part 3. The grinding head connection part 3 extends upward from the cup cavity 111 and the filter screen 13 and is connected to the grinding head assembly 2 so that the grinding head assembly 2 is driven by the main body 1 to rotate. Among them, the feed tube 4 is a trumpet-shaped outer shell that is narrow at the top and wide at the bottom. There is a feed channel 41 on the feed tube 4. The inlet 42 of the feed channel 41 extends to the top of the feed tube 4, and its outlet 43 is arranged at the bottom of the feed tube 4. The feed channel 41 is in the direction from the inlet 42 to the outlet 43, and the width of the inlet 42 of its channel is smaller than the width of its outlet 43. The feed tube 4 is placed on the main body 1 and the grinding head assembly 2 is located inside the feed tube 4. There is a grinding gap 10 between the grinding head assembly 2 and the inner side wall of the feed tube 4. The pressing rod 5 is placed on the feed channel 41 and abuts against the grinding head assembly 2.

[0033] See Figure 2 and Figure 3 As shown in the figure, the central vertical line 411 of the feed channel 41 coincides with the central vertical line 211 of the grinding head assembly 2. There is a buckle 44 at the lower part of the feed tube 4. The feed tube 4 is clamped on the buckle seat 444 at the upper part of the main body 1 through the buckle 44 so that the feed tube 4 is fixed to the upper part of the main body 1.

[0034] As a more specific solution, there is also a wear-resistant part 6 between the bottom of the pressing rod 5 and the grinding head assembly 2; there are protrusions 51 at the bottom of the pressing rod 5 to retard the rotation of the food materials; the upper part of the pressing rod 5 extends outward to form a limit flange 52. The lower part of the pressing rod 5 is inserted into the feed channel 41, and its limit flange 52 is placed on the top edge of the inlet 42 of the feed tube 4; the bottom of the pressing rod 5 and the top of the grinding head assembly 2 are in contact with each other in an arc or flat surface.

[0035] As a more specific solution, the grinding head assembly 2 includes two or more grinding heads 21 that are stacked and clamped with each other. The lowermost grinding head 21 is connected to the grinding head connection part 3.

[0036] Working principle: Put food materials (such as fruit grains) into the feed tube 4, start the motor assembly 12 to drive the grinding head assembly 2 to rotate at a high speed. The user inserts the pressing rod 5 into the feed channel 41 of the feed tube 4. The top of the grinding head assembly 2 cooperates with the bottom of the pressing rod 5 to conduct primary grinding on the food materials. After the food materials are primarily ground, they slide downward along the periphery of the grinding head assembly 2 into the grinding gap 10. The food materials are subjected to secondary grinding by the outer side wall of the grinding head assembly 2 and the inner side wall of the feed tube 4 in the grinding gap 10. Then, the juice flows into the cup body 11 through the filter screen 13, and the fruit residue falls on the filter screen 13, preventing it from entering the cup body 11, thus realizing juice and residue separation.

[0037] Example 2: As Figure 7 shown, this embodiment is similar to Embodiment 1, and the only difference is the fixing method of the feed cylinder 4, that is: instead of the scheme in Embodiment 1 where the feed cylinder 4 is fixed to the snap seat 444 by the snap 44; in this embodiment, a slot 131 is provided around the upper part of the filter screen 13, and a plug 45 is provided at the lower part of the feed cylinder 4. The plug 45 of the feed cylinder 4 is inserted into the corresponding slot 131 of the filter screen 13 so that the feed cylinder 4 can also be fixed to the upper part of the main machine 1.
