Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and particularly to a pit-removing juicer. Background Art

[0002] A juicer is a machine that can quickly extract fruit and vegetable juice from fruits and vegetables. It is small in size and simple to operate, and is very popular among people. Currently, the commonly used juicer mainly consists of a motor, a cutter head, a filter screen, a cover body, and a container, etc. The cutter head is connected to the motor and driven by the motor to rotate, and is used to cut the materials placed in the container to extract the juice. The filter screen is used to filter the flowing juice to obtain pure and impurity-free fruit and vegetable juice. The cover body is covered on the container to prevent people from accidentally reaching into the container and getting injured. However, before juicing fruits and vegetables with the existing juicer, it is necessary to manually remove the hard fruit cores, which is time-consuming and laborious. For example, apricots, peaches, plums, etc. all have relatively large and hard cores, and these cores are likely to damage the cutter head during the cutting process. At the same time, the dregs formed by the broken cores will also greatly affect the taste of the fruit and vegetable juice.

[0003] Therefore, it is urgent to design a pit-removing juicer to solve the above problems existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to provide a pit-removing juicer, which can automatically separate the pulp from the fruit cores during the juicing process without manual pit removal.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The present invention provides a pit-removing juicer, including:

[0007] A crushing mechanism, which can rotate and cut the materials;

[0008] A surrounding cylinder, which surrounds the upper part of the crushing mechanism. The surrounding cylinder has a feeding port and a crushing port, the crushing port is arranged opposite to the crushing mechanism, and the side wall of the surrounding cylinder is provided with a pit outlet.

[0009] A filter screen, there is a seepage channel between the crushing mechanism and the surrounding cylinder, and the filter screen is arranged opposite to the seepage channel.

[0010] Preferably, the size of the pit outlet is adjustable.

[0011] Preferably, the side wall of the surrounding cylinder is provided with a sliding groove, and a plurality of clamping grooves are distributed along the extension direction of the sliding groove on the side wall of the surrounding cylinder;

[0012] A baffle is slidably arranged in the chute. The baffle is used to cover the nuclear outlet hole. A buckle is arranged on the baffle, and the buckle is clamped in the clamping groove.

[0013] Preferably, the nuclear-free juicer further includes a filter net bowl. The crushing mechanism is arranged on the bottom surface of the cup of the filter net bowl, and the filter net is arranged on the filter net bowl.

[0014] Preferably, the maximum distance between the crushing mechanism and the bottom surface of the cup is the cutting distance h. Along the vertical direction, the distance between the end of the crushing port and the bottom surface of the cup is less than the cutting distance h.

[0015] Preferably, an avoidance groove is formed by the depression of the edge of the crushing mechanism. The end of the crushing port is inserted into the avoidance groove vertically, and a seepage channel is formed between the end of the crushing port and the avoidance groove.

[0016] Preferably, the nuclear-free juicer further includes a residue bucket and a drainage retaining ring. The drainage retaining ring surrounds the upper edge of the filter net bowl. A flow channel is formed by enclosing between the drainage retaining ring and the upper edge of the filter net bowl. The residue bucket is arranged opposite to the outlet of the flow channel.

[0017] Preferably, the nuclear-free juicer further includes a liquid collection cup. The liquid collection cup is arranged vertically below the filter net.

Since the surrounding cylinder has a feeding port and a crushing port, and the crushing port is arranged opposite to the crushing mechanism, users can put materials through the feeding port onto the crushing mechanism below for cutting to extract juice. During the juicing process, the fruit pits of the materials will be separated from the pulp under the cutting of the crushing mechanism, and under the rotation of the crushing mechanism, they will be driven by centrifugal force to be thrown onto the side wall of the surrounding cylinder. Since the side wall of the surrounding cylinder is provided with pit-discharging holes, the fruit pits will be discharged from the surrounding cylinder through the pit-discharging holes, separating from the pulp inside the surrounding cylinder to achieve the effect of automatically removing pits and extracting juice. Since there is a seepage channel between the crushing mechanism and the surrounding cylinder, and the filter screen is arranged opposite to the seepage channel, the liquid generated after the pulp is cut will flow into the filter screen through the seepage channel, and thus pure and residue-free juice can be obtained after filtration. This pit-removing juicer has a simple structure, can separate the pulp from the fruit pits during the juicing process to achieve automatic pit removal, without the need for manual pit removal before juicing, saving time and effort, and at the same time can prevent the fruit pits from damaging the crushing mechanism.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0040] Such as Figures 1 to 3As shown in the figure, the present invention provides a pit-removing juicer, which includes a crushing mechanism 1, a surrounding cylinder 2 and a filter screen. The crushing mechanism 1 can rotate and cut the materials; the surrounding cylinder 2 surrounds the upper part of the crushing mechanism 1. The surrounding cylinder 2 has a feeding port and a crushing port, and the crushing port is arranged opposite to the crushing mechanism 1. There are pit-discharging holes 21 on the side wall of the surrounding cylinder 2; there is a seepage channel between the crushing mechanism 1 and the surrounding cylinder 2, and the filter screen is arranged opposite to the seepage channel. In this embodiment, since the surrounding cylinder 2 has a feeding port and a crushing port, and the crushing port is arranged opposite to the crushing mechanism 1, the user can put the materials through the feeding port onto the lower crushing mechanism 1 for cutting to extract juice; during the juice extraction process, the fruit pits of the materials will be separated from the pulp under the cutting of the crushing mechanism 1, and will be driven by the centrifugal force under the rotation of the crushing mechanism 1 and thrown onto the side wall of the surrounding cylinder 2. Since there are pit-discharging holes 21 on the side wall of the surrounding cylinder 2, the fruit pits will be discharged from the surrounding cylinder 2 through the pit-discharging holes 21 and separated from the pulp in the surrounding cylinder 2, so as to achieve the effect of automatically removing pits and extracting juice; since there is a seepage channel between the crushing mechanism 1 and the surrounding cylinder 2, and the filter screen is arranged opposite to the seepage channel, the liquid generated after the pulp is cut will flow into the filter screen through the seepage channel, and thus pure and residue-free juice can be obtained after filtration. This pit-removing juicer has a simple structure, can separate the pulp from the fruit pits during the juice extraction process to achieve automatic pit removal, without manual pit removal before juice extraction, which saves time and effort, and can also prevent the fruit pits from damaging the crushing mechanism 1.

[0041] Specifically, the crushing mechanism 1 is a cylindrical cutter head structure. There are raised blades on the upper surface of the cutter head body, and the cutter head rotates to drive the blades to cut the materials; the surrounding cylinder 2 is a cylindrical structure, and there is a gap between the surrounding cylinder 2 and the crushing mechanism 1 in the vertical direction to form a seepage channel. When extracting juice, the user puts the materials into the surrounding cylinder 2 from the feeding port, and the materials fall onto the crushing mechanism 1 through the crushing port. The crushing mechanism 1 rotates to cut the materials to extract juice; it can be understood that the surrounding cylinder 2 remains fixed during the juice extraction process and plays a role in enclosing the materials on the crushing mechanism 1.

[0042] In order to be applicable to different types of pitted materials, the size of the pit-discharging holes 21 is adjustable; it can be understood that when extracting juice from different materials, the size of the pit holes 21 can be adjusted according to the size of the fruit pits inside the materials. For example, when extracting juice from peaches and cherries respectively, the size of the pit-discharging holes 21 needs to be adjusted to the size of peach pits and cherry pits to avoid the peach pits being unable to be discharged due to the too small pit-discharging holes 21, and at the same time, it can also avoid the excess pulp or juice flowing out of the pit-discharging holes 21 due to the too large pit-discharging holes 21.

[0043] The adjustment method of the size of the pit-discharging holes 21 can be set according to actual needs as long as different-sized fruit pits can pass through. Exemplarily, such as Figure 2 and Figure 3As shown in the figure, a chute 22 is provided on the side wall of the surrounding cylinder 2, and a number of clamping grooves 23 are distributed along the extension direction of the chute 22 on the side wall of the surrounding cylinder 2; a baffle 24 is slidably arranged in the chute 22, and the baffle 24 is used to cover the nuclear outlet hole 21. A buckle 241 is provided on the baffle 24, and the buckle 241 is clamped in the clamping groove 23. Specifically, the shape of the nuclear outlet hole 21 is circular or oval. The chute 22 extends in the vertical direction, and a number of clamping grooves 23 are evenly distributed vertically. The baffle 24 is inserted into the chute 22 and can slide along the chute 22. The baffle 24 is positioned through the clamping groove 23. Before juicing, the user can adjust the position of the baffle 24 according to the size of the fruit pits in the material to adjust the shielding area of the nuclear outlet hole 21, and clamp the buckle 241 of the baffle 24 in the corresponding clamping groove 23, so as to realize the adjustment of the size of the nuclear outlet hole 21.

[0044] In this embodiment, the area of the baffle 24 is larger than the area of the nuclear outlet hole 21. When the baffle 24 is completely lowered vertically, the baffle 24 can completely cover the nuclear outlet hole 21. At this time, it is suitable for juicing materials without fruit pits to prevent the pulp or juice from accidentally flowing out of the nuclear outlet hole 21.

[0045] As Figure 2 、 Figure 4 and Figure 5 As shown in the figure, the pit-removing juicer further includes a filter net bowl 3. The crushing mechanism 1 is arranged on the bottom surface of the cup of the filter net bowl 3, and the filter net is arranged on the filter net bowl 3; specifically, the filter net bowl 3 is a trumpet-shaped structure with a single-sided opening, the opening of the filter net bowl 3 is arranged upward, the bottom surface of the cup of the filter net bowl 3 is a plane, the crushing mechanism 1 is installed on the bottom surface of the cup, and the filter net bowl 3 can drive the crushing mechanism 1 to rotate synchronously to realize the cutting of the material. The filter net is arranged on the side wall of the filter net bowl 3. The squeezed liquid flows into the filter net bowl 3 from the seepage channel and flows out after being filtered by the filter net, and the dregs will remain in the filter net bowl 3.

[0046] As Figure 4 and Figure 5As shown, the maximum distance between the crushing mechanism 1 and the bottom surface of the cup is the cutting distance h. Vertically, the distance between the end of the crushing opening and the bottom surface of the cup is less than the cutting distance h. In this embodiment, the end of the crushing opening of the surrounding cylinder 2 is the lower edge of the surrounding cylinder 2. The crushing mechanism 1 is a cylindrical cutter head structure. Blades are provided on the upper surface of the cutter head body. The distance between the top of the blade and the bottom surface of the filter net bowl 3 is the cutting distance h. Since the cutting distance h is greater than the distance between the lower edge of the surrounding cylinder 2 and the bottom surface of the cup, at this time, a downward seepage channel is formed between the crushing opening of the surrounding cylinder 2 and the crushing mechanism 1, and the inlet of the seepage channel is in the horizontal direction. Compared with the seepage channel with a vertical inlet, this design can prevent the fruit pits of the material from flying out under the action of centrifugal force during the rotation and agitation of the crushing mechanism 1 and getting stuck in the seepage channel, ensuring the effective separation of the fruit pits and the smooth progress of juice extraction, thus greatly improving the practicability of this pit-free juice extractor.

[0047] As Figure 1 and Figure 5 shown, a relief groove is formed by the depression at the edge of the crushing mechanism 1. The end of the crushing opening is inserted vertically into the relief groove, and a seepage channel is formed between the end of the crushing opening and the relief groove. Specifically, the crushing mechanism 1 is a cylindrical cutter head structure. The edge of the cutter head body is recessed to form a relief groove with an L-shaped cross-section. The end of the crushing opening of the surrounding cylinder 2 is inserted into the relief groove, but the surrounding cylinder 2 does not contact the crushing mechanism 1, and the surrounding cylinder 2 remains fixed and does not rotate during the juice extraction process.

[0048] In order to better collect the residue remaining after the material is juiced after the juice extraction is completed, as Figure 1 and Figure 2 shown, the pit-free juice extractor further includes a residue bucket 5 and a drainage retaining ring 6. The drainage retaining ring 6 is arranged around the upper edge of the filter net bowl 3. A flow channel is formed by enclosing between the drainage retaining ring 6 and the upper edge of the filter net bowl 3. The residue bucket 5 is disposed directly opposite the outlet of the flow channel. Specifically, the drainage retaining ring 6 is arranged around the upper edge of the filter net bowl 3, thus forming a flow channel between the upper end of the filter net bowl 3 and the drainage retaining ring 6. During the juice extraction process, the remaining juice after the material is juiced will enter the filter net bowl 3 through the seepage channel. As the residue accumulates, the overflowing residue will flow upward and enter the flow channel. Since the outlet of the flow channel is directly opposite the residue bucket 5, the residue will eventually enter the residue bucket 5, thus completing the automatic collection.

[0049] As Figure 1 、 Figure 2 and Figure 4As shown, the pit-removing juicer further includes a liquid collection cup 4. The liquid collection cup 4 is vertically arranged below the filter screen. The liquid collection cup 4 is used to collect the juice extracted from the material and filtered by the filter screen. Specifically, the liquid collection cup 4 is arranged below the filter net bowl 3, and the filter screen is arranged on the side wall of the filter net bowl 3. After the liquid extracted from the material by cutting and stirring of the crushing mechanism 1 passes through the filter screen of the filter net bowl 3, it will flow into the lower liquid collection cup 4, thus automatically completing the collection of the juice.

[0050] Furthermore, an outflow nozzle 41 is provided on the liquid collection cup 4, and the filtered and collected juice will flow out from the outflow nozzle 41, thus facilitating the user to drink.

[0051] Furthermore, one or more pit outlet holes 21 can be provided according to actual needs. In this embodiment, a plurality of pit outlet holes 21 are provided. The plurality of pit outlet holes 21 are arranged at intervals on the cylinder 2, and the shapes of all the pit outlet holes 21 are the same. And a baffle 24 is provided corresponding to each pit outlet hole 21. Therefore, the size of each pit outlet hole 21 can be adjusted. The plurality of pit outlet holes 21 can improve the separation speed of the fruit pits, and further improve the practicability of the pit-removing juicer.

[0052] As Figure 4 and Figure 5 shown, the pit-removing juicer further includes a driving mechanism 7. The output shaft of the driving mechanism 7 is connected to the crushing mechanism 1, and the driving mechanism 7 drives the crushing mechanism 1 to rotate. Specifically, the driving mechanism 7 is a commonly used driving motor in the art. The crushing mechanism 1 is installed in the filter net bowl 3. The liquid collection cup 4 is arranged below the filter net bowl 3 and the liquid collection cup 4 has a through central channel. The output shaft of the driving mechanism 7 passes through the central channel and is connected to the filter net bowl 3. After the driving mechanism 7 is started, the output shaft drives the filter net bowl 3 to rotate, thereby driving the crushing mechanism 1 to rotate to cut the material. In this embodiment, the overall working process of the pit-removing juicer during juicing is roughly as follows: First, the user puts the material into the feeding port of the cylinder 2 and adjusts the size of the pit outlet hole 21 according to the size of the fruit pits of the material to ensure that the fruit pits can pass through the pit outlet hole 21. Then the driving mechanism 7 is started. The driving mechanism 7 drives the crushing mechanism 1 to rotate through the filter net bowl 3 to cut the material entering the crushing port. The pulp and the fruit pits are separated under the cutting and stirring of the crushing mechanism 1. The fruit pits are thrown out under the action of centrifugal force during the rotation and stirring of the crushing mechanism 1 and will be discharged into the filter net bowl 3 through the pit outlet holes 21 on the cylinder 2. At the same time, the pulp will be further cut by the crushing mechanism 1 to extract the juice. The juice and the remaining dregs will flow into the outer filter net bowl 3 together through the seepage channel. Since the side wall of the filter net bowl 3 is provided with a filter screen, the juice will continue to flow into the lower liquid collection cup 4 through the filter screen, while the dregs will remain in the filter net bowl 3. As the juicing continues, the dregs in the filter net bowl 3 will enter the slag bucket 5 through the flow channel for unified collection, and the juice will be collected in the liquid collection cup 4 and flow out through the outflow nozzle 41.

[0053] Furthermore, as Figure 2 shown, the juicer without a core also includes a top cover 8, which is covered on the liquid collection cup 4 and the residue bucket 5 to prevent external sundries from contaminating the juice in the liquid collection cup 4 and to avoid splashing of residues and juice during the juicing process. Moreover, the top cover 8 is connected to the surrounding cylinder 2. When the top cover 8 is covered on the liquid collection cup 4 and the residue bucket 5, the surrounding cylinder 2 surrounds the crushing mechanism 1 and a seepage channel is formed between them.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
