Description

Fruit and vegetable juicer without core cleaning

Technical field

The invention relates to a juice extracting device for a fruit and vegetable juice, in particular to a fruit and vegetable juice extracting machine which is free of nuclear no-cleaning.

Background technique

With the improvement of people's living standards and the gradual deepening of the concept of health, more and more consumers have abandoned all kinds of “additive” beverages and turned to fruit and vegetable juices that have pure natural color, fragrance and rich in essential vitamins and trace elements. stand up. But if you want to have a good cup of freshly squeezed fruit and vegetable juice every morning, a suitable juicer is essential. At the same time, with the improvement of the quality of life, the consumer's mentality begins with the most basic life needs to transition to a nutritious and healthy taste life, which provides more possibilities for the popularization and upgrading of juicers.

There are two kinds of existing juicers: one is a high-speed rotating motor that drives the cutter head and the filter net, and the cutter disc pulverizes the food and then centrifuges the juice through the filter at high speed, such as Chinese patent CN101048071A, CN102783903A. The disclosed juicer, but such a processing method is because the food is quickly scooped out, the juice yield is relatively low, the processing efficiency is poor, and the juice component is destroyed due to the high speed juice, which affects the taste and nutrition of the juice. The improvement made to this juicer is to use a high-speed or low-speed motor to drive the cutter head and the cylindrical juice cylinder. After the cutter is used to smash the food, the food residue is simmered in the juice tank for a long time, which can increase the juice yield. . However, the following problems still exist: the pomace is accumulated in the juice tank, and cannot be discharged when the juicer is working normally. After working for a certain period of time, the juice bottle is filled with the pomace, and the juicer must be stopped to clean the juice. The tube is further processed; the pomace is accumulated in the juice tank, and the first processed poma will block the juice outlet, affecting the normal processing of the food after the processing, but will cause the juice rate to decrease; the pomace is in the juice tank for a long time. The glutinous juice will also cause the nutrients of the juice to be destroyed, affecting the nutrition and taste of the juice; the slag will accumulate in the sputum juice tank. Due to the randomness of processed food and food input, the Marc will not be evenly distributed inside the mashed juice cylinder. It will cause the juice tank to vibrate during work and increase the noise when the juicer works. The pomace is accumulated in the juice tank. In order to ensure that the subsequent juice can be removed, the side wall of the juice can only use the filter. The pomace is centrifuged for a long time in the juice tank, and some of the pomace will enter the filter mesh hole. It will be more difficult to clean the filter net, which is not conducive to the user's use.

The other is a juice machine, such as the screw squeeze type juicer disclosed in Chinese Patent No. CN103202655A. The difference between the juice machine currently on the market and the previous first juicer is that it is based on the principle of stone grinding. Juice, absolutely low speed, 70-80 transfer per minute, you can rest assured that it will not destroy nutrients, 100% retains activity, because the nutrients of fruit and vegetable juices are particularly weak against temperature, it is said that more than 40 degrees is not fresh, more Moreover, thousands of revolutions per minute, the destruction of high speed and high temperature in an instant; secondly, the biggest difference between the juice machine and other juicers is that it satisfactorily solves the separation of pesticides and heavy metals from active juices because of the high proportion of pesticides and heavy metals. The specific gravity of water is only absorbed in the juice by pressing it on the fiber. If the first juicer mentioned above pulverizes the fiber into a crushed foam, it is inevitable that the juice and the powder are mixed together, and then the centrifugal mash is actually used to keep the medicine and the heavy metal powder from being completely preserved. The liquids are mixed together. The juice machine squeezes heavy metals and pesticides together with the fibers to discharge the slag. In fact, pesticides and heavy metals and fibers have a good affinity. It is adhered to the fruits and vegetables with the growth of fruits and vegetables. In addition to the extrusion of the gears, it is integrated, so the extruded is completely non-toxic active juice.

However, the juice machine currently used still has the following problems when it is used: the filter screen and the slag discharge port still exist, so there is still a problem that it is difficult to clean after the juice is extracted. In addition, the filter screen needs to be installed, and the installation and replacement are also very inconvenient. Also, because the residue is squeezed into the slag discharge tank at the bottom, in the case where it takes a long time to continuously extract the juice, the residue is likely to accumulate at the bottom of the filter screen, resulting in poor juice extraction effect, and the mixing of several juices affects the taste. .

The guide plate 87 is provided with a vertically extending guiding groove 871. The front and rear ends of the hinge shaft 933 of the hinge plate 93 are respectively inserted in the guiding groove 871. Inside. And moving along the guide groove 871. As shown in FIGS. 13a, 13b, and 13c, in the state of one, since the rack 83 drives the upper and lower top plates to move upward together, the hinge shaft 933 of the hinge plate 93 is located at the top of the guide groove 871. The guide groove 871 corresponds to the hinge plate 93 as two left and right sides, and extends outward from the top to the bottom. At the same time, the opposite inner surfaces of the two side plates 11 are provided with guide rails 111 extending upward and downward to the inner surface of the side plates 11. The guide rails 111 are matched with the lower top plate 92, that is, the two sides of the lower top plate 92 are respectively provided with When the guide rails 111 are matched with the recesses 925 and the lower top plate 92 moves up and down along the guide rails 111, the outer ends of the sliders 94 below the lower top plate 92 abut against the guide rails 111 on both sides.

As shown in FIG. 14a and FIG. 14b, the rack 83 drives the upper and lower top plates to move up to the state 2, and the side plates 11 are spaced apart above the top of the guide rail 111 with inwardly projecting stops 112, and the stops 112 are respectively located below.

That is, as the rack 83 is upward, the second driving plate 85 and the guiding plate 87 simultaneously drive the hinge plates 93 to unfold each other, thereby causing the upper top plate 91 to be ejected upward. And the upward pressure of the upper top plate 91 is transmitted to the guide rails 111 on both sides through the lower top plate 92 and the slider 94, and is transmitted to the side plates 11, so that the rack 83 is increased in the supercharging and rising mechanism. During the pressing process, the pressure is small, and therefore, the service life of the rack 83 is also increased.

When the juice is completed, the motor is reversed, the rack 83 is lowered, and the state is changed from the state 3 to the state 2, and the guide plate 87 moves downward with the rack 83, thereby driving the hinge plate 93 to be folded downward, which in turn drives the upper top plate 91 downward. After the movement to the state 2, the rack 83 continues to descend, so that the first driving plate 84 is downward and the top end 841 of the first driving plate 84 is retracted against the slider 94, and the slider 94 is biased by the tension spring 95. The intermediate retraction, which in turn drives the lower top plate 92, also begins to descend with the rack 83, to state one, and then returns to the original state.

The pressure adjusting mechanism 40 includes an undercover 402 located below the upper beam 4 and spaced apart from the upper beam 4 to form an accommodating space and movable up and down relative to the upper beam 4, and an accommodating space between the bottom cover 402 and the upper beam 4 The first rotating member 404 is fixedly connected to the upper beam 4, and the second rotating member 405 is disposed on the bottom surface of the bottom cover 402. The first rotating member 404 and the second rotating member 405 are as shown in FIG. As shown in FIG. 18, each includes an

annular body

4041, 4051. One end of the

annular body

4041, 4051 is a flat surface, and the other end is formed with a plurality of

tooth shapes

4042, 4052, and at least one side of the tooth shapes 4042, 4052 is a spiral surface. As shown in FIG. 17, one side of the tooth forms 4042, 4052 is a

spiral surface

4044, 4054, and the other side is a vertical plane perpendicular to the plane of one end of the annular body 4041. The tooth shapes of the first rotating member 404 and the second rotating member 405 are oppositely disposed, and the tooth shapes are matched with each other, that is, the spiral surfaces 4044, 4054 are oppositely disposed and disposed, and thus, the first rotating member 404 and the second rotating member The first frictional force f1 is a fixed value between the spiral faces 4044 and 4054 of the 405, and is determined by the material and the roughness of the two faces of the first rotating member 404 and the second rotating member 405, and The tooth profiles are offset from one another by a certain distance.

The first rotating member 404 and the second rotating member 405 are further inserted with a rotating member 401 that can move up and down. The inner side of the first rotating member 404 is also fixedly provided with a damping seat 408. The damping seat 408 is located at the rotating member 401. Above, and the damping seat 408 and the upper surface of the rotation preventing member 401 cooperate with each other to have a second frictional force f2, the second frictional force f2 can be adjusted by adjusting the upper and lower positions of the rotation preventing member 401 with respect to the damping seat 408. There are a plurality of ways of moving up and down the 401. In the embodiment, the top of the 401 is connected to a connecting shaft 407 that can move up and down. The connecting shaft 407 can move the rotating member 401 up and down and the rotating member The 401 is rotatable relative to the connecting shaft 407. The connecting shaft can be screwed to the upper beam 4 for lifting up and down. However, it is preferable that the connecting shaft 407 protrudes from the outer side of the upper beam 4 and is hinged with a lever for driving up and down. The connecting shaft 407 is connected, that is, the connecting shaft 407 is used to adjust the height position of the rotation preventing member 401 with respect to the damper seat 408. The bump 4011 at the bottom of the rotation preventing member 401 is a member having different length and width, and the end surface of the annular body 4051 of the second rotating member 405 has a hole 4053 matching the shape of the projection of the rotation preventing member 401, thereby stopping The protrusion 4011 of the rotary member 401 is inserted into the hole 4053 of the second rotating member 405, and can rotate simultaneously with the rotation of the second rotating member 405, but does not rise as the second rotating member 405 rises.

Since the spiral surfaces of the tooth shapes of the first rotating member 404 and the second rotating member 405 are in close contact with each other, when the moving beam 3 lifts up the fruits and vegetables, and the fruits and vegetables are pushed to the pressure adjusting mechanism 40, the two begin to squeeze. Press the fruit and vegetable out of the juice, as shown in Figure 11. As the moving beam 3 is further raised, the pressure on the fruit and vegetable is getting larger and larger, and the force of the pressure adjusting mechanism 40 is also getting larger and larger, that is, the second cushioning member 405 and the bottom cover 402 are subjected to the upward pressing force. The larger the pressing force overcomes the first frictional force f1 and the second frictional force f2, the second rotating member 405 is forced to rotate relative to the first rotating member 404 and moved upward, and at the same time, the rotating member 401 When the rotation is performed, the bottom cover 402 is also moved upward, and the straight stop beam 3 is raised to the top position thereof (that is, when the hinge plate 93 is in the upright state). At this time, the movable member such as the movable beam 3, the guide plate 87 or the upper top plate 91 is movable. Any one of them will encounter the stroke switch, so that the stroke switch action will drive the motor 81 to stop and stop, indicating that the juice has been completed under the adjusted pressure. Obviously, during this pressing process, the pressure regulating mechanism 40 functions both as a buffer, and at the same time, when the second rotating member 405 starts to rotate and the bottom cover 402 is moved up, the bottom cover 402 and the moving beam 3 are The height of the space within the pressure chamber 32 begins to remain constant, which determines the thickness of the final juiced fruit and vegetable. That is, the maximum pressure that the fruit and vegetable are subjected to is the pressure at which the first frictional force f1 and the second frictional force f2 are overcome, and the maximum pressure can be adjusted by adjusting the up and down movement of the rotation preventing member 401. Thus the present embodiment can be adapted to the juice extraction needs of different fruits and vegetables.

During this process, due to the existence of the helicoidal surface, the force for rotating the second rotating member 405 and the rotation preventing member 401 is already a component of the upward pressing force of the moving beam, and is also easily passed through the rotation preventing member 401 and the damper seat. The cooperation of 408 is stopped.

Moreover, in order to flexibly rotate the second rotating member 405, a bearing 403 is disposed between the bottom cover 402 and the second rotating member 405. Moreover, in order to prevent the bottom cover 402 from rotating together with the second rotating member 405, the lower surface of the upper beam 4 is provided with a guide rail 406 downwardly. The guide rail 406 is coupled with the bottom cover 402 so that the bottom cover 402 can only move up and down. Rotate. At the same time, in order to enable the rotation of the rotation preventing member 401 and the second rotating member 405 after pressing, a return spring 409 is disposed between the second rotating member 405 and the supporting sleeve 406a.
