Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a quantitative feeding device for a juicer. Background Technology

[0002] A juicer is a kitchen appliance that can separate the juice from fruits, vegetables, and other ingredients to make pure fruit or vegetable juice. There are two main working principles: one is to use a motor to drive the built-in rotating blades to chop the fruits or vegetables placed in the juicing cup at high speed. Then, through centrifugal force, the juice is thrown to the edge of the juicing cup, filtered through a filter, and flows into the juice collection container, while the residue is left inside the filter. The other is to use a screw or similar mechanical device to squeeze the fruits and vegetables to extract the juice, while the residue is discharged from the pulp outlet. This method can extract the juice more fully and better retain the nutrients in the fruits and vegetables.

[0003] Nowadays, with the popularization of healthy eating concepts, more and more people tend to juice a variety of fruits and vegetables to obtain richer nutrition. However, in practice, users often rely on their intuition to control the proportion of various ingredients. This method has obvious limitations, especially for high-sugar fruits (such as mangoes and grapes). The lack of precise control can easily lead to excessive amounts, resulting in excessively high sugar content in the juice, which is not good for the health of the drinker. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative feeding device for a juicer. By incorporating a weighable support plate into the feeding device, the problem of operators finding it inconvenient to control the ratio of fruits and vegetables during the use of existing juicers is solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a quantitative feeding device for a juicer, including a feeding cylinder, two hollow rods rotatably fitted inside the feeding cylinder, a frustum mounting sleeve fixedly connected between the two hollow rods, a weighing sensor fixedly installed inside the frustum mounting sleeve, and a bearing plate fixedly installed on the top of the weighing sensor.

[0007] The present invention is further configured such that an annular groove is provided on the inner circumferential side of the truncated cone mounting sleeve, and a sealing ring is embedded in the annular groove.

[0008] The present invention is further configured such that a control box is fixedly installed on the periphery of the feed cylinder, a sleeve is fixedly installed on the inner wall of the control box, and a sleeve rod is slidably fitted on the outer periphery of one of the hollow rods near the control box, and the sleeve rod is slidably fitted through the control box.

[0009] The present invention is further configured such that two symmetrical connecting keys are fixedly connected to the outer peripheral side of the hollow rod near the control box, and two symmetrical sliding grooves are opened on the inner peripheral side of the sleeve rod, and the connecting keys slide in cooperation with the sliding grooves.

[0010] The present invention is further configured such that a spring located inside the sleeve is sleeved on the outer periphery of the sleeve rod, a connecting ring is fixedly connected to one end of the sleeve rod, and two symmetrical limiting keys are fixedly connected to the periphery of the connecting ring.

[0011] The present invention is further configured such that two sets of symmetrical limiting grooves are provided on the inner wall of the sleeve, and the limiting grooves slide in cooperation with the limiting keys.

[0012] The present invention is further configured such that a display screen is fixedly installed on the outer wall of the control box, and the display screen is electrically connected to the weighing sensor.

[0013] This utility model has the following beneficial effects:

[0014] This invention involves feeding vegetables or fruits into a feeding cylinder, causing them to fall onto a support plate. This triggers a weighing sensor below the support plate to emit an electrical signal, which is transmitted to a display screen. The screen then shows the weight of the fruits or vegetables on the support plate. A lever controls the rotation of the support plate, causing the fruits or vegetables to fall into the juicing cup below. The support plate covers the juicing cup, preventing juice from splashing out during the juicing process. This allows for precise control of the amount of vegetables and fruits used, meeting the needs of a healthy lifestyle.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0027] Please see Figure 1-6 This utility model is a quantitative feeding device for a juicer, including a feeding cylinder 1, two hollow rods 2 rotatably fitted inside the feeding cylinder 1, a frustum mounting sleeve 3 fixedly connected between the two hollow rods 2, a weighing sensor 4 fixedly installed inside the frustum mounting sleeve 3, a support plate 5 fixedly installed on the top of the weighing sensor 4, a control box 8 fixedly installed on the side of the feeding cylinder 1, and a display screen 17 fixedly installed on the outer wall of the control box 8. The display screen 17 is electrically connected to the weighing sensor 4. In use, the device is installed above the juicing cup, and fruits or vegetables are put into the top feeding port of the feeding cylinder 1, causing the fruits or vegetables to fall onto the support plate 5. This causes a change in the pressure applied to the weighing sensor 4 by the support plate 5. At this time, the resistance of the strain gauge in the weighing sensor 4 changes, and the weighing sensor 4 outputs an electrical signal, which is displayed on the display screen 17 via the circuit board, showing the weight of the fruits or vegetables on the support plate 5.

[0028] Specifically, an annular groove 6 is provided on the inner circumferential side of the frustum mounting sleeve 3, and a sealing ring 7 is embedded in the annular groove 6. In this way, when the load cell 4 is installed inside the frustum mounting sleeve 3, the sealing ring 7 will be fitted on the outer wall of the load cell 4, preventing juice from entering the frustum mounting sleeve 3 through the gap between the load cell 4 and the frustum mounting sleeve 3, so as to corrode the circuit of the load cell 4.

[0029] Furthermore, a sleeve 9 is fixedly installed on the inner wall of the control box 8, and a sleeve rod 10 is slidably fitted on the outer side of a hollow rod 2 near the control box 8. The sleeve rod 10 is slidably fitted through the control box 8. Two symmetrical connecting keys 11 are fixedly connected to the outer side of the hollow rod 2 near the control box 8. Two symmetrical sliding grooves 12 are opened on the inner side of the sleeve rod 10. The connecting keys 11 are slidably fitted with the sliding grooves 12. In this way, the sleeve rod 10 can slide relative to the hollow rod 2 without rotating relative to the hollow rod 2.

[0030] A spring 13 is fitted onto the outer periphery of the sleeve rod 10 and located inside the sleeve 9. A connecting ring 14 is fixedly connected to one end of the sleeve rod 10, and two symmetrical limiting keys 15 are fixedly connected to the periphery of the connecting ring 14. Two sets of symmetrical limiting grooves 16 are formed on the inner wall of the sleeve 9. The limiting grooves 16 and the limiting keys 15 are slidably engaged. By inserting the limiting keys 15 into the limiting grooves 16, the rotation of the sleeve rod 10 is restricted. When the fruit or vegetables on the bearing plate 5 reach a suitable weight, the sleeve rod 10 is pulled outward, causing the two limiting keys 15 on the periphery of the connecting ring 14 to disengage from the two limiting grooves 16 on the inner wall of the sleeve 9. Then, the sleeve rod 10 is rotated. 10 drives a hollow rod 2 to rotate, which in turn drives the frustum mounting sleeve 3 to rotate. The frustum mounting sleeve 3 drives the support plate 5 to rotate through the weighing sensor 4 inside it, causing the fruits or vegetables on the support plate 5 to fall into the juicing cup below. Then the support plate 5 is completely rotated 180 degrees to prevent juice from splashing out of the juicing cup during the juicing process. At the same time, it can also prevent juice from remaining on the frustum mounting sleeve 3 and the weighing sensor 4. When the sleeve rod 10 is rotated, the limit key 15 can be inserted into the limit groove 16 by pushing the sleeve rod 10 in the opposite direction, thereby limiting the rotation of the sleeve rod 10 and thus limiting the rotation of the support plate 5.

[0031] The operation process of this embodiment is as follows: When using this device, first install the device on the juicing cup, then put vegetables or fruits into the feeding cylinder 1, so that the fruits or vegetables fall onto the support plate 5. The weighing sensor 4 under the support plate 5 outputs an electrical signal to the display screen 17 to display the weight of the fruits or vegetables on the support plate 5. When the displayed weight reaches the target, pull the sleeve rod 10 outward to make the two limit keys 15 disengage from the corresponding two limit grooves 16. Then rotate the sleeve rod 10 so that the sleeve rod 10 drives the frustum mounting sleeve 3 to rotate through a hollow rod 2. The frustum mounting sleeve 3 then drives the support plate 5 to rotate through the weighing sensor 4, so that the fruits or vegetables on the support plate 5 fall into the juicing cup below. Then, the sleeve rod 10 drives the support plate 5 to rotate completely 180 degrees so that the support plate 5 covers the juicing cup. At the same time, push the sleeve rod 10 in the opposite direction so that the limit keys 15 are inserted into the limit grooves 16, thereby limiting the rotation of the support plate 5.
