Description

[Technical field]

[0001] The utility model relates to a juice extractor, belonging to the field of juice extractors. [Background technology]

[0002] As more and more people use juicers, their safety issues have also attracted attention. Usually, juicers are equipped with a squeeze rod or blade. If a child accidentally puts his hand into the feed port when the juicer is working, he may be injured. Therefore, mainstream juicer products on the market are equipped with a safety device that can detect the opening and closing status of the juicer's top cover. The juicer can only work when the top cover is closed. When the top cover is opened, the juicer stops working.

[0003] Although this design solves the safety issue of large-caliber juicers, it also causes the juicer to stop working whenever the user adds ingredients. The customer needs to frequently turn on the juicer, which makes the operation very cumbersome. Especially when putting in some small-sized ingredients, this shutdown mode seems redundant. For example, when squeezing some mixed juices, you may need to put in ingredients of different sizes. Frequent shutdown operations will obviously affect the juicing efficiency. [Contents of the utility model]

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a juicer which has a higher juicing efficiency for juicing food materials of various sizes while ensuring safety.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A juicer comprises a main body, a feed shell and a safety device, wherein the feed shell comprises a main shell and a cover assembly arranged on the top of the main shell, the main shell is provided with a first feed port, the cover assembly comprises a main cover, and the main cover is installed on the first feed port, the safety device is configured so that when the main cover is in a closed state, the main body can work, and when the main cover is in an open state, the safety device triggers the main body to stop working, the main cover is provided with a second feed port, a secondary cover is rotatably arranged at the second feed port, the secondary cover is provided with a accommodating cavity for placing relatively small food materials, and when the secondary cover is flipped, the food materials in the accommodating cavity are sent into the main shell.

[0007] The beneficial effects of adopting the utility model are:

[0008] Firstly, since the first feed port and the second feed port are provided in the utility model, the user has more choices when feeding. Large-sized ingredients can be fed in through the first feed port, while relatively small-sized objects can be fed in through the second feed port, which is suitable for more ingredients. At the same time, it also solves the shortcoming that mainstream juicers on the market cannot accommodate large-sized ingredients while ensuring safety.

[0009] In addition, the key is that the utility model has high practicality while ensuring safety. Relatively small food materials can be continuously fed in through the second feed port without stopping work. With such a structural design, large food materials can be put in first, and relatively small food materials can be continuously put in without stopping the machine, thereby achieving the effect of mixed juice, reducing downtime when processing mixed juice, making operation more coherent, achieving continuous work, improving juicing efficiency, and enhancing user experience.

[0010] Finally, since the shutdown operation is reduced when processing mixed juice, the motor inside the juicer will also reduce the impact caused by frequent shutdowns due to this design, especially when the juicer is squeezing large-sized ingredients. If it stops halfway, it is easy to get stuck when starting again. Therefore, the continuous working mode of the utility model can appropriately extend the life of the motor.

[0042] Embodiment 1:

[0043] Figures 1 to 6 What is shown is the first embodiment of the utility model. As shown in the figure, this embodiment includes a main body 3, a feed shell 1 and a safety device 22. The feed shell 1 includes a main shell 11 and a cover assembly arranged on the top of the main shell 11. The main shell 11 is preferably cylindrical and used to accommodate large-sized food materials. A first feed port 111 is provided on the top of the main shell 11. The diameter of the first feed port 111 is substantially the same as the diameter of the main shell 11. The cover assembly includes a main cover 12. This embodiment is also provided with a safety device 22. The safety device 2 is configured so that when the main cover 12 is in a closed state, the main body 3 can work, and when the main cover 12 is in an open state, the safety device 22 is triggered to control the main body 3 to stop working. The work of the main body referred to here mainly refers to the rotation of the extrusion screw driven by the motor of the main body. Such a design can prevent people from reaching in when the juicer is working, thereby improving safety.

[0044] Figures 2 to 4 FIG. 1 is a partial schematic diagram of the feed housing of this embodiment. In this embodiment, a second feed port 121 is provided in the middle of the main cover 12. Figure 3As shown, in this embodiment, the projection area S2 of the second feed port 121 is preferably set to be smaller than the projection area S1 of the first feed port 111, so as to allow some smaller-sized ingredients to be put in without interrupting the operation of the juicer. This allows the user to continue adding ingredients without having to repeatedly open the juicer, thereby improving the user experience.

[0045] In this embodiment, a secondary cover body 13 is provided at the second feed port 121. The secondary cover body 13 is provided with a receiving cavity for placing food. The receiving cavity is used to temporarily store some relatively small food. In addition, when the user needs to put in several food at one time, they can first put them in the receiving cavity and then flip them all at once, saving the flipping operation time.

[0046] In order to further improve safety, for example, to prevent children's hands from reaching into the second feed port 121, the covering projection shape of the secondary cover body 13 is preferably adapted to the cross-sectional shape of the second feed port 121. This design is intended to minimize the gap between the secondary cover body 13 and the second feed port 121 as much as possible, which can not only prevent the user's hands from reaching into the gap, but also prevent food from getting stuck in the gap. The secondary cover body 13 is preferably rotatably connected to the main cover body 12 via a first rotating shaft 16. The first rotating shaft 16 is preferably located in the middle of the second feed port 121, dividing the second feed port 121 into two areas, so that the second feed port 121 is further divided, further reducing the diameter of the second feed port 121. In this embodiment, the axial line H1 of the first rotating shaft 16 preferably divides the second feed port 121 into two areas of equal area (such as Figure 3 As shown), in other embodiments, the axial line of the first rotating shaft 16 can also be used to divide the second feed port 121 into two areas of different areas, whether the area is the same or different, wherein the projection area of ​​the larger area is smaller than the projection area of ​​the first feed port 111, and the same can be referred to. Figure 3 It is equivalent to dividing the projection area of ​​S2 into half, and the area of ​​this half is smaller than S1.

[0047] In addition, when the secondary cover 13 in this embodiment is in a horizontal state, the accommodating cavity forms a concave surface downwards. This design is very clever. Figure 2 As shown, after the accommodating chamber is flipped 90 degrees, the concave accommodating chamber further deepens the distance between it and the left side wall of the second feed port 121, which can make the unloading space larger. Since the upper outer ring part of the accommodating chamber is still on the axial line of the first rotating shaft 16, it does not affect the safety. At the same time, after flipping 90 degrees, the distance between the accommodating chamber and the right side wall of the second feed port 121 becomes smaller, so that the protection effect of this area is improved. Therefore, the design of the accommodating chamber, when flipping the feeding, makes the space required for feeding be increased, while the space not required for feeding is reduced.

[0048] This embodiment is preferably provided with a safety device, the safety device 2 comprising a trigger member 21 disposed on the main cover 12 and a trigger mechanism 22 disposed on the main housing 11 for cooperating with the trigger member 21, the trigger mechanism 22 being used to be connected to the main body 1 to control the operation of the main body 1, and the trigger mechanism 22 comprising a movable member movably connected to the main housing 1. Figure 6 As shown, in this embodiment, the trigger member 21 is preferably a protrusion, and the trigger mechanism 22 is a sliding rod slidably set on the main shell 11 or the handle 14. The trigger mechanism 22 is connected to the main body 3 to control the working state of the main body 3. When the main cover 12 is closed, the trigger member 21 and the trigger mechanism 22 are in contact, and the main body 3 works. When the main cover 12 is opened, the trigger member 21 and the trigger mechanism 22 are separated, and the main body 3 stops working. This design can stop the product from working when the cover is opened, prevent the user from accidentally putting his hand into the main shell 11 and getting injured, and improve the safety of the product.

[0049] It should be noted that this embodiment only illustrates one implementation method of the movable component. At the same time, in other embodiments, the trigger component is not limited to this mechanical activity mode, and can also be a micro switch arranged on the main shell 11. The micro switch is electrically connected to the control circuit of the main body. When the protrusion abuts against the micro switch, an electrical signal is triggered. Alternatively, the trigger mechanism can be a sensor arranged on the main shell, such as an infrared sensor, a photosensitive sensor, a Hall sensor, etc. These sensors will also generate corresponding electrical signals when they come into contact with the trigger member.

[0050] The main cover body 12 and the main shell body 11 are preferably rotatably connected via a second rotating shaft 17, and the second rotating shaft 17 is arranged on one side of the main shell body 11. The trigger member 21 and the trigger mechanism 22 are respectively arranged on the main cover body 12 and the main shell body 11 on the side opposite to the second rotating shaft 17. Such a design not only facilitates the opening and closing of the main cover body 12, but also plays a limiting role, so that the trigger member 21 and the trigger mechanism 22 can definitely contact when the main cover body 12 is closed, thereby simplifying the operation.

[0051] It should be noted that the main cover 12 of this embodiment is preferably connected by the second shaft 17, which is a detachable and rotatable connection. In other embodiments, the second shaft may not be provided, and the main cover can be completely separated from the main housing. Accordingly, in these embodiments, a foolproof device should be provided to ensure that when the main cover is closed, the position of the trigger member and the trigger mechanism can correspond to each other, so as to ensure the normal operation of the juicer. These implementations all fall within the protection scope of the present utility model.

[0052] like Figure 4As shown, the main housing 11 is preferably provided with a handle 14 for holding, the handle 14 is provided on the side opposite to the second rotating shaft 17, the trigger mechanism 22 is provided on one side of the handle 14, the main cover 12 is provided with a lug 15 on the side opposite to the second rotating shaft 17, the trigger member 21 is provided at the bottom of the lug 15, when the main cover 12 is closed, the trigger member 21 abuts against the trigger mechanism 22, that is, the lug abuts against the sliding rod. Such a design is not only convenient for users to hold, but also provides installation space for the safety device 22, making the safety device 22 more concealed and the product more beautiful.

[0053] The lug 15 is preferably provided with a cover opening device 151. When the main cover 12 is closed, the cover opening device 151 is buckled on the handle 14. When opening the cover, the user only needs to turn the cover opening device 151 to open the main cover 12. Since the juicer inevitably vibrates during operation, the main cover 12 may be loosened, causing the safety device 22 to be triggered, causing the juicer to stop working. This design can improve the stability of the main cover 12 when it is closed. At the same time, the handle 14, the safety device 22, and the cover opening device 151 are all arranged in one place, which is convenient for designing the safety device and the cover opening device at the structural position where the handle is located, which is convenient for structural design, making the product more concise and beautiful, and allowing the user to complete the operation of holding and opening the cover with only one hand, making the operation more convenient.

[0054] Of course, in other embodiments, the handle, the safety device, and the cover opening device may be provided separately instead of being provided at the same place. These implementations all fall within the protection scope of the present utility model.

[0055] In this embodiment, a limiting device for maintaining the initial position is preferably provided on the secondary cover 13. In the initial position, the secondary cover 13 covers the second feed port 121 shown. Furthermore, in this embodiment, the limiting device is preferably a limiting baffle 132 provided on the secondary cover 13. The limiting baffle 132 allows the secondary cover 13 to be placed on the main cover 12, which is convenient for placing food inward. At the same time, the user can flip the secondary cover 13 by turning the limiting baffle 132, which can prevent the hand from touching the food, which is more hygienic and healthy. The main cover 12 is also preferably provided with a limiting recess 122 that cooperates with the limiting baffle 132. When the limiting baffle 132 enters the limiting recess 122, the secondary cover 13 and the main cover 12 tend to be flush. This design can prevent the secondary cover 13 from being more stable, reduce the probability of food falling due to instability, and reduce waste.

[0056] like Figure 6As shown, an extrusion screw (not shown in the figure) for extruding food is provided in the main shell body, and the axial direction of the second feed port 121 is preferably coaxial with the axial direction of the extrusion screw, both of which are axis H2. The purpose of this design is to keep the food entering from the first feed port 121 relatively in a better feeding position. Usually, the first feed port and the extrusion screw have set structures and orientations, and usually the feeding position from the first feed port is a better feeding position. In this embodiment, the axial direction of the second feed port 121 is preferably coaxial with the axial direction of the extrusion screw, so that the feeding position of the second feed port 121 can be in a better position without changing the original structure.

[0057] It should be noted that, in other embodiments, the axis of the second feed port 121 and the axis of the first feed port 111 do not need to be completely coaxial, and there may be a certain spacing deviation. In the case of a spacing deviation, the horizontal spacing is preferably ≤8mm. If the spacing is too large, the food will not fall into the appropriate feeding position, thereby affecting the work of the extrusion screw, and even an inappropriate feeding position will cause the extrusion screw to not work normally.

[0058] In addition, in this embodiment, in order to further improve the feeding convenience of small-sized food, a third feeding hole 131 is preferably provided in the middle of the secondary cover 13 of this embodiment, and the size of the third feeding port 131 is L3, and the L3 preferably satisfies: L3≤43.5mm, and the diameter of the third feeding port 131 is smaller than the diameter of the second feeding port 121. When the user continuously adds some very small-sized food, they can directly put them in through the third feeding port 131, eliminating the step of rotating the secondary cover 13 several times, making the operation more convenient, and the small size of L3 can prevent the user from putting his hand in, further improving safety.

[0059] like Figure 6 As shown, the position setting of the third feed port 131 in this embodiment is also similar to the second feed port 121, that is, the axial direction of the third feed port 131 is coaxial with the axial direction of the first feed port 111, both of which are axis H2; or, the horizontal distance between the axis of the third feed port 131 and the axis of the first feed port 111 is ≤8mm.

[0060] In the present embodiment, the main shell 11 is a circular rotating body, and the corresponding extrusion screw belongs to the central axis feeding method. Therefore, the axial direction of the first feed port 111, the second feed port 121, and the third feed port 131 in the present embodiment is coaxial with the rotation axis of the main shell 11. This design is also to allow the food entering from the second feed port 121 or the third feed port 131 to fall directly on the better feeding position on the extrusion screw, so as to quickly squeeze the juice and improve work efficiency. For the size of the first feed port 111 and the second feed port 121 in the present embodiment, it is preferably set as follows: the maximum size L1 of the first feed port satisfies: 100mm≤L1≤200mm. The function of the first feed port 111 is usually to put in large-sized food, so its caliber cannot be too small, otherwise it will not match its function. Of course, its size cannot be too large. If the size is too large, it will not only increase the product volume, but also affect the setting of the second feed port 121, and the overall proportion will be uncoordinated.

[0061] Similarly, for the size of the second feed port 121, it is preferred that the maximum size L2 of the second feed port satisfies: 60mm≤L2≤130mm. The main function of the second feed port 121 is to put in smaller or medium-sized food materials, and at the same time, it must meet certain safety requirements. Therefore, its size cannot be too large, and at the same time, its size should not be too small. This reserves a certain amount of selection space for the setting of the third feed port 131.

[0062] It should be noted that the maximum size of the first feed port 111 or the maximum size of the second feed port 121 is the length of a line segment that passes through the center point of the first feed port 111 or the second feed port 121 and whose two ends fall on the edge of the first feed port 111 or the second feed port 121, such as Figure 3 As shown, in this embodiment, since the first feed inlet 111 and the second feed inlet 121 are both circular, L1 and L2 are the diameters of the circles. In other embodiments, if the first feed inlet or the second feed inlet is elliptical, the maximum dimension is the line segment passing through the two foci of the ellipse. If the first feed inlet or the second feed inlet is rectangular, the maximum dimension is the diagonal. All these implementations fall within the protection scope of the present utility model.

[0063] In order to make the positioning division of the first feed port 111 and the second feed port 121 clearer, the maximum size L1 of the first feed port 111 and the maximum size L2 of the second feed port 121 meet the following conditions: 0.5≤L2 / L1≤0.95. This design is to make the positioning of the first feed port 111 and the second feed port 121 more accurate and clear. If the ratio of L2 / L1 is too close or the same, or even exceeds 1, the size of the second feed port 121 will be too large and its safety protection function will be weakened, so there needs to be a difference. If the ratio of L2 / L1 is too small, the second feed port 121 will not be able to put in some relatively medium-sized food. At the same time, since the third feed port 131 is also separately provided in this embodiment, the size of the second feed port 121 is appropriately enlarged, and it is more appropriate to define it in a range of ≥0.5. Therefore, L2 / L1 in this embodiment is preferably 0.8, which is more suitable in terms of the coordination of the whole machine and the accuracy of feeding. On the whole, the ratio setting of the first feed port 111 and the second feed port 121 of the present embodiment allows the first feed port 111, the second feed port 121, and the third feed port 131 to be divided into three levels of large, medium, and small, corresponding to ingredients of different sizes, with a more precise and clear division of labor, and no duplication of functions between them, so that users can have a clearer understanding of the adding method when adding ingredients, and are guided to use the second feed port 121 and the third feed port 131 more often. When adding medium and small sized ingredients, there is no need to open the main cover body 12, which reduces the situation of putting hands into the main shell body 11, thereby improving safety.

[0064] Embodiment 2:

[0065] Different from the first embodiment, the projection area S2 of the second feed port 121 is larger than the projection area S1 of the first feed port 111, and the secondary cover body 13 is rotatably connected to the main cover body 12 via a first rotating shaft 16. The axial line of the first rotating shaft 16 divides the second feed port 121 into two areas, and the projection area of ​​the relatively larger area of ​​the two areas is smaller than the projection area of ​​the first feed port 111.

Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation.
