Description

Technical Field

[0001] The utility model relates to the technical field of food processing devices, in particular to a feeding structure of a slow squeezer. Background Art

[0002] As people's living standards improve, they pay more and more attention to their health and diet, and their requirements for the nutrition and taste of fruit and vegetable juice drinks are gradually increasing. The structure of juicers on the market generally includes a feed chamber, a working part and a filter structure. The working part can be divided into a screw extrusion type and a centrifugal type. After the ingredients are put into the feed chamber, the working part crushes the ingredients and then cooperates with the filter structure to separate the juice and residue to obtain fruit and vegetable juice. According to national standards, in order to protect the safety of users, the feed diameter of the squeeze juicer shall not be greater than 45mm. This diameter standard requires that most fruits need to be cut into small pieces before they can be put into the feed port when juicing, which brings great inconvenience to consumers.

[0003] Chinese patent CN204995171U discloses a machine base with a motor, a pressing chamber mounted on the machine base, and a screw arranged in the pressing chamber, wherein the pressing chamber includes a chamber body and a feed channel, wherein the feed channel is provided with an upper port and a lower port, wherein the lower port is connected to the chamber body, wherein the upper port is provided with a reversible storage platform, wherein the edge of the upper port is provided with a retaining rib for reducing the area of ​​the upper port. The reversing axis of the storage platform crosses the upper port, and the retaining rib is provided on the side of the edge of the upper port opposite to the reversing axis of the storage platform.

[0004] In the existing method of using the storage table as a safety barrier for the feeding channel, the storage table needs to be turned 180 degrees to allow the food to fall into the feeding channel, the feeding speed is slow, the juicing efficiency is affected, and the user experience is poor. Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0005] The utility model aims to provide a slow press feeding structure with reasonable structure, fast feeding and convenient operation in view of the defects and shortcomings of the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model discloses a slow juicer feeding structure, comprising a juice extractor body, a feed pipe is provided on the juice extractor body, a first funnel and a second funnel are provided on the upper port of the feed pipe, the first end of the first funnel and the first end of the second funnel are rotatably connected to the feed pipe through a first hinge, and the first funnel is transmission-connected to the second funnel through the first hinge; the second end of the first funnel and the second end of the second funnel are rotatably connected to the feed pipe through a second hinge. The juice extractor body is composed of a juice extractor barrel, an extrusion screw, a filter, a slag discharge nozzle and a juice outlet, the feed pipe is provided on the juice extractor barrel, the lower end of the feed pipe is connected to the inner cavity of the juice extractor barrel, the food is put into the juice extractor barrel from the upper port of the feed pipe, and after being ground and crushed by the extrusion screw and filtered by the filter, the juice flows out from the juice outlet, and the residue is discharged from the slag discharge nozzle.

[0008] The first funnel and the second funnel form a hemispherical structure and cover the upper end of the feed tube to prevent the user's hand from entering through the feed tube and causing risks. Of course, there is a gap between the first funnel and the second funnel, and small pieces of food can be directly put into the feed tube through the gap between the two. Large pieces of food are first placed on the cover structure formed by the first funnel and the second funnel. By turning the first funnel to drive the second funnel to rotate synchronously, the gap between the two becomes larger, so that the food falls into the feed tube by itself under the action of gravity, and then enters the juicer to squeeze out juice.

[0009] Furthermore, the first funnel and the second funnel are rotatably connected to the feed pipe respectively, and the first funnel can be turned upward, and drive the second funnel to rotate synchronously, so that the above-mentioned gap becomes larger so that large pieces of food fall into the feed pipe. It can be understood that the maximum turning angle of the first funnel and the second funnel is 90°, so as to facilitate the user's operation and improve the feeding speed and juice extraction efficiency.

[0010] According to the above scheme, the first hinge includes a transmission box, a meniscus and a passive gear. The transmission box is fixedly arranged on one side of the upper port of the feed pipe, and a first positioning column is arranged on the inner side wall of the transmission box; an arc-shaped slide is arranged at the bottom of the transmission box, and the meniscus can be slidably arranged on the arc-shaped slide, and the first end of the first funnel is fixedly connected to the meniscus; the first end of the second funnel is rotatably connected to the first positioning column, and the passive gear is fixedly arranged on the first end of the second funnel, and the meniscus is transmission-connected to the passive gear through meshing teeth. The transmission box is an open structure, and the opening of the transmission box faces the first funnel and the second funnel. In particular, the bottom inner wall of the transmission box forms an arc-shaped slide, and the lower outer edge of the meniscus is also an arc-shaped structure. The arc-shaped slide of the transmission box serves as a basis to support the meniscus and the first end of the first funnel, and the meniscus can slide along the arc-shaped slide, so that the first end of the first funnel can rotate on the transmission box. It is understandable that the first end of the first funnel needs to be connected to the meniscus via a transition structure so that its flipping center axis coincides with the center of the arc-shaped slideway and the meniscus.

[0011] Furthermore, the first positioning column is arranged above the meniscus and is fixedly connected to the inner wall of the transmission box, and the second funnel can rotate around the first positioning column. It can be understood that the second funnel, the first positioning column, the first funnel, the meniscus and the arc slide are all arranged around the same rotation center axis. For this purpose, a notch needs to be opened on the transition structure on the first funnel to allow the second end of the second funnel to pass through and be rotatably connected to the first positioning column.

[0012] The upper outer edge of the meniscus is provided with meshing teeth, and meshes with the passive gear through the meshing teeth. When the first funnel is flipped, it can drive the second funnel to rotate synchronously, and open the gap between the two to the maximum extent. In particular, this arrangement allows the first funnel to only flip no more than 90° to allow large pieces of food to fall into the feed port through the gap.

[0013] According to the above scheme, the first hinge also includes a planetary gear, a second positioning column is provided on the inner side wall of the transmission box, and the second positioning column is provided between the first positioning column and the meniscus; the planetary gear is rotatably provided on the second positioning column, and the meniscus, the planetary gear and the driven gear are meshed and connected in sequence. Preferably, a planetary gear is provided between the meniscus and the driven gear to transmit, so that the first funnel and the second funnel rotate in opposite directions on the feeding pipe, that is, the two move toward each other or move away from each other synchronously. In particular, the planetary gear can play a role in amplifying and reducing the transmission ratio.

[0014] According to the above scheme, a plate buckle is provided on the outer side of the first funnel, and the rotation angle range of the first funnel is between 0°-45°, and the corresponding rotation angle range of the second funnel is between 0°-90°. As above, the meniscus is connected to the passive gear through a planetary gear transmission, so that the transmission ratio between the meniscus and the passive gear is greater than 1, and the preferred transmission ratio between the meniscus and the passive gear is 1:3, that is, the first funnel rotates 30° to drive the second funnel to rotate 90°, and the gap between the two is maximized, so that food can fall directly into the feeding tube.

[0015] According to the above scheme, the second hinge includes an axle seat and a coaxial shaft, the axle seat is fixedly arranged on the other side of the upper port of the feed pipe, and the coaxial shaft is arranged on the second end of the first funnel; a concentric shaft sleeve is arranged on the second end of the second funnel, and the two ends of the concentric shaft are respectively inserted into the axle seat and the concentric shaft sleeve. The second hinge is used to coaxially arrange the first funnel and the second funnel on the feed pipe, and the concentric shaft is respectively connected to the axle seat and the concentric shaft sleeve, so that the second ends of the first funnel and the second funnel are respectively rotatably connected to the axle seat, thereby realizing concentric rotation.

[0016] According to the above scheme, a sleeve is provided on the upper end of the feed pipe, and a transmission box and a shaft seat are respectively provided on both sides of the upper end of the sleeve. The sleeve is used to set the transmission box and the shaft seat to install the first hinge, the second hinge, the first funnel and the second funnel. The existing feed barrel and the juicer barrel of the juicer body are an integrally formed structure, and a detachable buckle structure is provided on the sleeve, so that it can be installed on the upper end of the feed barrel, thereby improving the existing product structure and reducing the difficulty of production.

[0017] According to the above scheme, the first funnel and the second funnel are paired with each other to form a storage cavity on the upper end of the feed tube, and a feeding port is provided between the first funnel and the second funnel, and the storage cavity is connected to the feed tube through the feeding port; the utility model also includes a pressing rod, and the pressing rod can pass through the feeding port to be inserted into the feed tube. The first funnel and the second funnel are paired to form a structure similar to a hemisphere, so that the storage cavity is bowl-shaped, and in particular, there is a gap between the first funnel and the second funnel to form a feeding port, and the feeding port is the above-mentioned notch, which allows small pieces of food to fall directly, but still prevents human hands from entering the feed tube. After the food is put into the feed tube, the first funnel and the second funnel are in a closed state, and the passable area of ​​the feeding port is the smallest at this time. The pressing rod can pass through the feeding port into the feed tube to push the food into the juicing chamber.

[0018] According to the above solution, the first funnel and the second funnel are both provided with a support plate, the support plate is inserted into the material drop opening, and both sides of the pressure rod are provided with a slide groove that can accommodate the support plate to pass through. Since the material drop opening is set between the first funnel and the second funnel, in order to better protect the entry of human hands, the support plate is set on the first funnel and the second funnel to limit the passability of the material drop opening. Of course, the support plate also forms the bottom support of the storage cavity.

[0019] The utility model discloses a feeding structure of a slow juicer, wherein a first funnel and a second funnel are arranged at an upper end of a feed pipe to prevent a user's hand from entering the feed pipe, a gap is provided between the first funnel and the second funnel, small pieces of food can be directly put into the feed pipe from the gap between the two, and large pieces of food can be placed on the first funnel and the second funnel, the first funnel and the second funnel are rotatably connected to the feed pipe respectively, the first funnel can be turned upwards, and drive the second funnel to rotate synchronously, so that the above-mentioned gap becomes larger so that large pieces of food can fall into the feed pipe, the turning angle of the first funnel and the second funnel is 90° at most, thereby facilitating the user's operation and improving the feeding speed and juicing efficiency.

[0027] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1 As shown, a slow squeezer feeding structure described in the utility model comprises a juice extracting body 1, a feed pipe 11 is provided on the juice extracting body 1, a first funnel 2 and a second funnel 3 are provided on the upper end of the feed pipe 11, the first end of the first funnel 2 and the first end of the second funnel 3 are rotatably connected to the feed pipe 11 through a first hinge, and the first funnel 2 is transmission-connected to the second funnel 3 through the first hinge; the second end of the first funnel 2 and the second end of the second funnel 3 are rotatably connected to the feed pipe 11 through a second hinge. The juice extracting body 1 is composed of a juice extracting barrel 12, an extrusion screw 13, a filter 14, a slag discharge nozzle 15 and a juice outlet 16. The feed pipe 11 is provided on the juice extracting barrel 12, and the lower end of the feed pipe 11 is connected to the inner cavity of the juice extracting barrel 12. After the food is put into the juice extracting barrel 12 from the upper end of the feed pipe 11, it is ground and crushed by the extrusion screw 13 and filtered by the filter 14, and the juice flows out from the juice outlet 16, and the residue is discharged from the slag discharge nozzle 15.

[0029] The first funnel 2 and the second funnel 3 form a hemispherical structure and cover the upper end of the feed tube 11 to prevent the user's hand from entering the feed tube 11 and causing risks. Of course, there is a gap between the first funnel 2 and the second funnel 3, which is not completely closed. Small pieces of food can be directly put into the feed tube 11 through the gap between the two. Large pieces of food are first placed on the cover structure formed by the first funnel 2 and the second funnel 3. By turning the first funnel 2 to drive the second funnel 3 to rotate synchronously, the gap between the two becomes larger, so that the food falls into the feed tube 11 by itself under the action of gravity, and then enters the juicer 12 to squeeze out juice.

[0030] Furthermore, the first funnel 2 and the second funnel 3 are rotatably connected to the feed pipe 11, respectively, and the first funnel 2 can be turned upward, and drive the second funnel 3 to rotate synchronously, so that the above-mentioned gap becomes larger so that large pieces of food fall into the feed pipe 11. It can be understood that the maximum turning angle of the first funnel 2 and the second funnel 3 is 90°, so as to facilitate the user's operation and improve the feeding speed and juice extraction efficiency.

[0031] The first hinge includes a transmission box 41, a meniscus 21 and a passive gear 31. The transmission box 41 is fixedly arranged on one side of the upper end of the feed pipe 11, and a first positioning column 42 is provided on the inner wall of the transmission box 41; an arc-shaped slide 43 is provided at the bottom of the transmission box 41, and the meniscus 21 is slidably arranged on the arc-shaped slide 43, and the first end of the first funnel 2 is fixedly connected to the meniscus 21; the first end of the second funnel 3 is rotatably connected to the first positioning column 42, and the passive gear 31 is fixedly arranged on the first end of the second funnel 3, and the meniscus 21 is transmission-connected to the passive gear 31 through meshing teeth. The transmission box 41 is an open structure, and the opening of the transmission box 41 faces the first funnel 2 and the second funnel 3. In particular, the bottom inner wall of the transmission box 41 forms an arc-shaped slide 43, and the lower outer edge of the meniscus 21 is also an arc-shaped structure. The arc-shaped slide 43 of the transmission box 41 serves as a basis to support the meniscus 21 and the first end of the first funnel 2. The meniscus 21 can slide along the arc-shaped slide 43, so that the first end of the first funnel 2 can rotate on the transmission box 41. It can be understood that the first end of the first funnel 2 needs to be connected to the meniscus 21 through a transition structure 22, so that its flip center axis coincides with the center of the arc-shaped slide 43 and the meniscus 21.

[0032] Furthermore, the first positioning column 42 is arranged above the meniscus 21 and is fixedly connected to the inner wall of the transmission box 41, and the second funnel 3 can rotate around the first positioning column 42. It can be understood that the second funnel 3, the first positioning column 42, the first funnel 2, the meniscus 21 and the arc slide 43 are all arranged around the same rotation center axis. For this purpose, a notch needs to be opened on the transition structure 22 on the first funnel 2 to allow the second end of the second funnel 3 to pass through and be rotatably connected to the first positioning column 42.

[0033] The upper outer edge of the meniscus 21 is provided with meshing teeth, and meshes with the passive gear 31 through the meshing teeth. When the first funnel 2 is turned over, it can drive the second funnel 3 to rotate synchronously, and open the gap between the two to the maximum extent. In particular, this arrangement allows the first funnel 2 to only need to be turned no more than 90° to allow large pieces of food to fall into the feed port through the gap.

[0034] The first hinge also includes a planetary gear 44, and a second positioning column 45 is provided on the inner side wall of the transmission box 41, and the second positioning column 45 is provided between the first positioning column 42 and the meniscus 21; the planetary gear 44 is rotatably provided on the second positioning column 45, and the meniscus 21, the planetary gear 44 and the driven gear 31 are meshed and connected in sequence. Preferably, a planetary gear 44 is provided between the meniscus 21 and the driven gear 31 to transmit, so that the first funnel 2 and the second funnel 3 on the feed pipe 11 rotate in opposite directions, that is, the two move toward each other or move away from each other synchronously. In particular, the planetary gear 44 can play a role in amplifying and reducing the transmission ratio.

[0035] The outer side of the first funnel 2 is provided with a plate buckle 23, and the rotation angle range of the first funnel 2 is between 0°-45°, and the corresponding rotation angle range of the second funnel 3 is between 0°-90°. As above, the meniscus 21 is connected to the passive gear 31 through the planetary gear 44, so that the transmission ratio between the meniscus 21 and the passive gear 31 is greater than 1, and the preferred transmission ratio between the meniscus 21 and the passive gear 31 is 1:3, that is, the first funnel 2 rotates 30° to drive the second funnel 3 to rotate 90°, and the gap between the two is maximized, so that food can fall directly into the feeding tube 11.

[0036] The second hinge includes an axle seat 46 and a concentric shaft 24. The axle seat 46 is fixedly arranged on the other side of the upper port of the feed pipe 11, and the concentric shaft 24 is arranged on the second end of the first funnel 2. A concentric shaft sleeve 32 is arranged on the second end of the second funnel 3, and the two ends of the concentric shaft 24 are respectively inserted into the axle seat 46 and the concentric shaft sleeve 32. The second hinge is used to coaxially arrange the first funnel 2 and the second funnel 3 on the feed pipe 11, and the concentric shaft 24 is respectively connected to the axle seat 46 and the concentric shaft sleeve 32, so that the second ends of the first funnel 2 and the second funnel 3 are respectively rotatably connected to the axle seat 46, thereby realizing concentric rotation.

[0037] The upper end of the feed tube 11 is provided with a barrel sleeve 4, and a transmission box 41 and a shaft seat 46 are respectively provided on both sides of the upper end of the barrel sleeve 4. The barrel sleeve 4 is used to set the transmission box 41 and the shaft seat 46 to install the first hinge, the second hinge, the first funnel 2 and the second funnel 3. The existing feed barrel and the juice extraction barrel 12 of the juice extraction body 1 are an integrally formed structure, and the barrel sleeve 4 is provided with a detachable buckle structure, so that it is installed on the upper end of the feed barrel, thereby improving the existing product structure and reducing the difficulty of production.

[0038] The first funnel 2 and the second funnel 3 are paired with each other to form a storage chamber 17 on the upper end of the feed pipe 11. There is a material drop opening 18 between the first funnel 2 and the second funnel 3. The storage chamber 17 is connected to the feed pipe 11 through the material drop opening 18. The utility model also includes a pressing rod 5, which can pass through the material drop opening 18 and be inserted into the feed pipe 11. The first funnel 2 and the second funnel 3 are paired to form a structure similar to a hemisphere, so that the storage chamber 17 is bowl-shaped. In particular, there is a gap between the first funnel 2 and the second funnel 3 to form the material drop opening 18. The material drop opening 18 is the above-mentioned notch, which allows small pieces of food to fall directly, but still prevents human hands from entering the feed pipe 11. After the food is put into the feed pipe 11, the first funnel 2 and the second funnel 3 are in a closed state. At this time, the passable area of ​​the material drop opening 18 is the smallest. The pressing rod 5 can pass through the material drop opening 18 to enter the feed pipe 11 to push the food into the juicing chamber.

[0039] The first funnel 2 and the second funnel 3 are both provided with a support plate 33, and the support plate 33 is inserted into the material drop opening 18. Both sides of the pressing rod 5 are provided with a slide groove 51 for accommodating the support plate 33. Since the material drop opening 18 is provided between the first funnel 2 and the second funnel 3, in order to better prevent the entry of human hands, the support plates 33 are provided on the first funnel 2 and the second funnel 3 to limit the passability of the material drop opening 18. Of course, the support plates 33 also form the bottom support of the storage cavity 17.
