Abstract
Description
Technical Field
[0001] This utility model relates to the field of food preparation equipment technology, and in particular to a snap-fit structure for a cylindrical dicing cutter. Background Technology
[0002] A salad machine is an automated electrical appliance that can cut vegetables and fruits to make salads. It has multiple interchangeable cutting modules that can handle common salad ingredients such as lettuce, tomatoes, cucumbers, and carrots. It typically supports shredding, slicing, dicing, and other cutting methods.
[0003] Existing salad machines require a cylindrical dicing cutter and a slicing cylinder to cut square-shaped ingredients into cubes. The slicing cylinder is coaxially mounted outside the cylindrical dicing cutter and connected to the output shaft of the power unit. The cylindrical dicing cutter does not rotate; each rotation of the slicing cylinder forces a slice of ingredient downwards through the dicing blade mesh of the cylindrical dicing cutter. Because the dicing blade mesh is a crisscrossing mesh, the sliced ingredient is cut into square cubes as it passes through. However, in existing salad machines, the outer edge of the cylindrical dicing cutter is secured in slots on the outer edge of the discharge cylinder cavity by evenly distributed circumferential arc-shaped clamps. This is similar to the locking mechanism disclosed in the design patent CN307816537S. However, this rotating clamping method is prone to loosening during prolonged operation of the salad machine, and detachment can lead to difficulties in the dicing process.
[0004] Therefore, it is necessary to develop a snap-fit structure for a cylindrical dicing cutter to address the aforementioned defects. Utility Model Content
[0005] The purpose of this utility model is to provide a snap-fit structure for a cylindrical dicing cutter, which uses a locking device to fix the cylindrical dicing cutter in an axial locking manner so that it is not easy to fall off.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This utility model discloses a snap-fit structure for a cylindrical dicing cutter, which is installed between the material main housing of a salad machine and the cylindrical dicing cutter. The cylindrical dicing cutter is coaxially installed in the discharge cylindrical cavity with the axis horizontal. It includes a locking device and a circumferential limiting structure. The locking device uses a plug-in method to axially lock the cylindrical dicing cutter in the discharge cylindrical cavity, and the circumferential limiting structure circumferentially locks the cylindrical dicing cutter in the discharge cylindrical cavity.
[0008] Furthermore, the locking device includes a locking device cover and a locking core. The material host housing is integrally provided with a locking device bottom shell with top and bottom openings above the outer edge of the discharge cylindrical cavity. The locking device cover is detachably fastened to the top opening of the locking device bottom shell and confines the locking core within the locking slide cavity. The locking core can slide up and down within the locking slide cavity. An insertion port is provided on the outer ring platform at the outer end of the cylindrical dicing device. The locking tongue at the bottom end of the locking core can protrude from the bottom opening of the locking slide cavity and be inserted into the insertion port.
[0009] Furthermore, it also includes a compression spring. The back of the locking core main board is vertically provided with a compression spring groove with a top opening. The bottom plate of the locking slide cavity is vertically provided with a central rib plate in the middle. The top of the central rib plate protrudes outward to form a stop beam. The compression spring is installed in the compression spring groove. The bottom end of the compression spring abuts against the bottom surface of the compression spring groove, and the top end of the compression spring abuts against the stop beam.
[0010] Furthermore, the front of the locking core main board is provided with a paddle that protrudes from the guide hole of the locking device cover.
[0011] Furthermore, the outer edge of the inner end face of the outer ring platform is chamfered, and the inner edge of the bottom end face of the locking tongue is chamfered.
[0012] Furthermore, the circumferential limiting structure includes limiting protrusions and limiting slots. The limiting slot is a rectangular opening and is located directly above the outer edge of the discharge cylinder cavity. Two limiting protrusions are symmetrically arranged on both sides of the insertion port and near the outer end shoulder of the outer ring platform. The outer side walls of the two limiting protrusions are limited to the inner side of the narrow side of the limiting slot.
[0013] Furthermore, the outer ring platform is provided with an outwardly growing discharge bottom edge on the side opposite to the limiting protrusion.
[0014] Compared with the prior art, the advantages of the snap-fit structure for a cylindrical dicing tool of this utility model are as follows:
[0015] This utility model discloses a snap-fit structure for a cylindrical dicing cutter. The locking device uses a plug-in method to axially lock the cylindrical dicing cutter, which can effectively prevent the cylindrical dicing cutter from coming out of the discharge cylinder cavity. The circumferential limiting structure circumferentially locks the cylindrical dicing cutter, which can prevent the cylindrical dicing cutter that needs to be fixed from rotating in the discharge cylinder cavity.
[0016] Furthermore, the locking cover is detachably fastened to the top opening of the locking device's bottom shell, allowing for maintenance and replacement of the locking core. The locking tongue, inserted from top to bottom, provides excellent anti-disengagement properties, reducing the likelihood of disengagement. The added compression spring ensures the locking core remains in a low position under normal conditions, reliably locking the cylindrical cutter. The central rib plate increases structural strength against the spring's reaction force, preventing bending and deformation of the locking device's bottom shell top plate. Two chamfers are added to the outer edge of the inner end face of the outer ring platform and the inner edge of the bottom end face of the locking tongue. When the cylindrical cutter is installed into the discharge cylinder cavity, the outer ring platform can use these chamfers to lift the locking tongue upwards without the need for additional pushers. The limiting protrusions provide reliable circumferential limiting with a simple structural feature. The outwardly extending discharge bottom edge on the opposite side of the limiting protrusions ensures the discharge bottom edge is at its lowest position, reducing the risk of material spillage.

[0027] The core of this utility model is to provide a snap-fit structure for a cylindrical dicing cutter, which uses a locker to fix the cylindrical dicing cutter in an axial locking manner so that it is not easy to fall off.
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Refer to the attached diagram. Figure 1 A three-dimensional structural diagram of a salad machine equipped with the snap-fit structure for the cylindrical dicing cutter of this utility model; Figure 2 This is a three-dimensional structural diagram of the snap-fit structure for the cylindrical dicing tool of this utility model; Figure 3 for Figure 2 A magnified schematic diagram of a portion of the central I section; Figure 4 for Figure 2 Front view sectional structural diagram; Figure 5 This is a three-dimensional structural diagram of the cylindrical dicing tool and slicing tube assembled in this utility model; Figure 6 This is a three-dimensional structural diagram of the material handling unit housing in this utility model; Figure 7 This is a three-dimensional structural diagram of the locking device cover in this utility model; Figure 8 This is a schematic diagram of the three-dimensional structure of the locking core in this utility model.
[0031] In one specific implementation, such as Figures 1-8 As shown, the cylindrical dicing device of this utility model is installed between the material main housing 2 and the cylindrical dicing device 1 of the salad machine using a snap-fit structure. The cylindrical dicing device 1 is coaxially arranged in the discharge cylindrical cavity 204 with the axis horizontal. The slicing cylinder 5 is rotatably and coaxially sleeved on the inward end of the cylindrical dicing device 1. The material main housing 2 is detachably installed in the mounting slot of the power main unit 7. The output shaft of the power main unit 7 drives the slicing cylinder 5 to rotate relative to the discharge cylindrical cavity 204.
[0032] The present invention relates to a snap-fit structure for a cylindrical dicing cutter, comprising a locking device and a circumferential limiting structure. The locking device uses a plug-in method to axially lock the cylindrical dicing cutter 1 within the discharge cylindrical cavity 204, and the circumferential limiting structure circumferentially locks the cylindrical dicing cutter 1 within the discharge cylindrical cavity 204.
[0033] The locking device uses a plug-in method to axially lock the cylindrical dicer 1, which can effectively prevent the cylindrical dicer 1 from coming out of the discharge cylindrical cavity 204; the circumferential limiting structure uses a circumferential locking device to prevent the cylindrical dicer 1, which needs to be fixed, from rotating in the discharge cylindrical cavity 204.
[0034] In one specific embodiment of this utility model, such as Figures 1-8 As shown, the locking device includes a locking cover 3 and a locking core 4. The material handling unit housing 2 has a locking bottom shell 201 with top and bottom openings integrally formed above the outer edge of the discharge cylindrical cavity 204, and its inner cavity is defined as the locking slide cavity. The locking cover 3 is detachably fastened to the top opening of the locking bottom shell 201 and confines the locking core 4 within the locking slide cavity. The locking core 4 can slide vertically within the locking slide cavity. An insertion port 103 is provided on the outer ring 102 at the outer end of the cylindrical dicing cutter 1. The locking tongue 402 at the bottom end of the locking core 4 can protrude from the bottom opening of the locking slide cavity and be inserted into the insertion port 103.
[0035] Specifically, such as Figure 6 and Figure 8 As shown, the bottom opening of the locking slide cavity is not completely open, and a stop edge with a side wall height of about half is provided on the bottom wall. The locking core 4 is provided with a stop edge 401 facing inward. The stop edge 401 slides on the bottom plate of the locking slide cavity, and the stop edge can limit the bottom end face of the stop edge 401.
[0036] Specifically, such as Figure 6 and Figure 7 As shown, latches 302 are provided on both sides of the locking cover 3, and inner slots 202 are correspondingly provided on the two inner sidewalls of the locking slide cavity. The latches 302 can be inserted into the inner slots 202 to fix the locking cover 3.
[0037] The locking cover 3 can be detachably fastened to the top opening of the locking base 201, allowing for the maintenance and replacement of the locking core 4. At the same time, the locking tongue 402, which is inserted from top to bottom into the insertion port 103, provides good anti-disengagement and reduces the occurrence of disengagement.
[0038] Obviously, the locking device can also be locked using a cylindrical pin, and similar simple replacement methods also fall within the protection scope of this utility model.
[0039] In one specific embodiment of this utility model, such as Figure 4 , Figure 6 and Figure 8 As shown, the locking device also includes a compression spring. A compression spring groove 404 with a top opening is vertically arranged on the back of the main plate of the locking core 4. A central rib plate 205 is vertically arranged in the middle of the bottom plate of the locking slide cavity, with a stop beam protruding outward from the top of the central rib plate 205. The compression spring is installed within the compression spring groove 404, with its bottom end abutting against the bottom surface of the compression spring groove 404 and its top end abutting against the stop beam.
[0040] It should be noted that, in order to simplify the illustration of the main structural features, the compression spring is not shown in the patent illustration and should not be regarded as a limitation of this utility model.
[0041] By adding the compression spring, the locking core 4 can be kept in a low position under normal conditions, ensuring reliable locking of the cylindrical cutter 1. The central rib plate 205 increases the structural strength against the reaction force of the compression spring, preventing the top plate of the locking device bottom shell 201 from bending and deforming.
[0042] In one specific embodiment of this utility model, such as Figures 1-4 and Figure 8 As shown, the main board of the locking core 4 has a paddle 403 on its front side, which protrudes from the guide hole 301 of the locking device cover 3. It is manufactured by injection molding. The paddle 403 allows the operator to manually pull the locking core 4 upward, causing it to slide upward along the locking cavity. The locking tongue 402 then exits the insertion port 103, completing the disengagement of the cylindrical cutter 1, which can then be disassembled and removed.
[0043] Specifically, such as Figure 4 and Figure 8 As shown, the outer edge of the inner end face of the outer ring platform 102 is chamfered, and the inner edge of the bottom end face of the locking tongue 402 is chamfered, with the inclination angles of the two chamfers being the same.
[0044] By adding two chamfers on the outer edge of the inner end face of the outer ring platform 102 and the inner edge of the bottom end face of the locking tongue 402, when the cylindrical cutter 1 is installed into the discharge cylindrical cavity 204, the outer ring platform 102 can lift the locking tongue 402 upwards by relying on the inclined surface at this location, without the need for additional push-pull paddle 403.
[0045] In one specific embodiment of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, the circumferential limiting structure includes limiting protrusions 104 and limiting slots 203. The limiting slots 203 are rectangular openings located directly above the outer edge of the discharge cylindrical cavity 204. Two limiting protrusions 104 are symmetrically arranged on both sides of the insertion port 103, near the outer shoulder of the outer end of the outer ring platform 102. The outer walls of the two limiting protrusions 104 are limited to the inner side of the narrow side of the limiting slots 203.
[0046] Obviously, the two limiting protrusions 104 can also be replaced by limiting strips, the short sidewall spacing of which is adapted to the narrow side spacing of the limiting groove 203. Similar simple replacement methods all fall within the protection scope of this utility model.
[0047] Specifically, such as Figure 4 and Figure 5 As shown, the outer ring platform 102 has an outwardly growing discharge bottom edge 105 on the side opposite to the limiting protrusion 104, and the discharge bottom edge 105 discharges the food material.
[0048] With the setting of the limiting protrusion 104, a reliable circumferential limiting can be achieved with simple structural features; by setting an outwardly growing discharge bottom edge 105 on the opposite side of the limiting protrusion 104, it is ensured that the discharge bottom edge 105 is exactly at the lowest position, and the risk of material scattering is reduced.
[0049] The operation of the snap-fit structure for this cylindrical dicing device is as follows: During installation, the slicing cylinder 5 is coaxially fitted onto the inward-facing end of the cylindrical dicing device 1, with the outer edge of the slicing cylinder 5 inserted into the outer ring platform 102. Then, the sub-assembly of the cylindrical dicing device 1 and the slicing cylinder 5 is inserted into the discharge cylindrical cavity 204. During insertion, the chamfered outer edge of the inner end face of the outer ring platform 102 pushes upward against the chamfered inner edge of the bottom end face of the locking tongue 402, causing the locking tongue 402 to rise. After the locking tongue 402 aligns with the insertion port 103, it automatically falls into the insertion port 103 with a click, completing axial locking. Simultaneously, the power interface 501 on the back of the slicing cylinder 5 is connected to the output shaft of the power unit 7. At the same time, two limiting protrusions 104 engage with the limiting grooves 203, completing circumferential limiting. Turning on the salad machine allows food to be fed into the material handling unit 2 through the feeding port at the top. The feed rod pushes the food downwards, and each rotation of the slicing cylinder 5 causes the slicing blade 501 at its cutting edge to cut a piece of food, squeezing it downwards through the dicing blade mesh 101 of the cylindrical dicer 1. The food is then diced and enters the inner cavity of the cylindrical dicer 1, gradually flowing out from the discharge bottom edge 105 into the receiving container. After dicing, the operator manually moves the locking core 4 upwards, causing it to slide upwards along the locking slide cavity. The locking tongue 402 disengages from the insertion port 103, disengaging the cylindrical dicer 1. The sub-assembly of the cylindrical dicer 1 and the slicing cylinder 5 can then be removed from the discharge cylinder cavity 204 for easy cleaning.
[0050] In summary, the snap-fit structure of this utility model's cylindrical dicing cutter, through the locking device's insertion method, axially locks the cylindrical dicing cutter 1, effectively preventing it from detaching from the discharge cylindrical cavity 204. The circumferential limiting structure circumferentially locks the cylindrical dicing cutter 1, preventing it from rotating within the discharge cylindrical cavity 204. Furthermore, the locking device cover 3, detachably fastened to the top of the locking device's bottom shell 201, allows for maintenance and replacement of the locking core 4. Simultaneously, the locking tongue 402, inserted from top to bottom into the insertion port 103, provides good anti-detachment performance, reducing the occurrence of disengagement. The addition of the compression spring ensures that the locking core 4 is normally in a low position, reliably locking the cylindrical dicing cutter 1. The central rib plate 205 increases the structural strength against the reaction force of the compression spring, preventing bending and deformation of the top plate of the locking device's bottom shell 201. By adding two chamfers on the outer edge of the inner end face of the outer ring platform 102 and the inner edge of the bottom end face of the locking tongue 402, when the cylindrical cutter 1 is installed into the discharge cylindrical cavity 204, the outer ring platform 102 can lift the locking tongue 402 upwards by relying on the inclined surface at this location, without the need for an additional pusher 403. Through the setting of the limiting protrusion 104, reliable circumferential limiting can be achieved with simple structural features; by providing an outwardly growing discharge bottom edge 105 on the opposite side of the limiting protrusion 104, it is ensured that the discharge bottom edge 105 is exactly at the lowest position, reducing the risk of material spillage during discharge.
