[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0051] In this application, the terms "first", "second" and the like are used to distinguish different components with the same name, and do not have the meaning of order, importance or other meanings. The terms "forward" and "reverse" in this application are used to indicate two opposite directions, and do not refer to specific directions. The term "plural" in this application includes two or more situations.
[0052] Figures 1 to 3 The external structure, cross-sectional view and exploded state of the cutter assembly 100 of the preferred embodiment are shown respectively. Figures 1 to 3 The cutter assembly 100 includes a rotating shaft assembly, on which three blades 105 are disposed, and the three blades 105 are all perpendicular to the rotating shaft assembly.
[0053] The rotating shaft assembly has three shafts, which are mutually sleeved and the axes coincide with each other. For the convenience of description, the central axis is referred to as the first core shaft 102 in this application, and the remaining axes are referred to as the first outer shafts 103. Therefore, specifically in this embodiment, there are two first outer shafts 103, one of which is sleeved on the outside of the first core shaft 102, hereinafter referred to as the inner first outer shaft 103, and the other outer shaft is sleeved on the outside of the aforementioned first outer shaft 103, hereinafter referred to as the outer first outer shaft 103.
[0054] like Figure 3 As shown, the end (upper end in the figure) of the first mandrel 102 is provided with a polygonal inner hole, which serves as the first transmission part 101 for driving the device 200 (see Figure 5 ) is coupled to the polygonal inner hole to drive the first spindle 102 to rotate. The first spindle 102 has a shaft seat hole 107 at the head end (the lower end in the figure). The axis of the shaft seat hole 107 coincides with the axis of the first spindle 102. The shaft seat hole 107 is used to be connected to the shaft seat 410 (see Figure 5) to vertically support the rotating shaft assembly in the fruit and vegetable cavity 400. In addition, the head end (the lower end in the figure) of the first core shaft 102 is connected to an end cover 106 by a screw 1061, and the shaft seat hole 107 is configured on the end cover 106. Through the end cover 106, the two first outer shafts 103 and the three blades 105 are combined on the first core shaft 102. After the end cover 106 is removed from the first core shaft 102, any blade 105 can be easily removed.
[0055] like Figure 3 As shown, the end (upper end in the figure) of the outer first outer shaft 103 is provided with a plurality of vertical convex strips on the inner peripheral wall, constituting the first transmission part 101 of the outer first outer shaft 103, which is used to drive the device 200 (see Figure 5 ) is coupled to the first transmission part 101 to drive the outer first outer shaft 103 to rotate.
[0056] like Figure 3 As shown, the end (upper end in the figure) of the inner first outer shaft 103 is provided with a plurality of vertical convex strips on the outer peripheral wall, constituting the first transmission part 101 of the inner first outer shaft 103, which is used to drive the device 200 (see Figure 5 ) is coupled to the first transmission part 101 to drive the inner first outer shaft 103 to rotate.
[0057] like Figure 3 As shown, the three blades 105 are respectively provided with a polygonal coupling hole 1051, through which the blades 105 are correspondingly assembled on the first mandrel 102 or the first outer shaft 103, so that on the one hand, when the first mandrel 102 or the first outer shaft 103 rotates, the corresponding blades 105 are driven to rotate, and on the other hand, the blades 105 can be easily removed from the first mandrel 102 or the first outer shaft 103. It should be understood that in addition to the polygonal hole, the coupling hole 1051 can also be a special-shaped hole, an elliptical hole or a semicircular hole to achieve the above purpose.
[0058] like Figure 2As shown, in this embodiment, from bottom to top, the three blades 105 are coupled to the first mandrel 102, the inner first outer shaft 103 and the outer first outer shaft 103 respectively. When the first mandrel 102 and the outer first outer shaft 103 are driven to rotate clockwise, and the inner first outer shaft 103 is driven to rotate counterclockwise, the upper blade 105 and the lower blade 105 will be driven to rotate clockwise, and the middle blade 105 will be driven to rotate counterclockwise; conversely, the upper blade 105 and the lower blade 105 will be driven to rotate counterclockwise, and the middle blade 105 will be driven to rotate clockwise. That is, the structure of the above-mentioned cutter assembly 100 enables the three blades 105 to be driven by the shaft assembly to rotate in two opposite directions at the same time. Compared with a cutter that rotates in a single direction, the cutter assembly 100 of this embodiment has the characteristic of higher efficiency.
[0059] If clockwise rotation is referred to as forward rotation, then two of the three blades 105 are forward rotating blades 105 and the other is a reverse rotating blade 105, or one is a forward rotating blade 105 and the other two are reverse rotating blades 105. In this embodiment, the forward rotating blades 105 and the reverse rotating blades 105 are alternately arranged along the axial direction of the rotating shaft assembly.
[0060] Reference Figure 2 and Figure 3 Furthermore, the shaft assembly is provided with a partition 104 between adjacent blades 105 for axially positioning the blades 105 so that each blade 105 will not move in the axial direction.
[0061] Based on the above, it should be understood by those skilled in the art that only two blades 105 may be configured, one rotating forward and the other rotating reversely; or four blades 105 may be configured, two rotating forward and the other two rotating reversely; and so on.
[0062] In addition, as a suboptimal implementation, the blade 105 may also be connected to the shaft in the rotating shaft assembly in a fixed connection manner, and the fixed connection manner that may be adopted includes but is not limited to welding, riveting, or one-piece molding process, etc. In this suboptimal implementation, when the blade 105 is worn, the cutter assembly 100 needs to be replaced as a whole, and the use cost is relatively high.
[0063] Figure 4-Figure 5 The structure of a fruit and vegetable cutter according to a preferred embodiment is shown. Figure 6 to Figure 7 The structure of the driving device 200 is shown. Figures 4 to 5As shown, the fruit and vegetable cutter includes a fruit and vegetable chamber 400, a driving device 200 and a cutting blade assembly 100. A shaft seat 410 is provided at the center of the bottom of the fruit and vegetable chamber 400; the driving device 200 is arranged at the top of the fruit and vegetable chamber 400, and can synchronously output clockwise rotation torque and counterclockwise rotation torque with the same rotation center. In addition, a handle 300 is also provided on one side of the fruit and vegetable chamber 400.
[0064] Reference Figures 4 to 7 The structure of the driving device 200 specifically includes: two power input shafts 230, a power output shaft 210, an intermediate gear 220, a reversing gear 240, and a crank 250. The power input shaft 230, the power output shaft 210, the intermediate gear 220, and the reversing gear 240 are each supported on the top of the fruit and vegetable cavity 400 through an axis.
[0065] like Figure 7 As shown, the power output shaft 210 has a second core shaft 211 and two second outer shafts 212, wherein one of the second outer shafts 212 is sleeved outside the second core shaft 211 and is referred to as the inner second outer shaft 212 for the convenience of description, and the other second outer shaft 212 is sleeved outside the aforementioned second outer shaft 212 and is referred to as the outer second outer shaft 212 for the convenience of description.
[0066] like Figure 6 , Figure 7 As shown, the intermediate gear 220 is arranged between the power input shaft 230 and the power output shaft 210, and is coupled with the gear on the inner second outer shaft 212. The gears on the two power input shafts 230 are respectively coupled with the intermediate gear 220, and the tooth ratios of the two power input shafts 230 and the intermediate gear 220 are different. For the convenience of description, one power input shaft 230 is called a common shaft according to its actual function, and the other power input shaft 230 is called a labor-saving shaft.
[0067] like Figure 6 , Figure 7 As shown, the reversing gear 240 is configured between the intermediate gear 220 and the power output shaft 210. On the one hand, the reversing gear 240 is coupled to the intermediate gear 220, and on the other hand, the main gear and the sub-gear of the reversing gear 240 are coupled to the gears on the second core shaft 211 and the gears on the outer second outer shaft 212 correspondingly.
[0068] The crank handle 250 can be inserted into the corresponding power input hole on the top cover of the fruit and vegetable cutter, and coupled with the gear on the corresponding power input shaft 230 (ordinary shaft or labor-saving shaft).
[0069] The cutter assembly 100 is the cutter assembly of the aforementioned preferred embodiment, Figure 5 , Figure 7 , Figure 2The shaft seat hole 107 on the cutter assembly 100 cooperates with the shaft seat 410 at the bottom of the fruit and vegetable cavity 400 to support the cutter assembly 100 in the fruit and vegetable cavity 400. The second core shaft 211, the inner second outer shaft 212, and the outer second outer shaft 212 of the power output shaft 210 of the driving device 200 are correspondingly coupled with the first core shaft 102, the inner first outer shaft 103, and the first transmission part 101 at the end (upper end in the figure) of the outer first outer shaft 103 of the cutter assembly 100.
[0070] When the crank 250 is turned, the power input shaft 230 drives the inner second outer shaft 212 to rotate through the intermediate gear 220, and then drives the inner first outer shaft 103 to rotate clockwise. At the same time, the intermediate gear 220 drives the reversing gear 240 to rotate, and the reversing gear 240 drives the second mandrel 211 and the second outer shaft 212 of the outer guillotine to rotate synchronously, and then drives the first mandrel 102 and the outer first outer shaft 103 to rotate synchronously counterclockwise, so that the upper blade 105 and the lower blade 105 rotate synchronously counterclockwise, and the middle blade 105 rotates synchronously clockwise. That is, when the handle 300 is shaken, the three blades 105 rotate synchronously in two opposite directions.
[0071] The fruit and vegetable cutter of the preferred embodiment can be used by different groups of people. When used by adults, the crank 250 is coupled to the common shaft. When used by children or the elderly, the crank 250 is coupled to the labor-saving shaft.
[0072] Based on the above, it can be understood that by coupling the intermediate gear 220 with the second core shaft 211 and the outer second outer shaft 212, and coupling the reversing gear 240 with the inner second outer shaft 212, the purpose of synchronously rotating the three blades 105 in opposite directions when the handle 300 is shaken can be achieved.
[0073] The fruit and vegetable cutter may further include a stirring component. Figure 8 FIG. 5 shows a structure of a stirring assembly 500. Figure 8 As shown, the stirring assembly 500 includes two blades 501, one is a forward rotating blade and the other is a reverse rotating blade. The two blades 501 each have a shaft 502, and the ends of the shafts 502 are each provided with a second transmission part 503 for coupling to the driving device 200. The two blades 501 are stacked, and the shafts 502 of the two blades 501 are nested and the axes coincide.
[0074] When in use, the cutter assembly 100 is removed, and the two second transmission parts 503 of the stirring assembly 500 are connected to the second mandrel 211 and the second outer shaft 212 of the power output shaft 210 of the driving device 200. As mentioned above, when the crank 250 is turned, the second mandrel 211 and the second outer shaft 212 rotate synchronously in opposite directions, so that the two blades 501 of the stirring assembly 500 are driven to rotate synchronously in opposite directions. It can be used to stir liquids such as egg liquid.
[0075] Different power output shafts can be selected for use according to different applications. For example, when beating eggs, since the resistance is small, the crank 250 can be selected to be coupled with the ordinary shaft. When cutting vegetables or using fruits and vegetables with a harder texture, since the resistance is large, it is preferred to couple the crank 250 with the labor-saving shaft.
[0076] The cutter assembly 100 of the present invention can also be applied to a juicer, a meat grinder, etc.
[0077] The present invention is described in detail above through specific embodiments, and these detailed descriptions are only limited to helping those skilled in the art understand the content of the present invention, and cannot be understood as limiting the scope of protection of the present invention. Various modifications, equivalent transformations, etc. made by those skilled in the art to the above scheme under the conception of the present invention should be included in the scope of protection of the present invention.
