Description

Technical Field

[0001] The utility model relates to a structure of a handheld cooking appliance. Background Art

[0002] In the prior art, such as the Chinese utility model patent document with the publication number CN218279413U, a stirring rod device with a novel blade that can be lifted is disclosed, which includes a fixed housing. A motor is provided inside the fixed housing. The motor shaft of the motor extends downward through the fixed housing. The lower end of the motor shaft of the motor is fixedly connected with a cutter head. It also includes a material guide cover. An inlet for feeding is provided on the outer wall of the lower part of the material guide cover. The upper part of the material guide cover is movably connected with the fixed housing. The material guide cover can move up and down relative to the fixed housing. The cutter head extends downward into the material guide cover around the inlet.

[0003] Based on the above, in the prior art, the cutter head rotates inside the material guide cover to enable the material in the container to enter the material guide cover through the inlet and be chopped by the rotating cutter head. The technical problem existing in the existing stirring rod is that when the cutter head rotates at a high speed, eddy currents will be generated. The generation of eddy currents will cause the material guide cover to adsorb on the bottom wall of the container, resulting in difficulty in moving the entire stirring rod, and thus the user cannot adjust the position of the stirring rod, affecting the stirring and crushing efficiency. At the same time, the generation of eddy currents will also drive the material to rotate in one direction, making it difficult for the material to fully contact the cutter head and resulting in low whipping efficiency, which needs to be further improved.

[0033] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0034] See Figures 1-8, A structure of a handheld cooking appliance, including a cooking rod assembly 10 and a main body assembly 20. The cooking rod assembly 10 at least includes a cooking inner cover 110, a cooking outer cover 120, a knife shaft 130, and a cutter head 140 disposed at the lower end of the knife shaft 130. The interior of the cooking outer cover 120 is hollow and has openings at both the upper and lower ends. The cooking inner cover 110 is rotatably disposed inside the cooking outer cover 120. The interior of the cooking inner cover 110 is hollow and has openings at both the upper and lower ends. The knife shaft 130 is disposed inside the cooking inner cover 110, and the cutter head 140 is located inside the lower side of the cooking inner cover 110. A support portion 111 that abuts against the inner bottom surface of the container extends downward from the lower end surface of the cooking inner cover 110 or the lower end surface of the cooking outer cover 120. A driving assembly 30 for driving the relative rotation of the cooking inner cover 110 and the cooking outer cover 120 is disposed between the cooking rod assembly 10 and the main body assembly 20.

[0035] Based on the above embodiment, during use, the support portion abuts against the inner bottom wall of the container to form a support. In the normal use state, the main body assembly drives the knife shaft to drive the cutter head below to rotate, so as to realize the whipping of the material.

[0036] When turbulence is required, the driving assembly drives the relative rotation of the cooking inner cover and the cooking outer cover. During this rotation process, the cover body provided with the support portion abuts against and supports the container, while the other cover body rotates to cause turbulence, so as to disrupt the vortex generated by the rotation of the cutter head, to solve the problem that the vortex drives the material to rotate in one direction and affects the whipping efficiency. At the same time, it can also prevent the cooking rod from being adsorbed on the inner bottom wall of the container due to the vortex.

[0037] See Figure 3 , During use, the cooking rod assembly 20 extends into the container to whip the material. The material located in the container enters the interior of the cooking inner cover 110 from the notch 122 at the bottom of the cooking outer cover 120 through the material groove 112 at the bottom of the cooking inner cover 110 and comes into contact with the cutter head 140, so as to realize the whipping of the material.

[0038] See Figure 5 , The driving assembly 30 includes a driven member 310 and a driving member 320 that are threadedly connected to each other. The support portion 111 is disposed on the lower end surface of the cooking inner cover 110. The driven member 310 is fixedly connected to the cooking outer cover 120. The driving member 320 is fixedly connected to the main body assembly 20. When the main body assembly 20 moves up and down relative to the cooking rod assembly 10, the driving member 320 drives the driven member 310 to rotate through threaded cooperation, so as to drive the cooking outer cover 120 to rotate relative to the cooking inner cover 110. In this embodiment, the support portion and the cooking inner cover are integrated to form a support by fitting with the bottom wall of the container. See Figure 2, the spacing formed between the downwardly extending support portion 111 and the lower surface of the cooking outer cover 120 allows a space to be formed between the cooking outer cover 120 and the bottom wall of the container when the support portion fits against the bottom wall of the container, preventing the cooking outer cover 120 from contacting the bottom wall of the container. During use, by pressing down on the main body assembly, the main body assembly drives the driving member 320 to move downward. During this process, since the driven member 310 cannot move downward and is in a threaded engagement with the driving member 320, the downward movement of the driving member 320 causes the driven member 310 to rotate, thereby enabling the driven member 310 to drive the cooking outer cover 120 to rotate relative to the cooking inner cover 110, and thus generating a turbulent flow through the lower portion of the cooking outer cover 120.

[0039] See Figure 5 and Figure 6 , both the driven member 310 and the driving member 320 are provided with a hollow interior and open upper and lower ends; the upper end of the cutter shaft 130 passes through the driven member 310 and the driving member 320 and is in transmission connection with the main body assembly 20.

[0040] See Figure 5 and Figure 6 , a spiral track 330 is provided on the driving member 320, and a track portion 340 that cooperates with the spiral track 330 is provided on the driven member 310.

[0041] Further, see Figure 5 and Figure 6 , the spiral track 330 is a spiral rib, and the track portion 340 is a bump.

[0042] See Figure 5 and Figure 6 , both the driving member 320 and the driven member 310 are in a ring structure, the driving member 320 is sleeved outside the driven member 310, the spiral track 330 is provided on the inner wall of the driving member 320, and the track portion 340 is provided on the outer wall of the driven member 310.

[0043] See Figure 5 and Figure 6 , a limiting member 350 that abuts against the track portion 340 is provided on the driving member 320. The limiting member 350 is used to restrict the maximum upward movement stroke of the driving member 320 relative to the driven member 310 to prevent the two from separating from each other.

[0044] See Figure 6 and Figure 7, a driven coupler 131 is provided at the upper end of the cutter shaft 130. The main machine assembly 20 includes a machine housing 210 and a motor 220 disposed within the machine housing 210. A motor shaft of the motor 220 is provided with a driving coupler 230 that is coupled and driven with the driven coupler 131. In this embodiment, the driving coupler 230 and the driven coupler 131 are coupled by inserting along the axial direction of the cutter shaft 130.

[0045] See Figure 8 , a connecting member 211 is fixedly connected to the lower end of the machine housing 210, and the connecting member 211 is detachably connected to the driving member 320. In this embodiment, the driving assembly 30 is installed in the installation cavity 100 at the upper part of the cooking stick assembly 10. When assembling the cooking stick assembly 10 and the main machine assembly 20,

[0046] See Figure 5 and Figure 6 , the driving assembly 30 further includes a return spring 40 for providing an upward acting force to the driving member 320. The function of the return spring 40 is to provide an upward reset acting force for the driving member 320. When the main machine assembly 20 drives the driving member 320 to press down and eliminates the acting force applied to the main machine assembly 20, the return spring 40 releases the stored energy and drives the driving member 320 and the driving assembly 30 to reset upward.

[0047] Furthermore, the driving member 320 is connected to the upper end of the return spring 40, and the lower end of the return spring 40 is connected to the driven member 310 or the cooking outer cover 120.

[0048] See Figures 2-4 , a plurality of through slots 112 penetrating inside and outside are provided at the bottom of the cooking inner cover 110.

[0049] See Figure 3 , a plurality of through notches 122 penetrating inside and outside are provided at the bottom of the cooking outer cover 120.
