Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a handheld telescopic food processor. Background Technology

[0002] Handheld food processors, as portable kitchen appliances, are popular among consumers due to their compact size, ease of use, and versatility. Users can quickly blend, chop, and mix ingredients using a handheld food processor, making them widely applicable in various scenarios such as fruit and vegetable juices, baby food, and sauces.

[0003] In existing handheld blender technology, to achieve effective processing of ingredients at different depths, some products feature a movable blade shaft. During use, the user applies a downward force to the blender's main unit, causing the main unit to move the blade shaft downwards, thereby adjusting the contact position between the blade and the food to meet different cooking needs. However, most handheld blenders on the market currently use a one-piece metal structure design for the blender's cover, located at the bottom to protect the blade and guide food into the cutting area. While the metal cover offers high strength and durability, ensuring stability during the cutting process, it has significant drawbacks in practical use. When the blender is working, the metal cover contacts and rubs against the bottom of the container. Due to the high strength of the metal, it easily scratches the inner wall of coated containers or scratches plastic containers, even scraping plastic filaments. These scraped coating fragments or plastic filaments can easily get mixed into the food being processed, affecting not only the quality and taste of the food but also potentially posing a health hazard to consumers.

[0032] See Figures 1-4A handheld telescopic blender includes a blender body 10, a plastic blending cover 20, a blade shaft 30, and a blade head 40. The lower end of the blender body 10 is connected to the plastic blending cover 20. The interior of the blender body 10 is hollow, forming a moving channel 100, which is in communication with the interior of the plastic blending cover 20. The blade shaft 30 is movably disposed within the moving channel 100 along its axial direction. The lower end of the blade shaft 30 extends into the plastic blending cover 20 and is connected to the blade head 40. An elastic element 300 is connected between the blender body 10 and the blade shaft 30, and the elastic element 300 is used to apply force to the blade shaft 30 to constrain the blade shaft 30 to remain in a first position. When a user uses a food processor to process ingredients, applying a downward force to the main unit 70 causes the main unit 70 to move the blade shaft 30 downwards. This force overcomes the force of the elastic element 300, allowing the blade shaft 30 to move downwards along the axis of the moving channel 100, thereby moving the blade head 40 downwards. By changing the position of the blade head 40, the cutting and pulverizing are more thorough. In this embodiment, compared to a traditional metal food processor cover, the plastic food processor cover 20 is softer. Even if it rubs against the bottom of the container, it can effectively reduce the risk of scratching the inner wall of the coated container or the plastic container, preventing coating fragments or plastic filaments from getting into the food, thus ensuring the safety and hygiene of the food processing process.

[0033] See Figure 1 and Figure 3 The plastic blending cover 20 is provided with an upwardly extending connecting sleeve 210 that is detachably connected to the moving channel 100. A bearing 50 is disposed within the connecting sleeve 210, and the blade shaft 30 is disposed within the bearing 50 and is rotatable and movable relative to the bearing 50. When the blender is working, the blade shaft 30 drives the blade head 40 to rotate at high speed. The bearing 50 effectively reduces the frictional resistance during the rotation of the blade shaft 30, ensuring smoother and more stable rotation of the blade head 40, thus improving the efficiency and effect of food blending and pulverization. Simultaneously, when the user applies external force to the blender body 10, causing the blade shaft 30 to move along the axis of the moving channel 100, the bearing 50 ensures the smoothness of the blade shaft 30's movement, preventing jamming. This allows the blade head 40 to precisely and flexibly adjust its contact position with the food, meeting diverse cooking needs.

[0034] Furthermore, the connecting sleeve 210 is connected to the moving channel 100 using existing connection structures such as snap-fit.

[0035] See Figure 1 and Figure 3A limiting member 60 is detachably connected inside the connecting sleeve 210 above the bearing 50, and the lower end of the limiting member 60 abuts against the upper end of the bearing 50. The limiting member 60 is used to constrain the bearing 50, keeping the bearing 50 within the connecting sleeve 210.

[0036] See Figure 1 and Figure 3 A sealing sleeve 510 is provided between the bearing 50 and the connecting sleeve 210. The sealing sleeve 510 not only restrains the installation of the bearing 50, but also ensures the stability of its installation.

[0037] See Figure 1 and Figure 3 The lower end of the sealing sleeve 510 extends downward and fits against the outer wall of the cutter shaft 30. The sealing sleeve 510 fits against the cutter shaft 30 to prevent material inside the plastic cooking cover 20 from splashing upward into the moving channel 100.

[0038] Furthermore, the limiting member 60 has an annular structure, and the cutter shaft 30 passes through the limiting member 60.

[0039] See Figure 3 and Figure 4 The plastic cooking cover 20 has a first connecting port 230 and a second connecting port 220 arranged in an array along its circumference. The first connecting port 230 and the second connecting port 220 are used to connect the inside and outside of the plastic cooking cover 20. When the blade head 40 rotates and generates a vortex, the negative pressure generated inside the plastic cooking cover 20 will draw material from outside the plastic cooking cover 20 into the inside, and the vortex will also throw the material out of the plastic cooking cover 20. The arrangement of the two connecting ports, the first connecting port 230 and the second connecting port 220, can improve the efficiency of material flow, thereby allowing the material to better contact the blade head, making the cutting and pulverizing more efficient.

[0040] See Figure 3 The food processor body 10 is provided with an extension cover 101 that fits against the outer wall of the plastic food processor cover 20. A sealing ring 70 is provided between the inner wall of the extension cover 101 and the outer wall of the plastic food processor cover 20. When assembling the extension cover 101 and the plastic food processor cover 20, the two need to be interlocked until the extension cover 101 abuts against the protrusion 201 of the plastic food processor cover 20. The abutment between the two serves as a limiting action.

[0041] See Figure 1 The blade shaft 30 is rotatably connected to a first connector 310 and a second connector 320; when the blade shaft 30 moves along the axis, the first connector 310 and the second connector 320 move synchronously; the food processor body 10 is provided with a mating part 330; the first connector 310 or the second connector 320 can abut and limit the movement with the mating part 330.

[0042] Furthermore, one end of the elastic element 300 abuts against the first connector 310, and the other end abuts against the food processor body 10.

[0043] Furthermore, both the first connector 310 and the second connector 320 are bearings.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
