Description

Technical Field

[0001] This utility model relates to the field of juicers, and in particular to a portable juicer. Background Technology

[0002] The liquid-holding chambers in existing juicers are mostly made of plastic. The microporous nature of the plastic surface easily absorbs food pigments and forms stubborn stains, especially after processing dark fruits, making it difficult to clean thoroughly and restore the original appearance, which seriously affects the aesthetics. At the same time, plastic is prone to mold growth or residual organic odors in humid environments. After repeated use, mold spots can accumulate in the gaps around the blades or in the scratches on the inner wall, posing a hygiene and safety hazard. In addition, the plastic inner wall is inefficient at cleaning sticky fruit pulp fibers or small seeds, requiring repeated scrubbing with tools and easily leaving dirt in hard-to-reach areas, resulting in a poor user experience. These material defects have led to traditional juicers facing problems such as staining, mold, and incomplete cleaning for a long time. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a portable juicer, which overcomes the technical drawbacks of plastic bases, such as difficulty in cleaning stains, high-temperature deformation, and surface wear, by designing the area of ​​the inner wall of the housing cavity of the base to be made of metal.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0035] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] The following is a reference to the appendix. Figure 1 To be continued Figure 8 The portable juicer 10 described in some embodiments of the present invention is described below.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present invention provides a portable juicer 10, including a cup body 100 and a base 200.

[0039] The cup body 100 and the base 200 are detachably connected and together define the receiving cavity 300. The base 200 and the cup body 100 can be connected by snap-fit, threaded connection, magnetic connection, tight fit, etc., which will not be listed here.

[0040] In one embodiment, the cup body 100 has an opening, and the base 200 is detachably connected to the cup body 100 and seals the opening of the cup body 100, so that the cup body 100 and the base 200 together enclose a receiving cavity 300 for holding food or liquid. More specifically, the base 200 can be placed on the cup body 100 as a lid. When juicing, the base 200 is positioned below the cup body 100 to achieve juicing. When pouring beverages, the cup body 100 is placed below the base 200, and the base 200 is detached from the cup body 100 so that the beverage can be poured out from the opening. This makes the product have fewer parts and is more portable. Alternatively, the cup body 100 can be designed with openings at both ends, and the base 200 can seal one of the openings. The portable juicer 10 also includes a lid that is detachably placed on the cup body 100 and can seal the other opening.

[0041] Of course, the above are only some possible implementation methods of this utility model. Those skilled in the art can also design the assembly method of the cup body 100 and the base 200 according to actual needs. For example, the base 200 and the peripheral side wall 2203 of the cup body 100 can be designed to be detachably connected.

[0042] The base 200 is equipped with a blade 400 and a drive unit 500 for driving the blade 400. The blade 400 is mounted on the base 200, and the drive unit 500 is built into the base 200. The drive unit 500 is connected to the blade 400 to drive the blade 400 to rotate, thereby cutting and stirring the food. When the base 200 is connected to the cup body 100, the blade 400 is located in the receiving cavity 300. More specifically, the blade 400 includes multiple blades. By driving the blade 400 to rotate at high speed, the food is crushed to achieve juicing. When the base 200 and the cup body 100 are disassembled, the blade 400 is exposed, making it easier for users to wipe and clean the cup body 100, the base 200, and the blade 400 on the base 200, reducing cleaning dead spots and improving the user experience.

[0043] At least the area forming the inner wall of the receiving cavity 300 on the outer surface of the base 200 is made of metal. By making the area of ​​the base 200 forming the inner wall of the receiving cavity 300 a metal material (such as stainless steel, iron, iron alloy, etc.), compared with traditional plastic structures or structures with non-stick coatings, the metal material has the characteristics of a dense and non-porous surface, which can completely block the penetration of fruit and vegetable pigments, avoid permanent staining caused by dark-colored ingredients such as dragon fruit and carrots, and also prevent juice residue from adhering, making it easy to clean with a simple wipe, significantly improving the user experience. At the same time, the metal material can withstand the local temperature rise generated by high-speed juicing, effectively avoiding problems such as sealing failure and cracking caused by deformation. Furthermore, the high hardness of the metal surface can effectively resist the friction of fruit residue splashed during the operation of the blades 400, avoiding the accumulation of dirt and grime due to micropores and scratches caused by wear.

[0044] The specific structural design of the base 200 is described in detail below.

[0045] In one possible implementation, such as Figure 3 and Figure 5 As shown, the design base 200 includes a base 220 and a metal part 210. The base 220 is made of a non-metallic material and has a mounting cavity 2201, within which the drive component 500 is located. For example, the base 220 can be made of plastic, silicone, rubber, etc., which will not be listed here. At least a portion of the outer surface of the base 220 is attached to the metal part 210, and the outer surface of at least a portion of the metal part 210, together with the cup body 100, forms the inner wall surface of the receiving cavity 300.

[0046] Understandably, the metal part 210 has problems such as large weight, complicated processing and plasticization process, and high cost. In this embodiment, the base 220 is used as the main component of the base 200. The mounting cavity 2201 inside it can support the drive component 500, electrical control components and other parts. The metal part 210 is attached to the inner wall of the base 220 to form the receiving cavity 300, which not only avoids the staining problem caused by dark-colored food such as dragon fruit and carrots, but also achieves lightweight design.

[0047] Preferably, the metal part 210 and the base 220 are integrally connected, that is, the metal part 210 and the base 220 are designed as an integral structure that cannot be disassembled, so that the connection between the metal part 210 and the base 220 is tighter and liquid is less likely to penetrate.

[0048] Of course, in other embodiments, the metal part 210 and the base 220 can be designed to be detachably connected, so that the metal part 210 can be replaced.

[0049] Furthermore, such as Figure 5 and Figure 8 As shown, the cup body 100 includes a cup opening 110, and the portion of the base 220 corresponding to the mounting cavity 2201 extends into the cup body 100 from the cup opening 110. The portion of the base 220 corresponding to the mounting cavity 2201 has a top wall 2202 and a peripheral side wall 2203. The metal part 210 is attached to the top wall 2202 and extends from the top wall 2202 to cover the peripheral side wall 2203.

[0050] In this embodiment, the portion of the base 220 corresponding to the mounting cavity 2201 extends from the cup opening 110 into the cup body 100, effectively utilizing the redundant space within the cup body 100. This significantly reduces the overall structural height of the juicer, making it more compact and lower, improving portability and making it easier to store and carry. Simultaneously, the metal part 210 completely covers the top wall 2202 and peripheral sidewalls 2203 of the extended portion of the base 220, ensuring a smooth, flat, and seamless outer surface. Food residue and juice are less likely to remain on the surface of the metal part 210, making it easier to clean. Simple rinsing and wiping are sufficient to maintain hygiene, avoiding the staining, absorption, or difficult-to-clean dead corners that may exist with traditional materials, thus improving user experience and maintenance convenience.

[0051] Furthermore, such as Figure 3 As shown, the peripheral sidewall 2203 is adapted to the inner sidewall of the cup body 100. This, on the one hand, expands the radial dimension of the base 220, thereby increasing the capacity of the mounting cavity 2201, allowing it to more fully accommodate the drive component 500 and related electronic control components, improving the layout freedom and load-bearing capacity of internal parts, and ensuring the necessary space for stable operation of the drive system. On the other hand, the portion of the base 220 extending into the cup body 100 blocks the cup opening 110, effectively preventing food juices from leaking upwards from the potential gaps at the junction of the cup body 100 and the base 200. The non-splashing design significantly improves the overall sealing performance and leakage prevention safety during use. Simultaneously, the portion of the metal part 210 attached to the top wall 2202 and the inner wall of the cup body 100 together form the inner wall of the receiving cavity 300. The portion of the metal part 210 attached to the peripheral side wall 2203 contacts the inner wall of the cup body 100. The portion of the metal part 210 attached to the top wall 2202 is primarily in contact with the liquid, while the portion attached to the peripheral side wall 2203 is almost entirely free from liquid contact. This further reduces the cleaning area required after each use, enhancing user experience and maintenance convenience.

[0052] Furthermore, the end of the peripheral sidewall 2203 furthest from the top wall 2202 is fused or welded to the metal part 210. By designing the base 220 and the metal part 210 to be fixed by fusion or welding, the structural integrity and long-term reliability of the machine base 200 are significantly improved. The fusion or welding forms a strong bonding surface between the metal part 210 and the base 220, making the base 220 and the metal part 210 tightly bonded into a rigid integral structure. This effectively resists the vibration and impact generated by the high-speed rotation of the tool 400 and the mechanical stress caused by frequent disassembly and assembly, preventing the metal part 210 and the base 220 from loosening, deforming or separating due to differences in the thermal expansion coefficients of the materials or external forces. This ensures that the metal part 210 is always firmly attached to the surface of the base 220, avoiding the possibility of the metal part 210 edge lifting or gaps.

[0053] Better, such as Figure 6 and Figure 7 As shown, the portable juicer 10 also includes a sealing ring 600. The base 220 and the metal part 210 are respectively provided with through holes 700. The sealing ring 600 is located between the base 220 and the metal part 210 and is positioned opposite to the through holes 700. The output shaft of the drive unit 500 passes through the two through holes 700 and the sealing ring 600 and is connected to the blade 400.

[0054] By adding a sealing ring 600 located between the base 220 and the through hole 700 of the metal part 210, and ensuring that the output shaft of the drive component 500 simultaneously passes through both through holes 700 and the sealing ring 600 to connect to the cutter 400, a key dynamic sealing barrier for the rotating output shaft is constructed. The sealing ring 600 is tightly pressed between the mating surfaces of the base 220 and the metal part 210 during assembly. During juicing, the high-speed rotating cutter 400 within the receiving cavity 300 subjectes the juice to significant centrifugal force and splash pressure, preventing the juice from penetrating along the output shaft surface to the interface between the base 220 and the metal part 210. This avoids the risk of juice seeping into the internal mounting cavity 2201 through the gap in the through hole 700, and prevents short circuits, corrosion, or functional failures of the drive component 500 and electrical control components due to moisture or liquid intrusion, significantly improving the overall electrical safety and long-term operational reliability of the machine.

[0055] Furthermore, either or both of the substrate 220 and the metal part 210 are configured to have a gap 800 for accommodating the sealing ring 600. By designing a gap 800 in the base 220 and the metal part 210 to accommodate the sealing ring 600, the gap 800 provides a stable and dimensionally matched accommodating space for the sealing ring 600. This allows it to be precisely confined to a predetermined position around the through hole 700 during assembly, preventing sealing failure due to misalignment or displacement. Simultaneously, the depth and shape of the gap 800 allow the sealing ring 600 to undergo sufficient elastic deformation to fill the gap under axial pressure, forming a uniform pressure ring around the output shaft. This ensures a continuous and stable barrier against liquid penetration under dynamic rotation. Furthermore, by locally setting the gap 800 in the through hole 700, the tight fit between the base 220 and the remaining contact surfaces of the metal part 210 is ensured. This results in a large-area, gapless fit between the metal part 210 and the base 220 in the non-sealing area, significantly enhancing the overall structural strength and deformation resistance of the machine base 200's extended portion. This effectively resists vibration and impact during the operation of the tool 400, preventing damage to the effective pressing state of the sealing ring 600 due to micro-displacement of components.

[0056] In one possible implementation, the base 220 includes an upper seat 221 and a lower seat 222. The upper seat 221 is configured as a cavity structure with an opening 2211 at one end. The metal part 210 is attached to the outer surface of the cavity structure. The lower seat 222 is connected to the upper seat 221 and together with the upper seat 221 defines the mounting cavity 2201.

[0057] By designing the base 220 as a split structure of upper seat 221 and lower seat 222, the manufacturing and assembly process is optimized and the structural reliability is improved. Specifically, the upper seat 221 adopts a concave cavity structure with one end open 2211, which provides a precise attachment surface for the metal part 210, ensuring that the metal part 210 can tightly cover the outer surface of the concave cavity and form a smooth metal interface on the inner wall of the receiving cavity 300. The lower seat 222, through a detachable connection with the upper seat 221, together encloses a complete mounting cavity 2201. This not only greatly simplifies the layout and assembly process of internal components and improves production efficiency, but also provides convenience for later maintenance or component replacement. If the drive component 500 fails, it can be repaired by simply disassembling the lower seat 222, thus extending the service life of the whole machine.

[0058] Furthermore, the upper seat 221 also has an annular wall 2112 constructed on the outer periphery of the cavity structure. The annular wall 2112 is spaced apart from and transitionally connected to the cavity structure. The annular wall 2112 and the cavity structure together define an insertion groove 2113. The cup body 100 extends into the insertion groove 2113 and connects with the insertion groove 2113. The insertion groove 2113 provides precise positioning for the cup body 100, improves the connection reliability between the cup body 100 and the base 200, and prevents the cup body 100 from shaking or shifting.

[0059] In another specific embodiment, the base 200 is designed to include a base 220 and a metal part 210, wherein the base 220 is made of non-metallic material, the base 220 and the metal part 210 together define a mounting cavity 2201, the drive member 500 is located in the mounting cavity 2201, and at least part of the outer surface of the metal part 210 together with the cup body 100 forms the inner wall surface of the receiving cavity 300. The difference between this embodiment and the previous embodiment is that the mounting cavity 2201 is formed by the base 220 and the metal part 210. For example, the metal part 210 and the base 220 are designed to be detachably connected, and one of them is constructed as a concave cavity structure with an opening 2211 at one end. When the metal part 210 is assembled with the base 220, the opening 2211 is sealed and the mounting cavity 2201 is formed. Of course, it is also possible to design both the metal part 210 and the base 220 as concave cavity structures with an opening 2211 at one end, and the two concave cavity structures are combined to form the mounting cavity 2201. This also avoids the staining problem caused by dark-colored foods such as dragon fruit and carrots, and achieves a lightweight design.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
