Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, specifically relating to a juice cup and a juicer. Background Technology

[0002] Portable juicers allow for juicing anytime, anywhere, meeting juicing needs in various situations. Existing juicers incorporate a magnetic induction switch between the cup and lid to detect whether the lid is closed correctly. This switch typically consists of a sensor on the lid and a magnet on the cup. Utilizing the Hall effect sensing principle, the juicing function is activated only after the sensor and magnet are aligned, ensuring better safety.

[0003] To install the magnet into the juice cup, a mounting slot is typically created at a designated location on the juice cup, and then the individual magnet is snapped into the slot. However, due to the small size of the magnet, it is difficult for assemblers to grasp it and insert it into the mounting slot, resulting in a long assembly time and affecting the overall production cycle of the juicer. Utility Model Content

[0004] This utility model provides a juice cup and a juicer, aiming to solve the problem of the difficulty in installing the magnetic body on existing juice cups.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, embodiments of the present invention provide a juice cup, comprising:

[0007] The cup body has a mounting groove on the outer periphery of the rim.

[0008] A magnetic block is integrally injection molded with one edge of the opening end face of the mounting groove. The magnetic block has the freedom to swing toward the opening end face of the mounting groove, and the magnetic block can be inserted and mated with the mounting groove.

[0009] In conjunction with the first aspect, in one possible implementation, the magnetic block includes a magnetic core and a weld layer surrounding the core, the weld layer being capable of ultrasonic welding to the cup body.

[0010] In conjunction with the first aspect, in one possible implementation, the magnetic block has an exposed surface and multiple side surfaces. After the magnetic block is inserted into the mounting groove, the exposed surface covers the opening of the mounting groove, the side surfaces are in close contact with the inner sidewall of the mounting groove, and the draft angle of the side surfaces is 65°~75°.

[0011] In some embodiments, the intersection area of ​​the side panel and the exposed surface is integrally injection molded with the opening end face of the mounting groove.

[0012] In some embodiments, a first weakening groove is provided between the cup body and the magnetic block, and the opening direction of the first weakening groove is opposite to that of the mounting groove.

[0013] In some embodiments, a second weakening groove is provided between the cup body and the magnetic block, and the opening direction of the second weakening groove faces the mounting groove.

[0014] In conjunction with the first aspect, in one possible implementation, the depth of the mounting groove is D, the height of the magnetic block is H, and the relationship between D and H is: D > H.

[0015] In conjunction with the first aspect, in one possible implementation, the cup body has an outer ring plate and an inner mounting plate at the rim, the inner mounting plate is connected to the inner side of the outer ring plate, and the mounting groove is formed between the inner mounting plate and the outer ring plate. The magnetic block is integrally injection molded with the inner mounting plate.

[0016] In some embodiments, the thickness of the mounting inner plate is less than the thickness of the outer ring plate of the cup opening.

[0017] Compared with the prior art, the solution shown in this application involves integrally injection molding the cup body and the magnetic block during manufacturing. After injection molding, the magnetic block is located outside the mounting slot. Subsequently, the operator moves the magnetic block to gradually align it with the mounting slot until it is inserted into the mounting slot to complete the initial installation. This application eliminates the need for operators to separately grasp the magnetic block. Furthermore, because the magnetic block is positioned close to the mounting slot after molding, it is easier to align the magnetic block with the mounting slot. Therefore, the assembly process of the magnetic block and the cup body is simpler, the operational difficulty is greatly reduced, and the production efficiency of the juice cup is improved. The development of two separate parts is transformed into the development of a single integrated part, saving production costs. In addition, since the magnetic block and the cup body are integrally injection molded, the risk of losing this small part is effectively reduced, avoiding waste of parts.

[0018] Secondly, this utility model embodiment also provides a juicer, including the juice cup described above.

[0019] Compared with the prior art, the solution shown in this application significantly improves the filling efficiency of the juice cup by adopting the above-mentioned juice cup, thereby improving the overall production efficiency of the juicer, saving more manpower and material resources, and reducing production costs.

[0030] In the claims, description and accompanying drawings of this utility model, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0031] Please refer to the following: Figures 1 to 4 The juice cup provided by this utility model will now be described. The juice cup includes a cup body 1 and a magnetic block 2; the outer periphery of the cup mouth 101 of the cup body 1 is provided with a mounting groove 3; one side edge of the magnetic block 2 is integrally injection molded with the opening end face of the mounting groove 3, the magnetic block 2 has the freedom to swing toward the opening end face of the mounting groove 3, and the magnetic block 2 can be inserted and matched with the mounting groove 3.

[0032] Compared with the prior art, the juice cup provided in this embodiment is manufactured by integrally injection molding the cup body 1 and the magnetic block 2. After injection molding, the magnetic block 2 is located outside the mounting slot. Subsequently, the operator moves the magnetic block 2 to gradually align it with the mounting slot 3 until it is inserted into the mounting slot 3 to complete the initial installation. This embodiment eliminates the need for the operator to separately grasp the magnetic block 2. At the same time, since the magnetic block 2 is positioned close to the mounting slot 3 after molding, it is easier for the magnetic block 2 to be aligned with the mounting slot 3. Therefore, the assembly process of the magnetic block 2 and the cup body 1 is simpler, the operation difficulty is greatly reduced, and the production efficiency of the juice cup is improved. It changes the development of two parts separately into the development of a single part, saving production costs. In addition, since the magnetic block 2 and the cup body 1 are integrally injection molded, the risk of losing such a small part as the magnetic block 2 is also effectively reduced, avoiding waste of parts.

[0033] In some embodiments, see Figures 2 to 3The magnetic block 2 includes a magnetic core 210 and a weld layer 220 wrapped around the core 210. The weld layer 220 can be ultrasonically welded to the cup body 1, wherein the weld layer 220 covers each surface of the core 210. Ultrasonic welding utilizes the frictional heat generated by high-frequency vibration to locally heat and melt the material, which is then cooled and solidified under pressure to achieve welding. It offers the following advantages: First, it can complete the welding process in fractions of a second, significantly improving production efficiency. Second, it eliminates the need for auxiliary tools such as glue or screws, making it more energy-efficient and environmentally friendly. Third, it does not transmit current to the workpiece or introduce high-temperature heat sources during welding, avoiding defects such as microscopic pores and resulting in high static load strength, fatigue strength, and good stability of the weld joint. Fourth, it eliminates the need for water cooling and gas protection during welding, and the workpiece does not require annealing or other heat treatments after welding. The weld surface is clean and aesthetically pleasing, and there is no pollution from welding slag, wastewater, or harmful gases. Fifth, the welding equipment consumes very little power, only about 5% of that used in resistance spot welding, with weld deformation less than 3% to 5%, and an average increase in weld strength and strength stability of about 15% to 20%. Sixth, it does not damage the workpiece during welding, saving materials and costs. It is evident that ultrasonic welding can fully adapt to the welding method of fixing the magnetic block 2 to the cup body 1. After welding, the sealing performance of the opening area of ​​the mounting groove 3 is effectively guaranteed. While fully wrapping the core 210, it can also effectively prevent the magnetic block 2 from falling off.

[0034] To meet the requirements of ultrasonic welding and food-grade applications, the cup body 1 (including the outer ring plate 110 at the cup rim and the inner mounting plate 120) is made of plastic, such as polypropylene (PP), polystyrene (PS), or polycarbonate (PC). Alternatively, the cup body 1 (including the outer ring plate 110 at the cup rim and the inner mounting plate 120) can be made of glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP). Under ultrasonic vibration, the molecular structure of these materials rearranges, forming a strong welded joint. The material of the weld layer 220 is similar to that of the cup body 1; it can be the same material as the cup body 1 or a different material, as long as it meets the requirements of ultrasonic welding. There is no single limitation here.

[0035] It should be noted that after ultrasonic welding, the weld layer 220 undergoes melting deformation, and the connection 6 between the weld layer 220 and the cup body 1 also undergoes melting deformation, resulting in a relatively flat opening end face of the mounting groove 3.

[0036] Optionally, the core 210 can be made of neodymium iron boron magnets, which have high energy product and good temperature stability, making them suitable for applications requiring strong magnetic forces. Of course, the core 210 can also be made of other magnet materials; this is not a limitation.

[0037] In some embodiments, see Figure 3The magnetic block 2 has an exposed surface 201 and multiple side surfaces 202. After the magnetic block 2 is inserted into the mounting groove 3, the exposed surface 201 covers the opening of the mounting groove 3, and the side surfaces 202 are in close contact with the inner sidewall of the mounting groove 3. The draft angle B of the side surfaces 202 is 65°~75°. The draft angle, also known as the demolding angle, refers to the angle required for the plastic part to be removed from the mold in the product design. The draft angle is the angle between the tangential direction of the side surface where the workpiece intersects the mold parting surface and the normal direction of the mold parting surface, which is artificially set to allow the workpiece to be removed from the mold better. Its function is to ensure that the product can be smoothly removed from the mold and avoid demolding difficulties caused by friction or adsorption, thereby affecting product quality and production efficiency. The demolding process includes forced demolding. Forced demolding can reduce product deformation and mold wear caused by poor demolding, thereby improving the overall molding quality. It needs to be precisely controlled according to the characteristics of the mold and the product. The demolding angle can be optimized by increasing the demolding force, finely adjusting the demolding mechanism, or applying a demolding agent. This embodiment reasonably sets the draft angle to avoid mold ejection interference and achieve forced demolding. In specific implementation, the draft angle B of the side panel 202 can be selected as 68°, 70°, 73°, etc.

[0038] It should be noted that in this embodiment, the draft angle B of each side surface 202 is 65°~75°. This embodiment exemplarily shows a magnetic block 2 with four side surfaces 202. When not assembled with the mounting groove 3, the magnetic block 2 has a quadrangular pyramid structure with a smaller inner surface 203 and a larger exposed surface 201.

[0039] In some embodiments, see Figure 2 and Figure 3 The intersection area of ​​the side surface 202 and the exposed surface 201 is integrally injection molded with the opening end face of the mounting groove 3. In this way, the magnetic block 2 is closer to the mounting groove 3, making it easier to align with the mounting groove 3. At the same time, the magnetic block 2 can gradually move closer to the mounting groove 3 by simply swinging, avoiding the problem of twisting and breaking of the connection area between the magnetic block 2 and the cup body 1, and ensuring that the magnetic block 2 maintains an effective connection with the cup body 1 at all times while it is inserted into the mounting groove 3.

[0040] In some embodiments, see Figure 2 and Figure 3 The magnetic block 2 also has an inner surface 203 opposite to the exposed surface 201, and the inner surface 203 is a curved surface that protrudes away from the exposed surface 201.

[0041] In some embodiments, see Figure 2 and Figure 3A first weakening groove 4 is provided between the cup body 1 and the magnetic block 2. The opening direction of the first weakening groove 4 is opposite to that of the mounting groove 3. This allows the magnetic block 2 to swing towards the mounting groove 3, avoiding the problem that the connection area between the magnetic block 2 and the cup body 1 is too strong, making it difficult for the magnetic block 2 to move or even causing the connection area to break. Optionally, the first weakening groove 4 is a stepped groove, with one side wall flush with the exposed surface 201 of the magnetic block 2, which is simple in structure and saves materials.

[0042] Based on the above embodiments, see Figure 2 and Figure 3 A second weakening groove 5 is provided between the cup body 1 and the magnetic block 2, and the opening direction of the second weakening groove 5 faces the mounting groove 3. The second weakening groove 5 is provided on the basis of the first weakening groove 4 to further weaken the strength of the connection area, making it easier to move the magnetic block 2; in addition, the side wall of the second weakening groove 5 can also play a role in avoiding the magnetic block 2 when it is inserted, making it easier to insert the magnetic block 2.

[0043] Optionally, to facilitate the swinging of the magnetic block 2, a connecting part 6 is provided between the magnetic block 2 and the cup body 1. The cup body 1, the connecting part 6, and the magnetic block 2 are integrally injection molded. The thickness of the connecting part 6 is relatively small to accommodate the setting of the first weakening groove 4 and the second weakening groove 5, while reducing material usage.

[0044] In some embodiments, see Figure 3 The depth of the mounting groove 3 is D, and the height of the magnetic block 2 is H. The relationship between D and H is: D > H. By setting the depth of the mounting groove 3 to be greater, the weld layer 220 will deform during ultrasonic welding between the weld layer 220 and the cup body 1. The deeper mounting groove 3 can allow the weld layer 220 to flow and deform.

[0045] In some embodiments, see Figures 2 to 4 The cup body 1 has an outer ring plate 110 and an inner mounting plate 120 at the cup opening 101. The inner mounting plate 120 is connected to the inner side of the outer ring plate 110, and a mounting groove 3 is formed between the inner mounting plate 120 and the outer ring plate 110. The magnetic block 2 is integrally injection molded with the inner mounting plate 120. The outer ring plate 110 is used to connect with the cup lid. The mounting groove 3 is formed by setting the inner mounting plate 120. The inner mounting plate 120 is a plate designed for a single mounting groove 3, and its setting position is more targeted. In this embodiment, the structure forming the mounting groove 3 is simpler and the functional integration is higher, making the overall structure of the juice cup simpler.

[0046] Based on the above embodiment, the thickness of the inner mounting plate 120 is less than the thickness of the outer ring plate 110 of the cup opening. The outer ring plate 110 of the cup opening is made thicker to facilitate connection with the cup lid and to prevent cracking at the cup opening 101 after repeated opening and closing of the cup lid; at the same time, the inner mounting plate 120 is made thinner to meet the installation requirements of the magnetic block 2, and can also reduce the amount of material used and reduce production costs.

[0047] In some embodiments, see Figure 1 Multiple magnetic blocks 2 are arranged around the circumference of the cup opening 101 to meet the requirements of the juicer's sensing function. Correspondingly, multiple mounting inner plates 120 are arranged around the circumference of the cup opening 101, and the number of mounting slots 3 corresponds one-to-one. This embodiment exemplarily shows an example in which two mounting inner plates 120 are evenly arranged around the circumference of the cup opening 101, and two mounting slots 3 are formed accordingly.

[0048] Based on the same inventive concept, this application also provides a juicer, including the juice cup described above.

[0049] The juicer in this embodiment also includes a lid, which is equipped with a control switch, juicing blades, and a sensor corresponding to the magnetic block 2. After the lid is closed, if the sensor is aligned with the magnetic block 2, pressing the control switch will initiate the juicing operation; if the sensor is not aligned with the magnetic block 2, pressing the control switch will not initiate the juicing operation; if the lid is loosened after juicing, the sensor and magnetic block 2 will be misaligned, and the juicing function cannot be triggered again. The lid and the juice cup can be connected by threads or by a rotating snap-fit ​​mechanism.

[0050] Compared with the prior art, the juicer provided in this embodiment significantly improves the assembly efficiency of the juice cup by adopting the above-mentioned juice cup, thereby improving the overall production efficiency of the juicer, saving more manpower and material resources, and reducing production costs.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
