[0001] The utility model relates to the technical field of juice extractors, in particular to a sealing structure of a juice extractor. Background Art
[0002] With the increasing improvement of people's living standards, many different types of cooking machines have emerged on the market. The cooking machine can perform functions such as making soy milk, squeezing juice, making rice paste, mincing meat, making shaved ice, making coffee, and / or preparing facial masks. At present, the cup bodies of cooking machines on the market are all blow-molded, and the screw threads are all arranged on the outer side of the cup mouth, and are screwed tightly with the internal threads of the knife holder. The knife holder sealing ring is arranged on the inner side of the knife holder. If the sealing ring is not installed in place or becomes loose during work, it is easy to be shredded by the knife; and during the working process of the cooking machine, since the blade and the material are in the same sealed environment, the material will expand during the crushing process, and the pressure in the cup cannot be released, resulting in the sealing ring shrinking after cooling, and the liquid flowing out from the gaps between the cup body and the knife holder; or when crushing ice cubes, the pressure in the cup will also decrease, resulting in the sealing ring shrinking, and the liquid flowing out from the gaps between the cup body and the knife holder. Therefore, a sealing structure of a juice extractor is proposed to solve the above problems. Content of the Utility Model
[0003] To overcome the above technical defects, the utility model provides a sealing structure of a juice extractor, which is characterized in that through innovative design, the stable installation of the sealing ring is realized, the internal pressure change during work is effectively dealt with, and the waterproof, dustproof and operation performance of the button are optimized. The specific technical points are as follows: including a knife holder, a cup body, a cover plate, a button module and an elastic first sealing ring. The cup body is sleeved on the knife holder. The first sealing ring is installed on the top of the knife holder. The bottom of the first sealing ring bulges inward to form a horizontal convex ring and catches the first groove on the outer side of the knife holder. The middle part of the first sealing ring is hollow to form a clamping groove and wraps the convex piece at the top of the knife holder. The inner side of the top of the first sealing ring bulges downward to form a vertical convex ring, and the bottom of the vertical convex ring abuts and fits against the reflux surface on the inner side of the knife holder. The clamping groove is higher than the convex piece to form a deformable cavity; the cover plate is welded and fixed to the bottom of the knife holder, and the button module is sealed and installed on the cover plate. This technical solution designs a cavity between the sealing ring and the knife holder. When the pressure between the knife holder and the cup body is too high, the sealing ring deforms to realize automatic pressure relief and prevent a gap from being formed between the sealing ring and the cup body.
[0004] Further, the distance between the top of the clamping groove and the convex piece is 3-10 mm.
[0005] Further, a cavity is opened in the first sealing ring.
[0006] More preferably, the cross section of the cavity is in the shape of "7" and wraps the top and the inner side of the clamping groove, and the cavity is communicated with the outside through a through hole.
[0007] Optionally, the bottom of the cup body is snap-connected to the bottom of the knife holder through a snap, and the cup body and the knife holder are conical. The reflux surface is inclined and gradually increases from the inside to the outside.
[0008] For a further description of the foregoing solution, the key module includes a key, and the key is connected to the device circuit; an elastic seal, which is located between the key and the cover plate of the device and is used to isolate the key from the outside of the device. The elastic seal is provided with corresponding convex columns at the position of the key to improve its resilience, and the elastic seal is provided with a convex ring at the joint surface with the cover plate; a key panel, which is fixedly installed between the elastic seal and the cover plate of the device, and the center of the key panel protrudes and passes through the key hole of the cover plate; a second sealing ring, which wraps the peripheral edge of the elastic seal and the inverted ring protruding from the inside of the cover plate, so that the peripheral edge and the inverted ring are fitted, and presses the convex ring on the top surface of the elastic seal against the cover plate.
[0009] Further, a second groove is formed by concave downward in the center of the top of the elastic seal, and a plurality of downward-penetrating card holes are provided at the second groove. The key panel is provided with hooks corresponding to the card holes, and the key panel is fixed on the elastic seal through the hooks and the card holes, and the card holes tightly wrap the hooks.
[0010] Further, a concave column is provided at the center of the bottom of the key panel, and the concave column is sleeved on the convex column in the middle of the elastic seal.

[0030] To make the technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the drawings.
[0031] Please refer to Figure 1-12 As shown, the present application discloses a sealing structure of a juicer, including a knife holder 3, a cup body 1, a cover plate 8, a key module, and an elastic first sealing ring 2. The cup body 1 is sleeved on the knife holder 3. The first sealing ring 2 is installed on the top of the knife holder 3. The bottom of the first sealing ring 2 bulges inward to form a horizontal convex ring 22 and catches the outer first groove 31 of the knife holder 3. The middle of the first sealing ring 2 is hollow to form a clamping groove 21 and wraps the convex piece 32 at the top end of the knife holder 3. The inner side of the top of the first sealing ring 2 bulges downward to form a vertical convex ring 23, and the bottom of the vertical convex ring 23 is in abutting fit with the reflux surface 33 inside the knife holder 3. The clamping groove 21 is higher than the convex piece 32 to form a deformable cavity. The cover plate 8 is fixed to the bottom of the knife holder 3 by ultrasonic welding, and the key module is hermetically installed on the cover plate 8. This technical solution designs a cavity between the sealing ring and the knife holder 3. When the pressure between the knife holder 3 and the cup body is too high, the first sealing ring 2 deforms to achieve automatic pressure relief and prevent a gap from forming between the sealing ring and the cup body 1.
[0032] In this embodiment, the distance between the top of the card slot 21 and the tab 32 is 5 mm. In other technical solutions, the distance can be adjusted according to actual requirements. The bottom of the cup body 1 is snap-connected to the bottom of the knife holder 3, and the cup body 1 and the knife holder 3 are conical, which increases the contact area between the cup body 1 and the first sealing ring 2 and effectively improves the overall sealing performance.
[0033] As Figure 6 shown, in another embodiment, a cavity 24 is formed in the first sealing ring 2. The cross-section of the cavity 24 is in the shape of "7" and wraps the top and the inner side of the card slot 21. When the first sealing ring 2 deforms, the first sealing ring 2 further fills and seals the gap between the cup body 1 and the knife holder 3. The cavity 24 can also communicate with the outside through a through hole 25, and part of the gas can be discharged when the first sealing ring 2 deforms.
[0034] Optionally, the bottom of the cup body 1 is snap-connected to the bottom of the knife holder 3, and the cup body 1 and the knife holder 3 are conical. The reflux surface 33 is inclined and gradually increases from the inside to the outside.
[0035] As Figure 8-12 shown, the key module includes a key 4 which is connected to the device circuit; an elastic seal 5 which is located between the key 4 and the cover plate 8 of the device and is used to isolate the key 4 from the outside of the device. The elastic seal 5 is provided with corresponding convex columns 56 at the position of the key 4 to improve its resilience. The elastic seal 5 and the cover plate 8 are provided with a convex ring 54 at the joint surface; a key panel 6 which is fixedly installed between the elastic seal 5 and the cover plate 8 of the device, and the center of the key panel 6 protrudes and passes through the key 4 hole of the cover plate 8; a second sealing ring 7 which wraps the peripheral edge 55 of the elastic seal 5 and the inverted ring 82 protruding from the inside of the cover plate 8, so that the peripheral edge 55 and the inverted ring 82 are in contact, and presses the convex ring 54 on the top surface of the elastic seal 5 against the cover plate 8. The bottom of the key panel 6 protrudes outwards to form a flange 62, and the upper and lower surfaces of the flange 62 are respectively in contact with the inside of the cover plate 88 and the surface of the elastic seal 5.
[0036] Please refer to Figure 10 , a second groove 53 is formed in the center of the top of the elastic seal 5, and a plurality of downward-penetrating card holes 52 are provided at the second groove 53. The key panel 6 is provided with barbs 63 corresponding to the card holes 52. The key panel 6 is fixed on the elastic seal 5 through the barbs 63 and the card holes 52, and the card holes 52 tightly wrap the barbs 63. As Figure 12 shown, a cavity 51 is provided in the center of the bottom of the elastic seal 5 to wrap the key 4. A concave column 61 is provided in the center of the bottom of the key panel 6, and the concave column 61 is sleeved on the convex column 56 in the middle of the elastic seal 5.
[0037] As Figure 10 、 12As shown, the cross-section of the second sealing ring 7 is concave. The second sealing ring 7 wraps and fits the surrounding edge 55 and the inverted ring 82 through the concave part. Moreover, triangular convex cones 71 are provided at the outer top of the second sealing ring 7 and the bottom of the inverted ring 82 to further isolate water vapor. Both the elastic sealing member 5 and the second sealing ring 7 are made of silica gel material, and both the elastic sealing member 5 and the key panel 6 are light-transmissive. The top of the key panel 6 is recessed to form an arc, and key markings are provided on the top surface of the key panel 6.
[0038] In order to understand the disclosed content of the present utility model more thoroughly and comprehensively, its principle will be further explained below in combination with the usage method.
[0039] During actual use, first put materials such as fruits to be juiced into the cup body 1, then install the cutter base 3 on the cup body 1, and then invert or tilt it. During the working process of the juicer, the pressure inside the cup body 1 increases. As Figure 5 shown, since there is a cavity between the first sealing ring 2 and the convex piece 32 at the top of the cutter base 3, the first sealing ring 2 can be easily deformed. After deformation, the first sealing ring 2 will fit more closely to the cup body 1 and the cutter base 3, improving the sealing effect. After the first sealing ring 2 returns to its original shape, there will be no gap between the fitting surfaces of the first sealing ring 2 with the cup body 1 and the cutter base 3, and the liquid in the cup cannot invade, making it more convenient to clean and more hygienic and safe.
[0040] In the above solution, a cavity 24 can also be provided inside the first sealing ring 2. As Figure 6 shown, the first sealing ring 2 provided with this cavity 24 can generate greater deformation, and after deformation, the first sealing ring 2 will fit more closely to the cup body 1 and the cutter base 3, not only slowing down the pressure inside the cup but also further improving the overall sealing performance.
[0041] On the basis of the foregoing solution, as Figure 7 shown, the cavity 24 can also communicate with the outside through a through hole 25, and part of the gas can be discharged when the first sealing ring 2 deforms.
[0042] As Figure 10 、 12 shown, install the key 4, the elastic sealing member 5, the key panel 6, and the second sealing ring 7 to ensure that the components fit together. When the user presses down the key panel 6, the middle part of the elastic sealing member 5 and the key 4 move downward and accumulate elastic force. The signal of the key 4 is transmitted to the circuit board. At this time, release the key panel 6, and the elastic sealing member 5 and the key 4 rebound and reset at the same time. The key panel 6 hits the user's finger to give the user feedback on the state of the key 4. When the middle part of the elastic sealing member 5 and the key 4 move downward, the convex ring 54 of the elastic sealing member 5 still fits the inner side of the cover plate 8, and water vapor cannot invade. If the water vapor breaks through the convex ring 54, there are still the inverted ring 82 and the convex cone 71 to block it.
[0043] In summary, the sealing structure of the juicer of the present utility model significantly improves the stability and pressure resistance of the sealing ring, effectively preventing liquid leakage during operation. At the same time, the innovative button 4 structure design not only enhances the waterproof and dustproof performance, but also optimizes the user's operation experience, ensuring the safety and convenience of electrical appliance use, solving multiple problems in the prior art, and having high practical value and market application prospects.
[0044] Those skilled in the art will readily conceive of other embodiments of the present utility model after considering the specification and practicing the present utility model. This application is intended to cover any variations, uses, or adaptations of the present utility model, which follow the general principles of the present utility model and include well-known common general knowledge or conventional technical means in the technical field not disclosed in the present utility model. The specification and examples are only regarded as exemplary, and the true scope and spirit of the present utility model are pointed out by the following claims.
[0045] It should be understood that the present utility model is not limited to the exact structures already described and shown in the drawings, and various modifications and changes can be made without departing from its scope.
