Description

Technical Field

[0001] The invention belongs to the technical field of small household appliances, and in particular relates to an inflatable component, a pressing rod component and a juicer. Background Art

[0002] The juicers on the market currently squeeze out pure juice, which is purer, more natural, more nutritious and fresher than the various mixed juice drinks sold on the market. However, some juice drinks on the market are filled with gas, which makes them taste refreshing and spicy, and are loved by some consumers. The taste experience of pure juice squeezed by a juicer is greatly reduced compared with that of juice drinks filled with gas.

[0003] For example, a Chinese patent application with application publication number CN107259964A provides a juicer, including a material cover, a juice extraction barrel, a juice collection barrel, a screw and a filtering device, wherein the material cover is covered on the juice collection barrel. The juicer further filters the fruit squeezed by the screw by providing a filtering device. On the basis of satisfying the functions of squeezing and juice-residue separation, the filtering device performs secondary filtration of the juice, thereby enhancing the taste of the juice and facilitating user experience. However, the juicer cannot fill the juice collection barrel with gas, and the juice does not have a refreshing and spicy taste when drinking. Therefore, there is a need for an inflation component that can fill the juice cup of the juicer with gas. Summary of the invention

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present invention is to provide an inflation component which has a simple structure, is easy to use, can fill gas into the juice in the juice cup, and has a good inflation effect; and to provide a pressing rod assembly which has multiple functions and is easy to store, and also provides a juicer which can prepare juice filled with gas.

[0007] An inflation tube, a first end of which is connected to the lower end of the inflation seat, and a second end of the inflation tube forms an inflation port;

[0008] A puncture needle, which is arranged on the inflation seat and communicated with the first end of the inflation tube, and at least the needle head of the puncture needle extends into the chamber;

[0009] A compressed gas cylinder, which can be placed in the chamber, and the mouth of the compressed gas cylinder is opposite to the needle of the puncture needle;

[0010] An adjusting cover is adjustably arranged on the inflation seat to push the compressed gas cylinder toward the puncture needle so that the puncture needle punctures the compressed gas cylinder. The gas in the compressed gas cylinder enters the inflation tube through the puncture needle and is discharged from the inflation port of the inflation tube to inflate the inflatable component.

[0011] The inflation component of the embodiment of the present invention has a simple structure and convenient inflation operation, and can be applied to a juice cup to inflate the juice in the juice cup, so that the juice has a refreshing and spicy taste, thereby improving the user's drinking experience.

[0012] In some embodiments, the aperture of the first tube hole at the first end of the inflation tube is larger than the aperture of the second tube hole at the second end of the inflation tube, so that a step portion is formed between the two; a gas one-way valve is provided in the first tube hole to only allow gas to enter the second tube hole from the puncture needle. By providing the gas one-way valve, after the inflation is completed, the elastic member causes the valve core to immediately block the puncture needle, preventing the gas in the inflation tube from flowing upward, thereby effectively preventing the juice in the juice cup from flowing back.

[0047] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0048] An embodiment of the present invention provides an inflation component, which can be used to inflate gas into a container, for example, a juice cup containing juice, so that gas is fully mixed in the juice, thereby improving the taste of the juice and giving it a refreshing and spicy feeling when drinking.

[0049] like Figures 1 to 4As shown, the inflation component of the embodiment of the present invention includes an inflation seat 1, an inflation tube 2, a puncture needle 3, a compressed gas cylinder 4 and an adjustment cover 5. The inflatable seat 1 has a chamber 14 at least extending to the upper end of the inflatable seat 1; the first end of the inflatable tube 2 is connected to the lower end of the inflatable seat 1, and the second end of the inflatable tube 2 forms an inflating port 21; the puncture needle 3 is arranged on the inflatable seat 1 and communicated with the first end of the inflatable tube 2, and at least the needle head of the puncture needle 3 extends into the chamber 14; the compressed gas cylinder 4 can be arranged in the chamber 14, and the bottle mouth of the compressed gas cylinder 4 is opposite to the needle head of the puncture needle 3; the adjustment cover 5 is adjustably arranged on the inflatable seat 1, that is, the adjustment cover 5 can move on the inflatable seat 1 to change the position of the adjustment cover 5 relative to the inflatable seat 1, and when the adjustment cover 5 moves downward relative to the inflatable seat 1, it can push the compressed gas cylinder 4 to move toward the puncture needle 3, so that the bottle mouth of the compressed gas cylinder 4 is against the puncture needle 3, the puncture needle 3 punctures the compressed gas cylinder 4, and the gas in the compressed gas cylinder 4 enters the inflatable tube 2 through the puncture needle 3, and is discharged from the inflatable port 21 of the inflatable tube 2 to inflate the inflatable component.

[0050] The inflation component of the embodiment of the present invention has a simple structure and convenient inflation operation, and can be applied to a juice cup to inflate the juice in the juice cup, so that the juice has a refreshing and spicy taste, thereby improving the user's drinking experience.

[0051] In some embodiments, the combination Figures 1 to 3 The diameter of the first tube hole at the first end of the gas-filling tube 2 is larger than the diameter of the second tube hole at the second end of the gas-filling tube 2, so that a step portion is formed between the two; a gas check valve 6 is provided in the first tube hole to only allow gas to enter the second tube hole through the puncture needle 3. By providing the gas check valve 6, after the gas is filled, the gas in the gas-filling tube 2 can be prevented from flowing upward, thereby effectively preventing the liquid in the container (such as a juice cup) from flowing back through the gas-filling tube 2.

[0052] In some embodiments, Figures 1 to 4 As shown, the gas one-way valve 6 includes a valve core 61 and an elastic member 62, and the two ends of the elastic member 62 are respectively against the valve core 61 and the step portion to apply an elastic force to the valve core 61 so that the valve core 61 seals the tail end of the puncture needle 3. That is, in the absence of an external force, the valve core 61 maintains a state of blocking the tail end of the puncture needle 3, and the puncture needle 3 is isolated from the inside of the inflation tube 2. When the puncture needle 3 punctures the compressed gas cylinder 4, the gas in the compressed gas cylinder 4 enters the puncture needle 3 and acts on the valve core 61 to push the valve core 61 to overcome the elastic force of the elastic member 62 to make the valve core 61 detach from the tail end of the puncture needle 3, and the puncture needle 3 is connected to the inflation tube 2, and the gas in the compressed gas cylinder 4 enters the inflation tube 2 through the gas one-way valve 6. The specific structure of the elastic member 62 is not limited, for example, it can be a spring, which has a simple structure, is easy to obtain materials, and has a good elastic effect.

[0053] In some embodiments, in order to stabilize the valve core 61 and make the valve core 61 move smoothly in the first tube hole as the valve cavity, the gas one-way valve 6 also includes a valve core frame 63, the valve core 61 includes a head and a tail, the head has a spherical surface for sealing the tail end of the needle 3; the neck is connected between the head and the tail, so that an annular groove around the neck is formed between the head and the tail; the valve core frame 63 has an inner hole, the inner wall of the inner hole is provided with a protrusion along its circumference, the neck and the tail of the valve core 61 are arranged in the inner hole, and the protrusion is embedded in the annular groove, see Figures 1 to 4 One end of the spring as the elastic member 62 can be connected to the outer periphery of the valve core frame 63, and the other end of the spring is connected to the step portion. In this way, when the spring is compressed or released, the valve core frame 63 is pushed to drive the valve core 61 to move up and down smoothly in the first tube hole to block the puncture needle 3 or allow the gas in the puncture needle 3 to be released to the second tube hole.

[0054] Continue to combine Figures 1 to 4 , the lower end of the inflatable seat 1 is provided with an installation cavity, and the inner wall of the installation cavity is provided with an internal thread 13; the outer wall of the first end of the inflatable tube 2 is provided with an external thread 92, and the first end of the inflatable tube 2 is threadedly connected to the installation cavity. To facilitate the disassembly and assembly of the inflatable tube 2 and the inflatable seat 1, and to facilitate product maintenance. The cross-sectional shape of the installation cavity can be circular to facilitate threaded connection. A sealing ring 64 is provided between the inflatable tube 2 and the inflatable seat 1 to prevent gas leakage. At the same time, it can also prevent the liquid in the container to be inflated from entering the inflatable tube 2 and affecting the inflation efficiency. There can be two sealing rings 64, and the two sealing rings 64 are respectively arranged between the inflatable tube 2 and the upper and lower ends of the cavity wall of the installation cavity. Specifically, the sealing ring 64 at the upper end is located between the end face of the first end of the inflatable tube 2 and the cavity bottom wall of the installation cavity (the cavity wall facing the cavity opening is defined as the cavity bottom wall). Such a setting can further improve the sealing effect.

[0055] Continue to combine Figures 1 to 3 The needle 3 is arranged in the inflation seat 1 between the chamber 14 and the installation chamber, and the needle head of the needle 3 extends into the chamber 14. The tail end of the needle 3 is connected to the first end of the inflation tube 2 through the air hole 31. That is, the inflation seat 1 is provided with an air hole 31 that connects the tail end of the needle 3 and the inflation tube 2. The lower end of the air hole 31 passes through the middle of the bottom of the installation chamber. The valve core 61 blocks the lower end of the air hole 31 to achieve the blocking of the tail end of the needle 3. In order to achieve the sealing fit between the valve core 61 and the air hole 31 in the middle of the bottom of the installation chamber, the head of the valve core 61 forms a spherical convex surface, and the middle surface of the bottom of the chamber forms a concave surface that matches the head of the valve core 61.

[0056] In some embodiments, in order to achieve the adjustment cover 5 to move up and down relative to the inflatable seat 1 so as to be able to push against the compressed gas cylinder 4, continue to combine Figures 1 to 3The inner wall of the regulating cover 5 is provided with an internal thread 13, and the upper end of the inflating seat 1 is provided with an external thread 92. The regulating cover 5 is threadedly connected to the inflating seat 1. When the regulating cover 5 is screwed into the inflating seat 1, it can push the compressed gas cylinder 4 toward the puncture needle 3 to puncture the compressed gas cylinder 4, so that the gas in the compressed gas cylinder 4 enters the inflating tube 2. The structure is simple, the adjustment is stable, and the compressed gas cylinder 4 can be gradually pushed toward the puncture needle 3.

[0057] When in use, the compressed gas cylinder 4 can be placed in the chamber 14 first, and then the adjusting cover 5 is covered, and the compressed gas cylinder 4 can be pushed toward the puncture needle 3 by rotating the adjusting cover 5. In this way, the top of the adjusting cover 5 can be closed. The adjusting cover 5 can also be installed on the inflation seat 1 first, and then the compressed gas cylinder 4 is installed into the chamber 14 through the adjusting cover 5. In this way, a through hole 51 needs to be provided on the top of the adjusting cover 5, and the compressed gas cylinder 4 is sent into the chamber 14 through the through hole 51. In order to still be able to push the compressed gas cylinder 4 toward the puncture needle 3 when the adjusting cover 5 is rotated. In some embodiments, the following structure is adopted, specifically, as Figure 5 and Figure 6 As shown, a push block 71 is provided on the inner side of the top of the regulating cover 5; the inflation assembly 400 also includes a return spring 72 and a rotating pressure plate 73 which is rotatably arranged in the chamber 14 and can move up and down relative to the inflation seat 1. One end of the return spring 72 is connected to the rotating pressure plate 73, and the other end is connected to the cavity wall of the chamber 14. When the regulating cover 5 is installed on the inflation seat 1, the through hole 51 is in an open state, see Figure 5 When the adjusting cover 5 is screwed in, the push block 71 rotates with the adjusting cover 5. When it rotates to abut against the rotating pressure plate 73 and the adjusting cover 5 continues to be screwed in, the push block 71 will push the rotating pressure plate 73 to rotate, so that the rotating pressure plate 73 covers the through hole 51, see Figure 6 When the regulating cover 5 is further screwed in, the top of the regulating cover 5 presses the rotating pressing plate 73 downward to drive the rotating pressing plate 73 to move downward. When the rotating pressing plate 73 moves downward, it pushes the compressed gas cylinder 4 against the puncture needle 3, so that the puncture needle 3 punctures the compressed gas cylinder 4. When the regulating cover 5 is screwed out of the inflation seat 1 to a certain position, the push block 71 releases the effect on the rotating pressing plate 73, and the rotating pressing plate 73 is reset under the action of the reset spring 72 and returns to the position. Figure 5 Status shown.

[0058] Continue to combine Figure 6 A downward side of the rotating pressing plate 73 is provided with a pushing rib so as to effectively push the compressed gas cylinder 4 downward through the pushing rib.

[0059] In some embodiments, Figures 1 to 3As shown, the inflatable seat 1 is provided with a pressure relief hole 81 connected to the chamber 14, and a sealing member 82, an elastic body 83 for pushing the sealing member 82 downward, and a push plate 84 provided above the elastic body 83 are provided above the pressure relief hole 81. When the adjustment cover 5 moves downward relative to the inflatable seat 1, it can push the push plate 84, and the push plate 84 acts on the elastic body 83, so that the elastic body 83 pushes the sealing member 82 downward to seal the pressure relief hole 81. The elastic body 83 can be a spring, and the use of a spring has a simple structure, good telescopic performance, and can ensure a sealing effect.

[0060] In order to ensure the pressure relief effect and improve the safety of use, the pressure relief holes 81 can be multiple and arranged around the compressed gas cylinder 4. The push plate 84 can be annular, and the annular push plate 84 acts on the multiple elastic bodies 83 on the multiple pressure relief holes 81 at the same time.

[0061] The embodiment of the present invention further provides a press rod assembly 500, such as Figures 7 to 10 As shown, the pressing rod assembly 500 includes a pressing rod 9 and an inflation assembly 400 of any of the above-mentioned embodiments, wherein a receiving chamber 91 is provided in the pressing rod 9, and the inflation assembly 400 is detachably provided in the receiving chamber 91. The pressing rod assembly 500 of this embodiment can be used in a juicer as a feeding push rod of the juicer, which is convenient for feeding. In addition, when the inflation assembly 400 is taken out from the pressing rod 9, it can be used to fill gas into the container to be inflated. For example, filling gas into the juice in the juice cup 300 can enhance the refreshing and spicy taste of the juice. Therefore, the pressing rod assembly 500 of this embodiment has multiple functions, and can be used as a feeding push rod, and can also conveniently store the inflation assembly 400.

[0062] In some embodiments, Figure 7 and Fig.10 As shown, the accommodating cavity 91 is formed by the first end of the pressing rod 9 being opened inwardly, and the first end of the pressing rod 9 is provided with an external thread 92; the inflatable seat 1 of the inflatable component 400 includes a seat body 11 and an extension portion 12 formed by extending outward from the middle of one side of the seat body 11, and an annular cavity is formed between the seat body 11 and the extension portion 12, and the cavity wall of the annular cavity is provided with an internal thread 13 (see Figure 3 ); the first end of the inflation tube 2 is connected to the extension part 12; when the first end of the pressing rod 9 is threadedly connected to the annular cavity, the inflation tube 2 and the extension part 12 extend into the accommodating cavity 91. The structural design is ingenious and reasonable. When the inflation component 400 is received in the pressing rod 9, the two form a whole, which is convenient for pushing the material.

[0063] like Figures 7 to 9 As shown, the top of the regulating cover 5 shown in this embodiment has a through hole 51, and the compressed gas cylinder 4 is loaded into the chamber 14 through the through hole 51. Fig.10As shown, the regulating cover 5 shown in this embodiment is sealed at the top and has no through hole 51. When in use, the compressed gas cylinder 4 needs to be first loaded into the chamber 14 of the inflatable seat 1, and then the regulating cover 5 is installed on the inflatable seat 1.

[0064] The embodiment of the present invention also provides a juice extractor, such as Fig.16 and Fig.17 As shown, the juicer includes a main body 100, a juice extraction component 200 disposed on the main body 100, a juice cup 300 for holding juice, and a juice cup 300 for receiving residues. The juicer also includes an aeration component 400 of any of the above embodiments, which can be disposed on the juice cup 300 and used to fill gas into the juice cup 300. Since the juicer has the aeration component 400, gas can be filled into the juice in the juice cup 300, so that the juice has a refreshing and spicy taste, which improves the drinking experience and meets the needs of the drinker. Moreover, the structure is simple and the aeration is convenient, which is conducive to promotion and use.

[0065] In some embodiments, Figures 12 to 15 As shown, the mouth of the juice cup 300 is provided with an external thread 92; the inflatable seat 1 of the inflatable assembly 400 includes a seat body 11 and an extension portion 12 formed by extending outward from the middle of one side of the seat body 11, and an annular cavity is formed between the seat body 11 and the extension portion 12, and an internal thread 13 is provided on the cavity wall of the annular cavity (see Figure 3 ); the first end of the gas-filling tube 2 is connected to the extension part 12; when the gas-filling seat 1 is threadedly connected to the mouth of the juice cup 300, the gas-filling tube 2 and the extension part 12 extend into the juice cup 300. The structural design is reasonable, the gas-filling assembly 400 is conveniently connected to the juice cup 300, and the gas-filling tube 2 can be extended to the position near the bottom of the juice cup 300, and the gas can be directly filled into the juice, so that the gas can be fully dissolved in the juice, thereby improving the effect and efficiency of gas-filling and improving the taste of the juice.

[0066] In some embodiments, the juicer further includes a press rod 9, a first end of the press rod 9 is provided with a receiving cavity 91, the gas component 400 can be received in the receiving cavity 91, the gas component 400 and the press rod 9 together form a press rod assembly 500, and the press rod assembly 500 is used as a feed push rod of the juicer. The adjustment cover 5 of the gas component 400 is exposed outside the receiving cavity 91, and can be used as a press cover of the press rod 9. The gas component 400 of the juicer of this embodiment can be received in the press rod 9, and together with the press rod 9 form the press rod assembly 500, which saves storage space.

[0067] In order to facilitate the disassembly of the inflation component 400 and the pressing rod 9, an external thread 92 is provided on the first end of the pressing rod 9; the first end of the pressing rod 9 can be threadedly connected to the annular cavity, and the inflation tube 2 and the extension part 12 are both extended into the accommodating cavity 91, which is conducive to saving space.

[0068] It should be noted that, in order to ensure the sealing during inflation, a sealing ring 64 is provided between the mouth of the juice cup 300 and the wall of the annular cavity. In addition, a sealing pad 32 is provided at the bottom of the chamber 14, and the needle of the puncture needle 3 extends into the chamber 14 through the sealing pad 32, so that when the compressed gas cylinder 4 is punctured by the puncture needle 3, the bottle mouth is pressed against the sealing pad 32 to prevent the gas in the compressed gas cylinder 4 from leaking out through the compressed gas cylinder 4 and the puncture needle 3. The inflation effect is improved.

[0069] The shape of the extension part 12 of the embodiment of the present invention can be similar to a truncated cone with a large upper end and a small lower end. When the first end of the inflation tube 2 is connected to the lower end of the extension part 12, the outer contours of the two are connected to form a whole. The shape of the inflation tube 2 can be conical. The outer peripheral surface of the upper end of the inflation seat 1 can be a cylindrical surface to cooperate with the adjustment cover 5 whose inner peripheral surface is also a cylindrical surface.

[0070] like Fig.11 and Fig.15 As shown, the adjustment cover 5 of the inflation assembly 400 has a through hole 51. When in use, the inflation tube 2 is first installed on the lower end of the inflation seat 1, and the adjustment cover 5 is installed on the upper end of the inflation seat 1. Then, the inflation seat 1 is connected to the cup mouth of the juice cup 300, and the inflation tube 2 and the extension part 12 are both extended into the juice cup 300. Finally, the compressed gas cylinder 4 is installed into the chamber 14 through the through hole 51 of the adjustment cover 5. By adjusting the adjustment cover 5, it moves downward relative to the inflation seat 1, and drives the rotating pressing plate 73 to press down the compressed gas cylinder 4, so that the puncture needle 3 punctures the compressed gas cylinder 4 and inflates the juice cup 300.

[0071] like Fig.13 and Fig.14 As shown, the adjustment cover 5 of the inflatable assembly 400 is not provided with a through hole 51. When in use, the inflatable seat 1 connected with the inflatable tube 2 can be first installed on the cup mouth of the juice cup 300, the inflatable tube 2 and the extension part 12 can be extended into the juice cup 300, and then the compressed gas cylinder 4 is installed in the chamber 14, and then the adjustment cover 5 is installed on the upper end of the inflatable seat 1. Alternatively, the compressed gas cylinder 4 can be first installed in the chamber 14, and then the adjustment cover 5 can be installed on the upper end of the inflatable seat 1, and then the inflatable tube 2 is connected to the lower end of the inflatable seat 1, and finally the connected inflatable assembly 400 is installed in the juice cup 300.

[0072] It should be noted that the present embodiment does not specifically limit the assembly sequence of the various components of the above-mentioned inflatable component 400, and the inflatable component 400 and the juice cup 300, as long as the ultimate purpose can be achieved. Similarly, the present embodiment does not specifically limit the assembly sequence of the various components of the inflatable component 400, and the inflatable component 400 and the press rod 9, as long as the ultimate purpose can be achieved.

[0073] The inflation process of the inflation component 400 of the present invention is described below with reference to the accompanying drawings.

[0074] First, the inflatable component 400 is placed into the juice cup 300. Before the inflatable component 400 is inflated, Figure 2 and Figure 3 As shown, the compressed gas cylinder 4 is located above the puncture needle 3, and the puncture needle 3 does not penetrate the compressed gas cylinder 4. The adjusting cover 5 does not press against the push plate 84, the elastomer 83 is in a released state, and the sealing member 82 does not press against the pressure relief hole 81. When the adjusting cover 5 is rotated downward, the top of the adjusting cover 5 first presses against the push plate 84, and the push plate 84 moves downward and compresses the elastomer 83. The elastomer 83 applies pressure to the sealing member 82, so that the sealing member 82 seals the pressure relief hole 81, and the gas in the juice cup 300 cannot leak out. The adjusting cover 5 continues to be rotated downward, and the adjusting cover pushes downward against the bottom of the compressed gas cylinder 4 to drive the compressed gas cylinder 4 to move downward. The mouth of the compressed gas cylinder 4 gradually approaches the puncture needle 3 and is punctured by the puncture needle 3, see Figure 1 and Figure 2 , and combined with Fig.12 , the gas in the compressed gas cylinder 4 enters the needle 3 and pushes the valve core 61 downward to open the gas one-way valve 6, and the gas enters the inflation tube 2 through the needle 3, and enters the juice through the inflation port 21 of the inflation tube 2 to complete the inflation of the juice. The juice has a refreshing and spicy taste, which improves the user experience. When the air pressure above the juice in the juice cup 300 is too high and greater than the preset pressure, the gas in the juice cup 300 pushes the seal 82 upward through the pressure relief hole 81, and the seal 82 pushes the elastic body 83 to be compressed, and the pressure relief hole 81 is opened to achieve pressure relief. After inflation, the juice cup 300 can be sealed with a cup cover 301 equipped therefor.

[0075] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations. The scope of the present invention should be determined with reference to the appended claims and the full range of equivalents to which these claims are entitled.
