Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a vacuum juice cup. Background Technology

[0002] Food spoilage is mainly caused by microbial activity. Most molds and yeasts depend on oxygen and suitable temperature for survival. Reducing oxygen content and lowering temperature can reduce microbial activity and prevent food oxidation.

[0003] In existing vacuum juice cups, the air pump is located on the lid and is connected to the liquid storage chamber of the cup body through a matching suction structure to create a vacuum and achieve the preservation effect. To prevent the liquid in the storage chamber from flowing back into the air pump through the suction structure and causing damage, a valve switch is often provided to control the opening and closing of the suction structure. However, in actual use, because there is still a distance between the internal sealing position of the valve switch and the air inlet of the suction structure, the liquid in the storage chamber can easily enter the air inlet, causing inconvenience for cleaning and easily leading to bacterial growth. Utility Model Content

[0004] Based on this, it is necessary to address the issue that the internal sealing position of the valve switch in the existing vacuum juice cup is still some distance from the air inlet of the suction structure, which makes it easy for liquid in the storage chamber to enter the air inlet, causing inconvenience for cleaning and easily leading to bacterial growth. Therefore, a vacuum juice cup should be provided.

[0005] A vacuum juice cup includes: a container body; a lid, the lid being detachably mounted on the container body, the lid and the container body forming a liquid storage cavity, the lid having an mounting cavity, and the side wall of the mounting cavity having an air extraction hole communicating with the liquid storage cavity; an air pump, the air pump being disposed in the mounting cavity, the air pump being used to expel gas from the liquid storage cavity; and a solenoid valve, the solenoid valve being disposed in the mounting cavity, the solenoid valve including a valve seat, a valve core, an electromagnetic component, and a seal, the valve seat having an air inlet and an air outlet, the air outlet communicating with the air pump, the air inlet being opposite to the air extraction hole, the air inlet communicating with the liquid storage cavity through the air extraction hole, the valve core being movably mounted on the valve seat, the seal being disposed at one end of the valve core, the valve core being configured to drive the seal to extend or retract relative to the air extraction hole under the magnetic force generated by the electromagnetic component, thereby opening or closing the air extraction hole.

[0006] This application provides a vacuum juice cup, whose solenoid valve includes a valve seat, a valve core, an electromagnetic component, and a seal. The valve seat connects the liquid storage chamber and the air pump. The air inlet of the valve seat is positioned opposite the air extraction hole of the cup lid. The valve core can extend and retract relative to the air extraction hole under the magnetic force generated by the electromagnetic component. This allows the seal on the valve core to connect or separate from the air extraction hole, opening and closing the air extraction hole. Compared with the valve switch in the prior art vacuum juice cup, the seal can directly seal the air extraction hole under the drive of the valve core, thereby effectively overcoming the water retention defect at the air extraction hole and ensuring safer and more hygienic use of the vacuum juice cup.

[0007] In one embodiment, the bottom of the mounting cavity is provided with the vent hole, and the valve core is located above the vent hole. The valve core is configured to extend and retract relative to the vent hole in the height direction under the magnetic force generated by the electromagnetic component and has at least a first position and a second position. When the valve core is in the first position, the end of the seal away from the valve core seals against the end face of the vent hole to close the vent hole. When the valve core is in the second position, the seal separates from the end face of the vent hole, and the vent hole opens and connects the air inlet and the liquid storage cavity. By adopting the above structure, when the air pump is working and drawing air from the liquid storage chamber, the solenoid valve drives the valve core to rise from the first position to the second position. Thus, the air inlet of the pump body can be connected to the liquid storage chamber in sequence through the air outlet, air inlet, and air extraction hole, so that the gas can be drawn out smoothly. When the air extraction is completed, the driving force on the valve core disappears, so the valve core can fall back to the first position under the action of gravity and abut against the end face of the air extraction hole, thereby sealing the air extraction hole and preventing the liquid in the liquid storage chamber from flowing back into the installation cavity.

[0008] In one embodiment, the bottom wall of the mounting cavity is recessed to form a first positioning groove, and the bottom wall of the first positioning groove is provided with the air extraction hole. When the valve core is in the first position, at least a portion of the sealing element is located in the first positioning groove. The first positioning groove facilitates the positioning and installation of the sealing element, allowing the sealing ring to align with the air extraction hole and extend under the action of the valve core. It also increases the connection area between the sealing element and the cup lid, thus better ensuring the sealing effect.

[0009] In one embodiment, the valve seat includes a housing body and a sealing cap. The sealing cap is disposed on the housing body, and one end of the sealing cap away from the housing body abuts against the side wall of the cup lid where the vent hole is located. The sealing cap has the air inlet, and the housing body has the air outlet. The sealing cap and the housing body enclose each other to form an airflow channel, which connects the air inlet and the air outlet. By adopting the above structure, the housing body abuts against the side wall of the cup lid where the vent hole is located through the sealing cap, thereby ensuring the airtightness of the connection between the sealing cap and the housing body and the cup lid, ensuring that the air in the liquid storage chamber can be efficiently extracted by the air pump, and that other parts in the installation chamber are not affected.

[0010] In one embodiment, the housing body includes a mounting base and a flow guide. The mounting base is sealed to the sealing cap and forms a first air passage chamber. The flow guide is located on the side of the mounting base away from the sealing cap and has a communicating second air passage chamber and an air outlet. The first air passage chamber and the second air passage chamber communicate to form the airflow channel. The mounting base has a mounting hole opposite to the air inlet, and the mounting hole communicates with the air inlet. The valve core and / or the electromagnetic assembly is disposed in the mounting hole. By forming a housing body composed of a mounting base and a flow guide, designers can more easily arrange the air pump and solenoid valve according to the overall shape requirements of the juice cup, making the connection between the solenoid valve and the air pump more convenient.

[0011] In one embodiment, a first mounting portion is formed on the side of the mounting base facing the first air passage cavity. The first mounting portion has the mounting hole, and the valve core is movably disposed in the mounting hole. The outer peripheral wall of the seal protrudes to form an annular first sealing skirt on the side away from the air extraction hole. The first sealing skirt is used to seal against the bottom wall of the first mounting portion. Specifically, by adopting the above structure, when the air pump operates to extract air from the liquid storage cavity, the solenoid valve operates to drive the valve core to rise from the first position to the second position, so that the first sealing skirt seals against the bottom wall of the first mounting portion, thereby blocking the mounting hole from the air inlet and / or the first air passage cavity, ensuring that the air in the liquid storage cavity can be efficiently extracted by the air pump, and that other parts in the mounting cavity are not affected.

[0012] In one embodiment, the mounting base has a second mounting portion facing outwards, and the second mounting portion has the mounting hole, in which the electromagnetic component is located. By forming the outwardly protruding second mounting portion, it is easier for installers to install the electromagnetic component, thus improving installation efficiency.

[0013] In one embodiment, the outer wall of the housing body has a protruding connecting lug with a first connecting hole, and the inner wall of the cup lid has a protruding connecting post with a second connecting hole. The first connecting hole and the second connecting hole are connected to the connecting lug and the connecting post by fasteners. By adopting the above structure, the connecting lug and the connecting post are secured with fasteners, allowing both sides of the sealing cap to be tightly connected to the housing body and the cup lid respectively. This ensures the airtightness of the connections between the sealing cap and the housing body and the cup lid, and ensures that air in the liquid storage chamber can be efficiently extracted by the air pump.

[0014] In one embodiment, the sealing cover has a mounting groove, the bottom wall of which has an air inlet, and the end of the housing body away from the air outlet is fitted into the mounting groove. The mounting groove provides a positioning function, making it easier to align and connect the housing body and the sealing cover, and increasing the connection area between them to better ensure a sealing effect.

[0015] In one embodiment, the inner wall of the cup lid protrudes to form a limiting ring, and the sealing cap is fitted into the limiting ring. The limiting ring provides a positioning function, making it easier to position and install the solenoid valve on the cup lid, and also increasing the connection area between the cup lid and the sealing cap, thus better ensuring a sealing effect.

[0016] In one embodiment, the solenoid valve further includes a spring, with its two ends abutting against the valve core and valve seat, respectively. Specifically, when the valve core moves from the first position to the second position, the spring deforms and accumulates elastic force to drive the valve core back to the first position from the second position. By using the spring, when the driving force on the valve core disappears, the spring will quickly and elastically return to its original position, driving the valve core and seal back to their original positions for the next use, simplifying user operation. Furthermore, the spring provides resistance, effectively preventing liquid in the reservoir from breaching the seal and entering the reservoir.

[0017] In one embodiment, the seal includes a sealing body and a second sealing skirt. The sealing body is sleeved on one end of the valve core and is disposed opposite to the vent hole. The outer peripheral wall of the sealing body has an annular second sealing skirt on the side closer to the vent hole. The second sealing skirt is configured to seal against the end face of the vent hole together with the sealing body. By adopting the above structure, the second sealing skirt and the sealing body cooperate to seal against the end face of the vent hole, thereby effectively ensuring that the liquid in the reservoir cavity does not leak from the vent hole into the solenoid valve assembly.

[0018] In one embodiment, a pressure relief assembly is also included, which is connected to the liquid storage chamber and is used to release pressure inside the liquid storage chamber to maintain pressure stability. With the pressure relief assembly, the user can release pressure in the liquid storage chamber before opening the lid to avoid difficulty in opening the lid after vacuuming, and also enhances safety.

[0019] In one embodiment, a food processing device is also included, which is disposed on the cup lid and partially extends into the liquid storage cavity. The food processing device allows users to conveniently process fruits and vegetables to make fresh juice at any time, greatly improving the user experience.

[0020] In one embodiment, a lighting device is also included, which is disposed within the lid and forms a ring-shaped light-emitting portion exposed to the outside. The lighting device enhances the aesthetics of the vacuum juicer and makes it easier for users to use the vacuum juicer in the dark. Attached Figure Description

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention 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 invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0037] The vacuum juice cup of the present invention is described below with reference to the accompanying drawings.

[0038] like Figures 1 to 6 As shown, this embodiment discloses a vacuum juice cup, including: a container body 1; a cup lid 2, which is detachably mounted on the container body 1, forming a liquid storage cavity 101 with the container body 1, and the cup lid 2 has an installation cavity 201, the side wall of which has an air extraction hole 202 communicating with the liquid storage cavity 101; an air pump 3, which is disposed in the installation cavity 201 and is used to discharge gas from the liquid storage cavity 101; and a solenoid valve 4, which is disposed in the installation cavity 201 and includes a valve seat 41 and a valve core 42. The electromagnetic component 43 and the sealing element 44 are provided. The valve seat 41 is provided with an air inlet 401 and an air outlet 403. The air outlet 403 is connected to the air pump 3. The air inlet 401 is arranged opposite to the air extraction hole 202. The air inlet 401 is connected to the liquid storage chamber 101 through the air extraction hole 202. The valve core 42 is movably arranged on the valve seat 41. The sealing element 44 is arranged at one end of the valve core 42. The valve core 42 is configured to drive the sealing element 44 to move relative to the air extraction hole 202 under the magnetic force generated by the electromagnetic component 43, so as to open or close the air extraction hole 202.

[0039] This application provides a vacuum juice cup, whose solenoid valve 4 includes a valve seat 41, a valve core 42, an electromagnetic component 43, and a sealing element 44. The valve seat 41 connects the liquid storage chamber 101 and the air pump 3. The air inlet 401 of the valve seat 41 is positioned opposite to the air extraction hole 202 of the cup lid 2. The valve core 42 can extend and retract relative to the air extraction hole 202 under the magnetic force generated by the electromagnetic component 43. This allows the sealing element 44 on the valve core 42 to connect or separate from the air extraction hole 202, opening and closing the air extraction hole 202. Compared with the valve switch of the vacuum juice cup in the prior art, the sealing element 44 can directly seal the air extraction hole 202 under the drive of the valve core 42, thereby effectively overcoming the water retention defect at the air extraction hole 202 and ensuring that the vacuum juice cup is safer and more hygienic to use.

[0040] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom of the mounting cavity 201 is provided with an air extraction hole 202, the valve core 42 is located above the air extraction hole 202, the valve core 42 is configured to be able to extend and retract relative to the air extraction hole 202 in the height direction under the magnetic force generated by the electromagnetic component 43 and has at least a first position and a second position. When the valve core 42 is in the first position, the end of the sealing member 44 away from the valve core 42 seals and abuts against the end face of the air extraction hole 202 so that the air extraction hole 202 is closed. When the valve core 42 is in the second position, the sealing member 44 separates from the end face of the air extraction hole 202, the air extraction hole 202 is opened and connects the air inlet 401 and the liquid storage cavity 101. By adopting the above structure, when the air pump 3 is working to draw air from the liquid storage chamber 101, the solenoid valve 4 drives the valve core 42 to rise from the first position to the second position. Thus, the air inlet of the pump body can be connected to the liquid storage chamber 101 in sequence through the air outlet 403, the air inlet 401, and the air extraction hole 202, so that the gas can be drawn out smoothly. When the air extraction is completed, the driving force on the valve core 42 disappears, so the valve core 42 can fall back to the first position under the action of gravity and abut against the end face of the air extraction hole 202. Thus, the air extraction hole 202 can be blocked to prevent the liquid in the liquid storage chamber 101 from flowing back into the installation chamber 201.

[0041] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom wall of the mounting cavity 201 is recessed to form a first positioning groove 203, and the bottom wall of the first positioning groove 203 is provided with an air extraction hole 202. When the valve core 42 is in the first position, at least a portion of the sealing member 44 is located in the first positioning groove 203. The first positioning groove 203 facilitates the positioning and installation of the sealing member 44, so that the sealing ring can be aligned with the air extraction hole 202 and expand and contract under the action of the valve core 42, and the connection area between the sealing member 44 and the cup lid 2 can be increased, thereby better ensuring the sealing effect.

[0042] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the valve seat 41 includes a housing body 411 and a sealing cover 412. The sealing cover 412 is disposed on the housing body 411. The end of the sealing cover 412 away from the housing body 411 abuts against the side wall of the cup lid 2 where an air extraction hole 202 is provided. The sealing cover 412 is provided with an air inlet 401, and the housing body 411 is provided with an air outlet 403. The sealing cover 412 and the housing body 411 enclose each other to form an airflow channel 402, which connects the air inlet 401 and the air outlet 403. By adopting the above structure, the housing body 411 abuts against the side wall of the cup lid 2 where an air extraction hole 202 is provided through the sealing cover 412. This ensures the airtightness of the connection between the sealing cover 412 and the housing body 411 and the cup lid 2, ensuring that the air in the liquid storage chamber 101 can be efficiently extracted by the air pump 3, and that other parts in the mounting cavity 201 are not affected.

[0043] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing body 411 includes a mounting base 4111 and a guide portion 4112. The mounting base 4111 is sealed and connected to the sealing cover 412 to form a first air passage 4021. The guide portion 4112 is disposed on the side of the mounting base 4111 away from the sealing cover 412. The guide portion 4112 is provided with a second air passage 4022 and an air outlet 403 that are connected. The first air passage 4021 and the second air passage 4022 are connected to form an airflow channel 402. The mounting base 4111 is provided with a mounting hole 404 opposite to the air inlet 401. The mounting hole 404 is connected to the air inlet 401. The valve core 42 and / or electromagnetic component 43 are disposed in the mounting hole 404. By forming a housing body 411 consisting of a mounting base 4111 and a flow guide 4112, designers can more easily arrange the air pump 3 and solenoid valve 4 in accordance with the overall shape requirements of the juice cup, making the connection between the solenoid valve 4 and the air pump 3 more convenient.

[0044] like Figure 4 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first mounting portion 41111 is formed on the side of the mounting base 4111 facing the first air passage 4021, the first mounting portion 41111 is provided with a mounting hole 404, the valve core 42 is movably disposed in the mounting hole 404, and the outer peripheral wall of the sealing member 44 protrudes to form an annular first sealing skirt 441 on the side away from the air extraction hole 202, the first sealing skirt 441 is used to seal against the bottom wall of the first mounting portion 41111. Specifically, by adopting the above structure, when the air pump 3 operates to draw air from the liquid storage chamber 101, the solenoid valve 4 operates to drive the valve core 42 to rise from the first position to the second position, so that the first sealing skirt 441 seals against the bottom wall of the first mounting part 41111, thereby blocking the mounting hole 404 from the air inlet 401 and / or the first air passage chamber 4021, ensuring that the air in the liquid storage chamber 101 can be efficiently drawn out by the air pump 3, and that other parts in the mounting cavity 201 are not affected.

[0045] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting base 4111 has a second mounting portion 41112 formed outward, the second mounting portion 41112 is provided with a mounting hole 404, and the electromagnetic component 43 is located in the mounting hole 404. By forming the outwardly protruding second mounting portion 41112, it is more convenient for installers to install the electromagnetic component 43, thereby improving installation efficiency.

[0046] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a connecting ear 4113 is formed by a protrusion on the outer wall of the housing body 411, and the connecting ear 4113 is provided with a first connecting hole 405; a connecting post 21 is formed by a protrusion on the inner wall of the cup lid 2, and the connecting post 21 is provided with a second connecting hole; the first connecting hole 405 and the second connecting hole are connected to the connecting ear 4113 and the connecting post 21 by fasteners. By adopting the above structure, after the connecting ear 4113 and the connecting post 21 are fastened together by fasteners, both sides of the sealing cover 412 can be tightly connected to the housing body 411 and the cup lid 2 respectively, thereby ensuring the airtightness of the connection between the sealing cover 412 and the housing body 411 and the cup lid 2 respectively, and ensuring that the air in the liquid storage chamber 101 can be efficiently extracted by the air pump 3.

[0047] like Figure 4 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the sealing cover 412 is provided with a mounting groove, the bottom wall of the mounting groove is provided with an air inlet 401, and the end of the housing body 411 away from the air outlet 403 is fitted and installed in the mounting groove. The mounting groove provides a positioning function, making it easier to align and connect the housing body 411 and the sealing cover 412, and increasing the connection area between the housing body 411 and the sealing cover 412, thus better ensuring the sealing effect.

[0048] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner wall of the cup lid 2 protrudes to form a limiting ring 22, and the sealing cap 412 is adapted to be inserted into the limiting ring 22. The setting of the limiting ring 22 can form a positioning function, so as to facilitate the positioning and installation of the solenoid valve 4 on the cup lid 2, and can increase the connection area between the cup lid 2 and the sealing cap 412, thereby better ensuring the sealing effect.

[0049] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the solenoid valve 4 also includes a spring 45, the two ends of which abut against the valve core 42 and the valve seat 41, respectively. Specifically, when the valve core 42 moves from the first position to the second position, the spring 45 deforms and accumulates elastic force to drive the valve core 42 to return from the second position to the first position. With the spring 45, when the driving force on the valve core 42 disappears, the spring 45 will quickly and elastically recover and drive the valve core 42 and the seal 44 to return to their original positions for the next round of use, simplifying the user's operation; in addition, the spring 45 can form resistance, thereby effectively preventing liquid in the liquid storage chamber 101 from breaking through the seal 44 and entering the liquid storage chamber 101.

[0050] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the sealing member 44 includes a sealing body 442 and a second sealing skirt 443. The sealing body 442 is sleeved on one end of the valve core 42, and the sealing body 442 is disposed opposite to the vent hole 202. The outer peripheral wall of the sealing body 442 is provided with an annular second sealing skirt 443 on the side closer to the vent hole 202. The second sealing skirt 443 is configured to seal against the end face of the vent hole 202 together with the sealing body 442. By adopting the above structure, the second sealing skirt 443 and the sealing body 442 cooperate to seal against the end face of the vent hole 202, thereby effectively ensuring that the liquid in the liquid storage chamber 101 will not leak from the vent hole 202 to the solenoid valve 4 assembly.

[0051] like Figure 1As shown, in addition to the features of the above embodiments, this embodiment further includes a pressure relief component 5, which is connected to the liquid storage chamber 101. The pressure relief component 5 is used to relieve pressure inside the liquid storage chamber 101 to maintain pressure stability. With the pressure relief component 5, the user can relieve pressure in the liquid storage chamber 101 before opening the lid to avoid the lid being difficult to open after vacuuming, and it also makes use safer.

[0052] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a food processing device 6, which is disposed on the cup lid 2 and partially extends into the liquid storage chamber 101. The food processing device 6 allows users to conveniently process fruits and vegetables to make fresh fruit and vegetable juices at any time, greatly improving the user experience.

[0053] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a lighting device 7, which is disposed in the cup lid 2 and forms a ring-shaped light-emitting part 71 exposed to the outside. The lighting device 7 enhances the aesthetics of the vacuum juice cup and makes it more convenient for users to use the vacuum juice cup in the dark.

[0054] 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.

[0055] 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.
