Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a vacuum upper cover and a juicer using the same. Background Art

[0002] A juicer, also known as a wall-breaking machine, is an industrial product that processes vegetables or fruits by physical means such as squeezing, centrifugation and extraction to obtain fruit and vegetable juice, which is convenient for people to supplement multiple vitamins. During the juicing process, the highly active phenolase in fruits and vegetables will be released when their cells are broken and fully contacted with oxygen in the air, thereby oxidizing the polyphenols and vitamins in the fruits, causing the fruit and vegetable juice to lose some nutrients and browning, which affects the taste and appearance of the fruit and vegetable juice.

[0003] Since fruit and vegetable juices are easily oxidized and deteriorate in the air, people have invented juicers that can evacuate the juicer cup. A vacuum pump is installed in the sealing cover of the blender cup or the base of the juicer cup to evacuate the cup. When the vacuum pump is started, a certain degree of vacuum is formed in the cup containing the fruit and vegetable juice, thereby extending the preservation time and making it easier for people to drink fresh fruit and vegetable juice.

[0004] However, the existing juicers have the following problems. First, the exhaust system structure in the existing juicer cover is unreasonable. After the vacuum pump stops working, air is easy to flow back in the exhaust system, thereby reducing the vacuum effect inside the juicer. Second, the vacuum treatment of the juicer is mainly completed by the vacuum pump, and the vacuum pump needs to be started by a motor. Therefore, during the operation of the vacuum device, the temperature of the motor that controls the start of the vacuum pump will increase. The juicer cover with a vacuum device will more or less dissipate heat to the outside. If the user continues to use the juicer in a short period of time, resulting in the motor temperature not being able to drop in time or the heat of the vacuum device not being able to be dissipated in time, there will be great safety hazards.

[0049] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0050] In the description of the present invention, it is necessary to understand that the terms "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] A vacuum upper cover, comprising a cover body A, a vacuum device B, an exhaust structure C and an air intake structure D;

[0052] The air intake structure D is provided with a one-way exhaust mechanism D3, and the one-way exhaust mechanism D3 is used to allow gas to enter the air intake structure D in one direction;

[0053] The vacuum device B is located inside the cover body A, and the air intake structure D is located at the bottom of the cover body A. The vacuum device B is used to extract gas into the interior of the cover body A through the air intake structure D;

[0054] A guide groove A11 is provided at the bottom of the cover body A, and the outlet end of the vacuum pumping device B leads to the guide groove A11;

[0055] The top of the cover body A is provided with the exhaust structure C, and the exhaust structure C is used to exhaust the gas inside the cover body A to the outside of the cover body A.

[0056] In the prior art, the sealing cover of the mixing cup with a vacuum device is provided with an exhaust structure, which is generally an exhaust hole provided on the surface of the sealing cover of the mixing cup, and the exhaust hole is connected to the inner cavity of the sealing cover of the mixing cup. When the juicer is vacuuming, the gas in the mixing cup is drawn into the inner cavity of the sealing cover of the mixing cup by the action of the vacuum pump, and then discharged into the atmosphere through the exhaust hole connected to the inner cavity.

[0057] Normally, the gas in the inner cavity is generally discharged directly into the atmosphere through the exhaust hole. However, in the present technical solution, the gas in the vacuum upper cover is refluxed and the guide groove A11 structure is provided to allow the gas to fill the entire cavity, so that the gas takes away the heat emitted by the vacuum device B in the vacuum upper cover during the discharge process, thereby avoiding safety hazards caused by the motor temperature of the vacuum upper cover failing to drop in time or the heat of the vacuum device B failing to dissipate in time.

[0058] Specifically, the present technical solution provides a vacuum cover, such as Figure 1-15 As shown, it includes a cover body A, a vacuum device B, an exhaust structure C and an air intake structure D. The vacuum device B first draws the gas into the interior of the cover body A, and then passes it to the guide groove A11 located at the bottom of the cover body A through reflux treatment. Because the air pressure outside the vacuum upper cover is small and the air pressure inside the vacuum upper cover is large during vacuuming, the gas inside the cover body A will flow to the exhaust structure C located at the top of the cover body A under the combined action of the air pressure and the guide groove A11, thereby forming an ascending airflow from the bottom of the cover body A to the top of the cover body A inside the cover body A, which is beneficial to the discharge of the gas from bottom to top after reflux, thereby achieving timely heat dissipation during the exhaust process.

[0059] It should be noted that the present technical solution includes but is not limited to the following structures that can realize reflux treatment: in one embodiment of the present technical solution, the vacuum device B can be connected to the air outlet pipe, the air inlet end of the air outlet pipe is connected to the air outlet nozzle of the vacuum device B, and the air outlet end of the air outlet pipe leads to the guide groove A11, thereby performing reflux treatment on the gas of the air outlet nozzle of the vacuum device B; in another embodiment of the present technical solution, the inner side wall of the vacuum device B may be provided with a guide channel, the inlet of the guide channel is connected to the air outlet nozzle of the vacuum device B, and the outlet of the guide channel leads to the guide groove A11, thereby performing reflux treatment on the gas of the air outlet nozzle of the vacuum device B.

[0060] Furthermore, due to the unreasonable air intake structure in the vacuum cover of the existing juicer, after the vacuum pump stops working, the air is easy to flow back in the exhaust system. In order to avoid the backflow of gas to the bottom of the vacuum cover and prevent the vacuum effect of the vacuum cover from being reduced, the technical solution also provides a one-way exhaust mechanism D3 in the air intake structure D, and the one-way exhaust mechanism D3 is used to allow the gas to enter the air intake structure D in one direction.

[0061] Preferably, the vacuum cover also includes an anti-slip member E, such as Figure 14-15 As shown, the bottom of the cover body A is provided with a mounting groove E11, and the bottom of the mounting groove E11 is provided with a limited position accommodating portion, and the anti-slip member E is detachably installed in the mounting groove E11, and the anti-slip member E is provided with a fixing portion toward the mounting groove E11, and the fixing portion is detachably installed in the limited position accommodating portion. The vacuum upper cover of the vacuum juicer and the juicer body are generally a rotary detachable mounting structure. In order to ensure the sealing and anti-slip properties between the vacuum upper cover and the juicer body, increase the friction of rotation, and make the vacuum upper cover easy to open, an anti-slip member E is provided at the junction of the vacuum upper cover and the juicer body. Generally, the anti-slip member E is provided with a thread groove, which is used to cooperate with the thread ring at the junction to increase the friction. However, as the use time increases, debris or impurities will accumulate in the thread ring. Since the thread ring is a structure that is concave inward, it is very difficult to clean. However, the present technical solution abandons the design of the threaded ring and adopts a method of setting a limited accommodation portion on the cover body A and a fixing portion on the anti-slip part E. By utilizing the cooperation of the limited accommodation portion and the fixing portion, the anti-slip part E can be fixed on the cover body A without moving, thereby ensuring the sealing performance and making disassembly and installation more convenient.

[0062] Preferably, the anti-slip member E includes an annular gasket E21 and the fixing portion, wherein the fixing portion is arranged on the upper surface of the annular gasket E21; the fixing portion is buckled with the position limiting accommodating portion, so that the annular gasket E21 is fixed in the mounting groove E11. The annular gasket E21 of the anti-slip member E is laid on the bottom surface of the mounting groove E11, and when the vacuum upper cover is combined with the juicer body, the top of the cup mouth of the juicer body is against the annular gasket E21, which ensures the sealing performance and makes the annular gasket E21 located below the threaded ring, and there is no need to provide a threaded groove on the annular gasket E21.

[0063] Preferably, the fixing portion includes a C-shaped rib E22, which is arranged around the inner ring edge of the annular gasket E21, and the C-shaped rib E22 is located on the upper surface of the annular gasket E21, forming a step with the upper surface of the annular gasket E21. The position-limiting accommodation portion is an inwardly recessed C-shaped anti-skid groove E12, the C-shaped anti-skid groove E12 matches the C-shaped rib E22, the C-shaped rib E22 is arranged in the C-shaped anti-skid groove E12, and both ends of the C-shaped rib E22 are rounded transition structures.

[0064] The chamfered transition structure is adopted so that the C-shaped rib E22 can be aligned and installed in the C-shaped anti-skid groove E12 more quickly. In this embodiment, the fixing part of the anti-skid member E is set as the C-shaped rib E22, the C-shaped rib E22 is a ring structure with a notch, and the C-shaped anti-skid groove E12 is a groove that matches the C-shaped rib E22. When installing, the C-shaped rib E22 is just placed in the C-shaped anti-skid groove E12. When the vacuum upper cover is rotated, the two ends of the C-shaped rib E22 are supported by the two ends of the C-shaped anti-skid groove E12 and cannot rotate, which can prevent the anti-skid member E2 from rotating with the vacuum upper cover, resulting in a reduction in friction.

[0065] Preferably, the surface of the C-shaped rib E22 is upwardly protruding to form a plurality of anti-skid ribs E23, and the anti-skid ribs E23 are distributed at intervals on the surface of the C-shaped rib E22, and the anti-skid ribs E23 are arranged upward. The bottom of the C-shaped anti-skid groove E12 is recessed to form an anti-skid rib groove E13, and the anti-skid rib groove E13 corresponds to the anti-skid rib E23 one by one. In order to further prevent the anti-skid part E from rotating in the installation groove E11, the anti-skid rib groove E13 is arranged in the C-shaped anti-skid groove E12, and the anti-skid rib E23 that can be placed in the anti-skid rib groove E13 is arranged on the C-shaped rib E22, and the anti-skid rib E23 further prevents the anti-skid part E from rotating when the vacuum upper cover rotates.

[0066] Preferably, the annular gasket E21 completely covers the installation groove E11, and the annular gasket E21 can completely cover the bottom of the installation groove E11 by cooperating with the C-shaped rib E22 to ensure its sealing.

[0067] Further, the inner wall of the cover body A is provided with a guide rib A13, and the bottom of the guide rib A13 abuts against the top of the notch of the guide groove A11;

[0068] The inner groove wall of the guide groove A11 is a first groove wall A111 . The first groove wall A111 is inclined, and the vertical cross section of the guide groove A11 is in an inverted right-angle trapezoidal shape.

[0069] like Figure 4 As shown, the inner wall of the cover body A is provided with a guide rib A13, which guides the gas in the guide groove A11, thereby facilitating the gas in the guide groove A11 to flow toward the exhaust structure C along the direction of the guide rib A13.

[0070] Since the gas in the guide groove A11 flows back from the outlet of the vacuum device B, in actual use, the manufacturer can open one or more gas outlets in the guide groove A11 according to the actual needs, so that the gas fills the guide groove A11. However, for the purpose of simplifying the process and reducing the volume, usually only one gas outlet is opened in the guide groove A11. Therefore, in order to simplify the process and reduce the volume, while improving the heat dissipation effect, in this technical solution, the bottom of the guide rib A13 is pressed against the top of the notch of the guide groove A11, so that the gas can flow to various parts of the guide groove A11 through the gap between the guide rib A13 and the groove wall of the guide groove A11, which is conducive to the gas filling the entire cavity and playing a sufficient heat dissipation role.

[0071] Preferably, a plurality of guide ribs A13 are provided, and the plurality of guide ribs A13 are distributed along the edge of the guide groove A11 or arranged in a ring shape, which is beneficial to reducing the dispersion of the airflow during the discharge process.

[0072] The inner groove wall of the guide groove A11 is the first groove wall A111, and the first groove wall A111 is inclined so that the vertical cross-section of the guide groove A11 is set in an inverted right-angle trapezoid. Due to the effect of air pressure, the gas inside the cover body A will form an ascending airflow from the bottom of the cover body A to the top of the cover body A. Therefore, in the process of the gas in the guide groove A11 flowing to the top of the cover body A, it can flow along the inclined first groove wall A111 to the middle of the cover body A, and then be discharged from the exhaust structure C to the outside of the vacuum upper cover. When the gas flows to the middle of the cover body A, it is beneficial to increase the contact area between the exhaust gas and the vacuum device B, so that the gas can take away the heat generated by the vacuum device B during the exhaust process, which helps to improve the heat dissipation effect of the vacuum upper cover.

[0073] Further, the inner wall of the cover body A is further provided with a guide bar A14, the guide bar A14 is located between the guide ribs A13, and the guide bar A14 and the guide ribs A13 are parallel to each other;

[0074] The vertical cross section of the guide bar A14 is arranged in the shape of an inverted right triangle, the vertical side of the right triangle is connected to the inner wall of the cover body A, and the hypotenuse of the right triangle is protruding from the inner wall of the cover body A.

[0075] The inner side wall of the cover body 1 is further provided with a guide strip A14, and the guide strip A14 and the guide rib A13 are parallel to each other, which is beneficial to further reduce the dispersion of the airflow during the discharge process and ensure the realization of the guide effect.

[0076] In one embodiment of the present technical solution, the vertical cross-section of the guide bar A14 is set in an inverted right triangle, and the guide bar A14 is protruding from the inner wall of the cover body A. When the rising airflow starting from the guide groove A11 encounters the guide bar A14, it is easy to gather to the middle part of the cover body A under the action of the hypotenuse. On the one hand, it is beneficial to the centralized discharge of gas to avoid the exhaust gas staying on the edge of the cover body A and cannot be discharged in time. On the other hand, when the gas flows to the middle part of the cover body A, it is also beneficial to increase the contact area between the exhaust gas and the vacuum device B, which is beneficial for the gas to take away the heat generated by the vacuum device B during the discharge process, which helps to improve the heat dissipation effect of the vacuum upper cover.

[0077] Preferably, the opening edge of the cover body A is provided with an inclined surface extending outward, and the inclined surface is an inclined surface arranged downwardly toward the periphery of the cover body A. Furthermore, the technical solution also extends the opening edge of the cover body A outwardly with an inclined surface, and the inclined surface is arranged downwardly toward the periphery of the cover body 1. When water stays on the top of the vacuum upper cover, it can flow toward the vacuum upper cover along the opening edge of the cover body A arranged downwardly, which can reduce the probability of water entering the interior of the vacuum upper cover and improve the waterproof performance of the vacuum upper cover structure.

[0078] Further, the air intake structure D is provided with an air intake mounting seat D11, the one-way exhaust mechanism D3 is provided on the top of the air intake mounting seat D11, the air intake mounting seat D11 is provided with an air vent D12, and the one-way exhaust mechanism D3 and the air intake structure D are connected to each other through the air vent D12;

[0079] The one-way exhaust mechanism D3 includes a sheet-shaped elastic valve body D32, the edge of the elastic valve body D32 has a supporting portion D321, and the supporting portion D321 abuts against the inner wall of the intake mounting seat D11;

[0080] The elastic valve body D32 is provided with an exhaust hole D322, the elastic valve body D32 covers the vent hole D12, and the exhaust hole D322 and the vent hole D12 are staggered.

[0081] The elastic valve body D32 can be deformed and bulged, allowing gas to enter the air intake structure D through the vent hole D12 and the exhaust hole D322 in sequence.

[0082] like Figure 8-13As shown, the exhaust hole D322 and the vent hole D12 are staggered with each other, which means that the position of the exhaust hole D322 and the position of the vent hole D12 are staggered with each other to avoid direct communication between the vent hole D12 and the exhaust hole D322.

[0083] The elastic valve body D32 may be made of silicone or plastic, so that the elastic valve body D32 can be deformed and bulge.

[0084] The working process of the elastic valve body D32 in the present technical solution is as follows: when the vacuum pumping device B is working, the vacuum pumping device B generates suction force on the elastic valve body D32, so that the elastic valve body D32 is deformed and bulged. Specifically, when the elastic valve body D32 is deformed and bulged, the vent D12 is connected with the exhaust hole D322, so that the gas enters the intake structure D through the vent D12 and the exhaust hole D322 in sequence.

[0085] When the vacuum device B stops working, the elastic valve body D32 returns to its original state, and the elastic valve D32 covers the vent hole D12, so that the vent hole D12 and the exhaust hole D322 are in a non-connected state, preventing the gas from flowing back out of the air intake structure D, thereby improving the vacuum degree of the juicer and reducing the oxidation degree of the nutrients in the fruit and vegetable juice.

[0086] Preferably, the edge of the elastic valve body D32 is provided with a reverse folding edge D323, and the reverse folding edge D323 and the outer wall of the abutting portion D321 form a groove D324, and the top edge of the air intake mounting seat D11 is located in the groove D324 and has an interference fit with the groove D324. The top edge of the air intake mounting seat D11 is located in the groove D324 and has an interference fit with the groove D324, so that the elastic valve body D32 is tightly installed in the air intake mounting seat D11, and the elastic valve body D32 is prevented from falling off from the air intake mounting seat D11, resulting in failure to cover the vent D12.

[0087] Further, the one-way exhaust mechanism D3 further includes a pressure code D33, and the pressure code D33 is used to press the abutment portion D321 against the air intake mounting seat D11;

[0088] The pressure code D33 is provided with a cavity D331 and an air outlet D332. The air outlet D332 is connected to the vacuum device B. The top of the cavity D331 is connected to the air outlet D332. The bottom of the cavity D331 is connected to the exhaust hole D322. The cavity D331 is used to provide space for the deformation of the elastic valve body D32.

[0089] In the present technical solution, the air suction pipe of the vacuum device B is connected to the air outlet D332. When the vacuum device B is working, the cavity D331 is in a negative pressure state, and the elastic valve body D32 is deformed and bulged due to the pressure difference, so that the gas can enter the air intake structure D through the air vent D12 and the exhaust hole D322 in turn.

[0090] Preferably, the pressing code D33 has a pressing convex edge D333, and the outer wall surface of the pressing convex edge D333 cooperates with the inner wall surface of the air intake mounting seat D11 to press the elastic valve body D32. The outer wall surface of the pressing convex edge D333 cooperates with the inner wall surface of the air intake mounting seat D11, thereby pressing the elastic valve body D32 into the air intake mounting seat D11, limiting the movement of the elastic valve body D32, and preventing the elastic valve body D32 from falling off from the air intake mounting seat D11 and failing to cover the vent D12.

[0091] Further explanation: it also includes a filter mechanism D4, and a filter hole D412 is provided at the bottom of the filter mechanism D4, and the filter hole D412 is used for gas to enter the filter mechanism D4; the filter mechanism D4 is installed at the bottom of the one-way exhaust mechanism D3, and the one-way exhaust mechanism D3 and the filter mechanism D4 are connected, and the elastic valve body D32 can be deformed and bulged, so that the gas enters the air intake structure D through the filter mechanism D4, the vent D12 and the exhaust hole D322 in sequence.

[0092] In the prior art, during the juicing process, fruit and vegetable particles in the juicer easily enter the exhaust system of the juicer, thereby blocking the exhaust system and causing the exhaust system to exhaust unsmoothly. The technical solution uses the filtering mechanism D4 to block the fruit and vegetable particles in the juicer from entering the air intake structure D, so as to avoid the fruit and vegetable particles from blocking the air intake structure D, so that the air intake structure D can maintain smooth air intake.

[0093] Further explained, the filtering mechanism D4 includes a cap-shaped shell D41 and a filter assembly D42. The cap-shaped shell D41 can be detachably mounted on the mounting seat D11. A filter hole D412 is provided at the bottom of the cap-shaped shell D41. The filter hole D412 is connected to the vent hole D12. The filter assembly D42 is arranged in the cap-shaped shell D41.

[0094] The cap-shaped shell D41 and the filter assembly D42 cooperate with each other to prevent the fruit and vegetable particles in the juicer from entering the air intake structure D, so as to avoid the fruit and vegetable particles from clogging the air intake structure D, so that the air intake structure D can maintain smooth air intake. The cap-shaped shell D41 is used to block fruit and vegetable particles with large particle sizes outside, and the filter assembly D42 is used to block fruit and vegetable particles with smaller particle sizes inside the cap-shaped shell D41. Graded filtering and blocking is adopted to prevent fruit and vegetable particles with large particle sizes from directly adhering to the filter assembly D42 and clogging the filter assembly D42, so as to reduce the frequency of replacing or cleaning the filter assembly D42. More preferably, the detachable installation includes any one of a threaded connection or a snap-on connection.

[0095] Preferably, the filter assembly D42 includes a first filter D421 and a filter fixing member D422, wherein the filter fixing member D422 is interference fit with the inner wall of the cap-shaped shell D41, and the filter fixing member D422 is provided with a ventilation cavity D4221 connected to the filter hole D412, and a filter installation groove D423 is provided in the ventilation cavity D4221, and the first filter D421 is installed in the filter installation groove D423. The filter fixing member D422 is used to fix the first filter D421 in the cap-shaped shell D41, and specifically, the filter fixing member D422 is cylindrical, and the outer wall of the filter fixing member D422 has a convex edge, and the convex edge is used to make the filter fixing member D422 and the inner wall of the cap-shaped shell D41 have an interference fit. In addition, the filter fixing member D422 can also be a sealing gasket or the like.

[0096] Preferably, the air intake mounting seat D11 is provided with an annular sealing gasket D13, and a second filter screen D14 is further provided between the annular sealing gasket D13 and the air vent D12; the cap-shaped housing D41 presses the annular sealing gasket D13 and the second filter screen D14 against the air intake mounting seat D11. By providing the second filter screen D14 on the air intake mounting seat D11, a second filtering and blocking is performed, thereby preventing fruit and vegetable particles from clogging the air intake structure D, so that the air intake structure D can maintain smooth air intake.

[0097] Further, the exhaust structure C includes a surface cover C1 and a top cover C2, the surface cover C1 covers the top of the cover body A, and the edge of the surface cover C1 is flush with the opening edge of the cover body A, and the surface cover C1 is concave downward to form a water collection chamber;

[0098] A support seat C11 is protrudingly provided on the upper surface of the water collecting chamber, the top cover C2 is mounted on the surface cover C1 through the support seat C11, and the chamber of the support seat C11 is communicated with the inner cavity of the cover body A;

[0099] The opening edge of the support seat C11 is provided with a plurality of convex strips C111, and the convex strips C111 are arranged at intervals. The bottom of the top cover C2 abuts against the convex strips C111, and an exhaust channel C101 is left between the opening edge of the support seat C11, and the exhaust channel C101 is connected to the chamber of the support seat C11.

[0100] In order to realize the vacuum performance normally, it is necessary to discharge the gas in the vacuum container into the atmosphere. The exhaust structure in the prior art is generally an exhaust hole. Since the exhaust hole in the prior art is generally arranged on the surface of the juicer, the appearance of the juicer product is not beautiful and generous, and the exhaust hole is easy to get water, which is not conducive to the realization of the waterproof performance of the juicer; although some juicer manufacturers will set a cover at the opening of the exhaust hole to open or close the exhaust hole in order to prevent water from entering the juicer base or the sealing cover through the exhaust hole, the existing cover is generally protruding from the surface of the juicer, resulting in the appearance of the juicer not being smooth and flat, and the appearance is not beautiful and generous, and the protruding structure is easy to hide dirt, which is not conducive to the cleaning of the juicer.

[0101] The vacuum cover of the technical solution is as follows: Figure 7 As shown, the support seat C11 is provided with convex strips C111, and the convex strips C111 are arranged at intervals at the opening edge of the support seat C11, so that an exhaust channel C101 is left between the top cover C2 and the support seat C11, and the gas staying in the inner cavity of the vacuum upper cover can flow into the atmosphere through the exhaust channel C101. Since the exhaust channel C101 of the present technical solution is arranged between the top cover C2 and the support seat C11, from the appearance of the vacuum upper cover, the user only sees the installation gap between the top cover C2 and the support seat C11, and will not notice the existence of the exhaust channel C101 here. Therefore, the exhaust channel C101 of the present technical solution has greater concealment, which effectively ensures the normal realization of the vacuum function and improves the aesthetics of the appearance of the vacuum upper cover.

[0102] Furthermore, the top cover C2 is installed by protruding the support seat C11 on the top of the surface cover C1. When water droplets fall on the top of the surface cover C1, they are helpful to accumulate in the water collecting chamber, thereby preventing water from flowing along the top of the surface cover C1 into the exhaust channel C101 between the top cover C2 and the support seat C11. While ensuring the normal realization of the exhaust function, it is also helpful to improve the waterproof performance of the vacuum upper cover and prevent water from flowing from the exhaust channel C101 into the inner cavity of the vacuum upper cover, thereby damaging the electronic components arranged in the inner cavity.

[0103] Preferably, the side of the top cover C2 is inclined from top to bottom, and the lower surface of the top cover C2 protrudes from the top of the support seat C11. The side of the top cover C2 is inclined from top to bottom, and the lower surface of the top cover C2 protrudes from the top of the support seat C11. When water stays on the top cover C2, it is more conducive to guiding the water to flow along the inclined surface of the top cover C2 to the water collection chamber, which is conducive to improving the waterproofness of the connection gap.

[0104] Preferably, the top of the support seat C11 is higher than the edge of the surface cover C1. The structural design of the water collection chamber in the technical solution makes it easy for water to accumulate inside the surface cover C1. In order to further prevent water from entering the interior of the vacuum upper cover from the connection gap between the support seat C11 and the top cover C2, the technical solution also makes the top of the support seat C11 higher than the top of the water collection chamber. When water accumulates in the water collection chamber, the vertical height from the accumulation level to the connection gap is effectively increased. Even if the water collection chamber is full of water, it will not enter the interior of the waterproof cover structure from the connection gap between the support seat C11 and the top cover C2, effectively ensuring the waterproof performance of the vacuum upper cover of the juicer.

[0105] To further explain, the vacuum device B is externally covered with a shock-absorbing sleeve B4.

[0106] In one embodiment of the present technical solution, Figure 2-5 As shown, the outside of the vacuum device B is tightly covered with a shock-absorbing sleeve B4 (the shock-absorbing sleeve B4 in this embodiment is silicone, and in other embodiments it can be soft rubber of other materials). The shock-absorbing sleeve B4 can absorb the vibration generated when the vacuum device B is working, thereby effectively reducing the noise generated when the vacuum device B is working and improving the user experience.

[0107] Preferably, a pressing portion B11 is provided at the bottom of the cover C1, and the bottom of the pressing portion B11 is pressed against the shock-absorbing sleeve B4. Pressing refers to applying pressure against each other. In different embodiments, the pressing portion B11 can be block-shaped, plate-shaped, strip-shaped, or other irregular shapes. It is only necessary to ensure that the bottom of the pressing portion B11 fits the top of the shock-absorbing sleeve B4, so that the pressing portion B11 can be pressed against the shock-absorbing sleeve B4, so that the vacuum device B tightly sleeved in the shock-absorbing sleeve B4 can be effectively fixed. At the same time, since the shock-absorbing sleeve B4 itself is made of soft rubber material, the pressing portion B11 is in flexible contact when pressed down on the shock-absorbing sleeve B4, and the pressing portion B11 is not directly pressed against the outside of the vacuum device B. By indirectly pressing the vacuum device B in this way, the vibration generated by the vacuum device B during operation is prevented from being directly transmitted to the pressing portion B11 through its outer shell, thereby reducing the vibration of the juicer as a whole.

[0108] Preferably, the pressing part B11 is plate-shaped, and a pressing edge B111 is provided at the bottom of the pressing part B11, and the pressing edge B111 presses against the shock-absorbing sleeve B4. The pressing part B11 is preferably plate-shaped, and the plate-shaped pressing part B11 is vertically arranged to ensure that the pressing edge B111 at the bottom of the pressing part B11 presses against the top of the shock-absorbing sleeve B4. Because the contact area between the pressing edge B111 and the shock-absorbing sleeve B4 is small, when the pressing part B11 presses against the shock-absorbing sleeve B4, a large pressure is generated, thereby effectively pressing and fixing the vacuum device B. In this embodiment, the pressing part B11 is configured to be a straight plate and a U-shaped plate. The pressing part B11 includes a straight plate and a U-shaped plate, wherein the bottom of the straight plate has a pressing edge B111, and the bottom of the U-shaped plate has two pressing edges B111, and the three pressing edges are respectively pressed against the left side, the middle and the right side of the top of the shock-absorbing sleeve B4, so that the shock-absorbing sleeve B4 can be effectively pressed, and then the vacuum device B can be effectively pressed and fixed. In addition, the use of the plate-shaped pressing part B11 can save the manufacturing material of the pressing part B11, thereby reducing the weight of the fixed structure as a whole, and finally reducing the weight of the juicer using the fixed structure, making the juicer more portable.

[0109] Preferably, the shock-absorbing sleeve B4 is provided with heat dissipation holes B41. Since the vacuum device B generates heat when working, and the shock-absorbing sleeve B4 is covered on the outside of the vacuum device B, if the heat of the vacuum device B is difficult to dissipate, it may cause the vacuum device B to fail to work. Therefore, the heat dissipation holes B41 are opened in the shock-absorbing sleeve B4 so that the heat of the vacuum device B when working can be dissipated through these heat dissipation holes B41, ensuring that the vacuum device B can be wrapped by the shock-absorbing sleeve B4 to achieve shock absorption, and the heat of the vacuum device B when working can be dissipated, and the gravity of the shock-absorbing sleeve B4 can be reduced. The shape and number of the heat dissipation holes B41 can be determined according to actual conditions. For example, in this embodiment, the top and top of the shock-absorbing sleeve B4 are provided with long strip-shaped heat dissipation holes B41.

[0110] Preferably, the cover body A includes a mounting frame B21, which is located inside the cover body A, the vacuum device B is fixed to the mounting frame B21, and the outer wall of the shock-absorbing sleeve B4 is in contact with the inner wall of the mounting frame B21. Since the surface cover C1 covers the cover body A, the bottom of the pressing portion B11 presses against the shock-absorbing sleeve B4 to limit the vertical movement of the vacuum device B. In addition, the mounting frame B21 is provided inside the cover body A, the vacuum device B is embedded in the mounting frame B21, and the outer wall of the shock-absorbing sleeve B4 is in contact with the inner wall of the mounting frame B21. The mounting frame B21 can limit the horizontal movement of the vacuum device B. When the vertical and horizontal movements of the vacuum device B have been limited, the vacuum device B can be stably fixed inside the cover body A.

[0111] By embedding the vacuum device B into the installation frame B21 and fixing it, it is possible to avoid using screws or other fixing parts to fix the vacuum device B. Therefore, the fixing method of the vacuum device B in this embodiment is simpler. To disassemble the vacuum device B, it is only necessary to take the vacuum device B upwards without any additional tools. Furthermore, the actual shape of the installation frame B21 can be determined according to the actual situation. It is only necessary to ensure that the outer wall of the shock-absorbing sleeve B4 is in contact with the inner wall of the installation frame B21. For example, the installation frame B21 in this embodiment includes a first frame B211 and a second frame B212.

[0112] Preferably, the inner wall of the mounting frame B21 is provided with a support portion B201, and the bottom of the shock-absorbing sleeve B4 is placed on the top of the support portion B201. The support portion B201 can be block-shaped, plate-shaped, strip-shaped or other irregular shapes, and it is only necessary to ensure that the bottom of the shock-absorbing sleeve B4 is placed on the top of the support portion B201, so that the vacuum device B is separated from the bottom of the cover body A.

[0113] Since in actual application, the fixed structure is used in the cup cover of the juicer, the vacuum device B is separated from the bottom of the cover body A. On the one hand, it can provide more positions for the installation of other parts of the juicer, and on the other hand, it can avoid the contact between the vacuum device B and other parts of the juicer, thereby reducing the possibility of vibration transmission through other parts of the juicer when the vacuum device B is working, and also playing a shock-absorbing effect.

[0114] In this embodiment, the support part B201 is plate-shaped and vertically arranged. The top area of ​​the support part B201 in contact with the shock-absorbing sleeve B4 is small, so when the shock-absorbing sleeve B4 is placed on the top of the support part B201, a large pressure will be generated, and the bottom of the shock-absorbing sleeve B4 and the contact surface with the support part B201 will be concave, so that the vacuum device B can be placed more stably.

[0115] A juicer includes a juicer body and the above-mentioned vacuum upper cover, wherein the vacuum upper cover 100 is installed on the juicer body 200 .

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way.
