[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0034] like Figure 1 and Figure 2 As shown, an electric device 100 provided in one embodiment of the present invention includes a housing 10 , a flow guide component 30 , a brewing component 40 , a pumping device and a cover 60 .

[0035] The housing 10 has an open end and a receiving chamber 142 connected to the open end, and the receiving chamber 142 is used to carry a liquid medium. The flow guide component 30 is fixedly disposed in the receiving chamber 142, and the flow guide component 30 has a flow guide channel extending along its longitudinal direction, and the flow guide channel is connected to the receiving chamber 142. The brewing component 40 is rotatably accommodated in the receiving chamber 142 relative to the housing 10, and the brewing component 40 has a mixing chamber 421 for placing the substance to be brewed. The pumping device is connected to the housing 10 to provide a mixing force to mix the liquid medium flowing into the flow guide channel in the receiving chamber 142 with the substance to be brewed. The cover body 60 can detachably cover the opening of the housing 10 to close the receiving chamber 142.

[0036] In some embodiments, the housing 10 includes a base 12 and a shell 14, the base 12 has a supporting side 127 for supporting the base 12 as a whole on a supporting surface and a mounting side 128 opposite to the supporting side 127, the shell 14 is generally a hollow structure with both ends through, and its bottom end is covered on the mounting side 128 of the base 12, and the above-mentioned open end is the top of the shell 14, that is, an opening is opened at the top of the shell 14.

[0037] It should be noted that the support surface refers to a surface for placing the electric device, such as a desktop, a kitchen countertop, etc. At the same time, the structure placed in the vertical direction in the above embodiment means that the electric device is placed in the vertical direction when in use, that is, the housing 14 is also in the vertical direction, and the bottom and top of the housing 14 are the two ends of the housing 14 in the vertical direction. Of course, in actual applications, the electric device usually needs to be placed vertically even when not in use.

[0038] Furthermore, the base 12 is roughly cylindrical, and the base 12 includes a detachable lower base 122 and an upper base 124, the upper base 124 covers the lower base 122 to form a base 12 with an installation cavity 126, and the shell 14 is similar to a combination of two frustums, and the radial dimensions of the two ends of the shell 14 are larger than the radial dimensions in the middle, that is, the middle is concave, and the radial dimension of the bottom end of the shell 14 is larger than the radial dimension of the top end of the shell 14.

[0039] Since the radial dimension of the base 12 is relatively large, in order to match it, the radial dimension of the bottom end of the shell 14 is larger than that of the top end. Of course, such a design also ensures that the lower size of the entire electric device is larger than the upper size, thereby improving stability.

[0040] See also Figure 2In some embodiments, the electric device further includes a support member 20, which is disposed in the inner cavity of the housing 10, and the support member 20 is sealed and fixedly connected to the inner wall of the housing 10 to form the above-mentioned accommodating cavity 142 with the housing 10. Of course, in some embodiments, the support member 20 can also be integrally disposed with the housing 10, that is, the support member 20 is a part of the housing 10, and the function of the support member 20 can also be achieved.

[0041] Furthermore, the support member 20 is disposed in the housing 14 and is sealed and fixedly connected to the inner wall of the housing 14, so that a receiving cavity 142 is formed on the side of the support member 20 away from the base 12 and the housing 14, and the receiving cavity 142 is communicated with the open end of the housing 10. The support member 20 and the inner wall of the housing 14 are sealed and connected by providing a sealing ring 81 between the two.

[0042] The accommodating chamber 142 is actually a space for preparing the substance to be prepared. In order to ensure that the liquid in the accommodating chamber 142 does not splash out during preparation, a cover body 60 is required to cover the opening. However, after the cover body 60 is connected to the shell 14, the opening is not sealed. A certain gap can still exist between the cover body 60 and the inner wall of the shell 14 to facilitate pouring out the prepared beverage in the accommodating chamber 142 without removing the cover body 60.

[0043] At the same time, in order to further facilitate pouring out the prepared beverage in the accommodating chamber 142, a pointed spout for guiding the flow is also provided at the top of the shell 14. Of course, the pointed spout is the same as the pointed spout provided for convenience in commonly used kettles and other equipment, so it will not be described in detail.

[0044] Please also see Figure 3 and Figure 4 In some embodiments, a first snap-fit ​​portion 144 is disposed at the top of the shell 14, and a second snap-fit ​​portion 62 is disposed at the cover 60. The first snap-fit ​​portion 144 and the second snap-fit ​​portion 62 can be engaged with each other so that the cover 60 can be detachably covered on the open end of the shell 14.

[0045] Furthermore, the number of the first clamping parts 144 and the second clamping parts 62 is the same, and both are at least two, to ensure stable clamping, so that the cover body 60 can be stably connected to the shell 14. In practical applications, the number of the first clamping parts 144 and the second clamping parts 62 is three, and they are evenly spaced along the circumferential direction of the shell 14 and the cover body 60.

[0046] Specifically, the first clamping portion 144 is a horizontally extending plate-like structure, and the second clamping portion 62 includes an inclined plate 622, a vertical limit plate 624 and a horizontal limit plate 626 that are interconnected. The inclined plate 622 is inclined relative to the horizontal direction, the vertical limit plate 624 extends in the horizontal direction, and the horizontal limit plate extends in the vertical direction.

[0047] Among them, the end of the inclined plate 622 with a higher horizontal height is connected to the vertical limit plate 624, the bottom end of the horizontal limit plate 626 is fixedly connected to the end of the vertical limit plate 624 away from the inclined plate 622, and when the cover body 60 covers the open end of the shell 14, the horizontal height of the vertical limit plate 624 is lower than the horizontal height of the first clamping part 144, and the horizontal height of the top end of the horizontal limit plate 626 is higher than the height of the bottom end of the first clamping part 144.

[0048] In this way, when the cover 60 covers the open end, the horizontal heights of the inclined plate 622 and the vertical limit plate 624 are lower than the first clamping portion 144. The cover 60 can be rotated so that the first limit plate 144 is located above the vertical limit plate 624 through the inclined plate 622 to limit the cover 60 from moving in the vertical direction. At the same time, the horizontal limit plate 626 is located at one end of the vertical limit plate 624, and the horizontal height of the top end is higher than the height of the bottom end of the first clamping portion 144, which makes the cover 60 rotate, so that the first clamping portion 144 will be relatively rotated to one end of the vertical limit plate 624 and abut against the horizontal limit plate 626, thereby limiting the first clamping portion 144 from continuing to rotate relatively, and thus limiting the rotation of the cover 60. At this time, the cover 60 is in a closed state.

[0049] Among them, the mixing chamber 421 is used to place the substance to be brewed, and the above-mentioned pumping device provides a mixing force to mix the liquid medium in the diversion channel with the substance to be brewed. In fact, it is a lifting force to lift the liquid medium in the diversion channel along the diversion channel and transport it to the mixing chamber 421 to mix with the substance to be brewed. Because the liquid medium will be mixed with the substance to be brewed after being transported to the mixing chamber 421, it is called a mixing force in the above-mentioned embodiment.

[0050] See also Figure 2In some embodiments, the pumping device includes a driving member 51 and a transmission assembly, and a lifting member 53 connected to the transmission assembly, which are all connected to the housing 10. The transmission assembly is connected to the output shaft of the driving member 51, and is used to transmit the rotation output of the output shaft of the driving member 51 to the lifting member 53. The lifting member 53 is arranged in the guide channel. When the lifting member 53 rotates along the preset direction with the output shaft of the driving member 51, it can provide a mixing force to mix the liquid medium in the guide channel with the substance to be brewed. Furthermore, the brewing assembly 40 is also connected to the transmission assembly so that it can rotate along the preset direction with the transmission assembly. The substance to be brewed is placed in the mixing chamber 421 of the brewing component 40, and a liquid medium is injected into the accommodating chamber 142 at the same time, and the liquid medium level should at least immerse part of the diversion channel. When the electric device is running, the lifting member 53 lifts the liquid medium immersed in the diversion channel to the mixing chamber 421. When the brewing component 40 rotates, the liquid medium and the substance to be brewed are mixed, and the accommodating chamber 142 and the diversion channel are connected. The mixed liquid solution will also be lifted by the lifting member 53 in the diversion channel to the brewing component 40. In this way, the continuous circulation makes the substance to be brewed and the liquid medium mix more fully, effectively improves the brewing effect, thereby improving the taste of the formed beverage, which is easy to be accepted by users and is conducive to promotion.

[0051] In some embodiments, the transmission assembly includes a transmission member 522, the driving member 51 is arranged on the base 12, the transmission member 522 is arranged in the vertical direction and is movable in the vertical direction, the first end of the transmission member 522 is transmission-connected to the output shaft of the driving member 51 so as to rotate along the preset direction with the output shaft of the driving member 51, and the first end of the transmission member 522 extends in the vertical direction into the accommodating cavity 142.

[0052] Furthermore, the transmission member 522 extends into the diversion channel to match with the lifting member 53. It should be explained that the transmission member 522 extends into the diversion channel, which does not limit the second end of the transmission member 522 extending into the accommodating cavity 142 to be only located in the diversion channel, but means that the transmission member 522 enters the diversion channel.

[0053] See also Figure 2 In some embodiments, the electric device also includes a first mating piece 524 and a second mating piece 525, the first mating piece 524 is fixedly connected to the output shaft of the driving member 51, the second mating piece 525 is arranged at the first end of the transmission member 522, and the second mating piece 525 is slidably connected to the first mating piece 524 along the moving direction of the transmission member 522, and meshes with the first mating piece 524 in the circumferential direction.

[0054] In practical applications, the output shaft of the driving member 51 passes through the mounting cavity 126 and extends from the mounting side 128 to be fixedly connected to the first mating member 524, and the first mating member 524 and the second mating member 525 are splined to ensure that the second mating member 525 can rotate with the first mating member 524 and can also be movably connected to the first mating member 524 in the vertical direction. Specifically, the first mating member 524 and the second mating member 525 are both clutches.

[0055] Please also see Figure 6 and Figure 7 In some embodiments, the lifting member 53 includes a lifting body 532 and a plurality of lifting blades 534. The transmission member 522 is passed through the lifting body 532 to drive the lifting body 532 to rotate, and the plurality of lifting blades 534 are installed on the peripheral side of the lifting body 532 to provide a lifting force to lift the liquid medium when the lifting body 532 rotates.

[0056] Furthermore, the lifting body 532 is a hollow truncated cone structure, and a hole matching with the transmission member 522 is provided at one end of the bottom surface of the truncated cone structure with a smaller area.

[0057] In some embodiments, the radial dimension of the lifting body 532 gradually increases from bottom to top, which makes the dimension of the lifting blade 534 expanded in the horizontal direction gradually increase from bottom to top. When the lifting member 53 rotates, the liquid medium is driven to rotate and lift by the lifting blade 534, which can also be understood as the liquid medium rotating and rising from bottom to top along the lifting blade 534, and the lifting blade 534 expands in the horizontal direction with the increase of height, and the liquid medium always fills the space where the entire lifting member 53 is located, combined with the gradually increasing size, that is to say, the liquid medium lifted from bottom to top will have an outward centrifugal force, but the liquid medium is restricted from continuing to expand in the guide channel, so the liquid medium can only move upward.

[0058] In this way, the lifting member 53 forms a certain centrifugal force on the liquid medium, and part of these centrifugal forces will be converted into lifting force for the liquid medium to rise, thereby increasing the lifting speed of the liquid medium, and also increasing the circulation speed and mixing speed, thereby improving the brewing effect.

[0059] In some embodiments, the lifting member 53 is an impeller, and the multiple blades on the impeller are spiral blades rotating around the central axis thereof, and the multiple spiral blades are evenly distributed along the circumferential direction, and the outer contour of the spiral blades corresponds to the shape of the guide channel. As shown in the figure, when the shape of the guide channel is not cylindrical, the overall shape of the impeller is also not cylindrical. In this way, it can be ensured that sufficient lifting force is provided when the impeller rotates in a preset direction.

[0060] In some embodiments, the blades of the impeller should be as close to the inner wall of the guide channel as possible. Furthermore, there is a preset gap between the outer surface of the blade and the inner wall of the guide channel, and the gap is 0.1 mm to 0.4 mm, so as to avoid friction between the outer surface of the blade and the inner wall while ensuring sufficient lifting force.

[0061] In some embodiments, the line connecting the highest point and the lowest point on the outer surface of the same spiral blade is at an angle to the vertical direction. In practical applications, the angle between the line connecting the two points and the central axis of the impeller is an acute angle. Specifically, the angle ranges from 5 degrees to 60 degrees.

[0062] In some embodiments, the electric device further includes a control switch 56, which is connected to the housing 10 and is used to control the on / off of the external power supply and the driving member 51. When the cover 60 covers the open end of the housing 10, the transmission assembly is controlled to move relative to the housing 10, and the control switch 56 is triggered to be electrically connected to the driving member 51 during the movement.

[0063] In this way, only when the cover body 60 covers the opening of the shell 14, the control switch 56 can be electrically connected to the driving member 51, so that the control switch 56 can control the on and off of the external power supply and the driving member 51, and then realize the control of the operation of the driving member 51, effectively avoiding the situation where the user accidentally starts the device when the cover is not closed, and is less likely to cause use accidents, thereby ensuring the safety of use and improving safety performance.

[0064] Furthermore, the transmission assembly includes a trigger end and a controlled end, the trigger end has a connection position for triggering the control switch 56 and a disconnection position for being separated from the control switch 56, and the controlled end controls the trigger end to switch between the connection position and the disconnection position. That is, when the controlled end is in the connection position, the control switch 56 is electrically connected to the driving member 51, and when the controlled end is in the disconnection position, the control switch 56 is disconnected from the driving member 51.

[0065] Specifically, the controlled end of the transmission assembly extends into the accommodating cavity, and the cover body 60 presses down the controlled end when covering the opening, and drives the trigger end to switch from the disconnected position to the connected position.

[0066] In some embodiments, the transmission assembly also includes a linkage member 526, which is connected to the transmission member 522. The second end of the transmission member 522 extends to the top opening of the shell 14. When the cover body 60 covers the opening, it presses the second end of the transmission member 522 in the vertical direction to make the transmission member 522 move in the vertical direction relative to the shell 10, and the linkage member 526 can move synchronously with the transmission member 522 and trigger the control switch 56 to be electrically connected to the drive member 51.

[0067] In combination with the above embodiment, it needs to be explained that the transmission component triggers the electrical connection between the control switch 56 and the driving member 51 through the trigger end during the movement, and the second end of the transmission member 522 is pressed by the cover body 60, and the linkage member 526 moves synchronously with the transmission member 522 to trigger the control switch 56 to be electrically connected with the driving member 51. Therefore, the second end of the transmission member 522 is equivalent to the controlled end in the above embodiment, and the trigger end in the above embodiment is located on the linkage member 526.

[0068] Therefore, the corresponding linkage member 526 has the above-mentioned connection position and disconnection position, that is, when the linkage member 526 is in the connection position, the control switch 56 is electrically connected to the driving member 51, and when the linkage member 526 is in the disconnection position, the control switch 56 is disconnected from the driving member 51, and when the control switch 56 is electrically connected to the driving member 51, the control switch 56 can control the operation of the driving member 51. In this way, the linkage member 526 is driven to switch between the connection position and the disconnection position by the up and down movement of the transmission member 522.

[0069] At the same time, the movable member 522 can be moved in the vertical direction due to the cooperation between the first matching member 524 and the second matching member 525, and when the linkage member 526 switches between the connected position and the disconnected position, the following conditions exist between the first matching member 524 and the second matching member 525:

[0070] First, the first mating member 524 and the second mating member 525 are always circumferentially meshed with each other; second, when the linkage member 526 is in the disconnected position, there is a certain distance between the first mating member 524 and the second mating member 525 in the vertical direction, and the transmission member 522 moves downward, driving the linkage member 526 and the second mating member to move downward respectively, and before the linkage member 526 moves down to the connected position, the second mating member 525 begins to circumferentially mesh with the first mating member 524; third, similar to the second situation, but the second mating member 525 begins to circumferentially mesh with the first mating member 524 after the linkage member 526 moves down to the connected position.

[0071] In some embodiments, the linkage member 526 includes a linkage portion 5242 and a trigger portion 5244. The linkage portion 5242 is movably connected to the transmission member 522 along the vertical direction. The trigger portion 5244 is disposed on the base 12 and connected to the linkage portion 5242 to move along the vertical direction with the linkage portion 5242, and is used to trigger the control switch 56 to be electrically connected to the driving member 51. That is, the trigger end is located at the trigger portion 5244.

[0072] When the linkage member 526 is located at the connecting position, the trigger portion 5244 is connected between the control switch 56 and the driving member 51 . When the linkage member 526 is located at the disconnecting position, the trigger portion 5244 is disconnected from the control switch 56 .

[0073] See also Figure 8 and Fig. 9 Furthermore, the support member 20 includes a first support portion 22 and a guide portion 24. The first support portion 22 is circumferentially sealed and fixedly connected to the inner wall of the shell 14. The guide portion 24 is fixedly connected to the side of the first support portion 22 facing the base 12 and extends in the vertical direction. The linkage member 526 is provided with a guide hole matching the guide portion 24. The guide hole is slidably mounted on the outer periphery of the guide portion 24 along the moving direction of the linkage member so that the linkage member 526 can be moved in the vertical direction.

[0074] Specifically, the guide portion 24 is a plurality of guide posts, and a plurality of guide holes are provided on the corresponding linkage member 526 to improve the stability of the vertical movement of the linkage member 526 .

[0075] In some embodiments, an outer circumferential surface of the first support portion 22 is provided with an external thread, and a bottom end of the corresponding shell 14 is provided with a matching internal thread, so that the first support portion 22 is threadedly connected to the shell 14 .

[0076] In some embodiments, the linkage portion 5242 is located on a side of the support member 20 close to the base 12, that is, there is a certain space between the support member 20 and the mounting side 128 of the base 12, and the linkage portion 5242 is movably disposed in the space along the vertical direction.

[0077] Furthermore, the trigger portion 5244 is movably disposed in the installation cavity 126 along the vertical direction, the linkage portion 5242 is disposed on the installation side 128 , and one end of the linkage portion 5242 extends into the installation cavity 126 and is connected to the trigger portion 5244 .

[0078] In some embodiments, the linkage portion 5242 includes a first linkage structure 5241 and a second linkage structure 5243, the first linkage structure 5241 is movably connected to the transmission member 522 along the vertical direction, the second linkage structure 5243 is fixedly connected to the first linkage structure 5241, and one end of the second linkage structure 5243 away from the first linkage structure 5241 extends into the installation cavity 126.

[0079] It needs to be explained that if Figure 2 and Figure 3 As shown, the first linkage structure 5241 is a disc-shaped structure with a middle protrusion, and the middle protrusion is for movably connecting to the transmission member 522, while the second linkage structure 5243 is fixedly connected to the edge of the first linkage structure 5241. Moreover, the second linkage structure 5243 extending into the installation cavity 126 does not mean that all of the second linkage structure 5243 extends into the installation cavity 126, but it can be a part of the second linkage structure 5243.

[0080] At the same time, the second linkage structure 5243 extends into the mounting cavity 126 and can be as follows: Figure 2 As shown, the mounting side 128 of the base 12 has a protrusion, and the cavity at the protrusion is also a part of the mounting cavity 126 . The second linkage structure 5243 extends into the cavity of the protrusion, and can also be regarded as extending into the mounting cavity 126 .

[0081] In addition, in some other embodiments, the trigger portion 5244 may partially extend out of the mounting cavity 126 to connect with the linkage portion 5242 , thereby realizing the connection between the control switch 56 and the driving member 51 and the linkage between the up and down movement of the transmission member 522 .

[0082] In some embodiments, the linkage member 526 also includes a limiting portion 5246, which is fixedly connected to the support member 20 and located between the support member 20 and the base 12, and is used to limit the linkage member 5242 between the limiting portion 5246 and the support member 20.

[0083] In some embodiments, the linkage portion 5242 is provided with a guide hole matching the guide portion 24, and the guide portion 24 is passed through the guide hole so that the linkage portion 5242 can stably move in the vertical direction.

[0084] In actual application, the limiting portion 5246 is fixedly connected to the guide portion 24 to limit the linkage portion 5242 between the first support portion 22 and the limiting portion 5246, and the limiting portion 5246 is fixedly connected to one end of the guide portion 24 away from the first support portion 22 by a screw 99.

[0085] See also Fig.10 In some embodiments, the electric device also includes an elastic member 70, which is connected between the base 12 and the linkage member 526, and is used to provide a pre-tightening force that causes the linkage member 526 to have a tendency to move upward, so as to ensure that after the cover body 60 is detached, the elastic member 70 will lift the linkage member 526 and the transmission member 522, thereby disconnecting the control switch 56 and the drive member 51 to ensure safety.

[0086] Further, the elastic member 70 is disposed in the mounting cavity 126, and the elastic member 70 is connected between the base 12 and the trigger portion 5244. Of course, the elastic member 70 can also be disposed on the mounting side 128, and connected between the base 12 and the linkage portion 5242. Specifically, the elastic member 70 is a spring.

[0087] In some embodiments, the trigger portion 5244 includes a third linkage structure 5247, a reset structure 5248 and a trigger structure 5249 that are relatively fixedly connected, the end of the second linkage structure 5243 away from the first linkage structure 5241 is connected to the third linkage structure 5247, the reset structure 5248 is connected to the elastic member 70, and the trigger structure 5249 can be used to connect the control switch 56 and the driving member 51.

[0088] It can be understood that the trigger end is one end of the trigger structure 5249, and there can be many ways to connect the elastic member 70 and the reset structure 5248, as long as it can be ensured that after the elastic member 70 is connected to the reset structure 5248, an upward pre-tightening force can be directly and indirectly provided to the trigger structure 5249 and the transmission member 522, so that after the cover body 60 is removed, the trigger structure 5249 and the transmission part can move upward, which can not only disconnect the control switch 56 and the drive member 51, but also ensure that the functions of the transmission member 522 and the linkage member 526 can continue to be realized when the cover body 60 is installed next time.

[0089] In some embodiments, in order to prevent the liquid medium from affecting the control switch 56, a sealing ring 82 and a sealing gasket 83 are provided at one end of the trigger portion 5244 extending into the cavity of the above-mentioned protrusion. At the same time, in order to install the sealing ring 82 and the sealing gasket 83, a ring rib for fixing the sealing ring 82 and the sealing gasket 83 is provided at a position on the inner wall of the installation cavity 126 corresponding to the protrusion of the above-mentioned base 12. The sealing gasket 83 directly abuts against the trigger portion 5244, and the outer side of the sealing ring 82 is fixed to the ring rib, and the inner side is fixedly connected to the trigger portion 5244, and can move up and down with the trigger portion 5244.

[0090] Specifically, the sealing ring 82 and the sealing gasket 83 are both connected to the third linkage structure 5247 .

[0091] In some embodiments, the pumping device further includes a power supply, and the control switch 56 is electrically connected to the power supply, and can be used to control the power supply to deliver power to the driving member 51 to operate the driving member 51. Further, the control switch 56 includes a control body 562 and a switch button 564 (see Figure 5 ), the control body 562 is electrically connected to the switch button 564, and the control body 562 is used to be electrically connected to the driving member 51, the control body 562 is arranged in the installation cavity 126, and the switch button 564 is installed on the side of the base 12 to facilitate user operation.

[0092] It should be noted that the switch button 564 can also be linked with the linkage member 526, that is, when the linkage member 526 is in the disconnected position, the switch button 564 cannot be kept on the on button, so as to prevent the user from accidentally turning on the switch when the cover body 60 is detached, and directly operating after the cover is closed. In this way, the safety of the electric device can be further improved.

[0093] Furthermore, the control switch 56, the power supply and the driving member 51 are all fixedly connected to the base 12. Specifically, the power supply is a device for connecting to an external power source, including structures such as wiring and a voltage adapter, and the driving member 51 is a driving motor.

[0094] It should be noted that the connection and control method between the control switch 56, the power supply and the driving member 51 is a conventional technology and can be deployed according to actual conditions, and the trigger part 5244 is only used to maintain or disconnect the three, rather than to control them.

[0095] See also Fig.11 In some embodiments, the transmission member 522 includes a first transmission part 5221, an intermediate part 5222, a second transmission part 5223, a third transmission part 5224 and a fourth transmission part 5225 which are fixedly connected in sequence along the vertical direction. The first transmission part 5221 is fixedly connected to the second matching member 525, the linkage part 5242 is sleeved on the intermediate part 5222, and one end of the second transmission part 5223 away from the third transmission part 5224 abuts against the linkage part 5242, so that the linkage part 5242 moves downward with the transmission member 522. When the cover body 60 is connected to the shell 14, the cover body 60 abuts against one end of the fourth transmission part 5225 away from the third transmission part 5224 to press down the transmission member 522.

[0096] Furthermore, a sealing gasket 84 is provided between one end of the second transmission part 5223 away from the third transmission part 5224 and the linkage part 5242 to prevent the liquid medium from flowing along the transmission member 522 to the driving member 51. Specifically, the transmission member 522 is a transmission shaft.

[0097] At the same time, it can be understood that in order to ensure stability, the radial dimension of the middle part 5222 should not be smaller than the radial dimension of the first transmission part 5221, and the linkage part 5242 is sleeved on the middle part 5222, and the second transmission part 5223 is abutted against the linkage part 5242, that is, the radial dimension of the second transmission part 5223 is larger than the radial dimension of the middle part 5222.

[0098] In some embodiments, one end of the first transmission part 5221 away from the middle part 5222 is provided with a thread, so that the first transmission part 5221 is threadedly connected to the second matching piece 525. Of course, the tightening direction of the threaded connection between the first transmission part 5221 and the second matching piece 525 is a preset direction to avoid the first transmission part 5221 and the first matching piece 524 from being disconnected during rotation.

[0099] In some embodiments, the third transmission part 5224 is used to drive the lifting member 53 and the brewing component 40 to rotate, that is to say, the lifting member 53 and the brewing component 40 are matched to the third transmission part 5224, so the cross-sectional shape of the third transmission part 5224 is a polygon, and the lifting member 53 and the brewing component 40 are provided with through holes matching their shapes. The first transmission part 5221, the middle part 5222, the second transmission part 5223 and the fourth transmission part 5225 do not need to drive other structures to rotate, so their cross-sectional shape can be circular, and the cross-sectional circles of the second transmission part 5223 and the fourth transmission part 5225 can be the inscribed circles of the cross-sectional polygon of the third transmission part 5224.

[0100] Of course, it needs to be explained that the first transmission part 5221, the second transmission part 5223 and the fourth transmission part 5225 are named transmission parts because these three transmission parts are used to transmit vertical movement, and are respectively transmitted to the second matching part 525, the linkage part 5242 and the cover body 60, while the third transmission part 5224 is used to cooperate with the lifting part 53 and the brewing component 40 and drive the lifting part 53 and the brewing component 40 to rotate.

[0101] In some embodiments, the support member 20 is provided with a bearing hole, and the second transmission part 5223 is penetrated through the bearing hole. Further, the pumping device further includes a bearing 57, which is provided at the bearing hole, and the second transmission part 5223 is supported by the cap bearing 57 to further improve the stability of the transmission member 522.

[0102] Please also see Figure 2 and Figure 4 In some embodiments, one end of the fourth transmission part 5225 away from the third transmission part 5224 is hemispherical, and a matching groove 64 is provided on the corresponding cover body 60. When the cover body 60 is covered on the shell 14, the end of the fourth transmission part 5225 away from the third transmission part 5224 extends into the matching groove 64.

[0103] In some embodiments, the brewing component 40 is relatively fixedly connected to the end of the transmission member 522 passing through the guide component 30, so as to rotate along the preset direction with the transmission member 522. It is understandable that the one end in the present invention is not limited to the end face, but a length range close to the end. Specifically, the brewing component 40 is relatively fixedly connected to the end of the third transmission part 5224 passing through the guide component 30.

[0104] See also Fig.12In some embodiments, the guide assembly 30 includes a first guide member 32, which is fixedly arranged relative to the housing 10, and has two ends through which a hollow is formed. Further, the first guide member 32 is fixedly connected to one side of the support member 20, and the first guide member 32 has a through channel that vertically penetrates two opposite ends of the first guide member 32, and the through channel is connected to the accommodating cavity 142. It can be understood that the first guide member 32 is fixedly connected to the side of the support member 20 away from the base 12.

[0105] In some embodiments, the flow guide assembly 30 also includes a second flow guide member 34 that is also fixed relative to the outer shell 10. The second flow guide member 34 is hollow at both ends and can be detachably mounted on the outside of the first flow guide member 32. The inner cavity of the second flow guide member 34 is connected to the inner cavity of the first flow guide member 32 to form the above-mentioned flow guide channel.

[0106] Furthermore, the second guide member 34 is arranged in the accommodating chamber 142 along the vertical direction, and the second guide member 34 has a guide chamber 342 and a liquid outlet 344 connected to the guide chamber 342, the liquid outlet 344 is connected to the mixing chamber 421, and the second guide member 34 is sleeved on one end of the first guide member 32 away from the support member 20, and the through channel is connected to the guide chamber 342 to form a guide channel for connecting the accommodating chamber 142 and the mixing chamber 421.

[0107] The lifting member 53 is disposed in the guide channel, and the lifting member 53 is an impeller. In fact, most of the impeller is located in the through-channel, and the top of the impeller extends out of the through-channel and enters the guide cavity 342 .

[0108] In some embodiments, the support member 20 includes a second support portion 26, which is fixedly connected to a side of the first support portion 22 away from the base 12, and the first guide member 32 is fixedly connected to a side of the second support portion 26 away from the first support portion 22, and the second support portion 26 extends into the guide channel, the radial dimension of the guide channel is larger than the radial dimension of the second support portion 26, and there is a preset gap between the end surface of the first guide member 32 close to one end of the first support portion 22 and the first support portion 22, so that the guide channel is connected to the accommodating cavity 142.

[0109] See also Fig.13 and Fig.14 In some embodiments, the first flow guide member 32 includes a liquid inlet portion 322 and a matching portion 326. The liquid inlet portion 322 is relatively fixedly connected to the second support portion 26, and the matching portion 326 is fixedly connected to a side of the liquid inlet portion 322 away from the support portion 20. The through channel penetrates the liquid inlet portion 322 and the matching portion 326, and the second flow guide member 34 is sleeved on the matching portion 326.

[0110] The above-mentioned through channel passes through the liquid inlet portion 322 and the matching portion 326, and the through channel is a channel inside the first flow guide member 32, that is, the liquid inlet portion 322 and the matching portion 326 are both provided with channels that pass through the opposite sides of themselves and are interconnected to form a through channel. The first flow guide member 32 can also be formed as a whole, and then processed separately to form the guide channel, the liquid inlet portion 322 and the matching portion 326.

[0111] Furthermore, the first flow guide also includes a connecting portion 324, which is located in the through channel and fixedly connected to the liquid inlet portion 322. The connecting portion 324 is fixedly connected to the second support portion 26 so that one end of the second support portion 26 away from the first support portion 22 extends into the through channel.

[0112] In practical applications, the radial dimension of the through channel is greater than the radial dimension of the second support portion 26, that is, the radial dimension of the liquid inlet portion 322 is definitely greater than the radial dimension of the second support portion 26, and there is a preset gap between the liquid inlet portion 322 and the first support portion 22, so that the through channel is connected to the accommodating cavity 142. Specifically, the connecting portion 324 is fixedly connected to the second support portion 26 by screws.

[0113] It should be noted that the preset gap between the liquid inlet portion 322 and the first support portion 22 can be that the side of the first support portion 22 away from the base 12 is a plane, and when the connecting portion 324 is connected to the second support portion 26 protruding from the first support portion 22, there is a preset gap between the liquid inlet portion 322 and the plane of the first support portion 22 away from the base 12; or the side of the first support portion 22 away from the base 12 has a recessed structure, the liquid inlet portion 322 corresponds to the recessed structure, and there is a preset gap between the liquid inlet portion 322 and the bottom surface of the recessed structure.

[0114] In addition, in some other embodiments, the connection between the connecting portion 324 and the second supporting portion 26 may be snap-fitted, where a snap-fit ​​interface is provided on the second supporting portion 26 and a snap-fitting protrusion is provided on the connecting portion 324 , and the snap-fitting protrusion is snapped into the snap-fitting interface.

[0115] In some embodiments, a sealed space is formed between the connecting portion 324 and the support member 20, and a sealing ring 85 is also provided in the sealed space to prevent the liquid in the accommodating cavity 142 from entering the space below the support member 20, thereby preventing the liquid from entering the base 12 and affecting the operation of the pumping device. Further, the pumping device also includes a bearing cover 58, which is disposed at the hole of the bearing 57 and is located between the sealing ring 85 and the bearing 57.

[0116] See also Fig.15 and Fig.16In some embodiments, the second guide member 34 includes a guide portion 341 and a liquid outlet portion 343. The guide portion 341 is sleeved on one end of the first guide member 32 away from the support member 20. The liquid outlet portion 343 is fixedly connected to the end of the guide portion 341 away from the first guide member 32. The guide portion 341 and the liquid outlet portion 343 are both hollow to form a guide cavity 342 connected to the through channel.

[0117] Furthermore, the inner cavity of the guide portion 341 is stepped, and the radial dimension of the inner cavity at one end of the guide portion 341 away from the liquid outlet portion 343 is larger than the radial dimension of the end of the guide portion 341 close to the liquid outlet portion 343. The end with the larger radial dimension is sleeved on the matching portion 326, and the end face of the matching portion 326 away from the liquid inlet portion 322 abuts against the step.

[0118] Specifically, the flow guiding portion 341 and the liquid outlet portion 343 are both substantially cylindrical, and the radial dimension of the flow guiding portion 341 is larger than the radial dimension of the liquid outlet portion 343 , and the connection between the flow guiding portion 341 and the liquid outlet portion 343 is arranged in an arc.

[0119] See also Figure 2 In some embodiments, the guide channel in the guide component 30 has a lifting section, a diversion section and a liquid outlet section arranged in sequence along its extension direction. The lifting section is connected to the accommodating chamber 142, and the liquid outlet section is connected to the mixing chamber 421. The diversion section is a part of the guide channel, and the diversion section is located between the lifting section and the liquid outlet section, which means that the diversion section connects the lifting section and the liquid outlet section.

[0120] Further, it can be understood that, as the name implies, the lifting section is the channel section that actively lifts the liquid medium, that is, the lifting member 53 is arranged in the lifting section in the guide channel, and the liquid outlet section is the channel section through which the liquid medium is discharged, and the liquid outlet hole 344 is connected to the liquid outlet section, that is, the liquid outlet hole 344 is used to connect the mixing chamber 421 and the liquid outlet section.

[0121] At the same time, it needs to be explained that the lifting section, the diversion section and the liquid outlet section divide the guide channel as a whole into three channel sections. The guide channel is formed by the combination of the first guide member 32 and the second guide member 34. However, the three channel sections are not distinguished according to the physical components, but are segmented according to the function. For example, the above-mentioned lifting member 53 actually partially extends out of the through channel of the first guide member 32, so the lifting section is not entirely located in the first guide member 32.

[0122] In some embodiments, the pumping device also includes a diverter 59, which is arranged in the diverter section of the guide channel, and the diverter 59 is fixed relative to the guide assembly 30. The diverter 59 divides the diverter section into multiple diverter channels extending in the vertical direction. The driving member 51 is controlled to drive the lifting member 53 to rotate in a preset direction to lift the liquid medium in the lifting section. After flowing through multiple diverter channels and the liquid outlet section in turn, it flows out into the mixing chamber 421. The multiple diverter channels not only stop the originally rotating liquid medium from rotating, but also reduce the space of the diverter section, thereby increasing the lifting speed of the liquid medium and improving the lifting effect.

[0123] Furthermore, the diverter member 59 is located above the lifting member 53, that is, the above-mentioned lifting body 532 from bottom to top can also be understood as being in the direction close to the diverter member 59. The diverter member 59 has a plurality of diverter grooves extending in the vertical direction. The diverter grooves cooperate with the inner wall of the guide channel to form a plurality of diverter channels so that the liquid medium can be lifted along the plurality of diverter channels.

[0124] In practical applications, the flow divider 59 is disposed in the flow guide cavity 342, and the flow divider 59 is relatively fixedly connected to the second flow guide 34. Specifically, the flow divider 59 is relatively fixedly connected to the flow guide portion 341. One of the functions of the flow divider 59 is to stop the rotating liquid medium from rotating, so the flow divider 59 will definitely not rotate like the lifting member 53, but is fixed relative to the flow guide portion 341.

[0125] See also Fig.17 and Fig.18 In some embodiments, the diverter member 59 includes a diverter body 592 and a plurality of diverter blades 594. The diverter body 592 is arranged in the vertical direction and is roughly cylindrical. The transmission member 522 passes through the diverter body 592. The diverter blades 594 extend longitudinally in the vertical direction. The plurality of diverter blades 594 are evenly spaced along the circumferential direction of the diverter body 592 and are clamped to the inner wall of the guide channel to fix the diverter member 59 relative to the guide assembly 30. At the same time, the diverter blades are arranged in the same manner to form a plurality of identical diverter channels.

[0126] Furthermore, the ends of each splitter blade 594 near the lifting member 53 are arc-shaped and bent in the same direction, and the bending direction of the ends of each splitter blade 594 is opposite to the rotation direction of the lifting member 53, that is, opposite to the preset direction. In this way, the liquid medium that is still rotating in the preset direction will enter the splitter channel along the arc-shaped ends, further improving the lifting speed.

[0127] In combination with the above embodiment, it should be explained that the lifting member 53 rotates to lift the liquid medium. The liquid medium will rotate continuously under the action of the lifting member 53, but the continuously rotating liquid medium will cause the liquid lifting speed to be reduced to a certain extent. Therefore, a diverter member 59 is provided. The diverter channel formed by multiple diverter blades 594 in the diverter member 59 stops rotating after the rotating liquid medium enters. After stopping rotating, the liquid medium only has an upward trend, which means that the lifting speed of the liquid medium is further improved.

[0128] Specifically, the number of the splitter blades 594 is the same as the number of the lifting blades 534 to further ensure the lifting effect of the liquid medium.

[0129] In some embodiments, the outer surface of each splitter blade 594 matches the inner wall shape of the guide portion 341, that is, the outer surface of each splitter blade 594 is in contact with the inner wall of the guide portion 341, which can ensure that the splitter 59 is fixed relative to the guide portion 341 and the lifting effect of the liquid medium.

[0130] It should be explained that the radial dimension of the guide portion 341 is larger than the radial dimension of the liquid outlet portion 343. When the diverter 59 is not set and the liquid medium is started to be lifted, the lifting member 53 rotates along the preset direction, first lifting the liquid medium to the upper space of the guide portion 341, and then entering the liquid outlet portion 343. However, the radial dimension of the guide portion 341 is larger and the lifting speed is slower. Therefore, the diverter 59 is set to reduce the space that the liquid medium needs to fill to a certain extent, thereby accelerating the lifting speed of the liquid medium and improving the lifting effect of the liquid medium.

[0131] In some embodiments, the end face at the top of the lifting member 53 and the end face at the bottom of the diverter body 592 are both annular surfaces, and are two annular surfaces of the same size. When the electric device is not started, the two annular surfaces can abut against each other. After starting the electric device, the lifting member 53 lifts the liquid medium, so it will be subjected to a downward force and move downward a certain distance. At this time, the end face at the bottom of the lifting member 53 abuts against the connecting portion 324 of the first guide member 32.

[0132] In some embodiments, there are multiple liquid outlet holes 344, and the multiple liquid outlet holes 344 are opened in the liquid outlet portion 343. The dispensing assembly 40 is sleeved on the liquid outlet portion 343, so that the multiple liquid outlet holes 344 are connected with the mixing chamber 421. Further, the liquid outlet portion 343 is cylindrical, and the multiple liquid outlet holes 344 are divided into multiple groups, and the multiple liquid outlet holes 344 in each group are evenly spaced along the vertical direction, and the multiple groups of liquid outlet holes 344 are evenly spaced along the circumference of the liquid outlet portion 343.

[0133] Please also see Figure 2 and Fig.12In some embodiments, a supporting protrusion 345 is provided on the outer periphery of the second flow guide 34, and the supporting protrusion 345 has a supporting surface. The electric device also includes a metal ring 91 and a metal ring 92. The metal ring 91 at least covers the supporting surface of the supporting protrusion 345, and the metal ring 92 is embedded in the bottom end of the brewing component 40. The metal ring 92 is supported on the metal ring 91 so that the brewing component 40 can be rotatably supported on the second flow guide 34.

[0134] Furthermore, the support protrusion 345 is disposed at one end of the liquid outlet 343 close to the guide portion 341, and the support surface is the upper surface of the support protrusion 345. The brewing component 40 is sleeved on the liquid outlet 343 and supported on the support protrusion 345. In actual application, when the brewing component 40 is sleeved on the liquid outlet 343, the metal ring 92 abuts against the metal ring 91.

[0135] It needs to be explained that, during operation, the brewing component 40 rotates in a preset direction, while the second flow guide 34 is fixed. In order to prevent the brewing component 40 and the second flow guide 34 from rotating relative to each other and causing wear, a metal ring 92 and a metal ring 91 are provided, and the surfaces of both are smoothed, and the metals fit together, which also seals the connecting cavity to a certain extent.

[0136] See also Figure 2 In some embodiments, the brewing component 40 includes a brewing piece 42, which is disposed at one end of the guide component 30 having the liquid outlet section, and the above-mentioned mixing chamber 421 and the liquid outlet communicated with the mixing chamber are both disposed at the brewing piece 42, and the above-mentioned metal ring 92 is also embedded at the bottom end of the brewing piece 42. Further, the brewing piece 42 is away from one end of the support seat 20.

[0137] In some embodiments, the brewing component 40 further includes a brewing cover 43 . The brewing component 42 has an open end. The brewing cover 43 is detachably connected to the open end of the brewing component 42 to close the mixing chamber 421 of the brewing component 42 .

[0138] That is to say, when adding materials is needed, the brewing cover 43 is opened, and the material to be brewed is poured into the mixing chamber 421. When brewing, it is necessary to ensure that the brewing cover 43 is connected to the brewing member 42. At the same time, the brewing cover 43 and the brewing member 42 are mutually clamped and fixed. If they are fixed by threaded connection, the brewing member 42 needs to be rotated during brewing, which may cause the threaded connection to loosen, which is prone to accidents.

[0139] In practical applications, the shape of the brewing cover 43 can be roughly the same as the cover body 60. Of course, the brewing cover 43 and the cover body 60 are both used to close the opening, and their general form is the same as that of a conventional cover. Other functional structures can be set accordingly, such as the matching groove 64 of the cover body 60, etc., and other details will not be elaborated.

[0140] In some embodiments, the brewing component 42 also has a connecting chamber and a liquid inlet for connecting the connecting chamber and the mixing chamber 421. The end of the guide component 30 away from the support component 20 extends into the connecting chamber, and the liquid outlet hole 344 is connected to the connecting chamber, so that the liquid outlet hole 344 is connected to the mixing chamber 421.

[0141] See also Fig.19 In some embodiments, the dispensing member 42 includes a cup-shaped portion 422 and a columnar portion 424. The columnar portion 424 is hollow, and the cup-shaped portion 422 is located on the periphery of the columnar portion 424. The columnar portion 424 encloses the above-mentioned connecting cavity, and the cup-shaped portion 422 and the columnar portion 424 enclose the above-mentioned mixing cavity 421.

[0142] Furthermore, the mixing chamber 421 is the inner cavity of the cup-shaped portion 422, and the opening communicating with the mixing chamber 421 is provided at the top end of the cup-shaped portion 422, the columnar portion 424 is coaxially arranged with the cup-shaped portion 422 and is located in the mixing chamber 421, and the columnar portion 424 is fixedly connected to the bottom of the cup-shaped portion 422.

[0143] In practical applications, the bottom end of the columnar portion 424 is also provided with an opening so that the end of the guide assembly 30 away from the support member 20 can extend into the connection cavity. It should be explained here that the bottom of the columnar portion 424 and the bottom of the cup-shaped portion 422 can be regarded as being composed of the same plate-like structure. In other words, the bottom of the columnar portion 424 can be regarded as a part of the bottom of the cup-shaped portion 422. Therefore, the bottom of the columnar portion 424 is provided with an opening, which means that the bottom of the cup-shaped portion 422 is provided with an opening, so that the connection cavity is connected to the outside through the opening.

[0144] Thus, the combined shape of the cup-shaped portion 422 and the columnar portion 424 can be regarded as two hollow cylindrical structures arranged coaxially, and the two cylindrical structures have at least one end flush with each other, and an annular plate is provided at the flush end to close the gap between the two cylindrical structures at that end.

[0145] In some embodiments, the transmission member 522 passes through the top of the columnar portion 424 and the brewing cover 43. Further, the top of the columnar portion 424 is provided with a polygonal hole matching the interface polygon of the third transmission part 5224, and the third transmission part 5224 extends from the polygonal hole and cooperates with the polygonal hole to drive the brewing member 42 and the brewing cover 43 to rotate.

[0146] The brewing cover 43 is provided with a through hole whose radial size is larger than the third transmission part 5224, that is, the brewing cover 43 rotates with the brewing member 42. Of course, in other embodiments, the brewing cover 43 may also be provided with a through hole matching the shape of the third transmission part 5224.

[0147] Specifically, the cylindrical liquid outlet portion 343 is located in the connecting cavity, and the transmission member 522, the liquid outlet portion 343 and the columnar portion 424 are all coaxially arranged, and the third transmission portion 5224 of the transmission member 522 extends in the vertical direction and passes through the liquid outlet portion 343 and the columnar portion 424 in sequence, and passes through the top of the columnar portion 424, and the hole opened at the upper end of the liquid outlet portion 343 for the third transmission portion 5224 to pass through is a circular hole, and the diameter of the circular hole is larger than the radial dimension of the third transmission portion 5224 to avoid the rotating third transmission portion 5224 from contacting and generating force therewith.

[0148] In some embodiments, the above-mentioned liquid inlet is provided on the columnar portion 424, and is specifically provided on the circumferential side wall of the columnar portion 424, and the liquid outlet is provided on the cup-shaped portion 422, and the liquid inlet is connected to the connecting cavity of the columnar portion 424, so that the liquid medium discharged from the liquid outlet enters the connecting cavity, and then enters the mixing cavity 421 from the liquid inlet connected to the connecting cavity.

[0149] What can be determined is that the liquid medium lifted by the lifting member 53 to the liquid outlet portion 343 has a certain flow rate, so it can be considered that the liquid medium is sprayed from the liquid outlet hole 344, part of the liquid medium is directly sprayed to the liquid inlet and enters the mixing chamber 421, and the remaining part is accumulated in the connecting chamber. The accumulated liquid medium can also rotate under the drive of the rotating brewing member 42, and when it rotates to a certain height, it will flow into the mixing chamber 421 from the liquid inlet.

[0150] See also Figure 5 In some embodiments, the brewing component 40 further includes a first filter element 44, which is disposed at the liquid outlet and is used to filter the substance to be brewed.

[0151] Among them, the first filter element 44 filters the substance to be brewed, which means that the substance to be brewed cannot pass through the first filter element 44, which can prevent the substance to be brewed from directly entering the accommodating cavity 142. When the substance to be brewed is dissolved in the liquid medium, it is mixed into a liquid solution, and the liquid solution can pass through the first filter element 44.

[0152] See also Figure 2 In some embodiments, the brewing component 40 further includes a second filter 46, which is disposed at the liquid inlet of the columnar portion 424 and is used to filter the substance to be brewed. The second filter 46 has the same function as the first filter 44, both of which can prevent the substance to be brewed from passing through. After the substance to be brewed is mixed with the liquid medium to form a liquid solution, the liquid solution can pass through the second filter 46, which also prevents the substance to be brewed from entering the connecting cavity from the liquid inlet.

[0153] It should be noted that the connecting chamber and the containing chamber 142 are different from the mixing chamber 421. The mixing chamber 421 rotates relatively to fully mix the liquid medium with the substance to be prepared. If the unmixed substance to be prepared enters the containing chamber 142 or the connecting chamber, the substance to be prepared may not be completely mixed with the liquid medium, affecting the taste of the drink.

[0154] At the same time, the substance to be brewed is usually a powdery or granular substance. When it enters the accommodating cavity 142 or the connecting cavity, taking the connecting cavity as an example, the substance to be brewed may accumulate on the metal ring 91, resulting in an increase in the friction between the metal ring 91 and the metal ring 92. Over time, it will cause greater wear on both.

[0155] Specifically, the first filter element 44 and the second filter element 46 are both filter screens, and the meshes of the filter screens can prevent the substance to be brewed from passing through.

[0156] In some embodiments, the liquid outlet is provided on a side of the dispensing member 42 away from the transmission member 522. Further, the liquid outlet is provided on the circumferential side wall of the cup-shaped portion 422. The liquid outlet can only be provided on the side wall or the bottom of the cup-shaped portion 422. If it is provided on the bottom, the liquid medium can flow out directly after entering, resulting in the inability to fully mix the liquid medium and the substance to be dispensed. Therefore, the liquid outlet is provided on the side wall of the cup-shaped portion 422.

[0157] In some embodiments, the number of the liquid inlet and the liquid outlet are both multiple, and the number of the corresponding first filter element 44 and the second filter element 46 is also multiple. Of course, in other embodiments, the number of the liquid inlet and the liquid outlet can also be multiple, and the number of the first filter element 44 and the second filter element 46 can both be one, the first filter element 44 wraps the side wall of the cup-shaped portion 422, and the second filter element 46 wraps the side wall of the columnar portion 424, so that the filtering effect can also be achieved.

[0158] In order to facilitate understanding of the technical solution of the present invention, the operation of the electric device in the above embodiment is described here:

[0159] Initially, the cover body 60 and the brewing cover 43 are removed, and a proper amount of water is first added to the accommodating chamber 142. The height of the water should be above the lifting member 53, and cannot be immersed in the mixing chamber 421. The water is adjusted according to the actual situation, and then a corresponding amount of the substance to be brewed is added to the mixing chamber 421. Next, the brewing cover 43 and the cover body 60 are sequentially closed. At this time, the control switch 56, the power supply and the driving member 51 are in a connected state.

[0160] In the working state, the switch button 564 is pressed, and the output shaft of the driving member 51 rotates in a preset direction, and drives the lifting member 53 and the brewing component 40 to rotate. The lifting member 53 rotates to transport the water in the accommodating chamber 142 to the liquid outlet 343, and sprays it out through the liquid outlet hole 344 of the liquid outlet 343. The sprayed water enters the mixing chamber 421 from the liquid inlet and mixes with the substance to be brewed in the mixing chamber 421. The rotating brewing component 40 not only ensures its mixing effect, but also throws the mixed solution out from the liquid outlet. The mixed solution returns to the accommodating chamber 142, and the solution returned to the accommodating chamber 142 will be lifted by the lifting member 53. In this way, a circulation state is entered, which can make the water and the substance to be brewed fully mixed to ensure the taste of the drink.

[0161] What needs to be explained in conjunction with the drawings as a whole is that in the above embodiments, some structures are fixed by screws 99. Since the fixing methods are the same and screws 99 are used, the only difference is that the models of screws 99 are different, so the same labels are used.

[0162] In addition, in combination with the above embodiments, it can be known that the above-mentioned electric device is a beverage brewing device, that is, a mixing device, but the closing of the cover body in the above embodiments drives the linkage member to move through the transmission member, and the structure that triggers the control switch to be electrically connected with the driving member during the movement can also be applied to stirring equipment or other electric equipment, as long as the electric equipment needs to operate in a closed shell to ensure safety, and is transmitted through a transmission shaft, so as to ensure that the electric equipment can only operate when the cover body is closed. This effect is controlled by the movement of the transmission shaft, and the specific structure can be designed according to the structure of the corresponding electric equipment.

[0163] Taking the stirring device as an example, the stirring device drives the tool to rotate through the transmission shaft. One end of the transmission shaft can be extended to the cover body, and the transmission shaft can be set to be movable. Then, a structure similar to a linkage part is set in the base body of the stirring device. The linkage part is also movable with the transmission shaft, and the linkage part can trigger the driving part of the stirring device to be electrically connected to the control switch of the stirring device during the movement, so that the driving part can be energized and run.

[0164] The movement of the transmission shaft may be achieved by a structure similar to that in the above-mentioned embodiment, that is, the two mating parts are movable in the vertical direction and meshed in the circumferential direction. Of course, other structures may also be used to achieve the movement of the transmission shaft.

[0165] Compared with the prior art, the electric device provided by the present invention has at least the following advantages:

[0166] 1) The lifting member transports the liquid medium immersed in the guide channel to the mixing chamber to mix with the substance to be brewed. The mixed liquid solution enters the accommodating chamber through the liquid outlet. The accommodating chamber and the guide channel are connected. The mixed liquid solution will also return to the brewing member from the lifting member, and circulate continuously, so that the substance to be brewed and the liquid medium are mixed more fully, which effectively improves the brewing effect, thereby improving the taste of the formed beverage, which is easy to be accepted by users and is conducive to promotion;

[0167] 2) When the cover is closed, the transmission part and the linkage part are pressed down, so that the linkage part is in the connected position, that is, the control switch and the driving part are connected. At this time, the user can control the driving part by operating the switch, which effectively avoids the possibility of accidents caused by not closing the cover and improves the safety performance of the electric equipment;

[0168] 3) The substance to be brewed is placed in the mixing chamber, and the first filter element and the second filter element prevent the substance to be brewed from entering the connecting chamber and the accommodating chamber, thereby avoiding the influence of the substance to be brewed on other components, and only the electric device needs to be disassembled for cleaning, which is more convenient and prolongs the service life of the device;

[0169] 4) The cooperation between the lifting member and the diverter member effectively improves the lifting effect, thereby improving the mixing effect of the substance to be prepared and the liquid medium, and further improving the taste of the beverage.

[0170] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0171] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
