Description

Technical Field

[0001] The present invention relates to the technical field of beverage brewing, and particularly to a beverage brewing device. Background Art

[0002] At present, after grinding coffee powder by a coffee machine, coffee liquid is obtained by brewing the coffee powder. For example, a funnel-type coffee machine is used to extract coffee liquid. Specifically, the funnel-type coffee machine brews the coffee powder in the coffee funnel through a brewing head, and then drips it into a coffee pot through a coffee liquid outlet below the coffee funnel. However, at present, all funnel-type coffee machines use direct-drop powder pressing, and direct-drop powder pressing is prone to the problem of uneven powder pressing, which affects the brewing effect and the taste of the coffee liquid. For example, Chinese Patent No. CN113842042A discloses a coffee powder presser, which includes a powder pressing body. The powder pressing body includes a handle part and a conical part. The lower part of the handle part is connected to the conical part and jointly defines a filling cavity inside the powder pressing body. Specifically, by holding the handle part by hand, the conical part presses the coffee powder. It can be seen that this coffee powder presser uses the method of directly hitting the coffee powder, and this powder pressing method will have the problem of uneven powder pressing with the inclination of the conical part. Summary of the Invention

[0003] In view of the above technical problems existing in the prior art, the present invention provides a beverage brewing device, which can rotate a powder pressing member to press towards a powdery food material, so that the powdery food material is evenly pressed, thereby ensuring the taste of the beverage obtained by brewing the powdery food material.

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] An embodiment of the present application provides a beverage brewing device. As Figures 1 to 5 shown, the beverage brewing device includes a funnel assembly 1, a brewing assembly 2, an actuating assembly, and a control assembly. The funnel assembly 1 includes a brewing chamber 101. The brewing assembly 2 is disposed above the brewing chamber 101. The brewing assembly 2 includes a rotary powder pressing member 201 and a brewing head 202 disposed on the rotary powder pressing member 201. The brewing head 202 communicates with the brewing chamber 101. The actuating assembly includes a first driving member 3 and a second driving member 4. The first driving member 3 is used to drive the rotary powder pressing member 201 to perform a lifting movement relatively close to or away from the brewing chamber 101, and the second driving member 4 is used to drive the rotary powder pressing member 201 to perform a rotating movement. The control assembly is at least electrically connected to the first driving member 3 and the second driving member 4. The control assembly is configured to control the working parameters of the first driving member 3 and the second driving member 4 to at least control the powder pressing movement of the rotary powder pressing member 201 pressing the powdery food materials in the brewing chamber 101, and to supply the brewing liquid to the brewing chamber 101 by the brewing head 202 when the powder pressing movement is in progress.

[0033] The powdery food materials in the above-mentioned brewing chamber 101 can be food materials such as coffee powder and bean powder. The beverage brewing device of the present application can brew various powdery food materials separately.

[0034] The above-mentioned brewing chamber 101 can be understood as a cavity with an open upper end, and the brewing assembly 2 is installed at the open upper end of the brewing chamber 101.

[0035] The above-mentioned brewing head 202 can be arranged at the lower end of the rotary powder pressing member 201, and the brewing head 202 is connected to the water supply assembly to provide brewing liquid for the brewing head 202 via the water supply assembly. Among them, the brewing head 202 can be detachably connected to the rotary powder pressing member 201, and the brewing head 202 moves up and down and rotates along with the rotary powder pressing member 201.

[0036] The above-mentioned water supply assembly can include a pump body, a heating member and a water tank. The heating member is used to heat the water discharged from the water tank, and the pump body is used to transport the water heated by the heating member to the brewing head 202. The pump body and the heating member can both be electrically connected to the control assembly to control the opening and closing of the pump body and the heating member via the control assembly.

[0037] The above-mentioned first driving member 3 and second driving member 4 can both be reduction motors, or other types of motors, and of course can also be energized driving devices capable of providing driving force. The present application does not limit the specific structures of the first driving member 3 and the second driving member 4, as long as they can drive the rotary powder pressing member 201 to move.

[0038] The above-mentioned first driving assembly can be drivingly connected to the rotary powder pressing member 201 through a transmission structure, so that the rotary powder pressing member 201 can perform lifting movement. The transmission structure can be one of the following structures or a combination of multiple structures: a lead screw nut structure, a worm and worm gear structure, a gear transmission structure, and a belt transmission structure.

[0039] The above-mentioned second driving assembly can be drivingly connected to the rotary powder pressing member 201 through another transmission structure, so that the rotary powder pressing member 201 can perform rotational movement. The another transmission structure can be one of the following structures or a combination of multiple structures: a lead screw nut structure, a worm and worm gear structure, a gear transmission structure, and a belt transmission structure.

[0040] A powder pressing plane can be arranged at the lower end of the above-mentioned rotary powder pressing member 201. The powder pressing plane can be in full contact with the powdery food materials in the brewing cavity 101 to rotate and press towards the powdery food materials. The rotational movement performed by the above-mentioned rotary powder pressing member 201 can be understood as a movement of rotating on the plane where the powder pressing plane is located.

[0041] The working parameters of the first driving member 3 and the second driving member 4 controlled by the above-mentioned control assembly can be understood as parameters capable of controlling the rotational speeds of the first driving member 3 and the second driving member 4. For example, the rotational speeds of the first driving member 3 and the second driving member 4 can be controlled by controlling parameters such as voltage and resistance.

[0042] The above control component can be built with electronic components such as timers, comparators, registers, digital logic circuits, etc., or implemented with processor chips such as single-chip microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), application-specific integrated circuits (ASICs), and their peripheral circuits.

[0043] The above brewing head 202 provides brewing liquid to the brewing chamber 101 during the powder pressing movement, thereby enabling the rotational powder pressing operation and the brewing operation of the beverage brewing device to be carried out simultaneously, so as to achieve the purpose of brewing a beverage with a better taste.

[0044] The rotating powder pressing member 201 of the present invention can be rotated and pressed against the powdery food materials under the combined drive of the first driving member 3 and the second driving member 4, so that the powdery food materials can be evenly pressed under the action of the rotating powder pressing member 201, ensuring the taste of the brewing liquid obtained by subsequently brewing the powdery food materials, and can enter the brewing liquid for brewing when rotating and pressing against the powdery food materials, realizing the combination of rotating powder pressing and brewing the powdery food materials, which can not only ensure the taste of the brewed beverage, but also ensure the convenience of use.

[0045] In some embodiments, the control component is specifically configured to control the rotational speed relationship between the first driving member 3 and the second driving member 4, so as to control the rotating powder pressing member 201 to perform one of the following movements: a descending movement, a powder pressing movement, and an ascending movement.

[0046] In this way, by controlling the rotational speeds of the first driving member 3 and the second driving member 4, the rotating powder pressing member 201 can perform different movements, namely one of the descending movement, the powder pressing movement, and the ascending movement, so as to be able to descend for rotating powder pressing and ascend away from the brewing chamber 101 after the rotating powder pressing is completed.

[0047] When the above rotating powder pressing member 201 performs a descending movement under the combined drive of the first driving member 3 and the second driving member 4, the descending movement at least includes a linear movement in the direction of approaching the brewing chamber 101. In addition, the rotating powder pressing member 201 can also perform a rotational movement during the descending movement, that is, the rotating powder pressing member 201 descends while rotating.

[0048] When the above rotating powder pressing member 201 performs a powder pressing movement under the combined drive of the first driving member 3 and the second driving member 4, the powder pressing movement at least includes a rotational movement in which the rotating powder pressing member 201 rotates and presses against the powdery food materials. At this time, the rotating powder pressing member 201 does not perform an ascending movement and a descending movement, that is, the rotating powder pressing member 201 maintains a rotational movement at this height position. The action of the above brewing head 202 providing brewing liquid to the brewing chamber 101 is carried out synchronously with the powder pressing movement.

[0049] When the above-mentioned rotary powder pressing member 201 moves upward under the combined drive of the first driving member 3 and the second driving member 4, this upward movement at least includes a linear movement in a direction away from the brewing chamber 101. In addition, the rotary powder pressing member 201 can also perform a rotational movement during the upward movement, that is, the rotary powder pressing member 201 rises while rotating.

[0050] During the working process of the beverage brewing device, the downward movement, powder pressing movement, and upward movement performed by the above-mentioned rotary powder pressing member 201 can be understood as occurring in sequence. That is, the rotary powder pressing member 201 first descends close to the brewing chamber 101, can rotate to press the powder after descending to the second position, and after the powder pressing movement is completed, the rotary powder pressing member 201 then rises to the first position to be away from the brewing chamber 101 to prepare for the next brewing. Specifically, it can be combined with Figure 3 and Figure 5 , Figure 3 in which the rotary powder pressing member 201 shown is in the first position, Figure 5 in which the rotary powder pressing member 201 shown is in the second position.

[0051] In some embodiments, the control component is specifically configured to: control the rotation speed of the first driving member 3 to be greater than the rotation speed of the second driving member 4, so that the rotary powder pressing member 201 moves downward at least in a direction close to the brewing chamber 101; control the rotation speed of the first driving member 3 to be equal to the rotation speed of the second driving member 4, so that the rotary powder pressing member 201 performs a powder pressing movement in the brewing chamber 101; and control the rotation speed of the first driving member 3 to be less than the rotation speed of the second driving member 4, so that the rotary powder pressing member 201 moves upward at least in a direction away from the brewing chamber 101.

[0052] In this way, by making the rotation speed of the first driving member 3 greater than, equal to, or less than the rotation speed of the second driving member 4, one of the downward movement, powder pressing movement, and upward movement of the rotary powder pressing member 201 can be realized. The above-mentioned method of controlling the movement of the rotary powder pressing member 201 is simple and can achieve precise control of the movement of the rotary powder pressing member 201.

[0053] When the rotation speed of the first driving member 3 is greater than the rotation speed of the second driving member 4, the fact that the above-mentioned rotary powder pressing member 201 at least makes a downward movement can be understood as that the rotary powder pressing member 201 can perform a rotational movement while making a downward movement.

[0054] When the rotation speed of the first driving member 3 is less than the rotation speed of the second driving member 4, the fact that the above-mentioned rotary powder pressing member 201 at least makes an upward movement can be understood as that the rotary powder pressing member 201 can perform a rotational movement while making an upward movement.

[0055] In some embodiments, such as Figures 2 to 4 and Figure 6As shown, the brewing assembly 2 further includes a filter member 203 provided at the lower end of the rotary powder pressing member 201. The filter member 203 is located below the brewing head 202, and a convex portion 204 is provided on the side of the filter member 203 facing the brewing chamber 101. The convex portion 204 is used to press against the powdery ingredients in the brewing chamber 101 under the drive of the rotary powder pressing member 201.

[0056] In this way, the brewing liquid discharged from the brewing head 202 can be filtered by the filter member 203 and then enter the brewing chamber 101 to brew the powdery ingredients. Moreover, the rotating convex portion 204 can make the powdery ingredients in the brewing chamber 101 be evenly pressed, so as to achieve the purpose of preparing a drink with a better taste.

[0057] The above-mentioned convex portion 204 can be configured as a long strip shape and can be arranged in the middle of the filter member 203 to press more evenly against the powdery ingredients.

[0058] The above-mentioned filter member 203 can be configured as a plate shape, and the convex portion 204 is formed on the lower plate surface of the filter member 203 to contact the powdery ingredients more. The above-mentioned powder pressing plane can be configured as the lower plate surface of the filter member 203.

[0059] Moreover, a gap can be formed between the outer edge of the filter member 203 and the inner wall of the brewing chamber 101 to ensure that while the filter member 203 rotates stably, it can better press against the powdery ingredients and prevent the problem of unstable rotation of the filter member 203 caused by interference between the filter member 203 and the inner wall of the brewing chamber 101.

[0060] A first sealing ring 12 can be provided between the above-mentioned brewing head 202 and the filter member 203 to achieve the sealed connection between the brewing head 202 and the filter member 203, so that the brewing liquid can enter the brewing chamber 101 after being filtered by the filter member 203.

[0061] In some embodiments, as Figures 2 to 5 and Figure 7 shown, the actuating assembly further includes an inner transmission shaft 5 connected to the output end of the first driving member 3. The rotary powder pressing member 201 is sleeved outside the inner transmission shaft 5 and moves up and down along the axial direction of the inner transmission shaft 5 under the drive of the inner transmission shaft 5.

[0062] In this way, through the sleeved relationship between the inner transmission shaft 5 and the rotary powder pressing member 201, the inner transmission shaft 5 can stably drive the rotary powder pressing member 201 to move up and down.

[0063] As Figure 7As shown, the inner transmission shaft 5 described above may have a connected tooth portion 501 and a transmission external thread 502. The tooth portion 501 is used to interact with the output end of the first driving member 3, so as to drive the transmission external thread 502 to rotate through the tooth portion 501. A transmission internal thread may be formed on the inner wall of the rotary powder pressing member 201, and the transmission external thread 502 is threadedly connected to the transmission internal thread of the rotary powder pressing member 201, so that the rotary powder pressing member 201 can perform a lifting movement driven by the rotation of the transmission external thread 502.

[0064] A driving wheel may be installed on the output end of the first driving member 3 described above, and the driving wheel meshes with the tooth portion 501 of the inner transmission shaft 5 to drive the inner transmission shaft 5 to rotate.

[0065] In some embodiments, as Figures 2 to 5 shown, the actuating assembly further includes a gear set 6 connected to the output end of the second driving member 4. The gear set 6 is sleeved on the lower end of the rotary powder pressing member 201 and drives the rotary powder pressing member 201 to perform a rotational movement.

[0066] In this way, through the gear set 6 connected to the output end of the second driving member 4, it can be realized that the second driving member 4 can stably drive the rotary powder pressing member 201 to perform a rotational movement, improving the structural stability.

[0067] As Figures 1 to 3 shown, the above-mentioned beverage brewing device further includes a mounting bracket 15. The first driving member 3 can be installed on the upper part of the mounting bracket 15, and the second driving member 4 can be installed on the lower part of the mounting bracket 15. The mounting bracket 15 may have a mounting cavity. The rotary powder pressing member 201 is installed in the mounting cavity of the mounting bracket 15 and performs a lifting movement and a rotational movement in the mounting cavity.

[0068] The above-mentioned gear set 6 can be installed on the mounting bracket 15 to stably drive the rotary powder pressing member 201 in the mounting cavity to move.

[0069] In some embodiments, as Figures 2 to 5 and Figure 8 shown, the gear set 6 includes a rotating wheel 601 and a transmission wheel 602 that mesh with each other. The transmission wheel 602 is connected to the output end of the second driving member 4. The rotating wheel 601 is sleeved on the lower end of the rotary powder pressing member 201, and a positioning block 603 is provided on the inner wall of the rotating wheel 601, and a sliding groove 205 adapted to the positioning block 603 is provided on the outer wall of the rotary powder pressing member 201.

[0070] In this way, the rotary powder pressing member 201 can be stably driven to perform a rotational movement through the meshing rotating wheel 601 and transmission wheel 602, and through the positioning block 603 on the rotating wheel 601 and the sliding groove 205 on the rotary powder pressing member 201, the rotary powder pressing member 201 can rotate synchronously and stably with the rotating wheel 601.

[0071] The above-mentioned positioning blocks 603 can be multiple. The multiple positioning blocks 603 are arranged around the rotating powder pressing member 201, and the positioning blocks 603 are arranged in one-to-one correspondence with the sliding grooves 205 to cooperate with the rotating powder pressing member 201, so that the rotating powder pressing member 201 rotates stably along with the rotating wheel 601. Preferably, the multiple positioning blocks 603 can be evenly arranged to improve the structural stability.

[0072] In some embodiments, such as Figures 2 to 5 and Figure 9 As shown, the beverage brewing device further includes a first position detection device 7 and a second position detection device 8. A trigger portion 206 is provided on the outer wall of the rotating powder pressing member 201. The trigger portion 206 is used to trigger the first position detection device 7 when rising to the first position and trigger the second position detection device 8 when descending to the second position.

[0073] In this way, the lifting position of the rotating powder pressing member 201 can be accurately detected by the first position detection device 7 and the second position detection device 8. Moreover, when the rotating powder pressing member 201 descends to the second position, the brewing head 202 can be timely controlled to supply the brewing liquid to the brewing chamber 101.

[0074] The above-mentioned first position detection device 7 and second position detection device 8 can both be electrically connected to the control component. After the powdery ingredients enter the brewing chamber 101, the control component can first control the rotation speed of the first driving member 3 to be greater than that of the second driving member 4, so that the rotating powder pressing member 201 moves downward until the control component receives the in-place signal generated by the second position detection device 8. After the control component receives the in-place signal generated by the second position detection device 8, the control component will control the rotation speed of the first driving member 3 to be equal to that of the second driving member 4, so that the rotating powder pressing member 201 performs a powder pressing movement. After brewing is completed, the control component controls the rotation speed of the first driving member 3 to be less than that of the second driving member 4, so that the rotating powder pressing member 201 moves upward until the control component receives the in-place signal generated by the first position detection device 7, and then the control component will control the first driving member 3 and the second driving member 4 to stop working to prepare for the next brewing.

[0075] The above-mentioned beverage brewing device further includes a first switch bracket 11 for mounting the first position detection device 7 and the second position detection device 8 to stably install the first position detection device 7 and the second position detection device 8.

[0076] In some embodiments, such as Figures 1 to 5 As shown, the beverage brewing device further includes a powder feeding component 9 connected to the funnel component 1. The powder feeding component 9 has a powder feeding channel 901 and an air inlet channel 902 that are respectively communicated with the brewing chamber 101. The air inlet channel 902 is at least communicated to the bottom of the powder feeding channel 901 to blow the powdery ingredients in the powder feeding channel 901 into the brewing chamber 101.

[0077] In this way, after the powdered food ingredients are transported to the brewing chamber 101 through the powder inlet passage 901, the gas in the air inlet passage 902 can blow the residual powdered food ingredients in the powder inlet passage 901 clean, so as to avoid the problem of long-term residue of the powdered food ingredients in the powder inlet passage 901, which may cause food spoilage and affect food safety.

[0078] The above-mentioned beverage brewing device may further include a coffee grinder. After the beverage brewing device is started, the coffee grinder performs a grinding operation to prepare powdered food ingredients. Then, the powdered food ingredients enter the brewing chamber 101 through the powder inlet passage 901.

[0079] The gas in the above-mentioned air inlet passage 902 can be blown to the bottom of the powder inlet passage 901 after the powdered food ingredients in the powder inlet passage 901 are fed. Specifically, an air pump may be connected to the air inlet passage 902 to supply gas to the air inlet passage 902 through the air pump.

[0080] In some embodiments, as Figures 2 to 5 shown, the funnel assembly 1 further includes a funnel support 102 and a funnel body 103 connected to the lower part of the funnel support 102. The funnel support 102 and the funnel body 103 cooperate to form the brewing chamber 101. The funnel body 103 is used to support the powdered food ingredients. The beverage brewing device further includes a third position detection device 10 for detecting the position of the funnel body 103. The third position detection device 10 is electrically connected to the control component, and the control component is further configured to control the first driving member 3 and the second driving member 4 to work after receiving the in-place signal of the funnel body 103 sent by the third position detection device 10.

[0081] In this way, the third position detection device 10 can accurately detect whether the funnel body 103 is installed in place. After detecting that the funnel body 103 is installed in place, the beverage brewing device then performs subsequent brewing operations.

[0082] The above-mentioned funnel support 102 may be assembled by a plurality of supports. For example, the funnel support 102 includes an upper support and a lower support connected to each other. The funnel body 103 is connected to the lower support, and the upper support is connected to the mounting support 15.

[0083] The above-mentioned beverage brewing device further includes a second switch bracket 13 for installing the third position detection device 10. The second switch bracket 13 can be installed on the funnel bracket 102. An elastic member 131 and a push rod 132 can also be installed on the second switch bracket 13. After the funnel body 103 is placed in place, the push rod 132 will be triggered, and the third position detection device 10 will be triggered through the push rod 132, so that the control component can receive the in-place signal sent by the third position detection device 10. After the funnel body 103 is removed from the funnel bracket 102, the elastic member 131 can reset the push rod 132, so that the push rod 132 is away from the third position detection device 10, and the control component can receive the removal signal that the funnel body 103 is not in place sent by the third position detection device 10.

[0084] The above-mentioned funnel body 103 can be hermetically connected to the funnel bracket 102 through a second sealing ring 14 to ensure the tightness of the installation and avoid liquid leakage problems.

[0085] The working principle of the beverage brewing device is described below: Place the funnel body 103 at the lower part of the funnel bracket 102. The in-place funnel body 103 will trigger the push rod 132, and the third position detection device 10 will be triggered through the push rod 132, so that the control component can receive the in-place signal sent by the third position detection device 10. After receiving the in-place signal, the control component will start the bean grinder to grind the beans to prepare the powdered ingredients, and make the powdered ingredients enter the brewing chamber 101 through the powder inlet channel 901. After the powdered ingredients are transported to the brewing chamber 101 through the powder inlet channel 901, the powdered ingredients remaining in the powder inlet channel 901 can be blown into the brewing chamber 101 by the gas in the air inlet channel 902.

[0086] Then, the control component can control the rotation speed of the first driving member 3 to be greater than the rotation speed of the second driving member 4, so that the rotary powder pressing member 201 moves downward until the control component receives the in-place signal generated by the second position detection device 8. After the control component receives the in-place signal generated by the second position detection device 8, the control component will control the rotation speed of the first driving member 3 to be equal to the rotation speed of the second driving member 4, so that the rotary powder pressing member 201 performs a powder pressing movement. During the powder pressing movement, the control component can control the water supply component to make the brewing head 202 supply the brewing liquid to the brewing chamber 101 for brewing while pressing the powder. After the brewing is completed, the control component controls the rotation speed of the first driving member 3 to be less than the rotation speed of the second driving member 4, so that the rotary powder pressing member 201 moves upward until the control component receives the in-place signal generated by the first position detection device 7, and then the control component will control the first driving member 3 and the second driving member 4 to stop working to prepare for the next brewing.

[0087] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
