Description

Technical Field

[0001] A beverage brewing device and a fluid texturing apparatus for use therewith are provided. Background Art

[0002] Various systems and methods for brewing beverages, such as coffee or tea, are known. These systems typically include drip brewing systems, in which hot water is passed through coffee grounds and brewed into a carafe, or French press systems, in which coffee grounds and water are mixed in a container and a water-permeable plunger is pressed into the container from above to collect ground coffee at the bottom of the container. Existing beverage brewing systems are typically designed to receive only a single form of flavorant (e.g., loose coffee grounds), or alternatively, pre-packaged coffee grounds capsules or cartridges.

[0003] Many coffee and espresso based beverages include a heated and textured milk or milk-like substitute. Equipment that includes a steam injection device (which serves as a heat source) and a rotating stirrer (which helps distribute the steam and air in the milk or milk-like substitute) is called a fluid texturizing device. In order to use the steam source to achieve the proper consistency, the user must be trained to add the appropriate amount of steam to the milk and stir the milk. Home-use equipment or stand-alone equipment for texturizing fluids is intended to provide a simpler operation with similar texturizing results. However, many of these devices are not sufficient to produce a properly textured product. Existing integrated fluid texturizing equipment or stand-alone fluid texturizing equipment have only a single milk foam type in all settings due to their limited capabilities. Summary of the invention

[0004] A beverage brewing device and a fluid texturizing apparatus for use therewith are provided.

[0005] In one aspect, a fluid texturizing device is provided. In one embodiment, the fluid texturizing device may include a housing shell extending between a first end and a second end.

[0052] It should be noted that the drawings are not necessarily drawn to scale. The drawings are intended to depict only typical aspects of the subject matter disclosed herein, and therefore should not be considered to limit the scope of the disclosure. DETAILED DESCRIPTION

[0053] Certain exemplary embodiments will now be described to provide an overall understanding of the principles of structure, function, manufacture and use of the apparatus and methods disclosed herein. One or more examples of these embodiments are shown in the accompanying drawings. It will be appreciated by those skilled in the art that the apparatus and methods specifically described herein and shown in the accompanying drawings are non-limiting exemplary embodiments, and that the scope of the invention is limited only by the claims. Features shown or described in conjunction with an exemplary embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be included within the scope of the invention.

[0054] Generally speaking, when steam is injected into milk, water is added to the milk to a certain extent, which in turn dilutes the milk. If the steam pressure is low, the time required to heat the milk will be longer, resulting in more water being injected. Therefore, the steam injection speed will be slower, resulting in larger bubble size, which corresponds to a poor milk texture. Instead of texturized milk, the result is hot milk with some aerated foam on top, which greatly affects the taste of milk-based drinks because the milk does not blend with the espresso in this state. In addition, in the case of low steam pressure, it may occur that the milk is not heated enough. Alternatively, if the steam pressure is too high, the time required to heat the milk will be shorter. Therefore, the steam injection speed will be faster, resulting in smaller bubble size, which corresponds to the desired high-quality milk texture. However, using high-pressure steam may result in overheating of the milk, which may result in an undesirable texture.

[0055] Therefore, a device for texturizing a fluid (e.g., milk) is provided. In an exemplary embodiment, a fluid texturizing device generates different air and steam incorporation rates in a container by changing the stirring speed and stirring direction during the texturizing process to solve the aforementioned problems. By changing the incorporation rate, the fusion of steam and air in the fluid in the container can be changed while controlling the stirring speed separately. When rotating in a first rotational direction, the air path is opened, allowing a mixture of both air and steam to be fused into the fluid. When rotating in a second rotational direction, the air path is closed, allowing only steam to be fused into the fluid. In one aspect, after a specific period of time, the agitator can change the direction of rotation to incorporate a certain amount of steam and air into the fluid. By changing the stirring speed and / or stirring direction between different stages, the steam injection rate can be very high while preventing the milk from overheating. In addition, a temperature sensor can be provided in the body of the texturizing device to accurately measure the temperature of the fluid in the container to avoid insufficient or overheating of the fluid, thereby achieving the desired result programmed by the user.

[0056] Figures 1 to 3 An embodiment of a beverage brewing device 10 is shown, which is operable to prepare a brewed beverage and is suitable for use on a support surface such as a countertop. It will be appreciated by those skilled in the art that the fluid texturizing apparatus disclosed herein can be used with any beverage brewing apparatus, and the apparatus shown is provided only as an example of an apparatus for use with a fluid texturizing apparatus. As shown, the beverage brewing device 10 generally includes a housing 24 having a base 26. The bottom surface 27 of the base 26 can be configured to be positioned on a support surface such as a countertop. The upper surface of the base 26 can define an area for positioning a container that is configured to receive a brewed beverage output from the beverage brewing device 10.

[0057] The beverage brewing system may further include a reservoir 32 disposed on the housing 24 and configured to store a desired amount of fluid (e.g., water) therein for brewing a beverage, including but not limited to coffee or tea. The reservoir 32 may be detachably connected to the housing 24 for easy filling. The housing 24 may further include a brewing chamber 34, in which edible flavors such as coffee powder or tea leaves may be placed.

[0058] The fluid delivery system 44 is disposed within the housing 24 and is configured to transfer fluid from the reservoir 32 to the brewing chamber 34. The fluid delivery system 44 may include at least one fluid supply line 33 or fluid supply conduit extending between the outlet end of the reservoir 32 to the inlet of the brewing chamber 34. The fluid delivery system 44 may also include a heater 48 that is operable to heat water supplied from the reservoir 32 to a desired temperature before delivering it to the brewing chamber 34. In addition, the fluid delivery system 44 may include a pumping mechanism 50 that is operable to provide a positive pumping action to push or draw fluid (e.g., water) from the reservoir 32 through the at least one fluid supply line 33 and the heater, thereby delivering the fluid to the brewing chamber 34.

[0059] like Figure 1 As further shown, the beverage brewing device 10 may include a user interface 54 for receiving one or more inputs from a user. The user interface 54 is formed at a portion of the housing 24, for example, at the front surface adjacent to the brewing chamber 34. Although the user interface 54 is shown as being on the front surface of the housing 24, the user interface 54 may be located at any position on the housing, and the position may vary depending on the configuration of the beverage brewing device 10. The user interface 54 may include one or more buttons, knobs, or other control input devices 56. Alternatively or additionally, the user interface 54 may include a touch screen, or the user interface may be configured to receive inputs from smart devices such as mobile phones or tablet computers via an "app" or other suitable connection. The operation of the user interface will be described in detail below.

[0060] The operation of the beverage brewing apparatus 10 may be controlled by a controller 58 that is operably coupled to components of the beverage brewing apparatus 10 and configured to receive one or more input signals from the user interface 54. The controller 58 may include one or more of the following: a microprocessor; a microcontroller; an application specific integrated circuit (ASIC); or any other form of electronic controller known in the art.

[0061] Those skilled in the art will appreciate that the beverage brewing device can have a variety of other configurations and can include various features, and the beverage brewing device shown is only one exemplary embodiment. Other exemplary embodiments of the beverage brewing device are disclosed in US Pat. No. 11,246,446, which is incorporated herein by reference in its entirety.

[0062] In addition to having the necessary components for producing a brewed beverage, the beverage brewing device 10 may also have a mounting arm 90 that is movably coupled to the housing 24 for mounting the fluid texturizing device 100 to the housing. In the illustrated embodiment, the mounting arm 90 is positioned on one side of the housing, however, the mounting arm 90 may be positioned at various other locations.

[0063] like Figures 4 to 6 , the mounting arm 90 can have a generally elongated configuration having a first end 90a and a second end 90b. The first end 90a can be pivotally secured to a frame 91 at a pivot joint 92. The frame 91 can be disposed within the housing 24, and the frame can be configured to allow the mounting arm 90 to pivot between a storage position and an operating position. In the storage position, the mounting arm 90 pivots to be flush with and / or against the housing 24, and in the operating position, the mounting arm 90 extends from the housing at a continuously vertical angle to allow a container to be disposed below the fluid texturizing device 100, which is connected to the mounting arm 90.

[0064] The second end 90b of the mounting arm 90 may include a mating surface 93 defining a connection feature. The connection feature may have various input ports and output ports for transferring materials and signals into and out of the fluid texturing device 100. The mating surface 93 is configured to face downward and perpendicular to the support surface so that the fluid texturing device 100 extends in a vertical direction when connected to the mounting arm 90. The various input ports and output ports on the mating surface 93 of the mounting arm 90 may include a steam injection port 94, a drive shaft port 95, and an electrical terminal 80. As shown in FIG. Figure 6 As shown, the drive shaft port 95 can be disposed in the center of the mating face 93, and the steam injection port 94 and the electrical terminal 80 can be radially spaced from the drive shaft port 95. In addition, the mating face 93 can include features configured to selectively engage the fluid texturing device 100 to retain the fluid texturing device 100 on the mounting arm 90.

[0065] Fig. 7A, the steam injection port 94 is shown in more detail in the figure, and the steam injection port includes a tube 94a located within and extending through the mounting arm 90. The tube 94a extends out of the mating surface 93 and extends vertically downward, and has an outlet 94b at the end of the tube 94a. When the steam leaves the outlet 94b, the steam will enter the steam injection pipe of the fluid texturizing device 100, which will be explained in more detail below. The outlet 94b may include a seal 94c disposed on the outer surface of the outlet 94b, which helps to seal the outlet 94b with the steam injection pipe of the fluid texturizing device 100. In some aspects, the seal 94c can be formed of a deformable silicon material, but other types of seals are also considered to be within the scope of the present disclosure.

[0066] To generate steam at the fluid chemistry apparatus 100, the tube 94a may be configured to be coupled to a steam source 60 disposed within the housing 24, such as Figure 3 As shown. The steam source 60 can be integrated with the heater 48, or the steam source can be a separate unit, and the steam source can be configured to generate steam and deliver the steam to the outlet 94b through the tube 94a. The steam source 60 can communicate with the controller 58, which controls the amount and temperature of the steam generated by the steam source 60. In some aspects, the steam generated by the steam source 60 can be dry steam generated by heating the water contained in the reservoir 32. A pump can be used to move the steam from the steam source 60 to the steam injection port 94, or the pressure of the steam itself can be sufficient to move the steam from the steam source 62 to the steam injection port 94.

[0067] As noted above, a drive shaft port 95 is also provided on the mating surface 93 and is configured to transmit rotational motion to the fluid texturing device 100. Figure 7BAs shown, the drive shaft port 95 includes a hollow body 95a that extends outward from the mating face 93 and has a hole 95b disposed therein. A drive feature 95c is disposed within the hollow body 95a and, as will be explained in more detail below, is configured to drive the rotational movement of the drive shaft of the fluid texturing device 100 when the fluid texturing device 100 is connected to the mounting arm 90. In the illustrated embodiment, the drive feature 95c is in the form of a plurality of tabs (e.g., four tabs) that abut against corresponding tabs on the drive shaft of the fluid texturing device 100. The tab 95d may protrude radially outward from the central axis 95e of the drive feature 95c and may be oriented in a vertical direction along the inner surface of the hollow body 95a of the drive shaft port so that the drive shaft of the fluid texturing device 100 may be removed and replaced in a vertical direction relative to the mounting arm 90 while still allowing the rotational movement to be transmitted from the drive feature 95c to the drive shaft of the fluid texturing device 100. Although four tabs are shown, more or fewer tabs are sufficient and are considered within the scope of the present disclosure. The hollow body 95a can be connected to a drive shaft of a motor 64 disposed in the second end 90b of the mounting arm 90 so that the motor 64 can rotate the hollow body 95a. The motor 64 can be connected to a controller 58 that controls the rotational speed of the motor 64. In certain embodiments, the motor 64 can be a direct current (DC) variable speed motor, wherein the controller 58 controls the output speed according to the desired fluid texture, as explained in more detail below.

[0068] like Figures 5 to 7B As further shown, the electrical terminal 80 can be disposed on a side of the drive shaft port 95 opposite the steam injection port 94. The electrical terminal 80 shown includes pogo pins 80a, 80b that are configured to contact corresponding electrical contacts on the fluid texturing device 100, which will be explained in more detail below. The pogo pins 80a, 80b extend downward from the mating surface 93 and can be vertically retracted into the mating surface 93 when contacting corresponding electrical contacts on the fluid texturing device 100. The pogo pins 80a, 80b are connected to the controller 58 and can be configured to send signals to the controller 58 based on various operating conditions of the fluid texturing device 100, such as the temperature of the fluid surrounding the fluid texturing device 100, the speed of the agitator, or the connection status of the fluid texturing device 100. Although the electrical terminal 80 is shown as having multiple pogo pins, any type of electrical connector is sufficient and is considered to be within the scope of the present disclosure.

[0069] As noted above, the mounting arm 90 may also include a mating feature configured to removably engage the fluid texturing device to keep the device on the brewing device. In the illustrated embodiment, the mating feature is in the form of tabs 99a, 99b, which protrude outward from the mating surface 93 and are configured to engage with corresponding connection features in the fluid texturing device 100, which will be explained in more detail below. The tabs 99a, 99b shown extend through the slots 97a, 97b on the mating surface and can be deflected to allow the tabs 99a, 99b to move radially inward and radially outward. Buttons 98a, 98b may be disposed on the outer surface of the second end 90b of the mounting arm 90 and may be integrated with or connected to the tabs 99a, 99b. Buttons 98a, 98b may be elastically biased outwardly so that the tabs 99a, 99b are also radially biased outwardly, thereby keeping the fluid texturing device on the brewing device. During the attachment of the fluid texturing device to the mounting arm, the device can cause the tabs 99a, 99b to deflect radially inward, and once fully connected, the tabs will return to the radially outward position. In addition, a force can be applied to the buttons 98a, 98b to move the buttons radially inward to move the tabs 99a, 99b radially inward, thereby releasing the fluid texturing device 100 from the mating surface 93.

[0070] As stated above, the fluid texturizing device 100 is configured to be detachably disposed on the mounting arm 90 . Figures 8 to 10B , an exemplary embodiment of a fluid texturizing apparatus 100 is shown in FIG. As shown, the fluid texturizing apparatus 100 generally includes a hollow, elongated housing 102 having a steam injection tube 118 and a drive shaft 116 extending therethrough. The drive shaft 116 can be coupled to the drive feature 95c via a coupling 117. For example, the tab 95d can be received within the coupling 117 at a first end of the coupling 117. The drive shaft 116 can be attached to the coupling 117 at a second end opposite the first end. The steam injection tube 118 is configured to deliver steam to the fluid, and the drive shaft 116 includes an agitator 140 at its end for mixing the fluid.

[0071] The housing 102 can have a variety of configurations, but in the illustrated embodiment, the hollow, elongated housing has a first end 102a and a second end 102b. The first end 102a can have a mating portion that allows multiple inputs and outputs of the fluid texturizing device to communicate with components within the beverage brewing apparatus 10, and the second end 102b can interact with the fluid. In the illustrated embodiment, the first end 102a is generally circular, while the second end 102b has an elliptical cross-section, and the portion of the housing 102 extending between the first end 102a and the second end 102b has an elliptical cross-section.

[0072] The mating portion of the housing 102 may include various features for mating with connection features on the mounting arm of the beverage dispensing device. In particular, similar to the mating surface 93, the housing 102 may have a mating surface 106 that includes a steam injection port 110, a drive shaft port 112, an electrical terminal 86, and mating grooves 114a, 114b, each of which will be discussed in more detail below. The mating surface 106 may also include mating grooves 114a, 114b that are disposed on opposite sides of the drive shaft port 112 and are configured to accommodate corresponding tabs 99a, 99b on the mounting arm.

[0073] The steam injection port 110 is configured to cooperate with the steam injection port 94 fluid on the mounting arm so that steam is transmitted from the steam source 60 in the housing 24 through the steam injection tube 118, which extends from the first end 102a of the housing to the second end 102b of the housing. The steam injection tube 118 can be a round tube with an inner cavity that allows steam to flow from the steam injection port 110 to an outlet 122 disposed in the end 120. In some aspects, the steam injection tube 118 or its inner cavity can taper from the first end 102a to the second end 102b. The tapering configuration can help reduce the back pressure of steam as it travels along the steam injection tube 118. The end 120 can be positioned near the second end 102b of the housing 102 for injecting steam into the fluid. In one embodiment, the end 120 can be formed by a separate component screwed on the steam injection tube 118. However, in other aspects, the end can be integrated with the tube 118. Those skilled in the art will appreciate that the steam injection tube may be in the form of a lumen extending through the housing and formed integrally with the housing, rather than necessarily being in the form of a separate tube extending through the housing.

[0074] As will be discussed in more detail below, the position of the steam injection tube 118 and the tip 120 can be varied to control the effect on the fluid. In one embodiment, the steam injection tube 118 is spaced a distance from the drive shaft 116 to position the tip 120 and the outlet 122 a distance from the agitator. Fig.13As shown, the distance D between the end 120 and the drive shaft 116 is 14.46 millimeters (mm). In addition, in some embodiments, the end 120 can be spaced apart from the drive shaft 116 extending along the centerline CL at different distances in the range of about 5.00 mm to 32.00 mm. In one aspect, the distance D between the end 120 and the drive shaft 116 is 6.00 mm, so that the end 120 is configured to inject steam into the innermost portion of the agitator 140. On the other hand, the distance D between the end 120 and the drive shaft 116 is 14.46 mm, so that the end 120 is configured to radially spray steam between the outermost portion of the agitator 140 and the innermost portion of the agitator cover 143. On the other hand, the distance D between the end 120 and the drive shaft 116 is 30.00 mm, so that the end 120 is configured to radially spray steam outside the outermost portion of the agitator cover 143. Additionally, the end 120 of the tube 118 may be configured to be positioned vertically above the agitator 140 to better incorporate air and steam into the fluid being agitated by the agitator 140, as will also be explained in greater detail below.

[0075] like Figure 8 and Fig. 9 As further shown, the mating surface 106 may also include an electrical terminal 86 disposed thereon, which is positioned on a side of the drive shaft port 112 opposite the steam injection port 110. Similar to the electrical terminal 80 on the mating surface 93, the electrical terminal 86 on the mating surface 106 of the fluid texturizing device 100 may include spring pins 86a, 86b, which correspond to the spring pins 80a, 80b. When the fluid texturizing device 100 is connected to the mounting arm 90, the spring pins 80a, 80b contact the spring pins 86a, 86a, so that a signal from the temperature sensor 130 can be sent to the controller 58 within the housing 24 of the beverage brewing device 10. As shown in FIG. Fig. 10A As shown, the tube 126 can extend from the electrical terminal to the second end 102b of the housing 102. It will be appreciated by those skilled in the art that the tube can be in the form of a lumen formed integrally with the housing, and that the tube need not be a separate component. The tube 126 can be configured to carry a wire 128 passing therethrough, which is used to transmit a signal from the electrical terminal 86 to a temperature sensor 130 disposed near the outlet of the tube 126. In some aspects, the temperature sensor 130 can be a negative temperature coefficient (NTC) sensor that can detect the temperature of the fluid surrounding the temperature sensor 130. Similar to the end 120, the temperature sensor 130 can extend out of the housing 102 and extend vertically downward.

[0076] As noted above, the mating surface 106 of the fluid texturizing device 100 may also include a drive shaft port 112 disposed in the center of the housing 102. A coupling 117 may extend into the drive shaft port 112. A drive shaft 116 may be mounted in the drive shaft port 112 by the coupling 117 so that the drive shaft is configured to receive rotational motion from the motor 64 disposed in the mounting arm 90. The coupling 117 and / or the drive shaft 116 are fixed in the housing by snap rings that are positioned so as to prevent the drive shaft 116 from moving along a vertical axis. The drive shaft 116 may extend from the first end 102a through the housing 102 to the second end 102b. In some aspects, the drive shaft 116 may be parallel to both the steam injection tube 118 and the tube 126. In order to allow rotational motion to be transmitted to the drive shaft 116, the coupling 117 may include one or more slots 117' at the first end 102a. The end of the drive shaft having the slot 117' can extend into the drive shaft port 112 and can receive the tab 95d of the drive feature 95c. Fig.16A and Fig. 16B As shown, the drive shaft port 95 on the mounting arm will extend into the drive shaft port 112 on the fluid texturizing device 100 so that the tab 95d is positioned within the slot 117'. In this way, the slot 117' on the drive shaft 116 can contact the tab 95d on the mounting arm to allow the drive shaft 116 to be rotatably driven.

[0077] like Fig. 10A and Fig. 10B As shown, the second end 102b of the drive shaft 116 may include a connection feature 121 disposed on the end of the drive shaft 116. In some aspects, as shown in FIG. Fig.11A As shown, the connection feature 121 can be in the form of a cylindrical body with a hollow cavity. An opening provided on the bottom surface of the connection feature 121 allows access to the interior of the hollow body. The connection feature 121 can also include a tab 121a provided therein, as further discussed below, the tab 121a is configured to transfer the rotational motion from the drive shaft 116. In some aspects, the tab 121a extends in a vertical direction along the inner surface of the connection feature 121, so that the corresponding drive shaft can be disassembled and replaced in the connection feature 121 relative to the housing 102 in a vertical direction, while still allowing the rotational motion to be transmitted from the drive shaft 116 to the drive shaft 142 by the connection feature 121, and the drive shaft 142 includes a corresponding tab 142a to the tab 121a. Various engagement features can be envisioned to mechanically couple the connection feature 121 to the drive shaft 142, including tabs, slots, connecting rods, or other coupling mechanisms that can be configured on the connection feature 121 and the drive shaft 142 in a corresponding manner.

[0078] With the drive shaft 116 properly coupled to the drive shaft 142, air can flow from an inlet disposed in the drive shaft to the fluid being textured. In order to provide air to the fluid during the texturing process, an air path 158 is disposed through the drive shaft 116. Depending on the direction of rotation of the drive shaft 116, the air path 158 may be sealed or open. FIG. 19A to FIG. 19C The air path 158 is depicted in an open state, wherein air can flow through the air path 158 and out of the channels 154a, 154b, FIG. 20A to FIG. 20C The air path 158 is depicted in a closed state. The drive shaft 116 includes an air inlet aperture 160 disposed on the first end 116a of the drive shaft 116. The air inlet aperture 160 is configured to allow air to enter the air path 158 and pass downwardly to the second end 116b of the drive shaft 116 so as to incorporate the air into the fluid being textured. In one aspect, the number of inlets 160 can vary from a single inlet to a plurality of inlets. Figure 5 and Fig. 7A As shown in the figure, air is introduced into the inlet 160, and the opening 161 and the channel 163 appear between the coupling 117 of the texturizing device 100 and the beverage brewing device 10. These gaps are large enough to allow air to enter the inlet 160 without the need for a dedicated channel. However, it is possible to use a dedicated channel provided in the fluid texturizing device 100 to supply air to the inlet 160 and should be considered within the scope of the present disclosure.

[0079] At least one circumferential slot 164 is also disposed within the first end 116a of the drive shaft 116. In the illustrated embodiment, the drive shaft 116 includes two slots, however only one slot 164 is shown and described. It should be understood that additional slots may have the same configuration. The circumferential slot 164 illustrated is in the form of a cam slot disposed circumferentially around the drive shaft 116. The slot 164 extends partially around the drive shaft 116 and is oriented at an angle relative to the longitudinal axis so as to act as a cam, wherein rotation of the coupling 117 relative to the drive shaft 116 causes linear movement of the coupling 117 relative to the drive shaft 116. In some embodiments, the slot 164 may have an angular or spiral shape around the circumference of the drive shaft 116. As stated above, the coupling 117 is disposed within the first end 116a of the drive shaft and is configured to move axially within the drive shaft 116. In order to convert the rotational motion of the drive shaft 116 into the axial motion of the coupling 117, the coupling 117 includes a post 166 disposed in a circumferential slot 164. Due to the circumferential and axial positions of the slot 164, when the drive shaft 116 rotates, the post 166 moves in the slot 164, thereby causing the coupling 117 to move axially in the drive shaft 116. The movement of the post 166 in the slot 164 depends on the rotation direction of the drive shaft 116. In one aspect, clockwise rotation of the drive shaft 116 will cause the coupling 117 to move vertically upward in the drive shaft 116, while counterclockwise rotation of the drive shaft 116 will cause the coupling 117 to move vertically downward in the drive shaft 116. The coupling 117 may include an inner sleeve and an outer sleeve. The inner sleeve may include one or more posts 166. The post 166 may extend through the slot 164 and be disposed in the outer sleeve. The drive feature 95c can engage the coupling 117 and, when rotated, cause the coupling 117 and the post 166 connected to the coupling 117 to move within the slot 164 toward the terminal end of the slot 164, at which point the coupling 117 will directly transfer the rotational motion to the drive shaft 116.

[0080] When the coupling 117 moves vertically downward within the drive shaft 116, the seal 170 positioned on the end of the coupling 117 can contact the inner surface 169 of the drive shaft 116 to seal the air path 158. The seal 170 can be disposed on the bottom surface of the coupling 117 located within the drive shaft 116. Fig.19CAs shown, the seal 170 is in the form of a circular plate fixed to the bottom of the coupling 117, so that when the coupling 117 is vertically raised in the drive shaft 116, a circumferential gap G is formed between the inner surface 169 of the drive shaft 116 and the seal 170. The gap G is arranged near the inlet 160, so that air can enter the drive shaft 116 through the inlet 160 and reach the air path 158 through the gap G. The seal 170 can be a silicone seal or a rubber seal, which can continuously prevent air from flowing between the seal 170 and the inner surface 169. Fig. 20A As shown, seal 170 may be axially displaced to contact inner surface 169, which blocks air flow through air path 158. When air path 158 is blocked, only steam and / or mechanical agitation is transmitted to the fluid being textured, which may produce a variety of different fluid texture types.

[0081] Return to reference Figure 8 and Fig. 9 In order to secure the fluid texturing device 100 to the mounting arm 90, the mating surface 106 may also include mating grooves 114a, 114b corresponding to the tabs 99a, 99b on the mounting arm 90. The mating grooves 114a, 114b are disposed on opposite sides of the drive shaft port 112 and extend downwardly into the housing 102. The mating grooves 114a, 114b may have a shape and size corresponding to the shape and size of the tabs 99a, 99b. Fig.14 As shown, the mating grooves 114a, 114b can each have a flange 115a, 115b formed therein, and when the tabs 99a, 99b are inserted into the mating grooves 114a, 114b, the flanges 115a, 115b are engaged by the tabs 99a, 99b. As stated above, in order to remove the tabs 99a, 99b from the mating grooves 114a, 114b, the tabs 99a, 99b are radially displaced inward by the buttons 98a, 98b, thereby removing the tabs 99a, 99b from the flanges 115a, 115b. Figure 5 and Fig. 7A As shown, the mounting arm 90 may include an opening 161 disposed at a bottom of the mounting arm and a passage 163 extending from the opening 161 through the mounting arm 90 to the drive shaft port 95 to supply air to the air path within the drive shaft.

[0082] In order to act on the fluid surrounding the fluid texturing device 100, such as Figure 8 , Fig. 10A and Fig. 10B As well as Figures 12 to Fig.13As shown, the fluid texturization device 100 also includes an agitator assembly 104, which is detachably coupled to the second end 102b of the housing 102. The agitator assembly 104 generally includes an agitator 140, a drive shaft 142, and an agitator cover 143. The agitator cover 143 can have various configurations, but it is generally configured to surround the agitator 140. In some aspects, the agitator cover 143 can have a truncated cone shape extending radially outward from the housing 102. The agitator cover 143 can include a plurality of tabs 132 disposed at its outer circumference and extending downward from the agitator cover 143. The tabs 132 can act as spacers to form a space between the bottoms of the fluid containers so that the agitator 140 does not contact the bottoms of the fluid containers. Therefore, the height of the tabs 132 can be greater than the height of the agitator 140. There can be gaps between each of the tabs in the plurality of tabs 132 to allow the fluid to pass between the tabs 132, thereby interacting with the agitator 140. In addition to the tabs 132, the agitator cover 143 may further include at least one or more holes 150 and 150' disposed on a top surface thereof. As will be explained in detail below, the holes 150 and 150' may allow air to interact with the agitator 140.

[0083] like Fig. 11B and Fig. 12A As shown, the blender cover 143 may also include separate holes 146, 148 that may be separated by blades 149. The blades 149 are shown extending radially outward from the central housing 147 of the blender cover 143. However, the blender cover may include any number of blades positioned in any position, or in other embodiments, the blender cover may be completely devoid of blades. In the presence of blades, the holes 146, 148 may be positioned to allow the end 120 of the steam injection tube 118 and the temperature sensor 130 to pass through the blender cover 143 so that the end 120 and the temperature sensor 130 can be disposed near the blender 140. In some embodiments, as shown in FIG. Fig. 12A As shown, the drive shaft 116 may include an opening 152 located at an end of the drive shaft 116 located within the agitator assembly 104 .

[0084] Fig. 12BAn embodiment of an agitator assembly 32' is shown, wherein the drive shaft 142' includes a cover 143a' that is positioned at an opening 152 of the drive shaft 116 within the agitator assembly 104'. The agitator assembly 104' is substantially similar to the agitator assembly 104. Therefore, similar components will not be described in detail. The agitator assembly 104' generally includes an agitator 140', a drive shaft 142', an agitator cover 143', an aperture 146', a central housing 147', and an aperture 148'. As shown, no blades extend between the central housing 147' and the agitator cover 143' except for the portion where the apertures 146', 148' are provided.

[0085] To secure the blender assembly 104 to the housing 102, the blender cover 143 may include attachment features that mate with corresponding attachment features in the housing 102. Fig.13 As shown, in one embodiment, the attachment member can be in the form of a magnetic element. For example, the housing 102 can include one or more magnets 109 disposed in the bottom surface 107, and the blender cover 143 can also include one or more magnets 144 disposed therein and aligned with the magnets 109 in the housing 102. The magnets 144 in the blender cover 143 can be disposed within a central housing 147 of the blender cover. As will be discussed further below, the central housing 147 can also retain the drive shaft 142 therein. The magnets 144 can circumferentially surround the drive shaft 142 to help align the drive shaft 142 with the drive connection feature 121 on the housing 102. In particular, when the blender assembly 104 is magnetically engaged with the housing 102, the end 120 and the temperature sensor 130 will pass through the blender cover 143, and the drive shaft 142 will align with and extend into the connection feature 121.

[0086] In addition to aligning the drive shaft 142 with the connection feature 121, the drive shaft 142 may also include a lumen in the form of an air path 168 therein, through which air may be provided to the fluid to be textured. The agitator assembly 104 may also include arms 145a and 145b, which are disposed on opposite sides of the drive shaft 142 and are disposed perpendicular to the drive shaft 142. In addition, passages 154a, 154b may be disposed in arms 145a, 145b, respectively, and act as an air path that is fluidically coupled to the air path 168 of the drive shaft 142. As stated above, when the agitator assembly 104 is connected to the drive shaft 116, air may reach the drive shaft 142 through the drive shaft 116. When air passes through the air path 158 and enters the agitator assembly 104 downward, the air enters the air path 168 disposed in the drive shaft 142 of the agitator assembly 104. The air can then pass through channels 154a, 154b configured as additional air paths disposed within the mixing arms 145a, 145b disposed on the drive shaft 142. This allows for specific volumes of air to be incorporated into the fluid being textured at different agitation speeds.

[0087] like Fig.13 As shown, the drive shaft 142 is rotatably disposed in a central housing 147 in the agitator cover 143. The agitator 140 can be disposed at the terminal end of the drive shaft 116 and can be disposed on support members 156a, 156b extending from channels 154a, 154b, respectively. Although the agitator assembly 104 is shown as having two channels 154, one or more channels 154 can be configured. For example, in some embodiments, 3, 4, 5, or 6 channels 154 can be configured. Each channel 154 can be disposed in a corresponding mixing arm 145. The agitator 140 can be in the form of a helical metal spring disposed around the support members 156a, 156b to form a torus-like shape. In one aspect, in addition to the helical metal spring, the design of the agitator can also include other embodiments including blades, paddles, and other linear structures, such as balloon agitators, French agitators, ball agitators, flat agitators, spiral agitators, and conical agitators. As Fig.13 , the drive shaft 116 can be configured to position the agitator 140 at least partially below the tip 120 and the temperature sensor 130, but above the bottom surface of the tab 132 to prevent the agitator 140 from contacting the bottom surface of the fluid container. The drive shaft 116 can include a lumen therein forming an air path 158 between the first and second ends thereof. The air path 158 can pass through the drive shaft 116 and exit the agitator assembly 104 via passages 154a, 154b.

[0088] To control the operation of the beverage brewing system, a user interface may be used to input a desired fluid texture to be produced. Fig.18 An embodiment of a user interface 200 is shown. As shown, the user interface 200 shown includes a power button 202, a start-stop button 204, a fluid type interface 206, a texture type interface 208, and a temperature level interface 210. The user interface can be connected to a processor, which in turn controls a steam source and a stirring motor. In some aspects, the fluid type interface 206 can represent different variations of alternative fluids of milk and similar milk. Since different types of milk have different properties (e.g., density), the type of fluid to be textured should be selected to obtain the best fluid texture. The type of fluid can be changed using a control 212 provided on the user interface 200. The fluid type texture interface 208 can be used to determine the level of the desired fluid texture. For example, cappuccino may require more foam than latte. The type of desired texture can be changed using a control 214 provided on the user interface 200. In addition, the desired fluid temperature can be selected by the temperature level interface 210, and the desired fluid temperature can be changed by the control 216 provided on the user interface 200. Using input from interfaces 206, 208, 210, the proper fluid texture may be automatically achieved by allowing the system to run a predetermined program (including agitation speed and steam input) for a period of time.

[0089] In order to obtain the desired fluid texture, the fluid texturizing device can be configured to operate in different stages, wherein each stage has a different rotation per minute (RPM). In some embodiments, the fluid texturizing device can operate with different rotation directions, so that the agitator can rotate in a first direction (e.g., clockwise) in one stage and in a second direction (e.g., counterclockwise) opposite to the first direction in another stage. In some embodiments, the desired fluid texture can be achieved by rotating the agitator continuously or intermittently in the same direction, or by rotating the agitator continuously or intermittently in different directions. These stages can be configured by modifying these settings to obtain the desired performance.

[0090] Two or more changes in RPM and / or direction between different stages throughout the fluid texturization process may produce different microfoam textures. In some aspects, a first processing operation for all microfoam textures may begin at a high RPM speed in a first rotational direction, whereby both steam and air are instantaneously combined before combining with the fluid contained in the container 40. Then, a second processing operation for each microfoam texture is based on the desired fluid texture and may include high RPM rotation, low RPM rotation, or no rotation of the agitator 140 in either rotational direction. The amount of simultaneous operating time (i.e., steam processing and agitator rotation) may be indicated by a user selection on the user interface 200, thereby producing different levels of microfoam texture for each milk-based beverage input. By performing multiple stages of heating and stirring, the texturized fluid can be heated quickly, thereby providing small bubbles and a desired texture, while also preventing the fluid from overheating and causing undesirable results.

[0091] Fig. 22 An example of a texturization process with different stages is depicted in Graph 250. Graph 250 depicts a fluid texturization process including a first stage 252 and a second stage 254. Line 256 represents the duration of the first stage 252 and line 258 represents the duration of the second stage 254. It is important to note that the duration of each stage can vary depending on the desired fluid texture. Line 260 represents the increase in temperature of the fluid being textured in the first stage 252 over time. Line 262 represents the increase in temperature of the fluid being textured in the second stage 254 over time.

[0092] During the fluid texturization process, the fluid (e.g., water) stored in the reservoir 32 is pumped into the steam source 60, where the fluid is evaporated and directed as pressurized steam through the dedicated tube 94a to the steam injection tube 118 and the outlet 122 in the removable agitator cover 143. Steam continuously passes through the steam injection tube 118 and flows out through the outlet 122 in the end 120, where the steam is delivered to the fluid in the fluid container 40. At the same time, when the steam is delivered through the steam injection tube 118, the motor 64 drives the agitator 140 to form a fluid vortex in the container 40. Fig. 22250 , during the first stage 252, the agitator is rotated in a clockwise direction at, for example, 3000 RPM. The clockwise rotation of the agitator opens the seal 170 in the air path 158, allowing air to flow through the air path 158 and into the fluid being textured. This high rotation speed of the agitator 140 can also generate deep vortices in the fluid container 40. In some aspects, the fluid container 40 can include a lid (described below) with a hole that allows the housing 102 to enter the container 40, but prevents overflow from the container during the texturization process.

[0093] When the first stage 252 ends, the fluid texturization process may not be fully completed. It may be necessary to further texturize the fluid in the second stage 254 to ensure appropriate results. In the second stage 254, compared with the first stage 252, the agitator 140 also rotates in a clockwise direction at a lower RPM (e.g., 1500RPM) to keep the air duct 158 ​​open to allow air to pass through the drive shaft 116 and enter the fluid. The lower RPM of the second stage 254 can also produce a vortex shallower than the above-mentioned vortex. This allows steam, air and agitator 140 to texturize the fluid within the remaining amount of time of the fluid texturization process.

[0094] As stated above, not every texturizing process requires that the air path 158 remain open throughout the entire process. Fig.23 Describes the fluid texturing process of latte coffee, which does not require Fig. 22 280. As depicted in graph 280, during the first stage 282, the agitator rotates in a clockwise direction at, for example, 3000 RPM. Similar to the first stage 252 in graph 250, the clockwise rotation of the agitator opens the seal 170 in the air path 158, allowing air to flow through the air path 158 and into the fluid being textured. Line 286 represents the duration of the first stage 282, and line 288 represents the duration of the second stage 284. Line 290 represents the increase in temperature of the fluid being textured over time in the first stage 282. Line 292 represents the increase in temperature of the fluid being textured over time in the second stage 284.

[0095] When the first stage 282 ends, the fluid texturizing process may not be fully completed. A second stage 284 may be needed to further texturize the fluid to ensure proper results. In the second stage 284, the agitator 140 is also rotated in a counterclockwise direction at a lower RPM (e.g., 1500 RPM) compared to the first stage 282, thereby sealing the air duct 158 ​​using the seal 170 and preventing air from entering the fluid through the drive shaft 116. This allows the steam and agitator 140 to texturize the fluid for the remaining amount of time of the fluid texturizing process.

[0096] It should be noted that when the blender 140 is subsequently used with steam, the amount of air incorporated into the fluid can be changed by adjusting the RPM of the blender 140. In one aspect, the RPM at which the blender 140 rotates can be controlled by the user through a user interface. In addition, in one aspect, the temperature of the output steam and / or the target temperature of the fluid being textured can be manually controlled by the user. For example, a user can select a specific texturizing process, such as a latte with oat milk. The fluid texturizing device will automatically determine the target temperature based on the selected texturizing process parameters. However, if the user requires a hotter or colder (e.g., within a range of -5°C of the target temperature to +5°C of the target temperature) textured fluid, the user can also choose to change the target temperature.

[0097] In another embodiment, a container is provided for use with a fluid texturizing apparatus. Due to the agitation of the fluid and the release of vapor during the fluid texturizing process, it is beneficial to seal the container in which the fluid texturizing apparatus is operating. FIG. 17A to FIG. 17E The fluid texturizing device 100 is shown used in conjunction with a cover 290 and a container 40 to form a fluid texturizing assembly 101. Although the cover can have a variety of configurations, in the illustrated embodiment, the cover 290 generally includes an aperture 292 disposed within a central region of the cover 290 and a seal 294 disposed around the cover 290. The aperture 292 can be shaped to correspond to the cross-section of the housing 102 so that fluid does not escape from the space between the housing 102 and the cover 290. The fluid texturizing device 100 can be inserted into the aperture 292 by removing the agitator assembly 104 from the housing and placing the second end 102b of the housing into the aperture 292. Fig. 17B As shown, after the housing 102 passes through the hole 292, the agitator assembly 104 can then be connected to the housing 102. Even though the hole 292 is shaped to correspond to the cross-section of the housing 102, the housing 102 can freely slide relative to the cover 290 along the vertical axis when set into the hole 292.

[0098] In one aspect, the lid 290 of the container 40 can be designed so that the housing 102 can be inserted into the lid 290 without removing the agitator assembly 104. In an exemplary embodiment, the lid 290 can include two separate halves / portions that are configured to be mounted to the container 40, located on either side of the housing 102, so that the housing can be inserted into the container first, and then the two parts of the lid 290 can be inserted around the housing 102 onto the container 40. The two parts of the lid can abut against each other when placed on the container 40, and effectively cover the entire opening of the container 40 (except for the hole in which the housing 102 is located) when placed on the container 40. Alternatively, the lid 290 can include a hinge structure in which the two parts of the lid 290 are attached to the outer ring of the lid and open / close to enable the housing 102 to be installed or removed from the lid 290 without removing the agitator assembly 104. The two-part cover 290 will allow the fluid texturizing apparatus 100 to be permanently secured to the housing 102 and the agitator assembly 104 relative to one another.

[0099] After the housing 102 is disposed within the cover 290, the cover 290 can be positioned on the container 40. The container 40 may include a fluid 42 to be textured, such as milk or a milk-like fluid, disposed within the container. A seal 294 on the cover 290 may abut against the edge of the container 40 to prevent the fluid 42 from escaping from the container 40 during the texturizing process. Fig.17D As shown, the cap 290 extends across the upper opening of the container 40 to close the container. In one embodiment, the container 40 may include a nozzle 45 not covered by the cap 290, which allows a user to dispense the fluid 42 from the container 40 without removing the cap 290 from the container 40.

[0100] like Fig.17E As shown, after the housing 102 is fully pushed into the container 40, the fluid texturizing assembly 101 can be positioned below the mounting arm 90 of the beverage brewing device 10 so that the housing 102 is aligned with the mounting arm 90. Fig.17FAs shown, after the fluid texture assembly 101 is disposed below the mounting arm 90, the housing 102 can be displaced upward along the vertical axis to connect the housing 102 to the mounting arm 90. During the connection process and the texturing process, the container 40 can be placed on a support surface. Alternatively, the entire container 40 / housing 102 assembly can be lifted by the user to connect the housing 102 to the mounting arm 90, after which the container can be lowered to the support surface. In one embodiment, the agitator assembly 104 (including the tab 132) does not contact the bottom surface of the container 40 during the texturing process. As described above, in order to remove the container 40 to obtain the textured fluid 42, the buttons 98a, 98b can be pressed to release the housing 102 from the mounting arm 90. In the case of including a nozzle 45, the user can pour the textured fluid from the nozzle 45 without removing the cover 290 or the housing 102.

[0101] In certain aspects, the beverage brewing apparatus 10 runs a confirmation check to ensure that the fluid texturizing device 100 is properly secured to the beverage brewing apparatus 10 . Fig.21 300 is shown for ensuring that the fluid texturizing device 100 is connected and set up for the texturizing process. As shown in step 302, when the beverage brewing device 10 is powered on (i.e., plugged into a 120 volt (V) wall outlet), the beverage brewing device 10 is in a low power mode. In the low power mode at step 302, the buttons on the user interface are turned off, and the power button is at a 10% power level to illuminate the power button. When the power button is pressed to turn on the beverage brewing device 10 at step 304, a controller within the beverage brewing device 10 can determine whether the fluid texturizing device 100 is attached to the beverage brewing device 10. The processor can determine the connection status of the fluid texturizing device 100 by using the electrical connection between the electrical terminals 80, 86 respectively disposed on the mounting arm 90 and the housing 102. If no signal from the temperature sensor 130 is detected through the electrical terminals 80, 86, the processor can activate a notification at step 310, such as flashing illuminated text that reads "Install Whisk". Additionally, all other buttons and lights on the user interface will be disabled.Once the fluid texturizing apparatus 100 is properly installed, the controller may activate the user interface at step 308 and allow the user to select their texturizing preferences to begin the texturizing process.

[0102] Although the above description describes the fluid texturizing device 100 in combination with a beverage brewing apparatus, the fluid texturizing device 100 may also be implemented as a stand-alone device. When implemented as a stand-alone device, the fluid texturizing device may include a separate reservoir and a separate heater for generating steam independently of the beverage brewing system.
