Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a flow guide and a foamer. Background Technology

[0002] In the field of food processing equipment technology, rotary foamers use their own rotational motion to agitate liquids (such as milk, soy milk, and fruit juice), thereby mixing the liquid with air to form foam and enrich the texture. However, in the application of existing rotary foamers, the air intake and foam fineness during the foaming process are often difficult to control due to user operation techniques, resulting in variations in foam quality (such as thickness and fineness) each time the foamer is used, making it difficult to maintain stability.

[0003] Specifically, in existing technologies, rotary foamers cannot effectively separate and control the air intake process and the foaming process (the process of converting the drawn-in air into fine foam). These two processes often occur simultaneously during operation. That is, while the liquid is being foamed, new air enters, making it difficult to control the air intake and foaming ratio. Some air is not fully circulated and refined, and new air is drawn into the liquid and mixed with it, resulting in uneven foam distribution and difficulty in controlling the quality of the foam produced by the rotary foamer. This leads to coarser foam, affecting the overall quality of the foam. Simultaneously, the liquid generates vortices under the influence of the rotary foamer. These vortices increase the contact area between air and liquid and make it difficult to control the air entrainment into the foamer's channels, further interfering with the controllability of the air intake and affecting the stability of the air intake volume.

[0004] Therefore, how to effectively control the air intake and vortex formation of the foamer to improve foam quality is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a flow guide and a bubbler, which aims to overcome the problems existing in the prior art.

[0006] This utility model provides a flow guide component, applied in a bubbler, comprising:

[0007] A funnel-shaped fan blade is disposed above the rotating whipping head of the foamer. The central axis of the funnel-shaped fan blade coincides with the rotation axis of the rotating whipping head. The funnel-shaped fan blade includes at least one sub-fan blade.

[0022] The upper cover has a non-circular anti-rotation through hole in the middle. The inner side of the sub-fan blade extends upward and is connected to a lifting rod. The lifting rod is inserted into the anti-rotation through hole through an anti-rotation part at its upper end. The top of the anti-rotation part has a vertically upward threaded rod.

[0049] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0050] Please see below. Figures 1-3 The present invention provides a flow guide component, which is applied in a bubbler, and specifically includes:

[0051] The funnel-shaped fan blade 10 is disposed above the rotating whipping head 20 of the bubbler. The central axis of the funnel-shaped fan blade 10 coincides with the rotation axis of the rotating whipping head 20. The funnel-shaped fan blade 10 includes at least one sub-fan blade 11.

[0052] A deceleration baffle 30 extends vertically downward along the edge of the sub-fan blade 11 and is disposed on the outside of the rotating whipping head 20, with the surface of the deceleration baffle 30 facing the rotation direction of the rotating whipping head 20.

[0053] In this embodiment, by placing the funnel-shaped fan blade 10 above the rotating frothing head 20 of the foamer, liquid flow can be effectively guided. When the rotating frothing head 20 froths the liquid, under the action of centrifugal force, the liquid level in the center drops and the liquid level at the edge rises. At this time, the surrounding liquid can be quickly replenished from the top opening of the funnel-shaped fan blade 10, forming a stable liquid flow circulation and optimizing the foaming effect. In addition, the bubbles formed when frothing the liquid will also flow preferentially to the center of the funnel-shaped fan blade 10 through the top opening, allowing large, unrefined bubbles to re-enter the rotating frothing head 20 for circulation and refinement, forming secondary foaming. This refines the large bubbles, improves the foaming effect, and ensures that the foam is fine and evenly distributed.

[0054] This embodiment also uses a deceleration baffle 30 below the sub-blades 11 of the funnel-shaped fan blade 10 to block the flow of liquid, thereby reducing the rotation speed of the liquid, suppressing the formation of vortices, improving the controllability of the liquid air intake, further optimizing the foaming effect, and ensuring the stability of foam quality. Simultaneously, it avoids the phenomenon of the rotating foaming head 20 being exposed to the air due to vortices, ensuring that the rotating foaming head 20 is in full contact with the liquid, allowing for faster replenishment of the liquid entering the rotating foaming head 20, thereby increasing the liquid flow rate participating in the circulating foaming process, improving foaming efficiency and foaming effect.

[0055] In a specific embodiment, the number of sub-fan blades 11 (which can be understood to correspond to the number of deceleration baffles 30) and the size of the flow guiding gap between the sub-fan blades 11 can be adjusted according to actual needs to ensure the best deceleration and flow guiding effect. For example, the funnel-shaped fan blade 10 can be set to include two sub-fan blades 11 or three sub-fan blades 11, etc.

[0056] In one embodiment, the curved surface of the sub-fan blade 11 extends outward spirally from the bottom to the top. Combined with the characteristic that the top opening diameter of the funnel-shaped fan blade 10 is larger than the bottom opening diameter, it can not only increase the contact area between the fan blade surface and the liquid, but also enhance the liquid guiding effect. This allows the liquid to flow more smoothly along the curved surface of the fan blade to the center of the funnel-shaped fan blade 10 when the rotating whipping head 20 is rotating, and then flow back to the rotating whipping head 20. This promotes the circulation and refinement of the liquid, and improves the uniformity of foaming and the stability of the foam.

[0057] In a specific embodiment, the edges of the top and bottom openings of the funnel-shaped fan blade 10 can be flush, allowing liquid and bubbles to be guided more evenly through the curved surface of the funnel-shaped fan blade 10 and flow towards the center of the funnel-shaped fan blade 10 for fluffing and refining. Of course, in other specific embodiments, the edges of the top and bottom openings of the funnel-shaped fan blade 10 may not be flush, but rather the edge height may be set to change continuously along an arc (spiral).

[0058] In one embodiment, the deceleration baffle 30 has a concave arc-shaped structure.

[0059] In this embodiment, the concave arc design of the deceleration baffle 30 can effectively slow down the liquid flow rate and suppress the generation of vortices, thereby reducing the turbulence of the liquid in the foaming device, ensuring smooth liquid flow, and improving the uniformity and stability of the foam.

[0060] In a specific embodiment, as can be seen from the outward spiral extension of the curved surface of the funnel-shaped fan blade 10 from the bottom opening to the top opening, its sub-fan blades 11 extend outward spirally from bottom to top. Based on this, the sub-fan blades 11 extend vertically downward from their arc-shaped trailing edge, thus forming a concave arc-shaped deceleration baffle 30. Compared to a straight-plate deceleration baffle 30, the concave arc design more effectively slows down the liquid flow rate, thereby suppressing the formation of vortices, ensuring smooth liquid flow, further optimizing the fineness and durability of the foam, and improving the overall foaming effect.

[0061] Of course, in other embodiments, the shape of the deceleration baffle 30 is not limited to a concave arc shape. Depending on the actual application scenario, other shapes that can play a deceleration role can be selected. For example, a non-smooth structure such as a wavy curved surface can be used.

[0062] In specific application scenarios, the funnel-shaped fan blade 10 and the deceleration baffle 30 can be integrally molded using injection molding or other processes. This simplifies the production process, reduces manufacturing costs, and improves structural strength, ensuring the integrity and stability of the structure, thereby further enhancing the performance and durability of the bubbling device.

[0063] In addition, the height and width of the deceleration baffle 30 can be optimized according to the actual application scenario to further reduce the liquid rotation speed, ensure that the liquid is evenly distributed in the foaming device, avoid the problem of uneven foam caused by local excessively fast flow, and thus comprehensively improve the foaming effect and foam stability.

[0064] This utility model embodiment also provides a foamer, including the flow guide as described above. The foamer can be connected to and driven by a handheld part 40 to a rotating foaming head 20 to foam the liquid; or, it can be connected to and driven by a foaming cup 50 to a rotating foaming head 20 to foam the liquid.

[0065] It is understood that the handheld part 40 has a built-in drive device, the output end of which is connected to the rotating rod 21 and drives the rotating rod 21 to rotate. When the handheld part 40 is provided in the foamer, the rotating frothing head 20 can be rotated and connected to the bottom of the handheld part 40 by rotating the rod 21, and the liquid air intake during the frothing process can be adjusted by controlling the height of the rotating frothing head 20.

[0066] Specifically, in practical applications, the generation of vortices makes it difficult to control the air intake of the foamer. This embodiment of the invention improves the control effect on the air intake of the liquid by setting a deceleration baffle 30 to suppress vortex generation. Based on this, when it is necessary to increase the air intake of the liquid, the height of the handheld part 40 can be manually raised to reduce the deceleration effect of the deceleration baffle 30 and make it easier for the liquid to form vortices. This allows the rotating frothing head 20 to approach the surface of the liquid level line, increasing its contact area with air, thereby agitating the liquid surface and mixing with air to achieve air intake, and thus promoting foam formation.

[0067] In addition, the rotational speed of the rotating rod 21 can be increased, thereby increasing the rotational speed of the rotating head 20, which in turn increases the rotational speed of the liquid, making it easier to form vortices, increasing the contact area between the rotating head 20 and the air, and thus bringing more air into the liquid, thereby increasing the air intake.

[0068] In one specific embodiment, a hollow mounting sleeve rod 12 extends upward from the inner side of the sub-fan blade 11. The funnel-shaped fan blade 10 is sleeved on the rotating rod 21 through the mounting sleeve rod 12 and fixedly installed in the mounting hole at the lower end of the handheld part 40.

[0069] In this embodiment, the funnel-shaped fan blade 10 is sleeved on the rotating rod 21 by the mounting sleeve 12 and fixed by the mounting hole at the lower end of the hand-held part 40, so that the funnel-shaped fan blade 10 can rise and fall synchronously with the rotating beating head 20, thereby achieving more precise control over the cotton beating process.

[0070] Specifically, an installation gap 13 can be formed by cutting the side of the mounting sleeve 12, and the width of the installation gap 13 can be set to be greater than the width of the rotating rod 21. This allows the mounting sleeve 12 to be directly fitted onto the rotating rod 21 through the installation gap 13 after the rotating hair-beating head 20 is fixed below the handheld part 40 via the rotating rod 21, improving the convenience and efficiency of installation. In cases where the funnel-shaped fan blade 10 is not needed or needs to be replaced, the installation gap 13 of the mounting sleeve 12 allows the funnel-shaped fan blade 10 to be directly disassembled or installed onto the rotating rod 21 without first removing the rotating hair-beating head 20, thus improving the user experience.

[0071] Of course, the installation gap 13 can be omitted. Instead, a through hole is provided in the center of the funnel-shaped fan blade 10 in the vertical direction. The funnel-shaped fan blade 10 is first installed in the mounting hole at the lower end of the handheld part 40. Then, the rotating rod 21 connecting the rotating firing head 20 is passed through the through hole and fixed at the lower end of the handheld part 40. With this setting, when the funnel-shaped fan blade 10 needs to be disassembled, the rotating firing head 20 needs to be removed first.

[0072] In another specific embodiment, the upper end of the mounting sleeve 12 is provided with a snap-fit ​​part 121, and the inner side of the mounting hole has a snap-fit ​​groove whose shape matches the snap-fit ​​part 121. The side of the snap-fit ​​part 121 is provided with an open through groove 122. Thus, through the cooperation of the snap-fit ​​groove and the snap-fit ​​part 121, a stable connection between the funnel-shaped fan blade 10 and the handheld part 40 can be ensured. The open through groove 122 on the side of the snap-fit ​​part 121 allows the snap-fit ​​part 121 to be finely adjusted in position when under force, providing redundant installation space, facilitating the installation and disassembly of the funnel-shaped fan blade 10, improving the maintenance efficiency of the device, and also making it easy for users to disassemble for cleaning and maintenance, thus improving the user experience.

[0073] In specific application scenarios, the number and size of the open through slots 122 can be flexibly adjusted according to actual needs to meet the installation accuracy and maintenance convenience under different working conditions, ensuring the long-term stable operation of the device. For example, since the funnel-shaped fan blade 10 below the handheld part 40 is hollow, and its top snap-fit ​​part 121 also presents a cylindrical structure (or annular structure), the number of open through slots 122 can be set to three. In this way, the snap-fit ​​part 121 is divided into three parts by the open through slots 122. By utilizing the segmented design of the open through slots 122, redundant installation space is provided, and the segmented fine adjustment of the snap-fit ​​part 121 is realized, which facilitates installation and disassembly.

[0074] Furthermore, an annular housing support ring 123 can be formed by protruding outward from the mounting sleeve 12 on the lower side of the snap-fit ​​portion 121 to support the weight of the handle portion 40 mounted on the mounting sleeve 12, thereby enhancing the stability of the overall structure. It is understood that, due to the presence of the open through groove 122, the housing support ring 123 also presents a segmented structure.

[0075] In addition, in other embodiments, besides snap-fit, other connection methods can be used to fix the funnel-shaped fan blade 10 to the handheld part 40. For example, corresponding threads can be provided in the mounting hole of the handheld part 40 and on the top outer surface of the mounting sleeve 12, and the two can be fixedly connected by threaded engagement.

[0076] As mentioned above, the frother provided in this embodiment of the utility model can be equipped with a handheld part 40 or a frother cup 50. Combined with... Figure 4 As shown, when a foaming cup 50 is installed in the foamer, the rotating whipping head 20 can be rotatably installed at the bottom center of the foaming cup 50. The foaming cup 50 drives the rotating whipping head 20 to rotate, and controls the foaming process. It can also be understood that the foaming cup 50 has a built-in drive device to connect to and drive the rotating whipping head 20 to rotate.

[0077] Combination Figures 5-7As shown, in one embodiment, a first fixing rod 51 extending upward is provided in the middle of the foaming cup 50, and the rotating whipping head 20 is sleeved on the first fixing rod 51. An anti-rotation key 511 is provided at the top of the first fixing rod 51.

[0078] The inner side of the sub-fan blade 11 extends upward and is connected to a first mounting cap 14. The bottom of the first mounting cap 14 is recessed and has an anti-rotation groove for engaging with the anti-rotation key 511.

[0079] In this embodiment, the rotating atomizing head 20 is sleeved on the first fixed rod 51 and rotates (the first fixed rod 51 remains stationary). The anti-rotation key 511 on the top of the first fixed rod 51 engages with the anti-rotation groove at the bottom of the first mounting cap 14, thus fixing the funnel-shaped fan blade 10 to the first fixed rod 51. To increase the air intake of the liquid, the rotational speed of the rotating atomizing head 20 can be increased, making it easier for the liquid to form a vortex, thereby drawing more air into the liquid and increasing the air intake.

[0080] In a specific embodiment, the anti-rotation key 511 and the anti-rotation groove are not circular in shape. For example, the anti-rotation key 511 and the anti-rotation groove can be rectangular in cross-section. After the anti-rotation key 511 is inserted into the anti-rotation groove, it can no longer rotate, thereby fixing the funnel-shaped fan blade 10 to the first fixed rod 51 so that it will not rotate with the rotation of the rotating agitator 20 (if the funnel-shaped fan blade 10 is not fixed, the rotating agitator 20 will drive the liquid to rotate, and the liquid will drive the funnel-shaped fan blade 10 to rotate).

[0081] Combination Figure 8 and Figure 9 As shown, in another embodiment, a second fixing rod 52 extending upward is provided in the middle of the foaming cup 50, the rotating whipping head 20 is sleeved on the second fixing rod 52, and the top surface of the second fixing rod 52 is provided with threads 521;

[0082] The inner side of the sub-fan blade 11 extends upward and is connected to a second mounting cap 15. The bottom of the second mounting cap 15 is recessed and has a threaded groove for engaging with the thread 521.

[0083] In this embodiment, the rotating agitator 20 is sleeved on the second fixed rod 52 and rotates (the second fixed rod 52 remains stationary). The thread 521 of the second fixed rod 52 engages with the threaded groove at the bottom of the second mounting cap 15, thereby adjusting the height of the guide by controlling the rotation direction of the rotating agitator 20, thus controlling the air intake of the liquid.

[0084] Specifically, when the rotating head 20 is rotated clockwise, the liquid also rotates clockwise, causing the guide to move upward along the thread 521 of the second fixed rod 52 until the guide disengages from the thread 521. At this point, the guide will rotate synchronously with the liquid, and the deceleration baffle 30 will no longer decelerate the liquid. Therefore, the liquid will more easily form a vortex, thereby increasing the air intake.

[0085] Once the required air intake is achieved, the liquid rotation direction can be changed by rotating the agitator head 20 counterclockwise. This causes the guide component to reverse, allowing it to re-engage with the threaded groove 521 and move downwards along the threaded groove until it reaches the bottom of the threaded groove 521. At this point, since the threaded groove 521 has reached the bottom, the guide component can no longer rotate along the threaded groove 521 and is effectively fixed to the second fixing rod 52. This allows the deceleration baffle 30 to suppress vortex generation and the funnel-shaped fan blade 10 to guide the liquid, achieving precise control of the air intake, improving foaming efficiency, and enhancing foam quality and stability.

[0086] It should be noted that in specific application scenarios, the rotating whipping head 20 is not limited to moving upward along the thread 521 of the second fixed rod 52 when rotating clockwise and moving downward along the thread 521 of the second fixed rod 52 when rotating counterclockwise. It can also move downward when rotating clockwise and downward when rotating counterclockwise. The specific choice can be determined according to the actual situation.

[0087] In other embodiments, a smooth rotating shaft can be extended above the threaded thread 521, and a limiting structure can be provided at the top of the rotating shaft. With this configuration, after the guide component disengages from the threaded thread 521, it will continue to rotate around the rotating shaft, preventing the deceleration baffle from slowing down the liquid and ensuring it does not leave the range of the second fixed rod 52 under the constraint of the limiting structure. When reverse rotation and re-engagement are required, the guide component will first reverse its rotation around the smooth rotating shaft until the threaded groove and threaded thread 521 are re-aligned, and then move down along the threaded thread 521 to a fixed position, ensuring flexible and stable operation and further improving control accuracy.

[0088] Combination Figures 10-13 As shown, in another embodiment, the frother also includes a top cover 60 adapted to the frother cup 50 and an adjustment knob 70 disposed at the top center of the top cover 60.

[0089] The upper cover 60 has a non-circular anti-rotation through hole 61 in the middle. The inner side of the sub-fan blade 11 extends upward and is connected to a lifting rod 16. The lifting rod 16 is inserted into the anti-rotation through hole 61 through the anti-rotation part 161 at the upper end. The top of the anti-rotation part 161 is provided with a vertically upward threaded rod 162. The adjustment knob 70 is sleeved on the threaded rod 162 through the internal threaded hole.

[0090] In this embodiment, a top cover 60 with an anti-rotation through hole 61 can also be provided above the foaming cup 50, and a lifting rod 16 with an anti-rotation part 161 can be provided in the flow guide. The lifting rod 16 is inserted into the anti-rotation through hole 61 through the anti-rotation part 161, and a threaded rod 162 is provided on the top of the anti-rotation part 161. The adjusting knob 70 is sleeved on the threaded rod 162.

[0091] Based on this, when the rotating head 20 rotates, the guide member cannot rotate with the rotating head 20 due to the restriction of the anti-rotation part 161. Thus, the generation of vortex can be suppressed by the deceleration baffle 30, and the liquid can be guided by the funnel-shaped fan blade 10.

[0092] When it is necessary to increase the air intake, the adjustment knob 70 can be rotated to make the screw hole and the threaded rod 162 of the adjustment knob 70 rotate relative to each other and increase the length of their engagement. Since the lifting rod 16 cannot rotate, the lifting rod 16 will be dragged by the screw hole (thread) along the anti-rotation through hole 61 under the action of the reaction force, thereby driving the guide to rise, thus weakening the suppression effect of the deceleration baffle 30 on the vortex and increasing the liquid air intake brought by the vortex.

[0093] When the air intake reaches the required level, rotating the adjustment knob 70 in the opposite direction will cause the lifting rod 16 to move in the opposite direction (downward) within the anti-rotation through hole 61 until it reaches the required guide position. This allows the deceleration baffle 30 to be used again to suppress vortex formation, thereby achieving controllability of increasing the liquid air intake, further optimizing the foaming effect, and ensuring the stability of foam quality.

[0094] Furthermore, in a specific embodiment, a third fixing rod extending upward can be provided in the middle of the foaming cup 50, and an installation groove that cooperates with the third fixing rod can be provided at the bottom of the lifting rod 16 to ensure that the lifting rod 16 remains stable during the rising or falling process.

[0095] This utility model embodiment can effectively separate and control the air intake process and the foaming process of the liquid by controlling the flow guide, avoiding the conflict between the two working processes. Air is only introduced when needed, and while foaming the liquid, the new air intake is reduced, and the air intake and foaming ratio of the liquid are effectively controlled, so that the air in the liquid can be fully circulated and refined, improving the uniformity of foam quality distribution.
