Description

Technical Field

[0001] The present invention relates to the technical field of food processing appliances, and particularly relates to a flow guide member and a frother. Background Art

[0002] In the technical field of food processing appliances, a rotary frother stirs a liquid (such as milk liquid, soybean liquid, fruit juice, etc.) through its own rotational movement, so that the liquid is mixed with air, and then foam is formed to achieve the purpose of enriching the taste. However, when the existing rotary frother is applied, due to reasons such as the user's operation method, it is often difficult to control the air intake amount and the fineness of the foam during the frothing process of the frother, resulting in differences in the quality of the foam (such as thickness, fineness, etc.) generated by each frothing operation of the frother, and it is difficult to maintain stability.

[0003] Specifically, in the prior art, the rotary frother cannot effectively separate and control the air intake process and the frothing process (the process of converting the inhaled air into fine foam). These two processes often occur simultaneously when the rotary frother works. That is to say, while frothing the liquid, new air enters the liquid, making it difficult to control the ratio of the air intake amount and the frothing of the liquid. Some air is not fully circulated and refined, and new gas is inhaled into the liquid and mixed with it, resulting in uneven and uncontrollable quality distribution of the foam frothed by the rotary frother. In this way, relatively rough foam will appear, affecting the overall quality of the foam. At the same time, the liquid will generate a vortex under the drive of the rotary frother, and the formation of the vortex will increase the contact area between the air and the liquid, and it is difficult to control the air being involved in the channel of the frother, thereby interfering with the controllability of the liquid air intake and affecting the stability of the air intake amount.

[0004] Therefore, how to effectively control the frothing air intake amount and the formation of the vortex of the frother to improve the foam quality is a problem to be solved by those skilled in the art. Summary of the Invention

[0005] Embodiments of the present invention provide a flow guide member and a frother, aiming to overcome the problems existing in the prior art.

[0006] The present invention provides a flow guide member applied to a frother, including:

[0007] A funnel-shaped fan blade is arranged above the rotary whipping head of the frother. The central axis of the funnel-shaped fan blade coincides with the rotation axis of the rotary whipping head. The funnel-shaped fan blade includes not less than 1 sub-fan blade;

[0008] A deceleration baffle is formed by vertically extending downward along the edge of the sub-fan blade and is arranged outside the rotary whipping head. The surface of the deceleration baffle faces the rotation direction of the rotary whipping head.

[0009] As an implementation manner, the curved surface of the sub - fan blade spirally extends outward along the rotation direction from the bottom to the top.

[0010] As an implementation manner, the deceleration baffle is of a concave arc structure.

[0011] The present invention also provides a foamer, including a flow - guiding member as described in any one of the above;

[0013] Alternatively, the foamer further includes a foaming cup, and the rotary whipping head is rotatably installed at the middle position of the bottom of the foaming cup.

[0014] As an implementation manner, a hollow installation sleeve rod extends upwardly from the inner side of the sub - fan blade. The funnel - shaped fan blade is sleeved on the rotary rod through the installation sleeve rod and fixedly installed in the installation hole at the lower end of the handheld part.

[0015] As an implementation manner, an installation gap is formed by cutting the side of the installation sleeve rod, and the width of the installation gap is greater than the width of the rotary rod.

[0016] As an implementation manner, a clamping part is arranged at the upper end of the installation sleeve rod. There is a clamping groove inside the installation hole whose shape matches that of the clamping part, and an open through - groove is arranged on the side of the clamping part.

[0017] As an implementation manner, a first fixing rod extending upward is arranged in the middle of the foaming cup. The rotary whipping head is sleeved on the first fixing rod, and a rotation - stopping key is arranged at the top of the first fixing rod;

[0018] A first installation cap extends upwardly from the inner side of the sub - fan blade. The bottom of the first installation cap is concavely arranged with a rotation - stopping groove for cooperating with the rotation - stopping key.

[0019] As an implementation manner, a second fixing rod extending upward is arranged in the middle of the foaming cup. The rotary whipping head is sleeved on the second fixing rod, and a thread is arranged on the top surface of the second fixing rod;

[0020] A second installation cap extends upwardly from the inner side of the sub - fan blade. The bottom of the second installation cap is concavely arranged with a thread groove for cooperating with the thread.

[0021] As an implementation manner, the foamer further includes an upper cover adapted to the foaming cup and an adjustment knob arranged in the middle of the top of the upper cover;

[0022] A non-circular anti-rotation through hole is provided in the middle of the upper cover. An elevating rod extends upward from the inner side of the sub-fan blade. The elevating rod is inserted into the anti-rotation through hole through an anti-rotation portion provided at the upper end. A vertical upward threaded rod is provided at the top of the anti-rotation portion. The adjusting knob is sleeved on the threaded rod through a threaded hole provided inside.

[0023] In the embodiment of the present invention, by arranging a funnel-shaped fan blade above the rotary whipping head of the bubbler, it can effectively guide the liquid flow, enabling the large bubbles generated by cotton beating to enter the rotary whipping head again for cyclic refinement, thereby improving the foaming effect and ensuring that the foam is delicate and evenly distributed. Also, by arranging a deceleration baffle below the funnel-shaped fan blade to block the liquid flow, the rotation speed of the liquid is reduced, the formation of vortices is inhibited, the controllability of the liquid air intake is improved, the foaming effect is further optimized, and the stability of the foam quality is guaranteed.

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

[0050] Please refer to the following Figures 1 to 3 , a flow guide member provided by an embodiment of the present invention is applied to a foamer, and specifically includes:

[0051] A funnel-shaped fan blade 10 is arranged above the rotary whipping head 20 of the foamer. The central axis of the funnel-shaped fan blade 10 coincides with the rotation axis of the rotary whipping head 20. The funnel-shaped fan blade 10 includes no less than 1 sub-fan blade 11;

[0052] A deceleration baffle 30 is formed by vertically extending downward along the edge of the sub-fan blade 11 and is arranged outside the rotary whipping head 20. The surface of the deceleration baffle 30 faces the rotation direction of the rotary whipping head 20.

[0053] In this embodiment, by arranging the funnel-shaped fan blade 10 above the rotary whipping head 20 of the foamer, the liquid flow can be effectively guided. When the rotary whipping head 20 whips the liquid, under the action of centrifugal force, the liquid level of the central liquid drops, and the liquid level of the edge liquid rises. At this time, the surrounding liquid can quickly supplement from the top opening of the funnel-shaped fan blade 10 to form a stable liquid flow cycle, optimizing the foaming effect. In addition, the bubbles formed when whipping the liquid will also preferentially flow to the center of the funnel-shaped fan blade 10 through the top opening, so that the unrefined large bubbles can enter the rotary whipping head 20 again for cyclic refinement to form secondary foaming, thereby refining the large bubbles and improving the foaming effect to ensure that the foam is delicate and evenly distributed.

[0054] In this embodiment, a deceleration baffle 30 is also provided below the sub - fan blades 11 of the funnel - shaped fan blade 10 to block the flow of the liquid, thereby reducing the rotational speed of the liquid, suppressing the formation of vortices, enhancing the controllability of the liquid intake volume, further optimizing the foaming effect, and ensuring the stability of the foam quality. At the same time, it can also avoid the phenomenon that the rotating whipping head 20 is exposed to the air due to the vortex, ensure that the rotating whipping head 20 is in full contact with the liquid, and can more quickly supplement the liquid volume entering the rotating whipping head 20, thereby increasing the liquid flow rate participating in the cyclic cotton beating, and enhancing the foaming efficiency and cotton - beating effect.

[0055] In a specific embodiment, the number of the sub - fan blades 11 (it can be understood that the number of the deceleration baffles 30 corresponds to it) and the size of the diversion gap between the sub - fan blades 11 can be adjusted according to actual needs to ensure the best deceleration effect and diversion 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 spirally extends outward from the bottom to the top. Combining the feature that the top opening diameter of the funnel - shaped fan blade 10 is larger than the bottom opening diameter, it can not only expand the contact area between the fan blade surface and the liquid, but also enhance the liquid diversion effect, enabling the liquid when the rotating whipping head 20 rotates to flow more smoothly along the fan blade curved surface towards the center of the funnel - shaped fan blade 10 and then re - flow towards the rotating whipping head 20, thereby promoting the circulation and refinement of the liquid, and enhancing the foaming uniformity and foam stability.

[0057] In a specific embodiment, the edges of the top opening and the bottom opening of the funnel - shaped fan blade 10 can also be set to be flush, so that the liquid and bubbles can be more evenly guided through the curved surface of the funnel - shaped fan blade 10 and flow towards the center of the funnel - shaped fan blade 10 for cotton beating and refinement. Of course, in other specific embodiments, the edges of the top opening and the bottom opening of the funnel - shaped fan blade 10 may not be set to be flush, but may be set such that the edge height changes continuously along an arc (spiral).

[0058] In one embodiment, the deceleration baffle 30 is of a concave arc structure.

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

[0060] In a specific embodiment, it can be seen from the fact that the curved surface of the funnel-shaped fan blade 10 spirally extends outward from the bottom opening to the top opening that its sub-fan blades 11 spirally extend outward from bottom to top. On this basis, extending vertically downward from the arc-shaped trailing edge of the sub-fan blade 11 can form a deceleration baffle 30 with a concave arc structure. Compared with the straight-plate-shaped deceleration baffle 30, the concave arc design can more effectively slow down the liquid flow rate, thereby suppressing the formation of vortices, ensuring smooth liquid flow, further optimizing the fineness and persistence of the foam, and enhancing the overall foaming effect.

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

[0062] In a specific application scenario, the funnel-shaped fan blade 10 and the deceleration baffle 30 can be integrally formed by using an injection molding process or other processes. This can simplify the production process, reduce the manufacturing cost, and at the same time enhance the structural strength, ensure the integrity and stability of the structure, and further improve the performance and durability of the foaming device.

[0063] In addition, the height and width of the deceleration baffle 30 can also be optimized according to the actual application scenario to further reduce the liquid rotation speed, ensure uniform distribution of the liquid in the foaming device, and avoid the problem of uneven foam caused by local over-fast flow, thereby comprehensively improving the foaming effect and foam stability.

[0064] The embodiment of the present invention also provides a foamer, including the above-mentioned flow guiding member. The foamer can drive the rotary whisking head 20 to whisk the liquid by setting a handheld part 40 to connect and drive it; or, it can also drive the rotary whisking head 20 to whisk the liquid by setting a foaming cup 50 to connect and drive it.

[0065] It can be understood that a driving device is built in the handheld part 40, and the output end of the driving device is connected to the rotating rod 21 and drives the rotating rod 21 to rotate. When the foamer is provided with the handheld part 40, the rotary whisking head 20 can be rotatably connected to the lower part of the handheld part 40 through the rotating rod 21, and the liquid intake volume during the whisking process can be adjusted by controlling the height of the rotary whisking head 20.

[0066] Specifically, in actual application scenarios, the generation of vortices makes it difficult to control the air intake of the bubbler. In the embodiments of the present invention, a deceleration baffle 30 is provided to suppress the generation of vortices and improve the control effect of the liquid air intake. 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 increased to weaken the deceleration effect of the deceleration baffle 30, and make the liquid more likely to form vortices, so that the rotary whipping head 20 can be close to the liquid level surface, increasing its contact area with the air, thereby stirring the liquid surface and the air to form a mixture to achieve air intake, and further promoting the formation of foam.

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

[0068] In a 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 is 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 through the mounting sleeve rod 12 and is fixed through the mounting hole at the lower end of the handheld part 40, so that the funnel-shaped fan blade 10 can be lifted and lowered synchronously with the rotary whipping head 20, thereby realizing more precise control of the cotton-beating process.

[0070] Specifically, an installation gap 13 can be formed by cutting on the side of the mounting sleeve rod 12, and the width of the installation gap 13 is set to be greater than the width of the rotating rod 21. After the rotary whipping head 20 is fixed to the lower part of the handheld part 40 through the rotating rod 21, the mounting sleeve rod 12 can be directly sleeved on the rotating rod 21 through the installation gap 13, improving the convenience and efficiency of installation. In some cases where the funnel-shaped fan blade 10 is not needed or needs to be replaced, the funnel-shaped fan blade 10 can be directly disassembled or installed on the rotating rod 21 by using the installation gap 13 of the mounting sleeve rod 12 without first removing the rotary whipping head 20, thus improving the user experience.

[0071] Of course, the installation gap 13 can also not be provided. Instead, a through hole penetrating in the vertical direction is provided in the center of the funnel-shaped fan blade 10. First, the funnel-shaped fan blade 10 is installed in the mounting hole at the lower end of the handheld part 40, and then the rotating rod 21 connecting the rotary whipping head 20 is passed through the through hole and the lower end of the handheld part 40 is fixed. After such a setting, when the funnel-shaped fan blade 10 needs to be disassembled, the rotary whipping head 20 needs to be removed first.

[0072] In another specific embodiment, a clamping portion 121 is provided at the upper end of the mounting sleeve rod 12, a clamping groove having a shape matching that of the clamping portion 121 is provided inside the mounting hole, and an open through groove 122 is provided on the side of the clamping portion 121. Thus, the stable connection between the funnel-shaped fan blade 10 and the hand-held portion 40 can be ensured by the cooperation between the clamping groove and the clamping portion 121, and the open through groove 122 provided on the side of the clamping portion 121 enables the clamping portion 121 to fine-tune its position when subjected to force, providing redundant installation space, facilitating the installation and removal of the funnel-shaped fan blade 10, improving the maintenance efficiency of the device, and facilitating the user to disassemble for cleaning and maintenance, thereby improving the user experience.

[0073] In specific application scenarios, the number and size of the open through-grooves 122 can be flexibly adjusted according to actual needs to meet the installation accuracy and maintenance convenience under different working conditions, and ensure the long-term stable operation of the device. For example, since the funnel-shaped fan blade 10 below the handheld portion 40 is hollow, the clamping portion 121 at its top also presents a cylindrical structure (or a circular ring structure), therefore, the number of open through-grooves 122 can be set to three, so that the clamping portion 121 is divided into three parts through the open through-grooves 122, and redundant installation space is provided by utilizing the segmentation design of the open through-grooves 122, so as to achieve segmented fine-tuning of the clamping portion 121, which is convenient for installation and disassembly.

[0074] Furthermore, a ring-shaped housing support ring 123 may be formed on the mounting sleeve rod 12 at the lower side of the clamping portion 121 to protrude outwards and extend to bear the weight of the hand-held portion 40 mounted on the mounting sleeve rod 12, thereby enhancing the stability of the overall structure. It is understandable that due to the presence of the open through slot 122, the housing support ring 123 also presents a segmented structure.

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

[0076] As mentioned above, the bubbler provided in the embodiment of the present invention may be provided with a handheld portion 40 or a bubble cup 50. Figure 4 As shown, when a foaming cup 50 is provided in the foamer, the rotating whipping head 20 can be rotatably installed in the middle position of the bottom of the foaming cup 50, and the rotating whipping head 20 can be driven by the foaming cup 50 to rotate and control the cotton beating process. It can also be understood that a driving device is built into the foaming cup 50 to connect and drive the rotating whipping head 20 to rotate.

[0077] Combination Figures 5 to 7As shown, in one embodiment, a first fixing rod 51 extending upward is provided in the middle of the foaming cup 50. The rotary whisking head 20 is sleeved on the first fixing rod 51, and a rotation prevention key 511 is provided at the top of the first fixing rod 51;

[0078] An inner side of the sub - fan blade 11 extends upward to be connected with a first mounting cap 14, and a rotation prevention groove for cooperating with the rotation prevention key 511 is concavely provided at the bottom of the first mounting cap 14.

[0079] In this embodiment, the rotary whisking head 20 rotates (the first fixing rod 51 does not move) while being sleeved on the first fixing rod 51. By using the cooperation between the rotation prevention key 511 provided at the top of the first fixing rod 51 and the rotation prevention groove at the bottom of the first mounting cap 14, the funnel - shaped fan blade 10 can be fixed on the first fixing rod 51. At this time, if you want to increase the air intake of the liquid, you can increase the rotation speed of the rotary whisking head 20, so that the rotation speed of the liquid increases and it is easier to form a vortex, thereby bringing more air into the liquid, thus increasing the air intake.

[0080] In a specific embodiment, the shapes of the rotation prevention key 511 and the rotation prevention groove are both non - circular. For example, a rotation prevention key 511 and a rotation prevention groove with a rectangular cross - section can be used. After the rotation prevention key 511 is inserted into the rotation prevention groove, it can no longer rotate, thereby fixing the funnel - shaped fan blade 10 on the first fixing rod 51 so that it will not rotate along with the rotation of the rotary whisking head 20 (if the funnel - shaped fan blade 10 is not fixed, the rotary whisking head 20 drives the liquid to rotate, and the liquid drives the funnel - shaped fan blade 10 to rotate).

[0081] Combined with 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 rotary whisking head 20 is sleeved on the second fixing rod 52, and a thread 521 is provided on the top surface of the second fixing rod 52;

[0082] An inner side of the sub - fan blade 11 extends upward to be connected with a second mounting cap 15, and a thread groove for cooperating with the thread 521 is concavely provided at the bottom of the second mounting cap 15.

[0083] In this embodiment, the rotary whisking head 20 rotates (the second fixing rod 52 does not move) while being sleeved on the second fixing rod 52. By the cooperation between the thread 521 of the second fixing rod 52 and the thread groove at the bottom of the second mounting cap 15, the height of the flow - guiding member can be adjusted by controlling the rotation direction of the rotary whisking head 20, thereby controlling the air intake of the liquid.

[0084] Specifically, when the rotary whisk head 20 is rotated clockwise, the liquid also rotates clockwise, driving the flow guide member to move upward along the thread 521 of the second fixing rod 52 until the flow guide member disengages from the thread 521. At this time, the flow guide member 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 volume.

[0085] After the air intake volume reaches the requirement, the whisk head 20 can be rotated counterclockwise, thereby changing the rotation direction of the liquid and driving the flow guide member to reverse. The flow guide member can re-engage with the thread 521 through the thread groove and move downward along the thread 521 until it reaches the bottom end of the thread 521. At this time, since the thread 521 has reached the bottom, the flow guide member can no longer rotate along the thread 521, and the flow guide member is effectively fixed on the second fixing rod 52 and stops rotating. In this way, the generation of the vortex can be suppressed by the deceleration baffle 30, and the liquid can be guided by the funnel-shaped fan blade 10 to precisely control the air intake volume, improve the cotton beating effect, and achieve the effect of improving the quality and stability of the foam.

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

[0087] In other embodiments, a smooth rotating shaft can also be extended and provided above the thread 521, and a limiting structure can be provided at the top of the rotating shaft. When set in this way, after the flow guide member disengages from the thread 521, it will continue to rotate around the rotating shaft, so that the deceleration baffle does not decelerate the liquid and can be restricted by the limiting structure and not leave the range of the second fixing rod 52. When reverse rotation is required for re-engagement, the flow guide member will first reverse around the smooth rotating shaft until the thread groove is aligned with the thread 521 again, and then move downward along the thread 521 to the fixed position, ensuring flexible and stable operation and further improving the control accuracy.

[0088] Combined with Figures 10 to 13 As shown in the figure, in another embodiment, the foamer further includes an upper cover 60 adapted to the foaming cup 50 and an adjustment knob 70 provided in the middle of the top of the upper cover 60;

[0089] A non-circular anti-rotation through hole 61 is provided in the middle of the upper cover 60. An elevating rod 16 extends upward from the inner side of the sub-fan blade 11. The elevating rod 16 is inserted into the anti-rotation through hole 61 through an anti-rotation portion 161 provided at the upper end. A vertical threaded rod 162 is provided at the top of the anti-rotation portion 161. The adjustment knob 70 is sleeved on the threaded rod 162 through a threaded hole provided inside.

[0090] In this embodiment, an upper cover 60 with a rotation prevention through hole 61 can also be arranged above the foaming cup 50, and a lifting rod 16 with a rotation prevention portion 161 is arranged in the flow guiding member. The lifting rod 16 is inserted into the rotation prevention through hole 61 through the rotation prevention portion 161, and a threaded rod 162 is arranged at the top of the rotation prevention portion 161, and the adjustment knob 70 is sleeved on the threaded rod 162.

[0091] On this basis, when the rotating whipping head 20 rotates, the flow guiding member cannot rotate along with the rotating whipping head 20 due to the limitation of the rotation prevention portion 161. Thus, the generation of vortices can be inhibited by the deceleration baffle 30, and the liquid can be guided by the funnel-shaped fan blade 10.

[0092] When the air intake needs to be increased, the adjustment knob 70 can be rotated to make the screw hole of the adjustment knob 70 and the threaded rod 162 rotate relative to each other, and the length of the mutual engagement is increased. Since the lifting rod 16 cannot rotate, at this time, the lifting rod 16 will be dragged upward along the rotation prevention through hole 61 by the screw hole (thread) under the action of the reaction force, and thus drive the flow guiding member to rise, thereby weakening the inhibitory effect of the deceleration baffle 30 on the vortices and increasing the liquid air intake brought by the vortices.

[0093] When the air intake reaches the required amount, rotating the adjustment knob 70 in the reverse direction can make the lifting rod 16 move reversely (descend) in the rotation prevention through hole 61 until it descends to the required position of the flow guiding member, so as to re-use the deceleration baffle 30 to inhibit the formation of vortices. Thus, the controllability of the liquid air intake is improved, the foaming effect is further optimized, and the stability of the foam quality is ensured.

[0094] Further, in a specific embodiment, a third fixing rod extending upward can also be arranged in the middle of the foaming cup 50, and a mounting groove matching with the third fixing rod is arranged at the bottom of the lifting rod 16 to ensure that the lifting rod 16 always remains stable during the rising or falling process.

[0095] The embodiment of the present invention can realize the effective separation control of the liquid air intake process and the cotton beating process by controlling the flow guiding member, avoid the conflict between the two working processes, intake air only when needed, reduce the new air intake while beating the liquid, and effectively control the ratio of the liquid air intake and the cotton beating, so that the air in the liquid can be fully circulated and refined, and the uniformity of the foam quality distribution is improved.
