[0037] Please also read Figures 1 to 9 The hand-held stirring device for rapid foaming provided by the utility model is now described. The hand-held stirring device for rapid foaming comprises a main unit 10, a secondary reduction box 20 and a plurality of foaming rods 30. The main unit 10 has a driving shaft 11; the secondary reduction box 20 comprises a sun gear 21 fixedly connected to the driving shaft 11, a plurality of first planetary gears 22 meshing with the sun gear 21, a planetary frame 23 connected to the plurality of first planetary gears 22, a reduction gear 24 arranged on the planetary frame 23, and a plurality of second planetary gears 25 drivingly connected to the reduction gear 24; the plurality of foaming rods 30 are fixedly connected to the plurality of second planetary gears 25 in a one-to-one correspondence, and the plurality of foaming rods 30 have different lengths.

[0038] Specifically, the lengths of the plurality of bubble rods 30 are different, which includes all different and partially different. That is, if the lengths of every two bubble rods 30 among the five bubble rods 30 are different, then they are all different; if the length of only one bubble rod 30 among the five bubble rods 30 is different, and the lengths of the remaining four bubble rods 30 are the same, then they are partially different.

[0039] It is easy to understand that a stirring head is provided at the free end of the foaming rod 30 , and the shape of the stirring head is the same as several common stirring heads on the market, which will not be described in detail here.

[0040] It should be noted that a motor is installed inside the host 10, and the drive shaft 11 is the output shaft of the motor. The motor is powered by installing a battery inside the host 10, or installing a power cord and a plug on the host 10; and in order to facilitate the switching of the motor, a switch button 15 for controlling the motor switch can also be set on the host 10.

[0041] Compared with the prior art, the fast-foaming hand-held stirring device provided in the present embodiment has the following advantages: after the secondary reduction gearbox 20 is installed on the main unit 10, when the main unit 10 is turned on, the driving shaft 11 of the main unit 10 rotates to drive the sun gear 21 to rotate, the sun gear 21 rotates to drive the first planetary gears 22 to rotate and drive the planetary frame 23 to rotate, the planetary frame 23 rotates to drive the reduction gear 24 to rotate, the reduction gear 24 then drives the second planetary gears 25 connected thereto to rotate, each second planetary gear 25 drives a foaming rod 30 to rotate, and the foaming process of the food is realized. The fast-foaming hand-held stirring device of the utility model is provided with the first planetary gear 22, the reduction gear, the second planetary gear 25, etc., and can realize the output power of large torque after the reduction gear 24 is reduced, and then realize the stirring of food with large torque, and can obtain greater deceleration benefits than conventional stirrers; the food is stirred by the foaming rods 30 of different lengths, which can effectively increase the contact area of ​​foaming, shorten the operation time, and improve the user's operation experience.

[0042] In some embodiments, a specific matching method between the second planetary gear 25 and the reduction gear 24 can be as follows: Figures 1 to 7 See the structure shown. Figures 1 to 7 , the multiple second planetary gears 25 are directly meshed with the reduction gear 24 to achieve the same-direction rotation of the multiple frothing rods 30. That is, each second planetary gear 25 is directly meshed with the reduction gear 24, and the multiple second planetary gears 25 are independent of each other without any meshing relationship, so when the reduction gear 24 rotates, the multiple second planetary gears 25 can rotate clockwise or counterclockwise at the same time, that is, the multiple frothing rods 30 can rotate in the same direction.

[0043] In some embodiments, a modified matching mode between the second planetary gear 25 and the reduction gear 24 can be as follows: Figure 8 See the structure shown. Figure 8, a coaxial transmission gear 26 is provided on one of the second planetary gears 25, the transmission gear 26 meshes with the reduction gear 24, and the plurality of second planetary gears 25 mesh with each other. That is, the plurality of second planetary gears 25 are indirectly connected to the reduction gear 24 through transmission, and are directly meshed with the reduction gear 24 through a transmission gear 26, so that when the reduction gear 24 rotates, one of the second planetary gears 25 can be driven to rotate, and the second planetary gear 25 drives the second planetary gear 25 meshed with it to rotate, thereby realizing the reverse rotation of the foaming rods 30 on the two meshed planetary gears.

[0044] The two matching modes of the second planetary gear 25 and the reduction gear 24 can realize the same-direction or reverse rotation of the foaming rod 30. According to different stirring requirements, the same-direction rotation or reverse rotation can generate different stirring vortices for different ingredients, achieving different stirring effects.

[0045] In some embodiments, an improved implementation of the above-mentioned two-stage reduction gearbox 20 can be adopted as follows Figures 3 to 6 See the structure shown. Figures 3 to 6 The secondary reduction box 20 further includes a housing 27, on which a gear ring 28 is fixedly connected. The gear ring 28 is sleeved on the outer periphery of the plurality of first planetary gears 22 and meshes with the plurality of first planetary gears 22 respectively. The bottom of the housing 27 has a through hole for the foaming rod 30 to extend out. The housing 27 accommodates the sun gear 21, the first planetary gear 22, the planet carrier 23, the reduction gear 24 and the second planetary gear 25, which not only plays an aesthetic role, but also the gear ring 28 is fixed on the housing 27 to limit the outer periphery of the plurality of first planetary gears 22, so that the first planetary gears 22 rotate around the sun gear 21, ensuring stable transmission between them; the housing 27 can also prevent impurities from entering between the teeth and affecting the meshing.

[0046] In some embodiments, a specific matching method between the housing 27 and the host 10 can be as follows: Figures 3 to 6 See the structure shown. Figures 3 to 6 A first groove 271 is provided at the top of the housing 27, and a transmission shaft 211 located in the first groove 271 is fixedly connected to the sun gear 21; a protrusion 12 detachably connected to the first groove 271 is provided at the bottom of the main engine 10, and a second groove 13 is provided at the center of the protrusion 12 for the transmission shaft 211 to extend into and cooperate with the drive shaft 11.

[0047] When installing the secondary reduction box 20, the transmission shaft 211 is extended into the second groove 13, and the protrusion 12 is extended into the first groove 271. After the protrusion 12 is connected to the first groove 271, the connection between the secondary reduction box 20 and the main unit 10 can be realized. When the main unit 10 is started, the foaming rod 30 can be driven to rotate.

[0048] Optionally, the first groove 271 and the protrusion 12 can be detachably connected by means of threaded connection, snap connection, etc.

[0049] In some embodiments, a specific matching method between the first groove 271 and the protrusion 12 can be as follows: Figure 3 to Figure 4 See the structure shown. Figure 3 to Figure 4 The side wall of the first groove 271 is provided with a convex strip 272, and the outer periphery of the protrusion 12 is provided with a hook 14 that can reciprocate along its own radial direction, and the hook 14 is used to be hooked at the bottom of the convex strip 272. The hook 14 protrudes from the outer periphery of the protrusion 12, and can be retracted into the protrusion 12 in the process of axial movement close to the protrusion 12. When the shell 27 and the host 10 need to be assembled, the hook 14 is moved to a state where it does not extend out of the outer periphery of the protrusion 12, and then the protrusion 12 is inserted into the first groove 271, and the hook 14 is moved to a state where it extends out of the outer periphery of the protrusion 12 and can be hooked at the bottom of the convex strip 272. At this time, the matching of the host 10 and the shell 27 is completed, and the matching of the drive shaft 11 and the transmission shaft 211 is also completed at the same time.

[0050] In some embodiments, a specific arrangement of the hook 14 on the protrusion 12 may be as follows: Figures 3 to 6 See the structure shown. Figures 3 to 6 The protrusion 12 is provided with a button 15 that slides along its radial direction. A spring is provided inside the protrusion 12 to make the button 15 extend out of the outer peripheral surface of the protrusion 12. The button 15 is fixedly connected to the hook 14. The button 15 is used to drive the hook 14 to reciprocate along the radial direction of the protrusion 12. The protrusion 12 and the first groove 271 can be plugged in by pressing the button 15 to drive the hook 14 to retract into the protrusion 12. After releasing the button 15, the spring rebounds, so that the button 15 drives the hook 14 to extend out of the outer peripheral surface of the protrusion 12 and just get stuck at the bottom of the convex strip 272, completing the matching between the host 10 and the housing 27. The structure is simple, the cost is low, and the operation is convenient.

[0051] In the specific implementation, see Figure 6 A connecting rod 16 is provided on the side of the button 15 facing the axis of the protrusion 12, and a guide sleeve 17 is provided in the protrusion 12 to slide with the connecting rod 16. The spring is arranged in the guide sleeve 17, which can not only stabilize the pressing and rebounding process of the button 15, but also guide the compression and rebound process of the spring through the guide sleeve 17.

[0052] As a modified implementation method for controlling the reciprocating movement of the hook 14, a control button can be set on the periphery of the main unit 10, and a cylinder for driving the reciprocating movement of the hook 14 can be set inside the protrusion 12. The control button is used to control the extension and retraction of the piston rod on the cylinder to achieve radial reciprocating movement of the hook 14 along the protrusion 12.

[0053] In some embodiments, an improved implementation of the above-mentioned two-stage reduction gearbox 20 can be adopted as follows Figures 3 to 7 See the structure shown. Figures 3 to 7 A mounting plate 29 is fixed at the bottom of the gear ring 28. A plurality of limiting sleeves 291 are arranged at the bottom of the mounting plate 29. The limiting sleeves 291 correspond to the plurality of second planetary gears 25 one by one and are rotatably matched. The limiting sleeves 291 are arranged on the mounting plate 29. The limiting sleeves 291 are sleeved on the outer periphery of the second planetary gears 25 and are rotatably matched with the second planetary gears 25. The limiting sleeves 291 improve the rotation stability of the second planetary gears 25, thereby improving the rotation stability of the foaming rod 30, and preventing the foaming rod 30 from shaking during rotation and causing food to splash.

[0054] In some embodiments, a specific matching method between the foaming rod 30 and the second planetary gear 25 can be as follows: Fig. 9 See the structure shown. Fig. 9 The end of the foaming rod 30 is provided with a plug connector 31, a slot 32 is provided on the plug connector 31, and a guide bevel 33 is provided on the upper side of the slot 32 and the top of the plug connector 31; the center of the second planetary gear 25 has a middle hole plugged with the foaming rod 30, and the inner wall of the middle hole is protruding with a clamping part 251 that matches the slot 32, and there are multiple clamping parts 251 distributed around the axial interval of the middle hole. When the foaming rod 30 is inserted into the middle hole, the clamping part 251 first contacts the guide bevel 33 at the top of the plug connector 31, and then enters the slot 32 through the guide bevel 33 on the upper side of the slot 32 and is located in the slot 32. This structure facilitates the installation and replacement of the foaming rod 30, and then the user can replace the foaming rod 30 of different shapes according to different stirring needs, which is more flexible to use.

[0055] In some embodiments, an improved matching method between the foaming rod 30 and the second planetary gear 25 can be as follows: Fig. 9 See the structure shown. Fig. 9 A plurality of protruding ribs 252 are also provided in the middle hole, and the ribs 252 correspond to the plurality of clamping parts 251 one by one. A limiting plate 34 is also provided on the periphery of the bubble rod 30, and the limiting plate 34 is used to be inserted into the interval between any two ribs 252. After the bubble rod 30 is installed, the limiting plate 34 is inserted into the space between any two ribs 252, which can limit the bubble rod 30 in the circumferential direction and prevent the bubble rod 30 from rotating when working.

[0056] Specifically, one or more limiting plates 34 may be provided on the outer periphery of the bubble rod 30 . When a plurality of limiting plates 34 are provided, the plurality of limiting plates 34 are evenly distributed on the outer periphery of the bubble rod 30 .

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
