[0032] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1-7 As shown, this utility model protects a handheld mixer, and the handheld mixer includes a handle 3 and a whipping head. The whipping head has the following structure: First, the mixer whipping head includes a connecting rod 1 and a connecting ring 21, and one end of the connecting rod 1 is used to connect to the handle 3 of the handheld mixer.

[0034] Meanwhile, the connecting ring 21 has at least one reinforcing rib and a connecting part 22 for connecting with the connecting rod 1, and a hair-spraying net 4 is provided between the inner wall of the connecting ring 21 and the connecting part 22, and the reinforcing rib 23 is located on the side of the hair-spraying net 4 away from the connecting rod 1.

[0035] Therefore, in actual use, the hair-spraying net 4 is used to achieve hair-spraying. Compared with a spring, the hair-spraying net 4 is easier to clean, and the reinforcing ribs 23 can improve strength and thus extend service life. The number of reinforcing ribs 23 can be selected according to actual needs, and three are shown in the attached diagram.

[0036] Furthermore, in order to facilitate processing and installation and reduce the installation gap between components, the reinforcing rib 23, the connecting part 22 and the connecting ring 21 can be made as an integral molding, or the reinforcing rib 23, the connecting part 22, the connecting ring 21 and the hairnet 4 can be designed as injection molding, that is, secondary injection molding.

[0037] Therefore, in actual use, the one-piece molding and / or injection molding facilitates processing and installation, and reduces the installation gap between parts, which in turn reduces cleaning dead corners and makes cleaning easier.

[0038] Secondly, the hair-spraying net 4 is positioned at 1 / 4 to 2 / 3 of the height of the connecting ring 21, more preferably at 1 / 4 to 1 / 2 of the height. This positions the hair-spraying net 4 closer to the lower surface of the connecting ring 21 (the surface furthest from the connecting rod 1), i.e. Figure 7 The image shows the whisk being closer to the bottom of the cup, resulting in a larger space between the whisk 4 and the upper surface of the connecting ring 21. Therefore, during whisking, the liquid, under the influence of centrifugal force and gravity, moves in the following order: Figure 7 The motion path shown interacts with the whipping head, and a larger space (referring to the space between the whipping net 4 and the upper surface of the connecting ring 21) can better catch the gradually falling liquid, allowing the liquid to come into more full contact with the whipping net 4 for whipping, thus improving the efficiency and smoothness of whipping. Conversely, a smaller space will cause the liquid to flow repeatedly without being whipped by the whipping net 4, resulting in larger bubbles and thus ruining the whipped texture.

[0039] Meanwhile, the height of the connecting ring 21 is greater than or equal to 5mm, for example, 8-10mm. Therefore, after the whipping head is immersed in the liquid, the higher the connecting ring 21 is, the larger the contact area between the connecting ring 21 and the liquid. Compared to the working state of the whipping net 4 alone (i.e., without the connecting ring 21) rotating independently, the setting of the connecting ring 21 can make the vortex generated by the liquid during whipping larger, thereby increasing the flow rate and shortening the whipping time.

[0040] like Figures 1-6 As shown, the structure of the reinforcing rib 23 is diverse, and can be as follows: Figure 3 As shown, the reinforcing rib 23 is a long strip located between the inner wall of the connecting ring 21 and the connecting part 22. The side of the reinforcing rib 23 away from the hair-spraying net 4 is curved, and the height of the reinforcing rib 23 gradually increases along the direction close to the connecting part 22.

[0041] Therefore, in actual use, the curved surface serves to guide and direct the flow of liquid, allowing the liquid remaining on the whipping head to fall off along the curved surface when the whipping head stops rotating.

[0042] It can also be like Figure 5 As shown, the reinforcing rib 23 is V-shaped and includes reinforcing strip 1 231 and reinforcing strip 232. The connection between reinforcing strip 1 231 and reinforcing strip 232 is with the connecting part 22, and the other end of reinforcing strip 1 231 and reinforcing strip 232 is with the inner wall of the connecting ring 21. Moreover, the side of reinforcing strip 1 231 and reinforcing strip 232 away from the hair-spraying net 4 is a slope, and the height of the reinforcing rib 23 gradually increases along the direction close to the connecting part 22.

[0043] Therefore, in actual use, the V-shaped design can further improve strength and service life, and the inclined surface can guide and drain the liquid, allowing the liquid remaining on the whipping head to fall off along the inclined surface when the whipping head stops rotating.

[0044] like Figures 1-5 As shown, the structure of the connecting part 22 is as follows: First, the height of the end of the connecting part 22 away from the connecting rod 1 is higher than the height of the lower surface of the connecting ring 21, and the outer surface of the connecting part 22 at this end is an arc surface.

[0045] Therefore, in actual use, by adjusting the height, the connecting part 22 contacts the bottom of the cup, thereby reducing the contact between the lower surface of the connecting ring 21 (i.e., the side away from the connecting rod 1) and the bottom of the cup. Furthermore, the curved surface reduces friction, thus not affecting the normal use of the whipping head, providing a margin of error for less experienced operators. Simultaneously, the curved surface reduces fluid resistance during whipping, thus aiding in the frothing of the liquid.

[0046] Meanwhile, the connecting part 22 has a connecting groove 221 near one end of the connecting rod 1, and the inner wall of the connecting groove 221 has two flat surfaces formed on both sides. The end of the connecting rod 1 is located inside the connecting groove 221, and the outer side of the end of the connecting rod 1 has a flat surface formed on the corresponding flat surface.

[0047] Therefore, in actual use, the connection is achieved by the end of the connecting rod 1 being located in the connecting groove 221, and the relative rotation between the connecting part 22 and the connecting rod 1 is restricted by the planar arrangement.

[0048] like Figures 1-6 As shown, the whipping head is detachably mounted on the handle 3. The specific structure is as follows: First, the end of the connecting rod 1 that is connected to the handle 3 is provided with a mounting part 7, and the mounting part 7 has a card interface 71 that is compatible with the handle 3.

[0049] Meanwhile, the corresponding handle 3 has the following structure: First, the handle 3 has a built-in motor 5, and one end of the motor 5 is provided with a drive shaft 51, which passes through the handle 3 and protrudes. Moreover, the protruding end of the drive shaft 51 is fitted with a connector 6, and the outer side of the connector 6 is provided with a buckle 61.

[0050] Therefore, in actual use, the whipping head is installed by fitting the mounting part 7 onto the outside of the connector 6 and placing the buckle 61 inside the card interface 71. When disassembling, it can be pulled outwards. Thus, the whipping head is detachably mounted on the handle 3, allowing for easy disassembly and cleaning, thereby reducing the contact between the handle 3 and water, and also facilitating the replacement of the whipping head.

[0051] Furthermore, a protruding plate is provided on the outer side of the mounting component 7, and the protruding plate is inclined, meaning that the height of the end of the protruding plate near the mounting component 7 is lower than the height of the end of the protruding plate away from the mounting component 7. Therefore, in actual use, the protruding plate can play a role in flow restriction, that is, restricting the flow of liquid to the handle 3, thereby protecting the handle 3. Moreover, the protruding plate is inclined, that is, the structure is higher on the outside and lower on the inside, so that the liquid flows inward rather than outward and flows to the handle 3, thereby further restricting the flow of liquid to the handle 3.

[0052] Meanwhile, the specific structure of the mounting component 7 is as follows: First, a channel is opened in the middle of the mounting component 7, and a protruding strip is provided on the inner wall of the channel. Furthermore, a locking interface 71 is opened on the outer side of the mounting component 7 below the protruding strip. Therefore, in actual use, the end of the whipping head connected to the handle 3 is located inside the channel and on the protruding strip. The connection between the whipping head and the mounting component 7 is injection molded, while the connector 6 of the handle 3 is located inside the channel and below the protruding strip.

[0053] like Figure 2 and Figure 6 As shown, the handle 3 contains a motor 5 and a circuit board 8. The motor 5 is connected to the whipping head and electrically connected to the circuit board 8. Therefore, in actual use, the motor 5 will drive the whipping head to rotate after receiving the information sent by the circuit board 8.

[0054] Meanwhile, the circuit board 8 is provided with contacts 81, and the handle 3 is provided with a pusher 9 corresponding to the contacts 81. The pusher 9 includes a push plate 91 and a push part 92 provided at the bottom of the push plate 91. By pushing the pusher 9, the push part 92 makes contact with the contacts 81, thereby sending information to the circuit board 8, that is, instructing the circuit board 8 to drive the motor 5. There are two push parts 92, and the contacts 51 are located between the two.

[0055] Secondly, the other structural features of the pusher 9 are as follows: Firstly, two connecting plates 93 are symmetrically arranged at the bottom of the push plate 91, and a locking block 931 is provided at the end of the connecting plate 93 away from the push plate 91. Therefore, in actual use, the end of the connecting plate 93 away from the push plate 91 passes through the handle 3 and is located inside the handle 3, and the locking block 931 abuts against the inner wall of the handle 3 to prevent the pusher 9 from detaching from the handle 3. Furthermore, for sealing purposes, a sealing ring is provided between the push plate 91 and the outer side of the handle 3.

[0056] Furthermore, the handle 3 has a storage slot for placing the push plate 91 and allowing the push plate 91 to move, and the handle 3 has an elongated hole for the connecting plate 92 to pass through and move, and the handle 3 has a groove for placing the sealing ring.

[0057] At the same time, the top of the push plate 91 has a slot to make it easy to insert a finger, and the slot has a protrusion to increase friction and make it easier to push.

[0058] like Figure 2 and Figure 6 As shown, the handle 3 also has a built-in power supply 10, which is used to provide power to the motor 5. The handle 3 includes a housing 31 and upper and lower cover plates. The upper and lower cover plates are located inside the housing 31 and are provided with a seal between them. The lower cover plate is also provided with a cover and a charging port on its outer side, and the cover is used to protect the charging port.

[0059] Meanwhile, the drive shaft 51 passes through the upper cover plate and is exposed. The upper cover plate has a slot, so that the exposed end of the drive shaft 51 and the connecting piece 6 are mostly located in the slot, which can play a protective role. In addition, a sealing ring is provided between the push plate 91 and the housing 31, and the locking block 931 abuts against the inner wall of the housing 31.

[0060] Furthermore, the outer shell 31 also houses the inner shell 32, which better protects the internal structure.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
