Description

Technical Field

[0001] This utility model relates to the field of handheld mixer technology, and specifically to a whisking head for a handheld mixer and a handheld mixer. Background Technology

[0002] A handheld mixer is a portable kitchen appliance primarily used for mixing, stirring, and whipping various ingredients. Its structure includes a handle and a mixing head, which rotates under the drive of a motor, allowing for adjustments to mixing needs by varying motor speeds. There are various types of mixing heads, one of which is a whipping head. This whipping head consists of a connecting rod and a spring at the end of the connecting rod, with the spring and connecting rod fixedly connected (not detachable). Therefore, the entire whipping head must be cleaned, which can leave some hard-to-reach areas uncleaned. Furthermore, the spring is relatively more prone to damage, but because it's a fixed connection, once the spring fails, the entire whipping head must be replaced. The connecting rod can still be used, making replacing the entire whipping head somewhat wasteful.

[0003] With the development of technology, detachable springs have been developed, in which the spring can be detachably mounted on the mounting plate. However, the mounting plate itself does not have holes, so the liquid cannot flow through the middle but must flow around the mounting plate. Therefore, the mounting plate itself will obstruct the flow of fluid, thus hindering the whipping process and affecting the whipping effect. Summary of the Invention

[0004] The purpose of this invention is to provide a whipping head for a handheld mixer and a handheld mixer. Because the spring itself is elastic, it can be removed by pulling, meaning the spring is detachable. Therefore, it can be cleaned separately for a more thorough cleaning, and the spring can be replaced individually if it is damaged. At the same time, the design of the drainage hole allows the liquid to pass directly through the mounting plate, and the passing liquid can form annular vortices in the up-down and in-outward directions, which facilitates the flow of the liquid and is beneficial for whipping, thus improving the whipping effect. Therefore, it solves the problems of non-removable springs and the problems of detachable springs where the placed parts would obstruct the flow of liquid.

[0005] The purpose of this utility model is achieved as follows:

[0006] A whipping head for a handheld mixer includes a spring, a connecting rod, and a mounting plate, wherein one end of the connecting rod is connected to the handle of the handheld mixer, and the other end of the connecting rod is connected to the mounting plate;

[0007] The mounting plate has a mounting groove on its outer side, and the mounting plate has at least one drainage hole for connecting the upper and lower surfaces. A spring is sleeved on the outer side of the mounting plate and located in the mounting groove.

[0008] Preferably, the mounting plate has a protrusion on the side away from the connecting rod, and the outer surface of the protrusion is arc-shaped. An inclined surface is provided between the protrusion and the mounting plate, and the inclined surface has the drainage hole.

[0009] Preferably, the mounting plate has a groove on the side near the connecting rod, and the groove communicates with the drainage hole.

[0010] Preferably, the end of the connecting rod that connects to the handle is provided with a mounting component, and the mounting component has a snap-fit ​​interface that is compatible with the handle.

[0011] Preferably, a protruding plate is provided on the outer side of the mounting component, and the height of the protruding plate near the mounting component is lower than the height of the protruding plate away from the mounting component.

[0012] Preferably, the mounting component has a channel in the middle, and the inner wall of the channel is provided with a protrusion. The mounting component has a card interface below the protrusion on the outer side, and the end of the connecting rod connected to the handle is located in the channel and abuts against the protrusion.

[0013] A hand mixer, including a handle and a whipping head as described in any of the above.

[0014] Preferably, a support is mounted on the handle, and the support includes a kit and a support plate, wherein the kit is used to be mounted on the outside of the handle, and the top of the support plate is connected to the kit.

[0015] Preferably, the whipping head is detachably mounted on the handle, and the handle has a built-in motor, with a drive shaft at one end of the motor, and the drive shaft passes through the handle and protrudes outwards.

[0016] The drive shaft has a connector sleeved on one exposed end, and a buckle is provided on the outside of the connector. The end of the connecting rod that connects to the handle is provided with an installation part, and the installation part is sleeved on the outside of the connector and has a corresponding buckle interface.

[0017] Preferably, the handle has a built-in motor and circuit board, and the motor is connected to the whipping head and electrically connected to the circuit board;

[0018] The circuit board is provided with contacts, and the handle is provided with a pusher corresponding to the contacts. The pusher includes a push plate and a push part provided at the bottom of the push plate. The pusher is pushed so that the push part contacts the contacts.

[0019] Two connecting plates are symmetrically arranged at the bottom of the push plate, and a locking block is provided at the end of the connecting plate away from the push plate. The end of the connecting plate away from the push plate passes through the handle and is located inside the handle, and the locking block abuts against the inner wall of the handle to prevent the pusher from detaching from the handle.

[0020] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0021] Because the spring itself is elastic, it can be removed by pulling, meaning the spring is detachable. This allows for separate cleaning, resulting in a more thorough cleaning, and the spring can be replaced individually if damaged. Furthermore, the drainage holes allow liquid to flow directly through the mounting plate, forming annular vortices in both vertical and horizontal directions. This facilitates liquid flow and promotes better frothing, leading to improved frothing results. Attached Figure Description

[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1-8 As shown, this utility model protects a handheld mixer, which includes a handle 2 and a whipping head. The whipping head has the following structure: it includes a spring 31, a connecting rod 32 and a mounting plate 33. One end of the connecting rod 32 is used to connect to the handle 2 of the handheld mixer, and the other end of the connecting rod 32 is connected to the mounting plate 33.

[0038] Meanwhile, a mounting groove 331 is provided on the outer side of the mounting plate 33, and the mounting plate 33 has at least one drainage hole 332 for connecting the upper and lower surfaces, and the spring 31 is sleeved on the outer side of the mounting plate 33 and located in the mounting groove 331. The spring 31 can be annular or other shapes.

[0039] Therefore, in actual use, since the spring 31 itself is elastic, it can be removed by pulling. Specifically, the spring 31 is pulled outward to make the opening enclosed by the spring 31 larger, so the spring 31 can be removed from the mounting plate 33. Therefore, the spring 31 is detachable, so it can be cleaned separately, thus cleaning it more thoroughly. And if the spring is damaged, it can be replaced separately.

[0040] Furthermore, the drainage holes 332 allow liquid to pass directly through the mounting plate 33 and flow from its upper surface to its lower surface. During this flow, annular vortices are formed in the vertical and horizontal directions, facilitating liquid exchange and promoting rapid mixing of liquid with air for initial agitation. This provides an initial agitation for the liquid that will be agitated further by the spring 31, resulting in better agitation. Multiple drainage holes 332 can be provided to further facilitate liquid flow.

[0041] Meanwhile, the drainage hole 332 can also prevent liquid residue and facilitate cleaning. Therefore, after the liquid is agitated, the agitator head is removed from the liquid. The liquid on the mounting plate 33 will pass through the drainage hole 332 and converge into the liquid below, thus preventing liquid from remaining on the mounting plate 33. Moreover, when cleaning the agitator head, the water flow can impact the inside of the mounting plate 33 and flow out from the drainage hole 332, thereby improving cleaning efficiency and reducing the possibility of liquid or bacteria accumulating on the mounting plate 33.

[0042] like Figures 1-6As shown, a protrusion 333 is provided on the side of the mounting plate 33 away from the connecting rod 32, and the outer surface of the protrusion 333 is arc-shaped. An inclined surface is provided between the protrusion 333 and the mounting plate 33, and the inclined surface has the drainage hole 332. Therefore, in actual use, the protrusion 333 contacts the bottom of the cup, thereby reducing the contact between the upper surface of the mounting plate 33 (i.e., the side away from the connecting rod 32) and the bottom of the cup. Specifically, when whipping liquids, the general professional whipping technique involves suspending the whipping head in the liquid and continuously adjusting its position, i.e., to the center or off-center position, to achieve whipping. Due to the varying heights of containers, inexperienced operators may accidentally contact the bottom of the container with the whipping head. However, the protrusion 333 of this invention, being arc-shaped, has low friction and does not affect the normal use of the whipping head, providing a tolerance for errors by less experienced operators.

[0043] Meanwhile, the arc shape reduces resistance to the fluid during the frothing process, thus aiding in the frothing of the liquid. Furthermore, the inclined surface acts as a guide, and the portion connecting the outer surface of the protrusion 333 to the mounting plate 33 can be configured to connect with the inner wall of the drainage hole 332, resulting in better drainage.

[0044] Secondly, a groove 334 is provided on the side of the mounting plate 33 near the connecting rod 32, and the groove 334 is connected to the drainage hole 332. Therefore, in actual use, the groove 334 is used to collect the liquid passing through the drainage hole 332 and then merge it with the liquid located on the lower surface of the mounting plate 33.

[0045] like Figures 1-2 As shown, a support is installed on the handle 2, and the support includes a kit 11 and a support plate 12. The kit 11 is used to install on the outside of the handle 2, and the top of the support plate 12 is connected to the kit 11. The bottom of the support plate 12 abuts against the item being placed and is used to place the handheld milk frother horizontally above the item being placed. The installation can be done by a sleeve, snap-fit, or adhesive method.

[0046] Therefore, in actual use, the handheld milk frother is placed horizontally above the item by the bottom of the support plate 12 abutting against it. Thus, both the handle 2 and the frothing head 3 are positioned above the item, with a distance between them and the item's upper surface. This prevents the handle 2 from rolling and the frothing head 3 from contacting the item when placed horizontally, thereby avoiding contamination and bacterial growth. Furthermore, the stable placement of the handheld milk frother allows the operator to free their hands for other tasks.

[0047] Meanwhile, the bottom of the support plate 12 is formed with a support surface 122, and the bottom of the support plate 12 is formed with a slope on the outside of the support surface 122. Therefore, in actual use, the support surface 122 abuts against the placed item, and the slope setting makes the bottom of the support plate 12 not completely fit with the placed item, which facilitates the separation of the support plate 12 from the placed item later.

[0048] Furthermore, the structure of the kit 11 is diverse; for example, the kit 11 can be ring-shaped. Alternatively, the kit 11 can be made of a flexible material, and an opening can be provided on the side of the kit 11 away from the support plate 12.

[0049] Therefore, in actual use, the opening design makes kit 11 more flexible and can be adapted to larger handheld milk frothers.

[0050] Secondly, a gap is provided between the kit 11 and the support plate 12, and they are connected by a connecting part. Therefore, in actual use, due to the gap, the kit can be engaged with the cup wall, that is, the cup wall is located between the kit 11 and the support plate 12. At this time, the hand mixer is vertically suspended on the cup wall. Therefore, when whipping, the hand mixer can be vertically suspended on the cup wall. Then, due to its own properties or the setting of the rotating structure, the connecting part allows the kit 11 to move. Thus, the handle 2 can be moved, thereby driving the whipping head 3 to move to different positions, such as swinging left and right or / and swinging back and forth. At the same time, the kit 11 and the support plate 12 can move synchronously, that is, slide along the cup wall.

[0051] Furthermore, the structure of the connecting part can be elastic and deformable, or the connecting part can be in the form of a hinge, that is, including at least one hinge shaft or hinge ball. For example... Figures 1-6 As shown, the whipping head is detachably mounted on the handle 2. The specific structure is as follows: First, the end of the connecting rod 32 connected to the handle 2 is provided with a mounting part 34, and the mounting part 34 has a card interface 341 that is compatible with the handle 2.

[0052] Meanwhile, the corresponding handle 2 has the following structure: First, the handle 2 has a built-in motor 4, and one end of the motor 4 is provided with a drive shaft 41. The drive shaft 41 passes through the handle 2 and protrudes. The protruding end of the drive shaft 41 is fitted with a connector 5, and the outer side of the connector 5 is provided with a buckle 51.

[0053] Therefore, in actual use, the whipping head is installed by fitting the mounting part 34 onto the outside of the connector 5 and placing the buckle 51 inside the card interface 341. When disassembling, it can be pulled outwards. Thus, the whipping head is detachably mounted on the handle 2, allowing for easy disassembly and cleaning, thereby reducing contact between the handle and water, and also facilitating the replacement of the whipping head.

[0054] Furthermore, a protruding plate 342 is provided on the outer side of the mounting component 34, and the height of the end of the protruding plate 342 near the mounting component 34 is lower than the height of the end of the protruding plate 342 away from the mounting component 34. Therefore, in actual use, the protruding plate 342 can play a role in flow restriction, that is, restricting the flow of liquid to the handle 2, thereby protecting the handle 2. Moreover, the protruding plate 342 is inclined, that is, the structure is higher on the outside and lower on the inside, so that the liquid flows inward instead of flowing outward and towards the handle 2.

[0055] Meanwhile, the specific structure of the mounting component 34 is as follows: First, a channel 343 is opened in the middle of the mounting component 34, and a protrusion 345 is provided on the inner wall of the channel 343. Furthermore, the card interface 341 is opened on the outer side of the mounting component 34 below the protrusion 345. Therefore, in actual use, the end of the whipping head 3 connected to the handle 2 is located inside the channel 343 and on the protrusion 345. The connection between the whipping head 3 and the mounting component 34 is injection molded. Simultaneously, the connector 5 of the handle 2 is located inside the channel 343 and below the protrusion 345.

[0056] like Figure 7 and Figure 8 As shown, the handle 2 has a built-in motor 4 and circuit board 6. The motor 4 is connected to the whipping head and electrically connected to the circuit board 6. Therefore, in actual use, the motor 4 will drive the whipping head to rotate after receiving the information sent by the circuit board 6.

[0057] Meanwhile, the circuit board 6 is provided with a contact 61, and the handle 2 is provided with a pusher 7 corresponding to the contact 61. The pusher 7 includes a push plate 71 and a push part 74 provided at the bottom of the push plate 71. By pushing the pusher 7, the push part 74 makes contact with the contact 61, thereby sending information to the circuit board 6, that is, the information for the circuit board 6 to drive the motor 4. There are two push parts 74, and the contact 61 is located between the two.

[0058] Secondly, the other structures of the pusher 7 are as follows: First, two connecting plates 72 are symmetrically arranged at the bottom of the push plate 71, and a locking block 73 is provided at the end of the connecting plate 72 away from the push plate 71. Therefore, in actual use, the end of the connecting plate 72 away from the push plate 71 passes through the handle 2 and is located inside the handle 2, and the locking block 73 abuts against the inner wall of the handle 2 to prevent the pusher 7 from detaching from the handle 2. Furthermore, for sealing, a sealing ring 8 is provided between the push plate 71 and the outer side of the handle 2.

[0059] Furthermore, the handle 2 has a storage slot 22 for placing the push plate 71 and allowing the push plate 71 to move, and the handle 2 has an elongated hole 23 for the connecting plate 72 to pass through and move, and the handle 2 has a connecting groove 21 for placing the sealing ring 8.

[0060] Simultaneously, the top of the push plate 71 has a slot to facilitate finger insertion, and the slot is provided with a protrusion 75 to increase friction and further facilitate pushing. Figure 2 As shown, the handle 2 also has a built-in power supply 9, which is used to provide power to the motor 4. The handle 2 includes a housing and upper and lower cover plates. The upper and lower cover plates are located inside the housing and are sealed with a seal between them. The lower cover plate also has a cover and a charging port on its outer side, and the cover is used to protect the charging port.

[0061] Meanwhile, the drive shaft 41 passes through the upper cover and is exposed. The upper cover has a slot so that the exposed end of the drive shaft 41 and the connecting piece 5 are mostly located in the slot, which can play a protective role. In addition, a sealing ring 8 is provided between the push plate 71 and the housing, and the locking block 73 abuts against the inner wall of the housing.

[0062] 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.
