A few blenders are rechargeable; while they don't have a power cord, the battery pack is internal and non-removable. After use, the battery pack must be recharged for the next use. When the battery pack is depleted, it cannot be replaced, greatly reducing work efficiency. Furthermore, if the battery pack malfunctions or is damaged, the entire blender needs to be replaced, significantly increasing replacement costs.

[0003] In addition, the battery pack inside most existing mixers is fixed in the working part of the mixer. Since the working part also houses the drive motor, the battery pack is usually located on the side of the drive motor, which greatly increases the weight of the working part of the mixer. This makes it difficult for the operator to hold the mixer and makes it difficult to place the mixer stably on the table.

[0073] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0074] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0076] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0077] like Figure 1 and Figure 2As shown, this embodiment provides a mixer capable of mixing objects. Specifically, the mixer is a handheld mixer, including a working part 1, a grip part 3, a mixing assembly 2, and a drive assembly 5. The grip part 3 is connected to one side of the working part 1, and the mixing assembly 2 is rotatably mounted on the working part 1. When the operator holds the grip part 3 and turns on the mixer, the drive assembly 5 drives the mixing assembly 2 to rotate relative to the working part 1, thereby achieving the mixing effect on the object. Specifically, in this embodiment, two sets of mixing assemblies 2 are spaced apart, and the drive assembly 5 drives the two sets of mixing assemblies 2 to rotate synchronously, and the two sets of mixing assemblies 2 rotate in opposite directions, further improving the mixing efficiency of the mixer.

[0078] Now combined Figure 2 and Figure 3 The specific structure of driver component 5 is described below, such as... Figure 2 and Figure 3 As shown, the working part 1 has a drive chamber 11 inside, and the drive assembly 5 is housed in the drive chamber 11. The drive assembly 5 includes a drive motor 51, a transmission component 52, a mounting shaft 53, and a mounting plate 54. The mounting plate 54 is fixed in the drive chamber 11, and the drive motor 51 is fixed on the mounting plate 54. The output end of the drive motor 51 is connected to the transmission component 52. The mounting shaft 53 is connected to the transmission component 52, and one end of each of the two sets of stirring assemblies 2 can extend into the working part 1 and be inserted and fixed in the mounting shaft 53. When the drive motor 51 rotates, it can drive the two sets of stirring assemblies 2 to rotate through the transmission component 52 and the mounting shaft 53, thereby realizing the stirring effect of the stirring assembly 2.

[0079] Specifically, in this embodiment, the transmission component 52 includes a worm gear 521 and two sets of turbines 522. The worm gear 521 is connected to the output end of the drive motor 51. The two opposite sides of the worm gear 521 are respectively engaged with the two sets of turbines 522. The turbines 522 are rotatably mounted on the mounting plate 54. Each turbine 522 is connected to a mounting shaft 53. When the drive motor 51 drives the worm gear 521 to rotate, the worm gear 521 can synchronously drive the two sets of turbines 522 to rotate, thereby realizing the synchronous rotation of the two sets of stirring components 2 in opposite directions. In this embodiment, the machine can have three speed settings: the drive motor 51 in the low speed setting is 450 r / min to 550 r / min, the drive motor 51 in the medium speed setting is 900 r / min to 1100 r / min, and the drive motor 51 in the high speed setting is 1400 r / min to 1600 r / min. In this embodiment, the preferred speed settings are 500 r / min for the low speed setting, 1000 r / min for the medium speed setting, and 1500 r / min for the high speed setting.

[0080] It should be noted that the mixing component 2 and the corresponding mounting shaft 53 are plug-in connected. By changing the type of mixing component 2, the mixer can be used to mix different substances. For example, by replacing the mixing component 2 with a whisk, the mixer can be used to beat eggs; or by replacing the mixing component 2 with a dough mixer, the mixer can be used to knead dough, greatly improving the versatility of the mixer.

[0081] In this embodiment, the stirring assembly 2 includes a stirring head 21 and a connecting rod 22 connected to each other. The connecting rod 22 can be inserted and fixed in the mounting shaft 53, thereby realizing the transmission connection between the mounting shaft 53 and the stirring assembly 2. The various forms of stirring assemblies 2 differ only in the specific form of the stirring head 21.

[0082] Preferably, such as Figure 3 As shown, the outer peripheral wall of the connecting rod 22 is provided with a plugging protrusion 221, and the plugging end of the mounting shaft 53 is provided with a slot 531. The plugging protrusion 221 can be plugged and fixed in the slot 531, thereby achieving the fixation between the connecting rod 22 and the slot 531. When an external force away from the mounting shaft 53 is applied to the stirring assembly 2, the slot 531 can undergo a slight deformation and increase under the action of the external force, causing the plugging protrusion 221 to disengage from the slot 531, thereby achieving the disassembly of the stirring assembly 2. When it is necessary to install the stirring assembly 2, the stirring assembly 2 can be directly inserted into the slot 531, which is convenient to operate.

[0083] To ensure the normal operation of driver component 5, such as Figure 3 As shown, the drive assembly 5 also includes a cooling fan 55, which is located above the drive motor 51. The cooling fan 55 is connected to the top of the worm gear 521. When the drive motor 51 rotates, it can synchronously drive the cooling fan 55 to work, thereby cooling the drive motor 51 and ensuring the normal operation of the drive motor 51.

[0084] Most existing blenders are corded, requiring the power cord to be plugged into a power source, significantly limiting their usability. A few are rechargeable, without a power cord, but the battery pack is internal and non-removable. After use, the battery pack must be recharged for the next use. When the battery is depleted, it cannot be replaced; it must be fully charged before use, greatly reducing efficiency. Furthermore, if the battery pack malfunctions or is damaged, the entire blender must be replaced, significantly increasing replacement costs. Additionally, the battery pack in most existing blenders is fixed within the working section 1. Since the working section 1 houses the drive motor 51, the battery pack is usually located to one side of the drive motor 51, greatly increasing the weight of the working section 1. This makes it difficult for the operator to hold the blender using the grip 3 and to place the blender stably on a table.

[0085] To solve the above problems, such as Figure 2 As shown, the blender is equipped with a battery compartment 31, in which a detachable battery pack 4 is housed. The battery pack 4 powers the drive assembly 5, facilitating the removal of damaged or depleted battery packs 4 from the battery compartment 31 for replacement, thus reducing replacement costs and ensuring the blender's working efficiency. Furthermore, the battery compartment 31 extends from the grip 3 towards the working part 1, with at least a portion of the battery compartment 31 positioned above the grip 3. This arrangement ensures that the blender with the battery pack 4 inserted has its center of gravity closer to the grip 3 than a blender without the battery pack 4 inserted. This arrangement of the battery compartment 31 relative to the drive compartment 11 not only reduces the overall size of the machine but also provides an optimal center of gravity position, making the blender more stable and evenly weight-distributed, thus requiring less effort from the user when holding the grip 3.

[0086] Preferably, in this embodiment, the outer surface of the battery pack 4 housed in the battery compartment 31 can be used as part of the outer surface of the grip part 3, making the overall appearance of the mixer more aesthetically pleasing.

[0087] In this embodiment, the battery pack 4 has an irregular shape to ensure that the operator can accurately install the battery pack 4 into the battery compartment 31. Furthermore, the battery pack 4 houses three batteries arranged in a circular pattern inside the battery pack 4, making full use of the internal space and minimizing the volume of the battery pack 4, resulting in a more compact overall structure. It should be noted that in other embodiments, if two, four, or even more batteries are used, it is sufficient to ensure that each battery is arranged in a circular pattern inside the battery pack 4.

[0088] Preferably, such as Figure 2As shown, the battery pack 4 is placed horizontally in the battery compartment 31, and the angle of downward tilt of the battery pack 4 from one side of the working part 1 to the side of the grip part 3 is greater than or equal to 3° and less than or equal to 8°, so that the outer surface of the battery pack 4 and the outer surface of the grip part 3 are in the same plane, making the appearance of the grip part 3 more flat and aesthetically pleasing. In addition, the tilting setting of the battery pack 4 also causes the weight of the battery pack 4 to tilt towards the side of the grip part 3, thereby better balancing the weight of the drive motor 51 and making the structure of the entire mixer more compact. Considering the overall height and length of the machine, in this embodiment, the angle of downward tilt of the battery pack 4 from one side of the working part 1 to the side of the grip part 3 is preferably 5°.

[0089] Furthermore, in this embodiment, the drive motor 51 is vertically placed in the drive chamber 11, and the ratio of the outer diameter of the drive chamber 11 to the outer diameter of the battery chamber 31 is greater than or equal to 1.2 and less than or equal to 1.5. This arrangement can make more rational use of the internal space of the mixer, making the overall structure of the machine more compact. Specifically, in this embodiment, the outer diameter of the drive chamber 11 ranges from 78mm to 82mm, the outer diameter of the battery chamber 31 ranges from 55mm to 65mm, and preferably, the outer diameter of the drive chamber 11 is 81mm, the diameter of the drive motor 51 is 36mm, and the outer diameter of the battery chamber 31 is 60mm.

[0090] Furthermore, in this embodiment, such as Figure 4 As shown, the ratio of the diameter d1 of the battery pack 4 to the diameter d2 of the outer casing at the location of the battery compartment 31 in the mixer is 0.6 ≤ D ≤ 0.8. The diameter d1 of the battery pack 4 is 40mm to 45mm, and in this embodiment, the diameter d1 of the battery pack 4 is preferably 42mm. The diameter d2 of the outer casing at the location of the battery compartment 31 in the mixer is 50mm to 75mm, and in this embodiment, the diameter d2 of the outer casing at the location of the battery compartment 31 in the mixer is preferably 56mm.

[0091] Furthermore, in this embodiment, such as Figure 5 As shown, the ratio H1 of the length h1 of the battery pack 4 to the length h2 of the mixer is 0.4 ≤ H1 ≤ 0.53. The length h1 of the battery pack 4 is 80mm to 90mm, and in this embodiment, the length of the battery pack 4 is preferably 84mm. The length h2 of the mixer is 170mm to 180mm, and in this embodiment, the length h2 of the mixer is preferably 172mm.

[0092] In this embodiment, as Figure 2As shown, the mixer also includes a locking component 6, which is disposed on the top of the grip portion 3. The locking component 6 can cooperate with the battery pack 4 to lock the battery pack 4 in the battery compartment 31, thereby achieving a stable fixation of the battery pack 4 in the battery compartment 31. Specifically, the locking component 6 includes a locking member 61 and a first reset member (not shown in the figure). The locking member 61 is pivotally connected to the inner wall of the battery compartment 31, and the locking member 61 locks the battery pack 4 under the action of the first reset member. In this embodiment, the first reset member is a spring, which has good elasticity and a simple structure, making it easy to install.

[0093] In addition, such as Figure 2 As shown, the locking component 6 also includes an operation button 62, which protrudes from the top of the grip 3 and can slide relative to the grip 3. The locking component 61 includes a touch plate 611 and a locking protrusion 612. The touch plate 611 is pivotally connected to the inner wall of the battery compartment 31. One end of the touch plate 611 is sandwiched between the operation button 62 and the first reset component. The other end of the touch plate 611 is provided with a locking protrusion 612. The locking protrusion 612 and the first reset component are located on both sides of the pivot position of the touch plate 611. The locking protrusion 612 can hold the battery pack 4 against the battery compartment 31. It should be noted that a support frame 311 is connected to the battery compartment 31. The first reset member is clamped between the support frame 311 and the touch plate 611. When the operator presses the operation button 62, the operation button 62 presses down against the touch plate 611 relative to the grip part 3. At this time, the first reset member is compressed, causing the touch plate 611 to rotate relative to the battery compartment 31. The locking protrusion 612 disengages from the battery pack 4, making it easier for the operator to remove the battery pack 4 from the battery compartment 31. When the operator removes the pressure on the operation button 62, the touch plate 611 rotates in the opposite direction under the elastic restoring force of the first reset member, causing the locking protrusion 612 to reset and abut against the battery pack 4. In this embodiment, pressing the operation button 62 and moving it 3mm ensures that the vertical travel of the touch plate 611 is 3.5mm, which can achieve the separation of the locking protrusion 612 from the battery pack 4, making the operation convenient.

[0094] Preferably, such as Figure 2 As shown, a limiting plate 621 is provided around the lower end surface of the operation button 62. The limiting plate 621 can pass through the outer shell of the grip part 3 and abut against the inner wall of the grip part 3, thereby preventing the operation button 62 from disengaging from the grip part 3 under the elastic restoring force of the first reset member, and thus limiting the operation button 62.

[0095] In this embodiment, as Figure 2 , Figure 6 and Figure 7As shown, the outer wall of the battery pack 4 is provided with an abutment protrusion 41, and the snap-fit ​​protrusion 612 can abut against the abutment protrusion 41, thereby achieving the abutment and fixation of the battery pack 4 in the battery compartment 31. It should be noted that multiple abutment protrusions 41 are spaced apart on the outer wall of the battery pack 4. In this embodiment, as shown... Figure 7 As shown, two abutment protrusions 41 are spaced apart along the length of the battery pack 4, namely a first protrusion 411 and a second protrusion 412. The first protrusion 411 is near the bottom of the battery pack 4, and the second protrusion 412 is near the top of the battery pack 4. Figure 2 As shown, when the battery pack 4 is placed horizontally in the battery compartment 31, the snap-fit ​​protrusion 612 abuts against the first protrusion 411, as... Figure 6 As shown, when the battery pack 4 is placed in other forms of battery compartment 31 in other postures (e.g., vertical posture), the snap-fit ​​protrusion 612 abuts against the second protrusion 412, thereby improving the versatility of the battery pack 4. Preferably, the abutment depth between the snap-fit ​​protrusion 612 and the abutment protrusion 41 is 1mm to 2mm. While minimizing the overall size, this ensures the reliability and stability of the snap-fit ​​protrusion 612 and the abutment protrusion 41 in abutment fixation. In this embodiment, the abutment depth between the snap-fit ​​protrusion 612 and the abutment protrusion 41 is preferably 1.5mm.

[0096] To facilitate the removal of battery pack 4 from battery compartment 31 for replacement or charging, such as... Figure 2 As shown, the mixer also includes a release component 7. When the operation button 62 is pressed to disengage the locking protrusion 612 from the abutting protrusion 41 on the battery pack 4, the release component 7 can push the battery pack 4 out of the battery compartment 31, thereby making it easier for the operator to grab the end of the battery pack 4 that extends out of the battery compartment 31 and remove the battery pack 4.

[0097] Preferably, the release component 7 can push the battery pack 4 out of the battery compartment 31 by a distance of 5mm to 8mm. In this embodiment, 6mm is preferred, which not only makes it easier for the operator to hold the battery pack 4, but also prevents the battery pack 4 from falling out of the battery compartment 31 and causing damage.

[0098] Now combined Figure 2 The specific structure of release component 7 is explained as follows: Figure 2As shown, the release assembly 7 includes a release member 71 and a second reset member 72. The release member 71 is disposed on the bottom wall of the battery compartment 31 and abuts against the bottom wall of the battery pack 4. The release member 71 can push the battery pack 4 out of the battery compartment 31 under the action of the second reset member 72. In this embodiment, the second reset member 72 is a spring. Springs have good elasticity and simple structure, making them easy to install. Specifically, the release member 71 includes a connecting part 711 and an abutment 712. The connecting part 711 is fixed to the bottom wall of the battery compartment 31, and the abutment 712 is slidably connected to the connecting part 711. The abutment 712 abuts against the bottom wall of the battery pack 4, and the second reset member 72 is sandwiched between the connecting part 711 and the abutment 712. When the battery pack 4 is housed in the battery compartment 31, the abutment 712 is driven to move toward the connection part 711 and compress the second reset member 72 under the pressure of the bottom wall of the battery pack 4. When the operation button 62 is pressed to disengage the locking protrusion 612 from the abutment protrusion 41 on the battery pack 4, the abutment 712 is driven to move away from the connection part 711 under the elastic restoring force of the second reset member 72, thereby causing the abutment 712 to push the battery pack 4 out of the battery compartment 31.

[0099] In addition, such as Figure 6 As shown, the release assembly 7 also includes a protective pad 73. The protective pad 73 is fixed to the inner wall of the battery compartment 31 and is sandwiched between the inner wall of the battery compartment 31 and the outer wall of the battery pack 4. When the abutment 712 pushes the battery pack 4 out of the battery compartment 31, the protective pad 73 can limit the battery pack 4 from extending beyond the limit position of the battery compartment 31, thereby preventing the battery pack 4 from falling to the ground and being damaged under its own weight after being pushed out, thus improving the protection of the battery pack 4. Specifically, the protective pad 73 can be made of silicone, which not only ensures the friction between the silicone pad and the battery pack 4, but also creates a damping effect between the silicone pad and the battery pack 4, preventing the silicone pad from rubbing and damaging the battery pack 4. It should be noted that in other embodiments, the protective pad 73 can also be made of other materials, such as rubber, as long as the flexibility and friction of the protective pad 73 are ensured.

[0100] To facilitate the detachment of the stirring assembly 2 from the mounting shaft 53, such as Figure 5 and Figure 8 As shown, the mixer provided in this embodiment also includes a push rod assembly 8, which is disposed on the grip 3. The push rod assembly 8 can pass through the grip 3 and extend into the mounting shaft 53 inside the working part 1 to push the mixing assembly 2 away from the mounting shaft 53, so that the operator does not need to hold the mixing assembly 2 to pull it out, making the disassembly of the mixing assembly 2 more convenient.

[0101] Specifically, the push rod assembly 8 includes a push rod 81 and a third reset member 82. The push rod 81 is movably mounted on the gripping part 3 and can extend through the gripping part 3 into the mounting shaft 53 inside the working part 1 to push the stirring assembly 2 away from the mounting shaft 53. The third reset member 82 is clamped between the push rod 81 and the mounting plate 54. After pushing the stirring assembly 2, the third reset member 82 can move the push rod 81 away from the stirring assembly 2 to reset it, thereby removing the pushing force on the stirring assembly 2. Specifically, the third reset member 82 is a spring, which has good elasticity and a simple structure, making it easy to install.

[0102] In this embodiment, the push rod 81 includes a connecting frame 811 and a pushing head 812. Two sets of pushing heads 812 are spaced apart on the connecting frame 811, each set corresponding to a stirring assembly 2. By pressing the connecting frame 811, the two sets of pushing heads 812 are simultaneously driven by the connecting frame 811 to disassemble the two sets of stirring assemblies 2, making the operation convenient. It should be noted that a fixing head 8111 is provided on the connecting frame 811. One end of the third reset member 82 is sleeved in the fixing head 8111, and the other end of the third reset member 82 is sleeved and fixed in the positioning post of the mounting plate 54, thereby achieving the positioning and installation of the third reset member 82 between the connecting frame 811 and the mounting plate 54.

[0103] In addition, such as Figure 5 and Figure 8 As shown, the push rod assembly 8 also includes a push rod button 83. The push rod button 83 protrudes from the outer side of the grip 3 and can slide relative to the grip 3. The push rod button 83 covers one end of the connecting bracket 811. Pressing the push rod button 83 can drive the push rod assembly 81. In addition, the push rod button 83 is provided with a digital display, which can display the power level of the battery pack 4, so as to facilitate timely observation of the power level of the battery pack 4 and timely charging of the battery pack 4.

[0104] Preferably, such as Figure 8 As shown, the connecting frame 811 has a clearance hole 8112, which is used to avoid interference between the battery pack 4 and the push rod assembly 8 when the push rod assembly 8 moves relative to the gripping part 3, thereby achieving a compact arrangement between the various components. In addition, by having a clearance hole 8112 on the connecting frame 811, the diameter of the battery pack 4 in the battery compartment 31 is also reduced.

[0105] It should be noted that because the battery pack 4 is inclined downwards from one side of the working part 1 to the side of the gripping part 3, not only is the overall height of the machine reduced, but also space is saved for the movement of the push rod 81, ensuring that the ratio of the length h1 of the battery pack 4 to the length h3 of the push rod 81, H2, is 0.5 ≤ H2 ≤ 0.8. In this embodiment, as... Figure 5 As shown, since the length h1 of the battery pack 4 is 80mm to 90mm, the length of the battery pack 4 is preferably 84mm in this embodiment, and the length h3 of the push rod 81 provided in this embodiment is 100mm to 180mm, the length h3 of the push rod 81 is preferably 125mm in this embodiment.

[0106] In addition, such as Figure 2 As shown, the mixer also includes a control circuit board 9 and a speed control plate 10. The control circuit board 9 is housed in the drive chamber 11 and is positioned below the drive motor 51. A battery pack charging plate 42 is located on the side of the battery pack 4 near the drive motor 51. The control circuit board 9 can be electrically connected to both the drive motor 51 and the battery pack charging plate 42. The speed control plate 10 is located in the grip part 3 and is positioned between the battery pack charging plate 42 and the digital display. The battery pack charging plate 42 is electrically connected to the speed control plate 10, and the speed control plate 10 is electrically connected to the digital display. With this arrangement, when the push rod button 83 is pressed to push the push rod 81 to release the mixing assembly 2, the electrical wiring harness will not be pulled but will instead loosen, thus better protecting the wiring harness.

[0107] Furthermore, it should be noted that a power supply can be plugged into the control circuit board 9, and the battery pack charging board 42 can be charged through the control circuit board 9, thereby charging the battery pack 4. Figure 9 As shown, the blender also includes a charging base 20, which allows the battery pack 4 to be removed from the battery compartment 31 and placed in the charging base 20 for charging. The digital display is electrically connected to the battery pack charging plate 42 via the speed control plate 10, ensuring that the digital display accurately shows the battery pack 4's charge level and also displays the blender's speed setting. Since the specific working principle of this display is existing technology, it will not be elaborated upon here.
