Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a handheld mixer. Background Technology

[0002] Most of the adjustable hand blenders currently available on the market have an unlock button and a speed control button that are located on opposite sides of the blender and are separate from each other. When using them, you need to press the unlock button with one finger and then press the speed control button with the other finger to adjust the speed.

[0003] For example, Chinese utility model patent CN219846232U discloses a mixer, including a housing, a control board, a switch board, and a motor assembly installed inside the housing. The control board and the switch board are respectively connected to the motor assembly. The mixer also includes a speed control button assembly and an unlock button assembly installed on the housing. The speed control button assembly is connected to a potentiometer installed on the control board. When the speed control button assembly is pressed, it contacts the switch on the switch board to start the motor assembly. The output resistance of the potentiometer changes with the pressing depth of the speed control button assembly to change the speed of the motor assembly. The unlock button assembly includes a connecting rod and an unlock button. The present invention includes a key and a connecting rod spring. The connecting rod is movable in its axial direction and has a first position and a second position. In the first position, the connecting rod can stop the speed control button assembly to lock it. When the unlock button is pressed, it can apply a force to the connecting rod to move it from the first position to the second position, thereby releasing the locking of the speed control button assembly. In the second position, the connecting rod is disengaged from the speed control button assembly to release the locking of the speed control button assembly. The connecting rod spring applies a force to the connecting rod to move it from the second position to the first position, so that the connecting rod can return to the first position. This prior art combines the switch button and the speed control button, achieving speed adjustment by adjusting the pressing depth of the speed control button assembly, making operation more convenient. The unlock button assembly enables locking and unlocking of the speed control button assembly, improving the safety of the mixer. However, this prior art requires one finger to press the unlock button and another finger to press the speed control button when holding and using the mixer, which is very inconvenient.

[0004] Therefore, existing technologies still need to be improved and developed to address the aforementioned issues. Utility Model Content

[0005] The purpose of this invention is to provide a handheld mixer in response to the defects and shortcomings of the existing technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a handheld mixer, including a housing, an unlocking component, a speed control button, a control component and a motor assembly disposed within the housing. Specifically, the housing includes a front shell, a rear shell, a top cover, and a bottom connector. The unlocking component and the speed control button are disposed on the front shell. The outer side of the rear shell may have anti-slip texture. The upper end of the connector is connected to the motor assembly, and the lower end is connected to the stirring rod assembly. All of the above are prior art and will not be described in detail here. The unlocking component includes an unlocking button. Both the unlocking button and the speed control button are disposed on the housing and can move up and down. The control component is electrically connected to the motor assembly. The control component includes a speed control element for adjusting the speed of the motor assembly. The speed control button is correspondingly disposed to the speed control element. More specifically, the speed control button can be directly connected to the speed control element or connected through a transmission structure. When the speed control button is pressed, the speed control button directly touches the speed control element or touches the speed control element through the transmission structure. Both connection methods can change the output resistance of the speed control element by changing the pressing depth of the speed control button, thereby changing the speed of the motor assembly.

[0008] The unlock button has a pressing part A, and the speed adjustment button has a pressing part B. The pressing parts A and B are arranged adjacent to each other or nested within each other. More specifically, the entire pressing part A can be located to the left or right of the pressing part B, or the pressing part A can be located inside the pressing part B, or the pressing part B can be located inside the pressing part A. When the entire pressing part A is located to the left or right of the pressing part B, when using this invention, the operator only needs to hold the upper part of the shell and press the pressing part A and the pressing part B horizontally with one finger. In addition, the pressing surfaces of the pressing parts A and B can be flush, or the pressing surface of the pressing part A can be higher than the pressing surface of the pressing part B. When the pressing surfaces of the pressing parts A and B are flush, because human fingers naturally have a slight curvature, it is still possible to touch the pressing part A first.

[0009] The unlocking component also includes a slider, which is reciprocally mounted on the housing. The slider can be configured to reciprocate left and right or up and down. It has a first position and a second position in its direction of movement. When the slider is in the first position, it locks the speed control button. Pressing the pressing part A moves the slider from the first position to the second position, releasing the lock on the speed control button. Pressing the pressing part B engages the speed control element, thereby changing the output resistance of the speed control element to adjust the speed of the motor assembly. With this structure, when using this product, the user holds the upper part of the mixer's housing. When speed adjustment is needed, one finger presses down, first touching the pressing part A of the unlocking button to unlock the speed control button, and then touching the pressing part B to adjust the speed. Unlocking and speed adjustment can be completed with just one finger, making operation simple and convenient.

[0010] According to the above scheme, the pressing part B is provided with a mounting position, and the pressing part A of the unlock button is placed in the mounting position of the pressing part B. More specifically, the mounting position can be a through-hole structure that extends both inside and outside, and the pressing part of the unlock button is placed on the mounting position. With the above structural arrangement, the pressing part A is located inside the pressing part B, which makes the overall integrity of the blender's pressing button better, and the pressing part A is not easy to detach.

[0011] According to the above scheme, a mounting chamber is provided on the housing, and the unlocking button, slider, and speed control button are all located in the mounting chamber. This structural arrangement facilitates the mounting of the unlocking component and speed control button onto the housing via the mounting chamber.

[0012] According to the above scheme, the inner side of the unlock button is formed with an inclined surface A, the inner side of the speed control button is fixedly provided with a protrusion A, and the slider is provided with an inclined surface B and a protrusion B. The inclined surface B cooperates with the inclined surface A, and the protrusion B overlaps with the protrusion A. When the pressing part A is pressed, the inclined surface A presses against the inclined surface B, thereby pushing the slider from the first position to the second position, causing the protrusion B to be misaligned with the protrusion A, thus unlocking the speed control button. With the above structural setting, the stop lock of the speed control button can be released when the pressing part A of the unlock button is pressed.

[0013] According to the above scheme, the unlocking component further includes a reset spring, the slider is also provided with a first limiting block, and a second limiting block is fixedly provided in the mounting cavity. The first end of the reset spring is installed on the first limiting block, and the second end of the reset spring is installed on the second limiting block. With the above structural configuration, when the pressing part A of the unlocking button is pressed down, the slider moves from the first position to the second position, causing the first limiting block of the slider to squeeze the reset spring in the direction of the slider's movement. When the user releases the unlocking button, the pushing force acting on the slider disappears, the reset spring returns to its original state, and the slider moves back to the initial position, i.e., the first position, through the first limiting block, thus achieving the reset of the slider. Preferably, a buckle is fixedly provided in the mounting cavity, and the buckle is engaged with the slider. Specifically, the buckle does not affect the reciprocating movement of the slider, and can realize the installation of the slider in the mounting cavity.

[0014] According to the above scheme, the control component includes a control panel, and the speed regulating element is fixed on the control panel. The speed regulating element is a sliding resistor. The transmission structure includes a sliding bracket, a support column, a first spring, and a sliding handle. The sliding bracket has a first sliding cavity inside. One end of the support column is fixed to the control panel, and the other end of the support column is placed in the first sliding cavity. The first spring is placed in the first sliding cavity, and the first end of the first spring abuts against the support column, and the second end of the first spring abuts against the support column. A socket is opened on the outside of the sliding bracket, and the first end of the sliding handle is placed in the socket. The second end of the sliding handle is slidably connected to the sliding resistor. The speed regulating button abuts against the sliding bracket. With the above structural arrangement, the speed regulating button can drive the sliding handle to move on the sliding resistor to adjust the output resistance of the sliding resistor, thereby realizing the speed regulation of the motor assembly.

[0015] According to the above scheme, the control component also includes a micro switch. Specifically, the micro switch is used to start and stop the motor assembly. The micro switch is fixed on the control panel, and a pin is sleeved on the control end of the micro switch. The sliding bracket also has a second sliding cavity inside, and a second spring is provided in the second sliding cavity. The end of the pin away from the micro switch is placed in the second sliding cavity. The first end of the second spring passes through the pin and abuts against the control end of the micro switch, and the second end of the second spring abuts against the sliding bracket. With the above structural arrangement, when the speed control button is pressed, the second spring is also compressed, ensuring that the second spring can effectively trigger the micro switch and start the motor assembly under different pressing strokes of the speed control button.

[0016] According to the above scheme, the speed control button is mounted on the opening of the mounting chamber, and the unlock button is located between the speed control button and the mounting chamber. A first rotating shaft and a second rotating shaft are fixedly mounted on the mounting chamber. A first through hole is also provided within the mounting chamber. The speed control button is rotatably connected to the first rotating shaft. A control part is located at the end of the speed control button away from the first rotating shaft, and the control part abuts against the sliding bracket through the first through hole. The end of the unlock button away from the inclined surface A is rotatably connected to the second rotating shaft. With the above structural arrangement, the speed control button and the unlock button can be mounted on the mounting chamber, and the speed control button can move up and down around the first rotating shaft, and the unlock button can move up and down around the second rotating shaft.

[0017] According to the above scheme, the control unit is provided with a barb, which engages with the inner port of the first through hole. Through this structural design, the barb prevents the control unit of the speed control button from detaching from the mounting chamber, while not affecting the control unit's contact with the sliding bracket.

[0018] According to the above scheme, the housing includes a front shell and a rear shell, and the mounting chamber is formed on the front shell. Both the first rotating shaft and the second rotating shaft are fixedly connected to the inner wall of the mounting chamber. Alternatively, the first rotating shaft is fixed to the inner wall of the mounting chamber, a fixing bracket is provided on the inner side of the rear shell, and a clearance groove is formed at the bottom of the mounting chamber. The end of the fixing bracket away from the rear shell passes through the clearance groove and is fixedly connected to the second rotating shaft. With the above structural configuration, the first and second rotating shafts can be fixedly installed.

[0019] The beneficial effects of this utility model are:

[0020] When using this product, the user holds the upper part of the mixer's casing. When speed adjustment is needed, one finger presses down to first touch the pressing part A of the unlock button to unlock the speed adjustment button, and then touches the pressing part B of the speed adjustment button to adjust the speed. Unlocking and speed adjustment can be completed with just one finger, making the operation simple and convenient. Attached Figure Description

[0028] The technical solution of this utility model will be described below with structural drawings and embodiments. Example

[0029] like Figure 1-5As shown, this utility model provides a handheld mixer, including a housing 1, an unlocking component 2, a speed control button 3, and a control component 4 and a motor component 5 installed inside the housing 1. Specifically, the housing 1 includes a front shell 11, a rear shell 12, a top cover 13, and a bottom connector 14. The unlocking component 2 and the speed control button 3 are located on the front shell 11. The outer side of the rear shell 12 may be provided with anti-slip texture. The upper end of the connector 14 is connected to the motor component 5, and the lower end is connected to the stirring rod component 6. All of the above are prior art and will not be described in detail here. The unlocking component 2 includes an unlocking button 21. Both the unlocking button 21 and the speed control button 3 are movable up and down on the front shell 11. On the housing 1, the control component 4 is electrically connected to the motor assembly 5. The control component 4 includes a speed regulating element 42 for adjusting the speed of the motor assembly 5. The speed regulating button 3 is correspondingly provided with the speed regulating element 42. More specifically, the speed regulating button 3 can be directly connected to the speed regulating element 42 or connected through the transmission structure 7. When the speed regulating button 3 is pressed, the speed regulating button 3 directly touches the speed regulating element 42 or touches the speed regulating element 42 through the transmission structure 7. Both connection methods can change the output resistance of the speed regulating element by changing the pressing depth of the speed regulating button 3, thereby changing the speed of the motor assembly. In this embodiment, the connection is preferably made through the transmission structure 7.

[0030] The unlock button 21 is provided with a pressing part A211, and the speed adjustment button 3 is provided with a pressing part B31. The pressing parts A211 and B31 are arranged adjacent to each other or nested together, so that one finger can press the pressing parts A211 and B31 one after the other. More specifically, the pressing part A211 can be located entirely on the left or right side of the pressing part B31, or the pressing part A211 can be located inside the pressing part B31, or the pressing part B31 can be located inside the pressing part A211. When the pressing part A211 is entirely located on the left or right side of the pressing part B31, when using this utility model, the operator only needs to hold the upper part of the housing 1 with their hand, and one finger can press the pressing part A211 and the pressing part B31 in sequence. In addition, the pressing surfaces of the pressing part A211 and the pressing part B31 can be flush, or the pressing surface of the pressing part A211 can be higher than the pressing surface of the pressing part B31. When the pressing surfaces of the pressing part A211 and the pressing part B31 are flush, because human fingers are naturally slightly curved, it is still possible to touch the pressing part A211 first. As mentioned above, the pressing part A211 and the pressing part B31 can be nested together. In this preferred embodiment, a mounting position 311 is provided on the pressing part B31. The mounting position 311 is a through hole structure that extends through the inside and outside. The pressing part A211 of the unlocking button 21 is placed on the mounting position 311, and the pressing surface of the pressing part A211 is higher than the pressing surface of the pressing part B31. When using this utility model, the operator only needs to hold the upper part of the housing 1 with one hand, press the pressing part A211 with one finger, and then press the pressing part B31 as the pressing part A211 moves down.

[0031] The unlocking component 2 also includes a slider 22, which is reciprocally mounted on the housing 1. It should be noted that the slider 22 can be configured to reciprocate left and right, or up and down. Figure 4-5 As shown, in this preferred embodiment, the slider 22 is configured to reciprocate up and down, and the slider 22 has a first position in its direction of movement (e.g., Figure 4 (as shown) and the second position (as shown) Figure 5As shown, when the slider 22 is in the first position, it locks the speed control button 3. Pressing the pressing part A211 moves the slider 22 from the first position to the second position, releasing the lock on the speed control button 3. Pressing the pressing part B31 causes it to contact the speed control element 42, thereby changing the output resistance of the speed control element 42 to adjust the speed of the motor assembly 5. With this structure, when using this product, the user holds the upper part of the mixer's housing 1. When speed adjustment is needed, one finger presses down, first touching the pressing part A211 of the unlock button 21 to unlock the speed control button 3, and then touching the pressing part B31 of the speed control button 3 to adjust the speed. Unlocking and speed adjustment can be completed with just one finger, making the operation simple and convenient.

[0032] Furthermore, the housing 1 has an installation chamber 15, and the unlocking button 21, the slider 22, and the speed control button 3 are all located within the installation chamber 15. This structural arrangement facilitates the installation of the unlocking assembly 2 and the speed control button 3 onto the housing 1 via the installation chamber 15.

[0033] Furthermore, such as Figure 4-5 As shown, the inner side of the unlock button 21 has an inclined surface A212, the inner side of the speed control button 3 has a protrusion A32, and the slider 22 has an inclined surface B221 and a protrusion B222. The inclined surface B221 cooperates with the inclined surface A212, and the protrusion B222 overlaps with the protrusion A32. When the pressing part A211 is pressed down, the inclined surface A212 presses against the inclined surface B221, thereby pushing the slider 22 to move from the first position to the second position, causing the protrusion B222 to be misaligned with the protrusion A32. With the above structural arrangement, the stop lock of the speed control button 3 can be released when the pressing part A211 of the unlock button 21 is pressed. In this embodiment, the inclined surface A212 faces upward and the inclined surface B221 faces downward. When the pressing part A211 is pressed, the pressing part A211 moves inward, causing the inclined surface A212 to press against the inclined surface B221 upward, causing the slider 22 to move upward, so that the protrusion B222 of the slider 22 is misaligned with the protrusion A32 of the speed adjustment button 3. Then, the same finger continues to press the pressing part B31 of the speed adjustment button 3 to adjust the speed.

[0034] Furthermore, the unlocking component 2 also includes a reset spring 23, the slider 22 is provided with a first limiting block 223, and a second limiting block 151 is fixedly provided in the mounting chamber 15. The first end of the reset spring 23 is mounted on the first limiting block 223, and the second end of the reset spring 23 is mounted on the second limiting block 151. With the above structural configuration, when the pressing part A211 of the unlocking button 21 is pressed down, the slider 22 moves from the first position to the second position, causing the first limiting block 223 of the slider 22 to squeeze the reset spring 23 in the direction of the slider 22's movement. When the user releases the unlocking button 21, the pushing force acting on the slider 22 disappears, the reset spring 23 returns to its original state, and the first limiting block 223 moves the slider 22 back to the initial position, i.e., the first position, thus resetting the slider 22.

[0035] Furthermore, a latch 152 is fixedly provided within the mounting chamber 15, and the latch 152 engages with the slider 22. Specifically, the latch 152 does not affect the reciprocating motion of the slider 22. Through the above structural arrangement, the slider 22 can be installed within the mounting chamber 15. Preferably, in this embodiment, two latches 152 are provided, and the two latches 152 are symmetrically arranged, which can limit the movement of both sides of the slider 22.

[0036] Furthermore, the control component 4 includes a control panel 41, the speed regulating element 42 is fixed on the control panel 41, the speed regulating element 42 is a sliding resistor, the transmission structure 7 includes a sliding bracket 71, a support column 72, a first spring 73 and a slider 74, the sliding bracket 71 has a first sliding cavity 711 inside, one end of the support column 72 is fixed on the control panel 41, the other end of the support column 72 is placed in the first sliding cavity 711, the first spring 73 is placed in the first sliding cavity 711, and the first end of the first spring 73 abuts against the support column 72, the second end of the first spring 73 abuts against the support column 72, the sliding bracket 71 has an insertion hole 712 on the outside, the first end of the slider 74 is placed in the insertion hole 712, the second end of the slider 74 is slidably connected to the sliding resistor, and the speed regulating button 3 abuts against the sliding bracket 71. With the above structural setup, the speed control button 3 can drive the slider 74 to move on the sliding resistor to adjust the output resistance of the sliding resistor, thereby achieving speed control of the motor assembly 5.

[0037] Furthermore, the control component 4 also includes a micro switch 43. Specifically, the micro switch 43 is used to start and stop the motor assembly 5. The micro switch 43 is fixed to the control panel 41. A pin 75 is sleeved on the control end of the micro switch 43. The sliding bracket 71 also has a second sliding cavity 713 inside. A second spring 76 is provided in the second sliding cavity 713. The end of the pin 75 away from the micro switch 43 is placed in the second sliding cavity 713. The first end of the second spring 76 passes through the pin 75 and abuts against the control end of the micro switch 43. The second end of the second spring 76 abuts against the sliding bracket 71. With the above structural arrangement, when the speed adjustment button 3 is pressed, the second spring 76 is also compressed, ensuring that the second spring 76 can effectively trigger the micro switch 43 and start the motor assembly 5 under different pressing stroke states of the speed adjustment button 3.

[0038] Furthermore, the speed control button 3 is positioned over the opening of the mounting chamber 15, and the unlocking button 21 is located between the speed control button 3 and the mounting chamber 15. A first rotating shaft 153 and a second rotating shaft 154 are fixedly mounted on the mounting chamber 15. A first through hole 155 is also provided inside the mounting chamber 15. The speed control button 3 is rotatably connected to the first rotating shaft 153. A control part 33 is located at the end of the speed control button 3 away from the first rotating shaft 153. The control part 33 abuts against the sliding bracket 71 through the first through hole 155. The end of the unlocking button 21 away from the inclined surface A212 is rotatably connected to the second rotating shaft 154. With this structural arrangement, the speed control button 3 and the unlocking button 21 can be installed on the mounting chamber 15, and the speed control button 3 can move up and down around the first rotating shaft 153, while the unlocking button 21 can move up and down around the second rotating shaft 154.

[0039] Furthermore, the control unit 33 is provided with a barb 331, which engages with the inner port of the first through hole 155. Through this structural arrangement, the barb 331 prevents the control unit 33 of the speed control button 3 from disengaging from the mounting chamber 15, while not affecting the control unit 33 of the speed control button 3 from pressing against the sliding bracket 71.

[0040] Furthermore, the housing 1 includes a front housing 11 and a rear housing 12, and the mounting chamber 15 is formed on the front housing 11. The first rotating shaft 153 and the second rotating shaft 154 are both fixedly connected to the inner wall of the mounting chamber 15. Through the above structural arrangement, the first rotating shaft 153 and the second rotating shaft 154 can be fixedly installed. Example
