[0029] Compared with existing technologies, this invention utilizes a variable signal converter. This converter changes its output electrical signal according to the vertical position of the main unit relative to the cooking cover and feeds this signal back to the control module. The control module then controls the motor speed based on the feedback signal from the variable signal converter. This allows for speed adjustment without the need for additional touch buttons, simplifying operation and improving the user experience.

[0030] Meanwhile, this invention enables the control module to control the motor's speed based on the operating mode selected by the mode controller and the electrical signal fed back by the variable signal converter. This allows for speed adjustment while the main unit moves, facilitating user operation. Furthermore, in different operating modes, based on the same electrical signal, the motor can output different speeds to achieve three-dimensional mixing and variable-speed turbulence cutting of food, resulting in faster and more efficient mixing. This avoids food jamming during the mixing process and produces a finer mixing effect. Attached Figure Description

[0049] Referring to Figures 1-10, a handheld blender with intelligent telescopic and variable speed capabilities includes:

[0050] The main unit 10 includes a control module 130, a motor 140 connected to the control module 130, and a mode controller 60. A cooking cover 20 is included, allowing the main unit 10 to move vertically relative to the cooking cover 20. A rotating shaft 30 is also included, moving vertically and rotating relative to the cooking cover 20, and is connected to the motor shaft of the motor 140. A blade head 310 is connected to the rotating shaft 30. A variable signal converter 40 is communicatively connected to the control module 130. The variable signal converter 40 changes its output electrical signal according to the vertical position of the main unit 10 relative to the cooking cover 20 and feeds this signal back to the control module 130. The control module 130 controls the speed of the motor 140 based on the electrical signal fed back from the variable signal converter 40. This allows for speed adjustment without additional touch buttons, facilitating user operation and improving the user experience.

[0051] The mode controller 60 is configured to switch the operating modes of the control module 130; the operating modes include at least two; the control module 130 controls the speed of the motor 140 according to the currently selected operating mode of the mode controller 60 and the electrical signal fed back by the variable signal converter 40. Under the action of the variable signal converter, as the main unit moves up and down relative to the mixing cover, the variable signal converter outputs different electrical signals. At this time, the operating mode selected by the control module controls the speed of the motor according to the electrical signal fed back by the variable signal converter. This allows for speed adjustment while the main unit moves, facilitating user operation. Furthermore, in different operating modes, based on the same electrical signal, different speeds can be controlled to output the motor, achieving three-dimensional spatial stirring and variable speed turbulence cutting of food, making it faster and more efficient, avoiding food jamming during the mixing process, and resulting in a finer mixing effect.

[0052] Referring to Figures 9 and 10, the user can operate the mode controller 60 to adjust to the desired working mode according to their needs. The control module 130 controls the speed of the motor 140 based on the electrical signal fed back from the variable signal converter 40 according to different working modes. The effect achieved is that, in different working modes, the same electrical signal can control the motor to output different speeds to meet different agitation requirements, and the different speed changes can achieve better agitation and avoid blade jamming.

[0053] In one embodiment of the variable signal converter 40, as shown in Figures 3 and 4, the variable signal converter 40 is a sliding rheostat with a sensing end 410 that slides up and down relative to the rheostat. When the main unit 10 moves up and down relative to the cooking cover 20, it synchronously drives the sensing end 410 to slide up and down relative to the rheostat. As the sensing end 410 slides up and down, the resistance value of the rheostat changes accordingly. The control module 130 controls the speed of the motor 140 based on different operating modes and the real-time resistance value of the rheostat. The rheostat is a commercially available product. Its principle is that as the sensing end 410 moves, its resistance value changes accordingly, and this resistance value is the electrical signal fed back by the variable signal converter. The control module 130 adjusts the speed of the motor according to this electrical signal.

[0054] In a second embodiment of the variable signal converter 40, the variable signal converter 40 is a Hall sensor, which is mounted on the main unit 10. A magnet that senses the Hall sensor is located on the cooking cover 20. The Hall sensor is connected to the control module 130. As the main unit 10 moves downward relative to the cooking cover 20, the Hall sensor gradually moves away from the magnet; conversely, as the main unit 10 moves upward relative to the cooking cover 20, the Hall sensor gradually moves closer to the magnet. In this embodiment, as the magnet moves away from or closer to the Hall sensor, the magnetic field signal it senses changes accordingly. This magnetic field signal is an electrical signal fed back by the variable signal converter. The control module 130 adjusts the motor speed according to this electrical signal.

[0055] In a third embodiment of the variable signal converter 40, the variable signal converter 40 is a Hall sensor, which is mounted on the cooking cover 20. A magnet that senses the Hall sensor is mounted on the main unit 10. The Hall sensor is connected to the control module 130. As the main unit 10 moves downward relative to the cooking cover 20, the Hall sensor gradually moves away from the magnet; conversely, as the main unit 10 moves upward relative to the cooking cover 20, the Hall sensor gradually moves closer to the magnet. In this embodiment, as the magnet moves away from or closer to the Hall sensor, the magnetic field signal it senses changes accordingly. This magnetic field signal is an electrical signal fed back by the variable signal converter. The control module 130 adjusts the motor speed according to this electrical signal.

[0056] Referring to Figures 3 and 4, in some embodiments, the main unit 10 is provided with a connecting cavity 110 with a lower opening, and the cooking cover 20 is provided with a connecting part 210. The connecting part 210 is detachably connected to the connecting cavity 110 and the connecting part 210 is movable up and down relative to the connecting cavity 110. The variable signal converter 40 is fixedly disposed in the connecting cavity 110, and the sensing end 410 is drivenly connected to the connecting part 210. The connecting part 210 moves up and down relative to the connecting cavity 110, synchronously driving the sensing end 410 to slide up and down relative to the sliding rheostat.

[0057] Referring to Figures 3 and 4, in some embodiments, a movable member 530 is provided within the engagement cavity 110. The movable member 530 is vertically movable relative to the engagement cavity 110 and is connected to the sensing end 410. When the movable member 530 moves vertically relative to the engagement cavity 110, it causes the sensing end 410 to slide vertically relative to the sliding rheostat. The engagement cavity 110 is provided with a first elastic element 520, which applies a downward force to the movable member 530. When the main unit 10 moves downward relative to the cooking cover 20, the cooking cover 20 pushes the movable member 530 upward relative to the engagement cavity 110, thereby causing the sensing end 410 to slide upward relative to the sliding rheostat. When the main unit 10 moves upward relative to the cooking cover 20, the first elastic element 520 releases its stored force to push the movable member 530 downward relative to the engagement cavity 110, thereby causing the sensing end 410 to slide downward relative to the sliding rheostat. In this embodiment, the movable member 430 is provided to connect and transmit power with the sensing end 410, thereby improving the stability of the movement of the sensing end 410.

[0058] Referring to Figure 4, the movable part 530 is provided with a guide post 510, and the engagement cavity 110 is provided with a guide hole 540. The guide post 510 is inserted into the guide hole 540 and the two can move up and down relative to each other.

[0061] In the first embodiment of the connection between the main unit 10 and the cooking cover 20: Referring to Figures 5 and 6, the cavity wall of the connecting cavity 110 is provided with a first opening 114 that communicates with the first slide groove 113, and the first slider 220 can be screwed into the first slide groove 113 through the first opening 114; the main unit 10 and the connecting part 210 are provided with an anti-rotation structure to constrain their relative rotation.

The second slider 1150 can be inserted into the second sliding groove 250. When the joint 210 moves up and down relative to the joint cavity 110, the first slider 220 moves in the second sliding groove 250.

[0063] In the second embodiment of the connection between the main unit 10 and the cooking cover 20: Referring to Figures 7 and 8, the outer surface of the joint 210 is provided with a second opening 260 that communicates with the second slide groove 250, and the second slider 115 can be screwed into the second slide groove 250 through the second opening 260; the main unit 10 and the joint 210 are provided with an anti-rotation structure to constrain their relative rotation.

[0064] In some embodiments, the anti-rotation structure includes a positioning protrusion 112 disposed on the cavity wall of the engagement cavity 110, and the engagement portion 210 is provided with a positioning groove 240 that mates with the positioning protrusion 112. The positioning protrusion 112 is engaged into the positioning groove 240, thereby constraining the main unit 10 and the engagement portion 210 to rotate relative to each other, thereby preventing the second slider 115 from disengaging from the second slide groove 250 or the first slider 220 from disengaging from the first slide groove 113.

[0065] In some embodiments, the anti-rotation structure includes a limiting groove 111 disposed on the cavity wall of the engagement cavity 110, and the engagement portion 210 is provided with a limiting portion 230 that cooperates with the limiting groove 111. The limiting portion 230 is engaged in the limiting groove 111, thereby constraining the main unit 10 and the engagement portion 210 to rotate relative to each other, thereby preventing the second slider 115 from disengaging from the second slide groove 250 or the first slider 220 from disengaging from the first slide groove 113.

[0067] Furthermore, the mating cavity 110 is provided with multiple guide posts 150, and the mating platform 120 is sleeved on the guide posts 150 and is movable up and down relative to the guide posts 150. The lower end of the guide post 150 is provided with a limiting member 170 that abuts against and limits the lower surface of the mating platform 120.

[0068] Furthermore, the second elastic element 160 is a spring. The second elastic element 160 is sleeved on the guide post 150, with one end abutting against the fitting platform 120 and the other end abutting against the cavity wall of the engagement cavity 110.

It is used to touch the touch element 610 according to actual needs, so that the menu mainboard 620 feeds back operation information to the control module 130. The control module 130 then enters the corresponding working mode based on the touch information.

[0070] Referring to Figures 2 and 4, the interior of the cooking cover 20 is hollow, forming a cavity 200 with openings at the top and bottom. The rotating shaft 30 is rotatable and movable up and down within the cavity 200. A movable cavity 270 is provided at the upper part of the cooking cover 20, which is connected to the cavity 200.

[0072] Referring to Figure 4, the engagement cavity 110 is provided with a downwardly extending limiting protrusion 100. The limiting protrusion 100 can abut against the moving element 280, thereby restricting the position movement of the rotating shaft 30 to prevent the rotating shaft 30 from damaging the motor during the downward movement of the host 10, thus protecting the motor.

[0073] Referring to Figure 4, the motor 140 is provided with a first coupler 710, and the rotating shaft 30 is provided with a second coupler 720. The first coupler 710 and the second coupler 720 are plugged into each other for coupling.
