Description

Technical Field

[0001] The utility model relates to a new type of handheld mixer. Background Art

[0002] The prior art, such as the Chinese utility model patent document with the publication number CN115281542A, discloses a hand-held mixer. The key points of its technical solution include a main machine mechanism, a housing, and a tube body connected to the housing. The kit is snap-fitted with the transmission member, so that when the outer shell is separated from the housing, the kit can be separated from the transmission member, enabling the main machine mechanism to be connected to other output structures, such as a whisk. The rotation speed of the motor is adjusted by the control unit to meet the rotation speed requirements of different output structures. The spiral groove is arranged outside the sleeve, and the sleeve is arranged inside the tube body, so that the length of the sleeve can be designed as required, expanding the lifting distance range of the shaft body, and realizing the lifting while the shaft body rotates.

The problem with this driving method of the shaft body is that the movement of the shaft body is related to the rotation. When the cutter head connected to the shaft body is restricted by the material and cannot move, the rotation of the shaft body will also be restricted by the transmission structure and cannot rotate, resulting in the cutter head being unable to solve the problem of immobility through agitation, and further improvement is needed.

[0032] The present invention will be further described below with reference to the drawings and embodiments.

[0033] See Figures 1 - 6 , a new type of hand-held mixer, including a main machine assembly 10 and a stirring assembly 20, the main machine assembly 10 at least includes a housing 100, a driving motor 110 and a control board 101 arranged in the housing 100, the stirring assembly 20 at least includes a stirring cover 200 and a shaft body 210 arranged in the stirring cover 200, the shaft body 210 rotates relative to the stirring cover 200 and is movably arranged along the axis direction of the shaft body 210;

[0034] A first coupler 310 is arranged on the motor shaft 120 of the driving motor 110, and a second coupler 320 coupled and driven with the first coupler 310 is arranged at the upper end of the shaft body 210;

[0035] An electric drive assembly 40 and a variable signal conversion element 50 electrically connected to the control board 101 are arranged on the main machine assembly 10;

[0036] The electric drive assembly 40 is configured to drive the first coupler 310 to move relative to the stirring cover 200 along the axis direction of the motor shaft 120;

[0037] The variable signal conversion element 50 changes the output electrical signal as it moves along the axis direction of the shaft body 210;

[0038] The control board 101 controls the rotational speed of the drive motor 110 according to the electrical signal output by the variable signal conversion element 50.

[0039] In the above embodiment, the drive motor 110 is used to drive the rotation of the shaft body 210, and the electric drive assembly 40 is used to drive the movement of the first coupler 310, thereby driving the movement of the shaft body 210. This enables the rotation and movement of the shaft body 210 to be independent of each other, without mutual interference, and avoids the situation where the shaft body cannot rotate when it cannot move.

[0040] See Figure 6 , during a complete whipping process, it is composed of multiple descending strokes 80 and multiple ascending strokes alternating in sequence.

[0041] Furthermore, in the above embodiment, as the shaft body 210 moves, the variable signal conversion element 50 changes the output electrical signal, and the control board 101 controls the rotational speed of the drive motor 110 according to the electrical signal output by the variable signal conversion element 50. This is to achieve controlling its rotational speed when the shaft body 210 moves, fully whipping the material through speed changes, and avoiding or getting rid of the problem of jamming with the material by adjusting the rotational speed of the shaft body.

[0042] See Figure 6 , during the process of the electric drive assembly 40 being powered on to powered off, the shaft body 210 executes a descending stroke 80;

[0043] During a descending stroke 80, as the shaft body 210 gradually moves downward, the output rotational speed of the drive motor 110 gradually changes.

[0044] Furthermore, during a descending stroke 80, the control board 101 is used to detect the real-time power of the drive motor 110, and as the shaft body 210 gradually moves downward, the real-time power of the drive motor 110 gradually changes;

[0045] During a descending stroke 80, when the real-time power of the drive motor 110 does not gradually change during this descending stroke 80, the control board 101 determines that there is an abnormal movement of the shaft body 210;

[0046] When the shaft body 210 has abnormal movement, the control board 101 enters a preset mode, and the control board 101 controls the drive motor 110 to increase the output speed of the drive motor 110 to a preset speed.

[0047] In the above embodiment, as the shaft body 210 gradually moves downward, the output speed of the drive motor 110 gradually changes, and the gradual change is set to gradually decrease or gradually increase according to different usage requirements. At the same time, according to the increase or decrease of the speed, the real-time power of the drive motor 110 gradually increases or decreases.

[0048] In the above embodiment, it is judged whether the shaft body 210 has abnormal movement according to a downward movement stroke 80. In this solution, as the shaft body 210 moves downward, its rotation speed is higher and its power is also higher. When the shaft body 210 is in a downward movement stroke 80, its power will become higher and higher. When the control board 101 detects that its power does not change accordingly, it is judged that there is abnormal movement in the connecting shaft body 210. At this time, the control board 101 controls the drive motor 110 to increase the speed to a preset speed, so as to improve the stirring ability of the cutter head 70 by increasing the speed and solve the problem that the cutter head 70 cannot move.

[0049] See Figure 2 and Figure 3 As shown in [relevant figure numbers] and [relevant figure numbers], the electric drive assembly 40 includes a magnetic drive member 410 movably arranged along the axis direction of the motor shaft 120. An electromagnetic coil 420 for driving the magnetic drive member 410 to move downward is arranged on the main machine assembly 10, and an abutting portion 411 is arranged on the magnetic drive member 410;

[0050] When the magnetic drive member 410 moves downward, it drives the shaft body 210 to move relative to the stirring cover 200 along the axis direction of the shaft body 210;

[0051] The stirring assembly 20 further includes a second elastic element 630, and the second elastic element 630 is used to apply an upward moving force to the shaft body 210.

[0052] Further, the first coupler 310 is movably arranged relative to the motor shaft 120 along the axis direction of the motor shaft 120;

[0053] The abutting portion 411 abuts against the first coupler 310 and is used to drive the first coupler 310 to move downward.

[0054] Further, the magnetic drive member 410 is arranged inside the electromagnetic coil 420.

[0055] When the electromagnetic coil 420 is energized and de-energized, during the process from energization to de-energization, the shaft body 210 executes a downward stroke 80. The principle is that a downward magnetic force is generated inside the electromagnetic coil 420. Under the action of the magnetic force, the magnetic drive member 410 moves downward relative to the motor shaft 120. Under the action of the abutting portion 411, it pushes the first coupler 310 downward, and the first coupler 310 synchronously pushes the second coupler 320 and the shaft body 210 downward.

[0056] When the electromagnetic coil 420 is de-energized, the magnetic field inside the electromagnetic coil 420 disappears. At this time, the magnetic drive member 410 has no downward acting force, so under the action of the second elastic element 630, it drives the shaft body 210 to reset upward. When the shaft body 210 resets upward, the first coupler 310, the second coupler 320, and the magnetic drive member 410 move upward to reset.

[0057] In the above embodiment, the first coupler 310 is movably arranged along the axis direction of the motor shaft 120 relative to the motor shaft 120. It can realize that during the downward movement of the second coupler 320 driven by the shaft body 210, the first coupler 310 moves synchronously to ensure the contact area between the first coupler 310 and the second coupler 320, thereby ensuring the torque output of the drive motor 110.

[0058] In the above embodiment, the abutting portion 411 has an annular structure, and a linear bearing 430 is installed inside the abutting portion 411. The linear bearing 430 is slidably connected to the motor shaft 120.

[0059] In the present utility model, the magnetic drive member 410 is preferably made of iron.

[0060] In the present utility model, the magnetic drive member 410 is movably arranged inside the housing 100.

[0061] See Figure 3 , a first elastic element for driving the magnetic drive member 410 or the first coupler 310 to reset upward is provided on the host assembly 10. The function of the first elastic element is to drive the magnetic drive member 410 or the first coupler 310 to reset upward.

[0062] In the first embodiment of the above embodiment, the first elastic element includes a first spring 122, and a guide member 121 is connected to the lower end of the motor shaft 120;

[0063] The first coupler 310 includes a plugging cavity 311 and a coupling cavity 312 which are arranged at intervals up and down. The plugging cavity 311 is in plugging fit with the motor shaft 120, and the second coupler 320 is in plugging fit with the coupling cavity 312;

[0064] A guiding hole 313 is provided between the plugging cavity 311 and the coupling cavity 312. The guiding member 121 is plugged into the guiding hole 313 and extends into the coupling cavity 312.

[0065] The first spring 122 is sleeved on the guiding member 121, with its upper end connected to the first coupler 310 and the other end connected to the guiding member 121.

[0066] Further, the guiding member 121 is a bolt, and the bolt head of the bolt is located at the end far from the motor shaft 120. The bolt head has a limiting and constraining effect, and one end of the first spring 122 connected to the guiding member 121 abuts against the bolt head.

[0067] Further, when the first coupler 310 moves downward, the first spring 122 is compressed and stores energy. The magnetic field inside the electromagnetic coil 420 disappears, and the magnetic driving member 410 loses the downward acting force. At this time, the first spring 122 releases the acting force to drive the first coupler 310 to move upward and reset.

[0068] In the above embodiment, for the second embodiment of the first elastic element, it includes a second spring 450 provided in the housing 100. A connecting portion 440 is provided on the magnetic driving member 410. The upper end of the second spring 450 is connected to the connecting portion 440, and the lower end is connected to the housing 100 to provide an upward moving acting force for the magnetic driving member 410. To achieve that when the magnetic driving member 410 moves downward, the second spring 450 is stressed and compressed to store energy. When the electromagnetic coil 420 is powered off, the second spring 450 releases the stored energy to drive the magnetic driving member 410 to move upward and reset.

[0069] See Figure 2 and Figure 3 , the variable signal conversion element 50 is a sliding rheostat, and the sliding rheostat is fixedly arranged on the host assembly 10;

[0070] The sliding induction end 510 of the sliding rheostat is fixedly connected to the magnetic driving member 410 or the first coupler 310.

[0071] During the downward movement of the sliding induction end 510 along with the first coupler 310, the resistance value inside the sliding rheostat changes accordingly, and thus the current passing through the sliding rheostat also changes accordingly. The control board 101 changes the control of the rotational speed of the driving motor 110 according to this signal.

[0072] See Figure 4 , a sliding cavity 220 is provided inside the stirring cover 200. A sliding seat 610 is provided inside the sliding cavity 220. A rotating bearing 620 is provided inside the sliding seat 610. The inner ring of the rotating bearing 620 is connected to the shaft body 210.

[0073] See Figure 2 The abutting portion 411 is provided at the upper end of the magnetic driving member 410, and the lower end of the magnetic driving member 410 extends into the stirring cover 200 and abuts against the upper end surface of the sliding seat 610.

[0074] When the magnetic driving member 410 moves downward, the abutting portion 411 drives the first coupler 310 to move downward, so that the first coupler 310 and the second coupler 320 always maintain a coupled transmission relationship. At the same time, under the action of the abutting between the lower end of the magnetic driving member 410 and the sliding seat 610, it can drive the sliding seat 610 to move downward, thereby driving the shaft body 210 to move downward.

[0075] See Figure 4 A limiting seat 640 is provided in the sliding cavity 220, and the shaft body 210 is inserted into the limiting seat 640; upper limiting elements 660 and lower limiting elements 650 are respectively provided on the shaft body 210 on the upper and lower sides of the limiting seat 640; the second elastic element 630 is a spring and is sleeved on the shaft body 210 between the upper limiting element 660 and the limiting seat 640.

[0076] In the present utility model, the shaft body 210 reciprocates between a first position and a second position along the axial direction. The upper limiting element 660 and the lower limiting element 650 play a role in limiting between the first position and the second position.

[0077] When the shaft body 210 is located at the first position, the upper end surface of the lower limiting element 650 fits with the lower end surface of the limiting seat 640.

[0078] When the shaft body 210 is located at the second position, the lower end surface of the upper limiting element 660 fits with the upper end surface of the limiting seat 640.

[0079] In the present utility model, the stirring cover 200 is assembled with the machine shell 100 by using an existing detachable connection method, such as existing detachable connection structures such as snap fasteners and screw fasteners.

[0080] In the present invention, the stirring cover 200 has a structure with a hollow interior and openings at both the upper and lower ends.
