Description

Technical Field

[0001] This utility model relates to a mixer, and more particularly to a mixer control mechanism and a mixer. Background Technology

[0002] As people's living standards improve, household blenders are becoming more and more widely used, such as fruit juicers, soy milk makers, household meat grinders, and cassava blenders. Their basic principle is to use a motor to drive the blades to rotate at high speed. The blades cut and blend fruits, beans, meat, and cassava to make them fine and produce juice, pulp, or puree at the same time.

[0003] Current mixers, such as cassava mixers, generally do not have a preheating function. That is, they start mixing cassava directly after the switch is turned on. The temperature of the cassava depends solely on the heat generated during the mixing process. This results in the cassava in contact with the blades being at a higher temperature and the cassava not in contact with the blades being at a lower temperature. The cassava is heated unevenly, and the mixing effect is not ideal. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention employs a method of preheating cassava before stirring, setting the mixer's operation in two stages: In the first stage, a timer starts counting down, sending a signal to the controller. The controller then activates the heating element to preheat the cassava in the pot. In the second stage, when the turntable touches the stirring switch, the switch sends a signal to the controller, which in turn activates the drive assembly. This drive assembly rotates the blade assembly, stirring the cassava in the pot. Simultaneously, the heating element continues to operate.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] Example 1

[0032] like Figures 2-3 As shown, a mixer control mechanism includes a housing 1, a knob 11, a timer 12, a drive assembly 13, a turntable 14, and a stirring switch 15. The top of the housing 1 has a mounting hole. The knob 11 is rotatably mounted within the mounting hole. The timer 12 is connected to the knob 11. The turntable 14 rotates coaxially with the knob 11 and is in movable contact with the switching part of the stirring switch 15. The control mechanism controls the mixer to perform heating and stirring. The drive assembly 13 can be a motor and a reduction gear set, with the reduction gear set mounted on the output shaft of the motor.

[0033] In this embodiment, after turning knob 11 to start the mixer, the working state of the mixer is divided into two stages;

[0034] The first stage is when timer 12 starts counting down and sends a signal to the controller, which then controls the heating plate of the mixer to preheat the cassava in the pot 3.

[0035] In the second stage, when the turntable 14 touches the switch of the stirring switch 15, the stirring switch 15 sends a signal to the controller, and the controller controls the drive component 13 to start working. The drive component 13 drives the blade assembly 5 to rotate and stir the cassava in the pot 3. At the same time, the heating plate continues to work.

[0036] Throughout the entire countdown of timer 12, the heating element remains operational.

[0037] This invention involves preheating the cassava before stirring. Heating the cassava reduces its viscosity, making the stirring process easier and more efficient compared to stirring directly. Furthermore, it allows for more even heat distribution, ensuring the cassava is heated and expands uniformly, thus improving the homogeneity of the cassava mixture.

[0038] like Figure 4 , Figure 5 As shown, the preferred turntable 14 has a fan-shaped structure.

[0039] Since the turntable 14 rotates coaxially with the knob 11, the turntable 14 is set as a fan-shaped structure. When the turntable 14 touches the switch part of the stirring switch 15, pressure is applied to the switch part, turning on the stirring switch 15. The stirring switch 15 sends a signal to the controller, and the controller controls the drive component 13 to start working. During the entire rotation of the turntable 14, the switch part is subjected to continuous pressure, and the stirring switch 15 is always in the open state, continuously stirring the cassava. When the turntable 14 is completely displaced from the switch part of the stirring switch 15, the pressure applied to the switch part disappears, the drive component 13 stops working, the stirring ends, and at the same time, the timer 12 ends, and the heating plate stops heating.

[0040] like Figure 3 As shown, it also includes a fixed bracket 16, which is fixed inside the housing 1. The turntable 14 rotates against the end face of the fixed bracket 16. The stirring switch 15 is fixed to the bottom of the fixed bracket 16, and the timer 12 is located below the fixed bracket 16. The fixed bracket 16 supports the stirring switch 15, the turntable 14, and the timer 12. A switch through hole 161 is provided at the position corresponding to the stirring switch 15 on the fixed bracket 16. The switching part of the stirring switch 15 extends out of the switch through hole 161, so that the turntable 14 can touch the switching part during rotation. The switching part of the stirring switch 15 is... Figure 6 The raised part in the middle fixes the stirring switch 15 to the bottom of the fixed bracket 16, which can make more reasonable use of space.

[0041] In this embodiment, the turntable 14 rotates from one side of the stirring switch 15 toward the stirring switch 15. When the turntable 14 touches the switch part of the stirring switch 15, the stirring switch 15 is turned on. During the rotation of the turntable 14, pressure is continuously applied to the switch part, and the stirring switch 15 is always in the open state. After receiving the signal to start stirring, the controller controls the drive component 13 to work. When the turntable 14 is completely displaced from the switch part of the stirring switch 15, the pressure applied to the switch part disappears, the stirring switch 15 is turned off, and the drive component 13 stops working.

[0042] like Figure 4 , Figure 5 As shown, a through cavity can be opened in the fan-shaped structure.

[0043] The through-cavity reduces the weight of the turntable 14 and saves energy. Since the curved edge of the turntable 14 contacts the switch part of the stirring switch 15, the through-cavity will not affect the opening and closing of the stirring switch 15.

[0044] like Figure 7 As shown, a mounting base 111 is provided in the middle of the knob 11, and a mounting cavity 112 with one end open is formed in the mounting base 111, such as... Figure 4 , Figure 5 As shown, a mounting rod 141 and a limiting seat 142 are fixed on opposite end faces of the turntable 14. The mounting rod 141 and the limiting seat 142 are coaxially arranged. The mounting rod 141 is inserted into the mounting cavity 112 and fixed. A first through hole 162 is provided on the fixing bracket 16. The limiting seat 142 passes through the first through hole 162 and is fixed to the connecting shaft of the timer 12. The limiting seat 142 can rotate relative to the first through hole 162.

[0045] In this embodiment, the connecting shaft of the timer 12, the limiting seat 142, the mounting rod 141, the rotating shaft of the turntable 14, and the rotating shaft of the knob 11 are coaxially arranged. During the rotation of the knob 11, the timer 12 starts the countdown at the same time, and the turntable 14 starts to rotate.

[0046] like Figure 4 As shown, a limit block 143 is provided on one side of the rotation axis of the turntable 14 in the vertical direction, such as... Figure 7 As shown, a limiting groove 113 communicating with the mounting cavity 112 is provided on the side wall of the mounting base 111, and a limiting block 143 is inserted into the limiting groove 113 for fixation. By setting the limiting block 143 and the limiting groove 113, the structure of the turntable 14 and the knob 11 after assembly is made more stable, and the phenomenon of the knob 11 rotating relative to the turntable 14 is avoided.

[0047] Example 2

[0048] like Figure 1 , Figure 2As shown, a mixer includes a control mechanism, a base 2, a pot body 3, a pot lid 4, and a blade assembly 5. A heating plate is fixed inside the base 2, preferably fixed to the end face of the base 2. The pot body 3 is placed above the base 2, and the pot lid 4 is movably disposed on the top of the pot body 3. A housing 1 and a drive assembly 13 are respectively fixed on the pot lid 4. The blade assembly 5 is placed inside the pot body 3 and is connected to the drive end of the drive assembly 13. The base 2 has symmetrical first mounting openings on both sides, and the pot lid 4 has symmetrical second mounting openings on both sides. Pot handles 7 are also symmetrically disposed on both sides of the pot body 3. The first and second mounting openings on the same side are connected by the pot handles 7. A housing handle 6 is disposed on one side of the housing 1. A first connector socket is disposed at the bottom of the housing handle 6, and a second connector socket is disposed at the top of one of the pot handles 7. The first and second connector sockets are movably connected.

[0049] After the mixer is assembled, a connected circuit is formed between the housing handle 6, the pot handle 7, and the base 2, with the base 2 connected to an external power source. The control mechanism controls the rotation of the blade assembly 5, thereby mixing the cassava inside the pot 3.

[0050] The pot lid 4 can be removed for cleaning. A first sealing ring is provided at the connection between the drive assembly 13 and the pot lid 4, and the first sealing ring is interference-fitted with the drive assembly 4. A second sealing ring is provided at the connection between the pot lid 4 and the pot body 3, and the second sealing ring is interference-fitted with the pot lid 4. The first and second sealing rings can be made of silicone.

[0051] When the drive assembly 13 and the pot lid 4 are assembled, the first sealing ring prevents water vapor from entering the drive assembly 13 from the connection point, thus preventing the control mechanism from being damaged by moisture. When the pot lid 4 and the pot body 3 are assembled, the second sealing ring prevents water vapor from overflowing from the connection point between the pot lid 4 and the pot body 3, so as to better stir the cassava.

[0052] like Figure 2 As shown, the blade assembly 5 includes a connecting shaft and blades. The blades are distributed at one end of the connecting shaft, and the other end of the connecting shaft is connected to the drive end of the drive assembly 13. Preferably, the edges of the blades are bent upwards to form a bent portion. Since the space at the bottom of the pot body 3 is limited, setting the bent portion can increase the contact area between the blades and the cassava, thereby improving the stirring efficiency.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
