Description

Homogeneous mixer control mechanism

This creation relates to the field of homogenizers, in particular to a control mechanism that operates an agitator of the homogenizer to perform food processing homogenization.

The homogenization process referred to here usually refers to the operation process of two or more incompatible components into a stable and uniform liquid suspension. Therefore, the described homogenizer (Homogenizer) prepares a mechanical device for uniformly mixing a variety of fines.

The known homogenizer has a machine table which supports a shell to maintain a certain height. One end of a shaft is equipped with a stirrer, and the other end is connected with an electric motor through the shell, and the electric motor drives the shaft to drive the stirrer to rotate in the same direction. An inductor and an electric motor are electrically connected to a control circuit, and are installed in the housing together. The sensor detects the rotation speed of the electric motor and outputs a signal to the control circuit. The control circuit compensates for the rotation kinetic energy of the electric motor, so that the shaft drives the agitator to maintain a constant rotation speed to achieve uniform mixing.

The operating mode of the homogenizer distinguishes between wireless and wired. In terms of wireless operation, using the principle of infrared transmission and reception, a remote control is used to control the speed of rotation of the stirrer by a remote control electric motor. In terms of wired operation, two ends of a wire are connected to a controller and a USB connector plugged into the homogenizer, and the controller operates the speed of the stirrer.

However, the homogenizer does not have a preset function, and can only use the accelerator button of the remote control (or controller) to control the electric motor to increase the speed. Furthermore, through the stop button of the remote control (or controller), you can choose to stop the electric motor or reduce the speed of the electric motor by the deceleration button.

Therefore, how to improve the operating mode of the homogenizer has become an urgent issue for this creation.

In view of this, the author of this case proposed a new control mechanism. The main purpose is to use a pre-set mechanism to connect electronic components with a printed circuit board (PCB), and match the shuttle knobs, buttons and other mechanical structures. Set the speed and operating time, so that the homogenizer can automatically perform the homogenization process of food processing.

To achieve the above purpose, the homogenizer of this creation uses a column to connect to a shell. One end of a shaft penetrates into the shell, and the other end is combined with a stirrer. The homogenizer is equipped with a control mechanism for operating the stirrer, and the control mechanism includes: a fixing seat is arranged on the outside of the column and facing the shaft; a control panel is arranged on the housing, and the control panel includes:

A display area showing the rotation speed and mixing time; a group of light signal areas showing automatic and manual modes; and an adjusting knob and a button for changing the rotation speed, mixing time, and setting value of the automatic or manual mode.

In this way, the control mechanism of this creation uses knobs and buttons to preset the rotation speed and mixing time of the homogenizer. With the design of the printed circuit board connected to the electronic components, the homogenizer can adopt one of the automatic or manual modes according to the user's wishes. , Perform homogenization of food processing.

In order to make the purpose, features and advantages of this creation more simple and understandable, one or more embodiments are given below in detail with the accompanying drawings.

Figure 1 is a perspective view showing a preferred embodiment of a homogenizer 10. In the figure, a container 90 like a cup is used with the homogenizer 10.

Wherein, the homogenizer 10 has a column 11, one end of the column 11 is connected to a base 12, and the other end is connected to a shell 13. When the base 12 is placed on a supporting surface (such as a desktop), the column 11 supports the housing 13 to maintain a certain height with the supporting surface. A power cord 14 is partially buried in the homogenizer 10. The end of the power cord 14 exposed to the homogenizer 10 is connected to a plug 15, which is combined with an external socket (not shown) to supply the power required by the homogenizer 10 . A fixed seat 16 is locked on the outside of the column 11. The opposite side of the fixed seat 16 is a shaft 17. One end of the shaft 17 penetrates into the housing 13, and the other end is combined with a stirrer 18.

In addition, a power switch 19 is installed on the side of the casing 13, and the power switch 19 determines whether the power cord 14 supplies power to the homogenizer 10 or not. A control panel 20 is embedded in the front of the housing 13. Above the control panel 20 is a display area 21 and a group of light signal areas 22. A jog dial 23 is installed below the control panel 20, and a button 24 is assembled in the center of the knob 23.

Figure 2 is a front view showing the front of the control panel 20. In the figure, the display area 21 has two sets of numbers. The number on the left of the display area 21 represents the number of rotation speed 21A, and the number on the right represents the stirring time 21B.

The group of light signal areas 22 are on both sides of the control panel 20. During the power outage, the group of lights 22 is off. After power on, the automatic light 22A on the left will light up, which means that the current state of the homogenizer belongs to the automatic operation mode. On the contrary, the manual light 22B on the right is on, which means the homogenizer is currently in manual operation mode.

Furthermore, the knob 23 rotates in the direction of the arrow 23A, which has an incremental function of numbers. On the contrary, the knob 23 rotates in the direction of the arrow 23B to select the decreasing number. Therefore, the knob 23 can change the set value of the speed and time.

In some embodiments, two sets of patterns replace numbers and appear in the display area 21. The set of patterns can be a ring pattern surrounded by multiple squares, or a single rectangular pattern, which is also within the allowable range of this creation.

Figure 3 is a perspective view showing the internal structure of the homogenizer 10 and describing in detail the components (parts) protected by the housing 13. In the figure, there is a connecting piece 25 inside the housing 13, the connecting piece 25 is fixed, and is connected to a printed circuit board (PCB) 26 through a latch structure, and the printed circuit board 26 is behind the control panel 20.

As shown in FIG. 4, the printed circuit board 26 includes metal conductors as lines for connecting electronic components. The electronic components referred to here generally refer to the known counter 27, light emitting diode (Light Emitting Diode, abbreviated as LED) 28, encoder 29, microprocessor, active component, passive component, resistor, capacitor or other The components are recombined to give new functions through the circuit.

Wherein, the counter 27 faces the display area of the control panel 20. The light-emitting diode 28 faces one of the automatic light signal or the manual light signal in the group of light signal areas. An operating rod 29A is connected to the button and/or knob at one end, and the encoder 29 is inserted into the other end.

The encoder 29 has a grating or voltage structure, which converts the torque of the knob or the pressure of the button into a signal and outputs it to the microprocessor. According to the software programming, the microprocessor changes the number of the counter 27, or determines that a single light-emitting diode 28 emits light.

Looking back at Figure 3, a set of frame 30, an electric motor (not shown), two shock-proof blocks 31, an induction IC board 32 and a micro switch 34 are installed in the housing 13. The frame body 30 is separated by a certain distance, and is connected to the part where the shaft 17 is inserted into the housing 13 through a bearing mode. The electric motor is connected to the shaft 17 to drive the agitator to rotate relative to the housing 13. The anti-vibration block 31 is located between the frame 30 and the housing 13 and absorbs vibration energy generated by the rotation of the shaft 17. The sensing IC board 32 belongs to the category of Integrated Circuit (IC), which is detected by a magnet 33 of the shaft 17, and obtains the signal of the rotation speed of the shaft 17 driven by the electric motor and feeds it back to the microprocessor. Determine whether the speed of the electric motor has changed. The micro switch 34 is fixed and has a touch piece 35, the free end of the touch piece 35 is close to a hook piece 16A of the fixing base 16.

Figure 5 is a partial perspective view showing the container 90 hung on the hook piece 16A. The edge 95 of the container 90 presses the touch plate 35 to swing toward the micro switch 34, and drives a floating point 36 of the micro switch 34 to move, causing the micro switch 34 to output a signal to the microprocessor. At this moment, the micro switch 34 is turned on to notify the microprocessor of the current state of use of the homogenizer.

Based on the above description, it is not difficult to understand that the homogenizer in this embodiment is a machine or equipment that can be programmed. Next, using the homogenizer 10 of FIG. 1 and the flow of FIG. 6 to describe the specific operation process in detail.

In the step 80 of "starting the switch", a user (not shown) turns on the power switch 19 to ensure that the power cord 14 continues to supply the power required by the homogenizer 10.

The user presses and hold the button 24 for a certain period of time (for example, two seconds) to directly enter the setting mode. If necessary, the user has to "skip" 81 setting mode and enter the program of "select mixing mode" 85 directly. The setting mode includes two steps: "time setting" 82 and "rotating speed setting" 83.

In the "time setting" 82 step, the user uses the knob 23 to change the stirring time. Among them, the maximum value of the flashing number in the display area 21 is 99, and the minimum value is 00. Of course, the mixing time cannot be 0, so 01~99 is the effective adjustment range.

In step 83 of "speed setting", the user presses the button 24 once to enter the adjustment mode of the electric motor rotation speed. At this moment, the maximum value of the flickering number in the display area 21 is 6, and the minimum value is 1, which represents the level of rotation speed. Among them, the first-level rotation is the slowest, and the sixth-level rotation is the fastest. Because the number of stages is small, turn the knob 23 slowly.

When the user presses the button 24 again, the microprocessor stores the data, and the program of "end setting mode" 84.

Generally, the mixing operation of the homogenizer 10 is set in the automatic mode. If the user continuously presses the button 24 several times (for example, three times), he can choose to manually operate the homogenizer 10 to complete the step 85 of "Selecting the Stirring Mode". Of course, if the user continuously presses the button 24 several times again, the manual mode will return to the automatic mode. At this moment, the light area 22 displays the current stirring mode of the homogenizer 10.

In the "automatic stirring" 86 step, the user holds the container 90 from the bottom up to receive the stirrer 18 and the partial shaft 17 until the edge 95 of the container 90 is hung on the hook piece 16A, and at the same time, the micro switch 34 is pressed. Slice 35 (refer to Figure 5). The micro switch is the key of the automatic mode, and the homogenizer 10 is started to automatically perform the mixing operation according to the above-mentioned rotation speed setting value.

When the time setting value expires, the agitator 18 will no longer operate, and the step of "agitating stop" 88 is completed. At this moment, the user removes the container 90, hangs the fixing seat 16 with other containers 90, and enters the cycle of two steps of "automatic stirring" 86 and "stirring stop" 88 again. Alternatively, the user turns off the power switch 19 to interrupt the power supply, and completes the step 89 of "turn off the switch".

In the step 87 of "manual stirring", although the container 90 also receives the stirrer 18 and the partial shaft 17 from bottom to top, the hook piece 16A is hung with the edge 95 and the touch piece 35 is pressed (refer to Figure 5). However, the key to starting the manual mode is not a micro switch, so the homogenizer 10 will not operate. At this moment, when the user presses the button 24, the homogenizer 10 will perform the mixing operation. If the user presses the button 24 again, the homogenizer 10 will stop running. When the button 24 is pressed for the third time, the homogenizer 10 continues to stir until the time set value expires, the stirrer 18 does not run anymore, and the step of "stirring stop" 88 is completed.

After the container 90 is removed, the user hangs the fixing seat 16 with another container 90 and presses the button 24 again, and the homogenizer 10 enters the cycle of two steps of "manual stirring" 87 and "stirring stop" 88. Of course, the user can also enter step 89 of "turn off the switch" and turn off the power switch 19 to interrupt the power supply.

In particular, in the step of "automatic stirring" 86 or "manual stirring" 87, the user can arbitrarily change the speed of the stirrer 18 with the knob 23, but will not change the setting value of the homogenizer 10 regarding the speed. In other words, the speed of this rotation can only affect a single cycle (whether it is "automatic stirring" 86 to "stirring stop" 88, or "manual stirring" 87 to "stirring stop" 88) cycle, the next cycle is still The setting value of the homogenizer 10 is used to perform the mixing operation.
