Definitions
- the invention relates to a mixer with a stir-in mass or liquid to be stirred agitator, with a drive motor driving the drive motor, with a drive motor enclosing housing and with a fastening point for fixing the mixer in the position of use, especially for laboratory purposes.
- stirrers are known in many forms. Above all, such stirrers for laboratory use are often attached to a tripod, but such stirrers are also known with another associated holder or storage.
- the object to provide a stirrer of the type defined, in which the risk of damage or destruction of parts involved in the stirring parts is reduced or avoided.
- the invention provides that the mixer has an unbalance responsive sensor. This makes it possible to detect occurring vibrations or imbalance on the mixer in good time and provide a remedy.
- An expedient embodiment can consist in that the unbalance-responsive sensor is an acceleration sensor. Acceleration sensors are known per se and can be purchased inexpensively and mounted in a simple manner on or in the stirrer.
- the senor is provided with an audible and / or optical display or signaling device or controls such.
- the user of the mixer can be warned acoustically or visually, if too much imbalance should occur.
- the unbalance-responsive sensor is connected to the control of the drive motor and changes the speed of the drive motor when a limit value is exceeded, namely reduced or increased, or switches off the drive motor.
- the sensor can be arranged on the housing of the stirrer and / or on at least one printed circuit board arranged in the housing, for example on the circuit board serving for the control or regulation of the drive motor and / or on the power supply of the drive motor. This allows the sensor directly into the appropriate circuit be included and connected to this.
- the vibrations which occur as a result of manufacturing tolerances or due to a difficult mixing material are also transferred to the housing, so that the aforementioned arrangement of the sensor on the housing itself can be regarded as a simple and possibly subsequently feasible option for solving the above-described problem.
- Another possibility in this regard, which can be provided in addition to or instead of the above-described possibilities, is that the sensor could be arranged on the holder of the stirring device.
- An expedient embodiment, in particular of the sensor, can provide that it is piezobased or inductively formed with a plunger coil or by means of a deflectable mass or by means of strain gauges. Sensors designed in this way have proved useful in detecting imbalances or vibrations, so that a corresponding use for the stirring device according to the invention represents an inexpensive solution.
- FIG. 1 is a front view
- Fig. 2 is a partially longitudinal sectioned side view
- Fig. 3 is a rear view
- Fig. 4 is a plan view of a stirring device according to the invention with a not shown or not hitched agitator driving drive motor.
- An agitator is intended to be stirred with a stirring tool that can be introduced into a mass or liquid.
- the stirring tool can be coupled with a chuck 2, which in turn is connected via a shaft 3 with a drive motor 4, so that after inserting a stirring tool in the chuck 2 by switching this drive motor 4 can be stirred.
- the drive motor 4 is housed in a housing 5 enclosing it, on which outside an attachment point 6 is provided for fixing the stirring device 1 in the position of use. It can be seen in the embodiment of the rear wall 7 of the housing 5 as an attachment point 6 a provided with a mounting screw 8 console 9, which allows plugging the mixer 1 with this attachment point 6 on a horizontal arm 61 of a tripod.
- an unbalance-responsive sensor 11 or a vibration sensor 11 is provided on a printed circuit board 10 arranged in the housing 5 of the agitator 1 according to FIG. This can be arranged at the serving for the control or regulation of the drive motor 4 or on a serving for the power supply of the drive motor 4 circuit board 10 and integrated into the circuit.
- On the rear wall 7 can be seen still an interface 12 and a cable 13 for the power or power supply, and also inside lines 14 to the circuit board 10th
- the sensor 11 may be piezobased or inductively formed with a plunger coil or by means of a deflectable mass or by means of strain gauges and, for example, be commercially available. It should be mentioned that, if appropriate, more than one sensor 11 could also be provided.
- the agitator 1 with a stir-in to be stirred mass or liquid agitator, with a stirring tool driving drive motor 4, with a drive motor 4 enclosing the housing 5 and with an attachment point 6 for fixing the agitator 1 in the use position has at least one on imbalance responsive sensor 11, which is preferably connected to the control or regulation of the drive motor 4 or interconnected and unwanted or dangerous vibrations or vibration Turn off the drive motor 4 or can change its speed.
