Disclosed are a magnetic levitation device and a linear motion mechanism thereof. The magnetic levitation device is provided with a base and a levitation body, the base comprises a first magnetic assembly, the levitation body comprises a second magnetic assembly, and the first magnetic assembly and the second magnetic assembly are configured to be capable of providing a magnetic balance force required when the levitation body stably levitates relative to the base. The linear motion mechanism is arranged in the base, and comprises: a threaded column installed in a non-displaceable manner relative to the base, wherein at least one part of the threaded column in the length direction of the threaded column is provided with threads; and a displacement support used for supporting the first magnetic assembly of the base, wherein the displacement support is provided with a threaded portion matching the threads of the threaded column, such that when the threaded portion of the displacement support rotates relative to the threaded column, the displacement support generates a corresponding displacement in the length direction of the threaded column. According to the magnetic levitation device, due to the fact that the linear motion mechanism that is simple in structure and reasonable in space layout is used in the base, the whole base is more compact and more reliable in performance.

The present invention provides a method for positioning a suspension body and a magnetic suspension device using the method. The method comprises the following steps: step 1, providing a positioning auxiliary forming a channel for the suspension body to enter and rotate therein; step 2, placing the positioning auxiliary on a magnetic suspension base, and a center line of the channel of the positioning auxiliary being substantially collinear with a center line of the rotation of the suspension body at work; step 3, according to the channel of the positioning auxiliary, placing the suspension body at the top of the positioning auxiliary; step 4, releasing the suspension body to make it voluntarily slide down to a position to be suspended to work; step 5, removing the positioning auxiliary. The present invention can make the suspension body quickly slide down to be suspended at its work position by means of the positioning auxiliary, and so make the suspension body suspended normally, thereby greatly increasing the use efficiency.

A magnetic suspension device comprises a magnetic base and a suspension body. The suspension body is suspended above the magnetic base. The suspension body is provided with a receiving coil and at least one luminous body. The magnetic base is provided with a transmitting coil. The transmitting coil transmits an AC signal to the receiving coil. The receiving coil converts the AC signal transmitted by the transmitting coil into electric energy and supplies the electric energy to the luminous body for emitting light. In the magnetic suspension device of the present invention, the transmitting coil is arranged at the magnetic base, and the receiving coil is arranged in the suspension body. Wireless power transmission is realized through the transmitting coil and the receiving coil, so, the luminous body arranged on the suspension body can emit light without any cell and external power supply. This wireless power transmission method can avoid the impact on the operation of the suspension body, which not only can ensure the favorable suspension effect of the suspension body, but also can make the suspension body emit light. The magnetic suspension device has a very good decorative effect, and can be widely used in fields such as toys, ornaments, advertisements, and so on.

The present invention discloses a liquid volumetric device comprising a metering tube, a start sensor, an end sensor, a bath for storage of a sample to be metered, a vacuum chamber and a pump for pumping out air inside the vacuum chamber to form a negative pressure inside the vacuum chamber. The start sensor and the end sensor are provided respectively at the bottom and the top of the metering tube, the top of the metering tube is in communication respectively with the vacuum chamber and the outside atmosphere via pipelines, the bottom of the metering tube is in communication respectively with the bath and the vacuum chamber via pipelines, and control parts are provided in each of the pipelines for controlling connection/disconnection thereof. Thus, by forming a negative pressure inside the vacuum chamber, a sample in the bath may be pressed from down to up into the metering tube by means of a pressure difference between the atmosphere and the negative pressure, so as to complete the volume metering, whereby an occurrence of the side flow phenomenon can be completely eliminated.
