Fig. 3 is a schematic left-hand view of a part of the structure of the magnetocaloric effect demonstration apparatus of the present utility model. Fig. 4 is a right-side schematic view of a part of the structure of the magnetocaloric effect demonstration apparatus of the present utility model.
Referring to fig. 1 to 4, an embodiment of the present utility model provides a magneto-caloric effect demonstration apparatus, comprising: the magnetic field system 1, the first flange ring 11, the second flange ring 12, the first sample 2, the second sample 3, the sample rod 4, the slide 41 movable along a fixed track (not labeled), the drive mechanism 42, the instrument panel 5, the display screen 6, the first color light bar 71, the second color light bar 72, the third color light bar 73, the fourth color light bar 74, the non-transparent housing and the triggering element 9.
The housing of the magnetocaloric effect demonstration apparatus is divided into an upper housing (not labeled) and a lower housing 8. The upper shell is a transparent shell. The upper housing is for example entirely made of transparent material or partly made of transparent material. The transparent area of the upper housing is at least capable of allowing a user to view the magnetic field areas created by the first sample 2 and the second sample 3 entering and exiting the magnetic field system 1 and view the dashboard 5 and the display screen 6. The lower housing 8 is non-transparent and some electrical components (e.g., including a power source, controller, etc., not shown) are disposed within the lower housing 8 that are not required to be viewed by a user.
Specifically, the magnetic field system 1 is a ring-shaped permanent magnet. The magnetic field area of the annular permanent magnet is mainly concentrated in the hollow area of the annular permanent magnet. The first sample 2 and the second sample 3 enter and exit the hollow region of the ring-shaped permanent magnet, thereby entering or exiting the magnetic field environment.
The first flange ring 11 and the second flange ring 12 are provided on both end surfaces of the ring-shaped permanent magnet, respectively. The first flange ring 11 and the second flange ring 12 are formed of, for example, an acryl material.
The magnetocaloric properties of each sample were different. The first sample 2 is for example a positive magnetocaloric effect sample and the second sample 3 is for example a negative magnetocaloric effect sample. The first sample 2 and the second sample 3 are again, for example, a positive magnetocaloric effect sample and a non-magnetocaloric effect sample, respectively. The number of samples is not limited to 2. For example, the number of the samples is 3, namely a positive magnetocaloric effect sample, a negative magnetocaloric effect sample and a non-magnetocaloric effect sample.
In other embodiments the magnetic field system 1 may be U-shaped or any other shape.
The sample rod 4 is formed of a transparent material and is hollow in the inside. The sample rod 4 is, for example, cylindrical with both ends open. The first sample 2 and the second sample 3 are fixed at the same side end within the sample rod 4, and the sample rod 4 moves axially along the same, so that the first sample 2 and the second sample 3 move in and out of the magnetic field environment with the axial movement of the sample rod 4.
In other embodiments, the sample rod 4 is cylindrical, and the first sample 2 and the second sample 3 are fixed at the surface of the same side end region of the sample rod 4.
The sample rod 4, the slide 41 and the drive mechanism 42 constitute a drive system.
Referring to fig. 3, a first color light bar 71 and a second color light bar 72 are provided on a side surface of the first flange ring 11 facing away from the second flange ring 12. The first color light bar 71 is for example shaped as letter N and the second color light bar 72 is for example shaped as letter S. The presence of a magnetic field in the vicinity of the user is prompted in a striking manner.
Referring to fig. 4, a first color light bar 71 and a second color light bar 72 (hidden) are provided on a side surface of the second flange ring 12 facing away from the first flange ring 11. The first color light bar 71 is for example shaped as letter N and the second color light bar 72 is for example shaped as letter S.
The sample rod 4 is fixedly connected with the slide block 41, and the extending direction of the sample rod 4 is the same as the extending direction of the fixed track where the slide block 41 is located. The slider 41 is connected to a driving mechanism 42. The drive structure comprises, for example, a motor. The driving mechanism 42 drives the sliding block 41 to move on the fixed track, and then the sliding block 41 drives the sample rod 4 to axially move along the sliding block, so that the sample rod 41 drives the first sample 2 and the second sample 3 to enter and exit the magnetic field environment.
A temperature sensor (not shown) is provided near each of the first sample 2 and the second sample 3. The temperature sensor is electrically connected to the detecting instrument by a wire (not shown). Only the instrument panel 5 of the detection instrument is marked in the drawing. The temperature values of the first sample 2 and the second sample 3 are displayed on the instrument panel 5.
A display screen 6 is fixed in the housing, the display screen 6 for example being able to display the function of the magnetocaloric effect demonstration device and the method of use. In front view, the display screen 6 is located above the slider 41. The display screen 6 is part of an announcement display system, which also includes, for example, a memory (not shown) storing announcement information, a driving chip (not shown) driving the display screen 6, and the like.
Third color light bars 73 are arranged at the frame positions of the left side face and the right side face of the shell (outside the frame area below the shell), and the third color light bars 73 extend along the frame of the shell, so that the magnetocaloric effect demonstration device is more striking.
The magneto-caloric effect demonstration apparatus further includes a fourth color light bar 74 surrounding the outer circumferential surface of the first flange ring 11 and a fourth color light bar 74 surrounding the outer circumferential surface of the second flange ring 12.
An inductive triggering element 9 is arranged on the inner side surface of the transparent area of the housing. When the user touches the housing near the trigger element 9 with his finger, the trigger element 9 activates the driving mechanism 42, and the driving mechanism 42 drives the slide 41 to move, thereby driving the sample rod 4 to move, so that the first sample 2 and the second sample 3 at the ends of the sample rod 4 enter and exit the magnetic field environment. The user can see the changes of the first sample 2 and the second sample 3 on the dashboard 5 and can see the dynamic process of the first sample 2 and the second sample 3 into and out of the magnetic field environment at the same time.
The side surfaces of the upper case in this embodiment are formed of transparent glass. The top glass is inclined downwards in a direction towards the user, which is more advantageous for the user to observe the various structures inside the upper housing from the inclined top glass.
The device visually and prominently displays the magnetocaloric effect to the user. At least the magnetic field system 1, the first sample 2, the second sample 3 and the instrument panel 5 of the detection instrument are visible in the device.
The embodiments of the present utility model are described in a progressive manner, and the same and similar parts of the embodiments are all referred to each other, and each embodiment is mainly described in the differences from the other embodiments.
The scope of the present utility model is not limited to the above-described embodiments, and it is apparent that various modifications and variations can be made to the present utility model by those skilled in the art without departing from the scope and spirit of the utility model. It is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
