Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation device technology, and more specifically to a magnetic levitation rotating lamp. Background Technology

[0002] Currently, magnetic levitation devices are appearing more and more frequently, such as magnetic levitation globes, magnetic levitation gifts, and magnetic levitation lamps. This type of magnetic levitation device utilizes the strong magnetism of permanent magnets and the repulsive effect of like magnetic poles to create a levitation effect. Its novel structure attracts customers and has a huge potential market. Chinese patent (CN104390189B) discloses "A Magnetic Levitation Rotating Lamp," which specifically includes a switch, a base, and a levitation body. An electromagnet is installed in the base, and a levitation magnet is installed on the levitation body at a position corresponding to the electromagnet. A hollow column is provided on the base, with smooth protrusions on its outer surface. The levitation body is fitted onto the column and can rise under magnetic force. The base also includes a drive device for rotating a connecting rod, which extends into the cavity of the column. A second magnet is installed on the portion of the connecting rod within the column. When the levitation body is levitated, a third magnet is installed at a position corresponding to the second magnet. A light source is also provided in the column, and a light-transmitting block is located at a position corresponding to the light source. When the levitation body is levitated, it covers the light-transmitting block. The levitation body has a shell with a hollowed-out portion on its outer side, and the side of the shell facing the column is hollowed out or transparent.

[0003] The device has defects in use. For example, when in use, the attraction between the second and third magnets drives the rotation of the connecting rod to rotate the second magnet, which in turn drives the levitated body to rotate through the third magnet. However, when the levitated body falls, the attraction between the second and third magnets can easily interfere with the levitated body's descent. Secondly, this attraction can easily cause the levitated body to deform. Since the levitated body is in contact with the column, when the levitated body deforms, it will affect the levitated body's rise and fall. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a magnetic levitation rotating lamp to solve the problem that the attraction relationship between the second magnet and the third magnet in the above-mentioned background art can easily interfere with the rise and fall of the levitation body.

[0005] This utility model provides the following technical solution: a magnetic levitation rotating lamp, including a base, a cylindrical column connected to the top of the base, a lamp body fixedly installed on the top of the cylindrical column, a levitation body slidably sleeved on the side wall of the cylindrical column, a magnet fixedly connected to the bottom of the inner wall of the levitation body, an electromagnet installed inside the base, a recessed circular groove provided on the top of the levitation body, several through slots opened on the side wall of the cylindrical column, several blades fixedly connected to the inner wall of the recessed circular groove on the top of the levitation body, an air pump installed on the side wall of the base, the air pump being used to draw gas from outside the base and inject it into the base, and several air outlets opened on the top of the base.

[0006] Furthermore, each of the several slots on the side wall of the cylinder is fixedly connected to an air passage box, and each of the air passage boxes is tilted clockwise at more than 30 degrees.

[0007] Furthermore, several of the blades are tilted clockwise at an angle of more than 30 degrees.

[0008] Furthermore, a fixed cover is fixedly connected to the side wall of the base, the air pump is located inside the fixed cover, and several air inlets are provided on the top of the fixed cover.

[0009] Furthermore, a switching valve assembly is provided inside the base. When the electromagnet is energized and generates magnetic force, the switching valve assembly will block the air outlet. When the electromagnet is de-energized and the electromagnetic force disappears, the switching valve assembly will block the cylinder.

[0010] Furthermore, the switching valve assembly includes an inner cylinder, which is fixedly connected to the bottom of the inner wall of the base. An outer cylinder is slidably sleeved on the side wall of the inner cylinder. A top plate is fixedly connected to the top of the side wall of the outer cylinder. A second magnet is fixedly connected to the bottom of the side wall of the outer cylinder. The bottom of the second magnet is connected to the bottom of the inner wall of the base via a tension spring. The inner wall of the outer cylinder is connected to the cylinder column via a linkage valve. The outer cylinder moves downward to control the linkage valve to close, and moves upward to control the linkage valve to close. Both the inner and outer cylinder side walls are provided with through holes. The electromagnet is located at the gap between the top plate and the second magnet.

[0011] Furthermore, the linkage valve includes a fixing ring and a fixing frame. The fixing ring is fixedly connected to the top of the inner wall of the outer cylinder and to the bottom of the inner wall of the cylinder. A middle cylinder is fixedly connected to the inner wall of the fixing ring. A connecting rod is fixedly connected to the top of the fixing frame, and the bottom of the connecting rod extends through to the top of the middle cylinder and is fixedly connected to the connecting frame.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention utilizes an air pump, blades, and an air duct box to control the rotation of a suspended body via airflow, replacing the traditional method of using magnetic attraction to connect and control the rotation of the suspended body. This avoids the impact of magnetic attraction on the descent of the suspended body and prevents deformation caused by magnetic attraction. In addition, the airflow circulating inside the cylinder also provides a heat dissipation effect for the lamp body, extending its service life. Furthermore, an air outlet is provided, allowing airflow from inside the base to be blown upwards. When the suspended body falls, the upward airflow provides a cushioning effect, preventing wear and tear from collisions with the base. Attached Figure Description

[0019] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Reference Figure 1 and Figure 2 This utility model provides a magnetic levitation rotating lamp, including a base 1, a cylindrical column 2 connected to the top of the base 1, a lamp body 4 fixedly installed on the top of the cylindrical column 2, a levitation body 3 slidably sleeved on the side wall of the cylindrical column 2, a magnet 5 fixedly connected to the bottom of the inner wall of the levitation body 3, an electromagnet 6 installed inside the base 1, a recessed circular groove provided on the top of the levitation body 3, several through slots opened on the side wall of the cylindrical column 2, several blades 9 fixedly connected to the inner wall of the recessed circular groove on the top of the levitation body 3, an air pump 7 installed on the side wall of the base 1, the air pump 7 is used to draw gas from outside the base 1 and inject it into the base 1, and several air outlets 11 are opened on the top of the base 1.

[0021] When in use, after the electromagnet 6 is energized, it generates a repulsive force with the magnet 5, which causes the levitation body 3 to levitate upwards. Gas is injected into the base 1 by the operation of the air pump 7. After the airflow is generated inside the base 1, it flows into the cylinder 2. The airflow flowing through the cylinder 2 can heat up the lamp body 4. As the gas inside the base 1 and the cylinder 2 increases, the gas pressure rises. The gas is ejected through several slots on the side wall of the cylinder 2. The airflow blows onto the blades 9 and generates a pushing force on them, which in turn generates a rotational force on the levitation body 3, causing the levitation body 3 to rotate. When the electromagnet 6 is de-energized, the levitation body 3 falls under the influence of gravity. When the airflow inside the base 1 is ejected through several air outlets 11, the airflow at the top of the base 1 blows upwards, which can buffer the levitation body 3 and prevent the levitation body 3 from colliding with the base 1 and causing wear.

[0022] Reference Figure 3 Each of the several slots on the side wall of the cylinder 2 is fixedly connected to an airway box 10, and each airway box 10 is tilted clockwise at more than 30 degrees.

[0023] By setting an inclined air duct box 10, the airflow blown out by several air duct boxes 10 can have a certain inclination. This setting can make the airflow generate a driving force towards one side of the blade 9.

[0024] Reference Figure 3 Several leaves are tilted clockwise at an angle of more than 30 degrees.

[0025] This configuration allows the blade 9 to form an angle with the inner wall of the recessed circular groove at the top of the suspension body 3. When the airflow blows to one side of the blade 9, the airflow converges at the angle due to its tilt, thereby generating a greater thrust and ensuring that the suspension body 3 rotates.

[0026] Reference Figure 2 The base 1 has a fixed cover 12 fixedly connected to its side wall. The air pump 7 is located inside the fixed cover 12. The top of the fixed cover 12 has several air inlets.

[0027] The fixed cover 12 can protect the air pump 7 and also hide the air pump 7 to improve its appearance.

[0028] Reference Figure 2 The base 1 is equipped with a switching valve assembly 8. When the electromagnet 6 is energized and generates magnetic force, the switching valve assembly 8 will block the air outlet 11. When the electromagnet 6 is de-energized and the electromagnetic force disappears, the switching valve assembly 8 will block the cylinder 2.

[0029] By setting the switching valve assembly 8 to restrict the airflow direction, when the electromagnet 6 is energized and the suspension body 3 is suspended, the airflow blown out through the air outlet 11 has no effect. By closing it with the switching valve assembly 8, the airflow in the groove of the cylinder 2 can be prevented from being diverted. Similarly, when the electromagnet 6 is de-energized and the base 1 falls, the airflow in the groove of the cylinder 2 has no effect. By blocking the cylinder 2 with the switching valve assembly 8, the airflow can only flow through the air outlet 11, thereby ensuring the airflow rate of the air outlet 11 and producing a better buffering effect on the suspension body 3.

[0030] Reference Figure 4 The switching valve assembly 8 includes an inner cylinder 81, which is fixedly connected to the bottom of the inner wall of the base 1. An outer cylinder 82 is slidably sleeved on the side wall of the inner cylinder 81. A top plate 83 is fixedly connected to the top of the side wall of the outer cylinder 82. A magnet 84 is fixedly connected to the bottom of the side wall of the outer cylinder 82. The bottom of the magnet 84 is connected to the bottom of the inner wall of the base 1 via a tension spring 85. The inner wall of the outer cylinder 82 is connected to the cylinder column 2 via a linkage valve 86. The outer cylinder 82 moves down to control the linkage valve 86 to close, and the outer cylinder 82 moves up to control the linkage valve 86 to close. Both the inner cylinder 81 and the outer cylinder 82 have through holes on their side walls. An electromagnet 6 is located at the gap between the top plate 83 and the magnet 84.

[0031] When the electromagnet 6 is energized and has magnetic force, it attracts the second magnet 84 and causes it to move upward. Under the connection effect of the outer cylinder 82, the top plate 83 moves upward and sticks tightly to the top of the inner wall of the base 1, thus blocking the air outlet 11. At this time, the airflow passes through the switching valve assembly 8 and flows only into the cylinder 2. When the electromagnet 6 is de-energized and the magnetic force disappears, the second magnet 84 returns to its position under the pulling effect of the inner cylinder 81. At this time, the linkage valve 86 closes, blocking the airflow flowing through the cylinder 2. In addition, the top plate 83 moves downward and the air outlet 11 is not blocked, so the air outlet 11 has a strong flow effect.

[0032] Reference Figure 4 The linkage valve 86 includes a fixing ring 861 and a fixing bracket 862. The fixing ring 861 is fixedly connected to the top of the inner wall of the outer cylinder 82 and to the bottom of the inner wall of the cylinder column 2. The inner wall of the fixing ring 861 is fixedly connected to the middle cylinder 865. The top of the fixing bracket 862 is fixedly connected to the connecting rod 863. The bottom of the connecting rod 863 passes through to the top of the middle cylinder 865 and is fixedly connected to the connecting bracket 864.

[0033] When the outer cylinder 82 moves down, the connecting frame 864 moves down under the connection of the fixed frame 862 and the connecting rod 863, which closes the middle cylinder 865. At this time, the cylinder column 2 cannot circulate air. When the outer cylinder 82 moves up, the connecting frame 864 moves up, and the inner cavity of the middle cylinder 865 can circulate gas. At this time, the linkage valve 86 is in the open state, and the cylinder column 2 circulates gas normally.
