Description

Technical Field

[0001] The utility model relates to the technical field of incense burning appliances, and in particular to a lifting magnetic suspension structure and an incense tray device. Background Art

[0002] Magnetic suspension ornaments such as magnetic suspension incense trays usually need to place incense or incense powder on the incense tray. The incense or incense powder will produce incense ash after burning, so the incense ash needs to be removed frequently. Existing magnetic suspension incense trays require users to manually put the incense tray into the magnetic suspension track so that the incense tray can be suspended in the air. However, it is easy to offset during the placement process, making the installation and positioning of the incense tray more difficult. At the same time, since the incense tray needs to be taken out frequently to clean the incense ash, the placement process of the magnetic suspension incense tray also becomes more difficult. If the incense tray is installed incorrectly, it is easy to fall from the air, which will not only damage the incense tray, but also cause the incense, incense powder or incense ash on the incense tray to fall to the ground, causing trouble.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships that are based on the positions or location relationships when the product is in normal use.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0029] The utility model provides a lifting magnetic suspension structure, combined with Figures 1 to 9As shown, it includes a magnetic suspension part, a sleeve 2 and a base 3, the magnetic suspension part can be suspended and placed on the sleeve 2, the sleeve 2 and the base 3 are connected to each other by moving up and down, and a magnet assembly that cooperates with the magnetic suspension part is installed in the base 3; when the magnetic suspension part needs to be suspended, the sleeve 2 drives the magnetic suspension part to move downward relative to the base 3 until a suspension force is generated between the magnetic suspension part and the magnet assembly, and then the sleeve 2 is separated from the magnetic suspension part to realize the suspension setting of the magnetic suspension part; when the suspension of the magnetic suspension part needs to be ended, the sleeve 2 moves upward relative to the base 3 to make the sleeve 2 contact with the magnetic suspension part, and the sleeve 2 continues to drive the magnetic suspension part to move upward relative to the base 3 until no suspension force is generated between the magnetic suspension part and the magnet assembly, and then the suspension of the magnetic suspension part is ended.

[0030] The up and down movement of the sleeve 2 relative to the base 3 can be achieved manually or electrically.

[0031] The magnet assembly can form a magnetic field, and the magnetic suspension body is suspended by the suspension force generated between the magnetic field and the magnetic suspension body. The magnetic suspension body is prone to trajectory deviation during the process of entering the magnetic field. Once the deviation is too much, the effect of stable suspension cannot be achieved, so it is difficult to control the angle at which the magnetic suspension body enters the magnetic field. Preferably, entering the magnetic field from directly above the magnetic field can make the suspension of the magnetic suspension body more stable.

[0032] The position of the sleeve 2 in the vertical direction is divided into the highest point and the lowest point. When the sleeve 2 is at the highest point, the upper end surface of the sleeve 2 is located outside the magnetic field or at the edge of the magnetic field. At this time, the user places the magnetic suspension part on the upper end surface of the sleeve 2, and the magnetic suspension part is not affected by the magnetic field, or the magnetic suspension part is affected by the magnetic field very weakly and is not enough to be magnetically suspended.

[0033] When the sleeve 2 starts to descend from the highest point, the magnetic levitation component descends along with the sleeve 2. When the sleeve 2 descends to a certain height so that the magnetic levitation component enters the magnetic field and is magnetically suspended, the magnetic levitation component is separated from the upper end surface of the sleeve 2. The sleeve 2 continues to descend until it reaches the lowest point, and the magnetic levitation component is suspended in the air under the influence of the magnetic field and no longer descends along with the sleeve 2.

[0034] When the user needs to retract the magnetic suspension part, the sleeve 2 starts to rise from the lowest point, and when it rises to a certain height so that the magnetic suspension part abuts against the upper end surface of the sleeve 2, the sleeve 2 drives the magnetic suspension part to rise together until it reaches the highest point, and the magnetic suspension part gradually leaves the magnetic field, thereby stopping suspension. At this time, it is safer for the user to take off the magnetic suspension part, reducing the risk of the magnetic suspension part falling from the air.

[0035] The lifting magnetic levitation structure in the utility model provides protection for the magnetic levitation component through the sleeve 2. The magnetic levitation component relies on the lifting and lowering of the sleeve 2 to start and end suspension, so that the magnetic levitation component is not easy to fall from the air when starting or ending suspension, thereby improving safety.

[0036] Preferably, if Figure 2 As shown, a motor 32 with a screw 31 is fixedly connected inside the base 3, and a limiting cavity 24 threadedly connected to the screw 31 is provided in the sleeve 2. When the motor 32 drives the screw 31 to rotate forward and reverse, the limiting cavity 24 moves up and down along the screw 31, so that the sleeve 2 moves up and down relative to the base 3.

[0037] The forward and reverse helical rotation is divided into forward helical rotation and reverse helical rotation. The forward helical rotation can be clockwise helical rotation or counterclockwise helical rotation, and the reverse helical rotation is opposite to the forward helical rotation. The motor 32 drives the sleeve 2 to move up and down, which is more convenient.

[0038] An internal thread may be directly provided in the limiting cavity 24 , and is threadedly connected to the screw rod 31 via the internal thread, so that when the screw rod 31 rotates forward and reversely, the limiting cavity 24 is driven to move up and down, thereby realizing the lifting and lowering of the sleeve 2 .

[0039] like Figure 1 and Figure 8 As shown, the base 3 is also provided with a button 37 and an electric control board 36, and the motor 32 and the button 37 are electrically connected to the electric control board 36. The button 37 controls the rotation of the motor 32 through the electric control board 36 to make the sleeve 2 move up and down relative to the base 3.

[0040] The button 37 is convenient for the user to control the lifting of the sleeve 2. When the user places the magnetic suspension part on the upper end surface of the sleeve 2, the user presses the button 37 to control the sleeve 2 to descend, so as to drive the magnetic suspension part to start levitation. When the user needs to stop levitation, the button 37 is pressed again to control the sleeve 2 to rise, so as to drive the magnetic suspension part to stop levitation. This arrangement is simple and convenient, and easy to operate. The control principle between the electric control board 36, the button 37 and the motor 32 is the prior art and will not be repeated here.

[0041] Preferably, if Figure 5 As shown, the lower part of the limiting cavity 24 is connected with a fixing member 25 by bolts, and a threaded through hole is provided in the fixing member 25, and the screw rod 31 passes through the through hole and is threadedly connected with the fixing member 25. This arrangement is more convenient to manufacture in terms of process.

[0042] In this embodiment, a screw hole is provided in the side wall of the limiting cavity 24, and a screw hole is also provided on the fixing member 25. The fixing member 25 is fixed to the limiting cavity 24 by bolts, and the fixing member 25 is fixed in position and does not rotate. When the motor 32 drives the screw rod 31 to rotate helically, the fixing member 25 only moves up and down without rotating under the action of the threaded through hole. The up and down displacement of the fixing member 25 drives the peripheral wall of the limiting cavity 24 to move up and down together. The peripheral wall of the limiting cavity 24 is integrally arranged or fixedly connected with the sleeve 2, so that the sleeve 2 also moves up and down together to realize the lifting function.

[0043] like Figure 4 and Fig. 9 As shown, the upper end surface of the sleeve 2 is provided with a positioning groove 21 suitable for placing the magnetic suspension component, a positioning block 22 is provided on the positioning groove 21, and the bottom of the magnetic suspension component is provided with a positioning hole 12 suitable for accommodating the positioning block 22.

[0044] The shape of the positioning groove 21 is adapted to the shape of the magnetic suspension component. In this embodiment, the bottom of the magnetic suspension component is arc-shaped, and the positioning groove 21 is recessed inward from the upper end surface of the sleeve 2, and the positioning groove 21 is also arc-shaped. The positioning block 22 is convexly provided at the center of the positioning groove 21. Preferably, the positioning block 22 is located directly above the magnetic field so that the magnetic suspension component can be located directly above the magnetic field. The positioning hole 12 is recessed at the bottom of the magnetic suspension component, and when the positioning block 22 is placed in the positioning hole 12, the magnetic suspension component is installed.

[0045] Preferably, the positioning groove 21 is located directly above the magnetic field. The positioning groove 21 provides a positioning reference for the installation of the magnetic suspension component. When the magnetic suspension component is installed on the positioning groove 21, it is located directly above the magnetic field, which provides convenience for users to install the magnetic suspension component.

[0046] like Figure 1 and Figure 6 As shown, the magnet assembly includes a permanent magnet 34 and a plurality of electromagnets 35 evenly distributed around the permanent magnet 34, and the magnetic suspension member is provided with a magnet 11 that matches the magnet assembly.

[0047] The magnetic forces between the permanent magnet 34 and the magnet 11 repel each other, so that the magnetic suspension part can be suspended by magnetic force. In this embodiment, there are four electromagnets 35, which are symmetrically arranged around the permanent magnet 34, and the area of ​​the permanent magnet 34 is larger than the area of ​​the electromagnet 35. The magnetic force of the electromagnet 35 can be adjusted by changing the current, so that the electromagnet 35 can correct the deviation of the magnetic suspension part, so that the magnetic suspension part will not deviate out of the magnetic field due to a small force during the suspension process. The small force can be wind force or a slight touch force.

[0048] like Figure 1 and Figure 2 As shown, a limiting step 23 is provided on the edge of the sleeve 2 , and the limiting step 23 is used to limit the downward movement distance of the sleeve 2 .

[0049] In this embodiment, the limiting step 23 is protruded from the peripheral wall of the sleeve 2, and when the lowest surface of the limiting step 23 abuts against the base 3, the outer side wall of the limiting step 23 is nearly parallel to the outer side wall of the base 3 to achieve a smooth transition. This arrangement is more beautiful and further limits the descending distance of the sleeve 2.

[0050] like Figure 1 and Figure 2 As shown, the lower end of the base 3 is provided with a plurality of heat dissipation holes 38. The electric control board 36 is placed at the inner bottom end of the base 3, so that the heat dissipation holes 38 surround the electric control board 36, which is convenient for the electric control board 36 to dissipate heat.

[0051] like Figure 3 , Figure 6 , Figure 7 As shown, preferably, a sliding rod 33 is provided in the base 3 , a limiting member 26 with a limiting hole 27 is provided in the sleeve 2 , and the sliding rod 33 is slidably penetrated in the limiting hole 27 .

[0052] The diameter of the limiting hole 27 is matched with the diameter of the slide bar 33, so that the slide bar 33 is limited in the limiting hole 27, and the slide bar 33 further provides support and limiting functions. In this embodiment, two motors 32 with screws 31 are symmetrically arranged in the base 3, and two slide bars 33 are symmetrically arranged at both ends of one motor 32. The bottom end of the slide bar 33 is connected to the base 3, and the top end of the slide bar 33 is inserted into the limiting hole 27. When the limiting cavity 24 moves up and down along the screw 31, the limiting hole 27 also moves up and down along the slide bar 33. The limiting member 26 is U-shaped, and the upper top end of the U-shape is fixedly connected to the sleeve 2, and the cavity in the middle of the U-shape provides space for the slide bar 33 to move.

[0053] Another embodiment of the utility model provides an incense tray device, including the lifting magnetic suspension structure as described above.

[0054] like Figure 2 As shown, the lifting magnetic levitation structure includes a magnetic levitation part, the sleeve 2 and a base 3, wherein a magnet assembly that cooperates with the magnetic levitation part is installed in the base 3, the magnetic levitation part is an incense tray 1, and a temperature sensor 13 is arranged in the incense tray 1. When the temperature sensor 13 detects that the temperature of the incense tray 1 reaches a preset value, the sleeve 2 moves up relative to the base 3 to make the sleeve 2 contact with the incense tray 1, and the sleeve 2 continues to drive the incense tray 1 to move up relative to the base 3 until no suspension force is generated between the incense tray 1 and the magnet assembly, and the suspension of the incense tray 1 is ended.

[0055] The incense tray 1 suspended in the air can increase the fun and science fiction effect, and promote consumer purchases. The temperature sensor 13 is arranged inside the incense tray 1, and does not affect the use effect of the incense tray 1. The sensing surface of the temperature sensor 13 is close to the upper surface of the incense tray 1 to measure the temperature of the upper surface.

[0056] Preferably, the temperature sensor 13 is connected to the electric control board 36 via a wireless signal. After detecting a preset temperature value, the temperature sensor 13 transmits a wireless signal to the electric control board 36. After receiving the wireless signal, the electric control board 36 controls the motor 32 to rotate, so that the sleeve 2 rises and drives the incense tray 1 to stop floating.

[0057] When the temperature sensor 13 detects that the temperature of the upper surface reaches or exceeds a predetermined temperature value, it means that the incense on the incense tray 1 is completely burned out or about to be completely burned out. At this time, the temperature sensor 13 wirelessly transmits an electrical signal to the electric control board 36, so that the electric control board 36 controls the sleeve 2 to rise, so that the incense tray 1 stops floating. This setting is safer and more reliable, not only can it remind the user that the incense body is completely burned out, but also can prevent the incense tray 1 from being knocked off and the incense ash from spilling on the ground and causing trouble.

[0058] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
