Description

Technical Field

[0001] The present invention relates to articles, and in particular to a prayer wheel. Background Art

[0002] Most of the existing prayer wheels are either electric or manual separately. The electric prayer wheel is driven by a motor to drive a gear to rotate, and then the gear drives the prayer cylinder to rotate; the manual prayer wheel usually extends several handles from the lower part of the prayer cylinder and is pushed by hand. However, neither the electric prayer wheel nor the manual prayer wheel can effectively prevent the prayer wheel from reversing and cannot keep the rotation speed of the prayer wheel constant. If the rotation speed is too fast, it will cause damage to the machine. In this case, it becomes extremely urgent to solve these problems, but it is a great difficulty for designers to design a prayer wheel with anti-reverse and constant rotation speed. Summary of the Invention

[0003] The purpose of the present invention is to provide a prayer wheel to meet the continuous growth of the future market demand for prayer wheels with anti-reverse and constant rotation speed.

[0004] To achieve the above purpose, the technical solution of the present invention provides a prayer wheel, including a base and a prayer cylinder. The base and the prayer cylinder are connected by a rotating device. At least two magnets are provided in the prayer cylinder. A circuit control board, a coil and a sensor are provided in the base. The base is provided with a power interface, and the power interface is connected to the circuit control board by a wire. The circuit control board is connected to the sensor by a wire. The circuit control board is connected to the coil by a wire. The sensor can sense the rotation direction and speed of the prayer cylinder.

[0005] Further, the rotating device includes a central shaft and a bearing. The bearing is installed at the bottom inside the prayer cylinder. One end of the central shaft is fixedly installed inside the base, and the other end of the central shaft is matched with the prayer cylinder. The central shaft is matched with the bearing.

[0006] In this technical solution, at least two blades are installed outside the prayer cylinder. The blades are in a hemispherical structure with a hollow in the middle.

[0007] Further, four blades are installed outside the prayer cylinder. The blades are installed outside the prayer cylinder, and the hollowed surface of the blades faces counterclockwise.

[0008] As a preferred embodiment, four magnets are provided at the bottom inside the prayer cylinder.

[0009] In this technical solution, an iron core is placed inside the coil.

[0010] In any of the above technical solutions, a head is installed on the prayer cylinder, and the power interface is arranged outside the base.

[0011] In summary, the technical solution of the present invention has the following beneficial effects: the structural design of the present invention is reasonable, and the circuit control board adjusts the energized state of the coil to prevent the prayer wheel from rotating counterclockwise by sensing the rotation direction of the prayer wheel through the sensor, which solves the problem of counterclockwise rotation often occurring in traditional prayer wheels; the circuit control board adjusts the energized state of the coil to prevent the prayer wheel from rotating too fast by sensing the rotation speed of the prayer wheel through the sensor, so that the prayer wheel is always kept at a reasonable rotation speed, which solves the problem of too fast rotation speed caused by the traditional prayer wheel using a gear set for speed regulation; by installing blades on the outside of the prayer wheel, the blades can drive the prayer wheel to rotate by external driving forces such as wind or manual turning, which solves the problem of wind propulsion, manual turning and magnetic propulsion being able to be achieved on the same prayer wheel at the same time; by using the bearing to cooperate with the central shaft and using the magnetic force generated after the coil is energized as the power, the noise problem caused by the traditional prayer wheel using a motor to provide power is solved.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention, but this does not constitute a limitation on the protection scope of the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This embodiment provides a prayer wheel, including a base 1 and a prayer drum 2. The base 1 and the prayer drum 2 are connected through a rotating device. The base 1 remains relatively fixed and one end of the rotating device is installed and fixed. The prayer drum 2 cooperates with the other end of the rotating device. When the prayer drum 2 is acted upon by an external driving force, it rotates around the rotating device. Four magnets 9 are arranged at the bottom of the prayer drum 2. A coil 7 is arranged in the base 1. An iron core is placed in the coil 7. The purpose of placing the iron core in the coil 7 is to increase the magnetic field strength generated by the coil 7. A circuit control board 6 and an inductor 8 are arranged in the base 1. A power interface 5 is arranged outside the base 1. Of course, the power interface 5 can also be arranged in the base 1, which can also achieve the same function. The power interface 5 is connected to the circuit control board 6 through a wire, the circuit control board 6 is connected to the sensor 8 through a wire, and the circuit control board 6 is connected to the coil 7 through a wire. When the power interface 5 is supplied with current, the current is supplied to the circuit control board 6 through the wire, and the circuit control board 6 supplies the current to the coil 7. The coil 7 will generate a certain magnetic field strength, and the magnetic field generated by the coil 7 interacts with the magnetic field generated by the magnet 9, and the magnetic force generated thereby pushes the prayer wheel 2 to rotate in the clockwise direction. Since there are four evenly distributed magnets 9, the prayer wheel 2 can be continuously and stably driven to rotate. Of course, the above-mentioned magnets 9 can also be set to three, which can also achieve the same function.

[0020] Specifically, after the circuit control board 6 passes current into the sensor 8, the sensor 8 can sense the rotation direction and speed of the prayer wheel 2. When it senses that the prayer wheel 2 rotates counterclockwise, the signal is transmitted to the circuit control board 6, and then the circuit control board 6 disconnects the current of the coil 7, causing the prayer wheel 2 to stop running. When the sensor 8 senses that the rotation speed of the prayer drum 2 is too fast, the signal is transmitted to the circuit control board 6, and then the circuit control board 6 temporarily disconnects the current of the coil 7, so that the rotation speed of the prayer drum 2 decreases, and the rotation speed of the prayer drum 2 is always constant at a suitable speed; the prayer drum 2 is externally installed with four blades 4, the blades 4 are hemispherical and hollowed out in the middle, and the hollowed out surface of the blades 4 faces the counterclockwise direction. When the wind blows, the hollowed out surface of the blades 4 is pushed by the wind, and then the blades 4 drive the prayer drum 2 to rotate clockwise. The hollowed out surface of the blades 4 facing the counterclockwise direction can prevent the prayer drum 2 from reversing. Through the action of the blades 4, the prayer wheel can rotate even when there is no power. The above-mentioned installed blades 4 can also be three, which can also achieve the same function. In addition, the blades 4 can also drive the prayer drum 2 to rotate by manual toggling. A head 3 is installed on the prayer drum 2. The function of installing the head 3 is to make the prayer wheel more beautiful.

[0021] Specifically, the above-mentioned rotating device includes a central shaft 11 and a bearing 10. The bearing 10 is installed in a placed manner at the bottom of the prayer cylinder 2. One end of the central shaft 11 is fixed in the base 1 by means of bolts or snaps, and remains relatively fixed with the base 1. The other end of the central shaft cooperates with the upper end of the inside of the prayer cylinder 2. At the same time, the central shaft 11 cooperates with the bearing 10. Through such an installation, the prayer cylinder 2 can rotate around the central shaft 11 when subjected to an external driving force.

[0022] The structural design of the present invention is reasonable. By sensing the rotation direction of the prayer drum 2 by the sensor 8, the circuit control board 6 adjusts the power-on state of the coil 7 to prevent the prayer drum 2 from rotating counterclockwise, which solves the problem of counterclockwise rotation often occurring in traditional prayer wheels; by sensing the rotation speed of the prayer drum 2 by the sensor 8, the circuit control board 6 adjusts the power-on state of the coil 7 to prevent the prayer drum 2 from rotating too fast, so that the prayer drum 2 is always kept at a reasonable rotation speed, which solves the problem of too fast rotation speed caused by the traditional prayer wheel using a gear set for speed regulation; by installing blades 4 on the outside of the prayer drum 2, the blades 4 can drive the prayer drum 2 to rotate when subjected to external driving forces such as wind or manual turning, which solves the problem of wind driving, manual turning and magnetic driving being able to be simultaneously realized on the same prayer wheel; by using the bearing 10 to cooperate with the central shaft 11 and using the magnetic force generated by the coil 7 after being energized as the power, the noise problem caused by the traditional prayer wheel using a motor to provide power is solved.

[0023] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
