[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Reference Figures 1 to 7 As shown, the present invention provides a rectification and polarity control device for an impulse current generator, comprising: a substrate 1, a driving mechanism 2, a contact 3 and a controller.

[0023] In this embodiment, the substrate is arranged vertically. The bottom of the substrate is mounted on the ground through a base. The substrate 1 is rectangular. The substrate 1 has a front side and a back side.

[0024] A revolving plate 11 is rotatably mounted on the front side of the base plate 1. A bridge rectifier circuit 4 is mounted on the revolving plate 11.

[0025] The driving mechanism 2 is mounted on the base plate 1. The driving mechanism 2 is used to drive the rotary plate 11. In this embodiment, the driving mechanism 2 is mounted on the back side of the base plate.

[0026] See also Figure 1 and Figure 2 As shown, the rotation center of the rotating plate 11 is coaxially connected with a rotating shaft 12. The rotating shaft 12 is rotatably connected to the base plate 1. In this embodiment, the base plate is provided with an axial hole. The rotating shaft is rotatably inserted into the axial hole of the base plate.

[0027] As a preferred embodiment, the driving mechanism 2 is a motor, and the output end of the motor is connected to the rotating shaft 12 in a transmission manner.

[0028] As a preferred embodiment, the output end of the motor is connected to the rotating shaft 12 via a belt 21 or a chain transmission.

[0029] In this embodiment, the output end of the motor is connected to one end of the rotating shaft 12 through a belt drive. The rotating plate is connected to the other end of the rotating shaft.

[0030] Four contacts 3 are mounted on the front of the substrate 1, one pair of contacts is connected to an AC power source via a terminal, and the other pair of contacts is connected to a DC output via a terminal.

[0031] In this embodiment, the bridge rectifier circuit 4 includes four connection terminals 41 and four silicon rectifier diodes 42. The specific structure of the bridge rectifier circuit, such as how to connect the silicon rectifier diodes, is a prior art and will not be described in detail here. The four connection terminals 41 of the bridge rectifier circuit 4 are pressed against the four contacts 3 one by one. When the rotating plate is in this position, the output voltage of the bridge rectifier circuit is in positive polarity.

[0032] The four connection terminals 41 are arranged at intervals along the circumferential direction of the rotation center of the rotating plate 11. The four connection terminals are arranged in a square or diamond shape. When the rotating plate rotates 180°, the four connection terminals are accurately pressed against the four contacts again, but when the rotating plate is in this position, the polarity of the output voltage of the bridge rectifier circuit is changed and is in a negative polarity.

[0033] The controller (not shown in the drawings) is connected to the driving mechanism 2. The controller drives the rotary plate 11 to rotate 180 degrees through the driving mechanism 2 to switch the polarity of the output voltage of the bridge rectifier circuit 4. As a preferred embodiment, the rectification and polarity control device of the impulse current generator of the present invention further includes an inductive sensor 5. The inductive sensor 5 is used to sense whether the connection terminal 41 is in accurate contact with the contact 3, that is, whether the output voltage of the bridge rectifier circuit is in positive polarity or negative polarity. The inductive sensor 5 is mounted on the substrate 1. The controller signal is connected to the inductive sensor 5. The inductive sensor is connected to the controller through a wire signal.

[0034] In this embodiment, the induction sensor 5 is an infrared sensor. Preferably, there are two induction sensors 5.

[0035] Specifically, one of the inductive sensors 5 is used to sense whether the connecting terminal 41 is in accurate contact with the contact 3 when the bridge rectifier circuit 4 is in the positive polarity position; the other inductive sensor 5 is used to sense whether the connecting terminal 41 is in accurate contact with the contact 3 when the bridge rectifier circuit 4 is in the negative polarity position.

[0036] In this embodiment, the controller is connected to an alarm. When the inductive sensor 5 fails to sense whether the connecting terminal 41 is in accurate contact with the contact 3, the controller turns on the alarm to send out an alarm signal.

[0037] The present invention provides a rectification and polarity control method of an impulse current generator using a rectification and polarity control device of an impulse current generator, comprising the following steps: S1. Connect two contacts 3 to an AC power source and connect the other two contacts 3 to a DC output, so that the bridge rectifier circuit 4 on the rotary plate 11 outputs a positive polarity voltage.

[0038] S2. When the polarity of the output voltage of the bridge rectifier circuit 4 needs to be converted, the controller drives the rotating plate 11 to rotate 180° through the driving mechanism 2 to convert the polarity of the output voltage of the bridge rectifier circuit 4, so that the bridge rectifier circuit 4 outputs a negative polarity voltage.

[0039] The back of the substrate of the rectification and polarity control device of the impulse current generator of the present invention is provided with four binding posts, which are respectively connected to four metal contacts, wherein two binding posts are connected to the AC power input, and the other two binding posts are connected to the DC output.

[0040] A controller and a driving mechanism are arranged on the substrate. The controller controls the driving mechanism and drives the rotating plate to rotate through the rotating shaft to convert the polarity of the output voltage of the bridge rectifier circuit.

[0041] Two infrared sensors are arranged on the front of the base plate, which work together with the openings on the rotating plate and the infrared reflection points to position the rotating plate. The infrared sensor is connected to the controller. The controller is connected to the alarm. The alarm is an LED light.

[0042] When the controller obtains a "positive polarity" or "negative polarity" signal input from the outside, the detection module in the controller obtains signals from two infrared sensors to determine whether the polarity of the bridge rectifier circuit needs to be adjusted.

[0043] When the detection module determines that the polarity needs to be adjusted, the controller controls the driving mechanism (i.e., the motor) to rotate, driving the rotating plate to rotate. After the rotating plate rotates, when the infrared sensor gives an indication that the adjustment is in place, the controller stops the rotation of the motor, so that the rotating plate is adjusted in place, and the alarm (LED light) gives a prompt that the adjustment is in place (such as turning the LED light on or off). Charging cannot be performed before the infrared sensor gives a signal.

[0044] The rectifier diodes in the bridge rectifier circuit have the characteristics of half-wave rectification. By combining them, the input AC power can be rectified into unipolar DC power (see Figure 6 and Figure 7 Schematic diagram).

[0045] The rectification and polarity control device of the impulse current generator of the present invention utilizes the controller therein to control the driving motor to drive the rotation of the rotating plate to change the polarity of the bridge rectifier circuit. The same bridge rectifier circuit can be used, and there is no need to make additional connections to the equipment. The polarity of the impulse current can be conveniently and reliably adjusted, thereby reducing the production cost of the impulse current generator.

[0046] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
