However, the embodiments of this utility model are not limited to those described below. Furthermore, this utility model relates to necessary components in this technical field and should be considered as well-known technology in this technical field, which can be known and mastered by those skilled in the art.

[0025] This utility model discloses a charger with pulse repair function, such as... Figure 3 As shown, it includes a housing and a circuit board 3 disposed inside the housing, such as Figure 1 and Figure 2 As shown, the housing has a front upright plate 1 and a rear upright plate 2. One side of the rear upright plate 2 has a power input terminal 22, and the other side has an output terminal 23 connected to the positive and negative terminals of the battery. Figure 4 As shown, circuit board 3 includes a rectifier and filter module 4, a control circuit module 5, a pulse repair module 8, a feedback module 7, and an output module 6.

[0027] The control circuit module 5 includes a first terminal 37 connected to the voltage control switch 13, a second terminal 38 connected to the power mode control switch 14, a third terminal 31 connected to the pulse constant switching switch 15, and a power comparator 39, all mounted on the circuit board 3. The power comparator 39 is a circuit element capable of comparing the power of two electrical signals. It typically consists of a comparator, a reference power supply, and an input power supply. Its working principle involves amplifying and filtering the two electrical signals before inputting them to the comparator for comparison, thereby determining which signal has a larger or smaller power.

[0028] The pulse repair module 8 includes a fourth terminal 81 connected to the pulse constant switching switch 15, mounted on the circuit board 3, a pulse generator 82, and a pulse amplifier circuit 83. The pulse generator 82 is an instrument used to generate electrical test signals with the required parameters; the pulse amplifier is an electronic device or circuit used to amplify pulse signals. Pulse signals are typically sudden, short-duration current pulses or signals with narrow pulse widths.

[0029] This invention features a pulse repair module 8 and a constant pulse switching switch 15 on the charger. The constant pulse switching switch 15 can switch from constant to pulse mode. The pulse repair module 8 applies a series of high-voltage pulses to the battery, which helps to remove sulfides on the battery plates, effectively restores the battery's performance, extends its lifespan, improves charging efficiency, and makes the battery charge more fully and efficiently.

[0030] This invention enables the charger to charge batteries with different voltages and different conditions by setting a voltage control switch 13 and a power mode control switch 14 on the charger. The power mode control switch 14 allows the power comparator 39 in the charger to compare the charging voltage and charging current of the lead-acid battery in real time, which helps to shorten the charging time and extend the service life of the charger and the battery.

[0031] More specifically, this invention includes a rectifier and filter module 4, which converts the input alternating current (AC) into direct current (DC). A filter circuit removes pulsating components from the DC, resulting in a more stable output voltage. The voltage converted by the rectifier and filter module 4 supplies power to the control circuit module 5 and the pulse repair module 8. The control circuit module 5 can charge batteries with different voltages and conditions, and compare the charging voltage and current of lead-acid batteries in real time. The pulse repair module 8 generates specific pulse signals or waveforms to activate the chemical substances inside the battery, removing harmful substances such as sulfides, thereby restoring the battery's capacity and performance.

[0032] The output terminal 23 of the rectifier and filter module 4 is equipped with a pulse constant switching switch 15. This switch controls the activation of the control circuit module 5 or the pulse repair module 8, switching between constant voltage and current mode and pulse mode. The control circuit module 5 includes a third terminal 31 connected to the pulse constant switching switch 15, and the pulse repair module 8 includes a fourth terminal 81 mounted on the circuit board 3 connected to the pulse constant switching switch 15.

A power mode control switch 14 is provided between the control circuit module 5 and the output module 6. The control circuit module 5 includes a first terminal 37 connected to the voltage control switch 13, a second terminal 38 connected to the power mode control switch 14, and a power comparator 39, all mounted on the circuit board 3. A feedback module 7 is connected in parallel between the control circuit module 5 and the output module 6. The voltage control switch 13 is used to select the range of the charger's output voltage. Simultaneously, the activation of the power mode control switch 14 engages the power comparator 39, adjusting the charging current according to the needs of the lead-acid battery. The charger provides a constant charging current to the lead-acid battery, effectively protecting both the battery and the charger.

[0034] As one of the preferred embodiments of this utility model, such as Figure 1As shown, the voltage control switch 13, the pulse constant switching switch 15, and the power mode control switch 14 are respectively located on the front panel 1. The three buttons on the front panel 1 control the selection of the charger's output voltage range, the switching of the pulse constant mode, and whether the power comparator 39 is engaged. This facilitates user operation.

[0035] As one of the preferred embodiments of this utility model, such as Figure 3 As shown, the rectifier and filter module 4 includes a power input terminal 22, a fuse 33, a bridge rectifier 34, a filter capacitor 35, and a transformer 36, all mounted on the circuit board 3 and connected via connector 32. The power input terminal 22 serves as the power inlet for the entire module, receiving external AC power input. It connects to the circuit board 3 via connector 32 to ensure the stability and safety of the power input. The fuse 33 provides short-circuit protection in the circuit. If an excessive current occurs in the circuit, the fuse 33 will quickly melt and disconnect the circuit, preventing equipment damage or fires.

[0036] Bridge rectifier 34 converts the input AC power into unidirectional pulsating DC power. Filter capacitor 35 filters the pulsating DC power output from bridge rectifier 34, smoothing the voltage waveform, reducing the pulsating component in the current, and making the output voltage closer to ideal DC power. Transformer 36 reduces the input AC voltage to a suitable range for the rectifier circuit to process.

[0037] In one preferred embodiment of this utility model, the output module 6 includes a Zener transistor 61 mounted on the circuit board 3 and an output terminal wire 62 connected to the circuit board 3. The Zener transistor 61 functions to stabilize the output voltage in the output module 6. It can adjust its operating point within a certain range to maintain a stable output voltage. The output terminal wire 62 is used for outputting signals.

[0039] In one preferred embodiment of this utility model, the power comparator 39 and the Zener transistor 61 are each equipped with a heat sink. The heat sink is used to dissipate heat from the power comparator 39 and the Zener transistor 61, preventing overheating and changes in material properties, such as metal wire expansion and insulation layer aging, which could lead to component damage or failure. It also accelerates the aging process of the internal components of the power comparator 39 and the Zener transistor 61, such as electron migration and metallization layer peeling. These aging phenomena shorten the service life of the components and increase equipment maintenance costs and replacement frequency.

[0040] As one of the preferred embodiments of this utility model, such as Figure 2 As shown, an air vent is located in the center of the rear upright plate 2, and a cooling fan 9 is installed on the back of the rear upright plate 2. The cooling fan 9 helps to reduce the temperature inside the charger cavity, preventing the charger from operating at high temperatures. The air vent allows the airflow generated by the cooling fan 9 to pass smoothly through and be discharged to the outside. The size and shape of the air vent need to be carefully calculated and optimized to ensure that the heat dissipation effect is maximized without affecting the appearance and structural strength of the charger.

[0041] In one preferred embodiment of this utility model, the output terminal 23 is equipped with clips 24 that hold the positive and negative terminals of the battery. Clips 24 allow users to directly connect the charger's output terminal 23 to the positive and negative terminals of the battery to be charged. By ensuring tight contact between the clips 24 and the battery terminals, poor contact can reduce charging efficiency or safety hazards. Furthermore, some clips 24 are also designed with an insulating layer or safety latch to prevent accidental electric shock.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
