Description

Technical Field

[0001] The utility model particularly relates to a fast-discharging electric mosquito swatter control circuit. Background Art

[0002] Electronic mosquito swatters (also known as "swatters") are popular small household appliances in the summer due to their practicality, effective mosquito (and fly and moth) control, chemical-free operation, and safety and hygiene. These swatters typically use two 1.5V alkaline or rechargeable batteries. A boost circuit generates a voltage of 2500V to 3000V across the power grid (current is less than 10 mA, harmless to humans and animals). When mosquitoes or flies contact the high-voltage grid, they cause a short circuit, resulting in the insects being killed by the current or arc, either burning, stunning, or electrocuting.

[0003] To enhance mosquito repellent effectiveness, many mosquito swatters typically have a large storage capacitor on the back. This capacitor's charge is used to kill mosquitoes, and the circuit then quickly recharges the capacitor. However, after use, the capacitor often retains thousands of volts of electricity. If someone accidentally touches the inner or outer mesh, they could experience a stinging sensation, posing a safety hazard. Summary of the Invention

[0014] The symbols shown in the drawings are as follows: power grid 10 , sensor 20 . DETAILED DESCRIPTION

[0015] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0016] Reference below Figure 1 A fast-discharging electric mosquito swatter control circuit according to an embodiment of the present invention is described, including a power grid 10 and a transformer T1. The output end of the transformer T1 is connected to the power grid 10. A discharge circuit is provided between the power grid 10 and the transformer T1. Pin 1 of the transformer T1 is connected to a touch pressure switch KEY, which is connected to a charging circuit. The discharge circuit includes a first resistor R1 and a polypropylene capacitor CBB. The first resistor R1 and the polypropylene capacitor CBB are connected in parallel to the power grid 10.

[0017] The discharge circuit of this circuit also includes a second diode D2 and a first capacitor C1. The second diode D2 and the first capacitor C1 are connected in series. The negative end of the second diode D2 is connected to pin 5 of the transformer T1. One end of the first capacitor C1 is connected to pin 6 of the transformer T1. The common end between the second diode D2 and the first capacitor C1 is connected to the first diode D1. The common end between pin 6 of the transformer T1 and the first capacitor C1 is connected to a third diode D3. The common end between the negative end of the second diode D2 and pin 5 of the transformer T1 is connected to a mica capacitor CY1. The mica capacitor CY1 is connected to the cathode of the third diode D3, and the common end between the mica capacitor CY1 and the cathode of the third diode D3 is connected to the first resistor R1.

[0018] This circuit instantly cuts off power by releasing the touch-pressure switch KEY, and cooperates with the discharge circuit to consume the remaining power in the power grid, which can quickly consume electricity and improve safety. The first resistor R1 consumes the remaining power in the power grid and also consumes the remaining power in the mica capacitor CY1.

[0019] When this circuit is used daily, press the touch switch KEY to turn it on, and the charging circuit supplies power to the transformer T1, which can kill mosquitoes.

[0020] In this circuit, the common terminal between the touch switch KEY and pin 1 of transformer T1 is connected to a second light-emitting diode (LED2) and a first transistor (Q1), respectively. Pin 2 of transformer T1 is connected to a third resistor (R3), which is also connected to the base of the first transistor (Q1). The emitter of the first transistor (Q1) is connected to pin 3 of transformer T1. The second light-emitting diode (LED2) is connected to a second resistor (R2), one end of which is connected to pin 3 of transformer T1. When the touch switch KEY is pressed, the second light-emitting diode (LED2) illuminates, indicating that the entire circuit is powered. The control voltage applied through the second resistor (R2) protects the second light-emitting diode (LED2).

[0021] The charging circuit of this circuit includes a fourth diode D4, a rechargeable battery BAT, a second transistor Q2, a fifth resistor R5 and a fourth resistor R4. The common end between the fourth diode D4 and the rechargeable battery BAT is connected to the emitter of the second transistor Q2. The fifth resistor R5 and the fourth resistor R4 are connected in series. The common end between the fifth resistor R5 and the fourth resistor R4 is connected to the base of the second transistor Q2. The fifth resistor R5 is connected to the positive electrode of the fourth diode D4, and the fourth resistor R4 is connected to the negative electrode of the rechargeable battery BAT. The fourth diode D4 in the charging circuit implements unidirectional power supply to the rechargeable battery BAT. And

[0022] The charging circuit in this circuit also includes a sixth resistor R6 and a first light-emitting diode LED1. The sixth resistor R6 and the first light-emitting diode LED1 are connected in series and connected to the common terminal of the fourth diode D4 and the fifth resistor R5. The first light-emitting diode LED1 is connected to the common terminal between the four resistors R4 and the negative terminal of the rechargeable battery BAT. The first light-emitting diode LED1 in the charging circuit illuminates during the charging process, indicating the charging status of the charging circuit for easy user observation. Furthermore, the circuit utilizes a second light-emitting diode LED2, a second resistor R2, and a third resistor R3 to dissipate residual power between the transformer T1 and the touch-sensitive switch KEY, achieving dual power consumption.

[0023] The collector of the second transistor Q2 in this circuit is connected to the touch-pressure switch KEY via the position switch KEY1. When the position switch KEY1 is turned on and momentarily energized in conjunction with the touch-pressure switch KEY, the discharge circuit and transformer T1 receive power. The position switch KEY1 has two positions: a first position and a second position. The first position controls the output voltage of transformer T1 to 3500V, while the second position controls the output voltage of transformer T1 to 2800V. This allows for electric shocks to be delivered to insects other than mosquitoes.

[0024] The charging circuit of this circuit is equipped with a sensor 20 at its input. Sensor 20 is connected to the anode of a fourth diode D4. When a person approaches the detection range of sensor 20, the sensor's resistance increases, causing a power outage. Transformer T1 loses power and stops operating, simultaneously de-energizing grid 10. This prevents injuries from high voltage exposure to the grid 10, providing safety protection.

[0025] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
