Description

Technical Field

[0001] This utility model relates to the field of lighting, specifically an LED lighting circuit for a vacuum cleaner brush head. Background Technology

[0002] The primary purpose of a vacuum cleaner's floor brush light is to enhance cleaning precision and convenience, especially in low-light environments. It assists in cleaning in dark areas, illuminating areas like under sofas, beds, and cabinet crevices, helping users see hidden dust, hair, or debris and avoid missing any spots. It provides real-time feedback on cleaning results, with the light directly illuminating the floor, allowing users to visually observe the before-and-after comparison and confirm whether stubborn stains have been removed (especially effective on dark carpets or floors). It is highly adaptable to low-light environments, operating without additional lighting at night or when curtains are closed, reducing usage limitations.

[0003] Currently, some vacuum cleaners with long suction pipes cannot meet the requirements of ground brush lighting controlled by the control board, which is inconvenient to use and needs to be improved. Utility Model Content

[0016] Figure 1This is a circuit diagram of an LED lighting circuit for a vacuum cleaner brush head. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 A vacuum cleaner brush head LED lighting circuit, comprising:

[0019] The ball switch module is used to output a start signal when the user pushes the floor brush back and forth by working with the ball switch and the XOR gate.

[0020] The boost module is used to operate based on the start signal, complete the boost output, and power the lighting module;

[0021] Lighting module for work lighting;

[0022] The output of the ball switch module is connected to the input of the boost module, and the output of the boost module is connected to the input of the lighting module.

[0023] In this embodiment: Please refer to Figure 1 The ball switch module includes a ball switch PL1, an XOR gate IC3, and an XOR gate IC2. One end of the ball switch PL1 is connected to the power supply voltage VCC. The other end of the ball switch IC1 is connected to one end of resistor R12, one end of resistor R9, and the B terminal of XOR gate IC3. The other end of resistor R12 is grounded. The other end of resistor R9 is connected to one end of capacitor C4, one end of resistor R11, and the A terminal of XOR gate IC3. The other end of capacitor C4 and resistor R11 are grounded. XOR gate IC2... The Y terminal of C3 is connected to the base of transistor Q2 through resistor R10. The emitter of transistor Q2 is grounded. The collector of transistor Q2 is connected to one end of resistor R1. The other end of resistor R1 is connected to one end of resistor R7, one end of capacitor C3, and the A terminal of XOR gate IC2. The other end of capacitor C3 is grounded. The other end of resistor R7 is connected to the supply voltage VCC. One end of resistor R8 is connected to the B terminal of XOR gate IC2. The Y terminal of XOR gate IC2 is connected to the input terminal of the boost module.

[0024] The power supply voltage VCC is obtained by connecting two dry batteries in series. When the user pushes the floor brush back and forth, the ball switch PL1 is in a back-and-forth closed and open state. The signal at the B terminal of XOR gate IC3 is synchronized with the state of ball switch PL1, being high when closed and low when open. The delay circuit composed of capacitor C4 and resistor R9 causes the signals at the A and B terminals of XOR gate IC3 to be out of sync when the state of ball switch PL1 changes. This causes XOR gate IC3 to output a pulse signal that changes synchronously with the state of ball switch PL1. This pulse signal synchronously controls the conduction and cutoff of transistor Q2, with a high level for conduction and a low level for disconnection.

[0025] When transistor Q2 is turned on, the voltage across capacitor C3 is discharged through resistor R1 and transistor Q2, causing the voltage across capacitor C3, i.e., the voltage at terminal A of XOR gate IC2, to be lower than the voltage at terminal B of XOR gate IC2. At this time, the voltage at terminal B of XOR gate IC2 is the high level of the supply voltage VCC, and terminal A is the low level. According to the XOR gate logic IC2, the output level is high, driving the boost module to work.

[0026] In this embodiment: Please refer to Figure 1 When capacitor C3 is discharged, it starts to charge through resistor R7, and it takes 10 seconds to reach the voltage of the supply voltage VCC.

[0027] When the ball switch PL1 is stationary, transistor Q2 is continuously off, and capacitor C3 starts charging from the discharged state through resistor R7. Based on the RC charging time of the capacitor, it takes about 10 seconds to reach the supply voltage VCC. During these 10 seconds, XOR gate IC2 maintains a high output level, the boost module works, and the lighting module works. After about 10 seconds, both terminals A and B of XOR gate IC2 are high, XOR gate IC2 outputs a low level, the boost module stops working, and the lighting module stops working. In other words, when the ball switch PL1 switches its state once, the LED of the lighting module is lit for about 10 seconds. The LED will not flicker when the user pushes the ground brush back and forth.

[0028] In this embodiment: Please refer to Figure 1 The boost module includes chip IC1, model number LY1032. Pin 1 of chip IC1 is connected to one end of resistor R2 and one end of resistor R6. The other end of resistor R2 is connected to the output terminal of the ball switch module, and the other end of resistor R6 is grounded. Pin 3 of chip IC1 is connected to the power supply voltage VCC, one end of capacitor C1, and one end of inductor L1. The other end of capacitor C1 is grounded, and the other end of inductor L1 is connected to pin 5 of chip IC1. Pin 4 of chip IC1 is connected to one end of capacitor E1, one end of capacitor C2, and the lighting module. The other end of capacitor E1 and the other end of capacitor C2 are grounded.

[0029] Chip IC1 is a boost converter chip. The CE pin (pin 1) is the enable signal, which is active high and controlled by the output pin (Y terminal) of XOR gate IC2. Therefore, when XOR gate IC2 outputs a high level, chip IC1 works to boost and drive the lighting module.

[0030] In this embodiment: Please refer to Figure 1 The lighting module includes multiple lighting units, each of which includes a light-emitting diode (LED1) and a resistor (R3). The positive terminal of the LED1 is connected to the output terminal of the boost module, and the negative terminal of the LED1 is connected to one end of the resistor (R3). The other end of the resistor (R3) is grounded.

[0031] After voltage input, LED1 emits light, and the lighting module can be configured with different numbers of lighting units according to actual conditions, such as... Figure 1 As shown, there are 3 lighting units.

[0032] The working principle of this utility model is as follows: the ball switch module is used to output a start signal when the user pushes the floor brush back and forth through the ball switch and the XOR gate; the boost module is used to work based on the start signal, complete the boost output, and power the lighting module; the lighting module is used for working lighting.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
