When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] Since it usually takes a certain amount of time to clean the ear canal with an electric ear cleaner, if the user is unable to notice the power status before using the electric ear cleaner, it may cause unstable power or sudden power outage during the cleaning process, causing trouble and inconvenience to the user.

[0039] In order to solve the above problems, the utility model provides an electric ear cleaner.

[0040] In one embodiment of the present invention, Figure 1 As shown, the electric ear cleaner comprises:

[0041] Battery 03;

[0042] Ear cleaning component 06;

[0043] The driving circuit 05 is connected to the battery 03; the driving circuit 05 is used to drive the ear cleaning component 06 to work;

[0044] The power detection circuit 02 is connected to the battery 03; the power detection circuit 02 is used to detect the power of the battery 03 and output a power detection signal;

[0045] The power display circuit 04 is used to display the power of the battery 03;

[0046] The control circuit 01 is connected to the battery 03, the drive circuit 05, the power detection circuit 02 and the power display circuit 04 respectively; the control circuit 01 is used to control the operation of the drive circuit 05; the control circuit 01 is also used to receive a power detection signal, and control the operation of the power display circuit 04 according to the power detection signal.

[0047] In the present embodiment, the ear-washing assembly 06 can include a liquid storage bottle and a liquid spray head, and the liquid storage bottle is communicated with the liquid spray head through a water outlet pipe. Wherein, the driving circuit 05 can drive the washing liquid in the liquid storage bottle to spray out through the liquid spray head. In the present embodiment, the electric quantity of the battery 03 can be detected by the electric quantity detection circuit 02 and an electric quantity detection signal can be output, the control circuit 01 receives the electric quantity detection signal, and the specific electric quantity of the battery 03 is analyzed according to the electric quantity detection signal, and the electric quantity display circuit 04 is controlled to display the specific electric quantity. The electric quantity display circuit 04 can be a display screen, a digital tube or other forms of display devices. In this way, the present embodiment can allow the user to know the remaining electric quantity of the battery 03 in time through the electric quantity display circuit 04, so as to facilitate the user to better arrange the use of the electric ear-washing device, such as being able to have sufficient electric quantity in advance before use, then there will be no situation of unstable electric power or sudden power failure during the cleaning process.

[0048] In this embodiment, the ear washing component 06 may also include a waste liquid recovery mechanism. When the ear washing liquid flows out after flushing and cleaning the user's ear canal, it can flow out to the waste liquid recovery mechanism to prevent the ear washing waste liquid from flowing out to other places to bring discomfort to the user or cause secondary pollution.

[0049] In this embodiment, the ear cleaning component 06 may further include a heater. The liquid storage bottle may be designed as a detachable structure. In this way, in this embodiment, the ear cleaning liquid in the disassembled liquid storage bottle may be heated to a suitable temperature by the heater, and then assembled into the electric ear cleaning device for ear cleaning operation, which may bring a more comfortable experience to the user.

[0050] In the present embodiment, the electric ear cleaner can include four working modes, namely gentle mode, cleaning mode, spot-shooting mode and custom mode. In gentle mode, the driving circuit 05 works with a lower driving power, which can provide a gentler ear-washing experience. In clean mode, the driving circuit 05 works with a higher driving power, which can provide a cleaner ear-washing experience. In spot-shooting mode, the driving circuit 05 works with alternating high and low driving powers, that is, cleaning the ear canal in an intermittent jetting mode, which is gentler and softer during the ear-washing process than the continuous jetting mode, and can reduce the stimulation to the ear canal tissue. In custom mode, the user can set the working mode of the electric ear cleaner to a preferred mode, such as working in gentle mode, cleaning mode or spot-shooting mode.

[0051] In this embodiment, Figure 6As shown, the control circuit 01 may include a control chip U1. The power detection circuit 02 may include a twenty-second resistor R22 and a twenty-third resistor R23. Among them, one end of the twenty-second resistor R22 is connected to the battery 03; the other end of the twenty-second resistor R22 and one end of the twenty-third resistor R23 are connected to the control circuit 01; the other end of the twenty-third resistor R23 is grounded. Then the control circuit 01 can obtain the power information of the battery 03 according to the voltage output from the BAT_DET terminal, that is, the power detection signal, and control the power display circuit 04 to display the power according to the power signal.

[0052] In the present invention, the driving circuit 05 can drive the ear cleaning component 06 to complete the work of cleaning the ear canal. During use, the present invention can detect the power of the battery 03 through the power detection circuit 02 and output a power detection signal, and the control circuit 01 receives the power detection signal, and analyzes the specific power of the battery 03 according to the power detection signal to control the power display circuit 04 to display the specific power. In this way, the present invention can allow the user to know the remaining power of the battery 03 in a timely manner through the power display circuit 04, so as to facilitate the user to better arrange the use of the electric ear cleaner. For example, if the power can be fully charged before use, there will be no unstable power or sudden power outage during the cleaning process.

[0053] Further, in an embodiment of the present invention, if Figure 2 As shown, the electric ear cleaner also includes a charging circuit 07; the charging circuit 07 is connected to the external power supply voltage, the control circuit 01 and the battery 03 respectively; the charging circuit 07 is used to manage the charging of the battery 03; the control circuit 01 is also used to control the operation of the charging circuit 07.

[0054] In this embodiment, the battery 03 is a rechargeable battery 03, and the charging circuit 07 can manage the charging of the battery 03. For example, the charging circuit 07 can convert the external power supply voltage into a charging voltage suitable for charging the battery 03, and can also manage the processes of starting charging, stopping charging, and charging rate of the battery 03. The control circuit 01 can control the charging circuit 07 to start charging and stop charging to ensure that the battery 03 can be charged correctly and remain safe during the charging process.

[0055] Further, in an embodiment of the present invention, if Figure 2 As shown, the electric ear cleaner also includes a battery protection circuit 08, which is respectively connected to the control circuit 01, the drive circuit 05, the power detection circuit 02, the power display circuit 04, the charging circuit 07 and the battery 03; the battery protection circuit 08 is used to limit the charging current and the discharging current of the battery 03.

[0056] In this embodiment, the battery protection circuit 08 may include a battery protection chip U3. In this embodiment, the battery 03 may be protected from overcurrent. When an abnormally high current appears during the charging and discharging process of the battery 03, the current may be limited or the power may be cut off to prevent the battery 03 from being overloaded, heated or damaged. In this embodiment, the battery 03 may also be protected from overcharge. For example, when the battery 03 reaches a full charge state, the battery protection chip U3 may control the charging to stop, so as to avoid safety risks such as overheating, leakage or explosion of the battery 03 caused by overcharging. In this embodiment, the battery 03 may also be protected from overdischarge. When the battery 03 power level drops to a too low level, the battery protection chip U3 may cut off the power supply of the battery 03 to prevent the battery 03 from continuing to discharge, so as to avoid damage or failure to charge normally caused by excessive discharge of the battery 03. In this way, in this embodiment, the charging and discharging safety of the battery 03 may be protected.

[0057] Further, in an embodiment of the present invention, if Figure 2 As shown, the electric ear cleaner also includes a key circuit 09, which is connected to the control circuit 01 and the battery 03 respectively; the key circuit 09 is used to input a control signal; the control circuit 01 is also used to receive the control signal and work according to the control signal.

[0058] In this embodiment, Figure 6 As shown, the key circuit 09 includes a first electronic switch S1 and a second electronic switch S2. A control signal can be input through the first electronic switch S1 and the second electronic switch S2, and the control circuit 01 receives the control signal to work. For example, a control signal for controlling the electric ear cleaner to turn on and off can be input through the first electronic switch S1, or a control signal for controlling the electric ear cleaner to switch working modes can be input through the second electronic switch S2. In this way, in this embodiment, the user can control the operation of the electric ear cleaner through the key circuit 09.

[0059] Further, in an embodiment of the present invention, if Figure 2 As shown, the electric ear cleaner further includes an indicator light circuit 10 , which is connected to the control circuit 01 and the battery 03 respectively; the control circuit 01 is also used to control the operation of the indicator light circuit 10 .

[0060] In the present embodiment, when the electric ear cleaner is in different states, such as in the power-on state, the control circuit 01 controls the indicator light to light up, and when in the power-off state, the control indicator light goes out. The indicator light circuit 10 may include a plurality of indicator lights, and when the electric ear cleaner is in different operating modes, the corresponding indicator lights are on, and the remaining indicator lights are off. In this way, in the present embodiment, the user can identify the current state of the electric ear cleaner through the indicator light circuit 10.

[0061] Further, in an embodiment of the present invention, if Figure 3 and Figure 6 As shown, the driving circuit 05 includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a first capacitor C1, a second capacitor C2, a first diode D1, a first NMOS transistor Q1, a second NMOS transistor Q2 and a driving motor M;

[0062] Among them, one end of the first resistor R1 is connected to the control circuit 01; the other end of the first resistor R1, the gate of the first NMOS tube Q1 and the gate of the second NMOS tube Q2 are connected; the source of the first NMOS tube Q1, the source of the second NMOS tube Q2, and one end of the third resistor R3 are connected to one end of the fourth resistor R4; the drain of the first NMOS tube Q1, the drain of the second NMOS tube Q2, one end of the first capacitor C1, and the positive electrode of the first diode D1 are connected to one end of the drive motor M; the other end of the first capacitor C1, the other end of the first diode D1, and the other end of the drive motor M are connected to the power input end of the drive circuit 05; the other end of the third resistor R3, one end of the second capacitor C2, and one end of the second resistor R2 are connected to the control circuit 01; the other end of the second resistor R2, the other end of the second capacitor C2, and the other end of the fourth resistor R4 are grounded.

[0063] In this embodiment, the control circuit 01 can input a driving signal through the MT_DRIVER terminal and receive a feedback signal through the FB terminal. Once the current value fed back from the FB terminal exceeds the preset current value, the driving circuit 05 can be controlled to stop working, which plays a protective role. In this embodiment, when the control circuit 01 inputs a driving signal, the first NMOS tube Q1 and the second NMOS tube Q2 are turned on, and the driving motor M starts to work. When there is no input to the control circuit 01, the first NMOS tube Q1 and the second NMOS tube Q2 are turned off, and the driving motor M stops working. When the driving motor M is blocked, the abnormal current can be output to the control circuit 01 through the third resistor R3, and the control circuit 01 can control the driving circuit 05 to stop working. In this embodiment, the driving signal can be a PWM signal with different duty cycles to control the voltage at both ends of the driving motor M to change, thereby controlling the speed of the driving motor M to change. The larger the duty cycle, the larger the average voltage at both ends of the driving motor M, and the higher the speed. The smaller the duty cycle, the smaller the average voltage at both ends of the driving motor M, and the lower the speed.

[0064] Further, in an embodiment of the present invention, if Figure 4 and Figure 6 As shown, the charging circuit 07 includes a charging chip U2, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5, a transient voltage suppressor TVS and a fuse F1;

The charging chip U2 can convert the input power supply voltage into a charging voltage suitable for charging the battery 03, and output it to the battery 03 through the BAT pin of the charging chip U2. During the charging process, the transient voltage suppression tube TVS can suppress the surge of the external power supply voltage, the fifth capacitor C5 can maintain the stability of the charging voltage output, and the charging current can be adjusted by setting the resistance value of the seventh resistor R7 connected to the PROG pin. The fuse F1 can be blown when the current input from the external power supply is too large to protect the safety of the charging chip U2 and the battery 03. When the battery 03 is fully charged, the charging chip U2 detects that the battery 03 is fully charged through the STDBY terminal, and then outputs a low level and inputs it to the CE pin of the charging chip U2 through the CE terminal to turn off the charging of the battery 03.

[0067] Further, in an embodiment of the present invention, if Figure 5 As shown, the battery protection circuit 08 includes a battery protection chip U3, a ninth resistor R9 and a sixth capacitor C6;

[0069] It should be noted that the battery protection chip U3 can control the on / off connection between the power supply terminal of the battery protection circuit 08 and the battery 03 by controlling the internal field effect transistor.

[0070] In this embodiment, the VM1 pin, VM2 pin, VM3 pin and VM4 pin of the battery protection chip U3 are all grounded, and the GND1 pin, GND2 pin, GND3 pin and EPAD pin of the battery protection chip U3 are all connected to the negative electrode of the battery 03.

In this embodiment, the electronic digital tube DISPLAY has a clear digital display capability and can intuitively display the power level of the battery 03. Moreover, compared with other display methods (such as display screens), the electronic digital tube DISPLAY consumes less energy and will not have a significant impact on the battery life of the battery 03.
