[0030] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0031] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component can be changed at will, and the component layout may also be more complex.

[0032] The specific implementation manner of the present invention will be further described below with reference to the accompanying drawings.

[0033] Example:

[0034] The present invention discloses a vibrating water pump, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a shell 1, a one-way valve 2, a vibrator 3, a diaphragm 4, and a rigid bracket 5. The vibrator 3 is installed on the diaphragm 4 to provide vibration energy to the diaphragm 4. The diaphragm 4 is fixed to the inside of the shell 1 through the rigid bracket 5 and divides the shell 1 into a water inlet area 6 and a water outlet area 7. The one-way valve 2 is also fixed on the rigid bracket 5. The one-way valve 2 connects the water inlet area 6 and the water outlet area 7 and keeps the water flowing from the water inlet area 6 to the water outlet area 7 in one direction.

[0035] In a preferred embodiment of this solution, the vibrator 3 is a vibration coil, which is an existing structure and can be understood by referring to a speaker. Its implementation principle is to generate vibration through electrical energy, which drives the diaphragm 4 to vibrate, and the vibration of the diaphragm 4 will achieve left and right deviation.

[0036] The one-way valve 2 is a Tesla valve, and its structure is as follows Figure 4 As shown, it is unidirectional, and water can flow in one direction relatively smoothly, but it is difficult to flow in the opposite direction.

[0037] Working Principle: When the vibrator 3, the working component, vibrates, it drives the diaphragm 4 to move. When the diaphragm 4 moves forward, the check valve 2 closes (stops reverse flow), pushing the water forward. The water is then pushed out of the water outlet area 7 by the diaphragm 4. When the diaphragm 4 moves backward, the check valve 2 opens (conducts), and the water flows out of the check valve 2 and into the water outlet area 7. This repeated action generates a continuous water flow.

[0038] In this solution, the housing 1 adopts a circular pipe structure, but it can also be in other shapes, such as square.

[0039] Based on the above embodiment, there are many options for the vibrator 3, such as using piezoelectric ceramics. Generally speaking, for lower power, a dynamic coil structure can be used, while for higher power, piezoelectric ceramics can be used. The power here refers to the electrical power consumed by the vibrator 3.

[0040] In the above solution, the vibrator 3 is assembled in the middle of the diaphragm 4, and the vibrator 3 is fixed on the rigid bracket 5. In this way, the vibrator 3 is installed more stably and reliably, and the driving of the diaphragm 4 is also more efficient.

[0041] Based on the above solution, alternative solutions are possible for the one-way valve 2. For example, the one-way valve 2 may be an elastic diaphragm 4-type valve or a steel ball one-way valve 11. For an elastic diaphragm 4-type valve, refer to the diaphragm 4 structure on the mouth of a Scream beverage bottle. Alternatively, a diaphragm 4-type one-way valve 2 with a spring metal plate structure offers excellent sealing performance and a faster response time when using a properly elastic spring plate.

[0042] In addition, the one-way valve 2 can also adopt a steel ball one-way valve 11, and this structure can refer to Figure 7 As shown. For this structure, it needs to be used vertically, using gravity, so that the steel ball is blocked by gravity to the lower through hole of the shell 1, and the water flow can push the steel ball to flow and achieve cutoff in the other direction. Therefore, the one-way valve 2 is installed to Figure 1 When the housing 1 is shown, the housing 1 needs to be used vertically to keep the one-way valve 2 in a vertical state.

[0043] Specifically, the vibrator 3 is connected to a driving circuit 10, which generates an alternating driving signal, which is a PWM wave. Figure 5 and Figure 6As shown. Preferably, the drive circuit 10 is also connected to a microcontroller 9, which outputs a PWM wave to the drive circuit 10. The drive circuit 10 also feeds back current to the microcontroller 9 for current detection. The microcontroller 9 is a single-chip microcomputer module. "CURRENT" in the figure represents the current feedback signal, which is used for current sampling by the single-chip microcomputer. The microcontroller 9 adjusts the duty cycle of the PWM wave based on the current detected to adjust the vibration power output, thereby controlling the water flow or water pressure.

[0044] A bridge drive mode is adopted, and the single chip microcomputer generates a complementary output square wave signal with a dead zone. The square wave signal drives four power devices (NM1 to NM4) through the drive circuit 10, thereby driving the vibrator 3 (component) to do work.

[0045] The power device can be an IGBT or MOSFET. The driving circuit 10 can also use a low-current MOS tube instead of a triode. Other methods can also be used to drive the power device.

[0046] In order to ensure that the circuit can work safely and efficiently, the current of the drive circuit is detected.

[0047] On the one hand, the drive can be adjusted or stopped when the current is too large to avoid damage to the circuit and vibration components.

[0048] On the other hand, the current can be used to determine whether the vibrator is operating at its optimal efficiency point. Generally speaking, the resonance point is the optimal efficiency point. At the same time, the current can also be combined with the vibration frequency and the duty cycle of the drive signal to control the operating power of the water pump, achieving variable power drive (similar to variable frequency drive).

[0049] The control flow of the microprocessor, refer to Figure 10 As shown, the current zero point can be determined first to determine whether the water pump is started. If the water pump is not started, the PWM signal output is turned off. If the water pump is determined to be started, a PWM signal is output. Next, the current is detected to determine whether it is overcurrent (detecting whether the current exceeds a preset threshold). If so, the PWM frequency or duty cycle is adjusted. Otherwise, it can be determined whether the set operating point has been reached, that is, the PWM frequency or duty cycle is adjusted to ensure that it reaches the set value. This process continues until the adjusted PWM frequency or duty cycle reaches the set value. Otherwise, the PWM frequency or duty cycle is adjusted in a loop.

[0050] Based on the above solution, a rigid counterweight can also be installed on the vibrator 3. The rigid counterweight can be made of iron or something similar to increase the mass. This can increase the kinetic energy of the vibration. Kinetic energy is 1 / 2mv², so increasing the mass m can increase the kinetic energy. v represents the velocity.

[0051] exist Figure 1As can be seen in the figure, multiple one-way valves 2 are provided, evenly distributed around the inner wall of the shell 1 and fixed on the inner wall of the shell 1. This design can facilitate maintenance and can also increase the water flow rate. Multiple one-way valves 2 are turned on to increase the water flow rate from the one-way valve 2.

[0052] In another embodiment, the one-way valve 2 is arranged at the center of the diaphragm 4 and penetrates the diaphragm 4 and is fixed to the vibrator 3. Figure 8 and Figure 9 A simplified schematic diagram is provided for further understanding. Check valve 2 is installed at the center and fixed to the vibration-generating component. In this structural form, because the edge of the diaphragm 4 is free of check valve 2, the edge is intact, making edge assembly relatively simple. When the diaphragm 4 moves forward, the check valve 2 closes (stops reverse flow), pushing the water forward. The water is then pushed out of the water outlet area 7 by the diaphragm 4. When the diaphragm 4 moves backward, the check valve 2 opens (conducts), and water flows through the check valve 2 and out of the water outlet area 7. This repeated action generates a continuous water flow.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, any equivalent variations based on the structure, shape, or principles of the present invention are intended to be within the scope of protection of the present invention.
