[0024] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application system according to an exemplary embodiment. The application system can be used in the device drainage method of this application. The application system may include at least a drainage device and a target device.

[0025] In one specific embodiment, when the negative pressure generator includes a venturi tube, a first piezoelectric vibration module may be provided on the inner wall of the throat of the venturi tube. This first piezoelectric vibration module can be used to achieve mechanical vibration. Specifically, the first piezoelectric vibration module can be a ring-shaped piezoelectric ceramic array, which can be embedded in the inner wall of the throat of the venturi tube.

[0026] It should be noted that this specification provides method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many steps and does not represent the only execution order.

[0027] Specifically, Figure 2 This is a flowchart illustrating a device drainage method according to an exemplary embodiment. Figure 2 As shown, this drainage method can be used in electronic devices such as terminals or servers, and may specifically include the following steps: S201: Upon receiving a drainage command for the target device, obtain the current water level data corresponding to the target device.

[0028] In one specific embodiment, a drainage command can be used to instruct drainage of a target device. Specifically, the drainage command can be sent by a control module in the target device, or it can be generated when a user performs a drainage trigger operation.

[0029] In one specific embodiment, the current water level data can be used to indicate the current water level within the cavity of the target device. Specifically, a water level sensor can be installed within the cavity of the target device to acquire the current water level data. Further, the water level sensor may include a capacitance sensor; the capacitance sensor can be used to detect changes in the water level within the cavity; the capacitance sensor can predict the water level by measuring changes in capacitance.

[0030] S203: If the current water level is detected to be greater than the first preset water level, execute the first preset drainage operation based on the preset main pump.

[0031] In one specific embodiment, the first preset water level data can be set according to the actual application needs.

[0032] In one specific embodiment, the first preset drainage operation can be used to achieve a large flow rate of water discharge from the cavity of the target device.

[0033] In one specific embodiment, if the current water level is detected to be higher than a first preset water level, a preset main pump can be activated to discharge water from the target device cavity at a high flow rate, thus treating most of the accumulated water in the cavity. Specifically, after the preset main pump is activated, it can generate a strong water flow, pushing the water out of the cavity through the drainage pipe.

[0034] S205: If the current water level is detected to be less than or equal to the first preset water level, a second preset drainage operation is executed based on the negative pressure generator.

[0035] In one specific embodiment, the second preset drainage operation can be used to drain residual water from the target device cavity.

[0036] In one specific embodiment, when the current water level is detected to be less than or equal to a first preset water level, a negative pressure generator can be activated. By accelerating the water flow, the pressure inside the pipe is reduced, generating negative pressure, thereby guiding the residual water in the low-lying area to flow towards the main drainage pipe.

[0037] In one specific embodiment, when the negative pressure generator is a Venturi tube, the inlet of the Venturi tube can be connected to the fluid source of the cavity drainage system; the throat of the Venturi tube can be the water flow acceleration region, i.e., the core region for negative pressure generation; the outlet of the Venturi tube can be connected to the main drainage pipe, drawing water out of the cavity through negative pressure. It is understood that when water flows through the throat, the cross-sectional area decreases, and the flow velocity increases. According to the principles of fluid mechanics, increased flow velocity leads to decreased pressure, thereby generating negative pressure.

[0038] In a specific embodiment, the above-mentioned execution of a second preset drainage operation based on a negative pressure generator when the current water level data is detected to be less than or equal to a first preset water level data may include: If the current water level is detected to be less than or equal to the first preset water level, the preset main pump is shut down and the current residual water volume is acquired. If the current residual water volume is greater than or equal to the preset residual water volume, the second preset drainage operation is executed based on the negative pressure generator.

[0039] In one specific embodiment, the current residual water volume data can be used to indicate the amount of residual water inside the target device. The current residual water volume data may include current residual water volume data or current residual water level data.

[0040] In one specific embodiment, a weight sensor can be installed within the target device. Based on the weight sensor, the current weight data of the target device is acquired, and the current residual water volume is determined based on the difference between the target device's reference weight data and the aforementioned current weight data. Specifically, the reference weight data can be obtained by measuring the target device before water use.

[0041] In one specific embodiment, the preset residual water volume data can be set according to actual application needs, and this disclosure does not limit it.

[0042] In one specific embodiment, when the current residual water volume is greater than or equal to a preset residual water volume, a negative pressure generator can be activated to create negative pressure within the cavity of the target device, thereby guiding residual water in the low-lying area towards the main drainage pipe. Specifically, when the negative pressure generator is a Venturi negative pressure generator, it includes a Venturi tube, which can reduce the pressure within the pipe by accelerating the water flow, thus generating negative pressure. It can be understood that when water flows through the throat, the cross-sectional area decreases, and the flow velocity increases. According to fluid mechanics principles, increased flow velocity leads to decreased pressure, thereby generating negative pressure.

[0043] In one specific embodiment, when the negative pressure generator includes a venturi tube, a first piezoelectric vibration module may be provided on the inner wall of the throat of the venturi tube. This first piezoelectric vibration module can be used to achieve mechanical vibration. Specifically, the first piezoelectric vibration module can be a ring-shaped piezoelectric ceramic array, which can be embedded in the inner wall of the throat of the venturi tube.

[0044] In one specific embodiment, the above method may further include: During the execution of the second preset drainage operation, the current sewage viscosity data is acquired; Accordingly, the above-mentioned second preset drainage operation based on the negative pressure generator may include: If the current sewage viscosity data is detected to be greater than the first preset viscosity data, the second preset drainage operation is executed based on the first piezoelectric vibration module and the venturi tube.

[0045] In one specific embodiment, the current wastewater viscosity data can be used to indicate the current viscosity of the water within the target device cavity. It is understood that the higher the current wastewater viscosity data, the higher the viscosity of the water within the target device cavity.

[0046] In one specific embodiment, a liquid viscosity sensor can be installed inside the cavity of the target device; the current sewage viscosity data can be obtained based on the liquid viscosity sensor.

[0047] In one specific embodiment, the first preset viscosity data can be set according to the actual application needs, and this disclosure does not limit it.

[0048] In one specific embodiment, when the current sewage viscosity data is detected to be greater than the first preset viscosity data, the first piezoelectric vibration module can be activated to achieve vibration stripping inside the Venturi tube during the residual water discharge process, which can prevent the adhesion of viscous stains inside the throat and improve the efficiency of cleaning water accumulation in the groove.

[0049] In one specific embodiment, the above-mentioned execution of a second preset drainage operation based on the first piezoelectric vibration module and the venturi tube when the current sewage viscosity data is detected to be greater than the first preset viscosity data may include: When the current sewage viscosity data is detected to be greater than the first preset viscosity data and less than or equal to the second preset viscosity data, the first piezoelectric vibration module is controlled to vibrate based on the first preset frequency. If the current sewage viscosity data is detected to be greater than the second preset viscosity data, the first piezoelectric vibration module is controlled to vibrate based on the second preset frequency.

[0050] In one specific embodiment, the second preset viscosity data can be greater than the first preset viscosity data. Specifically, the second preset viscosity data can be set according to actual application needs, and this disclosure does not limit it.

[0051] In one specific embodiment, the first preset frequency may be less than the second preset frequency. For example, the first preset frequency may be 100Hz; the second preset frequency may be 120Hz.

[0052] In one specific embodiment, if the current wastewater viscosity is detected to be greater than a second preset viscosity, the first piezoelectric vibration module can be controlled to vibrate at a second preset frequency based on the venturi tube, and a preset auxiliary pump can be activated to further discharge residual water. It is understood that when membrane peeling accelerates, the flow rate of the preset auxiliary pump can be increased to assist in the drainage effect.

[0053] S207: If, during the execution of the second preset drainage operation, it is detected that the negative pressure generated by the negative pressure generator is less than the preset negative pressure, the second preset drainage operation is executed based on the negative pressure generator and the preset auxiliary pump.

[0054] In one specific embodiment, the preset negative pressure can be set according to the actual application needs, and this disclosure does not limit it.

[0055] In one specific embodiment, if the negative pressure generated by the negative pressure generator is found to be lower than the preset negative pressure during the second preset drainage operation, the negative pressure generator can be activated and the preset auxiliary pump can be activated simultaneously to achieve efficient discharge of residual water. It can be understood that the negative pressure generator and the preset auxiliary pump can extract small amounts of accumulated water that the main pump cannot completely discharge, especially residual water located in low-lying areas of the cavity.

[0056] In one specific embodiment, if the current water level is detected to be lower than the second preset water level during the execution of the second preset drainage operation, the second preset drainage operation can be executed based on a negative pressure generator and a preset auxiliary pump. The second preset water level can be lower than the first preset water level. Specifically, the second preset water level can be set according to actual application needs, and this disclosure does not limit it.

[0057] In one specific embodiment, the above method may further include: Upon receiving a water film removal command, the second piezoelectric vibration module is controlled to vibrate at a third preset frequency to cause the water film on the cavity wall to peel off.

[0058] In one specific embodiment, the water film removal command can be used to instruct the drainage device to perform a water film removal operation within the target device cavity. Specifically, the water film removal command can be generated by the user or after detecting the completion of a second preset drainage operation.

[0059] In one specific embodiment, the second piezoelectric vibration module may include a piezoelectric ceramic diaphragm. Specifically, the piezoelectric ceramic diaphragm may be disposed at the lowest point within the cavity of the target device, and the piezoelectric ceramic diaphragm may be attached to the cavity wall of the target device.

[0060] In one specific embodiment, the driving signal corresponding to the third preset frequency has a larger amplitude and a higher vibration amplitude, which can be used to overcome the adhesion force of water droplets. The third preset frequency can be set according to the actual application needs, and this disclosure does not limit it. For example, the third preset frequency can be 100Hz.

[0061] In one specific embodiment, upon receiving a water film removal instruction, currently in the initial stage (i.e., the water film peeling stage), the second piezoelectric vibration module can be controlled to vibrate based on a third preset frequency to cause the water film on the cavity wall to peel off.

[0062] In one specific embodiment, the second piezoelectric vibration module can be controlled by a drive circuit, and a third preset frequency signal can be generated by a controller and transmitted to the second piezoelectric vibration module. Taking a piezoelectric ceramic vibrating membrane as an example, the piezoelectric ceramic vibrating membrane will generate large-amplitude mechanical vibration, which helps to peel off larger water droplets on the cavity wall; through low-frequency vibration, the water droplets will detach from the cavity wall due to inertia, thereby reducing the thickness of the water film.

[0063] In the above embodiments, by controlling the second piezoelectric vibration module to vibrate based on a third preset frequency upon receiving a water film removal command, the adhesion force between the water droplet and the cavity wall can be overcome, causing the water droplet to detach from the cavity wall, thereby achieving effective removal of the water film inside the target device.

[0064] In one specific embodiment, after controlling the second piezoelectric vibration module to vibrate based on a third preset frequency, the method may further include: The second piezoelectric vibration module is controlled to vibrate based on a fourth preset frequency to atomize the water film on the cavity wall.

[0065] In one specific embodiment, the fourth preset frequency can be greater than the third preset frequency. The driving signal amplitude corresponding to the fourth preset frequency is relatively small, resulting in subtle vibrations, which can be used for water film atomization. Specifically, the fourth preset frequency can be set according to actual application needs, and this disclosure does not limit it. For example, the fourth preset frequency can be 20kHz.

[0066] In one specific embodiment, after the water film stripping stage, the current stage can be a later stage (i.e., the atomization stage), where the system can switch to a fourth preset frequency to atomize the remaining water film. Specifically, the signal of the fourth preset frequency can be generated by the controller and transmitted to the second piezoelectric vibration module.

[0067] In the above embodiment, by controlling the second piezoelectric vibration module to vibrate based on a fourth preset frequency, the water droplets undergo tiny deformation on the surface caused by the vibration. When the water droplets are subjected to sufficient high-frequency vibration, they will be stretched and broken, eventually forming tiny water mist particles, thereby achieving further effective removal of the water film inside the target device.

[0068] In one specific embodiment, the above method may further include: During the vibration of the second piezoelectric vibration module based on the third preset frequency, water droplet detachment index data are acquired. Accordingly, the above-mentioned control of the second piezoelectric vibration module based on the fourth preset frequency vibration may include: When the water droplet detachment index data is greater than the preset detachment index data, the second piezoelectric vibration module is controlled to vibrate based on the fourth preset frequency.

[0069] In one specific embodiment, the water droplet detachment index data can characterize the amount of water droplet detachment during a vibration process based on a third preset frequency.

[0070] In one specific embodiment, the preset departure index data can be set according to the actual application needs, and this disclosure does not limit it.

[0071] In the above embodiments, by controlling the second piezoelectric vibration module to vibrate based on a fourth preset frequency when the water droplet detachment index data is greater than the preset detachment index data, energy-saving effect can be achieved while ensuring the water film removal effect.

[0072] In one specific embodiment, the above method may further include: During the vibration of the second piezoelectric vibration module based on the fourth preset frequency, the current atomized particle size data is acquired; If the current atomized particle size is detected to be smaller than the preset atomized particle size, a drying operation is performed.

[0073] In one specific embodiment, the current atomization particle size data can be used to indicate the particle size of the currently atomized water droplets.

[0074] In one specific embodiment, the preset atomization particle size data can be set according to actual application needs, and this disclosure does not limit it.

[0075] In one specific embodiment, if the current atomized particle size data is detected to be smaller than the preset atomized particle size data, a drying operation can be performed based on the drying module, and the tiny water mist can be carried away by the drying airflow.

[0076] In the above embodiments, by performing a drying operation when the current atomized particle size data is detected to be smaller than the preset atomized particle size data, the water film removal effect can be further improved, and thorough drainage can be achieved.

[0077] In the above embodiments, upon receiving a drainage command for the target device, the current water level data corresponding to the target device is obtained, enabling the detection of the current water level within the target device's cavity. If the current water level data is detected to be greater than a first preset water level data, a first preset drainage operation is executed based on a preset main pump, achieving high-flow drainage for the target device. Next, if the current water level data is detected to be less than or equal to the first preset water level data, a second preset drainage operation is executed based on a negative pressure generator. This generates negative pressure, guiding residual water in low-lying areas towards the main drainage pipe, thus discharging residual water. Then, if the negative pressure generated by the negative pressure generator is detected to be less than the preset negative pressure during the execution of the second preset drainage operation, a second preset drainage operation is executed based on the negative pressure generator and a preset auxiliary pump. The preset auxiliary pump further enhances the suction capacity, clearing small accumulations of water, thereby improving the device's drainage effect.
