[0001] The present application relates to the field of oral cleaning technology, and in particular to a water flosser and a control method for the water flosser. Background Art

[0002] With improved living standards, people's awareness of oral care has gradually increased, and a wider variety of oral cleaning tools are now available on the market. Among them, oral irrigators, as an alternative to traditional dental floss, have become a must-have small appliance in households. Their basic working principle is that a pump draws water from a tank and sprays it through a nozzle, releasing high-pressure pulses of water hundreds or even thousands of times per minute. This pulses cleans food debris and plaque from between teeth, massages gums, and improves the oral environment.

[0003] In the relevant technical field, since the overall structure of the water flosser is relatively compact, the pump body can be set as a rotor pump. However, when the rotor and the casing of the rotor pump are accidentally stuck, the motor is likely to burn out.

[0006] Based on the above embodiment, when the detection device detects the detection value of the factor affecting the jamming of the spherical rotor pump or the detection value corresponding to the jamming of the spherical rotor pump, the controller controls the driving device to reduce the operating speed or shut down, which can reduce the probability of the spherical rotor pump getting stuck; and when the spherical rotor pump gets stuck abnormally, the controller can control the driving device to shut down to prevent the driving device from burning out, which can make the driving device have a longer service life, and thus the water flosser can have a longer service life.

[0037] Referring to Figures 1 and 2, an embodiment of the present application provides a water flosser 1, including a device body 11, a detection device 12 (refer to Figure 3) and a controller 13 (refer to Figure 3). The device body 11 includes a shell 111 and a liquid storage tank 112, a spherical rotor pump 113, a driving device 114, a pipeline 115 and a battery 116 arranged on the shell 111.

[0038] The housing 111 is configured to protect the liquid tank 112, the spherical rotor pump 113, the drive device 114, and the pipeline 115, thereby reducing the probability of damage to the liquid tank 112, the spherical rotor pump 113, the drive device 114, and the pipeline 115, thereby extending the service life of the oral irrigator 1. The housing 111 also allows the liquid tank 112, the spherical rotor pump 113, the drive device 114, and the pipeline 115 to form a whole, making it easier for the user to use the oral irrigator 1. The housing 111 has a liquid spray port 111A, and the pipeline 115 connects the liquid tank 112, the spherical rotor pump 113, and the liquid spray port 111A. The spherical rotor pump 113 pumps the liquid in the liquid tank 112 out of the liquid spray port 111A through the pipeline 115 to clean the user's oral cavity. The housing 111 can be made of metal or plastic. For example, the shell 111 can be made of plastic to make the shell 111 lighter, thereby making the entire oral irrigator 1 lighter, and making it easier for the user to hold the oral irrigator 1. Specifically, the shell 111 can be integrally formed to give the shell 111 a higher structural strength, thereby reducing the probability of damage to the shell 111 and allowing the oral irrigator 1 to have a longer service life. In the embodiment of the present application, there is no specific limitation on the material of the shell 111.

[0039] The liquid storage tank 112 is used to store liquid so that the user can use the oral irrigator 1 without the pipeline, thereby improving the convenience of the user in using the oral irrigator 1.

[0040] The spherical rotor pump 113 changes the working volume through the relative movement between the rotor and the housing, and discharges the liquid by the squeezing effect of the rotating rotor, while leaving space on the other side to form a low pressure, so that the liquid is continuously sucked in, so that the liquid in the liquid storage tank 112 can be pumped out to clean the user's mouth.

[0041] The drive device 114 is configured to drive the spherical rotor pump 113 to rotate. For example, the drive device 114 may include a motor and a reducer connected to the motor. The reducer may be used to reduce the speed of the motor to drive the spherical rotor pump 113. For example, the drive device 114 may also include a motor that directly drives the spherical rotor pump 113. In the embodiments of the present application, the specific form of the drive device 114 is not specifically limited.

[0042] The battery 116 is connected to the driving device 114 and the battery 116 , and is configured to supply power to the driving device 114 and the battery 116 . The battery 116 may be a rechargeable and dischargeable battery 116 .

[0043] The detection device 12 is configured to detect a detection value of a factor affecting the stuck rotation of the spherical rotor pump 113 or a detection value corresponding to the stuck rotation of the spherical rotor pump 113;

[0044] The controller 13 is connected to the detection device 12 and the driving device 114 , and is configured to control the operation of the driving device 114 according to the detection value of the detection device 12 .

[0045] In an embodiment of the present application, when the detection device 12 detects a detection value of a factor affecting the jamming of the spherical rotor pump 113 or a detection value corresponding to the jamming of the spherical rotor pump 113, the controller 13 controls the driving device 114 to reduce the operating speed or shut down, which can reduce the probability of the spherical rotor pump 113 getting stuck; and when the spherical rotor pump 113 gets stuck abnormally, the controller 13 can control the driving device 114 to shut down to prevent the driving device 114 from burning out, which can make the driving device 114 have a longer service life, and thus the water flosser 1 can have a longer service life.

[0046] Please refer to Figures 1 and 2. In a specific embodiment, when the detection value deviates from the preset value, the controller 13 can control the driving device 114 to shut down, thereby protecting the driving device 114. Exemplarily, the deviation of the detection value from the preset value can be at least one of the detection temperature being greater than or equal to the preset temperature, the detection liquid level being lower than or equal to the preset liquid level, the detection flow rate being lower than or equal to the preset flow rate, and the detection current being less than or equal to the preset current. When at least one of the above states occurs, the controller 13 can control the driving device 114 to shut down to prevent the driving device 114 from being burned out, thereby allowing the driving device 114 to have a longer service life, so that the oral irrigator 1 has a longer service life.

[0047] Referring to Figures 1 and 2, in a specific embodiment, when the detection value deviates from a preset value, the controller 13 controls the driving device 114 to operate for a first period of time, and then controls the driving device 114 to stop or slow down, so that the spherical rotor pump 113 can draw liquid from the liquid storage tank 112 within the first period of time to reduce the residual liquid in the liquid storage tank 112. For example, the first period of time can be 30 seconds, 1 minute, 1 minute 30 seconds, or 2 minutes.

[0048] Referring to Figures 1 and 2, in a specific embodiment, when the detected value deviates from a preset value, the controller 13 controls the driving device 114 to stop operating for a second time period, thereby allowing the spherical rotor pump 113 to cool down during the second time period, so that the user can continue to use the oral irrigator 1 for oral hygiene after the second time period. For example, the second time period can be 1 hour, 1 hour and 30 minutes, or 2 hours.

[0049] Referring to Figures 1 and 2, in a specific embodiment, within the second time range, when the controller 13 receives a signal to start the drive device 114, it controls the drive device 114 to remain in a stopped state, so as to ensure that the spherical rotor pump 113 will not be started again within the second time range after the detection value deviates from the preset value, so as to reduce the probability of the spherical rotor pump 113 getting stuck, thereby reducing the probability of the drive device 114 burning out.

[0050] Referring to Figures 1 and 2, in a specific embodiment, when the detection value deviates from the preset value and remains for a third time period, the controller 13 controls the driving device 114 to shut down, so that the driving device 114 can be shut down within the third time period to prevent the driving device 114 from burning out. For example, the third time period can be 30 seconds, 1 minute, 1 minute 30 seconds, or 2 minutes.

[0051] Referring to Figures 1 and 2, in a specific embodiment, when the detection value deviates from the preset value, the controller 13 controls the driving device 114 to decelerate and operate for a fourth time period, and then controls the driving device 114 to stop. This eliminates the situation where the liquid level in the liquid storage tank 112 decreases due to the user's posture, causing the spherical rotor pump 113 to idle, thereby improving the accuracy of the detection results of the detection device 12. For example, the fourth time period can be 30 seconds, 1 minute, 1 minute and 30 seconds, or 2 minutes.

[0052] Referring to Figures 1 and 2 , in a specific embodiment, when the detected value deviates from a preset value, the controller 13 controls the drive device 114 to decelerate for a fifth time period, and then controls the drive device 114 to resume normal operation. The fifth time period of slow operation can cool the spherical rotor pump 113, thereby reducing the probability of the spherical rotor pump 113 getting stuck. For example, the fifth time period can be 30 seconds, 1 minute, 1 minute 30 seconds, or 2 minutes.

[0053] 1 and 2 , in a specific embodiment, when the detection value deviates from the preset value and upon receiving a signal to start the drive device 114, the controller 13 controls the drive device 114 to remain in a shutdown state to prevent the spherical rotor pump 113 from being started a second time when the detection value deviates from the preset value, thereby reducing the probability of the spherical rotor pump 113 getting stuck and reducing the probability of the drive device 114 burning out.

[0054] Referring to Figures 1 and 2 , in a specific embodiment, when the detected value deviates from a preset value, the controller 13 controls the driving device 114 to reduce the operating speed or shut down within a sixth time period, thereby improving the user experience. For example, the sixth time period can be 30 seconds, 1 minute, 1 minute 30 seconds, or 2 minutes.

[0055] Please refer to Figures 1 and 2. In a specific embodiment, when the detection device 12 detects that at least one of the temperature of the spherical rotor pump 113 is greater than or equal to the preset temperature, the liquid level of the liquid storage tank 112 is lower than or equal to the preset liquid level, the flow of the pipeline 115 is lower than or equal to the preset flow, and the current of the drive device 114 is greater than or equal to the preset current, the controller 13 controls the drive device 114 to shut down, thereby reducing the probability of the spherical rotor pump 113 being stuck due to excessive dry-running temperature, so that the drive device 114 can be protected, thereby preventing damage to the drive device 114; and when the spherical rotor pump 113 is abnormally stuck, the controller 13 can also control the drive device 114 to shut down to prevent the drive device 114 from burning out, both of which can make the drive device 114 have a longer service life, and thus the water flosser 1 can have a longer service life.

[0056] Please refer to Figures 2 and 3. In a specific embodiment, the detection device 12 includes a temperature detection element 121, which is configured to detect the temperature of the spherical rotor pump 113; the controller 13 obtains the detection temperature of the spherical rotor pump 113 via the temperature detection element 121. When the detection temperature is greater than or equal to the first preset temperature, it indicates that the spherical rotor pump 113 is stuck, and the controller 13 controls the driving device 114 to shut down, thereby preventing the driving device 114 from being burned out, so that the driving device 114 has a longer service life, and the oral irrigator 1 has a longer service life.

[0057] Specifically, the temperature detection element 121 can be disposed on the outer surface of the housing of the spherical rotor pump 113. The temperature detection element 121 includes at least one of a thermistor sensor, a thermocouple sensor, an aluminum thermistor temperature sensor, or a digital output sensor. In the embodiments of the present application, the form of the temperature detection element 121 is not specifically limited.

[0058] Please refer to Figures 2 and 3. In a specific embodiment, the shell of the spherical rotor pump 113 has a guide groove (not shown in the figure) connected to the cavity, and the temperature detection element 121 can be staggered with the guide groove to prevent the liquid overflowing from the cavity from contacting the temperature detection element 121, thereby improving the temperature detection accuracy of the temperature detection element 121.

[0059] Referring to Figures 2-5 , in a specific embodiment, the spherical rotor pump 113 includes a first housing 1131, a second housing 1132, and an inner rotor 1133. A chamber 113A is defined between the first and second housings 1131, 1132. The inner rotor 1133 is disposed within the chamber 113A. The inner rotor 1133 has a connecting shaft 11331. The first housing 1131 has a connecting hole 1131A. The drive mechanism 114 has a drive shaft 1141, which passes through the connecting hole 1131A and is in transmission connection with the connecting shaft 11331. This allows the drive mechanism 114 to drive the inner rotor 1133 to rotate, thereby pumping liquid from the liquid reservoir 112 to clean the user's oral cavity. It is understood that the connecting shaft 11331 can also pass through the connecting hole 1131A and be in transmission connection with the drive shaft 1141. In this embodiment of the present application, the connection between the connecting shaft 11331 and the drive shaft 1141 is not specifically limited.

[0060] 2-5 , it can be understood that the temperature detection element 121 can be disposed on the outer surface of the second housing 1132 , which can prevent liquid from contacting the temperature detection element 121 when liquid leaks from the connection hole 1131A, thereby improving the accuracy of temperature detection.

[0061] Please refer to Figures 2-5. It can be understood that the temperature detection element 121 is also arranged on the outer surface of the first shell 1131, which can facilitate the routing of the temperature detection element 121, reduce wiring costs, and reduce the difficulty of assembling the spherical rotor pump 113, thereby improving the assembly efficiency of the oral irrigator 1.

[0062] Please refer to Figures 2-5. In a specific embodiment, the first shell 1131 includes a first cavity portion 11311 and a first substrate portion 11312. The first substrate portion 11312 is connected to the outer periphery of the first cavity portion 11311 at one end facing the second shell 1132. The second shell 1132 includes a second cavity portion 11321 and a second substrate portion 11322. The second substrate portion 11322 is connected to the outer periphery of the second cavity portion 11321 facing the first shell 111. The first substrate portion 11312 and the second substrate portion 11322 are connected to each other. The temperature detection element 121 is arranged on the outer periphery of the first cavity portion 11311, which can make the temperature detection element 121 closer to the inner rotor 1133, thereby improving the accuracy of temperature detection.

[0063] It is understandable that the temperature detection element 121 may also be disposed on the outer periphery of the second cavity portion 11321 , so that the temperature detection element 121 is closer to the inner rotor 1133 , thereby improving the accuracy of temperature detection.

[0064] Please refer to Figures 2-5. In a specific embodiment, a mounting groove (not shown in the figures) is provided on the outer periphery of the first shell 1131. The mounting groove is configured to install the temperature detection device 12. The distance between the bottom of the mounting groove and the inner wall of the accommodating cavity 113A is smaller than the distance between the outer periphery of other parts of the first shell 1131 and the inner wall of the accommodating cavity 113A. By using the mounting groove to install the temperature detection device 12, the contact area between the temperature detection device 12 and the shell can be increased, thereby improving the connection stability of the temperature detection device 12 and the shell; and since the mounting groove is provided, the temperature detection device 12 can be brought closer to the inner rotor 1133, thereby improving the detection accuracy of the temperature detection device 12.

[0065] It can be understood that the outer periphery of the second shell 1132 may also be provided with an installation groove (not shown in the figure) for installing the temperature detection device 12, which can also make the temperature detection device 12 closer to the inner rotor 1133, so as to improve the detection accuracy of the temperature detection device 12.

[0066] Please refer to Figures 2-5. In a specific embodiment, a sealing colloid (not shown in the figures) is provided on the outer surface of the temperature detection device 12. The sealing colloid seals the temperature detection element 121, which can improve the tightness of the connection between the temperature detection element 121 and the shell, and prevent liquid from splashing onto the temperature detection element 121, so as to improve the detection accuracy of the temperature detection element 121.

[0067] Referring to Figures 2 and 3, in a specific embodiment, when the detected temperature is greater than or equal to the second preset temperature and less than the first preset temperature, it indicates that at least one of the following conditions is about to occur: the spherical rotor pump 113 has been running for a long time or the liquid level in the liquid storage tank 112 is low. At this time, the controller 13 controls the speed of the driving device 114 to decrease so that before the detected temperature of the spherical rotor pump 113 reaches the first preset temperature, the speed of the rotor is reduced to reduce the temperature of the rotor, thereby further reducing the probability of the rotor and the housing being stuck, preventing the driving device 114 from burning out, and thus extending the service life of the driving device 114 and the service life of the oral irrigator 1. When the detected temperature is less than the second preset temperature, it indicates that the temperature of the spherical rotor pump 113 is low and the liquid level in the liquid storage tank 112 is high. The controller 13 controls the driving device 114 to maintain the current operating state, thereby providing a cleaning function for the user's oral cavity. The second preset temperature is lower than the first preset temperature.

[0068] Please refer to Figures 2 and 3. In a specific embodiment, when the rising rate of the detected temperature is greater than or equal to the preset rising rate, it indicates that at least one of the following conditions occurs: the liquid level in the liquid storage tank 112 is low, or there is no liquid in the liquid storage tank 112. The controller 13 controls the driving device 114 to shut down, thereby stopping the spherical rotor pump 113 from rotating. This can prevent the rotor of the spherical rotor pump 113 from getting stuck with the outer casing, and further prevent the driving device 114 from being burned out, so that the driving device 114 has a longer service life, and the oral irrigator 1 has a longer service life.

[0069] Please refer to Figures 2 and 3. In a specific embodiment, when the detected temperature is greater than or equal to the second preset temperature and less than the first preset temperature, it indicates that at least one of the following conditions will occur: the spherical rotor pump 113 has been running for a long time and the liquid level in the liquid storage tank 112 is low. At this time, the controller 13 controls the driving device 114 to reduce the speed within the sixth time period, so that before the detected temperature of the spherical rotor pump 113 reaches the first preset temperature, the speed of the rotor is reduced, so that the temperature of the rotor can be reduced within the sixth time period, thereby further reducing the probability of the rotor and the housing being stuck, preventing the driving device 114 from burning out, and ensuring that the driving device 114 has a longer service life, and the water flosser 1 has a longer service life. Wherein, the second preset temperature is lower than the first preset temperature.

[0070] Please refer to Figures 2 and 3. In a specific embodiment, when the rising rate of the detected temperature is greater than or equal to the preset rising rate, it indicates that at least one of the following conditions occurs: the liquid level in the liquid storage tank 112 is low, or there is no liquid in the liquid storage tank 112. The controller 13 controls the driving device 114 to reduce the operating speed or control the driving device 114 to shut down within the sixth time period, which can prevent the rotor of the spherical rotor pump 113 from getting stuck with the outer casing, and further prevent the driving device 114 from being burned out, so that the driving device 114 has a longer service life, and the oral irrigator 1 has a longer service life.

[0071] Referring to Figures 2 and 3 , in a specific embodiment, when the detected temperature rise rate is greater than a preset rise rate and the detected temperature is less than a third preset temperature, indicating that the spherical rotor pump 113 will idle when the drive device 114 is just started, the drive device 114 is prevented from being shut down at this time, thereby improving the accuracy of the controller 13 controlling the operation of the drive device 114. The third preset temperature is less than the first preset temperature and less than or equal to the second preset temperature.

[0072] Please refer to Figures 2 and 3. In a specific embodiment, when the detected temperature is greater than or equal to the first preset temperature, the controller 13 controls the drive device 114 to maintain the current operating state for a first period of time, so that the spherical rotor pump 113 can continue to operate for the first period of time, thereby completely pumping out the liquid in the liquid storage tank 112 to reduce the probability of liquid residue in the liquid storage tank 112.

[0073] Please refer to Figures 2 and 3. In a specific embodiment, when the rising rate of the detected temperature is greater than or equal to the preset rising rate, the controller 13 controls the driving device 114 to maintain the current operating state for a sixth period of time, so that the spherical rotor pump 113 can continue to operate for the sixth period of time, so that when the liquid level in the liquid storage tank 112 is low, all the liquid in the liquid storage tank 112 can be pumped out to reduce the probability of liquid residue in the liquid storage tank 112.

[0074] Please refer to Figures 2 and 3. In a specific embodiment, when the detected temperature is greater than or equal to the first preset temperature, the controller 13 controls the driving device 114 to shut down to prevent the spherical rotor pump 113 from getting stuck, and the controller 13 controls the prompt device to issue a prompt message to remind the user that the temperature of the spherical rotor pump 113 is too high, and maintains the shutdown state for a second period of time to facilitate the heat dissipation of the spherical rotor pump 113; further, within the second period of time, the driving device 114 is prevented from being started again, thereby reducing the probability of the rotor pump getting stuck, thereby reducing the probability of the driving device 114 burning out, and thereby making the driving device 114 have a longer service life, so that the oral irrigator 1 has a longer service life.

[0075] Please refer to Figures 2 and 3. In a specific embodiment, if the detected temperature is greater than or equal to the first preset temperature, within the second time period after the controller 13 controls the drive device 114 to shut down, the user sends a start signal to the control through the operation panel, the controller 13 controls the drive device 114 to remain in the shutdown state, and controls the prompt device to send a prompt message to the user to prompt the user that the temperature of the spherical rotor pump 113 is too high.

[0076] Referring to Figures 2 and 3 , in a specific embodiment, before the drive device 114 is activated, if the detected temperature is less than a third preset temperature, the drive device 114 is controlled to operate to ensure that the temperature of the spherical rotor pump 113 is low. This reduces the probability of the spherical rotor pump 113 getting stuck due to idling and heating when the spherical rotor pump 113 is driven, thereby facilitating oral cleansing using the oral irrigator 1. If the detected temperature is greater than or equal to the third preset temperature, the drive device 114 is controlled to remain in a stopped state and a prompt is issued to inform the user that the temperature of the spherical rotor pump 113 is high. The third preset temperature is lower than the first preset temperature.

[0077] Please refer to Figures 2 and 3. In a specific embodiment, when the detected temperature is greater than or equal to the first preset temperature, the controller 13 controls the driving device 114 to maintain the running state and lasts for a first period of time, and then controls the speed of the driving device 114 to gradually decrease until it stops, thereby improving the user experience.

[0078] Please refer to Figures 2 and 3. In a specific embodiment, the oral irrigator 1 also includes a prompt device (not shown in the figure). The prompt device is arranged in the housing 111 and is connected to the controller 13. It is configured to issue a prompt message when the detection temperature obtained by the controller 13 is greater than or equal to the first preset temperature; and issue a prompt message when the detection temperature obtained by the controller 13 is greater than or equal to the second preset temperature and less than the first preset temperature; wherein the second preset temperature is less than the first preset temperature, and the prompt message and the prompt message include at least one of light information and sound information. Specifically, the light information can be emitted by a light emitting diode or a display screen. In the embodiment of the present application, there is no specific limitation on the specific form of the light information. Specifically, the sound information can be emitted by a power amplifier.

[0079] Please refer to Figures 2 and 6. In a specific embodiment, the detection device 12 includes a liquid level detection component 122, which is configured to detect the liquid level of the liquid storage tank 112; the controller 13 can obtain the detected liquid level through the liquid level detection component 122. When the detected liquid level is lower than or equal to the first preset liquid level, the controller 13 controls the driving device 114 to shut down to prevent the driving device 114 from continuing to drive the spherical rotor pump 113 to operate, thereby reducing the probability of the spherical rotor pump 113 being stuck due to excessive dry-running temperature, thereby reducing the probability of the driving device 114 burning out, so that the driving device 114 can have a longer service life, so that the oral irrigator 1 has a longer service life.

[0080] Please refer to Figures 2 and 6. In a specific embodiment, the liquid level detection component 122 includes two resistance wires 1221 and a float 1222. The two resistance wires 1221 are both arranged in the liquid storage tank 112. The two resistance wires 1221 are arranged at intervals and both extend along the height direction of the liquid storage tank 112, and both are connected to the controller 13; the float 1222 is arranged in the liquid storage tank 112 and contacts the two resistance wires 1221, and is configured to follow the liquid level movement of the liquid storage tank 112; when the liquid level in the liquid storage tank 112 changes, the float 1222 moves with the liquid level and along the resistance wire 1221, so that the resistance of the resistance wire 1221 changes, so that the controller 13 can correspond to the liquid level change in the liquid storage tank 112 according to at least one change in the resistance change of the resistance wire 1221, the voltage change at both ends of the resistance wire 1221, and the current change flowing through the resistance wire 1221.

[0081] When the detected liquid level is lower than or equal to the first preset liquid level, the liquid level in the liquid storage tank 112 is low, which can easily cause the spherical rotor pump 113 to run idle. At this time, the controller 13 controls the driving device 114 to shut down, thereby reducing the probability of the spherical rotor pump 113 running idle, thereby reducing the probability of the driving device 114 burning out, thereby extending the service life of the driving device 114 and, in turn, extending the service life of the oral irrigator 1. The controller 13 also issues a prompt message to the user to inform the user that the liquid level in the liquid storage tank 112 is low, thereby facilitating the user to replenish the liquid in the liquid storage tank 112. When the detected liquid level is higher than the first preset liquid level and lower than or equal to the second preset liquid level, the controller 13 controls the driving device 114 to reduce the operating speed and issues a prompt message to inform the user that the liquid in the liquid storage tank 112 is about to run out. When the detected liquid level is higher than the second preset liquid level, the controller 13 controls the driving device 114 to maintain the current operating state. The second preset liquid level is higher than the first preset liquid level.

[0082] Please refer to Figures 2 and 7. In a specific embodiment, the liquid level detection component 122 also includes a plurality of capacitive detection films 1223 and an internal conductor 1224. The plurality of capacitive detection films 1223 are arranged at intervals on the outer surface of the liquid storage tank 112; the plurality of capacitive detection films 1223 include at least a first detection film 12231 and a second detection film 12232, and the first detection film 12231 and the second detection film 12232 are arranged at intervals along the height direction of the liquid storage tank 112; the internal conductor 1224 is arranged in the liquid storage tank 112; wherein, the liquid level in the liquid storage tank 112 is in contact with the first detection film 12231 as a first preset liquid level, and the liquid level in the liquid storage tank 112 is in contact with the second detection film 12232 as a second preset liquid level, and the second preset liquid level is higher than the first preset liquid level.

[0083] When the liquid level in the liquid storage tank 112 changes, the liquid surface will contact one of the multiple capacitive detection films 1223, so that the capacitance value between the corresponding capacitive detection film 1223 and the internal conductor 1224 changes, so that the controller 13 can receive the corresponding electrical signal to detect the liquid level. When the detected liquid level is lower than or equal to the first preset liquid level, it indicates that the liquid in the liquid storage tank 112 is exhausted, which may easily cause the spherical rotor pump 113 to idle. The controller 13 controls the driving device 114 to shut down, so that the spherical rotor pump 113 shuts down, thereby cooling the spherical rotor pump 113, reducing the probability of the spherical rotor pump 113 getting stuck, and reducing the probability of the driving device 114 burning out, thereby making the driving device 114 have a longer service life, so that the water flosser 1 has a longer service life; and when the controller 13 controls the driving device 114 to shut down, the controller 13 controls the prompt device to send a prompt message to prompt the user to add liquid to the liquid storage tank 112. When the detected liquid level is higher than the first preset liquid level and lower than or equal to the second preset liquid level, it indicates that the liquid in the liquid storage tank 112 is about to be exhausted. At this time, the controller 13 controls the driving device 114 to reduce the operating speed to reduce the spherical rotor pump 113. This can reduce the temperature of the spherical rotor pump 113 before reaching the first preset liquid level, thereby reducing the probability of the spherical rotor pump 113 getting stuck. The controller 13 also controls the prompt device to send a prompt message to the user to remind the user that the liquid in the liquid storage tank 112 is about to be exhausted. When the detected liquid level is higher than the second preset liquid level, it indicates that there is more liquid in the liquid storage tank 112. The controller 13 controls the driving device 114 to maintain the current operating state to facilitate cleaning of the user's oral cavity.

[0084] Please refer to Figures 2 and 8. In a specific embodiment, the detection device 12 includes a flow detection device 123, which is configured to detect the flow of the pipeline 115. The flow detection device 123 is used to detect the flow of the pipeline 115. When the detected flow is lower than or equal to the first preset flow, the controller 13 controls the driving device 114 to shut down to prevent the driving device 114 from continuing to drive the spherical rotor pump 113 to operate, thereby reducing the probability of the spherical rotor pump 113 idling and causing the rotor and the housing to get stuck, thereby reducing the probability of the driving device 114 burning out, so that the driving device 114 can have a longer service life, so that the oral irrigator 1 has a longer service life.

[0085] Please refer to Figures 2 and 8. In a specific embodiment, the flow detection device 123 includes a grid photoelectric speed measurement code disk 1231, a flow rate detection turbine 1232 and a corresponding photoelectric sensor 1233. The grid photoelectric speed measurement code disk 1231 is rotatably arranged in the shell 111; the flow rate detection turbine 1232 is rotatably arranged in the pipeline 115 and is transmission-connected to the grid photoelectric speed measurement code disk 1231, and is configured to drive the grid photoelectric speed measurement code disk 1231 to rotate; the corresponding photoelectric sensor 1233 is arranged in the shell 111, connected to the controller 13, and corresponding to the grid photoelectric speed measurement code disk 1231; wherein, the rotation speed of the grid photoelectric speed measurement code disk 1231 obtained by the controller 13 via the corresponding photoelectric sensor 1233 corresponds to the magnitude of the detected flow rate.

[0086] When the spherical rotor pump 113 drives the liquid in the liquid storage tank 112 to move in the pipeline 115, the liquid can drive the flow rate detection turbine 1232 to rotate at a faster speed. When the spherical rotor pump 113 drives the air in the liquid storage tank 112 to move in the pipeline 115, the gas can drive the flow rate detection turbine 1232 to rotate at a slower speed. The rotation of the flow rate detection turbine 1232 can drive the grid photoelectric speed code disk 1231 to rotate, thereby causing the grid photoelectric speed code disk 1231 to block the light path of the opposing photoelectric sensor 1233, so that the opposing photoelectric sensor 1233 can obtain the rotation speed of the grid photoelectric speed code disk 1231 according to the blocking frequency; when the rotation speed of the grid photoelectric speed code disk 1231 is greater than the first preset speed, it indicates that the detected flow rate is higher than the first preset flow rate, that is, there is more liquid in the liquid storage tank 112, so that the spherical rotor pump 113 can extract the liquid to clean the user's mouth. When the rotation speed of the grid photoelectric speed code disk 1231 is less than or equal to the first preset rotation speed, it indicates that the detected flow rate is lower than or equal to the first preset flow rate, that is, the liquid in the liquid storage tank 112 is exhausted. At this time, the controller 13 controls the driving device 114 to shut down, so that the spherical rotor pump 113 shuts down, thereby cooling the spherical rotor pump 113 to reduce the probability of the spherical rotor pump 113 getting stuck and the probability of the driving device 114 burning out, thereby making the driving device 114 have a longer service life, so that the water flosser 1 has a longer service life; and the controller 13 also controls the prompt device to issue a prompt message to remind the user that liquid needs to be added to the liquid storage tank 112.

[0087] Please refer to Figures 2 and 8. In a specific embodiment, the flow rate detection turbine 1232 is arranged on the liquid outlet pipe 115 of the spherical rotor pump 113, and is located at one end of the liquid outlet pipe 115 close to the spherical rotor pump 113, which can improve the detection accuracy of the flow rate detection turbine 1232 and thus improve the detection accuracy of the flow rate.

[0088] Specifically, the through-beam photoelectric sensor 1233 includes a slot-type photoelectric sensor having a slot. A portion of the grid photoelectric speed measuring code disk 1231 is located in the slot and can block the light path of the slot-type photoelectric sensor.

[0089] Please refer to Figures 2 and 9. In a specific embodiment, the flow detection device 123 also includes a magnetic flow velocity detection turbine 1234 and a Hall sensor 1235. The magnetic flow velocity detection turbine 1234 is rotatably arranged in the pipeline 115; the Hall sensor 1235 is arranged in the shell 111, connected to the controller 13, and corresponding to the magnetic flow velocity detection turbine 1234; wherein, the rotation speed of the magnetic flow velocity detection turbine 1234 obtained by the controller 13 via the Hall sensor 1235 corresponds to the size of the detected flow rate.

[0090] When the rotation speed of the magnetic flow velocity detection turbine 1234 is greater than the first preset rotation speed, it indicates that the detected flow rate is higher than the first preset flow rate, that is, there is more liquid in the liquid storage tank 112, so that the spherical rotor pump 113 can pump out the liquid to clean the user's mouth. When the rotation speed of the magnetic flow velocity detection turbine 1234 is less than or equal to the first preset rotation speed, it indicates that the detected flow rate is lower than or equal to the first preset flow rate, that is, the liquid in the liquid storage tank 112 is exhausted. At this time, the controller 13 controls the drive device 114 to shut down, so as to shut down the spherical rotor pump 113, thereby cooling the spherical rotor pump 113, reducing the probability of the spherical rotor pump 113 getting stuck, and reducing the probability of the drive device 114 burning out, thereby extending the service life of the drive device 114 and extending the service life of the oral irrigator 1. The controller 13 also controls the prompt device to issue a prompt message to remind the user that liquid needs to be refilled into the liquid storage tank 112.

[0091] Please refer to Figures 2 and 9. In a specific embodiment, the magnetic flow velocity detection turbine 1234 is arranged on the liquid outlet pipe 115 of the spherical rotor pump 113, and is located at one end of the liquid outlet pipe 115 close to the spherical rotor pump 113, which can improve the detection accuracy of the flow velocity detection turbine 1232 and thus improve the detection accuracy of the detection flow rate.

[0092] Please refer to Figures 2 and 10. In a specific embodiment, the flow detection device 123 also includes a pressure sleeve 1236, which is sleeved around the pipeline 115 and connected to the controller 13; wherein the pressure of the pressure sleeve 1236 obtained by the controller 13 corresponds to the size of the detection flow.

[0093] When the spherical rotor pump 113 pumps the liquid from the liquid storage tank 112 through the pipe 115, the liquid in the pipe 115 presses against the wall of the pipe 115, allowing the pressure value to be detected by the pressure sleeve 1236. The more liquid in the pipe 115, the greater the pressure in the pressure sleeve 1236; the less liquid in the pipe 115, the lower the pressure in the pressure sleeve 1236. When the pressure in the pressure sleeve 1236 is greater than the first preset pressure, it indicates that the detected flow rate is higher than the first preset flow rate, that is, there is more liquid in the liquid storage tank 112. The controller 13 controls the drive device 114 to maintain the current operating state, so that the spherical rotor pump 113 can pump the liquid from the liquid storage tank 112 to clean the user's mouth. When the pressure of the pressure sleeve 1236 is less than or equal to the first preset pressure, it indicates that the detected flow rate is lower than or equal to the first preset flow rate, that is, the liquid in the liquid storage tank 112 is exhausted. At this time, the controller 13 controls the driving device 114 to shut down, so that the spherical rotor pump 113 can be shut down, thereby cooling the spherical rotor pump 113 to reduce the probability of the spherical rotor pump 113 getting stuck and the probability of the driving device 114 burning out, thereby making the driving device 114 have a longer service life, so that the water flosser 1 has a longer service life; and the controller 13 also controls the prompt device to issue a prompt message to remind the user that liquid needs to be added to the liquid storage tank 112.

[0094] Please refer to Figures 2 and 10. In a specific embodiment, the pressure sleeve 1236 is arranged on the liquid outlet pipe 115 of the spherical rotor pump 113 and is located at one end of the liquid outlet pipe 115 close to the spherical rotor pump 113, which can improve the detection accuracy of the flow rate detection turbine 1232 and thus improve the detection accuracy of the flow rate.

[0095] 2 and 11 , in a specific embodiment, the detection device 12 includes a current detection component 124 , which is configured to detect the current of the driving device 114 ; wherein the controller 13 is configured to obtain the detection current of the current detection component 124 .

[0096] The current of the drive device 114 is detected by the current detection component 124. When the drive device 114 drives the spherical rotor pump 113 to idle, the detection current of the current detection component 124 is relatively small. When the drive device 114 drives the spherical rotor pump 113 to pump water, the detection current of the current detection component 124 is relatively large. When the detection current is less than or equal to the first preset current, it indicates that the liquid in the liquid storage tank 112 is exhausted. At this time, the controller 13 controls the drive device 114 to shut down, so that the spherical rotor pump 113 shuts down, thereby cooling the spherical rotor pump 113, reducing the probability of the spherical rotor pump 113 being stuck due to excessive dry-running temperature, and reducing the probability of the drive device 114 burning out. This can extend the service life of the drive device 114, thereby extending the service life of the oral irrigator 1. When the detected current is greater than the first preset current, it indicates that there is more liquid in the liquid storage tank 112. The controller 13 controls the driving device 114 to maintain the current operating state so that the spherical rotor pump 113 can pump out the liquid in the liquid storage tank 112, thereby cleaning the user's mouth.

[0097] Please refer to Figures 2 and 11. In some embodiments, after the detection current is less than or equal to the first preset current and lasts for a third period of time, the controller 13 controls the driving device 114 to shut down, so as to eliminate the situation where the liquid level in the liquid storage tank 112 is lowered due to the user's usage posture, causing the spherical rotor pump 113 to idle, thereby improving the accuracy of the detection results of the detection device 12.

[0098] Please refer to Figures 2 and 11. In a specific embodiment, when the detected current is less than the second preset current and greater than the first preset current, the controller 13 controls the drive device 114 to maintain the current operating state, and the controller 13 obtains the situation that the spherical rotor pump 113 is not running at full load, so that the controller 13 can obtain the state information before the first preset current, thereby improving the judgment accuracy of the controller 13.

[0099] Please refer to Figures 2 and 11. In a specific embodiment, when the detection current is less than the second preset current and the detection current gradually decreases within the eighth time period, the controller 13 obtains that the spherical rotor pump 113 is not operating at full load and the liquid level in the liquid storage tank 112 is gradually decreasing. At this time, the controller 13 can control the drive device 114 to maintain the current operating state to reduce the probability of misjudgment of the liquid level state due to the user's posture, thereby improving the judgment accuracy of the controller 13. The second preset current is greater than the first preset current. Exemplarily, the eighth time period can be 30 seconds, 1 minute, 1 minute and 30 seconds, or 2 minutes.

[0100] Referring to Figures 2 and 11 , in a specific embodiment, when the detection current is less than the second preset current and the detection current gradually decreases within the ninth time period, the controller 13 controls the drive device 114 to maintain the current operating state for the tenth time period, so that the spherical rotor pump 113 can completely draw the liquid from the liquid storage tank 112, thereby reducing the residual liquid in the liquid storage tank 112. The second preset current is greater than the first preset current. Exemplarily, the ninth and tenth time periods can be 30 seconds, 1 minute, 1 minute 30 seconds, and 2 minutes, respectively.

[0101] Referring to Figures 2 and 11 , in a specific embodiment, the controller 13 is further configured to control the current detection component 124 to not detect current during the eleventh time period after the drive device 114 is started. Because a large current exists and rapidly decreases during the eleventh time period when the drive device 114 transitions from a shutdown state to an operating state, the current of the drive device 114 is not detected during the eleventh time period to improve the accuracy of current detection. For example, the eleventh time period can be 80 milliseconds, 90 milliseconds, 100 milliseconds, or 110 milliseconds.

[0102] Referring to Figures 2 and 11 , in a specific embodiment, after the seventh time period of activation of the drive device 114, if the detection current is less than or equal to the first preset current, it indicates that the spherical rotor pump 113 has not drawn liquid or has drawn very little liquid during the seventh time period after activation. To prevent the spherical rotor pump 113 from overheating and freezing, the controller 13 controls the drive device 114 to shut down. After the twelfth time period of activation of the drive device 114, if the detection current is less than the second preset current and greater than the first preset current, and the detection current gradually increases, it indicates that the spherical rotor pump 113 has drawn liquid. The controller 13 controls the drive device 114 to maintain its current operating state, thereby allowing the liquid in the liquid storage tank 112 to clean the user's mouth. The second preset current is greater than the first preset current. For example, the seventh and twelfth time periods can be 80 milliseconds, 90 milliseconds, 100 milliseconds, and 110 milliseconds, respectively.

[0103] 2 and 11 , in a specific embodiment, when the detected current is less than or equal to the first preset current, the controller 13 controls the prompt device to issue a prompt message to prompt the user to add liquid to the liquid storage tank 112 .

[0104] Please refer to Figures 2 and 11. In a specific embodiment, when the detection current is less than the second preset current and greater than the first preset current, it indicates that there is less liquid in the liquid storage tank 112. Therefore, the controller 13 can control the drive device 114 to maintain the current operating state, so that the spherical rotor pump 113 can pump out the liquid in the liquid storage tank 112, thereby cleaning the user's mouth. When the detection current is greater than or equal to the third preset current, it indicates that the spherical rotor pump 113 is stuck. At this time, the controller 13 controls the drive device 114 to shut down to prevent the drive device 114 from being burned out, so that the drive device 114 has a longer service life, and thus the oral irrigator 1 has a longer service life. The controller 13 is also configured to control the drive device 114 to maintain the current operating state when the detection current is less than the third preset current. Among them, the second preset current is greater than the first preset current, and the third preset current is greater than the second preset current.

[0105] Referring to Figures 2 and 11, in a specific embodiment, when the detection current is greater than or equal to the fourth preset current and less than or equal to the third preset current, it indicates that the risk of the spherical rotor pump 113 getting stuck is high. At this time, the driver can control the drive device 114 to shut down within a sixth time period to shut down the spherical rotor pump 113, thereby cooling the spherical rotor pump 113 and reducing the probability of the spherical rotor pump 113 getting stuck. Alternatively, the controller 13 controls the drive device 114 to reduce the operating speed, and when the detection current drops to less than the fourth preset current, the controller 13 controls the drive device 114 to maintain the current operating state, so that the oral irrigator 1 can clean the user's oral cavity. The fourth preset current is greater than the second preset current and less than the third preset current.

[0106] Please refer to Figures 2 and 11. In a specific embodiment, when the detected current is greater than or equal to the third preset current, it indicates that the spherical rotor pump 113 is stuck. At this time, the controller 13 controls the driving device 114 to shut down to prevent the driving device 114 from being burned out, so that the driving device 114 has a longer service life, and thus the oral irrigator 1 has a longer service life, and controls the prompt device to issue a prompt message to prompt the user that the spherical rotor pump 113 is stuck; and controls the driving device 114 to remain in a shutdown state within a second time period to prevent the spherical rotor pump 113 from being stuck again, thereby reducing the probability of the driving device 114 being burned out.

[0107] Please refer to Figures 2 and 11. In a specific embodiment, after the detection current is greater than or equal to the third preset current and the driving device 114 is controlled to shut down, when a start signal is received within the second time period, in order to ensure that the spherical rotor pump 113 is prevented from getting stuck, the controller 13 controls the driving device 114 to remain in the shutdown state and controls the prompt device to issue a prompt message to prompt the user that the driving device 114 remains in the shutdown state and cannot operate.

[0108] Referring to Figures 2 and 11 , in a specific embodiment, if the detected current is at least less than the first preset current during the thirteenth time period after the drive device 114 is activated, the spherical rotor pump 113 is operating normally, and the controller 13 controls the drive device 114 to maintain the current operating state. If the detected current is greater than or equal to the fourth preset current during the thirteenth time period after the drive device 114 is activated, the spherical rotor pump 113 is stuck, and to prevent the drive device 114 from burning out, the controller 13 controls the drive device 114 to shut down. The fourth preset current is greater than the first preset current. For example, the thirteenth time period can be 10 seconds, 20 seconds, 30 seconds, 40 seconds, or 50 seconds.

[0109] Please refer to Figures 2 and 11. In a specific embodiment, the controller 13 is further configured to control the driving device 114 to reduce the operating speed or control the driving device 114 to shut down in order to protect the driving device 114 when the rising speed of the detected current is greater than a preset rising speed, indicating that there is no water in the liquid storage tank 112 or the liquid level in the liquid storage tank 112 is low. In order to prevent the spherical rotor pump 113 from idling, the controller 13 controls the driving device 114 to reduce the operating speed or controls the driving device 114 to shut down.

[0110] 2 and 11 , in a specific embodiment, the detection current is the average current of the driving device 114 during the fourteenth time period, thereby improving the accuracy of the detection current obtained by the controller 13. For example, the fourteenth time period can be 80 milliseconds, 90 milliseconds, 100 milliseconds, or 110 milliseconds.

[0111] Referring to FIG. 1 , FIG. 2 and FIG. 12 , an embodiment of the present application further provides a method for controlling a water flosser 1 , wherein the method is preferably configured as a water flosser 1 , and includes:

[0112] Step 100 : Acquire a detection value of a factor affecting the stuck rotation of the spherical rotor pump 113 or a detection value corresponding to the stuck rotation of the spherical rotor pump 113 .

[0113] In the embodiment of the present application, the controller 13 uses the detection device 12 to obtain a detection value of a factor affecting the stuck rotation of the spherical rotor pump 113 or a detection value corresponding to the stuck rotation of the spherical rotor pump 113 .

[0114] Step 200 : Control the operation of the driving device 114 according to the detection value of the detection device 12 .

[0115] In an embodiment of the present application, when the detection device 12 detects a detection value of a factor affecting the jamming of the spherical rotor pump 113 or a detection value corresponding to the jamming of the spherical rotor pump 113, the controller 13 controls the driving device 114 to reduce the operating speed or shut down, which can reduce the probability of the spherical rotor pump 113 getting stuck; and when the spherical rotor pump 113 gets stuck abnormally, the controller 13 can control the driving device 114 to shut down to prevent the driving device 114 from burning out, which can make the driving device 114 have a longer service life, and thus the water flosser 1 can have a longer service life.

[0116] Please refer to FIG1, FIG2, FIG12 and FIG13, in a specific embodiment,

[0117] Step 200 includes:
