[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0023] In a preferred embodiment, reference Figure 1 The handheld tooth washer capable of continuously adjusting water pressure of this embodiment comprises a controller 10, a water pump driving circuit 20, a pressure sensor 30, a power supply 40 and a water pump 50. The controller 10 is respectively connected to the pressure sensor 30 and the water pump driving circuit 20. The water pump driving circuit 20 is connected to and drives the water pump 50. The water pump 50 discharges water to form water pressure. The power supply 40 is respectively connected to and supplies power to the controller 10 and the water pump driving circuit 20.

[0024] When using the handheld tooth washer, the user adjusts the output water pressure by pressing the pressure sensor 30. The user can directly apply external pressure to the pressure sensor 30, or indirectly apply external pressure to the pressure sensor 30 through a pressure button (not shown in the figure). The pressure sensor 30 undergoes electrical changes under the action of external pressure and generates an adjustment signal. The adjustment signal changes with the change of the external pressure. Since the external pressure can change continuously, the adjustment signal can change continuously. The pressure sensor 30 transmits the adjustment signal to the controller 10. The controller 10 generates a water pump drive signal according to the adjustment signal. The water pump drive signal changes with the change of the adjustment signal. Since the adjustment signal is a continuously changing signal, the water pump drive signal is also a continuously changing signal. The controller 10 sends the continuously changing water pump drive signal to the water pump drive circuit 20. The water pump drive circuit 20 executes the water pump drive signal to drive the water pump 50 to operate, and the water pump 50 discharges water to form water pressure. Since the water pump drive signal is a continuously changing signal, the water pump 50 can generate a continuously changing water pressure, thereby realizing the continuous adjustment of the water pressure of the handheld tooth washer.

[0025] The adjustment signal generated by the pressure sensor in this embodiment is a continuous value, which in turn makes the water pump drive signal a continuous value, thereby achieving continuous adjustment of the output water pressure of the handheld toothbrush and meeting the user's personalized needs for water pressure.

[0026] In some embodiments of the handheld tooth washer that can continuously adjust the water pressure, the adjustment signal is a voltage signal, that is, the pressure sensor 30 generates a voltage change under the action of external pressure, and the voltage signal changes with the change of the external pressure. Since the external pressure can change continuously, the voltage signal can change continuously. The pressure sensor 30 transmits the voltage signal to the controller 10, and the controller 10 generates a water pump drive signal according to the voltage signal. The water pump drive signal changes with the change of the voltage signal. Since the voltage signal is a continuously changing signal, the water pump drive signal is also a continuously changing signal. The controller 10 sends the continuously changeable water pump drive signal to the water pump drive circuit 20, and the water pump drive circuit 20 executes the water pump drive signal to drive the water pump 50 to operate, and the water pump 50 discharges water to form water pressure. Since the water pump drive signal is a continuously changing signal, the water pump 50 can generate a continuously changing water pressure, thereby realizing the continuous adjustment of the water pressure of the handheld tooth washer. Alternatively, the controller 10 or the memory 70 in communication with the controller 10 stores a correspondence between voltage and drive signal, the correspondence between voltage and drive signal including the correspondence between voltage signal and water pump drive signal, and the controller 10 searches for the water pump drive signal corresponding to the voltage signal according to the correspondence between voltage and drive signal. The voltage signal generated by the pressure sensor in this embodiment is a continuous value, which in turn makes the water pump drive signal a continuous value, thereby realizing continuous adjustment of the output water pressure of the handheld tooth washer and meeting the user's personalized needs for water pressure.

[0027] In some embodiments of the handheld tooth washer that can continuously adjust the water pressure, the adjustment signal is a current signal, that is, the pressure sensor 30 generates a change in current under the action of external pressure, and the current signal changes with the change of the external pressure. Since the external pressure can change continuously, the current signal can change continuously. The pressure sensor 30 transmits the current signal to the controller 10, and the controller 10 generates a water pump drive signal according to the current signal. The water pump drive signal changes with the change of the current signal. Since the current signal is a continuously changing signal, the water pump drive signal is also a continuously changing signal. The controller 10 sends the continuously changeable water pump drive signal to the water pump drive circuit 20, and the water pump drive circuit 20 executes the water pump drive signal to drive the water pump 50 to operate, and the water pump 50 discharges water to form water pressure. Since the water pump drive signal is a continuously changing signal, the water pump 50 can generate a continuously changing water pressure, thereby realizing the continuous adjustment of the water pressure of the handheld tooth washer. Alternatively, the controller 10 or the memory 70 in communication with the controller 10 stores a correspondence between the current and the drive signal, the correspondence between the current and the drive signal including the correspondence between the current signal and the water pump drive signal, and the controller 10 searches for the water pump drive signal corresponding to the current signal according to the correspondence between the current and the drive signal. The current signal generated by the pressure sensor in this embodiment is a continuous value, which in turn makes the water pump drive signal a continuous value, thereby realizing continuous adjustment of the output water pressure of the handheld tooth washer and meeting the user's personalized needs for water pressure.

[0028] In some embodiments of the handheld dental washer with continuously adjustable water pressure, the external pressure is positively correlated with the water pressure generated by the water pump 50, that is, the greater the external pressure applied by the user, the greater the water pressure of the handheld dental washer; the smaller the external pressure applied by the user, the smaller the water pressure of the handheld dental washer. Alternatively, the external pressure is directly proportional to the water pressure generated by the water pump 50.

[0029] In some embodiments of the handheld dental washer capable of continuously adjusting water pressure, reference is made to Figure 2 The handheld tooth washer of this embodiment also includes a storage button 60 and a memory 70 connected to the controller 10, wherein the storage button 60 is used to generate a storage instruction. When the user wants to store the current water pump drive signal, the storage button 60 is pressed, and the storage button 60 generates a storage instruction; as an option, the storage button 60 can be a virtual button. The storage button 60 sends the storage instruction to the controller 10, and the controller 10 obtains and saves the current water pump drive signal to the memory 70 after receiving the storage instruction generated by the storage button 60. As an option, in order to facilitate the user to view the stored water pump drive signal, a storage name is set for each water pump drive signal when storing, for example, a digital number, storage time and water pressure size are used as the storage name. This embodiment allows the user to store certain water pump drive signals. After the user adjusts to a more comfortable water pressure during use, the water pump drive signal under the water pressure can be stored. The user can directly use the stored water pump drive signal later, and no longer needs to repeatedly adjust the pressure sensor 30 to quickly find the water pressure that suits him, so as to realize the personalized customization of the water pressure.

[0030] In some embodiments of the handheld dental washer capable of continuously adjusting water pressure, reference is made to Figure 3 The handheld tooth washer of this embodiment also includes a selection button 80 connected to the controller 10 for generating a selection instruction. When the user wants to select a stored water pump drive signal, the user presses the selection button 80, and the selection button 80 sends the generated selection instruction to the controller 10. After receiving the selection instruction, the controller 10 reads the water pump drive signal corresponding to the selection instruction in the memory 70, and the water pump drive circuit 20 executes the water pump drive signal to drive the water pump 50 to operate and generate the water pressure required by the user. In this embodiment, the user can directly use the stored water pump drive signal to quickly find the water pressure that suits him / her, and no longer needs to repeatedly adjust the pressure sensor 30, so as to achieve rapid positioning of the water pressure.

[0031] In some embodiments, the handheld toothbrush with continuously adjustable water pressure further includes a power button and a power off button connected to the controller 10, wherein the power button is used to generate a power on command, and the power off button is used to generate a power off command; alternatively, the power on button and the power off button may be the same button. After receiving the power off command, the controller 10 stores the water pump drive signal used before the power off to the memory 70, and after receiving the power on command, the controller 10 reads and executes the water pump drive signal stored before the power off. This embodiment automatically stores the water pump drive signal used by the user when the power is turned off, and automatically runs the water pump drive signal when the power is turned on next time, so that the water pressure generated before and after the power off is the same, thereby improving the user experience.

[0032] In some embodiments of the handheld dental washer capable of continuously adjusting water pressure, reference is made to Figure 4 The handheld tooth washer of this embodiment further includes a display screen 90 connected to the controller 10. The controller 10 or a memory 70 connected to the controller 10 in communication stores a corresponding relationship between a drive signal and water pressure. The corresponding relationship between the drive signal and water pressure includes a corresponding relationship between a water pump drive signal and an outlet water pressure. The controller 10 searches for the water pressure corresponding to the water pump drive signal according to the corresponding relationship between the drive signal and the water pressure. The display screen 90 is used to display the water pressure corresponding to the water pump drive signal in real time, so that the user can understand the current water pressure in real time. Of course, the display screen 90 can also be used to display other user interaction information or prompt information of the handheld tooth washer. Alternatively, the water pressure can be a relative water pressure value, for example, a relative water pressure value range of 0 to 100 is set.

[0033] In some embodiments of the handheld dental cleaner capable of continuously adjusting water pressure, the power supply 40 is a power battery, which is a rechargeable battery.

[0034] In some embodiments, the handheld dental washer with continuously adjustable water pressure further comprises a water storage container connected to the water pump 50 through a pipeline and used for storing water.
