Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oral irrigator, in particular to an oral irrigator and a water outlet device. BACKGROUND

[0002] Oral irrigator is a kind of household oral care product, which can clean food residues accumulated in teeth and interdental spaces by outputting high-pressure pulse water flow, so as to achieve effective cleaning of teeth, improvement of gingivitis, reduction of gingival bleeding and fresh breath. With the increasing attention to personal oral health, oral irrigator is also becoming more and more popular. At present, the oral irrigator of the prior art generally has a water storage tank, which is used to store a certain amount of water in advance. When the oral irrigator is needed, the core part of the oral irrigator draws water from the water storage tank. After the oral irrigator is used, if there is residual water in the water storage tank, the residual water needs to be discharged to prevent the residual water from breeding bacteria and polluting the water storage environment of the water storage tank. At present, the way to discharge the water in the water storage tank of the oral irrigator is generally to provide a cover on the water storage tank, which can be opened and closed. When the residual water needs to be discharged, the cover is opened, and then the water in the water storage tank is poured out. However, this way of discharging the residual water has the following disadvantages: it needs to be operated manually, it is not convenient, and the cover is repeatedly opened and closed, which is easy to cause water leakage. SUMMARY

[0005] Further, the base is provided with a water passing channel, and the water passing hole is communicated with the water passing channel when the water passing hole is opened; further comprising a drainage mechanism, the water inlet end of the drainage mechanism being communicated with the water passing channel; the drainage mechanism is connected with a circuit board.

[0006] Further, the water storage tank and / or the base is provided with a liquid level sensor for detecting the water level and sending the detected water level signal to the circuit board, and the circuit board controls the drainage mechanism to start draining when the liquid level sensor continuously detects the set water level signal for more than a preset value.

[0007] Further, the liquid level sensor is arranged on the water storage tank, and a signal output end of the liquid level sensor is exposed. A contact terminal is arranged on the base and electrically connected with the circuit board. When the oral irrigator is placed on the base, the signal output end of the liquid level sensor contacts the contact terminal to transmit a signal to the circuit board through the contact terminal. The water pumping mechanism is a water pump or a drain electromagnetic valve, and the circuit board is arranged in the base.

[0008] Further, the water inlet mechanism is arranged to control whether the water storage tank is filled with water when the oral irrigator is placed on the base. A water inlet end of the water inlet mechanism is connected with a water source, and a water outlet end of the water inlet mechanism is communicated with the water passing channel.

[0009] Further, the water passing channel is communicated with the water inlet end of the drain mechanism and the water outlet end of the water inlet mechanism through a three-way water path. The water inlet mechanism is a water inlet electromagnetic valve.

[0010] Further, the base has a pressable part, and the circuit board is connected with a micro switch. When the pressable part is pressed, the micro switch is triggered to control the water inlet mechanism to start water inlet.

[0011] Further, the base comprises a face cover and a bottom shell. The face cover is pressably connected with the bottom shell and constitutes the pressable part. The face cover is used to support the oral irrigator and can be pressed downward by the oral irrigator. The face cover is connected with a reset elastic member to provide upward reset of the face cover.

[0012] Further, the water storage tank is provided with a liquid level sensor. When the liquid level sensor detects that the water storage tank is filled with water to a set maximum water level, the circuit board controls the water inlet mechanism to stop water inlet.

[0013] Further, a first magnet is arranged at the bottom of the water storage tank, and a Hall sensor is arranged on the circuit board. When the oral irrigator is lifted during water inlet of the water storage tank, the Hall sensor cannot sense the first magnet and sends a signal to the circuit board to control the water inlet mechanism to stop.

[0014] Further, when the oral irrigator is placed on the base, the oral irrigator and the base are matched with positioning structures to provide positioning for the oral irrigator. The positioning structures comprise a first magnet arranged at the bottom of the water storage tank and a second magnet arranged on the base.

[0015] Further, a wireless charging module is arranged on the base and can charge the core part of the oral irrigator and / or the circuit board when the oral irrigator is placed on the base.

[0016] The application further provides a water outlet device, comprising a faucet, and further comprising a water jet device of the application as described above, wherein water in the water storage tank is from mixed water output by a mixing valve core arranged in the faucet.

[0017] Compared with the prior art, the application has the following beneficial effects:

[0018] 1. The water storage tank is provided with a water passing hole, and a water stopping part is arranged at the water passing hole. The water stopping part opens the water passing hole when the water jet device is placed on the base, and closes the water passing hole when the water jet device is lifted. When the water passing hole is opened, residual water in the water storage tank can be discharged, so that the application has the function of automatically discharging residual water in the water storage tank, thereby avoiding manual disassembly of the cover by the user, making the use of the user more convenient, and greatly reducing the problem of water leakage of the water storage tank.

[0019] 2. The application uses a liquid level sensor to detect the cooperation circuit board to control the drainage timing of the drainage mechanism, so that the application is more intelligent, further improves the convenience of use of the user, and also ensures that residual water in the water storage tank can be discharged in time to reduce bacterial growth. In particular, the liquid level sensor realizes signal transmission by contacting the contact terminal arranged on the base, without the need of connecting a lead, so that the overall structure is more simple.

[0020] 3. The drainage mechanism preferably uses a water pump, which can solve the problem that residual water cannot be discharged due to negative pressure in the water storage tank.

[0021] 4. The application further comprises a water inlet mechanism for controlling whether the water storage tank is filled with water when the water jet device is placed on the base, so that the application can control the automatic water filling of the water storage tank, thereby avoiding manual water filling by the user, making the use of the user more convenient. In particular, the application triggers a micro switch to control the water inlet mechanism to open water inlet by pressing the face cover of the base of the water jet device, so that the application controls the water inlet mechanism to start water inlet in a novel way, and can reduce the problem of accidental water inlet caused by accidental triggering of the micro switch.

[0022] 5. The application uses a liquid level sensor to detect that the water storage tank is filled with water to reach a set maximum water level, and controls the water inlet mechanism to close water inlet, so that the application can realize automatic water closing, and can ensure that the water inlet amount of the water storage tank is constant each time, meeting the water jet requirement.

[0023] 6. The water storage tank is provided with a first magnet, and a Hall sensor is arranged on the circuit board. When the water jet device is lifted during the water filling process of the water storage tank, the Hall sensor cannot sense the first magnet, and sends a signal to the circuit board, so that the circuit board controls the water inlet mechanism to close, thereby avoiding the situation that water is sprayed outward when the water jet device is accidentally lifted.

[0024] 7、The positioning structure is arranged, so that the oral irrigator is placed on the base in a more stable and firm state.

[0034] Please refer to Figures 1-4 As shown in the figure, the oral irrigator of the present application comprises a handheld oral irrigator 1 and a base 2. The oral irrigator 1 comprises a core part 12, a water storage tank 11 and a spray rod 13. The spray rod 13 is arranged on the core part 12. The core part 12 is connected to the water storage tank 11 and can draw water from the water storage tank 11 to make water sprayed from the spray rod 13. The oral irrigator 1 is arranged on the base 2 in a removable manner. The bottom of the water storage tank 11 is provided with a water passing hole 111. A water stopping part 15 is arranged at the water passing hole 111. When the oral irrigator 1 is placed on the base 2, the water stopping part 15 is abutted by the part on the base 2 corresponding to the water stopping part 15 to open the water passing hole 111. When the oral irrigator 1 is lifted up, the water stopping part 15 is automatically reset and closes the water passing hole 111. When the water passing hole 111 is opened, the residual water in the water storage tank 11 can be discharged. Specifically, the base 2 is provided with a water passing channel 211. When the oral irrigator 1 is placed on the base 2, the opened water passing hole 111 is communicated with the water passing channel 211.

[0035] As a preferred structure, the present application further comprises a water discharging mechanism. The water inlet of the water discharging mechanism is communicated with the water passing channel 211 of the base 2. The water discharging mechanism is connected with a circuit board 4 which is arranged in the base 2. The water discharging mechanism is specifically a water pump 3 which can solve the problem that the residual water in the water storage tank 11 cannot be discharged due to negative pressure. In other embodiments, the water discharging mechanism is a water discharging electromagnetic valve and the like. In order to solve the problem that the residual water in the water storage tank 11 is difficult to discharge due to negative pressure, an openable and closable air port can also be arranged on the water storage tank. When the water storage tank needs to discharge the residual water, the air port is opened to destroy the negative pressure so that the residual water in the water storage tank can be smoothly discharged.

[0036] In the embodiment, the water tank 11 is provided with a liquid level sensor 14 for detecting the water level in the water tank 11 and sending the detected water level signal to the circuit board 4 when the oral irrigator 1 is placed on the base 2. The circuit board 4 controls the drainage mechanism (i.e. the water pump 3) to start draining when the liquid level sensor 14 continuously detects the set water level signal for more than a preset time, and controls the drainage mechanism (i.e. the water pump 3) to stop draining when the liquid level sensor 14 does not detect the water level signal. The set water level signal is preferably a preset low water level signal, but is not limited thereto. In other embodiments, the set water level signal can include a preset low water level signal and a preset high water level signal, so that the oral irrigator can not only drain the residual water in the water tank 11 after use, but also drain the high water level water in the water tank 11 that is not drained in time, thereby avoiding the growth of bacteria. In other embodiments, the application uses a control switch instead of the liquid level sensor 14, which is operated by the user to control whether the drainage mechanism drains or not. In other embodiments, the liquid level sensor is provided on the base, or in addition to the liquid level sensor provided on the water tank, a liquid level sensor is also provided on the base for detecting the water level in the water passage of the base. When the water passage hole at the bottom of the water tank is opened, the residual water in the water tank can automatically drain into the water passage of the base without negative pressure in the water tank. At this time, the liquid level sensor sends the detected water level signal in the water passage to the circuit board, so that the circuit board controls the drainage mechanism to start draining, thereby avoiding the water in the water passage from staying for too long and growing bacteria.

[0037] In the embodiment, the base 2 is provided with a contact terminal 23 electrically connected to the circuit board 4, and the signal output end of the liquid level sensor 14 is exposed. When the oral irrigator 1 is placed on the base 2, the signal output end of the liquid level sensor 14 contacts the contact terminal 23 to transmit the signal to the circuit board 4 through the contact terminal 23, thereby avoiding additional connection leads and making the overall structure more compact. Specifically, the signal output end of the liquid level sensor 14 is visible at the bottom surface of the water tank 11, but is not limited thereto. In other embodiments, the signal output end of the liquid level sensor 14 is visible on the outer side surface of the water tank 11. The number of liquid level sensors 14 is two, but is not limited thereto. The number of contact terminals 23 is one. The oral irrigator 1 has multiple placement angles to make it more convenient for users to use, and only one liquid level sensor 14 needs to be in contact with the contact terminal 23 when placed.

[0038] The application also comprises a water inlet mechanism for controlling whether the water tank 11 is filled with water or not when the oral irrigator 1 is placed on the base 2. The water inlet end of the water inlet mechanism is connected to a water source, and the water outlet end of the water inlet mechanism is connected to the water passage 211 of the base 2. Specifically, the water passage 211 of the base 2 is connected to the water inlet end of the water pump 3 and the water outlet end of the water inlet mechanism through the three-way water path 6. Therefore, the water passage hole 111 at the bottom of the water tank 1 can be used for both water inlet and water outlet, so that the water tank 1 is free from multiple water passage holes, thereby reducing the space requirement at the bottom of the water tank and meeting the miniaturization design requirement of the oral irrigator. The water inlet mechanism is specifically a water inlet electromagnetic valve 5, but is not limited thereto, and is electrically connected to the circuit board 4.

[0039] As a preferred structure, the base 2 has a pressable part, and the circuit board 4 is connected with a micro switch 41. When the pressable part is pressed, the micro switch 41 is triggered, so that the circuit board 4 controls the water inlet mechanism (i.e. the water inlet electromagnetic valve 5) to open the water inlet. Specifically, in the embodiment, the base 2 comprises a face cover 21 and a bottom shell 22. The face cover 21 is pressably connected to the bottom shell 21 and constitutes the pressable part. The face cover 21 is used for supporting the oral irrigator and is provided with the water passage 211 and the contact terminal 23. The face cover 21 can be pressed downward by the oral irrigator 1. The face cover 21 is connected with a reset elastic member 24, which is specifically a spring, for providing upward reset of the face cover 21. The bottom shell 22 is assembled by two parts, but is not limited thereto. In other embodiments, the pressable part on the base is a button structure mounted on the base.

[0040] In the embodiment, the circuit board 4 controls the water inlet mechanism (i.e. the water inlet electromagnetic valve 5) to close the water inlet when the liquid level sensor 14 detects that the water in the water tank 11 reaches the set maximum water level.

[0041] Further, the first magnet 16 is mounted at the bottom of the water tank 11, and a Hall sensor (not shown in the figure) is mounted on the circuit board 4. When the oral irrigator 1 is placed on the base 2, the Hall sensor senses the first magnet 16 and sends a signal allowing the water inlet mechanism (i.e. the water inlet electromagnetic valve 5) to open to the circuit board 4. When the oral irrigator 1 is lifted during the water filling process of the water tank 11, the Hall sensor cannot sense the first magnet 16 and sends a signal to the circuit board 4, so that the circuit board 4 controls the water inlet mechanism (i.e. the water inlet electromagnetic valve 5) to close. In this way, the situation that water is sprayed outward when the oral irrigator 1 is accidentally lifted can be avoided.

[0042] In the embodiment, when the oral irrigator 1 is placed on the base 2, the two are matched with positioning structures to provide positioning for the oral irrigator 1. The positioning structures specifically include a first magnet 16 arranged at the bottom of the water storage tank 11 and a second magnet 25 arranged at the base 2, and the first magnet 16 and the second magnet 25 are magnetically attracted when the oral irrigator is placed on the base 2. The first magnet 16 matched with the second magnet 25 is the same as the first magnet 16 matched with the Hall sensor, but is not limited thereto.

[0043] The application also includes a wireless charging module 26 arranged at the base 2 and capable of charging the core part 12 and / or the circuit board 4 of the oral irrigator 1 when the oral irrigator 1 is placed on the base 2.

[0044] The oral irrigator device of the application has the following working principle:

[0045] When the oral irrigator 1 is placed on the base 2, when water needs to be filled into the water storage tank 11, the oral irrigator 1 is pressed downward to press the face cover 21 of the base 2, so that the micro switch 41 below the face cover 21 is triggered, the circuit board 4 controls the water inlet electromagnetic valve 5 to open, water is output from the water outlet end of the water inlet electromagnetic valve 5, and flows into the water storage tank 11 through the water passage 211 of the face cover 21 and the water hole 111 of the water storage tank 11. During the water filling process of the water storage tank 11, if the oral irrigator 1 is accidentally lifted, the Hall sensor on the circuit board 4 cannot sense the first magnet 16 on the water storage tank 11, and sends a signal to the circuit board 4, so that the circuit board 4 controls the water inlet electromagnetic valve 5 to close. When the liquid level sensor 14 detects that the water level in the water storage tank 11 reaches the preset highest water level, the circuit board 4 controls the water inlet electromagnetic valve 5 to close, thereby completing the automatic water filling process of the water storage tank 11.

[0046] When the oral irrigator 1 is used up and placed back on the base 2, if the liquid level sensor 14 detects that the water level in the water storage tank 11 is at the preset low water level and the duration exceeds the preset value, it means that there is residual water in the water storage tank 11, and then the circuit board 4 starts the water pump 3 to pump out the residual water in the water storage tank 11 until the residual water in the water storage tank 11 is exhausted.

[0047] The oral irrigator device of the application not only can automatically fill water, but also can automatically drain the residual water in the water storage tank 11, so that the user can use it very conveniently, and can ensure that the water amount of the water storage tank 11 is constant every time, and reduce the problems of bacterial growth and water leakage.

[0048] Please refer to Figures 1-5As shown, the water outlet device of the present application comprises a faucet 7 and the above-mentioned oral irrigator device, the faucet 7 and the base 2 are arranged on the same table top 40, and the water in the water storage tank 11 is mixed water output by a mixing valve core 71 arranged on the faucet 7, that is, the water inlet end of the above-mentioned water inlet electromagnetic valve 5 is communicated with the mixed water outlet end of the mixing valve core 71. The mixing valve core 71 is specifically a thermostatic valve core, so that the thermostatic water suitable for oral irrigation can be obtained every time the water storage tank 11 is filled.

[0049] In the present embodiment, the water outlet device of the present application further comprises a water outlet electromagnetic valve 8, the water inlet end of the water outlet electromagnetic valve 8 is communicated with the mixed water outlet end of the mixing valve core 71, and the water outlet end of the water outlet electromagnetic valve 8 is connected to the water outlet nozzle of the faucet 7 through a water outlet pipe to control whether the faucet 7 outputs water or not. A push button switch 73 is arranged at the water outlet nozzle of the faucet 7, and the push button switch 73 and the water outlet electromagnetic valve 8 are electrically connected to another circuit board 9, so that when the push button switch 73 is pressed, a signal can be sent to the another circuit board 9, and the another circuit board 4 controls whether the water outlet electromagnetic valve 8 is opened or not. The push button switch 73 can be replaced by a sensor, such as an infrared sensor. The above-mentioned water pump 3, water inlet electromagnetic valve 5 and water outlet electromagnetic valve 8 are arranged in the same support 30, and the support 30 is located below the table top 40.

[0050] In the present embodiment, the base 72 of the faucet 7 is provided with a lamp strip 10 and a light guide plate 20, and the light emitted by the lamp strip 10 is emitted through the light guide plate 20, so that the light is softer. The above-mentioned lamp strip 10 can be electrically connected to the another circuit board 9 to be controlled to be turned on and off by the another circuit board 9. The base 72 of the faucet 7 is arranged together with the base 2 of the oral irrigator device.
