Description

Technical Field

[0001] The utility model relates to the technical field of water flossers, in particular to a water flosser device with automatic water injection function and a water outlet device. Background Art

[0002] An oral irrigator is a home oral care product that uses a high-pressure, pulsed stream of water to remove food particles trapped between teeth and between them, effectively cleaning teeth, improving gingivitis, reducing gum bleeding, and freshening breath. As people prioritize personal oral health, oral irrigators are becoming increasingly popular. Currently, there are two main types of oral irrigators: handheld and tabletop. Handheld irrigators contain a built-in water tank that stores a certain amount of water. During irrigating, the irrigator's mechanism draws water from this tank. Therefore, before irrigating, the water tank must be filled with water. Currently, handheld irrigators typically use a manual water filling method. Specifically, the water tank is opened and the entire device is placed under a faucet to collect water. However, this method has several drawbacks: it requires manual operation, is inconvenient, and is long. Due to the limited space under the faucet, the irrigator must be tilted when placed under the faucet, making it difficult to fully fill the water tank. Utility Model Content

[0003] The utility model aims to solve the technical problems existing in the prior art and provides a tooth flushing device and a water outlet device with an automatic water filling function, which can automatically fill a water tank with water instead of manually.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a tooth flushing device with automatic water filling function, including a handheld tooth flusher and a base, the tooth flusher having a water tank, and the tooth flusher being detachably arranged on the base; also including a water inlet mechanism, which is connected to a circuit board; a water hole is provided at the bottom of the water tank, and a water stop is installed at the water hole, which opens the water hole when the tooth flusher is placed on the base, and closes the water hole when the tooth flusher is lifted; when the water hole is opened, it is connected to the water inlet end of the water inlet mechanism, so that water is filled into the water tank when the water inlet mechanism is opened.

[0005] Furthermore, the water tank is provided with a liquid level sensor for detecting the water level in the water tank and sending the detected water level signal to the circuit board; the circuit board controls the water inlet mechanism to close the water inlet when the liquid level sensor detects that the water inlet of the water tank reaches the set maximum water level.

[0006] Furthermore, a contact terminal is provided on the base, which is electrically connected to the circuit board, and the signal output end of the liquid level sensor is exposed. When the water flosser is placed on the base, the signal output end of the liquid level sensor contacts the contact terminal to transmit the signal to the circuit board through the contact terminal; the circuit board is installed in the base.

[0007] Furthermore, the base has a pressable portion, and the circuit board is connected to a micro switch. When the pressable portion is pressed, the micro switch is triggered, so that the circuit board controls the water inlet mechanism to start water inlet.

[0008] Furthermore, the base includes a face cover and a bottom shell, the face cover can be press-connected to the bottom shell and constitutes the press-able part, and the face cover is used to support the water flosser and can be pressed downward by the water flosser; the face cover is connected to a reset elastic member to provide the face cover with upward reset.

[0009] Furthermore, a first magnet is installed at the bottom of the water tank and a Hall sensor is installed on the circuit board. When the water flosser is lifted during the water filling process of the water 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.

[0010] Furthermore, the base is provided with a water passage, and when the water flosser is placed on the base, the water hole is connected to the water passage; the water passage is connected to the water outlet end of the water inlet mechanism.

[0011] Furthermore, the water inlet mechanism is a water inlet solenoid valve.

[0012] Furthermore, when the water flosser is placed on the base, the two are combined with a positioning structure to provide positioning for the water flosser. The positioning structure includes a first magnet arranged at the bottom of the water tank and a second magnet arranged on the base. When the water flosser is placed on the base, the first magnet and the second magnet are magnetically attracted to each other.

[0013] Furthermore, it also includes a wireless charging module, which is arranged on the base and can charge the core part of the water flosser and / or the circuit board when the water flosser is placed on the base.

[0014] The present invention further provides a water outlet device, comprising a faucet and the tooth flushing device as described above in the present invention, wherein the water in the water storage tank comes from mixed water output by a water mixing valve core provided on the faucet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Since the present invention also includes a water inlet mechanism, a water hole is provided at the bottom of the water tank, and a water stop is installed at the water hole. The water stop opens the water hole when the water irrigator is placed on the base, and closes the water hole when the water irrigator is lifted. When the water hole is opened, it is connected to the water inlet end of the water inlet mechanism, so that water is injected into the water tank when the water inlet mechanism is opened. This makes the present invention have an automatic water filling function, thereby eliminating the need for users to manually fill water, making it more convenient for users to use, and solving the problem of difficulty in filling the water tank with water.

[0017] 2. This utility model uses a liquid level sensor to detect the water level signal in the water tank. When the liquid level sensor detects that the water in the water tank has reached a set maximum water level, the circuit board controls the water inlet mechanism to shut off the water. This allows the utility model to automatically shut off the water and ensure a constant amount of water in the water tank each time, meeting the needs of flushing teeth. In particular, the liquid level sensor transmits signals through contact with contact terminals on the base, eliminating the need for connecting wires and simplifying the overall structure.

[0018] 3. The utility model triggers the micro switch to control the water inlet mechanism to start water inlet by pressing the surface cover of the base of the water flosser, which makes the method of controlling the water inlet mechanism to start water inlet of the utility model relatively novel and can reduce the problem of accidental water inlet caused by accidental triggering of the micro switch.

[0019] 4. A first magnet is installed at the bottom of the water tank, and a Hall sensor is installed on the circuit board. When the water flosser is lifted during the water filling process of the water 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 preventing water from spraying out when the water flosser is accidentally lifted.

[0020] 5. The positioning structure makes the water flosser more stable and secure when placed on the base. In particular, the positioning structure includes the first magnet and the second magnet, which enables the positioning structure to achieve automatic positioning, making it more convenient for users to use.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments; however, the present invention is not limited to the embodiments as it is a tooth flushing device and a water outlet device with an automatic water injection function.

For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See Figures 1-4As shown, a tooth irrigator device of the present invention includes a handheld tooth irrigator 1 and a base 2. The tooth irrigator 1 includes a core part 12, a water 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 tank 11 and can pump water from the water tank 11 to spray water out from the spray rod 13. The tooth irrigator 1 is arranged on the base 2 in a removable manner. The present invention also includes a water inlet mechanism, which is electrically connected to a circuit board 4. A water hole 111 is provided at the bottom of the water tank 11. A water stop 15 is installed at the water hole 111. When the tooth irrigator 1 is placed on the base 2, the water stop 15 is pressed by the part of the base 2 corresponding to the water stop 15 to open the water hole 111. When the tooth irrigator 1 is lifted, the water stop 15 automatically resets and closes the water hole 111. When open, the water hole 111 connects to the water inlet end of the water inlet mechanism, allowing water to be injected into the water tank 11. Specifically, the base 2 is provided with a water passage 211. When the oral irrigator 1 is placed on the base 2, the open water hole 111 connects to the water passage 211, and the water inlet end of the water inlet mechanism connects to the water passage 211. The water inlet mechanism is specifically, but not limited to, a water inlet solenoid valve 5. In other embodiments, the water inlet mechanism can be a water pump, etc. A circuit board 4 is mounted in the base 2.

[0031] In this embodiment, a liquid level sensor 14 is provided in the water tank 11 to detect the water level therein. When the oral irrigator 1 is placed on the base 2, the detected water level signal is transmitted to the circuit board 4. When the liquid level sensor 14 detects that the water in the water tank 11 has reached a set maximum water level, the circuit board 4 controls the water inlet mechanism (i.e., the water inlet solenoid valve 5) to shut off the water inlet. In other embodiments, the present invention utilizes a control switch in place of the liquid level sensor 14. This control switch is operated by the user to control whether the water inlet mechanism shuts off the water.

[0032] In this embodiment, a contact terminal 23 is provided on the base 2, and the contact terminal 23 is electrically connected to the circuit board 4. The signal output end of the liquid level sensor 14 is exposed. When the water flosser 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 the need for additional connection leads and making the overall structure simpler. 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 to this. In other embodiments, the signal output end of the liquid level sensor 14 is visible at the outer side of the water tank 11. The number of liquid level sensors 14 is multiple, specifically two, but is not limited to this. The number of contact terminals 23 is one. The water flosser 1 has multiple placement angles, which makes it more convenient for users to use. When placing it, only one of the liquid level sensors 14 needs to be in contact with the contact terminal 23.

[0033] As a preferred structure, the base 2 has a pressable portion, and the circuit board 4 is connected to a micro switch 41. When the pressable portion is pressed, the micro switch 41 is triggered, so that the circuit board 4 controls the water inlet mechanism (i.e., the water inlet solenoid valve 5) to open the water inlet. Specifically, in this embodiment, the base 2 includes a cover 21 and a bottom shell 22. The cover 21 is pressably connected to the bottom shell 21 and constitutes the pressable portion. The cover 21 is used to support the water flosser and is provided with the above-mentioned water passage 211. The above-mentioned contact terminal 23 is installed, and the cover 21 can be pressed downward by the water flosser 1. The cover 21 is connected to a reset elastic member 24 for providing the cover 21 with an upward reset. The reset elastic member 24 is specifically a spring. The bottom shell 22 is assembled from two parts, but is not limited thereto. In other embodiments, the pressable portion on the base is a button structure installed on the base.

[0034] In this embodiment, the present invention further includes a drainage mechanism for draining residual water from the water tank 11. The water inlet of the drainage mechanism is connected to the water passage 211 of the base 2 and is electrically connected to the circuit board 4. The drainage mechanism is preferably a water pump 3, which can pump out residual water from the water tank 11 when negative pressure occurs in the water tank 11. In other embodiments, the drainage mechanism is a drainage solenoid valve, etc. Specifically, the water passage 211 of the base 2 connects the water inlet of the drainage mechanism (i.e., the water pump 3) and the water outlet of the water inlet mechanism (i.e., the water inlet solenoid valve 5) via a three-way waterway 6. Furthermore, the circuit board 4 controls the drainage mechanism (i.e., the water pump 3) to start pumping water when the liquid level sensor 14 continuously detects a water level signal (the water level signal is preferably a preset low water level signal, but is not limited thereto. In other embodiments, the water level signal can be either a low water level signal or a high water level signal, so that the utility model can not only discharge the residual water remaining in the water tank 11 after the water irrigator is used, but also discharge the high water level water retained in the water tank when the water irrigator is not used in time, thereby avoiding the growth of bacteria) and the duration exceeds a preset value, and the circuit board 4 controls the drainage mechanism (i.e., the water pump 3) to stop pumping water when the liquid level sensor 14 does not detect a water level signal.

[0035] In this embodiment, a first magnet 16 is mounted at the bottom of the water tank 11, and a Hall sensor (not shown) is mounted on the circuit board 4. When the water irrigator 1 is placed on the base 2, the Hall sensor senses the first magnet 16 and sends a signal to the circuit board 4 to open the water inlet mechanism (i.e., the water inlet solenoid valve 5). When the water irrigator 1 is lifted while the water tank 11 is filling, the Hall sensor no longer senses the first magnet 16 and sends a signal to the circuit board 4 to close the water inlet mechanism (i.e., the water inlet solenoid valve 5). This prevents water from gushing out when the water irrigator 1 is accidentally lifted.

[0036] In this embodiment, when the oral irrigator 1 is placed on the base 2, a positioning structure is provided between the two to provide positioning for the oral irrigator 1. The positioning structure specifically includes a first magnet 16 disposed at the bottom of the water tank 11 and a second magnet 25 disposed on the base 2. When the oral irrigator is placed on the base 2, the first magnet 16 and the second magnet 25 are magnetically attracted to each other. The first magnet 16 that cooperates with the second magnet 25 is similar to the first magnet 16 that cooperates with the Hall sensor described above, but is not limited thereto.

[0037] The present invention further includes a wireless charging module 26 , which is disposed on the base 2 and can charge the core portion 12 and / or the circuit board 4 of the oral irrigator when the oral irrigator 1 is placed on the base 2 .

[0038] The utility model is a tooth flushing device with automatic water injection function, and its working principle is as follows:

[0039] When the water irrigator 1 is placed on the base 2 and the water tank 11 needs to be filled with water, the water irrigator 1 is pressed downward, causing it to press downward on the cover 21 of the base 2, triggering the microswitch 41 below the cover 21. The circuit board 4 controls the water inlet solenoid valve 5 to open, and water is discharged from the outlet of the water inlet solenoid valve 5 and flows into the water tank 11 through the water passage 211 of the cover 21 and the water hole 111 of the water tank 11. During the water tank 11 filling process, if the water irrigator 1 is accidentally lifted, the Hall effect sensor on the circuit board 4 will not sense the first magnet 16 on the water tank 11 and will send a signal to the circuit board 4, causing the circuit board 4 to control the water inlet solenoid valve 5 to close. When the liquid level sensor 14 detects that the water level in the water tank 11 has reached the preset maximum water level, the circuit board 4 controls the water inlet solenoid valve 5 to close, thereby completing the automatic water filling process of the water tank 11.

[0040] When the water flosser 1 is used up and put back into the base 2, if the liquid level sensor 14 detects that the water level in the water tank 11 is at a preset low water level and the duration exceeds the preset value, it means that there is residual water in the water tank 11, then the circuit board 4 starts the water pump 3, so that the water pump 3 pumps out the residual water in the water tank 11 until the residual water in the water tank 11 is drained.

[0041] The utility model provides a tooth flushing device with an automatic water filling function, which can not only automatically fill water, but also automatically discharge residual water in the water tank 11, making it very convenient for users to use, and can ensure that the amount of water filled in the water tank 11 each time is constant, reducing bacteria breeding and water leakage problems.

[0042] See Figure 1-Figure 5As shown, a water outlet device of the present invention includes a faucet 7 and the aforementioned tooth flushing device with automatic water filling function of the present invention. The faucet 7 and the base 2 are arranged on the same countertop 40. The water in the water tank 11 comes from the mixed water output by the mixing valve core 71 provided in the faucet 7. That is, the water inlet end of the water inlet solenoid valve 5 is connected to 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 water tank 11 can obtain constant temperature water suitable for tooth flushing each time it is filled with water.

[0043] In this embodiment, the water outlet device of the present invention also includes a water outlet solenoid valve 8, the water inlet end of the water outlet solenoid valve 8 is connected to the mixed water outlet end of the mixing valve core 71, and the water outlet end of the water outlet solenoid valve 8 is connected to the water outlet of the faucet 7 through the water outlet pipe to control whether the faucet 7 discharges water. A button switch 73 is installed at the water outlet of the faucet 7. The button switch 73 and the water outlet solenoid valve 8 are electrically connected to another circuit board 9, so that when the button switch 73 is pressed, a signal can be sent to the other circuit board 9, so that the other circuit board 4 controls whether the water outlet solenoid valve 8 is opened or not. The button switch 73 can be replaced by a sensor, such as an infrared sensor. The above-mentioned water pump 3, water inlet solenoid valve 5, and water outlet solenoid valve 8 are installed in the same support 30, and the support 30 is located below the table 40.

[0044] In this embodiment, the base 72 of the faucet 7 is equipped with a light strip 10 and a light guide plate 20. Light emitted by the light strip 10 is emitted through the light guide plate 20, making the light softer. The light strip 10 can be electrically connected to another circuit board 9, which can control its on and off. The base 72 of the faucet 7 is mounted together with the base 2 of the dental flossing device.

The parts not involved (such as the structure and working principle of the core part 12 of the water irrigator 1, the water stopper 15, etc.) are the same as those in the prior art or can be implemented using the prior art.

[0047] The above embodiments are only used to further illustrate a tooth flushing device and a water outlet device with an automatic water filling function of the present invention, but the present invention is not limited to the embodiments.
