Description

Technical Field

[0001] The present invention relates to the technical field of teeth cleaning equipment, and in particular provides a teeth flushing device. Background Art

[0002] With the improvement of living standards, people's awareness of oral care has gradually increased, and the oral cleaning tools on the market have become more and more diverse. Among them, the water flosser has become one of the essential small appliances in the home as a substitute for traditional dental floss. Its basic working principle is to use the pump to draw water from the water tank and spray high-pressure pulse water through the nozzle hundreds or even thousands of times per minute to clean food residues and dental plaque in the gaps between teeth and massage gums, etc., to improve the oral environment.

[0003] For existing pulse-type water flossers, pulse and water pressure are the key mechanisms for their cleaning effect. In order to achieve the cleaning effect, the water flow strength of the water flosser must be guaranteed, which requires that the connection between the nozzle and the main body of the water flosser must be firm to prevent the nozzle from separating from the main body of the water flosser when the product is in use.

[0004] There are two common nozzle connection methods on the market: button lock buckle type and magnetic suction type. The button lock buckle type is to install a button lock buckle inside the connection hole of the head of the water flosser body, and a groove is provided at the connection below the nozzle. When connecting, aim the nozzle at the connection hole of the water flosser and press it down hard. The locking buckle of the body is pushed out by the nozzle rod and stuck in the nozzle groove, so as to achieve the purpose of fixing the nozzle. When removing the nozzle, you need to hold the water flosser body with one hand, press the nozzle release button with your finger to make the locking buckle come out of the nozzle groove, and pull the nozzle out of the connection hole with the other hand. The entire installation / removal process of the button lock buckle structure is slightly inconvenient, and there is a phenomenon of accidental contact during the process, and the interactive experience is poor. The magnetic suction type is to install magnets at the connection between the nozzle and the water flosser, and use the principle of opposite magnets attracting each other to achieve a natural connection between the nozzle and the main water flosser. However, considering the high-pressure impact of the water flow of the water flosser, the magnetic attraction between the magnets is usually designed to be very strong to prevent the nozzle from being separated from the water flosser body when the product is used, which has the disadvantage of being difficult to remove. Although some structures have been improved through the design, with the two magnets symmetrically arranged with the N pole and the S pole respectively, connected by the principle of opposites attracting each other, and separated by the principle of likes repelling each other, thus solving the disadvantage of being difficult to remove, there is a certain inconvenience in adjusting and changing the relative positions of the two magnets. The repulsion of likes can also cause the nozzle to suddenly separate from the main body of the water flosser, making it easy to fall, and there is also the possibility of accidental contact. Summary of the invention

[0005] The object of the present invention is to provide a water flosser, aiming to solve the problem that the nozzle of the existing water flosser is connected to the main body and is difficult to remove and easy to fall off.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] The present invention proposes a water flosser, comprising a water flosser body and a nozzle body detachably connected to the water flosser body, the water flosser body having an electromagnetic device, the nozzle body having a magnetic attraction structure that is magnetically attracted to the electromagnetic device, the nozzle body being connected to the water flosser body, and the magnetic attraction structure being locked on the water flosser body when the electromagnetic device is powered on.

[0008] Beneficial effects of the present invention: The water flosser provided by the present invention utilizes an electromagnetic device and a magnetic attraction structure for magnetic connection. When the water flosser is powered on and used, the electromagnetic device is powered on to generate a magnetic field. At this time, the electromagnetic device has a strong magnetic attraction force on the magnetic attraction structure. When the water flosser is used, a high-pressure water flow enters the nozzle body from the water flosser body and is ejected. The water flosser body with the electromagnetic device attracts the nozzle body with the magnetic attraction structure through magnetic force, so that the nozzle body is not easily impacted and dropped by the high-pressure water flow. When the water flosser is used and the power is turned off, the electromagnetic device is immediately demagnetized, and the magnetic field is weakened, so that the magnetic attraction between the magnetic attraction structure on the nozzle body and the electromagnetic device on the water flosser body is weakened, thereby facilitating the separation of the nozzle body from the water flosser body, effectively solving the problem that the traditional water flosser is not easy to remove after being fixedly connected by two magnets. At the same time, after the power is turned off, the magnetic attraction structure and the electromagnetic device have a certain magnetic attraction force to ensure that the nozzle body and the water flosser body will not be accidentally separated during daily taking.

[0009] In one embodiment, the oral irrigator body includes a main body and a connecting structure rotatably connected to the main body, the electromagnetic device is disposed in the connecting structure, and the nozzle body is detachably connected to the connecting structure.

[0010] By adopting the above technical solution, the nozzle body is connected to the main body by using the connecting structure, and the position of the nozzle body can be adjusted by turning the knob connecting structure.

[0011] In one embodiment, one end of the nozzle body extends outward to form a connecting rod, the magnetic attraction structure includes a magnetic attraction part installed on the connecting rod, and a plug-in channel cooperating with the connecting rod is opened on the connecting structure part. The connecting rod is inserted into the plug-in channel and connected to the main body.

[0012] By adopting the above-mentioned technical solution, by inserting the connecting rod of the nozzle body into the plug-in channel of the connecting structure, and by plugging in with an electromagnetic device to magnetically connect the magnetic attraction part, when the water flosser is powered on and used, the nozzle body and the connecting structure are reliably connected to ensure that the nozzle body will not fall off the connecting structure when the high-pressure water flows from the main body into the nozzle body and sprays out.

[0013] In one embodiment, the magnetic attraction member is disposed at one end of the connecting rod close to the main body.

[0014] By adopting the above technical solution, the magnetic attraction piece is arranged at one end of the connecting rod close to the main body. When the connecting rod is inserted into the plug-in channel, the magnetic attraction piece is also in the plug-in channel, which not only ensures the magnetic attraction between the magnetic attraction piece and the electromagnetic device, but also makes the center of gravity of the entire nozzle body shift toward the plug-in channel, thereby preventing the nozzle body from breaking due to accidental falling.

[0015] In one embodiment, the magnetic attraction structure is a metal connecting rod disposed at one end of the nozzle body, and a plug-in channel cooperating with the metal connecting rod is opened on the connecting structure, and the metal connecting rod is inserted into the plug-in channel and connected to the main body.

[0016] By adopting the above-mentioned technical solution, the magnetic attraction structure adopts a metal connecting rod and is arranged at one end of the nozzle body. By inserting the metal connecting rod into the plug-in channel of the connecting structure, the metal connecting rod is magnetically connected with an electromagnetic device in the form of plug-in, so that when the water flosser is powered on and used, the nozzle body and the connecting structure are reliably connected to ensure that the nozzle body will not fall off the connecting structure when the high-pressure water flows from the main body into the nozzle body and is sprayed out.

[0017] In one embodiment, a clamping groove is provided on the outer circumference of the connecting rod, and a clamping ring matching the clamping groove is provided on the inner side wall of the plug-in channel.

[0018] By adopting the above technical solution, by setting a slot on the outside of the connecting rod and setting a snap ring on the inner side wall of the plug-in channel, when the connecting rod is inserted into the plug-in channel, the slot will also be clamped on the snap ring. The cooperation between the slot and the snap ring can help strengthen the connection between the nozzle body and the connecting structure. At the same time, when the water flosser is powered off, it is ensured that the nozzle body is not easy to fall off from the connecting structure; when the electromagnetic device and the magnetic attraction structure are repelled by the same polarity by reverse power supply to facilitate the removal of the nozzle body, the cooperation connection between the slot and the snap ring prevents the nozzle body from popping out suddenly.

[0019] In one embodiment, the connecting structure includes a lower structure connected to the oral flosser body and an upper structure rotatably connected to the lower structure, and the electromagnetic device is disposed in the upper structure.

[0020] By adopting the above-mentioned technical solution, the connecting structure is set as a lower structure connected to the water flosser body and an upper structure rotatably connected to the lower structure. The lower structure can connect the connecting structure to the body, and the upper structure can be rotated on the upper structure to adjust the position of the nozzle body.

[0021] In one embodiment, the upper structure is provided with a groove, and the electromagnetic device is installed in the groove.

[0022] By adopting the above technical solution, by providing a groove on the upper structure to accommodate the electromagnetic device, the installation and disassembly operations of the electromagnetic device are simpler, thereby facilitating subsequent maintenance and repair work.

[0023] In one embodiment, a guide structure is provided at one end of the upper structure for connecting to the nozzle body.

[0024] By adopting the above-mentioned technical solution and setting a guiding structure on the upper structural member, when installing the nozzle body, it is only necessary to load the nozzle body onto the upper structural member. The guiding structure can guide the nozzle body into the installation position when installing the nozzle body, thereby facilitating the installation operation of the nozzle body.

[0025] In one embodiment, a friction structure is provided on the outer periphery of the upper structure.

[0026] By adopting the above technical solution, by setting a friction structure on the outer periphery of the upper structure, when the upper structure is twisted, the friction structure can increase the friction force of the upper structure by hand, thereby facilitating the rotation and twisting of the upper structure to adjust the position of the nozzle.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The connection methods between the nozzle of a traditional water flosser and the main body of the water flosser are generally button locking buckle connection and magnetic connection. When removing the nozzle of a water flosser with a button locking buckle connection, you need to hold the main body of the water flosser with one hand, press the nozzle release button with your finger to make the locking buckle disengage from the nozzle groove, and use the other hand to pull the nozzle out of the connection hole. The entire process of removing the nozzle is relatively complicated, and there is a phenomenon of accidental contact during the process, and the interactive experience is poor. For water flossers with magnetic connections, the magnetic attraction of the magnet between the main body of the water flosser and the nozzle is usually designed to be very strong, considering the high-pressure impact of the water flow of the water flosser, to prevent the nozzle from accidentally falling off due to the high-pressure water flow when the water flosser is working, which makes it difficult to disassemble the nozzle and the main body of the water flosser. Although some structures have been improved through the design, with the two magnets symmetrically arranged with the N pole and the S pole respectively, connected by the principle of opposites attracting each other, and separated by the principle of likes repelling each other, thus solving the disadvantage of being difficult to remove, there is a certain inconvenience in adjusting and changing the relative positions of the two magnets. The repulsion of likes can also cause the nozzle to suddenly separate from the main body of the water flosser, making it easy to fall, and there is also the possibility of accidental contact.

[0038] Please refer to Figures 1 to 3 In response to the above-mentioned problems, the present application proposes a water flosser 100, comprising a water flosser body 10 and a nozzle body 20 detachably connected to the water flosser body 10, the water flosser body 10 having an electromagnetic device 30, the nozzle body 20 having a magnetic attraction structure 40 magnetically attracted to the electromagnetic device 30, the nozzle body 20 being connected to the water flosser body 10, and the magnetic attraction structure 40 being locked on the water flosser body 10 when the electromagnetic device 30 is powered on.

[0039] The electromagnetic device 30 and the magnetic attraction structure 40 are used for magnetic connection. When the oral irrigator 100 is powered on and used, the electromagnetic device 30 is powered on to generate a magnetic field. At this time, the electromagnetic device 30 has a strong magnetic attraction force on the magnetic attraction structure 40 to form a locked state, that is, the nozzle body 20 is locked on the oral irrigator body 10 by a strong magnetic attraction force in the charging state. When the oral irrigator 100 is used, the high-pressure water flow enters the nozzle body 20 from the oral irrigator body 10 and sprays out. The oral irrigator body 10 with the electromagnetic device 30 uses magnetic force to absorb the nozzle body 20 with the magnetic attraction structure 40 to form a locking effect, so that the nozzle body 20 is not easily impacted and dropped by the high-pressure water flow. When the water flosser 100 is powered off after use, the electromagnetic device 30 is immediately demagnetized and the magnetic field is weakened, so that the magnetic attraction between the magnetic attraction structure 40 on the nozzle body 20 and the electromagnetic device 30 on the water flosser body 10 is weakened, and the locking state is released, so that the nozzle body 20 and the water flosser body 10 can be easily separated, eliminating the operation process of rotating and adjusting the magnetic attraction structure, simplifying the operation process, reducing the probability of accidental contact during unnecessary operations, and effectively solving the problem that the traditional water flosser 100 is not easy to remove after being fixedly connected by two magnets. At the same time, the water flosser 100 of the present invention eliminates the nozzle release button design, avoids the problem of dirt and grime between the water flosser body 10, and is more hygienic and healthy. At the same time, after the power is turned off, the magnetic attraction structure 40 and the electromagnetic device 30 have a certain magnetic attraction force to ensure that the nozzle body 20 and the water flosser body 10 will not be accidentally separated during daily handling.

[0040] Specifically, the electromagnetic device 30 can be an electromagnet or an electromagnetic coil, or a device that can generate a magnetic field by energizing. In this embodiment, an electromagnet is used as the electromagnetic device 30. Among them, the iron core of the electromagnet is soft magnetic, so that after the power is turned off, the electromagnet still has a certain magnetism. Silicon steel sheets can be selected as soft magnetic materials, and permanent magnets or metal sheets can be used as materials for the magnetic attraction structure 40. When the nozzle needs to be removed, the switch of the water flosser 100 is turned off, so that the electromagnetic device 30 is disconnected from the power supply, and the iron core of the electromagnetic device 30 is soft magnetic, which is demagnetized at the same time as the power is turned off, and the adsorption effect on the nozzle magnet or metal sheet is weakened, and the nozzle body 20 is easy to be removed, which solves the cumbersome operation of the existing fixed magnetic attraction fixing method that is not easy to remove and the nozzle needs to be rotated to adjust the position to remove. When the magnetic attraction structure 40 uses a permanent magnet, in order to more conveniently disassemble the nozzle body 20, the electromagnetic device 30 can also be reversely energized to produce opposite magnetic poles, so that according to the principle of like poles repel each other, the nozzle body 20 can automatically fall off from the water flosser body 10.

[0041] It can be understood that the water flosser 100 of the present invention changes with the adjustment of the water flossing intensity mode, that is, the adjustment of the current size of the water flosser 100, and the current passed through the electromagnetic device 30 also changes accordingly, and then the magnetic field strength generated by the electromagnetic device 30 changes accordingly, and the adsorption capacity of the nozzle body 20 also changes accordingly. The stronger the intensity of the water flossing mode, the greater the current passing through the electromagnetic device 30, the greater the magnetic field strength, and the stronger the adsorption capacity of the nozzle body 20. At this time, the water flow with a greater pressure from the water flosser body 10 into the nozzle body 20 will not flush the nozzle body 20 down and cause an accident, which effectively ensures the safety performance of the water flosser 100.

[0042] Please refer to Figures 1 to 3 In one embodiment, the oral irrigator body 10 includes a main body 11 and a connecting structure 12 rotatably connected to the main body 11, the electromagnetic device 30 is disposed in the connecting structure 12, and the nozzle body 20 is detachably connected to the connecting structure 12. The nozzle body 20 and the connecting structure 12 are connected together by the magnetic attraction between the electromagnetic device 30 and the magnetic attraction structure 40. Since the connecting structure 12 is rotatable, when the position of the nozzle body 20 needs to be adjusted, the nozzle body 20 will also rotate by rotating the connecting structure 12, thereby achieving the effect of adjusting the position of the nozzle body 20, with a simple structure and convenient operation.

[0043] Please refer to the figure. In one embodiment, one end of the nozzle body 20 extends outward to form a connecting rod 21. The magnetic attraction structure 40 includes a magnetic attraction part installed on the connecting rod. The connecting structure 12 is provided with a plug-in channel 101 that cooperates with the connecting rod 21. The connecting rod 21 is inserted into the plug-in channel 101 and connected to the main body 11. It can be understood that the connecting rod 21 has a hollow structure to connect the main body 11 to introduce the magnetic attraction part into the water flow. By inserting the connecting rod 21 of the nozzle body 20 into the plug-in channel 101 of the connecting structure 12, the magnetic attraction part is connected by the electromagnetic device 30 in the form of plug-in, so that when the water flosser 100 is powered on and used, the nozzle body 20 is reliably connected to the connecting structure 12 to ensure that the nozzle body 20 will not fall off from the connecting structure 12 when the high-pressure water flow enters the nozzle body 20 from the main body 11 and sprays out. It can be understood that one end of the nozzle body 20 is a water spray end, and the other end of the nozzle body 20 is a water inlet end, and the water spray end and the water inlet end are connected through a water spray pipe inside the nozzle body 20. When the connecting rod 21 is inserted into the plug-in channel 101, the water inlet end at the end of the connecting rod 21 is connected to the main body 11, and the main body 11 transports the water in the water tank from the water inlet end to the nozzle body 20 through the action of the pump body, and sprays it out from the water spray end through the water spray pipe to achieve the flushing operation. Among them, the magnetic suction component can be arranged inside the connecting rod 21 in the form of injection molding, or the magnetic suction component can be installed or wrapped on the outer surface of the connecting rod 21, or the magnetic suction component can be installed or wrapped on the inner surface of the hollow structure of the connecting rod 21. The specific installation form of the magnetic suction component and the connecting rod 21 can be determined by actual production needs.

[0044] Please refer to Figures 1 to 3 In one embodiment, the magnetic attraction member is disposed at one end of the connecting rod 21 close to the main body 11. The magnetic attraction member is disposed at one end of the connecting rod 21 close to the main body 11. When the connecting rod 21 is inserted into the plug-in channel 101, the magnetic attraction member is also in the plug-in channel 101, which not only ensures the magnetic attraction between the magnetic attraction member and the electromagnetic device 30, but also makes the center of gravity of the entire nozzle body 20 shift toward the plug-in channel 101, thereby preventing the nozzle body 20 from breaking due to accidental falling.

[0045] In another embodiment, the magnetic attraction structure 40 is a metal connecting rod disposed at one end of the nozzle body 20, and a plug-in channel 101 cooperating with the metal connecting rod is provided on the connecting structure 12, and the metal connecting rod is passed through the plug-in channel 101 and connected to the main body 11. The magnetic attraction structure 40 adopts a metal connecting rod and is disposed at one end of the nozzle body 20, and the metal connecting rod is inserted into the plug-in channel 101 of the connecting structure 12, and the metal connecting rod is magnetically connected with the electromagnetic device 30 in the form of plug-in, so that when the water flosser 100 is powered on and used, the nozzle body 20 is reliably connected to the connecting structure 12, ensuring that the nozzle body 20 will not fall off from the connecting structure 12 when the high-pressure water flows from the main body 11 into the nozzle body 20 and sprays out.

[0046] Please refer to Figures 1 to 3 In one embodiment, a slot 211 is provided on the outer circumference of the connecting rod 21, and a snap ring 102 cooperating with the slot 211 is provided on the inner side wall of the plug-in channel 101. By cooperating between the slot 211 of the connecting rod 21 and the snap ring 102 of the plug-in channel 101, when the connecting rod 21 is inserted into the plug-in channel 101, the slot 211 will also be clamped on the snap ring 102. The cooperation between the slot 211 and the snap ring 102 can help strengthen the connection between the nozzle body 20 and the connecting structure 12. At the same time, when the water flosser 100 is powered off, it is ensured that the nozzle body 20 is not easy to fall off from the connecting structure 12; when the electromagnetic device 30 and the magnetic attraction structure 40 are repelled by the same polarity by reverse power supply to facilitate the removal of the nozzle body 20, the cooperation between the slot 211 and the snap ring 102 prevents the nozzle body 20 from popping out suddenly.

[0047] Please refer to Figures 1 to 3 In one embodiment, the electromagnetic device 30 is a hollow ring structure around the plug-in channel 101. The electromagnetic device 30 is set as a hollow ring structure, that is, the electromagnetic device 30 is set around the plug-in channel 101. When the connecting rod 21 is inserted into the plug-in channel 101, that is, the magnetic attraction structure 40 is in the plug-in channel 101, after the water flosser 100 is powered on, the electromagnetic device 30 can fully absorb the magnetic attraction structure 40 of the connecting rod 21 to ensure that the nozzle body 20 and the connecting structure 12 are firmly connected.

[0048] Please refer to Figures 1 to 3 In one embodiment, the connecting structure 12 includes a lower structure 121 connected to the main body 11 of the oral irrigator 100 and an upper structure 122 rotatably connected to the lower structure 121, and the electromagnetic device 30 is disposed in the upper structure 122. The connecting structure 12 is configured as the lower structure 121 connected to the main body 11 of the oral irrigator 100 and the upper structure 122 rotatably connected to the lower structure 121, the lower structure 121 can connect the connecting structure 12 to the main body 11, and the upper structure 122 can rotate on the upper structure 122 to adjust the position of the nozzle body 20.

[0049] Please refer to Figures 1 to 3 In one embodiment, the upper structure 122 is provided with a groove 123, and the electromagnetic device 30 is installed in the groove 123. By providing the groove 123 on the upper structure 122 to accommodate the electromagnetic device 30, the electromagnetic device 30 can be aligned with the groove 123 for installation, and the electromagnetic device 30 can be directly taken out of the groove 123 when maintenance, overhaul or replacement is required, so that the installation and disassembly operation of the electromagnetic device 30 is more convenient, and it is also convenient for later maintenance and overhaul work.

[0050] Please refer to Figures 1 to 3In one embodiment, a guide structure 124 is provided at one end of the upper structure 122 for connecting the nozzle body 20. Specifically, the guide structure 124 can be a chamfered protrusion of the upper structure 122 away from one end of the lower structure 121. When the nozzle body 20 is installed on the upper structure 122, the chamfered protrusion can guide the nozzle body 20 to align the connecting rod 21 with the plug-in channel 101 for installation. Therefore, by providing the guide structure 124 on the upper structure 122, when installing the nozzle body 20, it is only necessary to load the nozzle body 20 onto the upper structure 122. The guide structure 124 can guide the nozzle body 20 into the installation position when installing the nozzle body 20, which facilitates the installation operation of the nozzle body 20.

[0051] Please refer to Figures 1 to 3 In one embodiment, a friction structure 125 is provided on the outer periphery of the upper structure 122. Specifically, the friction structure 125 can be a threaded structure or a protruding structure provided on the outer periphery of the upper structure 122, and the friction coefficient between the hand and the outer periphery of the upper structure is increased by the friction structure 125. By providing the friction structure 125 on the outer periphery of the upper structure 122, when the upper structure 122 is twisted, the friction structure 125 can increase the friction force of the hand holding the upper structure 122, thereby facilitating the twisting of the upper structure 122 to adjust the position of the nozzle.
