Description

Technical Field

[0001] This utility model relates to the technical field of oral hygiene products, and in particular to a water flosser. Background Technology

[0002] As is well known, oral irrigators use a pump to generate high-pressure pulsed water to flush the mouth, removing small food debris and harmful bacteria adhering to teeth and gums. For deeper and healthier dental care, mouthwash is added to the water in the irrigator. To facilitate adding mouthwash, current oral irrigators are equipped with a filling device to store it, which the user adds to the water tank. However, most current filling devices are secured with screws or clips, requiring forceful disassembly to install or remove. This method can easily damage the connection between the filling device and the main unit, causing the device to become loosely attached and prone to detaching upon reassembly, thus affecting user experience.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] See attached document Figures 1 to 15 A dental flosser 100 is provided in this embodiment of the present invention.

[0048] The oral irrigator 100 includes:

[0049] The main body of the tooth-flushing device 10 has a water storage chamber 21 for storing water and a liquid outlet 15.

[0050] A pump body 14 is installed on the main body 10 of the flushing device. When the pump body 14 is driven, it draws the liquid in the water storage chamber 21 and sends the liquid out from the liquid outlet 15.

[0051] A liquid filling mechanism 7 is detachably mounted on the oral irrigator body 10. The liquid filling mechanism 7 has a liquid storage chamber 711 for storing oral cleaning liquid. When the liquid filling mechanism 7 is assembled onto the oral irrigator body 10, the liquid storage chamber 711 is connected to the water storage chamber 21. The liquid in the liquid storage chamber 711 is configured to transfer oral cleaning liquid to the water storage chamber 21 when the user operates the liquid filling mechanism 7 or the main unit.

[0052] The magnetic attraction mechanism 4 is configured to attract the liquid filling mechanism 7 onto the oral irrigator 10 when the liquid filling mechanism 7 is close to the oral irrigator 10.

[0053] Lock 5 is configured to lock the liquid filling mechanism 7 onto the flushing body 10;

[0054] Release mechanism 6 is configured to move latch 5 during user operation to loosen the connection between liquid filling mechanism 7 and flushing body 10. Release mechanism 6 is also configured to return latch 5 to its initial state when the user releases the operation.

[0055] This embodiment features a liquid-filling mechanism 7, allowing users to add oral cleaning fluid to the water reservoir 21, thus enabling the liquid in the reservoir 21 to clean the oral cavity. Furthermore, a locking mechanism 5 secures the liquid-filling mechanism 7 to the water flosser body 10 when it is assembled, allowing users to directly add oral cleaning fluid to the reservoir during use. A release mechanism 6 allows the locking mechanism 5 to disengage the liquid-filling mechanism 7 from the water flosser body 10 when operated by the user, enabling removal of the liquid-filling mechanism 7 without damaging the locking mechanism 5. This solves the problems of damage to the connection structure caused by forceful disassembly of existing liquid-filling devices and water flosser main units, as well as the problem of insecure reinstallation of existing liquid-filling devices and water flosser main units. Furthermore, by configuring the magnetic suction mechanism 4, when the latch 5 releases the liquid filling mechanism 7 from the floss body 10, it can prevent the liquid filling mechanism 7 from falling off, thus protecting the liquid filling mechanism 7. Moreover, when the liquid filling mechanism 7 is close to the floss body 10, it can be attracted to the floss body 10, which can increase the stability of the connection between the liquid filling mechanism 7 and the floss body 10.

[0056] Specifically, the oral irrigator 100 also includes a pump body 14, which is used to draw liquid from the water storage chamber 21 and send the liquid out from the outlet 15 when driven, so as to form a water flow with a certain pressure to achieve the function of rinsing teeth.

[0057] In one embodiment, the pump body 14 and the liquid outlet 15 are disposed on the main body 10 of the oral irrigator. The liquid outlet 15 can be directly adapted to different nozzles 30 for use by the user to rinse and clean teeth. This oral irrigator is portable and convenient for handheld use. Of course, in other embodiments, the pump body 14 and the liquid outlet 15 are also disposed on the main body 10 of the oral irrigator, but the oral irrigator 100 also includes a handle. The liquid outlet 15 is connected to the handle through a hose, and different nozzles are disposed on the handle, thus constituting a household oral irrigator. The water storage chamber 21 of this oral irrigator has a large water storage capacity. When in use, the user picks up the handle, and the pump body 14 is driven to draw liquid from the water storage chamber 21 and deliver it sequentially through the liquid outlet 15, the hose, and the handle from the nozzle to form a water flow with a certain pressure, thereby achieving the function of rinsing teeth.

[0058] The magnetic attraction mechanism 4 includes a first magnetic attraction element 41 and a second magnetic attraction element 44 that is attracted to the first magnetic attraction element 41. The first magnetic attraction element 41 is disposed on the flossing body 10, and the second magnetic attraction element 44 is disposed on the liquid filling mechanism 7. Specifically, both the first magnetic attraction element 41 and the second magnetic attraction element 44 are permanent magnets or magnetizable elements; or, one of the first magnetic attraction element 41 and the second magnetic attraction element 44 is a magnet, and the other is a metal part attracted to the magnet. The metal part can be an iron block, an iron sheet, or an alloy made of iron, nickel, etc. In the preferred embodiment, both the first magnetic attraction element 41 and the second magnetic attraction element 44 are neodymium iron boron magnets.

[0059] In one embodiment, the flossing body 10 has a first mounting groove 321 for accommodating the liquid dispensing mechanism 7, which is placed within the first mounting groove 321 during assembly with the flossing body 10. The first mounting groove 321 improves the stability of the liquid dispensing mechanism 7 during assembly with the flossing body 10.

[0060] In one embodiment, the magnetic suction mechanism 4 further includes a first elastic member 43 disposed on the flossing body 10. The first elastic member 43 is configured to push the first magnetic suction member 41 to move when the latch 5 releases the connection between the liquid filling mechanism 7 and the flossing body 10. When the first magnetic suction member 41 moves, the liquid filling mechanism 7 is at least partially pushed out of the first mounting groove 321 by the second magnetic suction member 44. That is, when the user needs to remove the liquid filling mechanism 7 from the flossing body 10, the latch 5 is moved by operating the release mechanism 6 to release the connection between the liquid filling mechanism 7 and the flossing body 10. Under the action of the first elastic member 43, at least part of the liquid filling mechanism 7 can be pushed out of the first mounting groove 321. In this state, it is convenient for the user to remove the liquid filling mechanism 7 from the first mounting groove 321. Specifically, the first elastic member 43 can be a spring or a spring sheet, etc.

[0061] In the above embodiment, the magnetic suction mechanism 4 may further include a push block 42. The punch body 10 has a movable cavity 331 for limiting the push block 42 and a first through hole 327 that communicates with both the movable cavity 331 and the first mounting groove 321. The first magnetic suction member 41 is disposed on the push block 42, and the push block 42 has a second mounting groove 421 for accommodating the first elastic member 43. A limiting protrusion 422 is provided on the periphery of the push block 42. The limiting protrusion 422 is placed in the movable cavity 331, and the width of the first through hole 327 is smaller than the width of the movable cavity 331, so that the limiting protrusion 422 can be limited in the movable cavity 331 to limit the push block 42 to be mounted on the punch body 10. The push block 42 is placed in the first through hole 327, and the first elastic member 43 is at least partially placed in the second mounting groove 421. When the second magnetic suction member 44 in the liquid filling mechanism 7 is attracted to the first magnetic suction member 41, and the latch 5 locks the liquid filling mechanism 7 onto the flosser body 10, the first elastic member 43 is compressed and placed in the movable cavity 331. When the latch 5 releases the connection between the flosser body 10 and the liquid filling mechanism 7, without the limitation of the latch 5, the first elastic member 43, under the reset force, drives the first magnetic suction member 41 away from the movable cavity 331 through the push block 42, that is, pushes the first magnetic suction member 41 into the first mounting groove 321, so as to push the liquid filling mechanism 7 at least partially out of the first mounting groove 321. When the first mounting groove 321 is set at the bottom of the flosser body 10, the liquid filling mechanism 7 will not fall directly due to the attraction between the first magnetic suction member 41 and the second magnetic suction member 44. Furthermore, by configuring the push block 42, the structure of the magnetic attraction mechanism 4 can be made more compact, so that the first elastic member 43 can push out the first magnetic attraction member 41 along the depth direction of the active cavity 331, thereby improving the stability of the movement of the first magnetic attraction member 41.

[0062] In one embodiment, the push block 42 is further provided with a third mounting groove 423, and the first magnetic suction member 41 is disposed in the third mounting groove 423 to increase the stability of the connection between the first magnetic suction member 41 and the push block 42, making the connection between the first magnetic suction member 41 and the push block 42 more stable. Furthermore, when the first magnetic suction member 41 is fully embedded in the third mounting groove 423, that is, when the first magnetic suction member 41 is attracted to the second magnetic suction member 44, the push block 42 can also abut against the liquid filling mechanism 7, thereby increasing the contact area between the magnetic suction mechanism 4 and the liquid filling mechanism 7. This allows the first elastic member 43 to directly push the liquid filling mechanism 7 out of the first mounting groove 321 via the push block 42, increasing the force with which the liquid filling mechanism 7 pushes out of the first mounting groove 321.

[0063] Of course, in other embodiments, the first magnetic attractor 41 may also be directly disposed on the surface of the pusher 42.

[0064] In one embodiment, the push block 42 has a second through hole 424, the upper and lower ends of which are connected to the second mounting groove 421 and the third mounting groove 423, respectively. Specifically, when the size of the third mounting groove 423 matches the shape of the first magnetic member 41, the second through hole 424 can be used to vent air when the first magnetic member 41 is assembled into the third mounting groove 423, so as to install the first magnetic member 41 into the third mounting groove 423.

[0065] In one embodiment, to improve the stability of the connection between the second magnetic suction member 44 and the liquid filling mechanism 7, a fourth mounting groove 723 is provided on the liquid filling mechanism 7, and the second magnetic suction member 44 is at least partially placed in the fourth mounting groove 723.

[0066] In one embodiment, the liquid filling mechanism 7 is provided with a positioning protrusion 722, the fourth mounting groove 723 is located on the positioning protrusion 722, the punch body 10 is provided with a positioning groove 3211, the first through hole 327 is located at the bottom of the positioning groove 3211, and the positioning protrusion 722 is placed in the positioning groove 3211 when the liquid filling mechanism 7 and the punch body 10 are assembled, so as to align and assemble the liquid filling mechanism 7 and the punch body 10.

[0067] In one embodiment, there are two magnetic suction mechanisms 4, spaced apart, so that when the latch 5 releases the connection between the liquid filling mechanism 7 and the oral irrigator body 10, the liquid filling mechanism 7 can be more firmly attached to the oral irrigator body 10, and the user can remove the liquid filling mechanism 7 from the oral irrigator body 10 by overcoming the attraction force between the first magnetic suction member 41 and the second magnetic suction member 44. Of course, in other embodiments, the number of magnetic suction mechanisms 4 can also be three, four, etc., and the number of magnetic suction mechanisms 4 is not limited here.

[0068] In one embodiment, the flossing body 10 has a guide strip 322 on the side wall of the first mounting groove 321. The guide strip 322 extends along the direction in which the liquid filling mechanism 7 is installed in the first mounting groove 321. A guide groove 724 is provided on the outer side of the liquid filling mechanism 7 to cooperate with the guide strip 322. When the liquid filling mechanism 7 is installed in the first mounting groove 321, the guide strip 322 is placed within the guide groove 724. By utilizing the cooperation of the guide strip 322 and the guide groove 724, the relative position between the liquid filling mechanism 7 and the flossing body 10 can be limited, and the stability of the connection between the liquid filling mechanism 7 and the flossing body 10 can be improved. In conjunction with the push block 42 and the first elastic member 43, the liquid filling mechanism 7 can be pushed out along the length of the guide strip 322, improving the stability of the relative movement between the liquid filling mechanism 7 and the flossing body 10. Specifically, the number of guide strips 322 is equal to the number of guide grooves 724, and the number of guide strips 322 can be one, two, four, etc.

[0069] In one embodiment, a fifth mounting groove 324 is provided on the main body 10 of the flushing device, and a latch 5 is rotatably mounted on the main body 10 of the flushing device, with at least a portion of the latch 5 placed within the fifth mounting groove 324. A locking block 53 is provided on the latch 5, and a third through hole 326 communicating with the first mounting groove 321 is provided on the main body 10 of the flushing device. A locking opening 725 is provided on the outer wall of the liquid filling mechanism 7. When the latch 5 locks the main body 10 of the flushing device and the liquid filling mechanism 7, the locking block 53 passes through the third through hole 326 and is placed within the locking opening 725 to lock the liquid filling mechanism 7 onto the main body 10 of the flushing device.

[0070] The release mechanism 6 includes a second elastic element 63 and a pressing element 61 disposed on the punch body 10. The two ends of the second elastic element 63 abut against the side wall of the fifth mounting groove 324 and the latch 5, respectively. The second elastic element 63 is located on the side of the latch 5 away from the pressing element 61. When the pressing element 61 is pressed, the latch 5 rotates, causing the locking block 53 to disengage from the locking slot 725, i.e., the latch 5 exits the locking slot 725. In this state, the second elastic element 63 is compressed. Furthermore, when the user releases the pressing element 61, the restoring force of the second elastic element 63 can drive the latch 5 and the pressing element 61 back to their initial positions. An avoidance hole 325 is provided on the outer wall of the punch body 10 to allow the pressing element 61 to be displayed on the outer wall of the punch body 10 for user operation.

[0071] In the above embodiment, the release mechanism 6 further includes a third elastic member 62 disposed in the fifth mounting groove 324. A support portion 328 is disposed in the third mounting groove 423. The two ends of the third elastic member 62 abut against the pressing member 61 and the support portion 328 respectively, that is, the third elastic member 62 is located between the pressing member 61 and the support portion 328. Using the third elastic member 62, after the user presses the pressing member 61, the pressing member 61 can be driven to return to its initial position, thereby reducing the load weight of the second elastic member 63 when it resets, so that the elastic force of the second elastic member 63 can be fully applied to the latch 5, thereby increasing the service life of the second elastic member 63.

[0072] In one embodiment, the latch 5 has a rotating shaft portion 51 on both sides, and a support shaft hole 329 is provided on the support portion 328. The rotating shaft portion 51 is placed in the support shaft hole 329 to realize the rotational connection of the latch 5. The second elastic member 63 is located above the rotating shaft portion 51, that is, the second elastic member 63 and the locking block 53 are respectively located at or near the two ends of the latch 5. In this way, after the latch 5 rotates under the pressing action of the pressing member 61, the second elastic member 63 pushes one end of the latch 5 to move towards the pressing member 61, so that the locking block 53 at the other end of the latch 5 moves away from the pressing member 61, so that the locking block 53 is placed in the first mounting groove 321. That is, when the liquid filling mechanism 7 is assembled onto the punch body 10, the locking block 53 is placed in the locking opening 725 to lock the liquid filling mechanism 7. Specifically, the second elastic member 63 and the third elastic member 62 can both be springs or sheet springs.

[0073] In one embodiment, the first mounting groove 321 is located at the bottom of the flosser body 10, with the opening of the first mounting groove 321 facing the bottom of the flosser body 10. The bottom surface of the locking block 53 is a guide surface 54. The guide surface 54 serves to guide the liquid filling mechanism 7 when it is installed in the first mounting groove 321, so that the locking buckle 5 rotates and drives the locking block 53 to move away from the liquid filling mechanism 7. That is, when the liquid filling mechanism 7 is installed in the first mounting groove 321, the user does not need to operate the release mechanism 6. Under the squeezing action of the liquid filling mechanism 7, the locking buckle 5 rotates, causing the locking block 53 to move away from the liquid filling mechanism 7. When the locking opening 725 is opposite to the locking block 53, the locking buckle 5 returns to its initial position under the reset action of the second elastic member 63, that is, the locking block 53 is placed in the locking opening 725, so as to lock the liquid filling mechanism 7 onto the flosser body 10. Specifically, the guide surface 54 can be an arc surface, an inclined surface, or a combination of an arc surface and an inclined surface.

[0074] In one embodiment, a stop block 52 is provided at the bottom of the latch 5, and an abutment block 320 is formed below the first through hole 327 in the punch body 10. When the latch 5 is in the locked state, it stops rotating by abutting the stop block 52 against the abutment block 320, thereby limiting the initial position of the latch 5.

[0075] In one embodiment, there are two latches 5 and two release mechanisms 6. Each release mechanism 6 corresponds to one latch 5. The two latches 5 are located opposite each other on both sides of the first mounting groove 321. With the help of the locking slots 725 located on both sides of the liquid filling mechanism 7, the liquid filling mechanism 7 can be locked from opposite sides, thereby effectively improving the stability of the connection between the punch body 10 and the liquid filling mechanism 7. Of course, in other embodiments, the number of latches 5 can also be three, four, etc., and one release mechanism 6 can drive one or more latches 5 to rotate simultaneously.

[0076] In one embodiment, the main body 10 of the oral irrigator includes a main unit 1 and a water tank 20 disposed below the main unit 1. A pump body 14 is disposed inside the main unit 1. The main unit 1 also contains a circuit board 12 electrically connected to the pump body 14 and a battery 13 electrically connected to the circuit board 12. A liquid outlet 15 is disposed on the main unit 1. A water storage chamber 21 is located inside the water tank 20. A liquid filling mechanism 7 is detachably disposed at the bottom of the water tank 20 via a latch 5.
