Description

This invention relates to the technical field of oral irrigation, and in particular to an oral irrigator that can inject water from multiple angles.

As living standards improve, people's awareness of oral care is gradually increasing, and the oral cleaning tools on the market are becoming more and more diverse. One of the most popular alternatives to dental floss on the market is the oral irrigator (also known as water flosser). Oral irrigators have already become one of the small home appliances for home health. The basic operating principle of an oral irrigator is as follows. The oral irrigator uses its own pump body to draw water from a tank and sprays a high-pressure pulsed water stream from a nozzle at hundreds to thousands of times per minute. This high-pressure pulsed water stream is used to remove food residue and plaque from between teeth and massage the gums, improving the oral environment.

Patent Document 1 discloses an oral irrigator body and an oral irrigation device, and Patent Document 2 discloses a portable oral irrigator having two water inlets. The water inlets of these two conventional oral irrigators are opened on the upper end surface of the oral irrigator body, and the opening direction of the water inlets is vertically upward. Therefore, when a user tries to supply water to the tank of the oral irrigator body, it is difficult for the user to complete the water receiving operation by placing the oral irrigator body upright under the faucet because the distance between the faucet and the sink is too narrow and the nozzle is inserted into the ceiling part of the oral irrigator body. Therefore, the user has no choice but to complete the water receiving operation by tilting the oral irrigator body, but in this case, water from the faucet cannot be smoothly poured into the tank of the oral irrigator, which is very inconvenient for the user to receive water.

In view of the shortcomings of the conventional technology described above, the technical problem that this invention aims to solve is to provide an oral irrigator that allows the user to conveniently place the oral irrigator body tilted under the faucet to complete the process of receiving water, and that can pour water from multiple angles with less gripping force required when receiving water.

In order to solve the above technical problems, the present invention provides an oral irrigator that can pour water from multiple angles. The oral irrigator includes a main body casing having an angular structure at the top and/or bottom end in the height direction of the main body casing, the angular structure being formed by connecting the main body end wall and the main body side wall of the main body casing, a liquid storage chamber formed inside the main body casing, and a water injection mechanism having a water injection hole and a hole sealing cover that seals the water injection hole. The water injection hole is opened in the angular structure and communicates with the liquid storage chamber. The shape of the hole sealing cover is adapted to the shape of the angular structure to compensate for the oblique cutout area formed by opening the water injection hole. One edge of the hole sealing cover is rotatably connected to the main body casing, and the other edge is engaged with the main body casing.

Preferably, the hole sealing cover includes an end cover portion and a side cover portion that are connected at an angle. One of the end cover portion and the side cover portion is rotatably mounted on the main body casing, and the other of the end cover portion and the side cover portion is engaged with the main body casing.

Preferably, the edge of the end cover portion that is separated from the side cover portion is rotatably connected to the end face wall of the main body, and the edge of the side cover portion that is separated from the end cover portion is engaged with the side wall of the main body.

Preferably, the main body casing is divided into a head casing section and a grip casing section in the vertical direction. The head casing section tapers from top to bottom. The water injection mechanism is provided at the upper end of the head casing section.

Preferably, the gripping casing portion is tapered from top to bottom.

Preferably, a seal layer is provided on the inner surface of the hole sealing lid. The seal layer is fitted into the opening of the water injection hole when the hole sealing lid is engaged with the main casing.

Preferably, the sealing layer has air pressure adjustment holes on its periphery.

Preferably, the water injection mechanism is provided at the upper end of the main body casing. Furthermore, the liquid storage chamber extends downward to the bottom end of the main body casing so that an opening for the liquid storage chamber is formed at the bottom end of the main body casing. The oral irrigator capable of injecting water from multiple angles further includes a bottom cover. The bottom cover is removably provided at the bottom end of the main body casing and seals the opening.

Preferably, the bottom cover includes a sealing engagement plate that engages with the bottom end of the main body casing. The sealing engagement plate is provided with a locking unit that can be returned to its original position, and a removable cover that regulates the position of the locking unit. The locking unit is used to lock the sealing engagement plate to the bottom end of the main body casing.

The removable lid includes a cover plate portion and a blocking plate portion that protrudes from the cover plate portion. The cover plate portion is detachably provided on the sealing engagement plate and seals the attachment/detachment opening. The blocking plate portion abuts against the locking member to prevent the locking member from coming off the slide groove.

As described above, the oral irrigator capable of pouring water from multiple angles according to the present invention has the following beneficial effects. That is, the main innovation of the present invention is the opening design of the water injection hole. The water injection hole is opened in the angular structure and communicates with the liquid storage chamber. In addition, one edge of the hole sealing cover is rotatably connected to the main body casing, and the other edge is engaged with the main body casing. With this design, the user can place the oral irrigator body in an inclined state under the faucet to complete the water intake. In addition, the user's gripping method is closer to the natural position of the wrist, so that the gripping force when receiving water is reduced. In addition, the shape of the hole sealing cover is adapted to the shape of the angular structure to compensate for the oblique cutout area formed by the opening of the water injection hole. As a result, there is no obvious uneven structure on the outer wall of the oral irrigator, so that the entire outer contour of the oral irrigator is more orderly and smooth. Therefore, the oral irrigator of this invention, which can pour water from multiple angles, is convenient for the user to place the oral irrigator body at an angle under the faucet to complete the water collection, and the gripping force required when collecting water is reduced.

As shown in Figures 1, 2, 3 and 4, the present invention provides an oral irrigator that can pour water from multiple angles. The oral irrigator includes a main casing 1 having an angular structure at the top and/or bottom ends in the height direction of the main casing 1, the angular structure being formed by connecting the main end wall 11 (the main end wall 11 may be the main ceiling wall or the main bottom wall. Note that the part indicated by the reference numeral in the figure is the main ceiling wall) and the main side wall 12 of the main casing 1, a liquid storage chamber 2 formed inside the main casing 1, and a water injection mechanism 3 having a water injection hole 31 and a hole sealing cover 32 that seals the water injection hole 31. The water injection hole 31 is opened in the angular structure and communicates with the liquid storage chamber 2. The shape of the hole sealing cover 32 is adapted to the shape of the angular structure so as to compensate for the oblique cutout area formed by the opening of the water injection hole 31. One edge of the hole sealing cover 32 is rotatably connected to the main casing 1, and the other edge is engaged with the main casing 1.

In some conventional oral irrigators, the water inlet is opened on the upper end surface of the oral irrigator body. Therefore, if the distance between the faucet and the sink is smaller than the height of the body, it is difficult for the user to place the oral irrigator body upright under the faucet to complete the water intake. In addition, the user must exert strength on the wrist. Furthermore, in some conventional oral irrigators, the water inlet is opened on the side wall of the body, and the opening direction is perpendicular to the height direction of the user. Therefore, the user must place the oral irrigator body in a horizontal position under the faucet to complete the water intake. In this case, the user must also exert strength on the wrist. Based on these conventional problems, the oral irrigator capable of injecting water from multiple angles in this invention has optimized the design of the water injection mechanism 3. That is, the main innovation of this invention lies in the opening design of the water injection hole 31. The water injection hole 31 is opened in the above-mentioned corner structure and communicates with the liquid storage chamber 2. In addition, one edge of the hole sealing cover 32 is rotatably connected to the main body casing 1, and the other edge is engaged with the main body casing 1. This design allows the user to place the oral irrigator body tilted and under the faucet to complete the process of receiving water. In addition, the user's gripping method is closer to the natural position of the wrist, so the gripping force required when receiving water is reduced.

In addition, the shape of the hole sealing cover 32 is adapted to the shape of the angular structure to compensate for the oblique cutout area formed by the opening of the water injection hole 31. As a result, there is no obvious uneven structure on the outer wall of the oral irrigator, making the overall outer contour of the oral irrigator more orderly and smooth.

Therefore, the oral irrigator of this invention, which can pour water from multiple angles, is convenient for the user to place the oral irrigator body at an angle under the faucet to complete the water collection, and the gripping force required when collecting water can be reduced.

The angles corresponding to the above angular structures can be either obtuse angles, right angles, or acute angles. In general, the angles corresponding to the angular structures are acute angles.

The angular structure is formed by connecting the main body end wall 11 and the main body side wall 12 of the main body casing 1, so that the hole sealing cover 32 includes an end cover part 321 and a side cover part 322 that are connected at an angle. One of the end cover part 321 and the side cover part 322 is rotatably provided on the main body casing 1, and the other of the end cover part 321 and the side cover part 322 is engaged with the main body casing 1. This also makes it convenient for the user to open and close the hole sealing cover 32 with one hand.

The edge of the end cover part 321 that is separated from the side cover part 322 is rotatably connected to the main body end wall 11, and the edge of the side cover part 322 that is separated from the end cover part 321 is engaged with the main body side wall 12 so that the hole sealing lid 32 has a flow-guiding function when the user receives water. Specifically, referring to FIG. 4, when using the device, the user opens the hole sealing lid 32 upward to its limit position. As a result, the end cover part 321 is provided at an angle to the horizontal plane, so that a small amount of water flow can be guided to the water inlet hole 31.

To make the overall outer contour of the oral irrigator more orderly and smooth, the end cover portion 321 is flat and is fitted to the end wall 11 of the main body when the hole sealing cover 32 seals the water inlet 31. The side cover portion 322 is curved and is fitted to the side wall 12 of the main body when the hole sealing cover 32 seals the water inlet 31.

In order to allow the user to easily grip the main body casing 1 and to open the hole sealing lid 32 more quickly, the main body casing 1 is divided into a head casing part 13 and a grip casing part 14 in the height direction. The head casing part 13 is tapered from top to bottom. The water injection mechanism 3 is provided at the upper end of the head casing part 13. When washing the mouth, the user pinches the transition connection part between the head casing part 13 and the grip casing part 14 with the thumb and index finger of the right hand. This allows the user to accurately grip the main body casing 1 in the correct position. When water needs to be received, the user first slides the thumb of the right hand upward along the side wall of the head casing part 13, and then quickly pushes the hole sealing lid 32 upward. This makes the operation of opening the lid very quick. In addition, there is no need to provide a notch or other uneven structure on the hole sealing lid 32 or the head casing part 13.

The grip casing portion 14 is tapered from top to bottom so that the user can more easily grip the main casing 1.

As shown in FIG. 5, a sealing layer 33 is provided on the inner surface of the hole sealing lid 32 to prevent water leakage. The sealing layer 33 is fitted into the opening of the water inlet 31 when the hole sealing lid 32 is attached to the main casing 1. Furthermore, an air pressure adjustment hole 331 is provided on the edge of the sealing layer 33 to prevent negative pressure from being generated in the liquid storage chamber 2 during oral cleaning. The air pressure adjustment hole 331 has a small opening size, and water or other oral cleaning fluid has "surface tension characteristics," so that even if the main casing 1 is knocked over, the water or other oral cleaning fluid in the liquid storage chamber 2 will not leak out from the air pressure adjustment hole 331.

In order to provide the oral irrigator capable of pouring water from multiple angles with a two-lid opening design, the water injection mechanism 3 is provided at the upper end of the main casing 1. The liquid storage chamber 2 penetrates downward to the bottom end of the main casing 1 so that an opening 21 of the liquid storage chamber 2 is formed at the bottom end of the main casing 1. The oral irrigator capable of pouring water from multiple angles further includes a bottom cover 4. The bottom cover 4 is removably provided at the bottom end of the main casing 1 and seals the opening 21. This arrangement makes it convenient for the user to wash the liquid storage chamber 2 to remove dirt.

As shown in Figures 6, 7, 8 and 9, in order to simplify the structure of the bottom cover 4 while realizing a removable design of the bottom cover 4, the bottom cover 4 includes a sealing engagement plate 41 that engages with the bottom end of the main casing 1. The sealing engagement plate 41 is provided with a lock unit 42 that can be returned to its original position, and a removable cover 43 that restricts the position of the lock unit 42. The lock unit 42 is used to lock the sealing engagement plate 41 to the bottom end of the main casing 1.

Furthermore, the edge of the sealing engagement plate 41 is provided with a slide groove 411 that opens in one direction to facilitate the attachment and detachment, inspection, and repair of the lock unit 42. The sealing engagement plate 41 is also provided with an attachment and detachment opening 412 that communicates with the slide groove 411. The lock unit 42 includes a locking member 421 and a position return elastic member 422. The locking member 421 is slidably provided in the slide groove 411. One side of the locking member 421 engages with the bottom end of the main casing 1, and the position return elastic member 422 is provided between the other side of the locking member 421 and the sealing end of the slide groove 411. The removable cover 43 includes a cover plate portion 431 and a blocking plate portion 432 that protrudes from the cover plate portion 431. The cover plate portion 431 is removably provided on the sealing engagement plate 41 and seals the attachment and detachment opening 412. The blocking plate portion 432 abuts against the locking member 421 to prevent the locking member 421 from coming off the slide groove 411. The position return elastic member 422 may be a compression spring. The locking member 421 has a pressing plate portion 421a and an engaging tooth portion 421b. The pressing plate portion 421a allows the user to press or push it. The engaging tooth portion 421b engages with the recessed groove of the main body casing 1. When it is desired to open the bottom cover 4, first, the pressing plate portion 421a is pressed sideways to release the locking relationship between the engaging tooth portion 421b and the main body casing 1, and then the pressing plate portion 421a is pressed downward to open the entire bottom cover 4. In addition, when it is desired to replace the position return elastic member 422, the removable cover 43 can be removed. At this time, the entire locking unit 42 can be removed from the slide groove 411.

As described above, the oral irrigator of the present invention, which can pour water from multiple angles, is convenient for the user to place the oral irrigator body tilted under the faucet to complete the water collection, and the gripping force required when collecting water is reduced. Therefore, the present invention effectively solves various shortcomings of the prior art and has a high level of industrial applicability.

The above examples are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Those familiar with the technology may supplement or modify the above examples without departing from the spirit and scope of the present invention. Therefore, any equivalent supplements or modifications completed by a person skilled in the art without departing from the spirit and technical ideas disclosed in the present invention are still included in the scope of the utility model registration claims.
