Description

Technical Field

[0001] This invention belongs to the field of oral hygiene technology, and specifically relates to a circulating rinsing device for oral care. Background Technology

[0002] With the advancement of science and technology and the development of the economy and society, oral care has gradually gained importance. For example, electric toothbrushes and water flossers are commonly used automatic oral care products. Common water flossers include the instruction manual. Figure 1 As shown, the device consists of a main body 1 and a water storage container 2 detachably connected to the main body 1. The main body 1 houses a miniature high-pressure water pump, a battery, and a control circuit board. A nozzle 12 is also located on the outside of the main body 1. The water inlet of the miniature high-pressure water pump is inserted into the water storage container 2 through a flexible hose, and the water outlet of the miniature high-pressure water pump is connected to the nozzle 12. The battery provides power, and the control circuit board controls the operation of the miniature high-pressure water pump. When operating, it draws water from the water storage container 2, pressurizes it, and sends it into the nozzle 12, where it is finally sprayed out. The user can then insert the nozzle 12 into their mouth to rinse their oral cavity. However, the nozzle 12 of this type of oral irrigator has a relatively simple structure and cannot change its spray direction. During use, the user needs to exert effort to swing the main body 1 to rinse all areas of the oral cavity, which is inconvenient. Therefore, to address the above problems, we propose a circulating rinsing device for oral care. Summary of the Invention

[0003] To overcome the problems existing in related technologies, the present invention discloses a circulating irrigation device for oral care.

[0004] To achieve the above objectives, one technical solution adopted by the present invention is:

[0005] An oral care circulating irrigation device includes a body and a water storage container detachably connected to the body, and an irrigation assembly connected to the end of a water spray pipe of the body. The irrigation assembly includes a bracket, a nozzle rotatably connected to the bracket, an elastic member disposed between the bracket and the nozzle to drive the nozzle to rotate, and a biting member slidably mounted on the bracket and pulsatorically connected to the nozzle. The bracket has a water channel communicating with the water spray pipe and the nozzle, the bracket has a bracket limiting part, and the nozzle has a nozzle limiting part.

[0006] In its natural state, the elastic member can drive the nozzle to rotate forward until the nozzle limiting part abuts against the bracket limiting part. In this state, one end of the engaging member will extend out of the bracket.

[0007] When the biting member is pushed relative to the bracket towards the side of the bracket, the biting member will cause the nozzle to rotate in the opposite direction.

[0008] Furthermore, the bracket also includes a base plate and a first side plate and a second side plate disposed on the upper side of the base plate and spaced apart. The water channel is disposed within the second side plate and the base plate. The nozzle is rotatably connected between the first side plate and the second side plate. The two ends of the elastic member are respectively connected to the first side plate and the second side plate. The engaging member is slidably assembled within the sliding space formed by the first side plate, the second side plate, the base plate, and the nozzle. The bracket limiting part is disposed on the rear side of the first side plate and the second side plate.

[0009] Furthermore, the nozzle component also includes a cylindrical portion, a curved nozzle portion connected to and communicating with the cylindrical portion on the circumferential surface of the cylindrical portion, and a first cylinder coaxially arranged with and communicating with the cylindrical portion on the end face of the cylindrical portion. The nozzle limiting portion is provided on the circumferential surface of the cylindrical portion. A first circular hole communicating with the water channel is opened on the side of the second side plate near the first side plate. The first cylinder is inserted into the first circular hole and rotates and seals with the first circular hole.

[0010] Furthermore, the bracket also includes a second cylinder located at the lower end of the base plate and communicating with the water channel, the second cylinder being detachably connected to the end of the spray pipe.

[0011] Furthermore, the cylindrical portion has a plurality of first meshing teeth on its circumferential surface, and the meshing member has a plurality of second meshing teeth on its upper side that mesh with the first meshing teeth.

[0012] The elastic element is defined as a helical spring, and the two ends of the helical spring are respectively connected to the first side plate and the cylindrical portion;

[0013] Under the action of axial elastic force, the helical spring pushes the first side plate and the cylindrical part to both sides respectively;

[0014] Furthermore, under radial torque, the helical spring will cooperate with the first side plate to cause the cylindrical portion to have a tendency to rotate in the positive direction.

[0015] Furthermore, the first side plate includes a first side plate body connected to the bottom plate, a threaded through hole opened on the first side plate body, and a limiting member threadedly connected to the threaded through hole. The limiting member has a first spring groove on the side near the second side plate, and the cylindrical part has a second spring groove on the side near the limiting member. The two ends of the helical spring are respectively locked in the first spring groove and the second spring groove.

[0016] Furthermore, the first side plate body has a limiting main groove arranged along the sliding direction of the interlocking member, the limiting main groove is connected to the threaded through hole, the limiting member has a limiting auxiliary groove that matches the limiting main groove, and the interlocking member has a limiting slide plate that is slidably assembled with the limiting main groove.

[0017] When the limiting member is assembled in the threaded through hole and the limiting auxiliary groove is not aligned with the limiting main groove, the limiting slide plate cannot completely pass through the limiting main groove;

[0018] When the limiting member is assembled in the threaded through hole and the limiting auxiliary groove is aligned with the limiting main groove, the limiting slide can completely pass through the limiting main groove.

[0019] Furthermore, the limiting member has a limiting shaft coaxially arranged with the first cylinder on the side near the cylindrical portion, and the cylindrical portion has a second insertion hole for the limiting shaft to be inserted on the side near the limiting member.

[0020] Furthermore, the nozzle component is composed of two parts assembled together.

[0021] This invention provides a circulating irrigation device for oral care. Users can rotate the tooth occlusion component and the support to guide the nozzle component, which will cause the curved nozzle to rotate and change the water spray angle. Compared with users directly adjusting by swinging the body, this adjustment method is more labor-saving, more convenient to use, and conducive to market promotion and use.

[0035] The invention will now be further described with reference to the accompanying drawings.

[0036] Reference Figure 9-10 As shown, the oral care circulating irrigation device of this embodiment includes a body 1 and a water storage container 2 detachably connected to the body 1. In this embodiment, the body 1 has a built-in miniature high-pressure water pump, a storage battery and a control circuit board. The water inlet of the miniature high-pressure water pump is connected to a hose that extends into the water storage container 2. The water outlet of the miniature high-pressure water pump is connected to a spray pipe 11. The storage battery is used to power the miniature high-pressure water pump and the control circuit board. The control circuit board integrates a control switch and a charging interface. The control switch can control the power supply of the miniature high-pressure water pump, and the charging interface is used to connect a power adapter to charge the storage battery.

[0037] A rinsing assembly 3 is connected to the end of the water spray pipe 11 of the body 1. The rinsing assembly 3 includes a bracket 31, a nozzle 32 rotatably connected to the bracket 31, an elastic member 33 disposed between the bracket 31 and the nozzle 32 to drive the nozzle 32 to rotate, and a biting member 34 slidably assembled on the bracket 31 and connected to the nozzle 32 in a transmission manner. The bracket 31 has a water channel 311 connecting the water spray pipe 11 and the nozzle 32. The bracket 31 has a bracket limiting part 312, and the nozzle 32 has a nozzle limiting part 324.

[0038] In this embodiment, the bracket 31 further includes a base plate 315 and a first side plate 313 and a second side plate 314 disposed on the upper side of the base plate 315 and spaced apart. The nozzle component 32 is rotatably connected between the first side plate 313 and the second side plate 314. The two ends of the elastic member 33 are respectively connected to the first side plate 313 and the second side plate 314. The engaging member 34 is slidably assembled within the sliding space formed by the first side plate 313, the second side plate 314, the base plate 315, and the nozzle component 32. The bracket limiting part 312 is disposed on the rear side of the first side plate 313 and the second side plate 314. The bracket 31 also includes a second cylinder 3151 disposed at the lower end of the base plate 315 and communicating with the water channel 311. The second cylinder 3151 is threadedly connected to the end of the water spray pipe 11, so that the water spray pipe 11 is connected to the water channel 311.

[0039] In this embodiment, the nozzle component 32 further includes a cylindrical portion 321, a curved nozzle portion 322 connected to and communicating with the cylindrical portion 321, and a first cylinder 323 coaxially arranged with and communicating with the end face of the cylindrical portion 321. A nozzle limiting portion 324 is provided on the circumferential surface of the cylindrical portion 321. A first circular hole 316 communicating with the water channel 311 is opened on the side of the second side plate 314 near the first side plate 313. The first cylinder 323 is inserted into the first circular hole 316 and rotates and seals with the first circular hole 316. A sealing ring can be fitted on the first cylinder 323 to enhance the sealing strength between the cylindrical portion 321 and the second side plate 314. By inserting the first cylinder 323 into the first circular hole 316, the interior of the cylindrical portion 321 can communicate with the water channel 311. Thus, the curved nozzle portion 322 is connected to the water spray pipe 11 through the cylindrical portion 321, the water channel 311, and the water spray pipe 11. The elastic element 33 is defined as a helical spring 331. The two ends of the helical spring 331 are connected to the first side plate 313 and the cylindrical part 321 respectively. Under the action of axial elastic force, the helical spring 331 pushes the first side plate 313 and the cylindrical part 321 to both sides respectively, so that the first cylinder 323 can be inserted into the first round hole 316. In this way, the insertion of the first cylinder 323 into the first round hole 316 can form a rotatable connection between the nozzle 32 and the bracket 31. Under radial torque, the helical spring 331 will cooperate with the first side plate 313 to make the cylindrical part 321 tend to rotate in the forward direction. Therefore, in the natural state, it can drive the nozzle 32 to rotate in the forward direction until the nozzle limiting part 324 abuts against the bracket limiting part 312. The cylindrical part 321 has a number of first meshing teeth 3211 on its circumferential surface, and the upper side of the biting member 34 has a number of second meshing teeth 341 that mesh with the first meshing teeth 3211, so that the biting member 34 and the nozzle 32 can be connected by transmission. Under the action of transmission connection, when the nozzle limiting part 324 is abutting against the bracket limiting part 312, one end of the biting member 34 will extend out of the bracket 31. If the biting member 34 is pushed relative to the bracket 31 towards the side closer to the bracket 31 at this time, the biting member 34 will drive the nozzle 32 to rotate in the reverse direction.

[0040] In this embodiment, when the circulating flushing device is placed vertically, the nozzle of the curved nozzle 322 will face forward.

[0041] When using this circulating rinsing device, place the water spray pipe 11 along with the rinsing component 3 into the mouth, and turn on the micro high-pressure water pump in the body 1 to pump water into the water spray pipe 11. The water entering the water spray pipe 11 will pass through the second cylinder 3151, the water channel 311, the first cylinder 323 and the cylinder section 321 in sequence, and finally be sprayed out from the curved nozzle section 322. At this time, it can be used as a regular oral irrigator. Furthermore, the user can place the biting member 34 and the bracket 31 between the upper and lower teeth, so that the nozzle of the curved mouthpiece 322 faces upward or downward. Taking the downward side as an example, when biting the biting member 34 and the bracket 31, the biting member 34 will move towards the bracket 31. In this state, it can overcome the reverse rotation of the nozzle 32 driven by the coil spring 331, that is, drive the curved mouthpiece 322 to rotate in the opposite direction. This allows adjustment of the spray angle of the curved mouthpiece 322. The size of the rotation angle can be controlled by controlling the amount of biting. For example, the nozzle of the curved mouthpiece 322 can be controlled to rotate towards the inside of the lower teeth, thus rinsing the inside of the lower teeth. Changing the spray angle of the curved mouthpiece 322 by biting is more effortless and convenient than the user directly adjusting by swinging the body 1, which is conducive to market promotion and use. It is worth mentioning that the user can frequently bite the biting member 34 and the bracket 31 to change the spray angle of the curved mouthpiece 322 cyclically, thus forming a cyclic rinsing to meet different rinsing needs.

[0042] To facilitate the assembly of the nozzle component 32 and the helical spring 331 with the bracket 31, the following design is made in this embodiment. Specifically, the first side plate 313 includes a first side plate body 3131 connected to the base plate 315, a threaded through hole 3132 opened on the first side plate body 3131, and a limiting member 3133 threadedly connected to the threaded through hole 3132. The limiting member 3133 has a first spring groove 3134 on the side near the second side plate 314, and the cylindrical part 321 has a second spring groove 3213 on the side near the limiting member 3133. The two ends of the helical spring 331 are respectively locked in the first spring groove 3134 and the second spring groove 3213. When assembling the nozzle assembly 32 and the helical spring 331 with the bracket 31, the nozzle assembly 32 is placed between the first side plate body 3131 and the second side plate 314, and the first cylinder 323 is inserted into the first circular hole 316. Then, the helical spring 331 abuts against the side of the cylinder 321 near the first side plate body 3131, and the end of the helical spring 331 near the cylinder 321 is inserted into the second spring slot 3213. After that, the limiting member 3133 can be screwed on. The retaining member 3133 is inserted into the threaded through hole 3132, causing the elastic member 33 to be pressed against the cylindrical part 321 and the retaining member 3133. When screwing in, the end of the helical spring 331 away from the cylindrical part 321 is inserted into the first spring retaining groove 3134. By inserting both ends of the helical spring 331 into the first spring retaining groove 3134 and the second spring retaining groove 3213 respectively, the cylindrical part 321 will have a tendency to rotate in the forward direction in conjunction with the retaining member 3133. After tightening, the assembly is completed. When disassembly is required, the retaining member 3133 can be disassembled by unscrewing it out of the threaded through hole 3132. It is worth mentioning that there is an internal hexagonal groove 3138 on the outer side of the retaining member 3133. The internal hexagonal groove 3138 is designed to facilitate the insertion of an internal hexagonal wrench to tighten the retaining member 3133.

[0043] To prevent the limiting member 3133 from loosening during use, the following protective design is implemented in this embodiment. Specifically, the first side plate body 3131 has a limiting main groove 3135 that is provided along the sliding direction of the engaging member 34. The limiting main groove 3135 communicates with the threaded through hole 3132. The limiting member 3133 has a limiting auxiliary groove 3136 that matches the limiting main groove 3135. The engaging member 34 has a limiting slide plate 342 that is slidably assembled with the limiting main groove 3135. When the limiting member 3133 is assembled in the threaded through hole 3132 and the limiting auxiliary groove 3136 is not aligned with the limiting main groove 3135, the limiting slide plate 342 cannot completely pass through the limiting main groove 3135. When the limiting member 3133 is assembled in the threaded through hole 3132 and the limiting auxiliary groove 3136 is aligned with the limiting main groove 3135, the limiting slide plate 342 can completely pass through the limiting main groove 3135. Based on this, during the assembly of the rinsing assembly 3, the nozzle 32 and the spiral spring 331 are first installed sequentially, and then the limiting member 3133 is tightened in place. After the limiting member 3133 is tightened in place, the limiting auxiliary groove 3136 will be aligned with the limiting main groove 3135. At this time, the nozzle 32 can be rotated in the opposite direction to the limit position, that is, the curved nozzle 322 abuts against the bracket 31. Then, the engaging member 34 is aligned with the sliding space, and the limiting slide plate 342 is aligned with the limiting main groove 3135. Then, the engaging member 34 is inserted forward. After the foremost second engaging tooth 341 abuts against one of the first engaging teeth 3211, the nozzle 32 is then inserted. Release the spring, allowing it to rotate forward under the torque of the coil spring 331. During this process, the first meshing tooth 3211 will engage with the second meshing tooth 341, thus driving the biting member 34 to slide forward and assemble into the sliding space. The corresponding limiting slide plate 342 will insert into the limiting main groove 3135, and the nozzle 32 will rotate until the nozzle limiting part 324 abuts against the bracket limiting part 312. In this state, the front end of the nozzle 32 will extend out of the sliding space, and part of the limiting slide plate 342 will be located in the limiting auxiliary groove 3136, thus limiting the limiting member 3133 and preventing it from rotating. When the rinsing assembly 3 needs to be disassembled for maintenance, the biting member 34 can be pushed backward until it is completely out of the sliding space. In this state, the limiting slide plate 342 will exit the limiting auxiliary groove 3136, and the limiting member 3133 can then be unscrewed for disassembly. When the user uses the bite member 34, the upper and lower teeth are located at both ends of the bite member 34, so the bite member 34 cannot be pushed backward into the sliding space. During the biting process, the limiting slide plate 342 will always be in the limiting auxiliary groove 3136, thus preventing the limiting member 3133 from loosening during the use of the rinsing component 3, so as to avoid the small parts of the rinsing component 3 from being loosened and swallowed by the user, which is safer.

[0044] To enhance the connection strength between the nozzle component 32 and the bracket 31, the following design is incorporated in this embodiment: Specifically, the limiting component 3133 has a limiting shaft 3137 coaxially arranged with the first cylinder 323 on the side near the cylindrical portion 321, and the cylindrical portion 321 has a second insertion hole 3212 for the limiting shaft 3137 to be inserted on the side near the limiting component 3133. After the limiting component 3133 is assembled, the limiting shaft 3137 will be inserted into the second insertion hole 3212, thereby providing axial stability to the cylindrical portion 321. Simultaneously, the coil spring 331 can be sleeved on the outside of the limiting shaft 3137 to stabilize the coil spring 331.

[0045] It is worth mentioning that the nozzle assembly 32 is composed of two parts. After the nozzle assembly 32 has been used for a period of time, it can be removed and then the nozzle assembly 32 can be separated into two parts to expose its internal space for easy cleaning.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
