Description

This invention relates to the technical field of oral irrigation, and in particular to a waterproof structure for the ceiling of an intelligent sensing type oral irrigator and an intelligent sensing type oral irrigator.

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.

Conventional oral irrigators are divided into two types, normal type and intelligent sensing type, depending on the function. Intelligent sensing type oral irrigators have a distance sensor that detects the distance between the product and the user's mouth and can automatically control on/off by generating a pulse signal. This prevents the user from accidentally turning on the button, causing a stream of water to be ejected, which could injure the face or eyes.

In general, conventional intelligent sensing oral irrigators place the sensor and water inlet in different locations on the oral irrigator body. For example, the sensor is located on the ceiling of the oral irrigator body and the water inlet on the side of the oral irrigator body, and very few integrate these at one end. Furthermore, if the sensor and water inlet are located in the same location on the oral irrigator body, water leakage problems can occur, which has a significant impact on the product yield and service life.

In view of the shortcomings of the conventional technology described above, the technical problem that this invention aims to solve is to provide a waterproof ceiling structure for an intelligent sensing type oral irrigator and an intelligent sensing type oral irrigator that can integrate the water injection function area and the detection function area at the upper end of the main body casing, prevent water from penetrating into the sensor member in the sensor evacuation area when water is supplied, and allow easy attachment and detachment of the core unit and other internal mechanisms in the installation space.

In order to solve the above technical problems, the present invention provides a waterproof ceiling structure for an intelligent sensing type oral irrigator. The waterproof ceiling structure includes a body casing and a ceiling cover, the body casing has a ceiling mounting port and a body internal space communicating with the ceiling mounting port, the body internal space is divided into a mounting space and a liquid storage chamber, the casing of the body casing in the vicinity of the ceiling mounting port is tapered from top to bottom, the ceiling cover is removably attached to the ceiling mounting port, the ceiling cover includes a main casing having a sensor retreat area and a water injection retreat area, a water injection hole and a hole sealing cover that seals the water injection hole, the water injection hole is molded in the ceiling of the body casing, the water injection hole is aligned with the water injection retreat area and communicates with the liquid storage chamber, and a water injection mechanism in which a water injection seal member is provided between the opening edge of the water injection hole and the ceiling cover.

Preferably, the upper end of the main casing is further provided with an internal adhesive groove. The covering portion is also provided with a nozzle evacuation hole that allows the nozzle to be inserted. The hole wall of the nozzle evacuation hole extends downward to form a hole edge portion. The hole edge portion is engaged with the internal adhesive groove by an adhesive fixing method, and is connected in a hermetically sealed manner.

Preferably, the main body casing further includes an internal cover holder provided within the mounting space. The internal cover holder forms a liquid-tight structure with the cavity wall of the mounting space via a circumferential seal member, thereby dividing the mounting space into a liquid remaining area and a dry storage area that are distributed vertically. The body casing is provided with a button hole that communicates with the liquid remaining area. The button hole is used to provide a clearance fit for the pressing portion of the nozzle lock mechanism.

Preferably, the nozzle lock mechanism includes a nozzle locking member that is slidable relative to the inner cover holder, and an elastic position return member that returns the nozzle locking member to its position. The nozzle locking member has a button protrusion. The button protrusion is clearance-fitted into the button hole.

Preferably, the inner cover holder includes a holder body, and the holder body is provided with a nozzle insertion hole and a sliding guide groove that allows the nozzle locking member to slide back and forth. The sliding guide groove is in communication with the nozzle insertion hole and the liquid remaining area, respectively.

Preferably, the cavity wall of the mounting space is provided with a stop edge. The internal cover holder includes a holder body and a hook plate provided on the outer peripheral wall of the holder body. The hook plate abuts against the stop edge.

Preferably, the inner cover holder includes a holder body, and the holder body is provided with an air vent and a waterproof breathable film that covers the air vent. The air vent is in communication with the dry storage area.

The present invention provides an intelligent sensing type oral irrigator including a waterproof ceiling structure and a tilted ceiling water injection structure for the intelligent sensing type oral irrigator. The tilted ceiling water injection structure includes the main body casing having an angular structure at the upper end in the height direction thereof, the angular structure being formed by connecting the main body ceiling wall and the main body side wall, the liquid storage chamber molded inside the main body casing, a water injection hole and a hole sealing cover that seals the water injection hole, the water injection hole being opened in the angular structure and communicating with the liquid storage chamber, the shape of the hole sealing cover being adapted to the shape of the angular structure so as to compensate for the oblique cutout area formed by opening the water injection hole, and the water injection mechanism in which 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.

The present invention further provides an intelligent sensing type oral irrigator including a waterproof structure for the ceiling of an intelligent sensing type oral irrigator and a drop damage prevention type ceiling sensing structure. The drop damage prevention type ceiling sensing structure includes the main body casing, a cover base provided at the upper end of the main body casing, and a covering portion provided at the cover base, and includes the sensor protection cover in which a part or all of the structure in the covering portion is raised to form a sand dune-like overhang, the sand dune-like overhang protruding from the upper end of the main body casing, the sand dune-like overhang being formed by the intersection of the windward inclined side wall and the leeward inclined side wall, the ridgeline of the sand dune-like overhang being curved, and the ridgeline gradually becomes higher and then gradually lower along the extension direction compared to the height of the upper end of the main body casing, and the intelligent sensor is installed at the upper end of the main body casing and is located within the sand dune-like overhang, and the intelligent sensor is installed diagonally along the inner surface of the windward inclined side wall.

As described above, the ceiling waterproof structure of the intelligent sensing type oral irrigator and the intelligent sensing type oral irrigator in the present invention have the following beneficial effects. That is, the ceiling cover is removably attached to the ceiling mounting port of the body casing. The ceiling cover also has a sensor evacuation area and a water injection evacuation area. By arranging in this manner, the water injection function area and the detection function area can be integrated at the upper end of the main body casing, and the ceiling space of the intelligent sensing type oral irrigator can be fully utilized. In order to reliably guarantee the waterproofness between the sensor evacuation area and the water injection evacuation area, the water injection hole is aligned with the water injection evacuation area and communicates with the liquid storage chamber. In addition, a water injection seal member is provided between the opening edge of the water injection hole and the ceiling cover. By arranging in this manner, it is possible to avoid a situation in which water enters the sensor evacuation area when the user supplies water to the water injection hole, and it is ensured that the sensor member located in the sensor evacuation area is not damaged by water intrusion. Alternatively, the information collection accuracy of the sensor member located in the sensor evacuation area is guaranteed. In addition, the portion of the body casing that is closest to the ceiling mounting port tapers from top to bottom. The ceiling cover is also removably attached to the ceiling mounting port. This makes it easy to attach and detach the core unit and other internal mechanisms in the mounting space. Therefore, the ceiling waterproof structure of the intelligent sensing type oral irrigator in this invention can integrate the water injection function area and the detection function area at the top end of the main body casing. This also prevents moisture from penetrating the sensor member in the sensor evacuation area when water is being supplied, and makes it easy to attach and detach the core unit and other internal mechanisms in the mounting space.

As shown in Figures 1, 2, 3, 4 and 15, the present invention provides an intelligent sensing type oral irrigator. The intelligent sensing type oral irrigator includes a main body casing 1, a core unit 7 (the core unit 7 in Figure 3 is simplified with a rectangular pattern), a sensor unit 3 and a nozzle 4. The core unit 7 is provided in the internal space of the main body casing 1. The intelligent sensor 31 of the sensor unit 3 is provided at the upper end of the main body casing 1. And the intelligent sensor 31 is connected to the core unit 7 for communication through a data cable 33. The nozzle 4 is removably inserted at the upper end of the main body casing 1. When the user performs oral irrigation, the intelligent sensor 31 can detect in real time whether the nozzle 4 has been inserted into the user's oral cavity (the principle of intelligent detection of the intelligent sensor 31 is a conventional technology, so it will not be described in detail here). When the intelligent sensor 31 detects that the nozzle 4 has been inserted into the user's oral cavity, the intelligent sensing type oral irrigator is switched to a cleaning mode. Furthermore, when the intelligent sensor 31 detects that the nozzle 4 is not inserted into the user's oral cavity, the intelligent sensing type oral irrigator is switched to a stop mode.

The intelligent sensing type oral irrigator has a ceiling waterproof structure, a ceiling sloped water injection structure, and a fall damage prevention type ceiling sensing structure. It is particularly worth noting that the same part may belong to one or more of the ceiling waterproof structure, the ceiling sloped water injection structure, the ceiling integrated structure, and the fall damage prevention type ceiling sensing structure. For example, the main body casing 1 is part of the ceiling waterproof structure and also part of the ceiling sloped water injection structure.

First, the technical solution for the waterproof structure of the ceiling of the intelligent sensing type oral irrigator is as follows:

As shown in Figures 5, 6, 7, 8 and 9, the present invention provides a waterproof structure for the ceiling of an intelligent sensing type oral irrigator. The waterproof structure for the ceiling includes a main casing 1 and a water injection mechanism 5.

The main body casing 1 includes a body casing 11 and a ceiling cover 12. The body casing 11 has a ceiling mounting port 111 and a body internal space that communicates with the ceiling mounting port 111. The body internal space is divided into a mounting space 112 and a liquid storage chamber 113. The portion of the body casing 11 that is close to the ceiling mounting port 111 tapers from top to bottom. The ceiling cover 12 is removably attached to the ceiling mounting port 111. The ceiling cover 12 has a sensor evacuation area 121 and a water injection evacuation area 122.

The water injection mechanism 5 includes a water injection hole 51 and a hole sealing cover 52 that seals the water injection hole 51. The water injection hole 51 is molded in the ceiling of the body casing 11. The water injection hole 51 is aligned with the water injection evacuation area 122 and communicates with the liquid storage chamber 113. A water injection seal member 53 is provided between the opening edge 511 of the water injection hole 51 and the ceiling cover 12.

In the waterproof ceiling structure of the present invention, the ceiling cover 12 is removably attached to the ceiling mounting port 111 of the body casing 11. The ceiling cover 12 also has a sensor evacuation area 121 and a water injection evacuation area 122. By providing it in this way, the water injection function area and the detection function area can be integrated at the upper end of the main body casing 1, and the ceiling space of the intelligent sensing type oral irrigator can be fully utilized. In order to reliably guarantee the waterproofness between the sensor evacuation area 121 and the water injection evacuation area 122, the water injection hole 51 is aligned with the water injection evacuation area 122 and communicates with the liquid storage chamber 113. In addition, a water injection seal member 53 is provided between the opening edge 511 of the water injection hole 51 and the ceiling cover 12. By providing it in this way, it is possible to avoid a situation in which water enters the sensor evacuation area 121 when the user supplies water to the water injection hole 51, and it is ensured that the sensor member located in the sensor evacuation area 121 is not damaged by water infiltration. Alternatively, the accuracy of information collection by the sensor member located within the sensor retreat area 121 is guaranteed. In addition, the portion of the body casing 11 that is close to the ceiling mounting opening 111 tapers from top to bottom. The ceiling cover 12 is also removably attached to the ceiling mounting opening 111. This makes it easy to attach and detach the core unit 7 and other internal mechanisms within the mounting space 112.

The water injection seal member 53 may have a variety of shapes and structures. For example, the water injection seal member 53 may be flexible and elongated. When the water injection evacuation area 122 of the ceiling cover 12 is U-shaped, the water injection seal member 53 is a flexible seal strip. The flexible seal strip extends while curving along the U-shaped opening of the water injection evacuation area 122. The water injection seal member 53 and the body casing 11 can be made using a mold injection molding method that combines soft and hard materials. The water injection seal member 53 may also be manufactured from a 60-degree soft material, and a preload interference of 0.2 mm is maintained during assembly.

As shown in Figures 6, 7 and 12, a seal layer 54 is provided on the inner surface of the hole sealing cover 52 to prevent water leakage during oral cleaning. The seal layer 54 is fitted into the opening edge 511 of the water injection hole 51 when the hole sealing cover 52 is engaged with the main casing 1. The seal layer 54 and the hole sealing cover 52 can be made by a mold injection molding method that combines soft and hard materials. The seal layer 54 may also be made of a 60 degree soft material, and a preload interference of 0.2 mm is maintained during assembly.

Therefore, the waterproof ceiling structure of the intelligent sensing type oral irrigator in this invention allows the water injection function area and the detection function area to be integrated at the upper end of the main casing 1. In addition, it prevents moisture from penetrating into the sensor member in the sensor evacuation area 121 when water is being supplied, and makes it easy to attach and detach the core unit 7 and other internal mechanisms in the mounting space 112.

4, the body casing 11 is divided into a head casing part 115 and a grip casing part 116 in the height direction so that the user can easily grip the main body casing 1 and open the hole sealing lid 52 more quickly. The head casing part 115 is tapered from top to bottom. The water injection mechanism 5 is provided at the upper end of the head casing part 115. When washing the mouth, the user pinches the transition connection part between the head casing part 115 and the grip casing part 116 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 115, and then quickly pushes the hole sealing lid 52 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 52 or the head casing part 115.

9, 10, 11, 13 and 14, the upper end of the main casing 1 is provided with an external adhesive groove 131 to prevent the sensor unit 3 from being submerged. The external adhesive groove 131 may be a closed structure. The waterproof ceiling structure of the intelligent sensing type oral irrigator further includes a sensor protection cover 2 located in the sensor evacuation area 121. The sensor protection cover 2 includes a cover base 21, a covering portion provided on the cover base 21, and a skirt portion 23 provided on the cover base 21. The covering portion is used to cover the sensor unit 3. The skirt portion 23 is engaged with the external adhesive groove 131 by an adhesive fixing method and connected in a sealed manner. Furthermore, the upper end of the main casing 1 is also provided with an internal adhesive groove 132. In addition, the covering portion is provided with a nozzle evacuation hole 224 that allows the nozzle 4 to be inserted. The hole wall of the nozzle evacuation hole extends downward to form a hole edge portion 24. The hole edge 24 is engaged with the internal adhesive groove 132 in an adhesive fixing manner and is connected in a sealed manner. In some specific embodiments, the body casing 1 further includes an internal cover holder 13. The internal cover holder 13 is removably installed inside the body casing 11. The internal cover holder 13 has the external adhesive groove 131 and the internal adhesive groove 132.

6 and 7, the ceiling cover 12 and the body casing 11 are connected by hooks, so there may be a fitting gap. There may also be a fitting gap between the ceiling cover 12 and the sensor protection cover 2. Therefore, moisture and water vapor are not sealed, but the intrusion of foreign matter such as dust and particles can be blocked. The main body casing 1 further includes an internal cover holder 13 provided in the mounting space 112. The internal cover holder 13 forms a liquid-tight structure with the hollow wall of the mounting space 112 via the circumferential seal member 14, thereby dividing the mounting space 112 into a liquid remaining area and a dry storage area distributed vertically. The body casing 11 is provided with a button hole 114 that communicates with the liquid remaining area. The button hole 114 is used to fit the pressing part of the nozzle lock mechanism 6 into the gap. When the user presses the pressing part, the button hole 114 can discharge the remaining liquid in the liquid remaining area, thereby realizing a flow guide function. Therefore, a dry and hygienic environment is guaranteed inside the ceiling of the main casing 1 without the need to open a separate hole. Alternatively, the user can simply press the pressing area and then shake the main casing 1 back and forth to shake the remaining liquid in the liquid remaining area out of the main casing 1.

Furthermore, the nozzle locking mechanism 6 includes a nozzle locking member 61 that is slidable relative to the internal cover holder 13, and an elastic position return member 62 that returns the nozzle locking member 61 to its position. The nozzle locking member 61 has a button protrusion 611. The button protrusion 611 is gap-fitted into the button hole 114. By providing it in this manner, when the button protrusion 611 of the nozzle locking member 61 is pressed, the button hole 114 immediately communicates with the remaining liquid area.

To facilitate the discharge of residual liquid located at the engagement point of the nozzle 4 from the button hole 114, the inner cover holder 13 includes a holder body 133, which is provided with a nozzle insertion hole 134 and a sliding guide groove 135 that allows the nozzle locking member 61 to slide back and forth. The sliding guide groove 135 is connected to the nozzle insertion hole 134 and the residual liquid area.

As shown in Figures 8 and 11, in order to quickly position and install the internal cover holder 13, the cavity wall of the mounting space 112 is provided with an abutment edge 112a. The internal cover holder 13 also includes a holder body 133 and a hook plate 136 provided on the outer peripheral wall of the holder body 133. The hook plate 136 abuts against the abutment edge 112a.

As shown in Figures 7 and 11, since the inside of the core unit 7 may generate heat, the internal cover holder 13 includes a holder body 133, which is provided with an air vent 137 and a waterproof breathable film 138 that covers the air vent 137. The air vent 137 is connected to the dry storage area. By providing it in this way, it is possible to eliminate the effect on liquid tightness of the gas expansion phenomenon caused by heat generation from the core unit 7, and achieve a balance between pressure and temperature.

Next, the technical solution for the inclined ceiling water injection structure of the intelligent sensing type oral irrigator is as follows:

The inclined ceiling water injection structure includes the main casing 1, the liquid storage chamber 113, and the water injection mechanism 5.

The main body casing 1 has a corner structure at the top end in the height direction. The corner structure is formed by connecting the main body ceiling wall and the main body side wall of the main body casing 1.

The liquid storage chamber 113 is molded inside the main casing 1.

The water injection mechanism 5 includes a water injection hole 51 and a hole sealing lid 52 that seals the water injection hole 51. The water injection hole 51 is opened in the angular structure and communicates with the liquid storage chamber 113. The shape of the hole sealing lid 52 is adapted to the shape of the angular structure so as to compensate for the oblique cutout area formed by opening the water injection hole 51. One edge of the hole sealing lid 52 is rotatably connected to the main casing 1, and the other edge is engaged with the main casing 1.

The angular structure is formed by connecting the ceiling wall (i.e., the ceiling cover 12) and the side wall (i.e., the body casing 11) of the main casing 1. The main innovation of the inclined ceiling water injection structure is the opening design of the water injection hole 51. That is, the water injection hole 51 is opened in the angular structure and communicates with the liquid storage chamber 113. One edge of the hole sealing cover 52 is rotatably connected to the main casing 1, and the other edge is engaged with the main casing 1. This design allows the user to place the oral irrigator body under the faucet in an inclined state to complete the water intake. In addition, the user's gripping method is closer to the natural position of the wrist, so the gripping force when receiving water is reduced.

Finally, the technical solution for the ceiling sensing structure of the intelligent sensing type oral irrigator to prevent damage from falling is as follows:

The fall damage prevention ceiling sensing structure includes the main body casing 1, the sensor protection cover 2, and the sensor unit 3.

The sensor protection cover 2 includes a cover base 21 provided at the upper end of the main body casing 1, and a covering portion provided on the cover base 21. Some or all of the structures in the covering portion are raised to form a sand dune-shaped overhang 22. The sand dune-shaped overhang 22 protrudes from the upper end of the main body casing 1. The sand dune-shaped overhang 22 is formed by the intersection of a windward inclined sidewall 221 and a leeward inclined sidewall 222. The ridgeline 223 of the sand dune-shaped overhang 22 is curved. Compared to the height of the upper end of the main body casing 1, the ridgeline 223 gradually becomes higher and then gradually becomes lower along its extension direction.

The intelligent sensor 31 of the sensor unit 3 is installed at the upper end of the main casing 1 and is located within the dune-like overhang 22. The intelligent sensor 31 is installed obliquely along the inner surface of the windward inclined side wall 221.

In the fall damage prevention ceiling sensing structure of the present invention, the intelligent sensor 31 (e.g., distance sensor) is installed at a protruding position at the top end of the main casing 1, thereby ensuring the accuracy of the signal detection of the intelligent sensor 31. The main innovations of the present invention are as follows. First, the sand dune-shaped protrusion 22 protrudes from the top end of the main casing 1, and the intelligent sensor 31 of the sensor unit 3 is installed at the top end of the main casing 1 and located within the sand dune-shaped protrusion 22. This makes it possible to avoid the intelligent sensor 31 being interfered with during the signal collection process. Second, the sand dune-shaped protrusion 22 is formed by the intersection of the windward inclined side wall 221 and the leeward inclined side wall 222. In addition, the ridge 223 of the sand dune-shaped protrusion 22 is curved. This allows the range of the protection area of the intelligent sensor 31 to be expanded. In addition, the ridge 223 gradually becomes higher and then gradually lower along its extension direction compared to the height of the top end of the main casing 1. In addition, the intelligent sensor 31 is installed diagonally along the inner surface of the windward inclined side wall 221. In this way, by applying the "mechanical principle of roof support", it is possible to effectively disperse the impact load caused by a fall and to diffuse the impact energy received. In other words, it is possible to strengthen the impact resistance of the sensor protection cover 2 and provide better protection.

Specifically, referring to FIG. 15, the sensor unit 3 further includes a vibration-damping member 32 to further protect the intelligent sensor 31. The vibration-damping member 32 is sandwiched between the windward inclined sidewall 221 and the intelligent sensor 31. The vibration-damping member 32 can be made of an elastic material such as silicone or rubber. To more completely protect the intelligent sensor 31, the vibration-damping member 32 is in the form of a cover to enclose the intelligent sensor 31. Furthermore, by combining FIG. 7 and FIG. 12, the vibration-damping member 32 has an oblique support surface 321 to further reduce damage to the intelligent sensor 31 due to impact force. The oblique support surface 321 is in close contact with the windward inclined sidewall 221.

As described above, the waterproof ceiling structure of the intelligent sensing type oral irrigator and the intelligent sensing type oral irrigator of this invention allow the water injection function area and the detection function area to be integrated at the upper end of the main casing. In addition, the situation in which moisture penetrates into the sensor member in the sensor evacuation area when water is supplied is avoided, and the core unit and other internal mechanisms in the mounting space can be easily attached and detached. Therefore, this invention effectively eliminates various shortcomings in 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.
