Description

Technical Field

[0001] The utility model belongs to the technical field of oral cleaning, and particularly relates to a portable oral irrigator. Background Art

[0002] Brushing teeth is the most popular form of self-care. Brushing only cleans the surface of teeth that a toothbrush can reach. However, cleaning between teeth, especially the gingival sulcus, requires other dental hygiene products. Therefore, an oral irrigator is a supplementary tool for toothbrushes, allowing them to clean areas difficult to reach, such as between teeth and the gingival sulcus.

[0003] In existing oral irrigators, the water tank for containing cleaning liquid is often connected to the body of the oral irrigator in a fixed or detachable manner. The water tank is often designed to have a large volume, which makes it inconvenient to carry. When the water tank is designed to have a smaller volume, it can hold less cleaning liquid, resulting in the need to add cleaning liquid multiple times during use, causing inconvenience.

[0004] To address the above technical issues, existing technologies have employed a retractable water tank design to address these issues. For example, the prior art discloses a utility model patent titled "Water Tank and Water Irrigator" (Grant Announcement No. CN215306905U). Before using the water irrigator, adjacent folded sections can be moved apart to increase the volume of the receiving space, thereby accommodating more cleaning fluid. After use, the adjacent folded sections can be moved closer together to reduce the volume of the receiving space, thereby improving the portability of the water irrigator.

[0005] For example, the prior art discloses a utility model patent named a telescopic kettle and a water flosser with a telescopic kettle (authorization announcement number: CN209899636U), which can adjust the volume of the kettle to adapt to various life scenarios.

[0006] However, when the irrigator is in use, the water tank is in an expanded state. If the water tank is squeezed by external force, the storage space of the water tank will be compressed. At this time, the water tank needs to be expanded again, which may easily cause damage to the connection structure between the water tank and the body of the irrigator, affecting the normal use of the irrigator. Utility Model Content

[0007] The purpose of the present utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a portable dental irrigator. When in use, the compressed section is unfolded to increase the volume of the accommodation space, thereby accommodating more cleaning liquid. At the same time, a connecting member is installed between the body and the bottom shell. When the unfolded compressed section is subjected to an external force, the compressed section still maintains the form when unfolded and is not affected by the external force, avoiding damage to the structure at the connection between the water tank and the body of the dental irrigator. When the dental irrigator is used up, the connecting member is removed from the body and the bottom shell, and the compressed section is compressed, reducing the volume of the accommodation space, thereby improving the portability of the dental irrigator.

[0008] To solve the above-mentioned technical problems, the present utility model adopts the following technical solutions:

[0009] A portable dental irrigator, comprising a connected water tank and a body of the dental irrigator. The water tank of the dental irrigator includes a connecting end, a tube body and a bottom shell. The connecting end, the tube body and the bottom shell form an accommodation space. The tube body includes a compressed section, and the compressed section includes a folding part and a crease part provided between two folding parts. Adjacent folding parts can approach or move away from each other around the crease part to realize the compression or unfolding of the compressed section. It is characterized in that: a connecting member is detachably connected between the body and the bottom shell. When the compressed section is in the unfolded state, the connecting member is limited on the body and the bottom shell; when the compressed section is in the compressed state, the connecting member is detached from the body and the bottom shell.

[0010] Furthermore, both the body and the bottom shell are provided with a first limiting hole, and two limiting posts are provided on the inner side of the connecting member. The limiting posts are clamped in the first limiting holes, making the connection mode of the connecting member on the body and the bottom shell simple and facilitating the quick installation or disassembly of the connecting member.

[0011] Furthermore, a groove is provided at the bottom of the bottom shell, and a second limiting hole is provided on the bottom shell. The second limiting hole is located in the groove. When the connecting member is removed from the body and the bottom shell, the connecting member can be embedded in the groove. At this time, the limiting posts are clamped in the second limiting holes, making the connecting member hidden at the bottom of the bottom shell, facilitating the next use of the connecting member, avoiding the loss of the connecting member, and not affecting the appearance of the portable dental irrigator.

[0012] Furthermore, the groove includes a connected first groove section and a second groove section. The first groove section is used to match the connecting member, and the width of the second groove section is greater than the width of the first groove section. When the connecting member is embedded in the groove, there is a gap between the connecting member and the inner wall of the second groove section, facilitating the application of a force to the connecting member to take out the connecting member from the groove.

[0013] Furthermore, an installation hole is provided at the bottom of the bottom shell. The installation hole is communicated with the groove, and a bottom plate is fixed to the installation hole. The second limiting hole is provided on the bottom plate, and the bottom plate can be manufactured separately according to the position of the limiting posts on the connecting member, ensuring that the limiting posts can be clamped in the second limiting holes.

[0014] Furthermore, the bottom plate is provided with connecting columns, and the second limiting holes are arranged in the connecting columns. By increasing the depth of the second limiting holes, the length of the limiting columns can be increased, thereby improving the stability of the limiting columns in the second limiting holes.

[0015] Furthermore, a pressing part is arranged on the outer side of the connecting piece. The pressing part and the limiting column are arranged correspondingly. The pressing part is provided with anti-slip lines, which facilitates applying a force on the pressing part and can quickly snap the limiting column into the first limiting hole or the second limiting hole.

[0016] Furthermore, a head is arranged at the outer end of the limiting column. The cross-sectional area of the head is smaller than that of the limiting column, ensuring that the limiting column is snapped into the first limiting hole or the second limiting hole.

[0017] Furthermore, an arc surface is arranged between the outer side and the side surface of the connecting piece to prevent the connecting piece from scratching the user's hand.

[0018] Furthermore, a plurality of convex strips are arranged on the fuselage. The convex strips are arranged vertically to increase the strength of the fuselage.

[0019] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0020] When the present utility model is in use, the folding parts are separated from each other around the crease parts, so that the compression sections are unfolded, increasing the volume of the accommodating space, and thus accommodating more cleaning liquid. Then, a connecting piece is installed between the fuselage and the bottom shell. When the unfolded compression sections are subjected to an external force, the compression sections still maintain the unfolded state and are not affected by the external force, avoiding damage to the structure at the connection between the water tank of the oral irrigator and the fuselage. When the oral irrigator is used up, the connecting piece is removed from the fuselage and the bottom shell, and then the folding parts are brought closer to each other around the crease parts, so that the compression sections are compressed, reducing the volume of the accommodating space, and thus improving the portability of the oral irrigator.

The pipe body 3 includes a compression section, and the compression section includes a folding portion 5 and a crease portion 6 provided between two folding portions 5. Adjacent folding portions 5 can approach or move away from each other around the crease portion 6 to compress or expand the compression section. The present utility model designs the water tank of the oral irrigator to be telescopic, and this solution is prior art. For details, refer to the utility model patent with the title "Water Tank of Oral Irrigator and Oral Irrigator" (authorization announcement number: CN215306905U).

[0040] Based on the solution of the telescopic water tank of the oral irrigator, the present utility model additionally provides a connecting piece 7 made of a hard material. The connecting piece 7 can be made of plastic, is not easily deformed, and has good strength. The connecting piece 7 includes an inner side 12, an outer side 14, and a side surface 13. An arc surface 11 is provided between the outer side 14 and the side surface 13 of the connecting piece 7 to prevent the connecting piece 7 from scratching the user's hand.

[0041] Two limiting posts 9 are provided on the inner side 12 of the connecting piece 7 and are distributed vertically. According to the shape of the limiting posts 9, the present utility model provides a first limiting hole 8 on both the body 1 and the bottom shell 4.

[0042] A groove 17 is provided at the bottom of the bottom shell 4. The groove 17 includes a first groove section 18 and a second groove section 19 that are connected. The first groove section 18 is used to match the connecting piece 7, and the width of the second groove section 19 is greater than the width of the first groove section 18. When the connecting piece 7 is embedded in the groove 17, there is a gap between the connecting piece 7 and the inner wall of the second groove section 19, which is convenient for applying a force to the connecting piece 7 to take the connecting piece 7 out of the groove 17.

[0043] An installation hole is provided at the bottom of the bottom shell 4, and the installation hole is communicated with the groove 17. A bottom plate 21 is fixed in the installation hole. According to the shape of the limiting posts 9, a second limiting hole 20 is provided on the bottom plate 21 so that the second limiting hole 20 is located in the groove 17. The bottom plate 21 can be separately manufactured according to the position of the limiting posts 9 on the connecting piece 7 to ensure that the limiting posts 9 can be tightly clamped in the second limiting hole 20. The bottom plate 21 is provided with a connecting post 22, and the second limiting hole 20 extends into the connecting post 22 to increase the depth of the second limiting hole 20, thereby increasing the length of the limiting posts 9 and improving the stability of the limiting posts 9 in the second limiting hole 20.

[0044] An end head 10 is provided at the outer end of the limiting post 9, and the cross-sectional area of the end head 10 is smaller than the cross-sectional area of the limiting post 9 to ensure that the limiting post 9 is clamped into the first limiting hole 8 or the second limiting hole 20.

[0045] The present utility model designs another embodiment for the connecting member 7. A pressing portion 15 is provided on the outer side 14 of the connecting member 7.

The pressing portion 15 is provided with anti-slip lines 16, which facilitates applying a force on the pressing portion 15 and can quickly snap the limiting post 9 into the first limiting hole 8 or the second limiting hole 20.

[0046] When the present utility model is in use, the folding portion 5 is separated from each other around the crease portion 6 to expand the compression section, increasing the volume of the accommodation space, thereby accommodating more cleaning liquid. Then, the limiting post 9 of the connecting member 7 is clamped into the first limiting hole 8 of the fuselage 1 and the bottom shell 4, so that the connecting member 7 is limited between the fuselage 1 and the bottom shell 4. When an external force acts on the expanded compression section, the compression section still maintains the form when it is expanded and is not affected by the external force, avoiding damage to the structure at the connection between the water tank of the oral irrigator and the fuselage 1. When the oral irrigator is used up, the connecting member 7 is removed from the fuselage 1 and the bottom shell 4, and the connecting member 7 is inserted into the groove 17. At this time, the limiting post 9 of the connecting member 7 is clamped in the second limiting hole 20, so that the connecting member 7 is hidden at the bottom of the bottom shell 4, which is convenient for the next use of the connecting member 7 and at the same time avoids the loss of the connecting member 7 and does not affect the appearance of the portable oral irrigator. Then, the folding portion 5 is brought closer to each other around the crease portion 6 to compress the compression section, reducing the volume of the accommodation space, thereby improving the portability of the oral irrigator. The connection method of the connecting member 7 of the present utility model between the fuselage 1 and the bottom shell 4 is simple, facilitating the quick installation or disassembly of the connecting member 7.

[0047] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present utility model to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present utility model.
