Description

Technical Field

[0001] This application belongs to the field of oral irrigator technology and relates to a bottom cover sealing structure for an oral irrigator. Background Technology

[0002] With the increasing demand for oral care, water flossers are widely used due to their efficient cleaning capabilities. The bottom cover of a water flosser, as a key sealing component, directly affects the product's waterproof performance and lifespan. Traditional bottom covers often use flat silicone gaskets or threaded tightening structures to achieve a seal. However, after prolonged pressure, especially in environments where the bottom cover needs frequent opening and closing, the sealing ring is prone to deformation, leading to seal failure. Furthermore, the threaded grooves of threaded structures easily accumulate dirt and breed bacteria.

[0003] Therefore, how to provide a sealing structure for the bottom cover of a water flosser that ensures a good seal while making the bottom cover easy to disassemble has become an urgent technical problem to be solved. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application aims to provide a bottom cover sealing structure for a water flosser that can ensure a sealing effect while making the bottom cover easy to disassemble.

[0005] This application is achieved through the following technical solution.

[0006] This technical solution provides a bottom cover sealing structure for a water flosser, used to seal the connection gap between the water flosser body and the bottom cover, including:

[0007] A sealing ring, comprising a main sealing strip and a sealing rib, wherein the sealing rib is an arc-shaped structure protruding away from the main sealing strip;

[0008] The bottom cover has an annular groove for installing the main sealing strip on its outer periphery, and the main sealing strip is fixed in the groove with an interference fit.

[0009] When the sealing rib is inserted into the body of the water flosser along with the bottom cover, it forms an adaptive sealing contact by swinging; when it is removed, it swings in the opposite direction to avoid unidirectional wear.

[0010] This technical solution uses arc-shaped raised sealing ribs to ensure a seal between the water flosser body and the bottom cover. When the bottom cover is inserted into the water flosser body, the sealing ribs swing in opposite directions to form an adaptive sealing contact. When removed, the sealing ribs swing in the opposite direction to avoid unidirectional wear. The bottom cover has a mating groove to accommodate the main sealing strip of the sealing ring, which can maintain the connection stability between the sealing ring and the bottom cover.

[0011] The present invention is further configured such that the sealing rib is connected to the main sealing strip through a connecting part, and the outer surface of the connecting part is curved.

[0012] The present invention is further configured such that the outer surface of the connecting part is a raised curved surface, which is used to improve the strength of the sealing rib structure.

[0013] The present invention is further configured such that the outer surface of the connecting part is a concave curved surface, which is used to promote the swinging of the sealing rib.

[0014] The present invention is further configured such that a reserved groove is provided at the first end of the bottom cover, a hook is provided inside the reserved groove, and a slot is provided on the body of the oral irrigator corresponding to the hook;

[0015] The second end of the bottom cover has two symmetrical reserved slots to form a locking block. The outer side of the locking block is provided with a protruding rib, and the body of the oral irrigator is provided with a groove corresponding to the protruding rib.

[0016] When the bottom cover is closed, the hook and the rib respectively engage with the slot and groove inside the body of the water flosser.

[0017] The present invention is further provided that the water flosser body is provided with a limiting block, which is used to limit the circumferential movement of the hook.

[0018] The present invention is further configured such that the oral irrigator body has a mounting cavity, and the bottom cover is fastened to the inside of the mounting cavity.

[0019] The present invention is further configured such that the card slot is a flat surface near the bottom wall of the water flosser body, which is used to cooperate with the hook to form a locking engagement.

[0020] The present invention is further provided that the second end of the bottom cover is provided with an opening flange, the opening flange being used to open the bottom cover.

[0021] The present invention is further configured such that the height of the main sealing strip is lower than or equal to the height of the mating groove, so as to prevent the inner wall of the water flosser body from squeezing the main sealing strip.

[0031] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] This embodiment discloses a bottom cover sealing structure for a water flosser, used to seal the connection gap between the water flosser body 1 and the bottom cover 2, such as... Figures 1-6 As shown, it includes:

[0034] The sealing ring 22 includes a main sealing strip 2201 and a sealing rib 2202. The sealing rib 2202 is an arc-shaped structure that protrudes away from the main sealing strip 2201. The width of the sealing rib 2202 is smaller than the width of the main sealing strip 2201.

[0035] The bottom cover 2 has an annular groove 21 for installing the main sealing strip 2201 on its outer periphery. The main sealing strip 2201 is fixed in the groove 21 with an interference fit.

[0036] When the sealing rib 2202 is inserted into the body 1 of the flosser along with the bottom cover 2, it forms an adaptive sealing contact by swinging; when it is removed, it swings in the opposite direction to avoid unidirectional wear.

[0037] It should be noted that the main sealing strip 2201 is a strip structure adapted to the mating groove 21 of the bottom cover 2. It can be embedded in the groove to stabilize the position of the sealing ring 22. The sealing rib 2202 is used to achieve sealing and can be provided with two sides of different materials so that the sealing surface, that is, the side facing the opening of the bottom cover 2, can contact the oral irrigator body 1 to achieve sealing. When the bottom cover 2 is disassembled, the other side opposite to the sealing surface is made of a smoother material to reduce friction and facilitate the removal of the bottom cover 2. The surface areas of the sealing surface and the other side can be different.

[0038] It should be noted that the sealing rib 2202 needs to be able to swing during the installation and removal of the bottom cover 2, so as to achieve self-adaptive sealing between the sealing ring 22 and the water flosser body 1, and avoid the problem of O-rings always contacting only one side of the contacting object, which is prone to damage, thus avoiding unidirectional wear. When the bottom cover 2 is installed and removed, the sealing rib 2202 can also swing to reduce the contact surface with the water flosser body 1, so as to facilitate disassembly.

[0039] The arc-shaped protruding sealing rib 2202 not only satisfies the sealing between the water flosser body 1 and the bottom cover 2, but also forms an adaptive sealing contact when the bottom cover 2 is inserted into the water flosser body 1 by swinging in the opposite direction. When removed, the sealing rib 2202 swings in the opposite direction to avoid unidirectional wear. The bottom cover 2 has a main sealing strip 2201 fixed inside the mating groove 21, which can maintain the connection stability between the sealing ring 22 and the bottom cover 2.

[0040] like Figure 5 As shown, the sealing rib 2202 is connected to the main sealing strip 2201 through the connecting part 2203, and the outer surface of the connecting part 2203 is curved.

[0041] like Figures 1-2 and Figure 5 As shown, the outer surface of the connecting part 2203 is a raised curved surface, which is used to improve the structural strength of the sealing rib 2202.

[0042] like Figures 1-2 and Figure 5 As shown, the outer surface of the connecting part 2203 is a concave curved surface, which is used to promote the swing of the sealing rib 2202.

[0043] It should be noted that the connecting part 2203 allows the sealing rib 2202 to swing around it, increasing the strength of the connecting part 2203 and effectively extending the service life of the sealing ring 22. Furthermore, different structures of the connecting part 2203 can also affect the swing amplitude of the sealing rib 2202. For example, when the connecting part 2203 is a raised structure on the convex side of an arc-shaped, approximately meniscus structure, the swing amplitude of the sealing rib 2202 is small, but the structural strength is high; when the connecting part 2203 is a concave structure on the concave side of an arc-shaped, approximately meniscus structure, the swing amplitude of the sealing rib 2202 is large, but the structural strength is low.

[0044] like Figures 2-4 and Figure 6 As shown, a reserved groove 23 is provided at the first end of the bottom cover 2, and a hook 24 is provided inside the reserved groove 23. The water flosser body 1 is provided with a slot 13 corresponding to the hook 24.

[0045] The second end of the bottom cover 2 has two symmetrical reserved slots 23 to form a locking block 25. The outer side of the locking block 25 is provided with a protruding rib 2501, and the body of the water flosser 1 is provided with a groove 14 corresponding to the protruding rib 2501.

[0046] When the bottom cover 2 is closed, the hook 24 and the rib 2501 are respectively engaged in the slot 13 and groove 14 of the water flosser body 1.

[0047] It should be noted that the bottom cover 2 is fixed in position by hook 24 and protruding rib 2501, and the hook 24 and the locking block 25 with protruding rib 2501 are elastic so that they can deform during the installation and disassembly of the bottom cover 2 to assist in the installation.

[0048] like Figure 3 and Figure 6 As shown, the water flosser body 1 is also provided with a limiting block 12, which is used to limit the circumferential movement of the hook 24.

[0049] like Figure 3 As shown, the water flosser body 1 has a mounting cavity 11, and the bottom cover 2 is fastened to the inside of the mounting cavity 11.

[0050] like Figure 6 As shown, the slot 13 is flat against the bottom wall of the water flosser body 1, which is used to engage with the hook 24. It should be noted that the other side walls of the slot 13 have arc-shaped guide surfaces to facilitate the disengagement of the hook 24 from the slot 13.

[0051] like Figures 1-4 As shown, the second end of the bottom cover 2 is provided with an opening flange 26, which is used to open the bottom cover 2.

[0052] like Figure 1 and Figure 2As shown, the height of the main sealing strip 2201 is lower than or equal to the height of the mating groove 21 to prevent the inner wall of the water flosser body 1 from squeezing the main sealing strip 2201. It should be noted that the height of the main sealing strip 2201 can also be higher than the height of the mating groove 21, so as to cooperate with the sealing rib 2202 to form a seal between the water flosser body 1 and the bottom cover 2.

[0053] Working principle: The arc-shaped convex sealing rib 2202 not only ensures the seal between the water flosser body 1 and the bottom cover 2, but also allows the sealing rib 2202 to swing in the opposite direction of insertion when the bottom cover 2 is inserted into the water flosser body 1, forming an adaptive sealing contact. When removed, the sealing rib 2202 swings in the opposite direction of insertion to avoid unidirectional wear. The bottom cover 2 has a main sealing strip 2201 fixed inside the mating groove 21, which can maintain the connection stability between the sealing ring 22 and the bottom cover 2.

[0054] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
