Description

Technical Field

[0001] This application belongs to the field of oral irrigator technology and relates to a waterproof structure for the charging port of an oral irrigator. Background Technology

[0002] A water flosser is a highly efficient oral hygiene tool that uses high-pressure pulsed water to precisely rinse areas that are difficult to reach with a toothbrush, such as between teeth and in the gingival sulcus, effectively removing food debris and plaque. Its advantages lie in its gentle yet deep cleaning, making it particularly suitable for orthodontic patients, periodontitis patients, and dental implant users. Clinical studies have shown that daily use of a water flosser can reduce gum bleeding rates, making it an ideal alternative or supplement to traditional dental floss.

[0003] Existing water flossers use a waterproof plug to waterproof the charging port, but they do not have a waterproof structure designed inside the charging port. Water can easily enter the water flosser from the charging port at the bottom, wetting the charging port and causing damage to the water flosser, thus affecting its use. Utility Model Content

[0026] 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.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] This embodiment discloses a waterproof structure for the charging port of a water flosser, which waterproofs the charging terminal 1203 of the charging interface provided on the water flosser body 1. Figures 1-5 As shown, it includes: a waterproof body 2, which includes a waterproof skirt 21 and an inner plug 22. The waterproof skirt 21 has a positioning boss 2101. The water flosser body 1 has a positioning groove 1102 corresponding to the positioning boss 2101. When the positioning boss 2101 is inserted into the positioning groove 1102, the waterproof body 2 can pivotally cover or expose the charging terminal 1203 with the positioning boss 2101 as the axis.

[0029] The inner plug 22 has a protruding tongue on its outside. The protruding tongue is used to form an interference seal when the waterproof component body 2 covers the charging terminal 1203. The inner plug 22 has a cavity 2203 inside. The inner plug 22 is fitted onto the outside of the charging terminal 1203 through the cavity 2203.

[0030] It should be noted that the charging interface is used to connect the data cable for charging, and the charging terminal 1203 refers to the conductive metal plate inside the charging interface.

[0031] It should be noted that the positioning boss 2101 is an arc-shaped column, and correspondingly, the positioning groove 1102 is a groove that matches the positioning boss 2101. After the two are fixed, they have ideal connection stability, and when the deformation of the waterproof component body 2 is controlled, the position of the waterproof component body 2 relative to the water flosser body 1 can be maintained without change. That is, the positioning boss 2101, as a fixed area during rotation, can provide an ideal fixing effect and avoid repeated control of the positioning boss 2101 rotation, which could cause it to detach from the water flosser body 1.

[0032] It should be noted that part of the inner plug 22 can be inserted into the charging interface, so that the charging terminal 1203 is embedded in the cavity 2203. At this time, the protrusion on the outside of the inner plug 22 forms an interference seal with the charging interface and the water flosser body 1, which serves as a waterproof function.

[0033] The cavity 2203 of the waterproof component body 2 is fitted over the outside of the charging terminal 1203 to achieve a waterproof effect inside the charging interface, preventing water from entering the water flosser from the charging port at the bottom of the water flosser, wetting the charging interface, causing damage to the water flosser and affecting its use.

[0034] like Figure 5 As shown, the positioning boss 2101 is located on one side of the waterproof skirt 21, while the other side remains in a smooth state. The positioning boss 2101 has a groove structure in its circumference. The groove structure is used to deform when the waterproof component body 2 pivots around the positioning boss 2101.

[0035] It should be noted that during use, the other side of the waterproof skirt 21 that remains in the bare state can be controlled to rotate around the positioning boss 2101. During this process, the groove structure deforms before other parts of the waterproof body 2.

[0036] like Figures 3-5 As shown, when the waterproof component body 2 pivots around the positioning boss 2101, the end of it away from the positioning boss 2101 has a closed position for inserting into the charging interface and an open position for disengaging from the charging interface.

[0037] like Figure 3 and Figure 5 As shown, the positioning boss 2101 is glued to the positioning groove 1102, and / or the positioning boss 2101 is fixed to the positioning groove 1102 by fixing screws.

[0038] like Figure 5 As shown, the cavity 2203 has at least one protruding rib 2204 inside, which is used to increase the friction between the inner plug 22 and the charging terminal 1203.

[0039] like Figures 2-4 As shown, the water flosser body 1 includes a water flosser shell 11 and a bottom cover 12. The bottom cover 12 is embedded inside the water flosser shell 11. The charging terminal 1203 is located on the bottom cover 12. The bottom cover 12 is equipped with a charging female connector 1201 to match the charging terminal 1203. The charging female connector 1201 is used to limit the charging terminal 1203.

[0040] It should be noted that placing the charging female socket 1201 on the bottom cover 12 can extend the length of the inner plug 22 of the waterproof component body 2, so as to set different specifications of protrusions to form a multi-layer waterproof structure. At the same time, it will not affect the feel of the waterproof component body 2 when opening and closing.

[0041] like Figure 3 As shown, the charging female socket 1201 is provided with a sealing ring 1202 in the circumferential direction. When the bottom cover 12 is embedded in the water flosser housing 11, the sealing ring 1202 is used to form a circumferential seal of the charging female socket 1201.

[0042] like Figure 2 and Figure 3 As shown, the water flosser housing 11 has a charging port 1101 corresponding to the charging terminal 1203. The positioning groove 1102 is located on one side of the charging port 1101, and the other side of the charging port 1101 is a bare plate. The depth of the charging port 1101 is greater than or equal to the height of the waterproof component body 2. After the waterproof component body 2 is radially pressed into the charging port 1101, its outer surface is flush with or lower than the water flosser body 1.

[0043] like Figure 4 and Figure 5 As shown, the tongue includes a first tongue 2201 and a second tongue 2202. The cross-sectional height of the first tongue 2201 is greater than the cross-sectional height of the second tongue 2202, and the first tongue 2201 and the second tongue 2202 have a radial distance to form a stepped seal with discontinuous contact.

[0044] like Figure 2 and Figure 4 As shown, when the waterproof component body 2 covers the charging interface, the first protrusion 2201 forms an interference seal with the charging interface, and the second protrusion 2202 forms an interference seal with the water flosser body 1.

[0045] It should be noted that the first protrusion 2201 is inserted into the charging interface along with the inner plug 22, and forms an interference seal with the inner wall of the charging interface. The second protrusion 2202 abuts against the charging female seat 1201 of the bottom cover 12. At the same time, the second protrusion 2202 has an abutting relationship with the opening end of the charging interface, which can reduce the deformation space of the second protrusion 2202, making the space filling tighter and improving the sealing performance.

[0046] Working principle: The cavity 2203 of the waterproof component body 2 is sleeved on the outside of the charging terminal 1203 to achieve the waterproof effect inside the charging interface, preventing water from entering the water flosser from the charging port at the bottom of the water flosser, wetting the charging interface, causing damage to the water flosser and affecting its use.

[0047] 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.
