Description

Technical Field

[0001] This application belongs to the field of oral irrigator technology and relates to an oral irrigator housing. Background Technology

[0002] As an oral hygiene device, a water flosser typically requires a breathable membrane (or waterproof breathable membrane) inside its casing to balance the air pressure inside and outside the casing. However, in existing technologies, the breathable membrane tends to accumulate water after prolonged use, leading to breathability failure. Traditional water flosser casings often have the breathable membrane directly attached to the casing surface or within a shallow recess, failing to consider the issues of water spray or residual water accumulation after cleaning. The inability to effectively channel liquid can cause it to stagnate around the breathable membrane, easily clogging the micropores, leading to the failure of the air pressure balancing function, and even causing problems such as membrane deformation due to moisture and bacterial growth.

[0003] Therefore, how to provide a water flosser housing that prevents liquid from accumulating around the breathable membrane through closed-loop circulation of hot air has become an urgent technical problem to be solved. Utility Model Content

[0004] To overcome the problems existing in the related technology, this application aims to provide a water flosser housing that can prevent liquid from accumulating around the breathable membrane.

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

[0006] This technical solution provides a water flosser housing for a breathable and waterproof membrane for the water flosser body, comprising: an outer shell, a fixing plate at one end of the outer shell near the nozzle of the water flosser body, a through opening on one side of the fixing plate, and the other side extending away from the opening and bending to form a cavity, a boss inside the cavity, a through vent hole on the boss, and a coaxial through hole corresponding to the vent hole in the breathable membrane;

[0007] The protrusion extends toward the opening to accommodate expansion holes adapted to the breathable membrane inside the cavity, forming a height difference between the breathable membrane and the bottom wall of the cavity.

[0008] This technical solution uses an outward-protruding boss design to form a controllable height difference. The boss has vent holes and a breathable membrane is attached to it, which can realize the physical isolation between liquid flow and the breathable membrane. This can effectively prevent liquid from accumulating around the breathable membrane, simplify the manufacturing process, ensure breathability, and take into account the strength and aesthetics of the shell structure.

[0009] The present invention is further configured such that the fixing plate and the outer shell are integrally formed.

[0010] The present invention is further configured such that the fixing plate and the outer shell are detachably connected, and the fixing plate is fixed to the end of the outer shell near the nozzle by a buckle or thread.

[0011] The present invention is further configured such that the diameter of the opening is smaller than the inner diameter of the outer shell, and the central axis of the opening is coaxial with the water outlet channel of the nozzle.

[0012] The present invention is further configured such that, after the outer shell is installed, a ventilation chamber is formed between the cavity and the main body of the oral irrigator, and the ventilation chamber is connected to the inner cavity of the shell through a vent hole.

[0013] The present invention is further configured such that the boss is a column structure with an arc-shaped guide surface on the top, and the side near the opening is fixedly connected to the fixing plate.

[0014] The present invention is further configured such that the boss is a stepped cylindrical structure.

[0015] The present invention is further configured such that the cross-section of the boss in the vertical direction is a semi-circular structure or a cuboid structure.

[0016] The present invention is further configured such that the expansion hole is formed in the reserved cavity at the bottom of the boss, and the breathable membrane is fixed inside the expansion hole.

[0017] The present invention is further configured such that the inner diameter of the expansion hole gradually increases from one end near the vent hole to the other end.

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.

[0028] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0029] This embodiment discloses a water flosser housing, in which the breathable membrane 11 of the water flosser body 1 is waterproofed, such as... Figures 1-6 As shown, it includes: a shell 2, a fixing plate 21 at one end of the shell 2 near the nozzle of the water flosser body 1, a through opening 22 on one side of the fixing plate 2, and the other side extending away from the opening 22 and bending to form a cavity 23, a boss 24 inside the cavity 23, a through vent hole 25 on the boss 24, and a coaxial through hole corresponding to the vent hole 25 on the vent membrane 11.

[0030] The boss 24 extends toward the opening 22 to provide an expansion hole 26 that is compatible with the breathable membrane 11 inside the cavity 23, forming a height difference between the breathable membrane 11 and the bottom wall of the cavity 23.

[0031] It should be noted that the outward protrusion of the boss 24 creates a controllable height difference. The boss 24 has ventilation holes 25 and a breathable membrane 11 is attached to it, which can achieve physical isolation between liquid flow and breathable membrane 11. This can effectively prevent liquid from accumulating around the breathable membrane, simplify the manufacturing process, and ensure breathability.

[0032] like Figure 4 and Figure 6 As shown, the fixing plate 21 and the outer shell 2 are integrally formed, which can simplify the manufacturing process.

[0033] like Figures 1-6 As shown, the fixing plate 21 is detachably connected to the outer shell 2. The fixing plate 21 is fixed to the end of the outer shell 2 near the nozzle by a snap or thread, which makes it easy to install the fixing plate 21 onto the outer shell 2.

[0034] like Figures 3-6 As shown, the diameter of the opening 22 is smaller than the inner diameter of the outer shell 1, and the central axis of the opening is coaxial with the water outlet channel of the nozzle.

[0035] It should be noted that the housing is snapped onto the outside of the water flosser body 1. After installation, the nozzle of the water flosser body 1 extends out from the opening.

[0036] like Figure 1 and Figure 3 As shown, after the outer shell 2 is installed, a ventilation chamber is formed between the cavity 23 and the main body 1 of the oral irrigator. The ventilation chamber is connected to the inner cavity of the outer shell 2 through the vent hole 25.

[0037] like Figure 2 and Figures 4-6 As shown, the boss 24 is a cylindrical structure with an arc-shaped guide surface on the top, and its side near the opening 22 is fixedly connected to the fixing plate 21. It should be noted that the arc-shaped guide surface can guide water to slide down when it comes into contact with the water, thus preventing water accumulation.

[0038] like Figures 1-6 As shown, boss 24 is a stepped cylindrical structure.

[0039] like Figures 1-6 As shown, the cross-section of the boss 24 in the vertical direction is a semi-circular structure or a cuboid structure.

[0040] like Figure 6 As shown, the expansion hole 26 is formed in the reserved cavity at the bottom of the boss 24, and the breathable membrane 11 is fixed inside the expansion hole 26.

[0041] like Figure 5 and Figure 6 As shown, the inner diameter of the expansion hole 26 gradually increases from one end near the vent hole 25 to the other end.

[0042] Working principle: The protruding boss 24 creates a controllable height difference. The boss 24 has ventilation holes 25 and a breathable membrane 11 is attached to it. This can achieve physical isolation between liquid flow and the breathable membrane 11, which can effectively prevent liquid from accumulating around the breathable membrane, simplify the manufacturing process, and ensure breathability.
