Description

Technical Field

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

[0002] As society develops, people's demands for living standards are increasing, and more and more people are pursuing a higher quality of life. Therefore, water flossers are becoming increasingly popular. On one hand, the pressurized water jet from a water flosser can penetrate 50-90% of the gum line, effectively cleaning various crevices, pores, and uneven surfaces, thus ensuring oral hygiene and eliminating bad breath caused by poor oral hygiene. On the other hand, in addition to cleaning teeth and the mouth, the water flow from a water flosser also massages the gums, promoting blood circulation and enhancing the local tissue's resistance to disease.

[0003] A water flosser typically consists of a body and a detachable nozzle. The body includes a shell, a core assembly, and a water tank. The core assembly, housed within the shell, draws water from the tank and ejects it through the nozzle. To isolate the core assembly from the water tank, a core support is usually installed inside the shell. The core assembly is housed within this support and sealed at the bottom with a cap. The core support and shell are injection molded as a single unit. However, at the intersection of the core support and shell, there are sharp angles, abrupt changes in thickness, or uneven thickness. Consequently, a groove (also known as a thickness mark) appears on the outer surface of the shell corresponding to the intersection, affecting the aesthetics of the shell. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application aims to provide a housing structure for a water flosser that can solve the problem of indentation at the intersection of the core and the outer shell, and increase the aesthetics of the outer shell surface.

[0007] The outer shell has a hollow structure and has an opening at the top and an opening at the bottom;

[0008] A mechanism cover is located inside the housing, the side of which is in sealed contact with the inner surface of the housing. The mechanism cover divides the interior of the housing into an upper mechanism space for installing mechanism components and a lower water tank space for holding water.

[0009] The water flosser housing structure of this technical solution eliminates the need for a core frame inside the housing. Instead, a core cover is used inside the housing to form a sealed core space, which also separates the water tank space. This simplified housing structure makes assembly and operation easier and reduces manufacturing costs.

[0010] In one or more embodiments, the inner surface of the housing is provided with at least one first protrusion, and the first protrusion is provided with a first abutting surface on the side facing the lower opening, and the mechanism cover abuts against the first abutting surface.

[0012] In one or more embodiments, the inner surface of the housing is further provided with at least one second protrusion, and the second protrusion has a second abutting surface on the side facing the upper opening, and the upper cover abuts against the second abutting surface.

[0013] In one or more embodiments, the mechanism cover is provided with a pipe connector, one end of which is connected to the mechanism assembly via a flexible pipe, and the other end of which is connected to the water tank space via a water inlet pipe.

[0014] In one or more embodiments, a water tank cover is further included, which engages with the lower opening. The water tank cover is connected to the outer shell to seal the water tank space. A water inlet for filling the water tank space is provided on the outer shell, and the water inlet is provided with an openable and closable water inlet cover.

[0015] In one or more embodiments, the water tank cover is provided with a protruding buckle and a movable spring buckle below the sealing area, and the inner surface of the lower opening of the outer shell is provided with a plurality of buckle grooves, which correspond to and cooperate with the protruding buckle and the spring buckle, so that the water tank cover is detachably connected to the outer shell.

[0016] In one or more embodiments, a foolproof structure is further provided between the water tank cover and the outer shell.

[0017] In one or more embodiments, the outer casing is further provided with a transparent window made of a transparent material, the transparent window being used to observe the water level inside the water tank space.

[0018] In one or more embodiments, the upper opening of the housing is further provided with a decorative cover, which is located on the outside of the upper cover.

Detailed Implementation

[0027] 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.

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

[0029] This embodiment is a water flosser, including a body and a detachable nozzle 3. The body includes a housing 1 and a core assembly 2 installed inside the housing 1. The core assembly 2 includes a frame 21 and a water pump 22 and a battery 23 mounted on the frame 21. The frame 21 is also equipped with a control board 24, which has operation buttons and indicator lights. The core assembly 2 is used to draw water in and then eject a high-pressure water stream from the nozzle 3 to rinse teeth. The structure and working principle of the core assembly 2 are prior art in this field and will not be described in detail here.

[0030] In this embodiment, the housing 1 includes an outer shell 11, a mechanism cover 12, an upper cover 13, and a water tank cover 14. The outer shell 11 has a hollow, irregular cylindrical structure, and is narrower at the top and wider at the bottom. The outer shell 11 has an upper opening 111 and a lower opening 112.

[0031] The mechanism cover 12 is located inside the outer casing 11. The side of the mechanism cover 12 is sealed against the inner surface of the outer casing 11 by a sealing ring. The mechanism cover 12 divides the interior of the outer casing 11 into an upper mechanism space 101 for installing the mechanism assembly 2 and a lower water tank space 102 for holding water.

[0032] The water flosser housing 1 eliminates the design of setting the core frame inside the outer shell 11. Instead, a core cover 12 is used inside the outer shell 11 to form a sealed core space 101, which also separates the water tank space 102. The simplified structure of the outer shell 11 makes it easy to assemble and operate, and reduces manufacturing costs.

[0033] In this embodiment, in order to limit and fix the position of the movement cover 12, the inner surface of the housing 1 is provided with a plurality of first protrusions 113. The first protrusions 113 are provided with a first abutting surface on the side facing the lower opening 112, and the movement cover 12 abuts against the first abutting surface. In this way, after the movement cover 12 is inserted from the lower opening 112, it is fixed in this position after encountering the obstruction of the first protrusions 113.

[0034] To further secure the movement cover 12, the upper cover 13 is fitted with an upper opening 111. The upper cover 13 is connected to the upper end of the movement assembly 2, and the movement cover 12 is connected to the lower end of the movement assembly 2. To define the position of the upper cover 13, the inner surface of the housing 1 is also provided with at least one second protrusion 114. The second protrusion 114 has a second abutting surface on the side facing the upper opening 111, and the upper cover 13 abuts against the second abutting surface.

[0035] Furthermore, the first protrusion 113 and the second protrusion 114 can extend and connect to each other as a whole.

[0036] After assembling the movement assembly 2, the movement cover 12 is screwed onto the lower end of the frame 21 of the movement assembly 2. Then, the movement assembly 2 and the movement cover 12 are inserted through the lower opening 112, and the upper cover 13 is inserted through the upper opening 111. The upper cover 13 is then fixed to the upper end of the frame 21 of the movement assembly 2 with screws. In this way, with the first protrusion 113 and the second protrusion 114 pressing against each other, the movement assembly 2, the upper cover 13 and the movement cover 12 are fixed inside the outer casing 11.

[0037] In this embodiment, the mechanism cover 12 is provided with a pipe connector 121. The pipe connector 121 has a through hole that passes through both sides. One end of the pipe connector 121 is connected to the inlet end of the water pump 22 of the mechanism assembly 2 through a flexible pipe. The other end of the pipe connector 121 is connected to the water tank space 102 through a water inlet pipe. The outlet end of the water pump 22 of the mechanism assembly 2 is connected to the nozzle 3.

[0038] In this embodiment, the water tank cover 14 is fitted with the lower opening 112, the water tank cover 14 is connected to the outer shell 11 and a sealing ring is provided between them to seal the water tank space 102, and a water inlet 115 is provided on the outer shell 11 for filling the water tank space 102 with water, and the water inlet 115 is provided with an openable and closable water inlet cover 116.

[0039] The water tank cap 14 has a protruding buckle 141 and a movable spring buckle 142 located below the sealing part. The spring buckle 142 is located in a cavity of the water tank cap 14 that is isolated from the water tank space 102. The spring buckle 142 is provided with elastic force by a spring 143. The inner surface of the lower opening 112 of the outer shell 11 has a plurality of buckle grooves 119. The buckle grooves 119 correspond to and cooperate with the protruding buckle 141 and the spring buckle 142, so that the water tank cap 14 is detachably connected to the outer shell 11. The water tank cap 14 can be removed by pressing the spring buckle 142 to disengage it from the buckle groove 119.

[0040] A foolproof structure is also provided between the water tank cover 14 and the outer shell 11. Specifically, the foolproof structure includes a protrusion 144 on the water tank cover 14 and a groove 117 on the outer shell 11. The water tank cover 14 can only fit into the lower opening 112 when the protrusion 144 and the groove 117 are engaged.

[0041] In this embodiment, the outer shell 11 is also provided with a transparent window 118 made of transparent material, which is used to observe the water level inside the water tank space 102.

[0042] In this embodiment, the upper opening 111 of the outer shell 11 is also provided with a decorative cover 15, which is located on the outside of the upper cover 13. In addition, the upper cover 13 is also provided with a limiting structure 16 for the nozzle 3. The limiting structure 16 is prior art in this field and will not be described in detail here.
