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.

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

[0006] This technical solution provides a housing structure for a water flosser, including an outer shell, with a core support frame inside the outer shell. The core support frame and the outer shell form a core space for installing core components. The core space has an upper opening and a lower opening.

[0007] The movement frame has a first section near the lower opening and a second section near the upper opening. Both the first and second sections are curved thin-plate structures. The side of the first section is connected to the inner surface of the outer shell through a first connecting part, and the side of the second section is tangentially connected to the inner surface of the outer shell.

[0008] The technical effect of this solution is that the movement frame is divided into a first section and a second section. The first section is connected to the outer shell through a first connecting part. Since the direction of the intersection connection between the first connecting part and the outer shell can be changed arbitrarily, the sudden change or uneven thickness transition can be eliminated, which would cause thickness marks on the outer surface of the outer shell after injection molding. The outer surface of the outer shell is free of indentations. The second section of the movement frame is tangentially connected to the outer shell, so that the edge of the cross-section of the lower opening presents a smooth arc. This allows for better waterproofing after waterproof components such as the movement cover are installed.

[0009] In one or more embodiments, the core frame is further provided with a second connecting portion, which is connected to the inner surface of the first section, the second section and the outer shell.

[0010] In one or more embodiments, the outer shell and the movement frame are integrally molded. The outer shell and the movement frame are injection molded from plastic material.

[0011] In one or more embodiments, a movement bottom cover is further included, the movement bottom cover sealingly covering the lower opening of the movement space, the movement bottom cover being connected to the movement assembly.

[0012] In one or more embodiments, the upper opening of the movement space is provided with a cover, and the cover is connected to the movement assembly.

[0013] In one or more embodiments, the inner surface of the housing is provided with a protruding snap-fit ​​portion corresponding to the second section, the snap-fit ​​portion is not connected to the second section, and the snap-fit ​​portion is provided with a notch;

[0014] The shell structure also includes a water tank detachably disposed on the side of the outer shell. The water tank is provided with a slot, and the bottom surface of the slot is provided with a protrusion. The snap-fit ​​part is inserted into the slot and the recess cooperates with the protrusion. The outlet of the water tank is sealed to the outer shell.

[0015] In one or more embodiments, the housing is provided with a pipe connector, the lower end of which is used to connect to a water inlet pipe inserted into the water tank, and the upper end of which is used to connect to a water pump of the mechanism assembly.

[0016] 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.

[0017] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 3 As shown in the figure, 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 in the housing 1. The core assembly 2 includes a frame 21 and a water pump 22 and a battery 23 disposed in the frame 21. The frame 21 is also provided with a control board 24, which is provided with 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 the 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.

[0032] like Figures 4 to 8 As shown in the figure, in this embodiment, the housing includes an outer shell 11, a water tank 14, a bottom cover 13 of the movement mechanism and a top cover 15. The inner part of the outer shell 11 is provided with a movement mechanism support 12. The movement mechanism support 12 and the outer shell 11 form a movement mechanism space 111 for installing the movement mechanism assembly 2. The movement mechanism space 111 has an upper opening 112 and a lower opening 113.

[0033] The movement frame 12 has a first section 121 near the lower opening and a second section 122 near the upper opening 112. Both sections 121 and 122 are curved thin-plate structures. The side of the first section 121 is connected to the inner surface of the outer shell 11 via a first connecting part 123, and the side of the second section 122 is tangentially connected to the inner surface of the outer shell 11. The outer shell 11 and the movement frame 12 are integrally molded. Both the outer shell 11 and the movement frame 12 are injection molded from plastic material.

[0034] The movement frame 12 is thus divided into a first section 121 and a second section 122. The first section 121 is connected to the outer shell 11 through a first connecting part 123. Since the direction of the intersection between the first connecting part 123 and the outer shell 11 can be arbitrarily changed, the first connecting part 123 is connected to the inner surface of the outer shell 11 in a vertical manner only possible, so as to eliminate the generation of thickness marks on the outer surface of the outer shell 11 after injection molding due to sudden changes or uneven thickness transitions. The outer surface of the outer shell 11 has no indentation marks. The second section 122 of the movement frame 12 is tangentially connected to the outer shell 11, so that the edge of the cross-section of the lower opening presents a smooth arc. In this way, a better waterproof effect can be achieved after waterproof components such as the movement cover are installed.

[0035] In one or more embodiments, the movement frame 12 is further provided with a second connecting portion 124, which connects to the inner surface of the first section 121, the second section 122, and the outer shell 11. The second connection is used to enclose the area between the first section 121, the second section 122, and the outer shell 11 of the movement frame 12, forming a small space between the second section 122, the connecting portion, and the outer shell 11. This small space is prone to accumulating dirt and grime, so its volume should be minimized as much as possible. For this reason, the second section 122 is also made as short as possible, just enough to meet the sealing requirements with the movement bottom cover 13. During injection molding, this small space should not be filled with plastic.

[0036] In this embodiment, the bottom cover 13 of the movement seals and covers the lower opening of the movement space 111, and the bottom cover 13 is connected to the movement assembly 2. The bottom cover 13 is partially inserted into the lower opening, and a sealing ring 131 is provided between the two for sealing. An upper cover 15 is provided at the upper opening 112 of the movement space 111, and the upper cover 15 is connected to the movement assembly 2. In this way, the upper cover 15 and the bottom cover 13 of the movement are fixed by the movement assembly 2.

[0037] In this embodiment, the water tank 14 is detachably mounted on the side of the outer casing 11. To secure the water tank 14, the inner surface of the outer casing 11 has a protruding snap-fit ​​portion 114 corresponding to the second section 122. The snap-fit ​​portion 114 is not connected to the second section 122, and a notch 115 is provided on the snap-fit ​​portion 114. The water tank 14 has a slot 141, and a protrusion 142 is provided on the bottom surface of the slot 141. When the water tank 14 is installed on the outer casing 11, the snap-fit ​​portion 114 is inserted into the slot 141, and the notch 115 cooperates with the protrusion 142, thus sealing the outlet of the water tank 14 onto the outer casing 11.

[0038] In this embodiment, the outer casing 11 is provided with a pipe connector 116. The lower end of the pipe connector 116 is used to connect to the water inlet pipe 18 inserted into the water tank 14, and the upper end is used to connect to the water pump of the core assembly 2. The outlet of the water tank 14 is also sealed to the lower end of the pipe connector 116.

[0039] In this embodiment, the upper opening 112 of the outer casing 11 is also provided with a decorative cover 16. The decorative cover 16 is located on the outside of the upper cover 15 and is connected to the outer casing 11 and the upper cover 15 by a snap fastener or screw. The upper cover 15 is also provided with a nozzle limiting structure 17. The limiting structure 17 is used to limit the nozzle 3 to the outlet end of the water pump of the core assembly 2 and to make the nozzle 3 easy to disassemble. The limiting structure 17 is prior art in this field and will not be described in detail here.
