Description

Technical Field

[0001] This application belongs to the field of oral irrigator technology and relates to an oral irrigator with a detachable water tank. Background Technology

[0002] A water flosser is an auxiliary medical device for cleaning the oral cavity. It uses the impact force generated by high-pressure water or air to clean the blind spots between teeth and gums, including hard-to-reach areas such as between teeth, periodontal pockets, and under the gums, in order to remove plaque and food debris.

[0003] As people place increasing importance on oral care, water flossers have become widely popular due to their ability to effectively clean between teeth and along the gum line. Traditional water flossers typically use a snap-fit ​​connection to attach the water tank to the device body, but this snap-fit ​​structure is prone to trapping dirt and grime and is inconvenient to clean. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application aims to provide a water flosser with a removable water tank, which can facilitate the removal of the water tank and reduce the difficulty of cleaning.

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

[0006] This technical solution provides a water flosser with a detachable water tank. The water flosser has a first direction, which is perpendicular to the height direction of the water flosser. It includes:

[0007] Water flosser body;

[0008] A water tank is connected to the body of the oral irrigator. The water tank includes a support part and a water storage part. The contact surface between the water storage part and the body of the oral irrigator is a curved surface, and the curved surface has a height difference in a first direction.

[0009] The support section and water storage section are respectively equipped with two magnetic suction sections of the water flosser body, which are provided with a second permanent magnet and a first permanent magnet. The first permanent magnet and the second permanent magnet are used to restrict the movement of the water flosser body.

[0010] This technical solution restricts the movement of the water flosser body by using the curved surface of the water tank. The first and second permanent magnets work together with the magnetic attraction part of the water flosser body to form a magnetic attraction structure, which, together with the curved surface structure of the water tank, restricts the movement of the body.

[0011] The present invention is further configured such that the curved surface includes a third stop surface and a first stop surface and a second stop surface symmetrically arranged;

[0012] The first stop surface and the second stop surface, as well as the second stop surface and the third stop surface, are connected by a transition surface.

[0013] The present invention is further configured such that the first stop surface and the third stop surface are both planar and are arranged perpendicular to the first direction, and the second stop surface is a smooth single curved surface.

[0014] The present invention is further configured such that the first stop surface is provided with a mounting groove for mounting the first permanent magnet, the first permanent magnet is embedded in the mounting groove and covered by an openable and closable cover.

[0015] The present invention is further configured such that the support part has a water storage cavity, and the second permanent magnet is disposed on the side of the support part near the body of the oral irrigator.

[0016] The present invention is further configured such that the water inlet of the supporting part and the water inlet of the water flosser body are provided with a water inlet, and the water inlet protrudes from the upper surface of the supporting part.

[0017] The present invention is further configured such that the side of the water-retaining part of the water flosser body is a raised curved surface structure, and a protective layer is provided on the outside of the curved surface structure for wear protection.

[0018] The present invention is further configured such that the body of the oral irrigator and the water storage section are set at the same height, and / or the height of the body of the oral irrigator is greater than the height of the water storage section.

[0019] The present invention is further configured such that both magnetic parts of the water flosser body are metal blocks, and / or the magnetic parts are permanent magnets.

[0020] The present invention is further provided that the water tank has a valve inside the water pumping port, and the valve is used to prevent water leakage.

[0030] 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.

[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0032] This embodiment discloses a water flosser with a detachable water tank. The water flosser has a first direction, which is perpendicular to the height direction of the water flosser, specifically the length direction. The water flosser body 1 can be fitted against the water tank 2 along its length direction to avoid obstructing the water pump inlet of the water tank 2, and then fitted downwards into the water tank 2 along its height direction to complete the assembly. Figures 1-6 As shown, it includes:

[0033] Water flosser body 1;

[0034] Water tank 2 is connected to the body 1 of the oral irrigator. Water tank 2 includes a support part 26 and a water storage part 27. The contact surface between the water storage part 27 and the body 1 of the oral irrigator is curved, and the curved surface has a height difference in the first direction.

[0035] The support part 26 and the water storage part 27 are respectively equipped with the two magnetic suction parts of the water flosser body 1, which are provided with a second permanent magnet 25 and a first permanent magnet 23. The first permanent magnet 23 and the second permanent magnet 25 are used to restrict the movement of the water flosser body 1.

[0036] It should be noted that the water flosser body 1 and the water tank 2 are magnetically engaged and fixed by their curved surfaces. Firstly, the water flosser body 1 and the water tank 2 have two sets of magnetic structures: the top of the side of the water flosser body 1 closest to the water tank 2 and the end that fits against the water tank 2 both have magnetic attachments. Correspondingly, the water tank 2 is equipped with a first permanent magnet 23 and a second permanent magnet 25, which respectively restrict the movement of the water flosser body 1 in the first direction and the height direction. Secondly, the side of the water flosser body 1 closest to the water tank 2 is also curved, and the water tank 2 is correspondingly curved. This misalignment allows for a locking mechanism, restricting the movement of the water flosser body 1 in the second direction. Here, the second direction refers to the width direction, which is perpendicular to both the first and height directions.

[0037] By using the curved surface of the water tank 2 and the water flosser body 1, the movement of the water flosser body 1 in the second direction is restricted. The first permanent magnet 23 and the second permanent magnet 25 cooperate with the magnetic attraction part of the water flosser body 1 to form a magnetic attraction structure, which restricts the movement of the water flosser body 1 in the first direction and the height direction. This forms an assembly structure of the water flosser body 1 and the water tank 2, avoiding the dead corners of hygiene that exist in snap-fit ​​connections, and avoiding the problem that the water flosser body 1 is easy to detach from the water tank 2 after assembly due to force, which exists in a single magnetic attraction structure.

[0038] like Figure 4 and Figure 5 As shown, the curved surface includes a third stop surface 2202 and symmetrically arranged first stop surfaces 21 and second stop surfaces 22;

[0039] The first stop surface 21 and the second stop surface 22, as well as the second stop surface 22 and the third stop surface 2202, are connected by a transition surface 2201.

[0040] It should be noted that setting different abutment surfaces can increase the area of ​​the friction contact surface, thereby increasing the friction force. Among them, the transition surface 2201 serves to connect the curved surface and the flat surface to form a smooth transition. The third abutment surface 2202 with a planar structure is easy to slot for installing permanent magnets. The permanent magnet with a planar adsorption surface has stable adsorption and is not easy to misalign.

[0041] like Figures 4-6 As shown, the first stop surface 21 and the third stop surface 2202 are both planes and are set perpendicular to the first direction, while the second stop surface 22 is a smooth single curved surface.

[0042] It should be noted that the first stop surface 21 and the third stop surface 2202 are parallel or intersecting.

[0043] like Figures 2-5 As shown, the first stop surface 21 is provided with a mounting groove for installing the first permanent magnet 23. The first permanent magnet 23 is embedded in the mounting groove and covered by an openable and closable cover 24.

[0044] like Figures 2-5 As shown, the support part 26 has a water storage cavity, and the second permanent magnet 25 is located on the side of the support part 26 near the body 1 of the oral irrigator.

[0045] It should be noted that both the support part 26 and the water storage part 27 of the water tank 2 have water storage chambers, and the water storage chambers are connected to each other. The second permanent magnet 25 is located on the side of the support part 26 near the body 1 of the water flosser, and the other side is provided with a water tank cover. The water tank cover is removable so that the internal parts of the water tank 2 can be observed and repaired after disassembly.

[0046] like Figure 2 and Figure 5 As shown, the support part 26 is equipped with a water inlet on the water inlet of the water flosser body 1, and the water inlet protrudes from the upper surface of the support part 26.

[0047] like Figure 5 and Figure 6 As shown, the side of the water flosser body 1 that is in contact with the water storage section 27 has a raised curved structure, and the outside of the curved structure is provided with a protective layer for wear protection.

[0048] like Figures 1-4 As shown, the water flosser body 1 and the water storage section 27 are set at the same height, and / or the height of the water flosser body 1 is greater than the height of the water storage section 27.

[0049] like Figures 1-6 As shown, both magnetic parts of the water flosser body 1 are metal blocks, and / or the magnetic parts are permanent magnets.

[0050] like Figures 1-5 As shown, the water tank 2 has a valve inside its water pumping port to prevent leakage.

[0051] Working principle: The curved surface of the water tank 2 and the water flosser body 1 restricts the movement of the water flosser body 1 in the second direction. The first permanent magnet 23 and the second permanent magnet 25 cooperate with the magnetic attraction part of the water flosser body 1 to form a magnetic attraction structure, which restricts the movement of the water flosser body 1 in the first direction and the height direction. This forms an assembly structure between the water flosser body 1 and the water tank 2, avoiding the dead corners of hygiene that exist in snap-fit ​​connections, and avoiding the problem that the water flosser body 1 is easy to detach from the water tank 2 after assembly due to force, which exists in a single magnetic attraction structure. This achieves a detachable connection between the water tank 2 and the water flosser body 1, and facilitates cleaning.

[0052] 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.
