Description

Technical Field

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

[0002] In related technologies, oral irrigators have a water tank and a body, which are usually arranged vertically. In one case, the water tank is fixedly connected to the bottom of the body, and in this case, the body and water tank are arranged vertically. In another case, the water tank is retractable and connected to the bottom of the body. This reduces the length of the oral irrigator, making it smaller and easier to carry.

[0003] However, when the machine body is installed on the water tank through the water inlet, a certain amount of pressure needs to be applied, which makes the installation of the machine body and the water tank inconvenient. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application aims to provide a detachable water tank and oral irrigator, which facilitates the installation of the oral irrigator body onto the water tank.

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

[0006] Firstly, this technical solution provides a detachable water tank for connecting to the body of a water flosser and forming a flow channel with the water inlet for water supply. The tank includes: a water tank shell; a valve body corresponding to the water inlet; a water-stop ring and an axially movable valve core inside the valve body; an outer edge on the outside of the valve body; a fixed shell extending outward from one side of the outer edge; an axially protruding mounting groove on the fixed shell; a second permanent magnet embedded inside the mounting groove; and a first permanent magnet corresponding to the second permanent magnet on the water flosser body.

[0007] When the water flosser body approaches the water tank housing, the first permanent magnet and the second permanent magnet generate magnetic attraction, which applies force to the valve core and controls the valve core to open the water stop ring.

[0008] By combining the first and second permanent magnets, a magnetic attraction is generated when the water flosser body is close to the water tank shell, thereby reducing the pressure required to press and making it easier to install the water flosser body onto the water tank.

[0009] The present invention is further configured such that the valve core passes through the water-stop ring to divide itself into a driving end and a sealing end, a return spring is provided between the driving end and the water-stop ring, a sealing ring is provided outside the sealing end, and the sealing ring and the sealing surface of the water-stop ring form a separable sealing pair.

[0010] When the magnetic attraction force is applied to the drive end, the valve core axially compresses the return spring and pushes the sealing end away from the water-stop ring, causing the sealing ring to separate from the sealing surface and forming a flow channel.

[0011] When the magnetic attraction is removed, the reset spring pushes the drive end to reset, causing the sealing end to close the water-stop ring.

[0012] The present invention is further configured such that a water inlet is provided on the side of the valve body near the water inlet, a stop member is provided at the water inlet end of the water inlet, the water inlet is sleeved on the outside of the stop member, and forms an interference seal with the sealing ring provided on the outside of the stop member.

[0013] The present invention is further configured such that a filter element is provided inside the water inlet, and the filter element is snapped between the stop member and the water inlet end of the water inlet.

[0014] The present invention is further configured such that at least one expansion groove is provided on the side of the valve body away from the water inlet, and the expansion groove is used to enlarge the water inlet surface of the valve body.

[0015] The present invention is further configured such that the valve core includes at least one connecting rod, the connecting rod being used to connect the driving end and the sealing end of the valve core and to form a water passage gap.

[0016] The present invention is further configured such that the outer edge and the fixed shell cooperate with the valve body to form a recess, and the water tank shell is provided with a protrusion corresponding to the recess, and the protrusion is engaged with the recess to form a waterproof structure.

[0017] The present invention is further provided with a tank cover and a bottom cover at the two ends of the water tank shell, respectively, and the tank cover and the bottom cover are used to open or close the water tank shell.

[0018] The present invention is further configured such that the distance between the valve body and the bottom cover is greater than or equal to zero.

[0019] Secondly, this technical solution provides a dental flosser, including the detachable water tank described in the first aspect.

[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] Firstly, this embodiment discloses a detachable water tank for connecting to the water flosser body 4 and forming a flow channel with the water inlet 42 for water supply, such as... Figures 1-4 As shown, it includes: a water tank shell 1, a valve body 5 corresponding to the water inlet 42, a water stop ring 54 and an axially movable valve core 6 inside the valve body 5, an outer edge 51 outside the valve body 5, a fixed shell 52 extending outward from one side of the outer edge 51, an axially protruding mounting groove in the fixed shell 52, a second permanent magnet 53 embedded inside the mounting groove, and a first permanent magnet 43 corresponding to the second permanent magnet 53 in the water flosser body 4;

[0030] When the water flosser body 4 approaches the water tank housing 1, the first permanent magnet 43 and the second permanent magnet 53 generate magnetic attraction to apply force to the valve core 6, thereby controlling the valve core 6 to open the water stop ring 54.

[0031] It should be noted that the first permanent magnet 43 is positioned close to the water inlet 42, and the water tank shell 1 is provided with a resonant cavity close to the second permanent magnet 53. When the water flosser body 4 docks with the water tank shell 1, there is a "bang" sound. The resonant cavity can amplify the sound to indicate that the docking is complete.

[0032] By cooperating with the first permanent magnet 43 and the second permanent magnet 53, a magnetic attraction is generated when the water flosser body 4 is close to the water tank housing 1, so as to reduce the pressure required to be applied and make it easier to install the water flosser body 4 onto the water tank housing 1.

[0033] like Figure 4 As shown, the valve core 6 passes through the water-stop ring 54 to divide itself into a drive end 61 and a sealing end 62. A return spring 64 is provided between the drive end 61 and the water-stop ring 54. A sealing ring 63 is provided on the outside of the sealing end 62. The sealing ring 63 and the sealing surface of the water-stop ring 54 form a separable sealing pair.

[0034] When the magnetic attraction force acts on the drive end 61, the valve core 6 axially compresses the return spring 64 and pushes the sealing end 62 away from the water stop ring 54, so that the sealing ring 63 separates from the sealing surface and forms a flow channel.

[0035] When the magnetic attraction is removed, the reset spring 64 pushes the drive end 61 to reset, causing the sealing end 62 to close the water-stop ring 54.

[0036] It should be noted that the magnetic attraction will cause the stop member 41 to squeeze the drive end 61 of the valve core 6, causing the valve core 6 to drive the return spring 64 to deform, thereby causing the sealing ring 63 to separate from the sealing surface and form a flow channel.

[0037] like Figure 3 and Figure 4 As shown, the valve body 5 is provided with a water inlet 55 on the side near the water inlet 42. The water inlet 42 is provided with a stop member 41. The water inlet 55 is sleeved on the outside of the stop member 41 and forms an interference seal with the sealing ring on the outside of the stop member 41.

[0038] It should be noted that after the stop part 41 is embedded inside the water inlet 55, the sealing ring will ensure the sealing between the two and improve the flow channel sealing.

[0039] like Figure 3 As shown, the water inlet 42 is equipped with a filter element inside, which is snapped between the stop member 41 and the water inlet end of the water inlet 42.

[0040] like Figure 3 and Figure 4 As shown, at least one expansion groove 56 is provided on the side of the valve body 5 away from the water inlet 42. The expansion groove 56 is used to expand the water inlet surface of the valve body 5.

[0041] It should be noted that the expansion groove 56 allows the valve body 5 to come into contact with the inner wall of the water tank housing 1, thereby reducing the height of the water tank housing 1, while not affecting the flow of water into the valve body 5.

[0042] like Figure 4As shown, the valve core 6 also includes at least one connecting rod 65, which is used to connect the drive end 61 and the sealing end 62 of the valve core 6 and form a water passage gap 66.

[0043] It should be noted that the formation of the water passage gap 66 can prevent the formation of a chamber between the valve core 6 and the valve body 5, which would store water flow and affect the movement of the valve core 6.

[0044] like Figure 2 and Figure 3 As shown, the outer edge 51 and the fixing shell 52 cooperate with the valve body 5 to form a recess 57, and the water tank shell 1 has a protrusion corresponding to the recess 57. The protrusion is engaged with the recess 57 to form a waterproof structure. It should be noted that the waterproof structure can serve to waterproof and fix the valve body 5.

[0045] like Figures 1-4 As shown, the two ends of the water tank shell 1 are respectively provided with a tank cover 2 and a bottom cover 3. The tank cover 2 and the bottom cover 3 are used to open or close the water tank shell 1.

[0046] like Figures 1-4 As shown, the distance between the valve body 5 and the bottom cover 3 is greater than or equal to zero.

[0047] Secondly, this embodiment discloses a dental flosser, such as Figures 1-4 As shown, it includes a removable water tank, which is part of the first aspect.

[0048] Working principle: Through the cooperation of the first permanent magnet 43 and the second permanent magnet 53, when the water flosser body 4 is close to the water tank shell 1, a magnetic attraction is generated to promote the valve core 6 to squeeze the return spring 64, so that a flow channel is created inside the valve body 5, and the stop part 41 and its external sealing ring can be inserted into the water inlet 55, reducing the pressing force required when assembling the water flosser body 4 and the water tank, making it easier to install the water flosser body 4 onto the water tank.

[0049] 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.
