Description

Technical Field

[0001] This application relates to the field of oral irrigator technology, and in particular to a water tank and oral irrigator equipped with a one-way sealing valve structure. Background Technology

[0002] Most existing water tanks for oral irrigators adopt an integrated or semi-sealed connection structure design with the main body. The water intake is usually located at the bottom of the tank, and the water supply during oral irrigation is achieved by directly connecting the bottom water intake port to the water pump in the main body. The sealing and water supply path stability are maintained by the fixed assembly relationship between the water tank and the main body.

[0003] The core function of this type of water tank is to provide storage and transmission of cleaning water for the oral irrigator. The sealed design prevents internal liquid leakage, and the bottom water absorption structure ensures that water can be continuously and stably delivered to the oral irrigator during use, meeting the needs of daily oral cleaning scenarios.

[0004] However, such oral irrigators still have defects when in use: when the water tank is at the bottom, the water tank cannot be disassembled independently for water intake, resulting in leakage while the water is being filled, and water will also leak when the water tank is placed alone. Utility Model Content

[0005] In view of the above problems, the present invention provides a water tank and a water flosser with a one-way sealing valve structure to overcome or at least partially solve the above problems.

Detailed Implementation

[0026] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] The inventors discovered through analysis of existing technology that when the water tank's water intake position is at the bottom, the water tank cannot be disassembled independently for water intake. During the water intake process, it must remain connected to the main body, which easily leads to leakage while water is being drawn. Furthermore, the water tank also leaks when placed alone after disassembly, limiting the flexibility of its use and making it impossible to store or carry the water tank separately.

[0028] Reference Figure 1This diagram shows a partial cross-sectional view of a water tank with a one-way sealing valve structure according to the present invention. Specifically, it may include the following structure: a water tank body 1; the water tank body 1 has at least one connecting hole 11, and a movable valve 111 is disposed within the connecting hole 11, the movable valve 111 moving up and down within the connecting hole 11; the connecting hole 11 includes a first section 112 and a second section 113; the first section 112 has a water passage 1121; when the movable valve 111 is located in the first section 112, the water storage chamber of the water tank body 1 communicates with the second section 113 through the water passage 1121; when the movable valve 111 is located in the second section 113, the movable valve 111 closes the water passage 1121.

[0029] In the embodiments of this application, addressing the problem in the prior art that water tanks cannot be independently disassembled for water intake and leak when placed alone after disassembly, this application provides a solution to control the water flow and sealing state of the water tank body 1's water storage chamber by moving an active valve 111 within a two-section connecting hole 11 and cooperating with a water passage 1121 provided in the first hole section 112. Specifically, the solution includes a water tank body 1; the water tank body 1 has at least one connecting hole 11, and an active valve 111 is provided within the connecting hole 11, the active valve 111 moving up and down within the connecting hole 11; the connecting hole 11 includes a first hole section 112 and a second hole section 113; the first hole section 112 has a water passage 1121; when the active valve 111 is located in the first hole section 112, the water storage chamber of the water tank body 1 is connected to the second hole section 113 through the water passage 1121; when the active valve 111 is located in the second hole section 113, the active valve 111 closes the water passage 1121. By setting a connection hole 11 with a movable valve 111 in the water tank, and setting a water passage 1121 in the first hole section 112, the movable valve 111 can move up and down. When disassembling to connect water, the movable valve 111 moves to the second hole section 113 to close the water passage 1121, and the water tank can be separated independently without leakage. At the same time, when the water tank is put back for use, the movable valve 111 moves to the first hole section 112, and the water storage chamber is connected to the second hole section 113 through the water passage 1121 of the first hole section 112, ensuring the smooth restoration of the water absorption and conduction function.

[0030] The following will further describe a water tank equipped with a one-way sealing valve structure in this exemplary embodiment.

[0031] It should be noted that the connecting hole 11 is an axial through hole penetrating the water tank body 1. Its interior is divided into two coaxial sub-hole segments along its length, namely the first segment 112 and the second segment 113. The movable valve 111 is a sealing component that can slide up and down along the axial direction of the connecting hole 11. Its outer diameter is clearance-fitted with the inner diameter of the connecting hole 11. By moving up and down, it enables or closes the water passage 1121. When the movable valve 111 moves to the first segment 112, it forms a non-sealing contact with the inner wall of the first segment 112, allowing water to flow through. When the movable valve 111 moves to the second segment 113, it fits tightly against the inner wall of the second segment 113, blocking the water flow.

[0032] As an example, the active valve 111 may be a ball valve, a piston valve, or a diaphragm valve.

[0033] In one specific implementation, when the movable valve 111 is a plunger valve structure, during water filling, the insertion and removal device moves the movable valve 111 to the first orifice section 112. At this time, the water storage chamber of the water tank body 1 is connected to the second orifice section 113 through the water passage 1121. When the insertion and removal device is pulled out, the movable valve 111 moves to the second orifice section 113, and the movable valve 111 closes the water passage 1121. The cooperation between the movable valve 111 and the first orifice section 112 and the second orifice section 113 ensures that the water tank body 1 can accurately control the water flow during actual use, significantly improving the product's durability and user experience.

[0034] In one embodiment of this application, the connecting hole 11 is provided with a stop hole 114, the diameter of which is smaller than the diameter of the movable valve 111.

[0035] It should be noted that the stop hole 114 is a limiting structure opened axially on the inner wall of the connecting hole 11. Its diameter is smaller than the maximum outer diameter of the movable valve 111. It is used to limit the movement stroke of the movable valve 111 in the connecting hole 11 and prevent the movable valve 111 from disengaging from the connecting hole 11 due to excessive movement.

[0036] In one embodiment of this application, the movable valve 111 is annular, and the side of the movable valve 111 is provided with an annular groove.

[0037] It should be noted that the annular movable valve 111 refers to a movable valve 111 structure with an annular cross-section. Its outer ring contacts the inner wall of the connecting hole 11, and the inner ring forms a hollow channel. The annular groove is a recessed structure opened circumferentially on the side of the movable valve 111, used to enhance the contact sealing between the movable valve 111 and the connecting hole 11. Through the annular structure design, the contact area between the movable valve 111 and the connecting hole 11 is increased. Combined with the sealing function of the annular groove, the sealing performance of the movable valve 111 is effectively improved, while the weight of the movable valve 111 is reduced, and the energy consumption for driving the movable valve 111 to move is reduced.

[0038] As an example, the cross-sectional shape of the annular groove can be rectangular, V-shaped, or semi-circular.

[0039] In one specific implementation, when the cross-sectional shape of the annular groove is V-shaped, the V-shaped annular groove, combined with the elasticity of the silicone material of the movable valve 111, can still maintain a low leakage rate under high pressure scenarios. At the same time, the annular structure of the movable valve 111 reduces water flow resistance, making it suitable for the continuous water flow control requirements of industrial equipment.

[0040] In one embodiment of this application, the connecting hole 11 further includes a third hole segment 115, and the third hole segment 115 is provided with a sealing ring 1151.

[0041] It should be noted that the third segment 115 is the third sub-segment of the connecting hole 11 along the axial direction. Its position is independently set outside the first segment 112 and the second segment 113, and its function is to connect with external components. The sealing ring 1151 is an annular sealing component set on the inner wall of the third segment 115 to prevent leakage when the third segment 115 is connected to other components. The independent design of the third segment 115 expands the function of the connecting hole 11, and, together with the sealing ring 1151, ensures the sealing performance of the connection and improves the compatibility of the water tank body 1 with other equipment.

[0042] As an example, one or more sealing rings 1151 may be provided, spaced apart along the axial direction of the third hole segment 115.

[0043] In one specific implementation, when two annular sealing grooves are provided axially on the inner wall of the third bore section 115, nitrile rubber O-rings and silicone rubber O-rings are respectively embedded. When the drain pipe joint is screwed into the third bore section 115, the two O-rings respectively bear the sealing requirements of the low-pressure and high-pressure areas. Through the double O-ring sealing structure of the third bore section 115, the leakage risk is significantly reduced while meeting the connection requirements of multiple pressure levels.

[0044] In one embodiment of this application, a water tank bottom cover 2 is also included, which is connected to the bottom of the water tank body 1.

[0045] It should be noted that the water tank bottom cover 2 is a bottom sealing component of the water tank body 1. Its function is to protect the internal components of the water tank, such as the connection hole 11 and the movable valve 111, while also providing external support. The independent water tank bottom cover 2 design enables modular assembly of the water tank body 1, and facilitates cleaning or maintenance of the water tank interior, thereby improving the maintainability and service life of the product.

[0046] As an example, the connection method of the water tank bottom cover 2 can be threaded connection, snap-fit ​​connection, quick-release connection or ultrasonic welding.

[0047] In one specific implementation, when the connection between the water tank bottom cover 2 and the water tank body 1 is made by ultrasonic welding, the two are fused together by ultrasonic energy, which not only ensures the sealing of the connection part, but also avoids the use of additional fasteners.

[0048] In one embodiment of this application, the bottom cover 2 of the water tank is provided with a boss 21, and the position of the boss 21 corresponds to the position of the movable valve 111.

[0049] It should be noted that the boss 21 is an arc-shaped structure extending upward from the bottom cover 2 of the water tank, and its height matches the travel of the movable valve 111. The axis of the boss 21 coincides with the axis of the movable valve 111, and its position corresponds to that of the movable valve 111. It is used to support the movable valve 111, limit its radial swing, or transmit driving force. Through the corresponding design of the boss 21 and the movable valve 111, stable radial support is provided for the movable valve 111.

[0050] As an example, the surface of boss 21 may be provided with anti-slip texture, such as straight lines or a mesh pattern.

[0051] In one specific implementation, a boss 21 with a textured, non-slip surface is provided at the bottom of the water tank body 1. The boss 21 is used to limit the movement of the movable valve 111, thereby improving the stability of the movement of the movable valve 111.

[0052] In one embodiment of this application, a water inlet 12 is provided on one side of the water tank body 1, and a detachable water inlet cover 121 is installed on the water inlet 12.

[0053] It should be noted that the water inlet 12 is an opening on the water tank body 1 for injecting liquid, and the removable water inlet cover 121 is a sealing component that matches the water inlet 12 to prevent liquid leakage or dust from entering. The design of the removable water inlet cover 121 enables convenient water filling and cleaning of the water tank, while preventing accidental liquid leakage or contaminant entry.

[0054] As an example, the connection between the water inlet 12 and the water inlet cover 121 can be a threaded connection, a snap-fit ​​connection, or a magnetic connection.

[0055] In one specific implementation, the water inlet cap 121 is connected to the water inlet 12 via a snap-fit. The water inlet 12 is circular and located on the side of the water tank body 1. The water inlet cap 121 is also circular. Through the combination of snap-fit ​​connection and silicone sealing ring, the water inlet 12 can be detachably closed and has high sealing performance. At the same time, the anti-slip knob improves the ease of operation.

[0056] In one embodiment of this application, the active valve 111 is made of soft rubber material.

[0057] It should be noted that the soft rubber material refers to a polymer material with elasticity. The active valve 111 has softness and resilience, and can achieve a seal with the connection hole 11 through its own deformation, which reduces the cost of components and the complexity of assembly, while improving the reliability of the seal.

[0058] Reference Figure 2 The diagram shows an exploded structural schematic of a water flosser according to the present invention. In one embodiment of this application, a water flosser is also provided, including a water flosser body and a water tank with a one-way sealing valve structure as described in any of the above claims. The water flosser body and the water tank body 1 are detachably connected. The one-way sealing valve structure of the water tank is installed inside the water tank body 1. The water flosser body includes a bottom cover 3. The movable valve 111 is provided with a first groove 1111. The bottom cover 3 is inserted into the first groove 1111 of the movable valve 111. When the movable valve 111 moves to the stop hole 114, the bottom cover 3 can be pulled out.

[0059] It should be noted that the movable valve 111 is made of soft rubber. When the bottom cover 3 of the body is inserted into the movable valve 111, the air in the hole of the movable valve 111 is expelled. The fit between the movable valve 111 and the bottom cover 3 of the body is an interference fit, and the inner wall of the connection hole 11 between the movable valve 111 and the water tank body 1 is also an interference fit. When the bottom cover 3 of the body needs to be pulled out, the interference fit between the movable valve 111 and the inner wall of the connection hole 11 of the water tank body 1 will generate movement resistance; however, since the bottom cover 3 of the body has expelled the air in the hole of the movable valve 111 when it is inserted, and the mating surfaces of the two are smooth, a negative pressure suction force will be generated when the air is expelled during relative movement under force. This allows the bottom cover 3 of the body to overcome the friction between the movable valve 111 and the inner wall of the connection hole 11 of the water tank body 1, and move together with the movable valve 111 to the stop hole 114, ultimately achieving forced separation. This enables quick disassembly of the oral irrigator body and the water tank, improving the ease of use of the product.

[0060] In one embodiment of this application, the bottom cover 3 of the body includes a snap-fit ​​part; the side of the water tank body 1 is provided with a snap-fit ​​block 13, and the snap-fit ​​part snaps into the snap-fit ​​block 13 of the water tank body 1.

[0061] It should be noted that the snap-fit ​​part is an elastic protrusion extending vertically from the bottom cover 3 of the body, and the snap-fit ​​block 13 is a protrusion structure set vertically on the side of the water tank body 1. The shape of the snap-fit ​​block 13 matches that of the snap-fit ​​part; for example, if the snap-fit ​​part is a barb, the snap-fit ​​block 13 is an L-shaped groove. Through the snap-fit ​​design of the snap-fit ​​part and the snap-fit ​​block 13, the quick disassembly and locking of the water flosser body and the water tank are realized. At the same time, the elastic deformation provides a certain amount of cushioning, improving the stability of the product during use.

[0062] As an example, the number of snap-fit ​​parts can be 2 or 4, symmetrically distributed on both sides of the bottom cover 3 of the fuselage.

[0063] In one specific implementation, the bottom cover 3 of the device has two symmetrically distributed snap-fit ​​parts, and the left and right sides of the water tank body 1 each have a snap-fit ​​block 13. When the bottom cover 3 of the device is aligned with the water tank body 1, the snap-fit ​​parts are inserted into the grooves of the snap-fit ​​blocks 13 along the guide slope, and the snap-fit ​​parts are snapped into the bottom of the groove due to elastic deformation; during disassembly, the snap-fit ​​parts are pried outward with fingers to disengage them from the snap-fit ​​blocks 13, thus completing the separation. Through the cooperative design of the two symmetrically distributed snap-fit ​​parts and the snap-fit ​​blocks 13, combined with the guide slope, the quick disassembly and locking of the water flosser body and the water tank are achieved.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
