Description

Technical Field

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

[0002] A water flosser is an auxiliary tool for cleaning the oral cavity. It uses pulsed water jets to clean teeth and between teeth.

[0003] Chinese patent CN219895987U discloses a nozzle mounting structure for a water flosser, including a handle and a nozzle. The handle includes a water outlet cap communicating with a water pump, a locking switch, and a return spring. The water outlet cap has a connecting part, and the nozzle has a connector that can be inserted into the connecting part. The nozzle is installed by engaging the latch on the locking switch with the slot of the nozzle. When the nozzle needs to be removed, pushing the locking switch will move the latch to disengage it from the slot. After the nozzle is unlocked, it can be removed. The insertion and removal are smooth and comfortable, and the operation is convenient.

[0004] However, when the clip and nozzle are in contact to position the nozzle, the nozzle pressure is very high when the nozzle is blocked or partially blocked. Because there is a gap in the clip assembly, the surfaces are easily slipped when pressed together, which may cause the nozzle to slip out. Utility Model Content

[0005] To overcome the problems existing in the related technologies, this application aims to provide a nozzle mounting structure for a dental flosser that can increase contact force through point contact and prevent the nozzle from slipping out.

[0006] This application is achieved through the following technical solution.

[0007] This technical solution provides a nozzle mounting structure for a water flosser, used to lock and release the water flosser nozzle in conjunction with the water flosser body, including: a locking member, the locking member being engaged with a slot in the water flosser nozzle, and a clearance groove provided on the side of the locking member that abuts against the slot;

[0008] The clearance groove is configured such that the locking member abuts against the inner wall of the slot only through the contact surface formed by the outer edge of its abutment surface, or the circumferential contact edge, or discrete contact protrusions, thereby achieving surface contact, line contact, or continuous point contact between the locking member and the slot.

[0009] This technical solution increases the contact force by using the locking part and the groove of the water flosser nozzle as point contact, making it less likely for the water flosser nozzle to slip out. The relief groove of the locking part is an arc surface structure, which reduces the stress on the locking part and makes it less likely for the locking part to break.

[0010] The present invention is further configured such that the clearance groove is an arc-shaped groove, which is used to reduce the stress on the locking component.

[0011] The present invention is further configured such that the clearance groove is a "V" shaped groove.

[0012] The present invention is further configured such that the clearance groove is a stepped groove.

[0013] The present invention is further configured such that the body of the water flosser is provided with a release button, and the locking element is a buckle formed on the release button.

[0014] The present invention is further configured such that the locking member is an elastic block disposed inside the body of the water flosser, and the elastic block undergoes elastic deformation through the clearance groove.

[0015] The present invention is further configured such that an arc-shaped guide surface is provided on the side of the elastic block facing away from the clearance groove, and the arc-shaped guide surface is used to cooperate with the clearance groove to cause the elastic block to undergo elastic deformation.

[0016] The present invention is further provided that the side of the locking member that abuts against the slot is provided with a protrusion, and the protrusion abuts against the slot.

[0017] The present invention is further configured such that the protrusion is provided on the outer periphery of the locking member, and the cross section of the protrusion is arc-shaped or triangular.

[0018] 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

[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 discloses a nozzle mounting structure for a water flosser, used to lock and release the water flosser nozzle 3 in conjunction with the water flosser body 1, such as... Figures 1-6 As shown, it includes: a locking member 2, which is engaged in the slot 31 of the water flosser nozzle 3, and the side of the locking member 2 that abuts against the slot 31 is provided with a relief groove 21;

[0030] The clearance groove 21 is configured such that the locking member 2 abuts against the inner wall of the slot 31 only through the contact surface formed by the outer edge of its abutment surface, or the circumferential contact edge or discrete contact protrusions, thereby achieving surface contact, line contact or continuous point contact between the locking member 2 and the slot 31.

[0031] It should be noted that existing water flossers lock and release the nozzle by having a release button snap into the nozzle's slot.

[0032] like Figure 5 As shown, the locking part 2 is an arc-shaped structure that matches the slot 31. The bottom of the locking part 2, which abuts against the slot 31, has an avoidance groove 21 to prevent the buckle from contacting the nozzle surface to position the nozzle. If the surfaces are pressed together, the nozzle may slip and be pressured out.

[0033] It should be noted that when the locking member 2 is fully engaged in the slot 31, a certain gap will be maintained between the relief groove 21 and the inner wall of the slot 31, and no contact will occur. The actual contact and constraint force is generated by the outer edge of the locking member 2 on the contact surface outside the relief groove. This outer edge preferably forms a continuous annular edge. During the assembly process, this annular edge mainly makes sliding contact with the inner wall of the slot 31, eventually forming a stable line contact state. This design greatly increases the contact force between the locking member and the slot, which can prevent the nozzle from slipping out.

[0034] The outer edge can also be a contact surface. The contact surface can be flat or have anti-slip grooves. The contact surface can be parallel to the inner wall of the slot 31 to form a surface contact, or the contact surface can be non-parallel to the inner wall of the slot 31 to form a line contact. Alternatively, the outer edge can be multiple continuous protrusions to form continuous point contact.

[0035] By making point contact between the locking member 2 and the slot 31 of the water flosser nozzle 3, the contact force is increased, making it difficult for the water flosser nozzle 3 to slip out. The relief groove 21 of the locking member 2 has an arc surface structure, which reduces the stress on the locking member 2 and makes it less likely for the locking member 2 to break.

[0036] like Figures 2-6 As shown, the clearance groove 21 is an arc-shaped groove used to reduce the stress on the locking component 2.

[0037] like Figures 2-6 As shown, the clearance groove 21 is a "V" shaped groove.

[0038] like Figures 2-6 As shown, the clearance groove 21 is a stepped groove.

[0039] It should be noted that the purpose of opening the clearance groove 21 on the locking member 2 is to change the surface contact to point contact in order to increase the contact force. The structure of the clearance groove 21 can be an arc groove, a stepped groove, or a "V" shaped groove, etc.

[0040] like Figures 1-6 As shown, the water flosser body 1 is provided with a release button 11, and the locking element 2 is a buckle formed on the release button 11.

[0041] It should be noted that the locking part 2 can be integrally formed with the release button 11 to retain the original operating mode. Pressing the release button 11 will disengage the locking part 2 from the slot 31 to remove the nozzle.

[0042] like Figures 1-6 As shown, the locking element 2 is an elastic block located inside the body 1 of the water flosser, and the elastic block undergoes elastic deformation through the clearance groove 21.

[0043] It should be noted that the locking member 2 can be integrally formed with the water flosser body 1, or it can be installed on the water flosser body 1. The locking member 2 is elastic so that when the water flosser nozzle 3 is inserted, the locking member 2 deforms in the direction of nozzle insertion, allowing the nozzle to pass through and finally lock into the nozzle slot 31. When the water flosser nozzle 3 is removed, the locking member 2 deforms in the removal direction to remove the nozzle.

[0044] like Figure 3 As shown, an arc-shaped guide surface is provided on the side of the elastic block facing away from the clearance groove 21. The arc-shaped guide surface is used to cooperate with the clearance groove 21 to make the elastic block undergo elastic deformation.

[0045] It should be noted that setting an arc-shaped guide surface can reduce the difficulty of deformation of the locking part 2, and prevent the water flosser nozzle 3 from being difficult to insert and remove.

[0046] like Figure 2 and Figure 3 As shown, the side of the locking member 2 that abuts against the slot 31 is provided with a protrusion, and the protrusion abuts against the slot 31.

[0047] like Figure 2 and Figure 3 As shown, the protrusion is located on the outer periphery of the locking member 2, and the cross-section of the protrusion is arc-shaped or triangular.

[0048] It should be noted that the locking part 2 may not have the clearance groove 21, but may have a protrusion added to its outer periphery. The protrusion abuts against the slot 31 of the water flosser nozzle 3, which can also achieve point contact between the locking part 2 and the slot 31 of the water flosser nozzle 3, thereby increasing the contact force.

[0049] Working principle: The locking part 2 and the slot 31 of the water flosser nozzle 3 make point contact, which increases the contact force and makes it difficult for the water flosser nozzle 3 to slip out. The relief groove 21 of the locking part 2 has an arc surface structure, which reduces the stress of the locking part 2 and makes it less likely to break.

[0050] 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.
