Description

Technical Field

[0001] This utility model belongs to the field of oral care and cleaning technology, specifically relating to a detachable structure for a water flosser handle. Background Technology

[0002] As people become increasingly aware of oral hygiene, water flossers, as a highly efficient oral cleaning tool, are gaining popularity among consumers. However, traditional water flosser handles and hose connectors often use a fixed connection, which not only limits users from changing handles to different styles or functions according to personal preferences or actual needs, but also increases the difficulty of cleaning and maintenance. This is especially common in multi-user homes or public places such as dental clinics, where different users often share the same water flosser body but need to change to their own individual handles; traditional designs clearly cannot meet this need.

[0003] Furthermore, in existing technologies, the locking mechanism used to secure the connection between the handle and the hose connector housing is quite complex. It typically consists of independent elastic components, snap-fits, and buttons. This not only increases the production process and manufacturing costs during assembly, but also, due to the tolerances between multiple independent components, can easily lead to loosening, abnormal noises, or even detachment during use, seriously affecting the user experience and product lifespan. Utility Model Content

[0004] (1) Technical problems to be solved This utility model provides a detachable structure for a water flosser handle, aiming to solve the problems in the prior art where the water flosser handle and hose connector cannot be separated, and where the locking mechanism is complex, parts are scattered, resulting in low assembly efficiency and structural instability.

[0005] (2) Technical solution This utility model provides a detachable structure for a water flosser handle, including a detachable handle and a hose connector. The bottom end of the handle is provided with a plug-in cavity adapted to the hose connector. The hose connector is provided with a slot. The plug-in cavity is provided with a locking element. The locking element is provided with a pressing part and elastic feet located on both sides of the pressing part. The elastic feet are slidably engaged with the slot. When the pressing part is pressed, the two elastic feet open radially and separate from the slot, thereby unlocking the handle from the hose connector; The locking component is also provided with an elastic arm. The elastic force of the elastic arm drives the pressing part to reset, so that the two elastic feet come together and engage with the slot, thereby locking the handle and the hose connector.

[0006] Furthermore, the pressing part, the elastic foot, and the elastic arm are integrally molded structures.

[0007] Furthermore, the elastic foot is provided with a limiting groove, and the handle is provided with a limiting post. The limiting post passes through the limiting groove and is perpendicular to the elastic foot. The limiting groove is provided with a sliding surface, and the limiting post slides against the sliding surface.

[0008] Furthermore, the sliding surface is inclined relative to the axial direction of the elastic foot, and the sliding surface has a guiding effect on the deformation of the elastic foot.

[0009] Furthermore, the limiting groove is a closed limiting groove or an open limiting groove.

[0010] Furthermore, there are four elastic arms, symmetrically arranged on the upper and lower end faces of the pressing part. One end of each elastic arm is connected to the pressing part, and the other end elastically abuts against the outer wall of the insertion cavity.

[0011] Furthermore, a bottom cover is detachably connected to the bottom end of the handle, and a through hole adapted to the pressing part is opened on the side wall of the bottom cover. The pressing part extends through the through hole and out of the side wall of the bottom cover.

[0012] Furthermore, the handle is also provided with a water inlet connector and several male terminals, and the hose connector is provided with a water outlet connector and several female terminals. When the hose connector is inserted into the insertion cavity, the water inlet connector is connected to the water outlet connector, and the male terminals are connected to the female terminals.

[0013] Furthermore, the water outlet connector is provided with a valve assembly, which includes an elastic element and a valve stem. One end of the valve stem abuts against the water outlet of the water outlet connector, and the other end abuts against the elastic element. At least a portion of the valve stem is made of silicone.

[0014] Furthermore, a notch is provided on the side wall of the water inlet connector, and when the hose connector is connected to the handle, the water outlet connector communicates with the water inlet connector through the notch.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The design incorporates a one-piece locking mechanism, allowing the elastic foot on the locking mechanism to engage with the slot on the hose connector. This enables quick and easy detachment and installation of the hose connector and handle, meeting the needs of users who wish to connect and disconnect the same hose connector to multiple handles. It is particularly suitable for family members sharing the main unit, as only the handle needs to be replaced, making it both economical and hygienic. Furthermore, the one-piece locking mechanism not only reduces the number of parts and improves assembly efficiency but also enhances the overall strength and stability of the structure, fundamentally avoiding the problems of misalignment, abnormal noise, and wear caused by separate assembly.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-3 As shown, this utility model provides a detachable structure for a water flosser handle, including a detachably connected handle 1 and a hose connector 2. The bottom end of the handle 1 has a insertion cavity 11 adapted to the hose connector 2, so that when the hose connector 2 is connected to the handle 1, it is essentially housed within the handle 1. This not only makes the overall appearance of the water flosser more concise and streamlined but also reduces the risk of damage from exposed hose connector 2. The hose connector 2 has a slot 21, and the insertion cavity 11 has a locking element 3. The locking element 3 has a pressing part 31 and elastic feet 32 ​​located on both sides of the pressing part 31. The two elastic feet 32 ​​are symmetrically arranged, so that the two elastic feet 32 ​​and the pressing part 31... The overall shape is "U", and the elastic foot 32 extends into the insertion cavity 11 and is movably engaged with the slot 21, forming a block on the hose connector 2 in the insertion direction, thereby locking or unlocking the connection between the hose connector 2 and the handle 1. By making the handle 1 and the hose connector 2 detachably connected, it is easy to connect the same hose connector 2 with multiple different water flosser handles. This is especially convenient for the same family to share the same main unit, which can save the cost of the main unit and allow family members to interchange their own handles 1. It is hygienic and convenient. When the water flosser handle 1 malfunctions, only the water flosser handle 1 needs to be replaced, without replacing the entire machine and causing a waste of resources. Specifically, such as Figure 3-5As shown, the elastic foot 32 is provided with a limiting groove 321, and the handle 1 is provided with a limiting post 12. The limiting post 12 passes through the limiting groove 321 and is perpendicular to the elastic foot 32. When the pressing part 31 is pressed, the locking member 3 moves as a whole in the direction of force application, thereby causing the elastic foot 32 to be subjected to axial thrust. Since the limiting post 12 is a fixed fulcrum, the limiting groove 321 can slide relative to the limiting post 12. And due to the elastic force of the elastic foot 32, the limiting post 12 will slide against the inner wall of the limiting groove 321. Here, the surface where the limiting groove 321 abuts against the limiting post 12 is designated as the sliding surface 322. The sliding surface 322 will apply the axial thrust to the limiting post 12. Since the limiting post 12 is a fixed fulcrum, thus... A reaction force is generated and acts on the sliding surface 322. Therefore, the sliding surface 322 guides the deformation of the elastic foot 32. In this embodiment, the sliding surface 322 is inclined relative to the axial direction of the elastic foot 32, that is, the inclined direction L1 of the sliding surface 322 and the axis L2 of the elastic foot 32 form an angle A, so that the elastic foot 32 can deform along the sliding surface 322 in the inclined direction, that is, deform in the radial direction, thereby causing the two elastic feet 32 ​​to open up to each other and separate from the slot 21, realizing the unlocking operation of the handle 1 and the hose connector 2. Thus, the hose connector 2 can be easily pulled out from the handle 1 for cleaning, replacement or maintenance. The larger the angle A is, the greater the distance between the two elastic feet, and vice versa. The locking member 3 is also provided with an elastic arm 33. When the pressing part 31 is pressed, the elastic arm 33 is in a compressed state. Therefore, when the pressing part 31 is released, the elastic force of the elastic arm 33 will drive the pressing part 31 to reset, thereby causing the two elastic feet 32 ​​to be subjected to opposite axial thrust and to return to their original shape along the sliding surface 322 and move closer to each other and engage with the slot 21 again, realizing the locking function of the handle 1 and the hose connector 2. This ensures that the connection between the hose connector 2 and the handle 1 is stable during normal use and will not loosen or fall off accidentally, thus improving the flexibility and convenience of using the water flosser.

[0032] It should be noted that the pressing part 31, the elastic foot 32, and the elastic arm 33 are integrally molded structures. Through the integral molding design, the pressing force can be directly and efficiently transmitted from the pressing part 31 to the elastic arm 33, and the elastic foot 32 can be made to produce coordinated elastic deformation. This structure is not only responsive and compact, but also improves the overall strength and stability of the structure. Moreover, it fundamentally avoids the problems of misalignment, abnormal noise, and wear caused by separate assembly, significantly reduces the number of parts and assembly steps, and effectively reduces production costs.

[0033] Furthermore, such as Figure 6 As shown, the limiting groove 321 is provided with a first stop 323 and a second stop 324 arranged radially offset. The first stop 323 and the second stop 324 are two "locking points" or "stable positions" specifically designed for the limiting post 12. In the natural state, the limiting post 12 is stably held at the first stop 323 by the elastic force of the elastic arm 33, and the two elastic feet 32 ​​are close to each other and engaged with the slot 21, i.e., locked. When the pressure of pressing the pressing part 31 overcomes the elastic force of the elastic arm 33, the limiting post 12 slides from the first stop 323 into the second stop 324. The second stop 324 can force the two elastic feet 32 ​​to open, so that the two elastic feet 32 ​​are open to each other and separated from the slot 21, i.e. unlocked.

[0034] In this embodiment, the limiting post 12 is cylindrical in shape, and the inner walls of the first stop 323 and the second stop 324 are arc-shaped surfaces that are adapted to the limiting post 12, which facilitates the smooth sliding of the limiting post 12 between the two stops, reduces friction and noise, and the arc-shaped surface design also increases the stability of the limiting post 12 in the stop, reducing the possibility of accidental unlocking due to shaking or vibration.

[0035] In this embodiment, the limiting groove 321 is a closed limiting groove, which can provide stronger structural stability, prevent the limiting post 12 from coming out of the limiting groove 321 under extreme conditions, and ensure the reliability of the entire structure.

[0036] like Figure 7 As shown, in some embodiments, the limiting groove 321 is an open limiting groove. Since the two elastic feet 32 ​​have a certain elasticity, the limiting post 12 can be kept in contact with the sliding surface 322 of the elastic foot 32. Therefore, the side opposite to the sliding surface 322 can be provided with an opening, that is, it is designed as an open limiting groove. In this way, during assembly, the limiting post 12 can be more easily inserted into the limiting groove 321, improving assembly efficiency and saving production materials.

[0037] Furthermore, such as Figure 8As shown, one end of the elastic arm 33 is connected to the pressing part 31, and the other end abuts against the outer wall of the insertion cavity 11. This allows the elastic arm 33 to be elastically compressed by the outer wall of the insertion cavity 11 when it is subjected to pressure from the pressing part 31. In this embodiment, there are four elastic arms 33, which ensures that the elastic force of the elastic arms 33 is sufficient to move the limiting post 12 from the second stop 324 to the first stop 323, and makes the engagement structure between the elastic foot 32 and the slot 21 more stable and reliable. Two elastic arms 33 are symmetrically arranged on the upper and lower end faces of the pressing part 31, allowing the elastic arms 33 to distribute the pressure more evenly when subjected to pressure transmitted by the pressing part 31. This ensures that the pressing part 31 is subjected to stable force during the reset process, avoiding skewing or jamming, and also enhances the overall structural stability of the locking member 3, making it less prone to deformation or damage during long-term use and extending the service life of the locking member 3.

[0038] Preferably, such as Figure 9 As shown, for ease of processing and assembly, a bottom cover 13 is detachably connected to the bottom end of the handle 1. The insertion cavity 11 is located inside the bottom cover 13. The limiting post 12 is fixedly connected to the bottom cover 13. A through hole 131 adapted to the pressing part 31 is provided on the side wall of the bottom cover 13. The pressing part 31 of the locking member 3 extends through the through hole 131 to the side wall of the bottom cover 13. This not only makes it convenient for users to directly unlock or lock the handle 1, but also allows them to easily access the pressing part 31 without disassembling the handle 1, improving the ease of use. At the same time, the detachable nature of the bottom cover 13 also facilitates the later maintenance or cleaning of the inside of the handle 1, reducing maintenance costs.

[0039] In this embodiment, the pressing part 31 is located on the back of the handle 1, opposite to the button on the front of the handle 1. This avoids accidental unlocking of the handle 1 and the hose connector 2 due to accidental contact with the pressing part 31 during use, thus improving the safety and stability of use.

[0040] Furthermore, such as Figure 10-11 As shown, the handle 1 is provided with a water inlet connector 14, and the hose connector 2 is provided with a water outlet connector 22. The water outlet connector 22 protrudes from the end face of the hose connector 2, and the water outlet connector 22 is provided with a water outlet 221 that is compatible with the water inlet connector 14. When the hose connector 2 is inserted into the insertion cavity 11, the water inlet connector 14 automatically inserts into the water outlet 221 and communicates with the water outlet connector 22. The water outlet connector 22 tightly wraps around the water inlet connector 14, which can prevent water from seeping out from the gap between the two. During use, the user does not need to manually adjust or align the positions of the water inlet connector 14 and the water outlet connector 22, which greatly improves the efficiency and comfort of use.

[0041] Preferably, such as Figure 12 As shown, to prevent water from flowing out of the outlet connector 22 when the hose connector 2 is separated from the handle 1, which could cause leakage or damage to parts, a valve assembly 4 is also provided inside the outlet connector 22. The valve assembly 4 includes an elastic element 41 and a valve stem 42. One end of the valve stem 42 abuts against the outlet 221 of the outlet connector 22, and the other end abuts against the elastic element 41. The other end of the elastic element 41 abuts against the end face of the hose connector 2. The valve stem 42 is provided with an abutment surface 421. The area of ​​21 is larger than the area of ​​the outlet 221, and in its natural state, under the action of the elastic force of the elastic element 41, the contact surface 421 of the valve column 42 always remains in contact with the inner wall of the outlet 221, thereby sealing the outlet 221 and preventing water in the outlet connector 22 from flowing out of the outlet 221. At least a part of the valve column 42 is made of silicone material, and the silicone material part is close to the outlet 221 of the outlet connector 22, which is more conducive to sealing and contacting the outlet 221 of the outlet connector 22.

[0042] Among them, such as Figure 11 , Figure 13 The water inlet connector 14 shown has a notch 141 on its side wall. When the water inlet connector 14 enters the water outlet 221, the water inlet connector 14 abuts against the contact surface 421 of the valve column 42 and applies downward pressure, causing the elastic element 41 to be compressed. The contact surface 421 of the valve column 42 separates from the water outlet 221, allowing water in the water outlet connector 22 to flow into the water inlet connector 14 through the notch 141, thus achieving normal water supply for the water flosser. When the hose connector 2 separates from the handle 1, the water inlet connector 14 no longer applies pressure to the valve column 42, the elastic element 41 returns to its original state, and the contact surface 421 of the valve column 42 abuts against and seals the water outlet 221 again, effectively preventing water leakage and ensuring safe use.

[0043] Furthermore, such as Figure 10-11 As shown, in order to achieve electrical connection between the water flosser handle 1 and the hose connector 2 for the transmission of power or signal, the hose connector 2 is provided with several female terminals 23, and the handle 1 is provided with several male terminals 15 corresponding to the female terminals 23. When the hose connector 2 is inserted into the insertion cavity 11, the female terminals 23 and the male terminals 15 are inserted into each other. This connection method is not only simple in structure and reliable in connection, but also facilitates quick insertion and removal, improves the convenience of use, and realizes the structure that the hose connector 2 and the handle 1 can be disassembled for both water and electricity.

[0044] In this embodiment, the hose connector 2 includes a detachably connected front cover 24 and a rear cover 25. The front cover 24 is provided with a water outlet guide groove 241, one end of which is connected to the water outlet connector 22, and the other end is connected to the water outlet pipe 26. The front cover 24 is provided with a plurality of mounting posts 242 corresponding to the female terminal 23. The female terminal 23 is located inside the mounting posts 242 to position and protect the female terminal 23. There are four female terminals 23 corresponding to the male terminals 15, and they are arranged in a ring around the water outlet connector 22 and the water inlet connector 14. A wire is connected to the female terminal 23. The wire and the water outlet pipe 26 are jointly encapsulated and extend to the outside of the hose connector 2, which saves internal space and facilitates unified wiring and maintenance.

[0045] Preferably, such as Figure 9-10 As shown, the inner wall of the insertion cavity 11 is provided with a foolproof groove 111, and the hose connector 2 is provided with a protrusion 27 corresponding to the foolproof groove 111. When the hose connector 2 is inserted into the insertion cavity 11, the protrusion 27 will slide into the foolproof groove 111 to ensure that the hose connector 2 is inserted in the correct direction and position, avoiding connection failure or damage to parts due to reverse insertion or crooked insertion, and improving the accuracy and efficiency of assembly.

[0046] In this embodiment, the bottom of the handle 1 is also provided with a circuit board 16 electrically connected to the male terminal 15. The handle 1 is provided with a fixing cover 17, which is used to fix the circuit board 16. The fixing cover 17 is provided with a through groove 171 corresponding to the male terminal 15 and the water inlet connector 14, so that the female terminal 23 and the water outlet connector 22 can pass through the through groove 171 and connect to the male terminal 15 and the water inlet connector 14 respectively. A sealing gasket 18 is also provided between the fixing cover 17 and the circuit board 16. A sealing ring is also provided in the sealing gasket 18 corresponding to the male terminal 15 and the water inlet connector 14. By setting the sealing gasket 18 and the sealing ring, the sealing of the connection between the hose connector 2 and the handle 1 can be ensured, and water or moisture can be effectively prevented from entering the area where the circuit board 16 is located, so as to avoid the circuit board 16 from short circuits, damage and other faults due to moisture.

[0047] The innovation of this utility model lies in the provision of an integrally molded locking component 3, which allows the elastic foot 32 on the locking component 3 to movably engage with the slot 21 on the hose connector 2. This enables the hose connector 2 and handle 1 to be quickly and easily detached and installed, meeting the needs of users to connect and detach the same hose connector 2 with multiple handles 1. It is especially suitable for family members to share the main unit, requiring only the replacement of handle 1, which is both economical and hygienic. In addition, the integrally molded structure of the locking component 3 not only reduces the number of parts and improves assembly efficiency, but also improves the overall strength and stability of the structure, fundamentally avoiding the problems of misalignment, abnormal noise, and wear caused by separate assembly.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
