Description

Technical Field

[0001] This utility model belongs to the technical field of water dispensing devices, and in particular relates to a dental flosser that is easy to install and remove. Background Technology

[0002] Brushing teeth is the most common dental hygiene practice. However, most toothbrushes cannot penetrate the gaps, grooves, and fissures of the chewing surfaces with toothpaste. Therefore, a dental flosser is needed as an auxiliary tool to clean teeth. Dental flossers are essential hygiene products in many households. Their cleaning effect is achieved primarily through the impact of a high-speed jet of water under pressure. Currently available electric dental flossers are expensive, require charging or batteries, and are relatively bulky. A new type of faucet with a built-in dental flosser has emerged, offering both regular water flow and flossing functions. However, these faucets have two water channels, requiring manual switching to use the flosser. This switching mechanism occupies valuable space within the faucet, increasing its size and aesthetics. Furthermore, the flosser nozzle replacement mechanism and water channel switching mechanism are separate, requiring manual switching back to the flosser water channel after installing the nozzle, making operation cumbersome. The applicant previously disclosed patent CN221013542U, a water outlet component and a faucet water flosser, comprising: a water flosser body and a nozzle; the water flosser body has a water inlet channel, a first flow channel and a second flow channel are provided inside the water flosser body, and a switch valve body for connecting or disconnecting the water inlet channel and the first flow channel; the water flosser body also has a chamber for installing the nozzle, and an operating component for opening the chamber, the operating component being connected to a switching component via a reversing component; when the operating component opens the chamber, the operating component drives the switching component to move from a first position to a second position via the reversing component, connecting the nozzle to the water inlet channel through the second flow channel and closing the first flow channel. This utility model also provides a faucet water flosser, comprising: a switch handle, a faucet support base, and the above-mentioned water outlet component; the faucet support base is placed on a mounting platform, and the switch handle is movably connected to the faucet support base for connecting or disconnecting the water inlet pipe from the water outlet component. However, in market applications, it was found that users accidentally activated the device when changing the cleaning head, which could easily result in high-pressure water spray; or the complex structure, large size, and inconvenient operation of the product could also lead to misoperation and high-pressure water spray; resulting in a poor user experience and affecting the application of the product.

[0030] Reference Figure 1-7 As shown, a dental flosser that is easy to install and remove includes a flossing body 1, a flossing head 2, a quick-release assembly 3, and a foolproof assembly 4. The flossing body 1 has a flossing water channel 11, and the flossing water channel 11 has a water inlet 12 and an installation head 13 at both ends. The flossing head 2 is detachably installed in the installation head 13. The quick-release assembly 3 is located in the installation head 13. The water inlet 12 is equipped with a push switch 5. The foolproof assembly 4 is located between the quick-release assembly 3 and the push switch 5. The foolproof assembly 4 is linked with the quick-release assembly 3. After the quick-release assembly 3 removes the flossing head 2, the foolproof assembly 4 moves downward to restrict the pressing of the push switch 5. When the flossing head 2 is installed, the foolproof assembly 4 moves upward to disengage from the push switch 5.

[0031] Through the linkage between the foolproof component 4 and the quick-release component 3, after the quick-release component 3 removes the cleaning head 2, the foolproof component 4 is released from the restriction of the quick-release component 3, moves downward, and inserts below the button of the press switch 5, thereby preventing the press switch 5 from being pressed and activating the cleaning water circuit; when the cleaning head 2 is installed, the quick-release component 3 is reset, and at the same time, it drives the foolproof component 4 to move upward, the foolproof component 4 is released from the press switch 5, and the press switch 5 resumes its pressing function.

[0032] Furthermore, the foolproof component 4 is linked with the quick-release component 3 and connected to the press switch 5 to lock the press switch 5; the foolproof component 4 is provided with a linkage frame 41, a locking rod 42 and a locking spring 43, the linkage frame 41 is provided with an arc frame 411 and a linkage hole 412, the arc frame 411 is located on the outer periphery of the teeth cleaning body 1, the linkage hole 412 is located at the upper end of the arc frame 411 and is opposite to the quick-release component 3, so that the arc frame 411 moves upward when the quick-release component 3 moves backward; the locking rod 42 is vertically located at the lower end of the arc frame 411 and extends to the press switch 5; the teeth cleaning body 1 is provided with a spring seat 14 opposite to the locking rod 42, and the locking spring 43 is located between the spring seat 14 and the locking rod 42.

[0033] The foolproof component 4 works cleverly with the quick-release component 3 to achieve switching locking and releasing. The curved frame 411 avoids the water outlet, making full use of the external space of the dental cleaning body 1.

[0034] Furthermore, the quick-release assembly 3 is provided with a locking block 31, a push plate 32, and a return spring 33. The mounting head 13 is provided with a sliding groove 131 that passes through the dental cleaning water passage 11. The locking block 31 is located in the sliding groove 131. The dental cleaning head 2 is provided with a locking groove 21 corresponding to the locking block 31. The front end of the locking block 31 is provided with an arc-shaped head 311 corresponding to the locking groove 21. The locking block 31 is provided with a vertical insertion hole 312. One end of the push plate 32 is inserted into the insertion hole 312, and the upper end extends out of the mounting head 13. The return spring 33 is located in the mounting head 13 and abuts against the rear end of the locking block 31. The locking block 31 is arranged opposite to the linkage hole 412. The rear end of the locking block 31 is provided with a push rod 313 extending to the linkage hole 412. The push rod 313 abuts against the inclined surface 413 on the upper side of the linkage hole 412, so that when the push rod 313 moves backward, the arc-shaped frame 411 moves upward.

[0035] The push plate 32 of the quick-release component 3 is located at the front end, which helps to avoid accidental activation.

[0036] Furthermore, at least one of the corresponding locking rod 42 or arc-shaped frame 411 is provided on the guide groove 15 on the teeth cleaning body 1.

[0037] The guide groove 15 ensures the stability of the movement of the arc frame 411 or the locking rod 42.

[0038] The cleaning water passage 11 is provided with a flow-blocking component 6 that abuts against the cleaning head 2; the flow-blocking component 6 is provided with a flow-blocking cylinder 61, a flow-blocking plug 62, a flow-blocking push rod 63 and a compression spring 64. The flow-blocking cylinder 61 is fixed in the cleaning water passage 11 of the cleaning body 1. The flow-blocking plug 62 is provided in the flow-blocking cylinder 61. When the flow-blocking plug 62 is located at the upper end of the flow-blocking cylinder 61, the flow-blocking cylinder 61 is sealed. When the flow-blocking plug 62 is located at the lower end of the flow-blocking cylinder 61, the cleaning water passage 11 is opened. The flow-blocking push rod 63 abuts against the end of the flow-blocking plug 62. The compression spring 64 is provided at least at one point between the flow-blocking cylinder 61 and the flow-blocking push rod 63 or between the lower end of the flow-blocking cylinder 61 and the flow-blocking plug 62.

[0039] The flow-blocking component 6 is independently designed with other structures, minimizing its impact on the internal piping and ensuring good synchronization with the installation and removal of the dental cleaning tube. The compression spring 64 allows the flow-blocking plug 62 to quickly block the flow-blocking cylinder 61's piping after the dental cleaning tube is removed; after the dental cleaning tube is installed, it pushes the flow-blocking push rod 63 downwards, causing the flow-blocking plug 62 to enter the lower end of the flow-blocking cylinder 61, thus connecting the inlet 611 with the flow-blocking cylinder 61 for water outlet. A limiting platform 612 can also be located on the inner circumference of the upper end of the flow-blocking cylinder 61 to prevent the flow-blocking plug 62 from detaching upwards from the flow-blocking cylinder 61.

[0040] The lower end of the intercepting cylinder 61 is sealed, and an inlet 611 is provided on the lower side. The intercepting plug 62 is provided inside the intercepting cylinder 61. The intercepting push rod 63 abuts against the downstream end of the intercepting plug 62. The maximum outer cross-sectional area of ​​the intercepting push rod 63 is smaller than the diameter area of ​​the teeth cleaning water channel 11. A limiting platform 612 is provided inside the upper end of the teeth cleaning water channel 11 or the intercepting cylinder 61, so that when the intercepting push rod 63 or the intercepting plug 62 abuts against the limiting platform 612, the intercepting plug 62 seals the intercepting cylinder 61. The thickness of the intercepting plug 62 is smaller than the height of the inlet 611; or the intercepting cylinder 61 is flared, and the diameter of the intercepting plug 62 is smaller than the lower port diameter of the intercepting cylinder 61 and larger than the upper port diameter of the intercepting cylinder 61.

[0041] Both schemes can achieve the effect of blocking the flow when the flow-blocking plug 62 moves to the upper end of the flow-blocking cylinder 61, and opening the teeth-cleaning water passage 11 when the flow-blocking push rod 63 pushes it out to the lower end of the flow-blocking cylinder 61. The flow-blocking push rod 63 has a vertical channel on its outer periphery, so that water can flow after the teeth-cleaning water passage 11 is opened.

[0042] Furthermore, the cross-section of the flow-blocking push rod 63 is cross-shaped.

[0043] Furthermore, the cross-sectional diameter of the lower half of the flow-cutting push rod 63 is smaller than the cross-sectional length of the upper half, and the compression spring 64 is sleeved on the lower half of the flow-cutting push rod 63 and abuts against the upper half of the flow-cutting push rod 63.

[0044] The cross-shaped design prevents the upper end of the flow-stopping push rod 63 from clogging the dental cleaning tube, dental cleaning water passage 11, and flow-stopping cylinder 61.

[0045] Furthermore, compression springs 64 are provided between the flow-stopping cylinder 61 and the flow-stopping push rod 63, and between the lower end of the flow-stopping cylinder 61 and the flow-stopping plug 62.

[0046] Furthermore, the compression spring 64 is only provided between the flow-stopping cylinder 61 and the flow-stopping push rod 63, and the flow-stopping push rod 63 is fixedly connected to the flow-stopping plug 62.

[0047] Furthermore, a sealing ring 65 is provided between the intercepting cylinder 61 and the inner wall of the dental cleaning water channel 11, and between the intercepting plug 62 and the inner wall of the intercepting cylinder 61.

[0048] Furthermore, the cleaning head 2 is threaded or snapped into the mounting head 13.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
