[0047] See also Figure 5 and Figure 7 In some embodiments of the utility model, a tooth flushing device 1 suitable for connecting to a faucet 2 comprises: a nozzle 11 having an inner cavity 110 therein and provided with a water inlet 111 and a water outlet 112 connected to the inner cavity 110; a hose 12, one end of which is suitable for connecting to the faucet 2 and the other end of which is connected to the water inlet 111 of the nozzle 11; a handle 14, the handle 14 having a cavity and a slot 141 connected to the cavity, one end of the handle 14 being fixedly connected or pluggably connected to the end of the nozzle 11 provided with the water outlet 112, the hose 12 being inserted into the cavity of the handle 14 via the other end of the handle 14, and the slot 141 being provided with a first roller 142 that is movable and can squeeze the hose 12 to adjust the water pressure of the water outlet 112. Among them, the hose 12 is used to connect to the nozzle 11, one end of which is inserted into and penetrates the cavity of the handle 14 to connect to the water inlet 111. Specifically, this solution can be understood as combining the above-mentioned flow rate regulator 13 and the handle 14 into one, so that the water pressure of the water outlet 112 of the nozzle 11 can be directly adjusted on the handle 14 of the tooth flossing device, so that the user can conveniently adjust the water pressure while holding the tooth flossing device.

[0049] See also Figure 6In some embodiments of the present invention, the first roller 142 is an eccentric roller, and the profile of the eccentric roller can be regarded as a triangle with three rounded corners; specifically, by using the eccentric roller with rounded triangle design as the first roller 142, the length of the slot 141 on the handle 14 does not need to be too long, and the eccentric roller can be rotated and press the hose 12 located in the cavity of the handle 14 by only slightly rotating the eccentric roller, thereby changing the water pressure of the water outlet 112. In addition, the shaft protrusion on the eccentric roller can be located at the centroid, centroid or other position of the rounded triangle, so as to facilitate regulation to press the hose 12; the shaft protrusion and the groove on the groove wall of the slot 141 are installed in combination.

[0050] See also Figure 4 In other embodiments of the present invention, the first roller 142 may be made as follows: Figure 4 For a circular roller such as the second roller 132 shown, the length of the slot 141 is required to be slightly longer so that the circular roller can roll and translate in the slot 141 to press the hose 12 and change the water pressure of the water outlet 112. In addition, the shaft protrusion of the circular first roller 142 can be located at the center of the circle.

[0051] See also Figure 3 and Figure 4 In some embodiments of the utility model, the flow rate regulator 13 includes: a shell 131, which is a hollow structure, and the hose 12 passes through the shell 131; a second roller 132, which is movably connected to the shell 131, and can roll relative to the shell 131 along the longitudinal direction of the hose 12, and clamp the hose 12 to reduce the flow cross-sectional area of ​​the hose 12 to reduce the water pressure or water output of the water outlet 112, or loosen the hose 12 to increase the flow cross-sectional area of ​​the hose 12 to increase the water pressure or water output of the water outlet 112.

[0052] See also Figure 3 and Figure 4 In some embodiments of the present invention, the outer surface of the second roller 132 is provided with concave-convex patterns. It can be understood that the concave-convex pattern design can increase the friction between the user's fingers and the outer surface of the second roller 132, making it easier for the user to adjust the water pressure and improving the convenience of use.

[0053] See also Figure 4 In some embodiments of the present invention, the second roller 132 may be a circular roller, and the shaft protrusion provided thereon may be located at the center of the circle.

[0054] See also Figure 3In some embodiments of the utility model, two guide grooves 1311 extending in the longitudinal direction of the hose 12 are provided in the cavity of the housing 131, and the two guide grooves 1311 are respectively located on both sides of the radial direction of the hose 12, and protrusions 1321 are provided at both axial ends of the second roller 132, and each of the protrusions 1321 is respectively clamped in one of the guide grooves 1311 and can roll in the guide groove 1311 along the longitudinal direction of the hose 12. It can be understood that the above design achieves the purpose of "adjusting the size of the flow cross-sectional area of ​​the hose by the rolling action of the second roller 132 relative to the housing 131, thereby controlling the size of the outlet water pressure".

[0055] In some embodiments of the present invention, the shell 131 is wedge-shaped, and the end of the shell 131 close to the nozzle 11 is smaller in size, so that the second roller 132 can clamp the hose 12 when it is close to the end of the shell 131 close to the nozzle 11.

[0056] See also Figure 2 In some embodiments of the present invention, the nozzle 11 is in the shape of a long tube, and the water inlet 111 and the water outlet 112 are respectively located at two ends of the nozzle 11 in the longitudinal direction of the long tube.

[0057] See also Figure 2 In some embodiments of the present invention, there is one water outlet 112. It is understandable that, under the premise that the port cross-sectional area of ​​each water outlet 112 is fixed, only one water outlet 112 can maximize the water pressure, so as to facilitate flushing of stubborn dirt stains in the gaps between teeth.

[0058] See also Figure 5 , Figures 7 to 11 In some embodiments of the present invention, the end of the nozzle 11 away from the hose 12 is swollen or flat. It is understandable that the shape and size of the nozzle 11 can be modified and selected according to the actual application scenario and different design standards.

[0059] See also Figure 8 and Fig. 9 In some embodiments of the present invention, the number of the water outlets 112 is three; the three water outlets 112 are arranged in sequence along the longitudinal direction X of the nozzle 11, or the three water outlets 112 form a triangle. It is worth noting that the above-mentioned design of the water outlet 112 can make the water outlet range larger, so as to clean the outer surface of the teeth more widely.

[0060] See also Fig.10In some embodiments of the present invention, the number of the water outlets 112 is six; the six water outlets 112 are arranged in two rows along the width direction Y of the nozzle 11, and each row is provided with three water outlets 112, and the width direction Y and the longitudinal direction X of the nozzle 11 are perpendicular to each other. It is worth noting that the above-mentioned design of the water outlet 112 can make the water outlet range larger, so as to clean the outer surface of the teeth more widely.

[0061] See also Fig.11 In some embodiments of the present invention, the number of the water outlet 112 is one.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this.
