Fig. 1 to 4 show a dental prophylaxis device 1 according to some embodiments of the present invention, which dental prophylaxis device 1 is operable to spray a high-speed liquid stream for cleaning teeth surfaces, teeth gaps and/or gums by impact, which can be used for daily oral care by ordinary consumers, and which is compact, portable and hygienic. The dental scaler 1 is suitable for hand holding, and in some embodiments, may include a cylindrical main body 10, a nozzle 20 detachably connected to a front end of the main body 10, a suction pipe 30 telescopically disposed at a rear end of the main body 10, a cylindrical front cover 40 detachably fitted to a front area of the main body 10, and a cylindrical rear cover 50 detachably fitted to a rear area of the main body 10. The host 10 may include a pump, a control circuit electrically connected to the pump, a rechargeable battery electrically connected to the pump and the control circuit, and the like (not shown). The front cover 40 can also be sleeved on the rear area of the main body 10 to serve as a water tank. The liquid inlet of the pump in the main body 10 is communicated with the suction pipe 30, and the liquid outlet is communicated with the spray pipe 20, so that the liquid in the front cover 40 as the water tank can be sequentially ejected through the suction pipe 30, the pump and the spray pipe 30.

The main body 10 may in some embodiments comprise a cylindrical first portion 11 in a front region, a cylindrical second portion 12 in a rear region, and a cylindrical third portion 13 coaxially connecting the first portion 11 and the second portion 12. In some embodiments, the length of the first section 11 is preferably much greater (several times) than the length of the second section 12, both of which are comparable in diameter. The diameter of the third portion 13 is larger than the diameter of the first portion 11 and the second portion 12. The inner diameter of the front cover 40 is adapted to the diameters of the first part 11 and the second part 12, and the front cover 40 can be tightly sleeved on the first part 11 or the second part 12. The outer diameter of the front cover 40 is equal to the diameter of the third portion 13, so that when the front cover 40 is sleeved on the first portion 11 or the second portion 12, the outer surface is flush with the side wall surface of the third portion 13. The depth of the front cover 40 is equivalent to the length of the first portion 11, so that the front cover 40 can cover the whole first portion 11 when it is sleeved on the first portion 11. It will be appreciated that in some embodiments, to increase the volume of the front cover 40, the depth of the front cover 40 may be slightly greater than the length of the first portion 11.

The front end of the first portion 11 may be provided with a receptacle 110 for removably inserting the spout 20 therein. The socket 110 is in communication with the pump outlet, thereby communicating the nozzle 20 with the pump outlet. The sidewall of the first portion 11 may further be recessed to form a longitudinally extending receiving slot 112 and a locking member 114 disposed in the receiving slot 112, the receiving slot 112 is used for receiving the disassembled nozzle 20 therein, and the locking member 114 is used for locking the nozzle 20. The latch 114 may be made of a soft material such as silicone in some embodiments to facilitate access to the spout 20. In some embodiments, two opposite positions of the root of the first portion 11 are further provided with a first locking protrusion 116 for engaging with the front cover 40 to prevent the front cover 40 from falling off when the front cover 40 is sleeved on the first portion 11.

The second portion 12 may include two second protrusions 121, and the two second protrusions 131 are respectively disposed at two opposite positions of the sidewall near the third portion 13 for engaging with the front cover 40, so that the front cover 40 can be tightly combined with the second portion 12. The side wall of the second portion 12 may also be formed with an annular groove 120 for receiving the sealing ring 60 to provide a fluid-tight seal between the second portion 12 and the front cover 40.

The third portion 13 may include a mini-USB interface 130 in some embodiments, wherein the mini-USB interface 130 is electrically connected to a rechargeable battery in the host 10 for charging.

The front cover 40 may be cylindrical in some embodiments, and a combination portion is further disposed near the opening, and the combination portion may be, in some embodiments, two opposite positions of an inner wall surface near an edge of the opening, and respectively have a first locking groove 41 to be respectively locked with the two first locking protrusions 116 of the first portion 11, or respectively locked with the two second locking protrusions 121 of the second portion 12.

The rear cover 50 may also be a cylinder in some embodiments, and two opposite positions of the inner wall surface of the rear cover near the edge of the opening may be respectively provided with a second locking groove 51 to be respectively locked with the two second locking protrusions 121 of the second portion 12.

As shown in fig. 5, the sealing ring 60 may in some embodiments include an annular body portion 61 with a rectangular cross section and an annular wing portion 62 extending from an outer wall surface of the body portion 61 to the outside and the wing portion 62 may be present to reduce friction between the sealing ring 60 and an inner wall surface of the front cover 40 or the rear cover 50, so as to facilitate the coupling or detaching between the front cover 40 or the rear cover 50 and the second portion 12 without reducing the sealing effect. Compared with the traditional sealing ring with a circular interface, the user experience is obviously improved.

When the tooth washing device 1 is used, the following steps can be adopted: (1) the rear cover 50 in the transport state shown in fig. 1 is removed; (2) drawing the pipette 30 out of the rear end of the main body 10 (as shown in FIG. 4); (2) taking off the front cover 40, putting in a proper amount of oral cleaning liquid, and sleeving on the second part 12 (as shown in fig. 3), so that the extended straw 30 extends to the deepest part of the front cover 40; (3) removing the spout 20 from the receiving cavity 112 of fig. 2 and inserting the spout 20 into the insertion hole 110 (as shown in fig. 4); (5) finally, the power switch is turned on to operate the pump, so that the oral cleaning liquid in the front cover can be sprayed out through the spray pipe 20. After the use is finished, the transportation state can be reversely restored, so that the space is greatly saved, and the transportation device is portable.

Fig. 6 shows a tooth washing device 1a according to another embodiment of the present invention, wherein the tooth washing device 1a includes a main body 10a, and a front cover 40a and a rear cover 50a respectively covering the main body 10 a. The structure of the host 10a may be the same as the host 10 described above.
