[0038] Combine the following Figure 1-Figure 8 The technical solution provided by the present invention is described in more detail.

[0039] Embodiment 1:

[0040] The water tank 1 installation structure provided by the present invention comprises a water tank 1, a mouthwash bottle 2, a plunger 73, a thimble assembly 4 and a movable spike member 5, wherein: a sealing film 21 is arranged at the water outlet of the mouthwash bottle 2, the movable spike member 5 is located at the bottom of the water tank 1, the mouthwash bottle 2 is detachably installed in the water tank 1, and the movable spike member 5 is arranged opposite to the sealing film 21; a fluid channel 71 is arranged in the plunger 73, the movable spike member 5 passes through the plunger 73 and can seal the fluid channel 71; the thimble assembly 4 is located on the fuselage 6, and when the water tank 1 is installed in place on the fuselage 6, the thimble assembly 4 lifts up the movable spike member 5, the movable spike member 5 opens the fluid channel 71, and pierces the sealing film 21, and the mouthwash in the mouthwash bottle 2 can flow into the water inlet pipe 9 of the fuselage 6 through the fluid channel 71.

[0041] Specifically, the structure of the mouthwash bottle 2 is as follows Figure 8 As shown, the mouthwash bottle 2 is fixed in the water tank 1 by means of a snap-fit ​​or threaded connection, and the sealing film 21 of the mouthwash bottle 2 faces downward. When installed in place, the sealing film 21 is arranged opposite to the movable spike member 5 at the bottom of the water tank 1, as shown in FIG. Figure 7 and Figure 1 shown.

[0042] The water tank 1 is rotatably connected to the fuselage 6. When the water tank 1 is installed in place on the fuselage 6 under the rotation of an external force, Figure 3 As shown, at this time, the ejector assembly 4 on the fuselage 6 can lift the moving spike 5, as shown in FIG. Figure 6 As shown, the moving spike 5 punctures the sealing film 21 on the mouthwash bottle 2, and the mouthwash flows from the fluid channel 71 into the water tank 1 and the water inlet pipe 9 in the body 6, as shown in FIG. Figure 4 and Figure 6 shown.

[0043] In the installation structure of the water tank 1 of this embodiment, the mouthwash bottle 2 is loaded into the water tank 1, and when the water tank 1 is installed on the body 6 and installed in place, the ejector assembly 4 lifts up the moving spike 5, and the moving spike 5 opens the fluid channel 71 and pierces the sealing film 21, and the mouthwash in the mouthwash bottle 2 can flow into the water inlet pipe 9 of the body 6 through the fluid channel 71, thereby realizing the addition and use of the mouthwash, making it easy to add the mouthwash into the water tank 1 of the water flosser, without the need to find other spike tools, facilitating operation, and ensuring the hygienic use of the mouthwash. When the mouthwash needs to be replaced, the mouthwash bottle 2 can be taken out of the water tank 1 and replaced, which is convenient to use.

[0044] As an alternative embodiment, see Figure 6 and Figure 7As shown, the movable spike member 5 includes a column 51 and a spike portion 52, wherein: a water outlet is provided on the water tank 1, the water outlet is communicated with the fluid channel 71, the column 51 passes through the inner cavity of the plunger 73, the fluid channel 71 is formed between the column 51 and the plunger 73, the spike portion 52 is fixed to the top end of the column 51, and the tapered end 521 of the spike portion 52 is arranged away from the column 51; the ejector pin assembly 4 can lift the column 51 and the spike portion 52, and make the spike portion 52 pierce the sealing film 21.

[0045] The function of the spike portion 52 is to directly pierce the sealing film 21 on the mouthwash bottle 2, so that the mouthwash enters the water tank 1 and the water supply pipe of the body 6 from the fluid channel 71.

[0046] The column 51 bears the external force of the ejector assembly 4 , and the ejector assembly 4 drives the spike portion 52 to move upward, thereby piercing the sealing film 21 .

[0047] As an alternative embodiment, see Figure 6 As shown, the outer diameter of the spike portion 52 is greater than the outer diameter of the column 51 and greater than the inner diameter of the fluid channel 71; see Figure 4 As shown, the number of the cone ends 521 is one or more than two. When the number of the cone ends 521 is more than two, the cone ends 521 are evenly spaced around the center of the spike portion 52 .

[0048] The conical end 521 structure of the above structure facilitates puncturing the sealing film 21 from the periphery of the sealing film 21, thereby ensuring that the sealing film 21 can be punctured and the mouthwash can flow out smoothly.

[0049] As an alternative embodiment, see Figure 6 and Figure 7 As shown, the movable spike member 5 also includes a soft elastic member (soft valve 53 ), the bottom of the column 51 is movably connected to the water outlet through the soft elastic member, and the soft elastic member is deformable under the action of the ejector assembly 4 .

[0050] The soft elastic part can be made of materials such as silicone. One of the functions of the soft elastic part is to connect the bottom end of the column 51 to provide support for the column 51; the second function is that the soft elastic part is deformed under the action of the ejector assembly 4, thereby reserving space for the up and down movement of the column 51 to prevent interference with the movement of the column 51.

[0051] As an alternative embodiment, see Figure 6 and Figure 7 As shown, the soft elastic member includes soft valves 53, the number of which is more than two, one end of all soft valves 53 is fixedly connected to the bottom of the column 51, a horizontal eaves 72 is provided at the bottom end of the plunger 73, and the other end of the soft valve 53 is fixedly connected to the horizontal eaves 72.

[0052] There are gaps between the soft valves 53, see Figure 6 As shown, after the sealing film 21 of the mouthwash bottle 2 is punctured, the mouthwash can enter the water tank 1 through the gap between the fluid channel 71 and the valve, and then enter the water inlet pipe 9 in the body 6 to rinse the oral cavity under the action of the pump body.

[0053] As an alternative embodiment, see Figure 6 and Figure 7 As shown, a first elastic member 54 is sleeved on the column 51 , and two ends of the first elastic member 54 are respectively against the soft elastic member (soft valve 53 ) and the spike portion 52 .

[0054] The first elastic member 54 may be a return spring. The first elastic member 54 contracts under the action of the ejector assembly 4 to move the column 51 upward to pierce the sealing film 21 , and can return the column 51 to its original position when the water tank 1 is opened, so as to facilitate replacement of the mouthwash bottle 2 .

[0055] This embodiment also provides a specific implementation of the ejector assembly 4:

[0056] See also Figure 6 and Figure 7 As shown, Figure 6 The arrow direction in the figure is the flow direction of the mouthwash. The ejector assembly 4 includes an ejector body 41, a moving column 42 and a second elastic member 43, wherein: the second elastic member 43 is sleeved on the moving column 42, one end of the second elastic member 43 is fixed on the body 6, and the other end is positioned on the moving column 42, the ejector body 41 is fixed to the top of the moving column 42, and the second elastic member 43 can drive the ejector body 41 and the moving column 42 to move downward when subjected to pressure. The second elastic member 43 can be a return spring.

[0057] See also Figure 2 As shown, before the water tank 1 is installed, the ejector body 41 is protruding from the surface of the fuselage 6 in the initial position. The water tank 1 is rotated, and the bottom of the water tank 1 presses the ejector body 41, the second elastic member 43 contracts, and the ejector body 41 descends. When the water tank 1 is installed in place on the fuselage 6, the elastic restoring force of the second elastic member 43 causes the ejector body 41 to push the soft elastic member (soft valve 53) and the column 51 upward, as shown in FIG. Figure 6 As shown, the column 51 moves upward, the spike portion 52 pierces the sealing film 21 of the mouthwash bottle 2, and the mouthwash flows into the water inlet pipe 9 from the fluid channel 71.

[0058] The second elastic member 43 reserves a space for the smooth installation of the water tank 1 , and can ensure that the ejector body 41 moves upward after the water tank 1 is installed, thereby pushing the column 51 and the spike portion 52 to move upward.

[0059] As an alternative embodiment, see Figure 1-Figure 3As shown, a mounting frame 61 is provided on the fuselage 6, and the ejector assembly 4 is provided at the bottom of the mounting frame 61; a rotating shaft 11 is fixed to one side of the water tank 1, and the rotating shaft 11 is rotatably connected to one side of the mounting frame 61. The water tank 1 can be rotated into the mounting frame 61 and installed in place under the action of external force, and can be rotated out of the mounting frame 61 under the action of external force.

[0060] When you need to disassemble the mouthwash bottle 2, refer to Figure 1 and Figure 2 As shown, the water tank 1 is held and rotated to make the water tank 1 rotate out of the installation frame 61, and the mouthwash bottle 2 can be replaced; after the mouthwash bottle 2 is replaced, the water tank 1 is rotated back into the installation frame 61 to align the ejector assembly 4 with the movable spike member 5.

[0061] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the rotating shaft 11 is arranged parallel to the axis of the water tank 1, a side opening is arranged on one side of the installation frame 61, the rotating shaft 11 is rotatably connected to the side opening, and cooperates with the installation frame 61 to form a fully enclosed frame structure.

[0062] The above structure can ensure the stability of the structure after the water tank 1 is installed in place, and prevent the water tank 1 from being separated from the body 6. It is also convenient to rotate and open the water tank 1, and convenient to replace the mouthwash bottle 2.

[0063] The water tank 1 structure of this embodiment is shown in FIG. Figure 1-Figure 2 , rotate the water tank 1 to a position away from the mounting frame 61, such as Figure 5 As shown, the mouthwash bottle 2 is installed in the water tank 1 with the sealing film 21 facing downward, see Figure 3 As shown, the water tank 1 is rotated into the installation frame 61. At this time, the water tank 1 presses the ejector body 41, and the second elastic member 43 contracts, which can ensure that the water tank 1 is smoothly installed in the installation frame 61. Figure 3 When the water tank 1 is installed in place, Figure 6 As shown, the elastic restoring force of the second elastic member 43 causes the ejector body 41 to move upward and reset, and the ejector body 41 pushes the soft valve 53, the column 51 and the spike portion 52 to move upward, the first elastic member 54 contracts, and the conical end 521 of the spike portion 52 pierces the sealing film 21 of the mouthwash bottle 2, and the mouthwash flows from the fluid channel 71 into the water tank 1 and the water inlet pipe 9, and flushes the oral cavity under the action of the pump body.
