[0041] Specifically, the structure of the mouthwash bottle 2 is as shown in Figure 8 The mouthwash bottle 2 is fixed in the water tank 1 by clamping or thread connection, and the sealing film 21 of the mouthwash bottle 2 faces downward, and when installed in place, the sealing film 21 is oppositely arranged with the mobile sharp member 5 at the bottom of the water tank 1, as shown in Figure 7 and Figure 1 .

[0042] The water tank 1 is rotationally connected to the fuselage 6, and when the water tank 1 is installed in place on the fuselage 6 under external force, as shown in Figure 3 , at this time, the thimble assembly 4 on the fuselage 6 can lift the mobile sharp member 5, as shown in Figure 6 , the mobile sharp member 5 pierces the sealing film 21 on the mouthwash bottle 2, and the mouthwash flows into the water inlet pipe 9 in the water tank 1 and the fuselage 6 through the fluid channel 71, as shown in Figure 4 and Figure 6 .

[0043] When the water tank 1 mounting structure of the embodiment is installed, the mouthwash bottle 2 is installed in the water tank 1, the thimble assembly 4 lifts the mobile sharp member 5 when the water tank 1 is installed in place on the fuselage 6, the mobile sharp 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, so that the addition and use of the mouthwash are realized, the mouthwash can be conveniently added to the water tank 1 of the oral irrigator, other sharp tools are not needed, operation is convenient, and the use hygiene of the mouthwash is ensured.

[0044] As an optional implementation, refer to Figure 6 and Figure 7As shown, the mobile piercing member 5 comprises a column 51 and a piercing part 52, wherein: the water tank 1 is provided with a water outlet, the water outlet is connected 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 piercing part 52 is fixed to the top end of the column 51, and the tapered end 521 of the piercing part 52 is arranged away from the column 51; the ejector pin assembly 4 can lift the column 51 and the piercing part 52, and make the piercing part 52 pierce the sealing film 21.

[0045] The piercing part 52 is used to directly pierce the sealing film 21 on the mouthwash bottle 2, and the mouthwash enters the water tank 1 and the water supply pipe of the machine body 6 from the fluid channel 71.

[0046] The column 51 bears the external force of the ejector pin assembly 4, and drives the piercing part 52 to move upward under the action of the ejector pin assembly 4, so as to pierce the sealing film 21.

[0053] As an optional implementation, refer to Figure 6 and Figure 7 As shown, the first elastic member 54 is sleeved on the column body 51, and the two ends of the first elastic member 54 abut against the soft elastic member (soft valve 53) and the sharp part 52 respectively.

[0054] The first elastic member 54 can be a return spring. Under the action of the thimble assembly 4, the first elastic member 54 is contracted, the column body 51 is moved upward, the sealing film 21 is punctured, and when the water tank 1 is opened, the column body 51 can return to the initial position, facilitating replacement of the mouthwash bottle 2.

[0055] The embodiment also provides a specific implementation of the thimble assembly 4:

[0056] As shown in Figure 6 and Figure 7 As shown, Figure 6 the arrow direction is the flow direction of the mouthwash. The thimble assembly 4 includes a thimble 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 thimble body 41 is fixed on the top end of the moving column 42; and the second elastic member 43 can drive the thimble 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] As shown in Figure 2 Before the water tank 1 is installed, the thimble body 41 is arranged to protrude from the surface of the body 6 when in the initial position; the water tank 1 is rotated, the bottom of the water tank 1 presses the thimble body 41, the second elastic member 43 is contracted, the thimble body 41 is lowered, and when the water tank 1 is installed in place on the body 6, the elastic restoring force of the second elastic member 43 promotes the thimble body 41 to push the soft elastic member (soft valve 53) and the column body 51 upward, as shown in Figure 6 As shown, the column body 51 moves upward, the sharp part 52 punctures the sealing film 21 of the mouthwash bottle 2, and the mouthwash flows from the fluid channel 71 into the water inlet pipe 9.

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

[0059] As an optional implementation, refer to Figures 1-3As shown, a mounting frame 61 is provided on the body 6, and the ejector pin assembly 4 is located at the bottom of the mounting frame 61; a rotating shaft 11 is fixed on 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 also be rotated out of the mounting frame 61 under the action of external force.

[0060] When it is necessary to disassemble mouthwash bottle 2, see [link / reference]. Figure 1 and Figure 2 As shown, hold the water tank 1 and rotate it so that the water tank 1 moves out of the mounting frame 61, so that the mouthwash bottle 2 can be replaced; after the mouthwash bottle 2 is replaced, rotate the water tank 1 back into the mounting frame 61 so that the ejector pin assembly 4 and the movable spike 5 are aligned.

[0061] As an alternative implementation, see [link to implementation details]. 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 provided on one side of the mounting frame 61. The rotating shaft 11 is rotatably connected to the side opening and cooperates with the mounting frame 61 to form a fully enclosed frame structure.

[0062] The above structure ensures the stability of the water tank 1 after it is installed, preventing the water tank 1 from detaching from the body 6. It also facilitates the rotation and opening of the water tank 1, making it convenient to replace the mouthwash bottle 2.

[0063] The structure of water tank 1 in this embodiment is shown in [reference]. Figures 1-2 Rotate water tank 1 to the position where it is disengaged from mounting frame 61, as follows: Figure 5 As shown, the mouthwash bottle 2 is installed into the water tank 1 with the sealing film 21 facing down. (See Figure 1) Figure 3 As shown, when the water tank 1 is rotated into the mounting frame 61, the water tank 1 presses against the ejector pin 41, and the second elastic element 43 retracts, ensuring that the water tank 1 is smoothly installed in the mounting frame 61. Figure 3 As shown. When water tank 1 is installed in place, as... Figure 6 As shown, the elastic restoring force of the second elastic element 43 causes the ejector pin 41 to move upward and reset. The ejector pin 41 pushes the soft valve 53, the column 51 and the spike 52 upward. The first elastic element 54 contracts, and the conical end 521 of the spike 52 pierces the sealing film 21 of the mouthwash bottle 2. The mouthwash flows from the fluid channel 71 into the water tank 1 and the water inlet pipe 9, and is flushed in the oral cavity under the action of the pump.
