Example 1

Referring to fig. 1-8, the present embodiment provides a dental rinse comprising: a water outlet nozzle 1, a tooth-flushing device main body 2 and a capsule puncturing and ejecting mechanism 3; the capsule puncturing and ejecting mechanism 3 is provided in the dental impactor body 2.

The capsule puncturing and ejecting mechanism 3 comprises: an operating member 31, a capsule seat 32, a piercing member 33 and an ejector member 34; the ejection piece 34 and the piercing piece 33 are arranged on the upper side and the lower side of the capsule seat 32; the operating member 31 is exposed on the surface of the main body 2 of the dental irrigator, thereby facilitating the operation of the user.

The operation member 31 is fixedly connected with the capsule seat 32 to drive the capsule seat 32 to move from an initial position to a piercing position or an ejecting position along different directions; when the operating member 31 drives the capsule seat 32 to move toward the ejecting position, the ejecting member 34 abuts against the capsule in the capsule seat 32 to drive the capsule 4 to move relative to the capsule seat 32, so as to move out of the capsule seat 32.

In the above-mentioned tooth-washing device, the capsule seat 32 is driven to move in different directions by the operating member 31 to pierce or eject the capsule 4 on the capsule seat 32. Since the piercing member 33 and the ejection member 34 are provided on the upper and lower sides of the capsule seat 32, respectively, the movement direction of the operation member 31 is also upward and downward. This way the capsule seat 32 takes up minimal space to move. Therefore, the whole tooth-flushing device main body 2 is not too large due to the addition of the puncturing and ejecting mechanism, and convenience of storage and holding and use of a user is ensured. And because the capsule seat 32 moves upwards and then reaches the ejection position, the capsule seat 32 is far away from the piercing member 33 when the capsule 4 is ejected, and the ejected capsule 4 cannot touch the piercing member 33 when being taken out by hand, so that the safety is improved.

In this embodiment, the piercing member 33 is sleeved with a return spring 35, and when the capsule seat 32 is located at the initial position, the lower surface of the capsule seat 32 abuts against the return spring 35. When the capsule seat 32 moves to the piercing position, the return spring 35 is compressed to accumulate an elastic return force. The user releases the operating member 31, and the capsule holder 32 is moved to the initial position by the return spring 35. Therefore, the capsule 4 is first in the initial position after being mounted on the capsule seat 32, in which the capsule 4 is not pierced. This allows the user to use the capsule 4 only when they need to perform the piercing. Without the capsule 4 being pierced automatically upon loading of the capsule 4.

In this embodiment, in order to insert and remove the capsule 4, the side surface of the capsule seat 32 has an opening 321 for the capsule 4 to enter and exit, and the bottom of the capsule seat 32 is also an opening surface 322. The piercing member 33 thus pierces the capsule 4 in the capsule seat 32 through this opening surface 322, allowing the liquid inside to flow out. In this embodiment, the capsule 4 is filled with mouthwash because it is applied to a dental rinse. If this capsule 4 piercing and ejecting mechanism 3 is applied to other products, such as a coffee machine, the capsule 4 is filled with coffee powder.

The flowing mouthwash needs to be mixed with the water in the water tank, for which purpose in this embodiment the side of the main body 2 of the dental appliance remote from the tap 1 has an inner shell 21 for mounting the capsule 4 piercing and ejecting mechanism 3; the lower end of the piercing member 33 is fixed to the inner housing 21 by the locking groove 331 and the locking strip 211. In this way, the installation and fixation of the piercing member 33 is realized, and the side surface of the inner case 21 is provided with a hook 212, and the water tank 22 is connected with the inner case 21 through the hook 212; and the inner housing 21 has a passage 213 communicating the water tank 22 and the capsule 4. Therefore, after the capsule 4 is pierced, the mouthwash in the capsule 4 flows into the water tank 22 through the channel 213 and is mixed with the water in the water tank 22, and the mixed water is pumped to the water outlet nozzle 1 through the piston in the tooth-rinsing device main body 2 to be sprayed, so that the water column with the mouthwash can be sprayed.

In addition, the side of the inner housing 21 has an opening 214 exposing the capsule 4, and a movable shutter 215 is installed on the opening 214, and the user needs to install or remove the capsule 4 to open the shutter 215 and otherwise close the opening 214 by the shutter 215.

In this embodiment, in order to realize that the operating member 31 can drive the capsule seat 32 to move up and down, the upper top surface of the capsule seat 32 extends upwards along the height direction to form a connecting plate 323; the connecting plate 323 is sleeved with a mounting seat 36; the connecting plate 323 has a mounting hole 324 for fixing the operating member 31, the mounting seat 36 is provided with a relief groove 361 at a position corresponding to the mounting hole 324, and the length of the relief groove 361 along the height direction is greater than the length of the mounting hole 324, when the capsule seat 32 is in the initial position, a portion of the operating member 31 passing through the relief groove 361 is spaced from the top and the bottom of the relief groove 361 by a distance respectively.

Since the portion of the operating member 31 passing through the relief groove 361 is spaced from the top and bottom of the relief groove by a distance, which means that the operating member 31 can move up or down relative to the mounting seat 36 in the initial state, the capsule seat 32 can be driven to move up or down. Since the movement mode of the operation member 31 is translational, the operation member 31 is a push button in this embodiment.

Further, since the mount 36 is stationary, the ejector 34 is disposed on the mount 36. Thus, when the capsule seat 32 moves upward relative to the mounting seat 36, the ejector member 34 can abut against the capsule 4 in the capsule seat 32 to drive the capsule 4 to move relative to the capsule seat 32.

In this embodiment, in order to implement ejection of the capsule 4 by the ejector 34, the ejector 34 has a V-shaped structure and includes a rotating shaft 341, a first swinging end 342 and a second swinging end 343, where the first swinging end 342 and the second swinging end 343 form an acute included angle; the ejector 34 is rotatably mounted on the mount 36 by a rotary shaft 341. The capsule seat 32 has a first abutment 325 cooperating with a first swinging end 342, and the capsule 4 has a second abutment 41 cooperating with a second swinging end 343;

when the operating member 31 drives the capsule seat 32 to move toward the ejecting position, the first abutting portion 325 abuts against the first swinging end 342, and the generated abutting force makes the first swinging end 342 swing through the rotating shaft 341 to drive the second swinging end 343; when the second swinging end 343 swings, the second abutting portion 41 drives the capsule 4 to move towards the opening 321 relative to the capsule seat 32, the moving direction of the capsule 4 is approximately perpendicular to the moving direction of the capsule seat 32, and the moving directions of the two are different. In this embodiment, the second abutting portion 41 is a groove disposed at the bottom edge of the capsule 4, the outer side surface of the groove is an open surface, and the second swinging end 343 enters the groove from the open surface during swinging and abuts against the other side of the groove to form a linkage fit, so as to drive the capsule 4 to pop out. By the swinging of the ejector member 34, the up-and-down linear motion of the operating member 31 can be converted into the motion of the capsule along the other direction, so that the capsule can be removed from the capsule seat by realizing the different motion directions of the capsule and the capsule seat. When the operation member 31 moves to the piercing position, the capsule seat 32 drives the capsule to move downwards until the capsule is pierced, and when the operation member 31 moves to the ejecting position, the ejection member 34 swings to push the capsule to move towards the side surface of the capsule seat 32 and towards the opening 321.

Example 2

Referring to fig. 9 to 12, this embodiment differs from embodiment 1 in that: the ejection member 34 is an ejector block, and the side of the ejector block facing the capsule 4 is an inclined surface 344. Thus, during upward movement of the capsule seat 32 relative to the mounting seat 36, the bottom of the capsule 4 will be pressed against the inclined surface 344, and the force will be generated to translate the capsule 4 relative to the capsule seat 32, thereby removing the capsule from the capsule seat 32. The rest is the same as in example 1 and will not be described again.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
