Detailed Description

The following description is provided for further details of the embodiments of the present invention with reference to the accompanying drawings, but this embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention.

As shown in fig. 1-6, an embodiment of the present invention provides a rotary extrusion type liquid dispensing device, which includes a main container 4, a piston rod 7, and a brush head 1, where the main container 4 has a straight cylindrical cavity, a piston 6 capable of sliding left and right is disposed in the cavity of the main container 4, a rotatable rotary rod sleeve 8 is disposed on the main container 4, a left end of the piston rod 7 is fixedly connected to the piston 6, a right portion of the piston rod 7 extends into the rotary rod sleeve 8, and the piston rod 7 and the rotary rod sleeve 8 are in threaded fit;

the method is characterized in that: a liquid outlet is arranged at the left end of the main body container 4, a sealing member 5 for sealing the liquid outlet is arranged at the left end of the main body container 4, the sealing member 5 has elasticity, a crack 51 is formed on the sealing member 5, the crack 51 is in a closed state in a natural state (the natural state refers to an uncompressed state), and the crack 51 can be elastically deformed into a crack through which liquid can pass after being compressed;

an adjusting tube 3 is fixed at the left end of the main body container 4, a tube opening at the right end of the adjusting tube 3 is butted with a liquid outlet at the left end of the main body container 4, a right-end one-way opening tapered fluid channel 11 which is thin at the right and thick at the left is formed at the right end of the brush head 1, a right-end opening of the fluid channel 11 is butted with a tube opening at the left end of the adjusting tube 3, a drainage rod 2 is arranged in the adjusting tube 3, the left end of the drainage rod 2 is tapered thin at the left and thick at the right, and the left end of the drainage rod 2 is inserted into the fluid channel 11 at the;

a plurality of linear capillary grooves 31 which are penetrated left and right are formed on the inner wall of the adjusting pipe 3, and the capillary grooves 31 are symmetrically distributed around the center of the adjusting pipe 3;

the main body container 4 is provided with a rotatable tail cap 9, the tail cap 9 is sleeved with the rotary rod sleeve 8, the rotary axis of the tail cap 9 is overlapped with the rotary axis of the rotary rod sleeve 8, and the tail cap 9 and the rotary rod sleeve 8 are locked in a one-way mode in the forward rotation direction of the rotary rod sleeve 8.

The embodiment of the utility model provides a theory of operation as follows:

when the tail cap corotation, because tail cap and rotary rod cover are one-way locking in corotation direction, the tail cap can drive the synchronous corotation of rotary rod cover, because piston rod and rotary rod cover are screw-thread fit, the corotation of rotary rod cover can order about the piston rod and remove left, and then promote the piston and move left, thereby make the appearance chamber pressure increase of main part container, the crack on the sealing member also becomes the breach that can supply liquid to pass through under the pressure effect elastic deformation, the liquid that the main part container held the intracavity also is crowded into the governing pipe immediately, liquid rethread drainage rod's guide gets into the fluid passage of brush head right-hand member, reach the left end tiptoe portion of brush head (the capillary phenomenon of the hair silk on the brush head) along the hair silk on the brush head again.

When the tail cap stops rotating, the piston also stops moving, the pressure of the containing cavity of the main body container is recovered, and the crack on the sealing element is recovered to be in a closed state, so that the containing cavity of the main body container is sealed again, and the liquid in the containing cavity of the main body container is separated from the brush head.

When the tail cap rotates reversely, the tail cap and the rotary rod sleeve are locked in the forward rotation direction in a one-way mode, the rotary rod sleeve cannot rotate along with the tail cap, the tail cap can only drive the rotary rod sleeve to rotate in the forward rotation mode, the rotary rod sleeve can only drive the piston rod to move leftwards, the piston can only be pushed leftwards and cannot return rightwards, liquid in the containing cavity of the main container is always in a full state, the tail cap can be rotated in the forward rotation mode at every time, the liquid can smoothly flow out, and the phenomenon of discontinuous liquid outlet and idle rotation cannot occur.

When the tail cap rotates forward too fast, the liquid squeezed into the adjusting pipe is increased, at the moment, the excessive liquid can be stored in each capillary groove on the inner wall of the adjusting pipe, the long and thin capillary grooves can lock the excessive liquid through capillary phenomenon, so that the phenomenon that a large amount of liquid is accumulated at the hair tip part at the left end of the hairbrush head is avoided, and after the liquid at the hair tip part is used, the liquid locked by the capillary grooves can be released onto the drainage rod through capillary imagination and then is smoothly guided to the hairbrush head by the drainage rod.
