In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection (such as snap connection, threaded connection, riveting), or a detachable connection, or an integral connection; of course, it can also be a mechanical connection or an electrical connection; in addition, it can also be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0039] The following are embodiments of the present application:

[0040] like Figure 1-18 As shown, a visual controlled-volume dropper bottle comprises an outer cover 1, a switch valve stem 2, a liquid storage chamber 3, a liquid outlet valve needle 4, an upper spring 5, a lower spring 6, a liquid storage chamber bottom support 7, an inner plug 8, a locking cover 9, and a bottle body 10. The liquid outlet valve needle 4 is integrally connected with the inner plug 8, and the upper and lower ends of the liquid storage chamber bottom support 7 are respectively integrally connected with the locking cover 9 and the liquid storage chamber 3; the lower end of the inner plug 8 is inserted into the bottle body 10, and the upper end of the inner plug 8 is inserted into the locking cover 9; an inner plug positioning groove 801 and a limiting hole 805 are provided on the inner plug 8, and an upper buckle position 902 and an anti-rotation rib 904 are provided on the locking cover 9, the inner plug positioning groove 801 is inserted into the locking cover 9 along the anti-rotation rib 904 and is fixed by being clamped by the upper buckle position 902, and the limiting hole 805 provided at the bottom of the inner plug 8 is connected with the limiting buckle 404 on the liquid outlet valve needle 4. A step hole 204 is provided in the switch valve stem 2, and the switch valve stem 2 is sleeved on the liquid outlet valve needle 2 through the step hole 204. A sliding pin 206 is provided at the lower part of the switch valve stem 2, and a cam groove 804 is provided on the inner plug. The sliding pin 206 can slide in the cam groove 804 when the liquid storage chamber 3 rotates. The liquid storage tank 3 and the inner plug 8 are not directly connected but can rotate relative to each other (that is, the liquid storage tank 3 rotates, but the inner plug 8 does not rotate therewith).

[0041] Furthermore, the upper spring 5 is sleeved on the upper end of the switch valve stem 2 and abuts against the liquid storage chamber 3, so that the switch valve stem 2 can stretch back and forth after being subjected to force; the lower spring 6 is sleeved on the liquid outlet valve needle 4 and is connected to the inner plug 8 as a whole, so that the liquid outlet valve needle 4 can stretch back and forth after being subjected to force.

[0042] Furthermore, a transmission positioning groove boss 704 and a second buckle position 703 are provided on the liquid storage chamber base 7, a connecting buckle position 901 is provided on the locking cover 9, and a first buckle position 304 is provided on the liquid storage chamber; the upper end of the liquid storage chamber base 7 is integrally connected with the liquid storage chamber 3 by buckling the first buckle position 304 with the transmission positioning groove boss 704; the lower end of the liquid storage chamber base 7 is integrally connected with the locking cover 9 by buckling the second buckle position 703 with the connecting buckle position 901.

[0043] Furthermore, a lower buckle position 903 is provided on the locking cover 9, a bottle mouth positioning groove 1001 and a third buckle position 1003 are provided on the bottle body 10, the anti-rotation rib 904 is fixedly connected to the bottle mouth positioning groove 1001, and the lower buckle position 903 and the third buckle position 1003 are fixedly connected. At the same time, since the sliding pin 206 provided on the switch valve stem 2 is connected to the cam groove 804 provided in the inner plug 8, the switch valve stem 2 will rotate and move up and down along the cam groove 804.

[0044] Furthermore, a sealing cylindrical surface 208 is provided at the upper end of the switch valve stem 2, which is sealed with the liquid outlet sealing rib 301 provided in the liquid storage chamber 3 when not in use.

[0045] Furthermore, a sealing piston 205 in the shape of an inverted trumpet is provided in the middle of the switch valve stem 2, which cooperates with the channel 701 provided on the liquid storage tank base 7 to control the opening and closing of the channel when in use.

[0046] Furthermore, the diameter of the liquid outlet valve needle piston 403 is larger than the diameter of the stepped through hole 204 provided inside the switch valve stem 2, thereby achieving the solution sealing effect through the interference fit between the stepped through hole 204 and the liquid outlet valve needle piston 403, while ensuring that the liquid outlet valve needle 4 slides back and forth smoothly.

[0047] Furthermore, the conical surface 402 provided at the upper end of the liquid outlet valve needle 4 cooperates with the sealing conical surface 209 provided on the switch valve stem 2 to seal, so that the liquid does not flow out by itself when not in use. At the same time, at least one liquid outlet groove 401 is provided at the head of the liquid outlet valve needle 4 to ensure that the liquid flows out smoothly when in use.

[0048] Furthermore, a spline 302 is provided on the liquid storage chamber 3 , and the spline 302 matches the spline groove 203 provided on the switch valve stem 2 in a concave-convex manner, so that the rotation of the liquid storage chamber 3 drives the switch valve stem 2 to rotate synchronously.

[0049] like Figure 2 As shown, when the dropper bottle is not in use, the sliding pin 206 of the switch valve stem 2 is located at the uppermost end of the cam groove 804 of the inner plug 8, and the upper spring 5 is in a compressed state. The sealing cylindrical surface 208 of the switch valve stem 2 and the sealing rib 301 of the liquid outlet of the liquid storage bin 3 are sealed, so that the liquid cannot flow out of the outlet 201. The sealing piston 205 of the switch valve stem 2 and the channel 701 set on the bottom support 7 of the liquid storage chamber are in an open state, and when the dropper bottle is inverted, the liquid in the bottle can flow into the liquid storage chamber 3 for storage.

[0050] like Figure 3 , 16As shown, when the user rotates the liquid storage chamber 3 by 90 degrees (counterclockwise or clockwise), the sliding pin 206 of the switch valve stem 2 is subjected to the tension of the upper spring 5 due to the rotation, and moves downward to the bottom along the cam groove 804 of the inner plug 8, and the upper spring 5 is in a relaxed state. The sealing cylindrical surface 209 of the switch valve stem 2 and the sealing rib 301 of the liquid outlet of the liquid storage chamber 3 are sealed, and the liquid can flow into the discharge channel 202 of the switch valve stem 2. The sealing piston 205 of the switch valve stem 2 and the channel 701 set by the liquid storage chamber bottom support 7 are closed, and the liquid flowing into the liquid storage chamber 3 can no longer flow back into the bottle, thereby completing the liquid storage and preparing for use. When the user uses the dropper bottle against the skin surface, the liquid outlet groove 401 of the liquid outlet valve needle 4 is pressed inward by the skin rebound force, and the liquid outlet valve needle piston 403 set by the liquid outlet valve needle 4 moves backward, pushing the lower spring 6 to compress and store energy. At the same time, the liquid outlet groove 401 of the liquid outlet valve needle 4 is connected to the discharge port 201 of the switch valve stem 2, and the liquid flows out to the skin surface along the liquid outlet groove 401. When the liquid outlet groove 401 of the liquid outlet valve needle 4 is separated from the skin surface, the liquid outlet valve needle 4 is pushed by the lower spring 6 to return to the initial state, and the conical surface 402 of the liquid outlet valve needle 4 contacts the sealing conical surface 210 of the switch valve stem 2, and the outflow channel is closed and no liquid is discharged, completing this precise amount control.

[0051] If the user needs to use it again, the user can rotate the liquid storage chamber 3 in the opposite direction (counterclockwise or clockwise) by 90 degrees to restore the switch valve stem 2 to the initial position, and then repeat the above operation, which will not be repeated here.

[0052] It should be noted that: in the present application, the rotation angle of the liquid storage chamber 3 can be set to any angle between 30 and 180 degrees, the shape of the sealing piston 205 can be set to various shapes such as an inverted trumpet shape, and the shape of the cam groove 804 can be set to various shapes such as a slope, and the present application does not make any special limitations on this.

[0053] The above embodiments are merely preferred embodiments of the present invention to illustrate the technical solution of the present invention, rather than limiting it, and certainly not limiting the patent scope of the present invention; ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention; that is to say, any changes or embellishments made to the main design concept and spirit of the present invention that have no substantive significance, and the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention; in addition, the direct or indirect application of the technical solution of the present invention in other related technical fields is also included in the patent protection scope of the present invention.
