[0040] The following are the embodiments of the present application:

[0041] Such as Figures 1-15As shown in the figure, an adjustable-dose dropper bottle includes a massage head 1, a liquid storage chamber cover 2, a lock cap 3, a driving cam 4, a pump base 5, a driven cam 6, a bottle body 7, a pump core 8, a straw 9, a spring 10. The pump base 5 is fixedly connected to the bottle body 7. A pump core sealing ring 506 is provided on the pump base 5. The pump core 8 is inserted into the pump base 5 and tightly fitted with the pump core sealing ring 506 to achieve a sealed connection. The massage head 1 is connected to the liquid storage chamber cover 2 with a clearance. A channel 105 is provided inside the massage head 1. The spring 10 is assembled inside the channel. One end of the spring 10 abuts against the lower end of the massage head 1, and the other end of the spring 10 abuts against the outside of the liquid outlet hole 301 provided on the lock cap 3. A connecting head 605 is provided on the driven cam 6. An anti-rotation guiding groove 501 is provided on the pump base 5. A pump core valve rod 801 is provided on the pump core 8. The driven cam 6 is assembled downward along the anti-rotation guiding groove 501 from top to bottom until the connecting head 605 and the pump core valve rod 801 are tightly fitted and connected. The driving cam 4 and the driven cam 6 are meshed with each other. An anti-rotation guiding groove 304 for the lock cap is provided on the lock cap 3. A positioning rib 401 is provided on the driving cam 4. The anti-rotation guiding groove 304 for the lock cap is pressed in along the direction of the positioning rib 401 (preferably the vertically downward direction) to achieve an interference fit between the lock cap 3 and the driving cam 4. The lock cap 3 is provided with a lock cap latching position 305, which catches the pump base step 505 provided in the pump base 5 to achieve the latching connection between the lock cap 3 and the pump base 5, thereby integrally assembling the pump core 8, the driving cam 4, the pump base 5, the driven cam 6, and the lock cap 3. A conical surface 206 of the liquid storage chamber cover is provided on the liquid storage chamber cover 2. A conical surface 109 of the massage head is provided on the massage head 1. The conical surface 206 of the liquid storage chamber cover and the conical surface 109 of the massage head are in contact in the initial state to achieve airtight sealing and prevent the paste from flowing out by itself when not in use. The liquid storage chamber cover 2 is provided with a connecting and sealing buckle 204 for the liquid storage chamber cover. The lock cap 3 is provided with a connecting and sealing buckle 303 for the lock cap. The sealing buckle 204 and the connecting and sealing buckle 303 for the lock cap are connected to form a liquid storage chamber for storing liquid.

[0042] Further, at least two driving cam guide rails 402 are provided on the driving cam 4 and are distributed centrally around the driving cam. The number of the driving cam guide rails 402 is inversely proportional to the rotation angle of the lock cap 3 each time. Since the total angle of one rotation is 360 degrees, when the number of the driving cam guide rails 402 is 4, 4 * the rotation angle of the lock cap 3 each time = 360 degrees, that is, the rotation angle of the lock cap 3 each time is 90 degrees. Preferably, 3 driving cam guide rails 402 are provided on the driving cam 4, and the rotation angle of the lock cap 3 each time is 120 degrees.

[0043] As Figure 15As shown in the figure, a liquid storage tank cover liquid level scale 205 is provided on the liquid storage tank cover 2, and the liquid discharge amount is the same each time the locking cover 3 rotates; for example, when there are 3 active cam guide rails 402 on the active cam 4, the rotation angle of the locking cover 3 each time is 120 degrees; the liquid discharge amount each time it rotates 120 degrees is 0.25 ml. Consumers can rotate different angles according to the liquid level line observed on the scale table, and the rotation angle each time is the same as the liquid discharge amount, so as to determine the usage amount suitable for themselves.

[0044] Furthermore, at least 2 guide ribs 202 are provided on the liquid storage tank cover 2. The guide ribs 202 are in clearance fit with the massage head 1. A connecting rod limit buckle 108 is provided on the massage head 1. A driven cam through-hole step 606 is provided on the driven cam 6. The position distance between the connecting rod limit buckle 108 and the driven cam through-hole step 606 is less than the position distance between the active cam 4 and the driven cam 6. Thus, when the locking cover 3 rotates, the locking cover 3 drives the active cam 4 to rotate. When the active cam 4 pushes the driven cam 6 to move downward to the lowest position, it can drive the massage head 1 to move downward in the clearance space between the guide ribs 202, so that the conical surface 206 of the liquid storage tank cover and the conical surface 109 of the massage head do not abut, and the air in the liquid storage cavity can be smoothly discharged to complete liquid storage.

[0045] Furthermore, a liquid discharge groove 101 is provided at the head of the massage head 1, which plays a role in discharging materials during use. At least 2 connecting ribs 102 are provided on the massage head. Liquid discharge channels 103 are formed between the respective connecting ribs 102. A connecting rod 106 is provided on the massage head 1. A liquid discharge groove 107 is provided on the connecting rod 106. A connecting rod limit buckle 108 is provided at the tail of the connecting rod 106. The liquid discharge groove 107 is sleeved in the discharge hole 601 provided on the driven cam 6 to jointly form a complete liquid discharge channel 103.

[0046] Furthermore, anti-rotation guide ribs 501 and pump seat retaining positions 503 are provided on the same pump seat 5. An anti-rotation positioning groove 702 and a bottle mouth retaining position 703 are provided in the bottle body 7. The anti-rotation guide ribs 501 on the pump seat are pressed into the bottle body along the anti-rotation positioning groove 702 of the bottle mouth until the pump seat retaining position 503 catches the bottle mouth retaining position 703, realizing the fixed connection between the pump seat 5 and the bottle body 7.

[0047] Furthermore, a driven cam sealing ring 602 is provided on the driven cam 6. The driven cam sealing ring 602 is in sealing cooperation with the locking cover channel 307 provided on the locking cover 3 and slides up and down relatively at the same time.

[0048] As Figure 2As shown in the figure, when the adjustable quantitative dropper bottle is not in use (initial state), the massage head conical surface 109 provided on the massage head 1 is sealed with the liquid storage chamber cover conical surface 206 provided on the liquid storage chamber cover 2 under the action of the spring 10 to achieve airtight sealing and prevent the paste from flowing out by itself when not in use; the driven cam 6 is engaged with the driving cam 4 under the action of the pump seat 5 and stays at the highest point during the up and down movement process.

[0049] As Figure 3 shown in the figure, when the adjustable quantitative dropper bottle stores liquid, when the driving cam 4 rotates a certain angle following the lock cap 3 and reaches the lowest point during the up and down movement process of the driving cam track 402, the driven cam 6 also moves up to the highest point of the stroke at the same time; meanwhile, the driven cam through-hole step 606 provided on the driven cam 6 drives the connecting rod limit buckle 108 provided on the massage head 1 to move the massage head 1 downward, resulting in the separation of the liquid storage chamber cover conical surface 206 and the massage head conical surface 109, exhausting the air in the liquid storage chamber, and the synchronous pump core 8 inhales the liquid and flows into the liquid storage cavity to complete one liquid storage.

[0050] As Figure 4 shown in the figure, for the use state of the adjustable quantitative dropper bottle, after the consumer rotates to different angles according to the liquid level line observed on the scale table, the massage head 1 retracts into the liquid storage chamber 2 under the action of an external force, and the liquid flows out from the liquid outlet groove 101 at 101 to complete the use.

[0051] The above embodiments are only relatively preferred embodiments of the present invention to illustrate the technical solutions of the present invention, rather than limiting it, and certainly not limiting the patent scope of the present invention; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; 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 modification or polishing that has no substantial meaning made on the main design concept and spirit of the present invention, and the technical problems solved by it are still the same as those of the present invention, should all be included within the protection scope of the present invention; in addition, directly or indirectly applying the technical solutions of the present invention to other related technical fields shall also be included within the patent protection scope of the present invention by the same token.
