Description

Technical Field

[0001] This utility model relates to the field of eye drop bottle technology, specifically to a liquid-blocking bottle. Background Technology

[0002] When using the liquid-blocking bottle, invert the bottle and press it to connect the inside and outside of the bottle, and the drops will drip out from the drip nozzle. When not in use, the liquid-blocking bottle is completely isolated from the outside, which can effectively seal and preserve the drops, making it convenient for users to use it repeatedly. Furthermore, when using the liquid-blocking bottle to drip the drops, the dosage of drops is fixed each time, avoiding waste.

[0003] Reference authorization announcement number CN221600655U, utility model entitled "Preservative-Free Drop Dispensing Pump Head and Dispensing Device", discloses "a preservative-free drop dispensing pump head, the preservative-free drop dispensing pump head including a pump cover, a pumping assembly, a first piston and a first spring. The pump cover has a dispensing channel on its top and a receiving cavity inside, which communicates with the dispensing channel. A drug inlet is opened on the side wall of the receiving cavity facing the dispensing channel. The pumping assembly is connected to the pump cover and is used to draw the medicine in the medicine bottle and pump it into the receiving cavity through the drug inlet. The first piston..." The device includes a base and a protrusion. The base is slidably disposed within a receiving cavity. The protrusion is connected to the base and is adapted to slide in and out of the dispensing channel with the base. After entering the dispensing channel, it seals with the dispensing channel to push out the liquid medicine within the dispensing channel. A first spring is disposed on the side of the base facing away from the protrusion, with one end connected to the base and the other end connected to the receiving cavity. This invention also provides a preservative-free drop-dose administration device, including a medicine bottle and the aforementioned pump head, which physically isolates the liquid medicine inside the bottle from the external environment, thus effectively preventing microbial contamination of the liquid medicine inside the bottle during repeated use without the need for preservatives.

[0004] Although the aforementioned authorized patent achieves the functions of pollution prevention and quantitative use, its liquid outlet channel, which consists of "suction port 411, pump channel 45, slot 121, guide channel 112, receiving cavity 122, flow channel 111 and outlet channel 114", is relatively tortuous and complex, resulting in poor liquid outlet stability.

[0005] Therefore, a liquid-blocking bottle needs to be designed to solve the above problems and stabilize the liquid output of the drops. Utility Model Content

[0006] The purpose of this invention is to design a liquid-blocking bottle to solve the problem of unstable liquid output from existing liquid-blocking bottles mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A liquid-blocking bottle includes a sealed liquid storage assembly, a guiding assembly, and a pumping assembly. The sealed liquid storage assembly includes a first channel with a movable switch. The guiding assembly includes a second channel that is sealed and connected to the first channel. The pumping assembly includes a third channel that is sealed and connected to the second channel, allowing it to move elastically. This third channel changes from a closed state to a connected state with the outside, thereby opening the switch in the first channel under negative pressure. The drops are then drawn into the vertical outlet chamber formed by the first channel, the second channel, and the third channel, and then... The pump assembly drips out; the pump assembly drives the third channel to move vertically, making the inside and outside of the liquid-blocking bottle connected. Under pressure, the movable switch in the first channel opens, allowing the drops in the sealed liquid storage assembly to be drawn into the vertical outlet chamber formed by the first, second, and third channels under negative pressure. During the dripping process, the linear movement of the third channel and the vertical design of the outlet chamber make the dripping path simple and clear, greatly reducing uncontrollable factors, thus facilitating subsequent quantitative dripping and improving the stability of the dripping volume.

[0009] Preferably, the sealed liquid storage assembly includes a liquid storage bottle filled with drops for sealing and storing the drops; the top of the liquid storage bottle is sealed with a tube, and a first channel is opened through the tube. A sealing ball is sealed and fitted to the bottom of the first channel extending into the liquid storage bottle. A ball groove adapted to the movement trajectory of the sealing ball is opened through the bottom of the first channel. As shown in the figure, a ball groove is provided at the bottom of the first channel, and the inner wall of the bottom end of the ball groove is sealed and fitted to the sealing ball. The inner diameter of the upper part of the ball groove is larger than the outer diameter of the sealing ball, and the inner diameter of the opening at the top of the ball groove is smaller than the outer diameter of the sealing ball, so that the sealing ball can move in the ball groove, thereby achieving the sealing and opening of the liquid storage bottle. The drops in the liquid storage bottle can then enter the ball groove and then enter the first channel.

[0010] Preferably, the guiding assembly includes a connecting tube that slides and seals with the insertion tube. The connecting tube is slidably and sealably connected inside the guiding tube, and the guiding tube is sealed and snapped onto the top outer surface of the liquid storage bottle. The second channel extends through the inside of the connecting tube and is sealed and connected to the first channel. The design of the second channel allows the drops entering the first channel to smoothly enter the second channel, thus enabling the movement of the drops.

[0011] Preferably, a first spring is connected between the connecting tube and the insertion tube. The design of the first spring allows the connecting tube to slide in a sealed state during operation, and to reset and seal under the action of the first spring after operation stops.

[0012] Preferably, the pump assembly includes a press cover that is slidably and sealingly connected to the guide tube; a clamping tube is slidably and sealingly connected inside the press cover, and a second spring is connected between the clamping tube and the press cover; the bottom of the clamping tube is sealed and engaged with the top of the connecting tube, the bottom of the clamping tube has a groove adapted to the shape of the top of the connecting tube, a connecting channel is opened through the inside of the clamping tube, and a protrusion for limiting the clamping tube is provided inside the guide tube; a piston tube is sealed and engaged with the top of the clamping tube, the top of the piston tube is sealed and engaged with the press cover, a third channel is opened through the inside of the piston tube, a through hole is opened at the upper end of the third channel, a drip outlet is opened at the top of the press cover, and a concave communicating groove is opened inside the press cover located below the drip outlet;

[0013] When the cap is pressed, the clamping tube moves first, which in turn moves the connecting tube. The moving connecting tube compresses the first spring until the clamping tube is stopped by the protrusion in the guide tube, at which point the clamping tube and the connecting tube stop moving downwards. When the cap is pressed again, the clamping tube remains stationary, compressing the second spring. At this time, the top of the piston tube gradually approaches the drip outlet at the top of the cap until the cap stops moving after being stopped by the clamping tube. At this point, the through hole in the piston tube aligns with the connecting groove, thus achieving communication between the inside and outside of the liquid-blocking bottle. Under pressure, the sealing ball is released, and the liquid in the storage bottle sequentially enters the ball groove, the first channel, the second channel, the connecting channel, the third channel, the connecting groove, and the drip outlet, finally completing the dripping operation.

[0014] Preferably, the pressing cover has a sliding groove that is slidably and sealingly connected to the card tube, and the second spring is located in the cavity between the top of the card tube and the top of the sliding groove; the distance between the top of the card tube and the top of the inner end of the sliding groove is equal to the distance between the through hole and the connecting groove, so that after the pressing cover moves the card tube and is limited by the protrusion, it can continue to move until the card tube stops moving after it abuts and is limited by the sliding groove, ensuring that the through hole in the piston tube can be aligned and connected with the connecting groove. The structure is reasonable and makes the entire dripping stroke simple and clear.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a vertical liquid outlet chamber formed by a ball groove, a first channel, a second channel, a connecting channel, and a third channel. When pressed with a pressing cap, the clamp tube and piston tube move relatively vertically and coaxially, making the dripping stroke simple and clear, and the movement distance clear, thereby improving the stability of the liquid output.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The embodiments of this utility model are as follows:

[0030] A liquid-blocking bottle, comprising a sealed liquid storage assembly 100, a guiding assembly 200, and a pumping assembly 300;

[0031] Reference Appendix Figure 1-3 It is understood that the sealed liquid storage assembly 100 includes a liquid storage bottle 110 filled with drops, and a tube 120 is sealed to the top of the liquid storage bottle 110. A first channel 121 is opened through the tube 120, and the bottom of the first channel 121 extends into the liquid storage bottle 110. A ball groove 122 is opened through the bottom of the first channel 121, and a sealing ball 130 is sealed and fitted to the bottom of the ball groove 122. The inner diameter of the upper part of the ball groove 122 is larger than the outer diameter of the sealing ball 130, and the inner diameter of the top opening of the ball groove 122 is smaller than the outer diameter of the sealing ball 130, so that the sealing ball 130 can move in the ball groove 122, thereby achieving the sealing and opening of the liquid storage bottle 110. After the sealing ball 130 is opened, the drops in the liquid storage bottle 110 first enter the ball groove 122, and then enter the first channel 121.

[0032] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 4 It is known that the guide assembly 200 includes a guide tube 210, which is sealed and snapped onto the top of the liquid storage bottle 110; a connecting tube 220 is slidably and sealed to the middle position of the guide tube 210, and the bottom of the connecting tube 220 is slidably and sealed to the top of the insertion tube 120. A first spring 140 is connected between the connecting tube 220 and the insertion tube 120. A second channel 221 is opened through the connecting tube 220, and the second channel 221 is sealed and connected to the first channel 121. Through the slidable and sealed connection between the connecting tube 220 and the insertion tube 210, and with the setting of the first spring 140, the connecting tube 220 moves down normally during use. After use, the restoring force of the first spring 140 causes the connecting tube 220 to return to its original position. The entire process always maintains a sealed connection, and the second channel 221 and the first channel 121 are always sealed and connected.

[0033] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 5It is known that the pump liquid assembly 300 includes a press cover 310, which is slidably sealed on the outer surface of the guide tube 210; a drip outlet 312 is provided at the top of the press cover 310, and a connecting groove 311 is provided inside the press cover 310 below the drip outlet 312. The connecting groove 311 is a circular groove that is recessed inward. A piston tube 330 is sealed and snapped inside the press cover 310 below the connecting groove 311. A third channel 331 is provided through the piston tube 330. A through hole 332 is provided on the inner wall of the top end of the third channel 331. The inner diameter of the through hole 332 is adapted to the outer diameter of the connecting groove 311.

[0034] The inside of the press cover 310 is provided with a sliding groove 313, which is connected to the third channel 331, and the bottom of the piston tube 330 extends into the sliding groove 313.

[0035] Inside the slide groove 313, a retaining tube 320 is elastically connected via a second spring 340. The retaining tube 320 is slidably and sealingly connected to the inner wall of the slide groove 313. The bottom of the piston tube 330 is sealed and engaged with the retaining tube 320, and the bottom of the retaining tube 320 is sealed and engaged with the top of the connecting tube 220. The bottom of the retaining tube 320 has a retaining groove 321 that matches the top of the connecting tube 220. Inside the guide tube 210, there is a protrusion 211 that mates with the retaining tube 320.

[0036] The tube 320 has a connecting channel 322 through it. The top of the connecting channel 322 is connected to the third channel 331, and the bottom of the connecting channel 322 is connected to the second channel.

[0037] The ball groove 122, the first channel 121, the second channel 221, the connecting channel 322, the third channel 331, the connecting groove 311, and the drip outlet 312 are all located on the same straight line, forming a vertical liquid storage chamber. In addition, the movement of the pressing cap 310, the clamping tube 320, and the connecting tube 220 are all vertical linear movements. Therefore, the entire dripping process is simple and clear, and the movement distance is clear, thereby improving the stability of the liquid output of the drops.

[0038] When needed, first invert the liquid-blocking bottle, then press the press cap 310. The press cap 310 will move the piston tube 330 and the clamping tube 320 together. The connecting tube 220 moves synchronously under the action of the clamping tube 320. At this time, the first spring 140 is gradually compressed until the clamping tube 320 is stopped by the protrusion 211 inside the guide tube 210. Continue pressing the press cap 310. After the clamping tube 320 stops moving, the piston tube 330 is also restricted from further movement. The press cap 310 then continues to move downwards until the top of the clamping tube 320 abuts against the top of the slide groove 313. At this time, the second spring 340 is compressed, and simultaneously, the top of the piston tube 330 moves with the press cap 310. As the piston moves closer to the connecting groove 311, until the top of the clamping tube 320 abuts against the top of the sliding groove 313 and the pressing cap 310 can no longer move, the through hole 332 on the piston tube 330 is aligned and connected with the connecting groove 311. At this time, the inside and outside of the liquid-blocking bottle are connected. Under the pressure formed, the sealing ball 130 will move in the ball groove 122, so that the drops inside the liquid storage bottle 110 are drawn into the ball groove 122, and then enter the third channel 331 in sequence along the first channel 121, the second channel 221 and the connecting channel 322. The drops that enter the third channel 331 will enter the connecting groove 311 along the through hole 332, and then drip out one drop at a time through the drip outlet 312 to complete the dripping operation.

[0039] After the operation is completed, the pressing cap 310 is released. At this time, under the restoring force of the first spring 140 and the second spring 340, the connecting tube 220, the clamping tube 320, and the pressing cap 310 gradually return to their original positions. At this time, the through hole 332 on the piston tube 330 also disengages from the connecting groove 311 and completes the sealing again. At the same time, the sealing ball 130 will also return to its original position to seal the liquid storage bottle 110 for easy use next time.
