Abstract
Description
[0001] This application is a divisional application of application number 202110344721.4, filed on 2021-3-29, concerning a liquid dispensing device. Technical Field
[0002] This invention relates to a liquid dispensing device. Background Technology
[0003] In the food, chemical, and biological fields, some containers are used to hold substances. When these substances are needed, the container needs to be squeezed to expel the substances from it. However, the amount of substances expelled by this squeezing method is not fixed and needs to be determined by the user. Therefore, there may be a large error in expelling substances, resulting in waste.
[0004] Moreover, this squeezing method of dispensing liquid will also leave some residue on the inner wall of the container, and the substance cannot be completely discharged. When there is little substance in the container, it is necessary to turn the container upside down and wait for the substance to flow from the bottom to the mouth of the container before squeezing the container again to make the substance flow out. This is inconvenient to use. In addition, the substance adsorbed on the container wall not only causes some waste, but also affects the secondary use of the container.
[0005] This invention was developed based on the aforementioned shortcomings. Summary of the Invention

[0019] The base and the extrusion piece are fitted together to form an air intake chamber, and the base is provided with a communication port for connecting the air intake chamber with the outside air.
[0020] The driving component includes multiple ribs, one end of which is connected to the base and the other end to the extruder, which can rotate with the base and pull the extruder relative to the container when the base rotates relative to the container.
[0021] The driving component includes multiple ribs, one end of which is connected to the base and the other end to the extruder, which can rotate with the base and pull the extruder relative to the container when the base rotates relative to the container.
[0022] The extrusion component and the base are fitted together to form an air intake chamber. An air intake pipe is provided between the extrusion component and the base.

The base also has a fourth air intake port that can connect the ventilation channel with the outside air. The air intake pipe is a flexible hose.
[0023] The base is provided with a fixing part that can fix the upper end of the rib.
[0024] The driving component includes a rib connecting seat connected to the base and capable of moving with the base.

[0030] 1. In use, the liquid dispensing device of this invention rotates the base, causing the base to drive the driving component to rotate. As the driving component rotates with the base, it drives the extruder to move upward relative to the container, thus squeezing the substance inside the container out of the container's receiving cavity through the dispensing port. It is very convenient to use, as there is no need to squeeze the container forcefully; liquid dispensing can be achieved simply by rotating the base. Furthermore, when it is necessary to continuously remove the substance from the receiving cavity, it is only necessary to continuously rotate the base to continuously dispense the liquid. The container can be a transparent bottle with a scale, etc. By rotating the base, the extruder can be moved to a fixed scale position, thus achieving quantitative dispensing of the substance from the receiving cavity. The liquid dispensing accuracy is high, and there is no waste due to excessive dispensing.
[0031] 2.

[0058] The present invention will now be further described with reference to the accompanying drawings: Example
[0059] like Figures 1 to 7As shown, the present invention provides a liquid dispensing device, including a container 1 and a base 2 movably connected to the container 1. The base 2 and the container 1 cooperate to form a receiving cavity 300 capable of storing substances. A squeezing member 4 that can move relative to the container 1 is connected inside the container 1. A driving member 5 that can drive the squeezing member 4 to move relative to the container 1 and squeeze the substances outward when the base 2 is operated is connected to the base 2. The base 2 is provided with an outlet 21 for discharging the substances in the receiving cavity 300 outward.
[0060] In use, the liquid dispensing device of this invention involves rotating the base 2, which in turn drives the driving component 5 to rotate. As the driving component 5 rotates with the base 2, it drives the extrusion component 4 to move upwards relative to the container 1, extruding the substance inside the container 1 from its receiving cavity 300 through the outlet 21. This method is very convenient, requiring no forceful squeezing of the container 1; simply rotating the base 2 is sufficient for dispensing. Furthermore, when continuous dispensing of the substance from the receiving cavity 300 is required, continuous rotation of the base 2 ensures a continuous outflow of liquid. The container 1 can be a transparent bottle with a graduated scale; rotating the base 2 moves the extrusion component 4 to a fixed graduated position, allowing for the quantitative dispensing of the substance from the receiving cavity 300. The dispensing accuracy is high, preventing waste due to excessive dispensing. The substances include liquids, sauces, viscous substances, and powders, all of which can be quantitatively dispensed. This liquid dispensing device can be applied not only to the food industry but also to the biological and chemical fields for the quantitative dispensing of specific substances.
[0061] like Figures 1 to 4 As shown, the base 2 and the extrusion member 4 cooperate to form an air intake cavity 600, and the drive member 5 is provided with an air intake channel 511 for connecting the air intake cavity 600 with the external atmosphere.
[0062] like Figures 1 to 4 and Figure 7As shown, the driving component 5 includes a column 51 with one end movably connected to the bottom of the container 1 and the other end connected to the base 2. An air intake channel 511 is provided on the column 51. The container 1 is also provided with a positioning column 11 movably connected to the lower end of the column 51. The positioning column 11 has a first air inlet 111 connecting the air intake channel 511 and the air intake chamber 600. The base 2 also has a second air inlet 22 connecting the air intake channel 511 and external air. External air enters the air intake channel 511 from the outside through the second air inlet 22 on the base 2, and then enters the air intake chamber 600 through the first air inlet 111 on the positioning column 11 to replenish air to the container 1. This avoids the problem of having to wait for the container to recover after being squeezed before squeezing it again, thus improving the efficiency of liquid discharge. The upper end of the column 51 is fixed to the base 2 and can rotate with the base 2, while the lower end of the column 51 is rotatably connected to the positioning column 11.
[0063] like Figures 1 to 4 and Figure 6 As shown, the column 51 is also provided with a first thread 512, the extrusion member 4 is sleeved on the column 51, and the extrusion member 4 is also provided with a second thread 41 that can cooperate with the first thread 512 on the column 51 when the column 51 moves, so that the extrusion member 4 moves relative to the container 1.
[0064] When the base 2 is rotated, it causes the column 51 to rotate clockwise relative to the container 1. At this time, the first thread 512 on the column 51 engages with the second thread 41 on the extruder 4, allowing the extruder 4 to rotate counterclockwise relative to the column 51, thereby moving upward relative to the base 2 and extruding the material in the receiving cavity 300 outward. This is very convenient to use; simply rotating the base 2 continuously extrudes the material. Furthermore, since the pitch of the first thread 512 and the second thread 41 is fixed, the distance the extruder 4 can move upward when the base 2 rotates one revolution is also fixed. Therefore, the number of revolutions of the base 2 can be used to achieve quantitative liquid dispensing, which is very convenient. Moreover, the pitch of the first thread 512 and the second thread 41 can be finely adjusted according to the scale on the container 1, making the liquid dispensing more accurate.
[0065] like Figures 1 to 4 As shown, the base 2 is also provided with a positioning groove 23 for accommodating the upper end of the column 51 and for driving the column 51 to rotate when the base 2 rotates relative to the container 1. The second air inlet 22 is located at the upper end of the positioning groove 23. The upper end of the column 51 is fixed by the positioning groove 23 to prevent the column 51 from not rotating with the base 2 when the base 2 rotates, thus preventing the extruder 4 from being unable to be driven.
[0066] like Figures 1 to 4As shown, the column 51 is also provided with a stop 513 for limiting the sliding position of the extruder 4. The stop 513 is used to limit the stroke of the extruder 4.
[0067] A sealing ring 6 is also provided between the extruder 4 and the column 51. The sealing ring 6 can increase the sealing performance between the extruder 4 and the column 51. The extruder 4 is a piston, which can scrape the material on the inner wall of the container 1 clean when it moves upward relative to the container 1, avoiding waste and enabling the container 1 to be reused, which is more environmentally friendly. Among the above-mentioned substances, pastes and viscous substances are more difficult to discharge from outside the container 1. The effect of liquid discharge is best when the piston is used to squeeze outward. Moreover, the piston can also scrape the residue on the inner wall of the container clean, avoiding residue.
[0068] like Figures 1 to 4 As shown, the outer wall of the outlet 21 is provided with a tearable first sealing sheet 211, and the outer wall of the second air inlet 22 is provided with a tearable second sealing sheet 221. A first pull ring 212 is provided between the first sealing sheet 211 and the second sealing sheet 221, which can pull them together. By pulling the first pull ring 212, the first sealing sheet 211 and the second sealing sheet 221 can be pulled out, making them more convenient to use.
[0069] like Figures 1 to 4 As shown, the base 2 is also provided with a buckle 24, and the container 1 is provided with a buckle groove 12 that can engage with the buckle 24 to allow the base 2 to rotate relative to the container 1. The base 2 is rotatably connected to the container 1 through the engagement of the buckle 24 and the buckle groove 12.
[0070] like Figures 1 to 5 As shown, the base 2 is also provided with a flip cover 8 that can be closed on it. When the liquid dispensing device is in use, the flip cover 8 is closed to prevent external air or impurities from entering the receiving cavity 300 and contaminating the substances in the receiving cavity 300.
[0071] like Figure 5 As shown, a tearable anti-counterfeiting component 81 is also provided between the base 2 and the flip cover 8. The anti-counterfeiting component 81 is used to prevent counterfeits. Example
[0072] like Figures 8 to 9 As shown, the difference between this embodiment and embodiment 1 is that the driving component 5 includes a column 51 with one end movably connected to the bottom of the container 1 and the other end connected to the base 2. The column 51 is provided with a liquid outlet channel 514 for connecting the receiving cavity 300 and the outlet 21. The container 1 is also provided with a support column 15 that can be movably connected to the lower end of the column 51, and the support column 15 is provided with a liquid inlet 151 that can connect the liquid outlet channel 514 and the receiving cavity 300.
[0073] like Figures 8 to 9 As shown, the column 51 is also provided with a first thread 512, the extrusion member 4 is sleeved on the column 51, and the extrusion member 4 is also provided with a second thread 41 that can cooperate with the first thread 512 on the column 51 when the column 51 moves, so that the extrusion member 4 moves relative to the container 1. The second thread 41 is set in the opposite direction to the second thread 41 in Embodiment 1, so that the extrusion member 4 in this embodiment moves downward relative to the container 1.
[0074] When the base 2 is rotated, it causes the column 51 to rotate clockwise relative to the container 1. At this time, the first thread 512 on the column 51 engages with the second thread 41 on the extruder 4, allowing the extruder 4 to rotate clockwise relative to the column 51 and move downward relative to the base 2. This extrudes the material in the receiving cavity 300 to the inlet 151. After passing through the inlet 151, the material is poured out from the outlet 21. This is very convenient to use; simply rotating the base 2 continuously extrudes the material. Furthermore, since the pitch of the first thread 512 and the second thread 41 is fixed, the distance the extruder 4 can move upward when the base 2 rotates one revolution is also fixed. Therefore, a quantitative dispensing can be achieved by rotating the base 2 a certain number of times, which is very convenient.
[0075] like Figures 8 to 9 As shown, the base 2 is also provided with a fixing groove 25 for accommodating the upper end of the column 51 and for driving the column 51 to rotate when the base 2 rotates relative to the container 1. The outlet 21 is located at the upper end of the fixing groove 25. The upper end of the column 51 is fixed by the fixing groove 25 to prevent the column 51 from not rotating with the base 2 when the base 2 rotates, thus preventing the extruder 4 from being unable to be driven.
[0076] like Figures 8 to 9 As shown, the base 2 and the extrusion member 4 cooperate to form an air intake chamber 600, and the base 2 is provided with a communication port 26 for connecting the air intake chamber 600 with the outside air. The communication port 26 is used to replenish air to the air intake chamber 600.
[0077] like Figures 8 to 9 As shown, the outer wall of the outlet 21 is provided with a tearable third sealing sheet 213, and the third sealing sheet 213 is provided with a second pull ring 214. The outer wall of the connecting port 26 is provided with a tearable fourth sealing post 261. Before use, the third sealing sheet 213 and the fourth sealing post 261 need to be removed to keep the liquid outlet channel 514 unobstructed from the outside, and allow outside air to enter the air inlet chamber 600 through the connecting port 26. Example
[0078] like Figures 10 to 11As shown, the difference between this embodiment and embodiment 1 is that the driving component 5 includes a plurality of ribs 52, one end of which is connected to the base 2 and the other end of which is connected to the extruder 4, and which can rotate with the base 2 when the base 2 rotates relative to the container 1, thereby pulling the extruder 4 to move relative to the container 1.
[0079] When the base 2 is rotated, it causes the column 51 to rotate clockwise relative to the container 1. At this time, the ribs 52 on the base 2 rotate with it, winding around the column 51. As the ribs 52 shorten, the extruder 4 connected to their lower ends moves upwards, allowing the material in the receiving cavity 300 to be extruded from the outlet 21 by the extruder 4. Continuous rotation of the base 2 is sufficient to continuously discharge material. Furthermore, the ribs 52, extruder 4, and base 2 can be integrally injection molded, making processing easier and saving production costs. Example
[0080] like Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that the base 2 is provided with a fixing part 28 that can fix the upper end of the rib 52. The upper end of the rib 52 can be removed from the fixing part 28, which facilitates the replacement of the extrusion piece 4 and the rib 52. Example
[0081] like Figures 13 to 14 As shown, the difference between this embodiment and embodiment 3 is that the driving component 5 includes a plurality of ribs 52, one end of which is connected to the base 2 and the other end of which is connected to the extruder 4, and which can rotate with the base 2 when the base 2 rotates relative to the container 1, thereby pulling the extruder 4 to move relative to the container 1.
[0082] When the base 2 is rotated, it causes the column 51 to rotate clockwise relative to the container 1. At this time, the ribs 52 on the base 2 rotate with it, winding around the column 51. As the ribs 52 shorten, the extruder 4 connected to their lower ends moves upwards, allowing the material in the receiving cavity 300 to be extruded from the outlet 21 by the extruder 4. Continuous rotation of the base 2 is sufficient to continuously discharge material. Furthermore, the ribs 52, extruder 4, and base 2 can be integrally injection molded, making processing easier and saving production costs.
[0083] like Figures 13 to 14As shown, the extrusion member 4 and the base 2 cooperate to form an air intake chamber 600. An air intake pipe 7 is provided between the extrusion member 4 and the base 2. The air intake pipe 7 has a ventilation channel 71 that connects the air intake chamber 600 to the outside atmosphere. The extrusion member 4 has a third air inlet 42 that connects the ventilation channel 71 to the air intake chamber 600. The base 2 also has a fourth air inlet 27 that connects the ventilation channel 71 to the outside air. The air intake pipe 7 is a flexible hose. The air intake pipe 7 is used to replenish air to the air intake chamber 600. Because the air intake pipe 7 is a flexible hose, it will also rotate and shorten its distance when the base 2 rotates.
[0084] like Figures 13 to 14 As shown, the outer wall of the outlet 21 is provided with a tearable fourth sealing sheet 215, the third sealing sheet 213 is provided with a second pull ring 216, and the outer wall of the fourth air inlet 27 is provided with a tearable fifth sealing post 271. The liquid dispensing device can only be used after the fourth sealing sheet 215 and the fifth sealing post 271 have been removed. Example
[0085] like Figure 15 As shown, the difference between this embodiment and embodiment 3 is that the base 2 is provided with a fixing part 28 that can fix the upper end of the rib 52. The upper end of the rib 52 can be removed from the fixing part 28, which facilitates the replacement of the extrusion piece 4 and the rib 52. Example
[0086] like Figure 16 As shown, the difference between this embodiment and Embodiment 5 is that the container 1 is equipped with an intake valve 13 that connects the intake chamber 600 to the outside atmosphere when opened. A sealing cap 14, capable of closing the intake valve 13, is also detachably connected to the container 1. When the intake valve 13 is open, external gas can enter the intake chamber 600 from the bottom of the container 1 for replenishment, and the sealing cap 14 closes the intake valve 13, thereby preventing external air from entering the intake chamber 600. The intake valve 13 and the intake pipe 7 work together to simultaneously replenish the intake chamber 600, improving the efficiency of gas replenishment. Example
[0087] like Figure 17As shown, the difference between this embodiment and Embodiment 6 is that the container 1 is equipped with an intake valve 13 that connects the intake chamber 600 to the outside atmosphere when opened. A sealing cap 14, capable of closing the intake valve 13, is also detachably connected to the container 1. When the intake valve 13 is open, external gas can enter the intake chamber 600 from the bottom of the container 1 for replenishment, and the sealing cap 14 closes the intake valve 13, thereby preventing external air from entering the intake chamber 600. The intake valve 13 and the intake pipe 7 work together to simultaneously replenish the intake chamber 600, improving the efficiency of gas replenishment. Example
[0088] like Figures 18 to 19 As shown, the difference between this embodiment and embodiment 5 is that the driving component 5 includes a rib connecting seat 54 connected to the base 2 and capable of moving with the base 2. Multiple annular connecting ribs 53 are connected between the rib connecting seat 54 and the extruder 4, which, when the base 2 rotates relative to the container 1, can rotate with the base 2 and pull the extruder 4 upward relative to the container 1. The rib connecting seat 54 is provided with an inlet 541 communicating with the outlet. The annular connecting ribs 53 have good strength, and when the extruder 4 moves upward to contact the rib connecting seat 54, the bottom surface of the rib connecting seat 54 can limit the movement stroke of the extruder 4.
[0089] The container 1 is equipped with an intake valve 13 that connects the intake chamber 600 to the outside atmosphere when opened. A sealing cap 14, capable of closing the intake valve 13, is also detachably connected to the container 1. When the intake valve 13 is open, outside air can enter the intake chamber 600 from the bottom of the container 1 to replenish the air supply, and the sealing cap 14 closes the intake valve 13, thereby preventing outside air from entering the intake chamber 600.
[0090] The outer wall of the outlet 21 is provided with a tearable sixth sealing sheet 217, and the third sealing sheet 213 is provided with a third pull ring 218. Before using this device, the sixth sealing sheet 217 needs to be removed from the base 2.
[0091] Example 10:
[0092] like Figures 20 to 26 As shown, the difference between this embodiment and Embodiment 2 is that a linkage 91 is also provided between the extruder 4 and the column 51, which can drive the extruder 4 to slide relative to the container 1 when the column 51 rotates. The column 51 is polygonal, and the linkage 91 is sleeved on the column 51. The extruder 4 is sleeved outside the linkage 91, and the upper end of the extruder 4 is also provided with an elastic pressing member 92 that presses against the linkage 91 when the extruder 4 slides.
[0093] When the base 2 is rotated, the base 2 drives the column 51 to rotate clockwise relative to the container 1. Since the column 51 is polygonal, it can engage with the linkage 91 after rotating a certain arc relative to the linkage 91. At this time, the linkage 91 follows the rotation of the column 51, thereby pushing the extruder 4 to move downward relative to the column 51, squeezing the material in the receiving cavity 300 to the liquid inlet 151. After the material passes through the liquid inlet 151, it is poured out from the outlet 21. It is very convenient to use; simply rotating the base 2 continuously squeezes the material outward. Furthermore, when the linkage 91 presses the extruder 4 down a certain distance, it rotates a certain distance relative to the column 51. At this time, the linkage 91 and the column 51 move from an engaged state to a more relaxed state. At this time, the elastic pressing member 92 connected to the linkage 91 can pull the linkage 91 down a certain distance through elastic force. Then, rotating the base 2 again causes the column 51 and the linkage 91 to engage again. Repeating the above steps allows for continuous liquid discharge.
[0094] like Figures 20 to 26 As shown, the extruder 4 is provided with a second inclined sliding surface 43, and the linkage 91 is provided with a third inclined sliding surface 911 that can press against the second inclined sliding surface 43 during movement. When the linkage 91 rotates, the third inclined sliding surface 911 on the linkage 91 abuts against the second inclined sliding surface 43 on the extruder 4, causing the extruder 4 to slide downward relative to the column 51. Since the height of the third inclined sliding surface 911 is fixed, the distance by which the linkage 91 presses against the extruder 4 and moves downward when the base 2 rotates one revolution is also fixed. Therefore, quantitative liquid dispensing can be achieved by controlling the number of revolutions of the rotating base 2, which is very convenient.
[0095] like Figures 20 to 26 As shown, the column 51 is also provided with an inverted buckle 515. The inverted buckle 515 has a first inclined sliding surface 5151 that allows the linkage member 91 to slide, and the inverted buckle 515 also has a stop surface 5152 that can prevent the elastic pressing member 92 from resetting in the opposite direction. The first inclined sliding surface 5151 on the inverted buckle 515 makes the linkage member 91 slide more smoothly relative to the column 51, while the stop surface 5152 is used to prevent the elastic pressing member 92 from resetting in the opposite direction.
