Abstract
Description
Technical Field
[0001] This utility model relates to the field of bubble water device technology, and in particular to a bubble enhancement structure and a bubble water device. Background Technology
[0002] Sparkling water is water containing dissolved carbon dioxide (CO2), offering a refreshing taste and a slightly bubbly sensation. Typically, to drink sparkling water, it needs to be forced out of a sparkling device (such as a carbonation tank with a dispensing valve) using food-grade carbon dioxide pressure. As the pressure decreases during expulsion, the water creates bubbles. However, existing sparkling devices sometimes produce sparkling water with such high flow rates and strong impacts that carbon dioxide overflows, resulting in a poor taste.
[0003] Therefore, there is an urgent need to propose a bubble-enhancing structure and a bubble water device to solve the above problems. Utility Model Content
[0004] The first objective of this invention is to provide a bubble-enhancing structure that can both stimulate the carbon dioxide in sparkling water to generate more bubbles and regulate the outflow speed of sparkling water to prevent carbon dioxide from overflowing and reducing the number of bubbles, thereby improving the taste of sparkling water.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A bubble-enhancing structure, which can be installed at the outlet of a container for holding sparkling water, the bubble-enhancing structure comprising:
[0007] The first cylinder has a first outlet at one end along the axial direction;
[0008] An end cap is provided to seal the opening at one end of the first cylinder away from the first outlet. The end cap is provided with a first through hole and a second through hole that are interconnected. The first through hole is connected to the outlet of the container.
[0009] The second cylinder is connected to the first cylinder from the inside to the outside. The end of the second cylinder away from the end cap is provided with a second outlet, and the size of the second outlet is larger than the size of the first outlet.
[0010] The reinforcing shaft includes a shaft body and a reinforcing block. One end of the shaft body is connected to the reinforcing block, and the other end is movably located in the second cylinder and opposite to the first outlet and the second outlet. The reinforcing block is movably located in the second through hole and can abut against the opening edge of the second cylinder. A gap is left between the side wall of the reinforcing block and the inner wall of the second through hole. The gap is connected to the second cylinder. The bubble water entering the second through hole can generate bubbles by exciting the carbon dioxide in the bubble water through the gap. The bubble water flowing from the second outlet to the first outlet can generate a reverse force to push the reinforcing shaft to move closer to the end cap.
[0011] As an optional technical solution for the bubble reinforcement structure, the outer wall of the end cap is recessed with a snap-fit groove, the snap-fit groove extends circumferentially along the end cap and is arranged in a closed loop, and the inner wall of the first cylinder and the end facing the end cap abut against the inner wall of the snap-fit groove.
[0012] As an optional technical solution for the bubble-reinforced structure, the inner wall of the first cylinder is provided with an internal thread, and the inner wall of the snap-fit groove is provided with an external thread. The first cylinder and the end cap are connected by the internal thread and the external thread.
[0013] As an optional technical solution for the bubble reinforcement structure, the inner wall of the first cylinder opening towards the end cap is provided with a first annular groove, and the inner wall of the snap-fit groove is provided with a second annular groove. The second annular groove and the first annular groove are opposite to each other along the radial direction of the first cylinder. The bubble reinforcement structure also includes a sealing ring, which is located in the first annular groove and the second annular groove and abuts against the end cap and the first cylinder.
[0014] As an optional technical solution for the bubble-reinforced structure, the radial dimension of the gap along the second through hole is 0.05 mm.
[0015] As an optional technical solution for bubble-reinforced structures, the second cylinder is connected to the first cylinder by an interference fit.
[0016] As an optional technical solution for the bubble-reinforced structure, the outer wall of the shaft body is clearance-fitted with the inner wall of the second cylinder.
[0017] As an optional technical solution for the bubble reinforcement structure, the second cylinder has an annular boss at one end facing the end cap, and the outer diameter of the annular boss is smaller than the outer diameter of the second cylinder, and the inner diameter of the annular boss is smaller than the inner diameter of the second cylinder. The shaft body passes through the inner ring of the annular boss and the second cylinder in sequence, and the end of the annular boss facing the end cap abuts against the reinforcing block.
[0018] As an optional technical solution for the bubble-reinforced structure, the outer side of the annular boss is provided with a groove, which extends along the axial direction of the second cylinder to the inner wall of the second cylinder.
[0019] The second objective of this invention is to provide a sparkling water device that can enhance the bubbles in the extruded sparkling water to improve its taste.
[0020] To achieve this objective, the present invention adopts the following technical solution:
[0021] A sparkling water device includes a container and the aforementioned bubble-enhancing structure. The container is used to hold sparkling water, and the bubble-enhancing structure can be installed at the outlet of the container. The outlet is connected to the first through hole.
[0022] The beneficial effects of this utility model are:
[0023] The bubble-enhancing structure provided by this utility model can be installed at the outlet of a container, and includes a first cylinder, an end cap, a second cylinder, and a reinforcing shaft. The end cap seals the first cylinder, and the second cylinder is sleeved and connected to the first cylinder. The first through hole of the end cap communicates with the outlet of the container, allowing bubble-filled water in the container to enter the bubble-enhancing structure through the first through hole. The reinforcing shaft includes a shaft body and a reinforcing block. The shaft body is movably located in the second cylinder, and the reinforcing block is movably located within the second through hole, allowing the reinforcing block to slide within the second through hole and the shaft body to slide within the second cylinder. The reinforcing block can abut against the opening edge of the second cylinder to prevent the reinforcing block from dislodging from the second through hole. A gap exists between the sidewall of the reinforcing block and the inner wall of the second through hole. Sparkling water entering the second through hole can further stimulate the release of carbon dioxide by flowing through this gap, thus generating more bubbles. Since the radial dimension of the first outlet is smaller than that of the second outlet, sparkling water flowing from the second outlet to the first outlet experiences a reaction force due to the smaller outlet size. This force pushes the reinforcing shaft closer to the end cap, reducing the axial dimensions of the reinforcing shaft and end cap along the first cylinder. This reduces the flow rate of the sparkling water, preventing excessive flow velocity and impact that could lead to carbon dioxide overflow, resulting in fewer or even no bubbles. Therefore, the bubble-reinforcing structure not only further stimulates the release of carbon dioxide in the sparkling water to generate more bubbles but also regulates the flow rate of the sparkling water, preventing carbon dioxide overflow and bubble reduction due to excessive flow velocity and impact, thereby improving the taste of the sparkling water.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0037] This embodiment provides a bubble-enhancing structure that can both stimulate the carbon dioxide in sparkling water to generate more bubbles and regulate the outflow speed of sparkling water to prevent carbon dioxide from overflowing and reducing the number of bubbles, thereby improving the taste of sparkling water.
[0038] Specifically, such as Figure 1 and Figure 2As shown, this bubble-enhancing structure can be installed at the outlet of a container used to hold sparkling water (water with dissolved carbon dioxide). The bubble-enhancing structure includes a first cylinder 100, an end cap 200, a second cylinder 300, and a reinforcing shaft 400. One axial end of the first cylinder 100 has a first outlet 110. The end cap 200 seals the opening of the first cylinder 100 away from the first outlet 110. The end cap 200 has a first through hole 210 and a second through hole 220 that communicate with each other. The first through hole 210 communicates with the outlet of the container. The second cylinder 300 is connected to the first cylinder 100 from the inside out. The end of the second cylinder 300 away from the end cap 200 has a second outlet 310, and the size of the second outlet 310 is larger than the size of the first outlet 110. The reinforcing shaft 400 includes a shaft body 410 and a reinforcing block 420. One end of the shaft body 410 is connected to the reinforcing block 420, and the other end is movably located in the second cylinder 300 and is opposite to the first outlet 110 and the second outlet 310. The reinforcing block 420 is movably located in the second through hole 220 and can abut against the opening edge of the second cylinder 300. In this embodiment, the radial dimension of the reinforcing block 420 is larger than the radial dimension of the shaft body 410. A gap 401 is left between the side wall of the reinforcing block 420 and the inner wall of the second through hole 220, and the gap 401 is connected to the second cylinder 300. That is, the bubble water can flow sequentially through the first through hole 210, the second through hole 220, the gap 401 and the second cylinder 300, and then flow out sequentially from the second outlet 310 and the first outlet 110. In the above process, the bubble water entering the second through hole 220 can generate more bubbles by further stimulating the carbon dioxide in the bubble water through the gap 401; the bubble water flowing from the second outlet 310 to the first outlet 110 can generate a reaction force to push the reinforcing shaft 400 to move closer to the end cap 200, so as to control the flow rate of the bubble water.
[0039] Based on the above design, the end cap 200 is sealed to the first cylinder 100, and the second cylinder 300 is sleeved and connected to the first cylinder 100. The first through hole 210 of the end cap 200 is connected to the outlet of the container, allowing the bubble-reinforced water in the container to enter the bubble-reinforced structure through the first through hole 210. The shaft body 410 is movably located in the second cylinder 300, and the reinforcing block 420 is movably located in the second through hole 220, allowing the reinforcing block 420 to slide within the second through hole 220 and the shaft body 410 to slide within the second cylinder 300. The reinforcing block 420 can abut against the opening edge of the second cylinder 300 to prevent the reinforcing block 420 from dislodging from the second through hole 220. A gap 401 is left between the side wall of the reinforcing block 420 and the inner wall of the second through hole 220. Sparkling water entering the second through hole 220 can further stimulate the release of carbon dioxide by flowing through the gap 401, thus generating more bubbles. Since the radial dimension of the first outlet 110 is smaller than that of the second outlet 310, the sparkling water flowing from the second outlet 310 to the first outlet 110 will generate a reverse force due to the smaller outlet size, pushing the reinforcing shaft 400 towards the end cap 200. This reduces the axial dimensions of the reinforcing shaft 400 and the end cap 200 along the first cylinder 100, thereby reducing the flow rate of the sparkling water and preventing excessive flow velocity and impact force that could lead to carbon dioxide overflow, resulting in fewer or even no bubbles. Therefore, the bubble-enhancing structure can both further stimulate the release of carbon dioxide in the sparkling water to generate more bubbles and regulate the flow rate of the sparkling water, preventing carbon dioxide overflow and bubble reduction due to excessive flow velocity and impact force, thus improving the taste of the sparkling water.
[0040] The specific process of bubble generation is as follows: Bubble water (water containing dissolved carbon dioxide) enters the first through-hole 210 through the outlet of the container. A significant pressure difference exists between the first through-hole 210 and the container. According to Henry's Law, a decrease in pressure leads to a decrease in the solubility of carbon dioxide, causing some of the dissolved carbon dioxide to rapidly precipitate from the bubble water, forming tiny bubbles. The bubble water then enters the second through-hole 220 from the first through-hole 210. When the bubble water carrying some bubbles flows through the narrow space of the gap 401, its speed increases, and the local pressure further decreases (Bernoulli's principle), prompting more carbon dioxide bubbles to precipitate. The bubble water entering the second cylinder 300 flows through the second outlet 310 into the first outlet 110. The smaller outlet size of the bubble water generates a reverse force, causing the reinforcing block 420 to move towards the end cap 200. As the space for bubble water in the second through hole 220 decreases, the flow rate of the bubble water decreases, preventing the bubble water from overflowing due to excessive impact force caused by excessive flow rate, thus reducing the number of bubbles. In other words, the second cylinder 300 and the reinforcing shaft 400 can automatically adjust the flow rate of the bubble water, thereby ensuring that the final amount of bubbles generated in the bubble water flowing out of the first outlet 110 is large.
[0041] In this embodiment, the end cap 200, the first cylinder 100, the second cylinder 300 and the reinforcing shaft 400 are all coaxially arranged, and the first through hole 210, the second through hole 220, the second outlet 310 and the first outlet 110 are all arranged opposite each other.
[0042] Optionally, such as Figure 3 and Figure 4 As shown, the outer wall of the end cap 200 is recessed with a snap-fit groove 230. The snap-fit groove 230 extends circumferentially along the end cap 200 and is arranged in a closed loop. The inner wall of the first cylinder 100 and the end facing the end cap 200 abut against the inner wall of the snap-fit groove 230. That is, at least a part of the end cap 200 can be inserted into the first cylinder 100, increasing the contact area between the first cylinder 100 and the end cap 200, thereby improving the connection strength and sealing performance between the first cylinder 100 and the end cap 200.
[0043] To further improve the connection strength between the first cylinder 100 and the end cap 200, the inner wall of the first cylinder 100 is provided with an internal thread (not shown in the figure), and the inner wall of the snap-fit groove 230 is provided with an external thread (not shown in the figure). The first cylinder 100 and the end cap 200 are connected by the internal thread and the external thread.
[0044] To further improve the sealing performance of the first cylinder 100 and the end cap 200, the inner wall of the first cylinder 100 with one end opening towards the end cap 200 is provided with a first annular groove 120, and the inner wall of the snap-fit groove 230 is provided with a second annular groove 231. The second annular groove 231 and the first annular groove 120 are opposite each other in the radial direction of the first cylinder 100. The bubble reinforcement structure also includes a sealing ring (not shown in the figure). The sealing ring is located in the first annular groove 120 and the second annular groove 231 and abuts against the end cap 200 and the first cylinder 100, sealing the connection between the inner wall of the snap-fit groove 230 on the end cap 200 and the inner wall of the first cylinder 100.
[0045] Optionally, the second cylinder 300 is interference-fitted with the first cylinder 100 to increase the sealing performance of the entire bubble-reinforced structure.
[0046] Optionally, the radial dimension of the gap 401 along the second through hole 220 is 0.05 mm, that is, the second through hole 220 is expanded by 5 mils on one side from the shaft body 410 during machining, so as to facilitate the release of carbon dioxide in the bubble water.
[0047] Optionally, such as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the outer wall of the shaft body 410 is clearance-fitted with the inner wall of the second cylinder 300, which facilitates the sliding of the shaft body 410 within the second cylinder 300.
[0048] Furthermore, the second cylinder 300 has an annular boss 320 at one end facing the end cap 200. The outer diameter of the annular boss 320 is smaller than the outer diameter of the second cylinder 300, and the inner diameter of the annular boss 320 is smaller than the inner diameter of the second cylinder 300. The shaft body 410 passes through the inner ring of the annular boss 320 and the second cylinder 300 in sequence. The end of the annular boss 320 facing the end cap 200 abuts against the reinforcing block 420, increasing the gap between the second cylinder 300 and the shaft body 410, which facilitates the flow of bubble water into the second cylinder 300; and the distance between the end cap 200 and the second cylinder 300, which facilitates the entry of bubble water into the second cylinder 300.
[0049] Furthermore, the outer side of the annular boss 320 is provided with a slot 321. The slot 321 extends along the axial direction of the second cylinder 300 to the inner side wall of the second cylinder 300. The slot 321 can not only allow the bubble water coming out of the gap 401 to enter the second cylinder 300, but also serve as a flow channel for the bubble water in the second cylinder 300, facilitating the flow of the bubble water in the second cylinder 300.
[0050] In this embodiment, there are multiple slots 321. For example, the number of slots 321 can be two, three, or six. The multiple slots 321 are evenly spaced along the inner circumference of the second cylinder 300 (outer circumference of the annular boss 320). It should be noted that the end of the shaft body 410 away from the reinforcing block 420 does not extend beyond the second cylinder 300, that is, the end of the shaft body 410 away from the reinforcing block 420 is completely located inside the second cylinder 300 and is spaced apart from the second outlet 310.
[0051] This embodiment also provides a sparkling water device that can enhance the bubbles in the extruded sparkling water to improve its taste.
[0052] Specifically, the sparkling water device includes a container and the aforementioned bubble enhancement structure. The container is used to hold sparkling water, and the bubble enhancement structure can be installed at the outlet of the container. The outlet is connected to the first through hole 210. The bubbly water expelled from the outlet of the container enters the second through-hole 220 through the first through-hole 210, then impacts the reinforcing block 420 and flows through the gap 401 between the side wall of the reinforcing block 420 and the inner wall of the second through-hole 220. The bubbly water generates bubbles by stimulating the dissolved carbon dioxide through the combined action of the impact and the gap 401. The bubbly water with bubbles enters the second cylinder 300 and flows from the second outlet 310 of the second cylinder 300 to the first outlet 110 of the first cylinder 100. Since the radial dimension of the first outlet 110 is smaller than that of the second outlet 310, the bubbly water will generate a reverse force due to the smaller outlet size, pushing the reinforcing shaft 400 toward the end cap 200. This reduces the axial dimension of the reinforcing shaft 400 and the end cap 200 along the first cylinder 100, thereby reducing the flow velocity of the bubbly water in the second through-hole 220. This prevents the bubbly water from flowing too fast and having too great an impact force, which could lead to the overflow of carbon dioxide, thus reducing or even eliminating the bubbles.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
