Description

Technical Field

[0001] This application relates to the technical field of sparkling water, and particularly to a sparkling water generating device. Background Art

[0002] In the prior art, sparkling water is usually prepared by using an air pump to inflate an air dissolving tank, so that gas is mixed with the liquid in the air dissolving tank to form sparkling water. However, as the sparkling water is continuously output, the gas in the air dissolving tank is continuously consumed, while the liquid is continuously increasing, resulting in an imbalance of the gas-liquid ratio and a reduction in the generation efficiency of sparkling water.

[0003] To ensure the stable generation of sparkling water, the traditional solution usually adopts intermittent air replenishment, that is, when the air pressure is detected to be insufficient, the water path is closed, and then the air pump is used to supplement gas into the air dissolving tank. However, this air replenishment method has a significant problem: during the air replenishment period, since the water path is cut off, the user end cannot obtain a continuous supply of sparkling water, resulting in a serious impact on the water use experience. Summary of the Invention

[0004] This application provides a sparkling water generating device to solve the technical problem that when the existing sparkling water device replenishes air, the user cannot normally use the sparkling water.

[0005] This application provides a sparkling water generating device, including: A first cavity and a second cavity, the first cavity is connected with a water inlet end, and the second cavity is connected with a water outlet end; A first water flow path and a second water flow path are provided between the first cavity and the second cavity, wherein: A stop valve is provided in the first water flow path for controllably cutting off the water flow in this path; The second water flow path is a normally open path, and its flow cross-sectional area is smaller than that of the first water flow path; An air inlet is provided on the side wall of the second cavity, and its air inlet direction faces the water outlet end.

[0006] In a possible implementation manner, it further includes a partition plate. A first through hole is provided on the side wall of the first cavity, and a second through hole is provided on the partition plate. The first through hole and the second through hole are communicated to form the first water flow path. Among them, the diameter of the second through hole is smaller than that of the first through hole.

[0007] In a possible implementation manner, the second water flow path is provided on the partition plate, and the diameter of the second water flow path is smaller than that of the second through hole.

[0008] In a possible implementation manner, a plurality of limiting blocks are respectively provided on two opposite side walls of the second cavity, and two ends of the U-shaped baffle are respectively embedded in the area formed by the limiting blocks.

[0009] In a possible implementation, it further includes a cover plate, and the cover plate is detachably covered on the openings of the first cavity and the second cavity through a plurality of fasteners.

[0010] In a possible implementation, a rubber gasket is provided at one end of the opening facing the cover plate.

[0011] The above technical solution provided by the embodiments of the present application has the following advantages compared with the prior art: When the air volume in the second cavity is insufficient and air needs to be supplemented, the stop valve is closed to cut off the water flow in the first water flow path. Since the second water flow path is always open, after the water flow in the first water flow path is cut off, there is still water flow discharged at the water outlet end. At the same time, when the external device inflates the second cavity, as air is continuously filled into the second cavity, the air pressure in the second cavity gradually increases, and the bubble water remaining in the second cavity is pushed towards the water outlet end under the action of the gas pressure, forming an exhaust water flow. The water flow in the second water flow path, together with the exhaust water flow generated by the gas pressure, jointly ensures that there is still water flow discharged at the water outlet end during the inflation stage, meeting the normal water use requirements of users.

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0020] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0021] For ease of description, spatially relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the bubble water generating device in use or operation in addition to the orientation depicted in the figure. For example, if the position of the bubble water generating device in the figure is flipped or the posture changes or the motion state changes, then these directional indications will also change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will then be oriented as "above other elements or features" or "on other elements or features". Therefore, the example term "below" can include the orientations of above and below. The bubble water generating device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0022] To solve the technical problem that in the prior art, when a bubble water device is refilling air, users cannot use the bubble water normally, the present application provides a bubble water generating device, which can ensure that water still flows out of the water outlet end 104 when the stop valve 6 is in the closed state, so as to ensure that users can still use water normally when the device is refilling air.

[0023] Figures 1 to 3 A bubble water generating device provided by an embodiment of the present application includes: A first cavity 101 and a second cavity 102, the first cavity 101 is connected with a water inlet end 103, and the second cavity 102 is connected with a water outlet end 104; A first water flow path 3 and a second water flow path 4 are provided between the first cavity 101 and the second cavity 102. It can be understood that both the first water flow path 3 and the second water flow path 4 can connect the first cavity 101 and the second cavity 102, that is, both the first water flow path 3 and the second water flow path 4 can introduce the water in the first cavity 101 into the second cavity 102, where: A stop valve 6 is provided in the first water flow path 3 for controllably truncating the water flow in this path; The second water flow path 4 is a normally open path, and its flow cross-sectional area is smaller than that of the first water flow path 3; An air inlet 105 is provided on the side wall of the second cavity 102 for refilling air into the second cavity 102, and the air inlet direction of the air inlet 105 faces the water outlet end 104.

[0024] In the above technical solution, during the air refilling process of the device, the stop valve 6 closes the first water flow path 3 (the closing degree can be adjusted according to the actual situation) to control the water flow state and ensure the smooth progress of the air refilling operation. After the air refilling is completed, the stop valve 6 is opened, and the device resumes the normal operation state. Specifically, when the air volume in the second cavity 102 is insufficient and affects the generation of bubble water, the stop valve 6 is closed. At this time, the external air filling device is started, and air is filled into the second cavity 102 through the air inlet 105. As the air is continuously filled into the second cavity 102, the air pressure in the second cavity 102 gradually increases, and the remaining bubble water is pushed towards the water outlet end 104 under the action of the gas pressure, forming an exhaust water flow. At the same time, since the second water flow path 4 is in the normally open state, there will always be water flowing out of the second water flow path 4. The water flow in the second water flow path 4 plus the exhaust water flow generated by the gas pressure together ensure that water still flows out of the water outlet end 104 during the air filling stage, meeting the normal water use requirements of users.

[0025] Please refer to Figure 1, in a possible implementation, it further includes a partition plate 2. The side wall of the first cavity 101 is provided with a first through hole 1011, and the partition plate 2 is provided with a second through hole 201. The first through hole 1011 communicates with the second through hole 201 to form a first water flow path 3. Among them, the diameter of the second through hole 201 is smaller than that of the first through hole 1011. During use, water flows into the second through hole 201 from the first through hole 1011. Since the diameter of the second through hole 201 is smaller than that of the first through hole 1011, when water flows from the first through hole 1011 into the second through hole 201, the flow area decreases. According to the principle of fluid mechanics, the water flow velocity will increase, and the pressure will also increase accordingly. The high-speed water flow is injected into the air in the second cavity 102 with a relatively large pressure. This high-speed and high-pressure water flow can quickly contact and mix with the air, causing the air to be dispersed in the water in the form of tiny bubbles, initially forming bubble water.

[0026] Specifically, the second water flow path 4 is provided on the partition plate 2, and the diameter of the second water flow path 4 is smaller than that of the second through hole 201. The second water flow path 4 is formed as a through hole structure. After water enters the first cavity 101 from the water inlet end 103, there are two paths to enter the second cavity 102. The first path is through the first water flow path 3, which is formed by the communication of the first through hole 1011 and the second through hole 201. Water flows from the first through hole 1011 to the second through hole 201, and then flows into the second cavity 102 from the second through hole 201. The second path is through the second water flow path 4, and the diameter of the second water flow path 4 is smaller than that of the second through hole 201.

[0027] That is to say, when the diameter of the second water flow path 4 is smaller than that of the second through hole 201, and the diameter of the second through hole 201 is smaller than that of the first through hole 1011, water mainly flows into the second cavity 102 from the first water flow path 3, that is, from the first through hole 1011 to the second through hole 201 and then into the second cavity 102. It can be understood that even during air supplementation, the amount of water flowing from the second water flow path 4 into the second cavity 102 will not cause gas-liquid imbalance, ensuring the smooth progress of air supplementation and the stable generation of bubble water.

[0028] Please refer to Figure 2 and Figure 3 , in a possible implementation, it further includes a U-shaped baffle 5. The concave direction of the U-shaped baffle 5 is opposite to the water outlet directions of the first water flow path 3 and the second water flow path 4.

[0029] It can be understood that the water flowing out of the second through hole 201 shoots into the second cavity 102 at a high speed and mixes with the air above the U-shaped baffle 5, forming a water flow with a certain bubble content. The special structure of the U-shaped baffle can play a certain buffering and guiding role on the water flow, making the water flow stay inside the U-shaped baffle 5 for a period of time, further promoting the fusion of bubbles and water, achieving primary air dissolution, and forming micro-nano bubble water. As water continuously enters the U-shaped baffle 5, when the U-shaped baffle 5 is filled with water, the excess water will overflow from the edge of the U-shaped baffle 5. The overflowing water flows down in a waterfall shape to the second cavity 102, and during this process, the water flow comes into contact and mixes with the air in the second cavity 102 again.

[0030] Due to the large surface area and certain impact force of the waterfall-shaped water flow, it can further dissolve gases such as oxygen in the air into the water, making the bubbles smaller and more uniform, and achieving secondary air dissolution. After two air dissolution processes, the finally generated micro-nano bubble water has a higher quality.

[0031] In particular, in a possible implementation manner, the concave surface of the U-shaped baffle 5 is provided with a through hole 501 penetrating along its axial direction, and the water inlet end 103, the second water flow passage 4, the through hole 501, and the water outlet end 104 are coaxially opposite. That is to say, on the second water flow passage 4, when water enters the first cavity 101 from the water inlet end 103, a small part of the water directly flows into the water outlet end 104 along the paths of the second water flow passage 4 and the through hole 501. At the same time, when air is supplemented, the gas pressure forces the remaining bubble water flow in the second cavity 102 to flow towards the water outlet end 104, and these two water flows flow towards the water outlet end 104 together, ensuring that the user can continue to use water during the air supplementation stage.

[0032] It should be noted that the stop valve 6 of the present application is a normally open stop valve. When gas needs to be supplemented to the second cavity 102, the stop valve 6 needs to be closed. At this time, the water flow in the first water flow passage 3 will be cut off.

[0033] Please refer to again Figure 2 , in a possible implementation manner, several limiting blocks 1021 are respectively provided on the two opposite side walls of the second cavity 102, and the two ends of the U-shaped baffle 5 are respectively embedded in the areas formed by the limiting blocks 1021. The limiting blocks 1021 provide accurate positioning points for the U-shaped baffle. The two ends of the U-shaped baffle 5 are respectively embedded in the areas formed by the limiting blocks 1021, ensuring that the position of the U-shaped baffle 5 is accurate after installation and will not be displaced due to water flow impact or external vibration, ensuring the continuity and stability of the air dissolution process.

[0034] In a possible implementation, it further includes a cover plate 7, which is detachably covered on the openings 106 of the first cavity 101 and the second cavity 102 through a plurality of fasteners. It can be understood that when the bubble water device is in a non-working state, the user can clean the first cavity 101 and the second cavity 102 through the opening 106 or conduct internal inspection and maintenance on these two cavities, which improves the service life of the bubble water device and at the same time ensures the cleanliness of the water used by the user. In the working state, the cover plate 7 tightly seals the opening 106, making the first cavity 101 and the second cavity 102 independent, ensuring the stability and efficiency of the air dissolution process. That is to say, the cover plate 7 can prevent the water flow from communicating with each other through the opening 106, thereby preventing the aggregation and rupture of bubbles and improving the air dissolution effect.

[0035] In a possible implementation, a rubber gasket 8 is provided at one end of the opening 106 facing the cover plate 7. The rubber gasket 8 is located between the opening 106 and the cover plate 7. When the cover plate 7 is fixed to the opening 106 through fasteners, the rubber gasket 8 is compressed to form a tight seal, which helps to prevent water leakage from the opening 106 and ensures the sealing performance of the bubble water device in the working state.
