Description

Technical Field

[0001] The present invention relates to the technical field of carbonated spring preparation, and in particular to a carbonated spring preparation device. Background Art

[0002] The main component of carbonated spring is free carbon dioxide. When its content is above 1 gram / liter, it is called carbonated spring, commonly known as "natural soda". Carbonated spring can give special stimulation to the skin sensory nerves, because carbonic acid can be spread all over the surface of human skin in the form of small bubbles and form a layer of carbonic acid gas film, so you will feel warm, happy and relaxed immediately after bathing. The bubble film can stimulate the skin's peripheral receptors, and then enter the human body through the skin, stimulating blood vessels to cause capillary dilation and cause skin flushing. Improve skin blood circulation and enhance resistance. The pH value of carbonated spring is about 4.5-5.5, which is weakly acidic and has bactericidal function. The pH value is similar to that of human skin and hair, and is more friendly than ordinary water.

[0003] Existing carbonated spring preparation devices usually adopt a small-hole jet mode, in which the collision and mixing of gas and liquid are not sufficient, and the carbonated spring produced has a low concentration and poor effect, resulting in the need to consume more gas and liquid, causing waste of gas and liquid.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] It should be understood that, in the description of the present application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0028] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] like Figures 1 to 3 As shown, an embodiment of the present invention provides a carbonated spring preparation device, which includes a water inlet pipe 1, an air inlet pipe 2 and a mixing liquid pipe 4, the water inlet pipe 1 has a first outlet portion 11, the air inlet pipe 2 is connected to the water inlet pipe 1, and the two form a mixed flow chamber 3 at the connection point, the air inlet pipe 2 has a second outlet portion 21 protruding toward the mixing flow chamber 3, and the second outlet portion 21 extends into the first outlet portion 11, and the mixing liquid pipe 4 is connected to the mixing flow chamber 3.

[0030] Based on the above structure, compared with making the gas and liquid collide in the mixed flow chamber 3, the second outlet portion 21 extends into the first outlet portion 11 so that the gas and liquid directly collide more fully in the first outlet portion 11, thereby maximizing the collision energy. The gas then returns to the mixed flow chamber 3 with the liquid for further mixing, which enhances the mixing of gas and liquid and improves the solubility of gas relative to liquid. The prepared carbonated spring has a higher concentration and better effect. That is, the present carbonated spring preparation device achieves collision pressurization through a relatively simple structure, thereby increasing the concentration of carbonated spring, reducing the consumption of gas and liquid, and avoiding waste of gas and liquid.

[0031] Alternatively, considering that solubility is also related to pressure, the greater the pressure, the higher the solubility, e.g. Figure 3 As shown, in this embodiment, the intake pipe 2 has an end wall portion 22, the second outlet portion 21 is convexly arranged on the end wall portion 22, and the end wall portion 22 has a collision surface 221 arranged directly opposite to the first outlet portion 11. Based on this, when the gas mixture liquid flows out of the first outlet portion 11 after the counter-collision in advance in the first outlet portion 11, it instantly collides with the directly opposite collision surface 221 and changes the flow direction, so that the momentum of the gas mixture liquid is instantly reduced, thereby generating a region with a very large local pressure near the collision surface 221, further improving the solubility of the gas relative to the liquid, so that the concentration of the carbonated spring is further improved.

[0032] Alternatively, if Figure 3 As shown, in this embodiment, a gap 6 is formed between the outer peripheral wall of the second outlet 21 and the inner peripheral wall of the first outlet 11. Based on this, the gas and liquid collide and flow back through the gap 6, so that they are accelerated and collide with the collision surface 221, so that the gas and liquid are mixed more fully.

[0033] Alternatively, if Figure 2 As shown, in this embodiment, the carbonated spring preparation device further includes a deflection portion 5, which is arranged in the flow path direction from the mixing chamber 3 to the mixed liquid pipe 4, and has a plurality of flow holes 54. In this way, the gas mixture collides with the deflection portion 5 and changes the flow direction. Similarly, the momentum is instantly reduced, the pressure is increased, and the solubility of the gas relative to the liquid is increased. Subsequently, the gas mixture passes through the flow holes 54, thereby being accelerated, so that the collision and dissolution are further enhanced in the next collision.

[0034] Alternatively, if Figure 2As shown, in this embodiment, the deflector 5 includes a first deflector plate 51 and a second deflector plate 52 arranged in sequence along the flow path direction, and a plurality of flow holes 54 are evenly distributed on the first deflector plate 51 and the second deflector plate 52, and the flow holes 54 of the first deflector plate 51 and the flow holes 54 of the second deflector plate 52 are staggered in the flow path direction. In this way, the gas mixture is accelerated when passing through the flow holes 54 of the first deflector plate 51 after colliding with the first deflector plate 51. The staggered arrangement of the flow holes 54 of the first deflector plate 51 and the flow holes 54 of the second deflector plate 52 enables the gas mixture to collide with the plate body of the second deflector plate 52 after being accelerated, thereby further improving the solubility of the gas. Secondly, the flow holes 54 of the first deflector plate 51 and the flow holes 54 of the second deflector plate 52 are evenly distributed, which is easy to manufacture and has a more reasonable arrangement. The functions of collision and pressurization can be achieved without offsetting or centering the flow holes 54, while achieving sufficient collision of the gas mixture. Of course, the deflector 5 may also include a greater number of deflector plates.

[0035] Alternatively, if Figure 5 As shown, in this embodiment, the first deflector 51 has an annular protrusion 511 protruding toward the mixing chamber 3, the mixed liquid tube 4 has an inner boss, the protrusion 511 is clamped on the inner boss, and the flow hole 54 is arranged within the range of the protrusion 511. In this way, it is convenient to install and fix the first deflector 51, and when the gas mixed liquid flowing out of the mixing chamber 3 collides with the protrusion 511, the flow is reversed, so that the gas is further dissolved in the liquid, and the bubbles are fined, which is conducive to improving the user's comfort.

[0036] Alternatively, if Figure 2 and Figure 4 As shown, in this embodiment, the deflection part 5 also includes a deflection wall 53 arranged on the upstream side of the first deflector plate 51, and the deflection wall 53 is formed by opening a plurality of flow holes 54 in the wall of the mixed flow chamber 3, and the mixed flow chamber 3 is connected to the mixed liquid pipe 4 through the flow holes 54. Based on this, the gas mixture collides with the deflection wall 53 to complete the initial pressurization, and then the first deflector plate 51 and the second deflector plate 52 are used to achieve secondary and tertiary pressurization, thereby greatly improving the solubility of the gas relative to the liquid and preparing a carbonated spring with a higher concentration. In addition, the method of opening the flow holes 54 in the cavity wall to form the deflection wall 53 reduces the number of deflection plates, so that the carbonated spring preparation device has a higher degree of integration and a more simple and compact structure.

[0037] Alternatively, if Figure 4As shown, in this embodiment, the mixing chamber 3 is cylindrical, and a plurality of flow holes 54 are evenly distributed on the deflection wall 53 along the circumference of the mixing chamber 3. In this way, part of the chamber wall of the mixing chamber 3, that is, the deflection wall 53, is arc-shaped, so that the flow holes 54 distributed thereon extend in multiple different directions, so that the gas mixture flows in multiple directions when passing through the deflection wall 53, thereby colliding with each other and with the wall surface of the mixing liquid pipe 4 and the wall surface of the first deflection plate 51, that is, the collision of the gas mixture is more complete, and multiple areas with relatively large local pressures are generated, further improving the solubility of the gas relative to the liquid.

[0038] Alternatively, if Figure 2 As shown, in this embodiment, the diameters of the flow holes 54 of the deflector wall 53, the flow holes 54 of the first deflector plate 51, and the flow holes 54 of the second deflector plate 52 are successively reduced and the number is successively increased, so that the flow areas of the deflector wall 53, the first deflector plate 51, and the second deflector plate 52 are similar or equal. Based on this, the diameter of the flow holes 54 is successively reduced, which is conducive to accelerating the gas mixture before each collision pressurization, thereby maximizing the collision energy, and the flow holes 54 with successively reduced diameters are easier to be arranged staggered with each other, so that the collision surface 221 of the first deflector plate 51 and the second deflector plate 52 is increased. In addition, the number of the flow holes 54 is successively increased, so that the flow areas of the deflector wall 53, the first deflector plate 51, and the second deflector plate 52 can be maintained similar or equal, so that the flow rate of the gas mixture will not decrease when the gas mixture is pressurized, but will flow at a substantially the same flow rate.

[0039] Alternatively, if Figure 2 As shown, in this embodiment, the mixed liquid pipe 4 has a tapered surface 42, and the tapered surface 42 is located on the downstream side of the second deflector 52. The gas mixed liquid accelerated by the second deflector 52 collides with the tapered surface 42, generating a tiny vortex, thereby making the bubbles in the gas mixed liquid more miniaturized.

[0040] Alternatively, if Figure 2 As shown, in this embodiment, at least part of the mixed liquid pipe 4 is bent so that the central axis of the bent pipe section is parallel to the central axis of the water inlet pipe 1. Based on this, the liquid outlet of the mixed liquid pipe 4 and the liquid inlet of the water inlet pipe 1 can be arranged on the same side, which is conducive to the connection and arrangement of the carbonated spring preparation device and the pipeline. The connection of the pipeline on the same side is conducive to saving space and the arrangement is more reasonable.

[0041] Specifically, Figure 2As shown, the mixed liquid pipe 4 includes a first pipe section 43, a second pipe section 44 and a third pipe section 45, a first deflector 51 and a second deflector 52 are arranged in the first pipe section 43, the second pipe section 44 is detachably connected to the first pipe section 43, and a first sealing ring 7 is arranged between the second pipe section 44 and the first pipe section 43, a conical surface 42 is arranged in the second pipe section 44, and the third pipe section 45 is bent to form a predetermined angle with the second pipe section 44. Based on this, the second pipe section 44 can be detached from the first pipe section 43 to facilitate the inspection and cleaning of the first deflector 51 and the second deflector 52.

[0042] Alternatively, if Figure 1 and Figure 2 As shown, in this embodiment, a temperature sensor 41 is provided in the mixed liquid pipe 4, and the temperature sensor 41 is provided on the downstream side of the conical surface 42. The temperature sensor 41 can detect the temperature of the gas mixed liquid, and transmit it to the terminal device to adjust the outlet liquid temperature.

[0043] Alternatively, if Figure 2 As shown, in this embodiment, a filter 23 is provided in the air inlet pipe 2, and the filter 23 is provided on the upstream side of the second outlet portion 21. Preferably, the filter 23 is composed of a copper sintered filter element. Based on this, the gas can be filtered to remove impurities, so that the carbonated spring reaching the user end has fewer impurities.

[0044] Optionally, in this embodiment, a gas flow detection module is further provided in the air intake pipe 2, and the gas flow detection module is provided on the upstream side of the filter 23. In this way, the gas flow can be monitored to control the intake volume and the proportion of water vapor.

[0045] Alternatively, if Figure 2 and Figure 3 As shown, in this embodiment, the air inlet pipe 2 has a large diameter portion 24 and a small diameter portion 25, which are arranged in sequence along the flow direction of the gas, and the small diameter portion 25 is formed in the second outlet portion 21. Based on this, the gas is pressurized and accelerated when flowing through the large diameter portion 24 and the small diameter portion 25, so that the collision between the gas and the liquid is more violent and the mixing is more complete. Preferably, the first outlet portion 11 is formed with a narrow portion 111, so that the liquid is accelerated when flowing through the narrow portion 111.

[0046] Alternatively, if Figure 3 As shown, in this embodiment, the second outlet portion 21 has a plurality of gas outlet holes 211, which are disposed at the end of the second outlet portion 21 and communicated with the small diameter portion 25. In this way, the gas is accelerated by secondary pressurization when flowing through the gas outlet holes 211, further enhancing the collision and mixing of the gas and the liquid.

[0047] Alternatively, if Figure 2As shown, in this embodiment, the air inlet pipe 2 includes a fourth pipe section 27 and a fifth pipe section 28, the fourth pipe section 27 and the fifth pipe section 28 are detachably connected, the fifth pipe section 28 is connected to the water inlet pipe 1, the fifth pipe section 28 has an end wall and a first outlet portion 11, and the large diameter portion 24 and the small diameter portion 25 are both located in the fifth pipe section 28. The fourth pipe section 27 has an annular surrounding wall 271, the surrounding wall 271 and the fourth pipe section 27 form an annular mounting groove 272, and the end of the fifth pipe section 28 is inserted into the mounting groove 272. Based on this, the fourth pipe section 27 and the fifth pipe section 28 can be disengaged to check and clean the impurities in the large diameter portion 24. The surrounding wall 271 plays a role in preventing gas leakage. A second sealing ring 8 is provided between the fourth pipe section 27 and the fifth pipe section 28, and the second sealing ring 8 further plays a role in preventing gas leakage.

[0048] Alternatively, if Figure 2 As shown, in this embodiment, a flow meter 12 is provided in the water inlet pipe 1, and the flow meter 12 is provided on the upstream side of the first outlet 11. In this way, the flow rate of the incoming water can be monitored to control the amount of incoming water and the ratio of water and gas.

[0049] The preparation principle of the carbonated spring preparation device provided in the embodiment of the present invention is as follows: after the gas enters from the air inlet pipe 2, it is filtered by the filter 23, and is initially accelerated by the large diameter portion 24 and the small diameter portion 25, and then flows through the air outlet 211 to be accelerated for the second time, and fully collides with the liquid in the first outlet portion 11. The gas mixture is accelerated when it flows back through the gap between the first outlet portion 11 and the second outlet portion 21, and then collides with the collision surface 221 of the end wall, and the instantaneous momentum is suddenly reduced, thereby generating an area with very large local pressure, thereby increasing the solubility of the gas relative to the liquid, thereby increasing The concentration of the gas mixture, that is, the carbonated spring, is increased; after being fully mixed in the mixed flow chamber 3, the gas mixture collides with the deflection wall 53 and completes the initial pressurization, then flows out from the flow hole 54 of the deflection wall 53, and is sprayed in multiple directions and collides with the mixed liquid pipe 4 and the wall of the first deflector 51 to complete the secondary pressurization, then flows out from the flow hole 54 of the first deflector 51 and collides with the wall of the second deflector 52 to complete the tertiary pressurization, thereby further increasing the concentration of the gas mixture; the gas mixture flows through the conical surface 42, generating tiny vortices, which refine the bubbles.

[0050] In summary, the embodiment of the present invention provides a carbonated spring preparation device, which is mainly composed of a water inlet pipe 1, an air inlet pipe 2 and a mixed liquid pipe 4, the water inlet pipe 1 has a first outlet 11, the air inlet pipe 2 is connected to the water inlet pipe 1, and the two form a mixed flow chamber 3 at the connection point, the air inlet pipe 2 has a second outlet 21 protruding toward the mixed flow chamber 3, and the second outlet 21 extends into the first outlet 11, and the mixed liquid pipe 4 is connected to the mixed flow chamber 3. Compared with the prior art, the carbonated spring preparation device has the advantages of sufficient collision mixing, high carbonated spring concentration, and saving gas and liquid.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
