Technical Field

[0001] The utility model relates to the technical field of a sparkling water production device, in particular to a soda bladder for sparkling water. Background Art

[0002] Chinese Patent No. CN202220064635.8 disclosed on September 2, 2022 a bubble water preparation device with a water tank, comprising a water tank having a first cavity therein, the water tank being provided with a first water outlet connected to the first cavity; a cold tank having a second cavity therein, the cold tank being provided with a water inlet and a second water outlet connected to the second cavity, a water inlet pipeline being provided between the water inlet and the first water outlet, a first water pump being provided on the water inlet pipeline, the second water outlet being connected to a water outlet pipeline, and a water outlet valve being provided on the water outlet pipeline; a refrigeration device for cooling the water contained in the second cavity; a safety pipeline being connected to the top of the cold tank, a first safety valve being provided on the safety pipeline, an air inlet being also provided at the bottom of the cold tank, and a gas cylinder being provided with an air outlet, an air inlet pipeline being provided between the air outlet and the air inlet. The discharge of the bubble water in this structure requires the help of a water pump, and the air inlet is set at the bottom, so the water can easily flow back to the air supply pipe. At the same time, because the carbon dioxide directly enters the water, the pressure of the carbon dioxide is relatively high and the flow rate is relatively fast. If it fails to merge with the water, it is easily released from the water instantly, resulting in a low gas content in the bubble water. In addition, the refrigeration device of this structure is set outside the cold tank, and the refrigeration effect is relatively weak. Utility Model Content

[0003] The utility model aims to provide a soda bladder with simple and reasonable structure, convenient water intake and high efficiency in preparing bubble water.

[0004] The purpose of the utility model is achieved in this way:

[0005] A soda bladder comprises a pressure tank body, wherein an inner cavity is arranged in the pressure tank body, an air inlet nozzle, a water inlet nozzle and a water outlet pipe are arranged at the upper part of the pressure tank body, the air inlet nozzle and the water inlet nozzle are communicated with the upper part of the inner cavity of the pressure tank body, and the lower end of the water outlet pipe extends to the lower part of the inner cavity.

[0006] The purpose of the utility model can also be solved by the following technical measures:

[0007] As a more specific solution, the upper ends of the air inlet nozzle, the water inlet nozzle and the water outlet pipe are all located on the top of the pressure tank body.

[0008] As a further solution, the inner cavity of the pressure tank is further provided with an atomizing head, and the atomizing head is connected to the inner end of the water inlet nozzle.

[0009] As a further solution, the water inlet is located at the top center of the pressure tank.

[0010] As a further solution, the inner cavity of the pressure tank body is also provided with an evaporator tube, which includes a refrigerant inner tube and a food-grade material outer tube. The food-grade material outer tube is sleeved outside the refrigerant inner tube, and the ends of the refrigerant inner tube and the food-grade material outer tube both extend out of the top of the pressure tank body. The pressure tank body is provided with an opening corresponding to the food-grade material outer tube, and the food-grade material outer tube is sealed and connected to the opening. The end of the refrigerant inner tube extends out of the end of the food-grade material outer tube, and the port of the food-grade material outer tube is gap-matched with the outer wall of the refrigerant inner tube. The gap between the inside of the food-grade material outer tube and the refrigerant inner tube is connected to the outside through the port of the food-grade material outer tube.

[0011] As a further solution, a drainage nozzle is provided at the bottom of the pressure tank.

[0012] As a further solution, the pressure tank body is also provided with a probe tube, which is a blind tube, the blind end of which extends to the lower part of the inner cavity of the pressure tank body and the open end extends to the outside of the top of the pressure tank body. The interior of the blind tube is used to insert a temperature sensor.

[0013] As a further solution, a threaded pipe is further provided on the top of the pressure tank body, the threaded pipe is communicated with the inner cavity of the pressure tank body, and the threaded pipe is used to install a water level detection probe.

[0014] As a further solution, a ground connection electrode is provided on the top of the pressure tank.

[0015] As a further solution, the outer wall of the pressure tank is also wrapped with a thermal insulation layer.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) This soda tank is a pressure tank with good sealing performance. At the same time, it adopts upper air and water intake. When carbon dioxide and water enter the tank, they begin to mix in the upper part of the inner cavity, and a certain air pressure is formed in the upper part of the inner cavity. When the water level is higher than the lower end of the water outlet pipe, the water outlet pipe is opened, and the water in the tank enters the water outlet pipe under pressure and is discharged without the need for additional power to pump out.

[0018] (2) The inner end of the water inlet of this soda tank is also equipped with an atomizer head to break up the water into mist, which allows for more complete contact with the carbon dioxide. In addition, there is a certain pressure inside the tank, which helps the carbon dioxide to blend into the water, making the carbon dioxide saturation of the sparkling water higher and the taste better.

[0019] (3) This soda tank has an evaporator installed inside to directly cool the sparkling water, which reduces energy loss and keeps the temperature lower, making the carbon dioxide more stable in the water and less likely to be released.

[0020] (4) The evaporator tube of this soda tank has a double-layer structure. The outer layer is made of food-grade material, which meets the requirements of drinking water. At the same time, it strengthens the protection of the refrigerant inner tube and reduces the chance of damage to the refrigerant inner tube. In addition, the gap between the inner and outer tubes is connected to the outside through the outer tube port. Once the refrigerant inner tube ruptures, the refrigerant medium will only be discharged into the atmosphere, avoiding entering the water body, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0032] Example 1, see Figures 1 to 6 As shown, a soda bladder comprises a pressure tank body 1, wherein an inner cavity 11 is provided in the pressure tank body 1, an air inlet nozzle 13, a water inlet nozzle 12 and a water outlet pipe 2 are provided at the upper portion of the pressure tank body 1, the air inlet nozzle 13 and the water inlet nozzle 12 are communicated with the upper portion of the inner cavity 11 of the pressure tank body 1, and the lower end of the water outlet pipe 2 extends to the lower portion of the inner cavity 11.

[0033] The upper ends of the air inlet nozzle 13 , the water inlet nozzle 12 and the water outlet pipe 2 are all located at the top of the pressure tank body 1 .

[0034] The inner cavity 11 of the pressure tank body 1 is also provided with an atomizing head, and the atomizing head is connected to the inner end of the water inlet nozzle 12 .

[0035] The water inlet 12 is located at the top center of the pressure tank body 1 .

[0036] The upper and lower ends of the water outlet pipe 2 are a water outlet end 21 and a water inlet end 22 respectively, and both the water outlet end 21 and the water inlet end 22 are bent and inclined.

[0037] The outer periphery of the air inlet nozzle 13 and the outer end of the water outlet pipe 2 is provided with an annular groove B. When connected with the silicone tube, the annular groove B plays an anti-slip role, and can better cooperate with the pipe clamp to achieve an anti-slip effect. In addition, the annular groove B can also be conveniently fastened and fixed with the quick connector (the internal buckle of the quick connector can clamp the annular groove B).

[0038] The inner cavity 11 of the pressure tank body 1 is also provided with an evaporation tube 3, which includes a refrigerant inner tube 31 and a food-grade material outer tube 32. The food-grade material outer tube 32 is sleeved outside the refrigerant inner tube 31, and the ends of the refrigerant inner tube 31 and the food-grade material outer tube 32 both extend out of the top of the pressure tank body 1. The pressure tank body 1 is provided with an opening corresponding to the food-grade material outer tube 32, and the food-grade material outer tube 32 is sealed and connected to the opening. The end of the refrigerant inner tube 31 extends out of the end of the food-grade material outer tube 32, and the port of the food-grade material outer tube 32 is matched with the outer wall gap of the refrigerant inner tube 31. The gap between the inside of the food-grade material outer tube 32 and the refrigerant inner tube 31 is connected to the outside through the port of the food-grade material outer tube 32.

[0039] The evaporation tube 3 is spirally wound, and the material of the food-grade outer tube 32 is food-grade stainless steel.

[0040] One end of the refrigerant inner tube 31 has a narrow opening 33, which is convenient for connection with a capillary tube in a refrigeration circuit, but is not shown in the figure.

[0041] A drainage nozzle 15 is provided at the bottom of the pressure tank body 1 .

[0042] The pressure tank body 1 is also provided with a probe tube 4 which is a blind tube, the blind end of which extends to the lower part of the inner cavity 11 of the pressure tank body 1 and the open end extends to the outside of the top of the pressure tank body 1 . The interior of the blind tube is used to insert a temperature sensor.

[0043] The top of the pressure tank body 1 is also provided with a threaded tube 14, which is communicated with the inner cavity 11 of the pressure tank body 1 and is used to install a water level detection probe. In this embodiment, the threaded tube 14 is an external threaded tube.

[0044] A ground connection electrode 5 is provided on the top of the pressure tank body 1 .

[0045] The outer wall of the pressure tank 1 is also wrapped with an insulation layer, and the insulation layer, atomizer head, temperature sensor and water level detection probe are not shown in the figure. The insulation layer includes foam material and insulation cotton. The foam thickness of the bottom of the pressure tank 1 is 10mm, the foam thickness of the tank body is 15mm, and the top is made of flame-retardant insulation cotton with a thickness of 15mm. The surface of the insulation layer is covered with PVC film.

[0046] Its working principle is: carbon dioxide enters the upper part of the inner cavity 11 of the pressure tank body 1 through the air inlet nozzle 13, and drinking water enters the upper part of the inner cavity 11 through the water inlet nozzle 12. Carbon dioxide begins to mix with drinking water (if an atomizer head is provided at the inner end of the water inlet nozzle 12, the mixing is better), thereby preparing bubble water. When the bubble water reaches a certain water level, the preparation is stopped. Since the pressure tank body 1 is closed, an air chamber with a certain pressure is formed in the upper part of the inner cavity 11. When the water outlet pipe 2 is connected to the outside world (opened), water enters the water outlet pipe 2 under pressure and is discharged; when the water level is lower than a certain range, carbon dioxide and drinking water continue to be supplemented, which realizes the supplementary preparation of bubble water on the one hand and the pressure in the tank on the other hand.

[0047] The evaporation tube 3 directly cools the bubble water in the inner cavity 11, which reduces energy loss and can achieve a lower temperature, making carbon dioxide more stable in the water and less likely to be released. Moreover, the evaporation tube has a double-layer structure, and the outer layer is made of food-grade material, which meets the requirements of drinking water. At the same time, it strengthens the protection of the refrigerant inner tube, reducing the chance of damage to the refrigerant inner tube; and the gap between the inner and outer tubes is connected to the outside through the outer tube port. Once the refrigerant inner tube is broken, the refrigerant medium will only be discharged into the atmosphere, avoiding entering the water body, which is safer.

[0048] The difference between the second embodiment and the first embodiment is: Figures 7 to 10 As shown, the top and bottom of the pressure tank body 1 are both arc-shaped, and have a stronger pressure bearing capacity. Its pressure bearing (durability) requirement is to withstand a pressure of 1.0 MPa for 5 minutes without leakage and permanent deformation.

[0049] The air inlet nozzle 13 , the water inlet nozzle 12 and the water outlet pipe 2 are distributed in a straight line, and the air inlet nozzle 13 and the water outlet pipe 2 are located on the left and right sides of the water inlet nozzle 12 respectively.

[0050] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements fall within the scope of the utility model to be protected, and the scope of protection of the utility model is defined by the attached claims and their equivalents.
