Description

Technical Field

[0001] The utility model belongs to the technical field of beverage equipment and relates to an atomization structure of a carbonated water tank. Background Art

[0002] Carbonated water is a common beverage in today's life. It is generally made by pressing carbon dioxide into purified drinking water. Due to its unique taste, it is widely favored by consumers.

[0003] In the current existing technology, with the continuous improvement of living standards, food hygiene and safety is a part of life that is highly valued. Carbonated beverages sold on the market have been criticized by consumers due to the various additives and sugar ingredients contained therein. Therefore, small-scale carbonated water preparation machines have gradually entered the public eye. The carbonated water preparation machines in the existing technology generally include a tank body that is hollow inside and has a faucet on the outer wall. An air inlet pipe and a water inlet pipe are connected to the tank body. When working, carbon dioxide is input into the tank cavity through the air inlet pipe, and pure water is input into the tank cavity through the water inlet pipe, so that the two are fully mixed in the tank cavity to prepare carbonated water.

[0004] But in reality, the carbon dioxide introduced into the tank only makes the pressure inside the tank greater than the outside pressure. The pure water and carbon dioxide cannot be fully mixed. The actual amount of carbon dioxide injected into the pure water is very small. As a result, the taste of the prepared carbonated water does not meet the taste requirements of consumers. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose an atomization structure of a carbonated water tank. The technical problem to be solved by the utility model is: how to improve the carbonation effect of pure water in the tank body.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an atomization structure of a carbonated water tank, the carbonated water tank includes a tank body with a cavity inside, the atomization structure includes a one-way valve and a water spray joint vertically connected to the tank body, characterized in that the water spray joint has a flow channel one vertically arranged and penetrating the upper end of the water spray joint, the one-way valve is connected to the upper end of the water spray joint and communicated with the flow channel one, the lower end of the water spray joint extends into the cavity, and a water spray hole connected to the flow channel one is opened on the outer side wall of the lower end of the water spray joint, and the water spray hole is arranged toward the inner side wall of the cavity.

[0007] The working principle of the atomization structure of the carbonated water tank is as follows: carbon dioxide is introduced into the cavity of the tank body through an independent gas path, and purified water is input into the cavity of the tank body through a one-way valve and a water spray joint in turn. In this process, the one-way valve plays a role in one-way input to prevent backflow, and the flow channel is specifically opened into a slender shape along the length direction of the water spray joint. In addition, the existence of gravity can play a role in pressurizing and accelerating the purified water, ensuring that the flow rate of purified water when input into the cavity of the tank body is faster, and finally making the purified water sprayed out from the water spray hole opened on the outer side wall of the lower end of the water spray joint. At this time, the purified water impacts the inner wall of the cavity at a relatively high speed. Under the action of the impact force and gravity, The pure water is dispersed into fine particles due to the impact force. At the same time, the residual energy in the water droplets can ensure that the water droplets continuously collide with the inner wall of the cavity and with each other, thereby achieving the effect of further refining the granular water droplets, thereby ensuring that the pure water spreads in the cavity in the form of fine particles or even mist. The cavity is itself filled with carbon dioxide at this time, so these granular water droplets can fully contact with carbon dioxide during the process of impact and refinement, and finally continue to deposit at the bottom of the cavity under the action of gravity, thereby improving the carbonation effect of the pure water in the tank, thereby ensuring the drinking taste of consumers.

[0008] In the above-mentioned atomization structure of the carbonated water tank, the water spray holes are provided in a plurality and are arranged near the lower edge of the water spray joint, and the plurality of water spray holes are arranged at intervals along the circumferential direction of the outer wall of the lower end of the water spray joint. The arrangement position of the water spray holes can ensure that the flow distance of the pure water in the flow channel is the maximum, so as to ensure that the water flow velocity is at the maximum state under the support of the inner wall of the flow channel and gravity, and the number of water spray holes can ensure higher output efficiency, thereby ensuring the efficiency of carbonated water preparation.

[0009] In the above-mentioned atomization structure of the carbonated water tank, the one-way valve includes a spring, a valve core and a columnar valve body, a flow channel 2 is provided on the top of the valve body, the lower end of the valve body is detachably connected to the upper end of the water spray joint and forms a water-containing cavity connecting the flow channel 1 and the flow channel 2, the valve core is movably connected to the water-containing cavity and blocks the inner end of the flow channel 1, and the spring is arranged vertically and elastically acts between the valve core and the water spray joint. The flow channel 2 structure arranged in the valve body of the one-way valve cooperates with the flow channel 1 structure in the water spray joint to make the flow path of the water flow longer to ensure the flow speed of the water flow, and at the same time, under the cooperation of the valve core and the spring, the flow channel 2 can be blocked in time to prevent the gas and liquid in the cavity from flowing back outward from the flow channel 2.

[0010] In the above-mentioned atomization structure of the carbonated water tank, the valve core is columnar, a water groove is provided at the lower end of the valve core, and a plurality of water holes connected to the water groove are provided on the outer wall of the valve core in the circumferential direction. The upper end of the spring extends into the water groove and abuts against the bottom wall of the water groove, and the lower end abuts against the outer wall of the upper end of the water spray joint. The water groove on the valve core can fully guide the spring to avoid the lateral displacement of the valve core caused by its bias force. At the same time, the water groove cooperates with the water hole to prevent the spring from moving downward under the action of water pressure to block the upper end of the flow channel 1, so as to ensure that the water flow can pass through the flow channel 2, the water storage cavity, the water hole, the water groove and the flow channel 1 in sequence and finally enter the cavity of the tank body, effectively ensuring the smooth delivery of pure water.

[0011] In the above-mentioned atomization structure of the carbonated water tank, the upper end of the valve core is provided with an installation groove, and a rubber pad is embedded in the installation groove, and the rubber pad is pressed against the inner wall of the top of the water containing chamber and blocks the two inner ends of the flow channel. Through the provision of the rubber pad, it can be pressed against the inner wall of the top of the water containing chamber to block the two inner ends of the flow channel, effectively preventing the backflow of pure water, and at the same time, the rubber pad is limited by the installation groove to ensure the installation stability of the rubber pad.

[0012] In the above-mentioned atomization structure of the carbonated water tank, the lower end of the valve body is screwed to the upper end of the water spray joint, and a sealing ring is provided between the lower end of the valve body and the upper end of the water spray joint to ensure that the one-way valve and the water spray joint are firmly connected and the sealing between the two is ensured.

[0013] In the above-mentioned atomization structure of the carbonated water tank, the atomization structure further includes a connection cap and a connection sleeve having a flow channel 3 therein, the flow channel 3 is connected to the flow channel 2, the connection cap is screwed to the upper end of the valve body and the connection sleeve is pressed against the valve body. This further ensures that the water path is longer, ensures the delivery speed of pure water, and also ensures that the connection cap can be disassembled and replaced, and can be used in different external pipelines.

[0014] In the above-mentioned atomization structure of the carbonated water tank, an annular sealing gasket is provided between the connecting sleeve and the upper end of the valve body, thereby ensuring the sealing between the connecting cap and the one-way valve.

[0015] Compared with the prior art, the atomization structure of the carbonated water tank has the following advantages:

[0016] Under the action of the one-way valve, the backflow of purified water is avoided, and the purified water is input into the cavity of the tank body through the one-way valve, flow channel 1 and the water spray hole at the lower end of the water spray joint in sequence. Under the guidance of the inner wall of flow channel 1 and the existence of gravity, the purified water can impact the inner wall of the cavity when it is input into the cavity, so that the purified water is refined into particles or even mist. At this time, the purified water can be more fully mixed with the carbon dioxide in the cavity to ensure that the carbonation effect of the purified water is more sufficient.

The water spray joint 3 is fixedly connected to the top of the tank body 1 and the lower end extends into the cavity 11. A plurality of water spray holes 32 are opened circumferentially on the outer side wall of the lower end of the water spray joint 3, and each water spray hole 32 is directly opposite to the inner wall of the cavity 11.

[0028] Combination Figure 4 The one-way valve 2 includes a valve body 23, a valve core 22 and a spring 21. The valve body 23 is columnar and has a mounting groove 223 at the lower end. The upper end of the valve body 23 has a flow channel 231 vertically opened. The lower end of the valve body 23 is screwed to the upper end of the water spray joint 3, so that a water-containing cavity 232 is formed between the two to connect the flow channel 1 31 and the flow channel 2 231. A sealing ring 4 is provided between the lower end of the valve body 23 and the upper end of the water spray joint 3 to block the gap between the two.

The upper end of the spring 21 extends into the water groove 221 and abuts against the inner bottom wall of the water groove 221, and the lower end abuts against the upper end of the water spray joint 3. As a further solution, a limiting groove arranged around the upper end of the flow channel 31 can also be opened at the upper end of the water spray joint 3, and the lower end of the spring 21 extends into the limiting groove and abuts against the bottom wall of the limiting groove, thereby limiting the two ends of the spring 21 to prevent the force acting on the valve core 22 from being offset when it is extended and retracted.

[0029] Combination Figure 5 The connecting sleeve 6 is columnar and has a flow channel three 61 arranged vertically inside. The outer wall at the bottom of the connecting sleeve 6 has a pressing edge protruding outward.
