Description

Technical Field

[0001] The present invention relates to the field of bubble water preparation, in particular to a safe manual pressure-releasing bubble water machine that prevents accidental touching. Background Art

[0002] Sparkling water is a drinkable aqueous solution created by injecting food-grade carbon dioxide gas directly into water through a sparkling water machine. Sparkling water has health benefits such as helping to regulate the body's acid-base balance and enhancing gastrointestinal vitality. At the same time, its unique taste is gradually becoming popular among young people. Natural sparkling water is currently relatively rare, and the sparkling water on the market is basically artificially produced by sparkling water machines. There are two common types of sparkling water machines in the existing technology. One is a household desktop sparkling water machine equipped with a large gas cylinder that can prepare large-capacity bottles of sparkling water for family drinking. However, the cost of replacing the gas cylinder is high, and it is inconvenient to carry. The other is a portable sparkling water machine equipped with a smaller gas cartridge that can prepare small-capacity bottles of sparkling water. It is convenient to carry and use outside and has a low cost.

[0003] However, the portable sparkling water machine adopts the traditional threaded pressure bullet method, which has a relatively complex structure and increases the cost. In addition, most of the portable sparkling water machines on the market use the method of rotating the upper cover counterclockwise and squeezing the pressure relief valve downward to release the air. This has a certain probability of causing the pressure relief valve to not be squeezed into place, resulting in an unsafe factor that the bubble-rich soda will gush out through the air hole punctured by the ejector pin when the bullet is withdrawn. In addition, most of the push-type pressure relief valves on the market generally have push-type pressure relief valves. When the upper cover is rotated clockwise to puncture the gas cartridge, people may accidentally touch the push-type valve, which is inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a safe manual pressure relief type sparkling water machine that prevents accidental touching, so as to solve the problem raised in the above background technology that the portable sparkling water machine adopts the traditional threaded pressure spring method, which has a relatively complex structure and increases the cost, and most of the ones on the market rotate the upper cover counterclockwise and squeeze the pressure relief valve downward to deflate the air. This will cause a certain probability that the pressure relief valve will not be squeezed into place, resulting in an unsafe factor that the bubble-rich soda will gush out through the air hole punctured by the ejector pin when the bullet is withdrawn, and most of the press-type pressure relief valves on the market are general press-type pressure relief valves. When the upper cover is rotated clockwise to puncture the air cartridge, the human hand may accidentally touch the press-type valve, which is inconvenient to use.

[0006] As a preferred technical solution of the present invention, an annular wavy bone extrusion strip is provided on the top of the inner wall of the upper cover, and an annular groove is provided on the top of the gas bullet accommodating chamber. The annular wavy bone extrusion strip and the annular groove match each other. When rotating, the annular wavy bone extrusion strip provided on the inner wall is driven by the upper cover to extrude the inflated gas bullet downward, and then the inflated gas bullet moves downward in the gas bullet accommodating chamber and is finally punctured by the puncture needle.

[0007] As a preferred technical solution of the present invention, a bullet feed port is provided on one side of the upper cover, and the top of the gas bullet accommodating chamber is in contact with the surface of the inner wall of the upper cover, so that the bullet feed port is convenient for loading inflatable gas bullets.

[0008] As a preferred technical solution of the present invention, the needle head of the puncture needle is provided with a fine hole, which facilitates the passage of carbon dioxide gas.

[0009] As a preferred technical solution of the present invention, the bottom thread of the pressure relief valve body is connected to an air injection pipe, the bottom of the air injection pipe extends to the interior of the water bottle, the inflatable air bomb moves downward in the air bomb accommodating chamber, the inflatable air bomb is punctured by a puncture pin, and the carbon dioxide gas passes through the puncture pin and the air injection pipe into the water bottle filled with water.

[0010] As a preferred technical solution of the present invention, the first spring is connected to the inner wall of the pressure relief valve body, one side of the pressure relief block is clamped with the top of the pressure relief rod, and the pressure relief block on one side of the shell body is slid downward, and the pressure relief block squeezes the pressure relief rod downward, pressing the position of the pressure relief valve body downward, and then the puncture pin connected to the pressure relief valve body is pressed downward.

[0011] As a preferred technical solution of the present invention, the side of the pressure relief valve body away from the sleeve is threadedly connected to a pressure maintaining seat, the top of the pressure maintaining seat is connected to a second spring, the top of the second spring is connected to the inner wall of the shell body, and the second spring and the pressure maintaining seat can assist the pressure relief valve body in resetting when the external force disappears.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-8 The present invention provides a safe manual pressure relief type sparkling water machine that prevents accidental touch, comprising a shell body 1, the top of the shell body 1 being rotatably connected to the upper cover 2, a threaded internal thread 9 being installed at the bottom of the inner wall of the shell body 1, the bottom of the threaded internal thread 9 being threadedly connected to the water bottle 3, a pressure relief valve body 6 being provided at the top of the threaded internal thread 9, a puncture ejector pin 8 being threadedly connected to one side of the top of the pressure relief valve body 6, an air cartridge accommodating chamber 4 being provided at the top of the inner wall of the shell body 1, an inflatable air cartridge 5 being placed inside the air cartridge accommodating chamber 4, and the bottom of the air cartridge accommodating chamber 4 being snap-connected to the top of the puncture ejector pin 8, a sliding hole 11 being provided in the middle of one side of the puncture ejector pin 8, and the inside of the sliding hole 11 A pressure relief block 10 is provided, and a sleeve 12 is threadedly connected to one side of the pressure relief valve body 6. A pressure relief rod 13 is inserted into the middle of the sleeve 12, and a first spring 14 is installed at the bottom of the pressure relief rod 13. After the inflatable gas bomb 5 is loaded into the gas bomb accommodating chamber 4, the upper cover 2 is held and rotated clockwise. During rotation, the annular wave bone extrusion strip 17 arranged on the inner wall is driven by the upper cover 2 to squeeze the inflatable gas bomb 5 downward, and then the inflatable gas bomb 5 moves downward in the gas bomb accommodating chamber 4, and is finally punctured by the puncture needle 8. The carbon dioxide gas in the inflatable gas bomb 5 passes through the fine hole 21 of the puncture needle 8 and the gas injection pipe 7 at the bottom of the pressure relief valve body 6 and leads to the water bottle 3 filled with water.

[0026] The top of the inner wall of the upper cover 2 is provided with an annular wavy bone extrusion strip 17, and the top of the gas bullet accommodating chamber 4 is provided with an annular groove 19. The annular wavy bone extrusion strip 17 and the annular groove 19 match each other. A bullet inlet 18 is provided on one side of the upper cover 2. The top of the gas bullet accommodating chamber 4 fits with the surface of the inner wall of the upper cover 2. The needle head of the puncture pin 8 is provided with a fine hole 21. The bottom thread of the pressure relief valve body 6 is connected to the air injection pipe 7. The bottom of the air injection pipe 7 extends to the interior of the water bottle 3. The inflatable gas bullet 5 is punctured by the puncture pin 8, and the carbon dioxide gas passes through the fine hole 21 that punctures the pin 8 and the air injection pipe 7 at the bottom of the pressure relief valve body 6 into the water bottle 3 filled with water, inflating the water to form bubble water, and preparing the bubble water.

[0027] The first spring 14 is connected to the inner wall of the pressure relief valve body 6, and one side of the pressure relief block 10 is clamped with the top of the pressure relief rod 13. The side of the pressure relief valve body 6 away from the sleeve 12 is threadedly connected to a pressure maintaining seat 15, and the top of the pressure maintaining seat 15 is connected to a second spring 16. The top of the second spring 16 is connected to the inner wall of the outer shell body 1. A groove 20 is provided on the surface of the outer side of the pressure relief block 10, and the plane height of the outer shell body 1 is higher than the outer side of the pressure relief block 10. After the inflatable gas bomb 5 is punctured, after a period of time, the pressure relief block 10 on one side of the outer shell body 1 slides downward, and the pressure relief block 10 squeezes the pressure relief rod 13 downward. The pressure relief rod 13 cooperates with the first spring 14 to press the position of the pressure relief valve body 6, and then the puncture pin 8 connected to the pressure relief valve body 6 is pressed down, so that the carbon dioxide gas that has not dissolved in the water in the water bottle 3 is discharged from the water bottle 3, preventing the bubble-rich soda from gushing out due to excessive air pressure when the water bottle 3 is opened.

[0028] When in use, the present invention provides a safe manual pressure relief type sparkling water machine that prevents accidental touch. The bullet inlet 18 of the upper cover 2 is aligned with the material port position of the gas bullet storage chamber 4. After the inflatable gas bullet 5 is loaded into the gas bullet storage chamber 4, the upper cover 2 is held and rotated clockwise. During the rotation, the annular wave bone extrusion strip 17 provided on the inner wall is driven by the upper cover 2 to squeeze the inflatable gas bullet 5 downward. The inflatable gas bullet 5 then moves downward in the gas bullet storage chamber 4 and is finally punctured by the puncture needle 8. The carbon dioxide gas in the inflatable gas bullet 5 passes through the fine hole 21 of the puncture needle 8 and the gas injection pipe 7 at the bottom of the pressure relief valve body 6 into the water bottle 3 filled with water, thereby inflating the water to form sparkling water. Compared with the traditional threaded bullet pressing method, this bullet feeding and pressing method has a simpler structure and lower cost.

[0029] After the inflatable gas bomb 5 is punctured, carbon dioxide gas is injected into the water bottle 3. After a period of time, the pressure relief block 10 on one side of the outer shell body 1 slides downward, and the pressure relief block 10 squeezes the pressure relief rod 13 downward. The pressure relief rod 13 cooperates with the first spring 14 to press the position of the pressure relief valve body 6 downward, and then the puncture ejector pin 8 connected to the pressure relief valve body 6 is pressed downward, so that the carbon dioxide gas that has not dissolved in the water in the water bottle 3 is discharged from the water bottle 3, preventing the water bottle 3 from being opened with excessive air pressure causing the soda rich in bubbles to gush out. This manual pressure relief method is different from most of the methods on the market that deflate by rotating the upper cover 2 counterclockwise to squeeze the pressure relief valve downward, avoiding the pressure relief valve not being squeezed into place, resulting in the uneasy feeling of soda rich in bubbles gushing out through the air hole of the ejector pin when the bomb is withdrawn. All factors are taken into consideration. The unsafe factor of the bullet being withdrawn when rotating counterclockwise is solved by manually sliding the pressure relief block 10 downward. This manual pressure relief method is also different from most push-type pressure relief valves on the market. When the upper cover 2 of the general push-type pressure relief valve is rotated clockwise to puncture the gas bullet, the human hand may accidentally touch the push-type valve, resulting in abnormal pressure maintenance in the water bottle 3 when the gas bullet is punctured. The air pressure of the gas bullet will cause the air and water in the water bottle 3 to rush out through the manual pressure relief valve, resulting in insufficient carbonation reaction between carbon dioxide and water. This manual pressure relief method slides up and down to relieve pressure, and the probability of accidental touch is much lower than that of most push-type pressure relief valves. In addition, the pressure relief block 10 is not higher than the plane height of the shell body 1, that is, the pressure relief block 10 is in the sliding hole 11, which is easy to use.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
