Description

Technical Field

[0001] The present application relates to the technical field of bubble water machines, and in particular to a split-type bubble water machine. Background Art

[0002] Sparkling water machines pressurize carbon dioxide into a water bottle to create sparkling water. Traditionally, the bottle is open, requiring the water to be consumed immediately after preparation. Over time, the carbon dioxide in the water will gradually escape, losing its original flavor.

[0003] To this end, Chinese utility model patent CN 204394246 U discloses a split-type beverage dispenser, in which an air intake control device is installed at the mouth of the beverage bottle. The device is detachably connected to the main machine via an air guide. The air intake control device has a one-way valve to achieve one-way air intake. As a result, after the beverage bottle is removed, the carbon dioxide in the bottle remains in the beverage and does not overflow from the bottle mouth, maintaining the taste for a long time. However, when filling the beverage bottle with air, this solution requires first flipping the air guide device outward and then pressing the air outlet drive device. After filling, the air guide device needs to be flipped again before the beverage bottle can be removed, resulting in a complex structure and cumbersome operation. Utility Model Content

[0054] In the existing split beverage machine, when inflating the beverage bottle, it is necessary to first flip the air guide device outward and then press the air outlet drive device. After the inflation is completed, the air guide device needs to be flipped again to remove the beverage bottle, which makes the structure complex and the operation cumbersome.

[0055] To this end, the present invention optimizes the structure of the button mechanism and the inflation mechanism. With a single action of the button mechanism, the cannula can be moved downward and inflated. This results in a simple structure and convenient operation. Furthermore, only when the cannula is inserted into the inlet cap can the operating lever be driven to open the inflation valve for inflation by continuing to press the cap. During the initial period of pressing the button mechanism, the operating lever remains inactive and the inflation valve remains inactive, thus avoiding waste of carbon dioxide.

[0056] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described below 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 shall fall within the scope of protection of the present invention.

[0057] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, several preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

Obviously, the use of the corresponding directional words does not constitute a limitation on the scope of protection of this scheme.

[0059] See Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the split-type bubble water machine provided by the utility model. Figure 2 for Figure 1 The assembly diagram of the split-type sparkling water machine and the beverage bottle is shown. Figure 3 for Figure 1 A cross-sectional view of the assembled split-type sparkling water machine and beverage bottle is shown.

[0060] like Figure 1 、 Figure 2 、 Figure 3 As shown, the present application provides a split-type sparkling water machine, and the main body 200 is provided with a water bottle connecting seat 250 that is detachably connected to the drinking water bottle 100. The drinking water bottle 100 can be installed on the water bottle connecting seat 250, and carbon dioxide gas is injected into the drinking water bottle 100 to prepare sparkling water. After the sparkling water is prepared, the drinking water bottle 100 can be removed and carried with you, so that you can drink the sparkling water anytime and anywhere, which is convenient to use.

[0061] The main unit 200 includes a base 210, one end of which is provided with a body 220, which houses a carbon dioxide gas cylinder 230. A head 240 is located above the body 220. The head 240 is horizontally arranged, with its other end extending outward from the body 220 to form an extension. A water bottle connector 250 is fixedly mounted on the bottom surface of the extension.

[0062] The water bottle connector 250 is provided with two horizontally parallel, opposed slide rails 251. The air inlet cap 110 of the drinking water bottle 100 is provided with two mounting grooves 1113 on its outer surface, which mate with the two slide rails 251. The slide rails 251 slidably engage with the mounting grooves 1113, allowing the air inlet cap 110 and the drinking water bottle 100 to be installed or removed from the water bottle connector 250, achieving a detachable connection between the drinking water bottle 100 and the main unit 200.

[0063] like Figure 4 、 Figure 5 As shown, the rear ends of the two slide rails 251 of the water bottle connecting seat 250 are fixedly connected to the top plate 253 through the surrounding plate 252, and the gas inlet bottle cover 110 can be slidably assembled and unassembled through the gaps formed at the front ends of the two slide rails 251.

[0064] Recombination Figure 3As shown, in the present application, in order to prevent the beverage bottle 100 from falling off after installation, a first magnet 1114 is provided in the air inlet bottle cap 110, and a second magnet 254 is provided on the outer wall of the enclosure 252. After the air inlet bottle cap 110 and the beverage bottle 100 are fixed on the bottle connecting seat 250, the first magnet 1114 and the second magnet 254 are magnetically fixed to each other.

[0065] An inflation mechanism 260, an operating rod 270 and a button mechanism 280 are provided in the machine head 240, wherein the top of the button mechanism 280 passes through the machine head 240 upward, and the inflation mechanism 260 is connected to the carbon dioxide storage cylinder 230. The inflation mechanism 260 can be controlled by the button mechanism 280 and the operating rod 270 to add the carbon dioxide gas in the carbon dioxide storage cylinder 230 into the beverage bottle 100 to prepare sparkling water.

[0066] like Figure 6 、 Figure 7 As shown, the inflation mechanism 260 includes an inflation valve 261, which is mounted on an inflation seat 262. The inflation seat 262 is provided with an inflation connector 263, which is in communication with the inflation valve 261. The inflation connector 263 is connected to the button mechanism 280 via an inflation tube 264. The bottle mouth of the carbon dioxide storage cylinder 230 is connected to the inflation seat 262. The inflation valve 261 can be opened or closed by operating the lever 270, so that the carbon dioxide gas in the carbon dioxide storage cylinder 230 is injected into the beverage bottle 100 through the button mechanism 280 to produce sparkling water.

[0067] Recombination Figure 8 、 Figure 9 As shown, the key mechanism 280 includes a pressing cover 281 and a floating head 282 , and the pressing cover 281 is slidably set in the guide hole on the machine head 240 .

[0068] A guide post 241 is provided on the handpiece 240, located above the water bottle connector 250. A floating head 282 is slidably mounted on the guide post 241 and equipped with a return spring that provides an upward force. The floating head 282 is restrained by a stop screw 283 above the guide post 241 to prevent it from falling off. The inlet end of the inflation tube 264 is connected to the inflation connector 263, while the outlet end is fixed to the floating head 282. A cannula 2641 is provided at the outlet end of the inflation tube 264, extending through the floating head 282 and the handpiece 240.

[0069] One end of the operating rod 270 facing the carbon dioxide gas storage cylinder 230 is hinged to the inflation seat 262 , and the end of the operating rod 270 facing the drinking water bottle 100 is a free end and is provided with an eight-shaped branch 271 .

[0070] like Figure 10 、 Figure 11As shown, the bottom surface of the pressure cap 281 is provided with two pressure posts 2811 and two sets of pressure blocks 2812. The pressure posts 2811 correspond to the contact points on the floating head 282 and are used to press the floating head 282 downward. The pressure blocks 2812 are arranged opposite the ends of the figure-eight branches 271 and are used to press the operating rod 270 downward. The pressure posts 2811 are longer than the pressure blocks 2812, so that the pressing stroke of the floating head 282 is greater than the pressing stroke of the operating rod 270. The pressure posts 2811 press the floating head 282 and insert the cannula 2641 into the gas inlet bottle cap 110, while the pressure blocks 2812 press against the top surfaces of the figure-eight branches 271. At this point, continuing to press the cap 281, pressing the operating rod 270, opens the inflation valve 261, and the carbon dioxide gas in the carbon dioxide storage cylinder 230 enters the beverage bottle 100 through the inflation tube 264, producing sparkling water.

[0071] In the present application, the length of the pressure column 2811 on the pressure cap 281 is greater than the pressure block 2812, so that the pressing stroke of the floating head 282 is greater than the pressing stroke of the operating rod 270. When the pressure cap 281 is pressed, only when the cannula 2641 is inserted into the gas inlet bottle cap 110, the pressure cap 281 is continued to be pressed, and the operating rod 270 opens the inflation valve 261. During the period before the pressure cap 281 is pressed, when the cannula 2641 is not inserted into the gas inlet bottle cap 110, the operating rod 270 does not move and the inflation valve 261 will not be opened, thereby avoiding the waste of carbon dioxide.

[0072] In addition, in the present application, an end of the operating rod 270 facing the beverage bottle 100 is provided with an eight-shaped branch 271, and the eight-shaped branch of the operating rod is pressed by two pressing blocks, thereby improving the stability of the operation.

[0073] Furthermore, in the present application, the operating rod 270 has a longer length, which can more accurately control the opening and closing of the inflation valve.

[0074] like Figure 12 As shown, a sleeve 2821 is provided on the bottom surface of the floating head 282 surrounding the insert tube 2641, and a guide angle is provided at the lower end of the sleeve 2821, which is adapted to the tapered hole at the upper end of the air inlet on the beverage bottle 100. The floating head 282 moves downward, and when the insert tube 2641 is inserted into the air inlet bottle cap 110, the sleeve 2821 is pressed against the side wall of the tapered hole of the air inlet on the beverage bottle 100, thereby achieving sealing and preventing carbon dioxide gas from overflowing.

[0075] The present application also provides a beverage bottle 100 for use with the host 200 of the above-mentioned split-type sparkling water machine.

[0076] like Figure 13 、 Figure 14As shown, the beverage bottle includes an air inlet bottle cap 110 and a bottle body 120, wherein the air inlet bottle cap 110 is detachably arranged on the bottle mouth of the bottle body 120. An exhaust switch 130 is provided on the air inlet bottle cap 110 for realizing the exhaust function of the bottle body 120 so as to safely remove the air inlet bottle cap 110 from the bottle body 120.

[0077] like Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 As shown, the air intake bottle cover 110 includes an upper cover 111 and a lower cover 112. The upper cover 111 is fixed to the lower cover 112 to form a receiving chamber, and the air intake control device 140 is fixed in the receiving chamber. Specifically, the upper cover 111 is provided with a plurality of fixing posts 1111, and the lower cover 112 is provided with fixing holes 1121 corresponding to the fixing posts 1111. Bolts pass through the fixing holes 1121 and are fixed to the lower ends of the fixing posts 1111, thereby clamping the air intake control device 140 in the receiving chamber.

[0078] A notch 1112 is defined on the upper cover 111 , and the exhaust switch 130 is installed in the notch 1112 .

[0079] Two mounting grooves 1113 for sliding connection with the split-type bubble water machine are provided on the outer surface of the upper cover 111. The two mounting grooves 1113 are arranged horizontally and parallel to each other to facilitate the detachable connection between the beverage bottle and the split-type bubble water machine.

[0080] A first magnet 1114 is provided in the upper cover 111. After the beverage bottle is installed, it is magnetically fixed to the split-type sparkling water machine through the first magnet 1114. The beverage bottle will not fall off and can be easily removed.

[0081] The air intake control device 140 includes a water bottle interface 141, a sealing cap 142, and an air intake cannula 143. The water bottle interface 141 is internally threaded for threaded connection with the bottle mouth of the bottle body 120. The lower end of the lower cover 112 is provided with an opening for inserting the bottle mouth of the beverage bottle into the water bottle interface 141. The water bottle interface 141 is fixed within the accommodating chamber. The sealing cap 142 is fixed to the water bottle interface 141. An air intake hole 144 is centrally located in the sealing cap 142. The air intake cannula 143 is threadedly connected to the lower end of the air intake hole 144. An air intake check valve 145 is installed at the upper end of the air intake cannula 143. A filter device 146 is also provided between the top surface of the air intake cannula 143 and the sealing cap 142. A sealing ring 147 is also provided between the water bottle interface 141 and the sealing cap 142 to ensure a sealed bottle mouth.

[0082] like Figure 19 、 Figure 20 、 Figure 21 、 Figure 22As shown, the exhaust switch 130 includes a base 131, a rotating base 132, a sliding cover 133, and an exhaust valve. The base 131 is fixed to the top surface of the cover 142. The exhaust valve is provided on the cover 142 to realize the exhaust function of the bottle body 120. It consists of a valve stem 134 sleeved on an exhaust valve core 135. The upper end of the valve stem 134 of the exhaust valve is arranged to extend through the base 131, and the lower end of the valve stem 134 is sleeved with a spring 136 to reset the exhaust valve core 135 downward.

[0083] The base 131 is provided with a rotating shaft 137, on which the rotating seat 132 is rotatably mounted. The sliding cover 133 is disposed above the rotating seat 132. Slide grooves 1321 are respectively provided on the two side walls of the rotating seat 132. Sliders 1332 are provided on the side walls of the sliding cover 133 to mate with the slide grooves 1321. Sliders 1332 are slidably mounted within the slide grooves 1321 and can slide along the slide grooves 1321, ensuring both guidance and reliability of the sliding movement and limiting the travel distance. A bayonet 1323 is provided at the front end of the rotating seat 132. A constricted portion is provided at the upper end of the valve stem 134 and is secured in place within the bayonet 1323.

[0084] The rotating seat 132 is located between the two side walls of the sliding cover 133. The two side walls of the sliding cover 133 are respectively provided with long holes 1331. The rotating shaft 137 is set through the two long holes 1331, so that the sliding cover 133 can slide along the long holes 1331 and extend and retract relative to the upper cover 111, and define its unlocking position and locking position.

[0085] The front lower part of the sliding cover 133 is provided with a claw 1333. When the sliding cover 133 is pushed inward, the claw 1333 can extend under the top wall of the upper cover 111. At this time, the sliding cover 133 cannot be rotated due to the obstruction of the upper cover 111. The exhaust valve is in a closed state and cannot be opened. The sliding cover is in a locked position. Figure 23 When the sliding cover 133 is pulled outward and the claw 1333 is separated from the upper cover 111, it is in the unlocked position. At this time, the lower end of the sliding cover 133 can rotate under the action of the downward pressure, and drive the rotating seat 132 to rotate, and pull up the valve stem 134 of the exhaust valve to open the exhaust valve. Figure 24 shown.

[0086] Specifically, the outer end of the sliding cover 133 is pressed down, and the sliding cover 133 rotates around the rotating shaft 137. At the same time, the slider 1332 hooks the sliding groove 1321, driving the rotating seat 132 to rotate around the rotating shaft 137. The bayonet 1323 on the rotating seat 132 clamps the valve stem 134 and moves upward, the exhaust valve opens, and the carbon dioxide gas in the bottle body 120 can be discharged through the exhaust valve.

[0087] The sealing cap 142 is also provided with a safety valve 148 and a pressure relief valve 149 to prevent the air pressure in the bottle body 120 from being too high, thereby ensuring safety in use.

[0088] In the present invention, the air intake check valve 145 includes an air intake valve core 1451, which can be implemented in two structural forms.

[0089] like Figure 25 、 Figure 26 、 Figure 27 As shown, in the first structural form, an air intake valve core 1451 is disposed within the cannula air inlet at the upper end of the air intake cannula 143, and is provided with an air intake check valve 145. The air intake valve core 1451 is in the shape of a stepped shaft, with a sealing ring 1452 provided on the outer circumference of the upper portion and an elastic hose 1453 sleeved on the outer circumference of the lower portion. The air intake valve core 1451 is provided with a central blind hole, the upper end of which is connected to the cannula air inlet. A radial air hole 1454 is formed on the sidewall of the central blind hole, and the elastic hose 1453 is provided to cover the radial air hole 1454. An air guide cover 1455 is provided on the lower end surface of the air intake valve core 1451. The air guide cover 1455 has a central countersunk hole and multiple radial grooves 1456. The radial grooves 1456 are connected to the central countersunk hole and the outer surface of the air guide cover 1455.

[0090] When the drinking cup is not being inflated, the elastic hose 1453 clings to the radial air hole 1454, closing the air inlet check valve 145. When the drinking cup is being inflated and the air pressure in the air inlet hole 144 exceeds a set value, the air pressure deforms the elastic hose 1453 through the radial air hole 1454, causing the air to flow out through the gap between the elastic hose 1453 and the lower outer circumferential surface of the air inlet valve core 1451, then pass through the radial groove 1456 and the central countersunk hole on the air guide cover 1455, entering the air inlet cannula 143, and the air inlet check valve 1455 opens.

[0091] like Figure 28 As shown, in the second structural form, the air intake valve core 1451 is arranged in the step hole at the lower end of the air intake nozzle 1457, the lower end of the air intake nozzle 1457 is arranged on the cover 142, the air inlet 144 is arranged on the air intake nozzle 1457, and is connected with the air intake tube 143, and the lower end of the air intake valve core 1451 is sleeved with a valve core spring 1458, which is used to provide the elastic force of the air intake valve core 1451 to press the step surface of the step hole of the air intake nozzle 1457 upward to close the air intake nozzle 1457.

[0092] When the drinking cup is not being inflated, the valve core spring 1458 causes the air inlet valve core 1451 to press upward against the stepped surface of the stepped hole at the lower end of the air inlet nozzle 1457, closing the air inlet check valve 145. When the drinking cup is being inflated and the air pressure in the air inlet hole 144 exceeds the set value, the pressure of the valve core spring 1458 is overcome, causing the air inlet valve core 1451 to move downward, and the air inlet check valve 1455 to open.

[0093] A guide tube 1459 may be sleeved on the outer circumferential surface of the intake valve core 1451 . The guide tube 1459 is made of a material with a harder hardness than the intake valve core 1451 and is not easily deformed, thereby allowing the intake valve core 1451 to move up and down more smoothly.

[0094] Based on the description of the above specific embodiments, the split-type sparkling water machine provided by the present invention has the following advantages compared with the prior art:

[0095] The tube can be moved down and inflated only by one action of the button mechanism. After the inflation is completed, the beverage bottle can be directly removed, which makes the structure simple and the operation convenient.

[0096] Only when the cannula is inserted into the gas inlet bottle cap, continuing to press the cap can drive the operating lever to open the inflation valve for inflation. During the first period of time when the button mechanism is pressed, the operating lever will not move and the inflation valve will not be opened, thus avoiding waste of carbon dioxide.

[0097] Third, the operating lever is longer, enabling more precise control of the opening and closing of the inflation valve. Furthermore, the operating lever has an eight-shaped branch at the end facing the beverage bottle, which is pressed by two pressing blocks, improving operational stability.

[0098] Fourth, a first magnet is provided in the air inlet bottle cap, and a second magnet is provided on the water bottle connecting seat. After the beverage bottle is installed, it is fixed by magnetic attraction between the first magnet and the second magnet. The beverage bottle will not fall off and can be easily removed.

[0099] Fifth, the exhaust switch of the beverage bottle has a self-locking function, which can prevent the exhaust switch from accidentally opening and causing the carbon dioxide gas in the bottle to overflow.

[0100] Finally, it should be noted that the terms "comprise," "include," or any other variations thereof, as used herein, are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0101] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any structural changes with the same or similar technical solutions as the present invention fall within the scope of protection of the present invention.
