[0050] 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.

[0051] Existing beverage bottles with air intake caps (air intake control devices) can be vented by lifting the exhaust ring to move the exhaust valve core upward to remove the air intake cap. However, this design is prone to accidental deflation due to the exhaust ring, resulting in poor reliability.

[0052] The present application scheme improves the air intake bottle cap. The improved air intake bottle cap has an exhaust switch comprising a rotating seat and a sliding cover with two layers. Pulling the sliding cover horizontally outwards unlocks it. Pressing down on the outer end of the sliding cover drives the inner end of the rotating seat to tilt upwards, causing the valve stem of the exhaust valve to move upwards and the exhaust valve to open. The sliding cover is rotated to the horizontal position to close the exhaust valve. At the same time, the sliding cover is pushed inwards. The claws on the sliding cover extend under the top wall of the upper cover. The sliding cover cannot rotate and the exhaust valve cannot open, thus achieving a locking function. When the beverage bottle is carried, the sliding cover is pushed to the inner end to close the exhaust valve and lock it. The sliding cover and the rotating seat cannot rotate, so there will be no accidental deflation or misoperation, thereby improving reliability.

[0053] 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.

[0054] It should be noted that the directional words such as "inside, outside", "front, back" and "left, right" in this article are expressed based on the product usage status. Obviously, the use of the corresponding directional words does not constitute a limitation on the scope of protection of this scheme.

[0055] like Figure 1 、 Figure 2 As shown, the present application provides a beverage bottle for a split-type sparkling water dispenser, comprising an air inlet cap 110 and a bottle body 120. The air inlet cap 110 is detachably mounted on the mouth of the bottle body 120. For example, the mouth of the bottle body 120 is threadedly connected to the air inlet cap 110 to achieve detachable functionality. The air inlet cap 110 is provided with a vent switch 130 for venting the bottle body 120, allowing for safe removal of the air inlet cap 110 from the bottle body 120.

[0056] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 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.

[0057] A notch 1112 is defined on the upper cover 111 , and the exhaust switch 130 is installed in the notch 1112 .

[0058] 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.

[0059] 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.

[0060] 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 to the bottle mouth of the bottle body 120. The lower end of the lower cover 112 is provided with an opening for inserting the mouth of the beverage bottle into the water bottle interface 141. 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 located 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.

[0061] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As 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.

[0062] 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.

[0063] 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.

[0064] 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 11 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 12 shown.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] like Figure 13 、 Figure 14 、 Figure 15As 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.

[0069] 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.

[0070] like Figure 16 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 intake hole 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.

[0071] 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.

[0072] 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.

[0073] Based on the description of the above specific embodiments, the beverage bottle and the air inlet bottle cap for the split-type sparkling water machine provided by the present invention have the following advantages compared with the prior art:

[0074] The exhaust switch on the intake bottle cap consists of a two-layer structure: a rotating base and a sliding cover. Pulling the sliding cover outward unlocks it. Pressing down on the outer end of the sliding cover causes the inner end of the rotating base to tilt upward, moving the exhaust valve stem upward and opening the exhaust valve. Pushing the sliding cover inward causes the claws to extend under the top wall of the upper cover, preventing further rotation and locking the cover. When the bottle is carried, pushing the sliding cover inward closes and locks the exhaust valve, preventing accidental deflation and misoperation, thus improving reliability.

[0075] Second, two mounting grooves for sliding connection with the split-type bubble water machine are provided on the outer surface of the upper cover, which can facilitate the detachable connection between the beverage bottle and the split-type bubble water machine.

[0076] Third, a first magnet is provided in the upper cover. After the beverage bottle is installed, it is fixed to the split-type sparkling water machine by magnetic attraction through the first magnet. The beverage bottle will not fall off and can be easily removed.

[0077] 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.

[0078] 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.
