[0020] 1 to 11, an air intake automatic reset air bubble water maker, A master unit 10 is provided with a slave unit 20 on one side and an intake body 40 on which a cylinder connection port is provided; an intake pressure rod (50) installed on the main unit (10), positioned on the surface of the intake rod, for driving and pressing down the intake rod, and having a through hole (51) penetrating vertically; an air passage body 30 installed on the sub-unit 20, the air passage body 30 having a water bottle joint installed at its bottom, a master air passage channel connected to the water bottle joint and the intake channel installed, an air pressure channel 32 connected to the water bottle joint installed at its front end, and an air pressure cavity 31 with an air pressure hole 34 installed at its rear end; an air pressure valve body 35 that is installed in the air pressure cavity 31 and has an air pressure valve rod 351 installed at its rear end to extend along the air pressure hole 34 to the outside of the air passage body 30; an intake connecting rod hook 53 pivotally mounted in the parent unit 10, having an upper end provided with a hook body 54 facing the through-hole 51, and a lower end serving as a driving end directly facing the air pressure valve rod 351, and having a second reset device 55 installed thereon; The intake body 40 is provided with an intake channel extending to a cylinder connection port and an intake rod for pressing a carbon dioxide gas cylinder. A button 52 for driving and moving the intake pressure rod 50 is provided on the surface of the main unit 10. The air pressure valve body 35 is provided with a first reset device 36 that drives the air pressure valve body 35 to seal the air pressure channel 32; A guide slope is provided on the surface of the hook body 54 and / or the lower end of the through hole 51, and when the intake pressure rod 50 is pressed down, the upper end of the intake connecting rod hook 53 passes through the through hole 51 and moves to the upper end of the through hole 51, and the hook body 54 is hooked onto the upper edge of the through hole 51.

[0021] In use, the button 52 is used to press the intake pressure rod 50, causing the intake rod to press the carbon dioxide cylinder to supply air. The carbon dioxide passes through the intake channel and the main airway channel into the aerated water bottle attached to the cylinder connection port. The intake pressure rod 50 is then driven, causing the through hole 51 and the intake connecting rod hook 53 to move relative to each other. The upper end of the intake connecting rod hook 53 is inserted into the through hole 51 and positioned above the through hole 51. The second reset device 55 then engages the hook body 54 with the upper edge of the through hole 51, fixing the intake pressure rod 50 for a long period of time. When the air pressure inside the bottle reaches a predetermined value, the air pressure is fed back to the air valve body 35 through the air channel 32, causing the air valve body 35 to move outward against the force of the first reset device 36 and further press the driving end of the air intake connecting rod hook 53, causing the air intake connecting rod hook 53 to swing, causing the hook body 54 to swing and further separate from the edge of the through-hole 51. At this time, the air intake pressure rod 50 is not restricted, so it is automatically reset and stops the air intake. The entire process of air intake and reset is operated and controlled by a mechanical structure, which is more stable.

[0022] In this embodiment, the intake pressure rod 50 and the button 52 may be installed independently or may be integrally formed.

[0023] In this embodiment, preferably, the rear end of the intake pressure rod 50 is pivotally mounted within the parent unit 10, the middle part of the intake pressure rod 50 is located above the intake rod, and the through hole 51 is installed at the tip of the intake pressure rod 50.

[0024] In order to further optimize and adjust the concentration of carbon dioxide gas filled in the aerated water bottle, preferably, an end cover 33 is screwed onto the rear end of the air pressure cavity 31, the air pressure hole 34 is installed on the end cover 33, the rear end of the first reset device 36 abuts against the inner surface of the end cover 33, a first driven gear 37 is installed on the outer periphery of the end cover 33, a shift knob 60 is installed on the surface of the sub-unit 20 or the main unit 10, and the shift knob 60 includes a first driving gear 62 that meshes with the first driven gear 37. By rotating the shift knob 60, the first driving gear 62 moves and rotates the first driven gear 37, thereby driving the end cover 33 to move back and forth in the air pressure cavity 31, and further adjusting the force of the first reset device 36 so that the air pressure valve body 35 is pressed when the air pressure in the aerated water bottle is different.

[0025] Considering that a positional deviation may occur between the first gear and the second gear, and the gear position does not match the actual pressure inside the aerated water bottle, preferably, a clutch gear set including a first clutch gear 63 and a second clutch gear 64 is installed between the first driven gear 37 and the first driving gear 62, the first clutch gear 63 is installed with a second driven tooth that is always meshed with the first driven gear 37, the second clutch gear 64 is installed with a third driven tooth that is always meshed with the first driving gear 62, and the first clutch gear 63 is installed with a second driven tooth that is always meshed with the first driving gear 62. First clutch teeth are provided on the latch gear 63, second clutch teeth that mesh with the first clutch teeth are provided on the second clutch gear 64, an elastic crimping member 65 is provided on the first clutch gear 63 or the second clutch gear 64 so that the first clutch gear 63 and the second clutch gear 64 mesh with each other, a first position limiting end that limits the rotation range of the shift knob 60 is provided on the shift knob, and a second position limiting end that limits the rotation range of the first driven gear 37 is provided on the first driven gear 37. The clutch gear set serves as a shift reset. During the actual shift reset adjustment process, the shift knob 60 is rotated fully in both directions once. If the shift is not synchronized, the first driven gear 37 rotates to a predetermined position during the rotation process and its rotation is restricted by the second position limiting end. At this time, the shift knob 60 has not yet reached the end of its stroke. As the shift knob 60 continues to rotate, a greater force is applied to the second clutch gear 64, causing the second clutch gear 64 and the first clutch gear 63 to expand against the force of the elastic pressure member 65, resulting in slippage. The shift knob 60 can then continue to rotate to the end of its stroke, until it is aligned with the position of the first driven gear 37. The slippage between the second clutch gear 64 and the first clutch gear 63 prevents damage to the first driving gear 62, the clutch gear set, and the first driven gear 37.

[0026] Preferably, the first clutch teeth are installed on the upper end surface of the first clutch gear 63, the second clutch teeth are installed on the lower end surface of the second clutch gear 64, and the elastic crimping member 65 is installed on the upper end surface of the second clutch gear 64 and presses the second clutch gear 64 downward against the upper end surface of the first clutch gear 63.

[0027] Preferably, an annular receiving groove 641 is provided on the upper end surface of the second clutch gear 64 , and the elastic pressure member 65 is a spring inserted into the annular receiving groove 641 .

[0028] The first position limiting end preferably includes a main pin body installed on the surface of the first drive gear 62 and a sub-pin body installed in the slave unit 20, and when the first drive gear 62 rotates toward either side to a limit position, the main pin body abuts against the sub-pin body. In another embodiment, the first position limiting end includes a stroke groove installed in the slave unit 20 and a stroke block located in the shift knob 60, and the stroke block is located in the stroke groove, thereby limiting the rotation range of the shift knob 60 through the stroke groove. The specific embodiment of the second position limiting end may be the same as the embodiment of the first position limiting end, or may be another undescribed embodiment.

[0029] Further optimized, preferably, a plurality of Hall sensors are installed around the periphery of the shift knob 60, a magnet 61 that engages with the Hall sensors is installed on the shift knob 60, and a shift display electrically connected to the Hall sensors is installed on the surface of the sub-unit 20 or the main unit. Further optimization is preferably achieved by installing a damping gear 90 in the parent unit 10, and installing a damping rack 91 meshing with the damping gear 90 on the intake pressure rod 50, thereby slowing down the speed when the intake pressure rod 50 is reset, thereby preventing collision noise.

[0030] The force of the intake pressure bar 50 is transmitted to the intake rod by the restoring force of the carbon dioxide cylinder needle itself, and then transmitted to the intake pressure bar 50 via the intake rod, thereby moving and resetting the intake pressure bar 50. In order to accelerate the resetting of the intake pressure bar 50 and reduce the force acting on the carbon dioxide cylinder, preferably, a third reset device is installed on the intake pressure bar 50 and a fourth reset device is installed on the intake rod.

[0031] In order to further optimize and facilitate the installation of the bubble bottle, preferably, the air passage body 30 is pivotally mounted on the sub-unit 20 so that the air passage body 30 can swing outward relative to the sub-unit 20. Accordingly, in order to prevent high pressure from occurring in the aerated water bottle during installation and when it is not fully reset to the operating position, preferably, the air passage body 30 is provided with an exhaust cavity, the front of which is connected to the water bottle joint and the rear end of which is provided with an exhaust channel and an exhaust hole, an exhaust valve 80 is provided in the exhaust cavity, an exhaust rod is provided at the rear end of the exhaust valve 80 along the exhaust hole and extends outside the air passage body 30, an exhaust push rod support 81 is provided at the rear end of the exhaust rod in the main unit 10, a pressure surface 811 is provided on the surface of the exhaust push rod support 81, and an inclined guide surface 812 is provided at the lower end of the pressure surface 811, and the exhaust rod is normally in contact with the pressure surface 811, causing the exhaust valve 80 to seal the exhaust channel.

[0032] When the air passage body 30 swings outward relative to the sub-unit 20 to be mounted, the exhaust rod swings downward along the positive pressure surface 811 until it cannot abut against the exhaust push rod support 81, at which time the exhaust valve 80 can move freely into the exhaust cavity, thereby connecting the aerated water bottle to the outside, and the aerated water bottle cannot store gas. When the air passage body 30 moves the aerated water bottle to swing and reset, the exhaust rod moves along the inclined guide surface 812 to the positive pressure surface 811, so that the exhaust valve 80 seals the exhaust channel, allowing carbon dioxide and other gases to fill the aerated water bottle and enter a high-pressure state. Preferably, the exhaust valve 80 comprises a front end body and a rear end body, the exhaust rod is installed in the rear end body, and a tension elastic member is installed between the front end body and the rear end body. Under normal conditions, the front end body seals the exhaust channel due to the action of the tension elastic member and the positive pressure surface 811. When the air pressure in the bubble bottle is too high, the excessive air pressure will push the front end body toward the rear end body to open the exhaust channel, thereby further relieving the pressure.

[0033] Preferably, a weight sensor 71 is installed below the intake body 40, an intake body support 70 is pivotally mounted within the parent unit 10, and a support part 701 is installed at the rear end of the intake body support 70, positioned below the intake body 40, for supporting or lowering the intake body 40 from the weight sensor 71. A drive lever 702 is installed at the front end of the intake body support 70, and the drive lever 702 is movably connected to the air passage body 30 so as to move and swing the drive lever 702 when the air passage body 30 swings. In this state, the intake body support 70 is moved and swings during the swinging process of the air passage body 30, and when the air passage body 30 is in the operating position, the intake body support 70 supports the intake body 40 from the weight sensor 71, so that the intake body 40 and the weight sensor 71 do not come into contact with each other and the force applied by the user to the intake presser bar 50 is not transmitted to the weight sensor 71. When the air passage body 30 swings to the position where the aerated water bottle is attached or detached from the sub-unit 20, the air passage body 30 moves the air intake body support 70 to swing, and as the support part 701 swings, the air intake body 40 is placed on the weight sensor 71, thereby measuring the real-time weight of the carbon dioxide bottle and knowing the remaining amount of gas in the carbon dioxide bottle, which is convenient for the user to prepare for replacing the gas bottle in a timely manner. Preferably, the driving lever 702 has an elongated groove, and the air intake body 40 has an interlocking pin inserted into the elongated groove, which makes it convenient for the air intake body 40 to move the driving lever 702 to swing.

[0034] In this proposal, preferably, the first reset device 36, the second reset device 55, the third reset device, the fourth reset device and the tension elastic member are all springs, but may also be other elastic structures such as elastic rubber columns, two sets of repulsive magnets, etc.

[0035] The above is merely a preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformations made using the contents of the specification and drawings of the present utility model under the concept of the present utility model, or those directly or indirectly applied to other related technical fields, are all included in the patent protection scope of the present utility model.
