[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] As shown Figures 1 to 6 in the figure, in this embodiment, a sparkling water maker is provided, which includes a machine body 1, a gas cylinder 2, a gas valve 3, a pressing structure 4, a linear driver 5, a switch structure 6 and a control structure 7. A bottle mouth fixing structure 11 is arranged inside the machine body 1; the gas cylinder 2 is connected to the bottom of the bottle mouth fixing structure 11; the gas valve 3 is arranged at the bottle mouth of the gas cylinder 2 and is adapted to inflate the water bottle 8; the pressing structure 4 is movably connected to the bottle mouth fixing structure 11 and is adapted to control the opening and closing of the gas valve 3; the linear driver 5 is connected to the bottle mouth fixing structure 11, and the output end is connected to the pressing structure 4 and is adapted to drive the pressing structure 4 to move; the switch structure 6 is arranged outside the machine body 1; the control structure 7 is communicatively connected to the linear driver 5 and the switch structure 6 respectively.

[0033] The air injection process of the sparkling water maker in this embodiment includes: the control structure 7 receives the air injection signal of the switch structure 6, controls the movement of the output end of the linear driver 5, the output end drives the pressing structure 4 to move upward and opens the gas valve 3, and the gas in the gas cylinder 2 passes through the gas valve 3 into the water bottle 8 to make sparkling water. There is no need for manual pressing and air injection, the degree of automation is higher, and the air injection process is more convenient, fast and labor-saving. After the air injection process of the sparkling water maker of the present invention ends, the output end of the linear driver 5 returns to its original position, the output end drives the pressing structure 4 to move upward, and the gas valve 3 closes. And the control structure 7 can set the air injection time as needed, so that the gas valve 3 remains open for a corresponding time under the control of the pressing structure 4 and the linear driver 5 to complete the production of sparkling water. The communication connection in this embodiment includes connection through wires and connection through networks such as 2G, 3G, 4G, 5G or WIFI.

[0034] The stroke of the motor cam assembly in the prior art is small. The stroke required by the pressing structure 4 is generally greater than 20 mm. To meet the stroke of the pressing structure 4, the size of the cam of the motor cam assembly needs to be increased, occupying more space, resulting in a corresponding increase in the overall size of the sparkling water maker. In the sparkling water maker of this embodiment, the driving structure is a linear driver 5, which can realize linear driving of the pressing structure 4, has a large stroke, a small volume, occupies less space, and the overall volume of the sparkling water maker is reduced, meeting the development trend of miniaturization of household appliances.

[0035] The motor cam assembly in the prior art belongs to a higher pair mechanism, with relatively large contact stress and easy to wear. When the wear is serious, it will reduce the working stroke of the pressing structure 4, resulting in insufficient air volume during inflation, so that the dissolved carbon dioxide gas in the produced sparkling water is insufficient, affecting the taste of the sparkling water. Compared with the motor cam assembly that is easy to wear and affects the stroke when severely worn, the linear actuator 5 in this embodiment is reliably connected, not easy to wear, and even if wear occurs, it will not affect the stroke, ensuring the inflation effect. The load that the motor cam assembly in the prior art can bear is small, and the force required for the pressing structure 4 is generally between 20 N and 100 N, and the motor cam assembly may not be able to press down the lever. The linear actuator 5 of the present invention can bear a large load, ensuring the load required for the pressing structure 4 and achieving a good driving effect.

[0036] As Figure 2 and Figure 4 shown, in the sparkling water machine of this embodiment, the linear actuator 5 includes a sleeve 51, a driving motor, and a push rod 52. The sleeve 51 is connected to the bottle mouth fixing structure 11; the driving motor is arranged in the sleeve 51; one end of the push rod 52 is arranged in the sleeve 51 and connected to the output shaft of the driving motor, and the other end is an output end connected to the pressing structure 4, and the output end is telescopically arranged outside the sleeve 51. The sleeve 51 plays a role in protecting the driving motor and also plays a role in limiting the movement of the push rod 52, preventing the push rod 52 from moving and offsetting, and affecting the driving effect of the linear actuator 5 on the pressing structure 4.

[0037] As an alternative embodiment, it can also be that the linear actuator 5 only includes a driving motor and a push rod 52, without including the sleeve 51. The driving motor is connected to the bottle mouth fixing structure 11, the output shaft of the driving motor is connected to one end of the push rod 52, and the other end of the push rod 52 is connected to the pressing structure 4.

[0038] In the sparkling water machine of this embodiment, a fixing frame 111 is provided on the side of the bottle mouth fixing structure 11 facing away from the gas cylinder 2, and the sleeve 51 is connected to the end of the fixing frame 111 away from the bottle mouth fixing structure 11. Fixing the sleeve 51, only the push rod 52 moves, preventing problems such as movement interference. And the pressing structure 4 has two movements of moving downward and upward relative to the bottle mouth fixing structure 11. The sleeve 51 is connected to the end of the fixing frame 111 away from the bottle mouth fixing structure 11, providing space for the movement of the push rod 52 and preventing the push rod 52 from having movement interference.

[0039] In a specific implementation manner, the sleeve 51 is hinged to one end of the fixing frame 111 away from the bottle mouth fixing structure 11. The fixing frame 111 is a groove-shaped structure protruding from the bottle mouth fixing structure 11. Hinge holes are provided on two opposite groove walls of the groove-shaped structure, and one end of the sleeve 51 is hinged between the two groove walls through a hinge shaft.

[0040] In the bubble water machine of this embodiment, a support frame 112 is provided on the side of the bottle mouth fixing structure 11 facing away from the gas cylinder 2. A support groove 113 is provided on the side of the support frame 112 away from the bottle mouth fixing structure 11. One end of the sleeve 51 is hinged to the fixing frame 111, and the other end is supported in the support groove 113. The support groove 113 limits and supports the sleeve 51 to prevent the sleeve 51 from shifting and affecting the force exerted by the push rod 52 on the pressing structure 4.

[0041] As Figure 2 and Figure 4 shown, in the bubble water machine of this embodiment, the pressing structure 4 includes a pressing lever 41. A protruding hinge seat 114 is provided on the side of the bottle mouth fixing structure 11 facing away from the gas cylinder 2. The pressing lever 41 is hinged to the hinge seat 114. One end of the power arm 411 of the pressing lever 41 is hinged to the output end, and the power arm 411 is adapted to control the opening and closing of the air valve 3. The pressing lever 41 rotates relative to the hinge seat 114. When the power arm 411 moves downward, the air valve 3 is opened under the pressing of the power arm 411, and the carbon dioxide gas in the gas cylinder 2 is introduced into the water bottle 8 from the gas cylinder 2; when the power arm 411 moves upward, the air valve 3 is closed.

[0042] In a specific implementation manner, the hinge seat 114 includes two relatively spaced hinge plates. A hinge hole is provided on each of the two hinge plates. Hinge shafts protrude from both sides of the pressing lever 41, and both ends of the hinge shaft are respectively connected to a hinge hole; alternatively, a hinge hole is provided on the pressing lever 41, and the hinge shaft passes through the hinge hole on the pressing lever 41 and is respectively connected to the hinge holes on the hinge plates. The pressing lever further includes a resistance arm 412. One end of the resistance arm 412 away from the power arm 411 is linked to the pressure relief valve of the water bottle 8. When the air valve is opened, the resistance arm 412 controls the closing of the pressure relief valve. When the air valve is closed, the resistance arm 412 controls the opening of the pressure relief valve. The fulcrum of the pressing lever 41 divides the pressing lever 41 into a power arm 411 and a resistance arm 412.

[0043] In the bubble water machine of this embodiment, a tubular structure 115 protruding in the direction away from the gas cylinder 2 is provided on the bottle mouth fixing structure 11. The gas cylinder 2 is detachably connected to one end of the tubular structure 115; the pressing structure 4 further includes a transmission member 42. One end of the transmission member 42 is movably arranged in the tubular structure 115 and cooperates with the air valve 3; the other end is located outside the tubular structure 115 and cooperates with the power arm 411.

[0044] In a specific embodiment, an exhaust port is provided on the side of the tubular structure 115. The exhaust port is connected to the air inlet of the water bottle 8 of the sparkling water maker through an intake pipe. The power arm 411 controls the opening and closing of the air valve 3 through a transmission member 42. One end of the tubular structure 115 close to the bottle mouth fixing structure 11 is detachably connected to the bottle mouth joint, preferably by a threaded connection. When the pressing lever 41 is pressed down, the transmission member 42 moves downward, applying a force to the air valve 3 to open the air valve 3. The air outlet of the gas cylinder 2 is communicated with the exhaust port, and carbon dioxide gas enters the water bottle 8 through the exhaust port. The pressing structure 4 further includes a third elastic member 43. The third elastic member 43 abuts between the transmission member 42 and the bottle mouth fixing structure 11. When the pressing force on the pressing lever 41 is no longer applied, the transmission member 42 returns to its original position under the elastic force of the third elastic member 43, and the air valve 3 closes, and the air outlet of the gas cylinder 2 closes. The transmission member 42 is provided with a first limiting flange and a second limiting flange. One end of the transmission member 42 is limited within the tubular structure 115 by the first limiting flange, and the other end of the transmission member 42 is limited outside the tubular structure 115 by the second limiting flange. The sparkling water maker of this embodiment further includes a first sealing structure and a second sealing structure. The first sealing structure is clamped between the end of the tubular structure 115 and the bottle mouth joint of the gas cylinder 2; the second sealing structure includes at least one sealing ring sleeved in at least one sealing groove on the transmission member 42. The sealing ring is located between the transmission member 42 and the pipe wall of the tubular structure 115 to achieve sealing between the two.

[0045] In this embodiment, the pressing structure 4 further includes an elastic member 43. The elastic member 43 abuts between the bottle mouth fixing structure 11 and the power arm 411. When the power arm 411 no longer receives the driving force of the linear driving structure, the power arm 411 can return to its original position under the elastic force of the elastic member 43, preventing the power arm 411 from still applying a force to the air valve 3, resulting in the incorrect opening of the air valve 3 and causing waste of gas.

[0046] As Figure 5 and Figure 6 shown, in this embodiment, the switch structure 6 includes an inflation switch 61 and a child lock switch 62. The inflation switch 61 is adapted to control the linear driver 5, and the child lock switch 62 is adapted to lock or unlock the inflation switch 61. The child lock switch 62 is provided to avoid triggering the inflation action when the inflation switch 61 is accidentally touched, resulting in waste of carbon dioxide gas or causing personal injury.

[0047] Operate the air injection switch 61 to turn it on. The control structure 7 receives the air injection signal and controls the movement of the output end of the linear actuator 5 according to the air injection signal, driving the pressing structure 4 to move downward to open the air valve 3 and inject air into the water bottle 8. After the air injection lasts for a corresponding time, the control structure 7 controls the output end of the linear actuator 5 to move in the reverse direction, driving the pressing structure 4 to move upward to close the air valve 3. Operating the child lock switch 62 once can lock the air injection switch 61, and at this time, the sparkling water machine cannot perform the normal production of sparkling water. Operating the child lock switch 62 again can unlock the air injection switch 61, and the sparkling water can be produced normally. After the sparkling water machine stops being used for a corresponding time, the air injection switch 61 is automatically locked, and operating the child lock switch 62 can unlock the air injection switch 61.

[0048] For the sparkling water machine of this embodiment, both the air injection switch 61 and the child lock switch 62 are touch switches, which is convenient for operation.

[0049] For the sparkling water machine of this embodiment, the machine body 1 includes a fuselage 12 and a top cover 13. The top cover 13 is detachably connected to the fuselage 12. The bottle mouth fixing structure 11 is arranged inside the fuselage 12. The control structure 7 is connected to the bottom of the top cover 13, and the switch structure 6 is arranged on the top of the top cover 13. The top cover 13 can be a touch screen, and the air injection switch 61 and the child lock switch 62 are touch switches arranged on the touch screen. Alternatively, the air injection switch 61 and the touch switch are embedded in the top cover 13. The control structure 7 is connected to the bottom of the top cover 13 and is located below the switch structure 6, which is convenient for the arrangement of the switch structure 6.

[0050] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
