Description

Technical Field

[0001] The present invention relates to the field of sparkling water machines, and in particular to a sparkling water machine with a push-type exhaust and intake function. Background Art

[0002] A sparkling water machine is a machine for preparing sparkling water. Its functional principle is to inject carbon dioxide gas into a liquid and dissolve the carbon dioxide gas in the water by forming a high pressure in a container. During the operation of the machine, two operations of intake and exhaust need to be performed on the machine. Intake means injecting carbon dioxide gas into a sparkling water bottle, and exhaust means relieving the pressure inside the sparkling water bottle after the carbon dioxide is dissolved, so that the sparkling water bottle can be safely removed from the sparkling water machine. The existing intake and exhaust operations need to be performed through two different switches, and the structure is relatively complex. Moreover, most of the existing exhaust structures are electrically controlled, and the problem is that they are prone to failures, resulting in unsmooth exhaust. Summary of the Invention

[0003] To solve the above problems, the purpose of the present invention is to provide a sparkling water machine with a simple structure, stable operation, and capable of performing intake and exhaust operations respectively by pressing different positions of a pressing face cover.

[0004] The technical solution adopted by the present invention to solve the problem is: a push-type exhaust and intake sparkling water machine, comprising:

An exhaust retaining member is pivotally connected inside the installation cavity on one side of the air passage body and facing the exhaust hole. A normal abutting position and a reciprocating sinking groove located on one side of the normal abutting position are arranged on the surface of the exhaust retaining member. The end of the valve rod abuts on the normal abutting position and can move relative to the exhaust retaining member. A driving pressure groove is obliquely arranged on the exhaust retaining member. The tail end of the driving rod is inserted into the driving pressure groove and is used to drive the exhaust retaining member to swing. The reciprocating sinking groove includes a first slideway and a second slideway located at the end of the first slideway and communicating with the first slideway. The front end of the first slideway is lower than the surface of the exhaust retaining member to form a first check surface. The end of the first slideway is higher than the starting end of the second slideway to form a second check surface. The end of the second slideway is smoothly guided to the normal abutting position. A first reset member is arranged on the exhaust retaining member.

[0011] As a further improvement of the above technical solution, an elastic member is arranged between the valve body and the sealing plug. The elastic member gives the sealing plug a force towards the valve hole direction.

[0012] As a further improvement of the above technical solution, the front end of the sealing plug is conical.

[0013] As a further improvement of the above technical solution, a second reset member is arranged at the bottom of the rear end of the driving rod.

The middle part of the air inlet pressing rod is located above the air inlet rod. The front end of the air inlet pressing rod is located below the pressing cover.

[0015] As a further improvement of the above technical solution, the front ends of the intake pressure rod and the driving rod are both located at the bottom of the front end of the pressing face cover, and a lifting rod is arranged on the connecting frame below the driving rod.

[0016] As a further improvement of the above technical solution, a limit bracket for restricting the downward movement distance of the rear end of the pressing face cover is arranged at the bottom of the rear end of the pressing face cover. A reset push rod that can abut against the bottom surface of the pressing face cover is arranged at the upper end of the limit bracket. A reset spring for driving the reset push rod to move upward is arranged at the bottom of the reset push rod. When the pressing face cover is in a horizontal state, the reset push rod is in a balanced state.

[0017] As a further improvement of the above technical solution, a circular extension plate extending towards the middle is arranged at the top edge of the installation cavity, and a circular limit plate extending towards the outside is arranged at the edge of the pressing face cover. The circular limit plate is located below the circular extension plate and can abut against the bottom surface of the circular extension plate.

[0018] The beneficial effects of the present invention are as follows: By pressing the front and rear ends of the pressing face cover, the driving rod and the intake pressure rod can be driven to move respectively, so as to open the exhaust valve or press the intake rod respectively, thereby completing the exhaust or intake work. The structure is simple and the operation is convenient. Description of the Drawings

[0033] Referring to Figures 1 to 10 , a bubble water machine with a push-button exhaust and intake, includes:

[0034] A main unit 10, on which there is a water bottle placement position 11 and a bottle mouth connector 12 located on the water bottle placement position 11. There is an air nozzle 13 on the bottle mouth connector 12. An installation cavity is provided inside the main unit 10. A main body installation bracket 20 is provided in the installation cavity. An air intake assembly 30 is provided on the main body installation bracket 20. The air intake assembly 30 includes an air intake channel 32 and an air intake rod 31 located inside the air intake channel 32. A connection port for connecting a gas cylinder is provided at the bottom of the air intake channel 32. A gas path main body 40 is provided on the main body installation bracket 20. The gas path main body 40 includes a main gas path channel 41 communicating with the air intake channel 32 and an exhaust channel 42 extending from the lower end of the gas path main body 40. The air nozzle 13 is installed on the gas path main body 40 and communicates with the main gas path channel 41. An exhaust valve for opening and closing the exhaust channel 42 is provided in the exhaust channel 42;

[0035] A driving rod 70, the driving rod 70 is provided on the main body installation bracket 20, and the driving rod 70 is connected to the exhaust valve for driving the exhaust valve to move on the exhaust channel 42 so as to open and close the exhaust channel 42;

[0036] An air intake pressure rod 60, the air intake pressure rod 60 is provided in the installation cavity, the air intake pressure rod 60 is located above the air intake rod 31 and is used for driving the air intake rod 31 to press down;

[0037] A pressing face cover 50, the middle part of the pressing face cover 50 is pivotally connected to the installation cavity, the pressing face cover 50 swings up and down relative to the installation cavity under the action of an external force. The driving rod 70 and the air intake pressure rod 60 are located at the lower end of the pressing face cover 50. When pressing down the two sides of the pressing face cover 50, the driving rod 70 and the air intake pressure rod 60 can be driven to move respectively.

[0038] By pressing the front and rear ends of the pressing face cover 50, the driving rod 70 and the air intake pressure rod 60 can be driven to move respectively, so as to open the exhaust valve or press the air intake rod 31 respectively, thereby completing the exhaust or air intake work. The structure is simple and the operation is convenient.

[0039] For further optimization, preferably, the middle part of the driving rod 70 is pivotally connected to the installation cavity so as to be able to swing up and down relative to the installation cavity. The front end of the driving rod 70 is fixed to the bottom of the front end of the pressing face cover 50 through a connecting frame 51. The tail end of the driving rod 70 is connected to the exhaust valve. When exhaust is needed, press the rear end of the pressing face cover 50, so that the front end of the pressing face cover 50 can be lifted upwards, which can drive the front end of the driving rod 70 to swing upwards and the rear end of the driving rod 70 to press down, thereby driving the exhaust valve to move. Or in another embodiment, directly press the front end of the pressing face cover 50 to drive the front end of the driving rod 70 to press down and the rear end of the driving rod 70 to lift up.

[0040] For further optimization, it is preferred that the exhaust passage 42 includes a valve hole 421 at the front end and a valve cavity 422 at the rear end. The valve hole 421 extends to the lower end of the gas path main body 40, and the end of the valve hole 421 is located on the front end face of the valve cavity 422. An exhaust hole 423 communicating with the outside of the gas path main body 40 is provided on the rear end face of the valve cavity 422. The exhaust valve is arranged in the valve cavity 422. The exhaust valve includes a valve body 90 and a sealing plug 91 arranged at the front end of the valve body 90 for sealing the valve hole 421. A valve stem 92 is arranged at the rear end of the valve body 90 and passes through the exhaust hole 423 and extends to the outside of the gas path main body 40. An exhaust retaining member 80 is pivotally connected in the installation cavity, located on one side of the gas path main body 40 and facing the exhaust hole 423. A normal contact position 82 and a reciprocating sinking groove 83 located on one side of the normal contact position 82 and smoothly transitioning with the normal contact position 82 are provided on the surface of the exhaust retaining member 80. A low position is provided in the reciprocating sinking groove 83. When the valve stem 92 is at the low position, the sealing plug 91 can actively or under the action of air pressure open the valve hole 421. The valve stem 92 can move relative to the exhaust retaining member 80 to enter the reciprocating sinking groove 83 to open the valve hole 421 with the sealing plug 91 of the exhaust valve head. The end of the valve stem 92 abuts against the normal contact position 82 and can move relative to the exhaust retaining member 80. A driving pressure groove 81 is inclinedly arranged on the exhaust retaining member 80. The tail end of the driving rod 70 is inserted into the driving pressure groove 81 and is used to drive the exhaust retaining member 80 to swing. It is preferred that the reciprocating sinking groove 83 includes a first slideway 831 and a second slideway 832 located at the end of the first slideway 831 and communicating with the first slideway 831. The end of the first slideway 831 is higher than the starting end of the second slideway 832 to form a check surface. The end of the second slideway 832 is smoothly guided to the normal contact position 82. A first reset member 84 is arranged on the exhaust retaining member 80.The valve stem 92 abuts against the normal abutment position 82 in the normal state. At this time, the valve stem 92 presses against the valve body 90, thereby synchronously pressing the sealing plug 91 to block the valve hole 421. At this time, air cannot be exhausted, and the machine can normally pressurize and intake air. When exhausting, press the rear end of the pressing face cover 50, so that the front end of the pressing face cover 50 tilts upward, which can drive the front end of the driving rod 70 to swing upward and the rear end of the driving rod 70 to press down. Since the rear end of the driving rod 70 is inserted into the driving groove 81 and the exhaust retaining member 80 is pivotally connected in the installation cavity, the pressing force of the driving rod 70 pressing down will drive the exhaust retaining member 80 to swing in the vertical direction, so that the exhaust retaining member 80 moves relative to the valve stem 92, causing the valve stem 92 to fall into the first slideway 831. At this time, since the valve stem 92 can no longer directly press the sealing plug 91, the air pressure in the bubble water bottle is transmitted to the valve cavity 422 through the valve hole 421, thereby pushing the sealing plug 91 and pressing the valve stem 92 tightly in the first slideway 831 to open the valve cavity 422, so that the high-pressure carbon dioxide in the bubble water bottle is discharged through the exhaust hole 423. When the exhaust is completed, release the pressing face cover 50, so that the driving rod 70 can move freely. At this time, the first reset member 84 drives the exhaust retaining member 80 to reset, and at the same time can drive the driving rod 70 to reset. During the reset process, the valve stem 92 slides along the first slideway 831 into the second slideway 832, and then moves along the second slideway 832 towards the normal abutment position 82. Through the action of the first check surface and the second check surface, the valve stem 92 is prevented from returning along the first slideway 831, thereby ensuring the exhaust effect and confirming the working state. When the pressing face cover 50 is pressed to move the driving rod 70 and the valve stem 92 falls into the first slideway 831, the exhaust work starts. Then, only when the pressing face cover 50 is pressed to the end, the valve stem 92 can be reset, which also plays a role in reminding the operator.

[0041] In other embodiments, the reciprocating groove 83 is a V-shaped arc groove. The middle of the arc groove is the low point, and both ends of the arc groove are smoothly transitioned with the normal abutment position 82.

[0042] Further optimization, preferably, an elastic member 93 is arranged between the valve body 90 and the sealing plug 91, and the elastic member 93 gives a force to the sealing plug 91 in the direction towards the valve hole 421. When the valve stem 92 abuts against the normal abutment position 82, the elastic member 93 firmly presses the sealing plug 91 on the valve hole 421 for sealing. When the valve stem 92 falls into the first slideway 831, due to the change in the stroke of the valve stem 92 in the valve cavity 422, the elastic force of the elastic member 93 on the sealing plug 91 decreases at this time, so that the air pressure in the bubble water bottle can push the sealing plug 91 to open the valve cavity 422.

[0043] Further optimization, preferably, the front end of the sealing plug 91 is in a conical shape, so that the valve hole 421 can be better closed.

[0044] For further optimization, it is preferred that a second reset member 71 is provided at the bottom of the rear end of the driving rod 70, so that the driving rod 70 can be reset more quickly.

[0045] For further optimization, it is preferred that the end of the air inlet pressure rod 60 is pivotally connected to the main body mounting bracket 20. The middle of the air inlet pressure rod 60 is located above the air inlet rod 31, and the front end of the air inlet pressure rod 60 is located below the pressing surface cover 50. On this basis, it is preferred that a third reset member is provided at the bottom of the air inlet pressure rod 60 to drive the air inlet pressure rod 60 to reset. By forming a lever effect through the pivotal connection of the air inlet pressure rod 60, the force applied by the user can be amplified, so that the air inlet rod 31 can be pressed down more easily. On this basis, it is preferred that the front ends of the air inlet pressure rod 60 and the driving rod 70 are both located at the bottom of the front end of the pressing surface cover 50. An upward lifting rod 52 located below the driving rod 70 is provided on the connecting frame 51. When the front end of the pressing surface cover 50 is pressed, the front end of the pressing surface cover 50 presses down the air inlet pressure rod 60, thereby pressing down the air inlet rod 31, so that the carbon dioxide in the carbon dioxide gas cylinder is ejected along the main gas path channel 41. At this time, the pressing surface cover 50 does not contact the driving rod 70. When the rear end of the pressing surface cover 50 is pressed, the front end of the pressing surface cover 50 drives the connecting frame 51 to move upward, and then the upward lifting rod 52 drives the front end of the driving rod 70 to swing upward. At this time, the pressing surface cover 50 does not contact the air inlet pressure rod 60.

[0046] For further optimization, it is preferred that a limit bracket 100 for restricting the downward movement distance of the rear end of the pressing surface cover 50 is provided at the bottom of the rear end of the pressing surface cover 50. A reset push rod 1001 that can abut against the bottom surface of the pressing surface cover 50 is provided at the upper end of the limit bracket 100. A reset spring for driving the reset push rod 1001 to move upward is provided at the bottom of the reset push rod 1001. When the pressing surface cover 50 is in a horizontal state, the reset push rod 1001 is in a balanced state, so that the pressing amplitude of the pressing panel can be restricted, and after the user releases the hand, the pressing panel remains in a balanced state under the action of the reset push rod 1001 and the front end reset of the air inlet pressure rod 60.

[0047] For further optimization, it is preferred that an annular extension plate 14 extending towards the middle is provided at the top edge of the installation cavity. An annular limit plate 53 extending towards the outside is provided at the edge of the pressing surface cover 50. The annular limit plate 53 is located below the annular extension plate 14 and can abut against the bottom surface of the annular extension plate 14, so as to further restrict the swinging amplitude of the pressing surface cover 50.

[0048] In other embodiments, the output ends of the air inlet pressure rod 60 and the driving rod 70 are respectively located at the lower ends on both sides of the pressing surface cover 50, so that the user can press the corresponding side of the pressing surface cover 50 to press down the corresponding air inlet pressure rod 60 and driving rod 70.

[0049] In other embodiments, the intake pressure lever 60 is L-shaped, so that the up-and-down swing at the front end of the intake pressure lever 60 can be converted into the front-and-back movement at the rear end of the intake pressure lever 60 under the lever action. The end of the exhaust valve of the intake pressure lever 60 is pivotally connected to the intake pressure lever 60, so that the front-and-back movement at the rear end of the intake pressure lever 60 can drive the exhaust valve to move horizontally in the exhaust passage 42, and then open and close the exhaust passage 42 for exhaust.

[0050] In other embodiments, the drive rod 70 is located at the lower end of the pressing face cover 50 without indirect connection using the connecting frame 51. The rear end of the air path main body 40 is provided with slots arranged vertically. The end of the exhaust passage 42 extends into the slots. The bottom of the drive rod 70 is provided with a pin sealing plate inserted into the slots. A sealing piece is arranged inside the pin sealing plate. A reset device for driving the pin sealing plate to move upward is arranged at the bottom of the pin sealing plate. When the pressing face cover 50 drives the drive rod 70 to move downward, the pin sealing plate moves downward to expose the exhaust passage 42 for exhaust. When the user releases the pressing panel, the pin sealing plate resets under the action of the reset device to close the exhaust passage 42.

[0051] In other embodiments, the intake pressure lever 60 is located at the bottom of the rear end of the pressing face cover 50, and at the same time, the intake rod 31 is directly below the intake pressure lever 60. That is, the intake pressure lever 60 serves as a gasket to prevent the pressing face cover 50 from directly acting on the intake rod 31. Since the pressing face cover 50 is generally made of plastic and the intake rod 31 is generally relatively thin, it is difficult to position directly and it is easy to generate a large pressure on a local part of the pressing face cover 50, resulting in the rupture of the pressing face cover 50.

[0052] The first reset member 84, the second reset member 71, and the third reset member in this solution are preferably springs. In other embodiments, elastic rubber columns and other embodiments can also be selected.

[0053] In other embodiments, the intake pressure lever 60 can indirectly drive the intake rod 31 to press down. For example, a momentary switch is arranged at the lower end of the intake pressure lever 60. The momentary switch is electrically connected to a drive motor, and the drive motor is connected to the intake rod 31. Thus, when the intake pressure lever 60 presses down to touch the momentary switch, the drive motor drives the intake rod 31 to press down.

[0054] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
