[0023] Method of using the above-mentioned sparkling water machine: including installation method, judgment method and calculation of carbon dioxide residual amount;

[0024] The installation method is as follows: install the carbon dioxide gas cylinder on the gas cylinder joint, swing the machine head upward, install the bubble water bottle into the connection port of the machine head, reset the machine head downward, press the air inlet button to enter the automatic gas filling mode, inject carbon dioxide gas into the bubble water bottle to prepare the bubble water machine, and switch to the manual gas filling mode when the automatic gas filling mode cannot be entered;

[0025] Automatic gas filling mode: the electronic control drive drives the gas filling button to move to the working position, and the gas inlet button is pressed to drive the gas filling pressure rod to press down. The electronic control drive drives the gas filling button to fix the gas inlet pressure rod through the buckle hole and the buckle hook, so as to automatically press down the gas inlet rod continuously. When the pressing time reaches the specified time or the pressure value in the pressure water bottle assembly is reached, the electronic control drive drives the gas filling button to swing and reset, and releases the gas inlet pressure rod to reset it.

[0026] Manual filling mode: The filling button is in the initial position, and the air intake button is pressed continuously, so that the air intake pressure rod is pressed down manually;

[0027] The judgment method is as follows:

[0028] Determine whether the bubble water machine is connected to a power source. If the bubble water machine is not connected to a power source, the electronic control drive is not powered and cannot enter the automatic gas filling mode;

[0029] The tilting ball switch is used to determine the tilting angle of the bubble water machine. If the tilting angle of the bubble water machine exceeds the specified value, the automatic gas filling mode cannot be entered or the automatic gas filling mode is stopped;

[0030] Determine whether the pressure water bottle assembly is installed. If the pressure water bottle assembly is not installed on the machine head, the water bottle detection switch cannot detect the pressure water bottle assembly, and the sparkling water machine cannot enter the automatic gas filling mode;

[0031] Determine whether the machine head is reset. If the machine head swings downward and does not reset to the specified position, the machine head detection switch does not detect the machine head, and the bubble water machine cannot enter the automatic gas filling mode;

[0032] In the automatic gas filling mode, if the pressure sensor cannot detect the pressure rise, it is determined that the bottle body of the pressure water bottle assembly is not installed, and the automatic gas filling mode stops;

[0033] In the automatic refueling mode, if the pressure sensor detects that the pressure rises slowly, it determines that the gas volume of the carbon dioxide cylinder is insufficient and prompts through the reminder device;

[0034] In the automatic gas filling mode, if the pressure sensor detects that the pressure rises to a certain value but still cannot reach the specified pressure, it is judged that there is a gas leakage fault and a reminder is given through the reminder device;

[0035] Calculation of carbon dioxide residual amount: When the machine head swings upward, it drives the support part to swing, so that the push end approaches the air intake body. The air intake body drives the carbon dioxide cylinder to press on the weight sensor, thereby weighing the weight of the carbon dioxide cylinder and subtracting the weight of the carbon dioxide cylinder and the weight of the air intake assembly, so as to calculate the remaining carbon dioxide and prompt it through the reminder device.

[0036] As a further improvement of the above technical solution, in the automatic gas filling mode, the longest gas filling time is 12 seconds.

[0037] As a further improvement of the above technical solution, during the calculation process of the carbon dioxide remaining amount, when the weight of the carbon dioxide cylinder is greater than 1635 grams, it is judged as a large cylinder, and the total weight of the carbon dioxide gas is 880 grams. When the weight of the carbon dioxide cylinder is between 780 grams and 1635 grams, it is judged as a small cylinder, and the total weight of the carbon dioxide gas is 380 grams. When the remaining gas volume in the carbon dioxide cylinder is lower than the set percentage, the reminder device will give a strong prompt.

[0038] The beneficial effects of the present invention are as follows: the operation of the present scheme is safer, and if the operation of the sparkling water machine is not standardized, the machine cannot be automatically gassed, and can only be manually gassed when the user specifically intends, which is safer. At the same time, the amount of remaining carbon dioxide gas can be measured in real time according to the weight of the carbon dioxide cylinder, so that the user can prepare spare carbon dioxide cylinders immediately, which is more convenient.

[0063] The electric control drive 60 is arranged in the main unit 10 and is located below the air inlet pressure rod 50. The output end of the electric control drive 60 is connected to the gas filling button rod 61. The middle part of the gas filling button rod 61 is pivotally connected to the main unit 10. The top of the gas filling button rod 61 is provided with a hook 611 or a button hole 55 that matches the button hole 55 or the hook 611. The hook 611 can be swingably buckled in the button hole 55.

[0066] A tilt ball switch 92, wherein the tilt ball switch 92 is disposed in the main unit 10 or in the head 11;

[0067] The water bottle detection switch is arranged at the bottom of the head 11 and is used for abutting detection with the pressure water bottle assembly 80.

[0068] At the same time, this solution also discloses the use method of this product, including installation method, judgment method and carbon dioxide residual calculation;

[0069] The installation method is as follows: install the carbon dioxide gas cylinder 14 on the gas cylinder joint, swing the machine head 11 upward, install the bubble water bottle into the connection port of the machine head 11, reset the machine head 11 downward, press the air intake button 57 to enter the automatic gas filling mode, inject carbon dioxide gas into the bubble water bottle to prepare the bubble water machine, and switch to the manual gas filling mode when the automatic gas filling mode cannot be entered. During the upward swing of the machine head 11, the support member 40 is driven to swing, so that the push end approaches the air intake body 30, and the air intake body 30 drives the carbon dioxide gas cylinder 14 to press on the weight sensor 44, thereby weighing the weight of the carbon dioxide gas cylinder 14, and subtracting the self-weight of the carbon dioxide gas cylinder 14 and the weight of the air intake assembly, so as to calculate the remaining amount of carbon dioxide and prompt it through the reminder device;

[0070] The automatic gas filling mode is: the electric control drive 60 drives the gas filling button 61 to move to the working position, at this time, the button hole 55 and the hook 611 overlap to a certain extent in the horizontal direction, and the gas filling button 57 is pressed to drive the gas filling pressure rod 50 to press down, so that the gas filling button 61 overcomes the force brought by the electric control drive 60 under the action of the gas filling pressure rod 50 and swings, so that the gas filling button 61 continues to be pressed down, until the hook 611 overlaps with the button hole 55, the gas filling button 61 continues to swing under the action of the electric control drive 60 so that the hook 611 The air intake pressure rod 50 is fixed by snapping into the buckle hole 55, so that the air intake rod 31 is automatically pressed down continuously. When the pressing time reaches the specified time or the pressure value in the pressure water bottle assembly 80 is reached, the electric control drive 60 drives the air filling buckle rod 61 to swing and reset, and the air intake pressure rod 50 is released to reset the air intake pressure rod 50. The pressure value can be adjusted manually, so that different concentrations of bubble water machines can be prepared. At the same time, the specified pressurization time can prevent explosion caused by excessive gas filling. Preferably, in the automatic gas filling mode, the longest gas filling time is 12 seconds;

[0071] Manual gas filling mode: the gas filling button 61 is at the initial position, and the gas filling button 57 is continuously pressed, so that the gas filling pressure rod 50 continuously presses the gas filling rod 31 manually;

[0072] The following judgments will be made when entering the automatic gas filling mode and in the automatic gas filling mode:

[0073] 1. Determine whether the bubble water machine is connected to a power source. If the bubble water machine is not connected to a power source, the electronic control drive 60 is not powered and cannot enter the automatic gas filling mode;

[0074] 2. The tilt angle of the bubble water machine is determined by tilting the ball switch 92. If the bubble water machine tilts more than a specified value, the automatic gas filling mode cannot be entered or the automatic gas filling mode is stopped. In normal use, it is generally defined that the bubble water machine will tip over if the tilt angle exceeds 15 degrees;

[0075] 3. Determine whether the pressure water bottle assembly 80 is installed. If the pressure water bottle assembly 80 is not installed on the machine head 11, the water bottle detection switch cannot detect the pressure water bottle assembly 80, and the bubble water machine cannot enter the automatic gas filling mode;

[0076] 4. Determine whether the handpiece 11 is reset. If the handpiece 11 swings downward and does not reset to the specified position, the handpiece detection switch does not detect the handpiece 11, and the bubble water machine cannot enter the automatic gas filling mode;

[0077] 5. In the automatic gas filling mode, if the pressure sensor 73 cannot detect the pressure rise, it is determined that the bottle body 82 of the pressure water bottle assembly 80 is not installed, and the automatic gas filling mode is stopped;

[0078] 6. In the automatic gas filling mode, if the pressure sensor 73 detects that the pressure rises slowly, it is determined that the gas volume of the carbon dioxide cylinder 14 is insufficient and a reminder is given through the reminder device;

[0079] 7. In the automatic gas filling mode, if the pressure sensor 73 detects that the pressure rises to a certain value but still cannot reach the specified pressure, it is determined that there is a gas leakage fault and a prompt is given through the reminder device.

[0080] Compared with the prior art, the present solution is safer to operate. If the bubble water machine is not operated properly, the automatic gas filling mode cannot be entered and only the manual gas filling mode can be performed. The manual gas filling mode requires the user to perform it intentionally. Therefore, at this time, the user's attention will be focused on the use of the bubble water machine, which is less likely to cause danger and is safer. At the same time, the amount of remaining carbon dioxide gas can be measured in real time according to the weight of the carbon dioxide cylinder 14, so that the user can prepare a spare carbon dioxide cylinder 14 in time, which is more convenient.

[0081] Since there are more than 14 specifications of carbon dioxide gas cylinders, during the weighing process, the user can manually input the specifications of the gas cylinder. In order to optimize the operation flow, it is preferred that when weighing the carbon dioxide gas cylinder 14, the sparkling water machine can automatically identify the size of the gas cylinder according to the weighed weight, such as the empty weight of the 0.6L carbon dioxide gas cylinder 14 is 780 grams, the gas weight is 380 grams, and the total weight is 1160 grams. The empty weight of the 1.34L carbon dioxide gas cylinder 14 is 1635 grams, the gas weight is 880 grams, and the total weight is 2515 grams. When the total weight exceeds the empty weight of the 1.34L carbon dioxide gas cylinder 14, the system will judge it as a large gas cylinder, otherwise it is a small gas cylinder. After identifying the size of the gas cylinder, the system subtracts the weight of the carbon dioxide gas cylinder 14 and the weight of the air intake body, and the remaining weight is the weight of the carbon dioxide gas. Preferably, when the remaining gas volume of the carbon dioxide gas cylinder 14 is lower than the set percentage, the reminder device will give a strong prompt.

[0087] In one embodiment, the active connection between the active end 111 and the driven end 42 is performed by pivoting a telescopic rod on the active end 111, and the other end of the telescopic rod is pivoted to the driven end 42, thereby forming a crank connecting rod 53 structure for driving.
