Description

Technical Field

[0001] This application relates to the field of sparkling water machine technology, and in particular to a sparkling water machine cylinder remaining level reminder device. Background Technology

[0002] With the continuous development of technology, devices for making soft drinks (often called sparkling water machines) have been widely used, allowing people to make their own soft drinks at home for convenient consumption, improving people's living standards and meeting their requirements for healthy eating.

[0003] However, when a sparkling water machine is in use, the gas cylinder, as an important carrier for supplying gas, discharges the gas inside under high pressure. When the gas level in the cylinder is low, users often cannot tell, and they do not know after use whether there is enough gas left in the cylinder to discharge, thus wasting time. If a mechanical pressure gauge is installed, users need to actively observe it, which is easy to overlook and requires additional costs. Moreover, users do not need to constantly monitor the gas level during use; they only need to receive a reminder when the gas level in the cylinder is low. Therefore, how to solve the above problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a gas cylinder remaining level reminder device for a sparkling water machine to solve one of the above-mentioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a gas cylinder remaining level reminder device for a sparkling water machine, including: a water bottle, a body, an air inlet pipe, an exhaust pipe, and a gas cylinder. The gas cylinder delivers gas into the water bottle through the air inlet pipe and discharges excess gas from the water bottle through the exhaust pipe. A pressure detection device is installed in the body, including a pressure contact and a micro switch. The pressure contact is connected to the exhaust pipe. When the water bottle is full of gas, the pressure will be discharged from the water bottle and pass through the pressure contact. The pressure contact can mechanically actuate the micro switch after being subjected to gas pressure. A control module is installed below the micro switch. If the pressure contact does not trigger the micro switch within a preset time after the gas cylinder delivers gas into the water bottle, the control module sends a signal. A feedback device is electrically connected to the control module and is used to receive the signal sent by the control module and provide sound or visual feedback.

[0007] In some embodiments, the pressure contact includes a housing, a piston, a contact pin, and a spring, a pressure chamber is formed within the housing, and the piston is slidably disposed within the housing and can be pushed by gas passing through the exhaust pipe.

[0008] In some embodiments, the contact pin is fixedly disposed on one side of the piston being pushed and can be pushed by air pressure to cooperate with the micro switch.

[0009] In some embodiments, the spring is disposed on one side of the piston where the contact pin is located and abuts against the piston and the housing, for driving the piston to reset.

[0010] In some embodiments, a pressure relief device is also included, wherein the exhaust pipe is connected to both the pressure contact and the pressure relief device via a tee.

[0011] In some embodiments, the feedback device may be a display screen or a buzzer or a combination of both.

[0012] The beneficial effects of this application are as follows: when the gas pressure inside the water bottle is full, the gas will be discharged from the exhaust pipe and pass through the pressure contact. When the pressure contact is under pressure, it will drive the micro switch. When the gas bottle is full, the feedback device will not be triggered. When the gas pressure inside the gas bottle is insufficient to enter the exhaust pipe or drive the pressure contact, that is, when the pressure contact does not trigger the micro switch within the preset time of gas release from the gas bottle, the feedback device will be triggered to remind the user to replace the gas bottle or refill it. At the same time, it can also prevent gas leakage from the gas bottle due to the water bottle not being sealed. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0019] In the embodiments of this application, please refer to Figure 1-3 As shown, this application provides a gas cylinder 5 remaining level reminder device for a sparkling water machine, mainly including: a water bottle 1, a body 2, an air inlet pipe 3, an exhaust pipe 4, and a gas cylinder 5. The gas cylinder 5 delivers gas into the water bottle 1 through the air inlet pipe 3 and discharges excess gas from the water bottle 1 through the exhaust pipe 4. A pressure detection device 6 is installed inside the body 2, including a pressure contact 61 and a micro switch 62. The pressure contact 61 is connected to the exhaust pipe 4. When the water bottle 1 is full of gas pressure, the gas pressure will be discharged from the water bottle 1 and pass through the pressure contact 61. The pressure contact 61 can mechanically actuate the micro switch 62 after being subjected to gas pressure. A control module 7 is installed below the micro switch 62. If the pressure contact 61 does not trigger the micro switch 62 within a preset time after the gas cylinder 5 delivers gas into the water bottle 1, the control module 7 sends a signal. A feedback device 8 is electrically connected to the control module 7 and is used to receive the signal sent by the control module 7 and provide sound or visual feedback.

[0020] When the gas cylinder 5 is full, the high gas pressure allows the gas to quickly enter the water bottle 1 from the inlet pipe 3 for dissolution. Some of the excess gas will enter the exhaust pipe 4 and be discharged or recycled. When the gas moves in the exhaust pipe 4, it will pass through the pressure contact 61 and form pressure. The pressure contact 61 converts the gas pressure into mechanical energy and drives the micro switch 62. The micro switch 62 sends a signal, which is received by the control module 7. The control module 7 is programmed to receive the signal from the micro switch 62 within a preset time after the gas cylinder 5 releases gas. Otherwise, it will send a signal to the feedback device 8 to inform the user that the gas level in the gas cylinder 5 is low, so that the user can refill or replace it in advance.

[0021] As one embodiment, after the micro switch 62 is triggered, the control module 7 can also provide the feedback device 8 with a signal that the gas cylinder 5 is being filled normally, thus optimizing the user experience.

[0022] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0023] Specifically, the pressure contact 61 includes a housing 611, a piston 612, a contact pin 613, and a spring 614. A pressure chamber is formed within the housing 611, and the piston 612 is slidably disposed within the housing 611 and can be pushed by gas passing through the exhaust pipe 4. The contact pin 613 is fixedly disposed on one side of the direction in which the piston 612 is pushed and can be pushed by air pressure to cooperate with the micro switch 62. The spring 614 is disposed on the side of the piston 612 where the contact pin 613 is disposed and abuts against the piston 612 and the housing 611, and is used to drive the piston 612 to reset. With this configuration, under the action of air pressure, the piston 612 can overcome the driving force of the spring 614 and drive the contact pin 613 to control the micro switch 62. In this embodiment, in order to facilitate the installation of the housing 611 with the spring 614, the contact pin 613 and the piston 612, an abutment block 615 is also provided at one end of the housing 611 to abut against one side of the spring 614 and limit the range of motion of the piston 612 and the contact pin 613.

[0024] Preferably, a pressure relief device 9 is also included. The exhaust pipe 4 is connected to the pressure contact 61 and the pressure relief device 9 through a three-way fitting 41. With this configuration, excess gas can be relieved while passing through the pressure contact 61 and being driven.

[0025] Reference Figure 1 As shown, the feedback device 8 can be any one of a display screen, a buzzer, or a combination of both. In this embodiment, a display screen and a built-in buzzer are used to provide feedback to the user, so that the user can replace or inflate the air in advance.
