Description

Technical Field

[0001] The utility model relates to the field of tea drinking machines, and more specifically, to a pipeline cleaning system of a tea drinking machine. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] With the accelerated pace of modern life, tea machines, as a convenient and efficient beverage preparation device, have been widely used in many fields such as catering, office and home. However, long-term use will cause pollutants to accumulate in the internal pipes, affecting the quality of the beverage. In the existing technology, the internal pipes of the tea machine are usually connected to the external liquid inlet pipe separately, and a solenoid valve is set on the liquid inlet pipe to control the on and off of the pipe. The cleaning liquid enters the internal pipe through the liquid inlet pipe for cleaning. However, when there is pressure in the pipe, the liquid in the pipe will break the solenoid valve and flow out in the opposite direction, causing the liquid to mix and affect the cleaning effect.

[0004] It should be noted that the above technical background is merely for the purpose of providing a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention.

[0006] In order to solve the above technical problems, the utility model provides a pipeline cleaning system for a tea drinking machine, wherein the cleaning system includes multiple liquid inlet pipelines, solenoid valves and check valves installed on the liquid inlet pipelines, the liquid inlet pipelines are connected to the internal pipelines of the tea drinking machine, and are used to transport cleaning liquid to the internal pipelines, the solenoid valves are used to control the on-off of the liquid inlet pipelines, and the check valves are installed at the downstream position of the solenoid valves, and the check valves are used to control the cleaning liquid in the liquid inlet pipelines to flow only along the liquid inlet direction.

[0007] Preferably, the check valve is a one-way valve, and the direction of the one-way valve is consistent with the inlet direction of the cleaning fluid.

[0008] Preferably, a pressure pump is further provided on the liquid inlet pipeline. The pressure pump is provided downstream of the check valve and is used to pump the cleaning liquid into the internal pipeline.

[0009] Preferably, the solenoid valve, the check valve and the pressure pump are integrated into a cleaning module, and the cleaning module includes a first interface connected to an external cleaning liquid pipeline and a second interface connected to an internal pipeline of the tea machine.
