Description

Technical Field

[0001] This utility model belongs to the field of tea ceremony machine technology, specifically relating to an anti-siphon structure for a tea ceremony machine and the tea ceremony machine itself. Background Technology

[0002] Tea brewing machines, which use a pump to draw and heat water for brewing, often face a physical problem after shutdown: due to the height difference between the boiler and the outlet, when the pump stops, a water column forms in the outlet pipe due to the liquid's own weight and the principle of communicating vessels. This water column continues to fall under gravity, creating a local negative pressure behind the highest point of the pipe, i.e., a siphon effect. This effect continuously draws water out of the boiler, resulting in unnecessary water leakage even after the machine is turned off. This not only wastes water resources but can also lead to water accumulation inside the machine, causing a series of problems such as short circuits, corrosion of metal parts, and microbial growth, seriously affecting the reliability and lifespan of the equipment. Although some existing technologies attempt to solve this problem, such as adding complex one-way valves or electromagnetic venting structures, these are often difficult to apply stably and effectively in actual products due to high cost, complex structure, or insufficient reliability.

[0003] This invention aims to solve or at least alleviate the problem of siphoning in the water pipes of a tea maker after it has been shut down by providing an anti-siphon structure for the tea maker. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides an anti-siphon structure for a tea maker, which has the advantage of being able to prevent siphoning.

[0005] To achieve the above objectives, this utility model provides an anti-siphon structure for a tea maker, comprising: a water boiler, wherein a water outlet pipe is installed at the bottom of the water boiler, the water outlet pipe being divided into a water rising section, a horizontal flow section, and a water falling section from the bottom of the water boiler, a water pump being provided in the water rising section, and the water falling section being divided into an upper section and a lower section of the water outlet pipe, the upper section of the water outlet pipe being inserted into the lower section of the water outlet pipe, and a venting groove being provided in the inserted portion of the upper section of the water outlet pipe.

[0006] As an improvement of this utility model, the ventilation groove is a serrated groove axially arranged on the outer wall of the upper section of the water outlet pipe.

[0007] As an improvement of this utility model, the venting grooves are arranged in a circumferential array of 8-10.

[0008] As an improvement of this utility model, a water inlet pipe is provided on the bottom surface of the water boiler.

[0009] A tea ceremony machine, characterized in that it includes the anti-siphon structure described in any one of the above claims.

[0010] As an improvement of this utility model, the tea maker includes an outer casing and a control panel disposed on the casing and electrically connected to the water pump and the water boiler. The casing has a through hole through which the water outlet nozzle passes.

[0011] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0012] This invention features a pluggable upper and lower section of the water outlet pipe at its underwater landing section. An axially serrated groove is machined on the outer wall of the upper section at the pluggable point to serve as a venting channel. This structure allows external air to naturally enter the pipe after the water pump stops, breaking the vacuum and thus achieving an anti-siphon function. The serrated shape of the venting channel provides a stable airflow path and is not easily blocked. The design of evenly distributing multiple venting channels along the circumference ensures reliable air intake regardless of how the pipe sections are rotated or assembled. Placing the water inlet pipe at the bottom of the boiler simplifies internal piping connections and reduces the impact on the water inside the boiler and the generation of bubbles during water replenishment. This tea maker, integrating this anti-siphon structure, avoids abnormal water output caused by siphoning, prevents water accumulation inside the equipment and the resulting electrical risks, and improves the stability and lifespan of the product.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0021] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way. Example

[0022] like Figure 1-2As shown, an anti-siphon structure for a tea maker includes: a water boiler 3, with a water outlet pipe 31 installed at the bottom of the water boiler 3. The water outlet pipe 31 is divided into a water rising section 314, a horizontal flow section 315, and a water falling section 316 from the bottom of the water boiler 3. A water pump 32 is provided in the water rising section 314. The water falling section 316 is divided into an upper water outlet pipe section 311 and a lower water outlet pipe section 312. The upper water outlet pipe section 311 is inserted into the lower water outlet pipe section 312, and a venting groove 313 is provided in the inserted part of the upper water outlet pipe section 311. This structure designs the outlet pipe 31 as a specific path including a rising water section 314, a horizontal flow section 315, and a falling water section 316. A venting groove 313 is provided at the connection point between the upper section 311 and the lower section 312 of the outlet pipe in the falling water section 316. When the water pump 32 stops working, external air can quickly enter the connection between the upper section 311 and the falling water section 316 through the venting groove 313, effectively disrupting any negative pressure that may form within the pipe. This significantly prevents continuous abnormal outflow or backflow of water from the boiler 3 due to the siphon effect. The structure is simple and the anti-siphon effect is reliable. The venting groove 313 is a serrated groove axially arranged on the outer wall of the upper section 311 of the outlet pipe. A serrated groove extending axially is used as the venting groove 313. This creates a stable and non-clogging micro-airway after the upper section 311 and lower section 312 of the outlet pipe are connected, ensuring smooth airflow into the pipe. The serrated structure also provides a larger effective ventilation area, further enhancing the response speed and reliability of the anti-siphon function. Eight to ten venting grooves 313 are arranged in a circumferential array. Evenly distributing these 8 to 10 venting grooves 313 circumferentially ensures that a sufficient number of venting grooves 313 are always in an effective working state, regardless of the relative rotation of the upper section 311 and lower section 312 of the outlet pipe. This provides multiple parallel air intake channels, significantly improving the stability and fault tolerance of the anti-siphon function and preventing functional failure due to blockage of a single channel or improper placement. A water inlet pipe 33 is provided on the bottom surface of the water boiler 3. Setting the water inlet pipe 33 on the bottom of the water boiler 3 makes the water replenishment path more direct, which helps to simplify the internal pipe layout of the tea machine. At the same time, this bottom water inlet design helps to reduce the bubbles and disturbances that may be generated inside the water boiler 3, making the water replenishment process more stable and smooth. Example

[0023] like Figure 3-4 As shown, a tea maker includes the anti-siphon structure described in any one of the above claims. By integrating any one of the aforementioned anti-siphon structures, the tea maker possesses highly efficient and reliable anti-siphon capabilities, effectively preventing water waste, internal water accumulation, and potential electrical safety hazards caused by siphoning during machine shutdown, significantly improving the overall machine's operational stability and service life.

[0024] As an improvement of this utility model, the tea maker includes an outer casing 1 and a control panel 2 mounted on the casing 1 and electrically connected to the water pump 32 and the boiler 3. The casing 1 has a through hole 12 for the water outlet 11 to pass through. The control panel 2 is connected to a controller (such as a PLC), which controls the start of the water pump 32 and the boiler 3. The boiler 3 also has a temperature sensor to provide real-time temperature feedback to the controller (the components and connections described here are examples of existing technology and will not be elaborated upon). The through hole 12 on the casing 1 allows the water outlet 11 to extend securely outside the machine, facilitating water intake for the user. The through hole 12 also positions and protects the water outlet 11, ensuring the integrity and aesthetics of the overall structure of the tea maker and facilitating the connection and installation of the water outlet 11 with the internal anti-siphon pipe.

[0025] Working principle: When water pump 32 starts, it pumps water from the boiler 3 through the rising section 314 of the outlet pipe 31, flows through the horizontal section 315, enters the falling section 316, and finally exits through the outlet nozzle 11. When water pump 32 stops working, a negative pressure may form in the pipeline due to the liquid level difference, creating a siphon tendency. At this time, external air enters the pipeline through the vent groove 313 set at the connection between the upper section 311 and the lower section 312 of the outlet pipe, quickly balancing the pressure inside and outside the pipeline, thereby effectively blocking the siphon path and preventing water from the boiler 3 from being abnormally drawn out.

[0026] In summary, this utility model incorporates a pluggable upper and lower section of the water outlet pipe at its underwater drop section. An axially serrated groove is machined on the outer wall of the upper section at the pluggable point to serve as a venting channel. This structure allows external air to naturally enter the pipe after the water pump stops, breaking the vacuum and thus achieving an anti-siphon function. The serrated shape of the venting channel provides a stable airflow channel that is not easily blocked. The design of evenly distributing multiple venting channels along the circumference ensures reliable air intake regardless of how the pipe sections are rotated or assembled. Placing the water inlet pipe at the bottom of the boiler simplifies internal piping connections and reduces the impact on the water inside the boiler and the generation of bubbles during water replenishment. This tea maker, integrating this anti-siphon structure, avoids abnormal water output caused by siphoning, prevents water accumulation inside the equipment and the resulting electrical risks, and improves the stability and lifespan of the product.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
