Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to an automatic discharge structure for residual wastewater in pipelines and its milk maker. Background Technology

[0002] As a core small appliance in infant feeding, the formula maker delivers purified water or formula liquid from the storage container to the bottle at a precise temperature and flow rate, ensuring that the formula is diluted to the specified concentration in the shortest possible time, preventing clumping and maximizing nutrient retention. However, in actual operation, after a formula preparation process is completed and the pump stops, the pipes are not emptied but retain residual water, commonly known as wastewater. This wastewater is caused by a combination of factors, including residual pressure in the pump chamber, adhesion to the pipe walls, and gravity backflow. When the next formula preparation command is triggered, the pump restarts. Because the pipes already contain wastewater, the old and new liquids mix in the pump chamber and pipes. On the one hand, the lower temperature of the wastewater often results in the actual temperature reaching the spout being lower than the formula's requirements; on the other hand, the prolonged retention of residual wastewater in the pipes may breed trace bacteria or adsorb material molecules precipitated from the pipe walls. These potential contaminants, when mixed with fresh liquid, enter the bottle directly, posing hygiene risks and ultimately affecting the infant's feeding experience and gastrointestinal comfort.

[0003] Therefore, it is necessary to disclose an automatic discharge structure for residual wastewater in pipelines and its milk maker to overcome the shortcomings of existing technologies. Utility Model Content

The inlet end of the solenoid valve is connected to the inlet pipe, and the outlet end of the solenoid valve is connected to a water delivery pipe. The solenoid valve is used to control the flow of fluid between the inlet pipe and the water delivery pipe.

[0007] It also includes a T-pipe, which has a first port, a second port and a third port; wherein the first port is connected to the water supply pipe, the second port is connected to the inlet end of the water pump, and the outlet end of the water pump is connected to an outlet pipe;

[0010] In the waste discharge mode, the solenoid valve is closed and the water pump is working, which will create a negative pressure in the water supply pipe and the three-way pipe. At this time, outside air enters the third port of the three-way pipe through the one-way air valve to replenish the air supply and promote the discharge of residual wastewater.

[0011] Furthermore, the one-way valve is a silicone one-way valve.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 3 As shown, this utility model claims protection for an automatic discharge structure for residual wastewater in pipelines, including a water pump 1, an inlet pipe 2, a solenoid valve 3, a three-way pipe 5, and a one-way air valve 6. Specifically, the water pump 1 is a key component providing fluid power, including an inlet end and an outlet end. The inlet end is connected to the second port 502 of the three-way pipe 5, and the outlet end is connected to the outlet pipe. Its function is to provide power for the flow of fluid in normal drainage and waste discharge modes, enabling water to flow in the pipeline along a set path. The inlet pipe 2, as the water inlet channel of the entire structure, is responsible for introducing external water into the system and is the starting point of the entire drainage system.

[0031] In this embodiment, the solenoid valve 3 is a two-way solenoid valve 3, with its inlet end connected to the water inlet pipe 2 and its outlet end connected to the water delivery pipe 4. The main function of the two-way solenoid valve 3 is to control the flow of fluid between the water inlet pipe 2 and the water delivery pipe 4. When the solenoid valve 3 is energized, the valve opens, allowing fluid to flow from the water inlet pipe 2 to the water delivery pipe 4; when the solenoid valve 3 is de-energized, the valve closes, preventing fluid from passing through, thereby achieving precise control of the water flow.

[0032] In this embodiment, the tee pipe 5 has a T-shaped structure with a first port 501, a second port 502, and a third port 503. The first port 501 is connected to the water supply pipe 4, the second port 502 is connected to the water inlet of the water pump 1, and the third port 503 is vertically located at the top of the tee pipe 5. The first port 501 and the second port 502 are horizontally axially connected. This structural design allows the fluid to flow smoothly in the horizontal direction, while the vertical setting of the third port 503 provides a suitable position for the installation of the one-way air valve 6 and the entry of air.

[0033] The one-way air valve 6 is a silicone one-way air valve, installed on the third port 503 of the three-way pipe 5. The silicone material has good flexibility, corrosion resistance, and sealing properties, ensuring the normal operation of the one-way air valve 6. Its function is to allow outside air to enter the three-way pipe 5 when a negative pressure is formed in the water supply pipe 4 and the three-way pipe 5 during waste discharge mode, while preventing fluid leakage from the third port 503 of the three-way pipe 5 during normal drainage mode.

[0034] The working principle of this automatic residual wastewater discharge structure is as follows:

[0035] Normal drainage mode: When the system is in normal drainage mode, solenoid valve 3 and water pump 1 are turned on. At this time, external water enters through inlet pipe 2, passes through the energized two-way solenoid valve 3, flows into water supply pipe 4, then enters water pump 1 through the first port 501 and the second port 502 of three-way pipe 5, and finally is discharged from the outlet end of water pump 1 through outlet pipe, realizing the normal drainage function.

[0036] Waste Discharge Mode: When waste discharge is required, solenoid valve 3 closes while water pump 1 continues to operate. Due to the suction effect of water pump 1, the pressure in water delivery pipe 4 and three-way pipe 5 decreases, creating a negative pressure. At this time, under the action of the pressure difference, outside air enters the third port 503 of three-way pipe 5 through silicone one-way air valve 6, replenishing the pressure in the pipe. This causes the residual wastewater in the pipe to be discharged under the combined action of air pressure and the suction of water pump 1, achieving the purpose of automatic discharge of residual wastewater.

[0037] like Figure 4As shown, this utility model also claims protection for a formula maker, which includes the above-mentioned automatic discharge structure for residual wastewater in the pipeline, as well as components such as a base 7, a mounting base 8, a water storage container 9, and a heating device 10, providing users with a convenient formula making experience.

[0038] Specifically, the formula maker includes a base 7, which supports the entire formula maker and ensures its stability. A mounting base 8 is fixed above the base 7, and an automatic wastewater discharge mechanism is built into the mounting base 8. This design makes the formula maker more compact and reduces its space requirements.

[0039] The front end of the mounting base 8 is equipped with a water outlet 802, which is in fluid communication with the water outlet pipe. In normal drainage mode, water that has been treated by the automatic discharge structure for residual wastewater in the pipeline can flow out through the water outlet 802, making it convenient for users to collect hot water to prepare formula.

[0040] The mounting base 8 has a recessed placement groove 801 at its top, and the water storage container 9 is detachably placed in the placement groove 801. The detachable design makes it convenient for users to clean, add water, and perform other operations on the water storage container 9, keeping the water storage container 9 clean and hygienic.

[0041] The water storage container 9 is equipped with a handle 11, which allows users to easily pick up or move the water storage container 9 by holding the handle 11, thus improving the convenience of use.

[0042] The mounting base 8 is equipped with a heating device 10 for heating the water storage container 9. The heating device 10 can heat the water in the water storage container 9 to a suitable temperature to meet the user's needs for preparing milk powder. The heating device 10 is existing technology and will not be described in detail here.

[0043] The formula maker operates as follows: water in the storage container 9 is heated by the heating device 10 and then enters the automatic residual wastewater discharge structure through the inlet pipe 2. During normal formula preparation, the solenoid valve 3 is open, the water pump 1 operates, and hot water is discharged from the outlet 802 through the water supply pipe 4, the three-way pipe 5, the water pump 1, and the outlet pipe. After formula preparation, the system automatically switches to the waste discharge mode, the solenoid valve 3 closes, and the water pump 1 uses negative pressure suction and one-way air valve 6 to replenish air, thoroughly discharging the residual wastewater in the water supply pipe 4, the three-way pipe 5, and the outlet pipe, ensuring that the pipeline is dry and clean, and improving the hygiene and safety of the formula maker.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
