Description

Technical Field

[0001] This invention relates to the field of milk maker technology, and specifically to a milk maker. Background Technology

[0002] Currently, most formula makers on the market have the mixing chamber located below the powder dispenser, with the powder outlet corresponding to the mixing chamber. When preparing formula, the powder falls from the outlet into the mixing chamber, mixes with hot water, and then dispenses the formula. After preparing the formula, the mixing chamber usually needs to be cleaned and dried to prevent bacterial growth.

[0003] For example, utility model patent CN223489519U discloses a milk mixing device with hot air drying capability. This prior art uses a water pump to clean the mixing chamber through the inlet after the milk powder is prepared, and then dries the mixing chamber with a hot air assembly to prevent bacterial growth. However, in this prior art, the hot air assembly is located above the mixing chamber. When preparing milk, the steam from the hot water rises, causing sticky gases to adhere to the hot air assembly, making it dirty and affecting its performance over time.

[0004] Therefore, there is still room for improvement and development in existing technologies. Summary of the Invention

[0005] To address the problems of existing technologies, this invention proposes a milk maker that uses hot water pipes and hot air pipes to perform high-temperature cleaning and high-temperature drying and sterilization of the mixing chamber, which can prevent the growth of bacteria in the mixing chamber.

[0006] To achieve the above objectives, the technical solution applied in this invention is as follows: A formula maker includes a main unit with a powder box and a mixing chamber assembly. The mixing chamber assembly contains a mixing cavity. The main unit has a hot water pipe and a hot air pipe connected to the mixing cavity. This design allows for high-temperature cleaning of the mixing cavity using the hot water pipe after formula preparation, followed by drying and sterilization using the hot air pipe, effectively preventing bacterial growth within the mixing cavity.

[0007] According to the above scheme, a one-way valve is installed on the pipeline between the hot gas pipeline and the mixing chamber, and the outlet of the one-way valve is connected to the mixing chamber through the pipeline. This configuration prevents hot gas backflow through the check valve's backflow prevention function.

[0008] According to the above scheme, the hot gas pipeline includes an air pump and a heating module. The air pump's inlet is connected to the outside via a pipeline, the air pump's outlet is connected to the heating module's inlet via a pipeline, and the heating module's outlet is connected to the one-way valve's inlet via a pipeline. This configuration allows outside gas to be introduced by the air pump, heated by the heating module, and then supplied to the mixing chamber via the one-way valve, achieving the purpose of high-temperature hot gas drying and sterilization.

[0009] According to the above scheme, the heating module includes an upper cover, a heating element, and a lower cover. The upper and lower covers are fixedly connected to form a receiving cavity. The heating element is located inside the receiving cavity. The lower cover is provided with an air inlet, and the upper cover is provided with an air outlet. The air inlet is connected to the air outlet of an air pump through a pipeline, and the air outlet is connected to the air inlet of a one-way valve through a pipeline. With this configuration, external gas is introduced into the receiving cavity through the air pump, heated into hot gas by the heating element, and then supplied to the mixing cavity through the air outlet and the one-way valve.

[0010] According to the above scheme, the hot water pipeline includes a water tank, a metering pump, and a heating element. The outlet of the water tank is connected to the inlet of the metering pump via a pipeline, the outlet of the metering pump is connected to the inlet of the heating element via a pipeline, and the outlet of the heating element is connected to the mixing chamber via a pipeline. With this configuration, the metering pump draws a fixed amount of water into the heating element, heats it into hot water, and then supplies it into the mixing chamber.

[0011] According to the above scheme, a temperature sensor is installed on the pipeline between the water outlet of the metering pump and the water inlet of the heating element, and a temperature sensor is installed on the pipeline between the water outlet of the heating element and the mixing chamber. This configuration allows the water temperature to be detected in real time by the temperature sensors, enabling the heating element to heat the water to a preset temperature.

[0012] According to the above scheme, a T-junction is installed on the pipeline between the temperature sensor and the water inlet of the heating element, and the T-junction is connected to an air pump. This arrangement allows the air pump to blow air into the pipeline when the hot water supply stops, preventing residual moisture from remaining in the pipeline.

[0013] According to the above scheme, a one-way valve 2 is installed on the pipeline between the three-way pipe and the second air pump. The air inlet of the second air pump is connected to the outside through the pipeline, and the air outlet of the second air pump is connected to the air inlet of the second one-way valve through the pipeline. The air outlet of the second one-way valve is connected to the three-way pipe. This configuration, through the backflow prevention function of the second one-way valve, prevents the backflow of gas and moisture.

[0014] According to the above scheme, the mixing chamber assembly includes a mixing chamber, a chamber cover, and a pressure cap. The chamber cover is fixed on the mixing chamber, and the mixing chamber is provided with a water inlet. The chamber cover is provided with an air outlet and an air inlet. The pressure cap is fixed on the chamber cover and forms an air guiding channel, which is connected to the air outlet and the air inlet. The water inlet is connected to a hot water pipeline through a pipe. The air outlet is connected to a hot air pipeline through a pipe.

[0015] According to the above scheme, the host is equipped with a water receiving tray, which is located below the mixing chamber assembly.

[0016] Beneficial effects of this invention: This invention employs a design where, after milk preparation, the mixing chamber is cleaned at high temperature using a hot water pipe, and then dried and sterilized using a hot air pipe, effectively preventing bacterial growth within the mixing chamber. The hot air pipe is located within the main unit and dries and sterilizes the mixing chamber using hot air. Compared to existing hot air components, this design effectively solves the problem of dirt accumulation and provides a more ideal sterilization effect through high-temperature hot air.

[0020] like Figures 1 to 13 As shown, this invention provides a formula maker, including a main unit with a powder box 1 and a mixing chamber assembly. The mixing chamber assembly contains a mixing cavity. The main unit has a hot water pipe and a hot air pipe connected to the mixing cavity. This configuration allows for high-temperature cleaning of the mixing cavity using the hot water pipe after formula preparation, followed by drying and sterilization using the hot air pipe, effectively preventing bacterial growth within the mixing cavity.

[0021] The hot air pipeline is installed inside the main unit and dries and disinfects the mixing chamber with hot air. Compared with the existing hot air components, it effectively solves the problem of dirt and grime, and the disinfection effect is more ideal through high-temperature hot air.

[0022] The hot water pipe can be used to prepare milk powder and clean the mixing chamber.

[0023] Furthermore, such as Figure 6 , 13 As shown, a one-way valve 24 is installed on the pipeline between the hot gas pipeline and the mixing chamber, and the outlet of the one-way valve 24 is connected to the mixing chamber through the pipeline. This configuration prevents hot gas backflow through the check valve 24's backflow prevention function.

[0024] Furthermore, the hot air pipeline includes an air pump 12 and a heating module 23. The air inlet of the air pump 12 is connected to the outside via a pipeline, and the air outlet of the air pump 12 is connected to the air inlet of the heating module 23 via a pipeline. The air outlet of the heating module 23 is connected to the air inlet of the one-way valve 24 via a pipeline. This configuration allows outside air to be introduced by the air pump 12, heated by the heating module 23, and then supplied to the mixing chamber via the one-way valve 24, achieving the purpose of high-temperature hot air drying and sterilization.

[0025] Furthermore, such as Figure 6, 7 As shown, the heating module 23 includes an upper cover 25, a heating element 26, and a lower cover 27.

[0028] Furthermore, a T-junction 13 is provided on the pipeline between the temperature sensor 16 and the water inlet of the heating element 17, and the T-junction 13 is connected to an air pump 15 via a pipeline. With this configuration, when the hot water supply stops, the air pump 15 blows air into the pipeline to prevent residual moisture in the pipeline.

[0029] Furthermore, a one-way valve 14 is installed on the pipeline between the three-way pipe 13 and the second air pump 15. The air inlet of the second air pump 15 is connected to the outside through the pipeline, and the air outlet of the second air pump 15 is connected to the air inlet of the second one-way valve 14 through the pipeline. The air outlet of the second one-way valve 14 is connected to the three-way pipe 13.
