Description

Technical Field

[0001] This utility model relates to the field of thermos kettle technology, and in particular to a movable pipe gravity-discharge thermos kettle. Background Technology

[0002] With the improvement of modern living standards and the increasing sophistication of maternal and infant care needs, smart thermos flasks, as an important product in the maternal and infant product field, are gradually becoming common equipment in family feeding scenarios. These products aim to provide convenience for scenarios such as preparing infant formula, simplifying the feeding process and improving safety, through precise temperature control and quantitative water dispensing.

[0003] However, the current market-available thermostatic kettles with metered water dispensing have significant limitations in their technical design, mainly in the following aspects: Relying on water pumps and long pipes, these thermos flasks are prone to bacterial growth: Most existing thermos flasks use a water pump system, with some also incorporating solenoid valves and long silicone pipes for water flow control. The continuous noise generated by the pump disrupts the quiet environment of the home, especially for infants and young children. Furthermore, the internal structure of the pump and the long silicone pipes means that water residue can easily remain after the water flows through. This residual water lingers in the pipes for extended periods, creating a breeding ground for bacteria and posing a potential risk to the health of mothers and infants.

[0004] The pipe wastewater drainage function is defective: Although some products claim to have a pipe wastewater drainage function, in actual use, the residual water often needs to be left until the next brewing before it can be drained. During this period, it will still be left to stand for several hours or even longer. The problem of bacterial growth cannot be fundamentally solved, making it difficult to meet the strict hygiene requirements of maternal and infant products.

[0005] User pain points caused by complex structure: The combination of water pumps, solenoid valves, and long pipelines not only increases the manufacturing cost and failure rate of the equipment, but also reduces the stability of the product due to the complexity of multiple components working together. In addition, the bends in the long pipelines and sealing problems at the joints further aggravate the generation of water leakage and cleaning dead spots, affecting the user experience and equipment lifespan.

[0006] Therefore, it is necessary to design a movable pipe gravity-discharge thermostatic kettle to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-5A movable pipe gravity-discharge thermostatic kettle includes a main body 6. A full glass kettle 1 is mounted on the upper end of the main body 6. A lower coupler 5 is installed on the upper end of the main body 6, and an upper coupler 2, which cooperates with the lower coupler 5, is installed on the lower end of the full glass kettle 1. The cooperation between the upper coupler 2 and the lower coupler 5 not only achieves a stable connection between the full glass kettle 1 and the main body 6, but also transmits circuit signals through the coupling structure, providing power support for the heating and thermostatic function of the full glass kettle 1. A water outlet column 11 is connected to the lower end of the full glass kettle 1. A water outlet 12, connected to the water outlet column 11, is located at the bottom of the full glass kettle 1. A main body pipe 61 is connected to the upper end of the main body 6. A main body outlet 62 is located at the lower end of the main body pipe 61. A movable plug assembly 3 is provided between the main body pipe 61 and the water outlet column 11. The movable plug assembly 3 includes a movable plug fixing bracket 3 fixedly connected to the upper end of the main body pipe 61. 7. The movable plug fixing bracket 37 is a metal frame structure, which is fixed to the body pipe 61 by screws. The upper end of the body 6 is fixedly connected to the movable plug pull rod fixing bracket 35, which is also made of metal and has a U-shaped structure. The inner walls of the left and right sides of the movable plug pull rod fixing bracket 35 are rotatably connected to the movable plug pull rod 36. The movable plug fixing bracket 37 has a through hole, the size of which matches the outer diameter of the movable plug through hole tube 32. The movable plug through hole tube 32 is slidably connected through the through hole. The movable plug through hole tube 32 and the movable plug fixing bracket 37 are elastically connected by a compression spring 34. The upper end of the movable plug through hole tube 32 is fixedly connected to two L-shaped blocks. The upper ends of the two L-shaped blocks are fixedly connected to a rubber stopper sealing plug 31. The rubber stopper sealing plug 31 is made of food-grade silicone material, which has good elasticity and sealing performance. Under normal conditions, it can tightly fit the water outlet 12 of the kettle to achieve a water seal.

[0019] The movable plug through-hole pipe 32 contains a movable plug pipe 322 located within the water outlet column 11 of the kettle. The upper end of the movable plug pipe 322 has a movable plug inlet 321 located between two L-shaped blocks. The lower end of the movable plug through-hole pipe 32 extends into the body pipe 61. A waterproof rubber ring 33, a ring-shaped silicone structure, is fitted onto the outer wall of the movable plug pipe 32, tightly fitting the movable plug through-hole pipe 32 and the water... The inner wall of the kettle water column 11 prevents water from leaking through the gap between the movable plug through-hole tube 32 and the kettle water column 11. The movable plug pull rod 36 includes a rectangular block and a U-shaped block. The left and right sides of the rectangular block are rotatably connected to the movable plug fixing frame 37. The movable plug through-hole tube 32 includes a vertical tube. A ring is fixedly connected to the outer wall of the vertical tube. The U-shaped block is located at the upper end of the ring. When the movable plug pull rod 36 rotates, the U-shaped block can press down on the ring, causing the movable plug through-hole tube 32 to move downward.

[0020] The upper end of the main body 6 is equipped with a movable plug power assembly 4. The movable plug power assembly 4 includes a motor mounting bracket 44, a motor 43 is installed inside the motor mounting bracket 44, and a toggle handle 42 is fixedly connected to the end of the output shaft of the motor 43. A push rod 41 is fixedly connected to the lower end of the rectangular block. The push rod 41 is T-shaped and its lower end contacts the toggle handle 42. When the toggle handle 42 rotates, it can push the push rod 41 to move upward, thereby driving the movable plug pull rod 36 to rotate.

[0021] The main body 6 has a placement slot on the front side, the water outlet 62 is located at the top inside the placement slot, the baby bottle 7 is placed at the bottom inside the placement slot, and an electronic scale 8 is installed at the bottom inside the placement slot. The main body 6 has an operation panel on the front side, and a control system is installed inside the main body 6. The electronic scale 8 is electrically connected to the control system of the main body 6, which can detect the amount and weight of water in the baby bottle 7 in real time and feed the signal back to the control system to control the stop of water dispensing.

[0022] The functional principle of this utility model can be explained by the following operation: Under normal conditions, the rubber stopper sealing plug 31 in the movable plug assembly 3 tightly blocks the water outlet 12 of the all-glass water bottle 1 under the action of the compression spring 34, preventing water from flowing out.

[0023] When a specific amount of water needs to be dispensed, a command is issued via the control panel on the main body 6, and the signal is transmitted to the motor 43 of the movable plug power assembly 4. The motor 43 rotates and drives the lever 42 to rotate. The lever 42 pushes the push rod 41 upward, which in turn drives the rectangular block in the movable plug pull rod 36 of the movable plug assembly 3 to move upward, causing one end of the U-shaped block to rotate downward. This causes the movable plug through-hole tube 32 to move the rubber stopper sealing plug 31 downward, and the compression spring 34 is compressed. This action causes the rubber stopper sealing plug 31 to leave the water bottle outlet 12. Under the action of gravity, the water in the all-glass water bottle 1 flows sequentially through the movable plug inlet 321, the movable plug pipe 322, and the main body pipe 61, and finally flows from the main body outlet 62 into the baby bottle 7 placed on the electronic scale 8.

[0024] When the electronic scale 8 reaches the set quantitative water volume, it sends a signal to the motor 43, which drives the actuating handle 42 to rotate. At this time, the push rod 41 and the movable plug pull rod 36 return to their original state under the elastic force of the compression spring 34, and the rubber stopper sealing plug 31 re-blocks the water outlet 12 of the kettle, thereby stopping the water flow and completing one quantitative water dispensing operation.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
