Technical Field
[0001] This utility model relates to the field of water boiling equipment technology, and in particular to a heat-insulating water boiling cup. Background Technology
[0002] With technological advancements and improved living standards, electric kettles are increasingly used in various scenarios. Existing electric kettles typically consist of a lid and a body, with a heating element inside to heat the water. The heated water then needs to be kept warm for consumption. Currently, the common method for keeping kettles warm is to create a vacuum layer between the inner liner and the outer shell, effectively locking in the heat of the beverage. However, the vacuum layer on the side wall of the kettle involves numerous manufacturing steps and is relatively complex, resulting in high production costs if a good insulation effect is achieved. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0031] use Figure 1 , Figure 1 This is a front view of the present invention. A heat-insulating water kettle is described below. This heat-insulating water kettle can heat drinking water, and the heated water can be insulated and kept warm for convenient use by the consumer; alternatively, a freezing medium can be added inside the kettle to keep it cold.
[0032] like Figure 1 and Figure 2 The overall structure of this heat-insulating water kettle is described as shown. Figure 1 This is the front view of the present invention. Figure 2 This is a cross-sectional view of the present invention.
[0033] This insulated water kettle includes a cup body 1, a lid assembly 2, and a heating assembly 3; wherein:
[0034] The cup body 1 includes an outer shell 4 and an inner liner 5. The inner liner 5 is located in the inner cavity of the outer shell 4 and can be used to hold drinking water.
[0035] The lid assembly 2 is located on the cup body 1. Specifically, the lid assembly 2 is sealed to the mouth of the cup body 1 with a detachable mounting structure to lock in the heat of the beverage inside.
[0036] The heating component 3 is located at the bottom of the cup body 1 and is used to heat the inner liner 5 in the cup body 1, thereby heating the drinking water in the inner liner 5.
[0037] Reference Figure 3 As shown. Figure 3 This is a perspective view of the inner liner of this utility model. A flexible heat insulation layer 6 is provided on the outer wall of the inner liner 5, and the flexible heat insulation layer 6 can wrap around the outer wall of the inner liner 5.
[0038] Reference Figure 4 As shown. Figure 4This is a schematic diagram of the internal structure of the flexible insulation layer 6 in this invention. The flexible insulation layer 6 is a silica aerogel flexible insulation layer with a porous internal molecular structure forming a nanoporous body 7. The pore size of the nanoporous body 7 is between 10 and 50 nm, which is much smaller than the mean free path of air molecules (approximately 68 nm). Therefore, gas molecules are difficult to collide freely in the pores, forming a "molecular barrier" effect that significantly inhibits the conduction of heat by the gas. The porosity of the flexible insulation layer 6 is 90%, while its density is 0.03 g / ml, and its thermal conductivity is only about 0.014 W / m·K, exhibiting extremely low thermal conductivity. Thus, the flexible insulation layer 6, wrapped around the outside of the inner liner 5, can be used for the thermal insulation of the inner liner 5. Compared to the existing complex vacuum layer structure for thermal insulation, the flexible insulation layer 6 only needs to be attached and installed to the outer wall of the inner liner 5, resulting in fewer manufacturing steps, a relatively simple process, and lower costs.
[0039] In addition, the flexible insulation layer 6 can effectively reduce thermal conductivity while meeting the requirements of flame retardancy, insulation and environmental protection, which is conducive to improving the performance of the kettle.
[0040] In some embodiments, such as Figure 2 As shown. Figure 2 This is a cross-sectional view of the present invention. The cup lid assembly 2 includes a cup lid and a venting structure. The cup lid can be installed onto the mouth of the cup body 1. The venting structure includes a venting slot and a waterproof and breathable membrane. The venting slot is opened onto the cup lid and is connected to the inner liner 5. The waterproof and breathable membrane is located at the bottom of the venting slot.
[0041] In this embodiment, the heating element 3 heats the inner liner 5. The hot steam generated by the drinking water in the inner liner 5 can pass through the waterproof and breathable membrane and be discharged to the outside of the lid along the vent. In addition, the waterproof and breathable membrane also has a waterproof function, which can prevent water in the inner liner 5 from leaking to the outside of the lid along the vent. Therefore, when boiling water in the kettle, there is no need to remove the lid to complete the boiling process.
[0042] In some embodiments, such as Figure 2 As shown. Figure 2 This is a cross-sectional view of the present invention. The heating assembly 3 includes a water temperature probe 301, a heating plate assembly 302, a heat insulation bracket 303, and a control board assembly 304.
[0043] The water temperature probe 301 is located at the bottom of the inner tank 5 and can be used to monitor the water temperature inside the inner tank 5.
[0044] The heating plate assembly 302 is installed on the bottom surface of the inner liner 5 to heat the bottom of the inner liner 5, thereby heating the drinking water in the inner liner 5.
[0045] A heat insulation bracket 303 is installed at the bottom of the heating plate assembly 302, while a control board assembly 304 is installed at the bottom of the heat insulation bracket 303. Both the water temperature probe 301 and the heating plate assembly 302 are electrically connected to the control board assembly 304. The control board assembly 304 contains a control circuit or control program. Based on the data monitored by the water temperature probe 301, the control board assembly 304 can intelligently control the heating plate assembly 302 to heat the drinking water in the inner tank 5.
[0046] In some embodiments, such as Figure 1 As shown. Figure 1 This is a front view of the present invention. A display screen 8 and a button 9 are provided on the surface of the outer casing 4. Both the display screen 8 and the button 9 are electrically connected to the control board assembly 304. The display screen 8 can display the heating temperature parameters, and the button 9 can be used to turn the kettle on and off, or to adjust the kettle's boiling mode.
[0047] In some embodiments, such as Figure 2 As shown. Figure 2 This is a cross-sectional view of the present invention. To securely install the inner liner 5 into the outer shell 4, an inner liner bracket 501 is installed at the top of the inner liner 5, and the top of the inner liner 5 is mounted to the outer shell 4 via the inner liner bracket 501.
[0048] In addition, in order to install the cup lid assembly 2 onto the mouth of the cup body 1, the outer wall of the inner liner bracket 501 is provided with threads, and the cup lid assembly 2 can be threaded onto the inner liner bracket 501.
