DETAILED DESCRIPTION

[0050] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0051] Please refer to Figures 1 to 7 The utility model provides a water boiling device, comprising: a glass container 11, a first bracket 12, a heating plate 13, a first base 14, an elastic support member 15, and a heater 16;

[0052] The bottom side of the glass container 11 is clamped with the first bracket 12, and its bottom surface is in contact with the top surface of the heating plate 13 with a thermal grease layer provided between the two.

[0053] The first bracket 12 is arranged along the top edge of the first base 14;

[0054] The bottom surface of the heating plate 13 is connected to the first end of the elastic support member 15 and is pressed toward the bottom surface of the glass container 11 through the elastic support member 15;

[0055] The second end of the elastic support member 15 is disposed in an inner area surrounded by the edge of the top surface of the first base 14;

[0056] The heater 16 is disposed on the bottom surface of the heating plate 13 .

[0057] In this embodiment, the glass container 11 can be made of a high-temperature resistant and explosion-proof glass material (such as high borosilicate glass). The glass container 11 is not only resistant to high temperatures, but also convenient for observing the water level inside the container. The first bracket 12 can be a high-temperature resistant plastic bracket. The heating plate 13 can be a ceramic heating plate or a metal heating plate, which has the characteristics of rapid heating and good thermal stability. The shape of the heating plate 13 matches the bottom shape of the glass container 11 to ensure uniform heat transfer. The thermal grease layer uses high-performance thermal grease to fill the gap between the heating plate 13 and the glass container 11. It has excellent thermal conductivity and insulation properties, which can ensure efficient heat transfer. The first base 14 can be a high-temperature resistant bracket base.

[0058] During specific implementation, the glass container 11 can be made of high borosilicate glass, which has good heat resistance and can withstand instantaneous temperature differences. The capacity can be designed to be 0.3-0.5 liters. The heating plate 13 can be made of a ceramic heating plate with a diameter of 60-80 cm, which has the characteristics of high thermal efficiency and long life. The power of the heating plate 13 can be 300 watts, which can quickly heat water to boiling. The thermal grease in the thermal grease layer can be made of high-performance thermal grease with a thermal conductivity of 2.0-4.0W / (m·K). This grease can maintain stable thermal conductivity in the temperature range of -50°C to 200°C. The following steps are included when setting the thermal grease layer: first, clean the heating plate 13 and the bottom of the glass container 11 to ensure that there is no dust and oil; then, use a scraper or brush and a steel mesh with a thickness of 0.1-0.3mm to evenly apply an appropriate amount of thermal grease on the heating surface of the heating plate 13 to form a thermal grease layer; finally, place the heating plate 13 coated with thermal grease on a stable table, align the bottom of the glass container 11 with the heating plate 13, and gently place it to ensure that the thermal grease is evenly distributed and the heating plate 13 is in close contact with the bottom of the glass container 11.

[0059] The water boiling device in the present application realizes a fast, efficient and safe water boiling function through the combination of the heating plate 13, the thermal grease layer and the glass container 11. It has the advantages of simple structure, high thermal efficiency, energy saving and environmental protection, and is suitable for various occasions such as home, office, travel, etc.

[0060] In one possible implementation, Figure 4 and Figure 7 , the elastic support member 15 includes a spring 151;

[0061] The bottom surface of the heating plate 13 is provided with a support 131;

[0062] The support 131 is correspondingly disposed inside the spring 151;

[0063] The heating plate 13 is supported on the first base 14 by the support 131 and the spring 151 , and the spring 151 is in a compressed state.

[0064] In this embodiment, both the spring 151 and the pillar 131 can be of conventional design. In a specific implementation, four bare pillars, i.e., pillars 131, can be provided on the back, i.e., bottom, of the heating plate 13, and the four springs 151 are respectively mounted on the four pillars 131. The spring 151 is in a compressed state, with one end of the spring 151 resting on the bracket base, i.e., the first base 14, and the other end resting on the back of the heating plate 13, so that the heating plate 13 can always be in close contact with the bottom surface of the glass container 11. The pillar 131 can limit the deformation range of the spring 151, preventing the spring 151 from being damaged due to excessive compression.

[0065] In one possible implementation, Figure 2 and Figure 3 The bottom side of the glass container 11 is provided with a limiting protrusion 111;

[0066] The first bracket 12 is provided with a slot 121;

[0067] The limiting protrusion 111 cooperates with the locking groove 121 to achieve locking.

[0068] In this embodiment, by providing the limiting protrusion 111 and the locking groove 121, the stability of the glass container 11 can be improved, and the glass container 11 can be prevented from shaking during the water boiling process, thereby improving safety.

[0069] In one possible implementation, Figure 8 and Figure 9 , a silicone ring 112 is provided on the bottom side of the glass container 11;

[0070] The silicone ring 112 is provided with an opening 1121;

[0071] The limiting protrusion 111 passes through the opening 1121 and is engaged with the locking slot 121 .

[0072] In this embodiment, the silicone ring 112 is made of elastomeric silicone and is disposed around the bottom side of the glass container 11. After the first bracket 12 compresses the silicone ring 112, it can be screwed to the first base 14 to secure it, thereby facilitating the fixing of the glass container 11 and the heating plate 13 together and preventing the glass container 11 from shaking.

[0073] In one possible implementation, Figure 1 、 Figures 10 to 12 , the glass container 11 includes a first cylindrical container body and a second cylindrical container body;

[0074] The bottom surface of the first cylindrical container body is larger than the bottom surface of the second cylindrical container body;

[0075] A transition ring 113 is provided at the connection between the first cylindrical container body and the second cylindrical container body;

[0076] A second bracket 114 is provided between the transition ring 113 and the first bracket 12 .

[0077] In this embodiment, by providing a transition ring 113 and a second bracket 114, part of the downward pressure of the glass container 11 can be transferred to the first bracket 12 through the second bracket 114, and finally transferred to the first base 14, thereby reducing the pressure on internal components such as the heating plate 13, preventing damage to the internal structure, and improving the service life of the water boiling device.

[0078] In one possible implementation, Figure 13 A thermistor 115 is provided on the bottom side of the glass container 11.

[0079] In this embodiment, the thermistor 115 may be an NTC type, and may be used to detect the water temperature in the glass container 11 .

[0080] In a possible implementation, a water level sensor 116 is provided on the bottom side of the glass container 11 .

[0081] In this embodiment, the water level sensor 116 can be a conventional non-contact capacitive liquid level gauge. The water level sensor 116 can be placed in close contact with the outer surface of the glass container 11. For example, the water level sensor 116 can be wrapped with an elastomeric silicone rubber that conforms to the shape of the glass container 11 to prevent it from loosening. The water level sensor 116 can be used to detect the water level in the glass container 11 to prevent dry boiling.

[0082] In one possible implementation, Figure 14 A temperature sensor 17 is provided in the space constructed between the heating plate 13 and the first base 14 .

[0083] In this embodiment, the temperature sensor 17 can be arranged near the heating plate 13 to monitor the temperature of the heating plate 13 in real time. When the temperature value detected by the temperature sensor 17 exceeds a set threshold, the heater 16 can be controlled to stop heating to prevent the heating plate 13 from overheating. The temperature sensor 17 can be installed close to the bottom surface of the heating plate 13. For example, a metal pressing plate can be provided to press the temperature sensor 17 to the bottom surface of the heating plate 13. A screw column is provided on the bottom surface of the heating plate 13. The screw column passes through the metal pressing plate and is locked with a nut. In this way, the temperature sensor 17 can be fixed to the bottom surface of the heating plate 13.

[0084] In one possible implementation, Figure 15 , a second base 18 is provided below the first base 14;

[0085] A control module 19 is disposed in the space between the first base 14 and the second base 18 .

[0086] In this embodiment, the control module 19 is implemented based on a control circuit and can control the operating state of the heater 16 based on the monitoring data of relevant sensors. The control module 19 can also be provided with a corresponding power interface 191 and a start button. The control module 19 can control the heating time and temperature of the heater 16 to set different water heating modes (such as rapid heating mode, energy-saving mode, constant temperature mode, etc.) to meet the needs of different users.

[0087] In one possible implementation, Figure 1 、 Figure 15 、 Figure 16 A container cover 20 is provided on the top of the glass container 11.

[0088] In this embodiment, the glass container 11 and container lid 20 can be movably connected using snap fasteners or rotatably closed using internal and external threads. A filter 201 can also be provided on the container lid 20, with a filter cover 202 provided on the filter 201. The first bracket 12, heating plate 13, first base 14, elastic support member 15, heater 16, etc. can be disposed within a base housing 21, with the lower portion of the glass container 11 connected to the upper portion of the base housing 21.

[0089] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
