Technical Field

[0001] The utility model belongs to the technical field of water-boiling heating bases, in particular to a water-boiling heating base with an anti-dry-boiling structure. Background Art

[0002] Common coffee cups or similar thermoses on the market are placed on a fixed heating base. The methods for controlling heating and heat preservation are usually: 1. Using the gravity of the cup body and liquid to act on a mechanical switch or touch switch to turn on the heating function; 2. The user operates a button or touch switch to turn on the heating function; 3. Other methods such as infrared rays and induction switches detect that the cup body is placed in a fixed position and turn on the heating function.

[0003] The above three methods are simple and effective in structure, and can implement the control of the heating function, and even detect and infer the temperature of the liquid in the cup through temperature sensors or time settings. However, it is difficult to control the amount of liquid in the cup, especially when there is a lack of liquid. It is difficult to prevent the heating function from dry burning. Secondly, there is an annular groove on the top of the existing heating base, which can be used to position the container at the top. However, when there is a lot of water in the container, some water will overflow when the water boils and slide along the outer wall of the container into the annular groove. After long-term accumulation, it will cause erosion to the heating base.

[0004] Therefore, in order to solve the above problems, a water heating base with an anti-dry-burning structure is proposed. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a water heating base with an anti-dry-boiling structure, comprising a base housing, wherein a heating coil, a PBCA, and a gravity sensor are respectively installed in the base housing, and an annular positioning groove is formed on the top surface of the base housing, and a water collection component is connected to the annular positioning groove;

[0007] The water collection assembly includes a U-shaped water pipe connected to the annular positioning groove, and the U-shaped water pipe is connected to a water storage pad, and the water storage pads are evenly distributed on the bottom of the base shell.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, the present invention provides a water heating base with an anti-dry-burning structure, including a base shell 1. A heating coil 2, a PBCA 3, and a gravity sensor 4 are respectively installed in the base shell 1. The gravity sensor 4 is used to judge the capacity change inside the container. When there is no water in the container, the heating coil 2 can be controlled to stop running to avoid dry-burning. Secondly, the water level inside the container can be judged according to the water level in the container, and then heating or heat preservation can be performed. The top surface of the base shell 1 is concave to form an annular positioning groove 5, and the annular positioning groove 5 is connected to a water collection component 6;

[0028] The water collection component 6 includes a U-shaped water pipe 601 connected to the annular positioning groove 5. The U-shaped water pipe 601 is connected to a water storage pad 602. The water storage pad 602 is evenly distributed at the bottom of the base shell 1. After water accumulates in the annular positioning groove 5, the accumulated water will be introduced into the water storage pad 602 through the U-shaped water pipe 601 to avoid a large amount of accumulated water from corroding the heating base.

[0029] Specifically, the base shell 1 is composed of a base upper shell 101 and a base lower shell 102. The annular positioning groove 5 is provided on the base upper shell 101. The base shell 1 is composed of two parts, the upper and lower parts, so that the base shell 1 can be disassembled and the internal structure can be inspected.

[0030] Furthermore, a heat dissipation through hole 7 is provided on the base lower shell 102 , and an elastic fastener 8 is provided at a position on the base lower shell 102 corresponding to the base upper shell 101 .

[0031] Furthermore, the water storage foot pad 602 includes an upper cover 6021, the top of the upper cover 6021 is fixedly connected to the lower shell 102 of the base, and the upper cover 6021 is threadedly connected to the water storage cylinder 6022. The water storage foot pad 602 is composed of two parts: the upper cover 6021 and the water storage cylinder 6022. When too much water accumulates inside the water storage foot pad 602, the water storage cylinder 6022 can be unscrewed to pour out the accumulated water.

[0032] It is worth noting that a connecting pipe 9 is connected between adjacent upper covers 6021, and a U-shaped water pipe 601 is connected to one of the upper covers 6021. The U-shaped water pipe 601 guides water into the water storage pad 602 connected thereto. When the water level therein reaches the connection position of the connecting pipe 9, the excess water can be guided into the adjacent water storage pad 602, thereby increasing the storage capacity.

[0033] It is worth noting that a threaded ring section 10 is formed on the top of the water storage cylinder 6022 , and the threaded ring section 10 is threadedly connected to the internal thread of the inner wall of the upper cover 6021 .

[0034] It is worth mentioning that a non-slip pad 11 is provided at the bottom of the water storage foot pad 602 to prevent the bottom of the water storage foot pad 602 from sliding.

[0035] Among them, the heating coil 2 and the gravity sensor 4 are existing technologies and will not be described in detail; at the same time, the present invention also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0036] Working principle and process: After the water storage container is placed on the heating base, the gravity sensor 4 can sense the pressure on the heating base, and control the wireless coil 2 to turn on the heating or insulation function according to the algorithm (not limited to wireless heating methods, such as PTC heating, etc.), and prompt consumers with different indicator light states. If there is any abnormality, the system will enter a dormant state if no human intervention is taken within the specified time. According to the different states of the water storage container, the system working mode is as follows (not limited to this mode): 1. When an empty cup is identified (the weight of the water storage container), the indicator light flashes, and if there is no human operation for 5 minutes, it will enter the sleep state to prevent dry boiling; 2. When an overcup is identified (exceeding a certain weight of a full cup), the indicator light flashes, and if there is no human operation for 5 minutes, it will enter the sleep state to prevent dry boiling; 3. When no cup is identified (the weight is less than the weight of the water storage container), the indicator light flashes, and if there is no human operation for 5 minutes, it will enter the sleep state to prevent dry boiling; 4. When a full cup is identified (the weight of the water storage container plus the full liquid), the indicator light is always on, and the system is in the heating or heat preservation state; 5. When a half cup is identified (the weight of the water storage container plus part of the liquid), the indicator light is always on , for heating or insulation state. Compared with other common technologies in the market, the advantage is that the system can give different working states according to the changes in the amount of water in the water storage container, preventing dry burning to save resources and reduce safety risks. When water accumulates in the annular positioning groove 5 due to overflow and spillage, the accumulated water will be introduced into the water storage foot pad 602 through the U-shaped water guide pipe 601 to avoid a large amount of accumulated water from corroding the heating base. When the water level in the water storage foot pad 602 reaches the connection position of the connecting pipe 9, the excess water can be introduced into the adjacent water storage foot pad 602, thereby enhancing the storage capacity. When too much water accumulates inside the water storage foot pad 602, the water storage cylinder 6022 can be unscrewed to pour out the water accumulated in the water storage foot pad 602.
