Description

Technical Field

[0001] This utility model belongs to the field of water cup technology, and in particular relates to a water cup with a heating device. Background Technology

[0002] Currently, most water cups on the market with heating devices are electric cups, which only provide a single function of boiling water. Therefore, their structure can only support the function of electric cups and cannot be expanded to provide more functions, such as providing both hand warming and water boiling functions at the same time. This existing structure usually includes a cup body for holding water and a heating base, with the base screwed to the bottom of the cup body. The cup body adopts a single-layer or double-layer structure, such as the technical solution shown in patent CN119837399A, an electric cup.

[0003] To enable the water cup heating device to provide more functions, there is an urgent need to design a new structure. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a water cup with a heating device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A water cup with a heating device includes an inner cup for holding liquid, with a radially outward limiting platform on its upper part; a lid that covers the mouth of the inner cup; an outer cup fitted over the outer side of the inner cup, comprising at least an outer cup body and a bottom cover; a heating device that is tightly attached to the inner wall of the outer cup body and / or the outer wall of the inner cup; a control module located in the space between the inner and outer cups for electrically controlling the opening and closing of the heating device, comprising at least a bracket, a battery, a circuit board, and a switch assembly; the bracket is fixed to the bottom of the inner cup, the battery is located inside the bracket, and the circuit board is located at the bottom of the bracket; the switch assembly includes at least a switch button exposed on the outer surface of the outer cup body; the bottom cover is fixedly connected to the bracket, while the outer cup body is clamped and fixed between the bottom cover and the limiting platform.

[0007] Using the above technical solution, the control module can be fixed to the inner cup by setting a bracket, and the bottom cover can be fixed to the bracket. By setting a limiting platform on the upper part of the inner cup, the outer cup body can be clamped and fixed between the limiting platform and the bottom cover. Through ingenious structural design, the fixing and integration of various components can be completed. Moreover, the outer cup is not welded to the inner cup, which makes it easy for the heating device to be selectively fixed to the inner side wall of the outer cup (for warming hands). The heating device can also be selected to be set on the outer side wall or the outer bottom wall of the inner cup (for supplementing the temperature of the liquid in the cup). Therefore, this structure has greater scalability.

[0008] Preferably, the heating device includes a hand warmer and an inner cup heater; the hand warmer is in close contact with the inner wall of the outer cup; the inner cup heater is in close contact with the outer wall of the inner cup.

[0009] The above technical solution can provide both hand warming and liquid replenishment heating functions simultaneously.

[0010] Preferably, the heating device includes a hand-warming heating element that is closely attached to the inner wall of the outer cup body.

[0011] The above technical solution can provide a separate hand-warming function.

[0012] Preferably, the heating device includes an inner cup heating element that is closely attached to the outer wall of the inner cup.

[0013] The above technical solution can provide a separate function for heating and replenishing the temperature of the liquid inside the cup.

[0015] Using the above technical solution, the sealing ring is made of elastic sealing material and fits tightly against the upper end of the outer cup body for sealing. The upper end of the sealing ring also abuts against the limiting platform for sealing. This achieves a seal between the outer cup and the inner cup, preventing moisture from entering the interlayer. Moreover, the sealing ring has buttons that correspond to the switch button. The buttons, made of elastic material, have a very good feel. This structure is very ingenious. The plasticity of the sealing ring can also be used for decoration, giving the sealing ring more integrated functions.

[0016] Preferably, the bottom cover is also provided with a glue-filling hole, and the gap between the bottom cover, the outer cup body, and the control module is sealed by filling the glue-filling hole with sealant.

[0017] Using the above technical solution, the gap between the bottom cover and the outer cup body and the control module is sealed by filling the glue hole with sealant. Thus, the interlayer space between the inner cup and the outer cup can become a sealed space, preventing moisture from entering and damaging components such as the control module, hand warmer, and inner cup heating element. This sealing method can provide a better waterproof rating. It has been tested and can be cleaned and disinfected in a dishwasher, with a rating of IP68 or higher.

[0018] Preferably, the side wall of the bottom cover is also fitted with a sealing ring that abuts against the outer cup body to form a seal.

[0020] Preferably, the bottom cover is fixedly connected to the bracket by screws through the screw holes thereon; and a sealing gasket is provided between the screw holes and the screws.

[0021] The above technical solution uses screw fixing, which is simple and mature in structure; and by setting a sealing gasket, the sealing performance is further ensured.

[0022] Preferably, the upper circumferential end of the outer cup body is provided with several limiting notches; the inner wall of the sealing ring is provided with corresponding limiting ribs; the limiting ribs are inserted into the limiting notches to restrict the rotation of the sealing ring.

[0023] By adopting the above technical solution, the rotation of the sealing ring can be restricted by setting a limiting notch and a limiting rib.

[0024] Preferably, the control module also includes a wireless charging coil attached to the bottom surface of the bottom cover.

[0025] By adopting the above technical solution, a wireless charging coil is set up to facilitate battery charging; moreover, by placing it close to the bottom surface of the bottom cover, it can be closer to the charger, resulting in higher charging efficiency.

[0026] Preferably, the inner cup includes an inner liner, an inner shell, and a connecting ring; the inner shell is located outside the inner liner, and the inner liner and the inner shell are welded together at the upper end; the lower outer wall of the inner liner and the lower outer wall of the inner shell are respectively welded to the inner side wall and the outer side wall of the connecting ring; the interlayer formed by the inner liner, the outer shell, and the connecting ring is a vacuum layer; the heating element of the inner cup is closely attached to the outer bottom wall of the inner liner, and a heat insulation component is also provided between the heating element of the inner cup and the battery.

[0027] By adopting the above technical solution and setting up heat insulation components, the risk of heat affecting the battery when the inner cup heating element is heated can be avoided; moreover, the inner cup is set with a double-layer vacuum structure, which allows the liquid temperature inside the inner cup to be maintained for a longer time, making it more convenient to carry for long periods of time and more energy-efficient; in addition, with this vacuum structure, the bottom of the inner cup is the bottom of the inner liner, and the inner cup heating element can heat the liquid inside the inner cup.

[0028] Preferably, the control module is also equipped with an indicator light group; a light guide strip is sealed and fixed on the opening on the side wall of the outer cup; the indicator light group and the light guide strip are set accordingly.

[0029] By adopting the above technical solution, light groups can be set up to provide visual prompts such as power-on, hand warming, inner cup reheating, battery level, and charging; and light guides can be set up to conduct light and soften the light.

[0030] Preferably, the switch assembly also includes a switch cable; a switch button is located at the upper end of the switch cable; an indicator light group is located on the switch cable; a fixing bracket is also provided on the outer side of the inner cup and is clamped and fixed between the bracket and the limiting platform; the switch cable is fixed in a slot on the outer wall of the fixing bracket.

[0031] By adopting the above technical solution, the fixing bracket can be used to fix the switch cable and set the light group on the switch cable, which simplifies the structure and reduces the wiring harness; moreover, the fixing bracket can be cleverly clamped between the bracket and the limiting platform.

[0032] Preferably, the inner wall of the outer cup body is provided with a guide positioning groove corresponding to the slot; the slot guide is inserted into the guide positioning groove.

[0033] By adopting the above technical solution, the guide positioning groove is set to facilitate the directional installation of the outer cup body.
