Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water cup technology, and in particular relates to an electric hot water cup. Background Technology
[0002] With the improvement of people's living standards and the increasing demand for healthy drinking water, electric water cups, as a convenient and efficient water heating appliance, have been widely used in daily life and office environments. Existing electric water cups typically consist of a cup body for storing water and a base fixed to the cup body. The base contains a heating element to quickly heat the water. However, in actual use, because the heating element generates a large amount of heat when operating, this heat not only affects the water but may also be conducted to electronic components inside the base, such as the power supply and control circuitry, leading to a series of problems.
[0003] First, the traditional structure lacks effective heat insulation, causing heat from the heating chamber to easily diffuse to the power supply area. Prolonged exposure to high temperatures can lead to aging, performance degradation, and even failure of electronic components, affecting the product's lifespan and stability. Second, poor heat dissipation can also cause safety hazards, such as short circuits and material deformation due to excessive heat. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an electric hot water cup with good heat insulation and heat dissipation effects.
[0005] The objective of this utility model can be achieved through the following technical solution: an electric hot water cup, comprising:
[0006] The cup body is used to store water;
[0007] The cup holder is fixed to the cup body. An installation cavity is provided inside the cup holder, and a heat insulation plate is fixedly installed inside the installation cavity, dividing the installation cavity into a heating cavity and a heat dissipation cavity. A heating element is fixedly installed inside the heating cavity, and a power supply unit is provided inside the heat dissipation cavity, electrically connected to the heating element. A heat dissipation passage is provided on the heat insulation plate to connect the heating cavity and the heat dissipation cavity. An air vent is provided on the outer wall of the cup holder, communicating with the heat dissipation cavity.
[0008] In the aforementioned electric water cup, the vent is located on the bottom wall of the cup base.
[0009] In the aforementioned electric water cup, the lowest surface of the vent is higher than the lowest surface of the cup base in the vertical direction, and the bottom wall of the cup base is provided with a venting channel to enable the vent to communicate with the external space.
[0010] In the aforementioned electric hot water cup, a control circuit board is fixedly installed inside the heat dissipation cavity. The control circuit board is located between the heat insulation plate and the power supply unit, and there is a gap between the control circuit board and the cavity wall of the heat dissipation cavity to form a flow space.
[0011] In the aforementioned electric hot water cup, the flow space and the heating element are respectively located near the inner wall of the mounting cavity that is opposite to each other.
[0012] In the above-mentioned electric water cup, a surrounding plate is fixedly installed inside the heat dissipation cavity and covers the power supply unit. Part of the edge of the surrounding plate is fixedly connected to the inner wall of the heat dissipation cavity, while the remaining edge of the surrounding plate has a gap with the inner wall of the heat dissipation cavity to form a communicating space. A fixing plate is provided in the communicating space, and a flow-blocking part is provided on the side of the fixing plate near the air outlet.
[0013] In the aforementioned electric water cup, a lid is hinged to the cup body, and a torsion spring is provided between the lid and the cup body. When the lid is placed on the cup body, the torsion spring is in a compressed and energy-storing state. A damping part is provided on the cup body, and a moving part is provided on the lid. The moving part and the damping part are interference-fitted, and the two can slide relative to each other.
[0014] In the aforementioned electric hot water cup, a limiting part is provided on the damping part, and an abutting part is provided on the cup lid. When the cup lid is opened to the limit position, the limiting part abuts against the abutting part, thereby limiting the relative angle between the cup lid and the cup body.
[0015] In the aforementioned electric hot water cup, the cup lid is provided with a vent hole, and a water-blocking plug is fixedly provided on the cup lid for sealing connection with the cup mouth. The water-blocking plug has a through cavity, and a waterproof and breathable membrane is fixedly provided between the water-blocking plug and the cup lid. A condensation plate is provided inside the water-blocking plug, and a flow hole is provided on the condensation plate. Water vapor flows through the flow hole toward the waterproof and breathable membrane.
[0016] In the aforementioned electric hot water cup, a connecting bracket is provided at the bottom of the cavity of the water-blocking plug, the bottom of the water-blocking plug is an inclined guiding surface, and the position of the water-blocking plug near the hinge point of the cup lid is higher than the opposite side.
[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: The cup holder is equipped with a heat insulation plate, dividing the mounting cavity into upper and lower independent heating and heat dissipation chambers. The heating element is fixed inside the heating chamber, and the heat it generates first fills the heating chamber, then enters the heat dissipation chamber through the heat dissipation passage on the heat insulation plate, and finally is discharged through the vent on the outer wall of the cup holder. This structure allows heat to be transferred along a predetermined path, avoiding disorderly diffusion of heat directly into the heat dissipation chamber. In particular, it effectively reduces the temperature in the area where the power supply unit is located, reducing the impact of high temperatures on the power supply components, thereby extending the service life of the electric water cup and improving overall safety and stability.

Detailed Implementation
[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0029] like Figures 1-7 As shown, an electric water kettle includes:
[0030] Cup body 100, cup body 100 is used for water storage;
[0031] The cup holder 200 is fixed to the cup body 100. The cup holder 200 has an installation cavity, and a heat insulation plate 201 is fixedly installed in the installation cavity, dividing the installation cavity into a heating cavity 202 and a heat dissipation cavity 203. A heating element 212 is fixedly installed in the heating cavity 202, and a power supply unit 211 is installed in the heat dissipation cavity 203 and electrically connected to the heating element 212. A heat dissipation passage cavity 213 is provided on the heat insulation plate 201 to realize the communication between the heating cavity 202 and the heat dissipation cavity 203. An air vent 204 is provided on the outer wall of the cup holder 200 and is connected to the heat dissipation cavity 203.
[0032] In this embodiment, a heat insulation plate 201 is provided inside the cup holder 200, dividing the mounting cavity into an upper and lower independent heating cavity 202 and a heat dissipation cavity 203. The heating element 212 is fixed in the heating cavity 202. The heat generated by the element first fills the heating cavity 202, then enters the heat dissipation cavity 203 through the heat dissipation passage 213 on the heat insulation plate 201, and finally is discharged through the vent 204 on the outer wall of the cup holder 200. This structure allows heat to be transferred along a set path, avoiding the disorderly diffusion of heat directly into the heat dissipation cavity 203. In particular, it effectively reduces the temperature of the area where the power supply unit 211 is located, reduces the impact of high temperature on the power supply unit 211, thereby extending the service life of the electric water cup and improving the overall safety and stability.
[0033] It should be noted that the power supply unit 211 is a built-in battery with a power storage function. In the absence of an external power source, the power supply unit 211 can be used to power the heating element 212. The cup holder 200 is provided with a charging port 214 that is electrically connected to the power supply unit 211. The charging port 214 includes a triangular charging port and a Type-C charging port. The charging port 214 is also provided with a movable sealing cover to prevent dust or moisture from entering the charging port 214.
[0034] It is worth mentioning that the cup body 100 has a double-layer vacuum structure, which is heat-insulating and cold-insulating, ensuring that the outer wall will not get hot to the touch during use.
[0035] Preferably, the vent 204 is located on the bottom wall of the cup holder 200. This prevents high-temperature gas from being directly discharged onto the upper part or side of the cup holder 200 that the user frequently touches, thereby reducing the risk of the user being burned by accidentally coming into contact with the discharged hot gas.
[0036] Furthermore, in the vertical direction, the lowest surface of the vent 204 is higher than the lowest surface of the cup holder 200, and the bottom wall of the cup holder 200 is provided with a venting channel 205 to enable the vent 204 to communicate with the external space.
[0037] As shown in the figure, the heat insulation plate 210 is provided with multiple heat dissipation cavities 213. The heating element 212 is positioned close to one of the heat dissipation cavities 213, so that the heat generated by the heating element 212 can directly enter the heat dissipation cavity 203, or fill the heating cavity 202 and then enter the heat dissipation cavity 203 through other heat dissipation cavities 213.
[0038] In this embodiment, firstly, the lowest surface of the vent 204 is higher than the bottom of the cup holder 200, ensuring that after the cup is placed on the support surface, there is a gap between the vent 204 and the support surface to ensure normal airflow. At the same time, it can also effectively prevent external liquids (such as water stains on the table or cleaning water) from flowing back into the cup holder 200 through the vent 204, thereby avoiding short circuits or damage to the internal power supply unit 211 and improving the safety and reliability of the product.
[0039] It is worth mentioning that the bottom wall of the cup holder 200 protrudes upward, making the vent 204 higher than the lowest surface of the cup holder 200, and a rubber ring 206 is provided at the bottom of the cup holder 200 to raise it, with the vent channel 205 located on the rubber ring 206.
[0040] Preferably, a control circuit board 207 is fixedly installed inside the heat dissipation cavity 203. The control circuit board 207 is located between the heat insulation plate 201 and the power supply unit 211, and there is a gap between the control circuit board 207 and the cavity wall of the heat dissipation cavity 203 to form a flow space.
[0041] In this embodiment, the control circuit board 207 serves as an additional heat insulation layer, further reducing the possibility of heat generated by the heating element 212 being transferred to the power supply unit 211. This provides an additional protective barrier for the power supply unit 211, helping to maintain its operating temperature within a safe range, thereby improving the safety and stability of the device. The design of using the control circuit board 207 as both a core component for circuit connections and a heat insulation layer saves space and simplifies the structure, which is beneficial for the lightweight and miniaturization of the product.
[0042] The flow space and heating element 212 are further positioned close to the inner walls of the mounting cavity, respectively. This causes hot air entering the heat dissipation cavity 203 from the heating cavity 202 via the heat dissipation passage 213 on the heat insulation plate 201 to travel a longer path towards the vent 204. This longer flow path also means that the hot air has more opportunities to be naturally cooled or gradually discharged through the vent 204, preventing localized overheating. Because the flow space is positioned on the inner wall near the vent 204, while the heating element 212 is located on the other side, the hot air must bypass structures such as the control circuit board 207 and the enclosure 208 before finally being discharged; the hot air does not directly impact the power supply unit 211 but moves slowly along the flow path, reducing thermal shock to the power supply unit 211.
[0043] Preferably, a surrounding plate 208 is fixedly installed inside the heat dissipation cavity 203 and covers the power supply unit 211. Part of the edge of the surrounding plate 208 is fixedly connected to the inner wall of the heat dissipation cavity 203, while the remaining edge of the surrounding plate 208 has a gap with the inner wall of the heat dissipation cavity 203 to form a communicating space. A fixing plate 209 is provided in the communicating space, and a flow-blocking part 210 is provided on the side of the fixing plate 209 near the air outlet 204.
[0044] In this embodiment, the flow-blocking section 210 includes a flow-blocking plate integrally and vertically disposed on the fixed plate 209. The flow-blocking plate is located within the flow space, and the flow-blocking plate and the surrounding plate 208 are not connected to form a sealed space, which can effectively block or slow down the reverse flow of hot air to the power supply section 211 area. In addition, since the power supply section 211 itself also generates a certain amount of heat when it is working, this heat can be smoothly guided to the vent 204 and discharged through the connecting space and the cooperation between the fixed plate 209 and the flow-blocking section 210, avoiding the accumulation in the power supply section 211 and causing the temperature to be too high.
[0045] Furthermore, a cup lid 300 is hinged to the cup body 100, and a torsion spring is provided between the cup lid 300 and the cup body 100. When the cup lid 300 is placed on the cup body 100, the torsion spring is in a compressed and energy-storing state. A damping part 301 is provided on the cup body 100, and a moving part 302 is provided on the cup lid 300. The moving part 302 and the damping part 301 are interference-fitted, and the two can slide relative to each other.
[0046] In this embodiment, a torsion spring is provided between the lid 300 and the cup body 100. When the lid 300 is closed, the torsion spring is in a compressed and energy-storing state. Once the lid 300 begins to open from the closed state, the torsion spring releases energy to help push the lid 300 open. The interference fit between the moving part 302 and the damping part 301 and their relative sliding generate a certain frictional resistance, which effectively reduces the opening speed of the lid 300. This ensures that even during the automatic opening process under the action of the torsion spring, a relatively slow speed is maintained, reducing the risk of water splashing caused by rapid opening.
[0047] Furthermore, the damping part 301 is provided with a limiting part 303, and the cup lid 300 is provided with an abutting part 310. When the cup lid 300 is opened to the limit position, the limiting part 303 abuts against the abutting part 310, thereby limiting the relative angle between the cup lid 300 and the cup body 100.
[0048] When the user opens the cup lid 300 to its maximum angle, the limiting part 303 abuts against the abutting part 310, ensuring that the cup lid 300 will not close automatically due to accidental collision or gravity. This is especially important for users while drinking water, as it can prevent inconvenience or even injury caused by the sudden closing of the cup lid 300.
[0049] Specifically, the limiting part 303 includes a limiting surface provided on the damping part 301. Along the opening and rotation direction of the cup lid 300, the limiting surface gradually protrudes outward. So, during the opening process of the cup lid 300, as the cup lid 300 flips open, the distance between the abutting part 310 and the limiting part 303 gradually decreases until the abutting part 310 and the limiting part 303 are in interference fit and pass over the limiting surface.
[0050] Preferably, the cup lid 300 is provided with a vent hole 304, and a water-blocking plug 305 is fixedly provided on the cup lid 300 for sealing connection with the cup mouth. The water-blocking plug 305 is provided with a through cavity. A waterproof and breathable membrane is fixedly provided between the water-blocking plug 305 and the cup lid 300. A condensation plate 306 is provided inside the water-blocking plug 305. A flow hole 307 is provided on the condensation plate 306. Water vapor flows towards the waterproof and breathable membrane through the flow hole 307.
[0051] In this embodiment, the waterproof and breathable membrane is located between the water-blocking plug 305 and the cup lid 300. It allows gas to pass through while effectively preventing liquid leakage and keeping the inside of the container dry. The condensation plate 306, which is set in the water-blocking plug 305, has flow holes 307. Water vapor can flow through these holes toward the waterproof and breathable membrane. The condensation plate 306 helps to condense some of the water vapor and reduce the amount of water entering the waterproof and breathable membrane.
[0052] In a further preferred embodiment, the bottom of the cavity of the water-blocking plug 305 is provided with a connecting bracket 308, the bottom of the water-blocking plug 305 is an inclined guide surface 309, and the position of the water-blocking plug 305 near the hinge point of the cup lid 300 is higher than the opposite side.
[0053] In this embodiment, the connecting bracket 308 is cross-shaped and is located at the bottom of the cavity of the water plug 305, serving as a support and also as part of the flow guide or fixing structure. The bottom of the water plug 305 is designed with an inclined surface, which makes it difficult for liquid to accumulate inside the water plug 305, and facilitates the automatic return of condensate or residual liquid to the cup body 100 along the inclined surface.
[0054] The lower structural design near the hinge point, combined with the inclined surface, forms a natural flow path, making it easier for liquid to flow towards the opening of the cup body 100. When the user opens the cup lid 300, water droplets will not remain on the flip-top surface or be directly splashed out.
