Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to electric kettles. Background Technology

[0002] When an electric kettle heats water, some carbonates in the water crystallize due to decreased solubility, forming limescale and reducing the safety of the drinking water. While some electric kettles filter the water before it enters the kettle, they often remove beneficial mineral ions needed by the human body, such as calcium, magnesium, and iron ions. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes an electric kettle that filters the water through a filter assembly while the water is being poured out of the kettle body, thus avoiding the removal of beneficial mineral ions such as calcium, magnesium, and iron from the water.

A receiving space is provided between the inner wall of the water storage chamber and the filter assembly. A water purification chamber is provided within the filter assembly, and water in the receiving space enters the water purification chamber through the filter assembly.

[0007] According to an embodiment of the electric kettle, the filter assembly is disassembled, water to be heated is added to the water storage chamber, and then the filter assembly is installed on the kettle body. At this time, the water to be heated is located in the receiving space. After the water in the water storage chamber is heated, the water in the receiving space needs to pass through the filter assembly before flowing to the outlet, so that the filter assembly can filter the water. The filtered water flows into the purified water chamber and then flows from the purified water chamber to the outlet. This achieves the effect of filtering the water through the filter assembly when pouring out the water from the kettle body, avoiding the filtration of beneficial mineral ions such as calcium, magnesium, and iron in the water. Furthermore, by setting a purified water chamber in the filter assembly, some of the water in the receiving space can flow into the purified water chamber through the filter assembly first, so that when the user needs water, the water in the purified water chamber can be poured out directly, avoiding the problem of slow water flow caused by filtering the water again when water is needed.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] The following is combined with Figures 1 to 4 The electric kettle of the present invention is described.

[0042] According to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the electric kettle includes a kettle body 1 and a filter assembly 2. The kettle body 1 has a water storage chamber 11 and a water outlet 12 at the upper end. The filter assembly 2 is detachably connected to the end of the water storage chamber 11 near the water outlet 12. The filter assembly 2 extends to the bottom of the kettle body 1 and is at least partially located in the water storage chamber 11. There is a receiving space between the inner wall of the water storage chamber 11 and the filter assembly 2. A water purification chamber is provided inside the filter assembly 2, and the water in the receiving space enters the water purification chamber through the filter assembly 2.

[0043] In use, the filter assembly 2 is disassembled, and water to be heated is added to the water storage chamber 11. The filter assembly 2 is then installed on the kettle body 1, with the water to be heated located within the holding space. After the water in the water storage chamber 11 is heated, the water in the holding space must pass through the filter assembly 2 before flowing to the outlet 12, allowing the filter assembly 2 to filter the water. The filtered water then flows into the purified water chamber and from the purified water chamber to the outlet 12. This achieves the effect of filtering the water through the filter assembly 2 before pouring it out of the kettle body, preventing the removal of beneficial mineral ions such as calcium, magnesium, and iron. Furthermore, by setting a purified water chamber within the filter assembly 2, some water in the holding space can first flow into the purified water chamber through the filter assembly 2. Therefore, when the user needs water, the water in the purified water chamber can be poured out directly, avoiding the problem of slow water flow caused by filtering the water again when needed.

[0044] In one embodiment of the present invention, the filter assembly 2 includes a filter component and a filter element 25. One end of the filter component away from the bottom of the kettle body 1 is sealed to the end of the water storage chamber 11 near the water outlet 12. A flow channel 28 is provided inside the filter component, and an inlet hole communicating with the flow channel 28 is provided on the filter component. The filter element 25 is installed in the flow channel 28.

[0045] When in use, the kettle body 1 is powered on to heat the water in the water storage chamber 11. The inlet is closer to the bottom of the kettle body 1 than the filter element 25. When the water in the water storage chamber 11 is heated to boiling, the air pressure in the water storage chamber 11 is greater than the atmospheric pressure. Therefore, under the pressure difference, the water in the water storage chamber 11 can flow more quickly from the inlet to the filter element 25, and then, after being filtered by the filter element 25, flows into the purified water chamber 22. The water can then flow from the purified water chamber 22 to the outlet 12, and finally out of the outlet 12, providing the user with filtered water. This ensures that when water is poured out of the kettle body 1, the filter element 25 can filter the water, and the filter element and the water storage chamber 11 are sealed together, ensuring that water can only flow from the filter element 25 to the outlet 12, thus guaranteeing the filtration effect and making it easier for the water in the water storage chamber 11 to flow through the filter element 25 to the outlet 12.

[0046] In one embodiment of the present invention, the filter element 25 is disposed at any position in the flow channel 28. In use, the filter element 25 can be installed at any position in the flow channel 28. The filter element 25 can be set at the upper, middle, or lower part of the flow channel 28 or any other suitable position according to actual needs, so that the water in the water storage chamber 11 must pass through the filter element 25 before flowing into the water purification chamber 22, thereby achieving water filtration.

[0047] In one embodiment of the present invention, the filter element 25 is located, for example, at one end of the flow channel 28 near the bottom of the kettle body 1. The water inlet connects the end of the flow channel 28 near the bottom of the kettle body 1 and the receiving space, so that the water in the receiving space flows through the water inlet to the filter element 25, and then flows into the water purification chamber 22 after passing through the filter element 25, thereby achieving water filtration.

[0048] In one embodiment of the present invention, the filter element 25 is located, for example, at one end of the flow channel 28 away from the bottom of the kettle body 1. The water inlet connects the end of the flow channel 28 away from the bottom of the kettle body 1 and the receiving space, so that the water in the receiving space can flow through the water inlet to the filter element 25, and then flow into the water purification chamber 22 after passing through the filter element 25, thereby achieving water filtration.

[0049] In one embodiment of the present invention, the maximum cross-sectional area of ​​the water inlet is smaller than the maximum cross-sectional area of ​​the water storage cavity 11. In use, setting the maximum cross-sectional area of ​​the water inlet to be smaller than the maximum cross-sectional area of ​​the water storage cavity 11 can increase the water pressure at the water inlet, allowing the water in the containing space to pass through the filter element 25 more quickly.

[0050] In one embodiment of this application, the maximum cross-sectional area of ​​the water inlet is 'a', and the maximum cross-sectional area of ​​the water storage chamber 11 is 'b', where 4 ≤ b / a ≤ 100. In use, the maximum cross-sectional area of ​​the water storage chamber 11 is set to 4 to 100 times the maximum cross-sectional area of ​​the water inlet, resulting in higher water pressure at the water inlet and accelerating the flow of water through the filter element 25.

[0051] In one embodiment of the present invention, such as Figure 1 and Figure 2As shown, the filter component includes a connecting seat 21 and a filter rod 24. The connecting seat 21 is sealed to the water storage chamber 11, and a clean water chamber 22 is provided inside the connecting seat 21. The connecting seat 21 is provided with a connecting hole 23 for connecting the clean water chamber 22 and the water outlet 12. The filter rod 24 is located inside the water storage chamber 11, and a flow channel 28 is provided inside the filter rod 24, which connects the clean water chamber 22 and the receiving space. In use, the filter rod 24 is extended into the water storage chamber 11, and the connecting seat 21 is sealed to the water storage chamber 11, thereby forming a semi-sealed cavity between the connecting seat 21 and the inner wall of the water storage chamber 11, so that the water in the receiving space can only flow into the clean water chamber 22 through the filter rod 24. Power is supplied to the kettle body 1, which heats the water in the water storage chamber 11. When the water in the storage chamber is heated to boiling, water vapor is generated in the storage chamber, which increases the air pressure in the storage chamber. A pressure difference is formed between the storage chamber and the filter rod 24. As a result, the water in the storage chamber will flow faster into the filter rod 24 under the action of the pressure difference. After passing through the filter element 25, the water flows into the water purification chamber 22. Then, the water flows through the connection hole 23 to the water outlet 12, so that the user can obtain water that has been heated to boiling and then filtered. In this way, while filtering out scale in the water, beneficial mineral ions such as calcium, magnesium, and iron in the water will not be filtered out.

[0052] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a sealing element 26 is provided on the connecting seat 21. The sealing element 26 abuts against the water storage cavity 11, and the connection point between the sealing element 26 and the water storage cavity 11 is lower than the water outlet 12. In use, by providing the sealing element 26 on the outer wall surface of the connecting seat 21, when the connecting seat 21 is installed in the water storage cavity 11, the sealing element 26 abuts against the water storage cavity 11. That is, at this time, the sealing element 26 is located between the connecting seat 21 and the water storage cavity 11, thereby enabling the connecting seat 21 and the water storage cavity 11 to be sealed together. Furthermore, the connection between the seal 26 and the water storage chamber 11 is lower than the water outlet 12 and the connecting hole 23, so that the water in the water storage chamber 11 can only flow through the filter rod 24, the water purification chamber 22 and the connecting hole 23 in sequence before flowing to the water outlet 12. This can prevent the water in the water storage chamber 11 from flowing to the water outlet 12 from the connection between the connecting seat 21 and the water storage chamber 11, ensuring that all the water in the water storage chamber 11 is filtered before flowing to the water outlet 12, thus ensuring the filtration effect of the electric kettle.

[0053] Specifically, the connecting seat 21 is provided with a mounting groove that matches the seal 26, and the seal 26 engages with the mounting groove. In use, the seal 26 is installed in the mounting groove, with a portion of the seal 26 located within the groove. Then, the connecting seat 21 is installed in the water storage cavity 11, causing the other portion of the seal 26 to abut against the water storage cavity 11, thereby improving the sealing performance of the connection between the connecting seat 21 and the water storage cavity 11.

[0054] In embodiments of the present invention, the seal 26 is, for example, a sealing ring. However, it should be understood that the seal 26 can also be any other suitable structural component with a sealing function.

[0055] In one embodiment of the present invention, the bottom of the water purification chamber 22 is lower than the connection hole 23. In use, the connection hole 23 is positioned above the bottom of the water purification chamber 22, creating a height difference between the bottom of the water purification chamber 22 and the connection hole 23. This allows the water in the water storage chamber 11 to flow through the filter rod 24 into the water purification chamber 22 under pressure difference, temporarily storing the filtered water. When the user needs water, the user tilts the kettle body 1, causing the water in the water purification chamber 22 to flow into the connection hole 23, and then through the connection hole 23 to the outlet 12.

[0056] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a gap 27 is provided between the end of the filter rod 24 away from the connecting seat 21 and the bottom of the kettle body 1. In use, one end of the filter rod 24 is connected to the connecting seat 21. When the filter assembly 2 is installed in the water storage cavity 11, a gap 27 is left between the other end of the filter rod 24, that is, the end of the filter rod 24 away from the connecting seat 21, and the bottom of the kettle body 1, so that the water in the water storage cavity 11 can flow into the filter rod 24 through the gap 27.

[0057] In one embodiment of the invention, the filter rod 24 comprises at least one of a hollow circular tube, a hollow square tube, and a hollow conical tube. However, it should be understood that the filter rod can also be any other suitable shape.

[0058] In embodiments of the present invention, the filter element 25 is, for example, a porous ceramic or porous metal plate or a porous filter screen. However, it should be understood that the filter element 25 can also be made of any other suitable material.

[0059] In embodiments of the present invention, the pore size distribution of the filter element 25 is, for example, between 0.05 μm and 10 μm. In use, by using the filter element 25 with a pore size distribution of any value between 0.05 μm and 10 μm to filter the water in the water storage chamber 11, more than 90% of the scale in the water can be filtered out, improving drinking water hygiene.

[0060] Furthermore, in embodiments of the present invention, the pore size distribution of the filter element 25 is preferably from 0.1 μm to 8 μm. It should be understood that the pore size distribution of the filter element 25 can be any value from 0.1 μm to 8 μm.

[0061] In one embodiment of the present invention, such as Figure 3 and Figure 4As shown, the electric kettle includes a pressure differential component 6, which is connected to the water storage chamber 11. The pressure differential component 6 increases the air pressure inside the water storage chamber 11, making it greater than the air pressure inside the filter assembly 2. During use, by connecting the pressure differential component 6 to the water storage chamber 11, the pressure differential component 6 can increase the air pressure inside the water storage chamber 11. When the water in the water storage chamber 11 is boiled, water vapor is generated inside the water storage chamber 11, causing the air pressure inside the water storage chamber 11 to rise. This creates a pressure difference between the water storage chamber 11 and the filter assembly 2, allowing the water in the water storage chamber 11 to flow more easily through the filter assembly 2 to the outlet 12 under the action of the pressure difference. This increases the filtration speed of the filter assembly 2, thereby increasing the water output speed of the electric kettle. When the water in the water storage chamber 11 is at room temperature, that is, when there is no water vapor in the water storage chamber 11, the pressure difference component 6 can increase the air pressure in the water storage chamber 11, making the air pressure in the water storage chamber 11 greater than the air pressure in the filter assembly 2. This can also create a pressure difference between the water storage chamber 11 and the filter assembly 2, accelerating the flow of water from the water storage chamber 11 to the filter assembly 2. Thus, even when the water in the water storage chamber 11 is not boiling or is at room temperature, a pressure difference can still be formed between the water storage chamber 11 and the filter assembly 2. This pressure difference accelerates the flow of water from the water storage chamber 11 through the filter assembly 2, thereby increasing the filtration speed of the filter assembly 2.

[0062] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the electric kettle includes a pressure differential component 6, which is connected to the filter assembly 2. The pressure differential component 6 is used to reduce the air pressure inside the filter assembly 2, making the air pressure inside the water storage chamber 11 greater than that inside the filter assembly 2. During use, by connecting the pressure differential component 6 to the filter assembly 2, the pressure differential component 6 can reduce the air pressure inside the filter assembly 2. When the water in the water storage chamber 11 is boiled, water vapor is generated inside the water storage chamber 11, causing the air pressure inside the water storage chamber 11 to rise. This creates a pressure difference between the water storage chamber 11 and the filter assembly 2, allowing the water in the water storage chamber 11 to flow more easily through the filter assembly 2 to the outlet 12 under the action of the pressure difference. This increases the filtration speed of the filter assembly 2, thereby increasing the water output speed of the electric kettle. When the water in the water storage chamber 11 is at room temperature, that is, when there is no water vapor in the water storage chamber 11, the pressure difference component 6 can reduce the air pressure in the filter assembly 2, so that the air pressure in the filter assembly 2 is lower than the air pressure in the water storage chamber 11. This can also create a pressure difference between the filter assembly 2 in the water storage chamber 11. Even when the water in the water storage chamber 11 is not boiling or is at room temperature, a pressure difference can still be formed between the water storage chamber 11 and the filter assembly 2. The pressure difference can accelerate the speed at which the water in the water storage chamber 11 passes through the filter assembly 2, thereby increasing the filtration speed of the filter assembly 2.

[0063] In one embodiment of the present invention, the electric kettle may simultaneously include a pressure differential element 6 communicating with the water storage chamber 11 and a pressure differential element 6 communicating with the filter assembly 2. The pressure differential element 6 communicating with the water storage chamber 11 can increase the air pressure within the water storage chamber 11, making the air pressure within the water storage chamber 11 greater than the air pressure within the filter assembly 2. Conversely, the pressure differential element 6 communicating with the filter assembly 2 can decrease the air pressure within the filter assembly 2, making the air pressure within the water storage chamber 11 greater than the air pressure within the filter assembly 2. By increasing the air pressure within the water storage chamber 11 while decreasing the air pressure within the filter assembly 2, the pressure difference between the water storage chamber 11 and the filter assembly 2 can be further increased, making it easier for water in the water storage chamber 11 to flow into the filter assembly 2, thereby further improving the filtration speed of the filter assembly 2.

[0064] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the electric kettle includes an air inlet 3, which is installed on the kettle body 1 or the filter assembly 2. The first end of the air inlet 3 is connected to the containing space. In use, by setting the air inlet 3 on the kettle body 1 or the filter assembly 2, when heating the water in the water storage chamber 11, the second end of the air inlet 3 is blocked, so that the containing space cannot be connected to the outside through the air inlet 3. As a result, when the water in the water storage chamber 11 is heated to boiling, water vapor is generated in the containing space, which increases the air pressure in the containing space. There is a pressure difference between the containing space and the filter assembly 2. Under the action of the pressure difference, the water in the containing space can more easily flow through the filter assembly 2 to the outlet 12. When the water in the water storage chamber 11 is not heated, or when the water in the water storage chamber 11 is at room temperature, the second end of the air inlet 3 can be opened, and then gas can be supplied to the containment space or the gas in the filter assembly 2 can be extracted through the air inlet 3. This causes the air pressure in the containment space to increase or the air pressure in the filter assembly 2 to decrease, creating a pressure difference between the containment space and the filter assembly 2. Thus, even when the water in the containment space is not boiling or is at room temperature, the pressure difference can still accelerate the speed at which the water in the containment space passes through the filter assembly 2, thereby increasing the filtration speed of the filter assembly 2.

[0065] It should be noted that when the water in the containment space is heated to boiling, gas can be simultaneously supplied to the water storage chamber 11 through the air inlet 3, which can further increase the air pressure in the containment space, allowing the water in the containment space to flow more quickly through the filter rod 24 into the water purification chamber 22.

[0066] Specifically, a matching piston can be installed at the second end of the air intake 3. When it is necessary to block the air intake 3, the piston is engaged with the second end of the air intake 3, thus preventing the receiving space from communicating with the outside through the air intake 3. When it is necessary to supply gas into the receiving space through the air intake 3, the piston is pulled out from the second end of the air intake 3, thereby allowing gas to be supplied into the receiving space through the air intake 3. It should be understood that any other suitable structural component or other suitable method can be used to switch the second end of the air intake 3 between opening and closing.

[0067] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the differential pressure unit 6 includes an air supply unit 4, which is connected to the second end of the air intake 3. The air supply unit 4 is used to supply gas to the air intake 3. In use, gas is supplied to the air intake 3 through the air supply unit 4, and the gas is delivered to the receiving space through the air intake 3, thereby increasing the pressure in the receiving space.

[0068] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the differential pressure component 6 includes an exhaust fan, which is connected to the second end of the air inlet 3. The exhaust fan is used to draw away the gas from the air inlet 3. In use, the exhaust fan draws away the gas from the air inlet 3, and the gas is then transported to the outside through the air inlet 3, thereby reducing the pressure of the filter assembly 2.

[0069] In embodiments of the present invention, the air supply component 4 is, for example, an air pump. However, it should be understood that the air supply component 4 can also be any other suitable component with gas delivery function, such as a fan.

[0070] In embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the air intake 3 includes an air intake channel 31 disposed on the connecting seat 21, with the first end of the air intake channel 31 communicating with the accommodating space. In use, opening the second end of the air intake channel 31 allows gas to be supplied into the accommodating space through the second end of the air intake channel 31, thereby increasing the air pressure in the accommodating space. Closing or blocking the air intake channel 31 prevents the accommodating space from communicating with the outside world through the air intake channel 31, thus preventing water vapor leakage from the accommodating space.

[0071] Specifically, such as Figure 3 and Figure 4As shown, a one-way valve 32 is installed in the intake channel 31, allowing gas in the intake channel 31 to flow unidirectionally into the receiving space through the one-way valve 32. In use, by installing the one-way valve 32 in the intake channel 31, gas in the intake channel 31 can only flow unidirectionally into the receiving space through the one-way valve 32, while gas in the receiving space cannot flow to the outside through the one-way valve 32. This allows gas to be supplied to the receiving space through the intake channel 31, increasing the pressure within the receiving space, while preventing gas in the receiving space from flowing to the outside through the intake channel 31, thus avoiding gas leakage from the receiving space.

[0072] In an embodiment of the present invention, the air inlet 3 includes an air inlet pipe disposed on the kettle body 1, and the first end of the air inlet pipe is connected to the water storage chamber 11. In use, opening the second end of the air inlet pipe allows gas to be supplied into the containing space through the second end of the air inlet pipe, thereby increasing the air pressure in the containing space. Closing the second end of the air inlet pipe prevents the containing space from communicating with the outside through the air inlet pipe, thus preventing water vapor leakage from the containing space.

[0073] It should be noted that the air intake 3 may include both an air intake channel 31 and an air intake pipe, and can simultaneously deliver gas into the containment space through both the air intake channel 31 and the air intake pipe, so that the pressure in the containment space can rise rapidly.

[0074] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a connecting component 5 is provided at the connection between the filter assembly 2 and the water storage chamber 11. The connecting component 5 is adapted to connect the filter assembly 2 and the inner wall surface of the water storage chamber 11. In use, the filter assembly 2 and the water storage chamber 11 are connected by the connecting component 5, so that the filter assembly 2 and the water storage chamber 11 are connected together, preventing the filter assembly 2 from coming off during use.

[0075] In an embodiment of the present invention, the connecting component 5 includes a first snap-fit ​​block and a snap fastener that match each other. One of the first snap-fit ​​block and the snap fastener is disposed on the filter component 2, and the other of the first snap-fit ​​block and the snap fastener is disposed on the inner wall surface of the water storage chamber 11. In use, the first snap-fit ​​block and the snap fastener are snapped together, connecting the filter component 2 and the water storage chamber 11 together, preventing the filter component 2 from coming loose during use. When the first snap-fit ​​block is no longer snapped together with the snap fastener, the filter component 2 and the water storage chamber 11 are no longer connected together, allowing the filter component 2 to be removed from the water storage chamber 11 for cleaning or replacement.

[0076] Specifically, in an embodiment of the present invention, the first snap-fit ​​block is disposed on the filter assembly 2, for example, and the snap fastener is disposed on the water storage chamber 11, for example.

[0077] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the connecting component 5 includes a second snap-fit ​​block 51 and a snap-fit ​​hole 52 that cooperate with each other. One of the second snap-fit ​​block 51 and the snap-fit ​​hole 52 is disposed on the filter component 2, and the other of the second snap-fit ​​block 51 and the snap-fit ​​hole 52 is disposed on the inner wall surface of the water storage chamber 11. In use, the second snap-fit ​​block 51 is snapped into the snap-fit ​​hole 52, so that the filter component 2 and the water storage chamber 11 are connected together, preventing the filter component 2 from coming off during use. Removing the second snap-fit ​​block 51 from the snap-fit ​​hole 52 decouples the filter component 2 from the water storage chamber 11, allowing the filter component 2 to be removed from the water storage chamber 11 for cleaning or replacement.

[0078] Specifically, in an embodiment of the present invention, the second snap-fit ​​block 51 is disposed on the filter assembly 2, for example, and the snap-fit ​​hole 52 is disposed on the water storage chamber 11, for example.

[0079] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 5 As shown, the kettle body 1 and / or filter assembly 2 are provided with an exhaust port 7, which is connected to the containment space so that the gas in the containment space can be discharged through the exhaust port 7.

[0080] In use, the filter assembly 2 is installed inside the water storage chamber 11. The kettle body 1 is powered on to heat the water in the water storage chamber 11. When the water in the water storage chamber 11 is heated to boiling, the water vapor generated during heating can be discharged through the vent 7, preventing the air pressure inside the water storage chamber 11 from rising. When the user needs water, the kettle body 1 is tilted towards the outlet 12, so that the water in the water storage chamber 11 flows through the filter assembly 2 to the outlet 12, and then the water flows out from the outlet 12, allowing the user to obtain filtered water. This ensures that when water is poured out of the kettle body 1, the filter assembly 2 can filter the water, keeping the air pressure inside the water storage chamber 11 stable. Therefore, when the kettle body 1 is heating the water in the water storage chamber 11, it is not necessary to remove the filter assembly 2 from the water storage chamber 11.

[0081] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 5As shown, the vent 7 is located on the end of the filter assembly 2 furthest from the outlet 12. During use, the vent 7 is located on the end of the filter assembly 2 furthest from the outlet 12, allowing gas in the water storage chamber 11 to escape through the vent 7. When the user needs water, the kettle body 1 is tilted towards the outlet 12, causing the water in the water storage chamber 11 to also tilt towards the outlet 12. This lowers the water level at the end furthest from the outlet 12, preventing water from flowing from the vent 7 to the outlet 12. The water in the water storage chamber 11 is then filtered by the filter assembly 2 before flowing to the outlet 12, ensuring the filtration effect of the electric kettle.

[0082] In an embodiment of the present invention, the vent 7 is provided, for example, on the end of the kettle body 1 away from the outlet 12. When the kettle body 1 is tilted downward toward the outlet 12, the position of the vent 7 will be higher than the outlet 12, so that the water in the water storage chamber 11 will not be discharged from the vent 7.

[0083] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the electric kettle includes a flip-top lid located at the vent 7. The flip-top lid can rotate relative to the vent 7, allowing the vent 7 to switch between an open and closed state. In the open state, the vent 7 connects the water storage chamber 11 to the outside. During use, by rotating the flip-top lid at the vent 7, the vent 7 can be switched between open and closed states. When heating the water in the water storage chamber 11, rotating the flip-top opens the vent 7, allowing the water storage chamber 11 to connect with the outside. This allows gas inside the water storage chamber 11 to be released to the outside, maintaining stable gas pressure within the water storage chamber 11 without needing to remove the filter assembly 2 from the water storage chamber 11. When the water in the water storage chamber 11 is heated and the user needs to use it, rotating the flip-top closes the vent 7, preventing the water storage chamber 11 from connecting with the outside and effectively preventing water from flowing out of the vent 7.

[0084] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
