[0055] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0056] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Furthermore, terms such as "upper," "lower," "left," and "right" used in this disclosure are intended solely to describe the relative positions of the components of the disclosure as shown in the accompanying drawings.

[0057] Reference Figures 2 to 9 A locking device 11 includes a mounting seat 111, a locking rod 112, a driving portion 113, an elastic member 114 and a locking portion 115.

[0058] The locking rod 112 has a connecting portion 1121 axially mounted on the mounting base 111, and has a tail rod 1122 and a stop block 1123 disposed in front and behind the connecting portion 1121. The connecting portion 1121, tail rod 1122, and stop block 1123 are integrally connected. By pushing the tail rod 1122, the locking rod 112 can rotate around the connecting portion 1121, thereby changing the position of the stop block 1123.

[0059] The driving portion 113 is fixed to the mounting seat 111 , and includes a push rod 1131 abutting against the tail rod 1122 and a driving device 1132 driving the push rod 1131 to push the tail rod 1122 .

[0060] The elastic member 114 is disposed opposite to the push rod 1131, with one end of the elastic member 114 abutting against the mounting seat 111 and the opposite end abutting against the tail rod 1122. When the driving device 1132 drives the push rod 1131 to push the tail rod 1122, the elastic member 114 and the push rod 1131 jointly define a movement range of the tail rod 1122. Specifically, the elastic member 114 is a spring, preferably a compression spring, whose elastic force keeps the tail rod 1122 in contact with the push rod 1131. After the push rod 1131 is pushed out, it can be compressed by the tail rod 1122, thereby changing the position of the tail rod 1122.

[0061] The locking portion 115 is axially mounted on the mounting base 111 and is provided with a protrusion 1151 that engages with the stop block 1123. When the protrusion 1151 rotates to a predetermined position, the driving device 1132 receives an electrical signal and drives the push rod 1131 to push the tail rod 1122. The stop block 1123 correspondingly moves to the predetermined position, securing the protrusion 1151. The electrical signal here can be an electrical signal generated by turning on a manual power switch, an electrical signal generated by turning on an automatic power switch, or an electrical signal generated by a photoelectric sensor 12.

[0062] In addition, a cover plate 116 is coaxially disposed with the mounting seat 111 and fixedly connected to the locking portion. The cover plate 116 has a first latch 1161, and the mounting seat 111 has a second latch 1111. The ends of a vortex spring 117 or torsion spring are respectively secured to the first latch 1161 and the second latch 1111. When the cover plate 116 and the locking portion rotate and the protrusion 1151 is secured by the stop block 1123, the vortex spring 117 or torsion spring enters an energy storage state. If the push rod 1131 retracts at this time, the tail rod 1122 leaves the predetermined position under the push of the elastic member 114, and no longer secures the protrusion 1151, the cover plate 116 and the locking portion return to their initial positions under the action of the vortex spring 117 or torsion spring.

[0063] Based on the above structure, when the protrusion 1151 on the locking portion rotates to a predetermined position, the driving device 1132 receives an electrical signal and drives the push rod 1131 to push the tail rod 1122. The tail rod 1122 rotates to move the limit block 1123 to the predetermined position, fixing the protrusion 1151 and achieving locking. With this locking method, since the locking process is completed by the ejection of the push rod 1131 and the rotation of the tail rod 1122, the requirements for the matching accuracy are lower, and the situation of locking failure is less likely to occur.

[0064] The inventors have found in practice that in the existing locking mode of the latch and pin hole, if a power outage occurs in the locked state, the motor cannot be started, and the latch cannot be withdrawn from the pin hole, and the locked state remains. The user may manually twist it in an attempt to separate it, which may cause damage to the locking mechanism.

[0065] In the present invention, the driving device 1132 is an electromagnet. The electromagnet receives the electrical signal and drives the push rod 1131 to push the tail rod 1122. After receiving the electrical signal, the electromagnet is energized to generate a magnetic force, thereby pushing the push rod 1131 outward, thereby pushing the tail rod 1122 abutting against it, and then changing the position of the limit block 1123. If a power outage occurs during locking, the electromagnet loses power and can no longer push the push rod 1131 out. The tail rod 1122 can then be reset under the action of the elastic member 114, and the limit block 1123 leaves the predetermined position and separates from the protrusion 1151, and is no longer locked. Therefore, even if a power outage occurs in the locked state, the lock will not remain locked, preventing users from breaking the locking mechanism.

[0066] Reference Figures 2 to 9 A water adding column 1 includes a photoelectric sensor 12, a baffle 13, a circuit board 14, a mounting base 111, a locking rod 112, a driving part 113, an elastic member 114 and a locking part 115.

[0067] Among them, the mounting base 111 is provided with a water supply pipeline. Naturally, a valve is provided on the water supply pipeline to control the connection or closing of the water supply pipeline. This valve can be a manual valve or an electrically controlled valve, such as a solenoid valve. During specific use, it is electrically connected to the control main board in the base 2, and the opening and closing of the solenoid valve are controlled by the control main board.

[0068] The photoelectric sensor 12 has a groove 121. The photoelectric sensor 12 receives light signals, converts them into electrical signals, and transmits them to the circuit board 14. A baffle 13 extends through the groove 121 and has a notch 131. The baffle 13 moves within the groove 121. When the notch 131 aligns with the groove 121, the photoelectric sensor 12 receives the light signals. The circuit board 14 is electrically connected to the driver 1132 and the photoelectric sensor 12. The circuit board 14 receives the electrical signals transmitted by the photoelectric sensor 12 and transmits them to the driver 1132.

[0069] One side of the groove 121 emits light, while the other side receives light. If there is no obstruction in the groove 121, the photoelectric sensor 12 will always receive the light signal and convert it into an electrical signal. If it is blocked, no light will be received and no electrical signal will be generated. The baffle 13 can block the light emitted from one side of the groove 121 of the photoelectric sensor 12, and it remains blocked when it moves. At this time, there is no electrical signal and the drive device 1132 does not operate. Only when the gap 131 is moved to the light-emitting position can light pass through the gap 131 to the other side, be received, and generate an electrical signal. The electrical signal is received by the circuit board 14 and transmitted to the drive device 1132, which then controls the drive device 1132 to operate. That is, through the cooperation of the photoelectric sensor 12, the baffle 13 and the circuit board 14, the operation of the drive device 1132 can be controlled.

[0070] The locking rod 112 has a connecting portion 1121 axially mounted on the mounting base 111, and has a tail rod 1122 and a stop block 1123 respectively positioned in front and behind the connecting portion 1121. The connecting portion 1121, tail rod 1122, and stop block 1123 are integrally connected. By pushing the tail rod 1122, the locking rod 112 can rotate around the connecting portion 1121, thereby changing the position of the stop block 1123.

[0071] The driving portion 113 is fixed to the mounting seat 111 and is provided with a push rod 1131 abutting against the tail rod 1122 and the driving device 1132 driving the push rod 1131 to push the tail rod 1122 .

[0072] The elastic member 114 is disposed opposite to the push rod 1131, with one end of the elastic member 114 abutting against the mounting seat 111 and the opposite end abutting against the tail rod 1122. When the driving device 1132 drives the push rod 1131 to push the tail rod 1122, the elastic member 114 and the push rod 1131 jointly define a movement range of the tail rod 1122. Specifically, the elastic member 114 is a spring, preferably a compression spring, whose elastic force keeps the tail rod 1122 in contact with the push rod 1131. After the push rod 1131 is pushed out, it can be compressed by the tail rod 1122, thereby changing the position of the tail rod 1122.

[0073] The locking portion 115 is pivotally mounted on the mounting base 111 and includes a protrusion 1151 that engages with the stop block 1123. When the protrusion 1151 rotates to a predetermined position, the driving device 1132 receives the electrical signal and drives the push rod 1131 to push the tail rod 1122. The stop block 1123 correspondingly moves to the predetermined position, securing the protrusion 1151. Specifically, when the protrusion 1151 rotates to the predetermined position, the notch 131 on the baffle 13 corresponds to the groove 121. The photoelectric sensor 12 receives the light signal and generates an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132, which then actuates to push the push rod 1131 out, causing the stop block 1123 to secure the protrusion 1151.

[0074] Based on the above structure, on the water filling column 1, when the locking part 115 rotates and the protrusion 1151 rotates to the predetermined position, the notch 131 on the baffle 13 corresponds exactly to the position of the groove 121, the photoelectric sensor 12 receives light and converts it into an electrical signal, the circuit board 14 transmits the electrical signal to the driving device 1132, and the driving device 1132 pushes the tail rod 1122 so that the limit block 1123 fixes the protrusion 1151 at the predetermined position.

[0075] Specifically, a water-adding arm 16 is pivotally connected to the mounting base 111. One end of the water-adding arm 16 is a rotating connection end 161 pivotally connected to the mounting base 111, and the other end is a water-injection end 162 equipped with a water inlet. The water-injection pipeline extends to the water-adding arm 16 and communicates with the water inlet. The water-adding arm 16 has a water-adding state and an initial state. Specifically, the water-adding arm 16 rotates about the rotating connection end 161, thereby changing the position of the water inlet, allowing the water inlet to switch between the water-adding state and the initial state.

[0076] The locking portion 115 is fixed to the rotating connection end 161 and can rotate together with the rotating connection end 161. The predetermined position of the protrusion 1151 of the locking portion 115 corresponds to the water adding state position, that is, when the water adding rotating arm 16 rotates to the water adding state position, the protrusion 1151 also moves to the predetermined position. At this time, the photoelectric sensor 12 receives light and converts it into an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132. The driving device 1132 pushes the tail rod 1122 to make the limit block 1123 fix the protrusion 1151 in the predetermined position, that is, the water adding rotating arm 16 is fixed in the water adding state position, so that the water adding rotating arm 16 can add water.

[0077] Furthermore, the water filling column 1 includes a cover plate 116 coaxially mounted with the mounting base 111. The cover plate 116 has a first latch 1161, while the mounting base 111 has a second latch 1111. Similarly, the cover plate 116 is fixed to the rotating connection end 161 and can rotate with the rotating connection end 161. Preferably, the water filling column 1 also includes a vortex spring 117 or torsion spring, the ends of which are respectively secured to the first latch 1161 and the second latch 1111. When the water-adding rotating arm 16 drives the cover plate 116 and the locking part 115 to rotate to the water-adding state position, the vortex spring 117 or the torsion spring stores energy. When the top rod 1131 of the driving device 1132 retracts, the elastic member 114 pushes the tail rod 1122 away, so that the limit block 1123 is no longer in the predetermined position and the protrusion 1151 is no longer fixed. Then the vortex spring 117 or the torsion spring moves the locking part 115 and the water-adding rotating arm 16 away together and returns to the initial position.

[0078] Preferably, the driving device 1132 is an electromagnet, which is energized and works after receiving an electrical signal, so that the top rod 1131 is extended and the tail rod 1122 is pushed, thereby locking the protrusion 1151 in the predetermined position (i.e., locking the water filling arm 16 in the water filling state). If an unexpected power outage occurs at this time, the electromagnet will be out of power and unable to maintain the extended state of the top rod 1131. The elastic member 114 pushes the tail rod 1122, so that the limit block 1123 leaves the predetermined position, the protrusion 1151 is unlocked, and the water filling arm 16 returns to the initial state under the action of the vortex spring 117 or the torsion spring.

[0079] Preferably, the water-adding column 1 further comprises a damping reducer 15, the damping reducer 15 being fixed on the mounting base 111, the damping reducer 15 being provided with a damping connecting shaft 151 and a transmission gear 152 fixedly connected to the damping connecting shaft 151; the cover plate 116 being provided with driving teeth 1162, the driving teeth 1162 being engaged with the transmission gear 152. The damping connecting shaft 151 of the damping reducer 15 is transmission-connected to the cover plate 116 via a gear, which can generate resistance to the rotation of the cover plate 116, whether during the process of the cover plate 116 rotating from the initial state position to the water-adding state position or during the process of rotating from the water-adding state position to the initial state position, thereby preventing the water-adding rotating arm 16 from rotating too fast and damaging various components.

[0080] Reference Figures 1 to 9 , an electric teapot 100 includes an electric kettle, a water adding column 1 and a base 2.

[0081] Among them, the electric kettle is used to receive water.

[0082] The water adding column 1 is used to add water to the electric kettle, and has a built-in water adding pipeline with a control valve. The water adding column 1 includes a mounting seat 111, a locking rod 112, a driving part 113, an elastic member 114, and a locking part 115.

[0083] The locking rod 112 is provided with the connecting portion 1121 axially arranged on the mounting seat 111 , and a tail rod 1122 and a limiting block 1123 are respectively provided in front and behind the connecting portion 1121 .

[0084] The driving portion 113 is fixed to the mounting seat 111 and includes a push rod 1131 that abuts the tail rod 1122 and a driving device 1132 that drives the push rod 1131 to push the tail rod 1122. The elastic member 114 is disposed opposite the push rod 1131, with one end abutting the mounting seat 111 and the opposite end abutting the tail rod 1122. When the driving device 1132 drives the push rod 1131 to push the tail rod 1122, the elastic member 114 and the push rod 1131 jointly define the movement range of the tail rod 1122.

[0085] The locking portion 115 is axially arranged on the mounting seat 111 and is provided with a protrusion 1151 that cooperates with the limit block 1123; when the protrusion 1151 rotates to a predetermined position, the driving device 1132 receives an electrical signal and drives the top rod 1131 to push the tail rod 1122, and the limit block 1123 moves to the predetermined position accordingly to fix the protrusion 1151.

[0086] The base 2 is provided with a control mainboard therein, and the control mainboard controls the water adding column 1 to inject water into the electric kettle.

[0087] Based on the above structure, when the locking part 115 on the water filling column 1 drives the protrusion 1151 to rotate to a predetermined position, the photoelectric sensor receives the light signal and converts it into an electrical signal, which is transmitted to the driving device 1132 through the circuit board 14. The driving device 1132 drives the top rod 1131 to push the tail rod 1122, so that the limit block 1123 fixes the protrusion 1151.

[0088] In a specific embodiment, the water-adding column 1 has a water-adding rotating arm 16, which is axially connected to the mounting seat 111. One end of the water-adding rotating arm 16 is a rotating connection end 161 axially connected to the mounting seat 111, and the other end is a water injection end 162 provided with a water injection port. The water-adding pipeline extends to the water-adding rotating arm 16 and is connected to the water injection port. The water-adding rotating arm 16 has a water-adding state position and an initial state position. That is, the water-adding rotating arm 16 rotates around the rotating connection end 161, thereby changing the position of the water injection port, so that the water injection port can move and switch between the water-adding state and the initial state position. The locking portion 115 is fixed to the rotating connection end 161 and can rotate with the rotating connection end 161. The predetermined position of the protrusion 1151 of the locking portion 115 corresponds to the water adding state position, that is, when the water adding rotating arm 16 rotates to the water adding state position, the protrusion 1151 also moves to the predetermined position. At this time, the photoelectric sensor 12 receives light and converts it into an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132. The driving device 1132 pushes the tail rod 1122 to make the limit block 1123 fix the protrusion 1151 at the predetermined position, that is, the water adding rotating arm 16 is fixed in the water adding state position, and then the water adding column 1 is controlled by the control main board to inject water.

[0089] Example 1:

[0090] Reference Figures 2 to 7 A water adding column 1 includes a photoelectric sensor 12, a baffle 13, a circuit board 14, a mounting base 111, a locking rod 112, a driving part 113, an elastic member 114 and a locking part 115.

[0091] Among them, the mounting base 111 is provided with a water supply pipeline. Naturally, a valve is provided on the water supply pipeline to control the connection or closing of the water supply pipeline. This valve can be a manual valve or an electrically controlled valve, such as a solenoid valve. During specific use, it is electrically connected to the control main board in the base 2, and the opening and closing of the solenoid valve are controlled by the control main board.

[0092] A water-adding arm 16 is pivotally connected to the mounting base 111. One end of the arm 16 is a pivotally connected end 161 pivotally connected to the mounting base 111, and the other end is a water-injection end 162 equipped with a water inlet. The water-injection pipeline extends through the arm 16 and communicates with the inlet. The arm 16 has a water-adding position and an initial position. Specifically, the arm 16 rotates about the pivotally connected end 161, thereby changing the position of the water inlet, allowing the inlet to switch between the water-adding and initial positions.

[0093] Among them, reference Figure 4 、 5 and Figure 7The photoelectric sensor 12 is provided with a groove 121. The photoelectric sensor 12 receives the light signal and converts the light signal into an electrical signal and transmits it to the circuit board 14. The baffle 13 passes through the groove 121. The baffle 13 is provided with a notch 131. The baffle 13 moves in the groove 121. When the notch 131 corresponds to the groove 121, the photoelectric sensor 12 receives the light signal. The circuit board 14 is electrically connected to the driving device 1132 and the photoelectric sensor 12. The circuit board 14 receives the electrical signal transmitted by the photoelectric sensor 12 and transmits the electrical signal to the driving device 1132. Of the photoelectric sensor 12 and the baffle 13, one is mounted on the water-adding rotating arm 16, and the other is mounted on the mounting seat 111. In this way, when the water-adding rotating arm 16 rotates, the baffle 13 can be moved in the groove 121.

[0094] One side of the groove 121 emits light, while the other side receives light. If there is no obstruction in the groove 121, the photoelectric sensor 12 will always receive the light signal and convert it into an electrical signal. If it is blocked, no light will be received and no electrical signal will be generated. The baffle 13 can block the light emitted from one side of the groove 121 of the photoelectric sensor 12, and it remains blocked when it moves. At this time, there is no electrical signal and the drive device 1132 does not operate. Only when the gap 131 is moved to the light-emitting position can light pass through the gap 131 to the other side, be received, and generate an electrical signal. The electrical signal is received by the circuit board 14 and transmitted to the drive device 1132, which then controls the drive device 1132 to operate. That is, through the cooperation of the photoelectric sensor 12, the baffle 13 and the circuit board 14, the operation of the drive device 1132 can be controlled.

[0095] The locking rod 112 has a connecting portion 1121 axially mounted on the mounting base 111, and has a tail rod 1122 and a stop block 1123 respectively positioned in front and behind the connecting portion 1121. The connecting portion 1121, tail rod 1122, and stop block 1123 are integrally connected. By pushing the tail rod 1122, the locking rod 112 can rotate around the connecting portion 1121, thereby changing the position of the stop block 1123.

[0096] The driving portion 113 is fixed to the mounting seat 111, and is provided with a top rod 1131 that abuts against the tail rod 1122 and a driving device 1132 that drives the top rod 1131 to push the tail rod 1122. In this embodiment, the driving device 1132 is an electromagnet. The electromagnet is energized after receiving an electrical signal, so that the top rod 1131 extends and pushes the tail rod 1122, thereby locking the protrusion 1151 in a predetermined position (i.e., locking the water-filling arm 16 in the water-filling state). If an unexpected power outage occurs at this time, the electromagnet will be out of power and unable to maintain the extended state of the top rod 1131. The elastic member 114 pushes the tail rod 1122, causing the limit block 1123 to leave the predetermined position, and the protrusion 1151 is unlocked. The water-filling arm 16 returns to its initial state under the action of the vortex spring 117 or the torsion spring. In this embodiment, when viewed from above, Figure 4 and Figure 5 As shown, the electromagnet is arranged on the right side of the locking rod 112, and the electromagnet drives the ejector rod 1131 to be pushed out from right to left. Figure 8 and Figure 9 As shown, in a top view, the electromagnet is arranged on the left side of the locking rod 112, and the electromagnet drives the ejector rod 1131 to be pushed out from left to right.

[0097] The elastic member 114 is disposed opposite the push rod 1131. One end of the elastic member 114 abuts the mounting seat 111, and the opposite end abuts the tail rod 1122. When the driving device 1132 drives the push rod 1131 to push the tail rod 1122, the elastic member 114 and the push rod 1131 jointly define the movement range of the tail rod 1122. In this embodiment, the elastic member 114 is a compression spring, the elastic force of which maintains the tail rod 1122 in contact with the push rod 1131. After the push rod 1131 is pushed out, the push rod 1131 can be compressed by the tail rod 1122, thereby changing the position of the tail rod 1122.

[0098] The locking portion 115 is pivotally mounted on the mounting base 111 and includes a protrusion 1151 that engages with the stop block 1123. When the protrusion 1151 rotates to a predetermined position, the driving device 1132 receives the electrical signal and drives the push rod 1131 to push the tail rod 1122. The stop block 1123 correspondingly moves to the predetermined position, securing the protrusion 1151. Specifically, when the protrusion 1151 rotates to the predetermined position, the notch 131 on the baffle 13 corresponds to the groove 121. The photoelectric sensor 12 receives the light signal and generates an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132, which then actuates to push the push rod 1131 out, causing the stop block 1123 to secure the protrusion 1151.

[0099] In this embodiment, the locking portion 115 is fixed on the rotating connection end 161 and can rotate together with the rotating connection end 161. The predetermined position of the protrusion 1151 of the locking portion 115 corresponds to the water adding state position, that is, when the water adding rotating arm 16 rotates to the water adding state position, the protrusion 1151 also moves to the predetermined position, at this time the photoelectric sensor 12 receives light and converts it into an electrical signal, the circuit board 14 transmits the electrical signal to the driving device 1132, and the driving device 1132 pushes the tail rod 1122 to make the limit block 1123 fix the protrusion 1151 at the predetermined position, that is, the water adding rotating arm 16 is fixed in the water adding state position, so that the water adding rotating arm 16 can add water.

[0100] The water filling column 1 also includes a cover plate 116 coaxially mounted with the mounting base 111. The cover plate 116 is fixedly connected to the locking portion 115. The cover plate 116 has a first latch 1161, and the mounting base 111 has a second latch 1111. Similarly, the cover plate 116 is fixed to the rotating connection end 161 and can rotate with the rotating connection end 161. Preferably, the water filling column 1 also includes a vortex spring 117 or torsion spring, the two ends of which are respectively fixed to the first latch 1161 and the second latch 1111. When the water-adding rotating arm 16 drives the cover plate 116 and the locking part 115 to rotate to the water-adding state position, the vortex spring 117 or the torsion spring stores energy. When the top rod 1131 of the driving device 1132 retracts, the elastic member 114 pushes the tail rod 1122 away, so that the limit block 1123 is no longer in the predetermined position and the protrusion 1151 is no longer fixed. Then the vortex spring 117 or the torsion spring restores and moves the locking part 115 and the water-adding rotating arm 16 away together and returns to the initial position.

[0101] The water-adding column 1 also includes a damping reducer 15, which is fixed to the mounting base 111. The damping reducer 15 is provided with a damping connecting shaft 151 and a transmission gear 152 fixedly connected to the damping connecting shaft 151; the cover plate 116 is provided with driving teeth 1162, and the driving teeth 1162 are engaged with the transmission gear 152. The damping connecting shaft 151 of the damping reducer 15 is connected to the cover plate 116 through a gear, which can generate resistance to the rotation of the cover plate 116, whether it is in the process of rotating the cover plate 116 from the initial state position to the water-adding state position or in the process of rotating from the water-adding state position to the initial state position, thereby preventing the water-adding rotating arm 16 from rotating too fast and damaging various components.

[0102] Based on the above structure, when the user pushes the water adding arm 16 from the initial state position to the water adding state position, the locking part rotates to the predetermined position with the water adding arm 16, and the notch 131 on the baffle 13 corresponds exactly to the position of the groove 121. The photoelectric sensor 12 receives light and converts it into an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132. The driving device 1132 pushes the tail rod 1122 so that the limit block 1123 fixes the protrusion 1151 at the predetermined position, which also fixes the water adding arm 16 in the water adding state position.

[0103] The water adding column 1 is used in an electric kettle 100 when it is specifically implemented. The electric kettle 100 has a base 2 and an electric kettle 3. The specific working process of use is as follows:

[0104] 1) Initial state: The water filling arm 16 is in the initial state position. At this time, the vortex spring 117 or the torsion spring is in a natural state, the baffle 13 blocks the light of the photoelectric sensor 12, the driving device 1132 is not working, and the protrusion 1151 and the limit block 1123 are not in the predetermined position;

[0105] 2) Pushing the water filling arm 16: The user pushes the water filling arm 16 to rotate in the direction of the water filling state, which is clockwise in this embodiment. At this time, the vortex spring 117 or the torsion spring is compressed, the baffle 13 blocks the light from the photoelectric sensor 12, the driving device 1132 does not work, the protrusion 1151 moves to the predetermined position as the water filling arm 16 rotates, and the limit block 1123 remains stationary;

[0106] 3) Water Adding State: The water adding arm 16 rotates to the water adding state position, which is 71 degrees clockwise relative to the initial state position. Of course, this angle can be set as needed. The protrusion 1151 is now in the predetermined position. At this time, the vortex spring 117 or torsion spring is compressed, the notch 131 is located in the groove 121, the photoelectric sensor 12 receives light and converts it into an electrical signal. The circuit board 14 transmits the electrical signal to the drive device 1132, pushing the lock tail rod 1122, compressing the elastic member 114, and the limit block 1123 moves to the predetermined position to fix the gas, locking the water adding arm 16 in the water adding state position. At this time, the electric kettle is on the base, just below the water inlet. The water adding pipeline can be controlled by the control motherboard of the base 2 to add water.

[0107] 4) Reset: After water addition is completed, the top rod 1131 of the driving device 1132 retracts, the tail rod 1122 is reset under the action of the elastic member 114, the limit block 1123 moves out of the predetermined position, and the water addition arm 16 rotates toward the initial position under the action of the vortex spring 117 or the torsion spring, driving the baffle 13 to move so that the notch 131 moves out of the groove 121, and the baffle 13 blocks the light of the photoelectric sensor 12 again;

[0108] 5) Return to the initial state: the water adding arm 16 is in the initial state, at which time the vortex spring 117 or the torsion spring is in a natural state, the baffle 13 blocks the light of the photoelectric sensor 12, and the driving device 1132 is not working.

[0109] In the water adding state, if a power outage occurs, the driving device 1132 (electromagnet) will not be energized and will not maintain the extension of the top rod 1131, and the limit block 1123 cannot be maintained in the predetermined position, and the protrusion 1151 can no longer be fixed. The water adding arm 16 will rotate toward the initial state position under the action of the vortex spring 117 or the torsion spring until it returns to the initial state position.

[0110] Example 2:

[0111] Reference Figures 1 to 9 , an electric teapot 100 includes an electric kettle, a water adding column 1 and a base 2.

[0112] Among them, the electric kettle is used to receive water.

[0113] The water adding column 1 is used to add water to the electric kettle, and has a built-in water adding pipeline with a control valve. The water adding column 1 includes a mounting seat 111, a locking rod 112, a driving part 113, an elastic member 114, and a locking part 115.

[0114] The locking rod 112 is provided with the connecting portion 1121 axially arranged on the mounting seat 111 , and a tail rod 1122 and a limiting block 1123 are respectively provided in front and behind the connecting portion 1121 .

[0115] The driving portion 113 is fixed to the mounting seat 111 and includes a push rod 1131 that abuts the tail rod 1122 and a driving device 1132 that drives the push rod 1131 to push the tail rod 1122. The elastic member 114 is disposed opposite the push rod 1131, with one end abutting the mounting seat 111 and the opposite end abutting the tail rod 1122. When the driving device 1132 drives the push rod 1131 to push the tail rod 1122, the elastic member 114 and the push rod 1131 jointly define the movement range of the tail rod 1122.

[0116] The locking portion 115 is axially arranged on the mounting seat 111 and is provided with a protrusion 1151 that cooperates with the limit block 1123; when the protrusion 1151 rotates to a predetermined position, the driving device 1132 receives an electrical signal and drives the top rod 1131 to push the tail rod 1122, and the limit block 1123 moves to the predetermined position accordingly to fix the protrusion 1151.

[0117] The base 2 is provided with a control mainboard therein, and the control mainboard controls the water adding column 1 to inject water into the electric kettle.

[0118] In this embodiment, the various components of the water adding column 1 can refer to the description of the water adding column 1 in Example 1, and will not be repeated here.

[0119] Referring to Example 1, in this embodiment, the water adding column 1 also has a water adding rotating arm 16, and the water adding rotating arm 16 is axially connected to the mounting seat 111. One end of the water adding rotating arm 16 is a rotating connection end 161 axially connected to the mounting seat 111, and the other end is a water injection end 162 provided with a water injection port. The water adding pipeline extends to the water adding rotating arm 16 and is connected to the water injection port. The water adding rotating arm 16 has a water adding state position and an initial state position. That is, the water adding rotating arm 16 rotates around the rotating connection end 161 as the center, thereby changing the position of the water injection port, so that the water injection port can move and switch between the water adding state and the initial state position. The locking portion 115 is fixed on the rotating connection end 161 and can rotate together with the rotating connection end 161. The predetermined position of the protrusion 1151 of the locking portion 115 corresponds to the water adding state position, that is, when the water adding rotating arm 16 rotates to the water adding state position, the protrusion 1151 also moves to the predetermined position. At this time, the photoelectric sensor 12 receives light and converts it into an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132. The driving device 1132 pushes the tail rod 1122 to make the limit block 1123 fix the protrusion 1151 at the predetermined position, that is, the water adding rotating arm 16 is fixed in the water adding state position, and then the water adding column 1 is controlled by the control main board to inject water.

[0120] Based on the above structure, when the user pushes the water adding arm 16 from the initial state position to the water adding state position, the locking part rotates to the predetermined position with the water adding arm 16, and the notch 131 on the baffle 13 corresponds exactly to the position of the groove 121. The photoelectric sensor 12 receives light and converts it into an electrical signal. The circuit board 14 transmits the electrical signal to the driving device 1132. The driving device 1132 pushes the tail rod 1122 so that the limit block 1123 fixes the protrusion 1151 at the predetermined position, that is, the water adding arm 16 is also fixed in the water adding state position, so that water can be added.

[0121] Other contents of the water adding column and the electric kettle kit described in the present invention can be found in the prior art and will not be described in detail here.

[0122] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
