Description

Technical Field

[0001] This invention relates to the technical field of household appliances, and in particular to a detachable electric kettle. Background Technology

[0002] Common electric kettles on the market include integrated and detachable types. The detachable structure is more suitable for larger capacity kettles. Designing the water tank assembly and base as detachable allows for separate water filling of the water tank assembly. For example, utility model patent CN217723236U discloses a novel detachable electric kettle, which includes a kettle base and a kettle body that can be detachably mounted on the kettle base. The kettle body includes a plug-in mechanism, an inner liner, and an outer shell, with a handle on the outer shell for easy lifting and movement. In existing technology, the kettle base and kettle body are two separate components. When the entire electric kettle needs to be moved, both components must be moved separately, which is very inconvenient. Summary of the Invention

[0003] To address the shortcomings and deficiencies of existing technologies and to meet the usage needs of detachable electric kettles in both normal use and overall relocation scenarios, this invention provides a detachable electric kettle, comprising a detachable base and a water tank assembly. The base has an annular protrusion, and the water tank assembly includes an outer casing with an annular groove at its bottom. When the water tank assembly is placed on the base, the annular protrusion can be inserted into the annular groove. A ring-shaped fastening element is provided on one side wall of the annular protrusion. The outer casing has several latches at its bottom, arranged along the annular groove. Sidewall latch holes are provided on the side arms of the annular groove, allowing the latches to slide back and forth within these holes. The water tank assembly also includes a handle, an inner connecting block, and a drive shaft. A rack is provided at the upper end of the inner connecting block, and the latches are driven to the lower end. The latches slide back and forth when the inner connecting block moves up and down. Box shafts are provided on the left and right sides of the outer casing, each with a round shaft hole. The handle is bow-shaped with its ends... Each component is equipped with a handle shaft cover, through which the handle is rotatably sleeved onto the shaft of the housing. The side cover plate of the handle shaft cover has a square shaft hole, and the round shaft hole and the square shaft hole are arranged coaxially. The transmission shaft includes a round shaft section and square shaft sections and a transmission gear respectively connected to both ends of the round shaft section. The transmission shaft is movably inserted into the round shaft hole and the square shaft hole. When the transmission shaft moves inward to a first position, the round shaft section is inserted into the round shaft hole, the square shaft section is inserted into the square shaft hole, and the transmission gear is connected to the rack of the inner connecting block. At this time, the shaft rotates... The handle can move up and down with the inner connecting block via the drive shaft. The inner connecting block then drives the latch to slide through the side wall latch hole to engage with the latching groove to complete locking, or to retract the latch into the outer housing to complete unlocking. When the drive shaft moves outward to the second position, the round shaft section is simultaneously inserted into the round shaft hole and the square shaft hole. The square shaft section leaves the square shaft hole, and the drive gear separates from the rack of the inner connecting block. At this time, rotating the handle will not drive the inner connecting block, thus keeping the latch in its current state.

[0004] Furthermore, the housing shaft is also provided with a radially extending shaft locking hole, which connects to the circular shaft hole. A fan-shaped slot is provided on the outer side wall of the housing shaft, which connects to the shaft locking hole. A protruding locking block is provided on the circular shaft section. When the drive shaft switches from the second position to the first position, it can carry the locking block through the shaft locking hole into the fan-shaped slot. At this time, by rotating the drive shaft, it can carry the locking block to the other end of the fan-shaped slot, thereby keeping the drive shaft in the first position.

[0005] Furthermore, it also includes a shaft compression spring, which is disposed between the drive shaft and the housing shaft, and the shaft compression spring is capable of pushing the drive shaft to move inward.

[0006] Furthermore, it also includes a transmission shaft handle, which is connected to the outside of the square shaft section of the transmission shaft. By pushing or pulling the transmission shaft handle, the transmission shaft can be switched between a first position and a second position.

[0007] Furthermore, an inwardly extending shaft baffle is provided on the shaft handle, and a radially extending synchronous baffle is provided on the outer wall of the handle shaft cover. The synchronous baffle and the shaft baffle are detachably combined. When the handle rotates in the forward direction, the combination of the synchronous baffle and the shaft baffle can push the shaft handle and the transmission shaft to rotate in the forward direction. When the shaft handle rotates in the reverse direction, it can push the handle to rotate in the reverse direction together.

[0008] Furthermore, it also includes a drive ring, which is rotatably disposed at the bottom of the outer casing. The latch is movably disposed inside the drive ring. The latch includes a connecting end and a free end. The connecting end abuts against the inner wall of the drive ring, and the free end extends towards the center. A plug-in hole is provided on the drive ring. A plug-in arm is provided at the lower end of the inner connecting block. The plug-in arm is provided with a sloping push surface. When the plug-in arm is inserted downward into the plug-in hole, the sloping push surface of the plug-in arm can push the drive ring to rotate in the forward direction. A protrusion is also provided on the inner wall of the drive ring. When the drive ring rotates, the protrusion can push the latch, thereby allowing the free end of the latch to extend into the fastening groove.

[0009] Furthermore, it also includes a reset spring, which is disposed between the drive ring and the bottom of the outer housing. When the plug arm moves upward away from the plug hole, the drive ring rotates in the opposite direction to reset under the action of the reset spring. A latch spring is also provided between the latch and the outer housing, which can drive the latch to retract into the housing cavity.

[0010] Furthermore, a guide rail is provided at the bottom of the outer casing, and a groove matching the guide rail is provided at the bottom of the drive ring. The drive ring is slidably connected to the bottom of the outer casing through the cooperation of the groove and the guide rail.

[0011] Furthermore, the upper end of the inner connecting block is provided with a rack that matches the transmission gear.

[0012] Furthermore, it also includes a soft pad disposed between the base and the outer casing.

[0013] This invention has significant advantages and beneficial effects compared with the prior art.

[0014] First, by providing a fastening groove on the base and a movable latch on the water tank assembly, the water tank assembly and the base can be selectively fastened together or separated. In the fastened state, the base can be moved together by lifting the water tank assembly, which improves the convenience of moving the electric kettle.

[0015] Secondly, by rotating the handle, the inner connecting block can be moved up and down, and the inner connecting block can then drive the latch to slide to achieve locking and unlocking actions. That is, lifting the handle can lock and link with the base, reducing other unnecessary locking actions and improving the convenience of user use.

[0016] Third, a movable drive shaft is set as a connecting part. By pushing or pulling the drive shaft handle, the drive shaft can be easily switched to the first position or the second position, thereby allowing the drive gear to engage or disengage with the inner connecting block. This allows the user to freely choose to lock the water tank assembly with the base or operate it independently, giving the electric kettle two usage states. Attached Figure Description
