Specific embodiments

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention and their beneficial effects will be further described in detail below with reference to the accompanying drawings.

[0031] The water extraction device of the automatic water pumping kettle is an important component of the conduit passing through the appliance coupler in the middle, and the liquid is directly diverted from the bottom of the kettle to the spout. This device has an anti-backflow mechanism. When the inner container is lifted, the inner container can be separated from the base water extraction component, and the liquid in the inner container will not leak from the bottom, which is convenient for cleaning the kettle body separately or directly receiving water.

[0032] As Figure 1 shown, an embodiment of the present invention provides an appliance coupler water extraction device for an inner container detachable liquid heater, which enables the liquid to be directly diverted from the bottom of the kettle to important components such as the spout, and the water is diverted from the kettle.

[0033] The appliance coupler water extraction device specifically includes: a water inlet pipe assembly and a water extraction pipe assembly. The water inlet pipe assembly is internally connected to the inner container 110, and the water extraction pipe assembly is installed on the base body; when the inner container 110 is placed in the base body, the water inlet pipe assembly is connected to the water extraction pipe assembly to form a liquid flow path starting from the inner container 110, passing through the water inlet pipe assembly, and flowing to the water extraction pipe assembly. Thus, the liquid in the inner container 110 can flow out through the liquid flow path.

[0034] As Figure 2 and Figure 3As shown, another embodiment of the present invention provides an appliance coupler, which includes an appliance coupler pumping device, a connector 1, and an appliance input socket 2. Specifically, the bottom of the inner tank 110 is recessed inwardly to form a water leakage cap 111, and a plurality of first water leakage holes 112 are provided on the water leakage cap 111. The appliance coupler pumping device includes a connector 1, an appliance input socket 2, a water inlet pipe assembly, and a water extraction pipe assembly. The connector 1 is fixedly connected to the inner tank 110. Specifically, the connector 1 is fixed to the inner tank 110 by a plurality of bolts. A round hole is provided at the central position of the connector 1, and the water inlet pipe assembly is arranged in the round hole of the connector 1. A water inlet channel is formed in the water inlet pipe assembly. One end of the water inlet pipe assembly close to the inner tank 110 extends into the recess of the water leakage cap 111 and communicates with the inside of the inner tank 110. Therefore, the liquid in the inner tank 110 can flow into the water inlet channel of the water inlet pipe assembly. A round hole penetrating the appliance input socket 2 is provided at the central position of the appliance input socket 2, and the water extraction pipe assembly is arranged in the round hole of the appliance input socket 2 and passes through the round hole. The appliance input socket 2 is in plug-in fit with the connector 1. That is, when the kettle in the inner tank separable liquid heater is placed on the connector 1, the appliance input socket 2 is plugged into the connector 1. When the inner tank 110 is placed in the base body, one end of the water extraction pipe assembly is inserted into the water inlet channel and sealedly connected to the second end of the water inlet pipe assembly, so that the water path is connected. In the pumping state, the liquid in the inner tank sequentially flows out through the water inlet channel and the water extraction pipe assembly. Compared with the traditional kettle that requires the user to lift the kettle and tilt it to pour the water into an external water container from the spout, in the technical solution of the present invention, after the heater finishes heating the water in the inner tank, the user does not need to lift the kettle, and the water in the kettle inner tank can flow out through the water inlet pipe assembly and the water extraction pipe assembly, reducing the situation of spilling, avoiding scalding children, the elderly, and users with physical disabilities, and having high safety. When the kettle is taken out, the appliance input socket 2 is separated from the connector 1, and the water path is disconnected.

[0035] By providing the water leakage cap 111 and a plurality of first water leakage holes 112, it is possible to prevent large-scale water scale or solid particles at the bottom of the inner tank 110 from flowing into the inside of the water inlet pipe 5 or the water extraction pipe 7 along with the liquid, causing blockage.

[0036] Optionally, the multiple first water leakage holes 112 on the water leakage cap 111 are densely arranged so that the water leakage cap 111 is in a grid shape.

[0037] Such as Figure 1 and Figure 3As shown, further, the water inlet pipe assembly specifically includes: a water inlet pipe 5, a first sealing sleeve 6, a water sealing slider 3, and a first spring 11. Among them, one end of the water inlet pipe 5 facing the inner tank 110 is inserted into the recess of the water leakage cap 111 to communicate with the inside of the inner tank; the first sealing sleeve 6 is embedded in the water inlet pipe 5, and the first sealing sleeve 6 is located at the end of the water inlet pipe 5 away from the inner tank 110. The first sealing sleeve 6 is provided with a through hole 61 penetrating the first sealing sleeve 6; the water sealing slider 3 is slidably arranged in the water inlet pipe 5. Specifically, the water sealing slider 3 is located at the end of the water inlet pipe 5 close to the inner tank 110. As Figure 8 and Figure 10 shown, the water sealing slider 3 includes a tubular sliding portion 31 and a columnar sealing portion 32 connected to the sliding portion 31. The outer wall of the sliding portion 31 contacts the inner wall of the water inlet pipe 5, so that the sliding portion 31 can slide along the axial direction of the water inlet pipe 5 within the inner wall of the water inlet pipe 5. A plurality of second water leakage holes 311 are provided on the sliding portion 31, and the second water leakage holes 311 respectively communicate the internal spaces of the water inlet pipe 5 on both sides of the water sealing slider 3. The first spring 11 is arranged in the sliding portion 31. One end of the first spring 11 abuts against the water leakage cap 111, and the other end abuts against the sealing portion 32. When the appliance input socket 2 is separated from the connector 1, as Figure 4 shown, the first spring 11 pushes the sealing portion 32 into the through hole 61 to block the through hole 61, forming a sealed partition, thereby preventing the water in the inner tank from flowing out through the water inlet pipe 5 when the appliance input socket 2 is separated from the connector 1, causing leakage of the liquid in the inner tank; when the appliance input socket 2 is plugged into the connector 1, one end of the water extraction pipe assembly penetrates the through hole 61 and abuts against the sealing portion 32, so that the first spring 11 is compressed, and the sealing portion 32 is separated from the through hole 61 to form a water outlet gap. The inside of the inner tank is communicated with the water extraction pipe assembly through the water inlet pipe assembly, and the liquid in the inner tank can flow out through the water inlet pipe 5 and the water extraction pipe assembly.

[0038] Among them, the sealing portion 32 is made of rubber material, so it has the characteristics of sealing, anti-slip and elasticity. When the sealing portion 32 is inserted into the through hole 61, the sealing portion 32 is squeezed by the inner wall of the through hole 61, generating a small amount of deformation, so that the inner wall of the through hole 61 is tightly attached to the sealing portion 32, forming a sealed partition to better block the through hole 61.

[0039] Further, the water extraction pipe assembly includes: a water extraction pipe 7, a second spring 8, as Figure 3 and Figure 6As shown in the figure, a plurality of third water leakage holes 71 are provided on the pipe wall of the water extraction pipe 7. An annular step structure is formed by the outer wall of the water extraction pipe 7 protruding radially along the water extraction pipe 7. The step structure includes a first step 72 and a second step 73. The first step 72 is located on the side closer to the inner tank 110 relative to the second step 73. The second spring 8 is sleeved on the water extraction pipe 7. The second spring 8 is located on the side of the step structure away from the inner tank 110. One end of the second spring 8 abuts against the side of the second step 73 away from the inner tank 110, and the other end abuts against the side of the appliance input socket 2 facing the inner tank 110. When the connector 1 is inserted into the appliance input socket 2, the second spring 8 provides a supporting force towards the inner tank 110 to the second step 73 of the water extraction pipe 7, so that the second spring 8 pushes the water extraction pipe 7 through the through hole 61 to abut against the sealing portion 32, ensuring the tightness and stability of the connection between the water extraction pipe 7 and the first sealing sleeve 6. The third water leakage holes 71 are located in the water inlet pipe 5 between the first sealing sleeve 6 and the sealing portion 32, so that the water inlet pipe 5 is communicated with the water extraction pipe 7, and the water in the inner tank sequentially flows into the water extraction pipe 7 through the first water leakage holes 112, the water inlet pipe 5, the second water leakage holes 311, and the third water leakage holes 71, thereby leading out the water in the inner tank.

[0040] There are multiple third water leakage holes 71, which are located on the side wall of the water extraction pipe 7 and are distributed in a circumferential array centered on the axis of the water extraction pipe 7.

[0041] As Figure 5 shown, further, a limiting portion 51 in the form of an annular protrusion is provided on the inner wall of the water inlet pipe 5 along the radial direction of the water inlet pipe 5. The first sealing sleeve 6 is located on the side of the limiting portion 51 away from the inner tank 110, and the sealing sleeve abuts against the limiting portion 51. The water sealing slider 3 is located on the side of the limiting portion 51 close to the inner tank 110. Among them, when the appliance input socket 2 is separated from the connector 1, the first spring 11 pushes the sliding portion 31 to abut against the limiting portion 51. The limiting portion 51 is used to limit the positions of the water sealing slider 3 and the first sealing sleeve 6 in the water inlet pipe 5 to prevent the water sealing slider 3 from sliding out of the water inlet pipe 5.

[0042] Further, as Figure 3 and Figure 5 shown, a supporting portion 52 in the form of an annular protrusion is formed on the outer wall of the water inlet pipe 5 along the radial direction of the water inlet pipe 5. Along the axial direction of the water inlet pipe 5, both sides of the supporting portion 52 abut against the inner tank 110 and the connector 1 respectively, thereby fixing the water inlet pipe 5. As Figure 9 shown, an annular recessed portion 521 is provided on the side of the supporting portion 52 facing the inner tank 110 sleeve. The water inlet pipe assembly further includes an annular second sealing sleeve 4. The second sealing sleeve 4 is provided in the recessed portion 521, and one end of the second sealing sleeve 4 abuts against the inner tank 110 and the other end abuts against the supporting portion 52, realizing the sealed connection between the water inlet pipe 5 and the inner tank 110 and preventing liquid from leaking between the inner tank 110 and the water inlet pipe 5.

[0043] As Figure 7As shown, further, a first chamfer 611 is provided at one end of the through hole 61 close to the inner container 110; as Figure 8 shown, a first conical surface 322 is provided at one end of the sealing portion 32 away from the inner container 110. The first conical surface 322 is annular, and the diameter of the first conical surface 322 is adapted to the inner diameter of the first chamfer 611. When the appliance input socket 2 is separated from the connector 1, the first conical surface 322 is in sealing fit with the conical surface of the first chamfer 611. Through the sealing fit between the first conical surface 322 and the conical surface of the first chamfer 611, on the one hand, the contact area of the sealing surface is increased. On the other hand, since the water sealing slider 3 and the through hole 61 are in a state transition between contact and separation, through the cooperation between the first conical surface 322 and the conical surface of the first chamfer 611, the water sealing slider 3 and the through hole 61 can be better aligned, and the through hole 61 is blocked, thereby improving the sealing performance.

[0044] Conical surfaces are provided on both sides of the limiting portion 51 opposite to the sliding portion 31. When the appliance input socket 2 is separated from the connector 1, the conical surface of the limiting portion 51 is in contact with the conical surface of the sliding portion 31.

[0045] Further, a second chamfer 612 is provided at one end of the through hole 61 away from the inner container 110; a second conical surface 721 is provided at one end of the first platform 72 close to the inner container 110. When the appliance input socket 2 is inserted into the connector 1, the second conical surface 721 is in abutting seal with the conical surface of the second chamfer 612. Through the sealing fit between the second conical surface 721 and the conical surface of the second chamfer 612, the contact area of the sealing surface is increased. On the other hand, since the water extraction pipe 7 and the through hole 61 are in a state transition between contact and separation, through the cooperation between the second conical surface 721 and the conical surface of the second chamfer 612, the water extraction pipe 7 and the through hole 61 can be better aligned, so that the water extraction pipe 7 can be smoothly inserted into the through hole 61.

[0046] Further, as Figure 1 and Figure 3 shown, the water extraction pipe assembly further includes a caliper 9. On the outer wall of the water extraction pipe 7, an annular groove 10 is provided along the radial direction of the water extraction pipe 7. The caliper 9 is stuck in the annular groove 10, so that the caliper 9 is detachably sleeved on the water extraction pipe 7; when the appliance input socket 2 is separated from the connector 1, the second spring 8 pushes the water extraction pipe 7 to move towards the side of the water inlet pipe 5, so that the caliper 9 abuts against the appliance input socket 2, and the caliper 9 can limit the water extraction pipe 7 from disengaging from the side of the appliance input socket 2 towards the inner container 110.

[0047] Further, the appliance coupler water pumping device further includes: a water pump, which is arranged on the water extraction pipe 7; wherein, when the connector 1 is inserted into the appliance input socket 2, in the open state, the water pump pumps the liquid in the inner container out through the water inlet pipe 5 and the water extraction pipe 7.

[0048] The first sealing sleeve 6 and the second sealing sleeve 4 are made of rubber material. Since the rubber sealing sleeve is made of rubber material, it has the characteristics of sealing, anti-slip and elasticity.

[0049] In a specific embodiment, a clamping groove is provided in the circular hole of the connector 1, and a convex clamping buckle is provided on the outer wall of the water inlet pipe 5 corresponding to the clamping groove in the circular hole of the connector 1. The clamping connection between the water inlet pipe 5 and the connector 1 is realized through the cooperation of the clamping buckle and the clamping groove.

[0050] And a clamping groove is provided in the circular hole of the appliance input socket 2, and a convex clamping buckle is provided on the outer wall of the water extraction pipe 7 corresponding to the clamping groove in the circular hole of the appliance input socket 2. The clamping connection between the appliance input socket 2 and the water extraction pipe 7 is realized through the cooperation of the clamping buckle and the clamping groove.

[0051] The beneficial effects of the present invention are as follows: The appliance coupler water pumping device for a liquid heater with a separable inner liner provided by the present invention includes a water inlet pipe and a water extraction pipe correspondingly arranged on the connector. During operation, the water inlet pipe is inserted into the inner liner, and an elastic white environmental protection first sealing sleeve is provided at the socket. The outer wall of the first sealing sleeve is closely fitted with the housing, and at the same time, the outer wall of the first sealing sleeve is closely fitted with the inner wall of the water inlet pipe of the connector. A hard plastic water sealing slider is used to seal the backflow. The upper end of the first sealing sleeve is fitted with the bottom of the inner liner and is pressed by the housing to prevent water leakage at the bottom position of the inner liner. The other end is fitted with the water inlet pipe to prevent water leakage around the water inlet pipe. A water sealing slider is provided in the water inlet pipe and abuts against the lower socket part of the first sealing sleeve to achieve the water sealing effect. When the liquid flows through the water inlet pipe and the water extraction pipe, the water sealing slider opens the water inlet pipe under the action of water pressure, and the water flows through the water inlet pipe into the water inlet assembly and flows out of the kettle body through the water extraction pipe. When the water volume in the kettle is lower than the minimum water volume, at this time, the sealing slider covers the sealing port through the compression spring, thus achieving an excellent sealing effect.
