Description

Technical Field

[0001] This utility model relates to the field of electric water bottles, specifically to a detachable electric water bottle. Background Technology

[0002] Currently, electric kettles are equipped with an electric heater to heat the water inside. Commercially available electric kettles also have a water pump that pumps water to the spout. To accommodate cups or kettles placed below the spout, the spout needs to be positioned relatively high. When adding water, opening the cap and pouring it into the kettle can cause water to splash onto the electrical components, posing a safety hazard. Without a ladle, the entire kettle must be carried to the tap, further increasing the risk of wetting the electrical components. Therefore, detachable electric kettles have emerged; for example, Chinese Utility Model Patent Publication No. CN219479805U, "An Electric Kettle," includes a water tank and a base. The water tank has an upper coupler, and the base has a lower coupler. The upper coupler has an upper connecting device. The upper water core and lower coupler are equipped with a lower water core with a lower channel. When the water tank is placed on the base, the upper coupler and lower coupler are coupled, the upper water core and lower water core are connected, and the upper channel and lower channel form a water passage that can be opened and closed. The outer side wall of the upper part of the lower water core is equipped with a lower sealing ring. The lower water core is inserted into the upper water core, and the outer side wall of the lower water core forms a side seal with the inner side wall of the upper water core through the lower sealing ring. Because the water outlet is located high, the base is set high, and the height difference between the front and rear parts of the base is large (the water outlet is located in the upper front part of the base). After the water tank is separated from the base, the user is prone to bumping into the base, which can easily cause the base to tip over. Moreover, the base occupies a lot of space. When the user puts the water tank back on the base, they need to approach the base in a certain direction. That is, they must lift the water tank high and put it down vertically or approach the base from the back at an angle to avoid the raised front of the base. It is inconvenient to use and needs to be improved. Summary of the Invention

Detailed Implementation

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] This utility model relates to a detachable electric hot water bottle, such as... Figures 1 to 5 As shown, the device includes a water bottle body 1, a base 2, and a water-electric coupling assembly 4. The water-electric coupling assembly 4 includes a lower coupler 41 and an upper coupler 42. The lower coupler 41 is located on the base 2, and the upper coupler 42 is located at the bottom of the water bottle body 1. The water bottle body 1 has an inner liner 12, and an electric heating element is located on the lower side of the bottom of the inner liner 12. The base 2 is connected to a power cord, so the electric heating element is connected to the power source through the water-electric coupling assembly 4. The lower coupler 41 and the upper coupler 42 are existing technologies. For example, you can refer to the "An Electric Water Bottle" with Chinese Utility Model Patent Publication No. CN219479805U or the "A Device Coupler Water Pumping Device" with Chinese Utility Model Patent Publication No. CN212698540U. The water bottle body 1 is placed on the base 2, so that the lower coupler 41 and the upper coupler 42 are coupled together. When the water bottle body 1 is picked up, the upper coupler 42 moves up away from the lower coupler 41.

[0025] like Figure 5 As shown, the detachable electric kettle of this utility model also includes a water inlet connector 3 and a water pump 5, with the water pump 5 located inside the base 2. Figures 6 to 8 As shown, the water inlet connector 3 includes a valve housing 32, within which a valve cavity 3201 is formed. A valve port 34 is formed at the lower end of the valve cavity 3201. The water inlet connector 3 includes a valve core 31 for closing or opening the valve port 34 and a water-passing push rod 33 for lifting the valve core 31 to open the valve port 34. When the valve core 31 opens the valve port 34, the water-passing push rod 33 can communicate with the valve cavity 3201 through the valve port 34. The valve core 31 slides vertically within the valve housing 32. Specifically, the valve core 31 has an outer cylindrical surface, and the lower end of the valve port 34 has a cylindrical hole. The outer cylindrical surface and the cylindrical hole are adapted to each other for connection. Figure 2 and Figure 6As shown, the water-passing push rod 33 is located on the base 2, and the valve housing 32 is located inside the lower end of the water bottle body 1. Therefore, the valve core 31 is also located inside the lower end of the water bottle body 1. Figure 3 and Figure 5 As shown, the upper part of the water bottle body 1 is provided with a water outlet 112. The water outlet 112 is connected to the valve chamber 3201 through the water supply pipe 6. The water inlet end of the water pump 5 is connected to the lower coupler 41 through the corresponding pipe (which can be a flexible hose). The water outlet end of the water pump 5 is connected to the water inlet connector 331 at the lower end of the water push rod 33 mentioned above through the corresponding pipe.

[0026] The working principle of this utility model's detachable electric hot water bottle is briefly explained below: Figure 1 As shown, when the electric hot water bottle of this utility model is in working condition, the bottle body 1 is placed on the base 2, and the water push rod 33 pushes up the valve core 31, so that the valve port 34 is opened. That is to say, at this time, the water push rod 33 connects to the valve cavity 3201 through the valve port 34. When the water pump 5 is working, the water pump 5 draws water from the bottle body 1. Specifically, the water in the bottle body 1 flows downward through the upper coupler 42 to the lower coupler 41, and then flows through the water pump 5. The water is output from the water pump 5 to the water push rod 33, and the water flows through the valve port 34 to the valve cavity 3201. The water then enters the water supply pipe 6, and the water flows upward along the water supply pipe 6 to the outlet 112, so that the water is discharged downward from the outlet 112. A handle is hinged to the upper end of the water bottle body 1. The user lifts the water bottle body 1 by the handle, causing the upper coupler 42 to separate from the lower coupler 41. Simultaneously, the valve core 31 moves upward, separating from the water-passing push rod 33. Since the upper coupler 42 and lower coupler 41 are separated, the water bottle body 1 is not energized. When the user takes the water bottle body 1 to the tap to fill it with water, water will not splash into the base 2, and there is no need to disconnect the power cord from the wall socket. Figure 1 and Figure 2 As shown, by setting the water inlet connector 3 and the water supply pipe 6, the water outlet 112 can be arranged on the upper part of the water bottle body 1, which avoids the need to place the water outlet 112 on the base 2. This allows the height of the base 2 to be set smaller. Therefore, when the user puts the water bottle body 1 back on the base 2 to connect the upper coupler 42 to the lower coupler 41, it is not necessary to lift the water bottle body 1 high, which saves effort. Moreover, because the height of the base 2 is set smaller, even if the water bottle body 1 is lifted at a relatively low height, the water bottle body 1 can be brought close to the top of the base 2 in all directions in the horizontal plane and then put down. Therefore, the electric hot water bottle of this utility model is more convenient to use, and the user is less likely to knock over the base 2, thus avoiding safety problems caused by the base 2 tipping over.

[0027] Furthermore, such as Figure 8As shown, the water inlet connector 3 includes a return spring 36 for driving the valve core 31 to move downward to close the valve port 34. The upper end of the return spring 36 is connected to the valve housing 32, and the lower end of the return spring 36 is connected to the valve core 31. Therefore, when the water bottle body 1 is lifted off the base 2, the elastic restoring force of the return spring 36 pushes the valve core 31 downward, so that the valve core 31 quickly closes the valve port 34. This can prevent a large amount of water in the water supply pipe 6 from flowing back through the valve port 34. In other words, it speeds up the reset speed of the valve core 31 and improves the reset stability and reliability of the valve core 31. It also avoids the valve port 34 from being poorly closed because the valve core 31 moves downward to reset only by gravity (including the gravity of the valve core 31 and the gravity of the water in the water supply pipe 6). When the water bottle body 1 is placed on the base 2, the upper end of the water push rod 33 pushes the valve core 31 upward, causing the valve core 31 to open the valve port 34. At the same time, the return spring 36 is further elastically compressed and deformed. Through the elastic restoring force of the return spring 36, the water push rod 33 is also well attached to the valve core 31.

[0028] Furthermore, such as Figure 8 As shown, a water inlet chamber 310 is formed inside the valve core 31, and the water inlet chamber 310 extends through the lower end of the valve core 31. The upper end of the valve core 31 is provided with a valve port sealing ring 314 for contacting and connecting the valve port 34. Specifically, as shown... Figure 9 As shown in Figure 8, an annular groove 313 is formed at the upper end of the valve core 31. The valve port sealing ring 314 is appropriately fitted into the annular groove 313. Therefore, the valve core 31 body can be made of plastic, while the valve port sealing ring 314 can be made of silicone rubber. Figure 9 As shown, a water outlet window 311 is formed on the upper part of the valve core 31. The water outlet windows 311 are evenly distributed around the circumference and are connected to the water inlet chamber 310. Figure 8 As shown, the water outlet window 311 is located below the valve port sealing ring 314, and the upper end of the water-passing push rod 33 can connect to the lower end of the water inlet chamber 310. That is to say, when the water bottle body 1 and the base 2 are in a certain position... Figure 5 In the indicated usage state, the upper end of the water-passing push rod 33 is directly opposite the lower end of the water inlet chamber 310. When the water bottle body 1 is separated from the base 2, the water inlet chamber 310 moves away from the water-passing push rod 33. Figure 8 As shown, since the water outlet window 311 is located below the valve port sealing ring 314, the valve core 31 moves downward, and the valve port sealing ring 314 contacts the valve port 34, thus closing the valve port 34. This also separates the valve cavity 3201 from the water outlet window 311 on the upper and lower sides of the valve port sealing ring 314. The upper part of the valve port 34 can form an inverted inner conical surface, and the lower part of the valve port sealing ring 314 forms an inverted outer conical surface. When the valve port 34 is closed, the aforementioned inverted inner conical surface fits and abuts against the aforementioned inverted outer conical surface. Through the elastic restoring force of the return spring 36, the valve port sealing ring 314 presses down on the valve port 34, thereby forming a good seal.

[0029] Furthermore, such as Figure 9 As shown, a disc 312 is formed at the lower end of the valve core 31, as... Figure 8 As shown, the lower end of the return spring 36 is attached to the upper side of the disc 312, and the valve core 31 is fitted with a sealing sleeve 37. The sealing sleeve 37 is sandwiched between the upper side of the disc 312 and the lower side of the edge of the valve port 34. Therefore, when the water push rod 33 opens the valve port 34, the sealing sleeve 37 can intercept the water leaking from the gap between the lower end of the valve port 34 and the outer wall of the valve core 31.

[0030] Furthermore, such as Figure 8 As shown, the upper end of the water-passing push rod 33 is provided with a sealing ring gasket 35 for contacting the lower part of the connecting disc 312. Specifically, the upper end face of the water-passing push rod 33 forms an annular lower groove, and the sealing ring gasket 35 is disposed in the above-mentioned annular lower groove, thereby preventing the sealing ring gasket 35 from easily falling out. When the water bottle body 1 is connected to the base 2, the sealing ring gasket 35 is pressed against the lower part of the disc 312 by the elastic restoring force of the return spring 36, thereby sealing the upper end of the water-passing push rod 33 with the lower end of the valve core 31.

[0031] Furthermore, such as Figure 5 As shown, the water bottle body 1 includes an outer shell assembly 11 and an inner liner 12. The inner liner 12 is disposed inside the outer shell assembly 11, and a cavity 100 is formed between the outer wall of the inner liner 12 and the inner wall of the outer shell assembly 11. A water supply pipe 6 is disposed within the cavity 100. The water supply pipe 6 can be a silicone rubber hose. A water outlet pipe is provided at the upper part of the outer shell assembly 11, and a water outlet 112 is formed at the lower end of the water outlet pipe. One end of the water supply pipe 6 is sleeved onto the upper end of the water outlet pipe. Figure 7 and Figure 8 As shown, the valve housing 32 includes a valve body 321 and a valve cover 322. A valve port 34 is formed within the valve body 321, and a valve cavity 3201 is formed within the upper part of the valve body 321. The valve cover 322 covers the upper side of the valve body 321. A sealing element 38 is provided between the valve body 321 and the valve cover 322. A water outlet connector 3221 is formed on the top of the valve cover 322, and the corresponding other end of the water supply pipe 6 is sleeved onto the water outlet connector 3221. Specifically, the water supply pipe 6 bypasses the outer wall of the inner liner 12. By placing the water supply pipe 6 within the cavity 100, the water supply pipe 6 can be hidden, which is beneficial for protecting the water supply pipe 6 and also helps to keep the appearance of the electric kettle simple.

[0032] Furthermore, such as Figure 2 As shown, a pelvic cavity 20 is formed inside the base 2, such as Figure 3 Combination Figure 5 As shown, the lower end of the outer casing assembly 11 is fitted into the basin cavity 20, thereby coupling the lower coupler 41 with the upper coupler 42, and causing the water-passing push rod 33 to lift the valve core 31. The basin cavity 20 positions the water bottle body 1, and the water-passing push rod 33 is fixedly located at the bottom of the basin cavity 20. Specifically, as shown... Figure 6 As shown, the base 2 has an inner bottom plate 201, which serves as the bottom of the pelvic cavity 20. The water-passing push rod 33 is fixedly connected to the inner bottom plate 201 by corresponding screws. The upper end of the water-passing push rod 33 protrudes upward from the inner bottom plate 201, as shown. Figure 4 The water pump 5 shown is located on the underside of the inner base plate 201. For example... Figure 6 As shown, the valve housing 32 is located inside the lower end of the housing assembly 11, specifically, as... Figure 2 As shown, the lower end of the outer casing assembly 11 forms a bottle bottom 111, and the valve cap 322 is mounted to the bottle bottom 111 by corresponding screws. The valve body 321 is sandwiched between the valve cap 322 and the upper side of the bottle bottom 111; Figure 2 As shown, the lower coupler 41 is located in the middle of the inner bottom plate 201. Figure 2 As shown, the upper part of the electric hot water bottle of this utility model can be completely separated from the base 2, making the electric hot water bottle product more integrated.
