Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly to an electric kettle with a filtering component. Background Art

[0002] Electric kettles use electricity to quickly heat water, are easy to operate, can boil water in a very short time, and greatly facilitate people's lives.

[0003] With the progress of technology, an electric kettle with a filtering component is disclosed in the prior art (a Chinese utility model patent with the publication number CN220800762U). By providing a filtering structure inside the kettle, it can adsorb various impurities and microorganisms in tap water, thereby realizing the filtration of tap water and improving the drinking water quality. However, since tap water contains calcium and magnesium ions, these ions will decompose into insoluble carbonates when the water is heated, and then deposit on the inner wall of the kettle, which is difficult to clean. Moreover, the heat conductivity of water scale is poor. When a large amount of water scale adheres to the inner wall of the kettle, it will affect the heating efficiency of the kettle. Utility Model Content

[0004] The purpose of the present application is to provide an electric kettle with a filtering component to solve the technical problems raised in the above background art.

[0005] To achieve the above purpose, the present application provides the following technical solution: An electric kettle with a filtering component includes a kettle body, a base connected to the lower end of the kettle body, a handle fixed on the outer surface of the kettle body, a spout opened on the outer surface of the kettle body, and a kettle lid assembly rotatably connected to the upper end of the kettle body. The kettle lid assembly includes a lid body rotatably connected to the upper end of the kettle body and a filtering component provided inside the lid body. The filtering component includes a hollow sleeve provided inside the lid body, a filter rack clamped inside the hollow sleeve, an ion resin filter layer placed inside the filter rack, a screw groove opened inside the hollow sleeve, and a cover plate screwed in the screw groove.

[0006] In one embodiment, an activity groove is opened inside the lid body, and a rotating shaft is fixed on the outer surface of the hollow sleeve. The other end of the rotating shaft is rotatably connected to the inner wall of the activity groove. A slot is opened on the outer wall of the hollow sleeve, and a bolt is inserted inside the lid body. One end of the bolt penetrates through the lid body and is inserted into the slot.

[0007] In one embodiment, a clamping groove is opened inside the hollow sleeve, and an extension end integrally formed on the outer surface of the filter rack has a shape matching that of the clamping groove. The extension end is inserted into the clamping groove, and a non-woven fabric filter layer is provided at the bottom of the filter rack.

[0008] In one embodiment, a first magnetic block is fixed on the inner wall of the clamping groove, and a second magnetic block that attracts the first magnetic block is fixed inside the extension end.

[0009] In one embodiment, a sealing strip is fixedly connected to the inner wall of the movable groove, and the inner wall of the sealing strip fits against the outer surface of the hollow sleeve.

[0010] In one embodiment, a drain hole communicating with the movable groove is formed inside the cover body, and a water absorption layer is fixedly connected to the outer surface of the cover body.

[0011] In one embodiment, a screwing end is fixedly connected to the lower end of the cover plate, and the screwing end is screwed into the screw groove.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] In the present application, an ion resin filter layer is provided inside the kettle lid. When tap water passes through the kettle lid and enters the interior of the kettle body, the tap water first passes through the ion resin filter layer. Sodium ions on the resin will exchange with calcium and magnesium ions in the water. Since sodium salts have high solubility, the tap water entering the kettle body can be softened, effectively preventing the formation of water scale, avoiding the generation of a large amount of water scale on the inner wall of the kettle body, and also avoiding the influence of water scale on the heating efficiency of the kettle.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0024] Embodiment:

[0025] Please refer to Figures 1-7 , the present application provides a technical solution: an electric kettle with a filter assembly, including a kettle body 1, a base 2 connected to the lower end of the kettle body 1, a handle 11 fixed on the outer surface of the kettle body 1, a kettle spout 12 opened on the outer surface of the kettle body 1, and a kettle lid assembly 3 rotatably connected to the upper end of the kettle body 1. The kettle lid assembly 3 includes a lid body 31 rotatably connected to the upper end of the kettle body 1 and a filter assembly 33 provided inside the lid body 31. The filter assembly 33 includes a hollow sleeve 331 provided inside the lid body 31, a filter rack 335 clamped inside the hollow sleeve 331, an ion resin filter layer 338 placed inside the filter rack 335, a threaded groove 333 opened inside the hollow sleeve 331, and a cover plate 339 screwed into the threaded groove 333. The lower end of the cover plate 339 is fixedly connected with a threaded connection end 340, and the threaded connection end 340 is screwed into the threaded groove 333.

[0026] By setting the above solution, when it is necessary to fill the inside of the kettle body 1 with water for boiling, the cover plate 339 is screwed out counterclockwise from the hollow sleeve body 331, so that the ion resin filter layer 338 in the hollow sleeve body 331 (the ion resin filter layer 338 is a cation exchange resin, and in this application, the cation exchange resin can be wrapped with a mesh bag and then placed in the filter rack 335) is exposed. Then, tap water is directly allowed to fall on the ion resin filter layer 338, and the water flow passes through the ion resin filter layer 338 and flows out from the bottom of the filter rack 335 and enters the kettle body 1. The sodium ions of the ion resin filter layer 338 will exchange with the calcium and magnesium ions in the water. Since the solubility of sodium salts is high, it can soften the tap water entering the kettle body 1, effectively prevent the formation of water scale, avoid a large amount of water scale from being generated on the inner wall of the kettle body 1, and also avoid the influence of water scale on the heating efficiency of the kettle.

[0027] Please refer to Figure 4 and Figure 7 In this embodiment, an activity groove 32 is formed inside the cover body 31, and a rotating shaft 332 is fixedly connected to the outer surface of the hollow sleeve body 331. The other end of the rotating shaft 332 is rotatably connected to the inner wall of the activity groove 32, and a slot 334 is formed on the outer wall of the hollow sleeve body 331. A bolt 34 is inserted into the cover body 31, and one end of the bolt 34 penetrates through the cover body 31 and is inserted into the slot 334. Since the water in the kettle body 1 generates hot steam during heating, the hot steam may affect the exchange capacity and structural stability of the resin. If the hot steam directly rises and passes through the filter rack 335 and the ion resin filter layer 338 and then discharges, it may cause the degradation of its active groups, thereby reducing the softening effect and affecting the service life of the ion resin filter layer 338. Therefore, in this application, the hollow sleeve body 331 is rotatably arranged in the cover body 31. After the tap water enters the kettle body 1 through the ion resin filter layer 338 during water filling, the cover body 31 is rotated to turn the cover body 31 by a certain angle (less than 90 degrees), and then the cover plate 339 is screwed into the screw groove 333 in the hollow sleeve body 331. Then, the bolt 34 is pulled out from the slot 334, and the hollow sleeve body 331 is rotated (180 degrees) so that the cover plate 339 faces the kettle body 1. Then, the bolt 34 is inserted into the slot 334 again to position the hollow sleeve body 331. By blocking with the cover plate 339, the hot steam can be prevented from entering the filter rack 335 and the ion resin filter layer 338, and the service life of the ion resin filter layer 338 can be extended.

[0028] Please refer to Figure 4, in this embodiment, a clamping groove 36 is formed inside the hollow sleeve 331, and an extension end 337 matching the shape of the clamping groove 36 is integrally formed on the outer surface of the filter rack 335. The extension end 337 is inserted into the clamping groove 36. A first magnetic block 37 is fixedly connected to the inner wall of the clamping groove 36, and a second magnetic block attracting the first magnetic block 37 is fixedly connected inside the extension end 337. Through the mutual attraction of the two magnetic blocks, the extension end 337 can be prevented from moving in the clamping groove 36. At the same time, such a design also facilitates the direct removal of the filter rack 335 from the hollow sleeve 331. A non-woven fabric filter layer 336 is provided at the bottom of the filter rack 335, and the non-woven fabric filter layer 336 can filter relatively turbid tap water (if the pipeline is aged, corroded or damaged during the transportation of tap water, rust, sediment and other impurities will be mixed into the tap water).

[0029] Please refer to Figure 3 and Figure 7 , in this embodiment, a sealing strip 35 is fixedly connected to the inner wall of the movable groove 32, and the inner wall of the sealing strip 35 is attached to the outer surface of the hollow sleeve 331. The sealing strip 35 can seal the gap between the hollow sleeve 331 and the cover body 31. When the hollow sleeve 331 rotates 180 degrees, the sealing strip 35 will contact the outer surface of the cover plate 339, preventing the hot steam from discharging from the gap between the cover plate 339 and the cover body 31, thus ensuring the temperature inside the kettle body 1. The sealing strip 35 is made of rubber material and is relatively soft, and will not affect the rotation of the hollow sleeve 331 inside the cover body 31.

[0030] Please refer to Figure 2 , in this embodiment, a drain hole 39 communicating with the movable groove 32 is formed inside the cover body 31, and a water absorption layer 38 is fixedly connected to the outer surface of the cover body 31. When the hollow sleeve 331 is turned over 180 degrees inside the cover body 31, the cover plate 339 faces the kettle body 1. At this time, the filter rack 335 and the ion resin filter layer 338 will also be turned over 180 degrees. The water remaining inside the filter rack 335 and the ion resin filter layer 338 may flow out from between the hollow sleeve 331 and the cover plate 339, and the sealing strip 35 contacts the outer surface of the cover plate 339. Therefore, the flowing water will be discharged through the drain hole 39 above the sealing strip 35. The water absorption layer 38 is a sponge and can absorb the water discharged from the drain hole 39.
