Background

Silver is a precious metal, is well known to be very stable in property, is safe and non-toxic to human bodies, and has been widely used in the aspect of medicine and health for a long time due to the unique biological action of silver. The application of ancient people to silver dates back to 5000 years, and people begin to use silver to make various vessels as early as the spring, autumn and warring countries. The most common silver pot is that during the process of boiling water and containing drinking water, the silver pot can continuously release free silver ions which can soften the water quality, so that the water quality is obviously sweet when drinking. Meanwhile, the ions also have the sterilization effect on water, and can adsorb bacteria and close an enzyme system on which the bacteria live to inactivate the bacteria, so that the sterilization effect is achieved.

In the beauty, pure silver is soft, so that the ware made of the pure silver is expensive in appearance, but is easy to deform, must be maintained, is easy to lose luster and blacken and oxidize on the surface after long-term use, and is easy to leave marks particularly after being collided with hard objects. Therefore, the pure silver kettle is not popularized and popularized, and the reason is also in this respect. Based on the above, a lot of merchants on the market adopt stainless steel materials which are impact-resistant and can keep luster to manufacture kettle bodies, and the inner surfaces of the stainless steel kettle bodies, which are contacted with water, adopt a silver plating process, so that the stainless steel kettle can release free silver ions in the process of water boiling and water containing, and the stainless steel kettle achieves the effect of being beneficial to health and has a firm and durable appearance. But the same drawback is also evident, the quality of the pot is determined by the level of the silver plating process, and the plating layer thickness is generally thinner, which can cause the internal plating layer to fall off after long-term use, thereby affecting the use effect of the pot and reducing the experience of consumers.

A kettle liner structure is shown in figure 1 and comprises an outer shell and a liner 100, wherein the outer shell comprises a lower shell 200, and the liner 100 is in threaded connection with the lower shell 200.

In this embodiment, the material of the outer casing is preferably stainless steel or other metal materials such as copper, iron or plastic materials, and the material of the inner container 100 is preferably metallic silver or a metallic compound of silver, but the material of the inner container is not limited to the above materials, and may also be metallic materials such as gold and copper.

In one embodiment, as shown in fig. 2 and 3, the outer wall surface of the inner container 100 is provided with an external thread 101, as shown in fig. 4 and 5, the inner wall surface of the lower casing 200 is provided with an internal thread 201 matching with the external thread 101, and the inner container 100 is screwed with the casing 200 through the external thread 101 and the internal thread 201. Fig. 1 shows an overall state of the inner container 100 and the lower case 200 after they are connected.

As shown in fig. 2, the external thread 101 is spirally wound from the bottom surface of the inner container 100 to the top surface of the inner container 100.

As shown in fig. 5, the internal thread 201 is spirally wound from the bottom surface of the lower case 200 to the top surface of the lower case 200.

The inner container 100 and the lower shell 200 adopt the full-spiral connection mode as above, compare the mode that only the top part of the inner container 100 is connected spirally or the bottom part of the inner container 100 is connected spirally, the mode of full-spiral connection has reduced the gap between the inner container 100 and the lower shell 200 well, can even make complete vacuum between the inner container 100 and the lower shell 200, make the inner container 100 and the lower shell 200 laminate better, reduce the influence of the phenomenon of thermal expansion and cold contraction on the inner container 100 from this, make the inner container 100 basically not produce the deformation after long-time use, thereby promote the life of the inner container 100.

In one embodiment, the spiral angle of the external thread 101 and the internal thread 201 is 5-15 °, so that a slow spiral speed can be ensured when the liner 100 is screwed into the lower casing 200, damage to the liner 100 due to too fast screwing can be prevented, and the liner 100 and the lower casing 200 can be more tightly combined after being screwed into the casing.

As shown in fig. 6, the outer case further includes an upper case 300, and the upper case 300 is fixedly connected to the lower case 200.

Specifically, the upper case 300 and the lower case 200 may be welded at the welding position 400 by flame welding, induction welding, furnace welding, laser welding, or the like.

The upper case 300 is made of stainless steel of the same type as the lower case 200.

In this embodiment, the manufacturing method of the inner container structure of the kettle comprises the following steps:

(1) making inner container and lower shell

Manufacturing a silver liner with external threads and a stainless steel lower shell with internal threads in a die opening mode;

(2) the inner container and the lower shell are connected

Fixing the inner container on a rotary jig, and slowly screwing the inner container into the lower shell along the rotating track of the internal thread and the external thread until the inner container rotates to the bottom of the internal thread;

(3) the upper shell and the lower shell are connected

And welding the bottom of the upper shell with the top of the lower shell provided with the inner container.

In the manufacturing method according to this embodiment, in order to reduce the gap between the inner container 100 and the lower case 200 and prevent water from entering the gap between the inner container 100 and the lower case 200, the gap between the inner container 100 and the lower case 200 may be completely attached to each other in a vacuum state.

Specifically, in step (2), after the inner container 100 is connected to the lower casing 200, a water swelling process is first used to make the surfaces of the inner container 100 and the lower casing 200 closely contact with each other, so as to further reduce the space (the gap) between the inner container 100 and the lower casing 200 or make the inner container 100 and the lower casing 200 completely vacuum (tight bonding, no gap exists). In order to further ensure that water does not leak out from the space between the inner container 100 and the lower shell 200, before the inner container 100 is connected with the lower shell 200, a layer of heat-conducting silicone grease with the thickness of 0.5-2mm is coated at the bottom of the inner container 100, on one hand, the heat-conducting silicone grease can fill the gap, and further ensure that water does not enter the space between the inner container 100 and the lower shell 200, on the other hand, the inner container structure of the kettle in the embodiment is in a bottom heating mode, namely, the heating part is arranged at the bottom of a product, and by adding the heat-conducting silicone grease, the heat conductivity coefficient during heating can be improved, and the water boiling speed is improved.

This embodiment still provides a kettle, the kettle has included the kettle inner bag structure that this embodiment provided.

The inner container structure of the kettle provided by the invention connects the silver inner container and the stainless steel lower shell through threads in a physical mechanical processing mode, thus solving the bonding obstacle between different materials, and particularly solving the problem that the two bonding materials are displaced mutually due to different expansion rates of different materials during heating; meanwhile, the mode of threaded connection has better fixing effect, so that the inner container is tightly combined with the lower shell, and the heat conduction effect of the inner container cannot be influenced.

The traditional metal materials or the combination of different materials generally adopt welding or electroplating process, so that the production cost is higher, the durability is poor, and the environment is not protected. The manufacturing method provided by the invention adopts a physical machining mode, has a simple production mode, is environment-friendly, has a good effect, and can better keep various excellent performances of raw materials.
