Description
Technical Field
[0001] The utility model belongs to the field of kettle body heat preservation and insulation structure, specifically a split-type integrally formed vacuum kettle. Background Art
[0002] In order to avoid scalding, kettles also need to slow down the rate at which water temperature drops so that the substances in the tea leaves can be released as much as possible when brewing tea. Therefore, kettles are usually made into structures with vacuum insulation. Although this can keep the water warm, the spout is relatively long. For example, in the public technical document "CN214631651U, a vacuum insulation electric kettle", when the water in the kettle exceeds the connection between the inner tank and the spout, the water will flow into the long spout, and the spout is directly exposed to the outside space. Therefore, the temperature of the water will be directly dissipated to the outside space through the spout, and this speed is very fast, causing the water temperature to drop rapidly. Therefore, making a vacuum insulation layer on the kettle body alone for insulation is not comprehensive. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0024] Please refer to Figure 1-3 ;
[0025] The vacuum kettle of the present invention adopts a more comprehensive heat preservation method, which further improves the heat preservation effect. It specifically comprises an inner liner 1, an outer liner 2, an inner spout 5 and an outer spout 6. These four parts are separately made and formed before assembly; the inner liner 1 is placed in the outer liner 2, and the inner liner 1 and the outer liner 2 are connected by laser welding to form a partition 3 between the two. In one embodiment, the upper and lower edges of the inner liner 1 and the outer liner 2 are respectively connected and fixed. However, since the present invention is positioned as a kettle, electronic components need to be installed, so an external base is used to be installed at the bottom of the inner liner 1; another way is that the base 4 is welded The bottom of the inner liner 1 is pre-fixed in the form of a base 4, and a hollow is formed in the middle of the base 4 for installing electronic components; the inner liner 1 is then placed in the outer liner 2 together with the base 4, and the upper edge of the inner liner 1 is connected to the upper edge of the outer liner 2 by laser welding, and the outer periphery of the base 4 is connected to the bottom edge of the outer liner 2. After the connection is completed, a partition 3 is formed between the three. It should be noted that the inner liner 1 is the main container component for holding liquids. It is not enough to rely solely on the upper edge of the inner liner 1 and the upper side of the outer liner 2 as a fixed point. In this embodiment, the base 4 can not only prevent the inner liner 1 from shifting and keeping it centered, but also serve as a support for the inner liner 1, thereby reducing the pressure on the inner liner 1;
[0026] When making the inner liner 1 and the outer liner 2, a water outlet will be reserved on the side wall of the inner liner 1, and a through hole 21 will be reserved on the outer liner 2 for the inner spout 5 to pass through. The aperture of the through hole 21 is larger than the maximum size of the inner spout 5. Then the inner spout 5 is inserted into the through hole 21 so that its end corresponds to the position of the water outlet and is close to the side wall of the inner liner 1. It is then fixed by laser welding, and the outer spout 6 is sleeved on the outer periphery of the inner spout 5. Laser welding is also used to connect one end of the outer spout 6 to the outer periphery of the outer liner 2, and the other end is connected to the water outlet end 51 of the inner spout 5. At this time, a partition 2 7 is formed between the inner spout 5 and the outer spout 6, and the partition 1 3 and the partition 2 7 are connected to each other. Under normal circumstances, the upper and lower edges of the outer liner 2 will extend toward the middle by folding, and be connected to the inner liner 1 and the base 4 respectively. An exhaust hole will also be reserved at the folding position for vacuum extraction;
[0027] After completing the above connection process, the whole is placed in an oven. The principle of thermal expansion and contraction is used to expand the air in the interlayer 1 3 and the interlayer 2 7 and discharge it from the exhaust hole. Finally, the exhaust hole is sealed by dotting glass beads. After cooling, the interlayer 1 3 and the interlayer 2 7 form a vacuum state. Of course, this is only one of the production methods. There should be production methods with different orders or other steps, which will not be described one by one here.
[0028] The present invention forms a vacuum interlayer 1 3 and a vacuum interlayer 2 7 through the above-mentioned manufacturing process to insulate the kettle body and the spout respectively. When the water in the kettle body is at a higher water level and flows into the spout, this part of the water is still in the insulation layer. Although the water outlet of the spout is connected to the outside world, so that part of the water surface is in contact with the outside world and causes temperature loss, the heat loss of this part is much less than that of dissipating heat outward through the entire spout, which can effectively slow down the heat dissipation and extend the insulation time. In addition, the spout will not be hot, especially when the water is boiling, to avoid scalding the user.
[0029] Under normal circumstances, the closer the space of the second partition 7 is to the connection between the inner spout 5 and the outer spout 6, the smaller the space it occupies, that is, the smaller the distance between the inner spout 5 and the outer spout 6 will be, so that the use of a vacuum method does not form a real vacuum environment, and more or less gas will be produced. When the distance is less than 2 cm, heat radiation will be generated from the inner spout 5 to the outer spout 6, that is, the heat will be transferred to the outer spout 6 before reaching the connection end, which in disguise increases the area of heat transfer; in the embodiment of the present invention, the water outlet end 51 of the inner spout 5 is in the shape of an arc-shaped trumpet extending outward, and the end of the outer spout 6 is a straight cylinder, and the end edge of the outer spout 6 is connected to the end edge of the inner spout 5. Such a structure can ensure that the distance between the outer spout 6 and the inner spout 5 is greater than the distance for generating heat radiation. In addition, the water outlet end 51 is an arc-shaped design, which can make the water outlet smoother.
[0030] In the embodiment of the present invention, the water outlet of the inner tank 1 can be formed by laser cutting to cut a plurality of small holes 111 on its side wall. Figure 2 Then use a clamp to fix the pot body and the inner spout 5 respectively, and then use a laser to fix the two. Another way to fix the water outlet is to form a large water outlet hole 112 by expansion. Figure 3 Based on the case of a large water outlet, the edge around the water outlet is turned outward to form a flange 12. During assembly, the flange 12 extends into the inner spout 5 and conflicts with the inner wall of the inner spout 5, which can pre-fix the spout and facilitate subsequent welding; similarly, the through hole 21 located in the outer liner 2 is bent outward to form a flange 22, which extends into the outer spout 6 and conflicts with the inner wall of the outer spout 6, thereby playing a pre-fixing effect.
[0031] Preferably, the flange 1 (12) is in the shape of a curved trumpet, and the end of the inner spout 5 connected to the inner pot 1 is formed in the shape of a curved trumpet, which is adapted to the end of the inner spout 5, so that the connection end of the inner spout 5 can be better fitted with the flange 12. In addition, the end of the outer spout 6 connected to the outer pot 2 is turned outward to form a flange 22. Preferably, the flange 22 is in the shape of a curved trumpet, which is adapted to the end of the outer spout 6, so that the connection end of the outer spout 6 can be better fitted with the flange 22.
[0032] Preferably, the water outlet 112 and the through hole 21 are non-circular in shape, so as to play a positioning role during assembly production, avoid rotational deviation, and better align the various components.
[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
