The liquid heating container provided by the embodiment of the present aspect has the beneficial effects of any one of the above technical solutions due to the stirring assembly of any one of the above technical solutions, which is not repeated herein.

In some embodiments, as shown in fig. 16, the container port 210 is provided at the upper end of the container body 20, and the diameter of the coverage area when the stirring blade 120 rotates is smaller than the size of the container port 210.

In these embodiments, the container mouth 210 is provided at the upper end of the container body 20, and the diameter of the coverage area when the stirring blade 120 rotates is smaller than the size of the container mouth 210. So set up, on the one hand, convenience of customers takes out and installs stirring leaf 120 via container mouth 210, is favorable to the washing of stirring leaf 120, installation, and on the other hand can prevent to collide with container body 20 when stirring leaf 120 takes, causes container body 20 to collide with the wound, especially when container body 20 is the glass material, can avoid glass container body 20 to be collided with badly.

In some embodiments, as shown in fig. 15 and 16, the container body 20 further includes a container cover 211, and the container cover 211 covers the container opening 210 and seals the container opening 210 to prevent dust.

In some embodiments, as shown in fig. 15 and 16, the container body 20 is detachably mounted on a base 220, the base 220 is used for supporting the container body 20, and a power supply member may be provided in the base 220, for example, a power line and a first coupling member may be provided on the base 220, a second coupling member electrically connected to the first coupling member may be provided on the container body 20 for supplying power to the container body 20, and the power supply member may be provided in the base to reduce the weight of the container body 20, thereby facilitating a user to take the container body 20 for water pouring or the like.

Further, the rotation speed of the stirring blades 120 is 20r/min to 30r/min, and in this range, on one hand, the stirring effect of the stirring blades 120 can be ensured, and uneven stirring caused by too low stirring speed is avoided; on the other hand, the food materials can be prevented from being damaged due to the fact that the stirring speed is too high, and the taste is not influenced.

The liquid heating container provided by the embodiment of the aspect realizes that the stirring blade 120 slightly damages the food material and does not smash the food material when stirring the food material by controlling the rotating speed of the stirring blade 120, the shape radian and the size of the stirring blade 120 and the weight of the stirring blade 120, so that the best taste is realized, and the use experience of a user on stirring products is improved.

Further, the liquid heating container is a health preserving pot, a health preserving cup, a teapot, a coffee pot, or the like.

In some embodiments, as shown in fig. 2, 10 and 11, the liquid heating vessel comprises a floor assembly comprising: a disc body 110; stirring subassembly, the setting is in the top of set body 110, and stirring subassembly rotationally is connected with set body 110, and stirring subassembly is including the stirring leaf 120 that has blade 121, and the lower surface of blade 121 is the plane, and the value range of the ratio of the diameter A of coverage satisfies when distance H between the lower surface of blade 121 and the set body 110 rotates with stirring leaf 120: H/A is more than or equal to 0.0025 and less than or equal to 0.06.

In these embodiments, the base plate assembly includes a plate body 110 and a stirring assembly, the stirring assembly includes a stirring blade 120, the stirring blade 120 can rotate above the plate body 110 to stir the food material, so as to prevent the food material from being pasted on the plate body 110, the lower surface of the blade 121 of the stirring blade 120 is a plane, so that the distance between the blade 121 and the plate body 110 is equal everywhere, the distance between the blade 121 and the plate body 110 can be reduced as much as possible, and thus the food material near the plate body 110 can be stirred better; further, the ratio of the distance H between the lower surface of the blade 121 and the disk body 110 to the diameter a of the coverage area when the stirring vanes 120 rotate ranges from 0.0025 to 0.06, and thus, the inevitable shaking and tilting of the stirring vanes 120 during the rotation process are taken into consideration comprehensively, because the stirring vanes 120 have weight, the larger the coverage area of the stirring vanes 120 is, the more the center of gravity shifts toward the end of the stirring vanes 120; when encountering an obstacle, the larger the generated moment is, the easier the moment is to shake and scrape the disc body 110, so the stirring blades 120 need a higher distance; the smaller the coverage area of the stirring blade 120 is, the smaller the moment generated when the stirring blade meets an obstacle is, and the less the stirring blade is easy to shake. Therefore, the larger the diameter of the coverage area of the stirring blade 120 is, the larger the amplitude of shaking and tilting is, the easier it is to scrape the disc body 110, and on the premise of not scraping the disc body 110, the closer the distance between the lower surface of the blade 121 and the disc body 110 is, the better the effect of stirring the food material can be achieved, therefore, the value range of the ratio of the distance H between the lower surface of the blade 121 and the disc body 110 to the diameter a of the coverage area when the stirring blade 120 rotates is defined to be 0.0025 to 0.06, so that the distance between the lower surface of the blade 121 and the disc body 110 is reasonable, the food material close to the disc body 110 cannot be stirred too much, the food material bottom-sticking phenomenon cannot be caused, the problem that the stirring component shakes and tilts, the disc body 110 cannot be scraped due to too small size, the scratching of the disc body 110 can be caused, and the problem that sharp and harsh scraping sound is generated can be caused.

Further, in some embodiments, as shown in fig. 10, the distance H between the lower surface of the blade 121 and the disk body 110 is 0.5mm or more and 3mm or less. So set up, avoided the distance too big and lead to being close to the edible material of dish body 110 and can not play the stirring effect, can give edible material one to the extrusion force of dish body 110 direction on the contrary, the phenomenon that the end is stuck with paste with higher speed of dish body 110 has also avoided the distance very little easy scraping dish body 110, produces sharp-pointed harsh scraping sound, experiences and feels poor. Because the volume of beans such as red bean, mung bean commonly used is less, according to experimental verification, the problem that beans are clamped between the blades 121 and the plate body 110 easily appears for 3mm in distance H between the lower surface of the blades 121 and the plate body 110, not only can the stirring blades shake, but also the beans are crushed greatly, even the taste is influenced because the heating paste is on the plate body 110, therefore, the distance H between the lower surface of the blades 121 and the plate body 110 is preferably selected to be about 2 mm. It should be noted that, in practical applications, the diameter a of the coverage area when the stirring blade 120 rotates is generally between 50mm and 200mm, preferably 116mm, considering the size of the container mouth 210 and the size of the disc body 110.

In some embodiments, as shown in fig. 11 to 14, the stirring vane 120 includes a blade 121 and a central portion 122, and as shown in fig. 12, a ratio of a distance E between a lower surface of the central portion 122 and a lower surface of the blade 121 to a distance H between the lower surface of the blade 121 and the disc body 110 satisfies: E/H is more than or equal to 0 and less than or equal to 0.5; and the lower surface of the central portion 122 is lower than or flush with the lower surface of the blade 121.

In these embodiments, the vanes 121 are disposed around a central portion 122, the central portion 122 serving to support the vanes 121; the lower surface of the central portion 122 is lower than or flush with the lower surface of the blade 121, and the central portion 122 is located at the center of the stirring blade 120, and the blade 121 is distributed around the central portion 122, so that the position of the central portion 122 is shaken and the inclination amplitude of the central portion 122 is smaller than that of the blade 121 in the rotating process of the stirring blade 120, therefore, the lower surface of the central portion 122 is slightly lower than the lower surface of the blade 121, and the lower surface of the central portion 122 is not scratched by the disk body 110, and the connection between the central portion 122 and the blade 121 is facilitated, so that the connection between the central portion 122 and the blade 121 is stable. Further, the ratio of the distance E between the lower surface of the central portion 122 and the lower surface of the blade 121 to the distance H between the lower surface of the blade 121 and the disk body 110 satisfies: E/H is 0 or more and 0.5 or less, which neither makes the central portion 122 too close to the disk body 110 to have a risk of scratching the disk body 110, nor makes the central portion 122 higher than the blades 121 to cause an edge of the blades 121 not to be completely fixed on the central portion 122, which causes a risk of easily breaking the connection between the blades 121 and the central portion 122.

Preferably, the distance E between the lower surface of the central portion 122 and the lower surface of the blade 121 is 0mm or more and 1mm or less. The lower surface of the central portion 122 is slightly lower than the lower surface of the blades 121, which is beneficial to the connection between the central portion 122 and the blades 121, so that the connection between the central portion 122 and the blades 121 is stable, and the blades are not scratched on the disk body 110.

In these embodiments, the end close to the central portion 122 is the first end of the blade 121, the end far from the central portion 122 is the second end of the blade 121, and the upper surface of the blade 121 is defined as an arc surface gradually rising from the first end of the blade 121 to the second end of the blade 121, and at the same time, the height F of the first end of the blade 121 is defined to be smaller than the height G of the second end of the blade 121, because the food material will move centrifugally during the stirring process, and the food material will move outwards away from the center of the stirring blade 120, that is, the food material will move towards the second end of the blade 121 away from the first end of the blade 121, so that the food material at the first end of the blade 121 is less, and the food material at the second end of the blade 121 is more, and therefore, the size G is set to be larger than the size F, so as to realize that the stirring blade 120 near the rotation center is less short and the outer ring of the stirring blade 120 far from the rotation center is higher, the food materials are stirred more, the motion rule of the food materials is met, and the food materials are stirred more uniformly. Further, the arc radius R1 of the upper surface of the blade 121 is related to the diameter of the stirring blade 120, the radian of the upper surface of the stirring blade 121 can be adjusted according to the diameter of the stirring blade 120, and the upper surface of the blade 121 is smoothly transited from the first end to the second end, and the height of the blade 121 is gradually increased, so that the structure of the blade 121 is more reasonable.

In some embodiments, as shown in fig. 12, the first end height F of the blade 121 is greater than or equal to 10mm and less than or equal to 12 mm; the second end height G of the blade 121 is equal to or greater than 14mm and equal to or less than 18 mm; the outer edge of the second end of the blade 121 has a circular arc shape, and the radius R2 of the circular arc size of the outer edge of the second end of the blade 121 is not less than 5mm and not more than half the height of the second end of the blade 121.

In these embodiments, the first end height F of the blade 121 and the second end height G of the blade 121 are further defined, so that the problems that the force applied to the stirring blade 120 is too large when the stirring blade 120 rotates due to too large height of the blade 121, the driving force required by the stirring blade 120 is too large, and the rotation of the stirring blade 120 is difficult are avoided, and the problems that the food material stirring effect is influenced due to too small height of the blade 121, and the food material stirring is not uniform are also avoided. Further, the outer edge of the second end is arc-shaped, so that the edge of the stirring blade 120 is smooth, hands are prevented from being scratched during cleaning, and the edge of the blade 121 is prevented from being deformed to scratch the disc body 110; the radius R2 of the arc size of the outer edge of the second end is greater than or equal to 5mm and less than or equal to half of the height of the second end of the blade 121, so that the transition of the joint of the arc and the blade 121 is smooth, a sharp angle is not formed, and the processing of the blade 121 is facilitated.

Due to the arrangement, the radian of the stirring blade 120 is related to the diameter size, the radian of the stirring blade 120 can be adjusted according to the diameter size of the stirring blade 120, and then the stirring state of the stirring blade 120 can be controlled through the radian of the blade 121, if the radian of the blade 121 is too large, the food materials can be gathered at the center of the radian to roll when being stirred, and the effect of uniform stirring cannot be achieved; and if the radian of the blade 121 is too small, the blade 121 cannot play a good buffering role in the rotating process of the blade 121, the food material is easily clamped below the stirring blade 120 to cause bottom pasting, and the food material can move centrifugally in the stirring process and move outwards away from the center of the stirring blade 120, the arc-shaped blade 121 can gather the food material around the blade 121 as far as possible, so that the stirring effect is realized, and the blade 121 is too straight, so that most of the food material is thrown to a range outside the blade 121, and the food material cannot be uniformly stirred, and the food material is easily accumulated between the blade 121 and the side wall of the container body 20, so that the container body 20 is difficult to clean.

Optionally, the arc radius R3 of the blade 121 is equal to or greater than 50mm and equal to or less than 55 mm.

In some embodiments, as shown in FIG. 11, the thickness B of the blade 121 is 2mm or greater and 2.5mm or less. In this range, on one hand, the influence of the hand scraping when the stirring blade 120 is cleaned due to the fact that the thickness of the blade 121 is too small and the blade 121 is too thin is avoided, and the use experience is influenced; on the other hand, the risk that the stirring blade 120 is too heavy due to the excessive thickness of the blade 121 and the container main body 20 is broken or damaged when the stirring blade 120 is taken is also avoided.

In these embodiments, the stirring assembly includes a stirring blade 120, a stirring shaft 130, a sealing ring 140 and a stopper 1223, wherein the bottom of the center of the stirring blade 120 is provided with a shaft hole 1222 with a downward opening, and a mounting groove 1221 located below the shaft hole 1222 and communicated with the shaft hole 1222, so that the stirring shaft 130 can be conveniently inserted into the shaft hole 1222, the sealing ring 140 sleeved on the stirring shaft 130 can be just located in the mounting groove 1221, the stopper 1223 capable of blocking part of the opening of the mounting groove 1221 is further located below the mounting groove 1221, so that the stopper 1223 can block the sealing ring 140 in the mounting groove 1221, thereby effectively preventing the stirring blade 120 from being separated from the stirring shaft 130 when the food material is poured out through the cooperation of the sealing ring 140 and the stopper 1223, and when the stirring blade 120 needs to be cleaned, the sealing ring 140 can be separated from the stopper 1223 with a slight force, thereby removing the stirring blade 120 for cleaning, not only can the anti-dropping effect of the stirring blade 120 be realized, but also the stirring blade 120 is convenient to detach and clean. Compared with the structure that the sealing ring 140 and the stirring blade 120 are assembled into a whole, the scheme that the stirring blade 120 can be taken out along with the sealing ring 140 is adopted, the sealing ring 140 is sleeved on the stirring shaft 130 and cannot be taken out along with the stirring blade 120, only the single structure of the stirring blade 120 is taken out, and the cleaning of the stirring blade 120 is more convenient, because if the sealing ring 140 is arranged in the stirring blade 120, the structure of the installation groove 1221 of the stirring blade 120 is complex, water and food residues are easily accumulated, and the stirring blade is easily decayed after a long time; the sealing ring 140 is arranged on the stirring shaft 130, the mounting groove 1221 of the stirring blade 120 has a simple structure, and can be washed clean with water, and meanwhile, the sealing ring 140 is exposed out of the stirring shaft 130, so that the sealing ring 140 can be washed from the outside, the structure of the sealing ring 140 cannot be damaged, and the service life of the sealing ring 140 can be prolonged.

In some embodiments, as shown in fig. 1 and 4, the stirring blade 120 is a metal stirring blade 120, the stopper 1223 is a metal ring-shaped piece, and the stopper 1223 is welded to an end surface of the opening of the mounting groove 1221. With the arrangement, the metal stirring blade 120 has the advantages of high structural strength, difficult deformation under stress, high safety and suitability for processing and production of food containers; through linking to each other stopper 1223 and stirring leaf 120 welding for joint strength between stopper 1223 and the stirring leaf 120 is high, is difficult for the pine to take off, and, assemble behind stopper 1223 and the welding of stirring leaf 120 for a part again, improved the wholeness of stirring subassembly, reduced spare part quantity, reduced the installation procedure, improved the installation effectiveness, make the installation of stirring subassembly more convenient and reliable.
