Description

Technical Field

[0001] The utility model belongs to the field of drinking water equipment, and particularly relates to a teapot. Background Art

[0002] At present, there are two types of teapots commonly used on the market. One is that the tea leaves are in the tea basket, and the tea basket is in direct contact with water to soak the tea leaves; the other is that the tea leaves are on the tea steaming rack. The tea leaves are not in direct contact with water, but the steam is collected by the tea steaming rack, and then the tea leaves are soaked by high-temperature steam.

[0003] However, both of the above-mentioned teapots currently have disadvantages. When boiling tea in a tea basket, the tea leaves are in direct contact with water, and tea residues will be formed in the tea, affecting the taste of the tea. Although the tea steaming rack can soak the tea leaves by collecting steam and will not form tea residues in the tea, the tea steaming rack is staggered with the heating component, which makes the steam collection effect of the tea steaming rack poor for the area of ​​the teapot that heats up faster (i.e., the area corresponding to the heating component), resulting in low tea steaming efficiency and long tea steaming time. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a teapot to solve at least one of the above problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a teapot, comprising a pot body provided with a pot cavity, a tea steaming component provided in the pot cavity, and a heating component provided at the bottom of the pot body, the tea steaming component comprising a filter, an air collecting hood, and an air guide tube, the filter being installed at the pot mouth at the top of the pot cavity, the air collecting hood being located below the filter, the air guide tube being connected between the air collecting hood and the filter to transfer the water vapor collected by the air collecting hood to the filter for soaking tea leaves, the heating component comprising an annular heating element installed at the bottom of the pot body, the inner ring diameter of the annular heating element being smaller than the inner diameter of the bottom of the air collecting hood, so that the projection of the inner ring of the annular heating element on the horizontal plane is located within the projection of the air collecting hood on the horizontal plane. This technical solution has the following technical effects:

[0006] The utility model installs the annular heating element at the bottom of the kettle body and sets the inner diameter of the bottom of the air collecting hood to be larger than the inner diameter of the bottom of the annular heating element, so that the projection of the inner circle of the annular heating element on the horizontal plane is completely located within the projection of the air collecting hood on the horizontal plane, that is, the air collecting hood and the heating component are aligned up and down, and the air collecting hood partially covers or completely covers the water flow inside the kettle body directly above the annular heating element. Because the water flow in the areas above and below the annular heating element in the kettle body has the fastest temperature rise and generates the largest amount of water vapor, the projection of the inner circle of the annular heating element on the horizontal plane is set to be entirely located within the projection of the gas collecting hood on the horizontal plane, so that the gas collecting hood in the kettle body can partially or completely cover the water flow in the area with the fastest temperature rise, so that when heating, the first water vapor generated in the kettle body and the subsequent large amount of water vapor can be collected as much as possible by the gas collecting hood, and transmitted to the filter element for steaming and soaking the tea leaves. The water vapor collection effect is good, the tea steaming effect is improved, and a large amount of water vapor is avoided from bypassing the gas collecting hood and being unable to be transmitted to the filter element by the air duct, resulting in waste of water vapor, shortening the tea steaming time, and improving the tea steaming efficiency.

[0007] In the aforementioned teapot, the gas collecting hood is shaped like an inverted funnel, and the central axis of the gas collecting hood is coaxial with the central axis of the annular heating element. The inverted funnel shape of the gas collecting hood allows the gas collecting hood to collect as much water vapor as possible from the teapot body and quickly transfer the water vapor to the air duct. The coaxial arrangement of the central axis of the annular heating element and the central axis of the gas collecting hood improve the gas collecting effect of the gas collecting hood and enhance the efficiency of tea steaming.

[0008] In the above-mentioned teapot, the outer diameter of the annular heating element is N, and the inner diameter of the bottom of the gas hood is A, satisfying A<N. Because if the gas hood fully covers the annular heating element, the water vapor generated in this area will all be collected by the gas hood, and the air duct will not have time to transmit all the water vapor to the filter element, which will cause a large amount of water vapor to accumulate in the gas hood, causing the pressure inside the gas hood to be too high to push the gas hood upward, and the tea steaming component will vibrate up and down in the pot body, causing a lot of noise. By setting the bottom of the gas hood to only cover the part of the annular heating element close to the inner circle, the gas hood can collect enough water vapor to improve the tea steaming effect, and can also avoid the pressure inside the gas hood being too high to push the gas hood upward, thereby improving the user experience.

[0009] In the aforementioned teapot, the air collection hood includes a heat collection section extending vertically from its inner wall and a gathering section located above the heat collection section. The inner diameter of the gathering section gradually decreases from bottom to top. The heat collection section of the air collection hood maintains a constant inner diameter, thereby collecting as much rising water vapor as possible. The gathering section guides the water vapor rising from the heat collection section, allowing a large amount of water vapor to be quickly gathered into the air guide pipe for upward transmission. This improves tea steaming efficiency while reducing the impact of water vapor on the air collection hood.

[0010] In the above-mentioned teapot, the area of ​​the outer wall of the heat collection section is D, and the projected area of ​​the gas collecting hood on the horizontal plane is E, which satisfies 0.2<D / E<0.3. Because, if D / E is not greater than 0.2, then in this case, the height of the outer wall of the solar collection section is too small, and the inner diameter of the solar collection section is too large. At this time, the internal space of the solar collection section is small, the gas collection time in the solar collection section is short and the gas collection is fast, resulting in high steam pressure in the gas collection hood, and steam can easily pass through the tea steaming component to push open the lid of the pot, scalding the user; if D / E is not less than 0.3, then in this case, the height of the outer wall of the solar collection section is too large, and the inner diameter of the solar collection section is too small. At this time, the internal space of the solar collection section is large, the gas collection time in the solar collection section is long and slow, which leads to a long tea steaming time and a poor user experience; therefore, maintaining the ratio of the area D of the outer wall of the solar collection section to the projected area E of the gas collection hood on the horizontal plane between 0.2 and 0.3 can improve the tea steaming efficiency while avoiding steam from passing through the tea steaming component to push open the lid of the pot, thereby ensuring user safety.

[0011] In the aforementioned teapot, the gathering section is provided with a plurality of vent holes, which are arranged longitudinally through the gathering section. When excessive water vapor in the gas collecting hood causes the internal pressure to rise, some of the water vapor can be discharged from the gas collecting hood through the vent holes, thereby preventing the gas collecting hood from being lifted upward due to excessive pressure, thereby ensuring that the gas collecting hood can stably collect water vapor.

[0012] In the aforementioned teapot, the teapot body includes side panels and a bottom panel that enclose the pot cavity. The bottom panel is a heat-conducting plate, and the annular heating element is attached to the bottom of the heat-conducting plate. Heat from the annular heating element is quickly transferred to the heat-conducting plate, which uniformly heats the water in the central area of ​​the teapot body. This allows the water in the central area of ​​the teapot, corresponding to the gas collecting hood, to quickly heat up to a vapor-generating temperature, thereby improving tea steaming efficiency.

[0013] In the aforementioned teapot, the air hood is secured to the filter element via an air guide tube, such that its lower end is suspended within the pot cavity, forming a water-passing gap between the bottom of the air hood and the inner bottom wall of the pot cavity. The lower end of the air hood does not contact the inner bottom wall of the pot body. When water vapor within the pot body pushes the air hood upward, causing it to move up and down, the air hood does not strike the inner bottom wall of the pot body due to gravity, thereby preventing the teapot from generating loud noises during tea brewing. Because when the air collecting hood abuts against the inner bottom wall of the kettle body, the water in the air collecting hood is likely to dry up, and the user cannot be informed in time. Moreover, the user is required to open the kettle and take out the tea steaming rack to add water during the heating process, which can easily cause burns. Therefore, there is a water gap between the bottom of the air collecting hood and the inner bottom wall of the kettle body, so that the water in the kettle body can flow continuously to the lower part of the air collecting hood through the water gap to replenish the water flow in the lower part of the air collecting hood. There is no need to add water when the teapot is boiling, and it is also convenient for the user to check the amount of water in the teapot, thereby improving the user experience.

[0014] In the aforementioned teapot, the height of the water gap is H, and the inner diameter of the bottom of the gas hood is A. H and A are positively correlated. The larger the internal space of the gas hood, the more steam it collects and the higher the heat it accumulates. Consequently, when the water in the pot boils, the overall vibration of the tea steaming frame increases. Therefore, a larger inner diameter of the heat collection section requires a larger water gap height to reduce vibration noise and ensure more timely water replenishment to the gas hood, ensuring optimal tea steaming results.

[0015] In the teapot, the height of the water gap is H, satisfying 1mm≤H≤25mm. The water gap is not less than 1mm to prevent water from flowing smoothly from the outer periphery of the gas hood into the gas hood due to the water gap being too small. The water gap is not greater than 25mm to prevent the gas hood from being too high, resulting in poor water vapor collection, thereby ensuring good tea steaming effect.

[0016] The features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention provides a teapot, comprising a pot body with a pot cavity, a tea steaming assembly disposed in the pot cavity, and a heating assembly disposed at the bottom of the pot body, wherein the tea steaming assembly comprises a filter, an air collecting hood, and an air guide tube, wherein the filter is mounted at the pot mouth at the top of the pot cavity, the air collecting hood is located below the filter, and the air guide tube is connected between the air collecting hood and the filter to transmit water vapor collected by the air collecting hood to the filter for soaking tea leaves, and the heating assembly comprises an annular heating element mounted at the bottom of the pot body, wherein the inner diameter of the annular heating element is smaller than the inner diameter of the bottom of the air collecting hood, so that the projection of the inner ring of the annular heating element on a horizontal plane is located within the projection of the air collecting hood on the horizontal plane. The present invention achieves this by mounting the annular heating element at the bottom of the pot body and setting the inner diameter of the bottom of the air collecting hood to be larger than the inner diameter of the bottom of the annular heating element, so that the projection of the inner ring of the annular heating element on a horizontal plane is entirely located within the projection of the air collecting hood on the horizontal plane, i.e., the air collecting hood is aligned with the heating assembly vertically, and the air collecting hood partially or completely covers the water flow inside the pot body directly above the annular heating element. Because the water flow in the areas above and below the annular heating element in the kettle body has the fastest temperature rise and generates the largest amount of water vapor, the projection of the inner circle of the annular heating element on the horizontal plane is set to be entirely located within the projection of the gas collecting hood on the horizontal plane, so that the gas collecting hood in the kettle body can partially or completely cover the water flow in the area with the fastest temperature rise, so that when heating, the first water vapor generated in the kettle body and the subsequent large amount of water vapor can be collected as much as possible by the gas collecting hood, and transmitted to the filter element for steaming and soaking the tea leaves. The water vapor collection effect is good, the tea steaming effect is improved, and a large amount of water vapor is avoided from bypassing the gas collecting hood and being unable to be transmitted to the filter element by the air duct, resulting in waste of water vapor, shortening the tea steaming time, and improving the tea steaming efficiency.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.

[0030] Example 1:

[0031] A teapot, such as Figures 1 to 2 As shown, the tea steaming assembly includes a kettle body 100, a tea steaming assembly, and a heating assembly. The top of the kettle body 100 is provided with a spout 120. The tea steaming assembly is arranged inside the kettle body 100. The heating assembly includes an annular heating element 300. The annular heating element 300 is installed at the bottom of the kettle body 100 to heat the water in the kettle body 100 by heating the kettle body 100. The tea steaming assembly includes a filter 210, an air collecting cover 220, and an air guide tube 230. The filter 210 is installed at the spout 120 for accommodating tea leaves. The bottom wall and side walls of the filter 210 are provided with multiple filter holes. The air collecting cover 220 is located below the filter 210. The air guide tube 230 extends vertically to connect the air collecting cover 220 and the filter 210. The annular heating element 300 is annular in shape, and the inner diameter of the annular heating element 300 is smaller than the inner diameter of the bottom of the gas collecting cover 220, that is, the projection of the inner circle of the annular heating element 300 on the horizontal plane is entirely located within the projection of the gas collecting cover 220 on the horizontal plane.

[0032] During use, water is poured into the kettle body 100, and the highest water level is lower than the bottom of the filter 210, so that the tea leaves do not come into contact with the water. Then, tea leaves are put into the filter 210, and the tea steaming component is put into the kettle body 100. When the heating component is working, the heat generated by it is conducted to the kettle body 100 to heat the water in the kettle body 100. The high-temperature water vapor generated after the water is heated is collected by the gas collecting hood 220, and then rises to the filter 210 through the air guide pipe 230. The high-temperature water vapor in the filter 210 contacts the tea leaves to steam and soak the tea leaves, condenses and forms tea water. Under the action of gravity, the tea water falls into the tea water below the filter 210 through the filter holes on the filter 210 to avoid long-term contact between the tea leaves and the water outside the filter 210, which may cause tea residue to be produced in the tea drunk by the user and affect the taste.

[0033] The utility model installs the annular heating element 300 at the bottom of the kettle body 100 and sets the inner diameter of the bottom of the air collecting hood 220 to be larger than the inner diameter of the bottom of the annular heating element 300, so that the projection of the inner circle of the annular heating element 300 on the horizontal plane is completely located within the projection of the air collecting hood 220 on the horizontal plane, that is, the air collecting hood 220 and the annular heating element 300 are aligned up and down, and the air collecting hood 220 partially covers or completely covers the water flow inside the kettle body 100 directly above the annular heating element 300. Because the water flow in the area corresponding to the upper and lower areas of the annular heating element 300 in the kettle body 100 has the fastest temperature rise and generates the largest amount of water vapor, the projection of the inner circle of the annular heating element 300 on the horizontal plane is set to be entirely located within the projection of the gas collecting hood 220 on the horizontal plane, so that the gas collecting hood 220 in the kettle body 100 forms partial or complete coverage of the water flow in the area with the fastest temperature rise, so that when heating, the water vapor first generated in the kettle body 100 and the subsequent large amount of water vapor can be collected as much as possible by the gas collecting hood 220, and transmitted to the filter element 210 for steaming and soaking the tea leaves. The water vapor collection effect is good, the tea steaming effect is improved, and a large amount of water vapor is avoided from bypassing the gas collecting hood 220 and being unable to be transmitted to the filter element 210 by the air duct 230, resulting in waste of water vapor, shortening the tea steaming time, and improving the tea steaming efficiency.

[0034] In this embodiment, the lower end of the air guide tube 230 is connected to the air collecting hood 220, and the upper end of the air guide tube 230 is fixed to the bottom of the filter element 210, so that when the user needs to use the tea steaming component, he only needs to put the tea steaming component into the pot body 100. When the filter element 210 cooperates with the pot mouth 120 to achieve positioning, the entire tea steaming component is installed. The air collecting hood 220 is in the shape of an inverted funnel, so that the air collecting hood 220 can collect as much water vapor as possible in the pot body 100 and quickly transfer the water vapor to the air guide tube 230. Preferably, the central axis of the annular heating element 300 is coaxially arranged with the central axis of the air collecting hood 220, so that the air collecting hood 220 has a better collection effect on water vapor and improves the efficiency of tea steaming.

[0035] The air collecting hood 220 in this embodiment includes a heat collecting section 221 and a gathering section 222. The heat collecting section 221 is provided at the lower end of the gathering section 222. The inner wall of the heat collecting section 221 is vertically extended so that the inner diameter of the heat collecting section 221 remains constant from bottom to top, and the inner diameter of the gathering section 222 gradually decreases from bottom to top. The heat collecting section 221 of the air collecting hood 220 has a constant inner diameter and can collect the rising water vapor as much as possible. The gathering section 222 can guide the water vapor rising from the heat collecting section 221, so that a large amount of water vapor is quickly gathered into the air guide pipe 230 for upward transmission, thereby improving the tea steaming efficiency and reducing the impact of water vapor on the air collecting hood 220. Figure 2 As shown, a plurality of air vents 2221 are provided on the gathering section 222, and the air vents 2221 are arranged longitudinally through the gathering section 222, so that when there is too much water vapor in the gas collecting hood 220 and its internal pressure increases, part of the water vapor can be discharged from the gas collecting hood 220 through the air vents 2221, avoiding excessive pressure in the gas collecting hood 220 and pushing the gas collecting hood 220 upward, thereby ensuring stable collection of water vapor by the gas collecting hood 220.

[0036] In this embodiment, it is stipulated that the area of ​​the outer wall of the heat collecting section 221 is D, and the projected area of ​​the gas collecting hood 220 on the horizontal plane is E, which satisfies 0.2<D / E<0.3. Because, if D / E is not greater than 0.2, then in this case, the height of the outer wall of the heat collecting section 221 is too small, and at the same time the inner diameter of the heat collecting section 221 is too large. At this time, the internal space of the heat collecting section 221 is small, the gas collection time in the heat collecting section 221 is short and the gas collection is fast, resulting in a high steam pressure in the gas collecting hood 220, and the steam can easily pass through the tea steaming component to open the pot lid and scald the user; if D / E is not small If the area D of the outer wall of the heat collecting section 221 is greater than 0.3, then in this case, the height of the outer wall of the heat collecting section 221 is too large, and the inner diameter of the heat collecting section 221 is too small. At this time, the internal space of the heat collecting section 221 is large, and the gas collection time in the heat collecting section 221 is long and slow, which leads to a long tea steaming time and a poor user experience. Therefore, maintaining the ratio of the area D of the outer wall of the heat collecting section 221 to the projected area E of the gas collecting hood 220 on the horizontal plane between 0.2 and 0.3 can improve the tea steaming efficiency while preventing steam from pushing open the pot lid through the tea steaming component, thereby ensuring the safety of users.

[0037] In this embodiment, if Figure 1As shown, the outer diameter of the annular heating element 300 is N, and the inner diameter of the bottom of the gas collecting hood 220 is A, satisfying A<N, that is, the bottom of the gas collecting hood 220 only covers the portion of the annular heating element 300 close to the inner circle. Because if the gas collecting hood 220 fully covers the annular heating element 300, the water vapor generated in this area will be collected by the gas collecting hood 220, and the air guide 230 will not have time to transmit all the water vapor to the filter element 210, which will cause a large amount of water vapor to accumulate in the gas collecting hood 220, causing the pressure in the gas collecting hood 220 to be too high to push the gas collecting hood 220 upward, and the tea steaming component will vibrate up and down in the pot body 100, making a lot of noise. By setting the bottom of the gas collecting hood 220 to only cover the portion of the annular heating element 300 close to the inner circle, the gas collecting hood 220 can collect enough water vapor to improve the tea steaming effect, and can also avoid the pressure in the gas collecting hood 220 to be too high to push the gas collecting hood 220 upward, thereby improving the user experience.

[0038] The kettle body 100 includes a side panel 140 and a bottom panel 150, which together form a kettle cavity 110 for containing tea. The bottom panel 150 in this embodiment is a heat-conducting plate made of metal, which has the function of quickly conducting heat. The annular heating element 300 is attached to the bottom of the heat-conducting plate and is coaxially arranged with the heat-conducting plate. The heat of the annular heating element 300 can be quickly transferred to the heat-conducting plate, and the water flow in the central area of ​​the kettle body 100 is evenly heated through the heat-conducting plate, so that the water flow in the central area of ​​the kettle body 100 corresponding to the gas collecting hood 220 is quickly heated to the temperature for generating water vapor, thereby improving the efficiency of tea steaming.

[0039] The gas collecting hood 220 in this embodiment is fixed to the filter element 210 via an air guide tube 230, so that the lower end of the gas collecting hood 220 is suspended in the pot cavity 110, and a water-passing gap 130 is formed between the bottom of the gas collecting hood 220 and the inner bottom wall of the pot cavity 110. By suspending the gas collecting hood 220 in the pot body 100, the lower end of the gas collecting hood 220 does not contact the inner bottom wall of the pot body 100. When the water vapor in the pot body 100 is large and pushes the gas collecting hood 220 upward, causing the gas collecting hood 220 to move up and down, the gas collecting hood 220 will not hit the inner bottom wall of the pot body 100 under the action of gravity, thereby preventing the teapot from generating loud noise when brewing tea. Because when the air collecting hood 220 abuts against the inner bottom wall of the kettle body 100, the water in the air collecting hood 220 may easily dry up, and the user cannot be informed in time, and the user needs to open the kettle and take out the tea steaming rack to add water during the heating process, which may easily cause burns. Therefore, there is a water gap 130 between the bottom of the air collecting hood 220 and the inner bottom wall of the kettle body 100, so that the water in the kettle body 100 can flow continuously to the lower part of the air collecting hood 220 through the water gap 130 to replenish the water flow in the lower part of the air collecting hood 220. There is no need to add water when the teapot is boiling water, which is also convenient for the user to check the amount of water in the teapot, thereby improving the user experience.

[0040] In this embodiment, the height of the water gap 130 is H, and the inner diameter of the bottom of the gas hood 220 is A. H and A are positively correlated. The larger the internal space of the gas hood 220, the greater the amount of steam it collects and the higher the heat it accumulates. Consequently, when the water in the kettle body 100 boils, the greater the vibration of the entire tea steaming frame. Therefore, when the inner diameter of the heat collecting section 221 is larger, the height of the water gap 130 needs to be larger to reduce the noise generated by vibration and ensure more timely water replenishment into the gas hood 220, thereby ensuring a good tea steaming effect. Preferably, 1mm≤H≤25mm, with the water gap 130 being no less than 1mm to prevent the water flow from the outer periphery of the gas hood 220 from being unable to flow smoothly into the gas hood 220 due to the water gap 130 being too small. The water gap 130 is no greater than 25mm to prevent the gas hood 220 from being too high, resulting in poor water vapor collection by the gas hood 220, thereby ensuring a good tea steaming effect. The value of H can be 1mm, 2mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, or 25mm.

[0041] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
