Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of drinking water equipment, concretely relates to a teapot. BACKGROUND

[0002] At present, the commonly used tea boiling pot on the market generally is that tea leaves are placed in a tea basket, and the tea basket is immersed in water to directly contact with water for tea soaking, but when the tea is boiled by the tea basket, the tea leaves directly contact with water, tea residue is formed in the tea, and the tea leaves are soaked in the tea for a long time, so that the taste of the tea is not good, and the use experience of the user is affected.

[0003] Based on the above problems, a tea extraction and health preserving pot with a tea steaming rack is disclosed in the prior art, which comprises a pot body, a heating control member, a tea extraction hourglass, a pot bottom and a pot cover, and an annular groove is arranged on the pot bottom; the tea extraction hourglass comprises a heating cavity cover, a tea storage funnel and a gas guide pipe, the opening end of the heating cavity cover is arranged opposite to the opening end of the tea storage funnel, and the two ends of the gas guide pipe are connected with the heating cavity cover and the tea storage funnel respectively; the tea leaves are placed on the tea storage funnel, so that the tea leaves do not directly contact with water, high-temperature steam is formed and collected by the heating cavity cover, the water-steam mixture formed by the high-temperature steam and water enters the tea storage funnel upward along the gas guide pipe and is sprayed on the tea leaves, that is, the tea leaves are soaked by relying on the spraying effect of the high-temperature water-steam mixture; the scheme does not form tea residue in the tea, and the taste of the tea is improved.

[0004] However, the tea extraction hourglass boiling scheme has the following disadvantages: although the tea extraction hourglass can soak the tea leaves by collecting high-temperature water-steam mixture, and does not form tea residue in the tea, the structure design of the bottom of the tea extraction hourglass abutting against the inner wall of the pot bottom requires the pressing force of the pot cover, and after a large amount of steam is generated, the bottom of the tea steaming rack cannot be timely supplied with water, so that the water supply and spraying effects of the whole tea steaming rack are affected, and when a large amount of steam is generated, the tea steaming rack is pushed upward, which causes the tea steaming rack to move up and down in the tea boiling pot and impact the bottom of the tea boiling pot, thereby producing noise and causing poor user experience.

[0005] Therefore, there is an urgent need for a scheme capable of improving the water supply and spraying effects while reducing the tea boiling noise. UTILITY MODEL CONTENTS

[0006] The technical problem to be solved by the utility model is to provide a tea pot to solve at least one of the above problems.

[0007] To solve the above technical problems, the utility model discloses the following technical scheme: a teapot, including the teapot body that is equipped with the teapot mouth, the tea steaming subassembly that is located in the teapot body and the heating assembly that is located at the bottom of teapot body, the tea steaming subassembly includes filter piece, gas collecting cover and gas guide pipe, the filter piece is installed at the teapot mouth, the gas collecting cover is located below the filter piece, the gas guide pipe is connected between the gas collecting cover and filter piece, to with the water vapor that the gas collecting cover collected is transmitted to the filter piece and is soaked tea leaf, the gas collecting cover includes the heat collection section of inner wall vertical extension, the gas collecting cover is suspended in the water containing cavity of the teapot body, to form the negative pressure compensation overflow gap between the bottom of heat collection section and the inner bottom wall of teapot body, the negative pressure compensation overflow gap is used to connect the internal space of water containing cavity and gas collecting cover.

[0008] The technical scheme has the following technical effects:

[0009] The utility model discloses the gas collecting cover is suspended in the teapot body, can make the lower end of the heat collection section of gas collecting cover not with the inner bottom wall of teapot body contact. Because the whole gas collecting cover is in contact with the inner bottom wall of teapot body, the water flow in the gas collecting cover is easily burned dry, the user cannot know in time, and need the user to open the kettle and take out the tea steaming rack to add water in the heating process, it is easy to cause scalding, therefore, the bottom of gas collecting cover and the inner bottom wall of teapot body have negative pressure compensation overflow gap, so that the water flow in the teapot can flow to the lower heat collection section through the negative pressure compensation overflow gap, to supplement the water flow in the lower part of gas collecting cover, ensure the spraying effect of tea steaming rack, and do not need to add water when the tea kettle boils, also convenient for the user to check the water amount in the tea kettle, when the water vapor in the teapot is more and the gas collecting cover is moved up and down by upwardly pushing, the gas collecting cover will not hit the inner bottom wall of teapot under the action of gravity, avoid the tea kettle to produce larger noise when brewing tea, improve the user's experience.

[0010] In the above-mentioned teapot, the heat collection section is located directly above the heating assembly, the inner diameter L of the gas collecting cover at the heat collection section is related to the diameter D of the heating assembly, the inner diameter L is in a positive proportional relationship with the height H of the negative pressure compensation overflow gap, and the ratio of the inner diameter L to the height H is between 3 and 80. The water flow near the heating assembly in the teapot warms up the fastest, so the heat collection section and the heating assembly are aligned in the vertical direction, so that the water vapor generated by the rapid warming of the water flow in this area can be collected by the gas collecting cover in large quantities, and the water vapor collection effect is good. At the same time, the larger the inner diameter of the gas collecting cover at the heat collection section, the larger the space at the bottom of the gas collecting cover. In this case, the height of the negative pressure compensation overflow gap needs to be increased to ensure better tea steaming effect. The inner diameter L corresponds to the diameter D of the heating assembly, so that the inner diameter L is adapted to the size of the heating assembly in the teapot, to balance the heating effect and the tea steaming effect.

[0011] In the tea kettle, the bottom of the heat collecting section is a ring structure to match the inner bottom wall to form a ring-shaped negative pressure compensation overflow gap, and the height H of the negative pressure compensation overflow gap satisfies 1mm≤H≤25mm. The steam tea effect is good, the negative pressure compensation overflow gap is not less than 1mm to avoid that the water flow on the outer periphery of the gas collecting cover cannot flow smoothly into the gas collecting cover, and the negative pressure compensation overflow gap is not more than 25mm to avoid that the gas collecting cover is too high to cause poor collection effect of the steam, and the negative pressure compensation overflow gap is a ring structure to uniformly supply water from all around, to maintain the water balance inside and outside the gas collecting cover, and to prevent insufficient steam or dry burning.

[0012] In the tea kettle, the gas collecting cover includes a gathering section arranged above the heat collecting section, the inner diameter of the gathering section gradually decreases from bottom to top, the lower end of the gas guide pipe is connected to the top of the gathering section, and the upper end of the gas guide pipe is fixed to the bottom of the filter. The constant inner diameter of the heat collecting section of the gas collecting cover can collect as much rising steam as possible, the gathering section can guide the rising steam from the heat collecting section to quickly gather in the gas guide pipe for upward transmission, to improve the steam tea efficiency and reduce the top motion of the steam to the gas collecting cover; and the lower end of the gas guide pipe is connected to the gathering section, and the upper end of the gas guide pipe is fixed to the bottom of the filter, so that when the user needs to use the steam tea assembly, the steam tea assembly is only needed to be placed in the kettle body, and when the filter is matched with the kettle opening to realize positioning, the steam tea assembly is completely installed to make the gas collecting cover suspended, and the user operation is convenient and simple.

[0013] In the tea kettle, the gathering section and the heat collecting section cooperate to form a steam chamber of the gas collecting cover, and the volume V1 of the negative pressure compensation overflow gap is related to the volume V2 of the steam chamber, and the ratio of V1 to V2 ranges from 1:3 to 1:12. By limiting the volume ratio of the steam chamber to the negative pressure compensation overflow gap, the water supply and the boiling pressure are balanced, and the water supply pressure and the boiling pressure of the steam tea assembly during work are balanced.

[0014] In the tea kettle, the gas guide pipe communicates the steam chamber and the bottom of the filter to transmit the steam generated in the steam chamber to the inside of the filter, the volume V3 of the gas guide pipe is related to the volume V2 of the steam chamber, and the ratio of V3 to V2 ranges from 1:5 to 1:20. By limiting the volume ratio of the steam chamber to the gas guide pipe, the spraying effect of the steam tea assembly is improved while maintaining a relatively stable boiling pressure.

[0015] In the tea kettle, the collection section is provided with a plurality of air holes, and the air holes longitudinally pass through the collection section.

[0016] In the tea kettle, the filter has a filter cavity for containing tea leaves, and the top of the air guide pipe penetrates the filter and extends into the filter cavity, so that the air outlet at the top of the air guide pipe is higher than the inner bottom surface of the filter cavity.

[0017] In the tea kettle, the top of the air guide pipe is provided with an air guide plate with an outer diameter larger than that of the air guide pipe, and an air gap is formed between the air guide plate and the air guide pipe. The water vapor flowing out of the top of the air guide pipe first moves upward, changes the flow path when encountering the blockage of the air guide plate, and flows into the air gap to enter the filter cavity on the side of the air gap to steam and soak the tea leaves. The water vapor is evenly dispersed in the filter cavity through the air gap, so that the tea leaves in the filter cavity can be evenly steamed, the tea steaming effect is good, and the outer diameter of the air guide plate is larger than that of the air guide pipe to block the water vapor flowing out of the air gap from rising directly as much as possible, that is, to reduce the water vapor that does not contact the tea leaves and rises directly as much as possible, and improve the utilization rate of water vapor.

[0018] In the tea kettle, the outer side wall of the air guide pipe is provided with a positioning rib, and the outer side wall of the air guide pipe is further provided with an elastic buffer, and the upper end of the elastic buffer is connected with the air guide plate, and the lower end of the elastic buffer is connected with the positioning rib. The positioning rib limits the vertical direction of the elastic buffer to support the elastic buffer and the air guide plate. The elastic buffer can adjust the height of the air guide plate and the height of the air gap. When the air pressure in the air guide pipe is greater than the weight of the air guide plate, the water vapor lifts the air guide plate upward to increase the height of the air gap. When the air pressure in the air guide pipe is reduced to be less than the weight of the air guide plate, the air guide plate reduces the height of the air gap under the pulling force of the elastic buffer. The variable height of the air gap makes the tea steaming assembly 200 more suitable for a wider range of applications.

[0019] The characteristics and advantages of the present application will be described in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF DRAWINGS

The tea steaming assembly 200 comprises a filter 210, a gas collecting cover 220 and a gas guide pipe 230, the filter 210 is installed at the kettle opening 110 for containing tea leaves, a plurality of filter holes are arranged on the bottom wall and the side wall of the filter 210, the gas collecting cover 220 is located below the filter 210, and the gas guide pipe 230 extends vertically to connect the gas collecting cover 220 and the filter 210, so that the lower end of the gas collecting cover 220 is suspended inside the kettle body 100, that is, the lower end of the gas collecting cover 220 does not contact the inner bottom wall of the kettle body 100, and a negative pressure compensation overflow gap 120 is formed between the bottom of the gas collecting cover 220 and the inner bottom wall of the kettle body 100. In use, water is poured into the kettle body 100, the highest water level is lower than the bottom of the filter 210, so that the tea leaves do not contact the water, then the tea leaves are put into the filter 210, and the tea steaming assembly 200 is put into the kettle body 100, when the heating assembly 300 works, the heat generated by the heating assembly 300 is conducted into the kettle body 100 to heat the water inside the kettle body 100, the high-temperature steam generated after the water is heated is collected by the gas collecting cover 220, then rises to the filter 210 through the gas guide pipe 230, the high-temperature steam in the filter 210 contacts the tea leaves to steam and soak the tea leaves, condenses and forms tea water, and the tea water falls into the tea water below the filter 210 through the filter holes on the filter 210 under the action of gravity, so as to avoid that the tea leaves contact the water outside the filter 210 for a long time to cause tea residue in the tea water drunk by the user and affect the taste.

[0035] The utility model discloses a steam collecting cover 220 is suspended in the kettle body 100, the lower end of steam collecting cover 220 does not contact with the inner bottom wall of kettle body 100, when the steam in kettle body 100 is more and steam collecting cover 220 is moved up and down by steam collecting cover 220, steam collecting cover 220 will not hit the inner bottom wall of kettle body 100 under the action of gravity, avoid the larger noise of teapot when brewing tea. Because steam collecting cover 220 and the inner bottom wall of kettle body 100 abut, steam collecting cover 220 is easy to appear the condition of water flow dry, user cannot know in time, and need user to open the kettle and take out the tea steaming frame to add water in the heating process, it is easy to cause scald, therefore, the bottom of steam collecting cover 220 and the inner bottom wall of kettle body 100 have negative pressure compensation overflow gap 120, when steam collecting cover 220 is in negative pressure state, the water flow in the water containing cavity of kettle body 100 can be continuously supplied to the lower part of steam collecting cover 220 through negative pressure compensation overflow gap 120 to keep the water balance of steam collecting cover 220, guarantee the water supply effect and the spraying effect of tea steaming frame when brewing tea, prevent the steam volume from being insufficient or dry burning, need not add water when the tea kettle is boiling, also convenient for user to check the water amount in the tea kettle, improve the use experience of user.

[0036] As Figure 3 As shown in the embodiment, steam collecting cover 220 is inverted funnel-shaped, so that steam collecting cover 220 can collect as much steam in kettle body 100 as possible, the lower end of gas guide pipe 230 is connected with steam collecting cover 220, and the upper end of gas guide pipe 230 is fixed on the bottom of filter piece 210, so that when user needs to use tea steaming assembly 200, only needs to put tea steaming assembly 200 into kettle body 100, when filter piece 210 is matched with kettle mouth 110 to realize positioning, the whole tea steaming assembly 200 is installed, so that steam collecting cover 220 is suspended, and user operation is convenient and simple. Steam collecting cover 220 in the embodiment includes heat collecting section 221 and folding section 222, heat collecting section 221 is arranged at the lower end of folding section 222, the inner wall of heat collecting section 221 is vertically arranged, so that the inner diameter of heat collecting section 221 remains constant from bottom to top, and the inner diameter of folding section 222 gradually decreases from bottom to top, the constant inner diameter of heat collecting section 221 of steam collecting cover 220 can collect as much rising steam as possible, folding section 222 can guide the steam rising from heat collecting section 221, so that a large amount of steam is quickly gathered in gas guide pipe 230 to be transmitted upward, which improves tea steaming efficiency and reduces the upward movement of steam to steam collecting cover 220.

[0037] The gas collecting cover 220 in the embodiment is arranged directly above the heating assembly 300, and the center axis of the gas collecting cover 220 and the heating assembly 300 coincide. Because the water flow near the heating assembly 300 in the kettle 100 is heated most quickly, the gas collecting cover 220 is aligned with the heating assembly 300 in the vertical direction, so that the water vapor generated by the rapid heating of the water flow in this area can be collected by the gas collecting cover 220 in a large amount, and the collection effect of the water vapor is good.

[0038] According to the regulations, the height of the negative pressure compensation overflow gap 120 in the embodiment is H, and the inner diameter of the gas collecting cover 220 at the heat collecting section 221 is L, L and H are in a positive proportional relationship, and the specific proportional coefficient can be set to be between 3-80, in which interval the water replenishment effect of the tea steaming cover is best, and sufficient water vapor generation is ensured. The inner diameter L is also related to the diameter D of the heating assembly. The diameter D of the heating device is a certain fixed value, which is used to determine the specific values of the inner diameter L and the height H, that is, the larger the inner diameter of the heat collecting section 221, the greater the height of the negative pressure compensation overflow gap 120, so as to ensure the tea steaming effect. At the same time, the projection of the inner circle of the heating assembly on the horizontal plane needs to be located in the projection of the gas collecting cover on the horizontal plane, so as to ensure the heating effect. Therefore, the inner diameter L needs to be limited according to the diameter D of the heating assembly.

[0039] Preferably, the bottom of the heat collecting section is a ring structure to form a ring-shaped negative pressure compensation overflow gap with the inner bottom wall. The height of the negative pressure compensation overflow gap 120 is H. The negative pressure compensation overflow gap is designed to be a ring structure, so that the gas collecting cover can uniformly replenish water from all around, facilitate the maintenance of water balance inside and outside the gas collecting cover, prevent the situation of insufficient steam caused by insufficient water replenishment in time, or the situation of dry burning caused by the internal water evaporation too fast and the water in the water containing cavity cannot be replenished in time, and at the same time meet 1mm≤H≤25mm, so that the tea steaming effect is good. The negative pressure compensation overflow gap 120 is not less than 1mm, so as to avoid that the negative pressure compensation overflow gap 120 is too small to cause the water flow in the water containing cavity to flow smoothly into the gas collecting cover 220. The negative pressure compensation overflow gap 120 is not greater than 25mm, so as to avoid that the gas collecting cover 220 is too high to cause poor collection effect of the gas collecting cover 220 on the water vapor. The value of H can be 1mm, 3mm, 5mm, 7mm, 9mm, 10mm, 11mm, 13mm, 15mm, 17mm, 19mm, 20mm, 21mm, 23mm, 25mm.

[0040] In the embodiment, the converging section 222 and the heat collecting section 221 cooperate to form a steam cavity of the gas collecting cover 220, the volume V1 of the negative pressure compensation over-flow gap is related to the volume V2 of the steam cavity, and the ratio of V1 to V2 ranges from 1:3 to 1:12. That is, the volume V2 of the negative pressure compensation over-flow gap 120 is defined by the volume V1 of the steam cavity, and the specific ratio range can be set to 1:3 to 1:12. The volume V2 of the steam cavity is determined by the inner diameter L and the shape and height of the converging section 222, and is a fixed value after the tea brewing assembly 200 is formed. At this time, the specific size of the volume V1 of the negative pressure compensation over-flow gap 120 can be determined by the above-mentioned preset ratio range to achieve the pressure balance of the boiling pressure in the gas collecting cover 220 and the water supplementing pressure, prevent dry burning, and effectively output high-temperature steam to the guide air pipe 230. The volume V1 is determined by the bottom area of the heat collecting section 221 and the height H of the negative pressure compensation over-flow gap 120. In the embodiment, the bottom area and the height H of the heat collecting section 221 can be synchronously set according to the value condition of the height H and the specific size of the volume V1.

[0041] Specifically, the guide air pipe 230 is connected to the bottom of the steam cavity and the filter 210 to transmit the steam generated in the steam cavity to the inside of the filter 210. The volume V3 of the guide air pipe 230 is related to the volume V2 of the steam cavity, and the ratio of V3 to V2 ranges from 1:5 to 1:20. In the embodiment, the volume V3 of the guide air pipe 230 is related to the volume V2 of the steam cavity to maintain a relatively stable boiling pressure and ensure the spraying effect of the tea brewing assembly 200, that is, to prevent the spraying pressure of the high-temperature steam upward from being too small due to the excessively large volume V3 of the guide air pipe 230.

[0042] As shown in Figure 3 The converging section 222 is provided with a plurality of air holes 2221 which longitudinally penetrate the converging section 222. When the internal pressure of the gas collecting cover 220 is increased due to excessive steam, part of the steam can be discharged from the gas collecting cover 220 through the air holes 2221 to prevent the gas collecting cover 220 from being lifted upward due to the excessive internal pressure, ensure the stability of the gap between the gas collecting cover 220 and the inner bottom wall of the kettle body 100, and further ensure the stable collection of steam by the gas collecting cover 220.

[0043] In the embodiment, as shown in Figure 2As shown, the filter 210 has a filter cavity 211 for containing tea leaves, and the top of the air guide pipe 230 extends into the filter cavity 211 through the bottom wall of the filter 210, so that the air outlet at the top of the air guide pipe 230 is higher than the inner bottom surface of the filter cavity 211, thereby preventing the tea leaves in the filter cavity 211, especially the tea leaves expanded by absorbing water vapor, from blocking the air outlet at the top of the air guide pipe 230, ensuring that the water vapor in the air guide pipe 230 can smoothly enter the filter cavity 211, achieving good tea steaming effect, and preventing the water vapor from gathering in the air collecting cover 220 to cause excessive air pressure.

[0044] In this embodiment, the air guide plate 232 is arranged at the top of the air guide pipe 230, and the air guide plate 232 is horizontally arranged, and the air gap 233 is formed between the bottom surface of the air guide plate 232 and the top of the pipe wall of the air guide pipe 230. The water vapor flowing out of the top of the air guide pipe 230 first moves upward, and when the water vapor encounters the blockage of the air guide plate 232, the flow path changes and flows to the air gap 233 on the periphery to enter the filter cavity 211 on the periphery of the air gap 233 to steam and soak the tea leaves. The water vapor is uniformly dispersed in the filter cavity 211 through the air gap 233, so that the tea leaves in the filter cavity 211 can be uniformly steamed, achieving good tea steaming effect. The outer diameter of the air guide plate 232 is greater than the outer diameter of the air guide pipe 230 to as far as possible block the water vapor flowing out of the air gap 233 from directly rising upward, that is, to as far as possible reduce the water vapor that directly rises upward without contacting the tea leaves, thereby improving the utilization rate of the water vapor. The air guide plate 232 in this embodiment can be a flat plate or an arc-shaped plate that is upwardly arched. In order to further enhance the air guiding effect of the air guide plate 232, the air guide plate 232 is preferably arranged in a structure in which the edge thereof is downwardly bent, so that the water vapor passing through the air gap 233 is guided by the edge of the air guide plate 232 to flow toward the tea leaves on the inner bottom wall of the filter cavity 211, thereby fully utilizing the water vapor and achieving good steaming effect on the tea leaves.

[0045] The outer sidewall of the air guide pipe 230 is provided with the positioning protruding ribs 231 that surround the air guide pipe 230, and the upper end of the air guide plate 232 is connected to the elastic buffer 234, and the lower end of the elastic buffer 234 is connected to the positioning protruding ribs 231. The positioning protruding ribs 231 limit the vertical position of the elastic buffer 234 to support the elastic buffer 234 and the air guide plate 232. The height of the air guide plate 232 and the height of the air gap 233 can be adjusted by the elastic buffer 234. When the air pressure in the air guide pipe 230 is greater than the weight of the air guide plate 232, the water vapor pushes the air guide plate 232 upward to increase the height of the air gap 233. When the air pressure in the air guide pipe 230 is reduced to be less than the weight of the air guide plate 232, the air guide plate 232 is pulled downward by the elastic force of the elastic buffer 234 to reduce the height of the air gap 233. The variable height of the air gap 233 makes the tea steaming assembly 200 more widely applicable.
