Description

Technical Field

[0001] The present invention relates to the field of electrical appliances, in particular to an automatic teapot. Background Art

[0002] Since the electric tea kettle in the prior art boils water in the container to form a large amount of gas in the cover, the water in the cover is moved upward by pressure to the tea basket assembly for spraying, thereby making tea. For example, the tea maker described in patent application CN201010550290.9 has a tea strainer assembly provided in the tea kettle, wherein a tea basket is provided on the upper part of the tea strainer assembly, and a mesh is provided at the bottom of the tea basket for placing tea leaves in the tea basket. An upper water pipe is provided in the middle of the tea strainer assembly, and the upper end of the upper water pipe extends into the interior of the tea basket. An inverted funnel is provided at the lower part of the upper water pipe, and a plurality of leakage holes are provided on the side of the bottom of the funnel. When the water boils, water vapor bubbles are formed in the funnel, and the bubbles gradually rise. The bubbles push the liquid in the upper water pipe up to reach the tea basket, spraying and brewing the tea leaves in the tea basket. However, this technology cannot achieve spray brewing with water temperatures between 80°C and 95°C. It cannot achieve precise temperature control for tea varieties such as green tea and black tea that require precise temperature control for brewing. That is, this technical solution cannot control the temperature of tea brewing and can only use boiling water for brewing. It cannot adapt to different function options, such as black tea, green tea, ginger tea, flower tea, coffee, etc., which require different preparation temperatures.

[0003] Another existing technology is a brewing device described in application number CN108814294A, which transports water in the container to the tea basket through a spiral technical solution. The screw structure of this technical solution is complex, the screw occupies a large space in the pot body, the capacity of the container itself to hold liquid is reduced, and the experience effect is poor. Summary of the Invention

[0004] To address the technical issues of existing tea makers, such as uncontrollable temperature or time, unable to achieve a variety of tea-brewing effects, or complex water-feeding structures that affect overall aesthetics, a new tea-brewing technical solution is provided. An air pump is used to pump air from the bottom of the container, causing the liquid to move upward into the tea basket assembly. This not only solves the problem of being able to feed water at any temperature, but also expands the adjustable water-feeding temperature range, increasing functional diversity. Furthermore, the air inlet is located at the bottom of the container, essentially flush with the bottom surface, improving the aesthetics of the pot and facilitating cleaning. Furthermore, when the tea basket assembly is removed from the container, the pot can be used as a regular health-preserving pot, and can also be used to intake air during the brewing function to prevent the bottom from becoming sticky.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automatic tea brewing pot, comprising a pot body comprising a container for holding liquid and a tea basket assembly provided at an upper portion of the container; a conveying device provided in the container, the conveying device comprising a water guide pipe provided at an upper portion and a cover provided at a lower portion, the upper end of the water guide pipe being communicated with an inner cavity of the tea basket assembly, the cover cooperating with the bottom wall of the container to form a steam cavity; an air pump assembly, the air pump assembly delivering the liquid in the container into the tea basket assembly via the conveying device for brewing the brewing substance in the tea basket assembly; the steam cavity being communicated with the container via a first through hole on the cover, a second through hole being provided on the bottom wall of the container, the cover being provided above the second through hole, the steam cavity being communicated with the air pump assembly via the second through hole.

[0006] The present invention is further configured as follows: the air pump assembly includes an air pump, a vent pipe and a control valve, one end of the vent pipe is connected to the second through hole, and the other end is connected to the air pump, and the control valve is arranged at the second through hole to control the connection between the vent pipe and the steam cavity.

[0007] The present invention is further configured such that: the control valve is a one-way valve. When the air pump is turned on, the gas squeezes the one-way valve to connect the vent pipe with the steam cavity. When the air pump is closed, the one-way valve closes the second through hole.

[0008] The present invention is further configured as follows: the one-way valve is a silicone valve, the silicone valve is provided with a breathable portion and a mounting portion, the breathable portion is provided with a cutout, in a first state, the cutout is tightly closed, and in a second state, the cutout is opened by the squeezing force of the gas.

[0009] The present invention is further configured as follows: the one-way valve includes a valve body provided with an air flow channel, a push rod provided on the valve body, and a return elastic member; when the push rod is in a first state, the push rod closes the air flow channel; when the push rod is in a second state, the push rod opens the air flow channel.

[0010] The present invention is further configured such that: the control valve is in sealing cooperation with the second through hole; or, the control valve is a mechanical valve, an electronic valve, or a two-way valve.

[0011] The present invention is further configured as follows: a blocking portion is provided in the tea basket assembly, and the blocking portion is provided above the water conduit; or, the pot body further includes a bottom cover, the container and the bottom cover cooperate to form an installation cavity, and the air pump assembly is provided in the installation cavity.

[0012] The present invention is further configured as follows: the first through hole is provided at the lower part of the cover body, and the position of the first through hole is lower than 1 / 2 of the height of the cover body; or, a notch is provided on the lower edge of the cover body, and the notch cooperates with the bottom wall of the container to form the first through hole.

[0013] The present invention is further configured such that the diameter of the water pipe ranges from 5.5 mm to 10 mm.

[0014] The present invention is further configured to include a controller, which is connected to the heating component and the air pump component respectively. The controller is also used to determine whether the target temperature or target time is reached, and to control the air pump to start or shut down when the target temperature or target time is reached.

[0015] The advantages of the present invention are as follows: when it is necessary to brew tea, firstly, a proper amount of water is poured into the container, a tea strainer component is placed in, and materials to be brewed are added into the tea basket. After the water is heated to a required temperature, the air pump can be started to input air into the kettle body through the ventilation channel. When the air encounters the high-temperature water, it will expand rapidly and be absorbed by the cover body into the water guide pipe; the liquid in the water guide pipe is pushed upward to enter the tea basket to brew the materials in the tea basket; the brewed liquid flows back into the lower part of the kettle body through the mesh holes at the bottom of the tea basket, thereby realizing cyclic brewing; after the brewing is completed, the materials and the tea soup are separated, thereby preventing the materials from being over-soaked and affecting the taste.

[0016] When you don't need to make tea, you can remove the tea strainer and use it as a health pot. When cooking porridge in a conventional health pot, the ingredients tend to accumulate at the bottom of the pot, which can easily lead to a sticky bottom. In this solution, air can be introduced into the container during the initial cooking process. This airflow circulates the liquid inside the pot, stirring the ingredients throughout the pot, preventing them from accumulating at the bottom and effectively preventing sticky bottoms.

[0017] The above technical solution comprises a tea basket on the upper portion of the tea basket assembly, a mesh on the bottom of the tea basket for placing tea leaves in the basket, a water pipe on the middle portion of the tea strainer assembly, the upper end of the water pipe extending into the interior of the tea basket, and preferably, an inverted funnel-shaped cover on the lower portion of the water pipe; the large opening of the funnel entirely covers the interior of the container. In this case, compared to the prior art, the funnel cover needs to be located inside the heating element, and the closer the distance, the better the effect. This technical solution does not require this, and expands the design space of the product. An air pump is connected to the interior of the container through a ventilation channel, and the air pump can send outside air into the container. The air generated in the container is absorbed by the funnel and enters the water pipe. The generated air then pushes the liquid in the water pipe upward into the tea basket assembly to brew the tea in the tea basket assembly. The brewed liquid then flows back into the lower portion of the container through the filter at the bottom of the tea basket, achieving a circular brewing process. Furthermore, a blocking valve is provided in the ventilation channel to prevent liquid from entering the ventilation channel and contaminating the ventilation channel.

[0018] The present invention uses an air pump assembly to deliver external air into the container at a target temperature or a target time, regardless of whether the water is boiling or above 95 degrees. The air generated by the air pump in the container can push the liquid in the water pipe upward and enter the tea basket assembly to brew the material in the tea basket assembly.

[0019] In summary, the above technical solution has the following technical effects:

[0020] 1. The temperature and time are adjustable, which can control the tea brewing temperature and time, and can brew more professional tea without over-brewing the tea.

[0021] 2. When making porridge, the tea strainer component can be removed, and the air pump component can ventilate the container to stir the material at the bottom of the pot to prevent the material from sinking to the bottom and getting stuck.

[0022] 3. The air pump assembly introduces air into the container to increase the carbon dioxide content of the water in the pot, making the water weakly acidic, which is more conducive to brewing tea.

[0023] 4. A teapot with multiple functions, such as the above-mentioned tea brewing function and boiling function, can also be used to boil water separately, with good effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In the description of this embodiment, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "front," and "rear" and the like are used to indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, these terms should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not intended to indicate or imply relative importance.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 8 As shown in

[0036] When ordinary health-care kettles are used to cook porridge, white fungus, etc., the materials are piled up at the bottom of the kettle body. The bottom of the inner liner of the health-care kettle is generally a metal bottom with a heating tube. These materials are easily mushy and form a sticky bottom, which makes the taste worse. The existing technology, such as CN209153061U, adopts a solution of blowing air from the top of the pot lid 7 into the kettle body. This technical solution affects the aesthetics of the pot lid 7, for example, the thickness of the pot lid 7 becomes larger or the structure becomes complicated, and the shape variability is not high. Ordinary consumers directly see the overall outline of the pot lid 7 and the pot body, which makes the overall aesthetics of the health-care kettle insufficient; in addition, the existing technology discloses a method of using a stirring structure in the pot body, such as CN208837599U. In this technical solution, the stirring structure protrudes from the surface of the inner liner, which is not convenient for cleaning. The stirring structure easily powders certain materials, affecting the taste.

[0037] Based on the above technical problems, the present invention proposes a technical solution as follows: a liquid heater, comprising a kettle body, a kettle cover 7 covering the kettle body, and a power base 6 cooperating with the kettle body (a separate power base 6 can also be integrated with the kettle body), wherein the kettle body includes a container 1 for holding liquid, a second through hole 12 being provided at the bottom of the container 1, and an air pump assembly for conveying gas into the container 1, the container 1 being connected to the air pump assembly via the second through hole 12. Preferably, the kettle body further includes a bottom cover 4, the container 1 and the bottom cover 4 cooperate to form an installation cavity, and the air pump assembly is arranged in the installation cavity.

[0038] With the above structure, the inlet for the air pump assembly to transport gas into the container 1 is arranged at the bottom of the inner tank of the container 1. When the health pot is used to cook porridge, boil white fungus, etc., there is no need to insert a conduit as in the prior art, which will not affect the aesthetics of the cooking process. In addition, the conduit is in the container 1, and thick liquids such as porridge will not stick to the conduit, increasing the difficulty of cleaning for the user. The above solution does not have unnecessary cleaning accessories, and at the same time, gas is rushed in when cooking, solving the problems of sticky bottom and increased convection.

[0039] Because conventional electric tea kettles boil water in container 1 to create a large amount of gas within housing 22, which is then forced upward by pressure into the tea basket assembly 5 for spraying, as described in patent application CN201010550290.9, this technical solution lacks the ability to control the brewing temperature and can only use boiling water for brewing tea, failing to accommodate different brewing needs, such as black tea, green tea, ginger tea, scented tea, and coffee, which require different brewing temperatures. Another conventional brewing device, such as that described in patent application CN108814294A, uses a spiral technique to transfer water from container 1 to the tea basket. However, this technique involves a complex screw structure, which occupies a large space within the kettle body, reducing the liquid capacity of container 1 and resulting in a poor user experience.

[0040] Based on the above technical problems, the present invention proposes a technical solution as follows: an automatic tea brewing pot, comprising a pot body, a pot cover 7 covering the pot body, and a power base 6 cooperating with the pot body (the split power base 6 can also be integrated with the pot body), wherein the pot body includes a container 1 for holding liquid and a tea basket assembly 5 provided at the upper inner part of the container 1; a conveying device provided in the container 1, the conveying device including a water pipe 21 located at the upper part and a cover body 22 located at the lower part, the upper end of the water pipe 21 is connected to the inner cavity of the tea basket assembly 5, and the cover body 22 cooperates with the bottom wall of the container 1 to form a steam cavity; an air pump assembly, the air pump assembly delivers the liquid in the container 1 into the tea basket assembly 5 through the conveying device for brewing the brewing substance in the tea basket assembly 5; the steam cavity is connected to the container 1 through the first through hole 221 on the cover body 22, and the steam cavity is connected to the air pump assembly through the second through hole 12 on the bottom wall. Among them, the air pump assembly includes an air pump 31 and a ventilation channel, one end of the ventilation channel is connected to the air pump 31, and the other end is connected to the second through hole 12. The ventilation channel is provided with a vent that can be opened and closed. When the vent is opened, the gas enters the container 1 and the liquid in the container 1 cannot enter the ventilation channel. When the vent is closed, the ventilation channel is closed.

[0041] Among them, the above-mentioned tea basket assembly 5 and the conveying assembly can be assembled together to form an integral tea strainer assembly. At this time, when functions such as brewing tea and coffee are required, the tea strainer assembly is placed in the pot body, and the air pump assembly is started as needed to allow water to enter the tea basket assembly 5 through the water pipe 21 to brew the prepared substance. When functions such as brewing tea and coffee are not required, the entire tea strainer assembly is taken out. At this time, the second through hole 12 is closed, the pot body can be used as a kettle alone, and the tea strainer assembly can be taken out and cleaned separately. Of course, the above-mentioned tea strainer assembly can also be placed inside all the time, or the above-mentioned tea basket assembly 5 and conveying assembly can be stacked and placed in the pot body. Its specific working principle is as follows:

[0042] When it is necessary to make tea, first pour a proper amount of water into the container 1, put in the tea strainer assembly, add the materials to be brewed into the tea basket, and after heating the water to the required temperature, start the air pump 31 to input air into the kettle body through the ventilation channel. When the air encounters the high-temperature water, it will expand rapidly and be absorbed by the cover body 22 into the water guide pipe 21; the liquid in the water guide pipe 21 is pushed up to enter the tea basket to brew the materials in the tea basket; the brewed liquid flows back into the lower part of the kettle body through the mesh at the bottom of the tea basket to achieve cyclic brewing; after brewing is completed, the materials and tea soup are separated to prevent the materials from being over-soaked and affecting the taste.

[0043] When you don't need to make tea, you can remove the tea strainer and use it as a health pot. When cooking porridge in a conventional health pot, the material accumulates at the bottom of the pot, which easily forms a sticky bottom. In this solution, gas can be introduced into the container 1 at the beginning of the cooking process. The introduction of gas will circulate the liquid inside the pot, thereby stirring the material in the entire pot, avoiding the accumulation of material at the bottom of the container 1 and effectively preventing sticky bottom.

[0044] The tea strainer assembly is provided with a water pipe 21 in the middle, and the upper end of the water pipe 21 extends into the interior of the tea basket. Preferably, an inverted funnel-shaped cover 22 is provided at the lower part of the water pipe 21; the large opening of the funnel is entirely covered in the container 1. At this time, compared with the prior art, the funnel cover needs to be arranged on the inner side of the heating element 11, and the closer the distance, the better the effect. The present technical solution has no special requirements for this, and the design space of the product is expanded. The air pump 31 is connected to the container 1 through the ventilation channel. The air pump 31 can send outside air into the container 1. The air generated in the container 1 can be absorbed by the funnel into the water pipe 21, and then the generated air pushes the liquid in the water pipe 21 to move upward into the tea basket assembly 5 to brew the material in the tea basket assembly 5. The brewed liquid flows back into the lower part of the container 1 through the filter at the bottom of the tea basket to achieve circular brewing. At the same time, a blocking valve is provided in the ventilation channel to block liquid from entering the ventilation channel, thereby preventing liquid from reversely entering the ventilation channel and contaminating the ventilation channel.

[0045] The present invention uses an air pump assembly to deliver external air into the container 1 at a target temperature or target time. Regardless of whether the water is boiling or above 95 degrees, the air generated by the air pump 31 in the container 1 can push the liquid in the water pipe 21 upward and enter the tea basket assembly 5 to brew the material in the tea basket assembly 5.

[0046] In summary, the above technical solution has the following technical effects:

[0047] 1. The temperature and time are adjustable, which can control the tea brewing temperature and time, and can brew more professional tea without over-brewing the tea.

[0048] 2. When making porridge, the tea strainer assembly can be removed, and the air pump assembly can ventilate the container 1 to stir the material at the bottom of the pot to prevent the material from sinking to the bottom and becoming sticky.

[0049] 3. The air pump assembly introduces air into the container 1 to increase the carbon dioxide content of the water in the pot body, making the water weakly acidic, which is more conducive to brewing tea.

[0050] 4. A teapot with multiple functions, such as the above-mentioned tea brewing function and boiling function, can also be used to boil water separately, with good effect.

[0051] In order to achieve better water supply effect, the diameter of the water pipe ranges from 5.5mm to 10mm, as shown below

[0052] As shown in Table 1, it is preferably 6.5 mm to 7.5 mm.

[0053]

[0054] Table 1: Experimental data of aqueduct

[0055] Specifically, the air pump assembly includes an air pump 31, a vent tube 32, and a control valve. One end of the vent tube 32 is connected to the second through hole 12, and the other end is connected to the air pump 31. The control valve is located at the second through hole 12 and is used to control the connection between the vent tube 32 and the steam chamber. In this case, the ventilation channel includes the vent tube 32 and the control valve, and the air vent is located on the control valve.

[0056] The control valve has a first state and a second state. In the first state, the vent tube 32 is disconnected from the interior of the container 1; in the second state, the vent tube 32 is connected to the interior of the container 1. The control valve can be a mechanical valve, an electronic valve, a two-way valve, or a one-way valve. Multiple one-way valves can be installed between the air pump 31 and the interior of the container 1.

[0057] In order to prevent water leakage, the present invention is further configured such that the control valve is in sealing cooperation with the second through hole 12 .

[0058] In order to prevent the liquid from splashing during the water filling process, the present invention is further configured to provide a blocking portion 23 in the tea basket assembly 5, and the blocking portion 23 is provided above the water pipe 21.

[0059] Furthermore, in order to enhance the installation stability of the control valve, as Figure 6 As shown, it also includes a mounting bracket 331 for mounting a control valve, the mounting bracket 331 is installed at the bottom of the container 1, the mounting bracket 331 includes a accommodating cavity 3314 for mounting a control valve and an air inlet connected to the accommodating cavity 3314, and the vent pipe 32 is connected to the air inlet.

[0060] Taking the control valve as a one-way valve as an example, when the air pump 31 is turned on, the ventilation gas squeezes the one-way valve to connect the ventilation tube 32 with the steam cavity. When the air pump 31 is closed, the one-way valve closes the passage between the steam cavity and the air pump 31. Specific implementation methods include the following:

[0061] Specifically, a liquid heater, the kettle body includes a container 1, a kettle cover 7, a heating tube provided at the bottom or bottom side of the container 1, and a bottom cover 4, the bottom of the container 1 is also provided with a ventilation channel and an air pump 31, the above-mentioned ventilation channel includes the ventilation pipe 32 and a one-way valve, the air vent is provided on the one-way valve, the one-way valve is a silicone valve 332, the silicone valve 332 is provided with a ventilation part 3321 and a mounting part 3322, the ventilation part 3321 is provided with a cutout, the cutout is the air vent, in the first state, the cutout is tightly closed, and in the second state, the cutout is opened by the squeezing force of the gas.

[0062] like Figure 5 、 7 8, a structural form of a silicone valve 332: an air flow channel 349 for air circulation is provided in the middle of the silicone valve 332, wherein the silicone valve 332 includes a ventilation portion 3321 located at the upper portion and a mounting portion 3322 located below the ventilation portion 3321, the ventilation portion 3321 includes an inclined surface 3321 inclined inwardly and upwardly from the upper end of the mounting portion 3322 and a ventilation slit 3341 on the top surface of the ventilation portion 3321, the ventilation slit 3341 can conduct gas under positive air pressure, and will be closed under negative air pressure, that is, when the air pump 31 is turned on, the air pressure in the ventilation channel is greater than the air pressure in the container 1, generating positive air pressure on the ventilation slit 3341, and the ventilation slit 3341 will be conductive; when the air pump 31 is turned off, the air pressure in the ventilation channel is less than the air pressure in the container 1, and the ventilation slit 3341 will be closed. Under a certain positive pressure, the air flow can flow through these holes or gaps, and then enter the inside of the kettle to make the liquid roll, making the water temperature uniform.

[0063] like Figure 3 As shown, another structural form of a silicone valve 332: an air flow channel 349 for air circulation is provided in the middle of the silicone valve 332, wherein the silicone valve 332 includes a ventilation portion 3321 located at the lower portion and a mounting portion 3322 located above the ventilation portion 3321, the ventilation portion 3321 includes an inclined surface 3321 inclined inward and upward from the lower end of the mounting portion 3322 and a ventilation slit 3341 on the top surface of the ventilation portion 3321, the ventilation slit 3341 can conduct gas under positive air pressure, and will be closed under negative air pressure, that is, when the air pump 31 is turned on, the air pressure in the ventilation channel is greater than the air pressure in the container 1, generating positive air pressure on the ventilation slit 3341, and the ventilation slit 3341 will be conductive; when the air pump 31 is turned off, the air pressure in the ventilation channel is lower than the air pressure in the container 1, and the ventilation slit 3341 will be closed. Under a certain positive pressure, the air flow can flow through these holes or gaps, and then enter the inside of the kettle to make the liquid roll, making the water temperature uniform.

[0064] The edges of the inclined surface 3321 and the air vent 3341 can form an inclined "7" shape or an inclined "1" shape. At this time, the mounting portion 3322 is in the shape of a hollow cylinder.

[0065] Specifically, if Figure 3 As shown, in order to achieve a better sealing effect at the second through hole 12 while not affecting the effect of the silicone valve 332, a sealing silicone 334 is also included. The sealing silicone 334 is embedded in the second through hole 12 to form a seal for the second through hole 12, and a ventilation slit 3341 is opened at the top of the sealing silicone 334. This strengthens the stability of the ventilation channel and provides a double guarantee to prevent the backflow of liquid in the container 1. At this time, the lower end of the sealing silicone 334 and the upper end of the silicone valve 332 are docked, sleeved, or integrally formed, and the sealing silicone 334 and silicone valve 332 are installed in the accommodating cavity 3314 and fixed to the bottom of the container 1 via the mounting bracket 331.

[0066] Specifically, if Figure 4 、 5 As shown, since the sealing silicone 334 and the silicone valve 332 are both soft when they are separated, there is a problem of unstable docking, which is prone to deviation, resulting in a weakened sealing effect of the second through hole 12 or the possibility of air leakage. Therefore, in order to make the sealing effect of the second through hole 12 better without affecting the effect of the silicone valve 332, a fixing seat 333 and a sealing silicone 334 are also included. The sealing silicone 334 and the silicone valve 332 are respectively arranged on both sides of the fixing seat 333. The sealing silicone 334, the silicone valve 332, and the fixing seat 333 are installed in the accommodating cavity 3314. Preferably, the fixing seat 333 is H-shaped and has an opening 3331 for ventilation in the middle. The sealing silicone 334 is embedded in the second through hole 12 to form a sealing effect on the second through hole 12, and a ventilation seam 3341 is opened on the top of the sealing silicone 334. Of course, the sealing silicone 334 and the vent slit 3341 on the silicone valve 332 can be staggered to enhance the stability of the vent channel and provide a double safeguard to prevent the backflow of liquid in the container 1.

[0067] The mounting portion 3322 of the silicone valve 332 is an annular flange. The upper and lower surfaces of the flange press against the lower end of the fixing seat 333 and the inner surface of the mounting bracket 331, respectively. Under the action of pressure, this flange forms a seal between the fixing seat 333 and the mounting bracket 331. The fixing seat 333 is an annular plastic component. Its upper portion presses against the flange of the sealing silicone 334, and its lower portion presses against the flange of the one-way valve silicone. This creates a sealing relationship between the fixing seat 333, the sealing silicone 334, and the one-way valve.

[0068] The mounting bracket 331 is connected to the aluminum plate at the bottom of the container 1 by screws. The mounting bracket 331 presses the one-way valve, the fixing seat 333 and the sealing silicone 334 in sequence. The one-way valve, the fixing seat 333 and the sealing silicone 334 are sealed with each other by the pressure of the mounting bracket 331.
