[0034] Figures 1 to 10 It is a schematic diagram of some embodiments of a hand-poured kettle of the present invention.

[0035] Reference Figures 1 to 10 , and mainly refer to Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig.10A hand-infusing kettle according to some embodiments of the present invention is sometimes referred to as a "hand-infusing kettle" for ease of description. A hand-infusing kettle according to some embodiments of the present invention comprises a kettle body 100, a liquid output pipe 200, a handle 300 and a sealing cover 400. In this embodiment, the kettle body 100 is a rotating body with a small upper part and a large lower part. A receiving cavity 110 is provided inside the kettle body 100. The receiving cavity 110 can be used to load materials such as water, coffee or tea. An opening 120 communicating with the receiving cavity 110 is provided at the upper part of the kettle body 100. The sealing cover 400 is detachably mounted on the opening 120 at the upper part of the kettle body 100. When the sealing cover 400 is installed on the opening 120 on the upper part of the kettle body 100, the sealing cover 400 can seal the opening 120. When the user removes the sealing cover 400 from the opening 120 on the upper part of the kettle body 100, the sealing cover 400 opens the opening 120. At this time, external water or coffee powder or tea leaves can enter the accommodating chamber 110 through the above opening 120. After the materials are added, the user can install the sealing cover 400 on the opening 120 on the upper part of the kettle body 100 again and block the opening 120. The liquid output pipe 200 is arranged on the outer surface of one side of the kettle body 100, the lower end of the liquid output pipe 200 is connected to the accommodating chamber 110, and the upper end of the liquid output pipe 200 has a liquid output nozzle 210. The liquid loaded in the receiving chamber 110 can flow into the liquid output tube 200 from the position where the lower end of the liquid output tube 200 is connected to the receiving chamber 110, and then the liquid flows out from the liquid output nozzle 210 at the upper part of the liquid output tube 200. In this embodiment, the liquid output tube 200 is roughly S-shaped. The upper end of the liquid output tube 200 is extended upward so that the upper end level of the liquid output tube 200 is basically consistent with the upper part level of the pot body 100, or the upper end level of the liquid output tube 200 is slightly lower than the upper part level of the pot body 100. The handle part 300 is arranged on the side of the pot body 100 away from the liquid output tube 200. In this embodiment, when the pot body 100 is tilted on a support surface such as a desktop or the ground, the center of gravity of the pot body 100 is located at the handle part 300, and the pot body 100 is subjected to gravity and the handle part 300 is in a state of swinging downward and the liquid output tube 200 is in a state of swinging upward.

[0036] The hand-infused kettle of this embodiment is provided with the liquid delivery pipe 200 and the handle 300 on opposite sides of the shell body 100, and the shell body 100 is arranged so that when the shell body 100 is tipped onto a supporting surface, the center of gravity of the kettle body 100 is located at the handle 300. Therefore, when the hand-infused kettle of this embodiment is accidentally tipped onto a supporting surface such as a desktop or the ground, Figure 7 and Figure 8As shown, under the action of gravity, the handle portion 300 of the kettle body 100 is in a state of swinging downward and the liquid output pipe 200 is in a state of swinging upward. At this time, the liquid output nozzle 210 of the liquid output pipe 200 is in a high position, that is, the horizontal height of the liquid output nozzle 210 is substantially higher than the horizontal height of the kettle body 100. Therefore, most of the liquid in the accommodating cavity 110 cannot flow out from the liquid output nozzle 210, and the opening 120 at the upper part of the kettle body 100 is also blocked by the sealing cover 400. Therefore, the liquid in the accommodating cavity 110 cannot flow out from the opening 120 at the upper part of the kettle body 100. Therefore, the liquid flowing out when the hand-injected kettle accidentally falls on the supporting surface is greatly reduced, which not only avoids the waste caused by the large amount of liquid flowing out of the hand-injected kettle, but also reduces the probability of liquid seeping into other power supply equipment and causing short circuit or leakage, thereby improving the safety of the hand-injected kettle.

[0037] It should be noted that, in the above embodiment, the kettle body 100 is a rotating body with a shape that is small on the top and large on the bottom. In other embodiments of the present invention, the kettle body 100 can also be set to other shapes, such as the kettle body 100 is cylindrical, or the kettle body 100 is a rectangular parallelepiped, etc., which can be determined according to actual needs, and the kettle body 100 is not limited to a rotating body with a shape that is small on the top and large on the bottom.

[0038] Reference Figure 4 , Figure 5 , Fig. 9 and Fig.10 In order to make the sealing cover 400 better seal the opening 120 at the top of the pot body 100, in some embodiments of the present invention, the upper part of the accommodating cavity 110 has a sealing boss portion 111, and the sealing boss portion 111 is arranged along the inner wall circumferentially of the accommodating cavity 110. When the sealing cover 400 is detachably mounted on the opening 120, the sealing boss portion 111 is in sealing contact with the lower end surface and / or the outer side wall of the sealing cover 400. Specifically, the upper part of the pot body 100 is sealed with an annular hollow part 130 extending into the interior of the accommodating cavity 110, the opening 120 is arranged at the upper part of the annular hollow part 130, and the sealing boss portion 111 is arranged at the middle and lower part of the inner wall of the annular hollow part 130; when the sealing cover 400 is detachably mounted on the opening 120, the sealing cover 400 is embedded in the interior of the annular hollow part 130, and the sealing boss portion 111 is in sealing contact with the lower end surface and / or the outer side wall of the sealing cover 400. By adopting the above structure, the production and processing of the kettle body 100 is facilitated, and the sealing cover 400 can better seal the above opening 120 to meet the needs of users.

[0039] In order to prevent the sealing cover 400 from accidentally falling out of the opening 120, in some embodiments of the present invention, one or more locking structures are arranged between the sealing cover 400 and the annular hollow part 130, and the locking structures include a clamping groove 510 and a clamping block 520 that can cooperate and engage with each other. When the clamping groove 510 is arranged on the outer wall of the sealing cover 400, the clamping block 520 is arranged on the inner wall of the annular hollow part 130; or when the clamping groove 510 is arranged on the inner wall of the annular hollow part 130, the clamping block 520 is arranged on the outer wall of the sealing cover 400. By adopting the above structure, when the sealing cover 400 is installed on the opening 120, the sealing cover 400 and the annular hollow part 130 can be locked together through the cooperation and engagement of the clamping block 520 and the clamping groove 510, effectively preventing the sealing cover 400 from accidentally falling out of the opening 120, and ensuring the sealing performance of the sealing cover 400 in sealing the opening 120.

[0040] It should be noted that, in the above embodiment, the locking structure is a clamping structure in which the clamping groove 510 and the clamping block 520 cooperate with each other, while in other embodiments of the present invention, the locking structure can also adopt other structures, such as the locking structure includes an internal thread and an external thread that can cooperate with each other in threaded connection, the internal thread is opened on the inner wall of the annular hollow part 130, and the external thread is opened on the outer wall of the sealing cover 400. When the sealing cover 400 is installed in the opening 120 at the upper part of the pot body 100, the sealing cover 400 is screwed into the inside of the annular hollow part 130, and is threadedly connected to each other through the external thread and the internal thread, thereby locking the sealing cover 400 and the annular hollow part 130 together, effectively preventing the sealing cover 400 from accidentally falling off from the opening 120, and ensuring the sealing performance of the sealing cover 400.

[0041] Reference Figure 5 , Figure 6 , Fig. 9 and Fig.10 In some embodiments of the present embodiment, the snap-in groove 510 is opened on the inner wall of the annular hollow part 130, and the snap-in block 520 is arranged on the outer wall of the sealing cover 400. The snap-in groove 510 includes a vertical entry and exit groove 511 and a horizontal snap-in groove 512. The lower end of the vertical entry and exit groove 511 is connected with one end of the horizontal snap-in groove 512. Specifically, the vertical entry and exit groove 511 and the horizontal snap-in groove 512 are connected and make the snap-in groove 510 roughly "L"-shaped. When the sealing cover 400 is detachably installed on the opening 120, the snap-fit ​​block 520 can slide from top to bottom to the lower end of the vertical entry and exit groove 511, and then the user twists the sealing cover 400 to rotate horizontally relative to the kettle body 100. At this time, the snap-fit ​​block 520 can move relative to the vertical entry and exit groove 511 and embed into the transverse snap-fit ​​groove 512. At this time, the snap-fit ​​block 520 is snapped with the transverse snap-fit ​​groove 512, thereby limiting the sealing cover 400 from moving upward relative to the kettle body 100 and detaching from the opening 120.

[0042] In certain embodiments of the present invention, a sealing cushion 410 capable of being squeezed and deformed is provided at the lower end of the sealing cover 400, and the upper surface of the snap-in block 520 is an inclined surface, and the horizontal height of one end of the inclined surface close to the transverse snap-in groove 512 is lower than the horizontal height of the other end of the inclined surface away from the transverse snap-in groove 512. By adopting the above structure, the snap-in block 520 is in the shape of a wedge. When the sealing cover 400 is detachably installed on the opening 120, the clamping block 520 first slides from the top to the bottom to the lower end of the vertical inlet and outlet groove 511, and then the user twists the sealing cover 400 to rotate horizontally relative to the kettle body 100. At this time, the end with a lower horizontal height of the upper inclined surface of the clamping block 520 first abuts against the upper surface of the horizontal clamping groove 512, and then the user continues to twist the sealing cover 400 to rotate horizontally relative to the kettle body 100. At this time, the upper surface of the horizontal clamping groove 512 slides along the upper inclined surface of the clamping block 520 from the end with a lower horizontal height to the end with a higher horizontal height. In this process, the horizontal clamping groove 512 cooperates with the clamping block 520 and pushes the sealing cover 400 to move downward, so that the sealing boss portion 111 can better squeeze the sealing cushion 410 that is tightly attached to the lower end of the sealing cover 400, thereby making the sealing effect of the sealing cover 400 sealing the opening 120 better.

[0043] Furthermore, in order to ensure that the sealing cover 400 can be subjected to force balance when installed on the opening 120, in some embodiments of the present invention, the number of locking structures is two groups, and the two groups of locking structures are arranged one by one on the inner walls of the annular hollow part 130 on both sides opposite each other, that is, the inner walls of the annular hollow part 130 on both sides opposite each other are respectively provided with a clamping groove 510, and the outer walls of the sealing cover 400 on both sides opposite each other are respectively provided with a clamping block 520; or the inner walls of the annular hollow part 130 on both sides opposite each other are respectively provided with a clamping block 520, and the outer walls of the sealing cover 400 on both sides opposite each other are respectively provided with a clamping groove 510. When the sealing cover 400 is installed on the opening 120, the two clamping blocks 520 and the two clamping grooves 510 are matched and clamped one by one. By adopting the above structure, when the sealing cover 400 is installed on the opening 120, the two sets of locking structures can lock the sealing cover 400 on the opening 120 from both sides of the sealing cover 400, thereby making the force on the sealing cover 400 more balanced.

[0044] Reference Figure 1 , Figure 2 , Figure 3In order to make the hand-brewed kettle have a heating function, in some embodiments of the present invention, a mounting cavity 140 is provided at the lower part of the kettle body 100, and the mounting cavity 140 and the accommodating cavity 110 are isolated from each other. A heating component 141 is provided inside the mounting cavity 140 and is in contact with the outer bottom wall of the accommodating cavity 110. In this embodiment, the inner bottom wall and the outer peripheral wall of the accommodating cavity 110 are both made of metal. Therefore, when the heating component 141 abutting against the outer bottom wall of the accommodating cavity 110 is powered on and heated, the heating component 141 can heat the bottom of the accommodating cavity 110, and then heat the material loaded in the accommodating cavity 110, so that the hand-brewed kettle of this embodiment has a heating function. In this embodiment, the heating component 141 is a resistance heating wire or a resistance heating disk that can generate heat when powered on.

[0045] In order to monitor whether the liquid in the accommodating chamber 110 is heated to the set temperature, in some embodiments of the present invention, a steam pipe 150 is provided inside the accommodating chamber 110. The steam pipe 150 is a hollow pipe. The steam pipe 150 includes an upper steam pipe 151 and a lower steam pipe 152 that are connected to each other. The upper steam pipe 151 is provided with a steam inlet 1510. The lower steam pipe 152 is provided with a steam outlet that is connected to the installation chamber 140. The lower steam pipe 152 extends to the installation chamber 140. A temperature sensor for the lower steam pipe 152 to cooperate with the detection is provided inside the installation chamber 140. A control circuit board is provided in the installation chamber 140. The control circuit board is electrically connected to the temperature sensor and the heating assembly 141. The steam inlet 1510 and the steam outlet are provided on both sides of the handle 300 in a one-to-one correspondence. In some embodiments of the present invention, the steam pipe 150 includes a transverse connecting section 153 , the lower end of the upper steam pipe 151 is connected to one end of the transverse connecting section 153 , and the upper end of the lower steam pipe 152 is connected to the other end of the transverse connecting section 153 .

[0046] By adopting the above structure, the control circuit board controls the heating component 141 to heat the liquid in the accommodating chamber 110. When the liquid is heated to a certain temperature and generates steam, the steam can enter the upper steam pipe 151 through the steam inlet 1510 at the upper part of the upper steam pipe 151, and then the steam flows along the upper steam pipe 151 to the lower steam pipe 152. The steam finally flows from the steam outlet to the temperature sensor. The temperature sensor detects the steam and can detect that the liquid has been heated to the set temperature. The temperature sensor sends an electrical signal to the control circuit board, and the control circuit board controls the heating component 141 to cut off the power and stop heating. The heat-resistant and simple structure helps to reduce the production cost of the hand-brewed kettle; and the steam inlet 1510 and the steam outlet are arranged one by one on both sides of the handle portion 300, so that when the hand-brewed kettle accidentally tips over onto a supporting surface such as a desktop or the ground, no matter which direction the kettle body 100 is tilted, one of the steam inlet 1510 and the steam outlet is in a high position and the other is in a low position, so that the liquid in the accommodating cavity 110 cannot flow into the installation cavity 140 from the steam pipe 150, which helps to prevent the liquid in the accommodating cavity 110 from leaking into the installation cavity 140 through the steam pipe 150 and being discharged from the outside of the kettle body 100.

[0047] Reference Figures 1 to 3 In order to facilitate the user to install and remove the sealing cover 400, in some embodiments of the present invention, a gripping portion 420 is provided on the upper portion of the sealing cover 400. Therefore, the user can hold the gripping portion 420 to drive the sealing cover 400 to move up and down or rotate horizontally relative to the kettle body 100, thereby facilitating the user to install and remove the sealing cover 400.

[0048] In order to facilitate power supply to the electronic components placed in the installation cavity 140, a hand brewing kettle in some embodiments of the present invention further includes a power supply base 600, a lower coupler 610 is provided in the middle of the upper surface of the power supply base 600, and an upper coupler capable of coupling with the lower coupler 610 is provided on the lower bottom wall of the kettle body 100. When the kettle body 100 of this embodiment is detachably installed on the power supply base 600, the upper coupler at the bottom of the kettle body 100 is coupled and conductively connected with the lower coupler 610, thereby facilitating the power supply base 600 to supply power to the electronic components such as the control circuit board, the temperature sensor and the heating assembly 141 placed in the installation cavity 140. Since the upper coupler and the lower coupler 610 belong to the conventional technology in the art, they will not be described in detail here.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
