Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a kettle body with a steam reflux structure. Background Art

[0002] Cold brew kettles are used at home or in the workplace. A cold brew kettle is a tool for making cold brew coffee. It is usually made of stainless steel, glass or plastic. By using a cold brew kettle, high-quality cold brew coffee can be easily made by oneself. There are already quite a few devices related to coffee extraction that have been publicly disclosed. For example, Chinese Patent Publication No. CN109288395A discloses a coffee extraction device, including a lower kettle. An opening is provided above the lower kettle. A first retaining ring is provided in the opening of the lower kettle. A powder tank is placed on the first retaining ring. By providing the powder tank, it is convenient to place coffee powder in the powder tank. A second retaining ring is provided above the inner part of the powder tank. A filter plate is placed above the second retaining ring. An upper kettle is provided above the filter plate. A cooling column is fixedly provided inside the upper kettle. A through hole is provided inside the cooling column. The upper part of the cooling column is connected to a baffle through a connecting rod. The baffle is arranged in a pagoda shape. When working, after the liquid mixture in the lower kettle boils, the vaporized coffee rises upward, reaches the baffle through the cooling column, and liquefies into coffee when the vaporized coffee contacts the baffle. The utility model has reasonable design, simple structure and high extraction efficiency.

[0003] However, the structural defect of this cold brew kettle is that during operation, some steam will rise to condense on the lower surface of the cover plate. When the cover plate is opened, there will be a phenomenon that the condensed steam flows downward to the edge of the upper kettle or flows out of the upper kettle, which easily causes dirt and affects the product experience. Based on this, it is necessary to have a kettle body with a steam reflux structure to solve the above problems. Summary of the Utility Model

[0004] The utility model overcomes the shortcomings in the prior art and provides a kettle body with a steam reflux structure, which helps the steam to reflux into the kettle body, avoiding the outflow of steam and resulting in dirt, thus affecting the use.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A kettle body with a steam reflux structure includes a kettle body. The kettle body has a cavity. An opening is provided above the kettle body. A cover body is hinged at the opening. A flow-blocking member is provided on the bottom surface of the cover body. The flow-blocking member extends downward and is arranged near the hinge of the cover body and the kettle body. When the cover body is in the closed state, the flow-blocking member is located on one side of the inner wall of the opening. When the cover body is opened, the flow-blocking member rotates with the cover body. The steam on the bottom surface of the cover body will flow downward to the inside of the flow-blocking member. And as the opening angle of the cover body gradually increases, the angle at which the flow-blocking member inclines towards the center of the kettle body becomes larger.

[0007] Furthermore, the pot body includes a bottle body and a handle. The cover body is hinged to the handle, and the handle is detachably sleeved above the bottle body. The handle is provided with a liquid inlet, and the liquid inlet communicates with the cavity. The handle is provided with a funnel-shaped inclined surface that smoothly inclines from the periphery towards the liquid inlet direction.

[0008] Furthermore, the handle is provided with a liquid outlet, and the liquid outlet communicates with the cavity. The liquid outlet includes a concave arc surface, and the concave arc surface forms a downward-probing shape relative to the funnel-shaped inclined surface. It also includes several railings. One end of the railing is connected to the concave arc surface, and the other end of the railing is connected to the funnel-shaped inclined surface. Side walls are formed on both sides of the concave arc surface. From a top-down view, along the outward flow direction of the liquid, the side walls on both sides are in a gradually converging and gathering shape.

[0009] Furthermore, the handle is further provided with a handgrip, and the handgrip is located on the side opposite to the liquid outlet. And from a top-down view, the symmetry line of the liquid outlet coincides with the symmetry line of the handgrip.

[0010] Furthermore, the liquid outlet is located on the side close to the handgrip.

[0011] Furthermore, the handle is provided with a mounting member. The cover body includes a pressing plate, and the pressing plate is provided with an opening. The mounting member is provided with a shaft body, and the opening is rotatably connected to the shaft body. The mounting member is provided with a positioning catch point. The inner wall of the pressing plate is provided with a positioning slot that matches the positioning catch point. When the cover body is opened to the maximum angle, the positioning catch point is embedded in the positioning slot. When the cover body is closed, the connection line between the shaft body and the positioning slot is perpendicular to the connection line between the shaft body and the positioning catch point.

[0012] Furthermore, the pressing plate is formed in a cover plate shape by surrounding. When the cover body is opened to the maximum angle, the pressing plate wraps around the outside of the mounting member, and the inner wall of the pressing plate abuts against the outer wall of the mounting member.

[0013] Furthermore, the pressing plate extends outwards and protrudes relative to the mounting member.

[0014] Furthermore, a lip is formed on the bottom surface of the cover body. The left and right sides of the flow-blocking member are connected to the lip to form a closed loop as a whole. The inner wall at the top end of the handle is provided with a side-edge step position that matches the shape of the lip.

[0015] Furthermore, the handle is threadedly connected to the bottle body. A sealing ring is provided at the connection between the handle and the bottle body.

[0016] Furthermore, the lower end of the handgrip extends downwards to have a recycling position that approaches the pot body.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] The utility model overcomes the phenomenon of steam outflow during the use of a traditional kettle by providing a flow-blocking member on the bottom surface of the lid. When the lid is opened, the steam on the bottom surface of the lid will flow downward to the inside of the flow-blocking member and finally flow back into the kettle, avoiding the outflow and preventing the kettle and its surrounding area from getting dirty, which may affect the use.

[0032] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0033] As Figures 1 to 8 shown, the present utility model discloses a kettle body with a steam reflux structure. This kettle body is mainly used as a cold brew kettle. One of its functions is that when the lid 2 is opened, the steam condensed on the bottom surface of the lid 2 will flow back down into the interior of the kettle body, and there will be no external leakage resulting in dirt. The specific implementation is as follows: It includes a kettle body 1. The kettle body 1 has a cavity. An opening is provided above the kettle body 1. A lid 2 is hinged at the opening. The lid 2 is designed to be openable and closable, serving to seal the cavity of the kettle body 1.

[0034] The kettle body 1 includes a bottle body 101 and a handle 102. The handle 102 is detachably sleeved above the bottle body 101, making it easy to assemble and disassemble the handle 102 and the bottle body 101, facilitating daily disassembly, cleaning, and then reassembly for use. In this embodiment, the handle 102 is threadedly connected to the bottle body 101. Combining Figure 3 and Figure 4 viewing, an external thread is provided on the bottle body 101, and an internal thread is correspondingly provided on the inner wall of the handle 102. The two are fixed by the external thread and the internal thread. This not only facilitates assembly and disassembly but also has good stability and is not likely to fall off or separate on its own. In addition, a sealing ring 3 is provided at the connection between the handle 102 and the bottle body 101, which can enhance the sealing performance between the two.

[0035] The opening above the kettle body 1 mentioned above refers to the opening at the top of the handle 102. The lid 2 is hinged on the handle 102, thereby opening or closing the opening. The cavity of the kettle body 1 mentioned above refers to the internal cavity of the bottle body 101. An inlet 1021 is provided on the handle 102. The inlet 1021 is communicated with the cavity. After the lid 2 is opened, liquid is poured into the cavity from the inlet 1021. In addition, combining Figure 3 and Figure 5It can be seen that the handle 102 is provided with a funnel-shaped inclined surface 1022 that smoothly inclines from the periphery towards the liquid inlet 1021. The funnel-shaped inclined surface 1022 is more conducive to the smooth pouring of liquid into the liquid inlet 1021. During the pouring process, when the liquid is poured on the funnel-shaped inclined surface 1022, it will also flow along the funnel-shaped inclined surface 1022 and finally flow into the liquid inlet 1021. The advantage of the inclined setting of the funnel-shaped inclined surface 1022 is that when there is liquid sprayed on the surface of the funnel-shaped inclined surface 1022, it will also slide into the liquid inlet 1021 by itself under the action of gravity, which helps to keep the funnel-shaped inclined surface 1022 dry. In addition, a filter screen cylinder can be installed in the liquid inlet 1021 to filter the residues in the poured liquid. The upper peripheral edge of the filter screen cylinder is lapped on the periphery of the liquid inlet 1021, and the filter screen cylinder can be put in or taken out according to actual needs. Therefore, another advantage of the funnel-shaped inclined surface 1022 is that it helps to enhance the limiting effect on the filter screen cylinder because the contact surfaces of the upper peripheral edges of the filter screen cylinder are all inclined surfaces at this time, so it is not easy to shift.

[0036] The handle 102 is provided with a liquid outlet 1023, and the liquid outlet 1023 is communicated with the cavity. When in use, the kettle body 1 is tilted so that the liquid in the cavity is poured out from the liquid outlet 1023. Among them, the liquid outlet 1023 includes a concave arc surface 10231, and the concave arc surface 10231 forms a downward-probing shape relative to the funnel-shaped inclined surface 1022; it also includes a number of railings 10232, and the number of railings 10232 forms a filter screen surface. One end of the railing 10232 is connected to the concave arc surface 10231, and the other end of the railing 10232 is connected to the funnel-shaped inclined surface 1022; therefore, when pouring out the liquid, the liquid is discharged from the gaps between adjacent railings 10232. On the one hand, the railings 10232 play a role of filtering and isolation. When the liquid in the cavity has residues, it will be filtered and stay in the cavity; on the other hand, even if the liquid in the cavity has no residues, the railings 10232 play a role of blocking and buffering the flow, preventing the liquid from splashing out of the liquid outlet 1023 all at once; side walls 10233 are formed on both sides of the concave arc surface 10231. As Figure 6 shown, when viewed from the top-down direction, along the outward flow direction of the liquid, the side walls 10233 on both sides are in a gradually converging and gathering shape. This converging design enables the liquid to gradually converge during discharge, achieving the effects of not being easily diffused and guiding the flow. From Figure 5 it can be seen that the concave arc surface 10231 is in a downward-probing shape, so that the concave arc surface 10231 and the side walls 10233 on both sides enclose a liquid storage area. When the liquid is poured out by tilting, the liquid first discharges from the gaps between adjacent railings 10232 into the liquid storage area, and as the liquid continues to be poured in, it then flows out along the discharge to the outside, achieving the effect of buffering the flow and also solving the problem of excessive water discharge and splashing when the traditional kettle body starts to be tilted.

[0037] The handle 102 is further provided with a grip 1024. After the handle 102 is fixed to the bottle body 101, the grip 1024 is held for operation. The grip 1024 is located on the side opposite to the liquid outlet 1023. And from the top view direction, the symmetry line of the liquid outlet 1023 coincides with the symmetry line of the grip 1024. In fact, the grip 1024 and the liquid outlet 1023 are located on the left and right sides of the symmetry line of the entire handle 102. Since when pouring, the grip 1024 is held for pouring, at this time the grip 1024 is at a high position and the liquid outlet 1023 is at a low position, which helps to pour the liquid in the kettle body 1 smoothly. In addition, the liquid outlet 1023 is located on the side close to the grip 1024 and is at a high position when pouring, which also prevents the liquid in the cavity from overflowing from the liquid outlet 1023 when pouring.

[0038] The lower end of the grip 1024 extends downward to have a recovery position 10241 close to the kettle body 1, so that it is not easy to loosen after the grip 1024 is held.

[0039] The handle 102 is provided with a mounting member 1025. The cover body 2 includes a pressing plate 202. The pressing plate 202 extends outward and protrudes relative to the mounting member 1025. Therefore, when the cover body 2 is in the closed state, pressing the pressing plate 202 downward with a finger can drive the cover body 2 to flip and open, which is very convenient. When the cover body 2 is closed, the top opening of the handle 102 is completely sealed. Therefore, when pouring liquid or pouring out liquid, the cover body 2 needs to be opened. The cover body 2 is completely sealed to achieve a good sealing and dust-proof effect. The pressing plate 202 is provided with an opening 203, and the mounting member 1025 is provided with a shaft body 10251. The opening 203 is rotatably connected to the shaft body 10251. Through this structure, the pressing plate 202 is rotatably assembled on the mounting member 1025. And the mounting member 1025 is provided with a positioning clamping point 10252, and the inner wall of the pressing plate 202 is provided with a positioning clamping position 204 that matches the positioning clamping point 10252. When the cover body 2 is opened to the maximum angle as shown in Figure 3 When shown, the positioning clamping point 10252 is embedded into the positioning clamping position 204 to achieve the positioning function, without the need to support it with an extra hand, which is convenient for use. When the cover body 2 needs to be re-closed, push the cover body 2 back with your hand to make the positioning clamping point 10252 disengage from the positioning clamping position 204.

[0040] A lip 205 is formed on the bottom surface of the cover body 2. The left and right sides of the flow blocking member 201 are connected to the lip 205 to form a closed loop as a whole. The inner wall of the top end of the handle 102 is provided with a side line step position 1026 that matches the shape of the lip 205. When the cover body 2 is closed, the lip 205 is embedded and lapped on the side line step position 1026. This design helps to enhance the stability of the cover body 2 and prevent it from swinging left and right.

[0041] A flow-blocking member 201 is provided on the bottom surface of the lid body 2. The flow-blocking member 201 extends downward and is arranged near the hinge joint of the lid body 2 and the kettle body 1. From the above description and the attached drawings, it can be seen that the flow-blocking member 201 is on the side close to the pressing plate 202. When the lid body 2 is in the closed state, the flow-blocking member 201 is located on one side of the inner wall of the opening. When the lid body 2 is opened, the flow-blocking member 201 rotates with the lid body 2. The steam on the bottom surface of the lid body 2 will flow downward to the inner side of the flow-blocking member 201 and flow back to the cavity along the flow-blocking member 201, achieving the effect of steam reflux and avoiding overflow. As the opening angle of the lid body 2 gradually increases, the larger the angle at which the flow-blocking member 201 inclines towards the center of the kettle body 1, that is, as the lid body 2 is opened, it is more conducive to the steam flowing downwards to flow towards the center inside the kettle body 1 without overflowing. When the lid body 2 is closed, the flow-blocking member 201 is also located on the inner wall of the opening, and the steam can ultimately only flow downward and back to the cavity, with a clever structure.

[0042] Based on this, the design of the opening angle of the lid body 2 of this kettle body also has a specific intention. For example, when designing the position of the positioning clamping point 10252, the following requirements are met: when the lid body 2 is closed, the connection line between the shaft body 10251 and the positioning clamping position 204 is perpendicular to the connection line between the shaft body 10251 and the positioning clamping point 10252. That is, when the lid body 2 is closed, it is in a horizontal state. When the lid body 2 is opened to the maximum state, it rotates 90 degrees. At this time, the positioning clamping point 10252 will be embedded in the positioning clamping position 204 for limitation and cannot be opened further. Figure 3 From this, it can be ensured that the lower edge of the flow-blocking member 201 always remains above the opening of the handle 102 when the lid body 2 is opened, which helps to ensure that the steam sliding down along the flow-blocking member 201 can only flow back to the opening of the handle 102 and can also prevent steam from flowing out. In addition, in order to enhance the limiting effect on the lid body 2 at this time, the pressing plate 202 is formed in a surrounding cover shape. When the lid body 2 is opened to the maximum angle, the pressing plate 202 is wrapped outside the mounting member 1025, and at this time, the inner wall of the pressing plate 202 abuts against the outer wall of the mounting member 1025, also achieving the effect of further restricting the rotation of the lid body 2.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
