Description

Technical Field

[0001] The utility model belongs to the technical field of container structures, and specifically relates to a portable kettle with anti-blocking air vents. Background Art

[0002] The kettles commonly seen on the market now usually have the handle on one side. Besides preventing scalding, the reason is also to save space. Although it saves space, it is not labor-saving. Moreover, the kettles with the handle on one side usually cannot use an open fire. Therefore, for going outdoors or transferring positions up and down the stairs at home, the beam-type kettle is more convenient and labor-saving.

[0003] The design of the position of the air vent of the beam-type kettle is more particular. First of all, the position of the air vent cannot be set in the opposite direction of the spout, because when pouring water, the position of the air vent will face the arm, and the steam spouted out is easy to scald the arm. Secondly, the air vent cannot be set on the kettle lid. Due to the beam design, it is easy to scald the fingers when pouring water. In addition, considering aesthetics, the air vent will not be set on both sides of the kettle body either. So the air vent can only be set on the same side as the spout, usually at the upper end of the kettle body. However, in this design, when the kettle is filled with more water and the kettle body is in an inclined state when pouring water, the water in the kettle body will cover the air vent, resulting in unsmooth water discharge. If it is just-boiled water, when pouring water, the air pressure in the kettle body will increase, and water will also be spouted out at the air vent, which is easy to cause injury to others. Content of the Utility Model

[0004] The purpose of the utility model is to provide a portable kettle with anti-blocking air vents to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A portable kettle with anti-blocking air vents, including a kettle body. An air vent is provided at a position corresponding to the spout on the kettle body. An exhaust passage communicating with the air vent is provided in the inner cavity of the kettle body. The exhaust passage is provided with an opening, and the opening is always above the liquid level.

[0007] In a further technical solution, the air vent is provided at the upper part of the kettle body. A shielding member is fixedly provided along the upper edge of the inner cavity of the kettle body. The shielding member covers the air vent and encloses an exhaust passage with the inner wall of the kettle body.

[0008] In a further technical solution, the bottom surface of the inner wall of the shielding member is designed to be inclined downward from the air vent to the opening position.

[0009] In a further technical solution, the air vent is designed to be inclined downward.

[0010] In a further technical solution, a storage structure is provided between the spout and the kettle body.

[0011] Further technical solution: The storage structure includes a connection port provided on the side wall of the kettle body. A spout is inserted through the connection port, and a waterproof rubber sleeve is provided between the spout and the connection port.

[0012] Further technical solution: The spout includes a water passage part. One end of the water passage part is provided with a first limiting part, and the first limiting part can abut against the inner cavity of the kettle body.

[0013] Further technical solution: A storage groove is provided at the connection port. The other end of the water passage part is provided with a second limiting part, and the second limiting part can enter the storage groove.

[0016] Advantages of the present utility model:

[0017] In the present utility model, whether the kettle body is in a flat state or a pouring state, the opening of the exhaust passage is above the liquid level. From beginning to end, the liquid level will not contact the exhaust hole, so the exhaust hole will not be blocked;

[0018] During the pouring process, the kettle body tilts. Due to the setting of the exhaust passage, the liquid level will not contact the exhaust hole. At this time, external air can enter the exhaust passage from the exhaust hole and finally enter the inner cavity of the kettle body from the vicinity of the exhaust passage, which can ensure normal water discharge and will not cause water to flow out from the exhaust hole;

[0019] When using the kettle body to boil water, the water vapor generated in the inner cavity of the kettle body can enter the exhaust passage from the opening and finally be discharged from the exhaust hole. Based on the above embodiments, a large pressure will be generated in the kettle body during the pouring process. Since the boiling water will not block the exhaust hole, normal steam discharge can be achieved, and there will be no situation where boiling water sprays out from the exhaust hole, avoiding accidents.

[0020] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation part. Brief Description of the Drawings

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0031] Please refer to Figures 1-8 ;

[0032] The portable kettle of the present utility model aims to solve the problems that the water blocks the exhaust hole 3 during pouring, resulting in abnormal exhaust and poor water discharge. It should be noted that although the handle 13 kettle is taken as an example in the background art for illustration, whether it is a handle 13 kettle or a side handle kettle, the present technical solution can be equally applied; specifically, it includes a kettle body 1. Preferably, a handle 13 is provided at the upper end of the kettle body 1. The design with the handle 13 is labor-saving and convenient for carrying. Of course, the kettle body 1 should include a kettle body 11 and a kettle lid 12, and the kettle body 11 and the kettle lid 12 are connected by a locking structure. In this embodiment, the installation position of the handle 13 is not limited, that is, it can be connected to the kettle body 11 or the kettle lid 12. No matter which component the handle 13 is connected to, a fixed connection method is preferably adopted, that is, the handle 13 cannot rotate or displace, so that it will not shake during pouring and is very stable. In addition, a baffle is provided at the water injection port of the kettle body 11 to prevent the water in the inner cavity from overflowing from the opening 42 between the kettle body 11 and the kettle lid 12; an exhaust hole 3 is provided at the position of the kettle body 1 corresponding to the spout 2, that is, the exhaust hole 3 and the spout 2 are arranged on the same side. Preferably, the exhaust hole 3 is provided on the center line of the spout 2. Based on the prior art, the liquid will block the exhaust hole 3 during pouring. Therefore, in this embodiment, an exhaust passage 41 communicating with the exhaust hole 3 is provided in the inner cavity of the kettle body 1, and the exhaust passage 41 is provided with an opening 42, and the opening 42 is always above the liquid level; in other words, no matter whether the kettle body 1 is in a flat state or a pouring state, the opening 42 of the exhaust passage 41 is above the liquid level, and the liquid level will never contact the exhaust hole 3 from beginning to end, so that the exhaust hole 3 will not be blocked; of course, a prompt for the highest water level should be set in the kettle body 1. When the highest water level is exceeded, the function may fail. Therefore, the above effects play a role in normal use scenarios.

[0033] The above-mentioned "the opening 42 of the exhaust passage 41 is always above the liquid level" has various implementation manners, which will be described in detail below. During the pouring process, the kettle body 1 is tilted. Due to the setting of the exhaust passage 41, the liquid level will not contact the exhaust hole 3. At this time, external air can enter the exhaust passage 41 from the exhaust hole 3 and finally enter the inner cavity of the kettle body 1 from the exhaust passage 41, which can ensure normal water discharge and will not cause water to flow out from the exhaust hole 3;

[0034] When using the kettle body 1 to boil water, the water vapor generated in the inner cavity of the kettle body 1 can enter the exhaust passage 41 from the opening 42 and finally be discharged from the exhaust hole 3. Based on the above implementation manner, a large pressure will be generated in the kettle body 1 during the pouring process. Since the boiling water will not block the exhaust hole 3, normal steam discharge can be achieved, and there will be no situation where boiling water sprays out from the exhaust hole 3, avoiding accidents.

[0035] The following will describe the setting method of the exhaust passage 41 in detail;

[0036] In the above embodiments, there is no limitation on the position where the exhaust hole 3 is provided. That is, the exhaust hole 3 can be provided in the upper part or the lower part. It is a common practice to provide the exhaust hole 3 in the upper part of the kettle body 1, but it does not exclude the way of setting it in the lower part of the kettle body 1. When the exhaust hole 3 is provided in the lower part of the kettle body 1, that is, below the liquid level, a exhaust pipe is needed for the exhaust passage at this time. One end of the exhaust pipe is connected to the exhaust hole, and the other end extends upward to the upper part of the kettle body. By adopting such a way, it is also possible to ensure that the opening is always above the liquid level. However, using this design may cause poor steam discharge when boiling water, so it is not an optimal solution;

[0037] When the exhaust hole 3 is provided in the upper part of the kettle body 1 in the conventional way, referring to Figure 3 , in one of the embodiments, an exhaust pipe 44 is also used. One end of the exhaust pipe 44 is connected to the exhaust hole 3, and the other end extends into the inner cavity of the kettle body 1, preferably inclined upward. By adopting such a way, it is also possible to ensure that the opening 42 is always above the liquid level. However, when using the exhaust pipe 44, its opening 42 is relatively small, and it may cause poor steam discharge when boiling water.

[0038] When the exhaust hole 3 is provided in the upper part of the kettle body 1 in the conventional way, referring to Figure 4 , in another embodiment, a shielding member 43 is fixedly provided along the upper edge of the inner cavity of the kettle body 1. When the inner cavity of the kettle body 1 is circular, the shielding member 43 is arc-shaped to adapt to its upper edge. The shielding member 43 covers the exhaust hole 3 and encloses an exhaust passage 41 with the inner wall of the kettle body 1. The formed opening 42 is located along the upper edge of the inner cavity of the kettle body 1, and the shielding member 43 is relatively long. When the kettle body 1 is tilted to pour water, the opening 42 is still above the liquid level. By enclosing in such a way, the inner diameter of the exhaust passage 41 can be made larger, which is more conducive to gas exchange and does not occupy too much space, and the design is more reasonable.

[0039] Based on the embodiment of the shielding member 43, a common problem will occur. During the process of steam discharge, condensed water will be formed in the exhaust passage 41 and cannot be discharged. When boiling water again, there is a possibility of spraying the water accumulated in the drainage passage, which poses a safety hazard. Therefore, in this embodiment, the bottom surface of the inner wall of the shielding member 43 is designed to be inclined downward from the exhaust hole 3 to the opening 42 position. When condensed water is formed in the exhaust passage 41 by water vapor, it will slide along the inclined direction into the inner cavity, thus avoiding the situation of condensed water accumulation;

[0040] Furthermore, referring to Figure 5 , the exhaust hole 3 penetrates the side wall of the kettle body 1. When the position where the exhaust hole 3 is provided has a certain thickness, the exhaust hole 3 will have a certain length, so condensed water may also be formed. Therefore, the exhaust hole 3 is designed to be inclined downward, which can make the condensed water slide into the exhaust passage 41 and then slide into the inner cavity from the exhaust passage 41.

[0041] In the present utility model, a storage structure is provided between the spout 2 and the kettle body 1. The specific storage structure can be a rotary type. That is, originally, the spout 2 and the kettle body 1 are two independent components. One end of the spout 2 is rotatably connected to the kettle body 1. When not in use, the spout 2 can be rotated to be stored in the kettle body 1 to form a whole, thus saving space. For example, the related structures mentioned in the previously filed patent applications "2024217224225, a portable outdoor kettle" and "2024214074404, a kettle with a small volume and a fixed handle 13".

[0042] Another storage method is proposed in the present utility model. Refer to Figures 6-8 , which specifically includes a connection port. The spout 2 is inserted through the connection port, and a waterproof rubber sleeve 51 is provided between the spout 2 and the connection port. It should be noted that when in the storage state, it is recommended to pour out the water in the kettle body 1 to avoid water leakage. The spout 2 is movably connected to the kettle body 1. Only need to push the spout 2 into the inner cavity of the kettle body 1, which is very convenient. At this time, there is no protrusion on the side wall of the kettle body 1, and it is very flat. When in use, before injecting water, reach into the inner cavity of the kettle body 1 with your hand and push the spout 2 out of the inner cavity. In this embodiment, there is no restriction on both ends of the spout 2. Specifically, it is in a tubular shape, and the spout 2 can be completely pulled out for cleaning. In this embodiment, it is preferably to fix the waterproof rubber sleeve 51 at the connection port.

[0043] In the present utility model, the spout 2 includes a water passing part 21. One end of the water passing part 21 is provided with a first limiting part 22. The first limiting part 22 can abut against the inner cavity of the kettle body 1. In this embodiment, the spout 2 cannot be completely pulled out from the connection port. When in use, the first limiting part 22 abuts against the inner cavity. Preferably, the waterproof rubber sleeve 51 extends into the inner cavity. At this time, the first limiting part 22 can abut against the waterproof rubber sleeve 51.

[0044] Based on the further expansion of the above embodiment, a storage groove 52 is provided at the connection port. The other end of the water passing part 21 is provided with a second limiting part 23. The second limiting part 23 can enter the storage groove 52. The inner cavity width of the storage groove 52 is larger than the connection port, and the width of the second limiting part 23 is also larger than the connection port. Therefore, the second limiting part 23 can enter the storage groove 52 but cannot pass through the connection port.

[0045] Furthermore, the storage groove 52 is arranged to slope downward and extend into the inner cavity of the kettle body 1. When in the storage state, one still needs to reach into the inner cavity of the kettle body 1 to push out the spout 2. If the kettle body 1 is relatively small, it is difficult to reach one's hand into it, making it very difficult to operate. Therefore, a push-out spring 53 is provided in the storage groove 52. The push-out spring 53 abuts against the second limiting part 23 and is used to push it out of the storage groove 52. The push-out spring 53 is relatively short and is only located in the storage groove 52. When in the storage state, the push-out spring 53 is in a compressed state, and then the outlet of the storage groove 52 can be covered with the cover body 54. When in use, the cover body 54 is opened, and the push-out spring 53 will push the second limiting part 23 out of the storage groove 52. At this time, people can pinch the second limiting part 23 with their hands and pull out the spout 2, and the operation is very convenient.

[0046] Preferably, a sliding groove 55 is provided on the side wall of the kettle body 1. The cover body 54 is provided with a connecting part 56 which is slidably connected to the sliding groove 55, and the cover body 54 and the kettle body 1 can be detachably fixed. The specific detachable connection method can be that a clamping groove is provided on the end face of the cover body 54, and a clamping bar is provided on the side wall of the kettle body 1, so as to achieve detachable connection. When unlocking is required, the elastic deformation of the plastic can be used to achieve decoupling.
