Abstract
Description
Technical Field
[0001] The utility model belongs to the field of waste liquid recovery, and in particular relates to a waste liquid container and a sealing device. Background Art
[0002] As people's environmental awareness gradually increases, more and more industries and regions begin to emphasize environmental protection operations to avoid environmental pollution. In the process of environmental protection operations, in order to avoid leakage of waste liquid, safe storage of waste liquid is essential. Conventional waste liquid includes but is not limited to waste oil, waste paint, waste banana oil and waste water, etc.
[0003] In conventional means, when storing waste liquid, the waste liquid is usually stored in a container, which can be a rectangular or cylindrical container. At the same time, since some waste liquids (e.g., waste banana water) are volatile, they will release irritating odors, causing severe discomfort to the human body and causing greater environmental pollution. Therefore, in order to reduce the discomfort caused by irritating gases to the human body and reduce environmental pollution, the prior art often provides components such as a closed cover at the mouth of the container to prevent the irritating gases from being released into the outside world.
[0004] However, users have found in practice that, since waste liquid needs to be frequently put into the container and the cover needs to be frequently opened and closed, the sealing cover configured on the container often deforms after a period of use, thereby making it unable to block the leakage of irritating gas. At the same time, since some sealing covers have poor sealing performance, they are also unable to prevent the leakage of irritating gas.
[0005] In summary, the problem of irritant gas leakage needs to be solved urgently in the prior art. Utility Model Content

[0008] The connecting channel is provided with a closing plug, which can block the connecting channel. A closing cover is arranged on the top of the closing component, which can close the entrance of the closing component.
[0009] In this solution, the interior of the container body is used to contain waste liquid. At the same time, a sealing component is installed at the mouth of the container body, and the sealing component is equipped with a sealing plug and a sealing cover. The sealing plug and the sealing cover perform two-layer sealing of the irritating gas, thereby solving the problem of irritating gas leakage.

[0017] Preferably, in order to realize the automation of the sealing plug, that is, when waste liquid needs to be introduced, the sealing plug opens the connecting channel, and when the leakage of irritating gas needs to be blocked, the sealing plug blocks the connecting channel. In this solution, the lifting structure preferably also includes a spring, and the two ends of the spring are respectively matched with the mounting component and the bracket, and the spring can drive the sealing plug to rise, and the top of the mounting component is in transmission cooperation with the sealing cover;
[0018] When the closure cover is in a closed state, the closure cover presses down the installation component so that the closure plug blocks the connection channel. When the closure cover is in an open state, the spring drives the installation component to rise so that the closure plug opens the connection channel.
[0019] In this solution, when the waste liquid needs to be introduced into the container body, the closing plug is driven up by the spring and the connecting channel is opened. After the waste liquid is loaded, the closing plug is closed on the top of the closing component, the closing component presses the installation component down, and the closing plug blocks the connecting channel to prevent the leakage of irritating gas.
[0020] Preferably, in order to enable the waste liquid to be introduced into the interior of the containing component, the sealing component is preferably a funnel in this solution.
[0021] In this solution, the funnel can receive more waste liquid and guide the waste liquid into the container body. Compared with other structures, the funnel has a higher efficiency in guiding waste liquid.

[0043] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.
[0044] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the location and with the authorization given by the owner of the corresponding device.
[0045] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.
[0046] Example 1
[0047] Basically as attached Figure 1 To Attachment Figure 2 As shown, the waste liquid container is used to contain the waste liquid and prevent the irritating gas released by the waste liquid from leaking to the outside.
[0048] The waste liquid that can be contained in the waste liquid container in the embodiment of the present disclosure includes but is not limited to waste oil, waste paint, waste banana oil, waste water, etc.
[0049] like Figure 1 and Figure 2 As shown, the waste liquid container in the disclosed embodiment includes a container body 1 and a closing component 2, and the container body 1 is preferably a storage barrel. The storage barrel can be a round barrel or a rectangular barrel. The top of the storage barrel is configured with a round mouth, so that the waste liquid outside can be loaded into the storage barrel through the mouth. Of course, since the mouth is connected to the outside, the irritating gas inside the storage barrel will also leak from the mouth.
[0050] In the embodiment of the present disclosure, a closing component 2 is installed at the mouth of the container body 1. The closing component 2 is preferably a funnel, and a conical connecting channel is configured inside the funnel. When the closing component 2 is installed at the mouth of the container body 1, waste liquid from the outside can enter the inside of the container body 1 through the connecting channel. At the same time, the irritating gas inside the container body 1 can also leak from the connecting channel to the outside.
[0051] like Figure 1 and Figure 2 As shown, in the disclosed embodiment, the funnel is detachably mounted on the mouth of the container body 1, so that after the container body 1 is filled with waste liquid, the funnel can be removed from the container body 1, and then the container body 1 can be taken away separately. In order to achieve the detachable installation of the funnel on the container body 1, a sealing ring can be provided on the surface or inside the mouth of the funnel in the disclosed embodiment, such as a sealing rubber ring. Then, the funnel can be directly inserted into the mouth of the receiving component. The sealing at the mouth is achieved by the sealing ring, and then the funnel can be pulled out to achieve a detachable connection.
[0052] Take an application scenario as an example: when waste liquid needs to be injected, the funnel is inserted into the mouth of the container body 1, so that the waste liquid from the outside can enter the container body 1 through the inside of the funnel. When the waste liquid inside the container body 1 is full, just pull out the funnel, so that the container body 1 can be moved alone.
[0053] In the embodiment of the present disclosure, a closing plug 3 is provided inside the closing component 2, and the closing plug 3 is cone-shaped as a whole. The closing plug 3 can be made of rubber, and it can completely block the connecting channel by deformation, so that the irritating gas inside the container body 1 cannot leak from the connecting channel to the outside. At the same time, in the embodiment of the present disclosure, a closing cover 4 is installed on the top of the closing component 2, and the closing cover 4 is a circular cover body. The closing cover 4 can be directly buckled on the top of the closing component 2, so that the entrance of the closing component 2 is blocked. Of course, in some embodiments, the closing cover 4 can be installed on the top of the closing component 2 by a hinge, and the closing cover 4 rotates, and the closing cover 4 closes and opens the top of the closing component 2.
[0054] It can be understood that: in the disclosed embodiment, the closing plug 3 and the closing cover 4 are used, and the closing plug 3 realizes the first layer of blocking of the enclosed gas to prevent the irritating gas in the container body 1 from diffusing to the upper end of the closing component 2; then the closing plug 3 realizes the second layer of blocking of the irritating gas to prevent the irritating gas from leaking to the outside. Obviously, through the two layers of blocking of the closing plug 3 and the closing cover 4, the probability of the irritating gas leaking to the outside will be greatly reduced, and the effect of preventing the leakage of the irritating gas will be better. At the same time, when the closing cover 4 is deformed due to long-term use, due to the first layer of blocking of the closing plug 3, a large amount of irritating gas will not leak into the external environment.
[0055] In the embodiment of the present disclosure, the sealing plug 3 is connected to the lifting structure, and the sealing plug 3 realizes the lifting movement through the lifting structure. When the sealing plug 3 descends, the sealing plug 3 can block the connecting channel, such as Figure 1 When the closing plug 3 rises, the closing plug 3 opens the connecting channel, as shown in FIG. Figure 2 shown.
[0056] The lifting structure described in the embodiment of the present disclosure includes a mounting component 5, a bracket 6 and a spring 7. The mounting component 5 can be a connecting rod or a connecting column. The sealing plug 3 is installed at the bottom of the mounting component 5. When it is implemented, it can be installed by existing installation methods such as bonding or interlocking. After the mounting component 5 is connected to the sealing plug 3, when the mounting component 5 moves up and down, the sealing plug 3 will obviously also move up and down. Figure 3As shown, the bracket 6 in the embodiment of the present disclosure can be a support rod, which is horizontally installed inside the closing component 2, and the two ends of the support rod are welded to the inside of the closing component 2. At the same time, a vertical constraint channel is constructed in the middle of the support rod, and the installation component 5 is accommodated inside the constraint channel. The constraint channel is used to fix the installation component 5 to prevent the installation component 5 from tipping over; at the same time, the constraint channel can also play a guiding role to ensure that the closing plug 3 moves accurately to the position where the connecting channel is blocked, and also prevent the installation component 5 from deflecting when the lifting movement occurs. In the embodiment of the present disclosure, the spring 7 is preferably arranged at the top of the bracket 6, and the two ends of the spring 7 are respectively matched with the top of the bracket 6 and the upper end of the installation component 5. During implementation, the two ends of the spring 7 can be respectively welded to the top of the bracket 6 and the upper end of the installation component 5. A matching block is arranged at the upper end of the installation component 5 and connected to the spring 7. In the embodiment of the present disclosure, the spring 7 is mainly used to bounce the installation component 5 so that the closing plug 3 is in a state of opening the connecting channel. At the same time, when the installation component 5 bounces up, the top of the installation component 5 is higher than the top of the closing component 2. Therefore, when the closing cover 4 is closed on the top of the closing component 2, the bottom of the closing cover 4 will contact the top of the mounting component 5, so as to press down the mounting component 5. When the mounting component 5 is pressed down, the closing plug 3 can move to block and close the connecting channel (at this time, the spring 7 is in a compressed state).
[0057] Take an application scenario as an example: when the closing cover 4 is opened, the mounting component 5 is bounced up by the spring 7, and the closing plug 3 opens the connection channel. At this time, the external waste liquid can enter the container body 1 through the connection channel. When the closing cover 4 is closed to the top of the closing component 2, the closing cover 4 presses the mounting component 5 downward, so that the closing plug 3 blocks the connection channel.
[0058] It should be noted that: in the embodiment of the present disclosure, the closing component 2 is a funnel, but in some other embodiments, the closing component 2 may not be a funnel. Figure 4 As shown, for example, the closing component 2 is cylindrical in shape, and a stepped connecting channel is constructed inside the closing component 2. The closing plug 3 is located at the upper part of the channel. When the closing plug 3 moves downward, the closing plug 3 blocks the connection between the upper part of the channel and the lower part of the channel, and the connecting channel is blocked.
[0059] Example 2
[0060] The difference between the embodiment of the present disclosure and embodiment 1 is that Figure 5 As shown, the embodiment of the present disclosure does not include a spring 7. Therefore, in the embodiment of the present disclosure, the mounting component 5 cannot spring up, but the mounting component 5 can drop under the action of gravity, so that the closing plug 3 blocks the connecting channel.
[0061] Take an application scenario as an example: when waste liquid needs to be loaded into the container body 1, the user manually opens the closing cover 4 and lifts the mounting component 5 so that the closing plug 3 opens the connecting channel. When the waste liquid is loaded, the closing plug 3 drops under the action of gravity to block the connecting channel. At the same time, the closing cover 4 is manually closed.
[0062] Example 3
[0063] The disclosed embodiments provide a closure device such as Figure 6 As shown, it includes a closing component 2, a closing plug 3 and a closing cover 4. In the disclosed embodiment, the closing component 2 is used to be installed at the mouth of the container, and the interior of the container is used to accommodate waste liquid. The closing component 2 can be installed at the mouth of the container by welding, or it can be detachably installed at the mouth of the container by means of threads or the like. When the closing component 2 is installed at the mouth of the container, the closing component 2 closes the mouth of the container to solve the problem of irritating gas leakage from the mouth of the container. At the same time, when the closing component 2 is installed at the mouth of the container, waste liquid from the outside can enter the interior of the container from the connecting channel.
[0064] In the disclosed embodiment, the closed component 2 is preferably a funnel, and a connecting channel is configured inside the funnel. At the same time, a closed plug 3 is provided inside the closed component 2, and the closed plug 3 is cone-shaped as a whole. The closed plug 3 can be made of rubber, and it can completely block the connecting channel by deformation, so that the irritating gas cannot leak from the connecting channel to the outside world. At the same time, in the disclosed embodiment, a closed cover 4 is installed on the top of the closed component 2, and the closed cover 4 is a circular cover body. The closed cover 4 can be directly buckled on the top of the closed component 2, so that the entrance of the closed component 2 is blocked. Of course, in some embodiments, the closed cover 4 can be installed on the top of the closed component 2 by a hinge, and the closed cover 4 rotates, and the closed cover 4 closes and opens the top of the closed component 2.
[0065] It can be understood that: in the disclosed embodiment, the closing plug 3 and the closing cover 4 are used, and the closing plug 3 realizes the first layer of blocking of the enclosed gas to prevent the irritating gas in the container body 1 from diffusing to the upper end of the closing component 2; then the closing plug 3 realizes the second layer of blocking of the irritating gas to prevent the irritating gas from leaking to the outside. Obviously, through the two layers of blocking of the closing plug 3 and the closing cover 4, the probability of the irritating gas leaking to the outside will be greatly reduced, and the effect of preventing the leakage of the irritating gas will be better. At the same time, when the closing cover 4 is deformed due to long-term use, due to the first layer of blocking of the closing plug 3, a large amount of irritating gas will not leak into the external environment.
[0066] In the embodiment of the present disclosure, the closing plug 3 is connected to the lifting structure, and the closing plug 3 realizes lifting movement through the lifting structure. When the closing plug 3 descends, the closing plug 3 can block the connecting channel. When the closing plug 3 rises, the closing plug 3 opens the connecting channel.
[0067] The lifting structure described in the embodiment of the present disclosure includes a mounting component 5, a bracket 6 and a spring 7, and the mounting component 5 can be a connecting rod or a connecting column. The closing plug 3 is installed at the bottom of the mounting component 5. When it is implemented, it can be installed by existing installation methods such as bonding or interlocking connection. After the mounting component 5 is connected to the closing plug 3, when the mounting component 5 moves up and down, the closing plug 3 will obviously also move up and down. The bracket 6 in the embodiment of the present disclosure can be a support rod, which is horizontally installed inside the closing component 2, and the two ends of the support rod are welded to the inside of the closing component 2. At the same time, a vertical constraint channel is constructed in the middle of the support rod, and the mounting component 5 is accommodated inside the constraint channel. The constraint channel is used to fix the mounting component 5 to prevent the mounting component 5 from tipping over; at the same time, the constraint channel can also play a guiding role to ensure that the closing plug 3 moves accurately to the position where the connecting channel is blocked, and also prevent the mounting component 5 from deflecting when it moves up and down. In the embodiment of the present disclosure, the spring 7 is preferably arranged at the top of the bracket 6, and the two ends of the spring 7 are respectively matched with the top of the bracket 6 and the upper end of the mounting component 5. During implementation, the two ends of the spring 7 can be welded to the top of the bracket 6 and the upper end of the mounting component 5, respectively. A matching block is provided at the upper end of the mounting component 5 and is connected to the spring 7. In the disclosed embodiment, the spring 7 is mainly used to bounce the mounting component 5 so that the closing plug 3 is in a state of opening the connecting channel. At the same time, when the mounting component 5 is bounced, the top of the mounting component 5 is higher than the top of the closing component 2. Therefore, when the closing cover 4 is closed on the top of the closing component 2, the bottom of the closing cover 4 will contact the top of the mounting component 5, so that the mounting component 5 is pressed down. When the mounting component 5 is pressed down, the closing plug 3 can move to block and close the connecting channel (at this time, the spring 7 is in a compressed state).
[0068] Take an application scenario as an example: when the closing cover 4 is opened, the mounting component 5 is bounced up by the spring 7, and the closing plug 3 opens the connection channel. At this time, the external waste liquid can enter the container body 1 through the connection channel. When the closing cover 4 is closed to the top of the closing component 2, the closing cover 4 presses the mounting component 5 downward, so that the closing plug 3 blocks the connection channel.
[0069] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
