Description

Technical Field

[0001] This disclosure relates to the field of experimental equipment technology, and in particular to a funnel device. Background Technology

[0002] Laboratory waste liquid recycling is common in research institutes, universities, and testing units. The recycling process involves pouring waste liquid into waste liquid containers. Currently, the commonly used waste liquid funnels in laboratories are ordinary funnels, which are inserted into the waste liquid container to connect to it. However, this method is not stable; when pouring waste liquid into the container, the funnel may tilt, causing spillage and environmental pollution. Due to the frequent pouring during experiments, for the sake of convenience, researchers cannot remove the funnel and tighten the container lid after each pour, thus posing a risk of waste liquid evaporating into the atmosphere. Furthermore, for some highly viscous, poorly flowing samples, there is a certain amount of time required for the liquid to flow from the funnel into the waste liquid container. An open waste liquid funnel exposes the sample directly to the air, which will have adverse effects on human health and the environment in the long run. Summary of the Invention

[0003] A primary objective of this disclosure is to overcome at least one of the deficiencies of the prior art described above, and to provide a funnel device that can be stably connected to a container and prevent material leakage.

[0007] According to one embodiment of this disclosure, the mesh is located at the connection between the first part and the second part.

[0008] According to one embodiment of this disclosure, the bottom of the funnel body is connected to a downwardly extending discharge pipe, the discharge port is disposed at the lower end of the discharge pipe, and the sealing member passes through the discharge pipe.

[0009] According to one embodiment of this disclosure, the outer wall of the discharge pipe is provided with an external thread, which is used to engage with the internal thread of the container's inlet.

[0010] According to one embodiment of this disclosure, the sealing block is a frustum-shaped structure, with the larger end of the frustum-shaped structure facing downwards; when the sealing member is in the first position, the inclined conical surface of the sealing block is in a sealing fit with the discharge port.

[0012] According to one embodiment of this disclosure, the fastener is an adjustable-length fixing ring, a binding rope, or a clamp.

[0013] According to one embodiment of this disclosure, a cap is provided on the top of the funnel body, the cap being detachably or adjustablely connected to the funnel body for sealing the feed inlet.

[0014] As can be seen from the above technical solution, the advantages and positive effects of the funnel device proposed in this disclosure are as follows: The funnel device disclosed herein includes a funnel body, a sealing element, and a fixing arm. The funnel body has a feed inlet at the top and a discharge outlet at the bottom. The sealing element is vertically and vertically mounted on the funnel body and can switch between a first position and a second position.

[0019] See Figure 1 The diagram illustrates, in a representative manner, the structure of the funnel device 100 proposed in this disclosure. A perspective view is used to show some of the internal structures of the funnel body 110, such as the sealing element 120 and the strainer 140. In this exemplary embodiment, the funnel device 100 proposed in this disclosure is described as a liquid collecting funnel used for the collection and recovery of laboratory waste liquid. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below to apply the relevant designs of this disclosure to application scenarios of other types of materials. These changes are still within the scope of the principles of the funnel device 100 proposed in this disclosure.

[0020] like Figure 1 As shown, in one embodiment of this disclosure, the funnel device 100 includes a funnel body 110, a sealing member 120, and a fixing arm 130. (See also...) Figures 2 to 5 , Figure 2 A schematic plan view of the mesh 140 is shown in the figure. Figure 3 and Figure 4The diagram shows enlarged partial views of the funnel device 100 in two different states, representing its representative characteristics. Figure 3 The structure of the sealing element 120 in the first position is shown in detail. Figure 4 The structure of the sealing element 120 in the second position is shown in detail; Figure 5 The diagram shows a representative example of the use state of the fixing member 131 when it is fixed to the inlet 210 of the container. The structure, connection method, and functional relationship of the main components of the funnel device 100 proposed in this disclosure will be described in detail below with reference to the above-mentioned figures.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the funnel body 110 has a feed inlet 111 at its top and a discharge outlet 112 at its bottom. The sealing member 120 is vertically and flexibly mounted on the funnel body 110, and can switch between a first position and a second position. A sealing block 121 is provided at the lower end of the sealing member 120, such as... Figure 3 As shown, when the sealing element 120 is in the first position, the sealing block 121 seals the outlet 112, thereby maintaining the seal of the outlet 112 of the funnel device 100 and preventing volatile materials (such as waste liquid) in the container from evaporating into the atmosphere through the funnel device 100. Figure 4 As shown, when the sealing element 120 is in the second position, the sealing block 121 is spaced apart from the discharge port 112, thus opening the discharge port 112. The fixing arm 130 is connected to the funnel body 110. The fixing arm 130 is provided with a fixing element 131, which is used to adjustably connect to the inlet 210 of the container. Through the above structural design, this disclosure utilizes the sealing element 120 to adjustably block or open the discharge port 112 of the funnel body 110. Accordingly, when no material is being added to the container, the sealing element 120 can be used to block the discharge port 112, ensuring the container is sealed and preventing material leakage, without the need to immediately remove the funnel device 100 after each filling. Furthermore, this disclosure utilizes the fixing arm 130 and the fixing element 131 to ensure the stability and reliability of the connection between the funnel device 100 and the container, avoiding problems such as tilting of the funnel device 100 and material spillage caused by loose connection during the filling process. In addition, the funnel device 100 disclosed herein can be widely used in various types of laboratories, and has a wide range of applications.

[0022] like Figure 1 and Figure 2As shown, in one embodiment of this disclosure, a funnel body 110 may be provided with a mesh 140. Based on this, a sealing member 120 can be connected to the mesh 140 via a push-button mechanism 150. The push-button mechanism 150 is provided with a button located above the mesh 140. This button is used by the user to operate the sealing member 120 relative to the mesh 140, causing it to rise and fall, and switch between a first position and a second position. Specifically, the push-button mechanism 150 can adopt an elastic pressing and resetting mechanism. For example, pressing the button once causes the push-button mechanism 150 to move the sealing member 120 down to the second position, opening the discharge port 112. Pressing the button again releases the elastic restoring force of the elastic element inside the push-button mechanism 150, causing the push-button mechanism 150 to move the sealing member 120 up, returning it to the first position, and closing the discharge port 112 again. Through the above structural design, this disclosure can achieve a reliable push-to-switch function, making the switching operation of closing and opening the discharge port 112 more convenient. In addition, this disclosure utilizes the strainer 140 to make the process of material falling to the discharge port 112 more uniform. For example, for waste liquid with poor flowability, the pouring speed is slow, and residue is easily left in the container; direct washing may cause water pollution. In this case, the container can be inverted on the strainer 140, i.e., the container opening is placed downwards on the funnel device, the cap 160 is covered, and it is left to stand for a period of time until the waste liquid slowly flows out. At the same time, the cap 160 can reduce the evaporation of waste liquid into the atmosphere, so that the waste liquid can flow out of the container, flow into the funnel device, and then into the waste liquid bucket. In other embodiments of this disclosure, other types of push-to-switch structures can also be used to achieve the switching function of the sealing member 120 between the first and second positions, and this disclosure is not limited to this embodiment.

[0023] like Figure 1 As shown, based on the structural design of the sealing member 120 connected to the strainer 140 via the snap-action mechanism 150, in one embodiment of this disclosure, the funnel body 110 may include a first part 113 and a second part 114. The first part 113 is a cylindrical structure, with the inlet 111 located at the top of the first part 113. The second part 114 is a conical cylindrical structure, connected to the bottom of the first part 113, with the larger end of the conical shape facing upwards, and the outlet 112 located at the bottom of the second part 114. Based on this, the sealing member 120 can be connected to the center position of the strainer 140 via the snap-action mechanism 150.

[0024] like Figure 1As shown, based on the structural design of the funnel device 100 including the strainer 140, in one embodiment of this disclosure, the strainer 140 can be located at the connection between the first part 113 and the second part 114. Through the above structural design, this disclosure enables the strainer 140 to be arranged closer to the discharge port 112, which is beneficial to shorten the length of the sealing member 120, facilitates the structural arrangement, facilitates the snap-action lifting and lowering switching function of the snap-action mechanism 150, and also enables the second part 114 to realize the lower limit function of the strainer 140.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the bottom of the funnel body 110 (e.g., the bottom of the second part 114) can be connected to a downwardly extending discharge pipe 115. The discharge port 112 of the funnel body 110 can be located at the lower end of the discharge pipe 115, and the sealing member 120 can pass through the discharge pipe 115. Through the above structural design, this disclosure can utilize the discharge pipe 115 to connect with the inlet 210 of the container, thereby improving the stability of the connection between the funnel device 100 and the container. In addition, this disclosure can utilize the discharge pipe 115 to guide the sealing member 120, ensuring the stability and accuracy of the sealing member 120 during its lifting and lowering movement, and ensuring the sealing effect.

[0026] In one embodiment of this disclosure, the outer wall of the discharge pipe 115 may be provided with external threads, which are used to mate with the internal threads of the container's inlet 210. Through the above structural design, this disclosure can further improve the stability of the connection between the funnel device 100 and the container. It should be noted that when the container's inlet 210 is not provided with internal threads, the outer wall of the discharge pipe 115 may not be provided with external threads, or when the container's inlet 210 is provided with internal threads, the outer wall of the discharge pipe 115 may also not be provided with external threads, that is, the connection between the funnel device 100 and the container is achieved only through the fixing member 131, and is not limited to this embodiment.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, the sealing block 121 can be a frustum-shaped structure, with the larger end of the frustum facing downwards. When the sealing member 120 is in the first position, the inclined conical surface of the sealing block 121 seals against the discharge port 112. Through the above structural design, this disclosure can further optimize the sealing effect of the sealing block 121 on the discharge port 112. In other embodiments of this disclosure, the sealing block 121 can also adopt other structural shapes, such as spherical or ellipsoidal, and is not limited to this embodiment.

[0028] like Figure 1As shown, in one embodiment of this disclosure, the fixing arm 130 can be connected to the side of the funnel body 110 (e.g., the side of the first part 113) and extends downward, with the lower end of the fixing arm 130 extending to a position corresponding to the discharge port 112. The fixing member 131 is connected to the lower end of the fixing arm 130 and extends to the discharge port 112.

[0029] like Figure 1 and Figure 5 As shown, in one embodiment of this disclosure, the fixing member 131 can be an adjustable-length binding rope, which is sleeved around the outer periphery of the container's inlet 210 and can be fixed by a buckle 132 after adjusting to a suitable length, thereby connecting the funnel device 100 to the container and adapting to the outlet 112 of various containers of different sizes or shapes. In other embodiments of this disclosure, the fixing member 131 can also be other structures, such as, but not limited to, adjustable-length fixing rings, clamps, etc., and is not limited to this embodiment.

[0030] like Figure 1 As shown, in one embodiment of this disclosure, a cap 160 may be provided on the top of the funnel body 110. The cap 160 is detachably or adjustablely connected to the funnel body 110 and is used to close the feed inlet 111. Through the above structural design, this disclosure utilizes the cap 160 to achieve free opening and closing of the feed inlet 111. When the funnel device 100 is idle or when pouring waste liquid with poor flowability, the cap 160 can be closed to reduce the evaporation of waste liquid into the air.

[0031] In one embodiment of this disclosure, the funnel body 110 may be made of an acid- and alkali-resistant, corrosion-resistant material.

[0032] In one embodiment of this disclosure, the sealing element 120 and the sealing block 121 may be made of acid- and alkali-resistant and corrosion-resistant materials.

[0033] In one embodiment of this disclosure, the mesh 140 may be made of an acid- and alkali-resistant, corrosion-resistant material.

[0034] In one embodiment of this disclosure, the fixing arm 130 and the fixing ring may be made of acid- and alkali-resistant and corrosion-resistant materials.

[0035] In one embodiment of this disclosure, the cap 160 may be made of an acid- and alkali-resistant, corrosion-resistant material.

[0036] It should be noted that the funnel device 100 shown in the accompanying drawings and described in this specification is merely a few examples among many funnel devices 100 capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the funnel device 100 shown in the accompanying drawings or described in this specification.

[0037] In summary, the funnel device 100 disclosed herein includes a funnel body 110, a sealing member 120, and a fixing arm 130. The funnel body 110 has a feed inlet 111 at the top and a discharge outlet 112 at the bottom. The sealing member 120 is vertically and vertically mounted on the funnel body 110 and can switch between a first position and a second position. A sealing block 121 is provided at the lower end of the sealing member 120. When the sealing member 120 is in the first position, the sealing block 121 blocks the discharge outlet 112. When the sealing member 120 is in the second position, the sealing block 121 and the discharge outlet 112 are spaced apart to open the discharge outlet 112. The fixing arm 130 is connected to the funnel body 110. The fixing arm 130 is provided with a fixing member 131, which is adjustablely connected to the feed inlet 210 of the container. Through the above structural design, this disclosure utilizes the sealing component 120 to adjustably seal or open the discharge port 112 of the funnel body 110. Therefore, when no material is being added to the container, the sealing component 120 can be used to seal the discharge port 112, ensuring the container's closure and preventing material leakage, eliminating the need to immediately remove the funnel device 100 after each filling. Furthermore, this disclosure utilizes the fixing arm 130 and the fixing component 131 to ensure the stability and reliability of the connection between the funnel device 100 and the container, avoiding problems such as tilting of the funnel device 100 and material spillage during the filling process due to insecure connection.
