Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] It is to be understood that the terms so far as the language goes are used herein only to describe specific embodiments and not intended to limit the example embodiments according to the present application. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, devices, components, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, steps, operations, devices, components, and / or combinations thereof.

[0022] The relative arrangement of parts and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise. At the same time, it should be clear that the sizes of the various parts shown in the drawings are not drawn in accordance with the actual proportional relationship for the convenience of description. The techniques, methods and devices known to those skilled in the related art can not be discussed in detail, but in appropriate cases, the techniques, methods and devices should be considered as part of the authorized description. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the example embodiments can have different values. It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and in the absence of the opposite description, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the scope of protection of the present application: the orientation words "inner, outer" refer to the inner and outer of the contour of each component.

[0026] As Figure 1 shown, the utility model provides a kind of novel pressure relief filter funnel device, including bowl 1 and the bowl 1 with the communication of funnel diameter 2;

[0027] Groove 3 is opened in the outer surface near the connection of the bowl 1 and the funnel diameter 2;The funnel outlet of the bottom of the funnel diameter 2 is beveled, and the groove is located on the other side opposite to the side where the beveled tip A point is located on the funnel device.

[0028] Further, the groove 3 extends from the bottom of the bowl 1 to the top of the funnel diameter 2.

[0029] Further, the width d of the groove 3 is 5mm, and the depth h is 2mm.

[0030] Further, the size of the groove 3 can be adjusted according to actual needs, and the funnel should be avoided to be broken during production and processing.

[0031] When the funnel device is used for filtering, the groove 3 falls exactly at the connection of the bowl and the funnel neck and is connected with the lower collecting device, which can communicate the filtrate collecting device with the atmosphere, ensure that the filtrate is smoothly drained to the filtrate collecting device, avoid the sealing caused by the close contact or liquid infiltration between the funnel and the filtrate collecting device, so as to realize the rapid and efficient filtering operation.

[0032] Figure 2 And Figure 3For the practical application of the funnel device described in this utility model, when the filtrate collection device is a volumetric flask ( Figure 2 ) or conical flask ( Figure 3 When the grooves are present, the filtrate collection device is effectively kept out of contact with the atmosphere, so the filtrate can be efficiently guided into the collection device, which can effectively improve the laboratory filtration efficiency.

[0033] The practical application effect of the funnel device described in this utility model will be explained below with reference to Examples 1-3.

[0034] Example 1

[0035] When using ICP-OES to detect elements such as potassium and sodium in ore pellets, the pellets contain acid-insoluble substances, requiring filtration to obtain the filtrate for testing. This filtration process often involves slow-speed filter paper filtration. The funnel device described in this invention can quickly complete the filtration.

[0036] Example 2

[0037] ICP-OES is used to detect elements such as chromium, iron, and nickel in titanium dioxide slurry. The number of samples is large, and there are time constraints for the detection. The test solution must be clear. Titanium dioxide slurry is turbid and viscous. At least two layers of slow-speed filter paper are required for filtration. The funnel device described in this invention completely avoids the problems of filtrate leakage or repeated filtration caused by the sealing of the funnel without grooves in the past. It also greatly shortens the time for batch filtration operations, allowing the testers to issue data reports in a timely manner.

[0038] Example 3

[0039] When ICP-OES is used to detect toxic and harmful elements such as arsenic and chromium in environmental soil samples, the samples appear turbid after shaking treatment and require dry filtration. The funnel device described in this invention can achieve rapid filtration and improve detection efficiency.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
