See fig. 1-3. The embodiment describes a multifunctional filtrate receiving cup, which comprises an upward-opening cylindrical cup body 100 and a cup cover 200 detachably mounted on the cup mouth. In the prior art, the cup lid 200 is mounted on the cup body 100 in many ways. In this application, the cup lid 200 includes an upper plate and a sidewall extending downward to a certain height, and the cup lid sidewall is embedded in the cup body. Set up like this, be convenient for receive the cup when shaking in the oscillator, perhaps receive the cup in the transportation, can not become flexible or by the mistake open, the safety in utilization of the cup is received in the abundant guarantee. Particularly, set up the external screw thread on the bowl cover lateral wall, set up the internal thread at the cup inner wall, cup and bowl cover threaded connection. When filtrate is received, the cup cover can be opened; after the filtrate is received, the cup cover is covered. The cup body 100 and the cup cover 200 can be made of light-transmitting materials or light-shielding materials. The filter is made of light-transmitting materials, such as glass and organic glass, so that the filtrate can be observed conveniently. Further, volume scales can be arranged on the cup body 100, so that the volume change of the filtrate can be calculated conveniently.

Referring to fig. 1 and 2, a filtrate outlet 103 is formed at the bottom of the cup body 100, and a safety valve 600 is assembled on the filtrate outlet 103. The safety valve 600 is used to open or close the filtrate outlet 103. The safety valve 600 is in a normally closed state, and the safety valve 600 is opened only by operating rules when filtrate is taken.

In the embodiment, a specific structure of the safety valve 600 is provided, the safety valve 600 is a concealed valve, and specifically, a safety valve mounting hole 106 which is staggered with the filtrate outlet 103 is formed in the bottom of the cup, and the safety valve is mounted in the safety valve mounting hole 106. In this embodiment, the safety valve mounting hole 106 is a through hole transversely penetrating through the bottom of the cup, the through hole may be divided into a spool mounting portion 1061, an adjusting screw mounting portion 1062 and a plug mounting portion 1063 according to the area relationship of the mounting parts, the adjusting screw mounting portion 1062 and the plug mounting portion 1063 are located at two ends of the spool mounting portion 1061, and the spool mounting portion 1061 intersects with the filtrate outlet 103.

An adjusting screw 602, a valve post 601 for opening or closing the filtrate outlet, a first spring 603 and a plug 604 are sequentially installed in the safety valve installation hole 106.

The spool 601 is in sliding fit with the safety valve mounting hole 106, specifically, the spool 601 is in seamless sliding fit with the spool mounting part 1061, that is, the side wall of the spool 601 is in seamless fit with the inner wall of the spool mounting part 1061. In this embodiment, the spool 601 is cylindrical, the spool mounting portion 1061 is a circular hole, the radius of the spool 601 is equal to the radius of the spool mounting portion 1061, and the surfaces of the spool 601 and the spool mounting portion 1061 are both smooth surfaces, so as to facilitate sliding. In order to ensure that the filtrate passes through the safety valve when the safety valve is opened, a filtrate passing portion 6011 is provided on the spool 601. In this embodiment, the filtrate passing portion 6011 is formed by providing an annular groove on the spool 601, and the annular groove is coaxial with the spool 601. When the filtrate passing portion 6011 overlaps or partially overlaps with the filtrate outlet, the safety valve is opened, and the filtrate passes through the filtrate passing portion 6011. When the column 601 completely closes the filtrate outlet, the safety valve is closed. The adjustment screw 602 is mounted to the adjustment screw mounting portion 1062, and in particular, the adjustment screw 602 is threadedly coupled to the adjustment screw mounting portion 1062. As an implementation, the open/close state of the safety valve can be changed by rotating the adjusting screw to push the spool 601. This embodiment provides an embodiment of a quick-adjust spool 601 having an adjustment passage 6021 formed through the adjustment screw 602. The adjusting passage 6021 is a through hole that can be connected to an air pump and an air pipe to provide air pressure to push the valve stem 602 by the air pump, so as to change the open/close state of the safety valve. Of course, not only the air pump but also a push pin having a diameter smaller than the adjustment passage 6021 may be used to push the spool 602 to change the open/close state of the safety valve.

The plug 604 is mounted on the plug mounting portion 1063 and mainly provides support for the first spring 603, and another function of the plug 604 is to adjust the sliding termination position of the adjusting valve column 603, so that the filtrate passing portion 6011 and the filtrate outlet 103 exactly coincide with each other. A first spring 603 is mounted between the plug 604 and the spool 601. In the state without external force, the column 601 is overlapped with the filtrate outlet 103 under the elastic force of the first spring 603, and the filtrate outlet 103 is in a closed state. Applying an external force F, for example, air pressure provided by an air pump, the external force F being greater than the restoring force of the first spring 603, the first spring 603 sliding toward the plug, the filtrate passing portion 6011 alternating with the filtrate outlet 103 until completely overlapping, and at this time, the spool 601 cannot slide continuously under the action of the first spring 603 and the plug 604; the external force F is removed, the spool 601 slides to the original position under the restoring force of the first spring 603, the column 601 completely coincides with the filtrate outlet 103, and the filtrate outlet 103 is closed again.

In order to adjust the air pressure between the plug 604 and the spool 601, an air adjusting hole 1064 is provided below the first spring 603 or on the plug 604. In this embodiment, an air adjusting hole 1064 is formed at the transition portion between the plug mounting portion 1063 and the spool mounting portion 1061, and the air adjusting hole 1064 communicates the safety valve mounting hole 106 to the outside of the cup. It is easy to understand that it is also possible to provide an air-adjusting hole in the plug.

It should be noted that although the safety valve mounting hole 106 is described as a through hole in the present embodiment, the plug 604 is mounted at one end, and therefore, the safety valve mounting hole 106 is also configured as a blind hole for the purpose of mounting the safety valve in the present invention. When the safety valve mounting hole 106 is a blind hole, the bottom of the blind hole is a plug.

The inner surface of the cup bottom is provided with a liquid collecting surface 105, the liquid collecting surface 105 is a concave surface, and the filtrate outlet 103 is positioned at the lowest point of the liquid collecting surface 105. A header 105 is provided to facilitate removal of all filtrate in the receiving cup.

In a further embodiment of the method of the present invention,

the cup cover 200 is provided with a cup cover hole 201, a one-way valve is arranged below the cup cover hole 201, and fluid, particularly liquid, can only flow in from the outside of the cup to the inside of the cup but cannot flow out from the inside of the cup to the outside of the cup.

Referring to fig. 2, in this embodiment, the inner space of the cup 100 is divided into two functional areas, i.e., an upper first chamber 101 and a lower second chamber 102. The transition between the first chamber 101 and the second chamber 102 is provided with a step. The sidewall of the cap 200 extends from the rim to the step.

The check valve comprises a check valve core 500 for opening or closing the cup cover hole, a second spring 501 and a check valve seat 400, wherein the check valve core 500 is in sliding fit with the check valve seat 400, and the second spring 501 is arranged between the check valve core and the check valve seat. The one-way valve seat 400 is installed in the first chamber 101 and placed on the step. In this embodiment, the one-way valve seat 400 is embedded in the extending space of the sidewall of the cup cover, the one-way valve seat 400 is seamlessly embedded with the inner surface of the sidewall of the cup cover, and at least one sealing ring is disposed on the attaching surface. When the cup lid is assembled, the one-way valve seat 400 and the side wall of the cup lid are both positioned in the first chamber 101.

The one-way valve core 500 makes the cup lid hole 201 in a normally closed state under the action of the second spring 501. Under the action of external force, for example, at the end of the funnel, when the external force is greater than the supporting force of the second spring 501, the one-way valve core 500 moves downwards, the cup cover hole 201 is opened, and the filtrate enters the receiving cup. When the external force is removed, the one-way valve element 500 closes the cup cover hole 201 again under the restoring force of the second spring 501, and the cup cover hole 201 is closed. The filtrate does not leak out when the receiving cup is shaken or even shaken vigorously.

In a further embodiment of the method of the present invention,

one-way valve seat 400 with from the bottom up installs first grip ring 301, filter 300 and second grip ring 302 in order between the step, first grip ring 301 with the inseparable centre gripping of second grip ring 302 the periphery of filter to make filter 300 keep level and smooth all the time. The filter sheet 300 is preferably filter paper. During filtration, the one-way valve needs to be opened, and moderate air pressure can be applied to the first chamber 101 during the filtration process to increase the filtration speed.

In the case of a filtrate-receiving cup with a filtering function, it is necessary to equalize the gas pressure in the second chamber 102. That is, as the filtrate in the second chamber 102 gradually increases, the air pressure in the second chamber 102 also gradually increases, which is not conducive to filtration. In order to balance the air pressure in the second chamber 102, an air pressure balance groove 104 is arranged on the inner wall of the cup body, the air pressure balance groove 104 is connected with the second chamber 102 and extends to the cup mouth through the inner wall of the first chamber 101, so that the second chamber 102 can be released to the outside of the cup through the air pressure balance groove 104. The air pressure balance groove 104 may be a groove opened in a vertical direction or a groove spirally rising, and preferably, the air pressure balance groove 104 spirally extends from the second chamber 102 to the cup mouth through the inner wall of the first chamber.

When the vortex oscillator needs to be rotated on the filtrate receiving cup, the influence of the air pressure balance groove 104 on the mass distribution of the cup body of the receiving cup needs to be considered, so when the air pressure balance groove 104 is arranged in the vertical direction, a plurality of air pressure balance grooves 104 should be uniformly distributed on the circumference of the inner wall of the cup body. The air pressure balance groove 104 extends from the second chamber 102 to the cup mouth through the inner wall of the first chamber, and a gap may be provided between the connecting threads of the lid and the cup body as an extension of the air pressure balance groove 104.
