Technical Field

[0001] The utility model relates to the field of water sample detection equipment, in particular to a multifunctional water quality extraction filter. Background Art

[0002] A water quality filter is a special device for filtering collected water samples on site. At present, similar products on the market have defects such as a single filtration function and incomplete filtration, and cannot filter quantitatively and regularly. In addition, the filtration structure of the water quality filter uses filter membrane interception as the main filtration means, wherein the filter membrane needs to be replaced. However, the reality is that the filter membrane enters the container in a filling manner. If you want to pick up the filter membrane that enriches water after use, you need tweezers and other sharp instruments to assist, and even with the above instruments, the picking process is relatively complicated, and considering that tweezers and other sharp instruments are not instrument-related structures and are not carried with you, therefore, based on the above description, there is a need for a multifunctional water quality filter that can be used for filtration enrichment of environmental DNA and collection and retention of water-soluble heavy metal water samples, to achieve large-capacity in situ enrichment of environmental DNA samples, and on-site pre-treatment of water-soluble heavy metal sampling, and with the function of convenient and easy replacement of filter membranes.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0028] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] In this embodiment, a multifunctional water quality filter is proposed. Figure 1-Figure 6 The multifunctional water quality extraction filter comprises a main unit 1, two pump sets in the main unit 1, and batteries for supplying power to the two pump sets.

[0031] To further explain, the pump assembly is a diaphragm pump, and the battery has the ability to store electricity, so that the host 1 can be used without mains electricity.

[0032] See also Figure 1 , Figure 2 And Figure 3 For reference, two cup holders 2 are respectively provided on both sides of the main unit 1, and an enrichment cup 3 is placed in each cup holder 2. The enrichment cup 3 is matched with a filter cup 7 provided above the main unit 1. Figure 3 The filter membrane is filled in the direction of the arrow.

[0033] Further explanation: the enrichment cup 3 is covered with an enrichment cup cover 4 at the mouth of the enrichment cup 3, and the enrichment cup cover 4 is equipped with two hoses extending into the enrichment cup 3, such as Figure 1 and Figure 2 As shown, the two hoses are respectively a first hose 5 and a second hose 6, wherein the first hose 5 is connected to the discharge port of the filter cup 7, and the second hose 6 is connected to the corresponding diaphragm pump. In this way, after the diaphragm pump is started, there is a negative pressure in the enrichment cup 3, and the water filtered by the filter membrane in the filter cup 7 will enter the enrichment cup 3.

[0034] The multifunctional water quality extraction filter proposed in this embodiment has other functions. For details, please refer to Figure 3-Figure 6A filter cup cover 8 is provided at the mouth of the filter cup 7, and a conduit 14 extending outward is provided at the axis of the filter cup cover 8. The conduit 14 is used to connect a water inlet hose. It should be noted that the other end of the water inlet hose is placed in the water sample to be collected.

[0035] To further explain, the outer periphery of the conduit 14 has a thread 17, and the conduit 14 is also connected to a cone head 15, so that when the filter cup cover 8 is inverted and close to the filter cup 7, the cone head 15 will penetrate into the filter membrane, and based on the thread 17 enveloping the edge of the punctured opening of the filter membrane, the filter membrane can be taken out of the filter cup 7.

[0036] To further explain, at the bottom of the filter cup 7 there is a row pipe which coincides with the axis of the filter cup cover 8, and the diameter of the row pipe is larger than the diameter of the cone head 15. Thus, when the filter cup cover 8 is turned upside down and close to the filter cup 7, the cone head 15 will enter the row pipe after piercing the filter membrane, and during the entry, the thread 17 will embrace the edge of the pierced hole of the filter membrane.

[0037] As described above, the function other than the catheter 14 is to connect the water inlet hose, but the end of the catheter 14 in this embodiment is connected to the cone head 15, and the cone head 15 may pierce the water inlet hose. For this reason, three through grooves 16 connected to the catheter 14 are arrayed at the cone head 15, and a sleeve 9 is also provided. The sleeve 9 is screwed on the catheter 14, and multiple catheters 14 to the sleeve 9 are exposed to the outside. In this way, the water inlet hose is trapped on the sleeve 9, and the water sucked by the pump will enter the catheter 14 through the through groove 16.

[0038] Further explanation, the sleeve 9 as described above replaces the conduit 14 to be connected to the water inlet hose. In addition, the sleeve 9 can be submerged in the sharp part of the cone head 15 when the sleeve 9 is threadedly matched with the thread 17, so as to provide necessary protection for personnel when the sleeve 9 is not connected to the water inlet hose.

[0039] The multifunctional water quality filter proposed in this embodiment also has the following contents that need to be explained:

[0040] ① A display 10 is provided in front of the host 1, and the display 10 can be controlled by touch. The display 10 is also equipped with a PCB for controlling the pumping time and pumping flow rate of the pump group.

[0041] Further explanation: the control chip equipped with the PCB can also arbitrarily control the start or stop of the two sets of diaphragm pumps. In this way, according to actual needs, either one set of diaphragm pumps is started to filter the corresponding water sample, or the two sets of diaphragm pumps are started at the same time to filter the corresponding water samples respectively.

[0042] ② On one side of the host 1, there is a switch 11 for controlling the entire host 1 to be turned on or off. Adjacent to the switch 11 is a power connection part 12, which can charge the battery. On the other side of the host 1, there is a drain outlet 13 connected to the discharge outlet of the pump group, and the drain outlet 13 can discharge the overflowed liquid in the enrichment cup 3.

[0043] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
