Abstract

The utility model relates to a water quality analyzer which can be used for cleaning a sample cell automatically. The water quality analyzer comprises a flow path switching valve, a liquid feeding device, a sample cell and a cleaning solution container, wherein the flow path switching valve comprises a common port and a plurality of ports which can be communicated with the common port by virtue of switching; the liquid feeding device is communicated with the common port of the flow path switching valve; the sample cell is connected to one of the plurality of ports of the flow path switching valve; the cleaning solution container is communicated with another port of the plurality of ports of the flow path switching valve; by virtue of the switching of the flow path switching valve, the liquid feeding device can be used for intaking the cleaning solution and injecting into the sample cell to clean the sample cell.

Description

Water Test Kits

Technical field

The utility model relates to a kind of Water Test Kits, particularly relates to a kind ofly can carrying out the Water Test Kits automatically cleaning to sample cell.

Background technology

In analytical instrument of water quality, often can use sample cell and deposit the water sample that needs test, after long-time use, sample cell may occur dirty, at this moment just need to clean sample cell.Product in the past much all needs sample cell to take apart, then injects cleaning fluid and cleans, and this work is both time-consuming, requires great effort again, and because some cleaning fluid itself has danger, when operating, sometimes also can damage the person.

Utility model content

In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of Water Test Kits, comprise flow channel switching valve, a plurality of ports that flow channel switching valve has a public port and can be communicated with public port by switching; Liquid feeding device, liquid feeding device is communicated to the public port of flow channel switching valve; Sample cell, sample cell is communicated to a port in a plurality of ports of flow channel switching valve; And soda liquor container, soda liquor container is communicated to another port in a plurality of ports of flow channel switching valve; Wherein, flow channel switching valve can switch between suction condition and inject state, and under suction condition, public port is communicated with another port in a plurality of ports, and liquid feeding device sucks cleaning fluid from soda liquor container; Under inject state, public port is communicated with a port in a plurality of ports, and liquid feeding device is injected into the cleaning fluid of suction in sample cell and cleans.

Further, according in Water Test Kits of the present utility model, other ports except described and described another port in a plurality of ports are also connected with respectively analyrical reagent container; And soda liquor container is connected to by off-line transfer valve on another port in a plurality of ports of flow channel switching valve.

Water Test Kits according to another embodiment of the utility model, comprises flow channel switching valve, a plurality of ports that flow channel switching valve has a public port and can be communicated with public port by switching; Liquid feeding device, liquid feeding device is communicated to the public port of flow channel switching valve; Sample cell, sample cell is communicated to a port in a plurality of ports of flow channel switching valve; Analyrical reagent container, and soda liquor container, analyrical reagent container and soda liquor container are communicated to another port in a plurality of ports of flow channel switching valve by off-line transfer valve; Wherein, flow channel switching valve can switch between suction condition and inject state, and under suction condition, public port is communicated with another port in a plurality of ports, and off-line transfer valve switches to the state that is communicated with soda liquor container, and liquid feeding device sucks cleaning fluid from soda liquor container; Under inject state, public port is communicated with a port in a plurality of ports, and liquid feeding device is injected into the cleaning fluid of suction in sample cell and cleans.

Adopt Water Test Kits of the present utility model, when sample cell is cleaned, cleaning fluid can be added to sample cell automatically, and not need sample cell to take apart, thereby realized the function of automatic cleaning.

Accompanying drawing explanation

Fig. 1 is according to the schematic diagram of the structure of Water Test Kits of the present utility model.

Embodiment

As shown in Figure 1, according to the Water Test Kits of an embodiment of the present utility model, comprise soda liquor container 1, off-line switching solenoid valve 2, eight logical valves 3, needle tubing 4, sample cell 5, in soda liquor container 1, deposit and clean sample cell 5 cleaning fluid used, eight logical valves 3 have a public port and port one-8, by the switching of valve, port one-8 can be communicated with respectively at public port, needle tubing 4 is connected on this public port, soda liquor container 1 is connected on the port one of eight logical valves 3, and sample cell 5 is connected on the port 7 of eight logical valves 3.When needs clean sample cell, eight logical valves 3 rotate, make port one and public port be the state being communicated with, at this moment, needle tubing 4 is drawn cleaning fluid from soda liquor container 1, and then, eight logical valves 3 turn to the state that public port is communicated with port 7, needle tubing 4 is injected into the cleaning fluid sucking in sample cell 5 again, thereby completes the cleaning of sample cell.

Although soda liquor container 1 has been shown in Fig. 1, be connected on the port one of eight logical valves 3 by off-line switching solenoid valve 2, because eight logical valves 3 itself can switch, so off-line switching solenoid valve 2 is not necessary parts.Meanwhile, the ports that are connected to eight logical valves that are also appreciated that soda liquor container and sample cell are not limited to the situation of No. 1 shown in Fig. 1 and No. 7, as long as can cleaning fluid be injected in sample cell by the switching of valve.

Further, as shown in Figure 1, other ports of eight logical valves 3 are also connected with different reagent, and as mentioned above, soda liquor container 1 also can be connected to other above-mentioned ports, now, just must connect by off-line transfer valve.Cleaning process is similar, by the switching of eight logical valves 3 and off-line transfer valve 2, utilizes needle tubing 4 to suck cleaning fluid, and cleaning fluid is injected in sample cell 5 again.

According to Water Test Kits of the present utility model, when sample cell is cleaned, do not need sample cell just to pull down and can complete automatic cleaning, thereby reduced the needs to manpower, and the personnel's that may occur, cause due to cleaning liquid harm.

Although the utility model discloses as above with preferred embodiment; but be not for limiting the utility model; any person of ordinary skill in the field; within not departing from spirit and scope of the present utility model; can do a little change and retouching, therefore protection domain of the present utility model is with being as the criterion that claim was defined.
