[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figure 1-3 This utility model provides a technical solution: a protective shell for a water quality tester with a waterproof structure, comprising: a lower shell 1, an upper cover 2 at the upper end of the lower shell 1, a handle 3 fixedly connected to the upper end of the upper cover 2, a test interface 4 at the lower end of the left side of the lower shell 1, a flip-type waterproof cover 5 correspondingly provided on the test interface 4, the flip-type waterproof cover 5 being rotatably connected to the lower shell 1 via a spring hinge, and a locking component 6 located on the lower shell 1, the locking component 6 being used to seal and fix the upper cover 2 to the lower shell 1.

[0025] In this implementation, the water quality analyzer main unit is placed inside the lower shell 1, ensuring that the analyzer interface corresponds to the detection interface 4 of the lower shell 1. The upper cover 2 is then closed, allowing the stepped sealing protrusion 7 to be embedded inside the upper cover 2, and the sealing gasket 11 to initially fit. The four sets of wing screws 63 are then tightened in sequence, and the upper cover 2 is pressed down by the fixing block 62 until the sealing gasket 11 is compressed by 2mm. The tightness of the wing screws 63 can be used to check the tightness. At this point, the lower shell 1 and the upper cover 2 form a completely sealed cavity, preventing the intrusion of external liquids. When the detection interface 4 needs to be used, the flip-type waterproof cover 5 is opened upwards with one hand. The spring hinge automatically opens the flip-type waterproof cover 5 at a 90° angle, allowing the detection interface 4 to be connected. After the operation is complete, the flip-type waterproof cover 5 can be closed.

[0026] Example 2:

[0027] Please see Figure 1-3As shown, based on Embodiment 1, this utility model provides a technical solution: four sets of locking components 6 are symmetrically distributed around the lower shell 1. The locking components 6 include a threaded seat 61, and a fixing block 62 is provided at the upper end of the threaded seat 61. The fixing block 62 is fixedly connected to the upper cover 2. A through hole is opened on the fixing block 62 corresponding to the position of the threaded seat 61, and a wing screw 63 is inserted into the through hole. The lower end of the wing screw 63 passes through the fixing block 62 and is threadedly connected to the upper end of the threaded seat 61. The upper end of the lower shell 1 and the lower end of the upper cover 2 are connected. The mating edge is provided with a stepped sealing protrusion 7. The lower end of the stepped sealing protrusion 7 is fixedly connected to the upper end of the lower shell 1. Moisture-proof adsorption sheets are fixedly connected to the four sides of the inner wall of the lower shell 1. An O-ring seal 8 is fixedly connected to the inner wall of the detection interface 4. A one-way drain valve 9 is connected to the front side of the lower end of the lower shell 1. A column 10 is fixedly connected to the four sides of the lower end of the lower shell 1. A pad is fixedly connected to the lower end of the column 10. A sealing gasket 11 is sleeved on the surface of the stepped sealing protrusion 7. The lower end of the sealing gasket 11 is fixedly connected to the upper end of the lower shell 1.

[0028] In this embodiment: if the lower shell 1 is sprayed with rainwater or splashed with water accidentally, observe whether there is water accumulation at the bottom of the lower shell 1. If there is water accumulation, press the valve cap of the one-way drain valve 9, and the water will be discharged in a directional manner through the valve core. After releasing, the valve core will automatically reset and seal. After long-term use, the upper cover can be opened periodically to replace the inner moisture-proof absorbent sheet to ensure that the lower shell 1 is dry. After the test is completed, loosen the four sets of butterfly screws 63 in the reverse direction, lift the upper cover 2 and take out the water quality tester main unit. When the lower shell 1 is empty, keep the flip-type waterproof cover 5 closed and carry it through the handle 3. The column 10 and the pad can ensure that the lower shell 1 is suspended when placed to avoid ground moisture erosion.

[0029] The working principle of the waterproof protective shell for a water quality analyzer provided by this utility model is as follows:

[0030] Implementation steps for the first innovation point:

[0031] Step 1: Place the water quality tester main unit into the lower shell 1, ensuring that the tester interface corresponds to the test interface 4 of the lower shell 1. Cover the upper cover 2, so that the stepped sealing protrusion 7 is embedded in the upper cover 2 and the sealing gasket 11 is initially attached. Tighten the four sets of wing screws 63 in sequence, and press the upper cover 2 down through the fixing block 62 until the sealing gasket 11 is compressed by 2mm. The tightness of the wing screws 63 can be used to check the feedback.

[0032] Step 2: At this point, the lower shell 1 and the upper cover 2 form a completely sealed cavity, preventing external liquid from entering. When the detection interface 4 is needed, pry open the flip-type waterproof cover 5 with one hand. The spring hinge will automatically open the flip-type waterproof cover 5 at a 90° angle. After connecting the detection cable or charger to the detection interface 4, the flip-type waterproof cover 5 can be closed after the operation is completed.

[0033] Implementation steps for the second innovation point:

[0034] Step 1: If the lower shell 1 is sprayed with rainwater or splashed with water accidentally, check whether there is water accumulation at the bottom of the lower shell 1. If there is water accumulation, press the valve cap of the one-way drain valve 9. The water will be discharged in a directional manner through the valve core. After releasing, the valve core will automatically reset and seal. After long-term use, the upper cover can be opened periodically to replace the inner moisture-proof absorbent sheet to ensure that the lower shell 1 is dry.

[0035] Step 2: After the test is completed, loosen the four sets of wing screws 63 in the reverse direction, lift the top cover 2 and take out the water quality tester main unit. When the lower shell 1 is empty, keep the flip-type waterproof cover 5 closed. It can be carried by the handle 3. The column 10 and the pad can ensure that the lower shell 1 is suspended when placed to avoid ground moisture corrosion.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
