Description

Technical Field

[0001] This utility model relates to the field of drinking water treatment technology, specifically to a portable water quality testing device. Background Technology

[0002] Drinking water is an indispensable part of human life and is crucial to health. It must meet certain hygiene standards to ensure it is free of harmful substances and microorganisms. The main sources of drinking water include groundwater, such as well water and spring water, which is generally considered relatively safe because it has undergone natural filtration; surface water, such as rivers, lakes, and reservoirs, which requires strict treatment to remove pollutants; rainwater, which can be treated appropriately for drinking; and seawater desalination, which uses technology to remove salt from seawater to make it suitable for drinking. Drinking water treatment is an important process aimed at ensuring that water sources are safe, clean, and meet drinking standards. Countries and regions have strict standards for the safety of drinking water, and when new water sources are found, they are tested to ensure they are free of toxic substances.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] 1. Water quality testing equipment is often carried to remote mountainous areas for water quality testing. To keep the equipment as simple as possible when carrying it, most water quality testing equipment is currently stored in a box, which is quite large and takes up a lot of space when carried.

[0005] 2. The water quality testing equipment and the probe are connected by a data cable. The water quality testing probe needs to be inserted into the bottom of the water for testing. In order to test deeper water sources, the data cable is relatively long. The process of storing the data cable is quite troublesome. Each time the data cable is stored, it needs to be unplugged and stored separately. Repeated plugging and unplugging of the data cable will cause the interface to loosen. Utility Model Content

[0006] The purpose of this utility model is to provide a portable water quality testing device to solve the problems mentioned in the background art, such as the inconvenience of carrying the testing device, its large footprint, and the difficulty in storing the data cable used to connect the probe and the testing instrument. To achieve the above objective, this utility model provides the following technical solution: a portable water quality testing device, including a handheld testing instrument, a lanyard inserted into the top of the handheld testing instrument, a data cable inserted into the bottom of the handheld testing instrument, a cable storage mechanism installed on the side of the handheld testing instrument, and a probe storage mechanism installed on the back of the handheld testing instrument, with a testing head sleeved inside the probe storage mechanism.

[0007] The wire storage mechanism includes a large gear, a small gear meshing below the large gear, a wire spool mounted on one side of the small gear, and a motor mounted on one side of the large gear.

[0008] The probe storage mechanism includes a protective sleeve, a cover plate rotatably connected to the top of the protective sleeve, a limiting hole on the upper surface of the cover plate, a limiting rod welded to the top of the protective sleeve, a lead screw threaded to the top of the limiting rod, a steel ball welded to one end of the lead screw, and an annular baffle plate at the bottom of the inner wall of the protective sleeve.

[0009] More preferably, the large gear and the small gear are configured with a meshing transmission structure.

[0010] In a further preferred embodiment, the coil is rotated by a motor, and the data cable is wound around the surface of the coil.

[0011] More preferably, the top of the detection head is in close contact with the lower surface of the cover plate, and the bottom of the detection head is in close contact with the upper surface of the annular baffle.

[0012] More preferably, the protective sleeve is bonded to the back of the handheld detector by adhesive bonding, and the side of the protective sleeve is designed as an open structure.

[0013] More preferably, the steel ball and the limiting hole are connected by an insertion method.

[0014] More preferably, the cover plate is circular, and the lower surface of the cover plate is provided with a soft silicone layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the probe storage mechanism is attached to the back of the handheld detector. The upper and lower ends of the probe head are attached to the cover plate and the annular baffle, respectively. The rotation of the screw drives the steel ball to move up and down, limiting the cover plate and preventing the probe head from swinging back and forth inside the protective sleeve. The side opening of the protective sleeve facilitates the passage of the data cable, which is stored on the side of the handheld detector. When carrying it, simply lift the lanyard, which is convenient for carrying accessories and takes up less space.

[0017] In this invention, a motor drives a large gear to rotate, which in turn drives a small gear to rotate, increasing the transmission ratio and improving the torque output of the mechanical device. This allows for quick data cable storage. As the reel rotates, the data cable, which is attached to the surface of the reel, begins to wind and store itself. The reel supports and limits the movement of the data cable, preventing it from falling off. The data cable can be stored directly without repeated plugging and unplugging, preventing the interface from becoming loose. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a portable water quality testing device, including a handheld tester 1, a hanging rope 2 inserted into the top of the handheld tester 1, a data cable 3 inserted into the bottom of the handheld tester 1, a cable storage mechanism 4 installed on the side of the handheld tester 1, and a probe storage mechanism 5 installed on the back of the handheld tester 1, with a probe sleeved inside the probe storage mechanism 5.

[0026] The cable storage mechanism 4 includes a large gear 401, a small gear 402 meshing below the large gear 401, a cable reel 403 mounted on one side of the small gear 402, and a motor 404 mounted on one side of the large gear 401.

[0027] The probe storage mechanism 5 includes a protective sleeve 501, a cover plate 502 rotatably connected to the top of the protective sleeve 501, a limiting hole 503 on the upper surface of the cover plate 502, a limiting rod 504 welded to the top of the protective sleeve 501, a lead screw 505 threadedly connected to the top of the limiting rod 504, a steel ball 506 welded to one end of the lead screw 505, and an annular baffle 507 provided at the bottom of the inner wall of the protective sleeve 501.

[0028] In this embodiment, as Figure 1 and Figure 3 As shown, the large gear 401 and the small gear 402 are designed with a meshing transmission structure. It should be noted that the large gear 401 drives the small gear 402 to rotate, which increases the transmission ratio and improves the torque output of the mechanical device, allowing the data cable 3 to be quickly stored.

[0029] In this embodiment, as Figure 1 and Figure 3 As shown, the coil 403 rotates via the motor 404, and the data cable 3 is wound around the surface of the coil 403. It should be noted that when the coil 403 rotates, the data cable 3, which is attached to the surface of the coil 403, will begin to wind and collect itself. The coil 403 provides support and limits the movement path of the data cable 3, preventing the data cable 3 from falling off.

[0030] In this embodiment, as Figure 4 As shown, the top of the detection head 6 is tightly fitted with the lower surface of the cover plate 502, and the bottom of the detection head 6 is tightly fitted with the upper surface of the annular baffle 507. It should be noted that the upper and lower ends of the detection head 6 are fitted with the cover plate 502 and the annular baffle 507 respectively to prevent the detection head 6 from shaking back and forth inside the protective sleeve 501.

[0031] In this embodiment, as Figure 2 and Figure 4 As shown, the protective sleeve 501 is glued to the back of the handheld detector 1, and the side of the protective sleeve 501 is designed with an opening. It should be noted that the probe storage mechanism 5 is attached to the back of the handheld detector 1 as a whole. The side opening of the protective sleeve 501 facilitates the passage of the data cable 3. The data cable 3 is stored on the side of the handheld detector 1. When carrying it, you only need to lift the lanyard 2. There is no need to carry other unrelated products, and the space occupied is smaller.

[0032] In this embodiment, as Figure 5 As shown, the steel ball 506 and the limiting hole 503 are connected by an insertion method. It should be noted that the rotation of the lead screw 505 drives the steel ball 506 to move up and down. When the steel ball 506 is disengaged from the limiting hole 503, the cover plate 502 can be rotated open to facilitate the removal of the probe. When the cover plate 502 rotates back and the steel ball 506 is inserted into the limiting hole 503, it plays a limiting role on the cover plate 502 to prevent the cover plate 502 from rotating back and forth.

[0033] In this embodiment, as Figure 4 As shown, the cover plate 502 is circular, and a soft silicone layer is provided on the lower surface of the cover plate 502. It should be noted that the cover plate 502 is circular, and the area of ​​the cover plate 502 is the same as the area of ​​the protective sleeve 501. The soft silicone layer on the lower surface of the cover plate 502 can protect the top of the probe.

[0034] The method of use and advantages of this utility model: The working process of this portable water quality testing device is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, retract the tested probe and data cable 3. Start motor 404. Motor 404 drives the large gear 401 to rotate, and the small gear 402, which meshes with the large gear 401, can start rotating. The small gear 402 drives the coil 403 to rotate rapidly. When the coil 403 rotates, it drives the data cable 3 to wind around the surface of the coil 403 one circle at a time. Set the operating time of motor 404. When the data cable 3 is completely retracted into the surface of the coil 403, turn off motor 404. Motor 404 can rotate forward and reverse. When motor 404 rotates in reverse, the data cable 3 can start to unwind from the coil 403. Okay, the probe is also retracted. The lead screw 505 reverses, and the steel ball 506 disengages from the limiting hole 503. The cover plate 502 is rotated 180°. The detection head 6 is moved along the top of the protective sleeve 501. The data cable 3 is inserted into the opening on the side of the protective sleeve 501. The detection head 6 is slid down along the protective sleeve 501 until the bottom of the detection head 6 is in contact with the annular baffle 507. The cover plate 502 is rotated again and reset. The lead screw 505 rotates forward, causing the steel ball 506 to move down and insert into the limiting hole 503. The steel ball 506 presses down and fixes the cover plate 502, further securing the entire detection head 6. All accessories can be carried by lifting the hanging rope 2.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
