[0006] To achieve the above objectives, this utility model provides the following technical solution: a drinking water pH value detection device with a sampling head protection structure, comprising an installation cylinder, a viewing window embedded at one end of the installation cylinder, an inner installation cylinder movably connected inside the installation cylinder, a mounting base fixedly connected to the top end of the inner installation cylinder, a control button movably connected to one end of the mounting base, and a protective structure for protecting the sampling head provided on the outside of the installation cylinder;
[0007] The protective structure includes a second positioning seat, a second positioning seat fixedly connected to the bottom end of the mounting cylinder, a support cylinder fixedly connected to the bottom end of the second positioning seat, a sampling head body fixedly connected to the bottom end of the inner mounting cylinder, a first positioning seat fixedly connected to the top end of the mounting seat, a set of rubber rings fixedly connected to the outside of the second positioning seat and the first positioning seat respectively, a protective cover movably connected to the bottom end of the mounting cylinder, connecting plates fixedly connected to the top ends of both sides of the protective cover, a T-shaped slider fixedly connected to the top end of one side of the connecting plate, and T-shaped grooves opened on both sides of the mounting cylinder.
[0008] As a further technical solution of this utility model, the sampling head body penetrates through the support cylinder and extends to the outside of the support cylinder, and the protective cover is movably connected to the rubber ring.
[0009] As a further technical solution of this utility model, the T-shaped groove is slidably connected to the T-shaped slider, and the center line of the second positioning seat and the center line of the first positioning seat are on the same vertical plane.
[0010] As a further technical solution of this utility model, a fixed cylinder is fixedly connected to the bottom of the inner side of the protective cover, an external threaded cylinder is fixedly connected to the bottom of the protective cover, a threaded sleeve is movably connected to the outside of the external threaded cylinder, a fixed post is fixedly connected to the bottom of the inner side of the threaded sleeve, and an absorbent cotton is fixedly connected to the top of the fixed post.
[0011] As a further technical solution of this utility model, the fixed cylinder is internally connected to the external threaded cylinder, and the center line of the fixed cylinder and the center line of the protective cover are on the same vertical plane.

[0014] As a further technical solution of this utility model, the external threaded ring is threadedly connected to the mounting cylinder, and the center line of the external threaded ring and the center line of the mounting cylinder are on the same vertical plane.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the drinking water pH value detection device with sampling head protection structure not only protects the sampling head and allows for the cleaning of adhering water after the test, but also allows for quick disassembly for internal inspection.
[0016] The device is equipped with a first positioning seat, a connecting plate, a second positioning seat, a protective cover, a sampling head body, a rubber ring, a T-shaped groove, and a T-shaped slider. During testing, the protective cover is first pulled, which drives the T-shaped slider to descend synchronously through the connecting plate. After the T-shaped slider moves to the bottom of the T-shaped groove, the protective cover can be flipped and moved to one end of the mounting cylinder. Then, the protective cover can be pulled upwards and moved to the top of the mounting seat. The protective cover is then pressed to fit over the outside of the first positioning seat for sampling and testing. After the test is completed, the protective cover is pulled again and moved to the bottom of the mounting cylinder and pushed to fit over the outside of the second positioning seat, thus protecting the sampling head body. The rubber rings on the outside of the first and second positioning seats can increase friction and position the protective cover when they are in contact with it, thus protecting the sampling head body after the test.
[0017] By incorporating a protective cover, sampling head body, fixed cylinder, external threaded cylinder, fixed column, threaded sleeve, and absorbent cotton, after the protective cover is fitted onto the outside of the second positioning seat upon completion of the test, the fixed cylinder inside the protective cover will fit onto the outside of the sampling head body. The absorbent cotton inside the fixed cylinder adheres to the bottom of the sampling head body and can quickly absorb the water adhering to the sampling head body during sampling. Afterward, the threaded sleeve can be rotated to remove it from the outside of the external threaded cylinder, and the absorbent cotton can be removed from the inside of the fixed cylinder for cleaning via the fixed column. This allows for the absorption and cleaning of adhering water after the test is completed.
[0018] The device is equipped with a mounting base, a display screen, an inner mounting cylinder, and an external threaded ring. When the internal components need to be inspected, the mounting base can be rotated to rotate the external threaded ring at its bottom. As the external threaded ring rotates, it works in conjunction with the thread at the top of the inner mounting cylinder to remove the inner mounting cylinder from the inside of the cylinder. This allows for the inspection of the detection elements installed inside the inner mounting cylinder. After the inspection is completed, the inner mounting cylinder is reinserted into the cylinder, and the sampling head at its bottom is led out through the support cylinder. The mounting base is then rotated and positioned by the external threaded ring. Once the inner mounting cylinder is in place, the display screen and the viewing window are precisely aligned for observation. This allows for quick disassembly and assembly for the inspection of the internal components. Attached Figure Description

[0026] The protective structure includes a second positioning seat 7, a second positioning seat 7 is fixedly connected to the bottom end of the mounting cylinder 1, a support cylinder 10 is fixedly connected to the bottom end of the second positioning seat 7, a sampling head body 9 is fixedly connected to the bottom end of the mounting inner cylinder 13, a first positioning seat 5 is fixedly connected to the top end of the mounting seat 3, a set of rubber rings 11 are fixedly connected to the outside of the second positioning seat 7 and the first positioning seat 5 respectively, a protective cover 8 is movably connected to the bottom end of the mounting cylinder 1, a connecting plate 6 is fixedly connected to the top end of both sides of the protective cover 8, a T-shaped slider 16 is fixedly connected to the top end of one side of the connecting plate 6, and T-shaped grooves 15 are opened on both sides of the mounting cylinder 1;
[0027] The sampling head body 9 penetrates through the support cylinder 10 and extends to the outside of the support cylinder 10; the protective cover 8 is movably connected to the rubber ring 11.
[0028] T-shaped groove 15 is slidably connected to T-shaped slider 16, and the center line of the second positioning seat 7 is on the same vertical plane as the center line of the first positioning seat 5;
[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during testing, the protective cover 8 is first pulled down, which drives the T-shaped slider 16 to descend synchronously via the connecting plate 6. After the T-shaped slider 16 moves to the bottom of the T-shaped groove 15, the protective cover 8 can be flipped and moved to one end of the mounting cylinder 1. Then, the protective cover 8 can be pulled up and moved to the top of the mounting seat 3. The protective cover 8 is then pressed to fit over the outside of the first positioning seat 5 for sampling and testing. After the test is completed, the protective cover 8 is pulled down and moved to the bottom of the mounting cylinder 1 and pushed to fit over the outside of the second positioning seat 7 to protect the sampling head body 9. The rubber rings 11 on the outside of the first positioning seat 5 and the second positioning seat 7 can increase the friction and position the protective cover 8 when it is in contact with the protective cover 8, thus protecting the sampling head body 9 after the test.
[0030] A fixed cylinder 17 is fixedly connected to the bottom of the inside of the protective cover 8. An external threaded cylinder 18 is fixedly connected to the bottom of the protective cover 8. A threaded sleeve 20 is movably connected to the outside of the external threaded cylinder 18. A fixed post 19 is fixedly connected to the bottom of the inside of the threaded sleeve 20. A water-absorbing cotton 21 is fixedly connected to the top of the fixed post 19.
[0031] The fixed cylinder 17 is internally connected to the external threaded cylinder 18, and the center line of the fixed cylinder 17 and the center line of the protective cover 8 are on the same vertical plane.
[0032] The absorbent cotton 21 is movably connected to the sampling head body 9, and the fixed column 19 is movably connected to the external threaded cylinder 18;
[0033] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, after the test is completed and the protective cover 8 is fitted onto the outside of the second positioning seat 7, the fixing cylinder 17 inside the protective cover 8 will be fitted onto the outside of the sampling head body 9. The water-absorbing cotton 21 inside the fixing cylinder 17 adheres to the bottom of the sampling head body 9 and can quickly absorb the water attached to the sampling head body 9 during sampling. Then, the threaded sleeve 20 can be rotated to remove it from the outside of the external threaded cylinder 18, and the water-absorbing cotton 21 can be removed from the inside of the fixing cylinder 17 for cleaning through the fixing post 19. This allows the attached water to be absorbed and cleaned after the test is completed.

[0036] Specifically, such as Figure 1 and Figure 2As shown, when it is necessary to inspect the internal components of the device, the mounting base 3 can be rotated to drive the external threaded ring 14 at its bottom to rotate. While the external threaded ring 14 rotates, it cooperates with the thread set at the top of the mounting cylinder 1 to remove the inner mounting cylinder 13 from the inside of the mounting cylinder 1, so as to facilitate the inspection of the detection element installed inside the inner mounting cylinder 13. After the inspection is completed, the inner mounting cylinder 13 is inserted into the inside of the mounting cylinder 1, and the sampling head body 9 at its bottom is pushed out through the support cylinder 10. Then, the mounting base 3 is rotated to position the mounting base 3 through the external threaded ring 14. After the inner mounting cylinder 13 is rotated into place, the position of the display screen 12 and the viewing window 2 are precisely aligned for observation, realizing quick disassembly and assembly for the inspection of internal components.
[0037] Working Principle: In use, during testing, the protective cover 8 is first pulled down, causing the T-shaped slider 16 to descend synchronously via the connecting plate 6. After the T-shaped slider 16 moves to the bottom of the T-shaped groove 15, the protective cover 8 can be flipped and moved to one end of the mounting cylinder 1. Then, the protective cover 8 can be pulled upwards and moved to the top of the mounting base 3. The protective cover 8 is then pressed to fit over the first positioning seat 5 for sampling and testing. After testing, the protective cover 8 is pulled again and moved to the bottom of the mounting cylinder 1, then pushed to fit over the second positioning seat 7, protecting the sampling head body 9. The rubber rings 11 on the outside of the first and second positioning seats 5 increase friction and position the protective cover 8 when it is in contact with it. After testing, when the protective cover 8 is fitted over the second positioning seat 7, the fixing cylinder 17 inside the protective cover 8 will fit over the sampling head body 9. The suction inside the fixing cylinder 17... The water-absorbing cotton 21, attached to the bottom of the sampling head body 9, can quickly absorb the water adhering to the sampling head body 9 during sampling. Then, the threaded sleeve 20 can be rotated to remove it from the outside of the external threaded cylinder 18, and the water-absorbing cotton 21 can be removed from the inside of the fixed cylinder 17 for cleaning via the fixed column 19. When it is necessary to inspect the internal components of the device, the mounting base 3 can be rotated to drive the external threaded ring 14 at its bottom to rotate. As the external threaded ring 14 rotates, it works with the thread set at the top of the mounting cylinder 1 to remove the inner mounting cylinder 13 from the inside of the mounting cylinder 1, so as to facilitate the inspection of the detection element installed inside the inner mounting cylinder 13. After the inspection is completed, the inner mounting cylinder 13 is inserted into the inside of the mounting cylinder 1, and the sampling head body 9 at its bottom is led out through the support cylinder 10. Then, the mounting base 3 is rotated and positioned by the external threaded ring 14. After the inner mounting cylinder 13 is rotated into place, the display screen 12 and the viewing window 2 are precisely aligned for observation.
