Description

Technical Field

[0001] The utility model belongs to the technical field of nitrite sensors, and particularly relates to a self-cleaning nitrite sensor. Background Technique

[0002] Nitrite is a general term for a class of inorganic compounds, which widely exist in various water bodies and pickled products in nature and industrial production, such as groundwater, surface water, aquaculture ponds, drinking water, seawater, industrial wastewater, and sausages, pickles, etc. In industrial production, it is often used as a food additive to improve the taste, color, and extend the shelf life of food. Nitrite is a toxic substance and is harmful to humans and aquatic organisms. A nitrite sensor is a sensor for measuring the concentration of its aqueous solution. With the development of the times, the nitrite sensor has gradually evolved from a huge volume to a portable one. This portable nitrite sensor is usually cylindrical, and there is a detection groove on one side of the cylinder. When the nitrite sensor is placed in water, the emitted ultraviolet light and the received ultraviolet light in the detection groove cooperate with each other to detect the data of the components in the flowing water, achieving the effect of detecting nitrite.

[0003] However, there are some problems in the prior art: After the portable outdoor nitrite sensor on the market is used once, impurities are easily attached to the surfaces of the two light holes in the detection groove. Therefore, after each use, the staff needs to flush the inside of the light holes with pure water and wipe them with a paper towel. However, the capacity of the detection groove is small, which leads to the fact that after the staff uses the nitrite sensor each time, it takes some time to clean, which is time-consuming and laborious. Moreover, when manually cleaning the detection groove, the line of sight is easily limited, resulting in the cleaning effect not being guaranteed to be very good, and there are certain limitations. Therefore, we propose a self-cleaning nitrite sensor. Content of the Utility Model

Specific embodiments

[0027] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and detailed as follows in conjunction with the drawings.

[0028] As Figures 1 to 7 shown, a self-cleaning nitrite sensor provided by an embodiment of the present utility model includes: a sensor body 1, a data transmission head 2 is arranged at the upper end of the sensor body 1, and a sampling cavity 6 is opened outside the sensor body 1; a flushing assembly 4, there are two groups of flushing assemblies 4, the two groups of flushing assemblies 4 are symmetrically arranged up and down, and both groups of flushing assemblies 4 are arranged close to the sampling cavity 6, and a sealing shell 3 is fixedly installed outside the two groups of flushing assemblies 4, and the sealing shell 3 is slidably connected with the sensor body 1;

[0029] As Figures 1 to 7 , through the design that a sealing shell 3 is fixedly installed outside the two groups of flushing assemblies 4, the positions of the two groups of flushing assemblies 4 can be changed. When the sensor body 1 is put into water to detect nitrite, the sealing shell 3 can drive the two groups of flushing assemblies 4 to flip and move to the position opposite to the sampling cavity 6, so as to avoid the sealing shell 3 from affecting the water flow through the inside of the sampling cavity 6.

[0030] The wiping assembly 10 is disposed between two flushing assemblies 4. The ends of the wiping assembly 10 are in contact with both ends inside the sampling chamber 6, and the wiping assembly 10 is movably connected to the sealing housing 3.

[0031] As Figures 1 to 7 shown, through the design that both ends of the wiping assembly 10 are in contact with both ends inside the sampling chamber 6, the wiping assembly 10 can work inside the sealing housing 3, thereby cleaning the impurities attached inside the sampling chamber 6. Therefore, the wiping assembly 10 cooperating with the flushing assembly 4 can better clean the inside of the sampling chamber 6.

[0032] Furthermore, the flushing assembly 4 includes a water storage tank 401 and a mounting housing 404. One side of the mounting housing 404 is threadedly connected to the water storage tank 401, and a filter hole is provided inside the mounting housing 404. A filter plate 405 is disposed inside the filter hole. A water pump 403 is fixedly mounted on the other side of the mounting housing 404. The water suction end of the water pump 403 is communicated with a water suction pipe 406. The water suction pipe 406 penetrates through the filter plate 405 to the inside of the water storage tank 401. One end of the water pump 403 is movably connected to an electric spray head 402, and the electric spray head 402 is communicated with the inside of the water pump 403 through a pipeline; One end of the water pump 403 is threadedly connected to an inclined plate 15. One end of the inclined plate 15 is rotatably connected to a bearing plate 9. The bearing plate 9 is rotatably connected to the electric spray head 402, and the electric spray head 402 is inclined through the inclined plate 15. The water spraying end of the electric spray head 402 is correspondingly arranged with one end inside the sampling chamber 6; The bearing plate 9 is rotatably arranged on the surface of the inclined plate 15 through the wiping assembly 10;

[0033] As Figure 3 and Figure 7 shown, through the design that the electric spray head 402 is communicated with the inside of the water pump 403 through a pipeline, when the water pump 403 pumps out pure water or alcohol inside the water storage tank 401, the electric spray head 402 can directly spray the water source into the sampling chamber 6, and the electric spray head 402 is inclined through the inclined plate 15. Therefore, the water source can be more fully scattered inside the sampling chamber 6, thereby further improving the cleaning effect inside the sampling chamber 6;

[0034] It should be noted that there are two groups of the above-mentioned water storage tanks 401, and pure water and alcohol can be respectively used inside the two groups of water storage tanks 401. Pure water is sprayed for the first time and alcohol is sprayed for the second time. Moreover, the pure water or alcohol sprayed by the two electric spray heads 402 is atomized. Thus, the two electric spray heads 402 can fully wet the inside of the sampling chamber 6. And the above-mentioned electric spray heads 402 are set to be inclined, which can better concentrate the excess water to one area, while a relatively small amount of atomized water can be concentrated at the opposite position. Therefore, the two electric spray heads 402 cooperate with each other to spray the atomized pure water and alcohol onto the inside of the sampling chamber 6 comprehensively.

[0035] Furthermore, the sealing housing 3 is composed of a protective housing 302 and two sets of guiding and sliding housings 301. Installation holes are formed at both ends of the protective housing 302. The installation housing 404 is fixedly installed inside the installation holes. A fitting groove is formed on one side of the protective housing 302. Two sets of flushing assemblies 4 are correspondingly arranged inside the fitting groove. Two sets of guiding and sliding housings 301 are symmetrically and fixedly installed inside the fitting groove. Two sets of hollow slide rails 5 are fixedly sleeved outside the sensor body 1. Both sets of guiding and sliding housings 301 are slidably connected to the outer circumference of the two sets of hollow slide rails 5. Sealing plugs 303 are fixedly installed inside both sets of guiding and sliding housings 301. A threaded housing 12 is fixedly installed on the outer circumference at the connection between the water storage tank 401 and the installation housing 404. A screw 11 is threadedly connected inside the threaded housing 12. The threaded housing 12 is detachably connected to the hollow slide rail 5 through the screw 11.

[0036] As Figures 1 to 4 shown, through the design that sealing plugs 303 are fixedly installed inside both sets of guiding and sliding housings 301, the two sets of guiding and sliding housings 301 cooperate with the sealing plugs 303 to better seal the protective housing 302, thereby preventing water from entering the inside of the protective housing 302 when the sensor body 1 penetrates into the water, which may affect the normal use of the flushing assembly 4 and the wiping assembly 10.

[0037] It should be noted that after the guiding and sliding housing 301 slides around the sensor body 1 for one week, its position can be fixed through the threaded housing 12 and the screw 11, thereby preventing the protective housing 302 from sliding easily due to the water flow.

[0038] Further, the wiping assembly 10 includes two sets of transmission rods 102 and a rotating plate 109. The rotating plate 109 is rotatably installed between two sets of electric water spray heads 402. The two sets of transmission rods 102 are symmetrically and elastically arranged at both ends outside the transmission plate. Cleaning plates 101 are fixedly installed on both sides of the two sets of transmission rods 102, and the two cleaning plates 101 are respectively in contact with both ends inside the sampling chamber 6. Stepper motors 104 are fixedly installed at both ends inside the fitting groove, and a first gear 103 is fixedly installed at one end of the output shafts of the two stepper motors 104. A plurality of tooth grooves are formed in a circular and equally spaced manner on the outer circumference of the bearing plate 9, and the plurality of tooth grooves are all meshed with the first gear 103. A gasket 14 is fixedly installed at one end of the electric water spray head 402, and a second gear 108 is fixedly installed in the middle of one side of the gasket 14. The second gear 108 is horizontally arranged through the gasket 14. A driven gear 105 is meshed with one side of the second gear 108. A support frame 13 is rotatably connected to one side of the driven gear 105. The support frame 13 is fixedly connected to the inside of the fitting groove. Synchronous wheels 106 are fixedly installed in the middle of the opposite sides of the two driven gears 105. Another set of synchronous wheels 106 are rotatably connected to the middle of the opposite sides of the two second gears 108. A synchronous belt 107 is sleeved between the two synchronous wheels 106. The rotating plate 109 is rotatably connected to the second gear 108 through another set of synchronous wheels 106;

[0039] As Figures 3 to 7 shown, through the design that the driven gear 105 is meshed with one side of the second gear 108, based on the principle of the large gear driving the small gear between the second gear 108 and the driven gear 105, when the stepper motor 104 drives the electric water spray head 402 to rotate at an angle to spray and wet the inside of the sampling chamber 6, the driven gear 105 drives the rotating plate 109 to rotate at a high speed through the transmission of the second gear 108, so that the multiple cleaning plates 101 can rotate quickly, achieving the effect of quickly wiping the inside of the sampling chamber 6;

[0040] Due to the differential principle between the large gear and the small gear of the above-mentioned cleaning plate 101, the cleaning plate 101 can further assist in spreading the water during the spraying process to cover the inside of the sampling chamber 6, thereby better improving the cleaning effect of the cooperation between the wiping assembly 10 and the flushing assembly 4 on the inside of the sampling chamber 6;

[0041] At the same time, the above-mentioned electric water spray head 402 can rotate through the mutual cooperation of the first gear 103 and the bearing plate 9. Therefore, the electric water spray head 402 can spray water more comprehensively into the sampling chamber 6.

[0042] Further, two ends on the outside of the rotating plate 109 are symmetrically and fixedly installed with connecting rods 8. One end of the transmission rod 102 is provided with a sliding groove. One end of the connecting rod 8 is slidably installed inside the sliding groove, and one end of the connecting rod 8 is fixedly installed with a return spring 7. One end of the return spring 7 is fixedly connected to one end inside the sliding groove. The other end of the transmission rod 102 is arc-shaped;

[0043] As Figure 5 shown, through the design that one end of the return spring 7 is fixedly connected to one end inside the sliding groove, there is elasticity between the transmission rod 102 and the rotating plate 109, so that the transmission rod 102 can drive the cleaning plate 101 to fit inside the sampling chamber 6, so that the cleaning area of the cleaning plate 101 covers the whole inside of the sampling chamber 6. Therefore, the cleaning effect of the cleaning plate 101 on the inside of the sampling chamber 6 is effectively improved;

[0044] Through the design that the other end of the transmission rod 102 is arc-shaped as described above, the transmission rod 102 abuts against the inside of the sampling chamber 6. The transmission rod 102 can rely on the arc at the other end to reduce the friction with the inside of the sampling chamber 6, thereby further avoiding damage to the sampling chamber 6 when the transmission rod 102 moves.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
