Description

Technical Field

[0001] This utility model relates to the technical field of bottled water sampling inspection devices, specifically to a bottled water sampling inspection device. Background Technology

[0002] In the bottled water industry, portable sampling inspection devices play a crucial role in quality control during the production process, supervision of market circulation, and protection of consumer rights. They can quickly and flexibly sample and test bottled water in different scenarios, and promptly identify potential quality problems.

[0003] The basic working principle of the portable bottled water sampling devices commonly found on the market is to insert a sampling tube into the bottle opening to extract water samples for subsequent testing. However, this design exposes a significant problem in practical applications. Since the bottle opening is usually larger than the outer diameter of the sampling tube, a certain gap inevitably forms between them. During the sampling process, this gap becomes a potential channel for external impurities to enter the bottle.

[0004] When operators use portable sampling devices to take samples, various impurities in the surrounding environment, such as dust in the air, floating microorganisms, and clothing fibers, can easily enter the bottled water through the gap between the sampling tube and the bottle mouth. Once these impurities enter, they will contaminate the originally pure water in the bottle, thereby interfering with the accuracy of the sampling test results. Utility Model Content

[0005] The purpose of this invention is to provide a bottled water sampling inspection device to solve the problem in the prior art that impurities can easily enter the bottle through the gap between the sampling tube of the bottled water sampler and the bottle mouth.

[0008] As a preferred embodiment of the above technical solution, the positioning component includes multiple sets of sleeves that penetrate the anti-fouling cover. Each set of sleeves has a spring fixedly installed inside it, and a connecting rod is fixedly installed at the end of the spring. A clamping plate is fixedly installed at the end of the connecting rod, and the clamping plate is located inside the anti-fouling cover.

[0009] As a preferred embodiment of the above technical solution, the clamping plate is wrapped with rubber and has serrated grooves.

[0010] As a preferred embodiment of the above technical solution, limit blocks are fixedly installed at the top ends of both sets of sliding rods.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a bottled water sampling and testing device, including a connecting shell 1, a water pump 3 fixedly installed on the connecting shell 1, a rubber hose 31 fixedly connected to the water pump 3, and a detector 32 fixedly connected to the end of the rubber hose 31. A first sampling tube 11 is fixedly connected to the bottom end of the connecting shell 1, and the first sampling tube 11 is interconnected with the water pump 3. A second sampling tube 12 is provided on the first sampling tube 11. An anti-fouling component 4 is provided on the connecting shell 1. The anti-fouling component 4 includes two sets of sliding rods 41 slidably installed on the connecting shell 1, and the ends of the two sets of sliding rods 41 are... A dirt cover 43 is fixedly connected and slidably installed on the first sampling tube 11. A positioning component 5 is provided on the dirt cover 43 for positioning the bottled water. Under the action of the water pump 3, the bottled water will enter the water pump 3 sequentially through the second sampling tube 12 and the first sampling tube 11, and then be transported to the detector 32 fixedly connected to the end of the rubber hose 31 via the rubber hose 31. The detector 32 will perform various index detection and analysis on the extracted water sample, such as physicochemical indexes and microbial content, so as to obtain the quality test results of the bottled water.

[0025] As one implementation method in this embodiment, such as Figure 4 and Figure 5 As shown, the positioning component 5 includes multiple sets of sleeves 54 that pass through the anti-fouling cover 43. Each set of sleeves 54 has a spring 53 fixedly installed inside it, and a connecting rod 52 is fixedly installed at the end of the spring 53. A clamping plate 51 is fixedly installed at the end of the connecting rod 52, and the clamping plate 51 is located inside the anti-fouling cover 43. The elasticity of the spring 53 allows the connecting rod 52 to contract or extend according to the size of the bottle opening, so that the clamping plate 51 can fit tightly against bottle openings of different sizes, thereby improving the versatility and applicability of the device.

[0026] As one implementation method in this embodiment, such as Figure 4 and Figure 5 As shown, the clamping plate 51 is covered with rubber and has serrated grooves. The rubber covering the clamping plate 51 can increase the friction between the clamping plate 51 and the bottle mouth, and the serrated grooves can further enhance the friction and biting force between the clamping plate 51 and the bottle mouth, thereby improving the stability of clamping.

[0027] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, limit blocks 42 are fixedly installed at the top of both sets of sliding rods 41. The limit blocks 42 can limit the sliding range of the sliding rods 41 on the connecting shell 1, prevent the sliding rods 41 from falling off the connecting shell 1 when sliding upward, and ensure the safety and reliability of the device.

[0028] As one implementation method in this embodiment, such as Figure 2 and Figure 3 As shown, the inner wall of the first sampling tube 11 is provided with internal threads, and the second sampling tube 12 is connected to a connecting tube 13, which is provided with external threads. The second sampling tube 12 is fixedly connected to the first sampling tube 11 through the connecting tube 13 and is fixed together by threaded connection. This connection method is simple and reliable, and it is convenient for operators to disassemble and replace the second sampling tube 12 as needed, and it is convenient to clean the inside of the first sampling tube 11 and the second sampling tube 12.

[0029] As one implementation method in this embodiment, such as Figure 5As shown, two sets of locking rings 7 are fixedly installed on the connecting shell 1. Each set of locking rings 7 has multiple vertical through slots 71, on which locking sleeves 6 are rotatably installed. The top of the locking sleeve 6 is conical, and the locking sleeve 6 is threadedly connected to the locking rings 7. When the locking sleeve 6 is rotated, the conical top of the locking sleeve 6 exerts a squeezing effect on the locking rings 7, thereby locking the connecting shell 1 and the sliding rod 41 together. This prevents relative sliding between the connecting shell 1 and the sliding rod 41 during sampling inspection, ensuring the safety of the anti-fouling cover. The positions of the 43 and the sampling tube are stable. The multiple sets of vertical through grooves 71 on the locking ring 7 provide a certain deformation space for the locking ring 7. When the conical top of the locking sleeve 6 squeezes the locking ring 7, the locking ring 7 can undergo slight deformation, thereby clamping the sliding rod 41 more tightly and improving the reliability of locking. By rotating the locking sleeve 6 in the opposite direction, the compression of the conical top of the locking sleeve 6 on the locking ring 7 can be released, thereby unlocking the connecting shell 1 from the sliding rod 41. The operator can easily adjust the position of the anti-fouling cover 43 and the sampling tube to adapt to different sampling needs.

[0030] As one implementation method in this embodiment, such as Figure 1 As shown, handles 2 are fixedly installed at both ends of the connecting shell 1. The handles 2 provide a comfortable grip for the operator. The operator can hold the handles 2 with both hands to easily operate the entire sampling device, such as moving the device, adjusting the position of the anti-fouling cover 43 and the sampling tube, etc.

[0031] Working principle: When conducting bottled water sampling inspection, the operator must first open the bottle cap of the bottled water to be tested to prepare for the subsequent sampling inspection operation.

[0032] Subsequently, the anti-fouling cover 43 is precisely snapped onto the outside of the bottle opening. Since the sizes of the bottle openings of different bottled water bottles may vary, the positioning component 5 in the anti-fouling component 4 begins to function. When the anti-fouling cover 43 is snapped onto the outside of the bottle opening, the clamping plate 51 will contact the bottle opening. Under the elastic action of the spring 53, the connecting rod 52 can retract or extend accordingly according to the size of the bottle opening, so that the clamping plate 51 can fit tightly against bottle openings of different sizes, thereby firmly clamping the bottle opening and ensuring that the anti-fouling cover 43 remains stable during the sampling inspection. In addition, the clamping plate 51 is covered with rubber and has serrated grooves. The rubber material can increase the friction between the clamping plate 51 and the bottle opening, and the serrated grooves further enhance this friction effect, improve the stability of the clamping, and ensure the smooth progress of the sampling inspection operation.

[0033] After the anti-fouling cover 43 is installed and positioned, the connecting shell 1 and the sliding rod 41 need to be unlocked to adjust the depth of the second sampling tube 12 inserted into the bottle. Two sets of locking rings 7 are fixedly installed on the connecting shell 1. Multiple vertical slots 71 are formed on the locking rings 7, and locking sleeves 6 are rotatably installed on these slots. The top of the locking sleeve 6 is conical. Initially, the conical top of the locking sleeve 6 exerts a squeezing effect on the locking ring 7, locking the connecting shell 1 and the sliding rod 41, preventing relative sliding. At this point, the operator rotates the locking sleeve 6. As the locking sleeve 6 rotates, its conical top gradually releases the squeezing of the locking ring 7. The locking ring 7 recovers to a certain state due to its own elasticity or structural characteristics, thereby releasing the lock between the connecting shell 1 and the sliding rod 41, allowing them to slide relative to each other.

[0034] After unlocking, the operator holds the handles 2 at both ends of the connecting shell 1 with both hands and slowly and steadily pushes the connecting shell 1 downward. Since the first sampling tube 11 is fixedly connected to the bottom of the connecting shell 1, and the first sampling tube 11 and the second sampling tube 12 are fixedly connected through the connecting tube 13, by controlling the downward pushing force and distance, the operator can accurately adjust the depth of the second sampling tube 12 into the bottle, thereby realizing the sampling and detection of water layers at different depths.

[0035] Once the second sampling tube 12 reaches the appropriate depth, the water pump 3 is started. The water pump 3 is fixedly installed on the connecting shell 1 and is interconnected with the first sampling tube 11. The first sampling tube 11 is also connected to the second sampling tube 12. Under the action of the water pump 3, bottled water will sequentially enter the water pump 3 through the second sampling tube 12 and the first sampling tube 11, and then be transported to the detector 32, which is fixedly connected to the end of the rubber hose 31, via the rubber hose 31 fixedly connected to the water pump 3. The detector 32 will perform various index detection and analysis on the extracted water sample, such as physicochemical indexes and microbial content, thereby obtaining the quality test results of the bottled water.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
