Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning pipelines, and in particular relates to a constant-pressure cleaning pipeline adopting the Tesla valve principle. Background Art

[0002] Laboratories use a large number of plastic laboratory utensils (such as plastic test tubes, beakers, measuring cylinders, funnels, etc.) to conduct experiments, analyses, create chemical reactions, separations, and sampling. As research becomes more and more sophisticated and requirements become higher and higher, the cleanliness of laboratory utensils will directly affect the test results. Therefore, laboratory utensils are usually cleaned using a utensil washer to prevent chemical substances from causing harm to people's hands.

[0003] In a Chinese patent with publication number CN215543499U, a constant pressure cleaning and nursing device is disclosed. The patent includes a base plate, a disinfection tank, a pressure pump and a cleaning box are installed on the top of the base plate, a liquid extraction pipe is connected between the pressure pump and the disinfection tank, a liquid delivery pipe is connected between the pressure pump and the cleaning box, a cleaning ring pipe is installed on the inner wall of the cleaning box, the end of the liquid delivery pipe is connected to the cleaning ring pipe, the bottom of the cleaning ring pipe is connected to a cleaning nozzle, a filter plate is installed on the inner wall of the cleaning box, filter holes are opened on the filter plate, a rotating rod is rotatably connected to the inner wall of the cleaning box, a positioning frame is fixed to the end of the rotating rod, one end of the rotating rod rotates through the cleaning box and a driven wheel is installed, and the cleaning A motor is installed on the side wall of the box, and a driving wheel is installed on the output end of the motor. The driving wheel and the driven wheel are meshed. The inner wall of the cleaning box is connected to a liquid outlet pipe. By spraying cleaning and disinfection, the utensils can be disinfected, cleaned and cared for in an all-round manner, saving cleaning and disinfection time. However, when the above-mentioned constant pressure cleaning and care device is in use, the disinfectant flows into the cleaning nozzle through the infusion tube to clean the utensils. However, when cleaning the conical utensils, it is difficult for the cleaning nozzle to penetrate into the inside of the conical utensils for cleaning, so that the inside of the conical utensils needs to be cleaned repeatedly, which is cumbersome to use, increases the cleaning time, and wastes disinfectants.

[0004] In order to solve the above problems, the present application proposes a constant pressure cleaning pipeline using the Tesla valve principle. Utility Model Content

Through the water divider and the flow channel, waste water can flow slowly in the Tesla valve body after passing through the water outlet.

[0012] As a preferred constant pressure cleaning pipeline adopting the Tesla valve principle of the utility model, two flippable baffle plates are symmetrically arranged on the top of the cleaning box, and hinges are arranged between the cleaning box and the baffle plates. By flipping the baffle plates upwards and moving the baffle plates to the top of the cleaning box, waste water splashing during cleaning can be shielded.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Through the cooperation of the pressure pump, Tesla valve body and nozzle, the disinfectant is sprayed into the inside of the conical container through the water outlet of the nozzle, so that the inside of the conical container can be quickly cleaned, reducing the number of times the container is cleaned. The operation is simple, the cleaning time is reduced, the disinfectant is saved, and the cost is reduced;

[0018] 2. By moving the two clamping plates, the distance between the two clamping plates becomes larger, the two clamping plates drive the two telescopic rods to move, and the two telescopic rods drive the baffle to move, so that the baffle pushes the positioning rod to deform. After the utensils to be cleaned are placed between the two clamping plates, the positioning rod releases the elastic force, so that the two clamping plates clamp and fix the utensils, thereby facilitating the cleaning of utensils of different sizes.

[0028] As can be seen from the above, when in use, after placing the conical container to be cleaned into the cleaning box 1, turn on the pressure pump 3, the pressure pump 3 extracts the disinfectant in the disinfectant box 2 and transports it to the inside of the delivery pipe 9. After the disinfectant flows through the delivery pipe 9, it is sprayed out from the bottom plate 10 to clean the inside of the conical container.

[0031] By adopting the above technical solution:

[0032] When in use, the conical container is turned upside down and placed on the nozzle 6, and the pressure pump 3 is turned on. The pressure pump 3 flows the disinfectant in the disinfectant box 2 into the inside of the chassis 10 through the delivery pipe 9, so that the disinfectant in the chassis 10 quickly passes through the water inlet of the Tesla valve body 5 and then flows into the water outlet, so that the disinfectant is sprayed on the inside of the conical container through the water outlet of the nozzle 6, so that the inside of the conical container can be quickly cleaned;

[0033] At the same time, when the waste water after cleaning the conical vessel flows into the interior of the Tesla valve body 5 through the nozzle 6, the waste water is diverted by the water divider and then flows into the flow channel. The waste water inside the flow channel collides with the water flow trough to form a vortex, thereby slowing down the waste water and preventing the waste water from directly entering the interior of the chassis 10.

[0034] In addition, refer to Figure 1-Figure 4 As shown, two positioning rods 8 are symmetrically fixed to the top of the inner wall of the cleaning box 1, and two retractable telescopic rods 7 are arranged at one end of the two positioning rods 8 away from the cleaning box 1, and two clamping plates 4 are arranged at one end of the two telescopic rods 7 away from the two positioning rods 8; baffles are fixed to the ends of the two telescopic rods 7 away from the clamping plates 4, and sliding grooves matched with the baffles are opened on the two positioning rods 8, and the telescopic rods 7 can be limited by the cooperation of the baffles and the sliding grooves; a spring 11 is arranged between the baffles and the sliding grooves, and arc grooves are arranged on the opposite sides of the two clamping plates 4, and convex patterns are arranged on the inner walls of the arc grooves, and the friction between the clamping plates 4 and the utensils can be increased by the convex patterns.

[0035] By adopting the above technical solution:

[0036] When in use, the two clamping plates 4 are moved to increase the distance between the two clamping plates 4, the two clamping plates 4 drive the two telescopic rods 7 to move, and the two telescopic rods 7 drive the baffle to move, so that the baffle pushes the positioning rod 8 to deform, and after the utensils to be cleaned are placed between the two clamping plates 4, the positioning rod 8 releases the elastic force, so that the two clamping plates 4 clamp and fix the utensils, thereby facilitating the cleaning of utensils of different sizes.
