Description

Technical Field

[0001] This utility model relates to experimental cleaning equipment in the fields of chemical analysis and soil testing, and in particular to a simple electric rinsing device for test tubes used in organic matter testing. Background Technology

[0002] In many scientific research and experimental fields such as chemical analysis and soil testing, organic matter detection is a crucial task. As a commonly used experimental instrument, the cleaning effect of test tubes directly affects the accuracy and reliability of the test results. In the early days, researchers mainly relied on manually cleaning test tubes with test tube brushes. This method was not only inefficient, but the cleaning quality also depended on the skill level of the operator. It was difficult to thoroughly remove some hard-to-reach corners and stubborn stains, which could easily lead to cross-contamination and affect subsequent experiments.

[0003] With advancements in technology and increasing experimental demands, test tube cleaning technology is gradually evolving towards automation and intelligence. Various types of test tube cleaning equipment have emerged on the market, such as spray cleaners, which use high-pressure nozzles to spray cleaning fluid onto the inner and outer walls of test tubes to achieve cleaning; and ultrasonic cleaners, which utilize the cavitation effect of ultrasound to generate and break tiny bubbles in the cleaning fluid, thereby impacting the dirt on the test tube surface. However, these devices suffer from problems such as complex structure, high cost, and poor cleaning effectiveness for specific stains.

[0004] Manual cleaning: Researchers manually clean test tubes using a tube brush, relying on experience and skill to apply the cleaning solution to all parts of the tube to remove stains. This method is simple to operate, but it is inefficient, labor-intensive, and the cleaning effect varies from person to person, making it difficult to guarantee consistent cleaning quality.

[0005] Spray cleaning equipment: This type of equipment uses multiple nozzles, with a water pump pressurizing the cleaning solution before spraying it out from the nozzles to create a high-pressure spray that rinses the inner and outer walls of the test tubes. Its advantages include a high degree of automation and the ability to clean multiple test tubes simultaneously. However, the equipment has a complex structure, can create blind spots, is less effective at cleaning stubborn stains, and is relatively expensive.

[0006] Ultrasonic cleaners utilize an ultrasonic generator to produce high-frequency vibrations, which generate numerous tiny bubbles in the cleaning solution. When these bubbles burst on the surface of the test tube, they create impact force that removes dirt. Their advantage is that they can clean even tiny crevices and hidden areas. However, their effectiveness is limited for test tubes with complex shapes and small diameters, and they may not completely remove organic residues. Furthermore, they consume a relatively high amount of energy.

[0007] Rotary cleaning devices: These typically use a motor to drive the test tube brush or cleaning head to rotate and clean the inner wall of the test tube. However, they generally only clean the inner wall of the test tube and are not very effective at cleaning the outer wall. In addition, they are mostly used for cleaning single test tubes and cannot meet the needs of cleaning multiple test tubes at the same time.

[0008] In the field of organic matter detection, traditional cleaning equipment struggles to meet the requirements for deep cleaning due to the complex composition of residual organic matter in test tubes. This invention addresses this issue by developing a simple, electric-powered test tube rinsing device for organic matter detection. Its aim is to achieve efficient cleaning of test tubes with a simple structure and low cost, overcoming the shortcomings of existing cleaning technologies in cleaning test tubes for organic matter detection. Summary of the Invention

[0009] The purpose of this invention is to provide a simple, reasonable, cost-effective, and economical electric rinsing device for organic matter detection test tubes that can simultaneously clean multiple test tubes inside and out, is highly efficient in cleaning, and is portable as a whole.

[0010] This utility model discloses a simple electric rinsing device for organic matter detection test tubes, including a barrel body, a fixing frame and a support plate inside the barrel body, the fixing frame being mounted on the support plate; multiple support arms are connected to the four sides of the fixing frame, each support arm having a test tube fixing seat at its end, each test tube fixing seat having an outer wall test tube brush and an inner wall test tube brush, the outer wall test tube brush being positioned around the inner wall test tube brush at a distance, the outer wall test tube brush being connected to an outer wall brush drive wheel via a drive shaft; the inner wall test tube brush extending downwards and connected to an inner wall brush drive wheel.

The support plate is equipped with a motor B and a transmission device B. The outer wall test tube brushes are all driven by the motor A to rotate counterclockwise, and the inner wall test tube brushes are all driven by the motor B to rotate clockwise.

Multiple inner wall brush drive wheels are connected via a transmission chain, and the drive wheel B drives each inner wall brush drive wheel to rotate synchronously.

[0016] Preferably, the support arm is a solid plate or a plate with a perforated mesh.

[0017] Working principle of this utility model:

[0018] In organic matter detection experiments, test tube cleaning is a crucial step, but existing cleaning technologies have many drawbacks. Manual cleaning is inefficient and produces inconsistent quality, relying on manual operation and making it difficult to meet the needs of large-scale experiments; spray cleaning equipment has a complex structure, high cost, and is prone to leaving cleaning dead spots; ultrasonic cleaners are ineffective at cleaning stubborn organic matter and consume a lot of energy; traditional rotary cleaning devices only clean the inner wall and cannot process multiple test tubes simultaneously.

[0019] This invention aims to solve the aforementioned problems by providing a simple, low-cost, electrically operated test tube rinsing device for organic matter detection. Through innovative design, two motors drive the inner and outer test tube brushes respectively. One motor rotates clockwise to drive the inner brush, and the other counterclockwise to drive the outer brush. This allows for efficient cleaning of the inner and outer walls of up to eight test tubes simultaneously. The cleaning solution is carried from the bottom to all parts of the test tube, thoroughly removing organic residues, improving cleaning efficiency and quality, reducing labor intensity and experimental costs, and meeting the practical needs of various laboratories for test tube cleaning.

[0020] The present invention relates to a simple electric rinsing device for organic matter testing tubes, which mainly consists of a driving, cleaning, and fixing component.

[0021] Drive components: Equipped with two micro motors. Motor A is connected to a rechargeable power source and drives the internal cleaning shaft to rotate clockwise via belt drive. Motor B is also connected to a power source and drives the external cleaning shaft to rotate counterclockwise via belt drive, providing power for the cleaning operation.

[0022] Cleaning components: Both the internal and external cleaning shafts have eight mounting positions arranged in an array, for installing internal and external test tube brushes respectively. A large cleaning solution tank is located at the bottom of the device, containing a mixture of cleaning solution and detergent, for the cleaning brushes to absorb the cleaning solution.

[0023] Fixing components: Equipped with a dedicated test tube holder with 8 test tube placement holes to stabilize the test tubes to be cleaned, ensuring that the test tubes will not shake or shift during cleaning, thus ensuring smooth cleaning and achieving efficient cleaning of the inner and outer walls of 8 test tubes simultaneously.

[0024] Key technical features of this utility model:

[0025] 1. Dual-motor drive design: Innovatively employing two motors, one driving the internal test tube brush clockwise and the other driving the external test tube brush counter-clockwise, achieves simultaneous, reverse cleaning of the inner and outer walls of the test tubes. This ensures the cleaning solution evenly covers all parts of the test tubes, thoroughly removing organic residue. 2. Simultaneous multi-tube cleaning structure: An array-type cleaning shaft and mounting bracket are designed to clean up to eight test tubes simultaneously, greatly improving cleaning efficiency and meeting the batch cleaning needs of laboratories. Precise alignment of the cleaning shaft and mounting bracket ensures stable cleaning process.

[0027] 1. Add speed control function: Add a speed controller to the motor control circuit to adjust the motor speed according to the degree of contamination of the test tubes. For example, when cleaning lightly contaminated test tubes, the speed can be reduced to avoid damaging the test tubes; when cleaning heavily contaminated test tubes, the speed can be increased to enhance the cleaning effect.

[0028] 2. Improved cleaning solution tank: Install heating wires at the bottom of the cleaning solution tank, set the temperature through a thermostat, heat the cleaning solution, accelerate the dissolution of organic matter, and further improve cleaning efficiency and quality.

[0029] Compared with existing technologies, this utility model is a simple, reasonable, cost-effective, and economical electric washing device for organic matter detection test tubes that can simultaneously clean the inside and outside of test tubes, making the cleaning process highly efficient and portable. Its technical solution brings many significant benefits:

[0030] (1) High-efficiency cleaning: It can clean 8 test tubes at the same time. Compared with manual cleaning and single-tube cleaning equipment, it greatly improves the cleaning efficiency, meets the batch cleaning needs in the experiment, significantly shortens the cleaning time, and improves the experimental process.

[0031] (2) Thorough cleaning: Two motors drive the inner and outer test tube brushes respectively, one clockwise and one counterclockwise, to bring the cleaning solution to all parts of the inner and outer walls of the test tubes, cleaning all-round without dead angles, thoroughly removing organic residues, and the cleaning quality is far higher than that of traditional methods, ensuring the accuracy of subsequent experiments.

[0032] (3) Low cost: It adopts simple motors, belt drives and common cleaning components, with simple structure and low manufacturing cost. Compared with complex spray and ultrasonic cleaning equipment, the purchase and maintenance costs are greatly reduced, which alleviates the economic burden of the laboratory.
