Description

Technical Field

[0001] This utility model relates to the technical field of laboratory glassware cleaning brushes, and in particular to a laboratory glassware cleaning brush. Background Technology

[0002] In scientific experiments such as drug research and electrochemical experiments, various glassware such as test tubes, beakers, conical flasks, and volumetric flasks are widely used in laboratories for sample storage and reaction. After the experiment, these glasswares need to be thoroughly cleaned to prevent residual reagents from contaminating subsequent experiments and to ensure the precision and accuracy of analytical test data. Traditional cleaning methods often rely on manual scrubbing with hand-held brushes or sponges, which is not only time-consuming and labor-intensive, but also difficult to guarantee the cleaning effect, and carries the risk of cross-contamination due to incomplete cleaning.

[0003] Existing cleaning brushes have significant limitations: First, most cleaning brushes are single-function and lack adjustability, making them difficult to adapt to glassware of different diameters, depths, and special shapes (such as the shoulder of a conical flask or the narrow mouth of a volumetric flask), resulting in blind spots during cleaning; Second, the addition of cleaning agents relies on manual external application, which is difficult to control the amount used and is cumbersome and inefficient; Third, although ultrasonic cleaning technology exists, it is mostly used in large tank-type equipment, which is powerful, noisy, and unsuitable for immediate and precise cleaning of a small number of or specific containers.

[0004] Furthermore, while laboratory management is becoming increasingly intelligent, the digitalization level of equipment cleaning tools remains low. Traditional brushes cannot record the cleaning process, monitor the remaining amount of consumables (such as cleaning agents), or be integrated into a Laboratory Information Management System (LIMS), thus failing to meet the data traceability and process monitoring needs of modern smart laboratories.

[0005] Therefore, those skilled in the art urgently need an intelligent cleaning brush that can integrate efficient cleaning, intelligent sensing, status monitoring, and is adaptable to a variety of containers, in order to improve cleaning efficiency, effectiveness, and the level of intelligence in laboratory management.

[0019] like Figure 1This is a schematic diagram of the structure of this utility model: a laboratory glassware cleaning brush, including a brush head 1, a brush handle 2, bristles 3, a built-in detergent storage cavity 4, a small scraper 5, an ultrasonic generator 6, and an automatic sensing device 7. The brush head 1 is connected to one end of the brush handle 2, the bristles 3 are disposed on the surface of the brush head 1, the built-in detergent storage cavity 4 is disposed inside the brush handle 2, the small scraper 5 is installed on the side of the brush head 1, the ultrasonic generator 6 is integrated inside the brush head 1, and the automatic sensing device 7 is installed on the front side of the brush handle 2. The brush also includes a main control unit 8, a sensor module 9, a communication module 10, and a cloud platform connection module 11; the main control unit... 8. An STM32 series microcontroller is integrated inside the brush handle 2 to control the overall operation of the brush; the sensor module 9 includes an infrared transceiver sensor and a pressure sensor. The infrared transceiver sensor is installed at the front end of the brush head 1 to detect the distance between the brush and the glassware, and the pressure sensor is integrated at the bottom of the detergent storage chamber 4 to monitor the remaining detergent level; the communication module 10 uses a WiFi module to support wireless data transmission with mobile terminals or the cloud; the cloud platform connection module 11 connects to the cloud server through the communication module 10 to remotely monitor the brush status; the brush handle 2 adopts a retractable structure wrapped in soft rubber.

[0020] According to another embodiment of the present invention, the infrared transceiver sensor of the sensor module 9 is a TCRT5000 infrared reflection sensor, which is used to detect the distance between the brush and the glassware. When the distance is less than a set threshold, the automatic sensing device 7 is triggered to work. The pressure sensor is an HX711 24-bit A / D converter chip, which is used to monitor the remaining amount of cleaning agent in real time and transmit the data to the cloud platform through the communication module 10.

[0021] Specifically, the infrared transceiver module uses the TCRT5000 infrared reflection sensor, primarily used for black-and-white detection and obstacle detection. The TCRT5000 sensor's infrared emitting diode continuously emits infrared light. When the emitted infrared light is not reflected back or the reflected light is not strong enough, the infrared receiving diode remains in a non-conductive state. In this case, the module's output voltage remains high, indicating that the diode is inactive. When the monitored object enters the monitoring area, the infrared light is reflected back with sufficient intensity, causing the infrared receiving diode to saturate. At this time, the module's output will show a low voltage, indicating that the diode has been activated. The HX711 is a 24-bit A / D converter chip designed specifically for high-precision electronic scales. It can quickly convert analog signals into digital signals and has advantages such as high integration, fast response speed, and strong anti-interference capabilities. All control signals of the HX711 are driven by pins; therefore, simply connecting the chip's SDA and SCK pins to the STM32 microcontroller's pins (PC4 and PC5) is sufficient to drive the module. Data transmission in this process is performed via I²C.

[0022] According to another embodiment of the present invention, the communication module 10 is a USR-C216 WiFi module that supports the 802.11b / g / n protocol and is connected to the main control unit 8 through a UART interface to realize wireless communication between the brush and the mobile terminal; the cloud platform connection module 11 integrates the Tuya IoT cloud service or the Manned Cloud Platform, which is used to receive data from the sensor module 9 and display the remaining status, cleaning records and alarm information through a mobile APP.

[0023] According to another embodiment of the present invention, the brush further includes an integrated voice recognition module. This module uses an HLK-V20 core chip and is connected to the main control unit 8 via a serial port. It is used to recognize user voice commands and control the brush to start / stop or switch modes.

[0024] Specifically, the HLK-V20 was chosen as the core chip. This is a highly efficient AI acceleration architecture with a high degree of coupling between hardware and algorithms. The module uses a 32-bit RISC core and integrates a DSP, a specific signal processing and speech recognition tool. It also features an FPU (Flexible Processing Unit) and an FFT accelerator, using neural network algorithms to train and learn from audio information, thereby enhancing its recognition capabilities. The speech recognition module supports serial communication with the MCU. After recognizing a voice command, the module outputs the corresponding protocol data via the serial port. Upon receiving data from the speech recognition module, the MCU's serial port can execute the corresponding operations based on the commands. The speech module operates on 5V power and has an average standby power consumption of 63mA.

[0025] According to another embodiment of the present invention, the automatic sensing device 7 further includes an infrared sensor or a proximity sensor with a sensing distance of 1-5cm, which automatically activates the ultrasonic generator 6 when a glass container is detected; the ultrasonic generator 6 has a frequency of 20-40kHz and a power of 5-10W, and is powered by a built-in battery in the brush handle 2.

[0026] According to another embodiment of the present invention, the brush head 1 is further comprising a replaceable multi-type design, including round, square, triangular and irregularly shaped brush heads; the bristles 3 are arranged in layers or staggered; the irregularly shaped brush head 1 includes a conical or arc-shaped design, specifically adapted to the shoulder of a conical bottle or the narrow mouth of a volumetric flask; in the layered or staggered arrangement of the bristles 3, the outer layer bristles are longer than the inner layer bristles, the density is 80-120 bristles / cm², and the edge of the brush head 1 is provided with inclined or curved bristles.

[0027] According to another embodiment of the present invention, the retractable structure of the brush handle 2 is adjusted in length by means of threads or buckles, with an adjustment range of 20-40cm; the soft rubber coating material of the brush handle 2 is silicone or thermoplastic elastomer TPE with a thickness of 2-5mm to increase friction and reduce hand fatigue.

[0028] According to another embodiment of the present invention, the built-in cleaning agent storage chamber 4 is connected to the brush head 1 via a micro pump or capillary tube, and the storage chamber has a capacity of 10-30ml; the small scraper 5 has a width of 2-5mm and is made of polyurethane rubber; the entire brush is waterproofed, and the brush bristles 3 and the brush handle 2 are coated with a nano-hydrophobic coating.

[0029] For first-time use or after a long period of inactivity, please charge the built-in battery of brush handle 2. Check that the bristles 3 are intact and that the connection between brush head 1 and brush handle 2 is secure. Confirm that the detergent storage chamber 4 is filled with an appropriate amount of laboratory-grade detergent. Select the appropriate brush head 1 (square, triangular, or irregularly shaped) and install it onto brush handle 2 according to the shape of the vessel to be cleaned (e.g., narrow-mouth conical flask, wide-mouth beaker). Turn on the brush power. If the brush has an integrated voice recognition module, you can start the connection by speaking a preset command (e.g., "Start pairing"); otherwise, start it via the button on brush handle 2. Open the mobile app and ensure a normal WiFi network connection. Add the device in the app and follow the prompts to complete the pairing of the brush (via communication module 10) with the mobile terminal and cloud platform (via cloud platform connection module 11). Set the cleaning parameters in the app, such as the detergent level alarm threshold, ultrasonic working mode (standard / powerful), and default cleaning duration. Hold brush handle 2 and bring brush head 1 close to the mouth of the vessel to be cleaned. When the automatic sensing device 7 (such as an infrared / proximity sensor) detects a vessel within 1-5cm, it automatically activates the ultrasonic generator 6 (frequency 20-40kHz) and the detergent supply system (from the built-in detergent storage chamber 4), without requiring manual button presses. Insert the brush head 1 into the vessel and slowly move it up and down or rotate it along the inner wall to ensure that the bristles 3 contact all areas. The layered, staggered bristles 3 and the small scraper (5) effectively remove stubborn stains and residues. During the cleaning process, the micro-pump or capillary in the built-in detergent storage chamber 4 will squeeze out detergent as needed, which, combined with the ultrasonic cavitation effect, enhances the cleaning effect. For particularly difficult-to-clean areas (such as the shoulder of a conical flask), you can pause briefly or use the APP to control and increase the power of the ultrasonic generator 6. The entire cleaning process is coordinated and controlled by the main control unit 8 (STM32 series microcontroller). During operation, you can view the data of the sensor module 9 in real time through the APP, such as the remaining detergent (monitored by the HX711 pressure sensor) and the duration of this cleaning. If temporary adjustments are needed, the mode can be switched via the app (e.g., from standard wash to intensive wash), or controlled via voice commands (e.g., "stop," "increase power") (if a voice recognition module is integrated). After cleaning, remove the brush. The automatic sensor 7 will detect the brush leaving the container and automatically stop working after a short delay. Rinse the container and brush head 1 with clean water to ensure that detergent and dirt are completely removed. Gently shake off excess water from the brush head 1.

[0030] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
