[0002] Portable laboratory pH testing devices are miniaturized testing equipment that integrates pH sensing, signal processing, and data display functions. They are characterized by their small size, light weight, portability, and on-site operation. They can quickly and conveniently measure the acidity or alkalinity of liquid samples and are widely used in scenarios that require real-time pH data, such as environmental monitoring, water quality analysis, food processing, and agricultural production. They retain the detection accuracy of laboratory-level instruments while overcoming the limitations of traditional large instruments that require fixed locations and complex operations, thus meeting the needs of rapid on-site testing.

[0003] However, the existing testing devices lack reasonable protection and convenient placement methods for components such as test pens during storage and use. Randomly placing test pens can easily damage electrodes and affect testing accuracy. At the same time, the storage of connecting wires is also quite messy, and they are easy to get tangled and knotted. Finding and organizing the wires during use takes a lot of time. Utility Model Content

[0004] The purpose of this invention is to provide a foldable and portable laboratory pH testing device to solve the problems mentioned in the background art, such as the lack of reasonable protection and convenient placement of components like the test pen during storage and use. Random placement of the test pen can easily lead to electrode damage and affect the detection accuracy. At the same time, the storage of connecting wires is also messy and easy to get tangled and knotted, which takes a lot of time to find and organize the wires during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable and portable laboratory pH detection device, comprising a pH detection device body;

[0006] A back plate is provided at the rear of the main body of the pH detection device, a test pen is provided inside the back plate, and an electrode is provided at the bottom of the test pen.

[0007] A test pen placement cavity is provided on the left side of the back plate, and a wire cavity is provided on the right side of the back plate.

[0008] Preferably, a protective sleeve is provided above the test pen placement cavity, and an insertion hole is provided inside the protective sleeve, through which the electrode can be plugged and connected.

[0009] Preferably, a handheld component is provided at the front of the top of the test pen, and the top of the handheld component is provided with anti-slip texture.

[0010] Preferably, a sliding groove is provided on the left and right sides of the inside of the test pen placement cavity, and a positioning strip corresponding to the sliding groove is provided on the left and right sides of the test pen.

[0011] Preferably, the sheath is made of artificial rubber, and an insulating shell is provided on the outer side of the test pen.

[0012] Preferably, a wire is folded and disposed inside the wire cavity, and a bottom groove is disposed below the wire cavity.

[0013] Preferably, a connector is provided at the end of the wire, and a plug slot is provided at the top of the test pen, and the wire is connected to the plug slot through the connector.

[0015] Compared with the prior art, this utility model provides a foldable and portable laboratory pH testing device, which has the following advantages:

[0016] 1. Through the design of the test pen placement cavity, protective sleeve, insertion hole, handheld component, anti-slip texture, sliding groove, positioning strip, and insulating shell, the test pen placement cavity on the left side of the back panel and the lead wire cavity on the right side achieve partitioned storage of important components in the testing device. This makes the overall structure of the device compact and orderly. During carrying, the test pen and lead wire are placed in their respective cavities, avoiding mutual collision and entanglement, protecting the components and facilitating access, thus improving the portability and ease of use of the device. The protective sleeve above the test pen placement cavity and its internal insertion hole provide a dedicated protective space for the electrodes. When stored, the electrodes are inserted into the insertion hole, preventing them from being damaged by external impacts, scratches, and dust contamination, effectively extending the life of the electrodes and ensuring testing accuracy. The handheld component on the front of the test pen and the anti-slip texture on the top of the handheld component... The anti-slip texture greatly improves the user's grip experience when using the test pen. The increased friction between the hand and the grip prevents the pen from slipping during operation, enhancing stability and safety. The sliding grooves on both sides of the test pen's placement cavity work in conjunction with corresponding positioning strips on both sides of the pen, making insertion and removal smoother and more secure. The positioning strips slide along the grooves to precisely position the pen, preventing it from shaking or shifting within the cavity, further protecting the pen and its electrodes. The artificial rubber sheath is flexible and elastic, better conforming to the electrodes and providing cushioning protection. The insulating shell on the outside of the pen ensures user safety during operation, preventing the risk of electric shock and ensuring a safe and reliable operating environment.

[0017] 2. Through the design of the wire cavity, wire, bottom groove, connector, and plug-in slot, the wire cavity provides a dedicated storage space for the wires, allowing them to be neatly folded and placed inside. This prevents the wires from scattering when not in use, avoiding tangling and knots, and facilitating quick and easy retrieval when needed, improving work efficiency. It also protects the wires from excessive pulling and damage, extending their lifespan. The bottom groove at the bottom of the wire cavity holds the connector, preventing loss and facilitating quick retrieval when maintaining or replacing wire components, enhancing the device's functionality and practicality. The connector at the end of the wire connects to the plug-in slot on top of the test pen using a plug-in connection, providing a stable connection and simple operation. This plug-in structure ensures a good electrical connection between the wire and the test pen, guaranteeing stable signal transmission and improving the accuracy of the test data. Furthermore, the plugging and unplugging operation is simple and quick when needed, requiring no complicated tools or steps, reducing the difficulty of use and improving the device's usability.

Since the maintenance door 5 is provided with a disassembly groove 6 on the side, it can be disassembled when needed to make it easier to take out the test pen 11. The positioning strips 17 on the left and right sides of the test pen 11 slide out along the sliding grooves 15 on the left and right sides inside the test pen placement cavity 20, thereby taking out the test pen 11. Take out the folded wire 13 from the wire cavity 12. Insert the connector 14 at the end of the wire 13 into the insertion slot 18 at the top of the test pen 11 to complete the connection between the wire 13 and the test pen 11. Hold the handhold 8 on the front of the top of the test pen 11. The anti-slip texture 10 on the handhold 8 can increase the grip stability and prevent the test pen from slipping. Remove the electrode 16 at the bottom of the test pen 11 from inside the protective sleeve 9. Pull the electrode 16 out of the socket 19. The sheath 9, made of artificial rubber, protects the electrode 16. Place the electrode 16 into the solution to be tested. Start the testing program by controlling the control button 3 at the bottom of the display screen 2 on the upper front side of the main body of the pH detection device 1. Insert the electrode 16 into the socket 19 inside the sheath 9 to protect it. Then slide the test pen 11 into the test pen placement cavity 20 along the slide groove 15, ensuring that the positioning strip 17 and the slide groove 15 are accurately matched to securely place the test pen 11. Remove the lead wire 13 from the test pen 11, fold the lead wire 13 neatly, and put it back into the lead wire cavity 12. The bottom groove 7 below the lead wire cavity 12 can help organize the lead wire 13 or place spare small parts. Close the maintenance door 5 on the outside of the test pen placement cavity 20 to complete the storage of the entire detection device for the next use.

[0036] like Figure 2-5 As shown, a test pen placement cavity 20 is provided on the left side of the back plate 4, a wire cavity 12 is provided on the right side of the back plate 4, a sheath 9 is provided above the test pen placement cavity 20, and an insertion hole 19 is provided inside the sheath 9. The electrode 16 can be inserted and connected to the insertion hole 19. A handhold 8 is provided on the front of the top of the test pen 11, and anti-slip texture 10 is provided on the top of the handhold 8. Slide grooves 15 are provided on the left and right sides of the inside of the test pen placement cavity 20, and positioning strips 17 corresponding to the slide grooves 15 are provided on the left and right sides of the test pen 11. The sheath 9 is made of artificial rubber, and an insulating shell is provided on the outside of the test pen 11.

[0037] Preferably, the test pen placement cavity 20 on the left side of the back panel 4 and the lead wire cavity 12 on the right side enable partitioned storage of important components in the testing device, making the overall structure of the device compact and orderly. During carrying, the test pen 11 and lead wire 13 are placed in their respective cavities, avoiding mutual collision and entanglement, protecting the components and facilitating access, thus improving the portability and ease of use of the device. The protective sleeve 9 above the test pen placement cavity 20 and its internal insertion hole 19 provide a dedicated protective space for the electrode 16. When stored, the electrode 16 is inserted into the insertion hole 19, which can prevent the electrode 16 from being impacted, scratched, or contaminated by dust, effectively extending the service life of the electrode 16 and ensuring testing accuracy. The handhold 8 on the front of the top of the test pen 11 and the anti-slip texture 10 on the top of the handhold 8 greatly improve the user's grip on the test pen 11. For improved grip during operation, the anti-slip texture 10 increases friction between the hand and the handheld component 8, preventing the test pen 11 from accidentally slipping during operation and improving operational stability and safety.

[0039] Preferably, the lead cavity 12 provides a dedicated storage space for the lead wire 13, allowing the lead wire 13 to be neatly folded and placed inside. This prevents the lead wire 13 from scattering when not in use, avoiding tangling and knotting. It also facilitates quick and smooth removal when needed, improving work efficiency. Furthermore, it protects the lead wire 13 from excessive pulling or damage, extending its service life. The bottom groove 7 located at the bottom of the lead cavity 12 holds the connector, preventing loss and facilitating quick retrieval when maintaining or replacing lead wire components, enhancing the functionality and practicality of the device. The connector 14 at the end of the lead wire 13 is connected to the insertion slot 18 at the top of the test pen 11 via a plug-in connection, providing a stable connection and easy operation. This plug-in structure ensures a good electrical connection between the lead wire 13 and the test pen 11, ensuring stable signal transmission and improving the accuracy of the test data. Additionally, the plugging and unplugging operation is simple and quick when needed, requiring no complicated tools or steps, reducing the difficulty of use and improving the ease of use of the device.

[0040] like Figure 1-4 As shown, a maintenance door 5 is provided on the outside of the test pen placement cavity 20, a disassembly groove 6 is provided on the side of the maintenance door 5, a display screen 2 is provided on the upper front side of the pH detection device body 1, and a control button 3 is provided at the bottom of the display screen 2.
