Description

Technical Field

[0001] The present invention relates to the technical field of pH meter cleaning, in particular to a pH meter cleaning and wiping mechanism and a cleaning device. Background Art

[0002] A pH meter is an instrument used to measure the pH value of a solution. It operates based on the principle of a galvanic cell. The electromotive force between the two electrodes of a galvanic cell is related to both the electrode properties and the hydrogen ion concentration in the solution, according to Nernst's law. There is a corresponding relationship between the electromotive force of the galvanic cell and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. A pH meter is a common analytical instrument widely used in agriculture, environmental protection, and industry. Soil pH is one of the most important basic properties of soil. Factors such as the temperature and ionic strength of the solution being tested should be considered during pH measurement.

[0003] The existing technical solutions have the following shortcomings: the existing pH meter cleaning device can only clean the pH meter unilaterally, and lacks a structure for wiping after cleaning. As a result, after cleaning, the cleaning liquid will adhere to the surface of the pH meter and drip onto the workbench, causing inconvenience to the staff and hindering the smooth progress of subsequent work. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the pH meter cleaning device can only clean the pH meter unilaterally, but lacks a structure for wiping after cleaning.

[0005] The above technical problems are solved by the following technical solutions: The present invention proposes a pH meter cleaning and wiping mechanism, which includes a driving mechanism for driving the pH meter main body device to move in a vertical direction; a moving mechanism connected to the driving mechanism, for driving the pH meter main body device to move in a horizontal direction; a fixed clamping mechanism installed at the end of the moving mechanism, for detachably fixing the pH meter main body device to be cleaned; a cleaning component, including a first cleaning unit for achieving cleaning through non-contact energy transfer; and a second cleaning unit for achieving surface wiping through physical contact.

[0006] In a preferred embodiment of the pH meter cleaning and wiping mechanism of the present invention: a mounting base is fixed on the instrument body.

[0007] In a preferred embodiment of the pH meter cleaning and wiping mechanism of the present invention: the driving mechanism includes a first motor, which is fixed above the mounting base; a threaded rod, which is rotatably connected to the inside of the mounting base and is transmission-connected to the output end of the first motor; a threaded sleeve, which is threadedly arranged on the outside of the threaded rod; and a movable block, which is fixed on the outside of the threaded sleeve.

[0008] In a preferred embodiment of the pH meter cleaning and wiping mechanism of the present invention: the moving mechanism includes an electric push rod which is fixed to the outside of the movable block.

[0009] In a preferred embodiment of the pH meter cleaning and wiping mechanism of the present invention: the first cleaning unit includes a water tank, and an ultrasonic generator is integrated in the water tank to perform ultrasonic cleaning on the pH meter body device.

[0010] In a preferred embodiment of the pH meter cleaning and wiping mechanism of the present invention: the second cleaning unit includes a cleaning seat, a hook sticker is fixed on the inner side of the cleaning seat, and a water-absorbing sponge is fixed on the inner side of the hook sticker through a velvet sticker.

[0011] In order to solve the above technical problems, the present invention also provides the following technical solutions: a cleaning device, including a pH meter cleaning and wiping mechanism, and a support structure, which is arranged above the water tank; a power part, which is arranged inside the support structure; and a swinging part, which is connected to the power part and swings under the control of the power part to evenly spray the liquid.

[0012] In a preferred embodiment of the cleaning device of the present invention, the power component includes a second motor, an output end of which is connected to a worm.

[0013] In a preferred embodiment of the cleaning device of the present invention: the swing component includes a connecting shaft, which is vertically arranged below the worm and rotatably connected to the supporting structure; a worm wheel, which is fixed to the top of the connecting shaft and engages with the worm; a connecting frame, which is fixed to the top of the connecting shaft; an arc-shaped hollow plate, which is fixed on the connecting frame; and a nozzle, which is fixed to the outside of the arc-shaped hollow plate.

[0014] In a preferred embodiment of the cleaning device of the present invention, the nozzles are trumpet-shaped and are arranged at equal intervals below the arc-shaped hollow plate.

[0015] The beneficial effects of the present invention are: the vertical movement of the pH meter body device is achieved by driving the threaded rod and the threaded sleeve assembly by the first motor, combined with the rapid positioning of the electric push rod in the horizontal direction, ensuring that the instrument can accurately reach the designated position in three-dimensional space for cleaning work.

[0016] An ultrasonic generator is used to deeply clean the pH meter body, using the impact force of tiny bubbles generated by high-frequency vibration to remove stubborn stains while avoiding damage that may be caused by direct physical contact.

[0017] The second cleaning unit, which is a combination of a cleaning seat and a water-absorbing sponge, is used for surface wiping. The combination of hook stickers and suede stickers facilitates the replacement of the water-absorbing sponge, ensuring stability and efficiency during the wiping process.

[0024] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0025] Reference Figure 1-2 The present embodiment provides a pH meter cleaning and wiping mechanism, including an instrument body 1, a driving mechanism 2, used to drive the pH meter body device 111 to move in the vertical direction; a moving mechanism 3, connected to the driving mechanism 2, used to drive the pH meter body device 111 to move in the horizontal direction; a fixed clamping mechanism 4, arranged at the end of the moving mechanism 3, used to detachably fix the pH meter body device 111 to be cleaned; a cleaning component 5, including a first cleaning unit 51, used to achieve deep cleaning through non-contact energy transfer; a second cleaning unit 52, used to achieve surface wiping through physical contact.

[0026] In this embodiment, the driving mechanism 2 is used to drive the pH meter body 111 to move in the vertical direction. This component ensures that the pH meter body 111 can accurately reach the designated position for cleaning.

[0027] The moving mechanism 3 is connected to the driving mechanism 2 and is responsible for driving the pH meter body 111 to move horizontally. Combined with the driving mechanism 2, these two components together provide the ability to move in three-dimensional space.

[0028] The fixed clamping mechanism 4 is located at the end of the movable mechanism 3 and is used to removably secure the pH meter body 111 to be cleaned. It features a resilient clamping structure specifically designed to secure the pH meter body 111. This ensures that the instrument body 1 remains stably fixed during the cleaning and wiping process, preventing damage from vibration or movement and improving cleaning safety and efficiency.

[0029] The first cleaning unit 51 uses a non-contact energy transfer method to achieve deep cleaning. This method may involve using ultrasonic energy to remove stains in hard-to-reach areas without direct physical contact, reducing potential damage to sensitive components.

[0030] The second cleaning unit 52 wipes the surface by physical contact, which usually refers to directly wiping the instrument surface with cloth or other materials to remove water stains and other attachments.

[0031] refer to Figure 1-2In one embodiment provided herein, an instrument body 1 has a mounting base 11 fixed above it; a driving mechanism 2 includes a first motor fixed above the mounting base 11; a threaded rod 21 rotatably connected to the interior of the mounting base 11 and transmission-connected to the output end of the first motor; a threaded sleeve 22 disposed on the outside of the threaded rod 21; and a movable block 23 fixed to the outside of the threaded sleeve 22. The rotation of the threaded rod 21 is driven by the first motor, and the threaded sleeve 22 drives the movable block 23 to move axially along the threaded rod 21 through a threaded connection, thereby controlling the vertical position of the pH meter body 111. The motor-driven threaded transmission structure enables precise lifting and lowering control of the instrument body 1, ensuring the automation of the cleaning and wiping process. The moving mechanism 3 includes an electric push rod fixed to the outside of the movable block 23. The lateral drive of the electric push rod enables the pH meter body 111 to be quickly positioned on the cleaning seat 521, shortening the wiping time and improving operational efficiency. The first cleaning unit 51 includes a water tank 511, in which an ultrasonic generator is integrated for ultrasonically cleaning the pH meter main body 111. Through ultrasonic cleaning technology, stubborn stains on the surface of the pH meter main body 111 are effectively removed, and the cleaning effect is improved. The second cleaning unit 52 includes a cleaning seat 521, and a hook sticker is fixed on the inner side of the cleaning seat 521, and a water-absorbing sponge 522 is fixed on the inner side of the hook sticker through a velvet sticker; wherein, the pH meter main body 111 is connected to the electric push rod through a limit fixing frame, and is moved up and down by the rotation of the threaded rod 21 to realize the ultrasonic cleaning and water-absorbing sponge 522 wiping functions. Through the synergistic effect of the threaded transmission and the electric push rod, the lifting and lateral movement of the pH meter main body 111 is realized, and the combination of ultrasonic cleaning and water-absorbing sponge 522 wiping effectively improves the cleaning efficiency and wiping thoroughness.

[0032] In the present embodiment, the driving mechanism 2 includes components such as a first motor, a threaded rod 21, a threaded sleeve 22 and a movable block 23. The first motor is fixed above the mounting base 11 to provide a power source. The threaded rod 21 is rotatably connected to the inside of the mounting base 11 and is directly connected to the output end of the first motor so that the rotational motion of the first motor can be converted into the rotation of the threaded rod 21. The threaded sleeve 22 is arranged on the outside of the threaded rod 21 and converts the rotational motion of the threaded rod 21 into linear motion through the threaded engagement with the threaded rod 21. The movable block 23 is fixed on the threaded sleeve 22 and moves as the threaded sleeve 22 moves along the axial direction of the threaded rod 21. The movable block 23, i.e., the upper and lower positions of the pH meter body device 111, are controlled by the first motor to ensure the automation of the cleaning and wiping process.

[0033] Moving mechanism 3 primarily comprises an electric push rod, a component fixed to the outside of movable block 23. This push rod pushes or pulls pH meter body 111 horizontally, enabling it to quickly and accurately position itself on cleaning seat 521 for the next cleaning or wiping step. This significantly reduces the time required to switch from one operating point to another, improving overall operational efficiency.

[0034] The first cleaning unit 51 is a water tank 511 integrated with an ultrasonic generator. When the pH meter body 111 needs to be deeply cleaned, it is immersed in the water tank 511 filled with cleaning liquid. At this time, the ultrasonic generator is activated, generating high-frequency vibrations, forming countless tiny bubbles in the liquid. These bubbles quickly expand and burst, and the impact force generated can effectively remove stubborn stains attached to the surface of the pH meter body 111. Ultrasonic cleaning technology not only has a significant cleaning effect, but also can complete a comprehensive and thorough cleaning of complex-shaped objects such as the pH meter body 111 without damaging its sensitive components.

[0035] The second cleaning unit 52 is composed of a cleaning seat 521 and a hook sticker inside it. A water-absorbing sponge 522 is fixed to the inner side of the hook sticker via a velvet sticker. After the pH meter main unit 111 is ultrasonically cleaned, it will be moved to the cleaning seat 521 and wiped with a water-absorbing sponge 522 to achieve the purpose of drying. Here, the water-absorbing sponge 522 is fixed by a combination of a hook sticker and a velvet sticker, which is convenient for replacement and ensures that the water-absorbing sponge 522 will not fall off easily during the wiping process. The dryness of the surface of the pH meter main unit 111 is ensured, avoiding measurement errors or other problems caused by residual moisture.

[0036] During the entire cleaning and wiping process, the threaded rod 21 is driven to rotate by the first motor, driving the threaded sleeve 22 and the movable block 23 thereon to move up and down, so that the pH meter body device 111 can be accurately positioned in the water tank 511 to receive ultrasonic cleaning. Afterwards, the electric push rod comes into play and moves the pH meter body device 111 laterally to the position of the cleaning seat 521. The two cleaning seats 521 can be close to each other under the action of the driving mechanism. Here, the absorbent sponge 522 will carefully wipe the pH meter body device 111 after cleaning. Not only does it achieve effective cleaning and drying of the pH meter body device 111, but it also greatly improves work efficiency and reduces the need for manual intervention.

[0037] In order to solve the above technical problems, the present invention also provides the following technical solutions: a cleaning device, including a pH meter cleaning and wiping mechanism, and a support structure 6, arranged above the water tank 511; a power part 7, arranged inside the support structure 6; a swinging part 8, connected to the power part 7, and swinging under the control of the power part 7, for evenly spraying the liquid.

[0038] It should be noted that the vertical groove on the mounting seat 11 can be closed by the elastic layer, that is, when the threaded sleeve 22 moves, it will affect the internal air pressure. The interior of the cleaning seat 521 is hollow and connected to the internal space of the mounting seat 11. When the interior of the cleaning seat 521 is under negative pressure, the hook surface drives the water-absorbing sponge 522 to contract, and the water-absorbing sponge 522 is squeezed, thereby squeezing out excess water from itself to achieve continuous wiping.

[0039] In this embodiment, the support structure 6 provides a stable platform for installing and carrying other components. The support structure 6 is arranged above the water tank 511 to ensure that all operations are carried out in the water tank 511, thereby effectively utilizing space and ensuring the safety of the cleaning process.

[0040] The power member 7 is arranged inside the support structure 6. The power member 7 generates mechanical motion through the second motor to provide the necessary rotational force for the swing component 8.

[0041] The swing component 8 is directly connected to the power member 7. When the power member 7 is started, it will start to swing due to the rotational force of the power member 7. The main function of the swing component 8 is to achieve uniform diffusion of soft water during the swinging process.

[0042] refer to Figure 1 and Figure 3 In one embodiment provided herein, the power member 7, a second motor, has a worm 71 connected to its output end; the swing member 8, a connecting shaft 81, is vertically disposed below the worm 71 and rotatably connected to the support structure 6; a worm gear 82 is fixed to the outside of the connecting shaft 81 and meshes with the worm 71; a connecting frame 83 is fixed to the outside of the connecting shaft 81; an arc-shaped hollow plate 84 is fixed below the connecting frame 83; and a nozzle 85 is fixed below the arc-shaped hollow plate 84. The second motor drives the worm 71 to rotate, thereby driving the worm gear 82 and the connecting shaft 81 to rotate, thereby causing the connecting frame 83 and the nozzle 85 to swing, thereby achieving uniform diffusion and cleaning of the soft water. The nozzle 85 swings through the transmission of the worm gear 82 and the worm 71, causing the soft water to spread evenly and improving the scale cleaning efficiency.

[0043] In this embodiment, the second motor is the power source for the drive mechanism. The output of the second motor is directly connected to the worm 71. When the motor is started, the rotational force generated by the motor is transmitted outward through the worm 71. This effectively converts the motor's rotation into an operating speed suitable for the application, meeting the requirements of specific working conditions. Furthermore, because the motor's speed and direction can be precisely controlled, the oscillation frequency and angle of the spray nozzle 85 can be flexibly adjusted to achieve uniform distribution of soft water.

[0044] Worm 71 acts as an intermediate transmission element, connecting the second motor and worm gear 82. The combination of worm 71 and worm gear 82 provides a large reduction ratio, which means that even at low input speeds, high output torque can be achieved, thereby enhancing the load adaptability of the entire device.

[0045] The swinging member 8 primarily comprises a connecting shaft 81 and a worm gear 82, which cooperate to achieve effective swinging of the nozzle 85. The connecting shaft 81 is vertically disposed below the worm 71 and is rotationally connected to the support structure 6. This arrangement allows the connecting shaft 81 to rotate freely about its own axis under the drive of the worm 71.

[0046] The worm wheel 82 is fixed to the top of the connecting shaft 81 and is precisely meshed with the worm 71. When the second motor drives the worm 71 to rotate, the worm wheel 82 rotates accordingly, thereby driving the connecting shaft 81 to rotate together.

[0047] In actual operation, when the second motor is activated, worm 71 begins to rotate, meshing with worm gear 82 to transmit torque to connecting shaft 81. As connecting shaft 81 rotates, the connecting frame 83 and spray head 85 mounted on it also swing accordingly. The rotation of connecting shaft 81 ensures that spray head 85 moves along a pre-set trajectory, ensuring that soft water evenly covers the target area. Furthermore, by changing the motor speed or direction, the swing amplitude and speed of spray head 85 can be flexibly adjusted, further improving cleaning efficiency and quality.

[0048] The arc-shaped hollow plate 84 is fixed on the connecting frame 83 to provide a fixed installation platform for the nozzle 85, ensuring that the nozzle 85 can swing accurately along the predetermined path.

[0049] The internal structure of nozzle 85 typically includes multiple small nozzle holes. These nozzle holes are designed to form a fan-shaped stream of soft water when it flows out, thereby increasing the contact area between the soft water and the surface to be cleaned. In addition, the angle and flow rate of nozzle 85 can be adjusted according to actual needs to adapt to the cleaning requirements of surfaces of different materials and shapes.

[0050] In actual operation, when the second motor starts and drives the connecting shaft 81 to rotate through the worm 71 and worm gear 82, the connecting frame 83 and the arc-shaped hollow plate 84 on the connecting shaft 81 will swing accordingly, thereby driving the spray head 85 to swing regularly. During this process, soft water enters the spray head 85 through the pipe and is sprayed out at the appropriate time. The swinging of the spray head 85 can evenly distribute the soft water on the surface to be cleaned, avoiding the problem of insufficient cleaning in some areas that may occur with traditional cleaning methods.

[0051] refer to Figure 1 and Figure 3In some embodiments, the nozzles 85 are trumpet-shaped and are evenly spaced along the underside of the curved hollow plate 84. The trumpet-shaped nozzles 85 expand the spraying range, and the evenly spaced arrangement ensures uniform cleaning of all areas within the water tank 511. A soft water inlet channel is provided within the curved hollow plate 84, through which the nozzles 85 communicate with an external soft water supply system.

[0052] In this embodiment, the nozzles 85 are trumpet-shaped and are evenly spaced along the bottom of the curved hollow plate 84. This significantly expands the spraying range. The trumpet-shaped opening structure allows the water flow to be dispersed at a wider angle, thereby covering a larger area.

[0053] A soft water inlet channel is located within the curved hollow plate 84, connecting the nozzle 85 to an external soft water supply system, ensuring smooth water flow to the nozzle 85. Using soft water, rather than hard water, effectively prevents scale formation. Scale is formed by the precipitation of calcium and magnesium ions in water. These minerals gradually deposit on pipes and nozzles 85, obstructing or even completely interrupting water flow. By using soft water, this risk is significantly reduced, thereby extending the life of the equipment.

[0054] Secondly, soft water helps improve the effectiveness of detergents. Soft water contains no or only trace amounts of calcium and magnesium ions, allowing the active ingredients in detergents to act more directly on the surface being cleaned, without the additional expense of softening the water. This not only enhances cleaning power but also reduces detergent usage, achieving both environmental and economic benefits.

[0055] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
