Technical Field
[0001] This invention belongs to the technical field of architectural engineering surveying tools, specifically relating to a magnetic electronic level. Background Technology
[0002] A spirit level is an important measuring tool for ensuring flatness, verticality, and levelness in construction and decoration. Traditional spirit levels often use a "bubble bubble + scale" observation structure, which uses the position of the bubble inside the leveling bubble under the influence of gravity to indicate the tilt of the measured surface. However, this traditional solution has two main drawbacks in practical applications: First, in dimly lit environments (such as interior ceiling decoration or pipe shaft work), the slight displacement of the bubble is difficult to clearly identify, affecting construction progress and quality; second, bubble level can only "infer" the tilt trend from the relative position of the bubble and the scale lines, but cannot intuitively and instantly provide feedback on the specific tilt direction (such as left or right), resulting in low calibration efficiency for tasks requiring rapid and precise adjustments.
[0003] To address the aforementioned issues, some electronic levels have emerged in the market. These typically incorporate tilt sensors and digital displays, allowing direct reading of angles or deviations, thus mitigating reading difficulties and accuracy problems to some extent. However, while these existing electronic levels offer numerical accuracy, users still need to read and understand the numbers or arrows on the screen when quickly determining approximate direction and status. This is less intuitive and efficient when holding objects or in fast-paced assembly line operations. Furthermore, when working on metal structures, existing tools often require handheld fixation and visual observation, leaving room for improvement in ease of operation. Therefore, the market urgently needs a new type of measuring tool that integrates precise digital display, intuitive direction indication, and magnetic fixation to comprehensively overcome the shortcomings of traditional and existing technologies. Summary of the Invention
[0004] The problem this invention aims to solve is the technical deficiencies of existing horizontal measuring tools in terms of intuitive direction indication, adaptability to low-light environments, and ease of operation on metal surfaces.
[0005] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A magnetic electronic level includes a level body and a magnetic fixing structure, wherein the magnetic fixing structure is disposed on the level body for attaching the level to a metal working surface; and further includes: A multi-directional sensing component, disposed inside the ruler body, includes a first sensing component and a second sensing component. Each of the first and second sensing components includes a tubular container containing a positive electrode and a negative electrode, and is filled with a conductive electrolyte solution. The first sensing component is connected to a battery via a first conductive circuit, and the second sensing component is connected to the battery via a second conductive circuit. In each container, when the conductive electrolyte solution simultaneously immerses both the positive and negative electrodes, the corresponding conductive circuit is activated. The indicator component is a light-emitting element, fixed to the ruler body, and connected to the first conductive circuit and the second conductive circuit respectively; An inclinometer and a digital display screen, wherein the digital display screen is electrically connected to the inclinometer and is used to display the measurement data of the inclinometer.
[0006] As a preferred option, a further technical solution to the above structure is: The first sensing component is located at the middle position of the ruler body, and its positive electrode and negative electrode are respectively located at both ends of the container.
[0007] The beneficial effects obtained from the above features are as follows: This configuration is used to detect the tilt of the horizontal plane. When the level is completely horizontal, the liquid level of the conductive electrolyte solution in the middle container is horizontal, and the positive and negative electrodes at both ends are immersed, thus completing the circuit and illuminating the light-emitting element that indicates the level, providing an accurate horizontal reference indication.
[0008] There are two second sensing components, symmetrically arranged at both ends of the ruler. The positive and negative electrodes of the second sensing component located at the left end of the ruler are located on both sides of the left end of the container, and the positive and negative electrodes of the second sensing component located at the right end of the ruler are located on both sides of the right end of the container.
[0009] The beneficial effects obtained from the above features are as follows: This configuration is used to detect the tilt direction of a vertical plane. When the level is close to the vertical plane and in a completely vertical state, the solutions in the two end containers simultaneously immerse the positive and negative electrodes near their respective ends. Both circuits are connected, and the light-emitting elements in both directions are lit, providing a direct indication of the vertical state. If the plane tilts to the left, the electrode in the left end container is disconnected, and only the electrode in the right end container remains immersed. Only the light-emitting element in the corresponding direction is lit, thus providing a direct and immediate feedback on the tilt direction.
[0010] The tilt sensor and digital display are assembled with the second sensing component, and both the tilt sensor and digital display are electrically connected to the corresponding second conductive circuit.
[0011] The beneficial effects of these features include: linking precise digital display with intuitive direction indication; power is only supplied to the tilt sensor and digital display when the level is vertical, i.e., when any circuit of the second sensing component is active, to display the precise angle or deviation value. This not only saves energy but also directs the user's attention to the currently effective measurement dimension.
[0012] The container is a highly transparent or semi-transparent acrylic cylindrical tube, and the conductive electrolyte solutions of the first sensing component and the second sensing component are of different colors; the positive electrode and the negative electrode are copper conductive electrodes.
[0013] The beneficial effects of the above features are: different colored solutions allow users to quickly distinguish different sensing components visually, while retaining the traditional method of visually observing the solution position as an auxiliary method of judgment. Copper electrodes possess excellent conductivity and corrosion resistance, ensuring the reliability of circuit continuity.
[0014] The battery is installed inside the ruler body; the first conductive circuit and each of the second conductive circuits are connected in parallel.
[0015] The beneficial effects obtained from the above features are: the built-in battery makes the level a standalone tool that does not require an external power source, improving portability and applicability; the parallel circuit ensures that each sensing component works independently without interfering with each other, and the corresponding light-emitting element can be lit up when any circuit is turned on.
[0016] The digital display screen integrates a backlight module, forming a backlit display screen.
[0017] The beneficial effects obtained from the above features are: the backlight module makes the digital readings clearly visible even in dim or even completely dark environments, greatly improving the applicability of the tool in low-light operation scenarios such as inside ceilings and pipe shafts.
[0018] It also includes a control unit, which is electrically connected to the tilt sensor, the digital display screen and a voice broadcast module, and is used to drive the voice broadcast module to perform voice broadcast based on the measurement data of the tilt sensor.
[0019] The beneficial effects obtained from the above features are as follows: After adding the voice broadcast function, the operator can obtain the measurement data without looking at the level, realizing "auditory calibration". This has significant advantages in situations where the screen or light-emitting elements cannot be directly observed (such as when the line of sight is obstructed or the distance is far), further freeing up the eyes and improving work efficiency.
[0020] The containers of the first and second sensing components are respectively installed in the grooves cut into the surface of the ruler, and a transparent cover is provided on the top of the groove.
[0021] The beneficial effects obtained from the above features are: embedding the container in the groove and protecting it with a transparent cover can protect the fragile tubular container from direct impact, without affecting the user's observation of the solution state and light transmission effect, while also helping to keep the ruler surface flat and beautiful.
[0022] Compared with the prior art, the present invention employing the above structure has the following advantages: 1) This invention replaces traditional bubbles with a conductive electrolyte solution and combines an electrode and a light-emitting element to form a circuit, directly converting horizontal or tilted states into light signals. When the level is horizontal or vertical, the corresponding circuit is activated, and the light-emitting element lights up, providing a more intuitive and faster direction indication than reading bubbles or numbers, especially suitable for fast-moving assembly line operations. At the same time, the integrated tilt sensor and digital display screen can provide accurate numerical readings to meet the requirements of high-precision measurement. The magnetic fixing structure can attach the level to the metal working surface, freeing the operator's hands and significantly improving the convenience of working on metal surfaces such as steel structures. The light-emitting element and the backlit digital display screen together solve the problem of use in low-light environments. Attached Figure Description

[0025] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0026] See Figures 1 to 4 The present invention provides a magnetic electronic level, which mainly includes a level body 1, a magnetic fixing structure 2, a multi-directional sensing component, a prompting component 6, an tilt sensor 7, and a digital display screen 8.
[0027] The magnetic fixing structure 2, located on the ruler body 1, consists of multiple strongly magnetic neodymium iron boron patches embedded in the surface of the ruler body 1. These patches are used to securely attach the entire level to metal working surfaces such as steel pipes and steel beams. A battery 3 is installed inside the ruler body 1 to power the entire system.
[0028] A multi-directional sensing component is disposed inside the ruler body 1. The first sensing component 4 and the second sensing component 5 each include a highly transparent or semi-transparent tubular container 403. The container 403 is filled with a conductive electrolyte solution 404. A positive electrode 401 and a negative electrode 402 are disposed inside the container 403. The first sensing component 4 is connected to the battery 3 through a first conductive circuit, and the second sensing component 5 is connected to the battery 3 through a second conductive circuit. In each container 403, when the conductive electrolyte solution 404 simultaneously immerses both the positive electrode 401 and the negative electrode 402, the corresponding conductive circuit is activated. The positive electrode 401 and the negative electrode 402 are made of copper conductive electrodes. The solution of the first sensing component 4 can be green, and the solution of the second sensing component 5 can be red for differentiation. When the posture of the level ruler causes the solution surface in a certain container 403 to simultaneously immerse its positive electrode 401 and negative electrode 402, that circuit is activated.
[0029] The indicator component 6 consists of multiple light-emitting elements (LEDs), fixed to the surface of the ruler 1, and connected in series in the first conductive circuit and two second conductive circuits. When the circuit is connected, the corresponding LED is lit.
[0030] The tilt sensor 7 and the digital display screen 8 constitute a precision measurement and display system. The digital display screen 8 has a backlight module, and both are electrically connected to the conductive circuit of the second sensing component 5. The system is powered on and operates only when one of the second conductive circuits is open, displaying the current precise angle or deviation value.
[0031] Embodiment 1 of the present invention: This embodiment provides a basic configuration of a magnetic electronic level. The first sensing component 4 is located in the middle of the level body, with its tubular container 403 arranged horizontally and positive and negative electrodes 402 located at the left and right ends, respectively. This structure is used to detect levelness. When the level is placed horizontally, the conductive electrolyte solution 404 immerses the electrodes at both ends, and the green level indicator light illuminates.
[0032] Two second sensing components 5 are symmetrically arranged at the left and right ends of the ruler body, with their tubular containers 403 arranged horizontally. The positive electrode 401 and negative electrode 402 of the container 403 at the left end of the ruler body 1 are located on both sides of the left end of the container 403, and the positive electrode 401 and negative electrode 402 of the container 403 at the right end of the ruler body 1 are located on both sides of the right end of the container 403. When the horizontal ruler tilts to the left, the conductive electrolyte solution 404 in the container 403 concentrates to the left, immersing the positive electrode 401 and negative electrode 402 at the left end of the ruler body 1, and its red indicator light illuminates. Similarly, if the ruler body 1 is actually tilted to the right, the second conductive circuit at the right end of the ruler body 1 will be activated, and the red indicator light at the right end will illuminate, visually indicating the tilt state and direction of the ruler body.
[0033] Embodiment 2 of the present invention: Unlike Embodiment 1, in this embodiment, the second sensing component 5 is a relatively long tubular container 403 that extends from the left end to the right end of the ruler 1. The left and right ends are each connected to a second conductive circuit. The amount of conductive electrolyte solution 404 filled inside the container 403 is only sufficient to simultaneously connect one end of the conductive circuit. When the ruler 1 tilts to the left, all the conductive electrolyte solution 404 in the container 403 of the second sensing component 5 flows to the left end, making the second conductive circuit on the left end conductive. When the ruler 1 tilts to the right, all the conductive electrolyte solution 404 in the container 403 of the second sensing component 5 flows to the right end, making the second conductive circuit on the right end conductive.
[0034] The ruler body 1 is equipped with an independent power supply; the electrodes in each container 403, the power supply, and the corresponding light-emitting unit are connected in series to form an independent circuit loop, and the circuit loops are connected in parallel. The battery 3 is installed inside the ruler body 1; the first conductive circuit and each of the second conductive circuits are connected in parallel.
[0035] Based on the above structure, improvements are made to the power supply and control method of this solution: the tilt sensor 7 and digital display screen 8 are assembled with the second sensing component 5, and the tilt sensor 7 and digital display screen 8 are electrically connected to the corresponding second conductive circuit. In this embodiment, the power supply circuit of the tilt sensor 7 is linked with two second conductive circuits. When one of the second conductive circuits is turned on, the tilt sensor 7 and digital display screen 8 in that circuit are powered on and start measuring and displaying. In this way, when the operator uses a spirit level to check the verticality, he can not only judge whether there is tilt by the color of the light, but also directly understand the tilt direction by the position of the light and read the tilt degree through the screen.
[0036] Furthermore, it also includes a control unit, which is electrically connected to the tilt sensor 7, the digital display screen 8, and a voice broadcast module. The control unit is used to drive the voice broadcast module to perform voice broadcasts based on the measurement data from the tilt sensor 7. When the measured value stabilizes or reaches a preset angle (e.g., 0°, 90°), the voice broadcast module is driven to issue a voice prompt indicating "horizontal," "vertical," or a specific angle.
[0037] In order to protect the internal tubular container 403 and keep the appearance clean, a groove 101 is provided on the outer shell at the position corresponding to each container 403, the container 403 is embedded therein, and the top of the groove 101 is covered with a transparent acrylic or PC cover plate 9.
[0038] Optionally, the container 403 is a highly transparent or semi-transparent acrylic cylindrical tube, the conductive electrolyte solution 404 of the first sensing component 4 is green, and the conductive electrolyte solution 404 of the second sensing component 5 is red. The ruler body 1 has an IP protection rating to achieve waterproof and dustproof protection.
[0039] The length of the level ruler of this invention is less than or equal to 10cm, forming a mini electronic level ruler for slope detection in confined spaces.
[0040] The above solution will be explained in detail below with specific operational examples: Project Example 1: Construction of Decorative Wall and Floor Tiles After marking the lines for positioning, lay the first tile as a reference. Attach the electronic level of this invention to the tile surface (horizontal direction) and side (vertical direction) using a magnetic attachment or directly against the tile. Observe whether the green LED light in the horizontal direction is lit to ensure the reference tile is level and not tilted; simultaneously observe the vertical direction to ensure verticality. The screen can display extremely small deviations, ensuring absolute accuracy of the reference. During subsequent tiling, place the level across the joints of adjacent tiles. By observing the color of the LED light and the screen reading, it is possible to determine in one step whether the height difference between the two tiles is ≤0.5mm, which is far more efficient than traditional methods.
[0041] Project Example 2: Equipment Installation and Pipeline Construction During the installation of water supply and drainage pipes, magnetically attach or place this spirit level on the pipe surface, and adjust the pipe support until the display is level and the screen deviation value is ≤2mm / m. When installing cable trays and concealed electrical conduits, especially in poorly lit ceilings, the spirit level's backlit screen and LED light offer significant advantages, allowing for clear viewing of the level (within ±3mm / m) and slope without additional lighting, ensuring smooth wiring.
[0042] Project Example 3: Curtain Wall Construction During the glass curtain wall keel installation phase, workers can attach this spirit level to the steel columns and adjust them until the LED lights and screens both indicate verticality, allowing one person to complete the calibration independently. Before glass installation, the spirit level is used to quickly check the horizontality of the beams and the flatness of the overall keel surface, effectively avoiding the risk of cracking or uneven gaps caused by uneven stress after glass installation.
[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
