Description

Technical Field

[0001] This utility model belongs to the field of liquid-free alarm technology, specifically, it relates to an intelligent liquid-free automatic alarm device. Background Technology

[0002] In the field of machining, cutting fluids are widely used for cooling, lubricating, cleaning, and rust prevention of cutting tools. To ensure the performance of cutting fluids, modern workshops generally use automatic fluid mixing systems, which automatically mix the cutting fluid concentrate with water in a certain proportion and deliver it to the machine tool. In this system, a stable supply of cutting fluid concentrate is a key prerequisite for ensuring the concentration of the mixture and thus ensuring machining quality and equipment safety.

[0003] A review of current market-ready automatic cutting fluid dispensing stations reveals that their fluid supply typically relies on stock solutions stored in drum containers. However, existing technologies generally lack dedicated devices for effectively and reliably monitoring the fluid level or quantity within these containers. This leads to a common production hazard: when the fluid is depleted, the dispensing system continues to operate, but in reality, it is supplying the machine tool with pure water or an ineffective liquid with extremely low concentration. This situation can trigger a series of serious consequences, including abnormal tool wear or breakage, batch scrapping of workpieces, and corrosion of precision components inside the machine tool due to loss of anti-corrosion lubrication, resulting in significant direct and indirect economic losses.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the problem of liquid shortage alarm technology, the basic concept of the technical solution adopted by this utility model is as follows:

A detection end is fixedly connected between the liquid inlet and the liquid outlet. The detection end is connected to a detection module via a circuit. The detection module is electrically connected to a signal processing module. The signal processing module is electrically connected to a buzzer and a control module.

[0007] In a preferred embodiment of this utility model, a power module is fixedly connected inside the outer shell. The power module is electrically connected to the detection module, the signal processing module, and the buzzer.

[0008] In a preferred embodiment of this utility model, the detection module, the signal processing module, and the buzzer are distributed within the power supply module, and the detection module, the signal processing module, and the buzzer are all fixedly connected to the inner wall of the power supply module.

[0009] In a preferred embodiment of this utility model, a back plate is connected to the back of the outer shell by fasteners, and the corners of the back plate are reserved for installation. The shell is installed by snap-fitting and fastener connection.

[0010] In a preferred embodiment of this utility model, the control module is equipped with a reset button, an alarm light, and an LCD screen, which displays flow data.

[0011] In a preferred embodiment of this utility model, a dual-control valve is fixedly connected to the original liquid discharge end via a pipe, the dual-control valve is connected to a preliminary mixing chamber via a pipe, and the other end of the preliminary mixing chamber is connected to a water inlet via a pipe.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] Please see Figure 1-5 An intelligent liquid-free automatic alarm includes a housing 1. A liquid inlet 13 is fixedly connected to the bottom of the housing 1. The liquid inlet 13 is connected to a liquid outlet 14 through a pipe. A detection end 23 is fixedly connected between the liquid inlet 13 and the liquid outlet 14. The detection end 23 is connected to a detection module 22 through a line. The detection module 22 is electrically connected to a signal processing module 24. The signal processing module 24 is electrically connected to a buzzer 25 and a control module 11.

[0027] During operation, the raw liquid is first introduced into the raw liquid inlet 13. During the supply of raw liquid, the flow rate is judged by the detection end 23. When the flow rate is normal, no reaction is made. When the flow rate decreases or disappears, the detection end 23 transmits the judged signal to the detection module 22 through an electrical connection. The detection module 22 transmits the signal to the signal processing module 24. After processing the signal, the signal processing module 24 activates the control module 11 and the buzzer 25. The control module 11 flashes the light, and the buzzer 25 sounds an alarm, thereby alerting the surrounding staff. The signal processing module 24 also transmits the signal to the data terminal, so it can serve as a warning even when no one is present, achieving a targeted effect.

[0028] It is worth noting that the detection end 23 includes: a flow sensor body; a water distributor fixing seat connected to the flow sensor body, the plane of the water distributor fixing seat being lower than the end face of the flow sensor body; a water distributor fixed on the water distributor fixing seat, a positioning shaft protruding from the water distributor; and an impeller connected to the water distributor, the impeller having a positioning hole, the bottom surface of the positioning hole contacting the top surface of the positioning shaft. The above-mentioned utility model can effectively prevent the parts inside the flow sensor from being disassembled during disassembly of the flow sensor, ensuring the installation quality of the parts and improving the stability of the flow sensor. The detection end 23 has already been disclosed in the prior art flow sensor CN206740185U, and will not be described in detail here.

[0029] The outer casing 1 is fixedly connected to a power module 2, which is electrically connected to a detection module 22, a signal processing module 24, and a buzzer 25. A plug module 21 is fixedly connected to the power module 2, which penetrates the outer casing 1. The detection module 22, the signal processing module 24, and the buzzer 25 are distributed within the power module 2, and all three are fixedly connected to the inner wall of the power module 2.

[0030] By plugging the plug module 21 into the socket to supply power, the power module 2 processes the incoming current, transforms the current into voltage, and supplies power to the detection module 22, signal processing module 24, and buzzer 25, achieving a plug-and-play effect. In addition, the power module 2 can store power to provide a working environment in the event of a power outage, achieving continuous power supply stability, and is suitable for monitoring the liquid-free state of containers in fixed locations.

[0031] The back of the outer shell 1 is connected to a back plate 12 by fasteners. The corners of the back plate 12 are reserved for installation, and the installation is carried out by snap-fit ​​and fastener connection.

[0032] The back plate 12 facilitates the installation of the outer casing 1 in a suitable working position. With the pre-reserved installation positions at the corners of the back plate 12, various installation methods can be achieved, such as snap-fit ​​or fastener connection, ensuring that the working position of the device is fixed and does not affect the operation.

[0033] The control module 11 integrates a reset button, an alarm light, and an LCD screen, which displays flow data.

[0034] The alarm light serves as a warning when there is no liquid and the surrounding environment is too noisy, and the reset button ensures that it can work normally after the fault is cleared.

[0035] The original liquid discharge end 14 is fixedly connected to a double control valve 4 via a pipe. The double control valve 4 is connected to a preliminary mixing chamber 41 via a pipe. The other end of the preliminary mixing chamber 41 is connected to a water inlet end 3 via a pipe. The bottom of the water inlet end 3 is fixedly connected to a multi-port water inlet 32. The upper end of the water inlet end 3 is fixedly connected to a pressure gauge 31.

[0036] The multi-channel water supply is achieved by setting multiple water inlets 32, and the water pressure is increased. The water pressure is monitored by setting pressure gauge 31. Water enters the preliminary mixing chamber 41 through the pipeline. The raw liquid discharge end 14 sends an appropriate amount of raw liquid into the preliminary mixing chamber 41 through the restriction of the dual control valve 4. The water pressure and the raw liquid are impacted and mixed to achieve the premixing step, which improves the subsequent mixing efficiency. The premixed liquid is discharged through the other end of the preliminary mixing chamber 41.

[0037] The initial mixing chamber 41 controls the amount of raw liquid entering and, based on the water pressure measured by the pressure gauge 31, determines the concentration ratio of the premixed liquid.

[0038] It is worth noting that the preliminary mixing chamber 41 includes a shell structure, a lower plate, an inlet regulating component, and an outlet regulating component. The shell structure includes an outer shell and a base; the lower plate is provided with an inlet channel and an outlet channel; the inlet regulating component includes an inlet knob and an inlet plate, with an inlet hole on the inlet plate; the outlet regulating component includes an outlet knob and an outlet plate, with a notch for water discharge. By simultaneously setting the inlet regulating component and the outlet regulating component inside the shell structure, rotating the inlet knob causes the inlet plate to rotate, adjusting the relative position between the inlet hole and the inlet channel to achieve inlet regulation; rotating the outlet knob causes the outlet plate to rotate, aligning the notch on the outlet plate with different outlet channels to achieve outlet regulation. The entire valve core structure is ingeniously and reasonably designed, small in size, space-saving, and easy to use. The preliminary mixing chamber 41 has already been disclosed in a dual-control valve core CN211082941U in the prior art, and will not be described in detail here.

[0039] Working Principle: During operation, the raw liquid is first introduced through the inlet 13. During the supply of raw liquid, the flow rate is determined by the detection end 23. When the flow rate is normal, no reaction is taken. When the flow rate decreases or disappears, the detection end 23 transmits the determined signal to the detection module 22 via an electrical connection. The detection module 22 then transmits the signal to the signal processing module 24. After processing the signal, the signal processing module 24 activates the control module 11 and the buzzer 25. The control module 11 flashes a light, and the buzzer 25 sounds an alarm. The system provides alerts to nearby staff, and the signal processing module 24 transmits the signal to the data terminal, serving as a warning even when no one is present. It achieves a targeted function by plugging the plug module 21 into the socket to supply power. The power module 2 then processes the incoming current, transforms it, and powers the detection module 22, signal processing module 24, and buzzer 25, achieving a plug-and-play effect. Furthermore, the power module 2 can store power, providing a working environment during power outages and ensuring continuous power supply stability, making it suitable for fixed locations. The container is equipped with a liquid-free state monitoring system. The backplate 12 facilitates the installation of the outer casing 1 in a suitable working position. The pre-reserved installation positions on the corners of the backplate 12 allow for various installation methods, such as snap-fit ​​or fastener connection, ensuring the device's working position is fixed and does not affect operation. An alarm light provides a warning in the event of liquid loss, especially in noisy surroundings. A reset button ensures normal operation after troubleshooting. Multiple water inlets 32 provide a multi-channel water supply and increase water pressure. A pressure gauge 31 monitors the water pressure. Water enters the preliminary mixing chamber 41 through a pipe. The raw liquid discharge end 14, controlled by a dual-control valve 4, delivers an appropriate amount of raw liquid into the preliminary mixing chamber 41. The water pressure and the raw liquid undergo impact mixing, achieving a pre-mixing step and improving subsequent mixing efficiency. The pre-mixed liquid is discharged through the other end of the preliminary mixing chamber 41. The preliminary mixing chamber 41 controls the amount of raw liquid entering and adjusts the concentration ratio of the pre-mixed liquid based on the water pressure measured by the pressure gauge 31.
