Description

Technical Field

[0001] This utility model relates to the field of fluid filtration and monitoring technology, and in particular to a filter element blockage alarm indication structure. Background Technology

[0002] In liquid or gas filtration systems, filter cartridges are core consumables whose main function is to intercept particulate impurities, contaminants, or microorganisms in the fluid to ensure the quality of water or gas output from downstream equipment. Over time, the surface and internal pores of the filter cartridge gradually become clogged with contaminants, leading to increased flow resistance, decreased flow rate, and increased pressure drop. Failure to replace the cartridge in a timely manner will not only reduce system efficiency but may also cause equipment overheating, increased energy consumption, and even serious consequences such as filter cartridge damage and contaminant penetration.

[0003] Currently, most household or small-to-medium-sized industrial filtration equipment still relies on fixed replacement cycles or user subjective judgment to determine when to replace filter cartridges. This lack of an objective, real-time feedback mechanism for clogging status leads to waste from premature replacement or system malfunctions from delayed replacement. Furthermore, existing alarm devices often have low integration with the filter housing, resulting in complex installation requiring additional openings and wiring, increasing manufacturing and maintenance difficulties.

[0004] Therefore, a filter clogging alarm indicator structure needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of lacking a real-time clogging status feedback mechanism and low integration with the filter housing, this utility model provides a filter cartridge clogging alarm indication structure.

An inlet pipe is located on the right side of the filter cartridge housing. A support plate is fixedly connected to the lower inner side of the filter cartridge housing. A threaded rod is fixedly connected to the top of the support plate. A first threaded cap is threaded onto the threaded rod. A support tube is fixedly connected to the top of the first threaded cap. A filter cartridge screen is fitted onto the support tube. Multiple inlets are provided on the support tube. A second threaded cap is threadedly connected to the upper outer side of the filter cartridge housing. A connecting pipe is fixedly connected to the bottom inner side of the second threaded cap, and the inner side of the connecting pipe is in close contact with the upper outer side of the support tube. An outlet pipe is fixedly connected to the upper inner side of the second threaded cap. An alarm light is installed on the right side of the second threaded cap. A sensor is located at the lower left end of the alarm light, inside the outlet pipe. A control module is located inside the second threaded cap. Both the sensor and the alarm light are electrically connected to the control module.

[0007] As an improvement to the above solution, it also includes a first threaded interface, with the first threaded interface fixedly sleeved on the right side of the water inlet pipe.

[0008] As an improvement to the above solution, a sealing strip is also included, with the upper part of the support tube fixedly fitted with the sealing strip.

[0009] As an improvement to the above solution, a second threaded interface is also included, with the upper part of the water outlet pipe fixedly fitted with the second threaded interface.

[0010] As an improvement to the above solution, it also includes an alarm and a dustproof net. An alarm is installed on the right side of the second threaded cap, and a dustproof net is installed on the top of the alarm. The alarm is electrically connected to the control module.

[0011] As an improvement to the above solution, it also includes an energy storage battery and a charging interface. The energy storage battery is installed on the left side of the second threaded cap, and a charging interface is provided on the front side of the top of the second threaded cap. The charging interface is electrically connected to the energy storage battery. The sensor, alarm light, alarm and control module are all electrically connected to the energy storage battery, and the energy storage battery supplies power to the sensor, alarm light, alarm and control module.

[0012] The beneficial effects of this utility model are as follows: 1. By setting a sensor in the water outlet pipe and cooperating with the control module in the second threaded cap, this utility model can realize real-time monitoring and automatic judgment of the filter element blockage status, which effectively solves the problem of waste caused by premature replacement or system failure caused by late replacement due to the reliance on fixed cycle replacement or subjective experience judgment of traditional filter elements. In addition, the quick-release threaded connection between the second threaded cap and the filter element shell facilitates filter element replacement and improves maintenance efficiency. Furthermore, a sealing strip is provided between the support tube and the connecting tube to ensure filtration integrity.

[0013] 2. This utility model uses the combination of alarm light and alarm to simultaneously issue visual and audible prompts when the filter element is clogged to a preset threshold, ensuring that users are informed of the replacement need in a timely manner. Furthermore, by setting a dustproof net, it effectively prevents dust and moisture from entering the alarm, ensuring long-term stable operation. In addition, with the built-in energy storage battery and charging interface, it can operate independently without an external power source. Attached Figure Description

Detailed Implementation

[0020] Example: A filter cartridge clogging alarm indicator structure, such as Figures 1-5 As shown, the system includes a filter cartridge housing 1, an inlet pipe 12, a support plate 2, a threaded rod 21, a first threaded cap 32, a support tube 31, a filter element screen 3, a second threaded cap 4, a connecting pipe 41, an outlet pipe 42, an alarm light 51, and a sensor 5. The inlet pipe 12 is located on the right side of the filter cartridge housing 1. A support plate 2 is welded to the lower inner side of the filter cartridge housing 1. A threaded rod 21 is fixedly connected to the top of the support plate 2. A first threaded cap 32 is threaded onto the threaded rod 21. A support tube 31 is fixedly connected to the top of the first threaded cap 32. A filter element screen 3 is fitted onto the support tube 31. The filter cartridge housing 1 has multiple water inlets 33. The outer side of the upper part of the filter cartridge housing 1 is threaded with a second threaded cap 4. The bottom of the inner side of the second threaded cap 4 is fixedly connected with a connecting pipe 41. The inner side of the connecting pipe 41 is in close contact with the outer side of the upper part of the support pipe 31. The upper part of the inner side of the second threaded cap 4 is fixedly connected with a water outlet pipe 42. An alarm light 51 is installed on the right side of the second threaded cap 4. A sensor 5 is set at the lower left end of the alarm light 51, and the sensor 5 is located inside the water outlet pipe 42. A control module is set inside the second threaded cap 4. The control module contains a microcontroller development board, model Arduino Mega 2560. The sensor 5 and the alarm light 51 are both electrically connected to the control module.

[0021] like Figure 1 and Figure 2 As shown, it also includes a first threaded interface 11, and the first threaded interface 11 is fixedly sleeved on the right side of the water inlet pipe 12.

[0022] like Figure 4 As shown, it also includes a sealing strip 34, which is fixedly sleeved on the upper part of the support tube 31.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a second threaded interface 43, and the upper part of the water outlet pipe 42 is fixedly sleeved with the second threaded interface 43.

[0024] like Figure 1 and Figure 5 As shown, it also includes an alarm 52 and a dustproof net 53. The alarm 52 is installed on the right side of the second threaded cap 4, and the dustproof net 53 is provided on the top of the alarm 52. The alarm 52 is electrically connected to the control module.

[0025] like Figure 1 and Figure 5 As shown, it also includes an energy storage battery 54 and a charging interface 55. The energy storage battery 54 is installed on the left side of the second threaded cap 4, and the charging interface 55 is provided on the front side of the top of the second threaded cap 4. The charging interface 55 is electrically connected to the energy storage battery 54. The sensor 5, the alarm light 51, the alarm 52 and the control module are all electrically connected to the energy storage battery 54, and the energy storage battery 54 supplies power to the sensor 5, the alarm light 51, the alarm 52 and the control module.

[0026] When this device is needed to prevent the filter element from being clogged for too long, it is first connected to the external pipeline through the first threaded interface 11 and the output system through the second threaded interface 43. After the fluid passes through the support plate 2, it passes through the filter element screen 3 and comes to the support pipe 31 to intercept impurities. Then, it enters the interior of the support pipe 31 through the multiple inlets 33 opened on the side wall of the support pipe 31. The filtered clean fluid flows upward along the inner wall of the support pipe 31 and finally enters the outlet pipe 42 through the connector 41 and is output to the downstream system through the second threaded interface 43.

[0027] Under normal use, the filter element and screen 3 are unobstructed, the fluid resistance is small, the flow rate inside the outlet pipe 42 is stable, and the pressure is normal. At this time, the control module inside the second threaded cap 4 activates the sensor 5 installed inside the outlet pipe 42 to detect the flow rate in the pipe in real time, and then transmits the data to the control module. As the usage time increases, the filter element and screen 3 are gradually blocked by contaminants, the flow cross section decreases, and the flow rate decreases. When the detected value is lower than the preset threshold, the control module judges that the filter element is blocked, controls the alarm light 51 to light up, and drives the alarm 52 to emit an audible alarm to enhance the reminder effect.

[0028] The alarm 52 is equipped with a dustproof net 53 on top to prevent dust from entering and affecting the sound-emitting unit. The entire electronic system is powered by a built-in energy storage battery 54 and can be charged or updated via a charging interface 55. No external power supply is required, making it easy to install in environments without electricity.

[0029] In addition, a sealing strip 34 is provided on the upper part of the support tube 31 to ensure tight contact between the connecting tube 41 and the support tube 31, preventing short-circuit leakage of unfiltered fluid. The second threaded cap 4 is connected to the filter element housing 1 by threads and can be disassembled by twisting the second threaded cap 4, which facilitates cleaning or replacement of the filter element screen 3.

[0030] When the user replaces the filter element 3, the sensor 5 transmits the detected flow data to the control module. The control module determines that the flow value has returned to the normal range and controls the alarm light 51 to turn off and the alarm 52 to stop.
