Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a detonation silencing mechanism for a pulse detonation water purification device. Background Technology

[0002] A water purifier is a household or commercial appliance used to improve water quality. Its main function is to remove harmful substances from water through physical, chemical, or biological methods, providing safe and clean drinking water. With increasing environmental pollution and growing health awareness, water purifiers have become an essential appliance in many households.

[0003] Compared to existing water purifiers, those employing pulse detonation technology can instantly break down the cell membranes of bacteria and viruses through a pulsed electric field (PEF) or high-voltage pulses, achieving an inactivation rate of up to 99.9%. This avoids the chemical residue problems associated with traditional chlorine disinfection and is highly effective against drug-resistant bacteria (such as Legionella) and difficult-to-treat microorganisms like algal spores. It achieves highly efficient sterilization and inactivation of microorganisms and reduces reliance on filter cartridges, as pretreatment degrades contaminants, eliminating the need for filter replacement. However, the purification process can generate some noise, requiring noise reduction. Therefore, we propose a detonation noise reduction mechanism for a pulse detonation water purification device.

[0006] To further elaborate, the mounting groove in the pulse detonation chamber is provided with a latching part, which can be used to fasten the groove edge of the main housing to prevent the silencing component from falling off the mounting groove.

[0007] To elaborate further, the main box has a handle on the front side and a storage slot for inserting the sound-absorbing plate assembly on the rear side.

Detailed Implementation

[0016] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Specific Implementation Example 1: Combined with Appendix Figure 1 To be continued Figure 4As shown, a pulse detonation water purification device includes a detonation silencing mechanism comprising a pulse detonation chamber 10. Each pulse transmitter 20 within the pulse detonation chamber 10 is equipped with a pulse emission tube 21, and the pulse emission tube 21 of each pulse transmitter 20 is connected to an energy-concentrating ring 30. Several mounting slots 11 are provided within the pulse detonation chamber 10, and the pulse transmitters 20 are positioned within these slots. A silencing component 40 is snapped into each mounting slot 11, positioned above the pulse transmitters 20. The silencing component 40 includes a main housing 41, into which several sets of silencing plates are inserted. Each silencing plate set includes a ceramic fiber board 401, a polyurethane foam board 402, and a volcanic rock board 403, with the polyurethane foam board 402 sandwiched between the ceramic fiber board 401 and the volcanic rock board 403. The ceramic fiber board 401 is resistant to high temperatures, water, and corrosion. The polyurethane foam board 402 has a closed-cell structure, is waterproof, does not absorb water during long-term immersion, and exhibits high stability. The porous structure of volcanic rock slab 403 is stable, allowing water to flow through while dissipating sound energy. Noise enters the internal pores of ceramic fiber board 401, polyurethane foam board 402, and volcanic rock slab 403, where it is converted into heat energy through friction with the pore walls, thus achieving sound absorption.

[0018] The pulse transmitter 20 contains a pulse detonation assembly, which includes a pulse group and a detonation group. The pulse group includes a pulse generator, a power amplifier, and a pulse power supply. The pulse power supply is connected to the input terminal of the pulse generator, and the output terminal of the pulse generator is connected to the input terminal of the power amplifier. The output terminal of the power amplifier is equipped with a pulse transmitting tube. The detonation group includes an electric detonator and a detonation power supply for powering the electric detonator. The input terminal of the electric detonator is connected to the output terminal of the detonation power supply, and the output terminal of the electric detonator is equipped with a detonation guide tube.

[0019] Specific Implementation Example 2: Combined with Appendix Figure 1 To be continued Figure 4 As shown, a pulse detonation water purification device includes a pulse detonation chamber 10. Each pulse transmitter 20 in the pulse detonation chamber 10 is provided with a pulse emission tube 21. The pulse emission tube 21 of each pulse transmitter 20 is connected to the energy focusing ring 30. Several mounting slots 11 are opened in the pulse detonation chamber 10. The pulse transmitter 20 is placed in the mounting slot 11. A silencing component 40 is snapped into the mounting slot 11. There are eight mounting slots 11 in total, which are distributed in a circular array at equal intervals on the inner wall of the pulse detonation chamber 10. A silencing component 40 is correspondingly provided at each mounting slot 11.

[0020] The silencing component 40 is located above the pulse transmitter 20. The silencing component 40 includes a main housing 41, into which several sets of silencing panels are inserted. Each silencing panel set includes a ceramic fiber board 401, a polyurethane foam board 402, and a volcanic rock board 403, with the polyurethane foam board 402 sandwiched between the ceramic fiber board 401 and the volcanic rock board 403. The ceramic fiber board 401 is resistant to high temperatures, water, and corrosion. The polyurethane foam board 402 has a closed-cell structure, making it waterproof and non-absorbent even after long-term immersion, exhibiting high stability. The volcanic rock board 403 has a porous structure, ensuring stability; water can pass through, but sound energy is dissipated.

[0021] Combined with appendix Figure 1 and attached Figure 2 As shown, a latching part 12 is provided at the mounting groove 11 inside the pulse detonation chamber 10. The latching part 12 can be used to lock the groove edge 411 of the main housing 41 to prevent the silencing assembly 40 from falling off from the mounting groove 11. The main housing 41 is made of aluminum silicate ceramic fiber. A handle 412 is provided on the front side of the main housing 41, and a storage groove 413 for inserting the silencing plate assembly is provided on the rear side of the main housing 41. Limiting edges 414 are provided on both the left and right sides of the storage groove 413. (See attached...) Figure 1 As shown, by holding handle 412, the entire silencing assembly 40 can be removed from the mounting slot 11 of the pulse detonation chamber 10, making it convenient to replace the silencing materials such as ceramic fiber board 401, polyurethane foam board 402, and volcanic rock board 403 of the silencing assembly 40.

[0022] This invention employs a silencing component 40 structure design within the pulse detonation chamber. The silencing component contains multiple sets of silencing plates, which can absorb noise from all directions within the pulse detonation chamber, thereby achieving silencing.
