Definitions
- the invention relates to the shell structure of air pumps and particularly to air pumps that have a double shell structure for reducing noise leakage during operation.
- Conventional shell structure for air pumps generally includes a shell 2 consisting of an upper lid 21 and a base 22 .
- the shell 2 has a hollow housing chamber 20 located inside for installing the body 1 of an air pump.
- air pump body 1 When the air pump body 1 operates, air is discharged through an air duct 11 into an aquarium for use.
- Such a structure generates a greater noise when the air pump body 1 operates. It becomes an annoyance in house environments. While breeding pet fish can enhance environmental aesthetics and provide visual amusement, the generated noise spoils house serenity.
- the object of the invention is to provide a double shell structure for air pumps to reduce the noise leakage during air pump operation.
- the double shell structure of the invention mainly has an inner shell housed in an outer shell.
- the air pump body is installed in the inner shell.
- FIG. 1 is a sectional view of a conventional air pump.
- FIG. 2 is an exploded view of the invention.
- FIG. 3 is a sectional view of the invention.
- FIG. 4 is a sectional view of another embodiment of the invention.
- the invention mainly includes an outer shell 31 and an inner shell 32 located in the outer shell.
- the outer shell 31 and the inner shell 32 are interposed by a hollow space 310 .
- the inner shell 32 has a hollow housing chamber 320 for installing an air pump body 4 .
- the outer shell 31 consists of an outer upper lid 311 and an outer base 312 coupling together.
- the outer base 312 has a top edge forming an indented coupling rim 3124 .
- a sealing gasket 34 is mounted on the coupling rim 3124 to couple with another coupling rim 3112 formed on the inner side of the bottom edge of the outer upper lid 311 to form a seal to enhance noise insulation effect.
- the outer upper lid 311 further has at lest one semi-circular opening 3111 on the lateral side corresponding to at least one semi-circular opening 3122 on the outer base 312 to form at least one air discharge anchor hole A (the number of the hole depends on the number of air discharge ducts of the air pump body 4 ).
- the inner shell 32 has an inner base 322 to couple with an inner upper lid 321 .
- the inner base 322 has a hollow chamber 320 for installing the air pump body 4 , and one lateral side having at least one notch 3221 to enable an air discharge duct 41 to run through to connect to an elbow duct 42 .
- the elbow duct 42 has another end connecting to another air discharge duct 43 which couples with a duct sleeve 44 for discharging air.
- the inner upper lid 321 has a downward recess with a lid peripheral rim 3214 slightly larger than the outer peripheral rim of the inner base 322 .
- the inner upper lid 321 further has an opening 3211 to allow an air inlet duct 35 to run through.
- the air inlet duct 35 has a lower section 351 running through the inner side of the inner upper lid 321 to couple with an opening 361 of a thin sheet 36 (which serves to eliminate transmission of resonance and reduce noise generation) and an opening 331 of a soft pad 33 such that the soft pad 33 may be in contact with the top rim of the inner base 322 .
- the inner upper lid 321 may be closed and fastened through engaging screws 3213 into the apertures 3212 and 332 of the inner upper lid 321 and the soft pad 33 and the screw holes 3222 of the inner base 322 , thereby to fasten the inner upper lid 321 tightly to the inner base 322 .
- An outer shell 31 ′ includes an outer upper lid 311 ′ to cover an outer base 312 ′.
- An inner shell 32 ′ is housed in the outer shell 31 ′.
- the inner shell 32 ′ has a hollow housing chamber 320 ′ for installing an air pump body 4 ′.
- the outer shell 31 ′ and the inner shell 32 ′ are interposed by a hollow space 310 ′.
- the inner side of the outer upper lid 311 ′ has an indented and downward lid rim 3110 ′ to hold a soft pad 33 ′ for covering to the top rim of the inner shell 32 ′.
- the inner shell 32 ′ has at least one notch 3210 ′ to enable an air discharge duct 41 ′ to run through.
- noise resulting from vibrations during air pump operation may be reduced from leaking out.
- people can enjoy the pleasure of breeding pet fish and the serenity of the house can be maintained.
