Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A liquid sprayer comprising a casing having a support portion, an ultrasonic vibrator carried by said casing, a liquid supply chamber and a liquid absorber for absorbing liquid from said liquid supply chamber and feeding it to said ultrasonic vibrator, said liquid absorber being formed of a core material having liquid absorption properties, said core material being covered lengthwise with extending protector plates, said protector plates being secured to each other partially through said core material to increase the value of resistance against liquid current flowing through said liquid absorber, said core abutting against the lateral side of the utmost end of said ultrasonic vibrator in the vibration direction thereof and projecting outwardly of the utmost end of said ultrasonic vibrator, said liquid absorber being supported at the partially fixed portion of said protector plates by said support portion.
Claim 2
Dependent Claim
139 words
A liquid sprayer comprising a casing having a support portion, an ultrasonic vibrator carried by said casing, a liquid supply chamber and a liquid absorber for absorbing liquid from said liquid supply chamber and feeding it to said ultrasonic vibrator, said liquid absorber being formed of a core material having liquid absorption properties, said core material being covered lengthwise with extending protector plates, said protector plates being secured to each other partially through said core material to increase the value of resistance against liquid current flowing through said liquid absorber, said core abutting against the lateral side of the utmost end of said ultrasonic vibrator in the vibration direction thereof and projecting outwardly of the utmost end of said ultrasonic vibrator, said liquid absorber being supported at the partially fixed portion of said protector plates by said support portion.
Claim 3
Dependent Claim
52 words
A liquid sprayer according to claim 1, wherein said core material is of a thin plate and is sandwiched at both sides thereof with said protector plates each being of a thin plate-like shape in such a manner that all of the lateral and longitudinal sides of the core material are enclosed.
Claim 4
Dependent Claim
42 words
A liquid sprayer according to claim 1, wherein said liquid absorber is formed symmetrically in the longitudinal direction thereof and has two fixed portions of said protector plates at longitudinally symmetrical positions thereof so that the liquid absorber may be turned end-for-end.
