Abstract

A nozzle structure has an air pump casing to receive therein the air pump and provided with an outlet defined through a bottom face of the air pump casing and a resilient plate detachably engaging with a peripheral edge defining the outlet of the air pump casing via a guiding element such that air pumped by the air pump is able to push the resilient plate away from the outlet when air is blowing out of the air pump casing and an air pump axle extending out from the air pump is able to push the resilient plate away from engagement with the peripheral edge of the outlet to allow air to flow into the air pump casing.

Claims

exact text as granted — not AI-modified
1 . A nozzle structure in combination with an air pump, wherein the nozzle structure comprises: 
 an air pump casing to receive therein the air pump and provided with an outlet defined through a bottom face of the air pump casing;    a resilient plate detachably engaging with a peripheral edge defining the outlet of the air pump casing via a guiding element such that air pumped by the air pump is able to push the resilient plate away from the outlet when air is blowing out of the air pump casing and an air pump axle extending out from the air pump is able to push the resilient plate away from engagement with the peripheral edge of the outlet to allow air to flow into the air pump casing.    
   
   
       2 . The nozzle structure in combination with the air pump as claimed in  claim 1 , wherein the air pump casing has a bar extending from two points in the outlet and the guiding element comprises a guiding bar with a head and an extension extending through an extension hole in the bar, a guiding plate with a tube extending from a face of the guiding plate to receive therein a free end of the extension and a spring mounted around the tube to allow the guiding plate to move relative to the air pump casing.  
   
   
       3 . The nozzle structure in combination with the air pump as claimed in  claim 2 , wherein the guiding plate has a disk with the tube formed on top of the disk and two positioning rods to sandwich the tube and correspond to two positioning holes in the bar which has an extension hole centrally defined in the bar to correspond to and allow the tube to extend therethrough.  
   
   
       4 . The nozzle structure in combination with the air pump as claimed in  claim 3 , wherein the resilient plate is securely attached to a bottom face of the disk.  
   
   
       5 . The nozzle structure in combination with the air pump as claimed in  claim 4 , wherein the resilient plate has two bosses and the disk has two securing holes defined to correspond to and allow extension of the two bosses of the resilient plate so that the resilient plate is securely attached to the disk.
