Description

    BACKGROUND OF THE INVENTION 1. Field of the Invention
  • The present invention relates to a single-mouth nozzle head to receive a valve for inflation. The nozzle head can be operated smoothly with one hand to enhance its convenience greatly
  • 2. Description of the Prior Art
  • Conventional dual nozzle heads are as disclosed in Taiwan application No. 095107665 and 097203517 . However, the conventional dual nozzle heads have the following drawbacks.
  1. 1. When the conventional nozzle head is used to pump air, the user needs to hold the main body for controlling the valve to be inserted to a connection mouth with one hand and to push the wrench with the other hand, such that the interior press cylinder is moved downward to clamp the valve for pumping. This way with both hands to operate is inconvenient and wastes time and energy.
  2. 2. The connecting mouth of the conventional nozzle head is deformed axially through the press cylinder to be moved downward. The connecting mouth is indirectly deformed to clamp the valve. The radial deformation of the connecting mouth is quite limited, so the force for the connecting mouth to clamp the valve is also limited. When pumping, it is easy to have a leakage problem.
  3. 3. The entire structure of the conventional nozzle head is too complicated, so the manufacture cost and the assembly cost cannot be lowered.
  • Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.
  • SUMMARY OF THE INVENTION
  • The primary object of the present invention is to provide a nozzle head which can be operated smoothly with one hand for inflation and can be used for different types of valves to be inflated.
  • According to one aspect of the present invention, a single-mouth nozzle head is provided. The nozzle head comprises a main body, an annular first connecting mouth, and a valve plug.
  • The main body has a through valve hole and an air supply hole disposed between two ends of the valve hole.
  • The annular first connecting mouth has a first mouth hole for receiving a valve to be inflated.
  • The valve plug is disposed in the main body. The first connecting mouth is located in the valve plug. The valve plug is axially movable between a first position and a second position of the valve hole. One end of the valve plug is provided with a plurality of clamping claws. The other end of the valve plug is formed with a closed press portion. The interior of the valve plug is formed with a flow passage to communicate with an outer annular wall of the valve plug. A plurality of restraint grooves are formed in between the clamping claws and arranged in a circle to define a restraint hole. The restraint hole and the valve hole are coaxial. The restraint hole is able to contract radially. The outer wall of each clamping claw is formed with a curved portion which is enlarged radially. The restraint hole is for the first connecting mouth to be inserted axially. When the first valve is inserted into the first connecting mouth, the valve plug is moved to the first position and the press portion extends out of the valve hole. The valve hole compresses the clamping claws. Through the guide of the curved portions of the clamping claws, the restraint hole is to clamp the first connecting mouth radially. The air supply hole is in communication with the interior of the valve plug, the flow passage, and the first mouth hole, so that the first valve can be pumped.
  • Accordingly, the present invention has the following inventiveness.
    1. 1. When the present invention is used to pump air, the user can operate the main body with one hand easily. Compared to the prior art operated with both hands, the present invention can be operated more conveniently to save time and labor.
    2. 2. The clamping claws of the present invention directly compress the connecting mouth to deform radially so as to tighten the valve. During inflation, the circumstances of air leakage can be minimized.
    3. 3. The present invention is only composed of four parts, namely, the main body, the first connecting mouth, the second mouth, and the valve plug. The entire structure of the present invention is more simple that the prior art.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The present invention will now be described, by way of example only, with reference to the accompanying drawings.
  • Referring to Fig. 1 to Fig. 4, an automatic-switch nozzle head having two valve mouths is disclosed. The nozzle head comprises a main body 10, an annular first connecting mouth 20, an annular second connecting mouth 30, and a valve plug 40.
  • The main body 10 has a valve hole 11 penetrating upper and lowers of the main body 10 and an air supply hole 12 disposed between two ends of the valve hole 11. The air supply hole 12 is adapted to supply an air pressure source to the valve hole 11. The wall of the lower end edge of the valve hole 11 is concaved and formed with a first engaging portion 13. The wall of the lower end edge of the valve hole 11 is concaved and formed with a second engaging portion 14.
  • The annular first connecting mouth 20 has a first mouth hole 21 for receiving a first valve 91 to be inflated.
  • The annular second connecting mouth 30 has a second mouth hole 31 for receiving a second valve 92 to be inflated.
  • The valve plug 40 is coaxially moved in the valve hole 11 and has a length larger than that of the valve hole 11, such that two ends of the valve plug 40 protrude out of the valve hole 11. The valve plug 40 is formed with a first guide groove 411 and a second guide groove 412 which are not in communication with each other and located within the valve hole 11. The second guide groove 412 is disposed above the first guide groove 411. The outer wall of the valve plug 40 is provided with a first washer 421 under the first guide groove 411, a second washer 422 above the second guide groove 412, and a third washer 423 between the first guide groove 411 and the second guide groove 412. The first washer 421, the second washer 422 and the third washer 423 are against the valve hole 11, providing an airtight effect to the first guide groove 411 and the second guide groove 412. The outer wall of the valve plug 40 is further provided with a first buckle portion 431 to mate with the first engaging portion 13 and a second buckle portion 432 to mate with the second engaging portion 14. When the valve plug 40 is axially moved along the valve hole 11 to a first position, the first buckle portion 431 engages with the first engaging portion 13 and the second buckle portion 432 disengages from the second engaging portion 14. At this time, the first guide groove 411 communicates with the air supply hole 12, and the top end of the valve plug 40 protrudes out of the valve hole 11 for the user to press downward to disengage the first buckle portion 431 from the first engaging portion 13. When the valve plug 40 is axially moved along the valve hole 11 to a second position, the second buckle portion 432 engages with the second engaging portion 14 and the first buckle portion 431 disengages from the first engaging portion 13. At this time, the second guide groove 412 communicates with the air supply hole 12, and the bottom end of the valve plug 40 protrudes out of the valve hole 11 for the user to press upward to disengage the second buckle portion 432 from the second engaging portion 14. Thus, the valve plug 40 is able to move between the first position and the second position. The bottom of the valve plug 40 is provided with a plurality of first clamping claws 44 which are disposed axially. The top of the valve plug 40 is provided with a plurality of second clamping claws 45 which are disposed axially. A plurality of first restraint grooves 46 are formed in between the first clamping claws 44 and arranged in a circle to define a first restraint hole 47 at the inner sides of the first clamping claws 44. The first restraint hole 47 and the valve hole 11 are coaxial, and the first restraint hole 47 is able to contract radially. The outer side of each first clamping claw 44 is formed with a first curved portion for pressing the valve hole 11 radially. The first buckle portion 431 is disposed on the first curved portion. The first restraint hole 47 is adapted for the first connecting mouth 20 to be inserted coaxially, so that the first mouth hole 21 communicates with the first guide groove 411. A plurality of second restraint grooves 48 are formed in between the second clamping claws 45 and arranged in a circle to define a second restraint hole 49 at the inner sides of the second clamping claws 45. The second restraint hole 49 and the valve hole 11 are coaxial, and the second restraint hole 49 is able to contract radially. The outer side of each second clamping claw 45 is formed with a second curved portion for pressing the valve hole 11 radially. The second buckle portion 432 is disposed on the second curved portion. The second restraint hole 49 is adapted for the second connecting mouth 30 to be inserted coaxially, so that the second mouth hole 31 communicates with the second guide groove 412.
  • Referring to Fig. 2 and Fig. 3, when the user operates the main body 10 with one hand to insert the first valve 91 into the first mouth hole 21 of the first connecting mouth 20, the valve plug 40 will be moved to the first position. The first buckle portion 431 engages with the first engaging portion 13 to position the valve plug 40 in the valve hole 11. This moment, the outer walls of the second clamping claws 45 are released from the valve hole 11 to compress the first curved portion formed on the outer wall of each first clamping claw 44, such that the first restraint hole 47 radially tighten the outer wall of the first connecting mouth 20 with the first mouth hole 21 to restrain and fix the first valve 91 directly and radially. After that, through the air supply hole 12 to provide the air pressure source, the first valve 91 is pumped for inflation. After inflation, the top end of the valve plug 40 is pressed downward for the first buckle portion 431 to disengage from the first engaging portion 13, such that the first curved portions formed on the outer walls of the first clamping claws 44 are released from the valve hole 11 to release connection of the first connecting mouth 20 and the first valve 91.
  • Referring to Fig. 4, when the user operates the main body 10 with one hand to insert the second valve 92 into the second mouth hole 31 of the second connecting mouth 30, the valve plug 40 will be moved to the second position. The second buckle portion 432 engages with the second engaging portion 14 to position the valve plug 40 in the valve hole 11. This moment, the outer walls of the first clamping claws 44 are released from the valve hole 11 to compress the second curved portion formed on the outer wall of each second clamping claw 45, such that the second restraint hole 49 radially tighten the outer wall of the second connecting mouth 30 with the second mouth hole 31 to restrain and fix the second valve 92 directly and radially. After that, through the air supply hole 12 to provide the air pressure source, the second valve 92 is pumped for inflation. After inflation, the bottom end of the valve plug 40 is pressed upward for the second buckle portion 432 to disengage from the second engaging portion 14, such that the second curved portions formed on the outer walls of the second clamping claws 45 are released from the valve hole 11 to release connection of the second connecting mouth 30 and the second valve 92.
  • For a stable structure of the present invention, the bottom end of each first clamping claw 44 has a first stop portion 441. The outer edge of the first stop portion 441 is located out of the valve hole 11 to form a diameter larger than that of the valve hole 11. The inner edge of the first stop portion 441 leans against the bottom end of the first connecting mouth 20. The top end of each second clamping claw 45 has a second stop portion 451. The outer edge of the second stop portion 451 is located out of the valve hole 11 to form a diameter larger than that of the valve hole 11. The inner edge of the second stop portion 451 leans against the top end of the second connecting mouth 30. Thus, the valve plug 40 won't disengage from the valve hole 11, the first connecting mouth 20 won't disengage from the first clamping claws 44, and the second connecting mouth 30 won't disengage from the second clamping claws 45. The first stop portion 441 and the second stop portion 451 are adapted to clamp the first valve 91 and the second valve 92, respectively, to prevent the first and second valves 91, 92 from disconnection during inflation.
  • According to the aforesaid illustration, the present invention has the following inventiveness.
    1. 1. The main body of present invention can be operated with one hand to insert the valve into one of the connecting mouths, and the plug valve is moved to a certain position for the valve hole to move the corresponding clamping claws and the connecting mouth to restrain the valve automatically.
