AIR PIPE DEVICE OF AIR COMPRESSOR

An air pipe device of an air compressor contains a connector of an air pipe configured to output fluid pressure so as to inflate airs and to feed sealant when the air compressor operates. The air pipe device contains a connection pipe, and the connection pipe includes an open segment defined on a first end thereof and configured to connect with the connector of the air pipe of the air compressor. In addition, the connection pipe includes a stop segment formed on a second end thereof, such that the connection pipe is configured to connect a twin tire with the connector of the air compressor so as to inflate airs and feed sealant.

FIELD OF THE INVENTION

The present invention relates to an air pipe device of an air compressor which is configured to feed sealant and inflate airs to a broken twin tire.

BACKGROUND OF THE INVENTION

A conventional air compressor is portable onto a vehicle so as to inflate airs and to feed sealant into a broken tire.

However, when desiring to inflate airs and feed sealant into a broken twin tire inclusive of an internal tire and an internal tire, it is troublesome to inflate airs and feed sealant into the internal tire and the external tire of the twin tire. For example, a first nozzle of the internal tire is back to a central axis between a front end and a rear end of the vehicle, so it is difficult for a user to manually connect a connector of a connection pipe with the first nozzle of the internal tire. Moreover, a second air nozzle of the external tire faces to the central axis of the vehicle. In other words, the second air nozzle of the external tire is back to the user's eyes, so it is difficult to manually extend the air pipe into the through orifice of the rim of the external tire and to rotate the connector of the connection pipe reversely, thus screwing the connector with the second nozzle of the external tire. However, a flexible hose bends excessively when rotating the air pipe of the air compressor to stop inflating the airs into the twin tire.

Since the turning-on mechanism and the check mechanism are a well-known art, the embodiments of the present invention disclosed are only for convenience of presentation and not for limitation.

With reference toFIGS. 1-12, the air pipe device of the air compressor according the present invention, the connector93of the air pipe92of the air compressor (as shown inFIGS. 4-10) is capable of feeding sealant and inflating airs to a broken twin tire. The connection pipe1includes an open segment11defined on a first end thereof and a stop segment12formed on a second end of the connection pipe1. The open segment11of the connection pipe1has male threads111formed thereon, the connection pipe1has the check mechanism112received therein, and the connection pipe1includes an air core114mounted on the check mechanism112. The stop segment12has female threads121formed on an inner wall thereof and accommodates the turning-on mechanism2having the post24, and a seal ring123is fitted on an outer wall of the post24.

The air compressor is received in a box9and is configured to inflate the airs or is connected with a sealant supply91, as shown inFIG. 4.

The stop segment12of the connection pipe1has a positioning orifice122defined thereon.

The turning-on mechanism2includes a column21accommodated in the positioning orifice122, an annular section22formed on an end of the column21and having a diameter less than a diameter of the column21, a contact fringe23defined between the column21and the annular section22, and the post24extending outward inside the annular section22, wherein at least one conduit241is defined between the post24and the annular section22, and the at least one conduit241is in communication with the connection pipe1, wherein the seal ring123is put from the positioning orifice122of the connection pipe1to contact with the contact fringe23of the turning-on mechanism2.

As illustrated inFIGS. 4-6, the twin tire includes an internal tire80and an external tire85, wherein a first air nozzle8of the internal tire80is located inside the external tire85. The first air nozzle8of the internal tire80faces a user, but the external tire85interrupts the user to operate the air compressor. Accordingly, the connection pipe1is inserted through a through orifice83of a rim of the external tire85to contact with the first air nozzle8of the internal tire80, and the stop segment12of the connection pipe1is connected with the first air nozzle8of the internal tire80. The open segment11of the connection pipe1is connected with the connector93of the air pipe92of the air compressor, thus feeding the sealant and inflating the airs smoothly. A second air nozzle86of the external tire85faces a central axis of a vehicle, i.e., back to the user's eyes, so it is difficult to connect the connector93of the air pipe92of the air compressor with the second air nozzle86of the external tire85. When desiring to inflate the airs or feed the sealant into the internal tire80of the twin tire, the stop segment12of the connection pipe1is connected with the first air nozzle8of the internal tire80, as illustrated inFIGS. 5 and 6, and the post24of the turning-on mechanism2of the stop segment12abuts against and moves the air core81of the first air nozzle8of the internal tire80so that when a valve82of the first air nozzle8is turned on, the first air nozzle8of the internal tire80communicates with the connection pipe1. In other words, the valve82of the first air nozzle8of the internal tire80, the at least one conduit241of the turning-on mechanism2of the stop segment12, and the connection pipe1communicate. Furthermore, the open segment11of the connection pipe1is configured to avoid a leakage of an air pressure or the sealant from the internal tire80so that after the stop segment12of the connection pipe1is connected with the first air nozzle8of the internal tire80, the connector93of the air pipe92of the air compressor is connected with the open segment11of the connection pipe1, and the connector93abuts against the air core114of the check mechanism112of the open segment11to turn on the valve113of the stop mechanism112, thus feeding the sealant and inflating the airs.

With reference toFIGS. 7-9, a difference of an air pipe device of an air compressor of a second embodiment from that of the first embodiment from comprises: a connection pipe4including a flexible hose40, a resilient cylinder3fitted on the flexible hose40to protect the flexible hose40when the flexible hose40bends excessively, such that the flexible hose40does not deform to block the sealant and the airs. The flexible hose40includes an open segment41formed on a first end thereof, and the flexible hose40includes a check mechanism7defined in the open segment41. The check mechanism7includes a fitting shaft71formed on a first end thereof, a male threaded section72formed on the fitting shaft71, and a stepped coupling section73extending from a second end of the fitting shaft71opposite to the fitting shaft71, wherein the stepped coupling section73of the fitting shaft71is fitted on the open segment41of the flexible hose40, and a first defining sleeve31is configured to connect the flexible hose40with the stepped coupling section73of the fitting shaft71. The flexible hose40further includes a stop segment42formed on a second end thereof, and the flexible hose40includes a turning-on mechanism5received in the stop segment42. The turning-on mechanism5includes a bushing50, a column61, a seal ring123, an accommodation chamber51defined in the bushing50, a threaded screw orifice52formed on an inner wall of a first end of the bushing50, a passing orifice53defined on a second end of the bushing50, and a neck54formed adjacent to the passing orifice53, wherein a diameter of the neck54is more than a diameter of the passing orifice53, and the threaded screw orifice52, the accommodation chamber51and the passing orifice53communicate.

The column61has an annular section62extending from the column61, wherein a diameter of the annular section62is less than a diameter of the column61, and a contact fringe63is formed between the annular section62and the column61, a post64extends from the annular section62, at least one conduit65is defined between the post64and the annular section62, a stepped coupling section66extends opposite to the column61, a recessed section67formed on an outer wall of the column61proximate to the stepped coupling section66, wherein a diameter of the column61is more than a diameter of the recessed section67, and a joining shoulder68is formed on the recessed section67and the column61, wherein a channel69defined between the column61and the stepped coupling section66, and the at least one conduit65, the channel69and the flexible hose40communicate. A seal ring123is put from the column64to contact with the contact fringe63of the column61. The stepped coupling section66of the column61connected with the seal ring123is received in the accommodation chamber51from the threaded screw orifice52of the bushing50via the passing orifice53of the neck54, wherein the neck54abuts against the joining shoulder68of the column61, the stepped coupling section66of the column61exposing outside the bushing50is fitted with the stop segment42of the flexible hose40, and a first defining sleeve32is configured to connect the flexible hose40with the stepped coupling section66of the column61. When the open segment41of the flexible hose40is not forced by an external force, the check mechanism7closes the valve75of the air core74completely, as illustrated inFIGS. 9 and 12.

Referring toFIGS. 10-12, when desiring to feed the sealant and inflate the airs into the external tire of the twin tire, the second air nozzle86of the external tire85faces a central axis of a vehicle, i.e., back to the user's eyes, so the stop segment42of the flexible hose40is connected with the second air nozzle86of the external tire80, and the post64of the turning-on mechanism5abuts against and moves the air core87of the first air nozzle86of the external tire85so that when the valve88of the first air nozzle86is turned on, the second air nozzle86of the external tire85communicates with the flexible hose40. In other words, the valve88of the first air nozzle86of the external tire85, the at least one conduit65and the channel69of the column61of the stop segment42, and the flexible hose40communicate. Furthermore, the open segment41of the flexible hose40is configured to avoid a leakage of the airs from the external tire85so that after the stop segment42of the flexible hose40is connected with the second air nozzle86of the external tire85, the open segment41of the flexible hose40is rotated outside the external tire85, in the meantime, the flexible hose40is protected by the resilient cylinder3so that the flexible hose40does not bend to block the sealant and the airs. Thereafter, the connector93of the air pipe92of the air compressor is connected with the open segment41of the flexible hose40, and the connector93abuts against the check mechanism7of the open segment41to turn on the valve75of the air core74, thus feeding the sealant and inflating the airs.

Thereby, the connector93of the air pipe92of the air compressor is connected with the connection pipe1to feed the sealant and inflate the airs. The connection pipe1includes the open segment11formed on the first end thereof and a stop segment12formed in the second end of the connection pipe1so that when the stop segment12is connected with the air nozzle of the twin tire, the open segment11of the connection pipe1is configured to avoid the leakage of the airs from the twin tire, and the stop segment12of the connection pipe1is connected with the air nozzle of the twin ire, and the connector93of the air pipe92of the air compressor is connected with the open segment11of the connection pipe1to feed the sealant and inflate the airs. After inflating the airs, the connection pipe1is removed from the connector93, thus stopping the leakage of the airs from the twin tire.
