Abstract
Description
- The present invention relates to an automatic cleaning device for paint sprayer gun, in particular, to an automatic cleaning device for paint sprayer gun, for which compressed air is used as a power source to repeatedly cycling the solvent in a container for automatically cleaning a paint sprayer gun.
- In a conventional paint sprayer gun, it is normally composed of a gun body, a nozzle, and a paint container, where the nozzle further includes various components such as a nozzle pipe, an air supplying and cycling pipe etc. In general, the paint sprayer gun must be cleaned after use so as to prevent degrading the performance of the sprayer gun by mingling the old paint color with the new one due to dregs of the old paint remained inside, and moreover, causing damage to the component parts of the sprayer gun.
- Incidentally, a conventional cleaning device employs an air compressor associated with a pump as its power source. This causes the conventional cleaning device is deemed to operate at high cost and high noise. More severely, the way of motion, such as mechanical rotation or reciprocation (pump motion) that the conventional cleaning device relies on is apt to incur explosion of cleaning solvent (such as benzene) contained in the device owing to electrostatic induction by mechanical friction thereof.
- Aiming at the above depicted defects, the present inventor is to propose a newly developed automatic cleaning device for paint sprayer gun capable of operating at low noise, high security and prolonged lifetime.
- It is an first object of the present invention to provide an automatic cleaning device for paint sprayer gun capable of evading the electrostatic induction accident by mechanical friction during operation.
- It is a second object of the present invention to provide an automatic cleaning device for paint sprayer gun whose solvent can be used repeatedly so as to reduce the operation cost.
- It is a third object of the present invention to provide an automatic cleaning device for paint sprayer gun which can maintain a constant air pressure in the solvent container so as to ensure reliable operation of the device.
- It is a fourth object of the present invention to provide an automatic cleaning device for paint sprayer gun in which a timer is provided to preset the operation time.
- It is a fifth object of the present invention to provide an automatic cleaning device for paint sprayer gun which is equipped with a microswitch on the upper lid of the cleaning tank capable of actuating to interrupt entry of pressurized air into the solvent container when the upper lid is opened so as to shut out injection of the solvent out of the nozzles.
- It is a six object of the present invention to provide an automatic cleaning device for paint sprayer gun capable of releasing the pressurized air out of the solvent container rapidly through an exhaust valve in case the pressure inside the solvent container rises too high so as to protect security of the whole device and the operator as well.
- To achieve these and other objects mentioned above, the paint sprayer gun of the present invention comprises a cleaning tank and a solvent container, a solvent injection pipe provided with at least one nozzle is installed in the cleaning tank. A solvent drain pipe is disposed between the cleaning tank and the solvent container for communicating the two component parts. A solvent supply pipe is inserted into the cleaning tank and its one end is communicating with the injection pipe, while the other end thereof is extended to the bottom of the solvent container. When the pressurized air supplied from an air compressor enters the solvent container via an entry inlet provided on the top of the solvent container, the solvent is forced into the injection pipe so as to perform cleaning work. The used solvent flows back to the solvent container by way of the solvent drain pipe such that the solvent can be used repeatedly. The abnormal pressure in the solvent container is released by the exhaust valve, the operation time for the cleaning device is preset by the timer, and the injection of the solvent from the nozzle is stopped by the microswitch when the upper lid of the cleaning tank is opened as that described above.
- For fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:
- Fig.1 is a cross sectional view of the automatic cleaning device for paint sprayer gun according to the present invention.
-
- Referring to Fig.1, the automatic cleaning device for paint sprayer gun of the present invention comprises a cleaning tank 1, a
solvent container 2, a solvent drain pipe 3, a solvent supply pipe 4, amicroswitch 51, apressure regulation valve 52, atimer 53, anexhaust valve 54, a compressedair supply pipe 7, and an air compressor 8. - The cleaning tank 1 is provided with a removable
upper lid 13 on its top, aninjection pipe 11 equipped with at least onenozzle 12 is disposed in the tank 1. Thebottom portion 14 of the bank 1 is formed into a funnel shape so as to facilitate discarding asolvent 21. - The
solvent container 2 filled with thesolvent 21 has a cap locked on its top. - The solvent drain pipe 3 is communicated with the
bottom portion 14 of the cleaning tank 1 at its one end, while its other end is communicated with thecap 22 of thesolvent container 2. A filter screen 9 is provided at the boundary between the solvent drain pipe 3 and the cleaning tank 1 for filtering adulterant in thesolvent 21, while acheck valve 31 is installed at the entry position of the solvent drain pipe 3 into thesolvent container 2 biassing towards the container side. - The solvent supply pipe 4 communicates with the
injection pipe 11 with its one end perforating the cleaning tank 1 and having aleak proof gasket 42 at the bottom of perforation so as to prevent thesolvent 21 from oozing therefrom, while the other end thereof is extended to the bottom of thesolvent container 2. A three-way tube 41 havingvalves way tube 41, is provided for the solvent supply pipe 4 at the portion above thesolvent container 2, wherein thevalve 411 is for controlling the flow of thesolvent 21 to the injection pipe, and theother valve 412 is for handling replenishment or replacement of thesolvent 21 in thesolvent container 2. - The
microswitch 51 attached to the place where theupper lid 13 is closely fitted with the tank 1 can be triggared to operate when thelid 13 is opened. - The
pressure regulation valve 52 is installed beneath the bottom of themicroswitch 51 for presetting a constant air pressure so as to keep drawing up thesolvent 21 without failing from a low pressure. - The
timer 53 is attached to a side surface of the cleaning tank 1 for setting the time to automatically interrupt the input of pressurized air into thesolvent container 2. - The
exhaust valve 54 is provided on thesolvent container 2 for rapid release of the pressurized air in thesolvent container 2 so as to check drawing up thesolvent 21 from thecontainer 2. - The compressed
air supply pipe 7 is communicated with the air compressor 8 at its one end, while its other end thereof is successively connected to themicroswitch 51, thepressure regulation valve 52, thetimer 53, theexhaust valve 54, and finally thecap 22 of thesolvent container 2 such that the pressurized air can be introduced into thesolvent container 2. Besides, avalve 6 is installed at the outlet of the pressurized air of the air compressor 8 for controlling the compressed air output. - At the beginning of the cleaning operation, the pressurized air is produced by the air compressor 8. At first, the air pressure is regulated to a prescribed value by the
valve 52, and then sent into thesolvent container 2 by way of thetimer 53 and theexhaust valve 54. At this instance, thecheck valve 31 located at the boundary between the solvent drain pipe 3 and thesolvent container 2 closes as soon as it has detected compressed air entry to the cleaning tank 1 so as to maintain sufficient air pressure in thesolvent container 2 to draw up thesolvent 21 into the cleaning tank 1 via the solvent supply pipe 4. At this moment, thevalve 411 at the midway of the solvent supply pipe 4 is in open state, while theother valve 412 thereof is in closed state so that thesolvent 21 is able to be transported into theinjection pipe 11 in the tank 1 and injected out of thenozzle 12 to clean the sprayer gun. The injectedsolvent 21 is deposited on the bottom of the tank 1 after completion of the cleaning work. Thecheck valve 31 automatically opens as soon as the compressed air stops to enter thesolvent container 2 so as to allow thesolvent 21 to return to thecontainer 2 via the solvent drain pipe 3. In this way thesolvent 21 in thecontainer 2 can be used repeatedly until the pressurized air ceases to enter thecontainer 2. - In case during the operation of the cleaning device, the
upper lid 13 of the cleaning tank 1 is inadvertently removed, the compressed air is instantaneously interrupted from entering thesolvent container 2 by actuation of themicroswitch 51, and simultaneously, the pressurized air in thesolvent container 2 is automatically discharged by theexhaust valve 54 so that the solvent supply pipe 4 can not continue to draw thesolvent 21, and thenozzle 12 is unable to inject thesolvent 21 any more thereby assuring the operation security of the cleaning device. If it is desired, thetimer 53 may be used to preset the operation time of the cleaning device. As soon as the time is over, the entry of the pressurized air into thesolvent container 2 is interrupted to cease the cleaning work. - Meanwhile, for replacing the
solvent 21 in thecontainer 2, by closing thevalve 411 and opening the other one 412, thesolvent 21 in thecontainer 2 is conducted out of thecontainer 2 for replacement. - It emerges from the above description that the invention has several noteworthy advantages, in particular:
- 1.The hazardous electrostatic induction accident arising from the mechanical friction can be evaded because the power source for the present invention is compressed air.
- 2.The cleaning solvent is repeatedly usable so as to cat down the operational cost.
- 3.A relevant and constant air pressure can be maintained in the solvent container so as to ensure reliable operation of the device.
- 4.A timer can be utilized to preset the operation time.
- 5.A microswith can be utilized to interrupt entry of the pressurized air into the solvent container should the upper lid of the cleaning tank is opened inadvertently so that injection of solvent from the nozzle can be stopped too,
- 6.An exhaust valve is provided to release the pressurized air out of the solvent container instantly in case the pressure inside the solvent container rises to a hazardous value so as to protect the security of the whole device and the operator as well.
-
- Although the invention has been described in terms of a preferred embodiment, it is apparent that numerous variations and modifications may be made without departing from the true spirit and scope thereof, as set forth in the following claims.
