Abstract

The invention provides a paint container structure of a spray gun. The paint container structure is composed of a body, a cover body and a ventilating component. The body is of a container used for containing paint solvent, and an opening of the body is used for fastening the cover body. The cover body is provided with a hollow jointing section which is pivoted with the spray gun. The surface of the cover body is provided with an air vent, and the air vent is of a sleeve section which penetrates relative to the internal surface of the cover body. The sleeve section is convexly extended with an inner pipe body sleeved with a ventilating element, and an extending section of an outer pipe body can just be embedded in the sleeve section. When the body is overturned to be used, the paint solvent originally arranged at the gap of the ventilating element and the inner pipe body can flow to a volume tank of the sleeve section by means of the pipe wall of the inner pipe body so as to enable the body keep airflow flowing in the air vent, so that when the spray gun is used, thereby achieving the purpose that the paint solvent can smoothly flow into the spray gun to be used through the paint container.

Description

The paint container structure of spray gun for paint

Technical field

The present invention relates to a kind of paint container structure of spray gun for paint, mainly referring to can be because the paint body not block passage, can keep air current flow with the lid ventilation device of the spray gun for paint container of keeping the spray gun for paint function.

Background technology

Describe among disclosed US Patent No. 2010/0301049 A1 on December 2nd, 2010 " LID FOR MIXING CUPS OF PAINT GUNS " (a kind of lid of spray gun for paint mixer) a kind of for spray gun for paint can closed mixer lid, this lid is provided with a blow vent, blow vent forms to have three and mutually embeds, and allows to each other Air Flow in a labyrinth type meander-like closed structure of pipe body.Provide a cylindrical body and a lid integrally formed according to the description of its embodiment, and another is located in the cylindrical body than the roundlet body and open towards the top; One cover piece is arranged on the bottom of pipe body and cylindrical body, and this cover piece is to comprise circular tube shaped parts that extend upward, and the length of these circular tube shaped parts is less than pipe body and cylindrical body; One cover piece is to insert crack between pipe body and the cylindrical body with the circular tube shaped parts, and with the inner space of cover piece closed circular body, but complete closed not; Air can enter the space between pipe body and cylindrical body via the bottom in crack between pipe body and the cylindrical body, means the position of circular tube shaped parts device; Air from then on bottom upwards can be by circular tube shaped parts and continuous circulation downwards, and because of the concrete shape of cover piece, the inner space that the bottom air can be entered into again mix glass; Yet the paint liquid that is arranged in the inner space can not penetrate this airway and arrive outside; On the one hand, because the low pressure that exists during operation, on the other hand because the stickiness of liquid makes it can't pass through this airway, liquid can only enter at most the distance in one little section in space between cylindrical body and circular tube shaped parts, and can not affect usability.

According to the described technical scheme of embodiment, be provided with a hollow cylindrical body within the lid, and the pipe body is located in the cylindrical body, this pipe body is a hollow and passes through that to be connected to lid be a blow vent; Another cover piece is located at the bottom of pipe body and cylindrical body, and with the set circular tube shaped parts of a cover piece, puts crack between pipe body and the cylindrical body; The length of the set circular tube shaped parts of cover piece is shorter than pipe body and cylindrical body and cover piece and is not completely enclosed within two bodys, and produces an air flow channel again; Precisely because described, when the attaching parts of lid engage with spray gun for paint and overturn, and the paint liquid of inner space is because of the concrete shape of the circular tube shaped parts of cover piece, can make gas flow into the inner space, and the paint liquid that covers flows into the space that places cylindrical body and circular tube shaped parts, though wouldn't affect the start of spray gun for paint, when quitting work maybe need cover, spray gun for paint adds paint and when the inner space become a full member, the remaining lacquer of indwelling in the space of cylindrical body and circular tube shaped parts, both can flow into the bottom of cylindrical body and circular tube shaped parts, this moment also can flow into and pipe body and circular tube shaped parts between the bottom, and the surface that also can adhere to each body because of the stickiness of paint liquid, the crack reduces between must making for a long time between each body, affects the function of blow vent.

Summary of the invention

The technical problem to be solved in the present invention provides between a kind of pipe body and circular tube shaped parts that solves the spray gun for paint container top, formed gas port gap poor effect, and with the passing of time easily make the airflow of painting accumulation and affecting blow vent, make paint container produce the class vacuum phenomenon, and then the defective such as the start when affect the spray gun for paint use is smooth and easy.

In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of paint container structure of spray gun for paint comprises a body, a lid and a ventilation part; This body is a container that the paint solvent splendid attire can be provided, and its openend is established an antelabium and provided with the lid flange and mutually fasten, and the nearly openend of body is established protruding rank for the block contact of lid again; And this lid cooperates an adapter ring that its hollow junction surface and spray gun are articulated, be provided with a passage in top surface in addition, this passage is to connect the fit section set with respect to the lid inner face, this fit section has protruded out an interior tube body, and be provided with an annular groove that the ventilation part eye-splice is provided, wherein, annular groove two inner faces be provided with flange can be with the antelabium clip of ventilation part enlarged portion; One ventilation part is a hollow tube, and the one end is established the annular groove that an enlarged portion just can be embedded in fit section, establishes a catch in relative fit section capacity groove indentation, there again; One adapter ring, an end are provided with external screw thread and can be connected with spray gun, and other end anchor ring is provided with several open-works for fastening in flange place, relative lid hollow junction surface, and its runner loop order of this adapter ring is empty junction surface among the relative lid again, and it is airtight to reach winding; When body upset was used, intrinsic paint solvent liquid flow to the capacity groove of fit section by the interior tube body tube wall, made that the crack still can keep unimpeded between interior tube body and the ventilation part, and air can be followed by passage the Clearance Flow of interior tube body and ventilation part.

Adopt technical scheme of the present invention paint solvent in the ventilation part can be collected in the capacity groove, and can keep Air Flow in the container, it is smooth and easy when the spray gun for paint start is used, the simple and easy not only assembling of member is easy, and can effectively reduce the product fraction defective, and each Components Composition is adopted flange and the assembling of antelabium manner, assembling is disassembled conveniently easily, the design of the annex connector in the technical program can be made positioning fastening with the junction surface of lid, and is fast convenient during use.
