Abstract
The utility model discloses a spray gun, which comprises a hydraulic portion main body (1) and a tank body (3), wherein the hydraulic portion main body (1) is provided with an air cavity (2), and the tank body (3) is used for containing coating materials. The spray gun is characterized by further comprising a connection pipe (4); one end of the connection pipe (4) is communicated with the air cavity (2) of the hydraulic portion main body (1); and the other end of the connection pipe (4) is communicated with the tank body (3). The spray gun has fine energy-saving performance, small waste of the coating materials, and reduces environment pollution.
Description
Technical field
The utility model relates to Gad dynamic coating apparatus, specifically is a kind of spray gun.
Background technology
Present spray gun comprises the hydraulic part body that is provided with air cavity and the tank body of ccontaining coating, coating pipe in the tank body passes the air cavity of hydraulic part body to nozzle, compressed air is from the centre bore ejection of air cavity, form negative pressuren zone at spray nozzle front end, make from the coating of nozzle ejection and enter the high pressure draught district, diffusion is the vaporific coated article surface of flying to rapidly.The spray gun of above prior art still has the following disadvantages: because the coating in the tank body just is sucked out by the negative pressuren zone of spray nozzle front end, when identical quantity for spray, need bigger air pressure like this, could be coating sucking-off from tank body, and energy saving is poor like this; And bigger air pressure makes coating from nozzle ejection easily from being coated with the bounce-back of thing surface, causes unnecessary waste and environmental pollution.
The utility model content
The technical problems to be solved in the utility model is, a kind of good energy saving property is provided, paint waste is little and reduces the spray gun of environmental pollution.
The technical solution of the utility model is, a kind of spray gun with following structure is provided, comprises the hydraulic part body that is provided with air cavity and the tank body of ccontaining coating, it also comprises tube connector, one end of described tube connector is communicated with the air cavity of hydraulic part body, and the other end of described tube connector is communicated with tank body.
After adopting above structure, the utility model compared with prior art has the following advantages: owing to increased tube connector, during use, the air pressure in the air cavity is communicated in the tank body, when identical quantity for spray, only needs less air pressure, just can be coating sucking-off from tank body, good energy saving property like this; And less air pressure can reduce coating from being coated with the bounce-back of thing surface, the little and minimizing environmental pollution of paint waste like this.
As improvement, the stage casing of described tube connector also is provided with the check valve that the coating that prevents tank body flows into air cavity, makes things convenient for the dismounting of hydraulic part body and tank body like this, and prevents that the coating of tank body from flowing into air cavity.
Description of drawings
Accompanying drawing is the structural representation of spray gun of the present utility model.
As shown in the figure: 1, hydraulic part body, 2, air cavity, 3, tank body, 4, tube connector, 5, check valve.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, spray gun of the present utility model comprises the hydraulic part body 1 that is provided with air cavity 2 and the tank body 3 of ccontaining coating, and it also comprises tube connector 4, one end of described tube connector 4 is communicated with the air cavity 2 of hydraulic part body 1, and the other end of described tube connector 4 is communicated with tank body 3.The stage casing of described tube connector 4 also is provided with the check valve 5 that the coating that prevents tank body 3 flows into air cavity 2.
Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.Structure of the present utility model can have other variations, is not limited to said structure, and in a word, all various variations of being done in the protection domain of the utility model product independent claims are all in protection domain of the present utility model.
Claims (2)
1. spray gun, comprise the hydraulic part body (1) that is provided with air cavity (2) and the tank body (3) of ccontaining coating, it is characterized in that: it also comprises tube connector (4), one end of described tube connector (4) is communicated with the air cavity (2) of hydraulic part body (1), and the other end of described tube connector (4) is communicated with tank body (3).
