Referring to FIGS. 1 to 6 together, the nozzle 100 for a spray device according to the present embodiment includes a nozzle body member 110 and a sieve member 120, and is coupled to the opening / closing valve 10.

The on-off valve 10 includes a valve body 11 and a plunger 12 which can be raised or lowered from the valve body 11 and is capable of being raised and lowered. The valve body 11 is formed in a solenoid type, And an electromagnet. Then, when a signal and electricity are applied from the outside, the plunger 12 can be lowered from the valve body 11 so as to be raised or contracted. Since the solenoid-type on-off valve 10 is a general one, a detailed description thereof will be omitted here.

A plunger gasket 13 is provided at an upper end of the plunger 12 so that the plunger gasket 13 can block the injection hole 115 described later.

The nozzle body member 110 is connected to a spray target receptacle such as a spray can containing the spray target object and injects the spray target object supplied from the spray target receptacle to the outside, Off valve 10 is coupled so that the external injection of the fuel gas can be turned on and off.

The nozzle body member 110 includes a nozzle body 111 having a communication hole 116 formed therein and a spray object receptacle connection portion 112 formed at one side of the nozzle body 111 and connected to the spray object receptacle, A spray object inlet hole 113 penetrating the spray object receptacle connection part 112 to communicate the spray object and the communication hole 116 and a nozzle body 111 having a shape protruding at a predetermined length on the nozzle body 111 And a spray hole 115 for spraying the sprayed object passing through the spray hole 114 through the communication hole 116 to the outside.

The spray target accommodated in the spray target receptacle may be introduced into the communication hole 116 through the spray target inflow hole 113 and then injected to the outside through the injection hole 115.

A thread is formed in the spray object receptacle connection part 112 to engage with a thread formed in the coupling part of the spray object receptacle so that the spray object receptacle can be firmly coupled to the spray object receptacle connection part 112.

A valve coupling part 118 to which the valve body 11 can be coupled is formed at the lower end of the nozzle body 111. A screw thread is formed in the inside of the valve coupling part 118 so that the valve body 11 is engaged with the thread formed on the outer surface of the valve body 11 so that the valve body 11 can be firmly coupled to the valve coupling part 118 do.

The sieve member 120 is disposed on the nozzle body member 110 to remove and remove foreign substances such as dust from the nozzle body member 110.

In detail, the sieve member 120 is made of polyester or the like and is formed so as to be able to remove foreign matter such as dust, and may be formed in the form of a nonwoven fabric.

A sieve passage through hole 122 is formed at the center of the sieve body 121 constituting the sieve member 120 so that the plunger 12 can be moved up and down through the sieve passage hole 122.

The sieve member 120 is disposed between the communication hole 116 and the opening / closing valve 10. A filtering mesh part 117 is formed between the communication hole 116 and the valve mesh part 118 which is a lower part of the nozzle body 111 and the filtering mesh part 120 May be provided to cover the communication hole 116 from the lower side.

The filtering mesh portion 117 is formed in a stepped shape around the lower end of the communication hole 116 to allow the outer portion of the filtering mesh member 120 to be caught.

The spray nozzle 100 may further include a sieve fixing member 130 for fixing the sieve member 120 to the sieve coupling part 117.

In detail, the sieve fixing member 130 includes a sieve fixing body 131 which covers the sieve member 120 and is coupled to the sieve coupling part 117, A plunger lifting and lowering hole 132 formed in the body 131 and a foreign matter passing through the sludge fixing body 131 so that foreign matter in the nozzle body 111 can flow toward the sieve member 120 by a negative pressure, And includes a through hole 133.

The sieve fixing body 131 may be coupled to the sieve coupling part 117 while covering the sieve member 120 from the lower side of the sieve member 120. When the valve body 11 is coupled to the valve coupling portion 118 in a state where the filtering element 120 and the filtering wire fixing member 130 are inserted into the filtering wire coupling portion 117, The squeezing member 120 and the squeezing net fixing member 130 can be prevented from being pushed and released.

The plunger lifting hole 132 is formed at the center of the sieve fixing body 131 like the sieve through hole 122 so that the plunger 12 can be lifted and lowered.

A plurality of foreign matter through holes 133 are formed in the periphery of the plunger lifting hole 132 and are formed in a space between the communication hole 116 and the valve body 11, So that the foreign substances in the space between the valve bodies 11 can flow toward the communication hole 116. [

The spray target object supplied from the spray target object receiver to the communication hole 116 through the spray target inflow hole 113 is guided to the spray hole 115 via the communication hole 116 A negative pressure is formed in the communication hole 116 and a foreign substance in the nozzle body 111 is sucked toward the communication hole 116 by the negative pressure as described above, Through the through hole (133) and caught by the sieve member (120).

Hereinafter, the operation of the spray nozzle 100 will be briefly described.

5, when the plunger 12 is in a lowered state, the spray hole 115 is opened, so that the spray target object, which has flowed through the spray target object inlet hole 113, And then injected into the hole 116 through the injection hole 115.

At this time, the foreign substance inside the nozzle body 111 is sucked toward the communication hole 116 by the negative pressure formed in the communication hole 116 in the spraying process of the spray target object, and passes through the foreign matter penetration hole 133 And is caught by the sieve member 120 and removed.

6, when the plunger 12 is in the raised state, the plunger gasket 13 closes the spray hole 115, and the spray object 115 is sprayed through the spray hole 115, Is stopped.

As described above, since the nozzle 100 for the spray device includes the nozzle body member 110 and the sieve member 120 capable of filtering out foreign substances in the nozzle body member 110, Foreign substances in the nozzle body member 110 can be automatically removed by using a negative pressure generated in the injection process so that foreign matter such as dust to the opening and closing valve 10 installed in the nozzle body member 110 The failure, malfunction, and the like can be minimized.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as set forth in the following claims It will be understood that the present invention may be modified and changed without departing from the spirit and scope of the invention. However, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.

According to the spray nozzle according to one aspect of the present invention, the influence of foreign matter such as dust on the opening / closing valve provided in the nozzle can be minimized, so that the use of the spray nozzle is industrially high.
