Detailed Description

An art designing spray pen comprises a hollow main body 5, a flow channel is formed in the hollow main body 5, a fluid connector 7 communicated with the flow channel is installed on the upper side of the main body 5, an airflow connector 8 communicated with the flow channel is arranged on the lower side of the main body 5, a connecting piece 4 is connected with the front portion of the main body 5 in a threaded manner or integrally arranged, a nozzle 3 and a spray head 2 are connected and installed on the front portion of the connecting piece 4, the nozzle 3 is sleeved in the spray head 2, a needle valve 15 used for controlling the flow rate of the nozzle 3 is inserted into the flow channel of the main body 5, a valve needle portion at the front end of the needle valve 15 penetrates through the flow channel and then extends into the nozzle 3, an adjusting chamber 5-1 is formed inside the rear end of the main body, a spring retainer ring 11, a spring 12 and a multi-gear positioner 13 which are sequentially sleeved on the needle valve 15 from inside to outside are installed in the adjusting chamber 5-1, the spring retainer ring 11 is fixed on the needle valve 15, the multi-gear positioner 13 is fixed on the inner wall of the adjusting chamber 5-1, the outer side of the multi-gear positioner 13 is provided with a plurality of gear adjusting grooves 13-1 with different depths, the gear adjusting grooves 13-1 with different depths form a circle, the circle and the multi-gear positioner 13 are concentrically arranged, the outer end of the needle valve 15 is fixed with an adjusting knob 14 for rotating the needle valve 15, and one side of the adjusting knob 14, which is close to the multi-gear positioner 13, is provided with a limiting bulge 14-1 matched with the gear adjusting grooves 13-1.

As shown in figures 1-3, the depth of the needle head at the front end of the needle valve 15 in the nozzle 3 is adjusted by the cooperation of the multi-gear positioner 13 and the adjusting knob 14, so as to achieve the purpose of adjusting the size of the spray.

When no external force is applied, the needle 15 is constantly urged toward the one end of the nozzle 3 by the elastic force of the spring 12.

By rotating the adjusting knob 14, when the limiting protrusions 14-1 on the adjusting knob 14 are pressed against the gear adjusting grooves 13-1 with different depths on the multi-gear positioner 13, the utility model has different spraying sizes.

If when the spacing protrusion 14-1 on the adjusting knob 14 is pressed against the deepest gear adjusting groove 13-1 on the multi-gear positioner 13, the needle valve 15 is driven to the position closest to the nozzle 3 by the elastic force of the spring 12, at this time, the needle head of the needle valve 15 is completely plugged into the nozzle 3, and the nozzle 3 is completely sealed, which is equivalent to the utility model discloses be in a closed state of closing. The position at this time corresponds to the 0 position of the shift position.

If the spring 12 is compressed a distance when the limit protrusion 14-1 of the adjusting knob 14 presses against the shallowest shift position adjusting groove 13-1 of the multi-shift position positioner 13, the needle valve 15 is driven to the farthest position from the nozzle 3, and the gap between the needle of the needle valve 15 and the nozzle 3 is maximized, thereby achieving the maximum spraying state. The position at this time corresponds to the maximum spray position of the adjustment gear.

By analogy, when the limiting protrusion 14-1 on the adjusting knob 14 is pressed into the gear adjusting groove 13-1 with the proper depth on the multi-gear positioner 13, the spraying size is proper.

The connecting piece part stretches into the runner of the main body 5, a first sealing ring 6 is arranged between the inner wall of the runner and the connecting piece 4, and the first sealing ring 6 is embedded at the tail end of the runner in the main body 5 and sleeved on the connecting piece 4.

The middle end of the needle valve 15 is sleeved with a second sealing ring 9 through a sealing ring compression screw 10, the second sealing ring 9 is extruded between the needle valve 15 and a flow channel wall in the main body 5, the adjusting chamber 5-1 is communicated with the flow channel, and the second sealing ring 9 is used for sealing and separating.

The front end of the nozzle 3 is fixedly sleeved with a nozzle sleeve 1.

The fluid flow direction in the present invention is the same as the prior art.

In the gear adjusting grooves 13-1 with different depths, the deepest gear adjusting groove 13-1 is adjacent to the shallowest gear adjusting groove 13-1, and the depth of the gear adjusting groove 13-1 is gradually reduced from the deepest gear adjusting groove 13-1 along the clockwise direction or the anticlockwise direction.

In the gear adjusting grooves 13-1 with different depths, the adjacent gear adjusting grooves 13-1 are connected through the guide inclined surfaces 13-2. Rotate more light, whole utility model when using, adjust knob 14 can 360 degrees clockwise turning, also can 360 degrees anticlockwise turning.

The needle valve 15 is controlled to move back and forth in a circular motion mode by the combination of the adjusting knob 14 and the multi-gear positioner 13, a trigger type linkage linear motion structure of the existing design (comprising a starting rod, a shifting block, an adjusting rod, an adjusting screw, a needle valve locking nut, a tail handle, a stroke adjusting screw and a needle valve) is omitted, the number of parts is reduced, the production cost is effectively reduced, the production efficiency and the qualification rate are improved, and the environment-friendly energy-saving emission reduction trend is met.

Aiming at the water leakage and difficult cleaning problems which are most headache for users, the following improvement measures are adopted: the whole structure is shortened in design, the processing is easier, and the precision is ensured; the second sealing ring 9 is machined by a tetrafluoroethylene material, is precise and corrosion-resistant, has good self-lubricating property and prolongs the service life; a fluid interface design is adopted to replace a fixed cup, and a fluid channel on the upper side of the main body 5 is opened; the distance of the fluid channel in the main body is shortened, and the front part and the upper side of the screwed-off nozzle 3 are both opened, so that the main body can be thoroughly cleaned.
