Abstract

The present invention relates to a device used for giving out a fine liquid particle flow, said device includes a manual pump capable of directly providing air for nozzle by using pressure. The position of said nozzle is such that air from it points and crosses the pen point of its pen-shaped container. The said container is removably mounted in a frame, and its pen point is tightly nestled against the outlet of the nozzle, so that the liquid out of the ocntainer flows as a fine particle flow with air. Said pump includes a deformable bulb fixed on the inlet end of the nozzle, and a reinforcing rib positioned behind the circular shoulder formed on the external surface of the nozzle component when the bulb is mounted on the nozzle.

Description

The relevant improvement of liquid dispensing apparatus

The present invention relates to a kind of device that provides tiny liquid particle stream, more particularly (but not being unique) relates to a kind of liquid feeder that is called the air writing brush.

BP No.2245196B discloses a kind of device that provides tiny liquid particle stream, it comprises a foot-propelled pump, this pump directly links to each other with nozzle with the compressed-air actuated flexible pipe of supply, the position that nozzle is put to make the air that leaves nozzle towards and cross the nib of a pen-shaped container, container removably is contained in the shelf, make the nib of pen-shaped container be close to the outlet of nozzle, the liquid that comes out from pen is provided with aeriferous tiny liquid particle stream.

It is very heavy to it is found that this early stage liquid feeder uses, and manufacturing expense is more expensive.

The liquid feeder that the purpose of this invention is to provide a kind of simplification, it comprise one with the direct coupled manual pump of hand-held nozzle, do not need flexible pipe.The present invention also provides a kind of liquid feeder, and manual pump wherein connects with nozzle securely, prevents to move in use.

According to the present invention, a kind of device that provides tiny liquid particle stream is provided on the one hand, this device comprise one its be shaped as the manual pump of a deformable bubble, bubble is fixed on the entrance point place of nozzle, the position that nozzle is put to make the air that is pumped that leaves nozzle towards and cross a nib that the pen of felt end arranged, but be contained in to this pen demolition in the shelf, make the nib of the pen of felt end be close to the outlet of nozzle, the droplet that comes out from nib is provided with aeriferous tiny liquid particle stream.

The most handy glue of bubble is fixed on the nozzle, and preferably includes a locating surface, and in use, the shoulder of the pen that felt end arranged adjacent with its nib just leans against on this face, to guarantee that nib has correct positioning with respect to jet expansion.

When using this device, nozzle and pen can be contained in the passage separately of the shelf that can separate, and these passages tilt mutually, so that leave the nib that the compressed air of nozzle directly flowed to and crossed pen.

The passage of placing pen can limit with a sleeve pipe that removably is fixed in the shelf.Can the pen with different-diameter and cross section can both be placed in the shelf with more than one this sleeve pipe.

On the other hand, for instance, but the passage of placing pen can be that demolition ground is fixed on the sleeve pipe in the shelf, and it can be done for example can have and be out of shape and/or the inner flange or the shoulder of elastic performance, can so arrange and configuration, can be mounted in it so that have the pen in different-diameter and cross section.

Liquid can be dyestuff, as ink or edible food color.

According to a further aspect in the invention, a kind of device that is used to provide tiny liquid particle stream is provided, this device contains one and is suitable for a hand-held liquid feeder firmly, and comprise a manual deformable bubble, this bubble connects securely with liquid feeder, and directly supplies air to the nozzle of liquid feeder with pressure.The position that nozzle is put to make the air that leaves nozzle towards and the end of crossing the pen of felt end, pen removably is contained in the shelf of liquid feeder, the felt end of pen is close to the outlet of nozzle, provides with aeriferous fine particle stream so that bring out the liquid particle that comes from the felt of pen.

Only describe the present invention now with reference to the accompanying drawings by way of example, these accompanying drawings are:

Fig. 1 is the perspective view according to air writing brush device of the present invention;

Fig. 2 is the front view of the part of device shown in Figure 1; And

Fig. 3 is the cutaway view of the assembly of the manual pump of shown device and nozzle.

Air writing brush shown in Fig. 1 and 2 comprise one its be shaped as the manual pump 1 of a deformable bubble, bubble is with for example such material manufacturing of rubber, links to each other with nozzle 2 in first passage 3 that is contained in plastic processing frame 4.Shelf 4 comprises second passage 5, and sleeve pipe 6 is housed therein movably.Overlap effective corresponding screw attachment and be fixed on the appropriate location.Be fixed in the sleeve pipe 6 be one have the felt end the pen 8.

Passage 3,5 tilts mutually, so that the outlet of nozzle is close in the position of the end 9 of pen 8.When adopting nozzle shown in Figure 1, the position of the shoulder 11 adjacent with end 9 will be against step 10, to play the effect of location.

The design of shelf 4 will make it and prepare to apply the distance of workpiece maintenance one regulation of fine particle stream.Operation manual pump 1 makes air directly flow through nozzle 2 under the effect of pressure.When this compressed air passes through the end 9 of pen, just produce the particle of tiny dispersion.

Twist over now and see Fig. 3, can see that the end 12 that the nozzle 2 of bubble 1 openend 14 is housed includes, and is arranged in order thereon, its termination is the sloping portion 15 of upright ring-shaped step 16, and its termination is second sloping portion 17 and the annular end step 19 of ring-shaped step 18.Bubble 1 comprises that its length is substantially equal to the annular ribs 21 that the neck 20 and of the length of nozzle-end 12 inwardly stretches out, and rib is positioned at the junction of neck 20 and the main part of bubble 1.

When assembling, firmly neck 20 was overlapped the sloping portion 15,17 of nozzle, until the close end, end of neck step 19.At this moment, ring-shaped step 16 just is positioned at the back of the annular ribs 21 of bubble, and guarantees, even in bubble or nozzle pressure is arranged, bubble still is firmly held on the nozzle.Find that once when not having rib 21 and step 16, if tension or extruding bubble too quickly, nozzle can gush out from bubble.

Also can will steep 1 with other method links up with nozzle 2.For example, can be coated on nozzle and bubble one or each composition surface with glue.

As previously mentioned, pen 8 can comprise the end of a felt.On the other hand, it also can comprise a chuck, contains technical drawing pen, traditional Pen nib or pen-shaped hydrostatic column on the chuck, for example comprises the leaching pipe that can drink up by its dyestuff that ink is such in the container.In addition, use this device, also can provide edible food color, red ink paste used for seals base polypropylene and emulsification paint.Select different sleeve 6 for use, just can utilize various fluid supply.

The description that should be known in the front only is an embodiment according to liquid dispensing apparatus of the present invention, can make improvements at an easy rate under the preceding topic of the true scope of the present invention that does not break away from the appended claims proposition simultaneously.
