In the above ceramic pre-wetting spraying device, the water inlet channel comprises an annular groove which is arranged at the front end of the pre-wetting body and is communicated with the inner end of the water outlet hole, and the rear end face of the pre-wetting body is provided with a water inlet hole communicated with the annular groove along the axis of the pre-wetting body.

In the above ceramic pre-wetting sprayer, the pre-wetting nozzle cap is an elastic body.

In the above ceramic pre-wetting spraying device, the water outlet through grooves are circumferentially and uniformly distributed on the inner conical surface.

In the ceramic pre-wetting spraying device, the connecting part is arranged in the middle of the pre-wetting body, and the rear end face of the pre-wetting nozzle sleeve abuts against the front end face of the connecting part, and the inner conical surface of the front port abuts against the outer conical surface.

Compared with the prior art, the utility model has the outstanding advantages that:

1. according to the utility model, the inner conical surface is attached to the outer conical surface, so that a water outlet hole is formed between the water outlet through groove and the outer conical surface, and meanwhile, water flow can form a certain spraying angle along the two conical surfaces during water outlet, so that pre-wetting of ceramics can be realized in the largest range;

2. the utility model has the advantages that the water outlet hole is small in size and is easy to block in practical use, and the elastic structure of the pre-wetting nozzle sleeve is convenient to clean the blocked water outlet hole.

Description of the drawings:

FIG. 1 is an overall perspective view of the present invention;

FIG. 2 is an overall exploded view of the present invention;

fig. 3 is an overall sectional view of the present invention.

In the figure: 1. pre-wetting the body; 2. pre-wetting the nozzle sleeve; 3. an annular convex edge; 4. an outer conical surface; 5. an inner conical surface; 6. a water outlet through groove; 7. an annular groove; 8. a water inlet hole; 9. a connecting portion.

The specific implementation mode is as follows:

the utility model will now be further described by way of specific examples, with reference to figures 1 to 3:

the utility model provides a pottery spraying device that wets in advance, including wetting body 1 in advance and the dress wetting spray head cover 2 in advance at 1 front end tip of wetting body in advance, the front end tip of wetting body 1 in advance is equipped with annular protruding edge 3, and the protruding rear end face along 3 of annular is the external diameter preceding big back little external cone face 4, the preceding port inner wall of wetting spray head cover 2 in advance has been seted up a plurality of for the cover and has been passed through groove 6 for establishing at the internal conical surface 5 on the external cone face 4, and on the internal conical surface 5 along the fore-and-aft direction, goes out to form the apopore between groove 6 and the external cone face 4, sets up the inlet channel who communicates with the downthehole port of apopore on wetting body 1 in advance.
