In this embodiment, the cavity injection port 5 communicates with the shower head inlet 3 through the delivery channel 4. The nozzle core 1 comprises a core body 10 and an injection head 11 connected to the tail end of the core body 10, wherein a conveying channel 4 is formed in the core body 10, and a nozzle inlet 3 is formed at the front end of the core body 10; the side wall of the injection head 11 is provided with at least one slot 12 communicated with the conveying channel 4, and the communication port between the slot 12 and the conveying channel 4 forms a cavity injection port 5. In the preferred embodiment, the slot 12 comprises 2, with 2 cavity injection ports 5 formed.
In this embodiment, the bottom of the nozzle cavity 6 in the nozzle cap 2 is provided with a column hole 20 downwards, and the column cavity section 80 is communicated with the bottom of the column hole 20. The bottom of the nozzle cavity 6 is also provided with at least 2 rectangular grooves 21 which pass through the column holes 20 and are communicated with the cylindrical cavity section 80, and the ports of the rectangular grooves 21 communicated with the cylindrical cavity section 80 form a rotational flow inlet 7. In the preferred embodiment, the rectangular slot 21 comprises 4, forming 4 swirl inlets 7 arranged at even intervals.
In this embodiment, the bottom of the nozzle cap 2 is provided with an opening 23 communicating with the nozzle outlet 9, and the diameter of the opening 23 is larger than the diameter of the nozzle outlet 9.
In this embodiment, the outer periphery of the core 10 is further provided with an annular upper positioning flange 13, and the upper end of the head cap 2 is provided with an annular lower positioning flange 22. After the spray head core 1 is inserted into the spray head cap 2, the core body 10 is matched and inserted into the spray head cavity 6, the upper positioning flange 13 is matched and pressed on the lower positioning flange 22, and the injection head 11 is matched and inserted into the column hole 20; at this time, the delivery channel 4 communicates with the nozzle cavity 6 through the slot 12, and the nozzle cavity 6 communicates with the nozzle outlet 9 through the rectangular slot 21, the cylindrical cavity section 80 and the inverted cone cavity section 81 in this order.

The working process comprises the following steps:
the dye liquor is injected from the nozzle inlet 3 under the pressure effect, then enters the nozzle cavity 6 through the 2 cavity injection openings 5, then enters the cyclone chamber 8 along the tangential direction through the 4 cyclone inlets 7 to form cyclone, and moves at high speed along the inner wall of the conical cyclone chamber 8 under the centrifugal force effect, because the reverse conical structure is adopted below the cyclone chamber 8, when the dye liquor flows to the tail end of the cyclone chamber 8, the dye liquor can obtain larger axial speed and radial speed, so the dye liquor can be sprayed out in the form of a conical liquid film at the nozzle outlet 9, and the high-speed liquid film moves relatively with air, tears and breaks into fine fog drops.
The spray angle of the dye solution sprayed from the spray outlet 9 is related to the space region of the spray field and the distribution of the fog drops, and the dye solution is diffused into an approximately conical spray form after being sprayed from the spray outlet 9, and the height of the spray outlet 9 from the smear can be calculated according to the size of the region to be dyed of the smear by measuring the spray angle, so that spray dyeing according to the required region size can be ensured. Wherein, the atomizing angle is the cone angle of a cone formed by diffusion after the dye liquor is sprayed out from the nozzle outlet 9, and the cone angle is as follows: the angle between two generatrices of the axial section of the cone (the section of the axis passing through the cone); the atomizing field is the bottom surface of the cone, i.e., the spray-dyed area.
In a preferred embodiment, the step of staining the smear with the device comprises:
1) Pre-measuring the injection pressure of the dye liquor to be P 0 The atomizing angle of the dye liquor sprayed from the nozzle outlet 9 is the cone angle of a cone formed by diffusion of the dye liquor after sprayed from the nozzle outlet 9;
2) Referring to FIG. 7, a minimum circle O is determined that completely covers the area to be stained on the smear min Is calculated from the center of the shower nozzle outlet 9 to the minimum circle O according to the following formula min Perpendicular distance h between the centers of circles:
3) To make the nozzle outlet 9 at the minimum circle O min H above the center of the circle of (C) and the pressure is P 0 And (3) injecting a dye solution into the nozzle inlet 3 to dye the smear.
For example, in one embodiment, images of the atomization angle under the conditions of the dye liquor injection pressure of 0.1, 0.12, 0.14, 0.16, 0.18, 0.2, 0.22 and 0.24MPa are acquired, corresponding atomization angles are measured, in order to reduce measurement errors, the size of the atomization angles is accurately estimated, five images are respectively taken for measurement at each test pressure, and an average value is taken; angular measurements were made by ImageJ software and with reference to fig. 8, it can be seen that the spray angle of the spray head increased from 56.72 ° to 77.17 ° as the injection pressure increased gradually from 0.1MPa to 0.24 MPa. When the injection pressure reaches 0.2MPa, the atomization angle is finally stabilized between 76 DEG and 78 deg. From the above data, it was found that the minimum distance parameter between the smear and the showerhead was between 34 and 51mm within the selected pressure range of 0.1-0.24 MPa.
In a further embodiment, the device is applied to blood smear staining and compared to artificial drip staining effects. Specifically, two smears were subjected to Rui-Jim Sa spray staining (using the apparatus of the present invention) and conventional manual drip staining, respectively. The parameters of spray-dyeing are that a smear is placed under a spray nozzle for 35mm, the injection pressure is 0.2MPa, and blood cells after dyeing, washing and drying are observed under a microscope as shown in fig. 9 (a), so that the nuclei are purplish red, the nuclear chromatin structure is clear, and a better dyeing effect is achieved. Compared with the manual drop dyeing of fig. 9 (b), the spray dyeing of fig. 9 (a) has higher spray dyeing efficiency, more uniform dyeing and lighter background color, and is beneficial to subsequent operations of identification, classification, counting and the like.
It will be appreciated that the device of the present invention is also applicable to smear staining of microorganisms and other pathogens.
