The same reference numerals in the drawings denote the same or similar structures, and thus a repetitive description thereof will be omitted.

The words expressing the positions and directions described in the present invention are described by taking the drawings as an example, but can be changed according to the needs, and all the changes are included in the protection scope of the present invention.

Referring to fig. 1, the present invention discloses an integrated nozzle structure comprising a nozzle body 1 and a chip 2.

The nozzle body 1 has a substantially cylindrical structure, and is provided with a fluid channel 12 for delivering a liquid. Typically, the fluid channel 12 is centrally located within the nozzle body 1 and extends through both ends along the length of the nozzle body 1.

In addition, one end of the nozzle body 1 is provided with a nozzle 11 communicating with the fluid channel 12, and the cross section of the nozzle is approximately trapezoidal, so as to provide a certain mist (corresponding to setting of a deflection angle) for atomized liquid drops sprayed from the nozzle 11, thereby facilitating absorption of patients and improving atomization quality.

The chip 2 is of a rectangular structure, and has the function of decomposing liquid into fine liquid drops for atomization, and also has the function of filtering. The chip 2 is disposed in the fluid channel 12 and is heat-sealed and fixed with the nozzle body 1. Under the action of pressure, the liquid input into the fluid channel 12 is atomized by the chip 2 and then can be sprayed out from the nozzle 11 to form atomized liquid drops.

Compared with the existing nozzle structure, the integrated nozzle structure omits a chip bracket and other accessory materials, and reduces the production cost. In addition, the chip 2 and the nozzle main body 1 are directly fixed in a heat sealing manner in the assembly process, the assembly mode is simple and efficient, the automatic assembly difficulty is greatly reduced, the production efficiency of products is obviously improved, and meanwhile, the sealing property and the stability between the chip 2 and the nozzle main body 1 are reliably ensured by the assembly mode of heat sealing.

Also as shown in fig. 1, in some embodiments, the unitary nozzle structure further comprises a pre-filter 3, the pre-filter 3 being disposed on a side of the chip 2 remote from the spout 11 for filtering large particle size impurities.

Illustratively, the pre-filter 3 is a PE filter that has good chemical stability and mechanical strength and is not prone to hydration reactions, suitable for use as a front end filter for the chip 2. The filter precision of the pre-filter 3 is 0.1mm to 0.5mm, thereby ensuring the reliability of the pre-filter effect, and preferably the filter precision of the pre-filter 3 may be 0.1mm.

In a specific embodiment, the fluid channel 12 is provided with a first mounting groove 14 and a second mounting groove 15, respectively, as shown in fig. 5, the first mounting groove 14 and the second mounting groove 15 are formed by two hot pressing of the heating member 4 (heating plate), and the groove width of the first mounting groove 14 is smaller than the groove width of the second mounting groove 15. Wherein the chip 2 is arranged in a first mounting groove 14 and the pre-filter 3 is arranged in a second mounting groove 15.

In one embodiment, the nozzle body 1 is made of a thermoplastic material, such as ABS, PC, TPE, which is plastic after being heated and pressurized and is solidified and molded after being cooled. This allows the inner wall portion of the nozzle body 1 to be softened by heating and molded under pressure into the desired first mounting groove 14 and second mounting groove 15, thereby meeting the rapid assembly requirements of the chip 2, the pre-filter 3.

Further, grooves (not shown) are formed on the surface, which is contacted with the nozzle body 1, of the chip 2, and the grooves can enhance the bonding strength of the chip 2 and the nozzle body 1 and improve the mounting stability of the chip 2.

Referring to fig. 1, in some embodiments, the other end of the nozzle body 1 is provided with a flange 13, the flange 13 extending outwardly from the end rim of the nozzle body 1 to form an annular structure for assembly fit with a spray device. For example, as shown in fig. 7, the flange 13 may be fixed to the flow guiding member 6 of the spraying device by ultrasonic welding.

Referring to fig. 2-4, in some embodiments, the chip 2 includes a first layer 21, a second layer 22, and a multi-stage filter structure 23.

In the chip 2, the second plate 22 is disposed on the first plate 21, and an inlet 24 and an outlet 25 are formed at both ends of the chip 2, respectively, so that liquid can be introduced into the inside of the chip 2 through the inlet 24 and can be ejected from the outlet 25 after being converted into atomized droplets.

The multistage filtering structure 23 is arranged between the first layer plate 21 and the second layer plate 22, and the multistage filtering structure 23 comprises a first microstructure filtering unit 231, a second microstructure filtering unit 232 and a third microstructure filtering unit 233 which are sequentially arranged along the liquid flow direction, so that three-stage filtering of liquid is realized, and the size of sprayed atomized liquid drops is ensured to meet the treatment requirement.

It should be noted that, in the present application, the first microstructure filtering unit 231 and the second microstructure filtering unit 232 are integrally formed on the first layer 21, the third microstructure filtering unit 233 is integrally formed on the second layer 22, and a part of the third microstructure filtering unit is filled in a part of the second microstructure filtering unit 232. Through designing chip 2 to bilayer structure to prepare first micro-structure filter unit 231 and second micro-structure filter unit 232 on first plywood 21, prepare third micro-structure filter unit 233 on second plywood 22, with this avoid concentrated etching first micro-structure filter unit 231, second micro-structure filter unit 232 and third micro-structure filter unit 233 (if at one deck sculpture micro-structure pattern, the precision requirement is higher), thereby can reduce the precision requirement of multistage filtration structure 23, do benefit to the production manufacturing of chip 2.

In addition, the multi-stage filter structure 23 adopts a layered etching mode, the microstructure patterns on any one of the first layer plate 21 and the second layer plate 22 are bad, only the corresponding layer plate needs to be replaced, the fault tolerance is high, the chip 2 cannot be scrapped completely, and therefore the manufacturing cost is reduced.

In a specific embodiment, the first microstructure filtering unit 231 is formed by a plurality of ribs arranged at intervals, each rib can be arranged along a horizontal line, and the filtering precision of the first microstructure filtering unit 231 is less than or equal to 0.1mm. The second microstructure filtering unit 232 is formed by a plurality of protruding blocks arranged at intervals, each protruding block is arranged to form a corrugated structure, and the second microstructure filtering unit 232 is used for main filtering of the chip 2, and the filtering precision is smaller than or equal to 0.002mm. The third microstructure filtering unit 233 is formed by a plurality of closely arranged protrusions, each of which is filled between the second microstructure filtering unit 232 and the outlet 25, and the filtering precision of the third microstructure filtering unit 233 is less than or equal to 0.01mm.

Further, as shown in fig. 3, the end of the protrusion near the inlet 24 is provided with a tangential surface 2311, and the tangential surface 2311 may be an inclined surface or an arc surface, and the tangential surface 2311 may change the flow direction of the liquid impinging on the protrusion into an inclined angle, thereby greatly reducing the turbulence generated when the liquid impinges on the inlet 24, and improving the filtering effect of the first microstructure filtering unit 231.

Referring to fig. 4, in some embodiments, a plurality of clamping blocks 26 are disposed at intervals on the edge of the first layer 21, a plurality of clamping grooves 27 are disposed at intervals on the edge of the second layer 22, and illustratively, four clamping blocks 26 are disposed at four corners of the first layer 21 respectively, and similarly, four clamping grooves 27 are disposed at four corners of the second layer 22 respectively, and the clamping blocks 26 are in one-to-one correspondence and match with the clamping grooves 27, so that the first layer 21 and the second layer 22 can be mutually clamped and fixed, and the assembly of the chip 2 is completed.

Referring to fig. 2, in some embodiments, the number of outlets 25 is two, with two outlets 25 being symmetrically disposed about the centerline of the chip 2, and the dual outlet 25 design may provide a larger atomization area so that the liquid can be sufficiently atomized and form more smaller atomized droplets.

Moreover, the included angle a28 formed by the extension lines of the jet directions of the two outlets 25 is an obtuse angle, so that the two jet directions are relatively dispersed, and the sprayed atomized liquid drops can be dispersed and mixed in a longer distance, so that a larger and more uniform atomization range is formed, the spraying coverage rate is improved, the atomized liquid drops can be more uniformly distributed in the whole spraying area, and a better atomization effect is achieved. In addition, the included angle a28 of the obtuse angle can also reduce the mutual interference and collision of atomized liquid drops in the spraying process, reduce the aggregation phenomenon among the atomized liquid drops, and further refine the size of the atomized liquid drops, thereby improving the quality effect.

Illustratively, the included angle a28 is greater than 90 degrees and less than or equal to 120 degrees, and in the obtuse angle range, the coverage effect of atomized liquid drops is uniform and comprehensive.

Referring to fig. 5 and 6, the invention also discloses an assembling method of the integrated nozzle structure, which comprises the following steps S1 to S3.

S1, providing a nozzle body 1 with a nozzle 11 and a fluid channel 12;

s2, assembling the chip 2 at a corresponding position of the fluid channel 12 in the nozzle main body 1;

s3, heating the nozzle body 1 so as to fix the chip 2 and the nozzle body 1 in a heat sealing manner.

Specifically, as shown in fig. 5, in one embodiment, the nozzle body 1 is made of thermoplastic material, and in addition, in step S3, a heating member 4 is disposed on a side of the chip 2 away from the nozzle 11 (it should be noted that, in this process, the heating member 4 is a heating plate, and the cross section of the heating plate is slightly larger than the diameter surface of the fluid cavity 12, so as to completely cover the fluid cavity 12, and the heating plate will be described below as an example), and the heating member 4 presses and thermally melts a portion of the nozzle body 1 to thermally encapsulate the bottom of the chip 2.

In the assembly process, after the chip 2 is installed in the fluid channel 12 in the nozzle body 1, the top of the chip can be tightly propped and limited at the nozzle 11, then the heating plate enters the fluid channel 12 from one end of the nozzle body 1 far away from the nozzle 11, the heating plate heats part of the inner wall of the nozzle body 1, so that the inner wall is softened and deformed under the action of pressure, a step structure is formed at the bottom of the chip 2, the chip 2 is fixed and sealed in a first mounting groove 14 formed by the limiting position of the nozzle 11 and the step structure, and finally the heating plate is withdrawn from the fluid channel 12, so that the chip 2 and the nozzle form an integrated structure.

In the above process, the heating temperature of the heating member 4 is 70 ℃ to 100 ℃, if the heating temperature is lower than 70 ℃, the inside of the nozzle body 1 is not thoroughly softened, the step structure cannot be effectively molded, and if the heating temperature is higher than 100 ℃, the aging of the material is accelerated, and the performance of the nozzle body 1 is affected. In addition, the pressing pressure of the heating member 4 is 50N to 70N, and if the pressing pressure is less than 50N, it is difficult to push the softened material to form a stepped structure, and if the pressing pressure is more than 70N, it is easy to damage the precision chip 2, and the atomization effect is affected.

Illustratively, the heating element 4 has a heating temperature of 78 ℃ and an extrusion pressure of 65N for the heating element 4; the heating temperature of the heating element 4 may be 85 ℃, the pressing pressure of the heating element 4 may be 60N, or the like.

In another embodiment, as shown in fig. 6, the nozzle body 1 is made of a metal material, such as copper, aluminum alloy, and the like, and the thermoplastic material layer 5 is disposed in the fluid channel 12, and the thermoplastic material layer 5 may be an ABS layer, a PC layer, a TPE layer, or the like. In addition, in step S3, a heating element 4 (the heating element 4 may be a heating plate, a heating coil, or the like) is disposed in a sidewall of the nozzle body 1, and the heating element 4 thermally melts the thermoplastic material layer 5 through the nozzle body 1 to thermally encapsulate the entire body of the chip 2.

In this assembly process, after the chip 2 is mounted in the fluid channel 12 in the nozzle body 1, only the heating element 4 built in the sidewall of the nozzle body 1 needs to be directly electrified (the electrical contact point of the heating element 4 is disposed on the nozzle body 1, not shown), and the heat of the heating element 4 is transferred to the thermoplastic material layer 5 through the nozzle body 1, so that the thermoplastic material layer 5 and the whole body of the chip 2 are fixed by hot melting, and the chip 2 and the nozzle form an integral structure.

The chip 2 and the nozzle main body 1 are fixed in a heat sealing manner, the assembly mode is simple and efficient, the automatic assembly difficulty is greatly reduced, the production efficiency of the product is obviously improved, and meanwhile, the tightness and stability between the chip 2 and the nozzle main body 1 are reliably ensured in the heat sealing assembly mode.

The second assembly method, among others, omits the step of moving the heating member 4, and is higher in assembly efficiency than the first assembly method. However, the mounting reliability of the chip 2 is improved by forming the mounting groove by extrusion in one assembly method, and the heating member 4 can be reused, so that the production cost is lower.

In some embodiments, the following steps S4 to S5 are further included.

S4, assembling the prefilter 3 at a corresponding position of the fluid channel 12 in the nozzle body 1;

s5, heating the nozzle body 1 so as to fix the prefilter 3 and the nozzle body 1 in a heat sealing manner.

The assembly process of the pre-filter 3 is the same as the assembly process of the chip 2, and any of the above two methods may be used, and will not be described here. By installing the pre-filter 3 in the fluid channel 12, large-particle-size impurities can be prevented from entering the chip 2, and the service life and atomization effect of the chip 2 are ensured.

Referring to fig. 7, the invention also discloses an atomization device, which comprises the integrated nozzle structure, so that the atomization device can be well adapted to automatic assembly, and the production cost of products is effectively reduced.

While embodiments of the present invention have been shown and described, it will be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that changes, modifications, substitutions and alterations may be made therein by those of ordinary skill in the art without departing from the spirit and scope of the invention, all such changes being within the scope of the appended claims.
