Detailed Implementation

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0022] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0023] The following example describes a dispenser of this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without inventive effort should be covered within the protection scope of this utility model.

[0024] Please refer to the reference. Figures 1 to 5 According to Embodiment 1 of this utility model, a distributor is provided, including a distributor body, which includes an inlet section 1, a transition section 2, and an outlet section 3. The inlet section is provided with an inlet channel 11, and the distributor body is integrally formed. A transition section 2 with a variable diameter is provided between the inlet section 1 and the outlet section 3, and the interior of the transition section is a cavity structure. The outlet section is generally cylindrical, and two outlet holes 31 are evenly distributed along the circumference of the outlet section. A spun flow throttling section 4 is provided between the inlet section and the transition section, and a flow divider cone 5 is protruding from the inner end face of the outlet section.

[0025] Four recessed portions 32 are formed by partial indentation between adjacent outlet holes in the liquid outlet section. These recessed portions only penetrate the outer end face 33 of the liquid outlet section and retain the ribs 36 that form the circumferential surface of the liquid outlet section. This partial indentation between adjacent outlet holes reduces the material used in the distributor body, lowering the distributor cost. Furthermore, by forming only partial recesses, the circumferential surface 34 of the liquid outlet section is retained in the axial height of the recessed portions, and the ribs 36 also retain their circumferential surfaces 34. Since the recessed portions only penetrate the outer end face of the liquid outlet section, a portion of the complete circumferential surface is preserved, facilitating the machining of the transition section and the liquid inlet section after clamping. The distributor body can be integrally formed by extrusion to create the recessed portions without increasing costs.

[0026] In this embodiment, the distance H between the axial bottom surface 321 of the concave portion and the inner end face 35 of the liquid outlet portion is greater than or equal to the wall thickness L of the transition portion. The axial bottom surface 321 of the concave portion and the radial concave surface 322 of the liquid outlet portion have a smooth transition, ensuring the strength and rigidity of the liquid outlet portion and reducing the deformation of the liquid outlet portion when clamped by the fixture, thereby ensuring the machining quality of the transition portion and the liquid inlet portion. It is recommended that H be no less than 1.5 mm, preferably more than 2 mm, and L be no less than 1 mm.

[0027] The concave portion's axial projection is a 323-shaped, uniform-diameter circular arc, which smoothly transitions with the circumference of the liquid outlet portion. The fillet radius between the uniform-diameter circular arc and the circumference of the liquid outlet portion is no greater than 1.5mm, and a longer circumferential surface of the liquid outlet portion is reserved as much as possible to increase the clamping surface of the fixture. In addition, the uniform-diameter circular arc shape can also be used for clamping with tooling. The tooling corresponding to the uniform-diameter circular arc is also a uniform-diameter circular arc, which facilitates the machining of the tooling.

[0028] In addition, the ratio of the minimum distance 'a' between the inner wall surface of the liquid outlet and the circumferential surface of the liquid outlet to the minimum distance 'b' between the inner wall surface of the liquid outlet and the wall surface of the concave portion is between 0.8 and 1.2. This small difference in wall thickness ensures the strength and rigidity of the liquid outlet and prevents deformation of the liquid outlet during clamping. 'a' is generally not less than 1.5 mm, and 'b' is generally between 1.2 and 1.8 mm.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
