Description
Technical Field
The present invention relates to a cleaning machine.
Background
The motor drives the swash plate to rotate through the speed reducing mechanism, the swash plate drives the plurality of circumferentially distributed plungers to sequentially lift, the sequentially lifted plungers pump liquid into the liquid cavity through the water inlet pipeline and then discharge the liquid at high pressure, and the high-pressure liquid is sprayed to a cleaning object through the water outlet pipe and the spray heads on the water outlet pipe.
The speed reducing mechanism and the sloping cam plate driven by the motor are arranged in a sealed chamber, and the chamber is filled with liquid oil which cools and lubricates the speed reducing mechanism and the sloping cam plate. According to the prior art, the pump body forming the chamber is a regular cylindrical piece.
The utility model has the following contents:
the technical problems solved by the utility model are as follows: a light-weight and small-sized high-pressure cleaning machine.
In order to solve the technical problems, the utility model provides the following technical scheme: the special-shaped pump body is internally provided with a speed reducing mechanism and a swash plate and is applied to a high-pressure cleaning machine, the top of the special-shaped pump body is of an irregular disc-shaped structure, the disc-shaped structure is provided with a radial inward-contracting part, and the radial inward-contracting part is positioned between two adjacent plungers.
The utility model improves the shape of the pump body in the prior art, the bottom part keeps the original shape, and the top part is in a special shape, namely the irregular disk-shaped structure. The disc-shaped structure can accommodate a plurality of plungers, a certain gap is kept between the inner wall of the disc-shaped structure and the plungers, the free work of the plurality of plungers in the disc-shaped structure needs to be ensured while the periphery of the disc-shaped structure is reduced as much as possible, and therefore, the radial inward-contracting part is designed to ensure that the periphery of the disc-shaped structure is reduced as much as possible while the free work of the plurality of plungers in the disc-shaped structure is ensured.
The bottom of the special-shaped pump body is of a circular structure, the top of the special-shaped pump body is of an irregular disk-shaped structure, and the side wall of the special-shaped pump body is smoothly connected with the bottom end and the top end of the special-shaped pump body. Compared with the regular cylindrical part in the prior art, the special-shaped pump body designed by the utility model has the advantage of reduced volume, which is beneficial to the light weight and miniaturization of the high-pressure cleaning machine.
Description of the drawings:
FIG. 1 is a schematic view of a contoured pump body;
FIG. 2 is a schematic view of the main body 20 of FIG. 1 after being hidden;
FIG. 3 is a top view of FIG. 1;
FIG. 4 is a cross-sectional view A-A of FIG. 1;
fig. 5 is a bottom view of fig. 1.
The symbols in the drawings illustrate that:
10. a disc-shaped structure; 11. a radially inwardly tapered portion; 12. connecting hole sites; 13. a convex portion; 14. a connecting lug;
20. a main body; 21. a guide member;
30. a lower end cover;
41. a speed reduction mechanism; 42. a swash plate; 43. and a plunger.
The specific implementation mode is as follows:
referring to fig. 1 to 5, the high pressure cleaner has a shaped pump body in which a speed reduction mechanism 41 and a swash plate 42 are provided, the bottom of the shaped pump body having a circular structure 30, and the top of the shaped pump body having an irregular disk structure 10 having at most (at most) radially inwardly recessed portions 11 equal in number to the number of plungers. The design of the radially inwardly tapered portion is a result of the reduced disc-like structure and the assurance that the plunger is free to operate within the pump body. For example, when the high-pressure washer employs a three-plunger pump, the number of the plungers is three, and accordingly, the number of the radially-retracted portions is three, and the three portions are respectively located between two adjacent plungers.
The top of the special-shaped pump body is connected with a shell of the formed liquid cavity, a plunger 43 penetrates through the disc-shaped structure 10, the bottom end of the plunger is abutted against the swash plate 42, and the top of the plunger extends into the liquid cavity. Thus, as shown in fig. 3, the disc-shaped structure 10 is provided with a number of connection holes 12 in connection with the housing of the formed liquid chamber, which connection holes are provided on the protrusions 13. For example, if the housing of the molded liquid chamber is mounted on the top of the profile pump body by three connecting pieces, the number of the projections 13 is three.
As a structural choice, the special-shaped pump body can be an integral structural part or a split structural part.
With reference to fig. 1 and 2, if the special-shaped pump body is designed into a split structure, the special-shaped pump body comprises a guide member 21, a main body 20 and a lower end cover 30, the guide member is a disc-shaped structure 10, the lower end cover is a circular structure, and the guide member is connected with the main body and the lower end cover through a plurality of connecting members. The top of the body and the guide are provided with a number of attachment lugs 14 equal to the number of attachment elements, as shown in figure 3. For example, the guide is provided with four connecting lugs, the top of the main body is provided with four matching connecting lugs, the lower end cover is provided with four matching connecting lugs, and the connecting piece is connected with the guide, the main body and the lower end cover through the matching connecting lugs. Wherein the top of the main body 20 and the connecting lug of the guide 21 are located at the radially inwardly contracted portion 11 to achieve the object of weight reduction and miniaturization of the high pressure washer.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
