Abstract
The utility model relates to a cylinder head of a small oil-less air compressor. The cylinder head comprises a high-pressure chamber and a low-pressure chamber which are arranged on the bottom of the cylinder head, the high-pressure chamber is connected with an exhaust tube on the side of the cylinder head, the lower-pressure chamber is connected with an intake tube on the side of the cylinder head, and limiting posts for limiting the opening angle of an exhaust valve plate on a valve plate assembly is arranged in the high-pressure chamber, and are integrated with the cylinder head. Since the cylinder head comprises the limiting posts for limiting the opening angle of the exhaust valve plate on the valve plate assembly, related units arranged on the matched valve plate assembly are dispensed with, so that the structure of the valve plate is simplified, and moreover, the reliability of the integrated limiting posts is higher than the reliability of additionally mounted independent parts as well.
Description
Technical field
The utility model relates to a kind of oil-free air compressor, particularly a kind of small-sized oil-free air compressor cylinder head.
Background technique
Oil-free air compressor has been cancelled the oil lubrication device in the common air compressor, produces clean oil-free compressed air, thereby has obtained using widely in some special dimension.When oil-free air compressor commonly used is worked, motor drives piston ring to-and-fro motion in cylinder by transmission device, realize compressed-air actuated function, wherein compressor cylinder cover is connected the inlet and outlet control that realizes compressor with the air valve plate, and reaches the effect of sealing cylinder.But current small-sized oil-free air compressor cylinder head exists the design and installation complexity, reliability is not high and fail to satisfy some problems of compressor miniaturization requirement, like this, the structure of improvement oil-free air compressor cylinder head has just become the design focal point of current oil-free air compressor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel structure, and is simple and reliable, and can satisfy the cylinder head of oil-free air compressor miniaturization requirement.
The technical solution adopted in the utility model can be described as:
A kind of small-sized oil-free air compressor cylinder head, it comprises hyperbaric chamber and the low-pressure cavity that is arranged on the cylinder head bottom, described hyperbaric chamber links to each other with the outlet pipe of cylinder head side, low-pressure cavity links to each other with the suction tude of cylinder head side, is provided with in also at hyperbaric chamber to be used to limit the limited post of opening angle of valve block of giving vent to anger on the air valve board component.
As the further improvement of above technological scheme, described limited post and cylinder head are one-body molded.
The beneficial effects of the utility model are:
The cylinder head that the utility model proposes includes the integrated limited post of opening angle of valve block of giving vent to anger on the air valve board component that is used to limit, not only removed from matching used air valve board component relevant apparatus has been set, simplified the structure of air valve plate, and integrated limited post also surpasses the extra independent part of installing on reliability.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the B-B sectional view of Fig. 2.
Embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of small-sized oil-free air compressor cylinder head, it comprises hyperbaric chamber 1 and the low-pressure cavity 2 that is arranged on the cylinder head bottom, described hyperbaric chamber 1 links to each other with the outlet pipe 11 of cylinder head side, low-pressure cavity 2 links to each other with the suction tude 21 of cylinder head side, be provided with in the described hyperbaric chamber 1 and be used to limit the limited post 12 of opening angle of valve block of giving vent to anger on the air valve board component, this limited post 12 is one-body molded with cylinder head, this has not only exempted on matching used air valve board component relevant apparatus has been set, simplified the structure of air valve board component, and integrated limited post also surpasses the extra independent part of installing on reliability.
Limited post 12 tops are outward-dipping plane, and this is the air valve plate opened of support well, reduce the stress that air valve plate is subjected to.
The bottom of cylinder head also is provided with circular orientation pin 3 along the screw hole outer, can reduce the loading error between cylinder head and the air valve board component like this when compressor assembles effectively.
For strengthening the intensity and the heat radiation of cylinder head, be equipped with stiffening rib 4 in hyperbaric chamber 1 and the low-pressure cavity 2, the cylinder head top is provided with along cooling air and flows to the radiating fin of arranging 6.
Sealing when assembling for strengthening cylinder head and air valve plate, the cylinder head bottom is provided with the potted line 5 of a circle projection along hyperbaric chamber 1 outside, and this potted line is pressed into cylinder head gasket during assembling, and its sealing effect far is better than the sealing means of employing face contact.
