Example 1

With reference to fig. 1-5, this embodiment provides a rain hat comprising:

a first cone 1, the first cone 1 having a first bottom face 11 and a first side face 15;

A second cone 2, the second cone 2 having a second bottom surface 21 and a second side surface 24;

a mounting seat 4 connected with the second side 24 of the second cone 2;

The first bottom surface 11 is connected with the second bottom surface 21, and the second cone 2 is closer to the mounting seat 4 than the first cone 1 along the height direction of the rain cap, wherein the first bottom surface 11 is connected with the second bottom surface 21, and the first bottom surface 11 covers the second bottom surface 21, so that the second cone 2 plays a role in guiding oil smoke, and the oil smoke from the exhaust pipe 7 can be well discharged to the outside; and since the first bottom surface 11 covers the second bottom surface 21, rainwater passing through the first side surface 15 of the first cone 1 drops at the end of the first side surface 15 without flowing into the exhaust pipe 7 along the second side surface 24.

In particular, the first cone 1 is used for rain protection, and the first side 15 of the first cone 1 may be slightly convex or concave, or may be flat, preferably flat, i.e. the first cone 1 is preferably conical; the first side 15 is used for shielding rainwater and generating a diversion effect on the rainwater so that the rainwater flows along the first side 15; the second cone 2 is used for dispelling wind and guiding oil, and the second side 24 of the second cone 2 can be slightly convex or concave, or can be flat, preferably flat, i.e. the second cone 2 is preferably conical; the second side surface 24 is used for guiding the oil fume from the exhaust pipe 7, so that the oil fume is discharged smoothly, meanwhile, the oil stains remained on the wall of the second side surface 24 are collected to the center of the second side surface 24, and the oil stains in the collected oil fume can drop into the exhaust pipe 7 to prevent the oil stains in the oil fume from dropping out of the exhaust pipe 7 and on the outer wall 8; the mounting seat 4 is used for connecting the second side 24 of the second cone 2 to the exhaust pipe 7, so that the rain-proof cap is connected to the exhaust pipe 7; the first bottom surface 11 covers the second bottom surface 21, so that rainwater flowing along the first side surface 15 directly drops under the action of gravity, the rainwater is effectively prevented from sequentially along the first side surface 15 and the second side surface 24, and finally enters the exhaust pipe 7, and the rainwater-proof performance of the rain hat is ensured.

Further, as shown in fig. 3, the central axis 13 of the first cone 1 and the central axis 13 of the second cone 2 are coaxially arranged, wherein the coaxiality within the allowable error range is regarded as coaxiality, so that the first cone 1 and the second cone 2 have good installation symmetry, and therefore the first cone 1 and the second cone 2 have good stress symmetry, and the installation firmness of the rain hat is ensured.

Further, as shown in fig. 4, the adaptor 3 is further comprised between the first bottom surface 11 and the second bottom surface 21, the portion of the first bottom surface 11 located outside the adaptor 3 is configured as a first outer bottom surface 12, and the height of the first outer bottom surface 12 gradually decreases in the inside-to-outside direction of the adaptor 3; the portion of the second bottom surface 21 located outside the adapter 3 is configured as a second outer bottom surface 22, and the height of the second outer bottom surface 22 gradually decreases in the inward-to-outward direction of the adapter 3.

Specifically, since the height of the first outer bottom surface 12 gradually decreases in the inward-outward direction of the adapter 3, it is convenient to prevent rainwater from flowing along the first side surface 15 and the first outer bottom surface 12 to the second outer bottom surface 22 under the action of viscosity and tension thereof; the height of the second outer bottom surface 22 gradually decreases in the inside-to-outside direction of the adapter 3, so that rainwater is prevented from flowing into the exhaust pipe 7 along the second outer bottom surface 22 and the second side surface 24 under the action of viscosity and tension thereof, thereby ensuring good rainwater-proof performance of the rain-proof cap.

Further, as shown in FIG. 4, the area surrounded by the first outer bottom surface 12, the adapter 3, and the second outer bottom surface 22 is configured to accommodate the cavity 5.

Specifically, the accommodation chamber 5 serves to accommodate rainwater and to increase a path through which the rainwater flows, thereby making it difficult for the rainwater to flow into the exhaust pipe 7.

Further, as shown in fig. 3 and 5, the mount 4 includes:

A base 41;

And a plurality of struts 42, wherein one ends of the struts 42 are connected with the second side 24, and the other ends of the struts 42 are connected with the base 41.

Specifically, the base 41 is configured to bear the second side 24 of the second cone 2 through the plurality of struts 42, so as to prevent the distance between the base 41 and the second cone 2 from being too close, thereby preventing the base 41 from adversely affecting the wind-dispelling and oil-guiding performance of the second side 24 of the second cone 2.

Further, as shown in fig. 3 and 5, a plurality of struts 42 are uniformly distributed along the circumference of the second side 24.

The stress symmetry of the second cone 2 is facilitated to be increased, thereby facilitating the assurance of the stability of the second cone 2.

Further, as shown in fig. 3, the first cone 1 has a cavity 14 inside, and the weight of the first cone 1 is smaller than the weight of the second cone 2.

In particular, the cavity 14 facilitates reducing the weight of the first cone 1, and since the weight of the first cone 1 is smaller than the weight of the second cone 2, facilitates enabling the rain-proof cap to achieve a light-up and heavy-down condition, thereby facilitating increasing the stability of the rain-proof cap.

1-5, This embodiment also provides an exhaust system comprising a rain hat of embodiment 1, further comprising:

the exhaust pipe 7 is connected with the mounting seat 4;

wherein the first bottom surface 11 covers the outlet of the exhaust pipe 7, so that rainwater flows out of the exhaust pipe 7 under the action of gravity after passing through the rain cap.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
