Detailed description of the invention

In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Please refer to accompanying drawing 2-7, wherein, Fig. 2 provides by the utility model the sectional view of the first detailed description of the invention of capping; Fig. 3 is the top view of Fig. 2; Fig. 4 provides by the utility model the sectional view of the second detailed description of the invention of capping; Fig. 5 is the top view of Fig. 4; Fig. 6 is the upward view of Fig. 4; Fig. 7 provides by the utility model the sectional view of insulator.

In a kind of detailed description of the invention, the utility model provides a kind of capping 11 of insulator 1, and wherein, this insulator 1 comprises insulator body 12 and is located at the capping 11 at its top, capping 11 has the venthole 111 be communicated with insulator body 12 open top, and this venthole 111 is annular.

In cathode hanger insulator 1 ＇ shown in Fig. 1, cover plate 11 ＇ is provided with venthole 111 ＇, when air enters from this venthole 111 ＇, the whole inwall of insulator body 12 ＇ can not be covered, thus make purge there is dead angle, purging effect is poor, and this cathode hanger insulator 1 ＇ creepage punch-through easily occurs and damages.

And in the present embodiment, air enters insulator body 12 inside by annular venthole 111, and this annular venthole 111 makes the air entering insulator body 12 inside cover the whole inwall of insulator body 1, and purge is without dead angle, improve and purge effect, thus improve the service life of equipment.

Particularly, as shown in figures 2-6, capping 11 is the structure of inner hollow, and annular venthole 111 is located at the diapire of capping 11, the diapire of capping 11 is connected by contiguous block 114 with between roof, prevents the base plate of perforate rear seal-cover 11 from dropping, thus ensures the integrality of capping 11.In addition, this capping 11 also comprises air admission hole 112, and first air enters the internal cavities 113 of capping 11 by this air admission hole 112, then, enters in insulator body 12, purge the inwall of insulator body 12 by venthole 111.

In the present embodiment, first air collects at the internal cavities 113 of capping 11, thus improves the uniformity of air, improves and purges effect.In addition, the sectional area due to internal cavities 113 is greater than the area of venthole 111, when air enters insulator body 12 from internal cavities 113 by venthole 111, can improve the flow velocity of air, thus improves purging effect further.

Further, in the embodiment shown in Fig. 2 and Fig. 3,4 air admission holes 112 are evenly located at the sidewall of capping 11.In embodiment shown in Fig. 4-6,4 air admission holes 112 are evenly located at the roof of capping 11.

It should be noted that, setting position and the number of air admission hole 112 are not limited in this, also can set as required, only need air to be passed into internal cavities 113.Therefore, the structure of air admission hole 112, setting position and concrete number are not construed as limiting the technical scheme of the application's request protection.

Further, capping 11 is concentric cylindrical structure with contiguous block 114, and the internal cavities 113 of capping 11 is divided into annular by the contiguous block 114 of this cylindrical structure.

Certainly, capping 11 and contiguous block 114 are not be necessary for cylinder, can be arbitrary shape, such as rectangular shape etc. yet.But in the present embodiment, when contiguous block 114 and capping 11 are cylindrical structure, internal cavities 113 is toroidal cavity, the effect of guiding air can be played, thus enter insulator body 12 with making smooth air.

In addition, as shown in Figure 7, electric cleaner also comprises suspension rod 2, suspension rod 2 is through the installing hole of capping 11, contiguous block 114 and insulator body 12, and fix with three, this installing hole is through the center line of three, and the two ends of suspension rod 2 are connected with deduster respectively, thus makes insulator 1 be hung on deduster by suspension rod 2.

Above in each embodiment, as shown in Figure 7, the sidewall of venthole 111 is mutually concordant with the open-topped sidewall of insulator body 12, thus ensure further air from venthole 111 enter insulator body 12 purge time, purge without dead angle.

The utility model also provides a kind of insulator 1 of deduster, and comprise insulator body 12 and be located at the capping 11 at its top, wherein, capping 11 is the capping 11 described in above any embodiment.Because this capping 11 has above-mentioned technique effect, the insulator 1 comprising this capping 11 also has identical technique effect, repeats no more herein.

Above a kind of insulator provided by the utility model and capping thereof are all described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
