Description

Technical Field

[0001] The invention belongs to an electron gun filament locking structure and method, and in particular relates to a mosquito-repellent incense type filament structure. Background Art

[0002] The mosquito coil-type filament is a commonly used structure in electron gun devices. As a key emitting part of the electron gun device, its fast and reliable locking plays a very important role in ensuring the performance of the electron gun and the consistency of batch production of electron guns. And because the filament is a "wearing part", it needs to be replaced when the filament fails. The locking structure of the filament must be simple and convenient, and the assembly and disassembly must be quick. At the same time, the structure of the filament must be simple to reduce the filament processing procedures and reduce the processing cost of the filament.

[0003] The existing electron gun filament structure often cannot take into account both the simplicity of the filament structure and reliable clamping at the same time. When the clamping is reliable, the structure is often complicated, while when the structure is simple, the clamping is prone to failure. Summary of the invention

[0004] The object of the present invention is to provide a mosquito coil type filament structure to solve the technical problem that the existing electron gun filament structure cannot simultaneously meet the requirements of simple structure and reliable clamping.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A mosquito coil type filament structure comprises a filament fixing base and a filament, wherein a placement groove is formed on the top surface of the filament fixing base, the filament is arranged in the placement groove and fixed by a filament clamping block; the filament comprises an emitting disk and two supporting legs connected to the emitting disk, the two supporting legs are in the same horizontal plane and the angle between the two supporting legs is a non-acute angle.

[0007] In the above technical solution, the emission disk and the support legs of the filament are integrally formed, the emission disk is spirally wound to form a disc-shaped structure, the angle between the two support legs is 90° to 150°, and the design of the angle between the two support legs effectively improves the reliability of filament locking, avoiding the rotation of the filament of the traditional 180° support leg structure during operation, resulting in failure of filament locking.

[0008] In the above technical solution, the placement groove includes a central disc groove and two strip-shaped positioning grooves, the positioning groove is connected to the disc groove, and the angle of the central axis of the two positioning grooves is the same as the angle of the two supporting legs of the filament.

[0009] In the above technical solution, the width of the positioning groove is greater than 1.5 times the diameter of the filament, which is convenient for putting in and taking out the filament and for easy assembly and disassembly.

[0010] In the above technical solution, the filament clamping block is a convex structure, a through hole is formed on the shoulder, a clamping groove is formed on the bottom surface, and the bottom of the clamping groove is an arc shape.

[0011] In the above technical solution, the diameter of the clamping groove is larger than the diameter of the filament, so as to increase the contact area between the filament clamping block and the filament supporting leg and improve the clamping reliability.

[0012] In the above technical solution, a filament clamping block placement groove is formed on the top of the filament fixing base, the filament clamping block is arranged in the groove, and the filament clamping block and the filament clamping block placement groove are fastened by a locking screw.

[0013] In the above technical solution, the height of the filament clamping block should be slightly greater than the depth of the positioning groove on the filament fixing base to ensure that after the filament is clamped, the filament disk surface is as "closed" as possible to ensure the emission power of the filament.

[0014] In the above technical solution, the filament fixing base and the filament clamping block are both made of metal materials with excellent electrical conductivity and high temperature resistance to meet the requirements of high temperature working environment.

[0015] In the above technical solution, the locking screw is made of a high-temperature resistant material different from that of the filament fixing base and the filament clamping block to prevent the locking screw and the filament fixing base from sticking together at high temperatures when made of the same material, thereby facilitating the timed replacement of the filament, which is a consumable part of the electron gun.

[0016] The beneficial effects of the present invention are:

[0017] The invention provides a mosquito-repellent coil type filament structure with reliable and simple clamping. The filament structure is special, and the filament support legs are in the same horizontal plane and are 90° to 150°, which effectively simplifies the processing technology and structure of the filament and is conducive to reliable locking of the filament. The reliable locking of the filament is achieved by clamping the filament clamping block and the filament fixing base and the clamping groove with a special structure on the filament clamping block. Compared with other filament structures and locking methods, the invention realizes both the characteristics of simple filament structure and reliable locking. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1 As shown, a mosquito coil type filament structure with reliable and simple clamping includes a filament fixing base 1, a filament clamping block 2 and a filament 3, wherein the filament 3 is fixed on the filament fixing base 1 through the filament clamping block 2.

[0035] like Figure 2 As shown, the top surface of the filament fixing base 1 forms a placement groove for the filament 3 and two filament clamping block placement grooves, the placement groove includes a central disc groove 12 and two strip-shaped positioning grooves 11, one end of the positioning groove 11 is connected to the disc groove 12, and the other end is connected to the filament clamping block placement groove on the same side. The filament clamping block 2 is arranged in the filament clamping block placement groove, and the filament clamping block 2 is fastened to the filament clamping block placement groove by a locking screw 4.

[0036] like Figure 3 As shown, the filament clamping block 2 is a convex structure, with a through hole 22 formed on the shoulder and a clamping groove 21 formed on the bottom surface, and the bottom of the clamping groove 21 is arc-shaped. After the filament is placed in the placement groove, the filament clamping block 2 is placed in the filament clamping block placement groove, and the clamping groove 21 clamps the support leg 32 of the filament.

[0037] In this embodiment, the height of the filament clamping block 2 is greater than the depth of the positioning groove 11 on the filament fixing base 1 .

[0038] In this embodiment, the diameter of the clamping groove 21 is greater than the diameter of the filament 3 .

[0039] like Figure 4 , 5 As shown, the filament 3 includes an emitting disk 31 and two supporting legs 32 connected to the emitting disk 31, and the emitting disk 31 and the supporting legs 32 are integrally formed; the emitting disk 31 is spirally wound to form a disk-shaped structure; the supporting legs 32 only need to be bent once Figure 5 The L-shaped structure formed at the circle has one section connected to the launch disk 31 and one section used for locking; the two support legs 32 used for locking are in the same horizontal plane and the angle between them is 90° to 150°; the launch disk 31 is placed in the disc groove 12, and the support legs 32 used for locking are set in the positioning groove, so the angle of the central axis of the two positioning grooves 11 is the same as the angle of the two support legs of the filament 3, and the width of the positioning groove 11 is greater than 1.5 times the wire diameter of the filament 3, which is convenient for taking and placing. The special structure of the filament of the present invention is different from Figure 6 The conventional mosquito coil type filament structure shown in the figure has a conventional filament support leg which is initially 180° or 0° and needs to be bent and circled multiple times to obtain the following Figure 6 The supporting leg shape shown in FIG. 1 , while the supporting leg of the filament of the present invention only needs to be bent once, Figure 6 Compared with the filament shown in the figure, the structure is simpler and the processing and manufacturing process is also simpler.

[0040] In this embodiment, the filament fixing base 1 and the filament clamping block 2 are both made of conductive and high-temperature resistant metal materials.

[0041] In this embodiment, the locking screw 4 is made of a high temperature resistant material different from that of the filament fixing base 1 and the filament clamping block 2 .

[0042] The structures of the filament fixing base 1 and the filament clamping block 2 in the present invention can be adjusted according to actual use conditions on the basis of meeting the above requirements.

[0043] The installation process of the present invention:

[0044] First, fix the filament fixing base 1 on the installation position of the electron gun to ensure that the filament fixing base 1 is reliably fixed; put the two supporting legs 32 of the filament 3 into the two positioning grooves 11 of the filament fixing base 1 respectively, visually adjust the positions of the two supporting legs 32 of the filament 3 in the positioning grooves 11, and visually check that the supporting legs 32 are located at the center of the positioning grooves 11; put in the filament clamping block 2, ensure that the clamping grooves 21 on the filament clamping block 2 are respectively inserted into the supporting legs 32 of the filament 3, adjust the position of the filament clamping block 2, and ensure that the two through holes on the filament clamping block 2 correspond to the positions of the two threaded holes on the filament fixing base 1; install the locking screw 4, fine-tune the position of the filament clamping block 2, and when the two supporting legs of the filament 3 are respectively located at the center positions of the corresponding positioning grooves 11, tighten the locking screw 4 to complete the clamping of the filament 3; when replacing the filament 3, it is only necessary to loosen the locking screw 4 and take out the filament clamping block 2 to complete the replacement of the filament 3.

[0045] The invention discloses a mosquito-repellent incense type filament structure with reliable and simple clamping, wherein the supporting legs only need to be bent once, and compared with other filaments which need to be bent multiple times to improve the locking reliability, the processing technology is simpler.
