[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides Figure 1-3 A structure for avoiding interference between a feeding quartz tube and the lower edge of a sub-chamber is shown, comprising a sub-chamber body 1 and a quartz tube body 8 installed at the lower side of the sub-chamber body 1;
[0021] The lower side of the auxiliary chamber body 1 is provided with a flange interface a4 which is sleeved on the quartz tube body 8;
[0022] The lower end outer wall of the auxiliary chamber body 1 is provided with a through opening 2 opening downwards;
[0023] The upper outer wall of the flange interface a4 is equidistantly fixedly connected with a plurality of magnetic plates a9, and the circular inner wall of the through opening 2 is equidistantly fixedly connected with a plurality of magnetic plates b10. When the feeding quartz tube body 8 moves upward into the interior of the sub-chamber body 1, the magnetic plates a9 of the feeding quartz tube body 8 and the magnetic plates b10 on the inner wall of the through opening 2 at the lower edge of the sub-chamber body 1 repel each other with the same polarity. The quartz feeder will maintain a certain distance from the lower edge of the sub-chamber body 1 without contact, so that no contact will occur and interference will be avoided.
[0024] like Figure 2 As shown, multiple magnetic plates a9 and magnetic plates b10 repel each other with the same polarity, the lateral length of the spacing between multiple magnetic plates b10 is the same as the lateral length of magnetic plate a9, the lateral length of magnetic plate a9 is smaller than the lateral length of magnetic plate b10, and the vertical length of magnetic plate a9 is larger than the vertical length of magnetic plate b10 to increase the speed of repulsion between the two.
[0025] Magnetic plates a9 and b10 with the same polarity will generate a repulsive force when they approach each other to avoid contact. The vertical length of magnetic plate a9 is greater than the vertical length of magnetic plate b10 to increase the speed of repulsion between the two. The vertical height of magnetic plate a9 can be adjusted as needed to meet the speed and distance of repulsion in different situations.
[0026] like Figure 1 As shown, a flange interface b7 is provided on the lower side of the flange interface a4, and a plurality of fixing holes 6 are equidistantly provided at the four corners of the lower end outer wall of the flange interface b7, and the interiors of the plurality of fixing holes 6 are all threadedly connected with connecting rods 5 which are fixedly connected upwardly and between the flange interface a4, and a plurality of vertical poles 3 are equidistantly provided on the upper end outer wall of the flange interface a4.
[0027] The flange interface a4 and the flange interface b7 are connected as a whole by the connecting rod 5 to be clamped and fixed on the quartz tube body 8. When the quartz tube body 8 moves, it can be moved and positioned between the vertical rod 3 and the corresponding plug-in positioning parts inside the auxiliary chamber body 1.
[0028] like Figure 1 As shown, a plurality of uprights 3 extend from the interior of the connecting rod 5 , and the transverse length of the flange interface a4 is smaller than the transverse length of the through opening 2 .
[0029] This ensures that the flange interface a4 can be stably and accurately inserted into the through-port 2 to work when it needs to be plugged into the through-port 2.
[0030] The implementation principle of this embodiment is: when the feeding quartz tube body 8 moves upward into the auxiliary chamber body 1, the magnetic plate a9 of the feeding quartz tube body 8 and the magnetic plate b10 on the inner wall of the lower edge opening 2 of the auxiliary chamber body 1 repel each other with the same polarity, and the quartz feeder will maintain a certain distance from the lower edge of the auxiliary chamber body 1 without contact, so that no contact will occur and interference will be avoided.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
