Description

TECHNICAL FIELD

[0001] The utility model relates to a smoke purifier technical field, concretely is a moxibustion smoke purification unit electric field machine core. BACKGROUND

[0002] Moxibustion smoke contains a large amount of oil fume, and the oil fume generated by moxibustion treatment cannot be directly discharged into the air, and needs to be discharged after purification, and we purify the oil fume in the moxibustion smoke through the electrostatic oil fume purifier. The core component of the smoke purifier is the electric field machine core, which generates high-voltage static electricity when powered on. When the oil fume enters the electric field machine core, it will be ionized by the electric field. The oil fume is ionized and has a negative charge, which is adsorbed by the electric field machine core, achieving the purpose of removing the oil fume in the discharged smoke.

[0003] The existing electric field machine core is mostly made of stainless steel and has a frame structure. Frequent disassembly and cleaning can cause the needle holder to deform. At the same time, the cathode needle on the needle holder also has installation requirements. It cannot deviate from the anode cylinder axis by 3mm, otherwise the electric field machine core will not work. Because the existing electric field machine core cathode needle is connected to the needle holder at only one end, the contact area is small and the connection strength is low, which can cause the needle holder and cathode needle to be not firmly connected, resulting in deformation and damage, affecting normal use. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a moxibustion smoke purification unit electric field machine core, which solves the problem of the existing moxibustion smoke purification unit electric field machine core cathode needle and needle holder connection not firm, which can cause deformation and damage, affecting normal use.

[0005] To solve the above technical problems, the utility model provides the following technical scheme:

[0006] A moxibustion smoke purification unit electric field machine core, comprising an outer frame, a needle holder, an insulator, an anode cylinder and a cathode needle, the anode cylinder is transversely installed on the outer frame, and the two ends of the anode cylinder are bent and folded with the flanges located outside the outer frame, one end of the cathode needle is fixedly connected with the needle holder, the cathode needle is inserted into the anode cylinder and located on the axis of the anode cylinder, a sharp discharge needle is arranged on the cathode needle, and the outer frame and the needle holder are fixedly connected through the insulator and a bolt and nut.

[0007] The needle holder is a rectangular frame structure, the insulator has six and is located at the four corner positions of the needle holder and the midpoint position of the longer side of the needle holder, a limiting plate is installed on one side of the needle holder close to the outer frame, and limiting holes corresponding to the cathode needle are arranged on the limiting plate.

[0008] Preferably, the cathode needle is inserted into the needle holder, and an end cap is fixedly connected to the end of the cathode needle away from the anode cylinder. Both the cathode needle and the end cap are welded and fixed to the needle holder.

[0009] Preferably, the cathode needle has laser-cut perforations equidistantly arranged along the axial direction, and the tip discharge needle is inserted and fixed in the laser-cut perforations, with the tip discharge needles equidistantly arranged along the circumference of the cathode needle.

[0010] Preferably, a wedge-shaped pad is fixed between the limiting plate and the needle holder, and the wedge-shaped pad is located between two adjacent insulators on the longer side of the needle holder.

[0011] Preferably, both ends of the limiting hole have rounded corners, and the central inner diameter of the limiting hole is the same as the diameter of the cathode needle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Existing electric field cores typically only install insulators at the four corners of the needle holder. This invention, however, installs insulators at all four corners of the needle holder and at the midpoint of the longer side of the needle holder. By using six insulators to install the needle holder, the stability of the needle holder installation is improved, making it less prone to deformation, thereby improving the accuracy of the cathode needle position. The cathode needle is fixed by the limiting plate, needle holder, and end cap, increasing the connection strength of the cathode needle and making the determination of the cathode needle position more accurate. This improves the operational stability of the electric field core and solves the problem that the cathode needle and needle holder of existing moxibustion smoke purification unit electric field cores are not firmly connected, which can easily lead to deformation and damage, affecting normal use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: an electric field core for a moxibustion smoke purification unit, such as... Figures 1-7 As shown, it includes an outer frame 1, a needle holder 2, an insulator 3, an anode cylinder 4, and a cathode needle 5. The anode cylinder 4 is horizontally installed on the outer frame 1, and both ends of the anode cylinder 4 are bent and folded with flanges 41 located on the outside of the outer frame 1. One end of the cathode needle 5 is fixedly connected to the needle holder 2. The cathode needle 5 is inserted into the needle holder 2, and the end of the cathode needle 5 facing away from the anode cylinder 4 is fixedly connected to an end cap 8. Both the cathode needle 5 and the end cap 8 are welded and fixed to the needle holder 2.

[0026] like Figures 1-7 As shown, the needle frame 2 is a rectangular frame structure. There are six insulators 3 located at the four corners of the needle frame 2 and at the midpoint of the longer side of the needle frame 2. A limiting plate 7 is installed on the side of the needle frame 2 near the outer frame 1. The limiting plate 7 is provided with limiting holes 71 corresponding to the cathode needles 5. Both ends of the limiting holes 71 are rounded, and the inner diameter of the center of the limiting holes 71 is the same as the diameter of the cathode needles 5. A wedge-shaped pad 9 is fixed between the limiting plate 7 and the needle frame 2, and the wedge-shaped pad 9 is located between two adjacent insulators 3 on the longer side of the needle frame 2.

[0027] like Figures 1-7 As shown, the cathode needle 5 is inserted into the anode cylinder 4 and located on the axis of the anode cylinder 4. The cathode needle 5 is provided with a tip discharge needle 6. The cathode needle 5 is provided with laser-cut perforations 51 at equal intervals along the axial direction. The tip discharge needle 6 is inserted and fixed in the laser-cut perforations 51. The tip discharge needle 6 is provided at equal intervals along the circumference of the cathode needle 5. The outer frame 1 and the needle holder 2 are fixedly connected by insulators 3 and bolts and nuts.

[0028] Working principle:

[0029] like Figures 1-9 As shown, an end cap 8 is welded to one end of the cathode needle 5. The cathode needle 5 is inserted into the needle holder 2 and the limiting plate 7. Both the cathode needle 5 and the end cap 8 are welded and fixed to the needle holder 2, which improves the connection strength of the cathode needle 5 end. The limiting plate 7 is sleeved on the cathode needle 5 through the limiting hole 71. When the wedge-shaped pad 9 is inserted, it pushes the limiting plate 7 to move to the left, which has the function of correcting the angle of the cathode needle 5, reducing the angle error generated when the cathode needle 5 is welded to the needle holder 2, and ensuring that the cathode needle 5 is located in the center inside the anode cylinder 4. The cathode needle 5 is installed and fixed by the limiting plate 7, the needle holder 2 and the end cap 8, which makes the determination of the position of the cathode needle 5 more accurate. The needle holder 2 is installed by six insulators 3, which improves the stability of the installation of the needle holder 2, making the needle holder 2 less prone to deformation during installation, disassembly, cleaning and long-term use, laying the foundation for ensuring the accurate position of the cathode needle 5. In addition, the flanges 41 set at both ends of the anode cylinder 4 also improve the firmness of its connection with the outer frame 1.

[0030] The electric field core of this utility model, when used in conjunction with the primary filter 10 installed at the air inlet of the smoke collection pipe, will have a better purification effect. The primary filter 10 is made of 304 stainless steel with a 20-mesh filter screen. The opening is snapped into the air inlet of the pipe and connected to the hanger installed inside the pipe through the mounting screw hole 101 on the top, and fixed with a wing nut. It can not only intercept dust, but also facilitate disassembly and cleaning, and prevent dust from entering the electric field core through smoke and fumes, which would make the electric field core difficult to clean.
