Description

Technical Field

[0001] The utility model relates to the technical field of static elimination equipment, in particular to an ion nozzle and an ion air bar. Background Art

[0002] Static electricity is generated by the accumulation of charges of the same polarity on an object, resulting in uneven charge distribution on the object surface. It is a very common natural phenomenon, mostly occurring in dry climates and environments.

[0003] However, in some industrial productions, due to the need for friction, extrusion, collision, etc. during product manufacturing, static electricity will be generated. Static electricity can break down electronic components. If this static electricity accumulates to a certain extent, an explosion will occur, and in severe cases, it will even pose a threat to property safety and human safety. Therefore, in the production site, static elimination equipment needs to be set up to release charges with the opposite polarity to the static charges in time to neutralize the static electricity and achieve the elimination effect.

[0004] In the current ion bar, the ion needle and the air hole are usually set together. The high-speed gas ejected at high speed can clean the ion needle, making the ion needle always clean and tidy. However, the static elimination effect of this ion bar is often affected by the airflow of the high-pressure gas. Unstable airflow will generate ion fluctuations and uneven ion mixing, resulting in a relatively high residual voltage of the product and poor static elimination effect. Summary of the Utility Model

[0005] Based on this, the utility model provides an ion nozzle. The gas through holes are separately arranged around the needle hole, so that the high-pressure gas ejected from each gas through hole can be evenly mixed with the positive and negative ion groups ejected from the needle hole, ensuring the balance of ions, reducing the ion fluctuations generated by the high-pressure gas airflow, and making the static elimination and cleaning effect more stable and better, and the residual voltage of the product lower.

[0027] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

[0030] As Figures 1 - 3 shown, an ion nozzle of this embodiment includes a mounting portion 1 and an annular jetting portion 2 extending from one end of the mounting portion 1. The annular jetting portion 2 is provided with a plurality of gas through holes 21. The plurality of gas through holes 21 penetrate through the mounting portion 1 and the annular jetting portion 2. A pinhole 22 is provided at the center of the annular jetting portion 2. The pinhole 22 penetrates through the mounting portion 1 and leads to the annular jetting portion 2. The plurality of gas through holes 21 are symmetrically arranged with respect to the pinhole 22. The traditional ion nozzle has poor ion balance, is easily affected by the air flow, generates ion fluctuations, resulting in a relatively high residual voltage of the product. During testing, the balance voltage often jumps from 5V to 50V, and the static elimination effect is unstable. However, in the ion nozzle of this embodiment, the gas through holes 21 are evenly distributed around the pinhole 22, and the gas through holes 21 are symmetrically arranged with respect to the pinhole 22, making the mixing of positive and negative ion groups and the high-pressure gas more uniform, keeping the residual voltage of the product below 20V, which is much lower than the requirement of 35V in ordinary electronics factories.

[0031] The ion nozzle of this utility model includes a mounting portion 1 and an annular jetting portion 2. A plurality of gas through holes 21 are provided in the circumferential direction of the annular jetting portion 2. A pinhole 22 is provided at the center of the annular jetting portion 2. The high-pressure gas is ejected from positions symmetrical with respect to the pinhole 22 and then mixed with the positive and negative ion groups ejected from the pin. Therefore, the mixing of positive and negative ion groups and the high-pressure gas is more uniform, and the ion balance after mixing is better. The ion nozzle with this structure is not easily affected by the air flow to generate ion fluctuations. Therefore, the static elimination and cleaning effect is better, and the residual voltage is lower and more stable.

[0032] As Figure 2 shown, a conical inclined surface is provided between the pinhole 22 and the annular jetting portion 2 of this embodiment. The conical inclined surface helps the positive and negative ion groups at the central position to be evenly mixed with the surrounding high-pressure gas, improving the mixing uniformity without affecting the flow rate of the high-pressure gas and ensuring the ion balance.

[0033] As Figures 1 - 3As shown in the figure, the first inlet end 211 of the gas through-hole 21 of this embodiment is located at one end of the mounting portion 1, the first outlet end 212 of the gas through-hole 21 is located at one end of the annular jet portion 2, the second inlet end 221 of the pinhole 22 is located at one end of the mounting portion 1, and the second outlet end 222 of the pinhole 22 is located at one end of the annular jet portion 2. The distance between the first inlet end 211 and the first outlet end 212 is H, the distance between the second inlet end 221 and the second outlet end 222 is h, H>h + a, and 0 < a < 50mm. The greater the difference between the distance H and the distance h, the farther the starting distance between the high-pressure gas and the positive and negative ion groups, and the more uniform the mixing degree. On the contrary, the smaller the difference between the distance H and the distance h, the closer the starting distance between the high-pressure gas and the positive and negative ion groups, the shorter the mixing time, and the more uneven the mixing degree. Specifically, the distance difference a between the two can be 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm.

[0034] As Figures 1 - 3 shown, the ion nozzle of this embodiment further includes a partition baffle 3, and the partition baffle 3 is arranged between the mounting portion 1 and the annular jet portion 2. When the ion nozzle is installed in the ion wind rod, the mounting portion 1 is threadedly connected to the housing 4, and the partition baffle 3 can be attached to the surface of the housing 4, so that the installation is more compact and air leakage is avoided; preferably, a sealing ring 201 is sleeved on the mounting portion 1, which can increase the sealing performance between the mounting portion 1 and the housing 4 and prevent high-pressure gas from leaking out from the gap between the two. Preferably, the vertical projection area of the partition baffle 3 is larger than the vertical projection area of the mounting portion 1, so as to increase the sealing performance between the ion nozzle and the housing 4.

[0035] As Figures 1 - 3 shown, the annular jet portion 2 of this embodiment is provided with a plurality of mounting protrusions 23 along the circumferential direction, and the plurality of mounting protrusions 23 are symmetrically arranged with respect to the pinhole 22. The mounting protrusions 23 provide assistance for the ion nozzle and facilitate the installation of the ion nozzle. Preferably, the mounting protrusions 23 are arranged from one side of the partition baffle 3 to the side away from the mounting portion 1, the mounting protrusions 23 protrude from the annular jet portion 2, and the thickness of the mounting protrusions 23 gradually increases from the inside to the outside. By designing the shape and structure of the mounting protrusions 23, it is more conducive to the ejection and mixing of high-pressure gas, avoiding excessive turbulence of the high-pressure gas, and enabling the high-pressure gas and the positive and negative ion groups to be mixed and sprayed onto the product in a certain flow direction, so as to achieve the effect of removing static electricity and cleaning the product.

[0036] As Figures 4 - 7As shown in the figure, an ion wind rod according to this embodiment includes a housing 4, a high-voltage generator 5, a circuit board 6, ionization needles 7, and an ion nozzle of any of the above. The housing 4 includes an installation cavity 41 and a gas channel 42. The high-voltage generator 5 is installed in the installation cavity 41, and the circuit board 6 is installed in the installation cavity 41. The circuit board 6, the high-voltage generator 5, and the ionization needles are electrically connected in sequence. The gas channel 42 is provided with an installation hole 421, and the installation part 1 of the ion nozzle is installed in the installation hole 421, and the ionization needles are inserted into the needle holes 22. Installing multiple ion nozzles of the above in the housing 4 to assemble an ion wind rod can effectively form a wind wall to remove static electricity and clean the objects passing by.

[0037] As Figures 5 - 7 shown, the ion wind rod of this embodiment further includes a positive metal guide piece 8 and a negative metal guide piece 9. The inner wall of the gas channel 42 is provided with a first card slot 422, and the positive metal guide piece 8 is clamped in the first card slot 422. The positive metal guide piece 8 is used to conduct the positive pole of the high-voltage generator 5 and the ionization needles 7. The outer wall of the gas channel 42 is provided with a second card slot 423, and the negative metal guide piece 9 is clamped in the second card slot 423. The positive metal guide piece 8 conducts the positive pole of the high-voltage generator 5 and the ionization needles 7, so as to form a high-voltage electric field with the negative metal guide piece 9 to ionize the air, forming a large number of positive and negative ion clusters, thereby removing static electricity from the product.

[0038] As Figures 4 - 6 shown, the ion wind rod of this embodiment further includes a network connection port 10. The network connection port 10 is electrically connected to the circuit board 6. The ion wind rod is also provided with a control panel and control buttons. The control panel can display the ventilation volume of the ion wind rod and the number of ion clusters generated by ionization, and the control buttons can adjust the size of the ventilation volume and the number of ion clusters, so as to control the static electricity removal and dust removal effects. The network connection port 10 can insert a network cable to remotely control the ion wind rod, and the practicability is good.

[0039] As Figures 4 - 7 shown, the ion wind rod of this embodiment further includes a high-pressure gas joint 20 and a sealing ring 201. The sealing ring 201 is arranged between the high-pressure gas joint 20 and the gas channel 42. The ion wind rod is connected to an external high-pressure gas source through the high-pressure gas joint 20 to provide high-pressure gas for the ion nozzle. The sealing ring 201 can improve the connection tightness, ensure that the gas maintains a certain air pressure state, and ensure the static electricity removal and cleaning effect.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
