[0024] In order to explain the technical content and structural features of the utility model in detail, the following further description is made in combination with the embodiments and the accompanying drawings.
[0025] As Figures 1 to 8 shown, the utility model provides a kind of oil mist nozzle 10, for spraying out oil mist, the oil mist particle that sprays out is small, and the oil mist generated is used to lubricate and heat dissipation for tool, bearing, transmission pair etc.
[0026] The utility model discloses oil mist nozzle 10 is equipped with structure chamber 11, the lower end of structure chamber 11 opens in the bottom of oil mist nozzle 10 and forms oil mist outlet 111.Oil mist nozzle 10 is equipped with flow guide body 12 in structure chamber 11, flow guide body 12 extends downward from the top of structure chamber 11, and the lower end of flow guide body 12 is at a distance from oil mist outlet 111, and flow guide body 12 is equipped with for first passageway 121, and the wall surface of flow guide body 12 and structure chamber 11 form second passageway 13.First passageway 121, second passageway 13 are used to input oil gas flow respectively, or first passageway 121 is used to input oil gas flow and second passageway 13 is used to input the mixed fluid of oil gas flow and compressed air respectively.
[0027] First, it needs to point out that "oil gas flow" refers to the fluid formed after a certain amount of lubricating oil is mixed with compressed air, which has not been atomized, and can form oil mist after being atomized by oil mist nozzle.
[0028] Traditional oil mist nozzle is equipped with two flow channels, one of which is used to input compressed air, and the other is used to input a certain amount of lubricating oil droplets. Lubricating oil droplets and compressed air are not mixed in advance, and flow separately. After mixing at the end of the respective flow channels, oil mist is formed and sprayed out.
[0029] The utility model discloses a first amount of lubricating oil is mixed with compressed air and forms oil gas stream, and oil gas stream is input to oil mist nozzle 10, and a part of oil gas stream flows along first channel 121, and a part of oil gas stream flows along second channel 13, and the oil gas stream that flows from first channel 121 and the oil gas stream that flows from second channel 13 are finally mixed with each other at oil mist outlet 111, and oil mist is formed and is sprayed, and the content of liquid drop is reduced, thereby reducing the part that is not atomized, to generate more oil mist, and the atomization effect is improved.
[0030] It is worth pointing out that the oil mist nozzle 10 of the utility model can not adopt the compressed air access scheme, but compressed air is not input in first channel 121 or second channel 13 alone, and the utility model can input the mixed fluid of oil gas stream and compressed air in second channel 13, and the oil gas stream can be driven to flow more quickly due to the participation of compressed air, which helps to improve the output speed and output pressure of oil mist, and is suitable for different production occasions.
[0031] As shown in Figure 6 and Figure 7 , the width of second channel 13 continuously decreases from top to bottom, and second channel 13 forms a structure similar to a Venturi tube, and the oil gas stream (or the mixed fluid of oil gas stream and compressed air) output from second channel 13 has high flow rate and low pressure, which can attract the oil gas stream output from first channel 121, and the two collide and mix with each other, and finally form oil mist at oil mist outlet 111 and spray out.
[0032] As shown in Figure 7 and Figure 8 , structure chamber 11 includes first chamber 112, second chamber 113 and third chamber 114 connected in sequence from top to bottom. Second chamber 113 is a conical chamber, and the caliber of second chamber 113 continuously decreases from top to bottom. First chamber 112 and third chamber 114 are cylindrical chambers, and the caliber of first chamber 112 is larger than that of third chamber 114. The lower end of flow guide 12 extends into third chamber 114, and third chamber 114 is connected with oil mist outlet 111, which is a conical structure with an opening that continuously increases from top to bottom. The calibers of first chamber 112, second chamber 113 and third chamber 114 decrease in sequence, which helps to form a "Venturi tube" structure in second channel 13.
[0033] It is worth pointing out that the oil mist output from the first channel 121 and the second channel 13, part of the oil mist is mixed in the third chamber 114, part of the oil mist is mixed in the oil mist outlet 111, but most of the oil mist is mixed in the oil mist outlet 111, so the above description is described as the oil gas flow is mixed in the oil mist outlet 111, but the description does not constitute a limitation on the patent.
[0034] As shown in Figure 4 , Figure 7 and Figure 8 Further, the flow guide 12 extends into the third chamber 114 with a width smaller than the rest of the flow guide 12. Specifically, the flow guide 12 includes an upper flow guide structure 122 and a lower flow guide structure 123, the upper flow guide structure 122 is arranged in the first chamber 112 and the second chamber 113, and the lower flow guide structure 123 is arranged in the third chamber 114, the upper flow guide structure 122 is a tapered structure with a diameter decreasing from top to bottom, and the lower flow guide structure 123 is a cylindrical structure. The shape and structure of the flow guide 12 cooperate with the shape of the chamber 11, which helps to form a "Venturi" type structure in the second channel 13. It should be noted that the second channel 13 is annular, and the oil gas flow (or the mixed flow of oil gas and compressed air) flows from top to bottom in the annular second channel 13.
[0035] As shown in Figure 1 , Figure 6 , Figure 7 and Figure 8 To facilitate the introduction of the oil gas flow into the first channel 121, the top of the oil mist nozzle 10 is provided with a flow guide chamber 14, and the upper end of the first channel 121 extends to and communicates with the flow guide chamber 14. Specifically, the flow guide chamber 14 is a tapered structure with a diameter decreasing from top to bottom, so as to quickly, effectively and reliably guide the oil gas flow into the first channel 121. The first channel 121 is a cylindrical structure with equal diameters in each part, and the first channel 121 is arranged vertically. Further, the first channel 121 is arranged concentrically with the oil mist nozzle 10.
[0036] It is worth noting that after the oil gas flow is injected into the flow guide chamber 14, part of the oil gas flow directly flows into the first channel 121, and part of the oil gas flow flows into the second channel 13 after impacting the wall of the flow guide chamber 14, the gas in the oil gas flow turns upward, and then flows into the second channel 13, which makes the oil content of the oil gas flow flowing into the second channel 13 relatively small, and the oil content of the oil gas flow flowing into the first channel 121 relatively large, and the oil gas flow from the second channel 13 and the oil gas flow from the first channel 121 are mixed, which helps to further improve the atomization effect. The above-mentioned effect is achieved by setting the flow guide chamber 14 as a tapered structure and cooperating with the second channel 13.
[0037] AsFigures 1 to 5 , Figure 7 and Figure 8 As shown, the oil mist nozzle 10 also has multiple guide channels 15. One end of each guide channel 15 is connected to the upper end of the second channel 13, and the other end of each guide channel 15 opens into the side wall of the oil mist nozzle 10. Having multiple guide channels 15 helps to introduce multiple oil flow streams (or oil flow streams and compressed air) into the second channel 13. Preferably, the guide channel 15 has a cylindrical structure, and the central axis of the guide channel 15 is orthogonal to the central axis of the first channel 121. The oil mist nozzle 10 has a total of four guide channels 15, spaced 90° apart. However, depending on actual needs, more or fewer than four guide channels 15 can be provided.
[0038] like Figures 1 to 8 As shown, the oil mist nozzle 10 includes a first column 16 and a second column 17 that are detachably assembled. The bottom of the first column 16 protrudes downward to form a guide fluid 12. A guide chamber 14 and a first channel 121 are disposed within the first column 16 and the guide fluid 12. A structural chamber 11 is disposed within the second column 17. The guide fluid 12 also includes a connecting structure 124 disposed between the first column 16 and the upper guide structure 122. A drainage plane 161 extending from the top to the bottom of the first column 16 is cut out on the outer side wall of the first column 16, and the drainage plane 161 is vertically arranged. A drainage groove 162 is provided at the top of the first column 16, one end of which is connected to the guide chamber 14, and the other end of which opens into the drainage plane 161.
[0039] The second column 17 includes a first part 171 and a second part 172, with the second part 172 located below the first part 171. The first column 16 has the same radius as the first part 171, but the radius of the first part 171 is smaller than the radius of the second part 172. A flow guide 12 passes through the structural chamber 11, and the first column 16 is connected to the first part 171. The radius of the connecting structure 124 is slightly larger than or equal to the radius of the first chamber 112, allowing the connecting structure 124 to be fitted into the first chamber 112 with an interference fit or a transition fit. A flow channel 15 is located within the first part 171.
[0040] The oil mist nozzle 10 is mounted on a device (e.g., a spray gun). Figure 7 After being indicated by a dashed box, the oil and gas flow input into the guide chamber 14 splits into two streams, one of which flows into the first channel 121 (i.e., Figure 7 One stream flows in the direction of arrow K), while another flows out from the drainage channel 162 and down along the drainage plane 161 to the side wall of the first part 171, then flows into the guide channel 15, and finally flows into the second channel 13 (i.e. Figure 7The oil and gas flow is divided into two flows by the flow guide plane 161 and the flow guide groove 162, and the two flows flow into the first channel 121 and the second channel 13 respectively. By the way of combining the oil and gas flow first and then dividing the combined flow, the structure and arrangement are simplified.
[0041] Please refer to Figure 7 The compressed air is injected into the outer side of the first part 170, and then flows into the second channel 13 through the flow guide channel 15. The oil and gas flow from the flow guide groove 162 also flows into the flow guide channel 15 and then flows into the second channel 13. The two flows mix with each other to form the mixed flow in the second channel 13. It is worth mentioning that the compressed air does not flow into the flow guide chamber 14 because the flow guide chamber 14 is injected with the oil and gas flow, and the pressure is high. The pressure of the second channel 13 and the structure chamber 11 is relatively low. According to the entropy increase and entropy decrease effect, the compressed air only flows into the flow guide channel 15.
[0042] The oil mist nozzle 10 is divided into the first column 16 and the second column 17, which facilitates production and assembly.
[0043] In order to prevent the oil mist nozzle 10 from leaking after being installed in a device, the outer side of the lower end of the first part 171 is formed with a mounting groove 1711 for mounting a sealing ring (not shown in the figure). After the sealing ring is mounted in the mounting groove 1711, the oil and gas flow (or the mixed flow of the oil and gas flow and the compressed air) cannot continue to flow downward, but only flows into the second channel 13 through the flow guide channel 15.
[0044] Figure 2 In the figure, the direction indicated by the arrow Z is the upward direction.
[0045] The above only discloses preferred examples of the utility model, and cannot limit the scope of the utility model. Equivalent changes made according to the utility model claims all belong to the scope covered by the utility model.
