[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a vapor-liquid full-flow screw power machine with an improved air inlet structure, including a housing 1. One side of the top wall of the housing 1 is communicated with an air inlet pipe 3. The top end of the air inlet pipe 3 is provided with a connecting pipe 2. The outer periphery of the top end of the air inlet pipe 3 is fixedly connected with a first flange 4. The outer periphery of the bottom end of the connecting pipe 2 is fixedly connected with a second flange 5. Connecting strips 7 are arranged on both sides of the first flange 4 and the second flange 5. The top ends of the two connecting strips 7 are rotatably connected with a bidirectional screw 8. The bottom ends of the two bidirectional screws 8 penetrate through the inner wall of the connecting strip 7 and are rotatably connected to the inner bottom wall of the connecting strip 7. The outer peripheries of the upper and lower parts of the two bidirectional screws 8 are threadedly connected with arc plates 6. The adjacent sides of the upper and lower arc plates 6 are fixedly connected with uniformly distributed insertion rods 15. The bottom ends of the upper insertion rods 15 penetrate into the second flange 5, and the top ends of the lower insertion rods 15 penetrate into the first flange 4. On the far sides of the two bidirectional screws 8, limiting rods 13 are arranged. The top ends of the two limiting rods 13 are fixedly connected to the inner top wall of the connecting strip 7. The bottom ends of the two limiting rods 13 penetrate through the arc plates 6 and are fixedly connected to the inner bottom wall of the connecting strip 7.

[0032] Specifically, when it is necessary to install the connecting pipe 2 and the air inlet pipe 3, the connecting pipe 2 and the air inlet pipe 3 can be abutted. After the connecting pipe 2 and the air inlet pipe 3 are abutted, the correspondingly fixed first flange 4 will also be abutted against the second flange 5. Subsequently, the staff can place the connecting strip 7 on both sides of the first flange 4 and the second flange 5, and make the upper arc plate 6 be on the upper side of the second flange 5 and the lower arc plate 6 be on the lower side of the first flange 4. Then the staff can rotate the bidirectional screw 8 to drive the arc plates 6 connected above and below to move. Since the arc plate 6 is also limited by the limiting rod 13, the limiting rod 13 will limit the arc plate 6, so that the arc plate 6 will not rotate with the rotation of the bidirectional screw 8. Thus, the upper and lower arc plates 6 will approach or move away from each other along the bidirectional screw 8 at the same time. When the upper and lower arc plates 6 approach each other at the same time, they will drive the correspondingly connected insertion rods 15 to move, and make the upper insertion rods 15 insert into the second flange 5, and the lower insertion rods 15 insert into the first flange 4. Moreover, the two arc plates 6 will also clamp the first flange 4 and the second flange 5, so as to fix the connecting pipe 2 and the air inlet pipe 3. When it is necessary to disassemble the connecting pipe 2 and the air inlet pipe 3, only the bidirectional screw 8 needs to be rotated in the reverse direction to withdraw the insertion rods 15 from the first flange 4 and the second flange 5 respectively, and then the connecting pipe 2 and the air inlet pipe 3 can be disassembled. Thus, it is not necessary to screw multiple bolts to assemble and disassemble between the first flange 4 and the second flange 5, and further achieve the effect of facilitating the assembly and disassembly and fixing between the air inlet pipe 3 and the connecting pipe 2.

[0033] Refer to Figures 1 - 3, a dust cover 9 is provided at one end of the outer shell 1. Fixed strips 10 are fixedly connected to the front and rear sides of the outer periphery of the dust cover 9. Mounting blocks 11 are fixedly connected to the front and rear sides of the outer periphery of one end of the outer shell 1. One end of each of the two fixed strips 10 penetrates into the mounting block 11. Chambers 20 are opened inside the two mounting blocks 11. One end of a spring 19 is fixedly connected to both sides of the side walls away from each other inside the two chambers 20. The other end of the front and rear springs 19 is fixedly connected to a clamping block 18. The closer ends of the two clamping blocks 18 penetrate into the fixed strip 10. A pull rod 12 is fixedly connected to the farther side of each of the two clamping blocks 18. One end of each of the two pull rods 12 away from the clamping block 18 penetrates the outer wall of the mounting block 11; guide rods 21 penetrate through both ends of the two clamping blocks 18. The front and rear ends of the plurality of guide rods 21 are fixedly connected to the front and rear walls inside the chamber 20. The plurality of springs 19 are all arranged on the outer periphery of the guide rods 21;

[0034] Specifically, the dust cover 9 can provide dust protection for the output end when not in use. When it needs to be disassembled, pulling the pull rod 12 can drive the clamping block 18 to move. When the clamping block 18 is pulled out of the fixed strip 10 and retracted into the chamber 20, the limit of the clamping block 18 on the fixed strip 10 can be cancelled, so that the fixed strip 10 can be pulled out of the mounting block 11, facilitating the removal of the dust cover 9 from the outer shell 1. When the dust cover 9 needs to be installed, only the fixed strip 10 needs to be inserted into the mounting block 11. Since the fixed strip 10 will contact the clamping block 18 when inserted into the mounting block 11, and since the contact surface between the clamping block 18 and the fixed strip 10 is an inclined surface, as the fixed strip 10 is inserted, it will squeeze the clamping block 18 and push the clamping block 18 to move into the chamber 20. Since the spring 19 will also be compressed when the clamping block 18 moves, after the fixed strip 10 is completely inserted into the mounting block 11, under the action of the spring 19, the clamping block 18 can be inserted into the fixed strip 10 for fixation, and under the action of the guide rod 21, the spring 19 can be limited to prevent the spring 19 from bending when compressed, so as to fix the dust cover 9, and further achieve the effect of being able to provide dust protection for the device output port and facilitating the installation, disassembly and replacement of the dust cover 9.

[0035] Refer to Figures 1 - 3 , limiting grooves 16 are opened on both sides of the first flange 4 and the second flange 5. Limiting strips 17 are engaged in the limiting grooves 16 on both sides. The farther ends of the two limiting strips 17 are fixedly connected to the connecting strip 7; positioning strips 14 are fixedly connected to both sides of the bottom wall of the first flange 4. The bottom ends of the two positioning strips 14 penetrate into the second flange 5;

[0036] Specifically, by providing the limited position groove 16 and the limited position strip 17, when the connecting strip 7 is placed on both sides of the first flange 4 and the second flange 5, the limited position strip 17 can be inserted into the limited position groove 16, so as to position the connecting strip 7 during installation, achieving the effect of facilitating the installation of the connecting strip 7; by providing the positioning strip 14, positioning can be carried out after the first flange 4 and the second flange 5 are fitted, so as to ensure the coincidence of the limited position grooves 16, and further achieve the effect of facilitating the abutment of the first flange 4 and the second flange 5 at the accurate position.

[0037] Working principle: During actual use, after the connecting pipe 2 is abutted against the intake pipe 3, the first flange 4 will also be abutted against the second flange 5. Subsequently, the connecting strip 7 can be placed on one side of the first flange 4 and the second flange 5, and the upper arc plate 6 is located above the second flange 5, and the lower arc plate 6 is located below the first flange 4. Then, rotating the bidirectional screw rod 8 can drive the upper and lower arc plates 6 to approach simultaneously. When the arc plates 6 approach simultaneously, the insertion rods 15 can be driven to insert into the first flange 4 and the second flange 5 respectively and clamp them, thus achieving the effect of facilitating the installation and disassembly and fixation between the intake pipe 3 and the connecting pipe 2; in addition, through the dust-proof cover 9, the output end can be protected from dust when not in use. When it needs to be disassembled, pulling the pull rod 12 can drive the clamping block 18 to be pulled out from the fixing strip 10, so that the dust-proof cover 9 can be removed from the housing 1. When installation is required, only the fixing strip 10 needs to be inserted into the installation block 11. As the fixing strip 10 is inserted, it will push the clamping block 18 to move and compress the spring 19. Under the action of the spring 19, the clamping block 18 can be inserted into the fixing strip 10 for fixation, so as to fix the dust-proof cover 9, and further achieve the effect of being able to protect the output port of the device from dust and facilitating the installation, disassembly and replacement of the dust-proof cover 9.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
