Description

Technical Field

[0001] The invention relates to the technical field of pipe connection, in particular to a flue hose quick-release connector. Background Art

[0002] At present, there are several common installation methods for flue check valves used in kitchen decoration: one is to fix the flue check valve base by nailing, the other is to fix the flue check valve base by gluing, and the range hood and the check valve are connected by a hose.

[0003] Chinese patent CN207333369U discloses a fixing mechanism for a flue check valve. By setting a spring sheet, the pipe body has the advantages of fast limit installation without nailing and support. By setting a positioning groove, the spring sheet will not deviate during the extrusion process, ensuring a good positioning and installation effect of the pipe body.

[0004] The above-mentioned device installs the check valve on the flue through the spring sheet, but no relevant structure is set for the connection between the check valve and the hose. Therefore, one end of the hose can only be connected to the check valve by tape or a clamp. Since the space above the ceiling is relatively small, it is not convenient to quickly disassemble and install the hose later after installing it in the above manner. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a flue hose quick-release connector to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0033] like Figure 1-Figure 9 As shown, a flue hose quick-release connector comprises a flue 1 and a connecting pipe 2 arranged on the flue 1. In actual use, the connecting pipe 2 can be fixedly installed on the flue 1 by bolts, and a tubular connector 3 is arranged at one end of the connecting pipe 2 away from the flue 1. A hose 4 matching with a range hood is fixedly installed at one end of the connector 3 away from the flue 1. Figure 8-Figure 9 As shown, a check valve is installed in the connecting pipe 2. Specifically, the check valve includes a bracket 12 fixedly arranged inside the connecting pipe 2. The bracket 12 is disc-shaped, and two blades 5 are elastically installed on the side of the bracket 12 away from the joint 3. Two openings are symmetrically arranged on the bracket 12, and the blades 5 are arranged at the openings. When the range hood is working, the airflow will flow into the connecting pipe 2, thereby squeezing the blades 5 to deflect them, so that the airflow can be introduced into the flue 1.

[0034] Further, refer to Figure 7-Figure 9 As shown, a vertical groove 1203 is provided on one side of the bracket 12 close to the blade 5, and the groove 1203 is located at the center of the bracket 12. A sleeve 16 is fixedly arranged in the groove 1203, and a connecting shaft 7 is rotatably installed in the sleeve 16. A support rod 15 is fixedly arranged between the blade 5 and the connecting shaft 7. Through this structure, the blade 5 can rotate relative to the bracket 12.

[0035] Reference Figure 3-Figure 8As shown, a plug rod 8 is fixedly provided on the inner wall of the connector 3, and a through groove 1201 cooperating with the plug rod 8 is provided on the bracket 12. A clamping block 801 is elastically installed on one side of the bottom of the plug rod 8, and the bottom end of the clamping block 801 is set as an inclined surface 8011. When one end of the plug rod 8 passes through the through groove 1201 and cooperates with the bracket 12 through the clamping block 801, the connector 3 can be stably docked with the connecting pipe 2. When the plug rod 8 is locked with the bracket 12, the clamping block 801 is connected to the topmost connecting shaft 7 through a traction assembly. Specifically, when the hose 4 is damaged and causes air leakage, the angle of rotation of the connecting shaft 7 driven by the blade 5 will be reduced. At this time, the traction assembly can cause the clamping block 801 to shrink into the plug rod 8, so that the plug rod 8 is disconnected from the bracket 12, which is conducive to the separation of the connector 3 from the connecting pipe 2.

[0036] A slide bar 10 is fixedly arranged on one side of the bracket 12 close to the flue 1. The number of the slide bars 10 is set to two groups and distributed at the upper and lower ends of the groove 1203. A slide sleeve 902 is elastically installed on one end of the slide bar 10 away from the bracket 12. A baffle 9 is arranged above the slide sleeve 902, and the baffle 9 is fixedly connected to the slide sleeve 902. The top surface of the baffle 9 is parallel to the inner bottom surface of the through groove 1201.

[0037] Furthermore, a baffle bar 901 is elastically installed on the top of the baffle 9 and on the side away from the bracket 12, and the top of the baffle bar 901 is set as an inclined guide surface 9011. In actual use, when one end of the rod 8 passes through the through groove 1201, it will contact the inclined guide surface 9011 on the baffle bar 901. The baffle 9 can be driven to move in the direction away from the bracket 12 through the extrusion between the rod 8 and the guide surface 9011. When the sliding sleeve 902 moves to the extreme position, as the rod 8 continues to move, the baffle bar 901 will be squeezed into the baffle 9. At this time, the baffle 9 can move in the direction close to the bracket 12, and stop moving when the baffle 9 contacts the pop-up block 801.

[0038] Furthermore, a through guide hole 9021 is provided at the end of the sliding sleeve 902 away from the sliding rod 10. In actual use, the end of the sliding rod 10 extending into the sliding sleeve 902 can be sealed with the sliding sleeve 902. This structure can slow down the speed of the sliding sleeve 902 relative to the sliding rod 10.

[0039] The above-mentioned traction assembly includes a connecting block 802 arranged at the bottom of the insertion rod 8, the connecting block 802 is slidably matched with the insertion rod 8, and the connecting block 802 can move in the vertical direction relative to the insertion rod 8, refer to Figure 4As shown, the connecting block 802 is located on the side of the clamping block 801 away from the flue 1, and a notch 1202 is provided on the inner bottom surface of the through groove 1201. A traction block 11 matching with the connecting block 802 is elastically installed at the notch 1202. The traction block 11 can move in the vertical direction relative to the bracket 12. Figure 5 , Fig.11 As shown, the top of the traction block 11 is provided with a slot 1101, the cross section of the slot 1101 is set to be T-shaped, and the cross section of the connecting block 802 is also set to be T-shaped. Figure 4 As shown, when one end of the insertion rod 8 passes through the through slot 1201 and the clamping block 801 is in a pop-up state, the bottom end of the connecting block 802 can enter the slot 1101 on the traction block 11, and the traction block 11 can drive the connecting block 802 to move in the vertical direction. A pull rope 13 is fixedly arranged between the connecting block 802 and the clamping block 801, and the pull rope 13 passes through the insertion rod 8 and slidably cooperates with the insertion rod 8. The clamping block 801 can be driven to move in the vertical direction by the set pull rope 13;

[0040] Combination Figure 4 , Fig.10 As shown, arc-shaped magnetic plates 701 are fixedly embedded on the two connecting shafts 7 at the ends of the groove 1203, and the top surface of the magnetic plate 701 is flush with the end surface of the connecting shaft 7. The magnetic plate 701 is on the end surface of the connecting shaft 7 close to the end of the groove 1203. A magnetic block (the magnetic block is not shown in the figure) matching the magnetic plate 701 is fixedly embedded on the bottom end surface of the traction block 11. The magnetic plate 701 has different magnetic poles on the side opposite to the magnetic block. Specifically, in the non-working state, the blade 5 is closed. At this time, the magnetic plate 701 on the connecting shaft 7 can be in a staggered state with the magnetic block, and in the normal working state, the blade 5 can be deflected outward so that the magnetic plate 701 on the connecting shaft 7 is in a staggered state with the magnetic block. However, when the hose 4 is damaged due to long-term use, a part of the gas in the hose 4 will leak through the hose 4, thereby reducing the outward rotation angle of the blade 5. At this time, the magnetic plate 701 on the connecting shaft 7 can be aligned with the magnetic block.

[0041] Further, a notch is provided on the bottom surface of the insertion rod 8 to slide with the connection block 802. Figure 4 As shown, the insert rod 8 is provided with a guide channel 803 connected to the slot, one end of the guide channel 803 is connected to the slot, and the other end of the guide channel 803 extends to the bottom surface of the insert rod 8, and the above-mentioned connecting block 802 is sealed with the slot.

[0042] In actual use, the connector 3 is aligned with the connecting pipe 2 so that the insertion rod 8 on the connector 3 can pass through the through slot 1201 on the bracket 12. Since the bottom end of the block 801 is set as an inclined surface 8011, during the process of the insertion rod 8 passing through the through slot 1201, the inclined surface 8011 on the block 801 will contact the bottom surface of the through slot 1201, thereby squeezing the block 801 into the insertion rod 8. In addition, when one end of the insertion rod 8 passes through the through slot 1201 and contacts the baffle 901, the baffle 9 can be driven by the baffle 901 to move in a direction away from the bracket 12, so that a gap is left between the baffle 9 and the bracket 12, so that the block 801 can pop out and be inserted into the gap. During the movement, the baffle 9 can The sliding sleeve 902 can be driven to move relative to the sliding rod 10. When the sliding sleeve 902 moves to the limit position relative to the sliding rod 10, the sliding sleeve 902 and the baffle 9 stop moving. As the insertion rod 8 continues to move, the end of the insertion rod 8 will squeeze the baffle 901 so that the baffle 901 can be retracted into the baffle 9. When the block 801 is completely moved out of the through groove 1201, the block 801 can pop out and be located between the baffle 9 and the bracket 12, thereby locking the insertion rod 8 and the bracket 12, so that the joint 3 can be docked with the connecting pipe 2. As the baffle 901 is retracted into the baffle 9, the baffle 9 can follow the sliding sleeve 902 to reset. When the baffle 9 moves to a state of contact with the block 801, it stops moving.

[0043] According to the above description, when the range hood is not working, the blade 5 is in a closed state, and when the range hood is working, the blade 5 can be deflected outward. In these two states, the magnetic plate 701 and the magnetic block are in a staggered state, and the guide channel 803 is set to make the traction block 11 move slowly in the slot. Therefore, even if the magnetic plate 701 and the magnetic block can be aligned within a certain period of time during the normal deflection process of the blade 5, it is not enough to drive the connecting block 802 to move downward and pull the clamping block 801.

[0044] When the hose 4 is damaged due to long-term use or external factors, the airflow can leak through the hose 4. In this state, even if the range hood is in normal working condition, the generated airflow cannot push the blade 5 to move to the limit state, so that the magnetic plate 701 and the magnetic block can overlap in the vertical direction. At this time, the suction force between the magnetic plate 701 and the magnetic block can drive the traction block 11 to move downward, and the traction block 11 can drive the connecting block 802 to move downward. In this process, the connecting block 802 can pull the card block 801 through the pull rope 13 and cause the card block 801 to shrink to the insertion rod 8, when the block 801 is offset from the baffle 9 in the horizontal direction, the baffle 9 can be reset to the side of the bracket 12. Through this structure, when the range hood is turned off later, the blade 5 can drive the connecting shaft 7 to reset, so that the magnetic plate 701 and the magnetic block are offset again, but the baffle 9 is under the block 801 at this time, which helps to prevent the block 801 from popping out to the side of the bracket 12 again. At this point, the connector 3 and the connecting pipe 2 are in a non-locked state. Later, when the user replaces the structure, he only needs to pull the connector 3 in the direction away from the flue 1 to remove the connector 3, so that the overall disassembly and assembly is faster and more convenient.

[0045] To sum up, this device can quickly complete the docking of the connector 3 and the connecting pipe 2 by cooperating with the bracket 12 through the provided block 801, and when the hose 4 leaks and needs to be replaced, the block 801 can be in a state of being staggered with the bracket 12. In this state, the user only needs to push the connector 3 in a direction away from the flue 1 to remove it from the connecting pipe 2, and the overall operation is faster and more convenient.

[0046] like Figure 1-Figure 2 As shown, at least two positioning cylinders 201 are fixed on the outer wall of the connecting tube 2, and the positioning cylinder 201 is trumpet-shaped, and a positioning rod 301 that cooperates with the positioning cylinder 201 is fixed on the outer wall of the connector 3. Through this structure, it is helpful to locate the installation position of the connector 3. When one end of the positioning rod 301 is inserted into the interior of the positioning cylinder 201, the insertion rod 8 and the through groove 1201 can be in a colinear state.

[0047] As shown in FIG. 3 , a sealing ring 6 is embedded in the end surface of the joint 3 close to the connecting pipe 2 to improve the sealing between the joint 3 and the connecting pipe 2 .

[0048] Reference Figure 4As shown, the bottom of the insertion rod 8 is provided with a mounting groove that slides with the block 801, and a first spring is fixedly arranged between the inner end surface of the mounting groove and the block 801. The top surface of the baffle 9 is provided with a strip groove that slides with the baffle 901, and a second spring is fixedly arranged between the inner bottom surface of the strip groove and the baffle 901. The cross-sections of the inner cavities of the sliding rod 10 and the sliding sleeve 902 are both set to T-shaped. This structure can avoid separation between the sliding rod 10 and the sliding sleeve 902, and a limiting spring is fixedly arranged between the inner end surface of the sliding sleeve 902 and the sliding rod 10.

[0049] The bottom surface of the notch 1202 is provided with a through groove that slides with the traction block 11, and a support plate is fixedly arranged inside the through groove and near the bottom end. The support plate is in the shape of a "U" character, and a support spring is fixedly arranged between the support plate and the traction block 11. The notch 1202 can be connected to the groove 1203 through the provided through groove, and the top end face of the connecting shaft 7 at the top end is in contact with the top wall of the groove 1203.

[0050] Reference Fig. 9 As shown, at least two groups of support rods 15 and connecting shafts 7 are connected to a single blade 5, and the connecting shafts 7 at the top and bottom are located near the traction block 11, and the connecting shafts 7 can be rotatably matched with the sleeves 16 through bearings.

[0051] Reference Fig.12 As shown, an annular groove can be opened on the inner wall of the sleeve 16, and a coil spring 14 is provided at the annular groove. The two ends of the coil spring 14 are respectively fixedly connected to the inner wall of the annular groove and the outer wall of the connecting shaft 7, so as to achieve elastic cooperation between the blade 5 and the bracket 12. Of course, it can also be achieved by a torsion spring in actual use. Since it is a mature technical means in the anti-return valve, it will not be elaborated here.
