Description

Technical Field

[0001] This utility model relates to the field of oil fume purification technology, and more specifically, to a water-blocking structure for a self-cleaning oil fume purifier. Background Technology

[0002] In buildings, kitchen exhaust fumes enter a common flue. The fumes in the common flue contain a large number of oily particles. In order to reduce environmental pollution, self-cleaning fume purifiers are used to purify the fumes. In order to improve the purification effect, cleaning agents are sprayed. In order to prevent the cleaning agents from flowing into the room through the flue, a water-blocking structure is used to block them.

[0003] A search revealed a prior art patent for a water-blocking structure and a similar self-cleaning fume purifier, with publication number CN222210472U. The specification describes a system where a water collection trough and a baffle plate positioned near it are used. A pushing mechanism controls the baffle plate to rotate, allowing it to open normally and not obstruct the flow of flue gas, thus improving exhaust and purification efficiency. When the fume purifier requires spray cleaning, the baffle plate rotates to block the flue inlet, allowing the spray liquid dripping from the vertical flue to flow along the baffle plate into the water collection trough and be discharged, preventing the spray liquid from entering the flue.

[0004] However, in actual use, the existing technology, with the baffles directly attached to each other, makes the contact surface relatively flat, which reduces the sealing effect and allows some water to still drip into the flue, thus affecting the service life of the flue. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-blocking structure for a self-cleaning fume purifier, so as to solve the problem that in the prior art, the water-blocking plates are directly attached to each other, making the bonding surface relatively flat, which reduces the sealing effect and causes some water to drip into the flue, thus affecting the service life of the flue.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a water-blocking structure for a self-cleaning fume purifier, including a smoke exhaust pipe, a placement plate fixedly connected to the inner wall of the smoke exhaust pipe, a drainage groove opened at the top of the placement plate, connecting grooves opened on both the left and right sides of the interior of the placement plate, a locking groove opened on both the front and rear sides of the inner wall of the connecting groove, a locking block locked inside the locking groove, two storage grooves opened on the inner wall of the smoke exhaust pipe, a baffle hinged inside the storage groove, a placement groove opened on the inner side of the baffle, a limiting block fixedly connected to both the front and rear sides of the inner wall of the placement groove, the limiting block fitting against the inner wall of the placement plate, a connecting block fixedly connected to the middle of the inner wall of the placement groove, and the locking block slidably connected inside the connecting block.

[0007] The connecting block has two mounting slots inside. A mounting piece is fixedly connected to the side of the block away from the slot. An elastic element is fixedly connected to the end of the mounting piece away from the block. The other end of the elastic element is fixedly connected to the inner wall of the mounting slot.

[0008] The placement plate has limit grooves on both the left and right sides, and protrusions are fixedly connected to the inner walls of the limit grooves. Limit blocks are fixedly connected to the inner walls of the placement grooves, and grooves are formed on the side of the limit blocks away from the placement grooves.

[0009] The diversion channel is an inclined channel structure, the baffle is slidably connected to the inner wall of the exhaust pipe, and the connecting block is slidably connected inside the connecting channel.

[0010] The side of the card block away from the mounting piece is an arc-shaped block structure. The card block is slidably connected inside the mounting groove, and the mounting piece is slidably connected inside the mounting groove.

[0011] The limiting block is slidably connected to the outside of the placement plate, and the limiting block fits into the inside of the limiting groove.

[0012] The limiting block slides against the protrusion, and the protrusion fits against the inner wall of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, by installing a seal at the connection between the baffle and the placement plate and using a locking block to limit it, the connection between the baffle and the placement plate is well sealed and has good connection stability. Water will not drip into the flue, thus extending the service life of the flue. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a water-blocking structure for a self-cleaning fume purifier, including a smoke exhaust pipe 1, a placement plate 3 fixedly connected to the inner wall of the smoke exhaust pipe 1, a diversion groove 4 opened at the top of the placement plate 3, the diversion groove 4 is a sloping groove structure, the diversion groove 4 is used to guide water to flow forward, thereby guiding the water to be discharged to the outside, connecting grooves 17 are opened on both the left and right sides of the interior of the placement plate 3, and locking grooves 6 are opened on both the front and rear sides of the inner wall of the connecting grooves 17, with locking blocks 7 locked inside the locking grooves 6, and two storage grooves 2 are opened on the inner wall of the smoke exhaust pipe 1, with baffles 5 hinged inside the storage grooves 2, the storage grooves 2 providing installation space for the baffles 5. The baffle 5 is slidably connected to the inner wall of the exhaust pipe 1, allowing the baffle 5 to slide smoothly. A placement groove 9 is provided on the inner side of the baffle 5. Limiting blocks 16 are fixedly connected to both the front and rear sides of the inner wall of the placement groove 9. The limiting blocks 16 fit against the inner wall of the placement plate 3, so that the limiting blocks 16 can seal the placement plate 3 and prevent water leakage. A connecting block 8 is fixedly connected to the middle of the inner wall of the placement groove 9. The connecting block 8 is slidably connected inside the connecting groove 17, which provides installation space for the connecting block 8. The locking block 7 is slidably connected inside the connecting block 8, so that the connecting block 8 can be limited, thereby allowing the placement plate 3 and the baffle 5 to be stably connected.

[0025] When water blocking is required, the baffle 5 is rotated to fit against the placement plate 3, thereby allowing the limiting block 16 to fit against the interior of the placement plate 3. This sealing action of the limiting block 16 seals the baffle 5 against the placement plate 3. The two locking blocks 7 are then moved to opposite sides, allowing them to engage with the inner wall of the slot 6. This ensures a stable connection between the placement plate 3 and the baffle 5, resulting in a good seal and preventing water from dripping into the flue, thus extending the service life of the flue.

[0026] Example 2: Based on Example 1, in order to facilitate the pushing of the locking block 7, two mounting slots 10 are opened inside the connecting block 8. The side of the locking block 7 away from the slot 6 is fixedly connected to the mounting piece 11. The side of the locking block 7 away from the mounting piece 11 is an arc block structure, which allows the locking block 7 to slide inside the slot 6. The locking block 7 is slidably connected inside the mounting slot 10. The mounting slot 10 provides moving space for the locking block 7. The mounting piece 11 is slidably connected inside the mounting slot 10. The mounting slot 10 plays a limiting role for the mounting piece 11, which allows the mounting piece 11 to slide smoothly. The end of the mounting piece 11 away from the locking block 7 is fixedly connected to the elastic element 12. The other end of the elastic element 12 is fixedly connected to the inner wall of the mounting slot 10.

[0027] When the connecting block 8 slides into the interior of the connecting groove 17, the arc of the locking block 7 slides against the inner wall of the connecting groove 17, thereby allowing the locking block 7 to move inward. This allows the locking block 7 to push the mounting piece 11 inward, which in turn causes the mounting piece 11 to compress the elastic element 12 and deform. When the connecting block 8 is in contact with the inner wall of the connecting groove 17, the elastic element 12 performs a reset movement, which in turn causes the elastic element 12 to push the mounting piece 11 outward, allowing the mounting piece 11 to push the locking block 7 to engage with the inner wall of the locking groove 6.

[0028] Example 3: Based on Example 2, in order to further improve the sealing performance, limiting grooves 13 are provided on both the left and right sides of the placement plate 3. A protrusion 14 is fixedly connected to the inner wall of the limiting groove 13, and a limiting block 16 is fixedly connected to the inner wall of the placement groove 9. The limiting block 16 is slidably connected to the outside of the placement plate 3, so that the limiting block 16 can be squeezed and deformed. The limiting block 16 fits into the inside of the limiting groove 13, so that the limiting block 16 can initially seal the connection between the placement plate 3 and the baffle 5. A groove 15 is provided on the side of the limiting block 16 away from the placement groove 9. The limiting block 16 slides with the protrusion 14, so that the limiting block 16 can be squeezed again. The protrusion 14 fits into the inner wall of the groove 15, so that the limiting block 16 can seal the connection between the placement plate 3 and the baffle 5 again.

[0029] When the placement plate 3 slides into the placement groove 9, the limiting block 16 can slide against the outside of the placement plate 3, so that the limiting block 16 can be squeezed and deformed. When the placement plate 3 and the placement groove 9 are in contact, the limiting block 16 can fill the inside of the limiting groove 13 and fit tightly against the protrusion 14, thereby making the connection between the placement plate 3 and the baffle 5 better sealed by the limiting block 16.

[0030] The working process of this utility model is as follows:

[0031] When water blocking is required, the baffle 5 is rotated to fit against the placement plate 3, allowing the placement plate 3 to slide into the placement groove 9 and the connecting block 8 to slide into the connecting groove 17. During this process, the limiting block 16 slides against the outside of the placement plate 3, causing it to be compressed and deformed. After the placement plate 3 fits against the placement groove 9, the limiting block 16 fills the interior of the limiting groove 13 and fits tightly against the protrusion 14, thus ensuring a good seal at the connection between the placement plate 3 and the baffle 5. Furthermore, the arc of the locking block 7... The connecting block 8 slides against the inner wall of the connecting groove 17, allowing the locking block 7 to move inward. This allows the locking block 7 to push the mounting piece 11 inward, causing the mounting piece 11 to compress the elastic element 12 and deform. When the connecting block 8 is in contact with the inner wall of the connecting groove 17, the elastic element 12 performs a reset movement, allowing the elastic element 12 to push the mounting piece 11 outward. This allows the mounting piece 11 to push the locking block 7 to engage with the inner wall of the groove 6, resulting in a better connection seal. This prevents water from dripping into the flue, thus extending the service life of the flue.
