[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0026] Please refer to the attached Figure 1-Figure 6 As shown, the utility model provides a technical solution: a pulse filter cartridge dust collector with a large contact area, including a shell 10, a filter chamber 101 and an exhaust chamber 102 are arranged in the shell 10, an air inlet pipe 11 is fixedly installed at the upper end of the filter chamber 101 of the shell 10, and an air outlet pipe 12 is fixedly connected to the lower end of the exhaust chamber 102 of the shell 10, and a collection box 15 is slidably installed at the bottom of the filter chamber 101 to facilitate the collection of dust in the shell 10, and four filter chambers are arranged in the filter chamber 101. The filter chamber 101 of the cylinder 20 is fixedly connected with a connection box 103 on the inner wall of the lower end of the air inlet pipe 11, and a plurality of air guide holes 104 are evenly opened on the outer surface of the connection box 103. A hollow tube 13 is fixedly installed in the middle position of the connection box 103, and the lower end of the hollow tube 13 passes through the lower surface of the connection box 103. A plurality of blocks 14 are evenly fixedly connected to the outer surface of the hollow tube 13, and the other ends of the plurality of blocks 14 are fixedly installed on the connection box 103 at a position between the plurality of air guide holes 104.

[0027] Specifically, the dust-containing gas is introduced into the shell body 10 from the air inlet pipe 11. Under the obstruction of the hollow tube 13 and a plurality of blocks 14, the dust-containing gas in the air inlet pipe 11 is divided into multiple parts. One part passes through the hollow tube 13 and falls onto the filter cartridge 20 below the hollow tube 13, and the remaining part passes through the gaps between the plurality of blocks 14 and the plurality of air guide holes 104 and is dispersed into various parts of the shell body 10. Then, the dust-containing gas falls onto various parts of the filter cartridge 20, thereby increasing the contact area between the dust-containing gas and the filter cartridge 20.

[0028] In this embodiment, both ends of the filter cartridge 20 pass through the surface of the shell 10 and the exhaust chamber 102 respectively. The side of the filter cartridge 20 close to the exhaust chamber 102 is open. An expansion port 16 is fixedly connected to the inner wall of the end of the exhaust chamber 102 close to the opening of the filter cartridge 20. A handle 201 is fixedly connected to the side of the filter cartridge 20 away from the exhaust chamber 102 to facilitate taking the filter cartridge 20.

[0029] In this embodiment, a fixing rod 22 is fixedly connected to one side of the shell 10, and a round block 221 is fixedly connected to the end of the fixing rod 22 away from the shell 10. A clamping block 21 is slidably installed on the fixing rod 22, and the fixing rod 22 passes through the outer surface of one end of the clamping block 21. A clamping groove 202 is provided on the side of the filter cartridge 20 close to the handle 201, and the end of the clamping block 21 away from the fixing rod 22 slides and engages in the clamping groove 202, so as to facilitate the fixing of the filter cartridge 20.

[0030] In this embodiment, a baffle 24 is rotatably installed at one end of the fixed rod 22 close to the round block 221, and the fixed rod 22 is arranged to pass through the outer surface of the baffle 24. A spring 23 is fixedly installed between the side where the baffle 24 and the clamping block 21 are close to each other, and the spring 23 is slidably sleeved on the outer surface of the fixed rod 22.

[0031] Among them, when the filter cartridge 20 is damaged and needs to be replaced, the block 21 is manually pulled to slide on the fixing rod 22 to squeeze the spring 23, so that the block 21 is completely out of the slot 202 at one end of the slot 202, and then the block 21 is rotated to further make the spring 23 drive the baffle 24 to rotate on the fixing rod 22, and the block 21 moves to other directions at one end of the slot 202, thereby releasing the lock on the filter cartridge 20, and the handle 201 is pulled to remove the filter cartridge 20 from the housing 10, and then after replacing the new filter cartridge 20, the reverse operation can be performed to fix the new filter cartridge 20.

[0032] In this embodiment, a pulse controller 25 is fixedly connected to one side of the shell 10 close to the exhaust chamber 102, and four conduction tubes 26 are fixedly connected to one side of the pulse controller 25 close to the shell 10. The four conduction tubes 26 respectively penetrate the outer surface of the shell 10 and extend into the exhaust chamber 102. The horizontal height of the four conduction tubes 26 is set to be the same as the horizontal height of the four filter cartridges 20.

[0033] In this embodiment, a wind speed sensor 27 is fixedly mounted on the surface of one end of the conductive tube 26 away from the pulse controller 25 .

[0034] Specifically, when the wind speed sensor 27 senses that the speed of the outgoing air has dropped significantly, the pulse controller 25 will compress the air and eject it through the four conduction tubes 26 at high speed. This high-speed airflow rushes into the four filter cartridges 20 in a very short time, causing the four filter cartridges 20 to expand and vibrate rapidly. The strong impact and vibration cause the dust layer attached to the surface of the four filter cartridges 20 to be peeled off and fall off, thereby achieving efficient cleaning.

[0035] In this embodiment, a rotating rod 31 is rotatably installed on the filter chamber 101 at the upper end of the collecting box 15, and a water pipe 30 is fixedly installed on the outer surface of the rotating rod 31. A plurality of spray heads 301 are evenly fixedly installed on one end of the water pipe 30 away from the rotating rod 31. One end of the rotating rod 31 passes through the outer surface of the shell 10 and is fixedly connected to a knob 32. A pointer 321 is fixedly installed on the outer surface of one side of the knob 32. The arrow indicating direction of the pointer 321 is set to be consistent with the spraying direction of the spray head 301, so as to facilitate the adjustment of the spraying direction of the spray head 301 as needed.

[0036] In this embodiment, the shell 10 is fixedly connected to a water tank 34 on one side of the filter chamber 101, and the upper end of the water tank 34 is fixedly connected to a water inlet 341. One end of the water pipe 30 passes through the outer surface of the shell 10 and is fixedly connected to the lower end of the water tank 34. One side of the bottom end of the shell 10 is fixedly connected to a bottom plate 105, and a water pump 33 is fixedly installed on the bottom plate 105. The water pump 33 is installed on the water pipe 30 between the water tank 34 and the shell 10.

[0037] Specifically, before opening the collection box 15, turn on the water pump 33, so that the water in the water tank 34 passes through the water pipe 30 and is then sprayed out from a plurality of spray heads 301 to reduce the dust on the upper end of the collection box 15 to prevent dust from being generated during collection and endangering human health.

[0038] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
