[0002] The bag filter is also called an integrated filter. Due to its large filtration surface area, it is often used for filtering large-volume liquids. Most of the existing bag filters are composed of a housing and a core, and are connected to the external pipeline system through the liquid inlet interface and the liquid outlet interface provided on the housing.

[0003] The existing authorized patent CN219559264U discloses a bag filter, which connects and fixes the upper and lower protective housings by using fixing bolts, and at the same time ensures the stable sealing of the whole instrument through the gasket provided between the two housings.

[0004] However, in the above way, when connecting and fixing the two housings by opening threaded holes and bolts, although the normal disassembly and installation between the upper and lower housings can be ensured, tools are required to disassemble or tighten the bolts one by one during disassembly and installation. Moreover, since the normal connection of the two housings depends on the bolts, the bolts need to be collected and watched after disassembly. When the bolts accidentally fall, bolts of the same model and size need to be found for installation, making the disassembly and installation operations of the two housings relatively troublesome. Summary of the Utility Model

The lower cover 103 has a lock hole 114 and a clamping groove 115. Through the foregoing solution, when connecting and fixing two outer shells by opening threaded holes and bolts, although the normal disassembly and installation between the upper and lower outer shells can be ensured, tools are required to disassemble or tighten the bolts one by one during disassembly and installation. Moreover, since the normal connection of the two outer shells depends on the bolts, the bolts need to be collected and protected after disassembly. When the bolts accidentally fall off, bolts of the same model and size need to be found for installation, making the disassembly and installation operation processes between the two outer shells relatively troublesome.

[0025] In this embodiment, the air release pipe 102 is installed on one side of the upper cover 101, the filter element 104 is arranged between the upper cover 101 and the lower cover 103. The upper cover 101, the lower cover 103 and the filter element 104 are all basic components of an existing bladder filter. Corresponding upper and lower connectors are provided on both the upper cover 101 and the lower cover 103. At the same time, the upper cover 101 is also provided with the corresponding air release pipe 102 to facilitate the air release operation inside the entire filter.

[0026] Among them, the sleeve holder 105 is fixedly connected to the upper cover 101 and is located on the side of the upper cover 101 close to the lower cover 103. The sliding lock holder 106 is slidably connected to the sleeve holder 105 and is located on the side of the sleeve holder 105 close to the lower cover 103. Both sides of the compression spring 107 are connected to the sliding lock holder 106 and the sleeve holder 105 respectively. The sealing gasket 108 is installed between the upper cover 101 and the lower cover 103. The driving member is connected to the sleeve holder 105. The operating member is located on one side of the sleeve holder 105. The mating inclined groove 112 is located on the side of the sliding lock holder 106 close to the inclined platform 110. The locking frustum 113 is located on the side of the sliding lock holder 106 close to the lower cover 103. The lock hole 114 is located on one side of the lower cover 103. The card slot 115 is located on the side of the lower cover 103 close to the sealing gasket 108. The sleeve holder 105 is fixedly installed at the lower end of the upper cover 101. A part of the sleeve holder 105 is sleeved on the surface of the lower cover 103. The four groups of the sliding lock holders 106 and the compression spring 107 provided inside the sleeve holder 105 are all within the range of the area where the sleeve holder 105 is sleeved on the surface of the lower cover 103. The locking frustum 113 provided on the side of the sliding lock holder 106 matches the lock hole 114 provided on the lower cover 103. After the upper cover 101 and the lower cover 103 are completed in mating, the locking frustum 113 on the side of the sliding lock holder 106 can be mated with the lock holes 114 provided around the lower cover 103, so as to complete the fixed connection between the upper cover 101 and the lower cover 103. The card slot 115 provided on the lower cover 103 is used to place the sealing gasket 108. By providing the sealing gasket 108, the sealing performance of the interface after connection with the upper cover 101 can be ensured.

[0027] Secondly, the moving ring 109 is slidably connected to the sleeving frame 105 and is located inside the sleeving frame 105; the inclined platform 110 is fixedly connected to the moving ring 109 and is located on one side of the moving ring 109 close to the sliding lock frame 106; both sides of the jacking spring 111 are connected to the moving ring 109 and the sleeving frame 105 respectively. The moving ring 109 matches the chute provided inside the sleeving frame 105. The inclined platform 110 for cooperating with the mating inclined groove 112 of the sliding lock frame 106 is fixedly installed at the bottom of the moving ring 109. When the moving ring 109 slides downward under the action of the operating member, the inclined platform 110 provided at the bottom of the moving ring 109 can drive the sliding lock frame 106 to slide through cooperation with the sliding lock frame 106, so that the locking frustum 113 of the sliding lock disengages from the lock hole 114 of the lower cover 103, thereby completing the unlocking between the upper cover 101 and the lower cover 103.

[0028] When the capsule filter of this embodiment is in use, the four sliding lock frames 106 provided on the sleeve frame 105 and the corresponding compression springs 107 cooperate with the lock holes 114 provided on the lower cover 103, so as to lock the upper cover 101 and the lower cover 103. After the upper cover 101 and the lower cover 103 are matched, a sealing gasket 108 is provided on the card slot 115 of the lower cover 103. By installing the sealing gasket 108, the sealing inside can be ensured after the upper cover 101 and the lower cover 103 are connected. When the user needs to disassemble the upper cover 101 and the lower cover 103, the operation member can be used to drive the moving ring 109 to move downward, and then the downward movement of the moving ring 109 cooperates with the inclined platform 110 to drive the four sliding lock frames 106, so as to squeeze and compress the four sliding lock frames 106 back, so that the locking round platform 113 of the sliding lock frame 106 is withdrawn from the lock hole 114 of the lower cover 103, which is convenient for the user to directly disassemble the upper cover 101 and the lower cover 103. It should be noted that when the upper cover 101 and the lower cover 103 are installed subsequently, the user can first use the operation member to cooperate with the movement of the moving ring 109 and the inclined platform 110 to squeeze and retract the locking round platform 113 of the four sliding lock frames 106, and then splice the upper cover 101 and the lower cover 103 installed with the sealing gasket 108. After the upper cover 101 and the lower cover 103 are installed, rotate the lower cover 103 so that the sliding lock can cooperate with the lock hole 114 of the lower cover 103 under the action of the compression spring 107, thereby completing the locking connection between the upper cover 101 and the lower cover 103, realizing that the user can disassemble and install the upper and lower shells more conveniently and quickly through the provided components, so as to facilitate the user to replace the inner core inside the shell.
