Abstract
Claims
1. A filter assembly characterized by, include: The filter housing (1) includes a first cylindrical half-shell (11), a second cylindrical half-shell (12) and a detachable connection structure (3). The first cylindrical half-shell (11) and the second cylindrical half-shell (12) are joined at both ends in the circumferential direction and connected by the detachable connection structure (3) to form an axially through water passage cavity (13). The two ends of the water passage cavity (13) form an inlet (14) and an outlet (15) respectively. The filter element (2) is detachably installed in the water passage chamber (13) and between the water inlet (14) and the water outlet (15); The filter assembly is used to connect to the suction device of the water quality testing device to filter the water sample to be tested.
2. The filter assembly of claim 1, wherein, The first cylindrical half shell (11) is symmetrically provided with first mounting flanges (111) at both ends in the circumferential direction, and the second cylindrical half shell (12) is symmetrically provided with second mounting flanges (121) at both ends in the circumferential direction. The detachable connection structure (3) includes a positioning structure (31), which includes a positioning post (311) on the first mounting flange (111) and a positioning hole (312) on the second mounting flange (121). The positioning post (311) is used to pass through the positioning hole (312).
3. The filter assembly of claim 2, wherein, The detachable connection structure (3) further includes a locking structure (32), which includes a drive spring (323), a locking pin (321) slidably mounted on the second mounting flange (121), and a locking hole (322) radially penetrating the outer periphery of the positioning post (311). The drive spring (323) is connected between the locking pin (321) and the second mounting flange (121), and the elastic force of the drive spring (323) is used to drive the locking pin (321) to be inserted into the lock hole (322).
4. The filter assembly of claim 3, wherein, The second mounting flange (121) is provided with a locking pin groove (1211), one end of which is connected to the positioning hole (312), and the other end penetrates the surface of the second mounting flange (121) to form a locking pin inlet; The locking pin (321) includes a connected locking pin body (3211) and a limiting part (3212). The locking pin body (3211) is smaller than the size of the locking pin inlet so as to slide into the positioning hole (312) through the locking pin inlet and the locking pin groove (1211). The limiting part (3212) is located outside the locking pin groove (1211) and is larger than the size of the locking pin inlet.
5. The filter assembly of claim 2, wherein, The first mounting flange (111) and the second mounting flange (121) extend axially. The positioning pins (311) and the positioning holes (312) are multiple and arranged at intervals along the axial direction, and are arranged in a one-to-one correspondence.
6. The filter assembly of claim 1, wherein, A sealing strip (4) is provided between the corresponding end faces of the first cylindrical half shell (11) and the second cylindrical half shell (12) in the circumferential direction, and the sealing strip (4) extends axially.
7. The filter assembly of claim 6, wherein, The first cylindrical half-shell (11) and / or the second cylindrical half-shell (12) are provided with a sealing strip mounting groove (1111) extending along the axial direction on their circumferential end faces.
8. The filter assembly of claim 1, wherein, The inner peripheral wall of the water passage cavity (13) is provided with at least two filter element slots (131) spaced apart in the axial direction. The filter element slots (131) are used to engage the filter element (2) to restrict the axial movement of the filter element (2).
9. A water quality detection device, characterized by, include: Filter assembly (100) according to any one of claims 1-8; A housing (200) surrounds a receiving cavity for holding a water sample to be tested; The suction assembly (300) includes a corrugated pipe (51) and a water pump (52) connected together.
