Further, as shown in fig. 2, 3, 4 and 5, the driver 3 in the present embodiment is a motor, and may also be other devices capable of driving the object to rotate. In one implementation, the motor may be fixed to the housing 1 by means of the pressure piece 14 and screws. The driving assembly comprises a first threaded part 4 connected with the driver 3 and a second threaded part 5 fixed on the air purifying part 2 and in threaded connection with the first threaded part 4, and the driver 3 drives the first threaded part 4 to rotate so as to drive the air purifying part 2 to move linearly along the direction of extending out of or retracting into the shell 1 through the matched rotation of the first threaded part 4 and the second threaded part 5.
Specifically, continuing with fig. 2, 3, 4 and 5, the air purifying member 2 in this embodiment has opposite first and second ends, wherein the first end is toward the open end of the housing 1 and the second end is away from the open end of the housing 1. The second end of the air purifying part 2 is provided with a passage hole along the moving direction of the air purifying part 2, the shape of the passage hole is not unique, for example, the passage hole can be a half-barrel shape with the periphery in a half-closed state, or a barrel shape with the periphery in a fully-closed state, or, as in this embodiment, a part of the passage hole is located in the air purifying part 2 and is in a barrel shape, and another part is exposed outside and is in a half-barrel shape, and specifically, a part of the barrel-shaped passage hole extends to a direction away from the open end to form a half-barrel-shaped area, and the like. Further, the first screw member 4 is a threaded rod, which may be formed by screwing the driving rod of the driver 3, or may be formed separately. The second threaded part 5 has a thread for connection with a threaded rod, in particular a nut cap which can be semi-annular. One end of the threaded rod is connected with the driver 3, the other end of the threaded rod penetrates through a threaded hole of the nut cover to extend into the channel hole, and the threaded rod can move relative to the channel hole when the driver 3 drives the driver to rotate, namely when the driver 3 drives the threaded rod to rotate, the threaded rod drives the nut cover, so that the air purification piece 2 moves, and therefore the threaded rod can move relative to the channel hole.
Further, the air purifying piece 2 in this embodiment is further provided with a positioning structure, and the second screw 5 is fixedly connected with the air purifying piece 2 through the positioning structure.
As shown in fig. 4, the positioning structure in this embodiment includes a slot 6 formed on the air purifying member 2 and a first mounting portion 7, and specifically, the positioning structure may be disposed at the passage hole, and in this embodiment, the positioning structure may be optionally disposed on the half-barrel portion of the passage hole. Wherein, draw-in groove 6 and first installation department 7 correspond respectively and set up at the radial ascending both ends department in half barrel-shaped passage hole, and the concrete structure of draw-in groove 6 and first installation department 7 is indefinite, and for example draw-in groove 6 can be bar draw-in groove 6, square groove etc. and first installation department 7 can be buckle or mounting hole etc.. The second screw member 5 comprises a lug 8 which corresponds to the position of the clamping groove 6 and is matched with the structure of the clamping groove 6 to be clamped and abutted against the clamping groove 6, and a second mounting part which corresponds to the position of the first mounting part 7 and is matched and connected with the first mounting part 7. In this embodiment, the first mounting portion 7 and the second mounting portion both include a connecting hole, and the second mounting portion is further provided with a bolt, so that the second screw member 5 and the air purifying member 2 are stably connected through the bolt.
Optionally, in order to make the air cleaning element 2 more stable during movement, in this embodiment at least part of the walls of the housing corresponding to the side plates of the air cleaning element 2 in the receiving chamber are adapted to the side plate structure and abut against each other. For example, the side wall and the side plate of the chamber are both provided in an arc shape or the like to increase the contact area, which is more advantageous for limiting the position of the air purifying member 2 in the horizontal direction.
Further, as shown in fig. 6, a limiting mechanism for limiting the moving distance of the air purifying member 2 is further disposed in the accommodating chamber in the present embodiment.
This stop gear includes:
the first switch 9 is used for abutting against the air purifying piece 2 when one end of the air purifying piece 2 moves to a first position along the direction of extending out of the shell 1, and then is triggered;
the second switch 10 is used for abutting against the air purifying piece 2 when one end of the air purifying piece 2 moves to a second position along the direction of retracting into the shell 1, and then is triggered;
and the controller is electrically connected with the driving device, the first switch 9 and the second switch 10 respectively and is used for controlling the driving device to stop running when the first switch 9 or the second switch 10 is triggered.
Specifically, the first switch 9 and the second switch 10 in the present embodiment are both mechanical switches, and may also be micro switches or the like. If the second end of the air cleaning element 2, i.e. the end facing away from the open end of the housing 1, is provided with a passage hole as described above, the first switch 9 will abut against the air cleaning element 2 and be triggered when the air cleaning element 2 moves to the first position in the direction extending out of the housing 1. When the second end of the air purifying member 2 moves to the second position along with the air purifying member 2 in the direction of retracting into the housing 1, it will abut against the second switch 10, so that the second switch 10 is triggered. The first position is a position that the second end (located in the accommodating chamber) of the air purifying member 2 reaches when the air purifying member 2 reaches the maximum position after extending out of the housing 1, and the second position is a position that the second end of the air purifying member 2 can reach when the air purifying member 2 retracts into the housing 1 and returns to its initial state, for example, a position that the second end of the air purifying member 2 can reach when the air purifying member 2 is completely retracted into the housing 1. The first switch 9, the second switch 10 and the driver 3 are all electrically connected to the circuit board of the controller at the same time, and when the first switch 9 and the second switch 10 are triggered respectively, the controller will control the driver 3 to stop driving, so that the air purifying member 2 can stay at the first position or the second position and does not move continuously along the original direction.
Alternatively, in another implementation, when the first switch 9 is triggered and the second switch 10 is not triggered, the air purifying member 2 can be considered to move to the first position in a direction to extend out of the housing 1. When the second switch 10 is activated and the first switch 9 is not activated, it can be considered that the air cleaning member 2 moves to the second position in the direction of retracting into the housing 1. In this way, the accuracy of the controller for controlling the driver to stop driving can be further improved.
Through setting up first switch and second switch, whether the air purification spare stretches out and retracts to target in place at accurate judgement air purification spare with the mode of mechanical spacing. In the mass production of the air purifier, the realization mode is more favorable for controlling the consistency of products. In addition, the air purification piece rocks when flexible and reduces, and is more stable, can reduce first switch and second switch miss the probability of detecting signal, and the two cooperation is more favorable to air purification piece to stretch out and draw back stably, accurately.
Further, as shown in fig. 7, a bar-shaped groove 11 is formed in a side plate of the air purifying member 2 in the embodiment along a moving direction of the air purifying member 2, a length of the bar-shaped groove 11 may be greater than a maximum stroke of the air purifying member 2, or one end of the bar-shaped groove is open, and the other end is closed, etc., the first switch 9 is disposed corresponding to the bar-shaped groove 11, and at least a portion of the first switch 9 extends into the bar-shaped groove 11, for example, at least a trigger portion (e.g., a switch lever, etc.) of the first switch 9 is located in the bar-shaped groove 11. When the second end of the air purifying member 2 moves to the first position, the first switch 9 abuts against one end or the closed end of the strip-shaped groove 11 in the same direction as the air purifying member 2, and is triggered. And when the second end of air purification spare 2 moved to the second position, the second end of air purification spare 2 offseted with second switch 10, and then triggered second switch 10, can set up second switch 10 in the accommodation chamber on the chamber wall relative with the dorsal part of air purification spare 2 during specific application, or set up in the curb plate with air purification spare 2 and correspond the position department, it is specific indefinite.
Optionally, in order to prevent the air purifying member 2 from protruding out of the housing 1, the first switch 9 is not triggered, or the first switch 9 is triggered, but the controller fails to receive the trigger signal, and thus fails to control the driver 3 to stop driving in time, so as to cause a phenomenon that the air purifying member 2 slips, the air purifying member 2 in this embodiment is provided with an anti-dropping structure in cooperation with the accommodating chamber, and the anti-dropping structure is used for limiting a maximum stroke of the air purifying member 2 moving in a direction of protruding out of the housing 1. Through such a mode, even if first switch has missed the detected signal, the stopper offsets with the face that blocks of spacing groove, also can block air purification piece and continue to stretch out to further ensure air purification piece can not the slippage at the in-process that stretches out.
Specifically, the retaining structure is not exclusive as long as the retaining effect can be achieved, and for example, a stopper or the like is provided in cooperation between the housing 1 and the air purifying member 2. Also as in this embodiment, as shown in fig. 8, the anti-disengaging structure in this embodiment includes a limiting groove 12 disposed on the air purifying member 2 and a limiting block 13 correspondingly disposed in the accommodating chamber and located in the limiting groove 12, where the limiting groove 12 is a strip-shaped long groove, and the length direction of the limiting groove 12 is the same as the moving direction of the air purifying member 2, and when the air purifying member 2 is located in the casing 1, the distance between the limiting block 13 and one end of the limiting groove 12 close to the open end of the casing 1 is the maximum moving distance, i.e., the maximum stroke, of the air purifying member 2. When the second end of the air purifying member 2 moves to the first position along the direction extending out of the casing 1, the limiting block 13 moves along the limiting groove 12 until the limiting groove 12 and the end of the limiting groove 12 close to the open end of the casing 1 are mutually clamped, at this time, even if the driver 3 continues to drive, the air purifying member 2 cannot slip out of the casing 1, and the moving position of the air purifying member 2 is more effectively limited.
