It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0037] like Figure 1 to Figure 2 , Figure 8 As shown in FIG. 11 , a structure diagram of a hands-free filter water cup provided by an embodiment of the utility model includes:

[0038] The filter screen 6 is detachably mounted in the cup body 10;

[0039] A cover body 1 connected to a cup body 10;

[0040] The rotary expansion locking assembly is installed on the cover body 1 and cooperates with the filter screen 6. The rotary expansion locking assembly is rotated to squeeze the elastic sealing sleeve 5, forcing the elastic sealing sleeve 5 to expand radially to lock the filter screen 6. The rotary expansion locking assembly is rotated in the reverse direction, the elastic sealing sleeve 5 returns to its original state, and the filter screen 6 is unlocked.

[0041] In one embodiment of the utility model, the hands-free filter water cup is provided with a rotation expansion locking assembly to solve the problems in the prior art, wherein the filter 6 and the cup body 10 are detachably connected in a limited position, and the rotation expansion locking assembly is used to control the state of the filter 6. When the filter 6 is rotated to squeeze the elastic sealing sleeve 5, the elastic sealing sleeve 5 radially expands to lock the filter 6, and the connection between the filter 6 and the cup body 10 can be overcome at this time. When the cover body 1 is unscrewed, the filter 6 can be unscrewed together with the cover body 1, and when the elastic sealing sleeve 5 is rotated in the reverse direction until the elastic sealing sleeve 5 returns to its original state, the filter 6 remains connected to the cup body 10, and when the cover body 1 is unscrewed at this time, the filter 6 remains in the cup body 10;

[0042] The cover body 1 is movably connected to the cup body 10, and a threaded connection or the like can be selected. The filter screen 6 is limitedly and detachably connected to the cup body 10. At the same time, the filter screen 6 is circumferentially nested inside the cover body 1, and the upper end surface of the filter screen 6 conflicts with the inner end surface of the cover body 1.

[0043] As shown in the cup body 10 to the anti-rotation rib 11, as a preferred embodiment of the present utility model, the filter screen 6 is provided with an elastic portion 61, which cooperates with the convex rib 101 on the cup body 10, and the filter screen 6 is elastically clamped on the cup body 10 through the cooperation of the elastic portion 61 and the convex rib 101;

[0044] The filter screen 6 is provided with a convex rib 62, which cooperates with the elastic sealing sleeve 5 in the rotation expansion locking assembly.

[0045] An elastic portion 61 is provided on the filter 6, and convex ribs 101 are distributed on the circumference of the inner wall of the cup body 10. The elastic snap connection between the filter 6 and the cup body 10 can be achieved through the cooperation of the elastic portion 61 and the convex ribs 101. At the same time, a convex rib 62 is distributed on the inner wall of the filter 6, which cooperates with the elastic sealing sleeve 5 in the rotary expansion locking assembly to achieve locking of the filter 6.

[0046] like Figure 2 , Figure 7 As shown in the cup body 10 to the anti-rotation rib 11 in FIG, as another preferred embodiment of the utility model, the rotation expansion locking assembly includes:

[0047] The rotating member 2 is mounted on the cover body 1;

[0048] The rotating connecting member 3 is fixedly connected to the rotating member 2. The rotating member 2 and the rotating connecting member 3 are integrally movably connected to the cover body 1. The rotating connecting member 3 is provided with a protrusion 31.

[0049] The sliding member 4 is installed between the cover body 1 and the rotating connecting member 3, and is vertically slidably matched with the cover body 1. The sliding member 4 is circumferentially provided with an annular waist groove 41, and the annular waist groove 41 is an inclined surface structure with an inclination. Positioning grooves 42 are provided at both ends of the annular waist groove 41. The protrusion 31 cooperates with the positioning groove 42. The rotating member 2 is rotated to drive the protrusion 31 to slide in the annular waist groove 41, and move from the positioning groove 42 at one end to the positioning groove 42 at the other end, thereby driving the sliding member 4 to slide up and down along the cover body 1;

[0050] The elastic sealing sleeve 5 is installed between the cover body 1 and the sliding member 4, and its two ends are in contact with the cover body 1 and the sliding member 4. When the sliding member 4 slides upward, it squeezes the elastic sealing sleeve 5, forcing the elastic sealing sleeve 5 to expand radially, and cooperate with the convex rib 62 to lock the filter 6. When the sliding member 4 slides downward, the elastic sealing sleeve 5 returns to its original state, and the filter 6 is unlocked.

[0051] The rotating member 2 is fixedly connected to the rotating connecting member 3 without relative rotation, and the whole body rotates with the cover body 1. The sliding member 4 is circumferentially nested between the cover body 1 and the rotating connecting member 3, and axially connected to the cover body 1 by sliding up and down. The elastic sealing sleeve 5 is nested in the annular space between the cover body 1 and the sliding member 4, and the two ends are respectively in conflict with the cover body 1 and the sliding member 4. The lower end surface of the sliding member 4 is provided with a plurality of annular waist grooves 41 evenly distributed along the circumference. The annular waist groove 41 is an inclined structure with an inclined angle, and positioning grooves 42 are provided at both ends. The upper end surface of the rotating connecting member 3 is correspondingly provided with a plurality of protrusions 31 evenly distributed along the circumference, and the top of the protrusion 31 is dome-shaped. The specific principle of locking or unlocking by rotation is as follows:

[0052] The rotating member 2 rotates a certain angle, driving the rotating connecting member 3 to rotate relative to the sliding member 4. The protrusion 31 is in the annular waist groove 41, from the positioning groove 42 at one end, through the inclined structure, and rotates and slides to the positioning groove 42 at the other end, and is positioned, thereby driving the sliding member 4 to slide upward relative to the cover body 1, forcing the elastic sealing sleeve 5 to compress, deform, and expand radially. In this state, the maximum outer diameter of the elastic sealing sleeve 5 is greater than the inner diameter of the rib 62, and it conflicts with the lower step surface of the rib 62, and the filter screen 6 is locked with the cover body 1. At this time, the cover body 1 is unscrewed, overcoming the elastic clamping of the filter screen 6 and the cup body 10, and the filter screen 6 is unscrewed together with the cover body 1;

[0053] The rotating member 2 is rotated in the opposite direction by the same angle, driving the rotating connecting member 3 to rotate relative to the sliding member 4. The protrusion 31 is in the annular waist groove 41, from the positioning groove 42 at the other end, through the inclined structure, and rotates and slides to the positioning groove 42 at one end, and is positioned, driving the sliding member 4 to slide downward relative to the cover body 1, and the deformation of the elastic sealing sleeve 5 is completely restored. In this state, the maximum outer diameter of the elastic sealing sleeve 5 is smaller than the inner diameter of the rib 62, and the filter screen 6 is separated from the cover body 1. At this time, the cover body 1 is unscrewed, and the filter screen 6 is elastically engaged with the cup body 10 and retained in the cup body 10.

[0054] like Figure 3 , Figure 6 As shown, as a preferred embodiment of the utility model, the cover body 1 is provided with a rotation-stopping rib 11, which cooperates with a rotation-stopping groove 43 provided on the sliding member 4 to prevent the sliding member 4 from rotating.

[0055] Through the cooperation of the anti-rotation rib 11 and the anti-rotation groove 43, the sliding member 4 can only slide up and down. The cover body 1 is also provided with a contact rib 12. When the sliding member 4 cooperates with the cover body 1, intermittent sliding cooperation can be achieved through the contact rib 12 to avoid surface contact and cause poor sliding.

[0056] like Figures 4 to 5 As shown, as a preferred embodiment of the utility model, the rotating member 2 is provided with a second anti-rotation rib 21, which cooperates with a second anti-rotation groove 32 provided on the rotating connecting member 3 to drive the rotating member 2 and the rotating connecting member 3 to be fixedly connected.

[0057] The fixed connection between the rotating member 2 and the rotating connecting member 3 is achieved by the cooperation between the second anti-rotation rib 21 and the second anti-rotation groove 32 . Rotating the rotating member 2 can drive the rotating member 2 and the rotating connecting member 3 to rotate together.

[0058] like Figure 2 As shown in the cup body 10 to the anti-rotation rib 11 in FIG, as a preferred embodiment of the utility model, it also includes:

[0059] A sealing member 7, mounted on the cover body 1;

[0060] A second sealing member 8, mounted on the rotating member 2;

[0061] The sealing member 3 9 is installed on the cover body 1 and cooperates with the cup body 10.

[0062] Seal 1 7 is arranged at the upper end of the cover body 1, seal 2 8 is arranged at the lower end of the rotating member 2, and is used to seal the cavity between the cover body 1 and the rotating member 2, and seal 3 9 is arranged on the cover body 1 to achieve a sealing effect between the cover body 1 and the cup body 10.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
