[0009] Furthermore, the lower protrusion is integrally formed on the lower surface of the lower flip cover; and filter holes are provided on the lower flip cover and the side wall of the filter basket.

[0010] Furthermore, a bouncing assembly is fixedly arranged in the filter basket, a water-sealing cover is arranged at the upper end of the bouncing assembly, and a water-sealing rubber strip is arranged at the side edge or the lower edge of the water-sealing cover; the water-sealing cover has a water-sealing state or a drainage state under the drive of the bouncing assembly, and in the water-sealing state, the water-sealing cover completely covers the upper opening of the outer shell; a button is arranged at the upper end of the locking hook mechanism; the button is close to the side of the bouncing assembly and is slidably fitted with the bouncing assembly.

[0011] Furthermore, the filter basket is formed with guide blocks on both sides of the button at the upper end, and an inclined surface is formed on a side of the guide block away from the button, and the inclined surface gradually moves away from the button from top to bottom.

[0012] Furthermore, the locking hook mechanism includes a vertical sliding shaft, a horizontal hook, a vertical spring and a horizontal spring; a vertical sliding cavity is provided in the filter basket, the vertical sliding shaft is slidably provided in the vertical sliding cavity, and the vertical spring is sleeved on the vertical sliding shaft to press against the vertical sliding shaft from bottom to top; a horizontal sliding cavity is provided at the lower part of the vertical sliding shaft, the horizontal hook is slidably provided in the horizontal sliding cavity, and the horizontal spring is sleeved on the horizontal hook so that the horizontal hook presses against the downward flip cover; a guide slope is formed on the head of the horizontal hook, and a locking surface is formed on the horizontal hook above the guide slope; a limiting buckle is formed on the tail of the horizontal hook.

[0013] Furthermore, a reduced diameter cavity is formed in the vertical sliding cavity, and the upper end and lower end of the reduced diameter cavity are respectively formed with an upper abutting top surface and a lower abutting top surface; the vertical sliding shaft includes an upper section, a middle section and a lower section; the middle section passes through the reduced diameter cavity; the upper section and the middle section are threadedly connected, and the middle section and the lower section are threadedly connected; the vertical spring is sleeved on the middle section, the upper end of the vertical spring abuts the lower end surface of the upper section, and the lower end of the vertical spring abuts on the upper abutting top surface.

[0022] Fourth, the locking hook mechanism primarily consists of a vertical sliding shaft and a horizontal hook. When unlocking, the vertical sliding shaft passively moves downward, causing the horizontal hook to move downward and disengage from the lower flip cover. When closing, the lower flip cover rotates upward under the abutment of the lower protrusion. After contacting the guide slope, the horizontal hook moves backward until it passes the horizontal hook, causing the locking surface to engage the lower surface of the lower flip cover.

[0023] 5. The outer shell can be a drain shell placed in the drain outlet of a sink, or a floor drain shell. The utility model can be designed to be used in different drainage structures.

[0024] Compared with the prior art, the present invention provides a lower flip cover, a locking hook mechanism and a lower protrusion for easy unlocking and re-locking, which greatly facilitates the user to clean the dirt in the filter basket. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0041] like Figures 1 to 7 As shown, as the first embodiment of the present invention, it is a quick-open flip-cover drainer involved in the present invention, comprising an outer shell 1, a filter basket 2, a lower flip cover 21 and a locking hook mechanism 3, wherein the lower flip cover 21 is rotatably connected to one side of the bottom of the filter basket 2, and the locking hook mechanism 3 is provided on the filter basket 2 to hook the lower flip cover 21 or unlock the lower flip cover 21; the filter basket 2 is detachably placed in the outer shell 1; a lower protrusion 211 is provided on the lower surface of the lower flip cover 21; when the locking hook mechanism 3 hooks the lower flip cover 21, the lower end of the lower protrusion 211 is lower than the lowest point of the locking hook mechanism 3.

[0042] Thus, in the quick-opening flip-top drainer of the present invention, when the filter basket 2 needs to be cleaned, the filter basket 2 is removed from the outer shell 1, and the locking hook mechanism 3 unlocks the lower flip cover 21. The lower flip cover 21 then flips open under the action of gravity, allowing the accumulated dirt in the filter basket 2 to fall out and be discharged. When the lower flip cover 21 needs to be closed, the lower protrusion 211 of the lower flip cover 21 abuts against a fixed surface, such as the bottom of a sink or other suitable platform, to unlock the lower flip cover 21. Preferably, the lower protrusion 211 is integrally formed on the lower surface of the lower flip cover 21; and filter holes are provided on the sidewalls of the lower flip cover 21 and the filter basket 2.

[0043] Preferably, a bouncing assembly 22 is fixedly provided in the filter basket 2. A water-sealing cover 221 is provided at the upper end of the bouncing assembly 22. A water-sealing rubber strip 222 is provided at the side edge or the lower edge of the water-sealing cover. Driven by the bouncing assembly 22, the water-sealing cover 221 has a water-sealing state or a water-draining state. In the water-sealing state, the water-sealing cover completely covers the upper opening of the outer shell 1. A button 35 is provided at the upper end of the locking hook mechanism 3. The button 35 is slidably fitted with the side of the bouncing assembly 22 near the side of the bouncing assembly 22. By providing the bouncing assembly 22, water sealing and drainage of the drain can be achieved. In the water-sealing state, water can be stored in the sink to facilitate washing items. The bouncing assembly 22 can be a ballpoint pen bouncing structure or a hook slide type bouncing structure.

[0044] Preferably, the filter basket 2 is formed with guide blocks 23 on either side of the button 35 at its upper end. The guide blocks 23 have inclined surfaces 231 on their sides facing away from the button 35, with the inclined surfaces 231 gradually extending away from the button 35 from top to bottom. The design of the guide blocks 23 and the fit between the button 35 and the spring assembly 22 are designed to reduce the risk of hair getting caught on the button 35. Solid debris is guided to the sides by the inclined guide blocks 23, and then enters the filter basket 2 downward.

[0045] Preferably, the locking hook mechanism 3 includes a vertical sliding shaft 31, a horizontal hook 32, a vertical spring 33, and a horizontal spring 34. A vertical sliding cavity 24 is provided in the filter basket 2, in which the vertical sliding shaft 31 slides. The vertical spring 33 is sleeved on the vertical sliding shaft 31 to press against the vertical sliding shaft 31 from bottom to top. A horizontal sliding cavity 30 is provided below the vertical sliding shaft 31, in which the horizontal hook 32 slides. The horizontal spring 34 is sleeved on the horizontal hook 32 to force the horizontal hook 32 against the downward flip cover 21. A guide slope 321 is formed at the head of the horizontal hook 32, and a locking surface 322 is formed on the horizontal hook 32 above the guide slope 321. A limit buckle 323 is formed at the tail of the horizontal hook 32. The limit buckle 323 limits the maximum forward movement of the horizontal hook 32.

[0046] The locking hook mechanism 3 is primarily composed of a vertical sliding shaft 31 and a horizontal hook 32, which are separately provided. When unlocking, the vertical sliding shaft 31 passively moves downward, causing the horizontal hook 32 to move downward and disengage from the lower flip cover 21. When closing, the lower flip cover 21 rotates upward under the action of the lower protrusion 211. After contacting the guide slope 321, the horizontal hook 32 moves backward until it passes over the horizontal hook 32, causing the locking surface 322 to engage the lower surface of the lower flip cover 21. Specifically, a reduced diameter cavity 241 is formed in the vertical sliding cavity 24. An upper abutting top surface 242 and a lower abutting top surface 243 are formed at the upper and lower ends of the reduced diameter cavity 241, respectively. The vertical sliding shaft 31 includes an upper section 311, a middle section 312, and a lower section 313. The middle section 312 passes through the reduced diameter cavity 241. The upper section 311 and the middle section 312 are threadedly connected, and the middle section 312 and the lower section 313 are threadedly connected. The vertical spring 33 is sleeved on the middle section 312. The upper end of the vertical spring 33 abuts the lower end surface of the upper section 311, and the lower end of the vertical spring 33 abuts the upper abutting top surface 242. The lower abutting top surface 243 limits the maximum upward movement of the lower section 313.

[0047] like Figures 8 to 13 As shown in FIG. 2 , as a second embodiment of the present invention, the filter basket 2 is further provided with a handle 26 to facilitate picking up the filter basket 2. In this embodiment, the upper end of the vertical sliding shaft 31 is used as a button 35.

[0048] like Figures 14 to 16As shown, as the third embodiment of the present invention, preferably, a card edge 25 is formed on the upper edge of the filter basket 2; preferably, the outer shell 1 is a floor drain shell, and the floor drain shell has a concave water collection chamber 12, and the bottom of the water collection chamber 12 is provided with a support ring 251 for supporting the card edge 25. Furthermore, an anti-odor structure 11 is provided at the lower part of the outer shell 1. Specifically, the anti-odor structure 11 is an anti-odor flap. The outer shell 1 can be a drain shell placed in the drain outlet of the sink, or it can be a floor drain shell (such as Figures 14 to 16 As shown), the utility model can be designed to be matched with different launching structures.

[0049] Compared with the prior art, the present invention provides a lower flip cover 21 , a locking hook mechanism 3 and a lower protrusion 211 to facilitate unlocking and re-locking, which greatly facilitates the user to clean the dirt in the filter basket 2 .

[0050] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
