[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The present invention is further described in detail below in conjunction with the embodiments.

[0024] A specific embodiment of a quick-disassembly deodorizing drain provided by the utility model:

[0025] like Figure 1 and Figure 2 As shown, the quick-detachable anti-odor water drainer includes a water drain seat 1, an inner water pipe 2, a connecting seat 3 and an outer sleeve 4. The connecting seat 3 is installed at the upper end of the outer sleeve 4, and a guide elbow 5 is installed at the lower part of the outer sleeve 4. The inner water pipe 2 is installed on the connecting seat 3. The inner water pipe 2 is provided with an external thread, and the inner water pipe 2 extends into the outer sleeve 4. The water drain seat 1 is installed at the upper end of the inner water pipe 2, and a magnetic flap assembly 6 is also provided at the connection between the outer sleeve 4 and the guide elbow 5. The magnetic flap assembly is an existing conventional technology, which is mainly used to prevent odor or insects from entering the inner water pipe 2, and plays a role in preventing insects and odor.

[0026] The inner water pipe 2 of this embodiment can be quickly disassembled and installed on the connecting seat 3. The specific structure is as follows: Figure 3-8 As shown, the connecting seat 3 includes an upper seat body 7 and a lower seat body 8, the lower seat body 8 is installed on the upper end of the outer sleeve 4, the inner wall of the lower seat body 8 is fixed with an annular plate 9, the upper surface of the annular plate 9 is fixed with a docking sleeve 10, the outer wall of the docking sleeve 10 and the inner wall of the lower seat body 8 form a mounting cavity, the inner wall of the docking sleeve 10 is fixed with six clamping edges 11, the outer wall of the clamping edge 11 is a circular arc transition structure, it should be noted that the docking sleeve 10 can be a complete circular sleeve body, or it can be two semicircular shapes, and the attached drawings of this embodiment show two semicircular shapes;

[0027] The lower part of the upper seat body 7 is installed in the installation cavity of the lower seat body 8, and the upper seat body 7 can rotate in the installation cavity. In order to realize the installation of the above-mentioned upper seat body 7, the upper seat body 7 of this embodiment is installed in the installation cavity of the lower seat body 8 through a rotating assembly. The rotating assembly includes a snap ring 12 and a plurality of snap blocks 13. The snap ring 12 is arranged at the lower end of the upper seat body 7. All the snap blocks 13 are fixed to the inner wall of the installation cavity of the lower seat body 8. All the snap blocks 13 are arranged along the circumferential direction. The outer edge of the snap ring 12 is a conical structure, and the inner wall of the snap block 13 is a circular arc transition structure. The snap ring 12 is located between the snap block 13 and the annular plate 9 (such as Figure 4 As shown), when installing, press the upper seat body 7 downwards. Due to the conical structure of the outer edge of the snap ring 12 and the arc transition structure of the inner wall of the clamping block 13, the snap ring 12 can slide down along the inner wall of the clamping block 13 smoothly and finally enter between the clamping block 13 and the annular plate 9. At this time, the upper seat body 7 can rotate freely 360° on the lower seat body 8. The setting of the snap ring 12 prevents the upper seat body 7 from escaping upward from the lower seat body 8.

[0028] Six arc-shaped connecting plates 14 are arranged inside the upper seat body 7, and the two ends of the arc-shaped connecting plates 14 are respectively an inner end and an outer end. The upper inner end of the arc-shaped connecting plates 14 is fixed to the inner wall of the upper seat body 7 by a short plate 15. Under normal circumstances, the inner end of the arc-shaped connecting plates 14 is closer to the axis of the upper seat body 7, while the outer end of the arc-shaped connecting plates 14 is relatively farther from the axis of the upper seat body 7. A rectangular notch 16 is formed between the lower inner end of the arc-shaped connecting plates 14 and the inner wall of the upper seat body 7. When the upper seat body 7 is installed on the lower seat body 8, the docking sleeve 10 is located between the lower part of the arc-shaped connecting plates 14 and the inner wall of the upper seat body 7, and the docking sleeve 10 passes through all the rectangular notches 16.

[0029] All arc-shaped connecting plates 14 are arranged one by one with the clamping edges 11, and the inner wall of each arc-shaped connecting plate 14 is provided with a thread segment 17, and all the thread segments 17 are combined to form an internal thread, which is adapted to the external thread on the inner water pipe 2;

[0030] The thickness of the arc-shaped connecting plate 14 gradually increases from the inner end to the outer end. The outer wall of the outer end of the arc-shaped connecting plate 14 is provided with a vertical clamping groove 18 , which matches with the corresponding clamping edge 11 .

[0031] The installation steps of the inner water pipe 2 are as follows: insert the inner water pipe 2 into the connecting seat 3 and the outer sleeve 4, then rotate the upper seat body 7 clockwise, the clamping edge 11 slides along the outer wall of the arc-shaped connecting plate 14, at this time, the clamping edge 11 will push the arc-shaped connecting plate 14 in the axial direction, and the arc-shaped connecting plate 14 will be slightly deformed around the inner end, and finally the clamping edge 11 enters the vertical clamping groove 18 at the outer end of the arc-shaped connecting plate 14, and the clamping edge 11 and the vertical clamping groove 18 form a clamping state (as shown in Figure 3), at this time, the inner walls of all the arc-shaped connecting plates 14 are located on the same circle, and all the arc-shaped connecting plates 14 lock the inner water pipe 2 in the middle;

[0032] In addition to the above-mentioned installation method, the inner water pipe 2 can also be installed in a post-installation manner, for example, the upper seat body 7 is rotated clockwise so that the edge 11 enters the vertical groove 18. At this time, the thread segments 17 of all the arc-shaped connecting plates 14 form internal threads, and then the inner water pipe 2 is screwed on the connecting seat 3, and the external thread of the inner water pipe 2 forms a threaded connection with the internal thread; in addition, in order to facilitate the operator to know that the edge 11 has successfully entered the vertical groove 18, six limiting edges 19 are arranged on the inner wall of the docking sleeve 10, and the limiting edges 19 are arranged one by one with the edge 11, and the limiting edges 19 are adjacent to the corresponding edge 11. When the edge 11 enters the vertical groove 18, the limiting edges 19 just hit the rectangular notch 16, and the upper seat body 7 cannot continue to be rotated clockwise.

[0033] The disassembly steps of the inner water pipe 2 are as follows: rotate the upper seat 7 counterclockwise, the clamping edge 11 disengages from the vertical clamping groove 18, the clamping edge 11 releases the deformation restriction on the arc-shaped connecting plate 14, and the arc-shaped connecting plate 14 gradually recovers the deformation around the inner end. At this time, the arc-shaped connecting plate 14 cannot hold the inner water pipe 2, and the inner water pipe 2 can be pulled out upward.

[0034] The lower seat body 8 of this embodiment can also be quickly installed using a rotating assembly. Specifically: a clamping ring 12 is arranged at the lower end of the lower seat body 8, all the clamping blocks 13 are fixed to the upper inner wall of the outer sleeve 4, all the clamping blocks 13 are arranged along the circumferential direction, and the upper inner wall of the outer sleeve 4 is provided with a stepped inner groove 20, and the clamping ring 12 is located between the clamping block 13 and the stepped inner groove 20.

[0035] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
