[0043] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] Example 1, as Figures 1-3 As shown, a drain cleaner includes a hair-cutting mechanism 1, which comprises a spring-loaded valve core 4, an intercepting platform 7, and a cutter 9. The spring-loaded valve core 4 includes a moving end 5 and a fixed end 6. A pressing cover 2 is provided on the upper part of the moving end 5 for the user to press and drive the hair-cutting mechanism 1 to move. An annular sealing part 3 is provided on the lower part of the pressing cover 2 for sealing the drain outlet around the drain cleaner.

[0045] like Figures 1-3 As shown, the interceptor 7 is located below the fixed end 6 of the spring valve core 4. Several blocking parts 8 are arranged around the periphery of the interceptor 7. These blocking parts 8 are used to intercept hair, preventing it from directly entering the drain pipe and causing blockage. A gap is provided between adjacent blocking parts 8 to allow water flow, thus facilitating the entry of debris and water into the drain pipe through the gap.

[0046] Combination Figure 3 and Figure 5The cutter 9 is located at the moving end 5 of the spring valve core 4 and can be displaced in the vertical direction. When the cutter 9 moves downward to the set position, the cutter 9 engages with the blocking part 8 to cut the hair, thereby cutting the hair into multiple segments and allowing it to flow into the drain pipe through the gaps between the blocking parts 8, reducing the possibility of drain pipe blockage.

[0047] The connection between the interceptor 7 and the spring valve core 4 can be achieved through snap-fit, threaded connection, etc., such as... Figure 2 As shown, in this embodiment, the lower part of the fixed end 6 of the spring valve core 4 is provided with a threaded post 16, and the intercepting platform 7 is fitted on the threaded post 16 and locked by a nut 23.

[0048] Combination Figure 2 , Figure 3 and Figure 5 The blocking part 8 is provided with a ramp section 10 that gathers hair. The inclined ramp section 10, under the action of gravity, concentrates the hair on its lower side, facilitating hair cutting and flushing into the drain pipe. Specifically, the blocking part 8 extends obliquely upwards and outwards to form the ramp section 10.

[0049] Combination Figure 3 and Figure 5 The cutter 9 includes several radially arranged blade portions 11, which are attached to one side of the blocking portion 8, thereby achieving shearing cooperation through the up-and-down movement of the blade portions 11 and their attachment to one side of the blocking portion 8.

[0050] Combination Figure 3 and Figure 5 The blade section 11 is provided with a shearing section 12 that extends obliquely outward. Thus, by cooperating with the obliquely extending shearing section 12 and the obliquely upward and outward extending ramp section 10, oblique compression shearing of hair can be achieved, and the blade can cut by sliding relative to the hair, thereby making the cutting more labor-saving and effective.

[0051] Combination Figure 7 and Figure 8 When the cutter 9 moves downward to the set position, the outer side of the blade portion 11 cooperates with the blocking portion 8 to form a closed cutting space 100, that is, the lower edge 101 of the blade and the upper edge 102 of the blocking portion surround and form the cutting space 100; during the downward cutting process of the cutter 9, the cutting space 100 gradually shrinks. The hair is located within the cutting space 100. When the cutting space 100 gradually shrinks to be completely closed, that is, when the area is 0, the edges of the cutter 9 and the blocking portion 8 completely overlap, realizing the cutting of the hair.

[0052] like Figure 7As shown, the blade portion 11 is inclined at an angle to the corresponding blocking portion 8, so that when the cutter 9 moves downward, the end A of the blade portion 11 first abuts against the blocking portion 8, thereby closing the upper end of the shearing space 100, so that the hair can only move downward when being pressed by the blade portion 11 and the blocking portion 8, and the lower end B of the blade portion 11 abuts against the blocking portion 8 to close the lower end of the shearing space 100, so that the hair is always in the shearing space 100 and cannot be pressed to move upward out of the shearing space 100, thereby ensuring that the hair can always be cut by the blade portion 1 and be sheared, and the shearing effect is better, which is more conducive to hair cleaning.

[0053] In combination Figure 1 With Figure 5 , the blade portion 11 of the cutter 9 extends downward to form a guide portion 13, the lower end of the guide portion 13 extends into the gap between the corresponding two blocking portions 8 and abuts against the side portion of one of the blocking portions 8, so that the movement of the blade portion 11 is guided by the guide portion 13, and the blade portion 11 can accurately enter the gap between the two blocking portions 8, avoiding direct contact between the blade of the blade portion 11 and the blocking portion 8, which can damage the blade portion 11 or the blocking portion 8, thereby ensuring the service life of the blade portion 11.

[0054] Further, in combination Figure 1 , Figure 2 With Figure 5 , the plurality of blocking portions 8 enclose a first circular table region 14, and the shearing sections 12 of the plurality of blade portions 11 enclose a second circular table region 15, and the second circular table region 15 is located at the upper portion of the first circular table region 14, so that when the user presses the pressing cover 2, the second circular table region 15 can be driven as a whole to cooperate with the first circular table region 14, thereby enabling the plurality of blade portions 11 and the blocking portions 8 to simultaneously complete shearing cooperation, which can simultaneously process hair at multiple positions and is more efficient. Meanwhile, the circular table design can simplify the shape and save the corresponding installation space while ensuring the realization of the related functions. Meanwhile, by increasing the number of the blade portions 11 of the cutter 9, the size of the cut hair can be reduced, the brush can be more easily flushed down the sewer pipe, and the possibility of sewer pipe blockage can be further reduced.

[0055] Next, the specific structure of the bounce valve core 4 will be described in detail. As shown in Figure 4As shown, the rebound valve core 4 comprises a support rod 17, a connecting piece 18 for connecting the pressing cover 2 is arranged on the support rod 17, and an elastic piece 19 is arranged between the connecting piece 18 and the support rod 17, so that the pressing cover 2 and the connecting piece 18 can be reset through the elastic piece 19. The support rod 17 is further provided with a clamping block 20, the threaded column 16 described above can be formed at the lower end of the clamping block 20, and a groove 21 is further arranged on the clamping block 20. The connecting piece 18 is further provided with a clamping hook 22, one end of which is fixed in the connecting piece 18, and the other end is arranged in the groove 21 of the clamping block 20, and moves up and down with the connecting piece 18. When the pressing cover 2 moves up and down, the clamping hook 22 moves up and down with the pressing cover 2, and at the same time, the other end of the clamping hook 22 is hooked at different positions of the groove 21 to realize the fixation of the pressing cover 2 when the pressing cover 2 moves up and down, thereby realizing the closing or opening of the sealing part 3 at the lower part of the pressing cover 2 to the drain hole on which the drain is installed.

[0056] Further, the moving end 5 of the rebound valve core 4 can be further provided with a plurality of pressing plates, and the plurality of blocking parts 8 also surround the circular table region and move with the elastic piece 19. The pressing plates can directly abut against the blocking parts 8, so as to realize the compression of the hair and facilitate the cutting of the hair cutter 9.

[0057] Embodiment two, as Figures 6-7 shown, the cutter 9 comprises a middle mounting table 30, a plurality of embedding grooves 31 are arranged on the peripheral side of the mounting table 30, and blades 32 are arranged in the embedding grooves 31; the outer side of the blade 32 forms the blade part 11; and the mounting table 30 and the moving end of the rebound valve core 4 are fixedly connected.

[0058] Combined Figure 6 with Figure 7 , the embedding groove 31 is provided with a positioning hole (not shown), and the inner side of the blade 32 is provided with a branch part 33 extending into the positioning hole. In this embodiment, the positioning hole and the branch part 33 are both vertically arranged, so as to realize the pre-positioning of the blade 32 on the mounting table through the cooperation between the branch part 33 and the blade 32 and the embedding groove 31, and make the blade 32 accurately cooperate with the blocking part 8 to realize the accurate cutting of the hair.

[0059] As Figure 6 shown, the upper part of the mounting table 30 is sleeved with a clamping ring 39, and the clamping ring 39 fixes the upper part of the blade 32; the cooperation structure of the clamping ring 39 and the mounting table 30 is that the outer side of the top of the mounting table is provided with a ring tooth part 38, and the inner side of the clamping ring 39 is provided with a clamping groove part 41 corresponding to the ring tooth part 38.

[0060] The blade 32 is loaded into the mounting table 30 from bottom to top, the branch part is inserted into the mounting table, so that the lower part of the blade 32 cannot be turned outwards, and the design of the clamping ring 39 makes the upper part of the blade 32 cannot be separated, so that the fixing effect of the blade 32 is good, and the assembly is convenient.

[0061] As Figure 6 shown, when installing the hoop 39, only need to align the card slot part 41 with the ring tooth part 38, the hoop 39 can be put into the ring groove 35 at the top of the installation platform 30, the convex part 40 is formed between the two card slot parts 41, the convex part 40 corresponds to the recess 37, after the hoop 39 is slightly rotated, the convex part 40 is clamped at the lower side of the ring tooth part 38, preventing the hoop 39 from being separated; the hoop 39 is fixed on the installation platform 30 through the bolt 42.

[0062] As Figure 6 shown, the upper end of the blade 32 is also provided with a limiting card slot 36, the hoop 39 is clamped into the limiting card slot 36, so that the blade 32 can be limited to move up and down by clamping the hoop 39 in the limiting card slot 36. At the same time, the embedded groove 31 can also limit the left and right rotation of the blade 32, so as to realize the complete fixation of the blade 32 in combination with the hoop 39, so that the blade 32 can be more stable when being installed on the installation platform 30 and moving with the installation platform 30.

[0063] Therefore, the installer only needs to rotate the hoop 39, and through the cooperation between the ring tooth part 38 and the card slot part 41, that is, the alignment or misalignment between the convex part 40 and the recess 37, the hoop 39 can be separated or put into the installation platform 30, so as to realize the dismounting and fixation of the blade 32, which is simple and fast.

[0064] The specific working process of the scheme is as follows:

[0065] As Figure 7 and 8 shown, when the cutter 9 moves downward to the set position, the outer side of the blade part 11 cooperates with the blocking part 8 to form a closed shearing space 100; during the downward shearing process of the cutter 9, the shearing space 100 gradually shrinks.

[0066] When there is hair in the drain, the intercepting platform 7 first intercepts the hair, and then the user only needs to press the pressing cover 2, so that the cutter 9 can move downward with the pressing cover 2, and then the blade part 11 of the cutter 9 cooperates with one side of the blocking part 8 to realize the cutting of the hair on the intercepting platform 7. After that, the user no longer exerts force, and the elastic element 19 can drive the pressing cover 2 to reset.

[0067] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
