[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0037] like Figure 1-Figure 5 As shown, the utility model provides a sink filter deodorizer, including a base 1 and a filter basket 2, the base 1 includes a horizontal portion 11 and a vertical portion 12 connected in sequence, the horizontal portion 11 can cover the drain outlet of the stainless steel basin, the vertical portion 12 is provided with an accommodating cavity for accommodating the filter basket 2, a sealing ring 13 is sleeved on the outer peripheral wall of the vertical portion 12, and a concave-convex structure 131 is provided on the outer peripheral wall of the sealing ring 13.

[0038] The horizontal portion 11 can tightly cover the drain ports of stainless steel basins of different diameters, so that the sink filter deodorizer can adapt to stainless steel basins of different models, thereby improving the versatility and applicability of the sink filter deodorizer.

[0039] The vertical portion 12 is used to accommodate the filter basket 2, and the sealing ring 13 mounted on the outer peripheral wall of the vertical section enhances the sealing between the base 1 and the drain of the stainless steel basin. At the same time, the concave-convex structure 131 on the outer peripheral wall of the sealing ring 13 can be adaptively fine-tuned according to drains of different diameters to ensure a close fit between the sealing ring 13 and the drain, thereby further improving the versatility and applicability of the sink filter deodorizer.

[0040] As an optional implementation, Figure 1 , 5 As shown, it also includes an anti-odor cover 3, which is matched with an inclined surface at the connection between the anti-odor cover 3 and the horizontal part 11 and the vertical part 12. A holding plate 31 is provided at the outer periphery of the anti-odor cover 3. The holding plate 31 is an arc-shaped plate structure and is inclined toward the horizontal part 11.

[0041] Furthermore, the outer side wall of the odor-proof cover 3 forms a first inclined surface 32 , and the connection between the horizontal portion 11 and the vertical portion 12 forms a second inclined surface 14 matched with the first inclined surface 32 .

[0042] The bottom surface of the odor-proof cover 3 is provided with anti-skid protrusions 33 to increase the stability of the odor-proof cover 3 when placed on other platforms and prevent it from sliding or falling.

[0043] When the odor-proof cover 3 is installed, the first inclined surface 32 and the second inclined surface 14 cooperate with each other, and the squeezing force between the two improves the sealing effect between the odor-proof cover 3 and the base 1, effectively preventing the escape of odors, mosquitoes, etc. in the sewer pipe. It can also make the odor-proof cover 3 slide smoothly during installation and removal, and the operation is convenient.

[0044] The gripping plate 31 is an arc-shaped plate structure, which conforms to the ergonomic principle, is comfortable to hold, and has a certain visual beauty.

[0045] As an optional implementation, friction protrusions 311 are provided on the wall surface of the holding plate 31 , and there are multiple friction protrusions 311 arranged according to a specific pattern.

[0046] Furthermore, the friction protrusions 311 are dot-shaped protrusions, which provide a good grip feel.

[0047] The function of the friction protrusion 311 is to provide sufficient friction force when the user's hand contacts the gripping plate 31 to prevent the hand from slipping.

[0048] As an optional implementation, Figure 1-Figure 3 As shown, the filter basket 2 includes a cup body 21 and a base 22. A first snap-fitting piece 211 is provided on the inner circumferential wall of the cup body 21. A first limiting groove 121 adapted to the first snap-fitting piece 211 is provided on the vertical portion 12. One side of the base 22 is rotatably connected to the cup body 21, and the other side is detachably connected to the cup body 21 through a hook structure.

[0049] Furthermore, there are multiple first locking members 211, which are sequentially spaced and arranged along the circumference of the cup body 21. The first limiting grooves 121 and the first locking members 211 are arranged one by one.

[0050] The cup body 21 is stably mounted on the vertical portion 12 by the first clamping member 211 and the first limiting groove 121. The specific structures of the first clamping member 211 and the first limiting groove 121 adopt the existing technology and will not be described in detail.

[0051] The detachable design of the cup body 21 and the base 22 ensures the stability of the filter basket 2 and facilitates the user to disassemble and clean it.

[0052] As an optional implementation, Figure 3 , 4 As shown, it also includes a driving structure, which includes a sleeve 4, a pressing rod 5 and a spring 6. A circumferentially closed first mounting portion 15 is provided on the inner side of the vertical portion 12 for mounting the sleeve 4, and a circumferentially closed second mounting portion 23 corresponding to the first mounting portion 15 is provided on the inner side of the cup body 21 for mounting the hook structure; the outer wall surface of the pressing rod 5 is connected to the inner wall surface of the sleeve 4 through the spring 6; a positioning groove is provided on the hook structure 7 for fixing the pressing rod 5; an elastic protrusion 72 is provided on the outer wall surface of the hook structure, a groove 212 matched with the elastic protrusion 72 is provided on the inner wall surface of the vertical portion 12, a hook body 71 is provided at the bottom of the hook structure, and a slot 221 matched with the hook body 71 is provided on the base 22.

[0053] Furthermore, the pressing portion of the pressing rod 5 is in sliding contact with the sleeve 4 .

[0054] The hook structure 7 has a third inclined surface 74 , and the positioning groove is formed on the third inclined surface 74 . When the hook structure 7 rotates, the pressing rod 5 will be guided and stably positioned in the positioning groove due to the effect of the third inclined surface 74 .

[0055] The filter basket 2 has a first state and a second state. In the first state, the elastic protrusion 72 is engaged in the groove 212 to provide a force for the hook body 71 to be fixed with the slot 221 so that the base 22 and the cup body 21 are tightly connected.

[0056] When the cup body 21 needs to be separated from the base 22, the pressing rod 5 is manually pressed. After the pressing rod 5 is subjected to pressure, the spring 6 is compressed to move downward and squeeze the elastic protrusion 72, driving the hook body 71 to be subjected to an outward force, so that it rotates and disengages from the slot 221, so that the cup body 21 is separated from the base 22, so that the filter basket 2 is switched from the first state to the second state, which is convenient for users to disassemble and clean, and the hands do not need to directly contact the base 22, and will not get their hands dirty.

[0057] Since the first mounting portion 15 and the second mounting portion 23 are both circumferentially closed structures and the vertical gap between the first mounting portion 15 and the second mounting portion 23 is small, it can effectively prevent residues from entering the first mounting portion 15 and the second mounting portion 23 and interfering with the pressing rod 5 and the hook structure.

[0058] The first mounting portion 15 is protruded inwardly from the horizontal portion 11 , the shape of the odor-proof cover 3 is adapted to the horizontal portion 11 and the first mounting portion 15 , and the first mounting portion 15 and the odor-proof cover 3 are connected at an inclined surface.

[0059] As an optional implementation, a second snap-fitting member 41 is disposed at the bottom of the sleeve 4 . The second snap-fitting members 41 are symmetrically disposed and are snap-fitted with the third snap-fitting members 151 of the first mounting portion 15 , respectively.

[0060] The sleeve 4 is stably mounted on the first mounting portion 15 by the engagement of the second locking member 41 and the third locking member 151. The specific structures of the second locking member 41 and the rotating groove adopt the existing technology and will not be described in detail here.

[0061] As an optional implementation, a rotation groove is provided on the second mounting portion 23, and an anti-drop rod 73 adapted to the rotation groove is provided on the hook structure.

[0062] Furthermore, a rotation groove is provided on the top of the second mounting portion 23, and the upper end of the rotation groove is open. An anti-dropout rod 73 adapted to the rotation groove is provided on the top of the hook structure, and the anti-dropout rod 73 is installed in the rotation groove, and the two form a rotational fit, so that the hook structure can rotate within a certain range relative to the second mounting portion 23, that is, when the pressing rod 5 is subjected to pressure, the elastic protrusion 72 is squeezed, and the hook structure is driven to rotate within a certain range relative to the second mounting portion 23, so that the hook body 71 rotates and disengages from the slot 221 on the base 22, so as to realize the switching of the filter basket 2 from the first state to the second state.

[0063] As an optional implementation, a lower limit member 51 is provided on the pressing rod 5 located inside the sleeve 4 for limiting the downward movement of the pressing rod 5 ; an anti-slip upper limit member 52 is provided on the pressing rod 5 located outside the sleeve 4 for limiting the upward movement of the pressing rod 5 .

[0064] The function of the lower limit member 51 is to limit the maximum distance that the pressing rod 5 moves downward. The function of the anti-slip upper limit member 52 is to limit the maximum distance that the pressing rod 5 moves upward.

[0065] When the filter basket 2 is in the first state, the elastic protrusion 72 is clamped in the groove 212, providing a force for the hook body 71 to be clamped and fixed with the clamping groove 221, and the base 22 and the cup body 21 are in a tightly connected state. The anti-slip upper limit positioning member 52 will abut against the bottom surface of the bottom plate of the sleeve 4, so that the pressing rod 5 can maintain a stable state when not affected by external force, thereby ensuring the stability and reliability of the connection between the base 22 and the cup body 21.

[0066] When the cup body 21 needs to be separated from the base 22, the pressing rod 5 is manually pressed. After the pressing rod 5 is subjected to pressure, the spring 6 is compressed to move downward and squeeze the elastic protrusion 72, driving the hook body 71 to be subjected to an outward force, so that it rotates and disengages from the slot 221, so that the cup body 21 is separated from the base 22, so that the filter basket 2 is switched from the first state to the second state, which is convenient for the user to disassemble and clean, and the hands do not need to directly contact the base 22, so as not to get their hands dirty. At this time, the lower limiter 51 abuts against the top surface of the bottom plate of the sleeve 4, so that the pressing rod 5 can maintain a stable state after reaching the maximum downward movement distance.

[0067] As an optional embodiment, a handle 8 is further included. The handle 8 is arranged oppositely and vertically on the sleeve 4 and is bent and extended downward.

[0068] The handle 8 is bent and extended downward, and the design conforms to the principle of ergonomics. The user only needs to naturally hold the handle 8 to easily and conveniently lift or move the filter basket 2 without getting his hands dirty.

[0069] The handle 8 and the sleeve 4 are combined to form a shape similar to a wooden man, making the sink filter deodorizer more interesting in appearance.
