The second rotation axis X2 is parallel to the first rotation axis X1 about which the comb member 12 is wound, and the perpendicular distance between the first rotation axis X1 and the second rotation axis X2 is not equal to zero.

The shaving frame 29 surrounds the comb teeth 26 and can rotate with the comb teeth 26 between a combing position and a hair-catching position. When the comb teeth 26 are in the combing position, the shaving frame 29 is close to the support frame 25. When the comb teeth 26 are rotated from the combing position to the hair sucking position, the shaving frame 29 slides from a position close to the support frame 25 toward the tips of the comb teeth, in the process, the hairs hanging on the comb teeth are pushed toward the tips of the comb teeth close to the damper 32, so that the hairs are subjected to stronger suction force and are sucked away.

For any point A on the shaving frame 29, when the shaving frame 29 is located at the combing position, the point A is located at the position A1, when the shaving frame 29 is located at the hair sucking position, the point A is located at the position A2, and the perpendicular bisector of the connecting line of the points A1 and A2 intersects with the second rotating shaft X2.

The combing position is a position where the comb teeth extend from the front end portion in a direction away from the hollow handle 23. The hair sucking position refers to a position where the comb teeth point to the hollow handle 23 from the front end portion, the tooth tips of the comb teeth are located in front of the air door 32 and can point to the inside of the air door 32, and the tooth tips can also point to the lower side of the air door 32, so long as the hair scraping assembly 13 can push the hair on the comb teeth to the tip ends of the comb teeth, the hair can be sucked into the air door 32, and then the comb teeth are located at the hair sucking position.

As shown in FIG. 4, the inner wall of the front blade 57 has a front blade inside upper edge 59 adjacent the support bracket 25, the inner wall of the rear blade 58 has a rear blade inside upper edge 60 adjacent the support bracket 25, and the distance between the front blade inside upper edge 59 and the rear blade inside upper edge 60 forms the top clearance of the squeegee frame 29. The inner wall of the front blade 57 has a front blade inner side lower edge 61 near the tip of the tooth, the inner wall of the rear blade 58 has a rear blade inner side lower edge 62 near the tip of the tooth, and the distance between the front blade inner side lower edge 61 and the rear blade inner side lower edge 62 constitutes the bottom gap of the squeegee frame 29. The top gap of the shaving frame 29 can be equal to the bottom gap of the shaving frame 29, and can also be larger than the bottom gap of the shaving frame 29. When the clearance at the top of the shaving frame 29 is equal to the clearance at the bottom of the shaving frame 29, the fitting clearance of the shaving frame 29 with the upstream and downstream surfaces is slightly enlarged, otherwise, the friction between the comb teeth and the shaving frame 29 may be large during the rotation from the combing position to the hair sucking position, resulting in the combing member 12 being stuck and unable to rotate. When the top gap of the shaving frame 29 is larger than the bottom gap of the shaving frame 29, the matching gap between the bottom of the shaving frame 29 and the upstream surface and the downstream surface can be very small, in the illustrated embodiment, the matching gap is 0.2mm, and can be designed to be zero or even smaller than zero, because the plastic shaving frame 29 can be adopted, the shaving frame 29 is in close contact with the comb teeth by using the elasticity of the plastic piece, the hairs hung on the comb teeth are more easily pushed to move towards the tooth tips along the extending direction of the comb teeth 26, the hairs are moved to the tooth tips close to the air door 32 from the position far away from the weaker suction force of the air door 32, and the stronger suction force is borne, so the hairs are more easily sucked into the air door 32 and then enter the dust collector.

The trajectories of the excitation element 24 and the transmission rod 37 in the first embodiment shown in fig. 1, 2, 3, 4, 5, 6 and 7 are all planar.

< example two >

In the second embodiment, the same reference numerals are used for the same structures as in the first embodiment.

FIG. 8 is a top plan view of a suction cleaner nozzle in accordance with a second embodiment of the present invention; FIG. 9 is a cross-sectional view B-B of the suction cleaner nozzle of FIG. 8 with the comb member extended outwardly in a combing position; fig. 10 is a cross-sectional view B-B of the vacuum cleaner nozzle of fig. 8, wherein the comb member is directed towards the handle, in a bristle sucking position.

As shown in fig. 8, 9 and 10, the bottom surface 63 of the excitation member 24 and the bottom surface 64 of the transmission lever 37 are both curved, and the excitation member 24 and the transmission lever 37 advance and retreat along an arc-shaped trajectory. When the comb member 12 is in the combing position, the tooth tips of the comb teeth are at a greater vertical distance H1 from the hollow grip 23, and the palm of the hand holding the hollow grip 23 is less likely to touch the body of the pet during combing.

< modification example >

In this modification, the same reference numerals are used for the same components as in the first embodiment.

In the first embodiment, a gill is adopted, the comb teeth 26 of the gill are gills, the gills are long, the gills can penetrate into the pet hair layer to fully massage the pet body and can straighten the pet hair, but the comb teeth of the gill are smooth, and the effect of removing loose hair is not good enough. As shown in fig. 11, as a modification, a plate-type comb 66 may be used, which includes comb teeth and a base 67, one end of the base 67 is fixed to the support 65, and one end of the base away from the support 65 is provided with a plurality of comb teeth, which extend in a direction away from the base 67 and away from the support 65, and the height of the tip of each comb tooth from the base is not more than 5 mm. When the comb member is in the combing position, the upstream surface of the different teeth upstream of the suction air stream lies in a first plane P3, the downstream surface of the different teeth downstream of the suction air stream lies in a second plane P4, P3 and P4 are parallel to each other, the plane of base 67 between two adjacent teeth constitutes a tooth root surface 68, tooth root surface 68 is perpendicular to the planes P3 and P4, respectively, and to the direction in which the teeth extend outwardly from the base. In the structure, because the height of the comb teeth is not more than 5mm, the comb teeth can only move on the surface of the pet hair layer and can only be in full contact with the scattered hair which is floated on the surface of the hair layer, and the healthy hair planted in the hair follicle of the pet cannot generate great pulling force, therefore, in the flat plate type comb, the roughness of the surface of the comb teeth can be made larger, so that the scattered hair can be more easily combed away from the pet hair layer.

In the case of the flat comb, when the combing member 12 is rotated to the hair sucking position, the lower edge of the shaving frame 29 passes over the tooth root surface 68 from a position close to the supporting frame 25, closes a part of the gap between the tooth root surface 68 and the tooth tip, the air passing area between the base 67 and the damper 32 is reduced, the air flow velocity passing the tooth tip is increased, and the hair caught on the comb teeth is pushed to the tooth tip by the shaving frame and then is subjected to a stronger suction force, and thus is sucked more easily.
