The carding opening 62 and the air leakage window 53 enter the damper 60, and then enter the air duct 50 through the air inlet duct to flow to the dust collecting chamber of the vacuum cleaner. At this time, it is possible to start grooming the pet with the vacuum cleaner nozzle 10.

After a certain amount of hair is accumulated on the comb teeth 31, the user can push the push button 20 forward with the thumb, and the remaining four fingers grip the outer wall of the hollow handle 50. The push button 20 drives the link 24 to advance, the link 24 compresses the spring 23 during the advancement, and the rack 55 on the link 24 pushes the driven tooth 57 on the gear 28 to rotate in the B direction (see Fig. 5), so that the gear 28 It also rotates in the B direction, and at the same time drives the transmission ring 29 to rotate in the B direction. The transmission ring 29 then drives the carding member 12 to the damper 60 from the carding state in the B direction (see FIG. 5), and stops at the front of the damper 60 to enter the storage state. The comb teeth 31 are directed to the inside of the damper 60 (see Fig. 6). At this time, the carding opening 62 and the air leakage window 53 respectively transmit airflow from the upper and lower directions of the comb teeth 31 to the damper 60 (see FIG. 6), and the direction of the suction airflow passing through the comb teeth 31 is substantially the same as the extending direction of the comb teeth 31, and is sucked. As long as the airflow can overcome the friction between the hair and the smooth comb 31, the hair can be separated from the comb 31 into the damper 60, and then flow to the dust collector of the vacuum cleaner.

After the thumb releases the push button 20, the spring 23 is reset from the deep compression state, pushing the link 24 backward, and the rack 55 on the link 24 drives the driven tooth 57 to rotate in the opposite direction of B (see FIG. 5), and then through the transmission. The ring 29 drives the carding member 12 to swing and reset, so that the comb teeth 31 return to the carding state.

After the carding is finished, the thumb pushes the push button 20 forward, so that the carding member 12 is turned to the damper to enter the storage state, and at this time, the lock push button 21 is pushed in the A direction (see FIG. 4), and when the lock block 52 on the lock push button 21 falls When the locking groove 56 is inserted into the connecting rod 24 (see Fig. 8), the connecting rod 24 is fixed by the locking push button 21, and at this time, the push button 20 is released, and the comb member 12 is also kept in the stowed state, and the comb teeth 31 are pointed. The damper 60 can effectively avoid accidental impact.

When it is necessary to comb again, as long as the locking push button 21 is pushed in the opposite direction of A (see Fig. 4), the locking block 52 on the locking push button 21 is separated from the locking groove 56 of the connecting rod 24 (see Fig. 7).

Action description:

In the second embodiment, the vacuum cleaner nozzle 100 is first connected to the air duct connecting portion of the vacuum cleaner, the comb teeth 131 are outwardly extended from the carding opening 162, and then the vacuum cleaner power is turned on to allow the suction airflow to pass through the combing opening 162. The air leakage window 153 enters the damper 160 and enters the air passage 150 through the air intake duct, thereby flowing to the dust collecting chamber of the vacuum cleaner. At this time, the vacuum cleaner nozzle 100 can be used to clean the carpet and wait for the cleaning surface.

After a certain amount of hair is accumulated on the comb teeth 131, the knob 120 is rotated in the B direction (see FIG. 13), and the knob 120 drives the driving ring 132 to rotate by the driving rib 164 and the driven groove 163, and the driving ring 132 drives the base of the combing member 112. The seat 130 rotates, and the base 130 drives the comb teeth 131 Pointing inside the damper 160, that is, downstream of the suction airflow (see Figure 14). At this time, the carding opening 162 and the air leakage window 153 respectively transmit airflow from the upper and lower directions of the comb teeth 131 to the damper 160 (see FIG. 14), and the direction of the suction airflow passing through the comb teeth 131 is substantially the same as the extending direction of the comb teeth 131. As long as the suction airflow can overcome the friction between the hair and the smooth comb 131, the hair can be released from the comb tooth 131 into the damper 160, and then flow to the dust collector of the vacuum cleaner.

While the comb teeth 131 are turned to the damper 160, the base 130 simultaneously drives the driven ring 129 to rotate, the driven ring 129 drives the gear 128 to rotate, and the gear teeth 157 on the gear 128 drive the rack 155 on the connecting rod 124 to move forward (see Figure 11), the link 124 will compress the spring 123 while moving forward.

After the knob 120 is released, the spring 123 is reset from the compressed state, and the link 124 is pushed back.

The locking push button 121 can be located in two positions, one being the locked position and the other being the unlocked position. As shown in Figures 9, 11, and 12, icons can be separately set to correspond to the two positions to indicate the locked and unlocked states.

In the second embodiment, the triggering device of the driving member 113 is away from the air duct 150 (operating handle) and is close to the combing member 112, so that the user can operate with both hands, that is, one hand holds the operating handle, and the other hand drives the carding member 113. Further, the connecting rod 124 spans the damper 160, interlocks with the combing member 113, and is provided with a locking block 152 in the stroke of the connecting rod 124, which can be embedded in the connecting rod 124 to restrict the movement of the connecting rod 124, thereby achieving locking.

Further, in the vacuum cleaner nozzle of the second embodiment, the carding member is also replaceable.

Of course, the driving member in the second embodiment can also be simplified, the parts such as the connecting rod/rack/gear are removed, and the reset mechanism, such as the return spring, is retained, so that the combing member can be positioned while extending outward from the carding opening. The driving combing member is realized only by the knob, and the hook is arranged on the lower cover portion or other frame parts, and is connected with the corresponding hinge or the like on the knob, so that the combing member can be locked when it is in the storage state to prevent accidental damage.

As described above, the vacuum cleaner nozzle of the second embodiment needs the user's two-hand operation. In order to balance both the left-hand and the right-hand operation habits, the simplified mechanism can be used, and the knobs on both sides of the carding member can be designed as active components to make them Both can trigger the rotation of the comb member.

The role and effect of the embodiment

According to the vacuum cleaner nozzles described in the first and second embodiments, since the locking push button can lock the comb member to the storage position, the comb teeth are located inside the body and are directed to the damper, so the user can press the push button by pressing the push button when needed. The teeth are stored so that the comb teeth are no longer exposed, so that the effect of effectively reducing the accidental damage of the comb teeth can be achieved.
