DETAILED DESCRIPTION

[0021] 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.

[0022] Example: Reference Figure 1-2 A length-adjustable cotton-absorbing flute tube is shown, comprising a flute tube body 1, a plurality of first air inlet holes 2 are evenly and evenly spaced at the bottom of the flute tube body 1, an air outlet pipe 3 is arranged at the upper end of the flute tube body 1, both ends of the flute tube body 1 are open, and an adaptable extension tube 5 is slidably sleeved on both ends of the flute tube body 1, and one end of the extension tube 5 close to the air outlet pipe 3 is open, and the other end is sealed, a plurality of second air inlet holes 6 are evenly spaced at the lower end of the extension tube 5, an elastic sealing pad 8 is arranged on the inner wall of the extension tube 5, and the inner wall of the elastic sealing pad 8 is in sliding contact with the outer wall of the flute tube body 1;

[0023] When the extension tube 5 is completely sleeved on the flute body 1 , the plurality of second air inlet holes 6 on the extension tube 5 completely overlap with the corresponding first air inlet holes 2 on the flute body 1 .

[0024] According to the required coverage range, the extension tube 5 can be pulled to move outward relative to the flute tube body 1 to extend the length of the cotton suction flute tube, increase the number of air holes, and thus increase the coverage range of the cotton suction flute tube. The contact surface between the extension tube 5 and the flute tube body 1 is sealed by the elastic sealing pad 8 to avoid air leakage at the contact connection.

[0025] It should be noted that, first, the first air inlet hole 2 and the second air inlet hole 6 are of the same size; second, the multiple second air inlet holes 6 on the extension tube 5 can completely overlap with the corresponding first air inlet holes 2, and the multiple first air inlet holes 2 and the multiple second air inlet holes 6 are arranged at equal intervals. After each adjustment, it is necessary to ensure that the second air inlet holes 6 on the extension tube 5 mounted on the outer wall of the flute body 1 overlap with the corresponding first air inlet holes 2 one by one. The purpose is to prevent the extension tube 5 from blocking the air inlet port of the first air inlet hole 2 after the extension adjustment, so that its suction area is reduced, which is easy to affect the subsequent suction effect of broken ends or flying flowers.

[0026] As a preferred implementation in this embodiment, Figure 1 and Figure 2 As shown, the two extension tubes 5 are both threadedly connected with positioning screws 7, and the flute body 1 is provided with a plurality of positioning blind holes 4 at equal intervals, and each positioning blind hole 4 is provided in one-to-one correspondence with the plurality of first air inlet holes 2.

[0027] In order to ensure the stability of the extension tube 5 and the flute tube body 1, a first positioning screw 7 is provided, and the positioning screw 7 is plugged into the positioning blind hole 4 to achieve the fixation of the extension tube 5 and the flute tube body 1. At the same time, since each positioning blind hole 4 is arranged in a one-to-one correspondence with a plurality of first air inlet holes 2, after fixation, a plurality of second air inlet holes 6 sleeved on the flute tube body 1 overlap with the corresponding first air inlet holes 2 one by one, preventing the extension tube 5 from blocking the first air inlet holes 2 on the flute tube body 1, ensuring that the size of the suction air hole is not changed. Subsequently, the suction flow rate of the air inlet hole can be kept unchanged according to the power of the suction equipment, so as to ensure the subsequent suction effect of broken ends or flying flowers in each area.

[0028] As a preferred implementation in this embodiment, Figure 3 As shown, an automatic reminder unit is also included. The extension tube 5 moves on the flute body 1 and each time the first air inlet hole 2 and the second air inlet hole 6 overlap, the automatic reminder unit will automatically emit a sound to remind the person.

[0029] When the extension tube 5 is pulled to move on the flute tube body 1, a sound will be automatically emitted each time the second air inlet hole 6 on the extension tube 5 sleeved on the flute tube body 1 overlaps with the first air inlet hole 2 one by one, indicating that the flute tube body 1 is extended by an additional air hole. The number of additional air holes can be understood by the number of times the sound is emitted, and the sound can be used as a reminder, so that the number of additional air holes can be understood even in an environment with poor visibility.

[0030] As a preferred implementation in this embodiment, Figure 3 and Figure 4As shown, the automatic reminder unit includes a shell 9 communicated with the inner cavity of the extension tube 5, the inner cavity of the shell 9 is provided with a roller 13 which is rotatable by a rotating shaft 10, and the lower end of the roller 13 is in contact with the outer wall of the flute tube body 1, a baffle 11 is fixed on the rotating shaft 10, and a vibration plate 12 is provided on the right side of the baffle 11, and the lower end of the vibration plate 12 is located below the upper end of the baffle 11, and the upper end of the vibration plate 12 is fixedly connected to the top of the inner cavity of the shell 9, a sound hole is opened on the outer wall of the shell 9, and a filter screen 14 is provided in the inner cavity of the sound hole, and the distance traveled by the roller 13 each time it rolls one circle is equal to the spacing distance between two adjacent first air inlet holes 2.

[0031] When the extension tube 5 moves outward, its roller 13 will roll due to the friction between it and the outer wall of the flute tube body 1, and the baffle 11 on the rotating shaft 10 will rotate and contact the lower end of the vibration plate 12, driving the vibration plate 12 to bend in the direction of the movement of the extension tube 5. After the baffle 11 contacts and separates from the lower end of the vibration plate 12, the lower end of the vibration plate 12 swings back and forth quickly to make a sound. When the sound is heard, it means that the flute tube body 1 has been extended to add an air hole (and the second air inlet hole 6 corresponds to the corresponding first air inlet hole 2 one by one). Continue to move the extension tube 5. Hearing several sounds means that several air holes have been added. Even in an environment with poor visibility, the number of added air holes can be understood, and the extended length of the flute tube body 1 can be understood, so that the length of the flute tube cup body 1 can be adjusted conveniently.

[0032] It should be noted that, firstly, the filter 14 is provided to prevent dust accumulation inside the housing 9 and avoid reducing the sound of the vibration plate 12; secondly, during the whole process, the baffle 11 does not bend or deform.

[0033] As a preferred implementation in this embodiment, Figure 4 As shown, the filter 14 is tilted outward, and a material guide slope 15 is tilted in the inner cavity of the sound outlet and near the bottom of the filter 14 . The filter 14 is woven with metal wires, and the vibration frequency of the metal wires is consistent with the vibration frequency of the vibration plate 12 .

[0034] When the vibration plate 12 vibrates by swinging back and forth, the filter 14 will vibrate because its vibration frequency is consistent with that of the filter 14. The dust attached to the filter 14 will be shaken off by the vibration of the filter 14 and fall onto the guide slope 15, and finally slide down along the guide slope, so as to avoid clogging of the filter 14 and affecting the propagation of sound.

[0035] It should be noted that the outer wall of the filter 14 is fixedly connected to the inner wall of the sound outlet through a flexible member 16. The provision of the flexible member 16 is beneficial to improving the resonance strength of the filter 14 and facilitating the shaking off of dust thereon. The flexible member 16 is provided as an annular connector made of elastic material, which is elastic and can seal the gap between the outer wall of the filter 14 and the sound outlet.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
