Description

Technical Field

[0001] The utility model relates to the field of daily life, in particular to a sound tube structure. Background Art

[0002] Existing whistle structures are usually made of metal or plastic, and are blown by the mouth to produce sound. They are mostly used in some cultural and entertainment activities in daily life. Patent No. ZL201521037084.2 discloses an improved whistle structure, which improves the bead structure inside the existing whistle and improves the use effect of the whistle. However, the whistle structure is still a mouth-blown structure, which requires people to blow air to make a sound. There has been no significant improvement in its structure, and it lacks fun. It is necessary to improve it. Summary of the Invention

[0003] The purpose of this utility model is to solve the above problems and provide a sound tube structure with simple structure and convenient use.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A sounding tube structure includes a sounding whistle body, a sleeve, a counterweight, and a plugging cover. The sleeve is in the shape of a cylindrical tube with one end sealed, and the open end of the sleeve is detachably connected to the plugging cover. The counterweight and the sounding whistle body are both arranged in the sleeve, and the counterweight is fixedly sleeved on the outside of the sounding whistle body. The outer diameter of the counterweight is adapted to the inner diameter of the cross section of the sleeve. The counterweight and the sounding whistle body can slide in the sleeve along the axis of the sleeve, so that air flows through the sounding whistle body during the sliding process and the sounding whistle body emits sound.

[0006] Furthermore, the length direction of the sound whistle body is consistent with the axial direction of the sleeve member, and the head end port and the tail end port of the sound whistle body are respectively arranged at both ends of the length direction of the sound whistle body.

[0007] Furthermore, the counterweight is arranged in a circular ring shape, and the sound whistle body is embedded in the inner side of the counterweight.

[0008] Furthermore, the blocking cover is nested on the outside of the open end of the sleeve, and a flow hole for transmitting sound and circulating air is provided on the end surface of the blocking cover.

[0009] Furthermore, the sleeve, plug cover, and sound whistle body are all plastic parts, and the counterweight is a metal part.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are:

[0011] When the utility model is used, it is only necessary to swing the sleeve member back and forth so that the counterweight block and the sound whistle body in the sleeve member slide back and forth along the axial direction of the sleeve member. During the sliding process of the counterweight block and the sound whistle body, they squeeze the air inside the sleeve member, so that the air forms an airflow that passes through the sound whistle body and causes the sound whistle body to vibrate, and finally the sound whistle body emits a sound. The overall structure of the utility model is greatly improved, which is completely different from the whistle structure in the prior art. The entire sound-emitting process only requires people to hold the sleeve member and swing it, and people do not need to blow air, which increases the interest and fun of playing with the whistle, thereby effectively improving the use effect of the utility model.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts, any modifications, equivalent replacements, improvements, etc., shall be included in the scope of protection of the present invention.

[0019] like Figure 1 、 Figure 2 and Figure 3As shown, this embodiment discloses a sound tube structure, including a sound whistle body 3, a sleeve member 1, a counterweight 4, and a plug cover 2. The sleeve member 1, the plug cover 2, and the sound whistle body 3 are all plastic parts, and the counterweight 4 is a metal part; the sleeve member 1 is a cylindrical tube with one end sealed, and the open end of the sleeve member 1 is nested with the plug cover 2. The end surface of the plug cover 2 is provided with a flow hole 201 for transmitting sound and air circulation. There are two flow holes 201, and the two flow holes 201 are both semicircular and symmetrically arranged. The flow holes 201 connect the outside with the inside of the sleeve member 1; the counterweight 4 and the sound whistle body 3 are all arranged in the sleeve 1, the length direction of the sound whistle body 3 is consistent with the axial direction of the sleeve member 1, and the head end port and the tail end port of the sound whistle body 3 are respectively arranged at both ends of the length direction of the sound whistle body 3, and the counterweight block 4 is arranged in an annular column shape and fixedly nested on the outside of the sound whistle body 3. The outer diameter of the counterweight block 4 is adapted to the inner diameter of the cross-section of the sleeve member 1 so that a certain airtightness is maintained between the two during the relative sliding process. The counterweight block 4 together with the sound whistle body 3 can slide in the sleeve member 1 along the axial direction of the sleeve member 1, so that the airflow passes through the air flow channel 301 inside the sound whistle body 3 during the sliding process and allows the sound whistle body 3 to emit a sound.

[0020] like Figure 4 As shown, when the sleeve is in an upright position, under the action of gravity, the counterweight and the sound whistle will slide toward the sealed end of the sleeve, which will squeeze the air in the cavity at the bottom of the counterweight, causing the air in the cavity at the bottom of the counterweight to transfer to the top of the counterweight through the air flow channel inside the sound whistle. When the air flow passes through the sound whistle, the sound whistle emits a sound.

[0021] like Figure 5 As shown, when the sleeve is in an inverted state, under the action of gravity, the counterweight and the sound whistle will slide toward the blocking cover, and the cavity above the counterweight will gradually increase and enter a negative pressure state. Under the action of negative pressure, the air below the counterweight will be sucked in, so that the air below the counterweight enters the cavity above the counterweight through the air flow channel inside the sound whistle. When the airflow passes through the sound whistle, the sound whistle makes a sound.

[0022] exist Figure 4 、 Figure 5 In the figure, the air flow channel in the sound whistle body is a simple schematic structure drawn for the convenience of understanding, and the structures such as the vibrating plate in the air flow channel are not drawn; the sound whistle body is a common sound generator structure on the market, which can make sounds when air is taken in in both directions. For example, the common "screaming chicken" toys on the market or other hand-squeezed rubber sound toys all use this sound generator structure.

[0023] When the utility model is used, it is only necessary to swing the sleeve member back and forth so that the counterweight block and the sound whistle body in the sleeve member slide back and forth along the axial direction of the sleeve member. During the sliding process of the counterweight block and the sound whistle body, they squeeze the air inside the sleeve member, so that the air forms an airflow that passes through the sound whistle body and causes the sound whistle body to vibrate, and finally the sound whistle body emits a sound. The overall structure of the utility model is greatly improved, which is completely different from the whistle structure in the prior art. The entire sound-emitting process only requires people to hold the sleeve member and swing it, and people do not need to blow air, which increases the interest and fun of playing with the whistle, thereby effectively improving the use effect of the utility model.
