Technical Field

[0001] The invention belongs to the technical field of children's toys, and in particular relates to a lung capacity training device for children. Background Art

[0002] Vital capacity refers to the amount of air that can be exhaled after maximum inhalation. It includes tidal volume, inspiratory reserve volume and expiratory reserve volume. Generally speaking, the stronger the body, the greater its value. Studies have shown that it is highly correlated with maximum oxygen uptake. It is often used as an indicator to evaluate human fitness, so simple exercises for vital capacity can be performed in childhood.

[0003] The lung capacity training devices for children currently on the market are rather dull and difficult to arouse children's interest, and are prone to hygiene problems after repeated use. Summary of the invention

[0004] The purpose of the present invention is to provide a lung capacity training device for children, which solves the existing problems.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] Furthermore, the blowing nozzle mounting mechanism includes a blowing nozzle and a mounting plate, the front end of the blowing nozzle is fixedly connected with an insert block, the surface of the insert block is provided with a slot, the rear end of the mounting plate is provided with a slot, an elastic spring is arranged inside the slot, a groove is arranged on the inner wall of the slot, a telescopic spring is arranged inside the groove, an arc block is slidably connected inside the groove through the telescopic spring, the arc block is fixedly connected with a pull rod at one end close to the telescopic spring, and the pull rod passes through the mounting plate and is slidably connected.

[0008] Furthermore, the air hole is connected to the rising tube, and the material of the rising tube is transparent plastic material. The air pressure in the rising tube can finally be discharged through the air hole. The rising tube made of transparent plastic material allows children to observe the situation of the rising ball inside.

[0009] Furthermore, the inner diameter of the limiting ring is smaller than the outer diameter of the rising ball, and the smaller inner diameter of the limiting ring prevents the rising ball from falling below the limiting ring.

[0010] Furthermore, the insert block is in conflict with the elastic spring in the initial state, and the elastic spring is in a tightened state in the initial state, and the elastic spring will drive the insert block to leave the slot when it rebounds.

[0011] Furthermore, the end of the arc block away from the telescopic spring is initially in the slot, the arc surface of the arc block faces the opening direction of the slot, the arc block is stuck in the slot so that the plug-in block cannot leave the slot, and the arc surface of the arc block will move into the groove when squeezed.

[0012] The present invention has the following beneficial effects:

[0013] 1. When the child's lung capacity needs to be trained, the present invention can blow air into the air tube through the air nozzle. The air pressure generated at this time will enter the riser tube from the air tube to drive the riser ball to rise, and the child can observe the rise of the riser ball through the transparent riser tube, which can better arouse the child's interest in combination with the toy shell and the toy body.

[0014] 2. The present invention is provided with a blowing nozzle installation mechanism, so that when the blowing nozzle needs to be cleaned after multiple uses, the pull rods at the upper and lower ends of the installation plate can be pulled, and the blowing nozzle will automatically separate from the blowing pipe for cleaning. When installing again, the front end plug block of the blowing nozzle is aligned with the rear end slot of the installation plate and inserted. At this time, the arc block will automatically snap into the slot to complete the installation of the blowing nozzle. The installation and disassembly are simple, not easy to fall off, and convenient for daily cleaning work.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The blowing nozzle mounting mechanism 8 includes a blowing nozzle 81 and a mounting plate 83, the front end of the blowing nozzle 81 is fixedly connected with an insert block 82, the surface of the insert block 82 is provided with a slot 84, the rear end of the mounting plate 83 is provided with a slot 85, the interior of the slot 85 is provided with an elastic spring 86, the inner wall of the slot 85 is provided with a groove 87, the interior of the groove 87 is provided with a telescopic spring 88, the interior of the groove 87 is slidably connected with an arc block 89 through the telescopic spring 88, the end of the arc block 89 close to the telescopic spring 88 is fixedly connected with a pull rod 810, and the pull rod 810 passes through and is slidably connected to the mounting plate 83.

[0024] The air hole 4 is connected with the rising tube 2, and the material of the rising tube 2 is transparent plastic material. The air pressure in the rising tube 2 can finally be discharged through the air hole 4. The rising tube 2 made of transparent plastic material allows children to observe the situation of the internal rising ball 6.

[0025] The inner diameter of the limiting ring 5 is smaller than the outer diameter of the rising ball 6. The smaller inner diameter of the limiting ring 5 prevents the rising ball 6 from falling below the limiting ring 5. An adhesive layer is provided on the upper surface of the limiting ring 5, and a surface layer capable of bonding with the adhesive layer is provided on the outer surface of the rising ball 6. The adhesive layer is an adhesive resin layer, which is a transparent single-layer adhesive resin layer containing an acrylic adhesive resin composition. The adhesive resin composition contains (A) acrylic polymer, (B) urethane acrylate, and (C) thermal polymerization initiator, and may also contain (D) acrylic monomer at will. The adhesive resin layer (11) is adhesive on both sides (11a) and (11b) at room temperature. The surface layer is an adhesive resin layer, and its bonding strength is one tenth of that of the adhesive layer. The user can increase the exercise intensity by separating the adhesive layer and the surface layer during the blowing process, and the strength can be increased by adjusting the bonding strength.

[0026] In the initial state, the insert block 82 contacts the elastic spring 86 , and the elastic spring 86 is in a taut state in the initial state. When the elastic spring 86 rebounds, it drives the insert block 82 to leave the slot 85 .

[0027] The end of the arc block 89 away from the telescopic spring 88 is initially in the slot 84, and the arc surface of the arc block 89 faces the opening direction of the slot 85. The arc block 89 is stuck in the slot 84 so that the insertion block 82 cannot leave the slot 85. When the arc surface of the arc block 89 is squeezed, it will move into the groove 87.

[0028] A specific application of this embodiment is: when in use, the child blows air into the blowing tube 7 through the blowing nozzle 81. The air pressure generated at this time will enter the rising tube 2 through the blowing tube 7 to push the rising ball 6 to rise. The air pressure is finally discharged from the air hole 4, and the child can observe the rise of the rising ball 6 through the transparent rising tube 2. Combined with the toy shell 1 and the toy body 3, it can better arouse the interest of the child and play with the effect of exercising lung capacity. When the blowing nozzle 81 needs to be cleaned after long-term use, the pull rods 810 at the upper and lower ends of the mounting plate 83 are pulled to drive the arc block 89 to leave the slot 84 and retract into the groove 87. At this time, the elastic spring 86 will rebound to drive the plug block 82 to pop out of the slot 85, The blowing nozzle 81 is separated from the blowing tube 7 for cleaning, and then the telescopic spring 88 rebounds to drive the arc block 89 and the pull rod 810 to be restored. When installing again, the front end plug block 82 of the blowing nozzle 81 is aligned with the rear end slot 85 of the mounting plate 83 and inserted, the elastic spring 86 is gradually tightened, and the arc surface of the arc block 89 is initially squeezed by the rear end of the plug block 82 and retracted into the groove 87. The telescopic spring 88 is tightened. When the groove 87 is fitted with the card slot 84, the telescopic spring 88 will rebound and drive the arc block 89 to be stuck in the card slot 84, so that the plug block 82 cannot leave the slot 85, thereby firmly installing the blowing nozzle 81 on the blowing tube 7. The installation and disassembly are simple and not easy to fall off, which is convenient for daily cleaning work.
