[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments 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 are within the scope of protection of the present invention.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or location relationships based on the positions or location relationships shown in the accompanying drawings, or the positions or location relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0031] In the present invention, unless otherwise expressly specified or limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being above, above, and above the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] like Figure 1 and Figure 2 As shown, it includes a ventilating tube 1, the mouth end of which is integrally formed with a fixed wing 2, the fixed wing 2 having a wing 21 as a fixed section and flanges 22 on both sides that can be telescopically adjusted. Two pairs of wing wheels 23 are elastically connected near the upper end and near the lower end of the two sides of the flange 22, a head strap 24 is sleeved on the wing wheel 23 near the upper end, and a neck strap 25 is sleeved on the wing wheel 23 near the lower end;

[0033] As required, the surface of the strap is flush with the rolling surface of the impeller 23;

[0034] With this arrangement, the ventilator 1 is inserted into the mouth until it reaches the pharynx. The flange 22 can be pulled out or retracted according to the wearing situation. The elastically arranged wing wheel 23 prevents the user from feeling pinched on the cheek when wearing the ventilator. The cooperation between the head strap 24 and the neck strap 25 can fix the position of the ventilator 1 and prevent it from being dislocated during use.

[0035] like Figure 1 and Figure 2As shown, a separation patch 26 is pressed onto the connection of the head strap 24, and a closing patch 27 is pressed onto the neck of the neck strap 25;

[0036] As needed, the surface of the patch is made with anti-slip raised particles to prevent it from falling off during use;

[0037] This arrangement allows the patch to fit snugly against the skin, preventing the strap from being too thin and causing damage to the skin. At the same time, the patch can be fixed in place by contact with the skin thanks to the anti-slip bumps.

[0038] like Figure 4 As shown, a buckle 28 is embedded and installed on the rear surface of the separation patch 26, and the buckle 28 is separated and snapped in at an oblique direction of 45 degrees;

[0039] As needed, the surface of the buckle 28 is smoothed to prevent marks on the skin caused by prolonged use;

[0040] This arrangement allows the vent tube 1 to be separated and snapped in at 45° so that it can be fixed and separated only by pulling or snapping in the specified direction during use. It will not be directly separated by pulling horizontally, thus preventing the vent tube 1 from being dislocated by the child himself.

[0041] like Figure 4 As shown, a wheel groove is provided on the flange 22 at the installation position of the impeller 23. The depth of the wheel groove is greater than the width of the impeller 23. A stepped hole 29 is provided in the wheel groove along the bottom direction of the axial groove.

[0042] In this way, the wider wheel groove position wing wheel 23 provides a certain elastic range of movement, which allows the wing wheel 23 to move elastically, ensuring that it does not affect the rotation of the head during use and is used in an elastically fixed state;

[0043] Such as 1 and Figure 5 As shown, the edges of the flange 22 and the wing 21 are formed with stoppers that can fit together, and the edges of the flange 22 and the wing 21 are smooth and rounded;

[0044] In this way, the flange 22 and the wing 21 are provided with a fitting stopper, which can fix the flange 22 when it is pulled out to prevent it from falling off directly. The smooth rounded edge treatment of the flange 22 and the wing 21 can protect children from being scratched by the sharp edges during use.

[0045] like Figure 2 As shown, silicone patches are bonded to the skin-contacting surfaces of the separation patch 26 and the closure patch 27, the head strap 24 is an adjustable non-elastic strap, and the neck strap 25 is an elastic strap;

[0046] In this arrangement, the silicone patch is bonded to the patch, so that it does not cause allergies to the child's skin and can protect the child's skin. The neck strap 25 adopts an elastic design so that it is not affected when the neck moves. At the same time, the non-elastic head strap 24 can bind the head and will not fall off, causing the ventilation tube to fall off.

[0047] like Figure 3 As shown, the wing wheel 23 includes a rotating shaft 232 placed inside the stepped hole 29. One end of the rotating shaft 232 is formed with a round block, and the other end is rotatably connected to the wheel piece 231. A spring 233 is installed in the bottom section of the stepped hole 29.

[0048] With this arrangement, children's skin is relatively tender and easily broken. Since the wheel piece 231 can be elastically movable laterally, it can be adjusted to be active when worn by children with different face widths, ensuring that the children's skin can be protected;

[0049] As needed, a hard tooth pad is installed at the junction of the wing 21 and the ventilation tube 1, and the pharyngeal end of the ventilation tube 1 is smooth and rounded;

[0050] This arrangement can prevent the edges from scratching the skin during use, and the hard tooth pad part can be placed on the teeth to close and thus form a complete airway.

[0051] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
