Technical field

The present invention relates to an inflator, and more particularly to a hand held inflator for inflating a flexible object such as a balloon or a gas stick.

Background technique

In people's daily life, flexible objects such as balloons, swimming rings, inflatable sticks, etc. are often inflated, especially balloons, which are used to embellish our lives and bring us a lot of fun.

In the case of balloons, the earliest balloons are simply plastic products. People can inflate the balloons manually or mechanically, then fix the balloons in the room, or where they need to be decorated. However, this is only a basic use. As people's living standards improve, further decoration is required. Therefore, people later invented a lighting device or sounding device installed in a balloon, which is to light the bulb (or LED light) through the battery, thereby increasing the decorative effect of the balloon and being accepted by the majority of consumers. For example, a luminous balloon disclosed in Chinese Patent Application No. 200610122541.7, a luminous toy balloon disclosed in U.S. Patent No. 7,344,267.

Although the above balloon has a good decorative effect, it also has a significant defect, that is, the balloon needs to be inflated first, and the inflation can be performed by a special tool, or directly by the mouth, and then the balloon is sealed after inflation, which is for adults. There is no problem, but for children, it is not well mastered, which makes it inconvenient to use.

Therefore, Chinese Patent Application No. 201220229734.3 discloses a hand-held balloon device comprising a hand-held portion having an open cylindrical shape at both ends, and further comprising a mounting rod having an overall column shape, the mounting rod being hollow, the mounting rod a bottom end and a lower portion of the hand-held portion to form a detachable connection, the mounting rod The upper portion is slightly thin and has a small hole in the side wall communicating with the hollow portion, and a clamp portion is disposed on the outer wall of the mounting rod and between the small hole and the bottom end of the mounting rod, and the bottom end of the mounting rod is provided with a gas Check valve.

The patent application utilizes a specific device to facilitate the inflation of the balloon, which greatly facilitates the use of the person. However, the structure is also defective in that the intake air is realized through the small hole 3, and the small hole 3 is installed in the installation. On the side wall of the rod, the intake air is not smooth, and blowing is a little difficult. At the same time, the setting of the check valve greatly increases the complexity of the structure, and the light-emitting assembly 7 is connected to the upper end of the mounting rod and protrudes from the hand-held portion, which is not convenient for the The placement of the device, and the switch control cannot be realized during use.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Please refer to FIG. 1 , which is a first mode of implementation of the present invention. In this manner, a hand-held air blowing device for inflating a balloon or an inflatable rod realized by the present invention includes a casing 1 and a sealing sleeve 2 . The air blowing pipe 3, the casing 5, the lighting device (further including the LED lamp 4, the wire one 41, the wire two 42 and the battery 6), the tie rod 7 and the positioning block 8.

As shown in the figure, the upper end of the outer casing 1 has a flared opening; the air blowing pipe 3 is disposed in the outer casing 1 and fixed to the outer casing 1, and one end of the air inlet of the air blowing pipe 3 protrudes from the outer casing 1 and is extended. The part is expanded into a trumpet shape to facilitate assembly during assembly, and the trumpet-like structure is also convenient for people to place when not in use.

As shown in FIG. 2, the flared opening surface of the outer casing 1 is provided with a plurality of protruding stripes 11 which can reduce the contact surface of the balloon or the inflatable rod with the outer casing 1 when blowing, to reduce the balloon or the inflatable rod and the trumpet shape. The friction between the outer casings enables smooth inflation. The stripe 11 can be long or short, and only the contact area of the balloon and the flared opening of the casing can be reduced.

3 is a top view of another housing bell mouth of the present invention, in which a plurality of bumps 11 are uniformly disposed on the bell mouth of the outer casing 1, and the function of the bump 11 and the stripe 11 shown in FIG. 2 are identical.

Further, the bumps and the stripes can coexist, and the bell mouth can be provided with bumps and stripe at the same time, and the frictional force can be reduced and the inflation effect can be smoothly performed.

One end of the blow cylinder 3 is an air inlet, and one end is an air outlet (shown by an arrow in the figure), and the air inlet and the air outlet are on the same axis, so as to smoothly blow air. Normally, the blower cylinder 3 and the outer casing 1 are assembled in two parts, but in actual manufacture, the blower cylinder 3 and the outer casing 1 may be of a unitary structure. An illumination or sounding device is disposed on the end of the blower tube 3 at the flared opening of the outer casing 1. In the embodiment, the illumination device is an assembly of the LED lamp 4, the wire 41, the wire 42 and the battery 6; wherein, the LED The lamp 4 is concave on the outer edge of the flared opening, so as to protect the LED lamp 4 and facilitate the placement of the person; the lower part of the LED lamp 4 leads out two wires: the wire one 41, the wire two 42, the wire one 41 directly The battery 6 is electrically connected, and the wire 42 is wound from one side of the battery to the lower part of the battery, and an elastic wire 43 is formed at the lower portion of the battery. The elastic wire 43 can be held by the positioning block 8 to control the opening and closing of the LED lamp circuit. The entire lighting device is again placed inside the housing 5.

The illuminating device can also be replaced by other components or components such as a sounding device, which are existing products or structures, and will not be described herein.

A plurality of protruding ridges 31 are disposed on the outer wall of the middle portion of the blow cylinder 3, and the ridges 31 are convenient for fixing The lower part of the blower 3 is a small bell mouth 32, and the small bell mouth 32 protrudes from the outer casing to facilitate the installation of the air blower 3, and is also convenient for people to use the small bell mouth 32 for smooth placement during use.

The housing 5 encloses the LED lamp 4, the wire 41, the wire 42 and the battery 6 to form a protection for the above components and to facilitate connection and arrangement with other components. Therefore, the lighting device and the sealing assembly are movably disposed at the air outlet of the air blowing pipe 3. When the air is inflated, the lighting device and the sealing sleeve 2 open the air inlet passage, and the gas is put into the air. After the inflation is completed, the inside of the balloon or the inflatable rod is completed. Under pressure, the lighting device and the sealing sleeve 2 are sealed to the air outlet.

The sealing sleeve 2 is a cover-like object, and can be directly sleeved on the LED lamp 4. At the same time, the outermost outer diameter portion of the sealing sleeve 2 is also sleeved with an elastic annular O-ring 21, and the O-ring 21 can ensure the sealing sleeve 2 Has a good sealing performance.

The lower portion of the housing 5 protrudes outwardly to form an annular convex portion 51. An upper fastening head 71 is fastened to the convex portion 51. At the same time, the lower fastening head 72 is supported on the bottom surface of the housing 5; Both the 71 and the lower buckle 72 are part of the tie rod 7. The pull rod 7 extends along the blow cylinder 3, and an annular pull handle 73 is formed at the air inlet end of the blow cylinder 3, and the handle 73 facilitates the control of the pull rod.

Usually, the pressure inside the balloon or the blowing rod will seal the sealing sleeve 2 to the air outlet of the blowing cylinder 3, but the sealing may not be very tight, so in order to perform a tight sealing, after blowing, people can pass down. Pulling the pull rod 7 causes the upper buckle 71 to drive the housing 5 downward to ensure that the O-ring 21 is tightly sealed to the air outlet; when the air is required to be deflated, only the pull rod 7 needs to be lifted upward, and the lower buckle 72 pushes the housing 5 is moved upward so that the O-ring 21 is released from contact with the blow cylinder 3, and the inflation passage is opened to discharge the gas, whereby the balloon or the inflatable rod can be used multiple times.

In order to control the lighting or extinction of the LED lamp 4, there is a positioning block (that is, a positioning member) 8 above the tie rod 7, and the positioning block 8 is located below the battery 6 and the elastic wire 43, and can be held by the elastic wire 43. Pulling the pull rod 7 downward, the pull rod 7 drives the housing 5 to move downward, and the elastic wire 43 is held by the positioning block 8 to contact the battery 6, and the circuit is turned on to light the LED lamp 4; the pull rod 7 is pushed up, The pull rod 7 drives the housing 5 to move upward, and the elastic wire 43 is disengaged from the positioning block 8 and is no longer held by the positioning block 8. Thereby, the elastic wire 43 is elastically reset, no longer contacts the battery 6, disconnects the circuit, and extinguishes the LED lamp 4. .

The method for controlling the opening and closing of the LED lamp 4 can be realized not only by the tie rod 7, but also by an insulating material, for example, an insulating material tape is disposed between the wire 42 and the battery 6, thereby isolating the electrical connection, when in use. Pulling out the strip of insulating material can also achieve the purpose of illuminating the LED lamp 4.

FIG. 4 is another implementation manner of the hand-held air blowing device for inflating a balloon or an inflatable rod according to the present invention. In this implementation, the basic structure is the same as that shown in FIG. 1 , so the same structure is used. I will not go into details here, but only the different parts.

The sealing sleeve 2 can be made of an elastic plastic material, whereby the sealing sleeve 2 can be deformed, and only the sealing sleeve 2 is fixed to the outside of the lighting or sounding device, so that the sealing effect can be achieved.

Next, in the middle of the tie rod 7, a rotating body 75 is provided. The rotating body 75 is connected to the upper buckle 71 and the lower buckle 72 through the connecting portion 74. The outer wall of the rotating body 75 has a threaded structure 76 while being in the air blowing tube 3. The inner wall is provided with a corresponding thread structure, and the thread structure 76 of the rotating body 75 cooperates with the thread structure of the air blowing pipe 3, so that the rotation control can be realized to achieve the purpose of controlling the up and down movement of the casing 5. This is because many people are inconvenient to push and pull the tie rod 7 when in use, and therefore, the control of the tie rod 7 can be realized by rotating the handle 73.

At the same time, the manner of the rotation control is not only applicable to the structure of the tie rod 7, but also can be changed to the knob by the pull rod 7, and also has the effect of controlling the up and down movement of the casing 5.

In the embodiment shown in FIGS. 1 and 4, the outer casing 1 substantially covers the outside of the blow cylinder 3, and the blow cylinder 3 is housed in the outer casing 1, that is, the blow cylinder 3 is disposed in the outer casing 1, but this It does not mean that the invention is implemented in all its forms. In other conceivable ways, the outer casing 1 can cover one half of the blower cylinder 3, or more than half, as long as one end of the air outlet of the blower cylinder 3 is located in the outer casing 1. And the flared opening of the outer casing 1 can be disposed outside the blower cylinder 3, and the illumination or sounding device can be recessed on the outer edge of the flared opening, or the air inlet of the blower cylinder 3 is not flush with the outer casing 1. Rather, the air inlet of the blower 3 is located within the housing as shown in FIG.

The structure of FIG. 5 is basically the same as that of FIG. 1, and the same portions will not be described again here, except that the blower cylinder 3 is retracted into the outer casing 1, and the intake end of the blower cylinder 3 (indicated by an arrow in the figure) is located in the outer casing. In the middle portion, at the same time, the inner wall of the outer casing 1 is provided with a card table 12 protruding inwardly, and the air blowing tube 3 is fixed by the card table 12, This structure facilitates assembly of the blower 3 and the balloon or the inflator.

During use, the balloon is usually mounted on the outer wall strip 31, and the balloon is easily fixed in conjunction with the friction of the balloon itself.

Referring to FIG. 6 again, another schematic structural diagram of the present invention is implemented. In the figure, the main structure of the mode is the same as that shown in FIG. 1 , except that the illumination or sounding device is not disposed in the casing 5 . That is to say, there is only one housing 5, and the outer surface of the casing is covered with the sealing sleeve 2. Similarly, the middle ring of the sealing sleeve 2 is sleeved with an O-ring 21, which is sealed by the casing 5, the sealing sleeve 2 and the O-ring 21.

The lower portion of the housing 5 protrudes outward to form an annular convex portion 51. The upper buckle 71 of the pull rod 7 is fastened to the convex portion 51. At the same time, the lower buckle 72 is supported on the bottom surface of the housing 5, and the pull rod 7 is pulled. Extending along the blow cylinder 3, an annular handle 73 is formed at the inlet end of the blow cylinder 3, and the handle 73 facilitates the control of the tie rod.

A plurality of protruding ridges 31 are disposed on the outer wall of the middle portion of the blow cylinder 3, and a small bell mouth 32 is formed on the lower portion of the blow cylinder 3, and a pull ring 9 is disposed on the outer wall of the small bell mouth 32, and the pull ring 9 is used for the sleeve Binding a rope or the like facilitates the association of the hand-held air blowing device implemented by the present invention with other objects.

After blowing, the pressure in the balloon or the air blowing rod seals the sealing sleeve 2 to the air outlet of the air blowing cylinder 3. For tight sealing, the upper buckle 71 can be driven to move the housing 5 by pulling the pulling rod 7 downward. The lower displacement ensures that the sealing sleeve 2 is tightly sealed to the air outlet; when it is required to deflate, only the pull rod 7 needs to be lifted upwards, the lower buckle 72 will push the housing 5 upward, thereby making the housing 5, the sealing sleeve 2 and The O-ring 21 is disengaged from the blow-in cylinder 3, and the gas passage is opened to discharge the gas, whereby the balloon or the inflator can be used multiple times.

It can be seen that the structure realized by the present invention can be equipped with a lighting device or a sounding device inside the casing, or a similar device, or nothing, the casing is only used as a part of the sealing assembly, or the casing is used as a Seals.

In summary, the present invention is improved by the above-mentioned structure. Firstly, the air passage is held in a straight line by the arrangement of the air blowing cylinder, and rapid inflation can be realized; and the housing, the lighting device or the sounding device provided in combination with the movable device is effective for the inflation passage. Sealed so that people can carry objects such as balloons and inflatable rods Inflated.

The movement of the control housing 5 realizes the opening and closing control of the lighting device or the sounding device, which is very convenient for people to use multiple times. Therefore, the balloon or the inflatable rod can be reused, thereby avoiding waste of resources, and more importantly, By the invention, the balloon or the inflatable rod can be replaced, and the required balloon or the inflatable rod can be replaced at will, which is very beneficial for saving resources and protecting the environment.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. Within the scope.
