Description

Inflatable nozzle device (2)

The present invention provides an aeration nozzle device (2) having two technical features:

1. The present invention can prevent the formation of a "air plug" inside when the test is performed without connecting the inflatable member.

2. The present invention can improve the large amount of deflation of the inflatable member when the inflatable member is to be separated from each other after the air is exhausted, or before the inflatable member is turned on to be inflated.

Referring to FIG. 1A, an inflation nozzle device for preventing a "air plug" from being formed inside is disclosed. The inflation nozzle device is mounted with a cylinder block (92) and a cylinder block (92) at the bottom of the headstock (91). a first air nozzle (93A) pressed, a second tuyeres (93B) pressed by the cylinder block (92), and a top end (91) is pivotally provided with a wrench (95) having a cam (951), and A valve body (94) is mounted between the cylinder (92) and the wrench (95), so that the cam (951) of the wrench (95) can drive the valve body (94) to limit the downward pressing cylinder (92) So that the cylinder (92) can act on the two tuyeres (93A) (93B), as shown in Fig. 1B, so that the positioning holes (931) of the first tuyeres (93A) are connected to the French inductive members. The nozzle (FV) and the positioning hole (932) of the second tuyeres (93B) have an American nozzle (not shown) that entrains the inflator; the valve body (94) has an intake hole that communicates with the inflator (941). And the valve body (94) is further provided with a first air chamber (96A) and a second air chamber (96B), so that the first air chamber (96A) can mediate the air inlet hole (941) and the first air nozzle ( 93A) the positioning hole (931) and the second air chamber (96B) can mediate the air inlet hole (941) and the second air nozzle (93B) positioning hole (932), and at the first Chamber (96A) is mounted in a first valve member (97A), a second plenum mounting (96B) of There is a second valve member (97B) whose first valve member (97A) is pressed downward by the first spring (971) to close the first air chamber (96A) and the second valve member (97B) is subjected to the second spring (972) Pressing down to close the second air chamber (96B): In addition, the valve body (94) is further provided with a gas discharge valve capable of normally opening the air inlet (941) at a position corresponding to the wrench (95) cam (951) ( 98) However, when the wrench (95) drives the valve body (94) to press the cylinder (92) downward, the cam (951) can control the shutoff valve (98) to close.

As shown in FIG. 1A, when the inflator is not connected to the inflator, and the inflator (for example, the hand pump) is tested to provide the air pressure of the air inlet (941), the air pressure can directly pass through the air release valve (98). Discharge, thus preventing the formation of "air plugs" inside the aeration nozzle device.

Referring to FIG. 1B, when the inflation nozzle device intends to inflate the inflatable member, the French nozzle (FV) provided by the inflatable member must be inserted into the positioning hole (931) of the first tuyeres (93A) to make the French connection. The mouth (FV) can overcome the preset spring force of the first spring (971) for pushing up the first valve member (97A) to move upward to open the first air chamber (96A), and the first valve member (97A) can Open the valve inside the French spout (FV), then turn the wrench (95) to force the cam (951) to close the bleed valve (98), then force the valve body (94) to move down, so that the French spigot ( FV) can be clamped in the first air nozzle (93A) positioning hole (931), and then the air inlet (941) air pressure is provided together with the inflator, so that the air pressure input by the air inlet hole (941) can be made. It can be forced into the inflatable member through the first air chamber (96A) and the French nozzle (FV).

Please cooperate with Figure 1C. When the inflatable parts are fully pumped, the wrench (95) must be turned. Reset, and return the valve body (94) to the origin to release the first tuyeres (93A), and the unopened nozzles (FV) are clamped, and then the French nozzle (FV) can be pulled out. However, when the wrench (95) is released to release the valve body (94), the bleed valve (98) will be in a normally open state. At this time, the French spigot (FV) is too late to be pulled out, and the first valve member ( 97A) is still in the state of opening the French mouth (FV) shutter, so that the air pressure inside the inflatable member will overflow through the French nozzle (FV), the first air chamber (96A), and the air release valve (98). The problem of reducing the air pressure inside the inflatable member is caused; the same reason, when the French nozzle (FV) is inserted into the first tuyeres (93A), the first valve member (97A) is opened, and in the case of the French mouth (FV) Before the pumping, at this time, the French nozzle (FV) will also release the internal pressure of the inflatable member.

Since the diameter of the French mouthpiece (FV) is larger than that of the general American mouthpiece, the momentary pressure relief situation is quite serious. In view of this, the inventor has years of professional experience and experience, and has been conceived and researched. The present invention has been developed to improve the aeration nozzle device which can improve the "air lock" so as to effectively reduce the instantaneous deflation amount before the separation of the inflatable member.

The main content of the present invention is to provide an aeration nozzle device (2), comprising: a head base extending upwardly around the bottom plate with a crotch portion for defining an assembly chamber, the bottom plate further extending through the assembly chamber a first air hole; a first air nozzle on the bottom end of the bottom plate, and a first positioning hole for inserting the French nozzle; the first positioning hole and the first air hole are connected to each other; a cylinder in the chamber that abuts against the top end of the first tuyeres, the cylinder The first cylinder bore is connected to the first positioning hole, and the top surface of the cylinder body is further formed with a back pressure flow passage communicating with the first cylinder bore; a first cylinder bore is mounted a first valve member having a shoulder capable of closing the first cylinder bore and having a thimble extending into the first positioning hole, the ejector shape being capable of correspondingly opening the French nozzle, and the top of the first valve member a first spring is disposed; a valve body limited to the assembly chamber, having an air inlet for inflating the air inflator, and having a receiving hole and a lower receiving hole connected to the air inlet, the lower receiving hole is connected A plug body is arranged above the back pressure flow passage, and a plug body is installed in the lower receiving hole, so that when the plug body is supplied with the back pressure flow passage, the plug body can be moved up to close the lower receiving hole; in addition, the valve body is more capable of Providing a first spring positioning for enabling the first spring to provide a downward predetermined elastic force to the first valve member, so that the first valve member shoulder can close the first cylinder bore; a normally open bleed valve Mounted in the upper receiving hole; and a wrench, one end of which is pivoted on the top edge of the head seat, and the outer circumference of the end of the wrench is formed Cam, the cam system at the top of the valve body to limit, and can release valve closed when rotated to continue urging the valve body downward to be interposed French mouthpiece and pump beam.

Therefore, after the air pumping is completed, the wrench cam release valve body and the air release valve must be operated, but when the French nozzle is too late to be pulled out, the air pressure inside the French nozzle will flow into the back pressure flow passage, so that it can be The closed lower receiving hole for pushing the plug body up, thereby preventing the air pressure inside the inflatable member from deflation, thereby greatly improving the disadvantage that the conventional French nozzle is easy to release a large amount of pressure after pumping; the same reason, when the French nozzle is inserted In the first tuyeres, and before we pump the French nozzles, the present invention can also improve the leakage of the internal pressure of the French nozzles.
