Fluid control device

The present invention "fluid control device" relates to a technical field for controlling different aspects of airbag changes in inflation, maintaining the status quo or exhausting.

Medical air bed, designed for patients to stay in bed for a long time to prevent skin due to long-term pressure, there will be acne, the air bed is an air pump to inflate the air bed. After the airbed is lying on the patient, the pressure is different according to the patient's body shape, body weight, and the pressure of the air bed corresponding to each part of the human body, so the air bed is mostly designed to be juxtaposed by a plurality of independent airbag strips. Therefore, each airbag strip can adjust the internal air pressure to an appropriate one according to different needs. The pressure regulating structure of the conventional airbag is mostly disposed in the covering structure of the air bed, which is quite troublesome when the pressure is adjusted, and the entire covering structure needs to be opened, and the pressure regulating structure only has two functions of air flow passage or open circuit, and the airbag is used as the airbag. If the internal pressure is too large, or when there is a need for CPR first aid, there is no pressure relief function, resulting in many limitations and defects in the actual use of the air bed.

Obviously, the existing air bed pressure regulating structure is still not ideal and perfect, and it is necessary to improve. In view of this, the creators have specially researched and created the cost case, and can use the proposal of this case to improve the existing shortcomings, so that the pressure regulating function of the air bed can be more perfect and ideal, and meet the actual needs.

In order to improve the functional limitations and lack of the above-mentioned air bed pressure regulation, the main purpose of the creation of the "fluid control device" is to provide a control device which is arranged between the inflatable pump and the air bag to control the air bag change. In the case of inflating, maintaining the status quo or exhausting, the air pressure in the airbag can be supplemented when the pressure in the airbag is insufficient, and the air pressure in the airbag is too large or the CPR emergency can be used to excrete air when the airbag pressure is appropriate or When the air bed needs to be moved, it can be stopped to maintain the status quo; thereby achieving the practical purpose of multi-functionality.

In order to achieve the above object, the specific method of the present invention is: the fluid control device includes a first body, a second body and a rotating body, the rotating body is sandwiched between the first body and the second body and can Rotating, the first body can be integrated with the second body.

The first body is provided with a first tube body and a second tube body, the first tube body is juxtaposed above the second tube body, and the first tube system is used for connecting the airbag of the air bed The second tube system is used to connect to the pump. The first inner tube end of the first tube is provided with a first channel having a concave shape, and the first channel is slightly curved, and a first oil seal is disposed around the inner surface of the first inner body; The inner end of the inner tube of the second tube passes through the opposite inner edge surface of the first body, and is provided with a second channel having a concave shape. The second channel is slightly circular, and a second oil seal is disposed around the second channel.

The second body is provided with a shaft hole in the center, and a third channel is disposed on the second body inner surface below the side edge of the shaft hole. The third channel is slightly curved, and a periphery is disposed. Three oil seals; above the shaft hole A venting opening is provided, and a fourth oil seal is disposed on the inner edge of the venting opening.

The rotating body has a circular plate piece, and a shaft member extends from the center of the edge surface and passes through the shaft hole of the second body. The pivoting body has a control component, so that the control component can be used for linkage. The rotating body has a first through hole and a second through hole.

The first through hole and the second through opening can be connected to the first channel, the second channel, the third channel, and the air outlet according to the state when the rotating body performs a circular motion.

In view of the structural composition of the creation of the "fluid control device" and the effects it can produce, the preferred embodiment of the present invention is described in detail below.

Referring to the first, second and third figures, the fluid control device of the present invention comprises a first body 1, a second body 2 and a rotating body 3, and the rotating body 2 is sandwiched between First body 1 and second book The body 2 is rotatable, and the first body 1 can be integrated with the second body 2.

The first body 1 is provided with a first tube body 11 and a second tube body 12, and the first tube body 11 is juxtaposed above the second tube body 12. The first tube body 11 is The air tube 41 is connected to an air bag (not shown) of the air bed, and the second tube 12 is connected to the pump (not shown) via a gas pipe 42. The inner end of the first pipe body 11 is disposed through a first inner groove surface of the first body 1 and has a recessed first channel 13 . The first channel 13 is slightly curved and has a first periphery. An oil seal 131; a second groove 14 is formed in a recessed shape, and the second channel 14 is slightly rounded, and the inner end of the second pipe body 12 is opposite to the inner edge surface of the first body 1. A second oil seal 141 is disposed. The second body 2 is provided with a shaft hole 20 in the center, and a third channel 21 is formed on the inner surface of the second body 2 below the edge of the shaft hole 20. The third channel 21 is slightly curved. A third oil seal 211 is disposed on the periphery; a venting opening 22 is disposed above the shaft hole 20, and a fourth oil seal 221 is disposed on the inner edge of the venting opening 22. The rotating body 3 has a circular plate piece. A shaft member 30 extends from the center of the edge surface and passes through the shaft hole 20 of the second body 2. The control element 33 is pivoted to the control element 33. The rotating body 3 can be used to link the rotating body 3; and the rotating body 3 is provided with a first opening 31 and a second opening 32.

When the present invention is implemented, as shown in the fourth figure, when the end of the control element 33 is directed downward, the first channel 13 is not connected to any of the openings with respect to the rotating body 3, so the first channel 13 is closed. The air flow in the first pipe body 11 is not changed; and the second pipe body 12 is connected to the second opening 32 because of the second channel 14 thereof, but the second opening 32 is only related to the second port 32. The third channel 21 in the closed state is connected, so the air flow in the second pipe 12 is also failed. Any changes are made, at this time to maintain the status quo.

Referring to the fifth figure, when the end of the control element 33 is directed to the nine o'clock direction on the left side of the drawing, the rotating body 3 is also rotated 90 degrees to the left, and the first opening 31 and the second are The channels 14 abut and communicate, so that the air generated by the pump can enter the second channel 14 through the second pipe body 12 through the first opening 31 into the lower half of the third channel 21, and due to the third The upper half of the channel 21 is in turn in communication with the second opening 32, so that air will pass through the upper half of the third channel 21, through the second opening 32, into the first channel 13, and finally The first tube body 11 is entered to achieve the purpose of inflating the rear end air bag.

Referring to the sixth figure, when the end of the control element 33 is directed to the right side of the drawing at the three o'clock direction, the first opening 31 will penetrate with the first channel 13 and the venting port 22, which is originally located in the first tube. The air in the body 11 will be discharged from the air outlet 22 via the first channel 13 and the first opening 31, which is the discharge operation of the air bag; at this time, the second end of the second tube 14 is second. The channel 14 is blocked by the rotating body 3.

In summary, the "fluid control device" of the present case is rotated in a simple structure, that is, three different states of use can be achieved, which fully meets the actual needs; the volume is small, does not occupy space, and has good air tightness.
