The air tube 50 is connected with the air valve 40, and the air valve 40 is used for deflating, so that the air pressure in the air tube 50 is changed, and the air pressure of the air bag is influenced. Since the air valve 40 includes the stepping motor 410, the valve body 420 and the valve body 430, the stepping motor 410 can be rotated forward and backward, so that the opening and closing of the valve body 420 and the valve body 430 can be realized.

The outlet is therefore typically provided as a plurality of air holes, the opening and closing of which is controlled by a solenoid valve so that each air bag of the air bag member is sequentially inflated.
The air valve 40 of the present utility model includes a stepper motor 410, a valve body 420 and a valve core 430, which is different from the multi-connected valve used in the prior art, and has lower cost. Because the multiple valve is essentially composed of a plurality of solenoid valves, it is much more expensive to manufacture than the valve 40 of the present utility model.
In some specific embodiments, referring to fig. 5 and 6, the inner portion of the valve body 420 is funnel-shaped, an internal thread (not shown) is provided inside the valve body 420, the valve core 430 includes a head portion 4310 and a tail portion 4320, the head portion 4310 is provided with an external thread (not shown) adapted to the internal thread (not shown), the head portion 4310 abuts against the tail portion 4320, and the tail portion 4320 can abut against the funnel-shaped portion inside the valve body 420.
In this embodiment, the part in the valve body 420 is funnel-shaped, the head 4310 of the valve core 430 is driven to rotate by the stepper motor 410, and since the head 4310 is provided with external threads and the inner wall of the valve body 420 is provided with internal threads (not shown), the rotation of the head can make the valve core 430 complete the telescopic action in the valve body 420. Closing the valve 40 can be achieved by abutting the tail 4320 of the valve element 430 against a funnel-shaped portion in the valve body 420, and when the head of the valve element 430 drives the tail 4320 to rotate away from the inner wall of the valve body 420, the valve 40 is opened. The degree of opening of the gas valve 40 is controlled by controlling the size of the gap between the tail 4320 and the valve body 420.
It should be noted that the air valve 40 in the present utility model may have other structures to achieve the purpose of linearity of the output power of the portable air wave pressure therapeutic apparatus in the present utility model.
Specifically, the air valve 40 may adopt a butterfly valve structure, and the stepping motor 410 drives the valve body 430 to rotate to open the valve body 430 of the butterfly valve.
Therefore, it is within the scope of the present utility model to achieve a valve that controls the degree of opening of the gas valve 40.
In some embodiments, referring to FIG. 6, the tail 4320 is provided with a ring of sealing rings 4340.
The tail 4320 is sleeved with a layer of sealing ring 4340, and the sealing ring 4340 can be abutted against the inner wall of the valve body 420, so that the sealing effect is enhanced.

In the present embodiment, the elastic member 4350 is used to prevent the tail 4320 from excessively abutting against the inner wall of the valve body 420, so that the valve body 420 bursts. When the stepper motor 410 rotates, the head-driving tail 4320 abuts against the inner wall of the valve body 420, and the elastic member 4350 can play a role of buffering. Thus, the error range for the number of rotations of the stepping motor 410 can be large.
In general, the elastic member 4350 is preferably a compression spring.
In some embodiments, referring to fig. 4, the air conditioner further includes a first air pressure sensor 210, where the first air pressure sensor 210 is disposed at the air outlet 510 and connected to the control structure 20.
Basic principle of air pressure sensor:
The primary sensing element of some barometric pressure sensors is a pressure sensitive membrane to which a flexible resistor is connected. When the pressure of the measured gas decreases or increases, the thin film is deformed, and the resistance of the resistor is changed. The resistance of the resistor changes. The signal voltage of 0-5V is obtained from the sensing element, is received by the data acquisition unit after A/D conversion, and then the data acquisition unit transmits the result to the computer in a proper form.
The main component of some barometric sensors is a varactor-type silicon capsule. When the external atmospheric pressure of the positive-displacement silicon capsule changes, the single crystal silicon capsule elastically deforms along with the change of the external atmospheric pressure, so that the capacitance of the silicon capsule parallel plate capacitor changes.
In this embodiment, the first air pressure sensor 210 is connected by a hose 520, so that the air pressure sensor can sense the air pressure of the air outlet 510 and transmit air pressure data to the control structure 20. The air pressure data collected by the first air pressure sensor 210 is actually the external output power of the portable air wave pressure therapeutic apparatus in the present utility model. The patient can directly set the specified intensity (air pressure) and the control structure 20 automatically controls the air valve 40 until the air pressure data collected by the first air pressure sensor 210 is the same as the air pressure data required by the patient.
In some embodiments, a second air pressure sensor 220 is further included, the second air pressure sensor 220 being disposed between the air outlet 510 and the air valve 40 and being coupled to the control structure 20.
The second air pressure sensor 220 is used to measure the air pressure at the air valve 40 and transmit data to the control structure 20. The control structure 20 can more quickly calculate the rotation direction and angle of the stepper motor 410 of the outlet valve 40 by the combination of the second air pressure sensor 220 and the first sensor.
The main reason is that the air flow throughput of the air valve 40 is curved with the rotation angle of the stepper motor 410. Thus, the second air pressure sensor 220 is required to be matched so as to more quickly bring the air pressure of the air outlet 510 to the set value of the patient.
In certain embodiments, referring to fig. 3-4, the air tube 50 is formed by interconnecting a plurality of lengths of flexible tubing 520 and a plurality of connectors 530.
In this embodiment, the connecting member 530 is typically a tee or a fixed pipe. A plurality of hoses 520 are inserted into the connection members 530 to form a pipe so as to connect the air pump 30, the air outlet 510, and the air valve 40.
In some embodiments, please refer to fig. 1 and 2, which include the air lock 120, the number of air outlets 510 is plural, and the air lock 120 can block part of the air outlets 510.
Since different sizes of balloon members typically have different numbers of balloons, typically 4-8 balloons. Referring to fig. 1 and 2, there are 4 air outlets 510 up and down, and one air plug 120 may block the four air outlets 510 up or down. When there are only 4 balloons in the balloon member, only one balloon plug 120 need be used. When there are 6 or 8 balloons in the balloon member, all the plugs 120 are pulled out.
In some embodiments, referring to fig. 1 and 2, the housing 10 is provided with a plug station 140 for receiving the plug 120.
In this embodiment, when the portable airwave therapeutic apparatus of the present utility model is not required, all of the air plugs 120 are used to avoid dust from blocking the air outlet 510. When it is desired to use the portable airwave therapeutic apparatus of the present utility model, the air lock 120 is placed in the air lock position 140 on the housing so as to prevent the air lock 120 from being lost.
Generally, the air plug 120 and the air plug position 140 are provided with mutually matched clamping structures, so that the air plug 120 is clamped at the air plug position 140, and the air plug 120 is prevented from falling.
It should be noted that, the number of the air outlets 510 and the number of the air plugs 120 capable of blocking the air outlets 510 are not limited, so long as the above functions can be achieved, which falls within the scope of the present utility model.
In some embodiments, referring to fig. 1, the housing 10 includes a key 130 and a display 150, and the key 130 and the display 150 are electrically connected to the control structure 20.
The key 130 can enable the patient to select to set a specific external output air pressure, and the display screen 150 displays a specific air pressure value, so that the patient can accurately select the air pressure externally output by the air wave therapeutic apparatus.
Finally, referring to fig. 3, the portable electronic device further includes a battery 60, and the battery 60 can be self-powered and free from the constraint of a power source, thereby realizing the portable function.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
