Problems solved by technology

Therefore, the gas control device (device) disclosed above has a fast deflation speed at high pressure, and slows down the deflation speed after the pressure becomes low, or even stops at a certain air pressure (such as 30mmHg), and finally cannot achieve the effect of "rapid discharge". It can't even meet the requirement of "the decompression time from 260mmHg to 15mmHg shall not exceed 10 seconds" stipulated in the standard of electronic sphygmomanometer

Embodiment 1

[0054] Please refer to figure 1 , the gas valve includes a valve housing 105, a cover body 106 and a base plate 107, the cover body 106 and the base plate 107 are respectively located on the upper and lower sides of the valve housing 105, and are stacked in sequence.

[0055] Please refer to Figure 1-3 , The valve housing 105 includes an inlet valve housing 21 and an exhaust valve housing 31. The inlet valve housing 21 and the exhaust valve housing 31 may be provided independently or in an integrated structure. The intake valve housing 21 has an intake valve chamber, and the exhaust valve housing 31 has an exhaust valve chamber.

[0056] A partition 20 is provided in the intake valve chamber, and the partition 20 divides the intake valve chamber into a first valve chamber 26 and a second valve chamber 23 . The first valve chamber 26 is provided with a first air inlet 24 , and the second valve chamber 23 is provided with a first connection port 27 .

[0057] The air valve 1...

Embodiment 2

[0080] Please refer to Figure 7-9 The main difference between the air valve provided in the second embodiment and the air valve shown in the first embodiment is that the first valve chamber and the third valve chamber are connected to form an integrated first space 226, the second valve chamber and the fourth valve chamber The chambers communicate with the integrally formed second space 223 .

[0081] On the valve housing 231, an air inlet 211 communicating with the discharge hole 101A of the air pump 101 is formed (in this embodiment, the original first air inlet and the second air inlet are combined into one air inlet 211), and The connection port 212 that the cuff air bag 110 communicates (in this embodiment, the original first connection port and the second connection port are combined into one connection port 212), the exhaust port 213 communicated with the outside of the air valve 200, the first The vent hole 218 communicating with the space 226 and the second space 22...

Embodiment 3

[0086] Please refer to Figure 10-13 The main difference between the air valve provided in the third embodiment and the air valve shown in the second embodiment lies in the structure of the elastic body. The elastic body provided in the third embodiment is a barrel-shaped elastic body 309, the opening end of the barrel-shaped elastic body 309 faces the first space 326, and the sealing end of the barrel-shaped elastic body 309 extends into the second space 323, and the barrel-shaped elastic body 309 The barrel wall (side wall and / or bottom wall) of the body 309 protruding into the second space 323 is provided with a notch 309A that is only deformed and opened in the direction of the second space 323 .

[0087] Specifically, an air inlet 311 communicating with the discharge hole 101A of the air pump 101, a connecting port 312 communicating with the cuff airbag 110, an exhaust port 313 communicating with the outside of the air valve 300, and a valve housing 331 are formed. The v...

Abstract

The invention discloses an air valve, an integrated air pump and a wearable electronic sphygmomanometer. The air valve, the integrated air pump and the wearable electronic sphygmomanometer have the advantages that an ventilation opening is formed between a first space and a second space of the air valve, and ventilation flow of the ventilation opening is smaller than air inlet flow of an corresponding air inlet; when an air pressurization unit (for example, the air pump) stops pressurization, the first space is communicated with the second space through the ventilation opening, air pressure of the first space becomes the same as air pressure of the second space, and a channel for connecting the second space to the outside is opened by an exhaust valve to enable air in a sleeve belt air bag to be exhausted rapidly, so that rapid exhaust can be achieved without addition of additional vent valves; the air valve is simple in structure, can be downsized into a certain size and is applicable to wearable devices such as the electronic sphygmomanometer same as a common watch in size.

Description

technical field [0001] The present application relates to an electronic sphygmomanometer, in particular to an air valve and an air pump in the electronic sphygmomanometer. Background technique [0002] A Chinese patent application (publication number CN 103140166 A) entitled "Valve, Fluid Control Device" discloses a valve and a fluid control device. The fluid control device consists of a pump and a valve. The pump has a pump chamber, and a suction hole and a discharge hole that communicate with each other via the pump chamber. [0003] The air valve includes a valve housing, a valve housing and a diaphragm, and the diaphragm divides the valve housing into a first area and a second area. Thus when the pressure in the first area is higher than the pressure in the second area, the first area communicates with the second area through the main vent hole, and the second area is blocked from the ventilation channel of the outside world; when the pressure in the first area is high...
