Problems solved by technology

The disadvantage is that the helical solenoid valve consumes a lot of power, which is very unfavorable especially for electronic sphygmomanometers using dry batteries. At the same time, it will also have a certain impact on environmental pollution.
And because the total volume of the air pump and the solenoid valve is too large, it cannot be used in a wearable electronic sphygmomanometer

Embodiment 1

[0059] Embodiment 1 provides an air release valve, which includes an upper cover, a lower cover and an elastic body.

[0060] The upper cover has an upper cavity, an air outlet and an air release port, the upper cavity is formed by a sidewall depression on one side of the upper cover, and the air outlet and the air release port communicate with the upper cavity. The lower cover has a lower cavity and an air inlet, the lower cavity is formed by a sidewall depression on one side of the lower cover, and the air inlet communicates with the lower cavity.

[0061] The upper cover and the lower cover are fixedly connected in such a way that the upper cavity and the lower cavity are opposite, and the elastic body is clamped between the upper cover and the lower cover, which divides the upper cavity and the lower cavity into an upper air chamber and a lower air chamber. The elastic body has a vent hole through which the upper air chamber and the lower air chamber communicate.

Embodiment 2

[0066] Please refer to Figure 1-6 , the present embodiment provides a mechanical deflation valve, which specifically includes an upper cover 1 , an elastic body 2 and a lower cover 3 .

[0067] The upper cover 1 has an upper cavity a1, an air outlet 11 and an air release port 12, the upper cavity a1 is formed by a sidewall depression on one side of the upper cover 1, and the air outlet 11 and the air release port 12 communicate with the upper cavity a1. The lower cover 3 has a lower chamber b1 , an air inlet 31 and a boss 32 , the lower chamber b1 is formed by a sidewall depression on one side of the lower cover 3 , and the air inlet 31 communicates with the lower chamber b1 .

[0068] Such as Figure 5 As shown, the upper cover 1 and the lower cover 3 are fixedly connected in such a way that the upper cavity a1 and the lower cavity b1 are opposite, the elastic body 2 is clamped between the upper cover 1 and the lower cover 3, and the upper cavity a1 and the lower cavity Th...

Embodiment 3

[0075] The deflation valve provided by the first embodiment above has a simple structure and is a purely mechanical deflation. Here, it can also be built into an ordinary pressurized air pump, located in the air outlet passage of the air pump, to form an integrated air pump with a rapid deflation function.

[0076] Please refer to Figure 7-11 , the third embodiment provides an example of an integrated air pump based on the above inventive concept.

[0077] The integrated air pump includes a deflation part 100 and a pressurization part 200 . Figure 7-11 The reference numbers starting with the number 1 are all included in the deflation part 100, and the numbers starting with the number 2 are all included in the pressurizing part 200.

[0078] The deflation portion 100 includes such a deflation valve as provided in the present application.

[0079] Specifically, the deflation valve in the third embodiment includes an air nozzle 110 (equivalent to the upper cover 1 in the sec...

Abstract

The invention discloses a vent valve, an integrated air pump and an electronic sphygmomanometer. An upper cover, a lower cover and a resilient body in the vent valve form an upper air chamber and a lower air chamber, the two air chambers are communicated with each other only through vent pores on the resilient body, a vent port of the upper cover is communicated with the upper air chamber to form an normally-open check valve which is communicated with exterior, the lower cover and the resilient body form the lower air chamber on the vent pore to be led to a normally-closed check valve of the upper air chamber, when the air pressure in the lower air chamber is greater than that in the upper air chamber, the resilient body is deformed towards the upper air chamber so as to block the normally-open check valve, the normally-closed check valve is opened, so that the opening and closing of the normally-open check valve and the normally-close check valve can be realized through the resilient deformation of the resilient body, and the air intake function and the ventilation function can be realized. The structure is the pure mechanical structure, and no electric energy is consumed. Due to the small size, the integrated air pump is applicable to the wearable electronic sphygmomanometer.

Description

technical field [0001] The present application relates to the field of electronic sphygmomanometers, in particular to the design of the air circuit system in the structure of the electronic sphygmomanometer, and further, to the design of the air circuit system in the structure of the wearable electronic sphygmomanometer. Background technique [0002] When people use an electronic sphygmomanometer to measure blood pressure, after the measurement is completed, the compressed gas in the air bag of the cuff or wristband needs to be discharged. At present, people use a helicoid solenoid valve in the electronic sphygmomanometer. Its defect is that the solenoid valve of the spiral tube consumes a lot of power, which is very unfavorable especially for electronic sphygmomanometers using dry batteries, and at the same time, it will also have a certain impact on environmental pollution. And because the total volume of the air pump and the solenoid valve is too large, it cannot be used...
