Embodiment 1

[0026] like Figure 1-3 As shown, an intelligent breathing filtering device provided by the present invention includes: a mask 101, an air purification mechanism, an exhaust mechanism and a controller, the mask 101 is close to the user's face, and the mask 101 is provided with an air inlet and an exhaust port. The air purification mechanism is in communication with the air inlet of the mask 101; the exhaust mechanism includes a valve seat 102, an annular pressure sensor 103, a valve core 104, a valve plug 105, a vent pipe 106 and a valve cover 107, the valve seat 102 is connected to the exhaust port of the mask 101, the valve seat 102 is provided with a stepped through hole 108, the small hole end of the stepped through hole 108 is communicated with the exhaust port of the mask 101, and one end of the annular pressure sensor 103 is connected to the stepped through hole 108. On the stepped surface in the hole 108, the annular pressure sensor 103 is used to detect the pressure e...

Embodiment 2

[0031] On the basis of Embodiment 1, in order to increase the air tightness of the exhaust mechanism and improve the detection accuracy of the annular pressure sensor 103 .

[0032] likefigure 1 and 4 As shown, wherein, a sealing rubber ring 2 is also provided between the valve core 104 and the annular pressure sensor 103, and the outer side wall of the sealing rubber ring 2 is sealed with the inner wall of the large hole end of the valve seat 102. The sealing rubber One end of the ring 2 is in close contact with the annular pressure sensor 103 , and the other end of the sealing rubber ring 2 is in close contact with the valve core 104 .

[0033] By setting the sealing rubber ring 2 between the valve core 104 and the annular pressure sensor 103, when the user inhales, at the beginning, under the action of the air pressure, the valve core 104 squeezes the sealing rubber ring 2, and the sealing rubber ring 2 and the The inner wall of the large hole end of the valve seat 102 is ...

Embodiment 3

[0035] On the basis of Embodiment 2, in order to further increase the air tightness of the exhaust mechanism, air leakage of the exhaust mechanism is prevented.

[0036] like figure 1 and 4 As shown, there are multiple rings of annular teeth 3 at one end of the valve core 104 in close contact with the sealing rubber ring 2 , and each ring of the annular teeth 3 is in close contact with the end surface of the sealing rubber ring 2 .

[0037] When the user inhales, at the beginning, under the action of air pressure, the valve core 104 squeezes the sealing rubber ring 2 , and the multiple rings of annular teeth 3 on the end face of the valve core 104 are embedded in the sealing rubber ring 2 . By arranging multiple rings of annular teeth 3, the contact area between the valve core 104 and the sealing rubber ring 2 is increased, thereby increasing the air tightness of the exhaust mechanism and effectively preventing air leakage of the exhaust mechanism.

Abstract

The invention discloses an intelligent breathing filter device, which belongs to the technical field of medical protection equipment. This kind of intelligent breathing filtering device comprises: mask, close to user's face, and mask is provided with air inlet and exhaust port; Air purification mechanism, communicates with the air inlet of mask; Pressure sensor, valve core, valve plug, breather pipe and valve cover, the valve seat is connected to the exhaust port of the mask, the valve seat has a stepped through hole, the valve core has a tapered hole, the breather pipe has special-shaped holes, special-shaped holes There is a gap between the valve plug and the side wall, and a spring is provided in the special-shaped hole; the controller has a preset pressure value, and when the real-time pressure value is higher than the preset pressure value. An intelligent breathing filter device of the present invention can not only provide clean air for the user, but also ensure consistent air pressure inside and outside the mask through active air supply, so that the user will not feel strenuous when inhaling, thereby ensuring that the user Breathe easy.

Description

technical field [0001] The invention relates to the technical field of medical protection equipment, in particular to an intelligent breathing filtering device. Background technique [0002] Nowadays, people are paying more and more attention to the problem of environmental pollution. In many large and medium-sized cities in my country, the air pollution problem is very serious, and the proportion of haze weather is increasing year by year. Therefore, when people travel daily, they often wear masks to filter the air to ensure that the air they inhale is clean. [0003] The existing breathing filter device cannot actively supply air to the inside of the mask in a timely manner when the air volume inside the mask is reduced when the user inhales, which makes the user feel laborious when inhaling, resulting in poor breathing. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the problems in the prior art and provide an intelligent breathin...
