Description

Portable air infectious substance filtering device

The present invention relates to a filtering device, and more specifically, to a portable air infectious agent filtering device.

The main purpose of the conventional medical air filter device is to provide purified air to users (such as medical staff or patients). Therefore, only one air tube is equipped in the structure to introduce air into the mask. That is to say, the conventional medical air filter device does not perform any filtering treatment on the gas exhaled by users (such as medical staff or patients), but allows it to be dispersed into the air. However, when a user (such as a medical staff or patient) is in an unhealthy state (for example, infected with pneumonia or other respiratory diseases), the gas exhaled may carry viruses or bacteria, which may cause infection to others.

Therefore, it is necessary to improve the conventional medical air filter device to solve the above-mentioned problems.

In one embodiment, a portable air infection filtering device includes a mask, a housing, at least one air infection filtering element, an air suction element, an air introduction tube and an air outlet tube. The shell has a plurality of air holes and an internal space. The air holes are arranged at intervals. The internal space defines an inlet chamber and an outlet chamber. The air inlet chamber and the air outlet chamber correspond to the air holes. The air infection filter element is arranged between the air hole and the air inlet chamber and the air outlet chamber. The air suction member is arranged in the air inlet chamber. The air introduction pipe connects the air suction member and the mask. The air outlet pipe connects the mask and the air outlet chamber.

In one embodiment, a portable air infection filter device includes a mask, a housing, at least one air infection filter, an air introduction tube, and an air outlet tube. The shell has a plurality of air holes and an internal space. The air holes are arranged at intervals. The internal space defines an inlet chamber and an outlet chamber. The air inlet chamber and the air outlet chamber correspond to the air holes. The air infection filter element is arranged between the air hole and the air inlet chamber and the air outlet chamber. The air introduction pipe connects the air inlet chamber and the mask. The air outlet pipe connects the mask and the air outlet chamber.

With reference to Figures 1 to 4, the portable air infection filter device 1 of the present invention includes a mask 10, a housing 20, at least one air infection filter 30, an air suction member 40, and an air introduction tube 50 , An air outlet pipe 60, a power supply 70 and a control circuit unit 80. In one embodiment, the infectious agent is a virus or bacteria.

The mask 10 can be used to cover the nose and mouth of a user 9. In one embodiment, the mask 10 may be a helmet-type mask to cover the entire head of the user 9.

The casing 20 has a top wall 201, a side wall 202, a plurality of air holes 21, an internal space 22, at least one slot 23 and a card slot 24. The air holes 21 penetrate through the side wall 202, and the air holes 21 are arranged at intervals. The internal space 22 defines an air inlet chamber 221, an air outlet chamber 222 and a receiving groove 223. The air inlet chamber 221 and the air outlet chamber 222 correspond to the air hole 21, and the air inlet chamber 221 and the air outlet chamber 222 are not connected to each other. In one embodiment, the volume of the inlet chamber 221 is greater than the volume of the outlet chamber 222. The accommodating groove 223 is opposite to the air inlet chamber 221.

The slot 23 is recessed in the top wall 201, and the slot 23 is located between the air hole 21 and the air inlet chamber 221 and the air outlet chamber 222. The slot 24 is located between the air inlet chamber 221 and the receiving slot 223.

FIG. 5 shows a detailed structure diagram of the air infection filter 30 according to an embodiment of the present invention. With reference to Figures 1, 3 and 5, the air infection filter 30 is disposed between the air hole 21 and the air inlet chamber 221 and the outlet chamber 222, and the air infection filter 30 It is set in the slot 23. In an embodiment, the air-infectious substance filter 30 may be a multi-layer filter structure, and the multi-layer filter structure may include an outer layer L1, an inner layer L2, and at least one middle meltblown layer L3. The outer layer L1 may be spunbonded fabric. The inner layer L2 may be low melting point cotton. The intermediate meltblown layer L3 is disposed between the outer layer L1 and the inner layer L2, and the intermediate meltblown layer L3 itself is charged and can adsorb infectious substances (for example, viruses or bacteria).

In addition, the air infection filter 30 may be in the shape of a sawtooth plate or a wave plate to increase the adsorption area.

Referring to FIGS. 1 to 4 again, the air suction member 40 is disposed in the air inlet chamber 221 to suck in external air. The outside air enters the air intake chamber 221 and the air suction member 40 through the air hole 21 and the air infection filter 30. In one embodiment, the air suction member 40 may be an air pump or a fan.

The air introduction pipe 50 connects the air suction member 40 and the mask 10 to introduce filtered air into the mask 10 for the user 9 to breathe. In one embodiment, when the ambient pressure conditions permit, the air extraction member 40 can be omitted. At this time, the air introduction pipe 50 can connect the air inlet chamber 221 and the mask 10.

The air outlet tube 60 connects the mask 10 and the air outlet chamber 222 to export the air exhaled by the user 9 to the air outlet chamber 222, and after being filtered by the air infection filter 30, it passes The air hole 21 is discharged to the outside of the housing 20. Since the infectious substance in the air exhaled by the user 9 has been filtered out by the air infectious substance filter 30, the discharged air will no longer cause infection to others. In one embodiment, a one-way valve can be provided at the connection between the air outlet pipe 60 and the air outlet chamber 222 to prevent gas from flowing back.

In addition, in order to accelerate the expulsion of the air exhaled by the user 9, the diameter of the air outlet tube 60 is larger than the diameter of the air inlet tube 50, so as to reduce the air discharge resistance.

The power supply unit 70 is disposed in the slot 24 of the housing 20, and the power supply unit 70 can be plugged and replaced. The control circuit unit 80 is disposed in the accommodating groove 223, and the control circuit unit 80 is electrically connected to the power supply member 70 and the air suction member 40. Therefore, the power required by the control circuit unit 80 can be provided by the power supply unit 70, and the action of the air suction unit 40 (for example, air output pressure adjustment) can be controlled by the control circuit unit 80.

In an embodiment, the air extraction direction of the air extraction member 40 may include a forward direction and a reverse direction. The forward direction is the air outlet direction toward the air introduction pipe 50 (as shown in FIG. 4), and the reverse The air outlet direction is toward the air infection filter 30. Regardless of whether the suction direction of the suction member 40 is the forward direction or the reverse direction, the same filtering effect can be achieved.
