Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
Fig. 1 shows according to respirator 100 of the present utility model.As shown in Figure 1, respirator 100 comprises respirator main body 1, humidifier, and humidifier comprises water tank 2 and anti-recirculation device 3.As shown in Figure 2, respirator main body 1 is provided with exhaustor 4.The sidewall of water tank 2 is provided with the air intake 5 be communicated with exhaustor 4, for the gas received from respirator main body 1.Anti-recirculation device 3 is arranged in the inner chamber of water tank 2, and is communicated with air intake 5, with receiver gases, and for preventing the liquid in water tank 2 from entering in respirator main body 1.
According to an embodiment of the present utility model, the liquid collecting body 7 that anti-recirculation device 3 comprises elbow member 6 and is connected with elbow member 6.Wherein, the second segment 9 that elbow member 6 has first paragraph 8 and is communicated with first paragraph 8, and first paragraph 8 is communicated with the gas for receiving from respirator main body 1 with air intake 5.Open Side Down that end extends in the inner chamber of liquid collecting body 7 by liquid collecting body 7 for the second segment 9 of elbow member 6.Gap 10 is formed between the lateral wall of the second segment 9 of elbow member 6 and the medial wall of liquid collecting body 7.
When respirator 100 works, forced air is by the exhaustor 4 of respirator main body 1, by air intake 5, enter the first paragraph 8 of anti-recirculation device 3, entered by second segment 9 again in the inner chamber of liquid collecting body 7, entered in water tank 2 by the opening part of liquid collecting body 7 finally by gap 10, and finally supply to wearer.Occur tilting at respirator 100, rock, even the fortuitous event such as upset time, as Figure 4-8, owing to there is above-mentioned anti-recirculation device 3, make the liquid in humidifier can not enter into respirator main body 1.Thus, this respirator 100 can avoid parts in respirator main body 1 liquid or immersion, ensure the safety used, ensure the safety of user simultaneously.Meanwhile, by the respirator 100 of this structure, other can be avoided directly to blow liquid surface, thus avoid liquid fluctuating or water spray phenomenon and the user that causes is choked water accident.Thus, this respirator 100 further ensures the safety of user.
In medical instruments field, home ventilator volume is little, uses flexibly, and in use needs often carrying or transfer, and therefore above-mentioned anti-recirculation device 3 is particularly useful for home ventilator.
It should be noted that, for the ease of connecting, and ensure the compactness of connection, exhaustor 4 directly can be connected with anti-recirculation device 3 through air intake 5.
According to this utility model, as Figure 4-8, when humidifier tilts with all angles or overturns, all can ensure that the liquid in water tank 2 does not flow in respirator main body 1 by anti-recirculation device 3, liquid collecting body 7 is arranged on the middle position of the inner chamber of water tank 2.Further, in order to improve safety further, the liquid volume in water tank 2 is also preferably set to 1/3rd of the volume of the inner chamber being no more than water tank 2.
As shown in Figure 2, in order to ensure the unimpeded of pressed gas in humidifier, the port of export of second segment 9 is provided with pore 11.Preferably, pore 11 is configured to domes.The structure of above-mentioned pore 11 is simple, facilitates processing and manufacturing, and the breathing area of domes is large simultaneously, is conducive to airflow.
In one embodiment, the diapire of liquid collecting body 7 is arranged the inside and outside micropore 12 be communicated with, can be seen by Fig. 3.Micropore 12 can be one or more in circular hole, elliptical aperture, square opening, tri-angle-holed or polygonal hole.Preferably, the effective diameter of this micropore 12 is 0.1-1mm.By this set, even if the water in water tank 2 can enter into anti-recirculation device 3, under Gravitative Loads, the water remained in liquid collecting body 7 also flow back in water tank 2 again by micropore 12.Certainly, to carry or in moving process, owing to rocking, the liquid in water tank 2 likely can impact the diapire of liquid collecting body 7, and the micropore 12 of this structure can ensure that liquid can not enter liquid collecting body 7 from the inner chamber of water tank 2 at respirator 100.Thus said structure avoids water and remains in the microorganism such as breed bacteria or virus in liquid collecting body 7, ensure that the safety in utilization of respirator 100.
In order to deep layer clear up anti-recirculation device 3 further, avoid liquid residue in liquid collecting body 7, liquid collecting body 7 can be configured to detachable connection with elbow member 6.Such as, the port of export of second segment 9 is with the diapire clamping of liquid collecting body 7 or be threaded.Certainly, this utility model is not limited to this syndeton, such as, the top cover (not shown) be fixedly connected with it can also be set at the opening part of liquid collecting body 7, and top cover is provided with the through hole (not shown) of the inside and outside connection making liquid collecting body 7, second segment 9 can extend in the inner chamber of liquid collecting body 7 through top cover, and second segment 9 can adopt clamping with top cover or be threaded.Be easy to liquid collecting body 7 to remove to carry out cleaning or changing from elbow member 6 by this set.Thus, all should fall in protection domain of the present utility model as long as liquid collecting body 7 can be realized with the detachable version be connected of elbow member 6.
Meanwhile, when top cover is connected with elbow member 6, the port of export of second segment 9 must not be provided with pore 11, but make to leave certain interval between the diapire of the port of export of second segment 9 and liquid collecting body 7 and just can.In one embodiment, the diapire of liquid collecting body 7 can be configured to the arcuation of evagination, as shown in Figure 9.The liquid collecting body 7 of this structure can make upwards to flow more smooth and easy from the gas of respirator main body 1, avoids eddy current.In addition, if arrange micropore 12 at the diapire of liquid collecting body 7, then micropore 12 can be arranged on around the most convex place of the diapire of liquid collecting body 7, to help in liquid again reflow tank 2.
In another embodiment, the diapire of liquid collecting body 7 can be configured to the arcuation of convex, as shown in Figure 10.Meanwhile, the diapire of liquid collecting body 7 and sidewall junction is made to be in bottom.The diapire of liquid collecting body 7 and sidewall junction can also be provided with micropore 12.Thus, the liquid entered in liquid collecting body 7 due to fortuitous event can flow out liquid collecting body 7 easily.
In the application, orientation term " on ", D score with the real work position of respirator 100 for reference.
The foregoing is only preferred implementation of the present utility model; but this utility model protection domain is not limited thereto; any those skilled in the art is in technical scope disclosed in this utility model; can easily carry out changing or changing, and this change or change all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
