Abstract
The utility model discloses an air channel control valve of a miniature oxygenerator. The air channel control valve of the miniature oxygenerator comprises a system upper cover which matches with the miniature oxygenerator. A shell body is connected with the upper portion of the system upper cover. An air exchanging piece is fixed between the shell body and the system upper cover. The air exchanging piece is provided with an air exchanging hole which is communicated with the lower portion of the system upper cover. The shell body is provided with an inner cavity and an air outlet. A rotating body is simultaneously arranged in the inner cavity. A communicating groove is arranged in the lower portion of the rotating body and communicated with the inner cavity. The communicating groove matches with the air exchanging hole. The rotating body is connected with a motor. After the air channel control valve of the miniature oxygenerator is optimized, the motor is arranged at the upper portion of the shell body, a compressed spring is arranged between the rotating body and the motor, the compressed spring downward extrudes the rotating body through a bearing, a rotation shaft of the motor is provided with an oil seal and a sealing washer is arranged between the air exchanging piece and the shell body. The air channel control valve of the miniature oxygenerator has the advantages of being free from complicated assembly when the air channel control valve of the miniature oxygenerator is used and not prone to leak air.
Description
Technical field
The present invention relates to the oxygenerator technical field, especially relate to a kind of gas path control valve of Miniature oxygenerator.
Background technique
At present, the rotary valve that Miniature oxygenerator is commonly used is formed by a plurality of component combinations, all parts need to be assembled respectively during use, is easy to gas leakage during comparatively complexity, and use.
Summary of the invention
The gas path control valve that the purpose of this invention is to provide a kind of Miniature oxygenerator, it has the advantages that to need not to carry out complicated assembling when using.Further, it has the advantages that to be difficult for gas leakage when using.
The technical solution adopted in the present invention is: the gas path control valve of Miniature oxygenerator, the gas path control valve of described Miniature oxygenerator comprises the system's upper cover that matches with Miniature oxygenerator, this system's upper cover top is connected with housing, be fixed with the ventilation sheet between this housing and system's upper cover, this ventilation sheet has the air-vent of connected system upper cover bottom, this housing has inner chamber and relief opening, simultaneously, be provided with solid of rotation in this inner chamber, the bottom of this solid of rotation is provided with the connectivity slot of communication with cavity, and this connectivity slot and air-vent match, and this solid of rotation is connected with motor.
Described motor is positioned at the top of housing, and is provided with stage clip between solid of rotation and motor, and this stage clip pushes this solid of rotation downwards by bearing.
The running shaft of described motor is provided with oil sealing.
Be provided with seal washer between described ventilation sheet and housing.
The advantage that compared to the prior art the present invention has is: need not to carry out complicated assembling when 1, using.The gas path control valve used unit of Miniature oxygenerator of the present invention is less, and all is integrated in system and covers.During use, only need system's upper cover is connected with this Miniature oxygenerator to get final product, need not to carry out the assembling of all parts, very convenient.Be difficult for gas leakage when 2, using.Solid of rotation can be pressed under the effect of stage clip on the ventilation sheet, and each key position is equipped with seal arrangement, the gas leakage probability when these measures all effectively reduce use.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of embodiments of the invention looks sectional view (part).
In figure: 10, system's upper cover; 20, housing, 21, inner chamber, 22, relief opening; 30, ventilation sheet, 31, air-vent, 32, seal washer; 40, solid of rotation, 41, connectivity slot; 50, bearing, 60, stage clip; 70, oil sealing; 80, motor.
Embodiment
Embodiment, as shown in Figure 1: the gas path control valve of Miniature oxygenerator, comprise the system's upper cover 10 that matches with Miniature oxygenerator, this system's upper cover 10 tops are connected with housing 20.Be fixed with ventilation sheet 30 between this housing 20 and system's upper cover 10, this ventilation sheet 30 has the air-vent 31 of connected system upper cover 10 bottoms, and this housing 20 has inner chamber 21 and relief opening 22.That is, only when air-vent 31 and inner chamber 21 connection, the prepared oxygen of Miniature oxygenerator can finally be discharged from this relief opening 22 via this inner chamber 21 by this air-vent 31.Simultaneously, be provided with solid of rotation 40 in this inner chamber 21, the bottom of this solid of rotation 40 is provided with the connectivity slot 41 of communication with cavity 21, and this connectivity slot 41 and air-vent 31 match, and this solid of rotation 40 is connected with motor 80.That is, after motor 80 driven rotary body 40 rotations, in a single day connectivity slot 41 aims at air-vent 31, even inner chamber 21 and air-vent 31 are communicated with, realizes the discharge of the prepared oxygen of Miniature oxygenerator.Like this, the gas path control valve used unit of this Miniature oxygenerator is less, and all is integrated on system's upper cover 10, only needs during use system's upper cover 10 is connected with this Miniature oxygenerator to get final product, and is very convenient.
Optimize, this motor 80 is positioned at the top of housing 20, and is provided with stage clip 60 between solid of rotation 40 and motor 80, and this stage clip 60 pushes this solid of rotation 40 downwards by bearing 50.That is, solid of rotation 40 is comparatively tight with contacting of ventilation sheet 30, is difficult for the phenomenon that leaks air.
Further, the running shaft of this motor 80 is provided with oil sealing 70, is provided with seal washer 32 between this ventilation sheet 30 and housing 20.Like this, in the joint of the motor 80 that is easy to leak gas and housing 20 and the joint of ventilation sheet 30 and housing 20 all carried out encapsulation process, the probability that the gas path control valve of Miniature oxygenerator of the present invention leaks air is further reduced.
The above is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
