Description

Technical Field

[0001] The utility model relates to the technical field of gas control, and particularly relates to a control device for an oxygen diffusion terminal. Background Art

[0002] With the aggravation of social aging and the improvement of the living and living environment with hypoxia in high-altitude areas, more and more people have an increasing demand for indoor oxygen enrichment. At present, the main method for indoor oxygen distribution is to control the oxygen delivery through a host, and the oxygen delivery is often controlled by integrating a solenoid valve inside to open and close the oxygen pipeline. This control method has obvious control defects in use.

[0003] The working principle of solenoid valve control is that the electromagnetic force generated by the internal coil separates the valve stem from the base to conduct. During this action process, there is often obvious noise, and the greater the gas, the stronger the noise. Moreover, during the use of the solenoid valve, the action is relatively single (i.e., opening or closing), and the size of the opened channel cannot be controlled. Due to its sealing method, the bottom surface of the valve stem contacts the upper plane of the base for sealing. If there are impurities in the gas, it will affect the sealing performance of the contact surface, resulting in the problem of poor sealing. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problems in the prior art, and provide a control device for an oxygen diffusion terminal, which can shunt the oxygen supplied by the oxygen supply device, synchronously adjust the oxygen flow rates of multiple shunts, and can achieve fine control of the oxygen flow rates of multiple shunts gently, and reduce the ventilation noise.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0022] As Figure 1 and Figure 2 shown, the control device of the oxygen diffusion terminal provided by the present utility model includes: a control valve body 101 and a synchronous regulating valve rod 107. The control valve body 101 is provided with an air inlet 102, an air inlet passage 103, a shunt passage 104 and a plurality of air outlets 105. The air inlet 102 is communicated with an oxygen supply device, the air inlet 102 is communicated with the air inlet passage 103, the shunt passage 104 is communicated with the air inlet passage 103, the plurality of air outlets 105 are all communicated with the shunt passage 104, a first valve hole 106 is provided between the air inlet passage 103 and the shunt passage 104, an internal thread is provided in the first valve hole 106, and the first valve hole 106 is communicated between the air inlet passage 103 and the shunt passage 104; the synchronous regulating valve rod 107 is threadedly connected with the first valve hole 106, one end of the valve rod protrudes from the control valve body 101, and the other end of the synchronous regulating valve rod 107 is inserted between the air inlet passage 103 and the shunt passage 104. Rotating the synchronous regulating valve rod 107 can adjust the communication degree between the air inlet passage 103 and the shunt passage 104.

[0023] Now briefly describe the working principle of the above embodiments:

[0024] The oxygen supplied by the oxygen supply device enters the valve body through the air inlet 102. Rotate the synchronous regulating valve rod 107 to connect the air inlet passage 103 with the shunt passage 104. The oxygen enters the shunt passage 104 through the air inlet passage 103 and then flows out through a plurality of air outlet ports 105 connected to the shunt passage 104, so as to supply oxygen to different rooms. During this process, by rotating the synchronous regulating valve rod 107, the connection degree between the air inlet passage 103 and the shunt passage 104 is adjusted, so that the flow rate of the oxygen flowing out of the plurality of air outlet ports 105 can be synchronously controlled, and the oxygen supply speed of each room can be synchronously controlled.

[0025] The control device of the oxygen diffusion terminal of the present utility model can shunt the oxygen supplied by the oxygen supply device, synchronously adjust the flow rates of a plurality of shunted oxygen, and can achieve fine control of the flow rates of the plurality of shunted oxygen, so as to reduce the ventilation noise.

[0026] On the basis of the above embodiments, in order to improve the sealing performance of the valve rod to the air inlet passage 103.

[0027] As Figure 1 and Figure 2 shown, one end of the first valve hole 106 is provided with a tapered hole 201.

When the other end of the synchronous regulating valve rod 107 is rotated, the side wall of the tapered valve core 202 can be attached to the side wall of the tapered hole 201.

[0028] By providing the tapered hole 201 and the tapered valve core 202, the oxygen supplied by the oxygen supply device enters the first valve hole 106 through the air inlet passage 103, and then enters the shunt passage 104 through the tapered hole 201. When the synchronous regulating valve rod 107 is rotated, under the action of the internal thread of the synchronous regulating valve rod 107 in the first valve hole 106, the tapered valve core 202 can be driven to approach or move away from the tapered hole 201, so as to adjust the gap between the tapered hole 201 and the tapered valve core 202, and thus adjust the connection degree between the air inlet passage 103 and the shunt passage 104. Moreover, when the air inlet passage 103 is closed, the synchronous regulating valve rod 107 can drive the outer wall of the tapered valve core 202 to be tightly attached to the tapered hole 201, so as to improve the sealing performance of the valve rod to the air inlet passage 103.

By providing the power device 402, the power device 402 is controlled by the controller to act, so as to drive the adjusting knob 3 to rotate, which can not only improve the automation degree of the whole control device, but also further accurately control the connection degree between the air inlet passage 103 and the shunt passage 104.

[0031] As a preferred solution, as Figure 1 and Figure 2 shown in the figure, the power device 402 is a stepping motor. Using the stepping motor as the power device 402 can further improve the accuracy of controlling the rotation angle of the synchronization regulating valve rod 107, and thus further improve the accuracy of controlling the connection degree between the air inlet passage 103 and the shunt passage 104.

[0032] As a preferred solution, as Figure 1 and Figure 2 shown in the figure, a second valve hole 501 is provided between each air outlet 105 and the shunt passage 104. The inner wall of the second valve hole 501 is provided with internal threads, and a regulating valve rod 502 is threadedly connected to the inner wall of the second valve hole 501.
