DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: This embodiment is intended to promote the solution of the problem that most of the regulating valves of existing oxygen concentrators rely on turning the knob to drive the valve core 200 to move up and down to adjust the size of the valve switch, thereby controlling the size of the flow. However, this adjustment method may cause the flow control to be not accurate enough, resulting in the problem that the user's needs cannot be met. Please refer to Figure 1-Figure 4 A flow regulating valve for an oxygen concentrator comprises a valve housing 100, a valve core 200, an oxygen outlet pipe 300 and an oxygen inlet pipe 400. The valve core 200 is arranged in the valve housing 100. An oxygen outlet housing 110 is fixedly plugged into the valve housing 100. The oxygen outlet pipe 300 is threadedly installed at the top of the oxygen outlet housing 110. The valve core 200 is plugged into the oxygen outlet housing 110. A mounting hole 120 is provided at the bottom of the valve housing 100. The oxygen inlet pipe 400 is plugged into the mounting hole 120. An oxygen passing space 210 is provided in the valve core 200. The top of the oxygen inlet pipe 400 is plugged into the bottom of the valve core 200. A valve ball 220 is fixedly installed on the top of the valve core 200. A plurality of regulating holes 221 are provided in the valve ball 220. The regulating holes 221 are communicated with the oxygen passing space 210. A control component 500 for controlling the valve core 200 is provided in the valve housing 100.

[0023] A ball 130 is arranged in the oxygen outlet pipe 300, and the ball 130 is arranged in three groups. The number of the three groups of balls 130 corresponds to the number of the adjustment holes 221. The three groups of balls 130 are divided into group A 131, group B 132 and group C 133. The diameter of the ball 130 in group A 131 is larger than the diameter of the ball 130 in group B 132, the diameter of the ball 130 in group B 132 is larger than the diameter of the ball 130 in group C 133, and the diameter of the ball 130 in group A 131 corresponds to the diameter of the adjustment hole 221.

[0024] A retraction groove 140 for retracting the ball 130 is provided in the valve housing 100, a telescopic rod 141 is provided in the retraction groove 140, a spring 142 is provided on the outer sleeve of the telescopic rod 141, one end of the spring 142 is fixedly connected to the ball 130, and the other end of the spring 142 is fixedly connected to the inner wall of the retraction groove 140. The control assembly 500 includes a control rod 510 inserted in the valve housing 100, the control rod 510 is located at the side of the oxygen outlet housing 110, a driving gear 520 is fixedly provided on the outer sleeve of the control rod 510, the driving gear 520 is located in the valve housing 100, and a driving gear 530 is provided on the outer sleeve of the valve core 200, and the driving gear 520 is meshed with the driving gear 530.

[0025] A control knob 540 is installed at the top of the control rod 510, and an adjustment scale 541 is arranged outside the control knob 540, and the adjustment scale 541 is set to three. A control ring 550 for locking the control assembly 500 is fixedly installed outside the control rod 510, and a locking strip 551 is installed outside the control ring 550. A locking groove 552 corresponding to the locking strip 551 is opened in the valve housing 100, and the locking groove 552 is arranged to three, and the three locking grooves 552 correspond to the three adjustment scales 541.

[0026] When the oxygen flow rate needs to be adjusted to a smaller value, the control knob 540 is turned clockwise to drive the control rod 510 to rotate. As the control rod 510 rotates, the driving wheel drives the gear 530 to rotate, and then the valve core 200 is driven to rotate. At this time, the ball 130 of the C group 133 originally located in the adjustment hole 221 will be separated from the adjustment hole 221 and retracted into the retraction groove 140 as the valve ball 220 rotates. At the same time, as the valve ball 220 rotates, the ball 130 of the B group 132 will be released from the retraction groove 140 and enter the adjustment groove. Since the diameter of the ball 130 of the B group 132 is larger than that of the ball 130 of the C group 133, when the ball 130 of the B group 132 enters the adjustment hole 221, the oxygen output from the adjustment hole 221 on the valve ball 220 will decrease. When the ball 130 of group B 132 reaches the adjustment hole 221, the second adjustment scale 541 on the control knob 540 will face upward, and the locking bar 551 on the control rod 510 will correspond to the second locking groove 552. At this time, press the control knob 540 downward to push the control rod 510, so that the locking bar 551 engages with the second locking groove 552, thereby completing the adjustment.

[0027] When the oxygen needs to be completely shut off, the control knob 540 is pulled to pull the control rod 510, so that the locking groove 552 originally in the second locking groove 552 is unlocked, and then the knob is turned clockwise again, so that the ball 130 of the B group 132 is disengaged from the adjustment hole 221, and the ball 130 of the A group 131 is in conflict with the adjustment hole 221. Since the diameter of the ball 130 of the A group 131 corresponds to the diameter of the adjustment hole 221, the ball 130 of the A group 131 will block the adjustment hole 221, so that the oxygen cannot be output. When the ball 130 of the A group 131 reaches the adjustment hole 221, the first adjustment scale 541 on the control knob 540 will face upward, and the locking bar 551 on the control rod 510 will correspond to the first locking groove 552. At this time, the control knob 540 is pressed downward to push the control rod 510, so that the locking bar 551 is engaged with the first locking groove 552, thereby completing the shutoff of the oxygen.

[0028] Similarly, when the oxygen flow rate needs to be increased, it is only necessary to pull out the control knob 540 according to the above instructions to unlock the locking bar 551, and then turn the control knob 540 counterclockwise.

[0029] In this embodiment: by controlling the position of the valve core 200 and the movement of the ball 130, the oxygen output flow rate can be accurately adjusted to ensure that the patient obtains the required oxygen supply. By using the control knob 540 and the adjustment scale 541, the user can easily adjust the oxygen flow rate, and the design of the locking bar 551 makes it possible to fix the required flow rate, which is more convenient to operate. The locking groove 552 and the locking bar 551 can avoid abnormal oxygen flow caused by misoperation, thereby improving the safety of the equipment.

[0030] Embodiment 2: This embodiment is intended to promote the solution of the sealing of the connection between the oxygen inlet pipe 400 and the valve housing 100, and the oxygen may leak. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 4 .

[0031] An annular clamping block 230 is installed at the bottom of the valve core 200, and an annular clamping groove 310 corresponding to the annular clamping block 230 is provided in the oxygen inlet pipe 400, and the annular clamping block 230 is clamped with the annular clamping groove 310. An external threaded ring 320 is provided outside the oxygen inlet pipe 400, and an internal threaded ring 121 corresponding to the external threaded ring 320 is provided in the mounting hole 120, and the internal threaded ring 121 is threadedly connected with the external threaded ring 320, and a sealing film 122 is provided between the internal threaded ring 121 and the external threaded ring 320, and the sealing film 122 is set as a rubber film. The annular clamping block 230 is installed at the bottom of the valve core 200, and a corresponding annular clamping groove 310 is provided in the oxygen inlet pipe 400. Through the clamping of the annular clamping block 230 and the annular clamping groove 310, it can be ensured that the connection between the valve core 200 and the valve housing 100 is more stable, and the displacement or instability of the position of the valve core 200 is avoided, thereby improving the accuracy of oxygen flow regulation.

[0032] In this embodiment, an external threaded ring 320 is provided on the outside of the oxygen inlet pipe 400, and a corresponding internal threaded ring 121 is provided in the mounting hole 120, and a sealing film 122, such as a rubber film, is provided between the two, so that the connection between the oxygen inlet pipe 400 and the valve housing 100 can be ensured to have good sealing performance, thereby preventing oxygen leakage, thereby improving the reliability and safety of the oxygen flow regulating valve.
