Description

Technical Field

[0001] This utility model belongs to the field of oxygen valve technology, specifically, it relates to an oxygen valve assembly. Background Technology

[0002] An oxygen valve is a valve device specifically designed to control the flow of oxygen, and it is widely used in physical and chemical experiments, industrial production, medical fields, and other areas.

[0003] Among them, multi-channel oxygen valves can control the oxygen flow path during use, and valves are installed in each channel to control the opening and closing of the path. Most existing valves control the opening or closing of the path by rotating a knob. In order to make it easy to see whether the path is open or closed, indicator arrows or other markings that can indicate the valve status are usually set on the knob. However, some users are often confused by the markings, making it difficult to clearly know whether the path is open or closed. This is especially true when the oxygen valve is used in medical equipment such as oxygen concentrators, where the users are middle-aged or elderly people, who find it difficult to understand whether the path is open or closed. Therefore, an oxygen valve component is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an oxygen valve assembly that can overcome or at least partially solve the above problems.

[0006] Preferably, a limiting block is fixedly connected to the bottom surface of the knob, and a limiting groove is formed on the end face of the valve tube to limit the rotation angle of the valve core.

[0007] Preferably, the valve core is provided with a locking block to limit the valve core in the length direction.

[0008] Furthermore, the top surface of the knob has a mounting groove, the mounting groove has a battery compartment, the battery compartment has a battery installed, and a first mounting block is fixedly connected to the outer surface of the knob. The first mounting block has two contacts installed on it. A second mounting block is installed on the outer wall of the valve tube, and an electrode is installed on the second mounting block. When the knob is rotated, the two contacts come into contact with the electrode, and the LED light up.

[0010] Furthermore, a plug is fixedly connected to the compartment cover.

[0011] Furthermore, symmetrical insertion holes are provided on the top surface of the knob, and one end of the insertion rod corresponds to the insertion hole.

[0012] Furthermore, a groove is formed on the outer wall surface of the knob.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Example 1: Refer to Figures 1-7 An oxygen valve assembly includes a valve body 1 having a first passage 11, a second passage 12, and a third passage 13, and further includes: valve tubes 15 respectively disposed on the second passage 12 and the third passage 13, a valve core 141 rotatably disposed in the valve tube 15, the valve core 141 having a through-hole 143 corresponding to the passage in the second passage 12 and the third passage 13; a knob 14 fixedly connected to one end of the valve core 141; and an LED 17 disposed on the knob 14, which rotates the knob 14 to drive the valve core 141 to rotate. When the passage is open, the LED 17 emits light, and when the passage is closed, the LED 17 does not emit light.

[0026] A limit block 140 is fixedly connected to the bottom surface of the knob 14, and a limit groove 151 is opened on the end face of the valve tube 15 to limit the rotation angle of the valve core 141.

[0027] A locking block 142 is provided on the valve core 141 to limit the valve core 141 in the length direction.

[0028] The top surface of the knob 14 has a mounting groove 16, in which a battery compartment 161 is provided, and a battery is installed in the battery compartment 161. A first mounting block 144 is fixedly connected to the outer surface of the knob 14, and two contacts 145 are installed on the first mounting block 144. A second mounting block 18 is installed on the outer wall of the valve tube 15, and an electrode 181 is installed on the second mounting block 18. When the knob 14 is rotated, the two contacts 145 contact the electrode 181, and the LED bead 17 lights up.

[0029] When in use, if it is necessary to open the second passage 12 or the third passage 13, simply rotate the corresponding knob 14 to drive the valve core 141 to rotate, so that the opening 143 is connected to the passage, thereby opening the passage.

[0030] When the channel is not open, the contact 145 and the electrode 181 are offset. When the channel is open, the valve core 141 rotates 90 degrees and both contacts 145 are in contact with the electrode 181. At this time, the circuit is connected and the lamp 17 lights up to indicate that the oxygen channel is open.

[0031] Furthermore, the color of the LED bead 17 can be rotated according to actual production needs. In this embodiment, the preferred light-emitting color of the LED bead 17 is green.

[0032] In one embodiment, when the circuit is on, the LED 17 can emit light continuously, which can better serve as a prompt.

[0033] In another embodiment, when the circuit is connected, the LED 17 emits light for a certain duration, which can be set according to actual production needs. When the light emission time is temporary, battery power can be saved.

[0034] In one embodiment, the battery is a button cell.

[0035] In another embodiment, the battery can be of other shapes, as long as it is large enough to fit into the battery compartment 161.

[0036] In another embodiment, the battery selection can be set according to actual needs, and users can also modify it themselves, but please pay attention to safety when modifying it.

[0037] Therefore, this device uses LED beads 17 that can emit light as an indicator to clearly show whether the channel is open, and makes it easier to use the adjustment knob 14.

[0038] Example 2: Refer to Figures 1-3 An oxygen valve assembly is basically the same as in Embodiment 1, but further: a cover 162 is engaged in the mounting groove 16. The cover 162 is used to cover the mounting groove 16 and restrict the battery in the battery compartment 161 to prevent the battery from falling out.

[0039] The cover 162 is connected to the mounting slot 16 by a snap-fit ​​connection, which makes it easy to open the cover 162.

[0040] A gap is left between the side of the cover 162 near the top surface of the knob 14 and the top surface of the knob 14, so that a fingernail or object can enter the gap between the cover 162 and the knob 14 to open the cover 162.

[0041] Example 3: Reference Figure 1 An oxygen valve assembly, which is basically the same as in Embodiment 2, but further: a plug rod 163 is fixedly connected to the cover 162;

[0042] The top surface of the knob 14 has symmetrically arranged insertion holes 164, and one end of the insertion rod 163 corresponds to the insertion hole 164;

[0043] The insertion rod 163 is connected to the compartment cover 162, which allows the compartment cover 162 to be easily detached from the mounting slot 16;

[0044] After the insertion rod 163 enters the insertion hole 164, it can be used to assist the rotation of the knob 14, thus facilitating the rotation of the knob 14.

[0045] A groove 146 is provided on the outer wall surface of the knob 14. The groove 146 can increase the friction between the finger and the knob 14, thereby making it easier to rotate the knob 14.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
