Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrators, and particularly relates to an oxygen concentrator. Background Art

[0002] Oxygen concentrators physically separate oxygen from other components in the air. They utilize a removable, integrated molecular sieve with integrated valves on the inlet and outlet pipes, providing high-purity oxygen. As living standards improve, self-driving tours are on the rise. When traveling to higher altitudes, carrying a small car-mounted oxygen concentrator is a common way to cope with altitude sickness.

[0003] In the prior art, the concentrator's connecting pipe's nozzle is located outside the concentrator housing, while the base of the connecting pipe is bolted to the interior of the concentrator housing. This type of concentrator fails to protect the connecting pipe. During use and storage in a vehicle, the concentrator can be easily damaged by movement during driving due to factors such as bumps, turns, and sudden braking, affecting normal operation. When traveling through dusty areas, the concentrator's exposed connecting pipe can also become contaminated. If contaminated, the concentrator's connecting pipe must be disassembled and cleaned.

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figure 1 As shown, an oxygen concentrator according to one embodiment of the present invention includes a housing 1, housing a power supply battery coated with a silicone protective layer. A connecting tube 2 is threadedly connected to the housing 1. One end of the connecting tube 2 is inserted into the housing 1 and connected to the oxygen supply pipeline within the housing 1. The end of the connecting tube 2, away from the oxygen supply pipeline within the housing 1, extends outside the housing 1 and is connected to a nasal oxygen cannula to deliver oxygen to the user. The above is prior art and will not be further elaborated.

[0032] In order to protect the butt joint pipe 2 from collision damage, Figures 2 to 6 As shown, the housing 1 is provided with a first placement groove 11, into which the butt joint pipe 2 is clipped. Sliding grooves 111 are provided on the four groove walls of the first placement groove 11, into which a baffle 3 is slidably connected. A handle 33 is integrally formed on the front panel of the baffle 3. When the handle 33 is pulled upward, the handle 33 can block the first placement groove 11 and protect the butt joint pipe 2.

[0033] To secure baffle 3, a docking hole 32 is formed in baffle 3 and extends through baffle 3. A locking assembly is also provided on the front panel of housing 1 for locking baffle 3. The locking assembly includes a locking pin 4, which mates with docking hole 32 in baffle 3 and is slidably connected to housing 1.

[0034] The housing 1 has a through hole that matches the locking pin 4. The through hole in the housing 1 is connected to the sliding groove 111, and the locking pin 4 is slidably connected to the through hole in the housing 1. The end of the locking pin 4 facing away from the housing 1 has a lock cap integrally formed thereon. A spring 41 is welded to the cap of the locking pin 4, and the end of the spring 41 facing away from the cap is welded to the housing 1.

[0035] Specifically, the handle 33 is pulled upward. When the upper side wall of the baffle 3 abuts the locking pin 4, the locking pin 4 is pulled outward. The handle 33 is further pulled upward. When the upper panel of the handle 33 abuts the lower wall of the first placement groove 11, the locking pin 4 is released. The locking pin 4 can then be inserted into the docking hole 32 on the baffle 3, locking the baffle 3. The handle 33 not only facilitates pulling the baffle 3, but also aligns the locking pin 4 with the docking hole 32, allowing the locking pin 4 to be accurately inserted into the docking hole 32 on the baffle 3.

[0036] like Figure 4 、 Figure 7 and Figure 8As shown, in order to conveniently fix the baffle 3 and save effort when locking the baffle 3, a first docking surface 31 is provided on the upper end side wall of the baffle 3. The first docking surface 31 is an inclined surface, and a second docking surface 42 matching the first docking surface 31 is provided on one end surface of the locking pin 4 inserted into the sliding groove 111.

[0037] Specifically, when the handle 33 is pulled upward and the first docking surface 31 and the second docking surface 42 meet, the handle 33 is further pulled upward. The second docking surface 42 is squeezed by the first docking surface 31, causing the locking pin 4 to slide outward within the through hole of the housing 1, and the spring 41 will also elastically deform. When the upper panel of the handle 33 abuts against the lower wall of the first placement slot 11, the elastic contraction force of the spring 41 causes the locking pin 4 to be inserted into the docking hole 32, locking the baffle 3. This allows for quick operation without the need to pull the locking pin 4 when closing the first placement slot 11. When in use, simply pull the locking pin 4 outward, and the baffle 3 will fall due to gravity, thereby opening the first placement slot 11.

[0038] It is worth noting that although the baffle 3 blocks most of the dust and can reduce the frequency of cleaning the butt joint 2, the butt joint 2 still needs to be cleaned and disinfected after long-term use.

[0039] In order to facilitate the disassembly and installation of the butt joint 2, Figure 4 、 Figure 8 and Figure 9 As shown, a second placement groove 112 is defined on the bottom wall of the first placement groove 11, and a through groove 113 and a rotation groove 114 are defined on the side walls of the second placement groove 112. Both the second placement groove 112 and the rotation groove 114 have circular cross-sections, and the through grooves 113 form a pair, communicating with the rotation groove 114. A rotation block 21 that matches the second placement groove 112 is bonded to the butt joint 2. The butt joint 2 passes through the rotation block 21, which is rotatably connected within the second placement groove 112. A stop block 22 that matches the through groove 113 is integrally formed on the cylindrical surface of the rotation block 21, and is made of elastic material.

[0040] Specifically, when installing the docking pipe 2, align the limit block 22 with the through groove 113, and press the rotating block 21 in the direction of the wall of the second placement groove 112. When one end face of the rotating block 21 is in contact with the bottom wall of the second placement groove 112, the limit block 22 is just inside the rotating groove 114. At this time, the rotating block 21 is rotated, and the limit block 22 is staggered with the through groove 113. The limit block 22 is compressed and contracted, and the friction between the limit block 22 and the wall of the rotating groove 114 can fix the rotating block 21 in the rotating groove 114.

[0041] Specifically, the limiting block 22 is in a convex shape, so that the end of the limiting block 22 away from the rotating block 21 can be compressed and retracted.

[0042] Furthermore, a limiting groove 115 is opened on the side wall of the rotating groove 114. When the rotating block 21 is rotated, when the limiting block 22 rotates to the position of the limiting groove 115, the limiting block 22 rebounds and is engaged in the limiting groove 115, which can make the rotating block 21 more stable in the rotating groove 114.

[0043] It is worth noting that because the limit block 22 is engaged with the limit groove 115, when removing the butt joint 2, it is necessary to rotate the rotating block 21 with great force. The cylindrical rotating block 21 and the butt joint 2 are not easy to exert force. A reinforcement block 23 is integrally formed on the front end surface of the rotating block 21, and the reinforcement block 23 matches the limit block 22. The reinforcement blocks 23 are a pair, and the pair of reinforcement blocks 23 is connected to the butt joint 2.

[0044] Specifically, holding the reinforcing block 23 and rotating the rotating block 21 can exert force. Because the reinforcing block 23 matches the limiting block 22, when the reinforcing block 23 is held and exerted, the reinforcing block 23 can directly transmit the force to the limiting block 22, which can help to rotate the limiting block 22 out of the limiting groove 115. When the reinforcing block 23 is parallel to the through groove 113, the docking tube 2 can be pulled out of the first placement groove 11. The reinforcing block 23 also serves as an indicator. At the same time, the pair of reinforcing blocks 23 are symmetrically arranged on the rotating block 21 and connected to the docking tube 2, providing support for the docking tube 2, strengthening the docking tube 2, and preventing the docking tube 2 from bending under force during cleaning.

[0045] During use, the locking pin 4 is pulled outward, and the baffle 3 falls due to gravity, opening the first placement slot 11. After use, the handle 33 is pulled upward. When the upper panel of the handle 33 abuts the lower slot wall of the first placement slot 11, the locking pin 4 is aligned with the docking hole 32. Under the elastic contraction force of the spring 41, the locking pin 4 is inserted into the docking hole 32, locking the baffle 3.

[0046] When cleaning the butt joint pipe 2, hold the reinforcing block 23 and rotate the rotating block 21. When the reinforcing block 23 is parallel to the through slot 113, the butt joint pipe 2 can be pulled out of the first placement slot 11. After cleaning, align the limit block 22 with the through slot 113, press the rotating block 21 toward the wall of the second placement slot 112, hold the reinforcing block 23 and rotate the rotating block 21. When the limit block 22 rotates to the position of the limit slot 115, the limit block 22 rebounds and engages in the limit slot 115, which can fix the rotating block 21 in the rotation slot 114.
