Description

Technical Field

[0001] This utility model relates to the field of oxygen generators, and in particular to a connector for connecting a compressor and a valve body. Background Technology

[0002] Portable oxygen concentrators are small devices designed for users who need oxygen therapy. With their portability, ease of use, and stability, they provide great convenience to users, especially those who need long-term oxygen therapy or outdoor activities, and can significantly improve their quality of life.

[0003] In existing portable oxygen concentrators, the compressor outlet and the two-position five-way valve of the separator are mainly connected by a silicone hose. This connection method has the following disadvantages:

[0004] 1. Silicone hoses have poor assembly properties, and the length of silicone hoses used is often longer than the theoretical size of the two-position five-way valve from the compressor outlet to the separator, resulting in silicone hoses taking up a large amount of extra space inside the portable oxygen concentrator.

[0005] 2. During the operation of the oxygen concentrator, the silicone hose is prone to detachment, causing gas leakage, and is also prone to bursting.

[0006] 3. Silicone hoses have poor noise reduction effect. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a connector for connecting a compressor and a valve body.

[0008] According to one aspect of the present invention, a connector for connecting a compressor and a valve body is provided, comprising a housing made of rigid plastic, an air passage provided in the housing, an inlet pipe provided at one end of the housing, an outlet pipe provided at the other end of the housing, both the inlet pipe and the outlet pipe communicating with the air passage, both the inlet pipe and the outlet pipe being located on the same side of the housing, and both the housing and the air passage being in a zigzag shape.

[0009] The connector of this utility model connects the inlet pipe to the outlet of the oxygen concentrator's compressor and the outlet pipe to the two-position five-way valve of the oxygen concentrator's separator. The compressed gas generated by the oxygen concentrator's compressor enters the two-position five-way valve of the separator through the inlet pipe, the air passage in the housing, and the outlet pipe. The housing is made of rigid plastic, and the inlet and outlet pipes are located on the same side of the housing, which facilitates assembly. During operation, the oxygen concentrator can avoid problems such as pipe bursting and detachment. Moreover, because the housing is zigzag-shaped, it can effectively utilize the space between the compressor's outlet and the two-position five-way valve of the separator, without occupying additional space inside the oxygen concentrator. The connection between the compressor's outlet and the two-position five-way valve of the separator through this utility model can also effectively reduce the noise of the entire machine.

[0010] Furthermore, the free end of the intake pipe is conical, and the inner wall of the free end of the exhaust pipe is also conical.

[0011] Therefore, the conical inlet pipe at its free end facilitates connection to the compressor's outlet, and the conical outlet pipe at its free end facilitates connection to the inlet of the two-position five-way valve on the separator.

[0012] Furthermore, the housing includes an upper shell and a base, which are fastened together and together enclose an air passage. The air inlet pipe and the air outlet pipe are both located on the base.

[0013] Therefore, the shell is assembled from the upper shell and the base, which facilitates processing and shaping.

[0014] Furthermore, the upper shell is provided with an air passage groove, and the base covers the air passage groove to form an air passage.

[0015] Therefore, the upper shell and the base together enclose and form the air passage, which facilitates the processing and shaping of the air passage.

[0016] Furthermore, the upper shell has a groove on the end face facing the base, the groove is placed around the outer periphery of the air passage groove, and the base has a protrusion on the end face facing the upper shell that matches the groove. The upper shell and the base are fastened together and the protrusion is inserted into the groove.

[0017] Therefore, the upper shell and the base can be securely assembled together through the interlocking of protrusions and grooves, which also ensures the airtightness of the shell after assembly.

[0018] Furthermore, the upper shell is provided with a fixing plate for fixing to the compressor cover of the oxygen generator, and the fixing plate is provided with fixing holes.

[0019] Therefore, after the air inlet pipe is connected to the air outlet of the oxygen concentrator's compressor and the air outlet pipe is connected to the two-position five-way valve of the oxygen concentrator's separation tower, screws are passed through the fixing holes on the fixing plate and screwed onto the compressor housing of the oxygen concentrator to ensure that the connector of this utility model is firmly fixed on the compressor housing.

[0020] Furthermore, there are two fixing plates, which are located on both sides of the upper shell.

[0021] Therefore, the connector of this utility model can be stably fixed to the compressor housing by means of two fixing plates.

[0022] Furthermore, the side of the base is provided with a limiting plate for limiting the air outlet on the compressor of the oxygen concentrator.

[0023] Therefore, when the air inlet pipe is connected to the air outlet of the oxygen concentrator's compressor and the air outlet pipe is connected to the two-position five-way valve of the oxygen concentrator's separation tower, the air outlet on the oxygen concentrator's compressor can rest against the limit plate to prevent the air outlet on the compressor from shaking during the compressor's operation.

[0024] Furthermore, a ring of pointed protrusions made of soft plastic is provided on the end face of the protrusion facing the bottom of the groove.

[0025] Therefore, when the protrusion on the base is inserted into the groove on the upper shell, the pointed protrusion on the protrusion will be squeezed by the inner bottom of the groove, thereby further improving the sealing between the upper shell and the base after assembly and preventing gas leakage.

[0026] Furthermore, the end of the upper shell is provided with a fastening groove for fastening onto the compressor cover of the oxygen generator.

[0027] Therefore, when the air inlet pipe is connected to the air outlet of the oxygen generator compressor and the air outlet pipe is connected to the two-position five-way valve of the oxygen generator separator tower, the snap-fit ​​groove at the end of the upper shell can be snapped onto the corresponding protrusion on the compressor cover, further improving the stability of the connection installation.

[0034] See Figures 1 to 4 A connector for connecting a compressor and a valve body, comprising a housing 1.

[0035] The housing 1 is made of rigid plastic, and the material of the housing 1 can be PP, ABS, etc.

[0036] See Figure 1 and Figure 2 The housing 1 has an air passage formed inside it. An air inlet pipe 11 is provided at one end of the housing 1, and an air outlet pipe 12 is provided at the other end of the housing 1. Both the air inlet pipe 11 and the air outlet pipe 12 are connected to the air passage inside the housing 1, and both the air inlet pipe 11 and the air outlet pipe 12 are located on the same side of the housing 1. Figure 1 and Figure 2 Both the inlet pipe 11 and the outlet pipe 12 have their free ends facing downwards. The housing 1 is zigzag-shaped, which effectively utilizes the space between the compressor outlet and the two-position five-way valve of the separator, without taking up additional space inside the oxygen concentrator. See section 3 for details. Figure 4 The housing 1 includes an upper shell 101 and a base 102, which are fastened together. An air inlet pipe 11 and an air outlet pipe 12 are formed on the base 102. The air inlet pipe 11 and the air outlet pipe 12 are located at the two ends of the base 102 respectively. The housing 1 is formed by assembling the upper shell 101 and the base 102, which is convenient for processing and forming.

[0037] See Figure 4 The free end of the inlet pipe 11 is conical, and the inner wall of the free end of the outlet pipe 12 is conical. The conical free end of the inlet pipe 11 facilitates connection to the outlet of the compressor, and the conical inner wall of the outlet pipe 12 facilitates connection to the inlet of the two-position five-way valve of the separation tower.

[0038] See Figure 4An air passage groove 13 is formed on the upper shell 101. The air passage groove 13 is in the shape of a zigzag line. The direction of the zigzag line along the length of the air passage groove 13 is consistent with the direction of the zigzag line of the shell 1 as a whole. When the upper shell 101 and the base 102 are fastened together, the base 102 covers the opening of the air passage groove 13 to form an air passage. That is, when the upper shell 101 and the base 102 are fastened together, the two together enclose and form an air passage.

[0039] See Figure 4 A groove 14 is formed on the end face of the upper shell 101 facing the base 102. The groove 14 is arranged around the outer periphery of the air passage groove 13. A protrusion 15 that matches the groove 14 is formed on the end face of the base 102 facing the upper shell 101. The upper shell 101 and the base 102 are fastened together and the protrusion 15 on the base 102 is inserted into the groove 14 of the upper shell 101. After the upper shell 101 and the base 102 are fastened together, they can be firmly pressed together by ultrasonic equipment. The upper shell 101 and the base 102 can be stably assembled together by the insertion and cooperation of the protrusion 15 and the groove 14, and the sealing of the shell 1 can also be ensured after the two are assembled.

[0040] See Figure 3 A ring of pointed protrusions 151 made of soft plastic is integrally formed on the end face of the protrusion 15 facing the bottom of the groove 14. When the protrusion 15 on the base 102 is inserted into the groove 14 on the upper shell 101, the pointed protrusions 151 on the protrusion 15 will be squeezed by the bottom of the groove 14, thereby further improving the sealing between the upper shell 101 and the base 102 after assembly and preventing gas leakage. The pointed protrusions 151 are equivalent to sealing rings to improve the sealing between the upper shell 101 and the base 102.

[0041] See Figures 1 to 4 The upper shell 101 has a fixing plate 16 formed on it for fixing to the compressor housing of the oxygen concentrator. The fixing plate 16 has fixing holes 161. After the air inlet pipe 11 is connected to the air outlet of the oxygen concentrator compressor and the air outlet pipe 12 is connected to the two-position five-way valve of the oxygen concentrator's separation tower, screws are screwed onto the compressor housing of the oxygen concentrator by passing through the fixing holes 161 on the fixing plate 16, ensuring that the connector of this utility model can be firmly fixed to the compressor housing. In this embodiment, there are two fixing plates 16, which are located on both sides of the upper shell 101. The connector of this utility model can be stably fixed to the compressor housing by the two fixing plates 16.

[0042] See Figure 2 and Figure 4The side of the base 102 is formed with a limiting plate 17 for limiting the air outlet on the compressor of the oxygen concentrator. When the air inlet pipe 11 is connected to the air outlet of the compressor of the oxygen concentrator and the air outlet pipe 12 is connected to the two-position five-way valve of the separation tower of the oxygen concentrator, the air outlet on the compressor of the oxygen concentrator can abut against the limiting plate 17 to prevent the air outlet on the compressor from shaking during the operation of the compressor.

[0043] See Figure 4 The upper shell 101 has a snap-fit ​​groove 18 formed at its end for snapping onto the compressor cover of the oxygen generator. When the air inlet pipe 11 is connected to the air outlet of the oxygen generator compressor and the air outlet pipe 12 is connected to the two-position five-way valve of the oxygen generator's separation tower, the snap-fit ​​groove 18 at the end of the upper shell 101 can snap onto the corresponding protrusion on the compressor cover, further improving the stability of the connector installation of this utility model.

[0044] See Figures 1 to 4 The connector of this utility model has an inlet pipe 11 connected to the outlet of the oxygen concentrator's compressor, and an outlet pipe 12 connected to the two-position five-way valve of the oxygen concentrator's separator. The outlet of the oxygen concentrator's compressor abuts against the limiting plate 17. Simultaneously, the snap-fit ​​groove 18 at the end of the upper shell 101 is snapped onto the corresponding protrusion on the compressor cover. Then, two screws are passed through the fixing holes 161 on the two fixing plates 16 and screwed onto the compressor cover of the oxygen concentrator. At this point, the connector of this utility model is installed, and the compressed gas generated by the oxygen concentrator's compressor can pass through the inlet pipe 11 and the housing 1... The air passage and the air outlet pipe 12 enter the two-position five-way valve of the separation tower; the connector of this utility model, the housing 1 is made of hard plastic, and the air inlet pipe 11 and the air outlet pipe 12 are located on the same side of the housing 1, which is convenient for assembly. During the operation of the oxygen generator, the problem of pipe bursting and falling off can be avoided. Moreover, since the housing 1 is zigzag-shaped, the space between the air outlet of the compressor and the two-position five-way valve of the separation tower can be effectively utilized without occupying additional space inside the oxygen generator. The connection between the air outlet of the compressor and the two-position five-way valve of the separation tower through the connector of this utility model can also effectively reduce the noise of the whole machine.

[0045] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art in conjunction with existing common knowledge fall within the protection scope of this utility model.
