Description

Technical Field

[0001] This utility model relates to ventilation therapy equipment, specifically to a main support for an oxygen generator. Background Technology

[0002] Portable oxygen concentrators utilize the pressure swing adsorption (PSA) principle, using ambient air as feedstock. Under normal temperature and low pressure conditions, they leverage the property of molecular sieves that increase the adsorption capacity for nitrogen (adsorbate) in the air when pressurized and decrease it when depressurized, forming a rapid cycle of pressurized adsorption and depressurized desorption, thus separating oxygen and nitrogen from the air. Portable oxygen concentrators are particularly suitable for patients requiring long-term oxygen therapy. Firstly, their small size and light weight make them easy to carry, allowing patients to obtain oxygen anytime, anywhere, whether at home, out and about, or traveling. Secondly, portable oxygen concentrators are simple to use, providing a stable oxygen flow through simple operation, making them suitable for the elderly and patients with limited mobility.

[0003] To achieve oxygen production, portable oxygen concentrators are typically equipped with components such as compressors, adsorption towers, control valves, and circuit boards. These components are assembled in a stacked manner and interconnected to form an oxygen production system, according to the oxygen production process requirements. Therefore, the component arrangement in existing portable oxygen concentrators is relatively scattered, and the reliability of connections between related components is poor. After long-term use, minor bumps or use in various postures and angles can easily lead to problems such as air leaks and abnormal noises, affecting the overall performance and oxygen production effect. Furthermore, if the relative positions of different components are not arranged reasonably, it will also result in a large size of the oxygen concentrator, hindering its miniaturization and portability, and even limiting its oxygen production capacity.

[0004] In addition, the core, which consists of the above-mentioned multiple functional components, is enclosed in the main unit housing. When it is necessary to disassemble or assemble components such as the adsorption tower, it is usually necessary to first remove the main unit housing and then remove the adsorption tower from the core or install the adsorption tower in the corresponding position, which is inconvenient for use and maintenance. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of inconvenient maintenance caused by the need to disassemble and install the adsorption tower when removing the main unit casing in existing portable oxygen generators. This invention provides a main support for oxygen generators that allows the adsorption tower to be disassembled and installed without removing the main unit casing, making it convenient for users to replace and maintain the adsorption tower.

[0006] To achieve the above objectives, the present invention provides a main support for an oxygen generator, the main support having a base and an adsorption tower compartment disposed on the base for accommodating an adsorption tower, and the base having an opening at a position corresponding to the adsorption tower compartment, and being configured to allow the adsorption tower to pass through the opening and be inserted into the adsorption tower compartment.

[0007] Preferably, the base is further provided with a compressor compartment arranged horizontally adjacent to the adsorption tower compartment, and the dimension of the adsorption tower compartment in the height direction is larger than that of the compressor compartment, so as to form an installation space above the compressor compartment for installing the intake nitrogen exhaust control module and / or oxygen storage tank, and to allow the intake nitrogen exhaust control module and / or oxygen storage tank to be installed at least partially located within the installation space.

[0008] Preferably, the top wall of the compressor compartment is provided with an air intake and nitrogen exhaust control module mounting base, which is set to be adjacent to the adsorption tower compartment and used to install the air intake and nitrogen exhaust control module.

[0009] Preferably, the mounting base of the intake nitrogen exhaust control module has a sound-absorbing cotton mounting groove and multiple exhaust holes arranged in an array on the bottom wall, so that the nitrogen exhaust port of the intake nitrogen exhaust control module is connected to the external environment through the sound-absorbing cotton installed in the sound-absorbing cotton mounting groove and the exhaust holes in sequence.

[0010] Preferably, the top wall of the compressor compartment is provided with an upwardly extending oxygen storage tank mounting base, so as to allow the oxygen storage tank to be installed above the air intake and nitrogen exhaust control module mounted on the air intake and nitrogen exhaust control module mounting base, and at least partially at the same height as the portion of the adsorption tower compartment that extends beyond the compressor compartment in the height direction.

[0011] Preferably, the top wall of the compressor compartment is further provided with a cooling fan mounting base and / or a speaker mounting base. The cooling fan mounting base and / or speaker mounting base are located on the side of the air intake and nitrogen exhaust control module mounting base away from the adsorption tower compartment, and are used to install the cooling fan and / or speaker.

[0012] Preferably, at a position adjacent to the compressor compartment and the adsorption tower compartment, the main support has a connecting joint mounting part, and when the adsorption tower is inserted into the adsorption tower compartment, the connecting joint installed in the connecting joint mounting part is sealed to the air inlet of the adsorption tower.

[0013] Preferably, on the side of the compressor compartment away from the adsorption tower compartment, the main support forms an air intake component mounting base, which has an ambient air inlet communicating with the external environment and a purified air outlet communicating with the compressor compartment.

[0014] Preferably, one side of the compressor compartment has an opening for inserting or removing the compressor, and the main support forms a power management board mounting base located on the side of the compressor compartment opposite to the opening.

[0015] Preferably, on the side of the compressor compartment away from the adsorption tower compartment, the main support is provided with an air guide for directing cooling air from the external environment toward the side where the power management board mounting base is located.

[0016] Through the above technical solution, the main support of this utility model has an opening formed on its base corresponding to the adsorption tower compartment, allowing users to insert the adsorption tower into the adsorption tower compartment through the opening. This allows the adsorption tower to be installed and removed without removing the main casing outside the core, making it convenient to replace and maintain the adsorption tower of the oxygen generator.

Detailed Implementation

[0039] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0040] In this invention, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the up, down, left, and right positions shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer positions relative to the outline of each component itself. Under normal conditions, an oxygen concentrator using the main support frame of this invention can... Figure 10 The indicated position is on the platform; at this time, the main support is in... Figure 1 and Figure 2 The orientation is shown. For clarity, the relative positions and dimensions of the relevant structures on the main support and the relevant components in the oxygen concentrator will be described below using the terms "horizontal direction" and "height direction." It should be understood that, for portable oxygen concentrators, they can be placed or carried in different postures and angles; therefore, the terms "horizontal direction" and "height direction" only refer to the orientation of the oxygen concentrator and the main support. Figure 1 , Figure 2 and Figure 10 The horizontal and vertical directions when placed in the indicated orientation.

[0041] Figure 1 and Figure 2 A perspective view of a main support 2 for an oxygen generator according to a preferred embodiment of the present invention is shown; Figure 3 and Figure 4 This is a three-dimensional view of the oxygen generator core from the bottom perspective, when the adsorption tower is not installed in the main support. Figures 5 to 12 It shows the basis Figure 1 and Figure 2 The main support 2 shown is used to sequentially install the various components of the oxygen generator onto the main support 2, thus completing the assembly process of the oxygen generator. The three-dimensional structure of the adsorption tower and its top-down views before and after assembly onto the main support 2 are shown in the figure. Figures 13 to 17 As shown in the image.

[0042] like Figures 1 to 4 As shown, the main support 2 of this utility model has a base 210 and an adsorption tower compartment 205 disposed on the base 210 for accommodating the adsorption tower 5. The base 210 has an opening at a position corresponding to the adsorption tower compartment 205, and is configured to allow the adsorption tower 5 (see...) Figure 7 The adsorption tower 5 is inserted into the adsorption tower compartment 205 through the opening. Thus, even when the main unit casing of the oxygen generator is covered by the core unit, the bottom end of the adsorption tower 5 can be exposed from the base 210 of the main support 2, simply by removing the battery box 10 from the main unit (e.g., Figure 11 (The state shown).

[0043] With this configuration, since an opening is formed at the position of the base 210 of the main support 2 corresponding to the adsorption tower compartment 205, the user can insert the adsorption tower 5 into the adsorption tower compartment through this opening. Thus, the adsorption tower 5 can be disassembled and installed without removing the main casing outside the core, which facilitates the replacement and maintenance of the adsorption tower of the oxygen generator.

[0044] Specifically, the shape of the adsorption tower chamber 205 matches that of the adsorption tower 5, and the adsorption tower 5 is surrounded by the adsorption tower 5 on at least multiple sides in the height direction of the adsorption tower chamber 205. It should be noted that the adsorption tower chamber 205 formed by the main support includes a top wall and circumferentially enclosing side walls, wherein the side walls are provided with openings to facilitate heat dissipation of the adsorption tower chamber 205. The base 210 of the main support 2 is provided with a connecting joint 23 for docking with the adsorption tower 5. The adsorption tower 5 is detachably inserted into the adsorption tower chamber 205. When the adsorption tower 5 is inserted into the adsorption tower chamber 205, the air inlet of the adsorption tower 5 is sealed to the connecting joint 23 on the main support 2, so that compressed air can be introduced into the adsorption tower 5 for adsorption oxygen production or nitrogen gas generated by desorption can be discharged from the adsorption tower 5 through the air inlet and nitrogen exhaust control module connected to the connecting joint 23. The adsorption tower 5 may also have an outlet for outputting the produced oxygen, and the sealing connection between the connecting joint 23 and the air inlet is also applicable to the outlet.

[0045] Therefore, this adsorption tower installation structure allows the adsorption tower 5 to be detachably installed into the adsorption tower compartment 205 via a plug-in method, while simultaneously sealing the air inlet of the adsorption tower 5 to the connecting joint 23 located on the adsorption tower compartment 205, so as to seal the connection to the air inlet and nitrogen exhaust pipeline. When it is necessary to replace the molecular sieve, the operator only needs to pull the adsorption tower 5 out of the adsorption tower compartment 205 or plug it into the adsorption tower compartment 205 to complete the disassembly and assembly of the adsorption tower 5, and no additional operation is required to connect the adsorption tower 5 to the relevant connecting pipeline, avoiding airtightness problems or other damage caused by improper operation, with low maintenance difficulty and high safety in use.

[0046] To facilitate the insertion of the adsorption tower 5 into the adsorption tower compartment 205, the main support 2 may have a guide structure 2051 protruding towards the adsorption tower compartment 205 to guide the insertion of the adsorption tower 5 into the adsorption tower compartment 205. Figure 3As shown, the guide structure 2051 can be multiple guide plates extending along the insertion direction of the adsorption tower 5, so as to guide the adsorption tower 5 to be inserted into the adsorption tower compartment 205 in the correct direction.

[0047] After the adsorption tower 5 is inserted into the adsorption tower compartment 205, the adsorption tower 5 needs to be properly secured. For example... Figure 3 and Figure 4 As shown, in a preferred embodiment, the base 210 of the main support 2 may be provided with a latch assembly 216. When the adsorption tower 5 is inserted into a predetermined position within the adsorption tower chamber 205, the latch assembly 216 can abut against the side of the end cap of the adsorption tower 5 opposite to the insertion direction. Thus, when the adsorption tower 5 is installed in place, the latch assembly 216 stops its end cap to prevent the adsorption tower 5 from detaching from the adsorption tower chamber 205.

[0048] Specifically, the latch assembly 216 may include a latch cover 2161 connected to the base 210 of the main support 2, a latch 2163 slidably connected to the latch cover 2161, and a latch spring 2162 elastically abutting between the latch cover 2161 and the latch 2163. The latch spring 2162 is configured to allow the latch 2163 to pop out along a direction perpendicular to the insertion direction of the adsorption tower 5, so that it can abut against the end cap when the adsorption tower 5 is inserted into a predetermined position in the adsorption tower compartment 205. The base 210 of the main support 2 may have a guide groove for guiding the sliding of the latch 2163, thereby preventing the latch 2163 from deflecting during sliding relative to the latch cover 2161. Furthermore, the latch assembly 216 may include two or more latch springs 2162 arranged in parallel, thereby ensuring that the latch 2163 can be smoothly popped out, avoiding jamming or failure to reset. Thus, when the adsorption tower 5 is inserted into the adsorption tower compartment 205, the latch 2163 is driven to retract against the elastic force of the latch spring 2162 until the latch 2163 springs back under the action of the latch spring 2162, making a "click" resetting sound, indicating that the adsorption tower 5 has reached the predetermined position. With this setting, the adsorption tower 5 can be quickly installed into the main support 2 while ensuring accurate installation position, and the latch assembly 216 can prevent the adsorption tower 5 from falling out of the predetermined position.

[0049] Figures 13 to 17 Another form of adsorption tower mounting structure is provided, which secures the adsorption tower 5 in its mounting position via a tamper-evident cover 218 and fastening screws. Specifically, as... Figure 13 and Figure 14 As shown, the adsorption tower 5 in this embodiment has a locking tongue 51 provided on the end cap. Accordingly, as Figure 15As shown, the base 210 of the main support 2 can be equipped with an adsorption tower positioning seat 217. When the adsorption tower 5 is installed in the predetermined position within the adsorption tower chamber 205, the adsorption tower 5 is fixed in its installation position by threaded fasteners passing through the locking tongue 51 and screwing them to the adsorption tower positioning seat 217, as shown. Figure 16 As shown. Compared to the aforementioned latch assembly 216, this adsorption tower installation structure requires tools such as screwdrivers to disassemble and assemble the adsorption tower. Furthermore, as... Figure 17 As shown, an anti-tamper cover plate 218 covering the locking tongue 51 can also be connected to the adsorption tower positioning seat 217.

[0050] The main support 2 of this invention can be formed with a compressor compartment 203 and an adsorption tower compartment 205 arranged adjacent to each other in the horizontal direction, and the dimension of the adsorption tower compartment 205 in the height direction is larger than that of the compressor compartment 203 in the height direction. Therefore, in the portion of the adsorption tower compartment 205 that extends beyond the compressor compartment 203 in the height direction, there is an installation space above the compressor compartment 203. This installation space can be used to install other functional components such as the intake and exhaust nitrogen control module 4. At the same time, the adsorption tower compartment 205 is designed to have a relatively large dimension in the height direction, which allows the adsorption tower 5 installed within it to have a larger volume, which is beneficial for improving the oxygen production capacity of the oxygen generator.

[0051] Therefore, in the main support 2, a corresponding mounting base is provided above the compressor compartment 203 for installing the intake nitrogen exhaust control module 4 and / or the oxygen storage tank 7. These mounting bases allow the intake nitrogen exhaust control module 4 and / or the oxygen storage tank 7 to be installed at least partially at the same height as the portion of the adsorption tower compartment 205 that extends beyond the compressor compartment 203 in the height direction.

[0052] Therefore, the main support 2 of this utility model allows for the integrated installation of key components such as the compressor 3, adsorption tower 5, and air intake / nitrogen exhaust control module 4 and / or oxygen storage tank 7. This ensures reliable and stable connection of the gas paths between these components even in the event of minor impacts or use in various postures and angles, reducing the risk of air leakage or abnormal noise after a period of use. Simultaneously, by setting the adsorption tower compartment 205 to have a larger vertical dimension than the compressor compartment 203, and installing the air intake / nitrogen exhaust control module 4 and / or oxygen storage tank 7 above the compressor compartment 203, the space occupied by other components or structures above and below the adsorption tower can be reduced. This allows the adsorption tower 5 to be set at a higher height, ensuring a higher oxygen production capacity for the oxygen generator. Based on this main support 2, the component arrangement in the oxygen generator is reasonable, avoiding the increase in the size of the oxygen generator caused by increasing the height of the adsorption tower, which is conducive to the miniaturization and portability of the oxygen generator.

[0053] That is, in such Figure 1 and Figure 2In the indicated orientation, the base 210 of the main support 2 can be positioned to contact the table surface. The mounting base can be disposed on the top wall of the compressor compartment 203 to allow the intake nitrogen exhaust control module 4 and / or the oxygen storage tank 7 to be installed above the compressor compartment 203, and at least partially at the same height as the portion of the adsorption tower compartment 205 extending beyond the compressor compartment 203 in the vertical direction. Figure 9 In the assembled state shown, the intake and exhaust nitrogen control module 4 is installed with its highest position not exceeding the top wall of the adsorption tower chamber 205, while the oxygen storage tank 7 is installed with its lower half at the same height as the top area of ​​the adsorption tower chamber 205, and its upper half at the same height as the pressure equalization control component 6 described later. This not only makes full use of the space above the compressor chamber 203, but also increases the storage volume of the oxygen storage tank 7.

[0054] By installing compressor 3 in a relatively low position, the center of gravity of the oxygen concentrator can be lowered when it is placed on the table as shown in the figure, thus making it easier to place stably.

[0055] Specifically, in a preferred embodiment, the mounting base above the compressor compartment 203 may include an intake and exhaust nitrogen control module mounting base 204 formed on the top wall of the compressor compartment 203 for mounting the intake and exhaust nitrogen control module 4. This intake and exhaust nitrogen control module 4 controls the on / off state between the compressor 3 and the adsorption tower 5, and between the adsorption tower 5 and the external environment. Thus, when compression control is required to supply the adsorption tower 5, the intake and exhaust nitrogen control module 4 controls the outlet of the compressor 3 to connect to the inlet of the adsorption tower 5, facilitating the adsorption of nitrogen from the air by the molecular sieve within the adsorption tower 5, thereby producing oxygen. When desorption treatment of the molecular sieve within the adsorption tower 5 is required, the intake and exhaust nitrogen control module 4 controls the adsorption tower 5 to connect to the external environment to discharge nitrogen gas.

[0056] The nitrogen intake and exhaust control module mounting base 204 can be positioned adjacent to the adsorption tower chamber 205 to facilitate the control of nitrogen intake and exhaust. Figure 5 The air intake and nitrogen exhaust pipe 25 and the connecting joint 23 shown in the figure connect the port of the air intake and nitrogen exhaust control module 4 installed thereon to the adsorption tower 5, so as to avoid the reduced reliability of the gas path due to the excessive length of the connecting pipe. An installation space is left above the compressor compartment 203 on the side of the air intake and nitrogen exhaust control module mounting base 204 away from the adsorption tower compartment 205 for arranging the speaker 91 and cooling fan 8, etc., which will be described later.

[0057] Furthermore, the nitrogen intake and exhaust control module mounting base 204 can integrate a nitrogen exhaust silencer. For example, the mounting base 204 may have a sound-absorbing cotton mounting groove (not marked) and multiple exhaust holes arranged in an array on its bottom wall. In the assembled state, the nitrogen exhaust port of the nitrogen intake and exhaust control module 4 can face the sound-absorbing cotton mounting groove, allowing the nitrogen exhaust port of the nitrogen intake and exhaust control module 4 to connect to the external environment sequentially through the sound-absorbing cotton 403 installed in the sound-absorbing cotton mounting groove and the exhaust holes. This configuration reduces the nitrogen exhaust noise during the oxygen concentrator's operation through the sound-absorbing cotton 403 and the exhaust holes, facilitating prolonged use by patients. Preferably, the sound-absorbing cotton installation groove is recessed into the compressor compartment 203, and the exhaust port is located inside the compressor compartment 203, so that the nitrogen exhaust port of the intake nitrogen exhaust control module 4 is first silenced by the sound-absorbing cotton 403, the exhaust port, etc., before being discharged into the compressor compartment 203. Since the noise-reducing cotton attached to the outer wall of the compressor compartment 203 also has the function of noise reduction and sound absorption, secondary noise reduction of the discharged nitrogen can be achieved.

[0058] In a preferred embodiment, an oxygen storage tank mounting base 207 extending upward from the top wall of the compressor compartment 203 may be provided above the compressor compartment 203. This allows the oxygen storage tank 7 to be installed above the intake and exhaust control module 4 mounted on the intake and exhaust control module mounting base 204, and at least partially at the same height as the portion of the adsorption tower compartment 205 that extends beyond the compressor compartment 203 in the height direction. In the illustrated preferred embodiment, the oxygen storage tank mounting base 207 is configured as several pillars extending upward from the top wall of the compressor compartment 203, thereby facilitating the provision of space above the intake and exhaust control module 4 to accommodate the lower half of the oxygen storage tank 7. As mentioned above, by allowing the oxygen storage tank 7 to occupy part of the space above the compressor compartment 203, it is easier to ensure that the oxygen storage tank 7 has a relatively large size in the height direction, which is beneficial to ensuring that it has a large storage space and facilitates stable oxygen supply.

[0059] In the oxygen generator, compressor 3 can be configured as a pair of compression units that alternately compress air to continuously supply compressed air to the adsorption tower. In this case, the pair of compression units can be connected as a single unit and installed horizontally within the compressor compartment 203. Thus, the top wall of the compressor compartment 203 has a considerable length in the direction of the compression units' arrangement, and these areas can be used not only to install the aforementioned air intake and nitrogen exhaust control module 4, but also to house other functional components. Therefore, in a preferred embodiment, a cooling fan mounting base 208 and / or a speaker mounting base 209 formed on the top wall of the compressor compartment 203 can also be provided above the compressor compartment 203. This cooling fan mounting base 208 and / or speaker mounting base 209 is located on the side of the air intake and nitrogen exhaust control module mounting base 204 away from the adsorption tower compartment 205 and is used to mount the cooling fan 8 and / or the speaker 91.

[0060] Thus, the cooling fan 8 can be installed to blow cooling air toward the compressor compartment 203 to ensure adequate cooling of the compressor 3. The speaker 91 can be installed close to the main control board 9, which is mounted above the oxygen storage tank 7 as described later, to avoid excessive wiring and to make full use of the space between the intake and exhaust nitrogen control module 4 and the cooling fan 8.

[0061] As previously mentioned, the port of the intake nitrogen exhaust control module 4 can be connected to the adsorption tower 5 via the intake nitrogen exhaust pipe 25 and the connecting joint 23. Therefore, at a location adjacent to the compressor compartment 203 and the adsorption tower compartment 205, the main support 2 can have a connecting joint mounting portion 213, which can be fixedly or detachably connected to the connecting joint 23. When the adsorption tower 5 is inserted into the adsorption tower compartment 205, the connecting joint 23 is sealed to the intake port of the adsorption tower 5.

[0062] To facilitate the supply of ambient air to the compressor 3, the main support 2 of this invention may also be equipped with an air intake assembly. Specifically, on the side of the compressor compartment 203 away from the adsorption tower compartment 205, the main support 2 forms an air intake assembly mounting base 201. This air intake assembly mounting base 201 has an ambient air inlet 202 (e.g., through the air intake grille 12 of the main housing) connected to the external environment and a purified air outlet 206 connected to the compressor compartment 203. An air intake filter element 21 and a cover plate 22 may be installed on the air intake assembly mounting base 201 so that the ambient air drawn in through the ambient air inlet 202 can be filtered by the air intake filter element 21 and then supplied to the compressor 3 through the purified air outlet 206. By placing the air intake assembly on the side of the compressor compartment 203 away from the adsorption tower compartment 205, the air intake path of the compressor 3 can be shortened, thereby improving the intake efficiency and reducing energy consumption.

[0063] In a preferred embodiment of the main support 2 of this utility model, one side of the compressor compartment 203 may have an opening for inserting or removing the compressor 3, which can be closed by the compressor compartment cover 26. Furthermore, the main support 2 may have a power management board mounting base 214 located on the side of the compressor compartment 203 opposite to this opening. The power management board 24 can be fixed to the main support 2 via this mounting base 214 to control the power supply to the compressor 3, the intake and exhaust nitrogen control module 4, etc. By mounting the power management board 24 on one side of the compressor compartment 203, excessively long connection lines can be avoided, which is beneficial for the assembly and spatial arrangement of the oxygen generator.

[0064] On the side of the compressor compartment 203 away from the adsorption tower compartment 205, the main support 2 may also be equipped with a power connector 27 for connecting to an external power source, so that the power connector 27 is electrically connected to the aforementioned power management board 24, and the power connector 27 may be adjacent to the air intake assembly and be installed to be exposed to the outside through the main unit housing.

[0065] Furthermore, on the side of the compressor compartment 203 away from the adsorption tower compartment 205, the main support 2 can also have an air guide vent 215 for guiding cooling airflow from the external environment toward the side where the power management board mounting base 214 is located. This air guide vent 215 can be implemented by a baffle structure formed on the main support 2 to block cooling airflow toward the side of the main support 2 away from the power management board mounting base 214. With this arrangement, ambient air entering the main housing through the air intake grille 12 on the side where the air intake assembly is located can be directed to the power management board 24 by the air guide vent 215, thereby providing sufficient heat dissipation to the power management board 24.

[0066] To facilitate a better understanding of this utility model, the following is combined with... Figures 5 to 12 The assembly process of the oxygen concentrator based on the main support 2 described above will be illustrated by way of example. In addition to the key functional components related to the main support 2 described above, the following description also involves some other aspects of the oxygen concentrator.

[0067] like Figure 5 As shown, the intake nitrogen exhaust control module 4, including the sound-absorbing cotton 403, can be installed in the intake nitrogen exhaust control module mounting base 204, and one end of the intake nitrogen exhaust pipe 25, which is connected to the connecting connector 23, is connected to the corresponding port of the intake nitrogen exhaust control module 4. The connecting connector 23 is connected to the connecting connector mounting part 213 (see...).
