[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-7 Describes an oxygen generating device 100 according to an embodiment of the present invention.

[0032] refer to Figures 1-4 According to the first aspect of the present invention, an oxygen generating device 100 includes: a device housing 10 and an oxygen generating component 20.

[0033] The device housing 10 has a receiving cavity 13, and the device housing 10 has an air inlet structure 15 and an air outlet structure that communicate with the receiving cavity 13.

[0034] For example, fresh outdoor air can enter the receiving cavity 13 through the air intake structure 15, and the gas in the receiving cavity 13 can be discharged through the air outlet structure. By forming the air intake structure 15 and the air outlet structure communicating with the receiving cavity 13 on the device housing 10, the use of structures for ventilation and heat dissipation, such as fans, can be reduced, saving space inside the device housing 10 and reducing costs.

[0035] The oxygen generating assembly 20 is disposed in the receiving cavity 13 and is used to generate oxygen. The oxygen generating assembly 20 includes a pump 30 and a wire guide 40. The wire harness connected to the pump 30 is a pump wire harness 301. The wire guide 40 has a wire hole 411 for the pump wire harness 301 to pass through. At least a portion of the wire guide 40 is located between the pump wire harness 301 and the pump 30 to separate the pump wire harness 301 from the pump 30.

[0036] For example, the oxygen generating device 100 may include a separation membrane assembly 21, which has an oxygen enrichment chamber. The separation membrane assembly 21 is used to enrich oxygen in the air into the oxygen enrichment chamber. The inlet of the pump 30 is connected to the separation membrane assembly 21 and communicates with the oxygen enrichment chamber. The outlet of the pump 30 is connected to an oxygen output pipeline.

[0037] For example, at least a portion of the wire guide 40 may be located between the pump harness 301 and the pump 30. This could be a part of the wire guide 40 located between the pump harness 301 and the pump 30, or the entire wire guide 40 may be located between the pump harness 301 and the pump 30.

[0038] If the pump wiring harness 301 is not secured by components such as the wire guide 40, the pump wiring harness 301 placed inside the device housing 10 is easily displaced from its original installation position and comes into contact with the pump 30 under the blowing of the airflow in the receiving cavity 13. By positioning at least a portion of the wire guide 40 between the pump wiring harness 301 and the pump 30 to separate the pump wiring harness 301 and the pump 30, direct contact between the pump wiring harness 301 and the pump 30 is avoided. This prevents the pump wiring harness 301 from being worn due to vibration and friction generated by the pump 30 during operation, and also prevents the internal structure of the pump wiring harness 301 from being exposed, causing the pump wiring harness 301 to fail or leak electricity, such as electrical wires, thereby extending the service life of the pump wiring harness 301.

[0039] According to the oxygen generating device 100 of this utility model embodiment, by providing a wire guide 40 and having a wire hole 411 for the pump wiring harness 301 to pass through on the wire guide 40, the wire guide 40 can fix the pump wiring harness 301; and by positioning at least a portion of the wire guide 40 between the pump wiring harness 301 and the pump 30 to separate the pump wiring harness 301 and the pump 30, it is possible to prevent the pump wiring harness 301 from being worn due to vibration and friction generated by the pump 30 during operation, thereby extending the service life of the pump wiring harness 301.

[0040] According to some embodiments of this utility model, the cable guide 40 is made of a flexible material. By making the cable guide 40 a flexible material, the noise generated when the pump 30 vibrates and rubs against the cable guide 40 can be reduced, and the wear of the cable guide 40 can also be reduced.

[0041] According to some embodiments of this utility model, the wire guide 40 is a heat-insulating material. By making the wire guide 40 a heat-insulating material, the heat transferred to the pump wiring harness 301 during pump 30 operation can be reduced, thereby reducing the risk of the pump wiring harness 301 burning out or failing due to overheating.

[0042] According to some embodiments of this utility model, the cable guide 40 is a rubber part or a silicone part.

[0043] Both rubber and silicone parts have high elasticity, high temperature resistance, and wear resistance, strong chemical stability, and good insulation properties.

[0044] By making the wire guide 40 a rubber or silicone part, the noise generated when the pump 30 vibrates and rubs against the wire guide 40 can be reduced, as can the wear on the wire guide 40. It can also reduce the heat transferred to the pump wiring harness 301 when the pump 30 is operating, thereby reducing the risk of the pump wiring harness 301 burning out or failing due to overheating. When the pump wiring harness 301 is damaged, the wire guide 40 can act as insulation to prevent the conductors inside the pump wiring harness 301 from being exposed, reducing the risk of leakage and improving the safety of the oxygen generator 100 operation.

[0045] refer to Figures 2-4 According to some embodiments of the present invention, the wire guide 40 is fixed to the pump 30.

[0046] For example, the line guide 40 can be fixed to the pump 30 by a fastener or by adhesive.

[0047] By fixing the wire guide 40 to the pump 30, the stability of the wire guide 40 installation can be improved, and the installation between the pump harness 301, the pump 30 and the wire guide 40 can be made more compact, thereby improving the space utilization rate in the receiving cavity 13 and saving space in the device housing 10.

[0048] refer to Figures 1-4 According to some embodiments of the present invention, the pump 30 includes a pump body 31 and a mounting lug 32. The mounting lug 32 is connected to the outer wall of the pump body 31, and the mounting lug 32 is connected to the device housing 10 by a fastening assembly 50. The wire guide 40 includes a wire guide portion 41 and a fixing portion 42. The wire guide portion 41 has a wire guide hole 411, and the fixing portion 42 is fixed to the fastening assembly 50.

[0049] For example, there can be one or more mounting lugs 32. When there are multiple mounting lugs 32, they are arranged at intervals along the circumference of the pump body 31.

[0050] For example, the fastening component 50 can be a component in which bolt 52 and nut 53 mate, or it can be a rivet or pin, etc.

[0051] For example, the fixing part 42 can be fixed to the fastening component 50 by means of snap-fit ​​connection, interference fit, etc.

[0052] By connecting the mounting lug 32 to the device housing 10 via the fastening assembly 50, the stability of the connection between the pump 30 and the device housing 10 can be enhanced, preventing the pump 30 from vibrating and deviating from its original installation position during operation. Furthermore, by dividing the wire guide 40 into two parts, the wire guide part 41 and the fixing part 42, the pump wiring harness 301 passes through the wire guide hole 411, and the fixing part 42 of the wire guide 40 is fixed to the fastening assembly 50. The fastening assembly 50 can be used to install and fix the wire guide 40. To a certain extent, the fixing part 42 of the wire guide 40 can better separate the fastening assembly 50 from the pump wiring harness 301, and better avoid wear caused by contact between the wiring harness and the fastening assembly 50.

[0053] refer to Figures 3-4 According to some embodiments of the present invention, a positioning cavity 421 is formed in the fixing part 42, and a portion of the fastening component 50 is accommodated in the positioning cavity 421.

[0054] For example, the shape of the positioning cavity 421 may be similar to the size and shape of a portion of the fastening component 50, so as to accommodate a portion of the fastening component 50 within the positioning cavity 421, and one end of the fastening component 50 accommodated in the positioning cavity 421 may abut against the inner wall of the positioning cavity 421 in the vertical direction.

[0055] By accommodating a portion of the fastening assembly 50 within the positioning cavity 421, the fixing part 42 can cover the portion of the fastening assembly 50 near the pump wiring harness 301, better preventing wear caused by contact between the wiring harness and the fastening assembly 50. This also reduces contact between the fastening assembly 50 and the wire guide part 41, decreasing the risk of the fastening assembly 50 scratching or abrading the pump wiring harness 301, thereby extending the service life of the pump wiring harness 301. Furthermore, it makes the installation and fixing of the wire guide 40 more convenient, facilitating its disassembly, installation, and replacement. Additionally, by accommodating a portion of the fastening assembly 50 within the positioning cavity 421 to install and fix the wire guide 40, the assembly of the wire guide 40 and the fastening assembly 50 can be made more compact.

[0056] refer to Figures 3-4 According to some embodiments of this utility model, the wire guide 40 is located above the mounting lug 32, the wire guide portion 41 is located above the fixing portion 42, and the portion of the fastening assembly 50 above the mounting lug 32 is a mating structure 51, which is accommodated in the positioning cavity 421. By placing the wire guide 40 above the mounting lug 32, the space above the mounting lug 32 can be effectively utilized, saving space ratio of the wire guide 40. Furthermore, by placing the wire guide portion 41 above the fixing portion 42, the wire guide portion 41 is moved away from the mounting lug 32, reducing the contact between the mounting lug 32 and the pump wiring harness 301. This prevents vibration and friction from the pump 301 during operation from causing wear on the pump wiring harness 301, thereby extending the service life of the pump wiring harness 301.

[0057] refer to Figures 3-4 According to some embodiments of the present invention, the outer periphery of the mating structure 51 has a first limiting protrusion 531, and the inner wall of the positioning cavity 421 has a second limiting protrusion 422. The second limiting protrusion 422 is located below the first limiting protrusion 531 and abuts against the first limiting protrusion 531 in the vertical direction.

[0058] For example, there may be one or more first limiting protrusions 531. When there is one first limiting protrusion 531, it may be an annular protrusion extending circumferentially along the fastening assembly 50. When there are multiple first limiting protrusions 531, they may be arranged at intervals circumferentially along the fastening assembly 50.

[0059] For example, there may be one or more second limiting protrusions 422. When there is one second limiting protrusion 422, it may be an annular protrusion extending circumferentially along the fastening assembly 50. When there are multiple second limiting protrusions 422, the multiple first limiting protrusions 531 may be arranged at intervals along the circumferential direction of the fastening assembly 50.

[0060] By positioning the second limiting protrusion 422 below the first limiting protrusion 531 and abutting against the first limiting protrusion 531 in the vertical direction, the first limiting protrusion 531 can limit the second limiting protrusion 422, thereby enhancing the stability of the connection between the mating structure 51 and the positioning cavity 421 and preventing the wire sheath from detaching from the fastening assembly 50.

[0061] refer to Figures 3-4 According to some embodiments of the present invention, at least one of the first limiting protrusion 531 and the second limiting protrusion 422 is an annular shape extending circumferentially along the fastening assembly 50.

[0062] For example, at least one of the first limiting protrusion 531 and the second limiting protrusion 422 may be an annular ring extending circumferentially along the fastening assembly 50. The first limiting protrusion 531 may be an annular ring extending circumferentially along the fastening assembly 50, the second limiting protrusion 422 may be an annular ring extending circumferentially along the fastening assembly 50, or both the first limiting protrusion 531 and the second limiting protrusion 422 may be annular rings extending circumferentially along the fastening assembly 50.

[0063] By making at least one of the first limiting protrusion 531 and the second limiting protrusion 422 annularly extending along the circumference of the fastening assembly 50, the first limiting protrusion 531 can also maintain contact with the second limiting protrusion 422 in the vertical direction when the fastening assembly 50 and the mating structure 51 rotate relative to each other, further enhancing the stability of the connection between the mating structure 51 and the positioning cavity 421, and making it less likely for the wire sheath to detach from the fastening assembly 50 when the pump 30 vibrates during operation.

[0064] refer to Figures 3-4 According to some embodiments of the present invention, the fastening assembly 50 includes a bolt 52 and a nut 53. The bolt 52 passes through the device housing 10 and the mounting lug 32. The nut 53 is threadedly connected to the bolt 52 and is located above the mounting lug 32. The mating structure 51 includes the portion of the nut 53 and the portion of the bolt 52 located above the mounting lug 32. A first limiting protrusion 531 is formed on the outer periphery of the nut 53.

[0065] For example, a first limiting protrusion 531 is formed on the outer periphery of the lower end of the nut 53 and abuts against the second limiting protrusion 422, and the upper end of the nut 53 can abut against the inner wall of the positioning cavity 421.

[0066] The mounting lug 32 is connected to the device housing 10 by bolt 52 and nut 53, thereby allowing the pump 30 to be installed and fixed inside the device housing 10. This also facilitates the installation of the pump 30 onto or from the device housing 10. Furthermore, by forming a first limiting protrusion 531 on the outer periphery of the nut 53, the stability of the connection between the mating structure 51 and the positioning cavity 421 is enhanced, preventing the wire sheath from detaching from the fastening assembly 50.

[0067] refer to Figures 3-4 According to some embodiments of the present invention, the fastening assembly 50 further includes a shock-absorbing pad 54, which is sleeved on the outer periphery of the bolt 52 and located below the nut 53.

[0068] For example, the shock-absorbing foot pad 54 can be made of rubber or silicone.

[0069] For example, a portion of the shock-absorbing foot pad 54 may be located between the mounting lug 32 and the device housing 10, wherein the device housing 10 may include a base plate 11 and a side plate 12, and a portion of the shock-absorbing foot pad 54 may be connected between the mounting lug 32 and the base plate 11.

[0070] For example, a portion of the shock-absorbing foot pad 54 may be located between the mounting lug 32 and the fastening assembly 50.

[0071] By providing a shock-absorbing pad 54 in the fastening assembly 50, when the pump 30 operates and generates vibration, the shock-absorbing pad 54 can play a buffering role, reducing the degree to which the fastening assembly 50 is vibrated by the pump 30 and causes the device housing 10 to vibrate, thereby reducing the wear between the fastening assembly 50 and the pump 30, and also reducing the wear between the fastening assembly 50 and the device housing 10.

[0072] refer to Figures 3-4 According to some embodiments of the present invention, the surface of the wire guide 40 facing the pump body 31 is formed as a contoured surface 401, and the surface of the pump body 31 facing the wire guide 40 is a mating surface 311. The contoured surface 401 and the mating surface 311 have similar shapes.

[0073] For example, both the contour surface 401 and the mating surface 311 are arc-shaped.

[0074] By forming a contoured surface 401 on the side of the line guide 40 facing the pump body 31, and making it similar in shape to the mating surface 311 formed on the surface of the pump body 31 facing the line guide 40, the line guide 40 fits the pump body 31 better, making the line guide 40 less prone to wear, and also saving the space occupied by the line guide 40 around the pump 30.

[0075] refer to Figures 3-4According to some embodiments of the present invention, a wire-passing notch 412 is formed at the top of the wire-passing part 41. The wire-passing notch 412 communicates with the wire-passing hole 411 and is used to guide the pump wire harness 301 into the wire-passing hole 411.

[0076] For example, the mating structure 51 of the fastening component 50 can be accommodated in the positioning cavity 421 of the wire guide 40 to connect the wire guide 40 with the fastening component 50. Then, the pump wire harness 301 can be guided into the wire hole 411 of the wire guide 40 through the wire notch 412 to fix the pump wire harness 301. When the wire guide 40 is removed, the pump wire harness 301 can be taken out from the wire hole 411 through the wire notch 412 first, and then the wire guide 40 can be separated from the fastening component 50.

[0077] By forming a wire passage notch 412 at the top of the wire passage part 41 and communicating with the wire passage hole 411, it is more convenient to install the pump wiring harness 301 on or remove it from the wire passage protector 40. It also facilitates the installation and disassembly of the wire passage protector 40, and the maintenance and replacement of the wire passage protector 40 can be completed without disassembling the pump wiring harness 301.

[0078] refer to Figure 1 According to some embodiments of the present invention, the device housing 10 includes a base plate 11 and a side plate 12. The side plate 12 extends circumferentially along the base plate 11 and together with the base plate 11 defines a receiving cavity 13. The pump 30 is mounted on the base plate 11. The side plate 12 includes a plurality of side plates 121 connected sequentially along the circumferential direction of the base plate 11. At least some adjacent side plates 121 are connected by fasteners 14. A portion of the wire guide 40 is located between the fastener 14 and the pump wiring harness 301.

[0079] For example, at least some of the adjacent side panels 121 are connected by fasteners 14. This could be a partial connection between adjacent side panels 121 or a connection between all adjacent side panels 121 by fasteners 14.

[0080] For example, the air intake structure 15 is formed on the side panel 12, and the air outlet structure is formed on the bottom plate 11.

[0081] By placing a portion of the wire guide 40 between the fastener 14 and the pump wiring harness 301, the risk of the fastener 14 scratching or abrading the pump wiring harness 301 can be reduced, thereby extending the service life of the pump wiring harness 301.

[0082] refer to Figures 5-7An outdoor unit 200 of an air conditioner according to a second aspect of the present invention includes: an outdoor unit body 60 and an oxygen generating device 100 according to a first aspect of the present invention. The outdoor unit body 60 includes an outdoor unit housing 61 and a heat exchange and exhaust assembly and a compressor assembly disposed within the outdoor unit housing 61. The outdoor unit housing 61 is provided with an outdoor air inlet 63 and an outdoor air outlet 62. The oxygen generating device 100 is installed in the outdoor unit housing 61 and has an oxygen output pipeline.

[0083] For example, the heat exchange and exhaust assembly may include an outdoor heat exchanger and an outdoor fan. Air enters the outdoor unit housing 61 from the outdoor air inlet 63, exchanges heat with the outdoor heat exchanger, and is then exhausted to the outside from the outdoor air outlet 62 under the drive of the outdoor fan.

[0084] For example, the oxygen generator 100 can be installed on the top of the outdoor unit housing 61 or on the side of the outdoor unit housing 61.

[0085] According to the embodiment of the present utility model, the outdoor unit 200 of the air conditioner is provided with the above-mentioned oxygen generating device 100.

The wire guide 40 can fix the pump wire harness 301. Furthermore, by placing at least a portion of the wire guide 40 between the pump wire harness 301 and the pump 30 to separate the pump wire harness 301 and the pump 30, it is possible to prevent the pump wire harness 301 from being worn due to vibration and friction generated by the pump 30 during operation, thereby extending the service life of the pump wire harness 301.

[0086] According to some embodiments of the present invention, the oxygen generating device 100 is detachably connected to the outdoor unit housing 61.

[0087] For example, the oxygen generator 100 can be connected to the outdoor unit housing 61 by screws.

[0088] By making the oxygen generator 100 detachably connected to the outdoor unit housing 61, the installation and removal of the oxygen generator 100 are highly flexible, facilitating the maintenance or replacement of the oxygen generator 100.

[0089] refer to Figure 6 According to some embodiments of this utility model, the oxygen generator 100 is located on the top of the outdoor unit body 60. By placing the oxygen generator 100 on the top of the outdoor unit body 60, the space at the top of the outdoor unit body 60 can be utilized, reducing the occupation of horizontal space. It also facilitates the installation of the oxygen generator 100 onto the outdoor unit body 60, improving the assembly efficiency of the oxygen generator 100. When the oxygen generator 100 or the outdoor unit body 60 needs maintenance, the efficiency of installation and disassembly of the oxygen generator 100 and the outdoor unit body 60 can also be improved.

[0090] refer to Figures 6-7 According to some embodiments of this utility model, the oxygen generating device 100 is installed on the top of the outdoor unit housing 61.

The oxygen generating assembly 20 is located inside the device housing 10. The bottom plate 11 of the device housing 10 has an air outlet. The air outlet is located directly above the fan chamber and connects the receiving cavity 13 inside the device housing 10 with the fan chamber inside the outdoor unit housing 61. The side panel 12 of the device housing 10 has an air inlet.

[0091] When the outdoor unit 200 of the air conditioner is working, the outdoor fan drives outside air to enter the fan cavity from the air inlet, exchange heat with the outdoor heat exchanger, and then discharge it from the air outlet. At the same time, since the receiving cavity 13 inside the device housing 10 is connected to the fan cavity through the air outlet, it can also drive outside air to enter the receiving cavity 13 from the air inlet. After the air entering the receiving cavity 13 is processed by the oxygen generating component 20, oxygen is separated and delivered to the indoor unit through the oxygen output pipe.

[0092] refer to Figures 6-7 According to some embodiments of this utility model, the outdoor unit housing 61 includes a housing body 64 and a housing top cover 65. The heat exchange and exhaust assembly and the compressor assembly are disposed inside the housing body 64. The housing body 64 is provided with an air inlet and an air outlet. The oxygen generator 100 is disposed on the top of the housing body 64. The housing top cover 65 covers the top of the side panel 12.

[0093] By placing the oxygen generator 100 on the top of the main casing 64, the space at the top of the main casing 64 can be utilized, reducing the occupation of horizontal space. This also facilitates the installation of the oxygen generator 100 onto the main casing 64, improving the assembly efficiency of the oxygen generator 100. When the oxygen generator 100 or the outdoor unit 60 needs maintenance, the efficiency of installation and disassembly of the oxygen generator 100 and the outdoor unit 60 can also be improved. Furthermore, by placing the top cover 65 on the top of the side panel 12, there is no need to equip the oxygen generator 100 with a separate top cover, saving space in the outdoor unit 200 and reducing production costs.

[0094] An air conditioner according to a third aspect of the present invention includes: an indoor unit; and an outdoor unit 200 according to a second aspect of the present invention, wherein an oxygen output pipeline is used to deliver oxygen to the indoor unit.

[0095] For example, an oxygen output pipe can deliver oxygen to the air inlet, duct, or outlet of the indoor unit of an air conditioner.

[0096] According to the embodiment of the present invention, the air conditioner, by setting the above-mentioned indoor unit, provides a wire guide 40 in the oxygen generating device 100 of the indoor unit and provides a wire guide hole 411 for the pump wiring harness 301 to pass through on the wire guide 40. The wire guide 40 can fix the pump wiring harness 301. Furthermore, by positioning at least a portion of the wire guide 40 between the pump wiring harness 301 and the pump 30 to separate the pump wiring harness 301 and the pump 30, it is possible to prevent the pump wiring harness 301 from being worn due to vibration and friction generated by the pump 30 during operation, thereby extending the service life of the pump wiring harness 301.

[0097] The following is for reference. Figures 1-7 Describes an oxygen generating device 100 according to some embodiments of the present invention.

[0098] In this embodiment, the oxygen generating device 100 includes: a device housing 10 and an oxygen generating component 20.

The wire harness connected to the pump 30 is a pump wire harness 301. The wire guide 40 has a wire through hole 411 for the pump wire harness 301 to pass through. A part of the wire guide 40 is located between the pump wire harness 301 and the pump 30 to separate the pump wire harness 301 and the pump 30.

[0100] Among them, the wire guide 40 is a rubber part with heat insulation properties, and the wire guide 40 is fixed to the pump 30.

[0101] Pump 30 includes pump body 31 and mounting lug 32. Mounting lug 32 is connected to the outer wall of pump body 31 and is connected to device housing 10 by fastening assembly 50.

[0102] The cable guide 40 includes a cable guide portion 41 and a fixing portion 42. The cable guide portion 41 is located above the fixing portion 42 and has a cable guide hole 411. The fixing portion 42 is fixed to the fastening assembly 50.

[0103] A positioning cavity 421 is formed inside the fixing part 42. The wire guide 40 is located above the mounting lug 32. The part of the fastening assembly 50 located above the mounting lug 32 is a mating structure 51, which is accommodated in the positioning cavity 421.

[0104] The fastening assembly 50 includes a bolt 52 and a nut 53. The bolt 52 passes through the device housing 10 and the mounting lug 32. The nut 53 is threadedly connected to the bolt 52 and is located above the mounting lug 32. The mating structure 51 includes the portion of the nut 53 and the portion of the bolt 52 located above the mounting lug 32. A first limiting protrusion 531 is formed on the outer periphery of the nut 53. A second limiting protrusion 422 is formed on the inner wall of the positioning cavity 421. Both the first limiting protrusion 531 and the second limiting protrusion 422 are annular rings extending circumferentially along the fastening assembly 50. The second limiting protrusion 422 is located below the first limiting protrusion 531 and abuts against the first limiting protrusion 531 in the vertical direction.

[0105] The fastening assembly 50 also includes a shock-absorbing pad 54, which is fitted around the outer periphery of the bolt 52 and located below the nut 53.

[0106] The surface of the cable guide 40 facing the pump body 31 is formed as a contoured surface 401, and the surface of the pump body 31 facing the cable guide 40 is a mating surface 311. The contoured surface 401 and the mating surface 311 have similar shapes. A cable pass-through notch 412 is formed at the top of the cable pass-through portion 41. The cable pass-through notch 412 communicates with the cable pass-through hole 411 and is used to guide the pump cable harness 301 into the cable pass-through hole 411.

[0107] The device housing 10 includes a base plate 11 and side panels 12. The side panels 12 extend circumferentially along the base plate 11 and together with the base plate 11 define a receiving cavity 13. The pump 30 is mounted on the base plate 11.

[0108] When installing the cable guide 40, the mating structure 51 of the fastening assembly 50 can be accommodated in the positioning cavity 421 of the cable guide 40 first. The elastic deformation of the cable guide 40 causes the nut 53 to engage in the positioning cavity 421, and the first limiting protrusion 531 and the second limiting protrusion 422 to abut against each other in the vertical direction. This connects the cable guide 40 to the fastening assembly 50 and prevents it from easily disengaging. Then, the pump wiring harness 301 is guided through the cable notch 412. The pump wiring harness 301 is fixed in the wire hole 411 of the wire guide 40. When the wire guide 40 is removed, the pump wiring harness 301 can be taken out from the wire hole 411 through the wire notch 412, and then the wire guide 40 can be lifted from the fastening assembly 50. The elastic deformation of the wire guide 40 separates the second limiting protrusion 422 from the first limiting protrusion 531, so as to separate the wire guide 40 from the fastening assembly 50.
