[0037] In the houses where users live, drain outlets are usually pre-set and the number is fixed. However, with the increase in drainage equipment in users' homes (such as washing machines, shoe washing machines, dishwashers, etc.), it is troublesome to add drain outlets. At present, a multi-way pipe joint (such as a three-way pipe joint) is usually installed at the drain outlet. In this way, the drain pipes of multiple devices can be connected to the drainage interfaces on the multi-way pipe joint, so that multiple devices can share the same drain outlet for drainage. However, the existing multi-way pipe joints have a single shape and a fixed volume, and cannot be flexibly adjusted according to the requirements of the drainage interfaces to be used. As a result, when the demand for the drainage interfaces to be used is small, the installation space is occupied, affecting the user experience.

[0038] Based on the above application defects of the traditional multi-way pipe joints used at the drainage outlet, the embodiment of the utility model proposes a drainage module, which can be transformed according to the actual drainage interface requirements to be compatible with the use of different scenarios, and when the required drainage interface requirements are small, it can achieve the effect of reducing the installation space occupied.

[0039] The drainage module of this embodiment is used to be installed at the drainage outlet for connection of the drainage pipe of the equipment. The sewage discharged from the drainage pipe is discharged into the drainage outlet through the drainage module. According to different application scenarios, the drainage outlet may include the outlet of the drainage straight pipe, the water outlet of the floor drain (drainage device connected to the drainage pipe system on the ground), etc. That is, the drainage module can be adapted to be installed at the drainage outlet of the drainage straight pipe, the floor drain, etc. to assist the equipment in drainage.

[0040] The bottom pipe 100 is used as a basic component of the drainage module, and is used to be detachably connected to the drainage outlet when the drainage module is installed at the drainage outlet, such as plug-in docking. The bottom pipe 100 is provided with a drainage channel, and when the bottom pipe 100 is plugged into the drainage outlet, the drainage channel is connected to the drainage outlet accordingly. The bottom pipe 100 can be made of a variety of materials, such as three types of polypropylene (PPR, polypropylene random), etc., and this embodiment does not limit this.

[0041] As an extension component of the drainage module, at least one adapter pipe 200 is provided. At least one adapter pipe 200 is detachably connected to the bottom pipe 100, and the forms in which the adapter pipe 200 is detachably connected to the bottom pipe 100 include threaded connection, snap-on connection, etc. As an example, the butt end of one of the adapter pipe 200 and the bottom pipe 100 is provided with an internal thread, and the butt end of the other is provided with an external thread. The adapter pipe 200 and the bottom pipe 100 are connected to each other and threadedly matched with the internal thread and the external thread to achieve a detachable connection. Among them, the pipe body material of the adapter pipe 200 can be a variety of materials, such as type III polypropylene (PPR, polypropylenerandom), etc., which is not limited in this embodiment.

[0042] Specifically, one or more adapter tubes 200 may be provided, such as two or three. When one adapter tube 200 is provided, the adapter tube 200 is detachably connected to the bottom tube 100; when more than one adapter tube 200 is provided, the multiple adapter tubes 200 are detachably connected in sequence, and the adapter tube 200 located at the end position is detachably connected to the bottom tube 100. The form in which any two adapter tubes 200 are detachably connected includes threaded connection, snap-on connection, etc. As an example, the butt end of one of the two adapter tubes 200 is provided with an internal thread, and the butt end of the other of the two adapter tubes 200 is provided with an external thread. The two adapter tubes 200 are connected to each other and threadedly matched with the internal thread and the external thread to achieve a detachable connection. In addition, when more than one adapter tube 200 is provided, the user can increase or decrease the number of adapter tubes 200 assembled on the bottom tube 100 according to actual conditions. In practical applications, when at least one adapter pipe 200 of the drainage module is completely removed, the drainage pipe of the equipment can also be directly connected to the bottom pipe 100 to communicate with the drainage channel of the bottom pipe 100 for drainage.

[0043] In addition, for a plurality of adapter tubes 200, some adapter tubes 200 may have the same tube body type, and other adapter tubes 200 may have different tube body types, or all adapter tubes 200 may have different tube body types, or all adapter tubes 200 may have the same tube body type. The tube body type involves the tube body length, shape structure, etc.

[0044] The adapter pipe 200 is provided with a water inlet channel and at least one adapter pipe is provided with at least two connection ports L, the connection port L is connected to the water inlet channel, when at least one adapter pipe 200 is connected to the bottom pipe 100, the water inlet channel is correspondingly connected to the drainage channel, that is, the connection port L, the water inlet channel, and the drainage channel are connected in sequence. When there is one adapter pipe 200, at least two connection ports L are located on the adapter pipe 200; when there are multiple adapter pipes 200, at least two connection ports L can be respectively provided on multiple adapter pipes 200.

[0045] Specifically, two or more connection ports L may be provided, such as three or four. The connection port L is used for connecting the drainage pipe of the device. When the drainage pipe of the device is connected to the connection port L of the adapter pipe 200, it can be connected to the water inlet channel through the connection port L. The connection port L can be of various types, such as a threaded interface, a snap-on interface, etc., without limitation. Moreover, the types of the connection ports L may be the same or different, and may be provided according to actual conditions.

[0046] Specifically, the drainage pipe of the equipment can be connected to the connection port L on the adapter pipe 200, and the sewage discharged from the drainage pipe can flow into the water inlet channel through the connection port L of the adapter pipe 200, and then flow into the drainage channel of the bottom pipe 100 through the water inlet channel, and then be discharged into the drainage port. The user can connect part of the adapter pipes 200 or all of the adapter pipes 200 of at least one adapter pipe 200 in the drainage module to the bottom pipe 100 according to the actual connection port L requirements. The adapter pipe 200 is provided with at least two connection ports L, which can reduce the number of adapter pipes 200 under the same number of drainage interfaces, and when the number of connection ports L required to be used is small, the user can remove part of the adapter pipes 200 or all of the adapter pipes 200 of at least one adapter pipe 200 in the drainage module according to the actual connection port L requirements, thereby reducing the installation space occupied, thereby achieving the purpose of flexibly adjusting the drainage module according to the number of drainage interfaces required to be used.

[0047] In some embodiments, reference Figure 2 At least one adapter pipe 200 includes a first adapter pipe 210, and the bottom pipe 100 includes a connection inlet; the first end of the first adapter pipe 210 can be connected to the connection inlet, and the second end of the first adapter pipe 210 is provided with at least two connection ports L.

[0048] In this embodiment, at least one adapter pipe 200 adopts a first adapter pipe 210, and the first adapter pipe 210 is detachably connected to the bottom pipe 100. The connection inlet of the bottom pipe 100 is located at one end thereof and is connected to the drainage channel. The first adapter pipe 210 is a cap-shaped structure, having a first end and a second end opposite to each other. The first end of the first adapter pipe 210 can be connected to the connection inlet of the bottom pipe 100, and the end surface of the second end of the first adapter pipe 210 has at least two connection ports L of different calibers. According to the actual use requirements of the connection port L, the user can connect the first adapter pipe 210 to the bottom pipe 100, and then connect the drainage pipe of the equipment to the connection port L of the first adapter pipe 210 with a matching caliber, and then connect it to the drainage module. If the connection port L on the first adapter pipe 210 is not needed, the user can remove the first adapter pipe 210 from the bottom pipe 100 to reduce the installation space occupied.

[0049] In some embodiments, reference Figure 1 and Figure 3At least one adapter pipe 200 includes a first adapter pipe 210 and a second adapter pipe 220. The bottom pipe 100, the second adapter pipe 220 and the first adapter pipe 210 are detachably connected in sequence, and the bottom pipe 100 includes a connection inlet.

[0050] The first end of the second adapter tube 220 can be connected to the connection inlet, the second end of the second adapter tube 220 is connected to the first end of the first adapter tube 210, the second end of the first adapter tube 210 is provided with at least two connection ports L of different calibers, and a connecting tube 221 is provided between the first end of the second adapter tube 220 and the second end of the second adapter tube 220, and the connecting tube 221 is provided with at least one connection port L.

[0051] In this embodiment, at least one adapter pipe 200 includes a first adapter pipe 210 and a second adapter pipe 220, and the bottom pipe 100, the second adapter pipe 220 and the first adapter pipe 210 are detachably connected in sequence. The connection inlet of the bottom pipe 100 is located at one end thereof and is connected to the drainage channel. The first adapter pipe 210 is a cap-shaped structure, having a first end and a second end opposite to each other. The second adapter pipe 220 is a tubular structure, also having a first end and a second end opposite to each other. The first end of the second adapter pipe 220 can be connected to the connection inlet of the bottom pipe 100, and the second end of the second adapter pipe 220 can be connected to the first end of the first adapter pipe 210. The end surface of the second end of the first adapter pipe 210 has at least two connection ports L of different calibers. In addition, a connection pipe 221 is further provided on the side wall of the second adapter pipe 220, one end of which is integrally formed with the second adapter pipe 220 or detachably connected, and at least one connection port L provided on the connection pipe 221 is located at the other end of the connection pipe 221.

[0052] According to the actual use requirements of the connection port L, the user can connect the bottom pipe 100, the second adapter pipe 220, and the first adapter pipe 210 in sequence, and then connect the drainage pipe of the equipment to the connection port L of the first adapter pipe 210 or the connection pipe 221 of the second adapter pipe 220 with a matching diameter according to the type of drainage pipe of the equipment, and then connect it to the drainage module. Optionally, the connection pipe 221 and the second adapter pipe 220 are arranged at an acute angle, and one end of the connection pipe 221 formed with the connection port L extends upward. When the drainage pipe is connected to the connection port L of the connection pipe 221, drainage is convenient, sewage backflow can be avoided, and it is conducive to smooth drainage of the drainage pipe. Exemplarily, the connection port L on the first adapter pipe 210 is a small flow interface, which is used to connect the drainage pipe of small and medium-sized equipment such as the base station of the cleaning equipment; the connection port L on the connection pipe 221 of the second adapter pipe 220 is a large flow interface, which is used to connect the drainage pipe of large equipment such as washing machines.

[0053] The drainage module of this embodiment has a variety of assembly forms, which can be switched by the user. Figure 1As shown, the bottom pipe 100, the second adapter pipe 220 and the first adapter pipe 210 are detachably connected in sequence, and the drainage module is in the assembly form 1 at this time; if the connection port L on the second adapter pipe 220 is not needed, as shown in FIG. Figure 2 As shown, by disassembling the second adapter tube 220 and detachably connecting the first adapter tube 210 to the bottom tube 100, the drainage module is switched from assembly form one to assembly form two; if the connection port L on the first adapter tube 210 is not needed, by disassembling the first adapter tube 210, the second adapter tube 220 remains detachably connected to the bottom tube 100, so that the drainage module is switched from assembly form one to assembly form three, and the second end of the second adapter tube 220 is connected to the drainage pipe of the equipment as the connection port L; if the connection port L on the first adapter tube 210 and the second adapter tube 220 is not needed, by disassembling the first adapter tube 210 and the second adapter tube 220, only the bottom tube 100 is retained, so that the drainage module is switched from assembly form one to assembly form four, and at this time, the connection inlet of the bottom tube 100 is directly connected to the drainage pipe of the equipment.

[0054] In some embodiments, the calibers of at least two connection ports L are different from each other. In practical application, according to the size of the drain pipe of the device, a connection port L with a caliber matching the connection port L can be selected from at least two connection ports L to connect to the drain pipe of the device. In this way, at least two connection ports L can be used to adapt at least two devices with different drain pipe sizes (such as washing machines, base stations of cleaning equipment, etc.) to connect, realize interface diversity, and expand the interface size that the drain pipe of the device can be connected to. Alternatively, the caliber of at least one connection port L is adjustable, that is, in practical application, the caliber of the connection port L can be adjusted according to the size of the drain pipe of the device so that it can be adapted and connected to the drain pipe of the device. As an example, a connector is detachably provided at the connection port L with adjustable caliber, and is connected to the drain pipe of the device through the connector. For the connection port L with adjustable caliber, multiple connectors that can be detachably connected to it are configured, and the calibers of the multiple connectors are different. Therefore, according to the size of the drain pipe of the device, a connector with a caliber matching the connection port L can be selected from multiple connectors and installed at the connection port L, and then the caliber of the connection port L is adjusted to adapt and connect with the drain pipe of the device. Of course, this is merely exemplary and not restrictive, and includes but is not limited to this.

[0055] In some embodiments, reference Figures 1 to 3, based on the design that the calibers of at least two connection ports L are different from each other or the caliber of at least one connection port L is adjustable, at least two connection ports L of different calibers provided at the second end of the first adapter pipe 210 are arranged around the central axis of the first adapter pipe 210. In this embodiment, at least two connection ports L of different calibers are arranged around the central axis of the first adapter pipe 210, that is, at least two connection ports L of different calibers are arranged in sequence on the circumference of the first adapter pipe 210. For the drain pipes of multiple devices assembled with the drainage module, when the drain pipes are connected to the connection ports L adapted to their calibers, they can be extended outward from the position of the connection ports L, which can avoid interference between the drain pipes and facilitate the placement and disassembly of the drain pipes.

[0056] In some embodiments, reference Figure 1 and Figure 3 , the connecting pipe 221 is also provided with a fixing sleeve 222 located in its connecting port L for inserting the drainage pipe. In this embodiment, the fixing sleeve 222 is installed in the connecting port L of the connecting pipe 221, and the fixing sleeve 222 has a socket adapted to the drainage pipe. Exemplarily, the fixing sleeve 222 is made of one of plastic material, rubber material, metal material, and composite material. The user can directly insert the drainage pipe into the socket of the fixing sleeve 222, and then connect the drainage pipe to the connecting port L. The fixing sleeve 222 has a fixing effect on the drainage pipe. Through the fixing sleeve 222, the drainage pipe is stably connected to the connecting port L, which can improve the connection stability of the drainage pipe and prevent the drainage pipe from detaching from the connecting port L of the connecting pipe 221. In addition, the fixing sleeve 222 forms a seal between the drainage pipe and the connecting port L, which can avoid water leakage during the drainage process.

[0057] In some embodiments, reference Figure 3 The outer wall of the fixing sleeve 222 is configured with a plurality of first annular abutting portions 1A sequentially arranged along the axial direction of the fixing sleeve 222. The first annular abutting portions 1A are used to elastically abut against the inner wall of the connecting pipe 221. Specifically, when the drainage pipe of the equipment is inserted into the socket of the fixing sleeve 222, the fixing sleeve 222 is squeezed and expanded to match the inner diameter of the connecting pipe 221. The plurality of first annular abutting portions 1A on the outer wall of the fixing sleeve 222 elastically abut against the inner wall of the connecting pipe 221, and then expand in the connecting pipe 221 to fix and lock the drainage pipe. Among them, the number of the first annular abutting portions 1A can be set according to actual conditions, and this embodiment does not limit this.

[0058] In some embodiments, reference Figure 3The outer wall of the fixing sleeve 222 is provided with a first limiting portion 1B extending in the radial direction of the fixing sleeve 222, and the first limiting portion 1B abuts against the edge of the pipe opening of the connecting pipe 221 along the axial direction of the connecting pipe 221. Exemplarily, the first limiting portion 1B is arranged in an annular shape along the outer wall of the fixing sleeve 222. When the fixing sleeve 222 is installed in the connecting port L of the connecting pipe 221, the first limiting portion 1B abuts against the edge of the pipe opening of the connecting pipe 221 to limit the installation of the fixing sleeve 222, so that the user can conveniently extract the fixing sleeve 222, and avoid the fixing sleeve 222 being completely sunk into the connecting port L to affect the disassembly.

[0059] In some embodiments, the outer wall of the fixing sleeve 222 is configured with a plurality of first annular abutting portions 1A sequentially arranged along the axial direction of the fixing sleeve 222, and the first annular abutting portions 1A are used to elastically abut against the inner wall of the connecting tube 221. The outer wall of the fixing sleeve 222 is configured with a first limiting portion 1B extending along the radial direction of the fixing sleeve 222, and the first limiting portion 1B abuts against the edge of the pipe opening of the connecting tube 221 along the axial direction of the connecting tube 221.

[0060] In some embodiments, reference Figure 3 , a first step T1 is constructed on the outer wall of the second end of the second adapter tube 220, and a first seal 1 sleeved on the second adapter tube 220 is placed on the first step T1. The first seal 1 is used to seal the gap between the outer wall of the second adapter tube 220 and the inner wall of the first adapter tube 210. Exemplarily, the first seal 1 includes a first sealing ring, and the first sealing ring is adapted to the outer diameter of the second adapter tube 220. When the first end of the first adapter tube 210 is connected to the second end of the second adapter tube 220, the first end of the first adapter tube 210 can be abutted against the first step T1, and the first seal 1 is between the outer wall of the second adapter tube 220 and the inner wall of the first adapter tube 210 to seal the gap between the outer wall of the second adapter tube 220 and the inner wall of the first adapter tube 210 to prevent water leakage and dirtying the ground.

[0061] In some embodiments, reference Figure 3 A second step T2 is constructed on the outer wall of the bottom pipe 100 at the location of the connection inlet, and a second seal 2 is placed on the second step T2. The second seal 2 is used to seal the gap between the outer wall of the bottom pipe 100 and the inner wall of the second adapter pipe 220. Exemplarily, the second seal 2 is a second sealing ring, and the second sealing ring is adapted to the outer diameter of the bottom pipe 100. When the first end of the second adapter pipe 220 is connected to the connection inlet of the bottom pipe 100, the first end of the second adapter pipe 220 can be abutted against the second step T2, and the second seal 2 is between the outer wall of the bottom pipe 100 and the inner wall of the second adapter pipe 220 to seal the gap between the outer wall of the bottom pipe 100 and the inner wall of the second adapter pipe 220 to prevent water leakage and dirtying the ground.

[0062] In some embodiments, a first step T1 is constructed on the outer wall of the second end of the second adapter tube 220, and a first seal 1 sleeved on the second adapter tube 220 is placed on the first step T1. The first seal 1 is used to seal the gap between the outer wall of the second adapter tube 220 and the inner wall of the first adapter tube 210, and a second step T2 is constructed on the outer wall at the connection entrance of the bottom tube 100, and a second seal 2 sleeved on the bottom tube 100 is placed on the second step T2. The second seal 2 is used to seal the gap between the outer wall of the bottom tube 100 and the inner wall of the second adapter tube 220.

[0063] In some embodiments, reference Figure 3 The bottom pipe 100 includes a connecting section 110, a guide section 120 and an insertion section 130 which are sequentially arranged along the length direction of the bottom pipe 100. The connecting section 110 is configured with a connecting inlet. The guide section 120 is used to guide the water flow of the connecting section 110 to the insertion section 130. The insertion section 130 is used to be inserted and matched with the drain outlet when the drainage module is installed at the drain outlet.

[0064] The bottom pipe 100 is divided into a connecting section 110, a diversion section 120 and an inserting section 130. The connecting section 110, the diversion section 120 and the inserting section 130 are sequentially arranged along the length direction of the bottom pipe 100. The drainage channel of the bottom pipe 100 passes through the connecting section 110, the diversion section 120 and the inserting section 130. The length of each section can be set according to actual conditions. Optionally, the length of the connecting section 110 is less than the length of the diversion section 120, and the length of the diversion section 120 is less than the length of the inserting section 130.

[0065] The connecting section 110 is configured with a connecting inlet for connecting with the first adapter tube 210 or the second adapter tube 220. For example, the bottom tube 100 is provided with an external thread on the outer wall of the connecting section 110, and the first end of the first adapter tube 210 or the first end of the second adapter tube 220 is provided with an internal thread, and the first end of the first adapter tube 210 or the first end of the second adapter tube 220 is connected to the connecting section 110 of the bottom tube 100 and threadedly matched with the external thread through the internal thread to achieve a detachable connection.

[0066] The insertion section 130 is used to be inserted into the drain port when the drainage module is installed to fix the drainage module. The outer diameter of the insertion section 130 is smaller than the diameter of the drain port. The diversion section 120 is located between the connection section 110 and the insertion section 130. The water flow of the connection section 110 passes through the diversion section 120 to be guided into the insertion section 130, thereby achieving smooth flow of water in the bottom pipe 100.

[0067] In some embodiments, reference Figure 3, the inner diameter of the guide section 120 is gradually changed from large to small along the water flow direction; and / or, the outer diameter of the guide section 120 is gradually changed from large to small along the water flow direction.

[0068] In this embodiment, the inner diameter size of the guide section 120 can be set to gradually change from large to small along the direction of water flow, that is, along the direction of water flow in the drainage pipe of the bottom pipe 100, the inner diameter size of the guide section 120 gradually decreases, and the water flow flows along the inner wall of the guide section 120 to be guided and accelerated to flow to the insertion section 130, which helps to speed up the drainage speed and improve the drainage efficiency.

[0069] The outer diameter of the diversion section 120 can be set to gradually change from large to small along the direction of water flow, that is, along the direction of water flow in the drainage pipe of the bottom pipe 100, the outer diameter of the diversion section 120 gradually decreases. When the drainage module is installed at the drain outlet, the insertion section 130 is inserted into the drain outlet, and a drainage space is formed between the diversion section 120 and the ground around the drain outlet. The flowing water on the ground can flow into the drain outlet through the drainage space, so that equipment drainage and ground drainage can be carried out simultaneously, and the ground drainage function is kept intact.

[0070] In some embodiments, reference Figure 4 and Figure 5 The drainage module further includes a mounting sleeve 300, which is used to be detachably mounted on the insertion section 130 of the bottom pipe 100, and the insertion section 130 is mounted in the drainage port through the mounting sleeve 300. In this embodiment, the mounting sleeve 300 is compatible with the insertion section 130 of the bottom pipe 100, and the user can mount the mounting sleeve 300 on the insertion section 130 of the bottom pipe 100, and then insert the insertion section 130 of the bottom pipe 100 into the drainage port. Under the tightening action of the mounting sleeve 300, the insertion section 130 of the bottom pipe 100 is stably inserted into the drainage port, which can improve the installation stability of the drainage module and prevent the drainage module from being separated from the drainage port.

[0071] In some embodiments, reference Figure 4 and Figure 5The mounting sleeve 300 includes a first mounting sleeve 310 and a second mounting sleeve 320, and the first mounting sleeve 310 and the second mounting sleeve 320 can be selectively installed on the insertion section 130. In this embodiment, optionally, the first mounting sleeve 310 and the second mounting sleeve 320 have different structural types, and the two can be used to adapt to the same type of drain outlets, and can also be used to adapt to different types of drain outlets to install the drainage module. Among them, the material of the first mounting sleeve 310 and the second mounting sleeve 320 can be selected according to actual conditions, such as plastic material. The user can select the first mounting sleeve 310 or the second mounting sleeve 320 for installation and use according to the actual type of drain outlet, which can adapt to a variety of application scenarios. For example, when the type of the drain outlet is a first type of drain outlet (such as a floor drain type drain outlet), the drainage module can use a first mounting sleeve 310 to be installed on the insertion section 130 of the bottom pipe 100, so as to be installed on the first type of drain outlet through the first mounting sleeve 310; when the type of the drain outlet is a second type of drain outlet (such as a straight drainage pipe type drain outlet), the drainage module can use a second mounting sleeve 320 to be installed on the insertion section 130 of the bottom pipe 100, so as to be installed on the second type of drain outlet through the second mounting seat.

[0072] In some embodiments, reference Figure 4 The outer wall of the first mounting sleeve 310 is constructed with a plurality of snap-fitting parts 311 arranged along the circumference of the first mounting sleeve 310, and the snap-fitting part 311 has a first snap-fitting protrusion 3111 and a second snap-fitting protrusion 3112 arranged along the axial direction of the first mounting sleeve 310 at intervals. The first mounting sleeve 310 can be adapted to a drainage outlet of a floor drain type, including but not limited to this. Specifically, the floor drain includes a funnel-shaped shell and a grille cover plate covered on the funnel-shaped shell, a pipe opening is provided on the grille cover plate, and a water outlet is constructed at the bottom of the funnel-shaped shell. When the drainage module is installed at the floor drain, the insertion section 130 of the bottom pipe 100 passes through the pipe opening and is inserted into the water outlet or passes through the pipe opening and corresponds to the position of the water outlet. Exemplarily, the first mounting sleeve 310 is located on the lower side of the grille cover and passes through the water outlet along with the insertion section 130 of the bottom pipe 100. The first locking protrusion 3111 of the locking portion 311 constructed on the outer wall of the first mounting sleeve 310 is located on the upper side of the funnel-shaped shell, and the second locking protrusion 3112 is located on the lower side of the funnel-shaped shell. The top surface and the bottom surface of the funnel-shaped shell respectively constitute movement limits for the first locking protrusion 3111 and the second locking protrusion 3112 of the locking portion 311 within a certain range, thereby limiting the installation of the first mounting sleeve 310 and the bottom pipe 100 to achieve adaptive installation of the drainage module and the floor drain.

[0073] In some embodiments, reference Figure 5The outer wall of the second mounting sleeve 320 is constructed with a plurality of second annular abutting portions 2A arranged in sequence along the axial direction of the second mounting sleeve 320, and the second annular abutting portions 2A are used to elastically abut against the inner wall of the drain outlet. The second mounting sleeve 320 can be adapted to drain outlets of the drainage straight pipe type, including but not limited to this. Specifically, when the second mounting sleeve 320 is inserted into the drainage straight pipe along with the insertion section 130 of the bottom pipe 100, the second mounting sleeve 320 elastically expands to match the inner diameter of the drainage straight pipe, and the plurality of second annular abutting portions 2A on the outer wall of the second mounting sleeve 320 elastically abut against the inner wall of the drainage straight pipe, and then expand and tighten in the drainage straight pipe to fix and lock the bottom pipe 100. Among them, the number of the second annular abutting portions 2A can be set according to actual conditions, and this embodiment does not limit this.

[0074] In some embodiments, reference Figure 5 , a second limiting portion 2B extending radially along the second mounting sleeve 320 is constructed on the outer wall of the second mounting sleeve 320. Optionally, the second limiting portion 2B is arranged in a ring shape along the outer wall of the second mounting sleeve 320. When the second mounting sleeve 320 is inserted into the drainage straight pipe along with the insertion section 130 of the bottom pipe 100, the second limiting portion 2B can be correspondingly abutted against the edge of the pipe mouth of the drainage straight pipe to insert and limit the second mounting sleeve 320 and the bottom pipe 100, so that the user can easily extract the second mounting sleeve 320, and the second mounting sleeve 320 can be prevented from being completely sunk into the pipe mouth of the drainage straight pipe and affecting the disassembly. In addition, the second limiting portion 2B also forms a seal for the gap between the second mounting sleeve 320 and the edge of the pipe mouth of the drainage straight pipe to prevent water leakage from dirtying the ground.

[0075] In some embodiments, the outer wall of the first mounting sleeve 310 is constructed with a plurality of snap-fitting portions 311 arranged along the circumference of the first mounting sleeve 310, the snap-fitting portions 311 have a first snap-fitting protrusion 3111 and a second snap-fitting protrusion 3112 arranged at intervals along the axial direction of the first mounting sleeve 310, and the outer wall of the second mounting sleeve 320 is constructed with a plurality of second annular supporting portions 2A arranged in sequence along the axial direction of the second mounting sleeve 320, and the second annular supporting portions 2A are used to elastically support the inner wall of the drain outlet.
