[0031] Referring to Figs. 1-3 The utility model discloses a pipeline pump, including: casing 10, motor 20 and impeller 30, the both ends of casing 10 are equipped with water inlet end 11 and water outlet end 12 respectively, the motor 20 sets up in the outside of casing 10, the impeller 30 sets up in the inside of casing 10, and the impeller 30 drive connection is in motor 20, the motor 20 work drives the rotation of impeller 30, to form suction and make water flow along water inlet end 11 enter casing 10, and along water outlet end 12 flow out.

[0032] Specifically, by motor 20 drive impeller 30 rotation, form powerful suction, effectively guide water flow from water inlet end 11 enter casing 10 inside, and accelerate through water outlet end 12 and discharge, this design significantly enhances the water pressure lifting capacity of pipeline pump, so that intelligent toilet can keep stable flushing effect even in low water pressure environment, greatly improve the adaptability of product.

In addition, the transmission connection design of motor 20 and impeller 30 ensures the efficiency and stability of power transmission, reduces energy loss and mechanical wear and tear, in addition, the both ends of casing 10 are equipped with water inlet end 11 and water outlet end 12 respectively, optimize the water flow path, reduce the water flow resistance, improve the working efficiency of pump, these designs collectively improve the overall performance and reliability of pipeline pump, prolong the service life.

[0033] Referring to Figs. 1-3 As shown in the figure, in an embodiment, the impeller 30 is connected with a transmission shaft 40, and the end of the transmission shaft 40 away from the impeller 30 is drivingly connected to the output shaft of the motor 20 through a connecting piece 50.

[0034] Specifically, the central hole of the impeller 30 is designed with an internal thread or a key groove matching the transmission shaft 40, to ensure that the impeller 30 can be firmly fixed on the transmission shaft 40. The end of the transmission shaft 40 (i.e. the end close to the impeller 30) is processed into an external thread or a keyed shape matching the central hole of the impeller 30, so as to be tightly connected with the impeller 30. The end of the transmission shaft 40 away from the impeller 30 is designed with a connecting piece 50 mounting hole or a flange, for mounting the connecting piece 50. The connecting piece 50 usually takes the form of a coupling, a universal joint or an elastic sleeve, etc., to adapt to the slight deviation and angular change between the transmission shaft 40 and the output shaft of the motor 20. The end of the output shaft of the motor 20 is also designed into a shape matching the connecting piece 50, so as to realize driving connection with the transmission shaft 40 through the connecting piece 50. During installation, the connecting piece 50 is sleeved on the transmission shaft 40 and the output shaft of the motor 20, and the two are firmly connected together through bolts, pins and other fasteners.

[0035] That is, the tight connection between the impeller 30 and the transmission shaft 40, and between the transmission shaft 40 and the output shaft of the motor 20, ensures the high efficiency of power transmission, reduces the loss of energy in the transmission process, and improves the working efficiency of the pipeline pump. In addition, by using internal thread, key groove, coupling and other connection methods, the firm connection between the impeller 30, the transmission shaft 40 and the output shaft of the motor 20 is ensured, and the stability of this structure helps to reduce vibration and noise, prolonging the service life of the pipeline pump. In addition, the design of the connecting piece 50 allows a certain deviation and angular change between the transmission shaft 40 and the output shaft of the motor 20, and this adaptability makes the pipeline pump flexible in response to different installation environments and equipment requirements during installation.

[0036] In an embodiment, the connecting piece 50 is a coupling.

[0037] Specifically, according to the working conditions, transmission power and speed requirements of the pipeline pump, the appropriate type of coupling is selected. Common types of couplings include diaphragm couplings, elastic pin couplings, plum couplings, etc. In this pipeline pump, a diaphragm coupling is preferred, as it has the advantages of compact structure, high transmission efficiency and strong compensation ability. In addition, the coupling is designed with elastic elements (such as diaphragm, elastic pin, etc.), which can compensate for the deviation and angular change between the transmission shaft 40 and the output shaft of the motor 20 due to manufacturing errors, installation errors or thermal expansion during operation, etc. This compensation ability ensures the stable operation of the pipeline pump under complex working conditions.

[0038] That is, the coupling can accurately transmit torque while allowing a certain degree of deviation and angular change between the two shafts, which improves the transmission accuracy and stability of the pipeline pump and reduces vibration and noise. In addition, the deviation compensation capability of the coupling allows the pipeline pump to flexibly respond to different installation environments and equipment requirements during installation. Even if there is a slight misalignment or angular deviation between the transmission shaft 40 and the motor 20 output shaft, the coupling can effectively transmit power to ensure normal operation of the pipeline pump.

[0039] Referring to Fig. 2 As shown in an embodiment, a sealing member 60 is further provided between the transmission shaft 40 and the housing 10.

[0040] Specifically, the end of the transmission shaft 40 away from the impeller 30 protrudes out of the housing 10 and is connected to the coupling. A sealing member 60 is provided at the connection between the transmission shaft 40 and the housing 10. The provision of the sealing member 60 effectively prevents water leakage from the gap between the transmission shaft 40 and the housing 10, ensuring the normal operation of the pipeline pump and the cleanliness of the surrounding environment. In addition, the use of high-precision sealing member 60 improves the sealing performance between the transmission shaft 40 and the housing 10. Even in high-pressure, high-temperature or corrosive medium environments, good sealing effect can be maintained.

[0041] Referring to Fig. 3 As shown in an embodiment, the water inlet end 11 is connected with a water inlet fixed pipe 70.

[0042] Specifically, by connecting the water inlet fixed pipe 70 to the water inlet end 11, the noise caused by the operation of the pipeline pump can be effectively reduced.

[0043] Referring to Fig. 3 As shown in an embodiment, the water inlet fixed pipe 70 is connected to a water tank 80.

[0044] Specifically, the water inlet fixed pipe 70 is directly connected to the water outlet of the water tank 80 or the drain valve at the bottom, which is a simple and direct connection method suitable for scenarios where the water tank 80 is located lower or the system pressure requirement is not high. In some applications with higher requirements for water quality, a filter may be provided between the water inlet fixed pipe 70 and the water tank 80. The filter can intercept impurities and particulate matter in the water to protect subsequent equipment from damage.

[0045] Referring to Figs. 1-3 As shown in an embodiment, the water outlet end 12 includes a first water outlet 121 and a second water outlet 122, and the first water outlet 124 is connected with a water outlet fixed pipe 90.

[0046] Specifically, by providing multiple water outlets, water flow can be distributed to different downstream devices or systems according to actual needs, thereby improving the efficiency and flexibility of water flow transmission. In addition, the design of multiple water outlets enables the device to simultaneously meet different water flow output requirements. For example, in an intelligent toilet system, one water outlet can be used for flushing the toilet bowl surface, while another water outlet can be used to cause siphon at the toilet water seal position. In addition, the provision of the water outlet fixed pipe 90 can effectively reduce the noise caused by the operation of the pipeline pump.

[0047] Referring to Fig. 3 In an embodiment, the water outlet fixed pipe 90 is connected to the flushing pipe 100.

[0048] Specifically, the water outlet fixed pipe 90 is connected to the flushing pipe 100. This connection can be direct or indirect through a connector (such as a joint, a tee, etc.). The flushing pipe 100 is usually designed to cover the inner wall of the toilet ceramic. When the pipeline pump is started, water flow is pumped to the water outlet fixed pipe 90 and sprayed out through the flushing pipe 100 to clean the inner wall of the toilet ceramic.

[0049] That is, through the connection of the water outlet fixed pipe 90 and the flushing pipe 100, accurate spraying and cleaning of the inner wall of the toilet ceramic are achieved, improving the cleaning efficiency and quality.

[0050] In an embodiment, a flow limiting adjusting member (not shown in the figure) is further provided between the water outlet fixed pipe 90 and the flushing pipe 100.

[0051] Specifically, the flow limiting adjusting member can be selected as a flow limiting sheet or a flow limiting valve. The flow limiting sheet is usually a thin sheet with a pre-set aperture, and the flow is controlled by adjusting the size of the aperture. The flow limiting valve is an adjustable valve, and the flow is controlled by rotating the valve handle or adjusting the mechanism inside the valve to change the passage cross-sectional area. The flow limiting adjusting member is installed on the connecting pipeline between the water outlet fixed pipe 90 and the flushing pipe 100. The installation position can be adjusted flexibly according to actual needs, but it should usually be selected at a position that is convenient for observation and operation. When installing, it is necessary to ensure that the sealing between the flow limiting adjusting member and the connecting pipeline is good to prevent water leakage. Connection can be achieved by screw connection, flange connection, etc. During use, the need for adjustment of the flow limiting adjusting member can be determined by observing the spraying effect of the flushing pipe 100. If adjustment is needed, the handle of the flow limiting valve can be rotated or the flow limiting sheet with a different aperture can be replaced according to actual needs. When adjusting, it should be done gradually to avoid sudden changes in flow caused by excessive adjustment at one time, which may affect the cleaning effect or damage the equipment.

[0052] That is, by setting the flow regulating member, it can ensure that the washing pipe 100 gets stable flow output, avoiding the impact on the cleaning effect due to excessive or insufficient flow. In addition, reasonable flow control can make the water flow sprayed by the washing pipe 100 more uniform and powerful, thereby improving the cleaning efficiency and quality. In addition, excessive flow may cause the sprayed water to fly out of the ceramic inner cavity of the toilet, and by setting the flow regulating member, the flow stability of the cleaning water can be effectively ensured.

[0053] In an embodiment, the second water outlet 122 is connected to a spray pipe (not shown in the figure).

[0054] Specifically, the second water outlet 122 is connected to the spray pipe through a connecting pipe or hose, and such connection should ensure good sealing to prevent water leakage. The connection method can be threaded connection, flange connection or other reliable connection method, depending on the size, shape of the water outlet and spray pipe and the requirements of the use environment. The spray pipe is usually designed to be able to spray water flow at a certain speed and direction to the target area. Its length, diameter and spray angle and other parameters should be customized according to actual needs. When the pipe pump is started, the water flow is sent to the second water outlet 122 and sprayed out through the spray pipe at a predetermined speed and direction. The spray intensity, spray time and spray mode and other parameters can be controlled through the control panel or remote control to meet different use requirements.

[0055] That is, through the connection of the second water outlet 122 and the spray pipe, water flow spraying to a specific area is realized, and such design has wide application value in cleaning, cooling, spraying and other applications. In addition, the design of the spray pipe enables the water flow to be sprayed to the target area at a high speed and directionality, thereby improving the spraying efficiency. In addition, by equipping different shapes and sizes of nozzles, the spray shape and spray range of the water flow can be further controlled, thereby enhancing the spraying effect. In addition, the spray intensity, spray time and spray mode and other parameters can be flexibly controlled through the control panel or remote control, so that the equipment can adapt to different use environments and requirements.

[0056] The utility model discloses still disclose a toilet, including the pipeline pump, ceramic body and apron as described above, pipeline pump sets up in ceramic body, apron installs in ceramic body.

[0057] Specifically, by setting a pipeline pump on the toilet bowl, then driving the impeller 30 to rotate through the motor 20, a strong suction force is formed, effectively guiding the water flow from the water inlet end 11 into the inside of the shell 10, and accelerating through the water outlet end 12 to discharge, which significantly enhances the water pressure lifting capacity of the pipeline pump, so that the intelligent toilet can maintain stable flushing effect even in low water pressure environment, greatly improving the adaptability of the product; in addition, the pipeline pump adopts the innovative layout of external motor 20 and internal impeller 30, the motor 20 is arranged outside the shell 10, which not only facilitates the installation, debugging and maintenance of the motor 20, but also reduces the space occupation inside the shell 10, so that the structure of the whole pipeline pump is more compact and integrated, this design simplifies the docking step in the installation process, reduces the skill requirement of the production line workers, thereby effectively shortens the assembly time and improves the production efficiency of the toilet.

[0058] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can be realized in other ways, any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
