Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to an integrated cleaning pump. Background Technology

[0002] Cleaning pumps, which use a driven impeller to pressurize or transfer liquid, are widely used in the circulating cleaning of water tanks. After cleaning, existing cleaning pumps typically require an additional drain pump to be connected to the tank to discharge the wastewater. However, too many connection points not only complicate the pump assembly process and reduce assembly efficiency, but also increase the risk of leakage at the connections and increase the length of the pipe connections, thus increasing manufacturing costs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an integrated cleaning pump.

[0004] The technical solution adopted by this utility model is as follows: An integrated cleaning pump includes a pump casing having a pump chamber and a mounting chamber, wherein a first impeller is disposed inside the pump chamber, and a water outlet pipe communicating with the pump chamber is disposed on the pump casing. The pump casing is also equipped with an integrated pipe that communicates with the pump chamber. The integrated pipe has an inlet, a wastewater outlet, and an installation port. A second impeller is installed inside the integrated pipe. The mounting cavity is equipped with a first drive mechanism that drives the first impeller to rotate, causing fluid to enter the pump cavity from the inlet and exit the pump cavity from the outlet pipe. The mounting port is sealed with a second drive mechanism that drives the second impeller to rotate, causing fluid to flow from the inlet to the wastewater outlet.

[0005] Preferably, the integrated pipe includes an L-shaped pipe section, which is composed of a first pipe section and a second pipe section. The end of the first pipe section away from the second pipe section is the water inlet, and the end of the second pipe section away from the first pipe section is the installation port. The second impeller is installed inside the second pipe section. The integrated pipeline also includes a waste discharge pipe section connected to and communicating with the second pipe section. The end of the waste discharge pipe section away from the second pipe section is a wastewater outlet.

[0006] Preferably, the waste discharge pipe section is provided with a one-way valve assembly, which restricts the flow of fluid in the waste discharge pipe section into the second pipe section.

[0007] Preferably, the one-way valve assembly includes a one-way valve disc. The inner cavity of the waste discharge pipe section, from one end connected to the second pipe section to the wastewater outlet end, includes a first cavity and a second cavity connected to each other. The first cavity is smaller than the second cavity, and a step is formed between them. The one-way valve disc includes a fixed part that is fixed in position relative to the waste discharge pipe and a valve disc part located in the second cavity and having a larger size than the first cavity. The valve disc portion swings relative to the fixed portion, having a first sealing position that engages with the abutting step to prevent communication between the second cavity and the first cavity, and a first flow position that moves away from the abutting step to allow communication between the second cavity and the first cavity.

[0008] Preferably, one end of the wastewater outlet of the wastewater discharge pipe is connected to a wastewater discharge pipe. The waste discharge pipe includes a central pipe section and a connecting ring section surrounding the outer periphery of the central pipe section. One end of the wastewater outlet of the waste discharge pipe section is inserted between and connected to the central pipe section and the connecting ring section. The central tube has a limiting plate extending to the upper end face of the fixing part, and the fixing part is limited between the abutting step and the limiting plate part so that the position of the fixing part relative to the waste discharge tube is fixed.

[0009] Preferably, the fixing part is provided with a positioning hole, and the abutting step is provided with a positioning plate that matches the shape of the positioning hole, and the positioning plate passes through the positioning hole.

[0010] Preferably, the positioning plate and the limiting plate are arranged adjacent to each other.

[0011] Preferably, the waste discharge pipe is located on one circumferential side of the second impeller.

[0012] Preferably, the L-shaped tube is an integrally formed part, and the waste discharge tube is integrally formed on the L-shaped tube.

[0013] Preferably, the pump housing includes a volute and a motor housing with openings facing the same direction. One end of the opening of the volute is connected to the end of the motor housing away from the opening. One end of the opening of the motor housing is connected to an end cap. The integrated pipe and the water outlet pipe are integrally formed on the volute.

[0014] The beneficial effects of this utility model are as follows: This device integrates the waste discharge structure onto the cleaning pump. When the first drive mechanism is turned on, the pump body begins to clean the water tank. After the water tank is cleaned by circulation, the first drive mechanism is turned off and the second drive mechanism is turned on. Wastewater enters the integrated pipe from the inlet and is discharged from the wastewater outlet. It shares a single inlet, which solves the defects of complex pump body assembly process and low efficiency caused by too many connection positions, reduces production and manufacturing costs, and improves the convenience of use and disassembly.

[0020] like Figures 1 to 5 As shown in the figure, an integrated cleaning pump according to an embodiment of the present invention includes a pump casing 1 having a pump chamber 101 and a mounting chamber 102. A first impeller 2 is disposed inside the pump chamber 101, and a water outlet pipe 12 communicating with the pump chamber 101 is disposed on the pump casing 1. The pump casing 1 is also provided with an integrated pipe 11 communicating with the pump chamber 101. The integrated pipe 11 is provided with a water inlet 1111, a wastewater outlet 1131 and an installation port 1121. A second impeller 5 is provided inside the integrated pipe 11. The mounting cavity 102 is equipped with a first drive mechanism 3 that drives the first impeller 2 to rotate, causing fluid to enter the pump cavity 101 from the inlet 1111 and exit the pump cavity 101 from the outlet pipe 12. The mounting port 1121 is sealed with a second drive mechanism 4 that drives the second impeller 5 to rotate, causing the fluid to flow from the inlet 1111 to the wastewater outlet 1131.

[0021] With this setup, the waste discharge structure is integrated into the cleaning pump. When the first drive mechanism is activated, the pump body begins cleaning the water tank. After the water tank is cleaned, the first drive mechanism is deactivated and the second drive mechanism is activated. Wastewater enters the integrated pipe from the inlet and is discharged from the outlet. By sharing a single inlet, the drawbacks of complex pump assembly and low efficiency caused by too many connection points are solved, reducing manufacturing costs and improving ease of use and disassembly.

[0022] In this embodiment, the first drive mechanism 3 is specifically a brushless motor, including a stator and a rotor, and the second drive mechanism 4 is specifically a rotary motor.

[0023] The integrated pipe 11 includes an L-shaped pipe section, which is composed of a first pipe section 111 and a second pipe section 112. The end of the first pipe section 111 away from the second pipe section 112 is the water inlet 1111, and the end of the second pipe section 112 away from the first pipe section 111 is the installation port 1121. The second impeller 5 is installed inside the second pipe section 112. The integrated pipe 11 also includes a waste discharge pipe section 113 connected to and communicating with the second pipe section 112. The end of the waste discharge pipe section 113 away from the second pipe section 112 is a wastewater outlet 1131.

[0024] This design not only simplifies the structure of the integrated cleaning pump but also ensures stable cleaning and waste removal performance.

[0025] The waste discharge pipe section 113 is provided with a one-way valve assembly, which restricts the flow of fluid in the waste discharge pipe section 113 into the second pipe section 112.

[0026] This design prevents waste liquid entering the waste discharge pipe from flowing back into the second pipe section, thus avoiding waste liquid residue and facilitating complete waste liquid discharge.

[0027] The one-way valve assembly includes a one-way valve disc 6. The inner cavity of the waste discharge pipe section 113, from one end connected to the second pipe section 112 to the wastewater outlet 1131, includes a first cavity section 1132 and a second cavity section 1133 connected to each other. The first cavity section 1132 is smaller than the second cavity section 1133, and an abutting step 1134 is formed between the two. The one-way valve disc 6 includes a fixing part 61 that is fixed relative to the waste discharge pipe part 113 and a valve disc part 62 located in the second cavity part 1133 and having a larger size than the first cavity part 1132. The valve disc portion 62 swings relative to the fixed portion 61 to have a first sealing position that is in contact with the abutting step 1134 to prevent the second cavity portion 1133 from communicating with the first cavity portion 1132, and a first flow position that is away from the abutting step 1134 and allows the second cavity portion 1133 to communicate with the first cavity portion 1132.

[0028] With this setting, when waste liquid flows into the first chamber, the pressure in the first chamber is greater than that in the second chamber, and the valve flap swings to the first flow position, allowing the waste liquid to enter the second chamber and flow out from the wastewater outlet. When there is waste liquid in the second chamber or no waste liquid in the first chamber, the pressure in the first chamber is less than that in the second chamber, and the valve flap is in the first sealing position.

[0029] One end of the wastewater outlet 1131 of the wastewater discharge pipe section 113 is connected to the wastewater discharge pipe 7. The waste discharge pipe 7 includes a central pipe section 71 and a connecting ring section 72 surrounding the outer periphery of the central pipe section 71. One end of the wastewater outlet 1131 of the waste discharge pipe section 113 is inserted between and connected to the central pipe section 71 and the connecting ring section 72. The central tube 71 has a limiting plate 711 extending to the upper end face of the fixing part 61. The fixing part 61 is limited between the abutting step 1134 and the limiting plate 711, so that the fixing part 61 is fixed relative to the waste discharge tube 113.

[0030] This design makes it easy to assemble the waste discharge pipe and the waste discharge pipe section, and after assembly, it automatically fixes the one-way valve disc.

[0031] The fixing part 61 is provided with a positioning hole 611, and the abutting step 1134 is provided with a positioning plate 1135 that is adapted to the shape of the positioning hole 611, and the positioning plate 1135 passes through the positioning hole 611.

[0032] With this setting, during the assembly process, the positioning plate is inserted into the positioning hole to position the one-way valve disc, making it less likely for the one-way valve disc to shift during the insertion of the waste discharge pipe and during the waste discharge process.

[0033] The positioning plate 1135 and the limiting plate portion 711 are disposed adjacent to each other.

[0034] With this setting, the positioning plate is positioned circumferentially during the insertion of the waste pipe, making it less prone to circumferential displacement.

[0035] The waste discharge pipe section 113 is located on one circumferential side of the second impeller 5.

[0036] With this setup, the waste liquid is directly thrown into the waste discharge pipe section by the centrifugal force generated by the rotation of the second impeller, reducing the path of the waste liquid into the waste discharge pipe section.

[0037] The L-shaped tube section is an integrally formed part, and the waste discharge tube section 113 is integrally formed on the L-shaped tube section.

[0038] This design reduces assembly steps and potential leakage points, ensuring the pump's sealing performance and operational safety.

[0039] The pump housing 1 includes a volute 13 and a motor housing 14 with openings facing the same direction. One end of the opening of the volute 13 is connected to the end of the motor housing 14 away from the opening. One end of the opening of the motor housing 14 is connected to an end cap 15. The integrated pipe 11 and the water outlet pipe 12 are integrally formed on the volute 13.

[0040] This design further reduces assembly steps and leakage points, ensuring the pump's sealing performance and operational safety.

[0041] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
