[0022] See also Figure 1 , Figure 1 It is a structural schematic diagram of a cross-sectional view of a water pump provided in this application.

[0023] The present application provides a water pump. Figure 1 As shown, the water pump of this embodiment includes: a pump body 10, a jet part 20 and a guide part 40. The water pump can be, but is not limited to, a centrifugal pump, and can also be other water pumps, such as an axial flow pump, a positive displacement pump, etc., which are not specifically limited in this application. A accommodating space 101 is formed in the pump body 10, and the accommodating space 101 is used to accommodate gas or a gas-liquid mixture. An impeller 102 is arranged in the accommodating space 101, and the impeller 102 is started to discharge the gas or gas-liquid mixture in the accommodating space 101, wherein the impeller 102 can be a single-suction impeller 102, and when a large flow of liquid needs to be pumped, a double-suction impeller 102 can also be used. The jet part 20 is arranged at one end of the pump body 10, and the jet part 20 is connected to the accommodating space 101 of the pump body 10, and a water inlet 301 is arranged at one end of the jet part 20 away from the pump body 10. The jet part 20 can be specifically a hollow jet part 20. When the impeller 102 is started so that the pump body 10 starts to pump water, the water inlet 301 passes the liquid into the jet part 20, and the liquid is pumped into the accommodating space 101 through the jet part 20 and the rotating impeller 102, and then discharged to the water outlet pipe. The guide part 40 is arranged at the end of the jet part 20 away from the pump body 10, and is connected with the accommodating space 101 of the pump body 10, that is, one end of the guide part 40 is connected with the end of the jet part 20 away from the pump body 10, and the other end is connected with the accommodating space 101 of the pump body 10. A nozzle 401 is arranged at the end of the guide part 40 connected to the jet part 20, and the nozzle 401 is at least partially located in the jet part 20 and corresponds to the water inlet 301. That is, a water inlet 301 is correspondingly provided at the connection between the guide portion 40 and the jet portion 20 , and the nozzle 401 is arranged inside the jet portion 20 and corresponding to the water inlet 301 .

[0024] In some embodiments, when the water pump is started to pump liquid, the impeller 102 in the pump body 10 is started first. The impeller 102 rotates to discharge the gas or gas-liquid mixture in the accommodating space 101 of the pump body 10. At this time, the gas or gas-liquid mixture in the accommodating space 101 enters the guide portion 40. The gas or gas-liquid mixture in the guide portion 40 can be sprayed out through the nozzle 401 set on the jet portion 20, thereby entering the jet portion 20. Since the flow rate of the liquid sprayed in the nozzle 401 is high, a negative pressure state is formed in the jet portion 20. At this time, the liquid in the water inlet portion 301 can quickly enter the jet portion 20 under the action of atmospheric pressure, and be transmitted to the accommodating space 101 of the pump body 10 through the jet portion 20. That is, the water inlet 301 of the jet part 20 is located in the liquid to be pumped, and the impeller 102 rotates so that the gas in the accommodating space 101 is discharged into the jet part 20 through the nozzle 401 of the guide part 40. Since the gas flow rate ejected from the nozzle 401 is high, a negative pressure state is formed in the jet part 20, so that under the combined action of the rotation of the impeller 102 and the negative pressure, the liquid quickly passes through the jet part 20 into the accommodating space 101 and is discharged through the pump body 10. In this embodiment, when the water pump is started for the first time, there is no liquid in the accommodating space 101 of the pump body 10, that is, when the impeller 102 is started to rotate, the airflow or gas-liquid mixture in the accommodating space 101 can be sprayed into the inside of the jet part 20 through the nozzle 401 on the guide part 40, so that the water pump quickly completes self-priming, thereby forming a negative pressure state in the jet part 20 to increase the speed of the water pump when pumping liquid.

[0025] In a specific application scenario, the water pump is used in a smart toilet as an example. After the user uses the smart toilet, the smart toilet needs to be flushed. At this time, the water pump is started to make the impeller 102 in the pump body 10 start to rotate, so that the airflow or gas-liquid mixture in the accommodating space 101 is sprayed into the jet part 20 through the nozzle 401 on the guide part 40, thereby forming a negative pressure in the jet part 20. Under the action of the impeller 102 and the negative pressure, the speed at which the water inlet part 301 extracts the liquid in the smart toilet is accelerated, effectively improving the pumping speed of the water pump, thereby improving the pumping speed of the smart toilet.

[0026] In the above embodiment, a jet portion 20 connected to the accommodating space 101 is provided at one end of the pump body 10, and the end of the jet portion 20 away from the pump body 10 is connected to the guide portion 40, and the other end of the guide portion 40 is connected to the accommodating space 101 of the pump body 10. When the water pump is pumping water, the impeller 102 arranged in the accommodating space 101 is controlled to rotate, so that the gas or gas-liquid mixture in the accommodating space 101 is sprayed into the jet portion 20 through the nozzle 401 on the guide portion 40, thereby forming a negative pressure in the jet portion 20, so that the liquid quickly enters the jet portion 20 through the water inlet portion 301 under the action of the negative pressure, and the liquid in the jet portion 20 is transmitted to the accommodating space 101 of the pump body 10 under the action of the impeller 102, thereby quickly completing the self-priming water pumping.

[0027] In some embodiments, a shell cover 103 is provided at one end of the pump body 10 away from the jet portion 20 to form a accommodating space 101, and a drive component 106 is provided in the accommodating space 101. Specifically, the drive component 106 is provided inside the shell cover 103, and the drive component 106 is provided in the accommodating space 101 away from the jet portion 20. When the water pump needs to pump water, the drive component 106 can be started by controlling the drive component 106, and the drive component 106 drives the impeller 102 to start rotating. The rotation of the impeller 102 causes the gas and the gas-liquid mixture in the accommodating space 101 to be transmitted to the jet portion 20 through the guide portion 40. The pump body 10 is provided with a water outlet 302, that is, when the impeller 102 rotates, part of the gas and the gas-liquid mixture is transmitted through the water outlet 302, and the other part is transmitted through the guide part 40, and is sprayed into the jet part 20 through the nozzle 401 on the guide part 40, thereby forming a negative pressure in the jet part 20, so that the liquid quickly enters the jet part 20 through the water inlet 301, and enters the accommodating space 101 under the action of the impeller 102, and is transmitted through the water outlet 302, completing the self-priming pumping liquid. In this embodiment, the water outlet 302 and the water inlet 301 are located on opposite sides of the water pump.

[0028] In some embodiments, a suction chamber 201 is provided at one end of the jet portion 20 away from the pump body 10, that is, the nozzle 401 is at least partially located inside the suction chamber 201, and the water inlet portion 301 corresponds to the suction chamber 201 and is connected to the suction chamber 201. That is, in the accommodating space 101, the gas or gas-liquid mixture is sprayed into the suction chamber 201 through the nozzle 401 on the guide portion 40 through the impeller 102, so that negative pressure is formed during suction, so that the liquid automatically enters the suction chamber 201 through the water inlet portion 301. In the present embodiment, the suction chamber 201 is provided at one end of the suction chamber 201 close to the pump body 10, that is, after the liquid enters the suction chamber 201 through the water inlet 301 under the negative pressure state, the liquid enters the mixing section 202 from the suction chamber 201 under the action of the impeller 102. In order to accelerate the liquid sucked into the suction chamber 201, the opening of the mixing section 202 away from the suction chamber 201 is gradually reduced. Due to the high flow rate of the gas jet in the nozzle 401, a negative pressure is formed in the suction chamber 201. At this time, the airflow and liquid in the suction chamber 201 are mixed in the suction chamber 201 and the mixing section 202, thereby forming a high-speed mixed flow in the mixing section 202, thereby accelerating the speed at which the liquid enters the suction chamber 201 through the water inlet 301, completing the self-priming process of the water pump.

[0029] In some embodiments, a water inlet section 104 connected to the accommodating space 101 is provided at one end of the pump body 10 close to the jet portion 20, and a compression section 204 connected to the water inlet section 104 is provided at one end of the jet portion 20 close to the pump body 10, and a connecting section 203 is connected between the compression section 204 and the mixing section 202. The connecting section 203 is coaxially arranged with the mixing section 202 and the compression section 204, that is, when the gas or gas-liquid mixture is quickly sprayed into the suction chamber 201 through the nozzle 401, a negative pressure is formed in the suction chamber 201, so that the liquid enters the suction chamber 201 through the water inlet 301. After the liquid enters the suction chamber 201, the gas and the liquid begin to mix in the mixing section 202, and because the opening of the mixing section 202 away from the suction chamber 201 gradually decreases, the high-speed mixed flow in the mixing section 202 is accelerated in the mixing section 202, and the connecting section 203 is connected to the end of the mixing section 202 close to the pump body 10, that is, the opening of the connecting section 203 is equivalent to the smaller opening of the mixing section 202. , so that the mixed flow in the mixing section 202 enters the connecting section 203 at a faster speed and is mixed completely. When the fast mixed flow passes through the connecting section 203 and enters the compression section 204, since the opening of the compression section 204 close to the water inlet section 104 gradually increases, the high-speed mixed flow in the connecting section 203 enters the compression section 204 with a gradually increasing opening, so that part of the kinetic energy of the high-speed mixed flow is converted into static pressure energy in the compression section 204, which is conducive to the mixed flow entering the accommodating space 101 through the water inlet section 104 under the action of the static pressure energy, and then entering the inlet of the impeller 102. Under the action of the impeller 102, the liquid is discharged through the water outlet 302, thereby completing the rapid start-up of the water pump.

[0030] In a specific application scenario, when it is necessary to start the water pump, the driving component 106 can be controlled to start the impeller 102 to rotate, so that the gas and the gas-liquid mixture in the accommodating space 101 of the pump body 10 are partially discharged through the water outlet 302, and the other part enters the guide part 40 and is sprayed into the suction chamber 201 of the jet part 20 through the nozzle 401, so that a negative pressure is formed in the suction chamber 201, so that the water inlet 301 draws the liquid into the suction chamber 201, and mixes in the suction chamber 201 and the mixing section 202 to form a mixed flow. Since the mixing section 202 gradually decreases away from the opening of the suction chamber 201, the flow rate of the mixed flow increases in the mixing section 202. The mixed flow enters the connecting section 203 through the mixing section 202, is accelerated in the mixing section 202, and enters the compression section 204. Since the opening of the compression section 204 close to the pump body 10 gradually increases, part of the kinetic energy of the mixed flow is converted into static pressure energy in the compression section 204. Under the action of the static pressure energy, the mixed flow enters the accommodating space 101 through the water inlet section 104 of the main body, and enters the inlet of the impeller 102. Under the action of the rotation of the impeller 102, the liquid is discharged through the water outlet 302, thereby quickly completing the start-up of the water pump. Among them, since the diameter of the guide part 40 is smaller than the diameter of the water outlet part 302, after the water pump is started, when the liquid in the subsequent accommodating space 101 enters the guide part 40, the internal water flow of the guide part 40 enters the suction chamber 201 through the nozzle 401. Since the flow rate in the guide part 40 is small, the pumping efficiency of the water pump will not be reduced.

[0031] In some embodiments, a fastener 50 is provided at one end of the flow guide 40 close to the nozzle 401, and the fastener 50 is connected to the outer wall of the jet part 20 away from the pump body 10, so as to facilitate the flow guide 40 and the nozzle 401 to be fixed to the end of the jet part 20 away from the pump body 10. Specifically, the fastener 50 can be fixed to the jet part 20 by screws, or by bonding, which is not specifically limited in this application. That is, the flow guide 40 and the nozzle 401 are detachably connected to the jet part 20 through the fastener 50, so as to facilitate the replacement of the flow guide 40 and the nozzle 401. In order to improve the sealing between the jet part 20 and the guide part 40 and reduce the water seepage at the connection between the jet part 20 and the guide part 40, a sealing ring 501 is provided between the fastener 50 and the outer wall of the jet part 20, and the fastener 50 is clamped and fixed with the outer wall of the jet part 20, thereby improving the sealing between the jet part 20 and the guide part 40. Specifically, a groove can be provided at the end of the fastener 50 close to the jet part 20, and the sealing ring 501 can be arranged in the groove, and then the nozzle 401 of the guide part 40 is inserted into the jet part 20, and the fastener 50 is clamped with the outer wall of the jet part 20, so that the sealing ring 501 is deformed, thereby effectively improving the sealing between the guide part 40 and the jet part 20. In other embodiments, a sealing ring 501 can be provided between the fastener 50 and the guide part 40, so that the water seepage between the guide part 40 and the jet part 20 can be effectively reduced through multi-layer sealing.

[0032] In some embodiments, a flow guide port 105 is provided on the side wall of the pump body 10 corresponding to the impeller 102, and the flow guide port 105 is connected to the flow guide portion 40, and the flow guide port 105 is connected to the accommodating space 101. When the impeller 102 rotates, the airflow or gas-liquid mixture in the accommodating space 101 is transmitted to the flow guide portion 40 through the flow guide port 105. In this embodiment, a joint pipe 402 is provided on the flow guide port 105, that is, one end of the joint pipe 402 is connected to the flow guide port 105, and the other end is connected to the flow guide portion 40. Among them, the joint pipe 402 can be threadedly connected to the flow guide port 105, so as to facilitate the replacement of the flow guide portion 40. In other embodiments, the flow guide portion 40 can also be connected to the flow guide portion 40 on the flow guide port 105 by other methods, for example, the flow guide portion 40 is inserted into the flow guide port 105 and fixed by bonding, which is not specifically limited in this application.

[0033] In some embodiments, the guide part 40 may adopt a flexible conduit, so that when the water pump is installed in the product, it is convenient to layout the product and improve the layout capability of the product. The jet part 20 may adopt an integrally formed structure, and the jet part 20 and the pump body 10 are detachably connected, that is, the compression section 204 of the jet part 20 is connected to the water inlet section 104 of the pump body 10. When the jet part 20 is installed at one end of the pump body 10, a seal may be provided between the jet part 20 and the pump body 10, and the side wall of the compression section 204 of the jet part 20 and the side wall of the water inlet section 104 of the pump body 10 are clamped and fixed. The jet part 20 and the pump body 10 are clamped and fixed, so that the seal is deformed, thereby improving the sealing of the water pump. Among them, the jet part 20 and the guide part 40 may be connected by screws or by pins, and this application does not make specific limitations here.

[0034] In a specific application scenario, when the water pump is started, the control driving assembly 106 drives the impeller 102 to rotate, so that the airflow and the gas-liquid mixture in the accommodating space 101 partially enter the guide part 40 through the guide port 105, and are sprayed into the suction chamber 201 of the jet part 20 through the nozzle 401 arranged at the end of the guide part 40 away from the pump body 10, so that the suction chamber 201 forms a negative pressure, and the liquid enters the suction chamber 201 through the water inlet 301, and is mixed in the suction chamber 201 of the jet part 20 and the mixing section 202 to form a high-speed mixed flow, and enters the connecting section 2 03, is accelerated in the connecting section 203, and is passed into the compression section 204, in which part of the kinetic energy of the high-speed mixed flow is converted into static pressure energy, and under the action of the static pressure energy, the mixed flow passes through the water inlet section 104 of the pump body 10 into the accommodating space 101, and is then discharged through the water outlet 302, thereby completing the start-up of the water pump, and after the start-up of the water pump is completed, the liquid that enters the jet section 20 through the water inlet section 301 also passes through the mixing section 202, the connecting section 203 and the compression section 204, so that the water flow enters the water pump more efficiently, thereby improving the water pumping capacity of the water pump.

[0035] In the above manner, the present application sets a jet part 20 connected to the accommodating space 101 at one end of the pump body 10, connects the guide part 40 at one end of the jet part 20 away from the pump body 10, and sets a nozzle 401 at one end of the guide part 40 away from the pump body 10. When the water pump is pumping water, the impeller 102 rotates so that the gas or gas-liquid mixture in the accommodating space 101 is sprayed into the jet part 20 through the nozzle 401 on the guide part 40, thereby forming a negative pressure in the jet part 20, so that the liquid quickly passes through the water inlet part 301 and enters the jet part 20 under the action of the negative pressure, so that the water pump starts quickly. By setting a shell cover 103 at one end of the pump body 10 away from the jet part 20, and setting a drive component in the accommodating space 101, the drive component 106 can be controlled to drive the impeller 102 to rotate, completing the self-priming start and pumping of the water pump. By setting a suction chamber 201 at the end of the jet part 20 away from the pump body 10, and setting a water inlet 301 corresponding to the suction chamber 201, when the nozzle 401 sprays gas or gas-liquid mixture, a negative pressure can be formed in the suction chamber 201, so that the liquid can quickly enter the suction chamber 201. By setting a mixing section 202 at the end of the jet part 20 close to the suction chamber 201, and the opening of the mixing section 202 away from the suction chamber 201 is gradually reduced, the airflow sprayed from the nozzle 401 and the liquid entering from the water inlet 301 can be mixed into a high-speed mixed flow in the mixing section 202, thereby increasing the water intake speed of the water pump. By setting a connecting section 203 at the end of the mixing section 202 away from the suction chamber 201, the high-speed mixed flow can be accelerated again. By providing a compression section 204 at the end of the connecting section 203 away from the pump body 10, and gradually increasing the opening at the end close to the pump body 10, part of the kinetic energy of the mixed flow can be converted into static pressure energy, so that the mixed flow can quickly enter the water inlet section 104. By providing a fastener 50 at the end of the guide part 40 close to the nozzle 401, and providing a sealing ring 501 between the fastener 50 and the outer wall of the jet part 20, the sealing between the jet part 20 and the guide part 40 can be effectively improved.
