[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 One embodiment provided by this utility model:
[0023] A water pump with a flow guide groove includes a driver 1. The output end of the driver 1 is provided with a pump housing 11. An inlet 12 and an outlet 13 are provided on the surface of the pump housing 11. Liquid entering through the inlet 12 is discharged through the outlet 13. An inlet pipe is connected to the inlet 12, and an outlet pipe is connected to the outlet 13, both connected by flanges. A flow guide mechanism is provided on the surface of the outlet 13, including a flow guide groove body 2. The flow guide groove body 2 is fixedly connected to the surface of the driver 1. An external threaded ring 21 is fixedly connected to the surface of the pump housing 11. An internal threaded baffle 22 is threadedly connected to the surface of the external threaded ring 21. A return pipe 23 is fixedly connected to the bottom of the pump housing 2. An inlet 12 is fixedly connected to the end of the return pipe 23 away from the pump housing 2. A drain pipe 24 is fixedly connected to the bottom of the pump housing 2. A nut 25 is threadedly connected to the surface of the drain pipe 24. This pumping mechanism can guide the water leaking from the outlet 13 and the outlet pipe back to the pump housing 11 for discharge again, thus preventing the leaked water from affecting the entire pump.
[0024] Furthermore, an alarm mechanism is provided on the surface of the outlet 13. The alarm mechanism includes a mounting plate 3, which is fixedly connected to the surface of the outlet 13. A bolt head 31 is inserted into the surface of the mounting plate 3, and an alarm 32 is fixedly connected to the surface of the bolt head 31. A locking nut 33 is threaded onto the surface of the bolt head 31. An output signal line 34 is fixedly connected to the input end of the alarm 32, and the output signal line 34 passes through the bolt head 31. A contact sensor 35 is fixedly installed on the inner side of the guide channel body 2, and the end of the output signal line 34 away from the alarm 32 passes through the guide channel body 2 and is fixedly connected to the output end of the contact sensor 35. The contact sensor 35 is a capacitive liquid level sensor, which can sense the water level through electrodes, thereby determining whether there is leakage at the connection of the outlet 13.
[0025] Furthermore, the guide channel body 2 is funnel-shaped, and a water storage tank is formed on the surface of the outlet 13. The guide channel body 2 guides the water in the water storage tank back to the inlet 12 through the return pipe 23. The water inside the inlet 12 will return to the pump casing 11 for centrifugal output.
[0026] Furthermore, the internally threaded baffle 22 is installed on the top of the guide channel body 2 via the externally threaded ring 21. The height of the internally threaded baffle 22 is at the top of the outlet 13. A circular hole is opened on the surface of the internally threaded baffle 22, and the diameter of the circular hole of the internally threaded baffle 22 is larger than the diameter of the outlet 13, so that the flange on the outlet 13 can pass through. This makes it convenient to install the internally threaded baffle 22 on the guide channel body 2 after the outlet 13 and the outlet pipe are connected. The internally threaded baffle 22 can block the water sprayed from the outlet 13, so that the water source flows down to the water storage tank of the guide channel body 2. In addition, the internally threaded baffle 22 can provide physical protection for the connection between the outlet 13 and the outlet pipe.
[0027] Furthermore, the drain pipe 24 is inclined at an angle, and one end of the drain pipe 24 is provided with an external thread. The horizontal height of the drain pipe 24 is lower than the height of the top of the return pipe 23. The drain pipe 24 can drain all the water on the outlet of the guide channel body 2. The nut 25 seals the drain pipe 24.
[0028] Furthermore, the mounting plate 3 is triangular in shape, and one side of the mounting plate 3 is fixedly connected to the surface of the pump housing 11, ensuring the structural stability of the mounting plate 3. A circular hole is opened on the surface of the mounting plate 3, and the bolt head 31 is inserted into the circular hole of the mounting plate 3, thereby determining the installation position of the alarm 32 on the mounting plate 3.
[0029] Furthermore, the bolt head 31 mounts the alarm 32 onto the surface of the mounting plate 3 via the locking nut 33. The locking nut 33 is octagonal and requires a wrench to operate. The contact sensor 35 drives the alarm 32 to sound an alarm on the mounting plate 3 via the output signal line 34. When there is water in the water storage tank of the guide channel body 2, the nut 25 outputs a signal to the contact sensor 35 via the output signal line 34, thereby causing the contact sensor 35 to sound an alarm.
[0030] Working principle: The internal threaded baffle 22 is threaded onto the surface of the external threaded ring 21, completing the installation of the internal threaded baffle 22 on the guide channel body 2. When leakage occurs at the connection between the outlet 13 and the outlet pipe, water will spray onto the surface of the internal threaded baffle 22. The water will flow along the internal threaded baffle 22 to the water storage tank formed on the surface of the outlet 13 of the guide channel body 2. The guide channel body 2 guides the water in the water storage tank to the inlet 12 through the return pipe 23. The water is then guided back into the pump housing 11 through the inlet 12, preventing the water leaking at the outlet 13 from spraying onto the pump, thus ensuring the safe use of the pump and extending its service life.
[0031] Insert the bolt head 31 into the circular hole of the mounting plate 3, and then tighten the locking nut 33 on the bolt head 31 by turning the wrench. The bolt head 31 and the locking nut 33 will install the alarm 32 on the mounting plate 3. Drain the water in the water storage tank of the guide channel body 2 through the drain pipe 24. Then thread the nut 25 onto the drain pipe 24. When there is water in the water storage tank of the guide channel body 2, it proves that there is a leak at the outlet 13. The contact sensor 35 directly contacts the water source and sends a leak signal to the alarm 32 through the output signal line 34, so that the alarm 32 will sound an alarm on the mounting plate 3, thereby improving the safety of the water pump during use.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
