Description

Technical Field

[0001] The utility model relates to the technical field of fountain pumps, in particular to a fountain pump which is convenient for adjusting outlet pressure. Background Art

[0002] Fountains are generally arranged in public places such as hotels and squares. At present, the outer shell of the fountain pump device is generally cylindrical, and the fountain pump device is not equipped with a nozzle, a check valve, etc. Professional construction personnel are required to fix the fountain pump device in the fountain pool and install the nozzle, check valve and nozzle on the fountain pump device. The installation is relatively troublesome. With the improvement of people's living standards, many families have small pools in their small courtyards, and many people want to install fountains in the pools.

[0003] However, the fountain pump devices currently on the market need to be assembled and fixed and cannot be used directly; furthermore, the nozzles currently installed on the fountain pump devices are all hollow tubes, and no flow stabilizing structure is arranged in the nozzles, which affects the stability of the water flow sprayed by the fountain and the effect of the water shape.

[0004] For example, a fountain pump device disclosed in Chinese patent CN219850386U has a rectangular shell outside the pump body and the motor, a nozzle with a right-angle elbow is fixed to one end of the shell, a check valve is connected above the nozzle, and a nozzle is connected above the check valve. No assembly is required, and the fountain pump device can be used by simply placing it flat on the bottom of the pool. It is easy to use. A cross-shaped flow stabilizer is provided in the vertical end of the nozzle to make the water flow sprayed by the fountain more stable and the water spraying effect better.

[0005] However, the outlet of the fountain pump device cannot generate pressure, thereby making it impossible to adjust the height of the fountain being ejected.

[0006] For this reason, we urgently need to provide a fountain pump that is easy to adjust the outlet pressure. Utility Model Content

[0007] The utility model aims to provide a fountain pump which is easy to adjust the outlet pressure, so as to solve the problem that the outlet of the fountain pump device proposed in the above background technology cannot be pressurized, and thus the height of the ejected fountain cannot be adjusted.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fountain pump which is convenient for adjusting the outlet pressure, comprising a fixed box and a pump body, wherein the pump body is fixedly connected to the inside of the fixed box, a water outlet pipe is fixedly connected to the left end of the pump body, a nozzle is fixedly connected to the end of the water outlet pipe away from the pump body, an adjusting mechanism is connected to the inner and outer ends of the fixed box and the water outlet pipe, the adjusting mechanism comprises an adjusting unit and a cleaning unit, the adjusting unit is arranged at the inner and outer ends of the water outlet pipe, and the cleaning unit is arranged at the upper rear end of the fixed box.

[0009] The adjusting unit includes a rectangular plate, a telescopic member, a gear rod, a circular plate, a rotating rod and a gear, wherein the rectangular plate is fixedly connected to the outer upper end of the water outlet pipe, the telescopic member is fixedly connected to the front right end of the rectangular plate, the gear rod is fixedly connected to the left end of the output shaft of the telescopic member, the circular plate is connected to the inner upper end of the water outlet pipe, the rotating rod is fixedly connected to the outer front end of the circular plate, and the gear is fixedly connected to the outer side of the front end of the rotating rod.

[0010] A further improvement is that a rotation hole is provided at the middle position of the front end of the rectangular plate and the middle position of the front end of the rectangular plate inside the water outlet pipe, the outer side of the rotation rod is rotationally connected to the inner side of the rotation hole, and the outer side of the circular plate is slidingly connected to the inner side of the water outlet pipe. Therefore, when the rotation rod rotates in the rotation hole, the circular plate located inside the water outlet pipe can be driven to rotate.

[0011] A further improvement is that the lower end of the gear rod is meshed with the outer end of the gear, so that when the output shaft of the telescopic member is started to move and the gear rod is driven to move, the gear can be driven to rotate, thereby driving the rotating rod to rotate, so that the circular plate can be rotated, thereby changing the flow rate at the circular plate inside the water outlet pipe, and at the same time changing the pressure of the water outlet, so that the fountain can be sprayed to different heights.

[0012] A further improvement is that the cleaning unit includes a rectangular frame, a motor, a reciprocating screw, a bearing, a sliding block and a scraper, the rectangular frame is fixedly connected to the upper end of the rear side of the fixed box, the motor is fixedly connected to the middle position of the right side of the rectangular frame, the reciprocating screw is fixedly connected to the left end of the output shaft of the motor, the bearing is fixedly connected to the middle position of the inner left end of the rectangular frame, the sliding block is connected to the outer end of the reciprocating screw, and the scraper is fixedly connected to the front side of the sliding block.

[0013] A further improvement is that a threaded hole is provided in the middle of the sliding block, the outer side of the left end of the reciprocating screw is fixedly connected to the inner side of the bearing, the outer side of the reciprocating screw is threadedly connected to the inner side of the threaded hole, and the upper and lower sides of the sliding block are slidably connected to the inner side of the rectangular frame. Thus, when the output shaft of the motor is started and the reciprocating screw is driven to rotate, the sliding block on the outer side can be driven to slide along the inner side of the rectangular frame, thereby driving the scraper to move together.

[0014] A further improvement is that water inlet holes are opened at equal distances on the upper end of the fixed box, and the lower side of the scraper is slidably connected to the upper side of the fixed box. Thus, by adjusting the position of the sliding block, when the scraper is located on the upper side of the fixed box and slides, impurities on the upper side of the fixed box can be scraped off to prevent the water inlet holes on the upper end of the fixed box from being blocked.

[0015] A further improvement is that a rubber pad is fixedly connected to the outer side of the rotating rod, so that when the rotating rod rotates in the rotating hole, the rubber pad on the outer side of the rotating rod contacts the inner side of the rotating hole, thereby preventing water entering the water outlet pipe from leaking out of the rotating hole and affecting the pressure of the water outlet.

[0016] In summary, the present application discloses a fountain pump that is convenient for adjusting the outlet pressure.

[0017] This technical solution starts the telescopic part and moves its output shaft to drive the gear rod to move, which can drive the gear to rotate, thereby driving the rotating rod to rotate, causing the circular plate to rotate, thereby changing the flow rate at the circular plate inside the water outlet pipe, and at the same time changing the pressure of the water outlet, so that the fountain is sprayed to different heights.

[0018] Furthermore, by starting the motor and rotating its output shaft to drive the reciprocating screw to rotate, the outer sliding block can be driven to slide along the inner side of the rectangular frame. At the same time, the scraper can be driven to slide along the upper side of the fixed box to scrape off the impurities on the upper side of the fixed box to prevent the water inlet hole at the upper end of the fixed box from being blocked.
