Description

Technical Field

[0001] This utility model relates to the technical field of water surface cleaning machines, and in particular to the housing of a water surface cleaning machine and the water surface cleaning machine itself, which prevents the water surface from stagnating on steps. Background Technology

[0002] Debris easily floats on water surfaces, such as in swimming pools, rivers, lakes, and reservoirs. In existing technologies, when using a water surface cleaning machine to collect this debris, the machine is first placed in the water. Because the flotation device generates buoyancy, the filter screen and filter cylinder of the filtration system float on the water. The pumping device is then activated, drawing water into the filter screen. The water then passes through the mesh of the filter screen and flows out of the filter cylinder, creating a continuous cycle. As the water flows into the filter screen, it carries debris from the surface into the screen, where it accumulates.

[0003] When the water surface cleaning machine touches the step, its control system stops the running water pump and reverses the rotation of another water pump, causing water to spray out from the opposite outlet. The reaction force of the water sprayed from the opposite outlet propels the water surface cleaning machine forward, thus changing its direction.

[0004] However, real-world water surface cleaning machines have a drawback: they can only be used at a certain speed. This is because when moving at a relatively high speed, the force exerted by the machine when it contacts the step is greater, resulting in a greater reaction force. Under this reaction force, the machine can move away from the step's contact surface, preventing the water outlet from being blocked. The reaction force of the water jet from the opposite outlet then propels the machine forward, allowing it to change direction and continue moving.

[0005] However, sometimes a slower speed is needed to thoroughly clean the surface debris. But when moving at a slower speed and encountering a step, the machine cannot change direction. This is because the force exerted by the machine on the step is less, resulting in a weaker reaction force. The machine cannot move away from the step and stops at the step surface. At this point, the water outlet in the opposite direction is blocked by the step, preventing water from flowing out and thus hindering the machine's ability to change direction. This reduces the machine's flexibility and cleaning efficiency. Utility Model Content

[0006] To address the aforementioned issue where, when the water surface cleaning machine travels at a slower speed, the force exerted by the machine on the contact surface of the step is less, preventing the machine from moving away under the reaction force of the step's contact surface. Consequently, the water outlet in the opposite direction is blocked by the step's contact surface and cannot be opened, thus preventing the machine from changing direction and reducing its cleaning efficiency, this utility model provides a housing and a water surface cleaning machine designed to prevent it from stopping at steps.

[0007] This utility model provides a housing and a water surface cleaning machine for preventing stagnation at steps, and adopts the following technical solution:

[0008] The housing of a water surface cleaning machine that prevents stagnation at steps includes a housing, a water outlet, and a protrusion. The housing has a water outlet, the water outlet is installed at the water outlet, and the protrusion is located on the outer side wall of the housing and outside the water outlet.

[0009] When the water surface cleaning machine reaches the step, the protrusion abuts against the contact surface of the step. When the water flows out from the inside of the shell through the water outlet near the contact surface, the water outlet near the contact surface is opened by the water flow, and the water flows out from the water outlet near the contact surface.

[0010] By adopting the above technical solution, when the outer shell reaches the step, the protrusion abuts against the contact surface, and the water jet opens the water outlet. The reaction force of the sprayed water jet propels the water surface cleaning machine to move, thus allowing the water surface cleaning machine to change direction and continue moving. The water surface cleaning machine moves forward under the action of the water jet's counter-propulsion.

[0011] Optionally, the number of protrusions at the water outlet is two or more, and the protrusions are symmetrically arranged on both sides of the water outlet.

[0012] By adopting the above technical solution, the other side is prevented from being blocked by the contact surface, ensuring that the water outlet is opened by the water flow.

[0013] Optionally, the outer casing is provided with a door frame, and when the water outlet door is closed, the outer periphery of the water outlet door and the inner periphery of the door frame are fitted with a clearance.

[0014] By adopting the above technical solution, the door frame blocks the rotation of the water outlet door, preventing the water outlet door from tilting on the outer shell, thus ensuring the water outlet door's coverage of the water outlet and further ensuring the accuracy of the water surface cleaning machine's forward and backward directions.

[0015] Optionally, there are two water outlets and two water outlets. The two water outlets are installed on the front and rear sides of the outer casing, respectively, and the two water outlets are opened on the front and rear sides of the outer casing, respectively.

[0016] By adopting the above technical solution, it is possible for the water surface cleaning machine to move in opposite directions.

[0017] A water surface cleaning machine, characterized in that it includes the outer casing of the water surface cleaning machine mentioned above, which prevents the water surface cleaning machine from stagnating at steps.

[0018] Optionally, it includes two pumps, one of which rotates when the water surface cleaner moves forward and the other pump rotates when the water surface cleaner reverses direction.

[0019] By adopting the above technical solution, when the water surface cleaning machine moves forward, one of the water pumps rotates, and water is sprayed out from the rear water outlet. The reaction force of the sprayed water propels the water surface cleaning machine forward. When the water surface cleaning machine touches the step and reverses, the other water pump rotates, and water is sprayed out from the front water outlet, that is, from the water outlet near the step. The reaction force of the sprayed water propels the water surface cleaning machine backward.

[0020] Optionally, it also includes a floating device, a water-drawing shell, a sealed chamber, and a filtering device. The filtering device includes a filter cylinder with a filter screen installed inside. The filter cylinder is installed on top of the water-drawing shell, and an opening is provided at the bottom of the filter cylinder. The water pump, the water-drawing shell, and the sealed chamber are all located inside the outer shell. The water-drawing shell and the filter cylinder form a drainage chamber. The water-drawing shell is installed on top of the sealed chamber, and water outlet cylinders are connected to both the front and rear sides of the water-drawing shell.

[0021] The front water outlet faces the front water outlet cylinder, and the rear water outlet faces the rear water outlet cylinder. The water flowing out of the two water outlet cylinders flows in opposite directions, the water flowing out of the two water outlets flows in opposite directions, and the water sprayed from the two water outlet gates flows in opposite directions.

[0022] The pump includes two sets of motors, the body of which is installed inside the sealed chamber. The top of each set of motors is connected to a rotating shaft, and an impeller is installed at one end of each rotating shaft that extends into the pump casing.

[0023] By adopting the above technical solution, before the water surface cleaning machine touches the contact surface of the step, as the water surface cleaning machine moves forward, the rear pump rotates, and water flows out sequentially from the filter screen, filter cylinder, opening, rear pump, rear outlet cylinder, rear outlet, and rear water gate. The reaction force of the water flow sprayed from the rear water gate propels the water surface cleaning machine forward. When the water surface cleaning machine touches the contact surface of the step, the front pump rotates. Because there is a protrusion against the contact surface, the water gate is not blocked by the contact surface, and the water flow can spray out from the water gate. Therefore, water flows out sequentially from the filter screen, filter cylinder, opening, front pump, front outlet cylinder, front outlet, and front water gate. The reaction force of the water flow sprayed from the front water gate propels the water surface cleaning machine backward.

[0024] In summary, this utility model has at least one of the following beneficial effects:

[0025] This invention utilizes a protruding block. When the outer shell reaches the step, the protruding block abuts against the contact surface. At this time, the water jet opens the water outlet, and the reaction force of the jet propels the water surface cleaner forward. This allows the water surface cleaner to change direction and continue moving, thus advancing under the action of the water jet's counter-propulsion.

[0026] This utility model, through the design of the door frame, obstructs the rotation of the water outlet door, preventing the water outlet door from tilting on the outer casing, thereby ensuring the water outlet door covers the water outlet and further guaranteeing the accuracy of the water surface cleaning machine's forward and backward directions.

[0035] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail below.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 5 and Figure 6 The present invention provides an embodiment of a water surface cleaning machine housing that prevents stagnation at steps, comprising a housing 1, a water outlet 2, and a protrusion 3. The housing 1 has a water outlet 6, the water outlet 2 is installed at the water outlet 6, and the protrusion 3 is located on the outer side wall of the housing 1, and is located outside the water outlet 2. When the water surface cleaning machine reaches the step 15, the protrusion 3 abuts against the contact surface 16 of the step 15. When water flows out from inside the housing 1 through the water outlet 6 near the contact surface 16, the water outlet 2 near the contact surface 16 is opened by the water flow, and the water flows out from the water outlet 2 near the contact surface 16.

[0037] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 3 , Figure 4 and Figure 5 There are two or more protrusions 3 at the outlet 6, and the protrusions 3 are symmetrically arranged on both sides of the outlet gate 2. This prevents the other side from being blocked by the contact surface 16, ensuring that the outlet gate 2 can be opened by the water flow.

[0038] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 5 and Figure 6 The outer casing 1 is provided with a door frame 14. When the water outlet 2 is closed, the outer periphery of the water outlet 2 is fitted with the inner periphery of the door frame 14 with a clearance. The door frame 14 has a blocking effect on the rotation of the water outlet 2, which can prevent the water outlet 2 from tilting on the outer casing 1, thereby ensuring the coverage of the water outlet 6 by the water outlet 2, and further ensuring the accuracy of the forward and backward directions of the water surface cleaning machine.

[0039] Please refer to the attached diagram in the instruction manual. Figure 2, Figure 3 and Figure 5 There are two water outlets 2 and two water outlets 6. The two water outlets 2 are installed on the front and rear sides of the outer casing 1, respectively, and the two water outlets 6 are also located on the front and rear sides of the outer casing 1. This allows the water surface cleaning machine to move in opposite directions.

[0040] A water surface cleaning machine, including the housing of the aforementioned water surface cleaning machine that prevents stagnation on steps.

[0041] Please refer to the attached diagram in the instruction manual. Figure 4 and Figure 5 It includes two water pumps. When the water surface cleaner moves forward, one pump rotates; when the water surface cleaner reverses direction, the other pump rotates. When the water surface cleaner moves forward, one pump rotates, and water is sprayed out from the rear water outlet 2. The reaction force of the sprayed water propels the water surface cleaner forward. When the water surface cleaner touches the step 15 and reverses direction, the other pump rotates, and water is sprayed out from the front water outlet 2, that is, from the water outlet 2 closest to the step 15. The reaction force of the sprayed water propels the water surface cleaner backward.

[0042] Please refer to the attached diagram in the instruction manual. Figure 3 , Figure 4 and Figure 5 It also includes a floating device 4, a water-drawing shell 11, a sealed chamber 10, and a filtering device. The filtering device includes a filter cylinder 5, with a filter screen 13 installed inside the filter cylinder 5. The filter cylinder 5 is installed on the top of the water-drawing shell 11, and an opening is provided at the bottom of the filter cylinder 5. The water pump, the water-drawing shell 11, and the sealed chamber 10 are all located inside the outer shell 1. The water-drawing shell 11 and the filter cylinder 5 form a drainage chamber 7. The water-drawing shell 11 is installed on the top of the sealed chamber 10, and water outlet cylinders 17 are connected to both the front and rear sides of the water-drawing shell 11.

[0043] Please refer to the attached diagram in the instruction manual. Figure 4 , Figure 5 and Figure 6 The front water outlet 6 is directly opposite the front water outlet 17, and the rear water outlet 6 is directly opposite the rear water outlet 17. The water flowing out of the two water outlets 17 flows in opposite directions, the water flowing out of the two water outlets 6 flows in opposite directions, and the water sprayed out from the two water outlets 2 flows in opposite directions.

[0044] Please refer to the attached diagram in the instruction manual. Figure 2 , Figure 3 and Figure 5The pump includes two sets of motors 9. The body parts of the two sets of motors 9 are installed inside the sealed chamber 10. The top of the two sets of motors 9 are connected to the rotating shafts 8. The end of the two sets of rotating shafts 8 that extends into the pump casing 11 is equipped with an impeller 12. Before the water surface cleaning machine touches the contact surface 16 of step 15, as the water surface cleaning machine moves forward, the rear pump rotates, and water flows out sequentially from the filter screen 13, filter cylinder 5, opening, rear pump, rear outlet cylinder 17, rear outlet 6, and rear outlet gate 2. The reaction force of the water flow sprayed from the rear outlet gate 2 propels the water surface cleaning machine forward. When the water surface cleaning machine touches the contact surface 16 of step 15, the front pump rotates. Because the protrusion 3 abuts against the contact surface 16, the outlet gate 2 is not blocked by the contact surface 16, and the water flow can spray out from the outlet gate 2. Therefore, water flows out sequentially from the filter screen 13, filter cylinder 5, opening, front pump, front outlet cylinder 17, front outlet 6, and front outlet gate 2. The reaction force of the water flow sprayed from the front outlet gate 2 propels the water surface cleaning machine backward.

[0045] Working principle: When in use, place the water surface cleaner on the water surface to be cleaned. With the floating device 4, the cleaner floats on the surface. Then, start the water pump. The floating debris flows into the filter cylinder 5 with the water flow and is intercepted by the filter screen 13. The water enters the drain chamber 7 through the opening at the bottom of the filter cylinder 5. The water pump drains the water that has entered the filter screen 13 through the water outlet cylinder 17. The water flowing out of the water outlet cylinder 17 propels the automatic water surface cleaner to move on the water surface. In this way, water continuously flows from the filter cylinder 5 into the filter screen 13, and the water that enters the filter screen 13 is continuously drained by the water pump.

[0046] Before the water surface cleaning machine touches the contact surface 16 of the step 15, when the water surface cleaning machine moves forward, the rear pump rotates, and water flows out in sequence from the filter screen 13, filter cylinder 5, opening, rear pump, rear outlet cylinder 17, rear outlet 6, and rear outlet gate 2. The reaction force of the water flow sprayed from the rear outlet gate 2 propels the water surface cleaning machine forward.

[0047] When the water surface cleaning machine touches the contact surface 16 of the step 15, the front water pump rotates. Because the protrusion 3 abuts against the contact surface 16, the water outlet 2 is not blocked by the contact surface 16, and the water can spray out from the water outlet 2. Therefore, the water flows out sequentially from the filter screen 13, filter cylinder 5, opening, front water pump, front water outlet cylinder 17, front water outlet 6, and front water outlet 2. The reaction force of the water sprayed from the front water outlet 2 pushes the water surface cleaning machine backward. As the water surface cleaning machine moves backward, the water outlet 2 opens wider and wider, and the water surface cleaning machine continues to move backward.

[0048] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
