Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of exhaust devices, in particular to a cleaner water pipe exhaust device. BACKGROUND

[0002] The pool cleaner is one of the core equipment of the pool circulating filtration system, and mainly functions to make the water in the pool flow continuously, and through the pipeline, the water is pumped out of the pool, transported to the filtering equipment for purification treatment, and then the clean water after treatment is sent back to the pool.

[0003] In the related art, the pool cleaner is composed of a water pump impeller, a water pump volute, a motor and a pump shaft, the pump shaft is used to connect the center of the impeller and the motor, a front cover plate of the water pump impeller is provided with a circular hole-shaped impeller water inlet at the center position, and a hose is installed at the water inlet. When the pool cleaner works, the hose needs to be put into the water, the water inlet pipeline valve of the water pump is opened, and after the pump shell is filled with water, the motor drives the water pump impeller to rotate, the water is thrown out of the impeller under the action of centrifugal force, and is pressed to the water outlet through the volute. At this time, a vacuum is formed at the center of the water pump impeller due to the throwing of water, and the water in the pool is continuously sucked into the center of the impeller under the action of atmospheric pressure along the water suction pipeline (return water pipeline) of the water pump, and is thrown out of the impeller under the action of the high-speed rotating impeller to input into the pressure pipeline connected with the outlet of the water pump, thereby forming continuous water delivery of the water pump.

[0004] In the related art, when the hose is put into the pool, a large amount of air is retained in the hose. After the water pump intakes the air, cavitation and overheating will occur, thereby causing the components inside the water pump to be damaged by cavitation erosion and shortening the service life. Utility model content

[0005] In order to remove the gas in the water inlet hose of the pool cleaner and improve the problem that the internal components of the water pump are easily damaged by cavitation erosion, the present application provides a cleaner water pipe exhaust device.

[0006] The cleaner water pipe exhaust device provided by the present application adopts the following technical scheme:

[0007] A cleaner water pipe exhaust device, comprising an outer shell, a main pipe body, a first pipe body and a second pipe body, the main pipe body, the first pipe body and the second pipe body are all arranged parallel to the length direction of the outer shell and are all integrally connected to the inside of the outer shell;

[0008] Both ends of the main pipe body are integrally connected with a hose connector and a suction connector, the hose connector and the suction connector are both protrudingly arranged on the outer shell, the inside of the main pipe body, the inside of the hose connector and the inside of the suction connector are all in communication with each other to jointly form a main flow channel, and a blocking element is arranged inside the main flow channel at a position close to the hose connector of the main pipe body;

[0009] The first pipe body is internally provided with a first impeller, and a first impeller flow channel is formed inside the first pipe body. The first pipe body is provided with a pool water inlet at one end of the outer shell body near the hose connector, which is in communication with the first impeller flow channel. The first pipe body is provided with a first impeller outlet on the side wall near the suction connector end, which is in communication with the first impeller flow channel and the main flow channel.

[0010] The second pipe body is internally provided with a second impeller, and the second impeller is rotatably connected with the first impeller. A second impeller flow channel is formed inside the second pipe body. The second pipe body is provided with a second impeller inlet on the pipe wall near the hose connector end, which is in communication with the main flow channel. The second pipe body is provided with a discharge port at one end of the outer shell body near the suction connector.

[0011] By adopting the above technical scheme, the hose connector and the suction connector at both ends of the main pipe body protrude from the outer shell body, which facilitates connection with the water inlet hose and the suction system of the pool cleaner. Moreover, the main pipe body, the hose connector and the suction connector are internally connected with each other to form a main flow channel, which can well adapt to the working process of the pool cleaner and realize the exhaust function without affecting the normal water inlet. The main pipe body, the first pipe body and the second pipe body are all arranged parallel to the length direction of the outer shell body and integrally connected inside the outer shell body, and the compact structure arrangement makes the entire exhaust device more reasonable in space utilization. The first impeller and the second impeller are rotatably connected to work cooperatively. The first impeller is responsible for introducing pool water into the main flow channel and increasing the pressure of the part of the main flow channel near the hose connector, so as to promote the movement of gas to the second impeller flow channel. The second impeller is responsible for discharging gas. The two work cooperatively to complete the exhaust.

[0012] Further, the first pipe body is internally provided with a first gear for driving the first impeller, and the first gear is coaxially arranged and fixedly connected with the first impeller. The second pipe body is internally provided with a second gear for driving the second impeller, and the second gear is coaxially arranged and fixedly connected with the second impeller.

[0013] The first gear and the second gear are meshed with an intermediate gear.

[0014] By adopting the above technical scheme, the first gear is coaxially fixedly connected with the first impeller, the second gear is coaxially fixedly connected with the second impeller, and the intermediate gear is meshed between the first gear and the second gear, so as to build a stable gear transmission system, accurately transmit power, ensure the stable rotation of the first impeller and the second impeller according to the predetermined transmission ratio, guarantee the reliability of the cooperative work of the two, and make them orderly complete a series of actions such as introducing pool water into the main flow channel, promoting the movement of gas and discharging gas, so as to stably realize the exhaust function.

[0015] Further, the central axis direction of the second impeller inlet is perpendicular to the central axis direction of the main flow channel.

[0016] By adopting the above technical scheme, when the central axis direction of the second impeller inlet is perpendicular to the central axis direction of the main flow channel, the water flow in the main flow channel is difficult to directly rush into the second impeller inlet in the normal flow process due to the inconsistent flow directions, thereby effectively reducing the impact of the water flow on the second impeller inlet and avoiding the interference of the water rush into the second impeller inlet with the normal overflow of the gas. Since the water flow is not easy to enter the second impeller inlet, the pressure of the part of the main flow channel close to the hose connector is increased under the action of the first impeller, so that the gas can be squeezed to the second impeller inlet.

[0017] Further, the outer wall of the outer shell body is integrally connected with an external annular pipe for increasing the volume at the corresponding position of the blocking element, the external annular pipe has an outer diameter greater than the outer diameter of the outer shell body, and the intermediate gear is located in the external annular pipe.

[0018] By adopting the above technical scheme, the external annular pipe is located at the corresponding position of the blocking element, and has an outer diameter greater than the outer diameter of the outer shell body. The blocking element hinders the fluid in the main flow channel, so that the pressure at this position changes. The existence of the external annular pipe increases the volume of the main flow channel at this position, so that the gas in the main flow channel has more space to gather. When the first impeller works to increase the pressure of the part of the main flow channel close to the hose connector, the gas can be more effectively compressed and gathered in this volume-increased area, which is beneficial to the subsequent second impeller to discharge the gas. The intermediate gear is located in the external annular pipe, which reasonably utilizes the space increased by the external annular pipe. Since the intermediate gear needs to be engaged and driven between the first gear and the second gear, the arrangement of this space can avoid the interference between the intermediate gear and other components.

[0019] Further, the outer shell body is provided with a timing device for controlling the opening and closing of the blocking element at the adjacent position of the second gear.

[0020] By adopting the above technical scheme, the timing device can control the opening and closing of the blocking element according to the preset time law according to the working state and actual needs of the pool cleaner. When the pool cleaner just starts to work, the timing device can open the blocking element to allow the water to smoothly pass through the main pipe body, so that the entire device quickly enters the normal working state. When a period of time has passed, it is estimated that most of the gas in the water inlet hose has been introduced into the main flow channel by the first impeller and gathered near the blocking element, and the timing device can close the blocking element, which can effectively seal the gas in a specific area of the main flow channel, facilitating the second impeller to discharge the gas from the discharge port.

[0021] Further, the blocking element is a butterfly valve.

[0022] By adopting the above technical scheme, the butterfly valve has good sealing performance and a relatively simple structure, mainly composed of a valve body, a valve plate, a valve rod and the like. The butterfly valve can accurately control the flow of fluid in the main pipe body as a blocking element. The butterfly valve adjusts the opening size by rotating the valve plate. When the timing device controls the opening of the butterfly valve, the opening degree can be flexibly adjusted according to actual needs, so that water can smoothly pass through the main pipe body at a suitable flow rate.

[0023] Further, the timing device is a gear timer.

[0024] By adopting the above technical scheme, the gear timer performs timing based on a mechanical gear structure, and has better mechanical stability than an electronic timing device. In the environment of pool cleaning, which may be in contact with water, has a certain humidity and disinfectant and other chemicals, electronic components may be corroded or interfered and malfunction, while the gear timer can provide accurate timing function. In the working process of the pool cleaner, it can accurately control the opening and closing of the blocking element according to the pre-set time interval or working stage, determine the time point of opening the butterfly valve when the pool cleaner starts to work, and the time point of closing the butterfly valve after a period of time.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. The hose connector and suction connector of the main pipe body protrude from the outer shell, facilitating connection with the water inlet hose and the suction system, while the internal communication of the main pipe body and the like forms a main flow channel, adapts to the working process of the pool cleaner, completes the exhaust without affecting the normal water inlet, and ensures stable and efficient operation of the pool cleaning system;

[0027] 2. The compact structure of the parallel and integral connection of the main pipe body, the first pipe body and the second pipe body improves the space utilization. The first impeller and the second impeller work cooperatively through gear transmission, cooperate with the external ring pipe to increase the local volume of the main flow channel, provide reasonable arrangement space for the intermediate gear, effectively avoid component interference, promote the efficient exhaust of gas from the main flow channel, improve the exhaust efficiency and ensure the stable operation of the whole device;

[0028] 3. The timing device can control the opening and closing of the blocking element according to the pre-set time rule according to the working state of the pool cleaner and actual needs, which can not only ensure the smooth passage of water through the main pipe body when starting to work to make the device quickly enter the normal state, but also close the gas at the right time to facilitate more efficient exhaust, optimize the exhaust process and further improve the overall exhaust effect.

The outer ring pipe 11 is located at one end of the outer shell 1 close to the hose connector 21.

[0041] Referring to Figure 4 , the inside of the main pipe body 2, the inside of the hose connector, and the inside of the suction connector 22 are in communication with each other to jointly form a main flow channel 23. In combination Figure 6 and Figure 7 , the main flow channel 23 is provided with a blocking element 5 at a position close to the hose connector 21 of the main pipe body 2. The blocking element 5 in the embodiment is preferably a butterfly valve, and the blocking element 5 can be used to control the opening and closing of the main flow channel 23.

[0042] The first pipe body 3 is rotatably connected with a first impeller 31, and the first impeller 31 is coaxially provided with a first gear 32 at a position of the outer ring pipe 11. The first pipe body 3 forms a first impeller flow channel 33 inside, and the first pipe body 3 is provided with a pool water inlet 34 at one end close to the hose connector 21 of the outer shell 1. The pool water inlet 34 is in communication with the first impeller flow channel 33. The first pipe body 3 is provided with a first impeller outlet 35 at a side wall close to the suction connector 22, and the first impeller outlet 35 is in communication with the first impeller flow channel 33 and the main flow channel 23.

[0043] Referring to Figure 5 , the second pipe body 4 is rotatably connected with a second impeller 41, and the second impeller 41 is coaxially provided with a second gear 42 at a position of the outer ring pipe 11. The second pipe body 4 forms a second impeller flow channel 43 inside, and the second pipe body 4 is provided with a second impeller inlet 44 at a pipe wall close to the hose connector 21. The second impeller inlet 44 is in communication with the main flow channel 23. The second pipe body 4 is provided with a discharge port 45 at one end close to the suction connector 22 of the outer shell 1. In combination Figure 8 , the first gear 32 and the second gear 42 are engaged with an intermediate gear 12, and the outer ring pipe 11 can provide space for the installation and rotation of the intermediate gear 12.

[0044] The outer ring pipe 11 is further provided with a timing device 51 at a position adjacent to the second gear 42 inside. The timing device 51 can be used to control the amount of time for which the blocking element 5 blocks the flow of fluid through the main flow channel 23. The timing device 51 can be implemented in various mechanisms, such as a spring timer, an electronic timer, or a gear timer. The timing device 51 in the embodiment is preferably a gear timer, and the gear of the timing device 51 can be driven by any one of the first gear 32, the second gear 42, or the intermediate gear 12.

[0045] The principle of the cleaner water pipe exhaust device is as follows: when the device is placed in a swimming pool, the hose connector 21 is connected to one end of the flexible hose, and the suction connector 22 is connected to the suction connection port of the swimming pool recirculation system. The blocking element 5 is set to block the main flow passage 23 in the initial state.

[0046] When the main flow passage 23 is blocked, the suction force is applied through the suction connector 22, and the pool water is sucked to the position of the suction connector 22 through the pool water inlet 34, the first impeller flow passage 33 and the first impeller outlet 35, at which time the water flow drives the first impeller 31 to rotate.

[0047] The first gear 32 and the second gear 42 are engaged with the intermediate gear 12, so that the rotation of the first impeller 31 drives the second impeller 41 to rotate. When the gear sizes between the first gear 32, the second gear 42 and the intermediate gear 12 change, the torque is increased, and the rotation speed of the second impeller 41 is controlled to be lower than that of the first impeller 31. The rotation of the second impeller 41 can generate suction at the position of the hose connector 21, so that air (and part of the pool water) is sucked out of the flexible hose through the second impeller inlet 44 and flows out of the discharge port 45 through the flow passage of the second impeller 41.

[0048] After a period of time, the blocking element 5 is opened by the timing device 51, so that the water flow can pass through the main flow passage 23 between the hose connector and the suction connector 22, and the pool water is blocked from passing through the first impeller flow passage 33, thereby stopping the rotation of the first impeller 31 and the second impeller 41.

[0049] By setting the time period of the timing device 51, it can be ensured that all trapped air is discharged. When a fixed time is used, the specific length of the fixed time period needs to be determined according to parameters such as the length of the hose and the flow rate of the pool pump. When an adjustable time period is used, the parameters are set by the operator.

[0050] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
