Description

Technical Field

[0001] The utility model relates to the field of swimming pool cleaning devices, in particular to a swimming pool cleaning device. Background Art

[0002] As people pay more and more attention to health, swimming has been sought after by young people as a very good form of fitness exercise. For this reason, more and more swimming pools have been built. However, since the water storage in the swimming pool is relatively large, the cost of frequent replacement is too high. Therefore, people often use sedimentation to deal with impurities. This method causes impurities to form sediments and accumulate at the bottom of the swimming pool. Subsequently, manual or machine cleaning of the sediment at the bottom of the swimming pool is required. For this reason, swimming pool cleaning devices have been created. Traditional swimming pool cleaning devices greatly save labor costs. The debris and sediment in the places where they pass are well cleaned, and the swimming pool cleaning device can perform continuous operations in the swimming pool.

[0003] The swimming pool cleaning device mainly uses a water pump to suck water from the bottom, and also sucks in debris and sand at the bottom of the pool. A filter is installed inside the machine, and the water is filtered and discharged from the outlet.

[0004] However, the existing swimming pool cleaning device does not have the ability to clean the water surface, the bottom of the water, and the water at the same time, and only has a single cleaning ability, which greatly affects the cleaning efficiency of the swimming pool cleaning device and is not conducive to user use. Utility Model Content

[0005] Based on this, it is necessary to provide a swimming pool cleaning device to address the above technical problems, so as to solve the problem that the swimming pool cleaning devices in the prior art have relatively single functions.

[0007] The body is provided with a floating chamber, which is detachably connected to the body and is designed as an integral part. The floating chamber is used to adjust the overall weight of the body to control the body to sink to the bottom of the pool or float on the surface of the pool;

[0008] a float assembly connected to the machine body, comprising a connecting line and a float ball, an air tube provided in the connecting line, an air port provided on the float ball, one end of the air tube being in communication with the air port, and the other end of the air tube being in communication with the floating chamber when the connecting line is mounted on the machine body;

[0009] a driving member, the driving member being used to apply airflow to the air pipe to evacuate the air in the floating chamber to create a negative pressure state in the floating chamber so that external water can automatically flow into the floating chamber, or to apply air to the floating chamber to discharge the water in the floating chamber to the outside of the floating chamber;

When the driving member extracts air from the floating chamber, a vacuum state will appear in the floating chamber. In this way, the water in the pool will enter the inside of the floating chamber, thereby increasing the overall weight of the swimming pool cleaning device, thereby allowing the swimming pool cleaning device to sink into the swimming pool. With such an arrangement, the swimming pool cleaning device can float on the surface of the swimming pool to clean the surface of the swimming pool, and can also sink to the bottom of the swimming pool to clean the bottom of the swimming pool; through the arrangement of the suspension component, in combination with the arrangement of the floating bin, the float component and the driving component, when the machine needs to be suspended in the swimming pool, through the forward and reverse correction of the suspension component and the driving component, the suspension component provides an upward thrust to the swimming pool cleaning device, and the driving component adjusts the weight of the swimming pool cleaning device to adjust the buoyancy of the swimming pool cleaning device, so that the machine remains suspended at a relatively stable water layer height for operation, thereby enabling the swimming pool cleaning device to have the three cleaning functions of the pool surface, the pool bottom and the pool, thereby improving the cleaning efficiency of the swimming pool cleaning device and facilitating the use of the user.

[0034] See also Figures 1 to 3 A swimming pool cleaning device 100 is provided. The swimming pool cleaning device 100 includes:

[0035] The body 10 includes a floating chamber 20 disposed therein. The floating chamber 20 is detachably connected to the body 10 and is integrally formed. The floating chamber 20 is used to adjust the overall weight of the body 10 to control the body 10 to sink to the bottom of the pool or float on the surface of the pool.

[0036] The float assembly 30 is connected to the body 10 and includes a connecting line 302 and a float ball 301. An air tube is provided in the connecting line 302, and an air port is provided on the float ball 301. One end of the air tube is connected to the air port. When the connecting line 302 is installed in the body 10, the other end of the air tube is connected to the floating chamber 20.

[0037] A driving member (not shown) is used to apply airflow to the air pipe to evacuate the air in the floating chamber 20 to create a negative pressure state in the floating chamber 20 so that external water can automatically flow into the floating chamber 20, or to apply air to the floating chamber 20 to discharge the water in the floating chamber 20 to the outside of the floating chamber 20;

[0038] The suspension component 50 is arranged in the body 10 and is parallel to the height direction of the body 10. The suspension component 50 is used to drain water to the bottom of the body 10 to provide an upward thrust to the body 10, so that the body 10 is suspended in the middle of the pool.

[0039] The swimming pool cleaning device 100 of the present invention is provided with a floating chamber 20, a float assembly 30 and a driving member. The floating member includes an air pipe. The floating chamber 20 is connected to the external air through the air pipe and the float ball 301. Through the operation of the driving member, air can be added to the floating chamber 20 through the air pipe or the air in the floating chamber 20 can be discharged to the outside of the float ball 301. When the driving member applies air to the floating chamber 20, the water in the floating chamber 20 will be discharged to the outside of the floating chamber 20 under the pressure of the air, so as to reduce the overall weight of the swimming pool cleaning device 100, so that the swimming pool cleaning device 100 can float on the surface of the swimming pool. When the driving member extracts air from the floating chamber 20, a vacuum state will appear in the floating chamber 20. In this way, the water in the pool will enter the inside of the floating chamber 20, so as to increase the overall weight of the swimming pool cleaning device 100, so that the swimming pool cleaning device 100 can sink to the bottom of the swimming pool. With this arrangement, the swimming pool cleaning device 100 can both float and The swimming pool cleaning device 100 can clean the swimming pool surface from the swimming pool surface and can also sink to the bottom of the swimming pool to clean the swimming pool bottom, thereby enabling the swimming pool cleaning device 100 to have the dual cleaning functions of the swimming pool surface and the bottom of the swimming pool, thereby improving the cleaning efficiency of the swimming pool cleaning device 100 and facilitating the use of the user; by providing the suspension component 50, in conjunction with the floating chamber 20, the float component 30 and the driving component, when the machine needs to be suspended in the swimming pool, the suspension component 50 and the driving component rotate forward and reverse, and the suspension component 50 provides an upward thrust to the swimming pool cleaning device 100. The driving component adjusts the weight of the swimming pool cleaning device 100 to adjust the buoyancy of the swimming pool cleaning device 100, thereby allowing the machine to remain suspended at a relatively stable water layer height during operation, thereby enabling the swimming pool cleaning device 100 to have the triple cleaning functions of the swimming pool surface, the pool bottom and the swimming pool, thereby improving the cleaning efficiency of the swimming pool cleaning device 100 and facilitating the use of the user.

[0040] When the pool cleaning device 100 needs to be suspended for operation, if the pool cleaning device 100 is located on the water surface, the driving member starts to rotate forward and exhausts the floating chamber 20 through the air pipe. At this time, the floating chamber 20 is in a negative pressure state, and the water in the pool will automatically enter the floating chamber 20. By setting the amount of exhaust, the pool cleaning device 100 will gradually sink and be in a semi-suspended state. At this time, the suspension component 50 starts to work. Combined with the liquid level pressure value currently detected by the pool cleaning device 100, the suspension component 50 and the driving member are continuously corrected in forward and reverse rotation, so that the pool cleaning device 100 can remain suspended at a relatively stable water layer height for operation; of course, if the pool cleaning device 100 is initially located at the bottom of the water, the driving member will reverse to inflate the floating chamber 20, thereby achieving suspension of the pool cleaning device 100.

[0041] Furthermore, the body 10 is made of plastic, which has the advantage of strong plasticity, which is beneficial to the design of the body 10. Of course, in other embodiments, the body 10 can also be made of other materials, and the specific design can be based on actual conditions, which is not limited here.

[0042] In the embodiment of the present invention, the floatation tank 20 is located within the body 10 and is integrated with the body 10. Therefore, the weight of the floatation tank 20 directly affects the weight of the entire pool cleaning device 100. By draining the water in the floatation tank 20 to reduce the weight of the entire pool cleaning device 100, the pool cleaning device 100 floats on the surface of the pool, thereby enabling the pool cleaning device 100 to clean the pool surface. Alternatively, by adding water to the floatation tank 20 to increase the weight of the entire pool cleaning device 100, the pool cleaning device 100 sinks to the bottom of the pool, thereby enabling the pool cleaning device 100 to clean the pool bottom. This operation is relatively simple and easy to implement.

[0043] It should be noted that in the embodiment of the present invention, the floating chamber 20 is connected to the external air through the connecting line 302 of the float assembly 30, and then the driving component is used to supply air to the floating chamber 20 or to vacuum the floating chamber 20. This arrangement is used to control the outflow or inflow of water in the floating chamber 20. The structure is simple and easy to implement.

[0044] It should be noted that when the floating bin 20 is full of water, the floating bin 20 acts as a counterweight, thereby enabling the swimming pool cleaning device 100 to sink to the bottom of the swimming pool. When there is no water in the floating bin 20, it can drive the swimming pool cleaning device 100 to float to the surface of the swimming pool.

[0045] Specifically, the floating bin 20 is made of plastic. As can be seen from the above, plastic has strong plasticity and is light in weight, which is conducive to the styling design of the floating bin 20. It can be understood that in other embodiments, the floating bin 20 can also be made of other materials, which can be considered according to actual conditions and is not limited here.

[0046] See also Figure 3 , further, the suspension assembly 50 includes:

[0047] Drive motor 501;

[0048] The blade 502 is fixedly connected to the rotating shaft of the driving motor 501 , and the driving motor 501 is used to drive the rotating shaft to rotate so as to drive the blade 502 to rotate.

[0049] The drive motor 501 can drive the blades 502 to rotate, so that the drive motor 501 and the blades 502 are superimposed to form a propeller. The propeller converts mechanical energy into thrust. In the embodiment of the utility model, the drive motor 501 drives the blades 502 to rotate. The rotation of the blades 502 causes the water to spiral. The reaction force generated by the spiral gives the pool cleaning device 100 an upward thrust to offset the gravity of the pool cleaning device 100, thereby allowing the pool cleaning device 100 to float in the water and clean garbage in the water. The structure is simple and easy to implement.

[0050] In the embodiment of the present invention, the driving motor 501 is an AC motor.

[0051] AC motors offer high energy conversion efficiency, low maintenance costs, and environmental friendliness, resulting in a certain degree of durability. Furthermore, AC motors operate smoothly, are easy to start and control, and utilize both natural cooling and forced ventilation to effectively improve motor efficiency.

[0052] Furthermore, induction motors have a simpler structure and, because they lack brushes, have a lower failure rate. Their design also results in relatively low maintenance costs and less frequent service during load adjustments. Furthermore, AC motors can be used in a variety of environments without concerns about inter-electrode short circuits or insulation loss, resulting in more stable and reliable operation.

[0053] Of course, in other embodiments, the driving motor 501 may also be a DC motor, which can be specifically designed according to actual conditions and is not limited here.

[0054] See also Figure 3Furthermore, a mounting channel 60 is formed in the body 10 , and the mounting channel 60 is arranged along the height direction of the body 10 . An opening 601 is provided at the bottom of the mounting channel 60 , and the mounting channel 60 is communicated with the outside through the opening 601 .

[0055] By setting the installation channel 60 and the opening 601, the water flow can be gathered in the installation channel 60, so that the rotation of the blade 502 can drive the water in the installation channel 60 into a spiral shape, thereby generating a reverse force, and through this directional force, an upward thrust is given to the pool cleaning device 100.

[0056] The projection of the opening 601 on the plane is a circle.

[0057] See also Figure 3 Furthermore, the body 10 includes a motor waterproof housing 70, the motor waterproof housing 70 is arranged in the installation channel 60, the drive motor 501 is arranged in the motor waterproof housing 70, the rotating shaft is partially exposed from the motor waterproof housing 70 and is connected to the blade 502, and the part where the rotating shaft contacts the motor waterproof housing 70 is movable and sealed.

[0058] By providing the motor waterproof housing 70 , the driving motor 501 can be protected, thereby preventing the driving motor 501 from being damaged by water in the swimming pool, thereby extending the life of the swimming pool cleaning device 100 .

[0059] The movable seal may be an oil seal. Of course, in other embodiments, other sealing methods may also be used. The specific design may be based on actual conditions and is not limited here.

[0060] Furthermore, the float assembly 30 is detachably connected to the body 10 .

[0061] As can be seen from the above, the swimming pool cleaning device 100 according to the embodiment of the present invention includes a float assembly 30, which includes a float ball 301 and a connecting line 302. When the swimming pool cleaning device 100 is in operation, the float ball 301 floats on the water surface, and the swimming pool cleaning device 100 performs cleaning underwater. When the swimming pool cleaning device 100 is cleaning the water surface, the connecting line 302 is likely to float on the water surface. In such a situation, it is easy to affect the cleaning of the swimming pool surface by the swimming pool cleaning device 100. For example, the connecting line 302 is entangled in the interior of the swimming pool cleaning device 100. The float assembly 30 is detachably connected to the body 10. With this arrangement, when the swimming pool cleaning device 100 is cleaning the water surface, the float assembly 30 can be removed from the swimming pool cleaning device 100 to avoid the above-mentioned situation.

[0062] The specific detachable connection can be a snap connection.

[0063] See also Figures 1 to 3Furthermore, a mounting portion 303 is provided at one end of the connecting line 302 away from the float 301 , and a mounting groove 40 is provided on the body 10 , and the mounting portion 303 is engaged with the mounting groove 40 to connect the connecting line 302 to the body 10 .

[0064] The arrangement of the mounting portion 303 and the mounting groove 40 facilitates the connection between the float assembly 30 and the body 10 , and the structure is simple and easy to implement.

[0065] Furthermore, an O-ring is provided on the mounting portion 303 , and the float assembly 30 is sealedly connected to the body 10 via the O-ring.

[0066] By providing the O-ring, when the float assembly 30 is installed on the body 10 , the connection line 302 and the body 10 can be waterproofed, thereby improving the waterproof performance of the swimming pool cleaning device 100 .

[0067] Among them, the number of O-rings is two.

[0068] Of course, in other embodiments, the number of O-rings may be other numbers, which can be designed according to actual conditions and is not limited here.

[0069] Furthermore, the driving element is a peristaltic pump.

[0070] Specifically, the advantages of peristaltic pumps include no pollution, high precision, low shear force, good sealing, simple maintenance, bidirectional delivery, adaptability to idling and dry running, self-priming ability, corrosion resistance and a wide range of applications.

[0071] No pollution: The fluid only contacts the pump tube and does not contact other parts inside the pump body. It is suitable for handling media that are easily contaminated, such as liquid transportation in the food and pharmaceutical industries.

[0072] High precision: high repeatability and stability, suitable for applications requiring precise metering. Accurate metering and control can be achieved by adjusting the speed and frequency of the pump.

[0073] Low shear force: suitable for conveying shear-sensitive and corrosive fluids without damaging solid matter in the fluid.

[0074] Good sealing: It has good self-priming ability and anti-backflow function, without valves and other seals, reducing leakage and maintenance problems.

[0075] Simple maintenance: Except the pump tube, there are no other parts that require special maintenance, and the replacement of the pump tube is simple.

[0076] Bidirectional conveying: forward and reverse flow can be achieved to meet the needs of specific process.

[0077] Adaptable to idling and dry operation: it can operate without liquid, and can also transport air or gas-liquid-solid three-phase mixture.

[0078] Self-priming capability: It can self-prime and transfer liquids without priming and emptying the pump.

[0079] Corrosion resistance: Pump tubes made of corrosion-resistant materials can be selected, which are suitable for conveying corrosive liquids.

[0080] Wide range of applications: It can replace pump tubes of different materials and is suitable for a variety of industries and media.

[0081] Therefore, a peristaltic pump is a better choice for the driving member. Of course, in other embodiments, other driving devices can also be used. The specific design can be based on actual conditions and is not limited here.

[0082] Furthermore, the number of the peristaltic pumps is two.

[0083] The provision of two peristaltic pumps can improve the efficiency of gas delivery, which is conducive to achieving rapid water inflow or water outflow of the floating chamber 20.

[0084] In other embodiments, the number of peristaltic pumps may be other numbers, which can be considered based on actual conditions and is not limited here.

[0085] Furthermore, the swimming pool cleaning device 100 further includes four moving wheels, which are mounted on the bottom of the swimming pool cleaning device 100 , and a plurality of grooves are formed on the surfaces of the moving wheels.

[0086] By providing the movable wheels, the pool cleaning device 100 can be moved to clean different areas. By providing grooves on the surface of the walking wheels, the friction of the walking wheels can be increased, thereby preventing the pool cleaning device from excessively slipping, which is conducive to the normal operation of the pool cleaning device 100.

[0087] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the scope of protection of the present invention.
