Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a swimming pool cleaning robot. 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, due to the large water storage capacity in the swimming pool, 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 robots were created. Traditional swimming pool cleaning robots greatly save labor costs. The debris and sediment where they pass are well cleaned, and the swimming pool cleaning robots can perform continuous operations in the swimming pool.

[0003] The swimming pool cleaning robot mainly works by pumping water to suck in 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 pool cleaning robot includes a cable and a float, and the float communicates with the pool cleaning robot through the cable. However, when the pool cleaning robot is cleaning the pool surface, the cable is too long, which will greatly affect the cleaning work of the pool cleaning robot. It is also inconvenient to fold up, affecting the user's storage and reducing the user experience. Utility Model Content

This prevents the pool cleaning robot from becoming entangled in the cable during surface cleaning due to an overly long cable, thereby facilitating the normal operation of the pool cleaning robot.

[0011] Furthermore, the floating and sinking mechanism includes:

[0012] A floating chamber, the floating chamber being arranged in the machine body;

[0013] a connecting pipe, one end of which is connected to the floating chamber and the other end of which is located outside the body;

[0014] A driving member is connected to the connecting pipe, and the driving member is used to add water to the floating chamber through the connecting pipe to increase the weight of the floating chamber, thereby causing the body to sink to the bottom of the pool, or the driving member is used to drain water from the floating chamber through the connecting pipe to reduce the weight of the floating chamber, thereby causing the body to float to the surface of the pool.

[0015] Furthermore, the driving member is a peristaltic pump.

[0016] Furthermore, there are two peristaltic pumps.

[0017] Furthermore, the swimming pool cleaning robot also includes a signal transceiver device, and the signal transceiver device is arranged in the float.

[0023] Rotate the motor;

[0024] The rotating part is fixedly connected to the rotating motor, and the cable is fixedly connected to the rotating part. The rotating motor is used to drive the rotating part to rotate. When the rotating motor rotates in the forward direction, the rotating part retracts the cable into the wire accommodating cavity, or when the rotating mechanism rotates in the reverse direction, the rotating part releases the cable.

[0025] Furthermore, the contact portion between the cable and the housing is movably sealed.

[0026] Furthermore, a floating plate is provided on the surface of the float, and the floating plate is used to increase the buoyancy of the float so that the float can float stably on the surface of the pool.

[0037] See also Figure 1 A swimming pool cleaning robot 100 is provided. The swimming pool cleaning robot 100 includes:

[0038] The body 10 includes a floating and sinking mechanism (not shown) for controlling the pool cleaning robot 100 to sink to the bottom of the pool for cleaning or to float on the surface of the pool for cleaning;

[0039] The float assembly 20 includes a float 201 and a cable 202 connected to the float 201. One end of the cable 202 is connected to the float 201, and the other end of the cable 202 is connected to the body 10. The body 10 is connected to the external communication device through the cable 202 and the float 201.

[0040] The automatic winding wire assembly 30 is arranged on the body 10 , and one end of the cable 202 is fixedly connected to the automatic winding wire assembly 30 . The automatic winding wire assembly 30 is used to release the cable 202 or to retract the cable 202 to adjust the length of the cable 202 .

[0041] The pool cleaning robot 100 of the present invention utilizes a floating mechanism, allowing it to automatically sink to the bottom of the pool for cleaning or float on the surface. This allows the pool cleaning robot 100 of the present invention to perform both underwater and surface cleaning functions, enhancing its functionality. The float assembly 20 allows the pool cleaning robot 100 to communicate with external devices even underwater, facilitating user access to the robot's operating status and enhancing its intelligence. The automatic cable reel assembly 30 releases the cable 202 when the robot 100 sinks, and retracts it when it rises to the surface. This prevents the robot 100 from becoming entangled in the cable 202 during surface cleaning due to excessive length, facilitating proper operation of the robot 100.

[0042] As can be seen from the above, the main function of the cable 202 of the pool cleaning robot 100 is to transmit signals. Since underwater signals are very weak and have poor stability, signal transmission abnormalities are very likely to occur through wireless connection. The provision of the cable 202 can achieve stable signal transmission. However, due to the long length of the cable 202, when the pool cleaning robot 100 floats on the surface of the pool to clean the pool surface, the cable 202 will affect the operation of the pool cleaning robot 100. The cable 202 may even be sucked into the water inlet of the pool cleaning robot 100, causing damage to the pool cleaning robot 100. The pool cleaning robot 100 in the embodiment of the present invention, through the provision of the automatic winding cable assembly 30, can retract the cable 202 into the automatic winding cable assembly 30 during the process of the pool cleaning robot 100 floating up, thereby avoiding the above situation, improving the intelligence of the pool cleaning robot 100, and making it more convenient for users to use.

[0043] Among them, the body 10 is made of plastic, which has the advantage of strong plasticity, which is conducive to the molding and 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.

[0044] Furthermore, a signal transceiver is provided in the float 201, and the signal transceiver can be used to connect with an external communication device, thereby realizing the sending and receiving of signals, which is convenient to operate and easy to implement.

[0045] Among them, the external communication device can be an electronic device such as a mobile phone, computer, tablet, etc.

[0046] Furthermore, the floating and sinking mechanism includes:

[0047] A floating chamber is provided in the body 10;

[0048] A connecting pipe, one end of which is connected to the floating chamber and the other end of which is located outside the body 10;

[0049] The driving member is connected to the connecting pipe, and the driving member is used to add water to the floating chamber through the connecting pipe to increase the weight of the floating chamber, so that the body 10 sinks to the bottom of the pool, or the driving member is used to drain water from the floating chamber through the connecting pipe to reduce the weight of the floating chamber, so that the body 10 floats to the surface of the pool.

[0050] That is to say, the swimming pool cleaning robot 100 of the embodiment of the present invention is provided with a floatation chamber, a connecting pipe and a driving member. One end of the connecting pipe is connected to the floatation chamber, and the other end of the connecting pipe is connected to the outside of the body 10. The driving member can flush water into the floatation chamber or discharge the water in the floatation chamber to the outside of the body 10 through the connecting pipe, thereby changing the weight of the floatation chamber, and then changing the weight of the swimming pool cleaning robot 100, thereby changing the buoyancy of the swimming pool cleaning robot 100 to achieve the floating or sinking of the swimming pool cleaning robot 100. The structure is simple and easy to implement.

[0051] Furthermore, the driving element is a peristaltic pump.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Low shear force: Suitable for conveying shear-sensitive and highly corrosive fluids without damaging solid matter in the fluid.

[0056] Good sealing: It has good self-priming ability and anti-backflow function, without valves and other seals, reducing leakage and maintenance problems.

[0057] Simple maintenance: Except the pump tube, there are no other parts that require special maintenance, and the pump tube can be replaced easily.

[0058] Bidirectional conveying: forward and reverse flow can be achieved to meet the needs of specific process.

[0059] Adaptable to idling and dry operation: it can operate without liquid, and can also transport air or gas-liquid-solid three-phase mixture.

[0060] Self-priming capability: It can self-prime and transfer liquids without priming and emptying the pump.

[0061] Corrosion resistance: Pump tubes made of corrosion-resistant materials can be selected, which are suitable for conveying corrosive liquids.

[0062] Wide range of applications: It can replace pump tubes of different materials and is suitable for a variety of industries and media.

[0063] 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.

[0064] Furthermore, the number of the peristaltic pumps is two.

[0065] The setting of two peristaltic pumps can improve the efficiency of gas transportation, which is conducive to the rapid filling or drainage of water in the floating chamber.

[0066] 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.

[0067] See also Figure 1 Furthermore, the automatic winding line assembly 30 includes:

[0068] The housing 301 has a wire cavity 3011 formed therein, and the cable 202 at least partially passes through the housing 301 and is exposed on the surface of the housing 301;

[0069] The rotating mechanism 40 is located in the wire accommodating cavity 3011 , and one end of the cable 202 is fixedly connected to the rotating mechanism 40 . The rotating mechanism 40 rotates forward to retract the cable 202 into the wire accommodating cavity 3011 , or rotates backward to release the cable 202 .

[0070] In the embodiment of the present invention, the rotating mechanism 40 can realize forward rotation and reverse rotation, thereby realizing the retraction or release of the cable 202. Only one mechanism is needed to realize the above functions, and the operation is simple and easy to realize.

[0071] The provision of the wire accommodating cavity 3011 facilitates the collection of the cables 202 .

[0072] Among them, the shell 301 is made of plastic, which has the advantage of strong plasticity, which is conducive to the molding and design of the shell 301. Of course, in other embodiments, the shell 301 can also be made of other materials, and the specific design can be based on actual conditions, which is not limited here.

[0073] Please see here Figure 1 , further, the rotating mechanism 40 includes:

[0074] Rotating motor 401;

[0075] The rotating part 402 is fixedly connected to the rotating motor 401, and the cable 202 is fixedly connected to the rotating part 402. The rotating motor 401 is used to drive the rotating part 402 to rotate. When the rotating motor 401 rotates forward, the rotating part 402 retracts the cable 202 into the wire accommodating cavity 3011, or when the rotating mechanism 40 rotates reversely, the rotating part 402 releases the cable 202.

[0076] By setting the rotating motor 401 and the rotating part 402, the rotating motor 401 drives the rotating part 402 to rotate, and the rotating part 402 can be used to retract the cable 202. In other words, only the rotating motor 401 needs to work to realize the retraction and release of the cable 202 through the rotating part 402. The structure is simple and easy to implement.

[0077] Furthermore, the contact portion between the cable 202 and the housing 301 is movably sealed.

[0078] In the embodiment of the present invention, the movable seal refers to an oil seal treatment. Since a rotating motor 401 is provided in the housing 301, the oil seal treatment can prevent water in the pool from entering the housing 301 and thus preventing the rotating motor 401 from being damaged by water. This is beneficial to the operation of the pool cleaning robot 100 and can also extend the service life of the pool cleaning robot 100.

[0079] Furthermore, a floating plate (not shown) is provided on the surface of the float ball 201, and the floating plate is used to increase the buoyancy of the float ball 201 so that the float ball 201 can float stably on the surface of the pool.

[0080] From the above, it can be seen that the cable 202 can be released and retracted through the automatic winding wire assembly 30, and the buoyancy of the float 201 can be increased through the setting of the floating plate, avoiding the situation where the float 201 is pulled when the automatic winding wire assembly 30 is working, thereby improving the stability of the float 201.

[0081] Furthermore, running wheels 50 are provided at the bottom of the pool cleaning robot 100 , and the running wheels 50 are used to drive the pool cleaning robot 100 to move on the bottom of the pool.

[0082] By providing the running wheels 50 , the swimming pool cleaning robot 100 can move on the bottom of the pool, thereby going to different areas to perform cleaning operations. The structure is simple and easy to implement.

[0083] 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.
