Description

Technical Field

[0001] The utility model relates to the technical field of intelligent cleaning equipment, in particular to a swimming pool cleaning equipment, in particular to a swimming pool cleaning robot. Background Art

[0002] In recent years, pool robots, as a professional pool cleaning device, have become increasingly popular and increasingly important in the pool cleaning field. This is particularly true in private and public pools, where they save labor costs and perform repeatable daily tasks. Consequently, they have become the preferred cleaning equipment for pool cleaning.

[0003] However, existing pool cleaning equipment requires full and prolonged immersion in water. During operation, underwater robots are subject to vibrations, water bubbles, and other factors, which can cause the liquid filtration unit (or "filter basket") to fail or deteriorate, resulting in the filtration unit (or "filter basket") falling off the pool cleaning equipment.

[0004] The installation methods and installation disadvantages of the liquid filter unit (filter basket) of general pool cleaning equipment are as follows:

[0005] 1. The liquid filter unit (filter basket) is installed inside the housing of the pool cleaning device. In this structure, the pool cleaning device needs to be fixed or pressed inside the housing with a cover or other structure, making it difficult to move during operation. In this structure, the addition of the cover makes the structure complicated, and the user needs to open the cover and then lift the liquid filter unit (filter basket) during the cleaning process. The operation is complicated, and the user's hands directly touch the liquid filter unit (filter basket) when lifting it, which is unhygienic and lacks a good user experience.

[0006] 2. A cavity is provided on the housing of the pool cleaning equipment, and the liquid filter unit (filter basket) is directly placed on the cavity. This structure makes it very convenient to lift the liquid filter unit (filter basket) after cleaning, but the connection between the liquid filter unit (filter basket) and the housing is unstable. Therefore, some manufacturers fix the liquid filter unit (filter basket) and the housing by providing clips. However, the pool cleaning equipment is in an underwater environment, where a large amount of sand and dust will accumulate in the gaps between the clips. As a result, the liquid filter unit (filter basket) is affected by sand and other particles during installation and removal, making it difficult to lift or improperly installed.

[0007] Therefore, how to make the swimming pool cleaning equipment both easy and quick to lift the liquid filter unit (filter basket) and have a good fixing method, etc., is a technical problem that the industry urgently needs to solve. Utility Model Content

[0008] The utility model aims to overcome the deficiencies in the prior art and provide a swimming pool cleaning device for solving the problems of the existing swimming pool cleaning device such as complicated operation, unstable structure, difficulty in lifting or improper installation.

[0031] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0032] Example 1

[0033] like Figure 1-4 As shown, this embodiment provides a swimming pool cleaning device. In this embodiment, the swimming pool cleaning device specifically refers to a swimming pool cleaning robot, which includes:

[0034] The housing 1 includes at least one interconnected water inlet 2 and at least one interconnected water outlet 3. A housing 11 is provided on or within the housing 1, connecting both the water inlet 2 and the water outlet 3. The housing 11 can accommodate a liquid filtration unit 4 in the form of a filter chamber, filter basket, or filter bag. Pool water enters through the water inlet 2, flows through the liquid filtration unit 4, and coarse particles and waste remain within the filtration unit. The filtered liquid then flows out of the water outlet 3, thereby cleaning the pool water. In this embodiment, the housing 1 refers to the outer shell 1 of the pool cleaning device.

[0035] A liquid suction unit (a water pump in this embodiment, not shown) is disposed within the housing 1 and is used to guide liquid from the water inlet 2 to the water outlet 3. In this embodiment, the liquid suction unit is preferably a water pump, which may also be an axial-flow water pump. It is electrically connected to the battery, main control circuit, and other components within the pool cleaning device to power and control the water pump.

[0036] Liquid filtration unit 4 is used to filter liquid flowing from the water inlet 2 to the water outlet 3. Liquid filtration unit 4 is detachable or removable relative to the housing 1 and is at least partially or entirely disposed within the accommodating chamber 11. Liquid filtration unit 4 primarily performs coarse filtration of the liquid in the swimming pool, primarily filtering waste, fallen leaves, dead insects, coarse particles, and animal hair. In this embodiment, the liquid filtration unit refers to a filter basket.

[0037] like Figure 1 As shown, in this embodiment, part of the housing 1 can also be disposed on the liquid filter unit 4, and the water outlet 3 can also be disposed on the upper portion of the liquid filter unit 4. During implementation, liquid enters from the water inlet 2 at the bottom, flows through the liquid filter unit 5, and is then discharged from the water outlet 4 disposed on the upper portion of the liquid filter unit 5. This achieves the same technical effect.

[0038] Since the garbage needs to be cleaned and dumped, the liquid filter unit 4 needs to be removed and installed separately from the housing 1. Therefore, the simplest removal and installation method is the most easily accepted by users.

[0039] The locking unit includes a first locking mechanism 51 provided on the shell 1 and a second locking mechanism 52 provided on the liquid filter unit 4. The positions of the first locking mechanism 51 and the second locking mechanism 52 match each other, and the liquid filter unit 4 and the shell 1 are fixed through the locking unit.

[0040] The locking unit fixes the liquid filter unit 4 to the housing 1 so that the liquid filter unit 4 is not likely to fall off or fall out when the user is working, walking, or climbing a wall.

[0041] Through the cooperation between the first locking mechanism 51 and the second locking mechanism 52 in the locking unit, a tight connection between the liquid filter unit 4 and the housing 1 can be achieved, while also playing a role of stability and firmness.

[0042] like Figure 3 、 Figure 4 As shown, in one embodiment, the first locking mechanism 51 is disposed in the housing 1, or alternatively, the second locking mechanism 52 is disposed in the liquid filter unit 4. Alternatively, the first locking mechanism 51 can be disposed in the housing 1 and the second locking mechanism 52 can be disposed in the liquid filter unit 4 at the same time.

[0043] A step 111 is provided in the accommodating chamber 11, and the step 111 is provided at the upper edge of the accommodating chamber 11. The first locking mechanism 51 is provided on the step 111; the liquid filtration unit 4 is provided with a downward lower plane 41, and the second locking mechanism 52 is provided on the lower plane 41, and the lower plane 41 abuts against the step 111.

[0044] With this arrangement, when the liquid filter unit 4 is placed in the accommodating cavity 11 on the housing 1 , the liquid filter unit 4 can be supported on the step 111 , thus realizing a locking structure, making the structure of the present invention more stable.

[0045] In one embodiment, the shell 1 is provided with an inner side wall and / or an inner bottom wall in the accommodating cavity 11, and the first locking mechanism 51 is provided at the inner side wall and / or the inner bottom wall; the liquid filtration unit 4 is provided with a side wall and / or a bottom wall, and the second locking mechanism 52 is provided at the side wall and / or the bottom wall. When the liquid filtration unit 4 is placed in the accommodating cavity 11, the first locking mechanism 51 and the second locking mechanism 52 cooperate with each other.

[0046] In this embodiment, in addition to being fixed at the upper step 111, the side walls and / or the bottom wall can also be used to coordinate with each other to achieve fixation at more locations, thereby achieving a multi-dimensional, three-dimensional fixation method. This ensures that the liquid filter unit 4 is not likely to fall off when the pool cleaning device is in different cleaning modes or at different angles. This is especially true when the pool cleaning device is climbing a wall, forming a similar 90-degree angle to when the pool cleaning device is at the bottom of the pool. If the position is unstable, the liquid filter unit 4 is likely to fall off. Alternatively, when the pool cleaning device enters the water from the surface, it is well known that objects will be subject to the buoyancy resistance of the water as they sink. At this time, if the liquid filter unit 4 is only fixed at one point, it is likely to fall off due to the buoyancy, thereby affecting the normal cleaning of the pool cleaning device.

[0047] Therefore, when three-dimensional fixing is provided on the side wall and / or the bottom wall at the same time, the stability of the utility model is further enhanced, so that the cleaning effect is not affected by external factors.

[0048] In one embodiment, the first locking mechanism 51 is a magnetic suction component and the second locking mechanism 52 is a metal sheet that cooperates therewith; alternatively, the second locking mechanism 52 is a magnetic suction component and the first locking mechanism 51 is a metal sheet that cooperates therewith; or still further, the first locking mechanism 51 and the second locking mechanism 52 are magnetic suction components that attract each other.

[0049] These three implementations mainly focus on the possible cooperation between the magnetic attracting member and the metal or magnetic attracting member when achieving magnetic attraction. In this embodiment, in order to achieve a better attraction effect, magnetic attracting members are provided on both the first locking mechanism 51 and the second locking mechanism 52. When the magnetic attracting members between the first locking mechanism 51 and the second locking mechanism 52 are opposite in magnetic properties, the two magnetic poles are opposite in magnetic properties.

[0050] In one embodiment, the magnetic attraction member and / or the metal sheet are respectively arranged inside the first locking mechanism 51 and / or the second locking mechanism 52 and are integrated into one piece.

[0051] In the above embodiment, the magnetic element is formed together with the housing 1 during injection molding or compression molding, so that the magnetic element is always outside the housing 1, preventing the magnetic element from falling off due to equipment vibration during daily work or movement.

[0052] In one embodiment, a concave cavity is provided inside the first locking mechanism 51 and / or the second locking mechanism 52, and the magnetic attraction member and / or the metal sheet are respectively provided in the concave cavity of the first locking mechanism 51 and / or the second locking mechanism 52.

[0053] In the above embodiment, when the housing is injection molded, a small pit, groove, or cavity is first reserved, and then the magnetic element is placed in the reserved space. After placement, it can be covered with a lid or secured in the cavity with glue. All of these methods can achieve the same technical effect.

[0054] In one embodiment, the magnetic attraction member is a magnet, a magnet, or a flexible magnetic attraction member, all of which can achieve the same technical effects as the embodiments of the invention.

[0055] In one embodiment, the magnetic attraction member or metal sheet provided at the first locking mechanism 51 and the magnetic attraction member or metal provided at the second locking mechanism 52 at least partially overlap with each other in orthographic projection.

[0056] At least partial overlap is required to generate magnetic attraction between them, and the best effect is complete overlap.

[0057] In the swimming pool cleaning device provided in this embodiment, the liquid filter unit 4 is directly disposed on the accommodating chamber 11 in the housing 1, making it easy to remove and clean the liquid. At the same time, the interconnection between the first locking mechanism 51 and the second locking mechanism 52 also ensures a stable structure and a secure fit between the filter unit and the housing 1. When removing or placing the liquid, it is not affected by factors such as sand and particulate matter in the working environment.

[0058] During the specific implementation of this embodiment, magnetic parts in different directions, on different surfaces and at different angles can be simultaneously arranged at the step 111, side walls, lower bottom, etc. of the liquid filter unit 4, which are adsorbed on different surfaces of the shell 1 respectively, to achieve three-dimensional fixation and multi-dimensional mutual fixation and firm pulling, with better effect.

[0059] In one embodiment, a latch (not shown) is provided between the liquid filter unit 4 and the housing 1. The latch comprises a protrusion provided on the filter unit 4 and a groove or recess provided on the housing 1 that cooperates with the protrusion. Alternatively, the latch comprises a protrusion provided on the housing 1 and a groove or recess provided on the filter unit 4 that cooperates with the protrusion. When the two are brought into proximity or engaged, the protrusion and the groove or recess cooperate to form a snap-fit, thereby achieving a more stable structure.

[0060] Alternatively, the liquid filter unit 4 and the housing 1 are both provided with protrusions that cooperate with each other, and when the two protrusions are close to or cooperate with each other, they interlock with each other to make the structure more stable.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention shall be included within the scope of protection of the claims of the present invention.
