Description

Technical Field

[0001] The present invention relates to the technical field of swimming pool equipment, and in particular to a rechargeable swimming pool equipment and a charging system. Background Art

[0002] Swimming pools are places where people swim and need to be cleaned regularly. Now people often use pool cleaning robots to clean swimming pools. The emergence of pool cleaning robots has liberated labor and improved the quality of life.

[0003] At present, most pool cleaning robots on the market use plug-in charging, which is not convenient for users to operate. Based on this, a few pool cleaning robots use magnetic charging solutions to overcome this problem. Specifically, the body and charger of the pool cleaning robot are equipped with magnets that can attract each other. Users only need to roughly align the charging end of the charger with the charging end of the body, and then let go to automatically align and charge. There is no need to plug and unplug operations, which brings great convenience to users. However, this magnetic charging solution also has problems: the charging port of the body is magnetic, which will cause ferromagnetic materials such as iron filings in the swimming pool to be adsorbed on or near the charging port when the pool cleaning robot is working in the water. Not only is it difficult to clean, but it will also cause poor charging contact due to excessive impurities. If the charging port of the machine itself is not magnetic, the alignment accuracy between the machine and the charging end of the charger is low. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rechargeable swimming pool device which can be quickly charged and will not absorb ferromagnetic impurities, and a charging system having the rechargeable swimming pool device.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a rechargeable swimming pool equipment, including a main body and a controllable magnetic part arranged on the main body, the main body is provided with a charging interface, the controllable magnetic part is arranged close to the charging interface, and the controllable magnetic part is configured to be able to switch between magnetic and non-magnetic states.

[0006] In order to solve the above technical problems, the present invention also adopts the following technical solution: a charging system, including the above-mentioned rechargeable swimming pool equipment.

[0007] The beneficial effects of the present invention are as follows: the structure of the rechargeable swimming pool equipment is novel, and a controllable magnetic part that can switch between magnetic and non-magnetic states is provided near the charging interface of the main body. The controllable magnetic part is non-magnetic when the rechargeable swimming pool equipment is working, ensuring that the rechargeable swimming pool equipment will not absorb any iron filings and other ferromagnetic impurities when working under water / on the surface of the water. The controllable magnetic part is magnetic when the rechargeable swimming pool equipment is charging, so that the charging interface of the main body can be accurately aligned with the external interface of the external charger, so that the user can quickly charge the rechargeable swimming pool equipment. Compared with the solution of setting a permanent magnet on the rechargeable swimming pool equipment, the controllable magnetic part will not absorb ferromagnetic impurities such as iron filings when the rechargeable swimming pool equipment is working, and the user does not need to frequently clean the rechargeable swimming pool equipment, which is conducive to enhancing the user experience, and the charging interface will not have a problem of poor contact with the external interface due to the adsorption of ferromagnetic impurities, ensuring that the rechargeable swimming pool equipment can be stably charged.

[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0017] Please refer to Figure 1 A rechargeable swimming pool device includes a main body 1 and a controllable magnetic part 2 arranged on the main body 1, the main body 1 is provided with a charging interface 3, the controllable magnetic part 2 is arranged close to the charging interface 3, and the controllable magnetic part 2 is configured to be able to switch between magnetic and non-magnetic states.

[0018] From the above description, it can be seen that the beneficial effects of the present invention are: the present rechargeable swimming pool equipment has a novel structure and can be quickly connected with the external interface 63 of the external charger 6. Compared with the solution of setting a permanent magnet on the rechargeable swimming pool equipment, the controllable magnetic part 2 will not absorb ferromagnetic impurities such as iron filings when the rechargeable swimming pool equipment is working. The user does not need to frequently clean the rechargeable swimming pool equipment, which is conducive to enhancing the user experience. The charging interface 3 will not have a poor contact with the external interface 63 due to the adsorption of ferromagnetic impurities, thereby ensuring that the rechargeable swimming pool equipment can be charged stably.

[0019] Furthermore, the controllable magnetic component 2 is at least one of an electro-permanent magnet, a common electromagnet, a holding electromagnet and a power-off electromagnet.

[0020] From the above description, it can be seen that there are many types of controllable electromagnet modules, which can be selected according to actual conditions, thus enriching the diversity of rechargeable swimming pool equipment.

[0021] Furthermore, the main body 1 is provided with a controller 4 electrically connected to the controllable magnetic component 2 , and the controller 4 is used to control the controllable magnetic component 2 to switch between a magnetic state and a non-magnetic state.

[0022] From the above description, it can be seen that the controller 4 is electrically connected to the controllable magnetic component 2, so that the controllable magnetic component 2 can switch between the magnetic and non-magnetic states under the instruction of the controller 4; the existence of the controller 4 can realize automatic control of the controllable magnetic component 2 without human intervention.

[0023] Furthermore, the controller 4 is connected to the charging interface 3. When the controller 4 detects that the charging interface 3 is connected to the external interface 63, the controller 4 controls the controllable magnetic component 2 to switch to a magnetic state; when the controller 4 detects that the charging interface 3 is disconnected from the external interface 63, the controller 4 controls the controllable magnetic component 2 to switch to a non-magnetic state.

[0024] From the above description, it can be seen that when the rechargeable swimming pool equipment is charging, the controllable magnetic part 2 can show magnetism, so that the charging interface 3 is connected to the external interface 63 through magnetism. When the rechargeable swimming pool equipment is not charging, the controllable magnetic part 2 does not show magnetism, thereby ensuring that the controllable magnetic part 2 will not absorb ferromagnetic debris in the swimming pool, which is beneficial to reduce the workload of cleaning and maintenance of the rechargeable swimming pool equipment itself.

[0025] Furthermore, the charging interface 3 is a terminal interface or a wireless interface.

[0026] From the above description, it can be seen that when the rechargeable swimming pool equipment is charged by wireless charging, the controllable magnetic part 2 can make the wireless interface more convenient and accurate to dock with the external interface 63. When the rechargeable swimming pool equipment is charged by contact charging, the terminal interface has good conductivity and the docking operation is smoother.

[0027] Furthermore, the controllable magnetic component 2 does not show magnetism when powered on, but shows magnetism when powered off.

[0028] It can be seen from the above description that when the rechargeable swimming pool equipment is being charged, the controllable magnetic component 2 can be powered off.

[0029] Furthermore, the controllable magnetic component 2 shows magnetism when powered on, and does not show magnetism when powered off.

[0030] From the above description, it can be seen that when the rechargeable swimming pool equipment is not being charged, it does not consume electrical energy to maintain the "non-magnetic" state.

[0031] Furthermore, the rechargeable swimming pool equipment is a swimming pool cleaning robot.

[0032] Furthermore, the main body 1 includes a shell 11, a water pump and a filter. The shell 11 is provided with a water inlet and a water outlet. The shell 11 is provided with a water flow channel connecting the water inlet and the water outlet. The water pump and the filter are both arranged in the water flow channel. The controllable magnetic part 2 is arranged on the shell 11.

[0033] It can be seen from the above description that the swimming pool cleaning robot can filter the water in the swimming pool, thereby cleaning the water in the swimming pool.

[0034] Furthermore, the main body 1 also includes a battery, which is installed on the shell 11 and is directly or indirectly electrically connected to the charging port 3 .

[0035] It can be seen from the above description that the connection method between the charging interface 3 and the battery can be set according to actual conditions.

[0036] A charging system comprising the above-mentioned rechargeable swimming pool equipment.

[0037] From the above description, it can be seen that the user operation is easy and the user experience is good.

[0038] Embodiment 1

[0039] Please refer to Figure 1 , Embodiment 1 of the present invention is: a charging system, the charging system includes an external charger 6 and a rechargeable swimming pool device.

[0040] The rechargeable swimming pool equipment includes but is not limited to a swimming pool cleaning robot. The rechargeable swimming pool equipment includes a main body 1 and a controllable magnetic part 2 arranged on the main body 1. The main body 1 is provided with a charging interface 3. The controllable magnetic part 2 is arranged near the charging interface 3. The controllable magnetic part 2 is configured to be able to switch between two states: magnetic and non-magnetic. The controllable magnetic part 2 is at least one of an electro-permanent magnet, a common electromagnet, a retaining electromagnet and a de-energized electromagnet. The main body 1 is provided with a controller 4 electrically connected to the controllable magnetic part 2, and the controller 4 is used to control the controllable magnetic part 2 to switch between a magnetic state and a non-magnetic state. The external charger 6 has a magnetic attraction structure 61, and the magnetic attraction structure 61 is provided with a permanent magnet 62 for magnetically matching with the controllable magnetic part 2 and an external interface 63 for matching with the charging interface 3.

[0041] This embodiment is described by taking a swimming pool cleaning robot as an example (i.e., the rechargeable swimming pool equipment of this embodiment is a swimming pool cleaning robot). The main body 1 includes a shell 11, a water pump, a battery, and a filter. The shell 11 is provided with a water inlet and a water outlet. The shell 11 is provided with a water flow channel connecting the water inlet and the water outlet. The water pump and the filter are both arranged in the water flow channel. The controllable magnetic part 2 is arranged on the shell 11. The battery is installed on the shell 11. The battery is directly or indirectly electrically connected to the charging interface 3.

[0042] Specifically, a sealed chamber 12 is provided in the shell 11, and the battery and the controller 4 are respectively arranged in the sealed chamber 12. The battery is indirectly electrically connected to the charging interface 3 through the controller 4. The controller 4 includes a main control board, and the main control board is electrically connected to the charging interface 3 through a first connecting line 51 and electrically connected to the controllable magnetic part 2 through a second connecting line 52.

[0043] Optionally, a charging structure 13 is provided on the shell 11 , the charging interface 3 and the controllable magnetic component 2 are both provided on the charging structure 13 , and the charging structure 13 is sealed and connected to the shell 11 .

[0044] When the controller 4 detects that the charging interface 3 is connected to the external interface 63, the controllable magnetic component 2 is controlled to switch to a magnetic state; when the controller 4 detects that the charging interface 3 is disconnected from the external interface 63, the controllable magnetic component 2 is controlled to switch to a non-magnetic state. Optionally, the controllable magnetic component 2 does not display magnetism when powered on, and displays magnetism when powered off. In detail, when the rechargeable swimming pool equipment is turned on and enters the charging current detection state, if no charging current is detected, the main control board will energize the controllable magnetic part 2. At this time, the controllable magnetic part 2 is not magnetic (the controllable magnetic part 2 selected at this time is an electro-permanent magnet), and the rechargeable swimming pool equipment can enter the water normally to work. The controllable magnetic part 2 is always energized during operation. At this time, since the controllable magnetic part 2 is not magnetic, the controllable magnetic part 2 will not absorb ferromagnetic impurities. When the rechargeable swimming pool equipment is taken ashore, it will automatically shut down through detection (normal mode, the rechargeable swimming pool equipment cannot be charged when it is turned on, and an alarm will be issued). At this time, after the rechargeable swimming pool equipment is turned off, the main control board will not energize the controllable magnetic part 2, and the controllable magnetic part 2 will immediately show magnetism, and the charging interface 3 can be normally aligned with the external interface 63 of the external charger 6 for charging. Since the controllable magnetic part 2 does not absorb ferromagnetic impurities such as iron filings in the water, the rechargeable swimming pool equipment can be stably charged using the charging interface 3.

[0045] Of course, the controllable magnetic part 2 shows magnetism when it is powered on, and does not show magnetism when it is powered off. This setting is also possible. Specifically, when the rechargeable swimming pool equipment is turned on and enters the charging current detection state, if no charging current is detected, the main control board does not power on the controllable magnetic part 2. At this time, the controllable magnetic part 2 is not magnetic (the controllable magnetic part 2 selected at this time is an ordinary electromagnet, etc.), and the rechargeable swimming pool equipment can enter the water normally to work. The controllable magnetic part 2 is not powered during work. At this time, since the controllable magnetic part 2 is not magnetic, the controllable magnetic part 2 will not absorb ferromagnetic impurities. When the rechargeable swimming pool equipment is taken ashore, it automatically shuts down through detection. At this time, after the rechargeable swimming pool equipment is turned off, the main control board continues to power on the controllable magnetic part 2 within a preset time period. The controllable magnetic part 2 shows magnetism, and the charging interface 3 can be normally aligned with the external interface 63 of the external charger 6 for charging. Since the controllable magnetic part 2 does not absorb ferromagnetic impurities such as iron filings in the water, the rechargeable swimming pool equipment can be stably charged using the charging interface 3. It should be noted that during the charging process of the rechargeable swimming pool equipment, the control methods do not necessarily have to be the two above-mentioned control methods. Other control methods can also be used. For example, the rechargeable swimming pool equipment does not automatically shut down after landing, and the rechargeable swimming pool equipment can be charged while it is turned on.

[0046] In some embodiments, the charging interface 3 may be a wireless interface. The use of a wireless interface enables contactless charging of the rechargeable swimming pool equipment, which is beneficial to improving the sealing and charging safety of the rechargeable swimming pool equipment; specifically, the wireless interface is a wireless charging receiving module. However, in order to allow the rechargeable swimming pool equipment to be charged stably and efficiently, in this embodiment, the charging interface 3 is a terminal interface, which may be an elastic conductive part with a contact area, such as a spring, an elastic probe, etc.; or a hard conductive part with a contact area, such as a metal sheet, etc.

[0047] In summary, the rechargeable swimming pool equipment and charging system provided by the present invention have novel structures. The rechargeable swimming pool equipment will not absorb any iron filings and other ferromagnetic impurities when working under water or on the surface of water. When charging, it can achieve precise alignment with the external interface of the external charger, so that users can quickly charge the rechargeable swimming pool equipment. Later, users do not need to frequently clean the rechargeable swimming pool equipment, which is conducive to enhancing user experience.
