Description

Technical Field

[0001] This utility model relates to the technical field of water tank cleaning devices, and in particular to an automatic water tank cleaning device. Background Technology

[0002] Swimming pools are venues for people to swim. During the use of swimming pools, some solid waste is generated. The circulating water filtration system of swimming pools cannot effectively clean this waste. Therefore, swimming pools need to be cleaned regularly. Based on this, automatic pool cleaning equipment has emerged.

[0003] Automatic water tank cleaning equipment operates in water, requiring high waterproofing for its internal components. Components needing waterproofing are typically housed in sealed spaces, such as the control board and button module. There are two main design options for the control board and button module: one is to have separate control board and button compartments, requiring individual waterproofing treatment and wiring harness connection, increasing processing steps and costs; the other is to have a single control board compartment with the button module housed within it, sharing the same compartment. However, this design carries a higher risk of water ingress into the button module due to its frequent pressing. If water enters the control board compartment, it can easily cause control board malfunctions (such as short circuits), resulting in high repair costs and potentially rendering the entire machine unusable. Utility Model Content

[0004] Based on the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide an automatic water tank cleaning device that optimizes the structure of the control panel compartment and the button compartment, so that the control panel compartment and the button compartment share at least the first compartment wall. This reduces the number of waterproofing steps, reduces the length of the connecting wire harness between the button compartment and the control panel compartment, and lowers the assembly difficulty between the two compartments. If water enters the button module, the button compartment can effectively prevent water from seeping into the control panel compartment, thereby improving the waterproof reliability and safety of the device.

[0005] Therefore, the present invention provides the following technical solution.

[0006] This utility model provides an automatic water tank cleaning device, comprising:

[0007] case;

[0008] The control panel compartment is located inside the housing;

[0009] At least a portion of the key compartment is disposed within the housing, the control board compartment and the key compartment share at least a first compartment wall, the control board compartment and the key compartment are sealed together, and the components within the key compartment are electrically connected to the control board compartment.

[0010] Optionally, the button compartment is connected to a wiring harness, and the first compartment wall is provided with a through hole. The wiring harness connector passes through the through hole to electrically connect the components inside the button compartment to the control board compartment.

[0011] Optionally, the button compartment is located above the control panel compartment, and the first compartment wall is the bottom wall of the button compartment and the upper wall of the control panel compartment.

[0012] Optionally, the control panel compartment is equipped with a circuit board, a battery pack, and a motor for the drive device.

[0013] Optionally, the control panel can contain gas.

[0014] Optionally, a first sealing element is provided between the button compartment and the first compartment wall.

[0015] Optionally, the first compartment wall is provided with a slot, and the button compartment includes a base, on which a protruding structure that cooperates with the slot is provided.

[0016] Optionally, the first seal is disposed between the slot and the protrusion.

[0017] Optionally, the base is connected to the first silo wall by fasteners.

[0018] Optionally, the wire harness connector is sealed to the wall of the through hole by a second seal.

[0019] This utility model has the following technical effects:

[0020] This utility model provides an automatic water tank cleaning device. It optimizes the structure of the control panel compartment and button compartment by setting up two independent control panel compartments and button compartments, which are sealed together. Furthermore, the control panel compartment and button compartment share at least one common wall. Compared to existing technologies that require separate waterproofing treatments for two independent compartments, this solution reduces the number of waterproofing steps, shortens the wiring harness length between the button compartment and the control panel compartment, eliminates the need for wiring and other assembly processes, and simplifies the assembly of the control panel compartment and button compartment, thereby reducing processing costs and improving processing efficiency. Compared to solutions that place the button module inside the control panel compartment, this solution features a sealed and relatively independent control panel compartment and button compartment. If water enters the button module, the button compartment effectively prevents water from seeping into the control panel compartment, improving the waterproof reliability, safety, and service life of the equipment.

[0041] In this utility model, "upper" and "lower" refer to... Figure 1 The markings in the text shall prevail.

[0042] The following is based on Figures 1 to 5 This utility model describes the automatic water tank cleaning device in detail.

[0043] In this embodiment, such as Figure 5 As shown, the automatic pool cleaning equipment includes a housing 7, a power component (such as a water pump), a walking mechanism 8 (such as tracks), cleaning components 9 (such as a roller brush), an airbag, and a filter (such as a filter basket). During the cleaning process, the water pump draws water from the pool, which is then filtered before being discharged back into the pool. Debris is trapped in the filter, thus achieving the cleaning purpose. The airbag enables the machine to float and sink in the pool and also assists the machine in overcoming obstacles for cleaning steps and pool walls. The arrangement of the various components inside the machine can be configured according to actual needs, and this embodiment does not impose specific limitations.

[0044] In this application, the water tank includes, but is not limited to, swimming pools, water storage tanks, spa pools, water storage tanks, or water storage troughs. The automatic water tank cleaning device can be a device such as an automatic cleaning machine or a water tank cleaning robot, capable of cleaning the water tank. The automatic water tank cleaning device generally moves automatically according to received instructions or a pre-compiled program. For example, the automatic water tank cleaning device moves along the pool wall using its walking mechanism.

[0045] like Figures 1 to 5 As shown, the automatic water tank cleaning device includes a control panel compartment 1 housed within a housing 7 and a button compartment 2, at least partially housed within the housing 7. A portion of the button compartment 2 is located outside the housing 7; for example, the button module 22 on the button compartment 2 is at least partially located outside the housing 7 to facilitate user operation. The control panel compartment 1 and the button compartment 2 share at least a first compartment wall 11. The control panel compartment 1 has a control chamber 12, and the button compartment 2 has a button chamber 23. The first compartment wall 11 can form both one side of the control chamber 12 and one side of the button chamber 23. Alternatively, the control panel compartment 1 and the button compartment 2 can share other compartment walls. For example, the control panel compartment can be L-shaped and partially surround the button compartment, allowing them to share two compartment walls. Preferably, to simplify the compartment structure and facilitate overall miniaturization, the control panel compartment 1 and the button compartment 2 only share the first compartment wall 11. The control panel compartment 1 and the button compartment 2 are sealed together to prevent water leakage. The components (such as buttons) in the button compartment 2 are electrically connected to the control board compartment 1. The circuit board in the control board compartment 1 is used to receive signals from the button module 22 on the button compartment 2, and then issue execution commands to the corresponding execution components according to the instructions of the signals.

[0046] The above technical solution optimizes the structure of the control board compartment 1 and the button compartment 2 by setting up two independent control board compartments and button compartments, with a sealed connection between them. Furthermore, the control board compartment 1 and the button compartment 2 share at least the first compartment wall 11. Compared to the existing technology that requires separate waterproofing treatment for each of the two independent compartments, this solution reduces the number of waterproofing steps. Additionally, the wiring harness connected to the button compartment 2 can directly pass through the first compartment wall 11 to achieve electrical connection with the components inside the control board compartment 1, reducing the number of connections between the button compartment 2 and the control board compartment. The wiring harness arrangement process between the control panel compartment 1 and the button compartment 2 reduces the assembly difficulty between them, thereby reducing processing costs and improving processing efficiency. In addition, compared with the existing technology that places the button module in the control panel compartment, the control panel compartment 1 and the button compartment 2 are sealed and relatively independent in this solution. The control compartment 12 and the button compartment 23 do not interfere with each other. If water enters the button module 22, the button compartment 2 can effectively prevent water from seeping from the button module 22 into the control panel compartment 1, thereby improving the waterproof reliability and safety of the equipment.

[0047] In one embodiment, a wiring harness (not shown) is connected to the button compartment 2. This harness is used to electrically connect the components inside the button compartment 2 to components such as the circuit board and battery pack inside the control compartment 1. Figure 1 and Figure 2 As shown, the first compartment wall 11 has a through hole 111. The wire harness connector 3 passes through the through hole 111 to electrically connect the components inside the button compartment 2 to the control board compartment 1. The wire harness connector 3 can be an SR wire harness connector, conforming to the SR series standard and having waterproof performance. Specifically, the wire harness connector 3 is installed in the through hole 111 of the first compartment wall 11. One end of the wire harness connector 3 is opposite to or extends into the control compartment 12, and the other end of the wire harness connector 3 is opposite to or extends into the button compartment 23. The wire harness electrically connects the components inside the button compartment 2 to the control board compartment 1 through the wire harness connector 3. The wire harness connector 3 has a waterproof sealing function, ensuring a sealed state between the control board compartment 1 and the button compartment 2. Since the button compartment 2 and the control board compartment 1 share a first compartment wall 11, and are very close to each other, the external wire harness of the button compartment 2 can directly pass through the first compartment wall 11 to achieve electrical connection with the internal components of the control board compartment 1, eliminating the need for wiring and other assembly processes, thus reducing equipment costs and assembly steps. Furthermore, if the button module malfunctions, the button compartment 2 can be inspected and repaired directly by plugging and unplugging the wire harness connector 3.

[0048] In one implementation, such as Figure 1As shown, the button compartment 2 is located above the control panel compartment 1. The first compartment wall 11 is the bottom wall of the button compartment 2 and the top wall of the control panel compartment 1. It should be explained that in this text, "first compartment wall" refers to the overall structure of one side wall of the compartment; the first compartment wall is a three-dimensional structure with a certain wall thickness, not a single wall surface. In this design, the upper surface of the first compartment wall 11 forms the bottom wall of the button compartment 23, and the lower surface of the second compartment wall 11 forms the top wall of the control panel compartment 12. The button compartment 2 and the control panel compartment 1 are separated by the first compartment wall 11. The surface of the first compartment wall 11 can be planar, such as... Figure 2 As shown, the first compartment wall 11 can also be a wall surface with an uneven structure. The control compartment 1 is generally larger than the button compartment 2, and the first compartment wall 11 can be part of the side wall of the control panel compartment 1. The button compartment 2 is positioned higher than the control panel compartment 1, making it easier for users to quickly find and operate the button module 22. The operation is intuitive and convenient. Furthermore, when the automatic water cleaning equipment is used for water surface cleaning, it can reduce the contact between the button module 22 and water, reducing the risk of water leakage from the button module 22.

[0049] In one embodiment, the control compartment 1 is equipped with a circuit board, a battery pack, and a motor for the drive device. The circuit board is used to control the operation of the equipment, the battery pack is used to supply power to the equipment, and the motor is used to provide power to the corresponding components (such as a water pump).

[0050] In one embodiment, the control chamber 1 can contain gas, thus also serving as a gas storage chamber. The control chamber 1 can contain high-pressure gas or atmospheric-pressure gas. Furthermore, since the control chamber 1 and the button chamber 2 are separated by a first chamber wall 11, pressure changes within the control chamber 1 will not affect the performance of the button module 22, ensuring the stability of the button module 22's performance.

[0051] In one implementation, such as Figure 1 and Figure 2 As shown, since the water loss from the control panel compartment 1 is higher than that from the button compartment 2, the first compartment wall 11 is formed on the control panel compartment 1, that is, the first compartment wall 11 is integrally formed with the other side walls of the control panel compartment 1. This helps to improve the sealing performance of the control panel compartment 1 and reduce the risk of water leakage. Furthermore, a first sealing element 4 is provided between the button compartment 2 and the first compartment wall 11 to ensure a sealed connection between the button compartment 2 and the control panel compartment 1, thus ensuring the internal sealing performance of the button compartment 2. Of course, the first compartment wall 11 can also be integrally formed on the button compartment 2.

[0052] Furthermore, such as Figures 1 to 3As shown, the first chamber wall 11 is provided with a slot 112, and the button chamber 2 includes a base 21. The base 21 is provided with a protruding structure 211 that cooperates with the slot 112. The button chamber 2 and the control panel chamber 1 are assembled together by connecting the base 21 and the first chamber wall 11. Specifically, when assembling the button chamber 2 and the control panel chamber 1, the protruding structure 211 is engaged in the slot 112. In this way, the engagement of the protruding structure 211 and the slot 112 can form a maze structure, increasing the complexity of the water inflow path and improving the sealing security between the button chamber 2 and the control panel chamber 1. That is, it can increase the difficulty for water to enter the button chamber 23, thus playing a waterproof role.

[0053] Furthermore, such as Figure 1 As shown, the first seal 4 is disposed between the slot 112 and the protrusion 211 to ensure the sealing of the assembly of the slot 112 and the protrusion 211.

[0054] Furthermore, such as Figure 2 and Figure 3 As shown, the slot 112 is an annular slot, the raised structure 211 is an annular raised structure, and the first sealing element 4 is an O-ring. In this way, on the one hand, the stability of the engagement between the slot 112 and the raised structure 211 can be improved, and on the other hand, the engagement point of the slot 112 and the raised structure 211 is set around the button chamber 23, which helps to increase the difficulty of water flowing into the button chamber 23 and improve the waterproof performance.

[0055] In one implementation, such as Figure 1 As shown, the base 21 is connected to the first compartment wall 11 by fasteners 5. Specifically, when assembling the control panel compartment 1 and the button compartment 2, the slot 112 is first engaged with the protruding structure 211 to play a pre-assembly role. Then, the base 21 is connected to the first compartment wall 11 by fasteners 5 to play a fixing role, ensuring the firmness of the assembly of the button compartment 2 and the control panel compartment 1, and making the assembly convenient.

[0056] Furthermore, such as Figure 1 As shown, the fastener 5 is located on the side of the protrusion 211 away from the button chamber 23. In this way, the mounting point of the fastener 5 is separated from the button chamber 23 by the engagement between the protrusion 211 and the slot 112. If water enters the mounting point of the fastener 5, the water will be blocked on the outside of the engagement between the slot 112 and the protrusion 211, thus preventing water from entering the button chamber 23 due to water entering the mounting point of the fastener 5.

[0057] In one embodiment, the wire harness connector 3 is sealed to the wall of the through hole 111 by a second seal 6, so that the control panel compartment 1 and the button compartment 2 can be completely isolated as much as possible, ensuring bidirectional independent airtight and watertight isolation between the control compartment 12 and the button compartment 23, eliminating air pressure transmission and fluid permeation paths between the two compartments. Furthermore, to improve sealing, the second seal 6 is an O-ring, and there are two or more second seals 6, all of which are spaced apart along the axial direction of the wire harness connector 3 and fitted onto the wire harness connector 3.

[0058] Furthermore, to further improve the waterproof performance of the wire harness connector 3, the connection between the wire harness connector 3 and the through hole 111 is coated with waterproof adhesive to form double waterproof protection.

[0059] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
