Description

Technical Field

[0001] This utility model relates to the field of intelligent cleaning equipment technology, specifically to a swimming pool robot, and more particularly to a swimming pool robot with a novel battery compartment. Background Technology

[0002] In the field of pool cleaning, pool robots have gradually gained popularity among users in recent years as a professional cleaning device, and their importance is becoming increasingly apparent. Especially in private and public pools, these robots can save labor costs and perform repetitive daily tasks. Therefore, they have gradually become the preferred robot for pool cleaning.

[0003] However, existing pool robots require them to be fully and continuously submerged underwater for extended periods. During operation, these underwater robots are susceptible to vibrations, high temperatures, and other factors, which can lead to seal failures.

[0004] However, the sealed structure of typical pool robots has the following drawbacks and shortcomings:

[0005] 1. The battery compartment cannot be tested during the production process and use; we can only be responsible for the sample and cannot predict the risks of the product.

[0006] 2. Traditional sealing structures require secondary or multiple applications of adhesive, resulting in excessive weight of the battery compartment, high manufacturing costs, and complex manufacturing processes.

[0007] 3. The process control for internal potting can only be applied to test samples, not to every single product, making the manufacturing process complex.

[0008] Therefore, how to make the sealing structure of pool robots easy to manufacture, have a good sealing effect, and be able to predict product risks after sealing are technical problems that the industry urgently needs to solve. Utility Model Content

[0009] The present invention aims to overcome the shortcomings of the prior art and provide a swimming pool robot to solve the problems of high manufacturing cost, complex manufacturing process and unpredictable product risks of existing swimming pool robots.

[0010] The technical solution adopted by this utility model is to provide a battery compartment, which includes:

[0011] The compartment has an internal cavity for accommodating the battery, and one side of the compartment has an opening. The opening facilitates the placement, installation, and securing of the battery within the compartment, as well as the connection of the power supply components, such as the control circuit and wiring connected to the battery.

[0012] The chamber includes an outer shell and an inner shell, with a hollow cavity formed between the outer shell and the inner shell.

[0013] In this embodiment, the outer shell and inner shell are preferably made of rigid materials, such as metal shells or hard plastic shells.

[0014] After the battery is fixed in the inner cavity, a sealant is fixed at the opening. The sealant seals the battery in the inner cavity and simultaneously seals the outer shell and the inner shell, so that a hollow cavity is formed between the outer shell and the inner shell.

[0015] The inner cavity is also equipped with power leads, which extend outward through the outer shell and inner shell or sealant. These power leads include power leads for control circuits, battery-powered circuits, and sensor circuits.

[0016] Furthermore, a temperature sensor is installed inside the shell cavity. The temperature sensor can be fixed inside the outer shell or the inner shell, with the same effect.

[0017] Furthermore, a pressure sensor is installed inside the shell cavity. The pressure sensor can be fixed inside the outer shell or the inner shell, with the same effect.

[0018] Temperature and pressure sensors can be used to detect changes in temperature and pressure inside the battery compartment, thereby determining the battery compartment's condition during use and predicting potential risks within the battery compartment.

[0019] Furthermore, the pressure inside the shell cavity is 0.8-1.2 Pa. The shell cavity is at natural atmospheric pressure, so there is no need for a special vacuum setting.

[0020] Furthermore, the outer shell and / or inner shell are provided with protrusions at the shell cavity. The function of the protrusions is that after the sealant is fixed, pulling on the protrusions provides a stabilizing effect without adding any fixing parts. When the temperature or pressure of the shell cavity changes, causing deformation between the outer shell and the inner shell, the sealant can easily detach from the outer shell or inner shell.

[0021] Furthermore, the inner housing is also provided with a protrusion in the inner cavity. The protrusion provided in the inner housing is similar in principle to the protrusion provided on the outer housing.

[0022] Furthermore, the outer shell and inner shell have roughened surfaces at the sealing adhesive application points. These roughened surfaces improve the adhesion of the sealant during bonding.

[0023] Furthermore, the rough surface can be provided with several small granular protrusions or depressions, or it can be made into a frosted surface.

[0024] Furthermore, the cross-section of the raised part is L-shaped or T-shaped, and can also be "丰"-shaped or "干"-shaped. Setting the raised part with a special shape can strengthen the connection between the sealant and the outer shell and the inner shell, so that it can be detached when heated or the pressure changes. At the same time, it also prevents the machine from falling off due to vibration during operation.

[0025] A pool robot includes a pool robot body. A filtering device is arranged inside the pool robot body. An inlet is arranged at the bottom of the pool robot body and is communicated with the filtering device. An outlet is arranged on the side or / and the upper part of the pool robot body.

[0026] A battery compartment is arranged inside the pool robot body, and the battery compartment is the battery compartment in the present utility model.

[0027] Furthermore, the battery compartment is detachably installed inside the pool robot body.

[0028] The beneficial effects of the present utility model are as follows:

[0029] The pool robot provided by the present utility model has a double-layer shell with a shell cavity. The temperature and pressure in the shell cavity are detected in real time, and the working state of the product can be predicted and judged, achieving the effect of real-time monitoring; setting the shell cavity also saves the complex process of applying glue to the entire traditional cavity, and at the same time saves costs and reduces the overall weight; when detecting the product, only the temperature and pressure data need to be referred to, avoiding the complex and cumbersome processes such as the traditional need to conduct pressure tests on each battery.

[0036] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0037] Example 1

[0038] like Figure 1-5 As shown, this embodiment provides a battery compartment, which includes:

[0039] The compartment has an inner cavity 13 for accommodating the battery, and one side of the compartment has an opening. The opening facilitates the placement, installation, and fixing of the battery inside the compartment, as well as the connection of the power supply components such as the control circuit and wires connected to the battery.

[0040] The chamber includes an outer shell 11 and an inner shell 12, with a hollow cavity 14 formed between the outer shell 11 and the inner shell 12.

[0041] After the battery is fixed in the inner cavity 13, a sealant 3 is fixed at the opening. The sealant 3 seals the battery in the inner cavity 13 and simultaneously seals the outer shell 11 and the inner shell 12, so that a hollow cavity 14 is formed between the outer shell 11 and the inner shell 12.

[0042] The sealant 3 is typically made from a base of dry or non-drying viscous substances such as asphalt, natural or synthetic resins, or natural or synthetic rubber, combined with inert fillers such as talc, kaolin, carbon black, titanium dioxide, and asbestos, and further supplemented with plasticizers, solvents, curing agents, and accelerators. In this embodiment, the sealant 3 used is preferably a high-temperature sealant. To allow clear visualization of changes in the battery inside the battery compartment or the state of circuit contacts, the sealant 3 can also be a transparent or semi-transparent sealant.

[0043] A power lead 4 is also provided inside the inner cavity 13. The power lead 4 extends outward from the inner cavity 13 through the outer shell 11 and the inner shell 12 or the sealant 3. The power lead 4 includes power leads for control circuits, power leads for battery power, power leads for sensors, etc.

[0044] In one embodiment, a temperature sensor 5 is disposed within the cavity 14. The temperature sensor 5, located within the cavity 14, can be fixed either inside the outer shell 11 or on the inner shell 12, achieving the same effect. The temperature sensor 5 can transmit the temperature within the cavity 14 to the pool robot in real time, thereby detecting temperature changes and determining whether the battery fixed within the chamber is in normal working condition.

[0045] A baseline temperature value can be assigned to the pool robot. When the temperature exceeds the baseline value, it is determined that the battery compartment temperature is too high. At this time, the pool robot will stop working and can also remind the user to check the machine status.

[0046] In one embodiment, a pressure sensor 6 is disposed within the cavity 14. The pressure sensor 6, disposed within the cavity 14, can be fixed either within the outer shell 11 or on the inner shell 12, with the same effect.

[0047] The pressure sensor 6 can transmit the pressure signal inside the cavity 14 to the pool robot in real time, thereby knowing the pressure change inside the cavity 14 in real time, and thus determining whether the battery fixed in the chamber is in normal working condition.

[0048] Because the cavity 14 is in a sealed state, when the outer shell 11 or the inner shell 12 deforms, the pressure inside the cavity 14 will change due to the deformation. Therefore, a reference pressure value (such as 0.8-1.2 Pa) can be first assigned to the pool robot. When the reference pressure value is exceeded, it is determined that the battery compartment pressure is too high. At this time, the pool robot will stop working, and the user can also be reminded to check the machine status.

[0049] In one embodiment, the pressure inside the cavity 14 is 0.8-1.2 Pa. The cavity 14 is at natural atmospheric pressure, and no special vacuum setting is required.

[0050] In one embodiment, the outer shell 11 and / or the inner shell 12 are further provided with a protrusion 15 at the cavity 14. The protrusion 15 serves to stabilize the sealant 3 after it is fixed, without adding any additional fixing components. When the temperature or pressure of the cavity 14 changes, causing deformation between the outer shell 11 and the inner shell 12, the sealant 3 may easily detach from the outer shell 11 or the inner shell 12.

[0051] In one embodiment, the inner housing 12 is further provided with a protrusion 15 at the inner cavity 13. The protrusion 15 provided at the inner housing 12 is similar to the protrusion 15 provided on the outer housing 11.

[0052] like Figure 3As shown, in this embodiment, the preferred solution is that both the outer housing 11 and the inner housing 12 are provided with protruding members 15, and the protruding direction of the protruding members 15 is horizontally protruding into the housing cavity 14 respectively. The simultaneous setting of the horizontal protruding members 15 makes the structure more stable and the sealant 3 not easily fall off.

[0053] When the protruding member 15 is integrally formed with the inner housing 12 or the outer housing 11, the effect is better.

[0054] In one embodiment, the outer housing 11 and the inner housing 12 are provided with a rough surface (not shown in the figure) at the fixed sealant 3. The rough surface is conducive to better enhancing the adhesion force when the sealant 3 is adhered.

[0055] In one embodiment, several small granular protrusions or depressions can be provided on the rough surface, or it can be set as a matte surface.

[0056] Similarly, a rough surface similar to the above can also be provided on the protruding member 15, and its effect is the same as that of the rough surfaces provided on the outer housing 11 and the inner housing 12.

[0057] In one embodiment, the cross-section of the protruding member 15 is in an "L" shape or a "T" shape, and can also be in a "Feng" shape or a "Gan" shape. The setting of the special-shaped protruding member 15 can strengthen the connection between the sealant 3 and the outer housing 11 and the inner housing 12, so that it does not detach when heated or the pressure changes. At the same time, it also prevents the machine from falling off due to vibration during operation.

[0058] As Figure 4 shown, in this embodiment, the protruding member 15 has the simplest cross-section in an "L" shape, which can both achieve the effect of the present utility model, while being the most material-saving in structure and the simplest in solution. The "L" shape has both horizontal and vertical pulling forces, making the structure more stable.

[0059] As Figure 5 shown, the cross-section of the protruding member 15 is in a "T" shape, and it can all achieve the technical effects of the present utility model.

[0060] In this embodiment, when the battery compartment is applied to a pool robot (not shown in the figure), it includes a pool robot body. A filtering device is provided inside the pool robot body, a water inlet communicating with the filtering device is provided at the bottom of the pool robot body, and a water outlet is provided at the side or / and the upper part of the pool robot body. [[ID=二十九]]

[0061] A battery compartment is provided inside the pool robot body, and the battery compartment is the battery compartment in the present utility model.

[0062] In one embodiment, the battery compartment is detachably installed inside the pool robot body. The detachability can be achieved through methods such as fastening, adhesive bonding, binding, magnetic attraction, etc. Because the battery compartment is fixed inside the body, it will not detach unless subjected to strong vibration; the simple detachable design allows users to easily replace or maintain the battery compartment.

[0063] This embodiment provides a swimming pool robot with a double-layer shell and a cavity 14. The temperature and pressure inside the cavity 14 are monitored in real time, which can predict and judge the working status of the product, achieving the effect of real-time monitoring. The cavity 14 also saves the complicated process of applying glue to the entire cavity in the traditional way, while also saving costs and reducing the overall weight. When testing the product, only the temperature and pressure data need to be referenced, avoiding the complicated and tedious process of traditionally requiring pressure testing of each battery.

[0064] As we all know, the battery of a pool robot is a core module of the entire robot. Functionally, the structural design must ensure its underwater sealing (at a depth of 12 meters). From the user's perspective, its importance needs to be elevated to the highest level: because the environment in which it operates involves contact with more than 90% of the human body's skin, it involves extremely important safety.

[0065] Therefore, the underwater sealing of batteries needs to be treated with the utmost rigor and the highest level of safety. Based on knowledge of battery safety, the failure modes of pool robot batteries include the following:

[0066] 1) Battery Failure Mode Analysis:

[0067] (1) Water immersion: When the battery is submerged in water, the battery and protection board fail. The main control circuit can detect the battery damage and disconnects the main control circuit from the battery's charging power supply. This failure mode is not very hazardous.

[0068] (2) Water seepage: This leads to a short circuit in the battery. Without charging, the short circuit causes a chemical reaction in the battery. This reaction is relatively slow, and this failure mode is somewhat harmful.

[0069] (3) Water seepage + charging: This causes the battery to short-circuit. When charging, the short circuit causes a chemical reaction in the battery, which is accelerated when charging. This failure mode is the most harmful, and the chemical reaction of the battery will spread to the entire pool.

[0070] 2) Current mainstream solutions for underwater batteries:

[0071] (1) Sealing structure solution for underwater batteries: The safest solution is to first inject adhesive into the battery compartment and integrate it with the battery to form a sealed whole and achieve a sealing effect; in addition, structural adhesive is used on the outer shell to form a secondary seal.

[0072] (2) Advantages of the above process: The sealing of the outer shell structure adhesive can achieve a good sealing effect; the internal potting and resealing greatly reduces the probability of water ingress failure.

[0073] (3) Disadvantages of this process: The process control of internal potting can only be controlled up to the test sample, and cannot be controlled for each product; in addition, water ingress in the first layer of seal cannot be monitored in real time; its reliability is that all control is placed at the production end, and the rest is left to nature; the third point is that the potting process will lead to an increase in battery weight (weight increases by more than 25%) and cost (cost increases by more than 20%).

[0074] Through the improvements to the battery compartment and the sealing and control technology of this utility model, the following effects can be achieved.

[0075] (1) Battery sealing: Apply glue to the battery parting surface for more than 15mm, and still use structural glue to form a seal;

[0076] (2) A combination of pressure and temperature sensors is used to control the battery sealing cavity. This solution can effectively address the shortcomings of the above process and achieve real-time monitoring.

[0077] (3) Advantages of this solution: It makes the overall weight of the battery lighter by more than 20% and the cost reduced by more than 10%; the sealed cavity is monitored in real time, and the failure judgment is based on evidence; the production adopts a combination of pressure sampling inspection test (12m) and online reading of real-time data.

[0078] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
