Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, and in particular to a chemical spraying device for water tanks, water treatment equipment, and an automatic water tank cleaning robot. Background Technology

[0002] As people pay more attention to health issues, the demand for water quality management is also increasing. In the treatment of water bodies such as pools, the water quality is usually improved by adding chemicals to the pools.

[0003] Currently, there are two main methods for administering chemicals in water treatment: one is to deliver diluted liquid chemicals into the water body, and the other is to place solid chemicals (such as chlorine tablets) directly into the water for disinfection and purification. While the first method allows for rapid chemical administration, it faces challenges in practical applications, including large quantities of liquid chemicals required and high transportation and storage costs. This is especially true in the application of pool cleaning robots, where the limited carrying capacity often makes it difficult to deliver liquid chemicals to the pool, increasing operational complexity and costs. The second method involves placing solid chemicals into the water body. This method is simpler than the first and does not require a complex delivery system. However, its disadvantages include slow dissolution of solid chemicals, uncontrollable release of the chemicals, and potential uneven distribution of the chemicals in the water, affecting the water treatment effect.

[0005] Furthermore, the liquid inlet assembly includes a first valve, and the liquid outlet assembly includes a second valve. When the drive device is working, both the first valve and the second valve can be automatically opened.

[0006] Furthermore, the position of the dispensing component on the medicine box is higher than the position of the inlet component on the medicine box.

[0007] Furthermore, the power of the drive device can be adjusted.

[0008] Furthermore, the chemical spraying device for the water tank also includes a controller that can receive external control signals to adjust the power of the drive device.

[0009] Furthermore, the driving device includes a driving pump, which is connected to the inlet assembly or the outlet assembly.

[0010] Furthermore, the medicine box is also provided with a first channel, which is connected to the liquid dispensing component. The liquid outlet of the first channel is located at the bottom of the medicine box, and the liquid flowing out from the liquid dispensing component flows out of the medicine box through the first channel and the liquid outlet.

[0011] Furthermore, the interior of the medicine box is provided with a second channel, which includes a channel inlet and a channel outlet. The channel inlet is connected to the liquid inlet assembly, and the channel outlet is connected to the receiving cavity of the medicine box.

[0012] Furthermore, the length of the second channel is greater than one-third of the length of the shortest side of the medicine box.

[0013] Furthermore, the channel outlets include multiple outlets, which are spaced apart in the extending direction of the second channel.

[0014] Furthermore, the chemical dispensing device for the water tank also includes: a cover, which is detachably disposed at the chemical inlet, and the cover is used to seal or open the chemical inlet.

[0015] Furthermore, the bottom of the medicine box is provided with a liquid discharge section, which includes a liquid discharge hole and a liquid discharge cover; the liquid discharge hole is connected to the receiving cavity, and the liquid discharge cover is detachably provided on the liquid discharge hole, which is used to seal or open the liquid discharge hole.

[0016] Furthermore, the medicine box is provided with a mounting part, which allows the medicine dispensing device to be detachably installed on the main body of the water treatment equipment or the main body of the automatic water tank cleaning robot.

[0017] Furthermore, the chemical spraying device for the water tank also includes: a filter element, which is disposed inside the chemical box and covers the outside or inside of the liquid dispensing assembly. The filter element is provided with a filter screen, and the liquid in the receiving cavity flows to the liquid dispensing assembly through the filter screen.

[0018] According to a second aspect of this application, a water treatment device is provided, comprising a main body and a chemical spraying device for a water tank as described in any of the preceding claims, wherein the chemical spraying device for the water tank is installed on the main body, and the main body can be placed on the wall or bottom of the water tank.

[0019] According to a third aspect of this application, an automatic water tank cleaning robot is provided, comprising a main body and a chemical spraying device for water tanks as described in any of the preceding claims, wherein the chemical spraying device for water tanks is installed on the main body.

[0020] The embodiments described in this application have the following beneficial effects:

[0021] In this embodiment, the reagent box is equipped with a reagent addition port, which communicates with the receiving cavity of the reagent box. Reagent can be placed or added into the receiving cavity through the reagent addition port. When the reagent dispensing device is placed in a water tank and the water quality needs to be treated using the device, the driving device can drive liquid outside the reagent box (e.g., liquid inside the water tank) to flow into the receiving cavity of the reagent box through the liquid inlet assembly. This allows the flowing liquid to mix with the reagent in the receiving cavity, thereby dissolving or diluting the reagent. As the amount of liquid flowing into the receiving cavity increases, the dissolved or diluted reagent can flow out of the receiving cavity through the liquid outlet assembly and be released into the water tank, thus achieving the purpose of treating the water quality in the tank. This chemical spraying device can use solid chemicals or highly concentrated liquid chemicals for water treatment. Compared with using diluted liquid chemicals, it requires less load-bearing capacity from the spraying device, reducing operational difficulty and cost. Furthermore, by dissolving or diluting solid chemicals or highly concentrated liquid chemicals before releasing them into the water body to be treated, this device improves the uniformity of chemical spraying compared to directly adding solid chemicals or highly concentrated liquid chemicals to the water body.

[0033] The technical solutions in this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0034] This application provides a chemical spraying device 10 (hereinafter referred to as chemical spraying device 10) for use in a water tank, such as... Figures 1 to 6 As shown, the pesticide application device 10 includes a pesticide container 100, a liquid inlet assembly 200, a liquid outlet assembly 300, and a driving device. The pesticide container 100 has a pesticide inlet 120, which communicates with the receiving cavity 110 of the pesticide container 100. The liquid inlet assembly 200 is mounted on the pesticide container 100, allowing external liquid to flow into the receiving cavity 110. The liquid outlet assembly 300 is mounted on the pesticide container 100, allowing liquid in the receiving cavity 110 to flow out of the pesticide container 100. The driving device is connected to the liquid inlet assembly 200, or the driving device is connected to the liquid outlet assembly 300, and is used to drive external liquid through the liquid inlet assembly 200 into the receiving cavity 110, and then through the liquid outlet assembly 300 out of the receiving cavity 110.

[0035] The reagent box 100 is provided with a reagent addition port 120, which is connected to the receiving cavity 110 of the reagent box 100. A reagent (e.g., a solid reagent or a highly concentrated liquid reagent) can be placed or added into the receiving cavity 110 through the reagent addition port 120. An inlet assembly 200 and an outlet assembly 300 are respectively provided on the reagent box 100. A driving device can be connected to the inlet assembly 200, or alternatively, to the outlet assembly 300. When the reagent dispensing device 10 is placed in a water tank and the water quality needs to be treated by the reagent dispensing device 10, the driving device can drive liquid outside the reagent box 100 (e.g., water in the water tank) to flow into the receiving cavity 110 of the reagent box 100 through the inlet assembly 200. The externally flowing liquid, upon contact with the reagent in the receiving cavity 110, can dissolve the solid reagent in the receiving cavity 110 or dilute the highly concentrated liquid reagent in the receiving cavity 110. As external liquid continuously flows into the receiving cavity 110 through the liquid inlet assembly 200, the amount of liquid in the receiving cavity 110 gradually increases. After the liquid agent produced by dissolution or dilution in the receiving cavity 110 reaches the position of the liquid outlet assembly 300, under the action of the driving device, the liquid agent produced by dissolution or dilution can flow out of the receiving cavity 110 through the liquid outlet assembly 300 to be released into the water tank to treat the water quality in the water tank.

[0036] This chemical spraying device can use solid chemicals or highly concentrated liquid chemicals for water treatment. Compared with using diluted liquid chemicals, it requires less load-bearing capacity from the spraying device, reducing operational difficulty and cost. Furthermore, by dissolving or diluting solid chemicals or highly concentrated liquid chemicals before releasing them into the water body to be treated, this device improves the uniformity of chemical spraying compared to directly adding solid chemicals or highly concentrated liquid chemicals to the water body.

[0037] It is understood that the pool described above can be a pool-shaped structure, such as a swimming pool, a water storage tank, a spa pool, a water storage tank, or a water storage trough.

[0038] For example, the drive device includes a drive pump connected to the inlet assembly 200 or the outlet assembly 300.

[0039] The following explanation uses the connection between the drive pump and the liquid inlet assembly 200 as an example.

[0040] When the drive pump is working, it can drive external liquid (such as water in a pool) into the receiving cavity 110 through the liquid inlet assembly 200. As the external liquid continuously flows into the receiving cavity 110 through the liquid inlet assembly 200, the liquid agent produced after dissolution or dilution in the receiving cavity 110 will reach the location of the liquid outlet assembly 300. At this time, as the drive pump continues to inject liquid into the receiving cavity, the hydraulic pressure in the receiving cavity 110 will continue to increase, making the hydraulic pressure in the receiving cavity 110 greater than the hydraulic pressure outside the receiving cavity 110, so that the liquid agent produced after dissolution or dilution in the receiving cavity 110 can flow out of the receiving cavity 110 through the liquid outlet assembly 300.

[0041] The following explanation uses the connection between the drive pump and the liquid outlet assembly 300 as an example.

[0042] When the drive pump is working, it generates suction in the receiving cavity 110 through the liquid outlet assembly 300. When the receiving cavity 110 contains only solid reagent or a small amount of high-concentration liquid reagent, the suction generated by the drive pump gradually reduces the air pressure inside the receiving cavity 110. When the pressure inside the receiving cavity 110 is lower than the water pressure outside the receiving cavity 110, liquid outside the receiving cavity 110 (such as water in a pool) can enter the receiving cavity 110 through the liquid inlet assembly 200. As the drive pump continues to work, the amount of liquid entering the receiving cavity 110 through the liquid inlet assembly 200 continuously increases. When the liquid reagent produced after dissolution or dilution in the receiving cavity 110 reaches the position of the liquid outlet assembly 300, the liquid inside the receiving cavity 110 will flow out of the receiving cavity 110 through the liquid outlet assembly 300 under the action of the drive pump.

[0043] like Figure 2 and Figure 3 As shown, the liquid inlet assembly 200 may include a first valve 210, and the liquid outlet assembly 300 may include a second valve 310. When the drive device is working, both the first valve 210 and the second valve 310 can be opened automatically.

[0044] When the drive device is working, both the first valve 210 and the second valve 310 can be opened automatically, so that the drive device can smoothly drive the liquid from the first valve 210 into the receiving cavity 110, and smoothly drive the liquid medicine in the receiving cavity 110 to flow out of the receiving cavity 110 through the liquid outlet assembly 300. This setting does not require manual operation by the user, which improves the convenience of use.

[0045] The following explanation will take the connection between the drive device and the liquid inlet assembly 200 as an example.

[0046] For example, the first valve 210 can be a first check valve, and the second valve 310 can be a second check valve. When the driving device drives the external liquid to flow into the receiving cavity 110, the first check valve is unidirectionally opened from the outside to the inside of the receiving cavity 110 under the action of the external liquid flow force. At this time, the external liquid flows into the receiving cavity 110 through the first check valve. As the external liquid continues to flow into the receiving cavity 110 through the first check valve, the liquid agent generated after dissolution or dilution in the receiving cavity 110 will reach the location of the second check valve. At this time, when the driving pump continues to inject liquid into the receiving cavity, the hydraulic pressure in the receiving cavity 110 will continue to increase, making the hydraulic pressure in the receiving cavity 110 greater than the hydraulic pressure outside the receiving cavity 110. At this time, the second check valve is unidirectionally opened from the inside to the outside of the receiving cavity 110, so that the liquid agent generated after dissolution or dilution in the receiving cavity 110 can flow out of the receiving cavity 110 through the liquid outlet assembly 300.

[0047] When no medication needs to be added or when medication addition is complete, the control drive device stops working, and the first check valve closes without being subjected to the flow force of external liquid. At this time, no liquid flows into the receiving cavity 110, and the pressure inside the receiving cavity 110 reaches equilibrium with the outside. The second check valve also closes, which can reduce the occurrence of liquid leakage in the receiving cavity 110 and improve the sealing performance of the medication dispensing device 10.

[0048] For example, the first valve 210 can be a first solenoid valve, and the second valve 310 can be a second solenoid valve. When the driving device drives the external liquid to flow into the receiving cavity 110, the first and second solenoid valves can be controlled to open synchronously, and the external liquid flows into the receiving cavity 110 through the first solenoid valve. As the external liquid continues to flow into the receiving cavity 110 through the first solenoid valve, the dissolved or diluted liquid agent in the receiving cavity 110 will reach the location of the second solenoid valve. At this time, when the driving pump continues to inject liquid into the receiving cavity, the hydraulic pressure in the receiving cavity 110 will continue to increase, making the hydraulic pressure in the receiving cavity 110 greater than the hydraulic pressure outside the receiving cavity 110. Under the pressure of the internal liquid solvent, the dissolved or diluted liquid agent in the receiving cavity 110 can flow out of the receiving cavity 110 through the liquid outlet assembly 300. When the agent is not needed or the agent is dispensed, the control drive device stops working. At this time, the first solenoid valve and the second solenoid valve can be closed simultaneously. This can reduce the leakage of liquid in the receiving cavity 110 through the liquid inlet assembly 200 and improve the sealing performance of the agent dispensing device 10.

[0049] It is understood that the above description of the first valve 210 and the second valve 310 is merely exemplary. Alternatively, the first valve 210 can be configured as a first check valve and the second valve 310 as a second solenoid valve, or the first valve 210 can be configured as a first solenoid valve and the second valve 310 as a second check valve. The specific implementation of the first valve 210 and the second valve 310 can be set according to the specific specifications and operational requirements of the pesticide application device 10, or based on the experience of those skilled in the art. As long as both the first valve 210 and the second valve 310 can automatically open when the driving device is operating, this application does not impose any specific limitations.

[0050] For example, such as Figure 6 As shown, the position of the liquid dispensing component 300 on the medicine box 100 can be higher than the position of the liquid inlet component 200 on the medicine box 100.

[0051] When the liquid agent in the receiving cavity 110 reaches the inlet of the dispensing component 300, it can flow out through the dispensing component 300 under the action of the driving device. The position of the dispensing component 300 on the agent box 100 is higher than that of the inlet component 200 on the agent box 100. That is to say, the liquid entering the receiving cavity 110 needs to accumulate to a certain volume in the receiving cavity 110 before it can flow out through the dispensing component 300. This can increase the amount and time of liquid remaining in the receiving cavity 110, improve the dissolution efficiency and uniformity of the agent, and thus improve the dispensing effect of the agent dispensing device 10.

[0052] For example, the liquid inlet assembly 200 can be located at the lower part of the medicine box 100, and the liquid outlet assembly 300 can be located at the middle or upper part of the medicine box 100. Alternatively, the liquid inlet assembly 200 can be located at the middle part of the medicine box 100, and the liquid outlet assembly 300 can be located at the upper part of the medicine box 100. It is understood that the above-mentioned positions of the liquid inlet assembly 200 and the liquid outlet assembly 300 on the medicine box 100 are merely illustrative. The specific positions of the liquid inlet assembly 200 and the liquid outlet assembly 300 on the medicine box 100 can be set according to the required liquid retention volume in the receiving cavity 110, or according to the specifications of the medicine box 100, as long as the position of the liquid outlet assembly 300 on the medicine box 100 is higher than the position of the liquid inlet assembly 200 on the medicine box 100. No specific limitation is made here.

[0053] For example, the power of the drive unit can be adjusted.

[0054] The power of the drive device can be adjusted, meaning that by adjusting the power of the drive device, the flow rate of the liquid flowing into the receiving cavity 110 can be changed, thereby altering the pesticide dispensing flow rate of the pesticide dispensing device 10. This allows the power of the drive device to be adaptively adjusted according to different pesticide types, pool sizes, total pesticide dispensing volume, or dispensing time, to meet various dispensing needs and improve the adaptability and versatility of the pesticide dispensing device 10. In other words, the pesticide dispensing flow rate of the pesticide dispensing device 10 can be controlled by controlling the flow rate of the liquid flowing into the receiving cavity 110.

[0055] For example, the pesticide application device 10 may also include a controller that can receive external control signals to adjust the power of the drive device.

[0056] The controller can be electrically and / or communicatively connected to the drive unit. The controller can accept external control signals and adjust the power of the drive unit according to the external control signals so that the power of the drive unit can be adjusted according to the usage requirements, thereby improving the adaptability and versatility of the pesticide spraying device 10.

[0057] For example, the external control signal can be sent by the operator to the controller through a control terminal device. Alternatively, when the chemical spraying device 10 is applied to a water treatment device or an automatic pool cleaning robot 20, the external control signal can also be sent by the water treatment device or the automatic pool cleaning robot 20 to the controller. For instance, the water treatment device or the automatic pool cleaning robot 20 sends a corresponding control signal to the controller based on the detected water quality of the pool water to adjust the power of the drive device, thereby achieving refined treatment of the pool. The controller may include a communication module through which the controller can receive external control signals in a timely manner. It is understood that the above description of the sender of the external control signal is merely exemplary, and the specific sender can be set according to the specific application scenario or usage requirements of the chemical spraying device 10. This application does not impose specific limitations on this.

[0058] For example, such as Figure 2 As shown, the medicine box 100 is also provided with a first channel 130, which is connected to the liquid dispensing assembly 300. The liquid outlet of the first channel 130 is located at the bottom of the medicine box 100. The liquid flowing out from the liquid dispensing assembly 300 flows out of the medicine box 100 through the liquid outlet of the first channel 130.

[0059] The first channel 130 connects to the liquid outlet assembly 300, and the outlet of the liquid outlet assembly 300 can connect to the inlet of the first channel 130. The liquid mixed with the agent discharged from the liquid outlet assembly 300 can flow out of the agent box 100 through the outlet of the first channel 130. The outlet of the first channel 130 can be located at the bottom of the agent box 100, so that the liquid mixed with the agent can flow directly downwards from the first channel 130 to the agent dispensing device 10, thereby reducing contact between the liquid mixed with the agent and the outer wall of the agent box 100, the water treatment equipment on which the agent dispensing device 10 is installed, or the automatic water cleaning robot 20 on which the agent dispensing device 10 is installed. Since the liquid mixed with the agent has a strong acidity or alkalinity, this can reduce the occurrence of corrosion or even damage to the outer wall of the agent box 100, the water treatment equipment, or the automatic water cleaning robot 20 by the liquid agent flowing out of the agent box 100, thus improving the safety and service life of the agent dispensing device 10.

[0060] For example, such as Figure 3 , Figure 4 and Figure 6 As shown, the medicine box 100 is also provided with a second channel 400 inside. The second channel 400 includes a channel inlet 410 and a channel outlet 420. The channel inlet 410 is connected to the liquid inlet assembly 200, and the channel outlet 420 is connected to the receiving cavity 110 of the medicine box 100.

[0061] The inlet 410 of the second channel 400 is connected to the outlet of the liquid inlet assembly 200, and the outlet 420 of the second channel 400 is connected to the receiving cavity 110 of the medicine box 100. The second channel 400 can guide the external liquid flowing in from the liquid inlet assembly 200 to flow out from a specific position in the receiving cavity 110.

[0062] The second channel 400 may extend within the receiving cavity 110. For example, the second channel 400 may extend along the shortest side of the medicine box 100, or along the longest side of the medicine box 100, or it may extend obliquely within the receiving cavity 110. It is understood that the extension direction of the second channel 400 described above is merely exemplary and is not specifically limited herein.

[0063] The length of the second channel 400 can, for example, be greater than one-third of the length of the shortest side of the medicine box 100.

[0064] This arrangement, with the channel outlet 420 extending from the end of the second channel 400, allows liquid to be transported to the central position within the receiving cavity 110, enabling the liquid flowing out of the second channel 400 to spread outwards from the center of the receiving cavity 110, thereby improving the uniformity of liquid mixing. For example, the length of the second channel 400 can also be one-half, two-thirds, or three-quarters of the length of the shortest side of the medicine box 100, or the length of the second channel 400 can be greater than or equal to the length of the shortest side of the medicine box 100. The length of the second channel 400 can be less than or equal to the length of the uppermost side of the medicine box 100.

[0065] It is understood that the above description of the length of the second channel 400 is merely exemplary. The specific length of the second channel 400 can be set according to the specific specifications of the medicine box 100, the type of medicine to be dissolved, or the power range of the driving device, as long as the length of the second channel 400 is greater than one-third of the length of the shortest side of the medicine box 100. No specific limitation is made here.

[0066] For example, such as Figure 4 As shown, the channel outlet 420 includes multiple outlets, which are spaced apart in the extension direction of the second channel 400.

[0067] The second channel 400 may include multiple channel outlets 420, which may be spaced apart in the extending direction of the second channel 400. This allows the second channel 400 to discharge liquid to multiple locations within the receiving cavity 110, increasing the range of water flow impacting the agent discharged from the channel outlets 420 and increasing the turbulence effect of the liquid within the receiving cavity 110, thereby improving the dissolution effect of the agent and the uniformity of its distribution within the receiving cavity 110.

[0068] Furthermore, at least some of the channel outlets 420 may be located at different heights on the second channel 400. For example, some channel outlets 420 may be located on the top wall of the second channel 400, while others may be located on the side wall. This arrangement allows the liquid flowing out of the second channel 400 to impact the agent from different heights, increasing the disorder of the liquid flow within the receiving cavity 110, thereby improving the dissolution effect of the agent and the uniformity of its distribution within the receiving cavity 110.

[0069] For example, such as Figure 2 and Figure 3 As shown, the pesticide application device 10 may also include a cover 500, which is detachably disposed at the pesticide inlet 120 and is used to seal or open the pesticide inlet 120.

[0070] The cover 500 is detachably mounted on the pesticide inlet 120. When pesticide needs to be added to the receiving cavity 110, the pesticide inlet 120 can be opened through the cover 500, and pesticide can then be added to the receiving cavity 110 through the pesticide inlet 120, enabling the pesticide dispensing device 10 to be reused and reducing costs. When the pesticide dispensing device 10 is in operation, the cover 500 can seal the pesticide inlet 120 to reduce the occurrence of liquid mixed with pesticide or even pesticide flowing directly out of the pesticide inlet 120, thereby improving the operational stability and reliability of the pesticide dispensing device 10.

[0071] like Figure 3 , Figure 5 and Figure 6 As shown, the bottom of the medicine box 100 may also be provided with a liquid discharge section, which includes a liquid discharge hole 140 and a liquid discharge cap 600. The liquid discharge hole 140 communicates with the receiving cavity 110, and the liquid discharge cap 600 is detachably provided on the liquid discharge hole 140. The liquid discharge cap 600 is used to seal or open the liquid discharge hole 140.

[0072] Because the liquid outlet assembly 300 is positioned higher than the liquid inlet assembly 200, liquid will remain in the receiving cavity 110 after the drive device is turned off. At this time, the liquid outlet hole 140 at the bottom of the medicine box 100 can be opened through the liquid outlet cap 600 to allow the liquid in the receiving cavity 110 to drain smoothly from the hole 140. Furthermore, clean liquid can be injected into the receiving cavity 110 through the liquid outlet hole 140 to clean the inside of the receiving cavity 110, preventing contamination when different types of medicines are placed inside, thus improving the versatility of the medicine dispensing device 10. When the drive device is operating, the liquid outlet cap 600 can seal the liquid outlet hole 140 to reduce the occurrence of solid and / or liquid medicines flowing out of the receiving cavity 110 from the liquid outlet hole 140 before the medicines are fully dissolved or diluted, thereby improving the stability and reliability of the medicine dispensing device 10.

[0073] like Figures 1 to 4 As shown, the medicine box 100 may be provided with a mounting part 700, which allows the medicine dispensing device to be detachably installed on the main body of the water treatment equipment or the main body of the automatic water tank cleaning robot 20.

[0074] The reagent cartridge 100 can be detachably mounted on the main body of the water treatment equipment or the main body of the automatic pool cleaning robot 20 via the mounting part 700. For example, when water treatment is required, the reagent cartridge 100 can be mounted on the main body of the water treatment equipment or the main body of the automatic pool cleaning robot 20 via the mounting part 700, allowing the reagent dispensing device 10 to be mounted on the water treatment equipment or the automatic pool cleaning robot and operate inside the pool to dispense the reagent through the liquid in the pool.
