[0040] The solution provided by this invention has the following advantages compared with the prior art:

[0041] Through the above technical solution, the foam generating device is equipped with a first dispensing component. Through this component, the laundry detergent and water can be fully mixed in the first foaming chamber to generate foam, forming a foam liquid which is then discharged from the first foam outlet. The laundry detergent can be used as a washing agent. When the foam generating device is applied to washing equipment, the fabric to be treated is clothing. Compared to manually adding the laundry detergent during washing, the foam liquid is directly dispensed into the washing container by the foam generating device. This allows the foam liquid to directly contact the clothing, ensuring effective washing and reducing the time the laundry detergent spends dissolving in water, thus improving the user experience. The liquid supply component dispenses a certain amount of laundry detergent water into the first foaming chamber. This laundry detergent water refers to a mixture of laundry detergent and water. When the pressurized laundry detergent water flows out from the liquid supply component, the pressure causes it to foam. The mixture of laundry detergent and water then enters the first foaming chamber and is further foamed by the foaming component, further increasing the foam generated within the first foaming chamber. The foaming component within the first foaming chamber uses pressurized foaming gas to impact the water-based laundry detergent entering the chamber, further foaming it and forming a foam liquid. Simultaneously, the supply of laundry detergent water to the first foaming chamber ensures that the detergent dissolves fully in the water upon entering and during the foaming process, allowing for thorough mixing and reducing the dissolution time of the detergent, thus facilitating foam formation. Furthermore, the foam liquid is discharged from the first foam outlet with jet pressure. This jet pressure breaks down larger bubbles as they flow out of the first outlet, resulting in a finer foam liquid. The first foaming chamber is configured as a positive pressure chamber during foam generation, ensuring the continued flow of the foam liquid.

[0042] Other features and advantages of the present disclosure will be described in detail in the following detailed description. Attached Figure Description

[0054] To address the problem that existing washing machines require users to manually add laundry detergent, which often fails to guarantee effective washing of the fabrics, this application provides a foam generating device that is both compact and ensures effective washing of the fabrics. Specifically, this application incorporates a first dispensing component and a second dispensing component. While retaining the option for users to manually add laundry detergent, the first dispensing component ensures precise dosage of the detergent, and the foaming component promotes the dissolution of the detergent and generates foam liquid, thereby improving the cleaning effect of the detergent and effectively guaranteeing the washing results of the fabrics.

[0055] According to the first embodiment provided in this application, as Figures 1 to 3As shown, a foam generating device is provided for a washing device 1. The washing device 1 is provided with a washing container 101 for treating fabrics to be treated. The foam generating device includes a first dispensing component for providing foam liquid containing a laundry detergent into the washing container 101. The first dispensing component includes a first foaming chamber 201, a liquid supply component, and a foaming component. The first foaming chamber 201 is provided with a first foam outlet 204. The liquid supply component is used to provide pressurized laundry detergent water into the first foaming chamber 201. The foaming component is used to provide pressurized gas into the first foaming chamber 201 to cause the laundry detergent water to foam and form foam liquid. The first foaming chamber 201 is configured as a positive pressure chamber when the foam generating device is in use, and the foam liquid is discharged outward from the first foam outlet 204 with a spray pressure.

[0056] Through the above technical solution, the foam generating device is equipped with a first dispensing component. Through this component, the laundry detergent and water can be fully mixed in the first foaming chamber 201 to generate foam, forming a foam liquid which is then discharged outwards from the first foam outlet 204. The laundry detergent can be used as a washing agent. When the foam generating device is applied to a washing machine 1 for washing clothes, the fabric to be treated is clothing. Compared to manually adding the laundry detergent during washing, the foam liquid is directly dispensed into the washing container 101 by the foam generating device. This allows the foam liquid to directly contact the clothing, ensuring a good washing effect and reducing the time the laundry detergent takes to dissolve in water, thus improving the user experience. The liquid supply component can dispense a certain amount of laundry detergent water into the first foaming chamber 201. This laundry detergent water refers to a mixture of laundry detergent and water. When the pressurized laundry detergent water flows out from the liquid supply component, the pressure causes the laundry detergent water to generate foam. The liquid, composed of laundry detergent and water, enters the first foaming chamber 201 and is further foamed by the foaming component, increasing the foam generated within the chamber. The foaming component in the first foaming chamber 201 uses pressurized foaming gas to impact the liquid laundry detergent entering the chamber, causing it to further foam and form a foam liquid. Simultaneously, the liquid laundry detergent is supplied to the first foaming chamber 201. This ensures that the laundry detergent dissolves fully in the water upon entering and during the foaming process, allowing for thorough mixing and reducing the dissolution time of the detergent, thus facilitating the formation of a foam liquid. Furthermore, the foam liquid is discharged outward from the first foam outlet 204 with a jet pressure. The jet pressure will cause the larger foams in the foam liquid to be broken when they flow out from the first foam outlet 204, making the foam liquid flowing out from the first foam outlet 204 more delicate. The first foaming chamber 201 is configured as a positive pressure chamber when the foam generating device is in use, which also ensures the outflow of foam liquid.

[0057] It should be noted that the interconnection between the two mentioned above and below refers to the ability of gas or liquid to flow between them, and does not indicate or limit the connection relationship between them. The aforementioned foaming component is used to supply pressurized gas into the first foaming chamber 201 to cause the laundry detergent water to foam and form a foam liquid. This means that the foaming component can supply pressurized gas into the first foaming chamber 201, causing the laundry detergent water to foam, thus turning the laundry detergent water into a foam liquid, which is formed by mixing the laundry detergent and water.

[0058] The first dispensing component may further include a second foaming chamber 202 connected in series with the first foaming chamber 201 via a first foam outlet 204. The liquid supply component simultaneously supplies laundry detergent water to both the first and second foaming chambers 201 and 202. Here, "simultaneously" means that the liquid supply component can supply laundry detergent water to both the first and second foaming chambers 201 and 202. The second foaming chamber 202 may be located downstream of the first foaming chamber 201, meaning downstream of the foam liquid flow path within the first foaming chamber 201. The second foaming chamber 202 increases the flow path of the foam liquid, allowing the laundry detergent and water to mix and dissolve thoroughly. Simultaneously, the increased flow path also allows larger bubbles to break up during flow, further increasing the fineness of the foam liquid. The liquid supply assembly simultaneously supplies the laundry detergent water to the first foaming chamber 201 and the second foaming chamber 202. The water entering the second foaming chamber 202 can also increase the fluidity of the foam liquid, making it easier for the foam liquid to flow out from the foam outlet 211, and preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long, which would cause defoaming.

[0059] The second foaming chamber 202 can be configured as a positive pressure chamber when the foam generating device is in use. The second foaming chamber 202 is provided with a second foam outlet 205, from which the foam liquid is discharged outward with jet pressure. Specifically, the second foaming chamber 202 can be provided with the second foam outlet 205 on the side away from the first foam outlet 204, thus maximizing the flow path of the foam liquid within the first foaming chamber 201. The foam liquid is discharged outward from the second foam outlet 205 with jet pressure. The second foaming chamber 202 is configured as a positive pressure chamber when the foam generating device is in use, ensuring that the foam liquid can be discharged from the second foam outlet 205 with jet pressure. The jet pressure causes the larger foams in the foam liquid to break up as they flow out of the second foam outlet 205, resulting in a finer foam liquid flowing out of the second foam outlet 205.

[0060] The second foam outlet 205 and the first foam outlet 204 can be configured such that the flow path of the foam liquid from the first foam outlet 204 to the second foam outlet 205 in the second foaming chamber 202 is a bend. This bend ensures that the flow of the foam liquid is not too slow, while also reducing the flow speed to a certain extent. This allows larger bubbles in the foam liquid to break up, further increasing the fineness of the foam liquid.

[0061] The first dispensing component may further include a third foaming chamber 203 connected in series with the second foaming chamber 202 via a second foam outlet 205. The third foaming chamber 203 has a discharge port 211 connected to the first foaming chamber 201. The third foaming chamber 203 may be configured as a positive pressure chamber when the foam generating device is in use, with foam liquid being discharged outward from the discharge port 211 and having spray pressure. Preferably, the third foaming chamber 203 may be located downstream of the second foaming chamber 202 and connected in series with the second foam outlet 205, where downstream refers to the downstream of the foam liquid flow path within the second foaming chamber 202.

[0062] The third foaming chamber 203 is configured as a positive pressure chamber when the foam generating device is in use, ensuring that the foam liquid is discharged outward from the outlet 211 with spray pressure. This third foaming chamber 203 further increases the flow path of the foam liquid, allowing the laundry detergent and water to mix and dissolve thoroughly. Simultaneously, the increased flow path also allows larger bubbles to break down during flow, further increasing the fineness of the foam liquid. Furthermore, the spray pressure from the outlet 211 causes larger bubbles to break down as they flow out, resulting in a finer foam liquid and ensuring that the foam liquid generated within the foam generating device is discharged. Thus, the foam liquid formed in the first foaming chamber 201, after passing through the first outlet 204, the second outlet 205, and the outlet 211, becomes finer, ensuring a superior washing effect on clothes.

[0063] The foam generating device may further include a first partition chamber 206 that communicates with the first foaming chamber 201 and the second foaming chamber 202 respectively. The first partition chamber 206 forms a first spray port 208 on the side facing the first foaming chamber 201 and a second spray port 209 on the side facing the second foaming chamber 202. The liquid supply assembly simultaneously supplies laundry detergent water to the first foaming chamber 201 and the second foaming chamber 202 through the first spray port 208 and the second spray port 209. The liquid supply assembly simultaneously supplies laundry detergent water to the first foaming chamber 201 and the second foaming chamber 202 through the first partition chamber 206. The water entering the second foaming chamber 202 can increase the fluidity of the foam liquid, making it easier for the foam liquid to flow out from the foam discharge port 211, and preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long, which would cause defoaming. Meanwhile, the first partition chamber 206 can be set between the first foaming chamber 201 and the second foaming chamber 202, making the structure of the first partition chamber 206 more compact, and one first partition chamber 206 can supply water to the first foaming chamber 201 and the second foaming chamber 202 at the same time.

[0064] In some embodiments, multiple first spray nozzles 208 may be provided, with at least one first spray nozzle 208 spraying laundry detergent water toward the bottom of the first foaming chamber 201 to create turbulence within the first foaming chamber 201. When the laundry detergent water is sprayed to the bottom at a certain speed and angle, it carries the surrounding liquid along with it, forming a complex flow field. This turbulence not only helps the laundry detergent to be distributed more evenly within the foaming chamber but also increases its contact area with the foaming gas, thereby accelerating foam generation. Furthermore, the synergistic effect of multiple spray nozzles can improve the utilization efficiency of the laundry detergent water, reduce unnecessary waste, and allow the laundry detergent to mix more thoroughly with the water for foaming. It also helps the laundry detergent water mix better with the foaming gas, thereby generating more foam.

[0065] In other embodiments, the foam generating device may further include a second partition chamber 207 communicating with the first foaming chamber 201. A liquid supply assembly supplies laundry detergent water to the first foaming chamber 201 through the second partition chamber 207. The second partition chamber 207 is located opposite the first partition chamber 206. A third spray nozzle 210 is formed on the side of the second partition chamber 207 facing the first foaming chamber 201, and the third spray nozzle 210 is positioned opposite to the first spray nozzle 208. In this way, the laundry detergent water sprayed from the first spray nozzle 208 and the laundry detergent water sprayed from the third spray nozzle 210 can collide and mix with each other, resulting in a more complex flow pattern of the laundry detergent water within the foaming chamber. This further enables the laundry detergent water to generate more foam, and further enables the foam liquid to generate more foam. Furthermore, the presence of the second partition chamber 207 can also buffer and regulate the flow rate of the laundry detergent water, ensuring the stability and continuity of the foaming process. The third spray nozzle 210 and the first spray nozzle 208 also enable the foam generating device to maintain high efficiency and stable performance when processing large amounts of laundry detergent water.

[0066] A blocking structure can be provided inside the first foaming chamber 201. When the laundry detergent water enters the first foaming chamber 201 from the first spray port 208, at least a portion of the laundry detergent water is sprayed onto the blocking structure. When the laundry detergent water enters the first foaming chamber 201 from the first spray port 208, at least a portion of the laundry detergent water will splash onto the blocking structure. The energy from the splashing will cause the laundry detergent water to generate foam, further increasing the turbulence and mixing of the laundry detergent water, thereby generating more foam. The blocking structure here is a perforated plate. This allows the laundry detergent water sprayed from the first spray port 208 to contact the side plate of the plate to generate foam, and the laundry detergent water sprayed from the first spray port 208 can also impact each other through the perforations to form foam. At the same time, the presence of the blocking structure also prevents the laundry detergent water from directly impacting the cavity wall of the first foaming chamber 201, reducing energy loss and noise pollution.

[0067] The first foaming chamber 201 may also be equipped with a water inlet connected to an external water source to replenish water during the foaming process of the laundry detergent. This allows water to be replenished into the first foaming chamber 201 through the inlet and external water source during foaming, ensuring stable foam generation while also promoting foam flow and preventing excessive residence time of the foam in the first, second, and third foaming chambers 201 and 202, which could lead to defoaming. Water replenishment also prevents a decline in foam quality due to insufficient moisture. The water inlet's replenishment function not only improves foam generation efficiency and stability but also enables the foam generator to operate continuously and stably, extending its service life. Furthermore, the design of the water inlet can be adjusted and optimized according to actual needs to adapt to the water quality and quantity requirements of different application scenarios.

[0068] The first foaming chamber 201 may be equipped with a rotatable turbulence structure to agitate the laundry detergent water. The turbulence structure can agitate the laundry detergent water, and the eddies and shear forces generated by the turbulence structure during rotation allow the laundry detergent water to come into more thorough contact with the foaming gas, increasing the mixing degree between the laundry detergent water and the foaming gas, thereby generating more foam.

[0069] The foaming assembly may include a first foaming element 301 disposed at the first foam outlet 204 and / or a second foaming element 302 disposed at the second foam outlet 205, for increasing the fineness of the foam in the foaming liquid. Specifically, the first foaming element 301 and / or the second foaming element 302 may be a mesh structure with a pore size of 50-500 mesh. The first foaming element 301 and / or the second foaming element 302 can filter out larger foam particles, which not only improves the fineness and stability of the foam but also enhances its durability and practicality. Simultaneously, when the foaming liquid passes through the second foaming element 302, the second foaming element 302 generates a certain resistance, further slowing down the flow rate of the foaming liquid and promoting its residence within the first foaming chamber 201, thus enabling the generation of more foam within the first foaming chamber 201.

[0070] The foaming assembly may include an air pump 304 connected to an external air source 303, a one-way valve 305, and a foaming element 306 disposed within a first foaming chamber 201. The foaming element 306 is connected to the external air source 303 via the one-way valve 305. Multiple foaming holes 307 are formed on the inner wall of the foaming element 306 for injecting pressurized foaming gas into the first foaming chamber 201. Gas from the external air source 303 is discharged through the foaming element 306 from the foaming holes 307, causing the liquid in the first foaming chamber 201 to foam. The gas discharged from the foaming holes 307 also agitates the liquid in the first foaming chamber 201, promoting the dissolution of the fabric treatment agent in the liquid. The external air source 303 can be connected to the foaming element 306 via the one-way valve 305 to prevent the liquid in the first foaming chamber 201 from flowing back into the external air source 303 through the foaming holes 307. The air pump 304 increases the gas volume within the foaming element 306, ensuring that the gas discharged from the foaming holes 307 carries a certain pressure, allowing the gas to fully agitate the laundry detergent water. Preferably, the foaming element 306 can be constructed as a hollow tube.

[0071] In some embodiments, the pore size of the foaming pores 307 can be 0.01 mm to 1 mm. Designing the pore size of the foaming pores 307 to be between 0.01 mm and 1 mm ensures that the foaming gas is injected into the first foaming chamber 201 at an appropriate pressure and flow rate, thereby generating an ideal foam effect. This design not only improves the efficiency and quality of foam generation but also enhances the versatility and applicability of the foam generating device. Simultaneously, the smaller foaming pores 307 also allow pressurized gas to be formed at the foaming port even at slower flow rates.

[0072] The pressurized gas supplied to the foam generating device can be ozone gas. Ozone has a sterilizing effect, and the ozone generating device can also provide additional oxidation and disinfection functions to the foam. Thus, the foam liquid produced by the first injection component is a foam liquid with a sterilizing effect, improving the hygiene and safety of the foam. This further ensures the washing effect on the fabrics to be treated. Besides ozone, in this application, the pressurized gas supplied to the foam generating device can also be other gases with sterilizing effects. This application limits the type of gas and ensures that it will not damage clothing or the human body.

[0073] The foaming component can be configured to supply pressurized foaming gas when the liquid supply component supplies pressurized laundry detergent water to the first foaming chamber 201. This can improve the foaming efficiency of the foam generating device and reduce the time required to generate foam liquid.

[0074] The liquid supply assembly may include an inlet pipe 401, a storage chamber 402, and a dispensing pump 403. A pressurization device 404 is installed on the inlet pipe 401. The inlet pipe 401 is connected to both the first foaming chamber 201 and the storage chamber. The storage chamber 402 stores the laundry detergent. The dispensing pump 403 is located between the storage chamber and the inlet pipe 401 and is used to draw the laundry detergent into the inlet pipe 401. By adjusting the opening degree and opening time of the dispensing pump 403, the content of laundry detergent entering the first dispensing assembly can be adjusted. Multiple storage chambers 402 can be provided to store different types of laundry detergents. Correspondingly, multiple dispensing pumps 403 can be provided, corresponding to the number of storage chambers 402, with a one-to-one correspondence between them. Thus, for each type of laundry detergent, a corresponding dispensing pump 403 is provided for control. The water inlet pipe 401 can be connected to the first partition chamber 206 and the second partition chamber 207 mentioned above, so that the water inlet pipe 401 can be connected to the first foaming chamber 201. At the same time, the pressurization device 404 can ensure the spray pressure of the laundry detergent water.

[0075] The foam generating device also includes a second dispensing component for dispensing the laundry detergent into the washing container 101. The second dispensing component includes a dispensing chamber 501, which can be selectively connected to the outside of the washing equipment 1. The dispensing chamber 501 has a drain port 506 connected to the washing container 101. When the fabric to be treated is only lightly soiled or there is only a small amount of fabric to be treated, i.e., when the fabric does not require a strong washing effect, the user can also manually dispense the laundry detergent through the second dispensing component. This ensures the washing effect on the fabric while also enriching the user's choices regarding the laundry detergent.

[0076] The second dispensing component may further include a spray chamber 502 formed above the dispensing chamber 501. The spray chamber 502 is connected to the water inlet pipe 401. A spray plate 503 with multiple spray holes 504 is provided between the dispensing chamber 501 and the spray chamber 502. The spray chamber 502 is connected to the water inlet pipe 401. After the water in the water inlet pipe 401 enters the spray chamber 502, it will enter the dispensing chamber 501 below the spray chamber 502 by gravity through the spray holes on the spray plate 503. After the user manually dispenses the laundry detergent into the dispensing chamber 501, the water entering the dispensing chamber 501 below the spray chamber 502 by gravity will impact the laundry detergent, promoting the dissolution and mixing of the laundry detergent and water.

[0077] Furthermore, the second dispensing component may also include a dissolving chamber 505 communicating with the dispensing chamber 501. The dissolving chamber 505 is located below the dispensing chamber 501 and is connected to both the drain port 506 and the dispensing chamber 501. The dispensing chamber 501 is connected to the drain port 506 via the dissolving chamber 505. The liquid resulting from the mixture of laundry detergent and water in the dispensing chamber 501 flows into the dissolving chamber 505 below the dispensing chamber 501 under the influence of gravity. As the mixed liquid flows within the dissolving chamber 505, the laundry detergent in the mixed liquid continuously mixes with the water. After entering the washing container 101 through the drain port 506, the washing effect on the fabric to be treated is ensured.

[0078] According to a second embodiment provided in this application, a foam generating device is also provided for a washing device 1. The washing device 1 is provided with a washing container 101 for treating fabrics to be treated. The foam generating device includes a first dispensing component for dispensing foam liquid containing a laundry detergent into the washing container 101. The first dispensing component includes a first foaming chamber 201, a laundry detergent supply component, a water supply component, and a foaming component. The first foaming chamber 201 is provided with a first foam outlet 204. The laundry detergent supply component is used to provide laundry detergent into the first foaming chamber 201. The water supply component is used to provide pressurized water into the first foaming chamber 201. The foaming component is used to provide pressurized gas into the first foaming chamber 201 to mix the laundry detergent and water in the first foaming chamber 201 and form foam liquid. The first foaming chamber 201 is configured as a positive pressure chamber when the foam generating device is in use, and the foam liquid is discharged outward from the first foam outlet 204 with a jet pressure.

[0079] Through the above technical solution, the foam generating device is equipped with a first dispensing component. Through this component, the laundry detergent and water can be fully mixed in the first foaming chamber 201 to generate foam, forming a foam liquid which is then discharged from the first foam outlet 204. The laundry detergent can be used as a washing agent. When the foam generating device is applied to a washing machine 1 for washing clothes, the fabric to be treated is clothing. Compared to manually adding the laundry detergent during washing, the foam generating device directly dispenses the foam liquid into the washing container 101. This allows the foam liquid to directly contact the clothing, ensuring a good washing effect and reducing the time the laundry detergent takes to dissolve in water, thus improving the user experience. The laundry detergent supply component and water supply component can dispense a certain amount of laundry detergent and water into the first foaming chamber 201. The laundry detergent and water mix in the first foaming chamber 201 to form a laundry detergent-water mixture, which is then further foamed by the foaming component, increasing the foam generated in the first foaming chamber 201. The foaming component inside the first foaming chamber 201 can impact the laundry detergent water entering the first foaming chamber 201 with pressurized foaming gas, causing the laundry detergent water to further foam and form foam liquid. Furthermore, the foam liquid is discharged outward from the first foam outlet 204 with jet pressure. The jet pressure causes larger bubbles in the foam liquid to break up as it flows out of the first foam outlet 204, resulting in a finer foam liquid flowing out of the first foam outlet 204. The first foaming chamber 201 is configured as a positive pressure chamber when the foam generating device is in use, which also ensures the outflow of foam liquid.

[0080] The first dispensing component may further include a second foaming chamber 202 connected in series with the first foaming chamber 201 via a first foam outlet 204. The water supply component simultaneously supplies laundry detergent water to both the first and second foaming chambers 201 and 202. Here, "simultaneously" means that the laundry detergent supply component and the water supply component can supply both laundry detergent and water to the first foaming chamber 201 and the second foaming chamber 202. The second foaming chamber 202 may be located downstream of the first foaming chamber 201; downstream here refers to the downstream direction of the foam liquid flow path within the first foaming chamber 201. The second foaming chamber 202 increases the flow path of the foam liquid, allowing the laundry detergent and water to mix and dissolve thoroughly. Simultaneously, the increased flow path also allows larger bubbles to break up during flow, further increasing the fineness of the foam liquid. The water supply assembly simultaneously supplies laundry detergent water to the first foaming chamber 201 and the second foaming chamber 202. The water entering the second foaming chamber 202 can also increase the fluidity of the foam liquid, making it easier for the foam liquid to flow out from the foam outlet 211, and preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long, which would cause defoaming.

[0081] The second foaming chamber 202 can be configured as a positive pressure chamber when the foam generating device is in use. The second foaming chamber 202 is provided with a second foam outlet 205, from which the foam liquid is discharged outward with jet pressure. Specifically, the second foaming chamber 202 can be provided with the second foam outlet 205 on the side away from the first foam outlet 204, thus maximizing the flow path of the foam liquid within the first foaming chamber 201. The foam liquid is discharged outward from the second foam outlet 205 with jet pressure. The second foaming chamber 202 is configured as a positive pressure chamber when the foam generating device is in use, ensuring that the foam liquid can be discharged from the second foam outlet 205 with jet pressure. The jet pressure causes the larger foams in the foam liquid to break up as they flow out of the second foam outlet 205, resulting in a finer foam liquid flowing out of the second foam outlet 205.

[0082] The second foam outlet 205 and the first foam outlet 204 can be configured such that the flow path of the foam liquid from the first foam outlet 204 to the second foam outlet 205 in the second foaming chamber 202 is a bend. This bend ensures that the flow of the foam liquid is not too slow, while also reducing the flow speed to a certain extent. This allows larger bubbles in the foam liquid to break up, further increasing the fineness of the foam liquid.

[0083] The first dispensing component may further include a third foaming chamber 203 connected in series with the second foaming chamber 202 via a second foam outlet 205. The third foaming chamber 203 has a discharge port 211 connected to the first foaming chamber 201. The third foaming chamber 203 may be configured as a positive pressure chamber when the foam generating device is in use, with foam liquid being discharged outward from the discharge port 211 and having spray pressure. Preferably, the third foaming chamber 203 may be located downstream of the second foaming chamber 202 and connected in series with the second foam outlet 205, where downstream refers to the downstream of the foam liquid flow path within the second foaming chamber 202.

[0084] The third foaming chamber 203 is configured as a positive pressure chamber when the foam generating device is in use, ensuring that the foam liquid is discharged outward from the outlet 211 with spray pressure. This third foaming chamber 203 further increases the flow path of the foam liquid, allowing the laundry detergent and water to mix and dissolve thoroughly. Simultaneously, the increased flow path also allows larger bubbles to break down during flow, further increasing the fineness of the foam liquid. Furthermore, the spray pressure from the outlet 211 causes larger bubbles to break down as they flow out, resulting in a finer foam liquid and ensuring that the foam liquid generated within the foam generating device is discharged. Thus, the foam liquid formed in the first foaming chamber 201, after passing through the first outlet 204, the second outlet 205, and the outlet 211, becomes finer, ensuring a superior washing effect on clothes.

[0085] The foam generating device may further include a first partition chamber 206 that communicates with the first foaming chamber 201 and the second foaming chamber 202 respectively. The first partition chamber 206 forms a first spray nozzle 208 on the side facing the first foaming chamber 201 and a second spray nozzle 209 on the side facing the second foaming chamber 202. A water supply assembly simultaneously supplies laundry detergent water to the first foaming chamber 201 and the second foaming chamber 202 through the first spray nozzle 208 and the second spray nozzle 209. The water supply assembly simultaneously supplies water to the first foaming chamber 201 and the second foaming chamber 202 through the first partition chamber 206. The water entering the second foaming chamber 202 increases the fluidity of the foam liquid, making it easier for the foam liquid to flow out from the foam discharge port 211, and preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long, which could lead to defoaming. Meanwhile, the first partition chamber 206 can be set between the first foaming chamber 201 and the second foaming chamber 202, making the structure of the first partition chamber 206 more compact, and one first partition chamber 206 can supply water to the first foaming chamber 201 and the second foaming chamber 202 at the same time.

[0086] In some embodiments, multiple first spray nozzles 208 may be provided, with at least one first spray nozzle 208 spraying water toward the bottom of the first foaming chamber 201 to create turbulence in the water containing the laundry detergent within the first foaming chamber 201. When the water is sprayed to the bottom at a certain speed and angle, it carries the surrounding liquid along with it, forming a complex flow field. This turbulence not only helps the laundry detergent to be distributed more evenly within the foaming chamber but also increases its contact area with the foaming gas, thereby accelerating foam generation. Furthermore, the synergistic effect of multiple spray nozzles can improve water utilization efficiency, reduce unnecessary waste, and allow the laundry detergent to mix more thoroughly with the water for foaming. It also helps the laundry detergent water mix better with the foaming gas, thereby generating more foam.

[0087] In other embodiments, the foam generating device may further include a second partition chamber 207 communicating with the first foaming chamber 201. A water supply assembly supplies water to the first foaming chamber 201 through the second partition chamber 207. The second partition chamber 207 is located opposite the first partition chamber 206. A third spray nozzle 210 is formed on the side of the second partition chamber 207 facing the first foaming chamber 201, and the third spray nozzle 210 is positioned opposite to the first spray nozzle 208. In this way, the water sprayed from the first spray nozzle 208 and the water sprayed from the third spray nozzle 210 can collide and mix, resulting in a more complex flow pattern of the laundry detergent water within the foaming chamber, further enabling the laundry detergent water to generate more foam, and further enabling the foam liquid to generate more foam. Furthermore, the presence of the second partition chamber 207 can also buffer and regulate the water flow rate, ensuring the stability and continuity of the foaming process. The third spray nozzle 210 and the first spray nozzle 208 also enable the foam generating device to maintain efficient and stable performance even when processing large quantities of laundry detergent water.

[0088] A blocking structure can be provided inside the first foaming chamber 201. When water enters the first foaming chamber 201 from the first spray port 208, at least part of the water is sprayed onto the blocking structure. The presence of the blocking structure can also prevent water from directly impacting the cavity wall of the first foaming chamber 201, reducing energy loss and noise pollution.

[0089] The first foaming chamber 201 may be equipped with a rotatable turbulence structure to agitate the laundry detergent water. The turbulence structure can agitate the laundry detergent water, and the eddies and shear forces generated by the turbulence structure during rotation allow the laundry detergent water to come into more thorough contact with the foaming gas, increasing the mixing degree between the laundry detergent water and the foaming gas, thereby generating more foam.

[0090] The foaming assembly may include a first foaming element 301 disposed at the first foam outlet 204 and / or a second foaming element 302 disposed at the second foam outlet 205, for increasing the fineness of the foam in the foaming liquid. Specifically, the first foaming element 301 and / or the second foaming element 302 may be a mesh structure with a pore size of 50-500 mesh. The first foaming element 301 and / or the second foaming element 302 can filter out larger foam particles, which not only improves the fineness and stability of the foam but also enhances its durability and practicality. Simultaneously, when the foaming liquid passes through the second foaming element 302, the second foaming element 302 generates a certain resistance, further slowing down the flow rate of the foaming liquid and promoting its residence within the first foaming chamber 201, thus enabling the generation of more foam within the first foaming chamber 201.

[0091] The foaming assembly may include an air pump 304 connected to an external air source 303, a one-way valve 305, and a foaming element 306 disposed within a first foaming chamber 201. The foaming element 306 is connected to the external air source 303 via the one-way valve 305. Multiple foaming holes 307 are formed on the inner wall of the foaming element 306 for injecting pressurized foaming gas into the first foaming chamber 201. Gas from the external air source 303 is discharged through the foaming element 306 from the foaming holes 307, causing the liquid in the first foaming chamber 201 to foam. The gas discharged from the foaming holes 307 also agitates the liquid in the first foaming chamber 201, promoting the dissolution of the fabric treatment agent in the liquid. The external air source 303 can be connected to the foaming element 306 via the one-way valve 305 to prevent the liquid in the first foaming chamber 201 from flowing back into the external air source 303 through the foaming holes 307. The air pump 304 increases the gas volume within the foaming element 306, ensuring that the gas discharged from the foaming holes 307 carries a certain pressure, allowing the gas to fully agitate the laundry detergent water. Preferably, the foaming element 306 can be constructed as a hollow tube.

[0092] In some embodiments, the pore size of the foaming pores 307 can be 0.01 mm to 1 mm. Designing the pore size of the foaming pores 307 to be between 0.01 mm and 1 mm ensures that the foaming gas is injected into the first foaming chamber 201 at an appropriate pressure and flow rate, thereby generating an ideal foam effect. This design not only improves the efficiency and quality of foam generation but also enhances the versatility and applicability of the foam generating device. Simultaneously, the smaller foaming pores 307 also allow pressurized gas to be formed at the foaming port even at slower flow rates.

[0093] The pressurized gas supplied to the foam generating device can be ozone gas. Ozone has a sterilizing effect, and the ozone generating device can also provide additional oxidation and disinfection functions to the foam. Thus, the foam liquid produced by the first injection component is a foam liquid with a sterilizing effect, improving the hygiene and safety of the foam. This further ensures the washing effect on the fabrics to be treated. Besides ozone, in this application, the pressurized gas supplied to the foam generating device can also be other gases with sterilizing effects. This application limits the type of gas and ensures that it will not damage clothing or the human body.

[0094] The foaming component can be configured to provide pressurized foaming gas when pressurized laundry detergent and water are supplied to the first foaming chamber 201 by the laundry detergent supply and water supply components. This can improve the foaming efficiency of the foam generating device and reduce the time required to generate foam liquid.

[0095] The foam generating device also includes a second dispensing component for dispensing the laundry detergent into the washing container 101. The second dispensing component includes a dispensing chamber 501, which can be selectively connected to the outside of the washing equipment 1. The dispensing chamber 501 has a drain port 506 connected to the washing container 101. When the fabric to be treated is only lightly soiled or there is only a small amount of fabric to be treated, i.e., when the fabric does not require a strong washing effect, the user can also manually dispense the laundry detergent through the second dispensing component. This ensures the washing effect on the fabric while also enriching the user's choices regarding the laundry detergent.

[0096] The second dispensing component may further include a spray chamber 502 formed above the dispensing chamber 501. The spray chamber 502 is connected to the water inlet pipe 401. A spray plate 503 with multiple spray holes 504 is provided between the dispensing chamber 501 and the spray chamber 502. The spray chamber 502 is connected to the water inlet pipe 401. After the water in the water inlet pipe 401 enters the spray chamber 502, it will enter the dispensing chamber 501 below the spray chamber 502 by gravity through the spray holes on the spray plate 503. After the user manually dispenses the laundry detergent into the dispensing chamber 501, the water entering the dispensing chamber 501 below the spray chamber 502 by gravity will impact the laundry detergent, promoting the dissolution and mixing of the laundry detergent and water.

[0097] Furthermore, the second dispensing component may also include a dissolving chamber 505 communicating with the dispensing chamber 501. The dissolving chamber 505 is located below the dispensing chamber 501 and is connected to both the drain port 506 and the dispensing chamber 501. The dispensing chamber 501 is connected to the drain port 506 via the dissolving chamber 505. The liquid resulting from the mixture of laundry detergent and water in the dispensing chamber 501 flows into the dissolving chamber 505 below the dispensing chamber 501 under the influence of gravity. As the mixed liquid flows within the dissolving chamber 505, the laundry detergent in the mixed liquid continuously mixes with the water. After entering the washing container 101 through the drain port 506, the washing effect on the fabric to be treated is ensured.

[0098] In the foam generating devices of the two embodiments mentioned above, the foam generating device can have a housing. This housing can be the housing of the foam generating device itself, or it can be a housing formed by the installation environment. For example, when the foam generating device is installed inside the detergent dispenser of a laundry processing device, the inner wall of the detergent dispenser can form the housing of the foam generating device. In this case, the first foaming chamber 201, the second foaming chamber 202, and the third foaming chamber 203 mentioned above are all integrated within the housing. Furthermore, the shapes of the first foaming chamber 201, the second foaming chamber 202, and the third foaming chamber 203 can be configured to be spliced ​​together. This means that the first foaming chamber 201, the second foaming chamber 202, and the third foaming chamber 203 are not only simultaneously embedded within the housing, but the ability to splice together also makes the volume of the first dispensing component smaller. The first dispensing component within the housing is more compact, further reducing the volume and size of the housing. The foam generating device is smaller in size, making it easier to arrange and improving its versatility. In this application, the shapes of the first foaming cavity 201, the second foaming cavity 202, and the third foaming cavity 203 are not limited, as long as the shapes of the first foaming cavity 201, the second foaming cavity 202, and the third foaming cavity 203 are configured to be able to be spliced ​​together.

[0099] In the foam generating apparatus of the two embodiments mentioned above, the first dispensing component and the second dispensing component can both be integrated into the housing of the foam generating apparatus. In this way, the arrangement of the first dispensing component and the second dispensing component is more compact. Furthermore, the shapes of the dissolving chamber 505 and the dispensing chamber 501 are configured to be able to be spliced ​​with the shapes of the first foaming chamber 201, the second foaming chamber 202 and the third foaming chamber 203 after being spliced ​​together, further reducing the volume of the foam generating apparatus and facilitating the arrangement of the foam generating apparatus.

[0100] In the foam generating apparatus of the two embodiments mentioned above, the shape and size of the shell can be adapted to the washing equipment 1 to which the foam generating apparatus is applied. For example, when the installation space in the washing equipment 1 is large, the shell shape can be designed as a square or rectangular quadrilateral structure. When the installation space in the washing equipment 1 is small and there are other structures that need to be avoided, the shell shape and size can be adapted to the other structures that need to be avoided. Furthermore, the shape and size of the first foaming chamber 201, the second foaming chamber 202, the third foaming chamber 203, the dissolving chamber 505, and the spraying chamber 502 can be adapted to the arrangement of the various chambers and the shape and size of the shell, so as to make the arrangement of the first dispensing component and the second dispensing component more compact.

[0101] According to the third embodiment provided in this application, a clothing treatment agent dispensing device is provided, which includes a foam generating device of any of the above embodiments and has all the beneficial effects of the foam generating device, which will not be repeated here.

[0102] According to the fourth embodiment provided in this application, a washing device 1 is provided, including a washing container 101, an outer drum 102 and a foam generating device or a laundry detergent dispensing device as described above, and has all the beneficial effects of the foam generating device, which will not be described in detail here. The washing container 101 is connected to the outer drum 102.

[0103] The washing apparatus 1 may further include a heating tank 103 located below and communicating with the outer drum 102, and a heating element is provided inside the heating tank 103. The foam liquid entering the washing container 101 can enter the heating tank 103 and be heated by the heating element. The heated foam liquid will return to the washing container 101 due to its rotation. The heated foam liquid has a better cleaning effect, ensuring the washing effect on the fabrics to be treated. In some embodiments, the washing apparatus 1 may be a garment processing apparatus.

[0104] Washing equipment 1 can be a garment treatment device. When the foam generating device of this application is applied to the garment treatment device, the garment treatment agent can be detergent or fabric softener. Taking detergent as an example, the foam generating device can generate a foam liquid composed of detergent and water. Thus, when the garment treatment device washes clothes, the fine foam liquid generated by the foam generating device can directly enter the washing container 101 and adhere to the clothes. The foam liquid can directly contact the clothes, ensuring the washing effect, reducing the dissolution time of the garment treatment agent in water, and improving the user experience. At the same time, the foam liquid generated by the foam generating device of this application has finer and richer foam, further improving the washing effect on clothes.

[0105] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
