In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0054] In view of the problem that when using the existing washing machine, the user needs to manually put in the clothes treatment agent but it is difficult to ensure the washing effect of the fabric to be treated, the present application provides a foam generating device that is both a small volume structure and can ensure the washing effect of the fabric to be treated. Specifically, the present application provides a first dispensing component and a second dispensing component, while retaining the method that the user can manually put in the clothes treatment agent, and the first dispensing component ensures that the clothes treatment agent can be quantitatively put in, and further promotes the dissolution of the clothes treatment agent and generates foam liquid through the foaming component, thereby improving the cleaning effect of the clothes treatment agent and effectively ensuring the washing effect of the fabric to be treated.

[0055] According to the first embodiment provided by this application, Figures 1 to 3As shown, a foam generating device is provided, which is used 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, which is used to provide foam liquid with clothing treatment agent 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 foaming outlet 204; the liquid supply component is used to provide pressurized clothing treatment agent water to the first foaming chamber 201; the foaming component is used to provide pressurized gas into the first foaming chamber 201 to foam the clothing treatment agent water to form foam liquid; the first foaming chamber 201 is configured to be a positive pressure chamber when the foam generating device is in use, and the foam liquid is discharged outward from the first foaming outlet 204 with a spraying pressure.

[0056] Through the above technical solution, the foam generating device is provided with a first delivery component, through which the clothing treatment agent and water can be fully mixed in the first foaming chamber 201 and generate foam to form foam liquid and discharge outward from the first foam outlet 204. The clothing treatment agent here can be a detergent. When the foam generating device is applied to the washing device 1 for washing clothes, the fabric to be treated is clothes. Compared with the user manually delivering the clothing treatment agent when washing clothes, the foam liquid is directly delivered into the washing container 101 through the foam generating device. The foam liquid can directly contact with the clothes, ensure the washing effect of the clothes, reduce the time for the clothing treatment agent to dissolve in the water, ensure the washing effect of the fabric to be treated, and improve the user's experience. The liquid supply component can deliver a certain amount of clothing treatment agent water into the first foaming chamber 201. The clothing treatment agent water here refers to a mixed liquid of clothing treatment agent and water. When the pressurized clothing treatment agent water flows out of the liquid supply component, the pressure causes the clothing treatment agent water to generate foam. The liquid after the laundry treatment agent and water are mixed enters the first foaming chamber 201 and is further foamed by the foaming component, further increasing the foam generated in the first foaming chamber 201. The foaming component arranged in the first foaming chamber 201 can impact the laundry treatment agent water entering the first foaming chamber 201 with the foaming gas with pressure, so that the laundry treatment agent water is further foamed and forms a foam liquid. At the same time, the laundry treatment agent water is provided to the first foaming chamber 201, so that when entering the first foaming chamber 201 and in the process of foaming in the first foaming chamber 201, the laundry treatment agent can be fully dissolved in the water, so that the laundry treatment agent and the water can be fully mixed, which reduces the time for the laundry treatment agent to dissolve in the water and makes it easier for the laundry treatment agent water to form a foam liquid. Furthermore, the foam liquid is discharged outward from the first bubble outlet 204 and has a spray pressure. The spray pressure will cause the foam in the foam liquid to destroy larger foams when flowing out from the first bubble outlet 204, so that the foam liquid flowing out from the first bubble outlet 204 is 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 the foam liquid.

[0057] It should be noted that the two mentioned above and below are interconnected, which means that gas or liquid can flow between the two, and does not indicate or limit the connection relationship between the two. The foaming component mentioned above is used to provide pressurized gas into the first foaming chamber 201 to foam the laundry treatment agent water to form foam liquid, which means that the foaming component can provide pressurized gas into the first foaming chamber 201, and the gas causes the laundry treatment agent water to generate foam, so that the laundry treatment agent water can be turned into foam liquid, and the foam liquid is formed by mixing the laundry treatment agent and water.

[0058] The first dispensing component may also include a second foaming chamber 202 connected in series with the first foaming chamber 201 through the first foaming port 204, and the liquid supply component simultaneously provides clothing treatment agent water to the first foaming chamber 201 and the second foaming chamber 202. Here, "simultaneously" means that the liquid supply component can provide clothing treatment agent water to the first foaming chamber 201 and can also provide clothing treatment agent water to the second foaming chamber 202. The second foaming chamber 202 can be arranged downstream of the first foaming chamber 201, and the downstream here refers to the downstream of the foam liquid flow path in the first foaming chamber 201. The second foaming chamber 202 increases the flow path of the foam liquid, so that the clothing treatment agent and water can be fully mixed and dissolved. At the same time, the increase in the flow path of the foam liquid also allows larger bubbles to be broken when the foam liquid flows, further increasing the fineness of the foam liquid. The liquid supply component provides clothing treatment agent water to the first foaming chamber 201 and the second foaming chamber 202 at the same time. 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 bubble discharge port 211, thereby preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long and causing defoaming.

[0059] The second foaming chamber 202 can be configured as a positive pressure chamber when the foam generating device is in use, and the second foaming chamber 202 is provided with a second foaming port 205, and the foam liquid is discharged outwardly from the second foaming port 205 and has a spray pressure. Specifically, the second foaming chamber 202 can be provided with a second foaming port 205 on a side away from the first foaming port 204, so that the flow path of the foam liquid in the first foaming chamber 201 can be increased as much as possible. The foam liquid is discharged outwardly from the second foaming port 205 and has a spray 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 foaming port 205, and the foam liquid is discharged outwardly from the second foaming port 205 and has a spray pressure, and the spray pressure will cause the foam in the foam liquid to destroy the larger foam when it flows out from the second foaming port 205, so that the foam liquid flows out of the second foaming port 205 more delicate.

[0060] The second bubble outlet 205 and the first bubble outlet 204 can be configured such that the flow path of the foam liquid in the second foaming chamber 202 from the first bubble outlet 204 to the second bubble outlet 205 is a curved path. The curved path slows down the flow speed to a certain extent while ensuring that the flow of the foam liquid is not too slow, so that larger bubbles in the foam liquid can be broken, further increasing the fineness of the foam liquid.

[0061] The first dispensing component may also include a third foaming chamber 203 connected in series with the second foaming chamber 202 through a second foaming outlet 205, and the third foaming chamber 203 is provided with a foaming outlet 211 connected with 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, and the foam liquid is discharged outward from the foaming outlet 211 and has a spray pressure. Preferably, the third foaming chamber 203 may be arranged downstream of the second foaming chamber 202 and connected in series with the second foaming chamber 202 through the second foaming outlet 205, and the downstream here refers to the downstream of the foam liquid flow path in the second foaming chamber 202

[0062] The third foaming chamber 203 is configured to be a positive pressure chamber when the foam generating device is used, so that the foam liquid is discharged from the bubble outlet 211 and has a spray pressure. In this way, the third foaming chamber 203 further increases the flow path of the foam liquid, so that the clothing treatment agent and water can be fully mixed and dissolved. At the same time, the flow path of the foam liquid is increased, and the larger foam can be broken when the foam liquid flows, which further increases the fineness of the foam liquid. And the foam liquid is discharged from the bubble outlet 211 and has a spray pressure. The spray pressure will cause the foam in the foam liquid to destroy the larger foam when it flows out from the bubble outlet 211, so that the foam liquid flows out from the bubble outlet 211 more finely, and also ensures that the foam liquid generated in the foam generating device can be discharged. In this way, the foam liquid formed in the first foaming chamber 201 can make the foam liquid more fine after passing through the first bubble outlet 204, the second bubble outlet 205 and the bubble outlet 211, ensuring the washing effect on the clothes.

[0063] The foam generating device may further include a first partition chamber 206 which can be connected to the first foaming chamber 201 and the second foaming chamber 202 respectively. The first partition chamber 206 forms a first liquid spraying port 208 on the side facing the first foaming chamber 201; and forms a second liquid spraying port 209 on the side facing the second foaming chamber 202. The liquid supply component supplies clothing treatment agent water to the first foaming chamber 201 and the second foaming chamber 202 simultaneously through the first liquid spraying port 208 and the second liquid spraying port 209. The liquid supply component supplies clothing treatment agent water to the first foaming chamber 201 and the second foaming chamber 202 simultaneously 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 bubble discharge port 211, thereby preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long, resulting in defoaming. Meanwhile, the first partition chamber 206 can be disposed between the first foaming chamber 201 and the second foaming chamber 202 , so that the structure of the first partition chamber 206 is 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, the first liquid spraying port 208 may be provided with a plurality of first liquid spraying ports 208, and at least one first liquid spraying port 208 sprays laundry treatment agent water toward the bottom of the first foaming chamber 201, so that the laundry treatment agent water in the first foaming chamber 201 forms a turbulent flow. When the laundry treatment agent water is sprayed to the bottom at a certain speed and angle, it will drive the surrounding liquid to move together, forming a complex flow field. This turbulent flow not only helps the laundry treatment agent to be more evenly distributed in the foaming chamber, but also increases its contact area with the foaming gas, thereby accelerating the generation of foam. In addition, the synergistic effect of multiple liquid spraying ports can also improve the utilization efficiency of the laundry treatment agent water, reduce unnecessary waste, and make the laundry treatment agent and water more fully mixed and foamed, and also help the laundry treatment agent water to be better mixed with the foaming gas, thereby generating more foam.

[0065] In other embodiments, the foam generating device may further include a second partition chamber 207 connected to the first foaming chamber 201, the liquid supply assembly supplies clothing treatment agent water to the first foaming chamber 201 through the second partition chamber 207, the second partition chamber 207 is arranged on the opposite side of the first partition chamber 206, and the second partition chamber 207 forms a third liquid spraying port 210 on the side facing the first foaming chamber 201, and the third liquid spraying port 210 is arranged opposite to the first liquid spraying port 208. In this way, the clothing treatment agent water sprayed from the first liquid spraying port 208 and the clothing treatment agent water sprayed from the third liquid spraying port 210 can collide and mix with each other, so that the clothing treatment agent water forms a more complex flow pattern in the foaming chamber, further enabling the clothing treatment agent water to generate more foam, and further enabling the foam liquid to generate more foam. In addition, the existence of the second partition chamber 207 can also play a role in buffering and regulating the flow rate of the clothing treatment agent water, ensuring the stability and continuity of the foaming process. The third liquid spraying port 210 and the first liquid spraying port 208 also enable the foam generating device to maintain high efficiency and stable performance when processing a large amount of laundry treatment agent water.

[0066] A blocking structure may be provided in the first foaming chamber 201. When the laundry treatment agent water enters the first foaming chamber 201 from the first liquid spraying port 208, at least part of the laundry treatment agent water is sprayed onto the blocking structure. When the laundry treatment agent water enters the first foaming chamber 201 from the first liquid spraying port 208, at least part of the laundry treatment agent water is sprayed onto the blocking structure to cause splashing. The energy brought by the splashing can cause the laundry treatment agent water to generate foam, which helps to further increase the disturbance and mixing of the laundry treatment agent water, thereby generating more foam. The blocking structure here has a plate body with holes, so that the laundry treatment agent water sprayed from the first liquid spraying port 208 can contact the side plate body of the plate body to generate foam, and the laundry treatment agent water sprayed from the first liquid spraying port 208 can also impact each other through the holes to form foam. At the same time, the existence of the blocking structure can also prevent the laundry treatment agent 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 provided with a water inlet, which is connected to an external water source to replenish water during the process of foaming the clothing treatment agent water to form a foam liquid. In this way, during the process of foaming the clothing treatment agent water to form a foam liquid, water can be replenished into the first foaming chamber 201 through the water inlet and the external water source, which not only ensures the stable generation of the foam liquid, but also promotes the flow of the foam liquid, and avoids the foam liquid staying in the first foaming chamber 201, the second foaming chamber 202 and the third foaming chamber 203 for too long, resulting in defoaming. Replenishing water avoids the degradation of foam quality caused by insufficient water. The water replenishment function of the water inlet not only improves the efficiency and stability of foam generation, but also enables the foam generating device to work continuously and stably, extending the service life. In addition, the design of the water inlet can also be adjusted and optimized according to actual needs to meet the water quality and water quantity requirements of different application scenarios.

[0068] A rotatable flow disturbance structure may be provided in the first foaming chamber 201 to disturb the laundry treatment agent water. The vortex and shear force formed by the flow disturbance structure during the rotation process can make the laundry treatment agent water more fully contact with the foaming gas, increase the mixing degree of the laundry treatment agent water and the foaming gas, and thus generate more foam.

[0069] The foaming assembly may include a first foaming member 301 and / or a second foaming member 302 arranged at the first foam outlet 204 or the second foaming member 305, for increasing the fineness of the foam in the foam liquid. Specifically, the first foaming member 301 and / or the second foaming member 302 may be a mesh structure, and the aperture of the mesh structure may be 50 meshes-500 meshes. The first foaming member 301 and / or the second foaming member 302 may filter out larger foam, which not only improves the fineness and stability of the foam, but also enhances the durability and practicality of the foam. Meanwhile, when the foam liquid passes through the second foaming member 302, the second foaming member 302 may generate a certain resistance, further slow down the flow rate of the foam liquid, promote the stay of the foam liquid in the first foaming chamber 201, and enable more foam to be generated in the first foaming chamber 201.

[0070] The foaming component may include an external gas source 303 and an air pump 304 connected to the external gas source 303, a one-way valve 305, and a foaming member 306 disposed in the first foaming cavity 201, wherein the foaming member 306 is connected to the external gas source 303 through the one-way valve 305; a plurality of foaming holes 307 are provided on the inner wall of the foaming member 306 for injecting pressurized foaming gas into the first foaming cavity 201. The gas in the external gas source 303 is discharged from the foaming holes 307 via the foaming member 306, so as to cause the liquid in the first foaming cavity 201 to generate foam, and the gas discharged from the foaming holes 307 will stir the liquid in the first foaming cavity 201, so as to promote the dissolution of the laundry treatment agent in the liquid. The external gas source 303 may be connected to the foaming member 306 through the one-way valve 305, so as to prevent the liquid in the first foaming cavity 201 from flowing back to the external gas source 303 from the foaming holes 307. The air pump 304 can increase the gas in the foaming member 306, ensuring that the gas discharged from the foaming holes 307 can have a certain pressure, so that the gas can fully stir the laundry treatment agent water. Preferably, the foaming member 306 can be constructed as a hollow tube.

[0071] In some embodiments, the pore size of the foaming hole 307 may be 0.01 mm-1 mm. The pore size of the foaming hole 307 is designed to be between 0.01 mm and 1 mm, which can ensure that the foaming gas is injected into the first foaming chamber 201 at an appropriate pressure and flow rate, thereby generating an ideal foaming 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. At the same time, the smaller foaming hole 307 also allows the gas to form pressurized gas at the foaming port even when the flow rate is slow.

[0072] The pressurized gas provided to the foam generating device may be ozone gas. Ozone has a sterilization effect, and the ozone generating device can also provide additional oxidation and disinfection functions for the foam, so that the foam liquid generated by the first delivery component is a foam liquid with a sterilization effect, which improves the hygiene and safety of the foam. The washing effect on the fabric to be treated is further guaranteed. In addition to ozone, in the present application, the pressurized gas provided to the foam generating device may also be other gases that can have a sterilization effect. In this regard, the present application limits the type of gas, and it is also necessary to ensure that it does not damage clothing and the human body.

[0073] The foaming component can be configured to provide pressurized foaming gas when the liquid supply component provides pressurized laundry treatment agent water to the first foaming chamber 201. This can improve the foaming efficiency of the foam generating device and reduce the time for generating foam liquid.

[0074] The liquid supply assembly may include a water inlet pipeline 401, a storage chamber 402, and a delivery pump 403. A booster device 404 is provided on the water inlet pipeline 401. The water inlet pipeline 401 is communicated with the first foaming chamber 201 and the liquid storage chamber respectively. The storage chamber 402 is used to store clothing treatment agents. The delivery pump 403 is provided between the liquid storage chamber and the water inlet pipeline 401, and is used to suck the clothing treatment agents into the water inlet pipeline 401. By adjusting the opening and opening time of the delivery pump 403, the content of clothing treatment agents entering the first delivery assembly can be adjusted. The storage chamber 402 here can be provided with a plurality of storage chambers 402 to store different types of clothing treatment agents. Correspondingly, the delivery pump 403 can be provided with a plurality of storage chambers 402 corresponding to the number of storage chambers 402, and the delivery pump 403 corresponds to the storage chamber 402 one-to-one. In this way, for each type of clothing treatment agent, there is a corresponding delivery pump 403 for control. The water inlet pipe 401 can be communicated with the first partition chamber 206 and the second partition chamber 207 mentioned above, so that the water inlet pipe 401 can be communicated with the first foaming chamber 201. At the same time, the booster device 404 can ensure the spraying pressure of the laundry treatment agent water.

[0075] The foam generating device further includes a second delivery component, which is used to deliver the laundry treatment agent into the washing container 101. The second delivery component includes a delivery chamber 501, which can be selectively connected to the outside of the washing device 1, and the delivery chamber 501 is provided with a drain port 506 connected to the washing container 101. When the degree of dirtiness of the fabric to be treated is low or there are fewer fabrics to be treated, that is, when the fabric to be treated does not require a strong washing effect, the user can also manually deliver the laundry treatment agent through the second delivery component, which not only ensures the washing effect of the fabric to be treated, but also enriches the user's choice of delivering the laundry treatment agent.

[0076] The second delivery assembly may further include a spray chamber 502 formed above the delivery chamber 501, the spray chamber 502 is connected to the water inlet pipeline 401, and a spray plate 503 with a plurality of spray holes 504 is provided between the delivery chamber 501 and the spray chamber 502. The spray chamber 502 is connected to the water inlet pipeline 401, and after the water in the water inlet pipeline 401 enters the spray chamber 502, it will enter the delivery chamber 501 below the spray chamber 502 through the spray port on the spray plate 503 by gravity. After the user manually delivers the clothes treatment agent into the delivery chamber 501, the water that enters the delivery chamber 501 below the spray chamber 502 by gravity will impact the clothes treatment agent, thereby promoting the dissolution and mixing of the clothes treatment agent and water.

[0077] Furthermore, the second delivery assembly may further include a dissolving chamber 505 connected to the delivery chamber 501, the dissolving chamber 505 is arranged below the delivery chamber 501, the dissolving chamber 505 is respectively connected to the drain port 506 and the delivery chamber 501, and the delivery chamber 501 is connected to the drain port 506 through the dissolving chamber 505. The liquid after the clothes treatment agent and water are mixed in the delivery chamber 501 will flow into the dissolving chamber 505 below the delivery chamber 501 under the action of gravity. During the flow of the mixed liquid in the dissolving chamber 505, the clothes treatment agent in the mixed liquid will be continuously mixed with the water, and 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 the second embodiment provided by the present application, a foam generating device is also provided, which is used 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, which is used to provide foam liquid with clothing treatment agent into the washing container 101. The first dispensing component includes a first foaming chamber 201, a clothing treatment agent supply part, a water supply component and a foaming component: the first foaming chamber 201 is provided with a first foaming outlet 204; the clothing treatment agent supply part is used to provide clothing treatment agent to the first foaming chamber 201; the water supply component is used to provide pressurized water to the first foaming chamber 201; the foaming component is used to provide pressurized gas into the first foaming chamber 201 so that the clothing treatment agent and water in the first foaming chamber 201 are mixed and form foam liquid; the first foaming chamber 201 is configured to be a positive pressure chamber when the foam generating device is in use, and the foam liquid is discharged outward from the first foaming outlet 204 and has a spray pressure.

[0079] Through the above technical solution, the foam generating device is provided with a first delivery component, through which the clothing treatment agent and water can be fully mixed in the first foaming chamber 201 and generate foam to form foam liquid and be discharged from the first foam outlet 204. The clothing treatment agent here can be a detergent. When the foam generating device is applied to the washing device 1 for washing clothes, the fabric to be treated is clothes. Compared with the user manually delivering the clothing treatment agent when washing clothes, the foam liquid is directly delivered into the washing container 101 through the foam generating device. The foam liquid can directly contact the clothes, ensure the washing effect of the clothes, reduce the time for the clothing treatment agent to dissolve in water, ensure the washing effect of the fabric to be treated, and improve the user's experience. The clothing treatment agent supply part and the water supply component can deliver a certain amount of clothing treatment agent and water into the first foaming chamber 201. The clothing treatment agent and water enter the first foaming chamber 201 and mix to form clothing treatment agent water, which is further foamed by the foaming component to increase the foam generated in the first foaming chamber 201. The foaming component arranged in the first foaming chamber 201 can impact the laundry treatment agent water entering the first foaming chamber 201 through the foaming gas with pressure, so that the laundry treatment agent water further foams and forms foam liquid. Furthermore, the foam liquid is discharged outward from the first foam outlet 204 and has a spray pressure. The spray pressure will cause the foam in the foam liquid to break the larger foam when it flows out from the first foam outlet 204, so that the foam liquid flowing out from the first foam outlet 204 is more delicate. The first foaming chamber 201 is configured as a positive pressure chamber when the foam generating device is used, which also ensures the outflow of the foam liquid.

[0080] The first dispensing component may also include a second foaming chamber 202 connected in series with the first foaming chamber 201 through the first foaming port 204, and the water supply component simultaneously provides clothing treatment agent water to the first foaming chamber 201 and the second foaming chamber 202. At the same time here, it means that the clothing treatment agent supply part and the water supply component can provide clothing treatment agent and water to the first foaming chamber 201, and can also provide clothing treatment agent and water to the second foaming chamber 202. The second foaming chamber 202 can be arranged downstream of the first foaming chamber 201, and the downstream here refers to the downstream of the foam liquid flow path in the first foaming chamber 201. The second foaming chamber 202 increases the flow path of the foam liquid, so that the clothing treatment agent and water can be fully mixed and dissolved. At the same time, the flow path of the foam liquid is increased, and larger bubbles can be broken when the foam liquid flows, further increasing the fineness of the foam liquid. The water supply component provides clothing treatment agent water to the first foaming chamber 201 and the second foaming chamber 202 at the same time. 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 bubble discharge port 211, thereby preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long and causing defoaming.

[0081] The second foaming chamber 202 can be configured as a positive pressure chamber when the foam generating device is in use, and the second foaming chamber 202 is provided with a second foaming port 205, and the foam liquid is discharged outwardly from the second foaming port 205 and has a spray pressure. Specifically, the second foaming chamber 202 can be provided with a second foaming port 205 on a side away from the first foaming port 204, so that the flow path of the foam liquid in the first foaming chamber 201 can be increased as much as possible. The foam liquid is discharged outwardly from the second foaming port 205 and has a spray 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 foaming port 205, and the foam liquid is discharged outwardly from the second foaming port 205 and has a spray pressure, and the spray pressure will cause the foam in the foam liquid to destroy the larger foam when it flows out from the second foaming port 205, so that the foam liquid flows out of the second foaming port 205 more delicate.

[0082] The second bubble outlet 205 and the first bubble outlet 204 can be configured such that the flow path of the foam liquid in the second foaming chamber 202 from the first bubble outlet 204 to the second bubble outlet 205 is a curved path. The curved path slows down the flow speed to a certain extent while ensuring that the flow of the foam liquid is not too slow, so that larger bubbles in the foam liquid can be broken, further increasing the fineness of the foam liquid.

[0083] The first dispensing component may also include a third foaming chamber 203 connected in series with the second foaming chamber 202 through a second foaming outlet 205, and the third foaming chamber 203 is provided with a foaming outlet 211 connected with 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, and the foam liquid is discharged outward from the foaming outlet 211 and has a spray pressure. Preferably, the third foaming chamber 203 may be arranged downstream of the second foaming chamber 202 and connected in series with the second foaming chamber 202 through the second foaming outlet 205, and the downstream here refers to the downstream of the foam liquid flow path in the second foaming chamber 202

[0084] The third foaming chamber 203 is configured to be a positive pressure chamber when the foam generating device is used, so that the foam liquid is discharged from the bubble outlet 211 and has a spray pressure. In this way, the third foaming chamber 203 further increases the flow path of the foam liquid, so that the clothing treatment agent and water can be fully mixed and dissolved. At the same time, the flow path of the foam liquid is increased, and the larger foam can be broken when the foam liquid flows, which further increases the fineness of the foam liquid. And the foam liquid is discharged from the bubble outlet 211 and has a spray pressure. The spray pressure will cause the foam in the foam liquid to destroy the larger foam when it flows out from the bubble outlet 211, so that the foam liquid flows out from the bubble outlet 211 more finely, and also ensures that the foam liquid generated in the foam generating device can be discharged. In this way, the foam liquid formed in the first foaming chamber 201 can make the foam liquid more fine after passing through the first bubble outlet 204, the second bubble outlet 205 and the bubble outlet 211, ensuring the washing effect on the clothes.

[0085] The foam generating device may further include a first partition chamber 206 which can be connected to the first foaming chamber 201 and the second foaming chamber 202 respectively. The first partition chamber 206 forms a first liquid spraying port 208 on the side facing the first foaming chamber 201; and forms a second liquid spraying port 209 on the side facing the second foaming chamber 202. The water supply component supplies water of the laundry treatment agent to the first foaming chamber 201 and the second foaming chamber 202 simultaneously through the first liquid spraying port 208 and the second liquid spraying port 209. The water supply component supplies water to the first foaming chamber 201 and the second foaming chamber 202 simultaneously 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, thereby preventing the foam liquid from staying in the first foaming chamber 201 and the second foaming chamber 202 for too long, resulting in defoaming. Meanwhile, the first partition chamber 206 can be disposed between the first foaming chamber 201 and the second foaming chamber 202 , so that the structure of the first partition chamber 206 is 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, a plurality of first liquid spray ports 208 may be provided, and at least one first liquid spray port 208 sprays water toward the bottom of the first foaming chamber 201, so that the laundry treatment agent water in the first foaming chamber 201 forms a turbulent flow. When water is sprayed to the bottom at a certain speed and angle, it will drive the surrounding liquid to move together, forming a complex flow field. This turbulent flow not only helps the laundry treatment agent to be more evenly distributed in the foaming chamber, but also increases its contact area with the foaming gas, thereby accelerating the generation of foam. In addition, the synergistic effect of multiple liquid spray ports can also improve the utilization efficiency of water, reduce unnecessary waste, and make the laundry treatment agent and water more fully mixed and foamed, and also help the laundry treatment agent water to be better mixed with the foaming gas, thereby generating more foam.

[0087] In other embodiments, the foam generating device may further include a second partition chamber 207 connected to the first foaming chamber 201, the water supply assembly supplies water to the first foaming chamber 201 through the second partition chamber 207, the second partition chamber 207 is arranged on the opposite side of the first partition chamber 206, and the second partition chamber 207 forms a third liquid spraying port 210 on the side facing the first foaming chamber 201, and the third liquid spraying port 210 is arranged opposite to the first liquid spraying port 208. In this way, the water sprayed from the first liquid spraying port 208 and the water sprayed from the third liquid spraying port 210 can collide and mix with each other, so that the laundry treatment agent water forms a more complex flow pattern in the foaming chamber, further enabling the laundry treatment agent water to generate more foam, and further enabling the foam liquid to generate more foam. In addition, the existence of the second partition chamber 207 can also play a role in buffering and regulating the water flow, ensuring the stability and continuity of the foaming process. The third liquid spraying port 210 and the first liquid spraying port 208 also enable the foam generating device to maintain efficient and stable performance when processing a large amount of laundry treatment agent water.

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

[0089] A rotatable flow disturbance structure may be provided in the first foaming chamber 201 to disturb the laundry treatment agent water. The vortex and shear force formed by the flow disturbance structure during the rotation process can make the laundry treatment agent water more fully contact with the foaming gas, increase the mixing degree of the laundry treatment agent water and the foaming gas, and thus generate more foam.

[0090] The foaming assembly may include a first foaming member 301 and / or a second foaming member 302 arranged at the first foam outlet 204 or the second foaming member 305, for increasing the fineness of the foam in the foam liquid. Specifically, the first foaming member 301 and / or the second foaming member 302 may be a mesh structure, and the aperture of the mesh structure may be 50 meshes-500 meshes. The first foaming member 301 and / or the second foaming member 302 may filter out larger foam, which not only improves the fineness and stability of the foam, but also enhances the durability and practicality of the foam. Meanwhile, when the foam liquid passes through the second foaming member 302, the second foaming member 302 may generate a certain resistance, further slow down the flow rate of the foam liquid, promote the stay of the foam liquid in the first foaming chamber 201, and enable more foam to be generated in the first foaming chamber 201.

[0091] The foaming component may include an external gas source 303 and an air pump 304 connected to the external gas source 303, a one-way valve 305, and a foaming member 306 disposed in the first foaming cavity 201, wherein the foaming member 306 is connected to the external gas source 303 through the one-way valve 305; a plurality of foaming holes 307 are provided on the inner wall of the foaming member 306 for injecting pressurized foaming gas into the first foaming cavity 201. The gas in the external gas source 303 is discharged from the foaming holes 307 via the foaming member 306, so as to cause the liquid in the first foaming cavity 201 to generate foam, and the gas discharged from the foaming holes 307 will stir the liquid in the first foaming cavity 201, so as to promote the dissolution of the laundry treatment agent in the liquid. The external gas source 303 may be connected to the foaming member 306 through the one-way valve 305, so as to prevent the liquid in the first foaming cavity 201 from flowing back to the external gas source 303 from the foaming holes 307. The air pump 304 can increase the gas in the foaming member 306, ensuring that the gas discharged from the foaming holes 307 can have a certain pressure, so that the gas can fully stir the laundry treatment agent water. Preferably, the foaming member 306 can be constructed as a hollow tube.

[0092] In some embodiments, the pore size of the foaming hole 307 may be 0.01 mm-1 mm. The pore size of the foaming hole 307 is designed to be between 0.01 mm and 1 mm, which can ensure that the foaming gas is injected into the first foaming chamber 201 at an appropriate pressure and flow rate, thereby generating an ideal foaming 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. At the same time, the smaller foaming hole 307 also allows the gas to form pressurized gas at the foaming port even when the flow rate is slow.

[0093] The pressurized gas provided to the foam generating device may be ozone gas. Ozone has a sterilization effect, and the ozone generating device can also provide additional oxidation and disinfection functions for the foam, so that the foam liquid generated by the first delivery component is a foam liquid with a sterilization effect, which improves the hygiene and safety of the foam. The washing effect on the fabric to be treated is further guaranteed. In addition to ozone, in the present application, the pressurized gas provided to the foam generating device may also be other gases that can have a sterilization effect. In this regard, the present application limits the type of gas, and it is also necessary to ensure that it does not damage clothing and the human body.

[0094] The foaming assembly can be configured to provide pressurized foaming gas when the laundry treating agent supplying member and the water supplying assembly provide pressurized laundry treating agent and water to the first foaming chamber 201. This can improve the foaming efficiency of the foam generating device and reduce the time of generating foam liquid.

[0095] The foam generating device further includes a second delivery component, which is used to deliver the laundry treatment agent into the washing container 101. The second delivery component includes a delivery chamber 501, which can be selectively connected to the outside of the washing device 1, and the delivery chamber 501 is provided with a drain port 506 connected to the washing container 101. When the degree of dirtiness of the fabric to be treated is low or there are fewer fabrics to be treated, that is, when the fabric to be treated does not require a strong washing effect, the user can also manually deliver the laundry treatment agent through the second delivery component, which not only ensures the washing effect of the fabric to be treated, but also enriches the user's choice of delivering the laundry treatment agent.

[0096] The second delivery assembly may further include a spray chamber 502 formed above the delivery chamber 501, the spray chamber 502 is connected to the water inlet pipeline 401, and a spray plate 503 with a plurality of spray holes 504 is provided between the delivery chamber 501 and the spray chamber 502. The spray chamber 502 is connected to the water inlet pipeline 401, and after the water in the water inlet pipeline 401 enters the spray chamber 502, it will enter the delivery chamber 501 below the spray chamber 502 through the spray port on the spray plate 503 by gravity. After the user manually delivers the clothes treatment agent into the delivery chamber 501, the water that enters the delivery chamber 501 below the spray chamber 502 by gravity will impact the clothes treatment agent, thereby promoting the dissolution and mixing of the clothes treatment agent and water.

[0097] Furthermore, the second delivery assembly may further include a dissolving chamber 505 connected to the delivery chamber 501, the dissolving chamber 505 is arranged below the delivery chamber 501, the dissolving chamber 505 is respectively connected to the drain port 506 and the delivery chamber 501, and the delivery chamber 501 is connected to the drain port 506 through the dissolving chamber 505. The liquid after the clothes treatment agent and water are mixed in the delivery chamber 501 will flow into the dissolving chamber 505 below the delivery chamber 501 under the action of gravity. During the flow of the mixed liquid in the dissolving chamber 505, the clothes treatment agent in the mixed liquid will be continuously mixed with the water, and 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 devices can have a shell, and the shell here can be the shell of the foam generating device itself, or it can be a shell formed by the installation environment. For example, when the foam generating device is arranged in the detergent delivery box of the clothing processing equipment, the inner wall of the detergent delivery box can form the shell of the foam generating device. At this time, the first foaming chamber 201, the second foaming chamber 202 and the third foaming chamber 203 mentioned above are all integrated in the shell. Further, 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. In this way, the first foaming chamber 201, the second foaming chamber 202 and the third foaming chamber 203 are not only sunk in the shell at the same time, but the first foaming chamber 201, the second foaming chamber 202 and the third foaming chamber 203 that can be spliced ​​with each other also make the volume of the first delivery component smaller, and the first delivery component in the shell is more compact, further reducing the volume and size of the shell, and the volume of the foam generating device is smaller, which is more convenient for the arrangement of the foam generating device, and improves the versatility of the foam generating device. In the present 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 can be configured to be spliced ​​with each other.

[0099] In the foam generating devices of the two embodiments mentioned above, the first delivery component and the second delivery component can be integrated in the shell of the foam generating device, so that the arrangement of the first delivery component and the second delivery component is more compact, and the shapes of the dissolving chamber 505 and the delivery 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, thereby further reducing the volume of the foam generating device and facilitating the arrangement of the foam generating device.

[0100] In the foam generating devices of the two embodiments mentioned above, the shape and size of the shell can be adaptively designed according to the washing equipment 1 used for the foam generating device. For example, when the installation space in the washing equipment 1 is large, the shell shape can be designed to be a quadrilateral structure such as a square or rectangle. 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 adaptively designed according to the other structures to be avoided. Furthermore, the shapes and sizes 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 adaptively designed according to the setting positions between the various cavities and the shape and size of the shell, so as to make the arrangement of the first delivery component and the second delivery component more compact.

[0101] According to the third embodiment provided in the present application, a clothing treatment agent dispensing device is provided, which is equipped with a foam generating device of any of the above-mentioned embodiments and has all the beneficial effects of the above-mentioned foam generating devices, which will not be described in detail here.

[0102] According to the fourth embodiment provided in the present application, a washing device 1 is provided, including a washing container 101, an outer drum 102 and any one of the above-mentioned foam generating devices or the above-mentioned clothing treatment agent dispensing device, and having all the beneficial effects of the above-mentioned foam generating devices, which will not be repeated here. The washing container 101 is connected to the outer drum 102.

[0103] The washing device 1 may further include a heating tank 103 disposed below the outer drum 102 and in communication with the outer drum 102, wherein a heating element is disposed in 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, and the heated foam liquid will return to the washing container 101 due to the rotation of the washing container 101. The heated foam liquid has a better cleaning effect, thereby ensuring the washing effect of the fabric to be treated. In some embodiments, the washing device 1 may be a clothing treatment device.

[0104] The washing device 1 can be a clothing treatment device. In this way, when the foam generating device in the present application is applied to the clothing treatment device, the clothing treatment agent can be a detergent or a softener. Taking the clothing treatment agent as a detergent as an example, the foam generating device can be used to generate a foam liquid mixed with detergent and water. In this way, when the clothing treatment device washes the 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 to ensure the washing effect on the clothes, reduce the time for the clothing treatment agent to dissolve in water, and improve the user experience. At the same time, the foam in the foam liquid generated by the foam generating device in the present application is more delicate and rich, which further improves the washing effect on the clothes.
