Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning equipment, and specifically relates to a detergent adding device and a cleaning equipment having the device.

Background Art

[0002] With the improvement of people's living standards, various smart household appliances are widely applied to all aspects of people's lives. Taking washing machines as an example, as an essential household appliance in modern families, the functions of washing machines are becoming more and more diverse, and they can meet various needs of users as much as possible.

[0003] The conventional detergent adding method of washing machines is to add detergent into the washing tub by the impact of water flow. Since the water intake pressure is relatively large, the detergent is washed away into the washing tub within a short time after water intake, and efficient mixing of the detergent and water cannot be achieved. Furthermore, affected by the external temperature and the activity of the detergent, it takes a long time for the detergent to completely dissolve in water and for effective cleaning to start. Since the previous low-efficiency cleaning method also consumes corresponding energy and time, even if the clothes are washed for a long time, they cannot be cleaned cleanly, and the cleaning effect becomes poor.

[0004] Furthermore, when the water intake pressure is low, the detergent cannot be washed away cleanly, and a lot of detergent is likely to remain in the detergent case, which not only causes waste, but also adheres to the inner wall of the detergent case due to long-term accumulation, and bacteria may breed and have an adverse effect.

[0005] In view of these, the present invention has been proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The technical problem that this invention aims to solve is to overcome the shortcomings of the prior art and provide a detergent additive device. By adding a mixing device to the detergent additive device, water and detergent can be thoroughly mixed, improving the cleaning effect. Furthermore, by opening the liquid outlet through the movement of the valve assembly, the mixed liquid is sprayed so as to cover the object to be cleaned, thereby improving cleaning efficiency. [Means for solving the problem]

[0007] To solve the above technical problems, the basic concept of the technical idea adopted by the present invention is as follows: The detergent addition device is A housing with an internal cavity, A water intake port is provided on the aforementioned housing, which communicates with the aforementioned housing cavity and is used for water intake, It is located on the aforementioned housing, communicates with the aforementioned housing cavity, and has a liquid inlet for adding detergent, A mixing device provided on the aforementioned housing, at least a portion of which is located within the aforementioned housing cavity, for mixing water and detergent to form a mixed solution, It is mounted on the aforementioned housing, communicates with the aforementioned housing cavity, is located downstream of the aforementioned mixing device, and has a liquid outlet for introducing the mixed liquid, It comprises a valve assembly that is reciprocally movable within the aforementioned housing cavity and for opening and closing the aforementioned liquid outlet.

[0008] Furthermore, the aforementioned valve assembly, A valve body provided to be reciprocally movable within the aforementioned housing cavity, wherein one end of the valve body closest to the mixing device is provided with a containment cavity for containing the mixed liquid, An elastic component is provided at one end of the valve body away from the mixing device, one end of which is connected to the valve body, and the other end of which is connected to the inner wall of the housing, and the elastic component provides an action to move the valve body toward the mixing device.

[0009] Furthermore, position limiting portions are provided on the outer surface of the valve body and / or on the inner surface of the housing cavity to limit the position in which the valve body moves toward the mixing device.

[0010] Furthermore, the aforementioned mixing apparatus, A first conduit provided within the aforementioned housing cavity, wherein the axial direction of the first conduit is the same as the axial direction of the aforementioned housing, one end of the first conduit communicates with the water intake, and the other end communicates with the containment cavity, and the first conduit provides a force that causes the valve body to move away from the mixing device when the water intake increases within the containment cavity and pressure is generated. It comprises a second pipeline installed perpendicular to the aforementioned first pipeline, An access port is provided on the side wall of the aforementioned first pipeline, and the aforementioned second pipeline is located at the aforementioned access port position and communicates with the aforementioned first pipeline.

[0011] In the above configuration, during the water intake process, the formed mixed liquid constantly enters the containment cavity, and the pressure gradually increases, pushing and moving the valve body away from the mixing device. This opens the liquid outlet, and at the same time, under high pressure, the mixed liquid is ejected from the position of the liquid outlet, thereby achieving spray cleaning of the object to be cleaned and improving the cleaning effect.

[0012] By adjusting the water intake pressure, the speed and distance at which the valve body moves away from the mixing device can be adjusted, thereby allowing the opening size of the liquid outlet to be adjusted.

[0013] Furthermore, at one end of the aforementioned first pipeline that communicates with the water intake, the diameter of the pipeline gradually decreases along the direction of water flow, forming a venturi structure. The point where the first and second pipelines connect is located downstream of the aforementioned venturi structure.

[0014] Furthermore, the pipeline is further equipped with flow guide ribs, the aforementioned flow guide ribs are provided on the outer surface of the first pipeline and protrude from the outer surface of the first pipeline, and the aforementioned flow guide ribs are installed at intervals along the circumferential direction of the first pipeline. The axial direction of the aforementioned flow guide rib and the axial direction of the aforementioned first pipe are at an angle.

[0015] In the above configuration, by installing guide ribs on the outer surface of the first pipeline, the guiding action of the guide ribs on the water flow is utilized to change the direction of the original water flow, exerting a turbulent effect and resulting in a more uniform mixing of the water flow and detergent.

[0016] Furthermore, there is a gap between the outer surface of the aforementioned first conduit and the inner surface of the housing cavity, The diameter of the outer contour of the aforementioned first conduit is smaller than the diameter of the aforementioned containment cavity.

[0017] In the above configuration, there is a gap between the outer surface of the first conduit and the inner surface of the housing cavity. This is to allow some of the water to pass through from the outside of the first conduit, thereby using the flow guide ribs to create turbulence in the water flow and improve the degree of mixing between the water and the detergent.

[0018] The diameter of the outer contour of the first conduit is smaller than the diameter of the aforementioned containment cavity. This is to allow water passing from outside the first conduit to also flow into the containment cavity, which not only creates turbulence for the water and detergent flowing through the first conduit, but also increases the force that pushes the valve body away from the mixing device, thereby increasing the distance the valve body travels and thus allowing the liquid outlet to open wider.

[0019] Furthermore, the aforementioned second pipeline is connected to the aforementioned liquid inlet, Alternatively, an assembly port is provided on the aforementioned housing, and the aforementioned second conduit is provided at the location of the aforementioned assembly port, forming the aforementioned liquid inlet.

[0020] In the above configuration, the installation of a venturi structure generates a venturi effect when the water flow passes through the venturi structure. Under low pressure, the detergent is drawn up into the first pipe via a siphon action through the second pipe, thereby enabling automatic detergent dispensing.

[0021] Furthermore, the aforementioned liquid discharge port is provided on the bottom wall of the aforementioned housing, is located at one end close to the mixing device below the valve body, and is arranged along the axial direction of the housing.

[0022] Preferably, a through-hole is provided on the bottom wall of the aforementioned accommodation cavity, and the aforementioned through-hole communicates with the aforementioned liquid discharge port through the housing cavity.

[0023] In the above form, the liquid discharge port is provided at one end close to the mixing device below the valve body, and the valve body can open the liquid discharge port by moving only a short distance, facilitating the discharge of the liquid.

[0024] Also, by providing a through-hole on the bottom wall of the accommodation cavity, the outflow of the mixed liquid flowing into the accommodation cavity is facilitated. Further, when the pressure decreases and the valve body closes the liquid discharge port, the water or mixed liquid remaining in the device can flow out from the through-hole and further from the liquid discharge port, effectively reducing the residue and avoiding waste.

[0025] A cleaning facility having a detergent addition device as described above, wherein the aforementioned cleaning facility includes A liquid storage tank that communicates with the liquid inlet of the aforementioned detergent addition device and provides a liquid storage tank for supplying detergent, A cleaning chamber, wherein the liquid discharge port of the aforementioned detergent addition device is installed above the aforementioned cleaning chamber, and a cleaning chamber for realizing spray cleaning.

[0026] By adopting the above technical idea, the present invention has the following beneficial effects compared with the prior art.

Effects of the Invention

[0027] In the present invention, by adding a mixing device in the detergent addition device, water and detergent can be sufficiently mixed, improving the cleaning effect.

[0028] In the water intake process, the formed mixed liquid continuously enters the containment cavity, and the pressure gradually increases, pushing and moving the valve body away from the mixing device. This opens the liquid outlet, and simultaneously, under high pressure, the mixed liquid is ejected from the position of the liquid outlet, so that the mixed liquid is ejected to cover the object to be cleaned, thereby improving cleaning efficiency.

[0029] In this invention, by installing flow guide ribs on the outer surface of the first pipeline, the guiding action of the flow guide ribs on the water flow is utilized to change the direction of the original water flow, exert a turbulent effect, and mix the water flow and detergent more uniformly.

[0030] In this invention, a gap is provided between the outer surface of the first conduit and the inner surface of the housing cavity. This is to allow some of the water to pass through from the outside of the first conduit, thereby creating turbulence in the water flow using the flow guide ribs and improving the degree of mixing between the water and the detergent.

[0031] In this invention, the diameter of the outer contour of the first conduit is set to be smaller than the diameter of the aforementioned containment cavity. This is to allow water passing from outside the first conduit to also flow into the containment cavity, which not only creates turbulence for the water and detergent flowing through the first conduit, but also increases the force that pushes and moves the valve body away from the mixing device, thereby increasing the distance the valve body moves and, consequently, allowing the liquid outlet to open wider.

[0032] In this invention, by installing a venturi structure on the first pipeline, a venturi effect is generated when the water flow passes through the venturi structure. Under low pressure, detergent is drawn up into the first pipeline via a siphon action through the second pipeline, thereby enabling automatic detergent dispensing.

[0033] In this invention, the liquid outlet is provided at one end of the valve body, closer to the mixing device below it, allowing the liquid outlet to be opened by moving the valve body only a short distance, thus facilitating liquid discharge.

[0034] The present invention provides a through-hole in the bottom wall of the containment cavity, which facilitates the outflow of the mixed liquid that has flowed into the containment cavity. Furthermore, when the pressure decreases and the valve body closes the liquid outlet, any water or mixed liquid remaining in the device can be discharged through the through-hole and also through the liquid outlet, effectively reducing residue and avoiding waste.

[0035] The cleaning equipment provided by the present invention has the above-mentioned detergent addition device and is characterized by excellent cleaning effect and high efficiency.

[0036] Specific embodiments of the present invention will be described in more detail below with reference to the drawings. [Brief explanation of the drawing]

For example, the connection may be removable, mechanical, or electrical. Furthermore, the connection may be direct or indirect, mediated through an intermediate intermediary. Those skilled in the art will be able to understand the specific meaning of these terms in this invention depending on the specific circumstances.

[0041] As shown in Figures 1 to 5, the present invention provides a detergent additive device, which comprises a housing 100, the housing 100 comprising a first housing 110 and a second housing 130. A first housing cavity 120 is formed in the first housing 110, and a second housing cavity 140 is formed in the second housing 130. An intake port 200 and a mixing device 300 are provided on the first housing 110, the intake port 200 comprising a first intake port 210 and a second intake port 220, and the mixing device 300 comprising a first pipeline 310 and a second pipeline 320. A venturi structure 311 is provided on the first pipeline 310, and flow guide ribs 312 are provided on the outer surface of the first pipeline 310. A liquid outlet 600 and a valve assembly 500 are provided on the aforementioned second housing 130. The valve assembly 500 comprises a valve body 510 and an elastic component 520, and a housing cavity 511 and a through hole are provided on the valve body 510.

[0042] As one embodiment, the present invention provides a detergent additive device. As shown in Figures 1 to 3, the aforementioned detergent additive device comprises a housing 100, and a housing cavity is formed inside the housing 100.

[0043] The aforementioned housing 100 comprises a first housing 110 and a second housing 130, with a first housing cavity 120 formed within the first housing 110 and a second housing cavity 140 formed within the second housing 130.

[0044] The structures of the first housing 110 and the second housing 130 described above are both closed at one end and open at the other end, and the first housing 110 and the second housing 130 are detachably connected to each other via the open end.

[0045] In this embodiment, the housing 100 is divided into a first housing 110 and a second housing 130, and the first housing 110 and the second housing 130 are detachably connected, making it easy to install, remove, and maintain the device.

[0046] As shown in Figure 3, the diameter of the opening end of the second housing 130 is larger than the diameter of the opening end of the first housing 110. As a result, the opening end of the first housing 110 can be inserted into the opening end of the second housing 130, and some of the structures of the two overlap.

[0047] There are various methods for achieving a detachable connection. For example, fasteners and / or grooves may be installed at the open ends of the first housing 110 and / or the second housing 130, and the fasteners and grooves may be assembled in correspondence to achieve a detachable connection between the first housing 110 and the second housing 130. Alternatively, a male screw may be installed at the open end of the first housing 110 and a female screw at the open end of the second housing 130, and a detachable connection between the first housing 110 and the second housing 130 may be achieved by screw threading. These are not the only methods, and the invention is not limited to these.

[0048] At least two water intake ports 200 are provided on the aforementioned first housing 110, and these water intake ports 200 communicate with the aforementioned first housing cavity 120 and are for drawing water into the first housing cavity 120.

[0049] Each water intake port 200 is provided with a corresponding water intake valve for opening and closing the aforementioned water intake port 200.

[0050] The aforementioned water intake 200 comprises a first water intake 210 and a second water intake 220. The first water intake 210 is a hot water intake 200, and a corresponding hot water valve is provided. The second water intake 220 is a cold water intake 200, and a corresponding cold water valve is provided.

[0051] In this embodiment, users can selectively open either the hot water intake 200 or the cold water intake 200 according to the needs of users in different regions, thereby meeting various needs and improving the user experience.

[0052] As shown in Figure 3, the aforementioned first water intake 210 and second water intake 220 are provided at the closed end of the aforementioned first housing 110, arranged along the axial direction of the first housing 110, and the upper side of the closed end of the first housing 110 is installed in a stepped structure, so that the horizontal plane on which the first water intake 210 is located is lower than the horizontal plane on which the second water intake 220 is located.

[0053] At the same time, a shut-off section 230 is provided below the second water intake 220, and preferably, the aforementioned shut-off section 230 has a plate-like structure.

[0054] The longitudinal extension direction of the aforementioned blocking section 230 is the same as the axial direction of the first housing 110. One end of the aforementioned blocking section 230 is connected to the vertical structure of the stepped structure, and the other end extends toward the open end of the first housing 110. Both ends of the aforementioned blocking section 230 in the width direction are connected to the inner walls of the first housing cavity 120. As a result, the water flow entering from the second intake port 220 flows rapidly downstream under the blocking action of the blocking section 230 and does not interfere with the water flow entering from the first intake port 210. This allows the intake pressure to be maintained and the water to flow more quickly downstream.

[0055] It should be explained that the number, location, and direction of the water intake 200 can all be determined according to the actual situation, thereby meeting various water intake needs.

[0056] A liquid inlet 400 for adding detergent is provided on the aforementioned first housing 110, and is in communication with the aforementioned first housing cavity 120.

[0057] A mixing device 300 is provided near the open end on the aforementioned first housing 110. At least a portion of the aforementioned mixing device 300 is located inside the cavity 120 of the first housing and is for mixing water and detergent to form a mixed liquid.

[0058] A liquid outlet 600 is provided on the aforementioned second housing 130. The aforementioned liquid outlet 600 communicates with the aforementioned cavity 140 of the second housing and is for introducing a mixed liquid.

[0059] The system further includes a valve assembly 500 that is reciprocally movable within the aforementioned second housing cavity 140 and for opening and closing the aforementioned liquid outlet 600.

[0060] The aforementioned valve assembly 500 comprises a valve body 510 and an elastic component 520.

[0061] The aforementioned valve body 510 is provided so as to be reciprocally movable within the aforementioned second housing cavity 140 and is located at the open end of the second housing 130.

[0062] A containment cavity 511 for containing the mixed liquid is provided near the opening end of the second housing 130 of the aforementioned valve body 510.

[0063] The aforementioned elastic component 520 is provided at the closed end of the aforementioned second housing 130, with one end of the elastic component 520 connected to the valve body 510 and the other end connected to the inner wall of the second housing 130, and is intended to provide a force for the valve body 510 to move toward the mixing device 300.

[0064] The aforementioned elastic component 520 is a spring.

[0065] As shown in Figure 3, a valve stem is provided at one end of the valve body 510 closest to the elastic component 520. The diameter of the outer contour of the valve stem is smaller than the diameter of the outer contour of the housing cavity 511, and one end of the elastic component 520 is connected to the valve stem.

[0066] The diameter of the closed end of the aforementioned second housing cavity 140 is smaller than the diameter of the open end, the diameter change position is located at the connection position between the valve stem and the elastic component 520, and the second housing 130 at the diameter change position has a conical shape.

[0067] The elastic component 520 is provided at the closed end where the diameter of the second housing 130 decreases. By matching the diameter of the internal cavity at the closed end to the diameter of the elastic component 520, it is ensured that the elastic component 520 can undergo elastic deformation, thereby increasing the stability of the elastic component 520 and preventing the valve body 510 from being unable to reciprocate normally due to the vibration of the elastic component 520.

[0068] A position limiting portion 700 is provided on the outer surface of the valve body 510 and / or on the inner surface of the housing cavity to limit the position in which the valve body 510 moves toward the mixing device 300.

[0069] As shown in Figure 3, when the opening end of the first housing 110 is inserted into the opening end of the second housing 130, and some of the structures of both overlap, and the valve body 510 moves to a limited position toward the mixing device 300, the liquid discharge end of the aforementioned mixing device 300 and the liquid injection end of the aforementioned housing cavity 511 are in the same vertical plane, or some of their structures overlap.

[0070] Since the diameter of the open end of the first housing cavity 120 is larger than the diameter of the closed end, the inner wall of the first housing cavity 120 forms a step where the diameter changes. This step is the position limiting portion 700, and the valve body 510 is provided at one end of the housing cavity 511 and abuts against the position limiting portion 700.

[0071] It should be explained that the position limiting section 700 may be installed on the outer surface of the valve body 510, as long as it can limit the position in which the valve body 510 moves toward the mixing device 300.

[0072] As shown in Figure 2, the aforementioned liquid outlet 600 is located on the bottom wall of the second housing 130, near the opening end of the second housing 130, and below the valve body 510.

[0073] In this embodiment, the liquid outlet 600 is installed near the open end of the second housing 130, and the liquid outlet 600 can be opened by the valve body 510 moving only a short distance, making it easy to discharge the liquid.

[0074] Multiple sets of the aforementioned liquid outlets 600 are provided, and these sets of liquid outlets 600 are installed on the bottom wall of the second housing 130 at intervals along the circumferential direction. Each set of liquid outlets 600 is evenly arranged along the axial direction of the second housing 130, and as a result, the liquid discharge direction of the liquid outlets 600 is different, increasing the covered area.

[0075] A through-hole is provided in the bottom wall of the aforementioned housing cavity 511, and this through-hole communicates with the aforementioned liquid outlet via the second housing cavity 140.

[0076] In this embodiment, by providing through holes on the bottom wall of the containment cavity 511, the mixed liquid that has flowed into the containment cavity 511 can be easily discharged. Furthermore, when the pressure decreases and the valve body 510 closes the liquid outlet 600, any water or mixed liquid remaining in the device can be discharged through the through holes and also through the liquid outlet 600, effectively reducing residue and avoiding waste.

[0077] It should be noted that the dimensions of the through-hole are small and have little effect on the magnitude of the pressure generated when the mixed liquid flows into the containment cavity 511.

[0078] As shown in Figures 4 and 5, the aforementioned mixing apparatus 300 includes a first pipeline 310 and a second pipeline 320.

[0079] The aforementioned first pipeline 310 is provided within the aforementioned first housing cavity 120, and the axial direction of the aforementioned first pipeline 310 is the same as the axial direction of the aforementioned first housing 110. One end of the aforementioned first pipeline 310 communicates with the water intake 200, and the other end communicates with the aforementioned housing cavity 511. When the water intake increases in the aforementioned housing cavity 511, pressure is generated, providing a force that causes the valve body 510 to move away from the mixing device 300.

[0080] The aforementioned second pipeline 320 is installed perpendicular to the aforementioned first pipeline 310.

[0081] An access port is provided on the side wall of the aforementioned first conduit 310, and the aforementioned second conduit 320 is provided at the location of the aforementioned access port and communicates with the aforementioned first conduit 310.

[0082] In this embodiment, during the water intake process, the formed mixed liquid continuously enters the containment cavity 511, and the pressure gradually increases, pushing and moving the valve body 510 away from the mixing device 300. This opens the liquid outlet 600, and at the same time, under high pressure, the mixed liquid is sprayed from the position of the liquid outlet 600, thereby achieving spray cleaning of the object to be cleaned and improving the cleaning effect.

[0083] One end of the aforementioned first pipeline 310 that communicates with the water intake 200 gradually reduces in diameter along the direction of water flow, forming a venturi structure 311.

[0084] Preferably, the portion where the diameter gradually decreases takes on a conical shape.

[0085] The point where the first pipeline 310 and the second pipeline 320 connect is located downstream of the Venturi structure 311.

[0086] Preferably, one end of the second pipe 320 that communicates with the first pipe 310 has an inverted conical shape, which causes an acceleration effect when the detergent passes through this position, contributing to improving the degree of mixing between the detergent and water.

[0087] In this embodiment, the installation of the Venturi structure 311 generates a Venturi effect when the water flow passes through the Venturi structure 311. Under low pressure, the detergent is drawn up into the first pipe 310 via the second pipe 320 by siphon action, thereby enabling automatic detergent dispensing.

[0088] The surface of the pipe at the intake end of the aforementioned first pipeline 310 transitions smoothly, reducing resistance as the water flow passes through.

[0089] The pipeline is further provided with flow guide ribs 312, which are provided on the outer surface of the first pipeline 310 and protrude from the outer surface of the first pipeline 310, and the flow guide ribs 312 are installed at intervals along the circumferential direction of the first pipeline 310.

[0090] The axial direction of the aforementioned flow guide rib 312 and the axial direction of the aforementioned first pipe 310 are at an angle.

[0091] As shown in Figure 4, the aforementioned flow guide rib 312 comprises a first body and a second body. The first body is linear in shape, and its axial direction is the same as the axial direction of the first pipe 310. The second body is arc-shaped, connected to the first body, and has an angle between its axial direction and the axial direction of the first pipe 310.

[0092] In this embodiment, by installing the flow guide ribs 312 on the outer surface of the first pipe 310, the guiding action of the flow guide ribs 312 on the water flow is utilized to change the direction of the original water flow, exert a turbulent effect, and mix the water flow and detergent more uniformly.

[0093] It should be explained that the flow guide rib 312 may have a shape such as a wave, as long as it can exert both flow guide and turbulent effects on the water flow.

[0094] There is a gap between the outer surface of the aforementioned first conduit 310 and the inner surface of the housing cavity.

[0095] In this embodiment, there is a gap between the outer surface of the first conduit 310 and the inner surface of the housing cavity. This is to allow some of the water to pass through from the outside of the first conduit 310, thereby using the flow guide rib 312 to create turbulence in the water flow and improve the degree of mixing between the water and the detergent.

[0096] The diameter of the outer contour of the aforementioned first conduit 310 is smaller than the diameter of the aforementioned containment cavity 511.

[0097] In this embodiment, the diameter of the outer contour of the first conduit 310 is smaller than the diameter of the aforementioned containment cavity 511. This is to allow water passing from outside the first conduit 310 to flow into the containment cavity 511, which not only creates turbulence for the water and detergent flowing through the first conduit 310, but also increases the force that pushes the valve body 510 away from the mixing device 300, thereby increasing the distance the valve body 510 travels and allowing the liquid outlet 600 to open wider.

[0098] The aforementioned second conduit 320 communicates with the aforementioned liquid inlet 400, or an assembly port is provided on the aforementioned housing 100, and the aforementioned second conduit 320 is provided at the location of the aforementioned assembly port, forming the aforementioned liquid inlet 400.

[0099] In this embodiment, when the liquid injection end of the second pipeline 320 communicates with the aforementioned liquid inlet 400, the detergent enters from the liquid inlet 400 and enters the first pipeline 310 via the second pipeline 320, thereby achieving mixing of water and detergent.

[0100] Alternatively, the aforementioned assembly port and the aforementioned liquid inlet 400 have the same structure, the aforementioned second conduit 320 is attached to the aforementioned assembly port position and protrudes from the upper surface of the second housing 130, and the detergent enters the first conduit 310 directly from the second conduit 320, thereby achieving mixing of water and detergent.

[0101] As one embodiment, the present invention provides a cleaning system having a detergent addition device as described above.

[0102] The aforementioned cleaning equipment is equipped with a liquid storage tank, which is connected to the liquid inlet 400 of the aforementioned detergent additive device and is for supplying detergent.

[0103] The aforementioned liquid storage tank is equipped with multiple storage chambers for storing detergents, fabric softeners, etc. Each storage chamber has a corresponding inlet, and these inlets can be selectively opened and closed, and each inlet can communicate with the liquid inlet 400.

[0104] The system is further equipped with a cleaning chamber, and the liquid outlet 600 of the aforementioned detergent additive device is located above the cleaning chamber to enable spray cleaning.

[0105] If we take a pulsator-type washing machine as an example of the washing equipment, the aforementioned washing chamber is, in other words, the washing tank.

[0106] The aforementioned pulsator-type washing machine has a base. The aforementioned detergent dispenser is mounted on the aforementioned base, and the liquid outlet 600 is installed above the washing tank to enable spray washing of clothes.

[0107] In response to this, a mounting portion 800 is provided on the housing 100 of the detergent additive device for mounting the detergent additive device onto the aforementioned base.

[0108] in particular, When the washing machine is started and a washing program is selected, the water intake valve opens and water enters the first housing cavity 120 from the water intake 200. Some of the water flows into the first conduit 310 and, as it passes through the venturi structure 311, creates a venturi effect. Under low pressure, the detergent is drawn up into the first conduit 310 via the second conduit 320 by siphon action, achieving mixing of water and detergent. The remaining water passes from the outside of the first conduit 310 and, under the flow guidance action of the flow guide rib 312, flows to the end of the first conduit 310, creating turbulence in the mixture and further improving the degree of mixing.

[0109] The formed mixture continuously flows into the containment cavity 511, and the pressure gradually increases, pushing and moving the valve body 510 away from the mixing device 300, thereby opening the liquid outlet 600. At the same time, under high pressure, the mixture is sprayed from the liquid outlet 600 into the washing tank, and simultaneously, a small amount of the mixture flows out through a through-hole in the bottom wall of the containment cavity 511 and enters the washing tank through the liquid outlet 600, achieving spray washing of the clothes and improving the washing effect.

[0110] Once water intake is complete, the pressure gradually decreases and disappears, causing the valve body 510 to lose its force and move towards the mixing device 300, closing the liquid outlet 600. At this time, any water or mixture remaining in the device can be discharged through the through-hole and further into the washing tank via the liquid outlet 600, effectively reducing residue and avoiding waste.

[0111] It should be explained that the washing equipment may include drum-type washing machines, dishwashers, etc.

[0112] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. The present invention has already been disclosed as described above by preferred embodiments, but this is not intended to limit the present invention. Those skilled in the art can make equivalent embodiments by making minor changes or modifications to the technical content shown above, without departing from the technical spirit of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the technical spirit of the present invention, still remain within the scope of the present invention.
