Description

Technical Field

[0001] The invention belongs to the field of clothing cleaning, and in particular relates to a placing device and a wall-mounted washing machine. Background Art

[0002] The clothing treatment device is a frequently used household appliance. The clothing treatment device is provided with a dispensing device, which mainly includes a water box connected to the water inlet pipeline of the clothing treatment device and a dispenser box contained in the water box. The dispenser box is usually arranged to be retractable in the water box, so that the user can pull out the dispenser box from the water box and add detergent, and / or softener, and / or disinfectant and other additives into the box. After the clothing treatment device starts to take in water, the additives in the liquid storage box are sucked by the liquid pumping device and dispensed into the water path of the water box. The water in the water inlet pipeline can first enter the water supply water path of the water box and mix with the additives to form a mixed liquid, and then be added to the interior of the clothing treatment device to wash the clothes.

[0003] In the existing dispensing device, a push-up device is usually installed on the dispenser box to lock the dispenser box on the water box. When additives are needed, the dispenser box is popped out from the water box by triggering the button of the push-up device. The problem is that the push-up device needs to compress its own spring when locking the dispenser box; the length of time the spring is in the stretched state when the detergent is changed is very long relative to the length of time it is in the compressed state, so that the spring is in a compressed state for a long time, causing the spring to easily suffer from elastic fatigue, resulting in the push-up device being unable to effectively lock the dispenser box, resulting in the dispenser box accidentally detaching and being unable to be used normally, affecting normal use.

[0004] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1-9 As shown, in an embodiment of the present invention, a dispensing device 1 is introduced, including a water box 2, which has a flow channel for water to flow inside; a distributor box 3, which is drawable and arranged in the accommodating cavity of the water box 2, and is provided with a liquid storage cavity 360 for accommodating additives inside; the distributor box 3 includes a latch 4, which is movably arranged in the distributor box 3, has one end protruding from the outer peripheral wall of the distributor box 3 and plugged into the plug-in portion 210 provided on the inner peripheral wall of the water box 2 in a first position, and retracted in the distributor box 3 in a second position; a rotating component 5, which is rotatably arranged in the distributor box 3, is transmission-connected with the latch 4, and drives the latch 4 to switch between the first position and the second position by rotating in the forward and reverse directions.

[0038] Through the above-mentioned setting, by setting the rotating component 5, the rotating component 5 drives the pin 4 to be plugged into or disengaged from the plug-in portion 210 through forward and reverse rotation, thereby controlling the lock or unlocking of the dispenser box 3 and the water box 2, so as to achieve stable locking of the dispenser box 3 and prevent the dispenser box 3 from accidentally disengaging from the water box 2.

[0039] In an embodiment of the present invention, the rotating assembly 5 at least includes a wheel disc 510 and a transmission rod 520 perpendicular to the rotation direction, and the transmission rod 520 and the wheel disc 510 rotate around the rotation axis; a slideway 511 is provided on the wheel disc 510, and the slideway 511 is an elliptical arc centered on the rotation axis, and one end of the pin 4 is slidably arranged in the slideway 511; the elliptical arc track has the characteristic of gradually changing diameter along the extension direction of the track, so that during the rotation of the wheel disc 510, the connection end of the pin 4 connected to the track is gradually increased or decreased in distance from the center of the wheel disc 510, so as to realize that the pin 4 protrudes outward to the first position or retracts inward to the second position.

[0040] The structure of the slideway 511 is an elliptical arc extending from the major axis of the ellipse along the outer circumference of the ellipse to the minor axis, or an elliptical arc extending from the minor axis of the ellipse along the outer circumference of the ellipse to the major axis.

[0041] Through the above arrangement, the radius of the elliptical arc slide 511 gradually increases or decreases from one end to the other end, so that the wheel 510 can only rotate in the forward and reverse directions to switch the latch 4 from the first position to the second position or from the second position to the first position, thereby facilitating the control of locking or unlocking the dispenser box 3.

[0042] In the embodiment of the present invention, the angle of the elliptical arc slideway 511 is less than or equal to 90 degrees.

[0043] In an embodiment of the present invention, the wheel 510 is respectively provided with positioning holes 512 at both ends of each slide 511, and the sliding end of the latch 4 connected to the slide 511 is connected to an elastic positioning protrusion 410; when the latch 4 is in the first position or the second position, the positioning protrusion 410 is engaged in the corresponding positioning hole 512; the latch 4 is positioned by the positioning protrusion 410 and the positioning hole 512, so that the latch 4 is stably limited to the first position or the second position; at the same time, by making the positioning protrusion 410 elastic, when it is necessary to switch the position of the latch 4, the positioning protrusion 410 is compressed and deformed to disengage from the positioning hole 512, thereby realizing the unlocking of the limit of the latch 4.

[0044] In an embodiment of the present invention, the slide 511 is composed of a strip-shaped groove that is recessed inwardly on the bottom surface of the wheel disc 510; each pin 4 is provided with a Z-shaped bending portion 420 that bends downward and extends toward the center of the wheel disc 510 at one end thereof; a positioning protrusion 410 that protrudes upward is provided on the Z-shaped bending portion 420, and the positioning protrusion 410 can be slidably inserted into the slide 511.

[0045] In an embodiment of the present invention, the positioning protrusion 410 is an upwardly protruding U-shaped press-formed structure provided at the extended end of the bending portion 420; when in use, the positioning protrusion 410 can be elastically deformed through the press-formed structure, and when the wheel 510 switches between the first position and the second position, the positioning protrusion 410 is disengaged from the positioning hole 512 through compression deformation, and after the switching is completed, it extends into the corresponding other positioning hole 512 through its own elastic deformation to achieve positioning.

[0046] In the embodiment of the present invention, the extended end of one end of the transmission rod 520 is connected to a motor; the forward and reverse rotation of the motor drives the wheel 510 to rotate, thereby controlling the latch 4 to switch between the first position and the second position.

[0047] In an embodiment of the present invention, an extended end of one end of the transmission rod 520 passes through the dispenser box 3 and extends to the outside of the dispenser box 3; the extended end of the transmission rod 520 is connected to a knob 530, and the knob 530 is transmission-connected to the latch 4 through the transmission rod 520 and the wheel 510; by setting the knob 530, the user can drive the wheel 510 to rotate through the knob 530, and the knob 530 is located outside the dispenser box 3 for the convenience of the user to hold.

[0048] In an embodiment of the present invention, the transmission rod 520 includes a transmission support rod 521, one end of which is rotatably connected to the center of the elliptical wheel 510, and the other end of which is connected to the center of the knob 530, so that the knob 530 is coaxially arranged with the wheel 510; a transmission drive rod 522, which is arranged parallel to the support rod, and a drive port 340 connected to the mounting groove 312 is provided at the bottom of the handle portion 310, and the transmission drive rod 522 is slidably arranged in the drive port 340, and the transmission drive rod 522 is rotatably connected to the wheel 510 through the drive port 340, and the connection is located on the major axis or minor axis of the elliptical wheel 510.

[0049] Through the above arrangement, when the user rotates the knob 530, the transmission support rod 521 ensures that the knob 530 and the wheel 510 always remain coaxially arranged, and the transmission drive rod 522 drives the wheel 510 to rotate around the axis of the transmission connecting rod, thereby achieving the synchronous rotation of the knob 530 and the wheel 510 at the same angle.

[0050] The driving opening 340 is an arc-shaped strip structure cocentric with the wheel disc 510 ; the sliding direction of the transmission driving rod 522 is limited by the driving opening 340 .

[0051] In the embodiment of the present invention, a limiting channel 331 extending in the radial direction of the wheel disc 510 is provided in the distributor box 3 , and the latch 4 is slidably disposed in the limiting channel 331 .

[0052] In an embodiment of the present invention, a driving cavity 330 for accommodating the latch 4 and the rotating assembly 5 is provided in the dispenser box 3, and a limiting rib 332 protruding from the cavity wall is provided in the driving cavity 330; each limiting rib 332 extends from both sides of the corresponding latch 4 respectively, and cooperates to form a limiting channel 331.

[0053] In the embodiment of the present invention, the limiting ribs 332 are strip structures perpendicular to the extension direction of the latch 4 , and each extension rib is arranged on both sides of the latch 4 in parallel with the extension direction of the latch 4 .

[0054] In an embodiment of the present invention, a plurality of slideways 511 are arranged at equal angles along the circumference of the wheel 510, and each slideway 511 is slidably connected with a latch 4 in a one-to-one correspondence, and each latch 4 extends radially outward along the transmission rod 520; by providing a plurality of slideways 511, a plurality of latches 4 can be synchronously extended or retracted when the wheel 510 is rotated, so as to improve the stability of locking the dispenser box 3, and at the same time, by providing a plurality of latches 4, the strength of supporting the dispenser box 3 is effectively improved to withstand greater strength.

[0055] In the embodiment of the present invention, the wheel disc 510 is connected to two latches 4, and the two latches 4 are arranged opposite to each other.

[0056] In an embodiment of the present invention, the dispenser box 3 is provided along the pulling direction with a bearing portion 320, which is located inside the water box 2 and is used to hold additives; a handle portion 310, which at least partially protrudes from the water box 2; the handle portion 310 has a mounting groove 312 opening toward the bearing portion 320, and the bearing portion 320 is correspondingly snapped into the mounting groove 312, and the groove bottom of the mounting groove 312 is spaced apart from the bearing portion 320 to form a driving cavity 330, and the rotating assembly 5 and the latch 4 are respectively arranged in the driving cavity 330, and a connecting port 311 is opened on the groove wall of the mounting groove 312, and each latch 4 switches between the first position and the second position through the corresponding connecting port 311.

[0057] Through the above arrangement, by making the bearing part 320 and the handle part 310 separately arranged, the latch 4 and the rotating component 5 are arranged in the openable driving cavity 330, which can not only provide relatively independent chambers for the latch 4 and the rotating component 5, but also prevent dust, water and additives from adhering to the rotating component 5, and avoid the adhered impurities from affecting the rotation smoothness of the rotating component 5; at the same time, by separating the bearing part 320 from the handle part 310, it can bring convenience to the installation, repair or replacement of the rotating component 5.

[0058] In the embodiment of the present invention, the limiting ribs 332 are respectively arranged on the surface of the bearing portion 320 .

[0059] In an embodiment of the present invention, a circular rotating groove 324 recessed inward is provided on the side of the bearing portion 320 facing the handle portion 310, and the wheel 510 is rotatably arranged in the rotating groove 324; the center of the rotating groove 324 is arranged to coincide with the axis of the transmission rod 520.

[0060] In an embodiment of the present invention, the roulette wheel 510 is an elliptical roulette wheel 510, and the outer edge of the long axis of the elliptical roulette wheel 510 is arranged to fit the groove wall of the rotating groove 324; by setting the elliptical roulette wheel 510, the groove wall of the rotating groove 324 limits the rotation of the roulette wheel 510 to prevent the wheel row from deviating. At the same time, the contact area between the elliptical roulette wheel 510 and the groove wall is small, and the friction force generated is also small, thereby preventing the groove wall of the rotating groove 324 from affecting the smoothness of the rotation of the roulette wheel 510.

[0061] In the embodiment of the present invention, the connection position of the transmission driving rod 522 is located on the long axis of the elliptical wheel 510 and between the transmission support rod 521 and the corresponding elliptical arc slide 511 .

[0062] In the embodiment of the present invention, the transmission rod 520 includes two transmission driving rods 522 , and the two transmission rods 520 are symmetrically arranged on both sides of the transmission connecting rod.

[0063] In the embodiment of the present invention, the lower end of each transmission driving rod 522 is connected to the middle part of the transmission connecting rod respectively.

[0064] In another embodiment of the present invention, the lower end of the transmission connecting rod is connected to the upper surface of the knob 530 .

[0065] In an embodiment of the present invention, a downwardly protruding cylindrical sleeve portion 513 is coaxially arranged at the bottom of the wheel 510 and the transmission rod 520, and the sleeve portion 513 is sleeved on the outside of the transmission rod 520; a torsion spring 514 is sleeved on the outside of the sleeve portion, one end of the torsion spring 514 is connected to the wheel 510, and the other end opposite to the distributor box 3, and the compression amount of the torsion spring 514 when the wheel 510 is in the first position is less than the compression amount of the wheel 510 when the wheel 510 is in the second position.

[0066] Through the above arrangement, the rotating assembly 5 can automatically rotate to the first position through the action of the torsion spring 514 when there is no external force driving it. When in use, the user only needs to rotate the rotating assembly 5 and the latch 4 to the second position, and remove or install the dispenser box 3 to remove the external force applied to the rotating assembly 5. The torsion spring 514 drives the rotating assembly 5 and the latch 4 to automatically switch to the first position through its own elastic force, which brings convenience to the user to operate the rotating assembly 5; and the rotating assembly 5 and the latch 4 are maintained in the first position under the action of the torsion spring 514, ensuring the stable connection between the dispenser box 3 and the water box 2, and preventing the dispenser box 3 from accidentally falling out.

[0067] In the embodiment of the present invention, the plug-in portion 210 of the water box 2 is a lock port 211 arranged opposite to each communication port 311 , and the lock port 211 penetrates the peripheral side wall of the water box 2 ; when the latch 4 is in the first position, it is correspondingly inserted into the lock port 211 .

[0068] In an embodiment of the present invention, the latch 4 is an elongated structure, and the wider surface of the elongated latch 4 is arranged perpendicular to the pulling direction of the dispenser box 3; so as to increase the contact area between the latch 4 and the lock 211 in the force direction, reduce the pressure on the latch 4 and the lock 211, improve the structural strength of the latch 4, and avoid deformation or breakage of the latch 4 and damage.

[0069] In the embodiment of the present invention, the end surface of the extended end of the bolt 4 that penetrates the lock opening 211 is set as an arc surface, so as to facilitate the insertion of the bolt 4 into the lock opening 211 and prevent the end of the extended end of the bolt 4 from wearing the lock opening 211.

[0070] In an embodiment of the present invention, the knob 530 is a disc structure, and a hand-held portion 531 protruding outward is provided on a side surface of the knob 530 away from the transmission rod 520. The hand-held portion 531 is a long strip structure extending parallel to the side surface, so that the user can hold and operate the knob 530 to rotate.

[0071] In the embodiment of the present invention, both ends of the long strip-shaped handle portion 531 are arc-shaped surfaces that are bent and extended toward the knob 530 , making both ends of the handle portion 531 smoother and providing a comfortable grip.

[0072] In the embodiment of the present invention, a hand hole 532 is provided on the side of the elongated hand-held portion 531 and passes through the hand-held portion 531 ; when in use, the user can insert a finger into the hand hole 532 to facilitate the user to apply force, so that users with small hands can also easily operate the knob 530 .

[0074] In an embodiment of the present invention, a movable tube 250 extending along the pulling direction of the distributor box 3 is provided in the water box 2, and a pin assembly 260 is movably provided in the movable tube 250 along the extending direction of the movable tube 250. A first abutting portion 252 protruding inward is provided at one end of the movable tube 250 close to the distributor box 3, and a first elastic member 263 extending toward the opposite end is provided at the end away from the distributor box 3; when the distributor box 3 is pulled out of the water box 2, the pin assembly 260 is sealed against the first abutting portion 252 through the first elastic member 263; when the distributor box 3 is pushed back into the water box 2, the distributor box pushes the pin assembly 260 to move in the direction of the first elastic member 263, and the pin assembly 260 is spaced apart from the first abutting portion 252.

[0075] In the embodiment of the present invention, the movable tube 250 is connected to at least one flow channel of the water box 2 for the flow of incoming water.

[0076] In an embodiment of the present invention, the ejector assembly 260 includes, in sequence along the direction away from the dispenser box 3, an ejector tube 261, a front end of which is used to push the spring assembly 352 provided on the additive outlet 351 of the dispenser box 3, so that the ejector tube 261 is connected to the liquid storage chamber 360; a first sealing portion 262, which is radially protruding from the ejector tube 261 and abuts against the first abutting portion 252 in a shape matching with each other.

[0078] Through the above arrangement, the ejector assembly 260 can automatically block the movable tube 250 when the ink cartridge is pulled out, thereby preventing the additive in the movable tube 250 from flowing out into the installation cavity of the water box 2 that accommodates the dispenser box when the ink cartridge is pulled out.

[0079] In the embodiment of the present invention, the first elastic member 263 is a spring.

[0080] In an embodiment of the present invention, one end of the movable tube 250 away from the dispenser box 3 is bent and extended, one end of the first elastic member 263 is connected to the tube wall at the bending point of the movable tube 250, and the other end of the first elastic member 263 is connected to the first sealing portion 262; the first sealing portion 262 is provided with a first stop portion 264 extending in a direction away from the dispenser box 3, and the first elastic member 263 is sleeved on the columnar first stop portion 264; when the dispenser box 3 is pulled out of the water box, the first stop portion 264 is spaced from the tube wall at the bending point of the movable tube 250; when the dispenser box 3 is pushed back into the water box, the first stop portion 264 abuts against the tube wall at the bending point of the movable tube 250, and the ejector tube 261 abuts against the spring assembly 352 of the dispenser box.

[0081] Through the above arrangement, when the dispenser box 3 is inserted, the displacement distance of the ejector assembly 260 is limited by the first stop portion 264 to prevent the ejector assembly 260 from being excessively displaced. The length extended by the movable tube 250 is insufficient to trigger the spring assembly 352, resulting in poor communication between the ejector assembly 260 and the liquid storage chamber 360.

[0082] In the embodiment of the present invention, the tube wall at the bend of the movable tube 250 is provided with an inwardly recessed receiving groove 251 , one end of the first elastic member 263 is connected to the groove bottom or groove wall of the receiving groove 251 , and the first stopper 264 is movably arranged in the receiving groove 251 .

[0083] In an embodiment of the present invention, the first abutment portion 252 is an annular inclined surface protruding inward, and a shape-matching inclined surface structure is provided on the first sealing portion 262. The first sealing portion 262 and the first abutment portion 252 are in shape-matching contact with each other, so that when the first sealing portion 262 abuts against the first abutment portion 252, sealing is achieved through tight fit.

[0084] In the embodiment of the present invention, a sealing ring is sleeved on the first sealing portion 262 to further improve the sealing effect.

[0085] In the embodiment of the present invention, the dispenser box 3 is provided with a sleeve portion 350 that is recessed inward, and an additive outlet 351 is provided at the bottom end of the sleeve portion 350, and the ejector assembly 260 is inserted into the sleeve portion 350. This improves the assembly strength of the ejector assembly 260 and the dispenser box, so that the ejector assembly 260 and the liquid storage chamber 360 can be stably connected.

[0086] In an embodiment of the present invention, the movable tube 250 is inserted into the interior of the sleeve portion 350, and at least one circle of sealing ring is sleeved on the outer peripheral wall of the movable tube 250. The outer side of the sealing ring abuts against the peripheral wall of the sleeve portion 350, thereby improving the sealing between the sleeve portion 350 and the movable tube 250, and preventing the additive from flowing from the gap between the sleeve portion 350 and the movable tube 250 to the outside of the dispenser box 3.

[0087] like Figure 1-9 As shown, in an embodiment of the present invention, a wall-mounted washing machine is also introduced, including a washing chamber for providing a space for accommodating clothes; and a dispensing device 1 as described above is used.

[0088] Since wall-mounted washing machines are usually used in hotels, apartments and other places, the depreciation rate of electrical appliances in the above places is faster than that in home use. By adopting the structure of the latch 4, the overall use experience of the wall-mounted washing machine can be prevented from being affected by the spring damage of the push-open device, making the water box 2 of the wall-mounted washing machine more durable and meeting the use requirements of the above places.

[0089] In an embodiment of the present invention, a wall-mounted washing machine is suspended on a wall; an opening is provided at the bottom of the water box 2 for the dispenser box 3 to pass through, and the dispenser box 3 is switched to the first position and positioned in the water box 2 by a latch 4; the dispensing device 1 is arranged at the bottom of the casing, and an additive replenishing port is provided at the bottom of the casing for the dispenser box 3 to extend out of.

[0090] Through the above arrangement, the latch 4 has a higher structural strength than the locking protrusion of the push-open device. Even if the water box 2 is vertically arranged in the wall-mounted washing machine, the latch 4 can provide stable support for the dispenser box 3, thereby realizing the vertical arrangement of the water box 2 inside the wall-mounted washing machine, reducing the length of the washing machine protruding outward from the wall, making the wall-mounted washing machine more adaptable to narrow spaces.

[0091] In an embodiment of the present invention, a flow channel is provided on the top of the water box 2, and the flow channel at least includes a water delivery channel 220; a connecting structure connected to the distributor box 3 is provided in the water box 2, and the liquid outlet end of the connecting structure extends vertically upward and is connected to the water delivery channel 220; so that the additive and the incoming water are mixed in the water delivery channel 220 to form a mixed liquid.

[0092] In addition, the existing dispensing device 1 usually adopts a dispenser box 3 that is inserted into the dispensing device 1 through the horizontal opening of the water box 2. The connecting structure arranged in the water box 2 includes a horizontally extending liquid suction end and an upwardly bent liquid outlet end connected to the dispensing water channel 220. Such a setting requires the horizontally extending liquid suction end to occupy the horizontal space of the water box 2, which increases the horizontal length requirement of the water box 2, thereby requiring the wall-mounted washing machine to increase the horizontal length to accommodate the water box 2.

[0093] Through the arrangement of the above embodiment, the distributor box 3 is vertically inserted into the water box 2 so that the liquid suction end of the connecting structure extends vertically downward, thereby reducing the horizontal space occupied by the connecting structure and reducing the thickness of the wall-mounted washing machine.

[0094] In an embodiment of the present invention, the carrying portion 320 is a replaceable ink cartridge structure, and a connecting tube connected to the water box is provided on the top of the carrying portion; the carrying portion 320 in which the liquid storage chamber 360 is provided is arranged to be replaceable, and the additive in the carrying portion 320 can be directly discarded after use, and a new carrying portion 320 can be replaced, thereby reducing the operation of pouring the additive into the dispenser box, and providing convenience for users.

[0095] In the embodiment of the present invention, the latch 4 and the rotating assembly 5 are disposed in the driving cavity 330 between the bearing portion 320 and the handle portion 310 .

[0096] In the embodiment of the present invention, each limiting rib 332 is respectively disposed on the lower surface of the bearing portion 320 and / or the upper surface of the handle portion 310 .

[0097] In the embodiment of the present invention, a circular rotating groove 324 recessed inward is respectively provided on the lower surface of the bearing portion 320 and / or the upper surface of the handle portion 310 , and the wheel 510 of the rotating component 5 is rotatably disposed in the rotating groove 324 .

A mixing structure 222 is provided in the mixing chamber 221 , and the mixed liquid flowing into the mixing chamber 221 is stirred and mixed by the mixing structure 222 .

[0099] In the embodiment of the present invention, the mixing structure 222 includes a positioning column 223 vertically disposed in the mixing chamber 221 , and a mixing impeller 224 rotatably mounted on the positioning column 223 .

[0100] Through the above arrangement, water flows into the mixing chamber 221 to drive the mixing impeller 224 to rotate. At the same time, the rotating mixing impeller 224 mixes and stirs the mixed liquid in the mixing chamber 221, so as to achieve the mixing structure 222 stirring the mixed liquid without motor drive.

[0101] In an embodiment of the present invention, the water box 2 is further provided with an additive waterway 230, which is relatively independent of the delivery waterway 220; a suction component 231 has a negative pressure chamber inside which can generate negative pressure for sucking the additive, the liquid inlet end of the suction component 231 is connected to the liquid outlet end of the additive waterway 230, and the liquid outlet end of the suction component 231 is connected to the delivery waterway 220.

[0102] In the embodiment of the present invention, the liquid outlet end of the suction assembly 231 is located upstream of the mixing chamber 221 .

[0103] In the embodiment of the present invention, the suction component 231 is a suction pump, which rotates the impeller in the negative pressure chamber by powering on, thereby generating negative pressure to suck the additive.

[0104] In an embodiment of the present invention, the suction component 231 is a Venturi tube, and water enters the suction component 231 through the water inlet of the suction component 231 and is discharged through the liquid outlet. The liquid inlet of the suction component 231 is connected to the throat of the Venturi tube. The water inlet forms a negative pressure chamber with negative pressure inside the throat, and the additive is sucked by the negative pressure.

[0105] In an embodiment of the present invention, a buffer chamber 240 is provided downstream of the mixing chamber 221 in the water channel 220, and sheet-like buffer ribs 241 arranged perpendicular to the flow direction of the mixed liquid are distributed in the buffer chamber 240. By allowing the mixed liquid to impact the surface of the buffer rib 241, the mixed liquid is further mixed, thereby improving the mixing effect.

[0106] In an embodiment of the present invention, the passing area of ​​the buffer chamber 240 is larger than the passing area of ​​the delivery waterway 220, so that the flow velocity of the mixed liquid in the buffer chamber 240 is reduced, the mixed liquid can obtain a steady flow in the buffer chamber 240, the flow rate of the mixed liquid is adjusted, and the mixed liquid passes through the downstream delivery waterway 220 at a uniform speed.
