Description

Clothing stain cleaning device and washing area adjusting structure thereof

Technical field

The invention relates to the field of clothing cleaning, in particular to a clothing stain cleaning device and a washing area adjusting structure thereof.

Background technique

There are existing methods for washing clothes with machine washing and hand washing. When the clothes only need to clean local stains, both washing methods are difficult to meet. Machine washing cannot achieve targeted targeted cleaning, and requires a sufficient amount of water and time; when washing by hand, it is difficult to grasp the area to be cleaned for local cleaning, which may cause damage to local stains. The effect of large areas around the stain, such as contamination with detergent and water.

The invention with patent application number CN201710262349.6 discloses a method and device for locally cleaning and decontaminating textiles. The technical scheme and working principle of the invention are: the device is divided into a water inlet device and a water outlet device, and the water inlet device is connected to a vessel containing fresh water The water outlet device is connected to a waterproof suction fan. The water inlet device is placed on the back of the stained part of the textile. The water outlet device is placed directly above the water inlet device and the stained part of the textile. The water inlet device and the water outlet device clamp the textile and use the suction The suction of the fan makes the clear water in the vessel quickly pass through the stained part of the textile, continuously dilutes and takes away the cleaning essence and stain, and discharges it, thereby achieving the purpose of thoroughly cleaning the local stain.

It can be seen that the shortcomings in the above patents are as follows: ① For different sizes of stains on different textiles, a single application is applicable, for example, two kinds of textiles with different stains, and the same choice of using the cleaning device used in the above patents, will The washing area of two kinds of textiles with different stain sizes is close to the same, because the device used in the above patent does not involve a structure that can be adaptively selected according to the size of the stain to adjust the washing area. However, in actual cases, for local stains, the size of the stains There are still different sizes, and a single applicable cleaning device cannot meet the needs of practical use; ② Only the suction of the suction fan can be used to wash clean water through the spot of the textile quickly. The washing intensity is not high, and the washing effect is also lacking. Repeat the cleaning process to achieve the purpose of thorough cleaning. This is not only tedious to operate, but also in the process of continuous repeated cleaning, the greater the number of repetitions, it will also cause the textile fabrics around the stains to be stained with detergent and water during the cleaning process. Increased probability.

Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

Example 1:

Please refer to FIG. 1 to FIG. 4. This embodiment provides a washing area adjusting structure for a clothing stain cleaning device, which includes at least two-stage sealing rings suitable for nesting and connecting; at least two-stage sealing rings each include an axial direction. Through-holes. The inner diameters of the corresponding through-holes of the at least two-stage sealing rings are different; and the sealing ring with the smaller inner diameter of the through-hole in the sealing ring is suitable for being embedded in the sealing ring with the larger inner diameter of the through-hole; An annular ring wall (a ring wall of the seal ring, in other words, an outer cylindrical surface of the seal ring) of the ring wall of the through hole of the seal ring is provided radially on the hole wall and is suitable for supporting the seal ring. Steps 24.

As an optional implementation manner, the washing area adjusting structure includes a three-stage sealing ring suitable for nesting and connecting; specifically, the three-stage sealing ring here includes a first sealing ring and a second sealing in which the inner diameter of the through hole is sequentially reduced. A ring and a third seal ring; and the hole wall of the through hole of the first seal ring is radially provided with a step 24 adapted to support the ring wall of the second seal ring; the hole wall of the through hole of the second seal ring is radially provided on the hole wall A step 24 is provided which is adapted to support a ring wall of the third sealing ring. That is, the area through which the washing liquid flows from the sealing ring is adjusted through the sealing rings with different inner diameters of the through holes, so that during the stain cleaning of the clothing cloth 16, the corresponding cleaning area can be adjusted according to the size of the stain of the clothing cloth 16.

Please refer to FIG. 2. As another optional embodiment, the washing area adjusting structure includes a two-stage sealing ring suitable for nesting and connecting; the two-stage sealing ring includes a large sealing ring 4 with a large inner diameter of the through hole and a through hole. A small sealing ring 5 with a small inner diameter of the hole; and a hole wall of the through hole of the large sealing ring 4 is radially provided with a step 24 adapted to support the ring wall of the small sealing ring 5, that is, the step 24 is used to inlay in the large The small sealing ring 5 inside the sealing ring 4 is positioned axially. This embodiment takes a two-stage seal ring as an example. Both the large seal ring 4 and the small seal ring 5 are made of elastic material, so that the large seal ring 4 and the small seal ring 5 can be fitted with an interference insert.

What needs to be explained here is that, referring to FIG. 3, the specific position of the step 24 relative to the hole wall of the through hole of the large seal ring 4 may be the middle part of the through hole of the large seal ring 4 in the axial direction, or may be a large The middle of the axial direction of the through hole of the seal ring 4 is located on the side of the clothing fabric 16. Of course, the middle of the axial direction of the through hole of the large seal ring 4 is located on the side away from the clothing fabric 16, which meets the requirements of this embodiment. The drawings of this embodiment (see FIG. 1 and FIG. 3) only take the case where the step 24 is disposed on the side of the through hole of the large seal ring 4 in the axial center portion away from the clothing fabric 16 side as an example.

Please refer to FIG. 3 and FIG. 4. In order to improve the rigidity of the large sealing ring 4 and the small sealing ring 5, so that the tightness of the fit between the clothing cloth 16 and the clothing cloth 16 is maintained when clamping the clothing cloth 16. The inside of 5 is integrally provided with a small ring-shaped skeleton 25 along the radial direction of the small seal ring 5. Similarly, a large annular frame 26 is integrally provided inside the large sealing ring 4 along the radial direction of the large sealing ring 4. Here, the small skeleton 25 and the large skeleton 26 are used to increase the rigidity of the small seal ring 5 and the large seal ring 4, respectively, so that the small seal ring 5 and the large seal ring 4 have the properties of internal rigidity and external elasticity at the same time.

Please refer to FIG. 3 and FIG. 4. In order to enrich the selectivity of the two-stage sealing ring for the area adjustment during the stain cleaning of the clothing cloth 16, the large sealing ring 4 in the two-stage sealing ring is adapted to face the end face of the clothing cloth 16. A raised annular oversized seal ring 23 is provided; the inner diameter of the oversized seal ring 23 is larger than the inner diameter of the through hole of the large seal ring 4. The small sealing ring 5 is adapted to be provided with a raised annular small sealing ring 20 on an end face inlaid with the large sealing ring 4. The inner diameter of the small sealing ring 20 is equal to the inner diameter of the through hole of the small sealing ring 5. The small seal ring 5 is adapted to be provided with a raised annular middle seal ring 21 on the end face facing the clothing fabric 16; the inner diameter of the middle seal ring 21 is larger than the inner diameter of the through hole of the small seal ring 5 and the inner diameter of the middle seal ring 21 It is smaller than the inner diameter of the through hole of the large seal ring 4.

Specifically, the specific implementation of the design here in actual use is as follows:

Please refer to FIG. 1. The large sealing ring 4 and the small sealing ring 5 involved in the two-stage sealing ring are both sealing rings that can be used on both sides. That is, during the assembly process, the sealing ring can be installed in both the upside and the downside. By combining the large seal ring 23 provided on the large seal ring 4 and the middle seal ring 21 provided on the small seal ring 5, it can be used when the large seal ring 4 and the small seal ring 5 are assembled differently (that is, front-mounted and inverted-mounted). ) The difference in the washing area of the clothing fabric 16 is achieved.

Among them, in the case of large stains on the clothing fabric 16, the two-stage sealing ring only uses the large sealing ring 4 to facilitate corresponding cleaning of the clothing fabric 16 with large stains. In this case, when the large sealing ring of the large sealing ring 4 is oversized, When 23 is facing the clothing fabric 16 side, at this time, because the inner diameter of the oversized sealing ring 23 is larger than the inner diameter of the through hole of the large sealing ring 4, the washing area formed when the washing liquid finally flows through the oversized sealing ring 23 to the clothing fabric 16 is larger than Washing area through the through hole of the large seal ring 4. Conversely, when the oversized seal ring 23 of the large seal ring 4 faces away from the clothing cloth 16 side, at this time, because the inner diameter of the oversized seal ring 23 is larger than the inner diameter of the through hole of the large seal ring 4, the washing liquid finally passes through the large seal ring The washing area formed when the through holes 4 flow to the clothing fabric 16 is smaller than the washing area formed when the washing liquid passes through the oversized seal 23. Therefore, when the large seal ring 4 is used alone, the two washing areas may be different.

Among them, please refer to FIG. 2. For the case where the stain on the clothing cloth 16 is relatively small, the small sealing ring 5 nested in the large sealing ring 4 is selected to realize small area washing control. Since the small sealing ring 5 is directly embedded in the large sealing ring 4 when the small sealing ring 5 is used here, the installation direction of the large sealing ring 4 relative to the clothing fabric 16 at this time does not affect the small sealing ring 5 Use, so the mounting direction is not limited to which one, the drawings of this embodiment only take the case where the oversized seal ring 23 of the large seal ring 4 faces the cloth material 16 side as an example. Specifically, when the small seal ring 5 is embedded in the large seal ring 4, and the middle seal ring 21 faces the clothing cloth 16 side, the inner diameter of the middle seal ring 21 is larger than the inner diameter of the through hole of the small seal ring 5. The washing area formed when the washing liquid finally flows through the middle sealing ring 21 to the clothing fabric 16 is larger than the washing area passing through the through hole of the small sealing ring 5; conversely, when the middle sealing ring 21 faces the side facing away from the clothing fabric 16 due to the middle sealing The inner diameter of the ring 21 is larger than the inner diameter of the through hole of the small seal ring 5, so at this time, the washing area formed when the washing liquid finally flows through the through hole of the small seal ring 5 to the clothing cloth 16 is smaller than the washing formed when the middle seal ring 21 is passed area. Therefore, for different installation methods of the small seal ring 5, two different washing areas can also be obtained. It should be particularly noted here that when the small seal ring 5 and the large seal ring 4 are inlaid for use, the end face of the small seal ring 5 facing the clothing cloth 16 needs to protrude from the end face of the large seal ring 4 toward the clothing cloth 16 or The end face of the small seal ring 5 facing the clothing fabric 16 is flush with the end face of the large seal ring 4 facing the clothing fabric 16. Such a design can effectively ensure that the small seal ring 5 exerts a control effect on the cleaning area of the clothing fabric 16.

It should be noted that, through the selection of the use of different seal rings and the selection of the installation direction of the seal ring, the situation of the washing area can be enriched, which is suitable for stains of different sizes on the clothing fabric 16. Moreover, the above-mentioned diversity of the washing area is not only applicable to stains of different sizes, but also has other functions. Specifically, in the process of cleaning the stains on the clothing cloth 16, a washing process of detergent is usually required, and After the washing process of the detergent is completed, a rinsing process with fresh water is also required. If the washing area is not adjustable, for the same area of washing liquid washing and water rinsing, such a structure is likely to cause insufficient rinsing or need to be repeated many times. The rinsing achieves the effect of rinsing and cleaning. By using the washing area adjustment structure of this embodiment, the use of the sealing ring can be adjusted to specifically control the washing area corresponding to clean water rinsing larger than the washing area corresponding to detergent washing, so that the water is rinsed. The area is larger than the washing area of the detergent to achieve an effective rinsing effect.

Example 2:

Please refer to FIG. 1. Based on the washing area adjustment structure of Embodiment 1, this embodiment provides a clothing stain cleaning device, which is particularly suitable for cleaning and permeable clothing with relatively thin thickness. The clothing stain cleaning device of this embodiment includes upper and lower washing devices respectively adapted to be positioned above and below the stains of the clothing cloth 16 to hold the clothing cloth 16 and a kettle 14 connected to the lower washing tool.

Please refer to FIG. 2, the upper washing tool includes a tank body 1 suitable for storing a washing liquid, a sinker hole 2 provided at the bottom end of the tank body 1 and integrally penetrating with the tank body 1, and embedded in the sinker hole 2. As in the washing area adjusting structure of the embodiment 1, and a ring-shaped magnetic load bearing block 3 embedded in the bottom end surface of the tank body 1 and surrounding the sink hole 2, a bottom end of the tank body 1 and the sink hole 2 are formed.环梁台 22。 The annular boss 22. Here, the fluid (the washing liquid mixed with the detergent or the clean water) medium circulating in the tank 1 can flow into the sink hole 2, and finally discharged from the sink hole 2 to the clothing cloth 16. Specifically, the washing area adjustment structure here is assembled with the sinkhole 2 in this way. The number of sealing rings used by the specific washing area adjustment structure is selected according to the size of the stain on the actual clothing fabric 16. When only a large seal is used, For the ring 4, the installation direction of the large sealing ring 4 is adjusted according to the stain of the clothing cloth 16 according to the case of Example 1. The large sealing ring 4 is inlaid in the countersink 2 and abuts on the annular boss 22. The assembly of the large sealing ring 4 and the countersink hole 2 can be completed. When it is necessary to use the large sealing ring 4 and the small sealing ring 5 at the same time, the large sealing ring 4 is inlaid in the countersink hole 2 and abuts on the annular boss 22, and then the small size is selected according to the stain of the actual clothing cloth 16 In the assembly direction of the seal ring 5, the small seal ring 5 is inserted into the large seal ring 4 in an interference fit, and the small seal ring 5 abuts on the step 24 of the through hole of the large seal ring 4 to realize the small seal ring 5 and Assembly of the large seal ring 4.

Please refer to FIG. 5, the lower washing device includes an outer pipe 6 suitable for circulating washing liquid, a drain pipe 11 communicating with the far garment cloth 16 end of the outer pipe 6, and an outer pipe 6 provided near the garment cloth 16 end of the outer pipe 6. The sinking hole 12 communicating with the pipe 6, the washing area adjusting structure embedded in the sinking hole 12 and the washing area adjusting structure in the sinking hole 2 are mirror-symmetrically distributed as in the washing area adjusting structure of Embodiment 1, the drain pipe 11 and the sinking hole 12 Set on the same axis. An annular boss 22 is formed between the top of the outer tube 6 and the sinking hole 12. For specific assembly issues of the washing area adjusting structure and the sinking hole 12, the same can be referred to the washing area adjusting structure in the sinking hole 2. . An annular permanent magnet 13 embedded at the end of the outer tube 6 near the clothing fabric 16 and surrounding the sink hole 12; the permanent magnet 13 is adapted to be magnetically attracted to the magnetic bearing block 3. Specifically, the lower end of the outer pipe 6 is connected to the drain pipe 11 and connected to form a circulation channel of the washing liquid, so that the fluid medium in the outer pipe 6 can flow into the drain pipe 11.

What needs to be explained here is that, referring to FIG. 2 and FIG. 5, the washing area adjustment structures respectively provided in the upper and lower washing appliances are mirror-distributed, that is, the same structure is adopted, specifically the number of sealing rings used. And the installation manner of the seal ring achieves the same control of the washing area of the upper and lower surfaces of the clothing fabric 16 by way of mirror distribution. Since the sinking holes 2 and the sinking holes 12 are used to support the assembly of the washing area adjustment structure, respectively, when the washing area adjusting structures provided in the upper and lower washing devices are mirror-distributed, the upper sinking holes 2 and the sinking holes 12 are also distributed. It has a mirror-symmetrical structure, specifically, the structure and size of the sinkhole 2 and the sinkhole 12 are the same.

The water receiving pot 14 includes a water receiving port 15 for connecting with the drain pipe 11 and a pot cavity for storing washing liquid, which is connected to the water receiving port 15; For the suction pipe 9 connected to the external suction pump. In this embodiment, the method of connecting the drain pipe 11 to the water receiving port 15 is to insert the drain pipe 11 into the water receiving port 15 to form a connection between the two. The reason why the suction pipe 9 is provided on the top surface of the kettle 14 is to make the height difference between the suction pipe 9 and the liquid surface in the kettle cavity of the kettle 14 as large as possible to prevent liquid from being sucked into the suction pipe 9.

Please refer to FIG. 1, in order to facilitate the assembly between the drain pipe 11 and the water inlet 15 of the kettle 14, the radial dimension of the outer pipe 6 designed in this embodiment is larger than the radial dimension of the drain pipe 11. To further improve the tightness of the connection between the drain pipe 11 and the water inlet 15 of the water bottle 14, a ring seal 27 is provided on the outer side of the transition between the outer pipe 6 and the drain pipe 11, and the water inlet 15 and the drain pipe 11 are sealed by a ring. The ring 27 is sealed to prevent air from entering through the gap between the water inlet 15 and the drain pipe 11 to reduce the negative pressure inside the lower washing device and the water kettle 14.

In order to improve the clothing stain cleaning efficiency of the clothing stain cleaning device of this embodiment, the clothing stain cleaning device further includes a spraying component adapted to be located below the clothing fabric 16 stain.

Please refer to FIG. 1 and FIG. 5, the spray assembly includes a gas delivery tube 28 adapted to penetrate the outer tube 6 from the outside of the side wall of the outer tube 6 to extend into the inner cavity of the outer tube 6, and extend into the outer tube 6.

The side wall, in other words, the pipe wall of the throat pipe 31) and the suction pipe 30 which is in communication with the throat pipe 31 and is suitable for being inserted into the proximal end of the pot cavity of the kettle 14. Moreover, a horn-shaped nozzle 32 is arranged at the mouth of the throat 31 suitable for facing the end of the clothing fabric 16. The inner diameter of the throat pipe 31 is smaller than the inner diameter of the gas pipe 28.

Specifically, the length, width, and depth of the internal cavity of the gas storage tank 29 are larger than the diameter of the pipe hole of the gas pipe 28. One end of the gas pipe 28 penetrates the pipe wall of the outer pipe 6 and the other end is connected to the gas storage. The tank 29 communicates, and the opening of the gas storage tank 29 communicates with the throat 31. A nozzle 32 is arranged at the mouth of the throat 31 which is suitable for facing the end of the clothing fabric 16. This structure allows the air outside the lower washing machine to pass through the air pipe. 28. The gas storage tank 29 and the throat 31 are sprayed from the nozzle 32. The throat 31 communicates with one end of the suction pipe 30. The other end of the suction pipe 30 is located in the kettle 14 and the port is close to the bottom of the kettle 14. . When the air is sucked against the suction pipe 9 with an air suction pump, a large amount of air enters the gas storage tank 29 from the outside of the lower washing machine through the gas pipe 28, and then passes through the throat 31 at high speed and is ejected from the horn-shaped nozzle 32. The air passing through the throat 31 at high speed will cause the air pressure in the throat 31 to be much lower than the pressure in the lower washing device and the water receiving pot 14, which will cause the suction pipe 30 to have a siphon effect and suck the detergent or water in the water receiving pot 14. The throat 31 is also sprayed from the horn-shaped nozzle 32, and the sprayed detergent or water is sprayed onto the clothing fabric 16 to strongly clean the clothing fabric 16.

The specific implementation manner of the clothing stain cleaning device of this embodiment is:

In this embodiment, a two-stage sealing ring (ie, a large sealing ring 4 and a small sealing ring 5 inlaid) is taken as an example. When washing with detergent, first place the stained side of the clothing cloth 16 downward, and point the stain at the device. At the center of the small sealing ring 5 on the lower washing tool, the upper washing tool is docked with the lower washing tool, and the clothes are clothed by the magnetic attraction of the permanent magnet 13 on the lower washing tool to the bearing block 3 on the upper washing tool. 16 is clamped between the small sealing ring 5 of the upper washing tool and the small sealing ring 5 of the lower washing tool. Add an appropriate amount of detergent into the tank 1, and then use the suction pump to pump air toward the suction pipe 9 to create a negative pressure inside the lower washing device and the kettle 14. The negative pressure accelerates the detergent in the tank 1 to pass through The clothing cloth 16 rinses off the stains on the clothing cloth 16, and the detergent passing through the clothing cloth 16 flows through the outer pipe 6, the drain pipe 11, and finally flows into the pot cavity of the kettle 14.

After the washing of the detergent is completed, it needs to be rinsed with clean water. At this time, the upper washing tool is removed and the clothing fabric 16 is removed. It can be seen that a sealing ring with a smaller diameter than the sealing ring 5 facing the clothing fabric 16 is left on the clothing fabric 16 Slightly larger stained wet spots of detergent, drain the detergent in the kettle 14. In order to effectively remove the detergent for rinsing, remove the small sealing ring 5 on the upper and lower washing tools, and then align the wet spot of the detergent on the clothing fabric 16 with the center of the large sealing ring 4 installed on the lower washing tool. And the upper washing device and the lower washing device are docked again to clamp the clothing fabric 16. Then, add an appropriate amount of water to the tank 1 and use the suction pump to pump air toward the suction pipe 9 to create a negative pressure inside the lower washing device and the kettle 14. The negative pressure accelerates the water in the tank 1 through the clothing fabric. 16 and rinse the detergent off the clothing fabric 16. Because the inner diameter of the sealing ring of the large sealing ring 4 facing the clothing fabric 16 is larger than the diameter of the wet spot of the detergent on the clothing fabric 16, the water can effectively rinse the detergent on the clothing fabric 16 during rinsing, thereby achieving a thorough rinsing effect.

During the washing process of the detergent or clean water, when an air pump is used to evacuate the air suction pipe 9, a large amount of air enters the air storage tank 29 from the outside of the lower washing machine through the air pipe 28, and then passes through the throat 31 at high speed and from The horn-shaped nozzle 32 ejects. The air passing through the throat 31 at high speed will cause the air pressure in the throat 31 to be much lower than the pressure inside the lower cavity and the kettle cavity of the kettle 14, so that the suction pipe 30 will have a siphon effect, and the detergent in the kettle 14 will be received. Or the clean water is sucked into the throat 31 and sprayed from the horn-shaped nozzle 32, and the sprayed detergent or clean water is sprayed on the clothing fabric 16 to achieve strong cleaning of the clothing fabric 16. Therefore, the spray component designed in this embodiment can greatly improve For the washing and rinsing efficiency of clothing fabrics.

Example 3:

Please refer to FIG. 5 and FIG. 6. On the basis of the clothing stain cleaning device of Embodiment 2, the bottom end portion of the gas storage tank 29 of the clothing stain cleaning device provided in this embodiment is adapted to store and store A micro-hole 33 penetrating the inner cavity of the gas tank 29.

The pore diameter of the micropore 33 designed in this embodiment may be designed to be a small pore diameter. A small amount of detergent or water is sucked into the throat 31 through the suction pipe 30, and a small amount will enter the gas storage tank 29. The micro-holes 33 can discharge detergent or water in the air storage tank 29.

Example 4:

Please refer to FIG. 6 and FIG. 7. On the basis of the clothing stain cleaning device of Embodiment 3, the tank wall of the gas storage tank 29 of the clothing stain cleaning device provided in this embodiment is hinged with a A shielding component for shielding the micro-hole 33 outside the tank.

Specifically, the shielding assembly includes a rotating shaft 36 that is rotationally connected to the tank wall of the gas storage tank 29, a swing rod 34 that is fixedly connected to one end of the rotating shaft 36 outside the tank of the gas storage tank 29, and a swing rod 34 that is connected to the other end of the swing rod 34. A baffle 35 adapted to cover the micro-holes 33. The rotating shaft 36 may be optionally connected to the tank wall by using, for example, but not limited to, a rotary bearing. The swing lever 34 can be fixedly connected to the rotating shaft 36 by welding. The baffle 35 can be connected to the swing lever 34 by welding.

One end of the swing lever 34 is connected to the baffle 35, and the other end of the swing lever 34 is hinged to the outer wall of the gas storage tank 29 through a rotating shaft 36, so that the swing lever 34 and the baffle 35 can swing around the gas storage tank 29. When the baffle plate 35 is swung to the lower position, the surface of the baffle plate 35 facing the micropores 33 blocks the aperture of the micropores 33, and the surface is not perpendicular to the axis of the micropores 33.

The working principle of this embodiment is: when the baffle 35 is swung counterclockwise to the lower position (see FIG. 7), that is, when the baffle 35 is swung below the micro hole 33, the The surface blocks the orifice of the micro-hole 33, preventing air from being ejected from the micro-hole 33, causing the air pressure in the gas storage tank 29 to rise, and the speed of the airflow flowing through the throat pipe 31 to increase. In addition, because the surface of the baffle 35 facing the micro-hole 33 is not perpendicular to the axis of the micro-hole 33, when the air in the micro-hole 33 hits the surface of the baffle 35 which is not perpendicular to the axis of the micro-hole 33, The plate 35 generates a tangential thrust, causing the baffle 35 and the swing lever 34 to swing in a clockwise direction (see FIG. 6). When the baffle 35 leaves the orifice of the micro-hole 33, the micro-hole 33 resumes air jetting again, the air pressure in the gas storage tank 29 decreases, and the speed of the air flow through the throat pipe 31 decreases. Under the action of gravity, the baffle 35 and the swing lever 34 swing in the counterclockwise direction again, blocking the orifice of the micro-hole 33 again, the air pressure in the gas storage tank 29 rises again, and flows through the throat 31 The speed of the airflow accelerated again. The reciprocating cycle of the baffle 35 and the swing lever 34 pulsates the velocity of the airflow flowing through the throat pipe 31, and the impact force of the detergent or water sprayed on the clothing fabric 16 also changes pulses, thereby improving the cleaning effect on the clothing fabric 16.

Example 5:

Please refer to FIG. 6 and FIG. 7. On the basis of the clothing stain cleaning device of Embodiment 4, the spray assembly of the clothing stain cleaning device provided in this embodiment further includes an inner portion of the gas storage tank 29 and one end and A part of the connecting plate 38 fixed to the inner cavity of the gas storage tank 29 through the rotation shaft 36 and a valve plate fixed to the other end of the connecting plate 38 and adapted to block the gas passage of the opening of the gas storage tank 29 and the throat 31 37. Here, in order to make the valve plate 37 form a barrier between the opening of the gas storage tank 29 and the throat 31, the shape design of the valve plate 37 is adapted to the shape of the opening of the gas storage tank 29, and the valve plate here 37 is to block the opening of the gas storage tank 29 and the throat 31 during the swinging process with the rotation of the rotating shaft 36. Therefore, the shape of the valve plate 37 can be an arc structure, which can realize the The inner cavity of the gas tank 29 is oscillated to block the opening of the gas storage tank 29. In addition, it should be noted that, in order to make the connecting plate 38 and the swing lever 34 respectively fixed at both ends of the rotating shaft 36 to achieve synchronous movement, the rotating shaft 36 is vertically inserted into the gas storage tank 29 relative to the tank wall of the gas storage tank 29, that is, when the storage When the gas tank 29 is placed horizontally, the rotating shaft 36 is disposed along the horizontal direction. Optionally, the connecting plate 38 and the rotating shaft 36 are fixedly connected to each other by welding, and the valve plate 37 is optionally fixed to the connecting plate 38 by welding. The swing of the swing lever 34 and the baffle 35 around the gas storage tank 29 can drive the link plate 38 and the valve plate 37 to synchronously swing through the rotating shaft 36.

The working principle and beneficial effects of this embodiment: When the baffle plate 35 is swung below the microhole 33 in a counterclockwise direction (see FIG. 7), the orifice of the microhole 33 is blocked to cause the inside of the gas storage tank 29 As the air pressure increases, the speed of the air flow through the throat 31 increases. When the baffle 35 leaves the orifice of the micro-hole 33 and swings clockwise to the upper position (see FIG. 6), the micro-hole 33 resumes jetting outward, and at the same time, the valve plate 37 swings synchronously with the rotating shaft 36 At the upper position, at this time, the valve plate 37 blocks the passage of air from the gas storage tank 29 to the throat pipe 31, so that the speed of the airflow flowing through the throat pipe 31 is greatly reduced. When the baffle plate 35 swings in the counterclockwise direction again under the action of gravity, the valve plate 37 also swings in the counterclockwise direction to leave the upper position synchronously. The speed of the airflow of the throat pipe 31 is greatly increased. The swing lever 34 and the baffle 35 drive the reciprocating cycle of the link plate 38 and the valve plate 37, so that the velocity of the air flow passing through the throat pipe 31 has a strong pulsation, and the impact force of the detergent or water sprayed on the clothing fabric 16 also produces a strong The pulse changes, thereby further improving the cleaning effect on the clothing fabric 16. It should be noted that the “counterclockwise” and “clockwise” directions referred to here are directions defined by the illustration as an example.
