[0030] As attached Figure 2 As shown in the coordinate system, the X-axis is defined as the front-back direction, the Y-axis as the left-right direction, and the Z-axis as the up-down direction. It is understood that the above coordinate system is intended to illustrate the approximate positional, connection, or movement relationships of the components, and does not imply that the components in this invention must be strictly set or connected according to the above coordinate system.

[0031] Handheld fabric cleaning devices are used to clean items that are difficult to machine wash, such as sofas, mattresses, and curtains. The working principle is to spray an aqueous solution mixed with detergent onto the dirty areas of the items, and then repeatedly scrub them with the brush head on the main body of the machine. Finally, the stains and water on the items are sucked into the water tank to complete the cleaning.

[0032] The water tank is an important component of handheld fabric cleaning devices. To facilitate handheld operation, the water tank is usually small in size. During use, the wastewater collected in the water tank is easily shaken and leaks out from the opening of the water tank, which can easily lead to secondary contamination of the items to be cleaned. In severe cases, it can cause a short circuit of the entire machine, which has certain limitations.

[0033] Combined with appendix Figure 1 and attached Figure 2 The handheld fabric cleaning device proposed in this utility model has a water tank including a cover plate 10, a first housing 20 and a second housing 30. The cover plate 10, the first housing 20 and the second housing 30 are connected in sequence along the vertical direction. The first housing 20 and the second housing 30 are connected and cooperate to form a liquid collection chamber 31. The cover plate 10 includes a first opening 11, which is connected to the liquid collection chamber 31. The main body of the device is connected to the first opening 11. Wastewater collected during the cleaning process of the main body enters the liquid collection chamber 31 through the first opening 11. A guide 40 is installed at the first opening 11.

[0034] As attached Figure 4 As shown, the guide member 40 includes a first guide plate 41 and a second guide plate 42. The first guide plate 41 has an inlet hole 411, which is a through hole that penetrates the thickness direction of the first guide plate 41. The second guide plate 42 is provided with one-way components. The number and position of the one-way components correspond to the number and position of the inlet holes 411. The one-way components ensure that sewage can only enter the collection chamber 31 through the first opening 11, and the sewage collected in the collection chamber 31 cannot flow out from the first opening 11.

[0035] To prevent sewage from leaking out, users usually need to adjust the angle of the whole machine to keep the water tank level. If the water tank is tilted forward, sewage can easily leak out from the first opening 11 of the cover plate 10. With the setting of the guide 40, even if the user tilts the water tank forward during transportation or use, sewage will not flow back to the main body of the machine from the first opening 11, thus avoiding sewage leakage onto the items to be cleaned and solving the problem of easy secondary pollution.

[0036] In one example scheme, combined with appendix Figure 4 and attached Figure 5 The unidirectional component includes a baffle 421 and a guide hole 422. The guide hole 422 is formed on the second guide plate 42 and is a through hole that penetrates the thickness direction of the second guide plate 42. The radial dimension of the guide hole 422 is larger than the radial dimension of the inlet hole 411, and the number and position of the guide holes 422 correspond to the number and position of the inlet holes 411. The baffle 421 is movably disposed on the second guide plate 42, and the radial dimension of the baffle 421 is larger than the radial dimension of the inlet hole 411. The baffle 421 has a first state and a second state relative to the guide hole 422.

[0037] Appendix Figure 4 This is a schematic diagram of the baffle 421 in its first state. (See attached diagram) Figure 5 This is a schematic diagram of the baffle 421 in the second state. When the baffle 421 is in the first state, the position of the baffle 421 corresponds to the position of the inlet hole 411, and the guide hole 422 is closed. At this time, no sewage enters the inlet hole 411. When the baffle 421 is in the second state, the baffle 421 rotates relative to the guide hole 422 to the side away from the first guide plate 41, and the guide hole 422 opens. At this time, sewage enters the inlet hole 411 and enters the liquid collection chamber 31 through the guide hole 422.

[0038] Only when sewage enters through the inlet 411 will the baffle 421 rotate under the force of the sewage and open the guide hole 422. When the water tank shakes, even if the sewage in the collection chamber 31 moves to the guide member 40, the outward rotation of the baffle 421 will be blocked by the first guide plate 41 due to the large size of the baffle 421, so the guide hole 422 cannot be opened. The sewage already collected in the collection chamber 31 cannot pass through the guide member 40 and therefore cannot leak out from the inlet 411.

[0039] Optionally, the baffle 421 is movably disposed within the guide hole 422, and the baffle 421 can rotate in the guide hole 422 toward the side away from the first guide plate 41. Part of the baffle 421 is connected to the hole wall of the guide hole 422, and the other part is in contact with the hole wall of the guide hole 422 but not connected. The baffle 421 can be flipped relative to its connection with the guide hole 422 under the force of sewage, but it is not disconnected from the hole wall of the guide hole 422. When the force of sewage disappears (i.e. there is no sewage at the inlet hole 411), the baffle 421 returns to the first state, and the guide hole 422 is closed.

[0040] Optionally, the baffle 421 is movably disposed on the side of the second guide plate 42 away from the first guide plate 41, and the position of the baffle 421 corresponds to the position of the guide hole 422, so that the baffle 421 in the first state can block the guide hole 422. The radial dimension of the baffle 421 is greater than or equal to the radial dimension of the guide hole 422. The baffle 421 is partially fixedly connected to the second guide plate 42. The baffle 421 can be flipped relative to its connection with the second guide plate 42 under the force of sewage, but it does not break the connection with the second guide plate 42. Optionally, the guide member 40 and the cover plate 10 can be fixedly connected by adhesive backing, or by detachable connection methods such as snap-fit, screw connection, or sliding groove connection.

[0041] In one example scheme, as shown in the appendix Figure 3As shown, the cover plate 10 includes a second opening 12. One of the first opening 11 and the second opening 12 is located at the front end of the cover plate 10, and the other is located at the rear end of the cover plate 10. The second opening 12 is connected to the liquid collection chamber 31. A gas-liquid separator 14 is installed at the second opening 12 to realize gas-liquid separation in the liquid collection chamber 31. The gas in the liquid collection chamber 31 can be discharged from the liquid collection chamber 31 through the gas-liquid separator 14 and the second opening 12.

[0042] The gas-liquid separator 14 prevents liquid in the collection chamber 31 from being discharged through the second opening 12, thus avoiding liquid from entering the motor or other components of the main body of the machine through the second opening 12, eliminating safety hazards. Even if the user tilts the whole machine backward during handling or use, there will be no water leakage at the second opening 12, ensuring a good user experience. Especially when cleaning tall items such as curtains, the whole machine can be easily lifted without worrying about water leakage. By venting gas through the second opening 12, it can prevent sewage in the collection chamber 31 from flowing back to the first opening 11 due to unstable gas pressure, reducing the fluctuation of the liquid level in the collection chamber 31 during handling or use.

[0043] Optionally, the gas-liquid separator 14 uses a waterproof and breathable membrane. Because its gap density is larger than that of air molecules but smaller than that of water molecules, it can prevent liquid leakage while allowing air to pass through. Gas in the liquid collection chamber 31 can be discharged through the waterproof and breathable membrane to ensure stable gas pressure within the liquid collection chamber 31. The waterproof and breathable membrane can be adhered to the second opening 12 using adhesive.

[0044] Optionally, the gas-liquid separator 14 may be a waterproof and breathable valve, which may be installed at the second opening 12 by screwing or other fixing methods.

[0045] In one example scheme, as shown in the appendix Figure 4 As shown, the cover plate 10 includes a partition 13, which is disposed between the first opening 11 and the second opening 12. The partition 13 can separate the first opening 11 and the second opening 12 in the front-back direction, which can prevent sewage entering from the first opening 11 from splashing to the second opening 12. It can work with the gas-liquid separator 14 to achieve good gas-liquid separation.

[0046] In one example, the first housing 20 includes a mounting groove 21 that extends vertically through the first housing 20. A cover plate 10 is detachably mounted on the mounting groove 21. The mounting groove 21 communicates with the liquid collection chamber 31. By removing and installing the cover plate 10, the user can clean the inside of the liquid collection chamber 31 and easily pour out the sewage in the liquid collection chamber 31.

[0047] Optionally, the aforementioned spacer 13 extends in the vertical direction, and its lower end extends into the mounting groove 21.

[0048] Optionally, the first housing 20 and the second housing 30 can be connected as one unit by ultrasonic welding or adhesive application, or they can be detachably connected by screws for easy cleaning.

[0049] In one example scheme, combined with appendix Figure 2 and attached Figure 3 A fixing groove 15 is provided on the lower outer periphery of the cover plate 10, and a fixing protrusion 22 is provided on the groove wall of the mounting groove 21. When the cover plate 10 is connected to the first housing 20, the fixing protrusion 22 is engaged in the fixing groove 15. This arrangement can realize the quick positioning and installation of the cover plate 10 and the first housing 20.

[0050] Optionally, a sealing element is provided between the cover plate 10 and the first housing 20. More specifically, a sealing element is provided between the cover plate 10 and the mounting groove 21. The sealing element makes the cover plate 10 and the mounting groove 21 interference fit, which prevents water and air leakage at the connection between the cover plate 10 and the first housing 20, and helps to ensure the user's experience.

[0051] In one example scheme, as shown in the appendix Figure 4 As shown, the guide member 40 also includes a base 43, which is located on the side of the second guide plate 42 away from the first guide plate 41. The first guide plate 41 and the second guide plate 42 are installed at the first opening 11 through the base 43, and the first guide plate 41 is located on the side of the second guide plate 42 away from the base 43. A through groove 431 is provided on the base 43, and the first opening 11 is connected to the liquid collection chamber 31 through the through groove 431.

[0052] Optionally, a support edge 432 protrudes from the wall of the through groove 431. The thickness of the support edge 432 is smaller than the depth of the through groove 431, that is, the support edge 432 is recessed into the through groove 431. The dimensions of the through groove 431 match the second guide plate 42. When the second guide plate 42 is installed, the second guide plate 42 is embedded in the through groove 431. The support edge 432 contacts the second guide plate 42 and provides support. The through groove 431 and the support edge 432 match to achieve quick positioning and installation of the second guide plate 42 and the base 43. The first guide plate 41 is placed on the second guide plate 42 to complete the installation and connection of the guide member 40.

[0053] When the machine needs to discharge sewage into the water tank, the sewage enters the inlet hole 411 of the first guide plate 41. Since the inlet hole 411 corresponds to the position of the baffle 421, the sewage exerts force on the baffle 421, causing the baffle 421 to move and the guide hole 422 to open. The sewage enters the collection chamber 31 through the guide hole 422 and the through groove 431, thus realizing the collection of sewage. After the sewage collection is completed, the baffle 421 is reset and the guide hole 422 is closed.

[0054] When the cleaning device is transported or used, if the sewage causes violent shaking in the collection chamber 31, since the radial dimension of the baffle 421 is larger than the radial dimension of the inlet hole 411, even if some sewage reaches the second guide plate 42 and applies force to the baffle 421, the baffle 421 cannot move outward. The sewage cannot enter the guide hole 422 and the inlet hole 411 through the baffle 421, thus avoiding the problem of sewage leakage. Users can use it with confidence.

[0055] Optionally, the first guide plate 41 and the base 43 are connected by ultrasonic welding to clamp and fix the second guide plate 42 between the first guide plate 41 and the base 43, which has good connection quality; the first guide plate 41 and the base 43 can also be detachably connected by a snap-fit ​​structure, screw connection or other means. The detachable connection facilitates subsequent maintenance and disassembly and assembly of the second guide plate 42, and is highly practical.

[0056] Optionally, the second guide plate 42 is made of Teflon sheet, which has good acid and alkali resistance and good corrosion resistance. (See attached...) Figure 2 As shown, the second housing 30 is also provided with a functional cavity 32, which contains an aqueous solution. The aqueous solution can be a mixture of water and detergent. A cavity plate 33 is provided between the functional cavity 32 and the liquid collection cavity 31. The cavity plate 33 is used to separate the functional cavity 32 and the liquid collection cavity 31. The functional cavity 32 is connected to the main body of the machine. The main body of the machine can spray the aqueous solution onto the dirty parts of the items to be cleaned.

[0057] Optionally, the cavity plate 33 is integrally formed with the second housing 30.

[0058] Optionally, the volume of the collection chamber 31 is larger than the volume of the functional chamber 32 to facilitate the collection of impurities and dirt after cleaning. In one example embodiment, combined with the attached... Figure 2 and attached Figure 3 The collection chamber 31 is equipped with at least one buffer member 50, which divides the collection chamber 31 into at least two buffer chambers. The buffer member 50 has a connecting hole 51, which is a through hole for connecting the aforementioned at least two buffer chambers. By dividing the collection chamber 31 into buffer chambers, the collected wastewater is dispersed and stored in each buffer chamber. During the use of the cleaning device, when the water tank shakes with the main body, the buffer member 50 can block the wastewater, preventing it from fluctuating significantly with the main body, reducing the probability of wastewater leakage from the first opening 11, and broadening the applicability of the entire machine.

[0059] Optionally, the buffer 50 is used to divide the liquid collection chamber 31 into at least two buffer chambers in the front-back direction.

[0060] As one possible installation method for the buffer 50, see attached... Figure 3As shown, the cavity walls on the left and right sides of the liquid collection cavity 31 are provided with a retaining plate 311. The two retaining plates 311 on the cavity wall on the same side cooperate to form a retaining groove. The left and right ends of the buffer member 50 are installed in the retaining groove. With this setting, the buffer member 50 can be quickly positioned and installed. The buffer member 50 can be inserted into the retaining groove from top to bottom first, and then the second housing 30 and the first housing 20 can be connected as a whole.

[0061] Understandably, the number of buffer members 50 can be adjusted according to the size of the liquid collection chamber 31. In a preferred embodiment, as shown in the attached diagram... Figure 2 As shown, there are two buffer elements 50, which are spaced apart and arranged in parallel to divide the collection chamber 31 into three buffer chambers to achieve a better effect of eliminating sewage inertia.

[0062] The handheld fabric cleaning device proposed in this utility model uses a water tank. By setting a guide 40 at the first opening 11 of the cover plate 10, and through the cooperation of the first guide plate 41 and the second guide plate 42, the one-way component can ensure that the wastewater collected in the receiving cavity will not leak out from the first opening 11. Whether the user is carrying the whole machine or using the whole machine for cleaning, there will be no limitation on the angle of use of the whole machine. Even if the whole machine is tilted, there will be no problem of wastewater flowing back to the first opening 11 and leaking. It also avoids the problem of secondary pollution of items during the cleaning process, eliminates the safety hazards caused by water leakage, and improves the user experience.

[0063] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
