Description

Technical Field

[0001] This invention relates to the field of window cleaning machine technology, and more particularly to a modular quick-release atomizing water spray system for window cleaning machines. Background Technology

[0002] Existing window cleaning machine atomizing spray systems typically have the atomizing disc fixed to the spray nozzle of the water tank via a cover plate, and the entire disc is integrated inside the machine casing. The power supply for the atomizing disc is usually provided by soldering wires to the main board.

[0003] This structural design has the following drawbacks: First, the way the atomizing plate is assembled with the water tank means that users cannot maintain the atomizing plate themselves after it becomes scaled, clogged, or malfunctions. They must disassemble the entire machine or return it to the factory for repair, which results in a long maintenance cycle and high costs, seriously affecting the user experience. Second, the welded wires are prone to fatigue fracture under the long-term vibration of the window cleaning machine, affecting the reliability of the electrical connection. Summary of the Invention

[0004] The purpose of this invention is to provide a modular quick-release atomizing water spraying system for window cleaning machines, which solves the problems of existing window cleaning machine atomizing water spraying systems, where the atomizing components are fixedly installed inside the machine casing and use a welded power supply method, resulting in users being unable to replace and maintain them themselves and poor electrical connection reliability.

[0005] To achieve the above objectives, the present invention provides a modular quick-release atomizing water spray system for a window cleaning machine, comprising a window cleaning machine upper shell, an outer shell, and a water tank assembly. The water tank assembly is fixedly connected to the outer shell and located inside the outer shell. The upper shell of the window cleaning machine is fixedly connected to the outer shell and located on one side of the outer shell. The system also includes an atomizing component. The atomizing component includes a filter element, an atomizing plate, an atomizing disc, a sealing gasket, a pressure plate, and a power supply component. The water tank assembly has spray holes. The filter element is installed in the spray holes of the water tank assembly. The atomizing disc is fixed to the atomizing plate. The sealing gasket is disposed between the pressure plate and the atomizing plate. The pressure plate is detachably fixed to the water tank assembly by mounting screws and presses the atomizing plate against the water tank assembly, causing the atomizing disc to contact the filter element. When the pressure plate is fixed, the power supply component supplies power to the atomizing disc.

[0006] The filter component includes an absorbent cotton swab and a sealing sleeve. The absorbent cotton swab is installed inside the sealing sleeve, and the sealing sleeve is snapped into the spray hole. One end of the sealing sleeve extends out of the spray hole and abuts against the atomizing plate to form a sealed water path.

[0007] The water tank assembly includes a large water tank, a small water tank, and pipes. The large water tank and the small water tank are connected through the pipes. The large water tank and the small water tank are fixed inside the outer casing. The water spray hole is located on the large water tank, and the power supply component is fixedly installed on the side of the large water tank near the water spray hole.

[0008] The water tank assembly also includes a water tank cap, which is connected to the large water tank and located on one side of the large water tank.

[0009] The power supply component includes an atomizing adapter plate and a spring pin. The atomizing adapter plate is fixedly connected to the large water tank by fixing screws. The spring pin is fixedly connected to the atomizing adapter plate and extends toward the atomizing plate.

[0010] The modular quick-release atomizing water spray system for the window cleaning machine also includes a water spray cover plate, which is detachably connected to the housing and located on the side of the housing near the atomizing component.

[0011] The atomizing plate has mounting holes that mate with the atomizing sheet and penetrate the atomizing plate.

[0012] The atomizing plate also has an installation notch that communicates with the installation hole and is located at the edge of the installation hole; the atomizing sheet has an electrode that passes through the installation notch and is welded and fixed to the atomizing plate.

[0013] This invention discloses a modular quick-release atomizing water spray system for a window cleaning machine. When the atomizing plate becomes scaled or the filter component becomes clogged and needs replacement, firstly, the mounting screws are unscrewed, and the pressure plate, along with the atomizing plate, the atomizing plate, and the sealing gasket, are removed from the water tank assembly. At this time, the power supply component is separated from the atomizing plate, while the filter component remains inside the spray hole. Next, the old atomizing plate and atomizing plate are removed, and a new atomizing plate is fixed onto the new atomizing plate. The pressure plate is then installed, and the sealing gasket is placed. The assembled atomizing assembly is then aligned with the spray hole on the water tank assembly, so that the atomizing plate contacts the filter component, and the contacts on the atomizing plate align with the power supply component. The mounting screws are tightened, and the pressure plate presses the atomizing plate firmly, achieving electrical conductivity between the atomizing plate and the power supply component. Simultaneously, the sealing gasket ensures a water circuit seal. Throughout the replacement process, the user does not need to touch any wires or perform any welding, achieving modular quick-release.

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] First embodiment: Please see Figures 1 to 6 ,in Figure 1 This is a schematic diagram of the overall structure of a modular, quick-release atomizing water spray system used in window cleaning machines. Figure 2 This is a schematic diagram of the water tank assembly installation structure. Figure 3 This is a schematic diagram of the installation structure of the pressure plate. Figure 4 This is a schematic diagram of the atomizing component. Figure 5 This is a schematic diagram of the installation structure of absorbent cotton swabs. Figure 6 This is a structural diagram of the power supply components.

[0024] This invention provides a modular quick-release atomizing water spray system for window cleaning machines, including a window cleaning machine upper shell 1, an outer shell 2, a water tank assembly 3, and an atomizing component 4. The atomizing component 4 includes a filter component 5, an atomizing plate 6, an atomizing sheet 7, a sealing gasket 8, a pressure plate 9, and a power supply component 10. The filter component 5 includes an absorbent cotton swab 12 and a sealing sleeve 13. The water tank assembly 3 includes a large water tank 14, a small water tank 15, a pipe 16, and a water tank rubber cap 17. By designing the atomizing component 4 as an independent module and detachably fixing it to the water tank assembly 3 with mounting screws 11, this invention solves the problems of existing window cleaning machines where the atomizing components are fixedly installed inside the machine casing and powered by welding, resulting in users being unable to replace and maintain them themselves, poor electrical connection reliability, and high maintenance costs. It is understood that the aforementioned solution can be used in cleaning equipment that requires regular maintenance or replacement of the atomizing components.

[0025] In this specific embodiment, the water tank assembly 3 is fixedly connected to the outer shell 2 and located inside the outer shell 2, and the upper shell 1 of the window cleaning machine is fixedly connected to the outer shell 2 and located on one side of the outer shell 2.

[0026] The water tank assembly 3 has a spray hole 24. The filter element 5 is installed in the spray hole 24 of the water tank assembly 3. The atomizing plate 7 is fixed on the atomizing plate 6. The sealing gasket 8 is disposed between the pressure plate 9 and the atomizing plate 6. The pressure plate 9 is detachably fixed to the water tank assembly 3 by mounting screws 11, pressing the atomizing plate 6 against the water tank assembly 3, so that the atomizing plate 7 contacts the filter element 5. When the pressure plate 9 is fixed, the power supply element 10 supplies power to the atomizing plate 7. During normal operation, water in the water tank assembly 3 enters the atomizing plate 7 through the filter element 5. The atomizing plate 7 vibrates at high frequency under the drive of the power supply element 10, atomizing the water and spraying it out. When the atomizing plate 7 is scaled or the filter element 5 is clogged and needs to be replaced, first unscrew the mounting screws 11, and then remove the pressure plate 9 along with the atomizing plate 6. The atomizing plate 6, the atomizing disc 7, and the sealing gasket 8 are removed from the water tank assembly 3 as a whole. At this time, the power supply component 10 is separated from the atomizing plate 6, while the filter component 5 remains inside the spray hole 24. Next, the old atomizing disc 7 and the atomizing plate 6 are removed, and the new atomizing disc 7 is fixed onto the new atomizing plate 6. The pressure plate 9 is then installed, and the sealing gasket 8 is placed. The assembled atomizing assembly 4 is then aligned with the spray hole 24 on the water tank assembly 3, so that the atomizing disc 7 contacts the filter component 5, and the contacts on the atomizing plate 6 are aligned with the power supply component 10. The mounting screws 11 are tightened, and the pressure plate 9 presses the atomizing plate 6 firmly. The atomizing plate 6 and the power supply component 10 are electrically connected, while the sealing gasket 8 ensures the water circuit is sealed. During the entire replacement process, the user does not need to touch any wires or weld, achieving modular quick disassembly.

[0027] Secondly, the absorbent cotton swab 12 is installed inside the sealing sleeve 13, and the sealing sleeve 13 is snapped into the spray hole 24. One end of the sealing sleeve 13 extends out of the spray hole 24 and abuts against the atomizing plate 7 to form a sealed water channel. The absorbent cotton swab 12, as a porous absorbent component, fills the inside of the sealing sleeve 13. One end is connected to the water channel inside the water tank assembly 3, and the other end is opposite to the microporous surface of the resonant substrate of the atomizing plate 7. When the pressure plate 9 is pressed, the sealing sleeve 13 undergoes elastic deformation, which not only fills the gap between the atomizing plate 7 and the spray hole 24 to prevent water leakage, but also presses the absorbent cotton swab 12 against the back of the atomizing plate 7, so that the absorbent cotton swab 12 is in close contact with the atomizing plate 7. The absorbent cotton swab 12 uses capillary action to evenly and stably absorb and conduct water from the water tank to the microporous surface of the atomizing plate 7. On the one hand, it filters impurities in the water and prevents the atomizing plate 7 from clogging. On the other hand, through its water storage and conduction characteristics, it effectively buffers water pressure fluctuations and avoids static dripping of the atomizing plate 7 due to excessive water pressure.

[0028] Furthermore, the material of the absorbent cotton stick 12 can be replaced with other porous absorbent materials, such as sintered fiber, high-density sponge, etc.

[0029] Meanwhile, the large water tank 14 and the small water tank 15 are connected through the pipe 16, and the large water tank 14 and the small water tank 15 are fixed inside the outer shell 2; the water spray hole 24 is provided on the large water tank 14, and the power supply component 10 is fixedly installed on the side of the large water tank 14 near the water spray hole 24.

[0030] In addition, the water tank cap 17 is connected to the large water tank 14 and is located on one side of the large water tank 14.

[0031] The spray nozzle 24 is directly located at the bottom of the large water tank 14, and the filter component 5 is installed inside the spray nozzle 24 of the large water tank 14, drawing water directly from inside the large water tank 14; the water tank cap 17 is detachably connected to the large water tank 14, and is usually sealed by a snap or thread, located at the top or side of the large water tank 14, used to seal the water inlet of the large water tank 14, facilitating water filling by the user while preventing water leakage during operation.

[0032] Second embodiment: Based on the first embodiment, please refer to Figures 1 to 6 The power supply component 10 in this embodiment includes an atomizing adapter plate 18 and a spring pin 19, and the modular quick-release atomizing water spray system for the window cleaning machine also includes a water spray cover plate 20.

[0033] In this specific embodiment, the atomizing adapter plate 18 is fixedly connected to the large water tank 14 by fixing screws 23; the spring pin 19 is fixedly connected to the atomizing adapter plate 18 and extends towards the atomizing plate 6; the atomizing plate 6 is provided with contacts corresponding to the spring pins 19 one by one. When the pressure plate 9 is fixed to the large water tank 14 by the mounting screws 11, the spring pin 19 and the contacts on the atomizing plate 6 elastically abut against each other, forming a stable electrical path; the method of elastic contact between the spring pin 19 and the conductive pad completely replaces the traditional soldering wire, which not only eliminates the risk of fatigue fracture of the wire under vibration environment, but also allows the atomizing component 4 to achieve electrical connection switching without any tools during disassembly and installation, further improving the convenience of quick disassembly.

[0034] Furthermore, in this embodiment, the spring pin 19 can be replaced by a resilient metal contact spring.

[0035] The spray cover 20 is detachably connected to the outer casing 2 and is located on the side of the outer casing 2 closer to the atomizing component 4. The spray cover 20 can be fixed to the outer casing 2 by means of clips or screws to protect the internal atomizing component 4 from the intrusion of external foreign objects, and at the same time guide the spray direction to ensure that the water mist can be accurately sprayed onto the cleaning area of ​​the window cleaning machine. When the user needs to replace the atomizing component 4, the spray cover 20 is removed first to expose the atomizing component 4, and then the mounting screws 11 are unscrewed to perform the replacement operation.

[0036] Secondly, the atomizing plate 6 has a mounting hole 21, which mates with the atomizing sheet 7 and penetrates the atomizing plate 6.

[0037] Meanwhile, the atomizing plate 6 also has an installation notch 22, which communicates with the installation hole 21 and is located at the edge of the installation hole 21; the atomizing sheet 7 has an electrode, which passes through the installation notch 22 and is welded and fixed to the atomizing plate 6.

[0038] The atomizing plate 7 has two electrodes, namely a first electrode and a second electrode. During assembly, the resonant substrate of the atomizing plate 7 is oriented towards the back of the atomizing plate 6, and the microporous surface of the atomizing plate 7 is oriented towards the back of the atomizing plate 6. The atomizing plate 7 is then embedded in the mounting hole 21. The first electrode of the atomizing plate 7, as a protruding electrode lead, passes through the mounting notch 22 to the front of the atomizing plate 6. The atomizing plate 7 is then rotated so that the first electrode is aligned with the dedicated pad on the front of the atomizing plate 6 and soldered in place. Subsequently, the atomizing plate 6 is flipped over, and the second electrode of the atomizing plate 7 is soldered to the corresponding dedicated pad on the back of the atomizing plate 6.

[0039] The modular quick-release atomizing water spray system for window cleaning machines of the present invention, by designing the atomizing component 4 as an independent module detachably connected to the water tank assembly 3, combined with the integrated sealing structure of the filter component 5, the elastic contact method of the power supply component 10, and the embedded welding structure of the atomizing plate 7 and the atomizing plate 6, achieves user-level quick-release maintenance. Users do not need any tools; they only need to remove the spray cover 20 and loosen the mounting screws 11 to remove and replace the entire atomizing component 4. The entire process requires no contact with wires or welding operations, completely solving the pain point of traditional window cleaning machine atomizing components being fixed inside the casing, which prevents users from maintaining them themselves and necessitates factory repairs. This significantly reduces the maintenance threshold and cost, and improves the user experience. Simultaneously, through the… The elastic contact between the spring pin 19 and the atomizing plate 6 replaces the traditional welded lead wire, which not only eliminates the risk of fatigue breakage of the wire under long-term vibration in the window cleaning machine, but also ensures stable electrical conduction after repeated insertion and removal. The double-sided welding structure between the atomizing plate 7 and the atomizing plate 6 makes the atomizing plate 7 firmly embedded in the atomizing plate 6, further enhancing the vibration resistance of the atomizing unit and the reliability of the electrical connection. In addition, the sealing sleeve 13 is snapped into the water spray hole 24 and elastically abuts against the atomizing plate 7 to form a reliable sealed water channel, eliminating the risk of water leakage. The absorbent cotton swab 12 is filled in the sealing sleeve 13 and guides water evenly through capillary action, which not only filters impurities in the water to prevent the atomizing plate 7 from clogging, but also buffers water pressure fluctuations to avoid static dripping, significantly improving the stability and service life of the atomizing system.

[0040] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
