Description

[Technical Field]

[0002] This utility model relates to the field of cleaning equipment technology, and in particular to a powerful suction window cleaning machine. [Background Technology]

[0004] Window cleaning robots are a type of smart home appliance. Utilizing artificial intelligence, they automatically detect the edges and corners of windows and plan a cleaning path. Typically, the robot uses its own suction to adhere to the glass, pulling a cloth at the bottom to wipe away dirt. After cleaning, it returns to its initial position for easy removal. Fan-driven window cleaning robots use an internal fan to create a pressure difference between the inside and outside of the glass, thus adhering to it. This adsorption principle has slightly less stringent requirements for the medium; a flat surface is sufficient. Current technology often uses a single-duct air outlet, which restricts airflow at the outlet, reducing the amount of air entering the inlet and consequently decreasing the robot's suction power, potentially causing it to fall during operation. [Utility Model Content]

[0006] To overcome the problem of reduced suction power in window cleaning machines, which could cause them to fall during operation, this invention aims to provide a high-suction window cleaning machine. This invention is achieved through the following technical solution:

[0007] A high-powered window cleaning machine includes a base assembly for cleaning dirt, the base assembly being connected to a fan device for fluid flow, the base assembly and the fan device forming a first air inlet channel and a second air inlet channel for external fluid to enter the base assembly and the fan device, the fluid flowing into the fan device after passing through the first air inlet channel and the second air inlet channel, the fan device having a first air outlet channel and a second air outlet channel communicating with the first air outlet channel, so that when the fan device is working, the first air inlet channel and the second air inlet channel can quickly draw out air to form a strong negative pressure.

[0008] As described above, in a high-powered window cleaning machine, the first air outlet channel and the second air outlet channel are distributed in a vortex shape with the fan device as the center.

[0009] As described above, a high-powered window cleaning machine has a first air outlet at the end of the first air outlet channel and a second air outlet at the end of the second air outlet channel. The first air outlet and the second air outlet are respectively located on both sides of the fan device to balance the forces on both sides.

[0010] As described above, a high-powered window cleaning machine includes a fan assembly for providing power to flow fluid. A fan housing is connected to the outer periphery of the fan assembly. The fan housing includes a fan bottom shell connected to a base assembly and a fan top cover connected to the fan bottom shell for sealing the fan device. Silicone foam for enhanced sealing is connected between the fan top cover and the fan bottom shell.

[0011] As described above, in a high-powered window cleaning machine, the upper cover of the fan is provided with a first stop, and the bottom shell of the fan is provided with a second stop that mates with and connects to the first stop.

[0012] In the aforementioned high-powered window cleaning machine, the first stop is a first concave stop, and the second stop is a first convex stop. The first concave stop and the first convex stop are matched and connected to jointly seal the first air outlet channel and the second air outlet channel.

[0013] As described above, a high-powered suction window cleaning machine includes a base assembly comprising a base housing, the base housing being connected to a rotating suction cup for adsorbing onto an object, and a first air inlet and a second air inlet respectively provided between the base housing and the rotating suction cup for fluid to flow into the first air inlet channel and the second air inlet channel.

[0014] As described above, a high-powered window cleaning machine has a base fan housing that is connected to and cooperates with a fan base housing. The fan base housing has a third stop, and the base fan housing has a fourth stop that is connected to and cooperates with the third stop.

[0015] In the aforementioned high-powered window cleaning machine, the third stop is a second concave stop, and the fourth stop is a second convex stop. The second concave stop and the second convex stop are matched and connected to jointly seal the first air inlet channel and the second air inlet channel.

[0016] As described above, a high-powered window cleaning machine has a fan inlet on its bottom casing that allows fluid from the first and second air inlets to enter the fan device.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By designing a first air outlet channel and a second air outlet channel, the limitation of low airflow rate in the same time is eliminated. The first air outlet channel and the second air outlet channel are connected in a vortex shape to reduce the fluid resistance during discharge, which is conducive to the rapid flow of fluid in the air inlet channel, so that the base assembly has a strong adsorption force to adhere to the object.

[0019] 2. When the machine is running, the machine draws water into the air duct assembly by rotating the disc. The entire air duct and the fan cover are fully pre-pressed and sealed with silicone foam, eliminating the risk of water overflow and allowing water to be discharged from the air outlet intact. The silicone foam between the first stop and the second stop prevents water inside the fan housing from leaking out of the fan housing and burning out the circuit.

[0020] 3. The air inlet and outlet of the window cleaning machine are set in the same direction, with the outlet facing the glass working surface. The exhaust air is blown towards the glass working surface, which allows the glass surface, which is still moist after cleaning, to dry quickly, reducing the adsorption of dust and lint. It can also blow away the adsorbed dust and lint, improving the cleaning efficiency and effect of the glass surface.

[0032] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0033] See also Figures 1 to 8 A high-powered window cleaning machine includes a base assembly 1 for cleaning dirt. The base assembly 1 is connected to a fan device 2 for fluid flow. The base assembly 1 and the fan device 2 form a first air inlet channel 301 and a second air inlet channel 302 for external fluid to enter the base assembly 1 and the fan device 2. After passing through the first air inlet channel 301 and the second air inlet channel 302, the fluid flows into the fan device 2. The fan device 2 has a first air outlet channel 51 and a second air outlet channel 52 that is connected to the first air outlet channel 51. When the fan device 2 is working, the first air inlet channel 301 and the second air inlet channel 302 can quickly draw out air to form a high negative pressure. The design of the first air outlet channel 51 and the second air outlet channel 52 utilizes the principle of fluid dynamics to enable the base assembly 1 to generate sufficient negative pressure, thereby having a strong suction force and being able to firmly adhere to the surface of the object. The fluid channel design can reduce airflow turbulence and noise, making the window cleaning machine quieter during operation.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the first air outlet channel 51 and the second air outlet channel 52 are arranged in a vortex shape with the fan device 2 as the center. This helps to reduce the fluid resistance when the fluid is discharged. In the first air inlet channel 301 and the second air inlet channel 302, the fluid flows rapidly, which accelerates the extraction of air between the object and the base assembly, forming a pressure difference with the atmosphere. A negative pressure is formed between the object and the base assembly, which strengthens the adsorption force of the base assembly.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the first air outlet 51 is provided with a first air outlet 511 at its end, and the second air outlet 52 is provided with a second air outlet 521 at its end. The first air outlet 511 and the second air outlet 521 are respectively provided on both sides of the fan device 2 to balance the forces on both sides. By providing two independent air outlets, the direction and flow rate of the airflow can be better controlled. If one air outlet fails or is blocked, the other air outlets can still continue to work, ensuring the continuous operation of the entire air outlet channel.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the fan device 2 includes a fan assembly 21 for providing power to flow fluid. The fan assembly 21 is connected to a fan housing 22 on its outer periphery. The fan housing 22 includes a fan bottom shell 221 connected to the base assembly 1 and a fan top cover 222 connected to the fan bottom shell 221 for sealing the fan device 2. The fan assembly 21 provides strong power to ensure that the fluid can flow quickly. The design of the fan housing 22 makes the entire fan device 2 compact in structure, occupies little space, and is easy to integrate into a window cleaning machine.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, a silicone foam 8 for enhanced sealing is connected between the fan top cover 222 and the fan bottom shell 221. The silicone foam is soft and elastic, able to conform well to irregular surfaces, maintaining a good sealing effect even under pressure changes, and effectively blocking moisture, dust, and other fine particles, providing excellent waterproof and dustproof performance. The fan top cover 222 has a first stop 2221, and the fan bottom shell 221 has a second stop 2222 that mates with the first stop 2221. The silicone foam 8 is located at the first stop 2221. Between the first stop 2221 and the second stop 2222, the first stop 2221 is a first concave stop and the second stop 2222 is a first convex stop. The first concave stop and the first convex stop are matched and connected to seal the connection gap between the fan cover 222 and the fan bottom shell 221, preventing water inside the fan shell from leaking out of the fan shell and burning out the circuit. The silicone foam has good elasticity and weather resistance, and can maintain the sealing effect in various environments. The first stop 2221 and the second stop 2222 adopt a double stop design, and when they are connected, the fan cover 222 and the fan bottom shell 221 can be accurately positioned and tightly connected.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the base assembly 1 includes a base housing 11, which is connected to a rotating suction cup 12 for adsorbing onto an object. A first air inlet 31 and a second air inlet 32 ​​for fluid to flow into the first air inlet channel 301 and the second air inlet channel 302 are respectively provided between the base housing 11 and the rotating suction cup 12. The design of the rotating suction cup 12 allows the base assembly 1 to be firmly adsorbed onto a smooth or slightly uneven object surface. The first air inlet 31 and the second air inlet 32 ​​are located between the base housing 11 and the rotating suction cup 12, providing space for fluid to flow into the first air inlet channel 301 and the second air inlet channel 302, which helps with ventilation and heat dissipation of internal electronic components or other sensitive parts.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the base housing 11 is provided with a base fan housing 111 that mates with the fan base 221 to form an air inlet channel 3. The fan base 221 is provided with a third stop 2211 and a fourth stop 2212 that mates with the third stop 2211. The third stop 2211 is a second concave stop, and the fourth stop 2212 is a second convex stop. The second concave stop and the second convex stop are matched and connected to seal the connection gap between the base fan housing 111 and the fan base 221. The tight fit between the third stop 2211 and the fourth stop 2212 prevents fluid leakage and ensures the airtightness of the air inlet channel. Through the tight fit between the third stop 2211 and the fourth stop 2212, leakage of air or other fluids in the first air inlet channel 301 and the second air inlet channel 302 can be effectively prevented, ensuring the airtightness of the entire air inlet channel and helping to maintain the correct airflow path and pressure balance.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fan base 221 is provided with a fan inlet 320 that allows fluid from the first air inlet channel 301 and the second air inlet channel 302 to enter the fan device 2. This fan inlet design helps reduce noise caused by airflow turbulence. A smooth and direct airflow path typically generates less turbulent noise, providing a quieter operating environment.

[0041] The working principle of this embodiment is as follows:

[0042] The process of using a high-powered window cleaning machine, such as Figure 1 As shown, air or other fluid first flows in through the first and second air inlets located between the base shell and the rotating suction cup. The air or other fluid then flows into the fan inlet through the first and second air inlet channels, and then through the first and second air outlet channels. At this time, the air or other fluid can flow out through these two channels with less fluid resistance, which speeds up the outflow of the fluid. Due to the reduction of fluid resistance, the fluid in the first and second air inlet channels can flow quickly, which accelerates the extraction of air between the object and the base assembly. A negative pressure is formed between the object and the base assembly, which strengthens the adsorption force of the base assembly. The first air inlet, the second air inlet, the first air outlet, and the second air outlet are arranged in the same direction, which is beneficial for drying the moisture on the glass.

[0043] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
