Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, specifically a floor scrubber with a water vapor backflow prevention function. Background Technology

[0002] A floor scrubber is a cleaning device that integrates cleaning, water absorption, and drying. It is mainly used to efficiently remove stains, oil stains, or water stains from hard floors (such as ceramic tiles, marble, epoxy flooring, etc.). It uses a vacuum motor to suck the wastewater and foam back into the wastewater tank, keeping the floor dry.

[0003] The prior art (Chinese patent publication number: CN116491862A, publication date: 2023-07-28) discloses a wastewater tank for a floor scrubber and the floor scrubber itself. The wastewater tank contains a wastewater chamber for containing wastewater. Multiple water spray devices connected to an external water source are installed in the wastewater chamber, with at least one spray device located at the top of the wastewater chamber. A drain outlet connected to the suction pipe of the floor scrubber is located at the bottom of the wastewater chamber. A movable pipe section is installed within the wastewater chamber, having a first wastewater outlet near the drain outlet and a second wastewater outlet near the top of the wastewater chamber. The movable pipe section has an upward position within the wastewater chamber that moves the first wastewater outlet away from the drain outlet, and a downward position that connects the first wastewater outlet to the drain outlet. This invention overcomes the shortcomings of the prior art, such as the difficulty and low efficiency of cleaning the wastewater tank of the floor scrubber, thereby improving the cleaning effect and efficiency of the wastewater tank.

[0004] While existing floor scrubbers improve the cleaning effect and efficiency of the wastewater tank during use, they cannot prevent backflow of water when vacuuming the tank. Water may flow back into the vacuum motor through the connection point, damaging the motor.

[0005] Therefore, we proposed a cleaning machine with anti-backflow function to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide a cleaning machine with a water vapor anti-backflow function to solve the problem mentioned in the background art that the floor scrubber cannot prevent water backflow when vacuuming the inside of the water tank, and the water may backflow into the inside of the vacuum motor through the connection of the vacuum motor, thereby damaging the motor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleaning machine with anti-backflow function of water vapor, including an outer shell, a water storage cavity is provided inside the outer shell, and an anti-backflow structure is provided inside the water storage cavity. The anti-backflow structure includes a guide plate and an inclined plate fixed inside the water storage cavity. Through the cooperation of the guide plate and the inclined plate, the water vapor inside the floor scrubber can be prevented from backflowing.

[0008] Furthermore, a water injection groove is provided on the inner side of the outer shell, and the water injection groove and the water storage cavity are interconnected, and the water storage cavity is connected to the outside through the water injection groove.

[0009] Furthermore, the water inlet of the water injection tank is located above the guide plate, and the guide plate is configured with an arc-shaped bent structure, with the arc-shaped concave side of the guide plate facing the side of the water injection tank.

[0010] Furthermore, the inclined plate is fixedly installed inside the water storage cavity in an inclined structure, and a water injection channel is provided on the inclined plate, which is located below the lower end of the guide plate.

[0011] Furthermore, an upper partition and a lower partition are fixedly connected to the lower part of the water storage cavity, with the lower partition located below the upper partition.

[0012] Furthermore, the upper and lower partitions are provided with partition grooves at equal intervals, with four sets of partition grooves on the upper partition and five sets of partition grooves on the lower partition.

[0013] Furthermore, the length of the dividing groove on the upper partition is greater than the maximum length of the dividing groove on the lower partition, and the length of the upper partition is greater than the maximum length of the lower partition.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Water is injected into the water storage chamber through the water injection tank. At this time, the water flows out into the water storage chamber through the drain outlet of the water injection tank. The guide plate with the arc-shaped bending structure can guide and limit the flow of the discharged water, so that the water can flow into the water storage chamber through the water injection channel opened on the inclined plate. The guiding effect of the guide plate can limit the flow of water, thereby reducing the phenomenon of water flowing towards the fan docking part after entering the water storage chamber, and further reducing the backflow of water.

[0016] 2. The inclined plate is set at an angle inside the outer shell. The inclined plate can divide the water storage cavity inside the outer shell into upper and lower sides. At the same time, the inclined plate is provided with a water inlet channel for water to enter. This allows the inclined plate to ensure that water is injected normally into the water storage cavity, while also isolating and blocking the water. This further prevents the water level from changing when the user holds the outer shell and tilts it, thus preventing water from flowing back into the shell.

[0017] 3. The outer shell is equipped with upper and lower partitions of different lengths. Water can flow through the partition on the upper partition, which is set in the longer position, so that after the upper and lower partitions separate the water, the water in the water storage chamber is on the same plane, which further allows the water in the water storage chamber to be better cleaned later.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: As Figure 1 , Figure 2 and Figure 3The technical solution shown herein provides the following solution: A cleaning machine with anti-backflow function for water vapor, disclosing an anti-backflow structure. This structure reduces the backflow of water to the fan connection point. The outer casing 1 has a water storage chamber 8 inside, and the water storage chamber 8 is equipped with an anti-backflow structure. The anti-backflow structure includes a guide plate 3 and an inclined plate 4 fixed inside the water storage chamber 8. Through the cooperation of the guide plate 3 and the inclined plate 4, the backflow of water vapor inside the floor scrubber can be prevented. A water inlet 2 is provided on the inner side of the outer shell 1, and the water inlet 2 is connected to the water storage cavity 8. The water storage cavity 8 is connected to the outside through the water inlet 2. The water inlet of the water inlet 2 is located above the guide plate 3. The guide plate 3 is set in an arc-shaped bent structure, and the arc-shaped concave side of the guide plate 3 is set towards the water inlet 2. The inclined plate 4 is fixedly set inside the water storage cavity 8 in an inclined structure, and a water inlet channel 5 is provided on the inclined plate 4. The water inlet channel 5 is located below the lower end of the guide plate 3.

[0024] The outer casing 1 injects water into the water storage chamber 8 through the water injection tank 2. The water then flows out of the water storage chamber 8 through the drain outlet of the water injection tank 2. The arc-shaped, bent guide plate 3 guides and limits the flow of the discharged water, ensuring that it flows precisely into the water storage chamber 8 through the water injection channel 5 on the inclined plate 4. The guide plate 3 limits the direction of water flow, reducing the likelihood of water flowing towards the fan connection point after entering the water storage chamber 8. To reduce water backflow, the inclined plate 4 is installed at an angle inside the outer shell 1. The inclined plate 4 can divide the water storage cavity 8 inside the outer shell 1 into upper and lower sides. At the same time, the inclined plate 4 is provided with a water inlet channel 5 for water to enter. This allows the inclined plate 4 to ensure that water is injected normally into the water storage cavity 8, while also isolating and blocking the water. This further prevents the water level from changing when the user holds the outer shell 1 and the outer shell 1 is tilted, thus preventing water backflow.

[0025] Example 2: Figure 1 and Figure 3 The present invention provides the following technical solution: a cleaning machine with anti-backflow function for water vapor, comprising an upper partition 6 and a lower partition 7. By setting partition grooves 9 of different lengths on the upper partition 6 and the lower partition 7, the separated water bodies can still be at the same level. The upper partition 6 and the lower partition 7 are also fixedly connected to the lower part of the water storage cavity 8, and the lower partition 7 is located below the upper partition 6. Partition grooves 9 are equally spaced on the upper partition 6 and the lower partition 7. There are four sets of partition grooves 9 on the upper partition 6 and five sets of partition grooves 9 on the lower partition 7. The length of the partition grooves 9 on the upper partition 6 is greater than the maximum length of the partition grooves 9 on the lower partition 7, and the length of the upper partition 6 is greater than the maximum length of the lower partition 7.

[0026] The outer shell 1 is provided with an upper partition 6 and a lower partition 7 with different lengths of partition groove 9. At this time, the water can flow to the side of the upper partition 6 through the partition groove 9 set in the longer state on the upper partition 6. Thus, after the upper partition 6 and the lower partition 7 separate the water, the water in the water storage chamber 8 is on the same plane, which further allows the water in the water storage chamber 8 to be better cleaned in subsequent operations.

[0027] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
