Embodiment 1

[0048] Example one, as figure 1 , 2 and Figure 4 shown:

[0049] The protective structure for preventing garbage from being sucked into the cleaning equipment due to missing filter elements includes a casing 1. The casing 1 is provided with a first cavity 21 for accommodating the impeller 3, and a second cavity 22 for accommodating the filter element 4. The first cavity 21 is connected with the discharge port 211, the second cavity 22 is connected with the sewage suction port 221, the first cavity 21 and the second cavity 22 are connected through the first channel 23, and there is also a connection between the second cavity 22 and the outside world. The number of the second channel 222 is more than one, and the filter element 4 is provided with a blocking member 41 for blocking the second channel 222.

[0050] The cleaning robot with the impeller 3 is the negative pressure generated in the first cavity 21 by the rotation of the impeller 3, so that the external fluid is pre...

Embodiment 2

[0053] Embodiment 2, Embodiment 2 is suitable for long tubular negative pressure cleaning equipment, such as a hand-held negative pressure cleaner, which is optimized on the basis of Embodiment 1, specifically as Figure 5 to Figure 15 shown:

[0054] The protective structure for preventing garbage from being sucked into the cleaning equipment due to missing filter elements includes a casing 1. The casing 1 is provided with a first cavity 21 for accommodating the impeller 3, and a second cavity 22 for accommodating the filter element 4. The first cavity 21 is connected with the discharge port 211, the second cavity 22 is connected with the sewage suction port 221, the first cavity 21 and the second cavity 22 are connected through the first channel 23, and there is also a connection between the second cavity 22 and the outside world. The number of the second channel 222 is more than one, and the filter element 4 is provided with a blocking member 41 for blocking the second chan...

Embodiment 3

[0058] Embodiment 3, Embodiment 3 is the optimization carried out on the basis of Embodiment 2, such as Figure 5 to Figure 21 shown:

[0059] On the basis of the second embodiment, the number of the discharge ports 211 and the second passages 222 is the same. Corresponding to the second passage 222 is arranged around the outer periphery of the first cavity 21 , the main casing 11 is provided with the discharge ports 211 and the second passages communicating with each other. The groove body 112 of the channel 222 , that is, the discharge port 211 and the second channel 222 are arranged adjacent to each other on the main casing 11 , and the main casing 11 is provided with the groove body 112 communicating with the discharge port 211 and the second passage 222 . Figure 16 to Figure 19 The structure of the tank body 112 is shown. For the convenience of expression, please refer to the positional relationship between the tank body 112, the discharge port 211, the second channel 22...

Abstract

The invention discloses a protection structure for preventing garbage from being sucked into cleaning equipment due to neglected loading of a filter element, the protection structure comprises a shell, a first cavity for accommodating an impeller and a second cavity for accommodating the filter element are arranged in the shell, the first cavity is communicated with a discharge port, the second cavity is communicated with a sewage suction port, and the first cavity and the second cavity are connected through a first channel; a second channel communicated with the second cavity and the outside is further formed, and the filter element is provided with a blocking piece used for blocking the second channel. When the filter element is forgotten to be installed for cleaning operation, external fluid can flow into the second cavity and the first cavity through the second channel until the fluid is discharged back to the outside from the discharge port, and the negative pressure generated by the impeller can be filled by the fluid flowing into the second channel, so that the negative pressure borne by the sewage suction port can be greatly weakened, and the cleaning effect is greatly improved. Therefore, garbage pollution to the interior of the equipment is reduced or avoided. According to the structure, a fault-tolerant mechanism is effectively created, the system is friendly to a user, the equipment is well protected, electronic monitoring equipment does not need to be additionally arranged, and the electronic detection cost is saved.

Description

technical field [0001] The invention belongs to the field of cleaning equipment, and in particular relates to a protection structure for preventing garbage from being sucked into cleaning equipment due to missing filter elements. Background technique [0002] Between two connected spaces, if the densities of the contents between each other are not equal, the high-density contents will flow to the low-density contents. Using this principle, vacuum cleaners and underwater cleaning robots are manufactured. It uses the work of the motor and the impeller to generate negative pressure. The impeller of the vacuum cleaner urges the outside air to rush to the impeller, and at the same time brings dust and garbage into the filter element in the equipment. The underwater cleaning robot uses the impeller to urge the outside water to rush to the impeller. At the same time, the garbage at the bottom is brought into the filter element in the equipment, and then the filtered water is discha...
