[0036] Embodiment 1

[0037] A mounting structure of a filter device for an electric appliance, as shown in Figures 1 to 6 The electric appliance shell 3 is provided with an air inlet 3.1, the guide part 4 is fixed on the electric appliance shell 3 and slides along the wall surface where the air inlet 3.1 is located, and the filter device 1 is slidably installed along the guide part 4 until the air inlet 3.1 is blocked. The electric appliance shell 3 is provided with a hollow part 3.2 on the wall surface where the air inlet 3.1 is located, the hollow part 3.2 is installed with a guide device 2, the filter device 1 has elastic deformation capacity, and the hollow part 3.2 and the guide device 2 form a hollow slot 2.2 for the elastic deformation of the filter device 1 to guide the filter device 1 from the hollow part 3.2 to the matching guide part 4.

[0038] In the scheme disclosed in the present application, the electric appliance shell 3 and the filter device 1 are connected by sliding through the guide part 4, the filter device 1 is convenient to disassemble and assemble, and the efficiency of maintenance and replacement is high.

[0039] The guide part 4 includes but is not limited to a guide rail, a guide groove 4.1 and a guide frame, etc., the edge of the filter device 1 is slidably matched with the guide part 4, for example, when the guide part 4 is the guide groove 4.1 or the guide frame, the edge of the filter device 1 slides in the guide groove 4.1 or the guide frame, and when the guide part 4 is the guide rail, the edge of the filter device 1 can be provided with a sliding groove to match the sliding connection of the guide rail.

[0040] When the filter device 1 is installed, it slides along the guide part 4, the guide part 4 limits the filter device 1, and the filter device 1 does not touch the area behind the guide part 4, so as to avoid the disassembly and assembly of the filter screen from interfering with the electrical elements inside the electric appliance shell 3, and ensure the service life of the electric appliance.

[0041] The hollow part 3.2 and the air inlet 3.1 of the filter device 1 are arranged on the same side of the electric appliance shell 3, and the integrity of the other side of the electric appliance shell 3 can be ensured.

[0042] The filter device 1 includes but is not limited to a filter screen, a filter frame with a filter screen, and various filters.

[0043] Embodiment 2

[0044] As shown in Figures 1 to 6 An installation structure of a filter device for an electric appliance includes an electric appliance shell 3, a guide part 4, and a filter device 1. The electric appliance shell 3 is provided with an air inlet 3.1. The guide part 4 is fixed to the electric appliance shell 3 and slides along the wall surface where the air inlet 3.1 is located.

The filter device 1 is slidingly installed along the guide part 4 until it blocks the air inlet 3.1. The air inlet 3.1 includes a plurality of parallel or collinear strip-shaped through holes. The strip-shaped through holes serve as air inlet units of the air inlet 3.1. The structure of the air inlet 3.1 formed by the plurality of strip-shaped through holes can play a role in preliminary filtration, and can block larger solid particles outside the electric appliance shell 3 to avoid direct entry into the electric appliance shell 3 and damage the filter device 1. Figure 1The middle arrow points to the air inlet direction. The electric appliance shell 3 is provided with a hollow part 3.2 for the filter device 1 to enter and exit on the wall surface where the air inlet 3.1 is located.

In this embodiment, the hollow part 3.2 is a through hole penetrating the wall surface of the electric appliance shell 3. The filter device 1 adopts a filter screen plate capable of elastic deformation. The hollow part 3.2 and the guide device 2 form a hollow slot 2.2 for the filter device 1 to elastically deform through, so as to guide the filter device 1 from the hollow part 3.2 to the matching guide part 4. In order to ensure the guiding effect of the guide device 2, further, the guide device 2 is directly installed in the hollow part 3.2, so that the filter device 1 is inserted into the guide device 2 when being inserted into the hollow part 3.2. At this time, the upper side of the hollow part 3.2 is the upper side of the guide device 2 connecting one end of the hollow part 3.2.

[0045] In this embodiment, the filter device 1 is provided with a handle 1.1. The handle 1.1 is located in the hollow part 3.2 or extends outside the hollow part 3.2 when the filter device 1 is slidably installed in place along the guide part 4. For example, Figure 2 The middle handle 1.1 extends outside the hollow part 3.2 when the filter device 1 is slidably installed in place along the guide part 4, and according to Figure 5 It can be seen that the handle 1.1 is arranged on the side of the hollow part 3.2 away from the guide part 4. In this embodiment, the hollow part 3.2 is located on the upper side of the air inlet 3.1. That is, the handle 1.1 is attached to the upper side of the hollow part 3.2.

[0046] When the filter device 1 is disassembled from the electric appliance shell 3, the handle 1.1 can be manually operated. The handle 1.1 is pressed downward while being pulled outwards, so that the upper end of the filter device 1 deforms after matching the guide part 4 and can be pulled out of the hollow part 3.2, thereby ensuring the disassembly efficiency of the filter device 1.

[0047] Embodiment 3

[0048] For example, Figures 1 to 6As shown, the mounting structure of the filter device for the electrical appliance comprises an electrical appliance shell 3, a guide part 4 and a filter device 1. The electrical appliance shell 3 is provided with an air inlet 3.1. The guide part 4 is fixed on the electrical appliance shell 3 and slides along the wall surface where the air inlet 3.1 is located. The guide part 4 is provided with two guide grooves 4.1 oppositely arranged on both sides of the air inlet 3.1 to respectively match a group of opposite edges of the filter device 1. The cross section of the guide part 4 is L-shaped. One end of the guide part 4 is vertically welded on the electrical appliance shell 3 to form the guide groove 4.1. The filter device 1 is slidably mounted along the guide part 4 until the air inlet 3.1 is blocked. The air inlet 3.1 comprises a plurality of strip-shaped through holes arranged in parallel or in line. The strip-shaped through holes serve as the air inlet unit of the air inlet 3.1. The structure of the air inlet 3.1 formed by the strip-shaped through holes can play a role in preliminary filtering, which can block the solid with a larger volume outside the electrical appliance shell 3 to avoid direct entry into the electrical appliance shell 3 and damage the filter device 1. The electrical appliance shell 3 is provided with a hollow part 3.2 on the wall surface where the air inlet 3.1 is located for the filter device 1 to enter and exit. The hollow part 3.2 is a through hole penetrating the wall surface of the electrical appliance shell 3. The hollow part 3.2 is provided with a guide device 2. The filter device 1 has an elastic deformation capability. In this embodiment, the filter device 1 adopts a filter screen plate capable of elastic deformation. The hollow part 3.2 and the guide device 2 form a hollow groove 2.2 for the filter device 1 to elastically deform through, so as to guide the filter device 1 from the hollow part 3.2 to the matching guide part 4.

[0049] The guide device 2 comprises a connecting part 2.1 connected with the electrical appliance shell 3 and a guide arc surface 2.3 fixed to the connecting part 2.1. The two ends of the guide arc surface 2.3 are respectively abutted to the hollow part 3.2 and the guide part 4. The connecting part 2.1 is connected with the electrical appliance shell 3. The guide arc surface 2.3 is used for guiding when the filter device 1 is inserted. When the filter device 1 is inserted, the end of the filter device 1 hits the guide arc surface 2.3 to turn, and then matches the guide part 4 to ensure the reliable insertion of the filter device 1. In this embodiment, the connecting part 2.1 is a ring-shaped structure surrounding the hole wall of the hollow part 3.2 and is clamped on the wall surface of the electrical appliance shell 3, such as Figure 5 and Figure 6It can be seen that the connecting part 2.1 is engaged with the hollow part 3.2 from the outside to the inside, and the guide arc surface 2.3 extends from the hollow part 3.2 into the interior of the electrical housing 3. Further, the guide arc surface 2.3 includes a first end face 2.31, a middle arc surface 2.32, and a second end face 2.33. The first end face 2.31 and the second end face 2.33 are located at opposite ends of the middle arc surface 2.32. The second end face 2.33 engages with the guide part 4 and is parallel to the sliding direction of the guide part 4. The first end face 2.31 corresponds to the side of the hollow part 3.2 away from the guide part 4. In this embodiment, the hollow part 3.2 is located above the air inlet 3.1, and the guide part 4 is located on both sides of the air inlet 3.1. Therefore, the first end face 2.31 fits against the upper side of the hollow part 3.2, ensuring that the filter device 1 can be inserted into the hollow part 3.2. Furthermore, the distance between the second end face 2.33 and the side of the electrical housing where the air inlet 3.1 is located is less than the width of the guide groove 4.1, so that under the guiding action of the second end face 2.33, the lower end of the filter device 1 is guided along the second end face 2.33 and then located in the guide groove 4.1, ensuring reliable cooperation between the filter device 1 and the guide groove 4.1.

[0050] Example 4

[0051] like Figures 1 to 6 As shown, an installation structure for an electrical appliance filter includes an appliance housing 3, a guide portion 4, and a filter device 1. The appliance housing 3 has an air inlet 3.1. The guide portion 4 is fixed to the appliance housing 3 and slides along the wall surface where the air inlet 3.1 is located. The guide portion 4 consists of two guide grooves 4.1 arranged opposite to each other on both sides of the air inlet 3.1 to respectively cooperate with a set of opposite edges of the filter device 1. The cross-section of the guide portion 4 is L-shaped, and one end of the guide portion 4 is vertically welded to the appliance housing 3 to form the guide groove 4.1. The filter device 1 is slidably installed along the guide portion 4 until it blocks the air inlet 3.1. The air inlet 3.1 includes several parallel or collinear strip-shaped through holes. The strip-shaped through holes serve as the air intake units of the air inlet 3.1. The structure of the air inlet 3.1 formed by the several strip-shaped through holes can play a preliminary filtering role, blocking larger solids outside the appliance housing 3 and preventing them from directly entering the appliance housing 3 and damaging the filter device 1. The electrical housing 3 has a perforated portion 3.2 on the wall surface where the air inlet 3.1 is located, allowing the filter device 1 to enter and exit. A guide device 2 is installed in the perforated portion 3.2. The filter device 1 has elastic deformation capability. In this embodiment, the filter device 1 adopts a filter screen that can elastically deform. The perforated portion 3.2 and the guide device 2 form a perforated groove 2.2 through which the filter device 1 elastically deforms to guide the filter device 1 from the perforated portion 3.2 to the mating guide portion 4.

[0052] The first curved portion 1.3 is provided at one end of the filter device 1 inserted into the hollow portion 3.2, and the curved direction of the first curved portion 1.3 is consistent with the curved direction of the guide curved surface 2.3. The second curved portion 1.4 is provided at the opposite end of the filter device 1 from the first curved portion 1.3, and the first curved portion 1.3 and the second curved portion 1.4 are both cylindrical curved surface structures. The curved direction of the second curved portion 1.4 is consistent with the curved direction of the guide curved surface 2.3, where "consistent curved direction" means that the curved surface extension directions are consistent, such as Figure 4 From the top to the bottom, the guide curved surface 2.3 is curved and extends in a clockwise direction, and the first curved portion 1.3 and the second curved portion 1.4 are also curved and extend in a clockwise direction. The first curved portion 1.3 and the second curved portion 1.4 are respectively located at the lower end and the upper end of the filter screen plate, and play a role in strengthening the upper end and the lower end of the filter screen plate. The two sides of the filter screen plate are also limited by the guide groove 4.1, so that the four edges of the filter screen plate are not easy to deform, and can reliably withstand the wind pressure of the air inlet 3.1, so that the filter screen plate can still ensure the reliable filtering effect although it can elastically deform.

[0053] The second curved portion 1.4 is provided with a mounting portion 1.2 that covers the end surface of the hollow portion 3.2. As known from the previous embodiment, the connecting portion 2.1 is clamped around the hole wall of the hollow portion 3.2, as shown in Figure 5 and Figure 6 The outer end of the connecting portion 2.1 is provided with an annular clamping groove to cooperate with the limiting mounting portion 1.2, and the handle 1.1 is vertically arranged on the outside of the mounting portion 1.2.

The filter screen plate is arranged in a spaced manner with the inner wall surface of the electric appliance shell 3. As shown in Figure 4 When the filter screen plate is installed in place, the filter screen plate is arranged on the side away from the air inlet 3.1 and close to the guide portion 4. When the filter screen plate to be replaced is pulled out upward, the side of the filter screen plate facing the air inlet 3.1 accumulates a lot of dust. The filter screen plate is elastically deformed and pulled out of the hollow portion 3.2, so that it is tightly attached to the guide portion 4 under the action of the elastic force, and the situation that the dust on the surface of the filter screen plate is scraped into the electric appliance shell 3 from the lower side of the hollow portion 3.2 does not occur, and the first curved portion 1.3 also has the effect of preventing dust from falling into the electric appliance shell 3 from the lower side of the filter screen plate.
