Description

Technical Field

[0001] The utility model relates to the field of dust filtering, in particular to a filtering component and a camera device. Background Art

[0002] In dusty industrial sites such as coal mines, the camera lens often suffers from reduced shooting quality due to dust accumulation. To ensure shooting quality, the camera can only be cleaned more frequently. Usually, the camera is cleaned by a fan and an air filter. The air filter first filters the dust in the air, and then the fan uses the filtered air to blow and clean the camera lens.

[0003] Due to the high frequency of cleaning, the filter element in the air filter device is often clogged, and each replacement of the filter element involves the overall disassembly and assembly of the air filter device, resulting in a large workload for camera cleaning. Utility Model Content

[0004] Based on this, it is necessary to provide a filter component and a camera device to address the problem of heavy workload in camera cleaning.

[0005] A filter assembly includes a filter housing and a filter element. A filter channel is arranged in the filter housing. The filter channel has at least two filter stations. The filter channel also has a first side wall and a second side wall arranged opposite to each other. At least one filter element is arranged at each filter station. The filter element is movably arranged between the first side wall and the second side wall.

[0006] The filtering stations of the utility model are arranged in sequence and at intervals in the extending direction of the filtering channel.

[0007] The first side wall of the utility model is provided with a first sealing block, and the first sealing block is located between two adjacent filter elements and is fitted with the filter elements.

[0008] The filter assembly of the utility model also includes a control plate, which includes a plate body and at least two first wedge blocks, the first wedge blocks are fixed on the surface of the plate body, the plate body is slidably arranged on the first side wall, and the edge of the filter element is provided with a second wedge block, and the first wedge block is used to push the corresponding second wedge block toward the second side wall.

[0009] The filter assembly of the utility model further comprises an elastic member, wherein the elastic member is located between the first side wall and the second side wall, and the elastic member is used to push the filter element toward the first side wall.

[0010] In the utility model, a guide rod is arranged on the second side wall, a guide tube is arranged on the side edge of the filter element, and the guide rod is arranged through the middle of the guide tube.

[0011] In the utility model, a baffle is arranged at one end of the first side wall, and the baffle is attached to the filter element.

[0012] The filter housing of the utility model is provided with an air inlet and an air outlet, and the filter channel is located between the air inlet and the air outlet.

[0013] The second side wall of the utility model is provided with a second sealing block, and the second sealing block is located between two adjacent filtering stations to allow the second sealing block to fit the filter element.

[0014] A camera device comprises a camera, a fan and a filter assembly, wherein the fan is mounted on the camera and connected to the filter channel.

[0015] The beneficial effects of the utility model are:

[0016] The filter element has an avoidance state and a filtering state, and the filter element switches between the two states by moving between the first side wall and the second side wall. When the blocked filter element is switched to the avoidance state, there is a large gap between the blocked filter element and the second side wall, and the air can pass through the gap to pass through the blocked filter element, ensuring the normal flow of air. When the unblocked filter element is switched to the filtering state, there is only a small gap or no gap between the unblocked filter element and the second side wall, and most of the air needs to be filtered by the filter element before it can pass through the filter element, ensuring that the filter assembly can normally filter dust in the air.

[0017] Only when all filter elements are clogged do they need to be replaced uniformly. Therefore, the time interval for filter element replacement is significantly increased, and correspondingly, the actual workload generated by filter element replacement is significantly reduced.

[0037] Example:

[0038] See also Figure 1-Figure 4 This embodiment provides a camera device, including a camera 5, a fan 6 and a filter assembly, wherein the filter assembly includes a filter housing 1 and a filter element 2. The first direction, the second direction and the third direction are perpendicular to each other.

[0039] A filter channel 11 is provided in the filter housing 1, and the filter element 2 is installed in the filter channel 11. An air inlet 12 and an air outlet 13 are also provided on the filter housing 1. The filter channel 11 is located between the air inlet 12 and the air outlet 13. The air outlet 13 is connected to the fan 6, and the fan 6 is installed on the camera 5. The fan 6 provides suction, so that the air with dust enters the filter channel 11 through the air inlet 12, and the dust is filtered by the filter element 2. The filtered air enters the fan 6 through the air outlet 13, and then the lens of the camera 5 is purged.

[0040] Different from the prior art, the filter channel 11 of this embodiment has at least two filter stations, and each filter station is provided with at least one filter element 2. Figure 5-Figure 7 There are three filter stations in the filter channel 11, which are arranged in sequence in the second direction, and each filter station is provided with a filter element 2. For the convenience of distinction, the three filter elements 2 are respectively referred to as the first filter element 23, the second filter element 24 and the third filter element 25.

[0041] The filter channel 11 has a first side wall 111 and a second side wall 112 arranged opposite to each other in a first direction, and the filter element 2 is slidably arranged between the first side wall 111 and the second side wall 112 along the first direction, so that the filter element 2 has an avoidance state and a filtering state. When the filter element 2 is in the avoidance state, the distance between the filter element 2 and the second side wall 112 is d 1 When the filter element 2 is in the filtering state, the distance between the filter element 2 and the second side wall 112 is d 2 , d 1 >d 2 , where d 2 ≥0.

[0042] See also Figure 5, at this time, the first filter element 23 is in the filtering state, while the second filter element 24 and the third filter element 25 are in the avoidance state. Dust-laden air flows into the air inlet 12. Since there is a small gap or no gap between the first filter element 23 and the second side wall 112, and there is a large gap between the second filter element 24 and the third filter element 25 and the second side wall 112, most of the air can only enter the filter channel 11 through the first filter element 23, and then go directly to the air outlet 13. The second filter element 24 and the third filter element 25 have only a small amount of or no filtering effect. This working state is suitable for the situation where the first filter element 23 is not blocked, but the second filter element 24 and the third filter element 25 are blocked.

[0043] See also Figure 6 , at this time, the second filter element 24 is in the filtering state, while the first filter element 23 and the third filter element 25 are in the avoidance state. The air with dust flowing into the air inlet 12 can enter the filter channel 11 through the gap between the first filter element 23 and the second side wall 112, and then be filtered by the second filter element 24, and then pass through the third filter element 25 to directly reach the air outlet 13. This working state is suitable for the situation that the second filter element 24 is not blocked, but the first filter element 23 and the third filter element 25 are blocked.

[0044] See also Figure 7 At this time, the third filter element 25 is in the filtering state, and the first filter element 23 and the second filter element 24 are in the avoiding state. The dusty air flowing into the air inlet 12 can directly pass through the first filter element 23 and the second filter element 24, be filtered by the third filter element 25, and then reach the air outlet 13. This working state is suitable for the situation that the third filter element 25 is not blocked, but the first filter element 23 and the second filter element 24 are blocked.

[0045] The filter assembly of this embodiment can switch the blocked filter element 2 to the avoidance state to avoid it from hindering the flow of air, and at the same time switch the unblocked filter element 2 to the filtering state to ensure that the filter assembly can filter the dust in the air normally. Only when all the filter elements 2 are blocked, all the filter elements 2 need to be replaced uniformly, so the time interval for replacing the filter element 2 is also significantly increased, and accordingly, the actual workload generated by replacing the filter element 2 is also significantly reduced.

[0046] Preferably, the filtering stations are arranged in sequence and spaced apart in the extending direction of the filtering channel 11, and correspondingly, the adjacent filter elements 2 are also arranged in spaced apart. Figure 6 For example, after passing through the first filter element 23, the air can utilize the gap between the first filter element 23 and the second filter element 24 to fully contact the second filter element 24, thereby allowing the second filter element 24 to be fully utilized. Figure 7The gap between the second filter element 24 and the third filter element 25 also allows the third filter element 25 to be fully utilized during air filtering.

[0047] In this embodiment, two first sealing blocks 113 are arranged on the first side wall 111, one of which is located between the first filter element 23 and the second filter element 24, and the other is located between the second filter element 24 and the third filter element 25. Regardless of whether the filter element 2 is in the avoidance state or the filtering state, the first sealing block 113 always keeps in contact with the two adjacent filter elements 2. Figure 5 In this working state, the first sealing block 113 between the first filter element 23 and the second filter element 24 can block the gap between the first filter element 23 and the first side wall 111, preventing air from directly passing through the first filter element 23 to reach the gap between the first filter element 23 and the second filter element 24, ensuring that the first filter element 23 can filter the air. Figure 6 In this working state, the two first sealing blocks 113 can ensure that the second filter element 24 has a filtering effect on the air.

[0048] Similar to the first sealing block 113, a baffle 114 is disposed at one end of the first side wall 111, and the baffle 114 is attached to the third filter element 25. Figure 7 In this working state, the baffle 114 ensures that the third filter element 25 can play a filtering effect and prevents air from flowing directly to the air outlet 13.

[0049] In addition, the baffle 114 and the first sealing block 113 are spaced apart from the second side wall 112 to avoid blocking the air inlet 12 and the air outlet 13 .

[0050] Further preferably, two second sealing blocks 116 are provided on the second side wall 112, wherein one second sealing block 116 is located between the filtering stations where the first filter element 23 and the second filter element 24 are located, and the other second sealing block 116 is located between the filtering stations where the second filter element 24 and the third filter element 25 are located. Figure 5 In this working state, the second sealing block 116 and the first filter element 23 are in contact with each other, and the second sealing block 116 blocks the gap between the first filter element 23 and the second side wall 112. The air at the air inlet 12 can only pass through the first filter element 23 to reach the air outlet 13. Figure 6 In this working state, the second sealing block 116 and the second filter element 24 are in contact with each other, and the second sealing block 116 blocks the gap between the second filter element 24 and the second side wall 112. The air between the first filter element 23 and the second filter element 24 can only reach the air outlet 13 after being filtered by the second filter element 24. Figure 7In this working state, the second sealing block 116 and the third filter element 25 are in contact with each other, and the air between the second filter element 24 and the third filter element 25 can reach the air outlet 13 only after being filtered by the third filter element 25 .

[0051] See also Figure 8 The filter assembly of this embodiment further includes a control board 3, which includes a plate body 31 and at least two first wedge blocks 32, and the first wedge blocks 32 are fixed on the surface of the plate body 31. The number of the first wedge blocks 32 is consistent with the number of the filter elements 2, so that the first wedge blocks 32 and the filter elements 2 correspond one to one, and the first wedge blocks 32 can control the corresponding filter element 2 to move in the first direction. Accordingly, there are three first wedge blocks 32 in this embodiment, and the three first wedge blocks 32 are arranged in sequence in the second direction.

[0052] The plate 31 is slidably arranged on the first side wall 111 along the third direction. For example, in this embodiment, a linear drive 7 is installed on the filter housing 1. The linear drive 7 can be a linear motor. The linear drive 7 controls the plate 31 to move in the third direction. The edge of the filter element 2 is provided with a second wedge block 21. The first wedge block 32 can slide toward the corresponding second wedge block 21, so that the filter element 2 moves toward the second side wall 112. Fig. 9 At this time, the filter element 2 is in an evasive state, and the second wedge block 21 abuts against the plate body 31. Fig.11 At this time, the filter element 2 is in a filtering state, and the second wedge block 21 and the corresponding first wedge block 32 abut against each other.

[0053] See also Fig.10 , a guide rod 115 is provided on the second side wall 112, a guide tube 22 is provided on the side edge of the filter element 2, and the guide rod 115 is inserted in the middle of the guide tube 22 to guide the movement of the filter element 2 in the first direction. In addition, the filter assembly also includes an elastic member 4, which is sleeved on the guide rod 115 and located in the guide tube 22, and the two ends of the elastic member 4 are respectively abutted on the guide rod 115 and the guide tube 22. When the second wedge block 21 and the first wedge block 32 are separated, the elastic member 4 can push the filter element 2 toward the first side wall 111 again, so that the second wedge block 21 is abutted on the plate body 31 again.

[0054] In this embodiment, when one filter element 2 is in the filtering state, the other two filter elements 2 are in the avoidance state. The linear drive 7 can control the three filter elements 2 to switch from the avoidance state to the filtering state in sequence, and when all three filter elements 2 are blocked, they are replaced uniformly.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
