Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an integrated capacitive filter. Background Art

[0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out a specific frequency point in the power line or frequencies other than the frequency point to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency.

[0003] Filters are generally used to suppress interference in circuits. Generally speaking, the normal operating temperature range of filters is between -25℃ and +85℃. If the filter cannot dissipate heat for a long time during use, its internal temperature may exceed the normal temperature range. Once this temperature range is exceeded, the filter may experience problems such as performance degradation or damage. Some existing filters cannot dissipate heat by themselves, and most of them are installed in ventilated places to dissipate heat. For this reason, we propose an integrated capacitive filter to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, through the cooperation between the fan and the dustproof net and other components, firstly, when the fan is started, the air in the device body can flow quickly, so that the air with a lower temperature outside the device body can enter the inside of the device body through the vents, thereby taking away the temperature of the parts in the device body to cool the device body. The dustproof net can block the dust in the air, thereby preventing the dust from adhering to the electronic parts in the device body as the air flows, thereby avoiding the situation where static electricity is easily generated due to too much dust. It is very easy to use and solves the problem that the filter cannot dissipate heat by itself.

[0015] 2. In the utility model, through the cooperation between the inclined plate and the limiting mechanism and other components, when there is dust on the dustproof net, the dust will naturally fall under the action of gravity, and the falling dust will fall on the inclined plate, which will transport the dust to a position away from the device body to avoid the dust from accumulating directly under the device body. The limiting mechanism can fix the position of the limiting shell, so that the limiting shell cannot be easily detached from the device body, thereby ensuring the stability of the equipment and being very convenient.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, an integrated capacitive filter includes a device body 1, the outer surface of the device body 1 is slidably connected to a limiting shell 2, a vent 3 is opened inside the limiting shell 2, the limiting shell 2 will cover one side of the device body 1, and air can flow into the limiting shell 2 through the vent 3.

[0024] A fan 4 is installed inside the limiting shell 2, and a dustproof net 5 is slidably connected inside the limiting shell 2. The outer surface of the dustproof net 5 is slidably connected to the outer surface of the device body 1. The fan 4 is connected to a motor. When the motor is started, the fan 4 can be rotated. The wind generated by the rotation of the fan 4 will blow into the device body 1, and the dustproof net 5 is clamped by the limiting shell 2 and the device body 1, so that the dustproof net 5 cannot move.

[0025] The bottom surface of the limiting shell 2 is fixedly connected with a support block 6, and the interior of the support block 6 is fixedly connected with an inclined plate 7. The upper surface of the inclined plate 7 is fixedly connected to the bottom surface of the limiting shell 2. The limiting shell 2 will fix the position of the support block 6. The position of the inclined plate 7 is fixed by the support block 6 and the limiting shell 2. The dust falling from the dustproof net 5 will fall on the inclined plate 7, and the inclined plate 7 will send the dust to a farther position.

[0026] The outer surface of the limit shell 2 is fixedly connected with a blocking plate 8, and the inner sliding connection of the blocking plate 8 is connected with a limiting rod 9. The bottom surface of the limiting rod 9 is fixedly connected to the upper surface of the device body 1. The position of the limit shell 2 is fixed by the blocking plate 8. The limiting rod 9 can prevent the blocking plate 8 from shaking, and the device body 1 will fix the position of the limiting rod 9.

[0027] A slide groove 10 is provided inside the limit rod 9, and a limiting mechanism 11 is arranged inside the limit rod 9. The limiting mechanism 11 includes a block 1101, which is slidably connected to the inner wall of the slide groove 10, and the block 1101 is slidably connected to the upper surface of the blocking plate 8. The inner wall of the slide groove 10 is relatively smooth, and other objects are subject to less friction when moving on the inner wall of the slide groove 10. The slide groove 10 will limit the moving direction of the block 1101, and the position of the blocking plate 8 is limited by blocking the block 1101 above the blocking plate 8. The block 1101 has an inclined surface, and when the blocking plate 8 presses the block 1101 from above, the block 1101 can be directly pushed back into the slide groove 10.

[0028] The outer surface of the block 1101 is fixedly connected with a spring 1102, and the end of the spring 1102 away from the baffle is fixedly connected to the inner wall of the slide groove 10. The inner wall of the slide groove 10 fixes the position of the spring 1102. The spring 1102 provides thrust to the block 1101, so that the block 1101 can be blocked on the blocking plate 8 when not subject to external force.

[0029] The outer surface of the stopper 1101 is fixedly connected to the transmission rod 1103, and the outer surface of the transmission rod 1103 is slidably connected to the inner wall of the slide groove 10. The spring 1102 is sleeved on the outer surface of the transmission rod 1103. When the transmission rod 1103 moves, the stopper 1101 will move with it, and the slide groove 10 will limit the position to which the transmission rod 1103 can move.

[0030] The end of the transmission rod 1103 away from the stop block 1101 is fixedly connected to the transmission block 1104, the outer surface of the transmission block 1104 is slidably connected to the inner wall of the slide groove 10, the upper surface of the limit rod 9 is slidably connected to the cross plate 12, the upper surface of the transmission block 1104 is fixedly connected to the bottom surface of the cross plate 12, when the transmission block 1104 moves, it will move with the transmission rod 1103, the slide groove 10 will limit the position to which the transmission block 1104 can move, and the movement of the cross plate 12 will drive the transmission block 1104 to move.

[0031] The transmission block 1104 is internally slidably connected with a slide rod 1105, and both ends of the slide rod 1105 are fixedly connected to the inner wall of the slide groove 10. The slide rod 1105 can prevent the transmission block 1104 from tilting when moving, and the slide groove 10 will fix the position of the slide rod 1105.

[0032] It should be noted that in actual use of the device, it is necessary to first place the dustproof net 5 into the limiting shell 2 and then cover the limiting shell 2 over the device body 1, and allow the limiting rod 9 to pass through the blocking plate 8. At this time, the spring 1102 will push the block 1101 out to block the blocking plate 8. When cooling is required, the fan 4 can be started. By starting the fan 4, the air in the device body 1 can flow, allowing cool air to enter the device body 1 to cool the device body 1. During the process of air entering, the dust inside the air will be blocked by the dustproof net 5, and finally fall on the inclined plate 7, and finally slide off the inclined plate 7.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
