DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, the present invention provides an air sampling and filtering device with a cleaning function, comprising a processing chamber 1, a dust cover 2 is arranged on the top of the processing chamber 1, a collecting member 3 is installed on the top of the dust cover 2, a swing mechanism 4 is arranged inside the processing chamber 1, and a cleaning mechanism 5 is arranged at the bottom of the processing chamber 1;

[0029] The swing mechanism 4 includes a filter plate 41, a telescopic spring 42, a telescopic column 43, a swing rod 44 and an eccentric wheel 45. The telescopic spring 42 and the telescopic column 43 are respectively provided with two groups, and the two groups of telescopic springs 42 and telescopic columns 43 are symmetrically distributed at both ends of the filter plate 41. The swing rod 44 is rotatably connected to the top surface of the filter plate 41, and one end of the swing rod 44 is rotatably connected to the eccentric wheel 45.

[0030] The cleaning mechanism 5 includes a gathering plate 51, a push plate 52, an inclined block 53 and a return spring 54. The push plate 52 is fixedly connected to the top of the gathering plate 51, and the opposite sides of the two inclined blocks 53 are overlapped with the push plate 52. One end of the return spring 54 is fixedly connected to one end of the inclined block 53.

[0031] The above scheme is adopted: the sampling pump is used as a power device to provide suction for extracting external air, so that the external air to be sampled can smoothly enter the entire device through the input pipe, and then the air is transported from the output pipe to the processing chamber 1 through its pressurization and other effects. The input pipe builds a channel between the external environment and the sampling pump, which is used to guide the external air into the sampling pump. Its input end can be placed at the position where air needs to be collected according to actual needs. The output pipe connects the output end of the sampling pump with the processing chamber 1, and transports the air processed by the sampling pump to the processing chamber 1, ensuring that the air accurately enters the processing chamber 1 to start subsequent filtering and other processing processes. Through the setting of the swing mechanism 4, the driving motor 6 drives the eccentric wheel 45 to rotate. When the eccentric wheel 45 rotates, one end of the swing rod 44 passes through the internal fixed rotation The shaft is rotatably connected to the eccentric wheel 45, and the other end of the swing rod 44 is rotatably connected to the top surface of the filter plate 41, and two groups of telescopic springs 42 and telescopic columns 43 are symmetrically distributed at both ends of the filter plate 41. Driven by the rotation of the eccentric wheel 45, the swing rod 44 pushes the filter plate 41 to swing to a certain extent, and the telescopic spring 42 and the telescopic column 43 play the role of supporting the filter plate 41 and assisting its reset and buffering the swing. Through the swing of the filter plate 41, the impurities accumulated on the filter plate 41 can be distributed more evenly, avoiding local blockage of the filter holes, and ensuring that the filtering work is carried out continuously and stably, thereby ensuring that the filtering work can be carried out continuously and stably, without the need to frequently stop the machine to clean the blocked impurities on the filter plate 41, thereby improving the continuity and processing efficiency of the entire air treatment process.

[0032] like Figures 1 to 6 As shown, a driving motor 6 is installed on one side of the top of the dust cover 2, and the bottom surface of the processing chamber 1 is provided with four supporting legs in a rectangular array, and the top surfaces of the four supporting legs are fixedly connected to the bottom surface of the processing chamber 1, and grooves are provided on both sides of the inside of the processing chamber 1, and the grooves are provided for installing a push plate 52, an inclined block 53 and a reset spring 54, and fixed blocks 7 are fixedly connected on both sides of the processing chamber 1, and the collection component 3 includes a sampling pump, an input pipe and an output pipe, the output end of the input pipe is connected to the input end of the sampling pump, and the input end of the input pipe is used to extract external air to be sampled, the input end of the output pipe is connected to the output end of the sampling pump, and the output end of the output pipe is connected to the processing chamber 1, and the surface of the filter plate 41 is provided with filter holes for filtering impurities, and two groups of telescopic springs 42 are sleeved on the surfaces of two telescopic columns 43, one end of the two groups of telescopic springs 42 are respectively connected to the two sides of the filter plate 41, and the other end of the two groups of telescopic springs 42 are connected to the inner wall of the processing chamber 1.

[0033] The above scheme is adopted: through the setting of the cleaning mechanism 5, the filtered impurities will gradually gather on the filter plate 41, and some impurities will fall to the collecting plate 51 below under the action of gravity, etc. The size of the collecting plate 51 is adapted to the processing chamber 1, and a collecting groove is provided inside it for collecting impurities that fall from the filter plate 41 and are subsequently pushed over. The restriction of the card block on the ring is pulled out. At this time, the pressure of the return spring 54 is in contact, and the return spring 54 will drive the two inclined blocks 53 to move to both sides, and the inclined block 53 is separated from the push plate 52. The collecting plate 51 is pulled downward to clean the collected impurities, and the impurities can be processed in a centralized manner. This cleaning method is relatively simple and flexible to operate, does not require complicated tools or cumbersome steps, and is convenient for installing and disassembling the collecting plate 51. The sorting bin 1 is the main structure of the entire device, providing accommodation and installation space for the internal filtering swing mechanism 4, cleaning mechanism 5 and air treatment process, and the supporting legs at the bottom ensure that the entire device is placed stably. The grooves on both sides are used to install the push plate 52, inclined block 53 and reset spring 54 in the cleaning mechanism 5. The fixed blocks 7 on both sides may be used to connect with other external structures or to enhance the overall structural stability of the processing bin 1 (the specific role of the fixed block 7 is not clearly mentioned in the text, so it is speculated). The dust cover 2 is installed on the top of the processing bin 1 to prevent external dust and other impurities from entering the processing bin 1 at will, ensuring that the air entering the processing bin 1 is mainly input in a controlled manner through the collecting piece 3, protecting the various working components in the processing bin 1 and ensuring that the air treatment working environment is relatively clean.

[0034] like Figures 1 to 6 As shown, a rotating shaft is fixedly connected inside one end of the swing rod 44, and the rotating shaft is rotatably connected to the eccentric wheel 45 through the swing rod 44. A rotating block is fixedly connected to the top surface of the eccentric wheel 45, and the rotating block is splined to the output end of the driving motor 6. The size of the gathering plate 51 is adapted to the size of the processing bin 1. There are two groups of gathering plates 51, push plates 52, inclined blocks 53 and reset springs 54. The opposite sides of the two inclined blocks 53 are inclined, and the two sides of the push plates 52 are also inclined. A gathering groove for collecting impurities is provided inside the gathering plate 51, and the other end of the reset spring 54 is fixedly connected to a straight plate 541, which is connected to the inner wall of the processing bin 1, and one end of the straight plate 541 is fixedly connected to a collar, and a support rod 542 is provided inside the collar, and blocks are installed at both ends of the support rod 542.

[0035] The above scheme is adopted: the filter component at the core of the filter plate 41, the filter holes on the surface can filter impurities in the air entering the processing chamber 1, and intercept impurities such as particles in the air above it, ensuring that the air passing through it is relatively clean, and it can swing under the drive of the swing rod 44, the eccentric wheel 45 and other components, which is conducive to the uniform distribution of impurities and prevents the filter holes from being blocked. The telescopic spring 42 and the telescopic column 43 are symmetrically distributed at both ends of the filter plate 41, and the telescopic spring 42 is sleeved on the surface of the telescopic column 43. The telescopic spring 42 supports the weight of the filter plate 41 and buffers the filter plate 41 when it swings. The telescopic column 43 provides guidance and support for the telescopic spring 42 to ensure the stability of its telescopic direction. The two together ensure the smooth realization of the swinging action of the filter plate 41. The swing rod 44 is a component connecting the filter plate 41 and the eccentric wheel 45. One end is rotatably connected to the top surface of the filter plate 41, and the other end is rotatably connected to the eccentric wheel 45 through the internal rotating shaft, so that the rotational motion of the eccentric wheel 45 is converted into the swinging motion of the filter plate 41, so as to realize the dynamic filtering function of the filter plate 41. The eccentric wheel 45 rotates under the drive of the driving motor 6. , is the driving source of the entire filtering swing mechanism 4 movement, and drives the filter plate 41 to swing by cooperating with the swing rod 44. The gathering plate 51 is located below the filter plate 41, and its size is adapted to the processing chamber 1. The gathering groove opened inside is used to collect impurities that fall from the filter plate 41 and are subsequently pushed over, and plays a role of temporarily storing impurities, which is convenient for subsequent centralized cleaning. The pushing plate 52 is fixedly connected to the top of the gathering plate 51, and the inclined structures on both sides cooperate with the inclined blocks 53. When moving, it squeezes the inclined blocks 53 to realize its own action of pushing impurities. It is a direct pushing component in the process of cleaning impurities. The opposite side of the block 53 is in the shape of an inclined surface, which interacts with the inclined surface of the push plate 52. When the push plate 52 moves, it can move to both sides under the pressure of the push plate 52, providing a clearance and auxiliary effect for the push plate 52 to push the impurities, and can be restored to the initial position with the cooperation of the reset spring 54. One end of the reset spring 54 is connected to the inclined block 53, and the other end is connected to the inner wall of the processing chamber 1 through the straight plate 541, providing elastic support for the inclined block 53, so that the inclined block 53 can be restored to the initial position after being squeezed by the push plate 52, ensuring that the cleaning mechanism 5 can repeat the impurity cleaning work many times and maintain the cyclicity of the entire cleaning process.

[0036] The working principle and use process of the present invention are as follows: after the sampling pump is started, external air is drawn in and enters the processing chamber 1 through the output pipe. The air first contacts the filter plate 41 in the swing mechanism 4. The filter plate 41 has filter holes on its surface for filtering impurities, so that the impurities in the air are trapped above the filter plate 41. The filtered air continues to flow to the bottom of the processing chamber 1. At the same time, the drive motor 6 is started. The output end of the drive motor 6 is connected to the rotating block on the top surface of the eccentric wheel 45 through a spline, driving the eccentric wheel 45 to rotate. When the eccentric wheel 45 rotates, one end of the swing rod 44 passes through the inner The fixed rotating shaft is rotatably connected with the eccentric wheel 45, and the other end of the swing rod 44 is rotatably connected to the top surface of the filter plate 41, and two groups of telescopic springs 42 and telescopic columns 43 are symmetrically distributed at both ends of the filter plate 41. Driven by the rotation of the eccentric wheel 45, the swing rod 44 pushes the filter plate 41 to swing to a certain extent, and the telescopic spring 42 and the telescopic column 43 play the role of supporting the filter plate 41 and assisting its reset and buffering the swing. Through the swing of the filter plate 41, the impurities accumulated on the filter plate 41 can be distributed more evenly, avoiding local blockage of the filter holes, and ensuring continuous and stable filtering work;

[0037] As the filtering work continues, the filtered impurities will gradually gather on the filter plate 41, and some impurities will fall onto the collecting plate 51 below under the action of gravity. The size of the collecting plate 51 is adapted to the processing chamber 1, and a collecting groove is provided inside it to collect impurities that fall from the filter plate 41 and are subsequently pushed over. The restriction of the card block on the ring is pulled out, and at this time, the pressure on the reset spring 54 is contacted, and the reset spring 54 will drive the two inclined blocks 53 to move to both sides, and the inclined block 53 is separated from the push plate 52. The collecting plate 51 is pulled downward to clean the collected impurities.
