An insulating snap assembly 130 according to an embodiment of the invention is described in detail below with reference to fig. 1-34.
As shown in fig. 22-28, an insulating snap assembly 130 according to an embodiment of the invention includes: at least one first insulating clip 131 and a second insulating clip 132.
Specifically, as shown in fig. 22 to 27, the first insulating clip 131 includes a first body 1311, at least two first engaging legs 1312, and a first hook 1313. As shown in fig. 22 and 23, the first engaging leg 1312 extends downward from the lower end of the first body 1311, and the first hook 1313 extends upward from the upper end of the first body 1311. Therefore, the first insulating clip 131 can be reliably connected between the two members by the first engaging leg 1312 and the first hook 1313, thereby simplifying the structure of the first insulating clip 131 and improving the assembling efficiency. It should be noted that the first insulating clip 1313 may be made of a material having insulating properties, and two components connected by the first insulating clip 131 are not electrically conductive, so that the use requirement between different components can be met.
As shown in fig. 28, the second insulating clip 132 includes: a second body 1321, a second hook 1323, and a boss 1324. The second body 1321 is hollow, the top of the second body 1321 has an opening 1325 and the bottom is open, the two opposite sides of the outer surface of the second body 1321 extend outward to form second engaging legs 1322, the second hook 1323 extends downward from the sidewall of the second body 1321 between the two second engaging legs 1322, and the boss 1324 extends upward from the top of the second body 1321. Therefore, the second insulating clip 132 can be reliably connected between the two components by using the second engaging pin 1322, the second hook 1323 and the boss 1324, thereby simplifying the structure of the second insulating clip 132 and improving the assembly efficiency. Likewise, the second insulating clip 132 may be made of a material having insulating properties, and two components connected by the second insulating clip 132 are not electrically conductive, so that the use requirements between different components can be satisfied.
According to the insulating buckle assembly 130 of the embodiment of the invention, the first insulating buckle 131 can be reliably connected between two components by using the first engaging leg 1312 and the first hook 1313 on the first insulating buckle 131, and the second insulating buckle 132 can be reliably connected between two components by using the second engaging leg 1322, the second hook 1323 and the boss 1324, so that the structure of the first insulating buckle 131 is simplified, and the assembly efficiency is improved.
In an embodiment of the invention, the first body 131 and the second body 132 have a coupling greater than or equal to 2 mm. In the example shown in fig. 22 and 28, the height of the first body 131 is 2mm or more and the height of the second body 132 is 2mm or more in the up-down direction. Thus, the first insulating snap 131 can space two parts apart when connecting the two parts; likewise, the second insulating snap 132 may also space two components apart when connecting the two components.
As shown in fig. 23 and 24, in order to improve the structural strength of the first insulating clip 131, a reinforcing rib 1314 is connected between the first body 1311 and the first engaging leg 1312. In the example shown in fig. 24, the reinforcing ribs 1314 may be plural, and the reinforcing ribs 1314 are distributed at intervals on the outer peripheral wall of the first body 1311. Preferably, the reinforcement rib 1314 is a triangular reinforcement rib, a first side of the triangular reinforcement rib is connected to the first body 1311, and a second side of the triangular reinforcement rib is connected to the first snap foot 1312.
Further, in one example of the present invention, the first snap foot 1312 includes three. For example, as shown in fig. 23 and 27, three first engaging legs 1312 are arranged at the lower edge of the first body 1311 at intervals. Therefore, the structural strength of the first insulating clip 131 can be further improved, and the structure of the first insulating clip 131 can be more compact and reasonable. Preferably, there are two strengthening ribs 1314 corresponding to two of the three first snap pins 1312.
As shown in fig. 23, 25, and 27, the first body 1311 has a through hole 1315 penetrating the first body 1311 in the up-down direction. In other words, the first body 1311 may be formed in a cylindrical shape, and thus, the structure of the first insulating clip 131 may be further simplified, the mass of the first insulating clip 131 may be reduced, and the production cost may be reduced, while ensuring the structural strength of the first insulating clip 131.
As shown in fig. 23, in one embodiment of the present invention, the upper end surface of the first body 1311 includes: a first segment 1316, a second segment 1317, and a connecting segment 1318. Wherein the first section 1316 is located at a side away from the first hook 1313, and the first section 1316 is located in a horizontal plane. The second section 1317 is disposed on a side near the first hook 1313, and the second section 1317 is disposed in another horizontal plane below the first section 1316. The connecting section 1318 is connected between the first section 1316 and the second section 1317. In other words, the distance between the connecting section 1318 and the first hook 1313 increases from bottom to top. Therefore, when the first hook 1313 is connected to other components, the connection section 1318 can play a guiding role, so that the first insulating buckle 131 is connected to other components, and the assembling efficiency of the first insulating buckle 131 is improved.
As shown in fig. 28, in one embodiment of the present invention, the cross-section of the second body 1321 in the up-down direction has a square shape. Therefore, the structural strength of the second insulating fastener 132 can be improved, and the structure of the second insulating fastener 132 can be more compact and reasonable.
In the example shown in fig. 28, a guide curved surface 1326 is formed between the side wall of the opening 1325 and the upper end surface of the second body 1321. Thus, the guiding cambered surface 1326 has a guiding function to facilitate the matching connection of other components with the second insulating buckle 132. The shape of the opening 1325 is not particularly limited, and for example, in a preferred example of the present invention, the opening 1325 may be formed as a square hole as shown in fig. 28.
Further, as shown in fig. 28, the second engaging leg 1322 is provided at a position adjacent to the lower end of the side wall of the second body 1321, the side wall of the second body 1321 located below the second engaging leg 1322 is formed as a guide portion 1327, and the cross-sectional area of the guide portion 1327 in the up-down direction is gradually reduced from top to bottom. Accordingly, the second engaging leg 1322 can be guided to engage with another member by the guide portion 1327, and the assembling efficiency between the second insulating clip 132 and another member can be improved.
Further, as shown in fig. 28, a guiding inclined surface 1328 is provided between the lower end surface of the second hook 1323 and the side wall of the second hook 1323. From this, be convenient for second trip 1323 and other part cooperations, and then improved the assembly efficiency of second insulating buckle 132.
As shown in fig. 28, in a preferred example of the present invention, the boss 1324 has a rectangular cross section in the up-down direction, and the cross sectional area of the boss 1324 in the up-down direction gradually increases from top to bottom. Thereby facilitating mating of the boss 1324 with other components.
As shown in fig. 1 to 4, a dust collection assembly 100 according to an embodiment of the present invention includes: a first annular ring 110, a second annular ring 120, and an insulating snap assembly 130. Wherein, as shown in fig. 2, the dust collection assembly 100 can be connected to a high voltage power supply 500 during use, a high potential terminal of the high voltage power supply 500 is electrically connected to one of the first and second annular rings 110 and 120, and a low potential terminal of the high voltage power supply 500 is electrically connected to the other. For example, in one example of the present invention, the high potential terminal is electrically connected to the first annular ring 110 through a first electrical connection 113, and the low potential terminal is electrically connected to the second annular ring 120 through a second electrical connection 123. After the first annular ring 110 and the second annular ring 120 are connected with the high-voltage power supply 500, a high-voltage direct-current electric field is formed between any two adjacent surfaces on the first annular ring 110 and the second annular ring 120 which are spaced apart.
It should be noted that the high voltage direct current electric field ionizes gas molecules in the air to generate a large amount of electrons and ions, the electrons and the ions move towards the two poles under the action of the electric field force, and the charged particles touch dust particles and bacteria in the air flow to charge the dust particles and the bacteria in the air flow in the moving process, and the charged particles move towards the opposite pole plate with the air flow under the action of the electric field force. Under the action of the electric field, free ions in the air move towards the two poles, and the higher the voltage and the higher the electric field strength, the faster the movement speed of the ions is. As a result of the movement of the ions, a current is formed between the electrodes. At the beginning, there are fewer free ions in the air and less current. When the voltage rises to a certain value, ions near the discharge electrode obtain higher energy and speed, and when the ions strike neutral atoms in the air, the neutral atoms are decomposed into positive and negative ions, and the phenomenon is called air ionization. After the air is ionized, a chain reaction is generated, so that the number of ions moving between electrodes is greatly increased, which is shown as the sharp increase of the current (called as corona current) between the electrodes, therefore, the air becomes a conductor, the high-voltage catches the attached bacterial particles, and the cell wall composed of protein is instantaneously conductively punctured, thereby achieving the purposes of killing bacteria, adsorbing and removing dust.
Specifically, the first annular ring 110 has a first outer ring 111 and a plurality of first blades 112 circumferentially provided on an inner surface of the first outer ring 111. Optionally, first blades 112 are sheet-like and extend in a radial direction of first outer ring 111. The first annular ring 110 is further provided with a first connection terminal 117, and the first connection terminal 117 is provided radially outside the first outer ring 111.
The second annular ring 120 has a second outer ring 121 and a plurality of second blades 122 circumferentially provided on an inner surface of the second outer ring 121. As shown in fig. 1-4, the second annular ring 120 is disposed below the first annular ring 110, and the plurality of second blades 122 are circumferentially staggered from the plurality of first blades 112. The second annular ring 120 is further provided with a second connection terminal 127, and the second connection terminal 127 is provided radially outside the second outer ring 121. Thus, a plurality of high voltage dc electric fields can be formed between the first and second annular rings 110 and 120, thereby improving dust removal efficiency of the dust collection assembly 100.
In addition, an airflow channel is formed between the adjacent first blades 112 and second blades 122, and the first blades 112 and second blades 122 which are staggered in the circumferential direction have a rectifying effect on the airflow passing through the dust collection assembly 100, so that the uniformity of the airflow is enhanced, the air inlet pressure and the resistance during flowing of the airflow are further reduced, and the noise generated during flowing of the airflow is further reduced.
The first annular ring 110 has a first electrical connection 113 adapted to be connected to one of the positive and negative poles of the electrical power supply, the first electrical connection 113 being provided on the first connection terminal 117, the second annular ring 120 has a second electrical connection 123 adapted to be connected to the other of the positive and negative poles of the electrical power supply, the second electrical connection 123 being provided on the second connection terminal 127. Thereby, a reliable connection of the first and second annular rings 110, 120 to the high voltage power supply 500 may be ensured by the first and second electrical connections 113, 123. When the dust collecting assembly 100 is connected to the high voltage power supply 500, dust, particles, etc. in the air flow passing between the first annular ring 110 and the second annular ring 120 will be captured by the high voltage dc electric field and adsorbed onto the surface of the first annular ring 110 or the second annular ring 120, thereby achieving the purpose of dust removal.
An insulating snap assembly 130 is disposed between the first and second annular rings 110, 120 and disposes the first and second annular rings 110, 120 in a spaced apart relationship. In other words, the insulating snap assembly 130 is supported between the first annular ring 110 and the second annular ring 120 such that any point on the first annular ring 110 is not in direct contact with the second annular ring 120. Therefore, when the dust collecting assembly 100 is in use, a high-voltage electric field is formed between the adjacent surfaces of the first annular ring 110 and the second annular ring 120, and the effects of dust collection and sterilization of the dust collecting assembly 100 are further achieved. Preferably, the insulating snap assembly 130 is detachably connected to both the first annular ring 110 and the second annular ring 120, thereby facilitating a user to wipe and clean the dust collection assembly 100 when the dust collection assembly 100 needs to be cleaned.

Meanwhile, the reliability of the connection between the first annular ring 110 and the second annular ring 120 is improved, the structure of the dust collection assembly 100 is simplified, and the assembly efficiency is improved.
According to one embodiment of the present invention, the shortest distance between the first annular ring 110 and the second annular ring 120 is 2mm or more. In other words, the distance between any point on the first annular ring 110 and the second annular ring 120 is greater than or equal to 2 mm. To ensure that the shortest distance between the first annular ring 110 and the second annular ring 120 is 2mm or more, the first body 131 and the second body 132 have a height of 2mm or more.

In the example shown in fig. 11, 17-27, at least two first engaging pins 1312 are disposed on the positioning posts 1211 to connect the first body 1311 with the second outer ring 121. As shown in fig. 26, the first engaging legs 1312 abut against the lower end surfaces of the positioning pillars 1211, so that the positioning pillars 1211 are limited between at least two first engaging legs 1312. To facilitate the connection of the first insulating clip 131 with the first outer ring 111, the first clip 1313 extends upward from the upper end of the first body 1311 and is clipped to the edge of the first outer ring 111 to connect the first body 1311 with the first outer ring 111.

Therefore, the structural strength of the first insulating buckle 131 can be improved, and the structure of the first insulating buckle 131 is more reasonable.
Further, as shown in fig. 4, the first insulating clips 131 are three and are uniformly distributed in the circumferential direction of the first annular ring 110. Thereby, the connection reliability between the first annular ring 110 and the second annular ring 120 can be ensured.
To facilitate the connection of the first and second annular rings 110 and 120 to the high voltage power supply 500, a first electrical connector 113 is provided at an end of the first connection terminal 117, and a second electrical connector 123 is provided at an end of the second connection terminal 127. Further, in order to prevent the first connection terminal 117 from contacting the second connection terminal 127, as shown in fig. 3 to 4, and 28 to 29, a second insulation clip 132 is provided between the first connection terminal 117 and the second connection terminal 127 to connect the first connection terminal 117 and the second connection terminal 127 with a space therebetween. Therefore, a certain distance can be kept between the first connecting terminal 117 and the second connecting terminal 127, and the air between the first connecting terminal 117 and the second connecting terminal 127 is not broken down and does not generate electric discharge when the dust collection assembly 100 is in the working state, so that the stability and the safety of the dust collection assembly 100 are ensured.

Thus, by clamping the second clamping leg 1322 and the second clamping hook 1323 in the second clamping hole 1271, the movement of the second insulating clamp 132 along the circumferential direction of the second clamping hole 1271 can be limited; by abutting the second engaging leg 1322 against the upper surface of the second connection terminal 127 and abutting the second hook 1323 against the lower surface of the second connection terminal 127, the movement of the second insulating clip 132 in the axial direction of the second engaging hole 1271 can be restricted, and the connection reliability of the second insulating clip 132 with the first connection terminal 117 and the second connection terminal 127 can be improved.

At the same time, the compactness of the dust collection assembly 100 may be further improved. Further, as shown in fig. 5 and 7, the upper surfaces of the second blades 122 are all flush and located on the same plane. Thus, the structure of the dust collection assembly 100 can be more neat and compact.
