Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0036] As Figures 1-3 shown, the present utility model provides a BAS sensor with a dust-proof sticker, including a BAS sensor body and a dust-proof sticker 4. The dust-proof sticker 4 is attached to the BAS sensor body to seal a plurality of ventilation holes and interfaces on the BAS sensor body.
[0037] Further, as Figure 1 shown, the BAS sensor body includes a housing 1, a main board 2, and a bottom cover 3. The main board 2 is arranged and installed in the inner chamber of the housing 1. The bottom cover 3 covers the bottom of the housing 1 and is snap-fitted and fixed thereto. The bottom cover 3 encapsulates the main board 2 in the inner chamber of the housing 1.
[0038] Further, the upper surface of the main board 2 is regularly provided with a transmitting channel 201, a diffusion chamber 202, and a receiving channel 203. The transmitting channel 201 and the receiving channel 203 are arranged in a V-shaped layout, and the diffusion chamber 202 is arranged between the transmitting channel 201 and the receiving channel 203.
[0039] Among them, a transmitting tube for emitting an infrared light source is provided at the head end of the transmitting channel 201, and a receiving tube for receiving the infrared light source is provided at the tail end of the receiving channel 203. In order to improve the light source utilization rate of the transmitting tube and the light source collection amount in the receiving channel, one or more lenses 204 are regularly arranged and installed in the transmitting channel and the receiving channel.
[0040] Further, a PCB board is regularly arranged below the main board 2. The pins of the transmitting tube and the receiving tube pass through the main board 2 and are welded to the pads on the PCB board below it.
[0041] Further, an upper ventilation grille 101 is regularly provided on the housing 1. The upper ventilation grille 101 is composed of a number of ventilation holes regularly arranged. The upper ventilation grille 101 is arranged above the diffusion chamber 202 and conducts the diffusion chamber to the external environment. The diffusion chamber 202 is conducted to the external environment through the upper ventilation grille 101.
[0042] Further, a lower ventilation grille is regularly provided on the bottom cover 3. The lower ventilation grille is arranged below the diffusion chamber to connect the diffusion chamber with the external environment channel. The diffusion chamber can also be conducted to the external environment through the lower ventilation grille.
[0043] Therefore, the aerosol suspension particles in the external environment can be diffused into the diffusion chamber 202 through the upper and lower ventilation openings of the upper ventilation grille and the lower ventilation grille, thereby increasing the diffusion speed of aerosol and other suspension particles and improving the detection sensitivity of the BAS sensor.
[0044] As Figure 1 shown, since the transmitting channel 201, the diffusion chamber 202, and the receiving channel 203 are arranged between the upper surface of the main board 2 and the inner wall of the housing 1. For this reason, in order to facilitate the conduction between the lower ventilation grille and the diffusion chamber 202 above the main board, a lower ventilation boss 301 is regularly provided at the upper end inside the bottom cover 3 at the position of the lower ventilation grille. The lower ventilation boss 301 is vertically penetrated to form a lower ventilation port 3011.
[0045] Further, the lower ventilation boss 301 sequentially passes through the PCB board and the main board 2 and extends into the diffusion chamber 202. The PCB board and the main board 2 are provided with an insertion port 205 for facilitating the passage of the lower ventilation boss. The lower ventilation boss 301 extends into the diffusion chamber 202 through the insertion port 205 and is communicated with the diffusion chamber 202 through the lower ventilation port 3011.
[0046] Further, for the convenience of communication and data transmission, the main board 2 is also regularly provided with an interface 206. The interface 206 is electrically connected to the PCB board through a plurality of PIN pins.
[0047] Among them, as Figure 1 shown, in one embodiment, the interface 206 is arranged on the right side of the main board 2 and extends out of the right side panel of the housing 1.
[0048] Further, an interface slot 103 for facilitating the extension of the interface 206 is arranged on the right side panel of the housing 1. The interface 206 is snapped into the interface slot 103 to extend out of the housing 1, so as to facilitate electrical connection with an external data terminal.
[0049] Further, in order to improve the stability of the interface 206 in the interface slot 103 and avoid the shaking of the interface 206. The front, rear, left and right four sides of the bottom cover 3 extend upward to form a bottom cover baffle 302. The interface pressure plate 303 is regularly arranged on the bottom cover baffle on the right side of the bottom cover. The interface pressure plate 303 is snapped into the interface slot 103 together with the interface 206, so as to press the interface 206 upward and stably fix it in the interface slot 103.
[0050] Further, for the convenience of the assembly work of the BAS sensor, the main board 2 is first installed on the bottom cover 3 and then installed into the housing 1 together with the bottom cover 3. Therefore, for the convenience of installing the main board 2 on the bottom cover 3, the lower end of the main board 2 is regularly provided with a main board insertion plate 207 extending downward. Correspondingly, a main board slot 304 for facilitating the insertion of the main board insertion plate 207 is regularly arranged on the bottom cover 3 at the position of the main board insertion plate 207. The main board 2 is quickly inserted into the main board slot 304 through the main board insertion plate 207, so as to be quickly installed on the bottom cover 3.
[0051] Further, in order to improve the stability of the main board 2 installed on the bottom cover 3, a plurality of positioning posts are regularly arranged on the bottom cover 3. Correspondingly, a plurality of positioning holes for facilitating the passage of the plurality of positioning posts are regularly opened on the PCB board and the main board 2 at the positions of the plurality of positioning posts on the bottom cover.
[0052] Further, the bottom cover 3 is installed on the lower end surface of the housing 1, and the bottom cover 3 is snap-fitted and fixed to the housing 1. As Figure 1As shown, the front and rear sides of the housing 1 are provided with a plurality of bayonet holes 104, and correspondingly, the front and rear sides of the bottom cover 3 are provided with upwardly protruding elastic hooks 306 at the positions of the plurality of bayonet holes 104. The elastic hooks 306 on the front and rear sides of the bottom cover 3 are inserted upward along the inner walls of the front and rear sides of the housing 1, and cooperate with the bayonet holes 104 on the front and rear sides of the housing to clamp and fix them together.
[0053] Furthermore, in order to better insert and install the bottom cover into the lower end of the shell 1, a positioning plate 305 is extended upwardly on the rear end card of the bottom cover. Through the fool-proof design of the positioning plate 305, the front and back sides of the bottom cover can be quickly distinguished, thereby improving the assembly efficiency of the product.
[0054] Furthermore, in order to facilitate the installation and fixation of the BAS sensor, a fixing seat 102 is extended outward from the upper end surface or the front and rear side surfaces of the housing 1, and fixing holes 1021 for fasteners to pass through are regularly arranged on the fixing seat 102.
[0055] like Figures 1-3 As shown, the dustproof sticker 4 is used to seal the upper ventilation grille 101, the interface 206 and the lower ventilation grille of the BAS sensor, so as to prevent external dust and foreign objects from falling into the diffusion chamber, the transmitting channel and the receiving channel inside the BAS sensor, and entering the interface 206 to affect communication and data transmission.
[0056] The dustproof sticker 4 includes an upper sealing area 401, an interface sealing area 402 and a lower sealing area 403 which are sequentially arranged from front to back. The upper sealing area 401, the interface sealing area 402 and the lower sealing area 403 are integrally designed from front to back.
[0057] Furthermore, the upper sealing area 401 extends forward to the front of the upper ventilation grille 101 and completely seals the upper ventilation grille; the interface sealing area 402 completely seals the interface 206; and the lower sealing area 403 extends backward to the rear of the lower ventilation grille and completely seals the lower ventilation grille.
[0058] Furthermore, a non-glue prying piece area 4011 for conveniently tearing off the dustproof sticker 4 is regularly arranged extending outward from the front end of the upper sealing area 401 , and the entire dustproof sticker 4 can be conveniently and quickly peeled off through the prying piece area 4011 .
[0059] Furthermore, the front end of the lower sealing area 403 is also regularly provided with a positioning opening 4031, which is arranged at the end of the interface sealing area 402 and the head end of the lower sealing area 403. The positioning opening 4031 facilitates the dustproof sticker to be regularly and quickly attached to the BAS sensor, and completely seals the upper ventilation grille, the interface and the lower ventilation grille.
[0060] like Figure 1 and Figure 2As shown, the front end of the positioning port 4031 is the junction of the interface sealing area 402 and the lower sealing area 403. The dustproof sticker 4 can be quickly connected to the BAS sensor body through the positioning port 4031. The front end of the positioning port is aligned with the lower end of the right side of the BAS sensor, so that the upper ventilation grille, the interface and the lower ventilation grille can be completely sealed with a minimum of dustproof sticker material to better save materials.
[0061] Of course, the positioning opening can also be set at the end of the upper sealing area 401 and at the junction with the interface sealing area 402.
[0062] The utility model adopts an integrated dustproof sticker design, and only one dustproof sticker is needed for one BAS sensor to completely seal all the vents and interfaces on the BAS sensor, thereby avoiding the problem of missing stickers.
[0063] At the same time, the integrated dust sticker extends from the vent at the top of the BAS sensor to the vent at the bottom and wraps around the side interface. It has a large adhesive area, many attachment points, strong adhesion, and is not easy to fall off. The sensor product will not have problems with warping or falling off during long-term storage and transportation.
[0064] At the same time, the integrated dust sticker can completely cover and seal all the vents and interface holes on the sensor. If the integrated dust sticker is not removed, the sensor product cannot be installed and used normally. This can also avoid the problem that the detection performance of the sensor product deteriorates or even cannot be detected because the dust sticker is not removed after the product is installed. Through the integrated design, all the vents and interface holes of the sensor can be exposed at one time.
[0065] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
