[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0039] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the utility model should be the common meanings understood by people with ordinary skills in the field to which the disclosure belongs.

[0040] As can be understood from the foregoing description, conventional security alarms are usually provided with a screen, which is used to allow the detected smoke to enter the body, to dissipate the heat generated when the body is working, and to prevent flying insects and dust from entering the body.

[0041] Traditional security alarms are mostly installed at height, such as on rooftops, so they do not require maintenance during their service life. However, the screens that are designed to block insects and dust from entering will cause insects and dust to adhere to their outer surface, which will prevent the smoke that needs to be sensed from entering.

[0042] In order to at least partially solve the above-mentioned problems and one or more of other potential problems, an exemplary embodiment of the utility model proposes a security alarm, which can prevent flying insects and dust from adhering to the shielding body 21 by vibrating the shielding body 21 (i.e., the shielding net) under the connecting frame 23 composed of the first base 231, the second base 232 and the contraction part 233 under the resistance, such as the airflow generated by the passage of people, and prolonging the vibration time; or prevent flying insects and dust from adhering to the shielding body 21 by vibration generated by the vibration source 4 under the connecting frame 23 composed of the first base 231 and the second base 232.

[0043] The following combination Figure 1-Figure 5 The security alarm is exemplified. Figure 1 It is a front view plan view of the utility model. Figure 2 It is a front view and a top view of the source access and sound amplification part 2 of the utility model. Figure 3 For this utility model Figure 2 A partial enlarged plan view of the . Figure 4 It is a plan view comparing the front view and top view of the source access and sound amplification part 2 of some embodiments of the utility model. Figure 5 For this utility model Figure 4 The security alarm comprises an alarm part 1 and a source access and amplifying part 2 located on the alarm part 1; the alarm part 1 is used to emit sound and / or light prompt sounds according to the detected source (i.e. smoke or other gases), and the source access and amplifying part 2 is located on the opening of the alarm part 1, so as to prevent other substances except the detected source and air from entering the alarm part 1.

[0044] Furthermore, the source access and sound amplification part 2 includes a shielding body 21 (i.e., a shielding net), which can vibrate on the alarm part 1, thereby preventing the blocked flying insects and dust from adhering to the shielding body 21 for a long time under the action of vibration, which allows smoke to enter the alarm part 1 through the shielding body 21 at any time.

[0045] Regarding the alarm part 1, it includes a mounting base 11, a housing 12 connected to the mounting base 11, a sensor source, an alarm source and a power supply located in the housing 12 (not shown in the figure but can be understood through the subsequent description), and the through port is opened on the housing 12;

[0046] The mounting base 11 is not only used to support the housing 12, but also used to connect to a plane that needs to be fixed, such as a roof, through a bolt assembly or a snap-fit ​​structure, so as to limit the installation alarm to a high place so as not to interfere with the daily life of people in the community.

[0047] The housing 12 is used to protect the core parts inside, such as the sensor source, alarm source and power supply, etc., wherein:

[0048] The sensing source is used to detect whether the gas entering the housing 12 is the detected source, specifically, to detect whether the gas entering the housing 12 is smoke that needs to be alarmed, and if so, to send an electrical signal to the alarm source; the alarm source is used to send or not send a sound and / or light prompt sound according to the detection situation of the sensing source; the power supply is used to power the sensing source and the alarm source;

[0049] The through opening (not shown in the figure but understandable through the subsequent description) is specifically opened in the top central part of the shell 12, so that the smoke passing through the shield 21 continues to pass through the through opening and enter the shell 12, and is detected by the sensor source.

[0050] In some embodiments, a control source is also included to perform the functions of the above steps (this is a relatively mature technology and will not be explained in detail here).

[0051] Regarding the protective body 21, it includes: a frame (not shown in the figure), an outer protrusion 211 wrapped around the frame and protruding outward (the specific height of the outer protrusion is determined according to the actual application and is not limited here), and a flange 212 integrally connected to the edge of the outer protrusion 211, and the size of the flange 212 can cover the opening; specifically, when the outer protrusion 211 of the protective body 21 is aligned with the opening on the outer shell 12, the diameter of the flange 212 is larger than the diameter of the opening to cover the opening, thereby preventing flying insects or other large particles or dust from entering the opening.

[0052] In some embodiments, it further includes: a bracket 22 which is integrally connected to the frame and protrudes from the outer protrusion 211, and has a diameter smaller than that of the outer protrusion 211;

[0053] At least six connecting frames 23 (the number is not limited to six, and can be an even number of six or more, for example, eight) are equidistantly located between the bracket 22 and the outer shell 12 on the circumference, and this number of connecting frames 23 include: a first base 231, which is located on the outer shell 12; a second base 232, which is connected between the first base 231 and the bracket 22; wherein the first base 231 and the second base 232 are connected to form a curved shape that is at least greater than a right angle, so that the protective body 21 is limited to the opening of the outer shell 12 under the connecting action of the connecting frame 23.

[0054] Further, in some embodiments, the number of connecting frames 23 all include: a contraction portion 233, which is integrally connected between the first base 231 and the second base 232, so that the shielding body 21 can be elastically vibrated and located on the outer shell 12, so that substances other than the detected source and air can stay on the shielding body 21 for a long time. Specifically, it can be understood that the area of ​​the contraction portion 233 is smaller than the first base 231 and the second base 232, and the supporting strength of the contraction portion 233 of the number of connecting frames 23 is limited to be smaller than the shielding body 21, so that the shielding body 21 is easily vibrated by external resistance such as airflow, and the vibrating shielding body 21 will shake off the dust attached to its outer surface, thereby ensuring that smoke can enter the security alarm at any time. It should be noted that: in order to make the shielding body 21 very easy to vibrate, there is a small gap between the shielding body 21 and the top of the outer shell 12, so that the shielding body 21 is not affected by the friction resistance of the outer shell 12.

[0055] In some embodiments, the number of connecting frames 23 is at least four (the number is not limited to four, and can also be more than four, such as five or six). In this embodiment, the connecting frame 23 is still composed of a first base 231 and a second base 232 and has the same shape as an embodiment (see above), but the difference from the previous embodiment is that the first base 231 is gradually connected to the second base 232 as a whole, which results in the protective body 21 being stably placed on the opening of the outer shell 12 under the connection of the connecting frame 23, that is, it will not vibrate due to slight external resistance such as airflow.

[0056] Based on the previous embodiment, it further includes: a shield 3, which is located on the outer protrusion 211 and connected to the frame, and a storage space is formed between the interior of the shield 3 and the outer protrusion 211; a vibration source 4 is provided in the storage space, and the vibration source 4 is used to generate vibration and transmit it to the shielding body 21, so that the shielding body 21 can be vibrated and located on the outer shell 12, thereby shaking off the dust attached to the outside of the shielding body 21.

[0057] In some embodiments, the vibration source 4 can be a vibration motor or other mechanisms, structures or devices that can generate and control vibration.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
