[0003] To sum up: In the above case, the filter is used to prevent dust in the air from entering the device, but the filter is also prone to dust clogging after long-term use, which leads to low sensitivity of the smoke alarm. Utility Model Content

[0004] The purpose of the utility model is to provide a snap-on multifunctional fire alarm to address the deficiencies of the prior art, so as to solve the problem proposed in the above background technology that a filter is used to prevent dust in the air from entering the interior of the device, but the filter is also prone to dust clogging after long-term use, which leads to low sensitivity of the smoke alarm.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a snap-on multifunctional fire alarm, comprising a snap-on connection structure, a fire alarm structure is provided below the snap-on connection structure;

[0006] The snap-fit ​​connection structure comprises a connection plate with a through tube, and a connection cover with a hollow structure inside is fixed at the bottom of the connection plate, and a connection groove is formed through the surface of the connection cover;

[0007] Magnets for adsorbing fire alarm structure components are fixed inside the connection cover.

[0008] By adopting the above technical solution, the intercepting cover is provided to achieve the function of fixing and opening the device.

[0009] Preferably, the fire alarm structure comprises an installation shell in which a smoke sensing module and an alarm are respectively fixed, and horizontal fans are embedded and installed on both sides of the installation shell, and a through-hole body with a filter screen on the surface is fixed under the installation shell.

[0010] By adopting the above technical solution, the filter net is set to achieve interception and filtration.

[0011] Preferably, a connecting bearing is installed through the through-hole body, and a pushing plate is welded and fixed to the surface of the outer ring of the connecting bearing, and a bearing seat is fixed below the outer ring of the connecting bearing.

[0012] By adopting the above technical solution, the push plate is arranged to achieve force pushing and adjustment.

[0013] Preferably, a connecting rod is rotatably mounted in the bearing seat, and a detachable lint-removing roller is mounted on the surface of the connecting rod.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the card-type multifunctional fire alarm,

[0020] (1) This case solves the problem in the above case that the filter is used to prevent dust in the air from entering the interior of the device by means of the connecting bearing, the push plate, the bearing seat, the connecting rod and the lint-sticking roller set in the fire alarm structure. However, the filter is also prone to dust clogging after long-term use, which leads to low sensitivity of the smoke alarm. When dust adheres to the surface of the filter, the wind causes the push plate to rotate, driving the bearing seat, the connecting rod and the lint-sticking roller to rotate synchronously. When the lint-sticking roller rotates under force, the dust adhered to the surface of the filter is removed. The set filter not only prevents dust from easily clogging the through-hole body to reduce the sensitivity of the smoke sensing module, but also prevents the filter from being clogged and also has the above-mentioned problem.

[0021] (2) The horizontal fan provided in the fire alarm structure is used to convect smoke entering the installation housing and discharge it from the installation housing to prevent particles contained in the smoke from adhering to the surface of the smoke sensing module and reducing the sensitivity of the smoke sensing module;

[0022] (3) By providing: a snap-fit ​​connection structure, a connection seat, an iron block and a matching rod, the problem that the existing smoke alarm is installed in a fixed manner, resulting in the need for tools to disassemble the smoke alarm later, is solved. When the installation shell needs to be disassembled, the operator holds the through-hole body to drive the installation shell, the connection seat and the matching rod to rotate and separate from the connection groove. At this time, the operator pulls the through-hole body to separate the iron block from the magnet, and the installation shell is quickly disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 The utility model provides a technical solution: a card-type multifunctional fire alarm, such as Figure 1 and Figure 2 As shown, it includes a snap-fit ​​connection structure 1, which includes a connecting plate 101 with a through tube 102, and a connecting cover 103 with an internal hollow structure is fixed to the bottom of the connecting plate 101, and a connecting groove 104 is opened through the surface of the connecting cover 103, and there are three connecting grooves 104, and a single connecting groove 104 is set in an "L" shape. When the above structure has three grooves, it not only reflects the practicality of the setting of the above structure, but also reflects the matching snap-fit ​​connectivity of the setting of the above structure. When the above structure is set in an "L" shape, the above structure also reflects the rotation locking snap-fit ​​and rotation limiting connectivity of the matching rod 2014.

[0030] In the above solution, a magnet 105 for adsorbing the components of the fire alarm structure 2 is fixed inside the connection cover 103 .

[0031] In the above solution, the operator can use the fixing screws to penetrate the through-tube 102 to fix the connecting plate 101 at the corresponding installation position.

[0032] like Figure 3 and Figure 4 As shown, a fire alarm structure 2 is provided below the snap-fit ​​connection structure 1. The fire alarm structure 2 includes an installation shell 201 in which a smoke sensing module 202 and an alarm 203 are respectively fixed, and horizontal fans 204 are embedded and installed on both sides of the installation shell 201. At the same time, a through-hole body 205 with a filter screen 206 on the surface is fixed below the installation shell 201.

[0033] Furthermore, in the above scheme, a connecting bearing 207 is installed through the through hole body 205, and a push plate 208 is welded and fixed to the outer ring surface of the connecting bearing 207, and a bearing seat 209 is fixed under the outer ring of the connecting bearing 207, wherein the push plate 208, the connecting bearing 207 and the bearing seat 209 constitute a synchronous rotation adjustment structure, and the synchronous rotation adjustment structure constituted by the above components can effectively play a role in synchronous force rotation adjustment.

[0034] In the above scheme, a connecting rod 2010 is rotatably mounted in the bearing seat 209, and a detachable hair-removing roller 2011 is mounted on the surface of the connecting rod 2010.

[0035] In the above scheme, a connecting seat 2012 is fixed on the mounting shell 201 , and an iron block 2013 is fixed on the connecting seat 2012 . Meanwhile, a matching rod 2014 is fixed on the surface of the connecting seat 2012 .

[0036] In the above scheme, when the wind blows the push plate 208 to move under force, the push plate 208 drives the bearing seat 209, the connecting rod 2010 and the lint-sticking roller 2011 to rotate synchronously under force through the connecting bearing 207. At this time, the lint-sticking roller 2011 adheres to the dust on the surface of the filter screen 206. When the operator needs to remove the installation shell 201, the through-hole body 205 is rotated to separate the matching rod 2014 and the connecting groove 104 under force, and then the through-hole body 205 is pulled to separate the iron block 2013 from the magnet 105, and the overall installation shell 201 can be removed.
