Description

Technical Field

[0001] This utility model relates to the field of police equipment technology, and in particular to a multi-functional duty umbrella. Background Technology

[0002] Existing umbrellas are made of ordinary materials and generally lack cut-resistant, impact-resistant, and strike-resistant features, making them unsuitable for use as warning equipment. Police officers, when performing their duties, carry a limited variety of police equipment with insufficient protective coverage and strength. When suddenly attacked by someone wielding a knife, axe, or club, or when needing to subdue an enemy, they are often injured due to inadequate protection. In rainy weather, if police officers are performing their duties, they typically wear raincoats or multi-functional uniforms, making it inconvenient to carry police equipment.

[0003] To address the above problems, a novel multifunctional anti-riot umbrella is disclosed in the prior art. A tear gas sprayer and a braking element are installed within the cavity of the umbrella handle. The front end of the tear gas sprayer has a thin tubular nozzle. When the nozzle is pressurized and pushed inwards towards the tear gas sprayer, irritating tear gas is sprayed from the nozzle. The nozzle of the tear gas sprayer corresponds to the spray hole on the gas adapter. When the tear gas sprayer is pushed forward by the braking element, the edge of the spray hole abuts against the nozzle, causing it to contract inwards. The gas sprayed from the nozzle is then ejected through the spray hole. A conduit is fitted at the front end of the spray hole, and the other end of the conduit is connected to the end of the umbrella handle, through which the gas is ejected.

[0004] The applicant has discovered that the prior art has at least the following technical problems:

[0005] The existing multi-functional anti-riot umbrella has a relatively complex structure in its handle, making it inconvenient to replace and install tear gas sprayers.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] like Figures 1-4As shown, this utility model provides a multi-functional service umbrella, including a front handle 1 and a tear gas sprayer 11; the front handle 1 has a cavity inside for accommodating a part of the tear gas sprayer 11; one side of the front handle 1 is open for insertion of the tear gas sprayer 11; the tear gas sprayer 11 includes a nozzle 10 and a canister 12; the nozzle 10 has a push-button switch that can spray when the push-button switch is pressed; the nozzle 10 is inserted into the cavity in a pluggable manner, and when the nozzle 10 is inserted into the front handle 1, the front handle 1 and the canister 12 are joined together to form the entire handle of the umbrella; in use, police officers hold the handle for rain and sun protection; to facilitate spray control in emergency situations, in this embodiment, the front handle 1 is provided with a tactile marking structure 8, and when the nozzle 10 is inserted into the cavity, its push-button switch faces the marking structure 8.

[0037] It should be noted that in this embodiment, the tear gas spray 11 has the same structure as the tear gas spray 11 equipped by police officers in the prior art. The only difference is that the diameter of the canister part 12 of the tear gas spray 11 in this utility model is equal to the diameter of the front handle 1, so that when the spray head 10 is inserted into the front handle 1 and the front handle 1 and the canister part 12 are joined together, a cylindrical handle can be formed. The spray head 10 should be a frustum-shaped structure with a small taper, so that the outer diameter of the spray head 10 is smaller than the inner diameter of the front handle 1, while the diameter of the rear section of the spray head 10 should be equal to the inner diameter of the front handle 1. With this structural setting, it is easy to form a tight fit between the rear section of the spray head 10 and the front handle 1 after insertion, thereby preventing the tear gas spray 11 from falling off, and allowing the tear gas spray 11 to be pulled out from the front handle 1 when pulled forcefully. This invention only improves the external shape and specifications of the tear gas sprayer 11. The push-button switch and spraying structure remain unchanged, employing existing structural features; therefore, they will not be elaborated upon here. The specifications for the tear gas sprayer 11 are: spray distance ≥ 4 meters, spray time ≥ 5 seconds, and operating temperature -30℃ to 55℃ (push-button, mist, water). For example, the tear gas sprayer 11 (tear gas sprayer) can be a water-based type from the Green Pudding series.
