Technical Field

[0001] The utility model relates to the technical field of assembled smoke hoods, in particular to a fire sprinkler structure for assembled smoke hoods. Background Art

[0002] A range hood is an electrical appliance used in the kitchen. Its main function is to exhaust the fumes, smoke and odors generated during cooking to the outside through an air suction device, so as to keep the kitchen air clean and reduce the impact of fumes on the human body. A range hood usually includes an exhaust fan and a fume filtration system. The range hood plays an important role in purifying the air and protecting health in the kitchen. It is one of the indispensable equipment in modern family kitchens.

[0003] Fume hood is a kind of equipment used in kitchens, laboratories and other places, mainly used to remove oil smoke and harmful gases. In order to prevent fire in the hood, it is often necessary to install a fire sprinkler structure in the hood to extinguish the fire.

[0004] There are some problems with the traditional smoke hood fire sprinkler structure. First, the installation position is limited and it cannot effectively cover the entire area inside the smoke hood. Second, it is inconvenient to operate and it is impossible to flexibly control the opening and closing of the sprinkler head.

[0005] Therefore, we propose an assembled smoke hood fire sprinkler structure to solve the problems in the above background. Utility Model Content

[0009] The fire sprinkler structure comprises a sprinkler head, the upper part of which is connected to a fire pipe, and the upper part of each sprinkler head is connected to two fire pipes, one of which is equipped with a solenoid valve switch, and the other is equipped with a manual valve.

[0010] Preferably, a protective sleeve is fixedly connected to the upper portion of the sprinkler head, and the protective sleeve is sleeved on the outside of the two fire-fighting pipes.

[0011] Preferably, the manual valve penetrates to the outside of the protective sleeve, and a turning handle is installed at one end of the manual valve located outside the protective sleeve.

[0012] Preferably, the smoke hood mechanism includes an integrated frame, a side frame, a panel frame, a top plate, a support beam, a filter plate, a partition plate and reinforcing ribs, and the various structures of the smoke hood mechanism are detachable.

[0013] Preferably, there are two groups of fire sprinkler structures, and the two sprinkler heads are respectively arranged on both sides of the smoke hood mechanism.

[0014] Preferably, the partition is installed at the bottom of the front end of the smoke hood mechanism, and the sprinkler head is installed at the bottom of the partition.

[0015] Preferably, a temperature sensor is installed on the surface of the partition, and a control module is externally connected to the temperature sensor, and the control module is electrically connected to the solenoid valve switch.

[0016] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0017] First, the utility model can effectively extinguish fire and prevent fire from spreading by installing a fire sprinkler structure at the bottom of the front end of the smoke hood mechanism. The temperature is monitored by a temperature sensor, and the opening and closing of the solenoid valve switch are adjusted by a control module. Two fire pipes are arranged on the sprinkler head, one with a solenoid valve switch and the other with a manual valve. The fire sprinkler can be automatically or manually controlled as needed. The double switch control improves the flexibility and safety of operation.

[0018] Second, the utility model can monitor the temperature change of the smoke hood mechanism in real time by installing a temperature sensor on the surface of the partition and connecting it to the control module. When the temperature exceeds the set value, the control module can automatically control the solenoid valve switch to start the fire sprinkler, and promptly prevent the fire from spreading, thereby improving the efficiency and safety of fire disposal. By providing a turning handle between the manual valve and the protective sleeve, it is convenient for the operator to control the manual valve, thereby improving the convenience and accuracy of operation. By splitting and installing the various structures of the smoke hood mechanism, it is convenient to manufacture, transport and install, thereby improving the operability and convenience of the smoke hood mechanism. By providing two groups of fire sprinkler structures, the range of the entire smoke hood mechanism can be better covered, thereby improving the effect and safety of fire extinguishing. By installing the partition at the bottom of the front end of the smoke hood mechanism and installing a sprinkler head at its bottom, the fire sprinkler structure can be better combined with the smoke hood mechanism, thereby improving the sprinkler effect and safety.
