[0035] The specific implementation of the present application will be further described in detail in combination with the drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0036] As Figs. 1 to 4The utility model provides a kitchen fire extinguishing system's auxiliary foam spraying equipment of stove, it is different from the prior art in that: in order to have better spraying height according to the overall height of current stove, cooking utensil, vertical distribution has the bearing column 2 on the positioning base plate 1. Meanwhile, vertical equidistance distribution has several mounting holes 3 on the bearing column 2, and the spraying pipe 4 is arranged on the mounting hole 3 through the limiting assembly. That is to say, the spraying pipe 4 can select the appropriate mounting hole 3 to install according to the actual spraying coverage, improve the versatility of the bearing column 2. For example, for the pot, select the middle, low hole installation, if subsequent mainly is to carry out the cooking and needs to cooperate the higher cooking utensil, then can select the higher hole installation. During implementation, the front end of the spraying pipe 4 is provided with a flow guide assembly, which can make the foam finally distribute to the fire extinguishing area required by the stove, and can well isolate and cover the fire source. Considering the butt joint with the foam pressurized feeding equipment in the fire extinguishing system, the rear end of the spraying pipe 4 is connected with the feeding pipe 5 through the restraint assembly 15, and the feeding pipe 5 is in communication with the spraying pipe 4. In order to avoid abnormal shaking caused by the flow impact of the foam medium during feeding, a limiting buckle 6 can be arranged on the positioning base plate 1, and the feeding pipe 5 is embedded in the limiting buckle 6. Furthermore, the positioning base plate 1 is also provided with several connection assemblies 7. In this way, it can be more convenient to fix to the table or support on the side edge of the stove, and stable installation can be realized.

[0037] In combination with a preferred embodiment of the utility model, the positioning base plate 1 is welded with the bearing column 2, and has better integral rigidity. Meanwhile, the positioning base plate 1 is mirror-imaged distributed with several connection holes on both sides of the bearing column 2, and the connection assembly 7 is arranged in the connection hole. In this way, the bottom multi-point positioning is satisfied. During implementation, the both sides of the bearing column 2 are mirror-imaged distributed with the folded blocking edge 8. Thus, the contact area of the bottom of the bearing column 2 can be increased, and more stable combination can be realized. Moreover, such a structure can make the cross section of the bearing column 2 present a "concave" shape, and has better anti-deformation effect.

[0038] Further, the mounting hole 3 is an oval hole, and the silica gel gasket 9 is arranged in the mounting hole 3. In this way, the spraying pipe 4 can be better pre-positioned, and it is convenient to lock through the limiting assembly subsequently. During use, the limiting assembly adopted includes several nuts 10, the spraying pipe 4 is provided with external threads, and the nut 10 is threadedly connected to the front and rear of the spraying pipe 4 and clamps the bearing column 2. In this way, after final locking, the spraying pipe 4 can have better combination integrality with the bearing column 2, and the spraying pipe 4 will not be loose due to the stress impact of spraying during spraying. Meanwhile, such a combination mode is convenient to adjust and operate, and improves the assembly efficiency.

[0039] In combination with actual implementation, the adopted flow guide assembly includes an annular buckle 11 arranged at the front end of the spray pipe 4, and the annular opening is connected with a spray baffle 12 through locking screws, and the spray baffle 12 is a circular arc plate. In this way, for medium and large cooking stoves and utensils, the foam sprayed from the front end of the spray pipe 4 is reflected by the spray baffle 12 and falls into the position of the cooking stove and the utensil, thereby realizing centralized fire extinguishing and preventing scattering due to excessive pressure during spraying.

[0040] For small cooking stoves, the following method can also be provided, that is, a flow guide assembly composed of a spray head 13 is arranged at the front end of the spray pipe 4. The spray head 13 is provided with a plurality of arrayed nozzles. At the same time, the spray head 13 is provided with a turning adjusting section 14, and the turning adjusting section 14 is provided with a locking spring buckle. The combination mode of the spray head 13 is similar to that of the commonly used spray system, and thus will not be described here. In this way, the orientation of the spray head 13 can be adjusted according to the actual shape of the utensil, and a better foam coverage area is obtained. After adjustment, the locking spring buckle is automatically locked. It should be noted that the locking spring buckle adopts a commonly used spring lock buckle with a self-locking function on the market, and a self-locking adjusting pipe or other structures can also be used. As long as the assembly can realize the angle adjustment and locking of the spray head 13, it can be adopted, and thus will not be described here.

[0041] Further, the binding assembly 15 is a tie, which synchronously wraps the joint of the feeding pipe 5 and the spray pipe 4. In this way, the joint is stabilized to prevent loosening. At the same time, a plurality of raw material belts or waterproof belts can be wound at the joint to improve the liquid tightness. Finally, a binding iron wire is provided outside the tie to realize the final locking. In this way, even if subjected to the impact of high-pressure foam liquid, the joint will not loosen.

[0042] Furthermore, the connection assembly 7 is a positioning screw or a rivet to stably connect with the positioning hole arranged on the side of the cooking stove or the support.

[0043] The working principle of the utility model is as follows:

[0044] After the related equipment of the kitchen fire extinguishing system triggers the fire extinguishing instruction, the foam pressurized feeding device operates to spray the fire extinguishing foam to the cooking stove and the utensil through the corresponding flow guide assembly. In this way, the open fire of the cooking stove and the oil fire in the utensil can be comprehensively extinguished.

[0045] As can be seen from the above description and in combination with the drawings, the utility model has the following advantages:

[0046] 1. The installation height of the spray pipe can be selected according to the type of the cooking stove and the utensil to ensure better spray coverage range and prevent dead angles.

[0047] 2. It is provided with independent flow guide assembly, can realize the fine adjustment of final spraying coverage, and is convenient for on-site layout adjustment.

[0048] 3. The feeding pipe is combined with the spraying pipe stably, and will not appear loose in use, can effectively bear the stress brought by spraying.

[0049] 4. The whole structure is simple, is convenient for on-site layout, can adapt to the needs of current conventional kitchen fire extinguishing system, and can make up the needs of non-top spraying fire extinguishing layout.

[0050] In addition, the indicated direction or position relationship described in the utility model is the direction or position relationship shown based on the drawings, is only for the convenience of describing the utility model and simplifying the description, and is not for indicating or implying that the indicated device or structure must have a specific direction, or is operated in a specific direction structure, thus cannot be understood as the limitation of the utility model.

[0051] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, and it should be pointed out that, for ordinary skilled person in the art, on the premise of not departing from the technical principle of the utility model, can make several improvements and modifications, and these improvements and modifications should be regarded as the protection range of the utility model.
