[0031] The serial numbers of components used herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" in the present application, unless otherwise specified, include direct and indirect connection (coupling). In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0032] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the first feature, or simply indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the first feature, or simply indicate that the horizontal height of the first feature is less than that of the second feature.

[0033] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings in the specification and specific embodiments.

[0034] Reference Figure 1 and Figure 2 The main stream of the fire sprinkler adopts two different connecting rods 200 forms as shown in the figure, Figure 1 In the middle, the connecting rod 200 is connected to the center of the disc body 111, Figure 2 In the middle, the two connecting rods 200 are connected to the two sides of the disc body 111. The above two connecting rod 200 connection methods both have the problem of connecting rod 200 shielding water distribution, resulting in obvious dead angle of water distribution of the splash plate 100 in the first direction.

[0035] Reference Figure 3 is a way to detect the uniformity of water distribution of the fire sprinkler. Specifically, four sprinklers are placed at the four corners, and 6X6, a total of 36 water receiving boxes, are placed in the middle of the four sprinklers. Each water receiving box has a 0.5m*0.5m square water receiving surface. After the fire sprinkler sprays water for a period of time, the water quantity in the water receiving box is measured to see if the water quantity in the 36 water receiving boxes is uniform. In order to clarify the technical principles and effects of the present application, the 36 water receiving boxes are divided into A, B, C and D four areas, and the structure changes on the splash plate 100 and the effects of water distribution experiments are described in combination, in order to express simply and clearly.

[0036] Test the conventional circularly divided splash plate 100, in one test, the average water receiving amount of A area is 11.4L, the average water receiving amount of B area is 6.9L, the average water receiving amount of C area is 8.1L, the average water receiving amount of D area is 9.4L; the water distribution of the spray head through the splash plate 100 to A area is obviously too large, and the B area blocked by the connecting rod 200 is obviously less. Therefore, the water distribution effect of the traditional circularly divided splash plate 100 is not uniform, and the design needs to be changed to improve the water distribution uniformity of the spray head.

[0037] When used as a side wall spray head or as a splash plate 100 for water distribution in a specific direction, the outer contour of the disc body 11 can be semicircular, polygonal, strip-shaped, etc.

[0038] Regarding the connection form of the connecting rod 200 on the disc main body 111, it can be understood that, referring to Figure 1 and Figure 2 , the disc main body 111 can be centrally provided with a first connection position 12 for connecting the connecting rod 200, so that the disc main body 111 receives the downward orthogonal projection of the connecting rod 200; or it can also be designed that the disc main body 111 is provided with a second connection position 15 for connecting the connecting rod 200 on the opposite sides along the length direction.

[0039] In order to improve the effect of the disc main body 111 guiding water flow, the outer contour of the disc main body 111 includes a guide edge 1111 arranged along the length direction, and the guide edge 1111 is a straight edge parallel or substantially parallel to the first direction. It can be understood that the aforementioned straight edge can also be a substantially straight edge, allowing local or overall bending, which is within the concept of the straight edge described in the present application and includes the concept of the straight edge described in the present application.

[0040] Referring to Figure 4 , the structure of the traditional disc body 11', the existence of the connecting rod 200 causes a water distribution dead angle, which is a fan-shaped dead angle area, and the specific dead angle area is S1; referring to Figure 5 , the water distribution angle relative to the shielding area of the connecting rod 200 is changed based on the guide edge 1111, so that the area of the formed water distribution dead angle area S2 is smaller than S1, improving the uniformity of water distribution; referring to Figure 6 , and Figure 5 Similarly, both rely on the guide edge 1111 to change the water distribution angle, and the guide edge 1111 is appropriately inclined outward or inward, which can ensure that S2 is smaller than S1. The specific guide edge 1111 can be inclined outward at an angle α ≤ 10°, and the guide edge 1111 can be inclined inward at an angle β ≤ 10°. If the angle β is too small, a new water distribution dead angle will occur. It can be understood that the measurement reference line of the above-mentioned angles α and β is the center line X of the length of the disc main body 111.

[0041] The disc section 112, with reference to Figure 5 The disc section 112 is provided with two, two disc sections 112 are arranged on both sides of the width direction of the disc body 111, and the water is dispersed to the outside through the disc section 112. It can be understood that the disc section 112 and the disc body 111 can be a whole, such as a round piece processing.

[0042] The second water distribution groove 132, the second water distribution groove 132 is arranged on the disc section 112. With reference to Figure 5 The second water distribution groove 132 is arranged on the disc section 112, and the second water distribution groove 132 is arranged along the length direction of the disc body 111; or, with reference to Figure 7 The second water distribution groove 132 is arranged along the center ring of the disc body 111.

[0043] With reference to Figure 7 The width W1 of the second water distribution groove 132 and the arrangement density of the second water distribution groove 132 determine the width W2 of the convex part on the disc section 112, so as to determine the subdivision degree of the disc section 112 in each direction. If the W1 of the second water distribution groove 132 is small and the arrangement density of the second water distribution groove 132 is high, the disc section 112 can be distributed to each direction with a higher subdivision degree. In addition, since the disc body 111 also undertakes the water distribution to the first direction, in order to uniformly distribute the water, when there is a second water distribution groove 132 on the disc section 112, a first water distribution groove 131 can be arranged on the disc body 111, and based on the first water distribution groove 131 and the second water distribution groove 132, the water can be distributed more evenly.

[0044] With reference to Figure 8 The first water distribution groove 131 is arranged on the length direction of the disc body 111, and the first water distribution groove 131 is symmetrically arranged with respect to the length direction and the width direction of the disc body 111; or, the first water distribution groove 131 is symmetrically arranged with respect to the length direction and the width direction of the connecting rod 200 on the disc body 111. The setting of the first water distribution groove 131 is to balance the water distribution between the B area and the D area. The first water distribution groove 131 has a groove depth or a groove width, which is beneficial to reduce the water distribution to the B area and increase the water distribution to the D area; similarly, the first water distribution groove 131 has a shallow groove or a narrow groove, which is beneficial to increase the water distribution to the B area and reduce the water distribution to the D area.

[0045] It should be noted that the first water distribution groove 131 and the second water distribution groove 132 are arranged to uniformly distribute water in all directions. In addition, the water distribution grooves 13 can divide the disc body 11 into two parts with different distances from the center, so that the splash plate 100 can perform long-distance water distribution and short-distance water distribution, and the inner and outer circles can achieve uniform water distribution within the effective working range of the nozzle. Based on the uniform water distribution of the inner and outer circles, the width W1 of the second water distribution groove 132 is preferably the same as the width W2 of the protruding part on the disc part 112. The width W3 of the first water distribution groove 131 and the distance W4 between the first water distribution groove 131 and the connecting rod 200 are relatively close. In addition, the depths H2 of the first water distribution groove 131 and the second water distribution groove 132 also affect the distance of water distribution. If the depth of the groove is shallow, the short-distance water distribution is poor, and if the depth of the groove is deep, the local long-distance water distribution

[0046] Reference Figure 9 The splash plate 100 further comprises a flow limiting part 14, which is arranged at the second water distribution groove 132 in the middle region of the disc part 112, and the flow limiting part 14 is connected with the disc part 112. The flow limiting part 14 is arranged in the middle region of the second water distribution groove 132, and the flow limiting part 14 divides the second water distribution groove 132 into a first groove body 1321 and a second groove body 1322, and the first groove body 1321 and the second groove body 1322 are arranged at different distances from the disc main body 111.

[0047] In one embodiment, the width W5 of the flow limiting part 14 divides the second water distribution groove 132 with a groove depth H3 into a first groove body 1321 with a groove depth H4 and a second groove body 1322 with a groove depth H5. The relationship among the foregoing three determines the water distribution amount to the A area, and indirectly affects the remaining water distribution amounts. Such design can reduce the water distribution amount to the A area in experiments, and in the case of reduced water distribution amount to the A area, the water flow is dispersed to the B and C areas, which is more uniform as a whole. In addition, the water distribution amount to the D area is maintained or slightly increased. The specific position of the flow limiting part 14 in the second water distribution groove 132 can be adjusted according to experimental results.

[0048] Reference Figure 10 The flow limiting part 14 can also fill a part of the space (second groove body 1322) of the second water distribution groove 132, so that the second water distribution groove 132 only leaves a first groove body 1321. In addition, it can be understood that the first water distribution groove 131 and the second water distribution groove 132 can be designed as open grooves.

[0049] Reference Figure 11, the outer contour of the flow-limiting portion 14 includes a flow-limiting edge 141, which points or is basically pointed to both sides of the length direction of the disc body 111, improving the flow-limiting portion 14 to guide water to the B area. The flow-limiting portion 14 can be located in only one second water distribution groove 132, and the flow-limiting portion 14 can also be located in multiple second water distribution grooves 132, and the whole is directed to limit the water flow from the disc body 11 to the A area; when the flow-limiting portion 14 is specifically arranged in multiple water distribution grooves 13, the size contour of the flow-limiting portion 14 can also gradually decrease from the middle, so as to gradually reduce the blocking of the water flow moving out of the normal direction of the disc body 11, so as to achieve that the water flow change of each water receiving box is relatively gentle, and the water receiving amount of the adjacent water receiving box near the A area or the A area is avoided. Large differences occur.

[0050] Beneficial effects:

[0051] 1. In the present application, the part of the disc body 111 projected or connected by the receiving connecting rod 200 is set as the disc body 111, and the style and size of the disc body 111 are set to uniformly distribute water; specifically, by arranging the disc body 111 with a length direction greater than a width direction to guide the water falling into the water pan 100 to move in the length direction of the disc body 111, the water amount moving in the first direction blocked by the connecting rod 200 is increased relative to the traditional disc body 11', so as to increase the water distribution amount of the B area, so that the water sprayed by the fire nozzle is more uniformly distributed in all directions, and the water flow in the opposite direction is reduced due to the blocking of the connecting rod 200, thereby solving the technical problem of how to improve the water distribution uniformity of the water pan 100 in the prior art, and achieving the technical effect of improving the water distribution uniformity of the water pan 100.

[0052] 2. In the present application, the traditional disc body 11' structure of uniform distribution is broken, the first direction and / or the water distribution amount are adjusted based on the problem of the connecting rod 200 blocking water, and the disc part 112 is used to uniformly distribute water in all directions except the first direction, and the size relationship between the disc body 111 and the disc part 112 is controlled, so that the water distribution amount based on the disc body 111 flowing to the first direction and the water distribution amount based on the disc part 112 flowing to the remaining directions are close, and the actual effect of uniform water distribution is further achieved.

[0053] 3. In the present application, the water distribution amount in each direction on the disc section 112 is further limited by the flow limiting portion 14. Specifically, the flow limiting portion 14 is arranged at the second water distribution groove 132 in the middle region of the disc section 112, so that the problem of excessive water distribution in the A zone in the shower test is solved. Further, the flow limiting edge 141 is directed or substantially directed to the two sides of the length direction of the disc main body 111, so that the flow limiting portion 14 not only limits the water flow to be distributed outward from the second water distribution groove 132 in the middle region of the disc section 112, but also guides the water flow to the first direction which is blocked by the connecting rod 200. As a result, the water distribution amount in the A zone is reduced, and the water distribution amounts in the B zone and the C zone and the D zone near the B zone are increased in the shower test. In addition, based on the above, the size of the flow limiting portion 14 and the size of the disc main body 111 can guide the water flow to the connecting rod 200. In a specific design, the width of the disc main body 111 can be reduced, and the width of the flow limiting portion 14 can be increased to compensate. Alternatively, the width of the disc main body 111 can be increased, and the width of the flow limiting portion 14 can be reduced.

[0054] 4. In the present application, the water flow is guided by the guide edge 1111 of the disc main body 111 to be discharged at an angle parallel or substantially parallel to the first direction, so as to reduce the actual shielding angle of the connecting rod 200 to the water distribution, reduce the water distribution dead angle caused by the connecting rod 200, and increase the water distribution amount to the B zone. Specifically, the guide length and the inclination angle of the guide edge 1111 relative to the first direction comprehensively determine the guiding ability of the water flow. The guide length and the inclination angle of the guide edge 1111 can be designed comprehensively to be adjusted flexibly.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0056] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the spirit and scope of the present application. Thus, it is intended that the present application embrace all such modifications and changes and, accordingly, the application is not to be construed as limited to the preferred embodiments.
