Detailed Description
The invention is further described with reference to the following figures and detailed description.
A pressurized shower head, referring to fig. 1 to 5, comprising an upper cover 1, a lower cover 2, a hand-held part 3, wherein the upper cover 1 and the hand-held part 3 are integrally formed; the upper cover 1 is fixedly connected with the lower cover 2; the lower cover 2 is close to the handheld part 3 and is provided with an air inlet 21 along the water outlet direction; a water stop piece is arranged at the position, opposite to the air inlet 21, of the upper cover 1, an air inlet cavity 23 is formed between the water stop piece and the lower cover 2, and the air inlet cavity 23 is communicated with the air inlet 21; a negative pressure cavity 24 is also arranged between the upper cover 1 and the lower cover 2, and the negative pressure cavity 24 is communicated with the air inlet cavity 23; an air inlet groove 11 is formed in the position, close to the handheld part 3, of the upper cover 1 along the water outlet direction; the air inlet groove 11 is communicated with the negative pressure cavity 24 and a water inlet waterway.
The principle is simply introduced as follows: when water flows through the air inlet groove 11, the water flow is increased, the pressure of the negative pressure cavity 24 is reduced, and air enters the air inlet hole 21 and enters the water inlet waterway through the negative pressure cavity 24 and the air inlet groove 11.
Specifically, the upper cover 1 and the lower cover 2 are tightly connected to form a closed cavity 12; the water flows out from the water outlet waterway through the closed cavity 12. The water stop member is specifically a baffle 13, the baffle 13 is specifically a baffle 13 arranged along the horizontal direction, and the baffle 13 is blocked between the air inlet 21 and the closed cavity 12; a gap is formed between the baffle 13 and the lower cover 2 to form the air inlet cavity 23, and the length direction of the air inlet cavity 23 is perpendicular to the hole depth direction of the air inlet hole 21. The upper cover 1 is provided with a cavity upper wall 14, the cavity upper wall 14 is also arranged in the horizontal direction, a cavity distance is formed between the cavity upper wall 14 and the lower cover 2 to form the negative pressure cavity 24, and the length direction of the negative pressure cavity 24 is parallel to the length direction of the air inlet cavity 23. The cavity distance is greater than the gap between the baffle 13 and the lower cover 2. The gas inlet groove 11 is formed between the cavity upper wall 14 and the baffle 13 at a certain distance along the water outlet direction, and a blocking part is further extended above the cavity upper wall 14 along the direction close to the baffle 13, so that the gas inlet route forms a route indicated by an arrow in fig. 5, and the gas inlet groove also has a certain water-stop function, and prevents water from flowing to the gas inlet hole 21 from the closed cavity 12.
The specific principle is as follows: when water flows from the water outlet waterway to the closed cavity 12, according to the venturi effect, when the water passes through the air inlet groove 11, the water flow speed of the water flow at the air inlet groove 11 is increased because the air inlet groove 11 is too narrow, so that the negative pressure cavity 24 is in a negative pressure state; at the moment, air enters the closed cavity 12 from the air inlet 21, specifically enters the closed cavity 12 from the air inlet 21, then reaches the negative pressure cavity 24 through the air inlet cavity 23, then flows to the closed cavity 12 through the air inlet groove 11, and then is mixed with water flow to form bubble water, and then flows out from the water outlet 22; form the whole in-process of bubble water, because the existence of baffle 13, rivers can not flow through inlet port 21, avoid causing water waste and influence user experience. The baffle 13 is simple in structure and easy to obtain, is different from other complex non-return mechanisms, greatly reduces the manufacturing cost of the product, and effectively improves the market competitiveness of the product. Meanwhile, the air inlet 21 is arranged at the position closest to the water outlet channel, namely the water passes through the air inlet groove 11 before reaching the water outlet hole 22, at this time, the speed of the water flow is the maximum, the formed negative pressure effect is also the best, and the air can be sucked into the air inlet 21 more quickly to form bubble water.
In addition, in order to optimize the spray effect of the water spray sprayed from the water outlet holes 22, a plurality of water outlet holes 22 are formed in the lower cover 2 along the water outlet direction to form a water outlet hole group. The diameter of the water outlet hole 22 gradually increases from the water outlet direction. The air inlet 21 is arranged at one side of the water outlet group close to the handheld part 3.
The above description is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any person skilled in the art can make insubstantial changes in the technical scope of the present invention within the technical scope of the present invention, and the actions infringe the protection scope of the present invention are included in the present invention.
