As shown in fig. 1 and 2, the present invention provides a technical solution: the utility model provides a pressure boost water outlet equipment, includes shell 1, and wherein, the inside cavity formation of shell 1 holds the chamber, holds the intracavity setting and is provided with the booster pump. The booster pump comprises a pump body 5, a motor 6 and an impeller 12. And a water inlet section 4 and a water outlet section 17 are arranged outside the pump body 5. The water inlet section 4 is used for leading water flow into the inner cavity 10, and the water outlet section 17 is used for leading out the water flow in the inner cavity. The water inlet section 4 is positioned at the bottom of the shell 5, and the motor 6 is positioned at the top of the shell 5.

And a water outlet 3 is formed in the left side of the bottom of the inner cavity 10 of the booster pump. The water outlet section 17 is communicated with the water outlet 3.

As shown in fig. 3, the water inlet section 4 is provided with a water inlet 2, a check valve 8 and a water flow switch 7 in sequence from left to right, and the water flow is prevented from being poured back through the check valve 8;

as shown in fig. 3 and 9, a booster pump inner cavity 10 is arranged inside the pump body 5, and an injection mechanism 9 is arranged in the middle of the booster pump inner cavity 10, and is arranged in the inner cavity 10 of the pump body to divide the inner cavity into a first cavity 18 and a second cavity 19.

In the present embodiment, the ejector mechanism 9 has an hourglass shape, as shown in fig. 8, and includes a tapered runner end 25, a tapered upper portion, and a tapered lower portion. Wherein the tapered upper and lower portions have a larger diameter and the tapered flow channel end 25 has a smaller diameter, the tapered flow channel end 25 being located between the tapered upper and lower portions. The expanded portion of the spraying means 9 contributes to the separation of the water from the air, and in addition the depression of the spraying means 9 contributes to the circulation of the whole water flow;

as shown in fig. 3 and 9, the first inlet end 20 of the first chamber 18 is communicated with the inner end of the inlet section 4, and the outlet end 21 of the first chamber 18 is communicated with the impeller 12. After entering the inner chamber from the water inlet end 4, water enters the first chamber 18 from the water inlet section 4 at the inner end of the pump body 5. And then flows from the first outlet end 21 of the first chamber 18 to the impeller 12.

As shown in fig. 3 and 9, a circulation mechanism 11 is disposed at the right side of the bottom of the inner chamber 10 of the booster pump, wherein the circulation mechanism 11 forms a circulation channel 24, a second water inlet end 22 of the circulation channel 24 is communicated with the second chamber 19, and a second water outlet end 23 of the circulation channel 24 extends to a first water inlet end 20 of the first chamber 18. That is, when the circulation mechanism 11 makes water sprayed from the spraying mechanism 9 and sprayed to the impeller 12, part of the water enters the circulation mechanism 11 and then enters the spraying mechanism 9 again;

as shown in fig. 5 and 8, the top end of the injection mechanism 9 is provided with a sealing ring 16 to be connected with a hole at the top end of the inner cavity 10 of the booster pump, the bottom end of the injection mechanism 9 is provided with a sealing ring 16 to be connected with the tail end of the water inlet section 4, and water leakage is effectively prevented through the sealing ring 16.

As shown in fig. 5 and 6, the circulation mechanism 11 is provided with a threaded cap 14 and a valve rod 13 in sequence from right to left, and the right end of the valve rod 13 is nested inside the threaded cap 14, so that the valve rod can be conveniently detached during maintenance through the provided threaded cap 14.

The water inlet of the circulating mechanism 11 is positioned at the bottom of the inner cavity 10 of the booster pump, the water outlet of the circulating mechanism 11 is positioned in the tail end of the water inlet section 4 and is positioned on the same axis with the injection mechanism 9, and circulation of water flow is achieved conveniently.

The left side of valve rod 13 is equipped with sealing washer 16, the valve rod 13 left end is equipped with the spring, and spring one end supports and leans on the left end portion of valve rod 13, and the other end of spring supports and leans on the casing 5 inboard and corresponding with the left end portion of valve rod 13.

Through setting up the spring, after booster pump inner chamber 10 air has all been discharged or booster pump inner chamber 10 has been full of water, the water pressure of booster pump inner chamber 10 reached the setting value this moment, and spring force can be overcome to valve rod 13 this moment for the inside delivery port of circulation mechanism 11 is supported on valve rod 13 top, and the booster pump accomplishes the pressure boost operation.

That is, in this embodiment, the circulation mechanism 11 functions as a "backflow valve", when the booster pump cavity 10 is in a full water state, the motor 6 and the impeller 12 work and generate suction to the water inlet cavity of the booster pump cavity 10, when the spring elastic force is designed to be large, the backflow valve cannot be closed due to large elastic force (that is, the top end of the valve rod 13 does not abut against the water outlet inside the circulation mechanism 11), and at this time, the injection mechanism 9 realizes circulation pressurization by adopting the injection pump principle; until the water is sucked to the water inlet cavity of the inner cavity 10 of the booster pump without air or reaches the set pressure, the pump can be completely boosted, and after the water cavity of the inner cavity 10 of the booster pump reaches a certain pressure, the reflux valve is closed due to the pressure of the water outlet cavity (the top end of the valve rod 13 is propped against the water outlet inside the circulating mechanism 11), so that the effect of the booster pump is formed.

As shown in fig. 5, the motor 6 is nested in the upper end of the housing 5, and the output end of the motor 6 is provided with an impeller 12, so that the impeller 12 rotates, thereby effectively utilizing the water flow pressurization effect of the impeller. Through the design of the injection mechanism 9 and the circulating mechanism 11, the water flow is pressurized by the impeller 12 regularly, only part of water is impacted by the impeller 12 at each time, and therefore the pressurizing effect is good. Because the power of the household booster pump is generally small, the design is applied to the household booster pump to better realize the boosting effect.

As shown in fig. 2, the front surface of the booster pump casing 1 is provided with a heat radiation hole 15, the water inlet 2 is positioned at the lower right corner of the left side surface of the booster pump casing 1, and the water outlet 3 is positioned at the lower right corner of the front side surface of the booster pump casing 1.

The working principle of the embodiment is as follows: when the booster pump is used, water is firstly added into an inner cavity 10 of the booster pump (the water inlet 2 is provided with the check valve 8 which can prevent the water from flowing out of the water inlet 2), and water flows into the water inlet 2, sequentially passes through the check valve 8 and the water flow switch 7 and enters the contraction part of the injection mechanism 9; when the inner cavity 10 of the booster pump is in a full water state, the water pump is started, and the motor 6 and the impeller 12 start to work; then the water can be sprayed to the impeller 12 at a high speed, and in the process that the water is sprayed to the impeller 12 (namely, in the jet flow process), the water in the inner cavity 10 of the booster pump enters the water inlet of the spraying mechanism 9 along with the jet flow, and negative pressure is formed in the inlet water; the water in the cavity 10 of the booster pump is automatically sucked to the other end of the injection mechanism 9, so that the self-suction effect is achieved (namely, the injection pump principle), and the separation of the water and the air is facilitated through the expansion part on the injection mechanism 9;

in the process that water in a water inlet cavity of an inner cavity 10 of the booster pump is boosted to a water outlet cavity (meanwhile, a part of air of the water inlet 2 enters the water inlet cavity) by the motor 6 and the impeller 12, initially, the circulating mechanism 11 (namely a reflux valve) is in an open state under the action of the spring, so that the water in the water outlet cavity can flow back to the water inlet cavity;

therefore, water enters the injection mechanism 9 from the circulation mechanism 11, internal circulation of the water is realized, the pressure of water flow is further improved, the air content is minimized, the other part of the water flows out from the water outlet 3, when the inner cavity 10 of the booster pump is filled with water or reaches a specified pressure, the valve rod 13 moves, the circulation mechanism 11 is closed, and at the moment, the water entering from the water inlet 2 flows to the inner cavity 10 of the booster pump through the injection mechanism 9 and then flows out from the water outlet 3.

[ example two ]

In the first embodiment, the spring force is large, so that pressurization can be realized by adopting the jet pump principle at the initial stage, while in the present embodiment, under the condition that the spring force is small, the inner cavity 10 of the booster pump is full of water, the motor 6 and the impeller 12 work to have suction force on the water cavity of the inner cavity 10 of the booster pump, the corresponding valve rod 13 is also subjected to the suction force at the moment, the valve rod 13 can overcome the spring force easily, and the return valve is in a closed state at the moment; when the water inlet cavity is lack of water and needs to be self-sucked, the suction force on the valve rod 13 is reduced, the valve rod 13 is far away from the water outlet inside the circulating mechanism 11 under the action of the spring, the reflux valve is in an open state at the moment, the water outlet cavity supplies water to the water inlet cavity, after a certain amount of water is supplied, the pump can be pressurized again, the reflux valve is in a closed state again, and water flows out from the water outlet 3; the process is circulated, so that the self-priming effect of the self-priming pump is achieved.

Therefore, the invention can realize the pressurization effect when the spring has large elasticity and small elasticity, adopts a mechanical structure to realize pressurization in the whole process, is externally connected with other components and has simple and effective structure.
