[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this utility model pertains. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but does not exclude other elements or objects.

[0026] This utility model provides a built-in buried negative pressure water supply device, including a stainless steel shell and a flow stabilizing component 1 and a water outlet component 2 disposed inside the stainless steel shell and connected to each other. The flow stabilizing component 1 is used to stabilize the pressure of the input water and is fixedly connected inside the stainless steel shell. The water outlet component 2 is used to boost the pressure of the water output.

[0027] See Figure 1 The built-in buried negative pressure water supply equipment needs to be partially buried underground. Sound insulation treatment can be applied to the equipment. In addition, water enters the flow stabilizing component 1 and the water outlet component 2 in sequence. The flow stabilizing component 1 stabilizes the water pressure, while the water outlet component 2 pressurizes the water.

[0028] In some embodiments, a fixing component 3 for mutual fixation is provided between the flow stabilizing component 1 and the water outlet component 2. The fixing component 3 includes a support base 31, a rotating buckle 32, and a fixing buckle. The support base 31 is fixed on the water outlet component 2, the fixing buckle is fixed on the flow stabilizing component 1, and the rotating buckle 32 is fixed on the support base 31 and can rotate and move. The rotating buckle 32 is made of a rigid and elastic material, and the fastening feature on the rotating buckle 32 engages with the fixing feature of the fixing buckle. The rotating buckle 32 is provided with a gripping arm to facilitate opening and closing of the rotating buckle 32.

[0029] See Figure 2 In practice, after the water outlet component 2 is damaged, the grip arm on the rotating buckle 32 can be firmly grasped and pried outwards to move the fastening feature on the rotating buckle 32 away from the fixing feature on the fixed buckle, thus making the water outlet component 2 movable. This allows for the replacement of the water outlet component 2. After replacing the water outlet component 2, the grip arm on the rotating buckle 32 is then grasped again to press the fastening part of the rotating buckle 32 into the fixing part of the fixed buckle, thus completely securing the water outlet component 2. Specifically, the rotating buckle 32 is made of a rigid yet elastic plastic material.

[0030] In some embodiments, the flow stabilizing component 1 includes a water storage tank 14, which is fixed inside a stainless steel shell by a connecting seat. The top of the water storage tank 14 is provided with a water inlet pipe for introducing external water into the water storage tank 14. The water storage tank 14 is used for temporary storage of water.

[0031] In fact, the water inlet pipe of the water storage tank 14 draws water from the water supply bureau into the water storage tank 14 for storage. When the water supply is insufficient, the water in the water storage tank 14 can be used to reduce the water supply pressure.

[0032] In some embodiments, the water storage tank 14 is equipped with a flow stabilizer, which is used to control the air pressure in the water storage tank 14 to remain constant.

[0033] In fact, when the water supply is insufficient, the water storage tank 14 will drain the water inside to allow users to continue using it. Since the water storage tank 14 is a closed space, a corresponding negative pressure will be generated when the water is drained. At this time, a flow stabilizer needs to be activated to introduce outside air into the water storage tank 14 to eliminate the negative pressure inside the water storage tank 14 and prevent backflow. In addition, the fact that the water storage tank 14 is a closed space can ensure that the water inside the water storage tank 14 is not contaminated by external substances.

[0034] In some embodiments, a liquid level sensor 11 is installed on the water storage tank 14 to monitor the liquid level in the water storage tank 14.

[0035] In fact, when the water supply is insufficient, the water tank 14 will drain the water inside, and the level sensor 11 will detect the drop in the water level of the water tank 14 to indicate that the flow stabilizer should be activated.

[0036] In some embodiments, the water storage tank 14 is provided with a water outlet pipe at the bottom, and the water outlet pipe is provided with a check valve 12 to stop the discharge of water.

[0037] In fact, when replacing the water outlet component 2, the stop valve 12 can be closed to prevent the liquid in the water storage tank 14 from flowing out and wasting water resources.

[0038] In some embodiments, the water outlet assembly 2 includes a water supply pipe 22, the inlet of which is connected to the water outlet pipe of the water storage tank 14, and the water supply pipe 22 of the water outlet assembly 2 is outside the water outlet pipe of the water storage tank 14, and the side of the water outlet pipe is in sliding contact with the side of the water storage tank 14.

[0039] In fact, the inlet of the water supply pipe 22 of the water outlet component 2 is connected to the outlet pipe 13 of the water storage tank 14, and the inlet of the water supply pipe 22 is installed outside the outlet pipe 13 of the water storage tank 14. Thus, when water is discharged from the outlet pipe 13 of the water storage tank 14 to the water supply pipe 22, it will not flow out of the water outlet component 2. In addition, the side of the water supply pipe 22 is in sliding contact with the side of the water storage tank 14 to ensure that the water supply pipe 22 is in a fixed state.

[0040] In some embodiments, a submersible pump 21 is provided inside the water supply pipe 22, and the submersible pump 21 is used to pressurize and discharge the water discharged from the water storage tank 14.

[0041] In fact, the submersible pump 21 is installed inside the water supply pipe 22, which can reduce the noise generated by the submersible pump 21, and the submersible pump 21 can pressurize the water and guide the discharged water to higher floors.

[0042] In some embodiments, the electrical conduit 17 connected to the water outlet assembly 2 is used to power the submersible pump 21 inside the water outlet assembly 2.

[0043] In fact, an electrical wire can be inserted into the conduit 17 to function as a submersible in the water supply pipe 22, and one end of the conduit 17 is connected to the outside, which can introduce outside air into the stainless steel shell to prevent negative pressure from being generated inside the stainless steel shell.

[0044] In some embodiments, the water storage tank 14 is made of stainless steel, which can ensure the quality of the output water and prevent rusting.

[0045] In fact, during long-term operation, the water storage tank 14 is made of stainless steel, which can prevent acid and alkaline substances in the water storage tank 14 from corroding the water storage tank 14 and thus polluting the water quality.

[0046] Although the embodiments of this utility model have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of this utility model as described in the claims. Moreover, the utility model described herein may have other embodiments and can be implemented or realized in various ways.
