Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to a box-type negative pressure-free water supply equipment. Background Technology

[0002] Negative pressure-free water supply equipment is a type of pressurized water supply unit that is directly connected to the municipal water supply network and uses series superimposed pressure to ensure that the pressure of the municipal network is not less than the set protection pressure.

[0003] Most existing box-type negative pressure-free water supply devices lack pre-filtration during use. When water enters the inside of the tank, impurities are carried into the tank and tend to accumulate inside the tank or pipes, which can easily cause blockages or affect the quality of subsequent water inside the tank. Therefore, this utility model proposes a box-type negative pressure-free water supply device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that most existing box-type negative pressure water supply equipment lacks pre-filtration, which causes impurities to be carried into the inner side of the water tank after the water enters the tank, easily accumulating inside the tank or pipes, causing pipe blockage or affecting the subsequent water quality inside the tank. Therefore, this utility model proposes a box-type negative pressure water supply equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A box-type negative pressure-free water supply device, including

[0007] Water tank;

[0008] A water inlet pipe, which is located at the top of the water tank;

[0009] A base plate, which is fixedly installed on the right side of the water tank;

[0010] A negative pressure-free water pump, which is fixedly installed on the top of the base plate;

[0011] The water outlet pipe is fixedly connected to the negative pressure-free water pump.

[0012] A disassembly mechanism and an installation mechanism, wherein the disassembly mechanism cooperates with the installation mechanism;

[0013] The filtration mechanism includes: a housing, a sealing plate, and three activated carbon plates;

[0014] The outer shell is fixedly installed on the top of the water tank. The top of the outer shell is fixedly connected to the water inlet pipe. The outer shell is connected to both the water inlet pipe and the water tank. All three activated carbon plates are fixedly connected to the sealing plate. All four activated carbon plates and the sealing plate are in sliding contact with the inner wall of the outer shell.

[0015] As a preferred embodiment of this utility model, the disassembly mechanism includes: a handle frame, two insertion plates, and a connecting plate;

[0016] The handle is fixedly connected to the cover plate, the insertion plate is slidably connected to the outer shell, and the connecting plate is fixedly connected to the two insertion plates.

[0017] As a preferred embodiment of this utility model, the installation mechanism includes: a push rod, a rotating frame, a pressing frame, and a cooperating rod;

[0018] The push rod is rotatably connected to the rotating frame and the connecting plate respectively. The rotating frame is rotatably connected to the top of the outer shell. The rotating frame and the pressing frame are in sliding contact. The mating rod is fixedly installed on the top of the outer shell. The pressing frame and the rotating frame are in sliding contact.

[0019] As a preferred embodiment of this utility model, the top of the connecting plate is fixedly installed with symmetrically arranged springs, and both springs are fixedly installed on the top of the outer shell.

[0020] As a preferred embodiment of this utility model, vertical grooves are provided on the rear sides of both insertion plates, and symmetrically arranged sliding blocks are fixedly installed on the front side of the outer shell, with the sliding blocks slidably connected to the inner wall of the vertical grooves.

[0021] As a preferred embodiment of this utility model, a rectangular groove is provided on the top of the handle frame, and the bottoms of the two insertion plates slide in contact with the inner wall of the rectangular groove. Beneficial effects

[0022] 1. After the insert plate is inserted into the inside of the handle bracket, the insert plate can prevent the sealing plate from separating from the outer shell. In addition, the insert plate will also prevent the sealing plate from tilting inside the outer shell through the handle bracket, so as to stably seal the outer shell.

[0023] 2. After the pressing frame is pressed, the pressing frame can rotate the rotating frame, causing the side of the rotating frame away from the mating rod to move upward. The rotating frame can then push the push rod, which in turn pushes the connecting plate upward. This causes the connecting plate to move the two insert plates upward and stretch the two springs. The two insert plates can then detach from the handle frame and move to the top front position of the cover plate. At this point, the sealing plate can be tilted using the handle frame. First, the bottom of the sealing plate can be removed, and then the entire sealing plate can be pulled out, bringing the activated carbon plate out with it. This allows for the disassembly and replacement of the activated carbon plate.

[0024] In this invention, by installing a shell between the water inlet pipe and the water tank, the water entering the inside of the water tank is filtered by the activated carbon plate inside the shell, thereby reducing impurities entering the tank and preventing the water quality inside the tank from being affected.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0031] Reference Figures 1-4 A box-type negative pressure-free water supply device, including

[0032] Water tank 1;

[0033] Water inlet pipe 2 is located at the top of water tank 1;

[0034] Base plate 4 is fixedly installed on the right side of water tank 1;

[0035] The negative pressure-free water pump 5 is fixedly installed on the top of the base plate 4;

[0036] Water outlet pipe 6 is fixedly connected to negative pressure-free water pump 5.

[0037] The disassembly mechanism and the installation mechanism work together;

[0038] The filtration mechanism includes: a housing 3, a sealing plate 7, and three activated carbon plates 8;

[0039] The outer shell 3 is fixedly installed on the top of the water tank 1. The top of the outer shell 3 is fixedly connected to the water inlet pipe 2. The outer shell 3 is connected to the water inlet pipe 2 and the water tank 1 respectively. The three activated carbon plates 8 are all fixedly connected to the sealing plate 7. The four activated carbon plates 8 and the sealing plate 7 are all in sliding contact with the inner wall of the outer shell 3.

[0040] With the above structure, by installing the outer shell 3 between the water inlet pipe 2 and the water tank 1, the water entering the inside of the water tank 1 will be filtered by the activated carbon plate 8 inside the outer shell 3, thereby reducing impurities entering the inside of the tank and preventing the water quality inside the water tank 1 from being affected.

[0041] As a preferred embodiment of the present invention, the disassembly mechanism includes: a handle 9, two insertion plates 10 and a connecting plate 11;

[0042] The handle 9 is fixedly connected to the cover plate, the insertion plate 10 is slidably connected to the outer shell 3, and the connecting plate 11 is fixedly connected to the two insertion plates 10. After the insertion plate 10 is inserted into the inside of the handle 9, the insertion plate 10 can prevent the sealing plate 7 from separating from the outer shell 3. In addition, the insertion plate 10 will also prevent the sealing plate 7 from tilting inside the outer shell 3 through the handle 9, so as to stably seal the outer shell 3.

[0043] As a preferred embodiment of the present invention, the installation mechanism includes: a push rod 13, a rotating frame 14, a pressing frame 15, and a cooperating rod 16;

[0044] The push rod 13 is rotatably connected to the rotating frame 14 and the connecting plate 11 respectively. The rotating frame 14 is rotatably connected to the top of the outer shell 3. The rotating frame 14 is in sliding contact with the pressing frame 15. The mating rod 16 is fixedly installed on the top of the outer shell 3. The pressing frame 15 is in sliding contact with the rotating frame 14. After the pressing frame 15 is pressed, the pressing frame 15 can press the rotating frame 14 to rotate, so that the side of the rotating frame 14 away from the mating rod 16 moves upward. The rotating frame 14 can then push the push rod 13, so that the push rod 13 can push the connecting plate 11 to move upward. This allows the connecting plate 11 to drive the two insert plates 10 to move upward and stretch the two springs 12. The two insert plates 10 can then detach from the handle frame 9 and move to the top front position of the cover plate. At this time, the sealing plate 7 can be tilted through the handle frame 9. First, the bottom of the sealing plate 7 can be removed, and then the entire sealing plate 7 can be pulled out, bringing out the activated carbon plate 8. This allows the activated carbon plate 8 to be disassembled and replaced.

[0045] As a preferred embodiment of this utility model, symmetrically arranged springs 12 are fixedly installed on the top of the connecting plate 11. Both springs 12 are fixedly installed on the top of the outer shell 3. The springs 12 are used to reset the connecting plate 11 and the two insertion plates 10, so that the insertion plates 10 can automatically install the sealing plate 7.

[0046] As a preferred embodiment of this utility model, vertical sliding grooves are provided on the rear sides of both insertion plates 10, and symmetrically arranged sliding blocks are fixedly installed on the front side of the outer shell 3. The sliding blocks are slidably connected to the inner wall of the vertical sliding grooves. The sliding blocks and vertical sliding grooves are used for the insertion plates 10 to slide vertically on the front side of the outer shell 3, and can accurately engage with the handle bracket 9.

[0047] As a preferred embodiment of this utility model, a rectangular groove is provided on the top of the handle frame 9, and the bottom of the two insertion plates 10 slides in contact with the inner wall of the rectangular groove. The rectangular groove is used for the insertion of the insertion plates 10, so that the insertion plates 10 can enter the inner side of the handle frame 9 to install the sealing plate 7.

[0048] It should be noted that the specific model of the negative pressure-free water pump 5 to be used should be selected by those skilled in the art, and the above-mentioned negative pressure-free water pump 5 and the like are all existing technologies, which will not be elaborated on in this solution.

[0049] The working principle of this utility model is as follows: When water supply equipment is needed, water from the municipal pipeline is first pumped into the water tank 1 through the inlet pipe 2, and then pumped out by the negative pressure pump 5 and discharged through the outlet pipe 6. After entering the water tank 1, the water first passes through the outer shell 3 and is filtered by the activated carbon plate 8 inside the outer shell 3, preventing impurities from accumulating inside the water tank 1 or the outlet pipe 6. After the activated carbon plate 8 has been used for a long time, the pusher 15 can be pressed on the top of the outer shell 3. After the pusher 15 is pressed, it can press the rotating frame 14 to rotate, causing the side of the rotating frame 14 away from the mating rod 16 to move upward. The rotating frame 14 can then push the push rod 13, which in turn pushes the connecting plate 11 to move upward, allowing the connecting plate 11 to drive the two inserts. Plate 10 moves upward and stretches the two springs 12, allowing the two insert plates 10 to detach from the handle bracket 9 and move to the top front position of the cover plate. At this point, the sealing plate 7 can be tilted using the handle bracket 9. First, remove the bottom of the sealing plate 7, then pull out the entire sealing plate 7 and bring out the activated carbon plate 8, thus disassembling the activated carbon plate 8 and replacing it. Then, insert the new activated carbon plate 8 into the inside of the outer shell 3 and release the insert plate 10, allowing the insert plate 10 to enter the inside of the handle bracket 9. After the insert plate 10 is inserted into the inside of the handle bracket 9, it can prevent the sealing plate 7 from detaching from the outer shell 3. Furthermore, the insert plate 10 can also prevent the sealing plate 7 from tilting inside the outer shell 3 through the handle bracket 9, thus stably sealing the outer shell 3.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
