[0025] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In order to further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0027] The description in this section is only for several typical embodiments, and the present invention is not limited to the scope of the embodiments. The same or similar prior art means and some technical features in the embodiments are mutually replaced within the scope of the present invention.

[0028] The term “connection” in the specification includes both direct connection and indirect connection.

[0029] The present invention discloses a pressure boosting device for water supply equipment. Figure 1 This is a schematic diagram of the composition of a pressure boosting device for a water supply device according to an embodiment of the present invention; Figure 1 The pressurizing device includes: a container 1, a piston mechanism 2, a driving mechanism 3, a transmission mechanism 4, a plurality of valves 5, a first pipeline 6 and a second pipeline 7.

[0030] The piston mechanism 2 is arranged in the container 1, and can divide the container 1 into a first part 101 and a second part 102; the driving mechanism 3 is connected to the piston mechanism 2 through the transmission mechanism 4, and can drive the piston mechanism 2 to move in the container 1, thereby adjusting the size of the first part 101 and the second part 102.

[0031] The first pipeline 6 is provided with a water inlet 603, a first connecting port 601 and a second connecting port 602. The first pipeline 6 can receive water supply through the water inlet 603 (can be connected to a water supply pipeline), and the first pipeline 6 is connected to the container 1 through the first connecting port 601 and the second connecting port 602 respectively; the first connecting port 601 and the second connecting port 602 are respectively provided with a first valve 501 and a second valve 502.

[0032] The second pipeline 7 is provided with a water outlet 703, a third connection port 701 and a fourth connection port 702. The second pipeline 7 is connected to the container 1 through the third connection port 701 and the fourth connection port 702 respectively, and the second pipeline 7 can output water through the water outlet 703; the third connection port 701 and the fourth connection port 702 are provided with a third valve 503 and a fourth valve 504 respectively.

[0033] See also Figure 1 In one embodiment of the present invention, when the piston mechanism 2 is located at the set position, the first connection port 601 and the third connection port 701 are connected to the first part 101 of the container 1, and the second connection port 602 and the fourth connection port 702 are connected to the second part 102 of the container 1.

[0034] In one embodiment of the present invention, the piston mechanism 2 includes a piston body 201 and a piston sealing device 202; the piston sealing device 202 seals the piston body 201 axially. In one embodiment, the driving mechanism 3 may include a servo motor 301 and a reducer 302; the servo motor 301 is connected to the transmission mechanism 4 through the reducer 302. The transmission mechanism 4 may include a screw assembly; the screw assembly includes a screw 401, a screw nut 402, and upper and lower screw lubrication sleeves 403 and 404. The driving mechanism 3 is connected to the screw 401 and can drive the screw 401 to rotate; when the screw 401 rotates, the piston body 201 is driven to move; the first valve 501, the second valve 502, the third valve 503 and the fourth valve 504 may all be one-way check valves.

[0035] In one embodiment of the present invention, the inner circular wall of the container 1 is treated with a hydrophobic material to form a hygienic, wear-resistant, corrosion-resistant and smooth surface, which can achieve the following effects: first, the tap water is guaranteed to be hygienic in the tank body; second, the sealing ring on the piston body 201 and the inner circular wall of the container 1 are not easily worn when the piston body 201 moves up and down; third, tap water is prone to corrosion due to the residual chlorine contained in it, and since the inner circular wall of the container 1 has been treated with a hydrophobic material, no corrosion will occur; fourth, since the inner circular wall of the container 1 has been treated with a hydrophobic material, tap water will not remain on the inner circular wall of the container 1.

[0036] In addition, the piston body 201 can be made of light material and treated with hydrophobic material on the outer surface; the use of light material is conducive to reducing the power consumption of the servo motor 301; the hydrophobic treatment on the outer surface is conducive to corrosion resistance and no residue, ensuring hygiene. In one embodiment, the piston body 201 is sealed with the sealing ring between the container 1, and the sealing ring and the piston body 201 together separate the inner cavity of the container 1 into two spaces. When the piston body 201 moves upward, water flows out of the upper cavity and enters the lower cavity; when the piston body 201 moves downward, water flows in and out of the upper cavity and flows out of the lower cavity, forming a continuous water supply cycle.

[0037] In one embodiment of the present invention, the screw rod 401 is built into the container 1 to reduce the volume of the entire device. In addition, the screw rod 401 is driven to rotate by the servo motor 301 through the reducer 302. When the screw rod 401 rotates forwards and backwards, it drives the piston body 201 to move up and down; the piston body 201 is embedded with the screw rod nut 402 (which can be a screw rod lubrication nut), and the screw rod nut 402 drives the piston body 201 to move up and down when the screw rod 401 rotates forwards and backwards; the screw rod nut 402 is made of self-lubricating metal or non-metallic material to reduce the friction between the screw rod 401 and the screw rod nut 402.

[0038] like Figure 1 As shown, in one embodiment of the present invention, the booster device further comprises a guide mechanism 8, and the piston mechanism 2 moves under the guidance of the guide mechanism 8. In one embodiment, the guide mechanism 8 comprises at least one guide rod 801, and the piston mechanism 2 passes through the guide rod 801 and can move under the guidance of the guide rod 801. The guide rod 801 is provided with a guide rod lubricating sleeve.

[0039] In one embodiment of the present invention, the guide rod 801 and the guide rod lubricating sleeve are built into the container 1, and both pass through the piston body 201. The guide rod lubricating sleeve is nested in the guide rod inner hole of the piston body 201. The guide rod 801 cooperates with the guide rod lubricating sleeve. When the piston body 201 moves up and down, the guide rod 801 and the guide rod lubricating sleeve prevent the piston body 201 from rotating. The guide rod lubricating sleeve is made of self-lubricating metal or non-metallic material to reduce friction with the piston body 201.

[0040] In one embodiment of the present invention, the boosting device uses the servo motor 301 as a power source, which is decelerated by the reducer 302 to drive the screw rod 401 to rotate forward and reverse, and then drives the piston body 201 to move up and down.

[0041] Please continue reading Figure 1In one usage scenario of the present invention, after being decelerated by the reducer 302, the servo motor 301 drives the screw rod 401 to rotate, so that the piston body 201 moves up and down. When the piston body 201 moves downward, the third valve 701 is closed, the first valve 601 is opened, and water is introduced into the container 1 (the container can be a tank body) from the water inlet 603, the second valve 602 is closed, and the fourth valve 702 is opened to supply water to the water outlet 703; when the piston body 201 reaches the bottom, it will immediately move upward, the fourth valve 702 is closed, the second valve 602 is opened, water is introduced into the container 1 from the water inlet 603, the first valve 601 is closed, and the third valve 701 is opened to supply water to the water outlet 703.

[0042] The present invention also discloses a water supply device, comprising the above-mentioned pressure boosting device. In one embodiment, the water supply device is a secondary water supply device.

[0043] In another embodiment of the present invention, the water supply equipment boosting devices can be used in combination of multiple units to increase the water supply capacity.

[0044] In yet another embodiment of the present invention, the water supply equipment booster device may be installed horizontally.

[0045] In summary, the water supply equipment and the booster device thereof proposed in the present invention can adjust a large flow range, have a stable delivery pressure, consume little power, have an obvious energy-saving effect, and can well meet various water requirements of residential users.
