Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to a water purifier water supply device. Background Technology

[0002] In order to ensure the normal operation of the water purifier, in the absence of water supply conditions, it is necessary to use the water supply device of the water purifier to draw water from the water source and supply it to the water purifier.

[0003] The water supply device for water purifiers in related technologies uses a water pump to draw water and uses pipelines to transport the water from the water source to the water inlet of the water purifier. However, the water supply device for water purifiers in related technologies will work continuously when the power is on. When the water purifier does not need to supply water, the water pump motor will stall. In addition, it will generate a lot of noise and vibration during use, resulting in poor water supply reliability. Utility Model Content

[0035] The following is in conjunction with the appendix Figure 1-5 The embodiments of this application will be described in further detail.

[0036] Figure 1 A schematic diagram showing the connection relationship of a water purifier supply device in one embodiment of this application is shown; Figure 2 A schematic diagram of the water supply device for a water purifier according to one embodiment of this application is shown.

[0037] See Figure 1 and Figure 2An embodiment of this application provides a water purifier water supply device, including: a water pump 1 and a high-pressure switch 2; the pump body inlet 11 of the water pump 1 is connected to a water source 5 through an inlet pipe 3; the first end of the high-pressure switch 2 is connected to the pump body outlet of the water pump 1 through a first outlet pipe 41, the second end of the high-pressure switch 2 is connected to the water purifier through a second outlet pipe 42, and the third end of the high-pressure switch 2 is connected to an external power supply and the motor 12 of the water pump 1; wherein, the inlet pipe 3 is disposed on the first side of the water pump 1, and the first outlet pipe 41 and the second outlet pipe 42 are disposed on the second side of the water pump 1 opposite to the first side.

[0038] The water pump 1 has a cylindrical body and mainly includes a motor 12 and a pump head 13. The pump body inlet 11 and the pump body outlet of the water pump 1 are both located in the pump head 13. In one possible embodiment, the water pump 1 in the water purifier supply device is a self-priming booster water pump 1.

[0039] In one possible implementation, the high-pressure switch 2 in the water purifier supply device includes a reed for switching between a closed state and an open state based on the pressure in the first water outlet pipe 41 and the second water outlet pipe 42.

[0040] The reed in the high-pressure switch 2 can be made of elastic metal. When the pressure in the first outlet pipe 41 and the second outlet pipe 42 changes, the reed will bend or deform according to the force applied, thus switching between a closed state and an open state. When the reed is in the closed state, it contacts the electrical contacts in the high-pressure switch 2, and the high-pressure switch 2 connects the external power supply and the motor 12 of the water pump 1. When the reed is in the open state, it separates from the electrical contacts in the high-pressure switch 2, and the high-pressure switch 2 disconnects the electrical connection between the external power supply and the motor 12, thus de-energizing the motor 12. By placing the high-pressure switch 2 between the first outlet pipe 41 and the second outlet pipe 42, the pressure at the pump outlet and the pressure at the water purifier inlet can be accurately compared, thereby responding promptly to changes in the water purifier's status.

[0041] In one possible implementation, the water purifier supply device further includes: a one-way valve 7, the first end of which is connected to the first outlet pipe 41, and the second end of which is connected to the first end of the high-pressure switch 2.

[0042] The one-way valve 7 uses a disc-type, ball-type, or cone-type valve core to block reverse water flow, preventing supplied water from flowing back to the water source 5. When the water purifier does not need water supply, it maintains a high-pressure state in the second outlet pipe 42, keeping the motor 12 in a de-energized and non-operating state. In this way, through the cooperation of the one-way valve 7 and the high-pressure switch 2, the working state of the water pump 1 can be flexibly adjusted according to the water supply needs of the water purifier, avoiding the motor 12 from stalling and protecting the pipes and mechanisms in the water purifier's water supply device.

[0043] In one possible implementation, the water inlet pipe 3 includes: a first water inlet pipe 31 and a second water inlet pipe 32; the water purifier supply device also includes: a pre-filter mechanism 6, the first end of the pre-filter mechanism 6 is connected to the water source 5 through the first water inlet pipe 31, and the second end of the pre-filter mechanism 6 is connected to the pump body inlet 11 of the water pump 1 through the second water inlet pipe 32.

[0044] The pre-filter mechanism 6 contains a filter screen with a pore size of at least 50 mesh, capable of filtering particulate impurities from the incoming water source 5, preventing these impurities from entering the water pump 1 and causing wear and blockage to the impeller, seals, etc. Optionally, the pre-filter mechanism 6 can be detachably connected to the first inlet pipe 31 and the second inlet pipe 32. After a period of use, the pre-filter mechanism 6 can be disassembled to facilitate flushing of the filter screen, keeping it clean and maintaining a stable incoming water flow.

[0045] During the water supply process of the water purifier, the water inlet of the water purifier is opened. The pressure in the second water outlet pipe 42 connected to the water purifier is less than the pressure in the first water outlet pipe 41 connected to the pump body outlet. When the high pressure switch 2 detects that the water purifier side is under low pressure, the reed enters the closed state, the motor 12 of the water pump 1 is powered on, and the water flows from the water source 5 through the first water inlet pipe 31 into the pre-filter mechanism 6. After being filtered by the pre-filter mechanism 6, the water flows through the second water inlet pipe 32 and enters the water pump 1 from the pump body inlet 11. After being pressurized by the water pump 1, the water flows from the pump body outlet into the first water outlet pipe 41. After passing through the one-way valve 7 and the high pressure switch 2, the water flows into the water purifier from the second water outlet pipe 42, thus supplying water to the water purifier.

[0046] When the water purifier does not need to supply water, the water purifier's clean water outlet is closed. The pressure in the second water outlet pipe 42 connected to the water purifier is greater than the pressure in the first water outlet pipe 41 connected to the pump body outlet. When the high-pressure switch 2 detects that the water purifier is under high pressure, the reed enters the open state, the motor 12 of the water pump 1 is de-energized, and the water pump 1 stops drawing water from the water source 5 and supplying water to the water purifier.

[0047] The water purifier supply device provided in the above embodiments responds promptly to the water supply needs of the water purifier using a high-pressure switch 2, preventing motor blockage. The water pump 1 is positioned in the middle of the supply device, with the inlet pipe 3 on the first side of the pump 1, and the first outlet pipe 41 and the second outlet pipe 42 on the second side of the pump 1 opposite to the first side. This allows water drawn from the water source 5 to enter the pump 1 from one side, be pressurized by the pump 1, and then exit from the other side, avoiding fluid turbulence and reducing pressure loss. It also prevents noise caused by vibration and collision between the inlet pipe, the first outlet pipe 41, and the second outlet pipe 42 during water supply, making the water supply process to the water purifier more stable and efficient. Furthermore, it makes the overall structure of the water purifier supply device more compact, facilitating connection to external pipes, reducing pipe bend length, lowering installation and maintenance difficulty, and providing ample space for the high-pressure switch 2, thereby improving the reliability of water supply to the water purifier.

[0048] In one exemplary embodiment, see further... Figure 2 The water purifier's water supply device also includes: a housing 8, the cavity inside the housing 8 is used to house the water pump 1, the high-pressure switch 2 and the pre-filter mechanism 6, and the inner side of the housing 8 is covered with a sound insulation layer.

[0049] Among them, Figure 2 From this perspective, the sound insulation layer can cover the top and bottom of the inner side of the outer casing 8. The sound insulation layer is composed of materials with good sound absorption, damping properties, and durability. For example, the material of the sound insulation layer can be polyurethane foam, fiberglass wool, rock wool, rubber-based sound insulation felt, or polyester fiber wool. To ensure that the sound insulation layer can be firmly attached to the inner side of the outer casing 8, while ensuring heat dissipation and sound insulation effects, high-temperature resistant and environmentally friendly industrial adhesives, such as silicone or hot melt adhesives, can be used to fix the sound insulation layer to the inner wall of the outer casing 8. Optionally, slots or brackets can be designed on the inner wall of the outer casing 8 to embed or clamp the sound insulation layer inside the outer casing 8.

[0050] In one possible implementation, the water purifier supply device further includes: a housing inlet 81 and a housing outlet 82, which are connected to the housing 8 via a shock-absorbing pad 83.

[0051] The housing inlet 81 has one side connected to the water source 5 and the other side connected to the first inlet pipe 31; the housing outlet 82 has one side connected to the water purifier inlet and the other side connected to the second outlet pipe 42. The shock-absorbing pad 83 can be formed by combining an upper pad and a lower pad; the outer shell 8 is formed by combining an upper shell and a lower shell. Figure 2From the perspective of the upper and lower shells, the bottom of the lower pad is engaged with the lower shell, and the top of the lower pad is in contact with the shell inlet 81, the shell outlet 82 and the upper pad. In this way, under the clamping of the upper and lower shells, the upper and lower pads work together to clamp the shell inlet 81 and the shell outlet 82, absorbing the vibrations that occur at the shell inlet 81 and the shell outlet 82, thereby playing a shock absorption role.

[0052] Optionally, the housing inlet 81 is connected to the water source 5 via an external inlet pipe; the housing outlet 82 is connected to the water purifier inlet via an external outlet pipe. Both the external inlet and outlet pipes are adjustable-length water supply lines. This allows the water purifier's water supply device to be installed independently of the water purifier, adapting to different water supply environments. This effectively improves the applicability, flexibility, and operational stability of both the water purifier and its water supply device, while reducing production costs and maintenance complexity.

[0053] Optionally, the water supply device can also be integrated into the water purifier.

[0054] Figure 3 A schematic diagram of the connection structure of the shock absorber bracket in one embodiment of this application is shown; Figure 4 A schematic cross-sectional view of a shock-absorbing bracket according to one embodiment of this application is shown. (See also...) Figure 3 and Figure 4 In one possible implementation, the water purifier supply device further includes: a pump bracket 91, which is connected to the water pump 1; and a base bracket 92, which is connected to the pump bracket 91 via an elastic connector 93.

[0055] The pump bracket 91 includes a support part 911 and a connecting part 912. The support part 911 is used to support the motor 12 part of the water pump 1. The shape of the support part 911 can be consistent with the curvature of the outer surface of the motor 12 of the water pump 1 so as to fit closely and support the water pump 1. The connecting part 912 of the pump bracket 91 is provided with a mounting hole for the elastic connector 93 to pass through the connecting part 912 and connect to the base bracket 92.

[0056] The base bracket 92 is fixedly connected to the outer shell 8.

[0057] The elastic connector 93 includes a stepped screw 931, an elastic washer 932, and a nut 933. The elastic washer 932 and the nut 933 are respectively disposed on both sides of the base bracket 92. The stepped screw 931 is divided into two sections. The thicker stepped part is inserted into the elastic washer 932, and the thinner threaded part is used to pass through the mounting hole on the pump foot bracket 91 and is locked to the base bracket 92 by the nut 933. This increases the contact area between the elastic washer 932 and the base bracket 92, stably connecting the pump foot bracket 91 to the base bracket 92. The elastic washer 932 effectively buffers the vibration and impact generated during the operation of the water pump 1, ensuring the stability of the connection between the water pump 1, the pump foot bracket 91, and the base bracket 92.

[0058] In one possible implementation, the lengths of the first water inlet pipe 31, the second water inlet pipe 32, the first water outlet pipe 41, and the second water outlet pipe 42 are adjustable, the high-pressure switch 2 is adjustablely positioned on the first side of the water pump 1, and the pre-filter mechanism 6 is adjustablely positioned on the second side of the water pump 1.

[0059] Preferably, in one possible implementation, there are at least two sets of elastic connectors 93. The first set of elastic connectors 93 is disposed on both sides of the bottom of the pre-filter mechanism 6, and the second set of elastic connectors 93 is disposed on both sides of the bottom of the high-pressure switch 2. In this way, the pre-filter mechanism 6 and the high-pressure switch 2 are each located between a set of elastic connectors 93, which enables the pre-filter mechanism 6 and the high-pressure switch 2 to maintain a more stable state during operation, reduces vibration and stress, prevents components from loosening or shifting, and makes better use of limited space, making the overall structure more compact and reducing the volume of the water purifier's water supply device.

[0060] Figure 5 A schematic diagram of the bottom structure of a water purifier supply device provided in one embodiment of this application is shown. (See also...) Figure 5 In one exemplary embodiment, a rubber pad 84 is provided on the bottom of the housing 8. The rubber pads 84 on the bottom of the housing 8 are respectively disposed on opposite edges of the housing 8. Optionally, two rubber pads 84 are provided on each edge.

[0061] In one possible implementation, the first inlet pipe 31, the second inlet pipe 32, the first outlet pipe 41, and the second outlet pipe 42 in the provided water purifier supply device are covered with foam. The foam is a porous material based on polymer materials and made through a foaming process, which has the characteristics of being soft, lightweight, and elastic.

[0062] In one possible implementation, the pipes through the housing inlet 81 and housing outlet 82 are wrapped with rubber sleeves to further reduce pipe vibration and noise caused by the pipes colliding with the housing inlet 81 and housing outlet 82.

[0063] In the above embodiment, the water pump 1 is placed in the middle of the water purifier supply device, and two sets of elastic connectors 93 form a stable four-point support structure between the pump foot bracket 91 and the base bracket 92; the rubber pads 84 on both sides provide a four-point support structure for the outer shell 8, thereby effectively dispersing the weight of the water pump 1 and the vibration load generated during operation, avoiding the problem of excessive stress on one side, so that the water pump 1 can still maintain stable operation when the speed is high or the pressure changes, and preventing the water purifier supply device from shifting or tilting; the vibration generated during the operation of the water pump 1 is absorbed by the shock-absorbing pads 83 in the elastic connectors 93, the rubber pads 84 at the bottom of the outer shell 8, and the foam or rubber sleeve wrapped around the outside of the pipe, further reducing noise and improving the overall stability of the water purifier supply device.
