The present invention discloses a circulating water machine and a circulation system, wherein a water inlet is connected to a water outlet of an external water source, and water from the external water source can flow into a circulation box, and then flow out of the circulation box through a first water outlet for use by users. Since the water inlet and the first blade of a rotating impeller are arranged relative to each other, the water flow flowing in from the water inlet will act on the first blade and drive the rotating impeller to rotate in the circulation box. Since the rotating impeller is matched with the driving impeller through a transmission member, the rotating impeller will drive the driving impeller to rotate, and the rotating driving impeller provides extraction power to the water pump structure, so that the water to be recycled is input from the water pumping port and output from the second water outlet, thereby completing the collection of the water to be recycled to realize the recycling of domestic water. In this way, not only the electric energy resources are greatly saved, and the recycling process is green and environmentally friendly, but also the extraction process of the water to be recycled is made safer.

Description

Technical Field

[0001] The present invention relates to the technical field of water resource recycling, and in particular to a circulating water machine and a circulating system. Background Art

[0002] Water, as an important component of natural resources, is the main material basis for the structure and life activities of all organisms, and maintains the normal operation of all ecosystems. However, with the excessive exploitation and irrational use of humans, water resources have gradually become scarce resources, and more and more regions have gradually experienced moderate or severe water shortages. Therefore, the issue of how to effectively recycle and utilize water resources has become imminent.

[0003] In daily life, a lot of water is needed in many places, such as flushing toilets, washing clothes, taking a bath, etc. Among them, the water consumed by taking a bath accounts for the vast majority of daily water consumption. However, the water after taking a bath is usually discharged directly through the sewer pipe, resulting in a large amount of water being wasted.

[0004] To this end, some people use electric pumps to pump back the domestic water and reuse the recycled water. However, electric pumps are live during use, which can easily cause safety accidents such as electric leakage and injury. At the same time, a large amount of electricity is consumed in the process of recycling domestic water, which increases the cost of water resource recycling. Summary of the invention

[0005] Based on this, it is necessary to provide an energy-saving, safe and green environmentally friendly circulating water machine and circulating system.

[0006] The technical solution is as follows:

[0007] A circulating water machine comprises: a circulation box body, the circulation box body is provided with a water inlet, a first water outlet and a through hole, the water inlet is used to communicate with the water outlet end of an external water source; a rotating impeller, the rotating impeller is rotatably arranged in the circulation box body, the first blade of the rotating impeller is arranged opposite to the water inlet, the water inlet is used to input water to drive the rotating impeller to rotate; and a water pump structure and a transmission member, the water pump structure is provided with a water suction port and a second water outlet, the water pump structure comprises a driving impeller, the transmission member penetrates into the through hole, and the rotating impeller is matched with the driving impeller through the transmission member, and the driving impeller is rotated to input water to be recovered from the water suction port and output it from the second water outlet.

[0008] The above-mentioned circulating water machine connects the water inlet with the water outlet of the external water source, and the water from the external water source can flow into the circulation box, and then flow out of the circulation box through the first water outlet for use by the user. Since the water inlet and the first blade of the rotating impeller are arranged relative to each other, the water flow flowing in from the water inlet will act on the first blade and drive the rotating impeller to rotate in the circulation box. Since the rotating impeller is matched with the driving impeller through the transmission member, the rotating impeller will drive the driving impeller to rotate, and the rotating driving impeller provides extraction power to the water pump structure, so that the water to be recycled is input from the water pumping port and output from the second water outlet, thereby completing the collection of the water to be recycled, and the collected water can be used again to realize the recycling of domestic water. Since this solution utilizes the flow of water in the circulation box to generate flow force, drives the rotating impeller to rotate, and converts the flow force into driving force for driving the impeller, so that the water pump structure can work continuously and stably. Therefore, during the recycling process, it completely relies on the flow force of water as the power source, and no additional electricity is required from the outside. This not only greatly saves electricity resources and realizes the green and environmentally friendly recycling process, but also makes the extraction process of recycled water safer.

[0009] The principle and effect of the present invention are further described below in combination with the above scheme:

The shell is arranged on the circulation box, the driving impeller and the second surrounding edge are located in the shell, and the second surrounding edge is arranged on the driving impeller. The water suction port and the second water outlet are both arranged on the shell, the water suction pipe passes through the water suction port to be connected with the second surrounding edge, the second water outlet pipe passes through the second water outlet to be connected with the second surrounding edge, and the driving impeller rotates in the second surrounding edge to pump the water to be recovered from the water suction pipe to the second water outlet pipe.

Since the water inlet and the first blade of the rotating impeller are arranged relative to each other, the water flow flowing in from the water inlet will act on the first blade and drive the rotating impeller to rotate in the circulation box. Since the rotating impeller is transmitted and matched with the driving impeller through the transmission member, the rotating impeller will drive the driving impeller to rotate, and the rotating driving impeller provides extraction power to the water pump structure, so that the water to be recycled is input from the water pumping port and output from the second water outlet, thereby completing the collection of the water to be recycled, and the collected water can be used again to realize the recycling of domestic water. Since this solution utilizes the flow of water in the circulation box to generate flow force, drives the rotating impeller to rotate, and converts the flow force into driving force for driving the impeller, so that the water pump structure can work continuously and stably.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0033] In one embodiment, please refer to Figure 1 and Figure 2 A circulating water machine 100 includes: a circulation box 110, a rotating impeller 120, a water pump structure 170 and a transmission member 130. The circulation box 110 is provided with a water inlet 1111, a first water outlet 1112 and a through hole 1113. The water inlet 1111 is used to communicate with the water outlet end of an external water source. The rotating impeller 120 is rotatably arranged in the circulation box 110, and the first blade 121 of the rotating impeller 120 is arranged opposite to the water inlet 1111. The water inlet 1111 is used to drive the rotating impeller 120 to rotate by the input water. The water pump structure 170 is provided with a water suction port 17211 and a second water outlet 17212, and the water pump structure 170 includes a driving impeller 171. The transmission member 130 penetrates into the through hole 1113, and the rotating impeller 120 is driven and matched with the driving impeller 171 through the transmission member 130. The driving impeller 171 is rotated to input the water to be recycled from the water pumping port 17211 and output the water from the second water outlet 17212 .

[0034] The above-mentioned water circulation machine 100 connects the water inlet 1111 with the water outlet of the external water source, and the water from the external water source can flow into the circulation box 110, and then flow out of the circulation box 110 through the first water outlet 1112 for use by the user. Since the water inlet 1111 is arranged opposite to the first blade 121 of the rotating impeller 120, the water flowing in from the water inlet 1111 will act on the first blade 121 and drive the rotating impeller 120 to rotate in the circulation box 110. Since the rotating impeller 120 is in transmission cooperation with the driving impeller 171 through the transmission member 130, the rotating impeller 120 will drive the driving impeller 171 to rotate, and the rotating driving impeller 171 provides extraction power to the water pump structure 170, so that the water to be recycled is input from the water pumping port 17211 and output from the second water outlet 17212, thereby completing the collection of the water to be recycled, and the collected water can be used again to achieve the recycling of domestic water. Since the present embodiment uses the flow of water to generate flow force in the circulation box 110, drives the rotating impeller 120 to rotate, and converts the flow force into the driving force of the driving impeller 171, so that the water pump structure 170 works continuously and stably, therefore, in the recycling process, it completely relies on the flow force of water as a power source, and no additional electric energy is required from the outside, so that not only the electric energy resources are greatly saved, and the recycling process is green and environmentally friendly, but also the extraction process of the water to be recycled is safer. At the same time, the circulating water machine 100 of this embodiment has a simple structure, occupies a small space, is easy to operate, etc., which greatly improves the user experience.

[0035] Optionally, there are multiple ways to realize the transmission cooperation between the rotating impeller 120 of this embodiment and the driving impeller 171 through the transmission member 130, and it is only necessary to satisfy that the rotating impeller 120 can drive the driving impeller 171 to rotate. For example: the rotating impeller 120 and the driving impeller 171 are coaxially connected through the transmission member 130; or, the rotating impeller 120, the transmission member 130 and the driving impeller 171 are connected by gear transmission; or, the rotating impeller 120 and the transmission member 130 are coaxially connected, and the transmission member 130 and the driving impeller 171 are connected by gear transmission; or, the rotating impeller 120 and the transmission member 130 are connected by gear transmission, and the transmission member 130 and the driving impeller 171 are coaxially connected.

[0036] Optionally, the present embodiment does not specifically limit the external water source, as long as it can satisfy the flow force generated by the water flow in the circulation box 110, wherein the external water source can be a tap water pipe or a bathing water pipe. When the external water source is a tap water pipe, the water to be recycled is the water discharged after the tap water is used; when the external water source is a bathing water pipe, the water to be recycled is the water generated during the bathing process. At the same time, the extracted water to be recycled can be collected and then used for irrigation or flushing toilets, etc.

[0037] It should be noted that the water pump structure 170 used in this embodiment is a small, simple device, and the flow force generated by the water flow is fully capable of driving the driving impeller 171 to rotate, so that the water pump structure 170 can work stably. Among them, the water pump structure 170 can be a centrifugal pump, an axial flow pump or a mixed flow pump.

[0038] It should also be noted that the relative arrangement of the first blade 121 of the rotating impeller 120 and the water inlet 1111 should be understood as: the opening end of the water inlet 1111 is arranged toward the first blade 121, that is, the water flow input from the water inlet 1111 can impact the first blade 121, so that the rotating impeller 120 rotates in the circulation box 110.

[0039] For further information, please refer to Figure 2 The circulating water machine 100 further includes a water inlet pipe 160, a first water outlet pipe 161 and a first enclosure 140. The first enclosure 140 is arranged around the rotating impeller 120. The water inlet pipe 160 is connected to the first enclosure 140 through the water inlet 1111. The first water outlet pipe 161 is connected to the first enclosure 140 through the first water outlet 1112. In this embodiment, the first enclosure 140 is arranged around the rotating impeller 120 to reduce the space where the rotating impeller 120 is located, so that the water flow velocity flowing out of the water inlet pipe 160 is increased, and the flow force generated by the water flow is sufficient to drive the rotating impeller 120 to rotate, so that the circulating water machine 100 can work continuously and stably.

[0040] Specifically, please refer to Figure 2 and Figure 3 The first enclosure 140 is connected to the bottom of the circulation box 110, and a sealing ring 1122 is provided at the top of the circulation box 110. One end of the sealing ring 1122 is sealed with one end of the first enclosure 140. In this way, the rotating impeller 120 is in a sealed environment in the first enclosure 140, ensuring that most of the water flow input from the water inlet pipe 160 acts on the rotating impeller 120, thereby making the rotation torque of the rotating impeller 120 larger. At the same time, the sealing ring 1122 is sealed with the first enclosure 140, so that the water flowing into the first enclosure 140 is effectively pressurized, avoiding reducing the water flow speed flowing out of the first outlet pipe 161 and affecting the user's use.

[0041] For further information, please refer to Figure 2 The water inlet pipe 160 and the first water outlet pipe 161 are arranged vertically or substantially vertically, so as to ensure that the impact force of the water flow is maximized on the rotating impeller 120 before flowing out of the first water outlet pipe 161. Wherein, the substantially vertical arrangement should be understood that the angle between the water inlet pipe 160 and the first water outlet pipe 161 can float up and down 90 degrees, and the specific deviation value of the angle can be determined according to the actual product.

[0042] In one embodiment, please refer to Figure 2 , one end of the transmission member 130 is connected to the rotating impeller 120. The other end of the transmission member 130 is connected to the driving impeller 171. It can be seen that the transmission cooperation mode of the rotating impeller 120 and the driving impeller 171 in this embodiment is to realize synchronous rotation directly through the transmission member 130. Specifically in this embodiment, one end of the transmission member 130 is coaxially connected to the rotating impeller 120, and the other end of the transmission member 130 is coaxially connected to the driving impeller 171.

[0043] Optionally, the connection method between one end of the transmission member 130 and the rotating impeller 120 can be a key shaft connection, bolt connection, screw connection, welding, clamping or other connection methods; similarly, the connection method between the other end of the transmission member 130 and the driving impeller 171 can also be a key shaft connection, bolt connection, screw connection, welding, clamping or other connection methods.

[0044] For further information, please refer to Figure 5 and Figure 6 , a first axial hole 123 is provided on the rotating impeller 120. A first limiting portion 124 is provided on the hole wall of the first axial hole 123. A second limiting portion 131 is provided on the transmission member 130. When the transmission member 130 is inserted into the first axial hole 123, the first limiting portion 124 and the second limiting portion 131 are limited and matched. In this way, the transmission member 130 is tightly connected to the rotating impeller 120 through the cooperation of the first limiting portion 124 and the second limiting portion 131, ensuring that the transmission member 130 and the rotating impeller 120 rotate synchronously. At the same time, through the cooperation of the first limiting portion 124 and the second limiting portion 131, the connection between the rotating member and the rotating impeller 120 is more convenient, which is conducive to improving the assembly efficiency of the circulating water machine 100.

[0045] Optionally, the first limiting portion 124 is a limiting strip, and the second limiting portion 131 is a limiting groove; or, the first limiting portion 124 is a limiting groove, and the second limiting portion 131 is a limiting strip.

[0046] For further information, please refer to Figure 5 and Figure 6 , a first interference portion 134 is provided on the transmission member 130. A second interference portion 125 that interferes with the first interference portion 134 is provided on the rotating impeller 120. In this way, the rotating impeller 120 is stably supported on the transmission member 130 through the cooperation between the first interference portion 134 and the second interference portion 125. Specifically in the present embodiment, the first interference portion 134 is a cylindrical structure, and the second interference portion 125 is a disc structure. At the same time, the diameter of the disc structure is equal to the diameter of the through-hole 1113 or the diameter of the disc structure is slightly smaller than the diameter of the through-hole 1113, so that the disc structure fits better in the through-hole 1113, which can effectively prevent water from leaking from the gap between the disc structure and the through-hole 1113; and ensure that the disc structure rotates stably in the through-hole 1113.

[0047] In one embodiment, please refer to Figure 6 and Figure 7 , a second axial hole 1712 is provided on the driving impeller 171. A third limiting portion 1713 is provided on the hole wall of the second axial hole 1712. A fourth limiting portion 132 is provided on the transmission member 130. When the transmission member 130 is inserted into the second axial hole 1712, the third limiting portion 1713 and the fourth limiting portion 132 are limited and matched. Similarly, through the cooperation of the third limiting portion 1713 and the fourth limiting portion 132, the transmission member 130 is tightly connected with the driving impeller 171, ensuring that the transmission member 130 and the driving impeller 171 rotate synchronously. At the same time, through the cooperation of the third limiting portion 1713 and the fourth limiting portion 132, the connection between the rotating member and the driving impeller 171 is more convenient, which is conducive to improving the assembly efficiency of the circulating water machine 100.

[0048] Optionally, the third limiting portion 1713 is a limiting strip, and the fourth limiting portion 132 is a limiting groove; or, the third limiting portion 1713 is a limiting groove, and the fourth limiting portion 132 is a limiting strip.

[0049] For further information, please refer to Figure 6 and Figure 7 , the driving impeller 171 is provided with a third conflicting portion 1714 that conflicts with the first conflicting portion 134. In this way, the driving impeller 171 is stably supported on the transmission member 130 through the cooperation between the first conflicting portion 134 and the third conflicting portion 1714. Specifically in this embodiment, the first conflicting portion 134 is a cylindrical structure, and the third conflicting portion 1714 is a disc structure. At the same time, the diameter of the disc structure is equal to the diameter of the through hole 1113 or the diameter of the disc structure is slightly smaller than the diameter of the through hole 1113, so that the disc structure fits better in the through hole 1113.

[0050] In one embodiment, please refer to Figure 2 The circulating water machine 100 further includes a support shaft 150. A rotating shaft hole 133 is provided on the transmission member 130. The support shaft 150 is disposed in the circulating water tank. The transmission member 130 is sleeved on the support shaft 150 through the rotating shaft hole 133. In this way, the transmission member 130 rotates more stably on the circulating box body 110 through the support shaft 150, so that the driving impeller 171 can extract the water to be recycled more stably.

[0051] For further information, please refer to Figure 2 and Figure 3, a first fixing portion 1123 is provided at the bottom of the circulation box 110, and one end of the support shaft 150 is arranged on the first fixing portion 1123, so that the support shaft 150 is stably supported in the circulation box 110 through the first fixing portion 1123, ensuring that the rotation of the transmission member 130 is more stable. Specifically in this embodiment, a socket is provided on the first fixing portion 1123, and the support shaft 150 is inserted into the socket. Among them, the first fixing portion 1123 of this embodiment is a cylindrical structure.

[0052] In one embodiment, please refer to Figure 1 The circulation box 110 includes a circulation frame 111 and a second cover 112 detachably arranged on the circulation frame 111. It can be seen that when the impeller 120 fails, the impeller 120 can be maintained or replaced by simply removing the second cover 112 from the circulation frame 111, which greatly improves the maintenance efficiency of the circulating water machine 100.

[0053] For further information, please refer to Figure 1 and Figure 3 The circulation frame 111 is provided with a first buckle portion 1114, and the second cover 112 is provided with a second buckle portion 1121 buckled with the first buckle portion 1114. In this way, the second cover 112 is more conveniently connected to the circulation frame 111 by buckling.

[0054] Optionally, the first buckle portion 1114 is a hook structure, and the second buckle portion 1121 is a slot structure; or, the first buckle portion 1114 is a slot structure, and the second buckle portion 1121 is a hook structure.

[0055] In one embodiment, please refer to Figure 3 The first fixing portion 1123 and the sealing ring 1122 are both disposed on the second cover 112 , and the rotating impeller 120 , the first surrounding edge 140 and the through hole 1113 are all disposed in the circulation frame 111 .

[0056] In one embodiment, please refer to Figure 5 The rotating impeller 120 includes a rotating shaft 122 and first blades 121. There are multiple first blades 121, and the multiple first blades 121 are arranged at intervals along the circumference of the rotating shaft 122. In this way, the force of the water flow on the rotating impeller 120 is more uniform, so that the rotating impeller 120 can rotate continuously and stably. Specifically in this embodiment, there are six first blades 121, and the six first blades 121 are evenly spaced on the rotating shaft 122.

[0057] In one embodiment, please refer to Figure 2The water pump structure 170 further includes a housing 172, a water suction pipe 174, a second water outlet pipe 175 and a second surrounding edge 173. The housing 172 is disposed on the circulation box 110. The driving impeller 171 and the second surrounding edge 173 are located in the housing 172, and the second surrounding edge is disposed around the driving impeller 171. The water suction port 17211 and the second water outlet port 17212 are both disposed on the housing 172, the water suction pipe 174 passes through the water suction port 17211 to communicate with the second surrounding edge 173, the second water outlet pipe 175 passes through the second water outlet port 17212 to communicate with the second surrounding edge 173, and the driving impeller 171 rotates in the second surrounding edge 173 to pump the water to be recovered from the water suction pipe 174 to the second water outlet pipe 175. It can be seen that when the driving impeller 171 rotates driven by the rotating impeller 120, the driving impeller 171 forms an extraction force in the second surrounding edge 173, so that the water to be recycled is input from the pumping pipe 174 and output from the second water outlet pipe 175, thereby completing the recovery operation of the water to be recycled.

[0058] It should be noted that the water pump structure 170 of this embodiment can be designed according to the principles of a centrifugal pump, an axial flow pump or a mixed flow pump. For example, when the water pump structure 170 is a centrifugal pump, the second blade 1711 on the driving impeller 171 will form a certain negative pressure on the side wall of the second surrounding edge 173, and a pumping pipe 174 is correspondingly provided at the negative pressure generating location. Of course, as to how the driving impeller 171 specifically generates the extraction power in the second surrounding edge 173, it is a prior art and is not a technical solution protected by this embodiment, and therefore, it will not be described in detail here.

[0059] For further information, please refer to Figure 4 The housing 172 includes a water pump frame 1721 and a first cover 1722 detachably disposed on the water pump frame 1721, and the water pump frame 1721 is disposed on the circulation box 110. It can be seen that when the driving impeller 171 fails, the driving impeller 171 can be maintained or replaced by simply removing the first cover 1722 from the water pump frame 1721, which greatly improves the maintenance efficiency of the circulating water machine 100. Specifically in the present embodiment, the water pump frame 1721 is disposed on the circulation frame 111. Among them, the water pump frame 1721 can be disposed on the circulation frame 111 in a snap-fit ​​manner, a bolt connection manner, an integrated molding manner, and the like.

[0060] For further information, please refer to Figure 4The water pump frame 1721 is provided with a third buckle portion 17213, and the first cover 1722 is provided with a fourth buckle portion 17221 that buckles with the third buckle portion 17213. In this way, the first cover 1722 is more conveniently connected to the water pump frame 1721 by buckling. Specifically in this embodiment, the first cover 1722 is provided with a second fixing portion 17222, and one end of the support shaft 150 is disposed on the second fixing portion 17222.

[0061] Optionally, the third buckle portion 17213 is a hook structure, and the fourth buckle portion 17221 is a slot structure; or, the third buckle portion 17213 is a slot structure, and the fourth buckle portion 17221 is a hook structure.

[0062] In one embodiment, please refer to Figure 1 and Figure 2 A circulation system includes an external water source and a circulating water machine 100 in any one of the above embodiments, wherein the water outlet of the external water source is connected to the water inlet 1111.

[0063] The above-mentioned circulation system adopts the above-mentioned circulating water machine 100, connects the water inlet 1111 with the water outlet of the external water source, so that the water from the external water source can flow into the circulation box 110; and then flows out of the circulation box 110 through the first water outlet 1112 for use by the user. Since the water inlet 1111 and the first blade 121 of the rotating impeller 120 are arranged opposite to each other, the water flow flowing in from the water inlet 1111 will act on the first blade 121 and drive the rotating impeller 120 to rotate in the circulation box 110. Since the rotating impeller 120 is in transmission cooperation with the driving impeller 171 through the transmission member 130, the rotating impeller 120 will drive the driving impeller 171 to rotate, and the rotating driving impeller 171 provides extraction power to the water pump structure 170, so that the water to be recycled is input from the water pumping port 17211 and output from the second water outlet 17212, thereby completing the collection of the water to be recycled, and the collected water can be used again to achieve the recycling of domestic water. Since the present embodiment uses the flow of water to generate flow force in the circulation box 110, drives the rotating impeller 120 to rotate, and converts the flow force into the driving force of the driving impeller 171, so that the water pump structure 170 works continuously and stably, therefore, in the recycling process, it completely relies on the flow force of water as a power source, and no additional electric energy is required from the outside, so that not only the electric energy resources are greatly saved, and the recycling process is green and environmentally friendly, but also the extraction process of the water to be recycled is safer.

[0064] Specifically, the external water source is a bathing water pipe, and the water to be recycled is the water after bathing. In this way, when the bathing water pipe is connected to the water inlet 1111, the bathing water enters the circulation box 110 through the water inlet 1111, and forms a flow force in the circulation box 110 to drive the rotating impeller 120 to rotate. The bathing water entering the circulation box 110 is then output through the first water outlet 1112 to provide the user with bathing use; at the same time, the rotating impeller 120 will drive the driving impeller 171 to rotate, so that the driving impeller 171 generates extraction power, so that the water after bathing is extracted from the water pumping port 17211 and collected from the second water outlet 17212. The collected water after bathing can be used to flush toilets, water plants, etc.
