Description

Technical Field

[0001] This utility model relates to the field of shielded centrifugal booster pump technology, specifically to a shielded centrifugal booster pump built into a power adapter. Background Technology

[0002] A fluid pump is a device that transports fluids using the rotation of an electric motor. An automatic fluid pump is a fluid pump in which the fluid is automatically controlled. In daily life, when using water in situations such as high-rise buildings or bathrooms, we often encounter problems such as insufficient water pressure and low water flow, resulting in a poor user experience, and even problems such as the malfunction of related equipment in the pipeline. For example, when using a gas water heater, we may encounter situations where the water flow is too weak and ignition fails. In such cases, it is necessary to use an automatic booster pump to automatically pressurize the pipeline system.

[0003] For example, the Chinese utility model patent disclosed in patent application number CN201921842179.X (publication number CN211422878U) entitled "Tankless Intelligent Booster Pump" includes a housing assembly and a control panel. The housing assembly has an inner cavity, and the control panel is provided with a pressure adjustment switch for adjusting the pump start pressure value. The inner cavity of the housing assembly has a flow channel, and the housing assembly is provided with an inlet end and an outlet end. The inlet end is provided with a valve structure that can sense the fluid flow in the flow channel and control the start and stop of the pump motor. The housing assembly is provided with a fluid pressure detection sensor that senses the hydraulic pressure change in the flow channel, and the fluid pressure detection sensor has a control panel that controls whether the pump motor starts or not based on the sensing result of the hydraulic pressure change in the flow channel.

[0004] Both the control panel and the booster pump require wires for electrical connection. Current booster pumps usually also require an adapter, which is external. If the adapter is independent of the booster pump, the control panel and the booster pump are connected to the adapter via wires during use, and the adapter is connected to the mains power via wires. When not in use, the control panel is disconnected from the adapter, and the user needs to find a separate place to put the adapter. However, this makes it easy to forget where the adapter is placed, resulting in the adapter being lost.

[0005] Even though the adapter is connected to the pump body and does not need to be placed separately, the external adapter still makes the pump structure less compact. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a shielded centrifugal booster pump built into a power adapter to prevent adapter loss, based on the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a shielded centrifugal booster pump built into a power adapter, comprising...

[0008] shell;

[0009] The pump body is housed within the outer casing;

[0010] A control board, mounted on the pump body and located in the housing, is used to control whether the pump body is working;

[0011] Its characteristic is that it also includes

[0012] An adapter is installed in the housing and is located adjacent to the control board. The output of the adapter is electrically connected to the control board, and the input of the adapter is connected to a wire, one end of which passes through the housing for connection to the mains power.

[0013] Preferably, a positioning block is installed on the side wall of the housing, adjacent to the adapter, and the wire passes through the positioning block. This makes the wire more compact within the pump body, preventing the wire from being too long, tangling, or knotting within the pump body.

[0014] To facilitate operation of the control panel, the control panel is located near the top wall of the outer casing. The top wall of the outer casing has a perforated hole, and a pressing arm is installed in the perforated hole. One end of the pressing arm is connected to the wall of the perforated hole, and the other end can be deflected up and down. The control panel has a contact point facing the other end of the pressing arm.

[0015] Preferably, the pump body includes a pump casing and a pipe located beside the pump casing. The pump casing has an inlet, an outlet, and an impeller that draws water from the inlet to the outlet. The pipe is connected to the outlet of the pump casing, and a flow switch for controlling the flow at the outlet is provided in the pipe. The top wall of the pump casing is higher than the top wall of the pipe. The control board is located on the top of the pump casing, and a bracket is provided on the pipe. The adapter is mounted on the bracket. This design makes full use of the space in the pump body. The control board is plate-shaped, occupying little vertical space, so it is placed on the relatively tall pump casing. Placing the control board on the pump casing facilitates control of the motor inside the pump casing. Mounting the bracket on the pipe fully utilizes the space above the pipe, preventing the overall volume of the pump body from becoming too large.

[0016] To facilitate the relative fixation of the bracket and the tube, the top of the tube is provided with a vertically extending connecting column, and the bracket is provided with a connecting plate located at the top of the connecting column. The connecting plate and the connecting column are connected by a first connector.

[0017] Preferably, the connecting column has a limiting piece extending radially on its peripheral wall, and the bracket has a latch that can engage the limiting piece. The first connecting member extends vertically, and the latch extends horizontally. During installation, the latch engages the limiting piece to pre-position the bracket horizontally. Then, the connecting plate and the connecting column are vertically connected by the first connecting member. The latch and the first connecting member position the bracket in different directions, resulting in good positioning.

[0018] Preferably, the top of the tube is provided with a support platform, and the bracket is placed on the support platform, so that there is a gap between the bracket and the top wall of the tube to allow for heat dissipation.

[0019] In the above scheme, the water flow switch includes

[0020] The valve core can move along the pipe body axially to be in a first position or a second position. When the valve core is in the first position, the valve core opens the water outlet. When the valve core is in the second position, the valve core closes the water outlet.

[0021] The elastic element acts on the valve core, causing the valve core to always tend to move towards the second position;

[0022] A magnet is located inside the valve core;

[0023] A reed switch, located on the side wall of the tube, works in conjunction with a magnet to control whether the motor of a shielded centrifugal booster pump starts.

[0024] Preferably, the shielded centrifugal booster pump built into the power adapter also includes a housing box into which a reed switch can be detachably housed. The outer peripheral wall of the tube body has a horizontally extending groove. The housing box is partially detachably housed in the groove. A mounting plate is connected to the top or bottom of the housing box. The mounting plate and the tube body are detachably connected via a second connector. The second connector extends horizontally, and its extension direction is perpendicular to the extension direction of the groove. By installing the reed switch in the housing box, which is detachably mounted on the tube body, if the reed switch malfunctions, the housing box can be removed, the reed switch removed, a new reed switch replaced, and then reinstalled on the tube body, without rendering the entire shielded centrifugal booster pump unusable.

[0025] In addition, the tube body is provided with a groove, the extension direction of which is perpendicular to the extension direction of the second connector. The groove and the second connector position the accommodating box in different directions to ensure that the accommodating box is firmly assembled on the tube body. Since the accommodating box is partially detachably embedded in the groove, the mounting plate can be detachably installed on the tube body through the second connector, so that the accommodating box can be removed from the tube body.

[0026] To facilitate the installation of the receiving box onto the pipe body, the mounting plate is provided with a sleeve extending along the extension direction of the second connector. The outer wall of the pipe body is provided with a post that can be inserted into the sleeve. The sleeve and the post are detachably connected via the second connector. During installation, the receiving box is first partially embedded in the groove, and the post is inserted into the sleeve, thus pre-positioning the receiving box onto the pipe body. Then, the sleeve and the post are connected via the second connector, thus securely installing the receiving box onto the pipe body.

[0027] Compared with the prior art, the advantages of this utility model are: by fixing the adapter in the pump body, there is no need to find a separate place to put the adapter when it is not in use, which can prevent loss. In addition, the adapter is built into the pump body, making the overall structure of the water pump more compact. Attached Figure Description

[0037] In the description of this utility model patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0038] like Figures 1-7 As shown, the shielded centrifugal booster pump built into the power adapter in this preferred embodiment includes a housing 1, a pump body 2, a control board 3, and an adapter 4.

[0039] The pump body 2 is housed within the outer casing 1. The control board 3 is mounted on the pump body 2 and located within the outer casing 1. The control board 3 is used to control whether the pump body 2 operates. The pump body 2 includes a pump housing 21 and a pipe body 22 located beside the pump housing 21. The pump housing 21 is provided with an inlet 211, an outlet 212, and an impeller 213 that draws water from the inlet 211 to the outlet 212. The pipe body 22 is connected to the outlet 212 of the pump housing 21. A flow switch 8 is provided in the pipe body 22 to control the flow of water at the outlet 212. The flow switch 8 includes a valve core 81, an elastic element 82, a magnet 83, and a reed switch 20. The valve core 81 can move axially along the pipe body 22 to a first position or a second position. When the valve core 81 is in the first position, the valve core 81 opens the outlet 212. When the valve core 81 is in the second position, the valve core 81 closes the outlet 212.

[0040] The elastic element 82 acts on the valve core 81, causing the valve core 81 to always tend to move towards the second position. The magnet 83 is located inside the valve core 81, and the reed switch 20 is located on the side wall of the tube body 22, cooperating with the magnet 83 to control whether the motor of the shielded centrifugal booster pump starts.

[0041] The electrical connection between the control board 3 and the pump body 2 can refer to the prior art, and the structure of the pump body 2 can also refer to the prior art, such as the "DC permanent magnet shielded booster pump with water flow control start and forced start" published in Chinese utility model patent application number CN201920864404.3 (publication number CN210218146U).

[0042] The adapter 4 is installed in the housing 1, which is formed by the upper housing 1a and the lower housing 1b joined together. A positioning block 5 is installed on the side wall of the housing 1, which is located near the adapter 4. The adapter 4 is located near the control board 3. The output end of the adapter 4 is electrically connected to the control board 3, and the input end of the adapter 4 is connected to a wire. One end of the wire passes through the positioning block 5 of the housing 1 for connection to the mains power.

[0043] The adapter 4 is positioned near the control board 3, and the positioning block 5 is positioned near the adapter 4. This makes the wires more compact inside the pump body 2, preventing the wires from being too long and from getting tangled or knotted inside the pump body 2.

[0044] As can be seen from the above, by fixing the adapter 4 in the pump body 2, there is no need to find a separate place to put the adapter 4 when it is not in use, which can prevent loss. Furthermore, the adapter 4 is built into the pump body 2, making the overall structure of the water pump more compact.

[0045] The top wall of the pump casing 21 is higher than the top wall of the pipe body 22. The control board 3 is located on the top of the pump casing 21, and a bracket 6 is provided on the pipe body 22. The adapter 4 is mounted on the bracket 6. This makes full use of the space in the pump body 2. The control board 3 is plate-shaped and occupies little vertical space, so it is placed on the relatively tall pump casing 21. Placing the control board 3 on the pump casing 21 also facilitates the control of the motor in the pump casing 21. Mounting the bracket 6 on the pipe body 22 makes full use of the space above the pipe body 22 and does not result in a large overall volume of the pump body 2.

[0046] To facilitate the relative fixation of the bracket 6 and the tube 22, the top of the tube 22 is provided with a vertically extending connecting post 221, and the bracket 6 is provided with a connecting plate 61 located on the top of the connecting post 221. The connecting plate 61 and the connecting post 221 are connected by a first connector. In this embodiment, the first connector is a screw.

[0047] The connecting column 221 has a limiting piece 222 extending radially on its peripheral wall, and the bracket 6 has a latch 62 that can fasten the limiting piece 222. The first connecting member extends vertically, and the latch 62 extends horizontally. During installation, the latch 62 fastens the limiting piece 222 to pre-position the bracket 6 horizontally. Then, the connecting plate 61 and the connecting column 221 are connected vertically by the first connecting member. The latch 62 and the first connecting member position the bracket 6 in different directions, resulting in good positioning.

[0048] Preferably, the top of the tube 22 is provided with a support platform, on which the bracket 6 rests, so that there is a gap between the bracket 6 and the top wall of the tube 22 to allow for heat dissipation.

[0049] To facilitate operation of the control panel 3, the control panel 3 is located near the top wall of the outer casing 1. The top wall of the outer casing 1 has a perforated hole 11, and a pressing arm 12 is provided in the perforated hole 11. One end of the pressing arm 12 is connected to the wall surface of the perforated hole 11, and the other end can be deflected up and down. The control panel 3 has a contact point 30 facing the other end of the pressing arm 12. The cooperation between the pressing arm 12 and the contact point 30 adopts existing technology, which will not be described in detail here.

[0050] The shielded centrifugal booster pump built into the power adapter also includes a housing 7 in which the reed switch 20 is detachably housed. The outer peripheral wall of the tube body 22 has a horizontally extending groove 71. The housing 7 is partially detachably housed in the groove 71. A mounting plate 72 is connected to the top or bottom of the housing 7. The mounting plate 72 and the tube body 22 are detachably connected via a second connector. The second connector extends horizontally, and its extension direction is perpendicular to the extension direction of the groove 71. By installing the reed switch 20 in the housing 7, which is detachably mounted on the tube body 22, if the reed switch 20 malfunctions, the housing 7 can be removed, the reed switch 20 removed, a new reed switch 20 replaced, and then reinstalled on the tube body 22, without rendering the entire shielded centrifugal booster pump unusable.

[0051] In addition, the tube body 22 is provided with a groove 71, the extension direction of the groove 71 is perpendicular to the extension direction of the second connector. The groove 71 and the second connector are positioned in different directions to ensure that the accommodating box 7 is firmly assembled on the tube body 22. Since the accommodating box 7 is partially detachably embedded in the groove 71, the mounting plate 72 is detachably installed on the tube body 22 through the second connector, so that the accommodating box 7 can be removed from the tube body 22.

[0052] To facilitate the installation of the receiving box 7 onto the tube body 22, the mounting plate 72 is provided with a sleeve 73 extending along the extension direction of the second connector. The outer wall of the tube body 22 is provided with a post 224 that can be inserted into the sleeve 73. The sleeve 73 and the post 224 are detachably connected by a second connector, which is a screw. During installation, the receiving box 7 is first partially embedded in the groove 71, and the post 224 is inserted into the sleeve 73, thus pre-positioning the receiving box 7 onto the tube body 22. Then, the sleeve 73 and the post 224 are connected by the second connector, thus securely installing the receiving box 7 onto the tube body 22. The receiving box 7 is provided with a slot 74 for the reed switch 20 to be detachably installed.
