These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0038] Currently, with the continuous improvement of public water supply infrastructure, the renovation of old residential areas, the construction of urban-rural integration, and the construction of rural water supply projects, pump stations are needed for secondary pressurization of water supply to meet various water supply needs.

[0039] In older residential areas, due to limited space and environmental impact, there is insufficient land available for building pump rooms; or, in case of emergency water supply pressurization, there is no temporary equipment available.

[0040] To address the need for pressurization in confined spaces or emergency water supply situations, this application provides a miniature pump house.

[0041] The miniature pump house provided in this application integrates the water pump, inlet pipe, outlet pipe, and control components into the pump house body, forming an integrated and prefabricated layout. This facilitates the overall transport and deployment of the application in confined spaces and allows for rapid deployment in locations requiring secondary pressurization, thus addressing pressurization needs in confined spaces or emergency water supply situations. The detection component uses a first pressure detection device to monitor the water pressure at the inlet. When the inlet water pressure is insufficient, the control component promptly shuts down the water pump to prevent it from running unloaded and to protect the pump.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Reference Figures 1 to 3 As shown, the miniature pump house includes: pump house body 100, water pump 200, water inlet pipe 300, water outlet pipe 400, detection component 500 and control component 600.

[0044] Reference Figure 1 and Figure 2 As shown, the pump house body 100 includes a receiving cavity 110. Exemplarily, the pump house body 100 includes a frame and sheet metal covering the surface of the frame to enclose the receiving cavity 110, wherein the frame provides structural support. The frame may be generally cuboid and can be constructed by welding several square stainless steel tubes together; the sheet metal can be connected to the frame by welding; alternatively, the sheet metal can also be connected to the frame by fasteners such as bolts or rivets.

[0045] Reference Figure 1 and Figure 2 As shown, a water pump 200 is disposed in the receiving cavity 110, and the water pump 200 includes an inlet 210 and an outlet 220. For example, the water pump 200 can be a centrifugal pump. It should be noted that a centrifugal pump uses a high-speed rotating impeller to drive the water body to rotate, generating centrifugal force, thereby throwing the water out and forming a low-pressure zone at the center of the impeller, continuously drawing in new water to achieve continuous pressurization. Further, the water pump 200 can be a horizontal centrifugal pump. It is understood that horizontal centrifugal pumps have a compact structure, facilitating integrated installation in the receiving cavity 110. For example, the base of the water pump 200 can be detachably connected to the pump house body 100; or, a bracket for connecting the water pump can be provided in the receiving cavity 110, which can be fixed to the pump house body 100, and the water pump 200 can be detachably connected to the bracket.

[0046] Reference Figure 1As shown, one end of the water inlet pipe 300 is connected to the water inlet 210, and the other end of the water inlet pipe 300 extends to the outside of the pump house body 100. For example, the water inlet pipe 300 and the water inlet 210 can be directly connected by a thread; or, the water inlet pipe 300 and the water inlet 210 can be indirectly connected by pipe fittings such as bends or straight sections. For example, the sheet metal of the pump house body 100 is provided with holes for the water inlet pipe 300 to pass through. For example, the end of the water inlet pipe 300 located outside the pump house body 100 has an external thread for detachably connecting to an external water supply line; or, the end of the water inlet pipe 300 located outside the pump house body 100 is connected to a flange for detachably connecting to an external water supply line via the flange.

[0047] Reference Figure 1 As shown, one end of the outlet pipe 400 is connected to the outlet 220, and the other end of the outlet pipe 400 extends to the outside of the pump house body 100. For example, the outlet pipe 400 and the outlet 220 can be directly connected by threads; or, the outlet pipe 400 and the outlet 220 can be indirectly connected by a pipe joint. For example, the sheet metal of the pump house body 100 has a hole for the outlet pipe 400 to pass through, and this hole and the hole for the inlet pipe 300 can be located on the same side of the pump house body 100 to facilitate pipe connection work on the same side. For example, the end of the outlet pipe 400 located outside the pump house body 100 has an external thread for detachably connecting to the upstream water supply pipeline; or, the end of the inlet pipe 300 located outside the pump house body 100 is connected to a flange for detachably connecting to the upstream water supply pipeline.

[0048] Reference Figure 1 As shown, the detection component 500 includes a first pressure detection device 510, which is used to detect the water pressure at the inlet 210. A control component 600 is located in the pump house body 100. The control component 600 is electrically connected to both the detection component 500 and the water pump 200. The control component 600 is used to control the operating state of the water pump 200 based on the detection results from the detection component 500. It should be noted that the specific configuration of the control component can be flexibly selected and configured according to specific control function requirements.

[0049] For example, the control component 600 may be a combination of relays, contactors, and related connection circuits or integrated circuits. If there is a frequency conversion control requirement for the water pump 200, the control component 600 may also include frequency converters or other related hardware to support the frequency conversion control function.

[0050] For example, refer to Figure 1 , Figure 4 and Figure 5As shown, the first pressure detection device 510 can be a normally open PNP electronic pressure switch. The first pressure detection device 510 can be set with a minimum pressure value. When the first pressure detection device 510 detects that the water pressure is equal to or less than the set minimum pressure value, the first pressure detection device 510 switches from the normally open state to the "closed" state. The first pressure detection device 510 has a probe. A hole for installing the probe of the first pressure detection device 510 can be set at the position of the water inlet pipe 300 near the water inlet 210 so that the probe can be inserted into the water inlet pipe 300.

[0051] When the first pressure detection device 510 is a PNP normally open electronic pressure switch, it has three connecting wires: two are power supply wires (typically brown and blue, with the brown wire connected to the positive terminal and the blue wire to the negative terminal), and the third is a load connection wire (typically black). The control component 600 may include a DC power supply 630, a first relay 640, and a first contactor 680. The first relay 640 includes a first coil 641 and a first normally closed contact 642; the first contactor 680 includes a fifth coil 681. The two power supply wires of the first pressure detection device 510 are connected to the positive and negative terminals of the DC power supply 630, respectively. The first coil 641 is connected in series between the load connection wire of the first pressure detection device 510 and the negative terminal of the DC power supply 630. The first normally closed contact 642 is connected in series in the power supply circuit of the fifth coil 681 to control the energization and de-energization of the fifth coil 681. The normally open contact of the first contactor 680 is connected in series in the power supply circuit of the water pump 200 to control the start and stop of the water pump 200.

[0052] When the first pressure detection device 510 detects that the water pressure is greater than the set minimum pressure value, the first pressure detection device 510 is in the open state, the first coil 641 is de-energized, the first normally closed contact 642 is in the closed state, and the power supply circuit of the fifth coil 681 is in the conducting state at the first normally closed contact 642. When the first pressure detection device 510 detects that the water pressure is less than or equal to the set minimum pressure value, the first pressure detection device 510 is closed, the first coil 641 is energized, the first normally closed contact 642 is opened, the fifth coil 681 is de-energized, and the normally open contact of the first contactor 680 is in the open state, so that the power supply circuit of the water pump 200 is in the open state, thereby causing the water pump 200 to be de-energized and stopped.

[0053] The control component 600 may further include a start button 600a and a stop button 600b, wherein the start button 600a is normally open and the stop button 600b is normally closed. The first contactor 680 includes a normally open auxiliary contact 682. Both the start button 600a and the stop button 600b are connected in series in the power supply circuit of the fifth coil 681 to control the on / off state of the power supply circuit of the fifth coil 681. The start button 600a and the normally open auxiliary contact 682 are connected in parallel for self-locking of the first contactor 680. It is understood that the start button 600a is used to start the water pump 200, and the stop button 600b is used to manually de-energize and stop the water pump 200.

[0054] The miniature pump house provided in this application integrates the water pump 200, inlet pipe 300, outlet pipe 400, and control component 600 into the pump house body 100, forming an integrated and prefabricated layout. This facilitates the overall transport of the application to confined spaces for use and allows for rapid deployment in locations requiring secondary pressurization, thus addressing pressurization needs in confined spaces or emergency water supply situations. The detection component 500 detects the water pressure at the inlet 210 via the first pressure detection device 510. When the water pressure at the inlet 210 is insufficient, the control component 600 promptly shuts down the water pump 200 to prevent it from running unloaded and to protect the pump 200.

[0055] Reference Figure 1 As shown, in some embodiments, the detection component 500 includes a second pressure detection device 520, which is used to detect the water pressure at the outlet 220. Thus, the second pressure detection device 520 facilitates the real-time provision of a water pressure detection signal at the outlet 220 to the control component 600, enabling automated control operations. When the water pressure detected by the second pressure detection device 520 is greater than or equal to a set value, the water pump 200 is powered off and shut down. Therefore, through the second pressure detection device 520 and the control component 600, automated pressure stabilization control of the outlet 220 is achieved.

[0056] For example, refer to Figure 1 , Figure 4 and Figure 5As shown, the second pressure detection device 520 can be a normally open PNP electronic switch. The second pressure detection device 520 can be set to a maximum pressure value. When the water pressure detected by the second pressure detection device 520 is greater than or equal to the set maximum pressure value, the second pressure detection device 520 switches to the "closed" state. The second pressure detection device 520 has a probe. A hole for installing the probe of the second pressure detection device 520 can be provided at the position of the water outlet 400 near the water outlet 220 so that the probe can be inserted into the water outlet 400. Alternatively, a pipe connector that can connect the water outlet 220 and the water outlet 400 and can also connect the probe can be provided to connect the probe.

[0057] When the second pressure detection device 520 is a PNP normally open electronic switch, it has three connecting wires: two power lines (typically brown and blue, with the brown wire usually connected to the positive terminal and the blue wire to the negative terminal), and a third load connection wire (typically black). The control component 600 may include a DC power supply 630, a second relay 650, and a first contactor 680. The second relay 650 includes a second coil 651 and a second normally closed contact 652, and the first contactor 680 includes a fifth coil 681. The two power lines of the second pressure detection device 520 are connected to the positive and negative terminals of the DC power supply 630, respectively. The second coil 651 is connected in series between the load connection wire of the second pressure detection device 520 and the negative terminal of the DC power supply 630. The second normally closed contact 652 is connected in series in the power supply circuit of the fifth coil 681 to control the energization and de-energization of the fifth coil 681. The normally open contact of the first contactor 680 is connected in series in the power supply circuit of the water pump 200 to control the start and stop of the water pump 200.

[0058] When the second pressure detection device 520 is less than the set maximum pressure value, the second pressure detection device 520 is in the off state, the second coil 651 is de-energized, the second normally closed contact 652 is in the closed state, and the power supply circuit of the fifth coil 681 is in the conducting state at the position of the second normally closed contact 652.

[0059] When the second pressure detection device 520 is greater than or equal to the set maximum pressure value, the second pressure detection device 520 closes, the second coil 651 is energized, the second normally closed contact 652 is opened, the fifth coil 681 is de-energized, and the normally open contact of the first contactor 680 is in the open state, so that the water pump 200 is de-energized and stopped.

[0060] In addition, the first pressure detection device 510 and the second pressure detection device 520 can also be mechanical pressure switches. It should be noted that mechanical pressure switches use water pressure to drive the corresponding mechanical structure to adjust the position of the corresponding contacts in order to control the on / off state of the circuit where the contacts are located.

[0061] Reference Figure 1 and Figure 2 As shown, in some embodiments, the miniature pump house of this application further includes a pressure tank 700, which is disposed in the receiving cavity 110, and the water outlet pipe 400 and the water outlet 220 are both connected to the pressure tank 700. In this way, by buffering a small amount of water through the pressure tank 700, it is beneficial to stabilize the pressure of the water supplied by the water outlet pipe 400.

[0062] For example, the outlet 220, the outlet pipe 400, and the pressure tank 700 can be connected by a pipe connector; further, the pipe connector is a five-way connector 800, which has five interconnected interfaces: one interface for connecting to the outlet 220, another interface for connecting to the pressure tank 700 (both the inlet and outlet of the pressure tank 700 can pass through this interface), another interface for connecting to the outlet pipe 400, another interface for connecting to the probe of the second pressure detection device 520, and a third connector for connecting to a pressure gauge, which is used to detect and display the pressure value of the outlet 220.

[0063] Reference Figure 1 and Figure 2 As shown, in some embodiments, the outlet 220 is located at the top of the water pump 200, and the pressure tank 700 is located on the upper side of the water pump 200. This allows the water in the pressure tank 700 to have gravitational potential energy relative to the outlet 220. Especially when the water pump 200 is a centrifugal pump, the pressure tank 700 helps ensure that the chamber of the water pump 200 is filled with water, preventing air from entering the water pump 200 and facilitating stable operation of the water pump 200.

[0064] Reference Figure 1 As shown, in some embodiments, the pump house body 100 has a water collection tank 140 located below the water pump 200. The water collection tank 140 has a drain outlet 141 that communicates with the outside of the pump house body 100. For example, a humid environment may cause condensation to form inside the pump house body 100, or there may be leakage at the corresponding pipe joints. This application, by providing the water collection tank 140 and the drain outlet 141, facilitates the timely discharge of water generated in the pump house body 100, preventing the water pump 200 from being submerged in water, thus protecting the water pump 200.

[0065] For example, a water collection tank 140 can be constructed by sheet metal enclosure, and a pipe for extending outward from the pump house body 100 can be provided at the drain outlet 141 to connect to the external drainage pipeline.

[0066] For example, the control component 600 is located above the water pump for waterproofing.

[0067] Reference Figure 1 As shown, the miniature pump house of this application also includes a motor bracket 142. The water pump 200 includes a motor 230, which is connected to the motor bracket 142 and fastened to the motor bracket 142 by bolts. The motor bracket 142 is used to mount the motor 230 above the water collection tank 140. Thus, the water pump is fixed by connecting the motor 230 to the motor bracket 142, maintaining the water pump 200 above the water collection tank 140. For example, a buffer pad can be provided between the water pump 200 and the motor bracket 142 to reduce vibration noise. For example, the pump house body 100 has a frame, and a water collection tank is formed by enclosing sheet metal at the bottom of the frame; at least a portion of the motor bracket 142 is fixed to the frame by welding or fasteners to ensure the motor bracket 142's support capacity for the water pump 200.

[0068] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the detection component 500 further includes a water accumulation detection device 530, which is disposed in the receiving cavity 110 and is used to detect the amount of water accumulated in the water collection tank 140. The water accumulation detection device 530 is electrically connected to the control component 600, which is used to control the operating state of the water pump 200 based on the detection result of the water accumulation detection device 530. This facilitates automatic power-off and shutdown of the water pump 200 when the water in the water collection tank 140 reaches a certain height, thus protecting the water pump 200. For example, this provides safety protection for the water pump 200 in the event of severe equipment leakage or flooding of the site.

[0069] For example, the water accumulation detection device 530 can be a normally open water immersion sensor. The normally open water immersion sensor includes two power connection lines, one common terminal connection line, one normally open terminal connection line, and two probes (or electrodes or probes). The two power connection lines are used to connect to the positive and negative terminals of a power source, respectively. When the two probes are not immersed in water, the common terminal connection line and the normally open terminal connection line are disconnected (for ease of description, this state will be referred to as the water accumulation detection device 530 being disconnected). When the two probes are immersed in water, the common terminal connection line and the normally open terminal connection line are closed (for ease of description, this state will be referred to as the water accumulation detection device 530 being closed).

[0070] For example, a bracket for supporting the water accumulation detection device 530 can be provided on the side wall of the water collection tank 140 or the inner wall of the receiving cavity 110, so that the two probes of the water accumulation detection device 530 are positioned toward the water collection tank 140 and at least a portion of the two probes are inserted into the water collection tank 140 to contact the water accumulation in the water collection tank 140.

[0071] When the water accumulation detection device 530 is a normally open water immersion sensor, the control component 600 may include a DC power supply 630, a third relay 660, and a first contactor 680. The third relay 660 includes a third coil 661 and a third normally closed contact 662, and the first contactor 680 includes a fifth coil 681. The normally open contact of the first contactor 680 controls the on / off state of the power supply circuit of the water pump 200. The two power lines of the water accumulation detection device 530 are connected to the positive and negative terminals of the DC power supply 630, respectively.

[0072] The third coil 661 is connected in series between the common terminal connection line of the water accumulation detection device 530 and the positive terminal of the DC power supply 630. The normally open terminal connection line of the water accumulation detection device 530 is connected to the negative terminal of the DC power supply 630 so as to control the power supply of the third coil 661 through the water accumulation detection device 530.

[0073] When the water level in the water collection tank 140 is low or there is no water, the two probes of the water accumulation detection device 530 are not immersed in the water; the water accumulation detection device 530 is disconnected, the third coil 661 is de-energized, the third normally closed contact 662 is in a closed state, and the power supply circuit of the fifth coil 681 is in a conductive state at the third normally closed contact 662.

[0074] When the water in the water collection tank 140 is large enough to immerse the two probes of the water accumulation detection device 530, the water accumulation detection device 530 closes, the third coil 661 is energized, the third normally closed contact 662 turns to the open state, the fifth coil 681 is de-energized, the normally open contact of the first contactor 680 opens, and the water pump 200 is de-energized and stops.

[0075] Alternatively, the water accumulation detection device 530 can also be a float electronic switch. Understandably, a float electronic switch can control the opening and closing of its corresponding contacts based on the water level, thereby controlling the continuity of the circuit corresponding to those contacts. The wiring method of the float electronic switch will not be elaborated here.

[0076] Reference Figures 1 to 3As shown, in some embodiments, the miniature pump house of this application further includes a hatch 150, and the receiving cavity 110 has a doorway 111. The hatch 150 is movably disposed on the pump house body 100 to open and close the doorway 111. Exemplarily, the hatch 150 may be hinged to the pump house body 100; or, the hatch 150 may be slidably connected to the pump house body 100. The hatch 150 may have explosion-proof glass to facilitate observation of the receiving cavity 110 through the explosion-proof glass. Thus, by providing the hatch 150, it is convenient to open the receiving cavity 110 to inspect or maintain the relevant equipment in the receiving cavity.

[0077] The detection assembly 500 also includes a hatch position detection device 540, which can be installed on the hatch 150 or on the pump house body 100. For example, in the case of a through-beam photoelectric switch type, the hatch position detection device 540 may consist of two parts that need to cooperate with each other. One part can be installed on the hatch 150, and the other part can be installed on the pump house body 100. The hatch position detection device 540 is used to detect the opening and closing of the hatch 150.

[0078] Thus, the hatch position detection device 540 can provide the control component 600 with a detection signal in real time to reflect the opening and closing status of the hatch 150, thereby providing the hardware conditions for the control component 600 to automatically control the opening, closing or starting and stopping of related devices according to the opening and closing status of the hatch 150.

[0079] Reference Figure 1 and Figure 3 As shown, in some embodiments, the miniature pump room of this application also includes a lighting lamp 112, which is disposed in the receiving cavity 110. In this way, by providing the lighting lamp 112, it is convenient to provide illumination when inspecting or maintaining the inside of the receiving cavity 110, so as to facilitate the inspection and maintenance of related equipment and components inside the receiving cavity 110 in a dark environment.

[0080] Furthermore, the opening and closing of the lighting 112 can be associated with the opening and closing of the hatch 150. When the hatch 150 is open, the control component 600 controls the lighting 112 to turn on; when the hatch 150 is closed, the control component 600 controls the lighting 112 to turn off, so that the control component 600 automatically controls the opening or closing of the lighting 112 according to the opening and closing of the hatch 150.

[0081] For example, refer to Figure 1 , Figure 3 and Figure 6As shown, the hatch position detection device 540 is a PNP normally closed inductive proximity switch. The hatch position detection device 540 can be installed on the pump house body 100. When the hatch 150 is open, the hatch position detection device 540 is not triggered and the hatch position detection device 540 is closed; when the hatch 150 is closed, the hatch position detection device 540 is triggered and the hatch position detection device 540 is disconnected.

[0082] When the hatch position detection device 540 is a PNP normally closed proximity switch, the control component 600 may include a DC power supply 630, a fourth relay 670, and a second contactor 690a. The fourth relay 670 includes a fourth coil 671 and a first normally open contact 672; the second contactor 690a includes a sixth coil 690a1. The hatch position detection device 540 has three connecting lines: two are power supply lines, connected to the positive and negative terminals of the DC power supply 630 respectively; the third is a load connection line. The fourth coil 671 is connected in series between the load connection line of the hatch position detection device 540 and the negative terminal of the DC power supply 630. The first normally open contact 672 is connected in series in the power supply circuit of the sixth coil 690a1 to control the on / off state of the power supply to the sixth coil 690a1; the normally open contact of the second contactor 690a controls the on / off state of the power supply circuit to the lighting lamp 112, thereby controlling the opening and closing of the lighting lamp 112.

[0083] When the hatch 150 is opened, the hatch position detection device 540 closes, the fourth coil 671 is energized, the first normally open contact 672 closes, the sixth coil 690a1 is energized, the normally open contact of the second contactor 690a closes, the power supply circuit of the lighting lamp 112 is connected, and the lighting lamp 112 is turned on.

[0084] When the hatch 150 is closed, the hatch position detection device 540 is disconnected, the fourth coil 671 is de-energized, the first normally open contact 672 is disconnected to de-energize the sixth coil 690a1, and the normally open contact of the second contactor 690a is disconnected to turn off the lighting 112.

[0085] Reference Figure 1 and Figure 3 As shown, the miniature pump house of this application also includes an exhaust fan 160, which is disposed in the pump house body 100. When activated, the exhaust fan 160 is used to exhaust air from the receiving cavity 110 to the outside of the pump house body 100. For example, the pump house body 100 is provided with channels or holes for installing the exhaust fan 160, which is installed in the corresponding channels or holes. Thus, by providing the exhaust fan 160, ventilation of the receiving cavity 110 is facilitated, preventing excessive humidity of the air inside the receiving cavity 110 relative to the air outside the pump house body 100.

[0086] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the starting and stopping of the exhaust fan 160 can be linked to the opening and closing of the hatch 150. When the hatch 150 is open, the control component 600 controls the exhaust fan 160 to stop; when the hatch 150 is closed, the control component 600 controls the exhaust fan 160 to start, so that the control component 600 can automatically control the stopping or starting of the exhaust fan 160 according to the opening and closing of the hatch 150. In this way, it is advantageous to automatically start the exhaust fan 160 after the hatch 150 is closed.

[0087] For example, the door position detection device 540 is still a PNP normally closed proximity switch. The control assembly 600 includes a DC power supply 630, a fourth relay 670, and a third contactor 690b. The fourth relay 670 includes a fourth coil 671 and a second normally open contact 673; the third contactor 690b includes a seventh coil 690b1.

[0088] The two power lines of the hatch position detection device 540 are connected to the positive and negative terminals of the DC power supply 630, respectively. The fourth coil 671 is connected in series between the load connection line of the hatch position detection device 540 and the negative terminal of the DC power supply 630. The second normally open contact 673 is connected in series in the power supply circuit of the seventh coil 690b1 to control the on / off state of the seventh coil 690b1. The normally closed contact of the third contactor 690b controls the on / off state of the power supply circuit of the exhaust fan 160, thereby controlling the on / off state of the exhaust fan 160.

[0089] When the hatch 150 is opened, the hatch position detection device 540 closes, the fourth coil 671 is energized, the second normally open contact 673 closes, the seventh coil 690b1 is energized, and the normally closed contact of the third contactor 690b opens to cut off the power supply circuit of the exhaust fan 160 and shut down the exhaust fan 160.

[0090] When the hatch 150 is closed, the hatch position detection device 540 is disconnected, the fourth coil 671 is de-energized, the second normally open contact 673 is disconnected, the seventh coil 690b1 is de-energized, and the normally closed contact of the third contactor 690b is closed to conduct the power supply circuit of the exhaust fan 160 to start the exhaust fan 160.

[0091] Reference Figure 1 As shown, in some embodiments, the pump house body 100 is provided with an air intake channel 170, which connects the receiving cavity 110 and the outside of the pump house body 100. It can be understood that during the exhaust process of the exhaust fan 160, the air intake channel 170 is used for air intake to ensure air circulation.

[0092] Reference Figure 1As shown, in some embodiments, the control component 600 includes a frequency converter 610 for controlling the rotational speed of the water pump 200. Thus, by providing the frequency converter 610, the need for frequency conversion control of the water pump 200 is met, providing hardware support for the frequency conversion control of the water pump 200. For example, the pump house body 100 is provided with a bracket for connecting the frequency converter 610, which is located in the receiving cavity 110 to house the frequency converter 610.

[0093] Reference Figure 1 As shown, the control component 600 also includes a human-machine interface device 620, which is used to adjust the setpoints of the water pressure at the inlet 210 and the outlet 220. This facilitates adjustment of the corresponding water pressure setpoints to meet different water supply pressure requirements or different water pressure scenarios. For example, a PNP-type electronic pressure switch with a corresponding human-machine interface device 620 can be used as the corresponding first pressure detection device 510 or second pressure detection device 520. A bracket and window can be provided in the pump house body 100 for connecting multiple human-machine interface devices 620, so that the corresponding human-machine interface device 620 is fixed by the bracket and exposed through the window for easy setting adjustment.

[0094] Reference Figure 2 and Figure 3 As shown, in some embodiments, the miniature pump house also includes a handle 120, which is disposed on the pump house body 100. This facilitates manual movement of the miniature pump house, making it easier to adjust the installation position of this application in confined spaces.

[0095] Reference Figure 2 and Figure 3 As shown, in some embodiments, the miniature pump house also includes a wheel set 130, which is located at the bottom of the pump house body 100. This wheel set 130 facilitates short-distance transport of the miniature pump house, allowing for easy relocation and repositioning in situations requiring emergency pressurization. It also facilitates transport in narrow spaces or passageways.
