Description

Water pump

Technical Field

The utility model relates to the technical field of mechanical equipment for daily life, in particular to a water pump.

Background

The existing water pump generally comprises a suction port and a water suction device communicated with the suction port, wherein the suction device is used for sucking external water into the water tank through a water suction pipe connected with the water tank.

The water sucking device in the water pump with the existing structure is generally driven by electric power, in order to avoid the water sucking device from being damaged when the water tank is full of water, a floating ball is generally arranged in the water tank and can rise along with the rise of the liquid level in the water tank, so that the pumping port can be plugged by the floating ball before the water tank is full of water, and the water sucking device is prevented from being damaged when the water tank is full of water. However, when the water tank is full, the structure needs to be manually powered off, otherwise, the water absorbing equipment is easy to damage due to the fact that the water tank cannot be pumped through the pumping port in the working state.

Disclosure of Invention

In order to solve at least one of the problems that the existing water pump is easy to damage due to water when in use and is easy to damage due to the fact that the water tank cannot be sucked through the suction port in a working state, according to one aspect of the utility model, the water pump is provided.

The water pump comprises a water tank, wherein the water tank is provided with a first accommodating cavity, a suction port and a pipe joint, the first accommodating cavity is communicated with the outside, and the suction port is arranged at the top of the water tank; a water absorbing device capable of applying suction to the first accommodating chamber through the suction port; a float arranged in the first accommodating cavity, and a magnetic component is arranged on the float; a magnetic induction switch provided at a position of the water tank adjacent to the suction port, the magnetic induction switch being configured to be capable of inducing the magnetic member at a set distance from the magnetic member; and the control module can perform signal transmission with the magnetic induction switch, and can also perform signal transmission with the water absorption equipment. The set distance may be, for example, within 10cm, or within 5cm, preferably, within 2cm, so that the float can generally seal the suction port when the magnetic induction switch senses the float, so as to avoid damage to the pump when the pump is in use.

Therefore, the floater can rise along with the liquid level in the first accommodating cavity of the water tank, and when the floater moves to a distance smaller than a set distance from the magnetic induction switch, the magnetic induction switch can sense a magnetic component arranged on the floater, so that the control module can control the working state of the water absorption device, for example, control the water absorption device to stop working, and the water absorption device cannot suck the water tank through the suction port to be damaged under the working state when the magnetic induction switch senses the magnetic component.

In some embodiments, the magnetic component is a ferromagnetic body. Thus, the reliability of the induction magnetic component of the magnetic induction switch can be improved.

In some embodiments, a drain port for communicating the first receiving chamber with the outside is further provided in the water tank adjacent to the bottom thereof; the water outlet is provided with a switch valve which can communicate the first accommodating cavity with the outside when the water absorbing device stops working and separate the first accommodating cavity from the outside when the water absorbing device stops working. Therefore, when the water absorption equipment stops working, the switching valve is in an open state, and the liquid in the first accommodating cavity can be discharged from the water outlet under the action of the gravity of the liquid; when the water absorption device starts to work, the switching valve is in a closed state, so that liquid in the first accommodating cavity can be prevented from being discharged from the water outlet, and whether the switching valve discharges water or not can be controlled by the water absorption device.

In some embodiments, the on-off valve is a rubber valve. Therefore, the requirement of the switch valve can be met under the condition of keeping the structure of the water pump simple and low in cost.

In some embodiments, the control module is configured to control the water absorbing device to stop operating for a set time when the magnetic induction switch senses a magnetic component on the float. Therefore, when the inductive switch senses the magnetic component, the control module can control the stop time of the water absorbing equipment to ensure that the water in the water tank is completely discharged; then, when the set time is over, the water absorbing device restarts to work, so that the water in the water tank is stored again.

In some embodiments, the pump further comprises an on-off switch and a circuit board for connection to a power source; the control module and the water absorbing device are electrically connected with the circuit board. Therefore, the control module can control the water sucking device to start or stop working by controlling the water sucking device to be connected or disconnected with the on-off switch.

In some embodiments, the pump further comprises a grille cover detachably connectable to the tank, having a second receiving chamber and a first opening and at least one first through hole communicating the second receiving chamber with the outside, and the grille cover is arranged such that, when detachably connected to the tank, the suction port is located in an area surrounded by the tank and the grille cover; the second accommodation chamber and the first opening are arranged such that the float accommodated in the second accommodation chamber can move toward and away from the first opening when the grille cover is connected with the water tank.

Therefore, water can flow into the second accommodating cavity from the first accommodating cavity through the first through hole through the grid cover, so that the floater rises under the action of the buoyancy force of the liquid, and the movement track of the floater can be controlled through the grid cover. Preferably, the second accommodation chamber and the first opening are arranged such that, when the grill cover is connected to the water tank, the float accommodated in the second accommodation chamber can move toward and away from the first opening, and the suction port can be blocked when the float moves to the first opening.

In some embodiments, the pump further comprises a filter housing that is positioned around the perimeter of the grating housing. Therefore, the liquid entering the second accommodating cavity of the grid cover can be filtered through the filter cover, and the phenomenon that the smoothness of the movement of the floater under the buoyancy action of the liquid is influenced due to impurities in the liquid entering the second accommodating cavity is avoided.

In some embodiments, the magnetic component is disposed on top of the float. So that the magnetic induction switch can better induce the magnetic component.

In some embodiments, the water tank includes a tank body having a receiving groove and a second opening communicating the receiving groove with the outside; and an upper cover detachably and hermetically connected with the box body so as to cover the second opening; the upper cover surrounds the accommodating groove in the box body into a first accommodating cavity; the suction port, the water absorbing device and the magnetic induction switch are arranged on the upper cover; the pipe interface is arranged on the box body.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Fig. 1 to 4 schematically show a water pump according to an embodiment of the present utility model.

As shown in fig. 2 and 4, the water pump includes a water tank 20, a water sucking device 30, a float 40, a magnetic member 50, a magnetic induction switch 60, and a control module 70; wherein the water tank 20 is integrally formed or machined with a first receiving chamber 201, a suction port 221 for communicating the first receiving chamber 201 with the outside, and a pipe joint 211 for communicating the first receiving chamber 201 with the outside, and the suction port 221 is provided at the top of the water tank 20, the pipe joint 211 being available for connection with an external suction pipe (or a general water pipe); the water sucking device 30 can apply suction to the first accommodation chamber 201 through the suction port 221 so that the first accommodation chamber 201 having suction can suck an external object (e.g., liquid, or fine foreign substances) into the first accommodation chamber 201 through the pipe joint 211; the float 40 is provided in the first accommodation chamber 201; the magnetic member 50 is provided on the float 40; the magnetic induction switch 60 is provided at a position of the water tank 20 adjacent to the suction port 221, and the magnetic induction switch 60 is capable of inducing the magnetic member 50 on the float 40 when the distance between the float 40 and the magnetic induction switch is smaller than a set distance; the control module 70 is capable of signal transmission with the magnetic induction switch 60 and the water absorbing device 30.

Illustratively, the water absorbing device 30 may employ a water absorbing motor, or a water pump, commonly used in existing water pumps. The water sucking device 30 applies suction to the first accommodation chamber 201 through the suction port 221, for example, by sucking out the gas in the first accommodation chamber 201, puts the first accommodation chamber 201 in a negative pressure state, thereby causing an article whose outside is in an atmospheric pressure state to enter the first accommodation chamber 201 from the pipe joint 211 under the action of a pressure difference.

By way of example, the magnetic member 50 may be an object capable of generating a magnetic field, such as a magnet. Preferably, the magnetic component 50 is a strong magnet to improve the reliability of the magnetic induction switch 60 to sense the magnetic component 50.

Illustratively, the magnetic induction switch 60 employs a magnetic switch capable of sensing a magnet as is commonly used in the art.

Illustratively, the control module 70 employs a conventional PLC or MCU.

The float 40 is illustratively made of a material capable of floating on a typical liquid (e.g., water), such as plastic, foam, and the float 40 may be constructed in a conventional manner capable of floating on a typical liquid.

When the water pump is used, when the top of the liquid in the first accommodating chamber 201 of the water tank 20 can be in contact with the float 40, the float 40 can be raised along with the rise of the liquid level in the first accommodating chamber 201 of the water tank 20, and when the distance between the float and the magnetic induction switch 60 is smaller than the set distance, the magnetic induction switch 60 can sense the magnetic component 50 arranged on the float, so that the control module 70 can control the working state of the water absorbing device 30, for example, control the water absorbing device 30 to stop working, when the magnetic induction switch 60 senses the magnetic component 50, so as to avoid the water tank 20 from being damaged due to the fact that the water absorbing device 30 cannot suck the water tank 20 through the suction port 221 in the working state.

Illustratively, the set distance may be, for example, within 10cm, or within 5cm, and preferably, within 2cm, so that the float 40 is generally capable of sealing off the suction port 221 when the magnetic induction switch 60 senses the float 40 (i.e., the cross-section of the float 40 spans more than the cross-section of the suction port 221, and when the suction ports 221 are plural, the suction port 221 spans are calculated for all the suction ports 221) to avoid water damage when the pump is in use. Specifically, the distance that the magnetic induction switch 60 can sense the float 40 may be different according to the intensity of the magnetic field generated by the selected magnetic component 50, and the set distance may be shorter, for example, 2cm, 3cm when the intensity of the magnetic field generated by the magnetic component 50 is stronger, and longer, for example, 10cm when the intensity of the magnetic field generated by the magnetic component 50 is weaker. Of course, regardless of the set distance, if it is desired that the float 40 is able to block the suction port 221 when the magnetic induction switch 60 senses the magnetic member 50, this can be achieved by providing the shape of the float 40, for example, controlling the height of the float 40.

In some embodiments, as shown in fig. 1 to 3, the water tank 20 is further integrally formed or machined with a drain port 212 that communicates the first receiving chamber 201 with the outside at a position adjacent to the bottom of the water tank 20; the drain port 212 is provided with an opening/closing valve 213 capable of communicating the first accommodation chamber 201 with the outside when the water absorbing device 30 stops operating, and isolating the first accommodation chamber 201 from the outside when the water absorbing device 30 stops operating. Thereby, when the water sucking device 30 stops operating, since the switching valve 213 is in an opened state, the liquid in the first accommodation chamber 201 can be discharged from the water discharge port 212 by its own gravity; when the water sucking device 30 starts to operate, since the switching valve 213 is in the closed state, it is possible to prevent the liquid in the first accommodation chamber 201 from being discharged from the water discharge port 212, so that whether the switching valve 213 discharges water is controlled by the water sucking device 30. Preferably, the switching valve 213 is a rubber valve. Thus, the need for the on-off valve 213 can be met while keeping the pump construction compact and low cost.

In some preferred embodiments, the control module 70 is configured such that when the magnetic induction switch 60 senses the magnetic member 50 on the float 40, the control module 70 controls the water absorbing device 30 to stop operating for a set time. Thus, when the inductive switch senses the magnetic component 50 (when the water in the water tank 20 is full), the control module 70 can control the water sucking device 30 to stop working so as to ensure that the water in the water tank 20 is completely discharged; then, when the set time is over, the water absorbing device 30 resumes operation, so that the water tank 20 is re-stored with water, for example, the water absorbing device 30 may be controlled to resume operation after 15 seconds of stopping operation, or the water absorbing device 30 may be controlled to resume operation after 25 seconds of stopping operation, or the water absorbing device 30 may be controlled to resume operation after 60 seconds of stopping operation, specifically, the stopping operation time of the water absorbing device 30 may be adjusted according to the volume of the first accommodating chamber 201, and when the volume of the first accommodating chamber 201 is large, the stopping operation time of the water absorbing device 30 may be set to be longer, for example, 60 seconds; when the volume of the first accommodation chamber 201 is small, the stop time of the water absorbing device 30 may be set to be short, for example, 15 minutes.

In some preferred embodiments, as shown in FIG. 4, the pump further includes an on-off switch 81 and a circuit board 82; wherein the on-off switch 81 is used for being connected with the power supply 83, for example, electrically connected with a power supply 83 wire; the control module 70 and the water absorbing device 30 are both electrically connected to the circuit board 82. Illustratively, the on-off switch 81 may be a conventional electronic switch. Thus, the control module 70 may control the water absorbing device 30 to be powered on or off by controlling the water absorbing device 30 to be turned on or off with the on-off switch 81, thereby controlling the water absorbing device 30 to start or stop working.

In some preferred embodiments, as shown in fig. 2 and 3, the pump further includes a grating cover 91, the grating cover 91 being detachably connected to the water tank 20, and the grating cover 91 being integrally formed or fabricated with a second accommodating chamber 911 and a first opening 912 communicating the second accommodating chamber 911 with the outside, the first opening 912 being capable of allowing the float 40 to enter and exit the second accommodating chamber 911, the grating cover 91 being further integrally formed or fabricated with a first through hole 913 communicating the second accommodating chamber 911 with the outside, and the first through hole 913 being smaller in size than the float 40 so as not to allow the float 40 in the second accommodating chamber 911 to be removed from the first through hole 913; the grill cover 91 is configured such that, when the grill cover 91 is detachably connected to the water tank 20, the suction port 221 is located in a region surrounded by the water tank 20 and the grill cover 91, that is, the suction port 221 is located inside the first opening 912, and illustratively, structures capable of being detachably connected to the water tank 20, such as threads, a clamping groove, a buckle, and the like, are integrally formed, machined, or connected to the grill cover 91 at a position close to the first opening 912; the second receiving chamber 911 and the first opening 912 are provided such that the float 40 received in the second receiving chamber 911 can move toward the first opening 912 and away from the first opening 912 when the grill cover 91 is coupled to the water tank 20, for example, the second receiving chamber 911 is provided in a cylindrical shape and the float 40 is also provided in a cylindrical shape to be fitted to the second receiving chamber 911. Preferably, the second receiving chamber 911 and the first opening 912 are provided such that the float 40 received in the second receiving chamber 911 can move toward the first opening 912 and away from the first opening 912 when the grill cover 91 is coupled to the water tank 20, and the suction port 221 can be blocked when the float 40 moves to the first opening 912. Thereby, it is ensured by the grating cover 91 that water can flow from the first accommodating chamber 201 into the second accommodating chamber 911 through the first through hole 913 so that the float 40 rises under the buoyancy of the liquid, and that the movement locus of the float 40 can be controlled by the grating cover 91 so that the suction port 221 can be blocked when the float 40 is full of water in the water tank 20. Preferably, the pump further includes a filter cover provided around the outer circumference of the grill cover 91. Thereby, the liquid entering the second accommodating chamber 911 of the grating cover 91 can be filtered by the filter cover, and the liquid entering the second accommodating chamber 911 is prevented from affecting the smoothness of the movement of the float 40 under the buoyancy of the liquid due to the impurities.

In some preferred embodiments, as shown in fig. 2 and 3, the magnetic member 50 is provided on the top of the float 40, for example, may be provided on the upper surface of the top of the float 40 or may be provided on the lower surface of the top of the float 40. So that the magnetic induction switch 60 can well sense the magnetic member 50.
