Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a wastewater buffer tank and an automatic base station for cleaning equipment. Background Technology

[0002] Many base stations with automated cleaning equipment are equipped with automatic sewage (water) discharge devices. In particular, commercial cleaning equipment may need to discharge more than 50L of sewage at a time, which is mixed with a large number of impurities, placing high demands on the sewage treatment capacity of the base station.

[0003] When some existing base stations discharge sewage, the sewage contains a large number of impurities, which can affect the performance of sewage treatment equipment and cause the sewage pumps of the sewage treatment equipment to experience a certain degree of performance degradation. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater buffer tank and an automatic base station for cleaning equipment to solve the problem of declining wastewater treatment performance.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A wastewater buffer tank, comprising:

[0007] Box;

[0008] A filter assembly is disposed inside the housing and is used to divide the housing into a first cavity and a second cavity;

[0009] A sewage discharge assembly is provided for discharging sewage from the tank. Sewage enters the tank through the first cavity, and the sewage discharge assembly is disposed in the second cavity and is used to discharge filtered sewage.

[0010] A liquid level detection assembly includes a first liquid level device and a second liquid level device; the first liquid level device is disposed in the first cavity and is used to detect the liquid level inside the first cavity to detect whether the sewage buffer tank is draining abnormally; the second liquid level device is disposed in the second cavity and is used to detect the liquid level inside the second cavity to control the opening and closing of the sewage discharge assembly.

[0011] Preferably, the sewage discharge assembly includes a water pump, the water pump inlet is located in the second cavity, and the water pump outlet has a drain port, which passes through the filter assembly to discharge sewage to the outside.

[0012] Preferably, the filter assembly includes a first filter screen and a second filter screen;

[0013] The first filter screen has a first opening at its bottom, and the second filter screen has a second opening at its top. The first opening and the second opening form a channel for accommodating the drain interface.

[0014] Preferably, a guide assembly is provided inside the housing, and the filter assembly is detachably connected to the housing through the guide assembly.

[0015] Preferably, it also includes a magnetic connector installed on the housing, the magnetic connector being electrically connected to the sewage discharge assembly and the liquid level detection assembly, the magnetic connector being at least used for magnetic connection with external devices to provide power and / or communication and control to both.

[0016] Preferably, the magnetic connector has at least one set of electrodes for in-situ detection of the sewage buffer tank and external equipment, to detect whether the sewage buffer tank is correctly installed on the external equipment.

[0017] Preferably, the housing is provided with a water inlet connected to the interior of the first cavity; and / or,

[0018] The drainage interface is equipped with a drainage pipe.

[0019] An automatic base station for cleaning equipment includes:

[0020] The aforementioned wastewater buffer tank;

[0021] The base station body has a accommodating chamber for housing the sewage buffer tank.

[0022] Preferably, the accommodating chamber is provided with a magnetic base, which is magnetically connected to the magnetic connector.

[0023] Preferably, after the wastewater buffer tank is installed into the containment chamber, the inlet is at least partially located outside the containment chamber; and / or,

[0024] After the sewage buffer tank is installed in the containment chamber, the drain pipe extends to the outside through the wall of the base station body to discharge sewage to the outside of the base station body.

[0025] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0026] This wastewater buffer tank filters wastewater through a filtration assembly before discharge, reducing the amount of debris drawn into the discharge assembly and ensuring its discharge performance. A first liquid level device detects whether the liquid level inside the first chamber is high, checking for issues such as excessive wastewater entering the buffer tank per unit time, filter assembly blockage, and discharge assembly malfunction. Simultaneously, a second liquid level device detects whether the liquid level inside the second chamber is low, checking for issues such as filter assembly blockage and insufficient wastewater entry. This improves the self-diagnosis effect of the wastewater buffer tank and enhances its practicality.

[0027] Furthermore, after the magnetic connector is magnetically connected to the external device, it can supply power to the sewage discharge component and the liquid level detection component. The liquid level detection component can also interact with the external device via electrical signals. After being powered on, the liquid level detection component can transmit the detection signal to the control unit of the external device, thereby controlling the opening and closing of the sewage discharge component. This prevents the sewage discharge component from continuing to operate when the sewage level inside the second chamber is too low. In addition, a set of electrodes for in-situ detection is integrated on the magnetic connector of the sewage buffer tank, which makes it easy to know whether the sewage buffer tank is in a normal installation state during use, ensuring the normal operation of the component and improving its practical effect.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0039] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0040] Reference Figures 1 to 5 This application provides a wastewater buffer tank, including: a tank body 1, a filter assembly, a sewage discharge assembly, and a liquid level detection assembly.

[0041] Specifically, the filter assembly is disposed inside the housing 1 to divide the housing 1 into a first cavity 101 and a second cavity 102; wherein, the filter assembly preferably divides the housing 1 into the first cavity 101 and the second cavity 102 in the vertical direction (i.e., the height direction of the housing 1), and the housing 1 is provided with a water inlet 105 connected to the inside of the first cavity 101. The water inlet 105 is preferably protruding from the housing 1, and the water inlet 105 includes, but is not limited to, being integrally formed and fixedly connected to the housing 1.

[0042] The sewage discharge assembly is used to discharge sewage from the tank 1. Sewage enters the tank 1 through the first cavity 101, and the sewage discharge assembly is located in the second cavity 102 to discharge the filtered sewage. The sewage discharge assembly may include a water pump 2, with its inlet located in the second cavity 102 and its outlet having a drain port 201. The drain port 201 passes through the filter assembly and discharges the sewage to the outside. Preferably, the water pump 2 is detachably installed in the second cavity 102. A clamp 106 is provided in the second cavity 102. The clamp 106 is made of a U-shaped elastic material, allowing the water pump 2 to be fixed by the elastic clamping force of the clamp 106, facilitating disassembly. Alternatively, the water pump 2 can be fixed in place using existing fixing methods such as screws; no single method is limited here.

[0043] It should be noted that the drain interface 201 is equipped with a drain pipe 202, which is preferably a flexible hose. The drain pipe 202 is arranged in a bent manner inside the first cavity 101, so that a certain length of pipe body can be reserved in the drain pipe 202 to prevent the connection between the drain pipe 202 and the drain interface 201 from being pulled when the box 1 is moved. After the drain interface 201 passes through the filter assembly, water can be led out through the drain pipe 202 to avoid the drain interface 201 discharging sewage back into the first cavity 101 after passing through the filter assembly. Of course, the position of the water pump 2 in the second cavity 102 can also be adjusted so that the drain interface 201 can be discharged directly to the outside through the drain pipe 202, avoiding the drain interface 201 discharging after passing through the filter assembly.

[0044] The liquid level detection assembly includes a first liquid level device 1011 and a second liquid level device 1021; the first liquid level device 1011 is disposed in the first cavity 101 and is used to detect the liquid level inside the first cavity 101 to detect whether the sewage buffer tank is draining abnormally; the second liquid level device 1021 is disposed in the second cavity 102 and is used to detect the liquid level inside the second cavity 102 to control the opening and closing of the sewage discharge assembly.

[0045] It should be noted that the first liquid level device 1011 is preferably located at a relatively high position on the inner wall of the first cavity 101. The first liquid level device 1011 can be connected to an external alarm device. When the sewage level in the first cavity 1011 reaches the first liquid level device 1011, the alarm device can notify the drainage equipment and remind the staff to stop discharging sewage into the first cavity 101 through sound or status light to prevent sewage overflow. Of course, the first liquid level device 1011 can also integrate an alarm unit itself. In this case, when the sewage level in the first cavity 101 reaches the first liquid level device 1011, the alarm unit will be activated. After the liquid level device 1011 is activated, it can automatically trigger an alarm without the need for an external alarm device. When the liquid level inside the first chamber 101 reaches the level of the first liquid level device 1011, it can detect that the liquid level inside the first chamber 101 is high. At this time, the sewage buffer tank is in an abnormal drainage state. The above-mentioned abnormal drainage state includes at least the following reasons: the amount of sewage entering the first chamber 101 per unit time is too large, the sewage discharge capacity of the water pump 2 is difficult to match the amount of sewage entering the first chamber 101 per unit time, or the filter component is blocked, or the water pump 2 is damaged.

[0046] The second liquid level device 1021 is preferably located at a lower position on the inner wall of the second cavity 102. The second liquid level device 1021 can control the water pump 2 to operate autonomously without external equipment or manual control signals. It can operate autonomously as long as a certain water level is reached, avoiding control failures caused by external misoperation or equipment communication abnormalities that prevent the water pump 2 from starting normally. When the liquid level inside the second cavity 102 is lower than that of the second liquid level device 1021, it can detect the low liquid level and control the water pump 2 to stop operating. Reasons for the liquid level inside the second cavity 102 being lower than that of the second liquid level device 1021 include at least a clogged filter assembly or no sewage entering the first cavity 101.

[0047] Therefore, the wastewater buffer tank filters wastewater through a filter assembly before discharging it, reducing the impurities sucked in by the discharge assembly and ensuring its discharge performance. The first liquid level device 1011 detects whether the liquid level inside the first chamber 101 is high, checking for problems such as excessive wastewater entering the wastewater buffer tank per unit time, filter assembly blockage, and discharge assembly malfunction. At the same time, the second liquid level device 1021 detects whether the liquid level inside the second chamber 102 is low, checking for problems such as filter assembly blockage and no wastewater entering the wastewater buffer tank. This improves the self-diagnosis effect of the wastewater buffer tank and enhances its practicality.

[0048] In some alternative implementations, refer to Figure 2 and Figure 3 The filter assembly includes a first filter screen 301 and a second filter screen 302. The first filter screen 301 preferably has a first opening at its bottom, which is preferably a semi-circular shape. The second filter screen 302 has a second opening at its top, which is preferably a semi-circular shape. The first opening and the second opening form a channel for accommodating the drain interface 201. This channel has a complete circular structure, allowing the drain interface 201 to pass through the filter assembly and enter the first cavity 101 on the other side from the second cavity 102.

[0049] It should be noted that when the position of the water pump 2 is adjusted so that the drain port 201 does not pass through the filter assembly and the sewage is discharged directly from the second cavity 102 to the outside, there is no need to set openings on the first filter screen 301 and the second filter screen 302.

[0050] In some alternative implementations, refer to Figure 2 and Figure 3 The housing 1 is equipped with a guide assembly 103. The filter assembly is detachably connected to the housing 1 through the guide assembly 103, so that the filter assembly can be removed from the housing 1 for cleaning.

[0051] In a practical application, the guide assembly 103 is preferably at least one set of guide rails symmetrically arranged on the inner sidewall of the housing 1. The guide rails can be U-shaped or T-shaped. Based on this application, both the first filter screen 301 and the second filter screen 302 are provided with a frame on their periphery. When the guide rail is U-shaped, the two sides of the frame of the first filter screen 301 and the second filter screen 302 are located inside the U-shaped structure of the guide rail, thereby enabling the filter assembly composed of the first filter screen 301 and the second filter screen 302 to be detachably installed in the housing 1. When the guide rail is T-shaped, the two sides of the frame of the first filter screen 301 and the second filter screen 302 are provided with T-shaped grooves adapted to the T-shaped structure, thereby enabling the filter assembly composed of the first filter screen 301 and the second filter screen 302 to be detachably installed in the housing 1.

[0052] In some optional embodiments, a magnetic connector 104 is also included, which is electrically connected to the sewage discharge assembly and the liquid level detection assembly. The magnetic connector 104 can be used to magnetically connect with external devices to provide power and / or communication and control for both. Specifically, when the magnetic connector 104 is magnetically connected to an external device, it can provide power to the sewage discharge assembly and the liquid level detection assembly. The liquid level detection assembly can also interact with the external device by exchanging electrical signals. After being powered on, the liquid level detection assembly can transmit the detection signal to the control unit of the external device, thereby controlling the opening and closing of the sewage discharge assembly and preventing the sewage discharge assembly from continuing to operate when the sewage level inside the second chamber 102 is too low.

[0053] As a preferred embodiment, the magnetic connector 104 has at least one set of electrodes for in-situ detection of the sewage buffer tank and external equipment, to detect whether the sewage buffer tank is correctly installed on the external equipment. Specifically, the in-situ detection of the sewage buffer tank and external equipment is as follows: when the sewage buffer tank is installed on the external equipment, the magnetic connector 104 is magnetically connected to the external equipment. At this time, if the set of electrodes included in the magnetic connector 104 is conductive to the external equipment, then the sewage buffer tank and the external equipment are in a correct installation state; otherwise, the sewage buffer tank is not correctly installed on the external equipment. Thus, by integrating a set of electrodes for in-situ detection on the magnetic connector 104 of the sewage buffer tank, it is convenient to know whether the sewage buffer tank is in a normal installation state during use, ensuring the normal operation of the component and improving its practical effect.

[0054] Reference Figures 4 to 5 The present invention also provides an automatic base station for cleaning equipment, comprising: a wastewater buffer tank and a base station body 4. Specifically, the base station body 4 has a accommodating chamber 401 for accommodating the wastewater buffer tank. Thus, after the wastewater buffer tank is installed in the accommodating chamber 401, it can treat the wastewater discharged from the base station body 4 before discharging it to the outside, effectively reducing impurities in the discharged wastewater.

[0055] In some alternative implementations, refer to Figure 5 The storage chamber 401 is equipped with a magnetic base 402, which is magnetically connected to the magnetic connector 104. The magnetic base 402 is electrically connected to the control unit of the base station body 4. When the magnetic base 402 is connected to the magnetic connector 104, the base station body 4 supplies power to the sewage discharge assembly and the liquid level detection assembly. Simultaneously, the base station body 4 receives liquid level detection information from the liquid level detection unit and controls the operating status of the sewage discharge assembly based on this information, thus promptly monitoring the working condition of the sewage discharge tank.

[0056] In some alternative implementations, refer to Figure 4 When the sewage buffer tank is installed in the storage chamber 401, the inlet 105 is at least partially located outside the storage chamber 401, allowing the sewage discharge structure of the base station body 4 to transport sewage into the first cavity 101 of the sewage buffer tank through the protruding inlet 105. Specifically, the working process of the base station body 4 equipped with the sewage buffer tank is as follows: When the base station body 4 needs to discharge sewage, the sewage discharge structure transports sewage to the first cavity 101 through the inlet 105. After passing through the filter assembly, the sewage enters the second cavity 102. When the sewage level inside the second cavity 102 reaches the second liquid level device 1021, the base station body 4 receives its detection signal and controls the water pump 2 to operate for sewage discharge. When the sewage level inside the first cavity 101 reaches the first liquid level device 1011, the base station body 4 receives its detection signal and will know that the sewage buffer tank is in an abnormal drainage state. The staff can stop the machine in time to check and solve the abnormal drainage problem.

[0057] It should be noted that the base station body 4 may be equipped with sound alarm and / or light alarm elements. When the base station body 4 receives the abnormal liquid level detection signal from the first liquid level device 1011, it can alert the surrounding staff through sound alarm, light alarm, or a combination of both. It can even directly cut off its own power input to stop itself. When the sewage inside the first cavity 101 of the sewage tank reaches the first liquid level device 1011, the base station body 4 is used to remind the user that the sewage buffer tank is draining abnormally and to stop the sewage from being discharged into the first cavity 1. The form of stopping the sewage from being discharged into the first cavity 1 is not limited to the types listed above, and is not the only one.

[0058] After the sewage buffer tank is installed in the containment chamber 401, the drain pipe 202 extends outward through the wall of the base station body 4 to discharge sewage outside the base station body 4. It should be noted that when the above method is used, the side wall of the base station body 4 is provided with a perforation for the drain pipe 202 to pass through; of course, the drain pipe 202 can also be set on a side wall of the box 1 located outside the containment chamber 401, in which case it is not necessary to open a perforation on the side wall of the base station body 4. The specific setting can be flexibly selected according to the actual situation.

[0059] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
