Description

Technical Field

[0001] This application belongs to the field of clean technology, and in particular relates to an automatic water injection system. Background Technology

[0002] After the cleaning unit has been running for a period of time, it needs to return to the cleaning base station. The base station's water tank then automatically replenishes the cleaning unit's water tank. The base station's water tank typically only opens the water injection component to replenish the main unit's water tank after the cleaning unit has returned, preventing leaks caused by the water injection component opening when the cleaning unit is not present. This process is primarily accomplished by an automatic water injection system. Currently available automatic water injection systems mainly use electronic detection via charging electrodes to determine if the cleaning unit has returned to the cleaning base station. Upon the cleaning unit's return, the system controls the water injection component to open and replenish the main unit's water tank. However, in actual use, it was found that this electronic detection method using charging electrodes has some drawbacks. Because the charging electrodes are relatively independent modules from the water injection components, even when the charging electrodes are in place, the water injection components may still misalign. Once the water injection components are misaligned, problems such as water leakage will occur, affecting the normal operation of the cleaning base station and the cleaning host. At the same time, since the electronic detection method uses electronic components, if the electronic components fail, it will also lead to detection failure. Therefore, the electronic detection method is prone to unreliability. Summary of the Invention

[0048] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0050] After the cleaning unit has been running for a period of time, it needs to return to the cleaning base station. The base station's water tank then automatically replenishes the cleaning unit's water tank. The base station's water tank typically only opens the water injection component to replenish the main unit's water tank after the cleaning unit has returned, preventing leaks caused by the water injection component opening when the cleaning unit is not present. This process is primarily accomplished by an automatic water injection system. Currently available automatic water injection systems mainly use electronic detection via charging electrodes to determine if the cleaning unit has returned to the cleaning base station. Upon the cleaning unit's return, the system controls the water injection component to open and replenish the main unit's water tank. However, in actual use, it was found that this electronic detection method using charging electrodes has some drawbacks. Because the charging electrodes are relatively independent modules from the water injection components, even when the charging electrodes are in place, the water injection components may still misalign. Once the water injection components are misaligned, problems such as water leakage will occur, affecting the normal operation of the cleaning base station and the cleaning host. At the same time, since the electronic detection method uses electronic components, if the electronic components fail, it will also lead to detection failure. Therefore, the electronic detection method is prone to unreliability.

[0051] Therefore, it is necessary to provide a new technical solution for an automatic water injection system to effectively improve the technical problem that the existing automatic water injection system uses electronic detection to confirm whether the cleaning host is properly installed in the cleaning base station, which is prone to unreliable detection.

[0052] like Figures 1 to 4 As shown, in one embodiment, this application provides an automatic water injection system 1. The automatic water injection system 1 may specifically include a cleaning base station 100 with a base station water tank 110 and a cleaning host 200 with a host water tank 210. Specifically, the cleaning base station 100 may be provided with a host storage slot 120 to accommodate the cleaning host 210. A base station water injection component 130 is disposed within the host storage slot 120. The base station water injection component 130 includes a base station water inlet 11 communicating with the base station water tank 110 and a first spring sealing structure 131 that movably seals the base station water inlet 11. Specifically, the cleaning host 200 may be provided with a host water injection component 220, which includes a host water inlet 21 communicating with the host water tank 210 and a second spring sealing structure 221 that movably seals the host water inlet 21. When the cleaning host 200 is assembled in the host storage slot 120, the host water injection component 220 can be inserted and cooperated with the base station water injection component 130. Under the force of the insertion and cooperation, the first spring sealing structure 131 and the second spring sealing structure 221 are squeezed respectively to open the corresponding base station water injection port 11 and host water injection port 21, so as to realize the automatic water injection operation of the base station water tank 110 to the host water tank 210.

[0053] It is understood that the automatic water injection system 1 of this application embodiment is mainly used in the automatic water replenishment operation of the cleaning host 200. The cleaning host 200 can generally be a cleaning robot, which can automatically move into the host storage slot 120 of the cleaning base station 100. Since the bottom wall of the host storage slot 120 is generally slightly higher than the ground, a ramp 121 can be provided at the opening of the host storage slot 120 to facilitate the automatic movement of the cleaning host 200 into the host storage slot 120 via the ramp 121. The installation position of the main unit water injection component 220 on the cleaning main unit 200 should correspond to the installation position of the base station water injection component 120 in the main unit receiving slot 120, so that when the cleaning main unit 200 is assembled in the main unit receiving slot 120, the main unit water injection component 220 and the base station water injection component 120 are directly opposite each other and plug into each other. Therefore, preferably, the main unit water injection component 220 should be located on the outer wall of the cleaning main unit 200, and the base station water injection component 120 should be located on the inner wall of the main unit receiving slot 120, so as to facilitate side insertion. The method of cooperation allows the main unit water injection component 220 to quickly and directly engage with the base station water injection component 120 when the main unit storage slot 120 is in place. At this time, under the force of the engagement, the first spring sealing structure 131 and the second spring sealing structure 221 are squeezed respectively to open the corresponding base station water injection port 11 and main unit water injection port 21, so that the main unit water injection component 220 and the base station water injection component 120 are connected, thereby realizing the automatic water injection operation of the base station water tank 110 to the main unit water tank 210.

[0054] In this way, the technical solution of this application embodiment ensures through a mechanical structure that the base station water tank 110 can only automatically fill the host water tank 210 when the cleaning host 200 is assembled in the host storage slot 120, which can effectively avoid the unreliability problems caused by the existing electronic detection method.

[0055] In some examples, such as Figure 2 , Figure 3 and Figure 4As shown, the base station water injection assembly 130 specifically includes a base station water injection housing 132 with a built-in base station water injection channel 12. The base station water injection housing 132 also has a plug-in part 13 that can be plugged into and cooperate with the host water injection assembly 220. The end face of the plug-in part 13 has a base station water injection port 11 that is connected to the base station water injection channel 12. The end of the base station water injection channel 12 away from the base station water injection port 11 is connected to the base station water tank 110, so that the base station water injection port 11 is connected to the base station water tank 110 through the base station water injection channel 12. The first spring sealing structure 131 is elastically assembled in the base station water injection channel 12 to movably seal the base station water injection port 11. In this way, through the above structural arrangement, the water in the base station water tank 110 can reach the vicinity of the base station water inlet 11 through the base station water inlet channel 12. When the first spring sealing structure 131 is not subjected to external force, it can abut against and block the base station water inlet 11 under its own elastic force, so that the water in the base station water inlet channel 12 will not flow out through the base station water inlet 11. When the first spring sealing structure 131 is subjected to external force, and the external force is greater than its own elastic force, it will move away from the base station water inlet 11, so that the base station water inlet 11 will open. At this time, the water in the base station water inlet channel 12 can flow out through the base station water inlet 11.

[0056] In some examples, such as Figure 2 , Figure 3 and Figure 4 As shown, the first spring sealing structure 131 specifically includes a first rubber plug 1311 and a first spring 1312. One end of the first rubber plug 1311 is elastically fitted into the base station water injection channel 12 via the first spring 1312, so that under the elastic force of the first spring 1312, the other end of the first rubber plug 1311 abuts against and seals the base station water injection port 11. Further, the first spring sealing structure 131 also includes a spring cover 1313 with a water-permeable hole, which is installed at the end of the base station water injection channel 12 away from the base station water injection port 11. The first rubber plug 1311 includes an abutting portion 13111 and a connecting portion 13112 connected together. The radial cross-sectional area of ​​the abutting portion 13111 is larger than the radial area of ​​the connecting portion 13112, so that a sealing device is formed at the junction between the abutting portion 13111 and the connecting portion 13112. The step abutment surface; a first spring 1312 is sleeved on the connecting part 13112, and the end of the connecting part 13112 away from the abutment part 13111 passes through the spring cover 1313, so that one end of the first spring 1312 abuts the spring cover 1313, and the other end of the first spring 1312 abuts the step abutment surface, so that under the elastic force of the first spring 1312, the end of the abutment part 13111 away from the connecting part 13112 abuts the water inlet 11 of the sealing base station.

[0057] It is understandable that the base station water-filled casing 132 can be designed as a single unit, or as... Figure 4The design employs a split structure to facilitate the assembly of the first spring sealing structure 131. Specifically, the base station water-filling housing 132 may include a front water-filling housing 1321 and a rear water-filling housing 1322, which are assembled together via a snap-fit ​​connection to form the base station water-filling channel 12. To ensure a tight seal between the two, a sealing ring 1323 is provided at the connection point. Furthermore, the insertion part 13 may protrude from the front water-filling housing 1321, and a soft rubber part 14 may be fitted onto the outer periphery of the insertion part 13 to allow for a tighter connection between the insertion part 13 and the main unit water-filling assembly 220.

[0058] In some examples, such as Figure 2 , Figure 5 and Figure 6 As shown, the main unit water injection assembly 220 also includes a main unit water injection housing 222 with a built-in main unit water injection channel 22. The main unit water injection housing 222 has a plug groove 23 that can be plugged into the plug part 13. The bottom wall of the plug groove 23 has a main unit water injection port 21 that communicates with the main unit water injection channel 22. The end of the main unit water injection channel 22 away from the main unit water injection port 21 is connected to the main unit water tank 210, so that the main unit water injection port 211 is connected to the main unit water tank 210 through the main unit water injection channel. The second spring sealing structure 221 is elastically fitted in the main unit water injection channel 22 to movably block the main unit water injection port 21. When the plug groove 23 and the plug part 13 are plugged into each other, the plug part 13 can abut against and squeeze the second spring sealing structure 221, so that the second spring sealing structure 221 can movably open the main unit water injection port 21. In this way, with the above structural arrangement, when the second spring sealing structure 221 is not subjected to external force, it can abut against and block the main unit water inlet 21 under its own elastic force, and external water cannot flow into the main unit water inlet channel 22 through the main unit water inlet 21. When the second spring sealing structure 221 is subjected to external force, and the external force is greater than its own elastic force, it will move away from the main unit water inlet 21, so that the main unit water inlet 21 opens. At this time, external water can flow into the main unit water inlet channel 12 through the main unit water inlet 21 and flow into the main unit water tank 210 through the main unit water inlet channel 12.

[0059] In some examples, such as Figure 2 , Figure 5 and Figure 6As shown, the second spring sealing structure 221 may specifically include a second rubber plug 2211 and a second spring 2212. One end of the second rubber plug 2211 is elastically fitted into the host water inlet channel 22 via the second spring 2212, so that under the elastic force of the second spring 2212, the other end of the second rubber plug 2211 abuts against and blocks the host water inlet 21. Further, the end face of the second rubber plug 2211 facing the host water inlet 21 is provided with a rubber plug pin 2213 that is inserted into the base station water inlet 11. When the insertion groove 23 and the insertion part 13 are inserted into each other, the rubber plug pin 2213 is inserted into the base station water inlet 11 and abuts against and squeezes the first spring sealing structure 131, so that the first spring sealing structure 131 can be moved to open the base station water inlet 11.

[0060] It is understandable that the main unit's water-filled casing 222 can be designed as a single piece, or as... Figure 6 The design employs a split structure to facilitate the assembly of the second spring sealing structure 221. Specifically, the main unit water-filling housing 222 may include a front water-filling housing 2221 and a rear water-filling housing 2222, which are assembled together via a snap-fit ​​connection to form the main unit water-filling channel 22. Furthermore, the insertion slot 23 may protrude from the front water-filling housing 2221.

[0061] In some examples, such as Figures 1 to 6As shown, a further structural design can be made as follows: the main unit water injection component 220 can be inserted and engaged with the base station water injection component 130 when the cleaning main unit 200 is assembled in the main unit storage slot 120. Under the force of the insertion and engagement, the second spring sealing structure 221 and the first spring sealing structure 131 are squeezed in sequence to open the corresponding main unit water injection port 21 and the base station water injection port 11, thereby realizing the automatic water injection operation of the base station water tank 110 to the main unit water tank 210. In this way, through the above structural design, the main unit water injection component 220 and the base station water injection component 130 are only fully inserted and engaged to determine that the cleaning main unit 200 is assembled in the main unit storage slot 120. Only then can the second spring sealing structure 221 and the first spring sealing structure 131 be squeezed in sequence under the force of the insertion and engagement to open the corresponding main unit water injection port 21 and the base station water injection port 11, thereby realizing the automatic water injection operation of the base station water tank 110 to the main unit water tank 210. If only the main unit water injection component 220 and the base station water injection component 130 are fully inserted and engaged, it will be determined that the cleaning main unit 200 is assembled in the main unit storage slot 120. Only then can the second spring sealing structure 221 and the first spring sealing structure 131 be squeezed in sequence under the force of the insertion and engagement to open the corresponding main unit water injection port 21 and the base station water injection port 11, thereby realizing the automatic water injection operation of the base station water tank 110 to the main unit water tank 210. If the connection is made but not fully inserted, only the second spring sealing structure 221 may be compressed, opening the main unit water inlet 21, while the first spring sealing structure 131 remains uncompressed. Consequently, the base station water inlet 11 will not open, and the base station water tank 110 will be unable to automatically fill the main unit water tank 210. This aligns with the current situation where the cleaning main unit 200 is not properly assembled within the main unit storage slot 120, preventing the base station water tank 110 from automatically filling the main unit water tank 210. Furthermore, the fact that the base station water inlet 11 is not open also prevents water leakage during this process. Therefore, the above structural design can further improve the accuracy of determining whether the cleaning main unit 200 is properly assembled within the main unit storage slot 120. Furthermore, the elastic force of the second spring 2212 can be designed to be less than that of the first spring 1312, and the elastic force of the first spring 1312 can be less than the force of the cleaning host 200 retracting. This ensures that the rubber plugs are always pushed open in the order that the second rubber plug 2211 is pushed open first, followed by the first rubber plug 1311. When the cleaning host 200 exits the cleaning base station 100, the first rubber plug 1311 closes first, followed by the second rubber plug 2211, preventing water leakage from the base station water inlet 11 when the cleaning host 200 leaves the cleaning base station 100. If the cleaning host 200 is not properly positioned, and the host water inlet 21 is not aligned with or fully in place with the base station water inlet 11, the first rubber plug 1311 will not be pushed open, and the base station water inlet 11 will remain sealed, preventing water injection and thus avoiding water leakage.

[0062] In some examples, such as Figure 2 , Figure 7 and Figure 8As shown, the cleaning base station 100 also includes a water-blocking tank bracket 140 with a buffer water chamber 141. The base station water tank 110 is mounted and fixed on the water-blocking tank bracket 140, and the buffer water chamber 141 is located directly below the bottom outlet 111 of the base station water tank 140. The buffer water chamber 141 is connected to the bottom outlet 111 and also connected to the base station water inlet 11, so that the base station water inlet 11 is connected to the base station water tank 110 through the buffer water chamber 141. Furthermore, an elastic rubber plug structure 112 is installed on the side of the bottom outlet 111 away from the buffer water chamber 141 to movably seal the bottom outlet 111. Furthermore, a base station water blocking seat 142 is also installed on the water blocking box bracket 140. The base station water blocking seat 142 is located in the buffer water chamber 141. When the base station water tank 110 is installed and fixed on the water blocking box bracket 140, the base station water blocking seat 142 abuts against the elastic rubber plug structure 112, so that the elastic rubber plug structure 112 can open the bottom water outlet 111.

[0063] Understandably, the top water inlet of the base station water tank 110 is designed with a sealing rubber plug for easy sealing, facilitating daily water filling. The bottom water outlet 111 of the base station water tank 110 is sealed with an elastic rubber plug structure 112, ensuring the water tank remains sealed when lifted. During assembly with the water-blocking bracket 140, the water outlet is opened by the base station water-blocking seat 142. Specifically, the buffer water chamber 141 may have an outlet on its bottom side, which can be connected to the base station water inlet 11 via a first connecting pipe 150.

[0064] In some examples, such as Figure 2 , Figure 7 and Figure 8 As shown, the base station water-blocking base 142 may specifically include a water-blocking base body 1421 and a hollow water-blocking column 1422 with a drainage channel (not shown in the figure). A receiving groove 14211 is installed on the side of the water-blocking base body 1421 facing the bottom outlet 111. Several through holes 14212 are formed through the side wall of the receiving groove 14211, and a drainage hole (not shown in the figure) is formed through the bottom wall of the receiving groove 14211. One end of the hollow water-blocking column 1422 is fixed to the bottom wall of the receiving groove 14211, and one end of the drainage channel is connected to the drainage hole. The other end of the hollow water-blocking column 1422 has a water inlet hole (not shown in the figure) connected to the drainage channel. When the base station water tank 110 is installed and fixed on the water-blocking tank bracket 140, the other end of the hollow water-blocking column 1422 can be inserted into the bottom outlet 111 and abut against the elastic rubber plug structure 112, causing the elastic rubber plug structure 112 to open the bottom outlet 111. In this way, through the above structural arrangement, a system can be formed as follows... Figure 7The solid arrow indicates the drainage path, which is the same as the dashed arrow indicates the air intake path. When the base station water tank 110 is placed into the water-blocking bracket 140, the elastic rubber plug structure 112 on the bottom outlet 111 is pushed open by the base station water-blocking seat 142, and water begins to leak into the buffer water chamber 141. Before the cleaning base station 100 and the cleaning host 200 are connected, the base station water inlet 11 is sealed, and water cannot continue to flow out. It can only be stored in the buffer water chamber 141, causing the water level in the buffer water chamber 141 to rise. After rising to a certain level, the water level will be sealed off. Figure 7 The air intake line is indicated by the dashed arrow. At this point, since the base station water tank 110 cannot obtain supplemental air from the outside, according to the law of atmospheric pressure, the base station water tank 110 will no longer discharge water (one atmosphere of pressure can support a 10.13M water column, which fully meets our water tank design requirements). When the cleaning base station 100 is connected to the cleaning host 200, the water in the buffer water chamber 141 flows through the first connecting pipe 150 into the base station water inlet 11, then into the host water inlet 21, and finally into the host water tank 210. This causes the water level in the buffer water chamber 141 to drop, exposing the aforementioned air intake line again. The base station water tank 110 can then continue to leak water into the buffer water chamber 141, ensuring that the buffer water chamber 141 always maintains a certain level of clean water storage.

[0065] In addition, in the above example, the structural design of the water-blocking seat 142 in conjunction with the buffer water chamber 141 allows the water in the base station water tank 110 to be partially buffered in the buffer water chamber 141 before automatically flowing to the base station water inlet 11 under the action of gravity. Since the water in the buffer water chamber 141 is much less than the water in the base station water tank 110, the water pressure flowing from the buffer water chamber 141 to the base station water inlet 11 is much less than the water pressure flowing directly from the base station water tank 110 to the base station water inlet 11. Thus, the structural design of the water-blocking seat 142 in conjunction with the buffer water chamber 141 ensures that the base station water inlet 11 can smoothly and uniformly discharge water during the water injection operation.

[0066] In some examples, such as Figure 2 , Figure 9 and Figure 10As shown, the main unit water tank 210 specifically includes a water tank body 211, a float 212, and a hollow guide column 213 with a float guide channel (not shown in the figure). A top water inlet 24 and a top vent 25 are respectively provided through the top side of the water tank body 211. The top water inlet 24 is connected to the main unit water inlet 21 (specifically, the connection between the two can be achieved through a second connecting pipe 230). The hollow guide column 213 is installed inside the water tank body 211, and the top end of the float guide channel 212 is connected to the top vent 25. The bottom end of the float guide channel is located near the bottom side of the water tank body 211 and is connected to the internal space of the water tank body 211. The float 212 is limited and positioned within the float guide channel. Thus, with the above structural arrangement, when the main unit water tank 210 receives clean water from the main unit water inlet 21, the float 212 begins to rise with the water level. When the water tank body 211... Figure 10 When the water is full, the float 212 reaches its highest point and blocks the top vent 25. The water tank body 211 can no longer expel gas, so water cannot continue to be injected. The base station water inlet 11 can no longer send water to the host water inlet 21. It can only continue to be stored in the buffer water chamber 141 until the water blocking effect is triggered in the buffer water chamber 141. The base station water tank 110 can no longer dispense water, and then the entire automatic water injection system 1 stops working.
