All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application. The various embodiments described below and their technical features can be combined with each other without conflict.

After the cleaning host machine runs for a period of time, the cleaning host machine needs to return to the cleaning base station to automatically replenish water for the host machine water tank in the cleaning host machine through the base station water tank in the cleaning base station, and the base station water tank generally only controls the water injection assembly to be opened to perform water replenishing operation for the host machine water tank after the cleaning host machine returns to the cleaning base station, so that the water leakage problem caused by the opening of the water injection assembly when the cleaning host machine is not in time is avoided, and the process is mainly completed through an automatic water injection system. The automatic water injection system in the existing market mainly detects whether the cleaning host machine returns to the cleaning base station through an electronic detection mode of the charging pole piece, so that after the cleaning host machine returns to the cleaning base station, the water injection assembly is controlled to be opened to carry out water supplementing operation on a host machine water tank. However, in the practical use process, it is found that the electronic detection mode through the charging pole piece can cause deviation in the butt joint of the water injection assembly under the condition that the charging pole piece is a module relatively independent of the water injection assembly, once the butt joint of the water injection assembly is deviated, the problems of water injection and water leakage and the like can occur, the normal work of the cleaning base station and the cleaning host machine is affected, meanwhile, the electronic detection mode can also cause detection failure problems once the electronic components fail due to the use of the electronic components, and therefore, the electronic detection mode is easy to bring the problem of unreliable detection.

Based on this, it is necessary to provide a new technical solution of the automatic water injection system, so as to effectively improve the technical problem that the existing automatic water injection system adopts an electronic detection mode to confirm whether the cleaning host is assembled in place in the cleaning base station, which is easy to cause unreliable detection.

As shown in fig. 1 to 4, in one embodiment, the present application provides an automatic water injection system 1, where the automatic water injection system 1 may specifically include a cleaning base station 100 having a base station water tank 110 and a cleaning host 200 having a host water tank 210, where the cleaning base station 100 may specifically be provided with a host receiving slot 120 for receiving the cleaning host 210, a base station water injection assembly 130 is provided in the host receiving slot 120, and the base station water injection assembly 130 includes a base station water injection port 11 that is disposed in communication with the base station water tank 110 and a first spring sealing structure 131 for movably sealing the base station water injection port 11. The cleaning main machine 200 may be specifically provided with a main machine water injection assembly 220, where the main machine water injection assembly 220 includes a main machine water injection port 21 that is disposed in communication with the main machine water tank 210, and a second spring sealing structure 221 that movably plugs the main machine water injection port 21. The main unit water injection assembly 220 can be in plug-in fit with the base station water injection assembly 130 when the cleaning main unit 200 is assembled in place in the main unit accommodating groove 120, and respectively extrude the first spring sealing structure 131 and the second spring sealing structure 221 under the action force of the plug-in fit so as to open the corresponding base station water injection port 11 and the main unit water injection port 21, thereby realizing the automatic water injection operation of the base station water tank 110 to the main unit water tank 210.

It is to be understood that the automatic water injection system 1 of the embodiment of the present application is mainly applied to the automatic water replenishment operation of the cleaning main machine 200. The cleaning main body 200 may be a cleaning robot, which may automatically run into the main body receiving groove 120 of the cleaning base station 100. Since the bottom wall of the main unit receiving groove 120 is generally slightly higher than the ground, a slope 121 may be provided at the opening of the main unit receiving groove 120 to facilitate the automatic movement of the cleaning main unit 200 into the main unit receiving groove 120 through the slope 121. The installation position of the host water injection assembly 220 on the cleaning host 200 should be set corresponding to the installation position of the base station water injection assembly 120 in the host accommodating groove 120, so that when the cleaning host 200 is assembled in place in the host accommodating groove 120, the host water injection assembly 220 just faces to the plugging fit with the base station water injection assembly 120, therefore, preferably, the host water injection assembly 220 should be arranged on the outer side wall of the cleaning host 200, and the base station water injection assembly 120 should be arranged on the inner side wall of the host accommodating groove 120, so that when the cleaning host 200 is assembled in place in the host accommodating groove 120 in a lateral plugging fit manner, the host water injection assembly 220 can be fast and the base station water injection assembly 120 just face to the plugging fit, and at the moment, under the action force of the plugging fit, the first spring sealing structure 131 and the second spring sealing structure 221 are respectively extruded to open the corresponding base station water injection port 11 and the host water injection port 21, so that the host water injection assembly 220 is communicated with the base station water injection assembly 120, and further automatic water injection operation of the base station water tank 110 on the host water tank 210 is realized.

In this way, according to the technical scheme of the embodiment of the present application, the base station water tank 110 is ensured to be automatically filled with water only when the cleaning host 200 is assembled in place in the host accommodating groove 120 in a mechanical structure manner, so that the unreliable problem caused by the existing electronic detection manner can be effectively avoided.

In some examples, as shown in fig. 2, 3 and 4, the base station water injection assembly 130 specifically further includes a base station water injection housing 132 having the base station water injection channel 12 built therein. The base station water injection shell 132 further has a plug part 13 which can be plugged and matched with the host water injection assembly 220, and a base station water injection port 11 which is communicated with the base station water injection channel 12 is formed in the end face of the plug part 13. One end of the base station water injection channel 12, which is far away from the base station water injection port 11, is communicated with the base station water tank 110, so that the base station water injection port 11 is communicated with 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 block the base station water injection port 11. In this way, through the above structure, the water in the base station water tank 110 can reach the vicinity of the base station water filling port 11 through the base station water filling channel 12, and when the first spring sealing structure 131 is not acted by external force, it can be abutted against and blocked by the base station water filling port 11 under the elastic acting force of itself, so that the water in the base station water filling channel 12 can not flow out through the base station water filling port 11, and when the first spring sealing structure 131 is acted by external force, and the external force is greater than the elastic acting force of itself, it can be far away from the base station water filling port 11, so that the base station water filling port 11 is opened, and at this time, the water in the base station water filling channel 12 can flow out through the base station water filling port 11.

In some examples, as shown in fig. 2, 3 and 4, the first spring sealing structure 131 may specifically include a first rubber plug 1311 and a first spring 1312, where one end of the first rubber plug 1311 is elastically assembled in the base station water injection channel 12 through the first spring 1312, so that the base station water injection port 11 is blocked by the other end of the first rubber plug 1311 under the elastic force of the first spring 1312. Further, the first spring sealing structure 131 further comprises a spring cover 1313 provided with a water permeable hole, and the spring cover 1313 is arranged at one end of the base station water injection channel 12 far away from the base station water injection port 11; the first rubber plug 1311 comprises an abutting portion 13111 and a connecting portion 13112 which are arranged in a connected mode, wherein the radial sectional area of the abutting portion 13111 is larger than the radial area of the connecting portion 13112, so that a step abutting surface is formed at the joint between the abutting portion 13111 and the connecting portion 13112; the connecting portion 13112 is sleeved with the first spring 1312, and one end of the connecting portion 13112 away from the abutting portion 13111 is disposed through the spring cover 1313, so that one end of the first spring 1312 abuts against the spring cover 1313, and the other end of the first spring 1312 abuts against the step abutting surface, so that under elastic force of the first spring 1312, one end of the abutting portion 13111 away from the connecting portion 13112 abuts against the base station water filling port 11.

It can be appreciated that the base station water injection housing 132 may be configured in an integral structure, or may be configured in a split structure as shown in fig. 4, so as to facilitate the assembly of the first spring sealing structure 131, at this time, the base station water injection housing 132 may specifically include a base station water injection front housing 1321 and a base station water injection rear housing 1322, which are assembled together through a snap-fit connection, so as to form the base station water injection channel 12 through surrounding, and in order to ensure the sealing performance of the connection between the two, a sealing ring 1323 is further provided at the connection part between the two. In addition, the plugging portion 13 may be specifically disposed on the base station water injection front housing 1321 in a protruding manner, and the outer peripheral side of the plugging portion 13 may be sleeved with the soft rubber portion 14, so that the plugging portion 13 may be more tightly plugged with the host water injection assembly 220.

In some examples, as shown in fig. 2, 5, and 6, the host water injection assembly 220 further includes a host water injection housing 222 having the host water injection channel 22 built-in. The main unit water injection housing 222 has a plug groove 23 which can be plug-fitted with the plug portion 13, and a main unit water injection port 21 which is communicated with the main unit water injection channel 22 is provided at the bottom wall of the plug groove 23. One end of the main machine water filling channel 22, which is far away from the main machine water filling port 21, is communicated with the main machine water tank 210, so that the main machine water filling port 21 is communicated with the main machine water tank 210 through the main machine water filling channel. The second spring sealing structure 221 is elastically assembled in the host water injection channel 22 to movably plug the host water injection port 21, and when the plug groove 23 is in plug fit with the plug part 13, the second spring sealing structure 221 can be pressed by the plug part 13 in a butt joint manner, so that the second spring sealing structure 221 can movably open the host water injection port 21. Therefore, through the above structure, when the second spring sealing structure 221 is not acted by an external force, it can be abutted against and blocked by the host water injection port 21 under the elastic force of itself, and the external water cannot flow into the host water injection channel 22 through the host water injection port 21, and when the second spring sealing structure 221 is acted by an external force, and the external force is greater than the elastic force of itself, it is far away from the host water injection port 21, so that the host water injection port 21 is opened, at this time, the external water can flow into the host water injection channel 12 through the host water injection port 21 and flow into the host water tank 210 through the host water injection channel 12.

In some examples, as shown in fig. 2, 5 and 6, the second spring sealing structure 221 may specifically include a second rubber plug 2211 and a second spring 2212, where one end of the second rubber plug 2211 is elastically assembled in the host water injection channel 22 through the second spring 2212, so as to block the host water injection port 21 through the other end of the second rubber plug 2211 under the elastic force of the second spring 2212. Further, a plug thimble 2213 in plug-in fit with the base station water filling port 11 is protruding from an end surface of the second plug 2211 facing the host water filling port 21, so that when the plug groove 23 is in plug-in fit with the plug portion 13, the plug thimble 2213 is inserted into the base station water filling port 11 and presses the first spring sealing structure 131 through abutting connection, so that the first spring sealing structure 131 movably opens the base station water filling port 11.

It can be appreciated that the host water injection housing 222 may be configured as an integral structure, or may be configured as a split structure as shown in fig. 6, so as to facilitate the assembly of the second spring sealing structure 221, at this time, the host water injection housing 222 may specifically include a host water injection front housing 2221 and a host water injection rear housing 2222, which are assembled together through a snap-fit connection to form the host water injection channel 22 through surrounding. In addition, the plugging slot 23 may be specifically protruding on the front shell 2221 of the main unit for water injection.

In some examples, as shown in fig. 1 to 6, the main unit water injection assembly 220 may be further configured such that, when the cleaning main unit 200 is assembled in place in the main unit receiving slot 120, the main unit water injection assembly 220 is in plug-in fit with the base station water injection assembly 130, and the second spring sealing structure 221 and the first spring sealing structure 131 are sequentially pressed under the acting force of the plug-in fit, so as to sequentially open the corresponding main unit water injection port 21 and the base station water injection port 11, thereby implementing the automatic water injection operation of the base station water tank 110 on the main unit water tank 210. In this way, through the above structural design, only if the main machine water injection assembly 220 and the base station water injection assembly 130 are completely inserted and matched in place, it is judged that the cleaning main machine 200 is assembled in place in the main machine accommodating groove 120, the second spring sealing structure 221 and the first spring sealing structure 131 can be sequentially pressed under the action force of the insertion and matching, so that the corresponding main machine water injection port 21 and the base station water injection port 11 are sequentially opened, the automatic water injection operation of the base station water tank 110 on the main machine water tank 210 is realized, if only the main machine water injection assembly 220 and the base station water injection assembly 130 are inserted and matched in place, the situation that only the second spring sealing structure 221 is pressed, the main machine water injection port 21 is opened, the first spring sealing structure 131 is not pressed, the base station water injection port 11 is not opened, the base station water tank 110 cannot perform the automatic water injection operation on the main machine water tank 210, the situation that the base station water tank 110 is not assembled in place in the main machine accommodating groove 120 at present is met, and meanwhile, the base station water injection port 11 is not opened, and the problem of water leakage can be avoided. Therefore, the accuracy of the judgment of whether the cleaning main body 200 is fitted in place in the main body receiving groove 120 can be further improved by the above-described structural design. Further, the elastic force of the second spring 2212 can be designed to be smaller than that of the first spring 1312, and the elastic force of the first spring 1312 is smaller than the retreating force of the cleaning main machine 200, so that the sequence of pushing up the rubber plugs is that the second rubber plug 2211 is pushed up first and then the first rubber plug 1311 is pushed up. When the cleaning host 200 exits the cleaning base station 100, the first rubber plug 1311 is closed first, and the second rubber plug 2211 is closed later, so that water leakage of the base station water filling port 11 is avoided when the cleaning host 200 exits the cleaning base station 100. If the docking position of the cleaning host 200 is not right, the host water filling port 21 is not aligned with the base station water filling port 11 or is not completely in place, the first rubber plug 1311 is not pushed open, the base station water filling port 11 is in a sealed state, water cannot be filled, and water filling and water leakage cannot occur.

In some examples, as shown in fig. 2, 7 and 8, the cleaning base station 100 further includes a water blocking tank support 140 having a buffer water chamber 141, the base station water tank 110 is mounted and fixed on the water blocking tank support 140, and the buffer water chamber 141 is located directly below the bottom water outlet 111 of the base station water tank 140. The buffer water chamber 141 is communicated with the bottom water outlet 111, and the buffer water chamber 141 is also communicated with the base station water filling port 11, so that the base station water filling port 11 is communicated with the base station water tank 110 through the buffer water chamber 141. Further, an elastic rubber plug structure 112 is installed on one side of the bottom water outlet 111 far away from the water buffering chamber 141, so as to movably block the bottom water outlet 111. Still further, a base station water-blocking seat 142 is further installed on the water-blocking box support 140, the base station water-blocking seat 142 is located in the water-buffering chamber 141, and when the base station water tank 110 is installed and fixed on the water-blocking box support 140, the base station water-blocking seat 142 is abutted to the elastic rubber plug structure 112, so that the elastic rubber plug structure 112 can movably open the bottom water outlet 111.

It can be appreciated that the top water filling port of the base station water tank 110 is designed with a sealing rubber plug for movably plugging the top water filling port, so that the daily water filling operation of the base station water tank 110 is facilitated, and the bottom water outlet 111 of the base station water tank 110 is provided with an elastic rubber plug structure 112 for sealing, so that the base station water tank 110 maintains a sealing state when lifted up, and the base station water tank is propped up by the base station water blocking seat 142 to open water when assembled with the water blocking tank bracket 140. The buffer water chamber 141 may be provided with a water outlet at the bottom side, and the water outlet may be communicated with the water filling port 11 of the base station through the first connecting pipe 150

In some examples, as shown in fig. 2, 7 and 8, the base station water-blocking seat 142 may specifically include a water-blocking seat body 1421 and a hollow water-blocking column 1422 having a drainage channel (not labeled in the figures). One side of the water-blocking seat 1421 facing the bottom water outlet 111 is provided with a containing groove 14211, a plurality of through holes 14212 are formed in the side wall of the containing groove 14211 in a penetrating manner, and a drain hole (not labeled in the figure) is formed in the bottom wall of the containing groove 14211 in a penetrating manner. One end of the hollow water blocking column 1422 is fixedly arranged on the bottom wall of the accommodating groove 14211, and one end of the drainage channel is communicated with the drainage hole. The other end of the hollow water blocking cylinder 1422 is provided with a water inlet hole (not labeled in the figure) which is communicated with the water drainage channel, and the other end of the hollow water blocking cylinder 1422 can be inserted into the bottom water outlet 111 and abutted against the elastic rubber plug structure 112 when the base station water tank 110 is fixedly arranged on the water blocking tank bracket 140, so that the elastic rubber plug structure 112 can movably open the bottom water outlet 111. In this way, by the above arrangement, a drain line shown by a solid arrow in fig. 7, that is, an intake line shown by a broken arrow can be formed. When the base station water tank 110 is placed into the water blocking tank bracket 140, the elastic rubber plug structure 112 on the bottom water outlet 111 is pushed open by the base station water blocking seat 142 to start leaking water into the buffer water chamber 141, when the cleaning base station 100 is not docked with the cleaning host 200, the base station water filling port 11 is sealed, water cannot continue to flow out and can only be stored in the buffer water chamber 141, the water level in the buffer water chamber 141 can rise, after rising to a certain extent, the water level can seal an air inlet line shown by a dotted arrow in fig. 7, at this time, because the base station water tank 110 cannot obtain supplementary air from the outside, the base station water tank 110 can not discharge water (one atmosphere pressure can support 10.13M water columns according to the atmospheric pressure theorem, and the water tank design can completely meet the requirements of people). After the cleaning base station 100 is docked with the cleaning host 200, water in the buffer water chamber 141 flows into the base station water filling port 11 via the first connecting pipe 150 and then flows into the host water filling port 21, and finally flows into the host water tank 210, so that the water level in the buffer water chamber 141 begins to drop, the air inlet line is exposed again, and the base station water tank 110 can continue to leak water into the buffer water chamber 141, so that clean water with a certain water level in the buffer water chamber 141 is always stored.

In addition, in the above example, by matching the water-blocking seat 142 with the structural design of the water-buffering chamber 141, the water of the base station water tank 110 is buffered to the water-buffering chamber 141, and then flows to the base station water-filling port 11 automatically under the action of gravity via the water-buffering chamber 141, because the water in the water-buffering chamber 141 is far less than the water in the base station water tank 110, the water pressure flowing from the water-buffering chamber 14 to the base station water-filling port 11 is far less than the water pressure flowing from the base station water tank 110 to the base station water-filling port 11 directly, so by matching the water-blocking seat 142 with the structural design of the water-buffering chamber 141, the base station water-filling port 11 can be ensured to perform uniform water outlet smoothly in the water-filling operation process.

In some examples, as shown in fig. 2, 9 and 10, the main tank 210 may include a tank body 211, a float 212, and a hollow guide cylinder 213 having a float guide channel (not shown). The top side of the water tank main body 211 is respectively provided with a top water inlet 24 and a top air outlet 25 in a penetrating way, the top water inlet 24 is communicated with the host water filling port 21 (specifically, the communication between the two can be realized through a second connecting pipe 230), the hollow guide column body 213 is arranged on the inner side of the water tank main body 211, the top end of the floating ball guide channel 212 is communicated with the top air outlet 25, the bottom end of the floating ball guide channel is adjacent to the bottom side of the water tank main body 211, and the bottom end of the floating ball guide channel is communicated with the inner space of the water tank main body 211. The floating ball 212 is limited and arranged in the floating ball guide channel. In this way, through the above-mentioned structure, when the main water tank 210 receives the clean water from the main water filling port 21, the floating ball 212 starts to rise along with the water surface, and when the water tank main body 211 is filled with water as shown in fig. 10, the floating ball 212 reaches the highest point and blocks the top air outlet 25, the water tank main body 211 cannot discharge air, the water cannot be continuously filled, the base station water filling port 11 cannot continuously feed water to the main water filling port 21, only the water can be continuously stored in the buffer water chamber 141 until the buffer water chamber 141 triggers the water blocking effect, the base station water tank 110 cannot continuously discharge water, and the whole automatic water filling system 1 stops working.
