Description

Technical Field

[0001] This utility model belongs to the field of ground cleaning technology, and in particular relates to a sewage tank component and cleaning equipment. Background Technology

[0002] Cleaning products with wastewater recycling systems on the market generally have sensors installed inside the wastewater tank to detect whether the wastewater level in the tank has reached a predetermined height.

[0003] Chinese patent application CN117678936A discloses a wastewater tank for a cleaning device, which includes a first liquid level detection element, a second liquid level detection element, and a third liquid level detection element. The first and second liquid level detection elements work together to detect the liquid level in the wastewater separation chamber, and the first and third liquid level detection elements work together to detect the liquid level in the solid-liquid separation chamber. However, because the first liquid level detection element is fixed to the bottom of the wastewater receiving chamber, its surface easily accumulates dirt, making cleaning within the chamber difficult. Furthermore, each detection requires the first liquid level detection element; if it malfunctions, neither the wastewater separation chamber nor the solid-liquid separation chamber can be detected.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0063] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0064] This application provides a wastewater tank assembly 1 for use in a cleaning device, which includes a suction motor 21. Figures 1 to 3 As shown, the sewage tank assembly 1 in this embodiment includes at least a water tank 10 and a water-filled assembly 12 detachably disposed within the water tank 10.

[0065] The water tank 10 has a suction pipe 100 and a sewage chamber inside, and the sewage 4 outside can enter the sewage chamber through the suction pipe 100 for storage.

[0066] The suction motor 21 on the cleaning equipment can be connected to the sewage tank assembly 1. Activating the suction motor 21 can draw the water tank 10 out of the negative pressure state. At this time, under the action of negative pressure, the external sewage 4 can flow into the sewage chamber through the suction pipe 100.

[0067] The water filling assembly 12 includes at least two detection elements. Each of the two detection elements is equipped with a first probe (not shown in the figure) and a second probe (not shown in the figure), and the two first probes and the two second probes are electrically connected to the suction motor 21.

[0068] During the tilting process of water tank 10, the sewage 4 in the sewage chamber can overflow the two first probes, causing the two first probes to conduct and generate a first full water signal. Figure 6 As shown. The tilted state can be understood as the angle between the vertical axis of the water tank 10 and the ground being within a first angular range.

[0069] While the water tank 10 is in a horizontal position, the sewage 4 in the sewage chamber can overflow the two second probes, causing them to conduct and generate a second full-water signal. Figure 7As shown. The "flat" position is understood as the angle between the vertical axis of the water tank 10 and the ground falling within the second angular range.

[0070] The cleaning equipment can receive the first water full signal and the second water full signal respectively to stop the operation of the suction motor 21.

[0071] The water-filling component 12 of the wastewater tank assembly 1 provided in this application can be integrated as a whole and detachably installed inside the water tank 10. When cleaning the wastewater tank, both first and second probes can be removed from the water tank 10 together for easy cleaning and maintenance. Furthermore, since the two first probes and two second probes are used to detect whether the wastewater 4 is full when the water tank 10 is in different states, the use of the first and second probes does not affect each other. Even if one probe malfunctions, it does not affect the use of the other probe.

[0072] like Figures 2 to 3 As shown, the top of the water tank 10 can be open, and the water full assembly 12 can also include a water full bracket 120. Two detection components are fixed on the water full bracket 120 respectively. The water full bracket 120 is used to cover the open end of the top of the water tank 10.

[0073] A suction port 1207 can be installed on the water-filled bracket 120. When the wastewater tank assembly 1 is connected to the suction motor 21, the suction port 1207 on the water-filled bracket 120 can be opposite to the air inlet of the suction motor 21. When the suction motor 21 is started, the water vapor in the water tank 10 can be extracted through the suction port 1207.

[0074] In some embodiments, the water-filled bracket 120 can be detachably connected to the water tank 10. For example, the water-filled bracket 120 can be snapped onto the top open end of the water tank 10 as a whole, and the outer peripheral wall of the water-filled bracket 120 has a first adhesive coating 1203 that contacts the inner wall of the water tank 10. Before cleaning the entire device, the entire water-filled assembly 12 can be removed from the water tank 10, thereby facilitating the cleaning of the entire water tank 10 and the water-filled assembly 12.

[0075] In some embodiments, a filter 11 can be connected to the water tank 120. The filter 11 can cover the air intake 1207. When the suction motor 21 is started, the water vapor in the water tank 10 can be filtered through the filter 11 and then extracted by the suction motor 21. The filter 11 can be used to filter impurities from the discharged water vapor, thereby avoiding affecting the use of the suction motor 21.

[0076] like Figure 2 , Figure 6 and Figure 7As shown, in some embodiments, the water-filled support 120 may include a first support 1201 and a second support 1202 located on opposite sides of the suction pipe 100. The first support 1201 and the second support 1202 may extend toward the bottom of the water tank 10, respectively.

[0077] One of the two sensing elements is located on the first support 1201, and the other sensing element is located on the second support 1202.

[0078] The two sensing plates each have a first plate 1211 extending toward the bottom of the water tank 10 and a second plate 1212 extending toward the side wall of the water tank 10.

[0079] The first support plate 1211 is closer to the bottom of the water tank 10 than the second support plate 1212. The second support plate 1212 is closer to the side wall of the water tank 10 than the first support plate 1211.

[0080] The first probe on the two sensing plates can be located on the first support plate 1211, and the second probe on the two sensing plates can be located on the second support plate 1212.

[0081] See Figure 6 As shown, when the water tank 10 is tilted, as the sewage 4 continuously flows into the sewage chamber, the sewage 4 rises continuously. The sewage 4 will first overflow the two first probes. At this time, the two first probes will conduct to generate the first water full signal. After receiving the first water full signal, the cleaning equipment will stop the running suction motor 21.

[0082] See Figure 7 As shown, when the water tank 10 is in a horizontal position, the sewage 4 no longer submerges the two first probes. However, as the amount of sewage 4 gradually increases, it will gradually overflow the two second probes, causing them to conduct and generate a second full water signal. After receiving the second full water signal, the cleaning equipment will stop the running suction motor 21.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, the wastewater tank assembly 1 may further include a solid-liquid separation frame 13 located within the water tank 10, the solid-liquid separation frame 13 being connected to the water-filled support 120. That is, the solid-liquid separation frame 13 and the water-filled assembly 120 can form an integral unit, see... Figure 4 and Figure 5 As shown, this allows for a detachable connection with the water tank 10.

[0084] The solid-liquid separator 13 divides the wastewater chamber within the water tank 10 into a first chamber 101 and a second chamber 102. The first chamber 101 and the second chamber 102 are respectively arranged around the suction pipe 100. The first chamber 101 is located at the bottom of the water tank 10, and the second chamber 102 is located above the first chamber 101. When the water tank 10 is tilted, the wastewater 4 entering the water tank 10 through the suction pipe 100 will first flow downwards into the first chamber 101.

[0085] The water-filled support 120 is provided with a first baffle 1204, which is used to divide the second cavity 102 into a third cavity 103 and a fourth cavity 104.

[0086] The solid-liquid separator 13 has a separation hole 131 that connects the first cavity 101 and the third cavity 103. During the process of the water tank 10 changing from an inclined state to a flat state, the sewage 4 in the first cavity 101 can flow into the third cavity 103 through the separation hole 131 of the solid-liquid separator 13.

[0087] In some embodiments, the first support plate 1211 of the two sensing plates can extend into the first cavity 101 so that the sewage 4 flowing into the first cavity 101 can overflow the first probe fixed on the first support plate 1211.

[0088] The second support plate 1212 can extend into the third cavity 103, and the second support plate 1212 can be opposite to the side wall of the water tank 10.

[0089] In some embodiments, the solid-liquid separation frame 13 has a flat portion 132 and an inclined portion 133 on the side opposite to the first cavity 101. The inclined portion 133 is opposite to the fourth cavity 104 and has a guide rib 134. The inclined portion 133 is inclined toward the fourth cavity 104.

[0090] Furthermore, the separation hole 131 on the solid-liquid separator extends to the flat portion 132, while no separation hole 131 is provided on the inclined portion 133. In addition, a second adhesive coating 130 is provided on the outer peripheral wall of the portion of the fixed separation frame where the inclined portion 133 is located, which is in contact with the inner wall of the water tank 10.

[0091] Thus, when the water tank 10 is shaken during use, the sewage 4 in the sewage chamber may generate water waves, which may be sucked into the air intake 1207 along the side wall of the water tank 10. At this time, a buffer area is formed between the inclined surface 133 on the solid-liquid separation frame 13, the second rubber coating 130, and the inner wall of the water tank 10, thereby blocking the water waves. Then, the water waves can be dispersed by the guide rib 134, and the sewage 4 splashed on the guide rib 134 can flow back down along the guide rib 134, thereby preventing the sewage 4 from entering the air intake 1207.

[0092] like Figure 4 and Figure 8 As shown, in some embodiments, the air intake 1207 on the water-filled bracket 120 may be located between the first bracket 1201 and the second bracket 1202, and the water-filled bracket 120 may have a partition wall 1208 extending from the air intake 1207 into the fourth cavity 104.

[0093] The partition wall 1208 can be close to the wall of the suction pipe 100, and the shape of the partition wall 1208 can be adapted to the wall of the suction pipe 100. There is an airflow channel 1217 between the partition wall 1208 and the wall of the suction pipe 100. When the water tank 10 is in a flat position and the suction motor 21 is started, some of the water vapor in the suction pipe 100 enters the water tank 10 and can be directly sucked into the air intake 1207 through the airflow channel 1217. The remaining water vapor in the water tank 10 can be sucked into the air intake 1207 through the gap between the suction pipe 100 and the two connecting brackets 135.

[0094] The air intake 1207 on the water-filled bracket 120 is kept a considerable distance from the inner wall of the water tank 10, which prevents splashing water droplets from climbing up the inner wall of the water tank 10. The greater distance between the air intake 1207 and the inner wall of the water tank 10 reduces the attraction of water droplets to the inner wall of the wastewater tank. A partition wall 1208 separates the air intake 1207 from the suction pipe 100 to prevent wastewater 4 from directly entering the air intake 1207.

[0095] The end of the partition wall 1208 connected to the air intake 1207 has a first baffle 1209. The first baffle 1209 extends along the radial direction of the air intake 1207 and at least blocks part of the air intake 1207. The function of the first baffle 1209 is to lift the air intake 1207 on the water-filled bracket 120, so as to prevent water droplets dripping on the partition wall 1208 from being sucked into the air intake 1207.

[0096] The partition wall 1208 has a second baffle 1210 at the end opposite to the air intake 1207. The second baffle 1210 is inclined in a direction away from the suction pipe 100, so that when the water tank 10 is placed vertically, the water droplets dripping on the partition wall 1208 can drip down along the second baffle 1210 into the first cavity 101.

[0097] like Figure 2 As shown, in some embodiments, a first slot 1213 for placing the first probe may be provided on the first support plate 1211, and the first slot 1213 may extend to the side wall of the first support plate 1211. The solid-liquid separation frame 13 may have a connecting frame 135 connected to the two supports. When the connecting frame 135 is connected to the first support 1201 and the second support 1202, the connecting frame 135 can cover the first slot 1213, thereby preventing sewage 4 from splashing onto the first probe.

[0098] The connecting frame 135 on the solid-liquid separation frame 13 may have a vent hole 137 in the area opposite to the first slot 1213 on the first support plate 1211. When sewage 4 enters the first slot 1213, the sewage 4 can also be discharged through the vent hole 137, so as to avoid the sewage 4 accumulating in the first slot 1213 and being difficult to discharge.

[0099] The second support plate 1212 has a second slot 1214 for placing the second probe and an isolation rib 1215 surrounding the second slot 1214.

[0100] The isolation rib 1215 can protrude from the second slot 1214, and the isolation rib 1215 can completely cover the entire second slot 1214 or partially cover the second slot 1214. In this way, the isolation rib 1215 can prevent sewage 4 from splashing onto the second probe.

[0101] like Figure 2 As shown, in some embodiments, a fixing post 1216 can be respectively provided on the first bracket 1201 and the second bracket 1202, and a fixing hole 136 corresponding to the fixing post 1216 can be provided on the connecting bracket 135. A bolt hole can be provided on the fixing post 1216, and the fixing hole 136 and the fixing post 1216 can be connected by bolts, thereby fixing the solid-liquid separation frame 13 on the water-filled bracket 120.

[0102] like Figure 4 As shown, in some embodiments, the edge of the first baffle 1204 can fit against the inner wall of the water tank 10, which can prevent the sewage 4 in the third cavity 103 from being sucked into the fourth cavity 104 along the side wall of the water tank 10 when the suction motor 21 is drawing air.

[0103] Furthermore, the water-filled support 120 may also include a second retaining wall 1205 and a third retaining wall 1206 located on both sides of the partition wall 1208. The number of the second retaining wall 1205 and the third retaining wall 1206 located on one side of the partition wall 1208 may be one or two, etc.

[0104] The extension directions of the second baffle 1205 and the third baffle 1206 can be consistent with the extension direction of the partition 1208. The edges of the second baffle 1205 and the third baffle 1206 can be attached to or not attached to the inner wall of the water tank 10. Due to the suction, sewage 4 will rise along the first baffle 1204. The second baffle 1205 and the third baffle 1206 can block this sewage 4, thereby preventing it from being sucked into the air intake 1207.

[0105] In some embodiments, the second retaining wall 1205 may be closer to the first retaining wall 1204 than the third retaining wall 1206. That is, the second retaining wall 1205 may be located on the side of the third retaining wall 1206 facing away from the partition wall 1208. The length of the second retaining wall 1205 in its extending direction may be greater than the length of the third retaining wall 1206 in its extending direction, but less than the length of the first retaining wall 1204 in its extending direction.

[0106] like Figure 9 and Figure 10 As shown in the figure, this application embodiment also provides a cleaning device, which may include a mop assembly 3, a main unit assembly 2, a body assembly 5, and a wastewater tank assembly 1 as described in any of the above embodiments.

[0107] The mop assembly 3 can be connected to the body assembly 5, and the wastewater tank assembly 1 and the main unit assembly 2 can be respectively installed on the body assembly 5.

[0108] The main unit 2 can be connected to the sewage tank assembly 1, and the suction pipe 100 on the sewage tank assembly 1 can be connected to the sewage inlet channel on the mop assembly 3.

[0109] The main unit 2 may include at least a suction motor 21, which can be connected to the wastewater tank assembly 1. The air inlet of the suction motor 21 can be opposite to the filter 11 on the wastewater tank assembly 1. When the suction motor 21 is started, the water vapor in the water tank 10 can be filtered by the filter 11 and then sucked out. At this time, the water tank 10 is under negative pressure. When the mop assembly 3 cleans the floor, the wastewater 4 on the floor can be sucked into the water tank 10 through the wastewater inlet channel and the suction pipe 100, thereby realizing the collection of wastewater 4.

[0110] In some embodiments, the body assembly 5 can be rotatably connected to the mop assembly 3. When cleaning the floor, the user can rotate the body assembly 5 to a tilted position so that the water tank 10 is also tilted. At this time, the user can hold the body assembly 5 to push the mop assembly 3 on the floor, thereby achieving floor cleaning. Figure 9 As shown.

[0111] When cleaning the space under furniture such as sofas or bookshelves, the main unit 5 can be rotated to a flat position. By holding the main unit 5, the mop unit 3 can be pushed to the space under the furniture, thus cleaning the floor. (See...) Figure 10 As shown.
