Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a sludge storage bin and cleaning equipment. Background Technology

[0002] With the continuous improvement of people's living standards, cleaning equipment such as vacuum cleaners and floor scrubbers have been widely used in homes, offices, and commercial environments. However, traditional vacuum cleaners and floor scrubbers often lack multi-angle and multi-position operation capabilities. Furthermore, in daily use, the dirt storage tanks of traditional cleaning equipment often lack omnidirectional liquid storage functionality. If accidentally tipped over, fallen, or used when cleaning walls, cabinets, or ceiling corners, the specific positioning of the cleaning equipment can cause wastewater leakage. Therefore, how to improve the dirt storage tank to achieve omnidirectional liquid storage, thereby enhancing the safety and omnidirectional cleaning performance of cleaning equipment, has become an urgent problem to be solved. Utility Model Content

[0003] In view of this, this application proposes a sludge storage tank and a cleaning device, which has omnidirectional liquid storage function and has the advantages of high sludge collection efficiency and good backflow prevention effect.

[0004] Firstly, this application proposes a wastewater storage bin, comprising:

[0005] A sewage tank, the sewage tank including a sewage storage chamber;

[0006] A negative pressure conduit is provided at the top of the sewage tank.

[0019] The second port of the wastewater collection pipe faces the bottom of the wastewater tank, and the second port of the negative pressure collection pipe faces the side wall of the wastewater tank.

[0020] In some embodiments, the wastewater tank includes a tank cover and a cavity, the negative pressure conduit and the wastewater receiving conduit are disposed on the tank cover, and the tank cover is detachably connected to the cavity to form a wastewater storage cavity.

[0021] In some embodiments, the cover is provided with a first closing portion, the cavity is provided with a second closing portion, the first closing portion and / or the second closing portion are provided with a first sealing element, and the first closing portion is sealed to the second closing portion through the first sealing element.

[0022] In some embodiments, the periphery of the first port of the negative pressure conducting tube is provided with an adapter surface.

[0023] In some embodiments, the sludge reservoir is further provided with a sensor, the sludge reservoir being connectable to a cleaning device, the sensor being used to enable a sensor disposed on the cleaning device to detect the tightness and / or sealing of the connection.

[0024] In some embodiments, the sludge storage tank further includes an engaging assembly disposed on the sludge tank body, the engaging assembly comprising:

[0025] A first locking component is disposed on the sewage tank body. The first locking component cooperates with a second locking component on the cleaning device to fix the sewage storage tank on the cleaning device in a first direction.

[0026] An active component is disposed on the wastewater tank body. The active component is movable relative to the wastewater tank body in a second direction and cooperates with the fixing groove of the cleaning equipment for fixing the wastewater tank to the cleaning equipment in the second direction, which is perpendicular to the first direction.

[0027] The movable component is movable relative to the wastewater tank in a second direction and can engage or disengage with the fixed slot of the cleaning equipment, thereby locking the wastewater tank to the cleaning equipment or unlocking the wastewater tank from the cleaning equipment.

[0028] In some embodiments, the movable component is disposed on the bottom outer side of the wastewater tank, and the movable component includes:

[0029] A gear, which is rotatably mounted on the sewage tank body;

[0034] Secondly, this application proposes a cleaning device that includes a sludge storage tank as described in any embodiment of this application.

[0035] The wastewater storage chamber proposed in this application includes: a wastewater storage body, a negative pressure conduit pipe, and a wastewater receiving conduit pipe. The wastewater storage body includes a wastewater storage cavity. The negative pressure conduit pipe is located at the top of the wastewater storage body, with its first port connected to an external negative pressure channel and its second port located in the middle area of ​​the wastewater storage cavity. The negative pressure conduit pipe is used to generate negative pressure within the wastewater storage cavity. The wastewater receiving conduit pipe is located at the top of the wastewater storage body, with its first port connected to an external wastewater receiving channel and its second port located in the middle area of ​​the wastewater storage cavity. The wastewater receiving conduit pipe is used to introduce waste liquid into the wastewater storage cavity. The area of ​​the wastewater storage cavity, excluding the middle area, can form an omnidirectional liquid storage space, which allows the wastewater storage chamber to store waste liquid in any orientation. The wastewater storage chamber proposed in this application, through the arrangement of a negative pressure conduit and a contaminant collection conduit, firstly creates an omnidirectional liquid storage space within the wastewater storage chamber, allowing the wastewater storage chamber to store wastewater in any orientation. Secondly, because the first port of the negative pressure conduit is connected to an external negative pressure channel, and the first port of the contaminant collection conduit is connected to an external contaminant collection channel, a negative pressure is created within the wastewater storage chamber. This accelerates the flow of wastewater from the contaminant collection conduit into the wastewater storage chamber, thereby improving the contaminant collection efficiency of the contaminant collection conduit. By applying the wastewater storage chamber proposed in this application, problems such as wastewater outflow and backflow caused by changes in the orientation of cleaning equipment can be improved, thereby enhancing the safety and omnidirectional cleaning performance of the cleaning equipment.

[0053] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0054] Please see Figures 1 to 5 ,like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in the figure, this application embodiment proposes a sludge storage tank, which may include a sewage tank body 10, a negative pressure conduit 20, and a sludge collection conduit 30. This sludge storage tank can be applied to cleaning equipment. Because the sludge storage tank has an omnidirectional liquid storage function and has advantages such as high sludge collection efficiency and good backflow prevention effect, the cleaning equipment can be used in any posture.

[0055] The wastewater tank 10 may include a wastewater storage chamber 11, which is used to hold waste liquid.

[0056] The negative pressure conduit 20 can be installed at the top 12 of the sewage tank 10. The first port 21 of the negative pressure conduit 20 can be connected to an external negative pressure channel, and the second port 22 of the negative pressure conduit 20 can be located in the middle area 111 of the sewage storage chamber 11. The negative pressure conduit 20 can be used to generate negative pressure in the sewage storage chamber 11. Specifically, the external negative pressure channel refers to the channel corresponding to the blower of the cleaning equipment. The blower operates through the external negative pressure channel and the negative pressure conduit 20, which can generate negative pressure in the sewage storage chamber 11.

[0057] The wastewater collection pipe 30 can be installed at the top 12 of the wastewater tank 10. The first port 31 of the wastewater collection pipe 30 can be connected to the external wastewater collection channel. The second port 32 of the wastewater collection pipe 30 can be located in the middle area 111 of the wastewater storage chamber 11. The wastewater collection pipe 30 can be used to introduce waste liquid into the wastewater storage chamber 11.

[0058] It is understandable that waste liquid can include liquids such as sewage, as well as solid pollutants such as hair clippings, paper scraps, and dust.

[0059] It is understandable that, since the negative pressure conduit 20 and the sludge-collecting conduit 30 only extend to the middle region 111 of the sludge storage chamber 11, the middle region 111 is the area located in the middle of the sludge storage chamber 11, and there is a certain distance between it and the side wall 14 of the sewage tank 10. The size of this distance can be set according to actual needs. The area of ​​the sludge storage chamber 11 other than the middle region 111 can form an omnidirectional liquid storage space 112, which allows the sludge storage tank to store waste liquid in any posture.

[0060] In some embodiments, the range corresponding to the intermediate region 111 can satisfy the following relationship:

[0061]

[0062] Wherein, d1 is the diameter or width of the sewage storage chamber 11 of the sewage tank 10, h1 is the height of the sewage storage chamber 11 of the sewage tank 10, d2 is the diameter or width of the middle region 111 of the sewage storage chamber 11, and h2 is the height of the middle region 111 of the sewage storage chamber 11.

[0063] Correspondingly, the middle area 111 can be defined by referring to the shapes of cubes, cylinders, or cuboids.

[0064] It is understandable that when the sludge storage cavity 11 is a square, d1 can be the width of the sludge storage cavity 11 of the sewage tank 10, and d2 can be the width of the middle area 111 of the sludge storage cavity 11. When the sludge storage cavity 11 is a cylinder or a sphere, d1 can be the diameter of the sludge storage cavity 11 of the sewage tank 10, and d2 can be the diameter of the middle area 111 of the sludge storage cavity 11.

[0065] For example, the second port 22 of the negative pressure conduit 20 and the second port 32 of the sludge conduit 30 are located at 1 / 6 to 5 / 6 of the distance from one side of the inner wall to the other side of the sewage tank 10.

[0066] For example, the second port 22 of the negative pressure conduit 20 and the second port 32 of the sludge conduit 30 are located at 1 / 6 to 5 / 6 of the distance from the top 12 to the bottom 13 of the sludge tank 10.

[0067] It is understandable that there can be a distance between the second port 22 of the negative pressure guide pipe 20 and the second port 32 of the sewage guide pipe 30 and the inner wall of the sewage tank 10, so that the maximum liquid storage depth of the omnidirectional liquid storage space 112 reaches 1.2-25.5 cm, ensuring omnidirectional liquid storage capacity.

[0068] For example, the shortest distance between the second port 22 of the negative pressure conduit 20 and the second port 32 of the sludge conduit 30 and the inner wall of the sludge tank 10 can be 1.2-25.5 cm, so that the maximum liquid storage depth of the omnidirectional liquid storage space 112 can reach 1.2-25.5 cm.

[0069] It is understandable that by limiting the distance from the second port 22 of the negative pressure guide pipe 20 and the second port 32 of the sludge-collecting guide pipe 30 to the inner wall of the sewage tank 10, or by limiting the range of the intermediate area 111, the maximum liquid storage depth of the omnidirectional liquid storage space 112 can be ensured on the basis that the omnidirectional liquid storage function of the sludge storage tank can be realized, thus ensuring the endurance and performance of the cleaning equipment, reducing the frequency of users disassembling and cleaning the sludge storage tank, and improving the product user experience.

[0070] In some embodiments, the first port 21 of the negative pressure conduit 20 may be opened in the middle part of the top 12 of the sewage tank 10, and the first port 31 of the sewage conduit 30 may be opened in the periphery of the top 12 of the sewage tank 10.

[0071] Understandably, since traditional gas-liquid separation devices often use centrifugal separation technology, wastewater may be thrown to the inner periphery of the wastewater separation chamber 10, while gas may flow out from the middle, creating negative pressure.

[0072] It can be further understood that, in order to better integrate the sludge storage tank with the traditional gas-liquid separation device, the first port 21 of the negative pressure guide pipe 20 can be opened in the middle of the top 12 of the sewage tank body 10, and the first port 31 of the sludge collection guide pipe 30 can be opened at the periphery of the top 12 of the sewage tank body 10. This not only reduces the flow guiding structure of the sludge storage tank and the sewage separation tank body 10, making the structure more compact, but also improves the separation and sludge collection effects of the cleaning equipment.

[0073] In some embodiments, the pipe portion of the wastewater conduit 30 may include a first pipe section 33 and a second pipe section 34 connected between two pipe openings. At least a portion of the first pipe section 33 may extend from the periphery of the top 12 of the wastewater tank 10 to the negative pressure conduit 20, and at least a portion of the second pipe section 34 may extend along the negative pressure conduit 20 to the central region 111.

[0074] It is understandable that by dividing the sewage conduit 30 into a first section 33 extending from the periphery of the top 12 of the sewage tank 10 to the negative pressure conduit 20 and a second section 34 extending along the negative pressure conduit 20 to the middle area 111, firstly, it is convenient to control the flow direction of the waste liquid and prevent the waste liquid from flying directly to the second port 22 of the negative pressure conduit 20, causing backflow and reducing efficiency; secondly, it enables the waste liquid to flow quickly into the middle area 111 and reach the sewage storage chamber 11; and thirdly, it can retain a larger omnidirectional liquid storage space 112 in the sewage storage chamber 11, ensuring the performance of the sewage storage tank and cleaning equipment.

[0075] In some embodiments, the sidewall of the second port 22 of the negative pressure conduit 20 near the contaminated conduit 30 protrudes from the second port 22 of the negative pressure conduit 20.

[0076] For example, the periphery of the second port 22 of the negative pressure conduction tube 20 may include a first sidewall 221 and a second sidewall 222, wherein the first sidewall 221 may be longer than the second sidewall 222.

[0077] Among them, the first sidewall 221 of the pipe opening is closer to the contaminant guide pipe 30 in position than the second sidewall 222 of the pipe opening.

[0078] It is understandable that the longer first sidewall 221 of the pipe opening can prevent the negative pressure channel from directly connecting to the second pipe opening 32 of the sludge collection and guiding pipe 30, blocking the waste liquid that has just flowed into the sludge storage tank from entering the negative pressure guiding pipe 20, avoiding backflow problems, thereby ensuring the omnidirectional sludge collection performance, omnidirectional liquid storage performance of the sludge storage tank and the performance of the cleaning equipment.

[0079] It can be further understood that the orientation of the second port 32 of the contaminant-collecting conduit 30 can be opposite to the orientation of the second port 22 of the negative pressure conduit 20, thereby achieving the technical effect of blocking waste liquid.

[0080] Specifically, the second port 32 of the sludge-collecting conduit 30 can be directed toward the side wall 14 of the sewage tank 10, and the second port 22 of the negative pressure conduit 20 can be directed toward the bottom 13 of the sewage tank 10; or the second port 32 of the sludge-collecting conduit 30 can be directed toward the bottom 13 of the sewage tank 10, and the second port 22 of the negative pressure conduit 20 can be directed toward the side wall 14 of the sewage tank 10.

[0081] In some embodiments, a blocking portion 321 is provided around the second port 32 of the contaminant-collecting conduit 30, and at least a portion of the blocking portion 321 is located between the second port 32 of the contaminant-collecting conduit 30 and the second port 22 of the negative pressure conduit 20.

[0082] The blocking part 321 can be installed at the second port 32 of the sewage guide pipe 30, or it can be installed on the inner wall of the sewage tank 10.

[0083] Furthermore, when the blocking part 321 is provided on one side of the second port 32 of the contaminant-collecting guide pipe 30, the blocking part 321 can also extend to the other side of the second port 32 of the contaminant-collecting guide pipe 30, thereby preventing splashing and backflow.

[0084] It is understandable that by extending the blocking part 321 to the other side of the second port 32 of the contaminant-collecting guide pipe 30, a cross-section of the second port 32 of the contaminant-collecting guide pipe 30 can be made to present a "C" shape, thereby preventing splashing and backflow.

[0085] In some embodiments, the wastewater tank 10 may include a tank cover 40 and a cavity 50. The negative pressure guide pipe 20 and the sludge collection guide pipe 30 may be disposed on the tank cover 40, and the tank cover 40 is detachably connected to the cavity 50 to form a sludge storage cavity 11.

[0086] It is understandable that by dividing the sewage tank 10 into a cover 40 and a cavity 50, and with the cover 40 being detachably connected to the cavity 50, it is convenient for users to disassemble and clean the sewage tank 10, thereby improving the user experience of the sewage storage tank and cleaning equipment.

[0087] In some embodiments, the seal 60 may include a first seal 61 and a second seal 62.

[0088] Specifically, the cover 40 may be provided with a first closing part 41, and the cavity 50 may be provided with a second closing part 51. The first closing part 41 and / or the second closing part 51 may be provided with a first sealing element 61, and the first closing part 41 is sealed and connected to the second closing part 51 through the first sealing element 61.

[0089] For example, the first seal 61 can be installed by providing mounting holes on the first cover portion 41 and / or the second cover portion 51 and providing an elastic insert on the first seal 61, thereby enabling the first seal 61 to be installed by inserting the elastic insert into the mounting hole.

[0090] Understandably, by achieving a sealed connection, the sealing performance at the cover can be improved, leakage problems can be reduced, and the safety of cleaning equipment can be enhanced.

[0091] It can be further understood that the design of the flexible plug-mounting hole can prevent the seal 60 from shifting, so that when the user disassembles the cover 40 and the cavity 50 to clean the sludge storage tank, there is no need to disassemble and reassemble the seal 60, thus ensuring the sealing and convenience of the user's installation. On the other hand, it can facilitate the installation of irregularly shaped seals 60, which not only enhances the sealing performance, but also makes it possible to design a variety of shapes for the sludge storage tank body 10.

[0092] Furthermore, an installation hole can be provided on the top of the cover 40, and an elastic insert can be provided on the second seal 62, so that the elastic insert can be inserted into the installation hole to install the second seal 62.

[0093] When the sludge storage bin is used in conjunction with cleaning equipment or separation devices, the second seal 62 can be used to improve the sealing of the mating area, thereby reducing leakage problems and improving the safety of the cleaning equipment.

[0094] Understandably, the second seal 62 can be a non-circular seal 60, which fits better at the mating point, making the cleaning equipment structure more compact.

[0095] In some embodiments, the periphery of the first port 21 of the negative pressure conduction tube 20 may be provided with an adapter surface 23.

[0096] For example, the adapter surface 23 can be an arc surface or a rounded surface.

[0097] It is understandable that by setting an adapter surface 23 around the first port 21 of the negative pressure conduction pipe 20, pressure energy loss can be reduced, noise or fluid heat energy loss can be reduced, and it can be adapted to devices such as impellers that may be set in traditional gas-liquid separation devices corresponding to the first port, so that the accidentally aspirated fluid can be directly reintroduced into the separation sewage chamber 10 by centrifugation of the impeller, preventing sewage from flowing back and being aspirated into the negative pressure channel.

[0098] In some embodiments, the sludge reservoir may also be provided with a sensor 70. It is understood that the sludge reservoir can be connected to a cleaning device, and therefore the sensor 70 can be used to enable sensors located on the cleaning device to detect the tightness and / or sealing of the connection.

[0099] In some embodiments, such as Figure 2 As shown, the sludge storage tank may also include a locking component 80, which is disposed on the sludge tank body 10.

[0100] The locking component 80 may include a first locking member 81 and a movable component 82.

[0101] Please refer to the supplementary information. Figures 7 to 9 ,like Figure 7 , Figure 8 and Figure 9 As shown, the first locking member 81 can be disposed on the sewage tank 10. For example, the first locking member 81 can be disposed on the outer periphery of the sewage tank 10. For example, the first locking member 81 can cooperate with the second locking member 83 on the cleaning device to fix the sewage tank to the cleaning device in a first direction.

[0102] The movable component 82 can be installed on the sewage tank 10. The movable component 82 is movable relative to the sewage tank 10 in a second direction and engages with the fixing groove of the cleaning equipment to fix the sewage tank to the cleaning equipment in the second direction, which is perpendicular to the first direction.

[0103] For example, the active component 82 may be disposed on the outside of the bottom 13 of the sewage tank 10.

[0104] It is understood that the movable component 82 can be movable relative to the sewage tank 10 in the second direction and can engage or disengage with the fixed slot of the cleaning equipment, thereby achieving the function of locking the sewage tank to the cleaning equipment or unlocking the sewage tank from the cleaning equipment.

[0105] In some embodiments, please refer to the supplementary information. Figure 6 ,like Figure 6 and Figure 9 As shown, the movable component 82 can be disposed on the outer side of the bottom 13 of the sewage tank 10. The movable component 82 may include a gear 821, a first movable member 822, and a second movable member 823. The gear 821 is rotatably disposed on the sewage tank 10, and the first movable member 822 can drive the second movable member 823 to move relative to the sewage tank 10 through the gear 821.

[0106] Furthermore, an elastic body 824 can be provided between the first movable component 822 and the sewage tank 10. One end of the elastic body 824 abuts against the first movable component 822, and the other end abuts against the sewage tank 10, so that the movable component 82 automatically returns to its original position after the user presses and releases it; or when the user directly pushes in the sewage storage tank, the movable component 82 utilizes the structural characteristics of the second movable component 823 (such as a wedge-shaped block, trapezoidal block, etc.) and the mechanical properties of the elastic body 824 to achieve automatic locking after pushing in. The elastic body 824 may include a spring, an elastic rubber block, etc.
