Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, and particularly to a dirt collection device for cleaning equipment. Background Art

[0002] With the steady improvement of residents' living standards, intelligent cleaning equipment is increasingly widely used in the field of household environment cleaning. Various types of equipment, such as automatic floor washers and handheld cleaning equipment, are gradually becoming powerful assistants for household cleaning. Among them, handheld cleaning equipment is deeply loved by users due to its portability and flexibility. After the equipment works continuously for a period of time, a large amount of dirt will be collected in the sewage tank. At this time, the sewage tank needs to be removed from the machine body and the internal dirt needs to be dumped.

[0003] In order to avoid clogging the sewage discharge pipeline after dumping the dirt, existing cleaning equipment usually performs solid-liquid-gas separation treatment on the collected dirt. The separated solid dirt can be directly discarded as garbage to avoid mixing into the sewage system and increasing the treatment burden. The liquid dirt (such as sewage and cleaning agent residue) can reduce the impurity content after preliminary filtration and is more likely to enter the sewage treatment system through the sewer.

[0004] However, the existing dirt collection device has a dumping dead angle when dumping solid dirt, resulting in incomplete dirt dumping and reducing the user experience. Moreover, when the device is used in a lying state, the surging water of the sewage is likely to enter the air outlet and damage the circuit of the device. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a dirt collection device for cleaning equipment. By turning the bottom cover downward and the side cover upward to completely open the inner cavity of the solid-liquid separation device, the solid dirt stored in the inner cavity can be completely dumped out, improving the cleaning efficiency and the user experience.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A dirt collection device for cleaning equipment, comprising a sewage tank body, a tank cover and a solid-liquid separation device. A sewage collection pipe is arranged inside the sewage tank body. The solid-liquid separation device is installed at the bottom of the tank cover, and the tank cover is installed on the sewage tank body. The solid-liquid separation device is located in the inner cavity of the sewage tank body and is communicated with the sewage collection pipe; The solid-liquid separation device includes a separation bracket connected to the box cover. A bottom cover is connected to the bottom of the separation bracket, and a side cover is connected to the side of the separation bracket. The bottom cover and the side cover are respectively connected to the separation bracket through a rotating shaft. A torsion spring or elastic piece for opening and maintaining the opening angle of the bottom cover and the side cover is arranged on the rotating shaft. After the bottom cover and the side cover are flipped and closed relative to the separation bracket, a cavity for storing solid dirt is formed among the three; Filter holes for communicating the cavity and the inner cavity are provided on both the bottom cover and the side cover. The opening positions of the filter holes are far from the air inlet or not in the same plane as the opening position of the air inlet, and the bottom cover is fixedly connected to the separation bracket by a snap-fastening method.

[0007] Optionally, an air outlet channel is provided between the solid-liquid separation device and the sewage tank body. The end of the air outlet channel has an air outlet connected to the main motor of the cleaning device, and both sides of the air outlet channel are abutted against the inner wall of the sewage tank body.

[0008] Optionally, a baffle for blocking water splashes from entering the air outlet is provided at the lower part of the air outlet channel; the outer edge of the baffle is abutted against the inner wall of the sewage tank body; when the air outlet channel is distributed along the axial direction of the sewage tank body, the baffle is distributed along the radial direction of the sewage tank body; when the air outlet channel is distributed at an angle relative to the axial direction of the sewage tank body, the baffle is distributed at an angle relative to the radial direction of the sewage tank body.

[0009] Optionally, convex structures abutting against the inner wall of the sewage tank body are provided on both sides of the separation bracket. An electrode rod for detecting water full and a release mechanism for releasing the bottom cover are arranged in the convex structures.

[0010] Optionally, anti-blocking holes corresponding to the electrode rods are further provided on both sides of the separation bracket, and the inner cavity and the cavity are also communicated through the anti-blocking holes.

[0011] Optionally, the release mechanism includes a connecting rod movably penetrating through the convex structure. An elastic member is sleeved on the upper part of the connecting rod, and a pull rod is arranged above the connecting rod. The middle part of the pull rod is rotatably installed on the box cover through a rotating shaft; when the pull rod rotates around the rotating shaft, it pushes the connecting rod to move downwards, and the head of the connecting rod triggers the deformation and disengagement of the snap-fastening to release the bottom cover, and the bottom parts of the electrode rod and the pull rod are sealed with the inner cavity.

[0012] Optionally, a second handle is rotatably installed on the box cover. A trigger part is arranged at the end of the second handle. When the second handle rotates, the trigger part interferes with the sewage tank body to jack up the box cover.

[0013] Optionally, a filter assembly communicating with the air outlet is installed on the box cover, and gas is drawn out of the sewage tank body after passing through the filter assembly along the air outlet passage.

[0014] Optionally, grooves are formed on one side of both the separation bracket and the bottom cover. After the solid-liquid separation device is located in the inner cavity of the sewage tank body, the sewage collection pipe is embedded in the groove and communicated with the cavity.

[0015] Optionally, the upper end of the side cover is rotatably connected to the separation bracket, and one end of the bottom cover opposite to the side cover is rotatably connected to the separation bracket, and the bottom cover, the side cover and the separation bracket are mutually clamped.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In the present invention, the dirt enters the solid-liquid separation device through the sewage collection pipe. The liquid dirt leaks from the filter holes of the solid-liquid separation device into the sewage storage area of the inner cavity of the sewage tank body, while the solid dirt remains in the inner cavity of the solid-liquid separation device, thus realizing the separation of solid dirt and liquid dirt. Moreover, both the bottom cover and the side cover of the solid-liquid separation device can be turned over and opened relative to the separation bracket, avoiding the existence of dumping dead corners after the cavity is opened, which is not only more convenient for dumping solid dirt or cleaning the separation device, but also can ensure that the dirt is dumped completely, improving the user experience. (2) In the present invention, both sides of the air outlet passage are in contact with the inner wall of the sewage tank body, and a baffle is arranged at the lower part of the air outlet passage to ensure that when the cleaning device is used in a lying state, the water splashes generated by the surging of the sewage on both sides of the air outlet are prevented from entering the air outlet, preventing damage to the circuit of the device. (3) In the present invention, there are areas higher than the electrode rods in both the normal and lying states of the solid-liquid separation device. By opening anti-blocking holes on both sides of the separation bracket, it is possible to prevent the filter holes of the bottom cover and the side cover from being blocked by solid waste, resulting in the cleaning device being unable to normally suck in dirt. (4) In the present invention, by pulling the pull rod of the release mechanism, the connecting rod is triggered to generate a downward displacement. The head of the connecting rod contacts the buckle and deforms it to release the buckle. The bottom cover and the side cover are respectively turned over to the lower side and one side of the separation bracket under the action of the torsion spring force to realize the dumping of dirt. When the pull rod is released, the connecting rod is reset under the action of the spring below. This structure can improve the efficiency of dirt dumping and prevent the user's hand from touching the dirt. (5) In the present invention, during the rotation of the second handle, its triggering part interferes with the sewage tank body and thus pushes open the sewage tank, separating the box cover from the sewage tank body, ensuring that the box cover is more convenient and labor-saving to disassemble.

[0018] Now, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention. Embodiment 1

[0019] As Figure 1 , Figure 2 and Figure 3 shown, a dirt collection device for a cleaning device includes a sewage tank body 1, a box cover 2 and a solid-liquid separation device 3; the box cover 2 can be disassembled and installed on the top of the sewage tank body 1, the solid-liquid separation device 3 is installed at the bottom of the box cover 2, and when the box cover 2 is installed on the top of the sewage tank body 1, the solid-liquid separation device 3 is located in the inner cavity of the sewage tank body 1.

[0020] Among them, a sewage collection pipeline 101 is arranged inside the sewage tank body 1. When the solid-liquid separation device 3 is installed inside the sewage tank body 1, it is communicated with the sewage collection pipeline 101; the dirt enters the solid-liquid separation device 3 through the sewage collection pipeline 101, the liquid dirt passes through the solid-liquid separation device 3 and leaks into the sewage storage area in the inner cavity, and the solid dirt remains in the inner cavity of the solid-liquid separation device 3, so as to realize the separation of solid dirt and liquid dirt.

[0021] During this process, gas also passes through the solid-liquid separation device 3 and enters the inner cavity. The gas-water fluid is separated after collision inside the solid-liquid separation device 3. The liquid flows into the sewage storage area in the inner cavity for storage, and the gas is pumped out of the sewage tank, finally realizing the three-state separation of solid, liquid and gas of the dirt.

[0022] As Figures 4 - 8 shown, the solid-liquid separation device 3 includes a separation bracket 301, a bottom cover 302 and a side cover 303. The bottom cover 302 and the side cover 303 are respectively rotatably connected to the separation bracket 301 and can be turned over and opened relative to the separation bracket 301.

[0023] The separation bracket 301 is fixedly installed at the bottom of the box cover 2. The bottom cover 302 and the separation bracket 301 can be fixedly connected by a buckle to ensure the strength and stability of the bottom cover 302 to carry and fix the dirt. And when the separation bracket 301, the bottom cover 302 and the side cover 303 are relatively closed, a cavity for storing solid dirt is formed inside the solid-liquid separation device 3, and the bottom cover 302 and the side cover 303 are respectively located at the bottom and side of the cavity.

[0024] Specifically, the upper end of the side cover 303 and the end of the bottom cover 302 opposite to the side cover 303 are rotatably connected to the separation bracket 301 through a rotating shaft. The two rotating shafts are parallel to each other, and the bottom cover 302, the side cover 303 and the separation bracket 301 are mutually clamped and can also be separated; that is, structures that can be mutually clamped are arranged at the end faces of the bottom cover 302, the side cover 303 and the separation bracket 301. The bottom cover 302 is fixedly connected to the separation bracket 301 by a buckle. At the same time, the bottom cover 302 wraps the lower end of the side cover 303 to prevent it from opening. Only after the bottom cover 302 is opened can the side cover 303 be opened.

[0025] In order to improve the convenience of garbage dumping, a torsion spring or a leaf spring is installed on the rotating shaft, and at the same time, a release mechanism 304 for opening the buckle is installed on the separation bracket 301; after the buckle is opened, under the action of the torsion spring (or leaf spring) and gravity, the bottom cover 302 automatically turns down and opens, and the side cover 303 turns away from the separation bracket 301 and opens, and all the dirt in the cavity is discharged; the torsion spring or leaf spring here is used to assist the bottom cover 302 and the side cover 303 to turn to a certain angle towards the bottom side and one side respectively, and maintain this angle to complete the dumping of dirt or user cleaning.

[0026] After the dirt enters the solid-liquid separation device 3, its solid and liquid are separated. A plurality of filter holes 305 are provided on both the bottom cover 302 and the side cover 303. After the box cover 2 is installed on the top of the sewage tank body 1, the solid-liquid separation device 3 is located in the inner cavity of the sewage tank body 1 and communicates with the sewage collection pipe 101. And the cavity and the inner cavity communicate with each other through the filter holes 305, and the opening positions of the filter holes 305 are far from the air inlet or not in the same plane as the air inlet opening position. Here, the air inlet is the opening on the separation bracket 301 that communicates with the sewage collection pipe 101.

[0027] Between the above-mentioned solid-liquid separation device 3 and the sewage tank body 1, an air outlet passage is provided. The end of the air outlet passage has an air outlet that communicates with the main motor 7 of the cleaning device, and both sides of the air outlet passage are in contact with the inner wall of the sewage tank body 1.

[0028] In order to prevent the water splashes generated by the surging of the sewage on both sides of the air outlet from entering the air outlet, the two sides of the air outlet passage can be in contact with the inner wall of the sewage tank body 1 to block the water splashes from entering the air outlet in the lying flat state.

[0029] Similarly, a baffle can also be provided at the lower part of the air outlet passage. The outer edge of the baffle is in contact with the inner wall of the sewage tank body 1 to block the water splashes from entering the air outlet, and there are two setting methods for the air outlet passage and the baffle here.

[0030] Method 1: The air outlets are distributed along the axial direction of the sewage tank body 1, and the baffles are distributed along the radial direction of the sewage tank body 1. The baffles can block the water splashes from entering the air outlets on the premise of not hindering the gas from flowing into the air outlets.

[0031] Method 2: The air outlets are distributed at a certain angle relative to the axial direction of the sewage tank body 1, and the baffles are distributed at a certain angle relative to the radial direction of the sewage tank body 1.

[0032] A filter assembly 201 communicating with the air outlet is installed on the box cover 2. The filter assembly 201 adopts an existing HEPA (High Efficiency Particulate Air) assembly, which can further filter the discharged gas and adsorb the tiny particles and harmful impurities contained therein. And after the gas overflows from the solid-liquid separation device 3, it bypasses along the gap (i.e., the air outlet passage) between the two sides of the solid-liquid separation device 3 and the inner wall of the sewage tank body 1 to the air outlet and passes through the filter assembly 201 and then is pumped out of the sewage tank body 1.

[0033] Both sides of the separation bracket 301 have a convex structure that abuts against the inner wall of the sewage tank body 1. An electrode rod 313 for detecting when the water is full and a release mechanism 304 for releasing the bottom cover 302 are provided inside the convex structure; through the electrode rod 313, the user can be reminded of the sewage storage situation in the sewage tank. The electrode rod 313 is a prior art. When the sewage in the tank reaches the full storage level, an alarm will be issued to remind the user to pour out the sewage.

[0034] The solid-liquid separation device 3 has areas higher than the electrode rod 313 in both the normal and lying states. Anti-blocking holes 312 communicating the inner cavity and the cavity are also provided on both sides of the separation bracket 301 corresponding to the electrode rod 313, and the anti-blocking holes 312 are located in the intersection area of the two states.

[0035] When the filter holes 305 on the bottom cover 302 and the side cover 303 are blocked by solid waste, it will cause the cleaning device to be unable to suck in dirt normally. The function of the anti-blocking holes 312 here is to provide another channel for the gas-liquid dirt, so as to avoid the cleaning device from malfunctioning when the filter holes 305 are blocked by solid waste.

[0036] In addition, grooves are provided on one side of both the separation bracket 301 and the bottom cover 302. After the bottom cover 302 is closed, the two grooves are coaxial. And after the solid-liquid separation device 3 is installed into the inner cavity of the sewage tank body 1, the sewage collection pipe 101 is embedded in the groove and communicated with the cavity. Through the cooperation between the sewage collection pipe 101 and the groove, the internal structure layout of the sewage tank is made more compact, and the volume of the cavity can be increased, enabling it to store more solid dirt, and it can also provide guidance during the process of installing the solid-liquid separation device 3 into the inner cavity of the sewage tank body 1, facilitating the user to more accurately complete the docking between the sewage collection pipe 101 and the solid-liquid separation device 3.

[0037] As Figures 3 - 6 shown, the buckle includes a buckle plate 321 and a buckle body 311. The buckle plate 321 is fixedly installed on the outside of the bottom cover 302, and a jack 322 corresponding to the buckle body 311 is provided on the buckle plate 321. The buckle body 311 is fixedly installed on the outside of the separation bracket 301 and protrudes outward. And after the bottom cover 302 is closed relative to the separation bracket 301, the buckle body 311 is inserted into the jack 322 to realize the fixed connection between the bottom cover 302 and the separation bracket 301.

[0038] The buckle plate 321 has a certain elasticity, and the upper part of the buckle plate 321 is folded outward to facilitate the buckle body 311 to be better inserted into the socket 322; when the bottom cover 302 is flipped upward around the axis of the second rotation axis, the upper part of the buckle plate 321 contacts the buckle body 311, and under the action of the folding structure, the buckle body 311 enters the inner side of the buckle plate 321 to stretch it open and elastically deform until the buckle body 311 is embedded in the socket 322, the tension on the buckle plate 321 disappears, and the buckle plate 321 returns to its original state, thereby realizing a fixed connection between the bottom cover 302 and the separation bracket 301.

[0039] When the connection needs to be released, the buckle plate 321 is pushed from the upper end in the direction away from the separation bracket 301, so that the buckle body 311 is disengaged from the socket 322. Then, under the action of the torsion spring and gravity, the bottom cover 302 flips downward around the axis of the second rotating shaft, the bottom end of the cavity opens, and the solid dirt can be completely poured out.

[0040] Furthermore, in order to facilitate opening the cavity of the solid-liquid separation device 3 , a release mechanism 304 for opening the buckle is provided on the separation bracket 301 .

[0041] The release mechanism 304 includes a connecting rod 342 and a pulling rod 345. The connecting rod 342 is movably inserted into the raised structures on both sides of the separation bracket 301, and an elastic member is installed on the upper part thereof. The middle part of the pulling rod 345 is rotatably installed on the box cover 2 through the rotating shaft 344, which is used to push the head (lower end) of the connecting rod 342 to contact the buckle plate 321, causing the buckle plate 321 to deform and disengage.

[0042] Among them, the raised structure of the separation bracket 301 is fixedly penetrated by a sleeve 341, and the connecting rod 342 is movably penetrated by the sleeve 341. The elastic member can adopt a spring 343 or other elastic mechanism, and the lower end of the spring 343 is connected to the top of the sleeve 341, and the upper end is connected to the top of the connecting rod 342; when the pull rod 345 flips around the rotating shaft 344 and pushes the connecting rod 342 to move downward, the head of the connecting rod 342 triggers the buckle to deform and disengage, so as to release the bottom cover 302.

[0043] Specifically, the pull rod 345 forms a lever structure under the support of the rotating shaft 344. When one end of the pull rod 345 moves upward, the other end (the head) moves downward in the opposite direction. Based on this, the outer end of the pull rod 345 is pulled upward, and its inner end moves downward, thereby pushing the connecting rod 342 to move downward along the axial direction until the head of the connecting rod 342 contacts the buckle plate 321, causing it to elastically deform and stretch outward, so that the buckle body 311 is disengaged from the buckle plate 321; after the buckle is opened, the bottom cover 302 and the side cover 303 are flipped to the lower side and one side of the separation bracket 301 respectively under the action of the torsion spring force, thereby realizing the dumping of dirt, improving the efficiency of dirt dumping, and avoiding the user's hands from touching the dirt.

[0044] After the release is completed, release the pull rod 345. Under the action of the spring 343, the connecting rod 342 resets and its lower end moves upward, enabling the buckle to engage again. After the bottom cover 302 and the side cover 303 are opened, more of the interior cavity is exposed, facilitating subsequent cleaning.

[0045] To improve the stable reliability of the connection between the bottom cover 302 and the separation bracket 301, two sets of buckles are provided, relatively distributed on both sides of the bottom cover 302 adjacent to the side cover 303. Similarly, two sets of release mechanisms 304 are also correspondingly provided. However, to simplify the structure, the two sets of release mechanisms 304 share a rotating shaft 344, and the outer ends of the two pull rods 345 are fixedly connected together by a cross bar to ensure the synchronization of the releases on both sides.

[0046] In addition, to improve the sealing performance of the device, a seal 5 is provided between the outer side of the upper end of the separation bracket 301 and the inner wall of the sewage tank body 1, and the seal 5 is made of rubberized coating. Similarly, a sealing component is also provided at the connection between the sewage collection pipe 101 and the separation bracket 301, and the bottoms of the electrode rod 313 and the pull rod 345 are sealed with the inner cavity of the sewage tank body 1.

[0047] A second handle 202 is provided at the top of the box cover 2. The second handle 202 is rotatably installed on both sides of the box cover 2, and a trigger portion is provided at the end of the second handle 202. During the rotation of the second handle 202, interference occurs between the trigger portion and the sewage tank body 1, and the box cover 2 is lifted from the sewage tank body 1 by the reverse force, causing the two to separate. Then, the box cover 2 and the solid-liquid separation device 3 are taken out of the sewage tank body 1 through the second handle 202, ensuring that the disassembly of the box cover 2 is more convenient and labor-saving.

[0048] Working principle: The dirt enters the solid-liquid separation device 3 through the sewage collection pipe 101 in the sewage tank body 1. The liquid dirt leaks through the filter holes 305 of the solid-liquid separation device 3 into the sewage storage area in the inner cavity, while the solid dirt remains in the cavity of the solid-liquid separation device 3, thus realizing the separation of solid dirt and liquid dirt. At the same time, the gas bypasses from the gaps between the two sides of the solid-liquid separation device 3 and the inner wall of the sewage tank body 1 to the air outlet, passes through the filter assembly 201, and is then evacuated from the sewage tank body 1. After removing the sewage tank body 1 and the box cover 2 as a whole from the cleaning device and removing the box cover 2 from the sewage tank body 1, the bottom cover 302 of the solid-liquid separation device 3 can be opened. After the bottom cover 302 of the solid-liquid separation device 3 is opened, the side cover 303 of the solid-liquid separation device 3 is also in an openable state, and then the large-particle solid dirt can be poured out. At the same time, the liquid dirt and small-particle dirt in the sewage tank body 1 can also be poured out. Embodiment 2

[0049] Based on Embodiment 1, the present invention further provides a cleaning device that applies the dirt collection device proposed in Embodiment 1.

[0050] As Figures 1 - 9 shown, a cleaning device includes a body 6. Inside the body 6, a main motor 7 for generating negative pressure is installed. Below the main motor 7, a detachable sewage tank is provided. The sewage tank includes the aforementioned sewage tank body 1, a tank cover 2, and a solid-liquid separation device 3. Below the body 6, a floor brush assembly 8 is connected. The dirt suction port of the floor brush assembly 8 is communicated with a sewage collection pipe 101, so as to be communicated with the sewage tank.

[0051] After the sewage tank is installed in the body 6, the air inlet end of the main motor 7 is communicated with the air outlet through a filter assembly 201. After the main motor 7 is started, a negative pressure suction force is generated. Under the action of the suction force, external dirt enters the sewage collection pipe 101 along the dirt suction port of the floor brush assembly 8 and enters the cavity of the solid-liquid separation device 3. Under the action of the solid-liquid separation device 3, solid-liquid separation of the dirt is realized, and at the same time, gas-water separation is realized. The solid dirt remains in the cavity, the liquid dirt remains in the dirt storage area of the inner cavity, and the gas bypasses from the gaps between the two sides of the solid-liquid separation device 3 and the inner wall of the sewage tank body 1 to the air outlet. Under the action of the suction force, it passes through the filter assembly 201 and is then pumped out of the sewage tank, and is finally discharged to the external environment under the action of the main motor 7.

[0052] On the outer side of the sewage tank body 1, a first handle 102 for convenient taking is provided. The sewage tank and the body 6 are connected by an existing method, and a release button is provided on the outer side of the tank cover 2. After pressing the release button, the connection between the sewage tank and the body 6 is released, and at this time, the sewage tank can be removed from the body 6.

[0053] In order to reduce the odor of the sewage, a deodorization component 4 is further connected below the bottom cover 302. The deodorization component 4 includes a deodorization box, and the deodorization box is filled with a deodorant. When the solid-liquid separation device 3 is installed in the inner cavity of the sewage tank body 1, the deodorization component 4 is located in the sewage storage area of the inner cavity to facilitate deodorization of the sewage.

[0054] In summary, the dirt collection device proposed by the present invention includes a sewage tank body 1, a tank cover 2, and a solid-liquid separation device 3. The bottom cover 302 and the side cover 303 of the solid-liquid separation device 3 can be opened and closed relative to the separation bracket 301 to facilitate completely pouring out solid dirt or cleaning the solid-liquid separation device 3. The air outlet is located outside the solid-liquid separation device 3 and on the upper side of the sewage tank. The baffle can block the water splashes generated by surging during use from entering the air outlet, and under the action of the anti-blocking holes 312, it can prevent the openings of the bottom cover 302 and the side cover 303 of the solid-liquid separation device 3 from being blocked by solid waste, resulting in the inability of the cleaning device to normally suck in dirt.
