Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and particularly relates to a sewage tank and a cleaning equipment. Background Art

[0002] A floor washer is a cleaning machine suitable for cleaning hard floors while sucking up sewage and taking the sewage away from the site, and has the advantages of environmental protection, energy saving, high efficiency, etc.

[0003] The floor washer includes a fan and a sewage tank. An air outlet and a sewage channel are arranged in the sewage tank, and the air outlet is communicated with the fan. Under the action of the fan, the sewage is sucked into the sewage tank through the sewage channel. The air flow enters the fan through the air outlet and is discharged from the sewage tank by the fan.

[0004] However, when the sewage enters the sewage tank through the sewage channel, most of the sewage is directly sprayed on the inner wall of the sewage tank, which easily causes dirt and water stains to adhere to the inner wall of the sewage tank. Utility Model Content

[0005] This application provides a sewage tank and a cleaning equipment to solve the problem that the sewage is sprayed on the inner wall of the sewage tank, resulting in dirt and water stains adhering to the inner wall of the sewage tank.

[0006] On the one hand, this application provides a sewage tank, which includes a box body, a cover body and a water guiding member;

[0007] The water guiding member includes a water guiding main body portion and a supporting portion arranged on the water guiding main body portion;

[0008] The cover body covers the box body. Both the water guiding main body portion and the supporting portion are located in the box body. The water guiding main body portion is arranged between the cover body and the supporting portion. The supporting portion abuts against the inner wall of the box body and divides the box body into a sewage chamber and a mixing chamber. The water guiding main body portion is located in the mixing chamber. An air outlet channel is arranged on the cover body, and a sewage channel is arranged in the box body. Both the air outlet channel and the sewage channel are communicated with the mixing chamber;

[0009] The water guiding main body portion is configured to separate the air outlet channel from the sewage channel to prevent the sewage entering from the sewage channel from spraying on the inner wall of the box body.

[0010] In this way, the water guiding main body portion corresponds to the water outlet of the sewage channel. The sewage sprayed from the sewage channel is intercepted by the water guiding main body portion and then flows along the water guiding main body portion into the sewage chamber, avoiding the sewage directly spraying on the inner wall of the box body, resulting in dirt and water stains adhering to the inner wall of the box body; the water guiding main body portion separates the air outlet channel from the sewage channel. When the sewage is sprayed, the sewage and the solid impurities carried by it enter the sewage chamber directly from the mixing chamber under the guidance of the water guiding main body portion, avoiding the two entering the air outlet channel under the influence of the air flow and causing blockage.

[0011] In a possible implementation, the sewage tank provided in the present application has a first filter portion disposed on the support portion, and the first filter portion is used to filter solid impurities in the sewage entering the sewage cavity.

[0012] In this way, when the sewage flows along the water guide body to the sewage cavity, the solid impurities carried by the sewage fall on the first filter part, and the sewage enters the sewage cavity so as to separate the solid impurities carried by the sewage, making it convenient to subsequently treat the sewage and solid impurities in the sewage tank separately.

[0013] In a possible implementation, the sewage tank provided in the present application has a water guiding channel disposed in a water guiding body, the sewage channel is connected to the water guiding channel, a first connecting port is disposed on the water guiding body, and the water guiding channel is connected to the mixing chamber through the first connecting port.

[0014] In this way, the water guide body is arranged around the sewage channel through the water guide channel to enhance the blocking effect on the sewage and the solid impurities contained therein. After being blocked by the water guide body, the sewage and the solid impurities contained therein can flow along the water guide body through the first connecting port into the mixing chamber.

[0015] In a possible implementation, the sewage tank provided in the present application has a support tube in the tank body, the inner wall of the support tube forms a sewage channel, the support portion is inserted on the support tube, and part of the support tube is located in the water guide channel.

[0016] In this way, the stability of the support part in the box body is improved, and the sewage sprayed out of the sewage channel enters the water guide channel.

[0017] In a possible implementation, in the sewage tank provided by the present application, a water diversion portion is provided at one end of the support pipe located in the water diversion channel;

[0018] The water guide portion is configured to spray the sewage away from the first communication port.

[0019] In this way, when sewage is sprayed out from the sewage channel, under the action of the water guide part, it is sprayed away from the first communication port onto the inner wall of the water guide channel, thereby preventing sewage from being sprayed out directly from the first communication port.

[0020] In a possible implementation, the sewage tank provided in the present application has a support portion provided with a mounting through hole for inserting a support pipe.

[0021] In this way, the support portion can be inserted into the support tube through the installation through hole, so that one end of the support tube extends into the water guide channel through the installation through hole.

[0022] In a possible implementation, in the sewage tank provided in the present application, the first communication port is a notch provided on the water-conducting main body, and the opening of the notch faces the supporting portion.

[0023] In this way, the water guiding main body and the supporting part enclose to form a first communication port, and the first communication port is located at one end of the water guiding main body away from the cover body. After the sewage is sprayed into the water guiding channel, it flows downward along the water guiding channel to the first communication port and enters the mixing cavity through the first communication port.

[0024] In a possible implementation manner, for the sewage tank provided in this application, the extending length of the notch is less than or equal to one-half of the extending length of the water guiding main body and greater than or equal to one-third of the extending length of the water guiding main body.

[0025] In this way, the notch has a suitable opening range, avoiding the first communication port formed by the notch being too large, so that the sewage is easily ejected from the first communication port, resulting in a poor blocking effect of the water guiding main body on the sewage. Or, avoiding the first communication port formed by the notch being too small, where the solid impurities carried in the sewage accumulate at the first communication port, resulting in blockage.

[0026] In a possible implementation manner, for the sewage tank provided in this application, a second filtering part is provided on the cover body, and the second filtering part is used to filter the gas discharged from the air outlet channel.

[0027] In this way, the solid impurities carried by the air flow can enter the air outlet channel from the air outlet cavity, and the second filtering part can intercept the solid impurities to prevent the solid impurities from entering the dust suction component in the cleaning device and causing damage to it.

[0028] In a possible implementation manner, for the sewage tank provided in this application, it further includes at least one sealing member, and the sealing member is provided at least at one of the positions between the cover body and the box body and between the box body and the supporting part.

[0029] In this way, the sealing performance between the cover body and the box body and / or between the box body and the supporting part can be improved.

[0030] On the other hand, this application provides a cleaning device, including a device main body and the sewage tank as described above, and the sewage tank is connected to the device main body.

[0031] In this way, for the device main body provided with the above sewage tank, the sewage sprayed from the sewage channel is intercepted by the water guiding main body and then flows along the water guiding main body to the sewage cavity, avoiding the sewage directly spraying on the inner wall of the box body, resulting in dirt and water stains sticking to the inner wall of the box body.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0049] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, or an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0050] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0051] The terms "first", "second", "third" (if any) in the description and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0052] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0053] In the related art, a floor washer includes a blower and a sewage tank. An air outlet and a sewage channel are provided in the sewage tank, and the air outlet is communicated with the blower. Under the action of the blower, sewage is sucked into the sewage tank through the sewage channel. Air flows into the blower through the air outlet and is discharged from the blower out of the sewage tank.

[0054] However, when sewage enters the sewage tank through the sewage channel, most of the sewage is directly sprayed on the inner wall of the sewage tank, which easily causes dirt and water stains to adhere to the inner wall of the sewage tank and is difficult to clean. Moreover, when the sewage is sprayed on the inner wall of the sewage tank, some splashed sewage and lighter solid impurities will enter the air outlet along with the airflow due to the action of the wind, resulting in blockage.

[0055] In view of the above problems, the present application provides a sewage tank and a cleaning device. The sewage sprayed from the sewage channel by the sewage tank is intercepted by the water guiding main body part, and then flows along the water guiding main body part to the sewage cavity, avoiding the sewage being directly sprayed on the inner wall of the box body, resulting in dirt and water stains adhering to the inner wall of the box body; the water guiding main body part separates the air outlet channel from the sewage channel. When the sewage is sprayed, the sewage and the solid impurities carried by it directly enter the sewage cavity from the mixing cavity under the guidance of the water guiding main body part, avoiding the two from entering the air outlet channel under the influence of the airflow and causing blockage.

[0056] The following will describe in detail the specific embodiments of the sewage tank and the cleaning device provided by the embodiments of the present application with reference to the accompanying drawings.

[0057] Refer to Figures 1 to 6 As shown, the sewage tank provided by the present application includes a box body 100, a cover body 200, and a water guiding member 300.

[0058] The water guiding member 300 includes a water guiding main body part 310 and a supporting part 320 provided on the water guiding main body part 310.

[0059] The cover body 200 is covered on the box body 100. Both the water guiding main body part 310 and the supporting part 320 are located inside the box body 100. The water guiding main body part 310 is arranged between the cover body 200 and the supporting part 320. The supporting part 320 abuts against the inner wall of the box body 100 and divides the box body 100 into a sewage cavity 110 and a mixing cavity 120. The water guiding main body part 310 is located in the mixing cavity 120. An air outlet channel 400 is provided on the cover body 200, and a sewage channel 130 is provided inside the box body 100. Both the air outlet channel 400 and the sewage channel 130 are communicated with the mixing cavity 120.

[0060] The water guiding main body part 310 is configured to separate the air outlet channel 400 from the sewage channel 130 to prevent the sewage entering from the sewage channel 130 from spraying on the inner wall of the box body 100.

[0061] It should be understood that the sewage tank provided in this application is mainly used in a cleaning device, which can be a floor washer. The floor washer can include a dust suction component for providing suction to suck away the sewage on the surface to be cleaned through negative pressure, and the sewage tank is used to recycle the sewage.

[0062] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, when the sewage tank is in an upright state, the mixing chamber 120 is located above the sewage chamber 110. Sewage enters the mixing chamber 120 inside the box body 100 through the sewage channel 130 and then flows into the sewage chamber 110. The air flow sucked into the box body 100 by the dust suction component enters the dust suction component through the air outlet channel 400 from the mixing chamber 120.

[0063] To prevent the sewage channel 130 from directly spraying sewage on the inner wall of the box body 100, in this application, a water guiding main body 310 is provided on the cover body 200. The water guiding main body 310 corresponds to the water outlet of the sewage channel 130. The sewage sprayed out from the sewage channel 130 is intercepted by the water guiding main body 310 and then flows along the water guiding main body 310 into the sewage chamber 110, preventing the sewage from directly spraying on the inner wall of the box body 100 and causing dirt and water stains to stick to the inner wall of the box body 100.

[0064] It can be understood that for the dirt and water stains sticking to the water guiding main body 310, the water guiding main body 310 can be taken out of the box body 100 for cleaning.

[0065] And, referring to Figure 1 、 Figure 2 and Figure 3 As shown, the water guiding main body 310 separates the air outlet channel 400 from the sewage channel 130. When sewage is sprayed out, the sewage and the solid impurities it carries are directly guided by the water guiding main body 310 from the mixing chamber 120 into the sewage chamber 110, preventing them from entering the air outlet channel 400 under the influence of the air flow and causing blockage.

[0066] Exemplarily, the water guiding main body 310 can be an arc-shaped plate structure, a cylindrical structure or a conical structure, or other shapes, as long as the water guiding main body 310 can block the sewage from directly spraying on the inner wall of the box body 100 and guide the sewage and the solid impurities it carries to flow into the sewage chamber 110. This application embodiment does not impose too many restrictions on this.

[0067] The sewage tank provided by the present application includes a box body 100, a cover body 200, and a water guiding member 300. The water guiding member 300 includes a water guiding main body portion 310 and a supporting portion 320 provided on the water guiding main body portion 310. The water guiding main body portion 310 is disposed between the cover body 200 and the supporting portion 320. The supporting portion 320 abuts against the inner wall of the box body 100 and divides the box body 100 into a sewage chamber 110 and a mixing chamber 120. An air outlet passage 400 is provided on the cover body 200, and a sewage passage 130 is provided in the box body 100. The water guiding main body portion 310 corresponds to the water outlet of the sewage passage 130. The sewage sprayed out from the sewage passage 130 is intercepted by the water guiding main body portion 310 and then flows along the water guiding main body portion 310 into the sewage chamber 110, preventing the sewage from directly spraying on the inner wall of the box body 100 and causing dirt and water stains to adhere to the inner wall of the box body 100. The water guiding main body portion 310 separates the air outlet passage 400 from the sewage passage 130. When the sewage is sprayed out, the sewage and the solid impurities carried by it directly enter the sewage chamber 110 from the mixing chamber 120 under the guidance of the water guiding main body portion 310, preventing the two from entering the air outlet passage 400 under the influence of the air flow and causing blockage.

[0068] Referring Figure 2 and Figure 3 As shown, in a possible implementation manner, a first filtering portion 321 is provided on the supporting portion 320. The first filtering portion 321 is used to filter the solid impurities in the sewage entering the sewage chamber 110.

[0069] In this way, when the sewage flows along the water guiding main body portion 310 towards the sewage chamber 110, the solid impurities carried by the sewage fall on the first filtering portion 321, and the sewage enters the sewage chamber 110, so as to separate the solid impurities carried by the sewage, facilitating subsequent treatment of the sewage and solid impurities in the sewage tank respectively.

[0070] Exemplarily, referring Figure 2 As shown, the first filtering portion 321 may be a filter screen.

[0071] Referring Figure 2 and Figure 4 As shown, in a possible implementation manner, a water guiding passage 311 is provided in the water guiding main body portion 310. The sewage passage 130 is communicated with the water guiding passage 311, and a first communication port 312 is provided on the water guiding main body portion 310. The water guiding passage 311 is communicated with the mixing chamber 120 through the first communication port 312.

[0072] In this way, the water guiding main body portion 310 surrounds the sewage passage 130 through the water guiding passage 311 to improve the blocking effect on the sewage and the solid impurities carried by it. After the sewage and the solid impurities carried by it are blocked by the water guiding main body portion 310, they can enter the mixing chamber 120 along the water guiding main body portion 310 through the first communication port 312.

[0073] Exemplarily, referring to Figure 2 , Figure 3 and Figure 4 as shown, the first communication port 312 can be located at one end of the water guiding main body 310 away from the cover body 200. When the sewage tank is in an upright state, the water outlet of the sewage channel 130 is located above the first communication port 312, so as to prevent part of the sewage from directly spraying out from the first communication port 312, causing the sewage to spray on the inner wall of the box body 100. After the sewage sprays into the water guiding channel 311, it flows downward along the water guiding channel 311 to the first communication port 312, and enters the mixing chamber 120 through the first communication port 312.

[0074] Wherein, the distance between the outer wall of the water guiding main body 310 and the inner wall of the box body 100 can be 8 mm to 12 mm to leave a movement space for air flow, sewage and solid impurities. Specifically, the distance between the outer wall of the water guiding main body 310 and the inner wall of the box body 100 is 10 mm.

[0075] Referring to Figure 3 , Figure 4 and Figure 6 as shown, in specific implementation, a support pipe 140 is provided in the box body 100, the inner wall of the support pipe 140 forms the sewage channel 130, the support part 320 is inserted on the support pipe 140, and part of the support pipe 140 is located in the water guiding channel 311.

[0076] In this way, the support part 320 is inserted on the support pipe 140 to improve the stability of the support part 320 in the box body 100. One end of the support part 320 is arranged in the sewage chamber 110, and the other end extends into the water guiding channel 311 through the support part 320, so that the sewage sprayed out from the sewage channel 130 enters the water guiding channel 311, and then flows along the water guiding channel 311 to the mixing chamber 120.

[0077] Referring to Figure 4 and Figure 6 as shown, in a possible implementation manner, a water guiding part 141 is arranged at one end of the support pipe 140 located in the water guiding channel 311.

[0078] The water guiding part 141 is configured to make the sewage spray away from the first communication port 312.

[0079] In this way, when the sewage sprays out from the sewage channel 130, under the action of the water guiding part 141, it sprays on the inner wall of the water guiding channel 311 away from the first communication port 312, thus preventing the sewage from directly spraying out from the first communication port 312.

[0080] Referring to Figure 2 as shown, in a possible implementation manner, an installation through hole 322 for inserting the support pipe 140 is arranged on the support part 320.

[0081] In this way, the supporting part 320 can be inserted onto the supporting pipe 140 through the installation through-hole 322, so that one end of the supporting pipe 140 extends into the water guiding channel 311 through the installation through-hole 322.

[0082] Referring to Figure 2 As shown, in a possible implementation manner, the first communication port 312 is a notch provided on the water guiding main body part 310, and the opening of the notch faces the supporting part 320.

[0083] In this way, the water guiding main body part 310 and the supporting part 320 enclose to form the first communication port 312, and the first communication port 312 is located at one end of the water guiding main body part 310 away from the cover body 200. After the sewage is sprayed in the water guiding channel 311, it flows downward along the water guiding channel 311 to the first communication port 312, and enters the mixing cavity 120 through the first communication port 312.

[0084] In specific implementation, the extending length of the notch is less than or equal to one-half of the extending length of the water guiding main body part 310 and greater than or equal to one-third of the extending length of the water guiding main body part 310.

[0085] In this way, the notch has an appropriate opening range, avoiding that the first communication port 312 formed by the notch is too large, so that the sewage is easily sprayed out from the first communication port 312, resulting in a poor blocking effect of the water guiding main body part 310 on the sewage. Or, avoiding that the first communication port 312 formed by the notch is too small, so that the solid impurities carried in the sewage accumulate at the first communication port 312, resulting in blockage.

[0086] It can be understood that, referring to Figure 4 As shown, when the box body 100 is in an upright state, the direction indicated by X is the vertical direction, the extending length L1 of the water guiding main body part 310 is the length of the water guiding main body part 310 along the vertical direction, and the extending length L2 of the notch is the length of the notch along the vertical direction.

[0087] Referring to Figure 2 、 Figure 3 and Figure 5 As shown, in a possible implementation manner, the sewage tank provided by the present application further includes a water blocking member 500.

[0088] The water blocking member 500 is arranged on the water guiding main body part 310. The water blocking member 500 divides the mixing cavity 120 into an air outlet cavity 121 and a sub-mixing cavity 122. A second communication port 510 communicating the air outlet cavity 121 and the sub-mixing cavity 122 is provided on the water blocking member 500.

[0089] The air outlet cavity 121 is communicated with the air outlet channel 400, the sub-mixing cavity 122 is communicated with the sewage cavity 110, and the sub-mixing cavity 122 is communicated with the water guiding channel 311 through the first communication port 312. The first filtering part 321 corresponds to the sub-mixing cavity 122.

[0090] In this way, when the box body 100 lies flat, the sub-mixing cavity 122 is located below the air outlet cavity 121, and sewage will enter the sub-mixing cavity 122 from the sewage cavity 110. Since the air outlet channel 400 communicating with the air outlet cavity 121 is separated from the sewage by the water baffle 500, and the water baffle 500 reduces the surge space of the sewage, the surge is suppressed, and the sewage cannot directly splash into the air outlet channel 400, resulting in water spraying in the air outlet channel 400.

[0091] Moreover, as shown in Figure 3 and Figure 5 , a second communication port 510 communicating the air outlet cavity 121 and the sub-mixing cavity 122 is formed on the water baffle 500. The air flow inhaled into the box body 100 by the dust suction assembly can enter the air outlet cavity 121 from the sub-mixing cavity 122 through the second communication port 510, and then enter the air outlet channel 400 through the air outlet cavity 121.

[0092] Exemplarily, as shown in Figure 1 and Figure 2 , the number of the water baffles 500 can be two, and the two water baffles 500 are respectively arranged on both sides of the water guiding main body portion 310.

[0093] As shown in Figure 1 , in a possible implementation manner, a second filtering portion 210 is arranged on the cover body 200, and the second filtering portion 210 is used for filtering the gas discharged from the air outlet channel 400.

[0094] In this way, the solid impurities carried by the air flow can be intercepted by the second filtering portion 210 after entering the air outlet channel 400 from the air outlet cavity 121, preventing the solid impurities from entering the dust suction assembly in the cleaning device and causing damage to it.

[0095] It can be understood that, as shown in Figure 1 , Figure 3 and Figure 4 , the air outlet channel 400 has a gas inlet 410 and a gas outlet 420. The gas inlet 410 is located in the air outlet cavity 121 and communicates with the air outlet cavity 121, and the gas outlet 420 is located outside the box body 100. The second filtering portion 210 is arranged at the gas outlet 420 of the air outlet channel 400, and the air outlet channel 400 communicates with the dust suction assembly in the cleaning device through the gas outlet 420.

[0096] Exemplarily, the second filtering portion 210 can be a nylon mesh piece, a HEPA filter, a filter cotton, etc., and the specific form is not limited herein.
