Description

Technical Field

[0001] The utility model relates to the technical field of hand warming equipment, in particular to a water spraying and dust suction device for an electric mop and an electric mop. Background Art

[0002] At present, floor cleaning in the market generally uses traditional manual mopping or electric mops.

[0003] For traditional manual mopping, the mop is first soaked, and then the soaked mop is rubbed back and forth on the ground. In this way, after the mop adheres to dust and other stains, the mop becomes dirty, and then the dirty mop is rubbed back and forth on the ground, resulting in poor cleaning effect.

[0004] Electric mops are divided into dry mopping and wet mopping. When wet mopping, the electric mop first sprays water, and then the mop rubs on the ground with water and stains. This way will still cause the mop to become dirty and affect the cleaning effect.

[0005] In order to improve the cleaning effect, there appears a mopping machine with integrated suction and mopping on the market. During the mopping process of this mopping machine with integrated suction and mopping, it first dry-sucks the impurity particles on the ground, and then sprays water for wet mopping. Because this method is dry-suction first and then wet mopping, the dry suction cannot completely suck away the impurity particles on the ground. Especially some tiny impurity particles with small particle sizes that are easy to disperse, such as floating dust, are difficult to be completely sucked clean. In the subsequent wet mopping process, the mixture formed by these tiny impurity particles after being sprayed with water will still adhere to the mop and affect the cleaning effect during the mopping process.

[0006] Therefore, the existing technology needs to be improved. Content of the Utility Model

[0007] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide a water spraying and dust suction device for an electric mop and an electric mop, aiming to improve the cleaning effect of the electric mop during the mopping process.

The water spraying module sprays mopping water towards the forward direction of mopping through the spray outlet, and the landing position of the mopping water is in front of the corresponding suction position of the suction inlet on the ground, so that the impurity particles on the ground first form a mixture with the mopping water and then are sucked away by the water absorption module from the suction inlet.

[0011] In some examples, the landing position of the mopping water ejected from the ejection port is within the range of 0 to 10 cm in front of the suction position.

[0012] In some examples, the shape of the landing position of the mopping water ejected from the ejection port is a line in the forward direction of mopping. The length of the line is 1 to 4 cm, and the starting point of the line is 2 to 5 cm away from the suction position.

The ejection port is arranged on the nozzle, and the suction port is arranged on the suction nozzle. The water spraying module and the water absorption module are accommodated in the storage housing;

[0014] A gas-liquid separation structure is arranged at the position where the storage housing is connected to the nozzle and the suction nozzle.

[0017] The suction nozzle is detachably connected to the bottom surface of the first water baffle inclined plate, and a plurality of the ejection ports are arranged at the front end of the installation position of the suction nozzle on the bottom surface of the first water baffle inclined plate.

[0018] In some examples, the angle between the second water baffle inclined plate and the horizontal plane is 40 to 90 degrees, and the angle between the first water baffle inclined plate and the second water baffle inclined plate is 25 to 40 degrees.

[0019] In some examples, the suction nozzle includes a hollow first housing and a second housing;

[0020] An inhalation window for docking with the air passage is arranged on the side wall of the first housing, and the top wall of the first housing is mounted on the nozzle;

[0021] The second housing is in the shape of a flared mouth with a large upper part and a small lower part. The upper end of the second housing is connected to the first housing, and the lower end of the second housing is provided with the suction port.

[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0027] During the process of pushing the product forward before mopping the floor, water is first sprayed to mix the ground impurities with water, and then the mixture formed by the impurity particles and water is sucked away through the suction nozzle. In this way, the large particles and fine impurity particles (such as floating dust) on the wetted ground are basically sucked away, and only some water that has not been sucked away remains on the ground. At this time, there are no stains on the ground. When the mop cloth mops the ground subsequently, it only dries the water that has not been sucked away, and the mop cloth will not be contaminated by the stains that previously existed on the ground, greatly improving the ground cleaning effect.

[0046] The present utility model includes the following embodiments.

[0047] Embodiment 1. Please refer to Figures 1 to 8 , this embodiment provides a water spraying and dust suction device 100a for an electric mop, including a body 1, and a water spraying module 2 and a water suction module 3 are arranged in the body 1. The water spraying module 2 is used to spray clean mopping water onto the ground to be cleaned, while the water suction module 3 is used to suck away the impurity particles and liquid on the ground.

[0048] Specifically, as Figure 2 shown, in this embodiment, the water spraying module 2 includes a clean water tank 21, a water pump 22, a water inlet pipe 23, and a water outlet pipe 24. The water inlet pipe 23 is connected between the water pump 22 and the clean water tank 21, and the water pump 22 is also connected with the water outlet pipe 24. The clean water tank 21 is provided with a water filling port (not shown). After the water pump 22 is powered on, it pumps the clean water in the clean water tank 21 into the water pump 22 through the water inlet pipe 23, and then discharges it through the water outlet pipe 24.

[0049] In this embodiment, the water suction module 3 includes a sewage tank 31, a fan 32, and a suction pipeline 33. The fan 32 is connected to the suction pipeline 33, and the suction pipeline 33 is also connected to the sewage tank 31. An air inlet 34 is provided at the front end of the suction pipeline 33. After the fan 32 is powered on, a negative pressure is generated in the suction pipeline 33, and then gas, liquid, etc. are sucked into the suction pipeline 33 from the air inlet 34 and finally enter the sewage tank 31. The sewage tank 31 is provided with a sewage discharge port (not shown).

[0050] In this embodiment, as Figure 1 shown, a water spraying outlet 4 communicating with the water spraying module 2 is provided on the surface of the main body 1, and a water suction inlet 5 communicating with the water suction module 3 is further provided on the surface of the main body 1. Specifically, the water spraying outlet 4 communicates with the water outlet pipe 24 of the water spraying module 2, and the water suction inlet 5 communicates with the suction pipeline 33 of the water suction module 3.

[0051] The water spraying module 2 sprays the water for mopping the floor in the forward direction of mopping. As Figure 3 shown, the landing position of the water for mopping the floor (assumed to be point B) is on the front side of the corresponding suction position on the ground of the water suction inlet 5 (assumed to be point A), so that the impurity particles on the ground first form a mixture with the water for mopping the floor and then are sucked away by the water suction module 3 from the water suction inlet 5.

[0052] That is, the working principle of the water spraying and dust suction device 100a in this embodiment is as follows:

[0053] When the electric mop mops the floor, first turn on the power supply, and then control the circuit to work. In the forward direction of mopping, as Figure 3 shown, the water pump 22 of the water spraying module 2 of the water spraying and dust suction device 100a starts, pumps the clean water in the clean water tank 21 through the water inlet pipe 23, and then discharges it to the water spraying outlet 4 through the water outlet pipe 24. The clean water for mopping the floor is sprayed onto the ground to be cleaned in the forward direction of mopping under the pressure of the water pump 22. After the ground to be cleaned is sprayed with water, the impurity particles on the ground first form a mixture with the water for mopping the floor. In this way, the large and small particles in the impurity particles, especially the small particle floating dust, will also be stuck by the water and adhered to the ground. Then, because the landing position B of the water for mopping the floor is in front of the corresponding suction position A of the water suction inlet 5 on the ground in the forward direction of mopping, the impurity particles on the ground in front of the suction position A have all formed a mixture with the water for mopping the floor. Then, when moving the electric mop forward, at the same time, turn on the fan 32, a negative pressure is generated in the suction pipeline 33, and the mixture formed by the impurity particles on the ground in front of the water suction inlet 5 and the water for mopping the floor is sucked into the suction pipeline 33 from the water suction inlet 5 and finally stored in the sewage tank 31. After being adsorbed, there are basically no impurity particles on the ground. Subsequently, during the forward movement of the electric mop, the mopping tools such as the mop cloth only dry the water on the ground, and the mop cloth will not be stained. In this way, the mopping method of spraying water first, then adsorbing, and then mopping, that is, the mopping method of wet suction first and then mopping, greatly improves the cleaning effect of the ground.

[0054] The mopping method of the electric mop corresponding to the water spraying and dust suction device 100a in this embodiment is as follows. On the one hand, before mopping the floor, large and small impurity particles on the ground are pre-fixed to the ground by mixing with water and then uniformly adsorbed. In this way, the impurity particles on the ground can be cleaned more thoroughly compared with dry suction in the prior art, rather than being unable to clean small particle impurities such as floating dust as in the prior art. Then, on the other hand, when mopping the floor subsequently, the mop and the like are specifically used to dry the water stains on the ground, and the mop will not be contaminated by uncleaned impurity particles such as dust and repeatedly used to mop the floor, resulting in the floor never being cleaned thoroughly. The combination of the two aspects greatly improves the cleaning effect of the electric mop corresponding to the water spraying and dust suction device 100a of the present utility model during the mopping process.

[0055] The control circuit in this embodiment can be arranged in the main body 1 of the water spraying and dust suction device 100a, or can be arranged on the electric mop.

[0056] In this embodiment, the landing position of the mopping water sprayed from the spray outlet 4 is within the range of 0 to 10 cm in front of the suction position. The landing position of the mopping water sprayed from the spray outlet 4 of the present utility model can be dot-shaped or line-shaped on the straight line in the forward direction of mopping. As Figure 3 shown, the landing position of the mopping water sprayed from the spray outlet 4 on the straight line in the forward direction of mopping can be point B, or point C, or point A, or any point between A and B (assuming that point B is the farthest point of the landing position of the mopping water sprayed from the spray outlet 4). Or the landing position of the mopping water sprayed from the spray outlet 4 on the straight line in the forward direction of mopping can be any line between A and B (assuming that point B is the farthest point of the line), such as line CA. In the present utility model, regardless of whether the landing position of the mopping water after spraying is dot-shaped or line-shaped, it is within the range of 0 to 10 cm in front of the suction position (position A in the figure), so as to ensure that the ground before and after the landing position can be splashed wet after the mopping water lands, so that the impurity particles on the ground in front of point A of the suction position can be mixed with the sprayed mopping water, facilitating subsequent suction cleaning.

[0057] Preferably, the landing position of the mopping water sprayed from the spray outlet 4 is at the 4 cm position in front of the suction position. After the mopping water lands here, the mopping water collides and splashes with the ground, and can splash wet all the ground between the landing position (assuming it is point B) and the suction position A, so that the impurity particles on this section of the ground can be fully mixed with the mopping water and completely adhered by the mopping water.

[0058] Preferably, as a way, the shape of the landing position of the mopping water sprayed from the spray outlet 4 in this embodiment on the forward direction of mopping is a line, the length of the line is 1 to 4 cm, and the starting point of the line is about 2 to 5 cm away from the suction position.

[0059] As Figure 3 shown, it is assumed that the landing position of the mopping water ejected from the ejection port 4 is the line CB in the forward direction of mopping, that is, the landing position of the mopping water at this time is not a single point, but multiple continuous points, and the multiple continuous points fall in the area between point C and point B to form the line CB. Preferably, the length of the line CB of the landing position is 1-4 cm, and the starting point C of the line CB is 2-5 cm away from the suction position A. In this way, the ground between the landing line CB and point A can be completely wetted by the splashed mopping water, and all the large and small impurity particles in this area can be adhered, so as to be completely sucked away subsequently.

[0060] Specifically, referring to Figure 1 and Figure 4 , the main body 1 of the water spraying and dust suction device 100a of this embodiment includes a storage housing 6, a nozzle 7 arranged outside the storage housing 6, and a suction nozzle 8. The suction nozzle 8 is located below the nozzle 7. The ejection port 4 is arranged on the nozzle 7, and the suction port 5 is arranged on the suction nozzle 8. The water spraying module 2 and the water suction module 3 are accommodated in the storage housing 6. In this embodiment, the suction port 5 of the suction nozzle 8 is arranged at the bottom of the suction nozzle 8 facing the ground. The suction port 5 can be vertically facing the ground or at a certain oblique angle to the ground. The suction port 5 is as close to the ground as possible to improve the suction effect.

[0061] A gas-liquid separation structure 9 is arranged at the position where the storage housing 6 is connected to the nozzle 7 and the suction nozzle 8. The gas-liquid separation structure 9 connects the water spraying module 2 with the nozzle 7 and connects the water suction module 3 with the suction nozzle 8. In this implementation, the water outlet pipe 24 of the water spraying module 2 is connected to the gas-liquid separation structure 9, and the suction pipe 33 of the water suction module 3 is connected to the gas-liquid separation structure 9. The gas-liquid separation structure 9 of this embodiment connects the clean water in the storage housing 6 to the nozzle 7 and connects the negative pressure air environment generated in the storage housing 6 to the suction nozzle 8, realizing the gas-liquid separation between the storage housing 6, the nozzle 7 and the suction nozzle 8, so as to realize the discharge of clean water from the clean water tank 21 in the storage housing 6, and the sewage tank 21 sucks and stores the sewage containing ground impurity particles.

[0062] Furthermore, as Figure 5As shown, the gas-liquid separation structure 9 includes a side plate 91 of the receiving housing 6, a gas passage 92 provided on the side plate 91, a water spraying baffle 93 provided above the side plate 91, and a water passage 94 provided on the water spraying baffle 93. In this embodiment, the gas passage 92 is a window opened on the side plate 91, and the gas passage 92 is communicated with the suction pipe 33 of the water absorption module 3. The water spraying baffle 93 is located above the side plate 91, and a tubular water passage 94 is provided on the water spraying baffle 93. One end of the water passage 94 located inside the receiving housing 6 is communicated with the water outlet pipe 24 of the water spraying module 2. The water spraying baffle 93 blocks the sprayed water from flowing back into the receiving housing 6.

[0063] In this embodiment, the side plate 91 and the water spraying baffle 93 on one side of the receiving housing 6 together form the entire side wall of the receiving housing 6. The upper water passage on the side wall realizes outward water spraying, and the lower air passage on the side wall realizes inward adsorption of sewage on the ground, realizing the separation of the gas-liquid flow direction. It can be understood that in other embodiments, the side plate 91 and the water spraying baffle 93 can be an integral structure.

[0064] As Figure 5 and Figure 6 shown, the nozzle 7 includes a first water blocking inclined plate 71 extending outward from the side plate 91 and a second water blocking inclined plate 72 extending outward from the top of the receiving housing 6 and forming an angle with the first water blocking inclined plate 71. The water spraying baffle 93, the first water blocking inclined plate 71, and the second water blocking inclined plate 72 enclose a commutation cavity 70. The suction nozzle 8 is detachably connected to the bottom surface of the first water blocking inclined plate 71, and a plurality of the spray outlets 4 are provided at the front end of the bottom surface of the first water blocking inclined plate 71 at the installation position of the suction nozzle 8.

[0065] In this embodiment, the front ends of the first water blocking inclined plate 71 and the second water blocking inclined plate 72 are both inclined downward and finally intersect together. As Figure 5 shown, a pointed nozzle shape is formed. The spray outlets 4 are opened near the intersection position of the two inclined plates. In this way, the water sprayed by the nozzle 7 is sprayed downward instead of upward, so that the sprayed water can quickly and concentratedly fall onto the ground. The clean mopping water sprayed from the water passage 94 on the water spraying baffle 93 will be sprayed onto the inner walls of the first water blocking inclined plate 71 and the second water blocking inclined plate 72 of the commutation cavity 70 for multiple reflection collisions. After changing the initial water spraying direction, it is sprayed out from the spray outlets 4 at the front end of the first water blocking inclined plate 71 (i.e., the intersection position of the first water blocking inclined plate 71 and the second water blocking inclined plate 72). At the same time, since a plurality of linear spray outlets 4 are spaced apart at the front end of the first water blocking inclined plate 71 of the nozzle 7 in this embodiment, the shape of the mopping water sprayed from the nozzle 7 will also be changed after being sprayed out. Therefore, the nozzle 7 in this embodiment has two functions: one is the water spraying function, and the other is the function of changing the water spraying direction and the water spraying shape.

[0066] The suction nozzle 8 is installed on the bottom surface of the first water baffle 71 of the nozzle 7, and the connection relationship is detachable, so that the installation and disassembly of the suction nozzle 8 in this embodiment are very convenient. It can be understood that in other embodiments, the suction nozzle 8 can be installed on the side plate 91.

[0067] Please continue to refer to Figure 3 , preferably, the angle α between the second water baffle 72 of the nozzle 7 and the horizontal plane is 40 to 90 degrees, so that the mopping water sprayed by the nozzle 7 has a proper landing position on the ground and will not be too far away. Preferably, the α is 45 degrees.

[0068] Furthermore, the angle β between the first water baffle 71 and the second water baffle 72 is 25 to 40 degrees. The size of the angle between the first water baffle 71 and the second water baffle 72 can further control the spraying speed and the landing point. Preferably, the β is 31 degrees.

[0069] As Figure 7 and Figure 8 shown, specifically, the suction nozzle 8 of this embodiment includes a hollow first housing 81 and a second housing 82. An inhalation window 812 for docking with the air passage 92 is provided on the side wall of the first housing 81. The inhalation window 812 is communicated with the air passage 92. The top wall of the first housing 81 is installed on the nozzle 7. In this embodiment, a T-shaped block 811 is provided on the top wall of the first housing 81, and a T-shaped slot 711 is provided on the bottom surface of the first water baffle 71. As Figure 4 and Figure 6 shown, after the T-shaped block 811 is inserted into the T-shaped slot 711, the suction nozzle 8 is installed and fixed to the nozzle 7.

[0070] The second housing 82 is in the shape of a flared mouth with a large upper part and a small lower part. The upper end of the second housing 82 is connected to the first housing 81, and the suction port 5 is provided at the lower end of the second housing 82. The flared mouth shape makes the suction force at the position of the suction port 5 large and it is easy to adsorb impurity particles on the ground.

[0071] Refer to Figure 7 and Figure 8 , the upper end of the first housing 81 is closed, and a first opening 813 is provided at the lower end. An inhalation window 812 is provided on the side wall of the first housing 82. A V-shaped insertion sleeve 83 is further provided at the lower end of the first housing 81, so that the second housing 82 can be inserted and detachably connected to the first housing 81, facilitating the replacement of the second housing 82.

[0072] The upper end of the second housing 82 is provided with a second opening 821, and the lower end is provided with a suction port 5. After the second housing 82 is inserted into the first housing 81 through the insertion sleeve 83, the second opening 821 of the second housing 82 communicates with and is sealed with the first opening 813 of the first housing 81. Preferably, a sealing gasket made of materials such as rubber or silica gel is provided at the edge of the first opening 813 and / or the second opening 821 to ensure the sealing performance. In this way, when the suction nozzle 8 is inserted and installed into the nozzle 7 through the T-shaped block 811 on the top wall of the first housing 81, after the water absorption module 3 is turned on, the mixture of impurity particles and water on the ground enters the second housing 82 from the suction port 5, then enters the first opening 813 of the first housing 81 through the second opening 821 of the second housing 82, then enters the first housing 81, and then enters the suction pipeline 33 from the suction window 812 on the rear side wall of the first housing 81 under the action of suction force, and finally enters the sewage tank 31 for storage.

[0073] In this embodiment, both the first housing 81 and the second housing 82 can be made of plastic material, and the second housing 82 can also be made of silica gel material.

[0074] In this embodiment, the main body 1 further includes a base 10, the storage housing 6 is arranged on the base 10, the base 10 is used to support the storage housing 6, and a connecting rod 12 is also arranged on the base 10. The connecting rod 12 is used to connect the hand-held rod of the electric mop. At the same time, a battery, a control circuit board, etc. can also be arranged inside the connecting rod 12.

[0075] As Figures 1 to 4 , the water spraying and dust suction device 100a of this embodiment further includes a mopping member 11. The mopping member 11 is arranged at the bottom of the base 10 for contacting the ground, and the mopping member 11 is used for mopping the ground to clean the ground. When the water spraying and dust suction device 100a of this embodiment moves in the forward direction of mopping, the nozzle 7 first sprays water on the ground in the forward direction of mopping, then the suction nozzle 8 sucks away the mixture of impurity particles and water on the ground, and then the mopping member 11 wipes the ground to dry the remaining water on the ground. In this embodiment, the mopping member 11 is a cloth piece.

[0076] When the water spraying and dust suction device 100a of this embodiment is in use, the water spraying and adsorption processes and durations are controlled by the program in the control circuit. For example, during the forward movement, at the initial start, after spraying water, adsorption starts after a preset delay time, and then during the entire forward movement, water is sprayed and adsorbed simultaneously. Then when moving backward, the water spraying and adsorption are turned off, and only the mopping member 11 dries the ground.

[0077] The water spraying and dust suction device 100a of this embodiment adopts a mopping method of first wet-sucking impurity particles and then using the mopping member 11 to mop the ground, which greatly improves the cleaning effect of the ground.

[0078] Embodiment 2, as Figure 9As shown, this embodiment provides a water spraying and dust suction device 100b for an electric mop, which is different from the first embodiment in that the floor wiping member 11 of the second embodiment is two rotating disks installed at the bottom of the base 10, and the rotating disks rotate to wipe the floor. Correspondingly, a rotating driving member (not shown) is provided in the base 10 of the second embodiment, which is connected to the rotating disk to drive the rotating disk to rotate, and the rotating driving member can adopt a structure in the prior art, such as a motor combined with a gear transmission rotation structure.

[0079] Embodiment three, as Figure 10 As shown, this embodiment provides a water spraying and dust suction device 100c for an electric mop, which is different from the first embodiment in that the floor wiping component 11 of the third embodiment is also a turntable, and the storage shell 6 of the third embodiment is located above the base 10 and can rotate relative to the base 10. In this way, when simply wiping the floor without the water spraying and adsorption function, the storage shell 6 and its components and the nozzle 7 and the suction nozzle 8 can be turned up as a whole, and only the turntable is used for wiping the floor. When the water spraying and adsorption function is required, the storage shell 6 can be turned down as a whole to cover the base 10. In this embodiment, the storage shell 6 can be rotatably connected to the base 10, or rotatably connected to the connecting rod 12.

[0080] like Figure 11 As shown, this embodiment also proposes an electric mop 200, including the water spray dust suction device 100a, 100b, 100c as described above, and also including a hand-held rod 201 connected to the dust suction device. The hand-held rod 201 is connected to the connecting rod 12 of the dust suction device. Preferably, the connecting rod 12 is rotatably connected to the base 10. Further, the electric mop 200 of this embodiment can be a cordless electric mop, that is, a built-in driving battery, and no external power cord is required when in use.

[0081] Since the electric mop 200 of the present embodiment has the above-mentioned water spraying and dust suction devices 100a, 100b, 100c, it has the beneficial effects of the above-mentioned water spraying and dust suction devices, which will not be described one by one here.

[0082] The above description is only an example to clearly illustrate the present invention, and does not limit the patent scope of the present invention. It is impossible to list all implementation methods here. All equivalent structural changes made by using the contents of the technical solution of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
