Description

Technical Field

[0001] The invention relates to a cleaning machine. Background Art

[0002] With the development of technology, a vacuum cleaner has been combined with a conventional mop to create a vacuum cleaner that can be used to mop and wash the floor. This machine can then recycle the water after it discharges water. Since the vacuum cleaner has the process of discharging water, mopping and washing, and then recycling water, vacuum cleaners are currently designed to suck in particles and water. Therefore, most vacuum cleaners on the market only have a water scraper on one side of the forward direction, such as a water scraper behind the suction port of a vacuum cleaner.

[0003] Since the cleaning machine is only provided with a wiper strip on one side of the suction port, such as behind the roller brush, the following problem exists: the moving direction of the vacuum cleaner is restricted, and the vacuum cleaner can only move forward. Only when it moves forward can the vacuum cleaner absorb particles and water, and when the vacuum cleaner is pulled backward, the strip prevents the suction port of the vacuum cleaner from absorbing water and particles. If the strip is removed, the strip cannot be used to collect water and particles, resulting in poor absorption of particles and water by the vacuum cleaner. Therefore, regardless of whether there is a wiper strip, the vacuum cleaner cannot take into account the dilemma of both suction effect and dust suction direction restriction. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a cleaning machine in order to overcome the defect of poor absorption effect of the cleaning machine in the prior art.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A wind power device includes a ventilation duct and a drive system, wherein the drive system is arranged on the ventilation duct, and the drive system is used to provide power for the ventilation duct to inhale and discharge external substances. The ventilation duct includes an air inlet duct and an air outlet duct, and at least one air outlet of the air outlet duct is arranged in a horizontal direction close to and toward the air inlet of the air inlet duct.

[0007] In this solution, compared with the previous technology, this structural form is adopted, at least one outlet of the air outlet pipeline is arranged near the air inlet of the air inlet pipeline, and is arranged toward the air inlet of the air inlet pipeline, so as to use the gas generated by the drive system to blow foreign matter into the air inlet of the air inlet pipeline. The structure is simple and compact, and it is easy to improve the ability of the air inlet pipeline to absorb foreign matter, thereby improving the suction effect of the wind power device. At the same time, the inhaled gas is recycled to improve the gas utilization rate, and while achieving energy saving and emission reduction, the working efficiency of the entire wind power device is maximized.

[0008] Preferably, the air outlet of the air outlet duct is inclined toward the air inlet of the air inlet duct, and the inclination angle of the air outlet of the air outlet duct relative to the horizontal plane is in the range of 30°-60°.

[0009] In the present scheme, the above-mentioned structural form is adopted to quantify the inclination angle of the air outlet of the first air outlet section, so as to improve the effect of the air outlet of the first air outlet section on blowing foreign matter within the range into the air inlet of the air inlet duct, and also improve the specificity of the air outlet of the first air outlet section in blowing gas into the air inlet duct, while increasing the air outlet area of ​​the air outlet of the first air outlet section, thereby reducing the difficulty of foreign matter entering the air inlet duct.

[0010] Preferably, the air outlet duct includes a first air outlet section, and the drive system includes a first drive system. The starting end of the first air outlet section along the air flow direction is connected to the air outlet end of the first drive system, and the end of the first air outlet section along the air flow direction is arranged close to and toward the air inlet of the air inlet duct.

[0011] In the present scheme, this structural form is adopted to limit the part of the air outlet duct close to the air inlet of the air inlet duct, and define this part as the first air outlet section, and further define the positional relationship and connection relationship between the first air outlet section and the first drive system and the air inlet of the air inlet duct. This can enhance the driving force provided by the corresponding part of the air outlet duct, i.e., the first air outlet section, to the air inlet of the air inlet duct, improve the specificity of the air outlet of the first air outlet section to blow gas into the air inlet duct, and thereby reduce the difficulty of foreign matter entering the air inlet duct.

[0012] Preferably, the number of the air outlets of the first air outlet section is two, and the two air outlets of the first air outlet section are symmetrically arranged on both sides of the air inlet of the air inlet duct.

[0013] In this solution, the above-mentioned structural form is adopted, and the air outlets of the two first air outlet sections are symmetrically arranged relative to the air inlet of the air inlet duct, which greatly improves the efficiency of the air inlet duct in sucking in external substances, and also expands the suction range of the air inlet duct, making the operation of the wind power device more flexible and centralized.

[0014] Preferably, the width of the air outlet of the first air outlet section is equal to the width of the air inlet of the air inlet duct.

[0015] In the present scheme, the above-mentioned structural form is adopted, and the width of the air outlet of the first air outlet section and the air inlet of the air inlet duct are set to be the same, so as to improve the consistency and pertinence of the air inlet duct with the first air outlet section during suction, that is, when the air outlet of the first air outlet section blows out the gas within a specific width range, the part of the gas is blown in a targeted manner to the air inlet of the air inlet duct corresponding to the width of the air outlet of the first air outlet section, which can greatly improve the efficiency of the air inlet duct in sucking in external substances.

[0016] Preferably, along the horizontal direction, the horizontal distance from the air outlet of the first air outlet section to the air inlet of the air inlet duct is in the range of 15 mm-25 mm.

[0017] In this solution, the above-mentioned structural form is adopted to shorten the distance between the air outlet of the first air outlet section and the air inlet of the air inlet duct, which can enhance its suction capacity and blowing force while realizing the air inlet duct to suck in external substances, thereby significantly improving the suction efficiency.

[0018] Preferably, the pressure of the air outlet pipeline is greater than the pressure of the air inlet pipeline.

[0019] In the present scheme, the above-mentioned structural form is adopted to better discharge the gas from the first air outlet section and form a continuous power through the discharged gas, thereby increasing the pressure of the first drive system in the air outlet duct, facilitating the air inlet of the air inlet duct to better absorb foreign matter, and also improving the suction and discharge capacity of the wind power device.

[0020] Preferably, the air outlet duct includes a second air outlet section, the starting end of the second air outlet section along the air flow direction is connected to the air outlet end of the first drive system, the end of the second air outlet section along the air flow direction is directly connected to the outside, the second air outlet section is arranged away from the air inlet, and the end of the first air outlet section close to the first drive system is partially connected to the end of the second air outlet section close to the first drive system.

[0021] In this solution, the above structural form is adopted to improve the utilization rate of gas. At the same time, it is convenient for the wind power device to be applied to the existing technology, and the flexibility and extensiveness of the use of the wind power device are improved.

[0022] Preferably, the drive system also includes a second drive system, the air inlet end of the second drive system is connected to the air outlet end of the first drive system, the air outlet end of the second drive system is connected to the starting end of the first air outlet section, and the second drive system is used to inhale the gas generated by the first drive system and discharge the gas from the air outlet of the first air outlet section after passing through the second drive system.

[0023] In this solution, the above structural form is adopted to improve the utilization rate of gas. The first drive system and the second drive system are distinguished and operated independently. This arrangement facilitates the wind power device to be applicable to existing technologies and improves the flexibility and extensiveness of the use of the wind power device. At the same time, it avoids using a single drive type device that causes a high drive temperature and reduces the service life.

[0024] Preferably, the air outlet duct also includes a second air outlet section and a connecting section, one end of the second air outlet section is connected to one end of the connecting section, the other end of the second air outlet section is connected to the outside, and the other end of the connecting section is connected to the second drive system, and the second drive system absorbs another part of the gas generated by the first drive system through the connecting section and discharges it from the first air outlet section through the second drive system.

[0025] In the present solution, the above-mentioned structural form is adopted to improve the utilization rate of gas. The second drive system is distinguished from the first drive system so that they can operate independently, avoiding the use of a drive-type device that makes the drive temperature high and reduces the service life. At the same time, a separate second drive system is set on the first air outlet section, which shortens the distance that the gas flows from the blower to the suction port, enhances the running power of the gas, that is, the driving force, improves the suction capacity and strength of the air inlet of the air inlet pipeline, and enhances its absorption rate. Such a setting facilitates the wind power device to be applicable to the existing technology and improves the flexibility and extensiveness of the use of the wind power device. Furthermore, a second air outlet section is independently set up to discharge a part of the gas generated by the first drive system from the second air outlet section. Such a setting facilitates the wind power device to be applicable to the existing technology.

[0027] In the present solution, the above-mentioned structural form is adopted to improve the utilization rate of gas. The second drive system is distinguished from the first drive system so that they can operate independently, avoiding the use of a drive-type device that makes the drive temperature high and reduces the service life. At the same time, a separate second drive system is set on the first air outlet section, which shortens the distance that the gas flows from the blower to the suction port, enhances the running power of the gas, that is, the driving force, improves the suction capacity and strength of the air inlet of the air inlet pipeline, and enhances its absorption rate. Such a setting facilitates the wind power device to be applicable to the existing technology and improves the flexibility and extensiveness of the use of the wind power device.

[0054] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0055] Example 1

[0056] like Figure 1-2 As shown, this embodiment discloses a wind power device 100 .

[0057] The wind power device 100 includes a ventilation duct 200 and a drive system 300. The ventilation duct 200 and the drive system 300 are connected, and the drive system 300 is arranged on the ventilation duct 200. The function of the drive system 300 is to provide power to the ventilation duct 200 to facilitate the ventilation duct 200 to inhale and discharge external substances.

[0058] The drive system 300 is arranged in the middle of the ventilation pipeline 200, and the ventilation pipeline 200 is divided into an air inlet pipeline 21 and an air outlet pipeline 22. The air outlet of at least one air outlet pipeline 22 is arranged close to and toward the air inlet 211 of the air inlet pipeline. The gas generated by the drive system 300 is used to blow foreign substances into the air inlet 211 of the air inlet pipeline. With this structural form, the structure is simple and compact, and it is easy to improve the ability of the air inlet pipeline 21 to absorb foreign substances, thereby improving the suction effect of the wind power device 100. At the same time, the inhaled gas is recycled to improve the gas utilization rate, and while achieving energy saving and emission reduction, the working efficiency of the entire wind power device 100 is also maximized.

[0059] The air outlet duct 22 includes a first air outlet section 221, the drive system 300 includes a first drive system 31, one end of the first air outlet section 221 is connected to the air outlet end 311 of the first drive system, and the other end of the first air outlet section 221 is close to and faces the air inlet 211 of the air inlet duct. With this structural form, the part of the air outlet duct 22 close to the air inlet 211 is defined, and the part is defined as the first air outlet section 221, and the positional relationship and connection relationship between the first air outlet section 221, the first drive system 31 and the air inlet 211 of the air inlet duct are further defined, which can enhance the driving force provided by the corresponding part of the air outlet duct 22, i.e., the first air outlet section 221, to the air inlet 211 of the air inlet duct, improve the pertinence of the air outlet 2211 of the first air outlet section to blow gas into the air inlet duct 21, and thus reduce the difficulty of foreign matter entering the air inlet duct 21.

[0060] In this embodiment, the number of the air inlet pipeline 21 is one, the number of the first air outlet sections 221 is two, and the two first air outlet sections 221 are symmetrically arranged on both sides of the air inlet 211 of the air inlet pipeline, which can greatly improve the efficiency of the air inlet pipeline 21 sucking in foreign substances, and also expand the suction range of the air inlet pipeline 21, making the wind power device 100 work more flexible. In other embodiments, the number of air inlet pipelines 21 and air outlet pipelines 22 can be set as needed, as long as the foreign substances are blown into the air inlet pipeline 21 through the air outlet 2211 of the first air outlet section.

[0061] like Figure 2 As shown, the air outlet 2211 of the first air outlet section is tilted toward the air inlet 211 of the air inlet pipeline, and the tilt angle θ of the air outlet 2211 of the first air outlet section relative to the horizontal plane is controlled within the range of 30°-60°. Quantifying the tilt angle of the air outlet 2211 of the first air outlet section facilitates improving the effect of the air outlet 2211 of the first air outlet section on blowing foreign substances within the range into the air inlet 211 of the air inlet pipeline, and also improves the pertinence of the air outlet 2211 of the first air outlet section in blowing gas into the air inlet pipeline 21, while increasing the air outlet area of ​​the air outlet 2211 of the first air outlet section, thereby reducing the difficulty of foreign substances entering the air inlet pipeline 21.

[0062] Specifically, in this embodiment, the width of the air inlet of the first air outlet section 221 is the same as the width of the air outlet of the air outlet duct 22, which can facilitate improving the consistency and pertinence of the air inlet duct 21 with the first air outlet section 221 during inhalation, that is, when the air outlet 2211 of the first air outlet section blows out gas within a specific width range, the gas is blown to the air inlet 211 of the air inlet duct corresponding to the width of the air outlet 2211 of the first air outlet section in a targeted manner, which can greatly improve the efficiency of the air inlet duct 21 inhaling external substances. The specific inclination angle θ of the air outlet 2211 of the first air outlet section can be selected according to actual conditions, for example, it can be set as needed according to the size of the internal space of the component and the connection form with other components.

[0063] The distance between the air outlet 2211 of the first air outlet section and the air inlet 211 of the air inlet duct is 15 mm-25 mm. In this embodiment, the distance is preferably 20 mm. With the above structure, compared with the air outlet 2211 of the first air outlet section and the air inlet 211 of the air inlet duct being at a longer distance, the distance between the air outlet 2211 of the first air outlet section and the air inlet 211 of the air inlet duct is shortened, and the air inlet duct 21 can be inhaled by the external substances while enhancing its inhalation capacity, so that the inhalation efficiency can be significantly improved.

[0064] At the same time, in order to better discharge the gas from the first air outlet section 221 and form a continuous power through the discharged gas, the pressure of the first drive system 31 in the air outlet duct 22 is increased, so that the air inlet 211 of the air inlet duct can better absorb foreign substances, and the suction and discharge capacity of the wind power device 100 can also be improved. Specifically, in order to achieve the purpose of making the pressure of the air outlet duct 22 greater than the pressure of the air inlet duct 21, the following methods can be adopted: by respectively adjusting the pressure of the drive system 300 in the air inlet duct 21 and the air outlet duct 22 and changing the pipe thickness and length of the air inlet duct 21 and the air outlet duct 22.

[0065] This embodiment also discloses a specific implementation of a cleaning machine, which adopts the wind power device 100 shown in this embodiment.

[0067] like Figure 3 As shown, Embodiment 2 discloses another wind power device 100. The structure of Embodiment 2 is substantially the same as that of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that:

[0068] The air outlet duct 22 includes a second air outlet section 222, wherein one end of the second air outlet section 222 is connected to the air outlet end 311 of the first drive system, the other end of the second air outlet section 222 is connected to the outside, and one end of the first air outlet section 221 close to the first drive system 31 and one end of the second air outlet section 222 close to the first drive system 31 are partially connected.

[0069] In this embodiment, the above structure is adopted to improve the utilization rate of gas and at the same time, the wind power device 100 is easy to apply to the existing technology, thereby improving the flexibility and wide application of the wind power device 100.

[0073] The drive system 300 also includes a second drive system 32, which exists independently of the first drive system 31. The air inlet end 321 of the second drive system is connected to the air outlet end 311 of the first drive system, and the other end of the second drive system 32 is connected to the first air outlet section 221. The second drive system 32 is used to inhale the gas generated by the first drive system 31 and discharge the gas from the air outlet 2211 of the first air outlet section after passing through the second drive system 32.

[0074] In this embodiment, the above-mentioned structure is adopted to distinguish the first drive system 31 and the second drive system 32 so that they can operate independently. This arrangement facilitates the wind power device 100 to be applicable to the existing technology and improves the flexibility and extensiveness of the use of the wind power device 100. At the same time, it avoids using a single drive type device to make the drive temperature high and reduce the service life.

[0077] The air outlet duct 2 also includes a second air outlet section 222 and a connecting section 23. One end of the second air outlet section 222 is connected to one end of the connecting section 23, and the other end of the second air outlet section 222 is connected to the outside. The other end of the connecting section 23 is connected to the second drive system 32. The second drive system 32 absorbs another part of the gas generated by the first drive system 31 through the connecting section 23, and then discharges it from the first air outlet section 221 through the second drive system 32.

[0078] In this embodiment, the above-mentioned structural form is adopted to improve the utilization rate of gas. The second drive system 32 and the first drive system 31 are distinguished so that they can operate independently, avoiding the use of a drive-type device that makes the drive temperature high and reduces the service life. At the same time, a separate second drive system 32 is set on the first air outlet section 221, which shortens the distance that the gas flows from the blower to the suction port, enhances the running power of the gas, that is, the driving force, and improves the suction capacity and strength of the air inlet 211 of the air inlet pipeline, enhances its absorption rate, and such a setting facilitates the wind power device 100 to be applicable to the existing technology, and improves the flexibility and extensiveness of the use of the wind power device 100. Furthermore, a second air outlet section 222 is independently set to discharge a part of the gas generated by the first drive system 31 from the second air outlet section 222, and such a setting facilitates the wind power device 100 to be applicable to the existing technology.

[0079] This embodiment also discloses a specific implementation of a cleaning machine, which adopts the wind power device 100 shown in this embodiment.

The second drive system 32 and the first drive system 31 are distinguished so that they can operate independently, avoiding the use of a drive-type device that makes the drive temperature high and reduces the service life. At the same time, a separate second drive system 32 is set on the first air outlet section 221, which shortens the distance that the gas flows from the blower to the suction port, enhances the running power of the gas, that is, the driving force, and improves the suction capacity and strength of the air inlet 211 of the air inlet pipeline, enhances its absorption rate, and such a setting facilitates the wind power device 100 to be applicable to the existing technology, and improves the flexibility and extensiveness of the use of the wind power device 100. Furthermore, a second air outlet section 222 is independently set to discharge a part of the gas generated by the first drive system 31 from the second air outlet section 222, and such a setting facilitates the wind power device 100 to be applicable to the existing technology.

[0084] This embodiment also discloses a specific implementation of a cleaning machine, which adopts the wind power device 100 shown in this embodiment.

[0085] Example 6

[0088] With this structural form, the air outlet of the cleaning machine replaces the rubber strip in the original technology, and there is no need to set a rubber strip at the air inlet, so as to avoid the setting of the rubber strip hindering the intake of foreign matter such as dust and water.

[0089] At the same time, by arranging air outlets on both sides and using the inclined air outlets to collect dust and water on the corresponding sides, the cleaning machine has the ability to move back and forth (i.e., move forward and backward) at the same time to clean the floor, and will not be able to clean the floor in only one direction due to the presence of the rubber strip.
