The wastewater tank is configured to store wastewater generated during the cleaning process.

The cleaning apparatus of the present disclosure includes a heating device and a spray head assembly, wherein the heating device is configured to heat water to generate a mist. The spray head assembly is provided with at least one air jet hole, the air jet hole comprises a vortex section and a spray section which are communicated with each other, and water mist generated by the heating device is configured to be sprayed out through the vortex section and the spray section in sequence.

The blocking surface used for reflecting the air flow is arranged in the vortex section, so that when the cleaning equipment works and generates water mist, the water mist generated by the heating device is sprayed out through the air spraying holes, and as the blocking surface used for reflecting the air flow is arranged in the vortex section, part of the water mist can be sprayed to the blocking surface and reflected back, and after the vortex is formed in the vortex section, the water mist can be sprayed out from the spraying section under the driving of the air flow. In the process, part of the water mist forms vortex in the vortex section, so that the water mist can generate loud sound, the loud sound can be heard by a user, and the user can know that the cleaning equipment is in a state of normally spraying the water mist. When the user does not hear the sound generated by the vortex, the cleaning device can be determined to be in a non-water mist starting mode or the device is in fault, so that the cleaning device can be overhauled in time.

For ease of understanding, the specific structure of the cleaning apparatus and spray head assembly of the present disclosure and its principles of operation are described in detail below in connection with one embodiment with reference to fig. 1-14.

As shown in fig. 1, the present disclosure provides a cleaning apparatus that may include a main body 30, a heating device (not shown), and a spray head assembly 10. Wherein the heating means is configured to heat water to generate a mist 2, which may be a heating boiler or other form of construction, as long as it is capable of heating water and forming mist 2. In the embodiment of the disclosure, the water mist 2 may refer to high-temperature steam, and when cleaning work is performed, the working surface is preheated by the high-temperature steam, so that dirt on the working surface can be softened, and the dirt on the working surface is removed.

It can be understood that the cleaning device may also be provided with a water cleaning barrel 50 and a driving pump, the driving pump pumps water in the water cleaning barrel 50 into a heating device, then the heating device heats the water and generates high-temperature water mist, and the high Wen Shuiwu can be sprayed out of the spray head assembly 10 after passing through corresponding pipelines; the cleaning apparatus may also include a waste tank 50 for containing waste water on the work surface.

The spray head assembly 10 may be provided on the floor brush assembly 60 of the cleaning apparatus and at least one air jet hole 1 is provided, and each air jet hole 1 communicates with an air outlet of the heating device. Specifically, as shown in fig. 1 and 2, the air injection hole 1 includes a swirl section 11 and an injection section 12 which are communicated with each other, and the water mist 2 generated by the heating device is configured to be injected sequentially through the swirl section 11 and the injection section 12, wherein a blocking surface 111 for reflecting the air flow is provided in the swirl section 11.

As shown in fig. 2, according to fluid simulation and actual use results, in the cleaning device of the present disclosure, since the blocking surface 111 for reflecting the air flow is provided in the vortex section 11, when the air flow is sprayed outwards through the vortex section 11 and the spraying section 12, part of the water mist 2 can strike the blocking surface 111 of the vortex section 11 and be reflected back by the blocking surface 111 to form a reverse flowing air flow vortex, after the air flow vortex moves to the central part of the vortex section 11, the air flow is sprayed from the spraying section 12 under the driving of most of the air flow, and during the movement, the water mist 2 forms a vortex in the vortex section 11, so that the water mist 2 can emit audible sound of human ears in the vortex section 11. In the conventional cleaning apparatus, however, referring to fig. 3, since the inner diameter of the air jet holes 1 is uniform throughout, the water mist 2 cannot form a vortex, and cannot emit audible sound to the human ear.

In particular, there are at least three reasons for the water mist 2 to be able to emit audible sound to the human ear. As soon as the air flow swirls, sound waves are formed and propagate outwards. Secondly, the air flow can impact the blocking surface 111 in the process of vortex rotation, so that the hole wall where the blocking surface 111 is located vibrates, and the hole wall where the blocking surface 111 is located generates sound. Thirdly, in the process that the water mist 2 moves towards the direction of the spraying section 12 and is sprayed out after moving to the central part of the vortex section 11 along the vortex, the air flow pressure of the water mist 2 can generate obvious jump, and in the process of pressure jump, the water mist 2 can vibrate, so that sound waves can be generated. When at least part of the sound waves generated in the process are in the range of audible frequencies of human ears (namely 20Hz to 20000 Hz), the user can hear the sound, so that the water mist 2 is sprayed from the air spraying holes 1. It can be seen that the swirl is an important factor in generating sound and that the formation of the swirl is in great relation to the arrangement of the blocking surface 111.

In one embodiment of the present disclosure, as shown in fig. 2, the discharge section 12 and the scroll section 11 are respectively cylindrical holes, and the inner diameter of the discharge section 12 is smaller than the inner diameter of the scroll section 11, and the blocking surface 111 is a step surface formed at the connection position of the discharge section 12 and the scroll section 11. That is, the ejection segment 12 extends in a straight direction, and the dimensions of any position thereof are the same. Similarly, the scroll section 11 extends in a straight direction, and the dimensions of any position thereof are the same. Since the inner diameter of the discharge section 12 is smaller than the inner diameter of the scroll section 11, the two inner diameters are different, and thus a stepped surface, which is the above-described blocking surface 111, is formed at the connection position of the discharge section 12 and the scroll section 11.

Referring to fig. 2, when the air flow is ejected from the air ejection hole 1, the air flow passes through the swirl section 11 and the ejection section 12 in this order, and the air flow is fastest in the extending direction of the ejection section 12, i.e., the air flow is concentrated in the extending direction of the ejection section 12, because the inner diameter size of the ejection section 12 is small. However, because the inner diameter of the vortex section 11 is larger, most of the airflow is directly sprayed out from the spraying section 12 after passing through the vortex section 11, and part of the airflow can strike the step surface formed at the connection position of the spraying section 12 and the vortex section 11 in the process of flowing through the vortex section 11, so that the airflow reversely flows under the reflection action of the step surface, and the airflow vortex is formed, and a larger sound is further generated. The swirling flow is induced during the flow by the air flow in the main flow direction to be ejected through the ejection section 12.

In another embodiment of the present disclosure, as shown in fig. 4, the scroll section 11 has a frustum shape, and opposite ends thereof are respectively denoted as a first end and a second end having an inner diameter larger than that of the first end, wherein the spouting section 12 is configured to be connected to the first end of the scroll section 11, and the blocking surface 111 is an inclined inner wall of the scroll section 11. Referring to the view direction of fig. 4, the inner diameter of the scroll section 11 gradually decreases from bottom to top and finally connects with the discharge section 12, which causes the inner wall of the scroll section 11 to gradually extend from bottom to top toward the central axis thereof, thereby forming a gradually inclined blocking surface 111.

Because the inclined inner wall is arranged in the vortex section 11, part of the water mist 2 can be blocked by the inclined inner wall in the rapid spraying process, so that a certain degree of vortex is formed, sound is generated, and the specific sound generation principle is the same as that of the embodiment shown in fig. 2, and the disclosure is not specifically described herein.

According to the cleaning equipment disclosed by the disclosure, in the working process, after the water mist 2 generated by the heating device reaches the vortex section 11 of the air spraying hole 1, the blocking surface 111 for reflecting air flow is arranged in the vortex section 11, the water mist 2 can form vortex in the vortex section 11 and then is sprayed out from the spraying section 12, and in the process, the water mist 2 can generate larger sound so as to be heard by a user, and the user can know that the cleaning equipment normally sprays the water mist 2, so that the use experience of the user is improved. When the user does not hear the sound generated by the vortex, the cleaning device can be determined to be in a non-water mist starting mode or the device is in fault, so that the cleaning device can be overhauled in time.

As shown in fig. 2, in the case where the foregoing discharge section 12 and the swirl section 11 are cylindrical holes, in one embodiment of the present disclosure, the discharge section 12 is disposed coaxially with the swirl section 11, so that the water mist 2 entering the swirl section 11 from all directions in the circumferential direction can form a large degree of swirl, thereby increasing the sound emitted from the water mist 2.

Whether or not the airflow can form a vortex of the airflow in the vortex section 11, or the degree of the vortex is formed is related to the sizes of the vortex section 11 and the ejection section 12. In one embodiment of the present disclosure, the inner diameter of the swirl section 11 is 1.5mm to 3.5mm and the inner diameter of the discharge section 12 is 1mm to 1.5mm. Under the condition that the inner diameter of the spraying section 12 is 1mm to 1.5mm, the processing difficulty of the spraying section 12 can be effectively reduced, and the condition that the flow velocity of the water mist 2 is reduced and the visual effect and the hearing effect of the water mist 2 are greatly reduced due to the overlarge inner diameter of the spraying section 12 is avoided. As shown in fig. 8 and 9, the percentage of vortex formation of the water mist 2 was increased from 5% to about 55% continuously in the course that the inner diameter of the discharge section 12 was 1mm and the axial length of the vortex section 11 was 3mm, and the inner diameter of the discharge section 12 was changed from 1.5mm to 3.5 mm. While the swirling percentage of the water mist 2 is continuously increased from 5% to about 42% during the course of the change of the inner diameter of the swirling section 11 from 1.5 to 2.5mm, and is continuously decreased from 42% to about 20% during the course of the change of the inner diameter of the swirling section 11 from 2.5 to 3.5 mm. The vortex forming percentage is the ratio of the formed vortex angle of the water mist 2 in the expanding section to the whole circle, and the vortex percentage is the percentage of the water mist 2 participating in forming the vortex accounting for all the water mist 2.

Specifically, as shown in fig. 5, when the inner diameter of the vortex section 11 is 1.5mm, the space for forming the vortex is relatively small, and the water mist participating in forming the vortex is relatively small; as shown in fig. 6, at an inner diameter of the swirl section 11 of 2.5mm, the space is enough to form a swirl, and the air flow participating in the formation of the swirl is increased and a very complete swirl is formed; as shown in fig. 6, when the inner diameter of the swirl section 11 is 3.5mm, the space is too large, the water mist is weak to form a complete swirl, and although more water mist participates in forming the swirl, the viewing effect of the water mist is reduced because the water mist does not form the complete swirl.

In summary, when the inner diameter of the vortex section 11 is 1.5mm to 3.5mm and the inner diameter of the spraying section 12 is 1mm to 1.5mm, the ratio of the vortex angle formed by the water mist 2 in the expanding section to the whole circle is high, and the percentage of the water mist 2 participating in forming the vortex is also high, so that more water mist 2 can form a vortex with a larger angle, and the sound emitted by the water mist 2 is improved.

In one embodiment of the present disclosure, as shown in fig. 6, 8 and 9, when the inner diameter of the spraying section 12 is 1mm and the inner diameter of the spraying section 12 is 2.5mm, the percentage of vortex formation of the water mist 2 is 40% and the percentage of vortex is 42%, so that the percentage of the water mist 2 participating in forming the vortex is maximum, and the formed vortex angle of the water mist 2 in the expanding section is also relatively large, so that the sound emitted by the water mist 2 is loud.

Whereas for the axial length of the scroll section 11, in one embodiment of the present disclosure, the axial length of the scroll section 11 is 1.5mm to 4.5mm. As shown in fig. 13 and 14, in the process that the inner diameter of the discharge section 12 is 1mm, the inner diameter of the scroll section 11 is 2.5mm, and the axial length of the scroll section 11 is 1.5mm to 4.5mm, the percentage of vortex formation and the percentage of vortex of the water mist 2 are increased continuously, the percentage of vortex formation is increased from 30% to 100%, and the percentage of vortex is increased from 5% to 40%.

Specifically, as shown in fig. 10, when the axial length of the vortex section 11 is 1.5mm, the space for forming the vortex is relatively small, the water mist flows out of the air nozzle without forming the vortex, and the water mist participating in forming the vortex is relatively small; as shown in fig. 11, when the axial length of the vortex section 11 is 3mm, the axial space is enough for the water mist to form a complete vortex, more vortex water mist is formed, and a complete vortex is formed; as shown in fig. 12, at an axial length of 4.5mm of the swirl section 11, the swirl is still complete and the percentage of the swirl involved is also substantially unchanged, but the step Kong Guochang causes the steam to cool, reducing the visual effect of the steam blow-out. Due to the excessively long axial length of the swirl section 11, part of the water mist 2 is cooled, and the visual effect of the water mist 2 is reduced.

In summary, under the condition that the axial length of the vortex section 11 is 1.5mm to 4.5mm, the ratio of the vortex angle formed by the water mist 2 in the expanding section to the whole circle is higher, and the percentage of the water mist 2 participating in forming the vortex is also higher, so that more water mist 2 can form a vortex with a larger angle, and the sound emitted by the water mist 2 is improved. And when the axial length of the vortex section 11 is 3mm, the visual effect and the auditory effect of the water mist 2 are good, so that the visual effect of the water mist 2 is effectively improved.

In one embodiment of the present disclosure, the flow rate of the spraying section 12 is 0.67g to 1g/min, that is, the mass of the water mist 2 sprayed by each spraying section 12 in each minute is 0.67g to 1g, so that the sufficient flow rate of the water mist 2 can be maintained at the position of the spraying hole 1, thereby forming a sufficient vortex, ensuring the visual effect of the water mist 2, and avoiding the excessive flow rate of the water mist 2, but making the water content of the water mist larger to wet the working surface to be cleaned.

Similarly, in one embodiment of the present disclosure, the temperature of the water mist 2 at the air injection holes 1 is maintained at 95 ℃ to 102 ℃, so that the cleaning effect of the water mist 2 can be effectively improved, and the working surface to be cleaned is not damaged due to the too high temperature.

The present disclosure further provides a showerhead assembly 10, and the structure and effects of the showerhead assembly 10 are referred to above and will not be described herein. The spray head assembly 10 of the present disclosure may be applied not only to the cleaning apparatus described above, but also to other apparatuses that require water mist delivery, such as eye fumigators, garment hangers, and the like, as will not be described in detail herein.

The blocking surface 111 is a step surface formed at the connection position of the spraying section 12 and the vortex section 11, so that the water mist 2 is blocked by the step surface after entering the vortex section 11, and the space in the vortex section 11 is larger, so that a larger vortex is formed, and a larger sound is emitted, so that the water mist can be heard by a user, the user can know that the cleaning device normally sprays the water mist 2, and the use experience of the user is improved; when the cleaning equipment does not normally spray out the water mist 2 and can not make a sound, a user can also find the water mist in time and overhaul the cleaning equipment.
