Description

Technical Field

[0001] The present application relates to the technical field of dust removal equipment, and in particular to a dust and gas separation device and a dust collector. Background Art

[0002] As a cleaning device, the working principle of a vacuum cleaner is generally to use a motor to drive the fan to rotate at high speed to form an airflow, thereby forming a negative pressure in the vacuum cleaner shell, so that dust in the environment is sucked into the shell through the air inlet at one end of the shell, and clean air is discharged from the air outlet at the other end of the shell, thereby cleaning the environment.

[0003] However, after the existing vacuum cleaners suck in the dust gas, the air and dust in the dust gas are usually separated under the centrifugal effect of the high-speed airflow rotation, the light air enters the filter screen and other filtering devices, and the heavy dust settles in the dust collecting chamber. Due to the light weight of the dust, the dust settling effect is not good, resulting in poor air-dust separation effect of the dust gas. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the utility model, not all the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0026] With the development of science and technology, more and more cleaning equipment have gradually replaced traditional brooms and mops. Among them, vacuum cleaners are a kind of cleaning equipment. Their working principle is generally to use a motor to drive the fan to rotate at high speed to form an airflow, thereby forming a negative pressure in the shell of the vacuum cleaner, so that the dust in the environment is sucked into the shell through the air inlet at one end of the shell, and the clean air is discharged from the air outlet at the other end of the shell, thereby cleaning the environment.

[0027] However, after the existing vacuum cleaners suck in the dust gas, the air and dust in the dust gas are usually separated under the centrifugal effect of the high-speed airflow rotation, the light air enters the filter screen and other filtering devices, and the heavy dust settles in the dust collecting chamber. Due to the light weight of the dust, the dust settling effect is not good, resulting in poor air-dust separation effect of the dust gas.

[0028] Based on the above questions, please refer to Figure 1 The embodiment of the present application provides a vacuum cleaner, which is used to absorb dust and separate dust from air, and deposit the dust in a dust collecting chamber to achieve a cleaning effect. It can be understood that dust refers to a mixture of dust and air, and the embodiment of the present application does not specifically limit dust. For example, powder, particles, etc. are dust in the embodiment of the present application.

[0029] For details, please also refer to Figure 1 and Figure 2 The vacuum cleaner 1 provided in the embodiment of the present application includes: a dust and gas separation device 10, a driving device 400 and a power supply device 500, the power supply device 500 is electrically connected to the driving device 400 and the power supply device 500 is electrically connected to the dust and gas separation device 10.

[0030] Please also see Figure 3 and Figure 4 The dust and gas separation device 10 includes a shell 100 and an atomization device 200. The shell 100 has an installation cavity 130, and the installation cavity 130 can filter dust and gas.

[0031] In this embodiment, the atomizing device 200 includes an atomizing assembly 210 and a liquid tank 220. The atomizing assembly 210 can spray mist into the installation cavity 130, and the liquid tank 220 can store liquid to be atomized, such as water, cleaning liquid, etc. Specifically, the liquid tank 220 is also provided with an atomizing nozzle 221, which is connected to the installation cavity 130 to spray mist into the installation cavity 130.

[0032] The embodiment of the present application does not limit the specific position of the atomizing device 200. The atomizing device 200 is disposed outside the installation cavity 130 or inside the installation cavity 130. For example, in the present embodiment, the atomizing device 200 is disposed inside the installation cavity 130, which can reduce the size of the vacuum cleaner 1. For the sake of convenience, the following description will take the atomizing device 200 disposed inside the installation cavity 130 as an example.

[0033] The atomizing assembly 210 may be an ultrasonic vibration atomizing assembly or a heating atomizing assembly. Preferably, the atomizing assembly 210 includes an ultrasonic atomizing sheet 211 disposed at the atomizing nozzle 221, and the ultrasonic atomizing sheet 211 can break up the liquid in the liquid tank 220 and form mist.

[0034] It should be noted that the ultrasonic atomizer 211 is an instrument that uses high-frequency electronic oscillation to break up liquid water molecules to produce naturally flowing mist. Its working principle is that through the high-frequency resonance of the atomizer, the liquid water molecule structure is broken up to form mist.

[0035] Furthermore, in one embodiment, a liquid injection port 222 is provided on the liquid tank 220, and the liquid injection port 222 is connected to the liquid tank 220. The atomizing device 200 further includes a cavity plug 230, and the cavity plug 230 is detachably mounted on the liquid injection port 222. When the liquid in the liquid tank 220 is exhausted, the user can remove the cavity plug 230 from the liquid injection port 222 to inject liquid into the liquid tank 220, and after the injection is completed, the cavity plug 230 can be plugged back into the liquid injection port 222. The embodiment of the present application does not limit the specific connection method between the cavity plug 230 and the liquid injection port 222, and can be specifically set according to actual conditions.

[0036] See also Figure 5 The embodiment of the present application does not limit the specific setting method of the liquid tank 220. For example, the liquid tank 220 can be detachably arranged relative to the shell 100, which can facilitate the user to replace the liquid tank 220. For example, in another embodiment, the liquid tank 220 can be integrally arranged with the shell 100. In this embodiment, the liquid filling port 222 can be opened on the side wall of the shell 100, which can improve the structural consistency of the entire vacuum cleaner 1 and prevent the vacuum cleaner 1 from colliding with the surrounding environment during use by the user, causing the liquid tank 220 to detach, thereby affecting the cleaning effect of the vacuum cleaner 1.

[0037] The embodiment of the present application does not limit the specific structure of the housing 100. For example, in one embodiment, the housing 100 can be set to a cylindrical structure, and the housing 100 has an air inlet 110 and an air outlet 120 that are connected to the installation cavity 130. The air inlet 110 can inhale air, and the air outlet 120 can exhaust air. It should be noted that the embodiment of the present application does not limit the specific structure and size of the air inlet 110 and the air outlet 120, and they can be set according to the actual needs of the user.

[0038] For further information, please also refer to Figure 4 and Figure 5 The housing 100 has a first partition 140, which partitions the installation cavity 130 into a first chamber 131 and a second chamber 132. As shown in the figure, in this embodiment, the first chamber 131 is connected to the second chamber 132 and is arranged above the second chamber 132. The air outlet 120 is connected to the first chamber 131, and the air inlet 110 is connected to the second chamber 132. The embodiment of the present application does not limit the specific structure of the first partition 140. For example, the first partition 140 is a partition with an opening in the middle, so that the first chamber 131 and the second chamber 132 can be connected.

[0039] A filter device 700 is disposed in the second chamber 132 to preliminarily filter dust gas entering the second chamber 132 from the air inlet 110 , and a filter element 600 is disposed in the first chamber 131 to secondary filter dust gas entering the first chamber 131 from the second chamber 132 .

[0040] For further information, please refer to Figure 4 The housing 100 further comprises a second partition 150, which is connected to the first partition 140 and divides the first chamber 131 into a third filter chamber 131a and a liquid tank 220. The air outlet 120 is in communication with the third filter chamber 131a.

[0041] Specifically, in this embodiment, the first partition 140 is horizontally disposed in the housing 100, and the second partition 150 is vertically connected to the first partition 140, so that the third filter cavity 131a and the liquid tank 220 are both connected to the second chamber 132. The embodiment of the present application also does not limit the specific structure of the second partition 150, for example, the second partition 150 is a partition.

[0042] In some embodiments, the shell 100 has a third partition 160, which is connected to the first partition 140. The third partition 160 divides the second chamber 132 into a second filter chamber 132b and a first filter chamber 132a. In this embodiment, the first filter chamber 132a is connected to the second filter chamber 132b, and the second filter chamber 132b is arranged inside the first filter chamber 132a. The atomizing nozzle 221 is connected to the first filter chamber 132a and the liquid tank 220, and the air inlet 110 is connected to the first filter chamber 132a.

[0043] The embodiment of the present application also does not limit the specific structure of the third partition 160. For example, the third partition 160 can be a filter to facilitate the connection between the first filter cavity 132a and the second filter cavity 132b.

[0044] It should be noted that the embodiments of the present application do not limit the specific structure of the filter. For example, in one embodiment, the filter may include a filter portion 161 and a dust collecting portion 162 , and the filter portion 161 is disposed between the first partition portion 140 and the dust collecting portion 162 .

[0045] The embodiment of the present application does not limit the specific structure of the dust collecting part 162, for example, it can be a cylindrical structure. Furthermore, in this embodiment, the diameter of the end of the dust collecting part 162 close to the filter part 161 can be larger than the end of the dust collecting part 162 away from the filter part 161, so that the cross-section of the dust collecting part 162 is a truncated cone structure.

[0046] Furthermore, the filter screen may be provided with a plurality of filter holes 163, and the plurality of filter holes 163 may be evenly arranged in the filter part 161, so that the filtering effect of the filter screen may be improved. In addition, in some embodiments, the filter part 161 may be detachably connected to the dust collecting part 162, so that the user may replace the filter part 161, and then may select a filter part 161 with a more suitable size of the filter hole 163 to adapt to different usage scenarios.

[0047] Specifically, in this embodiment, the air inlet 110 is arranged far away from the atomizing nozzle 221. As the air inlet 110 is far away from the atomizing nozzle 221, there is a sufficient distance between the air inlet 110 and the atomizing nozzle 221, so as to prevent the dust from combining with the mist and settling in the air inlet 110 as soon as the dust enters the second filter cavity 132b, causing the air inlet 110 to be blocked.

[0048] The embodiment of the present application does not limit the specific material of the shell 100. In the present embodiment, the shell 100 can be made of materials with high structural strength such as plastic and alloy. This can not only protect the driving device 400 and the atomizing device 200 arranged in the shell 100, but also improve the structural strength of the entire dust and gas separation device 10, thereby preventing the shell 100 from being damaged by collision with the environment during use.

[0049] Furthermore, in one embodiment, the shell 100 may be provided with an air intake pipe 300. The air intake pipe 300 may be provided on one side of the second chamber 132 and communicated with the second chamber 132. In this embodiment, the air inlet 110 may be provided on the air intake pipe 300. The air intake pipe 300 may facilitate the user to vacuum the external environment. For example, when the place to be vacuumed is relatively narrow, the air intake pipe 300 may be extended into the place to be vacuumed. The setting of the air intake pipe 300 is conducive to improving the applicability of the vacuum cleaner 1.

[0050] The embodiments of the present application do not limit the specific structure of the shell 100. For example, in one embodiment, the shell 100 includes: an outer shell 191 and an ash dump cover 192. The outer shell 191 and the ash dump cover 192 are connected to form an installation cavity 130.

[0051] The dust separated by the dust and gas separation device 10 falls into the ash dumping cover 192. When the ash dumping cover 192 is opened relative to the shell 191, the dust collected in the ash dumping cover can be dumped out and the ash dumping cover 192 can be cleaned.

[0052] It can be understood that the embodiment of the present application also does not limit the specific connection method between the shell 191 and the ash dump cover 192. For example, the shell 191 and the ash dump cover 192 are hinged or detachably connected, such as snap-on, adhesive, etc., which makes it convenient for users to inspect and repair components in the shell 100.

[0053] Please see here Figure 2 The driving device 400 can drive the dust gas to flow from the air inlet 110 toward the air outlet 120. In this embodiment, the driving device 400 can be arranged on the side of the collecting device close to the air outlet 120. The driving device 400 is a fan. The driving device 400 generates an airflow from the air inlet 110 to the air outlet 120 to achieve the effect of absorbing dust gas.

[0054] The power supply device 500 is electrically connected to the driving device 400 and is also electrically connected to the atomizing device 200 .

[0055] Furthermore, in this embodiment, the vacuum cleaner 1 may also include a controller 800, which may be disposed on one side of the power supply device 500, so that the wiring length between the controller 800 and the power supply device 500 can be reduced. The controller 800 is electrically connected to the power supply device 500 and to the atomizing device 200. The controller 800 is used to control the operation of the driving device 400 so that the driving device 400 generates an airflow from the air inlet 110 to the air outlet 120, and the controller 800 is also used to control the operation of the ultrasonic atomizing sheet 211, specifically, the controller 800 controls it to start or stop working, so as to break up the liquid in the liquid tank 220 and form mist.

[0056] The embodiment of the present application does not limit the specific form of the power supply device 500. For example, it can be a rechargeable battery or a disposable battery, etc., and the specific form can be selected according to actual conditions.

[0057] In this embodiment, the shell 100 also has a drive compartment 170 and a power supply compartment 180. The drive compartment 170 and the power supply compartment 180 can be arranged on the side away from the installation cavity 130. The drive compartment 170 is connected to the installation cavity 130, the drive device 400 is arranged in the drive compartment 170, and the power supply device 500 is arranged in the power supply compartment 180.

[0058] The working principle of the dust and gas vacuum cleaner 1 provided in the embodiment of the present application is as follows:

[0059] The driving device 400 can generate an airflow under the power supply of the power supply device 500, so that the air inlet 110 can absorb external dust and gas. When the dust and gas enter the installation cavity 130 from the air inlet 110, it combines with the mist generated by the atomization device 200. Specifically, the mist can be attached to the surface of the dust in the dust and gas to increase the weight of the dust, thereby promoting the sedimentation of the dust in the installation cavity 130. Clean air can be discharged from the air outlet 120 to achieve the effect of dust and gas separation. When the dust storage in the first filter cavity 132a is too much, the user can open the dust pouring cover 192 and pour out the dust in the first filter cavity 132a.

[0060] The dust-gas separation device 10 provided in the embodiment of the present application forms an installation cavity 130 inside the housing 100, and provides an atomizing device 200 connected to the installation cavity 130. The atomizing device 200 can spray mist into the installation cavity 130, so that the dust in the installation cavity 130 can adhere to the mist, thereby increasing the weight of the dust, which can facilitate dust sedimentation to improve the separation effect of air and dust in the dust. When the dust-gas separation device 10 provided in the embodiment of the present application is applied to the vacuum cleaner 1, the dust-gas separation effect of the vacuum cleaner 1 can be improved. When the dust-gas separation device 10 provided in the embodiment of the present application is applied to the vacuum cleaner 1, the dust-gas separation effect of the vacuum cleaner 1 can be improved.
