Description

Technical Field

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

[0002] Currently, with the improvement of living quality, people's demand for cleaning tools is becoming more and more extensive. Automated cleaning equipment is widely used because it can liberate physical labor. As a cleaning device, a mite remover is used to remove dust and mites on the surfaces of mattresses, leather materials, etc.

[0003] In related technologies, a mite remover usually includes a housing, a blower, and a dust collection device. Starting the blower can generate negative pressure suction. The airflow generated by the suction sucks dust and mites into the dust collection device through the air inlet of the housing, and then the clean airflow filtered by the dust collection device is discharged through the air outlet of the housing.

[0004] However, currently, the air volume loss between the blower and the air outlet of the mite remover is small, but the noise is large. Utility Model Content

[0005] This application provides a mite removal device to solve the problem that the air volume loss between the blower and the air outlet of the current mite remover is small, resulting in a large noise.

[0006] To achieve the above object, the technical solution of this application is as follows:

[0007] This application provides a mite removal device, including: a housing assembly that defines an air flow channel and an air inlet and an air outlet that communicate with the air flow channel; a dust collection device disposed in the air flow channel and located downstream of the air inlet along the air flow direction; a blower disposed in the air flow channel and located downstream of the dust collection device along the air flow direction. The blower drives the air flow to flow from the air inlet through the dust collection device and the blower to the air outlet in sequence. A wind blocking structure is provided in the part of the air flow channel located downstream of the blower, and the wind blocking structure is configured to extend the air flow circulation path between the blower and the air outlet.

[0008] According to the mite removal device of this application, by setting the housing assembly to define the air flow channel, as well as the air inlet and the air outlet that communicate with the air flow channel, both the dust collection device and the blower are disposed in the air flow channel. Starting the blower, the blower drives the air flow to enter the air flow channel from the air inlet and flow to the air outlet after being filtered by the dust collection device. When the air flow flows to the air outlet, it flows through the wind blocking structure in the part of the air flow channel located downstream of the blower. By setting the wind blocking structure, the air flow circulation path is extended, the air volume loss is increased, and the noise of the mite removal device is effectively reduced.

[0009] In some embodiments, there is at least one windscreen structure, which is connected to the channel wall of the air flow channel. The windscreen structure has a first surface close to the fan and a second surface far from the fan on the air flow path. The air flow flows through the first surface and the second surface in sequence, and the flow direction of the air flow along the first surface is opposite to that along the second surface.

[0010] In this way, by setting the first surface and the second surface, the air flow needs to flow along the first surface and the second surface in sequence, effectively extending the air flow path, increasing the air volume loss, and reducing the noise.

[0011] In some embodiments, the fan includes a housing with an air outlet, and the windscreen structure is arranged opposite to at least one of the air outlet and the air discharge port.

[0012] In this way, the air flow driven by the fan can be affected by the windscreen structure, changing the flow direction and avoiding the air flow directly impacting the air discharge port to generate noise and vibration.

[0013] In some embodiments, both the air outlet and the windscreen structure extend along the circumferential direction of the housing. The windscreen structure is opposite and spaced apart from the air outlet along the opening direction of the air outlet. In the circumferential direction of the housing, both ends of the windscreen structure extend beyond both ends of the air outlet.

[0014] In this way, when the air flow is discharged from the air outlet, the air flow needs to flow along the windscreen structure and then be discharged from the air discharge port, extending the air flow path. Moreover, by both ends of the windscreen structure extending beyond both ends of the air outlet, it can be ensured that when the air flow is discharged from the positions at both ends of the air outlet, it can also flow towards the windscreen structure, thereby improving the guiding effect of the windscreen structure on the air flow.

[0015] In some embodiments, a first air duct section is defined between the first surface of the windscreen structure and the housing, and a second air duct section is defined between the second surface of the windscreen structure and the housing assembly. Both the first air duct section and the second air duct section form part of the air flow channel. At least one end of the windscreen structure along the circumferential direction of the housing defines a communication port connecting the first air duct section and the second air duct section, and the communication port is circumferentially staggered from the air outlet.

[0016] In this way, after the air flow passes through the air outlet, it first flows through the first air duct section and then enters the second air duct section through the communication port, so that when the air flow passes between the air outlet and the air discharge port, more swirls can be generated, reducing the noise when the air flow passes through the air discharge port.

[0017] In some embodiments, the width of the communication port along the circumferential direction of the outer shell is not less than 2 cm.

[0018] In this way, it helps to optimize the flow of the air current and improve the flow efficiency of the air current.

[0019] In some embodiments, the air outlet faces the bottom wall of the housing assembly, both ends of the wind blocking structure along the circumferential direction of the outer shell define a communication port with the housing assembly, there are two exhaust ports, and the two exhaust ports are respectively located on both sides of the fan. The fan is adapted to drive the air current to flow to the corresponding exhaust port through the two communication ports respectively.

[0020] In this way, the smooth flow of the air current is ensured.

[0021] In some embodiments, an air passing port is provided at a position of the wind blocking structure opposite to the air outlet. The air passing port communicates the first air duct section and the second air duct section along the opening direction of the air outlet. The width of the air passing port is smaller than the width of the air outlet, and the two exhaust ports are respectively located on both sides of the air passing port.

[0022] In this way, after a part of the air current is discharged from the air outlet, it directly enters the second air duct section through the air passing port and then flows towards the exhaust port, while another part of the air current flows towards both sides of the air outlet from the first air duct section to flow towards the exhaust port respectively, taking into account both the noise reduction effect and the air current flow efficiency.

[0023] In some embodiments, the housing assembly includes an upper shell and a lower shell. The upper shell and the lower shell are connected to each other and jointly define an installation space. The installation space constitutes a part of the air current channel. At least the structure of the fan is arranged in the installation space. The wind blocking structure is in the installation space and is connected to the lower shell.

[0024] In this way, through the mutual connection of the upper shell and the lower shell, an installation space for accommodating the fan and the wind blocking structure is formed, while ensuring the integrity and sealing performance of the air current channel.

[0025] In some embodiments, the wind blocking structure is integrally formed with the lower shell.

[0026] In this way, integral forming can enhance the connection strength between the wind blocking structure and the lower shell, and improve the stability and durability of the wind blocking structure during use. Description of the Drawings

[0050] In order to make the above - mentioned objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0051] As a cleaning device, a mite remover is used to remove dust and mites on the surfaces of beddings, leather materials, etc. In related technologies, a mite remover usually includes a housing, a fan, and a dust collection device. Starting the fan can generate negative pressure suction, and the airflow generated by the suction sucks dust and mites into the dust collection device through the air inlet of the housing, and then the clean airflow filtered by the dust collection device is discharged through the air outlet of the housing. However, currently, the distance between the fan and the air outlet of the mite remover is relatively short, so that the airflow circulation path is short and the air volume loss is small, resulting in a relatively large noise.

[0052] In view of this, the present application provides a mite removal device. By setting a housing assembly to define an airflow channel, as well as an air inlet and an air outlet communicating with the airflow channel, the dust collection device and the fan are both arranged in the airflow channel. Starting the fan, the fan drives the airflow to enter the airflow channel from the air inlet and flow to the air outlet after being filtered by the dust collection device. When the airflow flows to the air outlet, it flows through a wind - blocking structure on the downstream side of the fan in the airflow channel. By setting the wind - blocking structure, the airflow circulation path is extended, the air volume loss is increased, and the noise and vibration of the mite removal device are effectively reduced.

[0053] The following will be a detailed description of the present application in conjunction with the drawings and specific embodiments.

[0054] See Figures 1 to 5 , the present application provides a mite removal device 10, which can be a handheld mite remover or other devices. The mite removal device 10 can perform mite removal and cleaning operations on mattresses, sofas, quilts, towels, and other cleaning objects prone to mite growth. The mite removal device 10 can include: a housing assembly 100, a dust collection device 200, and a fan 300.

[0055] Among them, the housing assembly 100 defines an air flow channel, an air inlet, and an air outlet 110 communicating with the air flow channel. The dust collection device 200 is disposed in the air flow channel and is located on the downstream side of the air inlet along the air flow direction. The fan 300 is disposed in the air flow channel and is located on the downstream side of the dust collection device 200 along the air flow direction. When the mite removal device is working, the fan 300 generates suction force to drive the air flow to carry impurities such as mites and dust in the object to be cleaned into the air flow channel from the air inlet, and then flows through the dust collection device 200 and the fan 300 in sequence to the air outlet 110. A wind blocking structure 400 (see Figure 5 ) is provided in a part of the air flow channel located on the downstream side of the fan 300, and the wind blocking structure 400 is configured to extend the air flow circulation path between the fan 300 and the air outlet 110.

[0056] In the present application, by providing the housing assembly 100 to construct an air flow channel (not shown in the figure), it is ensured that the air flow can smoothly and orderly enter the mite removal device 10 from the air inlet (not shown in the figure). After the air flow passes through the dust collection device 200, it is finally discharged to the outside of the mite removal device 10 from the air outlet 110. In this way, the purpose of mite removal by using the mite removal device 10 can be achieved, thereby achieving a better cleaning effect.

[0057] Further, the dust collection device 200 can be a dust cup or other containers suitable for storing and filtering impurities in the air. The impurities can be mites, hairs, dust, etc. The dust collection device 200 is located on the downstream side of the air inlet along the air flow direction. In this way, the air flow entering the mite removal device 10 can pass through the dust collection device 200 for dust removal treatment, effectively capturing and collecting fine particles such as mites and dust in the air. The efficient operation of the dust collection device 200 significantly improves the ability of the mite removal device 10 to remove minute pollutants and ensures the cleanliness of the air.

[0058] In some embodiments, the fan 300, as the core component for driving the air flow circulation, is disposed behind the dust collection device 200. In this way, it is ensured that the air inhaled by the fan 300 is preliminarily purified air, reducing the pollution inside the fan 300, and at the same time, the negative pressure suction force generated by the fan 300 can be fully utilized to push the air flow to continue flowing, ensuring that the air in the entire air flow channel is always in an active state and improving the mite removal efficiency of the mite removal device 10.

[0059] It should be noted that a wind blocking structure 400 is provided in the air flow channel on the downstream side of the fan 300. Through the wind blocking structure 400, the air flow circulation path from the fan 300 to the air outlet 110 is extended. Thus, the air volume loss can be increased to effectively reduce noise and vibration and improve the use experience of the mite removal device 10.

[0060] See Figure 2 and Figure 5, in the embodiments of the present application, there is at least one windshield structure 400, and the windshield structure 400 is connected to the channel wall 120 of the air flow channel to utilize the channel wall 120 of the air flow channel to provide support for the windshield structure 400. The windshield structure 400 has a first surface 410 close to the fan 300 and a second surface 420 far from the fan 300 on the air flow path. In other words, when the air flows in the air flow channel, it will flow through the first surface 410 and the second surface 420 in sequence, and moreover, the flow direction of the air when flowing along the first surface 410 is opposite to the flow direction when flowing along the second surface 420. In this way, the length of the air flow path can be effectively increased.

[0061] Specifically, the windshield structure 400 is arranged to be connected to the channel wall of the air flow channel. In this way, the structural stability of the windshield structure 400 is enhanced, ensuring that the windshield structure 400 can effectively guide and control the flow direction of the air flow. By adjusting the position and shape of the windshield structure 400, the distribution and speed of the air flow can be further optimized, improving the mite removal efficiency.

[0062] It can be understood that the windshield structure 400 can be arranged as one, in this way, the air flow path between the fan 300 and the air outlet 110 is extended. The windshield structure 400 can also be arranged as multiple ones, and multiple ones can be more than two (such as two or three, etc.), and moreover, multiple windshield structures 400 can be arranged staggered one by one along the air flow path. In this way, the air flow path can be further extended, ensuring that there is enough air flow path between the fan 300 and the air outlet of the housing assembly 100 to increase the loss of the air flow on the downstream side of the fan 300, thereby effectively achieving the noise reduction effect.

[0063] It should be noted that the windshield structure 400 has a first surface 410 and a second surface 420, and the first surface 410 and the second surface 420 are respectively close to and far from the fan 300 on the air flow path. During the operation of the mite removal device 10, when the air is discharged from the fan 300, its flow direction is guided by the windshield structure 400 and flows along the first surface 410. Then, the air flows from the first surface 410 to the second surface 420 to continue flowing along the second surface 420. At this time, the flow direction of the air changes and is opposite to the flow direction when flowing along the first surface 410. Thus, by the air flowing along the first surface 410 and the second surface 420 in sequence, the air flow path between the fan 300 and the air outlet 110 is effectively extended, the air volume loss is increased, and the noise and vibration are effectively reduced. At the same time, the user experience is improved, and the service life of the mite removal device 10 is extended.

[0064] See Figure 2 and Figure 5, in the embodiments of the present application, the fan 300 may include a housing 310 and structures such as a motor and an impeller disposed inside the housing 310. The housing 310 may be generally cylindrical or volute-shaped, and of course, it may also be of other structures. The motor can drive the impeller to rotate to generate a suction force for driving the air flow to circulate. The housing 310 is provided with an air outlet 311, and the wind deflector structure 400 is arranged opposite to at least one of the air outlet 311 and the air discharge port 110. Of course, the housing 310 may be provided with an air inlet, and the air inlet can be communicated with the outlet of the dust collection device 200.

[0065] Among them, by arranging the wind deflector structure 400 opposite to the air outlet 311 or the air discharge port 110, the direct guidance and regulation of the air outlet 311 of the fan 300 are realized, ensuring that the air flow discharged from the fan 300 can be immediately affected by the wind deflector structure 400, thereby changing its flow direction and speed. Thereby, the guiding efficiency of the air flow is improved, the noise and vibration that may be generated by the air flow directly impacting the air discharge port 110 are avoided, and the overall performance of the mite removal device 10 is enhanced.

[0066] In addition, through the guidance of the wind deflector structure 400 on the air flow discharged from the air outlet 311 of the fan 300, the mixing and disturbance effects on the air flow are also enhanced. Under the action of the wind deflector structure 400, the air flow is forced to change direction, which helps to more evenly disperse the fine particles in the air flow throughout the air flow channel, improving the mite removal and purification effects.

[0067] See Figure 2 and Figure 5 , in the embodiments of the present application, both the air outlet 311 and the wind deflector structure 400 extend along the circumferential direction of the housing 310. The wind deflector structure 400 is opposite and spaced from the air outlet 311 along the opening direction of the air outlet 311. In the circumferential direction of the housing 310, both ends of the wind deflector structure 400 extend beyond both ends of the air outlet 311. For example, the center lines of the air outlet 311 and the wind deflector structure 400 are collinear, and the arc corresponding to both circumferential ends of the wind deflector structure 400 is greater than the arc corresponding to both circumferential ends of the air outlet 311 along the housing 310. In this way, it can be ensured that when the air flow is discharged from the positions at both ends of the air outlet 311, it can also flow towards the wind deflector structure 400, rather than flowing from both sides of the wind deflector structure 400 to the air discharge port 110 without passing through the first surface 410 of the wind deflector structure 400, thereby improving the guiding effect of the wind deflector structure 400 on the air flow and avoiding the reduction of the noise reduction effect.

[0068] Furthermore, the wind deflector structure 400 extends beyond the air outlet 311 at both ends in the circumferential direction of the outer shell 310, enabling the wind deflector structure 400 to guide the airflow at the air outlet 311 and form a certain barrier effect on both sides of the air outlet 311 to limit the direct diffusion range of the airflow. After the airflow flows out through the air outlet 311, it flows along the wind deflector structure 400 and then is discharged through the air exhaust port 110. Thus, the airflow circulation path is effectively extended, and the noise and vibration are reduced.

[0069] See Figure 2 and Figure 5 , in the embodiment of the present application, a first air duct section 430 is defined between the first surface 410 of the wind deflector structure 400 and the outer shell 310, and a second air duct section 440 is defined between the second surface 420 of the wind deflector structure 400 and the housing assembly 100. Both the first air duct section 430 and the second air duct section 440 form part of the airflow passage. At least one end of the wind deflector structure 400 along the circumferential direction of the outer shell 310 and the housing assembly 100 define a communication port 450 that connects the first air duct section 430 and the second air duct section 440. The communication port 450 is circumferentially offset from the air outlet 311 along the outer shell 310.

[0070] Among them, the settings of the first air duct section 430 and the second air duct section 440 enable the airflow to change direction and turn the path when passing through the wind deflector structure 400. In this way, the airflow circulation path is extended, which helps to better improve the noise reduction effect.

[0071] It should be noted that since the communication port 450 is circumferentially offset from the air outlet 311 along the outer shell 310, after the airflow passes through the air outlet 311, it does not directly enter the second air duct section 440, but first flows and diffuses for a certain distance and then enters the second air duct section 440 through the communication port 450. In this way, when the airflow passes between the air outlet 311 and the air exhaust port 110, more swirls can be generated, reducing the noise when the airflow passes through the air exhaust port 110 and improving the user experience.

[0072] In the embodiment of the present application, the width of the communication port 450 along the circumferential direction of the outer shell 310 is not less than 2 cm, for example, it can be 2 cm, 3 cm, 4 cm, etc.

[0073] It can be understood that setting the width of the communication port 450 to be not less than 2 cm ensures the smooth flow of the airflow. The wider communication port 450 reduces the resistance when the airflow changes the flow direction, enabling the airflow to flow more smoothly from the first air duct section 430 to the second air duct section 440, and avoiding the air congestion and turbulence phenomena caused by the narrow communication port 450. In this way, the airflow circulation efficiency is improved, making the operation of the entire airflow passage more efficient.

[0074] Moreover, the wider communication opening 450 helps to optimize the distribution of the air flow. When the air flow passes through the wider communication opening 450, its diffusion range is wider, and it can be more evenly distributed into the second air duct section 440, which helps to improve the overall performance and stability of the mite removal device 10.

[0075] See Figure 2 and Figure 5 , in the embodiment of the present application, the air outlet 311 faces the bottom wall of the housing assembly 100. Both ends of the wind shield structure 400 along the circumferential direction of the outer shell 310 define a communication opening 450 with the housing assembly 100. There are two air exhaust ports 110, and the two air exhaust ports 110 are respectively located on both sides of the fan 300. The fan 300 is adapted to drive the air flow to flow to the corresponding air exhaust ports 110 through the two communication openings 450 respectively.

[0076] It can be understood that by arranging the air outlet 311 of the fan 300 to face the bottom wall of the housing assembly 100, the air flow discharged from the air outlet 311 can first flow downward and then flow toward the air exhaust ports 110 on both sides of the housing assembly 100, realizing the directional discharge of the air flow, effectively avoiding the air flow directly blowing to the user or surrounding objects after being discharged from the air exhaust ports 110, reducing unnecessary interference and discomfort, and improving the user experience. In addition, the air flow path is optimized, so that the air flow can be discharged more smoothly, enhancing the heat dissipation efficiency and air circulation effect of the mite removal device 10.

[0077] Furthermore, the communication opening 450 defined between the two circumferential ends of the wind shield structure 400 and the housing assembly 100 ensures the smooth flow of the air flow. When the fan 300 is operating, it can more efficiently drive the air flow to pass through these two communication openings 450 respectively, and then flow to the corresponding air exhaust ports 110, realizing the diversion and uniform distribution of the air flow, avoiding the air flow congestion that may be caused by a single channel, and further improving the efficiency of air circulation.

[0078] See Figure 5 , in the embodiment of the present application, an air passing opening 460 is provided at a position of the wind shield structure 400 opposite to the air outlet 311. The air passing opening 460 communicates the first air duct section 430 and the second air duct section 440 along the opening direction of the air outlet 311. The width of the air passing opening 460 is smaller than the width of the air outlet 311. The two air exhaust ports 110 are respectively located on both sides of the air passing opening 460.

[0079] In specific implementation, the air passing opening 460 is arranged at a position of the wind shield structure 400 opposite to the air outlet 311, communicating the first air duct section 430 and the second air duct section 440, so that the air flow can smoothly transition from the first air duct section 430 to the second air duct section 440. Thus, through the continuous air flow path, it helps to improve the stability of the air flow.

[0080] It should be noted that the width of the air passing opening 460 is smaller than the width of the air outlet 311, so that a part of the structure of the wind blocking structure 400 faces the air outlet 311. In this way, after a part of the air flow is discharged from the air outlet 311, it directly enters the second air duct section 440 through the air passing opening 460, and then flows toward the two sides of the circumferential direction of the air passing opening 460 to the two air discharge openings 110 respectively. Another part of the air flow (that is, the air flow discharged from both ends of the air passing opening 460) is blocked and guided by the wind blocking structure 400 and flows from the first air duct section 430 to both sides of the air outlet 311 to flow to the two air discharge openings 110 respectively. In this way, it helps to further guide and restrict the air flow, and at the same time can increase the air flow efficiency, and then take into account the noise reduction effect and the air flow efficiency, which is beneficial to improving the user experience.

[0081] See Figure 3 , in the embodiment of the present application, the housing assembly 100 includes an upper housing 130 and a lower housing 140, and the upper housing 130 and the lower housing 140 are connected to each other. For example, the upper housing 130 and the lower housing 140 can be bolted, snap-connected, etc. An accommodation space can be jointly defined between the upper housing 130 and the lower housing 140, and the accommodation space forms a part of the air flow channel. At least the structure of the fan 300 is arranged in the accommodation space, and the wind blocking structure 400 is in the accommodation space and is connected to the lower housing 140.

[0082] It can be understood that through the mutual connection of the upper housing 130 and the lower housing 140, a firm and sealed accommodation space is formed. In this way, a stable installation environment is provided for the fan 300 and the wind blocking structure 400, and at the same time, the integrity and sealing of the air flow channel are ensured.

[0083] In specific implementation, at least part of the structure of the fan 300 is arranged in the accommodation space, so that the fan 300 can operate in a relatively closed environment. In this way, it can ensure that the air flow flows along a relatively fixed flow path and ensure the flow efficiency.

[0084] Furthermore, the wind blocking structure 400 is installed in the accommodation space and is tightly connected to the lower housing 140, so that the wind blocking structure 400 can play a more stable role in precisely guiding and regulating the air flow. By setting the wind blocking structure 400, the flow direction and speed of the air flow are optimized. At the same time, the connection method between the wind blocking structure 400 and the lower housing 140 enhances the structural strength of the entire housing assembly 100.

[0085] In the embodiment of the present application, the wind blocking structure 400 is integrally formed with the lower housing.

[0086] It can be understood that by adopting an integral molding method, the connection strength between the windshield structure 400 and the lower housing 140 can be significantly enhanced. Compared with split assembly, integral molding can ensure a tight connection between the windshield structure 400 and the lower housing 140, improve the stability and durability of the windshield structure 400 during use, and extend the service life of the mite removal device 10.

[0087] In addition, the integral molding design simplifies the production process. During production, the windshield structure 400 and the lower housing 140 can be processed and formed simultaneously without additional assembly steps. Thus, the production cost is reduced and the production efficiency is improved.
