Abstract
Description
Technical Field
[0001] This application belongs to the field of cleaning technology, and particularly relates to a cleaning device. Background Art
[0002] With the development of social economy, home cleaning has gradually entered the era of intelligence and mechanization. The emergence of cleaning devices has further liberated people from the heavy workload of home cleaning and alleviated the fatigue of people during home cleaning. The laser module of existing cleaning devices is sensitive to temperature and it is difficult to ensure the normal use of the laser module at higher temperatures. Therefore, it is necessary to dissipate heat from the laser module inside the cleaning device to prevent the temperature of the laser module from exceeding the required temperature.
[0003] In the prior art, generally, larger or more fans and radiators are used to cool the entire main cabin of the cleaning device to achieve heat dissipation of the laser module. However, since other components in the main cabin do not require cooling during normal use to meet the normal working requirements, the method of cooling the entire main cabin increases unnecessary costs to a certain extent, resulting in a higher heat dissipation cost.
[0004] Therefore, the existing method of dissipating heat from the laser module has the defect of high heat dissipation cost. Summary of the Utility Model
[0005] The purpose of the embodiments of this application is to provide a cleaning device that can solve the problem of high heat dissipation cost of the laser module in related cleaning devices.
[0006] The embodiments of this application provide a cleaning device, including:
[0007] A device main body provided with a main cabin;
[0008] A laser module disposed in the main cabin;
[0009] A radiator disposed in the main cabin and connected to the cabin wall of the main cabin, and the laser module is disposed on the radiator;
[0010] A blowing component disposed on the device main body, at least part of the blowing component extends into the main cabin, and the air outlet of the blowing component faces the radiator, and the blowing component is used to blow air to the radiator.
[0011] In the embodiment of the present application, the laser module is disposed on the radiator, and the air outlet of the air blowing component faces the radiator and is used to blow air to the radiator. In this way, the radiator and the air blowing component can independently dissipate heat from the laser module. Compared with the way of using a fan to dissipate heat from the entire main body of the cleaning device, the temperature rise of the laser module can be effectively reduced, and the heat dissipation effect can be improved. Moreover, since the radiator and the air blowing component only dissipate heat from the laser module, a small air blowing component and a radiator can be selected to achieve heat dissipation for the laser module, which is beneficial to reducing the heat dissipation cost.

[0038] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0039] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.
[0040] Next, the cleaning device provided in the embodiments of the present application will be described in detail with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0041] Reference Figures 1 - 18 , a cleaning device provided in an embodiment of the present application may include a device main body 100, a laser module 300, a radiator 400, and a blowing component 500.
[0042] Among them, the device main body 100 may be provided with a main machine compartment 140. Both the laser module 300 and the radiator 400 may be disposed in the main machine compartment 140, and the radiator 400 may be connected to the wall of the main machine compartment 140. The laser module 300 may be disposed on the radiator 400. In this way, the radiator 400 can be directly connected to the laser module 300 and can directly dissipate the heat of the laser module 300, which is beneficial to reducing the temperature rise of the laser module 300.
[0043] In addition, the blowing component 500 may be disposed on the device main body 100. At least a part of the blowing component 500 may extend into the main machine compartment 140, and the air outlet 530 of the blowing component 500 may face the radiator 400. The blowing component 500 may be used to blow air to the radiator 400. In this way, it is beneficial to quickly cool the radiator 400, thereby improving the heat dissipation effect on the laser module 300.
[0044] With such a setting, the radiator 400 and the blowing component 500 can dissipate heat from the laser module 300 independently. Compared with the way of dissipating heat from the entire main cabin 140 of the cleaning device, it can effectively reduce the temperature rise of the laser module 300 and improve the heat dissipation effect. Moreover, since the radiator 400 and the blowing component 500 only dissipate heat from the laser module 300, a small blowing component 500 and a radiator 400 can be selected to achieve heat dissipation for the laser module 300, which is conducive to reducing the heat dissipation cost.
[0045] In an alternative embodiment of the present application, the blowing component 500 may include a fan 510 and a blowing duct 520. The fan 510 may be disposed on the device main body 100, the blowing duct 520 may be located in the main cabin 140, and the inlet of the blowing duct 520 may be connected to the air outlet end of the fan 510. Here, the outlet of the blowing duct 520 may be the air outlet 530 of the blowing component 500. With such a setting, the blowing duct 520 can guide the air blown out by the fan 510 to the radiator 400, making it easier for the cold air to act on the radiator 400, and further improving the heat dissipation effect of the laser module 300.
[0046] In other embodiments, the blowing component 500 may also only include the fan 510 and not include the blowing duct 520, and the air outlet end of the fan 510 may face the radiator 400.
[0047] Optionally, the outlet of the blowing duct 520 may be arranged close to the radiator 400. In this way, it is more convenient for the cold air to act on the radiator 400, and the heat dissipation effect can be improved. Of course, the outlet of the blowing duct 520 may also not be arranged close to the radiator 400.
[0048] In an alternative embodiment, the blowing duct 520 may include a first duct 521 and a second duct 522. The inlet of the second duct 522 may communicate with the outlet of the first duct 521, and the outlet of the second duct 522 may face the radiator 400, that is, the outlet of the second duct 522 is the air outlet 530 of the blowing component 500. And, along the direction from the inlet of the first duct 521 to the outlet of the first duct 521, the cross-sectional area of the lumen of the first duct 521 gradually decreases, that is, the lumen of the first duct 521 gradually narrows, and the cross-sectional area of the lumen of the second duct 522 is equal to the minimum cross-sectional area of the lumen of the first duct 521. In this way, when the air flow passes through the first duct 521, due to the gradual narrowing of the lumen of the first duct 521, the lumen of the first duct 521 restricts the diffusion of the air flow, resulting in an increase in the air speed, and further increasing the air speed of the air flow acting on the radiator 400, thereby further improving the heat dissipation effect of the radiator 400; and the second duct 522 can direct the air to the radiator 400 to ensure that the cold air can accurately act on the radiator 400.
[0049] It should be noted that the cross-section of the lumen of the first duct 521 can be perpendicular to the longitudinal direction of the first duct 521, and the cross-section of the lumen of the second duct 522 can be perpendicular to the longitudinal direction of the second duct 522.
[0050] In other embodiments, along the direction from the inlet of the first duct 521 to the outlet of the first duct 521, the cross-sectional area of the lumen of the first duct 521 can also remain unchanged.
[0051] Optionally, the second duct 522 can include an inclined section 5221 and a horizontal section 5222. The inlet of the inclined section 5221 can be in communication with the outlet of the first duct 521, the inlet of the horizontal section 5222 can be in communication with the outlet of the inclined section 5221, and the outlet of the horizontal section 5222 can face the radiator 400. Here, the outlet of the horizontal section 5222 can be the air outlet 530 of the blowing assembly 500. Moreover, the longitudinal direction of the inclined section 5221 can intersect with the longitudinal direction of the horizontal section 5222. In this way, it is convenient for the blowing duct 520 to avoid other components in the main engine compartment 140, and thus it is convenient to install the blowing assembly 500.
[0052] Further optionally, the wall of the lumen of the first duct 521 can be a smooth curved surface. In this way, the smooth curved surface can make the air flow through more smoothly, reduce the separation of the air flow and the formation of eddy currents, so as to reduce the loss of air volume. Furthermore, more cold air can act on the radiator 400, thereby improving the heat dissipation effect of the radiator 400. Here, the wall of the lumen of the first duct 521 can be a conical structure.
[0053] Of course, the wall of the lumen of the first duct 521 can also not be a smooth curved surface. Specifically, the wall of the lumen of the first duct 521 can include a plurality of planes.
[0054] In an alternative embodiment, the device main body 100 can be provided with a mounting hole 1131. The mounting hole 1131 can be in communication with the main engine compartment 140, and at least a part of the fan 510 can be located in the mounting hole 1131. In this way, the fan 510 can be mounted on the device main body 100, and it is convenient for the fan 510 to introduce external air into the main engine compartment 140.
[0055] To facilitate the installation of the fan 510, at least two limit posts 1132 may be provided on the device main body 100. Each limit post 1132 may be located within the main machine compartment 140. The limit posts 1132 may be circumferentially spaced apart along the circumference of the mounting hole 1131, and the limit posts 1132 may be in contact with the fan 510. In this way, the limit posts 1132 can support and position the fan 510. When installing the fan 510, the limit posts 1132 can play a role in pre-fixing the fan 510, facilitating the operator to connect the fan 510 to the device main body 100, and thus improving the installation convenience. Optionally, the housing of the fan 510 may also be connected to the device main body 100 through fixing parts such as screws to improve the fixing stability of the fan 510.
[0056] Of course, in other embodiments, the limit posts 1132 may not be provided on the device main body 100, and the fan 510 may be directly connected to the device main body 100 through screws.
[0057] In this embodiment, four limit posts 1132 may be provided on the device main body 100, and the four limit posts 1132 may be evenly distributed along the circumference of the mounting hole 1131. In this way, the pre-fixing effect on the fan 510 can be improved.
[0058] Optionally, the surfaces of the limit posts 1132 facing the fan 510 may all be arc-shaped surfaces, and the center of the arc-shaped surface is located on the axis of the mounting hole 1131. In this way, both the positioning effect on the fan 510 can be improved, and the stress and wear between the limit posts 1132 and the fan 510 can be reduced, which is beneficial to extending the service life of the fan 510. Of course, the surfaces of the limit posts 1132 facing the fan 510 may also be flat surfaces.
[0059] In some embodiments, the fan 510 and the blowing duct 520 may be fixedly connected by screws. Specifically, the blowing duct 520 may be connected to the housing of the fan 510 through screws. Optionally, to reduce the number of screws, the housing of the fan 510, the blowing duct 520, and the device main body 100 may be connected by the same screw.
[0060] In an alternative embodiment of the present application, the heat sink 400 may include a first heat dissipation part 410 and a second heat dissipation part 420. The first heat dissipation part 410 may include a first heat dissipation substrate 411 and a plurality of first heat dissipation fins 412. Each of the first heat dissipation fins 412 may be disposed on the first heat dissipation substrate 411. The surface of the first heat dissipation substrate 411 facing away from the first heat dissipation fins 412 may be adhesively connected to the wall of the main machine compartment 140. The second heat dissipation part 420 may include a second heat dissipation substrate 421 and a plurality of second heat dissipation fins 422. The second heat dissipation substrate 421 may be connected to the first heat dissipation substrate 411. Each of the second heat dissipation fins 422 may be disposed on the second heat dissipation substrate 421. And the laser module 300 may be disposed on the surface of the second heat dissipation substrate 421 facing away from the second heat dissipation fins 422. In this way, on the one hand, heat dissipation fins are provided on both the first heat dissipation substrate 411 and the second heat dissipation substrate 421, which can improve the heat dissipation effect of the heat sink 400. On the other hand, since the first heat dissipation substrate 411 is adhesively connected to the wall of the main machine compartment 140, it can not only fix the laser module 300, but also conduct the heat of the laser module 300 to the wall of the main machine compartment 140 through the first heat dissipation substrate 411, thereby improving the heat dissipation effect of the laser module 300.
[0061] In this embodiment, the first heat dissipation part 410 may be connected to the wall of the main machine compartment 140 by at least two screws. Specifically, the first heat dissipation part 410 may be connected to the front cover plate 112 described below by at least two screws. Optionally, the first heat dissipation part 410 may be provided with two fixing holes 413. The two fixing holes 413 may be respectively disposed near opposite ends of the first heat dissipation part 410. The screws may pass through the fixing holes 413 to be connected to the front cover plate 112 to connect the first heat dissipation part 410 to the front cover plate 112. And, in order to avoid interference between the first heat dissipation part 410 and other fixing parts or components on the front cover plate 112, the first heat dissipation part 410 may be provided with a plurality of avoidance holes 414. It should be noted that the shapes or sizes of the avoidance holes 414 may be the same or different, and no specific limitation is imposed here.
[0062] In other embodiments, the heat sink 400 may only include the first heat dissipation part 410, and the laser module 300 may be disposed on the first heat dissipation part 410.
[0063] Optionally, in the direction from the second heat dissipation part 420 to the first heat dissipation part 410, the length of the orthographic projection of the first heat dissipation part 410 can be greater than the length of the orthographic projection of the second heat dissipation part 420. In this way, compared with the way that the length of the orthographic projection of the first heat dissipation part 410 is less than or equal to the length of the orthographic projection of the second heat dissipation part 420 in the direction from the second heat dissipation part 420 to the first heat dissipation part 410, the fitting area between the radiator 400 and the main engine compartment 140 can be increased, thereby improving the fixing stability of the radiator 400 and also improving the heat dissipation effect of the radiator 400. Of course, in the direction from the second heat dissipation part 420 to the first heat dissipation part 410, the length of the orthographic projection of the first heat dissipation part 410 can also be less than or equal to the length of the orthographic projection of the second heat dissipation part 420.
[0064] Further optionally, the air outlet 530 of the blowing component 500 can cover one end of the second heat dissipation part 420 close to the air outlet 530. In this way, it can ensure that the air flow covers the entire second heat dissipation part 420 to improve the utilization rate of air cooling and thus improve the heat dissipation effect. Of course, the air outlet 530 of the blowing component 500 may not cover one end of the second heat dissipation part 420 close to the air outlet 530. Specifically, the air outlet 530 of the blowing component 500 can only cover a part of the second heat dissipation part 420. For example, the air outlet 530 of the blowing component 500 can only cover one end of the second heat dissipation substrate 421 close to the air outlet 530.
[0065] Here, the cross-sectional area of the air outlet 530 of the blowing component 500 can be greater than or equal to the cross-sectional area of the second heat dissipation part 420 so that the air outlet 530 of the blowing component 500 can cover one end of the second heat dissipation part 420. It should be noted that the cross-section of the air outlet 530 and the cross-section of the second heat dissipation part 420 can both be perpendicular to the length direction of the horizontal section 5222 described above and parallel to the direction from the second heat dissipation fin 422 to the laser module 300.
[0066] In an alternative embodiment, a limiting groove 424 can be provided on the radiator 400, and the laser module 300 can be embedded in the limiting groove 424. In this way, the limiting groove 424 can play a role in limiting the laser module 300, and when installing the laser module 300, the limiting groove 424 can play a role in pre-fixing the laser module 300 to facilitate the installation of the laser module 300.
[0067] Moreover, the laser module 300 can be connected to the bottom of the limiting groove 424 through a fixing member, which can improve the fixing stability of the laser module 300.
[0068] In other embodiments, the limiting groove 424 may not be provided on the radiator 400, and the laser module 300 can be connected to the radiator 400 only through a fixing member. Here, the fixing member can be a screw.
[0069] Optionally, two limiting portions 423 may be provided on the second heat dissipation substrate 421. A limiting groove 424 as described above may be formed between the two limiting portions 423 and the second heat dissipation substrate 421. Moreover, two ends of the laser module 300 may be respectively attached to the two limiting portions 423. In this way, the two limiting portions 423 can play a role in pre-fixing the laser module 300.
[0070] In an alternative embodiment of the present application, the cleaning device may further include a main board 200. The main board 200 may be located in the main machine cavity 140, and the laser module 300 and the main board 200 may be arranged at intervals. In this way, the influence of the temperature of the main board 200 on the temperature of the laser module 300 can be reduced, so as to further improve the heat dissipation effect of the laser module 300.
[0071] It should be noted that the laser module 300 may be electrically connected to the main board 200 through a wire to ensure communication between the laser module 300 and the main board 200.
[0072] In other embodiments, the laser module 300 and the main board 200 may also not be arranged at intervals. Specifically, the laser module 300 may be directly connected to the main board 200.
[0073] In an alternative embodiment, the device body 100 may include a housing 110 and a heat conduction cover plate 120. The heat conduction cover plate 120 may be connected to the housing 110. Here, the connection between the housing 110 and the heat conduction cover plate 120 may form the main machine cavity 140. Moreover, the main board 200 may be connected to the heat conduction cover plate 120 through a heat conduction bracket 210. In this way, the heat of the main board 200 can be transferred to the heat conduction cover plate 120 through the heat conduction bracket 210 and dissipated through the heat conduction cover plate 120, thereby reducing the temperature of the main board 200. Here, the heat conduction cover plate 120 may be a metal cover plate to facilitate heat conduction.
[0074] In addition, the radiator 400 may be connected to the side wall of the housing 110 away from the heat conduction cover plate 120, and the laser module 300 may be located on the side of the radiator 400 facing away from the main board 200. In this way, the laser module 300 can be kept away from the main board 200, so as to further reduce the influence of the temperature of the main board 200 on the temperature of the laser module 300.
[0075] Optionally, the housing 110 may include a top cover 111, a front cover plate 112, a front housing 113, and a bottom housing 114. The top cover 111 may be connected to the top ends of the heat-conducting cover plate 120 and the front housing 113. The bottom housing 114 may be connected to the bottom ends of the heat-conducting cover plate 120 and the front housing 113. The top end of the front cover plate 112 may be connected to one end of the top cover 111 away from the heat-conducting cover plate 120. The bottom end of the front cover plate 112 may be connected to the front housing 113. Both sides of the front cover plate 112 may be connected to the front housing 113, and the front cover plate 112 may be located on the side of the housing 110 away from the heat-conducting cover plate 120. Here, the connection of the top cover 111, the front cover plate 112, the front housing 113, the bottom housing 114, and the heat-conducting cover plate 120 may form a main machine compartment 140, and the radiator 400 may be connected to the front cover plate 112.
[0076] In some embodiments, an operation panel may be provided on the front cover plate 112. For the convenience of user operation, the front cover plate 112 may be inclined so that the operation panel is inclined.
[0077] In addition, the cleaning device may further include a bumper 130. The bumper 130 may be disposed around a part of the outer side of the front housing 113 and may be disposed near the bottom of the front housing 113. In this way, during the operation of the cleaning device, when the bumper collides with furniture or other obstacles, a collision signal is triggered, causing the cleaning device to change its movement path, thereby protecting the cleaning device and household items from damage. Here, a sensor for detecting obstacles may be provided on the bumper 130 for emitting a collision signal.
[0078] Optionally, the cleaning device may be a floor washer. Of course, the cleaning device may also be a sweeping robot or other intelligent cleaning devices.
