[0002] The detachable tower fan includes an upper structure and a lower structure, and the upper structure and the lower structure are detachably connected, so that the user can remove the upper structure separately for cleaning. After some users have finished cleaning the upper structure, they reinstall the upper structure onto the lower structure when the moisture in the upper structure has not completely dried, that is, when there is still residual water. The residual water in the upper structure flows to the motor, circuit board and other components of the lower structure under the action of gravity, which can easily cause malfunctions. For this reason, the lower structure needs to be provided with a protective structure for components such as motors and circuit boards, so as to form a relatively closed protection for components such as motors and circuit boards, but this design can easily make it difficult for heat to dissipate.

[0040] The present application discloses a tower fan, combined with Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments of the present application, the tower fan includes an upper body 100 and a lower body 200, the upper body 100 includes a wind wheel 2000, the lower body 200 is arranged below the upper body 100, and the lower body 200 is detachably connected to the upper body 100, and the user can separate the upper body 100 from the lower body 200 when cleaning the upper body 100, and the lower body 200 includes a motor 4000 and a protective cover 3000, wherein the motor 4000 is used to be driven and connected to the wind wheel 2000, and the protective cover 3000 covers the motor 4000 to protect the motor 4000, and the protective cover 3000 is provided with a first heat dissipation hole 3210.

[0041] Through the detachable connection between the upper body 100 and the lower body 200, the upper body 100 can be removed separately for cleaning, which is convenient and quick. By setting the protective cover 3000, the protective cover 3000 forms protection for the motor 4000 to prevent the residual water in the upper body 100 from flowing to the motor 4000 and causing the motor 4000 to malfunction when the upper body 100 is installed on the lower body 200 after cleaning. The protective cover 3000 realizes heat dissipation for the motor 4000 by setting the first heat dissipation hole 3210 to prevent heat accumulation from affecting the performance of the motor 4000.

[0042] Specifically, the up, down, left, right, front and back directions in this article are based on the tower fan placed on the ground. The side of the tower fan facing the user is the front, and the side away from the user is the back. The side corresponding to the user's left hand is the left, and the side corresponding to the user's right hand is the right. The side close to the ground is the bottom, and the side away from the ground is the top.

[0043] The lower fuselage 200 is equivalent to forming a base. When the tower fan is placed on the ground, the lower fuselage 200 contacts the ground to support the entire tower fan. In addition to the motor 4000 and the protective cover 3000, the lower fuselage 200 may also include a shell 3700, an electric control component, etc. The shell 3700 forms the surface of the lower fuselage 200, the motor 4000, the electric control component, etc. are arranged in the shell 3700, and the protective cover 3000 covers the motor 4000 to protect the motor 4000. The upper fuselage 100 is installed above the lower fuselage 200. The upper fuselage 100 includes an air duct 1000, a wind wheel 2000, etc. The wind wheel 2000 can be rotatably installed in the air duct 1000, and the wind wheel 2000 needs to be connected to the motor 4000.

[0044] When the tower fan is working, the motor 4000 can drive the wind wheel 2000 to rotate in the air duct 1000, so as to realize the air supply of the upper body 100. Therefore, after a period of use, the upper body 100 is easy to accumulate dust and become dirty. For this reason, the upper body 100 and the lower body 200 are designed to be detachably connected. The so-called detachable connection means that when the upper body 100 and the lower body 200 need to be assembled together, the upper body 100 and the lower body 200 are fixed together, and the wind wheel 2000 and the motor 4000 are driven to connect, and the motor 4000 can drive the wind wheel 2000 to rotate. When the upper body 100 needs to be disassembled relative to the lower body 200, the upper body 100 can be disassembled separately, and the wind wheel 2000 and the motor 4000 are disconnected from the driving connection. The upper body 100 that is disassembled separately can be cleaned. Especially when all the electrical components are arranged on the lower body 200, the upper body 100 can be completely immersed in water for cleaning, which is more convenient and quick.

[0045] It is understandable that since the upper body 100 includes the air duct 1000 and the wind wheel 2000, the internal structure is relatively complex. After the upper body 100 is cleaned, there may be residual water in the upper body 100 (there is residual water in both the air duct 1000 and the wind wheel 2000). The user may install the upper body 100 on the lower body 200 before the upper body 100 is dry. In this case, the residual water in the upper body 100 will flow downward to the motor 4000 under the action of gravity, which may easily cause the motor 4000 to malfunction.

[0046] To this end, in this embodiment, a protective cover 3000 is provided, and the protective cover 3000 covers the motor 4000. It can be understood that since the motor 4000 needs to be connected to the wind wheel 2000 for driving, the protective cover 3000 needs to avoid the driving connection between the motor 4000 and the wind wheel 2000. By providing the protective cover 3000, when residual water on the upper fuselage 100 drips downward, it can be blocked by the protective cover 3000, thereby reducing the residual water from flowing to the motor 4000 and causing the motor 4000 to fail. The protective cover 3000 can be made of metal material, plastic material or other materials, and can be an integrated structure or a split structure connected to each other. In order to meet different installation requirements, the protective cover 3000 can be an irregular shape or a regular shape. The protective cover 3000 can be fixed to the housing 3700 to cover the motor 4000. The protective cover 3000 can also be screwed to the motor 4000 through the connecting column, and the motor 4000 can be installed in the housing 3700, thus completing the assembly of various components.

[0047] Furthermore, although the design of the protective cover 3000 can prevent water from flowing from the upper body 100 to the motor 4000, the design of the protective cover 3000 will also affect the heat dissipation of the motor 4000. Since the protective cover 3000 covers the motor 4000, the heat of the motor 4000 cannot be dissipated in time, which will affect the performance of the motor 4000. For this reason, in this embodiment, by providing a first heat dissipation hole 3210 on the protective cover 3000, the first heat dissipation hole 3210 may include a plurality of first heat dissipation holes 3210, and the first heat dissipation holes 3210 are connected to the inside and outside of the protective cover 3000, the heat of the motor 4000 can be dissipated through the first heat dissipation holes 3210, and the heat accumulation is avoided to affect the performance of the motor 4000.

[0048] Combination Figure 8 As shown, in some embodiments of the present application, the protective cover 3000 includes a through hole 3100 and a water guide plate 3200. The water guide plate 3200 surrounds the through hole 3100 and is used to receive water dripping downward from the upper fuselage 100 and can guide the water away, while the through hole 3100 is used to avoid the driving connection between the wind wheel 2000 and the motor 4000. Through such an arrangement, the water dripping from the upper fuselage 100 can be quickly drained away.

[0049] Specifically, the through hole 3100 of the protective cover 3000 is a through hole structure, connecting the upper and lower spaces. As can be seen from the above, the motor 4000 needs to be connected to the wind wheel 2000 by driving, so the through hole 3100 is provided on the protective cover 3000 to form a avoidance, so that the motor 4000 can be connected to the wind wheel 2000 by driving. That is, the output shaft of the motor 4000 can pass through the through hole 3100 to be connected to the wind wheel 2000 by driving, or the structure on the wind wheel 2000 can pass through the through hole 3100 to be connected to the motor 4000 by driving, or the structure that realizes the driving connection between the motor 4000 and the wind wheel 2000 passes through the through hole 3100. On this basis, the water guide plate 3200 of the protective cover 3000 surrounds the through hole 3100, and the water guide plate 3200 is roughly located at the top (upper position) of the protective cover 3000 and is relatively close to the upper fuselage 100. In this way, when water on the upper fuselage 100 drips downward to the water guide plate 3200, the water guide plate 3200 receives the dripping water and guides the water away. The setting of the water guide plate 3200 increases the water discharge speed.

[0050] Combination Figure 1As shown, in some embodiments of the present application, the water guide plate 3200 is provided with a drain port 3230, and the water guide plate 3200 guides the received water specifically through the drain port 3230, so that the orderly flow of water can be achieved, the disordered flow of water can be avoided, and the water discharge efficiency is higher. Specifically, when the water of the upper fuselage 100 drips toward the water guide plate 3200, the water will flow along the water guide plate 3200. In this embodiment, by providing the drain port 3230, the water guide plate 3200 can restrict the flow of the water, so that the water is collected in the drain port 3230 and then discharged through the drain port 3230, avoiding the disordered flow of water, and making it more convenient to discharge the water to the target area.

[0051] For example, the edge of the water guide plate 3200 is provided with a ridge 3220, and there are a plurality of ridges 3220, which are arranged alternately along the edge of the water guide plate 3200, and a drain port 3230 is formed between adjacent ridges 3220. The edge of the water guide plate 3200 is provided with a ridge 3220, that is, the ridge 3220 is located around the water guide plate 3200, and water will encounter obstruction of the ridge 3220 when flowing along the water guide plate 3200, and the ridge 3220 blocks the water and causes the water to change direction. Since the drain port 3230 is formed between adjacent ridges 3220, the water that encounters the obstruction of the ridge 3220 and changes direction is then discharged from the water guide plate 3200 through the drain port 3230.

[0052] Combination Figure 1 As shown, in some embodiments of the present application, the water guide plate 3200 is designed to be inclined from top to bottom. It can be understood that as long as the water guide plate 3200 is inclined downward relative to the horizontal plane, the angle of inclination is not limited. By designing the water guide plate 3200 to be inclined, when the water guide plate 3200 receives dripping water, the water can flow downward along the water guide plate 3200 under the action of gravity, so that the water can be drained away more quickly. For example, water flows quickly along the surface of the water guide plate 3200 to the drain port 3230 under the action of gravity and is discharged from the water guide plate 3200.

[0053] Since the water guide plate 3200 surrounds the via hole 3100, water moves away from the via hole 3100 while being discharged along the water guide plate 3200, thereby preventing water from penetrating into the motor 4000 through the via hole 3100. In this way, there is no need to perform sealing treatment on the edge of the via hole 3100.

[0054] Combination Figure 1 As shown, in some embodiments of the present application, the first heat dissipation hole 3210 is disposed on the water guide plate 3200, and the aperture of the first heat dissipation hole 3210 is designed to be no greater than 1.5 mm.

[0055] In this embodiment, the first heat dissipation hole 3210 is designed on the water guide plate 3200. As mentioned above, the water guide plate 3200 is closer to the upper fuselage 100 to receive water dripping from the upper fuselage. The airflow caused by the wind wheel can pass through the first heat dissipation hole 3210 to enhance the heat dissipation effect (detailed below). Therefore, in order to prevent water from entering the interior of the protective cover 3000 through the first heat dissipation hole 3210 and then flowing to the motor 4000, the aperture of the first heat dissipation hole 3210 is optimized and designed to be no larger than 1.5 mm. For example, the aperture of the first heat dissipation hole 3210 is 0.2 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm or 1.5 mm. Since water has surface tension, by optimizing the aperture of the first heat dissipation hole 3210, under the action of surface tension, when water flows through the first heat dissipation hole 3210, it will not flow into the interior of the protective cover 3000 through the first heat dissipation hole 3210, but will continue to flow along the surface of the protective cover 3000 to the target area. In this way, the heat dissipation demand of the motor 4000 can be met and water can be prevented from entering the motor 4000. .

[0056] Continue to combine Figure 8 As shown, in some embodiments of the present application, the protective cover 3000 includes a side surrounding structure 3300, wherein the side surrounding structure 3300 is designed to extend downward from the water guide plate 3200, so that the side surrounding structure 3300 is in a state of surrounding the water guide plate 3200, and the side surrounding structure 3300 is provided with a drainage channel 3310, and the water guide plate 3200 can guide water to the drainage channel 3310. By such a configuration, the heat dissipation area can be effectively increased, and the heat dissipation effect of the motor 4000 can be improved.

[0057] Specifically, the side enclosure structure 3300 extends downward from the water guide plate 3200, so that the water guide plate 3200 and the side enclosure structure 3300 bulge upward as a whole. In this way, the side enclosure structure 3300 provides a basis for further heat dissipation, and by providing a discharge channel 3310 on the side enclosure structure 3300, water flowing out of the discharge port 3230 is discharged downward along the discharge channel 3310, and the flow of water continues to be constrained through the discharge channel 3310 until it is discharged from the discharge channel 3310.

[0058] Combination Figure 1 As shown, in some embodiments of the present application, the side surrounding structure 3300 is provided with a second heat dissipation hole 3320, and the heat dissipation effect is further enhanced through the second heat dissipation hole 3320. As mentioned above, the overflow channel 3310 of the side surrounding structure 3300 receives the water discharged from the water guide plate 3200, and the overflow channel 3310 restricts the flow of this part of the water so that the water does not flow to the second heat dissipation hole 3320.

[0059] For example, the water guide plate 3200 is provided with a ridge 3220 around it, and the adjacent ridges 3220 form a drain port 3230, and the second heat dissipation hole 3320 is specifically located below the ridge 3220. The water flowing on the water guide plate 3200 encounters the ridge 3220 blocking and changes direction, and then enters the drain channel 3310 through the drain port 3230, and continues to flow along the drain channel 3310. Through the blocking of the ridge 3220 and the restraining effect of the drain channel 3310, the water will not enter the inside of the protective cover 3000 through the second heat dissipation hole 3320, thereby preventing the motor 4000 from malfunctioning. The cooperation between the first heat dissipation hole 3210 and the second heat dissipation hole 3320 realizes heat dissipation over a larger area, further improving the heat dissipation effect of the motor 4000.

[0060] Continue to combine Figure 8 As shown, in some embodiments of the present application, the aperture of the second heat dissipation hole 3320 is designed to be larger than the aperture of the first heat dissipation hole 3210, so that the heat dissipation of the motor 4000 can be further improved. It can be understood that through the cooperation of the ridge 3220, the drain port 3230 and the side surrounding structure 3300 mentioned above, the water flowing along the water guide plate 3200 will not flow to the side surrounding structure 3300 located below the ridge 3220, so that the second heat dissipation hole 3320 can be designed to be larger, and a stronger airflow is formed in the second heat dissipation hole 3320 than in the first heat dissipation hole 3210, thereby enhancing the heat dissipation of the motor 4000.

[0061] Combination Figure 7 and Fig. 9 As shown, in some embodiments of the present application, the protective cover 3000 includes a panel 3400, wherein the panel 3400 is designed to surround the side surrounding structure 3300, so that a cavity 3500 is enclosed between the panel 3400 and the side surrounding structure 3300, and the leakage channel 3310 needs to be designed to be connected with the cavity 3500, and the cavity 3500 is used to receive water flowing down from the leakage channel 3310. The cavity 3500 is provided with a leakage hole 3510 at the bottom of the cavity 3500, and the leakage hole 3510 is designed to be connected with the outer side of the panel 3400, so that water can be discharged and flow to the surface of the lower fuselage 200. Through such a design, the water dripping from the upper fuselage 100 toward the protective cover 3000 is discharged to the surface of the lower fuselage 200, and the water flows to the ground along the surface of the lower fuselage 200 under the action of gravity, which is convenient for users to wipe.

[0062] Specifically, when water leaves the leakage channel 3310, disordered flow may occur, which is not convenient for handling the water. For this reason, in this embodiment, the enclosure 3400 is designed, and the enclosure 3400 surrounds the side enclosure structure 3300 to enclose a cavity 3500. The water that leaves the leakage channel 3310 enters the cavity 3500 and is temporarily stored in the cavity 3500, thereby preventing the water that leaves the leakage channel 3310 from flowing unnecessarily. When the upper body 100 is installed on the lower body 200, the upper body 100 blocks the protective cover 3000. Therefore, the water in the cavity 3500 cannot be stored for a long time. Therefore, a leakage hole 3510 is designed at the bottom of the cavity 3500 (the bottom of the cavity is also a part of the protective cover 3000). The water entering the cavity 3500 is discharged from the cavity 3500 through the leakage hole 3510 to prevent water from accumulating in the cavity 3500. When the water is discharged from the leakage hole 3510, it flows to the surface of the lower body 200, such as the surface of the outer shell 3700 mentioned above.

[0063] For example, the protective cover 3000 is protruding above the housing 3700, and the leakage hole 3510 is arranged close to the surface of the housing 3700, so that the water flowing out of the leakage hole 3510 flows downward along the surface of the housing 3700 under the action of gravity until it flows to the ground, and the user can wipe the water flowing to the ground. It can be understood that since the side surrounding structure 3300 is provided with the second heat dissipation hole 3320, and the water that escapes from the leakage channel 3310 enters the cavity 3500, in order to prevent the water entering the cavity 3500 from flowing to the motor 4000 through the second heat dissipation hole 3320, the second heat dissipation hole 3320 needs to be designed to be a certain distance away from the bottom of the side surrounding structure 3300.

[0064] In some embodiments of the present application, the enclosure 3400 is plugged into the bottom of the air duct 1000 and achieves surface contact with the bottom of the air duct 1000, thereby increasing the stability of the detachable connection between the upper fuselage 100 and the lower fuselage 200.

[0065] Specifically, as mentioned above, the upper body 100 and the lower body 200 are detachably connected, and it is particularly important to ensure the stability of the upper body 100 and the lower body 200 when they are reinstalled after disassembly. In this embodiment, the panel 3400 is inserted into the bottom of the air duct 1000, that is, since the upper body 100 and the lower body 200 are distributed in the up-down direction, the panel 3400 is roughly plugged into the bottom of the air duct 1000 along the up-down direction. Through such a setting, the panel 3400 is in contact with the bottom surface of the air duct 1000. Along the up-down direction, there is a certain overlap between the air duct 1000 and the protective cover 3000, which constrains each other, plays a role in preliminary positioning, and can avoid the upper body 100 and the lower body 200 from being skewed, thereby ensuring the driving connection between the motor 4000 and the wind wheel 2000. It can be understood that, in the upper fuselage 100 , except for the wind wheel 2000 , the frame supporting the wind wheel 2000 can be regarded as the air duct 1000 .

[0066] Combination Figure 7 As shown, in some embodiments of the present application, the protective cover 3000 includes a connecting seat 3600, and the side enclosure structure 3300 and the enclosure plate 3400 mentioned above are both arranged on the connecting seat 3600. It can be understood that since the side enclosure structure 3300 extends downward from the water guide plate 3200, that is to say, the water guide plate 3200 is also arranged on the connecting seat 3600, the connecting seat 3600 is arranged in cooperation with the air duct 1000 to realize the detachable connection between the lower fuselage 200 and the upper fuselage 100.

[0067] Specifically, the connection seat 3600 of the protective cover 3000 can be fixed to the housing 3700, so that the installation of the protective cover 3000 is realized, so that the protective cover 3000 covers the motor 4000. The water guide plate 3200, the side surrounding structure 3300, the enclosure 3400 and the connection seat 3600 can be integrally injection molded, so as to enhance the structural strength of the protective cover 3000. Through the design of the connection seat 3600 of the protective cover 3000, when the upper body 100 is installed on the lower body 200, the air duct 1000 of the upper body 100 and the connection seat 3600 of the protective cover 3000 are detachably connected, thereby realizing the detachable connection between the upper body 100 and the lower body 200. When the air duct 1000 is connected to the connection base 3600, the upper body 100 and the lower body 200 can be connected and fixed, and when the air duct 1000 is detached from the connection base 3600, the upper body 100 and the lower body 200 can be separated. It can be understood that other components of the upper body 100 can be fixed to the air duct 1000, and other components of the lower body 200 can be fixed to the protective cover 3000, so that when the air duct 1000 is connected to the connection base 3600, the upper body 100 and the lower body 200 can be detachably connected. For example, the upper body 100 also includes an outer shell, and the outer shell of the upper body 100 is connected and fixed to the air duct 1000, and the wind wheel 2000 can be rotatably installed on the air duct 1000, thus forming a whole. When the air duct 1000 and the connecting seat 3600 are connected, the air duct 1000 is fixed, that is, the outer shell of the upper body and the wind wheel 2000 are fixed, that is, the upper body 100 is fixed to the lower body 200.

[0068] Furthermore, combined with Figure 7 and Fig.10 As shown, the connection base 3600 is provided with a buckle 3610, and the connection base 3600 is detachably connected to the air duct 1000 through the buckle 3610. The buckle 3610 is convenient for both fixing and separating the two objects. As mentioned above, the protective cover 3000 needs to be provided with a leakage hole 3510 to discharge water to the outside, but the structural strength of the corresponding position after the leakage hole 3510 is provided will be reduced. For this reason, in this embodiment, the leakage hole 3510 is designed to be connected with the position where the buckle 3610 is located. Since the buckle 3610 is provided, the structural strength of the position corresponding to the buckle 3610 is higher. For example, the buckle 3610 is provided around the connecting seat 3600, and the structural strength of the position where the buckle 3610 is provided on the connecting seat 3600 is higher. By connecting the leakage hole 3510 to the position where the buckle 3610 is located, for example, the leakage hole 3510 is exposed in the buckle 3610, when water flows out through the leakage hole 3510, it flows downward along the buckle 3610 to the surface of the lower fuselage 200 (the surface of the outer shell 3700). In this way, water discharge can be achieved and the decrease in structural strength caused by the leakage hole 3510 is avoided.

[0069] Combination Figure 2 , Figure 5 and Figure 6 As described above, in some embodiments of the present application, the space covered by the protective cover 3000 is connected to the space enclosed by the outer shell 3700 , and the outer shell 3700 is provided with a vent hole 3710 , thereby enhancing the heat dissipation of the motor 4000 .

[0070] Specifically, the first heat dissipation hole 3210 and the second heat dissipation hole 3320 of the protective cover 3000 are connected to the space enclosed by the protective cover 3000, the vent hole 3710 of the outer shell 3700 is connected to the space enclosed by the outer shell 3700, and the space enclosed by the protective cover 3000 is connected to the space enclosed by the outer shell 3700. Then the first heat dissipation hole 3210 and the second heat dissipation hole 3320 are connected to the vent hole 3710 respectively. In this way, air can flow from the first heat dissipation hole 3210 and the second heat dissipation hole 3320 to the vent hole 3710, and also flow from the vent hole 3710 to the first heat dissipation hole 3210 and the second heat dissipation hole 3320, thereby enhancing the heat dissipation of the motor 4000.

[0071] Combination Figure 3 and Figure 4 As shown, in some embodiments of the present application, the air duct 1000 is provided with a connecting hole 1100, specifically, the bottom of the air duct 1000 is provided with a connecting hole 1100, and the internal space of the air duct 1000 and the space between the air duct 1000 and the protective cover 3000 are suitable for being connected through the connecting hole 1100, so that the heat dissipation of the motor 4000 can be further enhanced.

[0072] Specifically, when the tower fan is running, the wind wheel 2000 rotates in the air duct 1000 (that is, the wind wheel 2000 rotates in the internal space of the air duct 1000), and the upper body 100 is provided with an air inlet and an air outlet (not shown in the figure). The rotation of the wind wheel 2000 drives the air flow to enter from the air inlet and be discharged from the air outlet. In this process, the wind wheel 2000 can also drive the air flow to enter the space enclosed by the outer shell 3700 from the air vent 3710 (of course, if the air vent 3710 is not provided, the air flow can also enter the lower body 200 from the gap of the lower body 200), and then flow through the space enclosed by the protective cover 3000, the first heat dissipation hole 3210 and the second heat dissipation hole 3320, the space between the protective cover 3000 and the air duct 1000, and the connecting hole 1100 in turn, and finally enter the air duct 1000, and then be discharged through the air outlet. In this process, the airflow flows through the motor 4000, taking away the heat of the motor 4000, and further realizing the heat dissipation of the motor 4000. Since the airflow driven by the wind wheel 2000 can flow through the first heat dissipation hole 3210, the aperture design requirements of the first heat dissipation hole 3210 are higher. By designing the aperture of the first heat dissipation hole 3210 to be no more than 1.5 mm, the requirements of waterproofing and airflow can be met. It can be understood that since the connecting hole 1100 is provided, the water in the upper fuselage 100 can drip into the protective cover 3000 through the connecting hole 1100. Since the wind wheel 2000 and the motor 4000 need to be driven and connected, the connecting hole 1100 is located around the connection between the wind wheel 2000 and the motor 4000, so that the water dripping through the connecting hole 1100 will not drip onto the through hole 3100 of the protective cover 3000.
