Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a humidifier and a cooling fan. Background Technology

[0002] An air cooler is a device that combines functions such as air delivery, cooling, air purification, and air humidification. The air cooler uses a water pump to send water from the water tank to the evaporator. The fan drives the air through the evaporator and carries the moisture, using the principle of water evaporation to absorb heat and achieve the effect of cooling and humidification.

[0003] Because air coolers need to carry components such as water tanks, evaporators, and fans, they are relatively large and heavy. This makes them inconvenient to move and can only be used in a fixed working area indoors or outdoors, resulting in low efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a humidifier and a cooling fan to address the problem of low efficiency in the use of cooling fans.

[0005] A humidifier, comprising:

[0006] Evaporation bracket, wherein the evaporation bracket is provided with an air inlet channel;

[0007] A wet curtain is installed inside the air inlet channel;

[0008] The evaporation bracket is provided with a mounting position for mounting the fan body, and the fan is detachably mounted on the mounting position. When the fan body is mounted on the mounting position, the air inlet of the fan is connected to the air inlet channel. In one embodiment, the humidifier further includes a water tank, and the evaporation bracket is disposed on the water tank. When the fan body is mounted on the mounting position, the fan body is supported on the water tank.

[0009] In one embodiment, a water pump is installed inside the water tank, and the outlet of the water pump is connected to the air inlet channel of the evaporation bracket;

[0010] The water tank is provided with a power terminal, which is electrically connected to the water pump. The fan body is provided with a power interface. When the fan body is installed in the mounting position, the power interface contacts and is electrically connected to the power terminal.

[0011] In one embodiment, the top of the water tank has an opening that connects to the interior of the water tank. The interior of the water tank is provided with multiple support members, all of which are located in the opening. When the fan body is installed in the mounting position, the fan body is supported by the multiple support members through the opening.

[0012] In one embodiment, the top of the water tank has an opening that connects to the interior of the water tank, through which the evaporation bracket can enter the interior of the water tank.

[0013] In one embodiment, the humidifier further includes multiple limiting members installed on the water tank. Each limiting member includes a first state and a second state. When all the limiting members are in the first state, the limiting members block the opening to prevent the evaporation bracket from entering the interior of the water tank.

[0014] When all the limiting members are in the second state, the limiting members avoid the opening, and the evaporation bracket can enter the interior of the water tank through the opening.

[0015] In one embodiment, the limiting member includes a fixed part and an elastic part connected to each other, the fixed part being fixedly installed on the water tank;

[0016] When the limiting member is in the first state, the elastic part abuts against the evaporator bracket and supports the evaporator bracket; when the limiting member is in the second state, the elastic part elastically deforms in the direction of avoiding the evaporator bracket.

[0017] In one embodiment, each of the elastic portions is provided with an elastic inclined surface and an elastic plane that are continuous with each other. The elastic inclined surface is inclined relative to the plane where the opening is located, and the elastic plane is parallel to the plane where the opening is located.

[0018] The evaporation support is also provided with a plurality of lugs corresponding one-to-one with a plurality of limiting members. Each lug is provided with a continuous supporting plane and a supporting inclined surface. When the limiting member is in the first state, the supporting plane of each lug is parallel to and abuts against the elastic plane of the corresponding limiting member, and the supporting inclined surface of the lug intersects with and abuts against the elastic inclined surface of the corresponding limiting member.

[0019] In one embodiment, the evaporator bracket is configured to form a receiving cavity and has an installation port communicating with the receiving cavity, through which the fan body can enter the receiving cavity.

[0020] In one embodiment, the air inlet is located within the accommodating cavity, and both the air inlet channel and the wet curtain surround the accommodating cavity.

[0021] In one embodiment, a water tank is provided on the top of the evaporation bracket, and a water inlet is connected to the water tank;

[0022] The evaporation bracket is also provided with multiple drain outlets, each of which is connected to the water tank and the air inlet channel.

[0023] In one embodiment, the bottom of the evaporation bracket is provided with a fixed opening that communicates with the air inlet channel, and the wet curtain can enter the air inlet channel through the fixed opening;

[0024] The bottom of the evaporator is also provided with multiple baffles, which are located inside the fixing port to prevent the wet curtain from passing through the fixing port.

[0025] A cooling fan includes a fan body and a humidifying component as described above.

[0026] The aforementioned air cooler can be mounted on a humidifier to function as an air cooler when the user needs cooling or humidification. The fan's air inlet connects to the air intake channel with the evaporative cooling pad, allowing the exhaust air to be humidified and cooled by the pad, thus achieving the desired cooling and humidifying effect. When the user only needs airflow or needs to leave the air cooler's operating area, the fan can be detached from the humidifier and used as a regular fan. Because it's detached, the fan's smaller size makes it easy to carry. This allows the user to continue using the fan even when away from its operating area, significantly improving its efficiency.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] See Figure 1 , Figure 2 and Figure 8 An embodiment of this application provides a cooling fan including a humidifier 100 and a fan body 200. The humidifier 100 includes an evaporator bracket 110 and a wet curtain 111. The evaporator bracket 110 has an air inlet channel 112, and the wet curtain 111 is disposed in the air inlet channel 112.

[0051] The fan body 200 has an air inlet 210, an air outlet 220, and fan blades 250 disposed between the air inlet 210 and the air outlet 220. When the fan blades 250 rotate, the fan body 200 draws air from the air inlet 210, passes it through the fan blades 250, and then discharges the airflow from the air outlet 220. The evaporator bracket 100 is provided with a mounting position 101 for mounting the fan body 200, and the fan body 200 is detachably mounted on the mounting position 101 of the humidifier 100. When the fan body 200 is mounted on the mounting position 101 of the humidifier 100, the air inlet 210 is connected to the air inlet channel 112.

[0052] When the fan body 200 is installed on the humidifier, the fan blades 250 of the fan body 200 are rotated. The air drawn by the fan body 200 will enter the air inlet 210 after passing through the air inlet channel 112. When the air passes through the air inlet channel 112, it will pass through the wet curtain 111 located in the air inlet channel 112. When the air passes through the wet curtain 111, the moisture inside the wet curtain 111 evaporates and absorbs heat, thereby reducing the temperature of the air passing through the wet curtain 111. Finally, the air discharged from the air outlet 220 can cool the surrounding environment.

[0053] When the fan body 200 is detached from the humidifier 100, it can still draw air from the inlet 210 and exhaust air from the outlet 220 via the fan blades 250. In this case, the fan body 200 can still be used as a regular fan; however, since the drawn-in air does not pass through the evaporative cooling pad 111, it has no cooling effect. The detachment of the fan body 200 from the humidifier 100 makes it smaller and easier to carry. Even after leaving the operating range of the air cooler, the user can still detach the fan body 200 from the humidifier 100 and use it as a regular fan, greatly improving the efficiency of the air cooler.

[0054] When the user needs cooling or humidification, the aforementioned air cooler can be mounted on the humidifier 100 to form an air cooler. The air inlet 210 of the fan body 200 is connected to the air inlet channel 112 equipped with the evaporative cooling pad 111. The air exhausted from the fan body 200 is then humidified and cooled by the evaporative cooling pad 111, thus achieving the cooling and humidifying effects. When the user only needs airflow or needs to leave the working area of ​​the air cooler, the fan body 200 can be detached from the humidifier 100 and used as a regular fan. Because the fan body 200 is detached from the humidifier 100, its smaller size makes it easy to carry. Thus, even if the operator leaves the working area of ​​the air cooler, they can still use the fan body 200 for ventilation, greatly improving the efficiency of the air cooler.

[0055] In the embodiments of this application, see Figure 2 , Figure 3 and Figure 4 The humidifier 100 also includes a water tank 120, and an evaporator bracket 110 is mounted on the water tank 120. When the fan body 200 is installed in the mounting position 101, the fan body 200 is supported on the water tank 120. In actual use, the water tank 120 is used to store a certain amount of clean water for humidifying the aforementioned wet curtain 111. Therefore, the volume of the water tank 120 is usually larger than the volume of the evaporator bracket 110 and the fan body 200. Therefore, by mounting both the evaporator bracket 110 and the fan body 200 on the water tank 120 and supporting them with the water tank 120, the installation reliability of the evaporator bracket 110 and the fan body 200 can be improved.

[0056] Optionally, both the mounting bracket and the fan body 200 can be mounted on the top of the water tank 120 to raise the height of the fan body 200 via the water tank 120. In other embodiments, the mounting bracket and the fan body 200 can also be mounted on the side wall of the water tank 120.

[0057] It should be noted that the mounting bracket and the fan body 200 can also be mounted on the water tank 120 with only the mounting bracket, while the fan body 200 can be directly and detachably mounted on the mounting bracket. The mounting positions 101 of the mounting bracket and the fan body 200 can be selected according to the actual use situation, and are not limited here.

[0058] In some embodiments, a water pump 121 is provided inside the water tank 120. The outlet of the water pump 121 is connected to the air inlet channel 112 of the evaporation bracket 110 so that the water pump 121 can draw clean water from inside the water tank 120 and deliver it into the air inlet channel 112, thereby wetting the wet curtain 111 located in the air inlet channel 112, so that the wet curtain 111 is always kept moist.

[0059] Among them, see Figure 2 and Figure 9 The water tank 120 is equipped with a power terminal 122, which is electrically connected to the water pump 121. The fan body 200 is equipped with a power interface 230. When the fan body 200 is installed on the mounting position 101, the power interface 230 contacts and is electrically connected to the power terminal 122. Thus, when the operator installs the fan body 200 on the mounting position 101 of the humidifier 100, the connection between the power terminal 122 and the power interface 230 allows the water pump 121 to be electrically connected to the fan body 200. This not only allows the water pump 121 to draw power from the fan body 200, but also allows the fan body 200 to control the working state of the water pump 121 to draw clean water and deliver it into the air inlet channel 112 according to the user's needs. For example, when the user only needs the blowing mode, the fan body 200 controls the water pump 121 to be in a non-working state. However, if the user needs the cooling or humidifying mode, the fan body 200 can control the water pump 121 to work, so that the water pump 121 continuously pumps water into the air intake channel, so that the wet curtain 111 is always kept moist.

[0060] When the operator removes the fan body 200 from the water tank 120, the power terminal 122 and the power interface 230 are disconnected, so the water pump 121 cannot draw power from the fan body 200 and is in a de-energized state, thus stopping the water supply to the air intake channel. In this way, when the operator removes the fan body 200 from the water tank 120, the water pump 121 automatically shuts off, achieving the effect of saving energy.

[0061] In some specific embodiments, the top of the water tank 120 is provided with an opening 123 that communicates with the interior of the water tank 120, and the interior of the water tank 120 is provided with multiple support members 124, all of which are located in the opening 123. When the fan body 200 is installed on the mounting position 101, the fan body 200 is supported by the multiple support members 124 through the opening 123, so that the fan body 200 can be installed on the water tank 120.

[0062] Once the fan body 200 is detached from the water tank 120, the opening 123 is no longer blocked by the fan body 200. At this time, the user can add water to the water tank 120 through the opening 123, or empty the water in the water tank 120 through the opening 123, so as to move the cooling fan.

[0063] Furthermore, a power terminal 122 is provided on the top of one of the support members 124, and a power interface 230 is provided on the bottom of the fan body 200. Thus, when the fan body 200 is placed on multiple support members 124, the power terminal 122 will contact and connect electrically with the power interface 230. Optionally, a water pump 121 is installed at the bottom of the water tank 120 to ensure the pumping effect of the water pump 121, and the water pump 121 is electrically connected to the power terminal 122 located on the top of the support member 124 via a water pump cable.

[0064] Furthermore, in order to enable the water pump 121 located at the bottom of the water tank 120 to communicate with the evaporation bracket 110 located at the top of the water tank 120, the humidifier 100 also includes a water pipe 125, one end of which is connected to the outlet of the water pump 121, and the other end is connected to the air inlet channel 112.

[0065] In some specific embodiments, in order to make the air cooler easier to carry and transport, the evaporation bracket 110 can enter the water tank 120 through the opening 123, so that when needed, the evaporation bracket 110 and the wet curtain 111 in the evaporation channel can be stored together in the water tank 120, so that the humidifying component 100 has only the volume of the water tank 120, thereby making it convenient for users to disassemble and transport the air cooler.

[0066] Since both the evaporation bracket 110 and the opening 123 are located at the top of the water tank 120, excess water from the wet curtain 111 inside the evaporation bracket 110 can automatically flow back into the water tank 120 through the opening 123. To prevent the evaporation bracket 110 from falling into the water tank 120 when needed, the humidifier 100 also includes a limiting member 130 installed on the water tank 120. Each limiting member 130 includes a first state and a second state. When all limiting members 130 are in the first state, the limiting member 130 blocks the opening 123 to prevent the evaporation bracket 110 from entering the water tank 120. When all limiting members 130 are in the first state, the multiple limiting members 130 can also support the evaporation.

[0067] When all the limiting members 130 are in the second state, the limiting members 130 avoid the opening 123, and the evaporation bracket 110 can enter the interior of the water tank 120 through the opening 123. At this time, the evaporation bracket 110 can be stored inside the water tank 120.

[0068] It should be noted that, as can be seen from the above, in some other embodiments, the evaporation bracket 110 can also be installed on the side of the water tank 120. However, in this embodiment, it is not necessary to set the limiting member 130. The evaporation bracket 110 can simply be removed from the side of the water tank 120 and inserted into the water tank 120 through the opening 123 at the top of the water tank 120.

[0069] Specifically, in some embodiments, see [link to relevant documentation]. Figure 5 The limiting member 130 includes a fixed part 131 and an elastic part 132 connected to each other. The fixed part 131 is fixedly installed on the water tank 120. When the limiting member 130 is in the first state, the elastic part 132 abuts against the evaporator bracket 110 and supports the evaporator bracket 110. At this time, the evaporator bracket 110 can be supported by the multiple elastic parts 132 of the multiple limiting members 130 without being subjected to external force, so that the evaporator bracket 110 can be kept fixed in the opening 123.

[0070] When the limiting member 130 is in the second state, the elastic part 132 elastically deforms in the direction of avoiding the evaporation bracket 110. At this time, the evaporation bracket 110 is subjected to external force. For example, if the user presses down on the evaporation bracket 110, the evaporation bracket 110 moves downward along the elastic part. The limiting member 130 can no longer support the evaporation bracket 110 and deforms to avoid the evaporation bracket 110, so that the evaporation bracket 110 can enter the water tank 120 through the opening 123 and complete the storage of the evaporation bracket 110.

[0071] Furthermore, in order to enable the elastic part 132 to elastically deform in the direction of avoiding the evaporation support 110, each elastic part 132 is provided with an elastic inclined surface 133 and an elastic plane 134 that are continuous with each other. The elastic inclined surface 133 is inclined relative to the plane where the opening 123 is located, and the elastic plane 134 is parallel to the plane where the opening 123 is located.

[0072] The evaporator support 110 is also provided with multiple lugs 240 corresponding to multiple limiting members 130. Each lug 240 has a continuous supporting plane 241 and a supporting inclined plane 242. When the limiting member 130 is in the first state, the supporting plane 241 of each lug 240 is parallel to and abuts against the elastic plane 134 of the corresponding limiting member 130, and the supporting inclined plane 242 of the lug 240 intersects with and abuts against the elastic plane 134 of the corresponding limiting member 130. At this time, the evaporator support 110 can be supported by the multiple limiting members 130 through the mutual abutment between the supporting plane 241 of each lug 240 and the elastic plane 134 of the corresponding limiting member 130.

[0073] When it is necessary to store the evaporator bracket 110, the evaporator bracket 110 can be squeezed downwards so that the support slope 242 of the lug 240 presses down against the elastic slope 133 of the corresponding limiting member 130, so that the elastic slope 133 moves away from the support slope 242, that is, the elastic part 132 moves away from the evaporator bracket 110, and the support plane 241 and the elastic plane 134 are also misaligned. The support plane 241 can continue to move downwards along the elastic slope 133 until the evaporator bracket 110 is completely inside the water tank 120.

[0074] Specifically Figure 4 In this embodiment, multiple support members 124 are arranged in a rectangular array, and the multiple support members 124 and the inner wall of the water tank 120 form a receiving space for accommodating the evaporation bracket 110. Limiting members 130 are provided on the support members 124 located at the four corners of the rectangle, and each limiting member 130 is located on the side of the support member 124 facing the receiving space. When the evaporation bracket 110 is lifted upward from the receiving space, the elastic part 132 of the limiting member 130 restores its deformation to support the evaporation bracket 110. When it is necessary to store the evaporation bracket 110, the evaporation bracket 110 can be squeezed downward, causing the elastic part 132 of the limiting member 130 to deform, and the evaporation bracket 110 falls into the receiving space, thus completing the storage of the evaporation bracket 110.

[0075] It should be noted that in other embodiments, the limiting member 130 can also be telescopically mounted on the water tank 120. When the limiting member 130 extends out of the water tank 120, the limiting member 130 is in the first state, and the evaporation bracket 110 can be supported by multiple limiting members 130. When the limiting member 130 retracts into the water tank 120, the limiting member 130 is in the second state, and the evaporation bracket 110 can be stored inside the water tank 120.

[0076] In some embodiments of this application, see [reference] Figure 6 and Figure 10 The evaporator bracket 110 surrounds and forms a receiving cavity 113, and has an installation port 114 that communicates with the receiving cavity 113. The fan body 200 can enter the receiving cavity 113 through the installation port 114, so that the installation of the fan body 200 is fixed and limited by the evaporator bracket 110.

[0077] The air inlet 210 of the fan body 200 is located inside the accommodating cavity 113, and the air inlet channel 112 and the wet curtain 111 surround the accommodating cavity 113. Thus, the air drawn by the fan body 200 through the air inlet 210 can pass through the air inlet channel 112 and the wet curtain 111 inside the air inlet channel 112, regardless of which direction it enters the air inlet 210, thereby improving the cooling and humidification effect of the air.

[0078] Furthermore, to prevent the airflow from the fan body 200 from being affected by the evaporator bracket 110, the air outlet 220 of the fan body 200 faces the mounting port 114, so that the air discharged from the air outlet 220 can blow towards the user through the mounting port 114. Alternatively, the air outlet 220 can be placed directly outside the receiving cavity 113, which also prevents the air discharged from the air outlet 220 from being affected by the evaporator bracket 110.

[0079] Specifically Figure 2 In one embodiment, the evaporation bracket 110 includes a first grille 140 surrounding the cavity 113 and a second grille 141 spaced apart from the first grille 140. An air inlet channel 112 is formed between the first grille 140 and the second grille 141. A wet curtain 111 is also disposed between the first grille 140 and the second grille 141. In order to improve the air intake effect of the fan body 200, grille-shaped air inlets 210 are provided on the side and the rear of the fan body 200, and an air outlet 220 is provided at the head of the fan body 200. A fan blade 250 is disposed between the head and the rear of the fan body 200, and a drive member 251 for driving the fan blade 250 is provided.

[0080] Thus, when the fan body 200 is installed in the accommodating cavity 113, the air inlet 210 abuts against the first grille 140, and the fan body 200 can draw air through the tail and side, and the drawn air can pass through the wet curtain 111 between the first grille 140 and the second grille 141 to achieve the effect of cooling and humidifying the air.

[0081] In some embodiments, in order to keep the wet curtain 111 always in a moist state, a water tank 115 is provided on the top of the evaporation bracket 110, and a water inlet 116 is connected to the water tank 115. The water inlet 116 is connected to the water outlet of the water pump 121, and the water pump 121 draws water from the water tank 120 and flows into the water tank 115.

[0082] The evaporation bracket 110 is also equipped with multiple drain outlets 119. Each drain outlet 119 is connected to the water tank 115 and the air inlet channel 112. The water flowing into the water tank 115 through the water inlet 116 will pass through multiple drain outlets 119 and flow into different positions of the wet curtain 111, thereby maintaining the overall wetting effect of the wet curtain 111.

[0083] Specifically Figure 6 In this embodiment, the water inlet 116 is connected to the water pump 121 via a water pipe 125. Since the water pipe 125 is flexible, it will not fall off even when the evaporation bracket 110 is retracted into the water tank 120, thus ensuring the reliability of the connection between the water pump 121 and the water inlet 116.

[0084] In some embodiments, see Figure 7 In order to install the wet curtain 111 onto the evaporation bracket 110, the bottom of the evaporation bracket 110 is provided with a fixing port 117 that communicates with the air inlet channel 112. The wet curtain 111 can enter the air inlet channel 112 through the fixing port 117. At the same time, the fixing port 117 can also be used for the wet curtain 111 to drain excess water into the water inlet tank 120.

[0085] To prevent the wet curtain 111 from falling off the evaporator bracket 110, the bottom of the evaporator bracket 110 is provided with multiple baffles 118, all of which are located inside the fixing port 117 to prevent the wet curtain 111 from passing through the fixing port 117, thereby fixing the wet curtain 111 inside the air inlet channel 112.

[0086] The aforementioned air cooler has at least the following advantages:

[0087] When users need cooling or humidification, the fan body 200 can be mounted on the humidifier 100, connecting the air inlet 210 of the fan body 200 to the air inlet channel 112 equipped with the evaporative cooling pad 111. The air exhausted from the fan body 200 is then humidified and cooled by the evaporative cooling pad 111, thus achieving the cooling and humidifying effects of the evaporative cooler. When users only need airflow or need to leave the working area of ​​the evaporative cooler, the fan body 200 can be detached from the humidifier 100 and used as a regular fan. Because the fan body 200 is detached from the humidifier 100, its smaller size makes it easier to carry. Thus, even if the operator leaves the working area of ​​the evaporative cooler, they can still use the fan body 200 for ventilation, greatly improving the efficiency of the evaporative cooler.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
