[0080] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0081] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0082] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints.

[0085] Figure 1 A spray fan 100 is shown, which blows out wind with water mist through blowing and spraying functions, and can cool and humidify a preset place. The spray fan 100 can be used in outdoor places, such as basketball courts, parks, playgrounds, etc., and the spray fan 100 can also be used in indoor places, such as shopping malls, factories, warehouses, etc.

[0086] like Figure 1 and Figure 2As shown, the spray fan 100 includes a fan assembly 11, a body 12, a nozzle 13 and a water injection port 14. The body 12 forms a frame 120 for supporting the fan assembly 11, and the body 12 includes a first shell 121a and a second shell 122a. The first shell 121a is formed with a first accommodating chamber 121b for accommodating water, and the second shell 122a is formed with a second accommodating chamber 122b. The water injection port 14 is used to inject water into the first accommodating chamber 121b, and a sealing assembly 141 matching the water injection port 14 is provided, so that when the water injection port 14 is completed, the water injection port 14 is closed by the sealing assembly 141.

[0087] In order to illustrate the technical solution of this application, the following is also defined: Figure 1 and Figure 2 The front, back, left, right, top and bottom sides are shown. Figure 1 and Figure 2 As shown, the fuselage 12 is a cubic structure. In some embodiments, in the vertical direction, the length L of the fuselage 12 is less than or equal to 600 mm; in the left-right direction, the width W of the fuselage 12 is less than or equal to 400 mm; in the front-back direction, the thickness T of the fuselage 12 is less than or equal to 200 mm. By setting the fuselage 12 as a regular-shaped structure, the spray fan 100 is easier to be stored when stored.

[0088] like Figure 3 As shown, the fan assembly 11 includes a fan blade 111 and a first motor 112 for driving the fan blade 111 to rotate, and the first motor 112 is used to drive the fan blade 111 to rotate around the axis of the first motor 112. The first motor 112 is sealed by a waterproof material to prevent water mist from entering the first motor 112 under the influence of the environment, etc. For example, the waterproof material can be a plastic film, etc., and the first motor 112 is sealed by the plastic film through a process such as hot air.

[0089] The nozzle 13 is used to spray water mist, and the nozzle 13 is arranged on the fan assembly 11, or on the fuselage 12. When the spray fan 100 is started, the water mist is sprayed from the nozzle 13 to the external environment, and the fan blades 111 rotate to generate airflow to blow the water mist sprayed from the nozzle 13 into the air, thereby reducing the temperature of the air in the environment.

[0090] like Figure 4 As shown, the spray fan 100 further includes a pump assembly 15 , which is located in the second accommodating chamber 122 b . The pump assembly 15 is used to pump the water in the first accommodating chamber 121 b to the nozzle 13 .

[0091] like Figure 4As shown, the spray fan 100 also includes a water inlet pipe 151 and a water outlet pipe 152. One end of the water inlet pipe 151 is connected to the first accommodating chamber 121b, and the other end of the water inlet pipe 151 is connected to the pump assembly 15, so that the water inlet pipe 151 can obtain water from the first accommodating chamber 121b, and transmit the obtained water to the pump assembly 15, and the pump assembly 15 receives the water obtained from the first accommodating chamber 121b. One end of the water outlet pipe 152 is connected to the pump assembly 15, and the other end of the water outlet pipe 152 is connected to the nozzle 13, and the water is transmitted from the pump assembly 15 to the nozzle 13, so that the nozzle 13 can obtain water for spraying. Among them, the pump assembly 15 can be as shown in FIG. Figure 4 The water inlet pipe 151 and the water outlet pipe 152 can be arranged in the second accommodating cavity 122b in the horizontal direction as shown, and other arrangement methods can also be used, which is not limited in this application. Figure 4 The arrangement shown is connected to the pump assembly 15, and can also be connected to the pump assembly 15 according to other arrangements, which are not limited in this application.

[0092] like Figure 4 As shown, the spray fan 100 further includes a second motor 153 for driving the pump assembly 15 to operate. The second motor 153 is connected to the pump assembly 15. The second motor 153 is used to drive the pump assembly 15 to pump the water in the first accommodating chamber 121b to the nozzle 13, that is, the pump assembly 15 is driven by the second motor 153 so that the water inlet pipe 151 can obtain water from the first accommodating chamber 121b, and the obtained water is pumped to the nozzle 13 through the water outlet pipe 152. The operating power of the pump assembly 15 is less than or equal to 10W.

[0093] like Figure 5 As shown, the spray fan 100 also includes a battery assembly 16, which is disposed in the second accommodating chamber 122b, and includes a battery pack 161 and a battery compartment 162. Since the pump assembly 15 is also disposed in the second accommodating chamber 122b, in order to improve the safety of the spray fan 100, a partition 154 can be provided between the pump assembly 15 and the battery assembly 16, so that when the pump assembly 15 fails and leaks, the partition 154 can prevent the leaked water from flowing to the battery assembly 16, thereby ensuring the safety of the battery assembly 16.

[0094] Alternatively, in some embodiments, the second housing 122a or the first housing 121a is formed with an access port, and the battery pack 161 is detachably connected to the access port. When the battery pack 161 is installed to the access port, the battery pack 161 is at least partially exposed. In other words, when the battery pack 161 is installed to the access port, the battery pack 161 is located outside the first accommodation cavity and the second accommodation cavity, which makes it convenient for the user to observe the remaining power of the battery pack.

[0095] The battery pack 161 is used to supply power to the first motor 112 and the second motor 153, so that the first motor 112 drives the fan blade 111 to rotate, and the second motor 153 drives the pump assembly 15 to operate. Among them, the battery pack 161 is connected to the circuit board assembly 155, and the circuit board assembly 155 further supplies power to the first motor 112 and the second motor 153. The circuit board assembly 155 is arranged in the second accommodating cavity 122b. Optionally, the circuit board assembly 155 includes a circuit board and a circuit board box. The circuit board is installed in the circuit board box. When the circuit board is arranged in the circuit board box, sealant can also be injected into the circuit board box, so that the waterproof performance of the circuit board assembly 155 can be improved. Optionally, the circuit board assembly 155 can also include only a circuit board, which is not limited in this application.

[0096] In some embodiments, the battery pack 161 is detachably connected to the body 12, and the battery pack 161 is detachable from the battery compartment 162 in the second accommodating cavity 122b. When the battery pack 161 is installed in the second accommodating cavity 122b, the first accommodating cavity 121b is at least partially located on the upper side of the battery pack 161 in the up-down direction, so that the battery pack 161 is located at the lower part of the body 12, thereby improving the stability of the spray fan 100. When the battery pack 161 is not installed in the second accommodating cavity 122b and is removed from the spray fan 100, the battery pack 161 can also be used to power other electric tools.

[0097] In some embodiments, the battery pack 161 is inserted into the second receiving cavity 122b along the left-right direction. Figure 6 As shown, in order to make the thickness of the body 12 of the spray fan 100 thinner, when the battery pack 161 is installed in the second accommodating cavity 122b, the thickness of the battery pack 161 along the blade axis 1111 of the fan blade 111 is less than or equal to 90mm. For example, the thickness of the battery pack 161 can be 75mm or 85mm. That is, the thinnest surface of the battery pack 161 is opposite to the side of the body 12, so that the battery pack 161 is installed horizontally in the second accommodating cavity 122b. Therefore, the installation direction of the battery compartment 162 in the second accommodating cavity 122b matches that of the battery pack 161. Figure 5As shown, a first movable opening 122c is provided on the side of the second shell 122a, and the battery pack 161 is inserted into the second accommodating cavity 122b from left to right or from right to left by opening the first movable opening 122c. Among them, the opening area of ​​the first movable opening 122c is larger than the area of ​​the thinnest surface of the battery pack 161. Optionally, the number of battery packs 161 may be greater than or equal to one, and the nominal voltage of the battery pack 161 is greater than or equal to 6V and less than or equal to 56V. In some embodiments, the nominal voltage of the battery pack is equal to or equal to 3.6V and less than or equal to 36V. In some embodiments, the nominal voltage of the battery pack 161 is greater than or equal to 6V and less than or equal to 36V. In some embodiments, the nominal voltage of the battery pack is greater than or equal to 6V and less than or equal to 24V. The operating current of the battery pack 161 is greater than or equal to 0.5A and less than or equal to 5A. For example, when the nominal voltage of one battery pack is 4V, the number of battery packs 161 is 2 and the two battery packs are connected in series, the nominal voltage of the battery assembly 16 is 8V.

[0098] In some embodiments, Figure 7 As shown, a power display component 123 is also provided on the body 12 of the spray fan 100, and the power status of the battery pack 161 is displayed by the power display component 123. The power display component 123 can be provided on the second shell 122a, so that it is close to the battery pack 161, which is convenient for displaying the power status of the battery pack 161. Among them, the power display component 123 can be composed of multiple display windows. When the battery pack 161 is fully charged, the multiple display windows all remain in a long-lit state. When the battery pack 161 is half-charged, half of the multiple display windows are in a long-lit state, and the other half are in a long-dark state. In addition, the power display component 123 can also display the power status of the battery pack 161 in other ways, which is not limited in this application.

[0099] like Figure 7 As shown, the spray fan 100 further includes a water mist regulating assembly 17, which is disposed on the second housing 122a of the spray fan 100. For the convenience of user operation, the water mist regulating assembly 17 is disposed on the front side (front) of the spray fan 100, that is, on the front side (front) of the second housing 122a. The water mist regulating assembly 17 is connected to the pump assembly 15, and is used to control the amount of water that the pump assembly 15 pumps the water in the first accommodating chamber 121a to the nozzle 13. Optionally, the water mist regulating assembly 17 may be as follows: Figure 7The knob-type assembly shown controls the amount of water pumped to the nozzle 13 by the pump assembly 15 by rotating the knob. For example, when the water mist regulating assembly 17 rotates to the far left, the pump assembly 15 is in a non-working state, that is, the amount of water pumped to the nozzle 13 by the pump assembly 15 is 0.

When the angle adjustment component 19 is stored in the storage groove 193, the angle adjustment component 19 does not protrude from the outer surface of the body 12, so that the outer surface of the body 12 tends to be flat, thereby making the spray fan 100 easier to store. Figure 8 The hinged support leg shown may also be any other component form that can play a supporting role, and this application does not limit it.

[0102] In some embodiments, the volume (water storage capacity) of the first accommodating chamber 121b is less than or equal to 20L, for example, the volume of the first accommodating chamber 121b may be 3.5L.

[0108] like Fig.13 As shown, the nozzle 13 is arranged on the fuselage 12, specifically, on the front side of the first shell 121a, that is, the front side of the fuselage 12. Optionally, the nozzle 13 is detachable and can be removed from the first shell 121a when the nozzle 13 fails to function. Optionally, the nozzle 13 can also be retractable. A storage groove 131 matching the nozzle 13 can be provided on the first shell 121a, and when the nozzle 13 does not need to spray water mist, the nozzle 13 can be stored in the storage groove 131, and when the nozzle 13 is stored in the storage groove 131, the nozzle 13 does not protrude from the outer surface of the fuselage 12, so that the outer surface of the fuselage 12 remains flat, which is convenient for the storage of the spray fan 100. Optionally, the storage groove 131 can be arranged as follows Fig.13 The position shown in the figure may also be set at other positions on the front of the body 12 that can accommodate the nozzle 13, which is not limited in this application. Optionally, the position of the nozzle 13 may be as follows: Fig.13 The nozzle 13 is shown at the lowest position where the fan assembly 11 and the first shell 121a meet, that is, the lowest point where the fan assembly 11 rotates. The position of the nozzle 13 can also be any position where the fan assembly 11 and the first shell 121a meet, and this application does not limit it.

[0109] In some embodiments, the diameter of the blade 111 of the fan assembly 11 is greater than or equal to 5 inches and less than or equal to 20 inches, for example. The diameter of the blade 111 of the fan assembly 11 may be 6 inches, or 7 inches.

In some embodiments, the nozzle 13 is disposed on the fan assembly 11. Specifically, the nozzle 13 can be disposed on the front fan mesh 113, so that the nozzle 13 does not affect the normal operation of the fan assembly 11. Optionally, the nozzle 13 can be detachable. Optionally, the nozzle 13 can also be retractable. When the nozzle 13 is retractable, such as Fig.15 As shown, a nozzle receiving groove 132 matching the nozzle 13 is provided on the front fan mesh cover 113. When the nozzle 13 does not need to spray water mist, the nozzle 13 is received in the nozzle receiving groove 132. When the nozzle 13 is received in the receiving groove 132, the nozzle 13 will not protrude from the outer surface of the fuselage 12, so that the outer surface of the fuselage 12 remains flat, thereby making the spray fan 100 easier to receive. At the same time, when the spray fan 100 falls forward, the nozzle 13 can be received in the nozzle receiving groove 132, so that the nozzle 13 will not be damaged, thereby improving the service life of the nozzle 13. Optionally, the present application does not limit the position of the nozzle 13 on the front fan mesh cover 113, and the nozzle 13 can be located at any suitable working position on the front fan mesh cover 113.

The spray fan 100 in the present application uses the fuselage 12 as both a frame to support the fan assembly 11 and a water storage device for the spray fan 100, so that the spray fan 100 is more convenient to use. Even if the spray fan 100 is far away from the water source, the spray fan 100 can rely on the water stored in the fuselage 12 to spray. In addition, when the spray fan 100 needs to be added with water, the spray fan 100 can be directly moved to add water, without separating the spray fan from the water bucket and adding water to the water bucket as in the prior art. At the same time, when the spray fan needs to be moved, the spray fan 100 in the present application is also more convenient to move. In addition, since the fuselage 12 of the spray fan 100 in the present application is a cubic structure, the spray fan 100 can be neatly arranged when stored, which is convenient for storage.
