Description

Technical Field

[0001] The utility model relates to the technical field of evaporation, and more particularly to a small evaporative air cooler. Background Art

[0002] A small desktop evaporative cooler. The atomizer inside the cooler breaks down the water stored in the water tank into fine water droplets or water mist, increasing the natural evaporation rate of the water. When these naturally evaporated liquids are converted into a gaseous state, they absorb heat from the surrounding air, causing the ambient temperature to drop. At the same time, the atomized liquid, under the action of the air-cooling component, accelerates air flow, further increasing the evaporation rate, increasing the temperature drop of the surrounding air, and also playing a certain humidification role.

[0003] In existing evaporative coolers, the atomizer decomposes the water in the water tank into water mist, which is then blown out along with the airflow generated by the air-cooling component. During this process, the atomized liquid is intercepted due to structural obstruction, and the blowing rate is reduced. The atomized liquid that stagnates somewhere comes into contact with the air and structure, causing some of the water mist to condense and accumulate into water droplets, forming condensed water.

[0004] The presence of condensed water can have a variety of negative effects on the use of evaporative coolers, such as:

[0005] (1) Failure to drain condensate in time may cause the internal environment of the evaporative cooler to be too humid, which is conducive to the growth of mold and microorganisms, shortening the service life of the evaporative cooler and posing a threat to the health of users;

[0006] (2) If condensed water continues to accumulate, it can easily cause the internal components of the evaporative cooler to become damp, which in turn affects the safety and stability of the circuit and may even cause problems such as short circuits.

[0007] (3) The continuous accumulation of condensed water may also corrode the metal parts inside the evaporative cooler, accelerate their corrosion, and shorten the service life of the air conditioning fan.

[0008] (4) The continuous accumulation of condensed water will cause overflow, which will damage the surface where the evaporative cooler is placed, such as causing wooden furniture to become damp and deformed, or destroying the integrity of the floor.

[0009] Therefore, existing evaporative coolers are equipped with a water collection tank or other structure at the bottom to collect condensed water. However, this requires customers to clean the condensed water inside the water collection tank promptly during use to prevent it from overflowing. Furthermore, the water collection tank only mitigates the problems caused by the continuous accumulation of condensed water, but it cannot completely solve the problem of condensed water causing moisture inside the evaporative cooler. For example, the water collection tank cannot be completely sealed and can only reduce the amount of moisture inside the evaporative cooler. Subsequent natural evaporation will still cause moisture inside the evaporative cooler, which in turn poses safety issues for electrical components, corrosion of metal parts, and the growth of mold and microorganisms. Summary of the Invention

[0010] In order to overcome the shortcomings of existing coolers in the prior art due to the accumulation of atomized liquid, the utility model provides a small evaporative air cooler, which adjusts the position of the atomizing port and the spraying direction so that the atomized liquid is sprayed from the atomizing port directly into the air supply path of the air-cooling component and the outside of the cooler, avoiding the atomized liquid from touching any structure of the cooler and accumulating.

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] A small evaporative air cooler, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a housing assembly 100 and an atomizing assembly and an air cooling assembly 200 built into the housing assembly 100.

[0046] The front of the housing is provided with an electrical component 400 and a plurality of buttons. The electrical component 400 is electrically connected to the plurality of buttons, the air cooling component 200, and the atomizing component.

[0047] The atomizing assembly includes an atomizing core and a water tank 300. The water tank 300 is arranged above the air cooling assembly 200.

[0048] After being sprayed out from the mist outlet 301 , the atomized liquid directly enters the air supply path of the air-cooling assembly 200 , and the atomized liquid is sprayed out from the mist outlet 301 to the outside of the housing assembly 100 .

[0049] The water tank 300 is arranged above the air-cooling component 200, so that the atomized liquid can fall directly under the action of the atomizing core and the driving force of gravity. It directly enters the air supply path of the air-cooling component 200 without passing through other paths, and is directly sent out by the wind blown out by the air-cooling component 200. In addition, the movement path of the atomized liquid does not include any part of the shell component 100. The atomized liquid is directly transported to the outside of the shell component 100. Therefore, the atomized liquid will not accumulate on the shell component 100 to form water droplets, nor will it flow downstream along the shell component 100. Therefore, the bottom of the cooler does not need a water tank 300 to hold the liquid, and the utilization rate of the atomized liquid can also be improved to ensure that all the liquid can be blown out for cooling.

[0050] The shell assembly 100 includes a front shell 101, a rear shell 102, a grid bar 104 and a top cover 103. The front shell 101 and the rear shell 102 are snap-fitted together. The front shell 101 and the rear shell 102 are snap-fitted together with the outer wall of the water tank 300 respectively. The front shell 101 is snap-fitted together with the grid bar 104, and the top cover 103 is snap-fitted together with the top surface of the water tank 300.

[0051] The front shell 101 and the rear shell 102 are provided with a plurality of connecting posts and connecting slots correspondingly. The connecting posts are inserted into the connecting slots and fixed, so that the front shell 101 and the rear shell 102 are buckled and connected.

[0052] A plurality of raised connecting strips are provided at the connection between the front shell 101, the rear shell 102 and the outer wall of the water tank 300, and a plurality of connecting grooves corresponding to the positions of the connecting strips are provided at the bottom of the outer wall of the water tank 300. The connecting strips are embedded in the connecting grooves, so that the front shell 101, the rear shell 102 and the outer wall of the water tank 300 are snap-fitted and connected.

[0053] One end of the top cover 103 is hinged to one end of the water tank 300 , and the other end of the top cover 103 and the other end of the water tank 300 are in a movable buckle connection structure.

[0054] The grid bar 104 includes a square frame 1043, a horizontal bar 1041 and a vertical bar 1042. The square frame 1043 is provided with a plurality of holes or slots. The ends of the horizontal bar 1041 and the vertical bar 1042 are respectively inserted into the holes or slots, so that the horizontal bar 1041 and the vertical bar 1042 are cross-arranged front and back to form a grid structure.

[0055] The housing assembly 100 is generally a die-cast or injection-molded component. The housing assembly 100 as a whole is a hexahedral structure with rounded or curved edges and corners, so as to protect the internal structure and the product molding.

[0056] The front housing 101, viewed from the front, is a frame structure with a quadrilateral hole. A grid bar 104 is disposed within the semi-enclosed area of ​​the front housing 101. Multiple horizontal positioning ridges are evenly distributed on the inner wall of the front housing 101. When the grid bar 104 is placed within the front housing 101, the horizontal bars 1041 and vertical bars 1042 of the grid bar 104 are arranged side by side and then aligned front to back to form a grid-like structure with equal squares. This allows each horizontal bar 1041 and vertical bar 1042 to be accurately inserted into the frame 1043 and aligned with each positioning ridge, which acts as a limiter.

[0057] Frame 1043 includes a first sheet-like body serving as the front structure of the housing assembly and a second sheet-like body composed of multiple sheet-like structures for snapping frame 1043 into the front housing. The first and second sheets can be integrally formed, or a latch-and-slot structure can be provided between the two structures, with assembly completed through a connection similar to the latch-and-slot structure. The first sheet-like body is provided with multiple insertion holes, and the ends of the horizontal bars 1041 are shaped like needles. The needles are inserted into the insertion holes and connected to the nut-like structure, thereby securing the horizontal bars 1041 to the first sheet-like body. The second sheet-like body is integrally formed with the vertical bars 1042, or the second sheet-like body is provided with slots, so that the vertical bars 1042 connect to the slots, thereby securing the vertical bars 1042 to the second sheet-like body.

[0058] The inner wall surface of the front housing 101 is provided with a stepped mounting surface or a striped mounting surface, and the shape of the stepped mounting surface or the striped mounting surface corresponds to the shape of the wall surface of the frame 1043, so that the frame 1043 and the front housing 101 are assembled and connected to each other. The inner wall surface of the front housing 101 is provided with a concave and convex striped structure or a stepped mounting surface, and the outer surface of the corresponding frame 1043 is also provided with a striped structure or a stepped mounting surface of a matching shape. The size of the frame 1043 is slightly smaller than or flush with the quadrilateral hole surface of the front housing 101, so that the frame 1043 can move along the striped structure or the stepped mounting surface of the front housing 101 in the direction of the front housing 101, thereby allowing the frame 1043 to be inserted into the interior of the front housing 101, so that the front housing 101 and the frame 1043 are connected.

[0059] The rear shell 102 is provided with strip-shaped window panes at positions corresponding to the quadrilateral holes of the front shell 101. These window panes are radially arranged, with a solid structure at the center. Several hollow cylindrical sockets are provided in the solid structure at the center of the inner wall of the rear shell 102 for fixing, and each cylindrical socket is provided with a raised arc-shaped stop. The cylindrical sockets are aligned with the fixing screw holes around the motor 202 of the air-cooling assembly 200 and connected via screws. At this time, the frustum of the base of the motor 202 fits neatly into the space surrounded by the arc-shaped stop, so that the motor 202 is fixed in the center of the rear shell 102 and aligned with the front grille 104.

[0060] A connecting groove is provided at or near the edge of the front shell 101. This groove is designed to add a sheet-like structure to the shell structure, forming a connecting groove between the two structures. Correspondingly, a connecting column is provided on the rear shell 102. The connecting column is a protruding, solid cylindrical structure. Furthermore, a circular protrusion is provided on the side of the front shell 101, extending to the exterior of the front shell 101. At a corresponding position, a concave recess is provided on the rear shell 102. The protrusion is inserted into the recess, allowing the front shell 101 and rear shell 102 to engage.

[0061] The top cover 103 serves as the top closure of the housing structure and also as the closure for the water tank 300. One end of the top cover 103 is hinged to one end of the water tank 300, and the other end of the top cover 103 is connected to the other end of the water tank 300 in a movable, snap-fitting manner. By pulling a snap plate provided at one end of the top cover 103, the other end of the top cover 103 is movable, thereby exposing the interior of the water tank 300 for conveniently containing liquid for atomization.

[0062] Looking at the cooler from the outside, the surface is a shell-like structure formed by the front shell 101 and the rear shell 102 being fastened together. The front side is a lattice structure unique to the grid bars 104, and the back side is radial window pane slots. The shell-like structure formed by the front shell 101 and the rear shell 102 faces the outer wall of the water tank 300 upwards, and the top is the top cover 103.

[0063] In order to achieve both aesthetics and avoid accumulation of atomized liquid, the surface of the shell assembly 100 is configured to minimize structural settings, making the surface of the shell assembly 100 as smooth as possible. At the same time, the spray direction of the mist outlet 301 is toward the outside of the cooler, and no part of the shell assembly 100 is located in the spray direction. Taking the above conditions into consideration, the present invention sets a grid bar 104 recessed in the front shell 101. The grid bar 104 is set in the quadrilateral hole of the front shell 101, and a recessed space is formed by the square frame 1043. The depth of the recess is sufficient to meet the requirements of the setting of the mist outlet 301, so that the mist outlet 301 is set at the top of the square frame 1043.

[0064] An extension tube 302 is provided at the end of the mist outlet 301 , and the extension tube 302 is inclined in a direction away from the cooler.

[0065] An extension tube 302 is provided at the end of the mist outlet 301, and the extension tube 302 allows the atomized liquid that has just been sprayed out of the mist outlet 301 to move in a concentrated manner for a short distance. In general, the length of the extension tube 302 is very short, and the atomized liquid has just been sprayed out of the mist outlet 301, and its own power is relatively sufficient, so the amount accumulated on the inner wall of the extension tube 302 is small, and no water droplets will be formed, so the extension tube 302 can play a short-distance directional guiding role. Through the guidance of the extension tube 302, it is sufficient to allow the atomized liquid to enter the interior of the air-cooled path, rather than the edge position, so that the atomized liquid is blown by the wind with great force, so that the atomized liquid can be directly affected by the wind and move quickly to the outside of the cooler, so that the atomized liquid can directly play a cooling role, rather than accumulating around the shell assembly 100.

[0066] The optimized design ensures that the atomized liquid sprayed from the mist outlet 301 can accurately and directly enter the air supply path and touch the shell assembly 100 or other components of the cooler. The extension tube 302 is tilted toward the outside of the cooler so that the outlet of the extension tube 302 falls toward the outside of the cooler. In this way, the atomized liquid sprayed from the extension tube 302 will not accumulate to form water droplets.

[0067] The extension tube 302 passes through the guide opening provided in the guide housing 303, allowing the end of the extension tube 302 to extend outside the housing assembly 100. The guide housing 303 is a shell-like structure provided outside the extension tube 302. The guide housing 303 creates a space for the extension tube 302 within the housing assembly 100 and serves to fix the relative position of the extension tube 302 and the housing assembly 100. The extension tube 302 passes through the guide opening (which is a long hole-like structure) provided in the guide housing 303 and is guided by the guide housing 303 so that the end of the extension tube 302 extends outside the housing assembly 100. In addition, the provision of the guide housing 303 regularizes the assembly structure of the housing assembly 100, such as the front housing 202 and the frame of the grid bar 104, making it easier to process. If only the extension tube 302 were provided, the structural complexity of the assembly between the housing assembly 100 and the extension tube 302 would increase, making assembly relatively troublesome. The guide shell 303 is fixed to the inside of the shell assembly 100 with screws, and the stability of the extension tube 302, shell assembly 100 and other structures is improved. In addition, a shielding surface 3031 is provided at one end of the guide shell 303 close to the air-cooling assembly 200. The inclination angle of the shielding surface 3031 is the same as that of the extension tube 302, and both face away from the air-cooling assembly 200 and toward the outside of the cooler. The atomized liquid that is transported along the extension tube 302 and has a dispersing force at the moment of being ejected from the port can be blocked and then rebound to move outward, so as to smoothly enter the air supply path of the air-cooling self-test and be blown out outward, thereby preventing the atomized liquid from being sprayed into the interior of the air-cooling assembly 200 and eliminating the negative impact of the atomized liquid on the air-cooling assembly 200 and the interior of the cooler.

[0068] In this embodiment, a partition structure is provided inside the extension tube 302 , and the cross section of the extension tube 302 is two concentric circles with a horizontal line between the two concentric circles, so that a plurality of annular sectors are evenly formed between the two concentric circles.

[0069] In this embodiment, the extension tube 302 is an extension structure of the water tank 300, and the extension tube 302 and the water tank 300 are integrally formed, while the guide housing 303 is an independently made shell-like structure. In other embodiments, the extension tube 302, the guide housing 303, etc. are all independent structures, the extension tube 302 is positioned at the mist outlet 301 and is restricted by the external guide housing 303, and the guide housing 303 is restricted by the assembly structure and screw connection of the housing assembly 100, so that the position of the extension tube 302 and the guide housing 303 is stable. In another embodiment, the extension tube 302 and the guide housing 303 are both extension structures of the water tank 300, and the extension tube 302, the guide housing 303 and the water tank 300 are integrally formed.

[0070] On the front of the shell assembly 100, the mist outlet 301 is set at the top position of the space between the front shell 101 and the grid bar 104, so that the atomized liquid sprayed from the mist outlet 301 will not touch any components of the shell assembly 100 and directly enter the air supply path of the air-cooling assembly 200. The mist outlet 301 is surrounded by a multi-layer stepped arc-shaped concave structure, and an extension tube 302 and related structures that cooperate with the arc-shaped concave structure are set on the outside. A concave-convex structure that cooperates with the arc-shaped concave structure is set around the extension tube 302, and it is buckled around the mist outlet 301 so that it can be fixed with a fixing structure (such as a screw, or a combined mounting structure of a key and a socket).

[0071] The angle between the air supply path of the air cooling component 200 and the spraying direction of the atomizing port of the atomizing component is less than or equal to 90°.

[0072] After the atomized liquid leaves the atomizing port, it needs to directly enter the air supply path to avoid contact with other structures and prevent the atomized liquid from accumulating. If the atomized liquid avoids contact with other structures alone to prevent accumulation, then the atomizing port is directly aligned with the outside of the cooler and directly sprays the atomized liquid into the environment where the cooler is located. However, such an effect is similar to a humidifier and has no effect on the strengthening of the air-cooling effect. Therefore, it is necessary to at least make most of the atomized liquid enter the air supply path of the air-cooling component 200, and the spraying direction of the atomized liquid needs to be downward. On the other hand, based on the demand for making full use of gravity to strengthen the atomization effect, the water tank 300 is arranged above the air-cooling component 200. Therefore, in order to make the atomized liquid enter the air supply path of the air-cooling component 200, the spraying direction of the mist outlet 301 is downward, and the air supply path of the air-cooling component 200 is the front direction of the product, which is horizontally outward. Therefore, in order to prevent the atomized liquid from being sprayed into the cooler interior in reverse, the angle between the air supply path of the air-cooling component 200 and the spraying direction of the atomizing port of the atomizing component is less than or equal to 90 °.

[0073] The air cooling assembly 200 includes a motor 202 and a rotating fan 201. The rear shell 102 of the housing assembly 100 is provided with a fixing groove, and the motor 202 is embedded in the fixing groove. The output shaft of the motor 202 is assembled and connected to the rotating fan 201, so that the rotating fan 201 rotates along with the output shaft of the motor 202.

[0074] The motor 202 has a short circular structure with an output shaft in the center and multiple fixing screw holes around it. The motor 202 is connected to the cylindrical socket in the center of the rear shell 102 through the fixing screw holes by screws, so that the motor 202 is fixed on the rear shell 102.

[0075] The output shaft at the center of the motor 202 is connected to the center of the rotary fan 201. When the motor 202 is output, the output shaft rotates, driving the rotary fan 201 to rotate, thereby completing the air cooling effect.

[0076] A wire trough 203 is provided between the air cooling assembly 200 and the electrical assembly 400 . The wire trough 203 forms a closed space along the inner wall of the housing assembly 100 .

[0077] Starting from the end of the lead wires of the motor 202 of the air-cooling assembly 200, a hard material is used, such as the same material as the shell assembly 100, plastic, wood, etc., among which the most preferably used is a material with poor insulation or conductivity, to form a three-sided closed trough structure to form a wire trough 203, so that the lead wires of the motor 202 are laid along the lower surface of the water tank 300 and directly connected to the electrical assembly 400 set above the grid bar 104. This arrangement prevents the wires of the internal electrical assembly 400 from being exposed, improving the aesthetics of the product, and can prevent the atomized liquid from moving into the air-cooling assembly 200 (i.e., inside the cooler) due to unexpected factors, preventing its impact on the electrical assembly 400, such as negative conditions such as short circuits.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
