Fixing support, water storage tank, water supply structure and electric appliance

Abstract

The application relates to a fixing support, a water storage tank, a water supply structure and an electrical appliance. The fixing support is arranged in the water storage tank. One end of the water storage tank is provided with a main water tank. The fixing support comprises a support body provided with a fixing cavity for limiting a delivery pump, and a supporting piece arranged at one end of the support body. The supporting piece is used for supporting the main water tank to make the main water tank communicate with the water storage tank. When the main water tank is installed on one side of the water storage tank, the main water tank communicates with the water storage tank under the support of the supporting piece, and water in the main water tank can flow into the water storage tank along the supporting piece. When the main water tank is separated from the water storage tank, the main water tank is disconnected from the water storage tank without the support of the supporting piece, so that water leakage from the main water tank can be prevented. Moreover, since the supporting piece is integrated on the fixing support, the fixing support can also fix the delivery pump through the support body, the internal structure of the water storage tank is simplified, and the space occupation in the water storage tank is reduced.

Description

Technical Field

[0001] This application relates to the field of humidification equipment technology, and in particular to a fixed bracket, a water storage tank, a water supply structure, and electrical equipment. Background Technology

[0002] With the development of technology and the improvement of living standards, people's requirements for the comfort of their living environment are also gradually increasing. As an evaporative cooling device that falls between a fan and an air conditioner, evaporative air coolers are widely used in people's production and daily life, effectively improving their living and working environments. An evaporative air cooler typically includes a water tank, a delivery pump, an evaporation unit, and a fan. The delivery pump draws water from the tank and distributes it to the evaporation unit to form a water film. External airflow is drawn in at high speed by the fan, causing the water on the water film to rapidly evaporate from a liquid state to a gaseous state, absorbing heat from the airflow. The cool air is then delivered at high speed through the air vents, achieving the cooling function.

[0003] In existing evaporative air coolers, the water level in the tank decreases as water is consumed. The efficiency of the delivery pump is closely related to the water level. When the water level is high, the pump experiences greater pressure, resulting in more water being drawn to the evaporative cooling pad assembly, thus increasing the humidification efficiency. Conversely, when the water level is low, the pump experiences less pressure, leading to less water being drawn to the assembly and affecting its humidification efficiency. Conversely, if the water level is too high, water will overflow.

[0004] To address the aforementioned issues, some air coolers include a primary water tank and a secondary water tank stacked together. The secondary water tank is equipped with a delivery pump, allowing water from the primary water tank to flow into the secondary water tank in a controlled manner, thereby maintaining a stable water level in the secondary water tank. However, how to control the opening and closing of the outlet of the primary water tank has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] Therefore, it is necessary to provide a fixed bracket, a water storage tank, a water supply structure, and electrical equipment to address the issue of opening and closing the primary water tank.

[0006] A fixed support is disposed inside a water storage tank, one end of which is provided with a main water tank. The fixed support includes:

[0007] The main body of the support has a fixed cavity for limiting the delivery pump; and

[0008] A retaining member protrudes from one end of the support body and is used to abut against the main water tank so that the main water tank is connected to the storage tank.

[0009] In one embodiment, the fixing bracket further includes at least one limiting rib, each of the limiting ribs protruding from the cavity wall of the fixing cavity, and the limiting ribs are used to abut against the delivery pump.

[0010] In one embodiment, at least one of the limiting ribs is perpendicular to the surface of the delivery pump that contacts the limiting rib.

[0011] A water storage assembly includes a water storage tank and the aforementioned fixing bracket, wherein the fixing bracket is installed inside the water storage tank.

[0012] In one embodiment, the water storage assembly further includes a delivery pump housed within the water storage tank and at least partially confined within the fixed cavity of the fixed bracket.

[0013] In one embodiment, the delivery pump has a water outlet connector located outside the fixed cavity.

[0014] A water supply structure includes the aforementioned water storage tank, and the water supply structure further includes a main water tank located on one side of the water storage tank, the main water tank being connected to the water storage tank under the support of the supporting member.

[0015] In one embodiment, the main water tank is provided with a water outlet, and a control unit is installed at the water outlet. The control unit is capable of moving relative to the water outlet under the support of the abutment to open the water outlet.

[0016] An electrical appliance comprising the aforementioned water supply structure.

[0017] In one embodiment, the electrical device is a cooling fan.

[0018] When the main water tank is installed on one side of the storage tank, the main water tank is connected to the storage tank under the support of the retaining member, allowing water in the main water tank to flow into the storage tank along the retaining member. When the main water tank is detached from the storage tank, it loses the support of the retaining member and disconnects from the storage tank, thus preventing water leakage from the main water tank. Furthermore, since the retaining member is integrated into the fixed bracket, the fixed bracket can also secure the delivery pump through the bracket body, simplifying the internal structure of the storage tank and reducing the space occupied inside the storage tank.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. 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.

[0034] See Figure 1 and Figure 2 This application provides an electrical device with a water supply structure 20. The structure of the water supply structure 20 in this application will be described below using a fan 100 as an example. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electrical device may also be other devices equipped with the water supply structure 20, such as a humidifier, etc., which are not limited here.

[0035] The air cooler 100 includes a body and a fan head. The body can be placed on a load-bearing surface such as the ground, and the water supply structure 20 is located in the body. The fan head is installed on the top of the body and contains a fan wheel and a wet curtain assembly 40. The fan wheel is used to generate directional airflow, and the wet curtain assembly 40 is connected to the water supply structure 20 through pipes to humidify and cool the airflow passing through the fan wheel.

[0036] Please combine Figure 1 , Figure 3 and Figure 4 As shown, the water supply structure 20 includes a main water tank 21 and a water storage assembly 23. The bottom of the main water tank 21 has an outlet 21a for water discharge. The water storage assembly 23 is connected to the bottom of the main water tank 21 and includes a water storage tank 232 and a delivery pump 234 disposed within the water storage tank 232. The end of the water storage tank 232 facing the main water tank 21 is open to communicate with the outlet 21a. The delivery pump 234 is connected to the upper end of the evaporative cooling pad assembly 40 via a water inlet pipe, and the lower end of the evaporative cooling pad assembly 40 is connected to the water storage tank 232 via a drain pipe.

[0037] Thus, the user can first fill the main water tank 21 with water, and then install the main water tank 21 onto the storage tank 232. The water in the main water tank 21 flows into the storage tank 232 through the outlet 21a, and then is delivered to the water supply pipe by the delivery pump 234, thereby supplying water to the evaporative cooling pad assembly 40. The water flowing out of the evaporative cooling pad assembly 40 returns to the storage tank 232 through the drain pipe, thus realizing water recycling.

[0038] As described in the background section, when the main water tank 21 is installed above the storage tank 232, the outlet 21a needs to be opened to allow water from the main water tank 21 to flow into the storage tank 232. However, when the main water tank 21 is removed from the storage tank 232, the outlet 21a needs to be closed promptly to prevent water leakage from the main water tank 21.

[0039] To resolve the above issues, please refer to Figures 3 to 5 The water storage component 23 in this application also includes a fixed bracket 236, which includes a bracket body 2361 and a supporting member 2363. The bracket body 2361 has a fixed cavity 2361a for limiting the delivery pump 234, and the supporting member 2363 protrudes from one end of the bracket body 2361.

[0040] Thus, when the main water tank 21 is installed above the storage tank 232, the main water tank 21 opens under the support of the retaining member 2363, allowing water in the main water tank 21 to flow into the storage tank 232 along the retaining member 2363. When the main water tank 21 detaches from the storage tank 232, it loses the support of the retaining member 2363 and returns to a sealed state, thus preventing water leakage from the main water tank 21. Moreover, since the retaining member 2363 is integrated into the fixed bracket 236, the fixed bracket 236 can also fix the delivery pump 234 through the bracket body 2361, thereby simplifying the internal structure of the storage tank 232, reducing space occupation, and increasing the internal volume of the storage tank 232.

[0041] In some embodiments, the hollow tank structure of the water storage tank 232 includes a bottom wall and a side wall. The side wall extends from the edge of the bottom wall toward the side where the main water tank 21 is located, and the side wall surrounds the bottom wall in the circumferential direction to form a cavity with one end open.

[0042] The fixing bracket 236 can be fixedly installed in the water storage tank 232 by means of screw connection, snap-fit ​​connection, etc. It can be understood that the fixing method of the fixing bracket 236 is not limited and can be set as needed to meet different installation requirements.

[0043] The fixed bracket 236 includes a top wall 2361b and a side wall 2361c. The side wall 2361c extends from the edge of the top wall 2361b toward the bottom wall of the box until it abuts against the bottom wall of the box. The top wall 2361b and the side wall 2361c together define a fixed cavity 2361a. The side wall 2361c has a connecting groove that connects to the fixed cavity 2361a. Therefore, one end of the delivery pump 234 can extend into the fixed cavity 2361a through the connecting groove. The fixed bracket 236 covers one end of the delivery pump 234.

[0044] The abutment 2363 has a cylindrical structure. One end of the abutment 2363 is connected to the top wall 2361b of the support, and the other end of the abutment 2363 extends toward the outlet 21a of the main water tank 21 to enter the outlet 21a. The outer diameter of the abutment 2363 is smaller than the inner diameter of the outlet 21a. Therefore, water in the main water tank 21 can flow into the water storage tank 232 through the gap between the abutment 2363 and the outlet 21a. The abutment 2363 can also guide the water flow and reduce noise. It is understood that the shape and length of the abutment 2363 are not limited. In some other embodiments, the abutment 2363 may not extend into the outlet 21a.

[0045] In some embodiments, the fixed bracket 236 further includes at least one limiting rib 2365, which protrudes from the cavity wall of the fixed cavity 2361a and is used to support the delivery pump 234.

[0046] Thus, the delivery pump 234 is at least partially confined in the fixed cavity 2361a of the support body 2361 under the resistance of the limiting rib 2365. The limiting rib 2365 can not only limit the delivery pump 234, but also disperse and reduce the vibration generated by the delivery pump 234, reduce the resonance noise of the delivery pump 234, thereby reducing the overall operating noise and vibration of the cooling fan 100 equipped with it, reducing noise pollution, and improving the user experience.

[0047] Furthermore, the limiting ribs 2365 extend from the top wall 2361b of the support towards the bottom wall of the water tank 232, and at least one limiting rib 2365 is perpendicular to the surface of the delivery pump 234 that contacts it, thereby achieving a better vibration damping effect. It is understood that the number, shape, and arrangement of the limiting ribs 2365 are not limited and can be designed according to the shape of the delivery pump 234 and the water tank 232 to meet different vibration damping and limiting requirements.

[0048] In one specific embodiment, four limiting ribs 2365 are connected end-to-end to form a quadrilateral structure to abut against the upper surface of the delivery pump 234 facing the main water tank 21. Another portion of the limiting ribs 2365 are located around the aforementioned four limiting ribs 2365 to abut against the side surface of one end of the delivery pump 234. As a preferred embodiment, the abutting direction of the limiting ribs 2365 is perpendicular to the axis of the impeller in the delivery pump 234, thereby achieving a better vibration damping effect.

[0049] The delivery pump 234 includes a water outlet connector 2341 at one end for connecting to a water supply pipe, and the other end of the delivery pump 234 extends through a connecting groove into a fixed cavity 2361a, thereby being fixed to the water storage tank 232 by a fixed bracket 236. Thus, the water outlet connector 2341 is located outside the fixed cavity 2361a, so the arrangement of the fixed bracket 236 does not affect the arrangement of the water supply pipe connected to the water outlet connector 2341.

[0050] In some embodiments, a control unit 25 is installed at the outlet 21a of the main water tank 21. The control unit 25 can move relative to the outlet 21a under the support of the abutment 2363 of the fixed bracket 236 to open the outlet 21a.

[0051] Specifically, the control unit 25 includes a moving rod 252 and a seal 254. The moving rod 252 has a rod-shaped structure and extends into the main water tank 21 through the outlet 21a. The seal 254 is sleeved on the moving rod 252, and the outer diameter of the seal 254 is larger than the inner diameter of the outlet 21a, so that it can abut against the edge of the outlet 21a.

[0052] Thus, when the main water tank 21 and the storage tank 232 are separated, the sealing member 254 abuts against the edge of the outlet 21a to seal the outlet 21a. When the main water tank 21 and the storage tank 232 are connected, the sealing member 254 moves upward in the first direction under the push of the abutment member 2363, thereby forming a gap between the edges of the outlet 21a that connects to the outlet 21a, through which water in the main water tank 21 can flow out through the outlet 21a.

[0053] In some embodiments, the control unit 25 further includes a reset member 256, which can undergo recoverable deformation under external force to apply a force to the moving rod 252 to move it away from the main water tank 21. Specifically, in one embodiment, the reset member 256 is a compression spring sleeved on the moving rod 252, with one end of the reset member 256 limited to the main tank 21 and the other end limited to the end of the moving rod 252 away from the main water tank 21.

[0054] Thus, when the main water tank 21 and the storage tank 232 are separated, the moving rod 252 moves away from the main water tank 21 due to the gravity of the water and the thrust of the resetting member 256, and the sealing member 254 tightly abuts against the edge of the outlet 21a to close the outlet 21a. When the main water tank 21 and the storage tank 232 are connected, the resetting member 256 pushes the moving rod 252 to move towards the main water tank 21 against the gravity of the water and the thrust of the resetting member 256. The resetting member 256 switches from the initial state to the compressed state, and the sealing member 254 leaves the edge of the outlet 21a to open the outlet 21a, allowing water in the main water tank 21 to flow out through the outlet 21a.

[0055] In some embodiments, the bottom wall of the main water tank 21 protrudes outward to form a protruding outlet 21a, the lowest point of which is lower than the highest water level line of the water storage tank 232.

[0056] Thus, when the water level in the water storage tank 232 is high and the water level is higher than the lowest point of the outlet 21a, the outlet 21a is sealed by the water in the water storage tank 232. Under the action of atmospheric pressure, the water in the main water tank 21 automatically stops flowing into the water storage tank 232, thereby preventing the water in the water storage tank 232 from overflowing due to excessive water.

[0057] As water in the storage tank 232 is continuously transported to the wet curtain assembly 40 by the delivery pump 234, the water level in the storage tank 232 drops until it is lower than the lowest point of the outlet 21a. At this point, the outlet 21a is in an unsealed state, and the main water tank 21 is connected to the outside atmosphere. Therefore, the water in the main water tank 21 flows back into the storage tank 232 until the water level in the storage tank 232 is higher than the lowest point of the outlet 21a again.

[0058] In this way, the main water tank 21 achieves automatic water discharge through atmospheric pressure, thereby maintaining the water in the water storage tank 232 within a certain range, thus keeping the working state of the delivery pump 234 in the water storage tank 232 stable to ensure constant humidification efficiency, while preventing the water in the water storage tank 232 from overflowing.

[0059] The aforementioned fixed bracket 236, water storage tank 232, water supply structure 20, and electrical equipment integrate the functions of fixing the delivery pump 234 and opening the main water tank 21. It can also reduce vibration and noise of the delivery pump 234 and reduce noise of the water flowing from the main water tank 21 into the water storage tank 232. It also effectively simplifies the internal structure of the water storage tank 232, ensuring that the water storage tank 232 has sufficient volume without increasing the overall volume of the water storage tank 232, and further optimizes the appearance and user experience of the electrical equipment.

[0060] 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.

[0061] 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.
