Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of humidifying equipment, in particular to a water pump assembly, a water tank device and a humidifying equipment. BACKGROUND

[0002] A humidifying equipment such as a cooling fan achieves a cooling effect through physical evaporation. The water system of the humidifying equipment generally includes a water tank, a water pump and a wet curtain module. The water pump draws water in the water tank into a water distribution box of the wet curtain module, the water evenly falls from the water distribution box into the wet curtain, and forms a dense water film on the wet curtain. When air enters, the water film will take away part of the heat in the air, thereby achieving the effect of physical cooling.

[0003] However, the water pump is prone to sucking in scale impurities in the water during operation, which will inevitably cause the water pump to be blocked over a long period of time, affecting the work of the water pump. Especially in areas with hard water, users often encounter water pump blockage after using the humidifying equipment for a period of time, and the water pump after being blocked is prone to overload damage, which seriously affects the user experience. SUMMARY

[0004] Therefore, the present application provides a water pump assembly, a water tank device and a humidifying equipment to solve the problem of easy blockage of the water pump.

[0005] In a first aspect, the present application provides a water pump assembly, comprising:

[0006] a water pump;

[0007] a water pump support comprising a support body and a scale inhibition box fixedly arranged on the support body, the support body being provided with an installation space capable of accommodating the water pump, and the water pump being installed in the support body;

[0008] The scale inhibition box is located at the water inlet end of the water pump, the scale inhibition box has a scale inhibition cavity capable of accommodating a scale inhibitor, and the scale inhibition box is hollow.

[0009] Beneficial effects: By setting the scale inhibition box at the water inlet end of the water pump, placing the scale inhibitor in the scale inhibition cavity of the scale inhibition box, a good scale inhibition effect can be formed near the water inlet end of the water pump. When the water pump is working, the water flows through the scale inhibition box and reacts with the scale inhibitor in the scale inhibition cavity. The scale inhibitor can absorb trace substances in the water to adjust the water quality and prevent calcium and magnesium ions in the water from forming scale. The water purified by the scale inhibitor is then fed into the water pump, effectively preventing scale from clogging the water pump and facilitating use in areas with hard water. The scale inhibition box is hollow, which can connect the scale inhibition cavity, the external water source, and the water inlet end of the water pump. This allows the scale inhibitor to release active factors into the water to achieve scale inhibition and water purification, providing purified water to the water pump and effectively solving the problem of water pump clogging, improving the safety and reliability of the water pump operation. In addition, the scale inhibition box on the water pump bracket not only allows the water pump bracket to install the water pump, but also has the functions of scale inhibition and water purification, saving space, simplifying the number of parts, and expanding the functions of the water pump bracket.

DETAILED DESCRIPTION

[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0074] In the current humidification equipment, a water pump is an indispensable structure, and the water pump needs to work to transmit water to the corresponding position. However, the water pump structure and function used in the current humidification equipment on the market are relatively single, and often only a single water pump with only the function of pumping water. However, the water pump is easy to suck in scale impurities in the water during operation, which will inevitably cause blockage and affect the work of the water pump over a long period of time.

[0075] After analysis by the technical personnel, since the backflow water on the wet curtain of the waterway system of the humidification equipment also plays the purpose of cleaning the air, the backflow water contains the debris of the air blown to the wet curtain, and the debris remaining in the water pump is easy to cause the water pump to be blocked. In addition, the silt, algae and other debris in the water during water filling are also easy to block the water pump. Moreover, when the water quality is too hard, calcium and magnesium ions in the water form scale, and after multiple cycles, the scale is easy to block the water pump. After being blocked, the water pump is easy to cause overload damage. Moreover, the blocked waterway is difficult to clean, and users are also difficult to replace independently.

[0076] The embodiments of the present application will be described below in combination with Figures 1 to 17 , the embodiments of the present application.

[0077] According to an embodiment of the present application, in one aspect, as shown in Figures 1 to 7 、 Figure 11 、 Figures 15 to 17 A water pump assembly is provided, comprising a water pump 2 and a water pump support 4, the water pump support 4 comprising a support body and a scale inhibition box 3 fixedly arranged on the support body, the support body being provided with a mounting space capable of accommodating the water pump 2, and the water pump 2 being mounted in the support body; the scale inhibition box 3 is located at a water inlet end 21 of the water pump 2, the scale inhibition box 3 has a scale inhibition cavity capable of accommodating a scale inhibitor 31, and the scale inhibition box 3 is hollow.

[0078] The scale inhibition box 3 is arranged at the water inlet end 21 of the water pump 2, and the scale inhibitor 31 is placed in the scale inhibition cavity of the scale inhibition box 3, so that a good scale inhibition effect can be achieved near the water inlet end 21 of the water pump 2. When the water pump 2 is working, the water flows through the scale inhibition box 3 and reacts with the scale inhibitor 31 in the scale inhibition cavity. The scale inhibitor 31 can absorb trace substances in the water, adjust the water quality, prevent calcium and magnesium ions in the water from forming scale, and prevent the water pump 2 from being blocked by scale. The water source purified by the scale inhibitor 31 is then introduced into the water pump 2, thereby effectively preventing the water pump 2 from being blocked by scale and facilitating use in areas with hard water. The scale inhibition box 3 is hollow, which can connect the scale inhibition cavity, the external water source, and the water inlet end 21 of the water pump 2. The scale inhibitor 31 can release active factors into the water to achieve the effects of scale inhibition and water purification. The purified water source is provided to the water pump 2, effectively solving the problem of easy blockage of the water pump 2 and improving the operation safety and reliability of the water pump 2. In addition, the scale inhibition box 3 arranged on the water pump support 4 not only enables the water pump support 4 to mount the water pump 2, but also has the functions of scale inhibition and water purification. This design saves space, simplifies the number of components, and expands the functions of the water pump support 4. The one thing has multiple uses, and the structure is simplified.

[0079] In some embodiments, along the water inlet direction of the water pump 2, the two side walls of the scale inhibition box 3 are respectively provided with water permeable holes 34.

[0080] Through the design of the water permeable holes 34, the water flowing through the water permeable holes 34 can be inhibited and purified by the scale inhibitor 31. Specifically, when the water pump 2 is in the water inlet state, the water can pass through the scale inhibition box 3, be inhibited and purified by the scale inhibitor 31 in the scale inhibition box 3, and then be introduced into the water pump 2, thereby greatly reducing the risk of blockage of the water pump 2.

[0081] In some embodiments, the scale inhibitor 31 is in a granular form, and the diameter of the water permeable holes 34 is smaller than the outer diameter of the scale inhibitor 31. By setting the diameter of the water permeable holes 34 to be smaller than the outer diameter of the scale inhibitor 31, the scale inhibitor 31 can be effectively prevented from escaping from the scale inhibition box 3 through the water permeable holes 34.

[0082] In some embodiments, the scale inhibition box 3 comprises a scale inhibition box body 32 and a scale inhibition cover 33, the scale inhibition box body 32 is integrally formed on the bracket body, and the scale inhibition box body 32 is a box structure with one side open; the scale inhibition cover 33 is movably arranged at the box opening of the scale inhibition box body 32, and forms a scale inhibition cavity with the scale inhibition box body 32.

[0083] In the above embodiment, the scale inhibition box body 32 can accommodate the scale inhibitor 31, the scale inhibition box body 32 is integrally formed on the water pump bracket 4, which can enhance the stability of the scale inhibition box 3, and can make the scale inhibition box 3 closer to the water pump 2, and form a better scale inhibition effect near the water pump 2; the arrangement of the scale inhibition cover 33 facilitates the addition and removal of the scale inhibitor 31, facilitates the replacement of the scale inhibitor 31, and can also effectively prevent the scale inhibitor 31 from falling out of the box opening of the scale inhibition box body 32 to limit the scale inhibitor 31 in the scale inhibition cavity.

[0084] Preferably, the scale inhibition box body 32 is provided with an opening at the top, and the scale inhibition cover 33 is movably arranged at the top of the scale inhibition box body 32.

[0085] In some embodiments, water-permeable holes 34 are arranged on the scale inhibition box body 32 and the scale inhibition cover 33, which can facilitate the release of active factors of the scale inhibitor 31 into the water near the water inlet end 21 of the water pump 2 to achieve scale inhibition effect.

[0086] In some embodiments, one end of the scale inhibition cover 33 is movably connected to the scale inhibition box body 32, and the other end is clamped to the scale inhibition box body 32.

[0087] In the above embodiment, by designing one end of the scale inhibition cover 33 to be movably connected to the scale inhibition box body 32, the scale inhibition cover 33 can be conveniently opened and closed, and the scale inhibition cover 33 is effectively prevented from being separated from the scale inhibition box body 32. By designing the other end of the scale inhibition cover 33 to be clamped to the scale inhibition box body 32, the scale inhibition cover 33 and the scale inhibition box body 32 can be reliably connected without the need for additional connecting parts, and the opening and closing of the scale inhibition cover 33 is also facilitated.

[0088] In some embodiments, the scale inhibition box body 32 comprises a first side wall 321 and a second side wall 322 arranged opposite to each other, and the second side wall 322 is located between the first side wall 321 and the water pump 2; one end of the scale inhibition cover 33 is rotatably connected to the first side wall 321, and the other end is clamped and fixed to the second side wall 322.

[0089] In the above embodiment, the scale inhibition cover 33 is rotatably connected to the scale inhibition box body 32, which has higher flexibility and reliability in movement, and the scale inhibition cover 33 is rotatably connected to the first side wall 321. Since the first side wall 321 is located on the outside of the entire water pump bracket 4, the scale inhibition cover 33 will not interfere with the bracket body during opening, and the opening and closing are more convenient.

[0090] Preferably, in this embodiment, the rotation connection side of the cover body 331 and the scale inhibition box body 32 are integrally formed, the connection part of the two is reduced in thickness, and indentation design is performed, and the scale inhibition cover 33 can rotate relative to the indentation. Compared with the connection structure through the rotating shaft, the structure is simpler.

[0091] In some embodiments, the second side wall 322 includes a transverse support plate 3221 and a plurality of grid bars 3222. The transverse support plate 3221 is integrally formed on the water pump bracket 4 and located on the side close to the water inlet end 21 of the water pump 2. The plurality of grid bars 3222 are connected to the transverse support plate 3221 and arranged along the length direction of the transverse support plate 3221. The gap between adjacent two grid bars 3222 forms a water permeable hole 34. One end of the scale inhibition cover 33 is rotationally connected to the first side wall 321, and the other end is clamped to the transverse support plate 3221.

[0092] In the above embodiments, since the transverse support plate 3221 is integrally formed with the bracket body, the structural strength is higher, and the scale inhibition cover 33 is clamped to the transverse support plate 3221, so the stability is higher. By arranging the plurality of grid bars 3222, the water permeable hole 34 is formed by the gap between adjacent grid bars, without the need to additionally open the water permeable hole 34, which facilitates molding, simplifies the processing technology, and also reduces the weight of the entire water pump bracket 4.

[0093] In some embodiments, the first side wall 321 includes a transverse support rib, and one end of each of the plurality of grid bars 3222 is connected to the transverse support plate 3221 and the other end is connected to the transverse support rib. The grid bar 3222 is in a U shape, and the first side wall 321 and the second side wall 322 share the same set of grid bars 3222, which can further simplify the structure. Of course, in other alternative embodiments, the grid bar 3222 can also be a flat and straight rod, and the first side wall 321 can separately arrange the grid bar 3222 without sharing the same set of grid bars 3222 with the second side wall 322.

[0094] Preferably, the height of the transverse support rib is lower than that of the transverse support plate 3221, which provides space for installing the scale inhibition cover 33.

[0095] In some embodiments, the scale inhibition box body 32 and / or the scale inhibition cover 33 are provided with reinforcing ribs. The reinforcing ribs can improve the structural strength of the scale inhibition box body 32 and / or the scale inhibition cover 33.

[0096] Specifically, the scale inhibition box body 32 and the scale inhibition cover 33 are both provided with reinforcing ribs, and a plurality of reinforcing ribs are arranged along the length direction on the inner wall of the scale inhibition cover 33. The scale inhibition box body 32 is provided with a transversely arranged reinforcing rib, and the reinforcing rib is transversely connected between the plurality of grid bars 3222.
