Description

TECHNICAL FIELD

[0001] The present application relates to the field of humidifiers, in particular to a water inlet assembly and a humidifier. BACKGROUND

[0002] In the wide application of existing water pump technology, a common design is to set the water inlet surface of the water pump on the side, and the impeller is placed vertically. This design meets the needs of certain specific application scenarios to some extent, especially in systems that need to extract and transport water. The water inlet surface on the side makes the installation and layout of the water pump more flexible, and also facilitates certain pretreatment of the inlet flow, such as removing impurities in the water by adding a filter device.

[0003] However, this design has a significant disadvantage. Since the impeller is placed vertically, the water level in the water tank or pool drops to a low position. When the water level is lower than the highest point of the impeller inside the water pump, the water pump will lose its water pumping function, which means that a large amount of accumulated water at the bottom of the water tank cannot be effectively pumped and utilized by the water pump; this not only leads to waste of water resources, but also may cause water quality problems due to long-term accumulation of water. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0038] Embodiments of the present application are described below in detail with reference to examples shown in the drawings, wherein the same or similar numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are merely intended to explain the present application, and are not to be understood as limiting the present application.

[0039] In the description of the present application, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the purpose of facilitating the description of the present application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0040] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.

[0041] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0043] In existing humidifiers, the impeller of the water pump is vertical. This means that when the liquid level is lower than the height of the impeller, it cannot be completely submerged. Consequently, the water pump cannot extract water below this level, and the water remains in the humidifier, failing to be fully utilized. To address this, this application sets the water pump impeller horizontally. Compared to a vertically set impeller, a horizontally set impeller is lower in height, allowing it to extract more water and leaving less water remaining in the humidifier, thus ensuring full utilization of the water in the humidifier.

[0044] This application provides a water inlet assembly 100, which is mainly used in humidifiers. The water inlet assembly 100 includes a mounting component 110, a water pump 120, and a filter assembly 130.

[0045] The mounting component 110 has a receiving cavity 1102, and a water hole 1101 is provided on the outer wall of the mounting component 110. The receiving cavity 1102 communicates with the outside of the mounting component 110 through the water hole 1101. The water pump 120 is disposed in the receiving cavity 1102 and has an impeller. The impeller is arranged along a first direction. The filter assembly 130 is disposed at the position of the water hole 1101. The filter assembly 130 filters the water that enters the receiving cavity 1102 through the water hole 1101. The water hole 1101 is arranged along a second direction. The first direction and the second direction are perpendicular.

[0046] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the interior of the mounting component 110 is hollow, that is, the mounting component 110 has a receiving cavity 1102. The water pump 120 is installed in the receiving cavity 1102. In order to enable the receiving cavity 1102 to draw water from the outside of the mounting component 110, a water hole 1101 is opened on the outer wall of the mounting component 110. The receiving cavity 1102 is connected to the outside of the mounting component 110 through the water hole 1101, so that the water from the outside enters the receiving cavity 1102 through the water hole 1101, thereby providing the water pump 120 with the water to be drawn.

[0047] In some embodiments, the water pump 120 has an impeller, which is arranged along a first direction. It should be noted that the first direction is a horizontal direction, i.e. Figure 1 The horizontal plane where X is located means that the central axis of the impeller is set vertically, that is, the central axis of the impeller is located in the second direction. Since the impeller is set horizontally, water that is submerged in the horizontally set impeller can be drawn. Compared with the existing vertically set impeller, the horizontal impeller can draw water at a lower level, thereby improving the utilization rate of water in the humidifier and reducing the amount of water remaining in the humidifier.

[0048] Further, the water hole 1101 is arranged in a second direction, and it should be noted that the second direction is a vertical plane in which Z is located, and the vertical plane is perpendicular to the horizontal plane, that is, the water hole 1101 is arranged on the vertical side wall of the mounting member 110.

[0049] Since there are impurities in the water, in order to prevent the water containing impurities from entering the accommodation cavity 1102 and being pumped by the water pump 120, a filter assembly 130 is arranged at the inlet position of the water hole 1101. The filter assembly 130 filters the water entering the accommodation cavity 1102 through the water hole 1101, preventing impurities from entering the accommodation cavity 1102 and being pumped by the water pump 120.

[0050] It should be noted that the mounting member 110 has a water outlet pipe (not labeled in the figure), and the water pump 120 has a water outlet (not labeled in the figure). The water outlet of the water pump 120 is sealingly connected to the inlet of the water outlet pipe of the mounting member 110. The water pumped by the water pump 120 is discharged to the outside through the water outlet pipe, thereby realizing the pumping and discharging of the water used for humidification. It can be understood that the water discharged here is used for humidification.

[0051] Referring to FIGS. 1, 2, and 3, Figure 1 and Figure 3 It should be noted that the water hole 1101 has a plurality of shapes, such as rectangular, circular, etc. The shape of the water hole 1101 can be designed according to actual needs, and the specific shape is not limited.

[0052] In some embodiments, the mounting member 110 includes a shell member 111 and a cover member 112. Specifically, the shell member 111 has the accommodation cavity 1102, and the cover member 112 is detachably connected to the shell member 111, and the cover member 112 is used to close the accommodation cavity 1102.

[0053] Referring to FIGS. 1, 2, and 3, Figure 2 and Figure 3 It should be noted that the shell member 111 has the accommodation cavity 1102, and the water pump 120 is located in the accommodation cavity 1102. In order to facilitate the disassembly and cleaning of the water pump 120, the lower end of the accommodation cavity 1102 has an opening, and the cover member 112 closes the lower end of the accommodation cavity 1102. Specifically, the cover member 112 is detachably connected to the shell member 111, thereby facilitating the closing or opening of the lower opening of the accommodation cavity 1102, and thereby taking out the water pump 120 from the accommodation cavity 1102 for cleaning. In this embodiment, the cover member 112 is detachably connected to the shell member 111 by buckling.

[0054] The filter assembly 130 includes a grid plate 131 arranged on the mounting member 110 at the position of the water hole 1101. The grid plate 131 and the mounting member 110 define a placement groove 132, and the placement groove 132 is provided with a filter 133.

[0055] Referring to Figure 1 and Figure 2 As shown in the figure, the grid plate 131 is integrally formed with the shell 111, and the grid plate 131 is in the shape of "U", the grid plate 131 is located at the entrance of the water hole 1101, and the grid plate 131 and the plane where the water hole 1101 is located define a placement groove 132. In this embodiment, in order to prevent external impurities from entering the accommodation cavity 1102, a filter 133 is placed in the placement groove 132, which filters the water through the filter 133 to prevent external impurities from entering the accommodation cavity 1102. Further, the filter 133 can be plug-in set in the placement groove 132, and when it needs to be replaced, it only needs to be pulled out from the placement groove 132 for replacement, making it more convenient to replace and clean. Specifically, the filter 133 can be a filter component such as filter cotton, and the specific type is not limited here.

[0056] It should be noted that the above-mentioned grid plate 131 is a plate body with multiple holes, in this embodiment, external water can pass through the holes and be filtered by the filter 133, and finally enter the accommodation cavity 1102 through the water hole 1101 for pumping by the water pump 120.

[0057] The mounting member 110 can also be detachably mounted with a fixed shell 140, and the water pump 120 is mounted on the fixed shell 140. The fixed shell 140 includes a shell body 141, which has a mounting cavity, and the water pump 120 is arranged in the mounting cavity. The fixed shell 140 further includes a positioning assembly, and the shell body 141 is fixed in the mounting member 110 by the positioning assembly.

[0058] Referring to Figures 2 to 4 In order to fix the water pump 120 in the accommodation cavity 1102, the water pump 120 is fixedly mounted on the fixed shell 140, and then the fixed shell 140 is fixed in the accommodation cavity 1102 to achieve the fixed mounting of the water pump 120. Specifically, the fixed shell 140 has a mounting cavity adapted to the water pump 120 in the interior, the water pump 120 is fixedly mounted in the mounting cavity in the interior of the fixed shell 140, and then the shell body 141 is positioned by the positioning assembly. Since the bottom is closed by the cover 112, the shell body 141 is supported by the cover 112.

[0059] In one embodiment, the positioning assembly includes a plurality of positioning columns 142 arranged on the shell body 141, and the mounting member 110 has a plurality of positioning holes 143 formed in the inner wall, and the positioning columns 142 are arranged in the positioning holes 143.

[0060] Please continue to refer to Figures 2 to 4As shown, a plurality of positioning columns 142 are arranged on the upper surface of the shell 141, and a plurality of positioning holes 143 adapted to the positioning columns 142 are arranged on the inner bottom wall of the accommodating cavity 1102. During installation, the positioning columns 142 are inserted into the positioning holes 143, so that the positioning columns 142 and the positioning holes 143 are matched to position the shell 141. In this embodiment, the number of the positioning columns 142 and the positioning holes 143 is three, and in practice, the corresponding number can be selected according to the needs, which is not limited here.

[0061] Referring to Figure 5 As shown, a plurality of avoiding grooves 144 are arranged on the shell 141 and are communicated with the installation cavity.

[0062] In this embodiment, the water pump 120 has a water inlet, and the water inlet is located on the bottom surface of the water pump 120. In order not to hinder the water from entering the water pump 120 through the water inlet, there is a gap between the water inlet of the water pump 120 and the cover 112, so that the water can enter the water pump 120 through the water inlet. Further, in order to further facilitate the water to flow to the water inlet of the water pump 120, the avoiding grooves 144 are arranged on the bottom outer circumferential surface of the shell 141, so that the water can flow to the position of the water inlet of the water pump 120 through the avoiding grooves 144.

[0063] The water pump 120 comprises a mounting shell, a rotating driving member and an impeller. Specifically, the mounting shell has a water inlet, the rotating driving member is installed in the mounting shell, and the impeller is installed on the output shaft of the rotating driving member.

[0064] In this embodiment, the water inlet is arranged on the bottom surface of the mounting shell, and the water inlet is composed of a plurality of channels, and the number of the channels is not limited here. The impeller is horizontally placed, so that the water at a lower water level can be pumped. Further, the rotating driving member can be a motor, a motor or other components that can rotate the object.

[0065] The embodiment of the present application also provides a humidifier, which comprises the water inlet assembly 100 and the water tank 200, and specifically, the water tank 200 is used for storing water, and the water inlet assembly 100 is arranged inside the water tank 200.

[0067] Further, the inner bottom wall of the water tank 200 is provided with a groove 300, and the water inlet of the water pump 120 is located in the groove 300.

[0068] It can be understood that a groove 300 is arranged at a part of the inner bottom wall of the water tank 200, and the water inlet of the water tank 200 is located in the groove 300. When the water level of the water tank 200 is low, water will flow into the groove 300 first for the water inlet assembly 100 to suck, and the impeller of the water inlet assembly 100 is horizontally arranged, so that the water at the lowest water level can be sucked to the maximum, and the residual water in the water tank 200 is reduced.

[0069] Specifically, the water tank 200 includes a tank body 210 and a tank cover 220. The tank body 210 has a water storage cavity 230 for storing water. The groove 300 is arranged on the inner bottom wall of the water storage cavity 230. The water tank 200 is installed on the tank body 210.
