Description

Technical Field

[0001] The present application relates to the field of water intake equipment, and in particular to a water intake regulating device and a water intake device. Background Art

[0002] Existing laboratory water purifiers on the market typically have a switch-type water dispenser button: press to dispense water, and release to stop. However, laboratory users often have varying flow rate requirements when using water purifiers. For example, container cleaning requires a high flow rate, while cell culture or buffer preparation requires a low flow rate. Switch-type buttons cannot adjust the flow rate, failing to meet users' varying flow rate needs. Utility Model Content

[0003] The purpose of this application is to provide a water intake regulating device and a water intake device to change the water outlet speed.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, an embodiment of the present application provides a water intake regulating device, comprising a housing, a water intake mechanism disposed within the housing, and a rheostat connected in series with the water intake mechanism;

[0006] The housing is provided with a through-slot hole, and the housing is also slidably connected to a sliding component, the sliding component has an operating portion located outside the housing, the operating portion is connected to a connecting portion, one end of the connecting portion penetrates the slot hole and is connected to the slider of the rheostat;

[0007] The water intake regulating device is configured as follows: sliding the sliding component along the extension direction of the chute hole can change the current or voltage of the water intake mechanism, thereby changing the water outlet speed of the water intake mechanism.

[0008] In the above technical solution, the water intake mechanism is connected in series with the rheostat. Therefore, the voltage of the water intake mechanism or the current passing through the water intake mechanism can be changed by the slider on the rheostat, thereby achieving the purpose of changing the water outlet speed of the water intake mechanism. Moreover, the water outlet speed changes with the position of the slider on the rheostat, and the water outlet speed can be adjusted steplessly. The shell can protect the water intake mechanism and rheostat arranged inside. The operating part of the sliding component is arranged on the outside of the shell to facilitate the operator to use it to adjust the position of the slider on the rheostat, thereby changing the water outlet speed of the water intake mechanism. The water intake adjustment device provided by the above technical solution can meet the user's needs for adjusting the water outlet speed.

[0009] In some optional embodiments, the water intake mechanism includes a water outlet pump with adjustable power, and the water intake regulating device is configured to: change the power of the water outlet pump by sliding the sliding component;

[0010] And / or the water intake mechanism includes a water outlet valve with adjustable opening, and the water intake regulating device is configured to change the opening of the water outlet valve by sliding the sliding component.

[0011] In the above technical solution, the purpose of changing the water output of the water intake mechanism can be achieved by changing the power of the water outlet pump or the opening of the water outlet valve.

[0012] In some optional embodiments, two oppositely arranged connecting plates are further provided on the side of the operating portion facing the shell, and the connecting portion is located between the two connecting plates; a protrusion is provided at one end of the connecting plate away from the operating portion, and the protrusions of the two connecting plates protrude in opposite directions; the protrusion is located inside the shell, and the sliding component is connected to the shell by snap-fitting through the operating portion and the protrusion.

[0013] In the above technical solution, the sliding component and the housing are snap-fitted by positioning the operating portion outside the housing and the protruding portion inside the housing, which not only enables the connection between the housing and the sliding component but also does not affect the relative sliding between the housing and the sliding component.

[0014] In some optional embodiments, the protrusion has an inclined surface on a side facing away from the operating portion, and the inclined surface is configured to play a guiding role when the connecting plate extends into the sliding slot hole.

[0015] In the above technical solution, when the connecting plate is extended into the chute hole, the inclined surface of the protruding portion facing away from the operating portion can play a guiding role, thereby facilitating the insertion of the connecting plate into the chute hole.

[0016] In some optional embodiments, the protrusion is tilted toward one side of the operating portion so that the connecting plate can bend toward the other connecting plate during the process of being pulled out of the slide slot hole from the housing.

[0017] In the above technical solution, since the protrusion is tilted toward one side of the operating part, the two connecting plates can be deformed under the action of the shell when the sliding component is disassembled, so that the sliding component can be disassembled without damaging the sliding component or the shell.

[0018] In some optional embodiments, the protrusion has a first toothed surface on a side facing the operating portion, and the housing has a second toothed surface on an inner side; one of the first toothed surface and the second toothed surface has a plurality of ribs arranged along the extension direction of the chute hole, and the other has a plurality of grooves arranged along the extension direction of the chute hole;

[0019] The ribs can cooperate with the grooves at different positions, so that the sliding component and the housing are in different relative positions.

[0020] In the above technical solution, as the sliding component slides, the ribs can cooperate with the grooves at different positions, thereby limiting the relative movement of the sliding component and the shell, that is, the sliding component will not automatically change its position, and can automatically maintain the stability of the water outlet speed.

[0021] In some optional embodiments, an anti-slip rib is provided on a side of the operating portion facing away from the shell, and the anti-slip rib extends perpendicular to an extension direction of the sliding slot hole.

[0022] In the above technical solution, since the operating part is also provided with anti-slip ribs extending perpendicular to the extension direction of the slide slot hole, the user can more easily apply force to the operating part during use, thereby causing the sliding part to drive the slide to move to adjust the water outlet speed.

[0023] In some optional embodiments, a gasket is provided between the sliding component and the housing, and the gasket is a plastic structural member;

[0024] The sliding component is in contact with the gasket through a plane and can slide relative to each other on the plane;

[0025] And / or the housing and the gasket are in contact through a plane and can slide relative to each other on the plane.

[0026] In the above technical solution, the gasket is a plastic structural part with good self-lubricating properties. Therefore, a gasket is arranged between the sliding component and the shell, and the gasket is in sliding contact with one of the sliding component or the shell through a plane, which can reduce the friction that needs to be overcome when the sliding component and the shell slide relative to each other.

[0027] In some optional embodiments, the outer side of the shell has an outwardly protruding water retaining edge, the water retaining edge is arranged around the edge of the chute hole, and the gasket abuts against the water retaining edge.

[0028] In the above technical solution, since the outer side of the shell has an outwardly protruding water retaining edge, and the water retaining edge is arranged around the edge of the slide groove, the possibility of liquid entering the interior of the shell from the slide groove hole can be reduced; since the gasket abuts against the water retaining edge, on the one hand, the possibility of liquid entering the interior of the shell from the slide groove hole can be further reduced, and on the other hand, the contact area between the gasket and the shell can be made smaller, and when the gasket needs to slide relative to the shell, the friction force that needs to be overcome is smaller.

[0029] In a second aspect, an embodiment of the present application provides a water intake device, comprising a water source and the water intake regulating device provided in the first aspect, wherein the water inlet of the water intake mechanism is connected to the water source.

DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0044] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0046] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0047] The present application provides a water intake device, including a water source and a water intake regulating device. The water intake regulating device has a water intake mechanism 200, and the water inlet of the water intake mechanism 200 is connected to the water source. It should be noted that the water source does not only refer to liquid, but also includes a container for holding liquid. The connection between the water inlet of the water intake mechanism 200 and the water source means that the water inlet of the water intake mechanism 200 is connected to the container for holding liquid through a pipe or other structure, so that the liquid in the container can enter the water intake mechanism 200. The liquid in the container is not limited to water, but can also be other solutions required for use in the laboratory; that is, the water intake device provided by the present application can be used not only in the case where the liquid is water, but also in the case where the liquid is an aqueous solution of other substances, or other solutions.

[0048] like Figure 2 As shown, the water intake regulating device also has a rheostat 300 connected to the same circuit as the water intake mechanism 200, and by changing the position of the slider 310 in the rheostat 300, the voltage or current passing through the water intake mechanism 200 can be changed, thereby changing the water outlet speed of the water intake mechanism 200. Optionally, the water intake mechanism 200 is connected in series with the resistor. Therefore, the water intake regulating device and water intake device provided by the present application can achieve the function of changing the water outlet speed. And because the water outlet speed of the water intake mechanism 200 can be adjusted by changing the position of the slider 310 in the rheostat 300, the water outlet speed can be adjusted steplessly, that is, the water outlet speed can be changed smoothly and continuously.

[0049] In some embodiments, the water intake regulating mechanism further includes a housing 100, such as Figure 1 and Figure 3 As shown, the water intake mechanism 200 and the rheostat 300 are arranged in the housing 100, and the housing 100 can protect the water intake mechanism 200 and the rheostat 300. The housing 100 is also slidably connected to a sliding member 400, and the sliding member 400 has an operating portion 410 located outside the housing 100 and a connecting portion 420 connected to the operating portion 410, as shown in FIG. Figure 4 and Figure 5As shown, the connecting portion 420 is used to connect the slider 310 of the resistor located in the housing 100, so that the user can change the position of the slider 310 by sliding the operating portion 410 located outside the housing 100, thereby changing the water outlet speed. The rheostat 300 in this application can be either a sliding rheostat 300 in the prior art, or other structures that can realize the functions of the existing sliding rheostat 300, that is, the rheostat 300 in this application can be either a sliding rheostat 300 sold in the market, or a device assembled according to the principle of the sliding rheostat 300 that can realize the functions of the sliding rheostat 300. Since the sliding rheostat 300 is already a prior art, those skilled in the art can set the position of the rheostat 300 and the related circuits according to the inventive concept of this application.

[0050] In some embodiments, as Figure 2 As shown, the housing 100 is composed of a front housing 110 and a rear housing 120 , so as to facilitate the processing and manufacturing of the housing 100 .

[0051] like Figures 4 to 7 As shown, in some embodiments, the connecting portion 420 is provided with a hole-like structure, and the hole-like structure has an opening at one end away from the operating portion 410. The slide 310 has a columnar structure that can extend into the hole-like structure. When the sliding member 400 is connected to the housing 100, the columnar structure of the slide 310 is located inside the hole-like structure. This allows the slide 310 to move with the sliding member 400 during movement, thereby changing the position of the slide 310 within the rheostat 300 and achieving the purpose of changing the water outlet speed.

[0052] It is easy to understand that the connection portion 420 and the operating portion 410 are fixedly connected. In some embodiments, the connection portion 420 and the operating portion 410 are integrally formed structural members. Since the connection portion 420 is connected to the slider 310 in the variable resistor 300 located inside the housing 100 and is also connected to the operating portion 410 located outside the housing 100, the connection portion 420 needs to pass through the housing 100. In some embodiments, such as Figure 2 and Figure 4As shown, the housing 100 is provided with a through-groove hole 111 for the connection portion 420 to pass through. That is, the interior and exterior of the housing 100 are connected through the groove hole 111, and one end of the connection portion 420 penetrates the groove hole 111 and connects to the slider 310 of the rheostat 300. Furthermore, the groove hole 111 has a larger dimension in the direction in which the sliding component 400 and the housing 100 slide relative to each other. That is, the groove hole 111 extends in the direction in which the sliding component 400 and the housing 100 slide relative to each other, so that the connection portion 420 moves within the groove hole 111 during the sliding process of the sliding component 400. In other words, sliding the sliding component 400 along the extension direction of the groove hole 111 can change the current or voltage of the water intake mechanism 200, thereby changing the water outlet speed of the water intake mechanism 200.

[0053] exist Figure 2 In the embodiment shown, the slide slot hole 111 is provided on the front shell 110. Figure 2 、 Figure 4 and Figure 8 As shown, the slide slot 111 is rectangular, and the longer side of the slide slot 111 extends along the direction in which the sliding component 400 slides relative to the housing 100. In other embodiments, the slide slot 111 may also be a structure of other shapes, such as a long waist-shaped hole.

[0054] In some embodiments, as Figure 2 As shown, the water intake mechanism 200 includes a water outlet pump 210 and a water outlet valve 220 , and the water outlet valve 220 is connected to the water outlet of the water outlet pump 210 .

[0055] In some embodiments, the power of the outlet pump 210 can be adjusted. It is readily understood that by varying the power of the outlet pump 210, the water delivery rate of the outlet pump 210 can be varied. In this embodiment, the power of the outlet pump 210 can be adjusted by changing the position of the slider 310 within the rheostat 300, thereby varying the voltage across the outlet pump 210 or the current flowing through the outlet pump 210 to achieve the desired power. In other words, the technical solution provided in this embodiment varies the power of the outlet pump 210, thereby varying the water delivery rate, by sliding the sliding member 400.

[0056] In some embodiments, the opening of the outlet valve 220 is adjustable. Different openings of the outlet valve 220 result in different water outlet speeds. The outlet valve 220 can employ an NCNV series electric needle valve, such as that provided by Shanghai Yiyang Industrial Co., Ltd. The opening of the outlet valve 220 can be varied by changing the voltage across the outlet valve 220 or the current flowing through the outlet valve 220. In other words, the technical solution provided in this embodiment utilizes a sliding member 400 to adjust the opening of the outlet valve 220, thereby varying the water outlet speed.

[0057] In some embodiments, as Figure 1 As shown, an anti-slip rib 411 is provided on the side of the operating portion 410 facing away from the shell 100. The anti-slip rib 411 extends perpendicular to the extension direction of the slide slot 111 to facilitate the user to apply force to the operating portion 410, thereby causing the sliding component 400 to drive the slide 310 to move.

[0058] In some embodiments, as Figure 6 and Figure 7 As shown, two oppositely disposed connecting plates 430 are further provided on the side of the operating portion 410 facing the housing 100. The two connecting plates 430 are each connected to a longer side of the slide slot hole 111, and the connecting portion 420 is located between the two connecting plates 430. The connection with the housing 100 is achieved through the two connecting plates 430, making the connection between the sliding component 400 and the housing 100 more reliable.

[0059] In some embodiments, a protrusion 440 is provided on one end of the connecting plate 430 away from the operating portion 410, and the protrusions 440 of the two connecting plates 430 protrude in opposite directions; when the sliding member 400 is connected to the housing 100, the protrusion 440 is located inside the housing 100. It is understood that since the operating portion 410 is located outside the housing 100 and the protrusion 440 is located inside the housing 100, the sliding member 400 can be connected to the housing 100 by snapping together the operating portion 410 and the protrusion 440. In this embodiment, the sliding member 400 and the housing 100 are connected by snapping together, and can slide relative to each other along the extension direction of the slide slot 111.

[0060] Furthermore, in some embodiments, the connecting plate 430 is further configured to extend into the chute hole 111 through elastic deformation, after which the protrusion 440 is clamped on the inner side of the housing 100. During the installation of the sliding component 400, the connecting plate 430 can be directly inserted into the chute hole 111. The protrusion 440 exerts a force on the connecting plate 430 under the action of the hole wall of the chute hole 111, causing the connecting plate 430 to bend and deform. After the protrusion 440 reaches the interior of the housing 100, the protrusion 440 is no longer restricted by the hole wall of the chute hole 111, so the bending deformation of the connecting plate 430 disappears, causing the protrusion 440 to be clamped on the inner side of the housing 100. In this manner, the installation process of the sliding component 400 and the housing 100 is relatively simple and convenient. In this embodiment, the operating portion 410 and the connecting plate 430 can be an integral structural component obtained by injection molding.

[0061] In some embodiments, the protrusion 440 has a sloped surface on the side facing away from the operating portion 410, and the sloped surface is configured to play a guiding role in the process of the connecting plate 430 extending into the slide hole 111, that is, in the process of inserting the connecting plate 430 into the slide hole 111, when the shell 100 contacts the sloped surface of the protrusion 440, the force applied by the protrusion 440 will cause the two connecting plates 430 to bend in a direction close to each other, so that the connecting portions 420 of the two connecting plates 430 can be smoothly inserted into the slide hole 111.

[0062] In some embodiments, the protrusion 440 is tilted toward one side of the operating portion 410 so that the connecting plate 430 can be bent toward the other connecting plate 430 during the process of being drawn out of the sliding slot 111 from the housing 100. Figures 5 to 7 The embodiment shown is not difficult to understand. Since the sliding component 400 is connected to the shell 100 through the operating part 410 and the protrusion 440, the side of the protrusion 440 facing the operating part 410 is the side in contact with the shell 100. By tilting this side, when a force away from the shell 100 is applied to the operating part 410, the two connecting plates 430 can be deformed toward the other connecting plate 430, so that the protrusion 440 can enter the slide slot hole 111 and then separate from the shell 100. Therefore, the sliding component 400 can be disassembled more conveniently without damaging the shell 100 or the sliding component 400.

[0063] In some embodiments, the protrusion 440 has a first toothed surface 441 on the side facing the operating portion 410, and a second toothed surface 112 is provided on the inner side of the shell 100; one of the first toothed surface 441 and the second toothed surface 112 has a plurality of ribs 442 arranged along the extension direction of the slide slot hole 111, and the other has a plurality of grooves arranged along the extension direction of the slide slot hole 111; and the ribs 442 can cooperate with the grooves at different positions to make the sliding component 400 and the shell 100 in different relative positions, that is, when the sliding component 400 slides to different positions relative to the shell 100, the ribs 442 at different positions can cooperate with the grooves at different positions. When the ribs 442 cooperate with the grooves, they can play a role in limiting the relative sliding of the sliding component 400 and the shell 100. Among them, limiting the relative sliding of the sliding member 400 and the housing 100 means that the sliding member 400 and the housing 100 cannot automatically undergo relative displacement. Relative displacement can only occur when the user applies external force, thereby automatically maintaining the stability of the water outlet speed and preventing the water outlet speed from automatically changing. It is not difficult to understand that during the process of separation of the rib 442 from the groove, the protrusion 440 or the connecting plate 430 will cause deformation. When the rib 442 and the groove are in a mutually mating position, the deformation of the protrusion 440 and the connecting plate 430 is restored, so that the rib 442 is within the groove.

[0064] In some embodiments, ribs 442 may be provided on the first toothed surface 441, and grooves may be provided on the second toothed surface 112. In other embodiments, ribs 442 may be provided on the second toothed surface 112, and grooves may be provided on the first toothed surface 441. Furthermore, the surface of the ribs 442 is cylindrical, and the surface of the groove is also cylindrical, so that the ribs 442 and the groove are separated from each other. Of course, the surfaces of the ribs 442 and the groove may also have other shapes, such as spherical surfaces.

[0065] In some embodiments, in order to make the relative sliding between the sliding component 400 and the housing 100 smoother, as shown in FIG. Figure 2 and Figure 5 As shown, a gasket 500 made of plastic is provided between the sliding component 400 and the housing 100 . The self-lubricating property of the plastic material can reduce the friction of the relative sliding between the sliding component 400 and the housing 100 .

[0066] In some embodiments, the sliding component 400 and the gasket 500 are in contact with each other through a plane and can slide relative to each other on the plane; in this embodiment, the gasket 500 can be fixed relative to the housing 100 and slide relative to the sliding component 400. In some embodiments, the housing 100 and the gasket 500 are in contact with each other through a plane and can slide relative to each other on the plane; in this embodiment, the gasket 500 can be fixed relative to the sliding component 400 and slide relative to the housing 100. In other embodiments, the gasket 500 can be a thin sheet-like structure, that is, both sides of the gasket 500 are flat, with one side in contact with the sliding component 400 and the other side in contact with the housing 100. The gasket 500 can slide relative to the housing 100 or move relative to the sliding component 400.

[0067] In some embodiments, the outer side of the housing 100 further has a water retaining edge 113 protruding outward. Figure 9 As shown, the water retaining edge 113 is arranged around the edge of the chute hole 111, that is, the water retaining edge 113 surrounds the chute hole 111 inside to reduce the possibility of liquid entering the chute hole 111, so as to avoid affecting the circuit inside the inner shell 100. Furthermore, the gasket 500 abuts against the water retaining edge 113, which can, on the one hand, further reduce the possibility of liquid entering the shell 100 from the chute hole 111, and on the other hand, can make the contact area between the gasket 500 and the shell 100 smaller, and when the gasket 500 needs to slide relative to the shell 100, the friction force that needs to be overcome is smaller. Further, as Figure 2 As shown, the outer dimensions of the gasket 500 are larger than the outer dimensions of the slide hole 111. Only a smaller through hole is provided on the gasket 500 for the connecting portion 420 of the sliding component 400 to pass through. The rest of the gasket 500 covers the slide hole 111 to reduce the possibility of liquid entering the slide hole 111.

[0068] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
