Description

Technical Field

[0001] This utility model relates to the field of pumps, and in particular to a 360° small-volume continuous spray pump and container. Background Technology

[0002] During use, the container contains a liquid product that needs to be pumped out. In existing technologies, the pump is usually equipped with a suction tube at the bottom. This means that during use, the product can only be placed upright, and the liquid product can be sucked out through the suction tube. However, in some usage scenarios, the container needs to be inverted. In this case, the liquid product inside the container flows to the opening side of the container under the influence of gravity. If only a suction tube extending into the container is provided, it cannot be used normally, which is inconvenient for users.

[0003] The prior art discloses an inverted spray device for a cosmetic spray pump (publication number CN210329725U). This structure directly uses two suction tubes and corresponding glass beads. In order to form a forward and inverted seal, the glass beads need to be sealed with the liquid outlet of the chamber. During the liquid inlet process, the liquid flow will cause the glass beads to flow towards the liquid outlet, thereby sealing the liquid outlet. (If forward and inverted use is not required, multiple irregularly shaped connecting grooves / notches are provided at the liquid outlet position, so that even if the glass beads move to the liquid outlet position, the liquid outlet will not be completely sealed.) This will affect the normal use of the pump. Utility Model Content

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1 to 6 As shown, a 360° small-volume continuous spray pump is characterized by comprising a pump body 1, wherein the pump body 1 is provided with a stepped portion 12 that abuts against the opening of a container 2. The pump body 1 has a main inlet hole 11 at the bottom, and a forward suction structure 3 and an inverted suction structure 4 connected to the main inlet hole 11 are provided on the lower side of the pump body 1. The forward liquid suction structure 3 includes a first one-way valve 31 and a first liquid inlet space 32. The first liquid inlet space 32 is connected to the inside of the container 2 at the bottom position through a first liquid inlet pipe 33. The inverted liquid suction structure 4 includes a second one-way valve 41 and a second liquid inlet space 42. The second liquid inlet space 42 is connected to the inside of the container 2 through a second liquid inlet channel 43 at the step portion 12. The first check valve 31 and the second check valve 41 respectively include a positive conical orifice 311 and an inverted conical orifice 411, and a first glass bead 312 and a second glass bead 412 located in the first liquid inlet space 32 and the second liquid inlet space 42. The first liquid inlet space 32 and the second liquid inlet space 42 are respectively provided with a first receiving hole 34 and a second receiving hole 44 for accommodating the first glass bead 312 and the second glass bead 412. The openings of the first receiving hole 34 and the second receiving hole 44 are respectively oriented towards the opening positions of the positive conical hole 311 and the inverted conical hole 411. When liquid enters the pump body 1 through the first inlet pipe 33 and the first check valve 31, the first glass bead 312 is located in the first receiving hole 34, and the second glass bead 412 is sealed with the inverted conical hole 411. When the liquid enters the pump body 1 through the second inlet pipe and the second check valve 41, the second glass bead 412 is located in the second receiving hole 44, and the first glass bead 312 is sealed with the positive conical hole 311.

[0021] At this time, a conical hole 311 and an inverted conical hole 411 are provided, which are sealed by the first glass bead 312 and the second glass bead 412 respectively. At the same time, a first receiving hole 34 and a second receiving hole 44 are provided to accommodate the first glass bead 312 and the second glass bead 412. When liquid enters through the conical hole 311 or the inverted conical hole 411, the first glass bead 312 or the second glass bead 412 is located in the corresponding first receiving hole 34 or second receiving hole 44, thereby avoiding the influence of liquid on the first glass bead 312 or the second glass bead 412. In this way, the first glass bead 312 or the second glass bead 412 will not move to the opening position of the conical hole 311 or the inverted conical hole 411, thereby ensuring the normal flow of liquid and ensuring the sealing effect on the other side, forming a forward or inverted spray.

[0022] In order to form the second liquid inlet space 42, in this embodiment, the pump body 1 includes a hollow outer shell 13 with an opening at the top. The stepped portion 12 has an inner step 121 that abuts against the opening at the top of the outer shell 13. The inner step 121 has an inner notch 122. The interior of the outer shell 13 is connected to the exterior of the outer shell 13 through the inner notch 122. The inner side of the outer shell 13 has a lower compression chamber 131. The lower compression chamber 131 is connected to the inner side of the outer shell 13 through a connecting portion 132. The connecting portion divides the interior of the outer shell 13 into an upper chamber and a lower chamber. The connecting portion has a connecting hole 133 for connecting the upper chamber and the lower chamber. The upper chamber has a pressing piston 134. The outer shell 13, the pressing piston 134, and the outer side of the lower compression chamber 131 form a second liquid inlet channel 43.

[0023] The outer shell 13 has an annular structure, with its top abutting against the stepped portion 12. An inner step 121 is provided on the inner side of the stepped portion 12, and the inner step 121 has an inner notch 122, so that the interior of the outer shell 13 can abut against the outer shell 13 through the inner notch 122. In the inverted state, the liquid in the container 2 can flow into the interior of the outer shell 13 through the inner notch 122 at the position of the inner step 121. A lower compression chamber 131 is provided inside the outer shell 13, and the side of the lower compression chamber 131 is connected to the inner side wall of the outer shell 13 through a connecting part. A connecting hole 133 is provided at the connecting part, so that the separated upper chamber and lower chamber are connected. The second one-way valve 41 is located in the lower chamber. Thus, a second liquid inlet channel 43 can be formed through the inner notch 122 of the stepped portion 12, the outer shell 13, and the connecting hole 133 of the connecting part. In the inverted state, the liquid can flow to the position of the second one-way valve 41 through the inner notch 122, the outer shell 13, and the connecting hole 133 of the connecting part, so that it can be used even in the inverted state. At this time, an annular gap is provided between the inner wall of the outer casing 13 and the outer wall of the lower compression chamber 131, so that the lower side of the lower compression chamber 131 can communicate with the connecting hole 133 through the annular gap.

[0024] In order to make the liquid flow in the second liquid inlet channel 43 smoother, in this embodiment, the step portion 12 also includes an outer step 123. A vertical portion 124 is provided between the inner step 121 and the outer step 123. The step portion 12 abuts against the inner sidewall of the container 2 at the position of the vertical portion 124. A gap is provided between the vertical portion and the outer sidewall of the outer shell 13. The inner notch 122 communicates with the inside of the container 2 through the gap. At this time, in order to ensure that when the step portion 12 is at the opening of the container 2, the inner notch 122 of the step portion 12 is connected to the inside of the container 2, a vertical portion 124 is provided on the lower side of the step portion 12. The step portion 12 abuts against the opening of the container 2 at the outer step 123 position and abuts against the inner side wall of the opening of the container 2 at the vertical portion 124 position, thereby completing the limiting between the step portion 12 and the opening of the container 2. A gap is provided between the inner side wall of the vertical portion 124 and the outer side wall of the outer shell 13, so that the inner notch 122 of the step portion 12 is located at the gap position. Thus, the inner side of the outer shell 13 is connected to the gap through the inner notch 122, thereby connecting with the inside of the container 2. In use, it can be ensured that the outer shell 13 and the inside of the container 2 are always in a state of communication. Therefore, when used upside down, it can be ensured that the liquid can smoothly enter the inner side of the outer shell 13 from the gap position through the inner notch 122.

[0025] In order to allow liquid to enter in the inverted state, in this embodiment, a first connector 5 is provided on the lower side of the outer shell 13. The first connector 5 includes a first annular portion that is fixedly connected to the outer shell 13. The inverted conical hole 411 is located at the position of the first connector 5. The second receiving hole 44 is located on the lower side of the lower compression chamber 131. The inverted conical hole 411 and the second receiving hole 44 are located on the same vertical axis. A second liquid inlet space 42 is formed between the lower side of the lower compression chamber 131 and the inverted conical hole 411.

[0026] The first connector 5 is fixed to the outer casing 13 via the first annular portion and is located on the lower side of the outer casing 13. This fixes the first connector 5 to the lower side of the outer casing 13. The inverted conical hole 411 is located at the position of the first connector 5, on the lower side of the outer casing 13. A gap is provided between the inverted conical hole 411 and the bottom of the lower compression chamber 131, thus forming a first liquid inlet channel communicating with the inverted conical hole 411. To seal the inverted conical hole 411, the second glass bead 412 is located on the upper side of the inverted conical hole 411, that is, between the upper side of the inverted conical hole 411 and the lower side of the upper compression chamber. At this time, an annular protrusion extends from the bottom of the upper compression chamber to form a second receiving chamber. The axis of the second receiving hole 44 is coaxial with the axis of the opening of the inverted conical hole 411. In the inverted state, the second glass bead 412 falls into the second receiving hole 44 under the action of gravity. The liquid can flow out through the second liquid inlet channel 43 at the position of the inverted conical hole 411. At this time, since the second glass bead 412 is in the second receiving hole 44, the liquid has little impact on the second glass bead 412 when it flows through this position due to the obstruction of the second receiving hole 44. In this way, the second glass bead 412 will not be flushed out of the second receiving hole 44 during use, thereby preventing the second glass bead 412 from sealing the opening of the inverted conical hole 411.

[0027] After the second connector 6 is installed, in order for the liquid flowing out of the opening of the inverted conical hole 411 to enter the main inlet hole 11, the main inlet hole 11 is located at the bottom of the lower compression chamber 131. The lower compression chamber 131 is connected to the outside through the main inlet hole 11. The first connector 5 is provided with a first through hole 51 corresponding to the main inlet hole 11. A one-way valve plate 52 is provided between the first through hole 51 and the main inlet hole 11. The liquid at the position of the first through hole 51 flows to the position of the main inlet hole 11 through the one-way valve plate 52. Both the inverted conical hole 411 and the first through hole 51 are located at the position of the first connector 5, and thus the two are connected. At this time, the first through hole 51 is positioned opposite to the main liquid inlet hole 11, and a one-way valve plate 52 is provided between them. This can be used to restrict the one-way valve plate 52 between the first through hole 51 and the main liquid inlet hole 11, and at the same time, a one-way flow structure can be formed. At this time, in order to ensure that the liquid enters the main liquid inlet hole 11 at the position of the one-way valve plate 52, several recesses are provided at the bottom of the main liquid inlet hole 11 to facilitate the flow of liquid.

[0028] In order to form a positive inlet check valve structure, in this embodiment, a second connector 6 is fixed to the lower side of the first connector 5. The second connector 6 includes a second annular portion fixed to the first connector 5. The positive conical hole 311 is located at the position of the second connector 6. The positive conical hole 311 is located below the inverted conical hole 411. A main inlet space 61 communicating with the main inlet hole 11 is formed between the first connector 5 and the second connector 6. An annular connecting portion is provided on the lower side of the second connector 6. The second connector 6 is fixed to the lower side of the first connector 5 via the second annular portion. At this time, the first connector 5 and the second connector 6 have a certain gap in the middle position, thereby forming a main liquid inlet space 61 that communicates with the main liquid inlet hole 11 (through the one-way valve plate 52). With the main liquid inlet space 61 as a reference, the positive conical hole 311 is located at the lower side of the main liquid inlet space 61, and the inverted conical hole 411 is located at the upper side of the main liquid inlet space 61. When the liquid flows out at the opening position of the positive conical hole 311 and the opening position of the inverted conical hole 411, it flows to the main liquid inlet space 61 and then flows to the main liquid inlet hole 11 through the one-way valve plate 52, thereby forming liquid inlet.

[0029] Furthermore, in order to form a positive inlet check valve structure, a third connector 7 is fixed at the annular connection position on the lower side of the second connector 6. The third connector 7 has an outer annular portion that is fixed to the annular connection portion of the second connector 6. A connection hole 71 is provided at the bottom of the outer annular portion. A connection post 72 is provided on the upper side of the connection hole 71 at the bottom of the outer annular portion. A lower inlet hole 73 communicating with the connection hole 71 is provided on the side of the connection post 72. A first receiving hole 34 is formed by the inward indentation on the upper side of the connection post 72. A first inlet space 32 is formed between the third connector 7 and the positive conical hole 311. The third connector 7 is fixed to the lower side of the second connector 6, thereby forming the liquid inlet position of the conical hole 311. At this time, the first glass bead 312 is located between the third connector 7 and the second connector 6. In the inverted state, the first glass bead 312 can seal the opening of the conical hole 311. In the upright state, the first glass bead 312 is located in the first receiving hole 34. Thus, the liquid flowing through this position has a smaller impact on the first glass bead 312, and will not cause the first glass bead 312 to move, thereby ensuring the normal liquid inlet process of the conical hole 311.

[0030] At this time, when setting the first receiving hole 34, in order to avoid affecting the liquid inlet process of the first liquid inlet space 32, a lower liquid inlet hole 73 communicating with the connecting hole 71 needs to be provided on the side of the connecting column 72, so as to ensure that the liquid entering at the position of the connecting hole 71 can flow into the first liquid inlet space 32 through the lower liquid inlet hole 73, thereby ensuring the entry of liquid under the normal use condition.

[0031] In the forward use, in order to draw out the liquid from the container 2, in this embodiment, a first liquid inlet pipe 33 is inserted into the connection hole 71 of the third connector 7, and the first liquid inlet pipe 33 and the lower liquid inlet hole 73 form a second liquid inlet channel 43.

[0032] In some embodiments, when liquid flows out from the opening of the conical hole 311, if the conical hole 311 and the inverted conical hole 411 are on the same axis, the liquid will flow directly to the second glass bead 412, which may affect the sealing effect of the second glass bead 412 on the inverted conical hole 411. Therefore, in this embodiment, the opening of the conical hole 311 and the opening of the inverted conical hole 411 are designed to be misaligned. The opening of the conical hole 311 is at least partially facing the inclined sidewall 8 of the inverted conical hole 411, and the opening of the inverted conical hole 411 is at least partially facing the inclined sidewall 8 of the conical hole 311. The openings of the conical hole 311 and the inverted conical hole 411 are offset (there is a gap between their axes). This design prevents the liquid flowing out from the openings of the conical hole 311 / inverted conical hole 411 from flowing directly to the second glass bead 412 / first glass bead 312, thus reducing the impact on the second glass bead 412 / first glass bead 312. At the same time, the opening of the conical hole 311 is at least partially facing the inclined sidewall 8 of the inverted conical hole 411, and the opening of the inverted conical hole 411 is at least partially facing the inclined sidewall 8 of the conical hole 311. This design slows down the flow rate of the liquid when it comes into contact with the inclined sidewall 8, resulting in a smoother flow of liquid in the main liquid inlet space 61, further reducing the impact on the first glass bead 312 / second glass bead 412.

[0033] At this point, the pressing piston 134 mentioned is used to control the volume change of the lower compression chamber 131, thereby creating a negative pressure to ensure that the liquid can flow through the main inlet space 61 and the one-way valve plate 52 to the lower compression chamber 131. The pressing piston 134 adopts the technical solution in the prior art, so it will not be described in detail here.

[0034] This application also provides an embodiment, including a container 2, which employs the 360° small-volume continuous spray pump described in the above embodiment.

[0035] At this point, the description of 360° mainly refers to the fact that the pump in this application can be used in both upright and inverted (vertically placed) states. Of course, in the tilted state, since the second inlet pipe and the inner notch 122 are located at the bottom and top of the container 2, as long as there is some liquid at that position, it can be used normally. The first glass bead 312 / second glass bead 412 are also in the first receiving hole 34 / second receiving hole 44 in the tilted state, so it will not affect normal use. In the horizontal placement state, the first glass bead 312 / second glass bead 412 may not be able to seal the positive conical hole 311 / inverted conical hole 411, which has a certain impact on normal use.

[0036] 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.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
