Description

Technical Field

[0001] This utility model relates to the field of push-button pumps, and more specifically, to a push-button type butterfly cap pump head. Background Technology

[0002] In the fields of daily chemicals and pharmaceuticals, pressure-operated butterfly cap pump heads are widely used for dispensing bottled fluid products, enabling convenient and precise dispensing.

[0003] Chinese Patent No. CN217674317U discloses a novel press pump head for a makeup remover bottle, comprising a press pump body, a flip cap, and a press plate. The press pump body is provided with a piston rod fixed to the press plate. A groove is formed on the top surface of the press pump body, and a connecting channel communicating with the bottom surface of the press pump body is formed at the bottom of the groove. A sealing block is fixedly connected to the bottom surface of the press plate. When the press pump body is in use, the sealing block disengages from the connecting channel. When the flip cap is in the closed state, the flip cap squeezes the press plate to drive the sealing block to close the connecting channel. A ring-shaped limiting barrier is fixedly connected to the flip cap, and a squeezing sponge abuts inside the limiting barrier. The squeezing sponge is used to squeeze the top surface of the press plate.

[0004] While existing patents attempt to address the issue of cleaning residual liquid from the pump head by squeezing a sponge to adhere to the top surface of the pump, significant technical shortcomings remain. The existing sponge is in a static attachment to the pump head. While it can initially absorb residual liquid, the sponge itself poses a risk of bacterial growth after absorbing the liquid. Furthermore, due to its continued contact with the pump head, these bacteria can easily re-contaminate the pump, failing to fundamentally guarantee pump head cleanliness and the hygiene of the contents. Simultaneously, the static attachment structure lacks flexibility. For the uneven surfaces at the pump head's outlet, thorough cleaning cannot be achieved through active wiping, leaving behind uncleaned areas. The long-term accumulation of residual liquid further exacerbates hygiene risks, severely impacting the pump's user experience and product quality stability. An improved solution that allows for flexible cleaning and easy disassembly and washing is urgently needed to address the problems of secondary bacterial contamination and incomplete cleaning caused by the static sponge attachment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure-operated butterfly cap pump head.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pressure-operated butterfly cap pump head, including a pump body, a pressing plate and a butterfly cap, wherein the pump body is connected to the pressing plate, the butterfly cap can be flipped to cover the pump body and is set corresponding to the pressing plate, and also includes a cleaning component, wherein the cleaning component includes a sponge, an iron sheet, a connecting rod and a magnet.

[0007] The magnet is fixed to the inside or outside of the top of the butterfly cap;

[0008] The iron sheet supports the sponge, and the iron sheet is arranged opposite to the magnet and is magnetically attracted to the inside of the cover.

[0009] One end of the connecting rod is fixedly connected to the iron sheet, and the other end passes through the top of the butterfly cover and extends to the outside of the top of the cover;

[0010] The connecting rod can drive the iron sheet to move axially and rotate circumferentially. When the connecting rod is pressed against the inside of the cover, the iron sheet causes the sponge to detach from the magnet and adhere to the pressing plate. Rotating the connecting rod can cause the sponge to rotate relative to the pressing plate to wipe away residual liquid. After the connecting rod is released, the iron sheet is re-attracted by the magnet under the action of magnetic force, causing the sponge to separate from the pressing plate.

[0011] The present invention is further configured such that: the magnet is fixed to the outer side of the top of the butterfly cover, and a rubber sealing sheet is provided on the side of the iron sheet facing the butterfly cover. When the iron sheet is attracted by the magnet under the action of magnetic force, the rubber sealing sheet presses against the inner side of the top of the butterfly cover to enhance the sealing between the iron sheet and the butterfly cover.

[0012] The present invention is further configured such that: a connecting tongue is provided on one side of the butterfly cover, and a buckle structure is provided on the connecting tongue; the pump body is provided with a buckle edge that is adapted to the buckle structure at the position where the connecting tongue is inserted; the butterfly cover is fixedly engaged with the buckle edge of the pump body through the buckle structure of the connecting tongue.

[0013] The present invention is further configured such that: one end of the connecting rod extending to the outer side of the top of the butterfly cover is provided with an annular flange gripping part, and the outer peripheral wall of the annular flange gripping part is provided with anti-slip texture.

[0014] The present invention is further configured such that: the annular flange holding part is connected to the end of the connecting rod by a thread, the annular flange holding part has an internal thread hole in the center of its inner side, and the corresponding end of the connecting rod has an external thread that matches the internal thread hole.

[0015] The present invention is further configured such that the butterfly cover is made of high-density polyethylene material and has a thickness of 1.5mm-3mm.

[0016] In summary, this utility model has the following beneficial effects: the cleaning component allows the sponge to thoroughly wipe away residual liquid from the pressing plate by pressing and rotating the connecting rod, thus improving the cleaning effect; the adsorption design of the iron sheet and magnet allows the sponge to separate from the pressing plate when not in use, reducing contamination.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0023] A type of pressure-operated butterfly cap pump head, such as Figure 1 As shown, it includes a pump body 1, a press plate 2, and a butterfly cover 3. The pump body 1 is connected to the press plate 2. The press plate 2 can be pressed on the pump body 1 to extract fluid. The butterfly cover 3 can be flipped to cover the pump body 1 and is set corresponding to the press plate 2.

[0024] like Figure 3 and Figure 4 As shown, the pressure-operated butterfly cap pump head also includes a cleaning component, which includes a sponge 4, an iron sheet 5, a connecting rod 6, and a magnet 7.

[0025] like Figure 3 and Figure 4 As shown, magnet 7 is a neodymium magnet, which is fixed to the inner or outer side of the top of the butterfly cover 3. In this embodiment, magnet 7 is fixed to the outer side of the top of the butterfly cover 3, which is convenient for installation, reduces interference with the internal structure, and saves internal space.

[0026] like Figure 3 and Figure 4 As shown, the iron sheet 5 supports the sponge 4, and the two are fixed together by adhesive. The iron sheet 5 and the magnet 7 are positioned opposite each other and are magnetically attracted to the inside of the cover. At the same time, a rubber sealing sheet 8 is provided on the side of the iron sheet 5 facing the butterfly cover 3 to press against the butterfly cover 3. When the iron sheet 5 is attracted by the magnet 7 under the action of magnetic force, the rubber sealing sheet 8 can tightly press against the inside of the butterfly cover 3, which enhances the sealing between the iron sheet 5 and the butterfly cover 3 and prevents dust from entering the butterfly cover 3.

[0027] like Figure 3 and Figure 4As shown, one end of the connecting rod 6 is fixedly connected to the iron plate 5, and the connection method can be welding or integral molding. The other end passes through the top of the butterfly cover 3 and extends to the outside of the top of the cover. The end of the connecting rod 6 extending to the outside of the top of the butterfly cover 3 is provided with an annular flange grip 12. The outer peripheral wall of the annular flange grip 12 is provided with anti-slip texture to facilitate the user's grip and operation. Furthermore, the annular flange grip 12 and the end of the connecting rod 6 are connected by threads. The annular flange grip 12 has an internal threaded hole in the center of its inner side, and the corresponding end of the connecting rod 6 has an external thread that matches the internal threaded hole. This connection method facilitates the disassembly and installation of the annular flange grip 12, and makes it easy to install cleaning components, including the rubber sealing sheet 8, onto the butterfly cover 3. More importantly, when the annular flange grip 12 and the connecting rod 6 are separated, the connecting rod 6 can be pulled out from the top of the butterfly cover 3, thereby pulling the iron sheet 5 and the sponge 4 out together, which facilitates thorough cleaning of the sponge 4 and avoids the problem of continuous reduction in cleaning effect due to the accumulation of dirt on the sponge 4. This connection method is a common connection method in the mechanical field, and the text description is clear enough, so it is not shown in the figure.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the connecting rod 6 can drive the iron sheet 5 to move axially and rotate circumferentially. When the connecting rod 6 is pressed against the inside of the cover, the iron sheet 5 will cause the sponge 4 to detach from the magnet 7 and adhere to the pressing plate 2. At this time, rotating the connecting rod 6 will cause the sponge 4 to rotate relative to the pressing plate 2, thereby wiping the residual liquid on the pressing plate 2 more thoroughly. When the connecting rod 6 is released, the iron sheet 5 will be re-attracted by the magnet 7 under the action of magnetic force, thereby causing the sponge 4 to separate from the pressing plate 2, avoiding long-term contact between the sponge 4 and the pressing plate 2 and causing contamination.

[0029] In addition, such as Figure 1 and Figure 2 As shown, the butterfly cover 3 is made of high-density polyethylene with a thickness of 1.5mm-3mm. In this embodiment, a thickness of 2mm is used. This material has good durability and drop resistance, meeting the needs of daily use. The thickness ensures durability and drop resistance while also ensuring the effective attraction of the magnet 7 to the iron sheet 5. A connecting tongue 9 is provided on one side of the butterfly cover 3, and a snap-fit ​​structure 10 is provided on the connecting tongue 9. The pump body 1 has a buckle 11 that matches the snap-fit ​​structure 10 at the position where it is inserted into the connecting tongue 9. The butterfly cover 3 is fixed to the pump body 1 by snapping the connecting tongue 9 with the buckle 11, realizing a reliable connection between the butterfly cover 3 and the pump body 1, and also facilitating the flipping operation of the butterfly cover 3.
