Description

Technical Field

[0001] This utility model relates to the field of daily chemical pump head technology, specifically to a pump head assembly with high barrier performance. Background Technology

[0002] A cosmetic pump head mainly consists of a pump body, a compression head, a spring, and seals. In use, pressing the compression head compresses the spring, pushing the liquid inside the pump body through the seals and ejecting it.

[0003] A novel pump head for daily chemical detergents, disclosed in CN207129375U, includes a pump cover, a bottle cap, a pressing piston, a spring, a hydraulic cylinder, an upper valve core, a lower valve core, a suction tube, a fixing ring, and a bottle cap sealing ring. The fixing ring secures the hydraulic cylinder to the bottle cap and presses the pressing piston (containing the upper valve core) into the hydraulic cylinder. The hydraulic chamber is sealed by the pressing piston and the thin-walled skirt-shaped sealing ring on the fixing ring, simultaneously assembling the hydraulic cylinder assembly onto the bottle cap. An upper valve core blocking ring is installed in the inner hole of the pressing piston to block the upper valve core at the lower end of the pressing piston, maintaining it in the same position. Forced demolding is used for ejection from the plastic molding die, simplifying mold making. During assembly, a press-fitting machine is used, pressing in through piston deformation. This design can be widely used in the packaging of daily chemical products, is economical and practical, reduces assembly workload, and can greatly save materials and labor time, making it worthy of promotion.

[0004] The shortcomings of the existing technology: During the use of existing pump heads for daily chemical products, the daily chemical products are prone to condensation on the inner wall of the pump head's discharge end, which will cause blockage and make it difficult to clean the condensed daily chemical products. This will affect the smooth operation of the pump head and consequently affect the use of subsequent daily chemical products. Utility Model Content

[0005] Therefore, this utility model provides a pump head assembly with high barrier performance to solve the problem in the prior art where the inability to clean the inner wall of the pump head discharge end leads to the easy blockage of the inner wall of the pump head discharge end by condensed daily chemical products, which affects the use of subsequent daily chemical products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pump head assembly with high barrier performance, comprising a pump head body, and further comprising:

[0007] The cleaning mechanism is located on the outside of the discharge end of the pump head body and is used to clean the inner wall of the discharge end of the pump head body.

[0008] The cleaning mechanism includes a mounting plate, a rotating shaft rotatably mounted on the top of the inner wall of the mounting plate, a transmission gear fixedly sleeved on the outer side of one end of the rotating shaft, a scraper fixedly sleeved on the outer side of one end of the rotating shaft passing through the mounting plate, a rotating gear ring rotatably mounted on the bottom of the inner wall of the mounting plate and meshing with the transmission gear, and cleaning plates fixedly mounted on the top and bottom of the inner side of the rotating gear ring.

[0011] Preferably, a traction spring is fixedly installed on the bottom inner wall of the upper valve plate, and a lower valve plate is fixedly installed on the bottom of the traction spring. The outer wall of the lower valve plate is movably connected to the bottom inner wall of the fixed sleeve.

[0012] Preferably, the mounting sleeve is fixedly sleeved to the outside of the discharge end of the pump cover, and an adjustment knob is rotatably installed on the inner wall of one top end of the mounting sleeve. The bottom of the adjustment knob extends into the inner side of the mounting sleeve and is fixedly sleeved with a drive gear.

[0013] Preferably, a driven gear is fixedly sleeved on the outer side of the end of the rotating shaft near the transmission gear, and the driven gear meshes with the driving gear.

[0014] Preferably, the inner diameter of the mounting sleeve is the same as the inner diameter of the outlet end of the pump cover, the left vertical section of the cleaning plate is set as a fan-shaped structure, and the outer wall of the cleaning plate is movably connected to the inner wall of the discharge end of the pump cover.

[0015] Preferably, the height of the scraper is greater than the diameter of the inner wall of the mounting sleeve, and the pump head body is made of polyvinylidene chloride.

[0016] This utility model has the following advantages:

[0017] This invention utilizes the rotation of an adjustment knob, which, through the meshing of the driving and driven gears and the transmission action of the rotating shaft and transmission gears, allows the rotating gear ring to rotate inside the mounting sleeve.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1 This utility model provides a pump head assembly with high barrier performance, including a pump head body 1, and further including:

[0029] The cleaning mechanism 2 is located on the outside of the discharge end of the pump head body 1 and is used to clean the inner wall of the discharge end of the pump head body 1.

[0030] To facilitate cleaning of the inner wall of the discharge end of the pump head body 1, such as... Figure 1-3 and Figure 5 As shown, the cleaning mechanism 2 includes a mounting plate 201. A rotating shaft 202 is rotatably mounted on the top of the inner wall of the mounting plate 201. A transmission gear 204 is fixedly sleeved on the outer side of one end of the rotating shaft 202. A scraper 205 is fixedly sleeved on the outer side of one end of the rotating shaft 202 passing through the mounting plate 201. A rotating gear ring 208 that meshes with the transmission gear 204 is rotatably mounted on the bottom of the inner wall of the mounting plate 201. Cleaning plates 209 are fixedly mounted on the top and bottom of the inner side of the rotating gear ring 208. The rotation of the rotating shaft 202 causes the transmission gear 204 to rotate. Through the meshing action between the gear components, the rotating gear ring rotates inside the mounting plate 201, so that the cleaning plate 209 can clean the inner wall of the discharge end of the pump head body 1.

[0031] For convenient use of daily chemical products, such as Figure 1-2 and Figure 4 As shown, the pump head body 1 includes a pump cover 101. A movable rod 102 is fixedly installed at the bottom of the pump cover 101. A connecting sleeve 103 is movably sleeved on the outer side of the movable rod 102. A cover plate 104 is threaded on the inner wall of the bottom of the connecting sleeve 103. A fixed sleeve 105 is movably sleeved on the outer side of the movable rod 102 on the inner side of the cover plate 104. An upper valve plate 106 is movably inserted into the bottom of the movable rod 102. A sealing sleeve 107 is provided between the outer wall of the upper valve plate 106 and the inner wall of the fixed sleeve 105. A traction spring 108 is fixedly installed on the inner wall of the bottom of the upper valve plate 106. A lower valve plate 109 is fixedly installed on the bottom of the traction spring 108. The outer wall of the lower valve plate 109 is movably connected to the inner wall of the bottom of the fixed sleeve 105. By pressing the pump cover 101, the upper valve plate 106 can be pushed to move, so that the daily chemical products inside the fixed sleeve 105 can flow out through the pump cover 101.

[0032] To provide power for the rotation of the cleaning plate 209, such as Figure 2-3 and Figure 5 As shown, the mounting sleeve 201 is fixedly sleeved on the outside of the discharge end of the pump cover 101. An adjustment knob 206 is rotatably mounted on the inner wall of one end of the top of the mounting sleeve 201. The bottom of the adjustment knob 206 extends into the inner side of the mounting sleeve 201 and is fixedly sleeved with the drive gear 207. A driven gear 203 is fixedly sleeved on the outer side of the end of the rotating shaft 202 near the transmission gear 204. The driven gear 203 meshes with the drive gear 207. The inner diameter of the mounting sleeve 201 is the same as the inner diameter of the discharge end of the pump cover 101. The left vertical section of the cleaning plate 209 is set as a fan-shaped structure. The outer wall of the cleaning plate 209 is movably connected to the inner wall of the discharge end of the pump cover 101. The rotation of the adjustment knob 206, through the meshing action between the drive gear 207 and the driven gear 203, causes the rotating shaft 202 to rotate, thereby providing power for the rotation of the cleaning plate 209.

[0033] In order to make the pump head body 1 have high barrier performance, such as Figure 1-2 and Figure 4 As shown, the height of the scraper 205 is greater than the diameter of the inner wall of the mounting sleeve 201. The pump head body 1 is made of polyvinylidene chloride. The scraper 205 can clean the outer wall of the mounting sleeve 201. At the same time, the pump head body 1 made of polyvinylidene chloride has high barrier properties, which makes it stable for use in the dispensing of daily chemical products or medicines.

[0034] The specific implementation scenario is as follows: When using the pump head body 1, pressing the pump cover 101 can drive the movable rod 102 to move downward, which in turn can push the upper valve plate 106 to move downward, thereby opening the gap between the bottom of the upper valve plate 106 and the sealing sleeve 107. This allows the daily chemical products filled in the gap between the fixed sleeve 105 and the bottom of the sealing sleeve 107 to enter the movable rod 102 through the holes at both ends of the upper valve plate 106, and then be squeezed out through the inner wall of the pump cover 101. At the same time, after releasing the pump cover 101, under the action of the traction spring 108, the upper valve plate 106 can be stored inside the sealing sleeve 107, and the lower valve plate 109 moves upward, allowing the bottled daily chemical products or medicines connected to the pump head body 1 to enter the fixed sleeve 105. Repeating the above operation allows the daily chemical products or medicines to be taken out.

[0035] After the daily chemical products are used, rotating the adjustment knob 206 causes the drive gear 207 to rotate. Through the meshing of the gear components, the driven gear 203 rotates, which in turn causes the rotating shaft 202 to rotate, which in turn causes the transmission gear 204 to rotate. Through the meshing of the gear components, the rotating gear ring 208 rotates inside the mounting sleeve 201, which allows the two cleaning plates 209 to clean the inner wall of the pump cover 101 discharge end. At the same time, the rotation of the rotating shaft 202 causes the scraper 205 to clean the outer wall of the mounting sleeve 201. This prevents residual daily chemical products from condensing on the inner wall of the pump cover 101 discharge end and causing blockage. This ensures that the inner wall of the pump cover 101 is unobstructed and can meet the needs of subsequent daily chemical product use. This embodiment specifically solves the problem in the prior art that the inner wall of the discharge end of the pump head assembly of daily chemical products is easily blocked by the condensation of residual products, which affects the use of subsequent daily chemical products.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
