Description

Technical Field

[0001] This invention relates to the field of pump technology, and in particular to a pump and a bottle for daily chemical products. Background Technology

[0002] Press pumps are widely used in the packaging of toiletries, cosmetics, and cleaning products. By pressing, a measured amount of lotion, hand soap, shampoo, and other daily chemical products can be dispensed from the bottle.

[0003] Chinese utility model patent CN218056507U discloses a press pump with adjustable output, including a pump body, a push head, an adjusting component, and an adjusting structure. The push head is connected to a liquid dispensing tube and is slidably mounted on the pump body. The adjusting component is mounted on the pump body. The adjusting structure includes a limiting structure and a limiting part that can cooperate with the limiting structure. One of the limiting structure and the limiting part is located on the push head, and the other is located on the adjusting component. The limiting structure includes at least two locking positions to cooperate with the limiting part to form at least two different sliding limiting strokes. The adjusting component can move relative to the push head so that the limiting part can form limiting cooperation with different locking positions, limiting the push head to at least two different pressing strokes, thereby adjusting the downward movement of the liquid dispensing head and thus adjusting the output of the press pump. However, the adjusting component requires a small rotation angle when rotating, and it is difficult to accurately adjust the position of the limiting structure by hand, making it difficult to accurately align the limiting structure with the limiting part, which is inconvenient for switching the output of the press pump. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing press pump is not convenient to accurately adjust the position of the limiting structure connected to the pressing part during use, which makes it difficult for the limiting structure to be accurately aligned with the limiting part, and makes it inconvenient to switch the liquid output of the press pump.

[0005] The push pump of the present invention includes: Pump body, with mounting holes; The liquid collection tube includes a first mounting section, an external gear ring section, a second mounting section, and a third mounting section arranged sequentially from top to bottom, wherein the third mounting section is slidably inserted into the mounting hole; The barrel body has its bottom rotatably fitted onto the first mounting section, and the barrel wall of the barrel body includes an internal gear ring section; Planetary carrier, which is rotatably mounted on the second mounting section; Multiple planetary gears are located inside the barrel cavity of the barrel body and rotatably connected to the planet carrier. Each planetary gear, the planet carrier, the internal gear ring segment, and the external gear ring segment form a planetary gear reduction mechanism. The planetary carrier and the pump body are provided with multiple adjustment slots, and another one is connected to a limiting protrusion. When the barrel is rotated, the planetary gear reduction mechanism drives the planetary carrier to rotate, so that the limiting protrusion can be vertically aligned with any one of the adjustment slots.

[0006] As an optional solution, the planetary carrier is a circular plate, the limiting protrusion is provided at the lower end of the planetary carrier, and the adjusting groove is provided at the upper end of the pump body; The barrel wall of the barrel body also includes a shielding section connected to the lower end of the internal gear ring section, and the planetary carrier is disposed in the barrel cavity of the shielding section, with the outer peripheral side of the planetary carrier slidingly engaged with the inner sidewall of the shielding section.

[0007] As an optional solution, a sealing ring is fitted around the outer periphery of the planetary carrier, and the sealing ring abuts against the barrel wall of the shielding section.

[0008] Alternatively, the barrel can be a transparent barrel.

[0009] As an optional solution, two limiting protrusions are provided, and the two limiting protrusions are arranged symmetrically at the center, with the center point of the two limiting protrusions located on the central axis of the liquid collection tube. The regulating tank includes multiple pairs of tanks arranged in a row. The tanks in the same pair have the same depth. The two regulating tanks in the same pair are arranged symmetrically at the center. The center point of symmetry of the same pair of regulating tanks is located on the central axis of the liquid collection tube.

[0010] As an optional embodiment, the liquid collection tube includes a tube body and an outer sleeve. The outer sleeve is fixedly sleeved on the upper outer side of the tube body. The first mounting section, the outer toothed ring section, and the second mounting section are formed in the outer sleeve. The lower part of the tube body forms the third mounting section.

[0011] As an optional embodiment, the liquid dispensing tube further includes a pressing part, which is connected to the upper end of the tube body. At least a portion of the pressing part has a receiving space with the barrel body. The pressing pump further includes an elastic resistance-increasing element, which is disposed in the receiving space. The lower end of the elastic resistance-increasing element abuts against the barrel body, and the upper end of the elastic resistance-increasing element abuts against the pressing part.

[0012] As an optional solution, the elastic resistance-increasing component is an elastic ring, which is fixed to one end of the barrel facing the receiving space, and the pressing part is fixed with a protrusion at one end facing the receiving space, the protrusion pressing against a part of the ring.

[0013] As an optional embodiment, the pressing part includes a body part and a liquid outlet part, the liquid outlet part having a liquid outlet hole communicating with the tube body, and a portion of the liquid outlet part protruding into the receiving space to form the protrusion part.

[0014] The present invention also provides a daily chemical product bottle, including the above-mentioned press pump.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The press pump of the present invention includes a pump body, a liquid dispensing tube, a barrel, a planetary carrier, and multiple planetary gears. The pump body has a mounting hole. The liquid dispensing tube includes a first mounting section, an external gear ring section, a second mounting section, and a third mounting section arranged sequentially from top to bottom. The third mounting section slides through the mounting hole. The bottom of the barrel is rotatably fitted onto the first mounting section. The barrel wall includes an internal gear ring section. The planetary carrier is rotatably fitted onto the second mounting section. Multiple planetary gears are located inside the barrel cavity of the barrel and rotatably connected to the planetary carrier. Each planetary gear, planetary carrier, internal gear ring section, and external gear ring section forms a planetary gear reduction mechanism. One of the planetary carrier and the pump body is provided with multiple adjustment slots, and the other is connected to a limiting protrusion. When the barrel is rotated, the planetary gear reduction mechanism drives the planetary carrier to rotate, so that the limiting protrusion can be vertically aligned with any one of the adjustment slots. Through the transmission of the planetary gear reduction mechanism, the rapid, large-angle rotation of the barrel is converted into the slow, small-angle rotation of the planetary carrier. It enables the rotation of the limiting protrusion or adjustment groove set on the planetary carrier to be more precise and controllable, making it easier for users to accurately align the limiting protrusion with the target adjustment groove.

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0019] like Figures 1 to 10As shown, the press pump of the present invention includes a pump body 1, a liquid dispensing pipe 2, a barrel 3, a planetary carrier 41, and a plurality of planetary gears 42. The pump body 1 has a mounting hole 11. The liquid dispensing pipe 2 includes a first mounting section 221, an external gear ring section 222, a second mounting section 223, and a third mounting section 211 arranged sequentially from top to bottom. The third mounting section 211 is slidably inserted into the mounting hole 11. The bottom of the barrel 3 is rotatably fitted onto the first mounting section 221. The barrel wall of the barrel 3 includes an internal gear ring section 31. The planetary carrier 41 is rotatably fitted onto the second mounting section 223. The plurality of planetary gears 42 are located on the barrel of the barrel 3. The planetary gear 42, planetary carrier 41, internal gear ring segment 31, and external gear ring segment 222 are rotatably connected to the planetary carrier 41. These planetary gears 42, planetary carrier 41, internal gear ring segment 31, and external gear ring segment 222 form a planetary gear 42 reduction mechanism. One of the planetary carrier 41 and pump body 1 is provided with multiple adjusting slots 12, another of which is connected to a limiting protrusion 411. Rotating the barrel 3 causes the planetary gear 42 reduction mechanism to drive the planetary carrier 41 to rotate, allowing the limiting protrusion 411 to be vertically aligned with any adjusting slot 12. Through the transmission of the planetary gear reduction mechanism, the rapid, large-angle rotation of the barrel 3 is converted into a slow, small-angle rotation of the planetary carrier 41. This allows for more precise and controllable rotation of the limiting protrusion 411 or adjusting slot 12 on the planetary carrier 41, making it easier for the user to accurately align the limiting protrusion 411 with the target adjusting slot 12. When the limiting protrusion 411 is opposite to the deeper adjustment groove 12, pressing down on the liquid extraction tube 2 will cause the liquid extraction tube 2 to move downward a greater distance, thereby resulting in a larger liquid extraction volume; when the limiting protrusion 411 is opposite to the shallower adjustment groove 12, pressing down on the liquid extraction tube 2 will cause the liquid extraction tube 2 to move downward a smaller distance, thereby resulting in a smaller liquid extraction volume.

[0020] In some embodiments, such as Figures 3 to 5 As shown, the planetary carrier 41 is a circular plate, with a limiting protrusion 411 at the lower end of the planetary carrier 41 and an adjusting groove 12 at the upper end of the pump body 1. The barrel wall of the barrel body 3 also includes a shielding section 32 connected to the lower end of the internal gear ring section 31. The planetary carrier 41 is set in the barrel cavity of the shielding section 32, and the outer periphery of the planetary carrier 41 slides in cooperation with the inner sidewall of the shielding section 32. This arrangement allows the planetary carrier 41 to form a protective cavity with the barrel body 3. The internal gear ring section 31, the external gear ring section 222, and multiple planetary gears 42 are all set in the protective cavity, providing a relatively enclosed space for the planetary gear 42 reduction mechanism and preventing the mating parts of the planetary gear 42 reduction mechanism from being worn due to impurities entering.

[0021] Specifically, such as Figure 3 , Figure 4As shown, each adjustment groove 12 is located on the upper end of the wall of the mounting hole 11, with the groove opening facing upwards. The depth direction of each adjustment groove 12 is vertical, and the adjustment grooves 12 are spaced apart around the axis of the mounting hole 11. A sealing ring 43 is fitted on the outer periphery of the planetary carrier 41, and the sealing ring 43 abuts against the inner side of the barrel wall of the shielding section 32. The sealing ring 43 is an elastic rubber ring. The outer periphery of the sealing ring 43 abuts against the inner side of the barrel wall of the shielding section 32, and the inner periphery of the sealing ring 43 abuts against the outer periphery of the planetary carrier 41. The sealing ring 43 seals the gap between the planetary carrier 41 and the barrel wall of the shielding section, improving the sealing performance of the space where the planetary gear 42 retrieval mechanism is located.

[0022] In some embodiments, the barrel 3 is a transparent barrel. Specifically, the barrel 3 is made of a transparent material, and the correspondence between the limiting protrusion 411 and the adjusting groove 12 can be visually observed through the barrel wall of the barrel 3, making it easy to determine the amount of liquid taken. The lower section of the barrel wall forms a shielding section, and the inner toothed ring section 31 is located above the shielding section. The inner side of the inner toothed ring section 31 has an inner toothed ring structure, and the outer side has anti-slip texture 311. Rotating the outer side of the inner toothed ring section 31 will rotate the barrel 3. The anti-slip texture 311 facilitates the rotation of the barrel 3, and the smooth outer side of the shielding section allows for clear observation of the correspondence between the adjusting groove 12 and the limiting protrusion 411.

[0023] In some embodiments, such as Figure 9 , Figure 10 As shown, there are two limiting protrusions 411, which are arranged symmetrically at the center. The center of symmetry of the two limiting protrusions 411 is located on the central axis of the liquid collection tube 2. The adjusting groove 12 includes multiple pairs of grooves arranged in pairs. The groove depth of the same pair of adjusting grooves 12 is the same. The two adjusting grooves 12 in the same pair are arranged symmetrically at the center. The center of symmetry of the same pair of adjusting grooves 12 is located on the central axis of the liquid collection tube 2. In this embodiment, the reason why two limiting protrusions 411 can be set is mainly because the limiting protrusions 411 are located at the lower end of the planetary carrier 41, and there are no other components to be installed at the lower end of the planetary carrier 41 except for the limiting protrusions 411. That is, the planetary carrier 41 can be installed at any position in the 360° circumference of the liquid collection tube 2. Setting two symmetrically arranged limiting protrusions 411 can improve the stress stability of the liquid collection tube 2 when it is pressed down, compared to setting only one limiting protrusion 411. Moreover, at least one limiting protrusion 411 can be observed through the barrel wall from either side, making it easy to observe the correspondence between the limiting protrusion 411 and the adjustment groove 12 when rotating the barrel 3.

[0024] In some embodiments, such as Figure 4As shown, the liquid collection tube 2 includes a tube body 21 and an outer sleeve 22. The outer sleeve 22 is fixedly sleeved on the upper outer side of the tube body 21. A first mounting section 221, an external gear ring section 222, and a second mounting section 223 are formed in the outer sleeve 22. A third mounting section 211 is formed at the lower part of the tube body 21. Specifically, the tube body 21 includes an upper tube section 213 and a lower tube section. The upper tube section 213 and the lower tube section are inserted into each other and fixed together by adhesive bonding. The lower tube section forms the third mounting section 211. The outer sleeve 22 is connected to the upper section pipe 213. The outer side of the upper section pipe 213 is provided with a protruding rib 2131 extending in the vertical direction. The inner wall of the outer sleeve 22 is provided with a limiting groove arranged in the vertical direction. After the outer sleeve 22 is fitted onto the upper section pipe 213 from bottom to top, the protruding rib 2131 slides into the limiting groove. Under the action of the protruding rib 2131 and the limiting groove, the outer sleeve 22 cannot rotate relative to the upper section pipe 213. The outer sleeve 22 is a stepped sleeve. The outer sleeve 22 is also connected to a first retaining ring 71 and a second retaining ring 72. The diameters of the first mounting section 221 and the second mounting section 223 are smaller than the diameter of the outer gear ring section 222. Before the outer sleeve 22 is fitted onto the upper tube body 213, the barrel body 3 needs to be fitted onto the outside of the first mounting section 221 from top to bottom, and the first retaining ring 71 is locked onto the first mounting section 221. The bottom of the barrel body 3 cannot move axially on the first mounting section 221 under the axial blocking action of the first retaining ring 71 and the outer gear ring section 222, but it can rotate around the axis of the first mounting section 221. Before fitting the outer sleeve 22 onto the upper tube body 213, the planetary carrier 41 needs to be fitted from bottom to top onto the outside of the second mounting section 223, and a second retaining spring 72 is engaged on the second mounting section 223. Under the axial blocking action of the second retaining spring 72 and the external gear ring section 222, the planetary carrier 41 cannot move axially on the second mounting section 223, but can rotate around the axis of the second mounting section 223. The first mounting section 221, the second mounting section 223, and the external gear ring section 222 are arranged coaxially. A third retaining spring 73 is also engaged at the lower part of the upper tube body 213. After fitting the outer sleeve 22, which contains the barrel body 3 and the planetary carrier 41, onto the upper tube body 213, the third retaining spring 73 is engaged on the lower outer side of the upper tube body 213, achieving axial blocking of the outer sleeve 22. Under the action of the third retaining spring 73, the outer sleeve 22 cannot rotate relative to the upper tube body 213. Under the action of the rib 2131, the limiting groove, and the third retaining spring 73, the outer sleeve 22 is fixed to the upper section tube 213. After the outer sleeve 22 is fitted onto the upper section tube 213, the planetary reduction gear mechanism is assembled. Then, the upper section tube 213 and the lower section tube are connected. The upper inner side of the lower section tube also has a limiting groove. The lower part of the upper section tube 213 is inserted into the cavity of the lower section tube. The rib 2131 engages with the limiting groove on the inner side of the lower section tube. The mating area between the upper section tube 213 and the lower section tube is filled with adhesive. The upper section tube 213 and the lower section tube are fixedly connected by adhesive.

[0025] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 As shown, the liquid dispensing tube 2 also includes a pressing part 212, which is connected to the upper end of the tube body 21. At least a portion of the pressing part 212 has a receiving space 5 between it and the barrel 3. The pressing pump also includes an elastic resistance-increasing element 6, which is disposed in the receiving space 5. The lower end of the elastic resistance-increasing element 6 abuts against the barrel 3, and the upper end of the elastic resistance-increasing element 6 abuts against the pressing part 212. After the position of the planetary carrier 41 is adjusted to the correct position, that is, after the limiting protrusion 411 is aligned vertically with the required adjustment groove 12, the barrel 3 will be subjected to rotational resistance under the action of the elastic resistance-increasing element 6, thereby enabling the barrel 3 to remain in the adjusted position. When the position of the planetary carrier 41 needs to be readjusted, the barrel 3 can be rotated by hand to overcome the resistance applied to the barrel 3 by the elastic resistance element 6 and rotated to a new position. Whether the barrel 3 is rotating or the barrel 3 is fixed, the elastic resistance element 6 will always apply rotational resistance to the barrel 3. After the barrel 3 is released by hand, the barrel 3 remains fixed under the action of this rotational resistance.

[0026] Furthermore, such as Figure 7 As shown, the elastic resistance-increasing element 6 is an elastic ring. The ring is fixed to the end of the barrel 3 facing the receiving space 5. A protrusion 2123 is fixed to the end of the pressing part 212 facing the receiving space 5, and the protrusion 2123 is pressed against a part of the ring. The distance between the lowest point of the protrusion 2123 and the bottom of the barrel 3 is less than the height of the elastic resistance-increasing element 6. The protrusion 2123 can apply pressure to a local part of the elastic resistance-increasing element 6, thereby causing a downward indentation at the position where the elastic resistance-increasing element 6 contacts the protrusion 2123. The downward indentation can increase the rotational resistance applied by the elastic resistance-increasing element 6 to the barrel 3.

[0027] Among them, such as Figure 6 As shown, the pressing part 212 includes a body part 2121 and a liquid outlet part 2122. The liquid outlet part 2122 has a liquid outlet hole communicating with the tube body 21. A portion of the liquid outlet part 2122 protrudes into the receiving space 5 to form a protrusion 2123. Specifically, the wall of the liquid outlet hole itself protrudes into the receiving space 5. The body part 2121 is disc-shaped and is coaxially arranged with the tube body 21. The axial direction of the liquid outlet hole extends radially along the body part 2121. The wall of the liquid outlet hole is used as the protrusion 2123 to facilitate the processing of the pressing part 212.

[0028] In some embodiments, such as Figure 3As shown, the mounting hole 11 includes a large hole section 112 and a small hole section 111. The small hole section 111 is located above the large hole section 112. Each limiting groove is provided on the hole wall of the small hole section 111. The third mounting section 211 includes a first section 2111, a second section 2112, and a third section 2113 arranged sequentially from top to bottom. The first section 2111 passes through the small hole section 111, and the second section 2112 and the third section 2113 are arranged in the large hole section 112. Moreover, the second section 2112... The outer sidewall has a first flange 21121, the upper end of which abuts against the lower end of the small hole section 111. A compression spring 74 is sleeved on the outer side of the third section 2113. The inner sidewall of the lower part of the large hole section 112 has a second flange 13 protruding into the mounting hole 11. The lower end of the compression spring 74 abuts against the second flange 13, and the upper end abuts against the first flange 21121. The compression spring 74 can apply an upward elastic force to the first flange 21121. A piston 75 is connected to the lower end of the third section 2113. The piston 75 is located in the liquid intake chamber 14 of the pump body 1. A first check valve that can be opened upward is provided at the center of the piston 75, and a second check valve that can be opened upward is provided at the lower end of the liquid intake chamber 14. Initially, there is no liquid in the dispensing chamber 14. After the user presses the pressing part 212, the upper tube 213 moves the lower tube downward, compressing the compression spring 74. This causes the lower tube to move the piston 75 downward, reducing the space in the dispensing chamber 14 and increasing the air pressure inside. The first one-way valve is opened by the air pressure, allowing air from the dispensing chamber 14 to enter the dispensing tube 2. After the user releases the pressing part 212, the compression spring 74 pushes the first flange 21121 upward, causing the dispensing tube 2 to move upward and reset, moving the piston 75 upward. At this time, a negative pressure appears in the dispensing chamber 14. Under the action of the negative pressure, the second one-way valve opens, allowing the liquid from the daily-use bottle to flow into the dispensing chamber 14. During subsequent use, pressing the pressing part 212 downward causes the liquid in the dispensing chamber 14 to open the first one-way valve and enter the dispensing tube 2. The greater the downward movement of the pressing part 212, the greater the amount of liquid dispensed in a single operation. Before use, users can adjust the liquid dispensing volume by rotating the operating section according to their usage habits or specific needs. For example, in places such as hotels and public places, setting a smaller single dispensing volume can avoid waste.

[0029] 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.

[0030] like Figure 11As shown, the present invention also provides a daily chemical product bottle, including the aforementioned press pump. Specifically, the pump body 1 has a nut structure 15, and the cosmetic bottle includes a bottle body 8 and the aforementioned press pump. The nut structure 15 is connected to the bottle mouth of the bottle body 8, thereby connecting the press pump to the bottle body 8.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
