Description

Technical field:

[0001] The utility model relates to the technical field of perfume dispensing equipment, in particular to an improved automatic extraction device for perfume dispensing. Background technology:

[0002] Perfume is a common item in people's daily life. In order to prevent the volatilization of perfume, the perfume products currently sold on the market usually use a press pump nozzle at the bottle mouth. The press pump is driven downward by pressing the pressure head to pump out the perfume in the perfume bottle and then spray it out through the atomization port on the pressure head. Since perfume is expensive, in order to prevent counterfeit products, the general perfume nozzle is integrally formed with the perfume bottle body, which is difficult to separate, so it is impossible to directly pour the perfume in the perfume bottle into the sub-bottle.

[0003] At first, people chose to break the cap of the big bottle of perfume, open the nozzle of the sub-bottle, and then pour from the big bottle into the sub-bottle. This operation is troublesome and difficult to operate, and it is easy to cause the perfume to leak out and lose the top notes of the perfume;

[0004] Later, someone designed a special spray tube, replaced the nozzle of the large bottle, and then extended the tube into the sub-bottle, and pressed the large bottle again and again to spray the perfume into the sub-bottle. This method does not need to destroy the large bottle, but the sub-bottles produced by different manufacturers usually only correspond to one type of spray tube, which can only be used on the same manufacturer, the same model, and the same batch of perfumes. As a result, when users have multiple perfumes, they need to constantly change the sub-bottle, which not only increases the user's cost of use, but also generates a lot of resource waste.

[0005] The inventor has proposed a technical solution of "injection device for perfume sub-bottle", with patent publication number: CN215667074U; and subsequently proposed an invention patent application of "a perfume sub-bottle filling machine", with patent publication number: CN114408239A. These two technical solutions are to directly pump the perfume in the perfume bottle into the sub-bottle through a pump or an electric drive device. However, due to the use of electric drive, the entire device is large in size and requires a self-provided power supply or an external power supply, which is not convenient to carry.

[0006] In view of the above situation, the inventor has proposed a technical solution of "automatic extraction device for perfume dispensing", with patent announcement number CN220149199U, which includes: piston cylinder, piston and piston rod, the front end of the piston cylinder is formed with a liquid nozzle connected to the internal cavity, and the piston installed at the front end of the piston rod extends into the cavity of the piston cylinder; the piston rod is sleeved with a compression spring, and the front and rear ends of the compression spring act directly or indirectly between the piston cylinder and the piston rod respectively; the thrust generated by the compression spring on the piston rod drives the piston to have a tendency to move away from the liquid nozzle. In simple terms, it is to use the principle of the syringe and the elastic force of the compression spring to complete the extraction work. The user only needs to press the piston rod and use the elastic force of the compression spring to complete the extraction work.

[0007] However, this existing automatic extraction device for perfume dispensing has the following shortcomings due to its own structural design characteristics: this existing automatic extraction device is not integrated, and needs to be equipped with an adapter when used. Since the adapter is relatively small, it is very easy to lose. If it is lost, the extraction work cannot be completed, which often brings inconvenience. In addition, when using it, the automatic extraction device, the adapter and the external large perfume bottle need to be connected to each other at the same time to extract, which is not convenient enough. In addition, it is unstable when docking with the external large perfume bottle. Since it is necessary to control the alignment and connection of the adapter with the channel of the external large perfume bottle, it is easy to shake in the left and right directions, which is difficult to operate and is not friendly to novice users. Female consumers usually account for a larger proportion of perfume consumers, and female consumers will find it relatively difficult to use. Therefore, this solution needs to be improved urgently.

[0008] In view of this, the inventor proposes the following technical solution. Utility model content:

[0009] The utility model aims to overcome the shortcomings of the prior art and provide an improved automatic extraction device for perfume packaging.

[0010] In order to solve the above technical problems, the utility model adopts the following technical solutions: an improved automatic extraction device for perfume dispensing, comprising: a piston cylinder, a piston rod inserted in the piston cylinder and capable of being pulled back and forth, and a first piston installed at the front end of the piston rod, a first compression spring is sleeved on the piston rod, and the front and rear ends of the first compression spring respectively act directly or indirectly between the piston cylinder and the piston rod, a one-way sealing device capable of being conducted to the outside is arranged at the liquid nozzle at the front end of the piston cylinder, and the first compression spring generates a thrust on the piston rod to drive the first piston to have a tendency to move away from the one-way sealing device; the one-way sealing device comprises: a sleeve connected to the piston cylinder, a second piston arranged in the sleeve, a second compression spring, and a sealing sleeve installed in the second piston to achieve one-way sealing.

[0011] Furthermore, in the above technical solution, a needle tube that can pass through the sealing sleeve is arranged in the liquid nozzle formed at the front end of the piston cylinder; the front and rear ends of the second compression spring respectively act directly or indirectly between the piston cylinder and the second piston, and the second compression spring generates a thrust on the second piston to drive the sealing sleeve to have a tendency to move away from the needle tube, so that the sealing sleeve is in a closed state.

[0012] Furthermore, in the above technical solution, the piston cylinder is formed with a connecting portion around the liquid nozzle, and an accommodating gap is formed between the connecting portion and the liquid nozzle, and the second compression spring is sleeved on the liquid nozzle and located in the accommodating gap; the shaft sleeve is fixedly connected to the connecting portion.

[0013] Furthermore, in the above technical solution, a one-way channel capable of communicating the liquid nozzle with the outside is opened in the sealing sleeve, and when the second compression spring is in a compressed state, the needle tube passes through the one-way channel, and the external perfume enters the piston cylinder through the needle tube.

[0014] Furthermore, in the above technical solution, the one-way channel includes a fixed section and an opening and closing section.

[0015] Furthermore, in the above technical solution, a liquid inlet hole communicating with the one-way channel is provided at the end of the second piston.

[0016] Furthermore, in the above technical solution, a bushing is fixed in the piston cylinder, and the piston rod is connected to the first piston after passing through the bushing; the front end of the first compression spring is pressed against the bushing; the space between the bushing and the liquid nozzle in the piston cylinder constitutes the compression space of the piston; a pressing piece is also provided at the rear end of the piston rod, and the pressing piece is formed with a pressing portion for pressing, and the pressing piece is also formed with a guide tube inserted into the bushing.

[0017] Furthermore, in the above technical solution, a convex portion is formed at the rear end of the bushing, and the convex portion abuts against the edge of the opening of the piston cylinder to seal the gap between the piston cylinder and the bushing.

[0018] Furthermore, in the above technical solution, the cross-sectional shape of the piston cylinder is triangular, and correspondingly, the cross-sectional shapes of the first piston and the bushing are also triangular.

[0019] Furthermore, in the above technical solution, the first piston has two airtight flanges protruding outward from its periphery, and the airtight flanges are in compression contact with the inner wall of the piston cylinder to form a sealed state in the compression space.

[0020] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: in terms of structural implementation, the utility model eliminates the adapter in the prior art by adding a one-way sealing device at the front end of the piston cylinder, thereby achieving integration and avoiding the problem of loss of the adapter. At the same time, the improved one-way sealing device can be extracted after only one docking, and further optimization is achieved in structure. In addition, after eliminating the adapter, the sleeve in the one-way sealing device can axially limit the second piston, making the one-way sealing device more stable when docking with the external large perfume bottle, and almost no left and right shaking. Novices can also use it easily for the first time, meeting the usage needs of female consumers. It is a better technical solution, can output better products to the market, and is more competitive in the market. Description of the drawings:

[0028] The utility model is further described below in conjunction with specific embodiments and drawings.

[0029] See Figures 1 to 7 As shown, an improved automatic extraction device for perfume dispensing includes a piston cylinder 10, a piston rod 11 inserted in the piston cylinder 10 and capable of being pulled back and forth, and a first piston 20 installed at the front end of the piston rod 11. The first piston 20 extends into the cavity of the piston cylinder 10 along with the piston rod 11.

[0030] A first compression spring 40 is sleeved on the piston rod 11, and the front and rear ends of the first compression spring 40 directly or indirectly act between the piston cylinder 10 and the piston rod 11; the first compression spring 40 is suitable for generating a thrust on the piston rod 11 to drive the first piston 20 to have a tendency to move away from the one-way sealing device 30.

[0031] Specifically, a bushing 50 is fixed in the piston cylinder 10, and the piston rod 11 is connected to the first piston 20 after passing through the bushing 50; the front end of the first compression spring 40 presses against the bushing 50; the space between the bushing 50 and the liquid nozzle 120 in the piston cylinder 10 constitutes a compression space 70 of the first piston 20; a pressing piece 60 is also provided at the rear end of the piston rod 11, and the pressing piece 60 is formed with a pressing portion 61 for pressing, and the pressing piece 60 is also formed with a guide tube 62 inserted into the bushing 50.

[0032] A convex portion 51 is formed at the rear end of the bushing 50 , and the convex portion 51 abuts against the edge of the opening of the piston cylinder 10 to seal the gap between the piston cylinder 10 and the bushing 50 .

[0033] The first piston 20 also has two airtight flanges 80 protruding outwardly from its periphery. The airtight flanges 80 are in compression contact with the inner wall of the piston cylinder 10 to form a sealed state in the compression space 70 .

[0034] The front end of the piston cylinder 10 is formed with a liquid nozzle 120, which is connected to the compression space 70 in the piston cylinder 10, thereby forming an automatically resettable syringe structure. The pressing member 60 is pushed, and the first piston 20 moves downward along the piston cylinder 10 through the cooperation of the conduction 62 and the bushing 50, and the air or perfume in the compression space 70 can be discharged through the liquid nozzle 120. When the pressure acting on the pressing member 60 disappears, the first piston 20 moves upward along the piston cylinder 10 through the elastic action of the first compression spring 40, and the compression space 70 forms a negative pressure, thereby sucking in external air or perfume through the liquid nozzle 120.

[0035] The improvement of the utility model over the prior art is that: the front end of the piston cylinder 10 is provided with a one-way sealing device 30 that can conduct the internal cavity and the outside, and a needle tube 140 is provided in the liquid nozzle 120. Among them, the needle tube 140 is fixed in the liquid nozzle 120, the front end opening of the needle tube 140 is inclined, and the front end of the needle tube 140 extends into the sealing sleeve 321. In the prior art, the liquid nozzle 120 is directly connected to the perfume bottle to achieve the extraction of perfume. Such extraction effect is not ideal, because it requires a docking device (such as a docking head) to be set between the liquid nozzle 120 and the nozzle of the perfume bottle, which will lead to unstable docking, and it is easy to form perfume leakage at the docking position. Even when the docking is not good, the top notes of the perfume will be lost, affecting the use effect. After feedback from users and a large number of tests, it is found that the improved solution of the utility model adds a one-way sealing device 30 and a needle tube 140 that cooperates with the one-way sealing device 30, and the extraction and injection of perfume are achieved through the needle tube 140.

[0036] Specifically, the one-way sealing device 30 includes: a sleeve 310 fixedly connected to the piston cylinder 10, a second piston 320 disposed in the sleeve 310, a second compression spring 322, and a sealing sleeve 321 embedded in the second piston 320 and capable of opening and closing.

[0037] In this embodiment, the one-way sealing device 30 is installed in the following manner: the piston cylinder 10 is formed with a connecting portion 130 around the liquid nozzle 120, and an accommodation gap is formed between the connecting portion 130 and the liquid nozzle 120. The second compression spring 322 is sleeved on the liquid nozzle 120 and is located in the accommodation gap.

[0038] The shaft sleeve 310 and the second piston 320 are pivotally connected with each other in a shaft hole, and the second piston 320 is provided with a liquid inlet hole 340 communicating with the one-way channel 330, and a gap is left between the second piston 320 and the connecting portion 130. The gap is used to enable the second piston 320 to move to the rear end when pressed.

[0039] At least one first buckle edge 131 is formed on the connection part 130, and at least one second buckle edge 312 is formed on the inner wall of the sleeve 310. The second buckle edge 312 is buckled on the first buckle edge 131 so that the sleeve 310 is fixedly connected to the connection part 130. A one-way channel 330 capable of conducting the liquid nozzle 120 and the outside is opened in the sealing sleeve 321. The needle tube 140 extends into the one-way channel 330. The front and rear ends of the second compression spring 322 act directly or indirectly between the piston cylinder 10 and the sealing sleeve 321. The second compression spring 322 is suitable for generating a thrust on the second piston 320 to drive the sealing sleeve 321 to have a tendency to move away from the needle tube 140, so that the sealing sleeve 321 is in a closed state. The one-way channel 330 includes a fixed section 331 and an opening and closing section 332, wherein the fixed section 331 is made of a hard material, and the opening and closing section 332 is made of a soft colloid. The one-way channel 330 includes a fixed section 331 and an opening and closing section 332. An opening and closing hole 333 is formed at the front end of the opening and closing section 332. When the second piston 320 is pressed and moves toward the liquid nozzle 120, the front end of the liquid nozzle 120 enters the one-way channel 330, and the sealing sleeve 321 also moves toward the liquid nozzle 120. Further, the needle tube 140 passes through the opening and closing section 332 and protrudes from the opening and closing hole 333 to conduct the external large perfume bottle and the piston cylinder 10.

[0040] In one embodiment of the present invention, see Figure 7As shown, the utility model is also provided with an upper cover 90 and a lower cover 100, wherein the upper cover 90 is provided on the pressing member 60 and is buckled with the piston cylinder 10, and the lower cover 100 is provided on the one-way sealing device 30 and is buckled with the piston cylinder 10. Specifically, the front end of the piston cylinder 10 is formed with a first stepped groove 13, and the first stepped groove 13 is also formed with a first groove 14, and the lower cover 100 is formed with a first convex portion 101, and the first convex portion 101 is buckled and fixed with the first groove 14; the rear end of the piston cylinder 10 is formed with a second stepped groove 16, and the second stepped groove 16 is also formed with a second groove 17, and the upper cover 90 is formed with a second convex portion 92, and the second convex portion 92 is buckled and fixed with the second groove 17.

[0041] The cross-sectional shape of the piston cylinder 10 is triangular, and correspondingly, the cross-sectional shapes of the first piston 20 and the bushing 50 are also triangular. The piston cylinder 10 has at least one side provided with a corrugated groove 18 for increasing friction and facilitating gripping.

[0042] In summary, in terms of structural implementation, the utility model adds a one-way sealing device 30 at the front end of the piston cylinder 10, thereby eliminating the adapter in the prior art, achieving integration, and avoiding the problem of loss of the adapter. At the same time, the improved one-way sealing device 30 can be extracted after only one docking, and further optimization is achieved in structure. In addition, after eliminating the adapter, the sleeve 310 in the one-way sealing device 30 can axially limit the second piston 320, so that the one-way sealing device 30 is more stable when docked with the external large perfume bottle, and there is almost no shaking in the left and right directions. Novices can also use it easily for the first time, which meets the usage needs of female consumers. It is a better technical solution, can output better products to the market, and is more competitive in the market.

[0043] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
