Description

Technical Field

[0001] This utility model relates to the field of pumps, and in particular to a push pump with a sealing structure. Background Technology

[0002] Most everyday products such as shower gel, shampoo, and hand cream are packaged in bottles, and the liquid is drawn out and pumped out by a pump. These pumps can be divided into lotion pumps and foam pumps. To prevent accidental pressing during transportation or sales, existing pumps usually have a sealing mechanism. That is, the pump needs to be rotated at a certain angle before it pops out to be activated.

[0003] Meanwhile, to prove the product's authenticity, anti-counterfeiting mechanisms are incorporated. For example, Chinese invention patent 2007100461991 discloses a sealing device consisting of a tearing part and a fixing part. The tearing part comprises a ring and a first annular portion, while the fixing part comprises a second annular portion. When the pump head is rotated, the ring and the first annular portion rotate, causing the tear line between the first and second annular portions to break, thus providing excellent anti-counterfeiting protection. However, this anti-counterfeiting structure is easily damaged by accident. If the pump head is accidentally rotated, the tear line between the first and second annular portions may also break, compromising the product's anti-counterfeiting features and thus having certain limitations. Therefore, a press pump with a sealing structure is urgently needed to solve the above problems. Utility Model Content

[0010] As one of the preferred embodiments of this utility model, the welding strip is welded to the pump seat and pump head by ultrasonic welding process.

[0011] The beneficial effects of this utility model are as follows: A push-button pump with a sealing structure includes a pump base and a pump head. The pump head is rotatably mounted on the pump base and has a sealed state and an open state. The pump head can enter the sealed state when rotated in a first direction to approach the pump base, or enter the open state when rotated in a second direction to move away from the pump base. It also includes a welding strip with a pre-cut. When the pump head is in the sealed state, the upper end of the welding strip is welded to the pump head and the lower end is welded to the pump base. The welding strip can be broken along the pre-cut to separate the welding strip from the pump head and the pump base. The above structure not only enables the push-button pump to remain sealed before use, but also provides anti-counterfeiting function while preventing the pump head from being easily opened, which has very good practicality.

[0022] Reference Figures 1 to 5 A press pump with a sealing structure includes a pump base 10 and a pump head 20. The pump head 20 is rotatably mounted on the pump base 10 and has a sealed state and an open state. The pump head 20 can enter the sealed state when it is rotated in a first direction to be close to the pump base 10, or enter the open state when it is rotated in a second direction to be away from the pump base 10. The pump head 20 also includes a welding strip 30 with a pre-cut 31. When the pump head 20 is in the sealed state, the upper end of the welding strip 30 is welded to the pump head 20 and the lower end is welded to the pump base 10. The welding strip 30 can be broken along the pre-cut 31 to separate the welding strip 30 from the pump head 20 and the pump base 10.

[0023] In this invention, during production, the pump base 10 and pump head 20 are first assembled separately. Then, the pump head 20 is mounted on the pump base 10 and rotated in the first direction until it enters a sealed state. In the sealed state, the pump head 20 is positioned close to the pump base 10. The pump, now in the sealed state, is then placed into a welding fixture, and the welding strip 30 is prepared. The welding strip 30 is then welded to the upper and lower ends of the pump head 20 and to the pump base 10 using welding equipment. During use, the user cuts the welding strip 30 along the pre-cut 31 and then pulls the welding strip 30 outwards. At one end, the welding strip 30 breaks along the weld between itself and the pump base 10 and the pump head 20, thereby separating the welding strip 30 from the pump base 10 and the pump head 20. At this time, the pump head 20 can be rotated in the second direction to enter the open state. It should be noted that the connection between the welding strip 30 and the pump base 10 and the pump head 20 is a light connection, that is, the weld between the welding strip 30 and the pump base 10 and the pump head 20 is thin and long. When the welding strip 30 is torn, the weld between the welding strip 30 and the pump base 10 and the pump head 20 will detach, thereby separating the welding strip 30.

[0024] Reference Figure 1 , Figure 2 and Figure 5 In some embodiments, the welding strip 30 is provided with an ear 32 located on one side of the pre-cut 31. By providing the ear 32, it is convenient for the user to grasp the welding strip 30, and it is also convenient for the welding strip 30 to break along the pre-cut 31, thereby improving the convenience of operation.

[0025] Reference Figures 1-5 In some embodiments, the pump head 20 is provided with a first step 21, and the pump base 10 is provided with a second step 11. The upper end of the welding strip 30 is welded to the outer wall of the first step 21, and the lower end of the welding strip 30 is welded to the outer wall of the second step 11. During welding, the upper end of the welding strip 30 is attached to the outer wall of the first step 21, and the lower end is attached to the outer wall of the second step 11, and then welding is performed using welding equipment. This arrangement can improve the convenience of welding operation. In some embodiments, the first step 21 is integrally formed with the pump head 20, and the second step 11 is integrally formed with the pump base 10.

[0026] Reference Figures 1-5 In some embodiments, the pump base 10, pump head 20, and welding strip 30 are made of plastic. Furthermore, the welding strip 30 is welded to the pump base 10 and pump head 20 by an ultrasonic welding process.

[0027] The advantages of this invention are that the above structure not only keeps the pump sealed before use, but also prevents the pump head from being easily opened while providing anti-counterfeiting functions, making it very practical.

[0028] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
