[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0026] In view of the disadvantage that the existing lotion pump has a poor hand feel due to the imperfect design of the pressure head, the utility model provides a lotion pump with improved pressing feel to solve the technical problem.

[0027] like Figure 1 The lotion pump comprises: a pump chamber 1, an inner sleeve 2, an outer cover 3, a pump tube 4, a pump head 5 and a bottom tube 6.

[0028] Among them, soft rubber 50 is embedded in the upper part of the pump head 5. The soft rubber 50 is round and has a soft texture. It can be understood that the traditional pump head 5 is made of one-piece injection molding, and the palm feels consistent when pressed, and is relatively hard, resulting in an uncomfortable feel. The addition of the soft rubber 50 can effectively support the palm and provide a cushioning effect to the palm, thereby comprehensively improving the comfort of the hand when pressing.

[0029] The pump tube 4 can be elastically pressed and arranged in the inner sleeve 2. The pump tube 4 is connected to the inside of the inner sleeve 2. The upper end of the pump tube 4 is directly plugged and fixed in the pump head 5, and the pump tube 4 is also provided with a limit platform 40. When the pump tube 4 is inserted in the inner sleeve 2, a spring can be sleeved on the pump tube 4. The spring and the inner sleeve 2 are elastically abutted. When the pump tube 4 rises to a certain height, it abuts against the inner sleeve 2 through the limit platform 40 to stop moving. After the pump tube 4 moves downward, the internal pump liquid space is compressed so that the emulsion is pressed out of the pump head 5.

[0030] The outer cover 3 is hollow inside, the inner sleeve 2 is detachably plugged into the outer cover 3 and the inside is communicated with the outer cover 3, the pump chamber 1 is located at the lower part of the outer cover 3 and passes through the inside of the outer cover 3, the upper end of the pump chamber 1 is plugged into and matched with the inner sleeve 2, so that the inner sleeve 2 is communicated with the inside of the pump chamber 1.

[0031] like Figure 4In detail, a groove 30 is formed on the upper portion of the outer cover 3, and a thread is formed on the inner wall of the outer cover 3. The outer cover 3 is screwed onto the bottle mouth through the thread. A plurality of reinforcing ribs 31 are formed circumferentially inside the outer cover 3 to improve the overall structural strength of the outer cover 3 through the reinforcing ribs 31.

[0032] like Figure 3 The inner sleeve 2 has a central through structure. A ring platform 20 is formed on the inner sleeve 2. A shoulder 21 is formed on the upper part of the ring platform 20. The inner sleeve 2 is inserted into the groove 30 through the ring platform 20. The shoulder 21 overlaps the top surface of the outer cover 3. Therefore, the inner sleeve 2 is pressed from the outer cover 3 so that the ring platform 20 is inserted into the groove 30 and fixed until the shoulder 21 fits the upper end of the outer cover 3. When disassembling, the inner sleeve 2 can be directly pulled out by force. In addition, mutually matching threads are provided on the upper end of the inner sleeve 2 and the lower end of the pump head 5, so that the pump head 5 can be locked and fixed on the inner sleeve 2 after pressing the pump head 5 and rotating the pump head 5. It can well avoid accidental pressing when not in use for a long time or when being carried and transported.

[0033] As a further embodiment of the present invention, Figure 3 A plurality of positioning ribs 22 are arranged and formed on the inner sleeve 2 along its circumferential direction. The positioning ribs 22 are arranged opposite to the inner wall of the ring platform 20, and the positioning ribs 22 and the inner wall of the ring platform 20 are spaced apart. The positioning ribs 22 are used to play a role of fixed connection with the pump chamber 1. In addition, a positioning groove 23 is formed on the inner wall of the inner sleeve 2. The positioning groove 23 is an annular groove, which also plays a role of fixed connection with the pump chamber 1.

[0034] The pump chamber 1 is internally open, such as Figure 3 A convex rib 10 is formed on the outside of the upper end of the pump chamber 1, and the convex rib 10 and the positioning groove 23 are both arc-shaped surfaces. The upper end of the pump chamber 1 penetrates into the inner sleeve 2 and is fixed between the inner wall of the ring platform 20 and the positioning rib 22. The convex rib 10 and the positioning groove 23 are snap-fitted, that is, the inner sleeve 2 is directly pressed down from the upper end of the pump chamber 1, and the convex rib 10 is directly snapped into the positioning groove 23 for cooperation, and the upper end of the pump chamber 1 is just clamped between the positioning rib 22 and the inner wall of the ring platform 20 for fixation.

[0035] like Figure 3The bottom tube 6 is plugged into the lower end of the pump chamber 1. The bottom tube 6, pump chamber 1, inner sleeve 2, pump tube 4 and pump head 5 together form a pumping space. By pressing the pump head 5, the pump tube 4 moves downward to compress the pumping space, so that the lotion passes through the pump chamber 1, inner sleeve 2, and pump tube 4 and is pressed out of the pump head 5. After being released, the pump tube 4 automatically resets and rises to the limit table 40 against the inside of the inner sleeve 2 and then stops, and the external air is sucked in to provide conditions for the next pressing. It can be seen that the lotion pump improves the pump head 5 by embedding the soft rubber 50 on the pump head 5. While pressing, the soft texture of the soft rubber 50 itself provides a cushioning support for the palm, improving the comfort of pressing. By pressing the pump head 5, the pump tube 4 is pushed downward. After the pump liquid space formed by the pump tube 4 and the pump chamber 1 is compressed, the internal emulsion passes through the bottom tube 6, the pump chamber 1, the inner sleeve 2, and the pump tube 4 in turn and is finally pressed out from the pump head 5. When not in use for a long time, the pump head 5 can be pressed and then rotated to lock the pump head 5 and the inner sleeve 2 to prevent accidental pressing.

[0036] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
