Description

Technical Field

[0001] The utility model belongs to the technical field of lotion pumps, and in particular relates to a folding-type liquid-discharging lotion pump. Background Art

[0002] In daily life, people often use toiletries such as shampoo and shower gel. Such products are usually packaged in containers with a dispensing device. Preferably, a lotion pump is used as the dispensing device. By pressing the lotion pump, the product in the container can be easily delivered for the user to use.

[0003] For example, a lotion pump provided by the utility model embodiment of application number CN201620766731.1 belongs to the field of lotion pumps. The lotion pump includes a pump head and a catheter, wherein the pump head is movably connected to the catheter, and the inner surface of one end of the catheter is provided with a rotation area, and the rotation area is provided with a plurality of limit bars, and the arc between each two adjacent limit bars forms a preset angle, and the pump head is embedded in the rotation area and connected to the catheter. The lotion pump uses the limit bars provided on the catheter so that when the pump head and the catheter are connected and rotated, they can rotate relative to the catheter within a maximum rotation range of 30 degrees, so that the pump head can rotate to the angle required by the user.

[0004] The lotion pump cannot be closed when not in use, which can easily lead to accidental pressing, resulting in waste, and is also inconvenient to carry and use. Utility Model Content

[0012] A further implementation scheme of the utility model is that one port of the liquid passage is located at the upper end of the containing groove, and the other port is located in the pump head. One end of the liquid outlet passage is located at the upper end of the folding head close to the positioning column, and the other end is located at the lower end of the folding head.

[0013] A further implementation scheme of the utility model is that the outer side of the lower end of the folding head is a handle.

[0014] A further implementation scheme of the utility model is that positioning ribs are arranged circumferentially inside the inner sleeve, and the upper end of the pump chamber is clamped and fixed between the inner wall of the inner sleeve and the positioning ribs.

[0015] A further implementation scheme of the utility model is that ratchets are provided on the outer circumference of the inner sleeve and the inner circumference of the lower end of the pump head, and the pump head and the inner sleeve are threadedly connected and the pump head and the inner sleeve can only rotate in one direction through the ratchet cooperation.

[0016] A further embodiment of the utility model is that it also includes a cap, which is used to be screwed on the bottle mouth, the upper end of the pump chamber is plugged into the cap and the upper end of the pump chamber partially extends out from the upper end of the cap.

[0017] The beneficial effects of the utility model are:

[0018] The lotion pump is provided with a rotatable folding head on the pump head, and the folding head can be unfolded and stored in the folding head. A liquid passage that can be connected to the interior of the bottle and used to guide the liquid is provided in the pump head, and a liquid outlet is correspondingly provided in the folding head. When the folding head is stored in the pump head, the liquid outlet is not connected to the liquid passage, the liquid passage is blocked, and the liquid in the bottle cannot flow out, thereby avoiding misoperation. When the folding head is unfolded until the liquid passage is connected to the liquid outlet, the liquid in the bottle can be squeezed out. By adjusting the folding head to retract and unfold, waste caused by misoperation can be avoided, and the pump is convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model provides a folding type lotion pump for discharging liquid, comprising a pump chamber 1, an inner sleeve 2, a pump head 3, a folding head 4 and a cover cap 5.

[0029] The pump chamber 1 can extend into the bottle for guiding the liquid.

[0030] The inner sleeve 2 can be removably arranged on the top of the pump chamber 1 and is connected to the inside of the pump chamber 1. Specifically, positioning ribs 20 are arranged circumferentially inside the inner sleeve 2, and the upper end of the pump chamber 1 is clamped and fixed between the inner wall of the inner sleeve 2 and the positioning ribs 20. The pump chamber 1 and the inner sleeve 2 can be disassembled and assembled by plugging and unplugging.

[0031] The cover cap 5 is used to be screwed onto the bottle mouth, the upper end of the pump chamber 1 is plugged into the cover cap 5 and the upper end of the pump chamber 1 partially extends out from the upper end of the cover cap 5 .

[0032] The pump head 3 is detachably connected to the inner sleeve 2, and the pump head 3 and the inner sleeve 2 are communicated. Ratchets 21 are provided on the outer circumference of the inner sleeve 2 and the inner circumference of the lower end of the pump head 3, and the pump head 3 and the inner sleeve 2 are threadedly connected and cooperate with the ratchet 21 so that the pump head 3 and the inner sleeve 2 can only rotate in one direction. After the pump head 3 is connected to the inner sleeve 2 after being rotated clockwise, the ratchet 21 cooperates in place and cannot continue to rotate clockwise. When the pump head 3 is rotated counterclockwise, the ratchet 21 can be disengaged from each other, and the pump head 3 can be removed at this time.

[0033] In addition, the folding head 4 is rotatably connected to the pump head 3 and can be folded and accommodated in the pump head 3. A liquid outlet 40 is provided in the folding head 4. A liquid passage 30 is provided in the pump head 3 to connect the pump chamber 1 and the inner sleeve 2. Moreover, when the folding head 4 is accommodated in the pump head 3, the liquid passage 30 is blocked by the folding head 4. When the folding head 4 is folded open, the liquid passage 30 is connected to the liquid outlet 40.

[0034] In this embodiment, the folding head 4 is preferably rotatably arranged in one side of the pump head 3. More specifically, a receiving groove 31 for accommodating the folding head 4 is opened in one side of the pump head 3, and positioning grooves 32 are set on both sides of the upper end of the accommodating groove 31. A positioning column 41 is formed on the outer side of the upper end of the folding head 4, and the folding head 4 is rotatably connected to the accommodating groove 31 through the positioning column 41 and the positioning groove 32.

[0035] As mentioned above, one end of the liquid passage 30 is located at the upper end of the accommodating groove 31, and the other end is located in the pump head 3. One end of the liquid outlet 40 is located on the folding head 4, close to the upper end of the positioning column 41, and the other end is located at the lower end of the folding head 4. The outer side of the lower end of the folding head 4 is a handle 42, and the folding head 4 can be easily operated and unfolded through the handle 42. When the folding head 4 is stored in the pump head 3, the liquid outlet 40 is not connected with the liquid passage 30, the liquid passage 30 is blocked, and the liquid in the bottle cannot flow out, avoiding misoperation. When the folding head 4 is unfolded until the liquid passage 30 is connected to the liquid outlet 40, the liquid in the bottle can be squeezed out to the outside. Through the expansion and contraction adjustment of the folding head 4, waste caused by misoperation can be avoided, and it is also convenient to carry.

[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.
