Problems solved by technology

Existing spray caps used for spray pumps have a relatively complex structure and generally do not have a protective structure, which is prone to mispressing and causing unnecessary troubles
Moreover, due to the design defect of the existing spray cap, there is not enough space at the outlet to expand the content sprayed from the spray can, and it cannot form enough foam to meet the needs of users.

Abstract

The invention discloses a foam spraying cover with an insertion type protection structure. The foam spraying cover comprises a cover body, wherein a pressing head is arranged in the cover body; the foam spraying cover is characterized in that the pressing head comprises a pressing head seat; a liquid feeding channel is formed in the pressing head seat; a liquid spraying channel communicated with the liquid feeding channel is formed in the pressing head seat; a liquid outlet communicated with the liquid spraying channel is formed in the front end of the cover body; the insertion type protection structure capable of limiting the pressing head to move downwards is arranged between the rear end of the pressing head seat and the cover body. The invention provides the foam spraying cover which is simple in structure, safe and reliable and can produce foam in a jetting process in order to overcome the shortcomings in the prior art.

Description

technical field [0001] The invention relates to a foam spray cover with a plug-in protective structure. Background technique [0002] Due to its exquisite design and convenient use, the spray pump has been widely used in daily chemical and pharmaceutical industries. The existing spray caps used for spray pumps have a relatively complex structure, and generally do not have a protective structure, so it is easy to press them by mistake, causing unnecessary troubles. Moreover, the existing spray cap has insufficient space at the outlet to expand the content sprayed from the spray tank due to design defects, and cannot form enough foam to meet the needs of users. [0003] Therefore, the existing spray cover needs to be further improved. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies in the prior art and provide a foam spray cover with a plug-in protective structure that is simple in structure, safe and reliable, and cap...
