An electric sprayer and its housing installation structure

Abstract

The invention discloses an electric mist sprayer and a shell mounting structure thereof. The electric mist sprayer is characterized by comprising an upper box body and a lower box body which is located below the upper box body, a storage cavity is formed inside the upper box body, the electric mist sprayer further comprises a connecting bolt, the lower box body comprises a left box body and a right box body, a left connecting pillar extends into the left box body, and a right connecting pillar extends into the right box body; a connecting sheet extends below the upper box body, a penetrating hole for the left connecting pillar and / or the right connecting pillar to penetrate through is formed in the connecting sheet, the connecting bolt penetrates through the left connecting pillar from theouter side of the lower box body, and the end of the connecting bolt is in threaded connection with the right connecting pillar. By means of the electric mist sprayer, the connecting structure of theupper box body, the left box body and the right box body is high in stability, and the detaching convenience is also high.

Description

technical field [0001] The invention relates to an electric sprayer, in particular to an electric sprayer and its casing installation structure. Background technique [0002] The structure of the traditional electric sprayer, such as a Chinese utility model with the notification number CN2354386Y, is a knapsack-type electric self-controlling pressure sprayer, which has a box-like shell, and the structure of the shell can refer to the attached figure 1 , there is a liquid storage chamber for liquid storage in the shell, a cavity is provided on the right side of the liquid storage chamber, and a battery, a pressure tank, etc. are installed in the cavity, and a mechanical pump chamber is also provided on the lower side of the liquid storage chamber. A pressure pump is installed in the pump cavity; this type of sprayer housing is integrally formed by injection molding, and the molds required for injection molding such housings are relatively complicated. [0003] In order to re...

[0002] The structure of the traditional electric sprayer, such as a Chinese utility model with the notification number CN2354386Y, is a knapsack-type electric self-controlling pressure sprayer, which has a box-like shell, and the structure of the shell can refer to the attached figure 1 , there is a liquid storage chamber for liquid storage in the shell, a cavity is provided on the right side of the liquid storage chamber, and a battery, a pressure tank, etc. are installed in the cavity, and a mechanical pump chamber is also provided on the lower side of the liquid storage chamber. A pressure pump is installed in the pump cavity; this type of sprayer shell is integrally formed by injection molding, and the mold required for injection molding such a shell is relatively complicated

[0003] In order to reduce the complexity of the injection mold, the housings of some sprayers are also split, that is, the original one-piece housing is divided into an upper housing and a lower housing, the liquid storage chamber is located in the upper housing, and the battery, pressure pump etc. will be installed on the lower surface of the upper case, the lower case will cover the lower surface of the upper case, and the lower case will cover the battery, pressure pump, etc., the contact point between the upper case and the lower case It is usually connected by vibration friction welding. During use, if the lower shell or the upper shell is damaged, the shell needs to be replaced as a whole, which is a serious waste of materials and is not conducive to environmental protection.
