Host and electronic vaporization device

Abstract

A host for use in combination with a vaporizer includes: a housing assembly; a protective cover; a first drive part; and a second drive part. The first drive part is rotatably connected to the housing assembly and drives the second drive part to slide relative to the housing assembly. The housing assembly includes an opening. The second drive part is engaged with the first drive part and carries the vaporizer. Upon the first drive part driving the protective cover to open or close the opening, the second drive part drives the vaporizer to extend out of the housing assembly or retract within the housing assembly through the opening.

What is claimed is: 
     
         1 . A host for use in combination with a vaporizer, the host comprising:
 a housing assembly;   a protective cover;   a first drive part; and   a second drive part,   wherein the first drive part is rotatably connected to the housing assembly and is configured to drive the second drive part to slide relative to the housing assembly, the housing assembly comprises an opening, and the second drive part is engaged with the first drive part and is configured to carry the vaporizer, and   wherein, upon the first drive part driving the protective cover to open or close the opening, the second drive part is configured to drive the vaporizer to extend out of the housing assembly or retract within the housing assembly through the opening.   
     
     
         2 . The host of  claim 1 , wherein the first drive part comprises a sleeve provided with a helical groove on an inner wall surface of the host, and an outer wall surface of the second drive part comprises a helical protrusion engaged with the helical groove. 
     
     
         3 . The host of  claim 2 , wherein the outer wall surface comprises a first unit surface, the first unit surface occupies an angle of less than 360° on a circumference of the second drive part, and the helical protrusion is located on the first unit surface. 
     
     
         4 . The host of  claim 2 , wherein the sleeve comprises a body portion and a convex ring portion, the convex ring portion being connected to an outer side surface of the body portion and protruding relative to the outer side surface, and
 wherein the housing assembly comprises an upper housing and a lower housing, the opening is located at the upper housing, and the upper housing and the lower housing are disposed on the body portion and respectively abut against two opposite ends of the convex ring portion.   
     
     
         5 . The host of  claim 2 , further comprising:
 a mounting plate;   a cam; and   a transmission assembly,   wherein the mounting plate is located within the housing assembly and provided with a through hole corresponding to the opening,   wherein the sleeve comprises a sinking groove on an end surface facing the mounting plate,   wherein the cam is rotatably connected to the mounting plate, and   wherein, upon the sleeve rotating and sliding the cam into or out of the sinking groove to abut against the end surface, the cam is configured to drive the protective cover to close or open the through hole through the transmission assembly.   
     
     
         6 . The host of  claim 5 , wherein the transmission assembly comprises:
 a transmission part;   a first spring; and   a second spring,   wherein the first spring is connected between the transmission part and the mounting plate,   wherein the second spring is connected between the protective cover and the mounting plate, and   wherein the transmission part is slidably disposed on the mounting plate and is configured to press against the cam and the protective cover simultaneously.   
     
     
         7 . The host of  claim 6 , wherein the transmission part comprises a slot,
 wherein the protective cover comprises a covering portion, a rotating portion, and a pressing portion,   wherein the rotating portion is rotatably disposed on the mounting plate and connected between the covering portion and the pressing portion,   wherein the second spring is connected to the covering portion, and   wherein the pressing portion matches the slot.   
     
     
         8 . The host of  claim 6 , wherein the transmission part comprises a first slop, the cam comprises a second slop configured to press against the first slop, and the first slop inclines by a set angle relative to an axial direction of the sleeve. 
     
     
         9 . The host of  claim 6 , wherein the sleeve comprises a first plane and a first arc surface that define a boundary of the sinking groove,
 wherein the cam comprises a second plane and a second arc surface,   wherein the first plane extends along an axial direction of the sleeve and is configured to press against the second plane, and   wherein the first arc surface is slidable along the second arc surface.   
     
     
         10 . The host of  claim 1 , comprising at least one of:
 wherein the first driving part comprises a limiting groove, the housing assembly comprises a limiting bump, and the limiting bump matches the limiting groove upon the protective cover opening the opening,   wherein the housing assembly comprises a bracket at least partially accommodated in the first drive part, the bracket comprises a chute, the chute comprises a positioning hole, the second drive part comprises a guide portion and a positioning boss disposed on the guide portion, the guide portion slidably matches the chute, and the positioning boss is configured to match the positioning hole to define an ultimate sliding position of the second drive part,   wherein the host further comprises a flexible circuit board and a motherboard located in the housing assembly, one end of the flexible circuit board being electrically connected to the motherboard, and an other end of the flexible circuit board being configured to be electrically connected to the vaporizer.   
     
     
         11 . An electronic vaporization device, comprising:
 a vaporizer; and   the host of  claim 1 ,   wherein the vaporizer is detachably connected to the second drive part.
