Figure 1 In the figure, the foam dispenser 1 includes a rear cover 12 for mounting the foam dispenser 1 on a building wall 2, and the foam dispenser 1 also includes a first cover member 13 and a second cover member 14, which can be opened and closed to remove and install the liquid storage device 11. The foam dispenser 1 also includes a support plate 15, which extends forward from the rear cover 12, and includes a rear portion 151, two side arms 152 (only one of which is seen) and a front portion 153, the two side arms 152 connecting the rear portion 151 and the front portion 153, one end of the front portion 153 is hingedly connected to the first cover member 13, and the other end can rotate around a hinge point (not shown in the figure), and there is a predetermined distance between the front portion 153 and the two side arms 152, and the rear portion 151, the two side arms 152 and the front portion 153 enclose a second opening 154, through which the liquid storage device 11 can be inserted downward. The side wall of the rear portion 151 close to the front portion 153 has a groove 1511. The liquid storage device 11 is placed in the second opening 154 and moved backward to engage the liquid storage device 11 with the groove 1511. Figure 2The liquid storage device 11 includes a pump assembly 16, and the pump assembly 16 includes a piston forming part 161 and a piston cavity 162. After the liquid storage device 11 is placed in the second opening 154, the liquid storage device 11 is moved backward to clamp the piston cavity 162 in the groove 1511, thereby engaging the liquid storage device 11 in the groove 1511.
[0026] The piston forming member 161 is reciprocatingly slidable relative to the piston cavity 162, and the reciprocating sliding includes a retraction stroke from the extended position to the retracted position and an extension stroke from the retracted position to the extended position. Figure 1 , Figure 2 , Figure 6 and Figure 7 The piston forming part 161 presents an inverted "∏"-shaped structure, and the piston cavity 162 includes a first piston cavity 1621 and a second piston cavity 1622. The first piston cavity 1621 and the second piston cavity 1622 are respectively connected to the two arms of the piston forming part 161 presenting an inverted "∏"-shaped structure. It can be understood that the piston forming part 161, the first piston cavity 1621 and the second piston cavity 1622 surround and form a first opening 163. The foam dispenser 1 further includes a pressing member 17 and a connecting member 18. One end of the pressing member 17 is connected to the piston forming member 161 and passes through the first opening 163. The other end of the pressing member 17 is a pressing portion 171. The pressing portion 171 is fixedly connected to the front portion 153 through the connecting member 18. When the user's hand 620 presses the pressing portion 171, the pressing portion 171 drives the front portion 153 to rotate around a hinge point (not shown), and at the same time drives the piston forming member 161 to retract upward and extend downward relative to the piston cavity 162, as shown in FIG. Figure 6 As shown, the piston forming member 161 extends downward relative to the piston cavity 162, and as shown in Figure 7 As shown, the piston forming part 161 moves upwardly in contraction relative to the piston cavity 162 .
