[0067] The present invention will be further described below in conjunction with the accompanying drawings.

[0068] Example 1

[0069] like Figure 1 , Figure 7-10 The water storage and water delivery device 100 shown in FIG. 1 includes Figure 2The water tank 101 shown in the figure has a sliding plug 102 inside the water tank. The sliding plug 102 separates the inner cavity of the water tank into a water storage chamber 103 and an energy storage chamber 104. The water storage chamber 103 has a drain port 105 and a closable water inlet 106. The water inlet 106 is closed by a cover 119. The energy storage chamber 104 is provided with an energy storage spring 107. The energy storage spring 107 applies an elastic force to the sliding plug to cause the sliding plug to move toward one side of the water storage chamber. The sliding plug 102 is connected to a water adding operation part 108 located outside the water tank and used to move the sliding plug toward one side of the energy storage chamber. Therefore, under normal conditions, the energy storage spring 107 applies an elastic force to the sliding plug to cause the sliding plug to move toward one side of the water storage chamber, causing the water storage chamber to shrink, thereby transporting the water stored in the water storage tank outward. When the water in the water storage chamber is completely drained, the water adding operation part can overcome the elastic force of the energy storage spring and cause the sliding plug to move toward one side of the energy storage chamber, thereby expanding the water storage chamber and adding water from the water inlet. In order to seal the sliding plug and the box, a sealing ring 120 is arranged on the sliding plug.

[0070] Specifically, the water tank 101 is composed of a cylindrical box body 109 and a front cover 110 and a rear cover 111 arranged at both ends of the box body. A water storage chamber is formed between the front cover and the sliding plug, and an energy storage chamber is formed between the rear cover and the sliding plug. The energy storage spring 107 is a spiral compression spring supported on the sliding plug 102 and the rear cover 111 at both ends. In specific implementation, 1-8 spiral compression springs can be selected according to demand. Moreover, the sliding plug is connected to the water adding operation part through a pull rod 112 passing through the rear cover, so the energy storage chamber is open. The front cover is assembled at the front end of the box body, and the rear cover is made into one piece with the box body. The water adding operation part 108 is cylindrical and is sleeved on the rear end of the water tank to shield the rear end of the water tank.

[0071] like Figure 3 As shown, in order to keep the volume of the water storage chamber unchanged when adding water, that is, to prevent the sliding plug from moving, the sliding plug is equipped with a locking mechanism and an unlocking mechanism. The locking mechanism positions the sliding plug to prevent the sliding plug from moving with the elastic force of the energy storage spring, and the unlocking mechanism is used to release the positioning of the sliding plug by the positioning structure so that the sliding plug can move to transport water outward. Furthermore, the sliding plug can be positioned by the locking mechanism when not in use, thereby preventing the water storage chamber from being under a large pressure all the time, greatly reducing the requirements for its sealing structure, and thus increasing the service life of the product.

[0072] Specifically, the locking mechanism includes a locking rod 113 and a positioning groove 114 that moves with the sliding plug. The locking rod is inserted into the positioning groove 114 by the elastic force of a spring 115 to position the sliding plug. The unlocking mechanism includes an unlocking rod 117 with a force-applying portion 116 and a force-bearing portion 118 provided on the locking rod. The unlocking rod 117 is operated to make the force-applying portion 116 act on the force-bearing portion to force the locking rod out of the positioning groove to release the positioning of the sliding plug by the positioning structure.

[0073] Furthermore, a positioning groove 114 is provided on the slide plug 102. In the figure, the pull rod and the slide plug are made as one body, the positioning groove is provided on the pull rod, the locking rod 113 is perpendicular to the moving direction of the slide plug 102, the unlocking rod 117 is consistent with the moving direction of the slide plug 102, and the force-applying portion 116 is in the shape of an inclined surface. When the unlocking rod is moved along the moving direction of the slide plug, the inclined force-applying portion 116 acts on the force-bearing portion 118 to force the locking rod to move in a direction perpendicular to the moving direction of the slide plug to disengage from the positioning groove.

[0074] like Figure 6-10 The steam brush shown in the figure comprises a housing 200, a steam generator 300 disposed in the housing, and a steam outlet 400 connected to the steam generator. The housing 200 comprises a head 201 and a handle 202 intersecting with each other. The head extends forward and backward, and the handle extends downward. A water storage and water delivery device is mounted on the head or the handle. The steam brush also comprises Figure 1 The water storage and water delivery device 100 shown is arranged at the rear end of the head, and the water outlet is connected to the steam generator through a normally closed water valve 500. The normally closed water valve is used to block the water supply from the water storage chamber to the steam generator. The normally closed water valve has a valve opening operating part 501. The normally closed water valve can be opened in time (such as when steam needs to be generated for ironing) through the valve opening operating part 501 to allow the water stored in the water storage chamber to be delivered to the steam generator.

[0075] In specific implementation, the water storage and water delivery device can be fixed on the shell, and the drain outlet can be connected to the normally closed water valve through a water pipe; the water storage and water delivery device can also be detachably installed on the shell so as to be removed for water filling. At this time, the drain outlet can be shared with the water filling port, and a water valve can be configured. With the help of the water valve, when the water storage and water delivery device is installed on the shell, the water valve is opened and the water tank is connected to the normally closed water valve. When the water storage and water delivery device is removed, the water valve is closed.

[0076] like Figure 4-5 As shown, the normally closed water valve includes a valve body 502 and a valve plug 503. The valve body 502 has a water inlet 504, a water outlet 505 and a valve port 506 located between the water inlet and the water outlet. The valve plug is located in the valve body and closes the valve port 506 with the elastic force of a spring 509. The valve plug 503 extends an extension section 507 that cooperates with the valve opening operating part out of the valve body. The valve opening operating part is operated to cause the valve plug to move and open the valve port. The valve plug 503 is in the shape of a rod, and the valve opening operating part 501 is a telescopic rod. The telescopic rod is provided with an inclined surface 508 that contacts the end of the extension section. One end of the telescopic rod is located outside the housing for easy operation, such as Figure 6-10 As shown, one end of the telescopic rod is located at the outer gripping portion of the housing, so when in use, the user can hold the steam brush with his hand and press the telescopic rod with his fingers to move the telescopic rod to open the valve port. For sealing, a sealing ring is provided on the valve plug and its extension section.

[0077] Moreover, the unlocking rod 117 and the telescopic rod are the same rod, so that the structure is simple and the action is coordinated.

[0078] like Figure 7 As shown, when the water tank is initially short of water, the slide plug 102 is located at the far left, where it can be positioned by the step in the water tank. At this time, the lock rod 113 is snapped into the positioning groove 114 by the elastic force of the spring 115 to position the slide plug; Figure 8 As shown, the water inlet 106 of the water tank is opened, and the water adding operation part 108 is pulled rightward by hand, forcing the locking rod 113 to disengage from the positioning groove 114. The sliding plug 102 moves rightward to expand the water storage cavity, so that water can be added to the water storage cavity. After water is added, the water inlet is closed; the maximum water storage capacity of the water storage cavity is as shown in FIG. Fig. 9 As shown, at this time, the sliding plug is also positioned by the step in the water tank; Fig.10 , Figure 3 As shown, when working, the unlocking rod 117 (telescopic rod) is pressed with a finger, and the unlocking rod 117 (telescopic rod) moves to the right, and at the same time, the force-applying part 116 acts on the force-bearing part 118 on the lock rod, and the inclined surface 508 of the telescopic rod acts on the end of the rod-shaped valve plug extension section 507, and the lock rod 113 moves downward to exit the positioning groove 114, and the sliding plug 102 moves to the left, and the water tank outputs water outward, and the valve plug 503 moves upward to open the valve port 506, and the water flow can be delivered to the steam generator 300, and the steam is converted into steam by the steam generator and ejected from the steam outlet 400. Release the unlocking rod 117 (telescopic rod), the lock rod 113 and the valve plug 503 are reset, the normally closed water valve is closed, the sliding plug is positioned, and no water is delivered.

[0079] Example 2

[0080] like Fig.11 The figure shows a schematic diagram of the appearance of a steam brush. The steam brush comprises a housing 200, a steam generator (not shown) disposed in the housing, and a steam outlet connected to the steam generator. The housing 200 comprises a head 201 and a handle 202 intersecting with each other. The head extends forward and backward, and the handle extends downward. Figure 1 , Figure 13-17 The water storage and water delivery device of any structure can be installed on the head or on the handle. The handle is equipped with a steam switch 203, which serves as the force-applying part of the unlocking mechanism. When the steam switch is pressed, the unlocking mechanism releases the relative positioning of the sliding plug and the water tank by the locking mechanism. When the steam switch is released, the locking mechanism positions the sliding plug and the water tank relatively to prevent the sliding plug and the water tank from moving relative to each other with the help of elastic force to reduce the volume of the water storage chamber. In other words, when steam needs to be generated for work, the steam switch is pressed, and the volume of the water storage chamber will be reduced to transport the stored water to the steam generator. When steam does not need to be generated, the steam button is released, and the locking mechanism positions the sliding plug and the water tank relatively to prevent the sliding plug and the water tank from moving relative to each other with the help of elastic force to reduce the volume of the water storage chamber, and the water storage chamber will not transport water outward.

[0081] Fig.11In the embodiment, the water adding operation part of the water storage and water delivery device is a rod 121 extending from the sliding plug and exposed outside the handle. Pulling the rod outward to make the sliding plug and the water tank move relative to each other can expand the volume of the water storage chamber, and water can be added to the water storage chamber through the water adding port. The rod can be a part of the sliding plug or a component assembled on the sliding plug.

[0082] Example 3

[0083] Fig.12 Schematic diagram of water supply of the steam brush of Example 3; Fig.13 The water storage and water delivery device shown delivers water to the steam generator 300 through the one-way valve 600. The one-way valve 600 controls the water flow from the drain outlet to the steam generator, which can stabilize the water flow and prevent the steam or hot water generated by the steam generator from flowing back during operation.

[0084] Fig.13 The water storage and water delivery device shown. Its locking mechanism includes a friction block 122 and a friction surface 123 that moves with the sliding plug. A lever 124 is installed on the handle like a lever. An elastic element 125 acts on one end of the lever to make the other end of the lever approach the friction surface. The friction block 122 is installed on the other end of the lever 124. With the help of the elastic force of the elastic element 125, the friction block is contacted on the friction surface to position the sliding plug. In particular, the friction block is eccentrically contacted on the friction surface as shown in the figure, so that the friction block can be prevented from slipping relative to the friction surface. Moreover, when the friction block contacts the friction surface to position the sliding plug, the sliding plug can be pulled downward to increase the volume of the water storage chamber, which is conducive to adding water to the water storage chamber. The friction surface and the friction block are preferably made of a material with a large friction coefficient, such as rubber, leather, etc.

[0085] The unlocking mechanism includes a force-applying part which is a steam switch 203 provided on the handle. When the force-applying part is pressed, the force-applying part transmits force to the tilting rod, and the tilting rod tilts to make the friction block leave the friction surface, and the sliding plug can move under the tension of the spiral tension spring 126 to reduce the water storage chamber and transmit water outward. The two ends of the spiral tension spring are respectively connected to the sliding plug and the water tank. In this embodiment, the function of the spiral tension spring can be realized by a spiral compression spring, that is, the spiral compression spring is placed on the other side of the sliding plug to apply thrust to the sliding plug.

[0086] Example 4

[0087] Fig.14Another water storage and water delivery device is shown. The locking mechanism of the water storage and water delivery device includes a positioning tooth 127 and a tooth groove 128 that moves with the sliding plug. The tooth groove 128 is provided on the rod 121. A lever is assembled on the handle like a lever. An elastic element acts on one end of the lever to make the other end of the lever approach the tooth groove. The positioning tooth is assembled on the other end of the lever. With the help of the elastic force of the elastic element, the positioning tooth is engaged in the tooth groove to position the sliding plug. In particular, the positioning tooth is eccentrically engaged in the tooth groove as shown in the figure, so that one-way positioning can be achieved, that is, when the positioning tooth is engaged in the tooth groove to position the sliding plug, the sliding plug is prevented from moving in the direction of reducing the water storage chamber, and the sliding plug can be pulled downward to expand the water storage chamber to add water to the water storage chamber.

[0088] The unlocking mechanism also includes a force-applying part which is a steam switch provided on the handle. When the force-applying part is pressed, the force-applying part transmits force to the tilting rod, and the tilting rod tilts to make the positioning tooth disengage from the tooth groove, and the sliding plug can move under the tension of the spiral tension spring to reduce the water storage chamber and transmit water outward. The two ends of the spiral tension spring are respectively connected to the sliding plug and the water tank. In this embodiment, the function of the spiral tension spring can be realized by a spiral compression spring, that is, the spiral compression spring is placed on the other side of the sliding plug to apply thrust to the sliding plug.

[0089] Example 5

[0090] Fig.15 Another water storage and water delivery device is shown. The locking mechanism of the water storage and water delivery device includes symmetrical positioning teeth 127 and symmetrical tooth grooves 128 that move with the sliding plug. The tooth grooves 128 are arranged on the rod 121, and the positioning teeth are arranged on two symmetrical telescopic rods. An elastic element is supported between the two telescopic rods 129 to enable the positioning teeth to engage in the tooth grooves with the elastic force of the elastic element to position the sliding plug. In particular, the tooth grooves are inclined as shown in the figure, so that one-way positioning can be achieved, that is, when the positioning teeth engage in the tooth grooves to position the sliding plug, the sliding plug is prevented from moving in the direction of reducing the water storage chamber, and the sliding plug can be pulled downward to expand the water storage chamber to add water to the water storage chamber.

[0091] The unlocking mechanism also includes a force-applying part which is a steam switch provided on the handle. When the force-applying part is pressed, the force-applying part transmits force to the telescopic rod, compressing the elastic element, so that the positioning tooth can be disengaged from the tooth groove, and the sliding plug can move under the tension of the spiral tension spring to reduce the water storage chamber and transmit water outward. The two ends of the spiral tension spring are respectively connected to the sliding plug and the water tank. In this embodiment, the function of the spiral tension spring can be realized by a spiral compression spring, that is, the spiral compression spring is placed on the other side of the sliding plug to apply thrust to the sliding plug.

[0092] Example 6

[0093] Fig.16 Another water storage and water delivery device is shown. The locking mechanism and unlocking mechanism of the water storage and water delivery device are Fig.14 The same as shown in Example 4.

[0094] The difference is that the elastic force applied to the sliding plug is realized by the winding spring 130, and the winding spring and the driving gear 131 shown in the figure are separately assembled on two parallel shafts. The elastic force of the winding spring is applied to the driving gear 131, and the driving gear is engaged with the sliding plug to realize that the sliding plug moves relative to the water tank with the elastic force of the winding spring to reduce the volume of the water storage chamber. The winding spring can output a relatively stable elastic force.

[0095] Example 7

[0096] Fig.17 Another water storage and water delivery device is shown. The locking mechanism and unlocking mechanism of the water storage and water delivery device are Fig.14 The same as shown in Example 4.

[0097] The difference is that the winding spring 130 exerting elastic force on the sliding plug is coaxially assembled with the driving gear 131. The elastic force of the winding spring 130 is exerted on the driving gear, and the driving gear is engaged with the sliding plug to realize that the sliding plug moves relative to the water tank by the elastic force of the winding spring to reduce the volume of the water storage chamber.

[0098] Example 8

[0099] Figure 18-20 Another water storage and water delivery device is shown. The locking mechanism of the water storage and water delivery device includes a locking ring 132 and a friction surface 123 that moves with the sliding plug. The locking ring itself is elastic. The locking ring uses its own elastic force to hold the sliding plug tightly on the friction surface to position the sliding plug. In specific implementation, other elastic elements may act on the locking ring to apply elastic force to the locking ring to hold the friction surface. The locking ring 132 has an opening 133 and an expansion piece 134 is configured for the opening. As shown in the figure, the opening 133 is formed by two symmetrical ears 135, and the two symmetrical ears are inclined. The expansion piece 134 is located in the opening 133 and cooperates with the ears. In the natural state, the locking ring 132 relies on elastic force to hold the friction surface 123 to lock the sliding plug, and the sliding plug cannot move relative to the box.

[0100] The unlocking mechanism also includes a force-applying part which is a steam switch arranged on the handle. When the force-applying part is pressed, the force-applying part transmits force to the expansion member 134. When the expansion member 134 opens the two symmetrical ears 135, the locking ring 132 releases the friction surface, and the sliding plug can move relative to the box body.

[0101] The expansion piece and the ear edge cooperate with each other through the inclined surface, and the two symmetrical ear edges 135 are spread apart through the mutual movement of the two. Therefore, the inclined surface can also be formed on the expansion piece. After the two symmetrical ear edges 135 are spread apart, the expansion piece can be reset by the elastic force of the locking ring, and a reset spring can also act on the expansion piece.

[0102] The water storage and water delivery devices of the above embodiments show the situation that the water tank is fixed and the sliding plug is movable, wherein the locking structure locks the sliding plug, which is a relatively compact structure. However, since water can be delivered by reducing the volume of the water storage chamber, in actual implementation, the sliding plug can be fixed and the water tank can be movable, and the locking structure can lock the box body.

[0103] Furthermore, the water storage and water delivery device mentioned above is fixedly assembled on the shell, and in specific implementation, it can also be removed from the casing to perform energy storage operations and water addition separately according to needs, and then installed back into the shell.
