[0004] To achieve the above objectives, this utility model provides the following technical solution: a liquid detergent dispensing device for a laundry room, comprising a storage cylinder with an open upper end. A ring is fitted around the upper end of the storage cylinder and fixed to it. A cylinder cover is provided on the upper side of the ring, with a circular hole at the center of the upper surface of the cover. A vertically arranged electric push rod is provided on the upper side of the cover. The movable end of the electric push rod passes through the circular hole and is fitted with a piston, which is slidably installed inside the storage cylinder. A first bent pipe and a second bent pipe are installed at the bottom of the storage cylinder. A first one-way valve for connecting a suction pipe is installed at the end of the first bent pipe away from the storage cylinder, and the first one-way valve is open towards the first bent pipe. A second one-way valve for connecting a drain pipe is installed at the end of the second bent pipe away from the storage cylinder, and the second one-way valve is open away from the second bent pipe. A support plate is fitted around the cylinder body of the electric push rod and fixed to it, and the support plate is fixed to the cylinder cover via a connector.

[0005] Furthermore, the connector includes a positioning post. The upper surface of the ring has multiple lower positioning holes equidistantly arranged in a ring. The upper surface of the cylinder cover has multiple upper positioning holes equidistantly arranged in a ring, aligned with the lower positioning holes. A positioning post is inserted into the channel formed by the upper and lower positioning holes. A limit strip is fixedly connected to the lower end of the positioning post. The end of the positioning post away from the limit strip extends to the upper side of the cylinder cover. An insertion port is provided at the upper part of one side of the positioning post. The top of the insertion port is an inclined surface that slopes away from the center of the cylinder cover. A horizontal plate is inserted into the insertion port. A screw hole is provided on the upper surface of the horizontal plate away from the positioning post. The upper surface of the support plate has multiple small holes equidistantly arranged in a ring, which mate with the screw holes. A screw is inserted into the small hole. The lower end of the screw passes through the small hole and is threaded into the screw hole.

[0006] Furthermore, a pad is fixedly connected to the lower surface of the cross plate near the screw hole, and the pad is in contact with the upper surface of the cylinder cover.

[0007] Furthermore, the end of the horizontal plate away from the screw hole is connected and fixed with an inclined block that matches the inclined surface, and the inclined block and the horizontal plate are an integral horizontal structure.

[0008] Furthermore, an L-shaped plate is fixedly connected to the upper surface of the horizontal plate near the screw hole. The upper surface of the horizontal part of the L-shaped plate has a through hole aligned with the screw hole, and the screw passes through the through hole.

[0011] Furthermore, the upper surface of the support plate is provided with multiple openings at equal intervals in a ring shape, and the openings and small holes are arranged alternately.

[0012] The beneficial effects of this utility model are:

[0013] 1. Insert the positioning pin into the channel formed by the lower and upper positioning holes, and make the limiting strip contact the lower surface of the ring. Then, insert the horizontal plate into the insertion port of the positioning pin. The structure formed by multiple sets of horizontal plates and positioning pins cooperates with each other to restrict the relative position of the cylinder cover and the ring, that is, restrict the relative position of the cylinder cover and the liquid storage cylinder. Make the multiple small holes on the support plate aligned with the screw holes on the multiple horizontal plates, and make the screws pass through the small holes and screw them into the screw holes to fix the relative position of the electric push rod and the cylinder cover. It is not necessary to use multiple screws to connect the cylinder cover and the liquid storage cylinder, or to use multiple screws to connect the electric push rod and the cylinder cover, thus reducing the number of screws used.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a liquid cleaning agent dispensing device for a laundry room, including a liquid storage cylinder 1 with an open upper end, a ring 6 fixedly connected to the upper end of the liquid storage cylinder 1, a cylinder cover 12 on the upper side of the ring 6, a circular hole 17 in the middle of the upper surface of the cylinder cover 12, a vertically arranged electric push rod 10 on the upper side of the cylinder cover 12, the movable end of the electric push rod 10 passing through the circular hole 17 and fitted with a piston 14, wherein a disc 13 is fixedly connected to the upper surface of the piston 14, and a sleeve 15 is fixedly connected to the middle of the upper surface of the disc 13, so that the movable end of the electric push rod 10 is installed in the sleeve 15, improving the stability of the connection between the electric push rod 10 and the disc 13, and increasing the connection range between the electric push rod 10 and the piston 14.

[0026] See Figures 1-4 The piston 14 is slidably installed inside the liquid storage tank 1. A first bent pipe 2 and a second bent pipe 4 are installed at the bottom of the liquid storage tank 1. A first one-way valve 3 for connecting to the suction pipe is installed at the end of the first bent pipe 2 away from the liquid storage tank 1. The first one-way valve 3 is open towards the first bent pipe 2. A second one-way valve 5 for connecting to the drain pipe is installed at the end of the second bent pipe 4 away from the liquid storage tank 1. The second one-way valve 5 is open away from the second bent pipe 4. When the electric push rod 10 retracts, it drives the piston 14 to slide upward inside the liquid storage tank 1. At this time, under the action of negative pressure inside the liquid storage tank 1, the first one-way valve 3 opens and the second one-way valve 5 closes. Then, the liquid cleaning agent is drawn into the liquid storage tank 1. When the electric push rod 10 extends, the piston 14 squeezes the liquid cleaning agent in the liquid storage tank 1. At this time, the first one-way valve 3 closes and the second one-way valve 5 opens, so that the liquid cleaning agent in the liquid storage tank 1 flows into the washing equipment through the drain pipe. Repeat the above operation to realize the dispensing of liquid cleaning agent.

[0027] See Figures 1-7The electric push rod 10 has a support plate 9 fixedly connected to the cylinder body end. The upper surface of the support plate 9 has multiple annularly spaced openings 27, which are alternately arranged with small holes 26. The openings 27 reduce the material consumption of the support plate 9. The upper surface of the ring 6 has multiple annularly spaced lower positioning holes 16 with rectangular cross-sections. The upper surface of the cylinder cover 12 has multiple annularly spaced upper positioning holes 18 with rectangular cross-sections aligned with the lower positioning holes 16. A positioning post 7 with a rectangular cross-section is inserted into the channel formed by the upper positioning holes 18 and the lower positioning holes 16. A limit strip 20 is fixedly connected to the lower end of the positioning post 7. The end of the positioning post 7 away from the limit strip 20 extends to the upper side of the cylinder cover 12. An insertion port 19 is provided on the upper part of one side of the positioning post 7. The top of the insertion port 19 is an inclined surface sloping away from the center of the cylinder cover 12. A horizontal plate 11 is inserted into the socket 19. The end of the horizontal plate 11 away from the screw hole 23 is connected and fixed with an inclined block 25 that cooperates with the inclined surface. The inclined block 25 and the horizontal plate 11 are an integral horizontal structure. The inclined block 25 cooperates with the inclined surface to drive the positioning rod of the horizontal plate 11 to move upward. A pad 24 is connected and fixed at the position of the lower surface of the horizontal plate 11 near the screw hole 23. The pad 24 fits against the upper surface of the cylinder cover 12 and supports the horizontal plate 11. The positioning post 7 is inserted into the channel formed by the lower positioning hole 16 and the upper positioning hole 18, and the limiting strip 20 contacts the lower surface of the ring 6. Then, the horizontal plate 11 is inserted into the socket 19 of the positioning post 7. The structure formed by multiple sets of horizontal plates 11 and positioning posts 7 cooperates to restrict the relative position of the cylinder cover 12 and the ring 6, that is, the relative position of the cylinder cover 12 and the liquid storage cylinder 1 is restricted.

[0028] See Figures 1-7 A screw hole 23 is provided on the side of the upper surface of the horizontal plate 11 away from the positioning post 7. A number of small holes 26 that mate with the screw hole 23 are provided in a ring on the upper surface of the support plate 9. Screws 8 are inserted into the small holes 26. The lower end of the screw 8 passes through the small hole 26 and is threaded into the screw hole 23. This makes the multiple small holes 26 on the support plate 9 aligned with the multiple screw holes 23 on the horizontal plate 11, and the screws 8 pass through the small holes 26 and are screwed into the screw holes 23. This fixes the relative position of the electric push rod 10 and the cylinder cover 12. It eliminates the need to use multiple screws 8 to connect the cylinder cover 12 and the liquid storage cylinder 1, as well as to use multiple screws 8 to connect the electric push rod 10 and the cylinder cover 12, thus reducing the number of screws 8 used.

[0029] See Figure 1 , Figure 6 and Figure 7An L-shaped plate 21 is fixed to the upper surface of the horizontal plate 11 near the screw hole 23. The upper surface of the horizontal part of the L-shaped plate 21 has a through hole 22 that is aligned with the screw hole 23. When installing the screw 8, one end of the screw 8 passes through the small hole 26 and the through hole 22 in sequence and is screwed into the screw hole 23. With the support of the L-shaped plate 21, there is a gap between the head of the screw 8 and the horizontal plate 11. When the screw 8 cannot be removed normally due to corrosion or other reasons, the screw 8 can be cut off by using the gap between the horizontal part of the L-shaped plate 21 and the horizontal plate 11.
