[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The embodiments of the present application provide a dispensing device and a cleaning device for dispensing liquid substances, which can solve the problem in the prior art that a plurality of motors are provided in the cleaning agent dispensing device, which increases the weight and volume of the dispensing device, thereby increasing the footprint of the dispensing device. When the moving path is narrow or the installation space is small, such as when passing through a structure with a frame such as a door, it may be difficult to move or install the dispensing device, thereby affecting the transportation and installation of the dispensing device.

[0045] like Figure 1 , Fig.13 and Fig.14As shown, on the one hand, the present application provides a delivery device for delivering liquid substances, which includes a delivery mechanism 1, a driving motor 2, a first linkage gear set 3 and a second linkage gear set 4, wherein the delivery mechanism 1 includes two delivery units, and the delivery units are used to deliver cleaning agents; the first linkage gear set 3 and the second linkage gear set 4 are respectively arranged corresponding to the two delivery units; the driving motor 2 is connected to the first linkage gear set 3 and the second linkage gear set 4 through a transmission mechanism 6, when the driving motor 2 rotates forward, the first linkage gear set 3 is driven to run, so as to drive a corresponding delivery unit to deliver cleaning agents, and when the driving motor 2 rotates reversely, the second linkage gear set 4 is driven to run, so as to drive another corresponding delivery unit to deliver cleaning agents.

[0046] When the delivery device for delivering liquid substances is used, the first linkage gear set 3 and the second linkage gear set 4 are respectively set corresponding to the two delivery units, and the driving motor 2 is connected to the first linkage gear set 3 and the second linkage gear set 4 through the transmission mechanism 6. When the driving motor 2 rotates forward, the first linkage gear set 3 is driven to run, driving the corresponding delivery unit to deliver the cleaning agent, and the second linkage gear set 4 cannot operate normally to drive the other delivery unit, and when the driving motor 2 rotates reversely, the second linkage gear set 4 is driven to run to drive the corresponding delivery unit to deliver the cleaning agent, and the first linkage gear set 3 cannot operate normally, and the cleaning agent in different delivery units is selected and delivered through the forward and reverse rotation of one motor, without setting two motors to control different delivery units respectively, the structure is simple, the occupied space is reduced, and the problem that multiple motors are set in the cleaning agent delivery device in the prior art will increase the weight and volume of the delivery device, thereby increasing the floor space of the delivery device. When the moving path is narrow or the installation space is small, such as passing through a structure with a frame such as a door, it may be difficult to move or install the delivery device, and there is a problem of affecting the handling and installation of the delivery device.

[0047] like Figure 1 and Figure 2 As shown, in some optional embodiments, the transmission mechanism 6 includes a worm 61 and a first transition gear 62, the worm 61 is connected to the drive motor 2 and rotates synchronously with the drive motor 2, the first transition gear 62 is meshed with the worm 61 and connected to the first linkage gear group 3 and the second linkage gear group 4.

[0048] In this embodiment, the structure of the transmission mechanism 6 is specifically described. The transmission mechanism 6 includes a worm 61 and a first transition gear 62, wherein the worm 61 is connected to the drive motor 2 and rotates synchronously with the drive motor 2, the first transition gear 62 is meshed with the worm 61, and is connected to the first linkage gear set 3 and the second linkage gear set 4. The worm gear operation mode is adopted. The worm gear operation not only has a fast speed, but also has a self-locking performance. There will be no reversal in the event of a sudden power failure, which is safer and improves the structural stability of the delivery device for delivering liquid substances.

[0049] like Figure 1 and Figure 2 As shown, in some optional embodiments, the transmission mechanism 6 further includes a second transition gear 63 , which is meshed with the first transition gear 62 and connected to the second linkage gear set 4 .

[0050] In this embodiment, the transmission mechanism 6 also includes a second transition gear 63, which is meshed with the first transition gear 62 and connected to the second linkage gear set 4. Adding a transition gear can prevent the first linkage gear set 3 and the second linkage gear set 4 from being too close to each other and difficult to arrange. At the same time, the rotation direction of the second linkage gear set 4 can be adjusted by the second transition gear 63, so that the first linkage gear set 3 and the second linkage gear set 4 have the same rotation direction.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, the first linkage gear group 3 and the second linkage gear group 4 both include a ratchet assembly 341 and an output gear 342, wherein the ratchet assembly 341 includes a ratchet 3411 and a ratchet wheel 3412 arranged on the ratchet 3411, and the ratchet 3411 is connected to the transmission mechanism 6; the output gear 342 is meshed with the ratchet wheel 3412, and when the drive motor 2 rotates forward, the ratchet 3411 of the first linkage gear group 3 is rotationally connected with the ratchet wheel 3412, and the ratchet 3411 of the second linkage gear group 4 is engaged with the ratchet wheel 3412, and the ratchet 3411 drives the ratchet wheel 3412 to rotate, so as to drive the output gear 342 to rotate.

[0052] In this embodiment, the first linkage gear group 3 and the second linkage gear group 4 both include a ratchet assembly 341 and an output gear 342, the ratchet 3411 is connected to the transmission mechanism 6, and the output gear 342 is meshed with the ratchet 3412. When the drive motor 2 rotates forward, the ratchet 3411 of the first linkage gear group 3 is rotationally connected with the ratchet 3412, and the ratchet 3411 of the second linkage gear group 4 is engaged with the ratchet 3412. The ratchet 3411 drives the ratchet 3412 to rotate, thereby driving the output gear 342 to rotate. When the drive motor 2 rotates reversely, the ratchet 3411 of the second linkage gear group 4 is rotationally connected with the ratchet 3412, and the ratchet 3411 of the first linkage gear group 3 is engaged with the ratchet 3412.

[0053] In this example, when the first linkage gear group 3 and the second linkage gear group 4 are directly connected through the first transition gear 62, the set rotation directions of the ratchet components 341 of the first linkage gear group 3 and the second linkage gear group 4 are opposite; when the first linkage gear group 3 is connected through the first transition gear 62 and the second linkage gear group 4 is connected through the second transition gear 63, the set rotation directions of the ratchet components 341 of the first linkage gear group 3 and the second linkage gear group 4 are the same.

[0054] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in some optional embodiments, a detection component 7 is further included, a boss 621 is provided on the first transition gear 62, and a contact on the detection component 7 is connected to the boss 621 for detecting the number of rotations of the first transition gear 62.

[0055] In this embodiment, the delivery device for delivering liquid substances also includes a detection component 7, a boss 621 is provided on the first transition gear 62, and the contact on the detection component 7 is connected to the boss 621, which is used to detect the number of rotations of the first transition gear 62. When the driving motor 2 drives the first transition gear 62 to rotate forward and reverse, the detection component 7 receives the signal and records the number of liquid delivery. The multiple between the speed of the first transition gear 62 and the output gear 342 is five times. When the first transition gear 62 rotates five times, the output gear 342 rotates one turn, which ensures the accuracy of liquid delivery and improves the accuracy of the delivery amount.

[0056] like Fig.12 , Fig.13 and Fig.14 As shown, in some optional embodiments, the delivery unit includes a delivery chamber 11 and a pull rod 12, wherein the delivery chamber 11 is arranged corresponding to the first linkage gear group 3 or the second linkage gear group 4; the pull rod 12 is arranged in the delivery chamber 11 and connected to the first linkage gear group 3 or the second linkage gear group 4. When the first linkage gear group 3 or the second linkage gear group 4 is running, the pull rod 12 is driven to run to extract the cleaning agent.

[0057] In this embodiment, the two delivery chambers 11 are respectively arranged corresponding to the first linkage gear set 3 and the second linkage gear set 4. A pull rod 12 is provided in each delivery chamber 11 and is connected to the first linkage gear set 3 or the second linkage gear set 4. When the first linkage gear set 3 or the second linkage gear set 4 is running, the pull rod 12 is driven to run to extract the cleaning agent. The structure is simple and easy to manufacture.

[0058] like Fig. 9 , Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, in some optional embodiments, the delivery chamber 11 includes a control chamber 111 and a pumping chamber 112, the pumping chamber 112 is used to store the cleaning agent, and one end of the pull rod 12 connected to the first linkage gear set 3 or the second linkage gear set 4 is located in the control chamber 111, and the other end extends into the pumping chamber 112.

[0059] In this embodiment, the delivery chamber 11 includes a control chamber 111 and a pumping chamber 112, and the pumping chamber 112 is used to store cleaning agent. One end of the pull rod 12 connected to the first linkage gear group 3 or the second linkage gear group 4 is located in the control chamber 111, and the other end extends into the pumping chamber 112. When the first linkage gear group 3 or the second linkage gear group 4 is running, the pull rod 12 is driven to move along the axial direction of the pull rod 12 to pump out the cleaning agent. The chamber of the traditional delivery device is an integrated chamber, which is easy to cause deformation of the cavity due to complex structure and uneven thickness, resulting in leakage and thus affecting the service life. The delivery chamber 11 divides the chamber into a control chamber 111 and a pumping chamber 112, which solves the leakage problem caused by the shrinkage deformation of the pump chamber and extends the service life.

[0060] In this example, a first sealing ring 121 is provided on the end of the pull rod 12 extending into the pumping chamber 112 to facilitate the pumping process. A stopper 14 is provided on the end of the control chamber 111 away from the pumping chamber 112 to prevent debris from entering the control chamber 111 and affecting the operation of the pull rod 12.

[0062] In the present embodiment, the delivery device for delivering liquid substances also includes a gear mounting box 5, the first linkage gear set 3 and the second linkage gear set 4 are both arranged in the gear mounting box 5, and two cams 51 are arranged on the gear mounting box 5, and the two cams 51 are respectively connected to the first linkage gear set 3 and the second linkage gear set 4, and the cam 51 extends into the control cavity 111 and is connected to one end of the pull rod 12 located in the control cavity 111. When the first linkage gear set 3 or the second linkage gear set 4 is running, the pull rod 12 is driven to run through the cam 51, which is convenient for connecting with the pull rod 12 to control the process of the pull rod 12 to suck the cleaning liquid.

[0063] In this example, the slotted opening on the pull rod 12 is aligned with the rotating rod on the cam 51. When the driving motor 2 drives the cam 51 to operate, the pull rod 12 can move forward and backward to pump and discharge liquid.

[0064] In this example, the gear mounting box 5 includes a gear seat 52 and an upper cover 53.

The umbrella valve 1322 is arranged corresponding to the output end of the sealing unit 131, which not only ensures the sealing of the pumping chamber 112 and prevents leakage, but also improves the stability of the chamber, prevents leakage caused by the shrinkage and deformation of the pump chamber, and extends the service life.

[0067] In this example, a third sealing ring 133 is provided between the sealing seat 1311 and the one-way valve 1321, and a fourth sealing ring 134 is provided between the one-way valve 1321 and the pump cover 1312. The shape of the fourth sealing ring 134 matches the shape of the output end of the sealing unit 131, and in this example, it is a double O-type. The sealing seat 1311 and the one-way valve 1321 are both provided with welding ribs, and ultrasonic welding is performed with the pump cover 1312 to ensure firmness and prevent leakage due to inadequate sealing, thereby affecting operation.
