Description

Technical Field

[0001] The utility model belongs to the technical field of washing equipment, and particularly relates to an intelligent foam hand soap robot. Background Art

[0002] Hand sanitizer is a type of cleaning product that people often use in their daily lives and is usually placed in kitchens, bathrooms, and other places. Hand sanitizer is generally stored in a container and is squeezed out of the container by pressing a pressing device set on the top of the container. When washing hands, the squeezed hand sanitizer is usually applied to the area to be washed, rubbed repeatedly by both parties until foaming, and then rinsed with tap water. There are several disadvantages to washing hands using the above method. First, it is difficult to control the amount of hand sanitizer used, resulting in insufficient hand sanitizer from one press and the need for multiple presses, or excessive presses resulting in a waste of hand sanitizer and tap water; second, when manually pressing the hand sanitizer, bacteria and dirt on the hands may contaminate the hand sanitizer container, causing secondary contamination.

[0003] Based on the above problems, the utility model patent with authorization announcement number CN 208677223 U discloses an automatic foam hand soap machine, including: a body and a liquid storage bottle connecting mechanism, the body including: a shell, a nozzle, a first pipette, a foam generating device and a sensing device; the nozzle is arranged on the upper part of the body and is suitable for being arranged toward the outside of the shell to spray foam hand soap; the first pipette is arranged on the body and passes through at least a part of the shell to connect the inside and outside of the shell; the foam generating device is arranged inside the shell; the sensing device is arranged on the body and connected to the foam generating device, the sensing device is used to detect an approaching human body, and generates the start signal after detecting the approaching human body; the liquid storage bottle connecting mechanism is suitable for assembling the liquid storage bottle on the body and making the liquid storage bottle and the shell form an integral whole.

[0004] Although the above-mentioned automatic foam hand sanitizer machine solves the problem of difficulty in controlling the amount of hand sanitizer and secondary pollution through intelligent control, the above-mentioned foam hand sanitizer machine still has the following defects: the hand sanitizer in the storage bottle cannot be completely used up by sucking the hand sanitizer through the pipette, resulting in waste; the foam generating device includes a driving motor, an interface component, an elastic component, a valve component and a transmission mechanism, and the structure is relatively complex. After repeated operation, the elastic component is easily damaged, resulting in the hand sanitizer being unable to spray normally; it is impossible to monitor the capacity of the hand sanitizer in the storage bottle, and it is impossible to monitor whether the hand sanitizer in the used or replaced hand sanitizer tank is a counterfeit product; the nozzle is located at the upper part of the foam hand sanitizer machine, and the foam is easily sprayed on the machine body when spraying, causing contamination of the machine body, and the structure of the foam generating device.

DETAILED DESCRIPTION

[0023] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with embodiments. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Refer to the attached Figure 1 and attached Figure 2 As shown, the utility model relates to an intelligent foam hand soap robot comprising a body 1, a liquid storage bottle 2, a pump head 3 and a driving mechanism.

[0025] The lower portion of the housing 1 is provided with a mounting platform 11, and the pump head is fixed within the mounting platform 11. Specifically, a pump head slot 15 is provided within the mounting platform 11, and the pump head is fixed within the pump head slot 15 of the mounting platform. The pump head comprises a gas chamber cover 3, a valve body 4, and a liquid mixing chamber 5. The gas chamber cover is provided with an inner cavity 31 and an outer cavity. The inner cavity 31 comprises, from top to bottom, a large-diameter portion 33 and a small-diameter portion 34 that are interconnected. The upper half of the large-diameter portion 33 is formed into a bell-shaped mouth 35. The upper portion of the valve body 4 extends into the inner cavity 31 of the gas chamber cover 3. The valve body 3 is provided with an upper sealing ring 41 at the large-diameter portion 33 and a lower sealing ring 42 at the small-diameter portion 34. The lower portion of the valve body 4 extends into the liquid mixing chamber 5. The outer ring of the bottom of the valve body 4 is fixed to the inner ring of the liquid mixing chamber 5, thereby forming a mixing chamber. The outer cavity of the gas chamber cover 3 is sealed outside the liquid mixing chamber 5 to form a sealed chamber 51. The valve body 4 is provided with a through hole 43 connecting the inside and outside of the valve body at the position of the sealed chamber 51, so that the hollow portion of the sealed chamber 51 is connected to the mixing chamber of the liquid mixing chamber 5. A foam core 8 is installed in the mixing chamber, and a mesh fabric is provided at both ends of the foam core 8 to mix the liquid and air into foam.

[0026] The driving mechanism is connected with the liquid mixing chamber 5 by snapping, and is used to drive the liquid mixing chamber 5 to move up and down. Figure 2 and attached Figure 3 As shown: the driving mechanism includes a turntable 6 and a tray 7 driven by a motor (not shown in the figure), and the tray 7 is eccentrically arranged on the front of the turntable 6. An eccentric protrusion is provided on the front of the turntable 6, and an annular protrusion is provided on the back of the tray 7. The annular protrusion on the back of the tray contacts the eccentric protrusion on the front of the turntable, so that when the turntable 6 drives the eccentric protrusion to rotate, the annular protrusion and the eccentric protrusion are connected by relative sliding. Since the eccentric protrusion is eccentrically arranged, the annular protrusion will also be driven to move up and down when the annular protrusion and the eccentric protrusion slide relative to each other, thereby causing the tray 7 to move up and down, and the front of the tray 7 is buckled and fixed to the liquid outlet mixing bin 5.

[0027] Refer to the attached Figure 2 As shown, the liquid storage bottle 2 is inverted on the mounting platform 11, and the gas compartment cover 3 of the pump head is pressed and fixed with the bottle mouth of the liquid storage bottle 2, so that the liquid storage bottle 2 is connected with the top of the pump head.

[0028] Refer to the attached Figure 2As shown, an infrared sensor 9 is provided at the bottom of the fuselage 1 for sensing the liquid taken by human hands. The above-mentioned driving mechanism and infrared sensor 9 are connected to the control chip of the intelligent foam hand sanitizer robot. The working principle of the intelligent foam hand sanitizer robot is as follows: when the hand approaches from the bottom of the fuselage 1, the infrared sensor 9 senses the hand and sends a signal to the control chip. After receiving the signal, the control chip sends a control signal to the driving mechanism. The motor drives the turntable 6 to rotate one circle. The magnet provided on the turntable 6 and the magnetic induction device provided on the fuselage 1 near the turntable 6 are used for identification and precise control so that the motor drives the turntable 6 to rotate one circle each time. During this process, the eccentrically arranged card holder 7 moves up and down one back and forth; in the process of moving upward, the connected liquid mixing chamber 5 and valve body 4 move upward first, and the gas chamber cover 3 is fixed, so that the air and hand sanitizer in the sealing chamber 51 are squeezed and quickly enter the mixing chamber of the valve body 4 from the through hole 43, and in the mixing chamber. The liquid just squeezed in is brought into the sealed chamber 51 until the upper sealing ring 41 returns to the large diameter part 33 and the lower sealing ring 42 returns to the small diameter part 34. The liquid storage bottle 2 stops conveying hand sanitizer to the sealed chamber 51, and the sealed chamber 51 waits for the next use.

[0029] In the present invention, the liquid storage bottle 2, the chip and the pump head are disposable and need to be replaced with a new liquid storage bottle 2 after use. Figure 2 and attached Figure 3 As shown, a chip reader 12 is provided above the mounting platform 11, and a chip 21 is provided at the bottom of the liquid storage bottle 2. When the liquid storage bottle 2 is inverted on the mounting platform 11, the position of the chip 21 corresponds to the position of the chip reader 12. After replacing the liquid storage bottle 2, the chip reader 12 is used to read the chip 21, which can ensure that the replaced hand sanitizer is the hand sanitizer specified by the manufacturer. At the same time, the amount of hand sanitizer used, production date, shelf life, and other information can be detected to avoid the use of counterfeit products. After the chip reader 12 reads the chip 21 information for the first time, the control chip of the intelligent foam hand sanitizer robot initializes the number of uses of the liquid storage bottle 2 to 0, and updates the number of uses after each use to detect the remaining amount of hand sanitizer in the liquid storage bottle 2. The liquid storage bottle 2 can also be provided with a liquid level sensor inside to detect the remaining amount of hand sanitizer in the liquid storage bottle 2.

[0030] Refer to the attached Figure 1 and 2As shown, the front panel of the body 1 is provided with a strip-shaped ambient light 13, in which a plurality of lamp beads 14 are arranged vertically. As the foam hand soap is sprayed from the valve body 4 to the liquid mixing chamber 5, the strip-shaped ambient light 13 lights up and goes out in sequence from top to bottom, forming a meteor-like shape, giving the user the intuitive feeling of a meteor turning into foam spraying.

[0031] The above describes the present invention in detail with reference to the embodiments. However, the above contents are only preferred embodiments of the present invention and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
