[0032] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides an exhibition cabinet for selling Internet of Things devices, including an exhibition cabinet body 1, wherein a water injection chamber 11 and a reflux chamber 12 are arranged side by side on the top of the exhibition cabinet body 1, and a transparent water inlet pipe 2 and a transparent water outlet pipe 3 are vertically arranged on the top of the exhibition cabinet body 1, and the bottom ends of the transparent water inlet pipe 2 and the transparent water outlet pipe 3 are connected to the water injection chamber 11 and the reflux chamber 12 respectively, and the Internet of Things smart valve 4 is connected to the top of the transparent water inlet pipe 2 and the transparent water outlet pipe 3. A pressurizing mechanism 5 for pressurizing the inside of the water injection chamber 11 is provided on the exhibition cabinet body 1, and a hose 13 is connected to the bottom end of the transparent water inlet pipe 2, and the hose 13 extends into the bottom of the water injection chamber 11, and a liquid medium is injected into the water injection chamber 11. The Internet of Things smart valve 4 to be exhibited is assembled on the transparent water inlet pipe 2. Between the tube 2 and the top of the transparent water outlet pipe 3, the pressurizing mechanism 5 is used to apply pressure toward the water injection chamber 11. The liquid medium in the water injection chamber 11 is pressurized and injected into the transparent water inlet pipe 2 through the hose 13, and then flows through the Internet of Things smart valve 4 and the transparent water outlet pipe 3 back to the reflux chamber 12, forming a liquid medium circulation. It is only necessary to control the opening and closing of the Internet of Things smart valve 4. Through the transparent transparent water inlet pipe 2 and the transparent water outlet pipe 3, the flow phenomenon of the liquid medium and the interception effect of the Internet of Things smart valve 4 can be intuitively displayed, so that buyers can intuitively understand the performance of the Internet of Things smart valve 4, and have a good exhibition effect of the Internet of Things smart valve 4. In addition, during the exhibition process, the liquid medium can be recycled and reused, avoiding the phenomenon of liquid medium outflow affecting the exhibition environment.

[0033] like Figures 1 to 3 As shown, the bottom of the exhibition cabinet 1 has a storage cavity 14, and a multi-layer shelf 15 is provided in the storage cavity 14. A cabinet door 8 is installed at a position corresponding to the storage cavity 14 on the side wall of the exhibition cabinet 1, which can be used to store the Internet of Things smart valve 4 and auxiliary tools for exhibition and sales. The top of the transparent water inlet pipe 2 and the transparent water outlet pipe 3 are connected with an elbow joint 16, and the top of the elbow joint 16 is provided with a first flange 17 for assembling and connecting the Internet of Things smart valve 4. Both ends of the transparent water inlet pipe 2 and the transparent water outlet pipe 3 are provided with a second flange 18 for assembling and connecting the transparent water inlet pipe 2 and the transparent water outlet pipe 3 with the elbow joint 16 and the exhibition cabinet 1.

[0034] like Figures 1 to 4 As shown, the pressurizing mechanism 5 includes an air cylinder 19 and an electric push rod 22 vertically mounted on the side wall of the display cabinet 1. The air outlet end of the air cylinder 19 is connected to the top of the water injection chamber 11. The electric push rod 22 drives the air cylinder 19 to exhaust and pressurize the interior of the water injection chamber 11. Specifically, the electric push rod 22 extends and retracts to drive the air cylinder 19 to perform piston motion, thereby achieving the pumping and exhausting of the air cylinder 19. Both ends of the air cylinder 19 and the electric push rod 22 are equipped with a sleeve 20, and the sleeve 20 is provided with an ear block 21 that is bolted to the side wall of the display cabinet 1.

[0035] like Figure 1 and Figure 5 As shown, transparent observation windows 6 are provided on the side walls of the display cabinet 1 at positions corresponding to the water injection chamber 11 and the reflux chamber 12. The display cabinet 1 is also equipped with a drainage mechanism 7 for discharging the liquid medium from the water injection chamber 11 and the reflux chamber 12. The drainage mechanism 7 includes a first drainage pipe 23 and a second drainage pipe 24 extending through the side walls of the display cabinet 1. The first drainage pipe 23 and the second drainage pipe 24 are connected to the water injection chamber 11 and the reflux chamber 12, respectively. A three-way valve 25 is installed between the first drainage pipe 23 and the second drainage pipe 24. The first drainage pipe 23, the second drainage pipe 24, and the three-way valve 25 cooperate to discharge the liquid medium from the water injection chamber 11 and the reflux chamber 12. A pressure gauge 10 is installed on the top of the display cabinet 1 for monitoring the internal pressure of the water injection chamber 11. This allows the pressure in the water injection chamber 11 to be observed while the interception effect of the IoT smart valve 4 is being displayed, thereby better demonstrating the performance of the IoT smart valve 4. The top of the exhibition cabinet 1 is also provided with a controller 9 connected to the pressure gauge 10 and the electric push rod 22.

[0036] The working principle of the technical solution provided by the utility model is as follows:

[0037] During use, liquid medium is injected into the water injection chamber 11, and the Internet of Things smart valve 4 to be exhibited is assembled between the top of the transparent water inlet pipe 2 and the transparent water outlet pipe 3, and the electric push rod 22 is started to drive the air cylinder 19 to pressurize the water injection chamber 11. The liquid medium in the water injection chamber 11 is pressurized and injected into the transparent water inlet pipe 2 through the hose 13, and then flows through the Internet of Things smart valve 4 and the transparent water outlet pipe 3 back to the reflux chamber 12, forming a liquid medium circulation. At this time, by controlling the opening and closing of the Internet of Things smart valve 4, the transparent water inlet pipe 2 and the transparent water outlet pipe 3 can be used to intuitively display the flow phenomenon of the liquid medium and the interception effect of the Internet of Things smart valve 4, so that buyers can intuitively understand the performance of the Internet of Things smart valve 4, and have a good exhibition effect of the Internet of Things smart valve 4. In addition, during the exhibition process, the liquid medium can be recycled and reused through the cooperation of the first drain pipe 23, the second drain pipe 24 and the three-way valve 25, thereby avoiding the phenomenon that the liquid medium flows out and affects the exhibition environment.

[0038] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
