Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to a valve accessory with pressure display function. Background Technology

[0002] Inflatable products such as surfboards, inflatable boats, and inflatable swimming pools are equipped with inflation valves. The inflation valves are sealed to the inflatable products. An example of an existing inflation valve is the Chinese utility model patent application CN202020974374.4 (authorization announcement number CN212389809U), entitled "An Inflatable Valve". The inflation valve includes a valve body and a valve cover. The valve body has an inner shell and an outer shell. The inner shell has an inflation chamber and an inflation valve port. The outer shell has a working chamber. The inflation chamber and the working chamber are connected through the inflation valve port. A one-way valve core assembly is provided at the inflation valve port. This inflation valve is smaller in size and has a better effect when applied to inflatable products.

[0003] Existing inflation valves can only seal the valve opening on the valve body to prevent air leakage from the inflatable product, and cannot intuitively show the air pressure inside the inflatable product, thus having a single function. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a valve accessory with pressure display function that is suitable for combination with valve port and can be used as valve cover, in view of the current situation of the prior art.

[0006] To save energy and avoid battery replacements, the mounting cavity is equipped with photovoltaic panels to power the barometric pressure monitoring component. The photovoltaic panels absorb sunlight to generate electricity, thereby powering the barometric pressure monitoring component, making it more environmentally friendly, energy-efficient, and sustainable.

[0007] Preferably, the mounting cavity includes an inner cavity and an outer cavity surrounding the outer perimeter of the inner cavity, and the photovoltaic panel is disposed on the outer cavity.

[0008] Preferably, the bottom wall of the inner chamber is provided with an upwardly extending boss, through which the air guide channel passes. This design minimizes the space required for the air guide channel, thus facilitating its sealing; simultaneously, the gap between the boss and the inner wall of the inner chamber can be used to install part of the structure of the air pressure monitoring component.

[0009] Preferably, the air pressure monitoring component includes a circuit board, horizontally disposed above the boss; a sensor disposed on the lower part of the circuit board, facing the air guide channel and used to measure the air pressure in the air guide channel; a display screen disposed on the upper part of the circuit board for displaying the air pressure value; and a battery housed in the gap between the inner wall of the inner cavity and the outer wall of the boss, and the battery is electrically connected to both the circuit board and the photovoltaic panel. With this design, the photovoltaic panel generates electrical energy after being exposed to sunlight, and the electrical energy is stored in the battery, enabling the battery to continuously power the circuit board.

[0010] Preferably, the boss is connected to the circuit board by screws. Using the above method, the air pressure monitoring component is fixedly connected inside the housing.

[0011] Preferably, a sealing ring is provided between the top surface of the boss and the bottom surface of the circuit board to prevent air leakage and ensure that the air pressure read by the sensor is more accurate.

[0012] Preferably, the housing includes a base and a cover that mates with the base, the cover being made of a transparent material. The transparent material of the cover facilitates the photovoltaic panel's absorption of sunlight for power generation and also allows the user to easily observe the pressure reading on the display screen.

[0013] Preferably, the connecting portion includes a connecting ring extending downward from the lower end of the housing, the connecting ring having the transition air passage inside, and the connecting ring having a groove for connecting with the valve port of the inflation valve. The structural design of this connecting portion is based on existing valve covers.

[0014] Preferably, a sealing ring is fitted on the outer wall of the connecting ring.

[0015] Compared with the prior art, the advantages of this utility model are: the valve accessory with pressure display function is similar to the original valve cover. In addition to sealing the valve port on the inflation valve to prevent air leakage of the inflation product, it can also measure the inflation pressure inside the inflation product.

The battery 23 is housed between the side wall of the inner chamber 11a and the outer side wall of the boss 111, and is electrically connected to both the circuit board 21 and the photovoltaic panel 4. The photovoltaic panel 4 absorbs solar energy, converts it into electrical energy, and stores the electrical energy in the battery 23, which then outputs the electrical energy to the circuit board 21.

[0024] like Figure 4As shown, the top surface of the boss 111 has a vertically extending first connecting hole 1111, and the circuit board 21 has a corresponding second connecting hole 211. Screws pass through the first connecting hole 1111 and the second connecting hole 211 to connect the circuit board 21 to the boss 111. The boss 111 and the base 11 are designed as a single unit.

The connecting part 3 includes a connecting ring 31 extending downward from the lower end of the housing 1. The interior of the connecting ring 31 is a transition air passage 3a that can communicate with the air guide channel 111a. The connecting ring 31 is provided with a groove 32 for connecting with the valve port of the inflation valve. When the connecting part 3 is connected to the valve port of the inflation valve, the connecting part 3 can open the valve port of the inflation valve, so that the interior of the inflatable product is connected to the transition air passage 3a and the air guide channel 111a in sequence. In order to improve the sealing performance between the valve accessory of this utility model and the valve port of the inflation valve, an annular groove 311 is provided on the outer wall of the connecting ring 31 near the end of the housing 1.
