[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The air pressure detector in the prior art is fixedly connected to the hose. When the hose is damaged after long-term use or punctured by a sharp object, the entire device needs to be replaced, which wastes undamaged parts and greatly increases the cost of repair and replacement. The following describes a water tank leak detector provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] In order to increase the service life of the device, combined Figure 1-Figure 4 As shown, a water tank leak detector is proposed. An air filling mechanism 1 is provided, and air is filled into the water tank through the air filling mechanism 1. A pressure measuring mechanism 2 is provided at one end of the air filling mechanism 1, and the pressure change inside the water tank is detected through the pressure measuring mechanism 2. A connecting mechanism 3 is provided on one side of the pressure measuring mechanism 2, and a fixing mechanism 4 is provided on one side of the connecting mechanism 3. The connecting mechanism 3 and the fixing mechanism 4 cooperate with each other to communicate with the sealed water tank, and the water tank is leak-detected through the cooperation of multiple mechanisms.

[0026] In order to avoid replacement of the entire device when components are damaged, an inflation mechanism 1, a pressure measuring mechanism 2, a connecting mechanism 3, and a fixing mechanism 4 are proposed. An inflation tube 101 is installed, and an inner wall of one end of the inflation tube 101 is provided with an internal thread a102. A fixing ring a203 and a fixing ring b204 are installed, and one side of the fixing ring a203 is fixedly connected with an external threaded thin wall, and an inner wall of the fixing ring b204 is provided with an internal thread b205. A connecting tube 201 is fixedly connected between the fixing rings a203 and b204, and an air pressure detection gauge 202 is installed on the connecting tube 201. A connecting ring a302 and a connecting ring b304 are installed, and external threads a303 and external threads b305 are respectively provided on the outer sides of the connecting rings a302 and b304. A hose 301 is fixedly connected between the connecting rings a302 and b304. Wall 401, the inner wall of the circular thin wall 401 is provided with an internal thread c402, the water tank mouth is first sealed by the water tank mounting part 404, the circular thin wall 401 is installed and connected with the connecting ring b304, at this time, the water tank is inflated through the inflation tube 101, and whether there is leakage inside the water tank is judged by observing the value change of the air pressure detection meter 202, the inflation tube 101 and the external thread thin wall are threadedly connected through the internal thread a102 and the external thread thin wall, the fixing ring b204 and the connecting ring a302 are threadedly connected through the internal thread b205 and the external thread a303, the connecting ring b304 and the circular thin wall 401 are threadedly connected through the external thread b305 and the internal thread c402, when a component of the device is damaged, the single mechanism can be repaired and replaced, which reduces the maintenance cost, increases the service life of the device, and is more portable and practical.

[0027] Embodiment 2:

[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that the air pressure detector and the hose 301 in the prior art are both fixedly connected. When the hose 301 is damaged, the entire device needs to be replaced, which causes great waste and increases cost losses. However, when multiple mechanisms can be easily installed and fixed, the connection effect between the mechanisms should be further increased to ensure the airtightness of the device when it is used.

[0029] Combination Figure 1-Figure 4 As shown, gaskets are installed on the inner wall of the inflation tube 101, the fixing ring b204 and the circular thin wall 401. The gaskets make the installation connection between the inflation tube 101 and the external threaded thin wall, between the fixing ring b204 and the connecting ring a302, and between the connecting ring b304 and the circular thin wall 401 tighter, avoiding leakage at the connection of the device during the detection process. At the same time, circular holes are opened on multiple gaskets to avoid affecting the air circulation between multiple mechanisms, thereby ensuring the detection effect of the device.

[0030] An air outlet pipe 403 is fixedly connected to the bottom of the circular thin wall 401, and a water tank mounting part 404 is fixedly connected to the bottom of the air outlet pipe 403. Air outlet holes are provided on the water tank mounting part 404 and the bottom wall of the circular thin wall 401. The water tank mounting part 404 and the circular thin wall 401 are regarded as a whole through the air outlet pipe 403. When leak testing the water tank of different models, the whole can be replaced accordingly.
