Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically a pressure regulating device for a compact cleaning machine. Background Technology

[0002] A cleaning machine is a device used to clean the surface of an object. Depending on the cleaning method, it can be divided into intelligent cleaning machines, laser cleaning machines, and high-pressure cleaning machines. A compact cleaning machine is a type of cleaning machine with a compact design. These machines are small in size, making them easy to store and move. When using a compact cleaning machine, the water pressure used for rinsing is adjusted by a pressure regulating device installed on the machine.

[0003] Traditional compact cleaning machines use a throttle handle to adjust the pressure. However, once the appropriate pressure is reached, the handle lacks a limit switch, making it susceptible to external force affecting pressure. Therefore, we propose an improved pressure adjustment device for compact cleaning machines to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a pressure regulating device for a compact cleaning machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure regulating device for a compact cleaning machine, comprising a pressure regulator, threaded connection ports on both sides of the pressure regulator, a handle at the top of the pressure regulator, a protective seat on the outer wall of the handle, the bottom end of the protective seat being fixed to the top of the pressure regulator, threaded rods movably disposed at the top of both sides inside the protective seat, a rotating block installed on one side of each threaded rod, a locking block installed on the other side of each threaded rod, and a pressure gauge installed at the front end of the pressure regulator.

[0006] Preferably, the locking blocks are provided in two sets, and the two sets of locking blocks are symmetrically distributed about the central axis of the throttle.

[0007] Preferably, the protective seat has internal threads evenly arranged on both sides inside, and the protective seat and the threaded rod form a threaded connection.

[0008] Preferably, a knob is installed on one side of the pressure gauge, and a second gear is movably arranged inside the knob via a rotating shaft. A first gear is arranged on one side of the second gear, and the first gear is movably arranged inside the pressure gauge. A scraper is installed inside the first gear.

[0009] Preferably, the rotating shaft and the gear mesh with each other, and the scraper is made of a transparent material.

[0010] Preferably, a rotating ring is movably provided on the outer wall of each threaded connection, and a sealing protective sleeve is fixed on the outer wall of each rotating ring, and a sealing ring is installed inside each sealing protective sleeve.

[0011] Preferably, the inner sidewall of the rotating ring is uniformly provided with internal threads, and the outer sidewall of the threaded connection port is uniformly provided with external threads, thus forming a threaded connection between the rotating ring and the threaded connection port.

[0012] Preferably, the sealing protective sleeve is provided in two sets, and the two sets of sealing protective sleeves are symmetrically distributed about the central axis of the pressure regulator.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the pressure regulating device of this compact cleaning machine not only realizes the limiting of the throttle used to regulate the pressure and facilitates the scraping of water mist adhering inside the pressure gauge, but also greatly increases the sealing performance of the connection between the pressure regulator and the pipeline.

[0014] (1) By setting up components such as a protective seat, locking block, threaded rod and rotating block, the pressure regulator can be adjusted by rotating the handle when in use. After the handle is rotated to the required pressure, the above-mentioned components can limit and lock the handle when it is rotated to the required position, so as to avoid external forces from accidentally touching the handle and affecting the use of the pressure regulator.

[0015] (2) By setting up components such as knob, gear 2, shaft and scraper, the pressure regulator displays the corresponding pressure data through pressure gauge when in use. If moisture is generated inside the pressure gauge and affects the reading of the data inside the pressure gauge, the above-mentioned components can scrape off the water mist on the surface of the pressure gauge without the aid of electricity, thereby realizing the water mist scraping function of the pressure regulator.

[0016] (3) By setting up components such as sealing rings, sealing protective sleeves and rotating rings, when the pressure regulator is used, after the corresponding cleaning machine pipes are installed inside the threaded connection ports on both sides, the cooperation of the above components can seal and protect the connection between the threaded connection ports and the external pipes, which greatly increases the sealing performance of the pressure regulator installation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a pressure regulating device for a compact cleaning machine, including a pressure regulator 1. Threaded connection ports 5 are provided on both sides of the pressure regulator 1. A handle 4 is provided at the top of the pressure regulator 1. A protective seat 3 is provided on the outer wall of the handle 4, and the bottom end of the protective seat 3 is fixed to the top of the pressure regulator 1. Threaded rods 15 are movably provided at the top of both sides inside the protective seat 3. A rotating block 16 is installed on one side of each threaded rod 15, and a locking block 14 is installed on the other side of each threaded rod 15. A pressure gauge 9 is installed at the front end of the pressure regulator 1. Two sets of locking blocks 14 are provided, and the two sets of locking blocks 14 are symmetrically distributed about the central axis of the handle 4, making the locking of the handle 4 more stable. Internal threads are evenly provided on both sides inside the protective seat 3, and a threaded connection is formed between the protective seat 3 and the threaded rod 15, which pushes the locking block 14 to move stably towards the handle 4.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after adjusting the pressure regulator 1 to the required pressure by rotating the handle 4, the threaded rods 15 on both sides of the inner side of the protective seat 3 are rotated by holding the rotating block 16 in sequence. The rotation of the threaded rods 15 drags the locking block 14 toward the surface of the handle 4 and fits against the surface of the handle 4, thereby limiting and locking the handle 4 when it is rotated to the required pressure level, and ensuring the stability of the pressure of the pressure regulator 1.

[0025] A knob 8 is installed on one side of the pressure gauge 9. A gear 2 11 is movably installed inside the knob 8 via a rotating shaft 12. A gear 10 is installed on one side of the gear 2 11 and is movably installed inside the pressure gauge 9. A scraper 13 is installed inside the gear 10. The rotating shaft 12 and the gear 10 mesh with each other. The scraper 13 is made of transparent material. The transparent design does not affect the reading of the data inside the pressure gauge 9.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, when water mist inside the pressure gauge 9 affects data reading, rotating the shaft 12 causes gear 11 to rotate. The rotation of gear 11 drives gear 10, which is meshed on one side, to rotate inside the pressure gauge 9. After gear 10 rotates inside the pressure gauge 9, it drives the scraper 13 to rotate against the inner surface of the pressure gauge 9, scraping away the water mist generated on the inner surface of the pressure gauge 9, thereby removing the water mist and allowing the data of the pressure gauge 9 to be read normally.

[0027] Rotating rings 7 are movably provided on the outer side wall of threaded connection port 5. Sealing protective sleeves 6 are fixed on the outer side wall of rotating rings 7. Sealing rings 2 are installed inside the sealing protective sleeves 6. Internal threads are uniformly provided on the inner side wall of rotating rings 7. External threads are uniformly provided on the outer side wall of threaded connection port 5. Threaded connection is formed between rotating rings 7 and threaded connection port 5. Two sets of sealing protective sleeves 6 are provided. The two sets of sealing protective sleeves 6 are symmetrically distributed about the central axis of pressure regulator 1, which provides better sealing protection between threaded connection port 5 and cleaning machine pipeline.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, after the corresponding cleaning machine pipes are installed inside the threaded connection ports 5 on both sides of the pressure regulator 1, the sealing protective sleeve 6 is rotated so that it moves towards the connected external pipe through the rotation of the rotating ring 7 on the outer wall of the threaded connection port 5 until the sealing protective sleeve 6 fits into the connection between the threaded connection port 5 and the cleaning machine pipe. Then, the connection is sealed and protected by the combined action of the sealing protective sleeve 6 and the sealing ring 2.

[0029] Working principle: When using this utility model, after the threaded connection ports 5 on both sides of the pressure regulator 1 are installed together with the corresponding pipes of the cleaning machine, the sealing protective sleeve 6 is rotated so that it is fitted to the connection between the threaded connection port 5 and the external pipe by the rotation of the rotating ring 7 on the outer wall of the threaded connection port 5. The sealing protective sleeve 6 and the sealing ring 2 work together to seal and protect the connection. By rotating the handle 4, the pressure regulator 1 is operated to adjust the cleaning machine to a suitable pressure. After the pressure is adjusted by the handle 4, the threaded rods 15 on both sides inside the protective seat 3 are rotated by holding the rotating block 16 in sequence. The rotation of the threaded rods 15 drags the locking block 14 to move towards the surface of the handle 4 and fits against the surface of the handle 4, limiting and locking the handle 4 when it is rotated to the required pressure, ensuring the stability of the pressure adjusted by the pressure regulator 1.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
