[0017] 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.

[0018] See also Figure 1-2 The embodiment of the utility model provides a technical solution: a point-actuated exhaust valve for a grease pump, comprising a device body 1, the device body 1 comprising a grease pump body 2, a small cover frame 3, an oil level switch 4 and a portable exhaust device 5, the small cover frame 3 is mounted at the bottom of the grease pump body 2, the oil level switch 4 is mounted at the left end inside the grease pump body 2, and the portable exhaust device 5 is mounted at the right end inside the grease pump body 2;

[0019] The portable exhaust device 5 comprises an exhaust valve body 6, an exhaust valve core 7, an O-ring 8 and a reset spring 9. The exhaust valve body 6 and the exhaust valve core 7 are both in a T-shaped structure. The exhaust valve core 7 is installed in the exhaust valve body 6, and the reset spring 9 is fixed to the left end of the exhaust valve core 7. There is a group of O-rings 8, and one group of O-rings 8 is respectively installed at the top and bottom of the left end of the exhaust valve core 7. When exhausting, the staff only needs to press the outer end of the exhaust valve core 7 with their fingers to overcome the force of the reset spring 9 to make the exhaust valve core 7 away from the exhaust valve body 6, so that the exhaust channel is opened and the oil and gas can be discharged. When the exhaust is completed, it is automatically closed by the reset spring 9. This method is simple and convenient to operate and has reliable sealing. The O-ring 8 arranged on the exhaust valve core fits the conical sealing surface of the exhaust valve body 6, so that the higher the pressure, the tighter the seal.

[0020] Furthermore, the rear end of the grease pump body 2 is provided with a group of fixing ears 10 distributed in a symmetrical manner. The fixing ears 10 are in a rectangular structure. A fixing limit hole 11 is opened on the surface of the fixing ear 10. The fixing limit hole 11 is in a gourd-shaped structure. The staff can fit the group of fixing ears 10 at the rear end of the grease pump body 2 to the installation point, and then insert the fixing bolts into the fixing limit holes 11 to further fix the whole. The fixing limit holes 11 are in a gourd-shaped structure, which can facilitate fixing with bolts of different sizes.

[0021] Differently, a top cover 12 is fixed on the top of the grease pump body 2, and a feed channel 13 is opened inside the grease pump body 2. The feed channel 13 has a funnel-shaped structure. The staff can add grease into the grease pump body 2 by opening the top cover 12, and the feed channel 13 has a funnel-shaped structure to facilitate the dispersion of the grease after feeding.

[0022] Working principle: When exhausting, the staff only needs to press the outer end of the exhaust valve core 7 with their fingers to overcome the force of the return spring 9 to make the exhaust valve core 7 move away from the exhaust valve body 6. The exhaust channel will be opened and the oil and gas can be discharged. When the exhaust is completed, it will be automatically closed by the return spring 9. This method is simple and convenient to operate and has reliable sealing. The O-ring 8 on the exhaust valve core fits the conical sealing surface of the exhaust valve body 6, so that the higher the pressure, the tighter the seal.

[0023] The utility model comprises 1. a device body; 2. a grease pump body; 3. a small cover frame; 4. an oil level switch; 5. a portable exhaust device; 6. an exhaust valve body; 7. an exhaust valve core; 8. an O-ring; 9. a reset spring; 10. a fixing ear; 11. a fixing limit hole; 12. a top cover; and 13. a feed channel. All the components are general standard components or components known to the technicians in this field, and their structures and principles can be known to the technicians in this field through the technical manual or through conventional experimental methods. The utility model solves the problem that the existing piston-assisted grease pumps generally encounter the problem of air entering the closed oil tank. If there is air, the pump will be empty and cause failure, so the air must be removed. At present, most of them adopt the method of loosening the exhaust plug to exhaust, and then tightening the exhaust plug after the exhaust is completed, which is a relatively troublesome operation. The utility model can effectively exhaust the air in the closed oil tank through the combination of the above components, and the operation method is simple, which is convenient for the staff to operate. After the air is exhausted, the sealing work can be automatically performed, thereby reducing the workload of the staff.

[0024] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
